  • 파랑 중 선수파의 영향을 줄이기 위해 도입된 Axe Bow선형은 파랑 중 항해 시 선수부에 과도한 Spray현상이 발생한다. 이를 억제하고자 선수 부가물이 도입되었으나, 수치해석적 연구가 필요할 것으로 판단하였다. 선수 부가물은 Spray rail에서 착안하였으며, 구현이 쉽고 설계 파라미터를 제시 할 수 있는 Barge형상으로 적용하였다. 본 연구에서는 선수 부가물의 길이 변화에 따른 Axe Bow 선형의 Spray 억제를 수치해석적으로 고찰하였다.

  • 한국과 미국의 사이클 선수들이 선호하는 사이클복에 대하여 조사하였으며 착용실태 파악을 위한 설문조사는 1997년 8월-10월 사이에 한국과 미국에서 동시에 실시하였고 총 145명 (한국인=79명, 미국인 =66명)의 설문결과가 데이터 분석에 이용되었다 설문내용은 인적사항 사이클복에 대한인식 및 계절에 따라 선호하는 스타일 등에 대해 35문항으로 구성되어 있으며 질문형식은 그림형과 서술형으로 나누어 작성하였다. 데이터는 빈도와 백분율로 비교하였고 {{{{ chi ^2 }} 와 Fisher's exact 방법을 이용하여 그 결과를 고찰하였다. 한국인 사이클 선수들의 Rohrer 지수는 한국 표준 체위조사의 같은 나이 집단의 수치와 거의 차이가 없으며미국인 남자 사이클 선수는 같은 나이 집단의 미국 군인들을 위한 체위조사 결과보다 낮은 수치를 나타냈다. 한국의 여자 사이클 선수들 중 79.6%가 사이클복이 시합이나 훈련중 기록향상에 영향을 미친다고 응답하였다. 대부분의 미국인 사ㅣ클 선수들은 그들이 착용한 사이클복에 만족하고 있으며 상하가 분리된 스타일을 선호하였다, 한국과 미국의 사이클 선수들은 jersey 의 경우 round neckline에 stand collar가 있는 스타일을 좋아하며 jersey 와 shorts 모두 몸에 꼭 맞는 스타일을 선호하였다.

  • 2012년 런던 올림픽의 막이 올랐다. 4년동안 땀과 눈물로 올림픽을 준비했던 선수들의 모습들은 모두 감동 그 자체이다. 올림픽이라는 세계 최고를 향한 승부에서 승리하기 위하여 선수들은 자신의 젊음과 인생을 걸고 매일매일 고된 훈련을 소화했을 것이다. 그런데, 올림픽의 주인공은 선수들만이 아니다. 올림픽에서 자신의 기량을 뽐내며 겨루고 있는 또 다른 주인공은 바로 선수들이 입고 있거나 사용하고 있는 운동복과 운동장비에 숨어 있는 첨단 과학이다. 첨단 기술 때문에 메달의 색깔이 바뀐다고 할 정도로 첨단 기술이 적용된 의류나 장비들은 선수들에게 있어서 훈련에 버금갈 정도로 중요한 요소이다.

  • The present study was conducted for analyzing changes in physique of at menarche of athletic and non-athletes. The maximum growth age of height and weight during menarche was not different between non-athletes and the athletes. Second, among non-athletes, those who had menarche late were taller and heavier than those who did early, and among the athletes, those who had menarche late were taller but lighter. The development rate of height was higher and the development duration was longer in the athletes than in the non-athletes. The development rate of weight was similar between the non-athletes and the athletes, but the maximum rate was higher in the athletes.

  • Recently, in the field of sports, the use of data in conducting games, planning seasons, and operating teams has increased significantly. Also, in order to develop better players, it has become necessary to use data to accurately analyze their performance. Therefore, in this study, various data about rookie players was collected and pre-processed in order to analyze and visualize their performance. Additionally, an analysis was conducted to determine at least how many opportunities should be given to foster rookie players. Then, a data analysis method was presented for nurturing athletes by using data in the field of sports. It is expected that this study will contribute to fostering rookie players by utilizing data.

  • This paper proposes a method of player event retrieval using combination of two functions: detection of player name in speech information and detection of sound event from audio information in golf videos. The system consists of indexing module and retrieval module. At the indexing time audio segmentation and noise reduction are applied to audio stream demultiplexed from the golf videos. The noise-reduced speech is then fed into speech recognizer, which outputs spoken descriptors. The player name and sound event are indexed by the spoken descriptors. At search time, text query is converted into phoneme sequences. The lists of each query term are retrieved through a description matcher to identify full and partial phrase hits. For the retrieval of the player name, this paper compares the results of word-based, phoneme-based, and hybrid approach.

  • The purpose of this paper is to identify whether the national baseball squad made up of the best players may get the outstanding results in the international competitions or not. Using Data Envelopment Analysis, the relative efficiency of players in Korean Baseball Organization is estimated as performance measure, and compared with the efficiency scores of national squad members. The paper focuses on the proper choice of DEA model in a baseball setting, thereby selecting the BCC model with non-discretionary variable. Two input variables(plate appearances and stolen bases to enforce) and three output variables(runs, on-base plus slugging and stolen base percentage) are used to evaluate the efficiency of the baseball players. Results showed that 22 players among 97 players were classified as efficient and 8 players among 12 national squad members were as efficient. These findings indicate a potential for DEA to be a major part of the analytical approaches in evaluating the relative efficiency of players.

  • This study aimed to quantify the attitude toward doping among handball players and to identify the influence of players' demographic information, knowledge of doping, education of anti-doping on the attitudes toward doping. 385 elite handball players (193 adolescent players, 165 adult players) were participated in this study and filled in the questionnaire about demographic information, knowledge of doping, education of anti-doping and Performance Enhancement Attitude Scale (PEAS). Collected data were analyzed by Stepwise multiple linear regression. Adult players were more generous about doping than adolescents, and, adolescent players' attitudes toward doping were influenced by their gender and age. In adults, attitudes toward doping were related with only the gender. These results would be useful information to develop the effective anti-doping strategy for handball play.
