청소년 태권도 선수들의 평가염려 완벽주의가 경쟁상태불안에 미치는 영향
김종탁 한국무예학회 2018 무예연구 Vol.12 No.1
The purpose of this study was to investigate the effects of evaluative concerns perfectionism on competitive state anxiety of adolescent Taekwondo players. In order to achieve these purposes, survey was conducted with 205 adolescent Taekwondo players in Gyeonggi and Chungcheong province areas. The following conclusions were made. The correlation between evaluative concerns perfectionism and competitive state anxiety showed a significant level between each dimensions The influence that evaluative concerns perfectionism have on cognitive state anxiety and somatic state anxiety are "anxiety about a mistake“, "a doubt about the performance" and "socially prescribed perfectionism". There are no factors that influence the state confidence. The results of this study suggest the importance of addressing the evaluative concerns perfectionism in dealing with competitive state anxiety. Based on the above results, the significance and limitations of this study and recommendations for further study were discussed. 이 연구는 청소년 태권도 선수들의 평가염려 완벽주의가 경쟁 상태불안에 미치는 영향력을 검증하는데 그 목적이 있었으며, 중, 고등학교 태권도 선수들 205명을 대상으로 경쟁 상태불안에 대한 평가염려 완벽주의의 영향력을 검증한 결과, 평가염려 완벽주의의 하위요인들과 경쟁 상태불안의 하위요인들 간에는 정적, 부적으로 유의한 관련성이 있는 것으로 나타났으며, 경쟁 상태불안의 하위요인인 인지적 상태불안과 신체적 상태불안에 가장 많은 영향을 미치는 요인은 실수에 대한 염려로 나타났으며, 다음으로 수행에 대한 의심과 사회적으로 부과된 완벽주의가 영향력이 있는 것으로 나타났고 상태자신감에 영향을 미치는 요인은 없는 것으로 나타났다. 이 연구의 결과들은 경쟁 상태불안의 대처에서 평가염려 완벽주의에 대해 다루는 것의 중요성을 시사하며, 인지적 상태불안과 신체적 상태불안과 같은 경쟁 상태불안 수준을 감소시키기 위해서는 실수에 대한 염려나 수행에 대한 의심 및 사회적으로 부과된 완벽주의 수준을 효율적으로 통제해야할 필요성이 있으며, 이에 평가염려 완벽주의 성향을 효율적으로 통제시킬 수 있는 훈련 프로그램의 개발이 필요할 것으로 사료된다.

Dynamic compression fracture behaviors together with damage mechanisms of materials subjected to a compressive load at a high strain rate were studied by using a Self-organizing map (SOM). The materials used for the analysis were Al5083, Rolled homogeneous armor (RHA) and tungsten heavy alloy (WHA). The deformation behavior and Acoustic emission (AE) signal were acquired through a Split Hopkinson pressure bar (SHPB)-AE coupled test. The self-organization map which is one of the artificial neural network technique was employed to classify the AE energy, amplitude, and peak frequency according to the characteristics of the signal. In addition, distributions of AE signals were represented in stress-strain curves. The correlation between AE characteristics and material damage mechanisms was investigated. Based on the results, it was found that cluster 1 with high AE energy, high amplitude and low frequency was the cluster of the AE signal generated near the yield point of the material. Cluster 3, which has the opposite tendency, was confirmed as a cluster of AE signals that occurred just before a fracture of the material. The change in the measured value can be seen depending on the strain rate and the material, but the overall tendency was similar.

This paper discusses major reform issues on the defense manpower management through the 6 White Papers since the Defense Reform Act was enacted in 2006, and proposes mid-term policies and issues on it. They need to be focused on effectively managing all kinds of defense manpower groups in ``total forces`` concept. And some of them are proposed to advance defense civilian and military personnel management systems, and others to develop the defense manpower structures.

The purpose of this research is to find relationships between safeguards' personality traits and stress coping behaviors. The findings then could provide data to adapt safeguards to their duties. For that, personality traits such as sociability, stability and stress coping behaviors and the effects were investigated. In addition, cognitive aspects which were known to influence stress coping behaviors were appraised. The findings of this research are as follows, First, regarding personality traits and stress coping behaviors, the unstable and unsocial group used the emotion-focused coping style more than the stable and social group. The two groups didn't show any significant differences in the problem-focused coping style. The A-type group used both the problem-focused style and the emotion-focused style more than the B-type group. The common characteristic of the unstable, the unsociable and the A-type groups was the heavy use of avoidance behaviors of the emotion-focused coping style. Second, In the correlation between the personal traits and the stress coping effects regarding adaptability, the stability influenced stress coping effects. Third, regarding the personality traits, the coping styles and the coping effects, A-type group showed high correlation with the sociability but not with the stability. The problem-focused coping style showed high correlation with the emotion-focused style. Fourth, the cognitive appraisal on the stress causes influenced the stress coping styles but not the stress coping effects. Fifth, the cognitive appraisal on the same stress causes didn't show any significant differences among the personality traits.
