Perceptions of Pre-Service Teachers on Ethical Teacher and Professional Ethics Course

The purpose of the present study is to figure out the perceptions of pre-service teachers on the characteristics of ethical teacher and feasibility of Professional Ethics course that offered in a teacher certificate program. The study adopted an exploratory qualitative research design to explore the perceptions of the participants in depth. The participants of the study were 15 volunteer pre-service teachers who were selected with the convenience sampling technique. The data were gathered through semi structured one-to-one interviews and descriptively analyzed by means of content analysis technique. The analysis of the data revealed that participants perceived the teachers as ethical when they maintain professional relationships and do not discriminate students, demonstrate respect for diversity, maintain fairness and promote equality, act with honesty, integrity and fairness, take responsibility for maintaining the quality of their professional practice, maintain an up to date knowledge, work in a collegiate and cooperative manner with colleagues and other professionals and act obedient to law and regulations. Additionally, findings revealed that professional ethic course enable participants to gain awareness on ethical codes of teaching profession, able to identify ethical and unethical behaviors as well as increase their willingness to act in line with the codes of teaching professional ethics

The effect of thiosemicarbazone derivatives on some blood parameters in rats

Çalışmada, deney grubu ratlara 45 günlük deney süresince üçer gün ara ile deri altı yolla 25 mg/kg tiyosemikarbazon ve 25 mg/kg tiyosemikarbazon-çinko kompleksi uygulandı. Uygulamaların serum aspartat amino transferaz (AST), alanin amino transferaz (ALT), laktat dehidrogenaz (LDH), gamma-glutamil transferaz (GGT) aktivitelerine ve üre, kreatinin, total ve direkt bilirubin düzeylerine, karaciğer ağırlığına ve canlı ağırlığına etkileri belirlemek için 60 adet rat kullanıldı. Ratlar kontrol grubu, tiyosemikarbazon uygulanan grup ve tiyosemikarbazon-çinko kompleksi uygulanan deney grubu olmak üzere üç gruba ayrıldı. Uygulamanın 7., 15., 30. ve 45. günlerinde her gruptan 5’er rat ayrılıp tartılarak dekapite edildi; kanları alınıp karaciğer ağırlıkları kaydedildi. Gerekli analizler otoanalizörde spektrofotometrik yöntemle yapıldı. Tiyosemikarbazon ve tiyosemikarbazon-çinko kompleksi uygulanan ratların serum AST, ALT, LDH ve GGT aktiviteleri ile üre, kreatinin, total ve direkt billirubin düzeyleri, karaciğer ağırlıkları ve canlı vücut ağırlıklarının kontrol grubuna göre istatistiksel olarak önemli bir fark göstermediği (p>0.05) bulundu. Ratlara deri altı yolla verilen 25 mg/kg tiyosemikarbazon ve tiyosemikarbazon-çinko kompleksinin çalışılan serum parametrelerini, karaciğer ağırlığını ve canlı ağırlığı etkilemediği gözlendi. Buna bağlı olarak ta tiyosemikarbazon veya tiyosemikarbazon-çinko kompleksinin tedavi amaçlı kullanıldığında uygun doz ayarlaması ile yan etkilerinden korunulabileceği düşünüldü.In this study, 25 mg/kg thiosemicarbazone and 25 mg/kg thiosemicarbazone-zinc complex were given to the experiment group rats subcutoneusly at an interval of three days. 60 rats were used to determine of the effect of thiosemicarbazone and thiosemicarbazonezinc complex on the rats, the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), gamma-glutamyl transferase (GGT) and levels of urea, creatinine, direct billirubin, total billirubin in serum and liver weight and live weight of rats. Rats were divided into three groups namely the control group and the two experimental groups exposed to thiosemicarbazone and thiosemicarbazone-zinc complex. Five rats from the each group at 7th, 15th, 30th, 45th days of application were separated and weighed and then decapitated. Their bloods were taken and their liver weights were recorded. Necessary analyses were conducted through the autoanalyser and no statistically significant differences were found in activities of AST, ALT, LDH, GGT, and levels of urea, creatinine, total and direct billirubin in serum of rats exposed to thiosemicarbazone and thiosemicarbazone-zinc complex, and their liver weight and alive weights relative to control group (p>0.05). It has been observed that 25 mg/kg thiosemicarbazone and 25 mg/kg thiosemicarbazone-zinc complex given subcutoneusly to the rats did not affect some of their blood parameters, and liver and live weights of rats. As a result, it was thought that when thiosemicarbazone and thiosemicarbazone-zinc complex were used for the purpose of treatment, from their side effects might be avoided by adjusting suitable doses of those substances

Hybrid Ventilation System Simulation for Several Cities in Turkey

Hybrid ventilation systems combine the superior properties of natural and mechanical ventilation systems to reduce energy consumption. In this study, hybrid ventilation simulations were performed for several cities in Turkey, which have different climate conditions. Matlab/Simulink was utilized to perform the simulations. The results of these simulations were compared with that of regular air conditioning units in terms of energy consumption. A hybrid ventilation system which shows the general behaviour of a fan-assisted natural ventilation system with temperature-based control and which provides both heating and cooling, is shown to be effective for four cities in Turkey that have different climate conditions. Results showed potential savings of around 25-30% when compared to a regular AC system
