내시경적 역행성 담췌관조영술 후 발생한 급성췌장염의 발생인자로 여러 가지 인자들이 관여하지만 특히 담췌관조영술 시행 후 과도한 췌선방 조영화에 의한 중증의 췌장염 증례를 경험하였기에 보고하는 바이다 Endoscopic retrograde cholangiopancreatography (ERCP) has been considered as a valuable tool for the diagnosis and management of disease of the pancreas and biliary tree. Post-ERCP pancreatitis is the most frequent and clinically significant complication following ERCP. But a few complication associated with this procedure are unforeseeable. Specially, acinarization as a result of a careless cooperation between operator and assistant may be influenced in complications of ERCP. Severe post-ERCP pancreatitis is rare complication, and its prognosis will be poor. Therefore, careful process and good relationship between operator and assistant in ERCP may be prevented this complication, but is not clear. Neglect of acinarization may be resulted in more aggravation of pancreatitis. We have cared for one patient with severe post-ERCP pancreatitis with pseudocyst after water-soluble contrast media spreading into the acini (acinarization) via ERCP in resolving phase idiopathic pancreatitis.

알칼리형 연료전지(Alkaline fuel Cell, 이하 AFC)의 산소극에 사용되는 촉매를 은 염의 화학적 환원법으로 제조하였다. 그리고 최적의 전극 제조 조건을 찾기 위해 촉매의 loading량, 전극 소결 온도, PTFE함량 및 촉매 입자 크기 등이 전극의 분극특성에 미치는 영향들이 조사되었다. 연구결과에 의하면, 최적 조건은 전극 소결 온도 350℃, PTFE 함량 9wt%, 촉매의 입자크기 68㎛ 이하이었다. 한편 촉매 loading량이 증가함에 따라 전극 성능이 향상되었다. 최적의 제조 조건에서 제작된 전극은 개회로 전위 1.11V(vs. RHE),200㎷ 분극(전극전위 0.91V vs. RHE)시 전류밀도 약 0.4A/㎠,300㎷ 분극 (전극전위 0.81V vs. RHE)시 전류밀도 1.0A/㎠의 성능을 나타내었다. Doped silver catalyst used for oxygen electrode in alkaline fuel cells was prepared by reduction method of silver salt. And the effects of the silver catalyst loading, electrode sintering temperature, content of PTFE and particle size of the catalyst on the polarization characteristics of the oxygen electrodes were investigated to find the optimum preparation conditions of the electrodes. According to the results of this work, the optimum conditions were sintering temperature of 350℃, PTFE content of 9 wt% and below catalyst particle size of 68 ㎛. On the other hand, with increasing the catalyst loading, the electrode performance was improved. The electrode prepared at the optimum conditions showed open circuit potential of 1.11V(vs.RHE), current density of 0.4A/㎠ at a overpotential of 200㎷ and 1.0A/㎠ at a overpotential of 300㎷.

The chorion protein (A, B, C, D, E, HcA, HcB) are synthesized by monolayer of follicular epitherial cells and assembled after secretion into eggshell in B. mori. The chorion gene contains 15-multigene families (the pair-HcA, HcB) which are divergently oriented gene pairs in B. mori. The chorion protein of B. mandarina (Korean wild silkmoth) apparently differ those of B. mori in the structure, morphology and protein secondary structure. The chorion gene of B. mandarina have few been studied yet. We've studied the chorion gene of B. mandarina, constructed wild silkmoth genomic library and obtained the 10 Hc clones. 8 clones are sequenced and characterized (some are partial sequence). The sequence similarities of B. mori and B. mandarina of each families are 90% and 85% respectively. Some of them are changed the charge of amino acids in the terminal of central domain. The variable region of C-arm is composed of Cys-Gly, Cys-Gly-Gly repeated structure which determines the length variation in B. mandarina.. It means the genetic exchanges are occurred in the region among multigene families. We could find the structural and evolutionary relationship.

Spontaneous esophageal rupture (Boerhaave's syndrome) is a rare case that require early diagnosis and treatment because of its high mortality. The oral administration of osmotically balanced polyethylene-glycol-based electrolyte preparation is a commonly prescribed preparation for cleansing in patients undergoing colonoscopy. Nausea, vomiting and abdominal pain are frequently seen, but serious adverse reactions are rare. Esophageal rupture secondary to severe vomiting, which occurred during colonoscopy preparation using polyethylene gIycoI(PEG) electrolyte solution is extremely rare and only few cases have been published in the literature. We report a case of spontaneous esophageal rupture after routine administration of the PEG before colonoscopy. 대장 정결을목적으로 PEG 사용 후 아주 드물게 발생하는 Boerhaave 증후군 1예를 경험하였기에 보고하는 바이다.

There are many college in born and university in rapid extention in a short time, after 1980s, in Korea, and the structure of the school and department should be lack in the goal of ideal environment as a campus. The campus of the new college to be accomplished by incremental process, in special, have an undefined goal of the structure and character of the school, and it is difficult to escape from the uncertainity of the structure, and cause a missing goal of campus planning and decision-making. In order to trace the undefined process, this article are analyses the campus planning and the construction process of Dongshin University in Naju city, as a case study, its result can be used to get final campus environment. In this article, we can see the process and decision-making by incremental planning and building, and a proposal for remaking of Dongshin University master planning are supplemented.

ZnO/ZSM-5상에서 저탄소가의 탄화수소로부터 방향족화의 성능향상

n-헥산의 방향족화 반응에서 HZSM-5에 기계적으로 혼합 첨가된 ZnO의 영향을 연구하였다. n-헥산의 방향족화 반응에 있어서, HZSM-5 자체 만으로도 활성을 나타냄은 물론 HZSM-5에 ZnO가 첨가됨에 따라 활성이 더욱 증대되었다. 이는 ZnO/HZSM-5에서의 방향족화 반응은 이원 기능 과정임을 나타내는 것으로서, 이때 ZnO의 역활은 n-헥산의 탈 수소 반응을 촉진하는 것으로 생각된다. 첨가된 ZnO는 촉매의 산도, 결정성 및 표면적에는 거의 영향을 주지 못하는 반면, 전화율과 방향족 화합물로의 선택도와 같은 촉매 활성에는 많은 변화를 주었다. 그러나, 무엇보다도 중요한 것은 급격한 촉매 활성의 저하를 방지하는 것이라 할 수 있다. The effect of ZnO added to HZSM-5 catalyst by mechanical mixing in aromatization of n-hexane has been studied. It is shown that HZSM-5 alone is active for aromatization of n-hexane and the activity is enhanced by addition of ZnO to the HZSM-5 catalyst. This suggests that the aromatization on the Zno-added catalysts(ZnO/HZSM-5) is a bifunctional process, in which ZnO seems to catalyze the dehydrogenation of n-hexane. Addition of ZnO makes less change in acidity, crystallography and surface area, but leads to significant change in activity in terms of conversion and selectivity toward aromatics. What is more important, however, is that it prevents the rapid decay of catalyst-activity.

Exercise index(EI) was measured on 933 pneumoconiosis patients (865 patients with small rounded opacities and 68 patients with large opacities) and 176 suspected pneumoconiosis patients from Korean anthracitic mines, in order to evaluate the ventilatory impairment of pulmonary function according to the chest radiographic findings of pneumoconiosis. Exercise index was obtained from the maximum breathing capacity (MBC) and the exercise ventilation volume(EV) which were measured by spirometer and two step-test. Classification of pneumoconiosis was based on the international classification of ILO U/C. The results were as follows: 1. The mean value of E1 was significantly increased in pneumoconiosis patients with large opacities(46.0%) than in patients with small rounded opacities(26.5%) and with suspected pneumoconiosis(25.0%). The number of jpatients in substandard EI was 97.1% in patients with large opacities but 49.4% in patients with small rounded opacities and 40.3% in patients with suspected pneumoconiosis. 2. The mean values of EI and the number of patients in substandard EI were markedly increased in pneumoconiosis patients with small rounded opacities and suspected over 50 years of age. However, the number of patients in substandard EI showed no association with age in pneumoconiosis patients with large opacitis. 3. In pneumoconiosis patients with small rounded opacities, the mean values of EI and the number of patients in substandard EI showed significant association with the profusion (category) but no significant association with the type of small rounded opacities. 4. In pneumoconiosis patients with large opacities, the mean values of EI and the number of patients in substandard EI showed no significant difference between patients complicated with and without pulmonary tuberculosis. 5. No significant association of EI and the number of patients in substandard EI with the size of large opacities was observed in pneumoconiosis patients with large opacities, however, the mean values of EI showed increasing tendenccy in category B and C compared to category A.
