The purpose of this study is to investigate whether there is a need to adopt new media usage variables as additional demographic variables. For the study, 500 Daejeon citizens were surveyed in July 2011 and the results were analyzed. It was confirmed that demographic variables such as gender, age and income still have effective explanatory power, but the explained variance of dependent variables was not stable. Regression analysis with the addition of new media usage variables(internet, SNS, smart phone) showed a significant increase in explained variables in three out of ten issues(global warming, use of public transportation, support of the current administration's national policies). Although the new media usage variables failed to consistently explain variance on several issues, they may be necessary to understand the public support of national policy or new agenda like global warming.

The boycott of Japanese products triggered by Japan's economic retaliation has heated up the Republic of Korea. This study examined the factors affecting the boycott participation intention in 217 college students and ordinary people in their 20s and 30s. The results of the study showed that perceived egregiousness, self-efficacy, and subjective norm had a positive effect on boycott participation intention, and perceived egregiousness had an indirect effect on boycott participation intention through anger. In addition, these overall impacts were moderated by online and SNS news usage. This study is significant in providing academic and practical implications for understanding boycott phenomena by verifying various influencing factors on consumer boycott intentions and comprehensively reviewing the mediating effect of anger and the moderating effect of online and SNS news usage.

The purpose of this study is to empirically address the influences of motives for using SNS on relational bridging and relational bonding in SNS and motives for continuous use SNS by applying the concepts of bonding and bridging, defined in the social capital theory, and major motives for using SNS are classified into three categories-social, information, and recreation categories - based on the previous studies and the usage and gratification theories. Through this study, it was revealed that motives of all these three categories-social, information, and recreation categories-have significant influences over relational bridging and relational bonding in SNS while relational bridging and relational bonding in SNS have significant influences over consistent motives for using SNS so the hypothesis of this study is accepted. It was also proven that motives of all these three categories - social, information, and recreation categories-for using SNS are important factors for creating new communities or expand relationships with other SNS users sharing similar interests. In addition, it was found that SNS users constantly use SNS to build relationships that could create a strong bond between individuals and receive emotional supports when necessary and to expand its own network by creating new relationships with other SNS users.

Many empirical studies indicate that SNS use has increased substantially over the last few years. People use SNSs for social purposes, mostly related to the maintenance of existing offline contacts. Such usage may have led to compulsive use of SNSs resulting in addictive behavior. This paper aims to explore factors affecting SNS addiction. Specifically, the study examined the role of personality traits in the Facebook usage among college students. Compared to the rest of world, daily log on the site has grown very quickly in South Korea. And college students constitute a vast majority of Facebook users in South Korea. Results from a survey of 235 college students revealed that extraversion and neuroticism positively predicted Facebook usage. Students who were high in extraversion were more likely to update their profiles, share photo and images with others and give feedback on other's posts. Similarly, those who were high in neuroticism were more likely to share photo and images with others and update their profiles. These findings support previous research. Furthermore, in terms of the effect of personality on SNS addiction, this study found that consciousness was negatively associated with Facebook addiction, while extraversion and neuroticism were positively associated with Facebook addiction. Based on these findings implications and directions for futures studies are discussed.

In this study, we classified SNS into open and closed types, and empirically examined in which SNS activity the privacy paradox holds. The idea comes from the argument that privacy paradox may be observed differently in the open SNS, which is more vulnerable to the leakage of personal information due to public profiles, and the closed SNS, which is relatively less vulnerable by limiting the range of acquaintances, The results of the empirical analysis are as follows. First, in case of SNS usage, the privacy paradox holds in the overall SNS activities, but different conclusions are drawn according to open and closed SNS. In particular, it is found that as privacy concerns increase, individuals respond in a reasonable and desirable way to reduce SNS activity in the open SNS, which is more susceptible to infringement. Second, in the case of SNS activity intensity, (i) heavy users are more seriously aware of the probability of privacy infringement than light users, so there is a reasonable response to reducing the intensive margin with increasing privacy concerns, and (ii) this tendency is more clearly observed in open SNS, which is more vulnerable to privacy infringement. Accordingly, insisting that the privacy paradox is empirically established by observing only the overall SNS activities without distinguishing them into open and closed SNS may be interpreted as a "Fallacy of Composition."
