  • Internet-based client/server architecture of Contents Delivery System suffers from frequent disconnections and security treats caused by dependency of the server or overload. But, We reached the limit to the increase of the server because a contents quality enhance and Internet user explosively increase. Therefore, a P2P based computing methods are used for sloving these issues. In this paper, We implement and design the Education Content Delivery System for cyber education system using idle Computing Power in P2P computing to share computing resources. We implement not only Internet infrastructure but also satellite infrastructure system, and designed to transfer real-time or non real-time contents.

  • This study compares choice of contents genre between mobile VOD service users and landline internet VOD service users. Overall, males showed a higher rate of VOD usage than females and a variety of contents were used for entertainment, programs and mood alteration. In addition, a higher frequency of VOD usage showed a higher rate of VOD usage and also resulted in higher level of satisfaction. Also, the quality of landline internet VOD service showed to be higher than mobile VOD service. This suggests that programs for mobile VOD needs to be developed as well as a more open and simple rate system. In addition, subjects of this study showed to use VOD services mainly for entertainment purposes, suggesting that a variety of programs need to be developed in order to higher the level of satisfaction of its users.

  • This paper presents the practice of multitexturing in the Internet for enhancing the image quality of 3D contents, where the attributes of objects such as textures are dynamically changed. We explain the empirical results of realizing the X3D nodes related with multitexturing in the recent X3D viewers, and discuss the directions for upgrading X3D viewers that satisfy the user requirements and the advanced graphics accelerators.

  • In recent years, various contents traffics are increasing according to the various internet connectable devices which have become contents provider. Because these contents traffics show different pattern from previous one, many researches for efficient contents delivery system are in progress. CCN(Contents Centric Network), one of the representative research subject, has inter operation problem with a current network because it has clean-state architecture. In this point of view, this paper suggests the SaNA(Service adaptive Network Architecture) for efficient contents delivery when it inter operates with current network architecture. SaNA is a convergence system which can be gradually applied to current network using CCN and SDN(Software Defined Network) which are core future internet technologies. Appling this system on the contents delivery service, it can increase the network bandwidth utilization by two times and decrease the contents delivery time by 1.7 times.

  • Purpose: The purpose of this study was to develop an integrated internet addiction prevention program and test its effects on the self-regulation and internet addiction of elementary students who are at risk for internet addiction. Methods: A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants were assigned to the experimental group (n=28) or control group (n=28). Contents of the program developed in this study included provision of information about internet addiction, interventions for empowerment and methods of behavioral modification. A pre-test and two post-tests were done to identify the effects of the program and their continuity. Effects were testified using Repeated measures ANOVA, simple effect analysis, and Time Contrast. Results: The self-regulation of the experimental group after the program was significantly higher than the control group. The score for internet addiction self-diagnosis and the internet use time in the experimental group were significantly lower than the control group. Conclusion: The effects of the integrated internet addiction prevention program for preventing internet addiction in elementary students at risk for internet addiction were validated.

  • In recent years, the number of users who are actively express their opinions about Internet articles is more and more growing up, as the use of cyber community such as weblog or Internet discussion board increases. In fact, it is not difficult to find an article with hundreds of comments in famous Internet discussion boards. Most of the weblogs or Internet discussion boards present comments in the form of list and do not yet support even the basic operation such as searching comments. In this paper, we analysed large sets of comments in Internet discussion board named AGORA. It was found that from the result that the distribution of comment writers follows power-law. So we suppose a new search structure of comments using skip lists. The main idea of our approach is to reflect the probabilistic distribution properties of the commenters following the power-law to the data structure. Our empirical results show that the proposed method performs more efficient in searching the nodes with fewer number of comparison operations than logN, which is the theoretical time complexity of general indexed structure such as B-trees or typical skip lists.

  • The study aims to look into relations between internet portal images and long-term orientation for continuing growth in the internet portal market with intensifying competition. In detail, the study aimed to identify the effect of the Internet portal image on long-term orientation and the relationship between satisfaction and the intention to recommend. As a result of an empirical analysis, the attribute of the image evaluation of the Internet portal sites was deduced to be a factor which included the affordances of information, entertainment and additional services, customer services, and convenience. All the four areas were found to significantly affect long-term orientation. Specifically, the affordances of information and entertainment and additional services were shown to be the most influential. In addition, the finding turned out that long-term orientation affected significantly consumer satisfaction and recommendation intention, and the satisfaction of relative portal had a significant effect on recommendation intention. These research results are supposed to be useful basic data for establishing competitive strategies of differentiated Internet portals in the market.
