With the appearance of wireless spectrum crisis in traditional cellular network, device-to-device (D2D) communication has been regarded as a promising solution to ease heavy traffic burden by enabling precise content delivery among mobile users. However, due to the channel sharing, the interference between D2D and cellular users can affect the transmission rate and narrow the throughput in the network. In this paper, we firstly present a weighted interference minimization cluster formation model involving both social attribute and physical closeness. The weighted-interference, which is evaluated under the susceptible-infected(SI) model, is utilized to gather user in social and physical proximity. Then, we address the cluster formation problem via spectrum clustering with iterative operation. Finally, we propose the stable matching theory algorithm in order to maximize rate oriented to accomplish the one-to-one resource allocation. Numerical results show that our proposed scheme acquires quite well clustering effect and increases the accumulative transmission rate compared with the other two advanced schemes.

This study attempts to examine the relationship between human resource management and turnover rate in social welfare organizations in Korea. For the analysis, this study utilizes '2012 Central Government Social Welfare Facilities Evaluation(CGSWFE)' data and employs multiple regression analysis for examining the research model and questions built on previous studies. The key findings of this study are as follows: first, the annual average turnover rate in social welfare centers in Korea is 16.7%; second, after controlling other organizational factors, average pay, substantial system of supervision, and competence of supervisors have significant relationships with turnover rate in a negative direction; and third, availability of employment alternatives which is one of control variables also has significant and very strong relationship with turnover rate. The findings indicate that suitable compensation and supervision system with high quality would be important factors to decrease turnover rate in social welfare organizations facing increased competitions. This study provides new knowledge foundation on the relationship between human resource management and turnover rate in social welfare organizations. In addition, it contributes to advancing new discussions about turnover by analyzing real turnover behavior at organizational level which is completely different from the previous research focusing on turnover intention at individual level.

The purpose of this study is to investigate the mediating role of proactive behaviors in the mechanism which job crafting affects organizational effectiveness. Through this study, we tried to contribute to the following theoretical and practical aspects. First, we tried to extend the theoretical discussion by identifying the relationship between job crafting, proactive behavior, and organizational effectiveness. Second, we provide practical implications for Korean organizational members based on proven job crafting, proactive behavior, and organizational effectiveness, and contribute to creating a work environment that enhances job satisfaction and reduces turnover intention. The results of this study are as follows. First, increasing structural job resource, increasing social job resource and increasing challenging job demand, which are sub-factors of job crafting, had a positive effect on job satisfaction. Second, increasing structural job resource, increasing social job resource and increasing challenging job demand, which are sub-factors of job crafting, had a negative effect on turnover intention. Third, job crafting had a positive effect on proactive behavior. Fourth, proactive behavior mediated the relationship of increasing structural job resource, increasing social job resource, increasing challenging job demand, and job satisfaction. Fifth, proactive behavior mediated the relationship of increasing structural job resource, increasing social job resource and turnover intention. This study provides an understanding of the impact of job crafting on organizational effectiveness and is expected to contribute to future research on job crafting.

The purpose of this ethnography is to describe and analyze the wild-goose mother's everyday life, her family relationships, and her social networking. Thirteen mothers from New York, California, and Texas, U.S.A., were interviewed with an unstructured questionnaire. Their residency and everyday schedules are arranged around the children's educational conditions. They have experienced difficult relationships with Korean American immigrants, Korean students, other wild-goose mothers, and Americans. They have failed to develop their social capital effectively due to the language barrier and a cultural capital deficiency. As a kind of family strategy, this separation sometimes strengthens the spousal relationship, preventing divorce, but usually weakens the emotional ties and quality of communication between husband and wife. The acculturation gap between the mother and her children may cause the mother to become alienated and exacerbate the generational conflict.

This paper makes some contributions on optimal environmental taxes in the generalized utilitarian social welfare function. It is not to suggest as to appropriate environmental tax rates but to contribute the direction of environmental tax policy. The tax rates depend on parameters of individual utility function (CES utility function) and social welfare function and income tax rate. The major findings are that, as the elasticity of substitution between labor and leisure and the concavity of social welfare function increase, both the optimal tax rates and the government demogrants rise. And, as the parameter of environmental pollution in the individual utility function increases, the optimal tax rates also increase. For the future study, this model involves the income tax and the capital tax as endogenous variables and the wage changes due to international trade.

The purpose of this study was to investigate the actual conditions of successful ageing and the influencing factors focusing on social support from family and friends to improve elderly's quality of life. The 300 respondents, all participants in programs at facilities for the elderly, were interviewed via a questionnaire. The collected data were analyzed using SPSS 23.0. The results are as follows. First, the average score for successful ageing among the participants was above average. Second, the level of successful ageing varied according to income and religion. Third, the common variables affecting active or emotionally successful ageing were support from friends, subjective health conditions, and gender. It is suggested that the community should be informed of the importance of support from family through educational programs, as the elderly still want the support of family despite family's reduced role.

The purpose of this study is to investigate the participation in social activities by full-time housewives with infants and preschool children. The data in this study comes from a 1 percent free sample of the 2010 Population and Housing Census collected by Statistics Korea. The statistical methods for this study were percentage, chi-square test, and logistic regression analysis. The findings are as follows. First, there are differences in participation in social activities according to number of infants, number of preschool children, and number of elementary schoolchildren. Second, there was the difference in participation in social activities between full-time housewives and full-time wives' husbands. Third, factors like full-time housewives' age, educational level, number of preschool children and elementary schoolchildren, number of rooms, and occupancy status affected participation in social activities by full-time housewives. These results show that full-time housewives were under pressure in relation to participation in social activities because of their caregiving labor but participated in religious and educational activities actively.

This study aims to discuss the role and function of social capital in explaining social risk perception among female-headed households. This study analyzed the level of social risk perception and its determinant factors of female-headed households using 2020 Social Survey data from Statistics Korea. The analysis revealed that socio-demographic factors and social capital influenced the perception of social risk. In addition, the social capital related to social safety was associated with the level of social risk perception. Even after controlling for various factors, the social risk perception level among female-headed households was higher than among male-headed ones. Among female-headed households, social capital such as compliance with regulations or ability to cope with risk; demographic factors such as age, residential area, and health status; and economic factors such as income level and housing type were found to affect social risk perception. Based upon the findings this study devises ways to accumulate social capital that can be obtained in cooperative relationships between families and communities.

In this study, we investigated the effect of family values and the resource factors provided by parents on marriage intention among men and women in their 30s and 40s who have never married. The study participants were 300 never-married men and women in their 30s and 40s living in Seoul and its suburbs. The participants were chosen via purposive sampling. The study results are follows. First, according to the analysis of the subjects' family values and the resource factors provided by parents, both family values and the resource provided factors by parents showed higher scores than the median. Subjects had higher scores than the median score in regards to marriage intention, indicating that they had a greater intention to marry. Second, a multiple regression analysis was conducted to identify the effect of the socio-demographic characteristics of subjects, family values, and the resource factors provided by parents on marriage intention. As a result, age, the need of marriage and gender-role attitudes prevalent in family values, and the economic resources among the resource factors provided by parents had significant effects on marriage intention. Thus, the older the age of the subjects, the more traditional the view of marriage and gender-role attitudes, and the greater the amount of economic resources provided by parents, the greater the subjects' intention to marry.
