Failover subsystem of computer consists four modes In this paper, These modes will be discussed in more detail. - dual computer mode - failover mode - single computer mode - standby synchronization mode we have suggested the method of dual/redunancy configulation of server computer. Failover is activated by the standby computer, active computer receives a failover request across the inter-computer link immediatly. The active computer controls the scada system and maintains the current state in it's data base and channel system safety.

Interaction through communication plays critical role in the mathematics learning in the sociocultural perspectives. The communication make the students construct shared knowledge, and also plays a role of mediation in making meaning. So, we have to consider sociocultural eprspectives in design of the mathematics leaning using computer. While Computer Assisted Instruction was the one-directional teaching program which proceed from computer to students, mathematics leaning using computer in the sociocultural perspectives have to consider two-directional instruction that proceed from computer to students as well as from students to computer. This interactional activity is the critical thing in the mathematics learning using computer.

This paper proposes and sketches out a new parallel architecture of transputer-based pyramidal parallel array computer (TPPAC) used to process computationally intensive problems for geometric processing applications such as computer vision, image processing etc. It explores how efficiently the pyramid computer architecture is designed using transputer chips, and poses a new interconnection scheme for TPPAC without using additional transputers.

Recently, self-efficacy is one of the critical constructs that have been found to influence human decisions about behavior selection and the performance associated with the selected behavior. The construct has been widely adaopted and tested in the fields of social psychology and/or other behavioral sciences. In information system field, however, it has been hardly studied, although computer self-efficiency could have been an important factor explaining and predicting human computer usage behaviors. From this perspective, main proposes of the study are : (1) to develop a measure of computer self-efficacy, 2) to identify the factors influencing self-efficacy, and 3) to reveal the relationship between self-efficacy and computer usage behavior. By reviewing the literature, past experience, others'use, encouragement by others, and anxiety are selected as the factors influencing computer self-efficacy. Four hypotheses concerning the relationship between each of the variables and computer self-efficacy are tested by LISREL. One more hypothesis about the relationship between computer self-efficacy and computer usage is also tested. The results show that computer self-efficacy is significantly influenced by computer ansiety, encouragement by others, and computer experience, and that it is closely correlated with computer usage behavior.

It is time to put our top priority on the computer education to cope with rapid chage in technology and expansion of information. With 6th educational reform plan, from 1995 computer courses will be offered as elective subjects in the most of middle schools. However, detail planning for training of computer courses will be offered as elective subjects in the most of middle schools. However, detail planning for training of computer teachers and providing facilicles for computer education hasn't been adequately prepared yet, This will bring about confusion in computer education. The purpose of this study is to propose how to renovate the ordinary classroom into computer classroom. Followings are the suggestions for the educational specification for the renovated computer classroom for middle school in the urban area. 1) Purpose of computer classroom, 2) Size of computer classroom, 3) Curriculum design and class hour, 4) Facilities, 5) Environments, 6) Equipment and media(lighting and electric system, acoustical treatment, cooling/heating and ventilation system), 7) Activity area(Teacher workstation, Student workstation, Support area, Display surface). For the promotion of computer education, the legal, financial and administrative supports by concerned authorities should be established ahead of discussing the contents of computer education.

7차 교육과정이 시작된 지 벌써 5년이 지났지만 기대했던 것만큼의 성과를 얻지 못한 채 여러가지 문제점이 드러났으며, 빠르게 발전하는 컴퓨터 기술에 교육과정이 효율적으로 대응하지 못하고 있다. 지금까지 중등학교 컴퓨터 교육의 일반적이고 총괄적인 문제점은 많은 선행 연구에서 제시되었다. 하지만 일선 학교 현장에서 수업을 담당하는 교사와 수업을 받는 학생들이 느끼고 가졌던 여러 가지 컴퓨터 교육의 세부 문제점들을 정확히 조사하여 앞으로의 컴퓨터 교육의 정책에 반영해야 할 필요성이 제기되고 있다. 본 연구에서는 지금까지 선행 연구에서 제시한 컴퓨터 교육의 일반적인 문제점들을 바탕으로 실제 중학교 현장의 정확한 실태와 교과재량으로 선택한 컴퓨터 교과의 실질적인 문제점을 컴퓨터 담당 교사와 학생들의 설문 조사를 통하여 객관적으로 분석하고, 이를 토대로 중학교 컴퓨터 교육의 개선 방안을 제시하였다.
