This study aims to investigate the relationship between linear speed, agility and reaction time in amateur football players. Totally 15 male amateur soccer players with an average age of 20.00 ± 1.309 (years), average height 1.78 ± 0.058 (m), bodyweight average 70.05 ± 6.300 (kg) and body mass index average 22.18 ± 1.525 (kg / m2) voluntarily participated in the research. All participants completed a test battery involving linear sprinting (10, 20, 30 m), agility test (T test) and reaction time test. Fitlight TrainerTM device was used in all experiments. Pearson correlation analysis was performed to determine the relationship between linear speed, agility and reaction time. As a result of the investigation, statistically significant positive relationships were found between the reaction time and 10 m and 20 m linear speed, between agility and 20 m and 30 m linear speed, between 10 m and 20 m linear speed and between 20 m and 30 m linear speed ( p <0.05). As a result, according to this study, it can be said that features such as linear speed, agility and reaction time are related to each other in amateur soccer players.

Bu çalışmanın amacı altın ons fiyatları ve ham petrol fiyatları ile Borsa İstanbul Ulusal 100 endeksi arasındaki uzun dönemli ilişkilerin incelenmesidir. Bu bağlamda 1997-2014 yılları arasına ait toplam 3703 günlük verilerle çalışmıştır. "Genişletilmiş Dickey Fuller ve Philips Perron Birim Kök Testleri" sonucunda veriler birinci farklarında durağan çıkmış daha sonra "Johansen Eşbütünleşme" analizi ile değişkenler arasında uzun dönemli ilişkiyi gösteren bir adet vektörün var olduğu ortaya çıkmıştır. Ancak, araştırma modelimiz olan altın ons fiyatları ve ham petrol fiyatlarıyla hisse senedi fiyatları arasındaki uzun dönemli ilişkiyi gösteren vektör hata düzeltme teriminin katsayısı anlamsız çıkmış ve değişkenler arasında uzun dönemli bir denge ilişkisi kurulamamıştır. Bu sonuçlar altının günümüzde hisse senetlerine alternatif bir yatırım aracı olarak kullanıldığının göstergesidir.

The purpose of this research; In the 2021-2022 academic year, based on the opinions of the principals working in primary, secondary and high schools in the city center of Tokat, it is aimed to reveal whether the principals have the necessary knowledge and skills for inspection, the problems they encounter in inspection, and the positive and negative aspects of inspection. The data used in the research were collected from a total of 18 people, including 6 primary school principals, 6 secondary school principals and 6 high school principals, selected according to the maximum diversity sampling, working in the central primary, secondary and high school in Tokat province. The data collected with the standardized open-ended interview form developed by the researcher were analyzed and interpreted using the content analysis approach, one of the qualitative data analysis approaches. According to the results of the research, most of the participants argued that it is a correct practice to carry out the supervision by the school principals. The participants stated that the supervision by the school principals puts pressure on the teachers and students, and the teacher-principal relations are negatively affected. It has been concluded that the positive aspects of supervision by school principals are that teachers keep themselves up-to-date on the program and content and contribute positively to their professional development. It was emphasized that the negative aspects of supervision by school principals would damage the developed relations between the supervisor and the supervisor. This situation also emphasized the damage to the institutional balance and school culture, and the psychological pressures that the supervision itself will create on teachers.
