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.

본 연구의 목적은 한양대학교(안산캠퍼스) 주변 호수들의 수질과 물의 오염 상태를 조사하기 위해서이다. 수질은 물의 온도, pH 화학적 산소 요구량(CODMn), 총 질소(T-N), 총 인(T-P), 부유물질(SS), 그리고 중금속(Zn, Cd, Pb, Cu, As, Cr(VI), Hg)을 측정했다. 호수들의 수질등급은 환경처에 의해 평가된 등급V보다 더 낮았다. 한양대학교(안산캠퍼스) 주변의 모든 저수지들은 생활폐수, 그리고 산업폐수의 유입으로 이미 심각하게 오염되어 있다. 그러나 중금속의 오염은 관찰되지 않았다. 만약 폐수의 처리가 확립되지 않는다면 한양대학교 주변 저수지들의 수질은 더욱악화될것으로 사료된다. The objective of this study was to investigate the water quality and status of water pollution in the lakes around Hanyang University (Ansan campus). Water quality was determined by monitoring water temperature, pH, chemical oxygen demand(CODMn), total nitrogen (T-N), total Phosphorus (T-P), suspended solids (SS), heavy metals (Zn, Cd, Pb, Cu, As, Cr(VI) and Hg). The level of water quality of lakes was lower than the level V estimated by the Enviroment Ministry. All of the reserviors around Hanyang University (Ansan campus) had been already seriously polluted by inflow of wastewater from residents, animal husbandries and industries. However, heavy metal pollution was not observed. It is recommended to establish plans for water quality improvement for the reserviors around Hanyang University before it gets worse.

북양산 냉동명태를 원료로서 열풍건조법으로 마른명태를 가공하였을 때, 건조중의 핵산관련물질 및 유리아미노산의 변화를 실험하였다. 원료육중에는 inosine 함량이 가장 많아 건물증량 기준으로 13.5μmole/g였고, 다음으로 함량이 높은 IMP였는데 5.1μmole/g로서 비교적 낮은 값이었다. 열풍건조중 IMP는 급격히 감소하여 잔존량은 14%에 불과하였으며, inosine은 건조중 50%감소하였다. 한편 hypoxanthine는 약 5배 증가하여 건물중량 기준으로 16.9μmole/g 였다. 건조후 3개월간 저장중에는 건조직후와 비교할 때 핵산관련물질의 변화는 거의 없었다. 그리고 원료 명태 육중의 유리아미노산 조성은 taurine이 가장 많아 전 유리아미노산의 40%를 차지하고 alanine, glycine, glutamic acid가 그 다음이고 비교적 함량이 낮은 것은 lysine, serine, histidine이며, 함량이 극히 낮은 것은 valine, aspartic acid, threonine, isoleucine, leucine등이었다. 열풍 건조중 유리아미노산의 질적 변화는 없었으며. 원료육 유리아미노산에 대하여 건조중 유리아미노산양이 20% 증가하였다. In this paper, the changes of nucleotides and their related compounds and free amino acid composition of Alaska Pollack muscle during hot-air dehydration and storage for three months were determined. The results showed that the contents of inosine and IMP in defrosted sample were 13.5 and 5.1 μmole/g respectively on dry base, and followed by hypoxanthine in order. ATP, ADP and AMP was very low in content. IMP and inosine tended to degrade rapidly during hot-air dehydration while hypoxanthine increased about five times. But the quantitative changes of nucleotides and their related compounds in the muscle of hot-air dehydrated Alaska Pollack during storage were not detected. Taurine was abundant in the muscle extracts, showing 40% of the total amino acid content and followed by alanine, glycine and glutamic acid. Lysine, serine and histidine were low in content respectively, and valine, aspartic acid, threonine and leucine were very poor. The qualitative change in the pattern of free amino acid composition of muscle extracts was not observed during hot-air dehydration. The increase of the total free amino acid during hot-air dehydration was approximately 20%.

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.
