A new field of e-sports gains the great popularity in Korea as well as abroad. AOS (aeon of strife) genre games are quickly gaining popularity with gamers from all over the world and the game companies hold game competitions. The e-sports broadcasting teams and webzines use a variety of statistical indicators. In this paper, as an AOS genre game, League of Legends game data is used for statistical analysis using the indicators to predict the outcome. We develop new indicators with the factor analysis to improve existing indicators. Also we consider discriminant function, neural network model, and SVM (support vector machine) for make winning forecasting models. As a result, the new position indicators reflect the nature of the role in the game and winning forecasting models show more than 95 percent accuracy.

The purpose of this study is to design a process for developing wearable sports helmet devices by utilizing IoT server technology, focusing on sports where helmet wear is essential at sports sites. This enables customized training of athletes by continuously accumulating personal biometric information during training, checking players' condition based on data, and informing them of injury prevention and dangerous situations. In addition, the wearable device that can be useful when the training place is likely to damage the physical health due to heat waves or extremes can provide a foundation for improving the performance. Since such technology can be applied not only to the sports field but also to the society such as the industrial field or the underprivileged, it can be expected to be expandable.

This study aimed to investigate the formation of the social perception of domestic maritime sports using text mining analysis of keywords and topics from domestic media coverage over the past 10 years related to representative maritime sports, including yachting, rowing, and canoeing. The results are as follows: First, term frequency (TF) and word cloud analyses identified the top keywords: "maritime," "competition," "experience," "tourism," "world," "yachting," "canoeing," "leisure," and "participation." Second, semantic network analysis revealed that yachting was correlated with terms like "maritime," "industry," "competition," "leisure," "tourism," "boat," "facilities," and "business"; rowing with terms like "competition" and "Chungju"; and canoeing with terms like "maritime," "competition," "experience," "leisure," and "tourism." Third, topic modeling analysis indicated that yachting, rowing, and canoeing are perceived as elite sports and maritime leisure sports. However, the perception of these sports has been demonstrated to have little impact on society, public opinion, and social transformation. In summary, when considering these results comprehensively, it can be concluded that yachting and canoeing have gradually shifted from being perceived as elite sports to essential elements of the maritime leisure industry. Contrariwise, rowing remains primarily associated with elite sports, and its popularization as a maritime leisure sport appears limited at this time.

The role of venture CEO and their intrinsic capabilities on organizational performance can be determined by the level of resource synchronization initiated by the focal managers. Despite the important role of venture CEOs, a systematic lack of in-depth theoretical and empirical studies on ruminating the relationship between the effects of a CEO's capabilities and organizational performance depending on the level of resource synchronization exist for the rationale of investigation. To supplement the limitations of previous studies, this research empirically analyzes the role of managers specifically synchronizing organizational resources that affect organizational performance in the professional sports industry. Based on the entrepreneurship theory and resource-based view (RBV), this research conceptualizes the roles of venture CEO and basketball head coach in the professional sports industry as very similar in terms of organizational structure and performance mechanism embedding entrepreneurial characteristics necessary for managing organizational resources. In this research, we hypothesized (1) organizational resource synchronization will mediate the positive relationship between the ability of professional basketball head coach and organizational performance and (2) the indirect effect of the professional basketball head coach's capabilities on organizational performance mediated by resource synchronization will be moderated by the capabilities of players. To test these hypotheses, we utilized the PROCESS macro model 58 with the empirical data of 9 seasons (2013~2014-2021~2022) of 30 National Basketball Association (NBA) and 10 Korean Basketball League (KBL) teams. The statistical results showed that (1) resource synchronization mediates the positive relationship between professional basketball head coach capabilities and organizational performance and (2) the capabilities of players moderated the indirect effects of the abilities of head coaches on team performance via resource synchronization. This paper contributes to both academic and practical domains of entrepreneurship by empirically testing the research model through objective professional sports data.

비디오 데이터 분석은 감시, 검색, 스포츠 경기 자동 요약 등 많은 분야에서 사용되는 기술이다. 그러나 감시 카메라나 스포츠 경기 비디오와 같이 사람의 영역이 저해상도인 환경에서는 포즈 추정, 모델과의 매칭이 어렵기 때문에 제스처 인식 연구는 많이 이루어지고 있지 못하다. 본 논문에서는 카메라가 Pan/Tilt/Zoom 동작을 하고 사람이 빠르게 움직이는 방송용 테니스 비디오에서, 사람을 추출하고, Curvature Scale Space를 기반으로 한 특징을 추출하여 학습된 포즈 모델과 매칭하는 방법과, 차원의 축소를 통해 일련의 포즈들을 학습된 제스처와 매칭하는 방법을 제안한다. 50개의 방송용 테니스 경기 비디오 장면에 대하여 서브 제스처 추출을 수행한 결과, 서브 포즈에 대하여 모델과 매칭이 잘 되고, 매칭이 되지 않는 포즈를 포함하는 시퀀스에 대해서도 강인한

스포츠 클라이밍에서 효율적인 등반을 위해서는 인공 암벽의 홀드 위치 및 형태에 따라 역학적으로 이득이 높은 자세를 취할 수 있도록 반복적인 훈련이 필요하다. 교육자는 초급 수준의 등반자를 교육하기 위해서 매번 직접 시범을 보여야 하는 불편함이 있다. 만약 등반자 혼자서도 자세를 배울 수 있는 사실적인 등반 애니메이션이 제공된다면, 효율적인 훈련이 가능할 것이다. 이에 본 논문에서는 게임 엔진의 역운동학 기능으로 제작 과정을 간소화하고 게임 콘솔용 깊이 카메라 기반의 모션 캡쳐 데이터를 분석 및 적용하여 올바른 등반 자세 교육을 위한 3D 캐릭터 애니메이션을 제작하는 방법을 제시한다. 향후 애니메이션이 제작되면 스포츠 클라이밍 교육 콘텐츠를 제작의 기초가 되어 기존 등반 교육 과정에서 제공하지 못했던 새로운 경험을 등반가들에게 제공할 것이다.

본 논문에서는 웹 문서의 분류 성능을 향상시키기 위해 웹 페이지에서의 자질선택과 그에 따른 웹 문서 분류 방법을 제안한다. 문서 분류에는 문서에 포함된 단어를 분류 자질로 사용하게 되며 이때 한 문서의 모든 단어를 분류 자질로 이용한다고 좋은 성능을 보인다고 보장할 수는 없다. 그러므로 문서에 필요한 단어만을 자동으로 추출하여 문서데이터의 자질을 축소하는 작업이 필요하다. 따라서 본 논문에서는 모집군 내의 자질벡터의 범위가 큰 것을 적은 수의 주요성분으로 감소시키기 위해 통계적 분석 기법중의 하나인 주성분분석 방법을 이용하여 자질감소와 그에 따른 문서분류의 성능 향상을 실험을 통하여 보인다. 야후 스포츠 뉴스 웹 페이지가 분류를 위해 사용되었으며, 분류기로는 Naive Bayesian 분류 방법을 사용하였다. 실험 결과를 통해 본 논문에서 제안한 뉴스 웹페이지 분류 방법이 스포츠 뉴스 데이터 군에서 만족할 만한 분류 정확도를 제공한다는 것을 알 수 있다.

This paper investigates different types of leadership found in foreign coaches in charge of the Korean national soccer team. To that end, news articles published during the tenure of those coaches were crawled for analysis. The analysis highlighted the following results. First, successful sports leaders showed their own specific types of leadership. Second, failed sports leaders showed specific types of leadership. The findings have the following implications. The leadership established based on the analysis results have practical implications in that they suggest the types of effectiveness leadership that are required of sports leaders in managing and leading athletes whilst generating tangible results and performance.
