The purpose of this study is to explore the subjective perception of college students' Internet addiction by applying photovoice method, a participatory research method. The subjects of the study were nine university students at G University. The data were analyzed by orientation, photo collection, photo selection, contextualizing and codifying according to the general photo voice research procedure.As a result, 15 sub-categories were derived based on the meaning of Internet addiction, the effects of Internet addiction on life, and how to get out of Internet addiction. The perception of the meaning of Internet addiction was divided into five categories: 'loss of self-regulation', 'habit without exit', 'disconnection from the world', 'loss of me', and 'voluntary prison'. The effects of Internet addiction on life were 5 categories: 'health deterioration', 'social isolation', 'broken daily life', 'anonymous violence' and 'my discovery and life extension'. In terms of how to get out of internet addiction, 'self-looking', 'new hobbies', 'nearby', 'reality meetings', and 'forced blocking' were derived. It suggested the discussion about Internet addiction viewed by college students and the implications of constructing a counseling program that can help to use the Internet correctly.

Objectives: This study was performed to consider the association between Internet using time for non-educational purposes and adolescent health, and to examine how health status differs between Internet users and non-users. Methods: We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A total of 75 066 adolescents were categorized into four groups according to their Internet using time excluding using for educational purposes: non-Internet users (NIUs), occasional Internet users (OIUs) (<1 h/d), moderate Internet users (MIUs) (${\geq}1$ and <2 h/d), and heavy Internet users (HIUs) (${\geq}2$ h/d). Health factors included eight health risk behavior indices, four mental health indices and six physical health indices. Results: The distribution of Internet use was as follows: NIUs 17.4%, OIUs 68.1%, MIUs 12.7%, and HIUs 1.7%. In multivariate analysis, using OIUs as a reference, U- or J-shaped associations were observed for five health risk behavior indices (current smoking, current drinking, drug abuse, sexual intercourse, sedentary behavior on weekdays) and four mental health indices (stressed, depressed, suicidal ideation, attempted suicide) in both genders. After removing confounding effects, including age, region, school type, subjective school record, subjective economic status, presence of parents, living with family, and sedentary behavior, these associations were still observed. Conclusions: Health professionals should consider both Internet non-users (for non-educational purposes) and heavy users to be high-risk groups in terms of health status. Also, more well-designed studies are needed to clarify what factors are working in these nonlinear associations.

Until now, there have been various studies against Internet worms. Most of intrusion detection and prevention systems against Internet worms use detection rules, but these systems cannot respond to new Internet worms. For this reason, a malicious process control system which uses the fact that Internet worms multicast malicious packets was proposed. However, the greater the number of servers to be protected increases the cost of the malicious process control system, and the probability of detecting Internet worms attacking only some predetermined IP addresses is low. This paper presents a security framework that can reduce the cost of the malicious process control system and increase the probability of detecting Internet worms attacking only some predetermined IP addresses. In the proposed security framework, virtual machines are used to reduce the cost of control servers and unused IP addresses are used to increase the probability of detecting Internet worms attacking only some predetermined IP addresses. Therefore the proposed security framework can effectively respond to a variety of new Internet worms at lower cost.

Activities in fields based on internet virtual reality are flourishing. Education field is not an exception, and has reached the stage of establishing a cyber university after showing its activity in the developing field of distance learning. Although some of the architectural education fields have been following this trend, the education field of architectural design has not been developed as wildly because there have been a lot of difficulties in expressing three-dimensional space on a two-dimensional web. However, it has become possible to actualize the remote lecture based on internet in the education field of architectural design through the latest developments in internet technology. The purpose of this research is to be a basis for developing a teaching method for architectural design by taking advantage of the advanced in virtual reality technology on the internet.

Purpose: This research was conducted to explore the experience of using Internet to solve health problems and to develope a grounded theory. Method: There were 15 subjects in their 30s who had experience using Internet to solve health problems for themselves and their families. Results: 114 concepts, 31 subcategories, and 9 categories were derived from the analysis by using approaches by Strauss & Corbin. Central phenomenon was "Primary healthcare information" and the core category was "Selecting ways to solve health problems". The participants' experiences were conceptualized into two perspectives: reliability of the information and tendency of preference among the sites. Conclusion: All of the processes found on Internet that solved health problems required the assistance of a health professional such as a nurse. It was judged that there are some differences in the degree of usage regarding health-related information, which was primarily in accordance with the confidence and attitude of the user with respect to Internet information. We presented a strategy that could operate with professionals and nonprofessionals. Therefore, we can be satisfied by the fact that this study suggests a complimentary nursing strategy to the healthcare on Internet.

Rapid spread of the internet has made our everyday life more convenient, however it has brought some problems along with it. Especially, undergraduate student are losing their social ability as they become absorbed in the internet game, act selfishly in the cyber space and lose interest in studying. As a result, they become isolated from their friends and experience difficulty in the relationship with their parents. In this paper, the influence factors of internet game addiction is investigated using the Analytic Hierarchy Process (AHP) and statistics techniques. This study is to define the influence an important factors of internet game addiction using a questionnaire to internet game player and expert group. It is believed that this study will be more receptive to results that include the priority weights of internet game addiction among the addiction group, non-addiction group and expert group.

Information and Communication Technologies(ICTs) have substantially enlarged both the opportunities to realize one's human rights but have also resulted in the emergence of new challenges. ICTs are so deeply embedded and cental to almost all aspects of human activity. And ICTs are assuming an increasingly central role in all aspects of human and societal development across the world. But this is especially true of the right to privacy, which faces challenges such as profiling and data mining for public(including national security) and private purposes. ICTs access is a fundamental right for all humans in the information age. So we have need for regulation based on human rights in the digital age. And governments have a responsibility to protect individuals against violations of human rights and data protection by public authorities, but also by private entities. In addition, internet governance and multi-stakeholder principle have to be stressed on all of the internet issues because internet governance is included in the principle of democracy which have bottom-up communication and equality. So it is very importance that Internet Governance Forum is the space for a meaningful discussion on public policy issues relating to the internet.
