인터넷의 활성화로 멀티미디어 콘텐츠의 저작권 보호에 대한 필요성이 점차 증대되고 있다. 본 연구에서는 디지털 워터마킹 기술을 이용하여 사용자 레벨에 따라 차별화된 콘텐츠 서비스를 제공하여 저작권을 보호할 수 있는 새로운 기술을 연구하였다. 여기서는 유료 사용자와 무료 사용자의 두 계층으로 분리하여 서비스를 할 수 있도록 하였으며, 유료 사용자는 고품질의 서비스를 무료 사용자는 저품질의 콘텐츠나 가시적인 로고가 들어가 있는 콘텐츠를 서비스 받도록 차별화할 수 있다. 디지털 워터마킹 기술은 콘텐츠의 품질을 높일 수 있는 정보를 은닉하는 데 활용된다.

전자도서관 환경에서 이용자가 원하는 바를 파악하고 이용자의 정보요구를 능동적으로 해결해주기 위해서는 이용자와 사서가 협력할 수 있는 상호작용 장치가 다양하게 마련되어야만 한다. 이 글에서는 전자도서관 환경에서 이용자와 사서의 상호작용에 대해 먼저 문헌에 보고된 사례유형을 확인한 다음 국내 연구도서관의 현황을 파악하였다. 이를 통해 국내에서 구축되는 전자도서관 환경의 효과적인 정보서비스를 위해 사서와 이용자 사이의 협력을 위한 상호작용을 활성화할 방안을 제시하였다.

In this paper planed Virtual Reality user interface that recently hot issue using MVLS(Multipurpose Visual Language System). Proposed system is planed for more with ease approach new type environment system. The point of this system is for more few the number of time of act to get want to result. That is easy build for Virtual Reality environment system that user so far, who did not experience. Also too, application to the environment through Multipurpose Visual Language System based, can be required to increase the case of user of existing applications, not only a simple application infrastructure Virtual Reality. This has the advantage of being able to under Virtual Reality condition the environment for the use of a wide range of applications such as view TV, video and other contents. By using the proposed system, the experience in virtual realities that have not felt during the general public to be able to easily and quickly, virtual reality or 3D Expected to can one step closer to the needs of general and industry.

The purpose of this study is to investigate alteration situation and user demand through the case study, to analyze the problems of the user participatory design, and to propose the improvement direction of user participation in the apartment housing. The results of this study are as follows: 1) The method of participatory design using a questionary must be improved with other communication methods between suppliers and users to adapt to the demands of users. 2) The range of menu and the time of participation must be varied to select various materials, colors, types of the interior finish and floor plan freely according to users. 3) Users have the positive attitude about the menu-option method and want to other methods of participatory design like the flexible housing method.

With the development of e-commerce and information access, recommender systems have become a popular technique to prune large information spaces so that users are directed toward those items that best meet their needs and preferences. In this paper, clustering technique is applied in the collaborative recommender framework to consider semantic contents available from the user profiles. We also suggest methods to construct user profiles from rating information and attributes of items to accommodate user preferences. Further, we show that the correct application of the semantic content information obtained from user profiles does enhance the effectiveness of collaborative recommendation.

GUMF (Global User Management Framework) that is proposed in this research can be applied to next generation network such as BcN (Broadband convergence Network), it is QoS guaranteed security framework for user that can solve present Internet's security vulnerability. GUMF offers anonymity for user of service and use the user's real-name or ID for management of service and it is technology that can realize secure QoS. GUMF needs management framework, UMS (User Management System), VNC (Virtual Network Controller) etc. UMS consists of root UMS in country dimension and Local UMS in each site dimension. VNC is network security equipment including VPN, QoS and security functions etc., and it achieves the QoSS (Quality of Security Service) and CLS(Communication Level Switching) functions. GUMF can offer safety in bandwidth consumption attacks such as worm propagation and DoS/DDoS, IP spoofing attack, and current most attack such as abusing of private information because it can offer the different QoS guaranteed network according to user's grades. User's grades are divided by 4 levels from Level 0 to Level 3, and user's security service level is decided according to level of the private information. Level 3 users that offer bio-information can receive secure network service that privacy is guaranteed. Therefore, GUMF that is proposed in this research can offer profit model to ISP and NSP, and can be utilized by strategy for secure u-Korea realization.

사용자가 지능 로봇을 효율적으로 이용하려면 사용자와 지능 로봇을 연결해주는 사용자 인터페이스를 설계해야 한다. 본 논문에서는 지능 로봇의 기능과 자율화 수준에 따라 휴대용 단말기 기반의 사용자 인터페이스를 어떻게 구성해야 하는 지 분석하고, 이를 기반으로 PDA (Personal Digital Assistant)나 스마트폰과 같은 휴대용 단말기를 이용하여 지능 로봇을 원격에서 조종할 때 필요한 사용자 인터페이스를 개발하고자 한다. 영상 기반 인터페이스를 이용하면 사용자가 로봇의 동작을 직접 보면서 로봇을 조종할 수 있고, 지도 기반 인터페이스를 이용하면 전송되는 정보가 줄어들기 때문에 정보 전송 지연시간을 줄이면서 사용자가 로봇을 조종할 수 있다.
