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 use of drugs by pregnant women poses a potential risk to the fetus. Therefore, it is essential to classify drugs that pregnant women should prohibit. However, the fetal toxicity of most drugs has not been identified. This takes a lot of time and cost. In silico approaches, such as virtual screening, can identify compounds that may present a high risk to the fetus for a wide range of compounds at the low cost and time. We collected class information of each drug from the hazard classification lists for prescribing drugs in pregnancy by the government of Korea and Australia. Using the structural and chemical features of each drug, various machine learning models were constructed to predict fetal toxicity of drugs. For all models, the quantitative performance evaluation was performed. Based on the attention algorithm, important molecular substructures of compounds were identified in the process of predicting the fetal toxicity of the drug by the proposed model. From the results, we confirmed that drugs with a high risk of fetal toxicity can be predicted for a wide range of compounds by machine learning. This study can be used as a pre-screening tool for fetal toxicity predictions, as it provides key molecular substructures associated with the fetal toxicity of compounds.

The purpose of this study is to closely examine causality on the married-working women's depression. For this, the analytical materials were used the primary Seoul Metropolis Welfare Panel survey data. 507 married-working women in their 20s~50s were selected among survey subjects of Seoul Metropolis Welfare Panel data. The analytical method was used the structural equation model. As a result of analysis, it could be known that the path of perfect mediating effect in depression was formed after passing through the benefits satisfaction and the marital happiness from gender role attitude in the married-working women and that the benefits satisfaction has the partial mediating effect between depression and marital happiness. Suggesting a plan for getting rid of depression in the married-working women based on the results of this study, first of all, the married-working women's depression is greatly accredited to what our society regards domestic work yet as woman's role. Thus, the policy-based measure is demanded that can support for working women to be possibly compatible in work and family life and that can induce men's participation in household affairs and child-rearing in such context. Second, it was indicated that the more the married-working women adhere strictly to the gender role attitude of traditionalism, the lower result the marital happiness and benefits satisfaction have. Considering this, a plan for activating welfare system and family-friendly system is demanded that can change gender role value in traditionalism, which is being left in our society. Third, to promote marital happiness that has great influence upon the married-working women's depression, there is a need of seeking a plan, which further intensifies the family services including the marital education and the parent education.

The purpose of this study is to reveal the similarity and difference by comparing the quality of life between senior citizen group and disabled people group. For this purpose, I surveyed the questionnaire composed of sociological variable of population, social support, society activity participation, activity of daily living, self-efficacy, and quality of life to 113 senior citizens and 107 disabled people and analyzed the actual proof relationship of cause and effect in between variables. I executed the analysis of structural equation model by using SPSS 14.0 and AMOS 7.0 for the analysis of data. As the result of the study, firstly, the variables highly co-related with the quality of life to both senior citizen group and disabled people group were self-efficacy and society activity participation, and the variables highly co-related with self-efficacy were the quality of life and society activity participation. Secondly, the variables which show the meaningful difference between senior citizen group and disabled people group were society activity participation and activity of daily living. Thirdly, in the senior citizen group, social support, society activity participation, and activity of daily living have meaningful effect on self-efficacy, and all variables have meaningful effect on the quality of life. However, in the disabled people group, social support did not have meaningful effect on self-efficacy, and the social support and self-efficacy did not have meaningful effect on the quality of life. Based upon these study results I discussed the meaning and implications of the study, and suggested the successive study tasks.

The purpose of this study was to examine the mechanism through which youth school-based mentoring program impacts mentees' psychological and school-related outcomes such as self-esteem, self-efficacy, and attitudes toward school. The hypothetical model was assumed that mentors could improve their mentees' developmental outcomes through positive relationships with mentors as good role models and enhancement of help-seeking orientation. To investigate the mediating effect of process-related outcomes, structural equation modeling was used. The 97 adolescents were recruited through referral and random selection from middle schools in Seoul. The result showed that the effects of program participation were mediated by proximal changes in connectedness to role models and development of help-seeking orientation that, in turn, led to facilitate more positive attitudes toward school and academic activity, and improve psychological outcomes. Practice and policy implications as well as further research topics were discussed to aid the search for highly effective mentoring programs.

This study examined the effects of elderly care facility social workers' work environment (role conflict, role ambiguity, role overload, and adequacy of the reward system) and personal tendency (emotional empathy, cognitive empathy, external attribution, and internal attribution) on their burnout (emotional burnout, low personal achievement, and depersonalization about clients) and suggested strategies for preventing burnout in social workers at elderly care facilities. For this purpose, we conducted a questionnaire survey of social workers working at institutions designated as elderly long-term care facilities and collected a total of 312 questionnaires. According to the results of analyzing the data using a structural equation model, among the sub-factors of work environment, role ambiguity had a significant positive effect on low personal achievement and depersonalization about clients, role conflict on emotional burnout, and role overload on depersonalization about clients. Among the sub-factors of personal tendency, cognitive empathy and internal attribution had a significant negative effect on low personal achievement, and external attribution had a significant positive effect on emotional burnout and depersonalization about clients. This study is meaningful in that it illuminated social workers' burnout not only from the aspect of work environment but also from that of personal tendency.

This study explores gender mechanism of welfare politics in Korea from the perspective of welfare status theory. In the simplistic analysis, it is found that there is no gender difference in welfare attitudes. In the more sophisticated analysis of welfare-status-beased SEM, however, it is found that Korean welfare politics is to be understood in terms of gender-related politics. Three major findings of this study are as follows. Firstly, Korean women possess less pro-welfare attitudes in terms of the status of welfare beneficiary. This is due to the visible gender segregation in the Korean labor market on the one hand and due to the centrality of social insurance programs in the structure of Korean public welfare system on the other hand. Secondly, Korean women have relatively higher level of pro-welfare attitude when it comes to the status of welfare service provider. Thirdly, Korean women tend to be more supportive to pro-welfare parties as they have less chance to be a higher taxpayer. Based on the above mentioned findings, this study concludes that it is possible to make Korean women be more pro-welfare if the Korean welfare state expands more social services that tend to meet urgent needs of women.

To improve the seismic performance of suspended ceiling structures, various vibration-damping devices have been developed. However, the devices made of metals have a limit in that they cause large deformation and seriously damages the exterior of the suspended ceiling structure from the wall. As a results, their strengthening effect of the suspended ceiling structure was minimal. Thus, this study employed a spring and vibration-proof rubber effectively controlled vibrations without increasing horizontal seismic loads on the ceiling to enhance the seismic resistance of suspended ceiling structures. The objective of the study is to examine the dynamic properties of a seismic damping-isolation unit (SDI) with various details developed. The developed SDI was composed of a spring, embossed rubbers, and prestressed bolts, which were the main factors enhancing the damping effect. The shaking table tests were performed on eight SDI specimens produced with the number of layers of embossed rubber (n_s), presence or absence of a spring, prestressed force magnitude introduced in bolts (f_ps), and mass weight (W_m) as the main parameters. To identify the enhancement effect of the SDI, the dynamic properties of the control specimen with a conventional hanger bolt were compared to those of the SDI specimens. The SDI specimens were effective in reducing the maximum acceleration (A_{c max}), acceleration amplification factor (α_p), relative displacement (δ_R), and increasing the damping ratio (ξ) when compared to the control specimen. The A_{c max}, α_p, and δ_R of the SDI specimens with two rubbers, spring, and f_ps of 0.1f_by, where f_by is the yielding strength of the screw bolt were 57.8%, 58.0%, and 61.9% lower than those of the conventional hanger bolt specimens, respectively, resulting in the highest ξ (=0.127). In addition, the α_p of the SDI specimens was 50.8% lower than those specified in ASCE 7 and FEMA 356. Consequently, to accurately estimate the α_p of the SDI specimens, a simple model was proposed based on the functions of f_ps, stiffness constant of the spring (K), W_m, and n_s.

The purpose of this study is to identify the organizational characteristics that enhance CRM performances of a company. Based on a review of diverse definitions of CRM performance, this study examines the relationships among CRM performance measures and organizational characteristics. A questionnaire survey of 123 CRM managers of Korean companies was conducted to test the proposed research model, and a series of structural equation modeling identified the strong effects of organizational characteristics on CRM performance. It was found that top management commitment to CRM and a firm's strategic readiness lead to high levels of CRM investment, which, in turn, enhance directly task-related performance and indirectly customer-related performance. This study also confirmed that customer orientation is significantly related to task-related CRM performance and that the variables of CRM commitment and organizational culture may enhance customerrelated performance indirectly through their effects on the task-related performance. However, organizational members' resistance to change was found to have no effects on CRM performance. Overall our research broadly supports the role of organizational characteristics revealed in the CRM literature.

This research investigates the effect of brand-self identification on brand attachment and brand commitment focusing on luxury brand. Another purpose of this study is to examine how the relationships among brand identification, brand attachment and brand committment are moderated by consumers' regulatory focus. Structural Equation Modeling using 214 questionnaires was conducted to test hypothesized model. The results reveal that perceived luxury brand personality including excitement, competence, and sophistication influences brand-self identification positively, which in turn has a signifiant positive effect on the brand attachment. It is also found that consumers' emotional attachment to luxury brands has a positive influence on the luxury brand commitment while the effect of the brand-self identification on the brand commitment is not signifiant. This finding strongly supports that brand attachment and brand commitment are distinct construct, which confirms the results of the previous studies. In addition, the results show that consumers-luxury brands relationships are moderated by consumers' regulatory focus. This finding explains that prevention-focused individuals who have interdependent self-view respond to the loss caused by relationship break more sensitively compared to the promotion-focused consumers. Finally, based on the findings of this study, theoretical contribution and managerial implications are discussed.
