The image communication system based on power line communication(PLC) that manages the status of workers in deteriorated. work environments such as high temperature and pressures as realtime is designed and implemented in this paper. The major design considerations for system design are such that the adaptation of simple architecture, simplicity of installation and movement, tolerances about high temperature and pressures, transmission of high quality image under various noise environments.

The purpose of this study is to provide design guidelines on office layouts to improve workers' concentration and communication behavior while supporting work processes. Among the present office types, benzene-type was preferred the most was providing better concentration. Regarding communication, link and benzene were preferred types. In present office types, workers were satisfied in communication more than concentration. To increase concentration level, acoustical privacy was indicated as the most important factor In conclusion, to support both concentration and communication in office, the team area should be divided into smaller sub-team areas. The sub-team areas may support interaction within a group while preventing unnecessary distraction. The major circulation of work process should be formed outside of the sub-team areas to provide concentration within the groups.

A satellite RF communication link is analyzed based on a simple fundamental equations by systematic approach in this paper. The number of variables related to a design and analysis of satellite RF link is often a dozen or more, thus it is a tedious and time-consuming task. With the given input data, the important parameters are calculated step by step and three communication characteristics such as communication channel capacity, carrier-to-noise ratio(CNR) at the satellite and ground station are analyzed. It gives very useful information to the system engineers for designing and analyzing the overall satellite communication system in the conceptual design phase.

In communication protocol design, it is important that design procedure is simple and result protocol must be correct. This paper presents a communication protocol synth-sizing algorithm, which enhances productivity of protocol design, using CFSM. CFSM is defined as extended FSM for representing protocol information and simplification. In this method protocol designer descripts only one communication machine with out error consideration using FSM, then two communication machine M' and N' are generated. And then transformation rules for error-recovery converts M' and N' to EM' and EN' which are logically correct.

In this paper, due to the congestion the radio spectrum, frequency bands are shared among the satellite communication system. Therefore for satisfactory we have to design and predict with reasonable accuracy the level of interference that might exist among them, Interference among the satellite communication systems depends on many factors such as climate, radio frequency, time percentage of interest, distance and path topography, propagation delay time. This paper suggest design method of Low-Orbit satellite communication and calculates the field-of view of satellite, for the communication era using LEO. In addition, performs performance evaluation on the basis of link margine.

The aim of this paper is to explore various ways to utilize critical thinking in engineering education. To this end, this paper, in the light of the relationship between critical thinking and the program learning performance of ABEEK, reviews engineering design education, engineering ethics education, and engineering communication education, which are major areas where critical thinking can be utilized in engineering education. As a result, it was confirmed that critical thinking skills, especially the elements and criteria of critical thinking, can contribute to the creative problem-solving process in engineering design education, the rational decision-making process in engineering ethics education, and the effective communication process in engineering communication education.

This paper presents a computing system, called MEDICOS. that enables Multidisciplinary Design Optimization (MDO) technology for engineering design on distributed environments. In MDO, various legacy softwares have to be Integrated, so dynamic configuration and seamless coordination between these legacy softwares must be supported. MEDICOS is designed to address these issues by the Linda shared memory model-based design and the agent-based wrapper technology. A prototype system for engineering designs is developed and tested with designing a super high temperature vacuum furnace.

오늘날 제품개발 환경에서 디자이너는 고유의 디자인 업무뿐 아니라 여러 기능부서의 의견을 수렴하고 통합, 조정하는 교량 또는 촉매로서의 역할을 요구받고 있다. 이러한 변화에 따라 디자이너는 제품기획에서 생산, 판매에 이르는 제품개발의 전 단계에 적극적으로 그 역할을 하지 않을 수 없게 되었다. (중략)
