The current study examined the effects of the voters' perception of television news coverage of election poll results on their political participation intention. 700 voters participated in a telephone interview three weeks before the 2012 Korean presidential election. A structural equation modeling with the nationally representative sample was performed. The findings indicate the respondents were more likely to evaluate television news coverage of election poll results negatively when the news coverage presented that the candidate they supported was behind in the race, and the negative evaluation was linked to a greater third-person perception. The third-person perception, in turn, had an indirect effect on political participation intention through negative emotional responses. The results imply that voters' political position influences their perception of the television news coverage of election poll results, and this perception can have indirect effects on political participation.

Social Networks such as 'Facebook' and 'Myspace' are regarded as useful tools for people to share interests and maintain or expand relationships with other people. However, they pose the risk that personal information can be exposed to other people without explicit permission from the information owner. Therefore, we need a solution for this problem. Although existing social network sites allow users to specify the exposing range or users who can access their personal information, this cannot be a practical solution because the information can still be revealed to third parties through the permitted users albeit unintentionally. Usually, people allow the access of unknown person to personal data in online social networks and this implies the possibility of information leakage. We could use an access control method based on trust value, but this has the limitation that it cannot reflect the quantitative risk of information leakage. As a solution to this problem, this paper proposes an access control method based on a synthesized metric from trust and risk factors. Our various experiments show that the risk of information leakage can play an important role in the access control of online social networks.
