  • Rupture of the pectoralis major muscle may occur in youngers or athletes associated with extreme sports, especially during the weight training. It is uncommon, but the incidence is increased by the recent growth of athletic population, According to the drift, variable methods of operative treatment for the functional and cosmetic recovery are introduced. We report a case of pectoralis major muscle rupture which was successfully repaired using transosseous repair and suture anchors five months after the initial injury during the bench-pressing.

  • Avulsion of the hamstring tendon from the ischial tuberosity is common in many sports, especially with younger athletes. The injury results from a sudden forceful flexion of the hip joint when the knee is extended and the hamstring muscles powerfully contracted. Early diagnosis and surgical repair with reattachment of avulsed muscles to the ischial tuberosity restore function and correct deformity. But, a delay in the diagnosis and treatment leads to a poor result functionally and clinically. Complication, such as heterotopic ossification and failure of the fixation, etc., were reported following a surgical procedure for this injury. However, sciatic nerve injury has not been reported in the literature. We report our experience of a sciatic nerve palsy after surgery that was performed three months after that the initial injury.

  • The purpose of this paper is to analyze social phenomena and perceptions by collecting and analyzing data on public opinion, views and trends related to special case of military service in the sports community through Big KINDS operated by the Korea Press Promotion Foundation. To this end, the related keywords were derived and visualized by implementing a LDA(latent dirichlet allocation) technique to derive problems found in social phenomena based on big data analysis. The topics derived include "re-lighting special case on military service," " military service corruption controversy," "special case of military service for athletes," "alternative military service system for artists " and "parliamentary inspection of the administration" This could be used as a basic data for identifying accurate information on social controversies related to special case of military service in the sports community and drawing up practical measures that are considered in line with the principle of just and equal burden.

  • The purpose of this study was to analyze correlation between kinematic variables and ground slope perception ability during golf putting. 16 collegiate golfers were participated. To collect and analyze the kinematic data of putter head, SAMPutt lab was used(70 Hz). It was performed Pearson's correlation analysis using SPSS. The level of significance was at .05. As a results, right was correlated with backswing in flat. Toe-up was correlated with follow-through and left was correlated with aim, backswing, impact, follow-through, and loft in slice 1°. Toe-down was correlated with aim, backswing, impact in slice 2°. Toe-up was correlated with follow-through in hook 2°. In conclusion, it is important to improve the putting stroke through repetitive ground slope perception training.

  • The purpose of this study was to analyze relationship between biomechancal factors and diver's distance during golf driver swing. Fifteen professional golfers were participated in as subject. Eight motion capture cameras(250 Hz), 2 force plates(1000 Hz), and Trackman were used to collect kinematic and kinetic datas. It was performed Pearson's correlation analysis using SPSS 24.0. The level of significance was at .05. Ball speed, club head speed, X-Factor, and ground reaction force were correlated on driving distance, However, smash factor and knee moment were not correlated on driving distnace. Ball speed, club head speed, X-Factor, and ground reaction force were effected to driving distance, but smash factor and knee moment were not effected to driving distance.

  • Professional baseball is one of the spectator sports that has been loved for a long time by the citizens as a recreational activity since its establishment in 1982, and has been playing pivotal role as a national sport. However, there has been decline in the number of audiences since 2019. Hence, this research paper aimed to provide strategic direction for planning and improvement of professional baseball stadiums by applying the concept of servicescape. In this research, five key factors of servicescape that affects players performance and the level of immersion of spectators were derived through literature review, and based on these key factors, case study analysis were carried out for 51 domestic and foreign baseball stadiums while focusing on the factors derived. Domestic baseball stadiums highly concentrate on spectatorship without effectively responding to change in spectators demand and its effective use of space rather than baseball games. As in foreign cases, it is critical to modify mangement process and planning direction, and improve policies while perceiving baseball stadium as recreational and cultural space.

  • A numerical analysis is carried out in order to obtain aerodynamic data of the ski jump. The body modelling of Korean people is used in the numerical simulation and the result is validated by comparing it with the wind tunnel experiment. A flying posture, which provides the maximum lift-to-drag ratio, is found by analyzing the aerodynamic coefficients of various flight conditions. The result of the present study can be applied to fixing the postures of Korean ski players and is expected to advance the national sports science.

  • 최근 딥러닝(Deep-learning)을 활용한 기상 예측, 심리 예측, 교통상황 예측 등 다양한 분야에 걸쳐 여러 모델의 인공신경망이 활용되고 있다. 본 논문에서는 여러 분야 중 스포츠라는 분야에 접근했으며, 딥러닝 모델을 통해 승부를 예측하는 실험을 진행하였다. 야구의 승부는 선수의 능력치, 기상의 변화, 험/어웨이 여부, 교체 여부 등 가늠할 수 없이 수많은 데이터들에 의존하고 있다. 그러나 본 논문에서는 이러한 수많은 데이터 중 경기 외적인 데이터를 제외한 데이터를 활용하여 그 다음 경기의 승부를 예측할 수 있을 지를 연구한다. 날짜 별 경기들이 훈련데이터가 되고 목표는 이전 경기들의 영향으로 예측된 다음 경기의 승/패를 예측한다. 즉 순차적인 데이터의 활용에 적합한 모델, Recurrent Neural-Network을 이용하였다. 이를 위하여 KBreport에서 데이터를 수집하였고, 수집된 데이터를 훈련 데이터 세트로 만들어 Recurrent Neural Network를 통해 훈련시켜 다음 경기의 승패를 예측하였다.

  • 실생활에서 많이 행해지고있는 배드민턴, 테니스 등의 운동에서 전문가에 의한 자세교정, 원격 코칭에 대한 필요성이 대두된다. 스스로 운동을 재대로 하고 있는지 확인함과 유명 선수의 운동 자세를 따라하고 싶은 욕구를 해소할 수 있는 소프트웨어 솔루션을 개발하는데 의의가 있다. 또한 스마트폰과의 연동으로 젊은 층의 수요를 흡수한다.
