Perceptions of In-Service Teachers Regarding Technology Integrated English Language Teaching
AslLidice Gktürk Salam,Semih Sert
Turkish Online Journal of Qualitative Inquiry , 2012,
Abstract: Technology is changing paradigms in education rapidly and teachers are caught unguarded due to lack of professional training in this aspect. This study reflects the perceptions of nine ELT instructors with M.A TEFL degrees and with over six years of professional experience. Despite the lack of formal professional training as part of their pre-service teacher education, these instructors need to cope with the demands of this transition in daily implementation. Data were collected through semi-structured interviews, open-ended questionnaires and field notes. An inductive analysis approach was used to analyze the data and emergent patterns of data were used to develop coding categories. Results indicated that respondents held positive views about the role of educational technology for enriching language instruction. However, they also acknowledged the challenges faced and emphasised the need for ICT training not only for teachers but also for students. It is concluded that participants make use of technology to teach academic and linguistic skills in an integrated skills approach, encourage students to construct knowledge, expose students to life-long learning skills and strategies, cater for different students who have different learning styles, find and create teaching materials, develop skills through exposure to existing on-line sources and create a motivating environment that is conducive for learning.

Vildan Karpuz,AslGktürk,Meral Koyutürk
Marmara Medical Journal , 2007,
Abstract: Objective: The outcomes of ICSI (Intracytoplasmic Sperm Injection) treatments were evaluated and compared with sperm morphology and motility classifications in order to determine whether strict criteria or motility could aid in predicting the ICSI outcomes.Materials and methods: The infertile couples admitted to the clinic, 242 of them were selected and ICSI treatment was performed. In study group, female partners required having at least 5 oocytes at metaphase II and for male partners only the presence of spermatozoa cells in the semen fluid was necessary. Semen analysis and motility was performed according to WHO (World Health Organisation) criteria and sperm morphology was assessed according to Kruger’s criteria.Results: There was no significant difference for the ICSI outcome assessment parameters indicated that fertilization and pregnancy rates between in the groups based on the percentages of sperms morphology and motility.Conclusion: Sperm morphology and motility were accepted as best parameters to evaluate the outcomes of IVF (In Vitro Fertilization). However, our results showed that ICSI outcomes were independent from these valuable parameters for IVF.

Abstract: Objective: We aimed to evaluate coronary blood flow by means of the TIMI (Thrombolysis in Myocardial Infarction) frame count in patients with idiopathic dilated cardiomyopathy who had angiographically proven normal coronary arteries and compare the results with those of healthy subjects.Methods: This retrospective study included 62 patients with idiopathic dilated cardiomyopathy (34 men, 28 women; mean age 59.7±10.6 years) and 62 control subjects without dilated cardiomyopathy (28 men, 34 women; mean age 56.6±9.8 years). All patients and control subjects had angiographically proven normal coronary arteries. Dilated cardiomyopathy patients had a left ventricular ejection fraction <45%. The TIMI frame count was determined for each major coronary artery in each patient. Statistical analysis was performed using Student’s t test, Chi-square test and Pearson correlation analysis. Results: The TIMI frame counts for each major epicardial coronary artery were found to be significantly higher in patients with idiopathic dilated cardiomyopathy compared to control subjects (corrected TIMI frame count for left anterior descending coronary artery: 37.0±12.5 vs 28.7±11.6, respectively, p<0.001; left circumflex coronary artery: 37.7±12.1 vs 31.0±12.5, respectively, p=0.003; right coronary artery: 37.4±12.6 vs 30.7±11.6, respectively, p=0.003). Mean TIMI frame count had significant although weak positive correlation with left ventricular end-diastolic diameter (r=0.350, p<0.001) and left ventricular end-systolic diameter (r=0.358, p<0.001). Conclusion: We have shown that patients with idiopathic dilated cardiomyopathy and angiographically normal coronary arteries have higher TIMI frame counts for all three coronary vessels, indicating impaired coronary blood flow, compared to control subjects without dilated cardiomyopathy.
Interactive Data Mining for Molecular Graphs
Burcu Y lmaz,Mehmet G ktürk
Journal of Analytical Methods in Chemistry , 2009, DOI: 10.1155/2009/502527
Abstract: Designing new medical drugs for a specific disease requires extensive analysis of many molecules that have an activity for the disease. The main goal of these extensive analyses is to discover substructures (fragments) that account for the activity of these molecules. Once they are discovered, these fragments are used to understand the structure of new drugs and design new medicines for the disease. In this paper, we propose an interactive approach for visual molecule mining to discover fragments of molecules that are responsible for the desired activity with respect to a specific disease. Our approach visualizes molecular data in a form that can be interpreted by a human expert. Using a pipelining structure, it enables experts to contribute to the solution with their expertise at different levels. In order to derive desired fragments, it combines histogram-based filtering and clustering methods in a novel way. This combination enables a flexible determination of frequent fragments that repeat in molecules exactly or with some variations.

Abstract: While the total private final consumption expenditures in Turkey has increased with anaverage of 67,2% in the last 15 years, the consumption expenditures made through the credit cardhave increased with an average of 104,3% per year. In this study, it is researched that to whichextent does the expenditures made through credit cards in Turkey, regarding the other factors,affect the total private final expenditures in Turkey. To do this, a multi-regression analysis isperformed by taking the factors affecting consumption expenditures, disposable income, marketinterest rates, consumption expenditures made through credit cards as independent, and takingtotal private final consumption expenditure as dependent variable. In the analysis 15-year seriesare used. The first differences between the series are taken to have new series and regressionanalysis is refined from time effect. According to the analysis results, the first factor increasingthe total private final consumption expenditure is credit cards and the next is disposable incomewhereas the inflation and the interest rates are not found as important.

Yüksek??retim ve Bilim Dergisi , 2012,
Abstract: In this study, higher education administrators, administrative behaviors; as educator, leader and manager, emotional competency; as self awareness and self management and social competency; as social awareness and social skills were compared according to two different cultures. The data was collected by inventories from 165 educators, and head of the departments Istanbul, and Helsinki Universities in 2008-2009 educational year. Elkins' administrative behaviors of higher education administrators inventory and Goleman's emotional and social competence inventory were conducted to test the differences. The manager behaviors of Istanbul University administrators are significantly higher than University of Helsinki administrators. The emotional competences of University of Helsinki administrators are significantly higher than the administrators of Istanbul University in the dimensions of self-awareness, self management, emotional selfcontrol, achievement orientation and positive outlook. The social competencies of University of Helsinki administrators are significantly higher than the administrators of Istanbul University in the dimensions of social awareness, empathy, and conflict management. On the other hand, the social competencies of Istanbul University administrators are significantly higher than the administrators of University of Helsinki in the dimensions of organizational awareness, coach and mentor, influence and teamwork. There is a significant positive relationship between the leadership behaviors and emotional and social competencies administrators in both Istanbul University and University of Helsinki. Significant differences are found between faculties and administrators about the administrative behaviors and emotional and social competences of administrators both at stanbul University and University of Helsinki.

Grasas y Aceites , 2007,
Abstract: The objective of this study was to determine the nutrient and antioxidant contents of grape seed and pomace oil extracts from the main Turkish wine grape cultivars, Kalecik karas1, Narince, Hasandede and Emir. Dried and powdered seed and pomace materials were extracted with hexane. The results showed that the oil concentration of seeds ranged from 12.35 to 16.00% while in pomace the oil concentration varied from 5.47 to 8.66%. Grape seed and pomace oils were rich in oleic and linoleic acids and the degree of unsaturation in the oils was over 85%. α- tocopherol was the most abundant tocopherol in the oil extracts. Although γ and δ-tocopherols were found with low concentrations, β-tocopherol was not detected in the oil extracts. Oil extracts from pomace in all cultivars gave the highest tocopherol contents compared to the seeds. The contents of total phenolics were higher in pomace oil extracts than seed oil extracts. The highest total phenolic content (392.74 mg/kg) was found in the oil extract from Narince pomace compared to the other oil extracts. The refractive indexes of pomace oil extracts ranged from 1.445 to 1.468 while the refractive indexes of the seed oil extracts ranged from 1.460 and 1.466. In conclusion, wine byproducts including the seeds and pomace can be utilized both to get natural antioxidants and to obtain edible vegetable oil. El objetivo de este estudio fue determinar los contenidos de nutrientes y antioxidantes de extractos de aceite de orujo y pepita de uva de los principales cultivares de uva de Turquía, Kalecik karas1, Narince, Hasandede y Emir. El material procedente del orujo y las semillas, seco y pulverizado, se extrajo con hexano. Los resultados mostraron que la concentración de aceite de las semillas osciló entre 12,35 y 16,00 % mientras que en el aceite de orujo la concentración varió entre 5,47 y 8,66%. Los aceites de orujo y pepita de uva eran ricos en ácido oleico y linoleico y su grado de instauración fue de un 85%. El α-tocoferol fue el tocoferol más abundante en los extractos. Aunque también se encontraron γ y δ-tocoferol a bajas concentraciones, no se detectó la presencia de β-tocoferol. Los extractos de aceite de orujo mostraron el contenido de tocoferol más alto comparado con las semillas en todos los cultivares. Los contenidos de fenoles totales fueron más altos en los extractos de orujo que en los de semillas, encontrándose el valor más alto (392,74 mg/kg) en el extracto de orujo del cultivar Narince. Los índices de refracción de los extractos de aceite de orujo variaron de 1,445 a 1,468 mientras que los de semi

Abstract: Aim: Appropriate antibiotic use for urinary tract infection (UTI) will provide protection against antibiotic resistance and complications including renal parenchimal damage and reflux nephropathy which may occur in the future. This study aimed to show the distrubition of community-acquired gram negative microorganisms in the region of Konya and the change in antibiotic resistance rates in time. Material and Method: Patients between 0 and 17 years of age with a positive urine culture between July 2003 and January 2010 were included in the study. 2544 positive cultures were obtained from a total of 1742 patients. Results: Female patients costituted 57.6 % of the patients who had positive urine culture. Microorganisms isolated from infected female and male patients included E coli (76.1 and 41.9%), Klebsiella spp (13.7 and 24.3%), Proteus spp (6.9 and 28.4%) and the others (3.4 and 5.2%). E.coli, Klebsiella and Proteus species were found to be sensitive to carbapenems, aminoglycosides, quinolones and third generation cephalosporines. High trimetoprim-sulphametoxasol (TMP-SM) resistance in the E.coli and Proteus groups (48.2%-48.5%) and high ampicillin resistance (68.9-88.2%) in the E.coli and Klebsiella groups were remarkable. For all three microorganisms an amikacin sensitivity of 100% was found. When antibiotic sensitivities were compared between the periods of 2003-2006 and 2006-2010, resistance rates of microorganisms against many antibiotics were found to be increased significantly. Conclusions: These data suggested that the microorganisms causing UTI were susceptible to aminoglycosides and third generation cephalosporins. The apparent increase in the resistance rates over a relatively short period was a precarious circumstance. Trimethoprim-sulphamethoxazole and ampicilline should not be the first choice for treatment of UTI because of high resistance rates. (Turk Arch Ped 2012; 47: 107-13)
Germination of Anatolian Black Pine (Pinus nigra subsp. pallasiana) Seeds from the Lakes Region of Turkey: Geographic Variation and Effect of Storage

Abstract: Effects of 10-year storage on germination of seeds in 191 Anatolian Black Pine trees from 23 populations in the Lakes Region of Turkey were investigated. Germination tests were conducted with both fresh (in year 1999) and stored (in year 2009) seeds and variation in germination was related to geographic features of the populations. Significant reductions in germination rate (from 79.93% to 30.68%) and germination percentage (from 95.99% to 58.41%) were observed after 10-year storage. Germination characteristics seem to be associated with humidity of population locations. Seeds from more inland (i.e., continental) populations germinated slower but attained higher germination percentage for both seed sets. Germination percentage of stored seeds is highest at elevations with high humidity. Greater attention should be given to environmental conditions of seed sources in storing Anatolian Black Pine seeds in the Lakes Region of Turkey as it is a very important tool in ensuring continuous seedling production and genetic conservation.
