  3. Folding chair

    DOEpatents

    Cornell, Howell N.

    1985-08-20

    A foldable chair of the lawn chair type has ground-engaging front and rear legs, attached to and carrying a back frame and seat frame, the back frame and seat frame being pivotally attached to a spreader rod which extends beyond the back and seat frames to bear against one of the leg members when the chair is unfolded. A contact pad mounted on the extending portion of the spreader rod is formed as an externally-contoured bushing fit over the spreader rod and adapted to engage the leg member to restrict side-to-side movement of the spreader rod, with respect to the leg member, when the chair is unfolded.

  5. Ergonomic Chairs

    NASA Technical Reports Server (NTRS)

    1997-01-01

    Findings published in the NASA Anthropometric Source Book by Johnson Space Center helped BodyBilt, Inc. to fashion controlled comfort chairs that lessen the harmful effects of gravity on seated workers. Crew members living aboard NASA's Skylab noted that in space the human posture differs from the normal posture caused by the tug of one gravity. There has been an alarming increase in back pain and muscle fatigue in workers, along with a dramatic escalation in repetitive stress injuries. BodyBilt's ergonomically-correct line of office chairs are targeted for the average worker that sits for prolonged periods, be it in the classroom or boardroom. Their roster of national clients lists such organizations as IBM, Microsoft, Texas Instruments, Hewlett-Packard, Eastman-Kodak, Boeing, Motorola, and Walt Disney Studios.

  5. Rising from a chair. Influence of age and chair design.

    PubMed

    Wheeler, J; Woodward, C; Ucovich, R L; Perry, J; Walker, J M

    1985-01-01

    We studied the effect of age on the act of rising from a standard armchair in a younger (means = 24 years) and an older (means = 75 years) group of healthy adult women. Rising from a standard armchair and an armchair specially designed for comfort in sitting of the elderly was studied in the older group to determine the influence of the special chair. We used electrogoniometry, EMG, and videotape analysis to record the activity for both groups. The older group placed their feet farther back and showed greater vastus lateralis muscle activity than did the younger group to rise from the standard chair. These results suggest that rising from the standard chair was more difficult for the older than for the younger group. In the special chair, the older subjects showed even more vastus lateralis muscle activity, greater knee flexion, and greater trunk forward lean. Rising from the special chair, therefore, appeared to be more difficult than rising from a standard chair; this finding suggests that both comfort and function must be considered in chair selection for certain groups.

  6. An integrated water resources management strategy for Al-Ain City, United Arab Emirates

    NASA Astrophysics Data System (ADS)

    Mohamed, M. M.

    2014-09-01

    Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC) released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM), a Water Budget Model (WBM), and a Water Resources Optimization Model (WROM). The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

    2017-06-21

    As academic leaders, orthopaedic chairs represent role models for scholarly activities. Despite the importance of journal publications as a measure of scholarly activity, data on the publication productivity of orthopaedic chairs remain limited. The goals of this study were to record the publication productivity of orthopaedic chairs and evaluate the extent to which they maintained their scholarly activity while serving as chairs. The chairs of all orthopaedic residency programs in the United States were identified through the Accreditation Council for Graduate Medical Education (ACGME) web site, and were confirmed by information found on the web site of each orthopaedic program that was included in the study. University and non-university chairs were defined based on affiliation of the program with a medical school. The publication records of the program chairs were retrieved through the Scopus database. During the 7 years prior to their appointment to chair, the mean number of total publications was significantly higher for university chairs (n = 58.6, range 0 to 217) than for non-university chairs (n = 29.1, range 0 to 13) (p = 0.003). The mean number of publications per year during the 7 years leading up to the chair position was 4.66 (range, 0 to 25) for the university chairs, and 2.29 (range, 0 to 10.9) for the non-university group (p = 0.02). While serving as chair, the mean number of publications per year significantly decreased among the university chairs to 3.75 (range, 0 to 32.8; p = 0.015), whereas no significant change was observed among non-university chairs. The mean percentage of first authorships was not significantly different between university and non-university chairs. Both groups showed significant declines in first authorships while serving as chair. At the time of becoming chair, the average university chair had published approximately 60 manuscripts, whereas the average non-university chair had published approximately 30 manuscripts. While

  14. [Alain Georges: in the footsteps of Louis Pasteur and Eugène Jamot].

    PubMed

    Bélec, L; Milleliri, J M

    2014-01-01

    The biography of the physician general Alain Jean Georges (1946-2012) shows the exceptional career of a military physician-clinical pathologist specialized in tropical medicine and educated at the Navy Health School in Bordeaux and the Pharo School in Marseille. He completed his education at the Institut Pasteur de Paris in courses still conducted in the spirit of those taught by Louis Pasteur. In 1979, he became director of the Pasteur Institute of Bangui, following in the steps of Eugène Jamot, in the long tradition of military doctors from the Institut Pasteur overseas network committed to a career in Africa. For more than 12 years, Alain Georges directed the Pasteur Institute of Bangui, one of the last citadels of French postcolonial military medicine, in a very personal and charismatic style. He was thus a pioneer in research about both AIDS in Africa and hemorrhagic fevers. His methods were widely misunderstood later as the traditional networks of French biomedical research in its former African colonies modernized and opened internationally, including to national elites. Alain Georges was probably one of the last important figures of the golden age of French colonial medicine.

    2015-01-01

    We aimed to prospectively study the demography, severity of injury and outcome of alcohol-related road traffic collision (RTC) injuries in the United Arab Emirates. Data of RTC Registry of Al-Ain City were prospectively collected from Al-Ain and Tawam hospitals during the period of April 2006 to October 2007. It included all RTC trauma patients who were admitted or those who died after arrival to these hospitals. Car occupants with complete data on alcohol use were included in the study. Patients were divided into two groups, those who reported using alcohol and those who did not. Out of the 771 car occupants, sixteen (16) used alcohol (2.1%), 15 (94%) of them were males. The median (range) age of the alcohol group was significantly higher than those without alcohol (35 (15-53) years compared with 26 (1-78) years, p = 0.02). The UAE nationals were significantly more (P = 0.01) and the revised trauma score was significantly less in the alcohol group (P = 0.03). Head/face was the most commonly injured region in the alcohol group (94%). Self reported alcohol-related car collisions in Al-Ain City had a low incidence. It affected older Emirati male nationals and was associated with lower revised trauma score, mainly due to head injury. There is a need for a national registry with data on alcohol abuse so as to assess its effects and strategies for its prevention.

  2. Chair design and the anesthesia provider.

    PubMed

    Petty, W C

    1996-06-01

    Anesthesia providers spend a considerable amount of time sitting in poorly designed chairs. In the majority of hospitals, anesthesia providers are reluctant to request ergonomically designed chairs for the operating room. Multiple studies have given conclusive evidence that properly designed chairs reduce low back pain, improve lower extremity circulation, and relieve muscle tension, thus increasing overall comfort. Continual use of poorly designed chairs and stools in the operating room will cause eventual health complaints. Ergonomically designed chairs will be a wise purchase for the anesthesia provider, especially those who are aging or have physical complaints related to the back, muscle tension, and other lower extremity problems.

    2007-12-01

    A robotic chair is developed to support mobility of elderly and disabled people living in the house where steep and narrow stairways are installed. In order to deal with such mobility problem the developed robotic chair has a compact original configuration. The robotic chair vertically moves by actuation of electric cylinders and horizontally moves by push-pull operation given by a care-giver. In order to navigate safely every action of the chair is checked by the operator. Up-and-down motions of the robotic chair on the stairway are executed through combinations of motor and cylinder actuations. Performance of the robotic chair was evaluated through two kinds of experiments. The excellent ability of the robotic chair could be confirmed through these experiments.

    2016-01-01

    Although there is a considerable literature on transition of faculty members to the position of department chair, there is a dearth of publications about transitioning from the chair to other activities including retirement. The Association of Pathology Chairs senior fellows (all of whom are former chairs of academic departments of pathology) made this topic a focus of discussion at the Association of Pathology Chairs 2016 Annual Meeting. Of the 33 senior fellows engaged in this discussion, following their time as chairs, a small majority (18) transitioned to other administrative posts within or outside the university, while the others either returned to the active faculty (7) or retired (8). The motivating factors and influences for transitioning from the chair were probed along with the processes used in executing the transition, such as the development of transition plans. The reasons for selecting the specific type of postchair activity were also investigated. There was extraordinary diversity in the type of post-chair activities pursued. To our knowledge, no other medical specialty has examined these issues, which may be potentially relevant for the career planning of active chairs. PMID:28725780

  5. Chair-based fidgeting and energy expenditure

    PubMed Central

    Koepp, Gabriel A; Moore, Graham K; Levine, James A

    2016-01-01

    Introduction Sedentariness is associated with chronic health conditions, impaired cognitive function and obesity. Work contributes significantly to sedentariness because many work tasks necessitate sitting. Few sustained solutions exist to reverse workplace sedentariness. Here, we evaluated a chair and an under-table device that were designed to promote fidgeting while seated. Our hypothesis was that an under-table leg-fidget bar and/or a fidget-promoting chair significantly increased energy expenditure. We compared these devices with chair-based exercise and walking. Materials and methods We measured energy expenditure and heart rate in 16 people while they sat and worked using a standard chair, an under-desk device that encourages leg fidgeting and a fidget-promoting chair. We compared outcomes with chair-based exercise and walking. Results Energy expenditure increased significantly while using either an under-table leg-fidget bar or a fidget-promoting chair, when compared to the standard office chair (standard chair, 76±31 kcal/hour; leg-fidget bar, 98±42 kcal/hour (p<0.001); fidget chair, 89±40 kcal/hour (p=0.03)). However, heart rate did not increase significantly in either case. Bouts of exercise performed while seated provided energetic and heart rate equivalency to walking at 2 mph. Conclusions Chairs and devices that promote fidgeting can increase energy expenditure by ∼20–30% but not increase heart rate. Dynamic sitting may be among a lexicon of options to help people move more while at work. PMID:27900194

  6. Automated chair-training of rhesus macaques.

    PubMed

    Ponce, C R; Genecin, M P; Perez-Melara, G; Livingstone, M S

    2016-04-01

    Neuroscience research on non-human primates usually requires the animals to sit in a chair. To do this, typically monkeys are fitted with collars and trained to enter the chairs using either a pole, leash and jump cage. Animals may initially show resistance and risk injury. We have developed an automated chair-training method that minimizes restraints to ease the animals into their chairs. We developed a method to automatically train animals to enter a primate chair and stick out their heads for neckplate placement. To do this, we fitted the chairs with Arduino microcontrollers coupled to a water-reward system and touch- and proximity sensors. We found that the animals responded well to the chair, partially entering the chair within hours, sitting inside the chair within days and allowing us to manually introduce a door and neck plate, all within 14-21 sessions. Although each session could last many hours, automation meant that actual training person-hours could be as little as half an hour per day. The biggest advantage was that animals showed little resistance to entering the chair, compared to monkeys trained by leash pulling. This automated chair-training method can take longer than the standard collar-and-leash approach, but multiple macaques can be trained in parallel with fewer person-hours. It is also a promising method for animal-use refinement and in our case, it was the only effective training approach for an animal suffering from a behavioral pathology.

  7. Chair-based fidgeting and energy expenditure.

    PubMed

    Koepp, Gabriel A; Moore, Graham K; Levine, James A

    2016-01-01

    Sedentariness is associated with chronic health conditions, impaired cognitive function and obesity. Work contributes significantly to sedentariness because many work tasks necessitate sitting. Few sustained solutions exist to reverse workplace sedentariness. Here, we evaluated a chair and an under-table device that were designed to promote fidgeting while seated. Our hypothesis was that an under-table leg-fidget bar and/or a fidget-promoting chair significantly increased energy expenditure. We compared these devices with chair-based exercise and walking. We measured energy expenditure and heart rate in 16 people while they sat and worked using a standard chair, an under-desk device that encourages leg fidgeting and a fidget-promoting chair. We compared outcomes with chair-based exercise and walking. Energy expenditure increased significantly while using either an under-table leg-fidget bar or a fidget-promoting chair, when compared to the standard office chair (standard chair, 76±31 kcal/hour; leg-fidget bar, 98±42 kcal/hour (p<0.001); fidget chair, 89±40 kcal/hour (p=0.03)). However, heart rate did not increase significantly in either case. Bouts of exercise performed while seated provided energetic and heart rate equivalency to walking at 2 mph. Chairs and devices that promote fidgeting can increase energy expenditure by ∼20-30% but not increase heart rate. Dynamic sitting may be among a lexicon of options to help people move more while at work.

    Melville, Wayne; Campbell, Todd; Jones, Doug

    2017-08-01

    This article addresses two gaps in the literature related to science department chairs: the axiological relationship between the chair and science, the subject, and the perceptions of the chair with respect to teaching and learning within their departments. In this work, axiology is used to understand how the chair's values toward the subject influenced his own perceived capacity to lead learning within his department in a reformed discourse. A narrative inquiry methodology was used to consider the chair's experiences in the development of his identify over his life span in the form of two stories: (1) the relationship between the chair and science, the subject, and (2) the perceptions of the chair with regards to teacher learning within the department. The findings revealed that the work and career of the chair in this study were authored by strong elements of personal continuity and points of stability around the valuing of science, the subject, even as this valuing evolved from being more focused on epistemic values early in his career, to being more concerned with universal values connected to his legacy and his department later in his career.

    The prevalence of fear was explored in 340 adolescents in Al-Ain, United Arab Emirates. More than 50% reported feeling extremely frightened of 6 out of 60 fear items surveyed. These items were: someone dying in the family (66.5%), parents getting divorced (65.3%), the devil (63.8%), breaking a religious law (61.5%), being kidnapped (53.2%) and being adopted (49.9%). The level of fear showed a significant positive correlation with female gender, parental death/divorce, living with a single parent/relatives, living in low income families and an adverse home environment. Nearly half of the children reported that the fear caused considerable distress and interfered with daily activities.

  3. Chair Talk: Resources to Maximize Administrative Efforts

    MacDonald, H.; Chan, M. A.; Bierly, E. W.; Manduca, C. A.; Ormand, C. J.

    2009-12-01

    Earth science department chairs are generally scientists who have little/no formal administrative training. The common rotation of faculty members in three-six year cycles distributes the heavy leadership responsibilities but involves little preparation beforehand to deal with budgets, fundraising, personnel issues, confrontations, and crises. The amount of information exchange and support upon exit and handoff to the next chair is variable. Resources for chairs include workshops, meetings (ranging from annual meetings of geoscience chairs to monthly meetings of small groups of chairs from various disciplines on a campus), discussions, and online resources. These resources, some of which we designed in the past several years, provide information and support for chairs, help them share best practices, and reduce time spent “reinventing the wheel”. Most of these resources involve groups of chairs in our discipline who meet together. The AGU Board of Heads and Chairs of Earth and Space Science Departments offers annual one-day workshops at the Fall AGU meeting. The specific topics vary from year to year; they have included goals and roles of heads and chairs, fundraising and Advisory Boards, student recruitment, interdisciplinarity, dual-career couples, and undergraduate research. The workshop provides ample opportunities for open discussion. Annual one-two day meetings of groups of geoscience department chairs (e.g., research universities in a particular region) provide an opportunity for chairs to share specific data about their departments (e.g., salaries, graduate student stipends, information about facilities) and discuss strategies. At the College of William and Mary, a small group of chairs meets monthly throughout the year; each session includes time for open discussion as well as a more structured discussion on a particular topic (e.g., merit review, development and fundraising, mentoring early career faculty and the tenure process, leadership styles

  7. Secondary school science department chairs leading change

    NASA Astrophysics Data System (ADS)

    Gaubatz, Julie A.

    Secondary school department chairs are content area specialists in their schools and are responsible for providing students with the most appropriate curricula. However, most secondary school department chairs have limited authority to institute change unilaterally (Gmelch, 1993; Hannay & Erb, 1999). To explore how these educational leaders navigate the change process within their departments, this study examined the change stories of six secondary school science department chairs who had led change attempts. In total, these department chairs shared six stories of successful change attempts and four unsuccessful change attempts. The topics of leadership and change were accessed through department chair interviews, document analysis, and a leadership inventory. Department chair leadership was analyzed with Blake and McCanse's (1991) Leadership Grid, and further explored using Yukl, Gordon, and Taber's (2002) detailed characterization of this grid. The change processes described in these department chair stories were analyzed using the frameworks provided by Ely's (1990) conditions of change, and Havelock and Zlotolow (1995) CREATER change stages model. In general, the findings of this study support Havelock and Zlotolow's CREATER model, as well as Ely's conditions of change, with dissatisfaction with the status quo emerging as the essential condition for successful change. This study connects these change process frameworks to specific leadership strategies and behaviors, and uses these connections to illuminate differences between successful and unsuccessful instances of change. These findings, along with other unanticipated findings emerging from department chair stories of change, such as the adverse influence of contentious resistors and the importance of team construction, add both to the literature on change and leadership and to the crucial point where these concepts intersect.

    Proper positioning of the child patient, can not only have positive ramifications for the operator's posture, comfort, and career longevity - it can also lead to better treatment and increased productivity. The aim of the survey questionnaire was to assess the utilization, need, and attitude concerning dental chairs among pediatric dentist while working on and managing the child patient. The questions were structured using adobe forms central online software, regarding the user-friendliness of pediatric dental chair vs. traditional adult dental chair available in the market. Our result shows that out of 337 respondents, 79% worked on pediatric dental chair, whereas 21% had no experience of it. Of these 79% pediatric dentist, 48% preferred pediatric dental chair. But pediatric dental problem still has certain disadvantages like higher cost, leg space problem, lower availability, etc. During the research it was found that ergonomics and usability issues were the main problems. Thus, pediatric dental chair is not so popular in the current scenario. This study allowed for general ideas for the improvement of dental chairs and thus improved dental chair would fill the gap in the current scenario.

  17. Noise analysis in professional office chairs.

    Alves, E J W; Filho, J N; Silva, S J; Câmara, J J D

    2012-01-01

    The noise caused by the movement of users on their chairs in the work environment may indicate structural weaknesses and risk, and still significantly reduce productivity by increasing employees stress level. By understanding the activities to be developed in a work place one may understand what should be necessary to a good development, thereafter a search for improvement of labor activity with the aim of better use of resources in the operation of product use may be done. The analysis of the incremental variation of noise in professional chairs aims to identify its origin and the time the emission of noise starts during the period of use, its development and the major causative agents. Determining the characteristics of the sound of different materials and adjustments mechanisms of the chair can determine how different materials interact with each other. The measurement of these noises in an acoustic isolated room using directional microphones, if recorded and analyzed properly makes it possible to investigate and orientate to suspect elements in order to propose solutions and identify the quality of other similar chairs. Based on the results recommendations can be established for the orientation of users, managers and people responsible for the acquisition of the products, inducing them to review the employment of materials and the choice of the processes of production. These aspects are not covered in the Brazilian ergonomics norms and standards in the use of chairs.

    Shoulder arthroscopy has been shown to be the procedure of choice for many diagnostic and therapeutic interventions. Neuropraxia of the great auricular nerve (GAN) is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently.

    To identify common perceptions and ideas about preparation and planning for retirement of chairs of academic departments of ophthalmology, determining areas of particular stress and proposing ways to better prepare for retirement. Cross-sectional study. One-hundred sixteen chairs of academic departments of ophthalmology in the United States. A confidential online survey emailed to ophthalmology chairs. Surveys assessed demographics; current work schedule; perceptions, preparation, and planning for retirement; and retirement training for faculty and residents. Ninety-six department chairs responded to the survey (82% response rate). Most chairs anticipate retiring around age 70. Significantly, only 9% are looking forward to retirement. Reasons for delaying retirement include keeping active (37%), income/insurance/benefits (20%), and maintaining lifestyle (17%). The most common concern is financing retirement (46%). Forty percent anticipate their reason for retirement will be because of age or health, whereas 20% anticipate fatigue or burnout. Nearly half of the respondents have no specific plan upon retirement. Most respondents anticipate pursuing other interests (43%); 32% intend to spend time with family, vacationing, and travelling. Younger respondents are more concerned with the financial aspects of retirement while more senior respondents appear to delay retirement to keep active or because they enjoy their work. Retirement is a source of stress for many ophthalmology department chairs and many indicate financial preparation is their major concern. Despite this, the major reason for putting off retirement is a desire to keep active. Developing a retirement plan eases stress and engenders a feeling of confidence about the future.

    Physiological considerations suggest that the response of the vestibular system can be substantially modified during weightlessness and that such modifications affect susceptibility to motion sickness and to judgment of spatial localization. Evaluation of such effects requires measurement of responses to rotational accelerations before, during, and after exposure to conditions of prolonged zero-gravity. For this purpose, a precisely controlled rotating chair was designed, constructed, tested, and installed in the Skylab Orbital Workshop. The chair was used in three test modes to measure changes in the vestibular (balance) organs of the astronauts.

    The authors describe the current dilemma facing academic health centers (AHCs) as they recruit department chairs. In the past, leaders at AHCs predominantly were concerned with fulfilling the esteemed tripartite missions of patient care, research, and education. Today, their time and energy are occupied by a different set of tasks that have a distinct business orientation, including winning contracts, enhancing revenue, reducing costs, recruiting and managing a diverse workforce, and dealing with consumer satisfaction and marketing. New visions and strategies must be developed--requiring different dimensions of leadership. The authors offer concrete recommendations for recruiting, retaining, and sustaining department chairs, and argue that a deliberative, thoughtful process of engaging chair candidates should begin by focusing on the candidates' values as a first priority. Candidates who most clearly share organizational values should then be engaged in an iterative process of developing a shared vision, resulting in a letter of agreement that explicitly states the mutual expectations and commitments of both the organization and the candidate. Once department chairs are in place, ongoing development through leadership training, mentoring, and other investments help to retain and sustain them.

    Background/Study Context: The study estimates the reliability of peak velocity and peak power during chair rising and chair jumping tests and their ability to discriminate between different age and physical activity level groups. Physically active and sedentary individuals (N = 262) of different ages (young: 22.9 ± 2.0 years, range: 21-25 years; older: 63.1 ± 1.8 years, range: 61-65 years) performed, in random order, chair rising and chair jumping tests on a force plate. Randomly selected young subjects performed both tests repeatedly on two different occasions separated by 1 week. From the sitting position with the arms crossed on the chest, they either stand up completely (chair rising test), or jump as high as possible (chair jumping test). The test-retest reliability of peak power and peak velocity during chair rising as well as chair jumping was excellent, with high intraclass correlation coefficients (ICCs; .90-.98) and low standard error of measurement (SEM; 7.0-9.1%). Post hoc analysis revealed significant differences in peak power and peak velocity between the sedentary and physically active young and older subjects. However, greater coefficients of variation for both parameters were found for chair jumping than chair rising (21.1-40.2% vs. 11.0-15.2%). Additionaly, there were moderate correlations of peak power and peak velocity between chair rising and chair jumping (r = .42-.49). There were greater within- and between-group differences in peak force and peak power and a steeper increase in their values during the initial phase of chair jumping than chair rising. Both chair rising and chair jumping tests provide reliable data and are valid indicators of lower body power in young and older adults. However, jumping from a chair is a more sensitive measure of strength and power performance than chair rising.

    2015-01-01

    This paper examines how the individual variations of chair type, row spacing, as well as the presence of occupants and carpet, combine to influence the absorption characteristics of theater chairs as a function of sample perimeter-to-area (P/A) ratios. Scale models were used to measure the interactive effects of the four test variables on the chair absorption characteristics, avoiding the practical difficulties of full scale measurements. All of the test variables led to effects that could lead to important changes to auditorium acoustics conditions. At mid and higher frequencies, the various effects can usually be explained as due to, more or less, porous absorbing material. In the 125 and 250 Hz octave bands, the major changes were attributed to resonant absorbing mechanisms. The results indicate that for accurate predictions of the effective absorption of the chairs in an auditorium, one should use the P/A method and reverberation chamber tests of the chair absorption coefficients to predict the absorption coefficients of each block of chairs and use these results as input in a room acoustics computer model of the auditorium. The application of these results to auditorium acoustics design is described, more approximate approaches are considered, and relations to existing methods are discussed.

  13. A living model of managed competition: a conversation with Dutch health minister Ab Klink. Interview by Alain Enthoven.

    2008-01-01

    As of 2006, the Netherlands requires all citizens to buy a standard package of health benefits from private insurers. The government subsidizes premiums for those with low incomes and requires insurers to accept all purchasers. This mixed private-public approach to universal coverage has emerged as a potential reform model for the United States. In this November 2007 interview, Dutch health minister Ab Klink discussed his country's system with Alain Enthoven. Enthoven is one of the chief architects of the "managed competition" model that laid the groundwork for the Clinton administration reform proposal in the 1990s and pending legislation in the Senate, as well as the current Dutch approach.

    2017-10-01

    Dynamic sitting approaches have been advocated to increase seated energy expenditure with the view of lessening the sedentary nature of the task. This study compared energy expenditure (EE) and overall body discomfort on a novel dynamic chair with a standard office chair. Fifteen pain-free participants completed a DVD viewing task on both chairs in a randomised order. Energy expenditure and discomfort were collected simultaneously. Linear mixed models were used to analyse steady-state EE recorded on each of the chairs. Differences in discomfort were analysed using Wilkoxon Signed Rank Tests. Sitting on the novel dynamic chair significantly (p = 0.005) increased energy expenditure compared to a standard office chair. The discomfort experienced was mild overall, but was significantly greater on the dynamic chair (p = 0.004). Whilst the EE was seen to be significantly higher on the dynamic chair, the MET values are still below 1.5 METS. Thus, the use of a dynamic chair does not seem to be the most effective measure to prevent sedentary behaviour. Practitioner Summary: Sitting on a dynamic chair increased energy expenditure compared to sitting on a standard office chair among pain-free participants. Whilst the EE was seen to be significantly higher on the dynamic chair, the MET values are still below 1.5 METS (low level EE).

  8. "Rocking-Chair"-Type Metal Hybrid Supercapacitors.

    Hybrid supercapacitors that follow a "rocking-chair"-type mechanism were developed by coupling divalent metal and activated carbon electrodes in nonaqueous electrolytes. Conventional supercapacitors require a large amount of electrolyte to provide a sufficient quantity of ions to the electrodes, due to their Daniell-type mechanism that depletes the ions from the electrolyte while charging. The alternative "rocking-chair"-type mechanism effectively enhances the energy density of supercapacitors by minimizing the necessary amount of electrolyte, because the ion is replenished from the metal anode while it is adsorbed to the cathode. Newly developed nonaqueous electrolytes for Mg and Zn electrochemistry, based on bis(trifluoromethylsulfonyl)imide (TFSI) salts, made the metal hybrid supercapacitors possible by enabling reversible deposition on the metal anodes and reversible adsorption on an activated carbon cathode. Factoring in gains through the cell design, the energy density of the metal hybrid supercapacitors is projected to be a factor of 7 higher than conventional devices thanks to both the "rocking-chair"-type mechanism that minimizes total electrolyte volume and the use of metal anodes, which have substantial merits in capacity and voltage. Self-discharge was also substantially alleviated compared to conventional supercapacitors. This concept offers a route to build supercapacitors that meet dual criteria of power and energy densities with a simple cell design.

    There is a growing demand that severely disabled children should be offered a normal-looking, comfortable alternative to highly supportive wheelchair seating to facilitate relaxation and social integration. An evaluation of five chairs, funded by Medical Devices Agency, an executive agency of the Department of Health, was undertaken with potential and actual users of these chairs to investigate the chairs' function with respect to the child's posture, and what features were effective. Twenty-nine children tried five chairs for up to 30 min in each; and a postal survey received 100 responses. The chairs seem to meet many users' postural needs (78% of postal survey; 31-72% of short-term evaluation depending on chair); the chairs' adjustability and availability of special features are important in meeting the needs of this user group; evidence of poor design and its implications are discussed.

    Office chairs have often been designed to promote a single 'correct' rather rigid and upright posture, yet it is acknowledged that allowing changes in posture is good ergonomics practice. The present study investigated office worker's preferences for a standard shaped typist's chair (ST) and a prototype multi-posture (PMP) office chair designed to allow its users a variety of sitting positions. Forty-two (22 male and 20 female) telesales personnel (12), clerical staff (12) and researchers (18) used ST or PMP in their workplace for the first week of a 2-week study (with an even number in each work area). The PMP chair was introduced to participants with a brief lecture on how to use it and with an information booklet. Following this, each participant completed a chair comfort questionnaire. In the second week, participants swapped chairs and again completed the chair comfort questionnaire. At the end of the second week participants were also asked to complete a separate questionnaire about the usability of the information booklet that accompanied the PMP chair. Statistically significant differences in subject's rating of the two chairs were observed in 7 out of 19 questions. On a 100 mm scale, the ST chair was rated as having a greater mean overall acceptability, desirability and suitability for body build than the PMP chair. Participants also claimed to achieve better posture in the ST chair, that they tipped forward less and were more satisfied with its width. Although the participants generally preferred the ST chair, the PMP chair received more favourable ratings among the researchers who were quite mobile in their work, and in whom there was a trend for less neck, shoulder and upper back discomfort. More participants reported an overall preference for the PMP chair. The findings suggest that a more aesthetically acceptable PMP chair should be developed, peoples' reasons for preferring a more traditionally designed chair should be explored, and that the effect

    Prolonged and static sitting postures provoke physical inactivity at VDU workplaces and are therefore discussed as risk factors for the musculoskeletal system. Manufacturers have designed specific dynamic office chairs featuring structural elements which promote dynamic sitting and therefore physical activity. The aim of the present study was to evaluate the effects of four specific dynamic chairs on erector spinae and trapezius EMG, postures/joint angles and physical activity intensity (PAI) compared to those of a conventional standard office chair. All chairs were fitted with sensors for measurement of the chair parameters (backrest inclination, forward and sideward seat pan inclination), and tested in the laboratory by 10 subjects performing 7 standardized office tasks and by another 12 subjects in the field during their normal office work. Muscle activation revealed no significant differences between the specific dynamic chairs and the reference chair. Analysis of postures/joint angles and PAI revealed only a few differences between the chairs, whereas the tasks performed strongly affected the measured muscle activation, postures and kinematics. The characteristic dynamic elements of each specific chair yielded significant differences in the measured chair parameters, but these characteristics did not appear to affect the sitting dynamics of the subjects performing their office tasks.

    2010-01-01

    Chair rise performance, which is simple to assess in a home or clinic setting, has been used as a method of predicting leg power deficit in older adults. More recently, chair rise performance has been assessed in younger populations as a baseline for assessment of subsequent age-related declines in function and power. However, as rising from a chair repeatedly not only requires lower limb strength and power but also good balance and coordination, it may not be purely a measure of leg power especially among these younger, well functioning groups who are yet to experience agerelated declines and deficits in function. The aim of this study was to assess whether chair rise performance can be considered as a predictor of leg power, and hence of deficits in this, in men and women in mid-life. We assessed the relationship of chair rise performance with leg extensor power (LEP), measured using the Nottingham Power Rig (NPR), and with standing balance performance. LEP was measured in a clinic setting in a sub-sample of 81 men and 93 women from the MRC National Survey of Health and Development, a nationally representative cohort born in Britain in 1946. The time taken to rise from a chair 10 times and standing balance time were assessed during home visits at the same age. Increasing LEP was associated with better chair rise performance among those who completed 10 chair rises in ≥15 seconds, after adjustment for body size (p=0.008). Better standing balance performance was associated with better chair rise performance in men, but not women. That LEP and standing balance are both related to chair rise time in men suggests that chair rise time should not be thought of purely as a proxy measure of leg power in middle-aged populations. This has implications for longitudinal studies which want to study age-related decline in chair rise performance.

    To investigate the severity of and contributing factors of early childhood caries (ECC) in preschool children presented to a paediatric dentistry department in Al-Ain Dental Centre, United Arab Emirates; to study the level of any previous dental care provided to these children and to establish a baseline database for further research and the resources required for serving preschool children in Al-Ain (UAE). Cross-sectional prospective. The sample consisted of all healthy children below 5 years of age who presented for their initial visits to the Department of Paediatric Dentistry during a 3-month period. A structured questionnaire was used to obtain information regarding demographic data, feeding history and dietary habits, and oral hygiene practices. The dental examination of children was conducted by the investigator with the help of a mouth mirror and Sirona dental unit light source. One hundred and seventy six children with a mean age of 3.7 years were included in the study and 78 (44 %) children were still bottle-fed on demand at the time of examination. More than half of the children consumed sweets more than once/day and 58 % either never or rarely brushed their teeth. Only one child was given fluoride. Two-thirds of children had never visited a dentist before and 63 % had poor oral hygiene. The mean dmft and dmfs scores were 10.9 and 32.1, respectively. The care index was very low (6.4 %). The high level of dental decay could be attributed to on-demand bottle feeding, high sweet consumption, poor oral hygiene, lack of use of fluoride prevention and lack of regular dental visits. There is a great need for prospective studies and community preventive programmes to solve the continuing problem of ECC.

    2016-01-01

    Although there is a considerable literature on transition of faculty members to the position of department chair, there is a dearth of publications about transitioning from the chair to other activities including retirement. The Association of Pathology Chairs senior fellows (all of whom are former chairs of academic departments of pathology) made this topic a focus of discussion at the Association of Pathology Chairs 2016 Annual Meeting. Of the 33 senior fellows engaged in this discussion, following their time as chairs, a small majority (18) transitioned to other administrative posts within or outside the university, while the others either returned to the active faculty (7) or retired (8). The motivating factors and influences for transitioning from the chair were probed along with the processes used in executing the transition, such as the development of transition plans. The reasons for selecting the specific type of postchair activity were also investigated. There was extraordinary diversity in the type of post-chair activities pursued. To our knowledge, no other medical specialty has examined these issues, which may be potentially relevant for the career planning of active chairs.

  1. Chair of a department of medicine: now a different job.

    PubMed

    Kastor, John A

    2013-07-01

    The job of chair of a department of medicine, once seen as the apex in the career of an academic internist, has lost much of its allure, in part because of increasing administrative and financial obligations that require more of the time and effort of chairs than formerly. This is the impression the author gathered from interviewing 44 current and former chairs, deans, division chiefs, and hospital directors.He was told that chairs have lost some of their independence as departments have become increasingly dependent on the support of the executives at their university hospitals who, as the source of funds and facilities, can even specify which clinical services the chairs may develop. Conflict over the assignment of resources between dean and hospital CEO, which one interviewee stated can produce "incredible tensions," can complicate efforts of chairs to build clinical and research strength within their departments according to their own preferences. The growing administrative and financial duties of the job have forced some chairs to decrease their dedication to the classic responsibilities of teaching medical students and house officers.Recruiting outstanding leaders for departments of medicine challenges search committees and deans more than in the past because many suitable candidates do not choose to be considered and prefer to lead institutes, centers, or specialty divisions. The author suggests, however, that schools-by providing chairs with adequate administrative support and authority-can structure the job to improve its attractiveness and allow chairs more time to engage in traditional academic pursuits.

    Abstract Background Concurrent with the evolving role of the department chair in academic medicine is the entry of women physicians into chair positions. Because implicit biases that stereotypically masculine behaviors are required for effective leadership remain strong, examining faculty members' perceptions of their chair's leadership in medical school departments with women chairs can provide insight into the views of women leaders in academic medicine and the complex ways in which gender may impact these chairs' leadership style and actions. Methods We conducted semistructured interviews with 13 male and 15 female faculty members representing all faculty tracks in three clinical departments chaired by women. Inductive, qualitative analysis of the subsequent text allowed themes to emerge across interviews. Results Four themes emerged regarding departmental leadership. One dealt with the leadership of the previous chair. The other three described the current chair's characteristics (tough, direct, and transparent), her use of communal actions to help support and mentor her faculty, and her ability to build power through consensus. Because all three chairs were early in their tenure, a wait and see attitude was frequently expressed. Faculty generally viewed having a woman chair as an indication of positive change, with potential individual and institutional advantages. Conclusions This exploratory study suggests that the culture of academic medicine has moved beyond questioning women physicians' competence to lead once they are in top organizational leadership positions. The findings are also consonant with experimental research indicating that women leaders are most successful when they pair stereotypic male (agentic) behaviors with stereotypic female (communal) behaviors. All three chairs exhibited features of a transformational leadership style and characteristics deemed essential for effective leadership in academic medicine. PMID:20156081

  18. The Strategic Value of Succession Planning for Department Chairs.

    PubMed

    Rayburn, William; Grigsby, Kevin; Brubaker, Linda

    2016-04-01

    Most faculty who aspire to be department chairs are unaware of succession processes at their institution. This Commentary highlights the importance of succession planning, emphasizing the general need for transparency. Succession planning provides institutional leaders the opportunity to optimize, renew, and revitalize their organization by ensuring successful leadership transitions. In contrast to leadership pathways in the military, corporate business, and hospital administration, planned succession of medical school department chairs has received little attention. Different approaches to succession planning are essential for emergency and planned transitions. Emergency succession plans should be in place at all times, regularly revisited, and modified as needed. Department chairs should begin considering their planned succession between one and five years after their initial appointment. The succession discussion between a chair and medical school dean requires cautious, thoughtful, and open discussions. Intradepartmental annual faculty performance evaluations permit the chair to mentor potential successors in acquiring future-oriented, institution-based leadership qualities necessary to be considered for a future department chair position. If health and time permit, the successful chair should remain in his or her current position until a successor is named or, preferably, is in place. Appointment of an interim chair as part of succession planning can be useful for on-the-job training of an internal candidate, yet awkwardness might ensue if there is more than one internal candidate.Succession development offers the great advantage of maintaining smooth organizational performance while optimizing talent management and exploring opportunities for transitioning individuals into leadership roles.

    [Purpose] This study was designed to test the effects of the Assistant Chair-Desk System (ACDS), which can reduce the forward tilt of the neck and trunk and the level of fatigue during long lasting study in the sitting position. [Subjects] Fourteen middle school students and 14 college students of mixed gender participated in this study. [Methods] Fatigue level, the trapezius muscle, and the forward tilt angle of the head and trunk as well as distance factors were assessed before after using a normal chair-desk system (NCDS) and the ACDS for 120 minutes. [Results] There was an interaction effect in the angle and length of the neck from the sitting posture changes after 2 hours of studying using the NCDS and ACDS. There were also significant differences in the fatigue levels, hip joint angles and the lengths from the head according to the main effects of the chair-systems. [Conclusion] The studying position while using the ACDS was determined to prevent significant fatigue levels of the muscle and body, provide support to the head, by limiting the forward movement of the neck, and prevent forward tilt of the neck and trunk, by enabling the target point and gaze to be closer to the horizontal direction.

  3. Changing chairs: anticipating problems in prescribing wheelchairs.

    PubMed

    Batavia, M; Batavia, A I; Friedman, R

    2001-08-15

    This article presents a framework for prescribing, ordering, and adapting a new wheelchair, focusing on individual, environmental and wheelchair factors that must be taken into consideration to ensure optimal function. A review and analysis was conducted of all factors relevant to the transition to a new wheelchair. Without appropriate planning and implementation, this transition can result in unnecessary expenses, duplication of effort, and possibly even injury to the user and abandonment of the wheelchair. Recommendations are provided to manufacturers, therapists, technicians, users, insurers and physicians, who must work together throughout this process. To the extent feasible, the authors suggest that major changes from the previous wheelchair should be avoided, particularly for people with substantial functional limitations. Therapists and technicians must measure the user accurately, and anticipate those factors that can impede a smooth transition. Insurers and other payors must recognize that changing wheelchairs will often require substantial professional assistance, including several fittings to adjust the new chair to the needs of the user. Additional research and case reporting on outcomes of adjusting to a new wheelchair appear warranted.

    The aims of this study were to determine the self-reported prevalence of burnout in chairs of academic radiation oncology departments, to identify factors contributing to burnout, and to compare the prevalence of burnout with that seen in other academic chair groups. An anonymous online survey was administered to the membership of the Society of Chairs of Academic Radiation Oncology Programs (SCAROP). Burnout was measured with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Questionnaires were returned from 66 of 87 chairs (76% response rate). Seventy-nine percent of respondents reported satisfaction with their current positions. Common major stressors were budget deficits and human resource issues. One-quarter of chairs reported that it was at least moderately likely that they would step down in the next 1 to 2 years; these individuals demonstrated significantly higher emotional exhaustion. Twenty-five percent of respondents met the MBI-HSS criteria for low burnout, 75% for moderate burnout, and none for high burnout. Group MBI-HSS subscale scores demonstrated a pattern of moderate emotional exhaustion, low depersonalization, and moderate personal accomplishment, comparing favorably with other specialties. This is the first study of burnout in radiation oncology chairs with a high response rate and using a validated psychometric tool. Radiation oncology chairs share similar major stressors to other chair groups, but they demonstrate relatively high job satisfaction and lower burnout. Emotional exhaustion may contribute to the anticipated turnover in coming years. Further efforts addressing individual and institutional factors associated with burnout may improve the relationship with work of chairs and other department members. Copyright © 2014 Elsevier Inc.

    2011-01-01

    The authors examine the tenure of first-time Chairs in academic departments of psychiatry in order to stimulate discussion on extant workforce and leadership issues. Data on tenure of Chairs in psychiatry and other nonsurgical specialties were derived from the longitudinal database of the Association of American Medical Colleges and evaluated for successive 4-year epochs between 1983 and 2002. The 5-year retention rate of Chairs of academic departments of psychiatry is 68%, and the 10-year retention rate drops sharply to 39%, similar to other specialties. Although most first-time Chairs of psychiatry last 5 years in their position, much fewer remain 10 years or longer. Therefore, efforts to promote succession planning for academic leadership in psychiatry are warranted. Copyright © 2011 Academic Psychiatry

  2. Influence of Chair Vibrations on Indoor Sonic Boom Annoyance

    Rathsam, Jonathan; Klos, Jacob; Loubeau, Alexandra

    2015-01-01

    One goal of NASA’s Commercial Supersonic Technology Project is to identify candidate noise metrics suitable for regulating quiet sonic boom aircraft. A suitable metric must consider the short duration and pronounced low frequency content of sonic booms. For indoor listeners, rattle and creaking sounds and floor and chair vibrations may also be important. The current study examined the effect of such vibrations on the annoyance of test subjects seated indoors. The study involved two chairs exposed to nearly identical acoustic levels: one placed directly on the floor, and the other isolated from floor vibrations by pneumatic elastomeric mounts. All subjects experienced both chairs, sitting in one chair for the first half of the experiment and the other chair for the remaining half. Each half of the experiment consisted of 80 impulsive noises played at the exterior of the sonic boom simulator. When all annoyance ratings were analyzed together there appeared to be no difference in mean annoyance with isolation condition. When the apparent effect of transfer bias was removed, a subtle but measurable effect of vibration on annoyance was identified.

  3. The microbiological quality of water in dental chair units.

    Pankhurst, C L; Philpott-Howard, J N

    1993-03-01

    Infection control is an important issue in the dental surgery but the potential hazards associated with contaminated dental water have received relatively little attention in recent years. The complex design of the equipment results in stagnation of water within the dental chair and subsequent amplification of contaminating environmental organisms, including pseudomonads and legionellae, to potentially hazardous levels. Immunocompromised patients may be at particular risk of infection. Very poor water quality with total bacterial counts above 10(4) ml-1 is unpleasant for all patients, and the dental chair supply should be of drinking water quality. In addition to these problems, bacteria and viruses may be aspirated from the oral cavity and contaminate the handpiece. Measures to reduce microbial contamination of dental chairs and equipment include flushing water through the chair's equipment at the beginning of each day; continuous or pulsed water chlorination, or application of biocides other than chlorine; provision of sterile bottled water in the system; and autoclaving handpieces between patients. Future dental chair design must attempt to resolve the problems associated with microbial contamination of the water supply and aerosols generated during dental procedures.

Dimensions of school chairs were compared with three anthropometric variables of the pupils. Descriptive statistics were analysed for all variables. These study results have shown that furniture of appropriate dimensions is not available to a large number of students in Croatia. Currently supplied classroom equipment is provided in only two sizes and does not fit the users. It is recommended that task chairs may be acceptable if they are issued in four heights or individually adjustable chairs be introduced in Croatian schools. Furthermore it is strongly recommended that schools actively promote appropriate active sitting behaviour.

  6. The influence of chair seat height on the performance of community-dwelling older adults' 30-second chair stand test.

    2013-06-01

    Although chair seat height affects the performance of sit-to-stand movement, no previous study has examined the influence of chair seat height on the 30-second chair stand test (CST). Fifty-five community-dwelling older adults (age 70.0 ± 6.3 years) performed the test from the standard height of 43 cm and then from five randomly ordered seat heights from 80 to 120 % of each participant's lower leg length. Chair seat height significantly influences the performance of community-dwelling older adults' 30-s CST (F = 57.50, p < 0.001). The mean score for standard conditions was significantly lower from those at 120, 110, and 100 % conditions (p < 0.05). No significant difference was observed between the standard and 80 % conditions (p > 0.95) and between the standard and 90 % conditions (p = 0.353). When comparing the scores between the randomly ordered chair seat heights, all comparisons were significantly different (p < 0.001) except for the difference between the 120 and 110 % conditions (p = 0.104). Chair seat height's relation to the lower leg length should be considered when interpreting 30-s CST scores. Additionally, it is necessary to optimize the chair seat height when using the 30-s CST as an outcome measure for exercise intervention or to screen for people with weaker lower extremities.

  7. Does a prototype 'Experimental' chair facilitate more postural changes in computing adolescents compared to a normal school chair?

    Prolonged sitting, such as when computing, has been linked to adolescent spinal pain. A chair should fit the user's body dimensions and aid the user in frequently changing sitting posture, rather than support one 'ideal' posture. Such a chair is not currently available to high school learners. To develop a novel experimental school chair. To determine whether the experimental chair encourages regular small range movement in all directions whilst students work at computers in class. To compare the number of postural changes between the normal static school chair and the experimental chair, whilst students do computing work. A development and validation study was conducted. Twelve high school students were randomly selected from a conveniently selected school. Fifteen minutes of 3D posture measurements were collected in both the prototype and school computer chair. The analysis focused on the frequency of postural movement. Data of eleven learners were analysed. There were statistically significant increases in the number of postural changes on the 'Experimental' chair compared to the school chair, for both pelvic side-flexion and pelvic rotation (ρ= 0.01). The experimental chair provided more postural movements when compared to the school computer chair. Future studies should use this experimental chair to determine the effect of increased postural movement, of especially the pelvis, on the prevalence and intensity of musculoskeletal symptoms of high school learners in the Cape Metropole area, Western Cape, South Africa.

  8. A New Version of the Beuchet Chair Illusion.

    PubMed

    Wiseman, Richard

    2016-01-01

    The Beuchet Chair is a powerful and highly popular optical illusion. The illusion involves two reasonably large pieces of apparatus: an oversized chair seat and four normal-sized chair legs. When properly arranged and viewed from a precise location, a person standing on the seat appears to be much smaller than they actually are. Although compelling, the illusion is relatively challenging and expensive to construct, requires a large amount of space to stage, and is not especially portable. Here, I outline a new version of the illusion that just involves a small piece of cardboard, a cloth, and a tripod. This new version costs almost nothing to create, is highly portable, and requires far less space than the original.

    Objectives: To implement a prospective interventional clinical audit to evaluate the current clinical practice and the effect of standard interventions on the management of type 2 diabetes (T2DM). Methods: 254 patients with T2DM where recruited in a specialized diabetes care center in Al-Ain, UAE. The diabetes care components were audited before (baseline) and after (3 and 6 months) implementation of Institute of Clinical System Improvement (ICSI) guidelines. Data was compared against international guidelines to achieve target goals of normoglycemia, blood pressure (BP), and low density lipoprotein-cholesterol (LDL-C). We measured changes in mean scores of patient satisfaction level regarding diabetes care at similar intervals, by validated Patient Satisfaction Questionnaire (PSQ-18). Results: We observed a significant reduction in fasting blood glucose (FBG; mean± SD; 9.3 ± 0.03 vs 7.4 ± 0.3mmol/l; P=0.03), and HbA1c (8.7 ± 0.02 vs 8.1 ± 0.02 %; P=0.04) levels after 6 months compared with baseline. Patients who achieved target FBG and HbA1c levels improved significantly (45.7 vs 81.1%; P=0.03), and (40.1 vs 73.6%; P=0.04), respectively. The LDL-C levels improved, though this was not statistically significant. Patients achieving target of BP control improved significantly (SBP 142±7.6 and DBP 95±6.2 vs SBP 136±8.2 and DBP 87±5.8 mmHg;P=0.05). Conclusions: The results of this interventional audit were generally positive and emphasized the feasibility of improving the current clinical practice. Our individualized approach has helped us to achieve a better target in glycemic and BP control as well as patient satisfaction. Further research is needed to understand the long-term impact of our structured approach to improve the quality of T2DM care in the UAE. PMID:23136620

    Gregory Jaczko, chair of the U.S. Nuclear Regulatory Commission (NRC), announced on 21 May that he will resign once his successor is appointed. His resignation will end a stormy 3-year chairmanship during which he was accused of bullying NRC staff, lying to Congress, and being too close to the political process. Jaczko formerly served as science advisor to Sen. Harry Reid (D-Nev.). As NRC chair, Jaczko halted the commission's license application review for storing nuclear waste at Nevada's Yucca Mountain. In addition, during his NRC tenure the commission focused on identifying and implementing lessons from Japan's Fukushima Daiichi reactors damaged by the 2011 tsunami.

    Patients with neurogenic orthostatic hypotension may use portable folding chairs to prevent or reduce symptoms of low blood pressure. However, a concomitant movement disorder may limit the use of these chairs in daily living. In this prospective study, 13 patients with orthostatic hypotension, balance disturbance associated with motor disability, or both examined three commercially available portable folding chairs. A questionnaire was used to document the characteristics in chair design that were relevant for satisfactory use to these patients. Armrests, seat width, and an adjustable sitting height were found to be important features of a portable folding chair. One chair was selected by 11 of 13 patients to fit most needs.

    2014-01-01

    To advance care for patients and families requires that providers and administrators in clinical settings place a high priority on the scientific domain of nursing. New knowledge intended to benefit nursing care is most effectively and efficiently achieved when a vibrant and well-supported nursing research program is embedded within a health care system. An endowed chair in nursing research is an esteemed strategy acknowledging the contributions of nursing science, providing credibility to a researcher and research programs, and demonstrating commitment to the infrastructure for nursing research. Organizational readiness through leadership; systems thinking; relationship development; and knowledge of the dynamics, process, and expectations of philanthropy are essential to establishing an endowed chair. Philanthropic endeavors can be used to strategically develop a high-impact campaign that resonates across public and private sectors to secure funding to solidify and advance nursing research. By actively engaging stakeholders including system leaders, frontline nurses, and other care providers and development leaders, a successful campaign can establish and sustain an endowed chair in nursing research. This article describes the stakeholders, processes, structure, and outcomes for the first endowed chair in nursing research at Children's National Health System in Washington, DC.

  20. The analytic setting today: using the couch or the chair?

    PubMed

    Wiener, Jan

    2015-09-01

    This paper re-visits Murray Jackson's 1961 paper in the Journal of Analytical Psychology, 'Chair, couch and countertransference', with the aim of exploring the role of the couch for Jungian analysts in clinical practice today. Within the Society of Analytical Psychology (SAP) and some other London-based societies, there has been an evolution of practice from face-to-face sessions with the patient in the chair, as was Jung's preference, to a mode of practice where patients use the couch with the analyst sitting to the side rather than behind, as has been the tradition in psychoanalysis. Fordham was the founding member of the SAP and it was because of his liaison with psychoanalysis and psychoanalysts that this cultural shift came about. Using clinical examples, the author explores the couch/chair question in terms of her own practice and the internal setting as a structure in her mind. With reference to Bleger's (2013) paper 'Psychoanalysis of the psychoanalytic setting', the author discusses how the analytic setting, including use of the couch or the chair, can act as a silent container for the most primitive aspects of the patient's psyche which will only emerge in analysis when the setting changes or is breached. © 2015, The Society of Analytical Psychology.

    The 13 Human Research Program (HRP) Standing Review Panel (SRP) Chairs, and in some cases one or two additional panel members (see section XIV, roster) referred to as the Chair (+1) SRP throughout this document, met at the NASA Johnson Space Center (JSC) on December 7, 2010 to allow the HRP Elements and Projects to report on their progress over the past year, their current status, and their plans for the upcoming year based on NASA's current goals and objectives for human space exploration. A large focus of the meeting was also used to discuss integration across the HRP scientific disciplines based on a recommendation from the 2009 HRP SRP review. During the one-day meeting, each of the HRP Elements and Projects presented the changes they made to the HRP Integrated Research Plan (IRP Rev. B) over the last year, and what their top three areas of integration are between other HRP Elements/Projects. The Chair (+1) SRP spent sufficient time addressing the panel charge, either as a group or in a separate closed session, and the Chair (+1) SRP and the HRP presenters and observers, in most cases, had sufficient time to discuss during and after the presentations. The SRP made a final debriefing to the HRP Program Scientist, Dr. John B. Charles, prior to the close of the meeting on December 7, 2010. Overall, the Chair (+1) SRP concluded that most of the HRP Elements/Projects did a commendable job during the past year in addressing integration across the HRP scientific disciplines with the available resources. The Chair (+1) SRP agreed that the idea of integration between HRP Elements/Projects is noble, but believes all parties involved should have the same definition of integration, in order to be successful. The Chair (+1) SRP also believes that a key to successful integration is communication among the HRP Elements/Projects which may present a challenge. The Chair (+1) SRP recommends that the HRP have a workshop on program integration (with HRP Element

  4. Emotional Intelligence and Burnout in Academic Radiation Oncology Chairs.

    Holliday, Emma B; Bonner, James A; Formenti, Silvia C; Hahn, Stephen M; Kalnicki, Shalom; Liu, Fei-Fei; Movsas, Benjamin; Fuller, Clifton D; Thomas, Charles R

    The importance of emotional intelligence (EI) in physicians has attracted attention as researchers begin to focus on the relationship of EI to retention, promotion, and productivity among academic physicians. However, to date, no formal evaluation of EI has been conducted among current department chairs. The objectives of this study were to assess the EI of current chairs of academic radiation oncology departments and to correlate EI with a self-reported assessment of burnout.The authors invited 95 chairs of academic radiation oncology departments to participate in a survey, approved by an institutional review board, consisting of the Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF) and the abbreviated Maslach Burnout Inventory (a-MBI). TEIQue-SF scores were evaluated for correlation with respondents' demographics and self-reported burnout scores on the a-MBI. Sixty chairs responded to the survey, for a response rate of 63.2%. The median (interquartile range) TEIQue-SF for the responding cohort was 172 (155-182) out of a maximum possible score of 210. The a-MBI emotional exhaustion and depersonalization subscores were low, with median (interquartile range) scores of 4 (2.25-6.75) and 1 (0-2.75) out of maximum possible scores of 18 and 30, respectively. Higher TEIQue-SF global scores were weakly correlated with decreased burnout. The study results show that academic radiation oncology chairs had a high EI and low rates of self-reported burnout. EI may be of increasing importance with respect to recruitment and retention of academic medical leaders.

    Dynamic chairs have the potential to facilitate movements that could counteract health problems associated with sedentary office work. This study aimed to evaluate whether a dynamic chair can increase movements during desk-based office work. Fifteen healthy subjects performed desk-based office work using a dynamic office chair and compared to three other conditions in a movement laboratory. In a field study, the dynamic office chair was studied during three working days using accelerometry. Equivocal results showed that the dynamic chair increased upper body and chair movements as compared to the conventional chair, but lesser movements were found compared to standing. No differences were found between the conditions in the field study. A dynamic chair may facilitate movements in static desk-based office tasks, but the results were not consistent for all outcome measures. Validation of measuring protocols for assessing movements during desk-based office work is warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Jeong, In Cheol; Finkelstein, Joseph

    2015-01-01

    We developed a strengthening exercise support system which can be remotely managed and clinically supervised via internet. Older adults may potentially benefit from such an exercise system however functionality of this system requires validation before commencement of field studies in older adults. The aim of this study was to introduce and assess validity of a prototype telerehabilitation system supporting computer-assisted home-based strengthening exercise. The system included a resistance chair with a set of movement and physiologic sensors. Real-time feedback on exercise performance was displayed on a touch screen dashboard. Personalized exercise parameters were managed by a rehabilitation team via a designated telerehabilitation site. Assessment of the system demonstrated sufficient validity in real-time identification of exercise performance and cardiovascular parameters. We concluded that the interactive resistance chair has a potential in promoting strengthening exercise and it is warranted for further evaluation in community dwelling older adults.

    No literature related to the study of sitting forces on chairs sat on by people who weighed over 136 kg was found. The Business Institutional Furniture Manufactures Association needs force data for development of performance test standards to test chairs for users who weigh up to 181 kg. 20 participants who weighed from 136 to 186 kg completed 6 tasks on an instrumented chair in the sequence of sitting down, remaining seated and rising. Effects of sitting motion, armrest use and seat cushion thickness on vertical sitting forces and centre-of-force were investigated. Results indicated hard sitting down yielded the highest sitting force of 213% in terms of participants' body weights. Armrest use affected sitting forces of normal sitting down, but not of rising and hard sitting down. Cushion thickness affected sitting forces of normal and hard sitting down and shifting, but not of rising, static seating or stretching backward situations. Practitioner Summary: Results of the sitting force and centre-of-force data obtained for this research can help furniture manufacturers develop new product performance test standards for creating reliable engineering design and manufacturing quality and durable products to meet a niche market need.

  5. Bourdieu, Department Chairs and the Reform of Science Education

    NASA Astrophysics Data System (ADS)

    Melville, Wayne; Hardy, Ian; Bartley, Anthony

    2011-11-01

    Using the insights of the French sociologist, Pierre Bourdieu, this article considers the role of the science department chair in the reform of school science education. Using Bourdieu's 'thinking tools' of 'field', 'habitus' and 'capital', we case study the work of two teachers who both actively pursue the teaching and learning of science as inquiry. One teacher, Dan, has been a department chair since 2000, and has actively encouraged his department to embrace science as inquiry. The other teacher, Leslie, worked for one year in Dan's department before being transferred to another school where science teaching continues to be more traditional. Our work suggests that there are three crucial considerations for chairs seeking to lead the reform of science teaching within their department. The first of these is the development of a reform-minded habitus, as this appears to be foundational to the capital that can be expended in the leadership of reform. The second is an understanding of how to wield power and position in the promotion of reform. The third is the capacity to operate simultaneously and strategically within, and across, two fields; the departmental field and the larger science education field. This involves downplaying administrative logics, and foregrounding more inquiry-focused logics as a vehicle to challenge traditional science-teaching dispositions-the latter being typically dominated by concerns about curriculum 'coverage'.

    A rotation chair test has been used to evaluate the function of the horizontal semicircular canals. Currently, two chair systems according to the presence of cylindrical darkroom are used in a clinic setting. However, it has not been thoroughly investigated whether one system is superior to the other system or not. In this study, we aimed to compare test outcomes and subject convenience between two systems. Twenty subjects with no history of otologic disease were enrolled. Subjects were tested with two systems: system [A] with a cylindrical chamber and system [B] with no chamber. The results of sinusoidal harmonic acceleration (SHA), step velocity (SV), and visual fixation (VFX) tests were compared between the systems. Subject convenience was assessed with a questionnaire survey and results were compared between the systems. There were no significant differences in gain or asymmetry in SHA test between the systems. However, the phase of system [A] was significantly lower than that of system [B] at 0.16 Hz. There was no significant difference between the systems in directional preponderance (DP) gain or DP time constant. Regarding the VFX test, gain was higher in system [A] than system [B]. Subjects reported less stuffiness and less anxiety with system [B] than system [A], while preferring the system [A] goggles. A rotation chair system without a darkroom can provide a more comfortable experience for subjects in terms of stuffiness and anxiety, while showing comparable results in SHA and SV tests with a darkroom system.

    The aim of the current study was to find out how the measures of chairs and desks match with the anthropometrics of schoolchildren and how schoolchildren sit during a lesson in their classroom. This paper reports the baseline measurements of an intervention study. Participants of this study were 6th and 8th grade (12 and 14 year old) schoolchildren from two comprehensive schools in Finland (N = 101, 57 girls and 44 boys). The main outcome measures were the differences between desk height and elbow-floor height, and chair height and popliteal height. Forty-three participants were randomized for sitting posture analysis by video recordings. The study showed that desks were on average 13 cm above elbow-floor height and chairs 2 cm below popliteal height. For 56% of time participants sat with their backs flexed >20 degrees and/or rotated >45 degrees . For 70% of time they sat with their necks flexed >20 degrees or rotated >45 degrees. The results indicate that there is a mismatch between school furniture and the anthropometrics of schoolchildren. Schoolchildren sit in disadvantaged postures for a substantial part of school lessons.

    Objectives. Characterize the skills and abilities required for department chairs, identify development needs, and then create AACP professional development programs for chairs. Methods. A 30-question electronic survey was sent to AACP member department chairs related to aspects of chairing an academic department. Results. The survey identified development needs in the leadership, management, and personal abilities required for effective performance as department chair. The information was used to prioritize topics for subsequent AACP development programs. Subsequent programs conducted at AACP Interim and Annual Meetings were well attended and generally received favorable reviews from participants. A list of development resources was placed on the AACP website. Conclusions. This ongoing initiative is part of an AACP strategy to identify and address the professional development needs of department chairs. Survey results may also inform faculty members and other academic leaders about the roles and responsibilities of department chairs. PMID:22919099

    2012-01-01

    Background During shoulder surgery, blood pressure is frequently measured at the ankle. Anesthetic complications may result when ankle blood pressure is higher than brachial blood pressure and anesthesiologists misinterpret ankle blood pressure as brachial blood pressure. Therefore, we investigated whether ankle blood pressure is significantly higher than brachial blood pressure before anesthesia induction, during induction, after tracheal intubation, before beach chair position, and in the beach chair position. Methods Thirty patients requiring general anesthesia for shoulder surgery were included in this study. Ankle and brachial blood pressure were simultaneously measured before induction, during induction, after intubation, before beach chair position, and in the beach chair position. Results Ankle blood pressure was higher than brachial blood pressure before induction, during induction, after intubation, before beach chair position, and in the beach chair position. Ankle-brachial blood pressure differences in the beach chair condition were much higher than in four other conditions. The correlation coefficient between mean ankle-brachial blood pressure differences before the beach chair position and mean ankle-brachial blood pressure differences in the beach chair position was 0.616. Brachial systolic blood pressure could be predicted by regression equations (R2 = 0.306-0.771). Conclusions These results suggest that anesthesiologists should consider these ankle-brachial blood pressure differences when monitoring anesthesia in the beach chair position. PMID:23277812

    2013-01-01

    Although there is clinical and historical evidence for a vivid relation between the vestibular and emotional systems, the neuroscientific underpinnings are poorly understood. The “spin doctors” of the nineteenth century used spinning chairs (e.g., Cox’s chair) to treat conditions of mania or elevated arousal. On the basis of a recent study on a hexapod motion-simulator, in this prototypic investigation we explore the impact of yaw stimulation on a spinning chair on mood states. Using a controlled experimental stimulation paradigm on a unique 3-D-turntable at the University of Zurich we included 11 healthy subjects and assessed parameters of mood states and autonomic nervous system activity. The Multidimensional Mood State Questionnaire and Visual Analog Scales (VAS) were used to assess changes of mood in response to a 100 s yaw stimulation. In addition heart rate was continuously monitored during the experiment. Subjects indicated feeling less “good,” “relaxed,” “comfortable,” and “calm” and reported an increased alertness after vestibular stimulation. However, there were no objective adverse effects of the stimulation. Accordingly, heart rate did not significantly differ in response to the stimulation. This is the first study in a highly controlled setting using the historical approach of stimulating the vestibular system to impact mood states. It demonstrates a specific interaction between the vestibular system and mood states and thereby supports recent experimental findings with a different stimulation technique. These results may inspire future research on the clinical potential of this method. PMID:24133463

    2009-12-22

    Graphane is a two-dimensional system consisting of a single planar layer of fully saturated carbon atoms, which has recently been realized experimentally through hydrogenation of graphene membranes. We have studied the stability of chair, boat, and twist-boat graphane structures using first-principles density functional calculations. Our results indicate that locally stable twist-boat membranes significantly contribute to the experimentally observed lattice contraction. The band gaps of graphane nanoribbons decrease monotonically with the increase of the ribbon width and are insensitive to the edge structure. The implications of these results for future hydrogenated graphene applications are discussed.

    2016-01-01

    The most common benchmarks for faculty productivity are derived from Medical Group Management Association (MGMA) or Vizient-AAMC Faculty Practice Solutions Center(®) (FPSC) databases. The Association of Pathology Chairs has also collected similar survey data for several years. We examined the Association of Pathology Chairs annual faculty productivity data and compared it with MGMA and FPSC data to understand the value, inherent flaws, and limitations of benchmarking data. We hypothesized that the variability in calculated faculty productivity is due to the type of practice model and clinical effort allocation. Data from the Association of Pathology Chairs survey on 629 surgical pathologists and/or anatomic pathologists from 51 programs were analyzed. From review of service assignments, we were able to assign each pathologist to a specific practice model: general anatomic pathologists/surgical pathologists, 1 or more subspecialties, or a hybrid of the 2 models. There were statistically significant differences among academic ranks and practice types. When we analyzed our data using each organization's methods, the median results for the anatomic pathologists/surgical pathologists general practice model compared to MGMA and FPSC results for anatomic and/or surgical pathology were quite close. Both MGMA and FPSC data exclude a significant proportion of academic pathologists with clinical duties. We used the more inclusive FPSC definition of clinical "full-time faculty" (0.60 clinical full-time equivalent and above). The correlation between clinical full-time equivalent effort allocation, annual days on service, and annual work relative value unit productivity was poor. This study demonstrates that effort allocations are variable across academic departments of pathology and do not correlate well with either work relative value unit effort or reported days on service. Although the Association of Pathology Chairs-reported median work relative value unit productivity

    Regardless of the constantly increasing time man is spending in a sitting position, there is still a lack of objective chair quality assessment criteria. The aim of this paper is to find the answer to whether respiratory chest movement measurements can be a chair quality indicator. The study included 34 participants (mean 34.7 years±5.2). Their chest movements were assessed using respiratory inductive plethysmography while sitting on two subsequent chairs. Significant differences in chest movements depending on chair type were observed concerning the breathing duct (upper and lower) and breathing movement amplitude. The amplitude of the upper respiratory track in the first chair was higher (239.4 mV) compared with the second seat (207.3 mV) (p=.018). The analyzed parameters of respiratory chest movement may become a helpful indicator for design and selection of chairs which enable people to both work and relax in the most ergonomic conditions.

    Pressure ulcers remain a major source of morbidity and mortality in veterans with neurologic impairment. Management of pressure ulcers typically involves pressure relief over skin regions containing wounds, but this can lead to loss of mobility and independence when the wounds are located in regions that receive pressure from sitting. An innovative, low-cost, multidisciplinary effort was undertaken to maximize quality of life in a veteran with a thoracic-4 level complete spinal cord injury and a stage 4 ischial wound. The person's power wheelchair was converted into a motorized prone cart, allowing navigation of the Department of Veterans Affairs spinal cord injury hospital ward and improved socialization while relieving pressure on the wound. Physical and occupational therapy assisted with the reconfiguration of the power chair and verified safe transfers into the chair and driving of the device. Psychology verified positive psychosocial benefit, while nursing and physician services verified an absence of unwanted pain or skin injury resulting from use of the device. Further investigation of ways to apply this technique is warranted to improve the quality of life of persons with pressure ulcers.

    Strong evidence exists associating job satisfaction and risk of burnout with productivity, efficiency, and creativity in many organizations. However no data are available assessing chairs of surgery. This study assessed job satisfaction and risk for burnout of surgical chairs from Europe and North America and identified contributing factors. A survey among 650 chairs in surgery from 23 European and 2 North American countries was conducted in 2012. Satisfaction at work was analyzed using the validated Global Job Satisfaction (GJS) instrument and the abbreviated Maslach Burnout Inventory. Additional items targeting personal and environmental factors were included. The rate of chairs reached successfully was 86%, the overall response rate was 29% (188/650), with 1% female. Median age was 58 years. 11% of chairs were dissatisfied with work. Younger age and being fewer years in practice as a chair was associated with higher job satisfaction (P = .054 and P = .003). Surgical specialty with the greatest median GJS score was hepatopancreatobiliary, whereas vascular surgery scored lowest. Chairs desire to devote 20% more of their time on research. Clerical support as well as the ability to be innovative was suggested by 51% and 45%, respectively, to improve job satisfaction. Compared with Europeans, North American chairs were overall more satisfied and would recommend their job to their children. North American chairs seem to be more satisfied at work and at less risk for burnout than European chairs. The overall job satisfaction was greater among chairs compared with previously published reports of young, board-certified surgeons or residents (89% vs 87% and 66%, respectively). The superior satisfaction in chairs is strongest related to career achievements, innovation, and lifestyle. Copyright © 2014 Elsevier Inc. All rights reserved.

An effective onboarding program for these chairs can greatly facilitate early success, as well as satisfaction of the new hire with the position and the school. Onboarding programs can include traditional orientation items such as payroll signup and parking details, but should focus heavily on sharing organizational structure, culture, and how things get done. The goals of onboarding will be well served by implementation of three roles in the process. An Orientation Navigator can assist the new chair in the orientation phase, completing new employee documents and navigating the day-to-day challenges of working at the location. A Peer Mentor, generally a sitting chair, serves as both "buddy" and mentor, providing moral support as well as ensuring that the new chair gains an understanding of the people and processes important for getting things done. A Transition Mentor serves over a longer term as a sounding board and coach outside the peer group, assisting in a variety of ways to promote the chair's growth, development, and success as a leader. Finally, any onboarding process is significantly compromised without the active participation of the dean, meeting regularly with the chair to clarify expectations, promote assimilation, and solve problems. Successful onboarding begins with a mindfulness of the needs of the newly hired chair, and a well-designed and well-implemented plan will have wide-ranging benefits for the chair and the organization.

    To test the effects of the use of a collapsible, portable chair (chair B), as opposed to a 'standard' chair (chair A), on the outcome of the timed "Up and Go" (TUG) test. Cross-sectional. Multipurpose senior centres. Mobile older persons (N=118, mean age 77 years (range 62-99 years)). Time to complete the timed "Up and Go" test using chair A and chair B, and inter-rater agreement in the time scores. Time taken to complete the TUG test did not differ by chair type [median (interquartile range, IQR) = 12.3 (9.53-15.9) and 12.6 (9.7-16.6)] seconds for Chair A and B respectively, p-value=0.87. In multiple regression analyses, factors that impacted on time difference in test performance for the two chairs were use of a walking aid during the test [Odds ratio (OR) = 3.7 95%CI 1.1-11.9, p=0.031], observed difficulty with mobility (OR= 27.7 95%CI 2.6-290, p=0.006), and a history of arthritis in the knees (OR= 2.9 95%CI 1.0-8.7, P=0.05). In an inter-rater agreement analysis, no significant difference was found between time scores recorded by the two raters; median (IQR) = 12.4 (10.9-15.9) and 12.3 (7.2-59.1) seconds for the occupation therapist and for the research assistant, respectively (Wilcoxon matched pairs test, p=0.124, Spearman correlation coefficient = 0.99, p < 0.001). The use of a portable canvas chair with standardised specifications offers an acceptable alternative to the use of a 'standard' chair in assessments of fall risk using the TUG test in field settings where field workers are reliant on public transport.

  5. An International Survey of Approaches to Chair Restraint of Nonhuman Primates.

    Specifically designed restraint chairs are the preferred method of restraint for research studies that require NHP to sit in place for sustained periods of time. In light of increasing emphasis on refinement of restraint to improve animal wellbeing, it is important to have a better understanding of this potentially stressful procedure. Although chair restraint is used internationally, very little published information is available on this subject. We developed a survey to obtain an overview of equipment, procedures, and plans for improvement regarding chair restraint. We received 101 responses from people working in academic, government, contract research, and pharmaceutical laboratories within the Americas, Europe and Asia. Findings indicate that the majority of laboratories using restraint chairs work with macaque species. Restraint chairs are used for a wide range of procedures, including cognitive testing, recording neuronal activity, functional MRI, intravenous infusion, and blood sampling. Approximately 2/3 of laboratories use an enclosed 'box chair,' which the animal is trained to enter and then to extend its head through an opening on the top of the chair; the remaining one third of laboratories use an 'open chair' design, in which manual handling or the pole-and-collar system is used to transfer and secure the animal into the chair. Respondents reported that when selecting the type of chair to use, they considered comfort for the animal, ease of use, and the ability to adjust fit between animals of different sizes. Various training methods and timeframes are used to prepare macaques for restraint chair procedures. Several laboratories are incorporating greater use of positive reinforcement training. The community that uses these restraint procedures needs to work together to define best practice; our survey results can help in that effort.

  6. Learning to Generate Chairs, Tables and Cars with Convolutional Networks.

    We train generative 'up-convolutional' neural networks which are able to generate images of objects given object style, viewpoint, and color. We train the networks on rendered 3D models of chairs, tables, and cars. Our experiments show that the networks do not merely learn all images by heart, but rather find a meaningful representation of 3D models allowing them to assess the similarity of different models, interpolate between given views to generate the missing ones, extrapolate views, and invent new objects not present in the training set by recombining training instances, or even two different object classes. Moreover, we show that such generative networks can be used to find correspondences between different objects from the dataset, outperforming existing approaches on this task.

    This 1970 photograph shows the Rotating Litter Chair, a major component of Skylab's Human Vestibular Function experiment (M131). The experiment was a set of medical studies designed to determine the effect of long-duration space missions on astronauts' coordination abilities. The M131 experiment tested the astronauts susceptibility to motion sickness in the Skylab environment, acquired data fundamental to an understanding of the functions of human gravity reception under prolonged absence of gravity, and tested for changes in the sensitivity of the semicircular canals. Data from this experiment was collected before, during, and after flight. The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.

  9. American style or Turkish chair: the triumph of bodily comfort.

    PubMed

    Çevik, Gülen

    2010-01-01

    This article investigates the reciprocal influence of Ottoman Turkish and American interiors in the development of seating furniture. Seating furniture is unique because it involves a direct and physical interaction between the piece of furniture and the body, while at the same time it is part of a public space where social interactions occur. I will argue that the interactions between the Ottoman Turks and Americans are reflected in the way these traditions modified their seating furniture as they sought to mediate cultural, political and social differences between them. The concept of bodily comfort will serve as a common thread in understanding the origin of the expression "American style" (Amerikan stili or Amerikan tarzı) in modern Turkish language, the "Turkish chairs" in Victorian America in the late nineteenth century and the English language use of words such as sofa, ottoman and divan.

  11. Airline Chair-rest Deconditioning: Induction of Immobilization Thromboemboli?

    Air passenger miles will likely double by year 2020. The altered and restrictive environment in an airliner cabin can influence hematological homeostasis in passengers and crew. Flight-related deep various thromboemboli (DVT) have been associated with at least 577 deaths on 42 of 120 airlines from 1977 to 1984 (25 deaths/million departures), whereas many such cases go unreported. However, there are four major factors that could influence formation of possible flight-induced DVT: sleeping accomodations (via sitting immobilization), travelers' medical history (via tissue injury), cabin environmental factors (via lower partial pressure of oxygen and lower relative humidity), and the more encompassing chair-rest deconditioning (C-RD) syndrome. There is ample evidence that recent injury and surgery (especially in deconditioned hospitalized patients) facilitate thrombophlebitis and formation of DVT that may be exacerbated by the immobilization of prolonged air travel. In the healthy flying population immobilization factors associated with prolonged (> 5 hr) C-RID such as total body dehydration, hypovolemia and increased blood viscosity, and reduced various blood flow (pooling) in the legs may facilitate formation of DVT. However, data from at least four case-controlled epidemiological studies did not confirm a direct causative relationship between air travel and DART, but factors such as history of vascular thromboemboli, various insufficiency, chronic heart failure, obesity, immobile standing position, more than 3 pregnancies, infectious disease, long-distance travel, muscular trauma and violent physical effort were significantly more frequent in DVT patients than in controls. Thus, there is no clear, direct evidence yet that prolonged sitting in airliner seats, or prolonged experimental chair-rest- or bed- rest-deconditioning treatments cause deep various thromboemboli in healthy people.

    2014-01-01

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position. Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15). The last group was stepwise tilted to the sitting beach-chair position prior to surgery. Hypotension was treated with ephedrine. Continuous hemodynamic variables were recorded by photoplethysmography and frontal cerebral oxygenation (ScO2) by near infrared spectroscopy. Significant differences were only observed immediately after the induction when patients induced in a reclining beach-chair position had higher mean arterial pressure (MAP) (35 ± 12 vs. 45 ± 15 % reduction from baseline, p = 0.04) and ScO2 (7 ± 6 vs. 1 ± 8% increase from baseline, p = 0.02) and received less ephedrine (mean: 4 vs. 13 mg, p = 0.048). The higher blood pressure and lower need of vasopressor following induction of anesthesia in the reclining compared to the sitting beach-chair position indicate more stable hemodynamics with the clinical implication that anesthesia should not be induced with the patient in the sitting position.

    2012-01-01

    Aims: Genomic research can produce findings unrelated to a study's aims. The purpose of this study was to examine researcher and Institutional Review Board (IRB) chair perspectives on genomic incidental findings (GIFs). Methods: Nineteen genomic researchers and 34 IRB chairs from 42 institutions participated in semi-structured telephone interviews. Researchers and chairs described GIFs within their respective roles. Few had direct experience with disclosure of GIFs. Researchers favored policies where a case by case determination regarding whether GIF disclosure would be offered after discovery, whereas IRB chairs preferred policies where procedures for disclosure would be determined prior to approval of the research. Conclusions: Researcher and IRB chair perspectives on management of GIFs overlap, but each group provides a unique perspective on decisions regarding disclosure of GIFs in research. Engagement of both groups is essential in efforts to provide guidance for researchers and IRBs regarding disclosure of GIFs in research. PMID:22352737

    2011-01-01

    Effective leadership in academic medicine requires a broad constellation of skills, experiences, and core values. The authors sought to describe and define these. The authors conducted a web-based survey among 132 Chairs of North American departments of psychiatry. Eighty-five Chairs (64%) responded to the survey, the majority of whom were first-time Chairs. Identified leadership attributes included strategic/visionary acumen, interpersonal communication skills, core administrative and academic/technical skills, motivational capacity, personal integrity, and altruism/tenacity. The identified values are consistent with the leadership attributes that are described as necessary for success in the business community. Developing the required skill-set among faculty who aspire to become a departmental Chair is an important commitment for Deans and extant psychiatry Chairs. Copyright © 2011 Academic Psychiatry

    A single-subject design was used to assess the effectiveness of therapy ball chairs on classroom participation in 6 boys with autism spectrum disorder (ASD). The sensory processing pattern of each participant was assessed using the Sensory Processing Measure. Data on in-seat behavior and engagement were collected using digital video recordings during Circle Time. During baseline, participants sat on chairs. During intervention, participants sat on therapy ball chairs. Social validity was assessed by means of a questionnaire completed by the teacher. Each child demonstrated a unique response. The ball chair appeared to have a positive effect on in-seat behavior for the child who had the most extreme vestibular-proprioceptive-seeking behaviors. Children with poor postural stability were less engaged when sitting on the therapy ball chair. The results illuminate the complex nature of children with ASD and the importance of using sound clinical reasoning skills when recommending sensory strategies for the classroom.

    Determining gait speed as a measure of physical performance is recommended in diagnosing sarcopenia. Gait speed measurements require a certain amount of space (e.g. a 6-m course), and might not be feasible in clinical settings or heath checkup examination sites. We developed a formula to estimate chair stand time based on gait speed, and examined the validity (sensitivity and specificity) of using the estimated chair stand time cut-off point as a surrogate for the recommended gait speed cut-off point. Chair stand time was defined as the time it took to stand up from a standard chair five times. Gait speed was calculated from the time required for participants to walk a 6-m course at their usual pace. Simple regression analysis showed a significant negative relationship between chair stand time and gait speed (P < 0.0001), and the estimated formula was derived as follows: five times chair stand time = -8.41 × gait speed + 20.0 (R(2)  = 0.34). Therefore, the chair stand time cut-off point was estimated to be 13.3 s by inserting the recommended gait speed cut-off of 0.8 m/s in the above formula. Rounding off to make its use simpler, the estimated chair stand time cut-off was 13 s. The sensitivity and specificity of the estimated chair stand time cut off were 0.75 and 0.94, respectively. Chair stand time might be useful as a surrogate of gait speed when screening for sarcopenia. Geriatr Gerontol Int 2017; 17: 659-661. © 2016 Japan Geriatrics Society.

    The aim of this study was to investigate the effect of five chair designs on interface pressure distribution and tissue perfusion in the buttock-thigh region. Prolonged sitting has been found to contribute to the symptoms of work-related low back pain. Studies have found that chair design affects users' sitting posture and comfort. As sitting applies pressure to the user, it is necessary to investigate how chair design affects sitting pressure and tissue perfusion during sitting. We tested five chair designs (Suspension A, Suspension B, Foam A, Foam B, and bicompliant) on 15 young, healthy females. Sitting interface pressure and buttock-thigh tissue perfusion (in terms oftranscutaneous partial pressure of oxygen and carbon dioxide, tcPO2 and tcPCO2, respectively) were measured during 10-min sitting on each chair. We found that chair design significantly affected the distribution of the sitting pressure (p < .001) and buttock-thigh tissue perfusion (p < .023). Average pressure and total contact area were found highest in both foam designs, and the average pressure was the lowest in one of the suspension designs. Across all tested chair designs, the anterior portion of the seat sustained the lowest contact pressure. It was also found that tcPO2 was the lowest (p < .003) and tcPCO2 was the highest (p < .001) in tissue around ischial tuberosity for all chair designs. Chair design and materials of the seat significantly affect the sitting interface pressure distribution and tissue perfusion in sitting area. Further evaluation of these outcomes may provide useful information to correlate chair design with sitting comfort.

  13. Do we need a "Chair of alternative methods", and where?

    PubMed

    Wendel, Albrecht

    2002-01-01

    During the last two decades, the field of in vitro technology has been successfully developed and its use is continuously growing. Advanced tests avoiding animal experiments will be increasingly required for routine industrial applications e.g. for pharmacological high-throughput screening. Moreover and even more importantly, the availability of human cell based methods is essential for future quality assurance and risk assessment in the fields of health and consumer protection as well as environmental protection. Thereby, the potential of such advanced in vitro methods extends far beyond the mere replacement of regulated tests. In practice, the introduction and expansion of this technology has been achieved predominantly by offering funding and awards to the scientific community. After this initiation phase, the next consequent step to exploit this knowledge clearly consists in academic promotion of this new scientific culture in an institutionalised form. The tasks of such a chair focussed on advanced in vitro tests - most probably the first of its kind world-wide - would cover in addition to (a) research and (b) teaching, (c) the sharpening of social conscience for the topic. (a) While the validation of alternative methods was formally established by founding institutions like ZEBET in Berlin on the national and ECVAM in Ispra on the European level, the development of further new and more sophisticated in vitro methods to date emerge predominantly as a by-product of basic research. A considerable push might now be given by the structured search for new methods with a spill-over for research-based up-to-date teaching. (b) The field of alternative methods is more than a panel of advanced in vitro techniques: A culture of systematic evaluation and validation of in vitro tests has been developed, which has bearing far beyond the replacement of animal experiments. In vitro systems inherently prone to artefacts require the highest level of quality control and

    The United States (US) nuclear weapons program during the Cold War left a legacy of radioactive, hazardous, chemical wastes and facilities that may seriously harm the environment and people even today. Widespread public concern about the environmental pollution has created an extraordinary demand for the treatment and disposal of wastes in a manner to protect the public health and safety. The pollution abatement and environmental protection require an understanding of technical, regulatory, economic, permitting, institutional, and public policy issues. Scientists and engineers have a major role in this national effort to clean our environment, especially in developing alternative solutions and evaluation criteria and designing the necessary facilities to implement the solutions. The objective of the DOE Chair of Excellence project is to develop a high quality educational and research program in environmental engineering at North Carolina A&T State University (A&T). This project aims to increase the number of graduate and undergraduate students trained in environmental areas while developing a faculty concentrated in environmental education and research. Although A&T had a well developed environmental program prior to the Massie Chair grant, A&T's goal is to become a model of excellence in environmental engineering through the program's support. The program will provide a catalyst to enhance collaboration of faculty and students among various engineering departments to work together in a focus research area. The collaboration will be expanded to other programs at A&T. The past research focus areas include: hazardous and radioactive waste treatment and disposal fate and transport of hazardous chemicals in the environment innovative technologies for hazardous waste site remediation pollution prevention Starting from 2005, the new research focus was in the improvement of accuracy for radioactive contaminant transport models by ensemble based data assimilation.

    Evidence supports that surgeons are at high risk for work-related musculoskeletal disorders. The objective of the study was to compare the effect of different chairs on work-related musculoskeletal discomfort for surgeons during vaginal operations. This crossover study randomly assigned 4 surgeons to 4 chair types using a 4 × 4 Latin square model: a conventional round stool, a round stool with a backrest, a saddle chair with a backrest, and a Capisco chair. Subjective assessments of surgeon discomfort were performed with a validated body discomfort survey, and workload was assessed with the surgical task load index. The objective postural load was quantified with inertial measurement units of the modified rapid upper limb assessment limits. Subjective and objective assessments of chair comfort were performed with an 11 point scale and seat interface pressure-mapped distributions, respectively. The primary outcome was the difference in body discomfort scores between pre- and postsurgery measurements. Secondary outcomes were the differences in chair comfort scores, postural load, and seating interface pressure-mapped distribution. For each outcome, comparisons among the chair types were based on fitting a linear mixed model that handled the surgeon as a random effect and the chair type as a fixed effect. Data were collected for 48 vaginal procedures performed for pelvic organ prolapse. Mean (SD) duration of surgery was 122.3 (25.1) minutes. Surgeons reported body discomfort during 31 procedures (67.4%). Subjective increase in discomfort from the preoperative state was noted most commonly in the lower back (n = 14, 30.4%), followed by right shoulder (n = 12, 26.1%), upper back (n = 8, 17.4%), hips and buttocks (n = 7, 15.2%), left shoulder (n = 6, 13.0%), right or left thigh (n = 6, 13.0%), and neck (n = 6, 13.0%). Pre- and postsurgery body discomfort scores did not differ with respect to chair type. Chair discomfort scores for the round stool and the saddle

  12. How to be a department chair of epidemiology: a survival guide.

    PubMed

    Ness, Roberta B; Samet, Jonathan M

    2010-10-01

    As former chairs of 3 of the largest departments of epidemiology in the country, the authors provide "lessons learned" on how to be an epidemiology chair. To start, they suggest discussing strategic visioning with faculty, staff, and students; evaluating existing operational and governance structures; setting a predictable style; and considering which traditions to keep and which to modernize. Next, the authors consider key administrative issues. Recruitment and retention of the best faculty and students are critical to a successful department's future. A great department requires a great vision. To manage the change a new vision creates, the chair must attain buy-in and proceed with persistence. Chairs must promote the interests of the department to higher administration, a job best accomplished by being a team player and picking your battles. Keeping an eye on the mission involves balancing quality education with research and always striving to improve public health. Finally, a chair must continuously assess whether he or she is doing the best job. Eventually, the chair must know when to quit and how to quit well. Although being chair is demanding and sometimes difficult, it is a position that can be rewarding to both the individual and the department.

    If we are held more accountable for the appointment of women to the CRCs, if we take steps to ensure that nominations to the national CRCs committee are the result of a process that encourages applications directly from women candidates--and that includes a university-wide competition and peer review based on rigorous external assessment of candidates--and if we proactively and self-consciously seek to identify potential women candidates, we will have gone a long distance toward coupling equity and excellence in this program. If we add to these initiatives the training of search committees in successful strategies for identifying and recruiting women candidates, and the creation of employment conditions that acknowledge the reality of women's lives, including the reality of academic partners who need and merit academic positions, we will have gone an even greater distance toward success in appointing distinguished women to these prestigious Chairs. Moreover, we will have created practices that will serve us well in recruiting first-rate women to other academic appointments and that, in a virtuous circle, will improve the "pool" for future CRCs appointments.

    Purpose: Treating patients in a seated position has potential advantages including improved comfort, increased lung volume, and reduced respiratory motion. We compared chair designs for head and neck, thoracic and breast patients for use with either IGRT linacs or a proposed low-cost fixed horizontal beam-line machine. Methods: Three treatment chairs were designed and constructed. Two of the chairs are based on a massage-chair, with the patient angled slightly forwards and knee rests used to minimize intra-fraction slouch. The third chair design is more conventional; the patient is angled backwards, with indexed positioning devices and the ability to attach thermoplastic masks. Patient geometries, including PTV location and patient sizes, were extracted from 137 CTs of past patients were used to model the probability of collision between the patient and the linac for various seated positions. All chairs were designed around the weight limits for couches on our linacs. At the time of writing we have just received IRB approval for imaging studies to evaluate comfort, and intra- and interfraction reproducibility. Results: The geometric analysis showed that head and neck patients and thoracic patients could be treated without collision. However, there is very limited space between the patient and the treatment/imaging devices, so careful design of the chair is essential. The position of the treatment target and extended arm positioning means that this is a particular concern for thoracic and breast patients. This was demonstrated for one of the prototype chairs designed for breast treatment where the arm holders would collide with the kV detector. The extra clearance of a dedicated fixed-beam linac would overcome these difficulties. Intra- and inter-fraction reproducibility results will be presented at the meeting. Conclusion: To take advantage of the clinical advantages of seated treatments, appropriate treatment chairs are needed. A dedicate fixed-beam linac may

    Despite the strong representation of female psychiatrists in residency and early-career positions, the number of female faculty sharply decreases in tenured or executive leadership positions. Why there exists a marked change in representation at the level of senior leadership within academic psychiatry is unclear. The authors investigated the causative factors contributing to this observation and gathered information about the personal characteristics of women in executive leadership roles. The authors surveyed psychiatry chairs at academic institutions. They identified all female chairs and randomly selected a group of male chairs to serve as a control group. The survey assessed perceived barriers, strengths, and weaknesses and differences in demographics and leadership styles between female and male chairs. Ten percent of psychiatry chairs were female. Male chairs were more likely than female chairs to head large departments (p = 0.02, confidence interval (CI) -17.1-69.1) and had a higher H-index (p = 0.001, CI 6.6-37.2). Female chairs were more likely than male chairs to perceive barriers in their career development (p = 0.01, CI 0.7-2.2), citing little or no mentorship (p = 0.04), gender discrimination (p = 0.0001), and family obligations (p = 0.001) more often. Academic institutions must incorporate programs to decrease barriers and work to achieve equitable representation of women in upper-level leadership positions. Moreover, academic medicine must evolve to cultivate a family-friendly environment that successfully supports both genders.

    The purpose of this development project was to design a new commode-shower chair that can be safely used by individuals with spinal cord injuries (SCI) and their caregivers. The need for this new design was consumer-driven. Patients and caregivers identified the following fatal flaws in the commode-shower chairs used in Spinal Cord Injury (SCI) centers: 1) risk for patient falls during transfers, propelling, and while leaning over for showering; 2) risk for pressure ulcers due to inadequate padding and seat positioning for lengthy bowel care regimes; 3) inadequate caregiver access to the perianal area of the patient to perform bowel care procedures; and, 4) wheel-related inability to properly position the chair directly over the toilet. The new, self-propelled chair addresses each of these concerns. Lockable, swing-away, pivoting armrests and improved, lever-activated brakes were designed to facilitate safe transfers. An innovative foot-lift was invented to facilitate washing of feet. Larger handrims were designed to aid in propulsion in wet environments. To prevent pressure ulcers, a chair frame and padding combination was designed to facilitate a seating position that optimally distributes body weight to prevent the development of pressure ulcers in the sacral and ischial areas. To address the common risk of heel ulcers, footrests, featuring edgeless, rounded heel cups, were designed. A new tubular chair frame, a new seat and smaller wheels were designed to enhance caregiver access and ensure proper chair positioning over the toilet. Following its successful clinical evaluation at the Milwaukee and Tampa VA Medical SCI Centers, the Advanced commode-shower chair is being patented by the Department of Veterans Affairs (VA). The VA has partnered with Everest & Jennings, to make this chair available commercially.

    STS-42 Payload Specialist Roberta L. Bondar gets into the Microgravity Vestibular Investigations (MVI) rotator chair to begin an experiment. The chair is mounted in the center aisle of the International Microgravity Laboratory 1 (IML-1) spacelab (SL) module. Just above Bondar's head is the helmet assembly which is outfitted with accelerometers to measure head movements and visors that fit over each eye independently to provide visual stimuli. The chair system has three movement patterns: 'sinusoidal' or traveling predictably back and forth over the same distance at a constant speed; 'pseudorandom' or moving back and forth over varying distances; and 'stepped' or varying speeds beginning and stopping suddenly.

  19. Three essays on the economics of science policy: The impact of funding, collaboration and research chairs

    NASA Astrophysics Data System (ADS)

    Mirnezami, Seyed Reza

    This thesis studies the determinants that influence the number of citations, the effect of having a research collaboration with top-funded scientists on scientific productivity, and the effect of holding a research chair on scientific productivity. Based on a review study by Bornmann and Daniel (2008), one can argue that non-scientific factors determining the decision to cite do not significantly alter the role of citation as a measure of research impact. Assuming that the number of citations is a good measure for research impact and, in turn, for a certain kind of quality, we showed that the number of articles and the visibility of a researcher, the impact factor of the journal, the size of the research team, and the institutional setting of the university are the important determinants of citation counts. However, we have found that there is no significant effect of public funding and gender in most of the domains examined. The point that funding amount is not a significant determinant of citation counts does not necessarily contradict the positive effect of funding on scientific productivity. We also developed a theoretical model and proposed some hypotheses about the effect of collaboration with top-funded scientists on scientific productivity. We then validated the hypotheses with empirical analysis and showed that such collaboration has a positive effect on scientific productivity. This significant effect may exist through different channels: transfer of tacit knowledge, more scientific publications, economy of scale in knowledge production because of better research equipment, and expanded research network. The results also verified the positive effect of funding, the positive effect of networking (measured by number of co-authors), the inverted U-shaped effect of age, and the fewer number of publications by women compared to men. Finally, we made a distinction between different attributes of research chairs and their effect on scientific productivity. One

    It is unknown how vestibular dysfunction and age differentially affect balance control during functional activities. The objective of this study was to gain insight into the effects of age and vestibulopathy on head control when rising from a chair. Head relative to trunk (head-on-trunk) sagittal plane angular and linear control strategies were studied in patients with bilateral vestibular hypofunction (BVH) and in healthy subjects aged 30-80 years. A two-way analysis of variance was used to compare head-on-trunk kinematics by age (young vs elderly) and diagnosis (healthy vs BVH) at the time of liftoff from the seat. Angular control strategies differed with age but not diagnosis: young (healthy and BVH) subjects stabilized head rotations in space while elderly (healthy and BVH) subjects stabilized head rotations on the trunk. In contrast, linear control strategies differed by diagnosis but not age: BVH subjects (young and old) allowed a greater rate of head-on-trunk translation while healthy subjects (young and old) inhibited such translations. Young BVH subjects stabilized head-in-space rotations (as did young healthy subjects) without a functioning vestibular system, suggesting cervicocollic reflex and/or other sensory compensation for vestibular loss. Elderly BVH subjects stabilized head rotation with respect to the trunk, as did healthy elders, but did not stabilize head-on-trunk translations, suggesting a reliance on passive mechanical responses of the neck to sense head movements. We conclude that compensation strategies used by patients with vestibulopathy are age-dependent and appear to be more tractable in the younger BVH patient.

    The purpose of this study is to examine the range of vestibulo-ocular reflex (VOR) gain on rotary chair (RC) testing in subjects without ear and vestibular problems stratified by age and gender. Prospective cross-sectional study. One hundred subjects ranging in age from 6 to 78 years underwent RC testing. VOR gains at frequencies ranging from 0.01 to 0.64 Hz were recorded. The PROC MIXED procedure in SAS was used to analyze differences in VOR gain between gender and the following age groups: group 1 (6-12 years), group 2 (13-17 years), group 3 (18-30 years), group 4 (31-50 years), and group 5 (>50 years). Twenty subjects were recruited for each of the five groups. Group 1 showed the highest average VOR gain compared to all other age groups (P < .05). There was an inverse correlation between VOR gain and age (P < .05). The lowest frequency (0.01 Hz) had the highest correlation between VOR gain and age (r = -0.425; P < .0001). Our study demonstrates VOR gain differences with age, especially in the preadolescent and geriatric groups. The current manufacturer-provided normative data do not serve as an accurate reference, especially for these two age groups. A larger population of all age groups should be compared to the current RC manufacturer normative values to ensure that they accurately reflect the true normative data. 2. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Bispectral index (BIS) monitoring reduces the cases of intraoperative awareness. Several factors can alter BIS readings without affecting the depth of anesthesia. We conducted a study to assess the impact of beach chair position (sitting position) on BIS readings. General anesthesia was administered to 30 patients undergoing arthroscopic shoulder surgery. Patients were kept in neutral position (supine) for 10 minutes and BIS readings, mean arterial blood pressure, heart rate, end-tidal carbon dioxide, and end-tidal sevoflurane were recorded. Patients were then shifted to beach chair position. After 15 minutes, data were recorded. A significant decrease in BIS values (P < 0.01) associated with a position change from neutral position to beach chair position was evident. BIS values are significantly decreased in the beach chair position compared with the neutral position and might affect interpretation of the depth of anesthesia.

    Pediatric general and subspecialty care requires continuous effort to maintain knowledge and competencies in clinical practice. Equally important are efforts by investigators and educators to maintain knowledge and competencies in the conduct of research and training. The Association of Medical School Pediatric Department Chairs initiated a survey in July 2015 to define principles of lifelong learning in pediatric medicine and determine the approaches and strategies used by chairs to assess knowledge and competence across the care, research, and teaching missions. A total of 101 of 142 chairs (71%) completed the survey. Six of 7 proposed principles were endorsed by 84% to 96% of Association of Medical School Pediatric Department Chairs members. The focus areas included individual accountability, individually relevant activities, use of evidence-based guidelines/national standards, gaining cognitive expertise, learning as a continuous effort, affordability, and focus on individual understanding. The chairs endorsed a requirement for evidence of lifelong learning, competence, and compliance by all faculty members in clinical (n = 89 [88%]), research (n = 63 [62%]), and educational (n = 85 [84%]) practice. The survey identified the strategies to assess lifelong learning and faculty competence and compliance in clinical, research, and educational roles. Across missions, chairs endorsed an expectation for individual responsibility supplemented by formal evaluation practices and institutional and regulatory office oversight. While chairs endorsed an important role for the American Board of Pediatrics in assessing and verifying lifelong learning, knowledge, and competence in general and specialty certification, most (n = 91 [90%]) endorsed a need to revise current board requirements to better emphasize closing gaps in knowledge and using approaches that are evidence-based. This study provides the perspectives of pediatric department chairs on principles

    To explore the role played by human research ethics committees (HRECs) with regard to the fair inclusion of men and women in Australian clinical research. Semi-structured face-to-face and telephone interviews with 25 chairs (or their nominees) of Australian HRECs between 9 June 2006 and 24 January 2007. Chairs' views about the role of HRECs in identifying sex discrimination, monitoring the inclusion of men and women in clinical research, and interpreting and applying National Health and Medical Research Council (NHMRC) guidelines relating to fair inclusion in research. In general, HRECs do not take an active role in monitoring the sex of research participants. They do not ask for or often receive information about the sex of participants. Most HREC chairs did not believe that sex discrimination in research is currently a significant or widespread problem, and were confident that their committees would be able to identify arbitrary exclusion of either men or women from research. However, many chairs expressed a lack of familiarity with debates about sex equity in research. Most chairs were unaware that anti-sex-discrimination legislation could apply to research. "Fair inclusion" was interpreted in a number of ways by chairs, but most frequently that the sex balance among research participants should reflect the sex distribution in the community of the condition under investigation. Chairs said their committees would be reluctant to reject a research protocol on the grounds that the sex balance among participants was perceived to be unfair. Views about, and expertise on, sex equity in research vary among chairs of HRECs. Many HRECs require further guidance about the appropriate standards for fair inclusion of men and women in Australian clinical research.

    Gender-based bias and conflation of gender and status are root causes of disparities in women's health care and the slow advancement of women to leadership in academic medicine. More than a quarter of women physicians train in internal medicine and its subspecialties, and women physicians almost exclusively constitute the women's health focus within internal medicine. Thus, internal medicine has considerable opportunity to develop women leaders in academic medicine and promote women's health equity.To probe whether holding an endowed chair-which confers status-in women's health may be an effective way to advance women leaders in academic medicine and women's health, the authors explored the current status of endowed chairs in women's health in internal medicine. They found that the number of these endowed chairs in North America increased from 7 in 2013 to 19 in 2015, and all were held by women. The perceptions of incumbents and other women's health leaders supported the premise that an endowed chair in women's health would increase women's leadership, the institutional stature of women's health, and activities in women's health research, education, and clinical care.Going forward, it will be important to explore why not all recipients perceived that the endowed chair enhanced their own academic leadership, whether providing women's health leaders with fundraising expertise fosters future success in increasing the number of women's health endowed chairs, and how the conflation of gender and status play out (e.g., salary differences between endowed chairs) as the number of endowed chairs in women's health increases.

    Rearranging furniture in elementary school classrooms encourages classroom activities. In elementary schools in Indonesia and some other developing countries, usually only one style of furniture is used for all children, and the furniture is heavy and oversized for younger children. This affects their ability to carry it. The objective of this study is to investigate the effects of elementary school furniture weight and children’s age on performance of three carrying tasks (carrying a chair, lifting and turning a chair on a desk, and carrying both a chair and a desk together), from the ergonomics point of view. A total of 42 schoolchildren (ages 6–9; 17 Indonesian, 25 Japanese) participated in this study. Two types of Japanese chairs (Chair A and B, weight: 3.2 kg and 3.9 kg), one type of Indonesian chair (Chair C, weight: 5.0 kg), and two types of desks (height: 58 cm and 68 cm) were used. Indonesian chairs took significantly longer time to carry than the two Japanese chairs, and there was a significant negative relationship between age and task time for Chairs B and C, but not Chair A. Success rates for lifting and turning the chair declined as age decreased and chair weight increased, but were not significantly influenced by desk height. Success rates for carrying a chair and desk together significantly decreased with heavier furniture. Children aged six showed an extremely low success rate in almost all conditions. In conclusion, children’s ability to carry furniture is affected by their age and furniture characteristics, especially weight. In order to encourage classroom activities in elementary school, school furniture should be of appropriate weight. Supervision for younger children is required during classroom furniture arrangement.

    Due to the rapid growth in academic emergency departments over the past 20 years, recent significant changes in leadership have occurred. To prepare for future transitions, leaders in academic emergency medicine (EM) should identify those skills and characteristics desired in future academic chairs. The authors sought to determine which skills and characteristics are more important than others to help guide the development of EM-specific leadership courses. A survey of the current academic chairs in EM included questions pertaining to demographics, career time course, expected career longevity, and ratings of skills and characteristics deemed necessary for academic chairs. Chairs were asked to rate the qualities twice, to identify qualities that must be obtained prior to becoming chair, and those that may be obtained during chair tenure. Ninety-seven percent of the membership of the Association of Academic Chairs in Emergency Medicine (AACEM) completed the survey. Most chairs have been in practice for over 15 years, and a minority, for less than 10 years. One-third predict less than 6 more years in their current position, and almost 50% predict their careers as chair will continue an additional 6-10 years. The highest-rated formal training was an administrative or leadership training course or certification. Chairs noted that academic experience (including scholarly productivity, peer-reviewed publication, faculty development, and graduate medical education) was the most important skill set to obtain prior to becoming a chair, while hospital governance and cross-departmental collaboration skills can be obtained once in the role. Managerial skills were also felt to be of importance. Personal characteristics were overall rated highly. No differences were found between responses from early chairs and those later in their careers. Leadership courses for aspiring chairs in EM should foster the development of academic experience and managerial skills. Advanced degrees in

    Regardless of the constantly increasing time man is spending in a sitting position, there is still a lack of objective chair quality assessment criteria. The aim of this paper is to find the answer to whether respiratory chest movement measurements can be a chair quality indicator. The study included 34 participants (mean 34.7 years ± 5.2). Their chest movements were assessed using respiratory inductive plethysmography while sitting on two subsequent chairs. Significant differences in chest movements depending on chair type were observed concerning the breathing duct (upper and lower) and breathing movement amplitude. The amplitude of the upper respiratory track in the first chair was higher (239.4 mV) compared with the second seat (207.3 mV) (p = .018). The analyzed parameters of respiratory chest movement may become a helpful indicator for design and selection of chairs which enable people to both work and relax in the most ergonomic conditions.

    To determine hiring preferences among academic radiology department chairs with emphasis on recent residency and fellowship graduates. With the assistance of the Society of Chairs of Academic Radiology Departments (SCARD), an anonymous survey was distributed to academic radiology department chairs during the time period December 2014-March 2015, with additional reminder emails during the study period. Varied multiple choice questions were designed to gather information regarding program details; qualities most valued in new attending hires; level of difficulty recruiting subspecialty fellowship-trained radiologists; and the effect of the new ABR certification process on hiring practices. Descriptive statistics and analyses are reported. Surveys were completed by 79 of 184 eligible academic radiology chairs, a response rate of 43%. The most important hiring criteria cited were expertise in subspecialty, fellowship training, and perceived ability to work well with referring physicians. The most popular recruitment tools cited were hiring candidates from a chair's own program, journal ads, and academic networks. A minority of chairs (16%), primarily those of smaller departments, will not hire new graduates before completing board certification under the new certification structure (P = .0143). Expertise in a candidate's subspecialty was consistently cited as the most important hiring criterion. Changes to the ABR certification process, however, will affect hiring decisions, particularly within smaller academic departments. Copyright © 2015 AUR. Published by Elsevier Inc.

    Energy use in offices buildings is largely driven by air conditioning demands. But the optimal temperature is not the same for all building occupants, leading to the infamous thermostat war. And many occupants have independently overcome building comfort weaknesses with their own space heaters or fans. NREL tested is a customized office chair that automatically heats and cools the occupant along the seat and chair back according to the occupants' personal preferences. This product is shown to deliver markedly better comfort at room temperatures well above typical office cooling setpoints. Experimental subjects reported satisfaction in these elevated air temperatures, partly because the chair's cooling effect was tuned to their own individual needs. Simulation of the chair in office buildings around the U.S. shows that energy can be saved everywhere, with impacts varying due to the climate. Total building HVAC energy savings exceeded 10% in hot-dry climate zones. Due to high product cost, simple payback for the chair we studied is beyond the expected chair life. We then understood the need to establish cost-performance targets for comfort delivery packages. NREL derived several hypothetical energy/cost/comfort targets for personal comfort product systems. In some climate regions around the U.S., these show the potential for office building HVAC energy savings in excess of 20%. This report documents this research, providing an overview of the research team's methods and results while also identifying areas for future research building upon the findings.

    To compare the different techniques used by paramedics in handling an emergency evacuation chair and to identify themore ergonomically favourable technique, based on an analysis ofmuscular activity using surface electromyography. The trial was based on descending stairs, through four possible arrangements for the same transport operation, where the study variables were: worker anthropometrics (5th and 95th percentiles, corresponding to the extremes of the normal height-weight distribution curve), worker location during chair transport (upper or lower end of the chair), and the position of the individual at the lower end (facing front or backwards during descent). For both workers participating in the study, the more favourable working position during chair descent was at the lower end of the chairwhile facing forward, as this was associated with less muscular activity. In general, physical demands on the various muscles studied was greater for the worker corresponding to the 5th percentile (i.e., lower height-weight), except for the paravertebral musculature which, for certain maneuvers involving manipulation was significantly greater than the 95th percentile. When descending stairs while transporting an emergency evacuation chair, the position involving least muscular activity is located at the lower end of the chair, and descending while facing forwards.

    To know the effectiveness of a custom molded fitting chair between pre- and post-chair status through comparison of musculoskeletal indices in severely disabled children. We researched 34 severely disabled patients who had used a custom molded fitting chair continuously for more than a year. There were 27 cerebral palsy patients and 7 patients with other kinds of diseases that affect the brain such as chromosomal disease or metabolic disease. By radiographic studies, Cobb's angle, the femoral neck-shaft angle of the femur, and Reimers migration percentage were measured. The indices are analyzed before and after application. The average period of application was 24 months. There was a significant reduction in the angles of femur neck-shaft, 163.4 degree before and 158.2 degree after the use of the chair (p<0.05), and 23 of 34 had demonstrated a reduced angle. Cobb's angle and Reimers migration percentage increased but the difference of pre- and post-chair status was not statistically significant. Seventeen of 33 children showed reduced Cobb's angle. Also, 19 of 37 showed a reduced degree of dislocation of the hip joints. In spite of the use of a custom molded fitting chair, a significant improvement did not emerge for musculoskeletal deformity indices in severely disabled children. However, there was no significant aggravation of Cobb's angle or Reimers migration percentage in developing children. Therefore, it is thought be helpful to prevent rapid aggravation of musculoskeletal deformities.

    The newly formed Alliance of Directors and Vice Chairs of Education in Radiology (ADVICER), a group within the Alliance for Clinician Educators in Radiology, identified an acute need for a generic job description template for Vice Chairs of Education in Radiology, a role that is being developed in many academic Departments of Radiology. Eighty-three percent of current members who responded to a survey had no detailed job description, and over half had no job description at all. Having a comprehensive and detailed job description is vital to developing this key position. Using the results of a survey sent to ADVICER members and seven Education Vice Chair job descriptions provided by members, the authors developed a detailed job description encompassing all potential elements of this position. Only 17% of survey respondents had a detailed job description. The role of an Education Vice Chair varies significantly between institutions in its scope and level of responsibilities. The resultant generic job description that was devised is intended to provide a template that would be modified by the candidate or the Department Chair. It is unlikely that any one individual would perform all the described activities.

  1. Does Using a Chair Backrest or Reducing Seated Hip Flexion Influence Trunk Muscle Activity and Discomfort? A Systematic Review.

    PubMed

    This paper systematically reviews the effect of chair backrests and reducing seated hip flexion on low back discomfort (LBD) and trunk muscle activation. Prolonged sitting commonly exacerbates low back pain (LBP). Several modifications to seated posture and chair design have been recommended, including using chairs with backrests and chairs that reduce hip flexion. Electronic databases were searched by two independent assessors. Part 1 of this review includes 26 studies comparing the effect of sitting with at least two different hip angles. In Part 2, seven studies that compared the effect of sitting with and without a backrest were eligible. Study quality was assessed using the PEDro scale. Significant confounding variables and a relatively small number of randomized controlled trials (RCTs) involving people with LBP complicates analysis of the results. There was moderate evidence that chair backrests reduce paraspinal muscle activation, and limited evidence that chair backrests reduce LBD. There was no evidence that chairs involving less hip flexion reduce LBP or LBD, or consistently alter trunk muscle activation. However, participants in several studies subjectively preferred the modified chairs involving less hip flexion. The limited evidence to support the use of chairs involving less seated hip flexion, or the effect of a backrest, is consistent with the limited evidence that other isolated chair design features can reduce LBP. LBP management is likely to require consideration of several factors in addition to sitting position. Larger RCTs involving people with LBP are required. © 2015, Human Factors and Ergonomics Society.

    Specially designed chairs are expensive. A hand-made chair easily constructed from recycled material can be an alternative option. However data on the feasibility of hand-made chair use at home is limited. The present study aimed to explore the usage of a hand-made chair at home in children with moderate to severe motor disabilities. Seventeen children with cerebral palsy were recruited. Main caregivers were interviewed regarding the possibility of using the chair at home. Home visits and observations were also performed to explain how the chair had been used at home. Nine children (52.9%) used the chair everyday. Seven of these nine children were seated at least 30 minutes each time and two to three times per day. The total time that children spent on the hand-made chair each day ranged from 10 to 90 minutes. The severity of disability and main caregivers' workload may explain an inadequate usage of the hand-made chair. A few modifications may help to improve the applicability of the hand-made chair.

    Objective To assess academic emergency medicine (EM) chairs’ perceptions of quality improvement (QI) training programs. Methods A voluntary anonymous 20 item survey was distributed to a sample of academic chairs of EM through the Association of Academic Chairs of Emergency Medicine. Data was collected to assess the percentage of academic emergency physicians who had received QI training, the type of training they received, their perception of the impact of this training on behavior, practice and outcomes, and any perceived barriers to implementing QI programs in the emergency department. Results The response rate to the survey was 69% (N = 59). 59.3% of respondents report that their hospital has a formal QI program for physicians. Chairs received training in a variety of QI programs. The type of QI program used by respondents was perceived as having no impact on goals achieved by QI (χ2 = 12.382; p = 0.260), but there was a statistically significant (χ2 = 14.383; p = 0.006) relationship between whether or not goals were achieved and academic EM chairs’ perceptions about return on investment for QI training. Only 22% of chairs responded that they have already made changes as a result of the QI training. 78.8% of EM chairs responded that quality programs could have a significant positive impact on their practice and the healthcare industry. Chairs perceived that QI programs had the most potential value in the areas of understanding and reducing medical errors and improving patient flow and throughput. Other areas of potential value of QI include improving specific clinical indicators and standardizing physician care. Conclusion Academic EM chairs perceived that QI programs were an effective way to drive needed improvements. The results suggest that there is a high level of interest in QI but a low level of adoption of training and implementation. PMID:21293770

    During shoulder surgery, patients typically are placed in the beach chair position. In rare cases, this positioning has resulted in devastating outcomes of postoperative cerebral ischemia (Cullen and Kirby in APSF Newsl 22(2):25-27, 2007; Munis in APSF Newsl 22(4):82-83, 2008). This study presents a method to noninvasively and continuously hemodynamically monitor patients during beach chair positioning by using the photoplethysmograph signal recorded from a commercial pulse oximeter. Twenty-nine adults undergoing shoulder surgery were monitored before and after beach chair positioning with electrocardiogram, intermittent blood pressure, end tidal carbon dioxide, and photoplethysmograph via Nellcor finger pulse oximeter. Fast Fourier transform (FFT) was used to perform frequency-domain analysis on the photoplethysmograph (PPG) signal for data segments taken 80-120 s before and after beach chair positioning. The amplitude density of respiration-associated PPG oscillations was quantified measuring the height of the FFT peak at respiratory frequency. Results were reported as (median, interquartile range) and statistical analysis was performed using Wilcoxon sign rank test. Data were also collected when vasoactive drugs phenylephrine and ephedrine were used to maintain acceptable mean arterial pressure during a case. With beach chair positioning, all subjects who did not receive vasoactive drugs showed an increase in the FFT amplitude density of respiration-associated PPG oscillations (p < 0.0001) without change in pulse-associated PPG oscillations. The PPG was more accurate at monitoring the change to beach chair position than blood pressure or heart rate. With vasoactive drugs, pulse-associated PPG oscillations decreased only with phenylephrine while respiration-associated oscillations did not change. Frequency domain analysis of the PPG signal may be a better tool than traditional noninvasive hemodynamic parameters at monitoring patients during beach chair

    chairing the ILWS steering committee for the first two years. “There is a clear need to study the Sun and its interaction with the Earth” he says, “ and it is too big a job for a single space agency to cope with.” Notes to editors The new International Living With a Star (ILWS) programme builds upon a previous international framework between Europe, Japan, Russia (formerly the Soviet Union), and the United States to study the Sun and its effects on Earth. That framework was the International Solar Terrestrial Physics (ISTP) programme. The SOHO and Cluster missions were part of ESA’s contribution. For ILWS, the Canadian Space Agency has joined the collaboration. A ‘kick-off’ meeting between the space agencies involved in ILWS was held on 4-6 September 2002 in Washington DC, United States. An international steering committee of representatives from those agencies will now supervise the programme. The committee comprises five space agencies: the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), Japan's Institute for Space and Astronautical Science (ISAS), the Russian Aviation and Space Agency (Rosaviacosmos), and the Canadian Space Agency (CSA). There will be an ILWS Working Group to coordinate special projects. More than 20 space agencies have announced their participation in the first Working Group meeting, scheduled to take place in Nice, France, on 14 -15 April 2003. Contributions from the various space agencies include missions, payloads, subsystems, launch or tracking services, rockets, balloons, and open access to data sources.

  6. Seat pan and backrest pressure distribution while sitting in office chairs.

    2016-03-01

    Nowadays, an increasing amount of time is spent seated, especially in office environments, where sitting comfort and support are increasingly important due to the prevalence of musculoskeletal disorders. The aim of this study was to develop a methodology for chair-specific sensor mat calibration, to evaluate the interconnections between specific pressure parameters and to establish those that are most meaningful and significant in order to differentiate pressure distribution measures between office chairs. The shape of the exponential calibration function was highly influenced by the material properties and geometry of the office chairs, and therefore a chair-specific calibration proved to be essential. High correlations were observed between the eight analysed pressure parameters, whereby the pressure parameters could be reduced to a set of four and three parameters for the seat pan and the backrest respectively. In order to find significant differences between office chairs, gradient parameters should be analysed for the seat pan, whereas for the backrest almost all parameters are suitable.

    The authors aimed to (a) develop a scale to evaluate non-wheelchair-dependent children with Duchenne muscular dystrophy (DMD) while sitting and standing from the chair, (b) test its reliability, and (c) correlate the scores of this scale with the time, the age and the Vignos. Thirty DMD boys performed sit-to-stand and stand-to-sit from the chair 4 times. Scale development was based on a previous movement characterization in healthy children and in DMD children and on suggestions by physical therapists with expertise in DMD. The final version of the scale was submitted to the analysis of reliability. The sitting evaluation consists of phases: flexion, contact of the hip with the chair, extension. The standing evaluation comprehends the phases: flexion; transference; extension. Sitting and standing phases presented an excellent reliability (intraclass correlation coefficient [ICC] ≥ 0.91) and a good reproducibility (ICC ≥ 0.89). The scores generated by sitting on the chair correlated to the time taken to perform the tasks (r = .69) and to the age of the patient (r = .44) and the score of standing from the chair also correlated to the time of performance (r = .66). The sit-to-stand functional evaluation scale DMD is a reliable assessment tool that allows the description and quantification of the functional performance of DMD children.

    Using a quasi-experimental single-group design, this study examined the feasibility of older adults with Alzheimer's disease (AD)-type dementia to complete the Sit 'N' Fit Chair Yoga Program. Physical function of participants who completed the program was measured. The nine older adults with AD (mean age = 83) participated in the 8-week Sit 'N' Fit Chair Yoga Program. To measure physical function, the Six-Minute Walk Test, the Gait Speed Test, and the Berg Balance Scale were administered at pre-intervention, 4 weeks, 8 weeks, and 1 month after program completion. All participants completed the program. Positive changes were seen across all physical measures. Further study, using a larger sample and including a control group, is needed to fully determine the effect of the Sit 'N' Fit Chair Yoga Program on older adults with moderate to severe AD.

    Little has been documented regarding postoperative nursing interventions that are effective in decreasing postoperative recovery time, improving patient outcomes, or optimizing discharge readiness. A randomized study was conducted to evaluate 2 methods of recovery positioning and to examine factors that affect home readiness (eg, voiding, intake) for postsurgical laparoscopy patients. Participants were randomized into 2 groups. The control group was recovered in traditional hospital beds, while subjects in the experimental group recovered in a "recliner-chair," which was adjustable by the patient for comfort. The results showed that patients who recovered in adjustable recliner-chairs reached home readiness sooner and experienced greater comfort levels than patients who recovered in traditional hospital beds. Furthermore, patients in the recliner-chair group had fewer adverse symptoms such as nausea, severe pain, and delayed voiding. This is a U.S. government work. There are no restrictions on its use.

  11. Forget about ergonomics in chair design? Focus on aesthetics and comfort!

    PubMed

    Helander, Martin

    Chair users have difficulties distinguishing between chairs of different ergonomics quality. Many ergonomics features that are supposed to relieve discomfort in sitting are indistinguishable because they cannot be perceived. This is due to poor proprioceptive feedback from ligaments, joints and the spine. The joints are relatively insensitive to small changes in angle, and the spine cannot sense differences in pressure due to different body postures. Aesthetics features on the other hand, and features related to comfort and relaxation, are easier to perceive and differentiate. A study of ergonomics chairs verified that users could distinguish between parameters that relate to aesthetics and comfort, but had difficulty in distinguishing between ergonomics features. In the end aesthetics may be more important than ergonomics--at least to the customer who will be guided more by aesthetics than longer-term ergonomic factors.

    STS042-06-031 (30 Jan 1992) - - - STS-42 Payload Specialist Roberta L. Bondar gets into the Microgravity Vestibular Investigations (MVI) rotator chair to begin an experiment. The chair is mounted in the center aisle of the International Microgravity Laboratory 1 (IML-1) Spacelab (SL) module. Just above Bondar's head is the helmet assembly which is outfitted with accelerometers to measure head movements and visors that fit over each eye independently to provide visual stimuli. The chair system has three movement patterns: "sinusoidal" or traveling predictably back and forth over the same distance at a constant speed; "pseudorandom" or moving back and forth over varying distances; and "stepped" or varying speeds beginning and stopping suddenly.

    The aim of this pilot study was to examine whether chair yoga was effective in reducing pain level and improving physical function and emotional well-being in a sample of community-dwelling older adults with osteoarthritis. One-way repeated measures analysis of variance was performed to examine the effectiveness of chair yoga at baseline, midpoint (4 weeks), and end of the intervention (8 weeks). Although chair yoga was effective in improving physical function and reducing stiffness in older adults with osteoarthritis, it was not effective in reducing pain level or improving depressive symptoms. Future research planned by this team will use rigorous study methods, including larger samples, randomized controlled trials, and follow up for monitoring home practice after the interventions.

    In this paper, design of control system and power combination mechanism of a power assist system of the walking chair was discussed based on kinetostatic characteristics of human arm. The walking chair is a welfare walking machine which is an alternative vehicle of the wheelchair, and expected to be driven by user's cranking operation with assisting actuator. To efficiently utilize user power as much as possible for long locomotion without giving much fatigue to the user while providing comfortable driving feeling to the user, the human arm characteristics were taken into consideration. Kinetostatic characteristics of the human arm were experimentally investigated for its modeling. This model was applied to the design of mechanism and control system of the power assist system of the walking chair, and design parameters were determined for achieving comfortable driving feeling and efficient utilization of user power.

    Conflicting studies exist about the effectiveness of cardiopulmonary resuscitation (CPR) on a dental chair. In some situations, dental surgeons are obliged to perform CPR with the patient on the chair. Feedback devices are supposed to guide the compression depth in order to improve the quality of CPR, but some devices are based on an accelerometer that can theoretically report erroneous results because of the lack of rigidity of a dental chair. The aim of this study was to evaluate the accuracy of these devices to guide chest compressions on a dental chair. A prospective, randomised, crossover, equivalence/non-inferiority study was conducted to compare the values of compression depths provided by the feedback device (Real CPR Help(®), delivered by Zoll© Medical Corporation, Chelmsford, MA, USA) with the real measurements provided by the manikin (Resusci Anne(®) Advanced SkillTrainer, Laerdal Medical AS©, Norway). Chest-compression-only CPR was performed by 15 Basic Life Support instructors who carried out two rounds of continuous CPR for 2 min each. Data were analysed with a correlation test, a Bland-Altman method and a Wilcoxon test. Statistical significance was defined as p<0.05. A significant difference was found between the mean depths of compression measured by the feedback device and the manikin on a dental chair and on the floor (p<0.0001). The feedback device overestimated the depth of chest compressions, and Bland-Altman analysis demonstrated poor agreement. This study indicates that feedback devices with accelerometer technology are not sufficiently reliable to ensure adequate chest compression on dental chairs.

    The goal of the present study was to examine changes of middle cerebral artery (VMCA) blood flow velocity in patients scheduled for shoulder surgery in beach chair position. Prospective observational study. Operating room, shoulder surgery. Fifty-three consecutive patients scheduled for shoulder surgery in beach chair position. Transcranial Doppler performed after induction of general anesthesia (baseline), after beach chair positioning (BC1), during surgery 20minutes (BC2), and after back to supine position before stopping anesthesia (supine). Mean arterial pressure (MAP), end-tidal CO2, and volatile anesthetic concentration and VMCA were recorded at baseline, BC1, BC2, and supine. Postoperative neurologic complications were searched. Beach chair position induced decrease in MAP (baseline: 73±10mm Hg vs lower MAP recorded: 61±10mm Hg; P<.0001) requiring vasopressors and fluid challenge in 44 patients (83%). There was a significant decrease in VMCA after beach chair positioning (BC1: 33±10cm/s vs baseline: 39±14cm/s; P=.001). The VMCA at baseline (39±2cm/s), BC2 (35±14cm/s), and supine (39±14cm/s) were not different. The minimal alveolar concentration of volatile anesthetics, end-tidal CO2, SpO2, and MAP were not different at baseline, BC1, BC2, and supine. Beach chair position resulted in transient decrease in MAP requiring fluid challenge and vasopressors and a moderate decrease in VMCA. Copyright © 2016 Elsevier Inc. All rights reserved.

    Pain related to the gurney is a frequent complaint of older emergency department (ED) patients. The authors hypothesized that these patients may have less pain and higher satisfaction if allowed to sit in a reclining hospital chair. A single-blind, randomized controlled trial was performed. Patients 65 years old or older who were able to sit upright, transfer, and engage in normal conversation were eligible. Severely ill or cognitively impaired patients were excluded. Patients were randomized to either remain on the gurney or transfer to the chair after initial evaluation. Patients reported pain at arrival (t0), at one hour (t1), and at two hours (t2) using a 0-10 pain scale, and satisfaction at study completion on a 0-10 scale. The primary outcome was a decrease in pain between t0 and t1 or no pain at both t0 and t1. This outcome was analyzed using a 95% confidence interval for the difference between proportions; exclusion of zero was considered significant. Sixty-six patients in each group were enrolled. There was no difference in demographics between groups, but the chair patients were more likely to have pain at t0 than the gurney patients. More chair patients than gurney patients had a successful primary outcome (97% vs. 76%, 21% difference, 95% CI=10% to 32%). The mean satisfaction score was higher in the chair group than in the gurney group (8.1 vs. 6.0, 2.1 difference, 95% CI=1.4% to 2.8%). The simple modification of allowing older ED patients to sit in reclining chairs resulted in less pain and higher satisfaction.

    The leadership position of an academic departmental chair can be a positive and rewarding opportunity. These rewards principally stem from the success of the faculty, residents, other trainees, nurses, and everyone supporting the department. With health care reform and the constraints of the federal budget, increasing attention and time has become directed toward administrative management. There are multiple and often competing constituencies and agendas requiring thoughtful strategies to achieve departmental goals. The objectives of a chair are advancing patient care, education, and research. True excellence of a department is achieved by the innovation of its faculty. © 2015 The Authors.

    2013-04-01

    Purpose: To identify objective characteristics and benchmarks for program leadership in academic radiation oncology. Methods and Materials: A study of the 87 Accreditation Council for Graduate Medical Education radiation oncology training program directors (PD) and their chairs was performed. Variables included age, gender, original training department, highest degree, rank, endowed chair assignment, National Institutes of Health (NIH) funding, and Hirsch index (H-index). Data were gathered from online sources such as departmental websites, NIH RePORTER, and Scopus. Results: There were a total of 87 PD. The median age was 48, and 14 (16%) were MD/PhD. A total of 21 (24%) were female, and rank was relatively equally distributed above instructor. Of the 26 professors, at least 7 (27%) were female. At least 24 (28%) were working at the institution from which they had received their training. A total of 6 individuals held endowed chairs. Only 2 PD had active NIH funding in 2012. The median H-index was 12 (range, 0-51) but the index dropped to 9 (range, 0-38) when those who served as both PD and chair were removed from the group. A total of 76 chairs were identified at the time of the study. The median age was 55, and 9 (12%) were MD/PhD. A total of 7 (9%) of the chairs were female, and rank was professor for all with the exception of 1 who was listed as “Head” and was an associate professor. Of the 76 chairs, at least 10 (13%) were working at the institution from which they received their training. There were a total of 21 individuals with endowed chairs. A total of 13 (17%) had NIH funding in 2012. The median H-index was 29 (range, 3-60). Conclusions: These data provide benchmarks for individuals and departments evaluating leadership positions in the field of academic radiation oncology. Such data are useful for evaluating leadership trends over time and comparing academic radiation oncology with other specialties.

    Prolonged sitting has been associated with musculoskeletal dysfunction. For desk workers, workstation modifications frequently address the work surface and chair. Chairs which can prevent abnormal strain of the neuromuscular system may aid in preventing musculo-skeletal pain and discomfort. Anecdotally, adjustability of the seat height and the seat pan depth to match the anthropometrics of the user is the most commonly recommended intervention. Within the constraints of the current economic climate, employers demand evidence for the benefits attributed to an investment in altering workstations, however this evidence-base is currently unclear both in terms of the strength of the evidence and the nature of the chair features. The purpose of this study was to evaluate the evidence for the effectiveness of chair interventions in reducing workplace musculoskeletal symptoms. Pubmed, Cinahl, Pedro, ProQuest, SCOPUS and PhysioFocus were searched. 'Ergonomic intervention', 'chair', 'musculoskeletal symptoms', 'ergonomics', 'seated work' were used in all the databases. Articles were included if they investigated the influence of chair modifications as an intervention; participants were in predominantly seated occupations; employed a pre/post design (with or without control or randomising) and if the outcome measure included neuro-musculoskeletal comfort and/or postural alignment. The risk of bias was assessed using a tool based on The Cochrane Handbook. Five studies were included in the review. The number of participants varied from 4 to 293 participants. Three of the five studies were Randomised Controlled Trials, one pre and post-test study was conducted and one single case, multiple baselines (ABAB) study was done. Three studies were conducted in a garment factory, one in an office environment and one with university students. All five studies found a reduction in self-reported musculoskeletal pain immediately after the intervention. Bias was introduced due to poor

    Wheelchairs are a major advance in enabling independence for people with walking difficulties. The first self-propelled wheelchair has been attributed to John Joseph Merlin, the 'ingenious mechanick', in the early 19th century and his 'gouty chair' is exhibited at Kenwood House. Research would suggest that comparable chairs existed in France as early as 1751 and the French Revolutionary, Georges Couthon, used one to get around Paris. A later design, also attributed to Merlin, the invalid wheelchair, features large wheels with outer hoops for the occupant to grasp and this is the true ancestor of the modern wheelchair. © The Author(s) 2016.

    The concept of an ideal sitting posture is often used in practice but lacks a basis in evidence. We designed a cross-sectional, comparative, matched study to determine the effects of chair and posture on lumbar curvature in 10 patients with chronic non-specific low back pain (CLBP; mean pain duration 24 ± 18 months) and 10 healthy matched controls. Pelvic incidence, sacral slope and lumbar curvature were measured on computed radiographs by 2 blinded clinicians for subjects in 2 postures (upright vs slumped sitting) and on 2 chairs (usual flat chair vs kneeling chair). The reliability of measures was excellent (intraclass correlation coefficient>0.9). As hypothesized, the expected sacral slope and lumbar lordosis changed between standing and sitting on a kneeling chair as compared with a usual chair (P<0.0001) and less in patients than controls (P=0.046) for lordosis only. In addition, as expected, changes were more pronounced with slumped than upright sitting (P<0.0001). An interaction between chairs and postures for lumbar lordosis (P=0.02) indicated more pronounced effects of the chair in slumped sitting. Therefore, lumbar lordosis was reduced less when sitting on a kneeling chair as compared with a usual chair. Although healthy subjects showed more reduction in lordosis between standing and sitting, the chair effect was found in both CLBP patients and healthy subjects. Copyright © 2015 Elsevier Masson SAS.

    Low back pain (LBP) is a common musculoskeletal disorder and prolonged sitting often aggravates LBP. A novel dynamic ergonomic chair ('Back App'), which facilitates less hip flexion while sitting on an unstable base has been developed. This study compared lumbar posture and trunk muscle activation on this novel chair with a standard backless office chair. Twelve painfree participants completed a typing task on both chairs. Lumbar posture and trunk muscle activation were collected simultaneously and were analysed using paired t-tests. Sitting on the novel dynamic chair significantly (p < 0.05) reduced both lumbar flexion and the activation of one back muscle (Iliocostalis Lumborum pars Thoracis). The discomfort experienced was mild and was similar (p > 0.05) between chairs. Maintaining lordosis with less muscle activation during prolonged sitting could reduce the fatigue associated with upright sitting postures. Studies with longer sitting durations, and in people with LBP, are required. Sitting on a novel dynamic chair resulted in less lumbar flexion and less back muscle activation than sitting on a standard backless office chair during a typing task among pain-free participants. Facilitating lordotic sitting with less muscle activation may reduce the fatigue and discomfort often associated with lordotic sitting postures.

  4. Clinical introduction of a commercial treatment chair to facilitate thorax irradiation.

    PubMed

    Klein, E E; Wasserman, T; Ermer, B

    1995-01-01

    There are occasions when patients can benefit significantly from being treated upright. This technique is beneficial in the treatment of Hodgkin's disease when the mediastinum is involved. The main benefit is the lung volume spared resulting from narrowing of a bulky mediastinum. We purchased a commercial treatment chair to facilitate upright treatment. Clinical implementation required rigorous testing, documentation of procedures, and acknowledgment of and corresponding solutions to limitations. The purchased chair is designed to couple with the spine bar of the treatment couch, allowing patient positioning via pendant functions. The chair has no obstruction as immobilization is afforded by arm, shoulder, and knee supports, which allows isocentric treatments. An additional hydraulic mount is used for simulation. We have treated five patients thus far, including Hodgkin's disease patients with and without mediastinal involvement, and one lung cancer patient with a large lower lobe lesion. All patients have benefited by having a greater volume of lung spared (as much as 60% additional blocking) when upright simulation films are compared with supine and prone films. Immobilization has been adequate as confirmed by daily light field projections and portal films. We are routinely evaluating Hodgkin's disease patients for upright treatment. Patients treated in the chair have benefited in terms of lung volume spared without loss of immobilization. A patient with a large lower lobe lung lesion has also benefited as the tumor "dropped," thus affording lung sparing via blocking.

    2014-01-01

    An open-label randomized controlled trial was conducted to clarify the effect of eldecalcitol (ED) on body balance and muscle power in postmenopausal osteoporotic women treated with bisphosphonates. A total of 106 postmenopausal women with osteoporosis (mean age 70.8 years) were randomly divided into two groups (n=53 in each group): a bisphosphonate group (control group) and a bisphosphonate plus ED group (ED group). Biochemical markers, unipedal standing time (body balance), and five-repetition chair-rising time (muscle power) were evaluated. The duration of the study was 6 months. Ninety-six women who completed the trial were included in the subsequent analyses. At baseline, the age, body mass index, bone mass indices, bone turnover markers, unipedal standing time, and chair-rising time did not differ significantly between the two groups. During the 6-month treatment period, bone turnover markers decreased significantly from the baseline values similarly in the two groups. Although no significant improvement in the unipedal standing time was seen in the ED group, compared with the control group, the chair-rising time decreased significantly in the ED group compared with the control group. The present study showed that ED improved the chair-rising time in terms of muscle power in postmenopausal osteoporotic women treated with bisphosphonates. PMID:24476669

    Special Region of Yogyakarta (DIY) is known as city for academic. Many people come to get some education in college. They live in boarding house with some supporting facilities. The most common facilities is low table which lead students have to sit on the floor while studying on table which could cause higher risk of back pain and musculoskeletal disorder. To identify the solution to reduce back pain and musculoskeletal risk, it is needed to design a lesehan chair which also appropriate to customer needs. Kansei engineering method was used with a total of 30 respondents participated, 15 kansei words collected, and 12 kansei words selected by doing validation and reliability test. The result of this study showed that quality, aesthetics, and comfort level influence the design of lesehan chair. A design of lesehan chair was created by considering the suitable concept and merging it with the physical design and its anthropometry measurement. In this case, marginal homogeneity test is needed to identify the differences between each kansei words attribute and the design or product recommendation. The marginal homogeneity test results show that the design and product recommendation has fulfilled customer's desires and needs. For further research, it is needed to analyse and evaluate the posture of lesehan chair users in order to develop and improve its performance.

    2012-01-01

    Since the introduction of ergonomic guidelines in the design of office chairs, a lot of effort has been put in designing these office chairs accordingly. Because these features all have to be adjusted in different ways (mostly a knob underneath the seat surface), and because every office chair offers different solutions, often users do not use all of the adjustments, and thus do not use the office chair an the optimal ergonomic way. The aim of this paper is to study the influence of feedback on sitting habits of office workers in a field test during 4 weeks. 40 office workers were selected for this test (13 male, 27 female). They were divided in three groups. A control group, a group that received a sitting instruction and a group that received sitting instruction and feedback on their posture every hour that they sit. The results show that there is an effect in average increase in basic posture on both the group that received instruction and the group that received feedback. This effect decreases over time. There was no effect in the control group.

    2015-11-01

    Varying the inclination of the dental chair backrest might alter the distribution of occlusal contact points. The purpose of this study was to identify the influence of backrest inclination on the registration of the mandibular position. Ten participants aged between 18 and 30 years with a complete permanent dentition, uncompromised motor function, no tooth mobility, and no temporomandibular disorders were selected. To register interocclusal contacts, an autopolymerizing methylmethacrylate device was adapted to the maxillary anterior teeth and a composite resin increment was added to the mandibular central incisors. Contacts were registered with the following variations in the inclination of the dental chair backrest: 90 degrees, 120 degrees, and 180 degrees. A standardized digital photograph was made of each mark in each backrest position, and the images were superimposed to measure the distances in registration from 90 to 120 and from 90 to 180 degrees. Data were analyzed with the Student paired t test (α=.05). When the chair was inclined from the 90-degree to the 120-degree position, the mandible was repositioned posteriorly by a mean of 0.67 mm, but the difference was not statistically significant. When the chair was inclined from the 90-degree to the 180-degree position, however, the mandible was repositioned posteriorly by a statistically significant mean of 1.41 mm. Mandibular position is influenced by increasing inclination, and this influence was statistically significant at a 180-degree incline.

    To investigate the association between sarcopenia and "chair stand test" performance, and evaluate this test as a screening tool for sarcopenia in community-dwelling elderly women. Cross-sectional Survey. 173 female individuals, aged ≥ 60 years and living in the urban area of the municipality of Lafaiete Coutinho, Bahia's inland, Brazil. The association between sarcopenia (defined by muscle mass, strength and/or performance loss) and performance in the "chair stand test" was tested by binary logistic regression technique. The ROC curve parameters were used to evaluate the diagnostic power of the test in sarcopenia screening. The significance level was set at 5 %. The model showed that the time spent for the "chair stand test" was positively associated (OR = 1.08; 95% CI = 1.01 - 1.16, p = 0.024) to sarcopenia, indicating that, for each 1 second increment in the test performance, the sarcopenia's probability increased by 8% in elderly women. The cut-off point that showed the best balance between sensitivity and specificity was 13 seconds. The performance of "chair stand test" showed predictive ability for sarcopenia, being an effective and simple screening tool for sarcopenia in elderly women. This test could be used for screening sarcopenic elderly women, allowing early interventions.

    The aim of this study was to evaluate the commercial chair-side assays Saliva-Check Mutans and ClinproTM Cario L-PopTM in high microbiological caries-risk dental students compared with conventional semi-quantitative colony counting culture-based technique as the reference method. Saliva samples from 93 subjects of both sexes aged 18-26 years were seeded (Köhler and Bratthall method) on plates containing SB-20M culture medium method and 12 subjects with high caries risk were selected. These 12 individuals were subjected to determination of caries risk using two commercial rapid detection chair-side assays (Saliva-Check Mutans and ClinproTM Cario L-PopTM) according to the manufacturers' instructions. The results were analyzed by the Kappa correlation test using SAS statistical software. There was a perfect agreement (Kappa=1) among the three caries risk evaluation methods - chair-side assays and semi-quantitative CFU count (control) - in all subjects. The results suggest that the commercial chair-side assays evaluated in this study may be practical and useful to identify high microbiological caries-risk subjects.

    2005-02-01

    Stimulation of the vestibular system has been reported to elicit ventilatory and circulatory changes in humans. The purpose of this study was to clarify the characteristics of vestibular-mediated ventilatory and circulatory responses in male endurance runners at the onset of passive chair rotation, which selectively stimulates the semicircular canals. Fourteen runners and 14 male untrained subjects participated. The vestibular stimulus test, which consists of 180 degrees chair rotations (left or right half-turns on an earth-vertical axis) for a duration of 2 s, was carried out on each subject. Inspiratory minute ventilation, tidal volume, respiratory frequency, heart rate, and blood pressure were measured by breath-by-breath and beat-to-beat techniques before, during, and after the chair rotation for a total of 60 s. It was found in this study that (i) the relative change of minute ventilation response in the endurance runners was significantly (P < 0.05) greater than in the untrained subjects during and after the rotation, and that (ii) no significant group differences were observed in heart rate and mean blood pressure responses during and after the rotation. In conclusion, vestibular-mediated ventilatory response, but not circulatory response, at the onset of the chair rotation in the endurance runners was significantly greater than that in the untrained subjects. The results from the present study suggest that an increase in vestibulo-ventilatory response would be attributed to an adaptation to long-term endurance training.

  14. Two assistive technology devices for children: an adjustable reacher and a lunch room chair.

    PubMed

    Stephens, Michael; Barrett, Steven F

    2005-01-01

    Two devices were modified and redesigned to further improve on previous designs and to better suit the children they were originally constructed for. The first device is a reacher that needs to be adjustable. The child originally needed a reacher that was small enough to operate. Adult reachers were shortened to fit the child. It became apparent that the reachers would need to be able to grow with the child. For that reason a reacher was developed with interchangeable center sections and control rods. This allows the reacher to grow with child in increments without the need to keep sending the reacher in for modification. The reacher also needs to pinch on a different plane then it is controlled at to simplify use for the child. The second device modified was a chair built for children in wheel chairs to allow for them to sit with their peers at a lunch table at school. The chair was totally redesigned to be more comfortable and stronger. A removable cover was added so that it can be washed. A leg rest with adjustable foot rests was added so the children's feet are well supported and they are comfortable. This chair will allow the children to sit anywhere in the cafeteria so that they may sit with their peers.

  17. Chair alarm for patient fall prevention based on gesture recognition and interactivity.

    PubMed

    Knight, Heather; Lee, Jae-Kyu; Ma, Hongshen

    2008-01-01

    The Gesture Recognition Interactive Technology (GRiT) Chair Alarm aims to prevent patient falls from chairs and wheelchairs by recognizing the gesture of a patient attempting to stand. Patient falls are one of the greatest causes of injury in hospitals. Current chair and bed exit alarm systems are inadequate because of insufficient notification, high false-alarm rate, and long trigger delays. The GRiT chair alarm uses an array of capacitive proximity sensors and pressure sensors to create a map of the patient's sitting position, which is then processed using gesture recognition algorithms to determine when a patient is attempting to stand and to alarm the care providers. This system also uses a range of voice and light feedback to encourage the patient to remain seated and/or to make use of the system's integrated nurse-call function. This system can be seamlessly integrated into existing hospital WiFi networks to send notifications and approximate patient location through existing nurse call systems.

    [Purpose] We assessed the effects of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work. [Subjects] Ten males were recruited. [Methods] The suspension seat support was developed to prevent abnormal gluteal pressure and a slumped sitting posture during computer work. The gluteal pressure was measured with a TekScan system and the trunk flexion angle was measured with a video camera, to compare the differences between a general chair and the suspension seat support. [Results] The gluteal peak pressures were decreased significantly in the suspension seat support versus the general chair. The trunk flexion angle was also decreased significantly in the suspension seat support compared with the general chair. [Conclusions] This study suggests that the suspension seat support chair contributes to preventing abnormal gluteal pressure and a slumped sitting posture. PMID:26504341

    Tiihonen, Miia; Hartikainen, Sirpa; Nykänen, Irma

    2017-07-01

    The aim of this study was to investigate the ability of older home-care clients to perform the five times chair rise test and associated personal characteristics, nutritional status and functioning. The study sample included 267 home-care clients aged ≥75 years living in Eastern and Central Finland. The home-care clients were interviewed at home by home-care nurses, nutritionists and pharmacists. The collected data contained sociodemographic factors, functional ability (Barthel Index, IADL), cognitive functioning (MMSE), nutritional status (MNA), depressive symptoms (GDS-15), medical diagnoses and drug use. The primary outcome was the ability to perform the five times chair rise test. Fifty-one per cent ( n=135) of the home-care clients were unable to complete the five times chair rise test. Twenty-three per cent ( n=64) of the home-care clients had good chair rise capacity (≤17 seconds). In a multivariate logistic regression analysis, fewer years of education (odds ratio [OR] = 1.11, 95% confidence interval [CI] 1.04-1.18), lower ADL (OR = 1.54, 95% CI 1.34-1.78) and low MNA scores (OR = 1.12, 95% CI 1.04-1.20) and a higher number of co-morbidities (OR = 1.21, 95% CI 1.02-1.43) were associated with inability to complete the five times chair rise test. Poor functional mobility, which was associated with less education, a high number of co-morbidities and poor nutritional status, was common among older home-care clients. To maintain and to prevent further decline in functional mobility, physical training and nutritional services are needed. (NutOrMed, ClinicalTrials.gov Identifier: NCT02214758).

  9. Association between chair stand strategy and mobility limitations in older adults with symptomatic knee osteoarthritis.

    To determine which lower limb strength and joint kinetic and kinematic parameters distinguish sit-to-stand (STS) performance of older adults with symptomatic knee osteoarthritis (OA) with higher and lower chair stand time. Cross-sectional. Motion analysis laboratory. Individuals (N=49; 26 men, 23 women) aged 50 to 79 years (mean ± SD age, 64.7±8.1y) with radiographic knee OA and daily symptoms, stratified by chair stand times. Not applicable. Lower limb strength and STS strategy. The chair stand times (mean ± SD) in the high-, moderate-, and low-functioning groups in men were 6.5±0.7, 8.6±0.7, and 11.5±1.3 seconds, respectively, and in women were 7.6±1.2, 10.0±0.5, and 12.8±1.8 seconds, respectively. Chair stand time (P=.0391) and all measures of lower limb strength (all P<.0001) differed by sex. In men, no strength measure differed between groups, whereas in women hip abductor strength on the more affected side differed between groups. In men, sagittal hip range of motion (ROM) (P=.0122) differed between groups, and there was a trend toward a difference in sagittal knee power (P=.0501) during STS, while in women only sagittal knee ROM (P=.0392) differed between groups. Higher- and lower-functioning adults with symptomatic knee OA appear to use different strategies when standing from a chair. Higher-functioning men flexed more at the hip and produced greater knee power than lower-functioning men. Higher-functioning women used less knee flexion than lower-functioning women. Since STS is an important mobility task, these parameters may serve as foci for rehabilitation aimed at reducing mobility limitations. Copyright © 2013 American Congress of Rehabilitation Medicine.

    Strasbourg occupied during the 19th century a privileged place in chemistry, as well in education as in research, and that in particular in three institutions created after the dissolution of the old University during the French Revolution: the Faculty of Sciences, the School then Faculty of Medicine created in 1794, and the School of Pharmacy created in 1804. In 1871, Alsace was annexed by Germany. The chair of medical chemistry in the Faculty of Medicine was successively occupied by: Pierre François Nicolas (1743-1816) in 1794-1795, Frédéric Louis Ehrmann (1741-1801) from 1796 to 1798, Gabriel Masuyer (1761-1849) from 1798 to 1838, and Amédée Cailliot (1805-1884) from 1838 to 1871. The chair of chemistry in the School of Pharmacy was successively occupied by: Louis Hecht (1771-1857)from 1804 to 1835, Jean François Persoz (1805-1868) from 1835 to 1852, Adrien Loir (1816-1899) from 1852 to 1855, Charles Frédéric Gerhardt and Eugène Théodore Jacquemin (1828-1909) from 1856 to 1871.

  17. Does agreement on institutional values and leadership issues between deans and surgery chairs predict their institutions' performance?

    2007-03-01

    To gain a better understanding of the values that medical school deans and surgery chairs consider most essential for effective leadership, to assess their perceptions of the values and leadership climate in their institutions, and to test the premise that agreement on leadership values and climate predict greater organizational effectiveness and performance. From June 2005 through March 2006, questionnaires designed to assess leadership core values and organizational leadership climate were mailed to medical school deans and surgery chairs of the 125 U.S. academic health centers. Institutional performance measures used were the National Institutes of Health (NIH) standing and U.S. News and World Report ranking of each institution. Sixty-eight surgery chairs (54%) and 60 deans (48%) returned surveys. Q-sort results on 38 positive leadership values indicated that integrity, trust, and vision were considered the most important core values for effective leadership by both chairs and deans. Both groups ranked business acumen, authority, and institutional reputation as least important. Deans consistently ranked the leadership climate as being healthier (more positive) than did their surgery chairs on multiple scale items: leadership is widely shared (P = .005), information is widely shared (P = .002), missions are aligned (P = .003), open communication is the norm (P = .009), good performance is rewarded (P = .01), teamwork is widely practiced (P = .01), and leaders are held accountable (P = 002). Tighter alignment between chairs and deans on core values and on the leadership climate scale correlated with higher school and department NIH standing and higher U.S. News and World Report medical school and hospital ranking (P < .05). Although surgery chairs and deans espouse similar core leadership values, deans believe that a healthier leadership climate exists in their institutions than their surgery chairs do. The study findings suggest that tighter leadership alignment

    The purpose of this study was to develop and validate an evaluation instrument for tablet arm chairs based on ergonomic requirements, focused on user perceptions and using Item Response Theory (IRT). This exploratory study involved 1,633 participants (university students and professors) in four steps: a pilot study (n=26), semantic validation (n=430), content validation (n=11) and construct validation (n=1,166). Samejima's graded response model was applied to validate the instrument. The results showed that all the steps (theoretical and practical) of the instrument's development and validation processes were successful and that the group of remaining items (n=45) had a high consistency (0.95). This instrument can be used in the furniture industry by engineers and product designers and in the purchasing process of tablet arm chairs for schools, universities and auditoriums. PMID:28337099

    The adjustable sitting inclination rehabilitation chair was fabricated with mild steel and soft upholstered fabric was used for the overlay on the seat, headrest and armrest. The components were coupled with a linear actuator at the upper frame for the reclining of the backrest about it axis. The wheels are located outboard of the seat of the chair to enhance stability while foot rest supports the posterior weight of the users. The narrow seat allows free movement of the leg when the user is seated. Sitting inclinations of 120 and 135° protect the spine disc from compression and proffer more comfort for the users than other angles experimented. The adjustable sitting inclination SCRC is simple and affordable for low-income people with Spinal cord injury, especially for those in developing countries in order to support other therapies for their recovery processes.

    STS042-27-037 (22-30 Jan. 1992) --- Astronaut David C. Hilmers, STS-42 mission specialist, wearing a helmet assembly, sits in the Microgravity Vestibular Investigation (MVI) rotating chair. The scene is in the International Microgravity Laboratory (IML-1) science module aboard Discovery. Hilmers, a mission specialist, and six other crewmembers spent more than eight days in Earth-orbit conducting experiments. Hilmer's helmet assembly is outfitted with accelerometers to measure head movements and visors that fit over each eye independently to provide visual stimuli. The chair system has three movement patterns: "sinusoidal" or traveling predictably back and forth over the same distance at a constant speed; "pseudorandom" or moving back and forth over the varying distances; and "stepped" or varying speeds beginning and stopping suddenly.

    Little is known about the use of online dissemination strategies, such as websites and social media, to increase the visibility and uptake of research. To describe two online dissemination strategies of the Canada Research Chair in Implementation of Shared Decision Making in Primary Care over an eight-year period. Our two sources of online dissemination data were the website of the Canada Research Chair in Implementation of Shared Decision Making in Primary Care and the Chair's Twitter account. We conducted a content analysis of the news section of the website. We extracted website usage statistics using Google Analytics and analyzed indicators such as total number of visits, new and returning visitors, page views per visit, time spent onsite per visit, visitors' country of origin, and most popular pages. From the Chair's Twitter account, we collected the number of tweets, followers, and follows. We consulted Google Scholar to chart the trend in citations of the Chair's articles over the same period. From the website's inception in January 2008 to December 2015, we recorded an average of 7906 visits per year (3809 in 2008; 8874 in 2015), 65.85% of which involved new visitors (5206/7906). The average number of pages viewed per visit was 3.2 and average bounce rate was 57.87% (4575/7906). Visitors spent an average of two minutes and 12 seconds per visit. We computed visits from 162 countries, with the majority from Canada (5910/7906, 74.75%). In order of frequency, the seven most visited pages were: (1) home page with news of publications and grants (24,787 visits), (2) profile of Chairholder (8041 visits), (3) profiles of research team members (6272 visits), (4) list of research team members (4593 visits), (5) inventory of shared decision making (SDM) programs (1856 visits), (6) interprofessional approaches to SDM (1689 visits), and (7) description of Chair activities (1350 visits).

Three key tenets of effective surgery leadership that arose from these sessions deal with the importance of (1) collaboration and cooperativity, (2) humanized relationships and mentorship, and (3) operational efficiency. Overall, the panel consensus for the future of surgery leadership was optimistic while recognizing that the demands of chairmanship are considerable.

    Prism adaptation has been used for several years to improve several aspects of unilateral neglect. Parameters ranging from the classical neuropsychological tests to mental imagery or to tactile extinction have been successfully ameliorated following a brief period of adaptation to wedge prisms shifting the visual field to the right. However the potential therapeutic implications of this technique depend on the investigation of more functional and ecological parameters. Here we describe a patient with left hemiplegia and unilateral neglect who was impaired during wheel-chair navigation in the clinical unit. Following a brief adaptation period, this patient showed a sudden improvement of wheel-chair driving as well as of classical tests. The potential implications of prism adaptation for the rehabilitation of unilateral neglect are highlighted by the long duration of improvement obtained after a single adaptation session.

    The growing appreciation of the need to adopt an evidence-based approach to teaching and assessment has led to a demand for faculty who are well versed in best practices in education. Surgeons with interest and expertise in instruction, curriculum development, educational research, and evaluation can have an important impact on the educational mission of a department of surgery. The increased fervor for accountability in education together with the challenges imposed by accreditation agencies and hospitals has made educational leadership responsibilities more time consuming and complex. In response to this, an increasing number of department chairs created Vice Chair for Education positions to support clerkship and program directors and ensure the department's education mission statement is fulfilled.

    We sought to improve the sitting postures of children studying in the classrooms of a primary school. We made the seat of a standard chair lower and attached a cushion designed by one of the authors. The cushion is cut at a 25° downward angle toward the legs to allow the users to support their weight with their feet and alleviate pressure on the underside of the thighs. We also lowered the desktop to below the height of children's elbows. Eighty-three children were given the new chairs and desks, and they were observed over 7 months. Around 10% of them voluntarily maintained good sitting postures; others straightened their postures when the teachers reminded them to do so.

    Gait speed, maximum grip strength and thirty seconds chair stand test are quick, reliable measures of functional capacity in older adults. The objective of this study was to develop normative data of the said parameters, which is lacking in older Indians. In a cross sectional study, 723 participants of ≥60 years without any morbidity, were recruited with written consent at Geriatric Medicine clinic of All India Institute of Medical sciences, New Delhi. Time taken to walk comfortably (4m) was taken as Gait speed. Maximum grip strength was assessed by using dynamometer by pressing it for 3 times in each hand, and the best of six values noted. Thirty second chair stand was assessed by the number of repetitions to stand and sit from a chair in thirty second. The Cut-off (25th percentile) of gait speed for both male and female in all age group was 0.6m/s. The Cut-off for maximum grip strength in 60-65 years, 66-70 years and >70 years for male were 20, 15 and 15 and for females were 8, 6 and 6 in kg, respectively. The Cut-off for thirty second chair stand test in 60-65 years, 66-70 years and >70 years for male were 10, 9 and 8 and for females was 8, 8 and 7, respectively. These normative data would be useful to the clinicians and researcher as Indian reference value, which is less as compared to western data. Community based multi-centre study is needed.

    People working at computers often suffer from overload-related muscle pain, and physical and mental discomfort. The aim of the study was to evaluate the effectiveness of chair massage, conducted in the workplace among white-collar workers, in relieving symptoms of musculoskeletal strain related to prolonged sitting posture. The study was conducted in 124 white-collar workers, 55 women and 69 men, aged 33.7 ± 7.6 years. Subjects were randomly assigned to three groups: chair massage program, relaxing music sessions, and a control group, each of four-week duration. Each group was evaluated before and after the program completion. Pain perception was assessed algometrically as a threshold for compression pain of neck muscles, measured in kg/cm(2). The relaxation level was assessed from the heart rate variability. We found that the chair massage increased both the pain threshold in all tested muscles (p < 0.001) and the relaxation level from 31.9% to 41.6% (p < 0.05). In the group with music sessions, muscle pain threshold remained unchanged, except for the trapezoid muscle where it decreased (p < 0.05), while the relaxation level increased from 26.0% to 33.3% (p < 0.05). In both massage and relaxing music groups, there was a significant decrease in muscle tension (p < 0.01). Changes in the control group were inappreciable. We conclude that the chair massage performed in the workplace is an effective method for prevention of musculoskeletal overstrain related to prolonged sitting posture. The program seems worth implementing in various occupational environments.

    Unstable sitting on a wobble chair with different balance difficulty levels can be used as an effective tool in exercises as well as evaluation and therapeutic stages of rehabilitation. No data on muscle activity levels and spinal loads are however available to assess its safety compared to other regular daily activities. The goal of this study was to estimate muscle forces and spinal loads in a seated unstable wobble chair task. In vivo 3D kinematics of the trunk and seat collected in an earlier study were used here to drive computational trunk musculoskeletal models of 6 normal and 6 low-back pain subject groups sitting on a wobble chair for a duration of 10s. Results revealed no significant differences between kinematics, muscle forces, spinal loads and force plate reaction forces when comparing these two groups. The estimated muscle forces and spinal loads were moderate though larger than those in a stationary sitting posture. Local spinal forces at the L5-S1 disc varied with time and reached their peaks (1473 N and 1720 N in compression, 691 N and 687 N in posterior-anterior shear and 153 N and 208 N in right-left shear, respectively for healthy and CLBP groups) being much greater relative to those in the stationary sitting posture (means of 12 subjects: 768 N, 284 N and 0 N, respectively). The wobble chair with characteristics considered in this study is found hence safe enough as a therapeutic exercise for both healthy and low-back pain subjects. Copyright © 2016 Elsevier Ltd.

    This paper presents DC servo motor speed control characteristics by fuzzy logic controller and considers position following control response with controller. A sinusoidal rotatory chair system using an auto tuning fuzzy PID control was designed to evaluate the vestibular function. Then the system is investigated for the effects of change by the fuzziness of fuzzy variable. If this system is supported by a channel, it is considered for application in industry of multi joint robot and precision parallel driving.

    To determine the effects of the relative inactivity and unloading on the strength of the tibias of monkeys, Macaca mulatta, we used a non-invasive test to measure bending stiffness, or EI (Nm2), a mechanical property. The technique was validated by comparisons of in vivo measurements with standard measures of EI in the same bones post-mortem (r2 = 0.95, P < 0.0001). Inter-test precision was 4.28+/-1.4%. Normative data in 24 monkeys, 3.0+/-0.7 years and 3.6+/-0.6 kg, revealed EI to be 16% higher in the right than left tibia (4.4+/-1.6 vs. 3.7+/-1.6 Nm2, P < 0.05). Five monkeys, restrained in chairs for 14 days, showed decreases in EI. There were no changes in EI in two chaired monkeys that lost weight during a 2-week space flight. The factors that account for both the decreases in bone mechanical properties after chair restraint at 1 g and lack of change after microgravity remain to be identified. Metabolic factors associated with body weight changes are suggested by our results.

    The effects of external water pressure on intercompartmental fluid volume shifts and endocrine responses in man are investigated. Extracellular fluid volumes and plasma and urine electrolyte and endocrine responses of four male subjects were measured during eight hours of head-out water immersion and 16 hours of recovery bed rest and compared to responses obtained during eight hours of chair rest and 16 hours of bed rest without external hydrostatic pressure obtained in the same subjects five months later. Immersion is found to result in a substantial diuresis with respect to chair rest, accounted for by decreases in extracellular volume. A negative water balance during immersion and a positive water balance during chair rest were observed to be accompanied by a shift of extracellular volume to the intracellular compartment, as well as the suppression of plasma arginine vasopressin and renin activities in both regimes. The vasopressin and renin activity decreases are attributed to the increased central blood volume, and half of the plasma loss in immersed subjects is attributed to the effects of external water pressure.

  12. In vivo spinal posture during upright and reclined sitting in an office chair.

    Increasing numbers of people spend the majority of their working lives seated in an office chair. Musculoskeletal disorders, in particular low back pain, resulting from prolonged static sitting are ubiquitous, but regularly changing sitting position throughout the day is thought to reduce back problems. Nearly all currently available office chairs offer the possibility to alter the backrest reclination angles, but the influence of changing seating positions on the spinal column remains unknown. In an attempt to better understand the potential to adjust or correct spine posture using adjustable seating, five healthy subjects were analysed in an upright and reclined sitting position conducted in an open, upright MRI scanner. The shape of the spine, as described using the vertebral bodies' coordinates, wedge angles, and curvature angles, showed high inter-subject variability between the two seating positions. The mean lumbar, thoracic, and cervical curvature angles were 29 ± 15°, -29 ± 4°, and 13 ± 8° for the upright and 33 ± 12°, -31 ± 7°, and 7 ± 7° for the reclined sitting positions. Thus, a wide range of seating adaptation is possible through modification of chair posture, and dynamic seating options may therefore provide a key feature in reducing or even preventing back pain caused by prolonged static sitting.

    EOS imaging (EOS System; EOS imaging, Paris, France) enables fast 2-D/3-D imaging of children in standing load-bearing position. Non-ambulatory children with neuromuscular scoliosis need evaluation of their spinal balance while in a normal daily position. We designed a customized chair fitting the EOS patient-area dimensions to obtain images in natural sitting postures. The chair is a 360° rotating orthopaedic chair made of fully radiolucent polyethylene and equipped with an adjustable headrest and three-point belts. Out of 41 consecutive patients, 36 (88%, 95% confidence interval 74-96%) had successful imaging. In most patients with severe neuromuscular trunk deformities, the EOS system combined with our chair was useful for assessing preoperative trunk collapse, pelvic obliquity and postoperative corrections in all planes. This specific device changed our daily practice for the assessment of spinal deformities in non-ambulatory patients.

    Radiotherapy in a seated position may be indicated for patients who are unable to lie on the treatment couch for the duration of treatment, in scenarios where a seated treatment position provides superior anatomical positioning and dose distributions, or for a low-cost system designed using a fixed treatment beam and rotating seated patient. In this study, we report a novel treatment chair that was constructed to allow for three-dimensional imaging and treatment delivery while ensuring robust immobilization, providing reproducibility equivalent to that in the traditional supine position. Five patients undergoing radiation treatment for head-and-neck cancers were enrolled and were setup in the chair, with immobilization devices created, and then imaged with orthogonal X-rays in a scenario that mimicked radiation treatments (without treatment delivery). Six subregions of the acquired images were rigidly registered to evaluate intra- and interfraction displacement and chair construction. Displacements under conditions of simulated image guidance were acquired by first registering one subregion; the residual displacement of other subregions was then measured. Additionally, we administered a patient questionnaire to gain patient feedback and assess comparison to the supine position. Average inter- and intrafraction displacements of all subregions in the seated position were less than 2 and 3 mm, respectively. When image guidance was simulated, L-R and A-P interfraction displacements were reduced by an average of 1 mm, providing setup of comparable quality to supine setups. The enrolled patients, who had no indication for a seated treatment position, reported no preference in the seated or the supine position. The novel chair design provides acceptable inter- and intrafraction displacement, with reproducibility equivalent to that reported for patients in the supine position. Patient feedback will be incorporated in the refinement of the chair, facilitating treatment of

    The author argues that a particular kind of departmental leadership is needed lest medical education become hostage both to distant management through regulatory metrics (which can displace local, institutional creativity) and to the financial pressures within the institution. Departmental chairs themselves have often been seen as barriers to successful integration and redesign of medical school curricula. The vice-chair for education is a critical figure in achieving this new kind of leadership.The author describes three forms of curriculum planning and management: phase 1, where the department chair makes the decisions; phase 2, dominated by regulation from above (in part a reaction to problems with the phase 1 approach); and phase 3, the author's vision of an approach in which decisions occur within departments but with an awareness of the institution as a collaborative system, and grounded in educational theory and research. The vice-chair for education would have a key role, carrying out interdepartmental planning and assessment for the chairs, who would provide them the needed time, training (in leadership and in educational theory and practice), support (from professional educators, with advanced degrees in education), and routes to academic advancement.Responding effectively to a complex and changing environment requires senior leaders at the middle-management level (such as vice-chairs for education) who are well trained in both the content of their specialties and also in interpersonal and collaborative skills, and who have the desire to reach a common future.

    We report, for what we believe is the first time, generation of stable chair-like pulses (a pulse shape with an initial long flat portion followed by a short high peak power portion resembling the shape of a chair) by mode locking of a Ytterbium (Yb)-doped fiber laser. Chair-like pulse shapes are achieved by implementing dual saturable absorbers, one based on a nonlinear optical loop mirror (NOLM) and the other based on nonlinear polarization rotation (NPR) inside the cavity. The transmission characteristics of the NOLM-NPR pair leading to the formation of chair-like pulses are numerically investigated. We also report the amplification characteristics of chair-like pulses in an external multistage Yb-doped fiber amplifier setup at different repetition rates of the pulse train. It was found that the chair-like pulses are suitable for amplification, and more than 10 W of average power at 460 kHz repetition rate have been obtained at total pump power of ∼20  W coupled to the power amplifier. At a lower repetition rate (115 kHz), ∼8  W of average power were obtained corresponding to ∼70  μJ of pulse energy with negligible contribution from amplified spontaneous emission or stimulated Raman scattering. We believe that such an oscillator-amplifier system could serve as an attractive tool for micromachining applications.

    Muscle atrophy and weakness impair activity of daily living (ADL). We examined whether chair stand exercise can improve ADL of hemodialysis patients. A randomized controlled trial. A single center study. Outpatients on hemodialysis older than 60 years (61-79 years). Twelve weeks of intervention with chair stand exercise, 3 sessions/week versus the control exercise (stretch, 1 session/week). The primary outcome was the change in functional independence measure (FIM) score from baseline. The secondary outcomes were changes in thigh circumference, muscle strength of quadriceps, 6-minute walking distance, maximum duration of chair stand exercise, health-related quality of life, cognitive function serum albumin, and hemoglobin. Among the 27 patients who were randomized, 17 completed the study. The change in FIM from baseline was greater in the intervention group (1 [1-3] vs. 0 [0-0], median (minimum to maximum), P < .001) due to the significant improvement in the FIM subscales related to mobility (bed/chair/wheel chair) and locomotion (stair). Among the secondary outcomes, significant difference was noticed in the changes in thigh circumference and the physical component summary score of health-related quality of life by Medical Outcome Study 36-Item Short-Form Health Survey (SF-36v2). Chair stand exercise improved ADL in the hemodialysis patients aged older than 60 years. Copyright © 2015 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

    Aging populations are increasing worldwide and strategies to minimize the impact of falls on older people need to be examined. Falls in hospitals are common and current hospital technological implementations use localized sensors on beds and chairs to alert caregivers of unsupervised patient ambulations; however, such systems have high false alarm rates. We investigate the recognition of bed and chair exits in real-time using a wireless wearable sensor worn by healthy older volunteers. Fourteen healthy older participants joined in supervised trials. They wore a batteryless, lightweight and wireless sensor over their attire and performed a set of broadly scripted activities. We developed a movement monitoring approach for the recognition of bed and chair exits based on a machine learning activity predictor. We investigated the effectiveness of our approach in generating bed and chair exit alerts in two possible clinical deployments (Room 1 and Room 2). The system obtained recall results above 93% (Room 2) and 94% (Room 1) for bed and chair exits, respectively. Precision was >78% and 67%, respectively, while F-score was >84% and 77% for bed and chair exits, respectively. This system has potential for real-time monitoring but further research in the final target population of older people is necessary. PMID:27092506

    The objective was to determine baseline characteristics of pediatric residency training programs and academic departments in regard to family-friendly work environments as outlined in the Report of the Task Force on Women in Pediatrics. We conducted Web-based anonymous surveys of 147 pediatric department chairs and 203 pediatric program directors. The chair's questionnaire asked about child care, lactation facilities, family leave policies, work-life balance, and tenure and promotion policies. The program director's questionnaire asked about family leave, parenting, work-life balance, and perceptions of "family-friendliness." The response rate was 52% for program directors and 51% for chairs. Nearly 60% of chairs reported some access to child care or provided assistance locating child care; however, in half of these departments, demand almost always exceeded supply. Lactation facilities were available to breastfeeding faculty in 74% of departments, although only 57% provided access to breast pumps. A total of 78% of chairs and 90% of program directors reported written maternity leave policies with slightly fewer reporting paternity leave policies. The majority (83%) of chairs reported availability of part-time employment, whereas only 27% of program directors offered part-time residency options. Most departments offered some flexibility in promotion and tenure. Although progress has been made, change still is needed in many areas in pediatric departments and training programs, including better accessibility to quality child care; improved lactation facilities for breastfeeding mothers; clear, written parental leave policies; and flexible work schedules to accommodate changing demands of family life.

    To present the technique and long-term results of retroperitoneal laparoscopic partial nephrectomy (LPN), focusing on the impact of an ergonomic platform. Between January 2000 and May 2016, 287 patients (193 men, 94 women) underwent LPN performed by four surgeons. The median (range) patient age was 59 (19-85) years, tumour size 3.1 (1-9) cm and PADUA score 7.3 (6-12). Access was retroperitoneal in 235 cases (82%). Since October 2010, we have used the ETHOS(™) chair (ETHOS(™) , Seattle, WA, USA) during excision of the tumour in 130 patients (45.3%). A total of 51 tumours (17.7%) were excised without ischaemia and 226 (78.7%) under warm ischaemia, with clamping of the renal artery using an enucleo-resection technique. We suture the resection bed and perform renorrhaphy using a barbed-suture pre-loaded with absorbable LAPRA-TY(™) clips (Ethicon, Somerville, NJ, USA). The impact of the ETHOS chair was examined using a matched-pair analysis (66 with ETHOS chair vs 67 without ETHOS chair). The median (range) operating time was 146 (60-325) min, the median (range) estimated blood loss was 99 (10-3 000) mL and the mean (range) warm ischaemia time (WIT) was 17.1 (7-47) min. Histology showed 240 (83.6%) renal cell carcinomas (RCCs) and 46 (15.9%) benign tumours. The cumulative overall disease-free survival rate after a median (range) follow-up of 84 (3-155) months was 100% for 203 pT1 RCCs and local recurrence was observed in one patient (0.4%), who was managed by radical nephrectomy. There were two conversions (0.7%) to open surgery, both to hand-assisted laparoscopy. Perirenal haematoma was observed in 13 patients (4.5%). A total of 20 patients (6.9%) required transfusions (2-11 units). We observed five urine leaks (1.7%) requiring prolonged drainage. The median (range) length of hospital stay was 5 (3-24) days. Three patients developed arteriovenous fistulas, which were successfully occluded by superselective embolization (1.0%). Use of the ETHOS chair resulted in

This situation presents a unique opportunity to utilize chair massage in addressing women's health in rural Ghana, particularly when it comes to muscle pain and fatigue from heavy labor. The objective of this case report is to determine the results of chair massage as a strategy to reduce neck, shoulder, and back pain, while increasing range of motion. The patient is a 63-year-old Ghanaian female, who was struck by a public transport van while carrying a 30-50 pound load on her head, two years prior. The accident resulted in a broken right humerus and soft tissue pain. A traditional medicine practitioner set the bone, however there was no post-accident rehabilitation available. At the time of referral, she presented complaints of shoulder, elbow, and wrist pain. In addition, she was unable to raise her right hand to her mouth for food intake. The results of this case report include an increase in range of motion, as well as elimination of pain in the right shoulder, elbow, and hand. Visual assessments showed an approximate increase of ROM within the ranges of 45-65 degrees in the right arm, as well as 10-15 degrees in 4th and 5th fingers. There was also a decrease in muscle hypertonicity in the thoracic and cervical areas, and a profound increase in quality of life for the patient. This case report illustrates how therapeutic chair massage was utilized to address a common health concern for one woman in rural Ghana. It also demonstrates that pre-existing musculoskeletal disorders and pain may be eliminated with massage intervention. Massage therapy may be important to ameliorating certain types of health problems in remote rural villages in low income countries.

    The objective of this prospective clinical study was to evaluate the clinical performance of chair-side generated monolithic lithium disilicate crowns after 72 months. Forty-one posterior full contour crowns made of lithium disilicate ceramic were inserted in 34 patients with a chair-side CAD/CAM technique. One crown per patient was randomly selected for evaluation at baseline, 6, 12, 24, 36, 48, 60 and 72 months according to the modified US Public Health Service criteria. After a mean examination time of 73.2 months (SD ± 1.7 months), 25 crowns were available for re-examination. Within the observation period, three failures occurred due to one crown fracture after 2.9 years, an abutment fracture after 6.0 years, and one severe endodontic problem after 6.1 years. One lithium disilicate crown showed a loss of retention after 2 years but could be reinserted. There were two events of caries below the crown margin, one after 24 and another one after 48 months. Both teeth received cervical adhesive composite fillings. Two abutment teeth changed their sensibility perception from positive to negative within the first 13 months. The failure-free rate was 87.6%, and the complication-free rate was 70.1% after 6 years according to the Kaplan-Meier analysis. Due to the fact that there was only one severe technical complication and the severe biological complications were in a normal range, the clinical performance of monolithic lithium disilicate crowns in the posterior region was completely satisfying. The chair-side application of monolithic lithium disilicate crowns can be recommended.

    The aim of the study were to demonstrate the possible hemodynamic changes and cerebral blood flow alterations in patients who were positioned from supine to beach chair position; and to detect if the position change causes any cortical activity alteration as measured by the 4-channeled electroencephalography monitor. 35 patients were included. Before the induction, mean arterial pressure and patient state index values were recorded (T0). After the intubation, doppler-ultrasonography of the patients' internal carotid and vertebral arteries were evaluated to acquire cerebral blood flow values from the formula. In supine position, mean arterial pressure, patient state index and cerebral blood flow values were recorded (T1) and the patient was positioned to beach chair position. After 5min all measurements were repeated (T2). Measurements of patient state index and mean arterial pressure were repeated after 20 (T3), and 40 (T4)min. There was a significant decrease between T0 and T1 in heart rate (80.5±11.6 vs. 75.9±14.4beats/min), MAP (105.8±21.9 vs. 78.9±18.4mmHg) and PSI (88.5±8.3 vs. 30.3±9.7) (all p<0.05). Mean arterial pressure decreased significantly after position change, and remained decreased, compared to T1. The overall analysis of patient state index values (T1-T4) showed no significant change; however, comparing only T1 and T2 resulted in a statically significant decrease in patient state index. There was a significant decrease in cerebral blood flow after beach chair position. Beach chair position was associated with a decrease in cerebral blood flow and patient state index values. Patient state index was affected by the gravitational change of the cerebral blood flow; however, both factors were not directly correlated to each other. Moreover, the decrease in patient state index value was transient and returned to normal values within 20min. Copyright © 2015 Sociedade Brasileira de Anestesiologia.

    Neuropraxia of the greater auricular nerve is an uncommon complication of shoulder surgery, with the patient in the beach chair position. The greater auricular nerve, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. In this case series, we present three cases of neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. We outline the risk of using devices of this nature and discourage the use of similar headrest devices due to the potential complications in headrest devices that exert pressure on the posterior auricular area to maintain head position during surgery.

  15. Advancing Women’s Health and Women’s Leadership With Endowed Chairs in Women’s Health

    Gender-based bias and conflation of gender and status are root causes of disparities in women’s health care and the slow advancement of women to leadership in academic medicine. More than a quarter of women physicians train in internal medicine (IM) and its subspecialties, and women physicians almost exclusively constitute the women’s health focus within IM. Thus, IM has considerable opportunity to develop women leaders in academic medicine and promote women’s health equity. To probe whether holding an endowed chair—which confers status—in women’s health may be an effective way to advance both women leaders in academic medicine and women’s health, the authors explored the current status of endowed chairs in women’s health in IM. They found that the number of these endowed chairs in North America increased from 7 in 2013 to 19 in 2015, and all were held by women. The perceptions of incumbents and other women’s health leaders supported the premise that an endowed chair in women’s health would increase women’s leadership, the institutional stature of women’s health, and activities in women’s health research, education, and clinical care. Going forward, it will be important to explore why not all recipients perceived that the endowed chair enhanced their own academic leadership, whether providing women’s health leaders with fundraising expertise fosters future success in increasing the number of women’s health endowed chairs, and how the conflation of gender and status play out (e.g., salary differences between endowed chairs) as the number of endowed chairs in women’s health increases.

    Chair-sitting may allow for more readily activated scalene, sternocleidomastoid, and parasternal intercostal muscles, and may raise and enlarge the upper thoracic cage, thereby allowing the thoracic cage to be more easily compressed. To evaluate the effect of chair-sitting during exercise training on respiratory muscle function in mechanically ventilated patients. We randomized 16 patients to a control group and 18 patients to a chair-sitting group. The patients in the chair-sitting group were transferred by 2 intensive care unit nurses from bed to armchair and rested for at least 30 min, based on the individual patient's tolerance. We measured heart rate, blood pressure, S(pO(2)), and respiratory rate. In the treatment group, before transferring the patient from bed to armchair, and 30 min after the completion of chair-sitting we measured respiratory muscle function variables, including the ratio of respiratory rate (f) to tidal volume (V(T)), S(pO(2)), maximum inspiratory pressure (P(Imax)) and maximum expiratory pressure (P(Emax)). In the control patients we took those same measurements while the patient was in semirecumbent position, before and after treatments, for at least 6 days or until the patient was discharged from the intensive care unit or died. The 2 groups did not significantly differ in age, sex, or clinical outcomes. Respiratory rate, V(T), f/V(T), S(pO(2)), P(Imax), and P(Emax) were not significantly better in the chair-sitting group. The study period significantly improved respiratory rate, V(T), P(Imax), and P(Emax) (all P < .001), but not f/V(T). Six days of chair-sitting exercise training did not significantly improve respiratory muscle function in mechanically ventilated patients.

    Total knee arthroplasty is effective to regain quality of life. Standing up from and sitting down on a chair and stair stepping motion are important in daily living. We previously reported in vivo kinematics of this implant during a stepping exercise. The purpose of this analysis was to assess in vivo knee motion during standing up from and sitting down on a chair and determine the motion pattern in patients with the unique knee prosthesis. A total of 15 patients implanted with Bi-Surface PS were assessed during standing up from and sitting down on a chair. The Bi-Surface PS knee is a posterior-cruciate substitute prosthesis with a unique ball-and-socket joint in the mid-posterior portion of the femoral and tibial components. Patients were examined during standing up from and sitting down on a chair using a two-dimensional to three-dimensional registration technique. During standing up from and sitting down on a chair from minimum to 30° knee flexion, anterior femoral translation was slight. From 30° knee flexion to maximum flexion, the kinematic pattern was a medial pivot and rollback. This study demonstrated that the knee motion kinematic patterns observed in this study were not similar to normal knee kinematics and derived from the unique design of the Bi-Surface PS.

    Chair rise performance is incorporated in clinical assessments to indicate fall risk status in older persons. This study investigated the test-retest reliability of a pendant-sensor-based assessment of chair rise performance. Forty-one older persons (28 females, 13 males, age: 72-94) were assessed in two sessions with 3 to 8 days in between. Repeated chair rise transfers were measured after different instructions. Relative and absolute test-retest reliability of chair rise measurements in individual tests and average over all tests were evaluated by means of intra-class correlation coefficients (ICCs) and standard error of measurement (SEM) as a percentage of the measurement mean. Systematic bias between the measurements in test and retest was examined with paired t-tests. Heteroscedasticity of the measurements was visually checked with Bland-Altman plots. In the different test conditions, the ICCs ranged between 0.63 and 0.93, and the SEM% ranged between 5.7% and 21.2%. The relative and absolute reliability of the average over all tests were ICC = 0.86 and SEM% = 9.5% for transfer duration, ICC = 0.93 and SEM% = 9.2% for maximum vertical acceleration, and ICC = 0.89 and SEM% = 10.0% for peak power. The results over all tests indicated that a fall risk assessment application based on pendant-worn-sensor measured chair rise performance in daily life might be feasible.

  19. The effect of overbooking on idle dental chair capacity in the Pretoria region of the Gauteng Oral Health Services.

    2012-09-01

    An analysis of annual reports revealed that on average 20% of patient appointments with oral hygienists in the Department of Health in the Pretoria region were not utilised due to patient noncompliance (i.e. broken appointments). Many solutions have been considered to address the high rate of noncompliance and the resulting idle chair capacity. One solution selected to overcome some of the negative consequences of broken appointments was deliberate overbooking. The aim of our study was to determine the effect of overbooking on idle dental chair capacity by measuring the utilisation rate over a three month period (July to September) after 25% overbooking was introduced in the Pretoria region. A statistical analysis was conducted on our results to determine an overbooking rate that would ensure full utilisation of the available dental chair capacity. The available time units over the three month study period amounted to 1365, allocated to 1427 patients resulting in an overal overbooking rate of 4.54%. The overall utilisation rate was found to be 79.2%. The calculated regression line estimated that there would be full utilisation of dental chair capacity at an overbooking rate of 26.7%. Overbooking at the levels applied in this study had a minimal overall effect on idle dental chair capacity. Our results confirm the need for careful planning and management in addressing noncompliance. In a manner similar to the clinical situation, organisational development requires a correct diagnosis in order that an appropriate and effective intervention may be designed.

  20. Organizing awareness and increasing emotion regulation: revising chair work in emotion-focused therapy for borderline personality disorder.

    PubMed

    Pos, Alberta E; Greenberg, Leslie S

    2012-02-01

    Emotion-focused therapy (EFT) is an empirically supported treatment that may have potential as a stage-two treatment for borderline personality disorder (BPD). Specific aspects of BPD--the tendency to experience fluctuating self-states; weakness in meta-cognitive or reflective functioning; and the tendency for self-states to be organized by presently occurring interpersonal processes--present challenges to applying some EFT interventions with this population. In particular, even within a highly attuned, validating and accepting empathic relationship, clients with BPD may have difficulty with the usual manualizations of chair work interventions. This is because these interventions often employ polarization and intensification of experience in order to activate adaptive alternate emotional resources and self organizations. For the client with borderline personality disorder, these interventions may be counter-productive, emotionally dysregulating and disorganizing. EFT chair work, however, also has the potential to provide structure to the borderline clients experience of self, to stimulate metacognitive awareness, provide an alive experience of the process of polarization, attenuate emotional activation, and increase the experience of self-coherence. This article describes the development of stepwise approximations of EFT two-chair intervention for self-critical splits. It outlines potential stages of two-chair work as well as intervention principles important for productive chair work with this population. The EFT change principles of awareness, expression regulation, reflection, transformation, and corrective experience still centrally apply. However, several additional strategies are discussed to scaffold clients' capacity to both experience and regulate emotion.

    Prevotella intermedia/nigrescens is one of the well-known pathogens causing periodontal diseases, and the red florescence excited by the visible blue light caused by the protoporphyrin IX in the bacterial cells could be useful for the chair-side detection. The aim of this study was to evaluated levels of periodontal pathogen, especially P. intermedia in clinical samples of red fluorescent dental plaque. Thirty two supra gingival plaque samples from six individuals were measured its fluorescence at 640nm wavelength excited by 409nm. Periodontopathic bacteria were counted by the Invader PLUS PCR assay. Co-relations the fluorescence intensity and bacterial counts were analyzed by Person's correlation coefficient and simple and multiple regression analysis. Positive and negative predictive values of the fluorescence intensities for with or without P. intermedia in supragingival plaque was calculated. When relative fluorescence unit (RFU) were logarithmic transformed, statistically significant linear relations between RFU and bacterial counts were obtained for P. intermedia, Porphyromonas gingivalis and Tannerella forsythia. By the multiple regression analysis, only P. intermedia had statistically significant co-relation with fluorescence intensities. All of the fluorescent dental plaque contained P. intermedia m. In contrast, 28% of non-fluorescent plaques contained P. intermedia. To check the fluorescence dental plaque in the oral cavity could be the simple chair-side screening of the mature dental plaque before examining the periodontal pathogens especially P. intermedia by the PCR method.

    This work has been developed in the Chair of Biology II, the curricular contents of which correspond to Human Anatomy. This subject is taught in the second semester of the second year of studies in Bioengineering. Our main objective is that the students attending the course may integrate the syllabus contents of Anatomy with those of other subjects in the career. Ever since 1998 we have organized a congress named Congreso Intracátedra de Biología II (Intra Chair Congress on Biology II). This is the last assignment in the semester and is compulsory for regular students of the subject. It consists in simulating a scientific congress with international characteristics. The guidelines for the congress are made known to the students at the beginning of the semester. In groups of up to three members, the students must undertake a work that relates aspects of Anatomy with Bioengineering. Students are expected to investigate on diagnostic and/or therapeutic technology in order to write a paper that must be accepted in advance of the event. The presentation of the work must be made through PowerPoint. The originality of the research work done and the wide range of topics selected are surprising. Problems are tackled from the standpoints both of the various medical fields and of bioengineering despite the fact that they are just students of the second year in Bioengineering.

    To identify the career development needs Vice Chair for Education in Surgery Departments (VCESDs). In all, 33 VCESDs were invited to complete an online survey to identify the scope of duties, scholarly activity, job satisfaction, and career development needs. A total of 29/33 (88%) VCESDs responded. Time constraints were the most frequent impediment for MDs vs. PhDs (p < 0.05). Dominant faculty development needs were conducting educational research (2.0 ± 0.78 for MDs, 1.33 ± 0.76 for PhDs), developing resident selection systems (1.68 ± 0.73), and mentorship programs (1.95 ± 0.77) for MDs, and developing teach the teacher programs (1 ± 0), and program performance evaluation systems (1.33 ± 0.76) for PhDs. The skills deemed to be of greatest importance were ability to communicate effectively (1.27 ± 0.55), resolve personnel conflicts (1.32 ± 0.57), and introduce change (1.41 ± 0.59). PhDs revealed a greater need to learn strategies for dealing with disruptive faculty (1.0 ± 0 vs 2.15 ± 0.87). This information will inform the future career development of VCESDs and will assist Department Chairs who wish to recruit and retain VCESDs.

    The aim of this study was to determine and verify the optimal location of the motion axis (MA) for the seat of a dynamic office chair. A dynamic seat that supports pelvic motion may improve physical well-being and decrease the risk of sitting-associated disorders. However, office work requires an undisturbed view on the work task, which means a stable position of the upper trunk and head. Current dynamic office chairs do not fulfill this need. Consequently, a dynamic seat was adapted to the physiological kinematics of the human spine. Three-dimensional motion tracking in free sitting helped determine the physiological MA of the spine in the frontal plane. Three dynamic seats with physiological, lower, and higher MA were compared in stable upper body posture (thorax inclination) and seat support of pelvic motion (dynamic fitting accuracy). Spinal kinematics during sitting and walking were compared. The physiological MA was at the level of the 11th thoracic vertebra, causing minimal thorax inclination and high dynamic fitting accuracy. Spinal motion in active sitting and walking was similar. The physiological MA of the seat allows considerable lateral flexion of the spine similar to walking with a stable upper body posture and a high seat support of pelvic motion. The physiological MA enables lateral flexion of the spine, similar to walking, without affecting stable upper body posture, thus allowing active sitting while focusing on work. © 2016, Human Factors and Ergonomics Society.

  5. Applying an empty-chair monologue paradigm to examine unresolved grief.

    Field, N P; Horowitz, M J

    1998-01-01

    In this study the Gestalt empty-chair technique was applied in a research context to assess unresolved grief and its relation to later adjustment. Bereaved individuals who experienced the death of a spouse on average 6 months ago participated in an empty-chair monologue task in which they were instructed to speak to their deceased spouse, imagining that they had one last opportunity to do so. They completed a questionnaire at the end of their monologue speech assessing their affective experience during the monologue. It contained items associated with unresolved grief (e.g., anger, guilt, helplessness, nonacceptance). Near the time of the monologue session, bereaved participants also completed the Beck Depression Inventory (BDI) (Beck and Steer 1987) and the Impact of Event Scale (IES) (Horowitz, Wilner, and Alvarez 1979). At 14 months postloss, bereaved participants again were administered the BDI and IES. As hypothesized, the extent of unresolved grief as assessed by the monologue questionnaire at 6 months postloss was predictive of 14-month postloss symptoms, even when statistically controlling for 6-month postloss symptoms in hierarchical regression analyses.

    The number of graduates of U.S. dental schools enrolled in U.S. postdoctoral programs in periodontics has been decreasing. The aims of this study were to determine the perspectives of periodontics department chairs regarding 1) features of a school's predoctoral curriculum that promote student interest in advanced periodontal education and 2) characteristics of a periodontal residency program that make it more attractive to dental students over other specialty programs. In 2015, a 14-question survey was designed and sent to chairs of periodontics departments at all 65 U.S. dental schools at the time. Questions addressed number of instructional hours; specialty clinic rotations; elective courses; number of applicants to periodontal residency; existence of a residency program; length of the residency program; and externships, fellowships, and financial stipends offered. The survey response rate was 73.8%. The results showed that departments offering more than seven clinical credit hours in periodontics to predoctoral students had the greatest number of residency applicants. Most of the applicants were from institutions that offered specialty clinic rotations, elective courses, and residency programs in periodontics. The number of applicants did not change significantly if a stipend or fellowship was offered. However, the availability of an externship was significantly associated with a greater number of applicants (p=0.042). These results suggest that offering periodontal clinical rotations, elective courses, and especially externships in periodontics during predoctoral education may encourage more graduating students to pursue postdoctoral periodontal education.

  7. Are pressure measurements effective in the assessment of office chair comfort/discomfort? A review.

    PubMed

    Zemp, Roland; Taylor, William R; Lorenzetti, Silvio

    2015-05-01

    Nowadays, the majority of jobs in the western world involves sitting in an office chair. As a result, a comfortable and supported sitting position is essential for employees. In the literature, various objective methods (e.g. pressure measurements, measurements of posture, EMG etc.) have been used to assess sitting comfort/discomfort, but their validity remains unknown. This review therefore examines the relationship between subjective comfort/discomfort and pressure measurements while sitting in office chairs. The literature search resulted in eight papers that met all our requirements. Four studies identified a relationship between subjective comfort/discomfort and pressure distribution parameters (including correlations of up to r = 0.7 ± 0.13). However, the technique for evaluating subjective comfort/discomfort seems to play an important role on the results achieved, therefore placing their validity into question. The peak pressure on the seat pan, the pressure distribution on the backrest and the pressure pattern changes (seat pan and backrest) all appear to be reliable measures for quantifying comfort or discomfort.

    We developed nonintrusive methods for simultaneous electrocardiogram, photoplethysmogram, and ballistocardiogram measurements that do not require direct contact between instruments and bare skin. These methods were applied to the design of a diagnostic chair for unconstrained heart rate and blood pressure monitoring purposes. Our methods were operationalized through capacitively coupled electrodes installed in the chair back that include high-input impedance amplifiers, and conductive textiles installed in the seat for capacitive driven-right-leg circuit configuration that is capable of recording electrocardiogram information through clothing. Photoplethysmograms were measured through clothing using seat mounted sensors with specially designed amplifier circuits that vary in light intensity according to clothing type. Ballistocardiograms were recorded using a film type transducer material, polyvinylidenefluoride (PVDF), which was installed beneath the seat cover. By simultaneously measuring signals, beat-to-beat heart rates could be monitored even when electrocardiograms were not recorded due to movement artifacts. Beat-to-beat blood pressure was also monitored using unconstrained measurements of pulse arrival time and other physiological parameters, and our experimental results indicated that the estimated blood pressure tended to coincide with actual blood pressure measurements. This study demonstrates the feasibility of our method and device for biological signal monitoring through clothing for unconstrained long-term daily health monitoring that does not require user awareness and is not limited by physical activity.

    Objective The aim of this study was to determine and verify the optimal location of the motion axis (MA) for the seat of a dynamic office chair. Background A dynamic seat that supports pelvic motion may improve physical well-being and decrease the risk of sitting-associated disorders. However, office work requires an undisturbed view on the work task, which means a stable position of the upper trunk and head. Current dynamic office chairs do not fulfill this need. Consequently, a dynamic seat was adapted to the physiological kinematics of the human spine. Method Three-dimensional motion tracking in free sitting helped determine the physiological MA of the spine in the frontal plane. Three dynamic seats with physiological, lower, and higher MA were compared in stable upper body posture (thorax inclination) and seat support of pelvic motion (dynamic fitting accuracy). Spinal kinematics during sitting and walking were compared. Results The physiological MA was at the level of the 11th thoracic vertebra, causing minimal thorax inclination and high dynamic fitting accuracy. Spinal motion in active sitting and walking was similar. Conclusion The physiological MA of the seat allows considerable lateral flexion of the spine similar to walking with a stable upper body posture and a high seat support of pelvic motion. Application The physiological MA enables lateral flexion of the spine, similar to walking, without affecting stable upper body posture, thus allowing active sitting while focusing on work.

    Prolonged sitting can cause health problems and musculoskeletal discomfort. There is a need for objective and non-obstructive means of measuring sitting behavior. A 'smart' office chair can monitor sitting behavior and provide tactile feedback, aiming to improve sitting behavior. This study aimed to investigate the effect of the feedback signal on sitting behavior and musculoskeletal discomfort. In a 12-week prospective cohort study (ABCB design) among office workers (n = 45) was measured sitting duration and posture, feedback signals and musculoskeletal discomfort. Between the study phases, small changes were observed in mean sitting duration, posture and discomfort. After turning off the feedback signal, a slight increase in sitting duration was observed (10 min, p = 0.04), a slight decrease in optimally supported posture (2.8%, p < 0.01), and musculoskeletal discomfort (0.8, p < 0.01) was observed. We conclude that the 'smart' chair is able to monitor the sitting behavior, the feedback signal, however, led to small or insignificant changes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The number of 4th-year medical student applications to the field of diagnostic radiology has decreased from 2009 to 2015. The purpose of this study was to learn how radiology departments are recruiting medical students. An anonymous online survey hyperlink was distributed to the members of the Society of Chairs of Academic Radiology Departments regarding both innovative and proven recruitment strategies. The results were synthesized with a recently published survey of medical students about factors influencing them to go into radiology. Forty of 126 radiology departments completed the survey. Most felt that radiology exposure and curricula require alteration given recent downward trends in medical student applications. A majority (79%) had changed their outreach to medical students in response to these trends. The responding department chairs felt that interactive learning while on rotation was the most important strategy for recruitment. The presence of a diversity program, dedicated medical school educator, or rotating daily assignment for students did not affect the likelihood of filling residency spots in the main match. Many radiology departments are changing their outreach to medical students to improve recruitment. Effective strategies to focus on include early active outreach by involving students in the radiology department, thereby framing radiologists as clinicians.

    A dental appointment commonly prompts fear of a painful experience, yet we have never fully understood how our brains react to the expectation of imminent tooth pain once in a dental chair. In our study, 21 patients with hypersensitive teeth were tested using nonpainful and painful stimuli in a clinical setting. Subjects were tested in a dental chair using functional near-infrared spectroscopy to measure cortical activity during a stepwise cold stimulation of a hypersensitive tooth, as well as nonpainful control stimulation on the same tooth. Patients' sensory-discriminative and emotional-cognitive cortical regions were studied through the transition of a neutral to a painful stimulation. In the putative somatosensory cortex contralateral to the stimulus, 2 well-defined hemodynamic peaks were detected in the homuncular orofacial region: the first peak during the nonpainful phase and a second peak after the pain threshold was reached. Moreover, in the upper-left and lower-right prefrontal cortices, there was a significant active hemodynamic response in only the first phase, before the pain. Subsequently, the same prefrontal cortical areas deactivated after a painful experience had been reached. Our study indicates for the first time that pain perception and expectation elicit different hemodynamic cortical responses in a dental clinical setting. © International & American Associations for Dental Research 2015.

    During the nineteenth century, many captains' wives from New England took up residence on the ships their husbands commanded. This article focuses on how those women at sea attempted to use material culture to domesticate their voyaging space. While writing in their journals, they referred to not only the small personal things such as books and knitting needles that they brought in their trunks, but also large items, built for and used by women, such as gamming chairs, deckhouses, parlor organs, sewing machines, and gimballed beds. Mary Brewster attempted to retreat from the ship's officers in her small deckhouse, Annie Brassey slept in the gimballed bed, and Lucy Lord Howes disembarked in a gamming chair when captured by Confederates during the Civil War. Evidence of these artifacts found during shipwreck archaeology could be used to further what is known of the culture aboard ships on which women lived. Analysis of the material culture reveals how a captain's wife domesticated space, altered her environment, and made a home on the ship for her family.

    Lever-drive wheelchairs lower physical strain but are less maneuverable than push-rim wheelchairs. Here, we study a possible solution in which the user simultaneously actuates clutches mounted between the levers and wheels each stroke via a clutch handle attached to one lever; this solution is of particular interest for user groups with only one functional hand. First, to demonstrate maneuverability, we show how this "yoked clutch" allows an experienced user to maneuver a constrained space. Then, we compared the difficulty of learning a yoked clutch chair to a conventional lever-drive transmission (i.e. a one-way bearing). Twenty-two unimpaired novice adults navigated a figure-eight track during six training sessions over two weeks. Participant mean speed improved roughly 60% for both chairs, with similar exponential improvement time constants (3 days) and final speeds. However, speed improvement mostly took place overnight rather than within the session for hand-clutching, and the physiological cost index was also about 40% higher. These results indicate that while hand-clutching is no more difficult to learn than a lever-drive, it is reliant on overnight improvement. Also, its increased maneuverability comes with decreased efficiency. We discuss how the yoked clutch may be particularly well suited for individuals with stroke during inpatient rehabilitation.

    Under a stretching force, the sugar ring of polysaccharide molecules switches from the chair to the boat-like or inverted chair conformation. This conformational change can be observed by stretching single polysaccharide molecules with an atomic force microscope. In those early experiments, the molecules were stretched at a constant rate while the resulting force changed over wide ranges. However, because the rings undergo force-dependent transitions, an experimental arrangement where the force is the free variable introduces an undesirable level of complexity in the results. Here we demonstrate the use of force-ramp atomic force microscopy to capture the conformational changes in single polysaccharide molecules. Force-ramp atomic force microscopy readily captures the ring transitions under conditions where the entropic elasticity of the molecule is separated from its conformational transitions, enabling a quantitative analysis of the data with a simple two-state model. This analysis directly provides the physico-chemical characteristics of the ring transitions such as the width of the energy barrier, the relative energy of the conformers, and their enthalpic elasticity. Our experiments enhance the ability of single-molecule force spectroscopy to make high-resolution measurements of the conformations of single polysaccharide molecules under a stretching force, making an important addition to polysaccharide spectroscopy.

    A present massage chair realizes the massage motion and force designed by a professional masseur. However, appropriate massage force to the user can not be provided by the massage chair in such a method. On the other hand, the professional masseur can realize an appropriate massage force to more than one patient, because, the masseur considers the physical condition of the patient. Our research proposed the intelligent massage system of applying masseur's procedure for the massage chair using estimated skin elasticity and DB to relate skin elasticity and massage force. However, proposed system has a problem that DB does not adjust to unknown user, because user's feeling by massage can not be estimated. Then, this paper proposed the estimation method of comfortable/uncomfortable feeling based on EEG using the neural network and k-means algorithm. The realizability of the proposed method is verified by the experimental works.

    High chairs are commonly used to feed children after 6 months. Related injuries are oftentime minor and rarely leading to death. We describe a case of a 2-year-old female child who used to jump alone on her high chair and also had the habit to fasten the straps by herself. Her mother found her hanging by the waist straps. A thorough investigation showed that she climbed her high chair and fastened the waist straps but not the crotch one. The girl slid down into the seat, trapping her neck in the waist straps and thus resulting in hanging. In here, we concluded that the victim's death was caused by asphyxia, itself, caused by accidental hanging. The present case is of a special interest because of the rare similar cases reported. This case suggests that a correct restraint use and a close supervision would have prevented such a fatal issue.

    Electronic educational (e-learning) technology usage continues to grow. Many medical journals operate companion blogs (an application of e-learning technology) that enable rapid dissemination of scientific knowledge and discourse. Faculty members participating in promotion and tenure academic tracks spend valuable time and effort contributing, editing, and directing these medical journal blogs. We sought to understand whether chairs of medicine and pediatric departments acknowledge blog authorship as academic achievement. The authors surveyed 267 chairs of US and Canadian medicine and pediatric departments regarding their attitudes toward the role of faculty participation in e-learning and blogging in the promotion and tenure process. The survey completion rate was 22.8% (61/267). A majority of respondents (87%, 53/61) viewed educational scholarship as either important or very important for promotion. However, only 23% (14/61) perceived importance to faculty effort in producing content for journal-based blogs. If faculty were to participate in blog authorship, 72% (44/61) of surveyed chairs favored involvement in a journal-based versus a society-based or a personal (nonaffiliated) blog. We identified a "favorable group" of chairs (19/59, 32%), who rated leadership roles in e-learning tools as important or very important, and an "unfavorable group" of chairs (40/59, 68%), who rated leadership roles in e-learning tools as somewhat important or not important. The favorable group were more likely to be aware of faculty bloggers within their departments (58%, 11/19 vs 25%, 10/40), viewed serving on editorial boards of e-learning tools more favorably (79%, 15/19 vs 31%, 12/39), and were more likely to value effort spent contributing to journal-based blogs (53%, 10/19 vs 10%, 4/40). Our findings demonstrate that although the majority of department chairs value educational scholarship, only a minority perceive value in faculty blogging effort.

    To determine problems associated with electric-powered indoor/outdoor wheelchairs (EPIOCs) and the benefits perceived by their users. Hospital-based cohort study of all patients referred over a 19-month period. Regional Wheelchair Service for North West London serving nine district wheelchair services. Of the 174 subjects referred, 10 withdrew their application or were found to be unsuitable at screening, 164 were assessed and 124 were prescribed chairs. One hundred and thirteen subjects were interviewed by telephone four months after provision of the chair. Demographic and diagnostic data; current chair usage; self-reported accidents and component faults were compared with those recorded in the unit records; new activities embarked on since delivery; and benefits reported for main carers. Seventeen 'mishaps' were reported by 15 users including tipping from chairs (6) and falls during transfers (3). Three probably reflected mechanical failure. Component failure was found in 39% of EPIOCs, mostly affecting control boxes (22), frames (10) and footrests (10). New activities were undertaken by 56 (50%) users, usually shopping and visits to friends/family. Eighty-five per cent of users felt that the chairs made life easier for their informal carers through increased independence, reducing transfers and reduced need for 'pushing'. The component failures and self-reported accidents (some potentially dangerous) have implications for the NHS, manufacturers, prescribers and users. EPIOCs enhance the independence of severely physically disabled individuals in the community and assist carers by lessening dependence and enhancing social interaction. This study demonstrated the need for follow-up of EPIOC users and chairs.

    Neurons in a restricted zone in the precentral gyrus of macaque monkeys respond to tactile, visual, and auditory stimuli. The tactile receptive fields of these multimodal cells are usually located on the face, arm, or upper torso. In the present study, in awake monkeys sitting in a primate chair, the neurons responded to a tactile probe touching the skin within the tactile receptive field. However, the same neurons did not respond when the tactile receptive field was touched by the primate chair, to which the monkey was habituated.
