Sclerosing encapsulating peritonitis (SEP) is characterized by peritoneal fibrosis and adhesion of the peritoneum with the loops of the small intestine. Although the prevalence is low, most cases are caused by peritoneal dialysis, infection, medication, systemic lupus erythematosus (SLE), and intra-abdominal neoplasm. We describe a 22-year old man who was presented with abdominal pain and distension, which were attributed to SLE with peritonitis. He had no specific history of previous medical illness and peritoneal dialysis. He was treated with intravenous high dose methylprednisolone 1 g/day for 3 days, followed by intravenous methylprednisolone 1 mg/kg daily and immunoglobulin. However, his symptoms did not improve. Eventually, a laparoscopic biopsy was performed for an accurate diagnosis. The histopathologic findings were presented in accordance to the typical characteristics of SEP. In spite of medical treatment, he did not show an improvement of clinical symptoms and radiologic findings. As a result, he died from nutritional deficiency, upper gastrointestinal bleeding, and congestive heart failure.

본 연구는 여고 유도선수들의 경기력 향상을 위해 유도종목의 특성과 훈련형태를 고려하여 개발한 16주간의 주기화 근력 트레이닝 프로그램을 적용한 후 체격 및 체력의 변화를 검증하는데 그 목적이 있다. 본 연구의 대상은 연구 중 중도탈락과 부상 등의 이유로 5명을 제외한 평균연령 17.4±.96세, 평균신장 161.7±5.51cm, 평균체중 62.8±13.3kg인 여고 유도선수 총 25명을 대상으로 유도 경기력 관련 체격이나 체력의 향상 효과를 프로그램적용 전·후 즉 사전-사후 각 항목의 평균차이를 비교하고 통계적 검증은 paired t-test를 실시하였다. 주기화 근력 트레이닝 프로그램을 여고 유도선수에게 적용한 결과 사전과 사후의 체격 및 체력의 변화 검증에서 다음과 같은 결과가 도출되었다. 신체조성에서 체지방률은 변화의 패턴이 나타나지 않았으며, 최대근력(1-RM)의 측정을 위한 벤치프레스 결과를 보면 근파워의 차이에서 약 2.5kg이상 근파워가 증가한 것을 확인할 수 있었다. 또한 스쿼트의 결과에서도 통계적으로 유의한 차이가 있었으며, 약 15.4kg이 증가한 것을 확인하였다. 이러한 결과는 여고 유도선수들에게 적용한 주기화 근력 트레이닝 프로그램이 효과가 있었던 것으로 판단된다. 향후 본 연구의 주기화 근력 트레이닝 프로그램의 효과를 검증하기 위해 주기화 근력 트레이닝 프로그램을 적용하지 않은 대조군과의 비교가 필요하며, 매트훈련과 연관된 동작이나 자기 체중을 이용한 체력훈련 프로그램 등을 개발하여 근력 트레이닝과 함께 실시한다면 유도경기의 특성인 중심이동을 원활하게 할 수 있는 동적인 트레이닝을 수행할 수 있을 것이다. This research aims at applying the 16-week periodic muscular strength training program developed by taking the characteristics and training forms of judo into consideration to the field in order to enhance the athletic performance of judo players in girls` high schools and at verifying its effects. The research subjects were 25 judo players from girls` high schools, whose average age was 17.4±.96, average height 161.7±5.51cm and average weight 62.8±13.3kg, except the five players who were injured and dropped out during the research. With regard to the improvement in their physique and athletic performance relevant to judo performance, the differences in the averages of each item before and after applying the program, that is, the preliminary and post tests, were compared, and a paired t-test was conducted to examine them statistically. When the periodic muscular strength training program was applied to the judo players in girls` high schools, the following result was deducted from the tests on the differences in the physique and athletic performance before and after the application. In the body composition, no pattern of change was found in their body fat percentages, and the bench-press result to measure the maximum muscular strength (1-RM) proved that their muscular power increased by more than about 2.5kg. In addition, a statistically meaningful difference was found in the result of squats, and about 15.4kg was confirmed to have increased. These results showed that the periodic muscular strength training program applied to the judo players in girls` high schools was effective. For more effective application of the periodic muscular strength training program developed in this research, if some movements related to mat training or a strength training program where their own weight is used are developed and performed along with the muscular strength training, a dynamic training which helps judo players move cores smoothly, one of the features of judo games, will be able to be conducted.

This study simulated the shock wave propagation through the tamping material between explosives and hole wall at blasting works and verified the effect of tamping materials. The Arbitrary Lagrangian-Eulerian(ALE) method was selected to model the mixture of solid (Lagrangian) and fluid (Eulerian). The time series analysis was carried out during blasting process time. Explosives and tamping materials (air or water) were modeled with finite element mesh and the hole wall was assumed as a rigid body that can determine the propagation velocity and shock force hitting the hole wall from starting point (explosives). The numerical simulation results show that the propagation velocity and shock force in case of water were larger than those in case of air. In addition, the real site at blasting work was modeled and simulated. The rock was treated as elasto-plastic material. The results demonstrate that the instantaneous shock force was larger and the demolished block size was smaller in water than in air. On the contrary, the impact in the back side of explosives hole was smaller in water, because considerable amount of shock energy was used to demolish the rock, but the propagation of compression through solid becomes smaller due to the damping effect by rock demolition. Therefore, It can be proven that the water as the tamping media was more profitable than air.
