Multi-resolution modeling(MRM) is required when simulating objects in variable resolution and can be applied for interoperating systems, which simulate objects in fixed resolution. However, most interoperation middleware do not support MRM, so participating models must handle several issues to simulate MRM system. In this paper, we propose an interoperation system, which is composed of several different resolution models, based on the High Level Architecture and Run-Time Infrastructure(HLA/RTI). In the proposed architecture, each model participates to a HLA federation through MRM adapter application, which supports data resolution conversion and HLA services while communicating with the model. MRM adapter application can be implemented based on an MRM adapter, and an adapter application development tool is proposed to support developing the application. Using the tool, developers can easily implement data resolution conversion component plugged-in HLA adapter. A case study is implemented in the proposed MRM system, and shows that models of different resolution works successfully with dynamic resolution changes.

Purpose & Method: Based on a large amount of research concerning the recognition of local residents in an era of an increasing number of multi-cultural families, this study aimed to provide fundamental data for program development and policies. As well, the data was stratified based on understanding of multi-cultural society, recognition of multi-cultural families, and social and economic adaptability of multi-cultural families. Result: The available literature supports the view that an understanding of a multi-cultural society and recognition of multi-cultural families encourages an emphasis on maintaining ethnicity and respect for diverse cultures. Parental approval for friendships with members of multi-cultural families tends to be encouraged, although there is still resistance to marital ties with such families. The literature indicates that immigrant women participate in economic activities of their adopted locale and adapt to the new societal structure. A positive correlation between recognition and interests in social and economic adaptiveness was apparent. Conclusion: Findings of the study suggest that complement, development, and application of realistic programs and institutional policies are required to understand multi-cultural families and establish a multi-cultural society. Ongoing research will be valuable in resolving outstanding questions and clarifying political alternatives.

In this paper, we applied the high-performance PGAP(Parallel Genetic Algorithm Processor) to recognizing rotated pattern. In order to perform this research efficiently, we used Multi-PGAP system consisted of four PGAP. In addition, we used mental rotation based on the rotated pattern recognition mechanism of human to reduce the number of operation. Also, we experimented with distinguishing specific pattern from similar coin patterns and determine rotated angle between patterns. The result showed that the development of future artificial recognition system is feasible by employing high performance PGAPS.

In order to model the Group Technology Problem three formulations are used, that is, generally the following formulations are used: (1) Matrix formulation, (2) Mathematical programming formulation, (3) Graph formulation. In the case of Matrix formulation, it is difficult to discribe the situation using the multi-job machine. But this paper proposed the model of Group Technology using the multi-job machin, taking the method of making practical application of principle of similarity coefficient.

The application of SRM(Switched Reluctance Motor) is dramatically increasing due to a simple mechanical structure, high efficiency and a good high speed characteristics. To control high conduction ratio in motor operation and regenerative voltage in the generator operation multi-level voltage control is effective. This paper proposes multi-level inverter to have a maximum conduction ratio of SRM. The proposed method is verified by experiments.

This paper presents a Multi-Agent system for setting and coordination of overcurrent protective devices in the distribution system. The simulation model shows its feasibility in which KQML is used for communication among agents. The proposed system could make it possible to keep the protection system in the optimal state all the time.

A new control scheme for the state space model of the robot system using the theory of optimal multi-variable structure is presented in this paper. It is proposed to optimize multi-dimensional variable structure systems for obtaining the required stabilizing signal by minimizing a performance index with respect to the state vector in the sliding mode. It is concluded the proposed variable structure controller yields better system dynamic performance than that obtained by using the only linear optimal controller inthat responses for a step disturbance have a shorter setting time, no matter what overshoot values and rising time.

기업의 전사적인 자원 관리(ERP)의 필요성이 급증하면서 이에 따른 광범위한 데이터베이스 관리의 중요성이 점차 부각되고 있다. 이러한 이유로 말미암아 데이터베이스의 확장 즉, Schema의 변화에 따른 데이터 베이스 접근을 위한 응용프로그램으로써 Multi-Tier 구조가 제시된 바 있다. 그러나 또 다른 시스템에 적용하는 경우 데이터베이스의 접근을 제 변경해야 하는 등, 여전히 많은 문제점이 드러나고 있다. 본 고에서는 이러한 문제점을 해결하기 위한 방법으로써 데이터 베이스의 Schema에 독립적으로 접근할 수 있는 새로운 Multi-Tier 구조를 제시한다.

Regarding the application of diagnistic technology using PD signal to power apparatus, it is necessary to discriminate the type of defect as well as to determine whether the PD occurs or not. In this research, PD characteristics of multi-defects insulating system were presented, the PD signals were detected from three kinds of electrode systems, IEC(b), needle-plane and CIGRE method II. To make multi-defect systems artificially, we combined three electrode systems and applied same test voltage simultaneously.
