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.

This study is to investigate the 7th curriculum of computer education and its implementation by analyzing 1. computer H/W distribution status, 2. number of schools to select computer subject, 3. professional competency of computer teachers, 4. job loads for computer teachers, 5. instructional materials used for computer subjects, 5. problems of curriculum implementation, 7. confronting instructional problems. Data was collected from the survey to 191 teachers who are from teacher in-service programs in July, 2005, in-depth interview and national educational statistics. Suggestions for the curriculum revision were made.

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.

5 years are passed since the 7th National Curriculum of Education began. The curriculum didn't get successful outcomes, rather brought about several problems. Especially, the computer curriculum didn't effectively deal with fast developing computer technology. In present, the general and overall problems of middle school computer education suggested in many previous researches. After we investigate general computer education problems which computer teachers and students are felt, we must try to reflect the results in computer education policy. In this paper, on the basis of general computer education problems suggested by previous researches, we absolutely analyzed the teacher's and student's question results about correct situation of middle school, and suggested improvement methods of middle school computer education.
