Objctives: This study purposed to examine the intention to participate in the preventive program of depression of Internet user and to offer the baseline data for development of mental health promotion program. Methods: The internet survey was performed using a self-reported questionnaire on intention to participate in the preventive program of depression, depressive symptom(with Zung's SDS) and so forth from 1,000 internet user (aged $13{\sim}49$ years) via two web sites at Feb($1st{\sim}10th$), 2006. We analyzed the intention to participate in preventive program of depression and the factors related with that intention by depressive level. Results: In the normal group, the intention to participate in a preventive program of depression was influenced significantly by counselling experience(s) on depression(p<.001), and perceived control(p<.001) over the barriers to participation in the preventive program of depression, and marginally by gender. In the depressive group, the smoking habit revealed marginal effect(p=.051) and perceived control over the barriers to participation in the preventive program of depression influenced on that intention significantly(p<.001). Conclusion: Among internet users, especially the solutions of barriers to participate in the preventive program of depression is more important at the intervention program for prevention of depression. In the normal group, we need to consider the use of messages tailored by counselling experience(s) on depression. Some intervention program dealing with two subjects, smoking cessation and prevention of depression concurrently, will be appropriate for the depressive group.

This study was identify web interface design factors for increasing information processing and attention for mentally disabled men. Gaining information via the internet is becoming pivotal in today"s society as the internet is becoming the center of knowledge and information. The goal of this study is to present the guideline of web interface design for the disabled men who are alienated in gaining information from the Internet. If the internet were more user friendly to the disabled men, they would be able to spend more time in doing what they enjoy and also in self development, with the information gained on the internet. This study investigated current portal sites to understand the present situation, surveyed and interviewed the disabled men, and researched literatures on how the disabled men perceive various stimulants and also researched documents for previous guidelines on interface design for them. This study investigated internet sites which the disabled men use to gather information about products and which entice their purchasing desires. The conclusion is that the usability can be improved by eliminating visual dizzy elements in the pages, simplifying the layout and the menu designs which represent the information architecture.

Recently, Internet Protocol TV technology has a latent power for searching information by using internet-connected interactive TV media. It is hard to browse and search web site conveniently since the visual and input devices are not sufficient for navigating through the websites. Zoomable user interface is a possible solution that may reduce users' task load and improve their performance. In this paper, we made three types of web browsers as scroll, physical zooming and semantic zooming type. Fifteen participants asked to do searching tasks and their task time, accuracy and subjective responses are recorded. In the result, though scroll type is evaluated more efficient than other types in task time and accuracy since participants are familiar with scroll type interface, semantic zooming type is highly rated in subjective responses such as perceived searching efficiency, satisfaction and joyfulness. This result implied semantic zooming is a possible solution which is improving user experience of searching websites using Internet Protocol TV.

We examined the factors affecting user satisfaction and persistent intention of use for the Internet-only banking services. Firstly, this study extracted factors that influence the acceptance of Internet-only banking services based on previous studies. The purpose of this study is to investigate the effect of perceived relative advantage, perceived convenience, perceived usefulness as independent variables based on Technology Acceptance Model for two dependent variables ; user satisfaction and intention for continuous use for internet-only banking service. The study showed that perceived relative advantage, perceived convenience, and perceived usefulness have a significant effect on user satisfaction and intention for continuous use as a result of an empirical analysis of 204 customers of internet-only banking services. Based on the results of the study, some practical implications for customer retention are suggested.

To launch effective mobile Internet marketing strategies, firms need to understand mobile Internet user behavior. Thus in this study we investigated factors that affect on the repurchase intention of mobile Internet users. A random sample of 501 users was surveyed. Overall satisfaction (mediating factor), flow and interactivity factors (initial factor) were found to have the most significant impact on the reuse intention and discrepancy factor is not significant to the reuse intention.

In this paper, we discuss about mobile Internet security. The past few years have seen unprecedented growth in the number of wireless user, applications, and network access technologies. Wireless Internet is similar to wired internet, but it has some constrained wireless environment. So many internet technologies for wireless are developing now

Becoming Internet is public, various services using Web are created. Internet auction is not exceptional but make rapid progress. Internet auction system damages user because its security is not perfect and faultless. In this paper, we propose a design of internet auction system providing more secure and convenient environment.

This research which applied with Uses and Gratification Theory tried the comparative analysis between internet purchasers and internet non-purchasers by the user's motivation, attitudes, and behavior in Mongolia, By utilizing the two-group discriminant analysis method, which tested the hypotheses of this study. In Internet Market of Mongolia, This research classifies all internet consumers into internet purchasers, and non-internet purchasers and examines the differences in motivations, behaviors, and attitudes between the two groups; based on the assumption that these two groups have different needs and expectations while using the internet. The two group discriminant analysis was conducted to identify a lot of differences between the two groups. Research results show that important differences are found in motivations for using the Internet, attitudes toward the Internet, amount of Internet usage, and frequency of visiting a certain type of Web site. In the practical aspect, This result provides an understanding of the Mongolia Internet shopping, also it could give some valuable implication for the Internet company marketers who are trying to find out how to penetrate into Mongolia internet market.

This paper presents "The 3-User NOR switching channel based on interference decoding with receiver cooperation" in succession to "Jeju Jong Nang channel code I, II". The Jeju Jong Nang code is considered as one of the earliest human binary coded communication (HBCC) in the world with a definite "1" or "0" binary symbolic analysis of switching circuits. In this paper, we introduce a practical example of interference decoding with receiver cooperation based on the three user Jong Nang NOR switching channel. The proposed system models are the three user Jong Nang (TUJN) NOR logic switching on-off, three-user injective deterministic NOR switching channel and Gaussian interference channel (GIC) with receiver cooperation. Therefore, this model is well matched to Shannon binary symmetric and erasure channel capacity. We show the applications of three-user Gaussian interference decoding to obtain deterministic channels which means each receiver cooperation helps to adjacent others in order to increase degree of freedom. Thus, the optimal sum rate of interference mitigation through adjacent receiver cooperation achieves 7 bits.
