본 저자들은 인위적인 인슐린 투여로 인한 인간성 저혈당증 1예에서 보존적인 치료로 의식기능은 회복하였으나, 현저한 인지능력 저하를 하였기에 문헌고찰과 함께 보고하는 바이다. Factitious hypoglycemia is a covert attempt to lower the blood glucose concentration with insulin or a sulfonylurea agent. This attempt is mainly performed by the patients themselves. In a large series of diabetics who had overdosed on drug, less than 5% had used insulin for suicidal or homicidal purposes. Additionally, 4 of 204 hypoglycemic episodes were due to a suicide attempt with insulin. The onset of insulin action, its peak level, and duration, and the degree of hypoglycemia, are determined by insulin's pharmacokinetics. However, the final outcomes are not associated with the amount of insulin used. The complications related to insulin overdose are cerebral damage and hypokalemia. Other complications include, pulmonary edema attributed to congestive heart failure and hypertensive crisis, as well as respiratory insufficiency. We report this case with a review of the literature.

Benzo(a)pyrene 독성에 의한 사람 림프아 세포(NC-37)에서 c-myc 유전자의 발현

하봉준,정인철,곽충근,조무연 고신대학교 의학부 1996 高神大學校 醫學部 論文集 Vol.11 No.1-2

To investigate expression in c-myc gene by a chemical carcinogen benzo(a)pyrene(BP), human lymphoblast NC-37 cells were exposed to various concentrations of BP and the c-myc gene expression was evaluated by northern and slot blot hybridization methods. When NC-37 cells exposed to BP of 0-4㎍/ml were treated with HindⅡ/XbaⅠ restriction enzyme, the c-myc genes were cut at the same region regardless of BP concentration. The site of cleavage by the restriction enzyme, HindⅡ/XbaⅠ was identical in the control, BP-treated and BP-washed cells. However, the m-RNA expression in slot blot hybridization appeared to be 4-5 times higher in BP-treated cells than in the control, and this effect was partially removed by washing the BP. When the DNA isolated from NC-37 cells exposed to various concentrations(0, 2, 4㎍/ml) of BP were amplified by polymerase chain reaction using a primer containing c-myc exon Ⅰ, the resulting DNA were of the same size in all groups. These results suggest that overexpression of c-myc oncogene may be required for the malignant transformation and maintenance in benzo(a)pyrene poisoned human lymphoblast NC-37 cells.

In order to find out the runoff characteristics in Nam River Dam basin, hydrological data such as rainfall, water level, and discharge, have been collected and measured. Using the collected and measured data for the study area during 1990-1999, hydrological parameters were estimated. The HEC-HMS(Hydrologic Modeling System) model was used to review the applicability of flood hydrographs and the results of simulation were compared to the observed data and Stroge Function Method for several flood hydrographs in this study. From the results of analysis, the following conclusions were obtained: First, the HEC-HMS model showed better results for the capabilities of regenerating flood hydrographs Second, the fluctuation shape of flood hydrographs for the rainfall distribution concentrated on head have been shown peak time to be relatively short for other rainfall distribution. Third, for forecasting and warning of flood occurrence in future, it is necessary that the existing hydrological data were made good and hydrological data were accumulated more. Also, using the HEC-HMS model to complement the Storage Function Method, it is possible that forecasting and warning flood occurrence is progressive in Nam River Dam.

대형구조물의 용접시 잔류변형과 잔류응력은 구 구조물의 모양과 크기, 그리고 구속조건에 따라 크게 달라진다. 따라서, 대형구조물의 잔류응력에 대한 정확한 해석을 위해 용접 잔류응력 및 용접 잔류변형을 정확히 예측할 수 있는 적절한 유한요소해석 절차의구현이 필요하다. 본 연구에서는 용접 잔류응력과 변형률의 존재를 예측할 수 있는 열전달 해석 및 열탄소성 해석과 같은 적절한 유한요소해석 과정을 찾고자 한다. 해석을 위해 아크의 열원에 대한 가우시안 분포를 가정하고 용접부의 상변화에 대한 엔탈피모델을 선정한다. 그리고, 대형구조물의 열전달해석을 위해 Remeshing기법을 이용한 유한요소모델의 생성이 필요하다. 끝으로, 개발된 해석과정은 단순맞대기 용접에 대해 적용해 보았고, Remeshing 기법은 컴퓨터 자원에 대한 절약 측면에서 상당한 효과를 나타내었다. Welded structures experience changes in shape, size and constraint conditions after favirication due to internal residual stresses. For the accurate simulation of the typical welding procedure, transient heat transfer analysis as well as thermal-elasti-plastec analysis should be employed. In this paper, appropriate finite element analysis procedures that can predict welding residual stresses and strains are presented. Gaussian distribution of arc heat source is assumed andenthalpy model is employed for phase change of the welding zone. Finally for the purpose of applying the developed technique to large scale structrues, remeshing techniques by successive generation of finite element model are given for that transfer analysis. The developed analysis procedure are tested for the simple butt welding which gives reliable results. Remeshing techniques are also tested against the existing mesh pattern which showed considerable reduction in computational resources.
