Metadata that means data about data enables the discovery of such information. When the metadata is effectively used, it increases the usefulness of the original data/resource and facilitates the resource discovery. Resource Description Framework (RDF) is a basis for handling these metadata and is a graph-based, self-describing data format that represents information about web-based resources. It is necessary to store the data persistently for many Semantic Web applications that were developed on RDF to perform effective queries. Because of the difficulty of storing and querying RDF data, several storage techniques have been proposed for these tasks. In this paper, we present the motivations for using the RDF data model. Several storage techniques are discussed along with the methods for optimizing the queries for RDF datasets. We present the differences between the Relational Database and the XML technology. Additionally, we specify some of the use cases for RDF. Our findings will shed light on the current achievements in RDF research by comparing the different methodologies for storage and optimization proposed so far, thus identifying further research areas.
Mobil Tabanlı Optik Form Değerlendirme Sistemi

Optik formlar optik okuyucu cihazlar sayesinde optik işaret tanıma teknikleri kullanılarak değerlendirilmektedir. Bu tip cihazların pahalı olması, bu cihazlara erişimin sınırlı olması ve değerlendirme sonuçlarını bekleme süresinin uzun olması hem büyük şehirlerde hem de taşrada çalışan eğitimcilere zorluk çıkarmaktadır. Bu çalışmada eğitimcilerin sahip oldukları akıllı telefon ya da tabletleri aracılığı ile bir mekana ya da optik cihaza bağlı kalmadan, hızlı bir şekilde öğrenci cevap formlarını değerlendirebilecekleri mobil bir yazılım geliştirilmiştir. Optik form tanıma, okuma ve değerlendirme işlemi eğitimcinin mobil telefonu ya da tableti aracılığı ile çektiği öğrencinin cevap formu görüntüsü üzerinde yapılmaktadır. Geliştirdiğimiz Android tabanlı mobil uygulama kullanıcı dostu bir arayüze ...

Hierarchical multiple linear regression results showed that integrity and relationship dimensions of mentoring roles displayed by teaching staff have a significant effect on social loneliness levels of
An Example Application of an Artificial Intelligence-Supported Blended Learning Education Program in Computer Engineering

Integration of face-to-face and online learning with blending learning can enhance the learning experience and optimize seat time. In this chapter, the authors present the teaching of an Algorithm and Programming course in Computer Engineering Education via an artificial intelligencesupported blended learning approach. Since 2011, Computer Engineering education in Suleyman Demirel University Computer Engineering Department is taught with a blended learning method. Blended learning is achieved through a Learning Management System (LMS) by using distance education technology. The LMS is comprised of course materials supported with flash animations, student records, user roles, and evaluation systems such as surveys and quizzes that meet SCORM standards. In this chapter, the related education process has been supported with an intelligent program, which is based on teaching C programming language. In this way, it has been aimed to improve educational processes within the related course and the education approach in the department. The blended learning approach has been evaluated by the authors, and the obtained results show that the introduced artificial intelligencesupported blended learning education program enables both teachers and students to experience better educational processes.

In this paper, we present the teaching of Algorithm and Programming course in Computer Engineering Education via blended learning approach. Since 2011, Computer Engineering education in Süleyman Demirel University Computer Engineering Department is taught with blended learning method. Blended learning is achieved through Learning Management System (LMS) of university by using distance education technology. LMS comprises of course materials supported with flash animations, student records, user roles, evaluation system such as surveys and quizzes that meet SCORM standards. In this paper, performance evaluation of students in traditional and blended education for Computer Engineering is provided. Applied blended learning model is presented and evaluation of students who are taking programming courses is done. Therefore, it is aimed that adaptation period of students in blended education is shortened. Our results show that algorithmic thinking abilities of students who enrolled in the Algorithm and Programming course in blended and traditional education are close.

The study group comprises preservice teachers who were senior year students at the Firat University Education Faculty in Elazi city, Turkey during the spring term of 2009 2010 academic year. Cyber bullying of preservice teachers directly impacts their distrust levels at the 0.24 level. However, when internet addiction was included in the model as a mediating variable, the direct impact of cyber bullying on distrust decreased to 0.14. Therefore, it is evident that when cyber bullying is mediated by internet addiction, its impact on the distrust levels of preservice teachers is more significant.
Öğretmenlerin Maruz Kaldıkları Psikolojik Şiddete İlişkin Bir Modelin Sınanması (Examining a Model related to Mobbing Incurred by Teachers)

Araştırmanın çalışma evrenini, Elazığ il merkezinde 2008–2009 güz döneminde çalışmakta olan ilköğretim öğretmenleri oluşturmaktadır. Anketler, bu çalışma evreninden seçkisiz olarak seçilmiş olan 300 kişilik örneklem grubuna uygulanmış ve bu anketlerden 237 tanesi geçerli sayılarak analize dâhil edilmiştir. LISREL 8.51 versiyonu kullanılarak bir yapısal eşitlik modeli geliştirilmiştir. Bu modele göre psikolojik şiddet, stres ve tükenmişliği pozitif şekilde, iş ve yaşam doyumunu ise negatif şekilde etkilemektedir. Psikolojik şiddet; stresin kısmi aracılık etkisiyle tükenmişliği, stres ve tükenmişliğin kısmi aracılık etkileriyle iş doyumunu ve son olarak da stres, tükenmişlik ve iş doyumunun kısmi aracılık etkileriyle yaşam doyumunu etkilemektedir. Anahtar sözcükler: Psikolojik şiddet, stres...
