The purpose of this study is to investigate the effect of job stress and social support on the organizational effectiveness of hospital employees and to examine the role of social support in the experience of job stress among the employees. Previous studies have yielded mixed results regarding the role of social support. Some studies provide supporting evidence for the buffering effect of social support, while others do not. Still others report findings about reverse buffering effects. These inconsistent findings are, in part, accounted for by methodological problems such as poor measurement, small sample size, and the existence of high multicollinearity. To examine more rigorously the role of social support in relation to the negative effects of job stress, this study was carefully designed to overcome methodolgical shortcomings found in the past research. In addition, unlike the previous studies, which were concerned mostly with health-related variables as consequences of job stress, in this study, three work-related variables (job satisfaction, organizational commitment, and intent to stay) which had close relationships with organizational effectiveness were examined as output variables. The sample used in this study consisted of 353 employees from a university hospital in the surburbs of Seoul. Data were collected with self-administered questionnaires and analyzed using canonical analysis and hierarchical regression analysis. The results of this study indicate that; (1) job stress has negative main effects on job satisfaction, organizational commitment, and intent to stay; (2) social support has positive main effects on the same three output variables, (3) social support does not moderate the harmful effects of job stress on the three outcome variables, and (4) the three-way interaction effects of (social support * job stress * gender) and of (social support * job stress * education) are not supported. The implications of these findings for the management of human resources are discussed.

This study was conducted in order to assess the effect of variables influencing Korean baby-boomers' welfare consciousness. For this purpose, data from the $8^{th}$ supplementary survey of the Korea Welfare Panel in 2013 were analyzed. The subjects of analysis were 2,035 people who were born between 1955 and 1965 whose welfare panel data did not have missing values for the variables of the research model. According to the results of analysis, first, when the descriptive statistics of the major variables were analyzed, those showing a relatively high mean score among the sub-factors of the baby-boomers' welfare consciousness were 'expansion of expenditure for public assistance' (mean 3.65, SD .557), 'expansion of expenditure for social insurance' (mean 3.53, SD .646), and 'expansion of expenditure for social services' (mean 3.26, SD .424). The mean score of the baby-boomers' overall welfare consciousness was relatively high as 3.45 (SD .428), advocating the expansion of welfare expenditure. Second, the independent variables influencing the baby-boomers' welfare consciousness was found to have explanatory power of 12.9%. In the results of regression analysis, variables found to have a significant effect were gender (B=.100, t=2.573, p<.01), personal responsibility for poverty (B=-.151, t=-3.635, p<.01), social responsibility for poverty (B=.149, t=3.437, p<.001), and recipient's laziness (B=.251, t=6.578, p<.001). Based on these results were discussed major relevant policies.

Purpose: The purpose of this study is to investigate the role of social support in the experience of job stress among hospital nurses. Method: This study was carefully designed to overcome methodological shortcomings found in past research, and examined two organizational effectiveness variables(job satisfaction and organizational commitment) as outcome variables. The sample used in this study consisted of 602 nurses from 5 general hospitals. Data were collected with self-administered questionnaires and analyzed using hierarchical regression and LISREL technique. Result: It was found that: (a) three job stress variables(workload, role conflict and conflict with other medical staff) have negative effects on job satisfaction and organizational commitment; (b) social support have positive main effects on the two output variables; (c) the negative effects of job stress variables on job satisfaction and organizational commitment are not buffered by social support, and (d) social support mediates the effects of job stress on job satisfaction and organizational commitment, and the size of the mediating effects is small. Conclusion: Further research needs to be done to further refine this study.

This study tried to find out how to overcome multicollinearity problems in the structural equation model by creating a hierarchical construct model about the repurchase intention of social commerce. This study selected, as independent variables, price, quality, service, and social influence, based on literature review about social commerce, and then, as detailed variables of independent variables, selected system quality, information quality, transaction safety, order fulfillment and after-sales service, communication, subjective norms, and reputation. As results of empirical analysis about hierarchical construct model, all the independent variables were accepted having a significant impact on repurchase intention of social commerce. Next, this study analyzed the competition model that eight independent variables of price, system quality, information quality, transaction safety, order fulfillment and after-sales service, communication, subjective norm, and reputation directly influence the repurchase intention of social commerce. As results of empirical analysis, system quality, information quality, transaction safety, communication appeared to be insignificant. This study showed that hierarchical construct model is useful to overcome the multicollinearity problem in structural equational model and to increase explanatory power.

The purpose of this research was to study the effects of children's temperament, social competence, emotional intelligence, morality and parent's child rearing attitudes on young children's internalizing and externalizing problem behavior. Subjects were l34 five-year-old children attending day-care centers and kindergartens in Seoul, Korea. Analysis of the relationships among these variables was by correlation and stepwise multiple regressions. There were statistically significant correlations among the variables of temperament, social competence and parents' child rearing attitudes and young children's behavior problems. Variables influencing young children's internalizing behavior problems were children's temperament and parents' child-rearing attitudes; variables influencing children's externalizing behavior problems were children's temperament, their social competence, and parents' child-rearing attitudes.

The purpose of this study was to find out the most pursuasive social stratification variables affecting the attitude toward foreign luxury goods and the purchase frequency and examined the difference in the attitude toward foreign luxury goods and the purchase frequency among groups divided by age and social stratification variables. The subjects were 521 married women over 25 years old living in Seoul and Kyong-gi province areas. The data were analyzed by multiple regression, ANOVA, Duncan's multiple range test, frequency and percentage. Social stratification was measured by family's monthly income, educational and occupational levels of married women's and their husbands' for an objective method while economic levels, social status, consumption levels, and cultural levels were used fer a subjective method. The results were as follows; first, the most explainable variables influencing the attitude toward foreign luxury goods and the purchase frequency were age and women's educational levels examined by the objective method of social stratification. Second, according to the subjective method of social stratification, the attitude toward foreign luxury goods and the purchase frequency were affected by age, economic levels, consumption levels, and cultural levels. Consumption levels which showed actual expense per family were the most explainable variable in the purchase frequency.

The present study investigated perception of social authority by children and adolescents removed from illegally built shacks 181 children and adolescents from illegally built shacks and 200 comparative respondants of middle socioeconomic status were investigated. Perception of the social authority figures was classified by 5 categories(self, family member, neighbor, teacher and peer. social authority, collective member) in terms of contactable possibility and psychological distance. The data were analyzed by Hest. The results showed that (1) compared with their middle class peers(M group) children and adolescents from illegally built shacks(S group) perceived social authority figures positively, while they perceived their own family members less favorably. (2) The S group regarded their teachers as more valuable and able than M group. (3) The S group perceived social authority figures, i. e., statemen. polices. national assembly members. public servants and enterprisers, less favorably than their family members. (4) There were main effects of the age and sex variables of respondants. (5) There was an interaction effects between the age. sex and SES variables and was also interation effect between age. sex and task variables in cognition for the social authority figures. There was also an interaction effect between age and SES variables in perception for the personal traits of the social authority figures.

Purpose - The existing marketing studies using Social Network Analysis have assumed that network structure variables are time-invariant. However, a node's network position can fluctuate considerably over time and the node's network structure can be changed dynamically. Hence, if such a dynamic structural network characteristics are not specified for virtual goods purchase model, estimated parameters can be biased. In this paper, by comparing a time-invariant network structure specification model(base model) and time-varying network specification model(proposed model), the authors intend to prove whether the proposed model is superior to the base model. In addition, the authors also intend to investigate whether coefficients of network structure variables are random over time. Research design, data, and methodology - The data of this study are obtained from a Korean social network provider. The authors construct a monthly panel data by calculating the raw data. To fit the panel data, the authors derive random effects panel tobit model and multi-level mixed effects model. Results - First, the proposed model is better than that of the base model in terms of performance. Second, except for constraint, multi-level mixed effects models with random coefficient of every network structure variable(in-degree, out-degree, in-closeness centrality, out-closeness centrality, clustering coefficient) perform better than not random coefficient specification model. Conclusion - The size and importance of virtual goods market has been dramatically increasing. Notwithstanding such a strategic importance of virtual goods, there is little research on social influential factors which impact the intention of virtual good purchase. Even studies which investigated social influence factors have assumed that social network structure variables are time-invariant. However, the authors show that network structure variables are time-variant and coefficients of network structure variables are random over time. Thus, virtual goods purchase model with dynamic network structure variables performs better than that with static network structure model. Hence, if marketing practitioners intend to use social influences to sell virtual goods in social media, they had better consider time-varying social influences of network members. In addition, this study can be also differentiated from other related researches using survey data in that this study deals with actual field data.

As the 4G and 5G Internet technologies become more common and developed, an environment for uploading and watching videos is created and spread, in addition to simply uploading posts. Watching and sharing daily life among media contents called Vlog, are very common more than ever. This means that individual users could access Vlog easily and the situation could be new trend. Additionally, academic research about Volg is increasing. We analyzed three independent variables affecting a perceived enjoyment we set up the dependent variable. Information search, self-expression, and social need are set as independent variables and social interaction is set as the control variable. Information search and self-expression are significant effect to perceived enjoyment except social need. In particular, social interaction as a control variable has effect to all relationships.

The purpose of this study was: (1) to examine relationships between social development and day care quality, child-care experience and family characteristics, and (2) to investigate the explainability of those related variables for social development. Subjects for this study were 252 4-year-old children and their mothers from 32 day care centers in Seoul. Harms & Clifford's Early Childhood Environment Rating Scale was used to measure the quality of day care. The main results were as follows: (1) Day care quality, child-care experience and family characteristics were significantly related to social development. (2) Child's gender, months of age, mother's child rearing attitude, the length of child-care experience, overall quality of day care, and group size significantly predicted social development. 33％ of the variance of social development was explained by these variables. The relative influence of these variables to the prediction of social development was about the same.
