This study was examined to confirm the effect of emotional labor and social support on Job embeddedness in clinical nurses. The subjects were working in general hospitals over 300 beds in Gwangju area. The 197 data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and hierarchical regression analysis. Deep acting(r=.290, p<.01) of emotional labor and supervisor support(r=.389, p<.01) and peer support (r=.160, p<.05) of social support were reported positively correlated with job embeddedness. Deep acting(${\beta}=.236$, p<.001) of emotional labor and supervisor support(${\beta}=.319$, p<.001) of social support were reported to have effect on job embeddedness. These findings suggest that in order to promote job embeddedness of clinical nurses, the strategies to improve deep acting of emotional labor and supervisor support of social support should be provided in clinical nursing field.

Objective: This study examined the influence of child-care teachers' depression and social support on their burn-out and investigated whether social support had any moderating effects on the relationship between of child-care teachers' depression and burn-out. Methods: The participants of this study were 343 child-care teachers from 131 daycare center in Seoul and Gyeon-gi province. Statistical analyses of data for this study included descriptive statistics and hierarchical regressions. The moderating effect of social support was analyzed by using the procedures proposed by Baron and Kenny (1986). Results: The results of this study indicate that the level of child-care teachers' depression increases the level of burn-out and that the level of social support in workplace and the level of social support from out of workplace decreases the level of burn-out. In addition, social support from out of workplace only moderated the influence of child-care teachers' depression on their burn-out. Conclusion/Implications: The influence of child-care teachers' depression on burn-out was lower when the level of social support from out of workplace was high, compared to when it was low.

The purpose of this study is to analyze the characteristics of bearing capacity of pre-bored super strength PHC (SSPHC) piles socketed in rocks based on dynamic load test results. Because the SSPHC piles have high compressive concrete strengths compared with those of regular high strength PHC piles, the allowable structural strengths of the SSPHC piles were increased. For optimal design of the super strength PHC piles, the geotechnical bearing capacity of the SSPHC piles should also increased to balance the increased allowable structural strength of the SSPHC piles. Current practices of pile installation apply the same amount of driving energy on both SSPHC and high strength PHC piles. As results of analyzing factors that influence bearing strength of SSPHC piles using dynamic load test, there was no relationship between SPT-N value at pile toe and end bearing capacity. But driving energy effects on end bearing capacity. In case of skin friction, driving energy had no effects. And reasonable method verifying design bearing strength is necessary because end bearing capacity is not considered sufficiently in restrike test results.

In this study, inverse analysis was performed on the bi-directional axial compressive load test conducted on drilled shafts. And the bearing capacities were analyzed by numerical analysis of various pile tip ground conditions of silt clay, silt sand, sand silt, sand gravel, weathered rock, and soft rock. The bearing capacities were analyzed using the P-S method, the Davisson method, and the allowable sttlement of 25.4 mm. The minimum allowable bearing capacities analyzed by three methods were found to be 19.64 MN ~ 24.96 MN. At this time, the base resistances were sharing a 2% ~ 12% of a head load, shaft resistance were shared 88% ~ 98% of the head load. The greater the strength of pile tip was found to increase the allowable bearing capacity. However, the difference between the maximum allowable bearing capacity and the minimum allowable bearing capacity was 5.32 MN, and the increase in the allowable bearing capacity was only 27% depending on the pile tip.

This study was to investigate the effect of career decision-making self-efficacy and social support of university students majoring dance on career preparation behavior. For the study, 300 students from universities in capital area were selected to measure their career decision-making self-efficacy, social support and career preparation behavior. Correlation analysis and multiple regression analysis have been conducted to analyze research question using SPSS Ver. 24.0. The conclusion from results and discussion are as follows. First, there were positive relationships between career decision-making self-efficacy and social support and career preparation behavior. Second, career decision-making self-efficacy influenced career preparation behavior. Third, appraisal support a sub-factors of social support effected on career preparation behavior but emotional support, material support and informational support did not effect on career preparation behavior. Forth, career decision-making self-efficacy effected more than social support on career preparation behavior. Shortly, this study explored that career decision-making self-efficacy influenced career preparation behavior.

This study examines the mediating effects of social support on the relationship between health status and depression of the elderly in Korea. Through stratified multi-state random sampling, 1409 individuals aged 65 and over who lived in Seoul and Chunchen, and who had their own children were selected. Social support was composed of three types: emotional support, instrumental and financial support, and included both support-received from and provided to children. The multiple regression model proposed by Kenny and Baron was used. As the results, first, the elderly get more depressed when having lower health status and lower social support. Second, there is a partial mediating effect of social support in association with health status and depression. Comparing by gender, instrumental support received from children, and emotional and instrumental support provided to children are mediators in the link between health status and depression in the case of male. In the case of female, emotional, instrumental and financial support received from children, and instrumental and financial support provided to children shows the mediating effects between health status and depression. The results suggest that social support both received from and provided to children reduces the negative impacts of health status on depression of the elderly in Korea.

In this paper, polymer composite membranes and ceramic composite membranes were prepared in order to compare differences in pervaporation performances relative to the support layers. PVDF was used for the polymer support layers, and $a-Al_2O_3$ was used for the ceramic support layers. For active layer was coated for PDMS, which is a rubbery polymer. The characterization of membranes were analysed by SEM, contact angle, and XPS. We studied performances relative to the composite membrane support layers in the ABE mixture solutions. The results of the pervaporation, the flux of the ceramic composite membrane was shown to be $250.87g/m^2h$, which was higher than that of polymer composite membranes, at $195.64g/m^2h$. However, it was determined that the separation factor of the polymer composite membranes was 31.98 which were higher than that of the ceramic composite membranes, at 20.66.

Recently, the number of out-of-school adolescents has been increasing, and problems associated with their careers have become an important issue. This study was conducted to identify the relationship between the career barriers and perceived social support type/support source and to examine whether a sense of alienation mediates the relationship between perceived social support and career barriers among out-of-school adolescents preparing for the qualification examination for their high school degree. To accomplish this, a survey of 207 students from the Youth Support Center for out-of-school adolescents-K-Dream-and Qualification Examination Institute located in five regions (Seoul, Busan, Jeju, Gangwon, and Jeonla province) was conducted. Correlation analysis, regression analysis and the Sobel test were used to verify the relationships between variables and mediation effects. The results showed a significant negative correlation between social support and career barriers and a significant positive correlation between alienation and career barriers. Carrier barriers and alienation were highly correlated with parent support and evaluation support. Moreover, a sense of alienation was found to fully mediate the relationship between parental support/teacher support and career barriers, as well as to partially mediate the relationship between peer support and career barriers. A sense of alienation was found to fully mediate the relationship between information support/evaluation support/emotional support/material support and career barriers. These findings imply that, in out-of-school adolescents, career barriers can be reduced through various kinds of social support provided by peers, parents and teachers as it decreases the sense of alienation.

The purpose of this study is to propose safety factors of pile bearing capacity based on the reliability analysis. Each prediction method involves various degrees of uncertainties. To account for these uncertainties in a systematic way, the ratios of the measured bearing capacity from pile load tests to the predicted bearing capacity are represented in the form of a probability density function. The safety factor for each design method is obtained so that the probability of pile foundation failure is less than 10-3. The Bayesian theorem is applied in a way that the distribution using static formulae is assumed to be the A-prior and the distribution using dynamic formulae or wave equation based methods is assumed to be the likelihood, and these two are combined to obtain the posterior which has the reduced uncertainty. The results of this study show that static formulae of the pile bearing capacity using the 5.p.7. N-value as well as dynamic formulae are highly unreliable and have to have the safety factor more than 7.4 : the wave equation analysis using PDA(Pile Driving Analyzer) system the most reliable with the safety factor close to 2.7. The safety factor could be reduced certain amount by adoption the Bayes methodology in pile design.
