다양한 객체 추적 기술들이 스포츠 분야에 활용이 되면서, 방송이나 경기력 분석에 많이 사용되고 있다. 이 연구에서는 2014년도 K리그 경기중 승패가 결정된 17경기를 동영상 경기 분석 프로그램으로 처리된 데이터를 활용하여 뛴 거리와 경기 승패와의 관련성에 대해서 통계적으로 분석한다. 뛴거리는 총 뛴거리, 점유시 뛴거리, 비점유시 뛴거리로 나누어 분석하고, 그 결과 비점유시 뛴거리의 차이가 경기의 승패에 영향을 준다는 것을 카이검정을 통해 확인하였다.

In this paper, we propose the measurement camera system of flight data of golfball for the application of screen golf contents. The existing flight data extraction system that applied on the screen golf content divided plate is dependent on it. in this paper, the camera system install in the ceiling that is able to look at passing golf ball. And left-handed and left-handed bats in the clear of the restrictions. Using high-speed CCD camera is shooting the ball flying. Acquired image is calculated from the coordinates. The location information of the calculated golf ball calculates a speed and a direction by using the physical formula, it applies the golf contents. After this system is useful sports type contents baseball, soccer, tennis.

The research for the regional identity including relationships with professional sport team was caused by local autonomy system and localism. This study was to verify structural relationships among regional identity, team identification and re-attend intention of professional soccer spectators. Data were collected from spectators of professional soccer game in 'D' metropolitan city. Using purposive sampling method, a total of 397 samples were used for analysis. The statistical techniques for data analysis were descriptive analysis, frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural equation modeling by SPSS 15.0 and AMOS 7 programs. The results of this study were that regional identity have a positive effects on team identification. Also, team identification have a positive effects on re-attend intention. Theoretical and practical implications and future research directions were provided.

Purpose: This study was performed to analyze the mechanism and type of knee injury during soccer game and to evaluate the functional recovery after treatment. Materials and Methods: From October 2002 to January 2005, 49 patients were treated surgically. Mean age was 28.8 (8-36) years old, mean follow-up duration was 14.9 (8-36) months. Injury was evaluated by physical examination, radiography, and arthroscopic finding. Clinical results were evaluated with Lysholm score and Tegner activity score. Results: According to classification of the ligament injury, the incidence of single ACL injury was the most frequent and 27 cases. Injuries took place, in 2nd half of the games, and in the winter. Among the mechanism of injury, turn & twisting was 20 cases and the most frequent. The preoperative Lysholm score, Tegner activity score were 45, 2 and those of last follow-up were 87.6, 6, respectively. Conclusion: The recovery of Lysholm and Tegner activity score were good, but the sports activity was clearly decreased alter injury. It was suggested that appropriate physical & psychological rehabilitation and education were inevitable.

This paper introduces the HD 3DTV camera and 3DTV receiver that are compatible with the ATSC HDTV broadcasting system. The developed 3DTV camera is based on stereoscopic techniques, and it has control function to control both left and right zoom lens simultaneously and to control the vergence. Moreover, in order to control the vergence manually and to eliminate the synchronization problem of the both images, the 3DTV camera has the 3DTV video multiplexing function to combine the left and right images into the single image. The developed 3DTV signal, and it has the various analog/digital interfaces. The performance of the developed system is confirmed by shooting the selected soccer game in 2002 FIFA KOREA/JAPANTM World Cup and by broadcasting the match. The HD 3DTV camera and receiver will be applied to the 3DTV industries such as 3D movie, 3D game, 3D image processing, 3DTV broadcasting system, and so on.

Purpose: To investigate the risk exposure, risk of injury, and injury pattern of football players in seasonal variation. We purposed to expect the injury and its' prevention. Material and Methods: The professional football club(45 players) in Seoul were followed prospectively throughout 2005, January to 2005, December. Injury pattern and incidence were recorded. Results: Total 157 injuries were recorded. Major injuries which could not attend to game and training were 87 cases. Most severe month was June about 16 injuries(18.4%). And, the competitive season injuries were 46(52.9%) in March, April, August and September. Especially, ankle sprain and contusion injuries were common cause of absence in game. And, thigh muscle group injuries had a high risk of reinjury, because of treat insufficiently. Conclusions: We enhance the ability of the soccer team by prevention and education for injuries, especially in season.

The rapid growth and dissemination of touch-based mobile devices such as smart phones and tablet PCs, gives numerous benefits to people using a variety of multimedia contents. Due to its portability, it enables users to watch a soccer game, search video from YouTube, and sometimes tag on contents on the road. However, the limited screen size of mobile devices and touch-based character input methods based on this, are still major problems of searching and tagging multimedia contents. In this paper, we propose WalkieTagging, which provides a much more intuitive way than that of previous one. Just like any other previous video tagging services, WalkieTagging, as a voice-based annotation service, supports inserting detailed annotation data including start time, duration, tags, with little effort of users. To evaluate our methods, we developed the Android-based WalkieTagging application and performed user study via a two-week. Through our experiments by a total of 46 people, we observed that experiment participator think our system is more convenient and useful than that of touch-based one. Consequently, we found out that voice-based annotation methods can provide users with much convenience and satisfaction than that of touch-based methods in the mobile environments.

In this paper, we present the experimentation and demonstration results of Korea-Japan high-speed satellite ATM network using Ka-band Koreasat-3. This experimentation consists of two items - TCP/IP and MPEG-2 video/audio transmission over 155Mbps ATM based satellite network. The goals of this experimentation are to measure TCP performance when the only standard mechanisms approved by IETF in order to improve TCP performance in LFN(long fat network) are used and to derive the effects of quality for the high definition video stream when MPEG-2 TS is transmitted through 155Mbps satellite ATM link. With on the results of the experiments, we demonstrated the applications suitable to the high-speed satellite ATM network. The first TCP/IP and MPEG-2 transmission experiments were done at the rate of 155Mbps using Ka-band KOREASAT-3 between Korea and Japan, and its results will be demonstrated with the ATM-based 3D-HDV(3 dimensional High definition video) and HDTV during 2002 Korea-Japan World Cup Soccer Game.

An anterior dislocation of the elbow without a fracture of the olecranon is an extremely rare injury. This paper reports a 36-year-old male who stumbled and fell on his outstretched hand during a soccer game. The anteroposterior and lateral radiographs indicated a simple anterior dislocation of the elbow, which was reduced using a closed method. The elbow joint was stable in the range of motion, but the sensation of the two ulnar digits was still reduced. MRI was useful for the identification of the pathoanatomy. At the follow-up examination three months after the initial trauma, the hypesthesia has fully recovered and the patient regained the full range of the elbow and forearm motion without pain and instability. After 18 months, the patient had a normal elbow function, and could play various sports. If an anterior elbow dislocation is detected early, a closed reduction with careful pathoanatomical considerations would be successful.

This paper studies how 2006 German World cup game gave World cup-aftermath to Korean people living in Korea. In order to study, the time exposure to soccer matches like Korea vs. Togo, Korea vs. Swiss, and Korea vs. France respectively was analyzed. Additionally, in order to evaluate media effect, respondents' demographics, and preference toward sports were controlled using a hierarchial regression method. Based on the results, exposure to radio was statistically significant to Koreans' indirect aftermath.
