In this paper, we propose a new minimum resources allocation algorithm for optimal design automation. In the proposed algorithm, the operation are allocated to functional units so that the number of interconnection wires between functional units can be minimized. The registers are allocated to the maximal clusters generated by the minimal cluster partitioning algorithm. Finally, the interconnection is minimized by removing the duplicated inputs of multiplexers and exchanging the inputs across multiplexers. The efficiency of the proposed allocation algorithm is shown by experiments using benchmark examples.

Antimicrobial powder was made by exchanging silver ion on calcined oyster shell. On the purpose of application to water clarifier, bail-type media mixed with antimicrobial powder and $0{\sim}30%$ white kaoline were made. The sterilization effect, pore size distribution and zeta potential was tested to indicate the condition for the media of water clarifier. From these tests, it was confirmed that this media have an excellent sterilization power on $G^-\;and\;G^+$ germs. As the concentration of the exchanged silver ion increased, the surface charge density of the anions on the surface of the media also increased. The surface pore size decreased with the concentration of silver ion and 20% more white kaoline ratio. Consequently, mixing ratio of white kaoline would appear to indicate the optimun condition as media have sterilization power.

The tactical data-link is useful to exchanging automatic information and controling command in combat environment. This is a essential factor of interoperability in the future combat situation of network centric warfare. In a aspect of a weapon system development, Modeling & Simulation can save expense. HLA RTI is a standard communication protocol in M&S. So, we suggest that Link Simulator connect tactical data-link through RTI. This simulator has the interoperability between M&S and tactical data-link, the reusability through adabing M&S framework, and the wide usability by automatic engagement function.

Two hard sub-problems have emerged relating to the use of mobile agents for service management tasks. First, what is their impact on security, and second, how can they receive a flexible capacity to adapt to an open range of different environments on demand, without introducing trio stringent prior assumptions. In this paper, we present work towards solving the second problem, which is of particular interest to management software, because it typically needs to excert fine-grained and therefore particular resource control. We suggest a mechanism that reassembles mobile agents from smaller sub-components during arrival at each hop. The process incorporates patterns of unmutable and mutable sub-components, and is informed by the conditions of each local environment. We discuss different kinds of software adaptation and draw a distinction between static and continuous forms. Our software prototype for dynamic adaptation provides a concept far exchanging environment-dependent implementations of mobile agents during runtime. Dynamic adaptation enhances efficiency of mobile code in terms of bandwidth usage and scalability.

China and South Korea have effectively reached a free trade agreement. The deal now faces legal and parliament reviews in the two countries. We need to discuss the recommendations on XML conversion with UN / CEFACT electronic documents. To solve this problem of interworking between these standards, Two kinds of translation rules is proposed for exchanging to UN / CEFACT Tag smoothly. For development and distribution of electronic documents to be conformed to international standards, it is enough to have the role of international activities continue to supply part of the domestic industry and the trends in participation and international standard. Our principal focus is on facilitating national and international transactions, through the simplification and harmonization of processes, procedures and information flows, and so contributing to the growth of global commerce. The agreement with South Korea will be China's ninth bilateral FTA.

We designed a family of completely autonomous mobile robots with local intelligence. Each robot has a number of on-board sensors, including vision, and does not rely on global positioning systems The on-board embedded controller is sufficient to analyze several low-resolution color images per second. This enables our robots to perform several complex tasks such as navigation, map generation, or providing intelligent group behavior. Not being limited to playing the game of soccer and being completely autonomous, we are also looking at a number of other interesting scenarios. The robots can communicate with each other, e.g. for exchanging positions, information about objects or just the local states they are currently in (e.g. sharing their current objectives with other robots in the group). We are particularly interested in the differences between a behavior-based approach versus a traditional control algorithm at this still very low level of action.

This paper proposes the way to analyse XML docuements according to the element information. XML documents, which are becoming new standard for expressing and exchanging data in the Internet, don't have defined schema. It is not adequate to directly apply XML documents to the existing relational database or object-oriented database query language. Research on how to extract schema for XML documents and query language is going on actively For users' query, the results could be too many or too less. It is important to give the users adequate results. Our proposed analysis method can be reduced or extended to correspond to the users' query more flexibly.

This study is to clarify the actual conditions of school Facilities in the Rural Area. The aim of this thesis is to present the direction for Reorganization of school facilities. Research area was Uiseong, Gyeongbuk, the number of students decreased rapidly. And elementary, middle and high school facilities were surveyed. The results are as the follows; 1) After consider living zone, commuting distance, opinions of residents, it is advisable that the small size school(the number of students under 60) will be combined stronghold school. 2) In the case of relocation, first of all, should consider the characteristic of living zone, exchanging training programs between elementary and middle schools. 3) The closed school facilities will be used consistently as public facilities with priority consideration of environmental characteristic and users' demand.

In this study, in order to adapt various types of suspensions that is not possible for a passenger car, and to validate the effect of the design change of a suspension upon ride and handling characteristics of vehicle, the modular experimental vehicle, which makes possible to exchange suspension systems, has been designed and developed. In order to enable the assemblage between the modules, the experimental vehicle design is based on a space frame construction through finite element analysis. Moreover, the module frames and the brackets are designed are designed using three- dimensionalsolid modeler to check the interference between each part of a vehicle. The results of simulation and experiment are compared.

This paper presents an integrated but open product development environment for distributed and collaborative design. The web-based framework, called DOME, allows designers to build integrated models using both local and distributed resources, and to collaborate by exchanging services in a network-centric product development environment. Thus, an integrated model can be created while each participant focuses on his or her own area of expertise. A design problem model is created by connecting modules, which represent specific system components, analysis capabilities/software, disciplines, or organizations relevant to the problem. The modules interact with each other using service exchanges based upon the CORBA standard communication protocol. The goal of this framework is tall provide the ability to rapidly construct integrated design problem models to facilitate collaborative design work, improve product quality and reduce development time. Ultimately, it should allow specialized engineering applications and design problem models to operate under a common design environment.
