    In this study, South Korea, Singapore, Japan, Finland and Turkey Countries teachers and school administrators were compared in terms of assignment policies. In this research, a holistic multiple state pattern, which is one of the qualitative research types, was used. The reason for using this method has been examined in accordance with the problem situation of these countries and then compared with each other. The appointment policies of teachers and school administrators should be evaluated along with other processes. South Korea, Singapore, Japan, Finland countries excelled in PISA 2003, 2006, 2009 and 2012 exams. The selection of qualified teachers and school administrators plays an important role in this success of these countries.While choosing candidates for education faculties in these countries, exams measure their teaching skills via central exams. In the process of assigning teachers, central exams are conducted, but institutions again conduct exams that measure their teaching skills. Teaching appeal is a profession in these countries. Because in these countries, teaching has all the features such as respectability, high status, job guarantee and high salary. Teacher salaries in these countries are above the average of OECD countries. In addition, great importance is attached to the in-service training of school administrators and teachers in these countries. The salaries of teachers in Turkey is below the average of OECD countries

    Multi-Label Noise Robust Collaborative Learning Model for Remote Sensing Image Classification

    The development of accurate methods for multi-label classification (MLC) of remote sensing (RS) images is one of the most important research topics in RS. Methods based on Deep Convolutional Neural Networks (CNNs) have shown strong performance gains in RS MLC problems. However, CNN-based methods usually require a high number of reliable training images annotated by multiple land-cover class labels. Collecting such data is time-consuming and costly. To address this problem, the publicly available thematic products, which can include noisy labels, can be used to annotate RS images with zero-labeling cost. However, multi-label noise (which can be associated with wrong and missing label annotations) can distort the learning process of the MLC algorithm. The detection and correction of label noise are challenging tasks, especially in a multi-label scenario, where each image can be associated with more than one label. To address this problem, we propose a novel noise robust collaborative multi-label learning (RCML) method to alleviate the adverse effects of multi-label noise during the training phase of the CNN model. RCML identifies, ranks and excludes noisy multi-labels in RS images based on three main modules: 1) discrepancy module; 2) group lasso module; and 3) swap module. The discrepancy module ensures that the two networks learn diverse features, while producing the same predictions. The task of the group lasso module is to detect the potentially noisy labels assigned to the multi-labeled training images, while the swap module task is devoted to exchanging the ranking information between two networks. Unlike existing methods that make assumptions about the noise distribution, our proposed RCML does not make any prior assumption about the type of noise in the training set.

    This study aimed to determine the direct and indirect effects of the independent variables presented by the lactation length (LL), age of calving (CAGE), and daily milk yield (DMY) on the dependent variable of lactation milk yield (LMY) in Anatolian buffaloes. In this study, 3761 LMY records of the 834 Anatolian buffaloes calving between 2012 and 2017 in Tokat province and around were used as the research material. In the study, the simple correlation coefficients between the dependent variable of LMY and independent variables were determined to be positive and significant (P[removed

    Bu araştırmanın amacı, turizm eğitimi alan lisans ve ön lisans öğrencilerinin girişimci kişilik özelliklerinin tespit edilmesidir. Bu amaçla, Sakarya Üniversitesi ve Abant İzzet Baysal Üniversitesi’nde turizm eğitimi alan 308 lisans ve ön lisans öğrencisi üzerinde bir alan araştırması gerçekleştirilmiştir. Araştırmadan elde edilen veriler istatistiki metotlarla analiz edilmiştir. Araştırma sonucu elde edilen bulgular, turizm öğrencilerinin girişimci kişilik özelliklerine önemli ölçüde sahip olduklarını göstermiştir. Ayrıca, girişimci kişilik özellikleri bakımından lisans ve ön lisans öğrencileri arasında anlamlı bir farklılık olduğu tespit edilmiştir.Aim of this study is to determine entrepreneurial personality traits of associate and bachelor’s degree tourism students. For this purpose, an empirical research was carried out on undergraduate 308 tourism students that studying at Sakarya University and Abant Dzzet Baysal University. Obtained data from the research was analyzed by statistical methods. Results of this research indicated that undergraduate tourism students dramatically have entrepreneurial personality traits. However, at the conclusion of the research it was determined that there was significant difference between associate and bachelor’s degree tourism students’ entrepreneurial personality traits

    Objective: The aim of this study was to investigate therole of tympanogram test in routine use comparing thetympanogram findings and otoscopic examination findingsin patients with suspicious otitis media with effusion.Materials and methods: 64 outpatients with suspiciousotitis media with effusion presented at our Otorhinolaryngologyclinic and first otoscopic examination and thentympanometric examination was performed for their 128ears. Predictions of the physicians who performed otoscopicexamination for outcomes from tympanogram andactual tympanogram outcomes were compared.Results: Predictions of the physician for otoscopic examinationwere different from tympanogram outcomesin 22.6 percent (n=29) of 128 otoscopic examinationsin total. However, the physician predicted Type A tympanogramsuggesting no effusion in only four of theseotoscopic examinations yet Type B or Type C outcomessuggesting existence of effusion were obtained from tympanogram.Conclusion: Application of tympanogram test routinelyas part of otologic examination to each patient is a causeof material loss. Our first choice should be otoscopic examination.Key words: Otitis media with effusion, tympanogram,otoscop
