본 연구는 볼링 투구동작의 성패는 스텝과 스윙이 결정한다는 가정 하에 어프로치에서의 동작에 주안점을 두고, 볼링선수를 대상으로 자유로이 투구를 하게 하고 피험자 본인이 잘되었다고 판단하는 동작과 잘못되었다고 판단하는 투구 동작을 비교 분석하는 것이 본 연구의 목적이다. 투구동작시 어드레스에서부터 릴리즈까지의 동작을 각 스텝별로 국면을 설정하고, 3차원영상분석을 실시하여 각 스텝별로 보폭, 신체중심의 위치, 볼의 위치를 성공과 실패동작으로 나누어서 비교 분석하였다. 보폭은 성공과 실패동작에서 큰 차이를 보이지 않았으며, 4국면과 5국면에서의 보폭이 실패동작에서 크게 나타났다. 신체중심의 위치에서도 큰 차이를 보이지 않았으나 성공시가 실패시보다 상하 이동폭이 작게 나타났다. 볼의 위치는 성공과 실패시 모두 스텝중에는 3국면이 가장 낮게 나타났으며, 상하 이동폭이 적은 안정적인 투구를 하는 것으로 나타났다.

The purpose of this study is to examine the state of utilization in sport facilities at a university and drew up the improvement plan for all students. To accomplish this work, the survey of the 445 students(male 221, female 224) were collected. The collected data were analyzed through the frequency analysis. All of sports facility is used for wide range of student who like to use as their leisure in order to learn variety experience for spending their spare time. Also sports facility of university accomplish social education function to all member of university. Having sports facility for university can also work as a promotion and new impression to people its university image as well as welfare for staff. Especially, excellent sports facility at university can provide public service to local people where university is located. Having sport facility at university is directly related to development of university in many way, university is required to implement effective program for operating sport facility at university.

Objective: The purpose of this study was to investigate the feasibility of a new vault technique through a kinematic comparison of the YANG Hak Seon and Yeo 2 vaults. Method: The photographic images of the YANG Hak Seon and Yeo 2 vaults were collected using a high-speed camera, and their kinematic characteristics were analyzed using three-dimensional image analysis. Results: During the post-flight phase of the Yeo 2 and YANG Hak Seon vaults, the time of flight, height of flight, and flight distance were similar. At the peak of the post-flight phase, the trunk rotation angle of the YANG Hak Seon vault rotated $457^{\circ}$ more than did the Yeo 2 vault. During the post-flight descending period, the twist velocity of the trunk was much faster with the YANG Hak Seon vault ($1,278^{\circ}/s$) than with the Yeo 2 vault ($1,016^{\circ}/s$). Conclusion: To succeed in the new technique, the average twist velocity during post-flight must be maintained at $1,058^{\circ}/s$ and the twist velocity must be increased from the ascending phase.

Purpose: This study aims to analyze the management environment Provincial and Municipal Professional Soccer Teams based on financial statements at a time when strengthening the financial soundness of domestic professional soccer teams is emphasized. Research design, data, and methodology: This study was sampled using convenience sampling and a total of 607 questionnaires were used. In this study, questionnaires were used as a survey tool, consisting of eight questions in a total of four areas, measuring demographic characteristics, shoe design, shoe functionality, shoe price, and promotion. Results: First, the importance of outdoor brand shoe selection attributes was high in cost-effectiveness, discount, and promotional models, while the satisfaction level was high in shoe size, content, and Model. Second, IPA analysis revealed shoe sizes, promotional models, and discount factors as maintenance and management continuation areas. Content factors have emerged as a competency-focused area. A sense of cushioning and wearing has emerged as an area of further improvement. As a status quo area, shoe laces and cost-effectiveness factors appeared. Conclusions: First, consumers considered the cost-effectiveness of choosing shoes, followed by discounts, and efforts are needed to diversify promotional content to maximize promotion for shoe sales. 3. Domestic outdoor brands are not yet satisfied with consumers.

Purpose: This study was to investigate the effect of a 12-week plyometric training on body composition, physical fitness and bone mineral density in obese male adolescents. Method: Twenty adolescent boys who are obese were randomly assigned to a control group (CON, n=10) or plyometic exercise group (EXE, n=10). The EXE group was performed 3 times per week for 12 weeks. The body composition, physical fitness, and bone mineral density were measured before and after the 12 weeks intervention. Results: The results of this study were as follows: i) In EXE group, the fat mass was significantly decreased between pre and post, whereas the difference of the body weight, BMI, and LBM were not significant. ii) Among the physical fitness factors, grip strength, muscular endurance, and 2 0m shuttle running were significantly improved but flexibility did not show any significant difference. iii) The bone mineral density was significantly improved between pre and post in EXE group. Conclusion: These results suggested that plyometric training for 12 weeks may be effective in improving body composition, physical fitness, and bone mineral density in obese adolescents. Further implications were discussed.

In order to find out the factors influencing students' willingness to continue exercise and increase their willingness to continue exercise, I conducted an investigation on Chinese college students' motivation to exercise and to improve their healthy lifestyle. Through a questionnaire survey of 312 Chinese university students, the motivation of sports participation, the promotion of healthy lifestyle and the willingness to continue exercise were measured. The questionnaire data were collected from November 2021 to January 2022. The questionnaires were collected and processed by SPSS, and the analysis methods were frequency analysis, reliability analysis and linear regression analysis. The results show that there is a significant relationship between the motivation of exercise and the healthy lifestyle of Chinese college students and the persistence intention, and the limitations of this study and suggestions for future research are discussed.

해외의 선진국 사례를 중심으로 스포츠시설 안전관리 네트워크 및 시스템 현황을 분석하여 한국 스포츠시설 안전관리 법적 규제를 마련하고, 안전관리 매뉴얼을 구축하는데 중요한 기초 자료를 제공하는 데 목적이 있다. 또한 스포츠시설 안전관리에 대한 정보를 토대로 각국의 스포츠시설 안전관리 시스템과 대처방안에 대한 구체적인 벤치마킹을 실시하였다. 그 결과, 미국은 국토안보부(DHS)를 필두로 국가의 안전을 위협하는 것으로부터 수호하고자 하는 포괄적인 국가 전략을 감독하고 조직화하고 있는 것으로 나타났다. 독일은 법 규정의 제도화, 스포츠시설 안전 가이드라인, 스포츠시설 안전관리전문가 육성시스템 등 미국과 호주보다 더욱 현실적이고 입체적인 대안을 마련하고 있다. 호주는 주요위험시설(MRF)의 운영자들에게 실용적인 지침을 제공하고 있으며, 특히 비상사태 운영시스템(EMS)을 통해 대규모 재난뿐만 아니라 위험 물질 등에 대한 계획과 협력을 다루고 있다.

Design patent is a type of industrial design right that is granted on the ornamental design of a functional item. We analyzed domestic design patents that were applied from 1965 until 2008, to the field of functional clothing. Since the year 2000 the number of design patents of functional clothing progressively increased. Design patents applied to the functional clothing field includes sport wear (47%), working clothes (34%), and leisure wear (19%). Design development of the sports wear from the latter half of 1990's has shown a continuously increasing tendency. The most patent applications belonged to the companies(51.4%), followed by individual applicants (46.6%), and the universities or laboratories had the least number of applications (2.0%). In case of working clothes or the leisure wear, the number of design applications focusing on the functional characteristic is higher than that of aesthetic characteristic, however, the number of design applications focusing on the aesthetic characteristic is higher in sportswear.
