The purpose of this research was to investigate the relation between social support and the knowledge of drug which affects drug abuse in elderly by using structure equation model(SEM). The samples included 177 elderly who lived in 'D' city was selected. Data were collected and analyzed using questionnaires for 13 days from May 13 to May 25, 2013. 3 factors of research models had a significant model fit and correlation. The key research findings are as follows. First, the more social support they have, the more knowledge of drug they tend to have(${\beta}$=.515, p=.005). Second, direct effect that social support led to drug abuse was significant.(${\beta}$=-.769, p=.002) However the indirect effect was not significant(${\beta}$=.036, p=.671). Third, the indirect effect that social support led to drug abuse was not significant, which means it has no mediating effect. Social support turned out to be very important factor in this research, but other preceding research mentioned that knowledge of drug is an important factor which could reduce drug abuse. Research needs to be analyzed repeatedly for verification of effects.

Cracks in RC members occurred as a result of material and structural factors. The crack width and a crack location are very difficult to examine. A direct crack control method and indirect crack control method to control a crack are presented in the KHBDC (LSD) and KSCDC (2012). In the KSCDC text, cracks are controlled by steel spacing indirectly under a service load. On the other hand, in the KSCDC appendix, cracks are controlled by a crack width directly under a sustained load. In particular, the loading state considered is different. On the other hand, cracks are controlled under a combination of service load and an effective elastic modulus is used in KHBDC. Therefore, in this study, an effective elastic modulus that can reflect the ratio of the sustained load and live load was applied, and a maximum steel spacing was calculated through a design crack width. A variable interpretation was carried out, and a rational crack control method was assessed. As a result, a steel spacing through the design crack width in the KSCDC was smaller than that from the design crack width in the KHBDC, which leads to a conservative design. In addition, the maximum steel spacing suggested in this study has a consistency eliminating the difference between direct crack control and indirect crack control.

This study was conducted to investigate the relationship among major satisfaction (MS), clinical competence (CC), career decision-making self-efficacy (CDMS), and career decision level (CDL) for undergraduate nursing students. A self-report instrument was used to measure MS, CC, CDMS, and CDL. Questionnaires were completed by 307 nursing students in three nursing colleges, and path analysis was employed to validate the proposed model and analyze the causal relationships among variables. Four constructs (MS, CC, CDMS, and career decision) were analyzed. To build a path model, MS and CC were linked to CDMS and career decision. The initial analysis suggested that the modification needed modification; therefore, a covariance link was added. The overall goodness of fit for indices indicated satisfactory path analysis. The indices were revealed as $x^2=2412$, GFI=0.996, AGFI=0.961, and RMSEA=0.068. As a result, the proposed model was acceptable with a good fit, and there were significant direct and indirect effects of paths in the model. Specifically, MS and CC had a direct influence on CDMS, and MS and CDMS directly affected CDL. Moreover, MS and CC had indirect effects on CDL through CDMS. These results imply that students' CDMS should be seriously considered when designing counseling programs for career guidance, and substantiality of CC education is needed to improve CDMS. These results may provide a practical guideline to provide educational intervention for nursing students.

This cross-sectional correlational study investigated factors affecting career planning of nursing students, focusing on the associations between satisfaction of academic major, perceived professional competence, and job expectations. Data from 255 nursing students were collected through self-administered questionnaire surveys on 2016 January 4 and 7 and analyzed using descriptive statistics, Pearson's correlation coefficients, t-tests, bootstrapping SPSS macro and path analysis using AMOS. There were significant correlations between major satisfaction, professional competence, and job expectations. Both major satisfaction and professional competence were significant factors influencing job expectations, but their effects on job expectations were significantly different depending on whether there was a role-model, which support a moderating effect of having a role-model. Major satisfaction had a significant direct effect on career planning, but its indirect effect on career planning through job expectations was not significant. Professional competence did not have a significant direct effect on career planning, but its indirect effect on career planning through job expectations was significant. Overall, the results highlight the importance of providing educational support and opportunities for nursing students to explore their own motivation and to have a role-model during pursuit of a nursing career.

This study analyzed the direct and indirect effects of job competency education on job goal setting, job preparation behavior and first job satisfaction from the perspective that successful employment requires improving the job ability needed for college students. Data on 5,044 students were analyzed based on the 2013GOMS of Graduates Occupational Mobility Survey(GOMS). The study findings are summarized as follows. First, job competency education not only acted positively on job goal setting but also contributed to promoting job preparation behavior. Second, job preparation behavior contributed to improving satisfaction with the first job. Third, indirect effects of job competency education and job goal setting in first job satisfaction. In conclusion, job competencies enhances the possibility that college students may obtain their wanted job by setting a clear goal for their job and having a positive effect on the required behavior. Accordingly, college student should try to reinforce their special capability to accomplish the given job as career professionals in consideration of their aptitude rather than devoting themselves to reinforcing their basic capability such as linguistic ability. For this purpose, both universities and the government should develop educational programs for college students to grasp their aptitude and cultivate their special ability to become career professionals and provide a foundation for them to become talented professionals armed with special capability by proving support for job ability improvement.

This study was conducted to determine the casual relationship among family support, social support, workplace spirituality, and quality of life (QOL) for middle-aged, male office workers, as well as the effects of family support, and social support on their QOL with the mediation of workplace spirituality. The participants were 288 middle-aged, male office workers, and the data were collected from 14 October to 30 November, 2016, through questionnaires. The data were analyzed with descriptive statistics and Pearson's correlations using PASW 21.0, while the AMOS 18.0 program was used for structural equation modeling (SEM), and the fitness of the final model was determined using RMSEA .05, GFI .98, AGFI .94 and NFI .96. The results of this study can be summarized as follows. There were correlations between family support, social support, workplace spirituality, and QOL for the middle-aged, male office workers. Second, family support (${\beta}=.60$, p<.001) and social support (${\beta}=.47$, p<.001) had a direct effect on their workplace spirituality. Third, family support had direct (${\beta}=.12$, p=.002) and indirect (${\beta}=.10$, p<.001), while social support also had direct (${\beta}=.12$, p<.001) and indirect (${\beta}=.08$, p<.001) effects on their QOL. The findings also suggested that workplace spirituality had a partial mediating effect between the family support, social support, and QOL of the middle-aged, male office workers.

The purpose of this study is to examine the difference in the mediating effects of relief from fatigue through sleep and perceived subjective health in the relationship between perceived stress and subjective happiness in middle school students who attempted suicide. The analysis was conducted using Path analysis, the Bootstrapping method, Phantom variable and Multiple group analysis by AMOSS using the IBM SPSS 23 and IBM SPSS AMOS 23 programs with 820 middle school students who attempted suicide in the past 12 months using the raw data of the Korea Risk Behavior Web-Based Survey (2016). In the relationship between perceived stress and perceived subjective health, the indirect effect of relief from fatigue through sleep and perceived subjective health (${\beta}=-.12$, p=.003) was statistically significant. The difference in the magnitude of the two indirect effects was found to be greater for the subjective health status than for relief from fatigue through sleep (difference = .02, p=.028) and the effects were greater for the males (${\beta}=.44$, p <.001) than for the females (${\beta}=.23$, p<.001). Based on the findings, it is necessary to develop and apply an educational program that includes the factors that contribute to improving the happiness of middle school students.

The study aims were to verify the influences of job environment factors and work attitude on turnover intention of school foodservice employees, and then to verify the mediating effect of organization commitment between six areas of worklife and turnover intention so that organizations can intervene to reduce the turnover intentions of employees. The subjects were 205 employees who were working in the school foodservice field. The job environment factors were measured by six areas of worklife (workload, control, reward, fairness, community, value) and the organizational commitment was measured by two types of commitments (affective, continuance). The results were as follows. First, workload, reward, community and value of six areas of worklife reduced affective commitment, control and fairness increased continuance commitment, and affective commitment reduced turnover intention. Second, only reward and community showed direct effect on turnover intention, but all six areas of worklife had a statistically significant indirect effect on turnover intention through affective commitment. These results showed that job environment factors had both direct and indirect effect on employees' behavior through employees' affection. These findings imply that organizations can control employees' turnover intention by providing education or social support to maintain their affective commitment even when organizations cannot change job environment.

Stress is closely associated with oral diseases, being considered to be one of important variables to affect the improvement of oral health and the quality of life. In this study, a survey was conducted on 550 adults from July 1, 2012, to February 28, 2013. A path analysis was carried out to determine the influence of physical stress symptoms and psycho-emotional stress symptoms on dry mouth, oral mucosal disease and halitosis symptoms. The findings of the study were as follows: Oral mucosa affected halitosis in a direct effect and dry mouth exerted a direct influence on that as well. When stress symptoms affected halitosis, dry mouth and oral mucosa had an indirect impact on that as parameters. Dry mouth exercised a direct influence on oral mucosa. The above-mentioned findings suggested that the physical stress symptoms and psycho-emotional stress symptoms of the adults affected their dry mouth, oral mucosal disease and halitosis both in direct and indirect effects. As the stress of adults is closely bound up with their oral diseases, how to properly cope with stress should carefully be considered in order for them to lead a better life.

This study tested the effects of stress on smartphone addiction via depression and self-efficacy among college students, and the analysis results were as follows: setting mediator and extra variables significantly correlated with the criterion variable as covariates and applying the regression analysis and SPSS Macro as well as bootstrapping method, to verify the mediating effects of depression and self-efficacy in stress and smartphone addiction. This study analyzed the direct effects of stress on the depression, self-efficacy, and smartphone addiction of college students and found that stress had direct effects on their depression and self-efficacy and also indirect effects on their smartphone addiction via depression and self-efficacy. Both depression and self-efficacy had dual and partial mediating effects on the influences of stress on their smartphone addiction. Stress had significant dual mediating effects on their smartphone addiction via the indirect paths of depression and self-efficacy, and high stress also had significant direct effects on their smartphone addiction, thus validating the dual mediation model. These findings demonstrate the need to develop programs to mitigate the stress and depression of college students and enhance their self-efficacy in order to reduce their smartphone addiction.
