Objectives : Internet became essential component in these days. This study primarily tried to find out the characteristics of high risk internet users through using the communication scale. Methods : We investigated levels of internet addiction using Internet Addiction Scale in 1,193 high school and middle school students. Participants were divided into 3 groups (high risk user group, potential risk user group, normal user group) according to the results from internet addiction scale. We additionally surveyed characteristics of internet use, and patterns of communication and Communication Scale based on Satir theory in 614 from 1,193 participants. Results : Boys showed higher tendencies for internet addiction than girls in internet addiction scale. There were significant differences in mean computer using time especially during weekends among 3 internet user groups. The distribution of communication types in each internet user group was similar and this finding coincided with previous study results. However high risk user group showed higher scores in each inadequate communication pattern such as placating, blaming, super-reasonable and irrelevant stance. Conclusion : These results suggest that adolescents who use internet in addictive patterns may have more problematic communication styles and these may be associated with poor interpersonal relationships.

This paper analyzes the effect of network neutrality regulation on social welfare using the two-sided market under the network congestion. This paper deals with zero price rule regulation which means the price regulation on the side of content. The results are as follows : First, under the monopoly platform, internet use price, contents price, and the number of internet user and content provider are all decreasing as the network congestion increases. Second, under the monopoly platform internet use price, contents price, and the number of internet user and content provider are all increasing as the network capacity increases. Third, the price of internet use and contents internet use which maximize social welfare are increasing and the number of internet user and content provider are decreasing as the network congestion increases. Fourth, optimal network capacity for monopoly platform provider is less than socially optimal network capacity. Fifth, if network neutrality regulation is enforced, the price of internet use is higher than monopoly platform provider and the price of contents is lower than monopoly platform provider. Also, the number of internet user is less than monopoly platform provider and the number of content provider is more than that. By the way, when network congestion increases, internet use price, the number of internet user, and the number of content provider are decreasing. Sixth, network neutrality regulation is more effective for internet user side than contents provider when network congestion is considered. This means that network neutrality regulation is not effective for contents market side when network congestion is seriously large.

This paper investigates the relationship of service quality and user satisfaction in the wired and mobile Internet services based on the integrative framework of both systems. Given a moderate level of reliability and validity, the commonly driven dimensions for measuring service quality include responsiveness, assurance, empathy, convenience, usefulness, and diversity. User satisfaction is measurable by the dimensions of communication/entertainment, finance/economics, location/geography, and information/consulting. We apply the MANOVA tests to evaluate whether each of the service quality dimensions has an overall influence on user satisfaction. Next, multiple regression analyses are conducted to check if unique positive effect exists between each combination of service quality dimensions and user satisfaction dimensions. The results show that service quality must be taken care of with respect to the assurance dimension in order to enhance customer satisfaction in the dimensions of location/geography, which will contribute to increasing the utilization of mobile service. For improving user satisfaction in the dimension of information/consulting, service quality must be supported with respect to assurance and empathy in the mobile Internet market, in addition to diversity, which is the only significant service quality in the wired Internet service.

The purpose of this study is to provide empirical and quantitative analysis on user's perceived privacy, security, and user satisfaction when providing visualization information about objects and service provider behaviors that users can not perceive in internet service process. Through previous research, we have examined the importance of privacy and security factors as a key factor to be considered for the characteristics of the Internet of things and the Internet of things. In addition, service blueprint, which is one of the service design methodologies to examine the flow of service usage in providing Internet service of things, was examined. In the flow of things internet service utilization, it is found that the things that are out of the user's cognitive area and the behavior of the service provider take up a large part. Therefore, the hypothesis that the trust of the Internet service security and the satisfaction of the user experience can be improved by providing the security visualization information about the behavior of the object and the invisible service provider in the non-contact aspect of the user and the object. In order to verify the hypothesis, we conducted experiments and questionnaires on the use of virtual objects' internet environment and conducted statistical analysis based on them. As a result, it was analyzed that visual information feedback on non - contact and invisible objects and service provider's behaviors had a positive effect on user's perceived privacy, security, and satisfaction. In addition, we conclude that it can be used as a service design evaluation tool to eliminate psychological anxiety about security and to improve satisfaction in internet service design. We hope that this research will be a great help for the research on application method of service design method in Internet environment of objects.

Due to the development of the Internet, Internet banking that we are liberated from time and space has evolved into banking system. So modern life became comfortable. However, Dysfunction (malicious Information leakage and hacking etc.) of the Internet development has become a serious social problem. According to this, The need for security is rapidly growing. In this paper, we proposed the Internet Banking Authentication System using a dual-channel in OTP(One Time Password) authentication. This technology is that A user transfer transaction information to Bank through one Internet channel then bank transfer transaction information to user using the registered mobile phone or smart phone. If user confirm transaction information then bank request user's OTP value. User create OTP value and transfer to bank and bank authenticate them throgth the ARS. If authentication is pass then transaction permitted. Security assessment that the proposed system, the security requirement that the confidentiality and integrity, authentication, repudiation of all of the features provide a key length is longer than the current Internet banking systems, such as using encryption, the security provided by the Financial Supervisory Service Level 1 rating can be applied to more than confirmed.

In the current Internet system, there are many problems using anonymity of the network communication such as personal information leaks and crimes using the Internet system. This is why TCP/IP protocol used in Internet system does not have the user identification information on the communication data, and it is difficult to supervise the user performing the above acts immediately. As a study for solving the above problem, there is the study of Policy Based Network Management (PBNM). This is the scheme for managing a whole Local Area Network (LAN) through communication control for every user. In this PBNM, two types of schemes exist. As one scheme, we have studied theoretically about the Destination Addressing Control System (DACS) Scheme with affinity with existing internet. By applying this DACS Scheme to Internet system management, we will realize the policy-based Internet system management. In this paper, to realize it, concept of the Internet PBNM Scheme is proposed as the final step.
