The purpose of this study was to identify biomechanical characteristics of glide and delivery motion of In-Sung Hwang, player who is a member of the national team among the finalists in the men's shot put at the 2010 National Sports Festivals. Three-Dimensional motion analysis using a system of 3 video cameras at a sampling frequency of 60 Hz was performed for this study. During the glide and delivery phase the results showed following characteristics; 1) The glide type was suitable for the short-long technique, but the trajectory of shot at the glide and delivery phase showed a different trajectory pattern with "S-shaped" type of elite players due to many deviating from central axis of the APSS(athletic-plus shot system). 2) Left knee was more flexed during failed trials compared to successful trials but COG was higher. Therefore, the player showed less stability of COG as he may not get enough breaking force at the left foot. 3) Furthermore, it would be required to have strong muscle power at the trunk, throwing arm, and the lower extremity in order to achieve maintain a low projection angle of the release.

As the participation in marine sports activities has increased according to the increased national income, changes in lifestyle, etc., this study explored various values and possibilities towards a sport for all, which are inherent in marine sports, through the literature research with respect to leisure activities, sport for all, and marine sports. As a result of study, marine sports include the functional values, such as leisure satisfaction and welfare function, as a tool to improve the quality of life, which the sport for all may have, and not only have a positive impact on individual lives, but further, can also contribute to raising the level of social well-being. Marine sports are directly experienced physical activities utilizing nature and importantly functioning in human beings' understanding nature; especially, it could be found that they have the high emotion-educational value which could make the right personality formed for the adolescents in modern society, whose unrealistic leisure activities account for the most part of their leisure time. These results suggest that marine sports contain sufficient positive values and possibilities as a sport for all, and the value as a sport for all could be realized which marine sports may have through active participation.

The purpose of this paper was to analyze a social discourse on the enactment of School Sport Promotion Law produced in the media. For this purpose, 73 articles related to the law collected from portal sites such as 'Daum', 'Naver' and 'Yahoo' as well as 'KINDS' were utilized for data analysis. Therefore, it was concluded that a social discourse's feature related to the enactment of the law is a social 'support' discourse calling for the enactment of the law, a 'denunciation' discourse after the rejection at the regular session of the National Assembly, a 'opposition' discourse concerned about the regression of elite sport and a 'wish' discourse expecting the leap and vitalization of school sport. From the holistic point of view, a dominant discourse is the appropriateness and necessity of the enactment of the law. However, smaller but stronger voices of dissent concerning about the decline in the development of elite sport (especially elite sporting success) were raised.

In september 2004, a new pilot certificate scheme referred to as Sport Pilot Certificate was declared official and standardized in the US. The designation of Light-sport aircraft and the details of the relevant pilot certificate policy was announced out of the perception that a new regulation is required to be applied whereby the limitations on the manufacturing process enhancements and current aviation rules are considered the triggering factors. US Federal Aviation Regulation retains a comprehensive range of airworthiness certificates and aircrafts are managed systematically in accordance with FAR 21, 103. The airworthiness are further segregated into sub categories, which allows differentiated management. Korean Aviation Law classify aircraft into five different categories and powered air vehicle that weighs more than 150kg(19liters fuel capacity) for one seat, 225kg for two seats(38liters fuel capacity) while the systems that fall under a specific mass threshold level are known as ultralight vehicle. The research discusses the policy of the sport pilot certificate and the light-sport aircraft ratings announced official by the Federal Aviation Administration in an intuitive fashion with the analysis of the operations providing the evidence as to the viability of adopting the policy in local grounds. Based on the findings, the report discusses the case for introducing the light-sport aircraft and make recommendation on a strategy of applying the policy in Korea with respect to the pilot certificates, safety agenda, and the written test for the pilot certificate, and operating efficiency.

The aim of this study was to investigate badminton smash and drop motion depends on player's level. To perform this study, ten male badminton players were participated: five skilled players (SG, age: $21.6{\pm}1.1$ yrs, height: $181.4{\pm}6.8$ cm, body mass: $72.4{\pm}5.7$ kg, career: $11.2{\pm}1.1$ yrs) and five less-skilled players (LSG, age: $21.2{\pm}1.1$ yrs, height: $180.2{\pm}5.6$ cm, body mass: $73.6{\pm}6.7$ kg, career: $10.6{\pm}0.9$ yrs). Three-dimensional motion analysis with 7 infrared cameras was performed with a sampling frequency as 200 Hz. Player's swing motion was divided into four events: starting motion (E1), backswing (E2), impact (E3), following (E4). For all upper joints, LSG showed greater angle differences between drop and smash motions than that of SG at E3 (p<.05). For all upper joints, greater angular velocities were found in SG than that of LSG. For both groups, significantly smaller angular velocities were found in drop motion than that of smash motion (p<.05). The greater sequential angular velocities (proximal to distal) were found in SG than LSG during smash motion. Based on our findings, performing the same motion between drop and smash would be related to enhance performance at badminton competition. It is expected that these results will be useful in developing a training program for enhancing performance of badminton athletes.
