The Postgraduate Education of Teachers and its Effects on Their Instructional Activities

This study investigates the contributions of the postgraduate education to in-service training of teachers and its reflections into classroom setting. For this purpose, volunteer teachers and courses mostly chosen by them were selected and skills these courses aim to provide were determined. The sampled teachers were also observed and interviewed. The study highlighted coherence between the qualities that teachers supposed to have and the skills aimed to be gained via this education and therefore, confirmed that postgraduate education contributes to in-service training of teachers. Finally, although teachers do their best to put these skills into practice, some skills can not be applied properly due certain difficulties explained in this article

Sensibilidade moral, experiências éticas e fatores relacionados da enfermagem pediátrica: um estudo transversal correlacional

The aim of this study is to determine the ethical experiences and the level of moral sensitivity and related factors of pediatric nurses working in hospital settings. Designed as descriptive and cross-sectional, the study was undertaken at three public hospitals in Konya and Ankara, Turkey and included the participation of a total of 200 pediatric nurses. The Moral Sensitivity Questionnaire (MSQ) was used for evaluation of the ethical sensitivities of the nurses. Of the 200 nurses, 46.5% had working experience of between 1–5 years, 58% were married, 18.6% had not undergone any ethics education, and 59.5% held a bachelor’s degree. A large majority (95%) of the pediatric nurses reported that they had encountered ethical problems. The mean moral sensitivity score of the nurses was 95.89±24.34, with higher scores in this area being observed in the nurses who were in the older age group and had worked longer than others (pEl objetivo de este estudio consiste en determinar las experiencias éticas y el nivel de sensibilidad moral y factores relacionados de enfermeras pediatras que trabajan en hospitales.

Removal of naproxen and diclofenac using magnetic nanoparticles/nanocomposites

Magnetic iron oxide and iron/copper nanoparticles were synthesized using Lathyrus brachypterus extract, and then magnetic Fe3O4–CS, Fe3O4–AT, Fe/Cu–CS and Fe/Cu–AT nanocomposite beads were synthesized using chitosan and alginate natural polymers. They were used for both adsorption and heterogeneous catalysts for the catalytic wet peroxidation (CWPO) of naproxen (NPX), diclofenac (DCF) and NPX + DCF drugs which are important micro-organic pollutants, separately and together (NPX + DCF) from aqueous media. In adsorption studies, the drugs were adsorbed very quickly in the first minutes and then, desorbed in between 8 and 10 min. In competitive adsorption, the adsorbents showed selective properties for DCF and NPX. In CWPO technique, drug removal was achieved in 9 min with a conversion capacity of 92% for DCF with Fe/Cu–CS and 84% for NPX with Fe/Cu–AT optimum experimental conditions, such as pH 5, 30% of H2O2, 100 mg catalyst and 298 K. Based on reusability of the catalysts, it was seen that there was a slight decrease in the removal efficiencies in the third cycle and the stable and active structure of the catalyst was preserved to the desired extent. Furthermore, the oxidation reaction was in good agreement with the pseudo-first-order kinetic model.

Adsorption, oxidation, kinetic and thermodynamic studies of methyl orange by magnetic Fe3O4 NPs and their chitosan/alginate nanocomposites

Magnetic iron oxide (Fe3O4) nanoparticles, iron oxide chitosan (Fe3O4-CS) and iron oxide alginate (Fe3O4-AT) nanocomposite beads were synthesised using green synthesis method. They were used as both adsorbents for the adsorption of methyl orange (MO) dye from the wastewater and heterogeneous catalysts for the catalytic wet peroxidation (CWPO) of MO. While the dye removal was successfully performed with Fe(3)O(4)NPs, Fe3O4-CS and Fe3O4-AT in both adsorption studies and CWPO, the highest removal efficiency (99%) in the shortest time (8 min for adsorption, 20 min for CPWO) was obtained with Fe3O4-CS for MO removal. The adsorption experiments were performed with the batch techniques at different contact time, pH, initial dye concentration, temperature, amount of adsorbent and foreign ion effect parameters by Fe3O4-CS adsorbent. The equilibrium was quickly reached after 30 min at pH 3 and 298 K. Fitting equilibrium data to Langmuir, Temkin and Freundlich isotherms showed that Langmuir model was more suitable to describe MO adsorption with a maximum monolayer adsorption capacity of 132 mg/g at 298 K. The Experimental data were analysed using intra particle diffusion, pseudo-first-order and pseudo-second-order kinetic models and it was found that the adsorption kinetics followed a pseudo-second-order equation. Based on thermodynamic studies, adsorption process occurred as spontaneous and exothermic. The effects of the amount of catalyst, pH, temperature and H2O2 concentration were investigated to determine their catalytic activities for the decomposition of MO with CWPO technique. The reusability of Fe3O4-CS for both adsorption and CWPO techniques for MO removal was performed, and the adsorption and oxidation efficiency was found to be 97%. Moreover, the reaction kinetics was also investigated and the oxidation reaction was in good agreement with the pseudo-first order kinetic model. The activation energy (Ea) of the reaction was found to be 10.72 kJ/mol

Effects of Regenerated Sportive Activities on the Empathic Tendency of Women

The purpose of this study is to determine the levels of empathy for regularly exercising women and to determine whether empathy levels differ according to some variables.The study is planned as a single group pretest-posttest. 178 sedentary and healthy adult women participated in the study as a volunteer. Aerobic-Dance Exercise program was applied to the participants 60 minutes a day, 3 days per week for 8 weeks; then, The Empathic Tendency Scale (EQS) were filled at the beginning and at the end of the exercise program. The validity and reliability study of the scale was conducted by Dokmen (1988).Statistical Package for Social Sciences (SPSS) 16.00 software was used in the analysis of the data obtained from the research. One way ANOVA was used to determine the differences between the groups when the data showed normal distribution and after the homogeneity of the variances was tested, the Tukey test was used for differences between the groups and the error level was taken as 0.05.When the findings are examined; the mean score of " Empathic Tendency " according to the marital status, the study status and the number of children of the participants was statistically significant in the pretest-posttest after the exercise program (p0.05). As a result, it was seen that exercise had a positive effect on the "Empathic Tendency” levels of the women participating in the study

Examination of Some Physical Fitness and Motor Skill Parameters of Pre-Adolescents and Adolescents

The aim of this study was to analyze the importance of some physical fitness and motor skills for children between 11-13 years at elementary school. A total of 114 primary school children participated as volunteers with a means age of 10.80 ± 0,40 for 5th grade and 12.83 ± 0,38 for 7th grade.In this study, some motor tests were used to detect differences between pre-adolescence and adolescence on male and female. These tests were respectively: for dynamic balance “The Star excursion balance test”, for the agility “T-test”, “V sit and reach” for flexibility test and for explosive strength a “20 m run (0.1s)”. Besides, physical fitness features were taken as height, weight, body mass index (BMI) and waist-hip ratio (WHR).The results of the flexibility showed that the female children had better performances in the 5th grade than those in the 7th grade children (p<0,005). In addition, it was determined that the dynamic balance performance values of the 7th grade female and male children were better than the 5th grade(p<0,005). There were significant differences in agility and explosive strength between the 7th grade female and male children(p<0,005). It was observed that there was an increase in agility, speed and dynamic equilibrium performance data especially from the age of 11 in parallel with growth and development. Especially from this period, it was thought that it was possible to develop motor skills and performance parameters with some sports applications and training

Aorta abdominalis’in ana dallarının multidedektörlü bilgisayarlı tomografik anjiografi (mdbta) ile incelemesi

06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Giriş ve Amaç: Renal ve mezenterik arteriyel varyasyonlar toplumda oldukça sık olarak görülmektedir ve bu varyasyonların bilinmesi cerrahi işlemlerde ve görüntülemede oldukça önemlidir. Bu nedenle çalışmamızda, aorta abdominalis (AA)'in ana dallarını incelemeyi ve bazı ölçümler yaparak cinsiyet farkını da göz önüne alıp değerlendirmeyi amaçladık. Gereç ve Yöntem: Çalışmamız, 18-97 yaş aralığında; 200 (61 kadın, 139 erkek) Multidedektörlü bilgisayarlı tomografi (MDBT) anjiyografi görüntüsünde retrospektif olarak yapılmıştır. Aorta abdominalis ve dallarından, Truncus coeliacus (TC), arteria mesenterica superior (AMS), arteria renalis dextra (ARD), arteria renalis sinistra (ARS), arteria mesenterica inferior (AMI) incelendi. Bu arterlerde yapısal varyasyon gözlenen olguların MDBT görüntüleri ayrı kaydedildi. Çalışma verileri istatistiksel (SPSS 21 programında) olarak analiz edildi. Bulgular: 200 vakanın %91'inde normal TC anatomisi, % 9'unda ise TC varyasyonları izlenmiştir. AR (arteria renalis) de; sağ taraf çift sol tarafta tek renal arter varlığı %10.5 ile en sık varyasyon olarak görülmüştür. AMS'dan çıkan replase sağ hepatik arter varlığı sadece bir hastada tespit edilmiştir. AMI'da varyasyon izlenmemiştir. İncelenen arterlerin vertebra çıkış seviyelerinin genelinde cinsiyetler arasında anlamlı bir farklılık gözlemlenmemiştir. AA'in dallarını verdiği seviyelerdeki çap ölçümlerinde ve bu dalların çıkış yerlerinin birbirlerine olan mesafelerinde, cinsiyetler arasında istatistiksel olarak anlamlı farklılıklar tespit edilmiştir. Tüm bu sonuçlar, literatürlerdeki çalışma sonuçları ile karşılaştırılarak tartışılmıştır. Sonuç: Mezenterik ve renal arteriyel varyasyonların farkında olunması, kolon, rectum, hepatobiliyer, pankreatik hastalıklarda ve renal tranplantasyonlarda hayati önem taşır ve bu arterlerin vertebra seviyeleri, çap ve mesafe ölçümleri radyolog ve cerrahlara büyük kolaylıklar sağlar. Çalışmamızın daha önceki literatürlerin yenilenmesine, desteklenmesine ve anatomiye katkıda bulunacağını düşünüyoruz. Anahtar Kelimeler: MDBT, Aorta Abdominalis, Varyasyon, Retrospektif, RadyolojikExamination Of The Main Branches Of Aorta Abdominalis With Multidetector Computed Tomography Angıography Introduction and aim: Renal and mesenteric arterial variations are encountered quite frequently in the community, and the remembering those variations is very crucial in surgical procedures and imaging. Therefore, we aimed both to examine the main branches of aorta abdominalis (AA) and to evaluate the gender difference through some measurements. Materials and Methods: In our retrospective study, multidetector computed tomography (MDCT) angiography images of 200 subjects (61 female, 139 male) aged 18-97 years was used. Abdominal aorta and its branches including celiac trunk (TC), superior mesenteric artery (AMS), right renal artery (ARD), left renal artery (ARS), inferior mesenteric artery (AMI) were examined. MDCT images of cases with structural variation in these arteries were recorded separately. The study data were analyzed statistically using SPSS 21 Program. Results: Normal TC anatomy was observed in 91% of the 200 cases and TC variations were observed in 9% of the cases. The situation in terms of renal artery is: the presence of RA is double at right side but single at left side. And this type of variation is seen by us as the most common variation (10.5%). The presence of a displaced right hepatic artery originating from AMS was detected in only one patient. No variation in AMI was observed. When the arteries were examined according to the vertebral levels, no significant difference was observed between the genders in general. A statistically significant difference was detected between the genders in terms of the diameters of AA at the levels where AA gave its branches and the distance of the origins of those branches of AA to each other. All of these results were compared with the results of the literature. Conclusion: Being aware of the variations of mesenteric and renal arteries is of vital importance in colon, rectum, hepatobiliary, pancreatic diseases and renal transplantations. And the vertebral levels of those arteries, measurements of their diameter and distance provide with great convenience in radiologists and surgeons. We believe that our study will contribute to the renewal and support to previous studies of literature and anatomy. Key words: MDCT, abdominal aorta, variation, retrospective, radiologica
