This study explored the perception of internet media credibility and influencing factors among college students who are routine users of internet-based media. Media literacy competences are of primary interest among others in that users' media literacy such as information evaluation, critical understanding of media, and information sharing are assumed to be related to media credibility. The results of analysis revealed critical understanding ability to be statistically significant and consistently influencing factor. Users with more critical view on media ownership, represented reality, commercial intention of media seemed less likely to trust internet media. Whereas media use motive for information was found to be a strong predicting factor, motive for pleasure showed no relationship with credibility. Based on the findings, suggestions for new research and limitations of the study were discussed.

The purpose of this study was to investigate the degree of link with internet media and a internet addiction disposition of adolescents. The subjects were 500 students attending to middle and high schools consisted of male and female. The instruments were "the questionnaire on the present conditions of internet use" consisted of 14 items(Cronbach's α=.71) and "the internet addiction rating scale" consisted of 20 items(Cronbach's α=.73). These questionnaire were revised by this researcher. For data analysis, chisqure and ANOVA were used. The main results were as follows. First, a boy students and the vocational high school and the middle school each have more negative response than a girl students and the humanistic high schools in the present conditions of internet use and the judgement on a harmful object of internet space. Second, a boy students have higher than a girl students in an internet addiction disposition. Third, an internet addiction related with the times link with internet, the type of internet game, and the content of internet space(a lustful and violent objects). The various methods for the prevent with the internet addiction of adolescents discussed with based on the previous studies.

This research explores the empirical confirmation of the Internet development including from the period of innovation to the time of social-cultural use in today. The research focused on how tradition news media rover about the Internet developed from early to today, and understanding the media characteristics on the each stages from news frame. The research Is designed to conduit content analysis from 1989 to 2004, then this research is divided four(4) stages of the Internet development: innovation, diffusion, commercial usage, social-cultural usage. The results shows that there are significant different coverage by the stages. First of all, the news coverage pattern shift from technology focused on early stages to social usage focused on the later stages. This research confirms that the ratio of the seriation(technology) coverage defined when social usage is increased, on the other hand skeumorphs(social usage and content) coverage is increased in the commercial and social usage stages. This coverage pattern among news media does not such a big different and there is no competitive coverage. Moreover, the news coverage shifted from thematic coverage on early stages to episodic coverage while the number of usage increasing. In addition, the tone of coverage has not been changed significantly.

Although it is relatively difficult to eavesdrop the commonly used PSTN in that it is connected with direct circuit, it is difficult to ensure the secret of call on Internet because many users can connect to the Internet at the same time. However, it is needed to ensure secret of voice call in a special situation. Due to the fact that many users can connect to the internet at the same time, VoIP can always be in a defenseless state by hackers. Therefore, in this paper, we have developed the increased voice security internet telephone terminal and measured conversation quality by adopting VPN PPTP based on SIP and using tunnel method in transmitting voice data to prevent eavesdrop of internet telephone.

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.

Korean adults' internet addiction diagnosis measure, K-scale developed by Korea National Information Society Agency (NIA), has composed of 4 categories including 20 items. This scale can diagnose user's internet addiction with individual's questionnaire items. Most of previous research works were tried to know reasons of internet addiction and to judge whether adolescents are addicted or not with their samples. In this research, it is the goal to find the key component to judge individual's internet addiction by using a decision tree in the data mining field and a principal component analysis in statistics. From the experimental results, we would discover that tolerance and preoccupation factor is the most important one to affect adult's internet addiction.
