This study examines the roles of user resistance and social influences on the acceptance and continuous usage of smartphones at different stages of adoption. The respondents were classified into three groups according to their innovation adoption stage : non-user group, the potential user group and the trial user group. Theories relevant to user resistance, social influences including normative social influences and informational social influences, as well as user adoption and continuance behavior were reviewed and integrated into our research model. In order to verify the proposed structured equation model, we conducted an online survey by targeting mobile phone users and collected data to be analyzed through a partial least squares (PLS) test. This study tested whether there exists differences in the effects of user resistance and different types of social influence on user's adoption or continuance intetion among these three groups. The results showed that user resistance exists in all adopter groups and that it has significant negative influences on intention to use a smartphone. The findings also revealed that user resistance can be enhanced or resolved by two types of social influence; informational social influence resolves user resistance regardless of the adopter category, while normative social influence enhances the user resistance of potential users. Furthermore, the findings show that social influence regardless of the type positively affects user intention. Several theoretic and practical implications pertaining to the results are discussed.

A user influence discrimination scheme using big data from social networks is needed. In this thesis, we propose a user influence discrimination scheme considering reliability in social networks. The proposed scheme measures reliability scores through social activities and simplifies a social network by collecting only reliable users. It also derives user influence by considering direct and indirect influences that depends on network degree between users. As a result, the proposed scheme improves the expandability of the user influence. In order to show the superiority of the proposed scheme, we compare it with the existing scheme through performance evaluations in terms of reliability and user influence.

This study deals with the psycho-social development of children raised by disabled parents. In particular, we are willing to examine the influence of parental factors such as social engagement and future forecast on the change of children's psycho-social development. Using the three waves of Korean Welfare Panel Study data, these predictors were examined through the Latent Growth Curve Modeling. The result shows that parent's disability has a negative influence on their children's psycho-social development. However, similar to the findings of the previous studies, the degree of this influence tends to be decreased as children grow up. Lastly, two parental factors have a direct influence on the psychological development of children. Furthermore, parent's social engagement has an indirect influence on the change of sociality of children through the psychological change of them. This result means that we should encourage disabled parents to participate actively in social activities and think positively about their future.

This research paper is focused on a theoretical study of the influences the structural factors and social capital within an industrial cluster have on innovative performance, and expanding the understanding of the influence through positive analyses based on public surveys. The study adopts a concept of social capital that can formulate a social relationship, and maintains that the social capital either works as a mediator for structural factors or independently exerts strong influences on innovative performance. In the research, the social capital is divided into two categories, bonding social capital and bridging social capital, and their influences are analyzed separately. The result of the analyses shows that unlike the traditional perception based on Korea's unique culture, the influence of bridging social capital is stronger than that of bonding social capital. It is also found that the structural factors exert influence by themselves on the contrary the previous study, simultaneously they still have influence upon innovative performance through bridging social capital calculated via the elements such as secondary relationships, network activity support and organizational openness.

Purpose: This study was conducted to examine the personal and social environmental factors affecting leisure time physical activity (LTPA) among adults living in rural communities. Methods: A cross-sectional study was conducted with a convenience sample of 282 adults living in three rural towns of Chungcheongbuk province. Leisure time physical activity was assessed through the Korean version of the Global Physical Activity Questionnaire (GPAQ), and social influence and social cohesion of social environment were assessed using reliable and validated measures. Multiple logistic regression analysis was conducted to explore personal and social environmental factors associated with LTPA. Results: The overall prevalence of leisure-time physical activity (LTPA) was 40.0%. Multiple logistic regression analysis showed that LTPA participation was associated with gender (OR=2.60, 95% CI=1.47-4.58), healthy eating (OR=1.15, 95% CI=1.01-1.31), unhealthy eating (OR=0.70, 95% CI=0.53-0.93) and social influence for physical activity (OR=1.11, 95% CI=1.03-1.20). However, social cohesion was not correlated with engaging in LTPA. Conclusion: Both personal and social environmental factors are associated with LPTA among rural adults living in Eup-Myen regions. Interventions to promote LTPA would likely benefit from considering healthy dietary intake and social influence for physical activity.
