혈중 셀레늄 농도와 위장질환과의 관련성을 밝히기 위해, 1986년 7월에서 9월 사이에 대구시내 2개 대학병원 외래를 방문하여 위내시경검사를 받은 사람들 중에서 간장질환, 신장질환, 식도정맥류 및 십이지장질환을 제외한 175명을 대상으로 일반적 특성을 조사하고, 정맥혈 5ml를 채취하여 flameless atomic absorption spectrophotometry를 이용하여 혈중 셀레늄농도를 측정하였다. 평균 혈중 셀레늄농도는 위염($155.5{\pm}14.0{\mu}g/{\ell}$), 위궤양($154.8{\pm}29.3{\mu}g/{\ell}$) 그리고 위암($133.0{\pm}8.4{\mu}g/{\ell}$)으로 모두가 위내시경 음성군($173.3{\pm}33.6{\mu}g/{\ell}$) 보다 통계적으로 유의하게 낮았다(p<0.05). 남성에서도 위염, 위궤양 그리고 위암 모두는 통계적으로 유의하게 낮았지만(p<05), 여성에서는 위염과 위암이 음성군 보다 유의하게 낮았고(p<0.05), 위궤양은 평균 혈중 셀레늄농도가 $177.7{\mu}g/{\ell}$로 음성군($169.7{\mu}g/{\ell}$)보다 높았지만 통계적으로 유의하지는 않았다. McGee의 LOGRESS Program에 의한 logistic분석에 있어 혈중 셀레늄농도의 계수는 위염과 -0.0436(p<0.05 ; odds ratio 0.957), 위궤양과 -0.0197(p=0.17 ; 0.981), 위암과 -0.4876(p<0.05 : 0.614) 그리고 위장질환 전체와는 -0.0411(p<0.05 ; 0.960)이었다. 이상의 성적은 비록 그 검사예수가 적지만 위염, 위궤양 특히 위암에 있어서 혈중 셀레늄농도가 위내시경 정상 소견을 보인 예에 비하여 낮았다는 사실은 혈중 셀레늄과 몇가지 위장질환과는 어떠한 관련성을 시사하는 자료가 된다고 하겠으며 추후 많은 추적검사가 필요할 것으로 보인다. (본 논문의 자료 수집을 위해 협조해 주신 경북의대와 계명의대 내과학교실 및 임상병리학교실 여러 선생님께 깊은 감사를 드립니다. 또한 셀레늄 분석과 원고 교정을 도와준 장봉기 선생과 자료의 통계처리를 도와준 천병렬선생께도 뜨거운 감사를 드립니다.) To reveal the association between blood selenium level and the gastric diseases, 180 persons received the gastrofiberscopic examination at the outpatients department of the two university hospitals from July to September 1987, after the exclusion of the persons having the esophageal varix, were randomly selected. Their general characteristics such as age, sex and educational level and so on, were inverstigated. Five mi venous blood was collected from each subjects and stored at $0^{\circ}C$ in heparinized vaccum tube. The blood selenium level was measured by the flameless atomic absorption spectrophotometry. In the procedure of data analysis, five subjects having benign tumor and anomaly of the stomach, were also excluded. The mean blood selenium levels of the $155.5{\mu}g/{\ell}$ among gastritis cases, the $154.8{\mu}g/{\ell}$ gastric ulcer and the $133.0{\mu}g/{\ell}$ gastric malignancy were significantly lower(p<0.05) than that of the $173.3{\mu}g/{\ell}$ among normal controls. In men the mean blood selenium levels .among gastritis, gastric ulcer and gastric malignancy cases were significantly lower(p<0.05) than that among normal controls. In females, the mean blood selenium levels among gastritis and gastric maligancy cases were significantly lower(p<0.05) than that among normal controls($169.7{\mu}g/{\ell}$), but that among gastric ulcer cases($177.7{\mu}g/{\ell}$) was not significantly higher. In the logistic analysis, coefficient of the blood selenium level was -0.0436(p<0.05 : odds ratio 0.957) for gastritis, -0.0197(p=0.17 : 0.981) for gastric ulcer, -0.4876(p<0.05 : 0.614) for gastric malignancy and -0.0411(p<0.05 ; 0.960) for gastric diseases including the gastritis, the gastric ulcer and the gastric malignancy. These data support the hypothesis that the gastric diseases are to be associated with the low selenium level but, for the gastric ulcer, the further research is recommended.

The government make a mandatory to submit a decommissioning plan to the regulatory body as decide to decommissioning of the GORI 1 NPP. The decommissioning plan requires various kinds of expert knowledge. But it has not been developed yet. This paper proposes a new type of a decommissioning decision-making support model that can evaluate the main factors based on quantitative and qualitative data for decommissioning a full life-cycle reactor. The proposed model is a technology that can trace the change in dismantling costs and a change history of dismantling methods following a decommissioning regulatory changes as a model combined a decommissioning engineering system and requirement engineering. The model will be showed an advanced knowledge base as linked with laws and an important factors for decommissioning of a NPP.

N/A Today upper gastrointestinal (UGI) endoscopy is widely used in diagnosis and management of foreign bodies. A clinical study of 76 cases with the foreign bodies in the upper gastrointestinal tract diagnosed by flexible UGI endoscopy in Dangsan Hospital from January 1982 to December 1992 was performed. Foreign bodies were common in male (rate 1,6: 1) and in 6th decade (28 cases, 36.8%). Bezoar was the most common foreign body (57 cases, 75.0%) and foreign bodies were mostly lodged in stomach (50 cases, 65.8%). Endosopic removal or destruction was successful in 31 cases (35.4%) including all 19 cases other than bezoar. 52 cases (68.4%) hacl combined diseases, 17 cases (22.4%) had past history of operation and 9 cases (11.8%) had history nf ingestion of foreign bodies. In conclusion, UGI endoscopy and endoscopic removal is required to diagnose and manage foreign bodies in UGI tract
