The factors that affect plasma homocysteine levels, pulse wave velocity and their relationship with cardiovascular disease indicators in peritoneal dialysis patients

Objective The incidence of cardiovascular diseases (CVD) is high in end-stage renal disease (ESRD) population and hyperhomocysteinemia is an important CVD risk factor. The aims of this study are to asses the incidence of hyperhomocysteinemia and the factors that affect the homocysteine (Hcy) levels in peritoneal dialysis (PD) patients, and to analyze the relationships between Hcy levels and clinical and echocardiographic CVD, and the pulse wave velocity (PWV). Study design Sixty ESRD patients undergoing PD for at least 6 months were included in the study. Biochemical parameters, echocardiography, and PWV were analysed for every subject. Results Mean Hcy level was 27.2 ± 15.7 lmol/L and was high in 53 patients (88.3%). Fibrinogen, dialysate/plasma creatinine ratio and folic acid were found to be the independent predictors of Hcy level (P\0.001; P\0.01; P\0.05, respectively). Patients with atherosclerosis had significantly higher plasma Hcy levels (P\0.05). No significant relationship was found between plasma Hcy levels and echocardiographic findings and PWV. Conclusion Hyperhomocysteinemia incidence seems high among PD patients and despite significant relationship between fibrinogen and Hcy in our study, it is essential to evaluate the link between Hcy levels and inflammation. Folic acid replacement even in normal folic acid levels, enough elimination of volume and solutesmay be beneficial to control Hcy levels, whereas PWV was found to be related with comorbidities and and dialysate kinetics

RELATIVE EFFICIENCY ANALYSIS OF BLACK SEA CONTAINER TERMINALS

Dünyada yük taşımacılığı en fazla denizyolu ile yapılmaktadır. Denizyolu taşımacılığı içerisinde konteyner taşımacılığının oranı sürekli artış göstermektedir. Diğer denizyolu taşımacılık sistemlerinde olduğu gibi konteyner taşımacılığında da limanlar arasında yoğun bir rekabet vardır. Bu nedenle limanların bu yoğun rekabet ortamında faaliyet gösterebilmeleri için, yapılan işin doğası gereği sadece ulusal değil uluslararası standartlarda iş yapabilmeleri ve uluslararası geçerliliği olan performans göstergelerine sahip olmaları gereklidir. Bu çalışmada; Karadeniz çevresinde konteyner taşımacılığına hizmet veren ve TRACECA programı çerçevesinde Karadeniz'de faaliyet gösteren 5 ülke (Türkiye, Gürcistan, Ukrayna, BulgaristanveRomanya) ve program dışında bulunan Rusya'ya ait toplam 9 konteyner terminali (Novorossisk, Odesa, Varna, Burgaz, Batum, Poti, Ilyichevsk, Köstenceve Trabzon) 2011 yıl göreceli etkinlikleri parametrik olmayan Veri Zarflama Analizi (VZA) uygulaması ile belirlenmiştir. VZA sonuçlarına göre, incelenen terminaller içerisinde Poti ve Novorossisk konteyner terminali göreceli etkin durumdadır. Diğer yandan, en düşük göreceli etkinliğe sahip olan terminal ise Burgaz konteyner terminalidir Most of the world's freight transportation is made by maritime transportation. The proportion of container transportation within maritime transportation shows a constant increase. As it is the case for other maritime transportation systems, also in container transportation there is an intense competition among ports. For that matter, it is essential for the ports to have the internationally acceptable minimum performance indicators and to be capable of performing not only at national, but also at international standards by the nature of the work done, in order to continue operation under such intense competition conditions. In this study, the year performance, 2011 of nine container terminals (Novorossiysk, Odessa, Varna, Burgas, Batumi, Poti, Ilyichevsk, Constanta and Trabzon) belonging to a total of six countries with coastlines to the Black Sea, which is the largest inland sea, as five countries from the TRACECA (Transport Corridor Europe-Caucasus-Asia) program (Turkey, Georgia, Ukraine, Bulgaria and Romania) and Russia out of the program, have been determined through the application of data envelopment analysis (DEA), as a non-parametric method. According to the results of the study, it has been determined that the Poti and Novorossiysk container terminals have been the efficient terminals. On the other hand, Burgas container terminal has been found out to be the terminal with the lowest performance

Elde edilen veriler SPSS 11.5.0 istatistik programı ile çözümlenmiştir. Verilerin çözümlenmesinde; frekans, yüzde, aritmetik ortalama, standart sapma, bağımsız gruplar t-testi, ANOVA varyans analizi, Levene Statistic homojenlik testi, Post Hoc Tukey HSD ve Post Hoc Tamhane’s T2 çoklu karşılaştırma analizi tekniklerinden faydalanılmıştır.Araştırma sonucunda meslek lisesi öğrencilerinin daha çok okul ana binasında, ayda bir veya üç ayda bir nöbet tuttuğu tespit edilmiştir. Bunun dışında, öğrencilere ait cinsiyet, sınıf, okul türü, alan türü, nöbet yeri ve nöbet sıklığı değişkenlerinin tümünde; nöbet sisteminin öğrenci başarısına etkisi hakkındaki öğrenci görüşüne ilişkin anlamlı farklılıklar bulunmuştur. Araştırmanın son bölümünde sonuçların tümü sunulmuş ve bu sonuçlara dair iyileştirici önerilerde bulunulmuştur. ABSTRACTOPINION OF THE STUDENTS ABOUT THE EFFECT OF THE GUARD DUTY SYSTEM IN VOCATIONAL HIGH SCHOOLS ON THE STUDENT SUCCESSThis research was conducted to discover the opinion of the students about the level of the effect of the guard duty system in vacational high schools on the student success and to advance helpful proposals. The information about the location, frequency and characteristic of the guard dury was tried to discover by the help of this research.Field study model was used in this research. The sample group consisted of 418 students from 8 different high schools which were affiliated to General Directorate of Male Student Technical Education in Anatolian side of Istanbul.A two-part survey sheet was prepared to collect the data.
