    Predicting factors affecting PISA 2015 mathematics literacy via radial basis function artificial neural network
    (Batman Üniversitesi, 2019-05-23) Güre Bezek, Özlem; Kayri, Murat; Erdoğan, Fevzi
    In this study, radial basis function artificial neural network (RBFN), which is one of the of data mining methods, was employed to determine the factors affecting PISA 2015 (Programme for International Student Assessment - PISA), Mathematics literacy. Mathematics literacy scores, which were made in categorical form with three level dependent variables, 25 independent variables, and considered to have affected the dependent variables, were employed in evaluating and validating the proposed method. Also, in order to determine factors affecting PISA 2015 Mathematics literacy, information obtained from a total of 4422 students (2165 (49%) of whom were males and 2257 (51%) of whom were females) who participated the exam was used. According to the obtained results, the correct classification rate of mathematics achievement in the radial based artificial neural network model was found to be 85.2%. In addition, it is seen that the most important factor that were affecting Mathematics literacy was Turkish language success status and the other variables that were setting significance are targeted point in school life, father education level and mother education level.

    Benzoil ester grubu içeren 2,4-dinitrofenilhidrazin temelli bazı yeni hidrazon bileşiklerinin sentezi ve yapısal karakterizasyonu
    (Batman Üniversitesi, 2022-06-30) Çakmak, Reşit; Başaran, Eyüp
    Hidrazon bileşikleri, ilaç tasarımı çalışmalarında aday bileşikleri elde etmek için kullanılan önemli öncülerdir. Bu çalışmada, başlangıç materyali olarak 4-(dietilamino) salisilaldehitten türetilen benzoil ester türevleri (1-5) sübstitüe benzoil klorür türevleri (benzoil klorür, 2-nitrobenzoil klorür, 3-nitrobenzoil klorür, 4-nitrobenzoil klorür ve 3,5-dinitrobenzoil klorür) ile çözücü olarak piridin ortamında 1:1 mol oranında reaksiyona girmesiyle sentezlendi. Elde edilen benzoil esterler ile 2,4-dinitrofenilhidrazinin kondenzasyon reaksiyonu ile yeni bir dizi hidrazon bileşikleri (6-10) sentezlendi ve bu bileşikler yapısal karakterizasyonu FT-IR, 1H NMR, 13C NMR ve element analizi aydınlatıldı. Sonuç olarak, bu bileşiklerin biyolojik aktiviteler gösterebileceği düşünülmektedir.

    The methods used in histopathological evaluation of testis tissues
    (Batman Üniversitesi, 2020-06-30) Yalçın, Tuba; Kaya, Sercan; Kaya Tektemur, Nalan; Ozan, İ. Enver
    The quantitative measurements are numerical data as the outputs of various processes. Statistical analysis is employed to the collected data. Results obtained from the statistical data are considered as more reliable. Therefore, measurement processes are the basis of research sciences today. Histology is a discipline that examines the microscopic structure of cells and tissues. Morphometric measurements can be performed on cell and tissue samples through electron and light microscope. In the PubMed search engine, MEDLINE, SCIENCE DIRECT and Web of Science, Springer Link, and Ovid were scanned for the words “Testis, histopathology, quantitative, seminiferous tubule”. The findings obtained through these qualitative methods provide interpretation of the changes in tissue morphology. These assessments allow researchers to identify the tissue samples and to compare the physiological variations in its morphology. In histology, the results obtained from routine dyeing of laboratory studies are qualitative, therefore, relative differences may emerge in the interpretation of the results. In order to eliminate this risk, various quantitative measurement methods are implemented. Today, in order to employ accurate evaluations, the histometric and stereological measurement methods that are used in organs such as testicles, liver, lung, and kidney gain importance. The quantitative data obtained from these transactions is sufficient for statistical analysis. It is also important to reach a certain standardization level in the repetition of qualitative or semi-quantitative data obtained during the statistical analyses. The aim of this study is to summarize the methods used in histopathological evaluation of testicular tissues.
