  • LPM(Linear pulse motor) was developed as a prototype. In this paper, the design results of prototype and its dynamic characteristics are shown. The prototype was designed by using permeance analysis and the thrust value was also confirmed by comparing with the analysis results of the finite element method. To verify the performance of LPM. dynamic characteristics were measured. In slewing characteristic of the LPM, the thrust value of prototype LPM is higher than commercial level. A X-Y table was structured as a application of the prototype LPM. A controller and user's interface was also developed. By using this control system, the position error of X-Y table was checked. The repeat position error in linear movement was under than ${\pm}$ 100 micron.

  • In this paper we designed a prototype hybrid type linear pulse motor (HLPM) with single side stator structure for low cost. The measurement system which can get the motor characteristics of the HLPM was suggested. The static and dynamic characteristics of the thrust force are measured analyzed. And the microstep drive method is adopted and tested to the drive of prototype HLPM. The thrust waveform is measured respectively to know the differences of the thrust waveform between the microstep drive method and rectangular wave. From the experimental results, it can be confirmed that the repetitive ripple of the thrust force of the prototype HLPM is reduced by taking the microstep drive method.

  • The mathematical models of the Switched Reluctance machine system integrating the state equation of the phase current with the two dimensions finite element model of the machine are advanced, no matter what the topologies of the main circuit of the power converter and the control strategies are adopted in the system. Based on the mathematical models, the comparison of the simulated and the tested results of a three-phase Switched Reluctance motor drive prototype system are given. The simulated results of the prototype tally with the tested results of the prototype. It is shown that the mathematical models have the advantage in high precision.

  • This paper describes the forming of fine gear housing using RP system. In order to apply 3D model formed through CAD software to RP system, it is necessary of transforming 3D model into STL file format. Besides, when the same shape is formed repetitively, we must solve the program that the shape accuracy of prototype is irregular. Therefore, we will make an experiment on influence of 3D model, file transformation and prototype on facetres, AutoCAD system value. On the basis of experimental result, we will develop an automatic file transformation program for RP. In the final process, we will manufacture on a better prototype according to the experiment result of fine gear housing.

  • The work was aimed at realize the problem of seed processing . Solving this problem it was ascertained that the existing mathematical methods are reliable enough, but they are used practically very seldom. The work offers to use the expert system technology which allows to solve problems connected with practical knowledge of experts in the region of investigation effectively. The method of knowledge structuring and analizing as well as technique of knowledge acquisition which is necessary for realization of this technology are worked-out in the work. As the result applying the worked-out method the prototypes of the expert system (ES) are created : -ES " Sieves " ; research prototype for the sieve choice for the seed sorting machines -ES " Diagnostics " ; displaying prototype for the technological determination of action disrepair of seed sorting machines.

  • 토지정보와 건물정보는 부동산, 도시행정 분야에 있어서 가장 핵심이 되는 공간정보이지만 융복합 및 통합적인 활용이 용이하지 않아 통합정보서비스가 제공되기 어려웠다. 본 연구에서는 토지정보와 건물정보에 대한 통합정보시스템의 필요성과 정보 융합의 방법론, 통합시스템의 구축 방안을 제시하였으며 프로토타입 시스템을 개발하여 통합정보에 대한 활용 가능성을 제시하고자 하였다. 이를 위해 토지정보와 건물정보에 대한 관리 현황을 분석하였으며, 이를 바탕으로 토지 및 건물에 대한 다양한 공간정보와 속성정보 간의 매칭 및 융합 프로세스를 적용하였다. 융합된 토지 건물정보 DB를 기반으로 한 통합정보시스템과 기능을 설계함으로써 프로토타입 시스템을 구현하였다. 마지막으로, LX가 시스템을 운영하면서 부동산 및 도시행정 분야에 제공할 수 있는 정보서비스 사례들을 제시하였다.

  • Since the cost of a new product is determined mainly at the design stage, systematic tools to support the new product to be manufactured at the predetermined cost is very important for successful introduction of a new product. PDM is a tool to support engineers to integrate product data throughout the product development. In this paper, we introduce a prototype of PDM system which has a target costing function, where cost estimation is coupled with structured product data.

  • The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

  • In this study, we tried to develop the Web-GIS system prototype that will be able to effectively manage the nationwide flood prevention operations and to establish a framework that will be able to maintain the operation consistency. To achieve the study goals, we analysed current system of flood prevention operations, gathered related documents, had interviews with many government employees, and developed the Web-GIS system prototype. Also, we tried to present the benefit-cost analysis method using GIS technique that will be used to decide the priority order of the operation.
