The purpose of this study was to determine influential factors for health behavior of elderly people living alone in an urban area. The subjects were 203 selected senior citizens who were living alone in a city. The findings were as follows: The subjects got a mean of 2.89 in self-rated health status, which was lower than the medium score 3. They got a mean of 2.64 in self-efficacy; 3.87 in social support and 3.14 in health behavior. These scores were higher than the medium score. The factors that affected the health behavior of the elderly people were self-efficacy, social support, self-rated health status, economic state, religion and gender. These factors had a 43% explainability of the health behavior of the urban senior citizens living alone. The findings are expected to make a contribution to the development of health care programs geared toward urban elderly people living alone.

It would be much effective that single column type pier is used in concrete slab bridges rather than ${\Pi}$ or gravity type pire is used. To determine the longitudinal benging moment in concrete slab bridges supported by single column type piers, the concept of effective width is applied. By elastic plate theory cooperated with finite element method, the distribution of the longitudinal moment of the slab supported by single column type piers is studied. The main variables are span, width. thickness of the slab, and column section size. The analytical results obtained are summarized and analysed to evaluate the maximum longitudinal negative moment, then a simplified method for calculating the longitudinal moment is proposed.

During pregnancy, the woman experiences physical and psycho-social changes. Such changes and other factors may become stress for the pregnant woman, making it difficult to maintain healthy and happy pregnant period. In this study, we identify factors for the stress, marital intimacy, family support, and fatigue, in order to provide the foundation for developing intervention programs and improve the quality of nursing. The subjects of there search were 185 pregnant women. Stress had a negative correlation with marital intimacy and family support, and positive correlation with fatigue. Family support, fatigue, adjustment to change due to pregnant, and breastfeeding experience were the influencing factors on the stress of pregnant women. A stress management program for pregnant women needs to be designed to help them with their physical and psychological adjustments. The program will be more effective when accompanied by the family support.

The present study set out to explore the acculturative stress and mental health(depression) of Korean women living in Britain according to socio-demographic factors, social relations and social supports level. 152 Korean women's data were collected and analyzed with frequency, correlation, ANOVA. Analysis revealed that women's acculturative stress and depression level was 2.50(moderate) and 1.66(slightly low) respectively. Acculturative stress level showed correlation with depression level. Among demographic variables, acculturative stress was significantly different from residence period in Britain, marriage and economic state and the level of depression was also different from job and economic state. The group which has frequent relationships with British and high level of social supports showed low acculturative stress. The group has high level of social supports also showed low depression. These findings highlight the importance of concerns and interventions about acculturation and mental health of Korean immigrant women and community services for the new immigrant women to improve their acculturation and mental health.

The objective of this research was to provide an objective and scientific basis for the effect of mid-advertising on viewers' rights by conducting an empirical study on how mid-program advertising affects viewer satisfaction and interest from the viewers' perspective. The experiment was conducted on 210 subjects to investigate the difference between viewers' interest in the program and purchase intention price. The results did not support the hypothesis that advertisements inserted in the middle of television programs would affect the dependent variables. The theoretical and practical implications of the mid-program advertisements on the interests of viewers were discussed.

The system such as railway bridge can be modelled as the restrained beam with intermediate supports. This kind of structures are subject to the moving load, which has a great effect on dynamic stresses and can cause sever motions, especially at high velocities. Therefore, to analyze the dynamic characteristics of the system due to the moving load is very important. In this paper, the governing equation of motion of a restrained beam subjected to the moving load is derived by using the Hamilton's principle. The orthogonal polynomial functions, which are trial functions and satisfying the geometric and dynamic boundary conditions, are obtained through simple procedure. The dynamic response of the system subjected to the moving loads is obtained by using the Galerkin's method and the numerical time integration technique. The numerical tests for various constraint, velocity and boundary conditions were preformed. Furthermore, the effects of mass of the moving load are studied in detail.

The purpose of this study was to investigate the degrees of and relationships between self-esteem, social support, and state anxiety in community-dwelling unmarried mother raising a child. Descriptive correlational study design was used. Data were collected from 65 participants with self-report questionnaires from May to December, 2011. First, the mean of self-esteem was 3.52, social support 3.49, and state anxiety 2.47 respectively. Second, the correlation between self-esteem and social support was also statistically significant(r=.286, p=.021), the correlation between self-esteem and state anxiety was statistically significant(r=-.780, p=<.001), and the correlation between social support and state anxiety was also statistically significant(r=-.425, p=<.001). Self-esteem for unmarried mother raising a child in the study was confirmed as the primary important concept. Also, the correlation between social support and state anxiety was verified as significant. Therefore, study is needed to develop a nursing intervention program for self-esteem and social support improvement, and state anxiety decrease of unmarried mother raising a child.

The natural frequencies of a beam on elastic foundation are investigated in the present paper. The inhomogeneous elastic foundation can be modelled as a combination of distributed translational spring, rotational spring, intermediate supports and dampers. The natural frequencies and mode shapes of the system are obtained by using the Galerkin's method, and also compared with the results in the literature. Furthermore, the natural frequencies of the beam with elastically mounted masses, which can be used as vibration absorbers, are obtained by an efficient numerical scheme suggested in the present paper.

This paper describes the natural frequencies obtained through FEA (Finite Element Analysis) and Numerical Analysis which uses the boundary conditions to each equation of motion and the consecutive conditions at each supporting point. And then. we studied on the optimal position determination of middle supporting points to maximize the natural frequency of a beam at 24 Models. We present the data of optimal condition for designing a beam.

The purpose of this study was to examine the moderating and mediating effects of social support and social activity on the relationship between depression and quality of life in elderly women living alone. Subjects were 129 elderly living alone at K city in C province, from June to July, 2010. The data was analyzed using the SPSS program for descriptive statistics, Pearson's correlation coefficient and stepwise multiple regression. The degree of depression of elderly living alone was above the average(2.65), and that of quality of life was average(2.80). The correlated factors of quality of life among elderly women living alone included depression(r=-.745, p=.004), social support(r=.544, p=.000), leisure activity(r=.480, p=.024), and economic activity(r=.711, p=.001). Social support was an important mediator between the depression and quality of life in elderly women living alone. The moderating effects of social support and social activity between depression and quality of life in elderly women living alone were not significant. This study suggests that social support considered in enhancing the quality of life programs designed for elderly living alone. Further research needs to be done to refine moderating and mediating effects of social support, social activity including leisure activity, economic activity and volunteer activity.
