The article overviews some achievements and problems of Korean medical journals published in the highly competitive journal environment. Activities of Korean Association of Medical Journal Editors (KAMJE) are viewed as instrumental for improving the quality of Korean articles, indexing large number of local journals in prestigious bibliographic databases and launching new abstract and citation tracking databases or platforms (eg KoreaMed, KoreaMed Synapse, the Western Pacific Regional Index Medicus [WPRIM]). KAMJE encourages its member journals to upgrade science editing standards and to legitimately increase citation rates, primarily by publishing more great articles with global influence. Experience gained by KAMJE and problems faced by Korean editors may have global implications.

Cardiac magnetic resonance (CMR) imaging is now widely used in several fields of cardiovascular disease assessment due to recent technical developments. CMR can give physicians information that cannot be found with other imaging modalities. However, there is no guideline which is suitable for Korean people for the use of CMR. Therefore, we have prepared a Korean guideline for the appropriate utilization of CMR to guide Korean physicians, imaging specialists, medical associates and patients to improve the overall medical system performances. By addressing CMR usage and creating these guidelines we hope to contribute towards the promotion of public health. This guideline is a joint report of the Korean Society of Cardiology and the Korean Society of Radiology. PMID:25469078

[Becoming medical doctors in colonial Korea: focusing on the faculty of medical colleges in early north Korea].

Kim, Geun Bae

2014-12-01

This paper traces how Koreans of north area became medical doctors in colonial Korea. Most of the past research have focused only on the well-known medical doctors, or even when they discussed a great number of doctors, many research tended to only pay attention to the explicit final results of those doctors. This research, on the other hand, includes ordinary medical doctors as well as the renowed ones, and adjusts the focus to the lifetime period of their growth and activities. As a result, the misunderstanding and obscurity about the Korean medical doctors of north area during this period have been cleared. The new characteristics of the Korean medical doctors of this period have been found, along with their embodiment of historical significance. At the time, Koreans had to get through a number of qualifications in order to become doctors. First is the unique background of origin in which the family held interest in the modern education and was capable of supporting it financially. Second is the long-term status of education that the education from elementary to high school was completed without interruption. Third is the academic qualification that among various institutions of higher education, medical science was chosen as a major. Fourth is the condition of career in which as the career as a doctor had consistently continued. Thus, in oder to become a modern medical doctor, Koreans had to properly complete these multiple steps of process. The group of Korean medical doctors in north area, which was formed after getting through these series of process, possessed a number of characteristics. Firstly, as the upper-middle classes constituted the majority of medical doctors in Korea, the societal status of doctors rose and the foundation for the career as a doctor to be persisted as the family occupation settled. Secondly, the research career and academic degree became the principal method to escape from the discrimination and hierarchy existed between doctors. A PhD degree, especially, was the significant mark for clearly displaying the abilities and outcomes of the doctors. Lastly, the research career, education experience, clinical training and such that the Korean doctors of the period had built up were weak at the time, however, they were important sources for the future medical science development. Indeed, after Liberation, the rapid settlement and growth of Korea's medical science field were largely beholden to thus. Therefore, the growth of the Koreans as doctors did not cease in colonial Korea, but instead continued onto the history of future generations. In spite of the fact that the Korean doctors's growth and activities were greatly limited under the forceful policy of colonial domination of the era, the efforts the Korean doctors had put were not in vain. Likewise, if we do not fix our attention at the dominating policy and system, but rather put together the actors' correspondence and struggles of the period, then the Korean doctors will be a part of the living history. Hereby, the clue to the paradox between the suppression of medical science in colonial Korea and its leap after Liberation can be untied.

This study aimed to examine whether educational stressors and relational stressors are associated with burnout in medical students and to test social support as a moderator between stressors and burnout. A total of 263 medical students attending Gyeongsang National University composed the study sample. A standardized questionnaire was used to investigate educational and relational stressors, three dimensions of burnout, and social support of medical students. The findings showed that overall burnout is very high among Korean medical students, with 9.9% totally burned out. Educational and relational stressors were significantly associated with the risk of burnout in medical students after controlling for socio-demographics and health behaviors. Social support moderated educational and relational stressors on personal accomplishment, but did not moderate stressors on emotional exhaustion and depersonalization. Burnout level is substantially high among Korean medical students. Educational and relational stressors are significantly associated with burnout risk in Korean medical students. Social support had moderated educational and relational stressors on personal accomplishment. The results suggest that more social support for medical students is needed to buffer stressors on and burnout.

Historical Medical Value of Donguibogam

Oriental medicine, since its origin in China, has had a long history extending over 2000 years. Today, it comprises several types of medicine predominately practiced in East Asia, including traditional Chinese, traditional Korean, and Kampo medicine. The distinctive medical system of traditional Korean medicine was established shortly after the publication of Donguibogam by Dr. Heo Jun in 1613. Donguibogam is highly acclaimed across East Asia; in 2009, in light of its historical medical value, the United Nations Educational, Scientific, and Cultural Organization registered the book on its cultural heritage list. Here, we review the historical medical value of Donguibogam. The findings confirm that Donguibogam developed a unique and independent form of traditional Korean medicine and innovatively reformed the disease classification system. Moreover, Donguibogam emphasized the importance of disease prevention and medical pragmatism. This book also accelerated the development of folk medicine. Owing to its historical medical value, Donguibogam is now considered the 'bible' of Oriental medicine. Its wide acceptance has contributed to the expansion of Korean medicine utilization among the general public. Donguibogam has also played an important role in the establishment of traditional Korean medicine as a universally valid and original form of medicine, independent of traditional Chinese medicine.

Though traditional Korean medicine plays an important role in the Korean parallel health care system, there is limited information about the preference and usage of traditional Korean medicine compared to Western medicine because they have different disease classification systems. The aim of this study is to determine the relative preference for traditional Korean medicine using data acquired nationwide. Data from the 2008 Korea Health Panel were analyzed to determine the preference of medical services by disease. The use of traditional Korean medicine use is defined by the type of medical institution they used. Disease types, number of visits and out of pocket expenditures were analyzed. Traditional Korean medicine was used in only a small number of cases that were emergencies or hospitalization. However, in terms of outpatient services, traditional Korean medicine was used in 7.8% of all cases and represented 9.9% of total medical costs. Among disease groups, traditional Korean medicine use was higher in patients with nervous system and musculoskeletal system diseases. And patients with musculoskeletal and nervous system diseases such as arthrosis were the most likely to use traditional Korean medicine particularly in an outpatient setting. Korean characteristics of service use resemble the complementary and alternative medicine use in other countries in terms of disease group, and the complementary and alternative medicine should be considered to estimate the burden of disease in countries with parallel health care systems, such as Korea. This is the first study determined the actual preference of traditional Korean medicine for specific chronic diseases.

Until a century ago, Korean medicine was based mainly on Oriental philosophies and ideas. From a religious perspective, Chinese Confucianism was prevalent in Korea at that time. Since Confucianists believe that it is against one's filial duty to harm his or her body, given to them by their parents, most Koreans did not donate their bodies or organs for education in the past. However, by the end of the 20th century, a unique fusion of Western and Oriental medicines were produced on the Korean Peninsula, revolutionizing traditional perspectives on the human body, mortality, and the relationship of medical science to society. Koreans began to think about others' lives as well as their own by realizing the importance of donating one's organs and bodies for scientific purposes. Since then, the number of people donating their bodies to Korean medical and dental schools for the purpose of improving academic learning has increased dramatically. In response, Korean medical schools have begun to hold various types of funeral ceremonies to honor body donors. We have compared such ceremonies performed in Korea with those performed in the United States of America and Taiwan. These ceremonies are viewed as a suitable way to pay proper respect to the dead and to promote knowledge about body donation programs in Korea. Overall, the transition of religions and social ethics in Korea has greatly facilitated body bequeathal programs, benefiting both medical education and the Korean public health administration.

Driscoll, R S

2001-04-01

Medical evacuation helicopters are taken for granted in today's military. However, the first use of helicopters for this purpose in the Korean War was not done intentionally but as a result of the necessity of moving patients rapidly over difficult Korean terrain and of the early ebbing of the main battle line. The objective of this essay is to increase the historical awareness of military medical evacuation helicopters in the Korean War during this 50th anniversary year. By describing the many challenges and experiences encountered in implementing the use of helicopters for evacuation, the reader will appreciate how a technology developed for another use helped in the success of evacuating nearly 22,000 patients while contributing to establishing a mortality rate of wounded of 2.4%. The preparation to write this essay included archival research of historical reports, records, and oral histories from the archives of the U.S. Army Center for Military History. Additionally, a search of journal articles written during and after the Korean War was conducted. The result is a comprehensive description of the use of medical evacuation helicopters in the Korean War.

Framing Service, Benefit, and Credibility Through Images and Texts: A Content Analysis of Online Promotional Messages of Korean Medical Tourism Industry.

This study examines how the Korean medical tourism industry frames its service, benefit, and credibility issues through texts and images of online brochures. The results of content analysis suggest that the Korean medical tourism industry attempts to frame their medical/health services as "excellence in surgeries and cancer care" and "advanced health technology and facilities." However, the use of cost-saving appeals was limited, which can be seen as a strategy to avoid consumers' association of lower cost with lower quality services, and to stress safety and credibility.

Computerized adaptive testing (CAT) has been adopted in license examinations due to a test efficiency and accuracy. Many research about CAT have been published to prove the efficiency and accuracy of measurement. This simulation study investigated scoring method and item selection methods to implement CAT in Korean medical license examination (KMLE). This study used post-hoc (real data) simulation design. The item bank used in this study was designed with all items in a 2017 KMLE. All CAT algorithms for this study were implemented by a 'catR' package in R program. In terms of accuracy, Rasch and 2parametric logistic (PL) model performed better than 3PL model. Modal a Posteriori (MAP) or Expected a Posterior (EAP) provided more accurate estimates than MLE and WLE. Furthermore Maximum posterior weighted information (MPWI) or Minimum expected posterior variance (MEPV) performed better than other item selection methods. In terms of efficiency, Rasch model was recommended to reduce test length. Simulation study should be performed under varied test conditions before adopting a live CAT. Based on a simulation study, specific scoring and item selection methods should be predetermined before implementing a live CAT.

Medical research should be fully transparent. The aims of this study were to determine the prevalence of author-related conflict of interest (COI) policies and evaluate the actual state of COI disclosure in Korean medical journals. To determine the prevalence of author-related COI policies, we examined the 198 medical journals listed in the KoreaMed database. To investigate the actual state of COI disclosures in published papers, we analyzed the publications in a representative medical journal, the Journal of the Korean Medical Science, from the perspective of the relevance of the ethics of COI disclosure. A total of 164 (82.8%) journals required an author's statement of COI as a criterion for publication. Of these 164, most of them focused on financial COI, with 101 (61.6%) presenting the information related to COI disclosures as a separate paragraph with a clear title. We identified 114 articles published by the Journal of the Korean Medical Science over a seven-year period, from January, 2006 to December, 2012. Of these, 65 papers (57%) included an author's statement of COI. We found that the policies of Korean medical journals regarding the disclosure of author COIs are still behind the internationally suggested level. PMID:23853478

[A study on Horace N. Allen's medicine and recognition of Korean body].

PubMed

Lee, Young Ah

2011-12-31

Je Jung Won was the first modern-style Government hospital built by the Korean King Ko-Jong in April 1885, and it was the medical missionary Horace Newton Allen(1858~1932) who made one of the greatest contributions to the establishment of the hospital. Allen was an American missionary. He graduated from Ohio Wesleyan University with a degree in theology in 1881, and completed one-yearcourse at Miami Medical College. In Korea and America he worked as a physician, a missionary, an American diplomatic minister to Korea and a Korean minister's secretary to America. While acting as a mediator between Korea and America, he knew and recorded the domestic and foreign situation of Korea during Gaehwagi(the civilized and enlightened age). Thus to study him is to understand Korea's Gaehwagi as well as to research American medical missionaries. During his stay in Korea(1884~1905), Allen steadily wrote diaries and letters about Korean politics, diplomacy, society, culture, and medicine. Thus his public/private record through diaries and letters(the quantity of these materials amounts to several thousands) supplements the Korean early modern era's historical record. However, until now these materials have received little scholarly attention from researchers except for a few historians of missionary work between Korea and America, or of Korean modern medicine. I intended to use these materials to suggest a new perspective on the study of Korean Gaehwagi. Allen, along with John W. Heron, who came to Seoul on June 21st 1885, treated about 10,460 Korean patients in the first year of the opening of JeJungWon. They made "the first annual report of the Korean Government Hospital". This report explained how Allen and Heron regarded and treated Korean patients. Allen's diaries, letters and other writings offer a realistic view of how the western people actually recognized the Korean people at that time. As a western doctor, Allen had an ambivalent attitude toward Korean medical concepts and systems. On the one hand, he thought that medical idea, some food and drug of Korean is valuable. He said that the native Korea faculty had some good ideas with regards to treatment. And he held Korean rice, ginseng, and so on in high regard. However, he did not rate Korean acupuncture and Korean traditional ointment at all. In addition, he sometimes cured Korean patients dangerously and with imprudence. The amputation of patients' body, no matter how little, must ask the permission of the patients themselves. Especially, the sense of Korean filial duty couldn't accept amputation of body at those times. The artificial change of body meant to hurt parents' body, because at those times Korean people thought that my body was my parent's possession. But Allen did it without enough explanation or persuasion. Moreover he didn't feel guilty for the behavior at all. Besides, he seemed to be proud of it in the above mention. Such careless or unethical behavior cannot be excused. On the other hand, he had made mistakes in treatment according to his record. He pulled out some healthy teeth of patients who had a bad toothache. But he didn't explain nor apologize the mistake. Besides, he refused treatment of patients until the hospital would be opened in order to push Korean government to prepare hospital quickly. Why or how did he do that? The first answer available to the question, he might be so confident of his medical knowledge and skill that he didn't feel the need to ask the patients' thought and will. However, as stated above, his medical study was just one year. And he worried about his inexperience of surgery. Thus the first assumption seems to be false. He wasn't confident of his medical knowledge. The fact that nevertheless Allen treated Korean patients at his will, is still blamable. The second assumption is that he regarded western modern medicine as the only correct and proper approach. He didn't have many experiences, but his west modern medicine made him proud of its achievement. After middle 19th century of modern times, Micheal Foucault said at The Birth of Clinics, western modern medicine believed itself scientific on the ground that west modern medicine could have pathology and surgery. Allen might also trust the scientific ability of western modern medicine. So he might think that he didn't need to explain 'modern and scientific' medicine of West to people in 'premodern and non-scientific' medicine of Korea. The third answer is his 'Orientalism'. He thought that Koreans were dirty, lazy, and barbarous and, therefore, he made a clear distinction between Caucasian and Korean. He set his affection on 'Cho-Seon' and made efforts to cure Korean patients and establish the first western Government hospital in Korea. However he, as a westerner, could not free himself from 'Orientalism' and 'Imperialism'. Thus, he might ride so roughshod Korean patients. In fact the 'Orientalism' was not only Allen's thought. Many western visitors thought Korean as an 'Orient'. The West regarded themselves as civilized and the East as uncivilized or barbarous, therefore the West thought that the East should be modernized with the help of the West. This thought rationalized their imperialism and colonialism toward the East. In addition, he seemed to have some ambition in politics and diplomatics. He wanted to be a high-ranking official, so his goal of his life was political or economical power rather than medical missionary.

The purpose of the study was to examine the reliability and validity of the Adherence to Refills and Medications Scale-Korean (ARMS-K) among Korean adults with type 2 diabetes. The Korean translated ARMS-K was back-translated to ensure translation equivalency. A cross-sectional survey was used to evaluate the psychometric properties with exploratory factor analysis for validity and Cronbach's alpha coefficients for reliability. The factor analysis of construct validity identified 3 dimensions of the ARMS-K, explaining 54.7% of the total variance. The internal consistency reliability for the total instrument was acceptable with a Cronbach's alpha of .801. There was good correlation between the ARMS-K and 8-item Morisky Medication Adherence Scale-Korean version (r = -0.698), indicating that these scales measure theoretically related constructs as evidence of convergent validity. As evidence of known groups validity, there was a significant association between the ARMS-K score and glycemic control (P = .048), indicating that the good glycemic controlled group was more likely to have a higher rate of adherence to refills and medications than the poor glycemic controlled group. These results support the cross-cultural applicability of the concepts underlying the ARMS-K. The ARMS-K can be used not only to assess adherence to refills and medications in Koreans with diabetes but also to examine the potential role of adherence to refills and medications in enhanced glycemic control of people with diabetes in a variety of clinical settings. © 2016 The Author(s).

Appropriate use criteria (AUC) was developed to improve the quality of percutaneous coronary intervention (PCI). However, these criteria should consider the current practice pattern in the country where they are being applied. The algorithm for the Korean PCI practice pattern (KP3) was developed by modifying the United States-derived AUC in expert consensus meetings. KP3 class A was defined as any strategy with evidence from randomized trials that was more conservative for PCI than medical therapy or coronary artery bypass graft (CABG). Class C was defined as any strategy with less evidence from randomized trials and more aggressive for PCI than medical therapy or CABG. Class B was defined as a strategy that was partly class A and partly class C. We applied the KP3 classification system to the Korean PCI registry. The KP3 class A was noted in 67.7% of patients, class B in 28.8%, and class C in 3.5%. The median proportion of class C cases per center was 2.0%. The distribution of KP3 classes varied significantly depending on clinical and angiographic characteristics. The proportion of KP3 class C cases per center was not significantly dependent on PCI volume, but rather on the percentage of ACS cases in each center. We report the current PCI practice pattern by applying the new KP3 classification in a nationwide PCI registry. The results should be interpreted carefully with due regard for the complex relationships between the determining variables and the healthcare system in Korea.

Fatalism and health promoting behaviors in Chinese and Korean immigrants and Caucasians.

2015-02-01

Fatalism has been associated with non-adherence to health behavior in the past. This study compared fatalism of Chinese and Korean immigrants with native-born Caucasians (N = 309) and examined whether the relationship between fatalism and exercise, nutrition and medical screening would be moderated by ethnicity. Chinese reported higher fatalism than Caucasians and Koreans. Higher fatalism was associated with greater exercise among Chinese and Koreans, but less reported exercise among Caucasians. Caucasian participants had higher scores for nutrition and medical screening compared with Chinese and Korean immigrants. These findings indicate that fatalism is more prevalent among Chinese immigrants; however, there is no evidence of a detrimental effect of fatalism on exercise, nutrition or medical screening among the Asian immigrants. Caucasians with higher fatalism may be at greater risk of future illnesses, given the association between fatalism and sedentary behavior in this group. Differences between cultural groups in the adoption of health behavior justify the development and assessment of targeted interventions to optimize health promoting behaviors.

Quantifying and rating the impairments due to mental and behavior disorders are difficult for their own characteristics. Korean Academy of Medical Sciences (KAMS) is developing guidelines of rating impairment in mental and behavioral disorders based on Korean Neuropsychiatric Association (KNPA)'s new guidelines. We compared the new KNPA's guidelines and the American Medical Association (AMA)'s 6th Guides in assessing impairment due to mental and behavioral disorders to develop new guidelines of KAMS. Two guidelines are different in diagnosing system, applicable disorders, qualification of assessors, application of scales, contents of assessment and rate of impairment of the whole person. Both AMA's and the proposed guidelines have individual merits and characteristics. There is a limitation in using the 6th AMA's Guides in Korean situation. However to improve objectivity in Korean assessment of psychiatric impairment, the new AMA's Guides can serve as a good reference. PMID:19503692

Standardization of medical terminology is essential for data transmission between health-care institutions or clinical laboratories and for maximizing the benefits of information technology. Purpose of our study was to standardize the medical terms used in the clinical laboratory, such as test names, units, terms used in result descriptions, etc. During the first year of the study, we developed a standard database of concept names for laboratory terms, which covered the terms used in government health care centers, their branch offices, and primary health care units. Laboratory terms were collected from the electronic data interchange (EDI) codes from National Health Insurance Corporation (NHIC), Logical Observation Identifier Names and Codes (LOINC) database, community health centers and their branch offices, and clinical laboratories of representative university medical centers. For standard expression, we referred to the English-Korean/ Korean-English medical dictionary of Korean Medical Association and the rules for foreign language translation. Programs for mapping between LOINC DB and EDI code and for translating English to Korean were developed. A Korean standard laboratory terminology database containing six axial concept names such as components, property, time aspect, system (specimen), scale type, and method type was established for 7,508 test observations. Short names and a mapping table for EDI codes and Unified Medical Language System (UMLS) were added. Synonym tables for concept names, words used in the database, and six axial terms were prepared to make it easier to find the standard terminology with common terms used in the field of laboratory medicine. Here we report for the first time a Korean standard laboratory terminology database for test names, result description terms, result units covering most laboratory tests in primary healthcare centers.

This study constitutes a revision of the guidelines for the treatment of major depressive disorder (MDD) issued by the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) 2006. In incorporates changes in the experts׳ consensus that occurred between 2006 and 2012 as well as information regarding newly developed and recently published clinical trials. Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for (1) non-psychotic MDD, (2) psychotic MDD, (3) dysthymia and depression subtypes, (4) continuous and maintenance treatment, and (5) special populations; consensus was also obtained regarding (6) the choice of an antidepressant (AD) in the context of safety and adverse effects, and (7) non-pharmacological biological therapies. AD monotherapy was recommended as the first-line strategy for nonpsychotic depression in adults, children and adolescents, elderly adults, and patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression. The duration of the initial AD treatment for psychotic depression depends on the number of depressive episodes. Most experts recommended stopping the initial AD and AAP therapy after a certain period in patients with one or two depressive episodes. However, for those with three or more episodes, maintenance of the initial treatment was recommended for as long as possible. Monotherapy with various selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) was recommended for dysthymic disorder and melancholic type MDD. The pharmacological treatment strategy of KMAP-DD 2012 is similar to that of KMAP-DD 2006; however, the preference for the first-line use of AAPs was stronger in 2012 than in 2006.

[One hundred years history of surgery in Korea].

PubMed

Chun, S I; Yeh, B

1999-01-01

Introduction of western surgery into Korea is closely related to the introduction of western medicine itself into Korea. In December 4th, 1884 Allen, who came to Korea as a Missionary Doctor of North Presbyterian Church of America, had a chance to treat a patient with severe stab wounds. The patient was a nephew of Queen Myungsung. The patient, Min Young Ik was recovered completely. These happenings led to the establishment of 'Kwangheywon (renamed to Jejoongwon 2 weeks later)', the first westernized hospital in Korea. With the great financial aids from Severance family, Jejoongwon developed into Severance Hospital and Medical School in 1904, and greatly contributed to education of Surgery for Korean medical students. Meanwhile Korean Government established the Medical School and Hospital to train Korean Doctors in 1899. But the original intentions became to be impaired by occupation of Korea by Japan in 1910. As a colony, many Japanese Surgeons came to Korea as professors of Kyungsung Medical College, and gave only few chances for Koreans to become a professor. On the contrary, several surgeons became professors in the private, missionary 'Severance Union Medical College'. After liberation from Japanese occupation in 1945, American medical system was introduced into Korea, and many surgeons had a chance to be trained in America. There was great advancements in the field of surgery, especially of neurosurgery, during a tragic Korean War. With the restoration of economy after the 1960s, surgery in Korea continued to develop toward an independent and consolidated fields of medicine.

Interest in health information exchanges (HIEs) is increasing. Several countries have adopted core health data standards with appropriate strategies. This study was conducted to determine the feasibility of a continuity of care record (CCR) as the standard for an electronic version of the official transfer note and the HIE in Korean healthcare. A technical review of the CCR standard and analysis of stakeholders' views were undertaken. Transfer notes were reviewed and matched with CCR standard categories. The standard for the Korean coding system was selected. Stakeholder analysis included an online survey of members of the Korean Society of Medical Informatics, a public hearing to derive opinions of consumers, doctors, vendors, academic societies and policy makers about the policy process, and a focus group meeting with EMR vendors to determine which HIE objects were technically applicable. Data objects in the official transfer note form matched CCR standards. Korean Classification of Diseases, Korean Standard Terminology of Medicine, Electronic Data Interchange code (EDI code), Logical Observation Identifiers Names and Codes, and Korean drug codes (KD code) were recommended as the Korean coding standard.'Social history', 'payers', and 'encounters' were mostly marked as optional or unnecessary sections, and 'allergies', 'alerts', 'medication list', 'problems/diagnoses', 'results',and 'procedures' as mandatory. Unlike the US, 'social history' was considered optional and 'advance directives' mandatory.At the public hearing there was some objection from the Korean Medical Association to the HIE on legal grounds in termsof intellectual property and patients' personal information. Other groups showed positive or neutral responses. Focus group members divided CCR data objects into three phases based onpredicted adoption time in CCR: (i) immediate adoption; (ii) short-term adoption ('alerts', 'family history'); and (iii) long-term adoption ('results', 'advanced directives', 'functional status', 'medical equipment', 'vital signs', 'plan of care', 'social history'). There were no technical problems in generating the CCR standard document from EMRs. Matters of concern that arose from study results should be resolved with time and consultation.

This paper is a report of a comparison of advice on lifestyle given by healthcare providers and subsequent action by recipients between Korean Americans and native Koreans with hypertension. High blood pressure is controllable by having a healthy lifestyle, such as weight control, dietary change, exercise, low-sodium diet, alcohol restriction and smoking cessation, and by taking medication. Healthcare providers play an important role in teaching individuals with hypertension on healthy lifestyles. This descriptive comparative study was conducted with a convenience sample of 100 Korean Americans and 100 native Koreans with hypertension. They were interviewed between May 2003 and June 2004 on the advice they received from healthcare providers on lifestyle and their subsequent action in terms of taking medication, weight control, dietary change, exercise, low-sodium diet, smoking cessation, alcohol restriction and tension reduction. Nutrient profiles were examined using the 24-hour dietary recall method. Korean Americans received advice on lifestyle less than did native Koreans, but more Korean Americans followed healthy lifestyle advice on dietary change and exercise than did native Koreans (P<0.001). Weight control was the least adhered to behaviour among the Korean Americans, although almost two-thirds of them were overweight or obese. Both groups exceeded the Dietary Reference Intakes of sodium, but perceived their sodium consumption as low. Native Korean participants need to pay closer attention to carrying out the advice, whereas healthcare providers to Korean Americans need to give more advice on culturally acceptable healthy lifestyles, particularly on dietary changes and weight control. Both groups need to monitor their sodium intake more realistically. It is not only advice from healthcare providers that is integral to control of hypertension, but also that patients should follow that advice. © 2010 Blackwell Publishing Ltd.

Shanghanlun in Korea, 1610-1945

Suh, Soyoung

2015-01-01

This article examines how Korean physicians of traditional medicine have utilized Zhang Ji’s 張 機 (150–219 CE) Shanghanlun 傷寒論 (Treatise on Cold Damage Disorders, just Treatise hereafter) from the 17th century to the early twentieth century. As one of the two most influential pillars of Chinese medicine, the Treatise, with its clinical implications, has inspired many scholars and practitioners in their pursuit of medical innovation. What, then, have been the Korean motivations in referring to the Treatise over the past few centuries? What does the Korean utilization and modification of the Chinese classic tell us about the desires, limits, and possibilities of pursuing medical innovations in Korea? By examining the ways in which major pre-modern Korean texts employed the Treatise, this article primarily aims to reveal patterns of (re)arranging the Treatise that formed an indigenous style of medicine. Under the growing sense of nationalist concern and colonial contestation in the early twentieth century, the Korean compilation of the Treatise began to depart from the earlier interpretations. A range of nationalist rhetoric and editorial designs reflect the Korean urgency in seeking resources to compete with Western medicine. The postcolonial consumption of the Treatise also reflects Korean strategies in navigating medical references from outside to meet their social and clinical agendas. The changing pattern of textual and professional utilization of the Treatise exemplifies how a significant Chinese text continues to be a living tradition in Korea by expanding the targeted audience and satisfying local demands.

The institutionalization of pharmaceutical administration after the korean liberation: focusing on regulating the pharmaceutical affairs law(yaksabeop) in 1953.

PubMed

2013-12-01

The pharmaceutical administration under U.S Military Government in Korea and government of the Republic of Korea aimed at cleaning up the vestiges of Japanese imperialism which the pharmaceutical administration attached police administration and preparing with legal and systemic basis after the Korean liberation. The pharmaceutical bureau under U.S Military Government in Korea was reorganized as the independent division. The pharmaceutical bureau focused on preserving order, narcotics control and the distribution of relief drug. U.S Military Government proceeded supply side pharmaceutical policy for the distribution of relief drug without constructing human and material infrastructure. After the Korean War, Korean society asked the construction of system for nation building. Korean national assembly regulated National Medical Law(Gukmin uiryobeop) for promotion of public health in 1951. The Pharmaceutical Affairs Law(Yaksabeop) was regulated in 1953, and it prescribed the job requirement of pharmacist, apothecary, and drug maker and seller, and presented the frame of managing medical supplies. The Pharmaceutical Law originally planned the ideal pharmaceutical administration, but it rather secured the status of traditional apothecary, and drug maker and seller. On the contrary, though the Pharmaceutical Law guaranteed the traditional druggists, it did not materialize reproduction system such as educational and license system. It means that the traditional druggists would be degenerated in the near future. After the armistice agreement in 1953, Korean was in medical difficulties. Korean government was suffered from the deficiency of medical resources. Because of destruction of pharmaceutical facilities, Korean had to depend on United States and international aid. The Pharmaceutical Affairs Law did not cleaned up the vestiges of Japanese imperialism, and compromised with reality lacked human and material infrastructure. As a result, the law became the origin of pharmaceutical disputes such as pharmacist voluntary prescription, the separation of pharmacy and clinic, the compounding of traditional medicines, and the traditional pharmacist system. However, it was meaningful that the law was the turning point of the institutionalization of pharmaceutical administration after the Korean Liberation.

On 8 November 2013, Typhoon Haiyan made landfalls over the center of the Philippines and devastated the region. Soon aftermath of the disaster, many foreign medical teams (FMTs) headed toward the site, and the Korean team was one of them. This study described the experiences of the team during the initial phase of response, focusing on collaborative efforts with the local medical team. The Korean team was capable of providing primary care, and the Filipino team provided incomplete secondary care which was insufficient for covering the patient load. Not only did the Korean team provide electricity for hospital operation and various materials, but also supplemented medical personnel, who covered the emergency and outpatient departments. Collaborative efforts filled in each other's gap, and resulted in great synergy. Disaster medical relief mission of FMTs should be cooperated with a coordination mechanism. Collaboration with the local resources can be a great opportunity for both parties, and should not be overlooked in any disaster situations.

Identifying patients' agendas is important; however, the extent of Korean medical students' agenda-setting abilities is unknown. The study aim was to investigate the patterns of Korean medical students' agenda solicitation. A total of 94 third-year medical students participated. One scenario involving a female patient with abdominal pain was created. Students were video-recorded as they interviewed the patient. To analyze whether students identify patients' reasons for visiting, a checklist was developed based on a modified version of the Calgary-Cambridge Guide to the Medical Interview: Communication Process checklist. The duration of the patient's initial statement of concerns was measured in seconds. The total number of patient concerns expressed before interruption and the types of interruption effected by the medical students were determined. The medical students did not explore the patients' concerns and did not negotiate an agenda. Interruption of the patient's opening statement occurred in 4.62±2.20 seconds. The most common type of initial interruption was a recompleter (79.8%). Closed-ended questions were the most common question type in the second and third interruptions. Agenda setting should be emphasized in the communication skills curriculum of medical students. The Korean Clinical Skills Exam must assess medical students' ability to set an agenda.

Accurate and timely quantification of widespread harmful algal bloom (HAB) distribution is crucial to respond to the natural disaster, minimize the damage, and assess the environmental impact of the event. Although various remote sensing-based quantification approaches have been proposed for HAB since the advent of the ocean color satellite sensor, there have been no algorithms that were validated with in-situ quantitative measurements for the red tide occurring in the Korean seas. Furthermore, since the geostationary ocean color imager (GOCI) became available in June 2010, an algorithm that exploits its unprecedented observation frequency (every hour during the daytime) has been highly demanded to better track the changes in spatial distribution of red tide. This study developed a novel red tide quantification algorithm for GOCI that can estimate hourly chlorophyll-a (Chl a) concentration of Cochlodinium (Margalefidinium) polykrikoides, one of the major red tide species around Korean seas. The developed algorithm has been validated using in-situ Chl a measurements collected from a cruise campaign conducted in August 2013, when a massive C. polykrikoides bloom devastated Korean coasts. The proposed algorithm produced a high correlation (R 2 =0.92) with in-situ Chl a measurements with robust performance also for high Chl a concentration (300mg/m 3 ) in East Sea areas that typically have a relatively low total suspended particle concentration (<0.5mg/m 3 ).

Not at All Effective: Differences in Views on the Causes of Prescription Non-adherence Between North Korean Defectors and Medical Providers in South Korea.

PubMed

Hong, Soo Jung

2015-06-01

By focusing on North Korean defectors' medical experiences in South Korea and their medical providers' experiences treating the defectors, this article considers the differences between the views of these two groups in regard to the causes of prescription non-adherence. The results suggest that (a) whereas the defectors tended to see their symptoms as being physical in nature, the medical providers often ascribed symptoms to psychological/socio-cultural influence; (b) whereas the defectors tended to trust in their ability to self-diagnose and in their belief systems established in North Korea, the medical providers tended not to place trust in these aspects; (c) whereas the defectors tended to view the available medical treatment as inappropriate for them, the medical providers often noted the presence of tolerant bacterial strains as causes of treatment failure; and (d) whereas the defectors felt that the treatment they received was slow and ineffective and attributed this to capitalism, the medical providers felt that the defectors failed to understand the concept of staged treatments. Based on the findings, some solutions are suggested to address the complex issue of North Korean defectors' prescription non-adherence in terms of subjective/objective health assessments and patient-centered care. North Korean defectors' established health beliefs/lack of medical knowledge based on their previous medical and cultural experiences gave rise to beliefs and practices associated with medicine that differ significantly from those of the health providers and that have the potential to severely compromise the defectors' health. Therefore, therapy negotiation and appropriate education are suggested as possible solutions, and as an agenda, the notion of civic friendship is addressed. Implications for medical practice, prevention, and intervention are also discussed.

How four different political systems have shaped the modernization of traditional Korean medicine between 1900 and 1960.

PubMed

Dongwon, Shin

2008-03-01

In this paper, I examine the modern formation of traditional Korean medicine and discuss the characteristics of the modernization, or modernity, of the medicine. I probe for answers to three questions: first, prior to the twentieth century, what were the main factors that traditional Korean medicine needed to be transformed into a new one? Second, how did four states, the Taehan Empire, colonial Korea, North Korea, and South Korea, treat traditional medicine differently, and why? Third, what are the main characteristics of the modernization of traditional Korean medicine? In examining these questions, I found the following four factors to be important in shaping the modern formation of traditional Korean medicine during the twentieth century: first, the influences of Western science and institutions; second, the rise of nationalism; third, the economics of the state; and fourth, the effectiveness of traditional medicine. Among them, the introduction of Western science and institutions was the most important factor. All the different states in modern Korea realized that Western science and institutions were indispensable for the country to be a powerful nation and to enhance people's welfare. The degree of confidentiality in scientific Western medicine determined the number of traditional medical practitioners and their professional status. The modernization also was greatly affected by modern nationalism, which clashed with Westernization. Many Koreans and the Korean governments regarded the traditional medicine as something culturally valuable to protect from Western culture. Especially, the majority of Koreans who had experienced the cruelty of the Japanese rule under colonization tended to believe that Japan, a foreign ruler, had suppressed traditional Korean medicine as a liquidation policy of Korean culture during the colonial period. This belief contributed greatly to the recovery of the traditional doctors' prestige in South Korea and North Korea after independence. The economic conditions of the country also had an enormous effect on the quantity and quality of traditional medicine in the national medical care. Under poor economic practices, the traditional medicine never was isolated from medical care in the whole country, in spite of the pushing of the ideology of Western medicine. Particularly, since colonial Korea after the 1930s and North Korea after the 1980s were in very poor economic condition, traditional medicine played a more important role than at any other times. In South Korea, since the 1980s, has been making economic success in the course of industrialization toward an affluent society, traditional medicine is being treated as an alternative and complement to the weakness of Western medicine in the area of health improvement and treatment of chronic illness. The deep belief that traditional medicine had excellent effectiveness in this area resulted in this success. Like their ancestors, many Koreans in the twentieth century still had faith in traditional medicine. The traditional medical doctors in Korea succeeded in maintaining their own exclusive professional status, regardless of experiencing various state systems that had different attitudes toward traditional medicine. For the most part of the last one hundred years, Westernization dominated the modern formation of traditional Korean medicine. The modernization of traditional medicine, however, has been overcoming Westernization. Today active communication between Western medicine and traditional medicine is emerging. Western medical doctors, both in South and North Korea, have lessened their prejudiced views of traditional medicine and have more interest than before in the traditional medical treatments such as acupuncture.

North Korean refugee health in South Korea (NORNS) study: study design and methods

PubMed Central

2012-01-01

Background Understanding the health status of North Korean refugees (NKRs), and changes in health during the resettlement process, is important from both the humanitarian standpoint and the scientific perspective. The NOrth Korean Refugee health iN South Korea (NORNS) study aims to document the health status and health determinants of North Korean refugees, to observe various health outcomes as they occur while adapting to the westernized lifestyle of South Korea, and to explain the mechanisms of how health of migrants and refugees changes in the context of new environmental risks and opportunities. Methods The NORNS study was composed of an initial survey and a follow-up survey 3.5 years apart. Participants were recruited voluntarily among those aged 30 or more living in Seoul. The survey consists of a health questionnaire and medical examination. The health questionnaire comprises the following six domains: 1) demographic and migration information 2) disease history, 3) mental health, 4) health-related lifestyle, 5) female reproductive health, and 6) sociocultural adaptation. The medical examination comprises anthropometric measurements, blood pressure and atherosclerosis, and various biochemical measurements. Prevalence of several diseases able to be diagnosed from the medical examination, the changes between the two surveys, and the association between the outcome and other measurements, such as length of stay and extent of adaptation in South Korea will be investigated. Furthermore, the outcome will be compared to a South Korean counterpart cohort to evaluate the relative health status of NKRs. Discussion The NORNS study targeting adult NKRs in South Korea is a valuable study because various scales and medical measurements are employed for the first time. The results obtained from this study are expected to be utilized for developing a health policy for NKRs and North Korean people after unification. Additionally, since NKRs are an immigrant group who are the same race and have the same genetic characteristics as South Koreans, this study has the characteristics of a unique type of migrant health study.

This study analyzed the perceptions of medical students and faculty regarding disclosure of test items on the Korean medical licensing examination. I conducted a survey of medical students from medical colleges and professional medical schools nationwide. Responses were analyzed from 718 participants as well as 69 faculty members who participated in creating the medical licensing examination item sets. Data were analyzed using descriptive statistics and the chi-square test. It is important to maintain test quality and to keep the test items unavailable to the public. There are also concerns among students that disclosure of test items would prompt increasing difficulty of test items (48.3%). Further, few students found it desirable to disclose test items regardless of any considerations (28.5%). The professors, who had experience in designing the test items, also expressed their opposition to test item disclosure (60.9%). It is desirable not to disclose the test items of the Korean medical licensing examination to the public on the condition that students are provided with a sufficient amount of information regarding the examination. This is so that the exam can appropriately identify candidates with the required qualifications.

Depression among minority older adults is a prevalent underrecognized medical illness. Changes in cultural norms and social conditions because of immigration have a significant influence on mental health. The purpose of this study was to assess the interrelationships between acculturation, geographical location, gender, and depressive symptoms in community-dwelling elderly Korean immigrants and elderly Koreans. In this cross-sectional study, a convenience sample of 88 elderly Korean immigrants and 295 elderly Koreans was recruited separately from senior centers and senior apartments. Depressive symptoms were assessed with the Korean Geriatric Depression Scale-Short Form and acculturation with years of living in the United States. Acculturation had no significant relationship with depressive symptoms (r = 0.01, p = 0.94). Depressive symptoms were highly present in both elderly Korean immigrants and elderly Koreans. The prevalence of depressive symptoms was higher in women. This study provides baseline data for development of culturally specific, community-based intervention programs for better management of mental health of elderly Korean immigrants.

The syphilis diagnostic algorithms applied in different countries vary significantly depending on the local syphilis epidemiology and other considerations, including the expected workload, the need for automation in the laboratory and budget factors. This study was performed to investigate the efficacy of traditional and reverse syphilis diagnostic algorithms during general health checkups. In total, 1,000 blood specimens were obtained from 908 men and 92 women during their regular health checkups. Traditional screening and reverse screening were applied to the same specimens using automatic rapid plasma regain (RPR) and Treponema pallidum latex agglutination (TPLA) tests, respectively. Specimens that were reverse algorithm (TPLA) reactive, were subjected to a second treponemal test performed by using the chemiluminescent microparticle immunoassay (CMIA). Of the 1,000 specimens tested, 68 (6.8%) were reactive by reverse screening (TPLA) compared with 11 (1.1%) by traditional screening (RPR). The traditional algorithm failed to detect 48 specimens [TPLA(+)/RPR(-)/CMIA(+)]. The median TPLA cutoff index (COI) was higher in CMIA-reactive cases than in CMIA-nonreactive cases (90.5 vs 12.5 U). The reverse screening algorithm could detect the subjects with possible latent syphilis who were not detected by the traditional algorithm. Those individuals could be provided with opportunities for evaluating syphilis during their health checkups. The COI values of the initial TPLA test may be helpful in excluding false-positive TPLA test results in the reverse algorithm. © The Korean Society for Laboratory Medicine

This study aimed to compare current mental health status between North Korean defectors and South Korean natives. The proportions of depression/anxiety and the experience of suicidal ideation from 593 North Korean defectors were compared with South Koreans (n = 2372). Logistic regression analyses were conducted to determine the associated variables. As a result, the rates of depression/anxiety and suicidal ideation were significantly higher among North Korean defectors. North Koreans also had more than twice the number of escape attempts associated with high rates of depression/anxiety, and being female and single, longer durations of stay abroad, more than twice the number of escape attempts, and longer durations after entrance to South Korea were related to high rates of suicidal ideation. From these results, additional efforts are needed to identify the North Korean defectors who are at high risk for poor mental health and to provide appropriate medical services and social support.

The aim of this study was to examine the experience of violence in relation to burnout and job satisfaction in Korean nurses in the emergency medical centre setting. Participants were 236 nurses in the emergency medical centre setting of three metropolitan areas in Korea. Measures included a general characteristics form, characteristics related to experiences of violence, the Maslach Burnout Inventory and the Minnesota Satisfaction Questionnaire. Data were collected from June 2013 to February 2014. In the prediction model, 33.4% of burnout was explained and 35.7% for job satisfaction. The greatest influence on burnout was handling violence, followed by verbal abuse. The greatest influence on job satisfaction was physical threat, followed by handling violence. The study shows that burnout and job satisfaction of Korean nurses in the emergency medical centre setting are related to experiences of violence such as verbal abuse, physical threat and physical violence, as well as handling violence. © 2016 John Wiley & Sons Australia, Ltd.

Medical research during the Japanese Colonial Period became systematic and active after the Keijo Imperial University Medical School was established in 1926. Various kinds of research were conducted there including pharmacological, physiological, pathological and parasitological research. The Keijo Imperial University was give a mission to study about Korea. Urgent topics for medical research included control of infectious diseases, hygiene and environmental health that might have affected colonizing bodies of the Japanese as well as the colonized. The bodies of Koreans had been studied by Japanese even before the establishment of the University. The Keijo Imperial University research team, however, organized several field studies for physical anthropology and blood typing research at the national scale to get representative sampling of the people from its north to its south of the Korean peninsula. In the filed, they relied upon the local police and administrative power to gather reluctant women and men to measure them in a great detail. The physical anthropology and blood typing research by the Japanese researchers was related to their eagerness to place Korean people in the geography of the races in the world. Using racial index R.I.(= (A%+AB%)/(B%+AB%)), the Japanese researchers put Koreans as a race between the Mongolian and the Japanese. The preoccupation with constitution and race also pervasively affected the medical practice: race (Japanese, Korean, or Japanese living in Korea) must be written in every kind of medical chart as a default. After the breakout of Chinese-Japanese War in 1937, the Keijo Imperial University researchers extended its physical anthropology field study to Manchuria and China to get data on physics of the people in 1940. The Japanese government and research foundations financially well supported the Keijo Imperial University researchers and the field studies for physical anthropology in Korea, Manchuria and China. The physical anthropology research was actively conducted hand in hand with imperialistic expansion, and driven by zeal for measuring the body.

This study aimed to compare the usage of Western medicine and traditional Korean medicine for treating joint disorders in Korea. Data of claims from all medical institutions with billing statements filed to HIRA from 2011 to 2014 for the four most frequent joint disorders were used for the analysis. Data from a total of 1,100,018 patients who received medical services from 2011 to 2014 were analyzed. Descriptive statistics are presented as type of care and hospital type. All statistical analyses were performed using IBM SPSS for Windows version 21. Of the 1,100,018 patients with joint disorders, 456,642 (41.5%) were males and 643,376 (58.5%) were females. Per diem costs of hospitalization in Western medicine clinics and traditional Korean medicine clinics were approximately 160,000 KRW and 50,000 KRW, respectively. Among costs associated with Western medicine, physiotherapy cost had the largest proportion (28.78%). Among costs associated with traditional Korean medicine, procedural costs and treatment accounted for more than 70%, followed by doctors' fees (21.54%). There were distinct differences in patterns of medical care use and cost of joint disorders at the national level in Korea. This study is expected to contribute to management decisions for musculoskeletal disease involving joint disorders. PMID:29456569

Studies of East Asian medical history in Korea have progressively accumulated in the last twenty years. First, Korean scholars broadened the focus of research from China-centered research to East Asian research. Studies of Toyo medical history in Korea mainly concentrated on Chinese medical history. Toyo medical history originated from Japanese orientalism and imperialism. Today the studies of East Asian medical history in Korea include Korea, China and Japan, and attempt to deal with East Asia as a single conceptual category. Second, researchers in East Asian medical history are steadily increasing. They study Chinese medical history or Japanese medical history from universities. As they continue their research in academic positions, successive researchers emerge. Third, the number of Korean scholars remains relatively small, but they pursue original research. Their interests are in the discourse of East Asian medical history, colonial modernity, environmental history, oral history, and history of disease.

In 2017, the Korean Diabetes Association (KDA) published a position statement on the use of antihyperglycemic agents for patients with type 2 diabetes mellitus (T2DM). The KDA regularly updates its Clinical Practice Guidelines, but since the last update in 2015, many results from clinical trials have been introduced, and domestic data from studies performed in Korean patients with T2DM have been published. Recently, evidence from large clinical studies assessing cardiovascular outcomes following the use of sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists in patients with T2DM were incorporated into the recommendations. Additionally, new data from clinical trials using dipeptidyl peptidase 4 inhibitors and thiazolidinediones in Korean patients with T2DM were added. Following a systematic review and assessment of recent evidence, the KDA updated and modified its clinical practice recommendations regarding the use of antihyperglycemic agents and revised the treatment algorithm for Korean adult patients with T2DM.

The Korean Diabetes Association (KDA) has regularly updated its Clinical Practice Guidelines. In 2017, the KDA published a position statement on the use of antihyperglycemic agents for patients with type 2 diabetes mellitus (T2DM). Growing evidence from new multinational clinical trials using novel and traditional insulin analogues has also been accumulated. Following global trends, many results of clinical trials, especially concerning the clinical efficacy and safety of insulin therapy, have been published about Korean patients with T2DM. After a systematic search of recent evidence, the KDA updated and modified its clinical practice recommendations regarding the initiation, choice, and intensification of insulin and created an insulin treatment algorithm for the first time to guide physicians caring for adult Korean patients with T2DM.

Through implementation of its 2000 pharmaceutical reform, the South Korean government expected to reduce the cost of medications and improve service levels, medical appropriateness of care, and drug effectiveness. However, despite the reform's lofty goals, unintended consequences have distorted the supply of medical services and spending. These consequences have included increasing the use of uninsured services, prescribing high-price drugs, and a growing market share for multinational drug companies. Further reforms are needed to reduce the measure's adverse effects. This paper examines the Korean mandatory prescription system and offers an analysis of Korea's reforms.

[Building Process and Architectural Planning Characteristics of Daehan Hospital Main Building].

PubMed

Lee, Geauchul

2016-04-01

This paper explores the introduction process of Daehan Hospital from Japan as the modern medical facility in Korea, and the architectural planning characteristics as a medical facility through the detailed building process of Daehan Hospital main building. The most noticeable characteristic of Daehan Hospital is that it was designed and constructed not by Korean engineers but by Japanese engineers. Therefore, Daehan Hospital was influenced by Japanese early modern medical facility, and Japanese engineers modeled Daehan Hospital main building on Tokyo Medical School main building which was constructed in 1876 as the first national medical school and hospital. The architectural type of Tokyo Medical School main building was a typical school architecture in early Japanese modern period which had a middle corridor and a pseudo Western-style tower, but Tokyo Medical School main building became the model of a medical facility as the symbol of the medical department in Tokyo Imperial University. This was the introduction and transplantation process of Japanese modern 'model' like as other modern systems and technologies during the Korean modern transition period. However, unlike Tokyo Medical School main building, Daehan Hospital main building was constructed not as a wooden building but as a masonry building. Comparing with the function of Daehan Hospital main building, its architectural form and construction costs was excessive scale, which was because Japanese Resident-General of Korea had the intention of ostentation that Japanese modernity was superior to Korean Empire.

Survey of controversial issues of end-of-life treatment decisions in Korea: similarities and discrepancies between healthcare professionals and the general public

PubMed Central

2013-01-01

Introduction End-of-life (EOL) treatment issues have recently gained societal attention after the Korean Supreme Court’s ruling that the presumed wishes of an elderly woman in a persistent vegetative state (PVS) should be honored. We tried to evaluate what Koreans thought about controversial issues regarding EOL treatments. Methods We surveyed Koreans with the following questions: 1) are ventilator-dependent PVS patients candidates for end-of life treatment decisions? 2) Is withholding and withdrawing EOL treatment the same thing? 3) In an unconscious, terminally ill patient, whose wishes are unknown, how should EOL decisions be made? 4) How should we settle disagreement amongst medical staff and the patient’s family on EOL decisions? Results One thousand Koreans not working in healthcare and five hundred healthcare professionals responded to the survey. Fifty-seven percent of Koreans not working in healthcare and sixty seven percent of Korean healthcare professionals agreed that ventilator-dependent PVS patients are candidates for EOL treatment decisions. One quarter of all respondents regarded withholding and withdrawing EOL treatment as equal. Over 50% thought that EOL treatment decisions should be made through discussions between the physician and the patient’s family. For conflict resolution, 75% of Koreans not working in healthcare preferred direct settlement between the medical staff and the patient’s family while 55% of healthcare professionals preferred the hospital ethics committee. Conclusions Unsettled issues in Korea regarding EOL treatment decision include whether to include ventilator-dependent PVS patients as candidates of EOL treatment decision and how to sort out disagreements regarding EOL treatment decisions. Koreans viewed withholding and withdrawing EOL treatment issues differently. PMID:24093519

This study aimed at characterizing Korean nurses' occupational responsibilities to apply the results for improvement of the Korean Nursing Licensing Examination. First, the contents of nursing job were defined based on a focus group interview of 15 nurses. Developing a Curriculum (DACOM) method was used to examine those results and produce the questionnaire by 13 experts. After that, the questionnaire survey to 5,065 hospital nurses was done. The occupational responsibilities of nurses were characterized as involving 8 duties, 49 tasks, and 303 task elements. Those 8 duties are nursing management and professional development, safety and infection control, the management of potential risk factors, basic nursing and caring, the maintenance of physiological integrity, medication and parenteral treatments, socio-psychological integrity, and the maintenance and improvement of health. The content of Korean Nursing Licensing Examination should be improved based on 8 duties and 49 tasks of the occupational responsibilities of Korean nurses.

A persistent challenge to self-report data across racial, ethnic, or cultural groups is the inherent difficulty of attaining cross-cultural comparability of key measures. The current research study investigated the cross-cultural functioning of health-survey questions presented to four groups: (1) Koreans who were monolingual in Korean; (2) non-Korean native speakers of English; (3) bilingual Koreans interviewed in English, and (4) bilingual Koreans interviewed in Korean. This design allowed us to include those likely to be medically underserved, and to assess both linguistic and cultural barriers to collecting health survey data. A total of 36 cognitive interviews were conducted to identify (a) translation problems; (b) problems of cultural adaptation that impede cross-cultural comparability; and (c) generic problems of questionnaire design that affect all groups. An important category of problems was identified that appeared to result from the interaction of respondent and question characteristics. Such problems can best be assessed through explicit consideration of the socio-cultural backgrounds of survey respondents, as opposed to the more usual focus on details of item translation and wording.

[Missionary Medicine of Canadian Presbytery and Korean Doctors under Japanese Occupation--focusing Sung-jin and Ham-heung].

PubMed

Heo, Yun-Jung; Cho, Young-Soo

2015-12-01

In East Asia during the second half of the 19th century, overseas mission work by Protestant churches thrived. Missionaries built schools and hospitals and effectively used them for evangelism. In the 20th century when Social Gospel Movement was expanding, medical work has been recognized as a significant mission service in and by itself. This article reviewed the construction and characteristics of missions work conducted by Canadian Presbytery; missionary doctors and Korean doctors who worked at the mission hospitals; why the missionary medical work had to stop; and career paths taken by Korean doctors upon liberation from Japanese occupation. The Canadian Presbytery missionaries, unlike other denomination missionaries, were rather critical of Imperial Japan, but supportive towards Koreans. This could have stemmed from the reflection of their own experience of once a colony of British Empire and also their value system that promotes egalitarian, democratic and progressive theology. The Sung-jin and Ham-heung Mission Bases were a community, interacting organically as a 'Triangle of Church, School and Hospital.' The missionaries mobilized the graduates from Christian schools and organized a Young Men's Christian Association (YMCA). Some of the graduates were trained to become medical doctors or assistants and worked at mission hospitals. Missionary doctors' approaches to balancing evangelism and medical practice varied. For example, Robert Grieson went through confusion and struggled to balance conflicting roles as a pastor for evangelism and also as a physician. Kate McMillan, on the other hand, had less burden for evangelism than Grieson, and focused on medical work by taking advantage of the opportunity that, as a woman, she can easily approach Korean women. Still another case was Florence Murray who practised evangelism within the hospital setting, and successfully carried out the role as a hospital administrator, going beyond 'women's work' as McMillan did. Korean doctors and assistants who worked at the mission hospitals had seen the spread of Protestantism in their youth; had received modern education; had experienced the fall of own country in 1910 and nationwide protest against Japan in 1919. The majority of them were graduates of Severance Medical College, the hub of missionary medicine at the time. After the resignation from the mission hospitals, 80 percent of them became self-employed general practitioners. The operations of the mission hospitals began to contract in 1930 due to tightened control by Imperial Japan. Shrine worship imposed on Christians caused internal conflict and division among missionaries and brought about changes in the form and contents of the mission organization. The incidence of the assault of Dr. Grieson brought about the dissolution of Sung-jin mission base and the interruption of the operation of Je-dong Hospital. As the Pacific War expanded, missionaries were driven out of Korea and returned home. In conclusion, the missions work by Canadian Presbytery missionaries had greatly impacted Protestantism in Korea. The characteristics of Canadian Presbytery were manifested in their support of Korean nationalism movement, openness for Social Gospel, and maintaining equal footing with Korean Christians. Specifically we note the influence of these characteristics in Chosun doctors who had worked in the mission hospitals. They operated their own hospitals or clinics in a manner similar to the mission hospitals by providing treatment for poor patients free of charge or for a nominal fee and treating the patients in a kind and humanistic way. After the 1945 Liberation, Korean doctors'career paths split into two directions. most of them defected to South Korea and chose the path to work as general practitioners. A few of them remained in North Korea and became educator of new doctors. It is meaningful that former doctors of Canadian missionary hosptal became dean of 2 medical colleges among 3 of all in early North Korea. This article does not cover the comparative analysis of the medical work by the missionaries of Canadian Presbytery and other denominations. It is desirable to include this analysis of the contents and the comparison in a future study of Korean doctors who participated in the mission hospitals, by denomination and by geographical region.

The aim of this research is to propose an alarm index to forecast the crash of the Korean financial market in extension to the idea of Johansen-Ledoit-Sornette model, which uses the log-periodic functions and pattern recognition algorithm. We discover that the crashes of the Korean financial market can be classified into domestic and global crises where each category requires different window length of fitted datasets. Therefore, we add the window length as a new parameter to enhance the performance of alarm index. Distinguishing the domestic and global crises separately, our alarm index demonstrates more robust forecasting than previous model by showing the error diagram and the results of trading performance.

[Medical ethics as professional ethics].

PubMed

Kwon, Ivo

2012-09-25

Contemporary medical ethics is far from the traditional concept of "In-Sul (benevolent art)" or "Yul-Li (倫, ethics), which emphasizes so much the personality or the character of a doctor. Nowadays, medical ethics should be considered as "professional ethics" which regulates the acts and medical practices of ordinary doctors in their daily practice. The key concepts of the professional ethics are "autonomy", "integrity", and "professional standard" established by medical organizations such as medical societies or associations. Most of Korean doctors have not been familiar with the concept of professional ethics or professionalism, which is due to the modern history of Korea. However, the concept of professional ethics is really critical to Korean doctors from the perspective of professional dignity and social respect to this profession. The current healthcare system of Korea is suffering from many problems of both private and public sector. Nonetheless, the professional ethics is urgently demanded for that very reason.

Abstract Objective To investigate adverse events attributed to traditional medical treatments in the Republic of Korea. Methods Adverse events recorded in the Republic of Korea between 1999 and 2010 – by the Food and Drug Administration, the Consumer Agency or the Association of Traditional Korean Medicine – were reviewed. Records of adverse events attributed to the use of traditional medical practices, including reports of medicinal accidents and consumers’ complaints, were investigated. Findings Overall, 9624 records of adverse events attributed to traditional medical practices – including 522 linked to herbal treatments – were identified. Liver problems were the most frequently reported adverse events. Only eight of the adverse events were recorded by the pharmacovigilance system run by the Food and Drug Administration. Of the 9624 events, 1389 – mostly infections, cases of pneumothorax and burns – were linked to physical therapy (n = 285) or acupuncture/moxibustion (n = 1104). Conclusion In the Republic of Korea, traditional medical practices often appear to have adverse effects, yet almost all of the adverse events attributed to such practices between 1999 and 2010 were missed by the national pharmacovigilance system. The Consumer Agency and the Association of Traditional Korean Medicine should be included in the national pharmacovigilance system. PMID:23940404

Two new Korean laws regulating animal welfare and the humane use of animals in science came into effect in 2008 and 2009. Both these laws impose ethical committee review prior to the performance of animal experiments in research, testing and education. This study briefly summarises the new Korean laws, and investigates the current status regarding the numbers of animals used, the alternatives to animals which are used, the curricula relating to the humane use of animals, and ethical review practices in Korean veterinary education. Approximately 4,845 animals, representing 20 different species, were used in veterinary medical education in Korea in 2007. Korea has begun to introduce formal courses on animal welfare for the humane treatment of animals used in experiments, and an ethical protocol review system prior to animal use in education. Korea is moving toward better animal welfare, by incorporating practices consistent with international standards. The information presented represents the first such data gathered in Korea, which should prove useful for monitoring the implementation of replacement, reduction, and refinement measures in animal use for education purposes.

This study aimed to investigate medical records using traditional Korean medicine (TKM) in Sewol Ferry disaster in 2014 and further explore the possible role of traditional medicine in disaster situation. After Sewol Ferry accident, 3 on-site tents for TKM assistance by the Association of Korean Medicine (AKOM) in Jindo area were installed. The AKOM mobilized volunteer TKM doctors and assistants and dispatched each on-site tent in three shifts within 24 hours. Anyone could use on-site tent without restriction and TKM treatments including herb medicine were administered individually. The total of 1,860 patients were treated during the periods except for medical assistance on the barge. Most patients were diagnosed in musculoskeletal diseases (66.4%) and respiratory diseases (7.4%) and circulatory diseases (8.4%) followed. The most frequently used herbal medicines were Shuanghe decoction (80 days), Su He Xiang Wan (288 pills), and Wuji powder (73 days). TKM in medical assistance can be helpful to rescue worker or group life people in open shelter when national disasters occur. Therefore, it is important to construct a rapid respond system using TKM resources based on experience.

Acute otitis media (AOM) and otitis media with effusion (OME) are common infections in children, and their diagnosis and treatment have significant impacts on the health of children and the costs of providing national medical care. In 2009, the Korean Otologic Society organized a committee composed of experts in the field of otolaryngology, pediatrics, and family medicine to develop Korean clinical practice guidelines (CPG) for otitis media in children with the goal of meeting regional medical and social needs in Korea. For this purpose, the committee adapted existing guidelines. A comprehensive literature review was carried out primarily from 2004 to 2009 using medical search engines including data from Korea. A draft was written after a national questionnaire survey and several public audits, and it was editorially supervised by senior advisors before publication of the final report. These evidence-based guidelines for the management of otitis media in children provide recommendations to primary practitioners for the diagnosis and treatment of children younger than 15 yr old with uncomplicated AOM and OME. The guidelines include recommendations regarding diagnosis, treatment options, prevention and parent education, medical records, referral, and complementary/alternative medicine for treating pediatric otitis media.

The Korean Journal of Urology began to be published exclusively in English in 2010 and is indexed in PubMed Central/PubMed. This study analyzed a variety of citation indicators of the Korean Journal of Urology before and after 2010 to clarify the present position of the journal among the urology category journals. The impact factor, SCImago Journal Rank (SJR), impact index, Z-impact factor (ZIF, impact factor excluding self-citation), and Hirsch Index (H-index) were referenced or calculated from Web of Science, Scopus, SCImago Journal & Country Ranking, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, and Google Scholar. Both the impact factor and the total citations rose rapidly beginning in 2011. The 2012 impact factor corresponded to the upper 84.9% in the nephrology-urology category, whereas the 2011 SJR was in the upper 58.5%. The ZIF in KoMCI was one fifth of the impact factor because there are only two other urology journals in KoMCI. Up to 2009, more than half of the citations in the Web of Science were from Korean researchers, but from 2010 to 2012, more than 85% of the citations were from international researchers. The H-indexes from Web of Science, Scopus, KoMCI, KoreaMed Synapse, and Google Scholar were 8, 10, 12, 9, and 18, respectively. The strategy of the language change in 2010 was successful from the perspective of citation indicators. The values of the citation indicators will continue to increase rapidly and consistently as the research achievement of authors of the Korean Journal of Urology increases. PMID:23614057

2016-11-01

This paper examines first-generation Korean immigrants' barriers to healthcare in the US and their strategies for coping with these issues by analyzing survey data from 507 Korean immigrants and in-depth interviews with 120 Korean immigrants in the New York-New Jersey area. It reports that more than half of Korean immigrants have barriers to healthcare in the US, with the language barrier being the most frequent response, followed by having no health insurance. Korean immigrants are not passive, but rather active entities who display coping strategies for these barriers, such as seeing co-ethnic doctors in the US, seeking Hanbang (traditional Korean medicine) in the US, and taking medical tours to the home country. However, their coping strategies are far removed from formal US healthcare as their behaviors are still restricted to the informal healthcare within the ethnic community or home country. This study methodologically and theoretically contributes to the literature on immigrants' healthcare behaviors by using a mixed-method approach and developing a specific framework for one particular immigrant group.

Shin, Young-Jeon

2006-12-01

Woosaeng, meaning "eugenic" in Korean, was a bulletin published by the Korean Eugenics Association in 1934. With detailed review of the contributors to Woosaeng, its publication background and the contents, the characteristics of Korea's eugenic movement in 1930's and its historical implications of public health are studied. Intellectuals, especially some medical doctors educated abroad, played the pivotal role in publishing Woosaeng and leading the eugenic movement in 1930's. Lee Gabsoo, a medical doctor educated in Germany, is identified as the key person in the whole process. Most of contributors including Lee considered medical science, especially genetics, as the foundation of eugenics and had strong confidence in their belief. A variety of eugenic movements and activities, including enactment of the national eugenic law around the world. was introduced to the Korean society through Woosaeng and it reinforced the eugenic activities in Korea. Although colonial Korea at the time was being heavily imposed with Japan's culture, the eugenic activities were also influenced by Germany and the US through the contributors educated oversea. The overall content and tone of Woosaeng, revealed its 'soft' characteristics, yet it also implied its vulnerability to 'hard' eugenics. Korea's eugenic movement around Woosaeng faces turnover right before 'The Go Fast Imperialism' period. The high class intellectuals tamed by Japanese colonial paradigm in eugenics took the lead and ended up having a significant influence upon the activities around Woosaeng. And even after Koreans' liberation from Japan's annexation, they were able to retain their influence in public health area in the Korean society. In summary, Woosaeng guided us to understand the characteristics of Korea's eugenic movement in 1930's and the historical context of public health in Korea. Moreover, Woosaeng provided a large amount of information about the eugenic movements around the world as well as in Korea. It also provided some specific examples about the strategic relationship between medical science and politics in 1930's Korea.

2000-06-01

Cervical cancer is a significant health problem for Korean-American women. It currently is the number one female cancer diagnosed among women in South Korea. Despite this fact, Korean-American women have very low rates of cervical cancer screening. The purpose of this research were to gain an understanding of Korean women's knowledge about cervical cancer, and to identify major barriers to early screening for cervical cancer and the motivators for prevention and early detection. It is hoped that the findings will guide the development of community-based cervical cancer education and screening programs for adult Korean-American women. The health belief model (HBM) provided the theoretical basis for the study. A qualitative study with eight focus groups (n = 102) was conducted using 11 questions derived from the HBM. Focus group discussions revealed that there was misinformation and a lack of knowledge about cervical cancer. The women therefore were confused about the causative factors and preventive strategies related to cervical cancer. The findings showed that major structural barriers were economic and time factors along with language problems. Many participants were recent immigrants with no medical insurance and long work hours. The main psychosocial barriers were fear/fatalism, denial, and Confucian thinking. Participants stated that medical advice and education would influence them most to undergo a Pap test. Recommendations were made to reduce certain barriers and to increase knowledge and motivations.

The major objectives of this study were to provide a list of candidate antiaging medicinal herbs that have been widely utilized in Korean medicine and to organize preliminary data for the benefit of experimental and clinical researchers to develop new drug therapies by analyzing previous studies. “Dongeuibogam,” a representative source of the Korean medicine literature, was selected to investigate candidate antiaging medicinal herbs and to identify appropriate terms that describe the specific antiaging effects that these herbs are predicted to elicit. In addition, we aimed to review previous studies that referenced the selected candidate antiaging medicinal herbs. From our chosen source, “Dongeuibogam,” we were able to screen 102 terms describing antiaging effects, which were further classified into 11 subtypes. Ninety-seven candidate antiaging medicinal herbs were selected using the criterion that their antiaging effects were described using the same terms as those employed in “Dongeuibogam.” These candidates were classified into 11 subtypes. Of the 97 candidate antiaging medicinal herbs selected, 47 are widely used by Korean medical doctors in Korea and were selected for further analysis of their antiaging effects. Overall, we found an average of 7.7 previous studies per candidate herb that described their antiaging effects. PMID:25861371

The purpose of this study was to categorize surgery-related medical terminologies used in South and North Korea and to compare and analyze discrepancies observed in the terms. This study collected medical terminology used in the North Korean medical book "Surgery" and compared it to medical terminology found in the medical glossary of South Korea. The order of the subtitle was described according to the Instruction to Authors. In total, there were 2,168 individual medical terms, of which only 1,004 words (46.3%) were identical to South Korean medical terms. There were 581 similar terms (26.8%), 265 different terms (12.2%), and 318 terms that are nonexistent in South Korea (14.7%). Less than half of the medical terms used in North Korea match those used in South Korea. It is expected that the prolongation of the current division of South and North Korea will only worsen this discrepancy. Further efforts to bridge the gap through academic exchange between South Korea and North Korea are required in preparation for an era of reunification.

There were 581 similar terms (26.8%), 265 different terms (12.2%), and 318 terms that are nonexistent in South Korea (14.7%). Conclusion Less than half of the medical terms used in North Korea match those used in South Korea. It is expected that the prolongation of the current division of South and North Korea will only worsen this discrepancy. Further efforts to bridge the gap through academic exchange between South Korea and North Korea are required in preparation for an era of reunification. PMID:29510608

This aim of this study is to examine trends in medical education research in the Korean Journal of Medical Education(KJME) and suggest improvements for medical education research. The main variables were keywords from research papers that were published in KJME. Abstracts of papers (n=499) that were published from 1991 through 2015 were analyzed by social network analysis (NetMiner 4.0) a common research methodfor trends in academic subjects. The most central keywords were "medical education," "clinical competence," "medical student," and "curriculum." After introduction into graduate medical school, newly appearing keywords were "professional behavior," "medical humanities," "communication,"and "physician-patient relation." Based on these results, we generated a schematic of the network, in which the five groups before introduction to graduate medical school expanded to nine groups after introduction. Medical education research has been improving qualitatively and quantitatively, and research subjects have been expanded, subdivided, and specific. While KJME has encompassed medical education studies comprehensively, studies on medical students have risen in number. Thus, the studies that are published in KJME were consistent with the direction of journal and a new study on the changes in medical education is being conducted.

Retrospective optimal interpolation (ROI) is a method that is used to minimize cost functions with multiple minima without using adjoint models. Song and Lim (2011) perform the experiments to reduce the computational costs for implementing ROI by transforming the control variables into eigenvectors of background error covariance. We adapt the ROI algorithm to compute sensitivity estimates of severe weather events over the Korean peninsula. The eigenvectors of the ROI algorithm is modified every time the observations are assimilated. This implies that the modified eigenvectors shows the error distribution of control variables which are updated by assimilating observations. So, We can estimate the effects of the specific observations. In order to verify the adaptive observation strategy, High-impact weather over the Korean peninsula is simulated and interpreted using WRF modeling system and sensitive regions for each high-impact weather is calculated. The effects of assimilation for each observation type is discussed.

The military medical system of the Korean People's Army (KPA) first appeared in August 1946 when a central military hospita was established at the headquarters. Inside the KPA, the military medical and veteran services were first established in February 1948. The military medical officers of the KPA were those who were initially engaged in North Korea's health care sector. Most of the early military medical officers were those who had been trained in the Japanese medical system before liberation and were surgeons. After the establishment of the government in September 1948, Lee Dongwha rapidly introduced the medical system of the Soviet army into the KPA. The KPA military medical system was a mix of Soviet, Japanese and Chinese military medical systems. The medical section of the KPA was similar to that of the Japanese army, and the medical section of the lower army was similar to that of the Soviet army. The stretcher platoon of the KPA were similar to those of the Japanese and Chinese armies. The KPA mainly used Japanese medical equipment at the beginning, and after the establishment of the North Korean regime in September 1948, they were gradually replaced with Soviet products. The military medical office of the KPA were equipped with treatment rooms, laboratories, hospitals, pharmacy, and inpatient rooms. The military medical office purchased medical journals and specimens for medical research and set up a separate research fund. In addition, the military medical office was equipped with a laboratory for medical experiments and raised laboratory animals. The KPA military medical system was specialized in the fields of infectious disease prevention and preventive medicine. At the time, infectious disease in North Korea was mainly caused by bacteria and viruses in unsanitary living environments. The KPA set up a special anti-infectious disease department in consideration of the soldiers living in the collective facilities. The second characteristic of the KPA military medical system is preventive medicine. Since early 1946, North Korea has been interested in preventive medicine and has established various medical facilities and personnel. In line with this history of preventive medicine, the preventive department was installed in the KPA military medical system.

Korea's National Healthcare Program, the National Health Insurance Service (NHIS), a government-affiliated agency under the Korean Ministry of Health and Welfare, covers the entire Korean population. The NHIS supervises all medical services in Korea and establishes a systematic National Health Information database (DB). A health information DB system including all of the claims, medications, death information, and health check-ups, both in the general population and in patients with various diseases, is not common worldwide. On June 9, 2014, the NHIS signed a memorandum of understanding with the Korean Diabetes Association (KDA) to provide limited open access to its DB. By October 31, 2017, seven papers had been published through this collaborative research project. These studies were conducted to investigate the past and current status of type 2 diabetes mellitus and its complications and management in Korea. This review is a brief summary of the collaborative projects between the KDA and the NHIS over the last 3 years. According to the analysis, the national health check-up DB or claim DB were used, and the age category or study period were differentially applied. Copyright © 2018 Korean Diabetes Association.

[The translation and its meanings of Materia Medica Part. I in the Jejungwon].

PubMed

Park, Junhyoung; Park, Hyoungwoo

2011-12-31

For more systematic medical education, Dr. O. R. Avison translated medical textbooks into Korean since he took charge of Jejungwon in 1893. The first book he chose was Anatomy of the Human Body. He, however, failed to see it published after losing its manuscript twice. Instead, Materia Medica Part. I was brought into the world first in 1905, for which he translated Materia Medica and Therapeutics written by John Mitchell Bruce from the U. K. At that time, this book was in widespread use in the English-speaking world as a textbook for pharmacology. It is also assumed that Avison used it as a textbook for his classes in Canada before coming to Korea. For the publication of Materia Medica Part. I, Avison did not translate Bruce's original text in full, but translated only the selected passages. He followed a principle of using Korean alphabets (Hangeul) only, but in combination with Chinese characters, if necessary. He put pharmacological terms into existing Korean equivalents or newly coined words, but also borrowed many from Japanese terms. That's because Japan moved faster to introduce Western medicine than Korea did, so that many pharmacological terms could be defined and arranged more systematically in Japanese. Moreover, Japan took such a favorable stance in the state of international affairs that many of Japanese-style terms could be introduced into Korea in most fields including medicine. By translating Materia Medica Part. I in cooperation with his disciple KIM Pilsoon after Gray's Anatomy of the Human Body, Avison tried to lay groundwork for providing medical education in Korea based on the British-American medicine. It is assumed that he took an independent stance in selecting and translating Western medical textbooks on his own rather than simply accepting the existing Chinese translation of Western medical textbooks. Despite all his efforts, he might find it difficult to translate all the Western medical terms into Korean within a short period of time. Therefore, he seems to have had no choice but to accept Japanese medical terms as a complementary measure.

Ethnomedicine and dominant medicine in multicultural Australia: a critical realist reflection on the case of Korean-Australian immigrants in Sydney

Background Viewed through the micro focus of an interpretive lens, medical anthropology remains mystified because interpretivist explanations seriously downplay the given context in which individual health seeking-behaviours occur. This paper draws upon both the interpretivist and political economy perspectives to reflect on the ethno medical practices within the Korean-Australian community in Sydney. Methods We draw on research data collected between 1995 and 1997 for an earlier study of the use of biomedical and traditional medicine by Korean-Australians in Sydney. A total of 120 interviews were conducted with a range of participants, including biomedical doctors, traditional health professionals, Korean community leaders and Korean migrants representing a range of socio-economic backgrounds and migration patterns. Results and Discussion First, the paper highlights the extent to which the social location of migrants in a host society alters or restructures their initial cultural practices they bring with them. Second, taking hanbang medicine in the Korean-Australian community as an illustrative case, the paper explores the transformation of the dominant biomedicine in Australia as a result of the influx of ethnomedicine in the era of global capitalism and global movement. Conclusion In seeking to explain the popularity and supply of alternative health care, it is important to go beyond the culture of each kind of health care itself and to take into consideration the changes occurring at societal, national and global levels as well as consequential individual response to the changes. New social conditions influence the choice of health care methods, including herbal/alternative medicine, health foods and what are often called New Age therapies. PMID:17201916

This study focuses on the formation of medical education in North Korea from 1945 to 1948 in terms of the centralization of medical education, and on the process and significance of the systemization of medical education. Doctors of the past trained under the Japanese colonial system lived and worked as liberalists. More than half of these doctors who were in North Korea defected to South Korea after the country was liberated. Thus the North Korean regime faced the urgent task of cultivating new doctors who would 'serve the state and people.' Since the autumn of 1945, right after national liberation, Local People's Committees organized and implemented medical education autonomously. Following the establishment of the Provisional People's Committee of North Korea, democratic reform was launched, leading to the centralized administration of education. Consequently, medical educational institutions were realigned, with some elevated to medical colleges and others shut down. The North Korean state criticised the liberalistic attitude of doctors and the bureaucratic style of health administration, and tried to reform their political consciousness through political inculcation programs. The state also grant doctors living and housing privileges, which show its endeavor to build 'state medicine'. By 1947, a medical education system was established in which the education administration was put in charge of training new doctors while the health administration was put in charge of nurturing and retraining health workers. In this way, the state was the principal agent that actively established a centralized administrative system in the process of the formation of medical education in North Korea following national liberation. Another agent was deeply involved in this process - the faculty that was directly in charge of educating the new doctors. Studying the medical faculty remains another research task for the future. By exploring how the knowledge, generational experience, socio-political consciousness and world views adopted by these teachers during the colonial era were manifested in their pedagogy after national liberation will shed more light on the 'prototype' of North Korean medical education.

Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE). Thus, this review will aim to evaluate the current evidence on the efficacy of integrative medicine for the management of lupus nephritis in patients with SLE. The following electronic databases will be searched for studies published from their dates of inception February 2018: Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as 6 Korean medical databases (Korea Med, the Oriental Medicine Advanced Search Integrated System [OASIS], DBpia, the Korean Medical Database [KM base], the Research Information Service System [RISS], and the Korean Studies Information Services System [KISS]), and 1 Chinese medical database (the China National Knowledge Infrastructure [CNKI]). Study selection, data extraction, and assessment will be performed independently by 2 researchers. The risk of bias (ROB) will be assessed using the Cochrane ROB tool. This systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy.

Kim, Yoon Hee

2012-01-01

In May 2011, the Ministry of Unification of the Republic of Korea (Korea) announced that 21,165 defectors from Democratic People's Republic of Korea (North Korea) had settled in Korea. Since healthcare workers are counted among these defectors, it is necessary to provide them with a pathway to certification to work in Korea. This report summarizes the vetting and approval process defectors from North Korea must pass through to be eligible to take the national medical licensing examination. Defectors must pass an oral test conducted by the National Health Personnel Licensing Examination Board to be eligible to sit for the exam. From 2002 to August 2011, 41 North Korean defectors applied for the approval process to take the exam. Twenty-nine were approved (70.7%): 23 physicians, 1 dentist, 2 oriental medical doctor, 1 nurse, and 2 pharmacists. Out of 29 approved, 11 passed the licensing examination (39.3%). This report also highlights the difficulty in assessing North Korean defectors' eligibility by oral test, and suggests that adequate competency should be emphasized to recognize their unique abilities as healthcare personnel.

Immigration, barriers to healthcare and transnational ties: A case study of South Korean immigrants in Toronto, Canada.

Wang, Lu; Kwak, Min-Jung

2015-05-01

The paper analyzes the healthcare-seeking behavior of South Korean immigrants in Toronto, Canada, and how transnationalism shapes post-migration health and health-management strategies. Built upon largely separate research areas in ethnicity and health, health geography, and transnationalism, the paper conceptualizes immigrant health as influenced by individual characteristics, the migration and resettlement experience, and place effects at both a local and a transnational scale. A mixed-method approach is used to capture insights into health status and experiences in accessing local and transnational healthcare among South Korean immigrants - a fast growing visible minority group in Canada. Statistical analysis of data from the Canadian Community Health Survey discloses patterns and trends in health and healthcare use among the Korean Canadian, overall foreign-born, and native-born populations. Focus groups reveal in-depth information on the decline of Korean immigrants' health status and the array of sociocultural, economic and geographic barriers in accessing healthcare in Canada, which gave rise to their transnational use of health resources in the home country. The transnational strategies included traveling to South Korea for medical examinations or treatment, importing medications from South Korea to Canada, and consulting health resources in South Korea by phone or email. The results provide timely knowledge on how a recent immigrant group adapts to Canada in the domain of health and adds a transnational perspective to the literature on ethnicity and health.

Backpack palsy (BPP) is a common aetiology of brachial plexopathy in military hospitals. We aimed to determine the incidence and risk factors of BPP in young Korean soldiers. We identified enlisted patients who were diagnosed with BPP from a review of the medical records of all the Korean military hospitals in 2011 and 2012 and investigated their clinical findings and medical study results. To identify risk factors of BPP, we also surveyed, by questionnaire, healthy recruits of a company in a training centre who had just finished night marches. We divided them according to whether they had paresthaesia and/or weakness in their arm(s) during marching and compared their characteristics. The incidence of BPP in Korean soldiers was 29.7 per 100,000 person-years (95% CI 17.2 to 24.3). Body mass index (BMI) was significantly lower in patients with BPP than it was in healthy recruits. Among healthy recruits, those who had experienced paresthaesia and/or weakness during marching had a significantly lower BMI than did those who had not. We report the incidence of BPP in young Korean soldiers. A low BMI was a risk factor for BPP. These results may be helpful in establishing a strategy for the prevention of BPP in the setting of military training. Published by the BMJ Publishing Group Limited.

[The beginning of western medical education].

PubMed

Kee, C D

1992-01-01

Our country had quite an advanced system of medical education during the era of the Koryo Kingdom, and during the Choson Dynasty, the Kyong Guk Dae Jon, in which a systematized medical education was clearly described, was compiled in the era of King Sejong. However, the educational system was not for Western medicine. Western medicine was first introduced to our country in the 9th year of King Injo (1631) when Chong Du Won, Yi Yong Jun, etc. returned from Yon Gyong (Beiuin) with Chik Bang Oe Gi. Knowledge of Western medicine was disseminated by Shil Hak (practical learning) scholars who read a translation in Chinese characters, of Chik Bang Oe Gi. Yi Ik (Song Ho), Yi Gyu Gyong (O ju), Choe Han Gi (Hye Gang), Chong Yak Yong (Ta San), etc., read books of Western medicine and introduced in writing the excellent theory of Western medicine. In addition, Yu Hyong Won (Pan Gye), Pak Ji Won (Yon Am), Pak Je Ga (Cho Jong), etc., showed much interest in Western medicine, but no writings by them about western medicine can be found. With the establishment of a treaty of amity with Japan in the 13th year of King Kojong (1876), followed by the succession of amity treaties with Western powers, foreigners including medical doctors were permitted to flow into this country. At that time, doctors Horace N. Allen, W. B. Scranton, John W. Heron, Rosetta Sherwood (Rosetta S. Hall), etc., came to Korea and inaugurated hospitals, where they taught Western medicine to Korean students. Dr. Horace N. Allen, with the permission of king Kojong, established Che Jung Won in April 1885, and in March 1886, he began at the hospital to provide education of Western medicine to Korean students who were recrutied by the Korean Government. However, the education was not conduted on a regular basis, only training them for work as assistants. This is considered to be the pioneer case of Western medical education in this country. Before that time, Japanese medical doctors came to Korea, but there are no records showing they conducted medical education. There is a documont showing that Chi Sok Yong, who not a medical doctor, accompanied a diplomatic mission to Japan in 1880, and returned with the technique of vaccination. As a Korean, he was the first to learn and introduce western medicine to this country.

Cancer imposes a significant economic burden on individuals, families and society. The purpose of this study was to estimate the economic burden of cancer using the healthcare claims and cancer registry data in Korea in 2009. The economic burden of cancer was estimated using the prevalence data where patients were identified in the Korean Central Cancer Registry. We estimated the medical, non-medical, morbidity and mortality cost due to lost productivity. Medical costs were calculated using the healthcare claims data obtained from the Korean National Health Insurance (KNHI) Corporation. Non-medical costs included the cost of transportation to visit health providers, costs associated with caregiving for cancer patients, and costs for complementary and alternative medicine (CAM). Data acquired from the Korean National Statistics Office and Ministry of Labor were used to calculate the life expectancy at the time of death, age- and gender-specific wages on average, adjusted for unemployment and labor force participation rate. Sensitivity analysis was performed to derive the current value of foregone future earnings due to premature death, discounted at 3% and 5%. In 2009, estimated total economic cost of cancer amounted to $17.3 billion at a 3% discount rate. Medical care accounted for 28.3% of total costs, followed by non-medical (17.2%), morbidity (24.2%) and mortality (30.3%) costs. Given that the direct medical cost sharply increased over the last decade, we must strive to construct a sustainable health care system that provides better care while lowering the cost. In addition, a comprehensive cancer survivorship policy aimed at lower caregiving cost and higher rate of return to work has become more important than previously considered.

Park, K J; Peterson, L M

1991-01-01

Korean women's health beliefs and childbirth experiences in the United States were examined. A convenience sampling procedure was used, and face-to-face interviews were conducted in Korean. Interviews were audiotaped, typed, and translated from Korean to English. These women had a holistic concept of health. Some practices were influence by ancient Chinese medicine. Childbirth experiences indicated that language is a barrier requiring specific interventions. Recommendations include (a) development of an assessment tool with which health-care professionals can identify individual health beliefs early in pregnancy; (b) development of a bilingual pamphlet about medical terms and the U.S. health-care system; (c) development of a short bilingual dictionary of common foods for use in menu selection during hospitalization; and (d) provision of English practice periods based on anticipatory guidance principles to prepare women to ask for specific assistance.

2014-01-01

The purpose of this paper is to review Hwa-Byung, a cultural syndrome specific to Koreans and Korean immigrants. Hwa-Byung is a unique diagnosis and differs from other DSM disorders. However, Hwa-Byung has frequent comorbidity with other DSM disorders such as anger disorders, generalized anxiety disorder, and major depressive disorder. There are several risk factors for Hwa-Byung including psychosocial stress caused by marital conflicts and conflicts with their in-laws. Previous interventions of the Hwa-Byung syndrome were based primarily on the medical model. Therefore, based on previous research, we present a new ecological model of Hwa-Byung. We also recommend some areas of future research as well as present some limitations of our ecological model. Finally, we discuss some treatment issues, particularly for Korean women in the United States. PMID:25408922

Negotiating last-minute concerns in closing Korean medical encounters: the use of gaze, body and talk.

PubMed

Park, Yujong

2013-11-01

Although patients may raise new concerns during any time of the medical visit, the closing phase of the consultation is a critical locus for the negotiation of the topicalization of additional concerns. Using conversation analysis as the primary method of analysis, this study provides an analysis of the structure of consultation "closings" in Korean primary-care encounters and the way in which the organization of closings in this context discourages patients' presentation of additional concerns. Data are drawn from 60 videotaped primary-care encounters collected from Korea, between 2007 and 2008. The rare occasions in which last-minute concerns are raised are closely analyzed to reveal that the organization of gaze and body orientation play an important role in foreclosing the presentation of additional concerns. The results contribute to our understanding of closings in the primary-care interview by investigating a non-western setting that includes an investigation of an understudied subject--that of embodied resources--and shows how these closings serve the doctor's purpose of bringing closure in the face of last-minute concerns broached by the patient. The cultural meaning of gaze in the Korean medical care context is also discussed. The findings have implications for research on nonverbal communication, cultural differences, and interactions in medical care. Copyright © 2013 Elsevier Ltd. All rights reserved.

Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy. © 2017 The Korean Academy of Medical Sciences.

2012-01-01

Purpose This study aimed to estimate the prevalence and incidence of cerebrovascular disease (CVD) and stroke in Korean male adolescents. Materials and Methods The authors reviewed all medical certificates, medical records, and radiologic images from the examinations of Korean military conscription from January 2008 to May 2011. Results Of the 101156 examinees, 40 had CVD and stroke during adolescence. The overall prevalence and incidence of CVD and stroke was 39.54 cases per 100000 adolescents and 2.08 cases per 100000 adolescents per year, respectively and these were similar to the worldwide data. There were 3 cases of aneurysm, 3 cases of dural arteriovenous fistula, 11 cases of arteriovenous malformation, 4 cases of cavernous hemangioma, 4 cases of cerebrovascular infarction, 16 cases of Moyamoya disease, and 1 case of missing data. The incidence of arteriovenous malformation (0.57 cases per 100000 adolescents per year) was lower than the incidence for the worldwide general population. The incidence of Moyamoya disease was higher than that in any other country (15.82 cases per 100000 adolescents, vs. 0.83 cases per 100000 adolescents per year). Conclusion We observed ischemic and hemorrhagic stroke, each accounting for approximately half of cases, and high incidence of Moyamoya disease with low incidence of arteriovenous malformation in Korean male adolescents.

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs. The group researched all articles and major foreign CPGs published in English until December 2015 using several search engines. Based on these articles, levels of evidence and grades of recommendations were determined by our society as well as by other related Quality Control Committees from neurointervention, neurology and rehabilitation medicine. The Korean version of the CPGs for aSAHs includes risk factors, diagnosis, initial management, medical and surgical management to prevent rebleeding, management of delayed cerebral ischemia and vasospasm, treatment of hydrocephalus, treatment of medical complications and early rehabilitation. The CPGs are not the absolute standard but are the present reference as the evidence is still incomplete, each environment of clinical practice is different, and there is a high probability of variation in the current recommendations. The CPGs will be useful in the fields of clinical practice and research. PMID:29526058

Objective The authors surveyed the prevalence and the clinical character of lumbar disc herniation (LDH) in Korean male adolescents, and the usefulness of current conscription criteria. Methods The data of 39,673 nineteen-year-old males that underwent a conscription examination at the Seoul Regional Korean Military Manpower Administration (MMA) from October 2010 to May 2011 were investigated. For those diagnosed as having lumbar disc herniation, prevalences, subject characteristics, herniation severities, levels of herniation, and modified Korean Oswestry low back pain disability scores by MMA physical grade were evaluated. The analysis was performed using medical certificates, medical records, medical images, and electromyographic and radiologic findings. Results The prevalence of adolescent LDH was 0.60%(237 of the 39,673 study subjects), and the prevalence of serious adolescent LDH with thecal sac compression or significant discogenic spinal stenosis was 0.28%(110 of the 39,673 study subjects). Of the 237 adolescent LDH cases, 105 (44.3%) were of single level LDH and 132 (55.7%) were of multiple level LDH, and the L4-5 level was the most severely and frequently affected. Oswestry back pain disability scores increased with herniation severity (p<0.01), and were well correlated with MMA grade. Conclusions In this large cohort of 19-year-old Korean males, the prevalence of adolescent LDH was 0.60% and the prevalence of serious adolescent LDH, which requires management, was relatively high at 0.28%. MMA physical grade was confirmed to be a useful measure of the disability caused by LDH. PMID:26064143

The questionnaire was sent to 208 medical institutions performing cytopathologic examinations in Korea. Individual institutions were asked to submit their annual cytology statistical reports and gynecologic cytology-histology correlation data for 2015. Results Responses were obtained from 206 medical institutions including 83 university hospitals, 87 general hospitals, and 36 commercial laboratories. A total of 8,284,952 cytologic examinations were performed in 2015, primarily in commercial laboratories (74.9%). The most common cytology specimens were gynecologic samples (81.3%). Conventional smears and liquid-based cytology were performed in 6,190,526 (74.7%) and 2,094,426 (25.3%) cases, respectively. The overall diagnostic concordance rate between cytologic and histologic diagnoses of uterine cervical samples was 70.5%. Discordant cases were classified into three categories: category A (minimal clinical impact, 17.4%), category B (moderate clinical impact, 10.2%), and category C (major clinical impact, 1.9%). The ratio of atypical squamous cells of undetermined significance to squamous intraepithelial lesion was 1.6 in university hospitals, 2.9 in general hospitals, and 4.9 in commercial laboratories. Conclusions This survey reveals the current status and trend of cytology practices in Korea. The results of this study can serve as basic data for the establishment of nationwide cytopathology policies and quality improvement guidelines in Korean medical institutions. PMID:28950443

This study aimed to develop a Korean version of the Type D Personality Scale-14 (DS14) and evaluate the psychiatric symptomatology of Korean cardiac patients with Type D personality. Healthy control (n = 954), patients with a coronary heart disease (n = 111) and patients with hypertension and no heart disease (n = 292) were recruited. All three groups completed DS14, the Eysenck Personality Questionnaire (EPQ), the state subscale of Spielberger State and Trait Anxiety Inventory (STAI-S), the Center for Epidemiologic Studies Short Depression Scale (CESD), and the General Health Questionnaire (GHQ). The Korean DS14 was internally consistent and stable over time. 27% of the subjects were classified as Type D. Type D individuals had significantly higher mean scores on the STAI-S, CESD, and GHQ compared to non-Type D subjects in each group. The Korean DS14 was a valid and reliable tool for identifying Type D personality. The general population and cardiovascular patients with Type D personality showed higher rate of depression, anxiety and psychological distress regarding their health. Therefore, identifying Type D personality is important in clinical research and practice in chronic medical disorders, especially cardiovascular disease, in Korea.

Surgery is a demanding and stressful field in Korea. Occupational stress can adversely affect the quality of care, decrease job satisfaction, and potentially increase medical errors. The aim of this study was to investigate the occupational stress and career satisfaction of Korean surgeons. We have conducted an electronic survey of 621 Korean surgeons for the occupational stress. Sixty-five questions were used to assess practical and personal characteristics and occupational stress using the Korean occupational stress scale (KOSS). The mean KOSS score was 49.31, which was higher than the average of Korean occupational stress (45.86) or that of other specialized professions (46.03). Young age, female gender, long working hours, and frequent night duties were significantly related to the higher KOSS score. Having spouse, having hobby and regular exercise decreased the KOSS score. Multiple linear regression analysis showed that long working hours and regular exercise were the independent factors associated with the KOSS score. Less than 50% of surgeons answered that they would become a surgeon again. Most surgeons (82.5%) did not want to recommend their child follow their career. Korean Surgeons have high occupational stress and low level of career satisfaction.

Box Office Forecasting considering Competitive Environment and Word-of-Mouth in Social Networks: A Case Study of Korean Film Market.

Accurate box office forecasting models are developed by considering competition and word-of-mouth (WOM) effects in addition to screening-related information. Nationality, genre, ratings, and distributors of motion pictures running concurrently with the target motion picture are used to describe the competition, whereas the numbers of informative, positive, and negative mentions posted on social network services (SNS) are used to gauge the atmosphere spread by WOM. Among these candidate variables, only significant variables are selected by genetic algorithm (GA), based on which machine learning algorithms are trained to build forecasting models. The forecasts are combined to improve forecasting performance. Experimental results on the Korean film market show that the forecasting accuracy in early screening periods can be significantly improved by considering competition. In addition, WOM has a stronger influence on total box office forecasting. Considering both competition and WOM improves forecasting performance to a larger extent than when only one of them is considered.

While organ transplantation has been established in the medical imagination since the 1960s, this technology is currently undergoing a popular re-imagination in the era of global capitalism. As transplantation procedures have become routine in medical centers in non-Western and developing nations and as organ sales and transplant tourism become increasingly common, organs that function as a material resource increasingly derive from subaltern bodies. This essay explores this development as represented in Korean filmmaker Park Chan-wook's 2002 Sympathy for Mr. Vengeance, focusing on the ethnic and class characteristics of the global market in organs and possible modes of counter-logic to transplant technologies and related ethical discourses.

Formative research on the primo vascular system and acceptance by the korean scientific community: the gap between creative basic science and practical convergence technology.

Kim, Hoon Gi

2013-12-01

The purpose of this study was to trace the formative process of primo vascular system (PVS) research over the past decade and to describe the characteristics of the Korean scientific community. By publishing approximately 30 papers in journals ranking in the Science Citation Index (Expanded), the PVS research team actively convinced domestic and international scientists of the anatomical existence of the PVS and its possible application to Korean and Western medicine. In addition, by sharing the PVS observation technique, the team promoted the dissemination and further pursuit of the research. In 2012, however, PVS researchers performed smaller scale research without advancing to a higher level as compared to the early days. The main reasons were found to be the Korean Research and Development policy of supporting creative, small-scale basic research and applied research of Western scientific fields that promised potentially greater success on an extensive scale; the indifference concerning, and the disbelief in, the existence of a new circulatory system were shown by the Western medical community. In addition, the Oriental medical community was apathetic about working with the PVS team. Professors Kwang-Sup Soh and Byung-Cheon Lee were the prime movers of PVS research under difficult conditions. Spurred by their belief in the existence and significance of the PVS, they continued with their research despite insufficient experimental data. The Korean scientific community is not ready to promote the Korea-oriented creative field of the PVS team. Copyright © 2013. Published by Elsevier B.V.

There have been few population-based studies reporting medical, lifestyle and psychological factors associated with irregular menstrual cycles. This study aimed to elucidate the prevalence and related factors of irregular menstrual cycles in Korean women. Cross-sectional data from the 5th Korean National Health and Nutrition Examination Survey were used. Eligible women were 19-40 years old, not currently taking oral contraceptives or using intrauterine devices, and not currently pregnant or breast feeding, and had no medical history of hysterectomy, thyroid diseases, cancers or renal failure. Finally, 3194 premenopausal women were recruited in this study. The prevalence and related factors of irregular cycles were obtained using a general linear model and logistic regression analyses in a complex sampling design. The prevalence of irregular cycles was 14.3%. Age and high-education level were associated with lower odds ratios (ORs) for irregular cycles (OR 0.91, 95% confidence interval (95% CI) 0.87-0.96, and OR 0.58, 95% CI 0.38-0.88, respectively). The ORs of body mass index, perceived stress and depressive mood were 1.05 (95% CI 1.01-1.10), 1.46 (95% CI 1.11-1.92) and 2.07 (95% CI 1.18-3.63), respectively. Age, perceived stress, body mass index, depressive mood and education level, rather than obstetric factors or metabolic diseases were significant factors associated with irregular menstrual cycles in Korean women. Of these factors, perceived stress is the most significant factor associated with increased irregular menstrual cycles.

Chronic obstructive pulmonary disease (COPD) results in high morbidity and mortality among patients both domestically and globally. The Korean clinical practice guideline for COPD was revised in 2014. It was drafted by the members of the Korean Academy of Tuberculosis and Respiratory Diseases, as well as participating members of the Health Insurance Review and Assessment Service, Korean Physicians' Association, and Korea Respiration Trouble Association. This revised guideline covers a wide range of topics, including the epidemiology, diagnosis, assessment, monitoring, management, exacerbation, and comorbidities of COPD in Korea. We drafted a guideline on COPD management by performing systematic reviews on the topic of management with the help of a meta-analysis expert. We expect this guideline will be helpful medical doctors treating patients with respiratory conditions, other health care professionals, and government personnel in South Korea. PMID:28747955

This study was conducted to investigate the current role of medical oncologists in cancer care with a focus on increasing the recognition of medical oncology as an independent specialty. Questionnaires modified from the Medical Oncology Status in Europe Survey dealing with oncology structure, resources, research, and patterns of care given by medical oncologists were selected. Several modifications were made to the questionnaire after feedback from the insurance and policy committee of the Korean Association for Clinical Oncology (KACO). The online survey was then sent to KACO members. A total of 214 medical oncologists (45.8% of the total inquiries), including 71 directors of medical oncology institutions, took the survey. Most institutions had various resources, including a medical oncology department (94.1%) and a department of radiation oncology (82.4%). There was an average of four medical oncologists at each institution. Medical oncologists were involved in various treatments from diagnosis to end-of-life care. They were also chemotherapy providers from a wide range of institutions that treated many types of solid cancers. In addition, 86.2% of the institutions conducted research. This is the first national survey in Korea to show that medical oncologists are involved in a wide range of cancer treatments and care. This survey emphasizes the contributions and proper roles of medical oncologists in the evolving health care environment in Korea.

To report outcomes with regard to clinical aspects and medical costs of adenotonsillectomy and tonsillectomy at a single institution before and after implementation of the Diagnosis-Related Groups (DRG) payment system in Korea. We retrospectively reviewed the records of patients treated with adenotonsillectomy or tonsillectomy between July 2012 and June 2014. The Korean DRG payment system was applied to seven groups of specific diseases and surgeries including adenotonsillectomy and tonsillectomy from July 2013 at all hospitals in Korea. We divided patients into four groups according whether the fee-for-service (FFS) or DRG payment system was implemented and operation type (FFS-adenotonsillectomy (AT), DRG-AT, FFS-tonsillectomy (T), and DRG-T). A total of 1402 patients were included (485 FFS-AT, 490 DRG-AT, 203 FFS-T, and 223 DRG-T). The total medical cost of the DRG-AT group was significantly lower than that of the FFS-AT group (1191±404 vs. 1110±279 USD, P<0.05). There were no significant differences in length of hospital stay or postoperative complications among groups. The Korean DRG system for adenotonsillectomy and tonsillectomy reduced medical costs and clinical outcomes were not significantly altered by the adoption of the DRG system. 4.

Abstract Background: Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE). Thus, this review will aim to evaluate the current evidence on the efficacy of integrative medicine for the management of lupus nephritis in patients with SLE. Methods and analyses: The following electronic databases will be searched for studies published from their dates of inception February 2018: Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as 6 Korean medical databases (Korea Med, the Oriental Medicine Advanced Search Integrated System [OASIS], DBpia, the Korean Medical Database [KM base], the Research Information Service System [RISS], and the Korean Studies Information Services System [KISS]), and 1 Chinese medical database (the China National Knowledge Infrastructure [CNKI]). Study selection, data extraction, and assessment will be performed independently by 2 researchers. The risk of bias (ROB) will be assessed using the Cochrane ROB tool. Dissemination: This systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy. Trial registration number: PROSPERO 2018 CRD42018085205 PMID:29595669

Two-Phase chief complaint mapping to the UMLS metathesaurus in Korean electronic medical records.

The task of automatically determining the concepts referred to in chief complaint (CC) data from electronic medical records (EMRs) is an essential component of many EMR applications aimed at biosurveillance for disease outbreaks. Previous approaches that have been used for this concept mapping have mainly relied on term-level matching, whereby the medical terms in the raw text and their synonyms are matched with concepts in a terminology database. These previous approaches, however, have shortcomings that limit their efficacy in CC concept mapping, where the concepts for CC data are often represented by associative terms rather than by synonyms. Therefore, herein we propose a concept mapping scheme based on a two-phase matching approach, especially for application to Korean CCs, which uses term-level complete matching in the first phase and concept-level matching based on concept learning in the second phase. The proposed concept-level matching suggests the method to learn all the terms (associative terms as well as synonyms) that represent the concept and predict the most probable concept for a CC based on the learned terms. Experiments on 1204 CCs extracted from 15,618 discharge summaries of Korean EMRs showed that the proposed method gave significantly improved F-measure values compared to the baseline system, with improvements of up to 73.57%.

This study aims to identify how problem-based learning (PBL) has been implemented in Korean medical education, and how it is evaluated by each medical school. For this study, a total of 40 medical schools in Korea were surveyed via e-mail. The survey tool was a questionnaire consisting of 22 questions which was developed independently by the researchers. Of the 40 medical schools, 35 schools were implementing PBL programs in their medical curriculum, while five were found not currently to be running the program. A large number of the schools which introduced PBL (30 schools, 85.7%) used a hybrid PBL model. In over 70% of the medical schools surveyed, professors evaluated the effects of PBL as positive. Most medical schools (85.7%) stated they would maintain or expand their use of PBL. However, the lack of understanding and skeptical attitude of the faculty on PBL, the lack of self-study time and passive attitude of students, insufficiency of good PBL cases, and the perfunctory PBL introduction for school accreditation interfere with the successful PBL. PBL has been incorporated in Korean medical curriculum as hybrid PBL type. It is analyzed that intensive tutor training and good PBL case development are necessary for the success and effective operation of PBL.

Background The National Health Insurance Service (NHIS) recently signed an agreement to provide limited open access to the databases within the Korean Diabetes Association for the benefit of Korean subjects with diabetes. Here, we present the history, structure, contents, and way to use data procurement in the Korean National Health Insurance (NHI) system for the benefit of Korean researchers. Methods The NHIS in Korea is a single-payer program and is mandatory for all residents in Korea. The three main healthcare programs of the NHI, Medical Aid, and long-term care insurance (LTCI) provide 100% coverage for the Korean population. The NHIS in Korea has adopted a fee-for-service system to pay health providers. Researchers can obtain health information from the four databases of the insured that contain data on health insurance claims, health check-ups and LTCI. Results Metabolic disease as chronic disease is increasing with aging society. NHIS data is based on mandatory, serial population data, so, this might show the time course of disease and predict some disease progress, and also be used in primary and secondary prevention of disease after data mining. Conclusion The NHIS database represents the entire Korean population and can be used as a population-based database. The integrated information technology of the NHIS database makes it a world-leading population-based epidemiology and disease research platform. PMID:25349827

This study introduces the Clinical practice guidelines (CPGs) appraisal system by the Korean Academy of Medical Sciences (KAMS). Quality management policies for CPGs vary among different countries, which have their own cultures and health care systems. However, supporting developers in guideline development and appraisals using standardized tools are common practices. KAMS, an organization representing the various medical societies of Korea, has been striving to establish a quality management system for CPGs, and has established a CPGs quality management system that reflects the characteristics of the Korean healthcare environment and the needs of its users. KAMS created a foundation for the development of CPGs, set up an independent appraisal organization, enacted regulations related to the appraisals, and trained appraisers. These efforts could enhance the ability of each individual medical society to develop CPGs, to increase the quality of the CPGs, and to ultimately improve the quality of the information available to decision-makers.

Malnutrition and subsequent ischemic heart disease in former prisoners of war of World War II and the Korean conflict.

PubMed

Page, W F; Ostfeld, A M

1994-12-01

The harsh treatment of former prisoners of war (POWs) of World War II and the Korean conflict resulted in severe malnutrition. Although rarely linked to specific long-term medical problems, a specific marker of malnutrition, self-reported lower limb edema (presumably due to a vitamin B deficiency) was associated with a three-fold increase in subsequent death attributed to ischemic heart disease (IHD) during the follow-up period from 1967 through 1975. Although there is at present no medical basis for linking edema, which is perhaps a marker for some unmeasured risk factor, to subsequent IHD, this finding may nonetheless have medical implications for the group of former POWs and other populations with severe dietary deficiency. It also suggests there may be a need to reexamine currently held theories on malnutrition and subsequent chronic disease.

This study was done to explore and understand acculturation focusing on reproductive health of immigrant women. For the research sixteen immigrant women were selected by snowball sampling. Qualitative data were accumulated by in-depth interviews and private document collection. Raw data was analyzed following Mandelbaum's conceptual framework. The dimensions of immigrant women consisted of existence: emerging from the new environment in which it was hard to communicate and to get acquainted with others, reproduction: in the absence of learning and experience, reproductive health crisis, parenting: unmanageable burden. Turnings of life involved 'Inconvenience in one's eyes, vent for conflict and tension: pregnancy', 'strange medical care: accoucheur, rapid medical service', 'pain of morning sickness: poor maternal nutrition', 'manifestation of protective instinct for life'. In adaptations, content was as follows. 1) Standing alone as a Korean housewife, 2) Becoming aware of Korean maternal instinct: thirst for education supporting, 3) Rediscovery of family: growing maternal sense of existence. The results of this study show the acculturation process and the meaning of events related to reproductive health in current lives and can contribute to an integrated understanding of married immigrant women in Korean culture.

In this study, I aim to reveal how Lee Gyoojoons medicine has given birth to a current of learning, the supporting yang current of learning, and describe its historical significance. Before anything, I'd like to throw the question of whether if there were any currents within the traditional Korean medicine. There are no records of medical currents being widely discussed until now in medical history of Korea; however, the current of Lee Jema's sasang medicine is the most noticeable one. Among the contemporaries of Lee Jema, during the late Chosun, there was also another famed medical practitioner called Lee Gyoojoon. Lee Gyoojoon mainly practiced his medicine within Pohang, Gyeongsangbuk-do area, his apprentices have formed a group and have succeeded his medical practice. Based on the analyses of Lee Gyoojoon's apprentices and the Somun Oriental Medical Society, which is known as a successor group to Lee Gyoojoon's medicine today, they are fully satisfying the five requirements to establish a medical current: first, they held Lee Gyoojoon as the first and foremost, representative practitioner of their current; second, they advocate the supporting yang theory suggested by Lee Gyoojoon, which is originated from his theory of Mind; third, books such as the Major Essentials of Huangdi's Internal Classic Plain Questions, and the Double Grinded Medical Mirror, were being used as the main textbooks to educate their students or to practice medicine. Fourth, Lee Gyoojoon's medical ideas were being transcended quite clearly within his group of apprentices, including Seo Byungoh, Lee Wonse, and the Somun Oriental Medical Society. Fifth, Lee Gyoojoon's apprentices were first produced through the Sukgok School, however, nowadays they are being produced through medical groups formed by Lee Wonse, the Somun Oriental Medical Society, regarding the propagation of medical theories, compilation of textbooks, publication of academic journals, etc. Then, what do the existence of the supporting yang current have their significances in history? First of all, Heo Joon, the great medical practitioner in 16th century Chosun, have revealed through his book the Treasured Mirror of Eastern Medicine (TMEM), that the essence of Eastern medicine differentiated from South and North medicine of China is being transcended in Korean medicine. However, we have not got a clear conclusion on what his views of the essence of Eastern medicine is. The TMEM is the legacy of Neo-confucianism, dominant in the Chosun at the time, and is considered the reference which covers from Taoism to Korean Medicine, that is practical as well as systematical in categorizing illnesses, their respective prescriptions, and herbs. Maybe, it seems that such characteristics of the TMEM naturally led the medical practitioners and Confucian scholars, Lee Jema and Lee Gyoojoon to adopt its principles, and furthermore, possibly contributed in materializing the tradition of Eastern Medicine. Secondly, both currents appeared in the late period of Chosun dynasty. Then, weren't there any preceding medical currents before them? The bureaucratic and centralized government of the Chosun dynasty demanded and supplied talents through a nationwide examination system. However, since the late-16th century, a few family from the Chungin class have come to dominate the important medical positions as inheritance doctors , bringing about the expansion of the private medical sector, as well as growth in the number of medical practitioners. This naturally brought about fierce competition among the practitioners, and it is probable that the competition sparked the need for standardized groups and societies that follow a single medical doctrine or theory, to differentiate from the others. Probably, the birth of current of learning, which succeeded to Lee Jema and Lee Gyoojoon's medical theory, exists as an extension of this social background. The major changes in systems to build a new Chosun in 1894 brought about the abolitions of old and antique institutions. Inheritance doctors naturally collapsed, and every medical practitioners had to compete in an open market. However, Lee Jema and Lee Gyoojoon, as a medical practitioner and Confucian scholar, weren't from medical families; instead, they have successfully established and led their medical groups. The Sasang medicine current, which first began in the Hamhung area, had creative medical theories and excellent practices, naturally led the discourses traditional medicine in the center areas of the Korean peninsula. In contrast, the supporting yang current, more popular in the Youngnam area at one time, struggled to keep their current during the period of Korean War, National Industrialization and Modernization. And it was only Lee Wonse's personal dedication to the current that made it survive through the times. It was not until the late 1990s, when the apprentices have gathered Lee Gyoojoon's accomplishments, that formed the Somun Oriental Medical Society as well as the supporting yang current. In summary, the birth and the succession of the supporting yang current clearly depicts how the various traditional medical groups and societies on the periphery have survived and transcended through difficult times. And at the same time, they can provide chance to ruminate the historical flow of traditional medicine in Korea.

Many diabetic patients with vertebral fractures remain undiagnosed and untreated. We found that more than two-thirds of osteoporotic diabetic women could not be identified for pharmacological treatment according to the NOF guidelines if without radiographic vertebral assessment. This study shows the importance of radiographic vertebral assessment for identifying patients who need treatment for osteoporosis in diabetic women. Diagnosis of vertebral fracture (VF) is important for identifying patients who need pharmacologic therapy for osteoporosis. However, many patients with vertebral fractures remain undiagnosed and untreated. This study evaluated the number of patients with VFs who would be unrecognized as candidates for osteoporosis treatments according to the National Osteoporosis Foundation (NOF) Clinician’s Guidelines to the Treatment of Osteoporosis, among postmenopausal diabetic Korean women without spinal imaging. A total of 873 postmenopausal diabetic women were enrolled. Lateral plain radiographs of the thoracolumbar spine and total hip BMD were obtained. The Fracture Risk Assessment Tool (FRAX®) probability was computed using the algorithm available online at http://www.shef.ac.uk/FRAX (South Korea version). The subjects with and without VFs were classified into candidates for osteoporosis treatment [Tx+by NOF] and not candidates for osteoporosis treatment [Tx−by NOF] according to the NOF pharmacologic treatment guidelines, regardless of the presence of VFs. Forty-six percent of postmenopausal diabetic womenhad morphometric VFs. Among the subjects with morphometric VFs, only 2% of the patients had previously diagnosed VFs by medical doctors. In addition, 73.6% of the patients with VFs were not included in the [Tx+by NOF] group, given the assumption of no radiographic diagnosis of VFs. With regard to increased risk of VFs in postmenopausal Korean women with type 2 diabetes mellitus, radiographic vertebral assessment would be useful for the clinical identification of osteoporosis and fractures.

Parasitic diseases as the cause of death of prisoners of war during the Korean War (1950-1953).

PubMed

Huh, Sun

2014-06-01

To determine the cause of death of prisoners of war during the Korean War (1950-1953), death certificates or medical records were analyzed. Out of 7,614 deaths, 5,013 (65.8%) were due to infectious diseases. Although dysentery and tuberculosis were the most common infectious diseases, parasitic diseases had caused 14 deaths: paragonimiasis in 5, malaria in 3, amoebiasis in 2, intestinal parasitosis in 2, ascariasis in 1, and schistosomiasis in 1. These results showed that paragonimiasis, malaria, and amoebiasis were the most fatal parasitic diseases during the early 1950s in the Korean Peninsula. Since schistosomiasis is not endemic to Korea, it is likely that the infected private soldier moved from China or Japan to Korea.

A 37-year-old female patient with chronic and stubborn abdominal pain had been hospitalized five times in three Western hospitals, but no effects were observed. No abnormalities were found in blood tests, gastrointestinal endoscopy, sonogram, and computed tomography of the abdomen, except mild paralytic ileus. The patient decided to rely on Korean medicine as an inpatient. She was diagnosed with functional abdominal pain syndrome, and her symptom differentiation was the " Yang deficiency of spleen and kidney ." A herbal drug, Hwangikyeji-tang , along with moxibustion and acupuncture, was given to the patient. Abdominal pain and related symptoms were reduced radically within 16 days of treatment. This report shows a therapeutic potential of Korean medicine-based treatment for functional abdominal pain syndrome.

To investigate the association between level of physical activity and poor self-rated health in Korean adults. A cross-sectional study was conducted on 7,800 adults aged > or =19 years who completed the Health Interview and the Health Behavior Surveys, issued during the Third National Health and Nutrition Examination Survey (2005). The association between self-rated health and physical activity was tested using Chi-squared test. Multiple logistic regression analysis was used to calculate the odds ratios of poor self-rated health for different levels of physical activity after adjusting for physical and chronic medical conditions. The prevalence of poor self-rated health was significantly lower as the level of physical activity increased, and odds ratios for poor self-rated health were significantly lower for higher levels of physical activity after adjusting for age, marital status, educational status, smoking, alcohol consumption, and the number of physical impairments and chronic medical conditions. The association was similar in different age groups and among healthy respondents and respondents with physical impairments or chronic medical conditions. Physical activity was positively associated with self-rated health in Koreans. The independent association between a lower level of physical activity and poor self-rated health supports public health programmes that encourage regular physical activity.

The objective of this study was to review and visualize the medical informatics field over the previous 12 months according to the frequencies of keywords and topics in papers published in the top four journals in the field and in Healthcare Informatics Research (HIR) , an official journal of the Korean Society of Medical Informatics. A six-person team conducted an extensive review of the literature on clinical and consumer informatics. The literature was searched using keywords employed in the American Medical Informatics Association year-in-review process and organized into 14 topics used in that process. Data were analyzed using word clouds, social network analysis, and association rules. The literature search yielded 370 references and 1,123 unique keywords. 'Electronic Health Record' (EHR) (78.6%) was the most frequently appearing keyword in the articles published in the five studied journals, followed by 'telemedicine' (2.1%). EHR (37.6%) was also the most frequently studied topic area, followed by clinical informatics (12.0%). However, 'telemedicine' (17.0%) was the most frequently appearing keyword in articles published in HIR , followed by 'telecommunications' (4.5%). Telemedicine (47.1%) was the most frequently studied topic area, followed by EHR (14.7%). The study findings reflect the Korean government's efforts to introduce telemedicine into the Korean healthcare system and reactions to this from the stakeholders associated with telemedicine.

Specialty choice preference of medical students according to personality traits by Five-Factor Model.

Kwon, Oh Young; Park, So Youn

2016-03-01

The purpose of this study was to determine the relationship between personality traits, using the Five-Factor Model, and characteristics and motivational factors affecting specialty choice in Korean medical students. A questionnaire survey of Year 4 medical students (n=110) in July 2015 was administered. We evaluated the personality traits of Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness by using the Korean version of Big Five Inventory. Questions about general characteristics, medical specialties most preferred as a career, motivational factors in determining specialty choice were included. Data between five personality traits and general characteristics and motivational factors affecting specialty choice were analyzed using Student t-test, Mann-Whitney test and analysis of variance. Of the 110 eligible medical students, 105 (95.4% response rate) completed the questionnaire. More Agreeableness students preferred clinical medicine to basic medicine (p=0.010) and more Openness students preferred medical departments to others (p=0.031). Personal interest was the significant motivational factors in more Openness students (p=0.003) and Conscientiousness students (p=0.003). Medical students with more Agreeableness were more likely to prefer clinical medicine and those with more Openness preferred medical departments. Personal interest was a significant influential factor determining specialty choice in more Openness and Conscientiousness students. These findings may be helpful to medical educators or career counselors in the specialty choice process.

2015-12-01

This study was conducted to examine the relationship between the prevalence of burnout and its related factors in medical students in Korea. All available medical students in the metropolitan city of Daejeon, Korea, were asked to answer self-administered questionnaires from July 1 to July 26 in 2013. A total of 534 medical students participated. The Maslach Burnout Inventory-Student Survey (MBI-SS) and structured questionnaires on related factors were used. Confirmatory factor analysis and Cronbach's α were used to verify the applicability of the MBI-SS to medical students in Korea. We also performed chi-square test and logistic regression analysis to identify the factors that were associated with burnout. The MBI-SS was reliable and valid in measuring burnout in Korean medical students. Our confirmatory factor analysis approved and explained the appropriateness of the model fit. The prevalence of burnout among medical students was 26.4% (n=141). Suchrates were higher in students who were female, experienced greater levels of depression, had poor academic performance, feared dropping out, and were stressed by the poor quality of the class facilities. The MBI-SS is a valid instrument to measure academic burnout in Korean medical students. Further studies should be performed, because improvements in the mental health of medical students will benefit these doctors-to-be and their future patients.

Exposure and exclusion: disenfranchised biological citizenship among the first-generation Korean Americans.

PubMed

Kim, Taewoo; Haney, Charlotte; Hutchinson, Janis Faye

2012-12-01

Based on fieldwork with a highly uninsured and underinsured Korean American population, this article maps how the current healthcare system in the United States disenfranchises those of marginal insurance status. The vulnerability of these disenfranchised biological citizens is multiplied through exposure to disproportional health risks compounded by exclusion from essential healthcare. The first-generation Korean Americans, who commonly work in small businesses, face the double burden of increased health risks from long, stress-laden work hours and lack of access to healthcare due to the prohibitive costs of health insurance for small business owners. Even as their health needs become critical, their insurance status and costly medical bills discourage them from visiting healthcare institutions, leaving Korean Americans outside the "political economy of hope" (Good, Cult Med Psychiatry 52:61-69, 2001). Through an ethnographic examination of the daily practice of doing-without-health among a marginalized sub-group in American society, this paper articulates how disenfranchised biological citizenship goes beyond creating institutional barriers to healthcare to shaping subjectivities of the disenfranchised.

Development of a claim review and payment model utilizing diagnosis related groups under the Korean health insurance.

1993-02-01

This paper describes the development of a claim review and payment model utilizing the diagnosis related groups (DRGs) for the fee for service-based payment system of the Korean health insurance. The present review process, which examines all claims manually on a case-by-case basis, has been considered to be inefficient, costly, and time-consuming. Differences in case mix among hospitals are controlled in the proposed model using the Korean DRGs. They were developed by modifying the US-DRG system. An empirical test of the model indicated that it can enhance the efficiency as well as the credibility and objectivity of the claim review. Furthermore, it is expected that it can contribute effectively to medical cost containments and to optimal practice pattern of hospitals by establishing a useful mechanism in monitoring the performance of hospitals. However, the performance of this model needs to be upgraded by refining the Korean DRGs which play a key role in the model.

Purpose Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. Methods A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Presence of human papilloma viral DNA was detected by in situ hybridization in formalin-fixed paraffin-embedded retinoblastoma tissues using both probes against high- and low risk HPV types. Results The mean age at diagnosis was 22.0 months (range, 1.1 to 98.0 months), and the mean age at enucleation was 27.8 months (range, 1.5 to 112.7 months) among the 54 patients with retinoblastoma. HPV was not detected in any of the retinoblastoma samples using either high risk or low risk HPV probes. Conclusions Our study, being the first study in the Korean population, proposes that HPV infection may have no causal relationship with retinoblastoma in Koreans. PMID:24082775

Three of ten teenagers in Korea are addicted to mobile phones. The aim of this study was to examine the relationship between mobile phone addiction and the incidence of poor sleep quality and short sleep duration in adolescents. We used longitudinal data from the Korean Children & Youth Panel Survey conducted by the National Youth Policy Institute in Korea (2011-2013). A total of 1,125 students at baseline were included in this study after excluding those who already had poor sleep quality or short sleep duration in the previous year. A generalized estimating equation was used to analyze the data. High mobile phone addiction (mobile phone addiction score > 20) increased the risk of poor sleep quality but not short sleep duration. We suggest that consistent monitoring and effective intervention programs are required to prevent mobile phone addiction and improve adolescents' sleep quality. © 2017 The Korean Academy of Medical Sciences.

In 2014, the Korean Urological Association organized the Benign Prostatic Hyperplasia Guideline Developing Committee composed of experts in the field of benign prostatic hyperplasia (BPH) with the participation of the Korean Academy of Family Medicine and the Korean Continence Society to develop a Korean clinical practice guideline for BPH. The purpose of this clinical practice guideline is to provide current and comprehensive recommendations for the evaluation and treatment of BPH. The committee developed the guideline mainly by adapting existing guidelines and partially by using the de novo method. A comprehensive literature review was carried out primarily from 2009 to 2013 by using medical search engines including data from Korea. Based on the published evidence, recommendations were synthesized, and the level of evidence of the recommendations was determined by using methods adapted from the 2011 Oxford Centre for Evidence-Based Medicine. Meta-analysis was done for one key question and four recommendations. A draft guideline was reviewed by expert peer reviewers and discussed at an expert consensus meeting until final agreement was achieved. This evidence-based guideline for BPH provides recommendations to primary practitioners and urologists for the diagnosis and treatment of BPH in men older than 40 years. PMID:26966724

Objectives. A review on studies related to the use of Mori folium, the leaves of Morus alba, was conducted with the goal of identifying new clinical applications in Korean medicine. Methods. Global literature search was conducted using three electronic databases up to January 2015 with the term Morus alba and its Korean terms. KM literatures including textbooks and standard pharmacopoeia were separately hand-searched and reviewed to provide comparison. Data were extracted according to predetermined criteria, and clinical uses were standardized with ICD-10 categories. Results. 159 potentially relevant studies were identified, and 18 articles including 12 ethnopharmacologic and 6 clinical studies were finally included in this analysis. Ethnopharmacologic studies from 8 countries provided 17 clinical uses. We found that five out of six clinical trials were related to diabetes and suggested a moderate short-term to mild long-term effect. And 43 Korean texts also provided 156 clinical uses in 35 categories including ocular and respiratory disorders. Discussion and Conclusions. Though majority of the clinical uses were also found in Korean medicine literature, treatment of infertility, jaundice, cognitive disorder, and hyperpigmentation was found to be effective and diabetes with Morus alba was recognized to have clinical importance.

Postpartum nursing for Korean mothers.

PubMed

Schneiderman, J U

1996-01-01

Growing numbers of Korean-Americans require US health care workers to become knowledgeable of and sensitive to the cultural beliefs and customs of Korean patients. To further such understanding, health behaviors related to infant care and family involvement in the postpartum period were observed in a Los Angeles, California, hospital located in a Korean community. Notable in unassimilated Korean families were the power of the mother-in-law to assume control of decisions regarding infant care and the tendency of new mothers to defer to their mothers-in-law rather than ask nurses for advice. There is a cultural perception that the new mother is sick and unable to handle her infant. Other practices identified include a special diet of seaweed soup, avoidance of cold (including the rejection of ice packs against pain), resistance to breast feeding, preference for a male child, and modesty in the presence of men. In some cases, clinical considerations conflicted with cultural traditions. Respectful teaching, in nonverbal ways if there is a language barrier, and modeling of infant care techniques are recommended. Disregard for childbirth-associated cultural traditions on the part of medical staff can only increase the stress for the infant and family.

2014-04-01

Cancer is the leading cause of death for Korean-Americans (KAs), while cancer screening rates among KAs have been consistently low. Seven semi-structured focus group interviews with 34 KA women aged 40 or older in the Washington, DC metropolitan area were conducted to explore the perceptions of KA women about seeking physical examinations and cancer screening services in Korea. Data were analyzed using a framework approach. Informants positively perceived the use of health screening services in Korea in comparison to seeking such services in the US. Decision-making factors included cost benefits, high quality services, and more convenient screening procedures in Korea. These benefits outweighed the risks of delaying health care and travelling a vast distance with incurring additional travel costs. Motivations to seek these services in Korea included opportunities to visit their homeland and to enjoy comfortable communication with their native language. The increase of available information about Korean medical services due to the industry's aggressive marketing/PR was identified as a facilitator. Most informants did not recognize possible negative health outcomes of obtaining services in Korea such as inappropriate follow up care if having abnormal findings. Educational programs are needed to educate KAs about the benefits and risks of getting the services in Korea and proper follow up care in the US. Health care providers need to know the different cancer risks and screening needs for this population.

To survey assesses the perception of pattern identification (PI) diagnosis of Traditional Medicine (TM) by Korean medical doctors (KMDs). A total of 14,485 KMDs affiliated with the Association of Korean Medicine were sent surveys via email, and 1646 (11.1%) responded to the questionnaire on their perception of PI diagnosis. Of the 1646 respondents, more than ninety percent (1562, 94.9%) reported that they treated patients using PI. The most critical problem with PI diagnosis was the lack of objective diagnostic indicators (561, 34.1%). Ninety percent had issues diagnosing patients because of different diagnoses between KMDs (1491, 90.5% ). The majority of respondents thought herbal medicine was most related to PI (1528, 92.8%). Half of the respondents answered that PI of Ba Gang was the most commonly used PI system. Participants reported that it was most important to study standardisation of PI diagnosis and to develop standardised PI diagnoses using the classification system of the Korean Standard Classification of Diseases. The foremost PI type that physicians thought should be included in standardisation and objectification of PI ofTKM was the PI of Ba Gang. Our data suggest that we should focus on the standardisation of PI diagnosis and PI of Ba Gang in future research on PI diagnosis in TM. However, we cannot completely discount the possibility that a biased selection of subjects and a low response rate limit the generalisability of the findings.

The association between sarcopenia and cardiovascular disease (CVD) in elderly people has not been adequately assessed. The aim of this study was to investigate whether CVD is more prevalent in subjects with sarcopenia independent of other well-established cardiovascular risk factors in older Korean adults. This study utilized the representative Korean population data from the Korea National Health and Nutrition Examination Survey (KNHANES) which was conducted in 2009. Subjects older than 65 years of age with appendicular skeletal muscle mass (ASM) determined by dual energy X-ray absorptiometry were selected. The prevalence of sarcopenia in the older Korean adults was investigated, and it was determined whether sarcopenia is associated with CVD independent of other well-known risk factors. 1,578 subjects aged 65 years and older with the data for ASM were selected, and the overall prevalence of sarcopenia was 30.3% in men and 29.3% in women. Most of the risk factors for CVD such as age, waist circumference, body mass index, fasting plasma glucose and total cholesterol showed significant negative correlations with the ratio between appendicular skeletal muscle mass and body weight. Multiple logistic regression analysis demonstrated that sarcopenia was associated with CVD independent of other well-documented risk factors, renal function and medications (OR, 1.768; 95% CI, 1.075-2.909, P = 0.025). Sarcopenia was associated with the presence of CVD independent of other cardiovascular risk factors after adjusting renal function and medications.

Previous studies suggest that personality traits play an important role in academic burnout. The aim of this study was to investigate how Cloninger's temperament and character traits explain academic burnout in a highly competitive environment of medical school. A total of 184 Korean medical students participated in the survey. The Cloninger's Temperament and Character Inventory was measured around the beginning of the semester and Maslach Burnout Inventory-Student Survey at the end of the semester. The correlations and stepwise regression analysis were conducted to explain the association between personality traits and academic burnout. In addition, latent profile analysis and profile analysis were employed to distinguish and explain differences of personality traits among latent academic burnout subgroups. The higher harm avoidance of temperament and lower self-directedness and cooperativeness of character predicted the subscales of academic burnout in medical students. The Temperament and Character Inventory personality profile of high, middle, and low latent burnout subgroups were significantly different. This study showed that personality might account for the burnout level in medical education. The importance of character dimension for modulating the effects of temperament traits on academic burnout was discussed for future research.

On 26 December 2004, a huge tsunami struck the coasts of South Asian countries and it resulted in 29,729 deaths and 16,665 injuries in Sri Lanka. This study characterizes the epidemiology, clinical data and time course of the medical problems seen by a Korean disaster medical assistance team (DMAT) during its deployment in Sri Lanka, from 2 to 8 January 2005. The team consisting of 20 surgical and medical personnel began to provide care 7 days after tsunami in the southern part of Sri Lanka, the Matara and Hambantota districts. During this period, a total of 2,807 patients visited our field clinics with 3,186 chief complaints. Using the triage and refer system, we performed 3,231 clinical examinations and made 3,259 diagnoses. The majority of victims had medical problems (82.4%) rather than injuries (17.6%), and most conditions (92.1%) were mild enough to be discharged after simple management. There were also substantial needs of surgical managements even in the second week following the tsunami. Our study also suggests that effective triage system, self-sufficient preparedness, and close collaboration with local authorities may be the critical points for the foreign DMAT activity.

Parasitic Diseases as the Cause of Death of Prisoners of War during the Korean War (1950-1953)

PubMed Central

2014-01-01

To determine the cause of death of prisoners of war during the Korean War (1950-1953), death certificates or medical records were analyzed. Out of 7,614 deaths, 5,013 (65.8%) were due to infectious diseases. Although dysentery and tuberculosis were the most common infectious diseases, parasitic diseases had caused 14 deaths: paragonimiasis in 5, malaria in 3, amoebiasis in 2, intestinal parasitosis in 2, ascariasis in 1, and schistosomiasis in 1. These results showed that paragonimiasis, malaria, and amoebiasis were the most fatal parasitic diseases during the early 1950s in the Korean Peninsula. Since schistosomiasis is not endemic to Korea, it is likely that the infected private soldier moved from China or Japan to Korea. PMID:25031479

Patients with high grade chronic pulmonary obstructive disease (COPD) account for much of the COPD-related mortality and incur excessive financial burdens and medical care utilization. We aimed to determine the characteristics and medical care use of such patients using nationwide data from the Korean Health Insurance Review and Assessment Service in 2009. Patients with COPD were identified by searching with the International Classification of Diseases-10th Revision for those using medication. Patients with high grade COPD were selected based on their patterns of tertiary institute visits and medication use. The numbers of patients with high grade COPD increased rapidly in Korea during the study period, and they showed a high prevalence of comorbid disease. The total medical costs were over three times higher in patients with high grade COPD compared with those without it ($3,744 versus $1,183; P < 0.001). Medication costs comprised the largest portion of medical cost, but most impact came from hospitalization and exacerbation in both groups of patients. COPD grade and hospitalization in the previous year were the major factors affecting medical costs and days of utilizing health care resources. Patients with high grade COPD impose a high economic burden on the health care system in Korea. Prevention of progression to high grade COPD is important, both clinically and economically.

This road map aims to establish a stable and integrated healthcare system for the Korean Peninsula by improving health conditions and building a foundation for healthcare in North Korea through a series of effective healthcare programs. With a basic time frame extending from the present in stages towards unification, the roadmap is composed of four successive phases. The first and second phases, each expected to last five years, respectively, focus on disease treatment and nutritional treatment. These phases would thereby safeguard the health of the most vulnerable populations in North Korea, while fulfilling the basic health needs of other groups by modernizing existing medical facilities. Based on the gains of the first two phases, the third phase, for ten years, would prepare for unification of the Koreas by promoting the health of all the North Korean people and improving basic infrastructural elements such as health workforce capacity and medical institutions. The fourth phase, assuming that unification will take place, provides fundamental principles and directions for establishing an integrated healthcare system across the Korean Peninsula. We are hoping to increase the consistency of the program and overcome several existing concerns of the current program with this roadmap. PMID:23766871

Urologic Diseases in Korean Military Population: a 6-year Epidemiological Review of Medical Records

PubMed Central

2017-01-01

We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent. Prostatitis was the highest diagnosis made in the outpatient service, while varicocele was ranked the highest in the inpatient service. The incidence rates of urologic disease varied from 12.3 to 34.2 cases per 1,000 person-years. The urologic disease in conscripted men showed different distribution when we separated the population into conscripted and professional soldiers. Epididymoorchitis was the highest disease followed by urolithiasis, dysuresia, and balanoposthitis in 2013. This study underscores that the urologic disease has spent significant amount of health care resources in the Korean military. This calls for further study to find any significant difference and contributing factors of the urologic disease in the military and the civilian population. PMID:27914143

The purpose of this study was to investigate medical service quality, satisfaction and to examine factors influencing hospital revisit intention of the United Arab Emirates government sponsored patients in Korea. A total of 152 UAE government sponsored patients who visited Korean hospitals participated in the questionnaire survey from August to November 2016. Stepwise multiple regression was used to identify the factors that affected the revisit intention of the participants. The mean scores of medical service quality, satisfaction, and revisit intention were 5.72 out of 7, 88.88 out of 100, 4.59 out of 5, respectively. Medical service quality and satisfaction, Medical service quality and revisit intention, satisfaction and revisit intention were positively correlated. Medical service of physician, visiting routes and responsiveness of medical service quality explained about 23.8% of revisit intention. There are needs for physicians to communicate with patients while ensuring sufficient consultation time based on excellent medical skills and nurses to respond immediately for the patients' needs through an empathic encounter in order to improve medical service quality and patient satisfaction so that to increase the revisit intention of the United Arab Emirates government sponsored patients. Further, it is necessary for the hospitals to have support plans for providing country specialized services in consideration of the UAE culture to ensure that physicians' and nurses' competencies are not undervalued by non-medical service elements such as interpreters and meals.

The Japanese introduction of dentistry into Korea was for treating the Japanese residing in Korea Noda-Oji was the first Japanese dentist for Japanese people in Korea in 1893, and Narajaki doyoyo, an invited dentist was posted in the Korean headquarter of Japanese army in September, 1905. The imperialist Japan licensed the dental technicians (yipchisa) without limit and controlled them generously so they could practice dentistry freely. This measure was contrary to that in Japan. (In Japan no new dental technician was licensed.) Komori, a dental technician opened his laboratory at Chungmuro in 1902. The dental technician had outnumbered by 1920. In 1907, the first Korean dental technician Sung-Ryong Choi practiced dentistry in Jongno. The imperialist Japan made the regulations for dental technicians to set a limit to the advertisement and medical practice of dental technicians. The first Korean dentists Suk-Tae Ham was register No. 1 in the dentist license. The Kyungsung dental school was established by Nagira Dasoni for the purpose of educating some Korean people that contributed to Japanese colonization. It made progress with the help of Japan, it was was given the approval of the establishment of the professional school in January the 25th, 1929. It was intended to produce Korean dentists in the first place but became the school for Japanese students later on. The association of Chosun dentist, which had been founded by Narajaki doyoyo, was managed by Japanese dentists in favor of the colonial ruling. The Hansung Association of Dentists established in 1925 was the organization made by the necessity of the association for Koreans only. The Japanese forcefully annexed the Association of Hansung Dentists (Koreans only) to the Association of Kyungsung Dentists to avoid collective actions of Korean dentists in the name of 'Naesunilche' -- 'Japan and Korea and one'. Their invading intention was shown in the event of 'decayed tooth preventive day'. Japanese controlled the gold for dental treatment by licensing and limited the stuff for dental treatment by rationing. The association of Chosun dentists was a group organized for the academic purpose by Nagira Dasoni and etc. In October of 191, where as the association of Kyungsung dentists was constructed on the background of Nagira Dasoni. This establishment of the association of Kyungsung dentists represented a backlash against Ikuda singjo having a complete control over the association of Chosun dentists. The number of Koreans who wrote to the Chosun Dental Science Academy was 27, and they wrote 75 articles, which amounted to 15% of 486 articles. The number of Koreans who wrote to the Kyungsung Dental Science Academy was 16, and they wrote 52 articles, which amounted to 11% of 481 articles. These had been a lot of improvement by activity backlash of the dental association. However, they experimented Korean people. The experiments included the experimental stimulation of dental pain by Nagira Dasoni, use of toxic agents on human bodies such as mercury, bismuth and carcinogenic benzole, and experimental treatments with a poor prognosis. Worst of all, the rapid discrimination was stressed. The different dentition according to races was the subject of comparison researches. The dangerous chemicals were sometimes used. The non-akaloid medication was investigated to relieve the dental pain but, the habitual side effects were not unusual by the overuse of morphine or heroin, which was known to be irrelevant due to their habitual side effect. The use of new and unproven material was recommended as well. Especially, the alloy that substituted gold, attracting attention, was substantiated by researches.

Kwang Hye Won(Je Joong Won), the first western hospital in Korea, was founded in 1885. The first western Medical School in Korea was open in 1886 under the hospital management. Dr. O. R. Avison, who came to Korea in 1893, resumed the medical education there, which was interrupted for some time before his arrival in Korea. He inaugurated translating and publishing medical textbooks with the help of Kim Pil Soon who later became one of the first seven graduates in Severance Hospital Medical School. The first western medical textbook translated into Korean was Henry Gray's Anatomy. However, these twice-translated manuscripts were never to be published on account of being lost and burnt down. The existing early anatomy textbooks, the editions of 1906 and 1909, are not the translation of Gray's Anatomy, but that of Japanese anatomy textbook of Gonda. The remaining oldest medical textbook in Korean is Inorganic Materia Medica published in 1905. This book is unique among its kind that O. R. Avison is the only translator of the book and it contains the prefaces of O. R. Avison and Kim Pil Soon. The publication of medical textbook was animated by the participation of other medical students, such as Hong Suk Hoo and Hong Jong Eun. The list of medical textbooks published includes almost all the field of medicine. The medical textbooks in actual existence are as follows: Inorganic Materia Medica (1905), Inorganic Chemistry (1906), Anatomy I (1906), Physiology (1906), Diagnostics I (1906), Diagnostics II (1907), Obstetrics (1908), Organic Chemistry (1909), Anatomy (1909), and Surgery (1910).

Laparoscopic surgery in Korea increased rapidly because of the early detection of gastric cancer by the development of diagnostic tools and nationwide screening. The Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS group) played a leading role in various projects related with minimally invasive surgery. The justification of minimally invasive procedures including robotic surgery, sentinel-node biopsy, or single-port surgery/Natural Orifice Transluminal Endoscopic Surgery (NOTES) must be predetermined by the clinical trial before a wide application, and the medical industry as well as surgeons should have great responsibility.

Aging is an inevitable part of life. One can maintain well-being and wellness even after discharge and/or transition if his or her functional decline is minimized, sudden decline is prevented, and functioning is promoted during hospitalization. Caring appropriately for elderly patients requires the systematic application of Senior-Friendly Hospital principles to all operating systems, including medical centres' organization and environment, as well as patient treatment processes. The Senior-Friendly Hospital framework is valid and important for patient safety and quality improvement. This study aimed to make recommendations regarding the development of the Korean Framework for Senior-Friendly Hospitals for older patients' care management, patient safety interventions, and health promotion, via a Delphi survey. Two rounds of Delphi surveying were conducted with 15 participants who had at least 3 years' experience in accreditation surveying and medical accreditation standards, survey methods, and accreditation investigator education. In each round, we calculated statistics describing each standard's validity and feasibility. The Korean Framework for Senior-Friendly Hospitals included 4 Chapters, 11 categories, and 67 standards through consensus of the Senior-Friendly Hospitals task force and experts' peer review. After the two rounds of Delphi surveying, validity evaluation led to no changes in standards of the Senior-Friendly Hospitals; however, the number of standards showing adequate validity decreased from 67 to 58. Regarding feasibility, no changes were necessary in the standards; however, the number of categories showing adequate feasibility decreased from 11 to 8 and from 67 to 30, respectively. The excluded categories were 3.2, 4.2, and 4.3 (service, transportation, and signage and identification). The highest feasibility values were given to standards 2.1.1, 4.1.4, and 4.1.6. The highest feasibility score was given to standard 2.4.2. The Korean Framework for Senior-Friendly Hospitals needs to include 4 Chapters, 8 categories, and 30 standards. The Accreditation Program for Healthcare Organizations should include Senior-Friendly Hospitals -relevant standards considering Korea's medical environment.

Characteristics of Retractions from Korean Medical Journals in the KoreaMed Database: A Bibliometric Analysis

Cho, Hye-Min

2016-01-01

Background Flawed or misleading articles may be retracted because of either honest scientific errors or scientific misconduct. This study explored the characteristics of retractions in medical journals published in Korea through the KoreaMed database. Methods We retrieved retraction articles indexed in the KoreaMed database from January 1990 to January 2016. Three authors each reviewed the details of the retractions including the reason for retraction, adherence to retraction guidelines, and appropriateness of retraction. Points of disagreement were reconciled by discussion among the three. Results Out of 217,839 articles in KoreaMed published from 1990 to January 2016, the publication type of 111 articles was retraction (0.051%). Of the 111 articles (addressing the retraction of 114 papers), 58.8% were issued by the authors, 17.5% were jointly issued (author, editor, and publisher), 15.8% came from editors, and 4.4% were dispatched by institutions; in 5.3% of the instances, the issuer was unstated. The reasons for retraction included duplicate publication (57.0%), plagiarism (8.8%), scientific error (4.4%), author dispute (3.5%), and other (5.3%); the reasons were unstated or unclear in 20.2%. The degree of adherence to COPE’s retraction guidelines varied (79.8%–100%), and some retractions were inappropriate by COPE standards. These were categorized as follows: retraction of the first published article in the case of duplicate publication (69.2%), authorship dispute (15.4%), errata (7.7%), and other (7.7%). Conclusion The major reason for retraction in Korean medical journals is duplicate publication. Some retractions resulted from overreaction by the editors. Therefore, editors of Korean medical journals should take careful note of the COPE retraction guidelines and should undergo training on appropriate retraction practices. PMID:27706245

After graduating from Severance Medical College in 1916, Chang Sei Kim went to Shanghai to work as a missionary in a adventist hospital. The establishment of the Korean Provisional Government led him to participate in the independence movement. Educating nurses to assist the forthcoming war for independence, he seemed to realize the fact that the health of Koreans would be a key factor for achieving independence. He left for the U.S. to conduct comprehensive research on medicine. Chang Sei Kim was the first Korean to receive a Ph. D. degree of Public Health, graduating from the Johns Hopkins School of Hygiene and Public Health in 1925. He then gained an opportunity to work for Korea as a professor at Severance Medical College. His objective was the 'Reconstruction of the Korean People In Terms of Physical Constitution.' He pointed out that Koreans' weak state of health was a major reason for Korea's colonization. To gain independence, he emphasized that the Korean people should receive education on public health in order to improve the primitive conditions of sanitation. There is little doubt that Chang Sei Kim's ideas developed Heungsadan's views on medicine in terms of its stress on cultivation of ability, especially considering the fact that he was a member of the organization. As a member of the colonized who could not participate in the developing official policy, Chang Sei Kim was not able to implement his ideas fully, because an individual or a private organization could not carry out policy on public health as large a scale as the government did. Never giving up his hopes for Korean independence, he rejected requests to assume official posts in the Government-General. That was why he was particularly interested in the Self-Governing Movement in 1920s Korea. If the movement had attained its goal, he might have worked for the enhancement of sanitary environment as a director of Sanitary Department. His application for funding to establish a hygiene laboratory in Korea was rejected by Rockefeller Foundation, as the policy of foundation was to finance only government institutes, not private ones. Resigning his position at Severance Medical College in 1927. Chang Sei Kim went to Shanghai to work as a Field Director in the Council on Health Education. The council was affiliated with the Rockefeller Foundation and was founded to ameliorate the hygienic situation in China. He was well fitted to the job, because China, like Korea, shared the aim to achieve independence by promoting better health for its people and because he could be appointed as a public officer which could not happen in colonial Korea. To solve the ever-serious problems with tuberculosis in China, he went again to the U. S. to conduct research and raise money for the establishment of a sanitarium. Chang Sei Kim passed away there in 1934 at the age of 42.

This paper explores the history of the biomedical construction of women's bodies as social bodies in the formation of colonial modernity in Korea. To do so, I engage with Michel Foucault's concepts of governmentality and biopolitics and the postcolonial history of medicine that has critically revisited these Foucauldian notions. These offer critical insights into the modern calculation of population and the biomedical gaze on female bodies on the Korean Peninsula under Japan's colonial rule (1910-1945). Foucauldian reflections on governmentality and colonial medicine can also shed light on the role of biomedical physicians in the advancement of colonial biopolitics. Biomedical physicians-state and non-state employees This paper explores the history of the biomedical construction of women's bodies as social bodies in the formation of colonial modernity in Korea. To do so, I engage with Michel Foucault's concepts of governmentality and biopolitics and the postcolonial history of medicine that has critically revisited these Foucauldian notions. These offer critical insights into the modern calculation of population and the biomedical gaze on female bodies on the Korean Peninsula under Japan's colonial rule (1910-1945). Foucauldian reflections on governmentality and colonial medicine can also shed light on the role of biomedical physicians in the advancement of colonial biopolitics. Biomedical physicians-state and non-state employees and colonizers and colonized alike - served as key agents investigating, knowing, and managing, as well as proliferating a discourse about, women's bodies and reproduction during Japan's empire-building. In particular, this paper sheds light on the processes by which Korean women's bodies became the objects of intense scrutiny as part of an attempt to quantify, as well as maximize, the total population in late colonial Korea. In the aftermath of the establishment of the Manchurian puppet state in 1932, Japanese imperial and colonial states actively sought to mobilize Koreans as crucial human resources for the further penetration of Japan's imperial holdings into the Chinese continent. State and non-state medical doctors meticulously interrogated, recorded, and circulated knowledge about the sexual and conjugal practices and reproductive life of Korean women in the agricultural sector, for the purposes of measuring and increasing the size, health, and vitality of the colonial population. At the heart of such medical endeavors stood the Investigative Committee for Social Hygiene in Rural Korea and Japan-trained Korean medical students/physicians, including Chóe Ŭg-sŏk, who carried out a social hygiene study in the mid-1930s. Their study illuminates the ways in which Korean women's bodies entered the modern domain of scientific knowledge at the intersection of Japan's imperialism, colonial governmentality, and biomedicine. A critical case study of the Investigative Committee's study and Chóe can set the stage for clarifying the vestiges as well as the reformulation of knowledge, ideas, institutions, and activities of colonial biopolitics in the divided Koreas.

Objective We investigated the deficit in the recognition of facial emotions in a sample of medicated, stable Korean patients with schizophrenia using Korean facial emotion pictures and examined whether the possible impairments would corroborate previous findings. Methods Fifty-five patients with schizophrenia and 62 healthy control subjects completed the Facial Affect Identification Test with a new set of 44 colored photographs of Korean faces including the six universal emotions as well as neutral faces. Results Korean patients with schizophrenia showed impairments in the recognition of sad, fearful, and angry faces [F(1,114)=6.26, p=0.014; F(1,114)=6.18, p=0.014; F(1,114)=9.28, p=0.003, respectively], but their accuracy was no different from that of controls in the recognition of happy emotions. Higher total and three subscale scores of the Positive and Negative Syndrome Scale (PANSS) correlated with worse performance on both angry and neutral faces. Correct responses on happy stimuli were negatively correlated with negative symptom scores of the PANSS. Patients with schizophrenia also exhibited different patterns of misidentification relative to normal controls. Conclusion These findings were consistent with previous studies carried out with different ethnic groups, suggesting cross-cultural similarities in facial recognition impairment in schizophrenia.

Various types of stress affect mental health in the form of mood disorders, anxiety disorders, and suicidal ideation. Recently, the increasing suicide rate in the working-age population has become a major mental health concern in Korea. Thus, we investigated what kind of stress influence depression, anxiety, and suicidal ideation in Korean employees. The study participants were 189,965 employees who attended health screenings and responded to the Center for Epidemiologic Study-Depression Scale, the Beck Anxiety Inventory, and a questionnaire on the major causes of stress and suicidal ideation. We investigated the major causes of stress by gender and age categories and used binary logistic regression to determine the impact of the causes of stress on depression, anxiety and suicidal ideation. Of several stress causes, work-related stress was the most prevalent, regardless of age category and gender, followed by interpersonal relationships. However, interpersonal relationships and financial problems were the predominant causes of stress related to depression or suicidal ideation. This research suggests that despite the fact that work is the most common cause of stress for Korean employees, stress related to life problems other than work has a greater influence on the mental health of Korean employees. © 2017 The Korean Academy of Medical Sciences.

This study aimed to examine influenza vaccination coverage of North Korean defectors (NKD) in the Republic of Korea (Korea) and explore the factors affected the vaccination coverage. Total 378 NKD were analyzed. Four Korean control subjects were randomly matched by age and gender from the Korea National Health and Nutrition Examination Survey V (n = 1,500). The adjusted vaccination coverage revealed no statistical difference between the defectors group and indigenous group (29.1% vs. 29.5%, P = 0.915). In the aged under 50 group, the vaccination coverage of NKD was higher than that of Korean natives (37.8% vs. 25.8%, P = 0.016). However in the aged 50 yr and over group, the vaccination coverage of North Korean defectors was lower than that of the natives (28.0% vs. 37.6%, P = 0.189). Even the gap was wider in the aged 65 yr and over group (36.4% vs. 77.8%, P = 0.007). Gender and medical check-up experience within 2 yr showed association with the vaccination coverage of NKD. Influenza vaccination coverage of aged defectors' group (aged 50 yr and over) was lower than indigenous people though overall vaccination coverage was similar. Further efforts to increase influenza vaccination coverage of this group are needed.

The objective of this study was to examine the perceived health status, family support and life satisfaction of older Korean adults and the relationships among them. This study was designed to be a descriptive correlation study using questionnaire. Subjects were 246 older people who were over 65 years of age in Seoul and Daegu metropolitan city, Korea. Measures were the Cornell Medical Index-Simple Korean Form to measure the perceived health status, the Family Support Instrument to measure the family support and the Standard Life Satisfaction Instrument for Korean people to measure the life satisfaction. Perceived health state was worse as average 3.3, family support was good as average 3.4 and life satisfaction was low as average 3.1. There were statistically significant positive correlations among perceived health state, family support and life satisfaction and between family support and life satisfaction. The predictors of life satisfaction in elderly were family support, age, monthly allowance and perceived health state. These factors explained 37.5% of the total variance. The major influencing factor was family support. This cross-sectional study provides preliminary evidence that to develop nursing strategy to increase family support of older Korean adults is needed. © 2012 Blackwell Publishing Asia Pty Ltd.

Materials and Methods Cross sectional studies utilized the responses of 59 medical oncologists and 211 patients. To understand the communication gap, perceived reasons and nondisclosure of CAM use, reactions of physicians to disclosure, and expectations for CAM were analyzed. Data were compared with use of the chi-squared test. Results Both medical oncologists and patients were in accord that CAM use would privde the patients with a feeling of hope. The medical oncologists believed more often than patients to attribute CAM use for control over medical care decisions, for the treatment of an incurable disease or as a nontoxic approach (p<0.05). Regarding reasons for nondisclosure, medical oncologists were more likely to think that physicians would not understand the use of CAM, discontinue treatment or disapprove of the use of CAM (p<0.0001). Patients attributed nondisclosure mainly to the lack of questioning about CAM. Medical oncologists were more likely to warn of the risks with CAM use and less likely to encourage the use of CAM than perceived by patients (p=0.01). Patients expected that CAM could cure disease, extend survival, relieve symptoms and improve the immune system or quality of life more often than medical oncologists (p<0.05). Conclusion Given the discrepant views of medical oncologists and patients on the use of CAM, medical oncologists should be aware of the discrepancies and attempt to resolve any differences.

The purpose of this study was to explore potential factors affecting the self-management behaviors of Korean immigrants with type 2 diabetes mellitus (KIT2Ds). A qualitative descriptive design guided this study. Semistructured interviews lasting 45 to 60 minutes were conducted with 20 KIT2Ds in the participants' preferred language; in all cases, this was Korean. Each interview was audiotaped, transcribed, and analyzed using conventional content analysis. Data analysis was performed in two steps. The data written in Korean were initially analyzed by 3 bilingual researchers. A qualitative researcher then participated in the analysis to refine the findings for presentation to an English-speaking audience while staying true to the data and preserving the nuanced Korean meanings. The mean age of the sample was 64. 5 ± 11.6 years (9 men and 11 women). The mean years of staying in the United States and age at diabetes mellitus diagnosis were 23.6 ± 9.7 years and 52.5 ± 12.3 years, respectively. Three major ideas were identified: (1) issues on treatment regimen related to medications and diet, (2) resources that helped or hindered ability to manage diabetes, and (3) the physician-patient relationship. Important cultural nuances need to be addressed to better prepare KIT2Ds to manage their diabetes more effectively. A culture-specific program should extend beyond a diabetes self-management education delivered in Korean language. Rather, content and education methods need to consider acculturation effects on diabetes management behaviors.

Comparison of variant frequencies in the general population has become an essential part of the American College of Medical Genetics and Genomics (ACMG) standards and guidelines for interpreting sequence variants. We determined the optimal number of relevant ethnic controls that should be used to accurately calculate the odds ratio (OR) of genetic variants. Using the ACMG guidelines, we reclassified BRCA1 and BRCA2 mutations and variants of unknown significance in 745 Korean patients susceptible to hereditary breast and ovarian cancer compared with 1,314 Korean population controls. We observed that the ORs were falsely inflated when we analyzed several variants using non-Korean population data. Our simulation indicated that the number of controls needed for the lower limit of a 95% confidence interval to exceed 1.0 varied according to the frequency of the variant in each patient group, with more than 820 controls needed for a variant existing in 1% of cases. Using a sufficient number of relevant population data, we could efficiently classify variants and identified the BRCA1 p.Leu1780Pro mutation as a possible pathogenic founder mutation in Korean patients. Our study suggests that BRCA1 p.Leu1780Pro is a novel pathogenic mutation found in Korean patients. We also determined the optimal number of relevant ethnic controls needed for accurate variant classification according to the ACMG guidelines.

2005-11-01

The aim of this study was to identify the attitudes of elderly Korean patients toward death and dying using Q-methodology to aid in the development of basic strategies for nursing care of elderly Koreans. Thirty participants at a university hospital sorted 40 selected Q-statements on a nine-point scale. Data analysis identified three types of attitudes toward death and dying in elderly patients in Korea: religion-dependent, science-adherent, and sardonic. Religion-dependent elders are highly dependent upon religion as evidenced by their reply that they would like to rely on God and a minister the most. Science-adherent elders have great affection for life and believe in modern medical advancements. The sardonic elders regard death as the dispensation of nature so there is no need to be afraid of death and dying. This study will contribute to the understanding that nurses and other health professionals have of the perceptions of elderly Koreans about death and dying. Also, the findings may provide the basis for the development of more appropriate strategies to improve death and dying education programs of health professionals.

The objective of the study was to explore and describe the health-seeking experience of North Korean women defectors settled in South Korea. A qualitative study was conducted using Colaizzi's phenomenological method. Participants were 10 North Korean women defectors. Data were collected through in-depth, unstructured interviews with individual participants. A total of 24 themes, eight theme clusters, and four categories emerged. The structure of the health-seeking experience for them was identified as 'having new opportunities to better understand my own body and protecting my own health while adapting to the health care system of the South'. The four categories were: finding out about my own body, confusion regarding the medical treatment, enjoying the health care benefits, and protecting my own health. The findings of this study will help improve the understanding of the health-seeking experience of North Korean women defectors and provide valuable resources to assist in caring for their health needs. This will contribute to preparing the groundwork to enhance the quality of their remaining life in South Korea. © 2018 Wiley Periodicals, Inc.

This study explored the relationship between sociodemographic factors and injection utilization in South Korea. We conducted a retrospective cross-sectional analysis using 2009 prescription claims for Korean National Health Insurance beneficiaries. We analyzed the utilization, costs, and proportion of injections in the insured market for oral-injection dual-dose-form ingredients (DFIs). We included outpatients who were prescribed DFIs with no age limits. Descriptive analysis and multivariate logistic regression were performed to evaluate the predictive factors of injection use. Injections accounted for about 5% of outpatient utilization and costs of the study drugs. The odds of having injections were 1.3-1.6 times higher among those patients who are 70 years and older compared with those in the 20s, in smaller-sized hospitals and clinics than that in larger, and among medical institutions in rural areas than those in the capital area. The odds of having injections were increased stepwise for the age groups of 30-69 years. Injections were more likely to be prescribed for systematic hormonal preparations and drugs for the musculoskeletal system. The use of injections was higher among older groups, among smaller medical institutions, and among institutions in rural areas in Korean outpatient care. The difference between prescribing defined daily doses and prescribing rate for injections of the audit reports implies that Korean doctors prescribed injections often, but small doses for momentary effects in outpatient settings. Further studies are required to uncover the underlying causes of the high prevalence of injection use in older or rural populations and smaller institutions. Copyright © 2012 John Wiley & Sons, Ltd.

Background The association between sarcopenia and cardiovascular disease (CVD) in elderly people has not been adequately assessed. The aim of this study was to investigate whether CVD is more prevalent in subjects with sarcopenia independent of other well-established cardiovascular risk factors in older Korean adults. Method This study utilized the representative Korean population data from the Korea National Health and Nutrition Examination Survey (KNHANES) which was conducted in 2009. Subjects older than 65 years of age with appendicular skeletal muscle mass (ASM) determined by dual energy X-ray absorptiometry were selected. The prevalence of sarcopenia in the older Korean adults was investigated, and it was determined whether sarcopenia is associated with CVD independent of other well-known risk factors. Results 1,578 subjects aged 65 years and older with the data for ASM were selected, and the overall prevalence of sarcopenia was 30.3% in men and 29.3% in women. Most of the risk factors for CVD such as age, waist circumference, body mass index, fasting plasma glucose and total cholesterol showed significant negative correlations with the ratio between appendicular skeletal muscle mass and body weight. Multiple logistic regression analysis demonstrated that sarcopenia was associated with CVD independent of other well-documented risk factors, renal function and medications (OR, 1.768; 95% CI, 1.075–2.909, P = 0.025). Conclusions Sarcopenia was associated with the presence of CVD independent of other cardiovascular risk factors after adjusting renal function and medications. PMID:23533671

Background Patients with high grade chronic pulmonary obstructive disease (COPD) account for much of the COPD-related mortality and incur excessive financial burdens and medical care utilization. We aimed to determine the characteristics and medical care use of such patients using nationwide data from the Korean Health Insurance Review and Assessment Service in 2009. Materials and methods Patients with COPD were identified by searching with the International Classification of Diseases–10th Revision for those using medication. Patients with high grade COPD were selected based on their patterns of tertiary institute visits and medication use. Results The numbers of patients with high grade COPD increased rapidly in Korea during the study period, and they showed a high prevalence of comorbid disease. The total medical costs were over three times higher in patients with high grade COPD compared with those without it ($3,744 versus $1,183; P < 0.001). Medication costs comprised the largest portion of medical cost, but most impact came from hospitalization and exacerbation in both groups of patients. COPD grade and hospitalization in the previous year were the major factors affecting medical costs and days of utilizing health care resources. Conclusion Patients with high grade COPD impose a high economic burden on the health care system in Korea. Prevention of progression to high grade COPD is important, both clinically and economically.

To summarize the way North Korea attempted to modernize its system of traditional medicine and integrate it with Western biomedicine. We reviewed clinical textbooks and periodicals of traditional Korean medicine published in North Korea, research reports on North Korean health and medicine published elsewhere, and conducted interviews of defectors from North Korea who were students or clinicians of traditional medicine. Key findings of this study are: (1) North Korea has attempted several ways of integrating traditional medicine into education and clinical practices; (2) North Korea's communist government provided the main driving force for an integration policy; (3) school curricula of both Western and traditional Korean medicine incorporated knowledge of both disciplines, yet more weight was placed on traditional Korean medicine; (4) a combination of Western diagnosis and Korean therapeutics was the most frequent example of integration, while the dual system approach with reciprocal practice was also explored; (5) several forms of integrative therapeutic mixture were practiced including concurrent medication, injection on acupuncture points, and intramuscular or intravenous injection of extracts from medicinal plants; and (6) limited resources for research and the underdeveloped level of clinical research failed to secure rigorous scientific advancement. Despite the government-driven attempt to create an ideal integrative system of medicine, according to our findings, the actual introduction of an integrative system into practice was far from the North Korean government's anticipated outcome in regards to clinical practice. We hypothesize this was due to famine, economic crisis, and political isolation from the international realm. Traditional Korean medicine seems to have served the population, which is in desperate need of treatment amid difficulties in health, while North Korea's Western biomedicine-based health delivery system has been badly affected.

The National Health Information Standards Committee was established in 2004 in Korea. The practical subcommittee for laboratory test terminology was placed in charge of standardizing laboratory medicine terminology in Korean. We aimed to establish a standardized Korean laboratory terminology database, Korea-Logical Observation Identifier Names and Codes (K-LOINC) based on former products sponsored by this committee. The primary product was revised based on the opinions of specialists. Next, we mapped the electronic data interchange (EDI) codes that were revised in 2014, to the corresponding K-LOINC. We established a database of synonyms, including the laboratory codes of three reference laboratories and four tertiary hospitals in Korea. Furthermore, we supplemented the clinical microbiology section of K-LOINC using an alternative mapping strategy. We investigated other systems that utilize laboratory codes in order to investigate the compatibility of K-LOINC with statistical standards for a number of tests. A total of 48,990 laboratory codes were adopted (21,539 new and 16,330 revised). All of the LOINC synonyms were translated into Korean, and 39,347 Korean synonyms were added. Moreover, 21,773 synonyms were added from reference laboratories and tertiary hospitals. Alternative strategies were established for mapping within the microbiology domain. When we applied these to a smaller hospital, the mapping rate was successfully increased. Finally, we confirmed K-LOINC compatibility with other statistical standards, including a newly proposed EDI code system. This project successfully established an up-to-date standardized Korean laboratory terminology database, as well as an updated EDI mapping to facilitate the introduction of standard terminology into institutions. © 2017 The Korean Academy of Medical Sciences.

The Korean national health security system covers the entire population and all medical facilities. We aimed to estimate epilepsy prevalence, anticonvulsant utilization pattern and the cost. We identified prevalent epilepsy patients by the prescription of anticonvulsants under the diagnostic codes suggesting seizure or epilepsy from 2007 Korean National Health Insurance databases. The information of demography, residential area, the kind of medical security service reflecting economic status, anticonvulsants, and the costs was extracted. The overall prevalence of treated epilepsy patients was 2.41/1,000, and higher for men than women. The age-specific prevalence was the lowest in those in their thirties and forties. Epilepsy was more prevalent among lower-income individuals receiving medical aid. The regional prevalence was the highest in Jeju Island and lowest in Ulsan city. New anticonvulsants were more frequently used than old anticonvulsants in the younger age group. The total annual cost of epilepsy or seizure reached 0.46% of total medical expenditure and 0.27% of total expenditure on health. This is the first nationwide epidemiological report issued on epilepsy in Korea. Epilepsy prevalence in Korea is comparable to those in developed countries. Economic status and geography affect the prevalence of epilepsy.

Hepatocellular carcinoma (HCC) is the fifth most commonly occurring cancer in Korea and typically has a poor prognosis with a 5-year survival rate of only 28.6%. Therefore, it is of paramount importance to achieve the earliest possible diagnosis of HCC and to recommend the most up-to-date optimal treatment strategy in order to increase the survival rate of patients who develop this disease. After the establishment of the Korean Liver Cancer Study Group (KLCSG) and the National Cancer Center (NCC), Korea jointly produced for the first time the Clinical Practice Guidelines for HCC in 2003, revised them in 2009, and published the newest revision of the guidelines in 2014, including changes in the diagnostic criteria of HCC and incorporating the most recent medical advances over the past 5 years. In this review, we will address the noninvasive diagnostic criteria and diagnostic algorithm of HCC included in the newly established KLCSG-NCC guidelines in 2014, and review the differences in the criteria for a diagnosis of HCC between the KLCSG-NCC guidelines and the most recent imaging guidelines endorsed by the European Organisation for Research and Treatment of Cancer (EORTC), the Liver Imaging Reporting and Data System (LI-RADS), the Organ Procurement and Transplantation Network (OPTN) system, the Asian Pacific Association for the Study of the Liver (APASL) and the Japan Society of Hepatology (JSH).

Medical students face a variety of stressors associated with their education; if not promptly identified and adequately dealt with, it may bring about several negative consequences in terms of mental health and academic performance. This study examined psychometric properties of the Korean version of the Higher Education Stress Inventory (K-HESI). The reliability and validity of the K-HESI were examined in a large scale multi-site survey involving 7110 medical students. The K-HESI, Beck Depression Inventory (BDI) and questions regarding quality of life (QOL) and self-rated physical health (SPH) were administered. Exploratory factor analysis of the K-HESI identified seven factors: Low commitment; financial concerns; teacher-student relationship; worries about future profession; non-supportive climate; workload; and dissatisfaction with education. A subsequent confirmatory factor analysis supported the 7-factor model. Internal consistency of the K-HESI was satisfactory (Cronbach's α = .78). Convergent validity was demonstrated by its positive association with the BDI. Known group validity was supported by the K-HESI's ability to detect significant differences on the overall and subscale scores of K-HESI according to different levels of QOL and SPH. The K-HESI is a psychometrically valid tool that comprehensively assesses various relevant stressors related to medical education. Evidence-based stress management in medical education empirically guided by the regular assessment of stress using reliable and valid measure is warranted.

We examined the risk factors for and psychological problems associated with violence victimization in a nationwide representative sample of Korean adolescents. Data from the 2016 Korean Youth Risk Behavior Web-based Survey was used. Participants were asked about their experience of being a victim of violence that required medical treatment during the past 12 months, as well as their perceived health, happiness, sleep satisfaction, stress, depressed mood, and suicidality. The 12-month prevalence of violence victimization requiring medical treatment was 2.4%. The results indicated that adolescents were at an increased risk for violence victimization if they were male, older, had parents of a foreign nationality, did not reside with their family, worked part time, resided in small cities or rural areas, were high or low in socioeconomic status (SES), exhibited high or low levels of academic performance, used alcohol or tobacco, and were sexually active. In addition, while violence victimization was negatively associated with perceived health and happiness, it was positively associated with perceived stress, depressed mood, and suicidality. The results indicate that a social disadvantage, involvement in risky behavior, and psychological problems are associated with violence victimization. Effective violence prevention efforts should thus target high-risk groups, and clinical attention is needed to address the psychological costs associated with violence victimization. PMID:28534822

Visualization of disaster dispersion prediction enables decision makers and civilian to prepare disaster and to reduce the damage by showing the realistic simulation results. With advances of GIS technology and the theory of volcanic disaster prediction algorithm, the predicted disaster dispersions are displayed in spatial information. However, most of volcanic ash dispersion predictions are displayed in 2D. 2D visualization has a limitation to understand the realistic dispersion prediction since its height could be presented only by colour. Especially for volcanic ash, 3D visualization of dispersion prediction is essential since it could bring out big aircraft accident. In this paper, we deals with 3D visualization techniques of volcanic ash dispersion prediction with spatial information open platform in Korea. First, time-series volcanic ash 3D position and concentrations are calculated with WRF (Weather Research and Forecasting) model and Modified Fall3D algorithm. For 3D visualization, we propose three techniques; those are 'Cube in the air', 'Cube in the cube', and 'Semi-transparent plane in the air' methods. In the 'Cube in the Air', which locates the semitransparent cubes having different color depends on its particle concentration. Big cube is not realistic when it is zoomed. Therefore, cube is divided into small cube with Octree algorithm. That is 'Cube in the Cube' algorithm. For more realistic visualization, we apply 'Semi-transparent Volcanic Ash Plane' which shows the ash as fog. The results are displayed in the 'V-world' which is a spatial information open platform implemented by Korean government. Proposed techniques were adopted in Volcanic Disaster Response System implemented by Korean Ministry of Public Safety and Security.

The politics of herbal drugs in Korea.

PubMed

Cho, B H

2000-08-01

Hanbang, the Korean medical practice with origins in classical Chinese texts, is a prominent part of the Korean health care system. Hanbang physicians, called hanuisas, are looked down on by biomedical doctors, but their practice has enjoyed increasing popularity for several decades. As the market for herbal preparations has become more lucrative, biomedical pharmacists have begun to participate in it. The Pharmaceutical Act in 1993 explicitly allowed pharmacists to prescribe and dispense herbal drugs. This provoked a bitter public conflict between hanuisas and pharmacists, involving street demonstrations and strikes. The hanuisas asserted that the pharmacists were unqualified to assume their traditional practice. They also agitated for recognition in the state-sponsored system of health care and for the state's support for developing Hanbang medicine. This paper attributes the conflicts concerning Hanbang to the expanding market for herbal preparations, Korean nationalism, and to the oversupply of biomedical pharmacists.

The purpose of this study was to examine the chronological changes and progress in medical education research in Korea and to identify the less investigated topics that need further study and improvement with regard to methodological quality. Of the 590 articles that were published from 1989 to 2010 in the Korean Journal of Medical Education, 386 original research papers were extracted for the analysis. The extracted papers were systematically reviewed using 2 analysis schemes that we developed: one scheme was designed to classify research topics, and the other determined the methodology that was used. The main results were as follows: The most popular research areas were curriculum, educational method, and evaluation in basic medical education; in contrast, studies that addressed postgraduate education, continuous professional development, and educational administration were less frequent; The most frequently studied topics were clinical performance/skills evaluation, clerkship, curriculum development, and problem-based learning, Quantitative studies predominated over qualitative studies and mixed methods (265 vs. 95 vs. 26). Two hundred forty papers were descriptive, cross-sectional studies, and 17 were experimental studies. Most qualitative studies were non-participation observational studies. In conclusion, there has been dramatic growth in the extent of medical education research in Korea in the past two decades. However, more studies that investigate the graduate medical education and the continuous professional development should be performed. Moreover, robust experimental designs and methods should be applied to provide stronger evidence that can practice best-evidence medical education.

Unnecessary use of high-quality resources in general hospitals hinders treatment of patients with urgent and complicated conditions. Thus, the Korean Government has sought to reduce general hospital visiting of patients with 52 mild diseases, including hypertension. The higher cost sharing for medical expenses and medications from general hospitals were enacted in 2009 and 2011, respectively.We determined whether these regulations were effective through evaluating changing trends in first-visited healthcare organizations and defined the first visiting healthcare organization level (primary clinics, hospital, and general hospital) as an outcome measure.Data of 32,830 mild hypertension patients from 2004 to 2013 were retrieved from the Korean National Health Insurance Service National Sample Cohort. This was a retrospective study involving a large national cohort with patient samples (representing 2% of the total Korean population) stratified on the basis of sociodemographic information.Mutinomial logistic regression were performed for the first visiting to different health organizations, compared to the first visiting to primary clinics.Patients in 2012 and 2013 had significantly lower odds ("2012": 0.68, 95% confidence interval [CI]: 0.56-0.81/"2013": 0.66, 95% CI 0.54-0.81) of first visiting general hospitals compared with those in 2008, although decreased tendencies (albeit nonsignificant) were already evident in 2010 and 2011.Thus, government health policies for cost-containment seem effective in decreasing first visiting of general hospitals among patients with mild essential hypertension. These policies have since extended to Medical Aid beneficiaries; thus, it is needed to continue monitor their results carefully.

The Korean government has enacted two laws, namely, the Personal Information Protection Act and the Bioethics and Safety Act to prevent the unauthorized use of medical information. To protect patients' privacy by complying with governmental regulations and improve the convenience of research, Asan Medical Center has been developing a de-identification system for biomedical research. We reviewed Korean regulations to define the scope of the de-identification methods and well-known previous biomedical research platforms to extract the functionalities of the systems. Based on these review results, we implemented necessary programs based on the Asan Medical Center Information System framework which was built using the Microsoft. NET Framework and C#. The developed de-identification system comprises three main components: a de-identification tool, a search tool, and a chart review tool. The de-identification tool can substitute a randomly assigned research ID for a hospital patient ID, remove the identifiers in the structured format, and mask them in the unstructured format, i.e., texts. This tool achieved 98.14% precision and 97.39% recall for 6,520 clinical notes. The search tool can find the number of patients which satisfies given search criteria. The chart review tool can provide de-identified patient's clinical data for review purposes. We found that a clinical data warehouse was essential for successful implementation of the de-identification system, and this system should be tightly linked to an electronic Institutional Review Board system for easy operation of honest brokers. Additionally, we found that a secure cloud environment could be adopted to protect patients' privacy more thoroughly.

PubMed is not only includes international medical journals but also has a registration site for the ongoing clinical trials, such as ClinicalTrials.gov, under the supervision of US National Institutes of Health. We analyzed current status of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov. As of October 2012, there are total of 72 trials found on registry of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov. These trials were analyzed and classified by conditions of vaccine clinical trials, biologicals or drugs used in vaccine clinical trials, status of proceeding research, and list of sponsor and collaborators. Total 72 trials of vaccine clinical trials conducted by Korean investigators are classified by groups of infection (64 trials), cancer (4 trials), and others (4 trials). Infections group shown are as follows: poliomyelitis, pertussis, diphtheria, tetanus, and Haemophilus influenzae type b (10), influenza (9), human papillomavirus infection (8), pneumococcal vaccine (6), herpes zoster (4), smallpox (4), hepatitis B (4), etc. One trial of each in lung cancer, breast cancer, prostate cancer, and colorectal cancer are shown in cancer group. One trial of each in Crohn's disease, ulcerative colitis, renal failure, and rheumatoid arthritis are shown in other group. Vaccine clinical trials conducted by Korean investigators in ClinicalTrial.gov reflects the current status of Korean research on vaccine clinical trials at the international level and can indicate research progress. It is hoped that this aids the development of future vaccine clinical trials in Korea.

Purpose The purpose of this study was to explore potential factors affecting self-management behaviors in Korean immigrants with type 2 diabetes mellitus (KIT2Ds). Methods A qualitative descriptive design guided this study. Semi-structured interviews lasting 45-60 minutes were conducted with 20 KIT2Ds in the participant’s preferred language; in all cases this was Korean. Each interview was audio-taped, transcribed, and analyzed using conventional content analysis. Data analysis was performed in two steps. The data written in Korean were initially analyzed by three bilingual researchers. A qualitative researcher then participated in the analysis to refine the findings for presentation to an English speaking audience while staying true to the data and preserving the nuanced Korean meanings. Results The mean age of the sample was 64. 5 ± 11.6 years (9 men and 11 women). The mean years of staying in the U. S. and age at diabetes mellitus diagnosis were 23.6 ± 9.7 years and 52.5 ± 12.3 years, respectively. Three major ideas were identified: (a) issues on treatment regimen related to both medications and diet, (b) resources that helped or hindered their ability to manage diabetes, and (c) the physician/patient relationship. Conclusions There were important cultural nuances that need to be addressed to better prepare KIT2Ds to manage their diabetes more effectively. A culture specific program should extend beyond a diabetes self-management education delivered in Korean language. Rather, content and education methods need to consider acculturation effects on diabetes management behaviors. PMID:23019236

The aim of this study is to evaluate whether the triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio is associated with periodontal disease in Korean adults. This cross-sectional study included 12,249 individuals (4,941 men and 7,308 women) who took part in the 2012-2014 Korean National Health and Nutrition Examination Survey. We categorized the TG/HDL-C ratio into three groups. Periodontal disease was defined as a community pocket index score ≥3 with at least one affected site. Multiple logistic analyses were used to analyze the association between TG/HDL-C ratio and periodontal disease. In the study population, prevalence of periodontal disease was 31.6% in men and 21% in women. Compared to the lowest tertile group, OR (95% CI) of the highest tertile group for periodontal disease was 1.474 (1.220-1.780) in men and 1.259 (1.041-1.522) in women after adjusting for age, waist circumference, systolic blood pressure, fasting glucose, current smoking, alcohol drinking, physical activity, household income, oral health behavior, and use of anti-dyslipidemia medication. Our study suggests that the TG/HDL-C ratio is associated with periodontal disease in Korean adults. TG/HDL-C ratio is a simple and useful marker to reflect insulin resistance. And periodontal disease is also known to be related with insulin resistance. This study indicates that TG/HDL-C ratio was associated with periodontal disease in Korean adults.

Introduction The objective of this study was to investigate whether caffeine intake is associated with urinary incontinence (UI) and quality of life (QOL) in Korean postmenopausal women. Materials and Methods We included 4,028 postmenopausal women who had participated in the Korea National Health and Nutrition Examination Survey IV (KNHANES IV). From the KNHANES questionnaire data, we ascertained the UI status of participants, defined as self-reported or medically diagnosed UI, and calculated their total daily caffeine intake through questions regarding the frequency of food consumption. The EuroQoL-5 Dimension (EQ-5D) descriptive system was used to evaluate QOL among the study population. Results The mean age of the study population was 63.19±0.25 years. Among the 4,028 women, the prevalence of medically diagnosed UI was 2.6% (n = 151), the prevalence of self-reported UI was 11.9% (n = 483), and the lifetime prevalence of UI was 15.8% (n = 639). In the study population, the presence of UI was not significantly different by age group, but daily caffeine consumption and the percentage of caffeine consumer decreased with age (P<0.001). Higher caffeine intake led to significantly higher prevalence of both medically diagnosed UI (p = 0.012) and self-reported UI (p = 0.040) in the study population. Even after adjusting for factors including age, parity, smoking status, hypertension and diabetes in logistic regression analysis, the positive association between caffeine intake and UI prevalence was observed in both medically diagnosed UI and self-reported UI (P = 0.017) among participants. In a subgroup analysis for EQ-5D (using continuous variables) in which we categorized participants into four groups according to UI presence and caffeine consumption, the EQ-5D scores were lower in the caffeine non-user group with UI than in the caffeine consumer group with or without UI. Conclusion In a sample of Korean postmenopausal women, the prevalence of UI increased with higher caffeine consumption. Additionally, QOL was lower in caffeine non-users with UI than in the caffeine consumer groups. However, additional prospective studies are required to identify clear causation between caffeine consumption, UI prevalence and QOL. PMID:26901426

A Variational Echo Tracking (VET) technique has been applied to four months of archived data from the South Korean radar network in order to examine the influence of the various user-selectable parameters on the skill of the resulting 20-min to 4-h nowcasts. The latter are computed over a (512 × 512) array at 2-km resolution. After correcting the original algorithm to take into account the motion of precipitation across the boundaries of such a smaller radar network, we concluded that the set of default input parameters initially assumed is very close to the optimum combination. Decreasing to (5 sx 5) or increasing to (50 × 50) the default vector density of (25 × 25), using two or three maps for velocity determination, varying the relative weights for the constraints of conservation of reflectivity and of the smoothing of the velocity vectors, and finally the application of temporal smoothing all had only marginal effects on the skill of the forecasts. The relatively small sensitivity to significant variations of the VET default parameters is a direct consequence of the fact that the major source of the loss in forecast skill cannot be attributed to errors in the forecast motion, but to the unpredictable nature of the storm growth and decay. Changing the time interval between maps, from 20 to 10 minutes, and significantly increasing the reflectivity threshold from 15 to 30 dBZ had a more noticeable reduction on the forecast skill. Comparisons with the Eulerian "zero velocity" forecast and with a "single" vector forecast have also been performed in order to determine the accrued skill of the VET algorithm. Because of the extensive stratiform nature of the precipitation areas affecting the Korean peninsula, the increased skill is not as large as may have been anticipated. This can be explained by the greater extent of the precipitation systems relative to the size of the radar coverage domain.

Abstract Objectives Antiestrogen therapy can cause vasomotor symptoms similar to those occurring during menopause, including hot flashes. Recent studies suggest that acupuncture is effective in reducing vasomotor symptoms in patients with breast cancer receiving tamoxifen. The purpose of this study was to assess the feasibility and safety of acupuncture for treatment of hot flashes in Korean patients with breast cancer receiving antiestrogen therapy. Design This was a prospective single-arm observational study using before and after measurements. Settings/location The study was located at the East–West Medical Center at Daegu Catholic University Medical Center, Daegu, Korea. Subjects The subjects were 10 patients with breast cancer who were undergoing antiestrogen therapy with tamoxifen or anastrozole and who were suffering from hot flashes. Interventions Acupuncture was administered 3 times a week for 4 consecutive weeks, for 20±5 minutes at each session. Outcome measures The outcome measure was severity of hot flashes assessed by visual analogue scale (VAS) and total hot flash score. Results During treatment, severity of hot flashes was reduced by 70%–95% in all patients. Acupuncture significantly alleviated severity of hot flashes assessed by a visual analogue scale (F=30.261; p<0.001) as well as the total hot flash score (F=21.698; p=0.006). Four (4) weeks after the final treatment, symptoms were not aggravated. Conclusions Acupuncture appeared to provide effective relief from hot flashes among Korean women receiving antiestrogen therapy after surgery for breast cancer, and the effects lasted for at least 1 month after termination of treatment. A randomized controlled prospective study with a larger sample size is required to clarify the role of acupuncture in the management of hot flashes in Korean patients with breast cancer.

Purpose The Korean Society of Coloproctology holds its annual colorectal awareness month every September. This study analyzed the users and the contents of Korean tweets regarding colorectal cancer and estimated the transmissibility of the awareness campaign among Twitter users. Methods Prospective data collection was employed to accumulate Korean tweets containing the keywords "colorectal cancer," "colorectal cancer awareness campaign," "gold ribbon," and/or "love handle," from August 1 to September 30, 2014. Twitter users and contents were analyzed, and the credibility of information-sharing tweets throughout the study period was evaluated. Results In total, 10,387 tweets shared by 1,452 unique users were analyzed. As for users, 57.8% were individuals whereas 5.8% were organizations/communities; spambots accounted for a considerable percentage (36.4%). As for content, most tweets were spam (n = 8,736, 84.1%), repetitively advertising unverified commercial folk remedies, followed by tweets that shared information (n = 1,304, 12.6%) and non-information (n = 347, 3.3%). In the credibility assessment, only 80.6% of the information-sharing tweets were medically correct. After spam tweets had been excluded, a significant increase was seen in the percentage of information-sharing tweets (77.1% to 81.1%, P = 0.045) during the awareness campaign month. Conclusion Most Korean tweets regarding colorectal cancer during the study months were commercial spam tweets; informative public tweets accounted for an extremely small percentage. The transmissibility of the awareness campaign among Twitter users was questionable at best. To expand the reach of credible medical information on colorectal cancer, public health institutions and organizations must pay greater attention to social media. PMID:27847789

During the Pacific War (World War II), Japan maintained an elaborate system of sexual slavery by implementing certain practices based on institutionalized policies of hygiene, efficiency, and the use of mostly Korean girls and women. Two hygienic techniques were established--vaccination and quarantine. No. 606 injections were given at mandatory regularly scheduled medical examinations to prevent and treat venereal disease, and to also deter pregnancy, induce abortions, and ultimately sterilize sex slaves. Secondary textual analysis of data collected from 1995-2000, N = 67 interview transcripts, and participant observation in 2003 and 2006. Geographic area: East Asia and the Pacific Islands.

This study examined whether racial/ethnic differences in illness perceptions exist among patients on maintenance hemodialysis. One hundred sixty-one patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis (20% African Americans, 44% Hispanics, 9% Filipinos, and 27% Koreans) completed the Revised Illness Perception Questionnaire. Korean participants had higher emotional disturbance than their counterparts, whereas African-American participants had higher negative perceptions of personal intervention or medical treatment controlling their disease. This study indicates that patients from different racial/ethnic backgrounds undergoing maintenance hemodialysis may perceive their disease differently. This phenomenon could affect clinical outcomes and may require different therapeutic approaches. PMID:22480051

The quality of life (QoL) of patients with end-stage renal disease (ESRD) is very poor, plausibly due to both psychosocial and medical factors. This study aimed to determine the relationship among psychosocial factors, medical factors, and QoL in patients with ESRD undergoing hemodialysis (HD). In total, 55 male and 47 female patients were evaluated (mean age, 57.1 ± 12.0 years). The QoL was evaluated using the Korean version of World Health Organization Quality of Life Scale-Abbreviated Version. The psychosocial factors were evaluated using the Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support, Montreal Cognitive Assessment, Pittsburgh Sleep Quality Index, and Zarit Burden Interview. The medical factors were assessed using laboratory examinations. Correlation and canonical correlation analyses were performed to investigate the association patterns. The QoL was significantly correlated with the psychosocial factors, and to a lesser extent with the medical factors. The medical and psychosocial factors were also correlated. The canonical correlation analysis indicated a correlation between QoL and psychosocial factors (1st canonical correlation = 0.696, P < 0.001; 2nd canonical correlation = 0.421, P = 0.191), but not medical factors (1st canonical correlation = 0.478, P = 0.475; 2nd canonical correlation = 0.419, P = 0.751). The medical and psychosocial factors were also correlated (1st canonical correlation = 0.689, P < 0.001; 2nd canonical correlation = 0.603, P = 0.009). Psychosocial factors influence QoL in patients with ESRD, and should thus be carefully considered when caring for these patients in clinical practice. © 2018 The Korean Academy of Medical Sciences.

Treatment effectiveness holds considerable importance in the association between service quality and satisfaction in medical service studies. While complementary and alternative medicine (CAM) use grows more prominent, comprehensive evaluations of the quality of medical service at CAM-oriented hospitals are scarce. This study assesses the quality of medical services provided at a CAM-oriented hospital of Korean medicine using the service encounter system approach and analyzes the influence of treatment effectiveness on patient loyalty. A survey study using one-on-one interviews was conducted using a cross-sectional design in outpatients visiting one of fifteen Korean medicine facilities located throughout Korea. A total of 880 surveys were completed from June to July, 2014, and 728 surveys were included in the final analysis after excluding incomplete or incorrect questionnaires. The reliability and validity of the surveys was confirmed using Cronbach's alpha coefficient and confirmatory factor analysis, and a structural equation modeling analysis was performed to verify causality and association between factors (quality of medical service, treatment effectiveness, patient satisfaction, and intent to revisit). The measured factors of physician performance and quality of service procedures had a positive effect on treatment effectiveness. The impression of the facilities and environment directly impacted satisfaction rates for interpersonal-based medical service encounters, while treatment effectiveness positively affected satisfaction regarding quality of medical service. However, treatment effectiveness had a more significant effect on satisfaction compared to facilities and environment, and it indirectly affected satisfaction and directly influenced intent to revisit. Treatment effectiveness and satisfaction both positively influenced intent to revisit. The importance of treatment effectiveness should be recognized when examining quality of medical services, and we hope that these findings may contribute to future studies.

Primary dysmenorrhoea is menstrual pain without pelvic pathology and is the most common gynaecological condition in women. Xuefu Zhuyudecoction (XZD) or Hyeolbuchukeo-tang, a traditional herbal formula, has been used as a treatment for primary dysmenorrhoea. The purpose of this study is to assess the current published evidence regarding XZD as treatment for primary dysmenorrhoea. The following databases will be searched from their inception until April 2017: MEDLINE (via PubMed), Allied and Complementary Medicine Database (AMED), EMBASE, The Cochrane Library, six Korean medical databases (Korean Studies Information Service System, DBPia, Oriental Medicine Advanced Searching Integrated System, Research Information Service System, Korea Med and the Korean Traditional Knowledge Portal), three Chinese medical databases (China National Knowledge Infrastructure (CNKI), Wan Fang Database and Chinese Scientific Journals Database (VIP)) and one Japanese medical database (CiNii). Randomised clinical trials (RCTs) that will be included in this systematic review comprise those that used XZD or modified XZD. The control groups in the RCTs include no treatment, placebo, conventional medication or other treatments. Trials testing XZD as an adjunct to other treatments and studies where the control group received the same treatment as the intervention group will be also included. Data extraction and risk of bias assessments will be performed by two independent reviewers. The risk of bias will be assessed with the Cochrane risk of bias tool. All statistical analyses will be conducted using Review Manager software (RevMan V.5.3.0). This systematic review will be published in a peer-reviewed journal. The review will also be disseminated electronically and in print. The review will benefit patients and practitioners in the fields of traditional and conventional medicine.

As the need for the organ donation increases, strategies to increase kidney transplantation (KT) through expanded living donation have become essential. These include kidney paired donation (KPD) programs and desensitization in incompatible transplantations. KPD enables kidney transplant candidates with incompatible living donors to join a registry with other incompatible pairs in order to find potentially compatible living donor. Positive cross match and ABO incompatible transplantation has been successfully accomplished in selective cases with several pre-conditionings. Patients who are both difficult-to-match due to broad sensitization and hard-to-desensitize because of donor conditions can often be successfully transplanted through a combination of KPD and desensitization. According to the existing data, KPD can increase the number of KTs from living donors with excellent clinical results. This is also a cost-effective treatment as compared with dialysis and desensitization protocols. We carried out 3-way KPD transplantation with one highly sensitized, positive cross match pair and with two ABO incompatible pairs. Herein we report our first successful 3-way KPD transplantation in a single center. To maximize donor-recipient matching and minimize immunologic risk, KPD programs should use proper algorithms with desensitization to identify optimal donor with simultaneous two-, three- or more complex multi-way exchanges. © 2018 The Korean Academy of Medical Sciences.

The demand for autonomy in medical decision making is increasing among Korean people, but it is not well known why some people prefer autonomy in decision making but others do not. The aim of this study was to determine the extent to which Korean adults wished to exercise autonomy in the process of decision making regarding end-of-life treatment and to determine whether economic issues and family functioning, in particular, were associated with preferences for participation in decision making in Korean people. This study was a cross-sectional correlational study using a survey. Data were collected using structured questionnaires from 354 patients or their families who visited ambulatory departments at two general hospitals in South Korea, recruited by the proportionate quota sampling method. Data analysis was performed using multinomial logistic regression analyses. The study was approved by the hospitals' directors and the ethics committee of Kyungpook National University Hospital. Written informed consent was given by all participants. A majority of Korean people wanted to make autonomous decisions regarding treatment at the end of life. Preferences for autonomous decision making regarding end-of-life treatment, rather than relying on family, showed a significant increase in association with poor family functioning and low income. Results of this study suggested the necessity for development of alternatives to a dominant traditional "family-centered" approach in Korean people, in order to enhance end-of-life decision making for people who wish to take an active role in the decision-making process. Healthcare providers need to examine not only patients' preferred decision-making style but also any reasons for their choice, in particular, family conflict and financial burden. © The Author(s) 2014.

To determine the social and clinical characteristics of immigrants with tuberculosis (TB) in South Korea. The registered adult TB patients who were diagnosed and treated in Korea Medical Centers from January 2013 to December 2015 were analyzed retrospectively. A total of 105 immigrants with TB were compared to 932 native Korean TB patients. Among these 105 immigrants with TB, 86 (82%) were Korean-Chinese. The rate of drug-susceptible TB were lower in the immigrants group than in the native Korean group [odds ratio (OR): 0.46; 95% confidence interval (CI): 0.22-0.96, p=0.035]. Cure rate was higher in the immigrant group than in the native Korean group (OR: 2.03; 95% CI: 1.26-3.28, p=0.003). Treatment completion rate was lower in the immigrant group than in the native Korean group (OR: 0.50; 95% CI: 0.33-0.74, p=0.001). However, treatment success rate showed no significant difference between two groups (p=0.141). Lost to follow up (default) rate was higher in the immigrant group than in the native Korean group after adjusting for age and drug resistance (OR: 3.61; 95% CI: 1.36-9.61, p=0.010). There was no difference between defaulter and non-defaulter in clinical characteristics or types of visa among these immigrants (null p value). However, 43 TB patients with recent immigration were diagnosed as TB even though they had been screened as normal at the time of immigration. Endeavor to reduce the default rate of immigrants with TB and reinforce TB screening during the immigration process must be performed for TB infection control in South Korea. © Copyright: Yonsei University College of Medicine 2017

Difference in crude neonatal and infant mortality rates (NMR and IMR) among different countries is due to the differences in its two determinants: birth weight distribution (BWD) and birth weight-specific mortality rates (BW-SMRs). We aimed to determine impact of BWD and BW-SMRs on differences in crude NMR and IMR among Korea, Japan, and the U.S. Our study used the live birth data of the period 2009 through 2010. Crude NMR/IMR are the lowest in Japan, 1.1/2.1, compared to 1.8/3.2, in Korea, and 4.1/6.2, in the U.S., respectively. Japanese had the best BW-SMRs of all birth weight groups compared to the Koreans and the U.S. The U.S. BWD was unfavorable with very low birth weight (< 1,500 g) rate of 1.4%, compared to 0.6% in Korea, and 0.8% in Japan. If Koreans and Japanese had the same BWD as in the U.S., their crude NMR/IMR would be 3.9/6.1 for the Koreans and 1.5/2.5 for the Japanese. If both Koreans and Japanese had the same BW-SMRs as in the U.S., the crude NMR/IMR would be 2.0/3.8 for the Koreans and 2.7/5.0 for the Japanese. In conclusion, compared to the U.S., lower crude NMR or IMR in Japan is mainly attributable to its better BW-SMRs. Koreans had lower crude NMR and IMR, primarily from its favorable BWD. Comparing crude NMR or IMR among different countries should include further exploration of its two determinants, BW-SMRs reflecting medical care, and BWD reflecting socio-demographic conditions.

Since the mid-1990s, a growing number of North Korean defectors have been arriving in South Korea, many of whom have various somatic and mental disorders. The health status of defectors is an important predictor of their successful resettlement. Therefore, this study examined the frequency of physician visits among North Korean defectors residing in South Korea, as well as the factors associated with this frequency. The data used in this study were collected through survey questionnaires and interviews conducted from April 6 to May 20, 2009, and involving 500 North Korean defectors who entered South Korea in 2007. This study used three domains of independent variables: 'health-related factors,' 'special characteristics of North Korean defectors,' and 'demographic and socio-economic factors'. Nested multivariable linear regression analysis was conducted in order to determine the factors related to the frequency of physician visits between January 1 and December 31, 2008. The average number of physician visits made by the participants during 2008 was 15.3; 14.5% of participants did not have physician visits. The number of physician visits was largely associated with health-related variables including disability, chronic disease and self-rated health status. The frequency of physician visits was higher among those with a disability, chronic disease, lower self-rated health score, a greater number of traumatic experiences during their escape, lower annual family income, and among females. This study confirmed that the number of defectors' physician visits was related with objective and subjective health status, traumatic experiences during their migration, economic, and demographic variables. The results serve useful understanding of medical utilization characteristics among North Korean defectors in South Korea.

We review a new form of self-organizing map which is based on a nonlinear projection of latent points into data space, identical to that performed in the Generative Topographic Mapping (GTM).(1) But whereas the GTM is an extension of a mixture of experts, this model is an extension of a product of experts.(2) We show visualisation and clustering results on a data set composed of video data of lips uttering 5 Korean vowels. Finally we note that we may dispense with the probabilistic underpinnings of the product of experts and derive the same algorithm as a minimisation of mean squared error between the prototypes and the data. This leads us to suggest a new algorithm which incorporates local and global information in the clustering. Both ot the new algorithms achieve better results than the standard Self-Organizing Map.

Subsurface temperature plays an important role in determining heat contents in the upper ocean which are crucial in long-term and short-term weather systems. Furthermore, subsurface temperature affects significantly ocean ecology. In this study, a simple and practical algorithm has proposed. If we assume that subsurface temperature changes are proportional to surface heating or cooling, subsurface temperature at each depth (Sub_temp) can be estimated as follows PIC whereiis depth index, Clm_temp is temperature from climatology, dif0 is temperature difference between satellite and climatology in the surface, and ratio is ratio of temperature variability in each depth to surface temperature variability. Subsurface temperatures using this algorithm from climatology (WOA2013) and satellite SST (OSTIA) where calculated in the sea around Korean peninsula. Validation result with in-situ observation data show good agreement in the upper 50 m layer with RMSE (root mean square error) less than 2 K. The RMSE is smallest with less than 1 K in winter when surface mixed layer is thick, and largest with about 2~3 K in summer when surface mixed layer is shallow. The strong thermocline and large variability of the mixed layer depth might result in large RMSE in summer. Applying of mixed layer depth information for the algorithm may improve subsurface temperature estimation in summer. Spatial-temporal details on the improvement and its causes will be discussed.

We evaluated the effectiveness of a policy allowing for the sale of over-the-counter drugs outside of pharmacies by examining its effect on number of monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. We used medical claims data extracted from the Korean National Health Insurance Cohort Database from 2009 to 2013. The Korean National Health Insurance Cohort Database comprises a nationally representative sample of claims - about 2% of the entire population - obtained from the medical record data held by the Korean National Health Insurance Corporation (which has data on the entire nation). The analysis included26,284,706 person-months of 1,042,728 individuals. An interrupted-time series analysis was performed. Outcome measures were monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. To investigate the effect of the policy, we compared the number of monthly visits before and after the policy's implementation in 2012. For acute upper respiratory infections, monthly outpatient visits showed a decreasing trend before the policy (ß = -0.0003);after it, a prompt change and increasing trend in monthly outpatient visits were observed, but these were non-significant. For dyspepsia, the trend was increasing before implementation (ß = -0.0101), but this reversed after implementation(ß = -0.007). For migraine, an increasing trend was observed before the policy (ß = 0.0057). After it, we observed a significant prompt change (ß = -0.0314) but no significant trend. Deregulation of selling over-the-counter medication outside of pharmacies reduced monthly outpatient visits for dyspepsia and migraine symptoms, but not acute upper respiratory infections.

Objectives The Korean government has enacted two laws, namely, the Personal Information Protection Act and the Bioethics and Safety Act to prevent the unauthorized use of medical information. To protect patients' privacy by complying with governmental regulations and improve the convenience of research, Asan Medical Center has been developing a de-identification system for biomedical research. Methods We reviewed Korean regulations to define the scope of the de-identification methods and well-known previous biomedical research platforms to extract the functionalities of the systems. Based on these review results, we implemented necessary programs based on the Asan Medical Center Information System framework which was built using the Microsoft. NET Framework and C#. Results The developed de-identification system comprises three main components: a de-identification tool, a search tool, and a chart review tool. The de-identification tool can substitute a randomly assigned research ID for a hospital patient ID, remove the identifiers in the structured format, and mask them in the unstructured format, i.e., texts. This tool achieved 98.14% precision and 97.39% recall for 6,520 clinical notes. The search tool can find the number of patients which satisfies given search criteria. The chart review tool can provide de-identified patient's clinical data for review purposes. Conclusions We found that a clinical data warehouse was essential for successful implementation of the de-identification system, and this system should be tightly linked to an electronic Institutional Review Board system for easy operation of honest brokers. Additionally, we found that a secure cloud environment could be adopted to protect patients' privacy more thoroughly. PMID:23882415

Military medical advances resulting from the conflict in Korea, Part I: Systems advances that enhanced patient survival.

Baker, Michael S

2012-04-01

The Korean War started several years after the World War II had ended and no recognition of the threat or preparation was made for this possibility. The military and its medical service had been downsized after World War II and had to quickly ramp up to meet the surprise attack. The war provided the laboratory for trials and experimentation with the new technological developments of the era. The Korean conflict led to numerous advances in medical systems and patient care. The Mobile Army Surgical Hospital came of age, and was instrumental in saving many lives. Helicopters saw their first regular use as flying ambulances to take the injured to definitive care in a timely fashion. The national blood banking program was rapidly geared up and new techniques such as plastic bags for collection and delivery resulted. Body armor was developed that would allow mobility while offering protection and was widely used for the first time. Each of these systems improvements saved the lives of soldiers in combat and were soon to be used in the civilian sector to save and improve lives around the world.

Performance of universal health insurance: lessons from South Korea.

The aim of this study was to assess the maturity of the South Korean healthcare system in comparison with those of the 30 countries of the Organization for Economic Co-operation and Development (OECD) and to provide a foundation to evaluate the performance of the South Korean healthcare system. Using OECD Health Data 2005, we evaluated the performance of the healthcare system of the 30 industrialized countries. The evaluation focused on three dimensions that have remained central to healthcare debates internationally for years: access, cost and outcomes. Although South Korea has successfully implemented its universal health insurance scheme in a very short period of time and possesses highly advanced medical technologies, we found that South Koreans incurred more out-of-pocket expenditures on healthcare. Health outcomes were of relatively low quality compared with those of other OECD countries, but compared relatively well with the four countries (Greece, New Zealand, Portugal and Spain) with similar per capita gross domestic product (GDP).

This study aimed to explore the effectiveness of logo-autobiography (LA) as a therapeutic modality for Korean immigrant women suffering from depression and perceiving their lives as meaningless. A nonrandomized quasi-experimental study was conducted with pretest, posttest, and a 4-week follow-up test. Forty subjects--20 with antidepressants and 20 without--were divided quarterly and assigned to the experimental group and the control group. The experimental group reported a significant lower score on depressive symptoms (F = 6.832, p = .013; F = 19.800, p ≤ .001) and a higher score on meaning of life (F = 12.294, p = .001; F = 12.232, p = .001) than did the control group immediately after completing the LA and a 4-week follow-up. The LA was more effective for the subjects in the nonmedication group than in the medication group. In conclusion, LA is effective in reducing depressive symptoms and increasing a sense of meaning in life among Korean immigrant women suffering from depression.

2018-01-01

Lack of depression literacy is associated with low help-seeking behaviors for mental health care in adolescents. As parents generally determine adolescents' health care, ensuring parents can recognize depressive symptoms is crucial. The current study explored depression literacy among Korean American parents of adolescents ages 12 to 19 using a qualitative descriptive design. Semantic content analysis was performed using data from three focus group interviews conducted in 2015 with Korean American parents (10 mothers, four fathers) of adolescents. Participants lacked knowledge about the biological causes and medicinal treatment of depression. Most believed that depression cannot be fully treated, relapses occur easily, and medication is taken indefinitely. Gender influenced perceptions of symptoms. Parents often overlooked children's depressive symptoms until schools alerted them. Nursing interventions should educate parents about the biological causes of depression, strategies for addressing adolescents' symptoms, community-based professional resources, and success stories about depression treatment.

The Korean National Tuberculosis Association (KNTA) set up the Korean Institute of Tuberculosis (KIT) in 1970 to foster research and technical activities pertaining to tuberculosis (TB). The KNTA/KIT had successfully conducted a countrywide TB prevalence survey from 1965 to 1995 at 5-year intervals. The survey results (decline in TB rates) established Korea as a country that had successfully implemented national control programs for TB. The KIT developed the Korea Tuberculosis Surveillance System and the Laboratory Management Information System, both of which were transferred to the Korea Centers for Disease Control and Prevention after its establishment. The KIT functions as a central and supranational reference TB laboratory for microbiological and epidemiological research and provides training and education for health-care workers and medical practitioners. Recently, the KIT has expanded its activities to countries such as Ethiopia, Laos, and Timor-Leste to support TB control and prevention. The KIT will continue to support research activities and provide technical assistance in diagnosing the infection until it is completely eliminated in Korea. PMID:25861580

Knowing one's interpersonal relationship preferences can be tremendously helpful for medical students' lives. The purpose of this study was to examine the interpersonal needs in medical students. Between 2010 and 2015, a total of 877 students from four Korean medical schools took the Korean version of the Fundamental Interpersonal Relations Orientation - Behaviour (FIRO-B) scale. The FIRO-B results were analyzed by descriptive statistics, frequency, independent t-test, and one-way ANOVA. The medical students' scores for interpersonal needs were moderate overall, with the highest scores for control (M = 8.63, SD = 3.08), followed by affection (M = 8.14, SD = 4.34), and inclusion (M = 7.81, SD = 4.30). Gender differences showed in three areas: expressed control (male > female, t = 4.137, p < 0.001), wanted affection (male < female, t = -3.148, p = 0.002), and control needs (male > female, t = 2.761, p = 0.006). By school type, differences were shown in expressed control (t = 3.581, p < 0.001), wanted inclusion (t = 2.625, p = 0.009), Inclusion (t = 1.966, p = 0.050), and expressed (t = 2.077, p = 0.038); undergraduate medical college (MC) students' needs were greater than the needs of graduate medical school (MS) students, but for wanted control, the MS students showed greater needs (t = -2.122, p = 0.034). There were differences in all categories except for expressed inclusion, wanted control, and control. The FIRO-B is a useful tool for giving insight into students regarding their interpersonal orientations, which will help them to adjust to medical school life. In addition, the FIRO-B can be useful when mentoring and coaching students.

A novel clinical decision support algorithm for constructing complete medication histories.

PubMed

Long, Ju; Yuan, Michael Juntao

2017-07-01

A patient's complete medication history is a crucial element for physicians to develop a full understanding of the patient's medical conditions and treatment options. However, due to the fragmented nature of medical data, this process can be very time-consuming and often impossible for physicians to construct a complete medication history for complex patients. In this paper, we describe an accurate, computationally efficient and scalable algorithm to construct a medication history timeline. The algorithm is developed and validated based on 1 million random prescription records from a large national prescription data aggregator. Our evaluation shows that the algorithm can be scaled horizontally on-demand, making it suitable for future delivery in a cloud-computing environment. We also propose that this cloud-based medication history computation algorithm could be integrated into Electronic Medical Records, enabling informed clinical decision-making at the point of care.

[Establishment and activity of PoKuNyoKwan].

PubMed

Lee, Bang Weon

2008-06-01

PoKuNyoKwan was established in 1887 by Meta Howard, a female doctor who was dispatched from Woman's Foreign Missionary Society, an evangelical branch affiliated with U.S. North Methodist Church. PoKuNyoKwan was equipped with dispensaries, waiting rooms, pharmacies, warehouses, operating rooms, and wards for about 30 patients. It used a traditional Korean house, which was renovated for its medical purpose, in Ewha Haktang. Residing in Chung Dong, the medical institution had taken care of women's mental and physical health for about 25 years, until it was merged with East Gate Lillian Harris Memorial Hospital in 1912, and then its dispensary function was abolished in 1913. Medical missionaries (Meta Howard, Rosetta Sherwood, Mary M. Cutler, Emma Ernsberger, Esther K. Pak, Amanda F. Hillman) and nurse missionaries (Ella Lewis, Margaret J. Edmunds, Alta I. Morrison, Naomi A. Anderson), who were professionally trained in the United States, and their helpers, who were trained by those missionaries, managed PoKuNyoKwan. Nurses who were educated in Nurses' Training School, which was also established by PoKuNyoKwan, helped to run the institution as well. At the beginning, they usually had worked as a team of one medical missionary and three helpers. Since its establishment in 1903, however, the helpers began to enter the Nurses' Training School to become professional nurses, and the helpers eventually faded out because of the proliferation of those nurses. PoKuNyoKwan did not only offer medical services but also executed educational and evangelical activities. Medical missionaries struggled to overcome Koreans' ignorance and prejudice against westerners and western medical services, while they took care of their patients at office, for calls, and in hospital dispensaries. Enlightening the public by criticizing Korean traditional medical treatments including fork remedies, acupuncture, and superstitions, they helped modernization of medical systems in Korea. In the area of education, Rosetta Sherwood taught helpers basic medical science to make them regular medical staff members, and Margaret J. Edmunds established the Nurses' Training School in PoKuNyoKwan for the first time in Korea. The nurses who graduated from the school worked at PoKuNyoKwan and some other medical institutions. Evangelical activities included Bible study in the waiting rooms of PoKuNyoKwan and prayer meeting on Sunday for those who were treated in PoKuNyoKwan. The institution in the end worked as a spot for spreading Christianity in Korea. As the first women's hospital, PoKuNyoKwan attempted to educate female doctors. Eventually, it played a role as a cradle to produce Esther K Pak, who was the first female doctor in Korea. The hospital also ran the first nurse training center. It was, in a real sense, the foundational institution to raise professional practitioner undertaking medical services in Korea. Therefore, it is reasonable to say that PoKuNyoKwan provided sound basis for the development of modem medical services for women in Korea.

The Differences in Health Care Utilization between Medical Aid and Health Insurance: A Longitudinal Study Using Propensity Score Matching

2015-01-01

Study Objectives Health care utilization has progressively increased, especially among Medical Aid beneficiaries in South Korea. The Medical Aid classifies beneficiaries into two categories, type 1 and 2, on the basis of being incapable (those under 18 or over 65 years of age, or disabled) or capable of working, respectively. Medical Aid has a high possibility for health care utilization due to high coverage level. In South Korea, the national health insurance (NHI) achieved very short time to establish coverage for the entire Korean population. However there there remaine a number of problems to be solved. Therefore, the objective of this study was to investigate the differences in health care utilization between Medical Aid beneficiaries and Health Insurance beneficiaries. Methods & Design Data were collected from the Korean Welfare Panel Study from 2008 to 2012 using propensity score matching. Of the 2,316 research subjects, 579 had Medical Aid and 1,737 had health insurance. We also analyzed three dependent variables: days spent in the hospital, number of outpatient visits, and hospitalizations per year. Analysis of variance and longitudinal data analysis were used. Results The number of outpatient visits was 1.431 times higher (p<0.0001) in Medical Aid beneficiaries, the number of hospitalizations per year was 1.604 times higher (p<0.0001) in Medical Aid beneficiaries, and the number of days spent in the hospital per year was 1.282 times higher (p<0.268) for Medical Aid beneficiaries than in individuals with Health Insurance. Medical Aid patients had a 0.874 times lower frequency of having an unmet needs due to economic barrier (95% confidence interval: 0.662-1.156). Conclusions Health insurance coverage has an impact on health care utilization. More health care utilization among Medical Aid beneficiaries appears to have a high possibility of a moral hazard risk under the Health Insurance program. Therefore, the moral hazard for Medical Aid beneficiaries should be avoided. PMID:25816234

Script-independent text line segmentation in freestyle handwritten documents.

Text line segmentation in freestyle handwritten documents remains an open document analysis problem. Curvilinear text lines and small gaps between neighboring text lines present a challenge to algorithms developed for machine printed or hand-printed documents. In this paper, we propose a novel approach based on density estimation and a state-of-the-art image segmentation technique, the level set method. From an input document image, we estimate a probability map, where each element represents the probability that the underlying pixel belongs to a text line. The level set method is then exploited to determine the boundary of neighboring text lines by evolving an initial estimate. Unlike connected component based methods ( [1], [2] for example), the proposed algorithm does not use any script-specific knowledge. Extensive quantitative experiments on freestyle handwritten documents with diverse scripts, such as Arabic, Chinese, Korean, and Hindi, demonstrate that our algorithm consistently outperforms previous methods [1]-[3]. Further experiments show the proposed algorithm is robust to scale change, rotation, and noise.

Han Chinese, Japanese and Korean, the three major ethnic groups of East Asia, share many similarities in appearance, language and culture etc., but their genetic relationships, divergence times and subsequent genetic exchanges have not been well studied. We conducted a genome-wide study and evaluated the population structure of 182 Han Chinese, 90 Japanese and 100 Korean individuals, together with the data of 630 individuals representing 8 populations wordwide. Our analyses revealed that Han Chinese, Japanese and Korean populations have distinct genetic makeup and can be well distinguished based on either the genome wide data or a panel of ancestry informative markers (AIMs). Their genetic structure corresponds well to their geographical distributions, indicating geographical isolation played a critical role in driving population differentiation in East Asia. The most recent common ancestor of the three populations was dated back to 3000 ~ 3600 years ago. Our analyses also revealed substantial admixture within the three populations which occurred subsequent to initial splits, and distinct gene introgression from surrounding populations, of which northern ancestral component is dominant. These estimations and findings facilitate to understanding population history and mechanism of human genetic diversity in East Asia, and have implications for both evolutionary and medical studies.

To examine a psychoeducational intervention's effects on knowledge and attitudes toward antipsychotic medication in clients with schizophrenia and schizoaffective disorders. A one-group pretest-posttest design was employed. A convenience sample (61 psychiatric clients aged 20 or above) was recruited from a Korean mental health center. At baseline, participants had limited knowledge (M = 50.89, range: 27-77, SD = 12.05) of and negative feelings toward antipsychotic medications (M = -.89, range: -8 to 8, SD = 4.27). Both measures significantly improved post-intervention. A psychoeducational intervention improved clients' knowledge of and attitudes toward antipsychotic medications. © 2015 Wiley Periodicals, Inc.

Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp. sebastian.deorowicz@polsl.pl, iochoa@stanford.edu Supplementary data are available at Bioinformatics online. © The Author 2015.

Validation of an arterial tortuosity measure with application to hypertension collection of clinical hypertensive patients

PubMed Central

2011-01-01

Background Hypertension may increase tortuosity or twistedness of arteries. We applied a centerline extraction algorithm and tortuosity metric to magnetic resonance angiography (MRA) brain images to quantitatively measure the tortuosity of arterial vessel centerlines. The most commonly used arterial tortuosity measure is the distance factor metric (DFM). This study tested a DFM based measurement’s ability to detect increases in arterial tortuosity of hypertensives using existing images. Existing images presented challenges such as different resolutions which may affect the tortuosity measurement, different depths of the area imaged, and different artifacts of imaging that require filtering. Methods The stability and accuracy of alternative centerline algorithms was validated in numerically generated models and test brain MRA data. Existing images were gathered from previous studies and clinical medical systems by manually reading electronic medical records to identify hypertensives and negatives. Images of different resolutions were interpolated to similar resolutions. Arterial tortuosity in MRA images was measured from a DFM curve and tested on numerically generated models as well as MRA images from two hypertensive and three negative control populations. Comparisons were made between different resolutions, different filters, hypertensives versus negatives, and different negative controls. Results In tests using numerical models of a simple helix, the measured tortuosity increased as expected with more tightly coiled helices. Interpolation reduced resolution-dependent differences in measured tortuosity. The Korean hypertensive population had significantly higher arterial tortuosity than its corresponding negative control population across multiple arteries. In addition one negative control population of different ethnicity had significantly less arterial tortuosity than the other two. Conclusions Tortuosity can be compared between images of different resolutions by interpolating from lower to higher resolutions. Use of a universal negative control was not possible in this study. The method described here detected elevated arterial tortuosity in a hypertensive population compared to the negative control population and can be used to study this relation in other populations.

Psychiatry in Korea.

Park, Jong-Il; Oh, Keun-Young; Chung, Young-Chul

2013-04-01

This paper reports the current status of Korean psychiatry. In 2011, there were 3005 psychiatrists and 75,000 psychiatric beds. There were 84 psychiatric residency-training hospitals in 2011, which produced about 150 psychiatry board-certified doctors annually. As for academic activity, there is the Korean Neuropsychiatric Association, a main association for neuropsychiatry, and 21 other research societies. Psychiatric residency is a 4-year training program, with different objectives for each grade. The Korean health system accepts National Health Insurance. When severely mentally ill patients register as having a mental disorder, they pay only 10% of their total medical costs. Private clinics usually see patients with less severe conditions such as anxiety, mood and eating disorders; general and university hospitals and special mental hospitals often deal with severe conditions such as schizophrenia and bipolar disorder. One great concern is an increasing trend to depend upon pharmacotherapy and neglect the role of psychotherapy. Additionally, conflicts among medical sectors are becoming fierce as other doctors request abolition of the current law that restricts them from prescribing anti-depressants for more than 60 days. The average hospitalization period of all mental care institutions was 166 days in 2010, substantially longer compared with developed countries. To win the heart of the general public, cutting edge research to improve the quality of treatment for mental diseases, reformation of psychiatric residency training programs, public campaigns to increase awareness of mental health value, and timely reflection on policy decisions should be pursued persistently.

Lee, Jinkook; Smith, James P.

2013-01-01

Background Undiagnosed disease is one of the critical public health problems in the world. In 2002 South Korean introduced the nation’s first comprehensive public health promotion policy, Health Plan 2010. The first phase of Health Plan 2010 started in 2002, promoting early detection of diseases and preventative care and continued until 2005. Methods Using the 2001 and 2005 Korean National Health and Nutrition Examination Surveys that were fielded before and after the health promotion program, we investigate changes in health care utilization and its impacts on the prevalence of diagnosed and undiagnosed diabetes as well as the good management of the disease. Results A significant rise in diabetes diagnoses has occurred during this time period, especially for those with low education and older age. We find that, during this time period, the prevalence of undiagnosed diabetes was significantly reduced especially among older and less educated Koreans, the principal targets of the program. We also find that this health promotion had significant positive effects on good management of diabetes. Conclusions The increase of preventative health care through medical check-up among less-educated, older people suggests that the implementation of free medical check-ups for age 40 and older may have a positive impact on those who had not previously used preventative care. The positive experience in South Korea indicates that similarly designed public health campaigns in other countries have enormous potential in improving the detection and management of chronic disease.

Functional dyspepsia (FD) is the seventh most common disease encountered in Korean medicine (KM) clinics. Despite the large number of FD patients visiting KM clinics, the accumulated medical records have no utility in evidence development, due to being unstructured. This study aimed to construct a standard operating procedure (SOP) with appropriate structured diagnostic methods for FD, and assess the feasibility for use in KM clinics. Two rounds of professional surveys were conducted by 10 Korean internal medicine professors to select the representative diagnostic methods. A feasibility study was conducted to evaluate compliance and time required for using the structured diagnostic methods by three specialists in two hospitals. As per the results of the professional survey, five questionnaires and one basic diagnostic method were selected. An SOP was constructed based on the survey results, and a feasibility study showed that the SOP compliance score (out of 5) was 3.45 among the subjects, and 3.25 among the practitioners. The SOP was acceptable and was not deemed difficult to execute. The total execution time was 136.5 minutes, out of which the gastric emptying test time was 129 minutes. This feasibility study of the SOP with structured diagnostic methods for FD confirmed it was adequate for use in KM clinics. It is expected that these study findings will be helpful to clinicians who wish to conduct observational studies as well as to generate quantitative medical records to facilitate Big Data research.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition that adversely affects men across a wide range of ages. A number of pharmacologic and nonpharmacologic therapies for CP/CPPS have been investigated. Our study aimed to evaluate the prevalence of CPPS in Korean men in their thirties and to investigate the effect of CPPS and medical treatment on semen quality. Of 314 men with prostatitis, 74 patients with CPPS class IIIA (23.6%) were eligible for the study; these patients underwent combined α-blocker and cyclo-oxygenase 2 inhibitor therapy. These 74 men were prospectively studied at a medical center in Seoul, Korea. A number of parameters, including ejaculations per month, semen variables, and the levels of hormones (such as follicle-stimulating hormone, estradiol [E(2)], luteinizing hormone [LH], testosterone, and prolactin) were evaluated. The mean number of ejaculations per month, the mean number of daily hours spent sitting at work, smoking, body mass index, LH and E(2) levels, and semen parameters all showed significant differences (P < .0001) between the study patients and the controls. The combined regimen was effective in improving all aspects of semen quality except morphology (P < .05). CPPS class IIIA, which is notably prevalent among Korean men in the fourth decade of life, affects semen quality and poses a challenge to fertility. Proper treatment of CPPS class IIIA results in improved semen quality. Men with CPPS therefore require proper evaluation and treatment by andrologists/urologists before planning a natural conception.

Medical laboratories play a central role in health care. Many laboratories are taking a more focused and stringent approach to quality system management. In Korea, laboratory standardization efforts undertaken by the Korean Laboratory Accreditation Program (KLAP) and the Korean External Quality Assessment Scheme (KEQAS) may have facilitated an improvement in laboratory performance, but there are no fundamental studies demonstrating that laboratory standardization is effective. We analyzed the results of the KEQAS to identify significant differences between laboratories with or without KLAP and to determine the impact of laboratory standardization on the accuracy of diagnostic tests. We analyzed KEQAS participant data on clinical chemistry tests such as albumin, ALT, AST, and glucose from 2010 to 2013. As a statistical parameter to assess performance bias between laboratories, we compared 4-yr variance index score (VIS) between the two groups with or without KLAP. Compared with the group without KLAP, the group with KLAP exhibited significantly lower geometric means of 4-yr VIS for all clinical chemistry tests (P<0.0001); this difference justified a high level of confidence in standardized services provided by accredited laboratories. Confidence intervals for the mean of each test in the two groups (accredited and non-accredited) did not overlap, suggesting that the means of the groups are significantly different. These results confirmed that practice standardization is strongly associated with the accuracy of test results. Our study emphasizes the necessity of establishing a system for standardization of diagnostic testing. © The Korean Society for Laboratory Medicine

Since 2002, the number of marriages, births, and family members among multi-cultural families (MCFs) has increased. Beginning in 2006, the government initiated a planned management for such families and has implemented the MCF policy basic plan since 2010. In 2015, with multiple socio-economic and medical support initiatives for MCF being available, we analyzed the statistics for several factors related to birth, to determine whether there are significant adverse birth outcomes in MCF. We analyzed the birth data of MCFs in 2015, from Statistics Korea. This study compared the birth data of MCF and Korean families (KF) by geography, neonatal birth weight (BW), gestational age (GA), birth order of the neonates, place of delivery, cohabitation period of parents before the first child, and parental education level. The distribution of BW and the prevalence of low BW (< 2,500 g) or very low BW (< 1,500 g) were similar between both groups. The incidence of preterm birth was lower in the MCF group (6.5% vs. 7.0%, P = 0.015) than in the KF group. In the MCF group, parental education level was lower, and incidence of out-of-hospital births was higher than that of the KF group. Adverse birth outcomes, such as preterm birth and low BW in MCF are similar or better than KF. This study could be a good basis to present the status of MCF birth and newborn care in 2015. © 2017 The Korean Academy of Medical Sciences.

Colorectal cancer (CRC) remains the most commonly diagnosed cancer among Korean Americans (KAs) in part due to low screening rates. Recent studies suggest that some KA patients engage in medical tourism and receive medical care in their home country. The impact of medical tourism on CRC screening is unknown. The purpose of this paper was to 1) investigate the frequency of medical tourism, 2) examine the association between medical tourism and CRC screening, and 3) characterize KA patients who engage in medical tourism. This is a community-based, cross-sectional study involving self-administered questionnaires conducted from August 2013 to October 2013. Data was collected on 193 KA patients, ages 50-75, residing in the Seattle metropolitan area. The outcome variable is up-to-date with CRC screening, defined as having had a stool test (Fecal Occult Blood Test or Fecal Immunochemical Test) within the past year or a colonoscopy within 10 years. Predictor variables are socio-demographics, health factors, acculturation, knowledge, financial concerns for medical care costs, and medical tourism. In multi-variate modeling, medical tourism was significantly related to being up-to-date with CRC screening. Participants who engaged in medical tourism had 8.91 (95% CI: 3.89-23.89) greater odds of being up-to-date with CRC screening compared to those who did not travel for healthcare. Factors associated with engaging in medical tourism were lack of insurance coverage (P = 0.008), higher levels of education (P = 0.003), not having a usual place of care (P = 0.002), older age at immigration (P = 0.009), shorter years-of-stay in the US (P = 0.003), and being less likely to speak English well (P = 0.03). This study identifies the impact of medical tourism on CRC screening and characteristics of KA patients who report engaging in medical tourism. Healthcare providers in the US should be aware of the customary nature of medical tourism among KAs and consider assessing medical tests done abroad when providing cancer care. Not applicable.

The aims of this study were to estimate the prevalence of mental-physical comorbidity and health-threatening risk factors in subjects with mental disorders, and the risks of mental disorders in those with physical diseases for the last 12 months in the general Korean population. Korean Epidemiologic Catchment Area study replication (KECA-R) was conducted for 6,510 adults between August 2006 and April 2007. The Korean version of Composite International Diagnostic Interview 2.1 (K-CIDI) was used in the survey. Prevalence of mental and physical disorders, and risk factors for physical health were calculated, and their associations were evaluated with adjustment for age and sex. Subjects with any mental disorder showed significantly higher prevalence of chronic physical conditions (adjusted odds ratio, AOR=1.5 to 2.8, p<0.001) and medical risk factors including smoking, heavy drinking, overweight, and hypertension (AOR=1.5 to 4.0, p<0.001). Of those with chronic physical conditions, 21.6% had one or more comorbid mental disorder compared with 10.5% of the subjects without chronic physical disorders (AOR=2.6, p<0.001). Contrary to expectations, depressive disorders did not show significant association with hypertension and prevalence of obesity was not influenced by presence of mental disorders. Further studies should assess these findings. This is the first identification of significant mental-physical comorbidity in the general Korean population. Clinicians and health care officials should keep in mind of its potential adverse effects on treatment outcome and aggravated disease-related socioeconomic burden.

To investigate nurses' opinions and practices of providing information in a global context through cultural comparison. Providing sufficient information to patients about nursing interventions and plans is essential for patient-centred care. While many countries have specific legislation making information delivery to patients a legal duty of nurses, no such legislation exists in both the Republic of Korea and Italy; nurses' only guidance is the deontological code. This was a cross-sectional survey study involving a convenience sample of 174 Korean nurses and 121 Italian nurses working in internal medicine and surgery at university hospitals. Data were collected using a self-administered questionnaire between February and November 2014. The questionnaire assessed demographic and professional characteristics, and difficulties and practices regarding information provision. Korean and Italian nurses significantly differed in all demographic and professional characteristics. More Korean than Italian participants reported that their role in providing information was well explained within their teams, but both groups reported the same level and type of difficulties in delivering information. Nurses in both countries regularly informed patients about medications and nursing procedures, but provided information about nursing care plans less frequently. Few nurses frequently provided information to relatives instead of patients. Despite cultural, demographic and professional differences between Korean and Italian nurses, their difficulties and practices in information delivery to patient were similar. Hospital managers and policymakers should be aware that nurse-patient communication can be impaired by organizational factors, patient characteristics or the interaction among providers. Educational interventions and strategies are needed to increase information provision to patients about nursing care plans. © 2017 International Council of Nurses.

To examine the abilities of HbA1c and fasting plasma glucose (FPG) criteria predicting 5-year progression rate to diabetes in Korean adults with prediabetes. Participants included 17,971 Koreans (aged 20-79years) who underwent routine medical check-ups at a mean interval of 5.2years (3.1-6.7years). Prediabetes was defined as FPG 5.6-6.9mmol/l or HbA1c 5.7-6.4% (39-46mmol/mol). Incident diabetes was defined as FPG⩾7.0mmol/l, HbA1c⩾6.5% (48mmol/mol), or initiation of antidiabetic medications. At baseline, the prevalence of prediabetes was 30.6% (n=5495) by FPG and 20.4% (n=3664) by HbA1c criteria. The 5-year progression rate to diabetes was significantly higher in prediabetes identified by HbA1c than by FPG tests (14.7% vs. 10.4%, P<0.001). Of individuals diagnosed with prediabetes by only one test, those by HbA1c alone had a higher risk of progression to diabetes than those diagnosed by FPG alone (6.0% vs. 3.9%, P<0.001). Receiver operating characteristic curve analysis showed that area under the curve was greater for HbA1c (0.855, 95% CI 0.840-0.870) than for FPG (0.830, 0.813-0.846) (P=0.016). After adjustment for conventional risk factors, the odds ratio (OR) of developing diabetes was higher in participants with prediabetes identified by HbA1c (OR 9.91, 8.24-11.9) than by FPG (OR 7.29, 5.97-8.89) (P=0.026). Although fewer individuals with prediabetes were identified by HbA1c than by FPG criteria, the ability to predict progression to diabetes was stronger for HbA1c than for FPG in Koreans.

The South Korean government recently developed a master plan for establishing a national trauma system based on the implementation of regional trauma centers. We aimed to compare outcomes between severely injured patients treated at a recently established South Korean trauma center and matched patients treated in American level-1 trauma centers. Two cohorts were selected from an institutional trauma database at Ajou University Medical Center (AUMC) and the American National Trauma Data Bank. Adult patients with an Injury Severity Score of ≥9 were included. Patients were matched based on covariates that affect mortality, using 1:1 propensity score matching. We compared outcomes between the two datasets and performed survival analyses. We created 1,451 and 2,103 matched pairs for the pre-trauma center and post-trauma center periods, respectively. The in-hospital mortality rate was higher in the institutional trauma database pre-trauma center period compared with the American National Trauma Data Bank (11.6% versus 8.1%, P<.001). However, the mortality rate decreased in the institutional trauma database post-trauma center period and was similar to that in the American National Trauma Data Bank (6.9% versus 6.8%, P=.903). Being treated at Ajou University Medical Center Trauma Center was significantly associated with higher mortality during the pre-trauma center period (OR: 1.842, 95% CI: 1.336-2.540; P<.001), although no significant association was observed during the post-trauma center period (OR: 1.102, 95% CI: 0.827-1.468; P=.509). The mortality rate improved after a trauma center was established in a South Korean hospital and is similar to that from matched cases treated at American level-1 trauma centers. Thus, creating trauma centers and a regional trauma system may improve outcomes in major trauma cases. Copyright © 2018 Elsevier Inc. All rights reserved.

Parecoxib is an injectable cyclooxygenase-2 inhibitor with proven postoperative analgesic efficacy in a variety of settings, including total knee arthroplasty (TKA). The effect of ethnicity on the efficacy of parecoxib for post-TKA pain has not been studied. This was a parallel-group, double-blind, randomized, placebo- controlled study of ethnically Korean patients aged ≥18 years who had unilateral TKA. Patients who reported moderate or severe pain 6 hours after the end of postoperative opioid analgesia were randomized to receive a single intravenous dose of parecoxib sodium 40 mg or placebo. Patients were evaluated for 24 hours postdose. The primary efficacy endpoints included time-specific pain intensity difference (PID), time-specific pain relief (PR), and time to rescue medication. The incidence and nature of adverse events (AEs) assessed safety. Of the 116 patients randomized, 58 received parecoxib and 58 placebo. Mean (SD) PID was significantly greater for parecoxib vs placebo 1 hour postdose (0.69 [0.67] vs 0.40 [0.59], respectively; p <0.05), and for each time point up to 24 hours. Similarly, mean (SD) PR was significantly greater for parecoxib vs placebo 1.5 hours postdose (1.63 [0.85] vs 1.07 [0.90], respectively; p =0.001), and for each time point up to 24 hours. The median time (hours:minutes) to rescue medication was significantly longer for parecoxib vs placebo (21:30 vs 4:08, respectively; p <0.001). Generally, fewer AEs were reported with parecoxib than placebo, and the AE profile was consistent with previous studies. These results are comparable to the findings from a similarly designed study in a Caucasian patient population. Parecoxib 40 mg significantly improved postoperative pain vs placebo in Korean patients after TKA. The efficacy and safety of parecoxib in Korean patients is similar to that seen in Caucasian patients.

In Korea, patients with terminal cancer are often caught out of the loop in end-of-life (EoL) care discussions. Healthcare professionals also have difficulty engaging in such communication in a variety of healthcare contexts. Therefore, the objective of our study was to develop a communication model for EoL care decision making compatible with the clinical environment in Korea. Using focus-group interview methodology, participants included eight doctors and five nurses who provide EoL care for terminal cancer patients in acute hospital settings or hospice care facilities in various provinces of Korea. Five themes emerged regarding EoL care discussion, which included: (1) timing, (2) responsible professionals, (3) disclosure of bad news, (4) content areas of EoL care discussion, and (5) implementing strategies for EoL care discussions. These themes were based on development of a communication algorithm for EoL discussion among patients with terminal cancer. A structural communication step for delivery of a terminal prognosis was specified at the phase of disclosure of bad news: beginning with determination of a patient's decision-making capability, followed by a patient's perception of his/her condition, a patient's wish to know, family dynamics, and a patient's and/or family's readiness for EoL discussions. The proposed context-oriented communication algorithm could provide a helpful guideline for EoL communication and, accordingly, facilitate meaningful improvements in EoL care in Korean clinical practice. The feasibility of this algorithm has not yet been determined, and its validation in a larger sample of patients with terminal cancers, using a quantitative research methodology, is a priority of research.

Objectives This study was designed to investigate changes in health-related quality of life (HRQoL) of patients with acromegaly in Korea after medical treatment with octreotide LAR using the validated Korean version of the acromegaly quality of life questionnaire (AcroQoL). Design A prospective, open-label, single-arm study. Setting 11 tertiary centres in Korea. Participants 58 Korean patients (aged 21–72 years) who were newly diagnosed with acromegaly between 2009 and 2012 were prescribed octreotide LAR 20 mg at the time of enrolment. During 24 weeks of observation, AcroQoL survey questionnaires and measurement of growth hormone insulin-like growth factor 1(GH/IGF-I) were performed at baseline, week 12 and week 24. Main outcome measures We assessed the HRQoL of Korean patients with acromegaly after medical treatment with octreotide LAR using the validated Korean version of the AcroQoL questionnaire. Results Patients had a mean age of 47.2 years (29 males), and GH and IGF-I significantly decreased during the first 12 weeks (GH: 4.8 vs 1.9 μg/L, p<0.001; IGF-I: 497 vs 265 μg/L, p<0.001), but showed insignificant change at week 24 (GH: 2.3 μg/L; IGF-I: 294 μg/L). Only AcroQoL scores for the psychological appearance subdomain showed a significant increase during the entire 24 weeks (p<0.05). The change in the psychological appearance subdomain of AcroQoL scores demonstrated a significant but weak negative correlation with change in IGF-I levels (r=−0.282, p=0.039). When patients were divided into two groups according to their disease activity at week 24 (controlled vs uncontrolled), there was no difference in AcroQoL scores, but the psychological appearance subdomain of the two groups appeared to change differently over the entire 24-week period (p=0.047). Conclusions: Medical treatment with octreotide LAR in patients with acromegaly has a limited contribution to HRQoL as assessed by the AcroQoL. PMID:26063564

Colon cancer screening is being introduced in many countries, but standard Western screening approaches may not be appropriate for Asian societies if differences in colon cancer epidemiology exist. Comparative analysis of colorectal neoplasia patterns in South Korean and Western subjects has implications for appropriate screening approaches in non-Western societies. The results of concurrent screening colonoscopies performed in average-risk patients 50 to 69 years old in 2 teaching hospitals, Kyung Hee University Hospital (Seoul, South Korea) and Virginia Mason Medical Center (Seattle, Wash), were compared with respect to prevalence, histologic features, anatomic distribution, and shape characteristics of colorectal neoplasia. The U.S. (n = 3460) and South Korean (n = 2193) cohorts were similar with regard to the prevalence of adenomas (28.5% vs 29.8%, respectively, P = .312) and advanced neoplasia (6.4% vs 5.4%, respectively, P = .102), but the proportion of proximal adenomas was greater in the U.S. cohort (62.8% vs 45.9%, P < .001). The prevalence of adenomas and advanced neoplasia was similar in male patients, but there was a greater prevalence of neoplasia (23.5% vs 18.8%, P = .006) and advanced neoplasia (5.1% vs 2.7%, P < .001) in U.S. women than South Korean women. When large (≥10 mm) adenomas were considered, proximal location and nonpolypoid (flat) shape were more common in the U.S. cohort (79.4% vs 37.1%, P = .003 and 43.5% vs 12.3%, P < .001, respectively). The overall prevalence of large flat adenomas in the U.S. cohort was 5 times that of the South Korean cohort (2.6% vs 0.5%, P < .001). Adjustment for sex ratio discrepancies (48.3% men in the U.S. cohort vs 60.8% in the South Korean cohort, P < .001) did not result in any significant changes in the conclusions. Compared with Westerners, South Koreans have a more distal distribution of adenomas and advanced neoplasia and lower prevalence of large flat adenomas. South Korean women have a lower prevalence of colorectal neoplasia than Western women. Such disparities suggest that Western screening strategies cannot be directly adopted by other countries, but need to be customized by society.

[The influence of the devotion movement on the health care in North Korea].

Choi, Young-In; Kim, Soo-Youn; Hwang, Sang-Ik

2006-06-01

Since the early 1960s, North Korea has conducted 'devotion movement' under the directorship of Kim Il Sung across the nation. As a matter of fact, the movement was not a novel invention at all. When North Korean Temporary People's Polity was established in 1946, North Korea emphasized the importance of the devoted care of health personnel. It meant to reform the people's thought and mind along with complementing the lack of human and material resources. Thought reform was not a peculiar phenomenon observed in North Korea only. It was particularly stressed out among communist countries, including the Soviet Union. However any other communist country stresses the importance of thought reform. Devotion movement should be viewed as part of this process. As shown in many cases, the extent and degree of devotion movement and care are beyond our imagination, which does not intend to mean that North Korean health personnel's attitude towards patients is superior to the counterparts in South Korea. Indeed human being's behavior cannot be understood without taking account of society in general. The question can be raised as to whether or not North Korean health personnel's devoted care is really voluntary. To put aside the testimony that the most powerless group in a society can fall prey to victims, if social environment, whether directly or indirectly, is action on the people's thought and mind even in a subtle way and thus influence one's decision power, it is hard to highly evaluate the devoted care in North Korea. Moreover it seems like that the internal conflict exists surrounding devotion. In conclusion, I think that North Korean devotion movement has enforced health personnel to reform their thought and mind to adapt to North Korean regime and has played an important role to accomplish the purpose of North Korean Labor Party to realize essential constituents of its health system, in such a situation in which essential medical supplies are severely lacking. But it seems like that it plays reverse action to develope sound North Korean health system.

Usual source of care (USC) is one of the hallmarks of primary care. We aimed to examine the status of having a USC and its patient-related sociodemographic factors among Korean adults. Data were obtained from the 2012 Korea Health Panel survey. Panel participants were selected for the study who were aged 18 years or older and who replied to questionnaire items on having a USC (n = 11,935). Of the participants, 21.5% had a usual place and 13.9% had a usual physician. Reasons for not having a USC were seldom being ill (66.1%), the preference to visit multiple medical institutions (27.9%), and others. The private community clinic was the most common type of usual place (57.0%). In patient-reported attributes of care provided by a usual physician, the percentages of positive responses for comprehensiveness and coordination were 67.2% and 34.5%, respectively. By institution type, primary care clinics showed the lowest percentage (32.8%) of positive responses for coordination. Adjusted odds ratios of having a usual physician were 3.77 (95% confidence interval, CI: 3.75-3.79) for those aged 65 years or older (vs. aged 18-34 years), 1.31 (CI: 1.30-1.31) for females (vs. males), 0.72 (CI: 0.72-0.73) for unmarried people (vs. married), 1.16 (CI: 1.16-1.16) for college graduates or higher (vs. elementary school graduate or less), 0.64 for the fifth quintile (vs. the first quintile) by household income, 1.53 (CI: 1.52-1.54) for Medical Aid (vs. employee health insurance) for type of health insurance, and 4.09 (CI: 4.08-4.10) for presence (vs. absence) of a chronic diseases. The proportion of Korean adults who have a USC is extremely low, the most influential factor of having a USC is having a chronic disease or not, and Korean patients experience much poorer health care coordination than do patients in other industrialized countries. The findings of this study will give insight to researchers and policy makers regarding the potential facilitators of and barriers to promoting having a USC in the general Korean public.

The purpose of this study is to examine and explain the extent of income-related inequity in health care utilization and expenditures to compare the extent in 2005 and 2010 in Korea. We employed the concentration indices and the horizontal inequity index proposed by Wagstaff and van Doorslaer based on one- and two-part models. This study was conducted using data from the 2005 and 2010 Korean National Health and Nutrition Examination Survey. We examined health care utilization and expenditures for different types of health care providers, including health centers, physician clinics, hospitals, general hospitals, dental care, and licensed traditional medical practitioners. The results show the equitable distribution of overall health care utilization with pro-poor tendencies and modest pro-rich inequity in the amount of medical expenditures in 2010. For the decomposition analysis, non-need variables such as income, education, private insurance, and occupational status have contributed considerably to pro-rich inequality in health care over the period between 2005 and 2010. We found that health care utilization in Korea in 2010 was fairly equitable, but the poor still have some barriers to accessing primary care and continuing to receive medical care.

Health systems are increasingly implementing remote telephone and Internet refill systems to enhance patient access to medication refills. Remote refill systems may provide an effective approach for improving medication non-adherence, but more research is needed among patients with limited English proficiency with poor access to remote refill systems. To compare the use of remote medication refill systems among limited-English-proficiency (LEP) and English-proficient (EP) patients with chronic conditions. Cross-sectional survey in six languages/dialects (English, Cantonese, Mandarin, Korean, Vietnamese, and Spanish) of 509 adults with diabetes, hypertension, or hyperlipidemia. Primary study outcomes were self-reported use of 1) Internet refills, 2) telephone refills, and 3) any remote refill system. LEP was measured by patient self-identification of a primary language other than English and a claims record of use of an interpreter. Other measures were age, gender, education, years in the U.S., insurance, health status, chronic conditions, and number of prescribed medications. Analyses included multivariable logistic regression weighted for survey non-response. Overall, 33.1 % of patients refilled their medications by telephone and 31.6 % by Internet. Among LEP patients (n = 328), 31.5 % refilled by telephone and 21.2 % by Internet, compared with 36.7 % by telephone and 52.7 % by Internet among EP patients (n = 181). Internet refill by language groups were as follows: English (52.7 %), Cantonese (34.9 %), Mandarin (17.4 %), Korean (16.7 %), Vietnamese (24.4 %), and Spanish (12.6 %). Compared to EP patients, LEP patients had lower use of any remote refill system (adjusted odds ratio [AOR] 0.18; p < 0.001), CONCLUSIONS: LEP patients are significantly less likely than EP patients to use any remote medication refill system. Increased reliance on current systems for remote medication refills may increase disparities in health outcomes affecting LEP patients with poor access to telephone and Internet medication refills.

Considering that large variations exist amongst practitioners in lumbar disorder management and the significant costs that lumbar disorders incur, determining clinical practice patterns to provide preliminary data for standardization should be given higher priority. Lumbar spinal stenosis (LSS) is commonly treated using integrative non-surgical methods by Korean medicine doctors (KMDs) in Korea, and this is the first study to assess current Korean medicine practice trends for LSS. A survey on KMD diagnosis, treatment, prognosis and decision-making in LSS treatment was developed in a 3-step procedure of preliminary drafting, revision based on extramural expert opinion, and final editing. The survey was conducted at the internal conference of a spine-specialty Korean medicine hospital on January 25th, 2015. The response rate was high at 79.19% (n = 118/149). Participants replied that they treated 7.3 ± 6.8 LSS patients/day using a multimodal treatment method consisting of acupuncture, pharmacopuncture, herbal medicine, Chuna manipulation, and electroacupuncture. Acupuncture mainly used Ashi points and MSAT, and pharmacopuncture mainly Shinbaro solution. The most frequently prescribed herbal medicine was Chungpa-jun, and the most commonly applied Chuna techniques were sidelying lumbar extension dysfunction correction technique, and prone lumbosacral joint distraction method. Radiological findings were mainly referred to for diagnosis, and clinical symptoms, age, radiological findings, and medical history were regarded to be important for prognosis. Participants replied that 7.8 ± 3.3 weeks were required for 50% reduction in pain, and 16.1 ± 7.7 weeks for 80% reduction. These results suggest that KMDs in Korea combine a conventional approach to LSS and a Korean medicine approach to low back pain for integration of empirical- and evidence-based diagnosis and treatment. The findings may contribute in bridging the divide between evidence and clinical practice guidelines for Korean medicine treatment of LSS and real-world clinical practice in future research.

Previous reports mostly from Europe suggested an association between an occurrence of narcolepsy and an influenza A(H1N1)pdm09 vaccine adjuvanted with AS03 (Pandemrix(®)). During the 2009 H1N1 pandemic vaccination campaign, the Korean military performed a vaccination campaign with one type of influenza vaccine containing MF59-adjuvants. This study was conducted to investigate the background incidence rate of narcolepsy in South Korean soldiers and the association of the MF59-adjuvanted vaccine with the occurrence of narcolepsy in a young adult group. To assess the incidence of narcolepsy, we retrospectively reviewed medical records of suspicious cases of narcolepsy in 2007-2013 in the whole 20 military hospitals of the Korean military. The screened cases were classified according to the Brighton Collaboration case definition of narcolepsy. After obtaining the number of confirmed cases of narcolepsy per 3 months in 2007-2013, we compared the crude incidence rate of narcolepsy before and after the vaccination campaign. We included 218 narcolepsy suspicious cases in the initial review, which were screened by the diagnostic code on the computerized disease registry in 2007-2013. Forty-one cases were finally diagnosed with narcolepsy in 2007-2013 (male sex, 95%; median age, 21 years). The average background incidence rate of narcolepsy in Korean soldiers was 0.91 cases per 100,000 persons per year. During the 9 months before vaccination implementation (April to December 2009), 6 narcolepsy cases occurred, whereas during the next 9 months (January to September 2010) including the 3-month vaccination campaign, 5 cases occurred. The incidence of narcolepsy in South Korean soldiers was not increased after the pandemic vaccination campaign using the MF59-adjuvanted vaccine. Our results suggest that the MF59-adjuvanted H1N1 vaccine did not contribute to the occurrence of narcolepsy in this young adult group. Copyright © 2015 Elsevier Ltd. All rights reserved.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by a relapsing and remitting course. The direct and indirect costs of the treatment of UC are high, and the quality of life of patients is reduced, especially during exacerbation of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies, including biologics, are currently used for the management of UC. However, many challenging issues exist, which sometimes lead to differences in practice between clinicians. Therefore, the IBD study group of the Korean Association for the Study of Intestinal Diseases established the first Korean guidelines for the management of UC in 2012. This is an update of the first guidelines. It was generally made by the adaptation of several foreign guidelines as was the first edition, and encompasses treatment of active colitis, maintenance of remission, and indication of surgery for UC. The specific recommendations are presented with the quality of evidence and classification of recommendations. PMID:28239313

The temperament and character of korean male conscripts with military maladjustment-a preliminary study.

Recently, an increasing number of Korean male conscripts have been retiring because of military maladjustment despite the presence of qualifying medical and psychological screening tests in the Korean army. These problems suggest the presence of a common personality problem. To further examine this possibility, the present study used Cloninger's psychobiological model to investigate the temperament and character of soldiers suffering from military maladjustment. Seventy-nine maladjusted male conscripts and eighty-seven controls enrolled at the 1596th unit from April 2011 to June 2012 participated in the present study. To measure participant personality, we used the Korean version of the Temperament and Character Inventory, Revised-Short. We used logistic regression analysis to examine the association between TCI-RS scores and risk of military maladjustment. The maladjustment group had a lower rank, socioeconomic status, education level, and a shorter duration of military service than the control group. The harm avoidance and self-transcendence scores were significantly higher in the maladjustment group, with lower scores for reward dependence, persistence, self-directedness, and cooperativeness scores. However, of these measures, only low cooperativeness was associated with an increased risk of military maladjustment. These results suggest that a low level of cooperativeness can predict military inadequacy. Maladjusted male conscripts may have different personality characteristics from normals. To validate our results, further follow-up or cohort studies with a larger sample will be required.

Excessive oral salt intake can induce hypertension. According to previous studies, the prevalence of hypertension is higher in Myanmar than in Korea. We postulated that Myanmar adults had higher salt taste thresholds and eat much saltier food. This study aimed to compare salt taste thresholds and salt usage behaviour scores between adults in Myanmar and Korea. This cross-sectional study enrolled patients who visited volunteer medical service clinics at Ansung in Korea and Hlegu and Bago in Myanmar in August 2014. We measured the vital signs, heights, and weights of each patient and evaluated detection thresholds, recognition thresholds, and salt preferences. All patients underwent urinalysis and spot urine Na tests. Additionally, they each completed a salt usage behaviour questionnaire. A total of 131 patients were enrolled, including 64 Myanmarese patients and 67 Korean patients. Blood pressure was significantly higher in the Myanmarese than in the Koreans. Detection and recognition thresholds, salt preferences, and spot urine sodium and salt usage behaviour scores were also higher in the Myanmarese than in the Korean subjects. We calculated correlation coefficients between systolic blood pressure and parameters that were related to salt intake. The detection and recognition thresholds were significantly correlated with systolic blood pressure. All parameters related to salt intake, including detection and recognition thresholds, salt preference, salt usage behaviour scores and spot urine sodium concentrations, are significantly higher in Myanmarese than in Korean individuals.

Purpose Since 1996, the Korean Breast Cancer Society has collected nation-wide breast cancer data and analyzed the data using their online registration program biannually. The purpose of this study was to evaluate the characteristics of Korean breast cancer from 2008 and examine chronological based patterns. Methods Data were collected from 38 medical schools (67 hospitals), 20 general hospitals, and 10 private clinics. The data on the total number, gender, and age distribution were collected through a questionnaire as well as other detailed data analyzed via the online registration program. Results In 2008, there were 13,908 patients who were newly diagnosed with breast cancer. The crude incidence rate of female breast cancer was 57.3 among 100,000 and the median age was 49 years. The age distribution had not changed since the initial survey; however the proportion of postmenopausal patients had increased and median age was older than the past. In staging distribution, the proportion of early breast cancer (stage 0, I) was 47.2% with, breast-conserving surgery performed in 58% and mastectomy in 39.5%. Conclusion Compared to past data, the incidence of breast cancer in Korea continues to rise. Furthermore, the proportion of those detected by screening and breast conservation surgery has increased remarkably. To understand the patterns of Korean breast cancer, the nation-wide data should continuously investigated. PMID:22031806

The aim of this study was to investigate autism spectrum disorder (ASD) clinical practice patterns of Korean medicine doctors (KMDs) through questionnaire survey. Questionnaires on Korean medicine (KM) treatment for ASD were distributed to 255 KMDs on December 5, 2016. The KMDs were psychiatrists, pediatricians, or general practitioners, who treated patients with ASD. The questionnaire covered items on treatment methods, aims of treatment, KM syndrome differentiation, diagnostic tools, and sociodemographic characteristics. Frequency analysis was conducted to describe the participants and their practices. A total 22.4% KMDs (n = 57/255) completed the questionnaires and 54 KMDs (21.2%) matched the inclusion criteria. The KMDs utilized herbal medicine (27.3%), body acupuncture (17.6%), scalp acupuncture (10.7%), moxibustion (6.4%), and Korean medical psychotherapy (5.9%) to treat ASD. The most commonly prescribed herbal medicine was Yukmijihwang-tang. Forty-eight (88.9%) KMDs responded that they used KM syndrome differentiation. 'Organ system, Qi, Blood, Yin, Yang, Fluid and Humor diagnosis' was most frequently used for syndrome differentiation. ASD was mainly diagnosed based on the fourth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) and DSM-5. The present study demonstrated the current status of KMDs' diagnosis and treatment of ASD. In future clinical trials and clinical practice guidelines, these findings will provide meaningful information on the actual practice patterns of KMDs.

Past decades of division have led to substantial differences in medical environments between South and North Korea. However, little is known about North Korea's medical status and research field, especially regarding endocrinology. In this study, we report the characteristics of North Korea's articles regarding endocrine-related diseases. Among the nine medical journals, articles published in Internal Medicine between 2006 and 2015 were reviewed. A total of 2,092 articles were included; among them, 96 articles were associated with endocrinology. We analyzed these articles according to the disease categories they focused on and evaluated their features. Articles related to diabetes mellitus accounted for 55.2% (n=53) and those to thyroid disease accounted for 28.1% (n=27). Other disease categories, including adrenal gland (n=1), pituitary gland (n=1), and osteoporosis (n=3), comprised minor portions. Regarding diabetes mellitus, more than half the articles (n=33) focused on treatment and complications. Experimental studies were conducted with old hypoglycemic drugs or natural substances for the treatment of hyperglycemia. Regarding thyroid disease, articles related to hyperthyroidism were the most common (51.9%, n=14), followed by thyroid nodule/cancer (18.5%, n=5). Unique article features were short length, no figures, and less than five references. North Korea's endocrinology articles mainly focused on diabetes mellitus and thyroid disease. Persistent studies have been carried out in North Korea with dedication despite the poor medical environment. We hope that this study will be the beginning of mutual medical exchange and collaboration between North and South Korea. Copyright © 2018 Korean Endocrine Society.

The Relationship between Senior Year Examinations at a Medical School and the Korean Medical Licensing Examination.

2009-03-01

Most medical schools prepare for the Korean medical licensing examination (KMLE) with various tests. By assessing the degree to which these exams and the KMLE are related, students, professors, and institutions can be well prepared and some schools use these exams as predictive tools for KMLE scores. Therefore, we determined the relevance of KMLE results to midterm exams and the objective structured clinical examination (OSCE), administered to senior students at a medical school. From 2002 to 2004, KMLE results were compared with midterm examinations, the KMLE, and the OSCE. The total score, or T-score, of the KMLE was used, as was a pass or nonpass score. Windows SPSS 14.0 and MedCalc 9.0 were used for statistical analysis. The yearly correlation coefficient of the KMLE and school exams was highest for the midterm exams in 2002 and the KMLE in 2003 and 2004. The correlation coefficient of midterm exams and the KMLE were related to a high degree, yet the values were as low as that of the OSCE. Compared with the KMLE results, the sensitivity and specificity of the average midterm exam were 100.0% and 93.8%, and the sensitivity and specificity of the average trial exams were 100.0% and 95.8%, respectively. In conclusion, the KMLE results have a strong relationship with midterm exams, trial exams, and the combination of midterm and trial exams, but not with the OSCE. Thus, we believe that using both midterm exams and trial exams to predict KMLE results is superior to the use of only one type of school exam.

An antiseptic religion: discovering a hybridity on the flux of hygiene and Christianity.

PubMed

Kim, Shin K

2008-06-01

An antiseptic religion is a form of Protestant Christianity that was shaped in the context of colonization in Korea. This term was coined to explain a religious hybrid that was produced by the intermingling of American Evangelical Protestant Christianity, the concept of hygiene (germ theory) and indigenous Korean religiosity. This research deals with a historical process of making 'a medicalized religion' in Asia from a perspective of postcolonialism. Most of the early American Protestant missionaries in Korea were medical doctors who were influenced by the Germ theory of illness and considered Western medicine as an efficient tool to evangelize the country. As a result of their mission, a religious culture which emphasized washing away sins from the soul as analogous to washing away germs from the body was born. In addition, the Korean people developed a very unique form of public bathing ritual centered in the development of public baths to alleviate anxiety and to destabilize the solid strategies of the Japanese and the Americans, the two major colonial powers in Korea's history in the late 19th century.

A rapid development of practice of laboratory medicine in Korea owes its success to the clinical pathologists (CP), who have played a role of a pathfinder for laboratories. The Korean CP postgraduate education (residency) program is unique in that it is exclusively for laboratory medicine. The training program for clinical pathologists includes diagnostic hematology, diagnostic immunology, clinical microbiology, clinical chemistry, blood bank, diagnostic genetics, informatics and laboratory management. The program has produced a strong group of about 600 laboratory physicians, officially clinical pathologists since 1963. Most of Korean clinical pathologists work as laboratory directors, directors of university hospital laboratories or teaching faculty members in medical schools. The roles of clinical pathologists are laboratory management, interpretation of laboratory test results, clinical consulting services to clinicians and patients, ordering secondary tests after reviews of requested test results and utilization management. The clinical pathologists have developed clinical laboratories to be a main contributor for improved medical practice. During the last 40 years under the turbulent healthcare system, clinical pathologists have significantly contributed to safeguard the laboratory interests. The education program and the role of clinical pathologists are described.

Standardization of medical terminology is essential in data transmission between health care institutes and in maximizing the benefits of information technology. The purpose of this study was to standardize medical terms for laboratory observations. During the second year of the study, a standard database of concept names for laboratory terms that covered those used in tertiary health care institutes and reference laboratories was developed. The laboratory terms in the Logical Observation Identifier Names and Codes (LOINC) database were adopted and matched with the electronic data interchange (EDI) codes in Korea. A public hearing and a workshop for clinical pathologists were held to collect the opinions of experts. The Korean standard laboratory terminology database containing six axial concept names, components, property, time aspect, system (specimen), scale type, and method type, was established for 29,340 test observations. Short names and mapping tables for EDI codes and UMLS were added. Synonym tables were prepared to help match concept names to common terms used in the fields. We herein described the Korean standard laboratory terminology database for test names, result description terms, and result units encompassing most of the laboratory tests in Korea. PMID:18756062

Iridology is the study of the iris of the eye to detect the conditions of the body and its organs, genetic strengths and weaknesses, etc. Although iridology is not widely used as a scientific tool for healthcare professionals to get to the source of people's health conditions, it has been used as a supplementary source to help the diagnosis of medical conditions by noting irregularities of the pigmentation in the iris among some Korean Oriental medical doctors. Angiotensin converting enzyme (ACE) gene polymorphism is one of the most well studied genetic markers of vascular disease. We investigated the relationship between iridological constitution and ACE polymorphism in hypertensives. We classified 87 hypertensives and 79 controls according to iris constitution and determined the ACE genotype of each individual. DD genotype was more prevalent in patients with a neurogenic constitution than in controls. This finding supports the hypothesis that D allele is a candidate gene for hypertension and demonstrates the association among ACE genotype, Korean hypertensives and iris constitution.

The objective of the study was to develop, implement and evaluate two treatment algorithms for schizophrenia and depression at a psychiatric hospital department. The treatment algorithms were based on available literature and developed in collaboration between psychiatrists, clinical pharmacologists and a clinical pharmacist. The treatment algorithms were introduced at a meeting for all psychiatrists, reinforced by the project psychiatrists in the daily routine and used for educational purposes of young doctors and medical students. A quantitative pre-post evaluation was conducted using data from medical charts, and qualitative information was collected by interviews. In general, no significant differences were found when comparing outcomes from 104 charts from the baseline period with 96 charts from the post-intervention period. Most of the patients (65% in the post-intervention period) admitted during the data collection periods did not receive any medication changes. Of the patients undergoing medication changes in the post-intervention period, 56% followed the algorithms, and 70% of the patients admitted to the psychiatric hospital department for the first time had their medications changed according to the algorithms. All of the 10 interviewed doctors found the algorithms useful. The treatment algorithms were successfully implemented with a high degree of satisfaction among the interviewed doctors. The majority of patients admitted to the psychiatric hospital department for the first time had their medications changed according to the algorithms.

The purpose of the study was to evaluate vision-related quality of life in Korean glaucoma patients and to explore the associated factors. A total of 907 glaucoma patients were recruited from the prospectively designed LIGHT (Life quality of the glaucoma patient who underwent treatment) study organized by the Korean Glaucoma Society. Basic questionnaire that included items related to socioeconomic status, comorbidity, and lifestyle, and the validated Korean version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) were collected. The Rasch score, a logit-based interval scale estimate to summarizing the NEI VFQ-25 responses, was calculated. The univariate and multivariable regression models were used to evaluate associations between the Rasch score and variables. The mean patient age was 58.1±14.1 years, visual field mean deviation (VF MD) of the better and worse eyes was -4.92±6.14 and -9.77±8.31 dB, binocular-integrated VF (IVF) MD was -3.55±5.31 dB, respectively. The lower NEI VFQ-25 Rasch score showed a significant association with the presence of other ocular diseases (P=0.020), a high school level of education or less [vs. university (P=0.006), vs. graduate school or higher (P=0.019)], an anxious personality [vs. a moderate personality (P<0.001), vs. a relaxed personality (P<0.001)], the number of glaucoma medications in use (P=0.049), worse eye visual acuity (P<0.001), and IVF MD (P<0.001). Visual function parameters are important for the vision-related quality of life of Korean glaucoma patients, notably for worse eye visual acuity and IVF MD. However, social factors, self-assessed personality, and treatment-related issues are also substantial predictors of overall life quality.

Group B streptococcus (GBS) infection is a leading cause of sepsis and meningitis among infants, and is associated with high rates of morbidity and mortality in many countries. Protection against GBS typically involves antibody-mediated opsonization by phagocytes and complement components. The present study evaluated serotype-specific functional antibodies to GBS among Korean infants and in intravenous immunoglobulin (IVIG) products. An opsonophagocytic killing assay (OPA) was used to calculate the opsonization indices (OIs) of functional antibodies to serotypes Ia, Ib, and III in 19 IVIG products from 5 international manufacturers and among 98 Korean infants (age: 0-11 months). The GBS Ia, Ib, and III serotypes were selected because they are included in a trivalent GBS vaccine formulation that is being developed. The OI values for the IVIG products were 635-5,706 (serotype Ia), 488-1,421 (serotype Ib), and 962-3,315 (serotype III), and none of the IVIG lots exhibited undetectable OI values (< 4). The geometric mean OI values were similar for all 3 serotypes when we compared the Korean manufacturers. The seropositive rate among infants was significantly lower for serotype Ia (18.4%), compared to serotype Ib and serotype III (both, 38.8%). Infant age of ≥ 3 months was positively correlated with the seropositive rates for each serotype. Therefore, only a limited proportion of infants exhibited protective immunity against serotype Ia, Ib, and III GBS infections. IVIG products that exhibit high antibody titers may be a useful therapeutic or preventive measure for infants. Further studies are needed to evaluate additional serotypes and age groups. © 2017 The Korean Academy of Medical Sciences.

Although the concern about coffee-associated health problems is increasing, the effect of coffee on osteoporosis is still conflicting. This study aimed to determine the relationship between coffee consumption and bone health in Korean postmenopausal women. A population-based, cross-sectional study was performed using a nationally representative sample of the Korean general population. All 4,066 postmenopausal women (mean age 62.6 years) from the fourth and fifth Korean National Health and Nutrition Examination Survey (2008-2011), who completed the questionnaire about coffee consumption and had data of dual-energy X-ray absorptiometry (DXA) examination. Bone mineral density (BMD) was measured using DXA at the femoral neck and lumbar spine and osteoporosis was defined by World Health Organization T-score criteria in addition to self-report of current anti-osteoporotic medication use. After adjusting for various demographic and lifestyle confounders (including hormonal factors), subjects in the highest quartile of coffee intake had 36% lower odds for osteoporosis compared to those in the lowest quartile (Adjusted odds ratio [aOR] = 0.64; 95% confidence interval [CI], 0.43-0.95; P for trend = 0.015). This trend was consistent in osteoporosis of lumbar spine and femoral neck (aOR = 0.65 and 0.55; P for trend = 0.026 and 0.003, respectively). In addition, age- and body mass index (BMI)-adjusted BMD of the femoral neck and lumbar spine increased with higher coffee intake (P for trend = 0.019 and 0.051, respectively). Coffee consumption may have protective benefits on bone health in Korean postmenopausal women in moderate amount. Further, prospective studies are required to confirm this association.

The present study explored the relationships between fried food consumption and metabolic risk factors and hypertension in Korean adults. The study was based on the fifth Korean National Health and Nutrition Examination Survey between 2010 and 2011. A total of 9221 Korean adults aged ≥19 years were studied. Fried food consumption was assessed using a validated FFQ. Metabolic risk factors such as waist circumference, fasting plasma glucose (FPG), TAG, HDL-cholesterol and systolic and diastolic blood pressure (SBP and DBP) were measured. Hypertension was defined as SBP≥140 mmHg, DBP≥90 mmHg or current use of antihypertensive medication. Adjusted OR for elevated blood pressure significantly increased in men (OR 1·62; 95% CI 1·11, 2·37; P(trend)=0·0447) and women (OR 2·20; 95% CI 1·21, 4·00; P(trend)=0·0403) with a greater than twice a week consumption of fried food compared with those who rarely consumed fried food. However, fried food consumption was not associated with other metabolic risk factors (abdominal obesity, high FPG, hypertriacylglycerolaemia, low HDL-cholesterol and the metabolic syndrome). The adjusted OR for hypertension increased by 2·4-fold in women (OR 2·37; 95% CI 1·19, 4·72; P(trend)=0·0272) with a greater than twice a week fried food consumption compared with those who rarely consumed it. No significant association was found between fried food consumption and hypertension in men. This study suggests that frequent fried food consumption is associated with hypertension in Korean women. Further studies are needed to investigate the effect of different types of fried foods on hypertension.

Sleep problems commonly occur in patients with Parkinson's disease (PD), and are associated with a lower quality of life. The aim of the current study was to translate the English version of the Scales for Outcomes in Parkinson's Disease-Sleep (SCOPA-S) into the Korean version of SCOPA-S (K-SCOPA-S), and to evaluate its reliability and validity for use by Korean-speaking patients with PD. In total, 136 patients with PD from 27 movement disorder centres of university-affiliated hospitals in Korea were enrolled in this study. They were assessed using SCOPA, Hoehn and Yahr Scale (HYS), Unified Parkinson's Disease Rating Scale (UPDRS), Parkinson's Disease Sleep Scale 2nd version (PDSS-2), Non-motor Symptoms Scale (NMSS), Montgomery Asberg Depression Scale (MADS), 39-item Parkinson's Disease Questionnaire (PDQ39), Neurogenic Orthostatic Hypotension Questionnaire (NOHQ), and Rapid Eye Movement Sleep Behaviour Disorder Questionnaire (RBDQ). The test-retest reliability was assessed over a time interval of 10-14 days. The internal consistency (Cronbach's α-coefficients) of K-SCOPA-S was 0.88 for nighttime sleep (NS) and 0.75 for daytime sleepiness (DS). Test-retest reliability was 0.88 and 0.85 for the NS and DS, respectively. There was a moderate correlation between the NS sub-score and PDSS-2 total score. The NS and DS sub-scores of K-SCOPA-S were correlated with motor scale such as HYS, and non-motor scales such as UPDRS I, UPDRS II, MADS, NMSS, PDQ39, and NOHQ while the DS sub-score was with RBDQ. The K-SCOPA-S exhibited good reliability and validity for the assessment of sleep problems in the Korean patients with PD. © 2018 The Korean Academy of Medical Sciences.

Genome data are becoming increasingly important for modern medicine. As the rate of increase in DNA sequencing outstrips the rate of increase in disk storage capacity, the storage and data transferring of large genome data are becoming important concerns for biomedical researchers. We propose a two-pass lossless genome compression algorithm, which highlights the synthesis of complementary contextual models, to improve the compression performance. The proposed framework could handle genome compression with and without reference sequences, and demonstrated performance advantages over best existing algorithms. The method for reference-free compression led to bit rates of 1.720 and 1.838 bits per base for bacteria and yeast, which were approximately 3.7% and 2.6% better than the state-of-the-art algorithms. Regarding performance with reference, we tested on the first Korean personal genome sequence data set, and our proposed method demonstrated a 189-fold compression rate, reducing the raw file size from 2986.8 MB to 15.8 MB at a comparable decompression cost with existing algorithms.

The characteristics of the periodic variation in acute myocardial infarction (AMI) and the subsequent effect on management and prognosis have not been fully investigated in a large number of Asian populations. From a prospective, observational multicenter online registry, 4,573 patients diagnosed as AMI in Korea from January to December 2006 were included. The highest incidence of AMI was between 8 a.m. and noon. The number of cases was highest in the winter and lowest in the autumn (13.6 vs 11.4 patients per day, P<0.001). Patients with symptom onset during working hours had a shorter time to first medical contact (203+/-288 min) compared with out-of-hours onset (230+/-288 min, P=0.003). In patients who underwent primary angioplasty, out-of hours symptom onset was associated with a greater time delay in both the patient's and the medical facility's response (door-to-balloon time out-of hours vs working hours: 101+/-54 min vs 84+/-44 min, P<0.001). In patients with ST-segment elevation myocardial infarction, symptoms to first medical contact showed a significant relationship to in-hospital mortality (for every 10 min of symptoms to first medical contact, odds ratio 1.006, 95% confidence interval 1.001-1.012, P=0.018) Circadian and periodic variation in AMI exists in Korean patients, which resulted in different patient behavior, hospital management and outcomes.

[The Korean Pharmaceutical Industry and the Expansion of the General Pharmaceuticals Market in the 1950-1960s].

After the Liberation, the Korean economy was dependent on relief supplies and aid after the ruin of the colonial regime and war. The pharmaceutical business also searched for their share in the delivery of military supplies and the distribution of relief supplies. The supply-side pharmaceutical policy made the pharmaceutical market a wholesale business. The gravity of the situation led to an increased importation of medical supplies, and wholesalers took the lead in establishing the distribution structure, whereas consumers and pharmaceutical business were relatively intimidated. The aid provided by the International Cooperation Administration (ICA) marked a turning point in the Korean pharmaceutical industry after the middle of the 1950s. ICA supplied raw materials and equipment funds, while the pharmaceutical business imported advanced technology and capital. The government invited the local production of medical substances, whereas pharmaceutical businesses replaced imported medical substances with locally produced antibiotics. After the 1960s, the production of antibiotics reached saturation. Pharmaceutical businesses needed new markets to break through the stalemate, so they turned their attention to vitamins and health tonics as general pharmaceuticals, as these were suitable for mass production and mass consumption. The modernized patent medicine market after the Opening of Korea was transformed into the contemporized general pharmaceuticals market equipped with the up-to-date facilities and technology in 1960s. Pharmaceutical businesses had to advertise these new products extensively and reform the distribution structure to achieve high profits. With the introduction of TV broadcasting, these businesses invested in TV advertising and generated sizable sales figures. They also established retail pharmacy and chain stores to reform the distribution structure. The end result was a dramatic expansion of the general pharmaceuticals market. The market for vitamins and health tonics showed particularly explosive growth. As Korean industrial workers worked night and day to increase exports in the 1960s, they needed vitamins and health tonics for recovery from fatigue and to support vitality. The expansion of the general pharmaceuticals market was accompanied by increases in numbers of pharmaceutical companies. Competition intensified between pharmaceutical companies, leading some companies to search for new survival plans. The pharmaceutical industry underwent structural reform in 1960s, replacing imported medical substances with local products and inventing the new market of general pharmaceuticals. The market for vitamins and health tonics was increased, and a successful product could support a pharmaceutical company. On the contrary, a general pharmaceutical could affect the very existence of the company: if a company chased a popular product and the imitation bubble burst, then the company have lost its competitiveness in the world market.

Metastatic spine tumor has become clinically important because of the availability of improved diagnostic tools and increases in survival periods in cancer patients. In spite of this interest, the burden of metastatic spine tumor on the general population has not been extensively reported. The aim of this 2009-2011 nationwide study of adult Koreans was to describe characteristics, medical use, and survival rate of patients with newly diagnosed metastatic spine tumors according to the primary tumor. This is a retrospective cohort study. A national health insurance database was used to identify a cohort of patients with newly diagnosed metastatic spine tumors. This study aimed to analyze characteristics, medical use, and survival rate of patients with newly diagnosed metastatic spine tumors according to the primary tumor. Data for patients with metastatic spine tumors were extracted from the Korean Health Insurance Review and Assessment Service database. Data included patient age, sex, health insurance type, comorbidities, medical cost, and hospital stay duration. Hospital stay duration and medical costs per person during 1 calendar year were evaluated. In addition, survival rates of patients with metastatic spine tumor according to primary tumor sites were evaluated. The incidence rate of spine metastasis increased with age, year of diagnosis, and the number of comorbidities (p≤.0001). The 6 most prevalent primary tumor sites were lung, liver and biliary tract, breast, colon, stomach, and prostate. Of patients with the 6 most prevalent primary tumors, total average annual medical costs, including inpatient and outpatient services, ranged from 12,734USD (prostate origin) to 15,556 USD (lung origin). Of patients with the 6 most prevalent primary tumors, total average annual hospital stay duration, including inpatient and outpatient services, ranged from 70.8 days (stomach origin) to 78.7 days (colon origin). Median overall survival duration in patients with metastatic spine tumor was 191 days. In addition to age, sex, and comorbidities, primary tumor sites (lung, liver and biliary tract, breast, stomach, and prostate) significantly affected survival rate. This nationwide study was able to depict the burden of metastatic spine tumor in Korea. The metastatic spine tumor incidence rate is highest in the group of 70- to 79-year-old men. Average annual medical costs ranged from 12,734 USD to 15,556 USD. The mean annual hospital stay duration was from 70.8 days to 78.7 days. In addition to age, sex, and comorbidities, primary tumor sites significantly affected the survival rate in patients with metastatic spine tumor. Copyright © 2016 Elsevier Inc. All rights reserved.

Using medication list--problem list mismatches as markers of potential error.

Carpenter, James D.; Gorman, Paul N.

The goal of this project was to specify and develop an algorithm that will check for drug and problem list mismatches in an electronic medical record (EMR). The algorithm is based on the premise that a patient's problem list and medication list should agree, and a mismatch may indicate medication error. Successful development of this algorithm could mean detection of some errors, such as medication orders entered into a wrong patient record, or drug therapy omissions, that are not otherwise detected via automated means. Additionally, mismatches may identify opportunities to improve problem list integrity. To assess the concept's feasibility, this study compared medications listed in a pharmacy information system with findings in an online nursing adult admission assessment, serving as a proxy for the problem list. Where drug and problem list mismatches were discovered, examination of the patient record confirmed the mismatch, and identified any potential causes. Evaluation of the algorithm in diabetes treatment indicates that it successfully detects both potential medication error and opportunities to improve problem list completeness. This algorithm, once fully developed and deployed, could prove a valuable way to improve the patient problem list, and could decrease the risk of medication error. PMID:12463796

Assistance algorithms for medical tasks have great potential to support physicians with their daily work. However, medicine is also one of the most demanding domains for computer-based support systems, since medical assistance tasks are complex and the practical experience of the physician is crucial. Recent developments in the area of cognitive computing appear to be well suited to tackle medicine as an application domain. We propose a system based on the idea of cognitive computing and consisting of auto-configurable medical assistance algorithms and their self-adapting combination. The system enables automatic execution of new algorithms, given they are made available as Medical Cognitive Apps and are registered in a central semantic repository. Learning components can be added to the system to optimize the results in the cases when numerous Medical Cognitive Apps are available for the same task. Our prototypical implementation is applied to the areas of surgical phase recognition based on sensor data and image progressing for tumor progression mappings. Our results suggest that such assistance algorithms can be automatically configured in execution pipelines, candidate results can be automatically scored and combined, and the system can learn from experience. Furthermore, our evaluation shows that the Medical Cognitive Apps are providing the correct results as they did for local execution and run in a reasonable amount of time. The proposed solution is applicable to a variety of medical use cases and effectively supports the automated and self-adaptive configuration of cognitive pipelines based on medical interpretation algorithms.

The monitoring of the radioactive xenon isotopes 131mXe, 133Xe, 133mXe, and 135Xe is important for the detection of nuclear explosions. While backgrounds of the xenon isotopes are short-lived, they are constantly replenished from activities dominated by the fission-based production of 99Mo used for medical procedures. One of the most critical locations on earth for the monitoring of nuclear explosions is the Korean peninsula, where the Democratic Republic of North Korea (DPRK) has announced that it had conducted three nuclear tests between 2009 and 2013.

Resource allocation is a critical aspect of space mission planning. All resources, including medical resources, are subject to a number of mission constraints such a maximum mass and volume. However, unlike many resources, there is often limited understanding in how to optimize medical resources for a mission. The Integrated Medical Model (IMM) is a probabilistic model that estimates medical event occurrences and mission outcomes for different mission profiles. IMM simulates outcomes and describes the impact of medical events in terms of lost crew time, medical resource usage, and the potential for medically required evacuation. Previously published work describes an approach that uses the IMM to generate optimized medical kits that maximize benefit to the crew subject to mass and volume constraints. We improve upon the results obtained previously and extend our approach to minimize mass and volume while meeting some benefit threshold. METHODS We frame the medical kit optimization problem as a modified knapsack problem and implement an algorithm utilizing dynamic programming. Using this algorithm, optimized medical kits were generated for 3 mission scenarios with the goal of minimizing the medical kit mass and volume for a specified likelihood of evacuation or Crew Health Index (CHI) threshold. The algorithm was expanded to generate medical kits that maximize likelihood of evacuation or CHI subject to mass and volume constraints. RESULTS AND CONCLUSIONS In maximizing benefit to crew health subject to certain constraints, our algorithm generates medical kits that more closely resemble the unlimited-resource scenario than previous approaches which leverage medical risk information generated by the IMM. Our work here demonstrates that this algorithm provides an efficient and effective means to objectively allocate medical resources for spaceflight missions and provides an effective means of addressing tradeoffs in medical resource allocations and crew mission success parameters.

This paper is aimed to study the clustering method for Chinese medicine (CM) medical cases. The traditional K-means clustering algorithm had shortcomings such as dependence of results on the selection of initial value, trapping in local optimum when processing prescriptions form CM medical cases. Therefore, a new clustering method based on the collaboration of firefly algorithm and simulated annealing algorithm was proposed. This algorithm dynamically determined the iteration of firefly algorithm and simulates sampling of annealing algorithm by fitness changes, and increased the diversity of swarm through expansion of the scope of the sudden jump, thereby effectively avoiding premature problem. The results from confirmatory experiments for CM medical cases suggested that, comparing with traditional K-means clustering algorithms, this method was greatly improved in the individual diversity and the obtained clustering results, the computing results from this method had a certain reference value for cluster analysis on CM prescriptions.

In an obstetrical setting, inaccurate medication histories at hospital admission may result in failure to identify potentially harmful treatments for patients and/or their fetus(es). This prospective study was conducted to assess average concordance rates between (1) a medication list obtained with a one-page structured medication history algorithm developed for the obstetrical setting and (2) the medication list reported in medical records and obtained by open-ended questions based on standard procedures. Both lists were converted into concordance rate using a best possible medication history approach as the reference (information obtained by patients, prescribers and community pharmacists' interviews). The algorithm-based method obtained a higher average concordance rate than the standard method, with respectively 90.2% [CI95% 85.8-94.3] versus 24.6% [CI95%15.3-34.4] concordance rates (p<0.01). Our algorithm-based method strongly enhanced the accuracy of the medication history in our obstetric population, without using substantial resources. Its implementation is an effective first step to the medication reconciliation process, which has been recognized as a very important component of patients' drug safety.

The Temperament and Character of Korean Male Conscripts with Military Maladjustment-A Preliminary Study

Lee, Sung-Bu

2013-01-01

Objective Recently, an increasing number of Korean male conscripts have been retiring because of military maladjustment despite the presence of qualifying medical and psychological screening tests in the Korean army. These problems suggest the presence of a common personality problem. To further examine this possibility, the present study used Cloninger's psychobiological model to investigate the temperament and character of soldiers suffering from military maladjustment. Methods Seventy-nine maladjusted male conscripts and eighty-seven controls enrolled at the 1596th unit from April 2011 to June 2012 participated in the present study. To measure participant personality, we used the Korean version of the Temperament and Character Inventory, Revised-Short. We used logistic regression analysis to examine the association between TCI-RS scores and risk of military maladjustment. Results The maladjustment group had a lower rank, socioeconomic status, education level, and a shorter duration of military service than the control group. The harm avoidance and self-transcendence scores were significantly higher in the maladjustment group, with lower scores for reward dependence, persistence, self-directedness, and cooperativeness scores. However, of these measures, only low cooperativeness was associated with an increased risk of military maladjustment. Conclusion These results suggest that a low level of cooperativeness can predict military inadequacy. Maladjusted male conscripts may have different personality characteristics from normals. To validate our results, further follow-up or cohort studies with a larger sample will be required. PMID:23798960

Allergic rhinitis (AR) is one of the most common chronic allergic respiratory diseases worldwide. Various practical guidelines for AR have been developed and updated to improve the care of AR patients; however, up to 40% patients remain symptomatic. The unmet need for AR care is one of the greatest public health problems in the world. The gaps between guideline and real-world practice, and differences according to the region, culture, and medical environments may be the causes of unmet needs for AR care. Because there is no evidence-based AR practical guideline reflecting the Korean particularity, various needs are increasing. The purpose of the study was to evaluate whether existing guidelines are sufficient for AR patient management in real practice and whether development of regional guidelines to reflect regional differences is needed in Korea. A total of 99 primary physicians comprising internists, pediatricians, and otolaryngologists (n=33 for each) were surveyed by a questionnaire relating to unmet needs for AR care between June 2 and June 16 of 2014. Among 39 question items, participants strongly agreed on 15 items that existing guidelines were highly insufficient and needed new guidelines. However, there was some disagreement according to specialties for another 24 items. In conclusion, the survey results demonstrated that many physicians did not agree with the current AR guideline, and a new guideline reflecting Korean particularity was needed.

Avison, provided him with an understanding of western civilization. After entering Chejungwon Medical School in 1900, Dr. Park learned basic sciences, basic medical sciences like anatomy and physiology, and other Western medical specialties such as internal medicine and surgery. He graduated from medical school in 1908 and received Government Certificate from Home Office, the first in Korea in this field, which granted the right to practice medicine. His certificate number was 4th overall. As both a doctor and a talented musician, Dr. Park actively participated in the social enlightenment movement. He was quite progressive in his time, having surpassed the social limitations as a son of a butcher, as well as actively propagating his knowledge of Western civilization onto others. After graduation, he had served as a professor at the school he graduated from, until he went into exile in Manchuria in 1917 due to the annexation of Korea by Japan in 1910. There, he opened a hospital and provided medical treatment for Koreans. He also established a school for young Koreans, inspiring them with a sense of nationalism. Also, Dr. Park was an active member of various Independence Movement Organizations in Manchuria. Then in 1932, at the time when Japan took control of Manchuria, his school was closed down. As a result, Dr. Park couldn't help but stop his anti-Japanese activities. In 1936, he returned to his homeland and passed away in 1940, just five years before the liberation of Korea from Japanese occupation.

Current global and Korean issues in radiation safety of nuclear medicine procedures.

Song, H C

In recent years, the management of patient doses in medical imaging has evolved as concern about radiation exposure has increased. Efforts and techniques to reduce radiation doses are focussed not only on the basis of patient safety, but also on the fundamentals of justification and optimisation in cooperation with international organisations such as the International Commission on Radiological Protection, the International Atomic Energy Agency, and the World Health Organization. The Image Gently campaign in children and Image Wisely campaign in adults to lower radiation doses have been initiated in the USA. The European Association of Nuclear Medicine paediatric dosage card, North American consensus guidelines, and Nuclear Medicine Global Initiative have recommended the activities of radiopharmaceuticals that should be administered in children. Diagnostic reference levels (DRLs), developed predominantly in Europe, may be an important tool to manage patient doses. In Korea, overexposure to radiation, even from the use of medical imaging, has become a public issue, particularly since the accident at the Fukushima nuclear power plant. As a result, the Korean Nuclear Safety and Security Commission revised the technical standards for radiation safety management in medical fields. In parallel, DRLs for nuclear medicine procedures have been collected on a nationwide scale. Notice of total effective dose from positron emission tomography-computed tomography for cancer screening has been mandatory since mid-November 2014. © The International Society for Prosthetics and Orthotics.

Musculoskeletal diseases are becoming increasingly important due to population aging. However, studies on the economic burden of musculoskeletal disease in Korea are scarce. Therefore, we conducted a population-based study to measure the economic burden of musculoskeletal disease in Korea using nationally representative data. This study used a variety of data sources such as national health insurance statistics, the Korea Health Panel study and cause of death reports generated by the Korea National Statistical Office to estimate the economic burden of musculoskeletal disease. The total cost of musculoskeletal disease was estimated as the sum of direct medical care costs, direct non-medical care costs, and indirect costs. Direct medical care costs are composed of the costs paid by the insurer and patients, over the counter drugs costs, and other costs such as medical equipment costs. Direct non-medical costs are composed of transportation and caregiver costs. Indirect costs are the sum of the costs associated with premature death and the costs due to productivity loss. Age, sex, and disease specific costs were estimated. Among the musculoskeletal diseases, the highest costs are associated with other dorsopathies, followed by disc disorder and arthrosis. The direct medical and direct non-medical costs of all musculoskeletal diseases were $4.18 billion and $338 million in 2008, respectively. Among the indirect costs, those due to productivity loss were $2.28 billion and costs due to premature death were $79 million. The proportions of the total costs incurred by male and female patients were 33.8% and 66.2%, respectively, and the cost due to the female adult aged 20-64 years old was highest. The total economic cost of musculoskeletal disease was $6.89 billion, which represents 0.7% of the Korean gross domestic product. The economic burden of musculoskeletal disease in Korea is substantial. As the Korean population continues to age, the economic burden of musculoskeletal disease will continue to increase. Policy measures aimed at controlling the cost of musculoskeletal disease are therefore required.

[The medical theory of Lee Je-ma and its character].

Lee, Kyung-Lock

2005-12-01

Lee Je-ma 1837-1900) was a prominent scholar as well as an Korean physician. classified every people into four distinctive types: greater yang [tai yang] person, lesser yin [shao yin] person, greater yin [tai yin] person, lesser yin [shao yin] person. This theory would dictate proper treatment for each type in accordance with individual differences of physical and temperament features. Using these four types he created The Medical Science of Four Types. This article is intended to look into the connection between Lee Je-Ma's 'The Medical Science of Four Types' and 'The Modern' with organizing his ideas about the human body and the human being. Through The Modern, the theory of human being underwent a complete change. Human being in The Premodern, which was determined by sex, age and social status has been changed to the individual human being, which is featured by equality. Lee Je-Ma's medical theory of The Medical Science of Four Types would be analyzed as follow. His concept of human body is oriented toward observable objectivity. But on the other hand, it still remains transcendent status of medical science, which is subordinated by philosophy. According to Lee Je-Ma's theory of human being, human is an equal individual in a modern way of thinking, not as a part of hierarchical group. But on the other hand, it still remains incomplete from getting rid of morality aspect that includes virtue and vice in the concept of human body. The common factors in Lee Je-Ma's ideas about the human body and the human being is 'Dualism of mind and body that means all kinds of status and results depends on each individual. As is stated above, Lee Je-Ma's medical theory has many aspects of The Modern and it proves that Korean traditional medicine could be modernized by itself.

Automation of a high risk medication regime algorithm in a home health care population.

Create an automated algorithm for predicting elderly patients' medication-related risks for readmission and validate it by comparing results with a manual analysis of the same patient population. Outcome and Assessment Information Set (OASIS) and medication data were reused from a previous, manual study of 911 patients from 15 Medicare-certified home health care agencies. The medication data was converted into standardized drug codes using APIs managed by the National Library of Medicine (NLM), and then integrated in an automated algorithm that calculates patients' high risk medication regime scores (HRMRs). A comparison of the results between algorithm and manual process was conducted to determine how frequently the HRMR scores were derived which are predictive of readmission. HRMR scores are composed of polypharmacy (number of drugs), Potentially Inappropriate Medications (PIM) (drugs risky to the elderly), and Medication Regimen Complexity Index (MRCI) (complex dose forms, instructions or administration). The algorithm produced polypharmacy, PIM, and MRCI scores that matched with 99%, 87% and 99% of the scores, respectively, from the manual analysis. Imperfect match rates resulted from discrepancies in how drugs were classified and coded by the manual analysis vs. the automated algorithm. HRMR rules lack clarity, resulting in clinical judgments for manual coding that were difficult to replicate in the automated analysis. The high comparison rates for the three measures suggest that an automated clinical tool could use patients' medication records to predict their risks of avoidable readmissions.

2010-01-01

To determine the relations between post-stroke aphasia severity and aphasia type and lesion location, a retrospective review was undertaken using the medical records of 97 Korean patients, treated within 90 days of onset, for aphasia caused by unilateral left hemispheric stroke. Types of aphasia were classified according to the validated Korean version of the Western Aphasia Battery (K-WAB), and severities of aphasia were quantified using WAB Aphasia Quotients (AQ). Lesion locations were classified as cortical or subcortical, and were determined by magnetic resonance imaging. Two-step cluster analysis was performed using AQ values to classify aphasia severity by aphasia type and lesion location. Cluster analysis resulted in four severity clusters: 1) mild; anomic type, 2) moderate; Wernicke's, transcortical motor, transcortical sensory, conduction, and mixed transcortical types, 3) moderately severe; Broca's aphasia, and 4) severe; global aphasia, and also in three lesion location clusters: 1) mild; subcortical 2) moderate; cortical lesions involving Broca's and/or Wernicke's areas, and 3) severe; insular and cortical lesions not in Broca's or Wernicke's areas. These results revealed that within 3 months of stroke, global aphasia was the more severely affected type and cortical lesions were more likely to affect language function than subcortical lesions.

Attitudes toward hepatitis B virus among Vietnamese, Chinese and Korean Americans in the Houston area, Texas.

We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. We use qualitative methods in 12 focus groups (n = 113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine--when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings.

The Illness Intrusiveness Rating Scale (IIRS) measures illness-induced disruptions to 13 domains of lifestyles, activities, and interests. A stable three-factor structure has been well documented; however, the cross-cultural validity of this scale needs to be tested. This study investigated the factor structure of the Korean version of IIRS in 712 outpatients at a university medical center. A predominant diagnosis of the patients was rheumatoid arthritis (47%). The Center for Epidemiological Studies-Depression Scale (CES-D), and Health Assessment Questionnaire (HAQ) were also administered. Exploratory Principal Component Analysis identified a two-factor structure, "Relationships and Personal Development (RPD)" and "Instrumental", accounting for 57% of the variance. Confirmatory analyses extracted an identical factor structure. However, a goodness-of-the fit test failed to support two-factor solution (chi(2)=138.2, df=43, p<.001). Two factors had high internal consistency (RPD, alpha=.89; Instrumental, alpha=.75) and significantly correlated with scores of HAQ (RPD, r=.53, p<.001; Instrumental, .r=44, p<.001) and CES-D (RPD, .r=55, p<.001; Instrumental, .r=43, p<.001). These findings supported construct validity of the Korean version of IIRS, but did not support cross-cultural equivalence of the factor structure.

What Factors Impact Consumer Perception of the Effectiveness of Health Information Sites? An Investigation of the Korean National Health Information Portal

PubMed Central

2017-01-01

Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy.

The print media is still one of major sources for health-related information. To shed light on how the media accurately delivers information for post-traumatic stress disorder (PTSD), we searched the newspaper articles and analyzed their contents for accuracy in the description of symptoms, causes, and treatment of PTSD. The articles featuring PSTD were searched from the very first available to 2010 at on-line search systems of three major Korean newspapers. A total of 123 articles appeared and the first article appeared in 1984. The number of articles steadily increased till the early 2000s but we found the robust increase in the late 2000s. Among the mentioned symptoms of PTSD: re-experience (39%) was most common, followed by avoidance or numbing (28%) and hyperarousal (22%). Of the 29 articles mentioning treatment of PTSD, 13 mentioned psychotherapy only and 11 mentioned both psychotherapy and medication equally. However, the psychotherapies mentioned were non-specific and only five articles mentioned any empirically supported therapies. The number of articles on PTSD in Korean newspapers has continually increased during the last three decades. However, the quality of information on the treatment of PTSD was questionable.

A great wealth of information is hidden amid medical research data that in some cases cannot be easily analyzed, if at all, using classical statistical methods. Inspired by nature, metaheuristic algorithms have been developed to offer optimal or near-optimal solutions to complex data analysis and decision-making tasks in a reasonable time. Due to their powerful features, metaheuristic algorithms have frequently been used in other fields of sciences. In medicine, however, the use of these algorithms are not known by physicians who may well benefit by applying them to solve complex medical problems. Therefore, in this paper, we introduce the genetic algorithm and its applications in medicine. The use of the genetic algorithm has promising implications in various medical specialties including radiology, radiotherapy, oncology, pediatrics, cardiology, endocrinology, surgery, obstetrics and gynecology, pulmonology, infectious diseases, orthopedics, rehabilitation medicine, neurology, pharmacotherapy, and health care management. This review introduces the applications of the genetic algorithm in disease screening, diagnosis, treatment planning, pharmacovigilance, prognosis, and health care management, and enables physicians to envision possible applications of this metaheuristic method in their medical career.].

Algorithmic and user study of an autocompletion algorithm on a large medical vocabulary.

2012-02-01

Autocompletion supports human-computer interaction in software applications that let users enter textual data. We will be inspired by the use case in which medical professionals enter ontology concepts, catering the ongoing demand for structured and standardized data in medicine. Goal is to give an algorithmic analysis of one particular autocompletion algorithm, called multi-prefix matching algorithm, which suggests terms whose words' prefixes contain all words in the string typed by the user, e.g., in this sense, opt ner me matches optic nerve meningioma. Second we aim to investigate how well it supports users entering concepts from a large and comprehensive medical vocabulary (snomed ct). We give a concise description of the multi-prefix algorithm, and sketch how it can be optimized to meet required response time. Performance will be compared to a baseline algorithm, which gives suggestions that extend the string typed by the user to the right, e.g. optic nerve m gives optic nerve meningioma, but opt ner me does not. We conduct a user experiment in which 12 participants are invited to complete 40 snomed ct terms with the baseline algorithm and another set of 40 snomed ct terms with the multi-prefix algorithm. Our results show that users need significantly fewer keystrokes when supported by the multi-prefix algorithm than when supported by the baseline algorithm. The proposed algorithm is a competitive candidate for searching and retrieving terms from a large medical ontology. Copyright © 2011 Elsevier Inc. All rights reserved.

[An improved medical image fusion algorithm and quality evaluation].

Medical image fusion is of very important value for application in medical image analysis and diagnosis. In this paper, the conventional method of wavelet fusion is improved,so a new algorithm of medical image fusion is presented and the high frequency and low frequency coefficients are studied respectively. When high frequency coefficients are chosen, the regional edge intensities of each sub-image are calculated to realize adaptive fusion. The choice of low frequency coefficient is based on the edges of images, so that the fused image preserves all useful information and appears more distinctly. We apply the conventional and the improved fusion algorithms based on wavelet transform to fuse two images of human body and also evaluate the fusion results through a quality evaluation method. Experimental results show that this algorithm can effectively retain the details of information on original images and enhance their edge and texture features. This new algorithm is better than the conventional fusion algorithm based on wavelet transform.

Catastrophic Health Expenditures for Households with Disabled Members: Evidence from the Korean Health Panel

PubMed Central

2016-01-01

Persons with disabilities use more health care services due to ill health and face higher health care expenses and burden. This study explored the incidence of catastrophic health expenditures of households with persons with disabilities compared to that of those without such persons. We used the Korean Health Panel (KHP) dataset for the years 2010 and 2011. The final sample was 5,610 households; 800 (14.3%) of these were households with a person with a disability and 4,810 (85.7%) were households without such a person. Households with a person with a disability faced higher catastrophic health expenditures, spending about 1.2 to 1.4 times more of their annual living expenditures for out-of-pocket medical expenses, compared to households without persons with disabilities. Households having low economic status and members with chronic disease were more likely to face catastrophic health expenditures, while those receiving public assistance were less likely. Exemption or reduction of out-of-pocket payments in the National Health Insurance and additional financial support are needed so that the people with disabilities can use medical services without suffering financial crisis.

2010-09-01

Suicide is a major concern for increasing mortality in bipolar patients, but risk factors for suicide in bipolar disorder remain complex, including Korean patients. Medical records of bipolar patients were retrospectively reviewed to detect significant clinical characteristics associated with suicide attempts. A total of 579 medical records were retrospectively reviewed. Bipolar patients were divided into two groups with the presence of a history of suicide attempts. We compared demographic characteristics and clinical features between the two groups using an analysis of covariance and chi-square tests. Finally, logistic regression was performed to evaluate significant risk factors associated with suicide attempts in bipolar disorder. The prevalence of suicide attempt was 13.1% in our patient group. The presence of a depressive first episode was significantly different between attempters and nonattempters. Logistic regression analysis revealed that depressive first episodes and bipolar II disorder were significantly associated with suicide attempts in those patients. Clinicians should consider the polarity of the first mood episode when evaluating suicide risk in bipolar patients. This study has some limitations as a retrospective study and further studies with a prospective design are needed to replicate and evaluate risk factors for suicide in patients with bipolar disorder.

2016-01-01

The Korean National Health Insurance, which provides universal coverage for the entire Korean population, is now facing financial instability. Frequent emergency department (ED) users may represent a medically vulnerable population who could benefit from interventions that both improve care and lower costs. To understand the nature of frequent ED users in Korea, we analyzed claims data from a population-based national representative sample. We performed both bivariate and multivariable analyses to investigate the association between patient characteristics and frequent ED use (4+ ED visits in a year) using claims data of a 1% random sample of the Korean population, collected in 2009. Among 156,246 total ED users, 4,835 (3.1%) were frequent ED users. These patients accounted for 14% of 209,326 total ED visits and 17.2% of $76,253,784 total medical expenses generated from all ED visits in the 1% data sample. Frequent ED users tended to be older, male, and of lower socio-economic status compared with occasional ED users (p < 0.001 for each). Moreover, frequent ED users had longer stays in the hospital when admitted, higher probability of undergoing an operative procedure, and increased mortality. Among 8,425 primary diagnoses, alcohol-related complaints and schizophrenia showed the strongest positive correlation with the number of ED visits. Among the frequent ED users, mortality and annual outpatient department visits were significantly lower in the alcohol-related patient subgroup compared with other frequent ED users; furthermore, the rate was even lower than that for non-frequent ED users. Our findings suggest that expanding mental health and alcohol treatment programs may be a reasonable strategy to decrease the dependence of these patients on the ED. PMID:26809051

On 16 June 2016, the Korean Cancer Association (KCA) and Union for International Cancer Control-Asia Regional Office (UICC-ARO) organized a joint symposium as part of the official program of the 42nd Annual Meeting of the Korean Cancer Association to discuss the topic 'Cross-boundary Cancer Studies: Cancer and Universal Health Coverage (UHC) in Asia.' Universal Health Coverage is included in the Sustainable Development Goals adopted by the United Nations as part of the 2030 Agenda for Sustainable Development. The objectives of UHC are to ensure that all people can receive high-quality medical services, are protected from public health risks, and are prevented from falling into poverty due to medical costs or loss of income arising from illness. The participants discussed the growing cost of cancer in the Asian region and the challenges that this poses to the establishment and deployment of UHC in the countries of Asia, all of which face budgetary and other systemic constraints in controlling cancer in the region. Representatives from Korea, Japan and Indonesia reported on the status of UHC in their countries and the challenges that are being faced, many of which are common to other countries in Asia. In addition to country-specific presentations about the progress of and challenges facing UHC, there were also presentations from WHO Kobe Centre concerning advancing UHC in non-communicable diseases and prospects for further collaboration and research on UHC. A presentation from the University of Tokyo also highlighted the need to focus on multidisciplinary studies in an age of globalization and digitization. © The Author 2017.

2017-11-01

Pain is often associated with a more rapid progression of cognitive and functional decline, and behavioral disturbance in dementia. Therefore, it is essential to accurately assesses pain for proper intervention in patients with dementia. The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is an excellent behaviour scale which includes most of the domains that are recommended by the American Geriatrics Society to evaluate when assessing pain in patients with dementia. The purpose of this study was to develop the Korean version of the FLACC (K-FLACC) and to verify its reliability and validity in assessing pain of elderly patients with dementia. We developed the K-FLACC to consist of the five domains (face, legs, activity, cry, and consolability) with scores of 0, 1, and 2 for each domain and a total score ranging from 0 to 10 as in the original FLACC. Eighty-eight patients with dementia who visited Konkuk University Medical Center were evaluated. The K-FLACC revealed good validity as compared to the Numeric Rating Scale (NRS; r = 0.617, P < 0.001) and the Face Pain Scale (FPS; r = 0.350, P = 0.001). All of the five domains of the K-FLACC were related to the NRS and FPS, in which the activity domain showed the highest correlation. Test-retest reliability was excellent, as the intra-class correlation coefficient comparing the retest to test was 0.73 (95% confidence interval, 0.59-0.82). Our results show that the K-FLACC is a suitable and valuable scale to assess pain in patients with dementia in Korea. © 2017 The Korean Academy of Medical Sciences.

To identify barriers to exercise in Korean colorectal cancer patients and survivors, and to analyze differences in exercise barriers by age, gender, treatment status, and physical activity level. A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation. The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (p<0.001). Those who were receiving treatment rated poor health (p=0.0005) and cancer-related factors as greater exercise barriers compared to those who were not receiving treatment. A multivariate model found that other demographic and medical status were not potential factors that may affect exercise participation. Further, for those who were not participating in physical activity, tendency to be physically inactive (p<0.001) and lack of exercise skill (p<0.001) were highly significant barriers, compared to those who were participating in physical activity. Also, for those who were not meeting ACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were. Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.

Background Hypertension and musculoskeletal disorders are highly prevalent in adult populations. The objective of this study was to investigate the association between hypertension and prevalence of low back pain (LBP) and osteoarthritis in Koreans. Methods A total 17,128 participants (age ≥20 years) who answered low back pain and osteoarthritis items in the 4th Korean National Health and Nutrition Examination Survey (2007–2009) were analyzed. Odds ratios were calculated using logistic regression and were adjusted for age, sex, income level, education, occupation, BMI, smoking status, alcohol consumption, and physical activity. Results Lifetime prevalence of LBP in hypertensive subjects was 34.4%, and that of osteoarthritis 26.2%. LBP prevalence was significantly lower in hypertensives (fully adjusted OR 0.79; 95% CI 0.70–0.90), and both LBP and osteoarthritis prevalence was significantly lower in participants with systolic blood pressure ≥140mmHg than those with <120mmHg (fully adjusted OR 0.81; 95% CI 0.70–0.94, and 0.81; 95% CI 0.68–0.96, respectively). Prevalence of LBP in subjects with diastolic blood pressure ≥90mmHg was also significantly lower than those with <80mmHg (fully adjusted OR 0.73; 95% CI 0.63–0.85). LBP and osteoarthritis prevalence did not differ by systolic or diastolic blood pressure interval in respondents taking antihypertensive medication. LBP and osteoarthritis prevalence increased with longer hypertension duration (fully adjusted p for trend 0.028, and 0.0008, respectively). Conclusions Hypertension showed an inverse relationship with LBP and osteoarthritis prevalence, which may be ascribed to hypertension-associated hypalgesia, and antihypertensive medication intake and longer hypertension duration attenuated this association.

To determine the outcomes of Korean patients with fibromyalgia (FM) and to identify prognostic factors associated with improvement at 1-year follow-up. Forty-eight patients with FM were enrolled and examined every 3 months for 1 year. At the time of enrollment, we interviewed all patients using a structured questionnaire that recorded socio-demographic data, current or past FM symptoms, and current use of relevant medications. Tender point counts and scores were assessed by thumb palpation. Patients were asked to complete the Korean versions of the Fibromyalgia Impact Questionnaire (FIQ), the Brief Fatigue Inventory, the SF-36, the Beck Depression Inventory, the State-Trait Anxiety Inventory (STAI), the Self-Efficacy Scale, and the Social Support Scale. Tender points, FIQ scores, and the use of relevant medications were recorded during one year of follow-up. Of the 48 patients, 32 (66.7%) had improved FIQ scores 1 year after enrollment. Improved patients had higher baseline FIQ scores (68.4±13.9 vs. 48.4±20.8, p=0.001) and STAI-II scores (55.8±10.9 vs. 11.5±11.5, p=0.022). Patients treated with pregabalin were more likely to improve after 1 year, based on the FIQ scores (71.9% vs. 37.5%, p=0.031). On multivariate logistic regression analysis, a higher STAI-II score at the time of enrollment and pregabalin treatment during one year of follow-up were the predictors of improvement. Two-thirds of our Korean FM patients experienced some clinical improvement by 1-year follow-up. A high baseline STAI-II score and treatment with pregabalin were the important predictor of improved FM.

In order to solve the problem of medical image segmentation, a wavelet neural network medical image segmentation algorithm based on combined maximum entropy criterion is proposed. Firstly, we use bee colony algorithm to optimize the network parameters of wavelet neural network, get the parameters of network structure, initial weights and threshold values, and so on, we can quickly converge to higher precision when training, and avoid to falling into relative extremum; then the optimal number of iterations is obtained by calculating the maximum entropy of the segmented image, so as to achieve the automatic and accurate segmentation effect. Medical image segmentation experiments show that the proposed algorithm can reduce sample training time effectively and improve convergence precision, and segmentation effect is more accurate and effective than traditional BP neural network (back propagation neural network : a multilayer feed forward neural network which trained according to the error backward propagation algorithm.

In this paper we propose a stitching algorithm of medical images into one. The algorithm is designed to stitching the medical x-ray imaging, biological particles in microscopic images, medical microscopic images and other. Such image can improve the diagnosis accuracy and quality for minimally invasive studies (e.g., laparoscopy, ophthalmology and other). The proposed algorithm is based on the following steps: the searching and selection areas with overlap boundaries; the keypoint and feature detection; the preliminary stitching images and transformation to reduce the visible distortion; the search a single unified borders in overlap area; brightness, contrast and white balance converting; the superimposition into a one image. Experimental results demonstrate the effectiveness of the proposed method in the task of image stitching.

Non-rigid medical image registration is a popular subject in the research areas of the medical image and has an important clinical value. In this paper we put forward an improved algorithm of Demons, together with the conservation of gray model and local structure tensor conservation model, to construct a new energy function processing multi-modal registration problem. We then applied the L-BFGS algorithm to optimize the energy function and solve complex three-dimensional data optimization problem. And finally we used the multi-scale hierarchical refinement ideas to solve large deformation registration. The experimental results showed that the proposed algorithm for large de formation and multi-modal three-dimensional medical image registration had good effects.

Motivation: Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. Results: We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp.

To step up from current day fusion experiments to power producing fusion reactors, it is necessary to control long pulse, burning plasmas. Stability and confinement properties of tokamak fusion reactors are determined by the current or q profile. In order to control the q profile, it is necessary to measure it in real-time. A real-time motional Stark effect diagnostic is being developed at Korean Superconducting Tokamak for Advanced Research for this purpose. This paper focuses on 3 topics important for real-time measurements: minimize the use of ad hoc parameters, minimize external influences and a robust and fast analysis algorithm. Specifically, we have looked into extracting the retardance of the photo-elastic modulators from the signal itself, minimizing the influence of overlapping beam spectra by optimizing the optical filter design and a multi-channel, multiharmonic phase locking algorithm.

The Integrated Medical Model (IMM) is a probabilistic model that estimates medical event occurrences and mission outcomes for different mission profiles. IMM simulation outcomes describing the impact of medical events on the mission may be used to optimize the allocation of resources in medical kits. Efficient allocation of medical resources, subject to certain mass and volume constraints, is crucial to ensuring the best outcomes of in-flight medical events. We implement a new approach to this medical kit optimization problem. METHODS We frame medical kit optimization as a modified knapsack problem and implement an algorithm utilizing a dynamic programming technique. Using this algorithm, optimized medical kits were generated for 3 different mission scenarios with the goal of minimizing the probability of evacuation and maximizing the Crew Health Index (CHI) for each mission subject to mass and volume constraints. Simulation outcomes using these kits were also compared to outcomes using kits optimized..RESULTS The optimized medical kits generated by the algorithm described here resulted in predicted mission outcomes more closely approached the unlimited-resource scenario for Crew Health Index (CHI) than the implementation in under all optimization priorities. Furthermore, the approach described here improves upon in reducing evacuation when the optimization priority is minimizing the probability of evacuation. CONCLUSIONS This algorithm provides an efficient, effective means to objectively allocate medical resources for spaceflight missions using the Integrated Medical Model.

Telemedicine is a booming healthcare practice that has facilitated the exchange of medical data and expertise between healthcare entities. However, the widespread use of telemedicine applications requires a secured scheme to guarantee confidentiality and verify authenticity and integrity of exchanged medical data. In this paper, we describe a region-based, crypto-watermarking algorithm capable of providing confidentiality, authenticity, and integrity for medical images of different modalities. The proposed algorithm provides authenticity by embedding robust watermarks in images' region of non-interest using SVD in the DWT domain. Integrity is provided in two levels: strict integrity implemented by a cryptographic hash watermark, and content-based integrity implemented by a symmetric encryption-based tamper localization scheme. Confidentiality is achieved as a byproduct of hiding patient's data in the image. Performance of the algorithm was evaluated with respect to imperceptibility, robustness, capacity, and tamper localization, using different medical images. The results showed the effectiveness of the algorithm in providing security for telemedicine applications.

Medical Image Encryption: An Application for Improved Padding Based GGH Encryption Algorithm

Medical images are regarded as important and sensitive data in the medical informatics systems. For transferring medical images over an insecure network, developing a secure encryption algorithm is necessary. Among the three main properties of security services (i.e., confidentiality, integrity, and availability), the confidentiality is the most essential feature for exchanging medical images among physicians. The Goldreich Goldwasser Halevi (GGH) algorithm can be a good choice for encrypting medical images as both the algorithm and sensitive data are represented by numeric matrices. Additionally, the GGH algorithm does not increase the size of the image and hence, its complexity will remain as simple as O(n2). However, one of the disadvantages of using the GGH algorithm is the Chosen Cipher Text attack. In our strategy, this shortcoming of GGH algorithm has been taken in to consideration and has been improved by applying the padding (i.e., snail tour XORing), before the GGH encryption process. For evaluating their performances, three measurement criteria are considered including (i) Number of Pixels Change Rate (NPCR), (ii) Unified Average Changing Intensity (UACI), and (iii) Avalanche effect. The results on three different sizes of images showed that padding GGH approach has improved UACI, NPCR, and Avalanche by almost 100%, 35%, and 45%, respectively, in comparison to the standard GGH algorithm. Also, the outcomes will make the padding GGH resist against the cipher text, the chosen cipher text, and the statistical attacks. Furthermore, increasing the avalanche effect of more than 50% is a promising achievement in comparison to the increased complexities of the proposed method in terms of encryption and decryption processes.

A number of clinical decision tools for osteoporosis risk assessment have been developed to select postmenopausal women for the measurement of bone mineral density. We developed and validated machine learning models with the aim of more accurately identifying the risk of osteoporosis in postmenopausal women, and compared with the ability of a conventional clinical decision tool, osteoporosis self-assessment tool (OST). We collected medical records from Korean postmenopausal women based on the Korea National Health and Nutrition Surveys (KNHANES V-1). The training data set was used to construct models based on popular machine learning algorithms such as support vector machines (SVM), random forests (RF), artificial neural networks (ANN), and logistic regression (LR) based on various predictors associated with low bone density. The learning models were compared with OST. SVM had significantly better area under the curve (AUC) of the receiver operating characteristic (ROC) than ANN, LR, and OST. Validation on the test set showed that SVM predicted osteoporosis risk with an AUC of 0.827, accuracy of 76.7%, sensitivity of 77.8%, and specificity of 76.0%. We were the first to perform comparisons of the performance of osteoporosis prediction between the machine learning and conventional methods using population-based epidemiological data. The machine learning methods may be effective tools for identifying postmenopausal women at high risk for osteoporosis.

To determine the association between arginine vasopressin receptor 1A gene (AVPR1A) and autism spectrum disorders (ASDs), we examined 3 single nucleotide polymorphisms (SNPs), namely, rs7294536, rs3759292, and rs10877969, in the promoter region of AVPR1A by using a family-based association test (FBAT) in 151 Korean trios. Our results demonstrated a statistically significant association between autism and SNPs (additive model: rs7294536, chi(2)=9.328, df=2, P=0.002; rs10877969, chi(2)=11.529, df=2, P<0.001) as well as between autism and haplotype analysis (additive model: chi(2)=14.122, df=3, P=0.003). In addition, we found that ADI-R scores calculated by using a diagnostic algorithm for failure to develop peer relationships (A2) were higher in subjects having the AA genotype than in subjects having the AG and GG genotypes of rs7294536. Thus, our study provides evidence for a possible association between these SNPs and the phenotype of ASDs. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

Health development experience in North and South Korea.

The purpose of this study is to compare the difference in health status between South Koreans and North Koreans and to identify factors responsible for the remarkable improvements in the health status of South Koreans. In order to examine the causes of the difference in health level, the health indices and their determinants of two Koreas were analyzed in time order. As of the year 2000, the average life expectancy at birth is 71.0 years for men and 78.6 years for women in South Korea, which is longer than that of North Korea by 8.1 for men and 11.2 for women. Infant mortality rate in 1998 was 9.0 per 1,000 live births in South Korea and 54.0 in North Korea. Since being liberated from Japanese ruling in 1945, South Korea has achieved remarkable economic growth under democracy and a market economy system. On the other hand, North Korea has maintained a socialistic system. North Korea has suffered from economic crisis since the 1990s. From this point it could be said that economic status is the major factor for the differences in health level between the two Koreas. Economic status not only directly influences health level but also indirectly affects it through influences on nutrition, hygiene, health resources, and other intervening factors. The South Korean government has concentrated its limited resources on public health activities such as tuberculosis control, family planning (FP), and maternal and child health (MCH) programmes whereas the private sector has taken charge of constructing the health delivery system including health facilities and human resources. In order to solve the problem, which might occur in the private-oriented medical care system, the South Korean government has introduced the national health insurance programme and enforced regulation policies. Many developing countries which are suffering from poverty and disease, can learn from the experience of Korea that had suffered from similar problems up to the early 1970s.

Gamisoyo-San (GSS) is a well-known Traditional Korean Medicine shown to be effective on mood disorders. The purpose of this research is to examine the effect of Gamisoyo-San on generalized anxiety disorder by its differently manufactured preparations. Multicenter, randomized, double-blinded, placebo-controlled study was set for 147 patients with generalized anxiety disorder recruited from November 1st 2009 to December 16th 2010. They were given Gamisoyo-San individual extract mixture (extraction done for each crude materia medica separately) or Gamisoyo-San multi-compound extract (extraction done for whole materia medica at once) or controlled medication. Hamilton Rating Scale for Anxiety (HAM-A), Korean State-Trait Anxiety Inventory (K-STAI), Penn State Worry Questionnaire (PSWQ), Korean Beck Depression Inventroy (K-BDI), Symptom Checklist-90-Revised (SCL-90-R), and Korean WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF) were evaluated. We also applied Pattern Identification tool for 'JingJi and ZhengChong (, Traditional Korean Medicine term which correlates with generalized anxiety disorder)' to patients to evaluate different responses among 9 patterns. HAM-A scores of Gamisoyo-San multi-compound extract group showed greater decrease compared to Gamisoyo-San individual extract mixture group and placebo group, but the difference was insignificant. WHOQOL-BREF scores of Gamisoyo-San multi-compound extract group showed significant increase compared to Gamisoyo-San individual extract mixture group and placebo group. In Heart blood deficiency pattern, the Gamisoyo-San multi-compound extract group showed significant decrease in K-BDI compared to the Gamisoyo-San individual extract mixture group. Gamisoyo-San did not improve anxiety level of GAD patients. However, it can be useful to improve quality of life, and reduce depressive, obsessive-compulsive, somatic symptoms of generalized anxiety disorder. Gamisoyo-San multi-compound seemed more effective than Gamisoyo-San individual extract mixture, especially in Heart blood deficiency pattern. Copyright © 2014 Elsevier Ireland Ltd.

Objective Serum prostate-specific antigen (PSA) may be elevated in healthy men with systemic inflammation. We aimed to investigate the association between systemic inflammation markers and serum PSA in a healthy Korean population. Material and methods A cohort of 20,151 healthy native Korean men without prostate disease between the ages of 40 and 65 years who underwent medical checkups were studied from January 2007 to December 2013. Serum total PSA and serum C-reactive protein concentrations, neutrophil, lymphocyte, and platelet counts were determined. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were calculated. We checked the correlation between systemic inflammation markers and PSA. Results Data obtained from 18,800 healthy men were analyzed. The mean age of the study subjects was 50.72±7.62 years and the mean NLR was 1.764±0.804. Correlation analysis after adjustment for age and body mass index (BMI) revealed that neutrophil count (coefficient = 0.028, p value <0.001), and NLR (coefficient = 0.027, p value <0.001) correlated with PSA. Multivariate analysis using the full model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.043 respectively). Multivariate analysis using a stepwise model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.040, respectively) and BMI was negatively correlated with PSA (p<0.001). Conclusion Systemic inflammation markers are useful with a serum PSA in a healthy Korean population. NLR in particular is significantly associated with serum PSA. PMID:28861299

To describe the longitudinal characteristics of unintentional fall accidents using a representative population-based sample of Korean adults. We examined data from the Korean Community Health Survey from 2008 to 2013. Univariate analysis and multivariable logistic regression were used to identify the characteristics of fall accidents in adults. Between 2008 and 2013, the incidence rate of fall accidents requiring medical treatment increased from 1,248 to 3,423 per 100,000 people (p<0.001), while the proportion of indoor fall accidents decreased from 38.12% to 23.16% (p<0.001). Females had more annual fall accidents than males (p<0.001). The major reason for fall accidents was slippery floors (33.7% in 2011 and 36.3% in 2013). Between 2008 and 2010, variables associated with higher fall accident risk included specific months (August and September), old age, female gender, current drinker, current smoker, diabetes, osteoarthritis, osteoporosis, and depression. A high level of education and living with a partner were negatively associated with fall accident risk. In 2013, people experiencing more than 1 fall accident felt more fear of falling than those having no fall accidents (odds ratio [OR] for 1 fall, 2.12; 95% confidence interval [CI], 2.04-2.12; OR for more than 2 falls, 2.97; 95% CI, 2.83-3.10). The occurrence of fall accidents has consistently increased in Korea from 2008 to 2013. Future intervention studies are needed to reduce the increasing incidence rates of fall accidents in community dwelling adults.

Colorectal cancer incidence is rapidly rising in many Asian countries, with rates approaching those of Western countries. This study aimed to evaluate the prevalence and trends of colorectal adenomas by age, sex, and risk strata in asymptomatic Koreans. Cross-sectional study of 19,372 consecutive participants aged 20 to 79 years undergoing screening colonoscopy at the Center for Health Promotion of the Samsung Medical Center in Korea from January 2006 to June 2009. Among participants at average risk, those without a history of colorectal polyps or a family history of colorectal cancer, the prevalence of colorectal adenomas and advanced adenomas were 34.5% and 3.1%, respectively, in men and 20.0% and 1.6%, respectively, in women. The prevalence of adenomas increased with age in both men and women, with a more marked increase for advanced adenoma. Participants with a family history of colorectal cancer or with a history of colorectal polyps had significantly higher prevalence of adenomas compared with participants of average risk (36.9% vs. 26.9%; age- and sex-adjusted prevalence ratio = 1.16; 95% confidence interval, 1.09-1.22). The prevalence of adenomas increased annually in both men and women. In this large study of asymptomatic Korean men and women participating in a colonoscopy screening program, the prevalence of colorectal adenomas was comparable and possibly higher than previously reported in Western countries. Cost-effectiveness studies investigating the optimal age for starting colonoscopy screening and etiological studies to identify the reasons for the increasing trend in colorectal adenomas in Koreans are needed. ©2014 AACR.

Owing to new advances in computer hardware, large text databases have become more prevalent than ever.Automatically mining information from these databases proves to be a challenge due to slow pattern/string matching techniques. In this paper we present a new, fast multi-string pattern matching method based on the well known Aho-Chorasick algorithm. Advantages of our algorithm include:the ability to exploit the natural structure of text, the ability to perform significant character shifting, avoiding backtracking jumps that are not useful, efficiency in terms of matching time and avoiding the typical "sub-string" false positive errors.Our algorithm is applicable to many fields with free text, such as the health care domain and the scientific document field. In this paper, we apply the BSS algorithm to health care data and mine hundreds of thousands of medical concepts from a large Electronic Medical Record (EMR) corpora simultaneously and efficiently. Experimental results show the superiority of our algorithm when compared with the top of the line multi-string matching algorithms.

The discrimination of man-made explosions from earthquakes using seismo-acoustic analysis in the Korean Peninsula

Che, Il-Young; Jeon, Jeong-Soo

2010-05-01

Korea Institute of Geoscience and Mineral Resources (KIGAM) operates an infrasound network consisting of seven seismo-acoustic arrays in South Korea. Development of the arrays began in 1999, partially in collaboration with Southern Methodist University, with the goal of detecting distant infrasound signals from natural and anthropogenic phenomena in and around the Korean Peninsula. The main operational purpose of this network is to discriminate man-made seismic events from seismicity including thousands of seismic events per year in the region. The man-made seismic events are major cause of error in estimating the natural seismicity, especially where the seismic activity is weak or moderate such as in the Korean Peninsula. In order to discriminate the man-made explosions from earthquakes, we have applied the seismo-acoustic analysis associating seismic and infrasonic signals generated from surface explosion. The observations of infrasound at multiple arrays made it possible to discriminate surface explosion, because small or moderate size earthquake is not sufficient to generate infrasound. Till now we have annually discriminated hundreds of seismic events in seismological catalog as surface explosions by the seismo-acoustic analysis. Besides of the surface explosions, the network also detected infrasound signals from other sources, such as bolide, typhoons, rocket launches, and underground nuclear test occurred in and around the Korean Peninsula. In this study, ten years of seismo-acoustic data are reviewed with recent infrasonic detection algorithm and association method that finally linked to the seismic monitoring system of the KIGAM to increase the detection rate of surface explosions. We present the long-term results of seismo-acoustic analysis, the detection capability of the multiple arrays, and implications for seismic source location. Since the seismo-acoustic analysis is proved as a definite method to discriminate surface explosion, the analysis will be continuously used for estimating natural seismicity and understanding infrasonic sources.

To investigate compliance with a viscosity-modified diet among Korean dysphagic patients and to determine which factors are associated with compliance. We retrospectively reviewed medical records of patients who had been recommended to use thickeners in the previous videofluoroscopic swallowing study (VFSS). Among 68 patients, 6 were excluded because tube feeding was required due to deterioration in their medical condition. Finally, 62 patients were included in the study. Patient compliance was assessed using their medical records by checking whether he or she had maintained thickener use until the next VFSS. To determine which factors affect compliance, the relationship between thickener use and patient characteristics, such as sex, age, inpatient/outpatient status, severity of dysphagia, aspiration symptoms, follow-up interval of VFSS, and current swallowing therapy status were assessed. For noncompliers, reasons for not using thickeners were investigated by telephone interview. Among 62 patients, 35 (56.5%) were compliers, and 27 (43.5%) were noncompliers. Eighteen (90%) of 20 inpatients had followed previous recommendations; however, only 17 (40.5%) of 42 outpatients had been using thickeners. Of patient characteristics, only admission status was significantly correlated with compliance. When asked about the reason why they had not used thickeners, noncompliers complained about dissatisfaction with texture and taste, greater difficulty in swallowing, and inconvenience of preparing meals. Among Korean dysphagic patients, compliance with a viscosity-modified liquid diet was only about 50%. Betterments of texture and taste along with patient education might be necessary to improve compliance with thickener use.

Traditional Chinese medicine (TCM), Japanese-Chinese medicine, and Korean Sasang constitutional medicine have common origins. However, the constitutional medicines of China, Japan, and Korea differ because of the influence of geographical culture, social environment, national practices, and other factors. This paper aimed to compare the constitutional medicines of China, Japan, and Korea in terms of theoretical origin, constitutional classification, constitution and pathogenesis, clinical applications and basic studies that were conducted. The constitutional theories of the three countries are all derived from the Canon of Internal Medicine or Treatise on Febrile and Miscellaneous Diseases of Ancient China. However, the three countries have different constitutional classifications and criteria. Medical sciences in the three countries focus on the clinical applications of constitutional theory. They all agree that different pathogenic laws that guide the treatment of diseases govern different constitutions; thus, patients with different constitutions are treated differently. The three countries also differ in terms of drug formulations and medication. Japanese medicine is prescribed only based on constitution. Korean medicine is based on treatment, in which drugs cannot be mixed. TCM synthesize the treatment model of constitution differentiation, disease differentiation and syndrome differentiation with the treatment thought of treating disease according to three categories of etiologic factors, which reflect the constitution as the characteristic of individual precision treatment. In conclusion, constitutional medicines of China, Japan, and Korea have the same theoretical origin, but differ in constitutional classification, clinical application of constitutional theory on the treatment of diseases, drug formulations and medication.

Wireless technologies and vehicle-mounted or wearable medical sensors are pervasive to support ubiquitous healthcare applications. However, a critical issue of using wireless communications under a healthcare scenario rests at the electromagnetic interference (EMI) caused by radio frequency transmission. A high level of EMI may lead to a critical malfunction of medical sensors, and in such a scenario, a few users who are not transmitting emergency data could be required to reduce their transmit power or even temporarily disconnect from the network in order to guarantee the normal operation of medical sensors as well as the transmission of emergency data. In this paper, we propose a joint power and admission control algorithm to schedule the users' transmission of medical data. The objective of this algorithm is to minimize the number of users who are forced to disconnect from the network while keeping the EMI on medical sensors at an acceptable level. We show that a fixed point of proposed algorithm always exists, and at the fixed point, our proposed algorithm can minimize the number of low-priority users who are required to disconnect from the network. Numerical results illustrate that the proposed algorithm can achieve robust performance against the variations of mobile hospital environments.

Medication algorithms for the treatment of depression are designed to optimize both treatment implementation and the appropriateness of treatment strategies. Thus, they are essential tools for treating and avoiding refractory depression. Treatment algorithms are explicit treatment protocols that provide specific therapeutic pathways and decision-making tools at critical decision points throughout the treatment process. The present article provides an overview of major projects of algorithm research in the field of antidepressant therapy. The Berlin Algorithm Project and the Texas Medication Algorithm Project (TMAP) compare algorithm-guided treatments with treatment as usual. The Sequenced Treatment Alternatives to Relieve Depression Project (STAR*D) compares different treatment strategies in treatment-resistant patients.

Basics of particle therapy I: physics

With the advance of modern radiation therapy technique, radiation dose conformation and dose distribution have improved dramatically. However, the progress does not completely fulfill the goal of cancer treatment such as improved local control or survival. The discordances with the clinical results are from the biophysical nature of photon, which is the main source of radiation therapy in current field, with the lower linear energy transfer to the target. As part of a natural progression, there recently has been a resurgence of interest in particle therapy, specifically using heavy charged particles, because these kinds of radiations serve theoretical advantages in both biological and physical aspects. The Korean government is to set up a heavy charged particle facility in Korea Institute of Radiological & Medical Sciences. This review introduces some of the elementary physics of the various particles for the sake of Korean radiation oncologists' interest. PMID:22984664

This study explored whether and how childhood cancer survivors in Korea ask and resolve the question of what may have caused their cancer. Thirty-one childhood cancer survivors participated in in-depth interviews about their self-questioning process in this regard. The findings indicate that Korean childhood cancer survivors pondered this question alone due to the stigma attached to cancer in the family and society. Their answers included internal factors (doing "bad things," having unhealthy eating habits, engaging in magical thinking, having a stress-prone personality, or having a biological susceptibility) or external factors (stressors, random events, the environment, or medical conditions). How they perceived the cause of cancer had an impact on aspects of their current lives. Psychosocial care standards or guidelines are needed in regard to the provision of a safe environment in which Korean cancer survivors and their parents can share their perceptions and process their thoughts.

The main objective of this study was to assess the prevalence of lower back pain (LBP) and clarify the effect of work-related psychological factors on LBP. Nationwide survey data collected from male Korean firefighters (FIFS) were used. To identify the risk factors (work-related psychological factors such as job stress and depression) affecting LBP, the χ 2 test and multivariate logistic regression analyses were conducted. The prevalence of LBP was 19.3% and was highest in the emergency medical service (31.8%) part of FF job types. Within job stress, an uncomfortable physical environment, high mental job demand and organizational injustice were associated with LBP. However, inadequate social support inversely associated with LBP. Depression and high-risk alcohol drinking were related to LBP. LBP was closely related to job stress, depression and alcohol intake. Proper interventions of psychological factors should therefore be addressed to control LBP in FIFS.

A first step toward understanding patient safety

PubMed Central

2016-01-01

Patient safety has become an important policy agenda in healthcare systems since publication of the 1999 report entitled "To Err Is Human." The paradigm has changed from blaming the individual for the error to identifying the weakness in the system that led to the adverse events. Anesthesia is one of the first healthcare specialties to adopt techniques and lessons from the aviation industry. The widespread use of simulation programs and the application of human factors engineering to clinical practice are the influences of the aviation industry. Despite holding relatively advanced medical technology and comparable safety records, the Korean health industry has little understanding of the systems approach to patient safety. Because implementation of the existing system and program requires time, dedication, and financial support, the Korean healthcare industry is in urgent need of developing patient safety policies and putting them into practice to improve patient safety before it is too late.

Objective This study aims to provide the information of the stigmas of mental illness such as psychosis, alcoholism, attempt suicide, and depression among North Korean defectors. Methods We examined stigma for the mental illnesses of 639 North Korean defectors aged 19 to 65 years who live in the Settlement Support Center for North Korean Refugees. The stigmas of mental illnesses were assessed using the Perceived Devaluation-Discrimination Scale We directly compared the stigma level between North Korean defectors and the general population of South Korea. Results North Korean defectors had higher perceived stigmas of psychosis and alcoholism and lower perceived stigmas of depression than South Koreans. Perceived stigma associated with attempted suicide was similar for North Korean defectors and South Koreans. Only marital status in sociodemographic variables had associations with higher perceived stigma of psychosis, alcoholism, and depression in the North Korean defectors. North Korean defectors, who spent more than one year in transit country, had associations with lower perceived stigma of psychosis and alcoholism. North Korean defectors, who had the experience of compulsory repatriation to North Korea or North Korean family in South Korea, had an association with higher perceived stigma of depression. Conclusion North Korean defectors had higher perceived stigmas of psychosis and alcoholism and lower perceived stigmas of depression than South Koreans. Further studies are needed to document serial changes in stigmas for mental illnesses associated with the receipt of education at the Settlement Support Center for North Korean defectors.

2004-01-01

To estimate the direct medical costs of chronic hepatitis B (CHB) infection and its liver disease sequelae in South Korea. Korea is a hepatitis B-endemic area with 5.79% to 10.87% of males and 1.51% to 4.44% of females over 20 years of age carrying the virus. It is estimated that 25% of carriers will develop serious hepatitis B virus (HBV)-related complications. While vaccination programs have reduced the prevalence of hepatitis B in people younger than 20 years, significant CHB-related morbidity will continue to occur for the next 15 to 30 years until the benefits of the vaccination programs take effect. Direct medical costs for six CHB-related disease states, including hepatocellular carcinoma and liver transplant, were estimated for the year 2001. Four data sources were used to gather information: the National Health Insurance Corporation database, patients' medical charts, expert opinion, and patient survey data. In 2001, the total medical costs of six CHB-related diseases were 250 million Korean Won (KRW) (equivalent to U.S. 208.6 million dollars), based on an exchange rate of KRW 1200 = US 1 dollar. Annual treatment costs per patient ranged from KRW297,392 (US 248 dollars) for chronic hepatitis B to KRW 80.6 million (U.S. 67,156 dollars) for liver transplant. The cost of treatment rose continuously with liver disease progression. The main cost driver was inpatient hospitalizations (including surgical costs). CHB-related diseases are a significant cost burden to the South Korean healthcare system. In addition to the obvious clinical benefits, the prevention or delay of chronic hepatitis B liver disease progression in South Korea could result in substantial economic benefits to the whole society.

The aim of this study was to identify the different influencing patterns of demographic and epilepsy-related variables on various aspects of psychosocial function in pediatric epilepsy. Five hundred ninety-eight patients with pediatric epilepsy between the ages of 4 and 18 years (boys=360, 60% and girls=238, 40%) and their parents participated in the study. Parents completed the Social Maturity Scale (SMS), the Korean version of the Child Behavior Checklist (K-CBCL), and the Korean version of the Quality of Life in Childhood Epilepsy Questionnaire (K-QOLCE) to assess daily living function, behavior, and quality of life. The Children's Global Assessment Scale (CGAS) was completed by clinicians to assess general adaptive function. Demographic variables, such as age and sex of child, and epilepsy-related clinical variables, including seizure type, seizure frequency, duration of epilepsy, and number of medications, were obtained from medical records. Demographic and epilepsy-related clinical variables had a strong influence (22-32%) on the cognition-related domain such as general adaptive function, school/total competence, and quality of life for cognitive function while a comparatively smaller effect (2-16%) on the more psychological domain including behavioral, emotional, and social variables. Younger age, shorter duration of illness, and smaller number of medications showed a strong positive impact on psychosocial function in pediatric epilepsy, particularly for adaptive function, competence, and quality-of-life aspects. Given the wide range of impact of demographic and clinical variables on various facets of psychosocial functions, more specific understanding of the various aspects of factors and their particular pattern of influence may enable more effective therapeutic approaches that address both the medical and psychological needs in pediatric epilepsy.

Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is defined as having both features of asthma and COPD, which are airway hyper-responsiveness and incompletely reversible airway obstruction. However, socioeconomic impact of ACOS have not been well appreciated. Adults with available wheezing history and acceptable spirometry were selected from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV) in 2007-2009. Their data were merged with the Korean National Health Insurance claim data. 'Asthma group' was defined as having self-reported wheezing history and FEV 1 /FVC ≥0.7, 'COPD group' was defined as having FEV 1 /FVC <0.7 and no wheezing, 'ACOS group' was defined as having both wheezing and FEV 1 /FVC <0.7, and 'no airway disease (NAD) group' was defined as having no wheezing and FEV 1 /FVC ≥0.7. Among a total of 11,656 subjects, ACOS comprise 2.2%; COPD, 8.4%; asthma, 5.8% and NAD, 83.6%. Total length of healthcare utilization and medical costs of ACOS group was the top among four groups (P<0.001), though inpatient medical cost was the highest in COPD group (P=0.025). Multiple linear regression analyses showed that ACOS group (β=12.63, P<0.001) and asthma group (β=6.14, P<0.001) were significantly associated with longer duration of healthcare utilization and ACOS group (β=350,475.88, P=0.008) and asthma group (β=386,876.81, P<0.001) were associated with higher medical costs. This study demonstrated that ACOS independently influences healthcare utilization after adjusting several factors. In order to utilize limited medical resources efficiently, it may be necessary to find and manage ACOS patients.

PHENOMENON: Medical ethics and professionalism are fundamental competencies for all physicians, and resident physicians have to develop these competencies during their training. Although Korea has a reputation for having the highest quality medical practice in East Asia, improvements in the technological aspects of care have outpaced the developments in institutional systems and education needed to fulfill social responsibility. Enhancing professionalism education during postgraduate training requires thorough exposition of this situation. Twenty residents from 17 clinical departments at 1 Korean tertiary university-affiliated hospital were recruited, and in-depth interviews were conducted in person by an interviewer who was a fellow resident with participants. Interviewees recalled and described personal experiences or observations of misbehaviors that had occurred during their residency training. Researchers recorded and transcribed all interviews, and 4 researchers conducted a thematic analysis. Authors extracted 48 descriptors representing 8 categories of unethical and unprofessional behaviors from the transcripts: (a) substandard practice, (b) violation of work ethics, (c) misconduct related to conflict of interest, (d) dishonesty with patients, (e) violation of patient confidentiality, (f) lack of respect for patients, (g) lack of respect for colleagues, and (h) misconduct in research. Each of the interviewees mentioned between 3 and 18 descriptors. "Not fulfilling basic duties for patient care" was the most frequently mentioned misconduct, followed by "fabricating patient medical status or test results to meet preoperative criteria for anesthesia" and "verbal or physical abuse of junior doctors." INSIGHTS: Residents reported a diverse variety of unethical and unprofessional behaviors throughout their training and described the ethical distress they suffered in the real clinical situations. The results of this study support the notion that reinforcing ethics and professionalism education during postgraduate medical training in a practical and authentic way will help trainees manage the ethical conflicts or dilemmas they will inevitably encounter.

Few studies have compared health behaviors of Koreans in their home country and Korean Americans. Using 2009 data from the Community Health Survey (South Korea) and the California Health Interview Survey (USA), we compared native Koreans and Korean Americans, grouped by level of acculturation, on prevalence of specific health behaviors and self-rated health, and conducted multiple logistic regression comparing the odds of these behaviors among the groups adjusted for demographic variables. While Korean Americans exhibit healthier behaviors than Koreans in some areas (e.g., reduced smoking and binge drinking in men, increased utilization of flu vaccinations), we also identified problem behaviors (e.g., increased body weight in Korean American men, uptake of alcohol drinking and smoking among Korean American women). Findings support the critical need for health promotion programs addressing these health behaviors to prevent future health problems among Korean Americans.

In 1995, the South Korean government made nutrition labeling compulsory, which has positively impacted patients with certain chronic diseases, such as dyslipidemia. We investigated the association between nutrition labeling-based awareness and the risk of dyslipidemia among individuals not yet diagnosed. Our study used data from the fifth Korea National Health and Nutrition Examination Surveys administered during 2010-2014 (n = 17,687). We performed multiple or logistic regression analysis to examine the association between nutritional analysis and various outcome variables. Approximately 70 % of the respondents (n = 11,513) were familiar with nutrition labeling, of which 20 % (n = 3172) decided what food to buy based on that information. This awareness yielded mostly positive results on outcome indicators, such as triglyceride and high-density lipoprotein cholesterol levels. In general, individuals who used nutritional labels to make decisions regarding food purchases had a lower risk of dyslipidemia than individuals who did not (OR: 0.806, 95 % CI: 0.709-0.917). Utilizing nutrition labels for making food choices correlated with a lower risk of dyslipidemia in certain subgroups. Based on our findings, we recommend that health policymakers and medical professionals consider promoting nutrition labeling as an alternative method for managing certain chronic diseases in South Korean patients.

To determine the relations between post-stroke aphasia severity and aphasia type and lesion location, a retrospective review was undertaken using the medical records of 97 Korean patients, treated within 90 days of onset, for aphasia caused by unilateral left hemispheric stroke. Types of aphasia were classified according to the validated Korean version of the Western Aphasia Battery (K-WAB), and severities of aphasia were quantified using WAB Aphasia Quotients (AQ). Lesion locations were classified as cortical or subcortical, and were determined by magnetic resonance imaging. Two-step cluster analysis was performed using AQ values to classify aphasia severity by aphasia type and lesion location. Cluster analysis resulted in four severity clusters: 1) mild; anomic type, 2) moderate; Wernicke's, transcortical motor, transcortical sensory, conduction, and mixed transcortical types, 3) moderately severe; Broca's aphasia, and 4) severe; global aphasia, and also in three lesion location clusters: 1) mild; subcortical 2) moderate; cortical lesions involving Broca's and/or Wernicke's areas, and 3) severe; insular and cortical lesions not in Broca's or Wernicke's areas. These results revealed that within 3 months of stroke, global aphasia was the more severely affected type and cortical lesions were more likely to affect language function than subcortical lesions.

Several clinical risk factors for low bone mineral density (BMD) in the patients with inflammatory bowel disease (IBD) have been suggested. However, its prevalence and pathophysiology in Korean population have not been fully studied. The aim of this study was to investigate the prevalence and risk factors for low BMD in Korean IBD patient. BMD of the lumbar spine and femur was evaluated using dual-energy X-ray absorptiometry in 30 patients with IBD. Biochemical parameters of bone metabolism, such as serum calcium, phosphorus, osteocalcin, and deoxypyridinoline were measured. The associations between low BMD and clinical parameters such as disease duration, disease activity, drug history, body mass index (BMI), and others were evaluated retrospectively using medical records. Low BMD at the lumbar spine or femur was observed in 63.3% of the patients, and there was no significant difference between the patients with Crohns disease and ulcerative colitis. Clinical and biochemical parameters were irrelevant to BMD. In the patients without glucocorticoid treatment prior to BMD measurement, already 50.0% of patients had low BMD. Low BMD is a common feature in Korean IBD patients, even those who do not use glucocorticoid. The multiple factors may be involved in the pathogenesis of low BMD. Therefore, BMD should be examined in all IBD patients, irrespective of glucocorticoid treatment.

Objective This study aimed to investigate the current data regarding age, sex, and Angle Classification of Korean orthodontic patients and influence of these factors on the tendency to undergo extraction and orthognathic surgery. Methods The recent trends of Korean orthodontic patients were assessed using questionnaire survey. The questionnaires were e-mailed to orthodontists who met the study criteria; 58% of the orthodontists opened the e-mails, and 27.7% replied to the e-mails. In all, the medical records of 11,340 patients who underwent orthodontic treatment at private clinics and small dental hospitals in Korea were analyzed. Results The percentage of female patients in the study sample was 69.6%, and the average age of the patients was 19.87 years. The percentage of patients who were older than 19 years was 50.2%. Class II and Class III malocclusions were noted in 33.6% and 23.6% of patients, respectively. Extraction and orthognathic surgery were performed in 60.4% and 6.9% of patients, respectively. Conclusions The results showed that there were a high percentage of adult, Class II malocclusion and extraction patients in private practices and small dental hospitals during the study period. Further, a relatively high proportion of adult patients opted to undergo orthognathic surgery. PMID:23112936

This study aimed to evaluate the frequency and clinical characteristics of hydroxychloroquine (HCQ) retinopathy in Korean patients with rheumatologic diseases. We retrospectively reviewed medical records of 310 patients taking HCQ. Ophthalmic examinations included spectral-domain optical coherence tomography (SD-OCT), automated visual field test, and fundus autofluorescence. The severity of retinopathy was categorized as early, moderate, or severe, and the location was categorized as parafoveal, pericentral, or mixed pattern. Among 310 patients, 9 patients (2.9%) were diagnosed as HCQ retinopathy. Among the patients with HCQ use ≥ 5 years (n = 174), the frequency was 5.2%. Only 1 (11.1%) of the 9 patients was symptomatic. The mean daily dose per kilogram of real body weight of the 9 patients was 5.6 mg, and only 3 had used 6.5 mg or more. Four of the 9 patients had severe HCQ retinopathy. Six of the 9 patients showed pericentral or mixed pattern of retinal damage. Consequently, the frequency of HCQ retinopathy in Korean patients was not low, especially when administered at a high cumulative dose and for a long duration. Screening of HCQ retinopathy by the recommended guidelines that include SD-OCT seems useful and should be done to detect retinal damage earlier in patients with chronic exposure to HCQ.

[Purpose] The purpose of this study was to investigate the association between psychosocial stress, occupational stress, and musculoskeletal symptoms in Korean dental practitioners. [Subjects and Methods] Self-reported questionnaires were distributed to 401 dental practitioners in Korea. To assess the risk factors related to musculoskeletal disorders, the Nordic Musculoskeletal Questionnaire, the Korean Occupational Stress Scale, and Psychosocial Well-Being Index Short Form were used. General and work-related characteristics of the subjects consisted of seven items, including age, career, height, weight, working days/week, working hours/day, and physical strain levels. [Results] In this study, 86.8% of the practitioners experienced musculoskeletal symptoms (shoulders, 72.8%; neck, 69.3%; waist, 68.3%; wrist, 58.4%; back, 44.1%; ankle, 38.7%; knee, 36.9%; hip, 20.4%; and elbows, 9.2%). Moreover, psychosocial and occupational stress can affect the occurrence of musculoskeletal disorders. In particular, we found that psychosocial stress has significant influence on the occurrence of musculoskeletal disorders. [Conclusion] To increase the quality of life and provide high-quality medical service for dental practitioners, risk factors for musculoskeletal disorders must be managed. Accordingly, dental practitioners must maintain good posture, get an appropriate amount of rest, and perform regular stretching exercise to reduce psychological stress and improve the work environment.

This study aimed to investigate the mammography rate and its demographic correlates among Korean women in order to provide basic understanding of factors related to the performance of mammography as a method of breast cancer screening. A descriptive secondary analysis was conducted using a national data set from the Korean National Health and Nutrition Examination Survey (KNHNES III) in South Korea. A total number of 2,602 women over 40 years of age were chosen for the analysis. Main research variables included the use of mammography, monthly income, residential area, age, marriage, education, insurance, smoking habits, drinking habits, job type, current health status, and other cancer screening results. Only 30.59% of women adhered to the national guidelines. Monthly income, age, education, insurance, and smoking habits had statistically significant effects on breast cancer screening performance. The demographic correlates of the performance of mammography highlight the fact that not all Korean women, at this stage, are in a socioeconomic or societal position to undergo biannual mammography screening. Targeted and tailored nursing intervention should be implemented in middle- and senior-aged women who lack the ability to access medical resources in South Korea. This will make it possible for marginalized women to utilize cancer screening tests and in turn promote their health.

The Illness Intrusiveness Rating Scale (IIRS) measures illness-induced disruptions to 13 domains of lifestyles, activities, and interests. A stable three-factor structure has been well documented; however, the cross-cultural validity of this scale needs to be tested. This study investigated the factor structure of the Korean version of IIRS in 712 outpatients at a university medical center. A predominant diagnosis of the patients was rheumatoid arthritis (47%). The Center for Epidemiological Studies-Depression Scale (CES-D), and Health Assessment Questionnaire (HAQ) were also administered. Exploratory Principal Component Analysis identified a two-factor structure, "Relationships and Personal Development (RPD)" and "Instrumental", accounting for 57% of the variance. Confirmatory analyses extracted an identical factor structure. However, a goodness-of-the fit test failed to support two-factor solution (χ2=138.2, df=43, p<.001). Two factors had high internal consistency (RPD, α=.89; Instrumental, α=.75) and significantly correlated with scores of HAQ (RPD, r=.53, p<.001; Instrumental, .r=44, p<.001) and CES-D (RPD, .r=55, p<.001; Instrumental, .r=43, p<.001). These findings supported construct validity of the Korean version of IIRS, but did not support cross-cultural equivalence of the factor structure. PMID:15832005

The purpose of this study was to examine differences in participation motivation and competition anxiety between Korean and non-Korean wheelchair tennis players and to identify relations between participation motivation and competition anxiety in each group. Sixty-six wheel-chair tennis players who participated in the 2013 Korea Open Wheel-chair Tennis Tournament in Seoul completed the Participation Motivation Survey and the Competitive State Anxiety Inventory II. Data were analyzed by a frequency analysis, descriptive statistics, Pearson’s correlation analysis, and independent samples t-test to identify participants’ demographic characteristics, differences in participation motivation, competition anxiety between Korean and non-Korean players, and correlations between participation motivation and competition anxiety in each group. Korean players reported significantly higher motivation in purification compared to non-Korean players, whereas non-Korean players reported significantly higher motivation in enjoyment. In addition, non-Korean players demonstrated higher cognitive anxiety and self-confidence compared to Korean players. Moreover, the physical anxiety of Korean players was negatively correlated with learning, health-fitness, and enjoyment motivation. On the other hand, only self-confidence was significantly related to learning motivation and enjoyment motivation in non-Korean players. Thus, the results presented herein provide evidence for the development of specialized counseling programs that consider the psychological characteristics of Korean wheelchair tennis players.

The nonrigid registration algorithm based on B-spline Free-Form Deformation (FFD) plays a key role and is widely applied in medical image processing due to the good flexibility and robustness. However, it requires a tremendous amount of computing time to obtain more accurate registration results especially for a large amount of medical image data. To address the issue, a parallel nonrigid registration algorithm based on B-spline is proposed in this paper. First, the Logarithm Squared Difference (LSD) is considered as the similarity metric in the B-spline registration algorithm to improve registration precision. After that, we create a parallel computing strategy and lookup tables (LUTs) to reduce the complexity of the B-spline registration algorithm. As a result, the computing time of three time-consuming steps including B-splines interpolation, LSD computation, and the analytic gradient computation of LSD, is efficiently reduced, for the B-spline registration algorithm employs the Nonlinear Conjugate Gradient (NCG) optimization method. Experimental results of registration quality and execution efficiency on the large amount of medical images show that our algorithm achieves a better registration accuracy in terms of the differences between the best deformation fields and ground truth and a speedup of 17 times over the single-threaded CPU implementation due to the powerful parallel computing ability of Graphics Processing Unit (GPU).

Medical visualization and analysis of medical data is an actual direction. Medical images are used in microbiology, genetics, roentgenology, oncology, surgery, ophthalmology, etc. Initial data processing is a major step towards obtaining a good diagnostic result. The paper considers the approach allows an image filtering with preservation of objects borders. The algorithm proposed in this paper is based on sequential data processing. At the first stage, local areas are determined, for this purpose the method of threshold processing, as well as the classical ICI algorithm, is applied. The second stage uses a method based on based on two criteria, namely, L2 norm and the first order square difference. To preserve the boundaries of objects, we will process the transition boundary and local neighborhood the filtering algorithm with a fixed-coefficient. For example, reconstructed images of CT, x-ray, and microbiological studies are shown. The test images show the effectiveness of the proposed algorithm. This shows the applicability of analysis many medical imaging applications.

Colorectal cancer among Koreans living in South Korea versus California: incidence, mortality, and screening rates.

This study compared trends in colorectal cancer (CRC) incidence and mortality rates among Koreans in South Korea and Korean Americans and non-Hispanic whites in California between 1999 and 2009, and examined CRC screening rates and socio-demographic correlates of CRC screening in the two Korean populations. Age-standardized CRC incidence and mortality rates of Koreans in South Korea and Korean Americans and non-Hispanic whites in California for the years 1999-2009 were obtained from annual reports of cancer statistics and modeled using joinpoint regression. Using 2009 data from the Korean National Health and Nutrition Examination Survey and the California Health Interview Survey, we estimated and compared CRC screening rates and test modalities. We used multiple logistic regression to examine socio-demographic correlates of completion of CRC screening according to the guidelines among the two Korean populations. CRC incidence and mortality rates among South Koreans increased during 1999-2009 but more slowly during the late 2000s. In California, CRC incidence increased among Korean American females but decreased among non-Hispanic whites. About 37% of South Koreans and 60% of Korean Americans reported completion of CRC screening according to guidelines in 2009. Among South Koreans, married status, higher income, and private health insurance were associated with CRC screening, adjusting for other factors. Among Korean Americans, having health insurance was associated with CRC screening. Despite almost identical CRC screening guidelines in South Korea and the USA and substantially higher screening rates among Korean Americans as compared to South Koreans, disparities remain in both populations with respect to CRC statistics. Thus, efforts to promote primary and secondary prevention of CRC in both Korean populations are critically important in both countries.

Analysis of the prevalence of and factors associated with overactive bladder in adult Korean women

2017-01-01

Background Overactive bladder (OAB) is one of the most prevalent lower urinary tract conditions and has been suggested to be related to various factors. We assessed the prevalence of and factors associated with OAB in women based on a large cross-sectional, population-based study of adult Korean women. Methods The Korean community health survey (KCHS) of 2012 was reviewed, and 107,950 female participants aged 19 to 107 years were identified for inclusion in this study. The overactive bladder symptom score (OABSS) was used to define and classify OAB as mild, moderate, or severe. Numerous variables, including marital status; physical activity; education and income levels; type of occupation; body mass index (BMI); smoking; alcohol; sleep time; and medical history of hypertension, diabetes mellitus, hyperlipidemia, or cerebral stroke, were evaluated. The correlation of these variables with the prevalence of OAB was analyzed using simple and multiple logistic regression analyses with complex sampling. Results The results showed that 5.2% of adult women experienced OAB. Multiple regression analyses showed a significant correlation between the following variables and OAB: older age (adjusted odds ratio [AOR] = 1.44, 95% confidence interval [CI] = 1.39–1.50, P < 0.001 as 10 years older); married status (AOR = 0.83, 95%CI = 0.70–0.96, P = 0.016); lower level of income (AOR = 1.50, 95%CI = 1.34–1.68, P < 0.001); high BMI (AOR = 1.33, 95%CI = 1.23–1.44, P < 0.001); smoking (AOR = 1.24, 95%CI = 1.04–1.47, P < 0.001); long sleep time (AOR = 1.95, 95%CI = 1.69–2.26); and medical history of hypertension (AOR = 1.11, 95%CI = 1.03–1.21, P = 0.011), diabetes mellitus (AOR = 1.38, 95%CI = 1.25–1.53, P < 0.001), hyperlipidemia (AOR = 1.27, 95%CI = 1.16–1.39, P < 0.001), and cerebral stroke (AOR = 2.04, 95%CI = 1.73–2.41, P < 0.001). The level of stress showed a dose-dependent association with OAB (AOR [95%CI] = 3.28 [2.81–3.83] > 2.11 [1.91–2.33] >1.28 [1.16–1.41] for severe > moderate > some stress, respectively, P < 0.001). Conclusion The prevalence of OAB was approximately 5.2% among adult Korean women. Older age; high BMI; stress level; sleep duration; levels of income and education; marital status; smoking; and medical history of hypertension, diabetes mellitus, hyperlipidemia, and cerebral stroke were significantly related to OAB in women.

Current trends in medicine, specifically in the electronic handling of medical applications, ranging from digital imaging, paperless hospital administration and electronic medical records, telemedicine, to computer-aided diagnosis, creates a burden on the network. Distributed Service Architectures, such as Intelligent Network (IN), Telecommunication Information Networking Architecture (TINA) and Open Service Access (OSA), are able to meet this new challenge. Distribution enables computational tasks to be spread among multiple processors; hence, performance is an important issue. This paper proposes a novel approach in load balancing, the Random Sender Initiated Algorithm, for distribution of tasks among several nodes sharing the same computational object (CO) instances in Distributed Service Architectures. Simulations illustrate that the proposed algorithm produces better network performance than the benchmark load balancing algorithms-the Random Node Selection Algorithm and the Shortest Queue Algorithm, especially under medium and heavily loaded conditions.

The consensus algorithm for the medical management of type 2 diabetes was published in August 2006 with the expectation that it would be updated, based on the availability of new interventions and new evidence to establish their clinical role. The authors continue to endorse the principles used to develop the algorithm and its major features. We are sensitive to the risks of changing the algorithm cavalierly or too frequently, without compelling new information. An update to the consensus algorithm published in January 2008 specifically addressed safety issues surrounding the thiazolidinediones. In this revision, we focus on the new classes of medications that now have more clinical data and experience.

Korean ginseng and mountain ginseng (Panax ginseng CA Meyer) are important traditional herbal plants whose ginsenosides are generally accepted as serving to improve sexual functions, such as penile erection. We investigated the effects of tissue-cultured mountain ginseng extract (TMGE) on male patients with erectile dysfunction (ED). A double-blind, placebo-controlled study was conducted with 143 patients experiencing ED. Over the course of 8 weeks, one group took 1 000 mg of TMGE twice a day, and the other group took 1 000 mg of placebo twice a day. The effects of the TMGE and the placebo were analyzed using the Korean version of the International Index of Erectile Function (IIEF) questionnaire. A total of 86 patients completed 8 weeks of treatment. The scores on the five domains of the IIEF after medication were significantly higher than the baseline scores in the group treated with TMGE (P < 0.05), whereas no significant improvement was observed in the placebo group (P > 0.05). Erectile function and overall satisfaction scores after medication were significantly higher in the TMGE group than in the placebo group (P < 0.05). Erectile function of patients in the TMGE-treated group significantly improved, suggesting that TMGE could be utilized for improving erectile function in male patients. PMID:19234482

To obtain fundamental information for the standardization of herbal medicine in Korea. We analyzed the herbal medicine prescription data of patients at the Pusan National University Korean Medicine Hospital from March 2010 to February 2013. We used the Dongui-Bogam (Dong Yi Bao Jian) to classify prescribed herbal medicines. The study revealed that the most frequently prescribed herbal medicine was 'Liuwei Dihuang Pill (LWDHP, )' which was used for invigorating 'Shen (Kidndy)-yin'. 'LWDHP' was most frequently prescribed to male patients aged 50-59, 60-69, 70-79 and 80-89 years, and 'Xionggui Tiaoxue Decoction (XGTXD, )' was most frequently prescribed to female patients aged 30-39 and 40-49 years. According to the International Classification of Diseases (ICD) codes, 'Diseases of the musculoskeletal system and connective tissue' showed the highest prevalence. 'LWDHP' and 'XGTXD' was the most frequently prescribed in categories 5 and 3, respectively. Based on the percentage of prescriptions for each sex, 'Ziyin Jianghuo Decoction ()' was prescribed to mainly male patients, and 'XGTXD' with 'Guima Geban Decoction ()' were prescribed to mainly female patients. This study analysis successfully determined the frequency of a variety of herbal medicines, and many restorative herbal medicines were identified and frequently administered.

In South Korea, military service is compulsory for all healthy young men and provides specific environmental factors, with groups working and living together in specific places for several years making varicella more transmissible to susceptible individuals. Studies of people serving in the South Korean military may provide information about the young adult male population in Korea. To determine the relationship between chickenpox and atopic dermatitis (AD) in young adults over a period of 3 years. The computerized database of the Armed Forces Medical Command was examined to identify the number of reported cases of chickenpox, AD, and AD associated with chickenpox. In total, 588 cases of chickenpox (183, 182 and 223 in the periods November 2004 to October 2005, November 2005 to October 2006, and November 2006 to October 2007, respectively) were reported. A greater number of patients were found to be infected with chickenpox in January and November, with fewer patients in August and September (P < 0.0001). Within the same periods, 1890, 2417 and 2779 patients diagnosed with AD were recorded in the Defense Medical Information System. Only 3 of 588 patients with chickenpox also had AD (0.5%). In this population-based study, the epidemiological trend of chickenpox and AD over a period of 3 years within the military personnel of South Korea is shown.

The goal of this study was to characterize the difficulty index of the items in the skills test components of the class I and II Korean emergency medical technician licensing examination (KEMTLE), which requires examinees to select items randomly. The results of 1,309 class I KEMTLE examinations and 1,801 class II KEMTLE examinations in 2013 were subjected to analysis. Items from the basic and advanced skills test sections of the KEMTLE were compared to determine whether some were significantly more difficult than others. In the class I KEMTLE, all 4 of the items on the basic skills test showed significant variation in difficulty index (P<0.01), as well as 4 of the 5 items on the advanced skills test (P<0.05). In the class II KEMTLE, 4 of the 5 items on the basic skills test showed significantly different difficulty index (P<0.01), as well as all 3 of the advanced skills test items (P<0.01). In the skills test components of the class I and II KEMTLE, the procedure in which examinees randomly select questions should be revised to require examinees to respond to a set of fixed items in order to improve the reliability of the national licensing examination.

The economic burden of musculoskeletal disease in Korea: A cross sectional study

PubMed Central

2011-01-01

Background Musculoskeletal diseases are becoming increasingly important due to population aging. However, studies on the economic burden of musculoskeletal disease in Korea are scarce. Therefore, we conducted a population-based study to measure the economic burden of musculoskeletal disease in Korea using nationally representative data. Methods This study used a variety of data sources such as national health insurance statistics, the Korea Health Panel study and cause of death reports generated by the Korea National Statistical Office to estimate the economic burden of musculoskeletal disease. The total cost of musculoskeletal disease was estimated as the sum of direct medical care costs, direct non-medical care costs, and indirect costs. Direct medical care costs are composed of the costs paid by the insurer and patients, over the counter drugs costs, and other costs such as medical equipment costs. Direct non-medical costs are composed of transportation and caregiver costs. Indirect costs are the sum of the costs associated with premature death and the costs due to productivity loss. Age, sex, and disease specific costs were estimated. Results Among the musculoskeletal diseases, the highest costs are associated with other dorsopathies, followed by disc disorder and arthrosis. The direct medical and direct non-medical costs of all musculoskeletal diseases were $4.18 billion and $338 million in 2008, respectively. Among the indirect costs, those due to productivity loss were $2.28 billion and costs due to premature death were $79 million. The proportions of the total costs incurred by male and female patients were 33.8% and 66.2%, respectively, and the cost due to the female adult aged 20-64 years old was highest. The total economic cost of musculoskeletal disease was $6.89 billion, which represents 0.7% of the Korean gross domestic product. Conclusions The economic burden of musculoskeletal disease in Korea is substantial. As the Korean population continues to age, the economic burden of musculoskeletal disease will continue to increase. Policy measures aimed at controlling the cost of musculoskeletal disease are therefore required. PMID:21749727

[Purpose] The purpose of this study was to develop the Korean version of the PedsQL(TM) 3.0 Cerebral Palsy Module to evaluate the health-related quality of life of children with cerebral palsy and to test the reliability and validity. [Subjects and Methods] The study included 108 caregivers of children with cerebral palsy aged 2 to 4 years and 72 caregivers of children aged 5 to 7 years, who visited multiple sites between February and August 2015. The Translation Commission performed the first translation with the approval of the Mapi Research Trust Company to create a Korean-version of the PedsQL(TM). Afterwards, back-translation was performed by one translator specializing in health and medical treatment who was a native English-speaker fluent in Korean, and one native Korean-speaker fluent in English. The consistency of each question was confirmed and a translation-integrated version was created. Test components were explained to caregivers during a one-on-one interview; caregivers then completed the PedsQL(TM) questionnaire and a Pediatric Evaluation Disability Inventory (PEDI) questionnaire. Subjects contributing to test-retest measures were asked to repeat the PedsQL questionnaire one week later and return it by mail. To assess data quality for the survey question results, non-response rate, ceiling effect, and floor effect were analyzed. Test-retest reliability and internal consistency reliability were assessed. For test-retest reliability, an intraclass correlation coefficient (ICC) was calculated, and for internal consistency reliability, Cronbach's alpha was used. To test criterion-related validity, Pearson's correlation coefficient was used. [Results] The content validity of the PedsQL 3.0 Cerebral Palsy Module was high for both age groups, and demonstrated significant internal consistency (>0.7) in all areas. For test-retest reliability, both groups demonstrated a significant ICC (>0.61). Correlation with the PEDI was statistically significant in all areas except pain and hurt. [Conclusion] The Korean version of the PedsQL(TM) 3.0 Cerebral Palsy Module was found to be reliable and valid, and is expected to contribute greatly to the evaluation of the quality of life of children with cerebral palsy.

To evaluate and analyse the factors associated with health-related quality of life (HR-QoL) in the Korean population aged 50 years and older. We used data obtained from the fourth and fifth Korea National Health and Nutrition Examination Survey (KNHANES IV-V) 2007-2012, a national, cross-sectional health examination and survey, for which representative data on the health, nutritional status, and physical activities of the Korean general population are collected by the Korea Centres for Disease Control and Prevention (KCDC). The sampling protocol for the KNHANES was designed to involve a complex, stratified, multistage probability cluster survey of a representative sample of the noninstitutionalized civilian population in South Korea using a cross-sectional design. The association between HR-QoL and socio-economic factors and medical comorbidities in adults aged 50 years and older was investigated using data from the KNHANES IV-V from 2007 to 2012 (n = 17,937). The EuroQol 5-Dimension Questionnaire (EQ-5D) was used to evaluate HR-QoL, and the factors associated with HR-QoL were analysed after adjusting for socio-economic and demographic factors, anthropometric measurements and clinical comorbidities. Health status declined with ageing, and low socio-economic status had negative associations with health status. Gender had no association with health status. Among chronic medical conditions, arthritis and depression had significant associations with health status in older people when stratified by age and gender (P < 0.05). These findings suggest that older people may value the ability to perform daily activities, which may mean that it is necessary to pay more attention to the factors associated with musculoskeletal pain and emotional distress, as well as socio-economic status or chronic diseases. The Korea National Health and Nutrition Examination Survey (KNHNES) is not a clinical trial registry, but the national health survey conducted by the Government of the Republic of Korea, to gather information on health and nutritional status of Korean population, to plan public health services and health education programs, and to do statistical studies of the efficiency of public health services required for setting up welfare and healthcare policies.

Objective We investigated the prevalence of insomnia and its clinical characteristics in North Korean refugees. Methods North Korean refugees living in South Korea (48 males, 129 females; mean age 38.22±12.24 years) and South Koreans (112 males, 203 females; mean age 39.48±10.32 years) completed the following questionnaires: the Self-reported Questionnaire on Insomnia, Center for Epidemiological Studies-Depression Scale (CES-D), Trauma Exposure Check List for North Korean Refugees, and the Impact of Event Scale-Revised (IES-R). Results North Korean refugees had insomnia more often than South Koreans did (38.42% vs. 8.89%). Depression combined with insomnia was also more prevalent in North Korean refugees (28.25% vs. 3.17%). Compared with South Koreans with insomnia, North Korean refugees with insomnia showed higher CES-D scores. The North Korean refugees with insomnia had experienced a larger number of traumatic events, and had higher CES-D and IES-R scores compared to North Korean refugees without insomnia. Insomnia in North Korean refugees was also associated with the presence of significant depressive and post-traumatic stress disorder (PTSD) symptoms. Conclusion Insomnia was common in North Korean refugees and was closely associated with depressive and PTSD symptoms. Our study suggests that complaints of insomnia may indicate more severe psychopathology, especially in refugees. PMID:26766948

Medical image segmentation using genetic algorithms.

PubMed

Maulik, Ujjwal

2009-03-01

Genetic algorithms (GAs) have been found to be effective in the domain of medical image segmentation, since the problem can often be mapped to one of search in a complex and multimodal landscape. The challenges in medical image segmentation arise due to poor image contrast and artifacts that result in missing or diffuse organ/tissue boundaries. The resulting search space is therefore often noisy with a multitude of local optima. Not only does the genetic algorithmic framework prove to be effective in coming out of local optima, it also brings considerable flexibility into the segmentation procedure. In this paper, an attempt has been made to review the major applications of GAs to the domain of medical image segmentation.

With the rapid development of modern medical imaging technology, medical image classification has become more and more important in medical diagnosis and clinical practice. Conventional medical image classification algorithms usually neglect the semantic gap problem between low-level features and high-level image semantic, which will largely degrade the classification performance. To solve this problem, we propose a multi-scale non-negative sparse coding based medical image classification algorithm. Firstly, Medical images are decomposed into multiple scale layers, thus diverse visual details can be extracted from different scale layers. Secondly, for each scale layer, the non-negative sparse coding model with fisher discriminative analysis is constructed to obtain the discriminative sparse representation of medical images. Then, the obtained multi-scale non-negative sparse coding features are combined to form a multi-scale feature histogram as the final representation for a medical image. Finally, SVM classifier is combined to conduct medical image classification. The experimental results demonstrate that our proposed algorithm can effectively utilize multi-scale and contextual spatial information of medical images, reduce the semantic gap in a large degree and improve medical image classification performance.

Objective To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors. Methods The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured questionnaire over the phone. Post-poliomyelitis syndrome (PPS) was identified according to the specified diagnostic criteria. Differences between polio survivors with or without PPS were evaluated, and the risk factors for PPS were analyzed by the odds ratio (OR). Results Majority of polio survivors were middle-aged and mean age was 51.2±8.3 years. A total of 188 out of 313 polio survivors met the adopted criteria for PPS based on the symptoms, yielding a prevalence of 61.6%. Mean interval between acute poliomyelitis and the development of PPS was 38.5±11.6 years. Female gender (OR 1.82; confidence interval [CI] 1.09-3.06), the age at onset of poliomyelitis (OR 1.75; CI 1.05-2.94), the use of orthoses or walking aids (OR 2.46; CI 1.44-4.20), and the history of medical treatment for paralysis, pain or gait disturbance (OR 2.62; CI 1.52-4.51) represented independent risk factors for PPS. Conclusion We found that the majority of Korean polio survivors entered middle age with many medical, functional, and social problems. Female gender, early age of onset of poliomyelitis, the use of orthoses or walking aids, and the history of medical treatment for paralysis, pain or gait disturbance were identified as the significant risk factors for PPS. A comprehensive and multidisciplinary plan should be prepared to manage polio survivors considering their need for health care services and the risk factors for late effects, such as PPS.

2017-03-01

This study aimed to evaluate the reliability and validity of the Korean version of the Mini-Sleep Questionnaire-Insomnia in Korean college students. A total of 470 students from six nursing colleges in South Korea participated in the study. The translation and linguistic validation of the Mini-Sleep Questionnaire-Insomnia was performed based on guidelines. The Pittsburgh Sleep Quality Index and the Perceived Stress Scale were used to validate the measure. Cronbach α, item-total correlation for internal consistency reliability and intraclass correlation coefficient for test-retest reliability were evaluated. Exploratory factor analysis for construct validity, Pearson's correlation with the Pittsburgh Sleep Quality Index and the Perceived Stress Scale for concurrent validity, and the receiver operating character curve for predictive validity were assessed. The 4-item Mini-Sleep Questionnaire-Insomnia had a Cronbach α of .69 and the item-total correlations were higher than .30. Cronbach α increased to .73 if the item assessing the use of sleeping pills and tranquilizers was deleted. This item had marked skewness and kurtosis issues. Factor analysis indicated unidimensionality, explaining 53.0% of the total variance. The measure showed high test-retest reliability (i.e., intraclass correlation coefficient = .84), acceptable concurrent validity (r with the Pittsburg Sleep Quality Index = .69; r with the Perceived Stress Scale = .31) and predictive validity [area under curve = .85; 95% confidence interval (0.81, 0.90)]. The Mini-Sleep Questionnaire-Insomnia showed acceptable reliability and validity. Yet, the limited distribution in sleep medications warrants further evaluations in the clinical population.

Metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) are differentiated by the presence of cardiometabolic risk factors (CMRFs) and insulin resistance (IR). This study aimed to evaluate the prevalence and clinical characteristics of MHO in Korean children and adolescents and to investigate the anthropometric, laboratory, and lifestyle predictors of MHO. This study included data from 530 obese subjects, aged 10-19 years, obtained from the Fourth Korea National Health and Nutrition Examination Survey. Subjects were classified into MHO and MUO groups according to the presence of CMRF (MHO(CMRF)/MUO(CMRF)) and degree of IR (MHO(IR)/MUO(IR)). Demographic, anthropometric, cardiometabolic, and lifestyle factors were compared between the groups. Logistic regression analysis and receiver operating characteristic curve analysis were performed to identify factors that predicted MHO. The prevalence of MHO(CMRF) and MHO(IR) in obese Korean youth was 36.8% (n = 197) and 68.8% (n = 356), respectively. CMRF profiles were significantly less favorable in MUO children. Longer and more vigorous physical activity and less protein intake were associated with MHO(CMRF) phenotype. The best predictors of MHO(CMRF) and MHO(IR) were waist circumference (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.77-0.88; P < 0.001) and body mass index (BMI) standard deviation score (OR, 0.24; 95% CI, 0.15-0.39; P < 0.001), respectively. The prevalence of MHO differed depending on how it was defined. To adequately manage obesity in youth, the approach to individuals with MHO and MUO should be personalized due to variation in clinical characteristics. Longitudinal studies are needed to evaluate long-term consequences of MHO. © 2017 The Korean Academy of Medical Sciences.

To estimate the prevalence and identify the predictors of depression among community-dwelling Korean American elderly (KAE). A cross-sectional descriptive epidemiological survey using a two-step sampling strategy to obtain a representative community sample. The authors recruited study participants at religious, service, and business establishments in the KA community (26 churches, 6 senior centers, 2 medical daycare centers, 1 supermarket). Community-dwelling first-generation KAE (N = 1,118; mean age ± SD: 70.5 ± 7.0 years; female: 67.2%). Trained bilingual nurses and community health workers interviewed participants face-to-face for demographic information, chronic conditions, and depression using the Korean versions of the Patient Health Questionnaire (PHQ-9K). 30.3% of KAEs were classified as having either mild (PHQ-9K score 5-9; N = 218, 19.5%) or clinical depression (PHQ-9K score ≥10; N = 120, 10.8%), respectively. One of seven KAE (N = 164, 14.7%) endorsed thoughts of death or self-injury, but only 63 (5.7%) reported utilizing mental health services. The authors also identified several predictors of depression, including living arrangement (living alone versus living with family/spouse); having chronic conditions such as diabetes, arthritis, digestive disorders, or chronic bronchitis; years of education; and cognitive impairment. The authors' findings reveal a high prevalence of depression among KAE and a low level of mental health service utilization. Because there are urgent needs for culturally and contextually relevant interventions, the authors also discuss the feasibility of community-based interventions to reduce the burden of depression, which should be incorporated into a management system for multiple chronic conditions.

2017-10-01

With widespread use of the smartphone, clinical evidence for smartphone addiction remains unclear. Against this background, we analyzed the effect of smartphone use patterns on smartphone addiction in Korean adolescents. A total of 370 middle school students participated. The severity of smartphone addiction was measured through clinical interviews and the Korean Smartphone Addiction Proneness Scale. As a result, 50 (13.5%) were in the smartphone addiction group and 320 (86.5%) were in the healthy group. To investigate the effect of smartphone use patterns on smartphone addiction, we performed self-report questionnaires that assessed the following items: smartphone functions mostly used, purpose of use, problematic use, and parental attitude regarding smartphone use. For smartphone functions mostly used, the addiction group showed significantly higher scores in "Online chat." For the purpose of use, the addiction group showed significantly higher "habitual use," "pleasure," "communication," "games," "stress relief," "ubiquitous trait," and "not to be left out." For problematic use, the addiction group showed significantly higher scores on "preoccupation," "tolerance," "lack of control," "withdrawal," "mood modification," "conflict," "lies," "excessive use," and "loss of interest." For parental attitude regarding children's smartphone use, the addiction group showed significantly higher scores in "parental punishment." Binary logistic regression analysis indicated that "female," "use for learning," "use for ubiquitous trait," "preoccupation," and "conflict" were significantly correlated with smartphone addiction. This study demonstrated that the risk factors for smartphone addiction were being female, preoccupation, conflict, and use for ubiquitous trait; the protective factor was use for learning. Future studies will be required to reveal the additional clinical evidence of the disease entity for smartphone addiction. © 2017 The Korean Academy of Medical Sciences.

To examine the relationship between depression and various components of body composition, including fat and muscle, in elderly Koreans. A cross-sectional sample of a longitudinal cohort from the Ansan Geriatric (AGE) Study. Elderly people living in urban area (Ansan City, South Korea). Eight hundred thirty-six participants (378 male, 458 female) aged 60 and older were recruited from April 2006 to January 2008. Depressive symptoms were examined using the Korean version of the 30-item Geriatric Depression Scale (KGDS). Participants taking antidepressant medications or with a KGDS score of 14 or greater were classified as having depression. Abdominal visceral fat area (VFA) and subcutaneous fat area were assessed using single-slice computed tomography, and appendicular skeletal muscle mass (ASM) and percentage body fat (%BF) were determined using whole-body dual-energy X-ray absorptiometry. Elderly men with depression had a lower ASM than those without depression (P = .01) after adjusting for age, body weight, and height. In men, the risk of depression was lower with higher body mass index (BMI) (odds ratio (OR) per 1-standard deviation (SD) increase = 0.70, 95% confidence interval (CI) = 0.51-0.96) after adjusting for all confounding variables and higher ASM (OR per 1-SD increase = 0.49; 95% CI = 0.29-0.85) after controlling for age, height, and weight. Similarly, depression was negatively associated with BMI in women (OR per 1-SD increase = 0.73; 95% CI = 0.56-0.95). Waist circumference, %BF, and VFA were not consistently associated with depression in men or women. Depression in elderly Koreans is associated with low body mass and sarcopenia, especially in men. © 2011, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

The aim of this study was to compare the prescription patterns according to characteristics of physicians using a survey distributed amongst physicians in Korea. We surveyed the prescription patterns for allergic rhinitis (AR) of the members of the Korean Academy of Asthma, Allergy and Clinical Immunology (KAAACI) and the Korean Association of Otorhinolaryngologists (KAO). Questionnaire contained 4 categories with 28 queries. 448 physicians including 98 internal medicine (IM), 113 pediatrics (PED), and 237 otorhinolaryngology (ENT) were responded. Although the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines are most frequently used in all specialties, seasonal or perennial AR is the most frequent classification system. For the definitive diagnosis of AR, ENT physicians reported using multiple allergen simultaneous test (MAST)/radio allergy sorbent test (RAST) more than others (IM, 10.9%; PED, 20.6%; ENT, 44.2%; P<0.001). In treatment, most physicians reported that antihistamine medication is the initial treatment for AR. PED physicians prescribed fewer intranasal steroid to combinations with an antihistamine than other specialists (IM, 65.3%; PED, 42.5%; ENT, 63.3%), but preferred leukotriene antagonists (IM, 4.1%; PED, 23.0%; ENT, 3.9%; P=0.041). Overall, 53% (235/448) of the physicians performed allergen immunotherapy (AIT), and IM administers the most AIT (IM, 71.6%; PED, 42.0%; ENT, 39.5%; P=0.019). Furthermore, university and general hospital physicians prescribed more AIT than doctors at other hospital types (university hospital, 76.4%; general hospital, 64.3%; local hospital, 21.4%; private clinic, 20.2%; P<0.001). The prescription patterns for AR were different according to the physicians' characteristics and general rate of prescribing AIT is just about 53% in Korea. Thus, the development of complementary Korean-specific guidelines is needed and proper clinical instruction of AIT would be necessary.

Genetic studies require precise phenotype definitions, but electronic medical record (EMR) phenotype data are recorded inconsistently and in a variety of formats. To present lessons learned about validation of EMR-based phenotypes from the Electronic Medical Records and Genomics (eMERGE) studies. The eMERGE network created and validated 13 EMR-derived phenotype algorithms. Network sites are Group Health, Marshfield Clinic, Mayo Clinic, Northwestern University, and Vanderbilt University. By validating EMR-derived phenotypes we learned that: (1) multisite validation improves phenotype algorithm accuracy; (2) targets for validation should be carefully considered and defined; (3) specifying time frames for review of variables eases validation time and improves accuracy; (4) using repeated measures requires defining the relevant time period and specifying the most meaningful value to be studied; (5) patient movement in and out of the health plan (transience) can result in incomplete or fragmented data; (6) the review scope should be defined carefully; (7) particular care is required in combining EMR and research data; (8) medication data can be assessed using claims, medications dispensed, or medications prescribed; (9) algorithm development and validation work best as an iterative process; and (10) validation by content experts or structured chart review can provide accurate results. Despite the diverse structure of the five EMRs of the eMERGE sites, we developed, validated, and successfully deployed 13 electronic phenotype algorithms. Validation is a worthwhile process that not only measures phenotype performance but also strengthens phenotype algorithm definitions and enhances their inter-institutional sharing.

North Korean defectors who settle in South Korea have experienced severe food shortage and transition of food environment which could affect their health status. However, little is known about their anthropometric measurements and dietary intake after settlement in South Korea. The purpose of this study is to compare anthropometric measurements and dietary intake between North Korean young adults who defected to South Korea and those of South Koreans. We hypothesized that North Korean young adults' physiques and dietary intake would be poorer than that of South Koreans. We compared anthropometric measurements and dietary intake from 3-day food records in a cross-sectional study of 103 North Korean young adult defectors, aged 12 to 24 and 309 South Korean subjects. North Korean subjects were significantly shorter (4.9 to 10.8 cm) and lighter (6.0 to 12.5 kg) than the control group. Body mass index were significantly different between North and South Korean groups only in men. North Korean young adult defectors had lower mean daily intakes of energy and most nutrients and food groups compared to the control group, while North Korean subjects had higher nutrient density diet than that of South Koreans. The proportion of subjects who had dietary intakes of nutrients of less than the Estimated Average Requirement was higher in North Korean subjects than in controls except for in the cases of vitamin A and vitamin C. In conclusion, we recommend providing nutrition support programs for North Korean young adult defectors to secure adequate nutrient intake.

Medication reconciliation is a National Patient Safety Goal (NPSG) from The Joint Commission (TJC) that entails reviewing all medications a patient takes after a health care transition. Medication reconciliation is a resource-intensive, error-prone task, and the resources to accomplish it may not be routinely available. Computer-based methods have the potential to overcome these barriers. We designed and explored a rule-based medication reconciliation algorithm to accomplish this task across different healthcare transitions. We tested our algorithm on a random sample of 94 transitions from the Clinical Data Warehouse at the University of Texas Health Science Center at Houston. We found that the algorithm reconciled, on average, 23.4% of the potentially reconcilable medications. Our study did not have sufficient statistical power to establish whether the kind of transition affects reconcilability. We conclude that automated reconciliation is possible and will help accomplish the NPSG.

Korean immigrants rely heavily on their respective churches for assistance with domestic violence. Yet, Korean clergy's responses to domestic violence are unknown. The purpose of this study was to examine factors that influence Korean clergy's responses to domestic violence in their congregations. Results showed that clergy's Korean cultural values, age, and length of residence in the United States influence their responses to domestic violence. Developing a collaborative working relationship between Korean clergy and domestic violence advocates, as well as providing training to Korean clergy targeting their knowledge, beliefs/attitudes, and skills is critical for promoting safety of battered Korean immigrant women. © The Author(s) 2015.

Although electronic health records (EHRs) have the potential to provide a foundation for quality and safety algorithms, few studies have measured their impact on automated adverse event (AE) and medical error (ME) detection within the neonatal intensive care unit (NICU) environment. This paper presents two phenotyping AE and ME detection algorithms (ie, IV infiltrations, narcotic medication oversedation and dosing errors) and describes manual annotation of airway management and medication/fluid AEs from NICU EHRs. From 753 NICU patient EHRs from 2011, we developed two automatic AE/ME detection algorithms, and manually annotated 11 classes of AEs in 3263 clinical notes. Performance of the automatic AE/ME detection algorithms was compared to trigger tool and voluntary incident reporting results. AEs in clinical notes were double annotated and consensus achieved under neonatologist supervision. Sensitivity, positive predictive value (PPV), and specificity are reported. Twelve severe IV infiltrates were detected. The algorithm identified one more infiltrate than the trigger tool and eight more than incident reporting. One narcotic oversedation was detected demonstrating 100% agreement with the trigger tool. Additionally, 17 narcotic medication MEs were detected, an increase of 16 cases over voluntary incident reporting. Automated AE/ME detection algorithms provide higher sensitivity and PPV than currently used trigger tools or voluntary incident-reporting systems, including identification of potential dosing and frequency errors that current methods are unequipped to detect.

2016-01-01

Background Regarding the importance of right diagnosis in medical applications, various methods have been exploited for processing medical images solar. The method of segmentation is used to analyze anal to miscall structures in medical imaging. Objective This study describes a new method for brain Magnetic Resonance Image (MRI) segmentation via a novel algorithm based on genetic and regional growth. Methods Among medical imaging methods, brains MRI segmentation is important due to high contrast of non-intrusive soft tissue and high spatial resolution. Size variations of brain tissues are often accompanied by various diseases such as Alzheimer’s disease. As our knowledge about the relation between various brain diseases and deviation of brain anatomy increases, MRI segmentation is exploited as the first step in early diagnosis. In this paper, regional growth method and auto-mate selection of initial points by genetic algorithm is used to introduce a new method for MRI segmentation. Primary pixels and similarity criterion are automatically by genetic algorithms to maximize the accuracy and validity in image segmentation. Results By using genetic algorithms and defining the fixed function of image segmentation, the initial points for the algorithm were found. The proposed algorithms are applied to the images and results are manually selected by regional growth in which the initial points were compared. The results showed that the proposed algorithm could reduce segmentation error effectively. Conclusion The study concluded that the proposed algorithm could reduce segmentation error effectively and help us to diagnose brain diseases. PMID:27672629

The Texas Medication Algorithm Project (TMAP) has been a public-academic collaboration in which guidelines for medication treatment of schizophrenia, bipolar disorder, and major depressive disorder were used in selected public outpatient clinics in Texas. Subsequently, these algorithms were implemented throughout Texas and are being used in other states. Guidelines require updating when significant new evidence emerges; the antipsychotic algorithm for schizophrenia was last updated in 1999. This article reports the recommendations developed in 2002 and 2003 by a group of experts, clinicians, and administrators. A conference in January 2002 began the update process. Before the conference, experts in the pharmacologic treatment of schizophrenia, clinicians, and administrators reviewed literature topics and prepared presentations. Topics included ziprasidone's inclusion in the algorithm, the number of antipsychotics tried before clozapine, and the role of first generation antipsychotics. Data were rated according to Agency for Healthcare Research and Quality criteria. After discussing the presentations, conference attendees arrived at consensus recommendations. Consideration of aripiprazole's inclusion was subsequently handled by electronic communications. The antipsychotic algorithm for schizophrenia was updated to include ziprasidone and aripiprazole among the first-line agents. Relative to the prior algorithm, the number of stages before clozapine was reduced. First generation antipsychotics were included but not as first-line choices. For patients refusing or not responding to clozapine and clozapine augmentation, preference was given to trying monotherapy with another antipsychotic before resorting to antipsychotic combinations. Consensus on algorithm revisions was achieved, but only further well-controlled research will answer many key questions about sequence and type of medication treatments of schizophrenia.

Little is known about using electronic medical records to identify patients with chronic obstructive pulmonary disease to improve quality of care. Our objective was to develop electronic medical record algorithms that can accurately identify patients with obstructive pulmonary disease. A retrospective chart abstraction study was conducted on data from the Electronic Medical Record Administrative data Linked Database (EMRALD ® ) housed at the Institute for Clinical Evaluative Sciences. Abstracted charts provided the reference standard based on available physician-diagnoses, chronic obstructive pulmonary disease-specific medications, smoking history and pulmonary function testing. Chronic obstructive pulmonary disease electronic medical record algorithms using combinations of terminology in the cumulative patient profile (CPP; problem list/past medical history), physician billing codes (chronic bronchitis/emphysema/other chronic obstructive pulmonary disease), and prescriptions, were tested against the reference standard. Sensitivity, specificity, and positive/negative predictive values (PPV/NPV) were calculated. There were 364 patients with chronic obstructive pulmonary disease identified in a 5889 randomly sampled cohort aged ≥ 35 years (prevalence = 6.2%). The electronic medical record algorithm consisting of ≥ 3 physician billing codes for chronic obstructive pulmonary disease per year; documentation in the CPP; tiotropium prescription; or ipratropium (or its formulations) prescription and a chronic obstructive pulmonary disease billing code had sensitivity of 76.9% (95% CI:72.2-81.2), specificity of 99.7% (99.5-99.8), PPV of 93.6% (90.3-96.1), and NPV of 98.5% (98.1-98.8). Electronic medical record algorithms can accurately identify patients with chronic obstructive pulmonary disease in primary care records. They can be used to enable further studies in practice patterns and chronic obstructive pulmonary disease management in primary care. NOVEL ALGORITHM SEARCH TECHNIQUE: Researchers develop an algorithm that can accurately search through electronic health records to find patients with chronic lung disease. Mining population-wide data for information on patients diagnosed and treated with chronic obstructive pulmonary disease (COPD) in primary care could help inform future healthcare and spending practices. Theresa Lee at the University of Toronto, Canada, and colleagues used an algorithm to search electronic medical records and identify patients with COPD from doctors' notes, prescriptions and symptom histories. They carefully adjusted the algorithm to improve sensitivity and predictive value by adding details such as specific medications, physician codes related to COPD, and different combinations of terminology in doctors' notes. The team accurately identified 364 patients with COPD in a randomly-selected cohort of 5889 people. Their results suggest opportunities for broader, informative studies of COPD in wider populations.

The year 2012 was the 50th anniversary of the Korean Neurosurgical Society, and in 2013, the 15th World Congress of Neurosurgery took place in Seoul, Korea. Thus, it is an appropriate occasion to introduce the world to the history of the Korean Neurosurgical Society and the foundation, development, and growth of Korean neurosurgery. Historical materials and pictures were collected and reviewed from the history book and photo albums of the Korean Neurosurgical Society. During the last 50 years, the Korean Neurosurgical Society and Korean neurosurgery have developed and grown enormously not only in quantity but also in quality. In every aspect, the turning point from the old to the new era of the Korean Neurosurgical Society and Korean neurosurgery was the year 1980. Copyright © 2015. Published by Elsevier Inc.

In the second report in our series on the historical investigation on the introduction of western psychiatry into Korea, authors deal with the status of psychiatric education during the Japanese forced annexation of Korea. The first lecture on psychiatry in Korea under the title "Mental Diseases" was held in Dae-han-eui-won around 1910. In 1913, the Department of Psychiatry branched off from the Department of Internal Medicine of Chosen-sotoku-fu-iing, the Colonial Governmental Clinic, the successor of Dae-han-eui-won. The chairman, Professor Suiju Sinji; and the Korean assistant Sim Ho-seop administered the psychiatric ward with 35 beds. Since 1913, an Australian missionary psychiatrist, Dr. McLaren began to teach neurology and psychiatry at Severance Union Medical College and established a Department of Psychiatry in 1923. Dr. McLaren was a faithful Christian and open minded toward Oriental religious thought such as in Buddhism and Taoism. He devoted himself to the humanitarian care of mentally ill patients and served there until 1937 when he had to leave the land due to Japanese persecution. His disciple, Dr. Lee Jung Cheol succeeded the chair of the Psychiatric Department of Severance Medical College and served until 1939. In 1916, Keijo (Seoul) Medical College was established and in 1928, Keijo Teikoku Daigaku (Imperial University). From 1929 to 1941, the Department of Neurology and Psychiatry of Keijo Imperial University grew under the chairmanship of Professor Kubo Kioji followed by Professor Watanabe until 1945. Many assistants including a few Koreans were gathered to the Department for training and research. The main textbook used for the psychiatric education for medical students in Korea was on Kraepelinian German Psychiatry translated and edited by Japanese psychiatrists. Lectures and clerkships for Neurology and Psychiatry were allocated generally in the curriculum for senior students for weekly 1-3 hours. Postgraduate professional training for the psychiatrists was carried out according to the tutorial system under the supervision of professors and staff. In regard to a wide range of references discovered in the library of the Department of Neurology and Psychiatry, Keijo Imperial University the trainees seem to have had opportunity to contact with diverse subspecialties of psychiatry and also to exercise specific laboratory examinations in the setting of the German linik". Comparisons of psychiatry in Korea and Japan during Japanese occupation suggest the following conclusions: 1. Extreme discrimination against Korean trainees in their academic careersprobably due to colonial policy. After 35 years of Japanese occupation of Korea only ten Korean neuro-psychiatrists and neurologists were left; 2. Somewhat narrow academic interests of psychiatrists in Korea in research fields focusing on neuropathology and opium addiction etc and the lackness of the interest in social psychiatric issues: for example, the rights of the mentally ill patient or non-restraining care systems as seen in Japanese psychiatry in Japan. 3. Extremely limited number of psychiatry teaching staffs in Korea. For a long time Keijo Imperial University's Department of Neurology and Psychiatry was the only center for training psychiatrists in Korea.

This research is motivated by the issue of classifying illnesses of chronically ill patients for decision support in clinical settings. Our main objective is to propose multi-label classification of multivariate time series contained in medical records of chronically ill patients, by means of quantization methods, such as bag of words (BoW), and multi-label classification algorithms. Our second objective is to compare supervised dimensionality reduction techniques to state-of-the-art multi-label classification algorithms. The hypothesis is that kernel methods and locality preserving projections make such algorithms good candidates to study multi-label medical time series. We combine BoW and supervised dimensionality reduction algorithms to perform multi-label classification on health records of chronically ill patients. The considered algorithms are compared with state-of-the-art multi-label classifiers in two real world datasets. Portavita dataset contains 525 diabetes type 2 (DT2) patients, with co-morbidities of DT2 such as hypertension, dyslipidemia, and microvascular or macrovascular issues. MIMIC II dataset contains 2635 patients affected by thyroid disease, diabetes mellitus, lipoid metabolism disease, fluid electrolyte disease, hypertensive disease, thrombosis, hypotension, chronic obstructive pulmonary disease (COPD), liver disease and kidney disease. The algorithms are evaluated using multi-label evaluation metrics such as hamming loss, one error, coverage, ranking loss, and average precision. Non-linear dimensionality reduction approaches behave well on medical time series quantized using the BoW algorithm, with results comparable to state-of-the-art multi-label classification algorithms. Chaining the projected features has a positive impact on the performance of the algorithm with respect to pure binary relevance approaches. The evaluation highlights the feasibility of representing medical health records using the BoW for multi-label classification tasks. The study also highlights that dimensionality reduction algorithms based on kernel methods, locality preserving projections or both are good candidates to deal with multi-label classification tasks in medical time series with many missing values and high label density.

2008-12-01

In order to fill the discrepancy between the necessity of providing prompt and proper treatment to dental trauma patients, and the inadequate knowledge among medics and corpsmen, as well as the lack of instructions in first-aid textbook and manuals, and after reviewing the dental literature, a simple algorithm for non-professional first-aid management for various injuries to hard (teeth) and soft oral tissues, is presented. The recommended management of tooth avulsion, subluxation and luxation, crown fracture and lip, tongue or gingival laceration included in the algorithm. Along with a list of after-hour dental clinics, this symptoms- and clinical-appearance-based algorithm is suited to tuck easily into a pocket for quick utilization by medics/corpsmen in an emergency situation. Although the algorithm was developed for the usage of military non-dental health-care providers, this method could be adjusted and employed in the civilian environment as well.

Due to a significant decline in the costs associated with next-generation sequencing, it has become possible to decipher the genetic architecture of a population by sequencing a large number of individuals to a deep coverage. The Korean Personal Genomes Project (KPGP) recently sequenced 35 Korean genomes at high coverage using the Illumina Hiseq platform and made the deep sequencing data publicly available, providing the scientific community opportunities to decipher the genetic architecture of the Korean population. In this study, we used two single nucleotide variant (SNV) calling pipelines: mapping the raw reads obtained from whole genome sequencing of 35 Korean individuals in KPGP using BWA and SOAP2 followed by SNV calling using SAMtools and SOAPsnp, respectively. The consensus SNVs obtained from the two SNV pipelines were used to represent the SNVs of the Korean population. We compared these SNVs to those from 17 other populations provided by the HapMap consortium and the 1000 Genomes Project (1KGP) and identified SNVs that were only present in the Korean population. We studied the mutation spectrum and analyzed the genes of non-synonymous SNVs only detected in the Korean population. We detected a total of 8,555,726 SNVs in the 35 Korean individuals and identified 1,213,613 SNVs detected in at least one Korean individual (SNV-1) and 12,640 in all of 35 Korean individuals (SNV-35) but not in 17 other populations. In contrast with the SNVs common to other populations in HapMap and 1KGP, the Korean only SNVs had high percentages of non-silent variants, emphasizing the unique roles of these Korean only SNVs in the Korean population. Specifically, we identified 8,361 non-synonymous Korean only SNVs, of which 58 SNVs existed in all 35 Korean individuals. The 5,754 genes of non-synonymous Korean only SNVs were highly enriched in some metabolic pathways. We found adhesion is the top disease term associated with SNV-1 and Nelson syndrome is the only disease term associated with SNV-35. We found that a significant number of Korean only SNVs are in genes that are associated with the drug term of adenosine. We identified the SNVs that were found in the Korean population but not seen in other populations, and explored the corresponding genes and pathways as well as the associated disease terms and drug terms. The results expand our knowledge of the genetic architecture of the Korean population, which will benefit the implementation of personalized medicine for the Korean population.

Medical image registration by combining global and local information: a chain-type diffeomorphic demons algorithm.

2013-12-07

The demons algorithm is a popular algorithm for non-rigid image registration because of its computational efficiency and simple implementation. The deformation forces of the classic demons algorithm were derived from image gradients by considering the deformation to decrease the intensity dissimilarity between images. However, the methods using the difference of image intensity for medical image registration are easily affected by image artifacts, such as image noise, non-uniform imaging and partial volume effects. The gradient magnitude image is constructed from the local information of an image, so the difference in a gradient magnitude image can be regarded as more reliable and robust for these artifacts. Then, registering medical images by considering the differences in both image intensity and gradient magnitude is a straightforward selection. In this paper, based on a diffeomorphic demons algorithm, we propose a chain-type diffeomorphic demons algorithm by combining the differences in both image intensity and gradient magnitude for medical image registration. Previous work had shown that the classic demons algorithm can be considered as an approximation of a second order gradient descent on the sum of the squared intensity differences. By optimizing the new dissimilarity criteria, we also present a set of new demons forces which were derived from the gradients of the image and gradient magnitude image. We show that, in controlled experiments, this advantage is confirmed, and yields a fast convergence.

A Parallel Nonrigid Registration Algorithm Based on B-Spline for Medical Images

Wang, Yangping; Wang, Song

2016-01-01

The nonrigid registration algorithm based on B-spline Free-Form Deformation (FFD) plays a key role and is widely applied in medical image processing due to the good flexibility and robustness. However, it requires a tremendous amount of computing time to obtain more accurate registration results especially for a large amount of medical image data. To address the issue, a parallel nonrigid registration algorithm based on B-spline is proposed in this paper. First, the Logarithm Squared Difference (LSD) is considered as the similarity metric in the B-spline registration algorithm to improve registration precision. After that, we create a parallel computing strategy and lookup tables (LUTs) to reduce the complexity of the B-spline registration algorithm. As a result, the computing time of three time-consuming steps including B-splines interpolation, LSD computation, and the analytic gradient computation of LSD, is efficiently reduced, for the B-spline registration algorithm employs the Nonlinear Conjugate Gradient (NCG) optimization method. Experimental results of registration quality and execution efficiency on the large amount of medical images show that our algorithm achieves a better registration accuracy in terms of the differences between the best deformation fields and ground truth and a speedup of 17 times over the single-threaded CPU implementation due to the powerful parallel computing ability of Graphics Processing Unit (GPU).

Objective To examine the effects of varying diagnostic and pharmaceutical criteria on the performance of claims-based algorithms for identifying beneficiaries with hypertension, heart failure, chronic lung disease, arthritis, glaucoma, and diabetes. Study Setting Secondary 1999–2000 data from two Medicare+Choice health plans. Study Design Retrospective analysis of algorithm specificity and sensitivity. Data Collection Physician, facility, and pharmacy claims data were extracted from electronic records for a sample of 3,633 continuously enrolled beneficiaries who responded to an independent survey that included questions about chronic diseases. Principal Findings Compared to an algorithm that required a single medical claim in a one-year period that listed the diagnosis, either requiring that the diagnosis be listed on two separate claims or that the diagnosis to be listed on one claim for a face-to-face encounter with a health care provider significantly increased specificity for the conditions studied by 0.03 to 0.11. Specificity of algorithms was significantly improved by 0.03 to 0.17 when both a medical claim with a diagnosis and a pharmacy claim for a medication commonly used to treat the condition were required. Sensitivity improved significantly by 0.01 to 0.20 when the algorithm relied on a medical claim with a diagnosis or a pharmacy claim, and by 0.05 to 0.17 when two years rather than one year of claims data were analyzed. Algorithms that had specificity more than 0.95 were found for all six conditions. Sensitivity above 0.90 was not achieved all conditions. Conclusions Varying claims criteria improved the performance of case-finding algorithms for six chronic conditions. Highly specific, and sometimes sensitive, algorithms for identifying members of health plans with several chronic conditions can be developed using claims data. PMID:15533190

North Korean adolescent defectors experience adaptation difficulties along with a wide range of psychosocial problems, but no study has yet examined their Internet addiction symptoms. We compared early traumatic experiences, self-esteem, negative cognition, and Internet addiction symptoms, as well as the relationships between these variables, between North Korean adolescent defectors and South Korean adolescents. Fifty-six North Korean adolescent defectors and 112 age- and sex- matched South Korean adolescents participated. The analyses examined the relationship between traumatic experiences and Internet addiction symptoms, with negative automatic thoughts or low self-esteem as mediators of these relations. North Korean adolescent defectors tended to have higher levels of negative automatic thoughts and more severe Internet addiction symptoms, as well as better self-esteem, than did South Korean adolescents. Furthermore, only among North Korean adolescent defectors, traumatic experiences were positively associated with Internet addition symptoms via increasing negative automatic thoughts. North Korean adolescent defectors are more susceptible to Internet addiction, negative cognitions, and early traumatic experiences compared to South Korean adolescents. However, the cross-sectional design of this study precludes consideration of the causality of these relationships. Interventions aiming to correct negative cognitions and increase self-esteem may be helpful for North Korean adolescent defectors with problematic Internet use. Copyright © 2017 Elsevier B.V.

Medical Faculties Network (MEFANET) has established itself as the authority for setting standards for medical educators in the Czech Republic and Slovakia, 2 independent countries with similar languages that once comprised a federation and that still retain the same curricular structure for medical education. One of the basic goals of the network is to advance medical teaching and learning with the use of modern information and communication technologies. We present the education portal AKUTNE.CZ as an important part of the MEFANET's content. Our focus is primarily on simulation-based tools for teaching and learning acute medicine issues. Three fundamental elements of the MEFANET e-publishing system are described: (1) medical disciplines linker, (2) authentication/authorization framework, and (3) multidimensional quality assessment. A new set of tools for technology-enhanced learning have been introduced recently: Sandbox (works in progress), WikiLectures (collaborative content authoring), Moodle-MEFANET (central learning management system), and Serious Games (virtual casuistics and interactive algorithms). The latest development in MEFANET is designed for indexing metadata about simulation-based learning objects, also known as electronic virtual patients or virtual clinical cases. The simulations assume the form of interactive algorithms for teaching and learning acute medicine. An anonymous questionnaire of 10 items was used to explore students' attitudes and interests in using the interactive algorithms as part of their medical or health care studies. Data collection was conducted over 10 days in February 2013. In total, 25 interactive algorithms in the Czech and English languages have been developed and published on the AKUTNE.CZ education portal to allow the users to test and improve their knowledge and skills in the field of acute medicine. In the feedback survey, 62 participants completed the online questionnaire (13.5%) from the total 460 addressed. Positive attitudes toward the interactive algorithms outnumbered negative trends. The peer-reviewed algorithms were used for conducting problem-based learning sessions in general medicine (first aid, anesthesiology and pain management, emergency medicine) and in nursing (emergency medicine for midwives, obstetric analgesia, and anesthesia for midwifes). The feedback from the survey suggests that the students found the interactive algorithms as effective learning tools, facilitating enhanced knowledge in the field of acute medicine. The interactive algorithms, as a software platform, are open to academic use worldwide. The existing algorithms, in the form of simulation-based learning objects, can be incorporated into any educational website (subject to the approval of the authors).

Introduction: This study, informed by ecological frameworks, compared the prevalence, predictors, and association of home smoking restrictions with secondhand smoke exposure (SHSe) between Koreans in Seoul, South Korea, and Korean Americans in California, United States. Methods: A cross-sectional survey was drawn from telephone interviews with Korean adults in Seoul (N = 500) and California (N = 2,830) during 2001–02. Multivariable regressions were used for analyses. Results: Koreans, compared with Korean Americans, had significantly fewer complete home smoking bans, 19% (95% CI: 16–23) versus 66% (95% CI: 64–68), and were more likely to not have a home smoking restriction, 64% (95% CI: 60–69) versus 5% (95% CI: 4–6). Home smoking restrictions were associated with lower home SHSe; however, the impact was consistently larger among Korean Americans. Households with more SHSe sources were less likely to have the strongest home smoking restrictions, where the difference in complete bans among Korean Americans versus Koreans was largely among those at low risk of SHSe, 82% (95% CI: 76–86) versus 36% (95% CI: 17–57), while high-risk Korean American and Koreans had similar low probabilities, 10% (95% CI: 7–13) versus 7% (95% CI: 3–13). Conclusions: Consistent with ecological frameworks, exposure to California’s antismoking policy and culture was associated with stronger home smoking restrictions and improved effectiveness. Interventions tailored to Korean and Korean American SHSe profiles are needed. Behavioral interventions specifically for high-risk Korean Americans and stronger policy controls for Koreans may be effective at rapidly expanding home smoking restrictions. PMID:20924042

[From influence to confluence : positioning the history of pre-modern Korean medicine in East Asia].

PubMed

Suh, Soyoung

2010-12-31

This article surveys studies focusing on pre-modern Korean medicine, which are both written in English and analyzed primary sources up to 1876. Overall, the history of pre-modern Korean medicine is an unknown filed in Anglophone academia. Yung Sik Kim's, James Palais's, and Carter Ecart's problematization of the nationalist framework of Korean scholarship partially explains the marginality of the field. Addressing these criticisms, this review argues that pre-modern Korean medicine's uneasy task lies in both elaborating Korea's own experience of medicine, while simultaneously avoiding making the "Korean" category itself essential. Korean narratives of premodern medicine need to go beyond the mere territorilalization of Korean medicine against its Chinese, Japanese, or Western counterparts, thereby to tackle the field's own boundary of research objects. The existing scholarship in English responds to this challenge by primarily examining the way in which Korea has shared textual tradition with China. Sirhak scholars' innovation in medicine, visual representation of Tongŭi bogam, Korean management of epidemics in the eleventh century, and Korean indexing of local botanicals, engages not only native achievements, but also the process of modifying medicine across geographical and political boundaries. More to the point, the emerging native narratives, although written in Korean, are implicitly resonant with those currently present in Anglophone academia. Taking "tension," "intertextuality," and "local traits" as a lens, this article assesses a series of current research in Korea. Aiming to go beyond appeals for a "distinctively" Korean experience of medicine, the future study of Korean pre-modern medicine will further elucidate confluences of different flows, such as "Chinese and Korean," "universal and local," "center and periphery," and "native and foreign," which will eventually articulate a range of Korean techniques of creating a bricolage in medicine.

The social identity of another person, in addition to the social identity of self, can be an important factor affecting the types of attribution judgments and emotions that individuals indicate for the other person. In April 2007, the perpetrator of the shooting incident on the Virginia Tech University campus was identified as a person who emigrated to the USA from Korea at a young age. The current study compared non-Korean Americans, Korean Americans, Koreans in the USA, and Koreans in Korea in terms of their attributions and emotions concerning the perpetrator and the shooting incident. Participants were asked to indicate (1) the extent to which they attributed the cause of the incident to either American society or the perpetrator, (2) their emotions (e.g., upset), and (3) the extent to which they categorized the perpetrator as an American, a Korean American, or a Korean. The results indicated that non-Korean Americans were most likely to attribute the cause of the incident to the perpetrator as opposed to American society. Non-Korean Americans, Korean Americans, and Koreans in the United States had more negative emotions (e.g., unhappy, sad, and upset) about the incident than Koreans in Korea did. The results also indicated that individuals differed in their attributions and emotions depending on how they categorized the perpetrator. For example, categorizing the perpetrator as being a Korean was positively related to Americans' tendency to hold the perpetrator responsible, while categorizing the perpetrator as being an American was negatively related to the tendency to hold the perpetrator responsible among Koreans in Korea. The findings may imply that social identity theory, intergroup emotion theory, and cultural orientations (e.g., individualism and collectivism) can provide insights into people's reactions to a tragic incident.

Background The number of North Korean refugees entering South Korea is rising. Few studies have investigated the risk of non-communicable disease in North Korean refugees. Moreover, kidney insufficiency, a risk factor for cardiovascular disease, has not been studied in this population. We compared the prevalence of non-communicable disease and kidney function in North Korean refugees and South Koreans. Methods Our study was conducted using a case-control design. We enrolled 118 North Korean refugees from the Hana Center and selected 472 randomly sampled South Korean individuals as controls, who were age- and sex-matched with the North Korean refugees in a ratio of 1:4, from the 2014 Korea National Health and Nutrition Examination Survey database. Results The prevalence of non-communicable disease did not differ significantly between the groups; however, a low estimated glomerular filtration rate (eGFR; <90 mL/min per 1.73 m2) was more prevalent in the North Korean refugees than in the South Korean population (52.1% vs. 29.9%, P<0.001). After adjusting for covariates and weight gain after escape, the prevalence of a low eGFR was associated with the length of residence in South Korea (odds ratio, 2.84; 95% confidence interval, 1.02–7.89). Conclusion The prevalence of non-communicable disease did not differ between North Korean refugees and the South Korean population, while a low eGFR was more prevalent in North Korean refugees than in South Koreans. Moreover, after adjusting for other covariates, the prevalence of a low eGFR in North Korean refugees was associated with the length of residence in South Korea. PMID:29788704

To evaluate oral anticoagulant (OAC) utilization in patients with atrial fibrillation after the changes in the health insurance coverage policy in July 2015. We used the Health Insurance Review and Assessment Service-National Patient Samples (HIRA-NPS) between 2014 and 2016. The HIRA-NPS, including approximately 1.4 million individuals, is a stratified random sample of 3% of the entire Korean population using 16 age groups and 2 sex groups. The HIRA-NPS comprises personal and medical information such as surgical or medical treatment provided, diagnoses, age, sex, region of medical institution, and clinician characteristics. The studied drugs included non-vitamin K antagonist OACs (NOACs) such as apixaban, dabigatran, edoxaban, and rivaroxaban, and were compared with warfarin. We analyzed drug utilization pattern under three aspects: person, time, and place. The number of patients with atrial fibrillation who were prescribed OACs was 3,114, 3,954, and 4,828; and the proportions of prescribed NOACs to total OACs were 5.1%, 36.2%, and 60.8% in 2014, 2015, and 2016, respectively. The growth rate of OACs prescription increased from 61.4 patients/quarter before June 2015 to 147.7 patients/quarter thereafter. These changes were predominantly in elderly individuals aged more than 70 years. The proportion of NOACs to OACs showed significant regional difference. The change of health insurance coverage policy substantially influenced OACs prescription pattern in whole Korean region. But the impact has been significantly different among regions and age groups, which provides the evidence for developing standard clinical practice guideline on OACs use.

The purpose of this study was to investigate the clinical, laboratory, and pathologic characteristics of dense deposit disease (DDD) in Korean children and to determine whether these characteristics differ between Korean and American children with DDD. In 2010, we sent a structured protocol about DDD to pediatric nephrologists throughout Korea. The data collected were compared with previously published data on 14 American children with DDD. Korean children had lower 24-hr urine protein excretion and higher serum albumin levels than American children. The light microscopic findings revealed that a higher percentage of Korean children had membranoproliferative glomerulonephritis patterns (Korean, 77.8%; American, 28.6%, P = 0.036), whereas a higher percentage of American children had crescents (Korean, 0%; American, 78.6%, P < 0.001). The findings from the electron microscopy revealed that Korean children were more likely to have segmental electron dense deposits in the lamina densa of the glomerular basement membrane (Korean, 100%; American, 28.6%, P = 0.002); mesangial deposit was more frequent in American children (Korean, 66.7%; American, 100%, P = 0.047). The histological findings revealed that Korean children with DDD were more likely to show membranoproliferative glomerulonephritis patterns than American children. The degree of proteinuria and hypoalbuminemia was milder in Korean children than American children. PMID:23091320

In digital virtual human project, image data acquires from the freezing slice of human body specimen. The color and brightness between a group of images of a certain organ could be quite different. The quality of these images could bring great difficulty in edge extraction, segmentation, as well as 3D reconstruction process. Thus it is necessary to unify the color of the images. The color transfer algorithm is a good algorithm to deal with this kind of problem. This paper introduces the principle of this algorithm and uses it in the medical image processing.

Private health insurance in South Korea mainly functions as supplementary and complementary health insurance that compensates for insufficient coverage by National Health Insurance. However, full private coverage of public sector cost-sharing led to the problem of encouraging moral hazard-induced utilization, resulting in a policy change that occurred in October 2009. At that time, the Korean government introduced a minimum cost-sharing policy for indemnity health insurance. The purpose of this study was to analyze the effect of cost-sharing in private health insurance on health care utilization. We analyzed data collected from the Korean Health Panel Survey from October 2008 to December 2011. We restricted the two groups to 803 purchasers with indemnity health insurance and 7023 non-purchasers who did not obtain any private health insurance. A difference-in-difference analysis was used to evaluate the effect of the 2009 policy. After the policy change, the utilization of outpatient visits by purchasers gradually decreased more than non-purchasers (0.015 in 2009 [p = 0.758], -0.117 in 2010 [p < 0.016], and -0.140 in 2011 [p = 0.004]). However, utilization of inpatient services was not statistically significant. Notably, the magnitude of the cost-sharing effect in indemnity health insurance was stronger for those receiving medical aid. Among this group, utilization of outpatient services (after the policy change in 2009) decreased more so than non-purchasers. Patients with three or more chronic diseases have not changed their health care utilization. Our results implied meaningful lessons for decision-makers and future health insurance policies in Korea and other countries in terms of cost-sharing in medical care. When policy makers intend to implement the cost-sharing, a different copayment scheme is needed according to the socioeconomic status or disease severity.

The experiences of health services research and health services research training in Korea.

Moon, O R

Early in the 1970s the Korean government recognized the necessity of Health Services Research (HSR). The law of the Korea Health Development Institute was promulgated in 1975, and a contribution from the Republic was combined with an Agency for International Development loan to field test low-cost health service strategies. A program to deploy Community Health Practitioners (CHPs), similar to family nurse practitioners or Medex has been demonstrated to be effective. The CHP training program grew from 9 in 1980 to 1343 in 1984. CHP's main functions are curative, preventive, educative, and administrative. They are selected registered nurses and/or midwives, where possible from serviced communities. They are trained in 24 weeks, including 12 weeks of clinical practice, in an anticipated recruiting post. CHPs help train village health volunteers (VHVs), who are literate women chosen by their communities. They work closely with the CHPs as a liaison with the village and in information gathering. An HSR orientation workshop held in Chuncheon in 1980, discussed role, policy, status, finance components, information systems, behavioral and manpower components, staff training, protocols for project development, HSR in the future and evaluation of the conference. In 1980, a National Workshop on Biomedical Research Methodology was also held, with World Health Organization and Korean consultants. Training of junior scientists would include introduction to scientific method, statement of problems, quantitative study technics, research proposals, and interpretation of results. The Korean Institute of Public Health sponsored a 1982 experts forum on the health care system, medical facilities, organizational management, financing and medical security, and health behavioral aspects. Training of trainers and lower level field workers, orientation of program managers, researchers, and communities themselves should all be training priorities. In future, CHPs should be refresher-trained in prevention-oriented care, and physicians educated in the benefits of CHP input as a complementary rather than competitive service.

This study examined the healthcare experiences of Korean immigrants aged 40-64 living in the North Carolina Triangle area of the Southeastern United States. Using a mixed methods design, we collected quantitative data via a questionnaire from 125 participants and conducted a focus group with 10 interviewees from December 2010 to February 2011. The quantitative data were analysed using t-tests and chi-square tests, and a thematic analysis was used for the focus group study. Questionnaire findings showed that only 27.2% had sufficient English skills to communicate adequately. Participants with insurance were significantly more likely to be employed (P < 0.001), had higher incomes (P = 0.011) and higher education (P < 0.001), and had greater English-speaking ability (P = 0.011) than those without insurance. Participants who did not use healthcare services showed significantly less knowledge (P < 0.001) of and less satisfaction (P = 0.034) with the healthcare system than those using healthcare services. Sixty-two participants (49.6%) reported having no health insurance for one or more of the following reasons: high costs (75.8%), medical tourism (22.6%) and lack of information or knowledge (6.5%). The following themes emerged from the data collected during the focus group: (i) barriers to utilisation of healthcare services; (ii) facilitators of utilisation of healthcare services; and (iii) social support seeking for health management. Our mixed methods study findings indicate that healthcare disparities exist among Korean immigrants and that a number of factors, including health literacy, may contribute to their poor health outcomes. Continued collaboration among community members, healthcare professionals and academicians is needed to discuss the community's health concerns and to develop sustainable programmes that will ensure meaningful access to care for those with limited English proficiency and medically underserved populations. © 2014 John Wiley & Sons Ltd.

This study compared the ethnic identity and well-being of Korean Americans who were adopted internationally with immigrant/U.S.-born Korean Americans and Korean international students, as well as the relationship between ethnic identity and well-being for each group. One-hundred and seven college students completed measures of ethnic identity and subjective well-being. Immigrant/U.S.-born Korean Americans had higher ethnic identity scores than the other two groups. Immigrant/U.S.-born Korean Americans also had higher positive affect scores than international students. Ethnic identity was positively correlated with positive affect for all three groups (r’s = .27 – .34), but was negatively correlated with negative affect for international students (r = −.44). Overall, the results suggest that ethnic identity, although slightly lower than non-adopted peers, is relevant to the well-being of adopted Korean American college students. PMID:20694190

Purpose This study investigates Korean speech sound development, including articulatory error patterns, among the Japanese-Korean children whose mothers are Japanese immigrants to Korea. Methods The subjects were 28 Japanese-Korean children with normal development born to Japanese women immigrants who lived in Jeonbuk province, Korea. They were assessed through Computerized Speech Lab 4500. The control group consisted of 15 Korean children who lived in the same area. Results The values of the voice onset time of consonants /ph/, /t/, /th/, and /k*/ among the children were prolonged. The children replaced the lenis sounds with aspirated or fortis sounds rather than replacing the fortis sounds with lenis or aspirated sounds, which are typical among Japanese immigrants. The children showed numerous articulatory errors for /c/ and /l/ sounds (similar to Koreans) rather than errors on /p/ sounds, which are more frequent among Japanese immigrants. The vowel formants of the children showed a significantly prolonged vowel /o/ as compared to that of Korean children (P<0.05). The Japanese immigrants and their children showed a similar substitution /n/ for /ɧ/ [Japanese immigrants (62.5%) vs Japanese-Korean children (14.3%)], which is rarely seen among Koreans. Conclusion The findings suggest that Korean speech sound development among Japanese-Korean children is influenced not only by the Korean language environment but also by their maternal language. Therefore, appropriate language education programs may be warranted not only or immigrant women but also for their children. PMID:21189968

In Korea, the treatment of hypertension and dyslipidemia constitutes an important strategy for the prevention of cardiovascular disease (CVD). This study sought to investigate the cost-effectiveness (from the Korean health care system perspective) of prescribing a proprietary formulation single-tablet fixed-dose combination of amlodipine and atorvastatin (at weighted mean doses of 5 mg and 10.25 mg, respectively) to all eligible patients aged > or = 45 years for the primary prevention of CVD (ie, coronary heart disease and ischemic stroke) in Korea, compared with currently observed patterns of blood-pressure and lipid-lowering medication prescription and use. A Markov model was developed with 4 health states: alive without CVD, alive with CVD, dead from CVD, and dead from non-CVD causes. The model population comprised 244 Koreans aged >/=45 years from the 2005 Korean National Health and Nutrition Examination Survey (KNHNES) without a history of myocardial infarction (MI) or stroke who met current criteria for both blood-pressure and lipid-lowering treatment. From a 2008 baseline, follow-up was simulated for 40 years. Cardiovascular risk was estimated for each subject individually using a multivariate, Asian population-specific equation, and updated with ongoing cycles. Decision analysis compared the effects of prescribing the fixed-dose combination to all subjects versus currently observed patterns of treatment. Data regarding the blood-pressure and lipid-lowering efficacies of combination therapy were drawn from the Respond trial. Costs of the fixed-dose combination tablet and CVD were sourced from pharmaceutical pricing lists and Korean Health Insurance Review and Assessment Services estimates, respectively. Utility values for CVD were obtained from a large Korean utility study. In the model, of the 244 treatment-eligible subjects, 126 (51.6%) and 13 (5.3%) were taking blood-pressure and lipid-lowering therapy, respectively. Use of single-tablet fixed-dose combination amlodipine and atorvastatin by all subjects was associated with estimated incremental cost-effectiveness ratios of 7,773,063 Korean won (KRW) per quality-adjusted life-year gained and 10,378,230 KRW per overall life-year gained (1300 KRW approximately US $1). Sensitivity and uncertainty analyses indicated these results to be robust. In this model, based on data from the 2005 KNHNES, hypertension and dyslipidemia were undertreated among Koreans aged > or = 45 years without a history of MI or stroke. The administration of single-tablet fixed-dose combination amlodipine and atorvastatin to all such individuals was likely to represent a cost-effective means of preventing first-onset CVD (ie, coronary heart disease and ischemic stroke) in this subgroup, compared with current patterns of treatment.

[A comparative study on Koii (public doctor) system and its effect on public health in colonial Taiwan and Korea].

Koii(Public Doctor) System introduced into Taiwan in 1896 for the purpose of filling up medical vacuum of rural area and therefore spreading modern medical system all over Taiwan, was transplanted in 1913 into Colonial Korea for the same purpose. In terms of system itself Koii system in both areas were almost the same, but quite different in practices. First, Koiis in Taiwan was forced to write concrete medical report every month on the medical situation in the area under jurisdiction, whereas to those in Korea writing monthly report was not so compulsory. This difference resulted in some gaps in the quality of medical statistics of the two areas. Second, Unlike their counterparts in Korea, Koiis in Taiwan organized their own associations both locally and nationally and it helped to build up their own networks and share informations on medical situation including informations on infectious diseases. Third, Koiis in Taiwan formed more harmonious relationship between Taiwanese Police than their counterparts in Korea, which helped them to execute various medical activities in more comfortable environment. Taiwanese People went to medical institutions a lot more frequently than Korean People, and this difference was basically derived from the quite different density of Koii assignment in both areas. Korean People had to spend more time and money to utilize modern medical institutions than Taiwanese People did. The different density of Koii assignment also affected the results of prevention and eradication of infectious diseases; in Taiwan plague and small-pox has been successfully controled, whereas Chosun Government general was not so successful in controling infectious diseases including small-pox. Small-pox infected in Korea was about 6 times to Taiwan, and the number of death by small-pox was 9 times to Taiwan. One of the keys to this difference is the different role of Koiis. In Korea, Koiis could do little thing about infectious diseases mainly because of manpower shortage, thus shifting their duties like vaccination onto police officers who was inevitably inferior to doctors in medical terms, whereas vaccination was led by Koiis in Taiwan, with the help of police officers and traditional doctors. The difference between Korea and Taiwan in terms of Koii system and its effect implies that public health network in colonial Taiwan was better organized and more stable than that in colonial Korea, and therefore we should be careful about applying the concept of disciplinary power or modernization theory to colonial medical history of Korea.

[The introduction of tobacco and the diffusion of smoking culture in Korea].

Since its introduction to Korea from Japan at the beginning of the seventeenth century, tobacco became very popular with an amazing rapidity among Koreans. Along with widespread cultivation of tobacco, smoking also became very popular among Koreans, regardless of their classes, ages, and sexes. On the other hand, other imported crops from America via Europe in the sam period, like sweet potato, potato, corn and tomato, did not enjoy such popularity in Korea. A long time after their introduction, Koreans began to cultivate these crops. Why did Koreans respond enthusiastically to the newly-imported tobacco? What kind of factors contributed to the rapid transmission of tobacco in Korea? This study examined the causes of rapid diffusion of the smoking population in three aspects. First was economic aspect. The farming of tobacco yielded a profit by selling it to Chinese. The climate and the soil of Korea fit for farming of tobacco. So the farm land of tobacco expanded gradually since the 18th century. Second was medical aspect. At first, many Koreans believed that smoking was helpful to digestion, expectoration, protecting coldness, and exterminating parasites. Afterwards, they believed smoking could encourage vitality and protect diseases. There was no reason of smoking cessation for the people's health in that the hazards of smoking were not well known to the commonage in those days, though a few intellectuals acknowledge its harm. Third was sociocultural aspect. We could trace the smoking culture of Chosun dynasty through arts, poems, and essays. The making of smoking culture made stable reproduction of smokers generation by generation. Especially, the smoking culture secured juvenile's smoking. Considering the three aspects above, we know that what reason the Decree of Ban of Smoking in Korea was not strict in comparison to that of China (Qing Dynasty), in which the violators were executed. The regulation of smoking by the government failed except controlling in sociocultural aspect. The government reinforced controlling of smoking culture in counteraction to the threat of collapse of the hierarchy of Chosun dynasty in 18th century.

This longitudinal study aimed to identify the relevant factors related to quality of life (QoL) changes in medical students. For this 6-month follow-up study, we enrolled 109 students from a Korean medical school. To assess students' QoL, we used the World Health Organization QoL scale. Possible determinants of student QoL included demographics, fatigue, and social support. A stepwise multivariate analysis identified factors associated with changes of student QoL. Among sources of support, the "friends" category was the main position affecting their overall QoL, and "significant other" had the strongest influence on psychological and social domains. The impact of support from friends on QoL was confirmed in the longitudinal analysis. Final regression models revealed that providing students with more social support and promoting fatigue reduction best improved medical student sense of well-being. Creating stronger student support programs to prevent social detachment and implementing strategies to reduce fatigue can improve QoL in medical students.

Using diagnosis code-based algorithms is the primary method of identifying patient cohorts for retrospective studies; nevertheless, many databases lack reliable diagnosis code information. To develop precise algorithms based on medication claims/prescriber visits (MCs/PVs) to identify psoriasis (PsO) patients and psoriatic patients with arthritic conditions (PsO-AC), a proxy for psoriatic arthritis, in Canadian databases lacking diagnosis codes. Algorithms were developed using medications with narrow indication profiles in combination with prescriber specialty to define PsO and PsO-AC. For a 3-year study period from July 1, 2009, algorithms were validated using the PharMetrics Plus database, which contains both adjudicated medication claims and diagnosis codes. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of the developed algorithms were assessed using diagnosis code as the reference standard. Chosen algorithms were then applied to Canadian drug databases to profile the algorithm-identified PsO and PsO-AC cohorts. In the selected database, 183,328 patients were identified for validation. The highest PPVs for PsO (85%) and PsO-AC (65%) occurred when a predictive algorithm of two or more MCs/PVs was compared with the reference standard of one or more diagnosis codes. NPV and specificity were high (99%-100%), whereas sensitivity was low (≤30%). Reducing the number of MCs/PVs or increasing diagnosis claims decreased the algorithms' PPVs. We have developed an MC/PV-based algorithm to identify PsO patients with a high degree of accuracy, but accuracy for PsO-AC requires further investigation. Such methods allow researchers to conduct retrospective studies in databases in which diagnosis codes are absent.

Crohn's disease (CD) is a chronic, progressive, and disabling inflammatory bowel disease (IBD) with an uncertain etiopathogenesis. CD can involve any site of the gastrointestinal tract from the mouth to the anus, and is associated with serious complications, such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower compared with those in Western countries, but they have been rapidly increasing during the recent decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies have been applied for the treatment of this disease. Concerning CD management, there have been substantial discrepancies among clinicians according to their personal experience and preference. To suggest recommendable approaches to the diverse problems of CD and to minimize the variations in treatment among physicians, guidelines for the management of CD were first published in 2012 by the IBD Study Group of the Korean Association for the Study of Intestinal Diseases. These are the revised guidelines based on updated evidence, accumulated since 2012. These guidelines were developed by using mainly adaptation methods, and encompass induction and maintenance treatment of CD, treatment based on disease location, treatment of CD complications, including stricture and fistula, surgical treatment, and prevention of postoperative recurrence. These are the second Korean guidelines for the management of CD and will be continuously revised as new evidence is collected. PMID:28239314

To investigate the completeness of pedigree and of number of pedigree analysis to know the acceptable familial history in Korean women with ovarian cancer. Interview was conducted in 50 ovarian cancer patients for obtaining familial history three times over the 6 weeks. The completeness of pedigree is estimated in terms of familial history of disease (cancer), health status (health living, disease and death), and onset age of disease and death. The completion of pedigree was 79.3, 85.1, and 85.6% at the 1st, 2nd, and 3rd time of interview and the time for pedigree analysis was 34.3, 10.8, and 3.1 minutes, respectively. The factors limiting pedigree analysis were as follows: out of contact with their relatives (38%), no living ancestors who know the family history (34%), dispersed family member because of the Korean War (16%), unknown cause of death (12%), reluctance to ask medical history of relatives (10%), and concealing their ovarian cancer (10%). The percentage of cancers revealed in 1st (2%) and 2nd degree (8%) relatives were increasing through surveys, especially colorectal cancer related with Lynch syndrome (4%). Analysis of pedigree at least two times is acceptable in Korean woman with ovarian cancer from the first study. The completion of pedigree is increasing, while time to take family history is decreasing during three time survey.

The purpose of this study is to establish a reference for image acquisition for completing a standard brain for diverse Korean population, and to develop database management system that saves and manages acquired brain images and personal information of subjects. 3D MP-RAGE (Magnetization Prepared Rapid Gradient Echo) technique which has excellent Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) as well as reduces image acquisition time was selected for anatomical image acquisition, and parameter values were obtained for the optimal image acquisition. Using these standards, image data of 121 young adults (early twenties) were obtained and stored in the system. System was designed to obtain, save, and manage not only anatomical image data but also subjects' basic demographic factors, medical history, handedness inventory, state-trait anxiety inventory, A-type personality inventory, self-assessment depression inventory, mini-mental state examination, intelligence test, and results of personality test via a survey questionnaire. Additionally this system was designed to have functions of saving, inserting, deleting, searching, and printing image data and personal information of subjects, and to have accessibility to them as well as automatic connection setup with ODBC. This newly developed system may have major contribution to the completion of a standard brain for diverse Korean population since it can save and manage their image data and personal information.

Growth status of Korean orphans raised in the affluent West: anthropometric trend, multivariate determinants, and descriptive comparison with their North and South Korean peers.

This paper investigates the trend in height among adult Korean orphans who were adopted in early life into affluent Western nations. Final heights of 148 females were analyzed based on a Korean government survey conducted in 2008. Height of the orphans was descriptively compared against final heights of South and North Koreans. Furthermore, statistical determinants of orphan height were investigated in multivariate regressions. Mean height of Korean orphans was 160.44 cm (SD 5.89), which was higher than that of South Koreans at 158.83 cm (SD 5.01). Both Korean orphans and South Koreans were taller than North Koreans at 155.30 cm (SD 4.94). However, height of Korean orphans stagnated at around 160-161 cm while those of North and South Koreans improved over time. In the regression analysis, the socioeconomic status of the adoptive family was statistically significant in all models, while dummies for the adoptive nations and age at adoption were insignificant. This study shows that the mean final height of women experiencing extreme environmental improvements in early-life is capped at 160-161 cm, tentatively suggesting that social stress factors in the host nation or early-life factors in the birth nation might have offset some of the environmental enrichment effects achieved through intercountry adoption.

The psychometric properties in the Korean version of the IdFAI were measured for test-retest reliability, internal consistency, criterion-related validity, discriminative validity, and measurement error 181 native Korean-speakers. Intra-class correlation coefficients (ICC 2,1 ) between the English and Korean versions of the IdFAI for test-retest reliability was 0.98 (standard error of measurement = 1.41). The Cronbach's alpha coefficient was 0.89 for the Korean versions of IdFAI. The Korean versions of the IdFAI had a strong correlation with the SF-36 (r s  = -0.69, p < .001) and the Korean version of the Cumberland Ankle Instability Tool (r s  = -0.65, p < .001). The cutoff score of >10 was the optimal cutoff score to distinguish between the group memberships. The minimally detectable change of the Korean versions of the IdFAI score was 3.91. The Korean versions of the IdFAI have shown to be an excellent, reliable, and valid instrument. The Korean versions of the IdFAI can be utilized to assess the presence of Chronic Ankle Instability by researchers and clinicians working among Korean-speaking populations. Implications for rehabilitation The high recurrence rate of sprains may result into Chronic Ankle Instability (CAI). The Identification of Functional Ankle Instability Tool (IdFAI) has been validated and recommended to identify patients with Chronic Ankle Instability (CAI). The Korean version of the Identification of Functional Ankle Instability Tool (IdFAI) may be also recommend to researchers and clinicians for assessing the presence of Chronic Ankle Instability (CAI) in Korean-speaking population.

This study examined a cultural response set to positive affect items and depressive symptom items in CES-D among 172 Korean immigrants. Bi-dimensional acculturation approach, which considers maintenance of Korean Orientation and adoption of American Orientation, was utilized. As Korean immigrants increased American Orientation, they tended to score higher on positive affect items, while no changes occurred in depressive symptom items. Korean Orientation was not related to either positive affect items or depressive symptom items. Korean immigrants have response bias toward positive affect items in CES-D, which decreases as they adopt more American Orientation. CES-D lacks cultural equivalence for Korean immigrants.

An efficient dictionary learning algorithm and its application to 3-D medical image denoising.

PubMed

Li, Shutao; Fang, Leyuan; Yin, Haitao

2012-02-01

In this paper, we propose an efficient dictionary learning algorithm for sparse representation of given data and suggest a way to apply this algorithm to 3-D medical image denoising. Our learning approach is composed of two main parts: sparse coding and dictionary updating. On the sparse coding stage, an efficient algorithm named multiple clusters pursuit (MCP) is proposed. The MCP first applies a dictionary structuring strategy to cluster the atoms with high coherence together, and then employs a multiple-selection strategy to select several competitive atoms at each iteration. These two strategies can greatly reduce the computation complexity of the MCP and assist it to obtain better sparse solution. On the dictionary updating stage, the alternating optimization that efficiently approximates the singular value decomposition is introduced. Furthermore, in the 3-D medical image denoising application, a joint 3-D operation is proposed for taking the learning capabilities of the presented algorithm to simultaneously capture the correlations within each slice and correlations across the nearby slices, thereby obtaining better denoising results. The experiments on both synthetically generated data and real 3-D medical images demonstrate that the proposed approach has superior performance compared to some well-known methods. © 2011 IEEE

Depression and Korean American immigrants.

PubMed

Park, So-Youn; Bernstein, Kunsook Song

2008-02-01

Koreans are a relatively new and fast-growing immigrant group in the United States. Research has shown that immigration experiences are associated with depression, whereas acculturation and social support are moderating factors. Korean culture is informed by Confucianism, which emphasizes family integrity, group conformity, and traditional gender roles, and has influenced how Korean immigrants conceptualize depression, express depressive symptoms, and demonstrate help-seeking behavior. An understanding of Korean patterns of manifesting and expressing depression will be helpful to provide culturally appropriate mental health services to Korean American immigrants.

A hybrid flower pollination algorithm based modified randomized location for multi-threshold medical image segmentation.

2015-01-01

Multi-threshold image segmentation is a powerful image processing technique that is used for the preprocessing of pattern recognition and computer vision. However, traditional multilevel thresholding methods are computationally expensive because they involve exhaustively searching the optimal thresholds to optimize the objective functions. To overcome this drawback, this paper proposes a flower pollination algorithm with a randomized location modification. The proposed algorithm is used to find optimal threshold values for maximizing Otsu's objective functions with regard to eight medical grayscale images. When benchmarked against other state-of-the-art evolutionary algorithms, the new algorithm proves itself to be robust and effective through numerical experimental results including Otsu's objective values and standard deviations.

The influence of culture on the experiences of Korean, Korean American, and Caucasian-American family caregivers of frail older adults: a literature review.

PubMed

Kong, Eun-Hi

2007-03-01

The purpose of this review is to explore cultural influences on the experiences of Korean, Korean American, and Caucasian American family caregivers caring for frail older adults in terms of the selection of a primary caregiver, caregiving motivation, support/help-seeking, and negative emotional responses(depression and burden). Seven electronic databases were searched to retrieve studies from 1966 to 2005. Thirty-two studies were identified. This review supported cultural influences on the selection of primary caregiver, caregiving motivation, and support/help-seeking among the three caregiver groups. In Korean caregivers, the major primary caregivers were daughters-in-law while among Korean American and Caucasian American caregivers, the major primary caregivers were daughters or spouses. As a major caregiving motivation, Caucasian American caregivers reported filial affection while Korean caregivers and Korean American caregivers reported filial obligation. Korean caregivers reported higher extended family support, while Caucasian American caregivers reported higher utilization of formal support. Korean caregivers showed the highest levels of depression followed by Korean American caregivers and Caucasian American caregivers. In order to develop culturally appropriate interventions and policies, more research is needed to further explain these differences among the three groups, especially regarding support/help-seeking and negative emotional responses.

Electronic Medical Records (EMRs) are increasingly used in the provision of primary care and have been compiled into databases which can be utilized for surveillance, research and informing practice. The primary purpose of these records is for the provision of individual patient care; validation and examination of underlying limitations is crucial for use for research and data quality improvement. This study examines and describes the validity of chronic disease case definition algorithms and factors affecting data quality in a primary care EMR database. A retrospective chart audit of an age stratified random sample was used to validate and examine diagnostic algorithms applied to EMR data from the Manitoba Primary Care Research Network (MaPCReN), part of the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). The presence of diabetes, hypertension, depression, osteoarthritis and chronic obstructive pulmonary disease (COPD) was determined by review of the medical record and compared to algorithm identified cases to identify discrepancies and describe the underlying contributing factors. The algorithm for diabetes had high sensitivity, specificity and positive predictive value (PPV) with all scores being over 90%. Specificities of the algorithms were greater than 90% for all conditions except for hypertension at 79.2%. The largest deficits in algorithm performance included poor PPV for COPD at 36.7% and limited sensitivity for COPD, depression and osteoarthritis at 72.0%, 73.3% and 63.2% respectively. Main sources of discrepancy included missing coding, alternative coding, inappropriate diagnosis detection based on medications used for alternate indications, inappropriate exclusion due to comorbidity and loss of data. Comparison to medical chart review shows that at MaPCReN the CPCSSN case finding algorithms are valid with a few limitations. This study provides the basis for the validated data to be utilized for research and informs users of its limitations. Analysis of underlying discrepancies provides the ability to improve algorithm performance and facilitate improved data quality.

An empirical comparative study on biological age estimation algorithms with an application of Work Ability Index (WAI).

PubMed

Cho, Il Haeng; Park, Kyung S; Lim, Chang Joo

2010-02-01

In this study, we described the characteristics of five different biological age (BA) estimation algorithms, including (i) multiple linear regression, (ii) principal component analysis, and somewhat unique methods developed by (iii) Hochschild, (iv) Klemera and Doubal, and (v) a variant of Klemera and Doubal's method. The objective of this study is to find the most appropriate method of BA estimation by examining the association between Work Ability Index (WAI) and the differences of each algorithm's estimates from chronological age (CA). The WAI was found to be a measure that reflects an individual's current health status rather than the deterioration caused by a serious dependency with the age. Experiments were conducted on 200 Korean male participants using a BA estimation system developed principally under the concept of non-invasive, simple to operate and human function-based. Using the empirical data, BA estimation as well as various analyses including correlation analysis and discriminant function analysis was performed. As a result, it had been confirmed by the empirical data that Klemera and Doubal's method with uncorrelated variables from principal component analysis produces relatively reliable and acceptable BA estimates. 2009 Elsevier Ireland Ltd.

2012-01-01

A new fuzzy based thresholding method for medical images especially cervical cytology images having blob and mosaic structures is proposed in this paper. Many existing thresholding algorithms may segment either blob or mosaic images but there aren't any single algorithm that can do both. In this paper, an input cervical cytology image is binarized, preprocessed and the pixel value with minimum Fuzzy Gaussian Index is identified as an optimal threshold value and used for segmentation. The proposed technique is tested on various cervical cytology images having blob or mosaic structures, compared with various existing algorithms and proved better than the existing algorithms.

Novel medical image enhancement algorithms

NASA Astrophysics Data System (ADS)

Agaian, Sos; McClendon, Stephen A.

2010-01-01

In this paper, we present two novel medical image enhancement algorithms. The first, a global image enhancement algorithm, utilizes an alpha-trimmed mean filter as its backbone to sharpen images. The second algorithm uses a cascaded unsharp masking technique to separate the high frequency components of an image in order for them to be enhanced using a modified adaptive contrast enhancement algorithm. Experimental results from enhancing electron microscopy, radiological, CT scan and MRI scan images, using the MATLAB environment, are then compared to the original images as well as other enhancement methods, such as histogram equalization and two forms of adaptive contrast enhancement. An image processing scheme for electron microscopy images of Purkinje cells will also be implemented and utilized as a comparison tool to evaluate the performance of our algorithm.

A sketch of language history in the Korean Peninsula.

PubMed

Lee, Sean

2015-01-01

Among 7100 languages spoken on Earth, the Koreanic language is the 13th largest, with about 77 million speakers in and around the Korean Peninsula. In comparison to other languages of similar size, however, surprisingly little is known about the evolution of the Koreanic language. This is mainly due to two reasons. The first reason is that the genealogical relationship of the Koreanic to other neighboring languages remains uncertain, and thus inference from the linguistic comparative method provides only provisional evidence. The second reason is that, as the ancestral Koreanic speakers lacked their own writing system until around 500 years ago, there are scant historical materials to peer into the past, except for those preserved in Sinitic characters that we have no straightforward way of interpreting. Here I attempt to overcome these disadvantages and shed some light on the linguistic history of the Korean Peninsula, by analyzing the internal variation of the Koreanic language with methods adopted from evolutionary biology. The preliminary results presented here suggest that the evolutionary history of the Koreanic language is characterized by a weak hierarchical structure, and intensive gene/culture flows within the Korean Peninsula seem to have promoted linguistic homogeneity among the Koreanic variants. Despite the gene/culture flows, however, there are still three detectable linguistic barriers in the Korean Peninsula that appear to have been shaped by geographical features such as mountains, elevated areas, and ocean. I discuss these findings in an inclusive manner to lay the groundwork for future studies.

The Korean National Health Insurance (NHI) system was an unprecedented accomplishment that was achieved in a short period of time. In this study, we sought to identify gaps between physicians and the public with respect to attitudes toward the NHI system in Korea. The study population was derived from the 2008 Korean Medical Association Survey, which was conducted to investigate satisfaction with and perceptions of the NHI system among physicians (n = 961) and the public (n = 935). Only 6.5% of the physicians were satisfied with NHI system, and 71.5% were dissatisfied with it. In contrast, 28.3% of the public were satisfied with the NHI system, and 21.4% were dissatisfied. The level of dissatisfaction expressed by physicians (2.03 ± 0.91 on a five-point scale) was also higher than that expressed by the public (3.06 ± 0.84). Despite rapid growth of NHI system, a large gap in satisfaction exists between physicians and the public. PMID:22690087

The emergence of a health insurance system in a developing country: the case of South Korea.

PubMed

Cho, S

1989-12-01

In an attempt to understand the social forces and the economic and political conditions under which new social policies emerge in developing countries, this study outlines factors affecting the introduction of the health insurance system in South Korea. The emergence of the South Korean health insurance system was influenced by changing labor needs of the industrial sector, increasing social expectations, external and international pressures, increasing medical costs, and class conflict. These pressures compelled the South Korean government to respond to demands for the introduction of new social welfare policies in the 1970s. In the case of South Korea, the new health insurance system resulted from the government's attempts to cope with political, economic, and social pressures rather than from an ideological commitment to the well-being of the population. The resulting insurance system was a way to maintain the social order and legitimacy of the regime, and a means to promote the health of groups important to defense or production.

Alopecic and aseptic nodule of the scalp (AANS) is a rare disease entity first reported in 1992 as pseudocyst of the scalp (PCS). Controversy exists regarding the histopathology and etiology of reported cases. We performed this study to analyze the clinical and histopathologic features of AANS/PCS in Korean patients. A retrospective review of medical records from 2008 to 2013 at Inje University Busan Paik Hospital was performed. Eleven patients were enrolled. All patients were male, and their mean age was 21.6 years. Most patients had a solitary nodule (10/11) located predominantly on the vertex. The mean nodule size was 20 mm. Inflammatory cell infiltration in the deep dermis was a histologic feature of AANS/PCS. Eight patients showed granulomatous infiltration. All patients were treated with short-term antibiotics and intralesional steroid injection. Our results suggest that dermatologists should consider AANS when diagnosing an alopecic nodule on the scalp. © 2015 S. Karger AG, Basel.

A new approach to more accurately monitor and evaluate transboundary particulate matter (PM) pollution is introduced based on aerosol optical products from Korea's Geostationary Ocean Color Imager (GOCI). The area studied is Northeast Asia (including eastern parts of China, the Korean peninsula and Japan), where GOCI has been monitoring since June 2010. The hourly multi-spectral aerosol optical data that were retrieved from GOCI sensor onboard geostationary satellite COMS (Communication, Ocean, and Meteorology Satellite) through the Yonsei aerosol retrieval algorithm were first presented and used in this study. The GOCI-retrieved aerosol optical data are integrated with estimated aerosol distributions from US EPA Models-3/CMAQ (Community Multi-scale Air Quality) v4.5.1 model simulations via data assimilation technique, thereby making the aerosol data spatially continuous and available even for cloud contamination cells. The assimilated aerosol optical data are utilized to provide quantitative estimates of transboundary PM pollution from China to the Korean peninsula and Japan. For the period of 1 April to 31 May, 2011 this analysis yields estimates that AOD as a proxy for PM2.5 or PM10 during long-range transport events increased by 117-265% compared to background average AOD (aerosol optical depth) at the four AERONET sites in Korea, and average AOD increases of 121% were found when averaged over the entire Korean peninsula. This paper demonstrates that the use of multi-spectral AOD retrievals from geostationary satellites can improve estimates of transboundary PM pollution. Such data will become more widely available later this decade when new sensors such as the GEMS (Geostationary Environment Monitoring Spectrometer) and GOCI-2 are scheduled to be launched.

Lossless medical image compression using geometry-adaptive partitioning and least square-based prediction.

2018-06-01

To improve the compression rates for lossless compression of medical images, an efficient algorithm, based on irregular segmentation and region-based prediction, is proposed in this paper. Considering that the first step of a region-based compression algorithm is segmentation, this paper proposes a hybrid method by combining geometry-adaptive partitioning and quadtree partitioning to achieve adaptive irregular segmentation for medical images. Then, least square (LS)-based predictors are adaptively designed for each region (regular subblock or irregular subregion). The proposed adaptive algorithm not only exploits spatial correlation between pixels but it utilizes local structure similarity, resulting in efficient compression performance. Experimental results show that the average compression performance of the proposed algorithm is 10.48, 4.86, 3.58, and 0.10% better than that of JPEG 2000, CALIC, EDP, and JPEG-LS, respectively.

Origins and Evolution of Social Medicine and Contemporary Social Medicine in Korea.

2017-01-01

Social medicine is recognized as one of medical specialties in many countries. However, social medicine has never been formally introduced to Korea, presumably because the term and its principles were not accepted for some years in the past in American medicine, which has strongly influenced Korean medicine. This paper describes the origins and evolution of social medicine and briefly discusses contemporary social medicine in Korea. Social medicine was initiated in France and Germany in 1848. Since then, it has expanded globally and developed in diverse ways. Included in core principles of social medicine is that social and economic conditions have important effects on health and disease, and that these relationships must be subjected to scientific investigation. The term 'social medicine' is rarely used in Korea, but many of its subject matters are incorporated into preventive medicine which, besides prevention, deals with population health that is inescapably social. However, the Korean preventive medicine directs little attention to the basic concepts and principles of social medicine, upon which systematic development of social medicine can be based. Thus, it is necessary to supplement the social medicine contents of preventive medicine through formalizing the linkages between the two fields. One way of doing so would be to change the title of 'preventive medicine' course in medical colleges to 'preventive and social medicine,' as in many other countries, and to adjust the course contents accordingly.

Understanding the magnitude of the economic impact of an illness on society is fundamental to planning and implementing relevant policies. South Korea operates a compulsory universal health insurance system providing favorable conditions for evaluating the nationwide economic burden of illnesses. The aim of this study was to estimate the economic costs of asthma imposed on Korean society. The Korean National Health Insurance claims database was used for determining the health care services provided to asthma patients defined as having at least one inpatient or outpatient claim(s) with a primary diagnosis of asthma in 2008. Both direct and indirect costs were included. Direct costs were those associated directly with treatment, medication, and transportation. Indirect costs were assessed in terms of the loss of productivity in asthma patients and their caregivers and consisted of morbidity cost, mortality cost, and caregivers' time cost. The estimated cost for 2,273,290 asthma patients in 2008 was $831 million, with an average per capita cost of $336. Among the cost components, outpatient and medication costs represented the largest cost burden. Although the costs for children accounted for the largest proportion of the total cost, the per capita cost was highest among patients ≥50 years old. The economic burden of asthma in Korea is considerable. Considering that the burden will increase with the rising prevalence, implementation of effective national prevention approaches aimed at the appropriate target populations is imperative.

To examine the changes in pain, disability, and quality of life in motor vehicle collision injury (MVCI) patients after treatment with traditional Korean medicine (TKM), and to investigate the psychological characteristics of these patients. Forty-one patients with MVCI were treated with TKM including acupuncture, pharmacopuncture, moxibustion, cupping, herbal medication, chuna manual therapy, and physical therapy. Numeric Rating Scale (NRS), Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), Neck Disability Index (NDI), Oswestry Disability Index (ODI), and Lysholm Knee Scoring Scale were assessed at admission and discharge. The Minnesota Multiphasic Personality Inventory (MMPI) was assessed at admission. After treatment, NRS scores for headache, cervical pain, and lumbar pain were significantly decreased (P<0.05); NDI, ODI scores were significantly decreased, and Lysholm score was signifificantly increased (P<0.05). The following SF-36 scores were signifificantly increased: physical and mental component summary, bodily pain, role-physical, role-emotional, social functioning, and mental health scores (all P<0.05). MMPI identifified 3-1 profifile conversion V shape. Treatment of MVCI with TKM provided effective management of complex symptoms such as pain, disability, and loss of quality of life. A comprehensive plan must be implemented for treatment and research in cases of MVCIs owing to the correlation between physical symptoms and psychological profifiles.

Background Atopic dermatitis is a global public health concern owing to its increasing prevalence and socioeconomic burden. However, few studies have assessed the economic impact of atopic dermatitis in Korea. Objective We conducted a cost analysis of atopic dermatitis and evaluated its economic impacts on individual annual disease burden, quality of life, and changes in medical expenses with respect to changes in health related-quality of life. Methods The cost analysis of atopic dermatitis was performed by reviewing the home accounting records of 32 patients. The economic impact of the disease was evaluated by analyzing questionnaires. To handle uncertainties, we compared the results with the data released by the Health Insurance Review & Assessment Board on medical costs claimed by healthcare facilities. Results The direct cost of atopic dermatitis per patient during the 3-month study period was 541,280 Korean won (KRW), and expenditures on other atopic dermatitis-related products were 120,313 KRW. The extrapolated annual direct cost (including expenditures on other atopic dermatitis-related products) per patient was 2,646,372 KRW. The estimated annual indirect cost was 1,507,068 KRW. Thus, the annual cost of illness of atopic dermatitis (i.e., direct+indirect costs) was estimated to be 4,153,440 KRW. Conclusion The annual total social cost of atopic dermatitis on a national level is estimated to be 5.8 trillion KRW. PMID:26082587

Varying levels of difficulty index of skills-test items randomly selected by examinees on the Korean emergency medical technician licensing examination

2016-01-01

Purpose: The goal of this study was to characterize the difficulty index of the items in the skills test components of the class I and II Korean emergency medical technician licensing examination (KEMTLE), which requires examinees to select items randomly. Methods: The results of 1,309 class I KEMTLE examinations and 1,801 class II KEMTLE examinations in 2013 were subjected to analysis. Items from the basic and advanced skills test sections of the KEMTLE were compared to determine whether some were significantly more difficult than others. Results: In the class I KEMTLE, all 4 of the items on the basic skills test showed significant variation in difficulty index (P<0.01), as well as 4 of the 5 items on the advanced skills test (P<0.05). In the class II KEMTLE, 4 of the 5 items on the basic skills test showed significantly different difficulty index (P<0.01), as well as all 3 of the advanced skills test items (P<0.01). Conclusion: In the skills test components of the class I and II KEMTLE, the procedure in which examinees randomly select questions should be revised to require examinees to respond to a set of fixed items in order to improve the reliability of the national licensing examination.

2012-05-01

A 24-year-old man presented with mental change, fever, abdominal pain, tenderness and palpable mass on the lower abdomen. He was a non-Korean engineer and did not accompany a legal guardian, so medical history taking was difficult due to his mental status. Brain magnetic resonance imaging showed multiple rim-enhanced lesions of the brain, and abdominal computed tomography showed huge paraspinal abscess. Chest X-ray and computed tomography showed poorly defined nodular opacities. We initially thought that this patient was infected with toxoplasmosis with typical cerebral image finding and immunoglobulin laboratory finding of cerebrospinal fluid and serum study. The abdominal abscess was confirmed as tuberculosis through the pathologic finding of caseous necrosis. We used anti-tuberculosis medication and anti-toxoplasmosis medication for almost 4 months, and then his clinical state and radiological findings were considerably improved.

Stochastic resource allocation in emergency departments with a multi-objective simulation optimization algorithm.

PubMed

Feng, Yen-Yi; Wu, I-Chin; Chen, Tzu-Li

2017-03-01

The number of emergency cases or emergency room visits rapidly increases annually, thus leading to an imbalance in supply and demand and to the long-term overcrowding of hospital emergency departments (EDs). However, current solutions to increase medical resources and improve the handling of patient needs are either impractical or infeasible in the Taiwanese environment. Therefore, EDs must optimize resource allocation given limited medical resources to minimize the average length of stay of patients and medical resource waste costs. This study constructs a multi-objective mathematical model for medical resource allocation in EDs in accordance with emergency flow or procedure. The proposed mathematical model is complex and difficult to solve because its performance value is stochastic; furthermore, the model considers both objectives simultaneously. Thus, this study develops a multi-objective simulation optimization algorithm by integrating a non-dominated sorting genetic algorithm II (NSGA II) with multi-objective computing budget allocation (MOCBA) to address the challenges of multi-objective medical resource allocation. NSGA II is used to investigate plausible solutions for medical resource allocation, and MOCBA identifies effective sets of feasible Pareto (non-dominated) medical resource allocation solutions in addition to effectively allocating simulation or computation budgets. The discrete event simulation model of ED flow is inspired by a Taiwan hospital case and is constructed to estimate the expected performance values of each medical allocation solution as obtained through NSGA II. Finally, computational experiments are performed to verify the effectiveness and performance of the integrated NSGA II and MOCBA method, as well as to derive non-dominated medical resource allocation solutions from the algorithms.

We investigated the performance of North Korean refugees on attention tasks, and the relationship between that performance and psychiatric symptoms. Sustained and divided attention was assessed using the computerized Comprehensive Attention Test in North Korean refugees and in South Koreans. All participants also completed the Beck Depression Inventory, the Beck Anxiety Inventory, the Impact of Event Scale-Revised and the Dissociative Experiences Scale-II (DES-II). The North Korean refugees showed slower reaction times (RTs) on the visual sustained attention task compared to the South Koreans after controlling for age and sex. North Korean refugees had a greater number of omission errors (OEs) on the divided attention task and a higher standard deviation (SD) of RT. Total DES-II scores of the North Korean refugees were associated with the number of OEs and the SD of RT on the sustained attention task, and with the number of OEs on the divided attention task. North Korean refugees showed poorer performance on computerized attention tasks. In addition, attention deficit among North Korean refugees was associated with their dissociative experiences. Our results suggest that refugees may have attention deficits, which may be related to their psychiatric symptoms, particularly dissociation.

The number of North Korean adolescent defectors entering South Korea has been increasing. The health behavior, including mental health-related behavior, and factors associated with depression in North Korean adolescent defectors residing in South Korea were investigated. Data obtained from the Korea Youth Risk Behavior Web-Based Survey (2011-2014) dataset were utilized. In total, 206 North Korean adolescent defectors were selected, and for the control group, 618 matched South Korean adolescents were selected. Frequency analysis was used to determine the place of birth and nationality of the parents, chi-square tests were used to compare the general characteristics of the North and South Korean subjects, and multivariate logistic regressions were conducted to compare the health behavior of the two sets of subjects. To determine the factors associated with depression in the North Korean subjects, a logistic regression was performed. The North Korean adolescents reported higher current smoking (adjusted odds ratio [aOR], 2.54; 95% confidence interval [CI], 1.48 to 4.35), current drinking (aOR, 1.85; 95% CI, 1.15 to 2.99), and drug use rates (aOR, 10.99; 95% CI, 4.04 to 29.88) than did the South Korean adolescents. The factors associated with depression in the North Korean adolescents were current smoking (aOR, 6.99; 95% CI, 1.62 to 30.06), lifetime drinking experience (aOR, 5.32; 95% CI, 1.51 to 18.75), and perceived stress (aOR, 4.74; 95% CI, 1.74 to 12.90). There were differences in health behavior between the North and South Korean adolescents. A specialized approach for North Korean adolescent defectors is required to promote proper health behavior and adaptation to South Korean society.

Intelligent Medical Systems for Aerospace Emergency Medical Services

The purpose of this project is to develop a portable, hands free device for emergency medical decision support to be used in remote or confined settings by non-physician providers. Phase I of the project will entail the development of a voice-activated device that will utilize an intelligent algorithm to provide guidance in establishing an airway in an emergency situation. The interactive, hands free software will process requests for assistance based on verbal prompts and algorithmic decision-making. The device will allow the CMO to attend to the patient while receiving verbal instruction. The software will also feature graphic representations where it is felt helpful in aiding in procedures. We will also develop a training program to orient users to the algorithmic approach, the use of the hardware and specific procedural considerations. We will validate the efficacy of this mode of technology application by testing in the Johns Hopkins Department of Emergency Medicine. Phase I of the project will focus on the validation of the proposed algorithm, testing and validation of the decision making tool and modifications of medical equipment. In Phase 11, we will produce the first generation software for hands-free, interactive medical decision making for use in acute care environments.

An algorithm that detects errors in diagnosis, classification or coding of diabetes in primary care computerised medial record (CMR) systems is currently available. However, this was developed on CMR systems that are episode orientated medical records (EOMR); and do not force the user to always code a problem or link data to an existing one. More strictly problem orientated medical record (POMR) systems mandate recording a problem and linking consultation data to them. To compare the rates of detection of diagnostic accuracy using an algorithm developed in EOMR with a new POMR specific algorithm. We used data from The Health Improvement Network (THIN) database (N = 2,466,364) to identify a population of 100,513 (4.08%) patients considered likely to have diabetes. We recalibrated algorithms designed to classify cases of diabetes to take account of that POMR enforced coding consistency in the computerised medical record systems [In Practice Systems (InPS) Vision] that contribute data to THIN. We explored the different proportions of people classified as having type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) and with diabetes unclassifiable as either T1DM or T2DM. We compared proportions using chi-square tests and used Tukey's test to compare the characteristics of the people in each group. The prevalence of T1DM using the original EOMR algorithm was 0.38% (9,264/2,466,364), and for T2DM 3.22% (79,417/2,466,364). The prevalence using the new POMR algorithm was 0.31% (7,750/2,466,364) T1DM and 3.65% (89,990/2,466,364) T2DM. The EOMR algorithms also left more people unclassified 11,439 (12%), as to their type of diabetes compared with 2,380 (2.4%), for the new algorithm. Those people who were only classified by the EOMR system differed in terms of older age, and apparently better glycaemic control, despite not being prescribed medication for their diabetes (p < 0.005). Increasing the degree of problem orientation of the medical record system can improve the accuracy of recording of diagnoses and, therefore, the accuracy of using routinely collected data from CMRs to determine the prevalence of diabetes mellitus; data processing strategies should reflect the degree of problem orientation.

Meeting medical terminology needs--the Ontology-Enhanced Medical Concept Mapper.

This paper describes the development and testing of the Medical Concept Mapper, a tool designed to facilitate access to online medical information sources by providing users with appropriate medical search terms for their personal queries. Our system is valuable for patients whose knowledge of medical vocabularies is inadequate to find the desired information, and for medical experts who search for information outside their field of expertise. The Medical Concept Mapper maps synonyms and semantically related concepts to a user's query. The system is unique because it integrates our natural language processing tool, i.e., the Arizona (AZ) Noun Phraser, with human-created ontologies, the Unified Medical Language System (UMLS) and WordNet, and our computer generated Concept Space, into one system. Our unique contribution results from combining the UMLS Semantic Net with Concept Space in our deep semantic parsing (DSP) algorithm. This algorithm establishes a medical query context based on the UMLS Semantic Net, which allows Concept Space terms to be filtered so as to isolate related terms relevant to the query. We performed two user studies in which Medical Concept Mapper terms were compared against human experts' terms. We conclude that the AZ Noun Phraser is well suited to extract medical phrases from user queries, that WordNet is not well suited to provide strictly medical synonyms, that the UMLS Metathesaurus is well suited to provide medical synonyms, and that Concept Space is well suited to provide related medical terms, especially when these terms are limited by our DSP algorithm.

Liberation psychological implications for pastoral care of Korean military wives.

Native Korean women frequently suffer poverty, sexual violence, and Confucian gender discrimination. Once in America Korean military wives also experience racial and sexual oppression, intercultural familial conflicts and violence, and identity crisis and lead to feelings of isolation and non-belonging, a sense of anomie. Korean American pastors tend to understate and oversimplify the complexity of psychological and spiritual suffering of Korean military wives and overemphasize individual faith development as a solution. Liberation psychology evolved from an awareness of similar dehumanizing realities. The context-based perspective of liberation psychology offers a model to interpret and assist in the psychological and spiritual healing of Korean military wives. The healing power of conscientization offered in Liberation psychology for oppressed individuals encourages self-awakening suggesting it as an ideal interventional model to help Korean military wives and would be a useful approach for Korean American pastors.
