N/A The process of solidification of metal is accompanied by liquid-solid change and known as Stefan`s heat conduction problem on the moving boundary. In this study the temperature distribution in ingot and metallic mould during casting was analyzed by the two dimensional heat conduction theory. The transient temperature distribution was numerically calculated using a finite element method on the nodal point of mesh screen representing ingot and mould cross section. The theory was applied on the casting of aluminum(purity ; 99%) in flat ingot mould of GC25. The analysis will make it possible to calculate an optimum mould shape of which temperature gradient becomes minimum.
낮은 자기통제력의 결과로서의 청소년비행과 학교에서의 징계경험
민수홍 한국청소년학회 2005 청소년학연구 Vol.12 No.2
This study examines the self-control theory(Gottfredson and Hirschi, 1990) with the Korea Youth Panel Survey data, the first national panel data about Korean adolescents. Self-control was measured by adding one more element of "lack of possession of and appreciation for cognitive or academic skills and planning" to the 6 elements what Grasmick et al.(1993) suggested. Overall, the test results support the claims of the self-control theory. Research findings show that 8th grade girls' self-control level is higher than that of the 8th grade boys. Test results also show that boys and girls low on self-control are more likely than others to have committed crime, delinquency, and computer-related deviance, a new form of juvenile delinquency. Findings show that adolescents low on self-control are more likely to be punished by the school authority for their delinquency. 본 연구는 갓프레드슨과 허쉬(Gottfredson and Hirschi, 1990)의 자기통제이론을 국내에서 처음으로 전국적인 자료를 가지고 검증하고, 자기통제력을 기존의 연구들과 달리 7개의 하위영역으로 구성함으로써 청소년에게 적합한 측정을 시도하였다. 분석을 통해서 이론이 주장한대로 여자 청소년의 자기통제력이 남자 청소년보다 높다는 점이 검증되었다. 자기통제력은 청소년의 지위비행, 범죄, 남 괴롭히기를 설명하였고 신종 비행이라고 할 수 있는 컴퓨터 관련 일탈도 설명하는 것으로 밝혀졌다. 학생들이 학교에서 받는 징계경험에도 자기통제이론이 적용될 수 있음이 확인되어져서 학교의 징계가 학생의 사회경제적 특징에 근거해서 일방적으로 주어지는 낙인이 아니고 개인차원의 특징인 낮은 자기통제력에 대한 반응이라는 점을 알 수 있었다.
消化性潰瘍 및慢性胃炎에 對한 Basic Alminum Sucrose Sulfate(Ulcerlmin)의 臨床的 觀察
閔壽泓,李相允,洪珍淑 최신의학사 1972 最新醫學 Vol.15 No.7
Basic alminum sucrose sulfate (ULCERLMIN) is combined with pepsin to form ULCERLMIN-pepsin complex and inhibits the proteolytic activity of pepsin. Furthermore, it has gastric mucosal protection activity since it forms the complex, being combined with gastric mucosal protein. It also possesses antacid activity and has been applicated to the treatment of peptic ulcer. In this report, Ulcerlmin was used as a treatment of peptic ulcer and chronic gastritis, and the results were as following. The excellent or good results were obtained in the majority of cases of peptic ulcer. The good results were obtained in superficial types and hypertrophic types of chronic gastritis but in atrophic types, the results were poor.

In this report, total lipid, phospholipid, total cholesterol and cholesterol ester(%) of the serum lipids were measured on the 57 cases of acute viral hepatitis admitted to the department of gastroenterology of this hospital. The following results were obtained through the correlations with the routine liver function tests and serum lipids. 1. On the 57 cases of acute viral hepatitis the decrease of total lipid was frequently noted on 44 cases(77.2%). Whereas, the increase of phospholipid was observed on 36 cases(63.2%). The majority of cases had total cholesterol and cholesterol ester(%) of within normal limit. 2. In the relations between serum lipid and the blood chemistry, there was a significant correlation between not only the increase of α₁ and α₂-globulin and that of total lipid but also the positive of thymol turbidity test and that of total lipid. 3. The increase of phospholipid were correlated with the decrease of albumin and the A/G<1.0. 4. The meaningful correlations exist among the increase of total cholesterol and the increase serum iron, and there was a correlation between the decrease of total cholesterol and the decrease of albumin. In the cholesterol ester(%) the significant correlations exist among the decrease of ester form, the inrcease of bilirubin and the decrease of total protein.
