However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

Pore structure and acid absorbancy of carbon electrode of phosphoric acid fuel cell were studied by varying carbon black, PTFE loading, and fabricating method for Denka black. Results showed that the primary pore(micro pore) of the carbon electrode included the micro space formed around the carbon particles regardless of the carbon black(Vulcan XC-72 and Denka black) used, and that addition of PTFE and pressing of electrode influenced mainly the secondary proe. The acid absorbancy of electrode was decreased as PTFE loading was increased and Denka black showed more hydrophobic than Vulcan XC-72 with three times in saturation time and one-half in acid absorbancy.

Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.

물관리방법을 달리한 상시담수와 간단관개에서 메탄과 아산화질소의 배출 양상과 서로 다른 종류의 유기물원 및 질소비료 시용에 따른 메탄과 아산화질소 배출을 비교하고 저감 할 수 있는 방법을 찾기 위해 본 시험을 실시하였다. 물관리방법으로는 상시담수 (이앙∼출수 35일까지 담수)와 이앙 35일 이후 중간낙수한 간단관개 (중간낙수기간 20일),그리고 시비방법으로는 토양을 검정한 시비량인 토양검정, 토양 검정시비량+볏짚 돈분액비, LCU 완효성비료 그리고 N을 시용하지 않은 대조구 등을 처리하여 메탄 및 아산화질소 배출량을 측정하였다. 메탄 배출량은 간단관개보다 상시담수에서 높았고, 아산화질소 배출량은 이와 반대로 나타났다. 유기물과 비료시용 종류에 따른 메탄과 아산화질소 배출량은 액비와 검정시비+볏짚시용구에서 가장 높았으며, LCU 완효성비료구에서 가장 낮았다. 지구온난화잠재력으로 환산한 온실가스 배출은 물관리 조건에서 상시담수가 간단관개보다 170∼208% 높았으며, 요소를 시용하고 상시담수를 기준 한 것과 간단관개로 물 관리하여 각 처리에 따라 온실가스 배출을 비교하면 요소는 41.4%, LCU 완효성비료 55.8%로 온실가스 배출을 줄일 수 있는 것으로 나타났다. 그리고 비료이용효율은 LCU완효성비료, 액비>검정시비+볏짖>검정시비 순이었다. Emission of methane and nitrous oxide affected by nitrogen fertilizer materials were measured simultaneously in rice paddy fields under flooding and intermittent irrigation in 2000. Studies focused on mitigating CH_4 emission from rice paddy fields are summarized and the possibilities and limits applied to world's rice cultivation are discussed. The mitigation options are water management, soil amendments, organic matter management, different tillage, rotation, and cultivar selection. Altering water management, in particular promoting midseason aeration by short-term drainage, is one of the most promising strategies, although these practices may be limited to the rice paddy fields where the irrigation system is well prepared. The test site was divided into two water managements: a continuously flooded plot which was maintained flooded by constant irrigation from May to September, and an intermittently drained plot in which short-term (20days) draining practices were performed one times during the flooding period. By total emission of GHGs converted by global warming potential (GWP), flooding plots were higher 170~208% than intermittent irrigation plots. For emission of GHGs in fertilizer materials, it was high in the order of Swine slurry>Urea+Rice straw>Urea>LCU. Basing on GHGs emission of urea fertilization under flooding as baseline GWP of urea fertilization and Latex-coated urea under intermittent irrigation showed lower GHGs emission by 41.4% and 55.8%, respectively. In this case fertilizer use efficiency (kg unhulled rice/kg of applied N) were 18.2~20.2 and 18.7~19.0 and 9.3 and 5.8~6.6 for Swine slurry and LCU and Urea+Rice straw and Urea in the continuously flooded and intermittently drained plot.

Even after tremendous effort on software productivity enhancement, actually no proper project evaluation was in presence up until today. On this thesis, I have developed a criteria tool for evaluation on software production enhancement. For this tool, I have implemented functional point as primary production guideline, FP/MM or W/FP has been utilized for fundamental productivity index and for FP calculation method, the IFPUG guidance has been applied. In addition to that, based upon the results on SI division, project division, size and productivity using developed index, no significant difference in productivity level was found on respective entities. However, it happened to be as a project size increases its production level decreases.

교류분석프로그램을 통한 비행청소년의 교정처우에 관한 연구

As counterplans of the prevention and the treatment of juvenile delinquency are so diversified and so far reaching, we can't systematically inquire into them. But they shall be obtained when we see through idea and principle of the prevention and the treatment. Furthermore we can inspect rationality, reason and equivalency of counterplans, even though incompletely. In supplement when understanding the process of the prevention and the treatment as totally one system, we can adopt the method, which combines functionally counterplans of each agencies and establishes collective responsibility among agencies. In this work above mentioned method is used in the judicial administrative process. As a result it is said that the prevention and the treatment shall be succeeded when groups and mechanism, which boys are exposed to, do their native functions with faithfulness. In other words it means that, when not only the modern functions of home, school, company and police but also, macroscopically seen, that of the legislature be achieved, the problems of juvenile delinquency will fairly diminished. And it can't be despised that we must regard the solution of seriousness of juvenile delinquency and wrongdoing as our responsibility and endeavour efforts to educate them and make them adjust themself to society. In order to do this responsibility, national disposition that enables us to recognize simultaneously the fruition of boy patronage idea and the solution of problems, which boys confront with, as our responsibility, is claimed.
