The purpose of this study was to examine whether Reasons for Living play mediating roles in the links between stress and suicidal ideation, and Social Support moderate the effect of stress on Reasons for Living. In addition, the mediated moderation effect on the relationship between stress and suicidal ideation was examined. A total of 608 university students completed self-reporting questionnaire on stress, suicidal ideation, Reasons for Living and social support. The results indicated that Living on Suicidal mediated the relationship between stress and suicidal ideation, and social support moderated the links between stress and Living on Suicidal. Finally, the mediated moderation effect of social support the association between stress, Living on Suicidal, and suicidal ideation was found. These findings suggest that social support may function as a protective factor for university students' suicidal ideation.

We prepared hydrophilic porous supporters for the reinforced composite fuel cell membrane by radiation grafting of acrylonitrile (AN) and hydrophilic sodium allylsulfonate (SAS) into a porous polytetrafluoroethylene (PTFE) supporter. The physicochemical properties of the supporters prepared under various reaction conditions such as molar ratio of SAS/AN, monomer concentration, and irradiation dose were evaluated. FTIR was utilized to confirm the successful introduction of SAS/AN copolymer chains into the porous PTFE. The pores of the porous PTFE film were found to be decreased with an increase in the degree of grafting by using FE-SEM and gurley number. Furthermore, by analyzing the degree of grafting, contact angle, and TBO (toluidine blue O) uptake, the hydrophilicity of the prepared supporters was found to increase with an increase in the degree of grafting.

The purpose of this study were to factor analyze the 25-item Personal Resource Question-naire (PRQ)-Part II, a social support measure, and to establish construct validity for the instrument among adolescents by relationship found between perceived social support and the theoretically relevant variables of attachment, parent-child relationships, and coping, The sample was consisted of 451 college students, aged 18 to 24. According to the criteria used in this study a four-factor structure, which consisted of 15-items, resulting from a principal components analysis with an oblique rotation, best represented the multidimensionality of the PRQ-Part II of late adolescents in Korea. Evidence in support of construct validity for both the 15-item and 25-item PRQPart II was provided by statistically significant correlations found between the two scales and the theoretically relevant variable of attachment, parent-child relationships, and coping. With the findings of this study, the 15-item Korean version of the PRQ-Part II can be used in research and practice as a reliable and valid instrument measuring perceived social support for late adolescents in Korea.

Recently, an interest on how to moderate parenting stress of grandparents is rising according to rising depression of grandparents of grandparents and grandchildren family(GGF) because of parenting stress So, this study tried to analyze moderating effects by setting social support and stress coping behaviors as moderator variable in order to know how much parenting stress of grandparents would influence their depression. For this purpose, we selected 369 cases of grandparents who were being provided social welfare service and to 334 cases out of them, did multigroup analysis using hierarchical regression analysis and structural equation model under spss Vor. 19.0 program. Followings are the results. First, the more parenting stress was high, the more depression high. But when social support was high, parenting stress low. And the more parenting stress was high, faith dependence, negative emotional expression and passive evasion as stress coping behaviors also high while problem reestablishment low. Second, emotional support, information support, and material support as social support had moderating effects in which parenting stress influenced depression while appraisal support had not. Third, faith dependence and low passive evasion as stress coping behaviors had moderating effects in influence of parenting stress to depression while problem reestablishment has not. On the one hand, emotional expression was meaningless in explaining moderating effects in connection with parenting stress. Through these, we draw a social welfare practical implication that could lift moderating effect of social support and stress coping behavior in between parenting stress and depression of grandparents of grandparents and grandchildren Family.

The purpose of this study was to analyze the effect that the social support for social welfare workers who are the key personnel providing the service to children directly at local child care center would have on job satisfaction. For this study, the social welfare workers of local child care center in Jeollanam-do were surveyed. A total of 240 questionnaires which had been collected were used for analysis. This study analyzed the effect of social support on job satisfaction by defining the demographic characteristics of social welfare workers as the control variables. The results of the analysis showed that the social support had the greatest influence on job satisfaction. Such results suggest that the stronger social support for social welfare workers would increase the job satisfaction of social welfare workers. Based on the results of the analysis, the following recommendations are presented which can help increase social support for social welfare workers: First, it is necessary to standardize the works of social welfare workers at local child care center and provide them with specialized training and education. Second, additional points should be granted to excellent local child care centers. Third, a cooperation system needs to be established which links the networks of colleagues and local societies.

This research has focused on comparing the capacity predicted by the theoretical formula with the one measured by field load tests to examine characteristics of the bearing capacity of a helical pile. The helical pile is featured by a central shaft with one or more helical-shaped bearing plates. Being established by a small rotary attached to an excavator that applies toque, the helical piles can be readily constructed at narrow sites, especially in an urban area with relatively less noise than the others requiring driving and excavation. Although many cases of the helical pile constructions can be recently found, the bearing capacity of the pile has been limitedly studied. To this end, this contribution analyzes and presents comprehensive results of the ten field loading tests with an application of different parameters depending on joint condition and specification of the helical piles, and types of tests and grouting.

Estimation of vertical bearing capacity is critical in the design of bucket foundation used to support offshore structure. Empirical formula and closed form solutions for bucket foundations in uniform sand or clay profiles have been extensively studied. However, the vertical bearing capacity of bucket foundations in alternating layers of sand overlying clay is not well defined. We performed a series of two-dimensional axisymmetric finite element analyses on bucket foundations in sand overlying clay soil, using elasto-plastic soil model. The load transfer mechanism is investigated for various conditions. Performing the parametric study for the friction angles, undrained shear strengths, thickness of sand layer, and aspect ratios of foundation, we present the predictive charts for determining the vertical bearing capacities of bucket foundations in sand overlying clay layer. In addition, after comparing with the finite element analysis results, it is found that linear interpolation between the design charts give acceptable values in these ranges of parameters.

The purpose of this study was to investigate the relationship between job stress, coworker support, emotional stability and burnout, and to examine the mediating effect of coworker support and emotional stability. A total of 212 noncommissioned officers were interviewed and correlation and mediating effect analysis were applied to the resulting data. As a result, the job stress showed a positive correlation with coworker support, emotional stability and negative correlation with burnout, and coworker support and emotional stability showed a negative correlation with burnout. In addition, coworker support and emotional stability were partially mediated by job stress and burnout. However, in order to examine the relationship between these two, the double mediation between job stress and burnout showed that the emotional stability of job stress was partially mediated directly by burnout, and that coworker support was mediated by burnout only through emotional stability. Based on these results, the implications and limitations of this study were discussed.
