The perceptions of supervising teachers on the prospective-teacher training: A phenomenographic research

The main purpose of this research is to identify the perceptions of supervising teachers on prospective- teacher training through phenomenographic method. Phenomenography is a method which determines how the people perceive the events and issues around them and how they explain them by conceptualizing. The working group of the research includes Subject and Classroom teachers working in the central provinces of Siirt and Batman chosen by random sampling. As data collection tool, questions that teachers' personal information take place and a semi-structured interview form including three open-ended questions trying to state the perceptions about  prospective- teacher training are prepared and in order to determine the validity of the questionnaire it was submitted to two experts. In accordance with the expert opinions, the interview form has been made ready to apply with necessary corrections. The first question in the interview form is “To me, the prospective- teacher training means…… ” the second one is “The positive sides of prospective- teacher training are……………………. Because……..”, and the third one is “The negative sides of the prospective-teacher training are ……….....Because……”.  A period of 20-25 minutes is given to specify the perceptions of teachers on the prospective- teacher training. Teachers’ answers to these questions / opinions have been adopted as the main source of research data. These concepts and statements have been transferred to the computer and as a result of eliminations made in the computer, the remaining concepts and statements are divided into certain categories. Proposals have been made in accordance with the categories obtained

Araștırma sonunda, Birgi bütünleșik koruma alanları örneğinde tarihsel kentlerin sürdürülebilir korunması–geliștirilmesine yönelik yönetișim, mekânsal, sosyal–ekonomik, kültürel ve finansal içerikli programlardan olușan kültürel miras yönetim modeli tanımlanmıștır. Bu modelin, Türkiye tarihsel kentleri üzerine odaklanan koruma–yenileme çalıșmalarının, sürdürülebilirlik ilkesi temelinde kapsam ve içeriği ile kurumsal altyapısının tanımlanmasına yönelik yöntem izlencesi ve örgütlenme modeli arayıșlarına, özellikle alan yönetimi tartıșmaları düzeyinde katkı sağlayacağı düșünülmektedir

Two Electrons in a Quantum Dot: A Unified Approach

Low-lying energy levels of two interacting electrons confined in a two-dimensional parabolic quantum dot in the presence of an external magnetic field have been revised within the frame of a novel model. The present formalism, which gives closed algebraic solutions for the specific values of magnetic field and spatial confinement length, enables us to see explicitly individual effects of the electron correlation.Comment: 14 page

Netipični nalazi magnetske rezonancije u cerebralnoj adrenoleukodistrofiji: prikaz slučaja

Adrenoleukodystrophy is a rare X-linked hereditary disease that results in accumulation of very-long-chain fatty acids in all body tissues, thus causing demyelination of the white matter. Magnetic resonance imaging (MRI) is a reliable radiological modality to demonstrate the extension of brain lesions and severity of the disease. In the classic form, the parieto-occipital white matter is affected. Besides, atypical MRI findings such as primary frontal lobe involvement are rarely described. We report a case of adrenoleukodystrophy presenting with rare MRI findings such as bilateral symmetric frontal lobe white matter changes suggesting anterior predominance.Adrenoleukodistrofija je rijetka X-vezana nasljedna bolest nakupljanja masnih kiselina dugog lanca u svim tjelesnim tkivima, što uzrokuje demijelinizaciju bijele tvari. Magnetska rezonancija (MR) je pouzdana radiološka metoda kojom se dokazuju razmjeri oštećenja mozga i težina bolesti. U klasičnom obliku bolesti zahvaćena je parieto-okcipitalna bijela tvar. Uz to, rijetko se opisuju netipični nalazi MR kao što je primarna zahvaćenost frontalnog režnja. Opisujemo slučaj adrenoleukodistrofije koja se prikazala rijetkim nalazima MR, tj. obostranim simetričnim promjenama bijele tvari u frontalnom režnju, ukazujući na prevladavajuću zahvaćenost prednjih dijelova

The use of finite element method in the furniture industry

The reason of this can be determined as the possibility of application of the CAE system besides the development of administration comprehension and industry with personal computers. In this study, Finite Element Method (FEM) application, which is an important engineering technique, was investigated with SolidWorks/CosmosWorks system. It is aimed to discuss the difficulties of FEM application based on the structure of the wood material and the conditions to transfer these to the Furniture Industry. For this purpose, proper analysis coefficient and virtual resistance values were developed with available standard, theoretic information and industrial application examples. At the second stage, the analysis was applied on a real product and the accuracy and applicability of the analysis approach have been evaluated by comparing the theoretic behavior of the product based on the software with the real results in practice

Black carbon traces of human activities in stalagmites from Turkey

Speleothems are recognized as sensitive recorders of climatic fluctuations in the past and provide precisely dated and highly resolved environmental records. However, their potential as an archaeological archive is not fully acknowledged yet. Here we present several stalagmites containing soot and charcoal layers from various caves in Turkey and provide evidence that these black carbon layers are directly related to human activity. The archaeological artefacts found in Tabak and Kocain caves in SW Turkey support the linkage between soot and charcoal layers existence and human activity in the caves. For this study, we focus on stalagmites from Tabak and Kocain cave. To explore the age and nature of the soot and charcoal layers within stalagmites Ta-9, Ta-10 and Ko-1, Uranium series dating, scanning electron microscope (SEM) and thin section analyses were performed. The episodic soot and charcoal deposition in stalagmites Ta-9 and Ta-10 occurred between 7424 +/- 225 yr BP and 6670 +/- 218 yr BP while the soot and charcoal layers in stalagmite Ko-1 formed between 2830 +/- 189 yr BP and 470 +/- 56 yr BP. In combination with the archaeological inventory in Tabak Cave, the soot and charcoal layers within stalagmites Ta-9 and Ta-10 show that the cave was used repeatedly as a burial site during Chalcolithic period. In Kocain Cave was also used repeatedly between the Iron Age and Medieval Period, most likely for ritual activities and for providing animals with water from a small spring in the entrance to the cave. The soot and charcoal layers within stalagmites from Turkey prove that speleothems are also important as archaeological archives
