THE EFFECTS OF MICROTEACHING PRACTICES ON PRE-SERVICE PHYSICAL EDUCATION AND SPORT TEACHERS’ ATTITUDES TOWARDS TEACHING PROFESSION

The present research is a descriptive study, conducted in order to define the effects of microteaching practices on pre-service physical education and sports teachers’ attitudes towards teaching profession. The research was conducted on 60 individuals, who studied at Gaziantep University, Department of Physical Education and Sports Teaching and took Special Teaching Methods II course in 2015-2016 academic year. In order to collect data for the present research, “Attitude Scale towards the Profession of Teaching” developed by Üstüner (2006) was employed. For data collection, a 13-week microteaching practice was implemented on pre-service physical education and sports teachers. Data collection tool was implemented on the work group twice, before and after the implementation. Collected data were analysed on SPSS 22.0 program. Paired-Samples t test was utilized as the statistical method. According to the obtained findings, pre-service teachers’ attitudes towards teaching profession are high (positive), and microteaching practice affected pre-service physical education and sports teachers’ attitudes towards teaching profession positively.   Article visualizations

THE EVALUATION OF HIGH SCHOOL 12TH GRADE STUDENTS’ OPINIONS ABOUT THE EFFECTIVENESS OF PHYSICAL EDUCATION CLASSES

The present study is conducted to identify 12th grade high school students’ opinions about the effectiveness of physical education classes. In the study, the interview method of qualitative research method is used. In order to obtain data of the study, open-ended questions that are designed to evaluate students' views and suggestions are used. These questions are following: (1) How do you find the teaching of the lesson, (2) What are the achievements of the course, (3) What are popular and unpopular aspects of the lessons, (4) How do you relate these classes with other courses, (5) What are your recommendations in terms of how to do the class. The research group was formed with 50 students who are studying in the 12th grade in official high schools depending on Gaziantep Directorate of National Education. Content analysis is applied to the data obtained from student’s opinions. Consequently, considering high school 12th grade students’ opinions about physical education classes, it can be said that physical education classes are effective and efficient. It is identified that students think physical education classes are important as they contribute to the development of physical, psychological and social aspects of human beings. However, the number of class hours and environmental conditions are not sufficient enough so this affects the effectiveness of the classes negatively.  Article visualizations

For this purpose, in 2008, mechanization level of farms in 11 villages and 121 plants was based on simple random sampling method. According to study results, it was found that number of tractor per plant was 0.74, number of agriculture machine per tractor was 4.53, mean tractor power was 34.71 kW, tractor power per unit area was 30.18 kW/ha, number of tractor per 1,000 ha was 869.56, area per a tractor was 1.15 ha, and machine mass per tractor was 2.61 tons

Is There a Change in the Treatment of T1 Glottic Cancer After CO2 Laser? A Comparative Study with Cold Steel

Objective: Carbon dioxide (CO2) laser provides high local control and disease-specific survival rates with minor morbidity and good quality of life in transoral cordectomy. We aimed to compare the oncological outcome and survival between cold steel and CO2 laser in the treatment of early glottic cancer.Methods: In this retrospective study, the participants were divided into two groups. The first group comprised patients who were operated upon between 2001 and 2007 using cold steel (group 1, n=38), and the second group comprised patients who were operated upon between 2008 and 2016 using CO2 laser (group 2, n=88). Both groups were compared regarding age, gender, pathological grade, T stage, type of cordectomy, margin status, anterior commissure involvement, follow-up, locoregional recurrence, and disease- free survival (DFS).Results: The overall survival rate and DFS were similar between the two groups (94.7% vs. 98.9% and 100% vs. 98.9%, respectively), and no association was found between surgical margin positivity and local recurrence. However, a significant association between the presence of anterior commissure involvement and recurrence was found in all 126 patients (p=0.016). Local recurrence was significantly higher in the group 2 (p=0.024), but it did not affect overall survival and DFS in these patients (100% vs. 94.1%).Conclusion:Although CO2 laser excision is considered to be superior to cold steel regarding surgical time and bleeding control, the local recurrence rates were found to be higher with the laser than the cold steel. Thus, we argue that cases should be selected more carefully concerning the anterior commissure, depth of tumor invasion lateral to vocal muscle, difficulty at endoscopic exposure for lesions with anterior commissure involvement, and reliability of surgical margins at frozen sections

Why Do We Not Need CT in Patients Who Undergo Type I Tympanoplasty?

Objective:High-resolution computed tomography (HRCT) has gained wide acceptance in diagnostic work-up of suppurative chronic otitis media. Most ear surgeons order HRCT to make a rational operative plan, especially in the presence of symptoms, such as refractory otorrhea with bad odor, epithelial debris at retraction pockets, and defects in bony walls of the middle ear. The aim of this study was to show the lack of necessity of preoperative HRCT by evaluating its predictive value in patients who underwent type I tympanoplasty.Methods:The study included a patient group who underwent tympanoplasty with dry perforation and normal middle ear mucosa. The intraoperative findings of 43 patients were compared with preoperative HRCT and audiogram findings.Results:There was no significance between preoperative air conduction threshold and existence of ossicular erosion in HRCT. HRCT incorrectly predicted the presence of cholesteatoma in two patients. The positive predictive value of HRCT in detecting soft or granulation tissue was 4/14 (28.57%). The sensitivity and specificity of HRCT in the diagnosis of ossicular chain status were 9.09% and 90.62%, respectively.Conclusion:HRCT plays an important role in the assessment of patients with suppurative chronic otitis media and cholesteatoma. However, preoperative HRCT in patients who have undergone type I tympanoplasty is not necessary. It has no benefit and also leads patients to unnecessary radiation exposure

Signature Recognition and Verification with ANN

In this paper, we present an off-line signature recognition and verification system which is based on moment invariant method and ANN. Two separate neural networks are designed; one for signature recognition, and another for verification (i.e. for detecting forgery). Both networks use a four-step process. First step is to separate the signature from its background. Second step performs normalization and digitization of the original signature. Moment invariant vectors are obtained in the third step. And the last step implements signature recognition and verification
