  • This paper presents the development of a microcomputer-aided design program for a SISO control system. The program has been written in GWBASIC language which is suitable for Intel 80861 CPU with 640KB memory. By utilizing this program, sampling time, the number of bits for the A/D and D/A converter, and the stability for the digital control system can be determined. To demonstrate the utility of this program, a microcomputer controlled precision temperature control system has been employed as an example.

  • A study is the selection of optimum forming condition for RP system. We develop the Automatic design program for machine element using visual LISP program in AutoCAD. Automatic design program reduces the required time for feedback between design and manufacturing of workpiece. Also we investigate the relationship between circularity of 3D solid model and circularity of rapid prototype using RP system and we will find optimum forming condition in RP system.

  • In this research an induction motor vector control system was developed using Simulink and RTW(Real Time Workshop). On the Simulink window, control system is designed in the form of block diagrams, program codes are produced automatically with the RTW, then c compiler compiles the program codes. With this automatic real time program producing mechanism rapid prototyping is realized without the time-consuming manual program coding procedures. To show effectiveness of the proposed designing scheme a DSP-based induction motor vector control system was constructed and implemented

  • The multi type heat pump system may provide more energy savings and better environmental conditions than the single type heat pump system may do. In order to design a multi type heat pump system, it may be recommended to develop the system simulation program, which can predict the characteristics of the system such as unit capacities, power consumptions, and system COP's. In this study, the steady state simulation program of the multi type heat pump system was developed. The results from the simulation program were compared with those from the experimental tests which were performed in the environmental chamber, Cooling tests show 3.11% and 0.94% of error in capacity and COP, and heating tests show 3.30% and 1.90% of error in capacity and COP, respectively. Therefore, the steady state simulation program developed for this study can effectively be used for the design and the performance prediction of the multi type heat pump system.

  • In recent years, the design has formed and operated convergence education in conjunction with many other academic fields, and ABEEK also encourages the participation of convergence engineering programs. The purpose of this study is to require design and software convergence major to operate program that accord engineering education certification criteria to develop a program outcomes evaluation system and examine its validity. The program outcomes evaluation system was developed in accordance with development research methods and procedures. As a result, developed evaluation system program outcomes for convergence-based program outcomes: convergence ability, creative thinking ability, entrepreneur ability, and design ability. Finally, it revised and supplemented them through expert validity examine. Expert validity review included 9 experts in engineering, IT engineering, education technology, and design. The validity, usefulness, intelligibility, universality, and explanatory power of the evaluation system were reviewed. The results of this study are expected to provide practical tools for operating ABBEK of convergence programs between design and engineering.

  • In this study we developed a CCD camera image capture program for Mobile Mapping System. Especially, two high resolution color images could be captured and saved simultaneously through this program to apply digital photogrammetry. Program developed in this study could be used more effectively on the 3D positioning of road facilities, the state understanding of maintenance and etc. using Mobile Mapping System with GPS-IMU. Most programs currently developed and used are for the panchromatic images. But, newly developed program is for the high resolution color images. Therefore newly developed program could expand application field of Mobile Mapping System widely, and users. This research can improve the usability of 4S' products with stable and reliable.

  • In this study, an intermediate model is presented as a new method for development of a parametric simulation program. This model enables us to analyze effectively the static and dynamic structure of a real production system. The static structure of the real system can be modelled in an entity-relationship diagram and the dynamic structure of the real system in a Petri net. The intermediate model consists of an entity-relationship diagram and a Petri net. Using this intermediate model man can not only reduce the time and cost for simulation program development, but also increase the modelling reliability of the developed simulation program. To show the usefulness of this intermediate model. the intermediate models for two production subsystems, manufacturing sub-system and transport subsystem, are set up.

  • This study addresses the question of how to design the research system for national R&D programs that aim to promote creative innovation. This paper attempts to analyze the case of Creative Research Initiatives(CRI), a new national R&D program recently launched by the Ministry of Science and Technology of Korea. CRI is a strategic program intended to shift the national R&D paradigm from imitative innovation to creative innovation. The key features of the research system of the program include: a research-centered system, long-term research funding, the sunset approach, a dynamic and flexible research organization, and a centralized research system. This paper suggests theoretical rational of these key features based on the literature review on creative innovation. Based on an analysis of the results of implementing the CRI in 1997, this paper also examines how the research system design is reflected and embodied in the program implementation process. Finally, policy implications and future research directions are also discussed.

  • This paper reports that a DDD system controlled by Stored Program Control(SPC) method was constructed and performance testresults were presented using a microprocessor instead of using conventional Wired Program Control(WPC) method. It is shown that the system was designed using a STD O/G unit which has only Point to Point(PTP) access function due to selector driving method as a O/G repeater of this system without any modification. When the system is adopted to a toll exchange system for medium and / or small city, it is expected that the system can be made with small size, high reliability and no use of conventional selector switches. It is also predicted that variation of communication route can be easily realized by simple program modification.
