This study explored the relationships between Husband's emotional support and the mother's postpartum depression. The purpose of this study was to contribute to theoretical understanding of the relationships among these two variables and eventually to direct the planning of nursing care that enhance the health status of mothers in the postpartum period. Data were collected from January to June, 1995, with 47 postpartum Korean mothers in NewHampshire state in The United States of America. Postpartum depression was measured by Jung's Self-rating Depression Scale and husband's support was measured by Husband's support scale developed by Cho, Young Sook. Postpartum depression and husband's support were measured by postpartum mothers on the 3rd postpartum day and 2 weeks. The data were analysed by an SPSS computerized program and Percentages, t-test, paired t-test. ANOVA, Pearson correlation coefficients, and Stepwise multiple regression were used. The result of this study were summerized as follows ; 1. Mother's postpartum depression was greater at two weeks than the 3rd day (t=-2.64, p<.05). 2. Mother's percieved husband's supportive behavior was lower at 2 weeks than the 3rd day(t=-3.14,p<.01) 3. The higher the husband's supportive behavior, the lower the postpartum mother's depression (r=-2650,-2845;p<.01) 4. In this study, variables related to the mother's postpartum depression were husband's support, how much the husband liked the baby, occupation, and the knowledge of how to care for the baby. 5. In addition, by using Stepwise multiple regression analysis, it was determined that the main influencing factors on the postpartum depression. The variables - husband's support, how much the husband liked the baby and job made it possible to explain 48.61% of variance in postpartum depression.

Background: Most clinical studies of immune responses activated by Korean Red Ginseng (KRG) have been conducted exclusively in patients. However, there is still a lack of clinical research on immune-boosting benefits of KRG for healthy persons. This study aims to confirm how KRG boosts the immune system of healthy subjects. Methods: A total of 100 healthy adult subjects were randomly divided into two groups that took either a 2 g KRG tablet or a placebo per day for 8 weeks. The primary efficacy evaluation variables included changes in T cells, B cells, and white blood cells (WBCs) before and after eight weeks of KRG ingestion. Cytokines (TNF-α, INF-γ, IL-2 and IL-4), WBC differential count, and incidence of colds were measured in the secondary efficacy evaluation variables. Safety evaluation variables were used to identify changes in laboratory test results that incorporated adverse reactions, vital signs, hematological tests, blood chemistry tests, and urinalysis. Results: Compared to the placebo group, the KRG intake group showed a significant increase in the number of T cells (CD3) and its subtypes (CD4 and CD8), B cells, and the WBC count before and after eight weeks of the intake. There were no clinically significant adverse reactions or other notable results in the safety evaluation factors observed. Conclusion: This study has proven through its eight-week intake test and subsequent analysis that KRG boosts the immune system through an increase in T cells, B cells, and WBCs, and that it is safe according to the study's safety evaluation.

In order to reduce the number of installation processes and the cost, a unified ball valve and polyethylene-steel pipe is proposed and tested. An integrated design approach is carried out such that a virtual manufacturing based on finite-element analysis is first performed in order to examine contact conditions under exaggerated temperature variations (${\Delta}T\;=\;60^{\circ}C$ and $-50^{\circ}C$ for summer and winter, respectively). From the final design configuration, it was predicted that the maximum contact pressures are 71 and 8.1 MPa for summer and winter, respectively, at relatively larger contact surface. Based on this observation, a prototype model is fabricated to go through an actual leakage test. The prototype pipe passed a hydrostatic strength test successfully, showing no leakage at even much higher (54 MPa) than the operational pressure (0.25 MPa).

The purposes of this study were to examine if there is a relationship between elderly people's anxiety towards death and their reactions to the Star-Wave drawing, and to verify if the Star-Wave drawing was a good enough tool to measure elderly people's degree of death anxiety. The subject for this study were 307 elderly people (male 127, female 180) over 60 years of age with no physical and cognitive damage, who were residing in Geongsan city and attending colleges or welfare centers for the aged. The collected data were analyzed with SPSS WIN(ver. 12.0) program, and factor analysis, correlation analysis, Chi-square test, t-test, one-way ANOVA, and $Scheff\acute{e}$ test were utilized. The results showed that factors showing different levels of anxiety towards death in the Star-Wave drawing were the total harmony of the drawing, drawing style, repetition of wave, size of the star, and location of the star. In particular, the group that drew the Star-Wave drawing with total harmony felt less anxiety towards death than the other group. Therefore, the results of this study suggested a possibility of the Star-Wave drawing to be used as a good tool that could diagnose the elderly's degree of anxiety towards death.
