Psikiyatri - Abstract
research Şizofreni hastalarının düşünce kalıpları, akıl yürütme ve karar verme süreçleri ilgi çekici ve şaşırtıcıdır. Çalışmamızın amacı, paranoid tip şizofreni olan hastaların karar verme, akıl yürütme, akıl yürütmelerine güven dereceleri ve kararlarını sürdürmedeki sebatlarının Tümevarımsal Kanıtlarla Akıl Yürütme Testi (TKAYT) kullanılarak değerlendirilmesidir. Çalışmaya 32 delüzyonel hasta ve 30 sağlıklı gönüllü dahil edildi. Araştırmaya çağrılan hastalarla SCID-I ile tanı görüşmesi yapıldıktan sonra çıkarımsal (inferansiyel) düşünme biçimlerini tespit etmek için görüşmeci tarafından TKAYT testi uygulandı. Delüzyonel bozukluk grubunun ve kontrol grubunun her bir RIAT maddesi için ilk inanç düzeyleri arasındaki fark, üçüncü madde dışında istatistiksel olarak anlamsızdı. Delüzyonel bozukluğa sahip hasta grubu ile sağlıklı kontrol grubunun RIAT ifadeleri (maddeleri) okunduktan sonra; çıkardıkları ilk sonuca inanma düzeyi ile alternatifleri gördükten sonraki inanma düzeyi (RIAT önceki ve sonraki inanma düzeyi) arasındaki değişimlerle, ANOVA sonuçlarına göre iki grubun önceki ve sonraki RIAT maddelerine inanma düzeyleri açısından oluşan değişimler arasında anlamlı fark saptanmadı (p>0,05). Çalışmamıza göre, delüzyonel alan dışında, hastaların karar vermelerinin normal olduğu söylenebilir. Çalışmamız, delüzyonel bozukluğa sahip hastaların, aynı miktarda veri sunulduğunda ulaştıkları sonuçtaki eminlik düzeyinin sağlıklı kontrollerle benzer olduğunu ve yeni veriler sunulduğunda, başlangıç inanç düzeylerinin değişme oranlarının kontrol grubuyla benzer şekilde olduğunu göstermiştir. Thinking patterns, reasoning and decision making processes of individuals with schizophrenia have been intriguing. The goal of our study is to evaluate the decision making and reasoning of the paranoid type schizophrenic patients, and their confidence in reasoning and perseverance in keeping to their decisions, using Reasoning with Inductive Argument Test (RIAT). Thirty-two delusional patients and 30 healthy volunteers were included in the study. After diagnostic interview conducted by SCID-I, patients were asked to participate in the study, RIAT test was applied by the interviewer in order to detect the inferential thinking patterns. Apart from the 3rd item of RIAT out of 11, the differences of initial scores between the delusional patient group and control group are statistically insignificant. After RIAT items of both delusional patient and control group are read, compared to ANOVA results of the difference between the belief levels in the result of their initial reasoning and after seeing the alternatives (RIAT belief level before and after), no significant differences were detected for both groups in terms of changes between the belief levels to RIAT items before and after (p>0.05). According to our study, apart from the area of delusions, it can be declared that the reasoning of the patients is normal. Our study indicates that when the delusional patients are compared to the control group in terms of jumping to conclusion and modifying their initial beliefs, they are not different, given similarly sufficient amount of data.

research Amaç: Sağlık Bakımı ile İlişkili Pnömoniler (SBİP), sağlık hizmetlerinin yaygınlaşması ile önemi gittikçe artan, yüksek mortalite ve morbiditeye sahip hasta grubudur. Çalışmamızın amacı, göğüs hastanesinde SBİP tanısı ile tedavi edilmiş ve solunum örneklerinde etken üretilebilmiş hastaların yaş, cinsiyet, etken spektrumu, yatış süresi, yoğun bakım gereksinimi, tedaviye yanıt ve ölüm oranları yönünden SBIP kriterlerleri de gözönüne alınarak değerlendirilmesidir.Gereç ve Yöntemler: Ocak 2013-Temmuz 2014 tarihleri arasında Çorum Göğüs Hastalıkları Hastanesi'nde yatarak tedavi edilen Sağlık Bakımı İlişkili Pnömoni hastalarından, balgam/solunum yolu örneklerinde etken üretilebilmiş olan 52 olgu; yaş, cinsiyet, eşlik eden kronik hastalıklar, etken spektrumu, yatış süreleri, yoğun bakım ihtiyacı, başlangıç tedavisin yanıt ve ölüm oranı açısından retrospektif olarak incelendi.Bulgular: Toplam 52 olgu; 35 erkek (%67), 17 kadın (%33) hastadan oluşuyordu. Yaş ortalaması 71.87 bulundu. En sık görülen ek hastalık 42 (%81) olgu ile KOAH'tı. Yirmialtı hastada (%50) yoğun bakım gereksinimi ortaya çıktı. Nörolojik komorbidite YBÜ ihtiyacı (%88) ve mortalite (%77) için anlamlı risk faktörü olarak saptandı. Toplam 22 hasta (%42) kaybedildi. Başlangıç ampirik antibiyotik tedavisine göre takipte antibiyotik değişikliği gereksiniminde ve mortalitede anlamlı farklılık saptanmadı. Etkenlere göre mortalite oranında 13 hasta ile (%65) A. Baumanii ilk sırada yer aldı.Sonuç: Sağlık bakımı ilişkili pnömoni hastalarında tedavi başlangıcında seçilen antibiyotik rejiminin daha geniş spektrumlu tercih edilmesi ile mortalite ve yoğun bakım gereksiniminde azalma saptanmamıştır. Objective: Healthcare-associated Pneumonia (HCAP) gaining importance as healthcare services getting more accessible. In recent studies, suspicion started to rise about the benefits of broad spectrum antibiotics applied empirically because of healthcare related pneumonia criteria. The aim of this study is to assess HCAP patients to see the difference between broad spectrum antibiotic therapy against narrow spectrum. Method: Having been treated in a chest diseases hospital between January 2013 and July 2014, 52 cases of healthcare-associated pneumonia who had positive cultures for sputum/respiratory tract samples were retrospectively examined in age, sex, comorbid diseases, isolated agent, length of hospitalization, intensive care requirement, need for a change in antibiotics depending on the first line treatment and mortality rate.Results: Thirty-five men (67%) and 17 women (33%) were evaluated. The mean age was 71.87 years. Most common comorbidity was COPD (81%). Twenty-six patients (50%) were in need of intensive care. Neurological diseases were found to be most related with intensive care requirement (88%). Twenty-two patients (42%) were died. A. Baumanii ranked the first with 13 patients (65%) for mortality rate according to agents. Conclusion: In our study, no significant difference found between broad spectrum antibiotics group and the others in terms of mortality and need for ICU.

Recently the numbers of distance education programs and students enrolling in them have increased significantly. This increase also carries the question of what factors may have an effect on academic success. The demographic features, motivation levels, personal development status and basic computer literacy of students have been taken into account and their effects on the academic success of students have been analyzed. With this purpose, surveys prepared with the help of professional opinion have been applied to certain groups. The sample group of this study consists students of the Kırıkkale University Distance Education Center and the formal education students of the Kırıkkale Vocational School. The results have been analyzed with the help of the SPSS data analysis program (version 22.0) and have been turned into figures. The academic success of distance learning students and formal education students have been compared and this data has been used to identify whether there are any significant connections between academic success and the factors determined. In the conclusion of this study, the figures have been explained separately, and suggestions have been made regarding both distance education and formal education., Son zamanlarda, yüksek öğretim kurumlarında çok sayıda uzaktan eğitimprogramının açıldığı ve kayıtlı öğrenci sayılarında ciddi artışlar olduğugözlenmektedir. Uzaktan eğitimde öğrenci sayısındaki artışlar eğitimde başarıyıetkileyebilecek faktörlerin neler olabileceği sorusunu beraberinde getirmektedir.Bu çalışmada, uzaktan ve örgün eğitim öğrencilerinin demografik özellikleri,motivasyon seviyeleri, kişisel gelişim durumları ve temel bilgisayar kullanımseviyelerinin akademik başarılarına olan etkisi araştırılmıştır. Bu amaçla,uzman görüşleri alınarak anket soruları hazırlanmış ve gruplara uygulanmıştır.Araştırmanın örneklemini, Kırıkkale Üniversitesi Uzaktan Eğitim Merkezinde eğitimalan öğrencilerle Meslek Yüksekokulun’da örgün olarak öğrenim gören öğrencileroluşturmaktadır.

Elektromekanik supap (EMS) sistemleri içten yanmalı motorlarda kam milinden bağımsız bir çalışma sağlamaktadır. Bu özelliği sayesinde sonsuz değişkenlikte supap zamanlamasına imkân vermektedir. EMS mekanizmaları supabı çok kısa sürede açıp kapatmalı ve güvenilir bir supap performansı sağlamalıdır. EMS sistemleri, içten yanmalı motorlarda motor performansını yükseltip, özgül yakıt tüketimini ve çevreye atılan kirletici oranlarını azaltmaktadır. Bu çalışmada, düşük voltajlarla çalışabilen bir EMS mekanizmasının deney motoru silindir kapağına montajı yapılarak, motorun orijinal supap sistemi ve EMS sistemi ile performans ve emisyon testleri gerçekleştirilmiştir. The camshaft electro-mechanical valve (EMV) system, unlike conventional camshaft system, provides an independent performance in internal combustion engines. This property provides continuous variability valve timing. EMV mechanisms must open the valve and close fast enough to catch the motor speed and in the meantime it must provide reliable valve performance. EMV systems increase of engine performance, reduce specific fuel consumption and emissions of pollutants into the environment in internal combustion engine. In this study, EMV system that can operate with low voltage is mounted on the cylinder head and engine is operated separately with original valve system and electromechanical valve system and are performed of performance and pollutant emissions. 80

Bağımlı değişkenin kategorik olduğu durumda, model parametrelerinin tahmininde kullanılan geleneksel yöntem, En Çok Olabilirlik Tahmin Edicisi (EÇOTE)’dir. Bu yöntemde olabilirlik eşitliklerinin çözümünde, klasik Newton-Raphson (NR) algoritması kullanılmaktadır. Ancak bu algoritma olabilirlik fonksiyonunun diferansiyellenebilir özellikte olduğu durum için uygundur. Bu çalışmada, iki düzeyli bağımlı değişken modellerinde klasik optimizasyon yöntemlerinin uygulanabilmesi için gerekli olan varsayımların sağlandığı durumda optimal parametre tahminlerine ulaşabilmek için NR algoritmasına alternatif olan Genetik Algoritma (GA) yaklaşımının etkinliği araştırılmıştır. Bu amaçla, ilk olarak Alopesia hastalığı verisi kullanılmıştır. Gerçek veri uygulamasına ek olarak yapay bir veri kümesi üzerinden elde edilen sonuçlar da sunulmuştur. Son olarak, yöntemlerin Matlab program kodları ve açıklamaları ayrıntılı bir biçimde verilmiştir. The traditional method in the parameter estimation when we study with a categorical dependent variable is the Maximum Likelihood Estimator (MLE). In this method, the classical Newton-Raphson (NR) algorithm is used in the solution of the obtained likelihood equations. However, this algorithm is suitable when the likelihood function is defferentiable. In this study, the efficiency of the Genetic Algorithm approach (GA), alternative to the NR algorithm, is investigated for obtaining the optimal parameter values when the required assumptions for the classical optimization techniques are satisfied in the binary dependent variable models. For this purpose, first, data related to the Alepecia disease is used. In addition to the real data application, the simulated data results are also presented. Finally, the Matlab commands and their explanations are given in detail.

Materials and Methods: Ninety-eight patients with calcium oxalate kidney stones and 70 controls were enrolled in this study. Five polymorphisms of the VDR gene were studied using the Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) method. Results: For all polymorphisms, genotype frequencies were in line with Hardy-Weinberg equilibrium in the patients and controls. For the BsmI polymorphism, allele frequency distribution was found to differ significantly between the patients and the controls (P

International audience; When annotating complex multimedia data like videos, a human expert usually annotates them manually. However, labeling these immense quantities of videos manually is a labor-intensive and time-consuming process. Therefore, computational methods, such as active learning are used to help annotate. In this study, we propose a cluster based unsupervised active learning approach and a new active learning method for un-supervised active learning on REPERE (Giraudel et al., 2012) video dataset, which is created for the problem of person identification in videos. Our study aims to identify who is speaking and who is on screen by using multi-modal data.

Geri dönüşüm tesislerinde, çeşitli kullanımlar sonrası tehlikeli özelliği kazanmış veya tehlikesiz her türlü metal ve plastik atıklar (polietilen, polipropilen, PVC) gerekiyorsa yıkanmakta, kırılmakta ve sonrasında granül haline getirilmekte ve ara depolanması yapılmaktadır. Malzemelerin nitelik ve niceliklerine göre dışı ve içi su veya solventler kullanılarak yıkanır. Bu çalışmada, tehlikeli atık geri kazanım konularında faaliyet gösteren bir tesiste bidon, varil ve konteyner benzeri ambalajların yıkanması sonucu oluşan atıksuların çeşitli kimyasal yöntemlerle arıtılması amaçlanmıştır. Tesiste 150110 tehlikeli atık koduna sahip kontamine olmuş 1000 L'lik IBC konteyner ve plastik satışı, kontamine olmuş saç varillerin alımı, temizlenmesi ve satışı yapılmaktadır. Çalışmada, bu tesiste çeşitli yıkamalar sonrası çıkan ve dengeleme havuzunda toplanan atıksulardan numune alınarak karakterizasyon, Fenton benzeri, sülfat radikalleri ve foto oksidasyon prosesleri ile KOİ, TOK, TN ve çeşitli ağır metallerin giderim verimleri araştırılmıştır. Debisi 20 m3/gün olan tesisten farklı zamanlarda numuneler alınmıştır. Bu numunelerin KOİ değerleri 4500 mg/L -- 18500 mg/L' arasındadır. Atıksuların karakterizasyonu çalışmasında bu atıksuların çok karmaşık yapıda olduğu ve bu tip atıksuların özelliklerinin yıkanan konteyner veya bidonlar içerisinde taşınan maddelere ve yıkama sırasında kullanılan temizlik maddelerine göre oldukça değişken olduğu görülmüştür. Atıksulardaki organik madde konsantrasyonları (KOİ, BOİ5 ve TOK) oldukça yüksektir. BOİ5/KOİ değerleri 0.18-0.42 arasında değişmektedir. Ağır metal konsantrasyonları da yıkanan bidonların içeriğine ve yıkama prosedürüne göre değişkendir. Karakterizasyon çalışması sonuçları literatürdeki değerlerle uyumludur. Projede bu atıksuların arıtılması için Fenton benzeri prosesi, koagülasyon sonrası, sülfat radikali ve koagülasyon sonrası foto oksidasyon prosesi olmak üzere üç farklı yöntem denenmiştir. Çalışma sonuçlarında organik madde giderimi için üç yöntemin de uygun olduğu ve % 68 –87 arasında KOİ giderimleri elde edildiği görülmüştür. Ayrıca üç yöntemde % 13 – 57 TN, % 32 – 74 TOK ve % 42 – 98 TP giderimi görülmüştür. Fakat bu alternatiflerin, yüksek çamur oluşumu ve yüksek maliyet gibi çeşitli dezavantajları olduğu da mutlaka dikkate alınmalıdır. Bu tesisin atıksu debisi düşük olduğundan maliyet karşılanabilir bir düzeyde ise bu arıtma alternatiflerinin uygulanabilirliği araştırılmalıdır. In recycling plants includes facilities that clean and recondition metal and plastic drums (polyethylene, polypropylene, PVC) for resale, reuse, or disposal. According to quality and quantity of materials exterior and interior of the drums washed using water or solvents. In this study, it is aimed to be treated of wastewater produced from recycling plants with a variety of chemical methods. In the facility sales of 1000 L IBC containers and plastic drums which has hazardous materal code of 150110, buying, cleaning and sales of contaminated steel drums are done. In the facility the wastewater produced from washing of drums and containers are collected in a balnacing tank. In this study, this wastewater was sampled and investigated removal rates of COD, TOC, TN, TP and various heavy metals with, Fenton like treatment, photo oxidation and sulphate radicals. In the study it was sampled different times from the facility which has a flow rate of 20 m3/day. These samples have COD values are between 4500 mg/L -- 18500 mg/L. According to characterization study it was found that these wastewaters had complex quality and the quality of the wastewater depends on the washed materials and/or cleaning solutions. Concentration of organic matter in the wastewater (COD, BOD5 and TOC) was quite high. BOD5 / COD values ranged from 0:18 to 0:42. Heavy metal concentrations were variable depending on the content of the washed drums/containers and washing procedures. The characterization results are consistent with the literature. Three different methods including the process of Fenton Like, photo oxidation and the sulfate radical were tested in the project. The results of the three methods were also suitable for organic matter removal and removal rates were obtained 68% - 87% for COD removal. However, these alternatives should be considered as strong as several disadvantages, such as high sludge formation and high cost. Because this plant wastewater flow is low feasibility of these alternatives should be investigated. Additionally for the treatment of this wastewater, applicabilty of treatment alternatives with urban wastewater treatment plants or after pretreatment giving to urban wastewater treatment plants should be investigated and treatment system should be decided by cost analysis. 92

Aim: In this study we aimed to investigate the thoughts and awareness of community about the effectiveness of the methods about fight against smoking which is applied in our country under '' MPOWER” strategy. Material and Methods: A total of 401 individuals (233 male and 168 female with the age between 19 and 67 year-old) who admitted to Afyon Kocatepe University Hospital for any reason were included in the study. Participants were current smokers or those who use regular cigarettes at least 1 year. A 12-item questionnaire about sociodemographic characteristics and the methods used to fight against smoking were applied to participants with face to face interview technique. Results: While the number of currently smoking individuals who remembered the visual alert on cigarette pack in their pockets were 149 individuals (46%), it was 160 (49%) those remembered the written alert. 203 (50.6%) individuals absolutely agreed, 77 (19.2%) individuals agreed, 12 (3.0%) were undecided, 46 (11.5%) individuals disagreed and 63 (15.7%) individuals strongly disagreed to the question “Do you think smoking ban in closed areas could be effective”. Conclusion: The majority of participants thought that, smoking ban in enclosed areas is effective but they did not believe that, other methods those applied or being considered to practice would not be effective. Based on these results, we believe that prohibitive precautions about fight against smoking should be brought out in our country., Amaç: Biz bu çalışmada ''MPOWER'' kapsamında ülkemizde uygulanan ve uygulanması planlanan sigarayla mücadele yöntemleri hakkında, toplumun farkındalığı ve bu yöntemlerin etkinliği konusunda düşüncelerini araştırmayı amaçladık. Yöntem ve Gereç: Afyon Kocatepe Üniversitesi Hastanesi'ne herhangi bir sebeple müracaat etmiş olan hasta ve hasta yakınlarından, halen sigara içenler ve daha önce en az 1 yıl düzenli sigara kullanmış olan 19 ila 67 yaş arası 168'i kadın 233'ü erkeklerden oluşan, toplam 401 birey çalışmaya dahil edildi. Sosyodemografik özellikler ve sigara ile mücadelede uygulanan politikalara dair 12 soruluk bir anket formu yüz yüze görüşme tekniği ile katılımcılara uygulandı. Bulgular: Halen sigara kullanmakta olup cebindeki sigara paketinin üzerindeki görsel uyarıyı hatırlayan birey sayısı 149 (%46) iken, yazılı uyarıyı hatırlayan birey sayısı 160 (%49) idi. Kapalı alanlarda sigara içme yasağının etkili olabileceğini düşünüyor musunuz sorusuna 203 (%50.6) kişi kesinlikle katılıyorum, 77 (%19.2) kişi katılıyorum, 12 (%3.0) kişi ne katılıyorum ne katılmıyorum, 46 (%11.5) kişi katılmıyorum, 63 (%15.7) kişi kesinlikle katılmıyorum yanıtını verdi. Sonuç: Katılımcılar büyük oranda kapalı alanlarda sigara içme yasağının etkili olabileceğini düşünürken diğer politikaların etkili olmayacağını düşünmektedir. Bu sonuçtan hareketle ülkemizde sigara ile mücadelede yasakçı önlemlerin daha ön plana çıkarılması gerektiği kanaatindeyiz.

Aim: Fertility preservation (FP) has become an important issue for both women and men, due to oncological therapies, gonadotoxic treatments, surgeries, and infertility. The aim of this study is to investigate the publications related to FP, identify the top effective countries and journals, top productive researchers, and trend topics. Material and Methods: The data of this study were obtained using the Thomson Reuters WoS (Thomson Reuters, New York, NY, USA) database, separately for females and males. In the bibliometric analysis, 'fertility preservation' was used as a keyword. VOSviewer (Version 1.6.6) was utilized for bibliometric network visualizations. SPSS was used for the statistical analyses (Version 22.0). Results: Analysis results of the keywords used for men indicated 817 publications and for females indicated 2531 publications totally. The United States of America (USA) was the top country for the publications about both genders. The top three research fields for both genders were Obstetrics and Gynecology, Reproductive Biology, and Oncology. The journals that contributed to the literature most were Fertility and Sterility and Human Reproduction respectively in both gender categories. The correlation between the number of total fertility preservation articles and total cancers, Gross Domestic Product-World Bank (GDP-WB), Gross Domestic Product-International Monetary Fund (GDP-IMF), Human Development Index (HDI), and Internet Users (IU) was significant (r=0.482, p=0.017; r=0.609, p<0.001; r=0.620, p<0.001; r=0.365, p=0.043; r=0.479, p=0.006). Conclusion: It has been determined that researches on the protection of the fertility of cancer patients and infertile patients have increased from past to present.

Objective: This study aims to perform Turkish adaptation of the 30-item new version of the 25-item STARD criteria updated in 2015, which was originally published in 2003 and had to be filled in many international journals while submitting an article with a view to improving the quality of reporting in diagnosis accuracy studies and forming a standard. The study is believed to contribute to the improvements in publication quality of the Turkish publications by forming a standard for diagnosis accuracy. Material and Methods: STARD 2015 criteria were translated to Turkish by three authors separately, and a consensus was reached by giving the final version of each item with YY's guidance. Two doctors who are academicians checked the quality of the 15 diagnosis accuracy draft with a view to evaluating its repeatability level. Agreement among the raters was checked using GWET AC1, Intraclass Correlation Coefficient (ICC) and Bland-Altman methods. Results: GWET AC1 statistics showed that there was a full match between the evaluation results of the 21 criteria. Eight criteria were between 0.81 and 1.00 and 5 criteria were between 0.61 and 0.80. ICC value was found to be 0.871 in the total scores given to the articles by the doctors. Conclusion: It is predicted that in the near future it will be obligatory to fill in the STARD 2015 guide, which became obligatory in many international journals while submitting an article, with a view to increasing the quality of the studies on diagnosis accuracy in the journals in our country.

This research aims to present a bibliometric analysis of the published documents on spirituality, religion and health. Despite the increasing number of publications spirituality, religion and health research in recent years, there is still little information about the effects of these publications in the literature. "Religion," "spirituality," "spiritual," "health" and "medicine" keywords were used to search the Web of Science (WoS) database. Bibliometric analysis was conducted on the articles published between 1975 and 2017. The analysis was presented with network and density maps. The analysis also included the regression analysis to predict a number of publications in 2018. A total number of 1674 publications were found: 818 of these publications were articles. Of the 818 articles, 210 were religion, 198 were Public Environmental Occupational Health, 139 were Psychology, and 77 were performed in the field of Psychiatry. The most productive journal with 107 articles and 1129 citations was the Journal of Religion and Health. The USA (495; 60.5%) was the most productive country on spirituality, religion and health publications. The author who had the highest number of publications and citations was Koenig HG (33 publications; 4.03% and 1617 citations), the document who had the highest number of citations was Ellison CG and Levin JS (633 citations), and the author who had the highest number of citations in the references was Koenig HG, 2001, (126 citations). Duke Univ was the top institution in the number of publication (50 Article). This study will lead the researchers especially in terms of the important journals, active countries, authors, top-cited articles and current topics in spirituality, religion and health research.

Highlights • Industrial container and drum cleaning (ICDC) wastewater characterization was done. • The concentrations of pollutants in ICDC wastewater have very variable structure. • Fenton-like process and combined coagulation/oxidation processes have been studied. • All methods were suitable for the removal of COD, BOD, TOC, TP, and of some metals. • Fenton-like process is a favorable system for modification of existing system. Abstract Industrial container and drum cleaning (ICDC) facilities generated complex wastewater which have organic/inorganic compounds, acids, alkalis, metals, dyes, asbestos, PCBs, chemical cleaning solutions or textile auxiliary chemicals. Treatment of such these wastewaters containing all these pollutants is also very difficult. It is required that the wastewater chemical oxygen demand (COD) is below 1500 mg/L to treat in a centralized wastewater treatment facility in Thrace Region, Turkey. In this study the characterization of ICDC industrial wastewater and treatment alternatives of this wastewater using Fenton-like (FL) process, acidic coagulation-flocculation + H 2 O 2 /UV-C (CF + H 2 O 2 /UV-C) and acidic coagulation-flocculation + S 2 O 8 2− (CF + S 2 O 8 2−) processes have been studied. The existing treatment system already has a biological treatment system after coagulation-flocculation system and couldn't be operated effectively in spite of all the efforts. We have studied processes that can be integrated into the coagulation-flocculation (CF) process used in the existing wastewater treatment plant. According to characterization study, COD values were in the range of 4584–18125 mg/L. The COD of the wastewater used in treatment experiments were 11,853 mg/L. According to the results FL and CF + S 2 O 8 2− systems were suitable for the COD discharge standards specified for the centralized wastewater treatment plant. The optimum conditions of FL process were 0.8 g/L for FeCl 3 and 45 g/L for H 2 O 2 and COD was measured as about 1500 mg/L at these doses. The optimum conditions of CF + S 2 O 8 2− system were determined as 0.64 g/L FeCl 3 for CF and 15 g/L H 2 O 2 doses. At these dosages the highest COD removal efficiency was achieved to 68% after 5 h. All methods used were suitable for the removal of COD, biochemical oxygen demand (BOD), total organic carbon (TOC), total phosphorus (TP) and of some metals. Considering the integration into the existing treatment system and applicability, it is concluded that the FL process is most favorable. [ABSTRACT FROM AUTHOR]

Objective: We aimed to determine nutritional status and related factors among schoolchildren in Çorum, Central Anatolia, Turkey.Design: Schoolchildren's height and weight were measured to calculate BMI and BMI Z-scores. Height, weight and BMI Z-scores were analysed and nutritional status classified according to the WHO.Setting: Central Anatolia, Turkey.ParticipantsSchoolchildren aged 5-17 years (n 1684) participated in study.Results: Of children, 4·2% were stunted, 6·9% thin, 13·8% overweight and 6·6% were obese. Proportions of stunting, thinness and overweight/obesity were significantly higher in children aged >10 years (78·6, 75·0 and 64·9%, respectively) than in those aged ≤10 years (21·4, 25·0 and 35·1%, respectively; all P <0·001). Median (range) birth weight and breast-feeding duration in children with stunting (2750 (1400-3600)g; 10 (0-36) months) were significantly lower and shorter, respectively, than those of normal height (3200 (750-5500)g; 15 (0-72) months) and tall children (3500 (2500-4900)g; 18 (0-36) months; P <0·001, <0·001, 0·011 and 0·016, respectively). The same relationship was observed in thin children (3000 (1000-4500)g; 12 (0-36) months) compared with normal-weight (3200 (750-5500)g; 15 (0-72) months) and overweight/obese children (3300 (1200-5500)g; 16 (0-48) months; P=0·026, <0·001, 0·045 and 0·011, respectively).Conclusions: Overweight and obesity are health problems that must be addressed in schoolchildren. Adolescents also have a risk of double malnutrition. Promoting normal birth weight and encouraging long duration of breast-feeding are important to support normal growth in children.

RESPIRATORY infections ,SURGICAL complications ,OBSTRUCTIVE lung diseases ,PREOPERATIVE period - Abstract
OBJECTIVE: We aimed to determine the preoperative parameters that may predict postoperative pulmonary complications (POPCs) and the value of some current practical indexes in predicting POPCs. MATERIALS and METHODS: Our study is a retrospective cohort study carried out in 9 different centers. Patients admitted to the chest diseases outpatient clinic for preoperative evaluation were followed up during the 6-month study period. Patients with or without postoperative complications were evaluated retrospectively, and the effect of some parameters and indexes recorded during the preoperative evaluation of chest diseases on POPC development was investigated statistically. RESULTS: A total of 307 patients were included in the study. POPCs were observed in 100 patients (32.6%). About 13% of these complications were respiratory tract infections, 59% were respiratory failure, 45% were pleural effusion, and 42% were atelectasis, which were the most common pulmonary complications. The probability of experiencing POPCs by patients with chronic obstructive pulmonary disease (COPD) is 2.5 (1.18–5.67) times more than those without COPD. We determined that patients with the history of upper respiratory tract infection during the preoperative period are 5.3 times more likely to have POPCs; similarly, the number was 4.7 for patients undergoing cardiac operation and 3.3 for patients with interstitial infiltration. CONCLUSION: The risk of pulmonary complications was higher for those with the history of upper respiratory tract infection during the preoperative period, those undergoing cardiac surgery, those with the shortness of breath, those with the history of COPD, and those with the reticular/interstitial infiltrations in the chest X-ray. These parameters should be examined carefully in the preoperative period and should be careful in terms of pulmonary complications that may develop during the postoperative period.

İstatistik ,Statistics - Abstract
Bağımlı ve açıklayıcı değişken (ler) arasındaki ilişkinin araştırılması için yaygın olarak kullanılan doğrusal regresyon analizi, bağımlı değişkenin iki ya da daha fazla düzey içeren kategorik bir değişken olması durumunda bazı istatistiksel varsayım bozulumlarından dolayı kullanılamamaktadır. Bu durumda doğrusal regresyona alternatif bazı doğrusal olmayan modeller önerilmiştir. Lojistik Regresyon Modelleri bu alternatif modeller arasında en fazla tercih edilen modeller olmuştur. Bu modellerde parametre tahminleri genellikle geleneksel En Çok Olabilirlik, Yeniden Ağırlıklandırılmış İteratif En Küçük Kareler Yöntemi ve Minimum Logit Ki-Kare Yöntemi ile yapılmaktadır. Bu yöntemlerde en iyi parametre tahminlerine ulaşabilmek için gradyant optimizasyon tekniklerinden yararlanılır. Oysaki optimize edilmeye çalışılan fonksiyon her zaman türevlenebilir özellikte olmayabilir. Bu durumda, fonksiyonların sürekli (dolayısıyla türevlenebilir) olmasını gerektirmeyen alternatif optimizasyon tekniklerinin de bilinmesi gerekmektedir. Yapılan çalışmalar, bağımlı değişkenin sürekli olması durumunda Genetik Algoritma Yaklaşımının parametre tahminlerinde başarılı bir biçimde uygulandığını ortaya çıkarmıştır. Bağımlı değişkenin kategorik olduğu modeller dikkate alındığında, parametrelerin etkin tahminlerine ulaşabilmek için Genetik Algoritma yaklaşımı kullanılarak yapılmış yeterli sayıda çalışmaya rastlanmamıştır. Bu çalışmada, bağımlı değişkenin kategorik olması durumunda parametrelerin tahmin edilmesinde bazı sezgisel optimizasyon yöntemlerinin etkinliği araştırılmıştır. Genetik Algoritmaya ek olarak Nelder-Mead Algoritması da ayrıntıları ile incelenmiştir. Lojistik regresyon analizinde klasik Newton-Raphson tahminleri, Genetik Algoritma ve Nelder-Mead tahminleri ile karşılaştırılmıştır. Son olarak, kategorik bağımlı değişken modellerinde Genetik Algoritma ve Nelder-Mead optimizasyon tekniklerinin kullanılabilirliği gösterilmiş ve tahminlerin Matlab kodları tanıtılmıştır. Linear Regression Analysis which is widely used for examining the relationship between the dependent and explanatory variables could not be used because of some assumptions violations when the dependent variable is categorical with two or more levels. In such a case, some nonlinear models as alternatives to the linear regression have been proposed. Logistic Regression Models are most preferred models among all the alternatives. In these models, parameter estimation is generally made by the conventional methods of Maximum Likelihood, Iteratively Reweighted Least Squares Method and Minimum Logit Chi-Square Method. These methods require gradient optimization techniques to reach efficient parameter estimations. However, the objective function to be optimized does not have differentiable structure at all times. In this case, alternative optimization techniques should be known, which do not require the continuousness (so differentiability) of the function. Studies made in this field have brought to light that the Genetic Algorithm Approach to the parameter estimation has been successfully applied when the dependent variable is continuous. Taking into consideration of the categorical structure of the dependent variable, it has been realised that there is no adequate number of research made for obtaining efficient parameter estimation via the Genetic Algorithm approach. In this study, efficiency of some heuristic optimization techniques in the parameter estimation has been examined in case of the categorical dependent variable models. In addition to the Genetic Algorithm, the use of the Nelder-Mead algorithm has also been analyzed, in detail. The classical Newton-Raphson estimations have been compared with the Genetic Algorithm and Nelder-Mead estimations. Finally, the applicability of the concerned optimization techniques in categorical dependent variable models has been shown and Matlab commands of the estimations have been introduced. 118

In this study, we mainly dealt with the introduction and comparison of two optimization techniques over the estimated parameters and model results of the Binary Logistic Regression (LR) model. These are the traditional Newton-Raphson (NR) algorithm which requires the differentiable objective function and appropriate starting values related to the parameters and Genetic Algorithm (GA) approach which does not need any strict assumptions as the algorithm NR. The results suggest that NR algorithm and GA give very similar results when the assumptions of NR are satisfied. This indicates that GA could successfully be used instead of the NR method considering its more flexible assumptions. Moreover, if the objective function does not satisfy the differentiability condition, NR could not be used in the optimization process and fails to find the optimum values. Therefore, this study actually reveals the success of GA in the parameter estimation of LR model. All the model outputs are compared in terms of the estimated parameter values, ease of application and convergence rates. Matlab commands are also given with their explanations for GA for researchers studying in this area.

The basic aim of this study is to calculate relative efficiency of high schools in Çorum in 2012-2013 academic year by means of Data Envelopment Analysis and to contribute the effectiveness and productiveness of the high schools. In the study, Charnes-Cooper-Rhodes (CCR) Model (1978) which has constant outcomes as per the scale and, Banker- CharnesCooper (BCC) Model (1984) which has variable outcomes as per the scale have been used according to the input. For measurement of effectiveness, the numbers of the students registered, teachers and classes at the high schools have been determined as the three input data and; success rates from Higher Education Examination-Undergraduate Placement Examination (YGSLYS), YGS point averages, points from LYS Math-Science, Turkish-Math, Turkish-Social sciences have been determined as the five output data. As a result of the analyses, four schools have been found effective according to CCR model and nine schools have been found effective according to BCC model. It has been found that productivity scores of the rest of the high schools are low and these schools have not worked effectively. According to the results of the analyses, certain recommendations have been noted in order to improve educational qualities in accordance with inputs and outputs which are necessary to be changed, Bu çalışmanın temel amacı Çorum ilindeki liselerin 2012-2013 eğitim-öğretim sürecindeki göreli etkinliklerinin Veri Zarflama Analizi (VZA) tekniği ile hesaplanması ve elde edilen bulgular sonucunda okulların etkinliğini ve verimliliğini arttırmalarına katkıda bulunmaktır. Çalışmada girdiye yönelik ölçeğe göre sabit getirili Charnes-Cooper-Rhodes (CCR) Modeli (1978) ve ölçeğe göre değişken getirili Banker- Charnes-Cooper (BCC) Modeli (1984) kullanılmıştır. Etkinlik ölçümü için okullardaki öğrenci sayısı, öğretmen sayısı ve şube sayısından oluşmak üzere üç adet girdi ve Yüksek Öğretime Geçiş Sınavı (YGS) - Lisans Yerleştirme Sınavı (LYS) başarı (yerleştirme) oranı, YGS puan ortalamaları, LYS Matematik-Fen, Türkçe-Matematik, Türkçe-Sosyal bilimler puanları olmak üzere beş adet çıktı belirlenmiştir. Yapılan analiz sonucunda; CCR modeline göre dört okul etkin BCC modeline göre ise dokuz okul etkin çıkmıştır. Diğer liselerin verimlilik skorlarının daha düşük olduğu ve etkin çalışmadıkları tespit edilmiştir. Okullar için yapılan analiz sonuçlarına göre eğitim-öğretim kalitesinin arttırılması amacıyla hangi girdi ya da çıktının ne derece ve ne yönde değiştirilmesi gerektiği konusunda karar verme birimlerine önerilerde bulunulmuştur.
