Okul öncesi öğretmenlerinin okul dışı öğrenme faaliyetlerine yönelik görüşlerinin incelenmesi

Phenomenology, one of the qualitative research designs, was used in this study, which aims to examine how preschool teachers perceive out-of-school learning activities. Participants in the study were determined using an easily accessible sampling method. In this context, research was carried out with 19 pre-school teachers in a city that the researcher can easily reach. Research data were collected using a semi-structured interview form. The data were analyzed using the content analysis technique, using Excel and Word programs. As a result, within the framework of the opinions of preschool teachers participating in the study; OSLA's (out-of-school learning activities) predominantly include learning (permanent learning, indoor and outdoor learning, learning reinforcement, and experience), child contribution (skill development and obtaining educational program outcomes) and environment (institutions/ organizations, garden-greenhouse, theater / cinema and nature). According to the teachers, the main problems in terms of the execution of OSLA and the problems encountered in the process; security and control of children, parents' anxiety and unwillingness, the cost of the activity, the incompatibility of the curriculum, bureaucratic procedures and communication difficulties with children. Teachers' opinions about the competence of OSLA; shows that they did not receive in-service training or insufficient in-service training. In addition, it is understood that teachers have a positive perception of competence in terms of good research, preparation, and planning, benefiting from relevant guides and coping with difficult conditions. On the other hand, it is seen that they have a negative perception of efficacy in ensuring child safety and having difficulty coping with children.Okul öncesi öğretmenlerinin okul dışı öğrenme faaliyetlerini nasıl algıladıklarını incelemeyi amaçlayan bu araştırmada nitel araştırma desenlerinde biri olan olgubilim (fenomenoloji) kullanılmıştır. Araştırmada katılımcılar kolay ulaşılabilir örnekleme yöntemiyle belirlenmiştir. Bu kapsamda bir ilde araştırmacının kolay bir şekilde ulaşabildiği 19 okul öncesi öğretmeni ile araştırma gerçekleştirilmiştir. Araştırma verileri yarı yapılandırılmış görüşme formu ile toplanmıştır. Veriler içerik analizi tekniğiyle, Excel ve Word programlarından yararlanılarak analiz edilmiştir. Sonuç olarak, araştırmaya katılan okul öncesi öğretmenlerinin görüşleri çerçevesinde; ODÖF’ün (okul dışı öğrenme faaliyetleri) öğretmenler için ağırlıklı olarak öğrenme (kalıcı öğrenme, kapalı ve açık alanlarda gerçekleştirilen öğrenme, öğrenmeyi pekiştirme ve deneyim), çocuğa katkı sağlama (beceri geliştirme ve öğretim program kazanımlarını elde etme) ve ortam (kurum/kuruluşlar, bahçe-sera, tiyatro/sinema ve doğa) anlamlarına geldiği görülmektedir. ODÖF’ün yürütülmesi ve süreçte karşılaşılan sorunlar anlamında öğretmenlere göre başlıca sorunların; çocukların güvenlik ve kontrolü, veli kaygısı ve isteksizliği, faaliyetin maliyeti, öğretim programının tam olarak uygun olmaması, bürokratik prosedürler ve çocuklarla yaşanan iletişim güçlüğü olduğu anlaşılmaktadır. Öğretmenlerin ODÖF açısından yeterlilikleri hakkındaki görüşleri; konuyla ilgili hizmetiçi eğitim almadıklarını ya da yetersiz hizmet içi eğitim aldıklarını ortaya koymaktadır. Ayrıca öğretmenlerin, ODÖF ile ilgili iyi araştırma, ön hazırlık ve plan yapabilmeleri, ilgili kılavuzlardan yararlanabilme ve zor koşullarla baş edebilmeleri konusunda olumlu yeterlik algısına sahip oldukları anlaşılmaktadır. Diğer taraftan, çocuk güvenliğini sağlama ve çocuklarla baş etmekte zorlanma konusunda olumsuz yeterlik algısına sahip oldukları görülmektedir

DESIGNING A FORECAST MODEL FOR ECONOMIC GROWTH OF JAPAN USING COMPETITIVE (HYBRID ANN VS MULTIPLE REGRESSION) MODELS

Artificial neural network models have been already used on many different fields successfully. However, many researches show that ANN models provide better optimum results than other competitive models in most of the researches. But does it provide optimum solutions in case ANN is proposed as hybrid model? The answer of this question is given in this research by using these models on modelling a forecast for GDP growth of Japan. Multiple regression models utilized as competitive models versus hybrid ANN (ANN + multiple regression models). Results have shown that hybrid model gives better responds than multiple regression models. However, variables, which were significantly affecting GDP growth, were determined and some of the variables, which were assumed to be affecting GDP growth of Japan, were eliminated statistically

Curative Chemoradiotherapy of Primary Pancreatic Lymphoma with Vertebral Metastasis: Palliation of Persistent Biliary Stricture by Roux-en-Y Hepaticojejunostomy

Primary pancreatic lymphoma (PPL) is a rare tumor that usually presents with the clinical picture of advanced adenocarcinoma but has a much better prognosis. A 38-year-old man was referred after percutaneous transhepatic external biliary drainage for obstructive jaundice. Abdominal magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography had revealed a 5-cm pancreatic head mass that caused biliary tract dilation. Computed tomography angiography showed that the mass encased the celiac trunk as well as the common hepatic and splenic arteries. MRI also revealed a metastatic lesion at the third lumbar vertebra. Serum carcinoembryonic antigen and carbohydrate antigen 19-9 levels were within normal range. The initial diagnosis was inoperable pancreatic adenocarcinoma; however, Tru-Cut pancreatic biopsy showed a large B cell lymphoma. After 6 sessions of chemotherapy and 21 sessions of radiotherapy, both the pancreatic mass and the vertebral metastasis had disappeared. However, he had persistent distal common bile duct stricture that could not be negotiated by either the endoscopic or percutaneous route. A Roux-en-Y hepaticojejunostomy was performed. The patient stayed alive without recurrence for 52 months after the initial diagnosis and 45 months after completion of oncologic treatment. In conclusion, a large pancreatic mass with grossly involved peripancreatic lymph nodes, without ascites, liver or splenic metastasis, should alert the clinician to the possibility of PPL. Cure is possible by chemoradiotherapy even in the presence of vertebral metastasis. Persistent stricture in the distal common bile duct may require a biliodigestive anastomosis

Detemination of molecular phylogenetic properties of orchic laxiflora and of orchis punctulata (orchidaceae) taxa using the technique of DNA sequenccing

Yüksek Lisans TeziBu tez çalışmasında Orchidaceaea familyasına ait Orchis laxiflora ve Orchis punctulata taksonlarının, sistematik ve moleküler filogenetik özellikleri sahip oldukları genomik DNA’larının 18S ve ITS1 bölgeleri sekanslanarak ortaya konulmuştur. Slika – jel yöntemiyle kurutulmuş bitki örneklerinin basal yaprak hücrelerinden genomik DNA’ları izole edilmiş ve 18S rDNA ve ITS1 bölgeleri önceden hazırlanmış primerler kullanılarak çoğaltılmıştır. Bu çoğaltılmış bölgelerin DNA sekanslaması yapılarak elde edilen veriler, bazı biyoinformatik ve filogeni programları ile çalışılarak bu bitkilerin moleküler düzeyde sınıflandırılmaları ilk kez ortaya koyulmuştur. CLUSTALW2 yazılımı kullanılarak üzerinde çalışılan bitkilerin diğer Orchidaceae üyeleri ile olan hizalamaları tespit edilirken MEGA 4,0 (STABLE) yazılımının Neighbour – Joining (Saitou ve Nei, 1987) metoduyla da filogenetik ağaçları oluşturulmuştur. Hizalama sonucu oluşan matrix – join tablosu ve filogenetik ağaç oluşturma işlemi sonucu elde edilen veriler klasik taksonomi verileri ile karşılaştırılmıştır. Bu tez çalışması ile O. laxiflora ve O. palustris’in A. coriophora, A. morio, A. champagneuxii ve A. pyramidalis ile ayrı bir grup oluşturduğu, O. punctulata’nın ise O. italica, O. mascula, O. militaris, ve O. purpurea ile ayrı bir grup oluşturduğu, ayrıca O. punctulata’nın Orchis cinsi içinde kalmaya devam etmesinin, O. laxiflora ve O. palustris’in ise Anacamptis cinsine aktarılmasının doğru olacağı sonuçlarına varılmıştır.AbstractIn this study systematic and phylogenetic properties of the taxons of Orchis laxiflora and Orchis punctulata from the Orchidaceae family were determined by sequencing 18S rDNA and ITS2 regions of their genomic DNA. Genomic DNA’s were isolated from basal leaf cells of plant samples which were dessicated by silica-gel method. The 18S rDNA an ITS1 regions were amplified by previously prepared primers. The classification of these orchid species at the molecular level was accomplished for the first time, by applying bioinfomation and phylogenesis programs on the data obtained from the DNA sequences of these amplified regions. CLUSTALW2 program was used to determine the leveling of the species in question, with the other Orchidaceae species. Their phylogenetic trees were built by using the Neighbour-Joining (Saitou and Nei, 1987) method of MEGA 4,0 (STABLE) program. The data obtained from the matrix-join table and phylogenetic trees were compared with the classical taxonomical data. In conclusion, O. laxiflora and O. palustris were grouped together with A. coriophora, A. morio, A. champagneuxii and A. pyramidalis, in the same group, whereas O. punctulata was grouped with O. italica, O. mascula, O. militaris, and O. purpurea. Therefore it was proposed to keep O. punctulata to belong to the genera Orchis, but O. laxiflora and O. palustris to be transferred to the genus Anacampti

Prospective Pre-School Teachers’ Attitudes towards Astronomy

The purpose of this study is to examine the changes in prospective pre-school teachers’ attitudes towards astronomy in terms of their grades. The study was conducted with 205 prospective teachers (1st, 2nd, 3rd, 4th graders) studying in the education faculty of a university in Eastern Anatolia region of Turkey. Astronomy Attitude Scale (AAS) was used as data collection instrument. One-Way Anova was used for independent groups in data analysis in order to find out whether prospective pre-school teachers’ attitudes towards astronomy differed in terms of their grades. Data analysis results showed that prospective pre-school teachers’ attitudes towards astronomy did not differ significantly in terms of their grades. In addition, it was concluded that while prospective pre-school teachers had positive attitudes such as associating astronomy with daily life, thinking that astronomy can be learned better through applied activities and contemporary developments about astronomy attracted their attention, they also had negative attitudes such as feeling insecure about astronomy subjects and not liking the field of astronomy. In line with these results, it was recommended that the number of physical sciences lessons in pre-school teaching departments in education faculties should be increased

Ateşli Silah Yaralanmasina Bağli Geç Dönem Gelişen Subklavian Arter-Ven Fistülü

Traumatic arterio-venous fistula usually results from gunshot wounds. A-V fistula may be diagnosed several years after trauma. Most of the A-V fistulas are seen at lower extremities but Subclavian A-V fistula is less common in general. A 81 year old woman was admitted to hospital with swelling at right anterior portion of neck which happened 30 years ago because of gunshot wound.. Computed tomography and magnetic resonance (MR) angiography showed arteriovenous fistula between distal part of right subclavian artery and subclavian vein. Endovascular surgery was planned, but patient and her relatives did not accept operation. We want to report an arteriovenous fistula which was happened 30 years before due to gunshot woun
