허리케인 지진 등을 미리 예측하거나 택배와 같은 운송도 가능하다. 다이어트를 원하는 사람들에겐 개인 트레이너가 되기도 하고 양떼를 모는 양치기 역할을 맡을 수도 있다. 과학 군사 마케팅 스포츠 엔터테인먼트 등 그 어떤 분야에서도 활용할 수 있다. 2014년 세계적인 미래학자 토마스 프레이가 발표한 '192가지 미래 드론 활용법'에 언급된 내용들이다. 최근 세계적으로는 물론이고 국내에서도 '드론'이 뜨거운 관심을 얻고 있다. 활용 범위가 광범위한 만큼 향후 산업화된다면 그 잠재력 또한 무궁무진하기 때문이다. 과연 드론은 '황금 알을 낳는 거위'가 될 수 있을까.

The purpose of the study is to examine sports-related cognitive functions through a systematic review and to suggest effective instruments to measure the cognitive functions. The present study was conducted based on the systematic review and meta-analysis protocol-the PRISMA. Of 429 articles searched through keywords from 2008 to 2020, 45 articles that met the selection criteria were analyzed. It was revealed that athletes had better cognitive functions than non-athletes, that the higher the sports expertise was, the higher the cognitive functions, and that there were differences in cognitive functions according to the sport types. The primary cognitive functions related to sports performance summarized as executive functions (inhibition ability, cognitive flexibility), information processing speed, spatial ability, and attention. As tasks for measuring each cognitive function, a stop signal task for inhibition ability, a design flexibility task for cognitive flexibility, a simple and choice reaction time test for information processing, a mental rotation task for spatial ability, and an attention network test for attention are appropriate.

The purpose of this study is to examine the structural relationship among professionalism of sport instructors, job burnout and turnover intention. Independent variable was professionalism of sport instructors, mediating variable was job burnout. Finally, dependent variable was turnover intention. The data were collected from 253 sport instructors of elementary school by the convenience sampling method. This study used IBM SPSS Ver. 20.0 and AMOS 18.0 for frequency analysis, reliability, correlation analysis, confirmatory factor analysis and structural equation model. After confirming the test of goodness of fit of a model, individual hypotheses was verified. The results were as follows; First, Professionalism had a significant influence on job burnout. Second, Job burnout had a significant influence on turnover intention. Third, Professionalism did not have a significant influence on turnover intention.

The purpose of this study is to conceptualize the process of formation by the exploration of the lives of professional golfers who grow to excellent sports leaders, categorize the concept and suggest models between categories. In order to reveal in depth the change process of the job formation, the 'grounded approach' as a qualitative study was used as a the methodological frame of this study, and snow sampling, one of nonrandom sampling was used for the selection method of the study participants. 10 study participants who are able to make positive self-expression and talk with the researcher were selected. Through grounded approach appropriate for this process research, this study could acquire following results. First, through the casual condition that is the exploration of the lives of professional golfers growing to excellent sports leaders, it connected to the central phenomena of professional instruction methods and education belief as golf leaders. In this process, the changes as new experiences for the charm of the new job and relationship formation influence as the function of a contextual condition. In addition, golf leaders tried to become a more completed golf leader through self-efforts for development and expertise attainment according to the their own situations as well as belief, and they have established the lives of firm golf leaders through the process. Second, as a result of the changes of their lives as professional golfers growing to excellent sports leaders, the paradigm of grounded approach which is abstracted as total 141 concepts, 17 subcategories, and 11 superordinate categories were composed.

The purpose of this study is to analyze the relationship between students' motivation for participating in leisure sports, students' physical self-concept and the life satisfaction of university students. A total of 419 students were finally analyzed using the convenience sampling method of non-random sampling method after selecting those university students participating in leisure sports at a university located in J district. The results of analysis using SPSS version 21.0 program are as follows. First, there is a positive (+) correlation between the motives of participation of university students and their physical self-concept and satisfaction with university life. Second, the influence of the motive to participate in sports has a positive (+) effect on sports competence and this is affected by health fitness and social interaction, physical activity is affected by pleasure, health fitness, and conditioning, self-esteem, muscular strength is affected by pleasure, health fitness, condition, and society, flexibility is affected by pleasure, health fitness, and society. Third, the influence of participation motive had a positive (+) effect on school satisfaction is affected by pleasure, health fitness, physical condition, external display, socialization, and fellow satisfaction is effected by pleasure and condition.

Repetitive overhead throwing exerts significant mechanical stress on the elbow joint. Pitching in baseball, serving in tennis, spiking in volleyball, passing in American football and launching in javelin-throwing can all produce elbow pathology by forceful valgus stress, with medial stretching, lateral compression and posterior impingement. This stress can lead to developmental anatomic changes in the young thrower. Asymptomatic pathology in the shoulder and elbow joint is prevalent and, with overuse, can progress to disabling injury. Joint injury occurs as a result of the body's inability to properly coordinate motion segments during the pitching delivery, leading to further structural damage. The implications of acute and overuse injuries and the possibility of permanent damage should be understood by parents, coaches and the athletes. Proper understanding of the intrinsic and extrinsic risk factors that could lead to elbow injuries is thus required. Measures to prevent elbow injuries should include proper coaching, warm-up, medical expertise and protective gear. Injury prevention and rehabilitation should center on optimizing pitching mechanics, core strength, scapular control, and joint range of motion.
