Media Contents Recommendation Web Service (service name 'mobodra') is a web service that analyzes media types and genre tastes for each user and recommends content accordingly. Users select some of the works randomly provided on the web when signing up for membership and analyze their tastes based on this. Based on this analysis, preferred content for each user is recommended. In this paper, we implement a content recommendation algorithm through item-based collaborative filtering. When the user's activity data or preference is re-examined, the above process is executed again to update the user's taste.

Recently, many consumer electronics manufacturers have produced 3D devices such as 3DTVs and 3D monitors as interests in a stereoscopic video service are getting increased. However, most of 3D services are focused on local storage or bandwidth guaranteed service since 3D stereoscopic video service require bandwidth more stable and larger. This property causes difficulties in seamless stereoscopic video streaming services under IP based open network environment that cannot guarantee quality of services. In order to achieve a seamless video streaming service the international standard organization MPEG (Moving Pictures Experts Group) has developed the adaptive HTTP streaming technology called as DASH (Dynamic Adaptive Streaming over HTTP). However, the DASH doesn't have obvious scheme which can express the two elementary video streams based service-compatible stereoscopic contents in one segment. Therefore, this paper proposes a scheme of efficient 3D adaptive streaming service based on the DASH, which covers not only frame-packing stereoscopic contents but also service-compatible ones. The 3D adaptive HTTP streaming scheme introduced in this paper is able to provide 3D contents with various qualities to user and also has benefit that single 3D content can be applied to a variety of devices.

This study aimed to identify the effects of contents, to find out the development approaches of promotion and contribute to increase the expectation on medical institutions and wills to use and improve the customer satisfaction on homepages of such medical institutions by analysis on the contents of hospital homepage. This research performed the frequency analysis, cross analysis, t-test correlation analysis, and multiple regression analysis and came to the conclusion. In accordance with the research results, since the university hospital homepages had more contents than the homepage of general hospitals and national and public hospitals, the university hospital homepage provided sufficient information to visitors and tried to satisfy the customers and activate the hospital promotion using the homepage contents. On the contrary, the homepage of general hospitals and national and public hospitals had insufficient contents and unique and differentiated contents were not sufficiently provided. On the basis of the results of this study, further study on the approaches to improve the contents of homepage of general hospitals and national and public hospitals will be of great help to activate the hospital promotion by increasing the average number of visitors and page views. Furthermore, it is required to make every endeavor for systematic management and operation and research on promotion using the homepage contents.

Recently, according to development of wired and wireless networks, contents production of user-defined changes a environment producing contents that it get out of manufactured contents offered by mobile telecommunication company. This paper propose a system proposing and registering a contents service provider of mobile telecommunication company for user-defined mobile contents production and transmission. We propose a system using web hosting service for user-defined mobile contents production and solution for system and transmission for contents production of a person and enterprises.

Our research team implemented and operated the system by analyzing the membership information and identifying the different preferences for each group and providing the results of the recommendation based on accumulated membership information and activity log data to the individual. The utilization log was followed up. We analyzed how many people use recommended services and analyzed whether there are any factors other than the personalization service algorithm that affect the service utilization of the system with personalization. In addition, we propose recommendation methods based on behavioral changes when incentives are given through analyzing patterns of users' usage according to methods of recommending services and contents that are often used based on analysis contents.

Recently IPTV that transmits multimedia contents in real time through internet, cable TV net and satelite net gets the limelight. But IPTV service that gives service to users by various media has a problem of not supporting user certification fully. This paper suggests a certification model which prevents getting access permission of IPTV service by sending illegal certification information by adolescent through integrating mobile communication technique with RFID(Radio Frequency IDentification) technique which is a key technique of Ubiquitous environment. This model performs the process of adult certification by keeping synchronization with user's certificaiton information that is saved in data-base of certification server and contents server after getting the system of class categorization in contents server to overcome disadvantage of simple adult certification system that is popular in the existing internet. Also, it adapts double hash chain technique not to down load illegally contents without the permission of manager even if an adolescent gets manager's approval key.

One of the particulars to be considered for providing wireless web service with PC web page is the hardware environment between PC and mobile device. It is because time cost is required in producing mobile contents to suit environment of the connected terminal. Therefore, server side should take account of response time and disk capacity of server. Response time is delayed by content conversion and disk capacity need to store various versions about one content. This paper suggests a pre-service and post-transcoding method to provide faster response time for a mobile terminal. The pre-service is to minimize response time by placing the top priority in servicing contents saved in cache as much as possible even if the quality of contents serviced to mobile terminal may be low. After pre-service is provided, the mobile content is transcoded for the terminal later. Performance level of method proposed was compared through experiment and the result of analysis was described.
