There have been researches into digital Watermarking technology or Fingerprinting vigorously to safeguard Protective rights for knowledge and poverty for digital contents. DRM(Digital Rights Management) is not only Protective rights for knowledge and poverty, but also management and systems that are necessary to put out, circulate and use for contents. This paper proposes two kinds of ideas. One is protecting contents from illegal acts such as illegal copies when the contents are in the process of circulation. The other is the protocol that can give users convenience. Hidden Agents are used so that contents are protected from illegal copies and illegal use in the contents and cuts off those illegal acts. The Agent will be installed without any special setup. In addition, it can replace roles of Watermarking as a protection. Therefore, this paper shows the solution of illegal copies that happens frequently.

In this paper, we present the design and implementation of new execution environment named Customizable Architecture for Flexible Execution Environment(CAFEs) that supports the mechanism of protocol customization and service referencing. We introduce a new concept as micro protocols and active services to enhance software reusability. Micro protocol represents a specific algorithm or functionality of existing network protocol and the active service is in charge of binding legacy application and releasing the active network oriented services. The pro-posed active network execution environment is made up of three parts, virtual network system, protocol and service manager, event engine. First, the virtual network system is used to connect each active nodes using virtual network channels which are based on multiple existing protocol layers. Second, the protocol and service manager is responsible for composing micro protocols and active services to develop new network proto-col and service easily. Finally, the event engine is used to detect the automatic transition of system components using event delegation model. To verify the CAFTs, we have an experiment about the delivery of web contents which are suitable for the user's terminals in the wireless Internet environment. As a result. we are able to obtain the availability of developed execution environment.

The environment of education has been undergoing dramatic developments in recent years with the development of information technology such as digital information transfer, storage and communication methods. Education and training technology is constantly evolving and growing. Because we continually meet the new and interesting advances in our world. The evolution in education and training at a distance can be characterized as a move from traditional learning to u-learning. This paper concerns with the application of u-based education methodology for people with disabilities targeting to empower them. Instead of the classic educational support such as extended time to take exams, a reader and/or scribe to assist with exams and note taking services. In this paper, we introduce the definition of inclusion and disabilities which does not been fully understood what they mean and then possible implementing materials which can empower the students with disabilities with accomplishments. We would like to point out that we concentrate on the aspects of instructional science particularly related with inclusive classes.

On a huge space of information called the Internet, users can use a smart mobile web to get information on various intellectual fields and can access to various Medias such as personal blogs and social networking sites (SNS). This is why a vast amount of information on the web has been effectively managed and researched nowadays through a technology named Semantic Web. However, it still needs for an improvement for studies on searching for intellectual information, though it is enhanced to integrate variously spread information and search for intellectual information user-oriented. Thus, this study aims to research on searching information and knowledge spread around a knowledge-filled information space, which can improve credibility according to user-oriented logic.

Recently, the side effects from the online game is appearing to adolescent to serious level. This research studied the system to protect adolescent from excessive game usage, the system to limit an online game service connection at the midnight time. Namely we found at a shutdown system introduction of adolescent out about cognition, problems with the game poisoning and effects with shutdown system and alternative policy. The investigation results were as follows. First, only 17.5% of adolescent knew a shutdown system. Second, they were recognizing about the game poisoning seriously. Also the half degree thought them efficiently about a shutdown system introduction. The policy about a shutdown system introduction were as follows. First, public education is activate, and we must keep adolescent from exposing to private education in the entrance examine competition. Second, we need the thing to increase the conversation time of the children with put parents to develop desirable family education program. Lastly, the supply must be achieved with leisure culture contents development of adolescent.

Recently, As the managing techniques of consuming method and transmission for the sharply increasing multimedia contents has been developed regardless of compatibility by each company, It is a serious obstacle to the development of the organized copyright techniques because nothing can be shared by each other. The MPEG committee under ISO established MPEG-21 framework for it and proposed the REL as the words taking care of copyright and standardized them. However, there seemed to be some problems that special knowledge such as Schema defining the structures of XML and REL should be necessary. Furthermore, There can be some obscurity when the authority of REL document and one of consumer side is different. Therefore, in this paper, we laid out and realized the copyright including consuming system to copyright and prove the REL documents more conveniently and RDD integration system using Web Services technology which can get rid of the vagueness of REL.
