The aim of the study was to report the epidemiological profile of HIV-1 positive patients from, Istanbul, Turkey, which has one of the lowest HIV-1/AIDS prevalences in Europe. The patients were followed by ACTHIV-IST group which was established by the Infectious Diseases Departments of five teaching hospitals (three university hospitals and two public hospitals) in Istanbul, Turkey. The HIV-1 positive patients were added to the standard patient files in all of the centers; these files were then transferred to the ACTHIV-IST database in the Internet. A total of 829 naiv-untreated HIV-1 positive patients were chosen from the database. The number of male patients was 700 (84.4%) and the mean age of the patients was 37 years (range, 17-79). In our study group 348 (42%) of the patients were married and 318 (38.7%) of the patients were single. The probable route of transmission was heterosexual intercourse in 437 (52.7%) patients and homosexual intercourse in 256 (30.9%) patients. In 519 (62.6%) patients the diagnose was made due to a screening test and in 241 (29.1%) patients, the diagnose was made due to an HIV-related/non-related disease. The mean CD4+ T cell number in 788 of the patients was 357.8/mm(3) (±271.1), and the median viral load in 698 of the patients was 100,000 copies/mL (20-9,790,000). In Turkey, the number of HIV-1 positive patients is still low and to diagnose with a screening test is the most common way of diagnostic route.

To compare clinical manifestations and activity of Behçet syndrome (BS) in the United States versus Turkey using validated outcome measures. Consecutive patients with BS from the US National Institutes of Health (NIH), New York University, and the University of Istanbul were evaluated. Disease activity was measured using the Behçet's Syndrome Activity Scale (BSAS) and the Behçet's Disease Current Activity Form (BDCAF) with quality of life measured by the Behçet Disease Quality of Life (BDQOL) form. One-way ANOVA, t-tests, and multivariate regression analyses were performed. Mean age did not differ between sites; however, more women were seen in the United States versus in Turkey (p < 0.001), and disease duration was longer in the United States (p = 0.02). Organ manifestations were similar for oral and genital ulcers, skin disease, arthralgia, eye disease, and thrombosis. However, more gastrointestinal (p < 0.001) and neurologic disease (p = 0.003) was seen in the United States. BSAS and BDCAF scores were worse in the United States compared to Turkey (p = 0.013 and < 0.001, respectively). Worse mean BDQOL scores were observed at the NIH compared to Istanbul (not significant). Multivariable regression models showed worse scores in ethnically atypical patients for BSAS and BDCAF (p = 0.04 and p = 0.001), American patients for BDCAF (p = 0.01), older age for BDCAF (p = 0.005), and women for BDQOL (p = 0.01). Demographic and clinical manifestations of BS differ between sites with higher disease activity in the United States compared to Turkey. Referral patterns, age, sex, ethnicity, and country of origin may be important in these differences. These observations raise the question of whether pathogenic mechanisms differ in Turkish and American patients.

2017-06-14

This cross-sectional study aimed to assess interpretation of symptoms as a cause of delays in patients with acute myocardial infarction (AMI). It was conducted at a university hospital in Istanbul, Turkey. The sample included 93 patients: 73 male, mean age 57.89 (12.13) years. Prehospital delay time ranged from 15 minutes to 10 days, with a median of 2 hours (interquartile range: 9.50). Patients waited for pain to go away (48.4%) and tried to calm down (39.8%). Most patients attributed AMI-related symptoms to a reason other than heart disease. In a multivariate logistic regression analysis, the type of AMI was classified based on electrocardiography findings (odds ratio 5.18, 95% confidence interval: 1.69-15.91, P=0.004) and was independently associated with a long prehospital delay time, indicating that patients with ST segment elevation MI would seek early medical care. Misinterpretation of symptoms and misconceptions about emergency treatment during AMI cause delays in admission and may affect treatment.

During the 17 years from 1962 to 1979, 4403 closed mitral commissurotomies were performed at the Istanbul Thoracic Surgery Center in Istanbul, Turkey. There were 60 hospital deaths (1.36%), 30 cerebral emboli (0.68%), 14 peripheral emboli (0.31%), five instances of severe mitral regurgitation (0.11%) and improvement of at least one New York Heart Association Class level in 92.2% of the patients available for late follow-up 1 to 17 years later (mean 4.2 years). Closed mitral commissurotomy without cardiopulmonary bypass can be a safe and effective alternative to open mitral commissurotomy where circumstances dictate its use. PMID:15226845

To compare 4 year undergraduate nursing students' educational needs concerning disaster preparedness and response in Istanbul and Miyazaki. This was a 13 question descriptive/comparative survey. Females, aged 18-22 years, and in their second year of their nursing programs, rarely participate in disaster preparedness and response courses at their universities (75.2%) or outside (89.8%). Educational needs of Miyazaki's students who had already participated in these courses (85%) were higher than in Istanbul's (67.2%). Of those whose educational needs had not been met, 55.9% were considering taking another lecture/course in one of the following years (Istanbul, 47.4%; Miyazaki, 71.4%). The majority of students from Istanbul reported some knowledge about disaster preparedness and response from courses at their universities while Miyazaki's students showed less. Effective teaching methods/resources were mock drills. Nursing interventions in disaster situations in "response competencies" were preferred issues to be included in course content (Istanbul, 90.4%; Miyazaki, 93.1%). Most student nurses had no expectations on skills that could be gained from a disaster preparedness and response course/culture of disaster lecture (Istanbul, 48.7%; Miyazaki, 34.5%). Nursing students in both cities seem more likely to participate in disaster preparedness and response courses/lectures. The present study also addresses the need to incorporate mass casualty care and disaster management skills into undergraduate curricula. Core contents for nursing curricula in both cities need to be continued. Outcome competencies must be identified and validated through further research. © 2013 The Authors.

Turkish Compulsory Earthquake Insurance and "Istanbul Earthquake

NASA Astrophysics Data System (ADS)

Durukal, E.; Sesetyan, K.; Erdik, M.

2009-04-01

The city of Istanbul will likely experience substantial direct and indirect losses as a result of a future large (M=7+) earthquake with an annual probability of occurrence of about 2%. This paper dwells on the expected building losses in terms of probable maximum and average annualized losses and discusses the results from the perspective of the compulsory earthquake insurance scheme operational in the country. The TCIP system is essentially designed to operate in Turkey with sufficient penetration to enable the accumulation of funds in the pool. Today, with only 20% national penetration, and about approximately one-half of all policies in highly earthquake prone areas (one-third in Istanbul) the system exhibits signs of adverse selection, inadequate premium structure and insufficient funding. Our findings indicate that the national compulsory earthquake insurance pool in Turkey will face difficulties in covering incurring building losses in Istanbul in the occurrence of a large earthquake. The annualized earthquake losses in Istanbul are between 140-300 million. Even if we assume that the deductible is raised to 15%, the earthquake losses that need to be paid after a large earthquake in Istanbul will be at about 2.5 Billion, somewhat above the current capacity of the TCIP. Thus, a modification to the system for the insured in Istanbul (or Marmara region) is necessary. This may mean an increase in the premia and deductible rates, purchase of larger re-insurance covers and development of a claim processing system. Also, to avoid adverse selection, the penetration rates elsewhere in Turkey need to be increased substantially. A better model would be introduction of parametric insurance for Istanbul. By such a model the losses will not be indemnified, however will be directly calculated on the basis of indexed ground motion levels and damages. The immediate improvement of a parametric insurance model over the existing one will be the elimination of the claim processing period, which would certainly be a major difficulty for the expected low-frequency/high intensity loss case of Istanbul.

This study was conducted to determine the prevalence and distribution of urogenital Chlamydia trachomatis genotypes in symptomatic male patients who were referred to the clinics of the Istanbul Faculty of Medicine. Of 419 urogenital swabs, 57 samples (13.6 %) were positive for C. trachomatis . Genotype distribution of C. trachomatis -positive samples identified five genetic variants namely genotype E as the most prevalent (36.4 %), followed by genotype G (23.6 %), H (21.8 %), D (16.4 %) and F (1.8 %). We believe that this is the first study on distribution of genotypes of C. trachomatis genital infections in symptomatic men in Istanbul, Turkey.

Death is the most severe consequence of violence against women. The purpose of this study was to determine the frequency of violence-related deaths among women and the general characteristics of fatal violence cases against women in Istanbul, Turkey. A total of 20,486 forensic autopsies performed between 2006 and 2010, in Istanbul, were retrospectively analyzed. Of these, 537 violence-related deaths among women were included in the study. The victims were investigated in terms of sociodemographic characteristics, exposed type of violence, and autopsy findings. Out of all female deaths (n = 4165), 12.9% were due to violence against women, which comprised 2.6% of all autopsies (n = 20,456) performed during the study period in Istanbul. The median age of the victims was 43 years, and a significant proportion of victims (49.7%) were between the ages of 21 and 40 years. The deaths occurred most commonly in private residences (51.2%, n = 275), whereas the street was the crime scene for 14.5% (n = 78) of cases. Firearm injuries (50.1%, n = 269) were the most common cause of death, followed by stab wounds (28.3%, n = 152) and strangulation (8.4%, n = 45). Among the identified perpetrators, 52.3% were victims' spouses or boyfriends. The perpetrators were female in 4.4% (n = 16) of cases. Istanbul is the most important and cosmopolitan city of Turkey, representing the country's cultural characteristics. Therefore, the data obtained in this study may be strong indicators of violence against women in Turkey. Copyright © 2016 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Turkey is seeing a steady rise in rates of HIV infection in the country. The number of individuals with HIV/AIDS was greater than 7000 in 2014 according to data released by the Ministry of Health, and heterosexual contacts were reported to be the main transmission routes. Istanbul has the highest number of reported cases of HIV infection. The aim of the study was to determine the prevalence of HIV-1 drug resistance in 50 heterosexual patients from Istanbul. The most prevalent subtype was found to be subtype B (56.2 %). Resistance-associated mutations were found in 14 patients with 6/14 patients being therapy-experienced and 8/14 therapy naive at the time point of analysis. With increasing number of patients who require treatment and the rapid up-scaling of the antiretroviral therapy in Turkey, HIV-1 drug resistance testing is recommended before starting treatment in order to achieve better clinical outcomes.

Bustling Istanbul, with its magnificent historical heritage, has spanned the divide between Europe and Asia for more than 2,500 years. Originally called Byzantium, the city was founded in the 7th century BC on the Golden Horn, an arm of the narrow Bosporus (also spelled Bosphorus) Strait, which connects the Sea of Marmara to the south, with the Black Sea to the north. Constantine I made it his capital of the Eastern Roman Empire in AD 330. As Constantinople, the strategically located city arose as the preeminent cultural, religious, and political center of the Western world. It reached the height of its wealth and glory in the early 5th century. After centuries of decline, the city entered another period of tremendous growth and prosperity when, as Istanbul, it became the capital of the Turkish Ottoman Empire in 1457. Although Turkey moved its capital to Ankara in 1923, Istanbul remains the nation's largest city with a population of over 8 million, its commercial center, and a major port. Two bridges spanning the Bosporus, and ships in the busy channel can be seen on the enlargement. On the image, the water areas have been replaced with a thermal image: colder waters are displayed in dark blue, warmer areas in light blue. Note the dark lines showing boat wakes, and the cold water entering the Sea of Marmara from deeper waters of the Bosporus. http://photojournal.jpl.nasa.gov/catalog/PIA02665

Abstract A total of 167 ticks collected from humans in Istanbul (Turkey) in 2006 were screened for Rickettsia species, and nested PCRs targeting gltA and ompA rickettsial fragment genes were carried out. Rickettsia monacensis (51), R. aeschlimannii (8), R. conorii subsp. conorii (3), R. helvetica (2), R. raoultii (1), R. africae (1), R. felis (1), and other Rickettsia spp. (2), were detected. To our knowledge, these Rickettsia species (except R. conorii) had never been reported in ticks removed from humans in Turkey. The presence of R. africae also had not been previously described, either in Hyalomma ticks or in any European tick species. In addition, R. aeschlimannii and R. felis had not been found associated with Rhipicephalus bursa specimens. The presence of human pathogenic Rickettsia in ticks removed from humans provides information about the risk of tick-borne rickettsioses in Turkey. PMID:22925016

The analyses address the following research questions: (1) Do Turkish diabetics in Germany and Turkey differ in terms of quality of life? (2) If yes, can these differences (in part) be explained by social factors (age, gender, education, household size), functional limitations and availability of support? (3) Are social factors, functional limitations and availability of support differently associated with quality of life among Turkish diabetics in Germany and Turkey? For this comparative cross-sectional study, 111 patients with type 2 diabetes were personally interviewed in Istanbul (Turkey) and 294 Turkish patients in Hamburg (Germany). For quality of life measurement we have used the Turkish version of the WHOQOL-Bref-26. Sociodemographics included age, sex, education and household-size. Health related functional limitations were assessed on the basis of an index of (instrumental) activities of daily living including the availability of help. Statistical analyses were conducted on group comparisons with Chi-square- and T-tests as well as linear regressions. There are no significant differences between Turkish diabetics in Germany and Turkey in the physical and the psychological dimensions of the WHOQOL-Bref. However, in the WHOQOL-domains 'social QoL' and 'environmental QoL' Turkish diabetics living in Hamburg have a significantly better quality of life than their counterparts in Istanbul. These differences cannot be explained by individual sociodemographic factors, functional limitations and availability of support. Furthermore, we found much stronger positive associations between education and quality of life in Istanbul than in Hamburg. Beyond strong similarities between the two samples in sociodemographics, physical and mental health the social and environmental quality of life was significantly assessed better by the Turkish diabetics living in Hamburg. This is most likely an effect of public investment in social security, infrastructure and health care which is also influencing the decision as to where to spend life in retirement.

Post-Seismic Crustal Deformation Following The 1999 Izmit Earthquake, Western Part Of North Anatolian Fault Zone, Turkey

NASA Astrophysics Data System (ADS)

Gurkan, O.; Ozener, H.

2004-12-01

The North Anatolian Fault is an about 1500 km long, extending from the Karliova to the North Aegean. Turkey is a natural laboratory with high tectonic activity caused by the relative motion of the Eurasian, Arabian and Anatolian plates. Western part of Turkey and its vicinity is a seismically active area. Since 1972 crustal deformation has been observed by various kinds of geodetic measurements in the area. Three GPS networks were installed in this region by Geodesy Department of Kandilli Observatory and Earthquake Research Institute( KOERI ) of Bogazici University: (1) Iznik Network, installed on the Iznik-Mekece fault zone, seismically low active part, (2) Sapanca Network, installed on the Izmit-Sapanca fault zone, seismically active part, (3) Akyazi Network, installed on their intersection area, the Mudurnu fault zone. First period observations were performed by using terrestrial methods in 1990 and these observations were repeated annually until 1993. Since 1994, GPS measurements have been carried out at the temporary and permanent points in the area and the crustal movements are being monitored. Horizontal deformations, which have not been detected by terrestrial methods, were determined from the results of GPS measurements. A M=7.4 earthquake hit Izmit, northern Turkey, on August 17, 1999. After this earthquake many investigations have been started in the region. An international project has been performed with the collaboration of Massachussets Institute of Technology, Turkish General Command of Mapping, Istanbul Technical University, TUBITAK-Marmara Research Center and Geodesy Department of KOERI. Postseismic movements have been observed by the region-wide network. A GPS network including 49 well spread points in Marmara region was observed twice a year between 1999 and 2003 years. During these surveys, another network with 6 points has been formed by using 2 points from each 3 microgeodetic networks on NAFZ with appropriate coverage and geometry. These points have been connected by GPS observations to monitor the deformations. This expanded microgeodetic network has been occupied with Istanbul-Kandilli continuous GPS station (KANT). The objective of this paper is to present the post-seismic crustal deformation obtained from the GPS observations at the Western Part of the North Anatolian Fault (NAF) in Turkey.

After centuries of decline, the city entered another period of tremendous growth and prosperity when, as Istanbul, it became the capital of the Turkish Ottoman Empire in 1457. Although Turkey moved its capital to Ankara in 1923, Istanbul remains the nation's largest city with a population of over 8 million, its commercial center, and a major port. Two bridges spanning the Bosporus, and ships in the busy channel can be seen. Image courtesy ASTER science team.

Resilience of coastal utilities after earthquakes and tsunamis has major importance for efficient and proper rescue and recovery operations soon after the disasters. Vulnerability assessment of coastal areas under extreme events has major importance for preparedness and development of mitigation strategies. The Sea of Marmara has experienced numerous earthquakes as well as associated tsunamis. There are variety of coastal facilities such as ports, small craft harbors, and terminals for maritime transportation, water front roads and business centers mainly at North Coast of Marmara Sea in megacity Istanbul. A detailed vulnerability analysis for Yenikapi region and a detailed resilience analysis for Haydarpasa port in Istanbul have been studied in previously by Cankaya et al., (2015) and Aytore et al., (2015) in SATREPS project. In this study, the methodology of vulnerability analysis under tsunami attack given in Cankaya et al., (2015) is modified and applied to Bakirkoy district of Istanbul. Bakirkoy district is located at western part of Istanbul and faces to the North Coast of Marmara Sea from 28.77oE to 28.89oE. High resolution spatial dataset of Istanbul Metropolitan Municipality (IMM) is used and analyzed. The bathymetry and topography database and the spatial dataset containing all buildings/structures/infrastructures in the district are collated and utilized for tsunami numerical modeling and following vulnerability analysis. The tsunami parameters from deterministically defined worst case scenarios are computed from the simulations using tsunami numerical model NAMI DANCE. The vulnerability assessment parameters in the district according to vulnerability and resilience are defined; and scored by implementation of a GIS based TVA with appropriate MCDA methods. The risk level is computed using tsunami intensity (level of flow depth from simulations) and TVA results at every location in Bakirkoy district. The preliminary results are presented and discussed.

This study aimed to understand nursing practice environment characteristics in Istanbul-area hospitals in Turkey, the relationship between these characteristics, nurse burnout levels and nurses' intentions to leave work. A well-known relationship exists in many countries between nursing practice environments and nurse burnout and intention to leave work. However, little is known about the relationship between practice environment characteristics and nursing outcomes in Turkey. This cross-sectional study was conducted among 2592 nurses in 20 Ministry of Health and 29 private hospitals in Istanbul, Turkey. A demographic questionnaire, Practice Environment Scale of the Nursing Work Index and Maslach Burnout Inventory were used for data collection. Almost half of nurses suffered from high-level burnout related to emotional exhaustion and personal accomplishment, and one-third reported depersonalization and the intent to leave their jobs within a year. A poor nursing practice environment was the leading factor, increasing nurses' burnout levels in all subdimensions. Burnout related to emotional exhaustion, personal accomplishment and poor practice environment increased intention to leave. Permanent positions decreased intention. There was a relationship between poor practice environments and nursing outcomes in Turkey. The use of a survey data collection method is a potential study limitation. Quantitative and qualitative methods could be combined to obtain more detailed objective data about nursing practice environments. Poor practice environments, high-level burnout and intention to leave work are significant problems in Istanbul, Turkey. Favourable practice environments and job security should be provided to improve nursing outcomes. Policymakers and nurse managers should be aware of any negative issues regarding nursing practice environments and job security to improve nursing outcomes. © 2016 International Council of Nurses.

Although a decreasing trend of tuberculosis (TB) was reported in Turkey, higher proportion of extrapulmonary tuberculosis (EPT) was revealed. In this retrospective study, clinical and laboratory data of 141 EPT patients were evaluated for a seven-year period by using descriptive statistics, and parametric and non-parametric tests where appropriate. The most frequent types of EPT were meningeal TB (23%) and TB lymphadenitis (21%), respectively. Other types of EPT were skeletal, miliary, peritoneal, abscess, genitourinarial, cutaneous and gastrointestinal involvement which ranged between 18% and 1%. Mean age was 42 and female/male ratio was almost equal. All patients were born in Turkey. Although all of them were permanent residents of Istanbul, 73% of the patients came from East and Southeast Region of Turkey. For the patients, being older than 40 years old (p<0.01), having miliary TB (p<0.05) and high CRP levels (p<0.05) were found to be associated with mortality. EPT still remains as a significant morbidity and mortality reason in lower income populations and developing countries. In our study, although all patients were residents of Istanbul approximately two thirds of them have migrated from East and Southeast parts of the country. The relatively high prevalence of tuberculosis cases in Istanbul may be due to the permanent migration from other parts of the country. Early diagnosis and initiation of appropriate treatment are the keys for reducing morbidity and mortality in patients with EPT, particularly in the cases of older ages. © 2013.

Istanbul (Turkey) is located on the west edge of North Anatolia Fault and hence is an earthquake prone city with a population that exceeds 15 million people. In addition, the city is still growing as center of commerce, tourism and culture that increases the exposure more and more. During the last decade, although Istanbul grew faster than ever in its history, precautions against a possible earthquake have also increased steadily. The two big earthquakes (in Kocaeli and Duzce Provinces) occurred in 1999 alongside Istanbul and these events became the trigger events that accelerated the disaster risk reduction activities in Istanbul. Following a loss estimation study carried out by Japanese International Cooperation Agency (JICA) in 2001 and Istanbul Earthquake Master Plan prepared by four major universities' researchers in 2003; it was evaluated that understanding and analyzing the geological structure in Istanbul was the main concern. Thereafter Istanbul Metropolitan Municipality's Directorate of Earthquake and Ground Research (DEGRE) carried out two major geo-scientific studies called "microzonation studies" covering 650 km2 of Istanbul's urbanized areas between 2006 and 2009. The studies were called "microzonation" because the analysis resolution was as dense as 250m grids and included various assessments on hazards such as ground shaking, liquefaction, karstification, landslide, flooding, and surface faulting. After the evaluation of geological, geotechnical and geophysical measurements; Earthquake and Tsunami Hazard Maps for all Istanbul, slope, engineering geology, ground water level, faulting, ground shaking, inundation, shear wave velocity and soil classification maps for the project areas were obtained. In the end "Land Suitability Maps" are derived from the combination of inputs using multi-hazard approach. As a result, microzonation is tool for risk oriented urban planning; consisting of interdisciplinary multi-hazard risk analyses. The outputs of microzonation are used in land development/use plans, hazard identification in urban transformation, determination of the routes and characteristics of various types of engineering structures such as highways, tunnels, bridges, railroads, viaducts and ports. Hence, by the use of detailed geo-scientific analyses, basics of earthquake resilient urbanization is guaranteed.

In the last decade, the importance of high-precise geoid determination at local or national level has been pointed out by Turkish National Geodesy Commission. The Commission has also put objective of modernization of national height system of Turkey to the agenda. Meanwhile several projects have been realized in recent years. In Istanbul city, a GNSS/Levelling geoid was defined in 2005 for the metropolitan area of the city with an accuracy of ±3.5cm. In order to achieve a better accuracy in this area, "Local Geoid Determination with Integration of GNSS/Levelling and Astro-Geodetic Data" project has been conducted in Istanbul Technical University and Bogazici University KOERI since January 2016. The project is funded by The Scientific and Technological Research Council of Turkey. With the scope of the project, modernization studies of Digital Zenith Camera System are being carried on in terms of hardware components and software development. Accentuated subjects are the star catalogues, and centroiding algorithm used to identify the stars on the zenithal star field. During the test observations of Digital Zenith Camera System performed between 2013-2016, final results were calculated using the PSF method for star centroiding, and the second USNO CCD Astrograph Catalogue (UCAC2) for the reference star positions. This study aims to investigate the position accuracy of the star images by comparing different centroiding algorithms and available star catalogs used in astro-geodetic observations conducted with the digital zenith camera system.

OSYM is the main institute for organizing the national level large scale exams in Turkey. According to the Ministry of National Education of Turkey data, there are 17.588.958 students in the country. Therefore, OSYM has a significant role for everyone from every level of education. More than 15% of the total students are studying in Istanbul. These students have various exams throughout a year, which brings some procedures for each exam to be applied. OSYM Coordination Offices were founded to meet the demands and procedures of these exams and applicants. There are 9 Coordination Offices in Istanbul. Moreover, OSYM Application Centers were founded as support units to OSYM Coordination Offices. These units are under the high schools. There are 67 OSYM Application Centers in Istanbul. In the study, spatial distribution of OSYM Coordination Offices and OSYM Application Centers in Istanbul have been studied related to the transportation network of each district of Istanbul city. Origin Destination Cost Matrix (ODCM) and Invers Distance Weighting (IDW) Method were used to visualize the distribution of OSYM Coordination Offices and Application Centers accessibilities. ODCM measures the nearest paths along the transportation network from origins to destinations. IDW is one of the several interpolation methods allocating values to unknown points. ODCM Method was used to calculate the distances over the transportation network. The results obtained from ODCM Method were used in IDW Method to interpolate the weightings of the OSYM offices and centers. Accessibility of the OSYM Coordination Offices and Application Centers has been detected according to surrounding transportation network. Spatial distribution of existing offices and application centers were evaluated by districts of Istanbul city in conclusion of the study by the ODCM and IDW Methods.

The increasing amount of solid waste arising from municipalities and other sources and its consequent disposal has been one of the major environmental problems in Turkey. Istanbul is a metropolitan city with a current population of around 14 million, and produces about 9000 ton of solid waste every day. The waste composition for Istanbul has changed markedly from 1981 to 1996 with large decreases in waste density, much of which is related to decreased amounts of ash collected in winter. In recent years, the Istanbul region has implemented a new solid waste management system with transfer stations, sanitary landfills, andmore » methane recovery, which has led to major improvements. In the Black Sea region of Turkey, most of the municipal and industrial solid wastes, mixed with hospital and hazardous wastes, are dumped on the nearest lowlands and river valleys or into the sea. The impact of riverside and seashore dumping of solid wastes adds significantly to problems arising from sewage and industry on the Black Sea coast. Appropriate integrated solid waste management systems are needed here as well; however, they have been more difficult to implement than in Istanbul because of more difficult topography, weaker administrative structures, and the lower incomes of the inhabitants.« less

OBJECTIVE: Childbirth is a natural physiological event experienced by many women; however, it is frequently also a source of fear in women. Rates of cesarean sections in Turkey are higher in the urban areas than in the rural areas. We hypothesized that lower fear of childbirth (FOC) rates would be observed in the city having the lowest cesarean section rates in Turkey. This study aimed to compare FOC in women in two resident populations: one in a rural area and the other in an urban area. METHODS: This study was conducted on 253 pregnant women in Istanbul, a large urban municipality, and Siirt, a city in rural Turkey. A descriptive information form and the A version of the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) were used. RESULTS: Severe FOC levels were recorded in women in the Istanbul sample; moreover, these levels were higher than those recorded in women in the Siirt sample. In addition, women in the Istanbul sample preferred vaginal birth to cesarean section and had greater FOC, a finding which demonstrates that women prefer vaginal birth even though they have a higher FOC level and live in a city with high cesarean section rates. Where women live (rural versus urban areas) affects their perception of birth and consequently, their FOC levels. CONCLUSION: The results of this study suggest that further cross-cultural and regional research is needed for better understanding FOC and factors associated with elevated FOC levels within each cultural setting.

Turkey, with a population of 75 million, is located at the confluence of Europe and Asia. Istanbul is at the hearth of Turkey's fast economic growth. The city has an annual growth of 3.7% and, according to a study conducted by OECD, is ranked 12th among 45 OECD metro-regions. Istanbul generates 27% of Turkey's Gross Domestic Product (GDP); 40% of tax revenues; and 38% of total industrial output (OECD, 2008). As a result, Istanbul is facing a variety of challenging environmental problems affecting more than 15 million people. Observations show that the number of days exceeding the 24-hour limit value of 50 μgm-3 reached 157 in 2008, with a significant increase from previous years. The city is also a hot spot of pollutant emissions for the surrounding Eastern Mediterranean area. As part of the CityZEN project, in order to quantify the contribution of this megacity as a source of air pollution in the Eastern Mediterranean, a climatological trajectory analysis using a regional climate model output (RegCM3) and a high resolution regional modeling study were performed using the Models-3 WRF meteorological and CMAQ air quality models. Trajectory approach was used to identify the effects of Istanbul emissions on other cities in regional scale. A 30-year (1961-1990) period RegCM3 simulations were used to get a meaningful evaluation. The trajectories were computed according to a method described by Pettersen (1956) as a forward trajectory approach in a 27-km grid resolution. An air parcel was released once every 6h and a total of 42,368 air parcels (trajectories) were released during these 30 years. Long-term meteorological observations in Istanbul show northeasterly and southwesterly prevailing winds over the city. According to these prevailing winds, the distributions of trajectories were mainly observed from the north and south directions of the city. In order to run an air quality model, anthropogenic emission inventory was compiled from a number of different sources including high resolution emission inventories developed for Istanbul at 2km resolution and at 10 km resolution emission inventory of INERIS covering Europe. MOSESS model was used to process emissions data to provide CMAQ ready data (i.e., speciated and vertically and temporally distributed). Regional biogenic and dust emissions are calculated at each time step using the online MEGAN and GOCART modules of WRF-CHEM model. This paper focuses on the climatological and air quality model outputs to analyze the possible impacts of Istanbul emissions on regional air quality.

In 1983, abortion without restriction as to reason was legalized in Turkey. However, at an international conference in 2012, the Prime Minister condemned abortion and announced his intent to draft restrictive abortion legislation. As a result of public outcry and protests, the law was not enacted, but media reports suggest that barriers to abortion access have since worsened. We aimed to conduct a qualitative study exploring women's recent abortion experiences in Istanbul, Turkey. In 2015, we conducted 14 semi-structured in-depth interviews with women aged 18 or older who had obtained abortion care in Istanbul on/after January 1, 2009. We employed a multimodal recruitment strategy and analyzed these interviews for content and themes using deductive and inductive techniques. Women reported on a total of 19 abortions. Although abortion care is available in private facilities, only one public hospital provides abortion services without restriction as to reason. Women who had multiple abortions in different facility types described quality of care more positively in the private sector. Unmarried women considered their marital status when making the decision to seek an abortion and reported challenges obtaining comprehensive sexual and reproductive health services. All participants were familiar with the Turkish government's antiabortion discourse and believed that this was reflective of an overarching desire to restrict women's rights. Public abortion services in Istanbul are currently limited, and private abortion services are accessible but relatively expensive to obtain. Recent antiabortion political rhetoric appears to have negatively impacted access and service quality. This is the first qualitative study exploring women's experiences obtaining abortion services in Turkey since the proposed abortion restriction in 2012. Further research exploring the experiences of unmarried women and abortion accessibility in other regions of the country is warranted. Copyright © 2017 Elsevier Inc. All rights reserved.

Assessing the effect of wind speed/direction changes on urban heat island intensity of Istanbul. Perim Temizöz, Deniz H. Diren, Cemre Yürük and Yurdanur S. Ünal Istanbul Technical University, Department of Meteorological Engineering, Maslak, Istanbul, Turkey City or metropolitan areas are significantly warmer than the outlying rural areas since the urban fabrics and artificial surfaces which have different radiative, thermal and aerodynamic features alter the surface energy balance, interact with the regional circulation and introduce anthropogenic sensible heat and moisture into the atmosphere. The temperature contrast between urban and rural areas is most prominent during nighttime since heat is absorbed by day and emitted by night. The intensity of the urban heat island (UHI) vary considerably depending on the prevailent meteorological conditions and the characteristics of the region. Even though urban areas cover a small fraction of Earth, their climate has greater impact on the world's population. Over half of the world population lives in the cities and it is expected to rise within the coming decades. Today almost one fifth of the Turkey's population resides in Istanbul with the percentage expected to increase due to the greater job opportunities compared to the other cities. Its population has been increased from 2 millions to 14 millions since 1960s. Eventually, the city has been expanded tremendously within the last half century, shifting the landscape from vegetation to built up areas. The observations of the last fifty years over Istanbul show that the UHI is most pronounced during summer season. The seasonal temperature differences between urban and suburban sites reach up to 3 K and roughly haft degree increase in UHI intensity is observed after 2000. In this study, we explore the possible range of heat load and distribution over Istanbul for different prevailing wind conditions by using the non-hydrostatic MUKLIMO3 model developed by DWD (Deutscher Wetterdienst). The study is focused on the spatial gradients of temperature, humidity and winds during summer. The model run by the average temperature and humidity vertical profiles over Istanbul during summer season with 200 m resolution. A series of sensitivity tests are carried out for different wind speeds (1-5 m/sec) and prevailing wind directions. Land use data are created by combining the geographical data obtained from Istanbul Metropolitan Municipality and CORINE Land Cover Raster Data. The land use table involves 25 land use types. The residential areas are classified considering the percentage of the building coverages and the average height of the buildings within the grid cell. The associated parameters in land use table of MUCLIM3 are modified accordingly. Simulations show that the urban model MUCLIM3 is able to capture typical observed characteristics of urban climate of Istanbul qualitatively. The UHI effect at night is stronger at low wind speeds, depending on the two competing factors: reduced cold advection from outlying rural areas and the magnitude of the sensible heat flux over cities which offsets the reduced advective cooling. The preliminary results of the sensitivity tests are discussed by concentrating on the changes of the hot spots in Istanbul, the diurnal cycle range over different land use types at different reference levels of 5m, 30m and 50m, and the vertical profile of the meteorological variables in relation to the sea-breeze circulation. This work is funded by the ERAfrica Project LOCLIM3 and TUBITAK with the Grant Number 114Y047.

Ogan, Feral

The purposes of this study were to identify the in-service needs of high school science teachers in Istanbul, Turkey according to the subgroups such as school type and gender and determine the priority obstacles preventing these science teachers from attendance at in-service programs. Moreover, this study aimed to find the other greatest needs of high school science teachers that are not mentioned in the survey instrument. The data for this research was gathered by conducting a survey in Istanbul, Turkey in Fall 2001 and Spring 2002 Semesters. Turkish translation of the modified version of a science teacher's needs inventory, Science Teacher Inventory of Need (STIN), entitled STIN-2 was used as the survey instrument. The subjects consisted of 75 high school science teachers who were selected from 369 high schools by using stratified random sampling in grades nine through eleven. By personally administering the survey, 422 science teachers from 75 high schools completed the survey and a 97% response rate was achieved. The results obtained in this study show that Turkish high school science teachers in Istanbul have a number of shared needs. One other indication is that they also have a number of needs, which are specific to subgroups of those science teachers.

2010-06-01

The objective of the present study was to assess changes in land use/land cover patterns in the coastal town of Silivri, a part of greater Istanbul administratively. In the assessment, remotely sensed data, in the form of satellite images, and geographic information systems were used. Types of land use/land cover were designated as the percentage of the total area studied. Results calculated from the satellite data for land cover classification were compared successfully with the database Coordination of Information on the Environment (CORINE). This served as a reference to appraise the reliability of the study presented here. The CORINE Program was established by the European Commission to create a harmonized Geographical Information System on the state of the environment in the European Community. Unplanned urbanization is causing land use changes mainly in developing countries such as Turkey. This situation in Turkey is frequently observed in the city of Istanbul. There are only a few studies of land use-land cover changes which provide an integrated assessment of the biophysical and societal causes and consequences of environmental degradation in Istanbul. The research area comprised greater Silivri Town which is situated by the coast of Marmara Sea, and it is located approximately 60 km west of Istanbul. The city of Istanbul is one of the largest metropolises in Europe with ca. 15 million inhabitants. Additionally, greater Silivri is located near the terminal point of the state highway connecting Istanbul with Europe. Measuring of changes occurring in land use would help control future planning of settlements; hence, it is of importance for the Greater Silivri and Silivri Town. Following our evaluations, coastal zone of Silivri was classified into the land use groups of artificial surfaces agricultural areas and forests and seminatural areas with 47.1%, 12.66%, and 22.62%, respectively.

Tsunami Loss Assessment For Istanbul

Tsunami risk and loss assessment incorporating with the inundation mapping in Istanbul and the Marmara Sea region are presented in this study. The city of Istanbul is under the threat of earthquakes expected to originate from the Main Marmara branch of North Anatolian Fault System. In the Marmara region the earthquake hazard reached very high levels with 2% annual probability of occurrence of a magnitude 7+ earthquake on the Main Marmara Fault. Istanbul is the biggest city of Marmara region as well as of Turkey with its almost 12 million inhabitants. It is home to 40% of the industrial facilities in Turkey and operates as the financial and trade hub of the country. Past earthquakes have evidenced that the structural reliability of residential and industrial buildings, as well as that of lifelines including port and harbor structures in the country is questionable. These facts make the management of earthquake risks imperative for the reduction of physical and socio-economic losses. The level of expected tsunami hazard in Istanbul is low as compared to earthquake hazard. Yet the assets at risk along the shores of the city make a thorough assessment of tsunami risk imperative. Important residential and industrial centres exist along the shores of the Marmara Sea. Particularly along the northern and eastern shores we see an uninterrupted settlement pattern with industries, businesses, commercial centres and ports and harbours in between. Following the inundation maps resulting from deterministic and probabilistic tsunami hazard analyses, vulnerability and risk analyses are presented and the socio-economic losses are estimated. This study is part of EU-supported FP6 project ‘TRANSFER'.

Sudden ionospheric disturbances (SID) are the enhanced electron density structures in the D region ionosphere which occur in response to the increase in X-ray flares and EUV flux. SIDs can be monitored using Very Low Frequency (VLF) radio signals (3-30 kHz) which travel between the D-region and the surface of the Earth. In this study, we use SID monitors obtained from the Stanford University Solar Center and two antennas which were built at the Istanbul Technical University to track the ionospheric disturbances in the VLF range. Our antennas are capable of capturing signals from several VLF transmitting stations. In this work, we focus on the variations in the signal strength of the closest VLF transmitting station 'TBB' which is operating at 26.7 kHz frequency at BAFA, Turkey (37.43N, 27.15E). We present ITU SID observations from both antennas; show the daily variation, general structure and the typical patterns we observe as well as case studies of significant events. Our initial analysis shows close relationship between observed X-ray flares from geosynchronous GOES 13 and GOES 15 satellites and VLF station signal strength received by the monitors.

One of the main requirements during post disaster recovery operations is to maintain proper transportation and fluent communication at the disaster areas. Ports and harbors are the main transportation hubs which must work with proper performance at all times especially after the disasters. Resilience of coastal utilities after earthquakes and tsunamis have major importance for efficient and proper rescue and recovery operations soon after the disasters. Istanbul is a mega city with its various coastal utilities located at the north coast of the Sea of Marmara. At Yenikapi region of Istanbul, there are critical coastal utilities and vulnerable coastal structures and critical activities occur daily. Fishery ports, commercial ports, small craft harbors, passenger terminals of intercity maritime transportation, water front commercial and/or recreational structures are some of the examples of coastal utilization which are vulnerable against marine disasters. Therefore their vulnerability under tsunami or any other marine hazard to Yenikapi region of Istanbul is an important issue. In this study, a methodology of vulnerability analysis under tsunami attack is proposed with the applications to Yenikapi region. In the study, high resolution (1m) GIS database of Istanbul Metropolitan Municipality (IMM) is used and analyzed by using GIS implementation. The bathymetry and topography database and the vector dataset containing all buildings/structures/infrastructures in the study area are obtained for tsunami numerical modeling for the study area. GIS based tsunami vulnerability assessment is conducted by applying the Multi-criteria Decision Making Analysis (MCDA). The tsunami parameters from deterministically defined worst case scenarios are computed from the simulations using tsunami numerical model NAMI DANCE. The vulnerability parameters in the region due to two different classifications i) vulnerability of buildings/structures and ii) vulnerability of (human) evacuation are defined and scored. The risk level is computed using tsunami intensity (level of flow depth from simulations) and vulnerability (structural and human-based) at each node in Yenikapi. The results are presented at high resolution (1m) and discussed.

In 2013, an airborne laser scan survey was conducted in the territory of the Ionian city of Kolophon near the western coast of modern Turkey as part of an archaeological survey project carried out by the Mimar Sinan University of Istanbul (Turkey) and the University of Vienna (Austria). Several light detection and ranging (LiDAR) studies have been carried out in the temperate climate zones of Europe, but only a few in Mediterranean landscapes. Our study is based on the first LiDAR survey carried out for an archaeological purpose in Turkey and one of the first in the Mediterranean that have been planned, measured and filtered especially for archaeological research questions. The interpretation of LiDAR data combined with ground-observations proved extremely useful for the detection and documentation of archaeological remains below Mediterranean evergreen vegetation and dense maquis. This article deals with the methodological aspects of interpreting LiDAR data, using the Kolophon data as a case study. We offer a discussion of the strengths and limitations of LiDAR as an archaeological remote sensing method and suggest a best practice model for interpreting LiDAR data in a Mediterranean context. © 2017 The Authors.

High population density and intense industrial activity has resulted in various forms of pollution in megacities. Air pollution ranks at the top of this list. This study investigated long-term changes in air pollutant parameters (SO(2), CO, NO, NO(2), NO(x)) in Istanbul City, Turkey, using data from air-quality measurement stations on the Asian and European sides of Istanbul. The results show decreases from 2002 to 2010 in the amounts of SO(2) (one of the main pollutants released as a result of the burning of fossil fuels) and CO (indicative of incomplete combustion). However, NO(x) concentrations showed fluctuations over time, rather than a steady decline throughout the study period.

Sahip, Yusuf; Turan, Janet Molzan

2007-11-01

Worldwide, there is increasing recognition that if family and reproductive health programmes are to be successful, the involvement of men is essential. As part of the problem, men also have to be seen as part of the solution. The reality is that in many countries, including Turkey, men generally do not accompany their partners to health facilities for family planning, antenatal and postnatal services and are not expected to attend the labour or birth of their child. Workplace programmes are a potential strategy for meeting the reproductive health education needs of men in industrial cities such as Istanbul. This intervention study was developed to test the feasibility and effects of expanding a special programme for expectant fathers to large workplaces in Istanbul, with the aim of improving the health of Turkish families during the pregnancy, birth and newborn periods. The findings indicate that it is possible to train workplace physicians in Istanbul to conduct regular educational programmes for expectant fathers on reproductive health, and that such programmes may have beneficial effects, especially in the areas of pregnancy nutrition, exclusive breast-feeding, and support behaviours. Considering the difficulty of getting men to attend hospital or clinic-based educational programmes in large urban areas, bringing such training programmes to men at their places of work has the potential to be an important strategy. Given that large workplaces in Turkey already have full-time physicians charged with the duty of health education for employees, this is also a feasible strategy.

As healthcare professionals, nursing educators need to be prepared to manage and deliver care in what are often dangerous conditions. This research aims to determine and compare nursing educators' perceptions of disaster preparedness and response (DP&R) in Istanbul and Miyazaki. An 18 question descriptive questionnaire was used. One hundred and forty-four nursing educators representing two state university nursing schools in Istanbul, Turkey, and one state and two private universities in Miyazaki, Japan were enrolled. Educators had an average age of 40 years and had been educators for 1-15 years. Just over half of the participants had basic knowledge regarding DP&R with most of them considering taking special courses in the future. The majority considered "caregiver" as a role they could undertake in a disaster situation. The existence of major concerns and conflicts in disaster responses were low. The top ranked item was in the area of conflict between family and job responsibilities. Age and academic levels showed significant differences in basic knowledge on DP&R. Regardless of knowledge in this subject area, no statistical significance on personal preparedness or being a volunteer to disaster events was found. Nursing educators were not thinking about what kinds of disasters occur in the areas where they currently teach and were underprepared to deal with disaster situations. To improve the perceptions of the nursing educators on DP&R, mass casualty care and disaster management skills need to be incorporated into formal education and training on disaster preparedness and workplace preparedness. © 2014 The Authors.

There are very limited data characterizing the epidemiology of anaphylaxis from low- and middle-income country settings. We aimed to estimate the frequency of anaphylaxis admissions to hospitals in Istanbul. We obtained data from all 45 hospitals in Istanbul over a 12-month period and used ICD-10 codes to extract data on those admitted with a recorded primary diagnosis of anaphylaxis. Because of concerns about possible under-coding, we undertook an additional analysis to identify patients admitted with two or more clinical codes for symptoms and/or signs suggestive of, but not coded as having, anaphylaxis. A total of 114 cases (79 people with anaphylaxis codes and 35 with symptoms and signs suggestive of anaphylaxis) were identified, giving an overall estimate of 1.95 cases per 100 000 person-years. The novel two-stage identification approach employed suggests significant under-recording of anaphylaxis in those admitted to hospitals in Istanbul. © 2012 John Wiley & Sons A/S.

Non-suicidal self-harm behavior (SHB), which is a pervasive and dangerous problem, is frequent among adolescents and it is important to evaluate the associated psychological and social factors to better understand its nature and to plan treatment programs. Aim of the present study is to determine the prevalence of SHB and the associated variables such as substance use, psychological, behavioral and social factors among 10th-grade students in Istanbul/Turkey. Cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul/Turkey. A representative sample of 4957 10th-grade students was studied between October 2012 and December 2012. SHB within the previous year were reported by 14.4% of the students (n = 713). Lifetime suicidal thoughts or behavior, tobacco, alcohol and/or drug use, symptoms of depression, anxiety and impulsive, delinquent and aggressive behaviors were also associated with SHB in Turkish 10th-grade students. The findings of the present study may be relevant in prevention and management of SHB as well as important problems among students, such as substance use, impulsive, delinquent, aggressive and suicidal behavior.

Aim To compare the quality of the 2008 cancer mortality data of the Istanbul Directorate of Cemeteries (IDC) with the 2008 data of International Agency for Research on Cancer (IARC) and Turkish Statistical Institute (TUIK), and discuss the suitability of using this databank for estimations of cancer mortality in the future. Methods We used 2008 and 2010 death records of the IDC and compared it to TUIK and IARC data. Results According to the WHO statistics, in Turkey in 2008 there were 67 255 estimated cancer deaths. As the population of Turkey was 71 517 100, the cancer mortality rate was 9.4 per 10 000. According to the IDC statistics, the cancer mortality rate in Istanbul in 2008 was 5.97 per 10 000. Conclusion IDC estimates were higher than WHO estimates probably because WHO bases its estimates on a sample group and because of the restrictions of IDC data collection method. Death certificates could be a reliable and accurate data source for mortality statistics if the problems of data collection are solved. PMID:23100210

Twice in the past 1000 years a sequence of damaging earthquakes has propagated over a period of a few decades along the North Anatolian Fault (NAF) in Turkey towards Istanbul, with the final earthquake in the sequence catastrophically damaging the city. This occurred most recently in 1509, causing 10,000 casualties in a population of about 200,000. The population is now 20 million, the building stock more fragile, and the last earthquake of the current sequence is considered imminent. Since July 2014, UNAVCO has installed 2 EarthScope borehole geophysical instrument strings, which include Gladwin Tensor strainmeters and passive, short-period 3-component seismometers, into boreholes provided by internationally supported Geophysical Observatory at the North Anatolian Fault (GONAF) and Bogazici University Kandilli Observatory. Funding for instruments and staff participation was provided by NSF. If the project remains on schedule, we anticipate that 4 additional BSM strings will be installed by the fall 2015. Our joint international project gives an opportunity to enhance the detection capability of a suite of deep seismometers (GONAF) installed near Istanbul and will permit us to image dynamic rupture along the NAF and to monitor and better understand the tectonic processes leading to failure. The tectonic and geodynamic environment of the NAF near Istanbul in many ways resembles the San Andreas Fault setting of San Francisco; these instruments will enhance the ability to monitor ultra-slow process near the probable source zone of the Mw>7 earthquake beneath the Marmara Sea on the NAF This project has provided UNAVCO an opportunity to gain experience in strainmeters installations outside of North America. The techniques developed to adapt to the challenges of installing borehole strainmeters on islands and other remote locations with limited resources will greatly enhance our ability to install these BSM instruments in similar locations in the future.

An Extreme Hailstorm on 27 July 2017 in Istanbul, Turkey: Synoptic Scale Circulation and Thermodynamic Evaluation

2018-03-01

During the afternoon hours of July 27, 2017, an extreme hailstorm struck the most populated city of Turkey, Istanbul. This rapidly growing supercell which produces large hail led to numerous injuries and damaged automobiles, houses, aircrafts, crops, and infrastructure of the city. As a result of the movement of the cut-off cyclone from Middle East to western Turkey, warm air advection penetrated over Marmara, and the land surface temperature of Istanbul reached 34 °C (5 °C above the mean). The transport of significant amount of moisture, which was caused by excessive heating of Marmara Sea surface temperatures (24.9 °C), to the low levels of the atmosphere by strong southwesterly winds enabled the increase of low-level moisture convergence. Both abnormal temperature differences between land and 500-hPa level (41.5 °C) and excessive wind shear values (20.3 m/s) between surface and 6 km above ground level (AGL) increased the thermal instability and updraft conditions of the baroclinic atmosphere. This condition resulted in thunderstorms, stormy and gale wind gusts (31.9 m/s 15:20 UTC), extreme lightning activity (totally 2696 cloud-to-ground and 5791 intracloud), large hailstones between 3-6 cm diameter and high hourly precipitation amounts (38.7, 36.2, 29.8, and 27.2 mm in Sisli, Kadikoy, Uskudar, and Fatih regions, respectively, between 14:00 and 15:00 UTC) in the urban settlements of the city. The stability indices, Showalter, K, Total of totals, SWEAT, and CAPE also showed the high probability of severe thunderstorm occurrence over Istanbul. Based on a comparison among these five indices, the SWEAT index is most appropriate to represent the atmospheric conditions over the city owing to low-level moisture, warm air advection, and low and mid-level wind speed terms in its equation.

Background: Rate of coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) varies in different countries. This may be attributable to common transmission routes as well as social, economic, and cultural factors. Objectives: The purpose of this study was to investigate the prevalence and risk factors of HCV infection among HIV-positive patients in Istanbul, Turkey. Patients and Methods: Since January 2006 to November 2013, 949 HIV-positive patients that were enrolled in this study by ACTHIV-IST (Action Against HIV in Istanbul) Study Group, which consists of five centers to follow up HIV-positive patients in Istanbul. Epidemiologic and clinical data were collected retrospectively from medical records and were transferred to an HIV database system. Results: Among 949 patients, 84% were men and the mean age was 37.92 ± 11.54 years (range, 17-79). The most frequent route of transmission was heterosexual intercourse (48.8%), followed by men having sex with men (30.5%). Only nine patients (0.9%) had history of injection drug use (IDU). The prevalence of HIV/HCV coinfection was 0.9% (9:949). The IDU rate was 44.4% (4:9) in patients with HIV/HCV coinfection (three of them were not Turkish citizens), whereas this rate was only 0.6% (5:881) in patients with only HIV infection (P < 0.01). Genotypes 1b, 2a/2c, and 3 were determined in five, one, and two patients, respectively. Genotype could not be determined in one patient. History of residence in a foreign country (P < 0.01) and imprisonment (P < 0.01) were also considered as risk factors in terms of HIV/HCV coinfection. Conclusions: Prevalence of HIV/HCV coinfection is considerably low in Turkey. The extremely rare prevalence of IDU might have a role in this low prevalence. PMID:25337142

Blank cartridge guns are generally regarded as being harmless and are not considered to be firearms in the legal sense in most countries. To show the danger of these guns upon simple modifications, we report 59 fatalities resulting from these simply modified blank cartridge guns in Istanbul, Turkey. The great majority of the victims were males and the age of those ranged from 11 to 61 years. In 55.9% of these cases, homicide was the origin followed by suicide (39%). The right temporal region was detected to be the preferred region in suicidal shots by blank cartridge guns with a frequency of 56.5%. In trial shots, all these guns were detected to discharge steel or lead spherical objects, generally 4 or 5 mm in diameter, successfully. Our findings strongly suggest that these guns should also be considered as handguns in the legal sense.

Toxic metal (Hg, Cd, Pb, Cu and Zn) concentrations of small-medium bluefish, anchovy and sardine in Istanbul, Turkey, were determined using inductively coupled plasma-mass spectrometry (ICP-MS) throughout 1 year. The concentrations of pollutants were found to vary according to season and species. Estimates of weekly intake levels of the metals were calculated and compared to recommended safe limits for fish consumption by humans. The levels of Cd, Pb, Cu and Zn in the fillets of all species resulted in estimates of weekly intake levels that were lower than the recommended safe limits. The concentrations of Hg of small bluefish in September, of medium bluefish in June and September, of anchovy in March, and of sardine in August and September resulted in estimates of weekly intake levels that were higher than the recommended safe limits for human consumption.

Our aim was to evaluate the SPT results of asthmatic children according to age and gender, in Istanbul and its neighborhood, followed for a period of 16 years. Consecutive 5080 asthmatic children, aged 1 to 18 years, admitted to Pediatric Allergy Policlinics of Istanbul University Cerrahpasa Medicine Faculty from 1987 to 2003, were screened retrospectively for 10 frequently exposed allergens. 3086 cases (61 %) had SPT reactivity for one and/or for multiple allergens; the SPT reactivity percentages of the exposed allergens was 50 % (2554 cases) for house dust mites DP, 49 % (2462 cases) for house dust mites DF, 15 % (784 cases) for cat dander, 10 % (525 cases) for dog dander, 4 % (228 cases) for lamb wool, 10 % (504 cases) for wheat, 3 % (162 cases) for egg white, 6 % (345 cases) for hazelnut pollen, 6 % (318 cases) for Candida Albicans, 6 % (326 cases) for Aspergillus Fumigatus. While house dust mites were determined as the predominant allergen for each age groups in this study, allergy against cat dander was the third important allergen in sequence, as cat is a domestic pet which is frequently kept at home in Turkey.

Few studies about compulsive buying consider the economic framing situation. This study is concerned with the impact of different economic environments - the crisis in Greece vs. the boom in Turkey - on compulsive buying tendencies of students, while taking the role of gender and available money into account. Compulsive buying was measured by a Greek and Turkish translation of the German Compulsive Buying Scale (Raab, Neuner, Reisch & Scherhorn, 2005) in Greece and Turkey, which enabled an identification of compulsive and compensatory buyers. The questionnaires were administered to 119 Turkish and 123 Greek students (n = 242) enrolled in several universities in Athens and Istanbul. The data collection was conducted in a controlled and standardized way, namely in group-sessions lasting about 5 minutes, which were conducted and supervised by co-workers of the involved universities. The results have shown that the percentage of compensatory buyers, but not compulsive buyers, within the Greek students sample was significantly smaller than within the Turkish student sample. Further as assumed the moderation of the economic situation could be confirmed: More available money only has a facilitating effect on compulsive buying tendencies under a positive economic environment. Anticipations about the financial situation and the general economic climate are more relevant for compulsive buying tendencies than one's actual available money. Compensatory, but not compulsive buying was significantly smaller under crisis.

Accurate and timely information about land use and land cover (LULC) and its changes in urban areas are crucial for urban land management decision-making, ecosystem monitoring and urban planning. Also, monitoring and representation of urban sprawl and its effects on the LULC patterns and hydrological processes of an urbanized watershed is an essential part of water resource planning and management. This paper presents an image analysis study using multi temporal digital satellite imagery of LULC and changes in the Kucukcekmece Watershed (Metropolitan Istanbul, Turkey) from 1992 to 2006. The Kucukcekmece Basin includes portions of the Kucukcekmece District within the municipality of Istanbul so it faces a dramatic urbanization. An urban monitoring analysis approach was first used to implement a land cover classification. A change detection method controlled with ground truth information was then used to determine changes in land cover. During the study period, the variability and magnitude of hydrological components based on land-use patterns were cumulatively influenced by urban sprawl in the watershed. The proposed approach, which uses a combination of Remote Sensing (RS) and Geographical Information System (GIS) techniques, is an effective tool that enhances land-use monitoring, planning, and management of urbanized watersheds.

Aim of this study was to determine prevalence of cigarette smoking and hookah use among 10th grade students in Istanbul, Turkey, and to compare sociodemographic, psychological and behavioral variables according to frequency of tobacco use. Cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul/Turkey. The questionnaire included sections about demographic data, family characteristics, school life, psychological symptoms and use of substances including tobacco, hookah, alcohol, marijuana, volatiles, heroin, cocaine, non-prescribed legal tranquillizers (benzodiazepines, alprazolam etc.) and illegal tranquillizers (flunitrazepam). The analyses were conducted based on the 4957 subjects. Trial at least once in life is observed as 45.4% for hookah use and as 24.4% for cigarette use. Risk of hookah and cigarette use was significantly higher in male students than in female students. Frequency of tobacco use is related with various sociodemographic, psychological and behavioral variables. Our data also shows that using tobacco and alcohol increases the risk of all the other substances use and these effects are interrelated. The data suggest that there is a link between tobacco use and substance use, psychological, behavioral and social factors. There is also a strong association between tobacco use and suicidal behavior as well as self-mutilative, impulsive, hyperactive, delinquent, aggressive and behavioral problems. The illumination of these relationships may be relevant in prevention and management of tobacco use as well as important problems, such as substance use, impulsivity, hyperactivity, delinquent, aggressive self-mutilative and suicidal behavior among 10th grade students in Istanbul.

The aim of this study was to compare the efficacy of intra-articular injections of three different agents with well known anti-inflammatory properties. Between April 2010 and January 2013 a total of 100 patients who were diagnosed as temporomandibular joint disorder in the Department of Otolaryngology at Bozok University School of Medicine were prospectively studied. Patients with symptoms of jaw pain, limited or painful jaw movement, clicking or grating within the joint, were evaluated with temporomandibular CT to investigate the presence of cartilage or capsule degeneration. In the study group there were 55 female and 45 male patients who were non-responders to conventional anti-inflammatory treatment for TMJ complaints. The patients were randomly divided into four groups consisting of a control group and three different groups who underwent intra-articular injection of one given anti-inflammatory agent for each group. We injected saline solution to intra-articular space in the control group. Of three anti-inflammatory agents including hyaluronic acid (HA, Hyalgan intra-articular injection, Sodium hyaluronate 10 mg/ml, 2 ml injection syringe, Bilim Pharmaceutical Company, Istanbul, Turkey); betamethasone (CS, Diprospan flacon, 7.0 mg betamethasone/1 ml, Schering-Plough Pharmaceutical Company, Istanbul, Turkey) and; tenoxicam (TX, Tilcotil flacon, 20 mg tenoxicam/ml, Roche Pharmaceutical Company, Istanbul, Turkey) were administered intra-articularly under, ultrasonographic guidance. Following the completion of injections the, changes in subjective symptoms were compared with visual analogue scales, (VAS) scores at 1st and 6th weeks' follow-up visits between four groups. The HA group did significantly better pain relief scores compared to the, other groups at 1st and 6th weeks (p < 0.05). TX and CS groups' pain scores were better than control group values (p < 0.05, for both agents). The pain relief effect of TX was noted to decrease significantly between the 1st and 6th week (p < 0.05) (Fig. 1). We did not observe the same pattern in HA, CS and control (saline) groups between 1st and 6th week (p > 0.05). We found that HA produced better pain relief scores when compared to the other anti-inflammatory agents studied. The main disadvantage of HA is its relatively higher cost. Additionally it does not have a reimbursement status by state or private health insurance systems in Turkey. Despite the lower VAS scores, intra-articular TX and CS may be assessed as more economic alternatives to intra-articular HA injections.

Disinfection, antisepsis and sterilization (DAS) practices are of critical importance in hospital practice. This study aims to investigate the daily DAS practices of private hospitals in Istanbul, Turkey. The DAS practices of 155 private hospitals in Istanbul province were investigated using a questionnaire including 26 questions. The questionnaire forms were faxed to all private hospitals located in Istanbul. A p value < 0.05 accepted as significant. The 75 [48%] hospitals out of 155 hospitals responded. The quality of DAS practice was correlated with hospital bed capacity. In these hospitals, glutaraldehyde (27%) was the most common chemical used to disinfect endoscopy instruments. The rate of availability of air gun in endoscopy units in these hospitals was significantly associated with hospital bed capacity (p <0.001). Sticky mats placed at doors of risky areas were not reported to be used in the large bed capacity (LBC) hospitals unlike the small bed capacity (SBC) hospitals where 50% of these hospitals reported to use the sticky door mats (p =0.0144). Private hospitals in Istanbul need in-service training towards sterilization and disinfection issues. It is concluded that private hospitals need policies and educational activities for DAS practices.

According to the WHO, only 5-20% of the total cases of leishmaniasis are symptomatic leishmaniasis; the other cases are identified as asymptomatic leishmaniasis. In recent studies, it has been demonstrated that donor blood plays an important role in the epidemiology of asymptomatic leishmaniasis. However, the number of the studies on this subject is still insufficient. Additionally, donor blood samples obtained from Istanbul, which is the biggest metropolitan area in Turkey, have not been investigated with regard to Leishmania. Moreover, there is no information about the sensitivity of noninvasive serological methods that are used in the detection of leishmaniasis donor blood samples. Accordingly, this study aimed to investigate the presence of antileishmanial antibodies in blood samples obtained from blood bank donors in Istanbul, by using different serologic methods, and to determine the most sensitive detection method. Blood samples were taken from 188 healthy blood bank donors to the Capa Turkish Red Crescent Blood Bank (Istanbul, Turkey), and the presence of antileishmanial antibodies was measured by indirect immunofluorescent antibody test (IFAT), ELISA, immunochromatographic dipstick rapid test, and western blot (WB). Antileishmanial antibodies were determined in 12 out of 188 samples by IFAT (6.4%), and six out of these 12 donors were found to be positive at diagnostic titer 1:128 (3.2%). One hundred and eighty eight samples were investigated by ELISA and one (0.5%) of them gave a positive result. None of 188 samples provided a positive result by immunochromatographic test. WB applied to the 12 seroreactive donors showed that three out of 12 donors were positive. In this study, the presence of antileishmanial antibodies in blood samples of blood bank donors from Istanbul has been demonstrated by using feasible and low-cost serological methods. Additionally, in comparison with other simple and low-cost detection methods, WB was used for confirmation. IFAT has a higher sensitivity and therefore may be preferred as a prescreening method in endemic or nonendemic areas.

A system dynamics approach for healthcare waste management: a case study in Istanbul Metropolitan City, Turkey.

PubMed

Ciplak, Nesli; Barton, John R

2012-06-01

Healthcare waste consists of various types of waste materials generated at hospitals, medical research centres, clinics and laboratories. Although 75-90% of this waste is classified as 'domestic' in nature, 20-25% is deemed to be hazardous, which if not disposed of appropriately, poses a risk to healthcare workers, patients, the environment and even the whole community. As long as healthcare waste is mixed with municipal waste and not segregated prior to disposal, costs will increase substantially. In this study, healthcare waste increases along with the potential to decrease the amounts by implementing effective segregation at healthcare facilities are projected to 2040. Our long-term aim is to develop a system to support selection and planning of the future treatment capacity. Istanbul in Turkey was used as the case study area. In order to identify the factors affecting healthcare waste generation in Istanbul, observations were made and interviews conducted in Istanbul over a 3 month period. A system dynamics approach was adopted to build a healthcare waste management model using a software package, Vensim Ple Plus. Based on reported analysis, the non-hazardous municipal fraction co-disposed with healthcare waste is around 65%. Using the projected waste generation flows, reducing a municipal fraction to 30% has the potential to avoid some 8000 t year(-1) of healthcare waste by 2025 and almost 10 000 t year(-1) by 2035. Furthermore, if segregation practices ensured healthcare waste requiring incineration was also selectively managed, 77% of healthcare waste could be diverted to alternative treatment technologies. As the throughput capacity of the only existing healthcare waste treatment facility in Istanbul, Kemerburgaz Incinerator, has already been exceeded, it is evident that improved management could not only reduce overall flows and costs but also permit alternative and cheaper treatment systems (e.g. autoclaving) to be adopted for the healthcare waste.

Health-care waste management has been a significant problem in most economically developing countries as it is in Turkey. Most of the time, the main reason for the mismanagement of these wastes is the lack of appropriate legislation and effective control; other reasons are: financial strains and a lack of awareness. Being aware of the significance of the subject, in this paper the management of the health-care wastes in Istanbul, as a Metropolitan City of Turkey, was analyzed to create an integrated health-care waste management system in the city. Within the scope of the study, the existing situation and management practicesmore » such as the amount of the health-care wastes generated, segregation procedures, collection, temporary storage and transportation of the wastes within and outside of the institution were examined. Deficiencies, inconsistencies and improper applications were revealed. The existing Turkish Medical Wastes Control Regulation and institutional structure of the health-care waste management body were reviewed. After the evaluation and comparison with the requirements of other national and international organizations, items to be changed/added in the Regulation were identified. At the end of the study, the best management methods for the Istanbul City were determined and started to be applied at the institutions. After this study, the existing Regulation has been changed. The modified Regulation was published in 2005 and implementation has started. It is expected that by the application and implementation of the research outcomes, the management of health-care wastes in Istanbul and then in all over Turkey will be improved. The results obtained can also be used in most economically developing countries where there are similar environmental problems and strict budgets.« less

Abortion services at hospitals in Istanbul.

Despite the existence of a liberal law on abortion in Turkey, there is growing evidence that actually securing an abortion in Istanbul may prove difficult. This study aimed to determine whether or not state hospitals and private hospitals that accept state health insurance in Istanbul are providing abortion services and for what indications. Between October and December 2015, a mystery patient telephone survey of 154 hospitals, 43 public and 111 private, in Istanbul was conducted. 14% of the state hospitals in Istanbul perform abortions without restriction as to reason provided in the current law while 60% provide the service if there is a medical necessity. A quarter of state hospitals in Istanbul do not provide abortion services at all. 48.6% of private hospitals that accept the state health insurance also provide for abortion without restriction while 10% do not provide abortion services under any circumstances. State and private hospitals in Istanbul are not providing abortion services to the full extent allowed under the law. The low numbers of state hospitals offering abortions without restriction indicates a de facto privatization of the service. This same trend is also visible in many private hospitals partnering with the state that do not provide abortion care. While many women may choose a private provider, the lack of provision of abortion care at state hospitals and those private hospitals working with the state leaves women little option but to purchase these services from private providers at some times subtantial costs.

Fluorine determination in airborne samples is important due to its spread into the air from both natural and artificial sources. It can travel by wind over large distances before depositing on the Earth's surface. Its concentration in various matrices are limited and controlled by the regulations for causing health risks associated with environmental exposures. In this work, fluorine was determined in PM2.5 airborne samples by high-resolution continuum source electrothermal atomic absorption spectrometry. For these purpose, the PM2.5 airborne particulates were collected on quartz filters using high-volume samplers (500 L/min) in Istanbul (Turkey) for 96 h during January to June in 2 years. Then, instrumental and experimental parameters were optimized for the analyte in airborne samples. The validity of the method for the analyte was tested using standard reference material, and certified values were found in the limits of 95 % confidence level. The fluorine concentrations and meteorological conditions were compared statistically.

Turkey has continuously experienced problems with abuse of, and addiction to, opium derivatives. In this study, we analyzed the relationship between heroin overdose deaths and the characteristics of seized opium derivatives. Data were gathered from the Council of Forensic Medicine of the Ministry of Justice in Istanbul from 1990 to 2000. There were 636 heroin-related deaths during this period, 595 of which were classified as heroin overdose deaths. Mean crude and weighted heroin purities remained relatively constant and were calculated to be 46% (57-34%) and 51% (39-59%), respectively. The weight of heroin and the number of heroin seizures, but not the heroin purity, were significantly associated with the number of heroin-related deaths. Prevention strategies are needed to reduce the number of deaths caused by overdoses in countries situated on drug trafficking routes. These strategies should focus on drug trafficking, by providing increased levels of, and support for, law enforcement, stopping the supply of precursor chemicals, and combating corruption among border officials.

This study explored the normativity of individual life scripts and their relation to actual life story memories across countries (Turkey and Germany) and subcultures (urban vs. rural, of migrant vs. of indigenous descent). Young adults from provincial Karabük and metropolitan Istanbul (Turkey), second generation Turkish migrants and Germans from Frankfurt a.M. (Germany) provided both their individual versions of the life script and seven most important personal memories. We expected the agreement on the life script, that is, its normativity, and correspondingly its guiding influence on the selection of life story memories to correlate positively with a collectivistic, negatively an individualistic cultural orientation, that is, to be highest in provincial Karabük, less in Istanbul, still less in Turkish migrants in Germany, and finally lowest in native Germans. The study confirmed expectations for the normativity of life scripts, but not for the normativity of most important memories. We conclude that the normativity of life scripts is influenced both by the individualist vs. collectivist orientation.

Objectives: To analyze the relationships between temporalis and masseter muscle hypertrophy and temporomandibular joint (TMJ) disc displacement in patients with severe bruxism using magnetic resonance imaging (MRI). Methods: This retrospective study included 100 patients with severe bruxism, referred to the Department of Oral and Maxillofacial Surgery, University of Marmara and Istanbul Medipol University, Istanbul, Turkey, between January 2015 and December 2016. Patients underwent TMJ MRI with a 1.5-T system in open and closed mouth positions. The masseter and temporalis muscles were measured in the axial plane when the patient’s mouth was closed. Results: At its thinnest, the disc averaged was 1.11±0.24 mm. At their thickest, the masseter averaged was 13.65±2.19 mm and temporalis muscles was 12.98±2.4 mm. Of the discs, 24% were positioned normally, 74% were positioned anteriorly, and 2% were positioned posteriorly. The temporalis muscle was significantly thicker in patients with normally positioned discs than in those with anteriorly positioned discs (p=0.035). Conclusions: The temporalis muscle was significantly thicker in patients with normally positioned discs than in those with anteriorly positioned discs (p=0.035). Additional studies should be conducted to evaluate the relationships between all masticatory and surrounding muscles and disc movements in patients with bruxism. PMID:29332113

Treatment and disposal alternatives for health-care waste in developing countries--a case study in Istanbul, Turkey.

Efficient health-care waste management is crucial for the prevention of the exposure of health-care workers, patients, and the community to infections, toxic wastes and injuries as well as the protection of the environment (Safe Management of Wastes from Health-care Activities. World Health Organization, Geneva). The amount of health-care waste produced in the Istanbul Metropolitan City in Turkey is 30 ton day(-1) in total. The method used for the final disposal of most of the health-care waste of Istanbul is incineration. However, a great portion of the infectious waste is disposed of with the domestic waste into the sanitary landfill because of improper segregation practices applied in the health-care institutions. Therefore the alternatives for the treatment and disposal of health-care waste were evaluated. The technical information related to the available treatment technologies including incineration, microwave irradiation, mobile or stationary sterilization, etc. were also investigated. The capital investment cost, transportation/operational costs for each alternative method and the different locations for installation were compared. When the data collected were evaluated, it was found that separate handling and disposal of health-care waste generated on the European and the Asian sides of the city was the most economic and practicable solution. As a result, it was concluded that the capacity of the Kemerburgaz-Odayeri incineration plant is enough to incinerate the health-care waste generated on the European side of Istanbul, the construction of a new incineration plant or a stationary sterilization unit for the disposal of health-care waste generated on the Asian side was the most effective alternative.

Istanbul has the highest incidence of tuberculosis (TB) in Turkey. It is also the largest city, with considerable differences in quality of life across its urban regions. The aim of this study is to investigate the relationship between (i) the diverse quality of life across specific urban regions, (ii) TB incidence rates, inclusive of demographic and clinical characteristics of TB patients, and (iii) adverse treatment outcomes. This retrospective study included 23,845 new TB patients (recorded in the National TB Registry between 2006 and 2010) in Istanbul. Thirty-nine urban districts of Istanbul were ranked into five groups on the basis of an urban quality of life index. Patient data were matched with these groups, and further categorized according to 'age', 'sex', 'country of birth' and 'antibiotics resistance'. Adverse treatment outcomes and TB incidence rates were extracted from official records. Logistic regression, clustered analyses, 95% CI and p values (STATA) were reported to describe the association between variables. Six per cent of total cases had 'at least one adverse treatment outcome' (default 3.8%, failure 0.5%, death 1.7% in total cases). 'An adverse treatment outcome' was found to be associated with age OR (CI 95%) (1.02 (1.01-1.03)); 'male sex' 1.65 (1.28-2.12); 'other country of birth' 4.82 (3.05-7.62); 100,000 per 'over 60' insidence goups 1.61 (1.32-1.97), the lowest quality of life index 0.65 (0.47-0.83). Patients with high tuberculosis risk factors living in high incidence regions need to be closely monitored. Patients living in lower ranking regions are more likely to have 'poor treatment outcomes'.

The purpose of this study was to establish species distribution of Candida isolates from pediatric patients in Istanbul, Turkey, and to determine risk factors associated with nosocomial Candida infections. This study was conducted between June 2013 and June 2014 by participation of 7 medical centers in Istanbul. Candida spp strains isolated from the clinical specimens of pediatric patients were included. Clinical features were recorded on a standardized data collection sheet. A total of 134 systemic Candida infections were identified in 134 patients. The patients were admitted in pediatric and neonatal intensive care units (41.8% and 9.7%, respectively) and in pediatric wards (48.5%). Candida albicans was the most prevalent species (47%), followed by Candida parapsilosis (13.4%), Candida tropicalis (8.2%), Candida glabrata (4.5%), Candida lusitaniae (3.7%), Candida kefyr (2.2%), Candida guilliermondii (1.5%), Candida dubliniensis (0.7%), and Candida krusei (0.7%). Types of Candida infections were candidemia (50.7%), urinary tract infection (33.6%), surgical site infection (4.5%), central nervous system infection (3.7%), catheter infection (3.7%), and intra-abdominal infection (3.7%). In multivariate analysis, younger age (1-24 months) and detection of non-albicans Candida spp was found to be risk factors associated with candidemia (P = 0.040; odds ratio [OR], 4.1; 95% confidence interval [CI], 1.06-15.86; and P = 0.02; OR, 2.4; 95% CI, 1.10-5.53, respectively). This study provides an update for the epidemiology of nosocomial Candida infections in Istanbul, which is important for the management of patients and implementation of appropriate infection control measures.

Abstract Background and aims: Few studies about compulsive buying consider the economic framing situation. This study is concerned with the impact of different economic environments - the crisis in Greece vs. the boom in Turkey - on compulsive buying tendencies of students, while taking the role of gender and available money into account. Methods: Compulsive buying was measured by a Greek and Turkish translation of the German Compulsive Buying Scale (Raab, Neuner, Reisch & Scherhorn, 2005) in Greece and Turkey, which enabled an identification of compulsive and compensatory buyers. The questionnaires were administered to 119 Turkish and 123 Greek students (n = 242) enrolled in several universities in Athens and Istanbul. The data collection was conducted in a controlled and standardized way, namely in group-sessions lasting about 5 minutes, which were conducted and supervised by co-workers of the involved universities. Results: The results have shown that the percentage of compensatory buyers, but not compulsive buyers, within the Greek students sample was significantly smaller than within the Turkish student sample. Further as assumed the moderation of the economic situation could be confirmed: More available money only has a facilitating effect on compulsive buying tendencies under a positive economic environment. Conclusions: Anticipations about the financial situation and the general economic climate are more relevant for compulsive buying tendencies than one’s actual available money. Compensatory, but not compulsive buying was significantly smaller under crisis. PMID:25317341

To determine what should be done as a preventive medicine physician by analysing the effect of polypharmacy and herbal treatment. This survey-based, cross-sectional study was carried out at Istanbul Okmeydani Training and Research Hospital, Istanbul, Turkey, from February to May 2015, and comprised patients using two or more medicines at full strength for at least 240 days. The patients were classified into two groups. Group A comprised those who were using less than 4 medications (at least 2), while group B comprised patients using more than 4 medications. The short version of World Health Organisation's quality-of-life questionnaire was applied. SPSS 22 was used for data analysis. Of the 350 participants, 106(30.3%) were receiving herbal treatment while 244(69.7%) had no such treatment. Group B patients had meaningfully lower scores for body, spiritual, social and external environment (p=0.001). Moreover, the patients having no herbal or supportive treatment scored significantly higher in the physical, spiritual, social relations and external environment (p=0.001).

To evaluate the plasma and salivary total antioxidant capacity (TAOC) in patients with generalized chronic periodontitis (CP), generalized aggressive periodontitis (AgP), and periodontally healthy controls. This cross-sectional study includes of 88 individuals seeking dental treatment at the Faculty of Dentistry, Istanbul University, Istanbul, Turkey between January 2011 and March 2012. Fifteen AgP patients were compared with 21 healthy controls (C1), while 36 CP patients were compared with 16 healthy controls (C2). Clinical periodontal measurements were recorded, and plasma and saliva samples were collected. The TAOC of the plasma and saliva samples were determined using a commercially available colorimetric kit. The plasma TAOC of both AgP and CP patients was significantly lower for C1 and C2. The salivary TAOC of CP patients was significantly lower for C2, but there was no significant difference between AgP patients and C1. Our results demonstrate that severe periodontitis may be associated with a lower plasma antioxidant capacity. The reduced antioxidant capacity in patients with severe periodontitis, especially with aggressive forms may be an important contributing factor to severe tissue destruction.

A variation on forced migration: Wilhelm Peters (Prussia via Britain to Turkey) and Muzafer Sherif (Turkey to the United States).

In 1933 the Turkish Republic formally offered university positions to 30 German-speaking academics who were dismissed with the coming to power of the National Socialist Government. That initial number went up to 56 with the inclusion of the technical assistants. By 1948 the estimated total had increased to 199. Given renewable five-year contracts with salaries substantially higher than their Turkish counterparts, the foreign émigrés were to implement the westernization program of higher education. The ten year-old secular Turkish Republic's extensive social reforms had encompassed the adoption of the Latin alphabet, and equal rights for women, removing gender bias in hiring. Such a high concentration of émigré academics in one institution, "the highest anywhere in the world," provides a unique opportunity to study a subject which has been neglected. In this article two cases in psychology will be examined: Wilhelm Peters (1880-1963), who came, via Britain, to Istanbul in 1936 from the University of Jena in Germany, and Muzafer Sherif (1906-1988) who went to the United States from Ankara University in 1945. The purpose of the comparative analysis is to identify the features that are specific to the German experience, and those that are shared and underlie translocation in science within the multifaceted complexity of the process of forced migration.

Ulman, Yesim Isil

2005-04-01

The aim of this study was to research the pioneering steps for the employment of chloroform in Turkey in comparison with the developments in the West i.e. in the United States and in Europe. The development of anaesthesiology in the West started in the first half of the 19th century. As an anaesthetic substance, ether was first employed in a medical operation by R. Liston in December 1846. But taking into consideration of its bronchially irritant effect, British gynaecologist Dr. J.Y. Simpson preferred to utilize chloroform in obstetrical operations in 1847. The paper aims at shedding light on the earlier steps for modern anaesthesiology in Turkey in that sense. The survey used evaluation of archival documents, first hand-original sources such as the annual medical reports of the Medical School, books, official journals, and newspapers of the time, and also secondary sources concerned with the subject. In view of the findings of the survey, chloroform, as an anaesthetic material, began to be administered surgically in Turkey much earlier than it was already known. It was experienced and used in operations at the surgical clinic of the Imperial School of Medicine at the Capital city, Istanbul in 1848. The Crimean War (1853-1855) induced to the prevalent surgical use of chloroform in Istanbul on the soldiers back from the front. In other words, it was evidenced that surgeons started to make use of this anaesthetic substance in the Ottoman Empire, shortly after it was put into medical practice in Europe. This study deals with that phenomenal progress of chloroform anaesthesia in the medical history in Turkey during the second half of the 19th century.

Nowadays traffic accidents, which have high mortality and morbidity, are an important public health problem. The association between the use of alcohol and/or drugs by drivers and the increased risk of traffic accidents with a high risk of death and injury has been well described in the literature. This study aimed to review the incidence of cases of driving under the influence of drugs (DUID) among all cases of driving under the influence (DUI) of alcohol and/or other drugs involved in traffic accidents and to evaluate the type of the psychoactive drugs (with or without alcohol) detected in blood samples in Istanbul and its surrounding area. This study is the first investigation on the subject of DUID cases in Turkey. The reports of the Istanbul Toxicology Department of the Council of Forensic Medicine (Turkey) on suspected DUID cases involved in traffic accidents between 1 July 2010 and 30 June 2011 were retrospectively reviewed for alcohol and/or drug use. Alcohol analysis was requested in 4274 suspected DUI cases, whereas drug along with alcohol analysis was requested in only 91. The rate of suspected DUID cases (n = 91) among the suspected DUI cases (n = 4274) was only 2.1% and in this study, we evaluated only the DUID cases in detail. Alcohol was present in 44% of suspected DUID cases. Psychoactive drugs were present in 15.4% of cases. The incidence among 46 confirmed DUID cases was found to be 17.4% for cannabis, 8.7% for benzodiazepines, 4.3% for barbiturates, 4.3% for antidepressants, 2.2% for cocaine and 2.2% for amphetamines. Although there is a zero-tolerance approach for DUID in the Turkish regulations, it is not well recognised and not inspected by police and legal authorities who are responsible for taking measures in traffic accidents and for routine traffic controls in Turkey. It is concluded that psychoactive drugs should be checked as well as alcohol in all traffic accident cases and roadside controls.

Dalfes, H. N.; Ülgen, H.; Zeydanli, U.; Durak, A. T.

2012-04-01

All climate projections indicate that drastic changes are to occur in the Mediterranean Basin and Southwestern Asia. Detailed studies also foresee strong patterns of change in seasonality for most climate fields all across the country, threatening Turkey's rich biodiversity and diverse ecosystems already in trouble due to massive land use changes and careless resource extraction projects. It is therefore obvious that climate impact studies can benefit from detailed and continuous monitoring of relationships between climate and natural systems. Recently started efforts to build a phenology network for Turkey will hopefully constitute a component of a more comprehensive ecological observation infrastructure. The Phenology Network of Turkey Project saw its debut as a joint initiative of an academic institution (Istanbul Technical University) and a research NGO (Nature Conservation Center). It has been decided from the very beginning to rely a much as possible on Internet technologies (provided by the National High Performance Computing Center of Turkey). The effort is also inspired by and collaborates with already established networks in general and USA National Phenology Network in particular. Many protocols, instructional materials and Nature's Notebook application has been barrowed from the USA NPN. The project has been designed from the start as a two-faceted effort: an infrastructure to accumulate/provide useful data to climate/ecosystem research communities and a 'citizen science' project to raise nature and climate change awareness among all components of the society in Turkey in general and secondary education teachers and students in particular. It has been opted to start by gathering plant phenological data. A set with 20 plant species has been designed to serve as a countrywide 'calibration set'. It is also anticipated to salvage and extend as much of possible historical animal (especially bird and butterfly) observations.

Turkey is one of the countries facing a serious organ shortage problem, with thousands of patients with end-stage organ failure. The Social Security Institution started to increase the reimbursement for transplantation operations in 2007 to solve this problem, and this policy has continued since then. Although the number of transplantation centers and operations in Turkey increased in this term, according to organ donation and transplantation statistics from the Ministry of Health, the rate of organ retrieval from deceased organ donors has decreased. This study was performed with the purpose of retrospectively analyzing (between the years 2005 and 2015) the number of brain deaths and donors after brain death in hospitals that are affiliated with the Istanbul Regional Coordination Office and have transplantation units. Data were collected via the website of the Ministry of Health. Hospitals were categorized as those directly affiliated with the Ministry of Health, university hospitals, and private hospitals. This study found that the number of transplantation centers has increased >3 times since 2005, and the number of private transplantation centers has increased 9 times for the same period. We also found that the number of brain deaths, donors after brain death in hospitals, and number of brain deaths and donors after brain death per hospital had varied throughout the study years. Although the number of transplantation centers has increased since 2005, the number of brain deaths and donors after brain death has not increased to the same extent for this period in these hospitals that have transplantation units.

This study assessed trends and patterns in antimicrobial resistant intensive care unit (ICU)-acquired infections caused by Gram-negative bacteria (GNB) in Istanbul, Turkey. Bacterial culture and antibiotic susceptibility data were collected for all GNB causing nosocomial infections in five adult ICUs of a large university hospital during 2012-2015. Multi-resistance patterns were categorised as multidrug (MDR), extensively-drug (XDR) and pandrug (PDR)-resistance. Patterns and trends were assessed using seasonal decomposition and regression analyses. Of 991 pathogenic GNB recorded, most frequent were Acinetobacter baumannii (35%), Klebsiella species (27%), Pseudomonas aeruginosa (18%), Escherichia coli (7%) and Enterobacter species (4%). The overall infection rate decreased by 41% from 18.4 to 10.9 cases per 1000 patient-days in 2012 compared to 2015 (p <0.001), mostly representing decreases in bloodstream infections and pneumonias by A. baumannii and P. aeruginosa. XDR proportion in A.baumannii increased from 52% in 2012 to 72% in 2015, but only one isolate was colistin-resistant. Multi-resistance patterns remained stable in Klebsiella, with overall XDR and possible PDR proportions of 14% and 2%, respectively. A back-to-susceptibility trend was noted for P. aeruginosa in which the non-MDR proportion increased from 53% in 2012 to 71% in 2015. 88% of E.coli and 40% of Enterobacter isolates were MDR, but none was XDR. Antimicrobial resistance patterns in pathogenic GNB continuously change over time and may not reflect single-agent resistance trends. The proportionate amount of antimicrobial-resistant GNB may persist despite overall decreasing infection rates. Timely regional surveillance data are thus imperative for optimal infection control.

Zulfikar, Can; Pinar, Ali

2016-04-01

There are several EEW networks and algorithms under operation in Turkey. The first EEW system was deployed in Istanbul in 2002 after the 1999 Mw7.4 Kocaeli and Mw7.1 Duzce earthquake events. The system consisted of 10 strong motion stations located as close as possible to the main Marmara Fault line. The system was upgraded by 5 OBS (Ocean Bottom Seismometer) in 2012 located in Marmara Sea. The system works in threshold based algorithm. The alert is given according to exceedance of certain threshold levels of amplitude of ground motion acceleration in certain time interval at least in 3 stations. Currently, there are two end-users of EEW system in Istanbul. The critical facilities of Istanbul Gas Distribution Company (IGDAS) and Marmaray Tube tunnel receives the EEW information in order to activate their automatic shut-off mechanisms. The IGDAS has their own strong motion network located at their district regulators. After receiving the EEW signal if the threshold values of ground motion parameters are exceeded the gas-flow is cut automatically at the district regulators. The IGDAS has 750 district regulators distributed in Istanbul. At the moment, the 110 of them are instrumented with strong motion accelerometers. As a 2nd stage of the on-going project, the IGDAS company proposes to install strong motion accelerometers to all remaining district regulators. The Marmaray railway tube tunnel is the world's deepest immersed tube tunnel with 60m undersea depth. The tunnel has 1.4km length with 13 segments. The tunnel is monitored with 2 strong motion accelerometers in each segment, 26 in total. Once the EEW signal is received, the monitoring system is activated and the recording ground motion parameters are calculated in real-time. Depending on the exceedance of threshold levels, further actions are taken such as reducing the train speed, stopping the train before entering the tunnel etc. In Istanbul, there are also on-site EEW system applied in several high-rise buildings. As similar to threshold based algorithm, once the threshold level is exceeded in several strong motion accelerometers installed in the high-rise building, the automated shut-off mechanism is activated in order to prevent secondary damage effects of the earthquakes. In addition to the threshold based EEW system, the regional EEW algorithms Virtual Seismologist (VS) as implemented in SeisComP3 VS(SC3) and PRESTo have been also implemented in Marmara region of Turkey. These applications use the regional seismic networks. The purpose of the regional EEW systems is to determine the magnitude and location of the event from the P-wave information of the closest 3-4 stations and forward this information to interested sites. The regional EEW systems are also important for Istanbul in order to detect far distance earthquake events and provide alert especially for the high-rise buildings for their long duration shaking.

Allergic rhinitis (AR) is a global health problem affecting many people from childhood to adulthood. The aim of this study was to evaluate the prevalence of AR and related symptoms, and to assess the risk factors, dietary habits and the Mediterranean diet affecting AR. In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AR symptoms among the children was evaluated using the ISAAC protocol. In our study, total of 10,984 questionnaires were distributed to 13-14yr-old schoolchildren to 61 schools in 32 district of Istanbul and 9991 questionnaires were suitable for analysis with an overall response of 91.7%. The rates of lifetime rhinitis, rhinitis in last 12 months and lifetime doctor diagnosed AR prevalence were 53.5%, 38.3% and 4.5%, respectively. The variation among districts in the prevalence of doctor diagnosed AR was very high. The highest prevalence was about 10 times higher than in the district with the lowest prevalence (range: 1.4-14.5) of Istanbul. A family history of atopy, mother with a university degree, presence of cat at home during last 12 months and adenoidectomy were significant for increased doctor diagnosed AR risk. Additionally, although fish and other sea foods, fermented drinks made from millets and various seeds, animal fats and butter were independent risk factors for doctor diagnosed AR, fish oil and hamburger were protective foods for doctor diagnosed AR. The MD was not associated with the prevalence of doctor diagnosed AR. This study shows that that there are wide variations for the prevalence of AR related symptoms in 13-14yr-old schoolchildren among districts of Istanbul in Turkey. Socio-economical, environmental factors, some dietary habits, but not Mediterranean diet may affect the prevalence of AR. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Restoration of the iconic Golden Horn Estuary in Istanbul, Turkey was a substantial political, logistical, ecological, and social challenge. Forty years of uncontrolled industrial and urban growth resulted in thick layers of anoxic sediment, toxic bacteria, strong hydrogen sulfide odor, and ecologically unlivable conditions. The major components of restoration, spanning two decades, have included (1) demolition and relocation of industries and homes along the shore, (2) creation of wastewater infrastructure, (3) removal of anoxic sludge from the estuary, (4) removal of a floating bridge that impeded circulation, and (5) creation of cultural and social facilities. Although Turkey is not known as an environmental leader in pollution control, the sum of these efforts was largely successful in revitalizing the area through dramatic water quality improvement. Consequently, the estuary is once again inhabitable for aquatic life as well as amenable to local resource users and foreign visitors, and Istanbul has regained a lost sense of cultural identity. This paper focuses on literature review and personal interviews to discuss the causes of degradation, solutions employed to rehabilitate the estuary, and subsequent physicochemical, ecological, and social changes.

The boron content was determined in 42 different foods consumed in Istanbul, Turkey. Eleven species of fruit, ten species of vegetable, eight species of food of animal origin, four species of grain, two species of nuts, two species of legume, and five other kinds of foods were included to this study. They were analyzed by two methods: Inductively coupled plasma mass spectrometry (ICP-MS) technique and carminic acid assay, and the results of two methods were also compared. Boron concentration in foods ranged between 0.06-37.2 mg/kg. Nuts had the highest boron content while foods of animal origin had the lowest. A strong correlation was found between the results of the carminic acid assay and the ICP-MS technique (p = 0.0001, Pearson correlation coefficient: r = 0.956). Bland Altman analysis also supported this correlation. ICP-MS is one of the most common, reliable, and powerful method for boron determination. The results of our study show that spectrophotometric carminic acid assay can provide similar results to ICP-MS, and the boron content in food materials can be also determined by spectrophotometric method.

To assess the awareness of childhood autism among physicians undergoing residency training in various disciplines. This cross-sectional study was conducted at a research and training hospital in Istanbul, Turkey, in February 2013 and comprised physicians undergoing residency training in various disciplines. Data was collected through a self-administered questionnaire. Questions about "awareness on autism" were prepared in the light of "Knowledge about Childhood Autism among Health Workers questionnaire. Of the 128 physicians, 122(95.3%) were aware that the most known characteristic of childhood autism was "failure to build-up friendship". All of the 29(22.66%) physicians at the neuropsychiatric disciplines were aware that "autism can be a genetic disorder", whereas, in other disciplines 69(69.7) physicians had that awareness. Besides, 15(51.7%) of the residents of the neuropsychiatric disciplines thought that "autism can be associated with childhood epilepsy", while 32(32.3%) physicians of other disciplines gave a similar answer (p=0.057). The awareness on childhood autism of residents belonging to the non- neuropsychiatric disciplines was moderate.

Maritime transportation plays an important role in the world. Commercial transport and navy are international maritime activities in different countries. Thanks to the role of straits and channels, these activities can be easier and faster, Turkey has a crucial importance on it because of importance of geographical location. The Turkish Straits are a series of internationally significant waterways connecting Mediterranean Sea and Black Sea. They consist of the Canakkale Strait, the Sea of Marmara, and the Istanbul Strait, all part of the sovereign sea territory of Turkey and subject to the regime of internal waters. They are conventionally considered by the boundary between the continents of Europe and Asia. Because of this geographical importance, all kinds of huge sized vessel activities and high volume cargo transportation always keep going in this waterway. On the other hand, the more maritime activities grow the more accident risks increase. So, can be examined the accident risks on Istanbul and Canakkale Straits and can be assessed risk analysis for them. In the context of the study, one can see general information of the Turkish Straits and the regulatory regime. In addition, tables are applied for vessel movement in the Turkish Straits by years in detail in order to sense variation of the vessel. Risk analyses may also be described in sections with many variables. This paper outlines ship accidents and the risk analysis of ship accidents is applied and resulted for the Turkish Straits. The last chapter concerns the Vessel Traffic Service (VTS) System in the Turkish Straits.

Astro-geodetic deflections of the vertical components provide accurate and valuable information of Earth's gravity filed. Conventional methods require considerable effort and time whereas new methods, namely digital zenith camera systems (DZCS), have been designed to eliminate drawbacks of the conventional methods, such as observer dependent errors, long observation times, and to improve the observation accuracy. The observation principle is based on capturing star images near zenithal direction to determine astronomical coordinates of the station point with the integration of CCD, telescope, tiltmeters, and GNSS devices. In Turkey a new DZCS have been designed and tested on control network located in Istanbul, of which the geoid height differences were known with the accuracy of ±3.5 cm. Astro-geodetic Camera System (ACSYS) was used to determine the deflections of the vertical components with an accuracy of ±0.1 - 0.3 arc seconds, and results were compared with geoid height differences using astronomical levelling procedure. The results have also been compared with the ones calculated from global geopotential models. In this study the recent results of the first digital zenith camera system of Turkey are presented and the future studies are introduced such as the current developments of the system including hardware and software upgrades as well as the new observation strategy of the ACSYS. We also discuss the contribution and integration of the astro-geodetic deflections of the vertical components to the geoid determination studies in the light of information of current ongoing projects being operated in Turkey.

The goal of this study was to compare perceptions of menopausal symptoms among migrant women from Turkey in Berlin (TB), German women in Berlin (GB), and women in Istanbul (TI). The aim was to analyze findings in light of the possible influences of sociodemographic, psychosocial, and migration-related aspects. The study participants (aged 45-60 y) were recruited via random and snowball sampling and surveyed with a structured questionnaire in the German and Turkish languages, which contained questions about their experiences with the menopausal phase and related symptoms (Menopause Rating Scale II), menopausal hormone therapy, and sociodemographic, psychosocial, and migration-related aspects. Statistical analysis was performed with univariate Fisher's exact test, factor analysis, and multivariate logistic regression. A total of 963 women participated in the study. Premenopausal/perimenopausal migrant women from Turkey in Berlin most frequently reported severe vegetative complaints (TB, 49.9%; GB, 34.9%; TI, 34.9%) and genital complaints (TB, 39.2%; GB, 32.3%; TI, 29.4%), as defined by factor analysis. In postmenopausal migrant women from Turkey in Berlin, the most frequently reported symptoms belonged to the domain of psychological complaints (TB, 52.7% vs GB, 24.0%; TI, 55.7%). Gradual multivariate logistic regression revealed sociodemographic and health-related risk factors as predictive factors for the defined menopausal complaints. Migration-related factors might be decisive for women's experience of menopause. Improvement of population-tailored access to factual information about menopause and treatment options is an area of great potential to support women in this phase.

The human nasopharynx is the main reservoir of Neisseria meningitidis, and asymptomatic carriage is common. N. meningitidis one of the common causes of bacterial meningitis in Turkey, especially after the implementation of the national immunization program that includes conjugated pneumococcal and Haemophilus influenzae type b vaccines. The purpose of this study was to evaluate the prevalence of meningococcal carriage and determine the leading serogroup, which may help authorities to adapt appropriate meningococal vaccine into the national immunization programme. The prevalence of oropharyngeal carriage of N. meningitidis in 1,000 healthy subjects, 0-79 years of age, was investigated. Oropharyngeal swabs were collected during an 18-month period. Samples obtained were inoculated onto Thayer-Martin agar. The API-NH test and VITEK-MS system were used for identification of colonies. Multiplex real-time polymerase chain reaction assay was used to determine serogroups with serogroup-specific genes. N. meningitidis was isolated from 6 of 1,000 subjects (0.6%). Meningoccocal carriers were between 21 and 40 years of age. All isolates were serogrouped as B, except one that did not survive on subculture. N. lactamica was isolated from 13 of 1,000 subjects (1.3%). Carriage rate of meningococci in our study was relatively low. However, we detected that serogroup B was the leading strain in meningococcal carriage in Istanbul; choosing an appropriate meningococcal vaccine containing serogroup B should therefore be considered. High absolute humidity throughout the year in Istanbul may explain the low prevalence of carriage in our study. This should be verified with a multicenter national survey.

To evaluate the caries experience, oral hygiene status and oral health knowledge of a group of visually impaired students. The study was conducted at one of the largest visually impaired children's schools among students aged between 7 and 16 years (n = 178) in Istanbul, Turkey. A 16-item questionnaire was asked in addition to a clinical tooth examination. The 16-item verbal questionnaire was developed to record the students' general health, impairment, the socioeconomic profile and education level of their parents, oral health knowledge, sources of information about oral health and oral hygiene habits. Oral hygiene was assessed according to Greene and Vermillion's Simplified Oral Hygiene Index (OHI-S). To measure the oral hygiene status, OHI-S index scores were recorded. Additionally, DMFT and dft indices were documented. Only 26.40% of children were caries free, and only 2.2% of students had good oral hygiene. A total of 3.3% of these students were mildly retarded and 2.8% of them had a developmental disability. Visually impaired children exhibited a fair-to-poor level of oral hygiene. Maintenance of oral hygiene remains the greatest challenge in the care of visually impaired children.

Investigation of norovirus (NoV) contamination of food items is important because many outbreaks occur after consumption of contaminated shellfish, vegetables, fruits, and water. The frequency of NoV contamination in food items has not previously been investigated in Turkey. The aim of this study was to investigate the frequency of human NoV genogroups (G) I and II in ready-to-eat tomatoes, parsley, green onion, lettuce, mixed salads, and cracked wheat balls. RNA was extracted with the RNeasy Mini Kit, and a real-time reverse transcription (RT) PCR assay was performed using primers specific for NoV GI and GII. Among the 525 samples analyzed, NoV GII was detected in 1 green onion sample and 1 tomato sample by both SYBR Green and TaqMan real-time RT-PCR assays; no GI virus was detected. The Enterobactericaeae and Escherichia coli levels in the NoV-positive green onion were 6.56 and 1.28 log CFU/g, and those in the tomato were 5.55 and 1.30 log CFU/g, respectively. No significant difference in the bacterial levels was found between the NoV-positive and NoV-negative samples. This study is the first in which NoV GII was found in ready-to-eat food collected from Istanbul, Turkey; thus, these foods may be considered a risk to human health. Epidemiological studies and measures to prevent NoV infection should be considered.

Istanbul (near North Anatolian Fault Zone:NAFZ, Turkey) is located in northern part of Sea of Marmara, an area that has been influenced by possible Marmara Earthquakes. The general geology of Istanbul divided into two stratigraphic unit such as sedimentary (from Oligocene to Quaternary Deposits) and bedrock (Paleozoic and Eocene). The bedrock units consists of sand stone, clay stone to Paleozoic age and limestone to Eocene age and sedimentary unit consist of sand, clay, mil and gravel from Oligocene to Quaternary age. Earthquake disaster mitigation studies divided into two important phases, too. Firstly, earthquake, soil and engineering structure problems identify for investigation area, later on strategic emergency plan can prepare for these problems. Soil amplification play important role the disaster mitigation and the site effect analysis and basin structure is also a key parameter for determining of site effect. Some geophysical, geological and geotechnical measurements are requeired to defined this relationship. Istanbul Megacity has been waiting possible Marmara Earthquake and their related results. In order to defined to possible damage potential related to site effect, gravity measurements carried out for determining to geological structure, basin geometry and faults in Istanbul. Gravity data were collected at 640 sites by using a Scientrex CG-5 Autogravity meter Standard corrections applied to the gravity data include those for instrumental drift, Earth tides and latitude, and the free-air and Bouguer corrections. The corrected gravity data were imported into a Geosoft database to create a grid and map of the Bouguer gravity anomaly (grid cell size of 200 m). As a previously results, we determined some lineminants, faults and basins beneath Istanbul City. Especially, orientation of faults were NW-SE direction and some basin structures determined on between Buyukcekmece and Kucukcekmece Lake.

MARsite is thus expected to move a "step forward" the most advanced monitoring technologies, and offering promising open databases to the worldwide scientific community in the frame of other European environmental large-scale infrastructures, such as EPOS (http://www.epos-eu.org/ ). Among the 11 work packages (WP), the main aim of the WP6 is to study seismically-induced landslide hazard, by using and improving observing and monitoring systems in geological, hydrogeotechnical and seismic onshore and offshore areas. One of the WP6 specific study area is the Avcilar Peninsula, situated between Kucukcekmece and Buyukcekmece Lakes in the north-west of the region of Marmara. There, more than 400 landslides are located. According to geological and geotechnical investigations and studies, soil movements of this area are related to underground water and pore pressure changes, seismic forces arising after earthquakes and decreasing sliding strength in fissured and heavily consolidated clays. The WP6 includes various tasks and one of these works on a methodology to develop a dynamic system to create combined earthquake and rainfall induced landslides hazard maps at near real time and automatically. This innovative system could be used to improve the prevention strategy as well as in disaster management and relief operations. Base on literature review a dynamic GIS platform is used to combine theoretical models, variable on-site data (rainfall, earthquake, etc), products and results obtained by other WP6 partners' contributions. This platform is in progress, a 1D deterministic method for calculating co-seismic displacements was for the moment implemented in the GIS based on Newmark's method for mapping shallow slides. Rigid sliding block analysis is commonly adopted to predict the potential for earthquake-induced landslides. These predictions give the expected level of displacement as a function of the characteristics of the natural slopes and the characteristics of earthquake shaking. In our case the first characteristics are the results of a precise DEM data and an existent landslide inventory. The geotechnical parameters used come from the literature and will be improved thanks to a borehole geological and geotechnical campaign in progress. The static hydrogeological model in our GIS will be replaced by transient models for hill slope hydrology and time series of intense and/or prolonged precipitation (provided by Tubitak) which will be shortly accessible. Our next aim is to introduce, when ready, site effects information issued from the next IU geophysical campaign, results from numerical simulations and automatic near real time shake maps (developed by KOERI). Moreover, in the spring 2014, an observation & Early Warning System (EWS) prototype system will be set up on an active but slow landslide (pilot site) and composed of GPS devices, seismic probes, piezometers, meteorological station and inclinometers. This will improve our scientific understanding of Avcilar landslides and enable to also improve and better calibrate our GIS platform.

This June 16, 2000 image of Istanbul, Turkey show a full 60 by 60 km ASTER scene in the visible and infrared channels. Vegetation appears red, and urban areas blue-green. Bustling Istanbul, with its magnificent historical heritage, has spanned the divide between Europe and Asia for more than 2,500 years. Originally called Byzantium, the city was founded in the 7th century BC on the Golden Horn, an arm of the narrow Bosporus (also spelled Bosphorus) Strait, which connects the Sea of Marmara to the south, with the Black Sea to the north. Constantine I made it his capital of the Eastern Roman Empire in AD 330. As Constantinople, the strategically located city arose as the preeminent cultural, religious, and political center of the Western world. It reached the height of its wealth and glory in the early 5th century. After centuries of decline, the city entered another period of tremendous growth and prosperity when, as Istanbul, it became the capital of the Turkish Ottoman Empire in 1457. Although Turkey moved its capital to Ankara in 1923, Istanbul remains the nation's largest city with a population of over 8 million, its commercial center, and a major port. Two bridges spanning the Bosporus, and ships in the busy channel can be seen on the enlargement. On the image, the water areas have been replaced with a thermal image: colder waters are displayed in dark blue, warmer areas in light blue. Note the dark lines showing boat wakes, and the cold water entering the Sea of Marmara from deeper waters of the Bosporus.

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.

The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands Evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface heat balance.

[Recent demographic trends in Turkey].

Behar, C

1993-01-01

Coverage of Turkey's vital registration system remains incomplete, and it cannot yet be used to measure annual population changes. Data and demographic indices based on the 1990 census and the 1989 National Demographic Survey are the most recent available. Turkey's population in 1990 was 56 million. The proportion urban increased to 59% from 49.2% in 1980. Nearly 35% of the population was under 15 years old, and the median age was 21.6 for males and 22.3 for females. The average age at first marriage in 1989 was 24.8 for men and 21.8 for women. Mortality has been in continuous decline. The crude death rate dropped from 16.4/1000 in 1960-65 to slightly under 8 in 1989. Life expectancy at birth was 63.3 for men and 66 for women. The infant mortality rate declined from 166 in 1965-70 to 85 in 1989. Rural or urban residence and maternal educational level were the most significant determinants of infant mortality differentials. Turkey's total fertility rate declined from 6.2 in 1960 to 4.3 in 1978 and 3.4 in 1988-89. The crude birth rate declined from around 40/1000 in 1968 to under 28/1000 in 1989. Fertility began to decline in the last third of the nineteenth century in Istanbul and other large cities of the Ottoman Empire. Istanbul's total fertility rate was a relatively low 3.9 even before World War I. Turkey adopted a policy to slow demographic growth in the mid 1960s, and family planning activities were supported by nongovernmental organizations. The direct impact of these policies on demographic behavior appears to have been somewhat limited, and the use of traditional methods of birth limitation remains widespread. Abortion was legalized in 1983 and is available at public hospitals. The proportion of married women aged 15-49 who use contraception increased from 38% in 1973 to 63% in 1988. Regional differentials in demographic indices are significant in Turkey, with the Anatolian East and Southeast lagging behind other regions in fertility and mortality decline, contraceptive usage, and other indicators. Turkey thus appears to be divided into a region in which the demographic transition is well advanced and one where it is proceeding more slowly.

The occurred death of a convict in prison, police custody cell or in a hospital always attracts public attention and can be considered as a complex phenomenon. The aim of this study is to evaluate the data obtained from autopsies performed to the custody and prison deaths in Istanbul and to discuss the possible solutions by comparing with the literature. It is also aimed to discuss the postponement of the sentence and presidential amnesty facts in Turkey. Deaths of inmates, which occurred in hospitals, prisons, prison medical rooms, police vans and police custody cells between 2010 and 2012 in Istanbul, Turkey were included in the study. Totally 125 cases were found and 98.4% of them were male. Natural deaths accounted for a great majority of deaths (83.2%). The most common natural cause was cardiovascular diseases. Unnatural deaths accounted for 15.2% of the deaths. Death reason cannot be determined for 1.6% of the cases. More than half of the cases (56%) were died at the hospital, 34.4% were died at the prison, 4% of them at the police van, 3.2% were died under police custody and 2.4% were died at the prison medical room. Moreover, twelve of these cases had applied to Third Specialization Board previously for postponement of the sentence or Presidential amnesty. Totally five of these cases found suitable for postponement of the sentence. Prison conditions should be improved, prisoners with chronic diseases should be examined periodically and if appropriate their sentences should be postponed until they heal.

2016-12-01

Marinas play a key role in sea transportation and tourism. The problem of an insufficient marina capacity has revealed in terms of sea traffic due to the demographic structure and increasing tourism potential of Istanbul which is the biggest metropolitan city of Turkey and has around 600-km-long coastline. Therefore, the study area is mainly focused on the Marmara Sea shoreline of Istanbul. Rather than traditional methods, a rapid and cost-effective solution which considers natural and urban environment conditions is essential to satisfy the need for a marina site selection. Thanks to the latest improvements in geographic information systems, it is convenient to perform location selection analysis of marinas taking advantages of geology, land use, demography and accessibility data sets. The goal of this study is to define the areas that are appropriate for building marinas, with the use of topographic and demographic data in a present shoreline applying analytical hierarchy process multicriteria decision-making method. In this study, erosion, landslide, tsunami, land use, geologically hazardous areas, transfer lines, sea traffic data, neighbourhood scale population, age patterns and house income data have been used. Analytical hierarchy process method is used to give a weight to each data set, and a grading system has been developed for the area selection of marinas. The result maps of the analysis that show study area as classified into four categories from good to not suitable are presented. It is possible to create a decision support system for upper scale plans that enable authorities to perform analysis accurately, cost and time effectively using the proposed methodology that integrates multiple data sets with different scales and types.

Conflicting societal conceptions of earthquake safety provide challenges but also opportunities for the communication of seismic hazards. This paradox is exemplified in the controversial social reactions to the ongoing 'urban renewal projects' in Istanbul. Seismologists estimate that there is a high probability that a major earthquake will strike Istanbul in the next decade or so. Detailed earthquake risk analysis, and direct experience of the losses suffered during the major earthquakes that struck Turkey in 1999 and 2011, have engendered a broad societal recognition of the need for extensive earthquake preparedness and response planning. However, there has been dissent concerning the democratic legitimation of some of Istanbul's mitigation measures, most notably the implementation of the 'Law for the Regeneration of Areas Under Disaster Risk' (Law 6306, known as the 'disaster law') in May 2012. The strong interconnections between geological 'matters of fact' and societal 'matters of concern' raise fundamental questions for geocommunication on how to deal with this societal complexity, particularly in terms of maintaining trust in the geoscientist. There is a growing recognition among geoscientists that achieving disaster resilience in Istanbul is not solely the domain of 'earthquake experts' but rather requires a shared societal responsibility. However, the question arises as to how geocommunication can be designed to respond to this increased demand for interdisciplinarity and civil participation. This research will confront this question, exploring ways to combine qualitative and quantitative analyses, values and preferred norms with facts and observations, and be organised around an interactive web-based documentary platform that integrates multiple knowledge bases and seeks to help connect different communication cultures.

Endocrine-disrupting compounds (EDCs) are exogenous substances that cause adverse health effects in an intact organism, or its progeny, subsequent to the changes in endocrine function. Recent studies have shown that wastewater treatment plant effluents play an important role in the release of EDCs into aquatic environments. Therefore, in this study, influent and effluent samples from three different wastewater treatment plants (WWTPs) in Istanbul were analysed for the presence of the principal EDCs. These chemicals include steroids and synthetic organic chemicals. Thus, the occurrence and fate of EDCs of great health concern were monitored at three WWTPs in Istanbul. Furthermore, these WWTPs are employing different treatment processes. Therefore, the EDC removal performances of different treatment regimes were also evaluated. Phytosterol was the most abundant EDC in the influent samples. Second group of compounds at high influent levels were alkyl phenols. Pesticide levels of all three WWTP influent samples were low. Pasakoy Advanced WWTP is more effective at eliminating EDCs. Kadikoy Primary WWTP exhibits the lowest EDC elimination efficiencies. To the best of our knowledge, this work comprises the first detailed report on the occurrence and behaviour of both natural and synthetic EDCs in WWTPs of Istanbul and Turkey. The steroid estrogen levels of this study are higher than the previously documented values, except the levels given for Gaobeidian WWTP in Beijing, China. This is attributed to higher population densities of Beijing and Istanbul and as well as to lower individual water consumption rates in the two cities.

A coup attempt against the government took place in Turkey on July 15, 2016. This attempt caused serious injuries and deaths in the country. In this study, the data of patients referred to all hospitals in Istanbul during the attempt were evaluated, and differences between natural disasters, other terrorist actions, and coup attempts were analyzed. In total, 1104 patients were injured in the abovementioned coup attempt. In this study, the demographic and health information of 882 coup victims who were admitted to all hospitals (state and private) in Istanbul on July 15 and 16, 2016 and registered at the Crisis Center of Istanbul Provincial Health Directorate was analyzed. Of the 882 patients evaluated, 97.27% were male and 2.73% were female. The mean age of the patients was 34.12 years. Most (82.43%) patients were admitted to state hospitals, and 17.57% were admitted to private hospitals. The total mortality rate due to the abovementioned coup attempt was 10.4% (9.76% in state hospitals and 13.54% in private hospitals). Of the 882 patients evaluated, 65.07% had gunshot injuries, 11.11% had been assaulted, 7.70% had experienced tank/motor vehicle accidents, 5.44% had other penetrating injuries, 5.32% had soft-tissue trauma, 2.83% had experienced falls (including falls from heights), 0.33% had psychiatric disorders, and 2.15% were admitted for other reasons. The patterns of injury and mortality resulting from the July 15, 2016 coup attempt differed from those resulting from natural disasters and terrorist acts and were similar to those encountered during wars: the victims were predominantly male, similar to those in wars. Following a coup attempt, an increase in the number of patients with post-traumatic stress disorder can be expected. Further studies focusing on the incidence of this disorder due to the abovementioned coup attempt in Turkey are needed. Hospital disaster plans need to include information and plans related to terrorist acts, such as coup attempts.

Objectives: Although several detailed studies concerning the patient profile and clinical features of oral lichen planus have been undertaken all over the world in different populations, a similar study has not yet been conducted in a Turkish population. The purpose of this retrospective study was to describe the demographic and clinical characteristics of a group of patients with oral lichen planus in Turkey. Study Design: Charts of 370 patients, from the archive of Oral Diagnosis and Radiology Department of Marmara University Faculty of Dentistry (Istanbul, Turkey), with histologically confirmed clinical diagnosis of oral lichen planus in the period 1990-2010 were retrospectively reviewed. Results: Of the 370 patients, 260 (70.3%) were women and 110 (29.7%) were men. The mean age was 49.84±13.41 years (range of 16-83). The lesions were asymptomatic in 63 patients (17%). Nearly half of the patients (47.6%) had multiple sites of involvement. Predominantly red forms were the most frequent, affecting 60.5% of patients. Approximately 17% of the patients had symptoms of possible extraoral involvement. No evidence suggesting a connection between oral lichen planus and tobacco or alcohol use was found. Only one out of the 370 cases had histologically proven malignant transformation. Conclusions: The patient profile and clinical features of oral lichen planus in Turkey were generally similar to those described in other populations. The preponderance of the red forms and also the fact that majority of patients referred themselves to our clinic highlighted the lack of awareness among Turkish health care providers about lichen planus. Key words:Oral lichen planus, clinical features, patient profile. PMID:23524413

After the 1999 earthquakes in Turkey several changes in the insurance sector took place. A compulsory earthquake insurance scheme was introduced by the government. The reinsurance companies increased their rates. Some even supended operations in the market. And, most important, the insurance companies realized the importance of portfolio analysis in shaping their future market strategies. The paper describes an earthquake loss assessment methodology that can be used for insurance pricing and portfolio loss estimation that is based on our work esperience in the insurance market. The basic ingredients are probabilistic and deterministic regional site dependent earthquake hazard, regional building inventory (and/or portfolio), building vulnerabilities associated with typical construction systems in Turkey and estimations of building replacement costs for different damage levels. Probable maximum and average annualized losses are estimated as the result of analysis. There is a two-level earthquake insurance system in Turkey, the effect of which is incorporated in the algorithm: the national compulsory earthquake insurance scheme and the private earthquake insurance system. To buy private insurance one has to be covered by the national system, that has limited coverage. As a demonstration of the methodology we look at the case of Istanbul and use its building inventory data instead of a portfolio. A state-of-the-art time depent earthquake hazard model that portrays the increased earthquake expectancies in Istanbul is used. Intensity and spectral displacement based vulnerability relationships are incorporated in the analysis. In particular we look at the uncertainty in the loss estimations that arise from the vulnerability relationships, and at the effect of the implemented repair cost ratios.

New medical schools have been opened in the eastern and southeastern regions of the country. They are also in great need of basic medical science teachers. However, due to security reasons over the past two decades, teachers from the established universities do not desire to travel to these medical schools for lectures. The objective of this study was to develop a synchronous classroom conferencing system to teach basic science courses between two general purpose technology enhanced classrooms of two different universities--Istanbul University (IU) and Istanbul and Harran University (HU), Urfa--located 1,500 miles apart in Turkey. I videostreamed the instructor, content from document camera, Power Point presentations at IU, and the students at both places, IU and HU. In addition, I synchronously broadcast two whiteboards by attaching two mimio devices to the two blackboards in the IU classroom to capture and convert everything written or drawn on them into broadcasting over the intranet. This technique is called "boardcasting," which allows users to stream ink and audio together over the Internet or intranet live. A total of 260 students at IU and 150 students at HU were involved. Off-campus HU students also have asynchronous access to the stored lecture video materials at any time. Midterm and final examinations were administered simultaneously using the same questions at both sites in two universities under the observation of the teaching faculty using the very same system. This system permitted interaction between the students in the class at IU and remote-campus students at HU and the instructor in real time. The instructors at IU were able to maintain a significant level of spontaneity in using their multimedia materials and electronic whiteboards. The mean midterm and final exam scores of students at both universities were similar. The system developed in this study can be used by the medical faculty at the main teaching hospitals to deliver their lectures in real time to the medical students when they are on placement in general practices, ambulatory clinics, and district hospitals in rural areas or to the students of other medical schools. This is an efficacious system in developing countries where availability of high-speed networks and cost of communication are major concerns.

Protracted chemotherapy regimens are new treatment modalities used to treat patients with cancer. These treatments are preferred because of the ease of administration and limited side effects in the outpatient setting. Sixty patients were treated with continuous infusion chemotherapy via implanted infusion ports at Marmara University Hospital Outpatient Chemotherapy Unit in Istanbul, Turkey, from January 2000 to December 2001. Although usage of Huber needles for central venous catheters was limited to between 48 and 72 hours, needles were not removed unless there were signs of inflammatory reaction. The needles remained in place for 28 days (1-49 days) on average. No catheter infections, signs of local irritation, or thrombus formation were observed despite prolonged stay of the Huber needles. Huber needles can be left in place up to several weeks without any untoward effects as long as proper aseptic technique is used.

2013-01-01

Studies on dental units (DUs) are conducted either for the prevention or the reduction of the density of bacterial contamination in dental unit waterlines (DUWLs). However, the existence of fungi in the these systems requires more attention. During dental treatment, direct contact with water contaminated with fungi such as Candida, Aspergillus, or inhalation of aerosols from high-speed drill may cause various respiratory infections, such as asthma, allergies, and wounds on mucose membranes, especially on immunocompromised patients and dentists. The aims of this study are to investigate the number and colonization of fungi in DUWLs in the city of Istanbul, Turkey. Water samples were collected from air-water syringes, high-speed drills, and inlet waters from 41 DUs. The aerobic mesophilic fungi count in high- speed drills was higher than inlet waters and air-water syringes. Non-sporulating fungi were found in 7 DUs. The isolated fungi were identified as Penicillium waksmanii, Cladosporium spp., Penicillium spp., Candida famata, Cryptococcus laurentii, Candida guilliermondii, Penicillium verrucosum, Aspergillus pseudoglaucus, Penicillium decumbens, and Acremonium sp. Some of these fungal genera are known as opportunistic pathogens that led to respiratory diseases such as allergic rhinits. This study shows the importance of regular control of mycological contamination on water at DUs. PMID:24516467

Objective The purpose of this study was to determine the awareness of pharmacists about autism, and their knowledge and attitude towards autism. Setting İstanbul Province of Turkey. Method This descriptive study was carried out in pharmacists working in Istanbul Province of Turkey in 7 municipalities out of 39. One hundred forty-one out of 150 pharmacists who agreed to participate in our study were interviewed with the help of questionnaires. Main outcome measure Knowledge about childhood ASD and the social characteristics thereoff amongst pharmacists. Results Minimum 33.4 and maximum 73.1 % of the pharmacists gave correct answers to each question. Furthermore pharmacists' knowledge about causative factors of childhood ASD proved to be lacking and they tend to believe in outdated theories. The percentage of pharmacists believing that autism holds social stigma in this community was 66.0 %. Conclusion Pharmacists' knowledge regarding ASD needs to be improved. Enhancing their awareness, especially about basic social characteristics of childhood ASD will help pharmacists direct families of children with ASD to responsible health authorities.

Home advantage in Turkish professional soccer.

Seçkin, Aylin; Pollard, Richard

2008-08-01

Home advantage is known to play an important role in the outcome of professional soccer games and to vary considerably worldwide. In the Turkish Super League over the last 12 years, 61.5% of the total points gained have been won by the home team, a figure similar to the worldwide average and to the Premier League in England. It is lower (57.7%) for games played between teams from Istanbul and especially high for games involving teams from cities in the more remote and ethnically distinct parts of Turkey (Van and Diyarbakir). Match performance data show that although home teams in Turkey take 26% more shots at goal than away teams, the success rates for shots do not differ. For fouls and disciplinary cards, home and away teams do not differ significantly in Turkey, a finding that differs from games in England, perhaps due to less referee bias.

Two Observatories in Istanbul: from the Late Ottoman Empire to the Young Turkish Republic

NASA Astrophysics Data System (ADS)

Benoist, Christophe

From the 17th century onward, the Ottoman Empire entered a phase of weakening, as a consequence of many factors including the dissolution of political stability, the loss of territory and decreasing revenue. In the second half of the 19th century, as an attempt to reinforce power of the central authority, the Ottomans undertook major reforms, called Tanzimat. During this period, individuals started to establish professional and learned associations similar to those in the West which eventually led to the creation of a Faculty of Science and to the Ottoman University (Darulfünun, 1900). In this context of reform and opening to the West, the Imperial Observatory (Rasathane-i Amire) was founded in 1868 with the support of France. Its primary aim was to exchange data between European and Ottoman meteorological stations. The Imperial Observatory occupied several locations before reaching its final setting in Kandilli (1911), on the Asian side of the Bosphorus where other activities were developed such as seismology, astronomy, meteorology and magnetic studies. Following the spirit of the newly founded Republic in 1923, a serious reform of the academic programmes and a purging of the staff of the Ottoman University led to the establishment of the Istanbul University in the historical quarter of Beyazit (1933). The Istanbul Astronomical Observatory was founded in the same year and its construction started in 1935. The university reform was largely influenced by the presence of German and other European scholars, many of them Jewish, escaping from Nazi persecution. In particular, Erwin Finlay-Freundlich from Potsdam Observatory became the first director of Istanbul Observatory. Kandilli and Istanbul University observatories are briefly presented here, stressing the main steps of their creation and their astronomica] heritage.

Influenza is a public health problem that affects 5-20% of the world population annually causing high morbidity and mortality especially in risk groups. In addition to determining prevention and treatment strategies with vaccines and antivirals, surveillance data plays an important role in combat against influenza. Surveillance provides valuable data on characteristics of influenza activity, on types, sub-types, antigenic properties and antiviral resistance profile of circulating viruses in a given region. The first influenza surveillance was initiated as a pilot study in 2003 by now named National Influenza Reference Laboratory, Istanbul Faculty of Medicine. Surveillance was launched at national level by Ministry of Health in 2004 and two National Influenza Laboratories, one in Istanbul and the other in Ankara, have been conducting surveillance in Turkey. Surveillance data obtained for nine consecutive years, 2003-2012, by National Influenza Reference Laboratory in Istanbul Faculty of Medicine have been summarized in this report. During 2003-2012 influenza surveillance seasons, a total of 11.077 nasal swabs collected in viral transport medium were sent to the National Influenza Reference Laboratory, Istanbul for analysis. Immun-capture ELISA followed by MDCK cell culture was used for detection of influenza viruses before 2009 and real-time RT-PCR was used thereafter. Antigenic characterizations were done by hemagglutination inhibition assay with the reactives supplied by World Health Organization. Analysis of the results showed that influenza B viruses have entered the circulation in 2005-2006 seasons, and have contributed to the epidemics at increasing rates every year except in the 2009 pandemic season. Influenza B Victoria and Yamagata lineages were cocirculating for two seasons. For other seasons either lineage was in circulation. Antigenic characterization revealed that circulating B viruses matched the vaccine composition either partially or totally for only three seasons. Influenza A(H1N1) and A(H3N2) subtypes were in circulation since the beginning of the surveillance in 2003-2004 season either alone or in cocirculation. After the 2009 pandemic, A(H1N1) viruses were replaced by A(H1N1)pdm09. A(H1N1) and A(H1N1)pdm09 viruses matched the vaccine composition for all seasons. However, A(H3N2) viruses matched the vaccine composition in only three out of eight seasons. Analysis of the data revealed that, (a) influenza season has extended in Turkey and it lasts through May; (b) influenza peaks in different age groups depending on the season; (c) every year a different influenza type and subtype dominates the season; (d) influenza B has been circulating with increasing rate especially in the past six seasons. Influenza surveillance provides valuable data that can guide policy makers in developing programmes to prevent and reduce influenza burden. Therefore, addition of hospital based surveillance to general practice based sentinel surveillance will take influenza surveillance one step ahead in meeting the need for collecting data on severe influenza cases which will allow assessment of burden of influenza more reliably.

Information on high-risk drug use in Turkey, particularly at the regional level, is lacking. The present analysis aims at estimating high-risk cannabis use (HRCU) and high-risk opiate use (HROU) in the cities of Ankara, Istanbul and Izmir. Capture-recapture and multiplier methods were applied based on treatment and police data stratified by age and gender in the years 2009 and 2010. Case definitions refer to ICD-10 cannabis (F.12) and opiate (F.11) disorder diagnoses from outpatient and inpatient treatment records and illegal possession of these drugs as recorded by the police. High-risk cannabis use was estimated at 28 500 (8.5 per 1000; 95% confidence interval 7.3-10.3) and 33 400 (11.9 per 1000; 95% confidence interval 10.7-13.5) in Ankara and Izmir, respectively. Using multipliers based on capture-recapture estimates for Izmir, HRCU in Istanbul was estimated up to 166 000 (18.0 per 1000; range: 2.8-18.0). Capture-recapture estimates of HROU resulted in 4800 (1.4 per 1000; 95% confidence interval 0.9-1.9) in Ankara and multipliers based on these gave estimates up to 20 000 (2.2 per 1000; range: 0.9-2.2) in Istanbul. HROU in Izmir was not estimated due to the low absolute numbers of opiate users. While HRCU prevalence in both Ankara and Izmir was considerably lower in comparison to an estimate for Berlin, the rate for Istanbul was only slightly lower. Compared with the majority of European cities, HROU in these three Turkish cities may be considered rather low.

Earthquake risk communication as dialogue - insights from a workshop in Istanbul's urban renewal neighbourhoods

Ickert, Johanna; Stewart, Iain S.

2016-05-01

An important paradox of hazard communication is that the more effectively a potential physical threat is made public by the scientist, the more readily the scientific message becomes normalized into the daily discourses of ordinary life. As a result, a heightened risk awareness does not necessarily motivate personal or collective preparedness. If geoscientists are to help at-risk communities adopt meaningful measures to protect themselves, new strategies are needed for public communication and community engagement. This paper outlines an attempt to develop a novel approach to train geoscientists, using doctoral and post-doctoral researchers in an EU integrated training network studying tectonic processes and geohazards in Turkey. An urban field visit to seismically vulnerable neighbourhoods in Istanbul allowed the researchers to meet with local residents facing the seismic threat. Those meetings exposed the complex social, political and cultural concerns among Istanbul's at-risk urban communities. These concerns were used to provoke subsequent focus group discussions among the group of geoscientists about roles, responsibilities and methods of communicating hazard information to the public. Through the direct testimony of local residents and geoscientists, we explore the form that new strategies for public communication and community engagement might take.

The aim of this study was to reveal doctors' and nurses' attitudes to euthanasia in intensive care units and surgical, internal medicine and paediatric units in Turkey. A total of 205 doctors and 206 nurses working in several hospitals in Istanbul participated. Data were collected by questionnaire and analysed using SPSS v. 12.0. Significantly higher percentages of doctors (35.3%) and nurses (26.6%) working in intensive care units encountered euthanasia requests than those working in other units. Doctors and nurses caring for terminally ill patients in intensive care units differed considerably in their attitudes to euthanasia and patient rights from other health care staff. Euthanasia should be investigated and put on the agenda for discussion in Turkey.

Components and quantity of street dust are environmental pollution indicators especially in big cities. Street dust is generally composed of car exhaust gas originated particles and wind-transported particles. Heavy metals, which are found in street dust, such as Pb, Cu, Mn, Zn, Cd and Ni are significant for environmental pollution. According to the kind of vehicle in traffic, quantity and type of heavy metals vary in street dust. The use of leaded gasoline gives a boost to the importance of lead level especially in street dust even at the start of 21st century. These metals possess bioaccumulation property, and the possibility of the amount of these metals reaching a critical value and threatening human health increases the importance of this issue. In this study, street dusts have been collected from E-5 Highway from Topkapi to Avcilar regions that spans about 18 km in Istanbul, Turkey, and Pb, Cu, Mn, Zn, Cd and Ni concentrations have been detected in street dust. Twenty-two street dust samples were taken from a total of 22 different points at previously decided 14 main areas. Analyses were conducted using Leeds Public Analyst method. According to the results of this study, Pb, Cu and Zn concentrations in E-5 Highway between Topkapi and Avcilar region in Istanbul were higher than maximum concentration levels of these heavy metals in normal soil. This situation indicates that there is heavy metal pollution in the inspected area in E-5 Highway in Istanbul.

High occurrence of cyclosporiasis in Istanbul, Turkey, during a dry and warm summer

2010-01-01

We evaluated the incidence of Cyclospora cayetanensis in immunocompetent, diarrheic patients during the summers of 2006-2009 in Istanbul. Stools from 1876 patients were examined using microscopic techniques. Cyclospora oocysts were observed in wet preparations by light and epifluorescence microscopy and in fecal smears that were stained by Kinyoun's modified acid-fast stain. Characteristic Cyclospora oocysts were observed in 2 patients in 2006, 17 in 2007, and one in 2009. Samples positive for Cyclospora were further analyzed by a single step polymerase chain reaction (PCR) with Cyclospora-specific primers from the ITS-1 region of the genome. The majority of the Cyclospora positive cases (15) were clustered during about 15 days in June 2007, indicating an unusual incidence of cyclosporiasis in this time period. The climatic characteristics of 2007 could have played a role in this high occurrence rate. PMID:20416057

The samples were classified into four groups: (i) various cooked RTE meat and vegetable meals, (ii) various RTE salads, charcuterie, and cold appetizers, (iii) various cooked RTE bakery products (pasta, pastries, pizza, pita, ravioli, etc.), and (iv) any cooked RTE sweets and desserts (pudding, custard, cream, ashura, etc.). The samples were examined for the presence of SEs by 3M Tecra Staph Enterotoxin Visual Immunoassay method, which is a manual enzyme-linked immunosorbent assay method. Among all samples, only 1 (0.019%) RTE meal (vegetable meal with meat) was found to be contaminated with SEs, a good result in terms of staphylococcal food poisoning risk and public health.

We aimed to compare the clinical characteristics and pregnancy outcomes in women who are Syrian refugees and Turkish women who are non-refugees at a maternity center in Istanbul, Turkey. A total of 600 singleton pregnancies who delivered at Sisli Hamidiye Etfal Training and Research Hospital were included in the study. Demographic data, obstetrical history, clinical findings, obstetrical and neonatal outcomes were compared between 300 Syrian refugees and 300 control patients. The Syrian refugee patients were significantly younger than Turkish patients. The percentage of adolescents aged 12-19 years were significantly higher in the Syrian patients (14.3 vs. 5.3 %, p < 0,001). 41.3 % of the refugee patients had no antenatal care. However, this ratio was only 7.7 % for the control group (p < 0.001). Preterm birth rates showed no difference between the groups, however, postterm birth rates were significantly higher in the control group. Low Birthweight (<2500 gr), oligohydramnios, stillbirth and fetal anomaly rates were not different between the two groups. In comparison to non-refugee control patients, refugee women in our study had poor antenatal care but no adverse perinatal outcomes were observed. Further larger multicenter studies may provide more convincing data about obstetric outcomes in the Syrian refugee population as well as adolescent pregnancies in this population.

This paper describes the two mass-casualty, terrorist attacks that occurred in Istanbul, Turkey in November 2003, and the resulting pre-hospital emergency response. A complex, retrospective, descriptive study was performed, using open source reports, interviews, direct measurements of street distances, and hospital records from the American Hospital (AH) and Taksim Education and Research State Hospital (TERSH) in Istanbul. On 15 November, improvised explosive devices (IEDs) in trucks were detonated outside the Neve Shalom and Beth Israel Synagogues, killing 30 persons and injuring an estimated additional 300. Victims were maldistributed to 16 medical facilities. For example, AH, a private hospital located six km from both synagogues, received 69 injured survivors, of which 86% had secondary blast injuries and 13% were admitted to the hospital. The TERSH, a government hospital located 1 km from both synagogues, received 48 injured survivors. On 20 November, IEDs in trucks were detonated outside the Hong Kong Shanghai Banking Corporation (HSBC) headquarters and the British Consulate (BC), killing 33 and injuring an estimated additional 450. Victims were maldistributed to 16 medical facilities. For example, TERSH, located 18 km from the HSBC site and 2 km from the the BC received 184 injured survivors, of which 93% had secondary blast injuries and 15% were hospitalized. The AH, located 9 km from the HSBC site and 6 km from the BC, received 16 victims. The twin suicide truck bombings on 15 and 20 November 2003 were the two largest terrorist attacks in modern Turkish history, collectively killing 63 persons and injuring an estimated 750 others. The vast majority of victims had secondary blast injuries, which did not require hospitalization. Factors associated with the maldistribution of casualties to medical facilities appeared to include the distance from each bombing site, the type of medical facility, and the personal preference of injured survivors.

Head trauma takes place among the leading causes of mortality in children. This study aimed to determine the risk factors of head trauma-related deaths among children younger than 5 years in Istanbul, Turkey. This study was conducted using the records of the Morgue Department of the Council of Forensic Medicine in Istanbul. The records of cases autopsied between 2008 and 2012 were retrospectively investigated. Of all preschool children deaths, 203 head trauma-related deaths were included in the study. Of all, 117 (57.6%) were males and 86 (42.4%) were females. Most cases (107, 52.70%) were between the ages of 12 and 36 months. The most common mechanism of injury was "fall from a height" with 97 cases (47.78%), followed by "traffic accidents" (67, 33%) and "hit by falling objects" (19, 9.35%). Skull fracture was detected in 176 cases (86.69%), of which 81 (46.02%) were characterized with linear fracture. Furthermore, skull fracture was accompanied by 1 or more skeletal bone fracture in 64 cases. Retinal hemorrhage was investigated in 5 cases of suspected physical abuse and only 2 of them showed retinal hemorrhage findings. Obtained findings revealed that fall from a height was the leading cause of death among unnatural deaths in children younger than 5 years. Domestic accident was found to be a significant risk factor in childhood deaths. Traffic fatalities were among leading causes of death in childhood in our country, likewise in all around the world. Children were found to be more vulnerable to traumas when they start to move around with incomplete motor skills. Therefore, education of parents in terms of child supervision and installing safety precautions toward preschool children will be helpful in preventing such injuries. On the contrary to some findings in the literature, more severe lesions were also prominent even in case of short-range falls from a height.

The aim of the study was to evaluate the periodontal health and treatment needs of chronically hospitalized psychiatric patients in Istanbul, Turkey. The subjects' periodontal health was recorded by the CPI (Community Periodontal Index) method. Of the 330 patients examined, 179 (52.5%) were males and 151 (47.5%) females. The mean age of the patients was 49.2 +/- 11.7 years. The majority (61.8%) was diagnosed with schizophrenia and 30.6% diagnosed with mental retardation. The mean length of hospitalization was 16.0 +/- 10.9 years. Healthy periodontal tissues (CPI 0) were found in 8.8% of the subjects. Bleeding on probing (CPI 1) was recorded in 6.3%, and dental calculus (CPI 2) in 51.8% of the subjects. These were determined as the worst findings. Altogether, 33% of the subjects had deep periodontal pockets, 14.2% with at least one 4- to 5-mm pocket (CPI 3), and 18.8% with at least one 6-mm pocket (CPI 4). The stepwise logistic regression analysis, between the final CPI score and seven variables including age, gender, psychiatric diagnosis, length of hospitalization, degree of helplessness, tooth brushing habits and smoking, showed that irregular tooth brushing habits and male gender were significant contributors to having a final CPI score of 2 or more. The regression analysis also showed that tooth brushing habits remained as an explanatory variable in CPI 0 coded subjects; helplessness and psychiatric diagnosis (mental retardation) in CPI 2; tooth brushing habits and psychiatric diagnosis (schizophrenia) in CPI 3; and only helplessness in CPI 4. The present study underlines a considerable need for prevention and treatment of periodontal disease among chronic psychiatric patients in Istanbul. Efforts need to be focused above all on raising this population's awareness of the importance of oral hygiene and on early diagnosis of periodontal problems.

TOROS2 *1Istanbul University, Turkey, kanli@istanbul.edu.tr, 2Geological and Geophysical Institute of Hungary,3MinGeo, Hungary The Ferenc Channel is one of the main irrigation and ship channel in south of Hungary, existing from 1801. The water level is controlled by the Deák Ferenc Sluice in the channel which was constructed in 1875. At that time, the sluice was unique in Europe with its two channels and brick-walls. The west channel was used for controlling the amount of water and the east channel was used for shipping. In the study, before starting to the restoration and reinforcement plannings at the sluice, non-destructive geophysical investigations were executed. In the first stage, ultra-high frequency seismic (80 kHz) and acoustic (5 kHz) investigations of the floor slab were carried out from a boat on the water level. Due to the water level was approximately 2 m, we could use the advantage of the water ensuring very good coupling with seismic sensors for high frequency seismic and acoustic measurements. In the second stage, resistivity measurements were carried out in the eastern part of the sluice which was used as the shipping channel. Three profiles were measured to map the resistivity distribution of the slab. In the third stage, for better understanding the stability conditions of the walls and easy to compare with the data of GPR measurements, the wall of the sluice were investigated by a simple seismic direct wave method using seismic P-waves for mapping seismic velocities. The last stage of the survey was the GPR measurements that were carried out both on the walls and on the slab of the sluice. During the investigation, the channels were empty and without water. The integrated survey and the interpretation of the results showed us that there were some faults, cracks and voids in the slab existed in the whole grossness of the slab and the brick walls were builded from inhomogenous construction material. Integrated geophysical surveys provided optimum solutions for planning restoration and reinforcement work on this ancient and very old building structure.

The so-called coquina defines moderately to hardly amalgamated shell debris by calcium carbonate cement. Even though its some depositional features are similar to intertidal beachrocks and carbonate-cemented dune rocks or eolianites, coquina occurs in shoal environments and is, in some cases, representative of tectonically uplifted coasts when it exposes remarkably above sea-level. In this study (supported financially by the Research Foundation of Çanakkale Onsekiz Mart University under project number COMUBAP: 2011/41), we discuss diagenetic features, radiocarbon age and subsurface geometry of coquina on Black Sea coast of Istanbul, NW Turkey, where such a Late Holocene occurrence has not been recorded so far. Having a visible thickness of 1 m, the coquina beds crop out on a slightly inclined wide beach formed mostly of shell fragments less than 5 cm in size. It contains calcite and aragonite as connective cement and broken or unbroken shells of Donacilla sp., Pecten glaucum and Ostrea edulis together with various foraminifera such as Elphidium macellum Ammonia compacta and coccolithophore Emiliania huxleyi. Radiocarbon ages from four bulk samples yielded calibrated ages ranging between 3.7 and 2.8 ka BP. Electrical resistivity tomography survey along three distinct transects perpendicular to the coastline were carried out in order to understand the thickness of coquina and its subsurface extensions along the beach. The apparent resistivity data were acquired along the survey lines of 21 electrodes with electrode spacing of 2 m, to give a total length of the line of 40 m. Dipole-dipole electrode configuration was used for 9 data levels. Topographic changes at the locations of each electrode points were determined by means of optical leveling technique for a more accurate calculation and interpretation. Apparent resistivity data were inverted by using 2D smoothness-constrained least squares algorithm. Similar electrical resistivity tomograms were obtained for three lines after the inversion process. The 2D resistivity images displayed a depth range of ~ 4.5 m and showed a strong resistivity contrast between coquina beach material (composed of shell fragments) and coquina rocks. Low resistivity values located at the northern lowermost part of tomograms point to seawater saturated material whilst the highest resistivity values indicate coquina beach material, having larger pore spaces between the grains. The northern uppermost parts of the tomograms, having a moderate resistivity range, mark the coquina rocks with a thickness of ~ 1-1.5 m. Additionally, the images also showed that the landward extension of the coquina rocks reaches ~ 22 m.

In 1972, a six point-network was established by General Directorate of Mapping in Gerede-Ismetpasa. This region is relatively quiet segment of western NAF which is creeping along steadily. This network was surveyed by terrestrial techniques in 1972 and 1973. The Ismetpasa Network was re-measured in 1982 and in 1992 by the Geodesy Working Group of Istanbul Technical University. Although the same network (with five points) was observed in 2002 and 2007 by Zonguldak Karaelmas University applying GPS technique, with 1-hour site occupation, the characteristics of movement has not been detected implicitly. This type of movement still raises a question about the accumulation of tectonic movements in the region. Geodesy Department of Kandilli Observatory and Earthquake Research Institute (KOERI) of Bogazici University has been re-surveyed the network by campaign-based static GPS surveying (10-hour site occupation) since 2005. The GPS velocities data coming from geodynamic GPS networks of the crustal deformation studies and the analysis of repeated geodetic observations give us significant information about the elastic deformation. Therefore, data gathered in this study is processed using GAMIT/GLOBK software and analyzed together with previously collected data to obtain velocity field and strain accumulation in the study area.

Suicidal behaviour is related to psychosocial and biological factors. Although suicide is strictly forbidden by the Islamic faith, there are non-confirmed observations of increased suicidality on religious feast days. The objective of the present study was to find out if suicide attempts of youths living in Istanbul increase on religious feast days compared to ordinary and non-religious holidays. We retrospectively analyzed all suicide attempts (N = 2,232) of young people up to 25 years of age seeking support at various hospitals in Istanbul in 2010. The main hypothesis was that the number of suicide attempts would increase during religious feast days. The number of suicide attempts was higher on religious feast days and non-religious holidays except for New Year's Day and International Labour Day than the daily average number of the actual months. Like on ordinary days, more female than male youth (84.9% vs. 15.1%) attempted suicide on feast days. We speculate that changes of the daily rhythm and increased family interaction on feast days and non-religious holidays could lead to unexpected confrontations and disputes instead of the expected positive family climate. This "Broken-Promise Effect" and changes of the daily rhythm could contribute to the observed increased suicidal behaviour.

The aim of this study was to determine the severity of attention deficit hyperactivity symptoms (ADHS) and related psychological and behavioral variables among 10th grade students in Istanbul/Turkey. Cross-sectional online self-report survey conducted in 45 schools in 15 districts Istanbul. The questionnaire included sections about demographic data and use of substances including tobacco, alcohol and drugs. Also ADHS, depression, anxiety, anger and sensation seeking subscales of Psychological Screening Test for Adolescents (PSTA) were used. The analyses were conducted based on the 4938 subjects. Mean ADHS score was higher in females and among those with a lifetime use of tobacco, alcohol and drug, and having self-harming behavior and suicidal thoughts. ADHS score was correlated with depression, anxiety, anger and sensation seeking scores. In univariate covariance analysis (ANCOVA); depression, anxiety, anger, sensation seeking, lifetime alcohol use and suicidal thoughts predicted the severity of ADHS. The findings suggest that, since ADHS is associated with depression, anxiety, anger, sensation seeking, lifetime alcohol use and suicidal thoughts among 10th grade students, clinicians should screen suicidality and comorbid psychiatric symptoms routinely in adolescents with ADHS.

Studies have examined university students' fear of crime focusing on the relationship between the fear of sexual assault and fear of other crimes, termed the shadow of sexual assault hypothesis; however, no study to date has examined the shadow thesis in a Turkish context. Drawing on the shadow thesis, using a sample of 723 university students in Istanbul, this study focuses on the effect of fear of sexual assault and perceived risk of crime to general fear of crime among university students in Istanbul. Also, the predictors of fear of crime are explored to examine the relationship between lifestyle characteristics, constrained behaviors, and fear. The findings of the study supported the shadow thesis, indicating that fear of sexual assault shaped the nonsexual crimes, especially crimes involving face-to-face confrontations between the victim and offender. Furthermore, lifestyle characteristics are correlated with the men's fear of nonsexual crimes, particularly fear of robbery, aggravated assault, and burglary home.

To determine the histopathological effect of estrogen deficiency and hormone replacement treatment on laryngeal tissue in ovariectomized rats. Animal study. The study was conducted at the animal experiment laboratory of Marmara University School of Medicine, Istanbul, Turkey. Six-month-old female Wistar albino rats were divided into the following 3 groups (n = 8 per group): sham-operated control, ovariectomized, and ovariectomized with estrogen replacement. Rats in the ovariectomized with estrogen replacement group received 17 β-estradiol valerate (200 µg/kg, subcutaneously) once a week. Animals were killed after 8 weeks of intervention. Significant changes were observed in the ovariectomized group when edema in lamina propria, inflammation in squamous, respiratory epithelia and lamina propria, pseudostratification, and cilia loss were assessed. Except cilia loss, there were no significant differences in the assessments between the sham-operated control and ovariectomized with estrogen replacement groups. On the basis of histopathological evaluations, it was shown that estrogen replacement helped to improve laryngeal changes due to experimentally induced menopause.

Current and efficiency optimization under oscillating forces in entropic barriers

Nutku, Ferhat; Aydıner, Ekrem

2016-09-01

The transport of externally overdriven particles confined in entropic barriers is investigated under various types of oscillating and temporal forces. Temperature, load, and amplitude dependence of the particle current and energy conversion efficiency are investigated in three dimensions. For oscillating forces, the optimized temperature-load, amplitude-temperature, and amplitude-load intervals are determined when fixing the amplitude, load, and temperature, respectively. By using three-dimensional plots rather than two-dimensional ones, it is clearly shown that oscillating forces provide more efficiency compared with a temporal one in specified optimized parameter regions. Furthermore, the dependency of efficiency to the angle between the unbiased driving force and a constant force is investigated and an asymmetric angular dependence is found for all types of forces. Finally, it is shown that oscillating forces with a high amplitude and under a moderate load lead to higher efficiencies than a temporal force at both low and high temperatures for the entire range of contact angle.

The purpose of this study is to test the applicability of k0-INAA method at the Istanbul Technical University TRIGA Mark II research reactor. The neutron spectrum parameters such as epithermal neutron flux distribution parameter (α), thermal to epithermal neutron flux ratio (f) and thermal neutron flux (φth) were determined at the central irradiation channel of the ITU TRIGA Mark II research reactor using bare triple-monitor method. HPGe detector calibrations and calculations were carried out by k0-IAEA software. The α, f and φth values were calculated to be -0.009, 15.4 and 7.92·1012 cm-2 s-1, respectively. NIST SRM 1633b coal fly ash and intercomparison samples consisting of clay and sandy soil samples were used to evaluate the validity of the method. For selected elements, the statistical evaluation of the analysis results was carried out by z-score test. A good agreement between certified/reported and experimental values was obtained.

The aim of this study was to determine the effects of life-time tobacco, alcohol, and substance use on psychological and behavioral variables among 10th grade students in Istanbul/Turkey. This study employed a cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire featured a section about use of substances, including tobacco, alcohol, and drugs. The depression, anxiety, anger, assertiveness, sensation seeking and impulsiveness subscales of the Psychological Screening Test for Adolescents (PSTA) were used. The analyses were conducted based on 4957 subjects. Logistic regression analyses were conducted with each school with the related and behavioral variables as the dependent variables. Gender, tobacco, alcohol, and drug use being the independent variables. All four independent variables predicted the dependent variables. Lifetime tobacco and drug use had significant effects on all the subscale score, whereas lifetime alcohol use had significant effects on all the subscale scores other than lack of assertiveness, and male gender was a significant covariant for all the subscale scores. Drug use showed the highest effect on dependent variables. Interaction was found between effects of tobacco and alcohol on anxiety, whereas interactions were found between effects of tobacco and drugs on lack of assertiveness and impulsiveness. The findings suggested that male students with lifetime tobacco, alcohol or drug use have particularly high risk of psychological and behavioral problems. The unique effects of substance clusters on these problems may be useful in developing secondary preventive practices for substance use and abuse problems in Istanbul.

A one-year active surveillance study was conducted to investigate the epidemiological and microbiological characteristics of invasive group A streptococci (GAS) infections in Turkey and to provide data for the establishment of national preventive strategies related to invasive GAS infections. A total of 46 clinical microbiology laboratories from 12 different regions of Turkey (Istanbul; Eastern and Western Marmara; Eastern and Western Blacksea; Aegean; Mediterranean; Western, Central, Northeastern, Middle-eastern and Southeastern Anatolia) participated in the study. Accordingly, GAS strains isolated from sterile body sites (blood, cerebrospinal, synovial, pleural, peritoneal, pericardial fluids) in the study centers between June 2010-June 2011, were sent to Maltepe University Hospital Clinical Microbiology Laboratory for microbiological confirmation and further analysis. The isolates were identified by conventional methods, and for serotyping, opacity factor (OF) and T protein types were investigated. For genotyping GAS lysate preparation, emm gene amplification and sequencing were performed by using the protocols recommended by Centers for Disease Control and Prevention. A total of 65 invasive GAS strains were isolated in 15 of the participant centers, during the study period. The rate of invasive GAS isolation exhibited regional variation, with the highest rates in the Eastern Blacksea (Trabzon, n= 19), followed by Istanbul (n= 17) and Western Anatolia (Ankara, Konya, n= 14). Of the patients with invasive GAS infection 33 were female, 32 were male, with the age range of 0-89 years. GAS strains were most commonly isolated from soft tissue specimens (n= 18), followed by abscess material (n= 10), sterile body fluids (n= 8) and blood (n= 7) samples. Serotyping revealed that 55% (36/65) of the strains were OF positive, and the majority of T protein was polygroup T (n= 20), followed by U (n= 14), B (n= 5), X (n= 3) and Y (n= 2). T protein was not detected in 22 isolates. The strains were found to have 17 different emm types;emm1 (n= 13), emm4 (n= 6), emm6 (n= 6), emm12 (n= 6), emm24 (n= 4), emm14 (n= 3) and emm28 (n= 3). Nine of the strains could not be typed by sequencing. The correlation between emm typing and serotyping was detected as 58%. It was observed that 26-valent vaccines included 70.5% of the invasive GAS strains included in this study. Our study provided initial data concerning the epidemiological properties of invasive GAS infections and characterization of GAS strains in Turkey. The incidence of invasive GAS infections is low in our country. Although immunization programme by 26-valent GAS vaccine is not currently an urgent public health issue for our country, the results of this study indicated that emm types 4 and 24 should better be included in such a vaccine to be used in Turkey. Additionally, since epidemiological features of GAS infections and the microbiological characteristics of the strains can vary by time, for the diagnosis of invasive streptococcal infections and to take the necessary preventive measures, epidemiological studies should be conducted repeatedly.

In Turkey, the cultural structure effects the gender roles in the society, and women are subject to violence in an intense manner both inside the family and in their workplaces. In nursing, which is still defined as a woman's job in our country, it is possible to encounter many aggressive and threatening behaviours. Knowing no geographical borders, aggression leads to dissatisfaction and alienation with the profession for the nurses working at the psychiatric institutions in Turkey, thus aggression is a significant health risk in physical, psychological and social dimensions. The research was carried out with 162 randomly selected nurses working in the psychiatric institutions in Istanbul using the Attitudes Toward Patient Physical Assault Questionnaire. It has been determined that nurses' rate of exposure to verbal/physical assault by the patients and their relatives is high and that they experience an intense uncertainty and conflict, especially in legal issues, and that the duration of working in the psychiatry clinics effects attitudes toward the assaults. It is concluded that the nurses working at the psychiatry clinics in Turkey are under risk in regards to safety and they need protection and support, both in emotional and in legal terms.

Melting bones: The social construction of postmenopausal osteoporosis in Turkey.

2011-11-01

The increased medicalization of different life stages, including menopause, is a subject studied mostly in the Western context. Examining medicalization in the non-Western world advances discussions of body, identity and health. In this paper, I analyze the discourses around postmenopausal osteoporosis in Turkey, focusing on the different constructions of risk in the medical and popular literature. The empirical basis of the paper draws on ethnographic research done in Istanbul, Turkey between June 2006 and March 2007. The research includes participant observation in gynecology clinics, interviews with clinicians and menopausal women and archival research on the representations of menopause in the Turkish media between 1999 and 2006. Referred to as kemik erimesi (melting of the bones) in colloquial Turkish, osteoporosis has been an essential component in the medicalization of menopause in Turkey. I argue that postmenopausal osteoporosis is defined as a combination of embodied risk, which is related to the definition of menopause as a risky period, and lifestyle risk, demonstrated in discussions around "traditional" vs. "modern" clothing and healthcare habits. The Turkish example emphasizes the importance of local conditions in defining medical risk and complicates the embodied vs. lifestyle risk categories. Copyright © 2011 Elsevier Ltd.

To thrive in this era of global competition, all organizations must explore new managerial approaches to get an edge in the marketplace. One increasingly appealing approach is outsourcing. Hospitals are particularly fertile environments for outsourcing, given their role as providers of a broad and complex array of services, many of which may be bought from other institutions. The purpose of this study is to determine the types of services that hospitals in Turkey buy from other organizations. The study sample included 14 university hospitals, 20 Ministry of Health Hospitals, 15 Social Insurance Organization Hospitals and 31 private hospitals in Istanbul, Ankara, Izmir, Antalya, and Eskisehir, which are the biggest cities in Turkey. The following services were found to be outsourced: hospital management information systems (83.8%), cleaning services (81.3%), maintenance services (72.5%), leased medical devices (75.0%), food services (60.0%), patient direction services (63.8%), magnetic imaging services (60.0%), other imaging services (48.8%), laboratory services (42.5%), security services (38.8%), laundry services (36.3%), patient transportation services (33.8%), accounting services (26.3%), ambulance services (22.5%), patient satisfaction measurement services (13.8%), consultancy services (12.5%), and financial and investment services (9.5%). Private hospitals bought more services than public facilities did. The sampled hospitals chose to outsource services in order to decrease costs (78.8%), increase the quality of services rendered (65.5%), increase flexibility and share risk (36.6%), and increase profits (11.2%). The results of this study suggest that outsourcing, when applied judiciously through cost and risk analysis, is a cost-effective approach that can be used by most hospitals.

Recent advances in contemporary Virtual Reality (VR) technologies are going to have a significant impact on veryday life. Through VR it is possible to virtually explore a computer-generated environment as a different reality, and to immerse oneself into the past or in a virtual museum without leaving the current real-life situation. For such the ultimate VR experience, the user should only see the virtual world. Currently, the user must wear a VR headset which fits around the head and over the eyes to visually separate themselves from the physical world. Via the headset images are fed to the eyes through two small lenses. Cultural heritage monuments are ideally suited both for thorough multi-dimensional geometric documentation and for realistic interactive visualisation in immersive VR applications. Additionally, the game industry offers tools for interactive visualisation of objects to motivate users to virtually visit objects and places. In this paper the generation of a virtual 3D model of the Selimiye mosque in the city of Edirne, Turkey and its processing for data integration into the game engine Unity is presented. The project has been carried out as a co-operation between BİMTAŞ, a company of the Greater Municipality of Istanbul, Turkey and the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg, Germany to demonstrate an immersive and interactive visualisation using the new VR system HTC Vive. The workflow from data acquisition to VR visualisation, including the necessary programming for navigation, is described. Furthermore, the possible use (including simultaneous multiple users environments) of such a VR visualisation for a CH monument is discussed in this contribution.

The Criminalization of Physicians and the Delegitimization of Violence in Turkey.

PubMed

Can, Başak

2016-01-01

In June 2013, protests that erupted in Gezi Park in Istanbul, Turkey were met with state violence, mobilizing hundreds of native physicians to deliver emergency medical care. Drawing on ethnographic fieldwork in makeshift clinics during these protests, interviews with Gezi physicians and analyses of recent laws restricting emergency care provision, in this article I explore the criminalization of clinical practice through legal and coercive means of the government and the delegitimization of state violence through clinical and expert witnessing practices of physicians. As I show, material, legal, and discursive articulations of the idiom of medical neutrality revolve around the tension between medical praxis as neutrality and medical praxis as political participation. I offer a reconsideration of medical humanitarian and human rights regimes in terms of their consequences for inciting, documenting and restricting state violence.

Ercan, Aydan; Kiziltan, Gul

2014-10-01

This study was designed to identify the practices and knowledge of food handlers about workplace safety in hospital kitchens (four on-premises and eight off-premises) in Istanbul. A kitchen safety knowledge questionnaire was administered and a kitchen safety checklist was completed by dietitians. The mean total scores of the on-premise and off-premise hospital kitchens were 32.7 ± 8.73 and 37.0 ± 9.87, respectively. The mean scores for the items about machinery tools, electricity, gas, and fire were lower in off-premise than on-premise hospital kitchen workers. The kitchen safety knowledge questionnaire had five subsections; 43.7% of the food handlers achieved a perfect score. Significant differences were found in the knowledge of food handlers working in both settings about preventing slips and falls (p < .05). Significant relationships were found between marital status, education level, and kitchen safety knowledge of the food handlers (p < .05). Copyright 2014, SLACK Incorporated.

Seismic hazard in the Istanbul metropolitan area: A preliminary re-evaluation

USGS Publications Warehouse

Kalkan, E.; Gulkan, Polat; Ozturk, N.Y.; Celebi, M.

2008-01-01

In 1999, two destructive earthquakes (M7.4 Kocaeli and M7.2 Duzce) occurred in the north west of Turkey and resulted in major stress-drops on the western segment of the North Anatolian Fault system where it continues under the Marmara Sea. These undersea fault segments were recently explored using bathymetric and reflection surveys. These recent findings helped to reshape the seismotectonic environment of the Marmara basin, which is a perplexing tectonic domain. Based on collected new information, seismic hazard of the Marmara region, particularly Istanbul Metropolitan Area and its vicinity, were re-examined using a probabilistic approach. Two seismic source and alternate recurrence models combined with various indigenous and foreign attenuation relationships were adapted within a logic tree formulation to quantify and project the regional exposure on a set of hazard maps. The hazard maps show the peak horizontal ground acceleration and spectral acceleration at 1.0 s. These acceleration levels were computed for 2 and 10 % probabilities of transcendence in 50 years.

The Figure of Merit in Space (FMS) and Probability Analyses of the Concentrations for Forecasted Transport of Particles using the WRF and HYSPLIT Models over Istanbul for January and July, 2009.

The main focus of this study is to compare the 24 hourly WRF model and HYSPLIT performances to the observations in terms of concentrations using FMS technique and to determine the probabilities of the spread of the modeled concentrations. In this study, 0.25-degree grid size ECMWF operational model data set is used to generate 24-hour forecasts of atmospheric fields by the WRF model. Each daily forecast is started for both 00 UTC and 12 UTC for the months of January and July of 2009. The interested model area is downscaled by the ratio of 3, starting from 9km resolution to the 1km resolution. 45 vertical levels were structured for the 3 nested domains of which Istanbul is centered. After the WRF model was used for these four sets of simulations, the dispersions of particles are analyzed by using HYSPLIT model. 30,000 particulates with the initial delivery of 5,000 particles to the atmosphere are released at 10m over Istanbul. The concentration analyses are performed for the nested domains in the order of one mother domain only, domain 1 and 2, and three nested-domains, which are named as WRFD1, WRFD12, and WRFD123, respectively. The Figure of Merit in Space (FMS) method is applied to the HYSPLIT results, which are obtained from the WRF model in order to perform the space analysis to be able to compare them to the concentrations calculated by ECMWF Interim data. FMS can be counted as the statistical coefficient of this space analysis, so one can expect that high FMS values can show high agreement between observations and model results. Since FMS is a ratio between the intersections of the areas to their union, it is not possible to deduce whether the model over predicts or under predicts, but it is a good indicator for the spread of the concentration in space. In this study, we have used percentage values of FMS for the fixed time as January and July 2009 and for a fixed concentration level. FMS analysis is applied to the three domain structures as defined above, WRFD1, WRFD12, and WRFD123. FMS values are calculated for the threshold value of 1 pgm-3. The FMS results verify that WRF model wind velocity results are in good agreement with ECMWF ERA Interim data for the level of 10m. FMS values show us that probabilities of 13 days are higher than 50% for July average. Whereas, in January, only 4 days pass over 50%. Consequently, this indicate that July model forecasts may give better results than January forecasts. Moreover, we have calculated the probabilities of the concentration spread for both July and January and detected different spreads between 12 UTC and 00 UTC initialization. Therefore, 12 UTC results show higher probabilities than 00 UTC. According to January 00 UTC and 12 UTC model results, dominant direction of particles' spread is southwesterly. Consistently, the higher probability concentrations can be seen in the Black Sea region extending to the Northern neighbors of Turkey with the probability of approximately 20%. We also observed secondary dominant particles dispersion in the northeast direction with the probability of 25% extending to the Northern Aegean Sea and to the coast of Greece. Since Istanbul is the hypothetical origin location of particle release, the highest probability of concentrations is seen in this location. In July, for 00 UTC, the highest probability spread is toward to the south. Because the predominant wind direction in summer is northeasterly in the northwestern part of Turkey, north Aegean and Marmara Seas are affected by particles with 40% chance. Although, for further south, this probability is decreased to 25 to 30%, Central and Western Anatolia and the border of Greece are still at higher risk. As a result, our analyses indicate that if there is an explosion in Istanbul area, high-risk regions depend on the season. If it occurs in winter, the transported hazardous particles might affect the northern part of Turkey and its neighbors, while in summer the southern and western part of Turkey is under the threat. Key words: Turkey, FMS and probability analyses, concentration analysis, WRF, HYSPLIT models.

Landsat View: Istanbul, Turkey

Istanbul has been a bustling trade city for thousands of years. In this 1975 image, taken by Landsat, the city centers on the Golden Horn the estuary that flows into the Bosporus Straight at the center of the scene. Shown in false color, vegetation is red, urban areas are gray, and water appears black. A bridge built in 1973 to connect the Asian and European sides of Istanbul is barely visible. By 2011, Istanbul's population had exploded from 2 to 13 million people, and the city has gone through a dramatic expansion. This Landsat 5 image shows densely packed urban areas stretching along the Sea of Marmara and up the Bosporus Straight where a second bridge built in 1988 now crosses the water. ---- NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013.

Determination of heavy metals in indoor dust from Istanbul, Turkey: estimation of the health risk.

PubMed

Kurt-Karakus, Perihan Binnur

2012-12-01

Levels of eight potentially toxic heavy metals in indoor dust from homes and offices in Istanbul were investigated. The concentrations of heavy metals in indoor dust from homes+office ranged from 62 to 1800 μgg(-1) for Cu, 3-200 μgg(-1) for Pb, 0.4-20 μgg(-1) for Cd, 210-2800 μgg(-1) for Zn, 2.8-460μgg(-1) for Cr, 8-1300μgg(-1) for Mn, 2.4-25μgg(-1) for Co, 120-2600μgg(-1) for Ni. Results of the study were comparable to other studies conducted on indoor dust and street dust from a variety of cities globally. Considering only ingestion + inhalation, the carcinogenic risk level of Cr for adults and children (3.7×10(-5) and 2.7×10(-5)) in Istanbul was in the range of EPA's safe limits (1×10(-6) and 1×10(-4)), indicating that cancer risk of Cr due to exposure to indoor dust in Istanbul can be acceptable. According to calculated Hazard Quotient (HQ), for non-cancer effects, the ingestion of indoor dust appears to be the major route of exposure to the indoor dust that results in a higher risk for heavy metals, followed by dermal contact and inhalation pathways. However, compared to ingestion and dermal contact exposure, exposure through inhalation is almost negligible. Hazard Index (HI) values for all studied elements were lower than safe limit of 1 and this result suggested that none of the population groups would likely to experience potential health risk due to exposure to heavy metals from indoor dust in the study area.

We aim to investigate, as a first insight, the presence and rates of high-risk Escherichia coli ST131 clone in Istanbul and evaluate antimicrobial resistance and CTX-M-15 production of ST131 and non-ST131 isolates. The use of MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass-spectrometry) to detect E. coli ST131 clone is also evaluated. A total of 203 extended-spectrum beta-lactamase (ESBL)-producing urinary isolates from a training hospital in Istanbul were investigated. Detection of E. coli ST131 was done by MALDI-TOF MS and real-time PCR melting curve analysis. The presence of CTX-M and CTX-M-15 beta-lactamases was investigated by PCR and sequence analysis. Of the 203 isolates, 81 (39.9%) and 75 (36.9%) isolates were identified as ST131 clone by PCR and MALDI-TOF MS, respectively. Resistance to ciprofloxacin was significantly higher among ST131 isolates. A total of 169 (83.5%) isolates produced CTX-M beta-lactamase, of which 72 (43%) were CTX-M-15. The production of CTX-M and CTX-M-15 were significantly higher among ST131 isolates. We have demonstrated, for the first time, high rates of ST131 clone among ESBL-producing E. coli isolates in Istanbul, a region with high rates of resistance to third-generation cephalosporins and fluoroquinolones. Further investigation of this high-risk clone and its contribution to high antimicrobial resistance in Turkey is essential. MALDI-TOF MS is a useful tool for detection of high-risk clones and associated resistance patterns, simultaneous to bacterial identification.

In this study, a total of 180 vegetable samples collected from several district bazaars of Istanbul were investigated for the occurrence of Escherichia coli using a culture-based method. The isolates were subjected to real-time PCR detection of Shiga-toxin-producing E. coli (STEC) using primers specific for the Shiga toxin (stx1 and stx2) and intimin (eae) virulence genes. The prevalences of E. coli in the samples were 93·3% in spinach, 93·3% in lettuce, 86·6% in parsley, 43·3% in carrot, 33·3% in cucumber and 13·3% in tomato. Of 180 samples, 13 contained STEC (six parsley, three carrots, three lettuces and one cucumber of 30 samples of each). Among 13 STEC-positive isolates, presence of stx1, stx2 and eae was detected in only one sample, stx2 and eae in two samples, and stx2 in ten samples. Serotype O157 was found in parsley, lettuce and carrot; O26 in lettuce, parsley, cucumber and carrot; and O111 and O113 in parsley only. In conclusion, STEC was present in vegetable samples marketed in several district bazaars in Istanbul; this might represent a route of transmission of pathogenic STEC to humans and be harmful to public health. We assessed the occurrence of virulent Escherichia (E.) coli and Shiga-toxin-producing E. coli (STEC) virulent populations in the vegetable samples collected from several district bazaars in Istanbul, Turkey. The results indicated that the vegetables from the bazaars had poor microbial quality and represented a potential health risk to customers. © 2013 The Society for Applied Microbiology.

Change detection using Landsat images and an analysis of the linkages between the change and property tax values in the Istanbul Province of Turkey.

2017-09-15

In this study, the Istanbul Province was monitored using Landsat 5 TM, MSS, Landsat 7 ETM+, and Landsat 8 OLI imagery from the years 1986, 2000, 2009, 2011, 2013, and 2015 in order to assess land cover changes in the province. The aim of the study was to classify manmade structures, land, green, and water areas, and to observe the changes in the province using satellite images. After classification, the images were compared in selected years to observe land cover. Moreover, these changes were correlated with the property tax values of Istanbul by years. The findings of the study showed that manmade structure areas increased while vegetation areas decreased due to rapid population growth, urbanization, and industrial and commercial development in Istanbul. These changes also explain the transformation of land from rural and natural areas to residential use, and serve as a tool with which to assess land value increments. Land value capturing is critical for the analysis of the linkages between the changes in land cover, and for assessing land transformation and urban growth. Due to inadequate market data, real estate tax values were used to analyze the linkages between detection changes, land cover, and taxation. In fact, the declared tax values of land owners are generally lower than the actual market values and therefore it is not possible to transfer the value increasing of land in urban areas by using property taxation from the owner to local and central governments. The research results also show that the integration of remote sensing results with real estate market data give us to determine the tax base values of real estate more realistically.

ISS032-E-017547 (9 Aug. 2012) --- A nighttime view of Istanbul, Turkey is featured in this image photographed by an Expedition 32 crew member on the International Space Station. Most of Istanbul?s Asian suburbs (right) appear in this night view from the space station, but only about half the area of the city on the European side (left) can be seen. The margins of the metropolitan area are clearly visible at night, more so than in daylight images. The Bosporus strait (also spelled Bosphorus) (center left) famously separates the two halves of the city, and links the small Sea of Marmara (and the Mediterranean Sea to its south) to the Black Sea (indistinguishable in this night view, top right). The strait is 31 kilometers long, most of which is visible in this view. The Bosporus is a very busy waterway, with larger ships passing to and from the Black Sea competing with numerous ferries that cross between the two halves of the city. Apart from the dark Sea of Marmara (lower margin of the image), the other large dark areas are all wooded hills which provide open spaces for the densely populated city of Istanbul ? one of the largest in Europe with 13.5 million inhabitants. The old city occupies the prominent point at the entrance to the strait. Major traffic arteries are the brighter lines crossing the metropolitan area, and also mark all the shorelines. The First Bosporus Bridge and Second Bridge (also known as the Fatih Sultan Mehmet Bridge) can be seen spanning the strait. The brilliant lights of both international airports serving the region also stand out at lower left and lower right.

Wireless technologies for the monitoring of strategic civil infrastructures: an ambient vibration test of the Faith Bridge, Istanbul, Turkey

The monitoring of strategic civil infrastructures to ensure their structural integrity is a task of major importance, especially in earthquake-prone areas. Classical approaches to such monitoring are based on visual inspections and the use of wired systems. While the former has the drawback that the structure is only superficially examined and discontinuously in time, wired systems are relatively expensive and time consuming to install. Today, however, wireless systems represent an advanced, easily installed and operated tool to be used for monitoring purposes, resulting in a wide and interesting range of possible applications. Within the framework of the earthquake early warning projects SAFER (Seismic eArly warning For EuRope) and EDIM (Earthquake Disaster Information systems for the Marmara Sea region, Turkey), new low-cost wireless sensors with the capability to automatically rearrange their communications scheme are being developed. The reduced sensitivity of these sensors, arising from the use of low-cost components, is compensated by the possibility of deploying high-density self-organizing networks performing real-time data acquisition and analysis. Thanks to the developed system's versatility, it has been possible to perform an experimental ambient vibration test with a network of 24 sensors on the Fatih Sultan Mehmet Bridge, Istanbul (Turkey), a gravity-anchored suspension bridge spanning the Bosphorus Strait with distance between its towers of 1090 m. Preliminary analysis of the data has demonstrated that the main modal properties of the bridge can be retrieved, and may therefore be regularly re-evaluated as part of a long-term monitoring program. Using a multi-hop communications technique, data could be exchanged among groups of sensors over distances of a few hundred meters. Thus, the test showed that, although more work is required to optimize the communication parameters, the performance of the network offers encouragement for us to follow this research direction in developing wireless systems for the monitoring of civil infrastructures.

Izmit, Turkey 1999 Earthquake Interferogram

NASA Image and Video Library

2001-03-30

This image is an interferogram that was created using pairs of images taken by Synthetic Aperture Radar (SAR). The images, acquired at two different times, have been combined to measure surface deformation or changes that may have occurred during the time between data acquisition. The images were collected by the European Space Agency's Remote Sensing satellite (ERS-2) on 13 August 1999 and 17 September 1999 and were combined to produce these image maps of the apparent surface deformation, or changes, during and after the 17 August 1999 Izmit, Turkey earthquake. This magnitude 7.6 earthquake was the largest in 60 years in Turkey and caused extensive damage and loss of life. Each of the color contours of the interferogram represents 28 mm (1.1 inches) of motion towards the satellite, or about 70 mm (2.8 inches) of horizontal motion. White areas are outside the SAR image or water of seas and lakes. The North Anatolian Fault that broke during the Izmit earthquake moved more than 2.5 meters (8.1 feet) to produce the pattern measured by the interferogram. Thin red lines show the locations of fault breaks mapped on the surface. The SAR interferogram shows that the deformation and fault slip extended west of the surface faults, underneath the Gulf of Izmit. Thick black lines mark the fault rupture inferred from the SAR data. Scientists are using the SAR interferometry along with other data collected on the ground to estimate the pattern of slip that occurred during the Izmit earthquake. This then used to improve computer models that predict how this deformation transferred stress to other faults and to the continuation of the North Anatolian Fault, which extends to the west past the large city of Istanbul. These models show that the Izmit earthquake further increased the already high probability of a major earthquake near Istanbul. http://photojournal.jpl.nasa.gov/catalog/PIA00557

Taking predictors of hospitalization characteristics into consideration internationally would broaden our understanding of this population on a local basis. We aimed to examine and compare socio-demographic profiles along with hospitalization characteristics including length of hospital stay (LOS), reasons for admission and diagnoses among older adult inpatients hospitalized in Ireland and Turkey, and to assess factors predicting these features. The admission charts of 356 psychiatric inpatients over 65 years of age who were admitted to two different acute psychiatric hospitals (Sligo/Ireland and Istanbul/Turkey) were analysed by means of descriptive modalities and logistic regression. There were significant differences in several domains of socio-demographics, reasons of admission and diagnoses. LOS was significantly longer in Ireland. Living alone was the only significant predictor for longer LOS in both countries, whereas in addition to living alone, younger age was also a contributor for longer LOS in Turkey. Given that the only factor predicting LOS both in Turkey and Ireland was living alone, helping to identify more acceptable ways of providing social support for living arrangements constitutes an important service to shorten LOS in old age psychiatric population. It is possible to infer that independent from the cultural diversities, living arrangement is a consistent entity to influence length of hospital stay in older adult population.

The digital documentation of architectural heritage is important for monitoring, preserving, managing as well as 3B BIM modelling, time-space VR (virtual reality) applications. The unmanned aerial vehicles (UAVs) have been widely used in these application thanks to rapid developments in technology which enable the high resolution images with resolutions in millimeters. Moreover, it has become possible to produce highly accurate 3D point clouds with structure from motion (SfM) and multi-view stereo (MVS), to obtain a surface reconstruction of a realistic 3D architectural heritage model by using high-overlap images and 3D modeling software such as Context capture, Pix4Dmapper, Photoscan. In this study, digital documentation of Otag-i Humayun (The Ottoman Empire Sultan's Summer Palace) located in Davutpaşa, Istanbul/Turkey is aimed using low cost UAV. The data collections have been made with low cost UAS 3DR Solo UAV with GoPro Hero 4 with fisheye lens. The data processing was accomplished by using commercial Pix4D software. The dense point clouds, a true orthophoto and 3D solid model of the Otag-i Humayun were produced results. The quality check of the produced point clouds has been performed. The obtained result from Otag-i Humayun in Istanbul proved that, the low cost UAV with fisheye lens can be successfully used for architectural heritage documentation.

To evaluate the prevalence and aetiology of dental erosion in Greek minority school children living in Istanbul (Turkey). The present study was initiated in four Greek minority elementary schools in Istanbul where a total of 83 children (46 girls, 37 boys) between ages 7-14 years old were examined. Children were categorised into 7-11 and 12-14 ages groups. Data were obtained by clinical examination, questionnaire and standard data records. All tooth surfaces were examined, dental erosion was recorded per tooth and classified according to the index of Lussi et al. [1996] In the 7-11 yrs old group, 47.4% (n:18) of the children exhibited dental erosion while in 12-14 yrs old group, 52.6% (n:20) of the children exhibited dental erosion. There were no statitistical differences between age, gender groups and findings of dental erosion (p>0.05). However prevalence of dental erosion in 12-14 yrs old was twice that of the 7-11 years old children. In general, an unusual drinking pattern of slow swallowing of beverages significantly affected the prevalence of dental erosion (p=0.03). Multiple regression analysis revealed no relationship between dental erosion and related erosive sources such as medical conditions, brushing habits, swimming, and the consumption of acidic fruit juices and beverages (p>0.05). However it should be noted that the sample size in the current study was small.

As result of the Turkey's economic growth and heavy migration processes from rural areas, Istanbul has experienced a high urbanization rate, with severe impacts on the environment in terms of natural resources pressure, land-cover changes and uncontrolled sprawl. As a consequence, the city became extremely vulnerable to natural and man-made hazards, inducing ground deformation phenomena that threaten buildings and infrastructures and often cause significant socio-economic losses. Therefore, the detection and monitoring of such deformation patterns is of primary importance for hazard and risk assessment as well as for the design and implementation of effective mitigation strategies. Aim of this work is to analyze the spatial distribution and temporal evolution of deformations affecting the Istanbul metropolitan area, by exploiting advanced Differential SAR Interferometry (DInSAR) techniques. In particular, we apply the Small BAseline Subset (SBAS) approach to a dataset of 43 TerraSAR-X images acquired, between November 2010 and June 2012, along descending orbits with an 11-day revisit time and a 3 m × 3 m spatial resolution. The SBAS processing allowed us to remotely detect and monitor subsidence patterns over all the urban area as well as to provide detailed information at the scale of the single building. Such SBAS measurements, effectively integrated with ground-based monitoring data and thematic maps, allows to explore the relationship between the detected deformation phenomena and urbanization, contributing to improve the urban planning and management.

Accessibility to public environment is the human right and basic need of each citizen and is one of the fundamental considerations for urban planning. The aim of this study is to determine the compliance of public buildings in central business districts (CBD) of Istanbul, Turkey, to wheelchair accessibility to the guidelines of the instrument and identify architectural barriers faced by wheelchair users. This is a descriptive study of 26 public buildings in CBD of Istanbul. The instrument used is the adapted Useh, Moyo and Munyonga questionnaire to collect the data from direct observation and measurement. Descriptive statistics of simple percentages and means are used to explain the compliance to the guidelines of the instrument and wheelchair accessibility. The descriptive survey results indicate that wheelchair users experience many accessibility problems in public environment of the most urbanised city (cultural capital of Europe in 2010) in a developing country. It is found that the major architectural barrier is the public transportation items with the lowest mean compliance (25%). Beside this, the most compliant to the instrument is entrance to building items with 79% as mean percentage. It is also found that there is an intention to improve accessibility when building construction period is investigated. This article describes the example of the compliance of public buildings accessibility when the country has legislation, but lacking regulations about accessibility for the wheelchair users.

There is an emerging but important literature on the effects of sport events such as soccer on stock market returns. After a soccer team's win, agents discount future events more favorably and increase risk tolerance. Similarly, after a loss, risk tolerance decreases. This paper directly assesses risk tolerance after a sports event by using daily data from the three major soccer teams in Turkey (Beşiktaşç Fenerbahge and Galatasaray). Results provide evidence that risk tolerance increases after a win, but similar patterns were not found after a loss.

Ports and harbors are the major vulnerable coastal structures under tsunami attack. Resilient harbors against tsunami impacts are essential for proper, efficient and successful rescue operations and reduction of the loss of life and property by tsunami disasters. There are several critical coastal structures as such in the Marmara Sea. Haydarpasa and Yenikapi ports are located in the Marmara Sea coast of Istanbul. These two ports are selected as the sites of numerical experiments to test their resilience under tsunami impact. Cargo, container and ro-ro handlings, and short/long distance passenger transfers are the common services in both ports. Haydarpasa port has two breakwaters with the length of three kilometers in total. Yenikapi port has one kilometer long breakwater. The accurate resilience analysis needs high resolution tsunami modeling and careful assessment of the site. Therefore, building data with accurate coordinates of their foot prints and elevations are obtained. The high resolution bathymetry and topography database with less than 5m grid size is developed for modeling. The metadata of the several types of structures and infrastructure of the ports and environs are processed. Different resistances for the structures/buildings/infrastructures are controlled by assigning different friction coefficients in a friction matrix. Two different tsunami conditions - high expected and moderate expected - are selected for numerical modeling. The hybrid tsunami simulation and visualization codes NAMI DANCE, STOC-CADMAS System are utilized to solve all necessary tsunami parameters and obtain the spatial and temporal distributions of flow depth, current velocity, inundation distance and maximum water level in the study domain. Finally, the computed critical values of tsunami parameters are evaluated and structural performance of the port components are discussed in regard to a better resilience.

Approximately 1000 people were killed in the collapse of buildings in Istanbul, Turkey, during the 17 August 1999 I??zmit earthquake, whose epicenter was roughly 90 km east of the city. Most of the fatalities and damage occurred in the suburb of Avcilar that is 20 km further west of the epicenter than the city proper. To investigate this pattern of damage, the U.S. Geological Survey, in cooperation with the Kandilli Observatory and Earthquake Research Institute (KOERI), deployed portable digital seismographs at seven free-field sites in western Istanbul, to record aftershocks during the period from 24 August to 2 September. The primary objective of this deployment was to study the site effects by comparing the aftershock ground motions recorded at sites inside and outside the damaged area, and to correlate site effects with the distribution of the damaged buildings. In addition to using weak-motion data, mainshock and aftershock acceleration records from the KOERI permanent strong-motion array were also used in estimating the site effects. Site effects were estimated using S waves from both types of records. For the weak-motion data set, 22 events were selected according to the criteria of signal-to-noise ratio (S/N ratio) and the number of stations recording the same event. The magnitudes of these events ranged from 3.0 to 5.2. The acceleration data set consisted of 12 events with magnitudes ranging from 4.3 to 5.8 and included two mainshock events. Results show that the amplifying frequency band is, in general, less than 4 Hz, and the physical properties of the geologic materials are capable of amplifying the motions by a factor of 5-10. In this frequency band, there is a good agreement among the spectral ratios obtained from the two mainshocks and their aftershocks. The damage pattern for the 17 August I??zmit earthquake is determined by several factors. However, our study suggests that the site effects in Avcilar played an important role in contributing to the damage.

The understanding of the impurities in natural snow is important in realizing its atmospheric quality, soil characteristics, and the pollution caused to the environment. Knowledge of the occurrence of major ions and trace metals in the snow in the megacity of Istanbul is very limited. This manuscript attempts to understand the origin of major soluble ions (fluoride, acetate, formate, chlorite, chloride, nitrite, chlorate, bromide, nitrate, sulfate, phosphate, and perchlorate) and some trace metals (Fe, Mn, Cd, Co, Ni, Pb, Zn, Cu) in winter surface snow, collected in Istanbul, Turkey. The sampling of the surface snow was conducted after each precipitation during the winter of 2015-2016 at three sites in the city. Besides the statistical evaluation of the major ions, and some trace metal concentrations, the chemical variations along with atmospheric circulations, which are important modification mechanisms that influence the concentrations, were investigated in the study. At examined locations and times, 12 major anions were investigated and in these anions fluoride, chlorite, chlorate, bromide, and perchlorate in the snow samples were below the detection limit; only SO 4 2- , NO 3 - , and CI - were found to be in the range of 1.11-17.90, 0.75-4.52, and 0.19-3.01 mg/L. Also, according to the trace element determination, the concentration was found to be 29.2-53.7, 2.0-16.1, 1.0-2.2, 50.1-71.1, 24.2-35.2, ND-7.9, 43.2-106.6, and 3.0-17.7 μg/L for Fe, Mn, Cd, Co, Ni, Pb, Zn, and Cu, respectively. The major anions and investigated trace elements here originated mainly from anthropogenic and atmospheric circulation and mainly influenced by northerly and southerly circulation patterns. While the main limitations in the present study may be the low number of samples that may not be entirely representative, accurately reflect identification, or support other previously observed local measurements, we believe that the type of data presented in this study has the potential to be used in the field of environmental risk assessment and, as result, for human health.

2001-01-01

Current and future wastewater treatment and disposal strategies of Istanbul city are presented. Istanbul is the largest city of Turkey and has a population of 10 million that may reach about 20 million in 2032. The city is divided into Asian and European sides by the Bosphorus Strait. The Sea of Marmara is an enclosed sea, connected to the Black Sea and Aegean Sea by the straits of Bosphorus and Dardanelles. Therefore, there is very strong and permanent stratification in the Sea of Marmara throughout the year, lower layers carrying Mediterranean and the upper layers carrying Black Sea water. This unique coastal structure of Istanbul necessitated a detailed study to determine the level of wastewater treatment and the location and depth of marine outfalls. A comprehensive three-dimensional water quality modelling study concluded that tertiary treatment including nitrogen and phosphorus removal is required for the effluent discharges into the Marmara Sea. However, enhanced primary or even primary treatment has been found satisfactory for discharges into the lower layers of the Bosphorus and into the Black Sea. Provisions for upgrading to secondary treatment were recommended. The status of existing and planned wastewater treatment plants and sea outfalls of Istanbul city are also presented. Although the amount of treated wastewater was only 63 percent in 1998, a target of 95 percent treatment level by the end of 2000 has been adopted in implementation plans. All treatment plants are located at or close to the coast except Pasakoy WWTP which is in the catchment area of Omerli Reservoir, the major source of drinking water for Istanbul city. The Pasakoy WWTP has been designed to treat wastewaters collected from the catchment area of Omerli Reservoir to tertiary level before ultimate disposal. The implementation programme together with the cost estimates are given. Total investment on water, wastewater and stormwater projects up to year 2032 is estimated at about 10 billion US Dollars. The share of the wastewater projects in this total is increasing with time. The financial analysis concluded that investments for a Higher Demand Scenario can be realised by raising the water tariffs to 1.0 $/m3 for Phase 1 and 0.9 $/m3 for Phase 2.

To identify the characteristics that are associated with depressive symptomatology among Turkish older adults with low income. Depression is a major threat to mental health in older people, but little is known about older adults with low income at risk for depressive symptomatology in Turkey. This was a cross-sectional study, based in one area of Istanbul. The sample included 132 older adults in a rural setting living in Istanbul, Turkey. The participants were 55 years of age or older and chosen from among older adults with low income. Data were collected through a structured interview conducted in the homes of the participants. High depressive symptoms (Geriatric Depression Scale > or =11) were reported by 50% of the participants. Compared with non-depressed individuals, those with depressive symptomatology were more likely to be women, widowed, lack health insurance and to live alone. Depressed participants significantly more often reported chronic health conditions compared to non-depressed participants (OR = 4.11, 95% CI = 1.35, 12.57). Overall well-being scores were significantly higher in men and in the non-depressed group. The result of the Pearson correlation provided support for the association between depression scores and overall well-being scores (r = -0.60). Depressive symptomatology is prevalent within Turkish older adults with low income. Further research is needed to examine potential risk factors associated with depressive symptomatology for this population. Findings may assist health care professionals in assessing high-risk older people who could benefit from interventions aimed at minimizing depressive symptoms.

For more than 35 years, most national immunization programs have established managerial structures and processes for delivering vaccination services to their populations. These days, immunization managers are facing an increasing number of challenges due to the introduction of new vaccines, shifting demographic patterns, complex networks of service providers, and maintaining the gains achieved with previous vaccination efforts. To confront these challenges, better program performance will require better managerial practices, which incorporates new technologies. To that end, the International Association of Immunization Managers (IAIM) is the first global professional association launched to promote superior leadership and management skills among health professionals involved with vaccination efforts worldwide. From 3 to 4 March 2015, approximately 132 members from 70 countries representing six regions, gathered in Istanbul, Turkey for the inaugural conference of IAIM. In the two-day program, members selected thirteen peers to constitute the Governing Council. The 12 articles of the bylaws of the Association were also ratified. This conference was a forum for sharing managerial best practices through networking sessions, breakout sessions, and presentations. Members also learned about IAIM sponsored training opportunities to deepen their managerial competencies through peer-to-peer exchanges and scholarship training programs. We believe that the IAIM inaugural conference was an appropriate platform for equipping managers with tools and professional network of peers to support them in achieving national, regional and global immunization goals, including those of the Global Vaccine Action Plan of the World Health Organization.

The aim of this study was to gather comprehensive data from three hospitals in Istanbul, Turkey, in order to gain in-depth understanding of the quality of antenatal care in this setting. The Bruce-Jain framework for quality of care was adapted for use in evaluating antenatal care. Methods included examination of hospital records, in-depth interviews, exit questionnaires, and structured observations. The study revealed deficiencies in the quality of antenatal care being delivered at the study hospitals in all six elements of the quality-of-care framework. The technical content of visits varied greatly among the hospitals, and an overuse of technology was accompanied by neglect of some essential components of antenatal care. Although at the private hospital some problems with the technical content of care were identified, client satisfaction was higher there, where the care included good interpersonal relations, information provision, and continuity. Providers at all three hospitals felt constrained by heavy patient loads and a lack of resources. Multifaceted approaches are needed to improve the quality of antenatal care in this setting.

This article estimates greenhouse gas emissions and global warming factors resulting from collection of municipal solid waste to the transfer stations or landfills in Istanbul for the year of 2015. The aim of this study is to quantify and compare diesel fuel consumption and estimate the greenhouse gas emissions and global warming factors associated with municipal solid waste collection of the 39 districts of Istanbul. Each district's greenhouse gas emissions resulting from the provision and combustion of diesel fuel was estimated by considering the number of collection trips and distances to municipal solid waste facilities. The estimated greenhouse gases and global warming factors for the districts varied from 61.2 to 2759.1 t CO 2 -eq and from 4.60 to 15.20 kg CO 2 -eq t -1 , respectively. The total greenhouse gas emission was estimated as 46.4E3 t CO 2 -eq. Lastly, the collection data from the districts was used to parameterise a collection model that can be used to estimate fuel consumption associated with municipal solid waste collection. This mechanistic model can then be used to predict future fuel consumption and greenhouse gas emissions associated with municipal solid waste collection based on projected population, waste generation, and distance to transfer stations and landfills. The greenhouse gas emissions can be reduced by decreasing the trip numbers and trip distances, building more transfer stations around the city, and making sure that the collection trucks are full in each trip.

The purpose of this study was to analyze smoking related beliefs, attitudes and knowledge on anti-smoking legislation among physicians practicing in Istanbul, Turkey. Questionnaires were sent to 18.000 physicians who were also members of Istanbul Chamber of Medicine. Three hundred-seventy and four physicians responded. Two hundred-fifty of the respondents were males (66.8%) and 124 were females (33.2%). Sixty out of 374 physicians were smokers. Eighteen of them (30%) were females, 42 of them (70%) were males. 91.5% of physicians who smoked tobacco and 98.4% of non-smoker physicians agreed that smoking is a serious health issue. 91.1% of nonsmoker physicians and 70.7% of smokers asked their patients about their smoking habits. The difference between smokers and non-smokers was statistically significant in both comparisons (p= 0.012 and p= 0.00, respectively). 25% of smoking physicians and 34.5% of non-smokers referred their patients to smoking cessation centers. 21.7% of smoking physicians and 28.8% of non-smokers believed in the success of pharmacological therapy. The difference between smokers and non-smokers was statistically non significant (p= 0.167 and p= 0.262, respectively). This results suggests that physicians have insufficient knowledge on smoking cessation therapies and the law regarding the use of tobacco and that smoking cessation techniques should be incorporated in the curriculum of the faculties and post graduation training programs.

The aim of this study was to determine the injury spectrum and characteristics of people who committed suicide by jumping into water from the July 15th Martyrs Bridge and Fatih Sultan Mehmet Bridges in Istanbul, Turkey. This study included all of the jumpers from the July 15th Martyrs Bridge and Fatih Sultan Mehmet Bridge who were autopsied by the Council of Forensic Medicine, Istanbul Morgue Department, between 2000 and 2013. All of the data were collected from archived case files. Trauma scores were calculated from the traumatic findings of the autopsy reports using the New Injury Severity Score (NISS). A total of 80 jumping suicides were identified. The male-to-female ratio was 9:1, and the mean age was 34.06 ± 9.6 years. Most suicides occurred in 2009. The suicide rates were higher in the winter, particularly in December. The most frequent injuries were skin lesions, rib fractures, and lung lacerations. In 12% of the cases, the trauma was minor (NISS range, 0-14; mean, 7 ± 5.67), and in 88% of the cases, it was major (NISS range, 17-66; mean NISS, 44.5 ± 12.46). The sociodemographic features of the jumpers who committed suicide were quite similar to those reported in previous studies. Preventative measures (installation of barriers or banning pedestrian access to bridges) reduced the suicide rate but were not completely effective. Establishing early warning systems and rescue strategies could save the lives of jumpers who have minor trauma.

Turkey has maintained liberal contraception and abortion policies since the 1980s. In 2012, the government proposed to restrict abortion; a bill limiting abortion was later drafted but never passed into law. Since the proposed restriction, women have reported difficulty accessing abortion services across Turkey. We aimed to better understand the current availability of abortion and reproductive health services in Istanbul and explore whether access to services has changed since 2012. In 2015, we completed 14 in-depth interviews with women and 11 semi-structured interviews with key informants. We transcribed all interviews and completed content and thematic analyses of the data. Key informants had good knowledge about the political discourse and the current abortion law. In contrast, women were familiar with the political discourse but had mixed information about the current status of abortion and were unsure about the legality of their own abortions. There was consensus that access to services has become more limited in the last five years due to the political climate, thus advocacy to prioritize reproductive health services, and abortion care in particular, in the public health system are needed.

We used the results from the first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (2009-2019) and the first organized population-based screening program implemented in a county of Istanbul, Turkey, to assess the potential cost-effectiveness of a population-based mammography screening program in Turkey. Two screening strategies were compared: BMSP (includes three biennial screens for women between 40-69) and Turkish National Breast Cancer Registry Program (TNBCRP) which includes no organized population-based screening. Costs were estimated using direct data from the BMSP project and the reimbursement rates of Turkish Social Security Administration. The life-years saved by BMSP were estimated using the stage distribution observed with BMSP and TNBCRP. A total of 67 women (out of 7234 screened women) were diagnosed with breast cancer in BMSP. The stage distribution for AJCC stages O, I, II, III, IV was 19.4%, 50.8%, 20.9%, 7.5%, 1.5% and 4.9%, 26.6%, 44.9%, 20.8%, 2.8% with BMSP and TNBCRP, respectively. The BMSP program is expected to save 279.46 life years over TNBCRP with an additional cost of $677.171, which implies an incremental cost-effectiveness ratio (ICER) of $2.423 per saved life year. Since the ICER is smaller than the Gross Demostic Product (GDP) per capita in Turkey ($10.515 in 2014), BMSP program is highly cost-effective and remains cost-effective in the sensitivity analysis. Mammography screening may change the stage distribution of breast cancer in Turkey. Furthermore, an organized population-based screening program may be cost-effective in Turkey and in other developing countries. More research is needed to better estimate life-years saved with screening and further validate the findings of our study.

Vasectomy project launched in Turkey. Turkey's first VSC clinic.

One third of young married couples are currently using modern methods of contraception. Recent studies indicate that more than 30% of Turkey's married couples use withdrawal as their means of fertility control and only slightly more than 1% of Turkish families have opted for female sterilization. There is certainly an higher proportion of reproductive age married couples in Turkey which have completed their family size and could enjoy the advantages of permanent contraceptive methods. There has been little effort, however, on the part of the Turkish government to provide men with information and education on male voluntary surgical contraception (VSC), and the appropriate counseling and surgical services. As in many Asian, Islamic societies, the idea of males learning about and practicing family planning has long been culturally unacceptable. The Human Resource Development Foundation, with the assistance of Pathfinder International, opened the first VSC clinic for men in May 1989 in Ankara. This initiative makes Pathfinder the first private voluntary organization to establish a project offering VSC methods to Turkey's male population through hospital clinics. The urology department of the Ankara Social Security Hospital serves as the site for the project's counseling and training network. From that department, the project director and supervisor coordinate the development and establishment of male family planning clinics in surrounding hospitals. In just over two years, 19 urologists have been trained in VSC procedures and counseling, and more than 700 men have had vasectomies using the no-scalpel technique. An additional 6000 clients, both men and women, have received counseling on VSC procedures and the project's popularity continues to grow. The project expanded in 1991 into Istanbul and Izmir in response to growing demand for services. It is possible that even more expansion of VSC services is on the horizon in Turkey.

The prevalence of clarithromycin resistance has increased to the 20% or more in different regions of the world. Clarithromycin resistance is known to be responsible for most of the treatment failures in Helicobacter pylori (H. pylori) infection. The aim of this systematic review was to summarize the prevalence of primary antibiotic resistance (amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline) of H. pylori strains in different geographical regions of Turkey. An Internet search was performed using PubMed and the ULAKBIM Turkish Medical Database. The terms "primary antibiotic resistance (separately; amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline) of H. pylori" with and without "Turkey" or "different geographical regions of Turkey" were searched among articles published in both English and Turkish language within the time span from 1999 to 2015. Data analysis was performed using MedCalc 12.7.0. Each article was weighted according to the number of isolated H. pylori strains. Pooled proportion analysis was performed. Twenty-one Turkish studies including 1059 H. pylori strains were included in this review. The overall primary antibiotic resistance rates of H. pylori strains isolated in Turkey were as follows: amoxicillin 3 (0.971%), clarithromycin 425 (24.864%), metronidazole 75 (33.747%), tetracycline 2 (3.511%), and levofloxacin 31 (23.769%). Primary antibiotic resistance against H. pylori in Turkey shows differences between geographical regions and population densities. There is an increase in primary resistance rates to clarithromycin and metronidazole in different years. The data are not sufficient for tetracycline, amoxicillin, and levofloxacin. High clarithromycin resistance rates were mostly detected in overpopulated cities like Ankara (north), Izmir (west), Istanbul (west), and Bursa (west). © 2015 John Wiley & Sons Ltd.

The sea of Marmara is a region with the longest historical earthquake record of our planet. The earthquake of 10 July 1894 in Istanbul is the last earthquake of the historical period before the beginning of the instrumental period in the region. The magnitude and location of this earthquake and also its relationship with the North Anatolian Fault should be discussed in literature. Previous studies have not fully analyzed the historical data of 1894 earthquakes. For this reason, conflicting views are put forward regarding an earthquake in Marmara in the future. According to the historical records, the major damage was in the Istanbul Peninsula, Avcılar, Adalar, Karamürsel and Yalova. Due to its formation properties, it was effective in remote areas (İzmit, Gölcük, Adapazarı). It is clear that the most damage was in Old Istanbul and Prince Island. The tension cracks in different directions were observed in Heybeliada, Büyükada and Burgazada. There are observations to be interpreted as a tsunami wave about one and a half meter-height between Avcılar and Kartal. The submarine telegraph line extending from Kartal to Marmara Sea was broken at three points in the east of Büyükada. According to the damage assessment after the earthquake and other observations, it is understood that this earthquake was along the Adalar Fault. When considering seismic and multibeam data, it is apparent that the Adalar Fault was composed of echolon segments. The submarine landslides were mapped in front of the fault scarp. The Adalar Fault is a 45 km-long, 80o SW-dipping right-lateral normal oblique fault. The tsunami scenarios that we modelld along this fault are compatible with historical observations along the coast of İstanbul. Our GIS-based intensity scenario shows that the magnitude of the 1894 Istanbul Earthquake is Mw 7.

The Yarımburgaz cave which is located in the city of Istanbul, NW Turkey plays an important host to the first human culture and preserve significant archaeological and paleontological resources. The cave was formed as a result of a subterranean stream erosion on the limestones of the Eocene Kırklareli formation. It has been reported that a double cave with upper and lower entrance chambers exist, although no geophysical research was conducted to detect the cave's trunk passages and the extend of the sediment fill inside the cave. The aim of this study was to test the preferred order for detection the response to different geophysical methods applied on the cave. We therefore carried out an a series of geophysical study to determine the size, position, and depth of sinkholes inside the caves. Integrated methodological approaches including multichannel analysis of surface wave (MASW) 2- microtremor array method, 3-single station microtremor measurements, 4- electrical tomography (ET) measuruments and 5-microgravity imaging showed that the geophysical response was succesfully applied. Based upon the flow-chart we concluded that the microgravity survey should be applied as a first step to detect the air-filled void and the geometry of the cave. The electric tomography method was well applied showing high resistivity values across the voids. The surface wave method showed that the low-velocity zones are detected in various locations of the cave. In addition we the results of MASW and ReMi methods showed clearly the density variation in the lateral direction. Fundamental frequency value above void decraese according the properties of geological units in lateral directional, especially when they are engineering rock like limestone.

The Ottoman Empire maintained close relations with the neighbouring Italian city states in the 16th and 17th century. Yacub Pasha (1425-1481), personal physician of Mehmed II the Conqueror, was an Italian Jew who advanced to the title of pasha and vizier. Domenico Hierosolimitano (ca. 1552-1622), the third physician to Sultan Murad III, was a Jerusalemite rabbi. His book is an important source about everyday life and medical practice in Istanbul at the time. Nuh bin Abd al-Mennab (1627-1707), also of Italian stock, was the Chief Physician of the Ottoman Empire, who translated a pharmacopoeia into Turkish. In the same century, two Italians, Israel Conegliano (Conian) and Tobia Cohen became private physicians to leading Ottoman pashas and the Grand Vizier. A. Vuccino (1829-1893) and Antoine Calleja Pasha (1806-1893) taught at the Istanbul Medical School. Italy was a favoured country for medical education during the early period of Ottoman westernisation. Sanizade Mehmet Ataullah Efendi (1771-1826) translated the first medical book printed in the Ottoman Empire from Italian into Turkish. Mustafa Behcet Efendi (1774-1833), chief physician to the Sultan and the founder of the first western medical school in Turkey, translated several medical books from Italian into Turkish. The first printed pharmacopeia in the Ottoman Empire was also originally Italian In the 19th century, Edouard Ottoni and his son Giuseppe Ottoni were well-known military pharmacists, both under the name of Faik Pasha. Probably the most influential physician of Italian origin was Giovanni Battista Violi (1849-1928), who had practiced paediatrics in Turkey for more than fifty years. Violi was the founder of the first children's hospital, the first vaccine institute, and the first paediatric journal in the Ottoman Empire.

This study investigated the impact of working for public versus private ambulance services in Turkey and elaborated on predictors of mental, physical, and emotional well-being in emergency medical technicians (EMT-Bs). In this observational cross-sectional study, an 81-question self-report survey was used to gather data about employee demographics, socioeconomic status, educational background, working conditions, and occupational health and workplace safety (OHS), followed by the 12-item General Health Questionnaire (GHQ-12), the Work-Related Strain Inventory (WRSI), and the Maslach Burnout Inventory (MBI) with three subscales: Emotional Exhaustion (MBI-EE), Depersonalization (MBI-DP), and Diminished Personal Accomplishment (MBI-PA). In 2011, 1,038 EMT-Bs worked for publicly operated and 483 EMT-Bs worked for privately owned ambulance services in Istanbul, Turkey, of which 606 (58.4%) and 236 (48.9%) participated in the study (overall participation rate = 55.4%), respectively. On all scales, differences between total mean scores in both sectors were statistically insignificant (p > .05). In the public sector, work locations, false accusations, occupational injuries and diseases, work-related permanent disabilities, and organizational support were found to significantly influence self-reported perceptions of well-being (p < .05). In the private sector, commute time to and from work (p < .05), false accusations (p < .05), vocational training and education (p < .05), informed career choices (p < .05), and work-related permanent disabilities (p < .05) were found to significantly influence self-reported perceptions of well-being. EMT-Bs were asked about aspects of their working lives that need improvement; priority expectations in the public and private sectors were higher earnings (17.5%; 16.7%) and better social opportunities (17.4%; 16.8%). Working conditions, vocational training, and OHS emerged as topics that merit priority attention. © 2016 The Author(s).

In this study, near-surface geophysical techniques are used to investigate the physical characteristics of the Buyukcekmece landslide (Istanbul, Turkey). The Buyukcekmece landslide has continuous activity at a low velocity and is classified as a complex mechanism. It includes rototranslational parts, several secondary scarps, several landslide terraces, and evidence of two earth flows. It mainly develops in the clayey layers of the Danismen Formation. According to our findings, P-wave velocities ranging from 300 m/s to 2400 m/s do not provide notable discrimination between sliding mass and stable soil. They show variations in blocks reflecting a complex structure. We obtained the S-wave velocity structure of the landslide up to 80 m by combining the analysis of MASW and ReMi. It is clear that S-wave velocities are lower in the landslide compared to those of the stable area. Identical S-wave velocities for the entire area at depths higher than 60 m may point out the maximum thickness of the landslide mass. Resonance frequencies obtained from the H/V analysis of the landslide area are generally higher than those of the stable area. The depths computed by using an empirical relationship between the resonance frequency and the soil thickness point out the failure surfaces from 10 to 50 m moving downslope from the landslide crown area. The resistivity values within the landslide are generally lower than 30 Ω m, i.e., a typical value for remolded clayey debris. The geophysical results reflect an overview of the geological model, but the complexity of the landslide makes it difficult to map the landslide structure in detail.

The authors sought to estimate the impact of the open-air mass-casualty terrorist bombings of the Neve Shalom and Beth Israel Synagogues in Istanbul, Turkey, on November 15, 2003, on the American Hospital (AH) in terms of resource utilization, epidemiologic outcomes, and time course of emergency needs. A retrospective descriptive study using data from hospital records of injured survivors who used the emergency department at AH on November 15, 2003, to determine the number and percentage of injured survivors who were hospitalized, received operative care, had specific injury types, had an Injury Severity Score >/=16, died, and arrived within certain time intervals. AH received 69 (91%) injured survivors from the scene, of which nine (12%) were hospitalized and three (4%) received operative care. Starting four hours after the initial blast, seven (9%) injured survivors were transferred to AH from other hospitals, of which five (7%) were hospitalized and four (5%) received operative care. Of the 49 injured survivors from the scene with documented injuries, 43 (88%) had injuries to the head or face, 42 (86%) had lacerations, five (10%) had fractures, one (2%) had a penetrating eye injury, one (2%) had a serious intracranial injury, and none had primary blast injuries. Four (5%) injured survivors at AH had an Injury Severity Score >/=16, and none died. Seventy-six injured survivors used the emergency department at AH, including a delayed wave of injured survivors transferred from other hospitals. The majority of injured survivors with documented injuries had non-life-threatening lacerations of the head or face, and relatively few injured survivors were hospitalized or received operative care.

Water vapor is a key component for modelling atmosphere and climate studies. Moreover, long-term water vapor changes can be an independent source for detecting climate changes. Since Global Navigation Satellite Systems (GNSS) use microwaves passing through the atmosphere, atmospheric effects are modeled with high accuracy. Tropospheric effects on GNSS signals are estimated with total zenith delay parameter (ZTD) which is the sum of hydrostatic (ZHD) and wet zenith delay (ZWD). The first component can be obtained from meteorological observations with high accuracy; the second component, however, can be computed by subtracting ZHD from ZTD (ZWD=ZTD-ZHD). Afterwards, the weighted mean temperature (Tm) or the conversion factor (Q) is used for the conversion between the precipitable water vapor (PWV) and ZWD. The parameters Tm and Q are derived from the analysis of radiosonde stations' profile observations. Numerous Q and Tm models have been developed for each radiosonde station, radiosonde station group, countries and global fields such as Bevis Tm model and Emardson and Derks' Q models. So, PWV models (Tm and Q models) applied for Turkey have been developed using a year of radiosonde data (2011) from 8 radiosonde stations. In this study the models developed are tested by comparing PWVGNSS computed applying Tm and Q models to the ZTD estimates derived by Bernese and GAMIT/GLOBK software at GNSS stations established at Istanbul and Ankara with those from the collocated radiosonde stations (PWVRS) from October 2013 to December 2014 with the data obtained from a project (no 112Y350) supported by the Scientific and Technological Research Council of Turkey (TUBITAK). The comparison results show that PWVGNSS and PWVRS are in high correlation (86 % for Ankara and 90% for Istanbul). Thus, the most applicable model for Turkey and the accuracy of GNSS meteorology are investigated. In addition, Tm model was applied to the ZTD estimates of 20 TUSAGA-Active (CORS-TR) stations in the 38.0°-42.0° northern latitudes and 28.0°-34.0° eastern longitudes of Turkey and PWV were computed. ZTD estimates of these stations were computed using Bernese GNSS Software v5.0 during the period from June 2013 to June 2014. Preceding the PWV estimation, meteorological parameters for these stations (temperature, pressure and humidity) are derived by applying spherical harmonics modelling and interpolation to the above-mentioned meteorological parameters measured by meteorological stations surrounding TUSAGA-Active stations. Results of spherical harmonics modelling and interpolation yield the precision of ±1.74 K in temperature, ±0.95 hPa in pressure and ±14.88 % in humidity. Also, the PWV of TUSAGA-Active stations selected were estimated.

There have been many destructive earthquakes and tsunamis in the world.The recent events are, 2011 East Japan Earthquake/Tsunami in Japan, 2015 Nepal Earthquake and 2016 Kumamoto Earthquake in Japan, and so on. And very recently a destructive earthquake occurred in Central Italy. In Turkey, the 1999 Izmit Earthquake as the destructive earthquake occurred along the North Anatolian Fault (NAF). The NAF crosses the Sea of Marmara and the only "seismic gap" remains beneath the Sea of Marmara. Istanbul with high population similar to Tokyo in Japan, is located around the Sea of Marmara where fatal damages expected to be generated as compound damages including Tsunami and liquefaction, when the next destructive Marmara Earthquake occurs. The seismic risk of Istanbul seems to be under the similar risk condition as Tokyo in case of Nankai Trough earthquake and metropolitan earthquake. It was considered that Japanese and Turkish researchers can share their own experiences during past damaging earthquakes and can prepare for the future large earthquakes in cooperation with each other. Therefore, in 2013 the two countries, Japan and Turkey made an agreement to start a multidisciplinary research project, MarDiM SATREPS. The Project runs researches to aim to raise the preparedness for possible large-scale earthquake and Tsunami disasters in Marmara Region and it has four research groups with the following goals. 1) The first one is Marmara Earthquake Source region observational research group. This group has 4 sub-groups such as Seismicity, Geodesy, Electromagnetics and Trench analyses. Preliminary results such as seismicity and crustal deformation on the sea floor in Sea of Marmara have already achieved. 2) The second group focuses on scenario researches of earthquake occurrence along the North Anatolia Fault and precise tsunami simulation in the Marmara region. Research results from this group are to be the model of earthquake occurrence scenario in Sea of Marmara and the case studies with advanced tsunami simulation for measure cities. 3) Aims of the third group are improvements and constructions of seismic characterizations and damage predictions based on observation researches and precise simulations. Research results from this group will be very important for disaster measures. 4) The fourth group is promoting disaster educations using research result visuals. The mission of this group is very important for information dissemination and practical and effective disaster education in Turkey. The research results from all components will be integrated and utilized for disaster mitigation in Marmara region and disaster education in Turkey. Updated research results of the MarDiM SATREPS Project will be officially presented toward the end of the Project period, which is March 2018.

Adolescent substance use is an increasing major health problem in developing countries. To evaluate the sociodemographic characteristics and drug abuse patterns of children and youth seeking treatment in Turkey. This retrospective study reviewed the demographic and clinical data of substance users who visited the substance addiction treatment clinic for children and youth in Bakırköy Research and Training Hospital for Psychiatry, Neurology and Neurosurgery in Istanbul, between January 2011 and December 2012. The sample comprised of 1969 children and youth aged between 11 and 20 (346 female and 1623 male). Cannabis (60.1%), followed by solvents/inhalants (38.3%) and ecstasy (33.4%), were the most prevalent substances used. The use of solvents/inhalants was more common among males, whereas ecstasy and cocaine use were more common among females. The mean age for the onset of substance use was 13 years. The proportion of polysubstance use was 60.2%. There was a mean duration of 2.28 ± 1.91 years between the first substance use and seeking treatment. The risk factors for most of the drug usage were onset of substance use at a young age, gender, treatment admission at older ages, higher parental criminal history, and having substance using parents or relatives. Findings of the very early onset of substance and polysubstance use indicated easy accessibility of legal and illicit substances by children and youth in Istanbul. These findings on Turkish children and youth who seek substance use treatment can be useful in developing preventive early interventions and treatment facilities.

We investigated the knowledge and attitudes of community pharmacists towards pharmacovigilance and adverse drug reactions (ADRs) in Kadiköy district of Istanbul (Turkey). The community pharmacies in Kadikoy. Kadikoy is one of the biggest districts of Istanbul and has the largest number of pharmacies. Kadikoy district was divided into two regions, the central and the peripheral. Between December 2005 and June 2006 we conducted a survey about the knowledge and attitude of community pharmacists (n = 219) using a face-to-face questionnaire. The questionnaire consisted of questions about the sociodemographic characteristics of the pharmacists, their knowledge of pharmacovigilance and their attitudes towards ADR reporting. The knowledge of pharmacovigilance practice, ADR reporting compliance rates, reasons for not reporting ADR and perceptions of the Turkish community pharmacists on pharmacovigilance practice were evaluated. Although all 411 pharmacies in the Kadikoy district were visited, only 53% of the community pharmacists (n = 219) consented to participate in the study. Of those that did respond, only 17.2% of the pharmacists had any knowledge about 'pharmacovigilance'. Sixty-five percent of the pharmacists stated that patients reported an ADR to them during the previous 12 months, and 21% of pharmacists reported to the concerned organizations. Our survey showed that only 7% actually reported an ADR to the national pharmacovigilance center. On the other hand, 89% of the pharmacists believed that the role of the pharmacist in ADR reporting was essential. The results show that Turkish community pharmacists have poor knowledge about pharmacovigilance. There is an urgent need for educational programs to train them about pharmacovigilance and ADR reporting.

The presence of antibodies to feline coronavirus (FCoV) and feline immunodeficiency virus (FIV), together with feline leukemia virus (FeLV) antigen was investigated in 169 ill household and stray cats attending a veterinary surgery in Istanbul in 2009-14. The estimated FCoV and FIV seroprevalence (95% confidence intervals) were 37% (30-45%) and 11% (6-16%), respectively and FeLV prevalence was 1% (0-3%). FCoV seroprevalence increased until 2 years of age, was highest in 2014 and among household cats living with other cats and with outdoor access, and was lower in FIV seropositive compared to seronegative cats. Symptoms typically associated with wet feline infectious peritonitis (FIP) including ascites, abdominal distention or pleural effusion, coupled in many cases with non-antibiotic responsive fever, were observed in 19% (32/169) of cats, and 75% (24/32) of these cats were FCoV seropositive. FCoV seropositivity was also associated with a high white blood cell count, high plasma globulin, low plasma albumin and low blood urea nitrogen. The percentage of FCoV seropositive and seronegative cats that died in spite of supportive veterinary treatment was 33% (21/63) and 12% (13/106), respectively. These results indicate that FCoV is widespread and has a severe clinical impact in cats from Istanbul. Moreover, the incidence of FCoV infections could be rising, and in the absence of effective vaccination cat owners need to be made aware of ways to minimize the spread of this virus.

Aim of this study was to determine the prevalence and correlates of energy-drink (ED) consumption among 10th grade students in Istanbul/Turkey. Cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire included sections about demographic data, self-destructive behavior and use of substances including tobacco, alcohol and drugs. Also Psychological Screening Test for Adolescents (PSTA) was used. The analyses were conducted based on the 4957 subjects. Rate of those reported a ED consumption once within last year was 62.0% (n=3072), whereas rate of those reported ED consumption at least once in a month was 31.1%. There were consistent, statistically significant associations between genders, lifetime substance use (tobacco, alcohol and drug use), measures of sensation seeking, psychological problems (depression, anxiety, anger, impulsivity) and self-destructive behavior (self-harming behavior and suicidal thoughts) with ED consumption. In logistic regression models male gender, sensation seeking, life-time tobacco, alcohol and drug use predicted all frequencies of ED consumption. In addition to these predictors, anger and self-harming behavior also predicted ED consumption at least once in a month. There were no interactions between the associations of lifetime tobacco, alcohol and drug use with ED consumption. The findings suggest that the ED consumption of male students is related with three clusters of substances (tobacco, alcohol and drug) through sensation seeking and these relationships do not interact with each other.

We aimed to determine the molecular characteristics and genetic diversity between European clones I, II, and III from Turkey and Azerbaijan. In this study, a total of 112 bloodstream isolates of carbapenem-resistant Acinetobacter spp. were collected from 11 hospitals across Turkey and Azerbaijan. The identification of Acinetobacter spp. using conventional and sensitivity tests was performed by standard criteria. Multiplex polymerase chain reaction (PCR) was used to detect OXA carbapenemase-encoding genes (bla OXA-23-like, bla OXA-24-like, bla OXA-51-like, and bla OXA-58-like). Pulsed-field gel electrophoresis (PFGE) typing was used to investigate genetic diversity. The bla OXA-51-like gene was present in all 112 isolates, 75 (67 %) carried bla OXA-23-like, 7 (6.2 %) carried bla OXA-58-like genes, and 5 (4.5 %) carried bla OXA-24-like genes. With a 90 % similarity cut-off value, 15 clones and eight unique isolates were identified. The largest clone was cluster D, with six subtypes. Isolates from clusters D and I were widely spread in seven different geographical regions throughout Turkey. However, F cluster was found in the northern and eastern regions of Turkey. EU clone I was grouped within J cluster with three isolates found in Antalya, Istanbul, and Erzurum. EU clone II was grouped in the U cluster with 15 isolates and found in Kayseri and Diyarbakır. The bla OXA-24-like gene in carbapenemases was identified rarely in Turkey and has been reported for the first time from Azerbaijan. Furthermore, this is the first multicenter study in Turkey and Azerbaijan to identify several major clusters belonging to European clones I and II of A. baumannii.

Seismotectonic methods allowing quantitative measures of the frequency and severity of earthquakes have greatly advanced over the last 30 years, aided by high-resolution imagery, digital topography and modern techniques for dating. During the same period, deterministic models based on the physics of earthquakes (Coulomb stress interactions) have been extensively developed to explain the distribution of earthquakes in space and time. Seismotectonic data and Coulomb Stress models provide valuable information on seismic hazard and could assist the public policy, disaster risk management and financial risk transfer communities to make more informed decisions around their strategic planning and risk management activities. The Sea of Marmara and Istanbul regions (North Anatolian Fault, NAF) are among the most appropriate on Earth to analyse seismic hazard, because reliable data covers almost completely two seismic cycles (the past ~500 years). Earthquake ruptures associated with historical events have been found in the direct vicinity of the city, on the Marmara sea floor. The MARMARASCARPS cruise using an unmanned submersible (ROV) provides direct observations to study the morphology and geology of those ruptures, their distribution and geometry. These observations are crucial to quantify the magnitude of past earthquakes along the submarine fault system (e.g. 1894, 1912, 1999, M > 7). In particular, the identification of a break continuous over 60 km with a right-lateral slip of 5 m, corresponding probably to the offshore extension of the Ganos earthquake rupture (1912, Ms 7.4), modifies substantially our understanding of the current state of loading along the NAF next to Istanbul. Coulomb stress analysis is used to characterise loading evolution in well-identified fault segments, including secular loading from below and lateral loading imposed by the occurrence of previous earthquakes. The 20th century earthquake sequence in the region of Istanbul is modelled using geological and geophysical records. For the 18th century M≥7.0 earthquake clusters, we construct scenarios consistent with the tectonic and historical data. Coulomb stress modeling including the 20th and 18th century historical events shows a current zone of maximum loading along a 70 km long strike-slip segment, south-west of Istanbul, with at least 4-5 m of slip deficit. That segment alone would be capable of generating a large magnitude earthquake (Mw 7.2). Other segments in Marmara appear less loaded.

Objectives The aim of the study was to investigate feline morbillivirus (FmoPV) frequency, phylogeny and associated pathology in cats in Istanbul, Turkey. Methods Samples from sick (n = 96) and dead ( n = 15) cats were analysed using reverse transcription PCR. Blood and urine analyses and histopathology were also performed. Results FmoPV RNA was detected in six cats (5.4%), including three sick (in the urine) and three dead cats (tissues). A significantly greater proportion of FmoPV RNA-positive cats had street access compared with non-infected cats. Blood samples from the morbillivirus-positive cats were negative for morbillivirus RNA. Tubular parenchymal cells, lymphoid and plasma cells in kidney and hepatocytes, lymphoid and plasma cells in liver from dead cats were also positive by immunohistochemistry for the viral N protein. Two FmoPV-positive cats were also positive for feline coronavirus RNA and one cat for feline immunodeficiency virus RNA and feline leukaemia virus proviral DNA. Phylogenetic analysis of the six FmoPV-positive cats showed that the strains were grouped into cluster D and had high similarity (98.5-100%) with strains from Japan and Germany. In the three FmoPV RNA-positive sick cats, respiratory, urinary and digestive system signs were observed as well as weight loss, fever and depression in some cats. Similar clinical signs were also seen in the morbillivirus RNA-negative sick cats. FmoPV RNA-positive cats had lower median red blood cell count, haemoglobin, albumin, albumin/globulin and urobilinogen and higher alanine transaminase, alkaline phosphatase and bilirubin compared with non-infected cats. Significant histopathology of FmoPV RNA-positive dead cats included tubulointerstitial nephritis characterised by severe granular and vacuolar degeneration of the epithelial cells of the cortical and medullary tubules as well as mononuclear cell infiltrates. Widespread lymphoid cell infiltrates were detected in the renal cortex and medullary regions of the kidneys. Cellular infiltration, cholangiohepatitis and focal necrosis in the liver were also found. Although virus-infected cells were found in the kidney and liver of FmoRV RNA-positive cats, tubulointerstitial nephritis, cholangiohepatitis and focal necrosis seen in FmoRV RNA-positive cats were similar to those observed in FmoRV RNA-negative cats. Conclusions and relevance This is the first study to show the presence of FmoPV infection in cats in Turkey. Sick cats, particularly those with kidney disease, should be tested for this virus. The genotypes found in this study were similar to previously reported strains, indicating that circulating morbilliviruses in Turkey are conserved.

Objectives: To determine the relation among the risk of falls, geriatric assessment, and anthropometric measurements, including the mini mental state examination, geriatric depression scale, handgrip test, and key pinch test. Methods: This prospective study included 89 residents hospitalized between May 2014 and September 2015 in the geriatric care unit of the Istanbul Balikli Rum Hospital, Istanbul, Turkey. Patients were followed-up for one year, and their falls were recorded. Medical records of the included patients were retrieved and analyzed. Results: A total of 89 patients, comprising 37 men and 52 women with an average age of 75.8 ± 8.2 years were included in the study. The residents’ annual falling averages were 1.0 ± 1.5. The most significant factors were identified to be predicted muscle mass, skeletal muscle index, whole body bioimpedance, dominant arm muscle strength, dominant arm bioimpedance, and free fat mass. Conclusions: The mini mental test, geriatric depression scale and lawton-brody scale combined with the handgrip, 6-meters walking, and bioimpedance tests are favorable for detecting the risk of falls and recurrent falls in vulnerable elderly nursing home residents.

To determine the feasibility, advantages, and disadvantages of using a robot for holding and maneuvering the endoscope in transnasal transsphenoidal surgery. The system used in this study was a Stewart Platform based robotic system that was developed by Kocaeli University Department of Mechatronics Engineering for positioning and holding of endoscope. After the first use on an artificial head model, the system was used on six fresh postmortem bodies that were provided by the Morgue Specialization Department of the Forensic Medicine Institute (Istanbul, Turkey). The setup required for robotic system was easy, the time for registration procedure and setup of the robot takes 15 minutes. The resistance was felt on haptic arm in case of contact or friction with adjacent tissues. The adaptation process was shorter with the mouse to manipulate the endoscope. The endoscopic transsphenoidal approach was achieved with the robotic system. The endoscope was guided to the sphenoid ostium with the help of the robotic arm. This robotic system can be used in endoscopic transsphenoidal surgery as an endoscope positioner and holder. The robot is able to change the position easily with the help of an assistant and prevents tremor, and provides a better field of vision for work.

This descriptive study was conducted to determine the validity and reliability in Turkey of the Pediatric Quality of Life Inventory Cancer Module (PedsQL 3.0) for children aged 8-12 in the hematology-oncology polyclinics of two university hospitals in Istanbul during the period 2006-2007. The data collection instruments were the Pediatric Quality of Life Inventory (PedsQL 4.0), the Pediatric Quality of Life Inventory Cancer Module (PedsQL 3.0) and a socio-demographic questionnaire, applied for 146 children diagnosed with cancer and 146 parents. Cronbach's alpha coefficients for the PedsQL 3.0 were found to be 0.602-0.982 for sub-groups with the children's form, 0.644-0.966 with the parents' form. The scale was found to give a significantly high level of reliability (0.60 ≤ ± < 0.80). Significant and directly proportional correlations were demonstrated between the forms for children and parents. It was concluded that the PedsQL 3.0 cancer module is a valid and reliable tool for assessing the quality of life of Turkish children, aged 8-12, diagnosed with cancer.

There is insufficient empirical evidence on the correlates of health care utilization of irregular migrants currently living in Turkey. The aim of this study was to identify individual level determinants associated with health service and medication use. One hundred and fifty-five Afghans completed surveys assessing service utilization including encounters with primary care physicians and outpatient specialists in addition to the use of prescription and nonprescription medicines. Multivariate logistic regression analyses were employed to examine associations between service use and a range of predisposing, enabling, and perceived need factors. Health services utilization was lowest for outpatient specialists (20%) and highest for nonprescription medications (37%). Female gender and higher income predicted encounters with primary care physicians. Income, and other enabling factors such as family presence in Turkey predicted encounters with outpatient specialists. Perceived illness-related need factors had little to no influence on use of services; however, asylum difficulties increased the likelihood for encounters with primary care physicians, outpatient services, and the use of prescription medications. This study suggests that health services use among Afghan migrants in Turkey is low considering the extent of their perceived illness-related needs, which may be further exacerbated by the precarious conditions in which they live.

A century-long sedimentary record of pesticide use in the Küçükçekmece Lagoon region, Turkey

NASA Astrophysics Data System (ADS)

Organochlorine pesticides (OCPs), extensively used for pest and disease control since the 1940s, can be bioaccumulated through food chains and cause adverse impacts on the environment and human health. Their use and manufacture have been banned or restricted in the 1980s in most countries. OCPs have a strong affinity to suspended particles, so they subsequently settle down into sediment. Sediments in aquatic systems could also become another source of OCPs, due to water turbulence, dredging and bioturbation. Piston coring recoveries in the Küçükçekmece Lagoon, a coastal wetland protected from the sea by a narrow strip of sandbar in the western part of Istanbul, indicated mostly homogeneous and seasonally layered lithological textures throughout the cores. The sediment profiles seem to be not subjected serious physical rearrangements, so that there is the opportunity for deposit preservation. The core 5 was analysed to delineate the vertical variations of selected organochlorine pesticide (OCPs) residues using gas chromatography (GC-ECD/MS) and dated using 210Pb and 137Cs dating methods. The total OCP residues ranged from 3.0 to 498.7 ng/g-dw, with the median concentration of 64 ng/g-dw, while α-HCH and p,p'-DDT were dominant OCPs, with maximum concentrations of 469.3 and 71.0 ng/g dw, respectively. Dated concentration-depth profiles suggest that highest inputs occurred in the first half of last century and followed by significant decreases. Despite the restriction in use, the prevalent nature of OCPs in the core sediment reflects the persistent nature and the lipophilic character of these contaminants. The major sources of the HCHs were from the use of technical HCHs. Sources DDTs identified by specific molecular ratios indicated that DDT residues were mainly originated from technical DDTs from both historical usage and recent input. The organochlorine pesticide residues did demonstrate markedly different distributions reflecting different agricultural and domestic usage in the region. Even though the risk of sediment toxicity was not so high according to the sediment quality guidelines, the bioaccumulation and the amplification of toxic organic pollutants may have major implications. Therefore, this study on the residual levels of the OCPs, their temporal distributions and the source analysis will not only contribute to understanding the environmental behaviour but also provide the necessary theoretical basis for persistent toxic pollution prevention and lake environmental management. This research was supported by the Scientific and Technological Council of Turkey (112Y104) and the Research Funds of Istanbul University (byp-22247).

Shaded Relief and Radar Image with Color as Height, Bosporus Strait and Istanbul, Turkey

NASA Technical Reports Server (NTRS)

2002-01-01

The Bosporus (also spelled Bosphorus) is a strait that connects the Black Sea with the Sea of Marmara in the center of this view of northwest Turkey, taken during the Shuttle Radar Topography Mission. The water of the Black Sea at the top of the image and Sea of Marmara below the center are colored blue in this image, along with several large lakes. The largest lake, to the lower right of the Sea of Marmara, is Iznik Lake. The Bosporus (Turkish Bogazici) Strait is considered to be the boundary between Europe and Asia, and the large city of Istanbul, Turkey is located on both sides of the southern end of the strait, visible as a brighter (light green to white) area on the image due to its stronger reflection of radar. Istanbul is the modern name for a city with along history, previously called Constantinople and Byzantium. It was rebuilt as the capital of the Roman Empire in 330 A.D. by Constantine on the site of an earlier Greek city, and it was later the capital of the Byzantine and Ottoman empires until 1922.

The Gulf of Izmit is the narrow gulf extending to the east (right) from the Sea of Marmara. The city of Izmit at the end of the gulf was heavily damaged by a large magnitude 7.4 earthquake on August 17,1999, often called the Izmit earthquake (also known as the Kocaeli, Turkey, earthquake), that killed at least 17,000 people. A previous earthquake under the Gulf of Izmit in 1754 killed at least 2,000people. The Izmit earthquake ruptured a long section of the North Anatolian Fault system from off the right side of this image continuing under the Gulf of Izmit. Another strand of the North Anatolian Fault system is visible as a sharp linear feature in the topography south of Iznik Lake. Bathymetric surveys show that the north Anatolian Fault system extends beneath and has formed the Sea of Marmara, in addition to the Gulf of Izmit and Iznik Lake. Scientists are studying the North Anatolian Fault system to determine the risk of a large earthquake on the faults close to Istanbul that could kill many more than the 1999 event.

Three visualization methods were combined to produce this image: shading and color coding of topographic height and radar image intensity. The shade image was derived by computing topographic slope in the northwest-southeast direction. Northwest-facing slopes appear dark and southeast-facing slopes appear bright. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and brown to white at the highest elevations. The shade image was combined with the radar intensity image to add detail, especially in the flat areas.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C.

Key words: Ground Penetrating Radar (GPR), Magnetometry, Geophysical Data Integration, Principal Component Analyse (PCA), Aizanoi Archaeological Site An application of geophysical integration methods which often appealed are divided into two classes as qualitative and quantitative approaches. This work focused on the application of quantitative integration approaches, which involve the mathematical and statistical integration techniques, on the archaeo-geophysical data obtained in Aizanoi Archaeological Site,Turkey. Two geophysical methods were applied as Ground Penetrating Radar (GPR) and Magnetometry for archaeological prospection on the selected archaeological site. After basic data processing of each geophysical method, the mathematical approaches of Sums and Products and the statistical approach of Principal Component Analysis (PCA) have been applied for the integration. These integration approches were first tested on synthetic digital images before application to field data. Then the same approaches were applied to 2D magnetic maps and 2D GPR time slices which were obtained on the same unit grids in the archaeological site. Initially, the geophysical data were examined individually by referencing with archeological maps and informations obtained from archaeologists and some important structures as possible walls, roads and relics were determined. The results of all integration approaches provided very important and different details about the anomalies related to archaeological features. By using all those applications, integrated images can provide complementary informations as well about the archaeological relics under the ground.

Turkey is located on one of the world's most hazardous earthquake zones. The northern branch of the North Anatolian fault beneath the Sea of Marmara, where the population is most concentrated, is the most active fault branch at least since late Pliocene. The Sea of Marmara region has been affected by many large tsunamigenic earthquakes; the most destructive ones are 549, 553, 557, 740, 989, 1332, 1343, 1509, 1766, 1894, 1912 and 1999 events. In order to understand and determine the tsunami potential and their possible effects along the coasts of this inland sea, detailed documentary, geophysical and numerical modelling studies are needed on the past earthquakes and their associated tsunamis whose effects are presently unknown.On the northern coast of the Sea of Marmara region, the Kucukcekmece Lagoon has a high potential to trap and preserve tsunami deposits. Within the scope of this study, lithological content, composition and sources of organic matters in the lagoon's bottom sediments were studied along a 4.63 m-long piston core recovered from the SE margin of the lagoon. The sedimentary composition and possible sources of the organic matters along the core were analysed and their results were correlated with the historical events on the basis of dating results. Finally, a tsunami scenario was tested for May 22nd 1766 Marmara Sea Earthquake by using a widely used tsunami simulation model called NAMIDANCE. The results show that the candidate tsunami deposits at the depths of 180-200 cm below the lagoons bottom were related with the 1766 (May) earthquake. This work was supported by the Scientific Research Projects Coordination Unit of Istanbul University (Project 6384) and by the EU project TRANSFER for coring.

Intuitive Eating is defined as "the dynamic process-integrating attunement of mind, body, and food". The purpose of this study was, therefore, adapt the IES-2 to the Turkish language and reliability and validity of IES-2 among Turkish populations. We also examined the instrument's internal consistency and test-retest reliability and analysed the relationships between the IES-2 and several variables so as to evaluate the convergent and discriminant validity. Three hundred seventy-seven undergraduate and postgraduate women and men between the ages of 19-31 years (mean 22.3, SD = 3.53) attending two large private universities in Istanbul, Turkey. The best solution from the principal factors analysis of the 23 items of the IES-2 revealed four factors corresponding to the four subscales (F1: Eating for physical rather than emotional reasons; F2: Unconditional permission to eat; F3: Reliance on hunger and satiety cues; F4: Body-food choice congruence), as reported by the authors of the questionnaire. Bartlett's test of sphericity gave X 2  = 9043.49 (p < 0.001), while the Kaiser-Meyer-Olkin index was 0.87 (KMO were 0.89 for women and 0.83 for men). The test-retest reliability of the IES-2 was 0.88 for the IES-2 total score. The IES-2 had a = 0.82. These findings support the notion that intuitive eating is a viable concept for university students and the IES can be used to examine adaptive eating behaviors in this population. Copyright © 2017.

Dense continuous GPS networks quantify the time-dependent deformation field of the earthquake cycle. However the strainmeters can capture signals with superior precision at local spatial scales, in particular in the short-period, from minutes to a month. Many relatively small-scale events (e.i. SSEs, creeps) have been successfully determined on the subduction zones. Istanbul located near the most active parts of the North Anatolian Fault (NAF) has been monitored by different observing techniques such as seismic networks and continuous/survey-mode GPS networks for decades. However, it is still essential to observe deformation in a broad range of temporal and spatial scales (from seismology to geodesy and to geology). Borehole strainmeters are very sensitive to deformation in the range of less than a month. In this study, we present a new project, financially and technically supported by Istanbul Development Agency (ISTKA) and UNAVCO, respectively, which includes the installation of two borehole strainmeters are being deployed in European side of Istanbul in Marmara Region. Since these instruments can also respond to non-tectonic processes, it is necessary to have more instruments to increase spatial coherence and to have additional sensors to detect and model noise (such as barometric pressure, tides, or precipitation). The introduced monitoring system will provide significant insight about the creeping phenomenon and the possible SSE to our understanding of seismic hazards in active zones and possible precursors. Our long term objective is to build a borehole monitoring system in the region. By integrating various data obtained from borehole observations, we expect to get a better understanding of dynamics in the western NAF. In this presentation, we introduce data and ongoing analysis obtained with strainmeters.

An Investigation on the Crustal Deformations in Istanbul after Eastern Marmara Earthquakes in 1999

Since the introduction of the GPS technique in mid 1970's there has been great advances in positioning activities. Today such Global Navigational Satellite Systems (GNSS) based positioning techniques are widely used in daily geodetic applications. High order geodetic network measurements are one of such geodetic applications. Such networks are established to provide reliable infrastructures for all kind of geodetic work from the production of cadastral plans to the surveying processes during the construction of engineering structures. In fact such positional information obtained in such engineering surveys could be useful for other studies as well. One of such fields is geodynamic studies where such positional information could be valuable to understand the characteristics of tectonic movements. In Turkey being located in a tectonically active zones and having major earthquakes quite frequently, the positional information obtained in engineering surveys could be very useful for earthquake related studies. In this paper an example of such engineering surveys is discussed. This example is the Istanbul GPS (Global Positioning System) Network, first established in 1997 and remeasured in 2005. Between these two measurement processes two major earthquakes took place, on August 17 and November 12, 1999 with magnitudes of 7.4 and 7.2, respectively. In the first measurement campaign in 1997, a network of about 700 points was measured, while in the second campaign in 2005 more than 1800 points were positioned. In these two campaigns are existing common points. The network covers the whole Istanbul area of about 6000 km2. All network points are located on the Eurasian plate to the north of the North Anatolian Fault Zone. In this study, the horizontal and vertical movements are presented and compared with the results obtained in geodynamic studies.

New earthquake probability calculations are made for the Sea of Marmara region and the city of Istanbul, providing a revised forecast and an evaluation of time-dependent interaction techniques. Calculations incorporate newly obtained bathymetric images of the North Anatolian fault beneath the Sea of Marmara [Le Pichon et al., 2001; Armijo et al., 2002]. Newly interpreted fault segmentation enables an improved regional A.D. 1500-2000 earthquake catalog and interevent model, which form the basis for time-dependent probability estimates. Calculations presented here also employ detailed models of coseismic and postseismic slip associated with the 17 August 1999 M = 7.4 Izmit earthquake to investigate effects of stress transfer on seismic hazard. Probability changes caused by the 1999 shock depend on Marmara Sea fault-stressing rates, which are calculated with a new finite element model. The combined 2004-2034 regional Poisson probability of M≥7 earthquakes is ~38%, the regional time-dependent probability is 44 ± 18%, and incorporation of stress transfer raises it to 53 ± 18%. The most important effect of adding time dependence and stress transfer to the calculations is an increase in the 30 year probability of a M ??? 7 earthquake affecting Istanbul. The 30 year Poisson probability at Istanbul is 21%, and the addition of time dependence and stress transfer raises it to 41 ± 14%. The ranges given on probability values are sensitivities of the calculations to input parameters determined by Monte Carlo analysis; 1000 calculations are made using parameters drawn at random from distributions. Sensitivities are large relative to mean probability values and enhancements caused by stress transfer, reflecting a poor understanding of large-earthquake aperiodicity.

We have simulated strong ground motions for two Mw>7.0 rupture scenarios on the North Anatolian Fault, in the Marmara Sea within 10-20 km from Istanbul. This city is characterized by one of the highest levels of seismic risk in Europe and the Mediterranean region. The increased risk in Istanbul is due to eight destructive earthquakes that ruptured the fault system and left a seismic gap at the western portion of the 1000km-long North Anatolian Fault Zone. To estimate the ground motion characteristics and its variability in the region we have simulated physics-based rupture scenarios, producing hybrid broadband time histories. We have merged two simulation techniques: a full 3D wave propagation method to generate low-frequency seismograms (Aochi and Ulrich, 2015) and the stochastic finite-fault model approach based on a dynamic corner frequency (Motazedian and Atkinson, 2005) to simulate high-frequency seismograms (Akinci et al., 2016, submitted to BSSA, 2016). They are merged to compute realistic broadband hybrid time histories. The comparison of ground motion intensity measures (PGA, PGV, SA) resulting from our simulations with those predicted by the recent Ground Motion Prediction Equations (GMPEs) in the region (Boore & Atkinson, 2008; Chiou & Young, 2008; Akkar & Bommer, 2010; Akkar & Cagnan, 2010) seems to indicate that rupture directivity and super-shear rupture effects affect the ground motion in the Marmara Sea region. In order to account for the rupture directivity we improve the comparison using the directivity predictor proposed by Spudich & Chiu (2008). This study highlights the importance of the rupture directivity for the hazard estimation in the Marmara Sea region, especially for the city of Istanbul.

Background In order to control and eliminate the vaccine preventable diseases it is important to know the vaccination coverage and reasons for non-vaccination. The primary objective of this study was to determine the complete vaccination rate; the reasons for non-vaccination and the predictors that influence vaccination of children. The other objective was to determine coverage of measles vaccination of the Measles Immunization Days (MID) 2005 for children aged 9 month to 6 years in a region of Umraniye, Istanbul, Turkey. Methods A '30 × 7' cluster sampling design was used as the sampling method. Thirty streets were selected at random from study area. Survey data were collected by a questionnaire which was applied face to face to parents of 221 children. A Chi-square test and logistic regression was used for the statistical analyses. Content analysis method was used to evaluate the open-ended questions. Results The complete vaccination rate for study population was 84.5% and 3.2% of all children were totally non-vaccinated. The siblings of non-vaccinated children were also non-vaccinated. Reasons for non-vaccination were as follows: being in the village and couldn't reach to health care services; having no knowledge about vaccination; the father of child didn't allow vaccination; intercurrent illness of child during vaccination time; missed opportunities like not to shave off a vial for only one child. In logistic regression analysis, paternal and maternal levels of education and immigration time of both parents to Istanbul were found to influence whether children were completely vaccinated or non-vaccinated. Measles vaccination coverage during MID was 79.3%. Conclusion Efforts to increase vaccination coverage should take reasons for non-vaccination into account. PMID:16677375

As a result of industrialization, throughout the world, cities have been growing rapidly for the last century. One typical example of these growing cities is Istanbul, the population of which is over 10 million. Due to rapid urbanization, new areas suitable for settlement and engineering structures are necessary. The Cekmece area located west of the Istanbul metropolitan area is studied, because the landslide activity is extensive in this area. The purpose of this study is to develop a model that can be used to characterize landslide susceptibility in map form using logistic regression analysis of an extensive landslide database. A database of landslide activity was constructed using both aerial-photography and field studies. About 19.2% of the selected study area is covered by deep-seated landslides. The landslides that occur in the area are primarily located in sandstones with interbedded permeable and impermeable layers such as claystone, siltstone and mudstone. About 31.95% of the total landslide area is located at this unit. To apply logistic regression analyses, a data matrix including 37 variables was constructed. The variables used in the forwards stepwise analyses are different measures of slope, aspect, elevation, stream power index (SPI), plan curvature, profile curvature, geology, geomorphology and relative permeability of lithological units. A total of 25 variables were identified as exerting strong influence on landslide occurrence, and included by the logistic regression equation. Wald statistics values indicate that lithology, SPI and slope are more important than the other parameters in the equation. Beta coefficients of the 25 variables included the logistic regression equation provide a model for landslide susceptibility in the Cekmece area. This model is used to generate a landslide susceptibility map that correctly classified 83.8% of the landslide-prone areas.

This volume of Journal of Physics: Conference Series contains invited and contributed peer-reviewed papers that were presented at the 16th International Symposium on Boron, Borides and Related Materials (ISBB 2008), which was held on 7-12 September 2008, at Kunibiki Messe, Matsue, Japan. This triennial symposium has a half-century long history starting from the 1st meeting in 1959 at Asbury Park, New Jersey. We were very pleased to organize ISBB 2008, which gathered chemists, physicists, materials scientists as well as diamond and high-pressure researchers. This meeting had a strong background in the boron-related Japanese research history, which includes the discovery of superconductivity in MgB2 and development of Nd-Fe-B hard magnets and of YB66 soft X-ray monochromator. The scope of ISBB 2008 spans both basic and applied interdisciplinary research that is centered on boron, borides and related materials, and the collection of articles defines the state of the art in research on these materials. The topics are centered on: 1. Preparation of new materials (single crystals, thin films, nanostructures, ceramics, etc) under normal or extreme conditions. 2. Crystal structure and chemical bonding (new crystal structures, nonstoichiometry, defects, clusters, quantum-chemical calculations). 3. Physical and chemical properties (band structure, phonon spectra, superconductivity; optical, electrical, magnetic, emissive, mechanical properties; phase diagrams, thermodynamics, catalytic activity, etc) in a wide range of temperatures and pressures. 4. Applications and prospects (thermoelectric converters, composites, ceramics, coatings, etc) There were a few discoveries of new materials, such as nanomaterials, and developments in applications. Many contributions were related to 4f heavy Fermion systems of rare-earth borides. Exotic mechanisms of magnetism and Kondo effects have been discussed, which may indicate another direction of development of boride. Two special sessions, 'Boron chemistry' and 'Superconductivity', were also held at the symposium. The session on Boron chemistry was planned to honor the scientific work in boron chemistry of Professor J Bauer on the occasion of his retirement. Many recent results were discussed in the session, and Professor Bauer himself introduced novel rare-earth-boron-carbon compounds RE10B7C10 (RE = Gd - Er) in his lecture. In the latter session, on the basis of recent discoveries of superconductivity in MgB2 and in β-boron under high pressure, the superconductivity of boron and related materials was discussed and the superconductivity of boron-doped diamond was also addressed. More than 120 participants from 16 countries attended the ISBB 2008, and active presentations (22 invited, 33 oral and 68 posters) and discussions suggest that research on boron and borides is entering a new phase of development. This volume contains 46 articles from 52 submitted manuscripts. The reviewers were invited not only from symposium participants but also from specialists worldwide, and they did a great job of evaluating and commenting on the submitted manuscripts to maintain the highest quality standard of this volume. Recent discoveries of superconductivity in boron under high pressure, synthesis of a new allotrope of boron and of various boron and boride nanostructures will lead this highly interdisciplinary field of science, which will further grow and gain attention in terms of both basic and applied research. In this context, we are very much looking forward to the next symposium, which will be held in Istanbul, Turkey, in 2011, organized by Professor Onuralp Yucel, Istanbul Technical University. Turkey currently has the world highest share of borate production and is expected to be involved more in boron-related research.

The Istanbul Zone in northwestern Turkey is a part of a larger continental fragment called the Rhodope-Pontide Fragment. The Istanbul Zone differs from its surroundings by its continuous, well-developed sedimentary sequence extending from the early-medial Ordovician to the early Carboniferous. The İstanbul Zone has a complicated deformation history related to the Hercynide (or Scythide), Cimmeride and Alpide orogenies. Although the region of Istanbul shows essentially no metamorphism and only a weak cleavage development, constraining the entire history of the deformation in the İstanbul Zone marginal fold and thrust belt is a difficult task, primarily due to the multiple deformation phases. But yet it is not impossible. The Palaeozoic sequence is cut by late Cretaceous plutonics together with dacitic and andesitic dykes. This arc magmatism is ascribed to the north-dipping subduction of the Neo-Tethyan ocean along the İzmir-Ankara-Erzincan suture. The Palaeozoic sequence is unconformably overlain by Permian and younger sedimentary strata. In this study a total of 523 samples were obtained from 48 sites around İstanbul and Kocaeli. 465 samples collected from Palaeozoic sedimentary rocks and 58 samples belong to the dykes that cut these sediments. Specimens were demagnetized in the laboratory by using both AF and thermal treatments depending on their effectiveness. After demagnetization treatments, 290 specimens showed stable demagnetization patterns and majority of these samples have a characteristic remanent magnetization component close to the present day geomagnetic field. Demagnetization studies demonstrate variable degrees of overprinting in a large number of samples. After the application of the tilt correction, %70 of the specimens failed the fold test at site level (early Ordovician siltstones; late Silurian-early Devonian limestones; late Devonian limestones; early Carboniferous turbidites). Rest of them clearly got scattered with increasing α95 and decreasing k values (mid Ordovician conglomerates; mid-late Devonian shales; late Ordovician-early Silurian sandstone and siltstones). This secondary magnetization, acquired during or after the folding event, constitutes evidence of pervasive remagnetization that can be caused by regional re-heating related to the Cretaceous arc magmatism. This suggestion contradicts the previous palaeomagnetic studies and requires further and detailed investigation on Palaeozoic sequence.

Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily. This is the first study to assess the magnitude of short- and long-term behavioural changes of the endangered Black Sea harbour porpoises (Phocoena phocoena relicta) in the presence of marine vessels within the Istanbul Strait. Markov chains were used to investigate the effect of vessel presence on the transition probability between behavioural states (diving, surface-feeding and travelling), and to quantify the effect on the behavioural budget and bout length (duration of time spent in a given state) of porpoises. Further, the changes on swimming directions of porpoises in relation to vessel speed and distance was investigated using generalized linear models. In vessel presence, porpoises were less likely to remain in a given behavioural state and instead more likely to switch to another state. Because of this, the bout length of all three behavioural states decreased significantly in the presence of vessels. The vessel effect was sufficiently large to alter the behavioural budget, with surface-feeding decreasing significantly in the presence of vessels. However, when taking into account the proportion of time that porpoises were exposed to vessels (i.e. 50%), the measured effect size was not large enough to significantly alter the animals' cumulative (diurnal) behavioural budget. Additionally, vessel speed and distance had a significant effect on the probability of porpoises showing a response in their swimming directions. The southern and middle sections of the Istanbul Strait, which have the heaviest marine traffic pressure, had the lowest porpoise sightings throughout the year. Conversely, northern sections that were exposed to a lesser degree of marine traffic hold the highest porpoise sightings. The effect shown in this study in combination with increasing human impacts within the northern sections should be considered carefully and species-specific conservation actions, including establishment of protected areas, should be put in place to prevent the long-term consequences of marine traffic on the Black Sea harbour porpoise population.

The North Anatolian Fault (NAF) in the northern Turkey regionally has right-lateral strike-slip motion. In the last decade, seismic activities have been migrating from east to west along the fault. In 1999, Izmit and Duzce Earthquakes were respectively occurred at 100 km and 200 km east of Istanbul, while it remains un-ruptured in the vicinity of Istanbul beneath the Sea of Marmara. In this region, onshore geodetic tools cannot be used and we instead used "seafloor acoustic extensometers" to detect slip deficit rate across the western part of the NAF (around 27.7 °E). A pair of extensometers can periodically measure precise range (about 3-4 mm precision per 1 km baseline) by observing round-trip time of acoustic signal between the two. We installed four instruments in September 2014 and an additional one in March 2015 across the NAF. We have recovered data for about 600-days through acoustic modem. By correcting travel-times for sound velocity using concurrently measured temperature, pressure and tilt change of instruments, we obtained 8-10 ±1 mm/yr of right-lateral movement at the site. Combing the result with on-shore GNSS data across the Sea of Marmara, we constructed a possible fault model. According to the model in Kaneko et al. (2013), we simply assume a bimodal slip condition on the fault plane that infinitely continues to the E-W direction; full-creep (25 mm/yr as is given at infinite distant from the fault plane) deeper than 15 km and applied an overriding partially locked layer (17 mm/yr slip deficit as is obtained by extensometers). We calculated 2-D displacement field in a homogeneous elastic half-space medium. With this model, N-S variation of on-shore GNSS data across the Sea of Marmara can be reasonably explained. However, due to the lack of GNSS site near the fault plane, constraint on the depth of the partially locked layer is not sufficient. We have newly installed GNSS sites, one of which is closer to the fault plane ( 10 km) than before and will be expected to provide much information on the fault condition.

Mankind has been expressing the breeding topic for thousands of years. Reproduction is the primary instinct of human beings and it is a social, cultural, medical issue. Demographic infertility is one of them, which is defined infertility as the inability to become pregnant with a live birth, within five years of regular sexual contact based upon a consistent union status in marriage maintaining a desire for a child with the lack of contraceptive use and non-lactating. A first mentions about infertility and surrogacy is discovered on a 4000-year-old clay tablet of marriage contract belonging to the Assyrian period exhibited at Istanbul Archeology Museum in Turkey. In conclusion, there are many different ways to solve infertility problems like surrogacy as mentioned even 4000 years ago in this Assyrian clay tablet of marriage contract as the first time in the literature. Medical treatments in relation to human infertility will continue to be the focus of social and cultural debates. Hence, more legislation and regulation will come in many countries to control the unauthorized exploitation of the patient.

To evaluate nurses' opinions on the violation and protection of their rights at public hospitals. The descriptive study was conducted between May and November 2013 at 11 hospitals affiliated with the Association of Public Hospitals in Istanbul, Turkey. Data was gathered using a questionnaire consisting of 59 questions on demographic characteristics, professions, and rights of nurses. Of the 1,808 respondents, 1,374(76%) said nurse's rights were not protected and 994(55%) believed that their rights were not protected at public hospitals. However, 1,027(56.8%) of the nurses stated that their right to job security was protected, while 1,448(80.1%) reported violation of their right to adequate pay and 1,289(71.3%) reported violation or non-recognition of the right to participate in the political decision-making processes that directly affect the nursing profession. Those who were middle-aged and those who had bachelor's degree believed their rights were not protected, and considered nursing as a weak profession that was unable to protect its rights (p<0.001). Nurses believed their rights, especially those about salary, were not sufficiently protected.

The North Anatolian Fault (NAF) is one of the most active faults worldwide, extending approximately 1,200 km from Eastern Turkey to the Northern Aegean Sea. During the 20th century series of damaging earthquakes occurred along the NAF, generally propagated westward towards Istanbul; the last one occurred in 1999 at Izmit, a city 80 km away from Istanbul. Within this scenario, the FP7 MARsite project (New Directions in Seismic Hazard assessment through Focused Earth Observation in Marmara Supersite), supported by EU, intends to collect, share and integrate multidisciplinary data (seismologic, geochemical, surveying, satellite, etc.) in order to carry out assessment, mitigation and management of seismic risk in the region of the Sea of Marmara. In the framework of the MARsite project, we performed the analysis and monitoring of the surface deformation affecting the Istanbul mega city by exploiting the large archives of X-band satellite SAR data, made available through the Supersites Initiatives, and by processing them via the advanced multi-temporal and multi-scale InSAR technique, known as the Small BAseline Subset (SBAS) approach. In particular, we applied the SBAS technique to a dataset of 101 SAR images acquired by the TerraSAR-X constellation of the German Space Agency (DLR) over descending orbits and spanning the November 2010 - August 2014 time interval. From,these images, we generated 312 differential interferograms with a maximum spatial separation (perpendicular baseline) between the acquisition orbits of about 500 m., that were used to generate, via the SBAS approach, mean deformation velocity map and corresponding ground time series of the investigated area. The performed InSAR analysis reveals a generalized stability over the Istanbul area, except for some localized displacements, related to subsidence and slope instability phenomena. In particular, we identified: (i) a displacement pattern related to the Istanbul airport, showing a mostly linear deformation trend with a velocity of about 1 cm/yr, although a slowdown effect is observed starting from early 2014, and (ii) a subsidence phenomenon in correspondence to Miniaturk park with a mean velocity value of about 1.5 cm/yr. Moreover, by benefiting from the recent launch of the C-band Sentinel-1A (S1A) satellite (April 2014), developed within the European Commission Copernicus Programme, we performed a more recent InSAR analysis of the Istanbul mega city and its surroundings by exploiting datasets collected during the October 2014 - December 2015 time interval. In such a way, we are able to investigate possible changes in the spatial and temporal deformation rates of the detected displacements over time with the aim to improve the comprehension of the deformation processes already occurred and/or occurring in this area. The obtained results, generated within the MARsite project, are expected to be available to scientific community through the Geohazards Exploitation Platform (GEP), an ESA platform aimed at supporting the exploitation of satellite EO data for geohazards, to be fully compliant with some of the major issues of the Supersites Initiative, as well as to foster the InSAR data sharing within a wider scientific community.

Istanbul is the largest city in Europe with a population of about 14 million and nearly 3.2 million registered vehicles. Considering that the city is at the junction of major transportation routes on both land and sea, emissions from all motor vehicles operating in the city and those that are in transit is the major source of pollution. The natural gas is used as the major heat source and the impact of other heating sources on the pollution episodes is not clearly known. During 19-29 December 2013 İstanbul metropolitan area experienced a severe PM10 episode with average episode concentration of 127µgm-3 . The episode was associated with a high pressure system with center pressure of 1030 mb residing over Balkans and north of Black Sea and thereby influencing Istanbul. We carried out simulations using the Weather Research and Forecasting model with Chemistry (WRF-CHEM) v3.5 to examine the meteorological conditions and to produce estimates of PM10 over Istanbul for 17-31 December 2013. The three nested domains was setup using 18, 6 and 2 km horizontal grid spacing with (90x90), (115x115) and (130x130) grid points in 1st, 2nd and 3rd domains, respectively. The each domain was run using one way nesting option after preparing the results from the mother domain as an input to subsequent inner domain. 34 vertical levels were used with the lowest layer depth of 15 m above the surface and extending to 15 km at the model top. The model was configured using the model options after many tests to find optimal model parameters and was initialized using global emissions data available publicly. The local emissions database is still in works and is not available to use in the model instead of global data. The estimated PM10 concentrations were compared against the observed conditions. This work shows the first attempt of using WRF-CHEM in Turkey to estimate the pollutant concentrations instead of using other air pollution models such as WRF/CMAQ combination. At the time of constructing this abstract, the model runs were still being conducted and the results will be discussed at the conference.

There are several methods that can be utilized for describing the landslide mechanisms. While some of them are commonly used, there are relatively new methods that have been proven to be useful. Obviously, each method has its own limitations and thus integrated use of these methods contributes to obtaining a realistic landslide model. The slopes of Küçükçekmece and Büyükçekmece Lagoons located at the Marmara Sea coast of İstanbul, Turkey, are among most specific examples of complex type landslides. The landslides in the area started developing at low sea level, and appears to ceased or at least slowed down to be at minimum after the sea level rise, as oppose to the still-active landslides that continue to cause damage especially in the valley slopes above the recent sea level between the two lagoons. To clarify the characteristics of these slope movements and classify them in most accurate way, Directorate of Earthquake and Ground Research of Istanbul Metropolitan Municipality launched a project in cooperation with Marmara Research Center of The Scientific and Technological Research Council of Turkey (TÜBİTAK). The project benefits the utility of the techniques of different disciplines such as geology, geophysics, geomorphology, hydrogeology, geotechnics, geodesy, remote sensing and meteorology. Specifically, this study focuses on two main axes of these techniques, namely: geological and geodetic. The reason for selecting these disciplines is because of their efficiency and power to understand the landslide mechanism in the area. Main approaches used in these studies are comprised of geological drills, inclinometer measurements, GPS surveys and SAR (both satellite and ground based) techniques. Integration of the results gathered from these techniques led the project team to comprehend critical aspects of landslide phenomenon in the area and produce precise landslide hazard maps that are basic instruments for a resilient urban development.

Suicidal behavior of young people is a topic of utmost importance because suicide is irreversible, and should be prevented. Knowing about the psychosocial background and the triggering events could help in preventing suicidal behavior. We therefore aimed at identifying psychosocial factors that may trigger suicidal behavior in youth. We analyzed retrospectively the standardized records of 2232 youths aged ≤25 years, who were treated after a suicide attempt at emergency units of public hospitals in Istanbul, Turkey during a period of 1 year. We describe this population according to sex and socio-economic conditions, like educational, occupational, relationship status and link them with their reported reasons for suicide attempts. The majority of patients were female (81.6%, N = 1822 females, 18.4%, N = 410 males). Independent of their educational and occupational background, patients indicated most frequently intra-familial problems (females 45.8%, males 30.5%), intrapersonal problems (females 19.9%, males 18.5%), and relationship problems (females 11.3%, males 23.9%) as triggering reasons. Because intra-familial problems were the most frequently reported triggers of suicide attempts, preventive measures should focus on handling intra-familial conflicts. As sex differences were observed for the second-most common trigger-reasons, prevention should also focus on differentially handling intrapersonal and relationship conflicts better.

Objective: The youth smoking rate is on the rise in Turkey. Although many marketing bans have been effectively implemented, regulations related to retail tobacco outlets have gone unnoticed and have not been effectively supervised. In this study, we aimed to show the lack of legal regulation related to the high retail tobacco outlet density with displays. Material and Methods: In the center of Edirne, the marketing environment, numbers and geographical distribution of retail tobacco outlets were documented and mapped with geographical positions. Results: There were 569 retail tobacco points of sale in 520 stores. We calculated one tobacco retail outlet per 270 people. This retail outlet density rate is above the national average and about four times higher than the density in Istanbul. Products especially attracting children, such as chocolate, sweet candy and chewing gum, were set up near the tobacco stands and were easy for children to recognize and reach. It can be seen on the city map that 47% of retail tobacco outlets are within 100 m of education, health or sport facilities. Conclusion: We concluded that one of the reasons for the increasing prevalence of cigarette use, especially among adolescents in Turkey, is deregulation of the retail tobacco marketing industry as a result of the privatization process of the national tobacco monopoly. Using mapping techniques can be useful in terms of controlling the retail marketing environment. PMID:25207039

Summary Turkey connects the Middle East, Europe, and Asia and has experienced major population movements. We examined the population structure and genetic relatedness of samples from three regions of Turkey using over 500,000 SNP genotypes. The data were analyzed together with Human Genome Diversity Panel data. To obtain a more representative sampling from Central Asia, Kyrgyz samples (Bishkek, Kyrgyzstan) were genotyped and analyzed. Principal component (PC) analysis reveals a significant overlap between Turks and Middle Easterners and a relationship with Europeans and South and Central Asians; however, the Turkish genetic structure is unique. FRAPPE, STRUCTURE, and phylogenetic analyses support the PC analysis depending upon the number of parental ancestry components chosen. For example, supervised STRUCTURE (K = 3) illustrates a genetic ancestry for the Turks of 45% Middle Eastern (95% CI, 42–49), 40% European (95% CI, 36–44), and 15% Central Asian (95% CI, 13–16), whereas at K = 4 the genetic ancestry of the Turks was 38% European (95% CI, 35–42), 35% Middle Eastern (95% CI, 33–38), 18% South Asian (95% CI, 16–19), and 9% Central Asian (95% CI, 7–11). PC analysis and FRAPPE/STRUCTURE results from three regions in Turkey (Aydin, Istanbul, and Kayseri) were superimposed, without clear subpopulation structure, suggesting the selected samples were rather homogeneous. Thus, this study demonstrates admixture of Turkish people reflecting the population migration patterns. PMID:22332727

This paper discusses the training of nurses in smoking cessation as part of routine patient care in Turkey. Formative research was carried out prior to training to identify challenges faced by smokers when trying to quit. Site visits to government hospitals and cessation clinics were conducted to observe health care provider-patient interactions involving behavior change. Four culturally sensitive cessation training workshops for nurses (n = 54) were conducted in Istanbul. Following training, nurses were debriefed on their experiences delivering cessation advice. Challenges to cessation counseling included lack of time and incentives for nurse involvement; lack of skills to deliver information about the harm of smoking and benefits of quitting; the medicalization of cessation through the use of pharmaceuticals; and hospital policy which devalues time spent on cessation activities. The pay-for-performance model currently adopted in hospitals has de-incentivized doctor participation in cessation clinics. Nurses play an important role in smoking cessation in many countries. In Turkey, hospital policy will require change so that cessation counseling can become a routine part of nursing practice, incentives for providing cessation are put in place, and task sharing between nurses and doctors is clarified. Nurses and doctors need to receive training in both the systemic harms of smoking and cessation counseling skills. Opportunities, challenges and lessons learned are highlighted.

Demirel, S

1994-01-01

Mr. Demirel says that at the root of all problems faced by society is population growth. He points out that with an annual population growth of about 2.5%, Turkey's standard of living will be low even if it is possible to feed the growing population, and he says Turkey's first goal should be to create public awareness of individual responsibilities. In this task, Mr. Demirel adds, the government, the parliament, educational institutions, the media, voluntary organizations, and scientists all have a role to play. Mr. Demirel states that Turkey's second goal should be to bring down the rate of population growth to around 1% within 20 years. The country's third goal, according to Mr. Demirel, should be to reduce the proportion of the population dependent on agriculture, since population growth is highest in rural areas and migration into urban areas is taxing city resources and creating slum communities. Mr. Demirel adds that dependence on agriculture will not create wealth for a nation and says that the goal should be to reduce Turkey's approximately 50% dependence on agriculture to about 10%, also within 20 years. Mr. Demirel goes on to point out that 50% of Turkey's population remains outside the social security umbrella and that in rural areas children represent a family's security during old age. It is therefore imperative to expand the social security umbrella. Turkey's fourth goal, as put forth by Mr. Demirel, should be to ensure orderly development. To increase the standard of living, the rate of population growth must be reduced while increasing the rate of development. He adds that it is also important to improve the distribution of wealth. This, says Mr. Demirel, is his fifth goal and can be achieved by overcoming the regional differences in rates of development with the aim of directing the inevitable migration from rural areas to nearby small cities, away from the large cities of Ankara, Istanbul, and Izmir. Mr. Demirel says that it will take time to achieve these goals, but that it is possible if the State adopts these goals as a national policy and if the Turkish people adopt the same goals as their own.

The aim of this study was to find out the effects of chemotherapy-related alopecia on body image and quality of life of Turkish women who have cancer with or without headscarves and factors affecting them. This descriptive study was conducted with 204 women who received chemotherapy at the Istanbul University Institute of Oncology, Turkey. The Patient Description Form, Body Image Scale and Nightingale Symptom Assessment Scale were used in data collection. Statistical analyses were performed using descriptive statistics and non-parametric tests. Logistic regression analysis was done to predict the factors affecting body image and quality of life of the patients. No difference was found between women wearing headscarves and those who did not in respect of their body image. However, women who wore headscarves who had no alopecia felt less dissatisfied with their scars, and women not wearing headscarves who had no alopecia have been feeling less self-conscious, less dissatisfied with their appearance. There was difference in terms of quality of life: women wearing headscarves had worse physical, psychological and general well-being than others. Although there were many important factors, multivariate analysis showed that for body image, having alopecia and wearing headscarves; and for quality of life, having alopecia were the variables that had considerable effects.

This study aimed to evaluate postural awareness and changes in posture and flexibility of students who took Clinical Pilates class as an elective course at the undergraduate level. The study conducted from 2013-2016 included 98 students who took Clinical Pilates class at the Department of Physical Therapy and Rehabilitation, School of Health Sciences, Istanbul Medipol University, Turkey. The flexibility levels of the study participants were measured before and after the Clinical Pilates education using finger-to-floor test and modified Schober's test. Observational posture analysis and postural awareness were recorded using the scale prepared by the researchers. The post-education evaluations showed that postural distortions were fixed, and a significant increase in the postural awareness of the students was observed compared with the pre-education period. The results of both modified Schober's test and finger-to-floor test, which were used to measure the flexibility levels, showed a statistically significant increase in post-education scores compared with those of the pre-education period. This study showed that the Clinical Pilates course increased postural awareness and flexibility of physical therapy students and fixed postural distortions. Thus, the inclusion of Clinical Pilates class in the undergraduate education is considered to be important.

Allergic diseases constitute a significant health problem in Turkey. According to a recent multicenter study, which used the ISAAC questionnaire, the mean prevalence of wheezing, rhinoconjunctivitis, and eczema in 10-yr-old school children during the past year was 15.8%, 23.5%, and 8.1%, respectively. A healthcare level system, regulated by Ministry of Health, is available in Turkey. Pediatric allergists and pediatric immunologists provide patient care at the tertiary level. Currently, 48 centers deliver care for allergic and immunologic diseases in children. There are 136 pediatric and 61 adult allergists/immunologists. Although the number of allergy/clinical immunology specialists is limited, these centers are capable of delivering many of the procedures required for the proper management and diagnosis of allergy/immunology. Pediatric allergy and/or immunology is a subspecialty lasting 3 yr and follows a 4-yr pediatric specialist training. Fellow training involves gaining knowledge in basic and clinical allergy and immunology as well as the performance and interpretation of laboratory procedures in the field of allergy and clinical immunology. The Turkish National Society of Allergy and Clinical Immunology (TNSACI) was officially established in 1989 and currently has 356 members. The society organizes a national congress annually and winter schools for fellowship training as well as training courses for patients and their relatives. TNSACI also has a strong representation in European Academy of Allergy and Clinical Immunology (EAACI) and European Society for Immunodeficiencies (ESID) through its participation in the executive committee, consensus reports, and initiatives in the diagnosis of allergic and immunologic diseases of children. The 30th Congress of the EAACI is also due to be held in Istanbul, Turkey, between June 11 and 15, 2011. © 2011 John Wiley & Sons A/S.

Measles is an important childhood infection targeted to be eliminated by the World Health Organization (WHO). Virus circulation has not been interrupted in the European Region because high vaccination rates could not be achieved among some countries of the WHO European Region including Turkey. The purpose of this study was to evaluate the laboratory findings of measles cases confirmed in the last nine years, to assess the epidemiological data of the cases, to determine the molecular genotyping studies and to emphasise the importance of laboratory-based surveillance in measles. From 2007 to 2010, only 18 imported cases were detected in Turkey. However, this number increased with a local outbreak of 111 cases in 2011, followed by another outbreak in 2012 in Istanbul that spread countrywide in the following two years; a total of 8661 laboratory-confirmed measles cases were reported from 2012 to 2015. After ELISA detection of a measles IgM-positive result in serum samples of potential measles cases, RT-PCR was performed with urine or nasopharyngeal swab samples of patients, and amplicons were subjected to sequencing. In the samples of 2010 and 2011, D4 and D9 genotypes were mainly detected; as of 2012, the D8 genotype has gained importance. Although D8 was also identified in 2014, in the same year genotype H1 viruses were detected in Turkey for the first time. Therefore, it is important to perform a genotypic analysis of the virus causing the outbreak, analyse epidemiological connections of the contact, determine the source of the outbreak and plan measures based on this information.

Excessive usage of the Internet can negatively affect health and health practices especially among youth. To examine the issue among Turkish students, this study determined the association between high-school students' attitudes towards Internet usage and their health behaviour. The sample (n = 2043) was randomly drawn from all students at two high schools in Turkey: one in Anatolia and one (a vocational school) in Istanbul. Data were collected using the Structured Questionnaire, Attitude Scale towards Internet Usage (ASTIU) and Adolescent Lifestyle Profile (ALP). The mean age of the students was 16.3 years, 77.7% were male and 96.9% used the Internet; mean duration of Internet use was 18.8 h/week. Female students had more positive attitudes towards Internet usage. Mean scores for ASTIU and ALP were 72.58 (SD 17.64) and 111.34 (SD 16.61) respectively, which were average levels. There was a statistically significant but weak overall negative correlation between adolescents' attitudes towards Internet usage and their health behaviour. Our results concur with studies in different cultures which suggest some negative effects, of heavy Internet use.

Value and Vulnerability Assessment of a Historic Tomb for Conservation

Monumental tombs reflect various social, cultural, architectural, religious, economic, and engineering features of a community. However, environmental weathering, natural disasters, poor maintenance, vandalism, and misuse unfortunately pose serious threats to these cultural assets. Historic monuments are often exposed to the highest risk due to their vulnerability. The Ottoman-style Nişancı Hamza Paşa tomb located in Karacaahmet Cemetery, Istanbul, the largest and oldest public cemetery in Turkey, is a case in point. The tomb consisting of six granite columns and a brick dome supported by six arches was constructed in 1605. Cracks, material loss, and decay as a result of adverse environmental effects and past earthquakes are evident. Therefore, this paper analyses the overall value of the tomb with respect to its historical, communal, evidential, and aesthetic aspects. Using the finite element approach and data on the tomb's material properties, a structural analysis under the self-weight and a time history analysis based on the earthquake ground motion data recorded in Duzce, Turkey, in November 1999 were conducted to encourage the conservation of this tomb and similar cultural heritage assets all over the world. The damage observed in the structure is congruent with the analysis results. PMID:25110732

Leather tanning may result in various occupational diseases. The aim of this study was to compare the relation between blood pressure levels and vocations in leather tanning. Our study was conducted in Turkey's leading leather process plant located in Tuzla organised industry zone, between March 11 and May 30, 2005. All leather plants that consented to participate in our study were included. The blood pressure, height and weight of the workers were measured. Their ages, educational levels, smoking habits and hypertension history were obtained via interviewing the subjects. The relation between three main factors, i.e. age, body mass index (BMI), working period, and hypertension were analysed through multiple logistic regression analysis. 40.4 percent (295) of 730 workers' blood pressure values were found to be within normal limits. 59.6 percent (435) were found to be hypertensive. The hypertension correlation remained significant, along with BMI and their working period (p-values were 0.0001 and 0.035, respectively). Our study demonstrated that BMI and working period have a key influence on the increased risk of hypertension, which leads us to consider the importance of occupational exposure. Different hypertension studies to be conducted in various occupational fields would likely be able to confirm our findings.

The postpartum period is a window of risk for psychological disturbances and particularly for depressive symptoms. This study explored the relationships between postpartum depression and prepartum depressive symptoms, marital adjustment, support from family, previous depressive symptomology, and pregnancy planning. A total of 128 women who were receiving prenatal care at a state hospital in Istanbul, Turkey, and who were in the last trimester of their pregnancy participated in the first phase of the study. Of these, eighty-seven women also participated in the second phase, during the 3-6 month postpartum period. The results indicated that depressed mood in the last trimester of pregnancy, family support, care and support from spouse, previous depression history, and unplanned pregnancy were significant risk factors for postpartum depressive symptoms; significant differences were found for study variables as a function of women's scores on the Edinburgh Postnatal Depression Scale in pregnancy and in the postpartum period. The recommendation is made to use screening tools, like the Edinburgh Postnatal Depression Scale, in the course of routine prenatal care, and to refer women with Edinburgh Postnatal Depression Scale scores above the cutoff score for further clinical examination.

Available in abstract form only. Full text of publication follows: Naturally occurring radioactive material (NORM) in concentrated forms arises both in industry and in nature where natural radioisotopes accumulate at particular sites. Technically enhanced naturally occurring radioactive materials (TE-NORM) often occurs in an acidic environment where precipitates containing radionuclides plate out onto pipe walls, filters, tank linings, etc. Because of the radionuclides are selectively deposited at these sites, radioactivity concentration is extremely higher than the natural concentration. This paper presents characterization and related considerations of TE-NORM wastes in Turkey. Generally, accumulation conditions tend to favour the build-up of radium. Asmore » radium is highly radio-toxic, handling, treatment, storage and disposal of such material requires careful management. Turkey has the only low level waste processing and storage facility (WPSF) in Istanbul. This facility has interim storage buildings and storage area for storage of packaged radioactive waste which are containing artificial radioisotopes, but there is an increasing demand for the storage to accept bulk concentrated TE-NORM wastes from iron-steel and related industries. Most of these wastes generated from scrap metal piles which are imported from other countries. These wastes generally contain radium. (authors)« less

Early Period of Modern Architecture in Turkey - A Case Study of Eskisehir

Karasozen, Rana

2017-10-01

Modern architecture in the Western World bore fruit at the beginning of the 20th Century in consequence of the process of modernity and seeking of the proper architecture for it. It was formed firstly towards the end of the 1920s. The main reason of this nonsynchronous development was the inadequacy of enlightenment and industrial revolution during the Ottoman Empire and the lack of formation of an intellectual infrastructure which provides the basis of modernity. However, the Ottoman Westernization occurring in the 19th century constituted the foundations of the Republic modernity founded in 1923. The earliest modern architectural designs in Turkey were first practised by European architects after the foundation of the Republic and internalised and practised extensively by the native architects afterwards. The early modern architecture of Turkey, named as “1930s Modernism”, continued until the beginning of the World War II. This period was formed in between the periods of first and second nationalist architecture movements. The early modern architecture period of Turkey was a period which high-quality designs were made. It was practised and internalised not only in big cities such as Ankara and in Istanbul, but also in the medium and small cities of the country. This situation was not just about a formal exception but about the internalisation of modernity by the society. Eskisehir is one of the most important pioneering cities of the Republic period in terms of industrial and educational developments. The earliest modern buildings were built as the public buildings by the state and non-citizen architects in the inadequate conditions of the country in terms of economy and professional people. The earliest modern houses of the city designed by these architects were the prototypes for the later practices which offered the citizens a new lifestyle. The modern houses were the symbols of prestige and status for the owners and the dwellers. The features of early modern buildings of Eskisehir as a medium-size city of Turkey will be examined in this study within the scope of the early modern architectural period of Turkey.

BACKGROUND Major bile duct injury is the most worrisome complication of cholecystectomy. There is no detailed data about the incidence or treatment-related costs of bile duct injuries in Turkey. We aimed to determine prevalence and therapeutic costs of patients with major biliary duct injuries managed in our department, and further estimate a projection of these parameters at the national level. MATERIAL AND METHODS All patients admitted due to bile duct injury during cholecystectomy from 2011 to 2014 were included. Healthcare costs were calculated by summing of their all treatment-related costs in Istanbul Medical Faculty. We collected 2014-2015 data on number of patients diagnosed with cholecystitis in Turkey, the number of cholecystectomies, and the number of the interventions performed following these initial surgeries, which were obtained from the Turkish Social Security Institution. RESULTS Forty-nine patients were enrolled and bilioenteric diversion was performed in 39 patients: 20.4% of patients had Bismuth II, 38.8% had Bismuth III, and 40.8% had Bismuth IV biliary stricture. Comparison of stricture types with total costs, days of hospitalization, and outpatient clinic costs revealed significant differences. Mean total cost of corrective surgeries was 9199 TRY. We estimated that 1.5% to 2.4% of patients who underwent cholecystectomy in Turkey have bile duct injury (including 0.3% with major bile duct injury). CONCLUSIONS New preventive strategies should be used to avoid bile duct injuries, which have a huge financial impact on the national economy.

Many new measuring devices have been developed so that broader psychometric measurements in the coronary artery disease, disease-specific health status measurements, and identification of the broader quality of life can be performed in the recent years. The study was intended to determine whether, and to what extent, MIDAS is a valid and reliable measurement to the patients suffering from myocardial infarction for the first time in Turkey. The research was conducted with the patients hospitalized and treated with myocardial infarction in the cardiology departments of 2 hospitals in Istanbul, Turkey, between 2007 and 2008. Psychometric evaluations of TR-MIDAS were used for validity studies; language validity, content validity, construct validity were examined. For reliability studies; the tool's internal consistency reliability, Cronbach's alpha reliability coefficient, and test-retest reliability were completed. The instrument's content validity index was determined to be "0.95". Principal component analysis revealed six factors with an eigenvalue >1.5. Cronbach's alpha was found to be 0.89 for total scale which was an acceptable value. The total's test-retest reliability was 0.51 (p<0.01). Data obtained at the end of the study supports that Turkish Myocardial Infarction Dimensional Assessment Scale is a valid and reliable instrument as a disease-specific scale to assess the patients' quality of life suffering from myocardial infarction in Turkey.

Water, forest, agricultural areas, grasslands, transport network, urban, airport- industrial units and barren land- mine land cover/use classes adapted from CORINE nomenclature were used as main land cover/use classes to identify. To fulfil the aims of this research, recently acquired dated 08/02/2016 Sentinel-2 and dated 22/02/2016 Landsat-8 images of Istanbul were obtained and image pre-processing steps like atmospheric and geometric correction were employed. Both Sentinel-2 and Landsat-8 images were resampled to 30m pixel size after geometric correction and similar spectral bands for both satellites were selected to create a similar base for these multi-sensor data. Maximum Likelihood (MLC) and Support Vector Machine (SVM) supervised classification methods were applied to both data sets to accurately identify eight different land cover/ use classes. Error matrix was created using same reference points for Sentinel-2 and Landsat-8 classifications. After the classification accuracy, results were compared to find out the best approach to create current land cover/use map of the region. The results of MLC and SVM classification methods were compared for both images.

Estimation of real properties depending on standards is difficult to apply in time and location. Regression analysis construct mathematical models which describe or explain relationships that may exist between variables. The problem of identifying price differences of properties to obtain a price index can be converted into a regression problem, and standard techniques of regression analysis can be used to estimate the index. Considering regression analysis for real estate valuation, which are presented in real marketing process with its current characteristics and quantifiers, the method will help us to find the effective factors or variables in the formation of the value. In this study, prices of housing for sale in Zeytinburnu, a district in Istanbul, are associated with its characteristics to find a price index, based on information received from a real estate web page. The associated variables used for the analysis are age, size in m2, number of floors having the house, floor number of the estate and number of rooms. The price of the estate represents the dependent variable, whereas the rest are independent variables. Prices from 60 real estates have been used for the analysis. Same price valued locations have been found and plotted on the map and equivalence curves have been drawn identifying the same valued zones as lines.

Implementing the effect of the rupture directivity on PSHA maps: Application to the Marmara Region (Turkey)

2016-04-01

In the present study we attempted to improve the seismic hazard assessment taking into account possible sources of epistemic uncertainty and the azimuthal variability of the ground motions which, at a particular site, is significantly influenced by the rupture mechanism and the rupture direction relative to the site. As a study area we selected Marmara Region (Turkey), especially the city of Istanbul which is characterized by one of the highest levels of seismic risk in Europe and the Mediterranean region. The seismic hazard in the city is mainly associated with two active fault segments which are located at about 20-30 km south of Istanbul. In this perspective first we proposed a methodology to incorporate this new information such as nucleation point in a probabilistic seismic hazard analysis (PSHA) framework. Secondly we introduced information about those fault segments by focusing on the fault rupture characteristics which affect the azimuthal variations of the ground motion spatial distribution i.e. source directivity effect and its influence on the probabilistic seismic hazard analyses (PSHA). An analytical model developed by Spudich and Chiou (2008) is used as a corrective factor that modifies the Next Generation Attenuation (NGA, Power et al. 2008) ground motion predictive equations (GMPEs) introducing rupture related parameters that generally lump together into the term directivity effect. We used the GMPEs as derived by the Abrahamson and Silva (2008) and the Boore and Atkinson (2008); our results are given in terms of 10% probability of exceedance of PSHA (at several periods from 0.5 s to 10 s) in 50 years on rock site condition; the correction for directivity introduces a significant contribution to the percentage ratio between the seismic hazards computed using the directivity model respect to the seismic hazard standard practice. In particular, we benefited the dynamic simulation from a previous study (Aochi & Utrich, 2015) aimed at evaluating the seismic potential of the Marmara region to derive a statistical distribution for nucleation position. Our results suggest that accounting for rupture related parameters in a PSHA using deterministic information from dynamic models is feasible and in particular, the use of a non-uniform statistical distribution for nucleation position has serious consequences on the hazard assessment. Since the directivity effect is conditional on the nucleation position the hazard map changes with the assumptions made. A worst case scenario (both the faults are rupturing towards the city of Istanbul) predicts up to 25% change than the standard formulation at 2 sec and increases with longer periods. The former result is heavily different if a deterministically based nucleation position is assumed.

Comprehensive data on the oral health status and dental treatment needs of the elderly population in Turkey are deficient. This pilot study determined the general and dental health status, perceived medical and dental treatment needs of an elderly population dwelling in residential homes in Istanbul. Subjects at three different residential homes, namely one belonging to the state and two supported by foundations in Istanbul (N=121, female: 63 and male: 58) were involved in this study. A detailed questionnaire was prepared and dental examinations were conducted. Information was collected related to age, education levels, financial status, current physical functional status, general health, mental health, previous dental history, current dental status, oral hygiene practices and denture hygiene of these elderly people. The prevalence of edentulism, the presence and type of dental prostheses, dental and denture status and denture cleanliness were further evaluated. The three most prevalent reported general health problems were associated with genito-urinary problems (24%) followed by cardiovascular (18%) and respiratory problems (14%) varying significantly between genders, with males suffering more from cardiovascular problems than females (p < 0.05). Females showed significantly higher gastrointestinal and orthopaedic problems than males (p < 0.05). Females were more frequently edentulous than males but denture hygiene was significantly better in females than in males (p < 0.05). Brushing frequency did not significantly increase denture hygiene (p = 0.6). More than one-third of the subjects had not been to the dentist within the previous 5-10 years, mainly due to lack of demand, followed by the cost of the dental care and fear. More than two-thirds of denture-wearing subjects wore their dentures only during eating. There was significant perceived dental treatment and care need for the sample population of elderly studied. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

The professional performance level of their alumni is one of the quality indicators of educational institutions. Nursing education institutions can use their alumni's performance analysis results to enhance their curricula, eliminate deficiencies, improve the quality of education and graduate more highly qualified nurses. This is a descriptive, cross-sectional and comparative study, which aimed to determine the professional performances of nurses who graduated from the same nursing faculty. The study sample included alumni of Turkey's first nursing faculty, part of the nation's first public university in Istanbul, and their administrative supervisors. The study data were collected using the self-assessment forms of 314 alumni who worked as bedside nurses in 36 Istanbul hospitals, and 314 evaluations by the 195 nurse managers who supervised them. The study's response rate was 82.6%. To collect the study data, the researchers created a performance evaluation form based on the relevant literature. The same form was administered both to the nurse managers and the alumni. The researchers obtained ethical board approval and official permissions from the relevant hospitals to conduct the study. The study data were analyzed by a statistics expert. According to the study results, the alumni's perceptions of themselves as well as the nurse managers' perceptions of the alumni were different from those of the other nurses with undergraduate degrees in terms of professional knowledge, expectations and ideals. The performance evaluation results showed that the alumni evaluated themselves more positively than their managers did. It was determined that there were highly significant differences (p=0.000) between the values provided by the five sub-dimensions of the scale and the total scale. In addition, the performance level was low in the sub-dimension focusing on research, and there was a significant difference in this sub-dimension (p=0.040). The study found that the alumni mainly had better evaluations of their own performances than their nurse managers, and that the research skills of the alumni should be enhanced.

The effect of weathering in the Buyukmelen River basin on the geochemistry of suspended and bed sediments and the hyrogeochemical characteristics of river water, Duzce, Turkey

NASA Astrophysics Data System (ADS)

Pehlivan, Rustem

2010-07-01

The Buyukmelen River is expected to be a water source that can supply the drinking water needs of Istanbul until 2040. The drinking and utility water needs of Istanbul are to transport water from the Buyukmelen River to Istanbul via pipeline and pump it into the Alibeykoy and Omerli reservoirs when their water levels drop. The Buyukmelen River is located in the province of Duzce in 170 km east of Istanbul and its water basin is approximately 2250 km 2. The Buyukmelen River flows muddy in the rainy season and into the Black Sea. The chemical compositions of natural waters alter due to interaction with geological formations, physical and chemical weathering of various rocks and the effects of mining and agricultural production. A research was conducted at the Buyukmelen River basin to determine the effects of hydrological processes. Therefore, the samples of rocks, soil, stream water, suspended and bed sediment were collected from the Buyukmelen River basin. Geochemical and water chemistry analyses of samples were performed at ALS Chemex laboratories, Canada. The bed sediments contain quartz, calcite, plagioclase, amphibole and clay minerals. The clay minerals in the suspended and bed sediment samples are kaolinite, smectite and illite. The water samples collected from the Aksu, Kucukmelen, Asarsu and Ugursuyu streams and the Buyukmelen River in winter (December 2005) and summer (June 2006) periods are rich in Ca and HCO 3 ions. The ions most abundant in rainfall sample are HCO 3 and Na. The ion compositions of surface waters have increased due to the weathering of limestone, agglomerate and volcanic sandstones, light acidic rainfall, semi-arid Black Sea climate in the Buyukmelen basin. The suspended sediment amount of the Buyukmelen River in the rainy season (December 2005) is 174 mg/l. According to the water contamination regulation of Turkey, the Buyukmelen Rivers belongs to quality class 4 based on Al ion and to quality class 3 based on Fe ion in winter period, and to quality class 2 based on Mn concentration in summer period. Chemical index of alteration (CIA) indices observed in the suspended and bed sediments (average of 55) suggest that their source area underwent moderate degrees of chemical weathering processes. According to Upper Continental Crust (UCC) values, the suspended sediment was rich in elements such as Fe 2O 3, CaO, MgO, MnO, TiO 2, P 2O 5, V, Cr, Co, Cu, Zn, As, Cd, Sb, Hg and Pb. The element concentrations of the suspended sediments were related to size fractionation, mainly of clay content. The mentioned enrichment was contributed by agglomerate, basalt, volcanic sandstone and graywacke from rocks in the study area. Source of ions such as Al, Fe, Mn, Ba, Cr, Co, Cu, Ni, Ti and Hg and major in the Buyukmelen River is interaction with rocks such as the agglomerate, basalt, andesite, volcanic sandstone and graywacke. As suggested by Singh et al. (2005), before weathering of some rocks in the Buyukmelen River basin, it was determined that they were graywacke and literanite based on the geochemistry of the suspended and bed sediments.

2015-12-01

Migration from rural areas to city centers and their surroundings is an important problem of not only our country but also the countries that under development stage. This uncontrolled and huge amount of migration brings out urbanization and socio - economic problems. The demand on settling the industrial areas and commercial activities nearby the city centers results with a negative change in natural land cover on cities. Negative impacts of human induced activities on natural resources and land cover has been continuously increasing for decades. The main human activities that resulted with destruction and infraction of forest areas can be defined as mining activities, agricultural activities, industrial / commercial activities and urbanization. Temporal monitoring of the changes in spatial distribution of forest areas is significantly important for effective management and planning progress. Changes can occur as spatially large destructions or small infractions. Therefore there is a need for reliable, fast and accurate data sources. At this point, satellite images proved to be a good data source for determination of the land use /cover changes with their capability of monitoring large areas with reasonable temporal resolutions. Spectral information derived from images provides discrimination of land use/cover types from each other. Developments in remote sensing technology in the last decade improved the spatial resolution of satellites and high resolution images were started to be used to detect even small changes in the land surface. As being the megacity of Turkey, Istanbul has been facing a huge migration for the last 20 years and effects of urbanization and other human based activities over forest areas are significant. Main focus of this study is to determine the destructions and infractions in forest areas of Istanbul, Turkey with 2.5m resolution SPOT 5 multi-temporal satellite imagery. Analysis was mainly constructed on threshold based classification of multi-temporal vegetation index data derived from satellite images. Determined changes were exported to GIS environment and spatial overlay and intersection analyses were performed with use of forest type maps and authorized area maps in order to demonstrate the actual situation of destructions and infractions.

In many countries, access to general health and eye care is related to an individual's socioeconomic status (SES). We aimed to examine the prevalence of oculo-visual disorders in children in Istanbul Turkey, drawn from schools at SES extremes but geographically nearby. Three school-based vision screenings (presenting distance visual acuity, cover test, eye assessment history, colour vision, gross stereopsis and non-cycloplegic autorefraction) were conducted on 81% of a potential 1014 primary-school children aged 4-10 years from two private (high SES) schools and a nearby government (low SES) school in central Istanbul. Prevalence of refractive errors and school-based differences were analysed using parametric statistics (ANOVA). The remaining oculo-visual aspects were compared using non-parametric tests. Of the 823 children with mean age 6.7 ± 2.2 years, approximately 10% were referred for a full eye examination (8.2% and 16.3% of private/government schools respectively). Vision had not been previously examined in nearly 22% of private school children and 65% of government school children. Of all children, 94.5% were able to accurately identify the 6/9.5 [LogMAR 0.2] line of letters/shapes with each eye and 86.6% the 6/6 line [LogMAR 0], while 7.9% presented wearing spectacles, 3.8% had impaired colour vision, 1.5% had grossly impaired stereo-vision, 1.5% exhibited strabismus, 1.8% were suspected to have amblyopia and 0.5% had reduced acuity of likely organic origin. Of the 804 without strabismus, amblyopia or organic conditions, 6.0% were myopic ≤ - 0.50DS, 0.6% hyperopic ≥ + 2.00DS, 7.7% astigmatic ≥1.00 DC and 6.2% anisometropic ≥1.00DS. The results highlight the need for general vision screenings for all children prior to school entry given the varied and different pattern of visual problems associated with lifestyle differences in two populations raised in the same urban locale but drawn from different socioeconomic backgrounds.

Few studies have investigated breast health programs to promote rates of having a mammography, clinical breast examination and breast self-examination among non-adherent Turkish women. To determine the effectiveness of a breast health promotion program on mammography and clinical breast examination use, breast self-examination frequency and proficiency (breast self-examination skills and lump detection), breast health knowledge and health beliefs about breast cancer screening in a sample of Turkish women. Experimental (pretest-posttest control group). A community-based setting in Istanbul, Turkey. 190 Non-adherent women (intervention group=97, control group=93) aged 41 and older, residing in Istanbul, Turkey. The intervention group (n=97) received a 120-min breast health promotion program based on health belief model including a breast health education, film, breast self-examination instruction, and a booklet, a calendar, a card designed specifically for the study. The control group (n=93) received general information except breast health. Data were collected before the program, immediately after the program, and at 3- and 6-month post-program. The outcome measures are the mammography, clinical breast examination, and breast self-examination frequency, breast self-examination proficiency, breast health knowledge, and health beliefs (perceived susceptibility to breast cancer, benefits to mammography and breast self-examination, barriers of mammography and breast self-examination, confidence in performing breast self-examination). The breast health promotion program significantly increased breast self-examination frequency and proficiency and breast health knowledge. No significant differences existed in mammography and clinical breast examination rates between the two groups at 6 months. The program was effective in increasing perceived susceptibility to breast cancer, perceived benefits of mammography and breast self-examination, and confidence of breast self-examination. No significant difference was found between the two groups for perceived barriers to mammography. The breast health promotion program was effective in increasing breast self-examination frequency and proficiency in a sample of Turkish women. In addition, it appears to be useful in raising the knowledge of breast health, enhancing confidence in performing breast self-examination, and increasing most health belief levels.

Objective: Contrast media (CM) are a major cause of nephropathy in high-risk patients. The aim of this study was to examine the effects of carnitine (CAR) in advanced nephrotoxicity due to CM administration in rats with glycerol-induced renal functional disorder. Methods: 40 rats were divided randomly into five groups (n = 8): (1) healthy group; (2) glycerol only (GLY); (3) glycerol and CM (GLY + CM); (4) glycerol, CM and 200 mg kg−1 carnitine (CAR200, Carnitene®; Sigma-tau/Santa Farma, Istanbul, Turkey); and (5) glycerol, CM and 400 mg kg−1 carnitine (CAR400). Kidney injury was induced with a single-dose, intramuscular injection of 10 ml kg−1 body weight (b.w.) of GLY. CAR was administered intraperitoneally. CM (8 ml kg−1 b.w. iohexol, Omnipaque™; Opakim Medical Products, Istanbul, Turkey) was infused via the tail vein to the rats in Groups 3–5. Results: l-carnitine administration significantly decreased serum creatinine and blood urea nitrogen levels. Superoxide dismutase and glutathione activity increased significantly in the treatment groups compared with the nephrotoxic groups. CAR400 significantly reduced malondialdehyde levels to healthy levels. In the treatment groups, tumour necrosis factor (TNF)-α, transforming growth factor 1β, interleukin 1β and caspase-3 gene expression decreased compared with the nephrotoxic groups. TNF-α and nuclear factor kappa-beta (NF-κB) protein expression increased after CM and CAR administration reduced both TNF-α and NF-κB expressions. Histopathologically, hyaline and haemorrhagic casts and necrosis in proximal tubules increased in the nephrotoxicity groups and decreased in the CAR groups. Conclusion: The results reveal that l-carnitine protects the oxidant/antioxidant balance and decreases proinflammatory cytokines and apoptosis in CM-induced nephrotoxicity in rats with underlying pathology. Advances in knowledge: Depending on the underlying kidney pathologies, the incidence of CM-induced nephropathy (CIN) increases. Therefore, this is the best model to represent clinically observed CIN.

The cultural background of Islam and its religious practices as well as hospital administration and staff training, living conditions, the status of women, and child rearing were the topics of a study by 3 child care nurses in Turkey. The purpose of this study was to better understand the situation of Turkish immigrants and the possible conflicts they experience with Swedish society. Public school attendance is compulsory for a period of 5 years starting at age 7 (3 additional years may be required in the future). Since Ataturk's reforms in 1926, schools have been coeducational, and attendance is 80-90% even in remote rural areas governed by district registrars. The Red Crescent runs school health centers staffed by a doctor and a nurse. Illiterate women take a free 6-month course for 8 hours a day to learn reading and writing. There are state supported hospitals, workers' hospitals funded by unions, university clinics for the education of physicians, and small private clinics in Turkey. Most women marry at 14-18 years of age. The population is growing by 1 million annually. About 80% of urban women give birth in hospitals vs. only 20% of rural women. Women with high-risk pregnancies are placed in special birthing wards. Ultrasound is not used, nor is epidural anesthesia; only pethidine (Meperidine) injections are given to mitigate pain. Midwives play a central role in family planning, giving advice about contraceptives (IUDs are most prevalent, but the pill is gaining ground). Abortion is allowed for medical reasons, but a new law is being debated. Prostitutes get regular medical examinations to control venereal diseases. Pregnant women receive paid leave for 42 days before and after delivery. Education of nurses takes place in nursing schools of major cities like Istanbul, Ankara, and Izmir. Tuition, room, and board are free provided by the state. The course of study is 4 years and nurses can also work as midwives due to a shortage in their ranks. Elementary midwife training schools are mostly in the countryside, and their graduates visit newborn babies once a week for the first 40 days and once a month up to age 3. They also dispense vaccinations. Child care centers provide care for children between the ages of 3-6, at which point the schools take over.

To compare the effects of sedation and general anesthesia for surgically assisted rapid palatal expansion (SARPE). This randomized prospective study included 30 patients who were scheduled for SARPE, and was performed between January 2008 to February 2010 in the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Marmara University, Istanbul, Turkey. Patients were allocated into Group S - midazolam + fentanyl sedation (n=15), and Group G - general anesthesia (n=15). Hemodynamic parameters, duration of anesthesia, surgery, recovery time, time to discharge, visual analogue scale (VAS) pain scores at 30 minutes (min), one hour (hr), 4 hours, 12 hours, and 24 hours, first consumption of analgesic time, total amount of consumption of analgesics, patient and surgeon satisfaction, nausea, and vomiting were recorded. Analgesic time was significantly longer in Group S (p=0.008), and total analgesic consumption was significantly lower in Group S than in Group G (p=0.031). Patient satisfaction was statistically higher in Group S (p=0.035). At 30 min, one hr, and 12 hrs, VAS satisfaction scores in Group S were statistically lower than those in Group G, and at 4 hrs and 24 hrs there was no statistical difference in VAS scores for both groups. The use of sedation for outpatient SARPE resulted in lower pain scores at discharge, lower analgesic consumption, and greater patient satisfaction.

Pyrochlore general formula of A2B2X7 where A and B are cations and X is an anion Pyrochlore compounds exhibit semiconductor, metallic or ionic conduction properties, depending on the doping, compositions/ substituting variety of cations and oxygen partial pressure. Ion beam irradiation can induce the structural disordering by mixing the cation and anion sublattices, therefore we aim to inevestigate effects of irradiation in pyrochlore compounds. In this study, Eu and Yb-doped Bi1.5Zn0.92Nb1.5O6.92 (Eu-BZN, Yb-BZN) Doping effect and single phase formation of Eu-BZN, Yb-BZN was characterized by X-ray diffraction technique (XRD). Radiation-induced effect of 85 MeV C6+ ions on Eu-BZN, Yb-BZN was studied by XRD, scanning electron microscopy (SEM) and temperature dependent dielectric measurements at different fluences. XRD results revealed that the ion beam-induced structural amorphization processes in Eu-BZN and Yb-BZN structures. Our results suggested that the ion beam irradiation induced the significant change in the temprature depndent dielectric properties of Eu-BZN and Yb-BZN pyrochlores due to the increased oxygen vacancies as a result of cation and anion disordering.

Cardiovascular disease is the number one cause of death worldwide. However, there is not enough data exploring student nurses' understanding, knowledge, and awareness of cardiovascular disease. To investigate knowledge of cardiovascular disease and its risk factors among undergraduate nursing students, with an emphasis on understanding of cardiovascular disease as the primary cause of mortality and morbidity, both in Turkey and worldwide. This cross-sectional survey assessed 1138 nursing students enrolled in nursing schools in Istanbul, Turkey. Data were collected using the Cardiovascular Disease Risk Factors Knowledge Level (CARRF-KL) scale and questions from the Individual Characteristics Form about students' gender, age, level of education, and family cardiovascular health history, as well as smoking and exercise habits. Respondents demonstrated a high level of knowledge about cardiovascular disease, with years of education (p < 0.001), gender (p < 0.001), and high school type (p < 0.05) all significantly associated with CARRF-KL scores. However, more than half of the students were not aware that cardiovascular disease is the primary cause of mortality and morbidity in Turkey and worldwide. The majority of the respondents' body mass index (87%) and waist circumference values (females: 90.3%, males: 94.7%) were in the normal range and most were non-smokers (83.7%). However, more than half of the students did not exercise regularly and had inadequate dietary habits. Although students were knowledgeable about cardiovascular disease and associated risk factors, there were significant gaps in their knowledge; these should be addressed through improved nursing curricula. While students were generally healthy, they could improve their practice of health-promoting behaviors. © The European Society of Cardiology 2014.

A Simple Correlation for Neutron Capture Rates from Nuclear Masses

DOE Office of Scientific and Technical Information (OSTI.GOV)

Couture, Aaron Joseph

Recent studies of neutron capture performed at LANL have revealed a previously unrecognized connection between nuclear masses and the average neutron capture cross section. A team of three scientists from Los Alamos (P-27), Yale Univ., and Istanbul Univ. (Turkey) recently discovered this connection and have published their results as a Rapid Communication in Physical Review C. Neutron capture is a reaction in which a free neutron is absorbed by the nucleus, keeping the element unchanged, but changing isotopes. This reaction is typically exothermic. As a result, the reaction can proceed even when many other reaction channels are closed. In anmore » astrophysical environment, this means that neutron capture is the primary mechanism by which all of the elements with atomic number greater than nickel are produced is neutron capture.« less

The use of generic drugs has increased significantly in recent years. Since generic drugs are available at a lower cost, they provide an opportunity for savings in drug expenditure. Thus, use of generic drugs is encouraged especially in developing countries. There are only a few studies concerning the perceptions and attitudes of the healthcare providers and patients towards generic drug use. Methods The present study was conducted by a face to face questionnaire in the Kadikoy district of Istanbul in April 2010. From randomly chosen respondents, 68 pharmacists, 56 prescribers and 101 patients consented to participate in the study. Results Thirty one and 32 % of the pharmacists and prescribers, respectively, expressed that they believed that the generics did not differ from the original drugs, whereas only 24% of the patients believed so. Forty percent of the pharmacists and 82% of the prescribers told that they were unsure about the bioequivalence of the generics. Ten percent of the patients claimed that they immediately accept generic substitution by the pharmacist, while 26% accepted it if it was substituted by the prescriber. Cost was the most important factor taken into consideration about generic substitution (92% for prescribers; 83% for patients and 82% for pharmacists). Conclusions Our findings demonstrated that healthcare providers as well as the drug consumers have insufficient knowledge about generic drugs. Therefore, they should be better educated with respect to generic substitution. PMID:24155838

This study was to determine pregnant women's knowledge and attitudes towards stem cells and cord blood banking in Istanbul, Turkey. Stem cell research is one of the most important and, at the same time, the most controversial topics of science and technology today. Nurses need to understand stem cell research so they can enter the debate on this issue. They can become important sources of information in order to help parents understand the issues. This exploratory descriptive study was conducted in two antenatal outpatient clinics in Istanbul. The sample consisted of 334 pregnant women during routine prenatal visits. Data were collected in interviews by using an interview form developed by the researchers according to the literature. The form included demographic characteristics of participants and 20 questions about stem cells, storing cord blood and banking and 10 independent attitude statements. The majority of the participants had a lack of knowledge about stem cells and cord blood banking and wanted more information. Before pregnancy, they received some information through the media (newspaper, Internet, television, etc.), but unintentionally. It was determined that they wanted information before becoming pregnant, more from their obstetrician but also from nurses and midwives. The majority also wanted to store their infants' cord blood and stated that they would be more likely to choose a public cord blood bank. Those giving ante- and perinatal care need to offer accurate and scientific counselling services on this subject to parents who need to be informed.

The ANN method has been applied by means of multilayered feedforward neural networks (MLFNs) by using different macroeconomic variables such as the exchange rate of USD/TRY, gold prices, and the Borsa Istanbul (BIST) 100 index based on monthly data over the period of January 2000 and September 2014 for Turkey. Vector autoregressive (VAR) method has also been applied with the same variables for the same period of time. In this study, different from other studies conducted up to the present, ENCOG machine learning framework has been used along with JAVA programming language in order to constitute the ANN. The training of network has been done by resilient propagation method. The ex post and ex ante estimates obtained by the ANN method have been compared with the results obtained by the econometric forecasting method of VAR. Strikingly, our findings based on the ANN method reveal that there is a possibility of financial distress or a financial crisis in Turkey starting from October 2017. The results which were obtained with the method of VAR also support the results of ANN method. Additionally, our results indicate that the ANN approach has more superior prediction performance than the VAR method. PMID:26550010

Previous research has shown daily salt intakes in Turkey to be far above the recommended limits. Knowing the sources of dietary salt could form a basis for preventive strategies aimed towards salt reduction. This study aimed to investigate dietary sources of salt in Turkey. A sub-group ( n = 657) was selected from the PatenT2 study population, which represented the urban and rural areas of 4 major cities (Ankara, Istanbul, Izmir, and Konya). A questionnaire inquiring about sociodemographic characteristics, medical histories, detailed histories of diet, and salt consumption was completed. Participants were asked to collect a 24-h urine sample and to record their food intake (dietary recall) on the same day. Of 925 participants selected, 657 (71%) provided accurate 24-h urine collections, based on creatinine excretion data. The mean daily 24-h urinary sodium excretion was 252.0 ± 92.2 mmol/day, equal to daily salt intake of 14.8 ± 5.4 g. Of the 657 participants with accurate 24-h urine collections, 464 (70%) provided fully completed dietary recalls. Among these 464 participants, there was a significant difference between the 24-h urinary sodium excretion-based salt intake estimation (14.5 ± 5.1 g/day) and the dietary recall-based salt intake estimation (12.0 ± 7.0 g/day) ( p < 0.001). On the other hand, a positive correlation was obtained between the dietary recall-based daily salt intake and 24-h urinary sodium excretion-based daily salt intake ( r = 0.277, p < 0.001). Bread was the main source of salt (34%) followed by salt added during cooking and preparing food before serving (30%), salt from various processed foods (21%), and salt added at the table during food consumption (11%). Conclusively, this study confirmed a very high salt intake of the adult population in four major cities in Turkey. The present findings support the emerging salt reduction strategy in Turkey by promoting lower salt content in baked bread, and less salt use in habitual food preparation and during food consumption in the home.

Wolbachia are maternally transmitted bacteria that can manipulate their hosts' reproduction causing cytoplasmic incompatibility (CI). CI is a sperm-egg incompatibility resulting in embryonic death. Due to this sterilising effect on mosquitoes, Wolbachia are considered for vector control strategies. Important vectors for arboviruses, filarial nematodes and avian malaria, mosquitoes of Culex pipiens complex are suitable for Wolbachia-based vector control. They are infected with Wolbachia wPip strains belonging to five genetically distinct groups (wPip-I to V) within the Wolbachia B supergroup. CI properties of wPip strongly correlate with this genetic diversity: mosquitoes infected with wPip strains from a different wPip group are more likely to be incompatible with each other. Turkey is a critical spot for vector-borne diseases due to its unique geographical position as a natural bridge between Asia, Europe and Africa. However, general wPip diversity, distribution and CI patterns in natural Cx. pipiens (s.l.) populations in the region are unknown. In this study, we first identified wPip diversity in Turkish Cx. pipiens (s.l.) populations, by assigning them to one of the five groups within wPip (wPip-Ito V). We further investigated CI properties between different wPip strains from this region. We showed a wPip fixation in Cx. pipiens (s.l.) populations in Turkey by analysing 753 samples from 59 sampling sites. Three wPip groups were detected in the region: wPip-I, wPip-II and wPip-IV. The most dominant group was wPip-II. While wPip-IV was restricted to only two locations, wPip-I and wPip-II had wider distributions. Individuals infected with wPip-II were found co-existing with individuals infected with wPip-I or wPip-IV in some sampling sites. Two mosquito isofemale lines harbouring either a wPip-I or a wPip-II strain were established from a population in northwestern Turkey. Reciprocal crosses between these lines showed that they were fully compatible with each other but bidirectionally incompatible with wPip-IV Istanbul infected line. Our findings reveal a high diversity of wPip and CI properties in Cx. pipiens (s.l.) populations in Turkey. Knowledge on naturally occurring CI patterns caused by wPip diversity in Turkey might be useful for Cx. pipiens (s.l.) control in the region.

The contribution of engineering surveys by means of GPS to the determination of crustal movements in Istanbul

Global Navigation Satellite Systems (GNSS) are space based positioning techniques and widely used in geodetic applications. Geodetic networking accomplished by engineering surveys constitutes one of these tasks. Geodetic networks are used as the base of all kinds of geodetic implementations, Co from the cadastral plans to the relevant surveying processes during the realization of engineering applications. Geodetic networks consist of control points positioned in a defined reference frame. In fact, such positional information could be useful for other studies as well. One of such fields is geodynamic studies that use the changes of positions of control stations within a network in a certain time period to understand the characteristics of tectonic movements. In Turkey, which is located in tectonically active zones and struck by major earthquakes quite frequently, the positional information obtained in engineering surveys could be very useful for earthquake related studies. For this purpose, a GPS (Global Positioning System) network of 650 stations distributed over Istanbul (Istanbul GPS Triangulation Network; abbreviated IGNA) covering the northern part of the North Anatolian Fault Zone (NAFZ) was established in 1997 and measured in 1999. From 1998 to 2004, the IGNA network was extended to 1888 stations covering an area of about 6000 km2, the whole administration area of Istanbul. All 1888 stations within the IGNA network were remeasured in 2005. In these two campaigns there existed 452 common points, and between these two campaigns two major earthquakes took place, on 17 August and 12 November 1999 with a Richter scale magnitude of 7.4 and 7.2, respectively. Several studies conducted for estimating the horizontal and vertical displacements as a result of these earthquakes on NAFZ are discussed in this paper. In geodynamic projects carried out before the earthquakes in 1999, an annual average velocity of 2-2.5 cm for the stations along the NAFZ were estimated. Studies carried out using GPS observations in the same area after these earthquakes indicated that point displacements vary depending on their distance to the epicentres of the earthquakes. But the directions of point displacements are similar. The results obtained through the analysis of the IGNA network also show that there is a common trend in the directions of point displacements in the study area. In this paper, the past studies about the tectonics of Marmara region are summarised and the results of the displacement analysis on the IGNA network are discussed.

Doctors in Greece face the possibility of encountering a person that has suffered torture, especially since the high rates of refugees' and migrants' inflows that took place over the last years. In order to assess the awareness and the knowledge of doctors and senior medical students in Greece regarding a manual on effective investigation and documentation of torture such as Istanbul Protocol (official United Nation document since 1999), a cross-sectional study was conducted using a structured anonymous questionnaire. The sample was doctors practicing in public hospitals in Greece, doctors volunteering at a non-governmental organization (NGO) and undergraduate medical students in their final year of studies in the Medical School of National and Kapodistrian University of Athens. The data were analyzed using IBM SPSS version 23, using descriptive statistics and statistical significance tests.In a total of 289 participants, the mean total score of Istanbul Protocol knowledge was 4.43 ± 1.104 (the maximum possible score was 10) and the mean total score of Istanbul Protocol awareness was 2.04 ± 1.521 (the maximum possible score was 10). The most important conclusion was that among doctors and senior medical students, there seem to be knowledge, awareness, and information deficit about Istanbul Protocol and several issues relating to torture. The overall research outcome highlights the need for the development of a relevant informative/educational program, in order to cover the corresponding existing needs of the population of doctors in Greece.

Effects of tobacco smoking and alcohol use on risks of cancers of the larynx and lung have been evaluated extensively in industrialized countries. Few studies on the effect of these risk factors have been reported from developing countries. We conducted a case-control study to evaluate risks of laryngeal and lung cancers in men by subsite and cell type in relation to smoking and alcohol drinking in Turkey, a country where smoking and alcohol consumption patterns are different from those in industrialized countries. We identified 832 laryngeal and 1,210 lung cancer cases and 829 controls with information on smoking and alcohol use (amount and duration) and histologic cell type from an oncology treatment center of a Social Security Agency hospital in Istanbul, Turkey, admitted between 1979 and 1984. Both laryngeal and lung cancer showed significant associations with smoking and alcohol drinking, but no monotonic dose-response was obtained for alcohol drinking. Among smokers, the highest risks were observed in the supraglottis region of the larynx (odds ratio [OR] = 4.1) after adjustment for age and alcohol use. Among alcohol drinkers, the highest risks were observed in the glottis region of the larynx (OR = 1.7) after adjustment for age and smoking. In the analysis by the cell type of lung cancer among ever-smokers, small cell type showed the highest risk (OR = 5.4), while it showed no association with alcohol drinking. Cumulative cigarette use (pack-years) and number of cigarettes per day showed stronger associations than years smoked for both cancer sites. The relative risks of joint exposure to smoking and alcohol were 12.2 for laryngeal cancer and 14.1 for lung cancer among heavy smokers and heavy alcohol drinkers. This study provides epidemiologic evidence from Turkey that smoking and alcohol use are associated with risks of cancers of the larynx and lung.

Background It is widely accepted that the development of atherosclerosis starts at an early age. However, there are very few studies evaluating the prevalence of the common clinical and behavioral cardiovascular disease (CVD) risk factors among children, especially in developing countries. The aim of the present cross-sectional survey was to evaluate the distribution of blood lipid profile and various behavioral (i.e. dietary habits, physical activity status) factors related to CVD risk and its relationships to paternal (PEL) and maternal educational level (MEL) among primary schoolchildren in Turkey. Methods In three major metropolises in Turkey (Istanbul, Ankara and Izmir), a random sample of 1044 children aged 12 and 13 years old was examined. ANOVA was applied to evaluate the tested hypothesis, after correcting for multiple comparisons (Tukey correction). Results After controlling for energy and fat intake, physical activity status and Body Mass Index (BMI), it was found that mostly PEL had a significant positive effect for most of the subgroups examined (Lower vs. Higher and Medium vs. Higher) on TC and HDL-cholesterol and a negative effect on TC/HDL ratio for both genders. Furthermore, both boys and girls with higher PEL and MEL were found to have higher energy intake derived from fat and protein than their counterparts with Medium and Lower PEL and MEL, while the opposite was observed for the percentage of energy derived from carbohydrates. Conclusions Our study provides indications for a possible association between an adverse lipid profile, certain dietary patterns and Higher PEL and MEL among schoolchildren in Turkey. These findings underline the possible role of social status, indicated by the degree of education of both parents, in developing certain health behaviors and health indices among Turkish children and provide some guidance for Public Health Policy.

To characterize the methicillin-resistant Staphylococcus aureus (MRSA) clones present in Istanbul, 102 MRSA isolates collected during a 5-year period at the Istanbul Medical Faculty Hospital were characterized using microarray analysis and phenotypic resistance profiles. Resistance to methicillin was detected with a cefoxitin disk diffusion assay and confirmed with a MRSA-agar and MRSA detection kit. Antimicrobial susceptibility testing was performed by a disk diffusion assay and interpreted according to the 2012 guidelines of the Antibiogram Committee of the French Society for Microbiology. Decreased susceptibility to glycopeptides was confirmed using the population analysis profile-area under the curve (PAP-AUC) method. The presence of the mecA gene was detected by polymerase chain reaction. Bacterial DNA was extracted according to the manufacturer's recommended protocol using commercial extraction kits. Strains were extensively characterized using the DNA microarray. Isolates were grouped into six clonal complexes. The most frequently detected clone was the Vienna/Hungarian/Brazilian clone (ST239-MRSA-III), which accounted for 53.9% of the isolates. These isolates were resistant to multiple antibiotics, particularly penicillin, tetracycline, rifampicin, kanamycin, tobramycin, gentamicin, levofloxacin, erythromycin, lincomycin and fosfomycin. Furthermore, three isolates were detected by population analysis profile as heterogeneous vancomycin-intermediate S. aureus (hVISA). The UK-EMRSA-15 clone (ST22-MRSA-IV PVL negative) was detected in 9.8% of the isolates and was mainly susceptible to all anti-staphylococcal antibiotics. Seven isolates (6.9%) were positive for PVL genes and were assigned to the CC80-MRSA-IV clone (European CA-MRSA clone, three isolates), ST8-MRSA-IV clone (USA300 clone, two isolates, one ACME-positive) or ST22-MRSA-IV clone ("Regensburg EMRSA" clone, two isolates). All other clones were detected in one to six isolates and corresponded to well-known clones (e.g., Pediatric clone, Dublin EMRSA clone, WA MRSA-54/63, WA MRSA-1/57). This work highlighted both the high prevalence of ST239-MRSA-III clone and the large diversity of the other MRSA clones detected in a university hospital in Istanbul.

2017-04-01

This is the first study to assess fungal diversity and mycotoxigenic fungi in open recirculating cooling-tower (CT) water systems (biofilm and water phase). The production capability of mycotoxin from fungal isolates was also examined. The mean fungal count in 21 different water and biofilm samples was determined as 234 CFU/100 mL and 4 CFU/cm 2 . A total of 32 species were identified by internal transcribed spacer (ITS) sequencing. The most common isolated fungi belonged to the genera Aspergillus and Penicillium, of which the most prevalent fungi were Aspergillus versicolor, Aspergillus niger, and Penicillium dipodomyicola. From 42% of the surveyed CTs, aflatoxigenic A. flavus isolates were identified. The detection of opportunistic pathogens and/or allergen species suggests that open recirculating CTs are a possible source of fungal infection for both the public and for occupational workers via the inhalation of aerosols and/or skin contact.

To evaluate the perspective of private hospitals regarding experience innovation. The qualification-type study was conducted in Istanbul, Turkey, in February 2015, and comprised 17 hospitals where patients and employees were interviewed using a semi-structured consultation guide. The employees were examined regarding the meaning of innovation, awareness of experience innovation and its measurement. The patients were asked about the reason for choosing a hospital, the actual reason for arrival at the hospital and the impressions while leaving the hospital. Based on the obtained answers, experience innovation was examined. Of the 87 subjects interviewed, 51(59%) were patients and 36(41%) were hospital employees. Overall, there were 61(70%) women and 26(30%) men in the age range of 21-75 years. It was observed that the tendencies of hospitals for innovation activities were high, but they confused it with novelty. Investments made without taking experience innovation into account do not convert into targeted results.

This is a descriptive study conducted in 2009 at Haseki Training and Research Hospital, Istanbul, Turkey. Hundred and twenty-six patients with subclinical hypothyroidism and 58 age and sex matched individuals were recruited. Simple spirometry tests were performed, and pulmonary diffusion capacity (DLco) and muscle strength were measured. ScH patients showed a significant reduciton of the following pulmonary function tests (% predicted value) as compared with control subjects: FVC, FEV1, FEV1%, FEF25-75, FEF25-75%, DLco, DLco/VA, Pimax, Pimax% and Pemax%. These data indicate that pulmonary functions are effected in subclinical hypothyrodism. Therefore patients with or who are at high risk of having subclinical hypothyroidism, should be subjected to evaluation of pulmonary functions with simple spirometry.

The life of Rudolf Nissen: advancing surgery through science and principle.

Rudolf Nissen (1896-1981) was a surgeon whose career began in Germany during the first third of the 20th century, a period of rapid progress in biomedical technology, during which neurosurgery, anesthesiology, and other specialties emerged. A protégé and later close colleague of thoracic surgery pioneer Ferdinand Sauerbruch (1875-1951), Nissen resigned from the Berlin Charité Clinic and left Germany in 1933, in response to the rise of Nazi fascism. Throughout his subsequent career in Istanbul, Turkey, the American cities of Boston and New York, and finally Basel, Switzerland, Nissen developed innovative surgical techniques, advocated for patient-centered medical education, and promoted surgical subspecialization. A lifelong proponent of clear scientific writing, Nissen expressed, in extensively published work, his philosophy that progress in surgery depends critically on rigorously applying the scientific method, upholding professional integrity, and respecting human dignity.

ARBO-ZOONET is an international network financed by the European Commission's seventh framework program. The major goal of this initiative is capacity building for the control of emerging viral vector-borne zoonotic diseases, with a clear focus on West Nile virus, Rift Valley fever virus, and Crimean-Congo hemorrhagic fever virus. To evaluate the status quo of control measures against these viruses, an ARBO-ZOONET meeting was held in Istanbul, Turkey, from 19 to 20 November 2009. The symposium consisted of three themes: (1) vaccines: new and existing ones; (2) antivirals: existing and new developments; and (3) antivector vaccines. In addition, a satellite workshop was held on epidemiology and diagnosis. The meeting brought together foremost international experts on the subjects from both within and without the ARBO-ZOONET consortium. This report highlights selected results from these presentations and major conclusions that emanated from the discussions held.

In Islamic religion, daytime fasting during the month called Ramadan is an annual practice. In this study, we aimed to investigate the effect of Ramadan fasting and maternal hypoalbuminaemia on neonatal growth parameters. A prospective case-control study was conducted in Diyarbakir and Istanbul, Turkey. The sample size of fasting group was 168 and that of non-fasting group was 170. Demographic characteristics, obstetrics ultrasonographic findings and laboratory parameters of the participants were recorded. Neonatal anthropometric parameters and placental weight were noted. The mean placental weight was significantly higher in the fasting group (p = 0.037). Also, in the fasting group, pregnant women with hypoalbuminaemia had significantly higher placental weight (p = 0.009). In conclusion, the mean placental weight in the fasting group was significantly higher. Also a significant correlation between placental weight and maternal serum albumin level was observed in the fasting group.

Seismic isolation is an effective design strategy to mitigate the seismic hazard wherein the structure and its contents are protected from the damaging effects of an earthquake. This paper presents the Hangar Project in Sabiha Goekcen Airport which is located in Istanbul, Turkey. Seismic isolation system where the isolation layer arranged at the top of the columns is selected. The seismic hazard analysis, superstructure design, isolator design and testing were based on the Uniform Building Code (1997) and met all requirements of the Turkish Earthquake Code (2007). The substructure which has the steel vertical trusses on facades and RC Hmore » shaped columns in the middle axis of the building was designed with an R factor limited to 2.0 in accordance with Turkish Earthquake Code. In order to verify the effectiveness of the isolation system, nonlinear static and dynamic analyses are performed. The analysis revealed that isolated building has lower base shear (approximately 1/4) against the non-isolated structure.« less

Financialisation in health care: An analysis of private equity fund investments in Turkey.

Eren Vural, Ipek

2017-08-01

The 2007-2008 global financial crisis revived interest in the impacts of financial markets and actors on our social and economic life. Nevertheless, research on health care financialisation remains scant. This article presents findings from research on one modality of financial investments in health care: global private equity funds' investments in private hospitals. Adopting a political economy approach, it analyses the drivers and impacts of the upsurge of global private equity investments in the Turkish private hospital sector amid the global financial crisis. The analysis derives from review of research and archival literature, as well as six in-depth interviews held with owners/executive board directors/general managers of the largest private hospital chains in Turkey and the general partners of their PE investors. The interviewing process took place between January and November 2016. All interviews were conducted by the author in Istanbul. The findings point to a mutually reinforcing relationship between neoliberal policies and financialisation processes in health care. The article shows that neoliberal healthcare reforms, introduced under consecutive Justice and Development Party (JDP) governments in Turkey, have been important precursors of private equity investments in healthcare services. These private equity investments, in turn, intensified and broadened the process of marketisation in health care services. Four impacts are identified, through which private equity investments hasten the marketisation of health care services. These relate to the impacts of private equity investments on a) advancing the process of chain formation by large hospital groups, b) spreading financial imperatives into the operations of private hospitals c) fostering internationalisation of capital, and d) augmenting inequities in access to health care services and standards.

Numerous studies in youth and adults suggest strong association between substance use disorders and non-suicidal self-injury (NSSI) and suicidal behaviors. There is paucity of studies exploring the association of substance use with history of suicide attempts (HSA) and NSSI in children and adolescents in Turkey. We aimed to examine the prevalence of NSSI and HSA and their relationship with substance use and family characteristics among youth seeking treatment for substance use in Turkey. Participants were children and adolescents who were admitted to the Bakirkoy Trainee and Research Hospital for Psychiatric and Neurologic Disorders in Istanbul between January 2011 and December 2013. Two thousand five hundred eighteen participants were included. Questionnaires were applied to all patients. The association of NSSI and HSA with substance use, family characteristics, and subject characteristics were analyzed. The prevalence of NSSI and HSA behaviors among substance using youth in our sample were 52% and 21% respectively. Cannabis and cocaine use was found to be a significant risk factor for HSA, and polysubstance use was associated with both NSSI and HSA. Parental separation/divorce, parental mental disorders, alcohol and drug use, and crime were the risk factors for HSA. A positive history of physical and sexual abuse increased the risk of HAS, and a history of neglect increased the risk of NSSI. Conclusions/importance: We suggest that results showing relationship between substance use and associated social features with NSSI and HSA may contribute to elaborating effective and targeted preventive and intervention programs for these high-risk youth groups in Turkey.

Worldwide increase in carbapenem resistance and transferable carbapenemases are significant challenges in treatment of Pseudomonas aeruginosa infections. In this study, investigation of carbapenemase production in carbapenem-resistant P. aeruginosa isolates recovered from clinical specimens in a tertiary hospital was aimed. A total of 84 carbapenem-resistant P. aeruginosa isolates were examined. "Carbapenem inactivation method" (CIM) was used for phenotypic detection of carbapenemase production. The existence of bla KPC , bla NDM , bla IMP , bla VIM , bla OXA-48 , and bla GES genes was investigated by polymerase chain reaction (PCR). Subtypes of the detected genes were identified by sequence analysis. Arbitrarily primed PCR (AP-PCR) was performed to evaluate the clonal relationship among the isolates. The presence of high-risk clones in carbapenemase producers was investigated by Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS). Three isolates (3.5%) were identified as carbapenemase producers by CIM tests, while PCR tests demonstrated three isolates carrying carbapenemase genes as well. bla VIM gene was found in two isolates and bla GES gene was found in one isolate. Sequence analysis demonstrated that the carbapenemases were VIM-1, VIM-2, and GES-5. AP-PCR yielded high clonal diversity among the isolates. According to MALDI-TOF MS analysis, none of the carbapenemase-producing strains belonged to the high-risk clones. In conclusion, the presence of VIM-1, VIM-2, and GES-5 type carbapenemases in P. aeruginosa isolates was demonstrated for the first time in our hospital, GES-5 being reported for the second time in Turkey. Our results will lead strategies for controlling the spread of carbapenemases and contribute to epidemiological data from Turkey.

Maintaining optimal adherence to antiretroviral therapy (ART) is essential for optimizing the management of HIV infection. The aim of this study is to explore ART adherence rates in Turkey. Included in this study were a total of 263 HIV-infected patients followed up by the ACTHIV-IST (ACTion against HIV in Istanbul) Study Group affiliated with four tertiary hospitals. The study population included patients 18 years of age or older who were on ART for over 12 months. Adherence was assessed by the medication possession ratio (MPR) calculated for each patient using data (a list of all drugs dispensed within the previous year for that patient) obtained from pharmacy medication records. In addition, patients completed a self-report questionnaire addressing missed doses and the AIDS Clinical Trials Group (ACTG) adherence questionnaire. The study was reviewed and approved by the Ethics Committee of Cerrahpasa Medical Faculty. Patient ages ranged from 19 to 71 years. Two hundred and thirty-one patients were male (88%). Two hundred and twenty-four patients (85%) had optimal adherence (MPR ≥95%). During the course of ART, 236 patients (90%) reported no missed doses in the past 4 days of their treatment, whereas 206 patients (78%) reported no missed doses in the past month. Simply forgetting was the most common reason for nonadherence. MPR was associated with virologic rebound. Major factors affecting adherence were being female, taking antituberculosis drugs, having an opportunistic infection, being able to take all or most of the medication as directed, and being aware of the need to take medication exactly as instructed to prevent the development of drug resistance. Adherence to ART measured by MPR and self-report surveys is relatively high in Turkey when compared with other countries, which probably led to high ART success rates.

Stress is commonly encountered among cancer patients and may be a challenge affecting immune system resistance. Social support may contribute positively to the health of cancer patients, playing a role in coping with stress. The aim of this study was to determine whether ways of coping are related to social support given to women with gynecologic cancer. The study was performed as a cross-sectional design in a university hospital in Istanbul, Turkey, with 221 women with gynecologic cancer; the data were collected via 3 questionnaires, the first with sociodemographic and clinical features, the second with multidimensional scale of perceived social support, and the third with the scale of ways of coping with stress. Women with gynecologic cancer who were employed and declared their incomes as balanced and reported more years of education were more likely to perceive higher social support and to use the ineffective coping ways with stress at a lower rate (P < .05) than other participants. Based on correlational analysis, effective coping ways with stress increase as perceived social support from family, friends, significant other, and total increases (P < .05). Social support from family members is the mainstay of coping with stress by women with gynecologic cancer. Nurses are indispensable in increasing social support required by women with gynecologic cancer. Well-trained clinical nurses via in-service programs should be experienced and aware of women diagnosed with gynecologic cancer in need of social support during hospital visits and provide necessary guidance.

The aim of this study was to compare the impact of case-based learning (CBL) and lecture-based learning (LBL) on fourth-year dental students' clinical decision making by using the Structure of Observed Learning Outcome (SOLO) taxonomy. Participants in the study were fourth-year dental students (n=55) in academic year 2012-13 taught in a large-group LBL context and fourth-year dental students (n=54) in academic year 2013-14 taught with the CBL methodology; both took place in the oral diseases course at Yeditepe University Faculty of Dentistry, Istanbul, Turkey. All eligible students participated, for a 100 percent response rate. A real case was presented to the students in both groups to assess their clinical decision making on the topic of oral diseases. Their performance was evaluated with the SOLO taxonomy. Student t-test was used for statistical evaluation, and significance was set at the p<0.05 level. A statistically significant difference was found between the mean scores of the relational and extended abstract categories of the CBL and LBL groups (p<0.05). Students who were taught with CBL had higher scores at the top two levels of the SOLO taxonomy than students taught with LBL. These findings suggest that an integrated case-based curriculum may be effective in promoting students' deep learning and it holds promise for better integration of clinical cases likely to be encountered during independent practice.

Istanbul, being one of the highly populated metropolitan areas of the world, has been facing water scarcity since the past decade. Water transfer from Melen Watershed was considered as the most feasible option to supply water to Istanbul due to its high water potential and relatively less degraded water quality. This study consists of two parts. In the first part, water quality data covering 26 parameters from 5 monitoring stations were analyzed and assessed due to the requirements of the "Quality Required of Surface Water Intended for the Abstraction of Drinking Water" regulation. In the second part, a one-dimensional stream water quality model with simple water quality kinetics was developed. It formed a basic design for more advanced water quality models for the watershed. The reason for assessing the water quality data and developing a model was to provide information for decision making on preliminary actions to prevent any further deterioration of existing water quality. According to the water quality assessment at the water abstraction point, Melen River has relatively poor water quality with regard to NH(4)(+), BOD(5), faecal streptococcus, manganese and phenol parameters, and is unsuitable for drinking water abstraction in terms of COD, PO(4)(3-), total coliform, total suspended solids, mercury and total chromium parameters. The results derived from the model were found to be consistent with the water quality assessment. It also showed that relatively high inorganic nitrogen and phosphorus concentrations along the streams are related to diffuse nutrient loads that should be managed together with municipal and industrial wastewaters.

Western Turkey consists of a number of tectonic terranes joined together by a network of suture zones. The terranes originated as microcontinental plates that rifted away from the continental margins forming the northern and southern boundaries of the Tethyan sea. These micro-continents were united by a series of collisions beginning in the Late Triassic and ending in the Miocene, with the final closure of the Tethyan sea. The sedimentary cover of the microcontinents consists of Paleozoic and Mesozoic passive margin and rift basin sequences containing numerous potential source and reservoir intervals. Most of these sequences show affinities with Gondwanaland, withmore » the notable exception of the Istanbul nappe, which is strongly Laurasian in character. Forearc basin sequences were also deposited on the margins of the microcontinents during early Tertiary plate convergence. Ensuing continental collisions resulted in compressional deformation of sedimentary cover sequences. The intensity of deformation ranged from basin inversion producing numerous potential hydrocarbon traps, to large-scale overthrusting. Following continental suturing, continued compression in eastern Turkey has been accommodated since the Miocene by westward escape of continental lithosphere between the North and South Anatolian transform faults. Neotectonic pull-apart basins formed in response to these movements, accumulating large thicknesses of Miocene-Pliocene carbonates and clastic sediments. Potential reservoirs in the Neotectonic basins may be sourced either in situ or from underlying Paleozoic and Mesozoic source rocks that remain within the hydrocarbon generating window today.« less

The most active fault system of Turkey is North Anatolian Fault Zone and caused two large earthquakes in 1999. These two earthquakes affected the eastern Marmara region destructively. Unbroken part of the North Anatolian Fault Zone crosses north of Armutlu Peninsula on east-west direction. This branch has been also located quite close to Istanbul known as a megacity with its high population, economic and social aspects. A new cluster of microseismic activity occurred in the direct vicinity southeastern of the Yalova Termal area. Activity started on August 2, 2014 with a series of micro events, and then on August 3, 2014 a local magnitude is 4.1 event occurred, more than 1000 in the followed until August 31, 2014. Thus we call this tentatively a swarm-like activity. Therefore, investigation of the micro-earthquake activity of the Armutlu Peninsula has become important to understand the relationship between the occurrence of micro-earthquakes and the tectonic structure of the region. For these reasons, Armutlu Network (ARNET), installed end of 2005 and equipped with currently 27 active seismic stations operating by Kocaeli University Earth and Space Sciences Research Center (ESSRC) and Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum (GFZ), is a very dense network tool able to record even micro-earthquakes in this region. In the 30 days period of August 02 to 31, 2014 Kandilli Observatory and Earthquake Research Institute (KOERI) announced 120 local earthquakes ranging magnitudes between 0.7 and 4.1, but ARNET provided more than 1000 earthquakes for analyzes at the same time period. In this study, earthquakes of the swarm area and vicinity regions determined by ARNET were investigated. The focal mechanism of the August 03, 2014 22:22:42 (GMT) earthquake with local magnitude (Ml) 4.0 is obtained by the moment tensor solution. According to the solution, it discriminates a normal faulting with dextral component. The obtained focal mechanism solution is conformable with the features of local faults in the region. The spatial vicinity of the earthquake swarm and the Yalova geothermal area may suggest a physical link between the ongoing exploitation of the reservoir and the earthquake activity.

ABSTRACT Pontides constitute an E-W trending orogenic mountain belt that extends about 1100 km along the northern side of Turkey from the immediate east of Istanbul to the Georgian border at the east. Tectono-stratigraphically, the Pontides are divided into three different parts: Eastern, Central, and Western Pontides. The Eastern Pontides, including the studied area, comprise an area of 500 km in length and 100 km in width, extending along the southeast coast of the Black Sea from the Kizilirmak and Yesilirmak Rivers in the vicinity of Samsun to the Little Caucasus. This area is bordered by the Eastern Black Sea basin to the north and the Ankara-Erzincan Neotethyan suture zone to the south. The Late Jurassic-Early Cretaceous platform carbonates are widely exposed in E-W direction in the Eastern Pontides (NE Turkey). The Platform carbonates shows varying lithofacies changing from supratidal to platform margin reef laterally and vertically, and was buried until the end of Late Cretaceous. The studied Ayralaksa Yayla (Trabzon, NE Turkey) area comprises one of the best typical exposures of formation in northern zone of Eastern Pontides. In this area, the lower parts of the formation are pervasively dolomitized by fabric-destructive and fabric-preserving replacement dolomite which are Ca-rich and nonstoichiometric (Ca56-66Mg34-44). Replacement dolomites (Rd) are represented by D18O values of -19.0 to -4.2 (VPDB), D13C values of 4.4 to 2.1 \\permil (VPDB) and 87Sr/86Sr ratios of 0.70889 to 0.70636. Petrographic and geochemical data indicate that Rd dolomites are formed prior to compaction at shallow-moderate burial depths from Late Jurassic-Early Cretaceous seawater and/or partly modified seawater as a result of water/rock interaction and they were recrystallized at elevated temperatures during subsequent burial. In the subsequent diagenetic process during the Late Cretaceous when the region became a magmatic arc, as a result of interaction with Early Jurassic volcanic rocks of basic composition, Rd dolomites were recrystallized by hydrothermal fluids of marine origin. Key words: Dolomitization; Geochemistry; Seawater origin; Recrystallization; Late Jurassic-Early Cretaceous, Platform carbonates; Berdiga Formation; Eastern Pontides, NE Turkey.

Obituary: Hakki Ogelman (1940-2011)

Orio, Marina

2011-12-01

Hakki Boran Ögelman died in Austin, Texas, on September 4, 2011, after battling esophageal cancer for several months. Hakki was born in Ankara, Turkey, on July 8, 1940, and was the son of Salehettin Ögelman, a lawyer, and Vedya Özlem Ögelman, a schoolteacher. He had a sister, older by three years, the late Esen Yerliçi. Soon after his birth, the family moved to Istanbul, where Hakki attended the Robert College from sixth grade and obtained an international baccalaureate at age 17. In the same year, he moved to the United States to further his education at DePaw University in Indiana, where he obtained a Bachelor's Degree in three years and developed a strong passion for physics. He was accepted as a graduate student in physics at Cornell University, where he was fortunate to have such professors as Hans Bethe and Ed Salpeter, among others. Hakki's advisor, Kenneth Greisen, had worked on the Manhattan Project and was a leading expert in the study of charged particles from space and gamma rays from astronomical sources. For his Ph.D., Hakki flew a balloon experiment to measure gamma rays at the highest energy, deriving from the radioactive decay of elementary particles from space. Hakki received his Ph.D. from Cornell in February of 1966. After a postdoctoral year working on gamma ray astrophysics at the University of Sydney in Australia, Hakki accepted a fellowship at NASA's Goddard Space Flight Center where he became an expert on pulsars and wrote a series of articles published by Nature on astronomical sources of gamma rays. At age 30, Hakki declined the offer of a civil service position at NASA and left for Turkey, feeling he wanted to give back to his home country, which had given him a strong education and instilled in him core values. After a period in the military as an officer, he was offered a position at the Middle East Technical University (METU) of Ankara, an English speaking university. After becoming a full professor at METU and spending a sabbatical year back at Goddard, Hakki took leave from Ankara to help the development of a university in the rural area of Adana and became the Dean of Basic Sciences at Çukurova University. He established a group working on exploitation techniques of solar energy and planned for himself and his wife a solar house that was built on campus. Hakki was a member of the Turkish Academy of Sciences, served as a member of the Executive Science Board for the Scientific and Technical Research Council of Turkey from 1976-1984, and represented Turkey on international science councils and co-operations. Turkey during those years was in turmoil, first apparently on the brink of a civil war and later governed by a strict military regime. Upsetting personal experiences convinced Hakki that Turkey had become too difficult for a free intellectual person, so he took a prolonged sabbatical at the Max Planck Institute for Extraterrestrial Physics in Garching near Munich, where he had already spent several summers and kept in touch with an international and vibrant community of scientists working on high-energy astrophysics. What started as a sabbatical stretched into almost 8 years. From gamma rays he moved to lower energies, X-rays, and made several interesting discoveries first with EXOSAT, then with ROSAT, the second imaging telescope in X-rays. Hakki was broadly educated across many areas of physics, astronomy and science in general. He was very curious and an avid reader of science and non-science books and articles. Such broad horizons helped him think "outside the box." He was the first to observe novae as accreting and exploding white dwarfs in binary systems in X-rays, thereby observing the "naked white dwarf" to obtain clues on its mass, chemical composition and possible evolutionary path toward a supernova Ia explosion. Hakki's work on cooling neutron stars, pulsars and their nebulae (his main interest) was always innovative. One difficult riddle he hoped to solve was the relationship between the mass and radius of a neutron star in order to infer the equation of state of neutron stars and whether they contain exotic particles. He was particularly interested in the glitches of neutron stars (sudden small increases in the rotation speed) because these may be caused by transitions of vortices in the superfluid core of the star. Turkey recognized Hakki as an outstanding scientist, and he was awarded the Sedat Simavi Prize in 1988 and the Turkish Scientific and Technical Research Council Prize in 1991. Eventually, Hakki returned to the U.S. where he felt that scientific life was most lively and interesting. He accepted a position as professor of physics at the University of Wisconsin in Madison at the beginning of 1991. Working with ROSAT, he made new discoveries related to neutron stars and novae. He mentored five successful graduate students and a post-doctoral associate, worked with countless collaborators, and was loved by his students in Wisconsin. He bought a house on Lake Monona in Madison because "being on water was important to him and reminded him of the Bosphorus." He visited Turkey for a long time every summer, worked with students and collaborators there, and was instrumental in establishing the Turkish National Observatory. In 1996, while he was at the peak of his career and his third son was just a year and a half old, Hakki's life was disrupted by a massive stroke. He became physically handicapped and had to slow his pace somewhat. He was able to go back to teaching and still carried on independent and original research, but he had to take time to rest after each activity. He taught at the University of Wisconsin until March of 2011, even after heart surgery a year earlier. Eventually, an aggressive form of cancer caught up with his energy and love of science and life. Hakki had been married three times, each marriage lasting for more than 10 years. He is survived by three sons and a daughter-in-law, Kenan Ögelman of Austin, Texas, Nedim and Laura Ögelman of Alexandria, Virginia, and Roberto Ögelman of Madison, Wisconsin, and two grandsons, Anders and Soren Ögelman, of Alexandria, Virginia. His family, friends and colleagues will miss Hakki's inquisitive spirit.

In this article, our aim was to summarise students' research over 15 years at Istanbul University Faculty of Dentistry and to evaluate both the research activities from the students' perspectives and the effect of this activity on their undergraduate and postgraduate success. In 1992, dental students formed 'a Student Research Club' (SRC), which new students attend voluntarily and carry out a scientific project out with the normal curriculum every year. In total, 409 different students have presented 193 research projects at these meetings over 15 years. Seventy-four of these students were from other universities and presented 37 projects. In this research, a questionnaire containing 20 items was administered to 93 students who were the members of SRC to learn their own perception of the development of their academic and research skills and the broader impact of the club on their career. It was evaluated using Likert scale (ranged from strongly disagree to strongly agree). Student feedback was very positive and over three quarters (81%) of answers ranged between 'agree' and 'strongly agree'. When the cumulative grade point average (CGPA) of the 88 SRC members in the last 6 years (2003/2004 to 2008/2009) was evaluated as the school success rate, significant difference was found between the grades obtained by members and non-members (P<0.001). There was also significant difference between the CGPA of 25 members of SRC who were randomly chosen, before and after membership to the club (P<0.001). While the 141 members of SRC applied to postgraduate education to Istanbul University Faculty of Dentistry over the last 5 years, 74 of them accepted for PhD (52.6%). There is a statistically significant difference between the member and non-member groups (P<0.001). In addition, of the 58 teaching assistants who stayed in academic life after postgraduate studies at Istanbul University Faculty of Dentistry, 16 of them had been a member of the SRC (31%). However, no statistical difference was found between members of SRC and non-members. These data showed that although the students had an intensive programme in the school, they were able to carry out this voluntary activity successfully and this activity contributed to their educational process. Students also believe that participation of them to this activity effects positively on both personal development and academic success. © 2011 John Wiley & Sons A/S.

OBJECTIVES: The aim of this study is to identify demographic, clinical and survival features of childhood central nervous system (CNS) tumors admitted to Istanbul University, Oncology Institute, Pediatric Hematology-Oncology in 22 years. METHODS: Charts of patients <19 years admitted were evaluated retrospectively. (Istanbul University Cerrahpasa Medical Faculty Clinical Trials, Ethics Committee no. 83045809-3507). RESULTS: CNS tumors (n = 494) comprised 20,5 % of the 2413 children with cancer, diagnosed between 1990-2012. Male/female:1,25. Median age was 6,5 years (0.13-18yrs). 51 patients had NF1, 4 had tuberosclerosis. Distrubution according to histopathology/diagnosis was as follows: 35 % (n = 173) Medulloblastoma and other embryonal tumors, 17% (n = 84) astrocytoma other than optic gliomas, 16,5% (n = 82) ependymoma and choroid plexus tumors, 14% (n = 69) optic glioma, and 12,8% (n = 63) diffuse pontine gliomas. 5-yrs and 10-yrs overall survival (OS) in the whole group were 61% and 55,4% respectively. 29,6 % of the patients had metastasis in the CSF and/or the spinal axis and/or gross residual tumor, these had 5-yrs and 10-yrs OS of 36,5% and 27,2 %, whereas the rest had 5-yrs and 10-yrs OS are 73% and 68,9% (p < 0,001). Medulloblastoma and other embryonal tumors had 5-yrs and 10-yrs OS 58,4% and 57,5% . Ependymoma and choroid plexus carcinomas had 5-yrs and 10-yrs OS of 48,4% and 31,4%. Low grade and high grade astrocytomas had 10-yrs OS of 95 % and 40% respectively (p < 0,001). Second tumors were diagnosed in two medulloblastoma patients, one malignant nerve sheath tumor at 9 years, a case with concurrent high glade glioma and mediastinal lymphoblastic lymphoma at 3,5 years. CONCLUSIONS: The most common solid tumor in our cohort, similar to developed countries, was CNS tumors. Embryonal tumors comprised the majority of the CNS tumors treated in our institution. 5 year survival was 61 %. These children should be followed up for late effects including second tumors.

In recent years several strong motion networks have been established in Istanbul with a preparation purpose for future probable earthquake. This study addresses the introduction of current seismic networks and presentation of some recent results recorded in these networks. Istanbul Earthquake Early Warning System Istanbul Earthquake Early Warning System has ten strong motion stations which were installed as close as possible to Marmara Sea main fault zone. Continuous on-line data from these stations via digital radio modem provide early warning for potentially disastrous earthquakes. Considering the complexity of fault rupture and the short fault distances involved, a simple and robust Early Warning algorithm, based on the exceedance of specified threshold time domain amplitude levels is implemented. The current algorithm compares the band-pass filtered accelerations and the cumulative absolute velocity (CAV) with specified threshold levels. The bracketed CAV window values that will be put into practice are accepted as to be 0.20, 0.40 and 0.70 m/s for three alarm levels, respectively. Istanbul Earthquake Rapid Response System Istanbul Earthquake Rapid Response System has one hundred 18 bit-resolution strong motion accelerometers which were placed in quasi-free field locations (basement of small buildings) in the populated areas of the city, within an area of approximately 50x30km, to constitute a network that will enable early damage assessment and rapid response information after a damaging earthquake. Early response information is achieved through fast acquisition and analysis of processed data obtained from the network. The stations are routinely interrogated on regular basis by the main data center. After triggered by an earthquake, each station processes the streaming strong motion data to yield the spectral accelerations at specific periods and sends these parameters in the form of SMS messages at every 20s directly to the main data center through a designated GSM network and through a microwave system. A shake map and damage distribution map (using aggregate building inventories and fragility curves) will then be automatically generated using the algorithm developed for this purpose. Loss assessment studies are complemented by a large citywide digital database on the topography, geology, soil conditions, building, infrastructure and lifeline inventory. The shake and damage maps will be conveyed to the governor's and mayor's offices and army headquarters within 3 minutes using radio modem and GPRS communication. Self Organizing Seismic Early Warning Information Network (SOSEWIN) in Atakoy District SOSEWIN sensors were developed by GFZ and Humbold University as part of SAFER project and EDIM project, and with cooperation of KOERI, the sensors were installed in Atakoy district of Istanbul city with Early Warning purpose. The main features of the SOSEWIN system are each sensing unit is comprised of low-cost components, undertakes its own seismological data processing, analysis and archiving, and its self-organizing capability with wireless mesh network communication. Seismic Network in Important Structures Some of the critical structures located in Istanbul city such as Fatih Sultan Mehmet Suspension Bridge which is connecting Asian and European sides of the city, Hagia Sophia Museum and Suleymaniye Mosque which are historical structures with an age of over 1000 years and 450 years respectively, . Kanyon Tower&Mall, Trakya Elektrik (formerly ENRON) and Isbank Tower (ISKULE) are monitorized to observe their seismic behaviors.

Spatial analysis and facility characteristics of outdoor recreational areas in Istanbul.

PubMed

Kara, Fatih; Demirci, Ali

2010-05-01

This article reports the results of a study that explored whether outdoor recreational areas are sufficient in Istanbul in terms of their surface area and facility characteristics. All the municipalities in 32 subprovinces of Istanbul were sent a survey in 2007 and asked to prepare a list of their outdoor recreational areas including their names, addresses, size, and facilities. All the data collected from the municipalities were used to create a GIS-based inventory by using GIS and remote sensing. As the study revealed, the outdoor recreational areas in Istanbul are far behind meeting the recreational needs of the residents in terms of area per person and facility characteristics. There are 2,470 areas which were dedicated to outdoor recreational activities in Istanbul. Total surface area of all these outdoor recreational areas is 19,2 sq kilometers; this means 1.52 m(2) recreational area per person in the city. This value is very low when compared to that of many cities in Europe and USA. As the study also revealed, the majority of outdoor recreational areas in Istanbul are poor in facility. Majority of the existing outdoor recreational areas are small and do not provide the public with many opportunities to engage in different outdoor activities. A more sustainable and efficient recreational plan is needed in Istanbul to meet the various recreational needs of its residents.

Population issues surface at human settlements conference.

PubMed

1996-01-01

This news brief focuses on the debate about population issues at the UN Conference on Human Settlements, held in Istanbul, Turkey, in June 1996. The Istanbul Declaration on Human Settlements was adopted by world leaders at the conference. Leaders were committed to programs to improve standards of living, the right of citizens to adequate housing, and the mobilization of new financial resources. Dr. Sadik, as Executive Director of the UN Population Fund, stressed that natural increase accounts for 60% of urban population growth. Mr. Boutros Boutros-Ghali, as UN Secretary General, stressed that over 50% of world population would live in urban centers by the year 2000, and almost 75% might do so by 2025. He indicated that all nations are interrelated; the poor and refugees from political conflict from one country travel to safer and richer countries. Dr. Sadik referred to the agreement at the 1994 International Conference on Population and Development (ICPD) on stabilizing world population in the shortest time possible. This would require meeting the needs of men and women for health, education, and the power of personal decision making. The most important item was the satisfaction of women's need for reproductive health information and services and women's power to use services. Dr. Sadik urged that women be given the right to hold and inherit property and to obtain credit. It was pointed out that the language of Habitat's plan of action on population and development issues was frequently bracketed; consequently, the plan suffered from a lack of consensus. The debate between countries would end, if the language were not bracketed. Dr. Sadik recommended family planning for developing sustainable and liveable cities.

Climate change effects on extreme flows of water supply area in Istanbul: utility of regional climate models and downscaling method.

PubMed

Kara, Fatih; Yucel, Ismail

2015-09-01

This study investigates the climate change impact on the changes of mean and extreme flows under current and future climate conditions in the Omerli Basin of Istanbul, Turkey. The 15 regional climate model output from the EU-ENSEMBLES project and a downscaling method based on local implications from geophysical variables were used for the comparative analyses. Automated calibration algorithm is used to optimize the parameters of Hydrologiska Byråns Vattenbalansavdel-ning (HBV) model for the study catchment using observed daily temperature and precipitation. The calibrated HBV model was implemented to simulate daily flows using precipitation and temperature data from climate models with and without downscaling method for reference (1960-1990) and scenario (2071-2100) periods. Flood indices were derived from daily flows, and their changes throughout the four seasons and year were evaluated by comparing their values derived from simulations corresponding to the current and future climate. All climate models strongly underestimate precipitation while downscaling improves their underestimation feature particularly for extreme events. Depending on precipitation input from climate models with and without downscaling the HBV also significantly underestimates daily mean and extreme flows through all seasons. However, this underestimation feature is importantly improved for all seasons especially for spring and winter through the use of downscaled inputs. Changes in extreme flows from reference to future increased for the winter and spring and decreased for the fall and summer seasons. These changes were more significant with downscaling inputs. With respect to current time, higher flow magnitudes for given return periods will be experienced in the future and hence, in the planning of the Omerli reservoir, the effective storage and water use should be sustained.

Discriminating between a creeping and a locked status of active faults is of central relevance to characterize potential rupture scenarios of future earthquakes and the associated seismic hazard for nearby population centres. In this respect, highly similar earthquakes that repeatedly activate the same patch of an active fault portion are an important diagnostic tool to identify and possibly even quantify the amount of fault creep. Here, we present a refined hypocentre catalogue for the Marmara region in northwestern Turkey, where a magnitude M up to 7.4 earthquake is expected in the near future. Based on waveform cross-correlation for selected spatial seismicity clusters, we identify two magnitude M ∼ 2.8 repeater pairs. These repeaters were identified as being indicative of fault creep based on the selection criteria applied to the waveforms. They are located below the western part of the Marmara section of the North Anatolian Fault Zone and are the largest reported repeaters for the larger Marmara region. While the eastern portion of the Marmara seismic gap has been identified to be locked, only sparse information on the deformation status has been reported for its western part. Our findings indicate that the western Marmara section deforms aseismically to a substantial extent, which reduces the probability for this region to host a nucleation point for the pending Marmara earthquake. This is of relevance, since a nucleation of the Marmara event in the west and subsequent eastward rupture propagation towards the Istanbul metropolitan region would result in a substantially higher seismic hazard and resulting risk than if the earthquake would nucleate in the east and thus propagate westward away from the population centre Istanbul.

Geochronology and sources of heavy metal pollution in sediments of Istanbul Strait (Bosporus) outlet area, SW Black Sea, Turkey.

Geochemical and sedimentological analyses and radionuclide ( 210 Pb and 137 Cs) dating of three cores from the Bosporus outlet area of the Black Sea, north of Istanbul, were conducted to assess the sources and history of heavy metal pollution. The sedimentary succession in the shelf core KD12-01 consists mainly of clay (49-80%) and silt (15-41%). Radionuclide dating of the core indicates that it consists of old sediments that are uncontaminated with heavy metals. In contrast, cores KD12-04 and KD12-07 recovered from -350 m and -304 mm in the upper slope area represent sediments consisting of silt and clay that were deposited since at least the last 120 years and 60 years, respectively. The latter core contains two mass-flow units represented by relatively old sedimentary material according to the low 210 Pb activity and relatively low heavy metal contents. The upper 40 and 48 cm of cores KD 12-04 and KD 12-07 represent sediments deposited since 1970s and 1980s that are significantly polluted with Cu, Ni, Zn, Mo, Pb and Cr, Cu, Co, Ni, Mo, Pb, Zn, respectively. However, high Pb and Cr concentrations with high TOC contents date back to early part of the 20th century in core KD 12-04. The geochemical data, together with the high 137 Cs concentrations of the contaminated sediments, strongly suggest that the pollution is mainly delivered to the western and north western Black Sea by the large European rivers, from there transported to the study area by the rim current, and deposited in the sediments under anoxic conditions.

To investigate perinatal factors that affect breastfeeding of newborns delivered at a baby-friendly public hospital in Turkey, including the time of the first physical examination by a pediatrician, the first union with their mothers, and the first breastfeeding time after delivery. The research was conducted from May 2nd through June 30th, 2011, in a baby-friendly public hospital in Istanbul. The sample consisted of 194 mothers and their full-term newborns. The data were collected via an observation form developed by the researchers. In analyzing the data, the average, standard deviation, minimum, maximum values, Chi-square, and percentages were used. The results revealed that the first physical examinations of the newborns were performed approximately 53.02±39min (range, 1-180 min) after birth. The newborns were given to their mothers approximately 69.75±41min (range, 3-190 min) after birth. Consequently, the first initiated breastfeeding took place approximately 78.58±44min following birth, and active sucking was initiated after approximately 85.90±54min. A large percentage of the newborns (64.4%) were not examined by a specialist pediatrician within half an hour of birth, and 74.7% were not united with their mothers within the same period. Also, the newborns who initiated breastfeeding within the first half hour had significantly earlier success with active sucking and required significantly less assistance to achieve successful breastfeeding. The newborns in our study met with their mothers late in the birth ward because examinations of the newborns were delayed. The newborns began initial sucking later, and this chain reaction negatively impacted the breastfeeding success of the newborns. Copyright © 2016 Elsevier Inc. All rights reserved.

Microseismicity at the North Anatolian Fault in the Sea of Marmara offshore Istanbul, NW Turkey

2009-01-01

The North Anatolian Fault Zone (NAFZ) below the Sea of Marmara forms a “seismic gap” where a major earthquake is expected to occur in the near future. This segment of the fault lies between the 1912 Ganos and 1999 İzmit ruptures and is the only NAFZ segment that has not ruptured since 1766. To monitor the microseismic activity at the main fault branch offshore of Istanbul below the Çınarcık Basin, a permanent seismic array (PIRES) was installed on the two outermost Prince Islands, Yassiada and Sivriada, at a few kilometers distance to the fault. In addition, a temporary network of ocean bottom seismometers was deployed throughout the Çınarcık Basin. Slowness vectors are determined combining waveform cross correlation and P wave polarization. We jointly invert azimuth and traveltime observations for hypocenter determination and apply a bootstrap resampling technique to quantify the location precision. We observe seismicity rates of 20 events per month for M < 2.5 along the basin. The spatial distribution of hypocenters suggests that the two major fault branches bounding the depocenter below the Çınarcık Basin merge to one single master fault below ∼17 km depth. On the basis of a cross-correlation technique we group closely spaced earthquakes and determine composite focal mechanisms implementing recordings of surrounding permanent land stations. Fault plane solutions have a predominant right-lateral strike-slip mechanism, indicating that normal faulting along this part of the NAFZ plays a minor role. Toward the west we observe increasing components of thrust faulting. This supports the model of NW trending, dextral strike-slip motion along the northern and main branch of the NAFZ below the eastern Sea of Marmara.

Objectives: To compare epithelial healing time following laser epithelial keratomileusis (LASEK) and photorefractive keratectomy (PRK) with anterior segment optic coherence tomography (AS-OCT). Methods: This prospective interventional case series study comprised 56 eyes of 28 patients that underwent laser refractive surgery in the Department of Ophthalmology, Medipol University Medical Faculty, Istanbul, Turkey, between March 2014 and May 2014. Each patient was randomized to have one eye operated on with PRK, and the other with LASEK. Patients were examined daily for 5 days, and epithelial healing time was assessed by using AS-OCT without removing therapeutic contact lens (TCL). Average discomfort scores were calculated from ratings obtained from questions regarding pain, photophobia, and lacrimation according to a scale of 0 (none) to 5. Results: The mean re-epithelialization time assessed with AS-OCT was 3.07±0.64 days in the PRK group, 3.55±0.54 days in the LASEK group, and the difference was statistically significant (p=0.03). Mean subjective discomfort score was 4.42±0.50 in the PRK eyes, and 2.85±0.44 in the LASEK eyes on the first exam day (p=0.001). The score obtained on the second (p=0.024), and third day (p=0.03) were also statistically significant. The fourth (p=0.069), and fifth days scores (p=0.1) showed no statistically significant difference between groups. Conclusion: The PRK showed a statistically significant shorter epithelial healing time, but had a statistically significant higher discomfort score until the postoperative fourth day compared with LASEK.

To compare the safety and efficacy of Ozil Intelligent Phaco torsional microcoaxial phacoemulsification surgeries performed with 12-degree and 22-degree bent tips using the Infiniti Vision System. Maltepe University School of Medicine Department of Ophthalmology, Istanbul, Turkey. Comparative case series. Eyes were assigned to 2.2 mm microcoaxial phacoemulsification using the torsional mode with a 22-degree bent tip (Group 1) or a 12-degree bent tip (Group 2). The primary outcome measures were ultrasound time (UST), cumulative dissipated energy (CDE), longitudinal and torsional ultrasound (US) amplitudes, mean surgical time, mean volume of balanced salt solution used, and surgical complications. Both groups included 45 eyes. The mean UST, CDE, longitudinal US amplitude, and torsional US amplitude were 65 seconds ± 27.23 (SD), 11.53 ± 6.99, 0.22 ± 0.26, and 42.86 ± 15.64, respectively, in Group 1 and 84 ± 45.04 seconds, 16.68 ± 10.66, 0.48 ± 0.68, and 46.27 ± 14.74, respectively, in Group 2. The mean UST, CDE, and longitudinal amplitudes were significantly lower in Group 1 (P=.003, P=.008, and P=.022, respectively). The mean volume of balanced salt solution was 73.33 ± 28.58 cc in Group 1 and 82.08 ± 26.21 cc in Group 2 (P=.134). Torsional phacoemulsification performed with 22-degree bent tips provided more effective lens removal than 12-degree bent tips, with a lower UST and CDE. Copyright © 2013 ASCRS and ESCRS.

2013-01-01

Background The aim of this study is to investigate the associations between migraine related disability and somatosensory amplification, depression, anxiety, and stress. Method Fifty-five migraine patients who applied to the outpatient unit of the Neurology Department of Acibadem University School of Medicine, Maslak Hospital in Istanbul, Turkey, and twenty-eight subjects without migraine were recruited for the study. The participants were asked to complete a sociodemographic form, Migraine Disability Assessment Scale (MIDAS), Depression Anxiety Stress Scale, Somatosensory Amplification Scale (SSAS). Results Somatosensory amplification scores were significantly higher in the migraineurs than in the control group (29.85+/−6.63 vs 26.07+/−7.1; p=0.027). Somatosensory amplification scores and depression scores were significantly higher in migraineurs with moderate and severe disability than in patients with minimal and mild disability (31.7+/−6.4 vs 27.71+/−5.49; p=0.01, 11.27+/−8.7 vs 7.38+/−8.11; p=0.04, respectively). A significant positive correlation was found between the frequency of migraine attacks for at least three consecutive months (MIDAS A scores) and the SSAS scores (r=0.363, p=0.007) in migraineurs. The MIDAS total scores were also significantly correlated with the DASS depression subcale scores (r=0.267, p=0.04), and the DASS stress subscale scores (r=0.268, p=0.05). Conclusion Psychological factors, and vulnerability to bodily sensations may incease the burden of migraine. We point out that the timely assessing of somatic amplification and the evaluation of mental status would help improve the quality of life of in migraineurs. PMID:23799958

Twice in the past 1000 years a sequence of large earthquakes has propagated from east to west along the North Anatolian fault (NAF) in Turkey towards Istanbul, with the final earthquake in the sequence destroying the city. This occurred most recently in 1509. The population of greater Istanbul is 20 million and the next large earthquake of the current sequence is considered imminent. The most likely location for a major earthquake on the NAF is considered the Marmara-Sea/Princes-Island segment south and southeast of Istanbul [Bohnhoff et al., 2013]. Insights into the nucleation and future behavior of this segment of the NAF are anticipated from measuring deformation near the fault, and in particular possible aseismic slip processes on the fault that may precede as well as accompany any future rupture. Aseismic slip processes near the western end of the Izmit rupture, near where it passes offshore beneath the Sea of Marmara near Izmit, has been successfully monitored using InSAR, GPS, and creepmeters. A 1mm amplitude, 24h creep event was recorded by our creepmeter near Izmit in 2015. These instruments and methods are of limited utility in monitoring the submarine portion of the NAF Data from numerous borehole strainmeters (BSM) along the San Andreas Fault, including those that were installed and maintained as part of the EarthScope Plate Boundary Observatory (PBO), demonstrate that the characteristics of creep propagation events with sub-cm slip amplitudes can be quantified for slip events at 10 km source-to-sensor distances. Such distances are comparable to those between the mainland and the submarine NAF, with some islands allowing installations within 3 km of the fault. In a collaborative program (GeoGONAF) between the National Science Foundation, GeoForschungsZentrum, Turkish Disaster and Emergency Management Authority, and the Kandilli Observatory, we installed an array of six PBO type BSM systems, which include strainmeters and seismometers, around the eastern end of the Marmara. The sensors are installed at depths of 100 m and record at a rate of 100Hz. During the installation phase (2014-16), the partially complete array successfully recorded seiches in the Sea of Marmara and a number of teleseismic events. The ESNK station, which is located to the west of Yalova is recording signals indicative of creep events.

To determine the relationship between healthy lifestyle behaviours of mothers and obesity in their pre-school children. The cross-sectional study was performed in a district of Istanbul, Turkey, between April and June 2011, and comprised children aged 4-6 years attending public pre-schools and their mothers.. Data was obtained using a questionnaire and Healthy Lifestyle Behaviours Scale-II. Number Cruncher Statistical System 2007 was used for statistical analysis. Of the 531 children in the study, 246(46.3%) were girls. Overall prevalence of overweight was 136(25.6%), obesity 77(14.5%)Overweight mothers were 126(23.7%), and obese mothers were 31(5.8%). The mothers of obese children obtained lower scores in the physical activity (p<0.05) and nutrition (p=0.001) subscales, and their total score was also lower (p<0.05).. Lifestyle behaviours of mothers, especially with respect to nutrition and physical activity, may influence obesity among preschool children. Strategies should be developed to improve the physical activity and eating habits of mothers.

Objective measurement of the job performance of nursing staff using valid and reliable instruments is important in the evaluation of healthcare quality. A current, valid, and reliable instrument that specifically measures the performance of nurses is required for this purpose. The aim of this study was to determine the validity and reliability of the Turkish version of the Job Performance Instrument. This study used a methodological design and a sample of 240 nurses working at different units in four hospitals in Istanbul, Turkey. A descriptive data form, the Job Performance Scale, and the Employee Performance Scale were used to collect data. Data were analyzed using IBM SPSS Statistics Version 21.0 and LISREL Version 8.51. On the basis of the data analysis, the instrument was revised. Some items were deleted, and subscales were combined. The Turkish version of the Job Performance Instrument was determined to be valid and reliable to measure the performance of nurses. The instrument is suitable for evaluating current nursing roles.

We investigate earthquakes with similar waveforms in order to characterize spatiotemporal microseismicity clusters within the North Anatolian fault zone (NAFZ) in northwest Turkey along the transition between the 1999 ??zmit rupture zone and the Marmara Sea seismic gap. Earthquakes within distinct activity clusters are relocated with cross-correlation derived relative travel times using the double difference method. The spatiotemporal distribution of micro earthquakes within individual clusters is resolved with relative location accuracy comparable to or better than the source size. High-precision relative hypocenters define the geometry of individual fault patches, permitting a better understanding of fault kinematics and their role in local-scale seismotectonics along the region of interest. Temporal seismic sequences observed in the eastern Sea of Marmara region suggest progressive failure of mostly nonoverlapping areas on adjacent fault patches and systematic migration of microearthquakes within clusters during the progressive failure of neighboring fault patches. The temporal distributions of magnitudes as well as the number of events follow swarmlike behavior rather than a mainshock/aftershock pattern.

ISS027-E-033889 (16 May 2011) --- Izmir Metropolitan Area, Izmir Province in Turkey is featured in this image photographed by an Expedition 27 crew member on the International Space Station. The metropolis of Izmir is located in the western Anatolia region of Turkey. It is the country’s third largest city in terms of population and the second largest port city (after Istanbul). The Izmir region has included urban areas for almost 3,500 years, and the ancient core of the metropolitan area was originally known as Smyrna. Due to its location on the Gulf of Izmir (lower left) with access to the Aegean Sea, Izmir (or Smyrna) has been an important Mediterranean Sea port for most of its history. This detailed photograph highlights the modern urban landscape of the Izmir metropolitan area. Today, the metropolitan area includes eleven districts, many of which were independent neighborhoods prior to agglomeration into “greater Izmir”. Densely built-up residential and commercial districts, characterized by gray to reddish gray rooftops occupy much of the central part of the image. Larger structures with bright white rooftops are indicative of commercial/industrial areas near the Izmir Port at left. Two large sport complexes, the Ataturk Stadium and Sirinyer Hippodrome (horse racing track) are clearly visible at upper left and right respectively. Numerous vegetated parks (green) are located throughout the area. In addition to being a major trade center, greater Izmir is a hub for regional tourism.

In 2008, we conducted a nonexperimental, cross-sectional, descriptive study in the surgical services department of a hospital in Istanbul, Turkey, with the aim of determining how much information was required by perioperative patients and their family members, the extent to which this information was provided, and the role that nurses play in this process. We included a total of 394 outpatients and inpatients and their family members (ie, 197 patients, 197 family members) and 30 nurses in the study. We collected the research data by using one questionnaire for patients, a second for family members of patients, and a third for nurses. We discovered that the patients and their family members wanted to be given more information about the surgical process than they had received. Patients wanted more information about the intraoperative period, whereas their family members wanted more information about the postoperative period. We also found that nurses were aware that they did not play an effective role in providing information to patients and their family members because of a lack of knowledge about what information they were responsible for providing and insufficient staffing. We concluded that nurses should know what education they are responsible for providing, put more effort into understanding patient and family member information needs, and plan a better means of providing information to meet those needs.

Severe combined immunodeficiency (SCID) is a neonatal emergency. As the T-cell receptor excision circles (TREC) test is not cost effective for neonatal screening of SCID in developing countries, this pilot study's objective aimed at identifying preliminary data to enable SCID identification in the general population. This observational study was performed in Bagcılar Training and Research Hospital, Istanbul, Turkey. Cord-blood complete blood count (CBC) was recorded in all neonates included in the study. Absolute lymphopenia was considered in cord-blood samples if the absolute lymphocyte count was less than 2500/mm 3 . A control blood count was performed 1-month later for cases with detected lymphopenia. A total of 2945 term neonates were included in the study. Absolute lymphopenia was found in nine (0.3%) neonates, while 2936 (99.7%) had an absolute lymphocytic count above 2.5 × 10 3 /mm 3 . The mean counts of red blood cells (RBC), hemoglobin (HGB), hematocrit (HCT), platelets (PLT), and monocytes in the lymphopenia group were not found to significantly differ from the non-lymphopenia group. However, there were significantly lower mean white blood cell (WBC), lymphocyte, and neutrophil counts between the groups (p < .05). Absolute lymphopenia detected using CBC analysis is a simple, easier, more non-invasive, and cheaper method than the TREC method for detection of SCID neonates, and this method may prove to be a useful alternative, especially in developing countries.

Wellbeing is one's evaluation and judgment of one's life. It consists of 3 dimensions: positive affectivity, negative affectivity, and life satisfaction. This study aimed to compare the subjective wellbeing and positive future expectations between working and nonworking adolescents. The study was designed as descriptive and comparative. The study sample consisted of 420 working and 482 nonworking adolescents (n = 902) aged 15 - 20 years, who were randomly recruited from two occupational education centers in Istanbul, Turkey and two high schools (formal educations) in the same district. Adolescent subjective wellbeing scale (ASWS) total mean (SD) scores for working adolescents and nonworking adolescents were 48.76 (9.50) and 49.72 (8.01), respectively. In addition, positive future expectations scale (PFES) total mean (SD) scores for working adolescents and nonworking adolescents were 18.71 (4.50) and 19.06 (3.49), respectively. In this study, no significant difference was found between the general wellbeing (scale total median score) scores of the working and nonworking adolescent groups (Z = 1.01, P = 0.315). However, significant differences were found in the family relations satisfaction (Z = 3.23, P = 0.002) and relations with significant others (Z = 2.85, P = 0.004) subscales of the ASWS. A positive relationship was found between adolescent subjective wellbeing and positive future expectations. It was found that nonworking adolescents scored higher on the dimensions of "family relations" and "relations with significant others" of subjective wellbeing compared to those dimensions in working adolescents.

A presumably spontaneous mutation has resulted in the formation of Hemoglobin (Hb) Istanbul in which glutamine is substituted for histidine in the proximal position of the β-chain (F8(92)). The anemia and other physiological effects that occur in the presence of Hb Istanbul were much ameliorated by splenectomy. Hb Istanbul is a relatively unstable molecule which produces a rather moderate case of “unstable hemoglobin hemolytic anemia.” In the determination of structure, a method of preferential cleavage of an aspartyl-proline bond at residues 99-100 of the β-chain was used.

We calculate the probability of strong shaking in Istanbul, an urban center of 10 million people, from the description of earthquakes on the North Anatolian fault system in the Marmara Sea during the past 500 years and test the resulting catalog against the frequency of damage in Istanbul during the preceding millennium, departing from current practice, we include the time-dependent effect of stress transferred by the 1999 moment magnitude M = 7.4 Izmit earthquake to faults nearer to Istanbul. We find a 62 ± 15% probability (one standard deviation) of strong shaking during the next 30 years and 32 ± 12% during the next decade.

Dr. Hulusi Behçet was born on February 20, 1889 in Istanbul. He graduated from Gülhane Military Medical Academy in 1910 and then he specialized in Dermatology and Venereal Diseases. He served in the Edirne Military Hospital between 1914-1918 and then went to Budapest and Berlin to improve his knowledge. In 1923, he started at the Istanbul Medical Faculty as an academic staff and with university reform in 1933, he was appointed as a professor to Department of Dermatology and Venereal Diseases and continued his career there until his death in 1948. Three patients whom he had consulted for years and who shared similar symptoms made him suspect a new disease and a viral etiology which may play a role in the appearance of this disease. After several discussions and publications, medical literature had accepted Behçet's Disease as a special entity. Dr. Behçet published a total of 196 articles, 53 of which were published in prestigious international journals.

Medical schools have a long history in Ottoman-Turkish medical education. At Ottoman medical schools (medreses), education has been given to students regularly. But because of social dogma and oppression of religion on the science of human anatomy they could not get a chance to improve for centuries. Traditionally, Ottoman-Turkish medical education was shaped under the influence of Galenos (129-200) and Avicenna (980-1037). These influences continued until the beginning of the 19th century. In this period, Avicenna's most famous medical book "Kanun-i fit-tip" was a main anatomy textbook in medical education of the eleventh century. Modernization of educational systems in the Ottoman Empire started during the reign of Sultan Selim the 3rd (1789-1807) and modern anatomy in Ottoman-Turkish Medicine has flourished following the Austrian physicians. Today's Department of Anatomy at Istanbul Medical School of the Istanbul University is a continuation of Galatasaray Medical School which was the first medical school achieving the western educational level.

The BS-MFC entered the Copernicus Marine Environment Monitoring Service (CMEMS, http://marine.copernicus.eu/) in October 2016, providing regular and systematic information about the ocean state in the Black Sea in operational mode. An expert team constitutes the BS-MFC Consortium: the Institute of Oceanology, Bulgarian Academy of Sciences (IO-BAS, Bulgaria) coordinates the service and the management in collaboration with Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC, Italy), Helmholtz-Zentrum Geesthacht - Institute of Coastal Research (HZG, Germany), the University of Liege (ULG, Belgium), the Sofia University "St. Kliment Ohridski (USOF, Bulgaria) and the Eurasia Earth Sciences Institute - Istanbul Technical University (ITU, Turkey). The system provides a complete data catalogue for the Black Sea ocean variables such as temperature, salinity, sea level, currents, biogeochemistry and waves through a technologically advanced and resilient service, which is fully interconnected with the other Centers in the Copernicus network. The high level BS-MFC architecture is based on 3 Production Units, for Physics, Biogeochemistry and Waves products respectively, a Dissemination/Archiving Unit for the delivery of the products and their archiving/accessibility, a Local Service Desk connected to the CMEMS Service Desk devoted to support all the operational activities, and backup units for all the main service components. Products consist of analysis/hindcast, 10-days forecast and reanalysis, describing the physical (currents, temperature, salinity, sea level, mixed layer depth and bottom temperature), the biogeochemical state and waves. To implement and improve the service, the BS-MFC has detailed an evolution plan, actually under implementation, devoted to establish, assess and improve the systems and their operational functionalities, providing some improvements from the scientific point of view concerning the modeling components (e.g., the fully aligned Physics, Biogeochemistry and Waves systems, the open boundary conditions at the Bosporus, the state-of-the-art core models and increased spatial resolution among the major actions) and high quality products, towards an optimal interface between the Mediterranean and the Black Seas. The contribution will present the main operational and research & development activities at the basis of the systems, given an overview on the future plans for improving the service for the delivery of new products.

A. Vallaury appears in the Ottoman society as an architect and an educator with his remarkable personality in the late XIX. century. In this essay two buildings designed by Vallaury, "Mekteb-i Tibbiye-i Sâhâne" and "Büyükada Greek Orphanage" are described. This study consists of three parts, Vallaury's life story, his works and contribution to the Ottoman architecture. Vallaury was born in Istanbul on April 2, 1850. His parents were of Levantin and French origin. He went to Paris for higher education and attended the School of Fine Arts. On returning to Istanbul, he worked as a teacher of architecture at the "Sanayi-i Nefise Mekteb-i Alisi", (today's Mimar Sinan University) from March 2, 1883 to August 10, 1908. He was rewarded with Legion d'Honneur in 1896. He died in Istanbul on May 2, 1921. Vallaury's works may be classified as, commercial, cultural, educational, residential and religious buildings. Some of his works may be exemplified as such: Afif Pasha Yalisi (Seaside Residence) at Istinye, Mecid Efendi Kiosk at Bağlarbasşi, Ottoman Bank at Galata and Eminönü, Dümayûn-i (Royal Museum of Archeology) at Sultanahmet, School of Medicine at Haydarpasha, and Greek Orphanage at Büyükada. A. Vallaury fused Ottoman culture and Western forms together in his works. He also designed buildings of free articulation, new measurement and novel proportions. He was a respected Ottoman intellectual, as well.

The Istanbul Protocol (IP) is one of the great success stories of the global anti-torture movement, setting out universal guidelines for the production of rigorous, objective and reliable evidence about allegations of torture and ill-treatment. The IP is explicitly designed to outline 'minimum standards for States'. However, it is all too often left to civil society organizations to investigate allegations of torture and ill-treatment. In this context, important questions remain as to how and where the IP can be used best by such organizations. These questions are particularly acute in situations where human rights groups may have limited institutional capacity. This paper explores the practical challenges faced by civil society in using the IP in Low-Income Countries. It is based on qualitative research in three case studies: Nepal, Kenya and Bangladesh. This research involved over 80 interviews with human rights practitioners. The conclusions of the paper are that the Istanbul Protocol provides a useful framework for documentation, but more comprehensive forms of documentation will often be limited to a very small - albeit important - number of legal cases. In many cases, the creation of precise and standardized forms of evidence is not necessarily the most effective form of documentation for redress or accountability. In the absence of legal systems willing and able to respond effectively to allegations of torture and ill-treatment, there are severe limitations on the practical effectiveness of detailed and technical forms of documentation.

Since the first successful liver transplantation by Starzl et al. in 1967, liver transplantation has become the standard therapy for many liver diseases, mainly chronic liver disease. Most liver transplantations performed in Europe and North America utilize deceased donors while a considerable portion of organ requirements is supplied by living donors in Asian countries including Turkey. The actual history of solid organ transplantation in Turkey began with the pioneering work of Dr. Haberal in collaboration with Thomaz E. Starzl in 1974 in Colorado University at Denver. The first successful solid organ transplantation in Turkey was accomplished by Haberal in 1975 with a living donor renal transplantation. Subsequently, legislations no 2238 and 2594 dated 1979 and 1982, respectively, were passed, paving the way for cadaveric tissue/organ utilization and preservation in Turkey. The first deceased donor liver transplantation and the first living donor liver transplantation were performed in 1988 and 1990, respectively. There are currently 45 liver transplantation centers in Turkey. Of these, 25 are state universities, 8 are private (foundation) universities, 9 are private hospitals, and 3 are training and research hospitals belonging to the Ministry of Health. A total of 7152 liver transplantations were performed in Turkey between January 2002 and May 2014. Of these, 4848 (67.8%) used living donors and 2304 (32.2%) used deceased donors. These figures indicate that, despite widespread organ donation campaigns and media-sponsored propaganda, desired targets have not been met yet in providing deceased organ donation. Despite unsatisfactory levels attained in supplying deceased donors, both the number of annual liver transplantations and improvements in overall survival rates of organ transplanted patients continues to increase. Actually, the one-year patient survival rate after liver transplantation in 2013 was 80.5%. This rate is getting better with each passing year and believed to be close to 90% in the next few years.

Macrolophus pygmaeus (Rambur) (Hemiptera: Miridae) is widely distributed throughout the Palaearctic region. The aim was to explain the current geographic distribution of the species by investigating its genetic population structure. Samples of M. pygmaeus were collected in 15 localities through its range of distribution. A sample from a commercial producer was also analyzed. A total of 367 M. pygmaeus were genotyped for nine microsatellite loci. Isolation by distance was tested by Mantel's test. The molecular structure of M. pygmaeus populations was inferred by UPGMA, AMOVA, Principal component and Bayesian analyses. The average number of alleles per locus per population was 5.5 (range: 3.1–7.8). Istanbul (Turkey) and Nimes (France) had the lowest (0.291) and the highest (0.626) expected heterozygosity (He), respectively. There was an increase in He from the Canary Islands to Nimes, and a progressive decrease thereafter. A significant negative correlation was found between allelic richness and He, and the distance of each population to the easternmost locality (Canary Islands). Significant linkage disequilibrium was observed in the populations from Turkey. FST (0.004–0.334) indicated a high population differentiation, with isolation by distance supported by a high correlation. Bayesian analyses, PCA, and UPGMA pointed to three main clusters: (1) Greece and Turkey, (2) Italy and France, and (3) southern Iberia and the Canary Islands. The recent evolutionary history of M. pygmaeus is inferred from the data as follows: (1) the reduction in the geographic distribution of the species to the Iberian, Italian, and Balkan peninsulas, and possibly southern France, during glaciations and re-colonization of northern Europe from its southern refuges; (2) the maintenance of high diversity in Iberia and Italy (and possibly southern France) during contraction periods, and bottlenecks in the Balkans; (3) introgression of the Italian–French lineage in northern Spain, naturally or through trade.

Turkey has experienced a wave of demonstrations in the summer of 2013, called Gezi Park Demonstrations. Between 31 May and 30 August, 297 people who had been subjected to trauma by several methods of demonstration control and Riot Control Agents applied to the Human Rights Foundation of Turkey Rehabilitation Centers to receive treatment/rehabilitation and/or documentation. 296 patients except one 5-year-old child were included in the study. Of the 296 patients; 175 were male, 120 were female, and one was a transgender individual. The highest number of applications was received by the Istanbul center with 216 patients. The mean age of applicants was 33.85, and the age range was 15-71 years. While 268 of applicants (91%) stated that they had been exposed to Riot Control Agents, 62 patients suffered only chemical exposure who had no other traumatic injuries whereas 234 patients suffered at least one blunt trauma injury. Blunt trauma injuries are due to being shot by gas canisters in 127 patients (43%), by plastic bullets in 31 patients (10%). 59 patients (20%) were severely beaten, and 30 patients (10%) were injured by pressurized cold water ejected by water cannons. Thirteen patients (4.4%) suffered injuries that caused loss of vision or eye. Psychiatric evaluations were carried out for 117 patients while 43% of them were diagnosed with Acute Stress Disorder. Post Traumatic Stress Disorder and Major Depressive Disorder followed this diagnosis. This study includes the medical evaluation of injuries allegedly sustained during Gezi Park demonstrations in 2013 as a result of several methods of demonstration control and/or by being exposed to Riot Control Agents. The aim is to discuss different types of injuries due to those methods and health consequences of Riot Control Agents. Copyright © 2016 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

The aim of this study was to determine whether vancomycin resistant Staphylococcus aureus (VRSA) and vancomycin intermediate susceptible S.aureus (VISA) strains were present among methicillin-resistant S.aureus (MRSA) strains isolated from patients hospitalised at intensive care units (ICU) of hospitals located at different regions of Turkey and to determine the minimum inhibitory concentration (MIC) values of teicoplanin, linezolid, tigecycline, quinupristin-dalfopristin and daptomycin, which are alternative drugs for the treatment of MRSA infections. A total of 260 MRSA clinical strains (isolated from 113 lower respiratory tract, 90 blood, 24 wound, 17 catheter, 13 nasal swabs, two urine and one CSF sample) were collected from nine health-care centers in eight provinces [Ankara (n= 52), Konya (n= 49), Antalya (n= 40), Istanbul (n= 7), Izmir (37), Diyarbakir (n= 15), Van (n= 12), Trabzon (n= 48)] selected as representatives of the seven different geographical regions of Turkey. Methicillin resistance was determined by cefoxitin disk diffusion in the hospitals where the strains were isolated and confirmed by oxacillin salt agar screening at the Refik Saydam National Public Health Agency. Screening for VISA and VRSA was conducted using the agar screening test and E-test. Susceptibility of the MRSA strains to other antibiotics was also determined by E-test method. None of the 260 MRSA strains were determined to be VRSA or VISA. All were susceptible to teicoplanin and linezolid, and susceptibility rates to daptomycin, tigecycline and quinupristin-dalfopristin were 99.6%, 96.9%, and 95%, respectively. Absence of VISA and VRSA among the MRSA strains surveyed currently seemed hopeful, however, continuous surveillance is necessary. In order to prevent the development of VISA and VRSA strains the use of linezolid, tigecycline, quinupristin-dalfopristin and daptomycin should be encouraged as alternative agents of treatment of MRSA infections.

Background: Tuberculosis is a public health problem and its transmission is a threat to the community. Aims: The aim of this study was to determine the factors influencing the treatment outcomes and the effectiveness of the National Tuberculosis Program (NTP) in relation to the application of the directly observed treatment, short-course (DOTS) program in various sites in Istanbul, Turkey. Study Design: Case-Control Study Methods: A case-control study was used, where cases and controls were randomly selected from the Turkish Tuberculosis National Database, which includes complete data on treatment outcomes for patients recorded in the database from January 1, 2006 to December 31, 2009 and had one year follow-up. Results: The case group was composed of 464 patients with adverse outcome, while the control group was composed of 441 patients who had been cured of disease. Factors associated with adverse treatment outcome were >65 years of age (OR: 3.39 (1.99–5.76)) ; male gender (OR:2.11 (1.49–2.99)); born outside Turkey (OR: 5.48 (2.13–14.04)); co-morbidity (OR: 1.85 (1.29–2.65)); bilateral radiologic lesions (OR: 2.07 (1.41–3.00); previous treatment history (OR: 3.99 (2.78–5.74)); 3rd month positive microscopy (OR: 4.96 (3.04–8.09)) and any H&R +/− others multidrug resistant (MDR) resistance (OR: 22.64 (6.92–74.08)). There was no association between the adverse treatment outcome and the application site of direct observation treatment, short course (DOTS) delivery and the supervisors. Conclusion: Our findings indicate similar quality in DOTS application and supervision among patients with or without adverse treatment outcomes. However, patients with certain characteristics should be carefully monitored and aggressively treated. PMID:25207101

The Components of Community Awareness and Preparedness; its Effects on the Reduction of Tsunami Vulnerability and Risk

The resilience of coastal communities against tsunamis are dependent on preparedness of the communities. Preparedness covers social and structural components which increases with the awareness in the community against tsunamis. Therefore, proper evaluation of all components of preparedness will help communities to reduce the adverse effects of tsunamis and increase the overall resilience of communities. On the other hand, the complexity of the metropolitan life with its social and structural components necessitates explicit vulnerability assessments for proper determination of tsunami risk, and development of proper mitigation strategies and recovery plans. Assessing the vulnerability and resilience level of a region against tsunamis and efforts for reducing the tsunami risk are the key components of disaster management. Since increasing the awareness of coastal communities against tsunamis is one of the main objectives of disaster management, then it should be considered as one of the parameter in tsunami risk analysis. In the method named MetHuVA (METU - Metropolitan Human Tsunami Vulnerability Assessment) proposed by Cankaya et al., (2016) and Tufekci et al., (2016), the awareness and preparedness level of the community is revealed to be an indispensable parameter with a great effect on tsunami risk. According to the results obtained from those studies, it becomes important that the awareness and preparedness parameter (n) must be analyzed by considering their interaction and all related components. While increasing awareness can be achieved, vulnerability and risk will be reduced. In this study the components of awareness and preparedness parameter (n) is analyzed in different categories by considering administrative, social, educational, economic and structural preparedness of the coastal communities. Hence the proposed awareness and preparedness parameter can properly be analyzed and further improvements can be achieved in vulnerability and risk analysis. Furthermore, the components of the awareness and preparedness parameter n, is widely investigated in global and local practices by using the method of categorization to determine different levels for different coastal metropolitan areas with different cultures and with different hazard perception. Moreover, consistency between the theoretical maximum and practical applications of parameter n is estimated, discussed and presented. In the applications mainly the Bakirkoy district of Istanbul is analyzed and the results are presented.

The Istanbul Strait, which separates the European and the Asian parts of Istanbul, is one of the narrowest straits in the world that is used for international shipping. The Strait has very special ecological conditions in terms of marine environment (atmospheric/oceanographic conditions, plant and animal diversity) and terrestrial environment. It also has roles as biological corridor and biological barrier between the Mediterranean Sea and the Black Sea and form an acclimatization zone for migrating species. Due to being the only maritime access for the neighboring Black Sea states and the Central Asian Turki Republics, the Istanbul Strait has been exposed to dense marine traffic for centuries and substantial increase has occurred in size and tonnage of the ships passing through the Strait with hazardous cargo varieties and amounts they carry. Increase in the number of vessels that navigates on the Strait and being on the transportation way of hazardous and dangerous materials pose serious environmental and safety hazards for the Istanbul Strait, Marmara Sea and the surrounding residential areas. Geographic and oceanographic features of the Istanbul Strait makes the navigation on the Strait rather difficult and consequently the Strait has faced many casualties that caused severe environmental problems due to thousands tons of oil spill occurring in recent decades.

Regional Climate Modeling over the Marmara Region, Turkey, with Improved Land Cover Data

Sertel, E.; Robock, A.

Land surface controls the partitioning of available energy at the surface between sensible and latent heat,and controls partitioning of available water between evaporation and runoff. Current land cover data available within the regional climate models such as Regional Atmospheric Modeling System (RAMS), the Fifth-Generation NCAR/Penn State Mesoscale Model (MM5) and Weather Research and Forecasting (WRF) was obtained from 1- km Advanced Very High Resolution Radiometer satellite images spanning April 1992 through March 1993 with an unsupervised classification technique. These data are not up-to-date and are not accurate for all regions and some land cover types such as urban areas. Here we introduce new, up-to-date and accurate land cover data for the Marmara Region, Turkey derived from Landsat Enhanced Thematic Mapper images into the WRF regional climate model. We used several image processing techniques to create accurate land cover data from Landsat images obtained between 2001 and 2005. First, all images were atmospherically and radiometrically corrected to minimize contamination effects of atmospheric particles and systematic errors. Then, geometric correction was performed for each image to eliminate geometric distortions and define images in a common coordinate system. Finally, unsupervised and supervised classification techniques were utilized to form the most accurate land cover data yet for the study area. Accuracy assessments of the classifications were performed using error matrix and kappa statistics to find the best classification results. Maximum likelihood classification method gave the most accurate results over the study area. We compared the new land cover data with the default WRF land cover data. WRF land cover data cannot represent urban areas in the cities of Istanbul, Izmit, and Bursa. As an example, both original satellite images and new land cover data showed the expansion of urban areas into the Istanbul metropolitan area, but in the WRF land cover data only a limited area along the Bosporus is shown as urban. In addition, the new land cover data indicate that the northern part of Istanbul is covered by evergreen and deciduous forest (verified by ground truth data), but the WRF data indicate that most of this region is croplands. In the northern part of the Marmara Region, there is bare ground as a result of open mining activities and this class can be identified in our land cover data, whereas the WRF data indicated this region as woodland. We then used this new data set to conduct WRF simulations for one main and two nested domains, where the inner-most domain represents the Marmara Region with 3 km horizontal resolution. The vertical domain of both main and nested domains extends over 28 vertical levels. Initial and boundary conditions were obtained from National Centers for Environmental Prediction-Department of Energy Reanalysis II and the Noah model was selected as the land surface model. Two model simulations were conducted; one with available land cover data and one with the newly created land cover data. Using detailed meteorological station data within the study area, we find that the simulation with the new land cover data set produces better temperature and precipitation simulations for the region, showing the value of accurate land cover data and that changing land cover data can be an important influence on local climate change.

The aim of the study is to describe the inter-province differences in traffic accidents and mortality on roads of Turkey. Two different risk indicators were used to evaluate the road safety performance of the provinces in Turkey. These indicators are the ratios between the number of persons killed in road traffic accidents (1) and the number of accidents (2) (nominators) and their exposure to traffic risk (denominator). Population and the number of registered motor vehicles in the provinces were used as denominators individually. Spatial analyses were performed to the mean annual rate of deaths and to the number of fatal accidents that were calculated for the period of 2001-2006. Empirical Bayes smoothing was used to remove background noise from the raw death and accident rates because of the sparsely populated provinces and small number of accident and death rates of provinces. Global and local spatial autocorrelation analyses were performed to show whether the provinces with high rates of deaths-accidents show clustering or are located closer by chance. The spatial distribution of provinces with high rates of deaths and accidents was nonrandom and detected as clustered with significance of P<0.05 with spatial autocorrelation analyses. Regions with high concentration of fatal accidents and deaths were located in the provinces that contain the roads connecting the Istanbul, Ankara, and Antalya provinces. Accident and death rates were also modeled with some independent variables such as number of motor vehicles, length of roads, and so forth using geographically weighted regression analysis with forward step-wise elimination. The level of statistical significance was taken as P<0.05. Large differences were found between the rates of deaths and accidents according to denominators in the provinces. The geographically weighted regression analyses did significantly better predictions for both accident rates and death rates than did ordinary least regressions, as indicated by adjusted R(2) values. Geographically weighted regression provided values of 0.89-0.99 adjusted R(2) for death and accident rates, compared with 0.88-0.95, respectively, by ordinary least regressions. Geographically weighted regression has the potential to reveal local patterns in the spatial distribution of rates, which would be ignored by the ordinary least regression approach. The application of spatial analysis and modeling of accident statistics and death rates at provincial level in Turkey will help to identification of provinces with outstandingly high accident and death rates. This could help more efficient road safety management in Turkey.

Coccidioidomycosis caused by Coccidioides immitis or Coccidioides posadasii is a rare infectious disease except in endemic regions. In this report the third documented imported case of coccidioidomycosis in Turkey was presented. A thirty-year-old male patient was admitted to our hospital with fever and purulent drainage from his chest tube. He had worked in Arizona, USA, until 4 months before this presentation. While in Arizona, he experienced cough and hemoptysis and was diagnosed as pulmonary coccidioidomycosis. He was treated with itraconazole for two months and he had no symptoms for 3 years. He then returned to Turkey and 2 months after his return to Turkey, he was admitted to another hospital in Istanbul with dyspnea and diagnosed as hydro-pneumothorax, and pleural fluid obtained from the inserted chest tube was found to be purulent. One gram of BID amoxicillin-clavulanate was given. Physical examination on admission revealed a purulent drainage on the right side chest tube, a temperature of 38.5°C and decreased breath sounds on the right lung. Piperacillin-tazobactam 3 x 4.5 g intravenous and fluconazole 400 mg intravenous once daily were started. Human immunodeficiency virus test was negative. Gram-negative diplococci and rods, gram-positive cocci and septate hyphae were seen in the Gram stain of his pleural fluid. Pleural fluid culture revealed Moraxella catarrhalis after 24 hours incubation and a mold after 72 hours of incubation. Anti-coccidioidal antibodies were found positive in a titer of 1/2. Hydro-pneumothorax, atelectasis and a 3 mm nodules in the right lung were seen in his thorax CT. The patient's pleural fluid and the culture plates were sent to the Public Health Institute of Turkey, Mycology Reference Laboratory (PHIT-MRL), with a clinical suspicion of coccidioidomycosis. The specimen and plates were submitted to the PHIT-MRL Bio Safety Level-3 laboratory for mycological evaluation. The microscopic examination of 15% KOH preparations of pleural fluid specimens revealed septate hyphae which appear to be in the early stages of forming arthroconidia. The pleural fluid culture grew buff-white coloured colonies with aerial hyphae, which were suspected of being a Coccidioides spp. The strain was identified as C.immitis/posadasii by direct microscopy and culture, and subsequently confirmed by the FDA-approved DNA probe. DNA sequence analysis of the ITS and D1/D2 rDNA regions confirmed the isolate to be C.posadasii species [ITS 100% match to GenBank Accession No. AB232901 (630/630 base pair match), and D1/D2 100% match to GenBank Accession No. AB232884 (617/617 base pair match)]. ITS1 and ITS2 barcode analysis also confirmed the species to be C.posadasii, which is the species endemic in Arizona. Susceptibility testing was performed according to Clinical and Laboratory Standards Institute M38-A2 guidelines in the Fungus Testing Laboratory of the University of Texas Health Science Center at San Antonio and minimal inhibitory concentration values were; 0.125 µg/ml for amphotericin B, posaconazole and voriconazole, 0.5 µg/ml for itraconazole and 8 µg/ml for fluconazole. He had decortication of the pleura and was discharged from hospital after six weeks treatment with intravenous fluconazole which was continued orally for one year. Anti-coccidioidal antibodies were negative after two months of treatment. The patient is currently asymptomatic. The presented case is the third case reported from Turkey and provides additional contribution to the existing literature with regard to the appearance of arthroconidium, which is the unusual hyphal form, instead of the expected spherules in the infected tissue.

Q Conversion Factor Models for Estimating Precipitable Water Vapor for Turkey

2015-04-01

Global Navigation Satellite Systems (GNSS) have recently proved to be one of the crucial tools for determining continuous and precise precipitable water vapor (GNSS-MET networks). GNSS, especially CORS networks such as CORS-TR (the Turkish Network-RTK), provide high temporal and spatial accuracy for the wet tropospheric zenith delays which are then converted to the precipitable water vapor due to the fact that they can operate in all weather conditions continuously and economically. The accuracy of wet tropospheric zenith delay highly depends on the accuracy of precipitable water vapor content in the troposphere. Therefore, the precipitable water vapor is an important element of the tropospheric zenith delay. A number of studies can be found in the literature on the determination of the precipitable water vapor from the tropospheric zenith delay. Studies of Hogg showed that when the precipitable water vapor is known, the tropospheric zenith delay can be computed. Askne and Nodius have developed fundamental equations between the wet tropospheric zenith delay and the precipitable water vapor from the equation of the index of refraction in the troposphere. Furthermore, Bevis have developed a linear regression model to determine the weighted mean temperature (Tm) depending on the surface temperature (Ts) in Askne and Nodius studies. For this reason, nearly 9000 radiosonde profiles in USA were analyzed and the coefficients calculated. Similarly, there are other studies on the calculation of those coefficients for different regions: Solbrig for Germany, Liou for Taiwan, Jihyun for South Korea, Dongseob for North Korea, Suresh Raju for India, Boutiouta and Lahcene for Algeria, Bokoye for Canada, Baltink for Netherlands and Baltic, Bock for Africa. It is stated that the weighted mean temperature can be found with a root mean square error of ±2-5 K. In addition, there are studies on the calculation of the coefficients globally. Another model for the determination of precipitable water vapor is the conversion factor Q which is shown in Emardson and Derks' studies and also Jade and Vijayan's. Developing a regional model using either Tm-Ts equation or the conversion factor Q will provide a basis for GNSS Meteorology in Turkey which depends on the analysis of the radiosonde profile data. For this purpose, the radiosonde profiles from Istanbul, Ankara, Diyarbaki r, Samsun, Erzurum, Izmir, Isparta and Adana stations are analyzed with the radiosonde analysis algorithm in the context of the 'The Estimation of Atmospheric Water Vapour with GPS' Project which is funded by the Scientific and Technological Research Council of Turkey (TUBITAK). The Project is also in the COST Action ES1206: Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC). In this study, regional models using the conversion factor Q are used for the determination of precipitable water vapor, and applied to the GNSS derived wet tropospheric zenith delays. Henceforth, the estimated precipitable water vapor and the precipitable water vapor obtained from the radiosonde station are compared. The average of the differences between RS and models for Istanbul and Ankara stations are obtained as 2.0±1.6 mm, 1.6±1.6 mm, respectively.

The 12th International Symposium on Continuum Models and Discrete Systems (CMDS-12) (http://www.saha.ac.in/cmp/cmds.12/) took place at the Saha Institute of Nuclear Physics in Kolkata from 21-25 February 2011. Previous CMDS symposia were held in Kielce (Poland, 1975), Mont Gabriel (Canada, 1977), Freudenstadt (Federal Republic of Germany, 1979), Stockholm (Sweden, 1981), Nottingham (United Kingdom, 1985), Dijon (France, 1989), Paderborn (Germany, 1992), Varna (Bulgaria, 1995), Istanbul (Turkey, 1998), Shoresh (Israel, 2003) and Paris (France, 2007). The broad interdisciplinary character, limited number of participants (not exceeding 100) and informal and friendly atmosphere of these meetings has made them a well-acknowledged place to make highly fruitful contacts and exchange ideas, methods and results. The purpose of CMDS is to bring together scientists with different backgrounds who work on continuum theories of discrete mechanical and thermodynamical systems in the fields of mathematics, theoretical and applied mechanics, physics, material science, and engineering. The spirit of the CMDS meetings is to stimulate extensive and active interdisciplinary research. The International Scientific Committee members of this conference were: David J Bergman (Chairman CMDS 10), Tel Aviv University, Israel; Bikas K Chakrabarti (Chairman CMDS 12), Saha Institute of Nuclear Physics, India; Alex Hansen, Norwegian University of Science and Technology, Norway; Hans Jürgen Herrmann, Institute for Building Materials, ETH, Switzerland; Esin Inan (Chairman CMDS 9), Istanbul Technical University, Turkey; Dominique Jeulin (Chairman CMDS 11), Ecole des Mines de Paris, France; Frank Juelicher, Max-Planck-Institute for the Physics of Complex Systems, Germany; Hikaru Kawamura, University of Osaka, Japan; Graeme Milton, University of Utah, USA; Natalia Movchan, University of Liverpool, UK; and Ping Sheng, The Hong Kong University of Science and Technology, Hong Kong. At CMDS-12 the topics of interest were: Thermodynamics, transport theory and statistical mechanics in the context of continuum modeling discrete systems; Statistical mechanics and dynamics of fluid flows; Continuum mechanics of complex fluids and deformable solids with microstructure; Fundamentals of fracture, defect dynamics, fatigue, and fracture dynamics; Statics and dynamics of dislocations, dislocation mediated phase transitions and plasticity; Granular materials: statics and dynamics; Physics and mechanics of earthquakes; Transport in composite materials; and Continuum theory of soft matter systems of biological motivation and living structures. The scientific program consisted of General Lectures and Research Communications. The four General Lectures (40 min + 5 min) introduced the most recent ideas and advances in the fields covered. The 25 Research Communications reported new results and methods in these fields and were presented orally (30 min + 5 min). In addition there were 15 posters which also presented interesting results and five of these posters were selected by a special committee chaired by David J Bergman to contribute to this proceedings. The selected five posters were presented by Moutushi D Choudhury, Morten Grova, Arya Paul, Arnab Saha and Amartya Sarkar. We were happy to note that 32 scientists from ten countries and a large number of students (both from India and other countries) participated in this symposium. The talks and poster sessions generated a lot of discussions, arguments and collaborations. The articles that appear in this proceedings are based on the invited talks and selected poster presentations. We would like to thank the Journal of Physics Conference Series (IOP Publishing) for publishing the proceedings of the conference.

OBJECTIVE: The aim of this study was to determine an orthorexia nervosa scale score for and evaluate orthorexic tendency among students of nutrition and dietetics according to various sociodemographic characteristics. METHODS: This cross-sectional study was carried out in May and June of 2016 among 208 students in the nutrition and dietetics department at a university in Istanbul. After receiving the approval of the university ethics committee, of a total of 300 students, 208 agreed to join the study. Participants completed a questionnaire related to individual characteristics and the ORTO-11 scale during a face-to-face interview. The ORTO-11 scale is a verified Turkish scoring system in which a low score indicates orthorexic tendency. The Mann-Whitney U test, independent samples t-test, Kruskal-Wallis test, and analysis of variance were used to assess the data. P<0.05 was accepted as statistically significant. RESULTS: Orthorexic tendency was significantly higher in males (p=0.050) and students who lived with their family (p=0.002). Mean ORTHO-11 scale score did not differ significantly between groups when the participants were grouped by parameters of smoking, alcohol consumption, chronic disease status, body mass index, diet observance, or use of nutritional supplement products. CONCLUSION: The orthorexic tendency was higher in men and in students who lived with their family. Additional assessment of individual eating habits, eating behavior, and personality characteristics would shed light on the reasons for the difference between gender groups. Qualitative studies should be carried out and possible confounding factors should be determined. PMID:28971168

Ozcep, Ferhat

2016-04-01

In the modern sense, geophysics started with geomagnetic works in the 1600s in Ottoman geography. The period between 1600 and 1800 includes the measurement of magnetic declination, inclination and magnetic field strength. Before these years, there is a little information, such as how to use a compass, in the Kitab-i Bahriye (the Book of Navigation) of Piri Reis, who is one of the most important mariners of the Ottoman Empire. However, this may not mean that magnetic declination was generally understood. The first Turkish scientific book relating to terrestrial magnetism is the book of Fuyuzat-i Miknatissiye that was translated by Ibrahim Müteferrika and printed in 1731. The subject of this book is earth's magnetism. Magnetic compass was mentioned in several books. These areMuhammed al Awfi's "Jami al- Hikayat" (translated into Turkish by Ibn Arabşah); Piri Reis's Kitab-I Bahriye (The Book of "Navigation" or "Seafaring" or "Sea"); Seydi Ali Reis's "Risale-i Mirat-I Kainat min Alat-I Irtifa" (The Treatise called the Mirror of Universe according to the instrument for measuring Altitude) and Kitab Al-"Muhit" Fi˙Ilm'al-Eflak Va'l Abhur (Book of the Regional Seas and the Science of Astronomy and Navigation). There are two original magnetic declination determinations in Istanbul in 1727 and 1893 by Ottoman Turks. Also, many geomagnetic measurements between 1600 and 1917 were carried out during international campaigns in Ottoman geography.This study was carried out in History and Philosophy of Science, University of Cambridge and supported by Istanbul University Reseach Project Unite (project Numbver: IRP-49162).

Demirci, E.; Baykal, C.; Guler, I.

2016-12-01

In this study, hydrodynamic conditions due to river discharge, wave action and sea level fluctuations within a seven month period and the morphological response of the Manavgat river mouth are modeled with XBeach, a two-dimensional depth-averaged (2DH) numerical model developed to compute the natural coastal response during time-varying storm and hurricane conditions (Roelvink et al., 2010). The study area shows an active behavior on its nearshore morphology, thus, two jetties were constructed at the river mouth between years 1996-2000. Recently, Demirci et al. (2016) has studied the impacts of an excess river discharge and concurrent wave action and tidal fluctuations on the Manavgat river mouth morphology for the duration of 12 days (December 4th and 15th, 1998) while the construction of jetties were carried on. It is concluded that XBeach has presumed the final morphology fairly well with the calibrated set of input parameters. Here, the river mouth modeled at a further past date before the construction of jetties with the similar set of input parameters (between August 1st, 1995-March 8th, 1996) to reveal the drastic morphologic change near the mouth due to high river discharge and severe storms happened in a longer period of time. Wave climate effect is determined with the wave hindcasting model, W61, developed by Middle East Technical University-OERC with the NCEP-CFSR wind data as well as the sea level data. River discharge, wave and sea level data are introduced as input parameters in the XBeach numerical model and the final output morphological change is compared with the final bed level measurements.

Takahashi, Narumi; Shimizu, Satoshi; Maekawa, Takuya; Kalafat, Dogan; Pinar, Ali; Citak, Seckin; Kaneda, Yoshiyuki

2015-04-01

We have carried out a collaboration study between Japan and Turkey since 2013, which is one of SATREPS projects, "Earthquake and Tsunami Disaster Mitigation in The Marmara Region and Disaster Education in Turkey". The main objective of this project is to reduce risk brought by earthquakes and tsunamis. In particular, the North Anatolian Fault system runs through the Marmara sea and it is expected that the seismic gap exists there according to past seismic studies. The details of seismicity distribution in the Marmara Sea is, however, still insufficient to construct fault model along the active faults. Therefore, we prepare ten ocean bottom seismographs (OBSs) to realize long term observation. We aim to identify size and depth of seismogenic zones using micro seismicity. In addition, we need to cover relative broad area from off-shore Istanbul city to the western end of the Marmara Sea. To clear these conditions, OBS specifications we need are high dynamic range and low instrument noise to observe micro seismicity, low electrical consumption to realize long term observation of over one year, high cost performance to cover the broad area for OBS installation, low cost implementation, and good operability to treat by relatively small number of persons. All items, which are three components velocity sensor, batteries, a recorder, a GPS receiver, a transponder and its transducer to control OBS retrieval, a flasher and a beacon, are installed in the 17 inches glass sphere. The natural frequency of the velocity sensor is 4.5 Hz and the frequency range of our OBS is from 4.5 Hz to 250 Hz. Data sampling is selectable among 100 Hz, 250 Hz and 500 Hz. Because our OBS is deployed by free fall, accuracy of the OBS clock is essentially one of important factors, and it is less than 0.1 ppm. And the resolution of A/D conversion performed on the recorder is 24 bit and we keep the dynamic range of over 135 dB. These data is stored on a semiconductor memory and the capacity is over 300 days with 100 Hz sampling observation. We adopted noncontact charge using lithium ion batteries to reduce implementation cost. And we can charge batteries and transfer stored data without opening glass sphere. All parameters of each OBS are controlled using wireless LAN. In this presentation, we introduce details of OBS development for Japan-Turkey project.

Background: Wellbeing is one’s evaluation and judgment of one’s life. It consists of 3 dimensions: positive affectivity, negative affectivity, and life satisfaction. Objectives: This study aimed to compare the subjective wellbeing and positive future expectations between working and nonworking adolescents. Patients and Methods: The study was designed as descriptive and comparative. The study sample consisted of 420 working and 482 nonworking adolescents (n = 902) aged 15 - 20 years, who were randomly recruited from two occupational education centers in Istanbul, Turkey and two high schools (formal educations) in the same district. Results: Adolescent subjective wellbeing scale (ASWS) total mean (SD) scores for working adolescents and nonworking adolescents were 48.76 (9.50) and 49.72 (8.01), respectively. In addition, positive future expectations scale (PFES) total mean (SD) scores for working adolescents and nonworking adolescents were 18.71 (4.50) and 19.06 (3.49), respectively. In this study, no significant difference was found between the general wellbeing (scale total median score) scores of the working and nonworking adolescent groups (Z = 1.01, P = 0.315). However, significant differences were found in the family relations satisfaction (Z = 3.23, P = 0.002) and relations with significant others (Z = 2.85, P = 0.004) subscales of the ASWS. Conclusions: A positive relationship was found between adolescent subjective wellbeing and positive future expectations. It was found that nonworking adolescents scored higher on the dimensions of “family relations” and “relations with significant others” of subjective wellbeing compared to those dimensions in working adolescents.

The aim of this pilot study was to analyze the data obtained from a retrospective examination of the records of the existing reimbursement system and through the identification of gaps in the data to create a foundation for a reliable, descriptive national registry system for our country. The Social Security Institution Medical Messenger (MEDULA) records were scanned for the years 2010-2014, and the numbers of total knee arthroplasty applied for a diagnosis of gonarthrosis and the numbers of revision knee arthroplasty were recorded for the country in general. The patients were classified according to age, gender, and bilateral or unilateral surgery. The institution where the surgery was applied, the geographic region and the province were also recorded. A total of 283,400 primary and 9900 revision knee arthroplasty operations were applied in Turkey between 2010 and 2014. Numbers were recorded for each year, and there was found to be an increase between years. For primary knee arthroplasty, the female:male ratio was 67 of 33, and surgery was applied most often between the ages of 60-69 years. Both types of surgery were determined to have been applied most often in second-stage state hospitals. Geographically, both types of surgery were applied most in the Marmara region, with the highest frequency of primary knee arthroplasty in Istanbul and the highest frequency of revision surgery in Ankara. The data obtained from this study will contribute to the creation of the basis for a National Registry System and thereby define more scientific treatment approaches. Copyright © 2016 Elsevier Inc.

The aim of the study was to investigate the long-term effects of torture in a group of former political prisoners. The study was carried out in Istanbul, Turkey, where 55 Turkish political activists who had been tortured were compared with a closely matched group of 55 activists who had not been tortured. The Structured Clinical Interview for DSM-III-R, the Semistructured Interview for Survivors of Torture, and other self-rated and assessor-rated measures of anxiety, depression, and posttraumatic stress disorder (PTSD) were used. The tortured and the nontortured activists were similar in age, sex, marital and socioeconomic status, political ideology, political involvement, stressful life events other than torture, and other features. The torture survivors reported an average of 291 exposures to a mean of 23 forms of torture. The mean length of their imprisonment was 47 months. The survivors of torture had significantly more symptoms of PTSD and anxiety/depression than the nontortured comparison subjects, although their PTSD symptoms were only moderately severe and their general mood was normal. Despite the severity of their torture experiences, the survivors had only a moderate level of psychopathology. The results suggest that torture has long-term psychological effects independent of those related to uprooting, refugee status, and other traumatic life events in a politically repressive environment. Prior knowledge of and preparedness for torture, strong commitment to a cause, immunization against traumatic stress as a result of repeated exposure, and strong social supports appear to have protective value against PTSD in survivors of torture.

The aims of this study were to evaluate the posttreatment outcomes in a postgraduate orthodontic clinic following a course on American Board of Orthodontics Cast and Radiograph Evaluation (ABO-CRE); to compare the outcomes of postgraduate students who took the course before and after finishing treatment of their cases; and to assess if the need for orthodontic treatment as determined by the Index of Orthodontic Treatment Need (IOTN) at the beginning of treatment affected students' final scores. A course on ABO-CRE was given to second- (group A), third- (group B), and fourth- (group C) year postgraduate students at Yeditepe University, Istanbul, Turkey, in 2012. Pre- and posttreatment plaster models of 253 cases (group A) were treated by students in 2011-12. An additional 251 (group B, 2012-13) and 341 (group C, 2013-14) cases were evaluated in the first and second years after the course, respectively. The models were graded retrospectively using the ABO-CRE and IOTN. The results showed that the total mean scores on the posttreatment plaster models were significantly higher in the pre-course group than the first- and second-year post-course group (p<0.05 and p<0.01, respectively). The borderline cases (grade 3) received a lower score on the ABO-CRE than the cases with need (grade 4) (p<0.01) and severe need (grade 5) (p<0.01) for orthodontic treatment. Increasing awareness by giving information about the ABO-CRE significantly improved the posttreatment success of these postgraduate students. After the course, treatment outcomes in the following year were better than two years later, suggesting it may be useful to teach the course annually to refresh students' knowledge.

Aspergillus species cause a wide range of diseases in humans, including allergies, localized infections, or fatal disseminated diseases. Rapid detection and identification of Aspergillus spp. facilitate effective patient management. In the current study we compared conventional morphological methods with PCR sequencing, rep-PCR, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) for the identification of Aspergillus strains. A total of 24 consecutive clinical isolates of Aspergillus were collected during 2012-2014. Conventional morphology and rep-PCR were performed in our Mycology Laboratory. The identification, evaluation, and reporting of strains using MALDI-TOF-MS were performed by BioMérieux Diagnostic, Inc. in Istanbul. DNA sequence analysis of the clinical isolates was performed by the BMLabosis laboratory in Ankara. Samples consisted of 18 (75%) lower respiratory tract specimens, 3 otomycosis (12.5%) ear tissues, 1 sample from keratitis, and 1 sample from a cutaneous wound. According to DNA sequence analysis, 12 (50%) specimens were identified as A. fumigatus, 8 (33.3%) as A. flavus, 3 (12.5%) as A. niger, and 1 (4.2%) as A. terreus. Statistically, there was good agreement between the conventional morphology and rep-PCR and MALDI-TOF methods; kappa values were κ = 0.869, 0.871, and 0.916, respectively (P < 0.001). The good level of agreement between the methods included in the present study and sequence method could be due to the identification of Aspergillus strains that were commonly encountered. Therefore, it was concluded that studies conducted with a higher number of isolates, which include other Aspergillus strains, are required. © 2016 Wiley Periodicals, Inc.

Smoking is one of the major causes of preventable diseases, disability and death in the globe and Turkey. In our study, the knowledge of students about smoking addiction and which organ in the body is damaged due to smoking are aimed to be determined. Surveys were applied to students of private university preparatory training center on the Anatolian side of Istanbul. In the conducted survey, the questions related with students' demographic characteristics, themselves, their families and friends smoking addiction, the reasons to start smoking, whether they want to quit smoking, whether they try to quit smoking and which of the organs that they know smoking is harmful were asked. The data obtained were transferred to the Statistical Package for the Social Sciences (SPSS) for Windows. Out of 358 students who answered the survey completely, 152 students (42.4%) were male, 206 (57.6%) were female. Students were between the ages of 16-20 and the mean age was 18 ± 1.15. When asked about their smoking addiction, 84 (23.5%) of total actively continued to smoke. Total of 14 students (3.9%) smoked and then stopped smoking, 260 students (72.6%) have never smoked. Curiosity was the most commonly reported reason to start smoking (39%) and for the second row, they indicated to start smoking due to tobacco user friends (30.6%). More and more young people begin smoking at an earlier age and they transfer the problems of this bad addiction to the later years of their lives. There should be fight resolutely against actions and conditions encouraging smoking both as a state and society and in order to rescue young people from this bad addiction, it should continue to take steps which facilitate accessibility to supportive institutions.

This study aims to evaluate the demographic characteristics, tumor stage, surgical treatment and recurrence rate among patients operated with a juvenile nasopharyngeal angiofibroma. This retrospective study included 45 patients (44 males, 1 female; mean age 21 years, range 9 to 55 years) who underwent surgery at Istanbul University, Istanbul Medical Faculty, Department of Otorhinolaryngology clinic between March 2006 and July 2015. The patients were classified according to age, sex, presenting symptom, tumor stage, surgical procedure applied, preoperative embolization, perioperative blood transfusion, complications, and the presence of recurrence. The most common presenting symptoms were epistaxis (78%) and nasal obstruction (73%). Preoperative angiography was performed on all patients and embolization was applied in eligible patients (69%). Transnasal endoscopic approach in 31 patients, midfacial degloving in six patients, and lateral rhinotomy approach in three patients were applied. The overall recurrence rate was 31% (n=14). The most important factor in determining the risk of postoperative recurrence is the preoperative tumor stage. Preoperative embolization reduces the amount of perioperative bleeding. Endoscopic transnasal approach decreases the rate of complications and length of hospitalization.

For the past few years, the social, economic, and political issues surrounding the field of organ transplantation have entered into many ethical discussions. Transplant tourism, and organ trade in particular, have finally received the attention they deserve and many commendable developments have ensued. The "Declaration of Istanbul on Organ Trafficking and Transplant Tourism," the result of a collective effort by hundreds of transplant professionals the world over, is one such example and is now considered the universal charter for ethical conduct in the field of transplantation. The Middle East Society for Organ Transplantation and its official journal Experimental and Clinical Transplantation were among its first endorsers, and it is our policy to ensure that all authors of articles published in our Journal adhere fully to the rules and regulations stated in The Declaration of Istanbul and by the Committee on Publication Ethics. We believe that the medical community must ensure that a foundation of ethical conduct and scientific integrity is maintained throughout the field, and we must strive toward this goal in all our clinical and scholarly efforts.

The point kinetics approach is a classical useful method for a reactor transient analysis. It is helpful to known, however, when a more elaborate transient analysis, involving the space-dependence change of the flux through a given transient, should be considered. In this paper, the authors present a rather elegant and quick method to check the need for a space-dependent flux analysis through a control rod transient in a given nuclear reactor. The method is applied to a series of rod ejection experiments in the TRIGA MARK-II reactor of Istanbul Technical University (ITU).
