1 . Experimental study Preventive effect of Korea Red Ginseng (KPG) on hypertensive retinal arteriolosis in rabbits was studied. The results as follows: Blood pressure: Hypertensive group (B) was obviously raised up in comparing with that in normal group(A) and in hypertension + KRG group(C). Ocular fundus:Changes in B group including the retinal arteriospasm, crossing arterioveous, exudation and edema. But C group showed lightly. Light microscope: HE stained vascular damage in retina including thickness hyalimisation, execdates and edema Electron microscope: The endothelial cells were arranged irregularly, different shape and showed cytoplasm loose and vacuole. Immunohistochemistry: Ginseng can regulating endothelin-1, angiotension-ll, endothelium grow factor expre,j,iion and secreation in retinal blood clrultion. 2. ClinicAl Study 66 of hypertensive patients (42 men, 23 women,48-68 years old)and 20 normal person (7 men, 13 women,47-68 years old) were administrated(p.0.) by HRG (3g per day for 6 weeks). The results showed that marked effective rate and total effective rate were 53cyo and 60.6alo respectively and no severe side effects were found. The above results suggest that Ginseng have a difinite hypotensive effect and a role of preventing hyperfine sloe arteriosclerosis.

The purpose of this research was to study differences between reciprocal and unidirectional friendships and to examine evidence on whether certain constituents of friendship can predict the termination of friendships. A total 375 subjects- 190 elementary and 185 middle school children in Pusan- were administered questionnaires two times at an interval of 3 months. Frequency, factor-analysis, t-test, discriminant-analysis, and cross classification analysis were applied for data analysis. The results of the study were as follows: 1) The different constituents of reciprocal and unidirectional friendships were statistically significant. That is, children in reciprocal friendships perceived their relationships more positively, felt closeness more strongly, and evaluated their friend more highly than the children in unidirectional friendships. 2) The termination of reciprocal friendships was predicted by the constituents of friendship. The most powerful predictor was the degree of closeness and the second powerful predictor was the degree of commitment to the relationship and the 3rd powerful predictor was perceived characteristics of the friend. The last powerful predictor was perceived characteristics of the relations. 3) There were no sex differences in the rate of termination of reciprocal relationships. 4) There were age differences in the rate of friendship termination of reciprocal relationships. That is, the rate of termination of reciprocal relationships among older children was higher than among younger children.

Purpose: Gastric cancer is a highly metastatic malignant tumor, often characterized by chemoresistance and high mortality. In the present study, we aimed to investigate the role of B-cell lymphoma 3 (Bcl-3) protein on cell migration and chemosensitivity of gastric cancer. Materials and Methods: The gastric cancer cell lines, AGS and NCI-N87, were used for the in vitro studies and the in vivo studies were performed using BALB/c nude mice. Western blotting, wound healing assay, Cell Counting Kit-8 assay, immunohistochemistry, and terminal deoxynucleotidyl transferase dUTP nick end labeling assay were used to evaluate the role of Bcl-3 in gastric cancer. Results: We found that the protein expression of hypoxia (HYP)-inducible factor-1α and Bcl-3 were markedly upregulated under hypoxic conditions in both AGS and NCI-N87 cells in a time-dependent manner. Interestingly, small interfering RNA-mediated knockdown of Bcl-3 expression affected the migration and chemosensitivity of the gastric cancer cells. AGS and NCI-N87 cells transfected with si-RNA-Bcl-3 (si-Bcl-3) showed significantly reduced migratory ability and increased chemosensitivity to oxaliplatin, 5-fluorouracil, and irinotecan. In addition, si-Bcl-3 restored the autophagy induced by HYP. Further, the protective role of si-Bcl-3 on the gastric cancer cells could be reversed by the autophagy inducer, rapamycin. Importantly, the in vivo xenograft tumor experiments showed similar results. Conclusions: Our present study reveals that Bcl-3 knockdown inhibits cell migration and chemoresistance of gastric cancer cells through restoring HYP-induced autophagy.

This study examined relationships between peer variables and externalizing behavior problems of 290 4th and 5th grade children in elementary school. The children completed the Friendship Quality Scale and the peer nomination questionnaire. Parents and teachers rated behavior problems of children using the Connors' Rating Scale. Results indicated that rejected children had more behavior problems than popular, average, or neglected children. Socio-emotional supports from a close friend and satisfaction with the friend were negatively related to behavior problems. Behavior problems were mainly predicted by low peer acceptance, and behavior problems of rejected children were negatively and strongly related to socio-emotional supports of a close friend. In conclusion, peer rejection was a risk factor and a friend's support was a protective factor for externalizing behavior problems in 4th and 5th graders.

Purpose: This study was conducted to identify ethical climate factors in hospitals and analyze their influence on job satisfaction and organizational commitment. Methods: A convenience sample of 196 nurses from one national university hospital in J city participated in this descriptive study survey. Instruments included the Ethical Climate Questionnaire, Job Satisfaction Scale, and Organizational Commitment Scale. Cronbach's ${\alpha}$ and factor analysis were done to test reliability and construct validity of the scales. Data were collected from March 15 to March 25, 2013 and analyzed using descriptive statistics, one-way ANOVA, t-test, Pearson correlation, and multiple regression with SPSS/WIN 18.0. Results: Seven ethical climate factors were identified; laws and professional codes, social responsibility, company rules and procedures, self-interest, personal morality, efficiency, and friendship. Factors influencing job satisfaction were friendship (${\beta}$=.25), social responsibility (${\beta}$=.20), laws and professional codes (${\beta}$=.20), and educational level (${\beta}$=.27), explaining 37.6% of variance in job satisfaction. Factors influencing organizational commitment included social responsibility (${\beta}$=.29), friendship (${\beta}$=.27), laws and professional codes (${\beta}$=.23), and age (${\beta}$=.19), with explanatory power of 44.6%. Conclusion: Results can be used as preliminary data for developing new strategies to establish positive ethical climates in hospital environments and thus enhance nurses' job satisfaction and organizational commitment.
