Purpose: The purpose of this study is to identify bilateral differences of physeal closure of the lateral compartment of the elbow in osteochondritis dissecans (OCD) and related factors with premature physeal closure. Methods: Initial radiographs of the bilateral elbows in 40 baseball players with OCD (group I) were reviewed for the status of physeal closure of the lateral compartment; capitellum, radial head, lateral epicondyle. Forty baseball players with medial epicondylar apophysitis (group II) were enrolled as a control. Relative status of physeal closure of dominant elbow was defined as early, same, and delayed. Bilateral differences of the status of physeal closure were analyzed between groups, and according to the radiographic stages, extent of the lesions and demographic factors in group I. Results: Significant early physeal closures of dominant elbows were identified in group I in capitellum (group I, 55%; group II, 3%), radial head (group I, 53%; group II, 3%), and lateral epicondyle (group I 37%; group II, 5%). In group I, advanced stage and extended lesion showed early lateral compartment physeal closure especially in capitellum and radial head, and players with longer career length and limitation of motion showed early closure. Conclusion: Over the half of the adolescent baseball players with OCD demonstrated early radiocapitellar physeal closures of dominant elbow in initial presentation. Because premature physeal closure contributes to the development of arthritis without appropriate radiocapitellar remodeling, early detection of OCD is essential for prevention of arthritis and successful conservative management.

This study is intended to suggest ways to improve the quality of the service of subtitles provided for the convenience of viewing for deaf people on e-sports broadcast content and game streamer content. Generally, subtitling files of broadcast content are manually written on air by stenographers, so a delay of 3 to 5 seconds is inevitable compared to the original content. Therefore, the present study proposed the formation of an automatic synchronization calibration system using speech recognition technology. In addition, a content application experiment using this system was conducted, and the final result confirmed that the time of synchronization error of subtitling data could be reduced to less than 1 second.

The purpose of this study is to investigate the reality of verbal violence by leaders in the sports field to inform the seriousness of the damage suffered by athletes and to prepare a starting point for social interest and intervention. To this end, in-depth interviews were conducted with seven players who experienced verbal violence by the leader, and a qualitative case study method was adopted for a multifaceted analysis of verbal violence. As a result, 14 detailed areas and 5 categories were derived. Taken together, the verbal violence of the leader experienced by the players occurred in ambiguous, repetitive, and closed situations and had a structure of passive response. Since verbal violence affects the victim's personal and social problems without leaving evidence against trauma or perpetrators, a close understanding of the atmosphere and environment of the site is considered essential for preparing fundamental measures. Based on the results of these case studies, attention and intervention should be urged through understanding of secretly conducted verbal violence, and close policies should be prepared to supplement the blind spots of verbal violence.

This study that had been conducted two months by a research team of Pusan National University at the request of Korea Manwha Contents Agency in Dec. 2013 is about the statistical analysis on 'Korean Webtoon DB and its Flow Report' which resulted from the complete survey of Korean webtoons which had been published with payment in official media from early 2000 to 2013. Webtoon which means the cartoons published on web has become a typical type of Korean cartoons and has developed into a main industry since 2000s when traditional published cartoons had declined and social environments had changed. Today, it represents cultural contents in Korea. This study collected the webtoons officially published in media with payment, among Korean webtoons having been published from the early 2000s to Jan. Based on the collected data, it analyzed the general characteristics of webtoons, including cartoonists, the number of cartoons, distribution chart of each media, genre, and publication cycle. According to the data analysis and statistics, a great deal of Korean webtoons are still published in main portal websites, but their platform is being diversified and a webtoon's publication cycle tends to be shortened. In terms of genre, traditional popular genres, such as drama, comic, fantasy, and action, are still popular, and the genres of history, sports, and food are on the rise along with a social trend. Regarding webtoon application, such events as relay webtoon and brand webtoon, and a new type of webtoon featuring PPL commercialism appear. Such phenomena can realize the common profits of cartoonists, media, and ordering bodies, and are various trials to test the possibility of webtoons. In addition, what needs to pay attention on in the expansion of webtoons is increasing webtoons for adults. The study subjects are the webtoons published with payment, excluding free webtoons. However, this study failed to collect the webtoons published on the online websites already closed, and the lost information on cartoonists and their lost webtoons, and it is necessary to conduct a complete survey on all webtoons including free ones. Despite the limitations, this study is meaningful in the points that it categorized and analyzed Korean webtoons accoridng to official media, webtoons, cartoonists, and genres and that it provided a fundamental material to understand the current conditions of webtoons. It is expected that this study will be able to contribute to activating more research on webtoons and producing more supplementary data which will be used for the Korean cartoon industry and academia.
