Purpose. This study was designed to examine the effects of a bereavement intervention program on levels of depression and life satisfaction in middle aged widows in Korea. Methods. A quasi-experimental design with non-equivalent control-group pretest-posttest was used. The subjects (control group, n = 10; intervention group, n = 17) were bereaved less than 6 months in G City and J Province, Korea. The bereavement intervention program consisted of Dan-jeon breathing, self-help group activities and a health examination. The experimental group attended 10 sessions of a bereavement intervention program. The control group had a health examination without the intervention program. For both groups, the level of depression and life satisfaction levels were measured before and after the experiment. Results. The decrement of depression level in the experimental group was significantly greater than in the control group (p <.001). The increment in life satisfaction in the experimental group was significantly greater than in the control group (p <.001). Conclusion. The results suggested that the bereavement intervention program was effective in decreasing level of depression and in increasing the life satisfaction of widows. Accordingly, a bereavement intervention program can be applied as an intervention to help widows.

Purpose: The aim of this study was to evaluate the effect of sexual health program for men with rectal cancer resection based on sexual function, self-esteem, depression, and marital intimacy. Methods: Using a quasi-experiment design, the intervention group (n=32) participated in the sexual health program based on PLISSIT (Permission, Limited Information, Specific Suggestions, Intensive Therapy) model. They received the program three times between August 2014 and March 2015. The comparison group (n=30) received a general educational program for rectal cancer. Four survey questionnaires such as International Index of Erectile Function (IIEF), Self-Esteem Scale, Center for Epidemiologic Studies Depressing Scale (CES-D), Marital Intimacy were used to measure the four key variables. Results: After the sexual health program, the intervention group showed statistically positive effect for the sexual function (F=4.14, p=.046), self-esteem (F=16.71, p<.001), depression (F=12.56, p=.001), and marital intimacy (F=12.45, p=.001) than the comparison group. Conclusion: Sexual health program should be consistently provided for men with rectal cancer resection since the intervention group reported better self-esteem, less depression, more intimacy and better sexual functioning.

Vehicle structures are composed of many substructure connected to one another by various types of mechanical joints. In vehicle engineering it is important to study these connected structures under various dynamic forces for the evaluations of fatigue life and stress concentration exactly. It is difficult to obtain the accurate load history of specified positions because of the errors such as modeling, measurement and etc. In the beginning of design exact load data are actually necessary for the fatigue strength and life analysis to minimize the cost and time of designing. In this paper, the procedure of practical dynamic force determination is developed by the combination of the principal stresses of F. E. Analysis and experiment. Least square pseudo inverse matrix is adopted to obtain in inverse matrix of analyzed stresses matrix. The error minimization method utilizes the inaccurate measured error and the shifting error that the whole data is stiffed over real data. The least square criterion is adopted to avoid these non. Finally, to verify the proposed procedure, a bus is analyzed. This measurement and prediction technology can be extended to the structural modification of any geometric shape in complex structure.

Purpose: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. Methods: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. Results: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system ($x^2$=13.89, p<.001) were significant, while the differences in the perception of depression ($x^2$=.02, p=.891) and coping methods ($x^2$=.34, p=.558) were not statistically significant. Conclusion: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

Most structures of automobile are composed of many substructures connected to one another by various types of mechanical joints. In automotive engineering, it is important to study these connected structures under various dynamic farces for the evaluations of fatigue life and stress concentration exactly. It is rarely obtained the accurate load history of specified positions because of the errors such as modeling, measurement, and etc. In the beginning of design, exact load data are actually necessary for the fatigue strength and life analysis to minimize the cost and time of designing. In this paper, the procedure of practical dynamic load determination is developed by the combination of the principal stresses of F.E. analysis and experiment. Inverse problem and least square pseudo inverse matrix are adopted to obtain an inverse matrix of analyzed stresses matrix. Pseudo-Practical dynamic load was calculated for Lab. Test of sub-structure. GUI program(PLODAS) was developed for whole of above procedure. This proposed method could be extended to any geometric shape of structure.
