Recently, the small sized wireless terminals have problems of processing of large sized file because of the trends of a small sized terminals and a large sized files. Moreover, the web servers or the file servers have problems of the overload because of the concentration with many number of files to the them. Also, There is a security vulnerability of the data processing caused by the processing with a unit of the independent file. To resolve the problems, this paper proposes a new scheme of fat splining distribution using the P2P networks with the mesh topology. The proposed scheme is to distribute blocks of file into any peer of P2P networks. It can do that the small sized wireless terminals can process the large size file, the overload problems of a web or file servers can solve because of the decentralized files, and, the security vulnerability of the data processing is mitigated because of the distributed processing with a unit of the blocks to the peers.

It is required that information sharing and integrated management between roads and underground facilities because there are so many possibilities to happen unexpected accidents. But if there are road excavation work happened, work agency should ask fer other facility information to the facility management company. In the case of local government, it is increasing that the needs for the development of roads and underground facilities management system and information sharing because digital map generation(1/1,000 scale) completed. In this study, as a way of integrated management and information sharing between roads and underground facilities, centralized system based on internet web technique and decentralized system based on closed network technique between the local government are considered. And for the development of information sharing system, action plan and considering points are proposed.

Telecommunication network are becomming bigger and more complex. Its difficult to manage efficiently the networks, because these networks usually have heterogeneous and inompatoble compinents. Nevertheless, current approaches to network management have focused on centralized managementstrategies based on client-server architecture. These approaches have resulted in much weakness in the real-time management, the service extensibility, and the network scalability. In thispaper, we applied the mobile agent technology to solve the above problems. Jave is a promising technology for developing mobile agent system. But, there are several problems like the service extensibility in using the Java. To solve these problems, a new approach using digital signature is suggested to authenticate mobile agent in network management environments. This approach can solve the conflict between security of the system and extensibility of the mobile code. Moreover, the system suggested in this paper show the decentralized and flexible network management solutions.

Focused on the performance of interactivity in the appreciation of media art, this study is associated with the continually changed art texts and a participator's physical reactions to savor the art. Digital works of art emphasizing interactivity usually decentralize and disperse the responsibility and the central role for creating and producing the art works. Proper procedure of the work is generated by actions such as clicking the mouse, controlling the joy stick or actual movement of anticipators' bodies. The art works are influenced by participators' interactivity, which makes the leading roles and the responsibility for creating art scattered and divided. These features are similar with those of the 'Rhizome' which Gilles Deleuze(1925~1995) and Felix Guattari(1930~1992) have discussed. In their argument, 'Rhizome' is an interval or being 'between', which keeps changing. 'Rhizome' is a state in which the individual and the work of art never reach the conclusion, only a phenomenon of eternally altering. Like 'Rhizome', this sort of art work has the decentralized system, opens for several directions, and activates the system which is changeable as linked items increased or decreased. These works stimulate the individual to perform and act while appreciating the art piece. In terms of processing and preceeding, interactivity is the important equipment and catalyzer. Through these procedures, the pieces can be the 'floating work of art' combined and condensed with the whole participators' reactions. The 'floating work of art' is neither the expression of an individual nor that of one particular group. Multidimensional influence of the web is the web which is constantly reorganizing and producing in its connective state. This connective state is activated by interactivity. The Rhizomatic system embodies the floating work of art process. Due to each individual perceiving art in individualistic terms, there is no dominating powers or central points. I regard this art works possessing above traits as the work of art with Rhizomatic system. The work of art with the Rhizomatic system is embodied through interactivity and because physical action activates the process of appreciation, a participator can actually experience and practice the philosophy. Ultimately the Rhizomatic speculation occurs during the interactivity of appreciating the Rhizomatic art pieces. The Rhizomatic system penetrates into the intuitive area beyond our recognition and thoughts, as we are engaged in the connective process. With the methods and manners of interactive art, we can possibly reconsider the system as a tool in which the participator is directly able to link experience and theory to the philosophies of Deleuze and Guattari.
