Objectives: To investigate the association of problematic Internet use with oral health behaviors and oral health status in a nationally representative sample of Korean adolescents. Methods: Data from the 2010 Korea Youth Risk Behavior Web-based Survey (73238 Korean adolescents; mean age $15.06{\pm}1.75years$; age range, 12-18 years) were used. Problematic Internet use was measured using the Korean Internet Addiction Proneness Scale for Youth-Short Form. Self-report questionnaires were used to assess oral health behaviors and oral health status of adolescents. Results: Problematic Internet users were less likely to brush their teeth frequently [adjusted odds ratio (AOR)=0.59; 95% confidence interval (CI)=0.56-0.63] and at school after lunch (AOR=0.89; 95% CI=0.83-0.94) as well as more likely to perceive their oral health to be poorer (AOR=1.63, 95% CI=1.54-1.72) and experience oral symptoms (AOR=1.75, 95% CI=1.65-1.86) compared to usual Internet users. Conclusion: The study results indicate that problematic Internet use may adversely affect the oral health of Korean adolescents. Thus, oral health screening and Internet-based education are needed for adolescents experiencing problematic Internet use.

Internet of Things(IoT) is electronic devices and household appliances use wireless sensor network in environment of high speed wireless network and LTE mobile service. The combination of the development of Internet and wireless network led to development of new forms of service such as electronic devices and household appliances can connect to the Internet through various sensors and online servers such as a Home Network. Even though Internet of Things is useful, there are problems in Internet of Things. In environment of Internet of Things, information leakage could happens by illegal eavesdropping and spoofing. Also illegal devices of wireless communication interference can cause interfere in Internet of things service, physical damage and denial of service by modulation of data and sensor. In this thesis, it will analyze security threats and security vulnerability in environment of mobile services and smart household appliances, then it will suggest plan. To solve security issues, it is important that IT and RFID sensor related companies realize importance of security environment rather than focus on making profit. It is important to develop the standardized security model that applies to the Internet of Things by security-related packages, standard certification system and strong encrypted authentication.

This study examined the moderated effects of self-control on the relationship between elementary school children's excessive use of the Internet and their stress levels. The participants were 403 elementary school children from Chungnam-do. The instruments used were the 'Internet Addiction Autodiagnosis Scale (K-Scale)', the 'Stress Scale' and the 'Self-control Rating Scale'. The collected data were analyzed by t test, F test and the Scheffe test for a post hoc test, Pearson's partial correlation and stepwise multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program (17.0 version). The results were as follows : First, it was found that there were significant differences in terms of excessive use of the Internet, stress levels, and self-control by gender, grade, academic achievement, the beginning year of first Internet access and the number of hours of Internet usage hours per day. Second, there were significant positive correlations between excessive use of the Internet (r = .40, p < .001) and stress levels (r = .44, p < .001) and the immediate satisfaction of self-control. Finally, the immediate satisfaction of self control was seen to moderate the relationships between the total scores for the excessive use of the Internet and stress levels and between withdrawal of excessive use of the Internet and the accompanying stress levels.

Third, impulsiveness was directly influenced by internet-related delinquencies in both male and female students. In male students, their school departments indirectly influenced internet-related delinquencies by way of open communication with mothers, peer support, self-esteem, and impulsiveness. In female students, school departments directly influenced on internet-related delinquencies and indirectly by way of peer support, self-esteem and impulsiveness. Internet-related delinquencies by male and female students were not directly influenced by peer support and self-esteem.

본 연구는 인터넷 상에서 영화에 대한 언급 점유율과 영화 티켓 예매율의 관계를 분석하였다. 국내 대표적인 포털사이트인 네이버에서 제공하는 블로그, 카페, 뉴스, 동영상과 같은 서비스에서 영화에 대한 언급과 영화 예매율 간의 상관관계를 실증 분석하였다. 분석결과 인터넷 언급 점유율과 영화 예매율이 유의미한 정의 상관관계가 있다는 것을 파악할 수 있었다. 구체적으로 흥행 시점 이전은 동영상 채널이 다른 채널에 비해 상대적으로 관련성이 높은 것으로 나타났으며, 흥행시점 이후부터는 블로그와 카페에 보다 높은 관련성이 있는 것으로 파악되었다. 이를 통해서 인터넷 상에서 영화에 대한 언급은 인터넷 채널과 시차에 따라 영화 예매율과의 관련성이 다르다는 것을 파악할 수 있었다.
