The purpose of this study was to investigate the construct of Korean Version of Mental Toughness through Open-ended Questionnaire for soccer Players and coach. Data collection was inductively analyzed by distributing open questionnaires to 100 soccer players belonging to the Korean Football Association and 100 soccer coaches who participated in the training for obtaining a soccer coach's license. The resulting results are as follows. First, as a result of the inductive content analysis of korean version soccer players mental toughness, 11 factors were derived in the detailed area and 6 factors in the general area. Secondly, in the results on the mental toughness of Korean version soccer players according to soccer players and coaches, both players and coaches were found to be the highest factor, kkangdagu. I hope that the results of this study will be used as basic data for efforts to reduce the improving performance for soccer players and coaches.

축구경기는 세계적으로 널리 알려진 스포츠이다. 특히, 한국과 일본은 2002년 월드컵을 개최하는 나라이다. 이와 같은 배경에서, 우리는 퍼지 논리를 이용하여 축구 선수들의 기본적인 동작(Motion)을 인식하는 알고리즘을 제안한다. 여기서 기본 동작이란, 걷기, 뛰기, 드리블하기, 서있기 등으로 정의한다. 만약 우리가 축구경기 장면 비디오를 통해 동작 인식을 필요로 한다면, 특징 패턴은 축구선수들의 양다리 각과 한 축구선수와 공과의 거리가 중요 요소가 될 것이다. 이 논문은 축구 선수 및 공의 추적(Tracking)을 통해 전처리된 데이터를 얻을 수 있다고 가정한다. 실험결과를 통해 축구선수 뿐만 아니라 스포츠 경기에서 선수들의 기본 동작 인식에 퍼지 논리를 적용할 수 있음을 알 수 있었다.

얼굴 인식 성능을 저해하는 환경으로 인한 축구 비디오에서의 낮은 선수 인식률과 제한된 해공간의 문제점을 해결하는 차원에서 본 논문에서는 다음과 같은 특징을 갖는 얼굴 인식 기반의 축구선수 인식 방법론을 제안한다: 1) 조명 변화에 민감하지 않은 얼굴 표현 방법인 ULBP를 사용하여 얼굴 인식 성능을 향상시킨다; 2) 얼굴 인식 성능을 저해하는 다양한 환경에서도 이미 강인한 성능이 검증된 SRC를 선수 식별 과정에 적용함으로써 안정적이고 높은 선수 식별 성능을 보장한다; 3) 클로즈업 샷뿐만 아니라 미디엄 샷의 정면, 준정면, 측면 얼굴 이미지를 대상으로 선수 식별의 해공간을 확장한다; 4) SRC의 점증적 갱신 학습 능력으로 축구 선수 얼굴 데이터베이스의 변화에도 능동적으로 적응한다. 실제 2010년 남아프리카 공화국 월드컵의 스페인 경기를 대상으로 제안된 방법론의 성능을 실험적으로 검증한다.

This study was conducted to find out whether excellent and non-excellent players could be distinguished by the achievement goal orientation(task-orientation, ego-orientation) test and the self-management(physical, interpersonal, training, mental management) test targeting youth soccer players. The subject of this study were 299 players(144 middle school students, 155 high school students) including 131 representative players by age and 168 general players who registered with the Korea Football Association. The questionnaires for data collection include the Task & Ego Orientation in Sport Questionnaire(TEOSQ) developed by Duda and Nicholls(1989) and the athlete self-management questionnaire(ASMQ) developed by Heo Jeong-hoon(2003) was used. For data analysis, frequency analysis, factor analysis, reliability analysis, and discriminant analysis were performed using SPSS 23 version. As a result of analyzing the data, task orientation and ego orientation, which are sub-factors of achievement goal orientation, were both confirmed as tests that did not discriminate between excellent and non-excellent players. On the other hand, the self-management test was confirmed as a test that can discriminate between excellent and non-excellent players in body management, training management, and mental management excluding interpersonal management among the sub-factors of self-managemnet. In particular, among self-management, mental management was identified as the most important factor in discriminating between excellent and non-excellent athletes.

The purpose of this study was to propose an effective field test for assessing the cardiovascular endurance of soccer players by comparing the shuttle run test and the Yo-Yo intermittent recovery test (Yo-Yo test), which are representative of the aerobic exercise performance test, with the VO2max and other sprint tests. The shuttle run test requires the subject to run continuously without a break interval, while the Yo-Yo test has a break interval, so that they run with the recovery period. Therefore, the Yo-Yo test can be used as an effective field test for evaluating the cardiopulmonary function considering the characteristics of the soccer players of intermittent training.

이 연구의 목적은 발목관절의 발등굽힘 가동범위에 따라 동적 균형능력을 평가하는 Y-Balance Test와의 관계를 규명하고자 하였다. 이 연구 결과 HADR군에서 PLRD(P<.05)와 CS(P<.01)에서 유의한 차이가 나타났으며, 발목관절 발등 굽힘의 가동범위와 뒤안쪽 도달거리(PMRD), 뒤가쪽 도달거리(PLRD) 및 종합점수(CS)만 중등도의 유의한 상관관계가 나타났다. 따라서 발목관절 발등굽힘의 감소는 균형능력 능력을 감소와 관련이 있으며 축구선수의 손상의 예방하기 위해서는 정기적인 발목 관절가동범위를 평가가 필요한 것으로 생각된다.

This study aimed to examine the evolution of exercise performance and medical assessments in U-12 youth football players. Participants were recruited from an youth football players (YFG, n=15; $11.2{\pm}0.9yrs$) and normal youth (CON, n=15; $11.5{\pm}0.6yrs$). Both groups were tested for exercise performance (health related physical fitness, skill related physical fitness, functional movement screen; FMS and Y-balance) and medical assessments (lower extremity alignment, range of motion; ROM and manual muscle test; MMT). YFG showed a positive effects on pacer in health related physical fitness, 50-m run and Single-leg standing with eyes closed in skill related physical fitness, active straight leg raise and rotary stability in FMS, non-dominant composite score in Y-balance, respectively compared to CON. However, YFG showed a negative effects on Q-angle of dominant and non-dominant in lower extremity alignment, dorsiflexion of non-dominant, plantarflexion of dominant and non-dominan in ROM, hip extension and abduction, knee flexion and extension of dominant, knee flexion and extension of non-dominant in MMT, respectively compared to CON. These results indicated that U-12 youth football players have shown excellent exercise performance, but medical assessments has proved negative effects.

The purpose of this study is to examine difference in knowledge level, attitude and performance competence on CPR (Cardiopulmonary Resuscitation) in football players. For this, questionnaire survey was carried out from October 5, 2011 to October 19 targeting 234 football players of high schools and universities where are located in Seoul, Gyeonggi, and Gangwon-do Province. The collected data was carried out frequency, t-test ANOVA, and correlation analysis by using SPSS/PC 19.0 for Windows. All the statistical analyses were set for significance level in p<.05. The results are as follows. Knowledge level, attitude and performance competence on CPR according to football players' general characteristics were indicated to have influence upon gender, academic background, and the appearance of educational experience in CPR. It was indicated that there is difference between CPR-related characteristics, and knowledge level, attitude & performance competence. Also, it was indicated that there is correlation among knowledge level, attitude and performance competence on CPR in football players. Based on these results, it accurately grasps experience and knowledge level on CPR in football players, thereby making a place available for having a game with security, resulting in being considered to possibly make the better sports.
