This study analyzed the causes of over-flow of adolescent games as loneliness, lack of self-control, parents-open communication, peer-emotional support and the game motivation(immerse, social relations, achievement). For analysis, the research data, 'Game User Panel Research(1 to 4 years)', was provided by Korea Creative Content Agency. As a major result, adolescence loneliness and lack of self-control directly affected game over-flow, and the game's achievement motive in their relation of influence was mediated. Over time, the structure of the relationship between the cause and the effect has shown mostly consistent results.

Recently, dating violence has emerged as a serious social problem, but there is not enough research on controlling behavior among the subtypes of dating violence. Thise study explored the relationship between psychological entitlement and controlling behavior, and the mediation effect of social dominance orientation and social comparison orientation. Furthermore, the study examined if the mediation effect of social dominance orientation between psychological entitlement and controlling behavior differed by gender. As a result, the higher the level of psychological entitlement, the stronger the level of social dominance orientation, social comparison orientation, and the controlling behavior. In addition, the stronger the level of social dominance orientation and social comparison orientation, the more frequently was the occurance of the controlling behavior committed. The level of social dominance orientation mediated the relationship between psychological entitlement and controlling behavior. The level of ability comparison orientation mediated the relationship between psychological entitlement and controlling behavior. The mediation effect of social dominance orientation between psychological entitlement and controlling behavior was moderated by gender. In other words, the mediation effect of social dominance orientation between psychological entitlement and controlling behavior was significant for the male, but not for the female. The limitations of the study and suggestions for further research were discussed.

Purpose: This study was conducted to examine the behavioral intentions of breastfeeding in single women using the theory of planned behavior. Methods: The questionnaires were distributed to 350 single women in her 20~30s, and 316 respondents were analyzed by descriptive statistics, Spearman's correlation, and multiple regression analysis. Results: The subjects showed strong intentions and favorable attitudes toward breastfeeding. The subjects were more favorably influenced by their mothers, siblings, friends, and coworkers who previously experienced breastfeeding than ones with no breastfeeding experiences. There were significant correlations between breastfeeding intention and attitudes (r = 0.321, p < 0.0001), subjective norms (r = 0.434, p < 0.0001), and perceived control (r = 0.307, p < 0.0001). However, regression analysis with two different age groups revealed that subjective norms (p < 0.0001) and perceived control (p < 0.001) contributed to the model of explaining breastfeeding intentions in subjects who were 25 years old or younger, whereas attitudes did not. In addition, subjects who were more than 25 years old showed that attitudes (p < 0.003) and subjective norms (p = 0.002) contributed to the model of explaining breastfeeding intentions while perceived control (p < 0.070) showed less contribution. Conclusion: These results suggest that the theory of planned behavior can be a useful tool to increase the rate of breastfeeding intentions in single women when designing educational materials, which requires consideration of age differences.

This study was conducted to investigate the effects of a career preparation program (CPP) on self-leadership (SL) and career locus of control (CLOC) among University Students in South Korea. Self-leadership is the ability to control and lead oneself to achieve goals. CLOC is that attribute own's success of failure to own's effort and ability internally or luck or environment externally. Both have been known to strongly affect variables associated with career planning. We also explored SL and CLOC based on the variable related subjects' characteristics. Method: After receiving informed consent, 58 subjects were collected from University in D metropolitan area in Korea from March to June 2016. CPP was provided to college students who agreed to join this study, which consisted of a 15 week career development program. During the program, recruitment information was provided as well as encouragement and motivation. The program also focused on self-exploring and self-initiating experiences by themselves. Data were collected before and post CPP and were analyzed using SPSS 21.0. Result: self-leadership increased from $3.02{\pm}0.36$ points to $3.23{\pm}0.35$ points after CPP (t=-4.45, p=0.00). There were significant differences in self-leadership and in internal attribution (t=-3.26, p=0.00). The CPP based on the understanding of oneself was effective to cultivate university students' self-leadership. Moreover, the CPP increased internal attribution of the college students significantly from $2.96{\pm}0.35$ points to $3.15{\pm}0.32$ points (t=-3.26, p=0.00). CPP was also found to effectively influence the internal locus of control. Although external attribution was reduced from $2.19{\pm}0.31$ to $2.13{\pm}0.35$, this different was not significant (t=1.68, p=0.09). Conclusion: The results of this study suggest that the CPP based on understanding of oneself should be actively applied in career education.

This study recognizes that the externalizing problem behaviors of child with disabilities are the result of the social interaction between mother and child, and empirically verifies its systematic causal structure and multidimensional influence relationship. It was attempted to derive practical implications that can help the smooth normalization process of children's families. Therefore, 135 children with disabilities and their mothers selected by convenience sampling were targeted, and in the relationship between maternal overprotective parenting and externalizing behaviors of child, effortful control was used as a mediating variable, and defense style of mothers and children was used as a moderating variable. A Conditional Process Analysis(CPA) that can verify the moderated mediation Effect was performed by establishing a research model. As a result of the analysis, first, the overprotective parenting behavior of mother was statistically significant in both direct and indirect effects in increasing externalizing behaviors of child, and the mediation effect by effortful control was also statistically significant. Second, it was confirmed that the moderated mediation effect of effortful control by the mother's defense style was statistically significant, and the moderated mediation effect of effortful control by the child's defense style was not statistically significant. Based on the above results, assuming the importance of the influence of maternal parenting, a direct strategy for change in maternal overprotective parenting, child's Practical implications of parallel strategies with the tendency toward effective control and suboptimal strategies through the application of mothers' coping strategies were discussed.

This study aims to examine the level of precariousness among young adults in South Korea and analyze the factors affecting their subjective well-being by adopting the three forms of precariousness suggested by Rodgers(1989) such as lack of resource, uncertainty and disempowerment as its analytical framework. Structural Equation Model was used for analyzing the path model of self-rated health, income level and social support(three forms of resource) affecting subjective wellbeing through uncertainty and disempowerment. Study population include young adults aged between 19 to 34 with a sample size of 415 using data of the 8th wave of the Korean General Social Survey(KGSS), 2010. Study population is divided into lower-age group (aged between 19-26) and upper-age group (aged between 27-34) in order to examine the differences between age groups by using Multiple Group Analysis. Study results show that three forms of resources, uncertainty and disempowerment had direct effect on the subjective well-being of South Korean young adults and disempowerment had the most significant effect among the factors. In addition, self-rated health and income level had indirect effect on subjective well-being through both uncertainty and disempowerment while social support had indirect effect on subjective well-being only through disempowerment. Results from the Multiple Group Analysis indicate that among the two age groups, income level only has a significant effect on subjective well-being in the upper-age group. In addition, disempowerment had greater effect on subjective wellbeing among upper-age group than the lower-age group. Based on the study results, this paper suggested policy implications and discussion for further research.

Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.
