The purpose of this study is to investigate on sports injures and performance in combat sports events. For the purpose, in the study 239 subject(boxing 50, taekwundo 54, wrestling 41, fencing 54, judo 40) completed the questionnaire for sports injures and performance in combat sports events. It was divided sports player's performance into high performance elite level and low performance elite level. To assess of the distribution in high performance elite level and low performance elite level player's injures pattern, it was used cross table and percentile scores by SPSS version 11.0 for Windows. The result was follow that: There was different pattern in sports injures by combat sports event. And there was different pattern in sports performance in high performance elite leve and low performance elite level players.

The purpose of this study was to empirically examine the relationships of goal orientation self-efficacy and performance level on activity level of boxing players. From the analysis of this study, the following conclusions were obtained: 1. There was a partial difference in the goal orientation according to the activity level of boxing player. That is say, middle school boxing player was higher the perceived level for tack involvment goal orientation than the others university boxing player was lower. But the self involvment goal orientation according to the activity level of boxing player did not show the difference. 2. There was a partial difference in the self-efficacy according to the activity level of boxing player, did not show the difference. 3. The goal orientation of boxing player had a partial influence on the self-dfficacy. The tack involvment goal orientation of boxing player affected positively on the self-efficacy, while self involvment goal orientation did not have any influence on the self-efficacy. 4. There was a partial casual relation in the goal orientation self-efficacy, performance level of boxing player. The tack involvment goal orientation boxing player affected positively on the performance level by the self-efficacy, the tack involvment goal orientation and self-efficacy affected positively, directly on the performance level.

국내의 대부분의 절연화는 14,000~30,000 V 의 내전압의 특성을 가진다. 기존에 보고된 절연화는 절연 효과를 극대화하기 위해 아웃솔(바닥창, 고무창)의 두께를 두껍게 제조했다. 하지만 두께가 두꺼워지는 만큼 신발의 무게도 함께 증가하기 때문에 작업자의 피로도는 상승하게 된다. 이를 해결하기 위해는 기존 절연화의 아웃솔보다 얇은 두께에서도 절연 성능이 확보되는 조성물 개발이 필요하다. 본 연구에서는 아세틸렌 블랙의 함량에 따른 전기적 특성을 비교 평가하였다. 이를 통해 기존보다 얇은 두께에서도 우수한 전기 절연성을 지닌 절연화를 구해보고자 한다.
