Mathematical Programming and Simulation Approaches for Location Problems of Urban Search and Rescue Teams: Case Study of Istanbul

Afet aniden ortaya çıkan ve insan hayatını kesintiye uğratan doğa olaylarıdır. Deprem ise afet türleri içerisinde ortaya çıktıktan sonra yıkıcı etkisini uzun süre gösteren afet türüdür. Bu çalışmanın amacı, deprem sonrasında arama kurtarma birliklerinin bir planlama ufku süresince depremden etkilenen bölgelere mevcut birlik sayılarına ek olarak tiplerine göre birlik sayılarını bulmaktır. Çalışmada oluşturulan matematiksel modelde birincil ve ikincil kapsama alanları arasında gönderilecek birlikler aynı kapsama bölgesinden gelen talepleri risk baskı faktörü büyüklüğüne göre sıralamaktadır. Matematiksel modelden elde edilen sonuçlar simülasyon deneyi ile test edilerek matematiksel modelin geçerliliği test edilmiş ve arama kurtarma birliği ihtiyacı belirlenmiştir.Natural disasters are catastrophic phenomena that disrupt people’s lives. Earthquakes are a kind of natural disasters that has long lasting destructive effects. The aim of this study, the number and types of the additional search and rescue teams needed by different regions after an earthquake is determined. In the modeling of problem, the available units try to respond to the demands of primary and secondary coverage areas after responding to the demands of their own regions first. The obtained solution is tested with simulations to validate the mathematical model. In the results section, the need for search and rescue teams emerging in case of an earthquake is determined at the end of the planning process

The levels of burnout among the physicians pursuing postgraduate training

Bu çalışmada Çukurova Üniversitesi Tıp Fakültesi hastanesi’nde çalışan tıpta uzmanlık öğrencisi hekimlerin tükenme düzeyleri ile bunun, aleksitimi ve sosyodemografik değişkenlerle ilişkisi araştırılmıştır. Çalışmaya 174 hekim katılmıştır. Sonuçta duygusal tükenme, duyarsızlaşma ve aleksitimi düzeyleriyle kişisel başarı düzeyleri arasında negatif ilişki belirlenmiştir. Yaşla, günlük uyku saatiyle ve çalışma süresiyle duyarsızlaşma düzeyleri arasında negatif ilişki varken, nöbet sayısı ve nöbet dışı günlük çalışma saatiyle duyarsızlaşma düzeyleri arasında pozitif ilişki bulunmuştur. Bekarlarda duygusal tükenme ve aleksitimi daha yüksektir. Geleceğe yönelik olarak akademik çalışma ya da aşama yapmayı düşünenlerde duygusal tükenme düşük; karamsar, umutsuz ve gelecekten beklentisi olmayanlarda ise kişisel başarı düşük, duygusal tükenme ve duyarsızlaşma yüksektir. Yaşamsal zor olarak iş yaşamını bildirenlerde duygusal tükenme ve duyarsızlaşma yüksek, kişisel başarı düşük olarak bulunmuştur. Sonuçlar yurtiçi ve yurtdışı yazın ışığında tartışılmıştır.This study investigates the levels of burnout and its relationship with the sociodemographic variables and alexithymia in a sample consisting of 174 physicians pursuing postgraduate training at the Medical School of Çukurova University. The results indicated a negative relationship between levels of emotional exhaustion, depersonalization, alexithymia and personal accomplishment. Age, daily sleeping hours and years of experience had a negative relationship with levels of depersonalization; whereas daily working hours and number of night watches had a positive relationship. The levels of emotional exhaustion and alexithymia were found to be higher among singles. The physicians who were hopeless and pessimistic, and reported work-related problems as the major stressor in their life, had higher levels of emotional exhaustion, depersonalization and lower levels of personal accomplishment. Our results are discussed along with the relevant literature

Adaptation to Turkish and Reliability Study of the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R)

WOS: 000383254700007PubMed ID: 28373799Introduction: Amyotrophic lateral sclerosis (ALS) is a fatal disease characterized by progressive degeneration of the motor neurons. It is difficult to define the severity of the clinical findings of this destructive disease owing to its rapid progression, which presents serious alterations in a short time even in the same patient. The present study was designed to evaulate the validity of the Turkish version of the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R), which has been used in various countries for measuring the functional status of ALS patients. Methods: The ALSFRS-R scores of 41 ALS patients (24 male), in any stages of illness, were simultaneously assessed by two physicians. The functional status of the patients (motor system, bulbar, and pulmonary functions) was evaluated under 12 titles. In every subtitle, the functional status was evaluated as 0 for the worst functional status and 4 for the best functional status. The mean differentials for both subtitles and global scores and the 95% confidence bounds of these means were detected. The coherence was defined as the states in which the coefficient is above 0.80 and is statistically significant Results: From the data obtained, the correlation between the two physicians was found to be statistically significant (p=0.000) in terms of the means of both subtitles and total scores. Conclusion: It was shown in the present study that in the clinical follow-up of the disease, the Turkish version of ALSFRS-R is a simple, reliable, and easily applicable

Examıning impacts of natural sciences education in comparison with health and socıal sciences for pro-environmental behaviours in Turkey

Analysis of academic programmes has become very important for pro-environmental behaviours; however, impacts of natural, social and health sciences education for environmental knowledge and behaviours have not been investigated yet. Therefore, the aim of this study was to examine these impacts on environmental knowledge and relation with environmental behaviours of 706 university students. According to findings of study, health sciences students differed from other groups in environmental knowledge, however, no differences in terms of behaviours. Another major finding is: there is a statistically significant negative correlation between environmental behaviour and environmental knowledge for all students and especially for ‘health sciences’ (r = - 0.208; p < 0.01) and ‘natural sciences’ students (r = - 0.131; p < 0.05), contrary to our expectations. For items supporting ‘consumer behaviours’, majority of students indicated they had engaged in environmentally protective behaviours. For example, ‘90.4% stated to turn off unneccessary lights’ (item 4); 79.1% tried to use both sides of papers (item 12) and 77.9% preferred public transportation (item 5). However, these high scores could be interpreted in terms of economical benefits rather than behaving environmentally. In conclusion, students did not have ‘internalized ethical values’ enabling them to behave actually environmental way by feeling themselves as part of nature. © 2015 Taylor & Francis

CT-based morphometric data of L3-L5 vertebrae: Anatomic and surgical approach

Vertebral morphometric studies provide information for both the diagnosis of spinal canal deformity and the design of spinal instrumentations and anthropometric models. This study sought to gather computed tomography-based morphometric data of the L3-L5 vertebrae in healthy adults. The computed tomography scans of 103 normal individuals (47 males and 56 females) of 20 to 51 years of age were studied to provide quantitative anatomic analyses on lumbar vertebrae at the L3-L5 level. In each lumbar vertebrae, the anterior and posterior heights of the vertebral body and disc, the height and width of the pedicle, and the diameters of the spinal canal were measured. Comparisons were made and associations were investigated. Significant differences were found between males and females for the mean dimensions of the vertebral bodies and for the disc heights (0.001<P<0.05). Disc heights also showed a significant decrease in a craniocaudal sequence in both sex (P<0.000). The mean depth and width of the lumbar spinal canal increased progressively from L3 to L5 vertebrae (P<0.000). Significant positive relationships were found between the upper and lower end-plate measurements (0.683<r<0.852). These morphometric data may provide useful information for the calculation of the anthropometric indices, which meet the changing clinical and surgical demands. © 2007 Lippincott Williams & Wilkins, Inc
