The purpose of this study was to investigate the effect of helplessness, depression, subjective health status, family support, and social support on health promoting behaviors of elderly people over 65 years old. The subjects of this study were 3 welfare centers in G city and C city, 3 senior citizen center and 225 elderly people in 2 geriatric hospital, and this study was analyzed with descriptive statistics, reliability, correlation, confirmatory factor analysis, fitness test, total effect, direct effect, and indirect effect. The direct effects of variables affecting health promoting behaviors were social support, depression, family support, subjective health status, and helplessness. These variables accounted for 66% of health promoting behaviors. Depression, helplessness had a significant indirect effect on family support and social support, and subjective health status had a significant indirect effect on social support, but didn't have a significant indirect effect on family support. In this paper, we propose a new approach to elderly's health promoting behaviors and it is recommended that an intervention program be developed and applied to on personal situation should be necessary for elder's depression, helplessness and subjective health status.

This study examined the relationship between professional self-concept, interpersonal relationship, coping, and clinical practice satisfaction of nursing college students. This was a descriptive study. The survey participants were 355 students in M city and I city. The data were collected from May 29 to June 16, 2017 and self-report questionnaires, including the Professional Self-concept Scale, Interpersonal Relationship Scale, Coping Scale, and Clinical Practice Satisfaction Scale. The data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression. Professional self-concept showed significant differences according to religion, income, and school records. Interpersonal relationships showed significant differences according to gender, income, and school records. Coping showed significant differences according to the school records. Professional self-concept had a statistically positive correlation with interpersonal relationship, clinical practice satisfaction, and approach coping. Stepwise multiple regression analysis showed that the predictor of professional self-concept was interpersonal relationships, approach coping, religion, school records, and avoidant coping, which accounted for 45.2% of the variance. These results highlight the need for enhancement programs of nursing college students' professional self-concept that consider their interpersonal relationships, coping, religion, and school records.

This study was undertaken to identify knowledge, attitude, perception and nursing practice toward use of physical restraints, among nurses in long-term care hospitals. We further explored the impact of factors associated with nursing practice toward use of physical restraints. This was a cross-sectional descriptive study in which self-administered questionnaires were collected from 128 nurses working at 11 long-term care hospitals. Descriptive statistics, including t-test, one-way ANOVA, Welch's test, Pearson correlation coefficients and multiple regression, were applied to analyze the data collected. Our results reveal that the participants possess moderate levels of knowledge, attitude, perception and nursing practice toward use of physical restraints. Significant positive correlations were observed between nursing practice and knowledge. Multiple regression analysis showed that the factors significantly related to nursing practice and use of physical restraint were knowledge (${\beta}=0.27$, p=0.002) and attitude (${\beta}=-0.17$, p=0.044), having a total explained variance of 9.0%. The findings from this study suggest that knowledge is the strongest predictor on nursing practice toward use of physical restraints. Thus, we propose that developing and applying evidence-based educational intervention programs to reduce the use of physical restraints in long-term care hospitals are required.

This study examined the emotional intelligence and social support in relation to resilience in order to identify the factors influencing resilience in student nurses. The participants were 228 student nurses from two colleges in B City. The data were analyzed using a t-test, ANOVA, Pearson correlation coefficient, Scheffe test and multiple regression analysis by SPSS ver. 21.0. The mean score for emotional intelligence, social support, and resilience level was 5.36 out of 7 points, 4.13 out of 5 point, and 2.68 out of 4 points, respectively. Resilience was positively correlated with emotional intelligence (r=.665, p<.001) and social support (r=.495, p<.001). The results of this research suggest that social support is an important variable affecting resilience in student nurses. The factors affecting resilience were social support (${\beta}=.464$, p<.001), emotional intelligence (${\beta}=.169$, p=.004), and aptitude (${\beta}=.162$, p=.006). Resilience explained 50.4% of the variance in social support, emotional support, and aptitude. To increase the resilience of student nurses, managers need to develop resilience programs and training for managing social support, emotional intelligence, and aptitude.

The purpose of the present study was to investigate perceptions of mental health literacy and mental health services of local public officials in Korea. The participants were 273 civil servants working in three Gangwondo provinces. Data were collected from July 1, 2018 to August 15, 2018 using structured questionnaires, and SPSS Ver. 22.0 was used for data analysis. Results showed mental health literacy of public officials was 101.45 points (range 35-160). Mental health literacy level was found to be significantly dependent on occupation and levels of mental health education, mental health treatment experience, and family mental health treatment experience. Only 39.9% of respondents stated they were aware of mental health welfare centers. The most common condition that caused respondents to seek mental health services was depression (35.9%). In addition, 44.7% of the respondents opined that mental health care was improving due to community changes. An analysis of the relationship between perceptions of mental health welfare centers and mental health literacy scores showed a positive relationship between participant prior knowledge about mental health welfare centers and investment in mental health management (p=.012), suggesting a need for further development of educational programs using mental health nurses to improve mental health literacy among community officials.

In this study, it is describe to an optimization analysis process for the weight reduction of the voltage converter in the electric vehicle charging systems. The optimization design is a technique that finds the optimal material distribution under a given material quantity constraint by combining the design sensitivity with the material properties and the mathematical optimization. Among the topology optimization, a lightweight design is performed by a solid isotropic material with penalization with simple formula and well-convergence. The lightweight design consists of three steps. As a first step, a finite element model for the basic design of the on-board voltage converter was constructed and static analysis was performed on the load. In the second step, the optimum shape is obtained for the lightweight by performing the topology optimization using the solid isotropic material with penalization applying the stiffness coefficient of the isotropic material to the static analysis result. As a final step, impact analysis was performed by applying a half-sinusoidal pulse shape impact load which satisfies the impact test standard of the vehicle-mounted part with respect to the optimum shape. In the topology optimization, the design domain was defined as the mounting bracket area, and the design technology was finally achieved by optimizing the mounting bracket to achieve a weight reduction of 20% over the basic design.

The purpose of this study was to investigate whether a songwriting intervention would improve self-expression of adolescents with cochlear implants (CI). In this study, the songwriting intervention was designed to incorporate previous research findings on music perception of individuals with CIs and to provide musical experiences in which adolescents with CIs could be successful in using music resources for their self-expression. Accordingly, stepwise songwriting procedures were constructed and music technology (i.e., GarageBand as an iPad application) was used. Two adolescents with CIs participated in the intervention once a week for 8 weeks. Changes in level of participation in songwriting tasks, verbal expression, self-reports about the songwriting process were examined. The results demonstrated that the participants showed increased attempts to express themselves via music making. It was also shown that their negative perception of their ability to verbally express themselves decreased. They were observed as becoming more competent in creating music by deciding how various musical elements should be played and making rhythm or melodic patterns by themselves. These results indicate that the songwriting intervention can facilitate self-expression of adolescents with CIs. Further implications in terms of the psychosocial needs of individuals with CIs are presented.
