장희순(Hee Soon Chang),이영(Young Lee) 한국아동학회 1990 아동학회지 Vol.11 No.1
The present research investigated scholastic self-concepts and attribution tendencies of institutionalized children in comparison with home-reared children. The subjects were 286 institutionalized and 327 home-reared fifth, sixth, seventh, and eighth grade children. Instruments were the Scholastic Self-concept Test(Park, Lee, & Cho, 1980), the Attribution Tendency Test(Lee, 1983) and a questionnaire constructed by the researcher. Data were analyzed by ANOVA, Duncan`s Test of Multiple Comparsion, and product-moment correlation coefficient(r). Findings showed that (1) the scholastic self-concept of institutionalized children was lower than that of home-reared children; (2) higher scholastic self-concept of institutionalized children was correlated with (ⅰ) higher degree of contentment with the institution, (ⅱ) shorter length of residence in the institution, and (ⅲ) older age at admission to the institution; (3) institutionalized children attributed achievement more to uncontrollable, external factors, while home-reared children attributed achievement more to controllable, internal factors; (4) institutionalized children with a lower degree of contentment with the institution attributed achievement to luck while those with a higher degree of contentment attributed achievement to ability; and (5) the higher the scholastic self-concept, the higher the tendency to attribute achievement to internal, controllable factors, and the lower the scholastic self-concept, the higher the tendency to attribute achievement to external, uncontrollable factors.

Purpose: Several recent studies have reported on the clinical importance and prognostic significance of neutrophil-to-lymphocyte ratio (NLR) in gastric cancer. The objective of this study was to identify the subgroups of patients with gastric cancer for which the preoperative NLR was prognostically significant. Methods: Data from 870 patients who were among those who had undergone surgery for gastric cancer between August 2005 and December 2013 were evaluated. Receiver operating characteristic curve analysis was used to determine the cut-off value for NLR. The patients were classified into high-NLR (NLR≥1.7) and low-NLR (NLR<1.7) groups, and survival analysis of subgroups of gastric cancer patients was performed. Results: Univariate analysis identified age, gender, tumor location, tumor histology, tumor, node, metastasis (TNM) stage, and NLR as significant prognostic factors. Multivariate analysis identified age, TNM stage, and NLR as significant prognostic factors. In subgroup analysis, NLR was a significant prognostic factor except group of TNM stage I, II with age younger than 70 years. Conclusion: Except group of TNM stage I, II with age younger than 70 years, careful postoperative follow-up is warranted for those patients with elevated NLR.

Methionine 이성질체들의 99mTc 착물 제조 연구
오옥두(Ok Doo Awh),장희순(Hee Soon Chang),이동선(Dong Sun Lee) 대한핵의학회 1992 핵의학 분자영상 Vol.26 No.1
N/A Tc-99m-Methionine complexes from enantiomeric and racemic methionines were prepared controlling reaction parameters such as pH and the concentration of stannous chloride. Some radiochromatographic systems were also examined to determine the labelling yields of Tc-99m complexes. The best resolutions of Tc-99m complexes were obtained at ITLC-SA developed with acetone and paper chromatography with n-butanol saturated with 0.3N HCI. In the former system, HR-Tc-99m and Tc-99m-methionine complex remained at origin, while 99mTcO4 moved with Rf value of 1.0. In latter process, HR-Tc-99m stayed at the origin, while 99mTcO4 and Tc-99m- methionine complexes moved with Rf value of 0.5. By combining of two chromatographic systems, the contents of three Tc-99m species were calculated easily. Tc-99m Labelling from enantiomeric and racemic methionines had little differences and the optimal condition was found at pH 9.00 and the molar ratio of methionine to stannous chloride od 24:1. The yields of Tc-99m complexes from D-, L-, and DL-methionines were 87.6%, 94.1%, and 97.9%, respectively. The results indicated that methionine containing relatively hydrophobic methylthio group (-SCH3) would be labelled with Tc-99m by stannous chloride method.

서울大學校 看護系와 非看護系 女學生들의 價値觀에 관한 比較硏究
張希純,金梅子 中央醫學社 1977 中央醫學 Vol.32 No.3
The Purpose of this study was threefold: 1) to find out some characteristics of nursing students of S.N.U., 2) to compare the value-orientations between nursing and non-nursing students in female students of S.N.U., 3) to investigate the difference of value between students of S.N.U. and students of American universities. The questionnaire which was translated from the scale of Allport-Vernon Lindzeg. Study of values was administered to female students of S.N.U. from July 25 to September 7, 1976 and the sample for the study consisted of 476, subjects: 207 of nursing students and 269 of non-nursing students. They were selected by means of random sampling method. The statistical analysis of the resulting data included calculation of mean. standard deviation, F-ratio, and t-test. The following conclusions were obtained and the result of this study. 1) Comparing the mean of each college of S.N.U. with the norm made by Allport-Vernon-Lindzey. Students of college of human science and music stood relatively high in aesthetic value and students of college of natural science stood high in theoretical and social value. 2) There were not significant differences of each value among four grades of nursing students of S.N.U. Generally the researcher could 'find that the aesthetic value was dominant among nursing students, and the economic value got the lowest score. But the statistical test turned out not significant. 3) The mean of religious and economic value of nursing students was higher than that of non-nursing students. It was significant. 4) The mean of social and political value of nursing students was lower than of non-nursing student. It was significant. 5) The mean of theoretical and aesthetic value if nursing students was lower than that of non-nursing students. But the test was not significant. 6) Comparing the means of female students of S.N.U. with the norms for American college females made by Allport-Vernon-Lindzey. Students of S.N.U. stood high in theoretical, esthetical, and political value. 7) Students of nursing of S.N.U. got higher score than graduate students of Yale university majoring nursing is esthetical, political, and economic value.

As a part of host factors of dental caries,salliva has been well known for its important role in relation to dental caries.The studies on its physical and chemical charaterisitics on development and progress of dental caries has been condected.Recently,various comparisons between saliva of caries-susceptable individuals and caries-free individuals has been done and the efforts to understand the machanisms of salivary intervention of development and progress of dental caries is actively in progress.In this study,15 children with rampant dental caries and 15 caries free children without any systemic diseases from the ages of 2 to 5 were chosen for the experiment and the whole saliva and parotid saliva from each individuals were collected and protein compared using polyacrylamide gel electophyoresis(PAGE). As results of this study,in parotid saliva,there was no difference in protein compositions between the rampant dental caries and caries free children.While electrophoresis was done with the whole saliva,protein with 120 KDa was found in children with rampant dental caries.However,this protein was not found or unclear,if any for the caries free group.(Exceptionally,clear protein band was present for one person.)Protein compositions of whole saliva rampant dental caries group was compared before and after the caries control and thick and clear protein bands of about 120 KDa were found in both cases.Protein compositions of caries free children and adults were indentical.Quantitative analysis of protein was done for the rampant dental caries group and the control group and no significant difference was found. Taken all together,protein with molecular weight of 120 KDa,found in rampant dental caries group,was still present when the treatment for the dental caries was done so it can be assumed that this protein has no interrelation with the presence of active carious lesions during saliva collecting.It can also be presumed that this specific salivary protein with the molecular weight of 120 KDa found in rampant dental caries group has effect on development and progress of dental caries.Identification on this protein with the molecular-weight of 120 KDa and the role of this protein against dental caries remain to be solved.
