To achieve the objective of this study, the data was collected from 300 trainees of security martial arts gyms located in Seoul, Incheon, and Gyeonggi-do regions by using the convenience sampling method. Total 281 questionnaires were used for the analysis after excluding 19 questionnaires. Using the SPSS 23.0 for data-process, this study conducted the frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis. First, all the variables showed positive(+) correlations. Second, the presentation of vision of instructors' servant leadership had positive(+) effects on the behavioral commitment while the devoted attitude of instructors' servant leadership had positive(+) effects on the cognitive commitment. Third, the presentation of vision, formation of community, and support for growth of instructors' servant leadership had positive(+) effects on the psychological elements while the presentation of vision and support for growth had positive(+) effects on the environmental elements. The presentation of vision and formation of community had positive(+) effects on the physical elements while the presentation of vision and formation of community had positive(+) effects on the educational elements. The presentation of vision, formation of community, and support for growth had positive(+) effects on the social elements. Fourth, both cognitive commitment and behavioral commitment out of trainees' exercise commitment had positive(+) effects on the psychological elements, environmental elements, physical elements, and educational elements of training satisfaction while only the cognitive commitment had positive(+) effects on the social elements.

PURPOSE: This pre-post intervention study aimed to examine the effects of a 12-week supervised modified Taekwondo exercise program on the functional fitness of community-dwelling older adults. METHODS: 10 participants (mean age: 72.3 ± 4.6 years) completed the program over a 12-week period. The intervention consisted of Taekwondo-based exercises modified for older persons. Changes to functional fitness were measured using the finger-to-nose test, functional reach test, timed up and go test, 30-second sit-to-stand test, 30-second arm curl test, Chester step test, chair sit-and-reach test, and back scratch test. Participants were assessed prior to the training and after the final training session, changes were measured using descriptive statistics and paired sample 't' tests. RESULTS: Effect sizes ranged from small to large (Cohen's d = .22 to 1.23). The exercise program was well- tolerated by participants, with a high level of engagement and no attrition for the duration of the program. Results showed significant improvements in most measures of functional fitness (p < .05) except for the back scratch test (p = .051). CONCLUSION: These findings suggest a well-designed, supervised, modified Taekwondo exercise program can significantly improve functional fitness in older adults.

This Paper aims to explore the key factors that drive box-office success in Korean, Chinese and Japanese film market regarding to the storytelling of the movies. At first, I researched the top 20 movies at the box office of Korean, Chinese and Japanese film market from 2007 to 2011.And then I tried to figure out the key factors for the success and the differences among those countries. Usually the purpose of the movie planning in Korea is for the domestic market. In the profit structure of Korean film industry, it is really hard to focus on the overseas film market. In Chinese film market, recently it has been changed a lot especially film genre. The movie liked to watch is melodrama, romantic comedy movie It is being changed to the comedy genre from the war and martial arts movie. And it is emphasized the importance of the scenario in the film production. They want to watch their lives like a real and dreams at the movie and the movie tries to show this trend. In Japanese film market, they made movies in which TV drama, animation and cartoon according to the O.S.M.U. strategy. The movies like to watch are the blockbuster movies, horror movies, thriller movies and melodrama. Comparing with Korea and China, they like movies which show more fantastic and fairy tale imagination.
