Examination of the leisure satisfaction levels of individuals partaking in recreational activities

The objective of this study is to examine the opinions of the individuals partaking in recreational activities on their leisure satisfaction levels in consideration of different variables. A total of 220 public employees, 150 (68.2%) of whom were "Male" and 70 (31.8%) of whom were "Female" selected by purposeful sampling method participated in the study voluntarily to this end. Screening model was utilized in the research. The sample of the study comprised the public employees of Avcılar district municipality of Istanbul province. In addition to the personal information form created through the researcher, "Leisure Satisfaction Scale" developed by Beard and Ragheb (1980) and adapted to Turkish through Karlı et al. (2008) was employed as data collection tool in the research. Percent (%) and frequency (f) methods were utilized for determining the distribution of personal information of participants while the Shapiro–Wilk test of normality was conducted with an eye to determine if the data had normal distribution and subsequently Mann -Whitney U-test and Kruskal-Wallis test were applied to determine the significant differences after it was understood that the data were appropriate for non-parametric test conditions. Male participants had a higher score than female participants in the "Psychological" and "Education" subscales of the leisure satisfaction scale in terms of gender. The scores achieved through participants aged 40 years and over are higher the scores of participants in other age groups, in the "Relaxation" subscale of the leisure satisfaction scale in terms of age. No significant difference was found in the subscales of the leisure satisfaction scale according to the monthly income variable. As a result, it was concluded that gender and age were significant factors in leisure satisfaction levels while monthly income was not a significant factor

INVESTIGATION OF TRANSFER OF NATURALIZATION OF ATHLETES IN THE OLYMPIC GAMES ACCORDING TO SPORT SCIENCES STUDENTS

In today's globalizing world, unlike others, only a few countries and industries have remained or have opted out of globalization. Globalization shows its effects in sports. The desire of the countries to be more successful in international sports competitions, making athletes of different nationalities their citizens and entering them to the competitions constituted the concept of naturalization of athletes. Whether the successes of the naturalized athletes are ethical or whether these athletes prevent the development of domestic athletes is constantly on the agenda. From this point of view, our research focuses on the perspectives of university students studying in sports sciences to naturalization of athletes. Total of 891 participants voluntarily participated in the study. The Cronbach's Alpha value of the scale, which was used to find out the opinions of the participants about transfer of allegiance of athletes, was found 0,79. Percentage, frequency, t-test and Anova test were used to evaluate the scale. As a result the participants say that; in the future sports infrastructure development must be support instead of naturalization of athletes and their transfer fee should be used for investment in national athletes’ development. Successes of the naturalization of athletes are the loss of prestige for Turkey. In order to prevent this, sports infrastructure based education programs can be given more importance.  Article visualizations

An Integral Equation Approach For The Solution Of The Stokes Flow With Hermite Surface

Konferans Bildirisi -- Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2013Conference Paper -- Theoretical and Applied Mechanical Turkish National Committee, 2013Üç boyutlu Stokes akışını çözmek amacıyla sınır integral yöntemiyle beraber dörtgen Hermit yüzeyler kullanılarak bir integral denklem yöntemi geliştirilmiştir. Sayısal sonuçlar, sınır sıralama yönteminden ve daimi Stokes denkleminin temel çözümleri olan Stokesletlerin sürekli dağılımından yararlanılarak elde edilmiştir. Dörtgen yüzey elemanları, komşu elemanlar arasındaki yüzey normal vektörünün sürekliliğini sağlayan hermite fonksiyonları kullanılarak tanımlanmıştır. Tekil integraller tanh-sinh tümlev yöntemi, tekil olmayan integraller ise Gauss-Legendre yöntemi kullanılarak sayısal olarak hesaplanmıştır. Sayısal algoritma ilk olarak küre etrafindaki üç boyutlu Stokes akışında doğrulanmıştır. Sonrasında algoritma küresel parçacıkların sedimantasyonu problemi için uygulanmıştır.An integral equation method has been developed to solve the three-dimensional Stokes flow using a quadrilateral Hermite based function approach to the boundary integral method. The numerical solutions are obtained by utilizing the boundary collocation method as well as the continuous distribution of Stokeslets, which are the fundamental solutions of the steady Stokes equations. The quadrilateral surface elements are based on the bi-cubic hermite functions that allows the continuous variation of the surface normal vectors between neighboring elements. The singular integrations are evaluated numerically using the tanh-sinh quadrature rule meanwhile non-singular integrals are evaluated using the Gauss-Legendre quadrature rule. The numerical algorithm is initially validated for the three-dimensional unbounded Stokes flow around a sphere. Then the algorithm is applied to the sedimentation of spherical particles. Keywords: Integral equation method, Stokes flow, Hermite functions, singular integrals, sedimentation

The examination of sport managers and coaches’ stress levels and depressed mood at work in Turkey

This paper is an investigation of stress levels and depressed mood at work in sport managers and coaches. Three different questionnaires were applied to professional sport managers (n=60) and coaches (n=52) in Turkey to regard to potential sources of stress before, during and after competitions. This sample represented approximately 21% of the total professional football, basketball and volleyball clubs in Turkey. The questionnaires used are “Perceived Stress Questionnaire”, “Anxiety-Stress Questionnaire” and “Depressed Mood at Work Questionnaire”. Our findings indicated that: The aim of first questionnaire was to assess perceived stressful situations and results show that general stress levels of managers and coaches are under the average. When we examine the second questionnaire consisting of health, physical condition, tension caused by stress; it is seen that negative effects of these factors increase. At last; according to the depressed mood at work questionnaire which evaluates the physiological conditions related to stress; it’s found out that both managers and coaches aren’t satisfied with their working atmosphere and managers’ unhappiness levels are higher than coaches are

Analysis of Pre-Service Social Sciences Teachers’ Geography Perceptions through Metaphors: Case of Dumlupinar University

The purpose of this study was to try to explain the perceptions of undergraduate students regarding geography concept using metaphors. A total of 192 students studying in the Department of Social Studies at Kütahya Dumlupınar University in the academic year 2014-2015 participated in this research. In the study following questions were searched to answer: (a) through which metaphors do undergraduate students explain the perceptions they have in relation to the concept of geography? (b) Under which categories are these metaphors collected in terms of common properties? The data in the study were obtained depending on students’ answers to this sentence: ‘‘Geography is like... because...’’. In this research, phenomenological pattern were used and the data were analyzed by using content analysis technique. According to the findings of the research; (a) undergraduate students have produced 112 valid metaphors related to the concept of geography in total. (b) These metaphors by being examined in terms of common features were grouped under five different categories. As a result of the survey, it was observed that %15,2 of the students in Social Studies Department perceived the concept of geography as the source of life, %32,2 of them as part of the review of research, %18,7 as a reflection of the natural environment, 15,2% as nature and human interaction, % 18,7 as entertainment factor. As a consequence, the metaphor related to the concept of geography could be used as a powerful research tool in understanding and explaining the perceptions concerning geography concept of undergraduate students

EFFECTS ON THE SURFACE QUALITY IN THE MACHINING PROCESSES OF THE TOOL VIBRATIONS

The problem of surface quality and cutting stability in the machining processes is very important and is strictly connected with the final quality of the product. Therefore, this paper describes a new theoretical model for the dynamic cutting forces of orthogonal cutting in turning. A specific advantage for the presented model is the convenience for vibration prediction. The presented dynamic force model is used to predict variable cutting forces with dynamic cutting between cutting tool and workpiece.  This model is considered two degree of freedom complex dynamic model of turning with orthogonal cutting system. The complex dynamic system consists of dynamic cutting system force model which is based on the shear angle (φ) oscillations and the penetration forces which are caused by the tool flank contact with the wavy surface

Investigation of motivational cluster profiles and physical self perceptions of athletes performing sports at elite level in individual branches: Bireysel branşlarda elit düzeyde spor yapan sporcuların güdüsel küme profilleri ve fiziksel benlik algılarının incelenmesi

The aim of the present study was to determine the motivation cluster and physical self-perception profiles of elite athletes in individual branches based on gender and national team membership variables. A total of 243 athletes in different branches including 121 females (Meanage = 17,06 SDage = 1,883) and 122 males (Meanage = 17,40 SDage=1.99) participated in the study. In order to determine the motivation profiles of the athletes, the Sports Motivation Scale (SMS) was used and the Physical Self-Perception Profile (PSPP) was used to determine the physical perception profiles. Data analysis was conducted with correlation for variables composed of the subscales in both scales, Ward Method was used in hierarchical cluster analysis conducted to determine the motivational cluster profiles of the athletes, and 4 x 5 (Motivational Clusters x PSPP Sub-Scales) MANOVA analysis was conducted to determine the effect of the motivational profiles on physical self-perception of the athletes. Based on the study findings, the motivation types and self-perception profiles of the individual athletes included four motivational clusters. It was determined that the athletes with moderate motivation scored higher points in sports skills and body attractiveness subscales of the PSPP when compared to the athletes in other clusters. There were significant differences between the motivation levels of the athletes favoring the female athletes based on their gender, and based on their participation in the national team. Furthermore, it was determined that the motivation profiles of the athletes did not lead to a significant difference in their physical self-perceptions. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.

The relationship between organizational justice and organizational revenge of physical education and sports teachersBeden eğitimi ve spor öğretmenlerinin örgütsel adalet algısı ile örgütsel intikam (öç alma) eğilimi arasındaki ilişki

The aim of our study is to examine the relationship between organizational justice and organizational feelings of revenge of teachers. The study sample consisted of 207 Physical Education and Sports teachers working in Bursa city (78 women & 120 men).The data was analyzed with a t-test, ANOVA and Pearson correlation. The study results showed that the data related to both the organizational revenge and organizational justice dependent variables had normal distributions in terms of skewness and kurtosis coefficients. The significance levels were set at p < 0.05. There were no significant differences in subdimensions (distributive-, procedural- and interactional-subdimensions) and the Revenge Scale in terms of gender, marital status, age, seniority and different age group variables. However, an ANONA found a significant difference in distributive justice subdimensions with regards to male participants (t= -1.663; p=.048<0.05) and a similar significant difference was found in the organizational revenge concept regarding the agents whose working time covered 1-12 years (F=2.566; p=.038<0.05). On the other hand, the correlational analysis found no significant relationship between agents’ organizational justice perception and organizational revenge tendency(r=-.062; p>0.05).Extended English abstract is in the end of PDF (TURKISH) file. ÖzetAraştırmamızın amacı öğretmenlerin örgütsel adalet algıları ile örgütsel intikam (öç alma) hisleri arasındaki ilişkinin incelenmesidir. Araştırmanın çalışma grubunu; Bursa ilinde görev yapan 78’i kadın, 129’u erkek olmak üzere toplam 207 Beden Eğitimi ve Spor Öğretmeni oluşturmuştur. Araştırmada veri toplama aracı olarak; Stuckless ve Goranson (1992)’ ın geliştirdiği ve Satıcı vd. (2012; 2015)’ nın Türkçe’ ye uyarladığı “İntikam ölçeği” (Nayir, 2015 Güllü ve Şahin, 2016) ile Niehoff ve Moorman (1993) ‘ın geliştirdiği “Örgütsel Adalet Algılaması Ölçeği” (Abbasoğlu, 2015) kullanılmıştır. Veriler; istatistiki yöntemler, t-testi, ANOVA ve Pearson Korelasyon Yöntemi kullanılarak analiz edilmiştir. Toplanan verilerden elde edilen sonuçlara bakıldığında, hem örgütsel intikam (öç alma) hem de örgütsel adalet algısı bağımlı değişkenlerinden elde edilen verilerin çarpıklık (skewness) ve basıklık (kurtosis) katsayılarının normal bir dağılıma sahip olduğu görülmektedir.  Anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Alt boyutlarda (dağıtımsal, adil işlem ve adil etkileşim alt boyutlarında) ve örgütsel intikam ölçeğinde cinsiyet, medeni durum, kıdem süresi, farklı yaş grupları değişkenlerinde manidar bir fark tespit edilememiştir.
