Currently, web syndication is usually utilized in desktop environments, but not considering mobile environments. In this paper, we focus on the extension of the desktop based web syndication to the mobile internet. Simply adapting the desktop based web syndication to mobile devices can cause high wireless internet communication cost. We propose PMS(Proxy-based Mobile Syndication) model which achieves low cost mobile syndication. In the PMS model, MWProxy is defined as a proxy server between mobile devices and web sites. It can reduce the communication cost by peeking up modified items from the web sites and reducing the channel size. In this paper, we designed and implemented the PMS system in a mobile phone and evaluated the performance of the PMS system by conducting real experiments using mobile emulators.

This paper proposes on the technical blocking method of Internet harmful pornographic sites which is the most Internet negative-function. At Present, most technical methods based on web sites back-searching or words filtering for blocking the pornographic Internet sites have limitations. For this, this paper proposes the acoustic and image based blocking method for filtering harmful Internet sites. For this, sexual main body parts are extracted by texture analysis and curve fitting. Also acoustic signals are analyzed using pratt tool and auto-correlation function is adopted for matching between prototype signals and test signals. Finally, the effectiveness of this paper is demostrated by several experiments.

The most great web problem that mothers represented was depth of content(43 people) and the other rated as following order; objectivity, specialty and reliability of content(29 people), no problems (23 people), too much advertisements(17 people), obligation on member(4 people). 3. Mothers represented the highest information needs about play and education(65 people) and the other rated as following order; nutrition(44 people), managements of common health problems(39 people), experiences of other parents(10 people), child caring methods (38 people), exchanges of things(7 people). 4. Mothers represented the highest consultation needs about common health problem (62 people) and the other rated as following order; growth and activity(60 people), play and education(30 people), nutrition(22 people), child caring methods(9 people).

A lack of trust in the technical and institutional environments surrounding the web can hinder e-commerce adoption, because Internet social cues are minimal and trust is difficult th establish. Web vendors must act purposefully to overcome consumer perceptions of uncertainty and risk by building trust-both in their own web sites and in the broader Internet environments. Trust makes consumers comfortable by sharing personal information making purchases, and acting on web vendor advice-behaviors essential to wide-spread adoption of e-commerce. Understanding the nature and antecedents of trust is, therefore, a major issue for both Internet researchers and practitioners. Prior research on e-commerce trust has used diverse, incomplete, and inconsistent definitions of trust therefore, making it difficult to compare results across studies. This study tried to and the empirical relationships among the trust-related factors on the usage of Internet shooing mall. The model includes five high-level constructs-disposition to trust institution-based trust trusting beliefs, trusting intention and environmental factors. The results showed that the disposition to trust and the environmental factors had a significant effect on the web site trust however, their effect was not consistent Moreover, the model suggested in this study need to be extended including with the more sociological factors and results in this study required to be verified with those extended model.

With the increasing number and variety of internet users as well as the development of internet technology, web contents have been taking a more comprehensive, integrated, and practical form. This change has brought to our attention the importance of the information architecture and menu design, both of which are required for the users to navigate vast amount of data promptly, correctly and easily for effective communication in the web sites. In this study, web sites were categorized by the service levels provided to the users, and sampling was performed accordingly. Then, information architecture, the layout and the presentation of the menu design were analyzed. The result of the analysis show that there are distinguishable characteristics in how the menus were expressed and designed, and that these characteristics reflect the users' characteristics in the web interface menu design. With the result of this study, we present a guideline for information architecture and web interface menu design, which reflects user characteristics thereby strengthening usability. Using this guideline, we expect the development of web interface design which should support more efficient communication on the web.

Finding the factors to affect the success of the business web sites is critical to enhance their competitiveness. This paper categorizes these factors into 4 quality measures: system, information, service and entertainment. The success is measured via user's satisfaction and loyalty. It surveys 474 Internet users to explore the effect of the quality measures on web site success. We confirm the causal effect of quality factors on users' satisfaction and loyalty. Furthermore, a comparative study is performed for web site types, such as finance, e-commerce(shopping mall), and entertainment. We note that the effect differs in web site types.

Although the Internet has been a important communication tool in modem societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the internet may reflect their personality. This study, also, reveals that controlling the big five personality dimensions, the amount of self-disclosure through ones' social networking site is positively related with subjective happiness. This finding suggests that like confession behaviors in religious or curing facilities, people can use the Internet as a therapeutic or a preventative method for promoting their well-being. Theoretical contributions and practical implications are discussed.
