This study considered the performing arts culture with a focus on Palgwanhoe Ceremony and various stunt-songs and dance (Baekhee-Gamoo) from the Goryeo period as well as examined the characteristics of performing arts' costume for Baekhee-Gamoo shown in Palgwanhoe Ceremony. The Baekhee-Gamoo shown in the Palgwanhoe Ceremony included acrobatics, traditions from comic dramas, puppet shows, mask plays, and four musical troupe flowers of youth in the Silla Dynasty, who excelled in beauty, bravery and the military arts (Sasun-Akboo). These were performed on a wagon ship with dragon, phoenix, and elephant animal masks (Yong-Bong-Sang-Mageosun). The characteristics of performing arts' costume for each performing arts are as follows. First, the general costume of the time was used for performing arts' costume. There were no special costumes for performing arts and it was just transformed or added for the efficiency of acrobatics. Second, the reality was improved by focusing on the historical research on costume suitable for characters and background of events in the performing arts to clearly deliver the purpose of the ceremony and quickly arouse audience's curiosity towards the performing arts' costume for the tradition of comic dramas and puppet shos in the Palgwanhoe Ceremony. Third, magical powers and symbolism were expressed through masks and performing arts' costumes. Palgwanhoe Ceremony aimed for magical powers that could protect weak human beings from threats and repel everything unfair while also symbolically showing the deified being through the performing arts' costume.

Burn-in is a widely used method to improve the quality of products or systems after they have been produced. In this paper, the problem of determining optimal burn-in time for a system which performs given mission is considered. It is assumed that the given mission time is not a fixed constant but a random variable which follows an exponential distribution. Assuming that the underlying lifetime distribution of a system has an eventually increasing failure rate function, an upper bound for the optimal burn-in time which maximizes the probability of performing given mission is derived. The obtained result is also applied to an illustrative example.

The purpose of this study was to analyze the comparisons of the kinematical variables when performing Yoko Ukemi(side breakfall) by three Stage in Judo. The subjects were four male judokas who were trainees Y. I. University Squad members and the Yoko Ukemi were filmed by two S-VHS 16mm video cameras(60fields/sec.). The selected times were subject to KWON 3D analysis program and kinematical analysis to compare variables of three Yoko Ukemi. Temporal variables(total time-required : TK, TR by each phase), the body part touched order on the mat and COG variables were computed through video analysis while performing right Yoko Ukemi by three stage. From the data analysis and discussion, the following conclusions were drawn : 1. Temporal variables : total time-required(TR) when performing Yoko Ukemi(side breakfall) by each stage, the first stage(full squat posture: FP : 1.11sec.) showed the shortest time, the next was 3rd(Shizenhontai, straight natural posture: NP : 1.41sec.), and 2nd(Jigohontai, straight defensive posture, DP : 1.42sec.), respectively- 2. TR when performing Yoko Ukemi(side breakfall) by each stage, and phase : the first phase(take of phase, average 0.68sec.) showed the longest time, next was the third phase(ukemi phase, 0.39sec.), and the second phase(air phase, 0.23sec.), respectively. 3. When performing yore Ukemi the body part touched order and TR on the mat : hip(0.94sec.) showed the shortest time, the next was elbow hand(0.97sec.), back(0.98sec.), and shoulder(1.04sec.) order. The hip part touched on the mat the first, but slap the mat in order to alleviate the shock try hand palm and forearm before receiving impact (difference 0.03sec,) 4. Vertical COG variables in each event by each stage : e1(ready position, average 78.33cm) moved the highest, the next was e2(jumping position, 70.14cm), e3(transition position, average 64.00cm), e4(landing position, average 35.99cm), and e5(ukemi position, average 18.32cm) order, gradual decrease respectively. And the difference of COG were showed in initial by each stage, because position fo Yoko Ukemi was difference by each stage in preparation position, but in accordance with executing of Ukemi phase that difference of COG was by decreasing, almost equal displacement in e4(landing) and e5(Ukemi)position finally.

Purpose: The purpose of this study was to investigate the muscle contraction onset time characteristics of the gluteus maximus, semitendinosus, and biceps femoris muscles at different knee flexion angles in individuals with shortened or over-lengthened hamstrings performing prone hip extension. Methods: Twenty-six participants were divided into a hamstring shortened group (n = 12) and hamstring lengthened group (n = 14). Wireless surface electromyography was used to verify the muscle onset time of the gluteus maximus, semitendinosus, and biceps femoris when performing prone hip extension at different knee flexion angles. Results: There were significant differences in the muscle onset times of the semitendinosus and biceps femoris between the hamstring shortened group and hamstring lengthened group (p < 0.05). In addition, there was a significant difference in the muscle contraction onset times among of the gluteus maximus, semitendinosus, and biceps femoris muscles when performing prone hip extension at a knee flexion of 90° in the hamstring shortened group (p < 0.05) and a knee flexion angle of 0° in the hamstring lengthened group (p < 0.05). Conclusion: In all groups, there was no effect on the onset time of the gluteus maximus muscle according based on the knee angle. In addition, the knee flexion angles affected the onset time of the muscle contraction of the gluteus maximus muscle in the hamstring shortened group and hamstring lengthened group with an abnormal length of the hamstring muscle.

The purpose of this study was to analyze the kinetical variables of the lower extremity joints when performing uchimata(inner thigh reaping throw) by uke(receiver)'s two posture(shizenhon tai), jigohon tai), by voluntary resistance level(VRL) in judo. The subjects, who were for 3 male Korean national representative judokas(elite group : EG) and 3 male representative judokas of Korean University(non-elite group: NEG), and were filmed 4 DV video cameras(60fields/sec.), that posture of uke were shizenhon-tai (straight natural posture), jigohon-tai(straight defensive posture), VRL of uke was 0%. The selected trials were subject to 3-dimensional film motion analysis and ground reaction force(MRF) analysis. The kinetical variable of this study were temporal, postures( ankle and knee angle of attacking leg), that were computed through video film analysis, MRF at events were obtained from the ground-reaction force analysis by AMTI force plate system. When performing uchi-mata according to each posture and by VRL, from the data analysis and discussion, the conclusions were as follows : 1) Temporal variables : total time-required(TR) when performing uchi-mata was shown EG 0.13sec the shorter than NEG(o.77sec.) in shizenhon-tai. and EG 0.17sec the shorter than NEG(o.76sec.) in jigonhon-tai. Also, all of two groups' jigohon-tai(0.68sec.) were faster than shizenhon-tai(0.71 sec.). 2) The posture variables : The angle of ankle in attacking when performing were plantar flexion in EG, and dorsi flexion in NEG by shizenhon-tai and jigohon-tai posture. The angle of knee in attacking when performing were extension in EG and NEG, but range of extension in EG were larger than in NEG. 3) MRF : Vertical MRF when performing uchi-mata was shown the strongest in the 2nd stage of kake phase(2.23BW) by EG in both posture, and it was same value by NEG(2.23BW), but shizenhon-tai (2.28BW), jigohon-tai(1.64BW), respectively.

문화예술의 하드웨어 구축과 함께 정책적인 차원에서 이를 운영하거나 관리할 수 있는 전문 인력의 양성과 확보에 대한 중요성이 정책적인 과제로 부각되었고, 국민의 문화욕구가 증가하면서 공연예술도 대형화와 전문화로 인해, 대형 뮤지컬의 제작 편수가 많아지고 외국과의 공연교류가 활발해지면서 무대기술 인력의 수요도 증가하였다. 이처럼 공연장이 증가하면서 전문적으로 안전하고 질 높은 공연을 위한 무대 기술 분야의 전문 인력이 요구되었다. 무대예술전문인 자격제도는 무대기술 분야의 직업적 전문성과 안정성을 높여 공연장과 공연 예술의 질적인 발전을 목적으로 하고 있다. 2000년부터 시행되고 있는 이 자격제도는 점차 자리를 잡아가고 있으며, 이 제도가 처음 도입될 당시 무대기술 분야 종사자들은 예술적 전문성을 인정받고 무대예술전문인으로서 자긍심을 높일 수 있을 것이라는 확신을 갖고 많은 관심을 표명하였다. 그러나 정부의 문화예술 전문 인력 양성 확보를 위한 정책적인 방안과 무대기술 분야 인력정책에 대한 관심은 상대적으로 매우 미약하다고 볼 수 있다. 따라서 본 연구는 우리나라의 공연예술 전문 인력 양성을 위한 첫 자격제도로서, 자격제도의 도입 취지와 걸맞은 운영과 역할을 하고 있는지 현황 파악을 통해 문제점을 분석하여 개선방안을 제시하였다.
