    In this research, it was aimed to reveal the knowledge and opinions about play in pre-school teachers' mathematics educational process. The research was designed as a mixed method. The qualitative dimension of the study included the analysis and interpretation of the data obtained through a semi-structured interview form. The quantitative dimension of the research was composed of statistical analysis of the data collected by means of “Pre-school Mathematics and Play Scale’’ according to various variables. In the analysis of the data obtained from the scale in the study, one-way ANOVA was used for unrelated samples and t-Test for unrelated samples. The data obtained from semi-structured interview form were analysed using content analysis technique. It was found in the research that the pre-school teachers emphasized the play to be an effective tool in achieving concretization in mathematical teaching and supporting the activities so as to meet the children's entertainment needs. However, teachers stated that they had difficulty in finding and using plays on various topics of mathematics. Teachers were seen not to be able to distinguish between play and activity.

    Toplumun rasyonel yetileriyle belirlenen öznelere atıfla öznelerarası bir etkileşim düzeni olarak düşünülmesi mümkün müdür? Böyle bir şey olgusal açıdan mümkün ve normatif açıdan savunulabilir ise bunun koşulu, özgürleşim ile muhakeme arasında zorunlu bağ varsayan bir insan ve toplum görüşü benimsemektir. Bu varsayım öznelerin muhakeme yetisini konuşma veya yazı aracılığıyla öznelerarası bir rasyonel müzakerenin parçası kılmasını gerektirir. Bu konu kamusallık ile geleneksel medya arasındaki ilişkiye işaret eder. Bu iki olgu arasında nedensel bir ilişki olup olmadığı tartışmalıdır; fakat ikilinin modern sekülerliğin doğuşuyla ilgili olduğu konusunda fikir birliğinden söz edilebilir. Konunun önemi günümüzde hemen hemen aynı bağlamda hala gündemde olmasından kaynaklanır. Postseküler toplum tartışması bağlamında müzakereci demokrasi ile yeni medya ortamlarının kamusal niteliği arasındaki tartışma örnek verilebilir. Bu nedenle çalışmada, literatürde eksikliği hissedilen, metateorik düzey ve buna uygun bir yöntem belirlenmiştir. Bunun için (i) kamusallık ile kitap arasındaki ilişkiyi Habermas’ın Kamusallığın Yapısal Dönüşümü isimli ve alanda klasik haline gelmiş çalışmasıyla ilişkilendirmeye, (ii) kitabın kamusal işlevleri açısından içerikçe çeşitlenen bir resim elde etmeye çalışacağız. Habermas kamusallık ile kitap ilişkisini rasyonel müzakere zemininde dikkate aldığında, burjuva kamusallığı modelinde kültürel akıl üreten okuma faaliyetinin önemini ve tüketim kültürüne dayalı okumanın devlet ile toplum arasındaki olumlu ayrımı giderdiğini vurgular

    Random forest-based landslide susceptibility mapping in coastal regions of Artvin, Turkey

    Natural disasters such as landslides often occur in the Eastern Black Sea region of Turkey owing to its geological, topographical, and climatic characteristics. Landslide events occur nearly every year in the Arhavi, Hopa, and Kemalpa¸sa districts located on the Black Sea coast in the Artvin province. In this study, the landslide susceptibility map of the Arhavi, Hopa, and Kemalpa¸sa districts was produced using the random forest (RF) model, which is widely used in the literature and yields more accurate results compared with other machine learning techniques. A total of 10 landslide-conditioning factors were considered for the susceptibility analysis, i.e., lithology, land cover, slope, aspect, elevation, curvature, topographic wetness index, and distances from faults, drainage networks, and roads. Furthermore, 70% of the landslides on the landslide inventory map were used for training, and the remaining 30% were used for validation. The RF-based model was validated using the area under the receiver operating characteristic (ROC) curve. Evaluation results indicated that the success and prediction rates of the model were 98.3% and 97.7%, respectively. Moreover, it was determined that incorrect land-use decisions, such as transforming forest areas into tea and hazelnut cultivation areas, induce the occurrence of landslides.Funding: This research was supported by the Scientific Research Projects Office of Artvin Çoruh University (AÇÜBAP) (Scientific Research Project No. 2016.F40.02.05)

    Implementation of a web services-based SDI to control and manage private ownership rights on coastal areas

    Get PDF
    It is stated in the legislation related to the management of coastal areas, particularly in the Coastal Law, that private ownership shall not be allowed in coastal areas in Turkey. However, due to de?ciencies in the legislation, insuf?ciencies in control and enforcement, and, most importantly, lack of interoperability among institutions, it is evident that private ownership exists in coastal areas. According to the Coastal Law and the Regulation for Application of the Coastal Law, Shore Border Line (SBL) infringing sections of a real estate that remain on the coast should be annulled from the title and they should be allocated for public use. In practice, owing to the fact that institutions, which perform title annulment procedures, collect the required spatial data from the related institutions via traditional methods, it is seen that procedures are carried out quite slowly, and the process of title annulment lasts for months. Effective cooperation among many different institutions is needed in the management of coastal areas. The mechanism that will ensure this cooperation is “Spatial Data Infrastructure (SDI).” The SDIs are inter- operability infrastructures that allow sharing of the data and services among the related institutions or parties. Service Oriented Architecture and its most common implementation method, web services, are the latest software architecture that is recommended for realizing interoperability. In this study, the legislation related to management of coastal areas in Turkey is examined and institutions, which appear in the process of title annulment of real estates, which remain on the coast by infringing the SBL, and the procedures carried out are explained. Next, a series of web services were designed and developed for an SDI implementation, and it is demonstrated that procedures which are in practice implemented quite slowly by traditional methods can be implemented in a fast and proper manner in a web services-based SDI environment

    Bu araştırmada sınıf öğretmenlerinin erken cebire yönelik düşüncelerinin belirlenmesi amaçlanmıştır. Araştırmada, bir gruba ait belirli özelliklerin saptanması amaçlandığından tarama modeli benimsenmiştir. Araştırma verileri, araştırmacılar tarafından geliştirilen “Erken Cebir Farkındalık Ölçeği” aracılığıyla toplanmıştır. Araştırmada ölçeğin geliştirilme aşaması (217 sınıf öğretmeni) ve geliştirilen ölçeğin uygulanma aşaması (240 sınıf öğretmeni) olmak üzere iki farklı çalışma grubu bulunmaktadır. Ölçeğin uygulanması sonucu elde edilen sayısal verilerin analizinde SPSS programından faydalanılmıştır. Bu kapsamda iki grubun ortalamalarının karşılaştırılmasında nonparametrik testlerden Mann-Whitney U testi ve ikiden fazla grubun ortalamalarının karşılaştırılmasında Kruskal-Wallis H testi uygulanmıştır.  Nitel verilerin analizinde ise içerik analizi tekniği kullanılmıştır.  Araştırma sonucunda sınıf öğretmenlerinin erken cebire yönelik bilgilerinin sınırlı olduğu sonucuna ulaşılmıştır. Dolayısıyla sınıf öğretmenlerine yönelik erken cebir kapsamında yapılacak eğitim programlarının öğretmenlerde erken cebir düşüncesinin gelişimine katkı sağlayacağı söylenebilir

Volume and surface rendering techniques have been used to construct 3D models of tissues. In this study, an application has been made to find the location of tumor cited on human brain. During the application some control points have been located on to the face of the patient and then her/his head has been scanned with CT and MR scanners. Digital images of the patient?s head, have also been taken. By using CT and MR images, 3D models of both brain tissues and outer face surface have been constructed. These models have been transformed to object coordinate system by using control points. On the other hand, by using digital photographs of patient?s head, photo-realistic visualization of the 3D face model has been obtained by texture mapping. Finally, tumor has been detected and its location has been obtained. In order to realize above works, medical imaging and photogrammetry software has been developed. This software has been coded with Borland C++ Builder. Furthermore, open source VTK C++ libraries, which supports OpenGL have been used and when required, VTK?s functions have been modified.

    There is no effective treatment for the Covid-19 disease that is still impacting the whole world. It considered that vaccines, one of the effective means to prevent infectious diseases, will play a significant role in protecting from the Covid-19 Disease. Vaccinations generals performed before exposure. We aimed to follow the clinical and laboratory progress of patients who got Covid-19 after the first dose of the Covid-19 vaccine and to evaluate the changes that may occur in antibody formation. 13 patients, who received the first dose of COVID 19 vaccine Coronovac as of 14.01.2021 when vaccination started in Adıyaman University Training and Research Hospital/Turkey, who had symptoms after the vaccine and whose real-time PCR found to be positive, were included in the study. After the first dose of the Covid-19 vaccine, 13 patients exam. Three of our patients were female, and 10 of them were male. The average age was 38.8. British variant detected in 4 of our patients; 1 of them was female. Contact times differed between 3 and 5 days. The most common symptoms were muscle-joint pain (53.8), weakness-fatigue (46.2), fever (38.5), and headache (30.8). Three of our patients, being one female, received inpatient treatment. Furthermore, our five patients who checked regarding Sars cov-2 IgG became positive in the first month. No adverse changes in the course of the illness observed in the patients were RT-PCR positive after the first dose of the Covid-19 vaccine. Antibody response detected at the end of the first month.  Vaccination is an effective method for taking infectious diseases under control but adhering to personal protective measures still maintains their importance
