  • The purpose of this study is to provide basic data for school health computerization by investigating the nurse teacher's attitudes toward school health computerization. For this study, the questionnaires were given to 559 nurse teachers from 3. March to 17. March, 1995. Among them, 338 were returned and included for the analysis. The results of the study were as follows : 1. In general characteristics, the results showed average of 38.6 years in age ; and average of 11.1 years in education experience. In distribution of school, the result showed 47.0% in elementary school, 30.5% in middle school and 22.5% in high school ; 75.4% national and public school vs 26.4% private school. 2. In attitudes of computerization, the score was varied from 19 to 76 point. The attitudes was generally positive with the average of 60.23±7.63(SD) score. The respondents are willing to participate in computer education(the highest score, 3.69), they worry about electromagnetic waves by computer (the lowest score : 2.30). 3. 92.6% of the respondents want to participate in computer education. The major reason the respondents have not yet learned computer is that they had little chance to learn. While 58.0% of them answered that they had an experience of computer use in school health works, few schools had computer in dispensary. In computer use, nurse teachers in public school have more experience than ones in private school. Word processing was the major function that the most respondents can do(62.7%). They answered that they have little knowledge of computer (84.0%). 4. Computer can be utilized in school health works as follows in order : message from school to home, reports, annual plan and statistics. 65.4% of them answered that computer can be used in 10 items of 13 items. 5. The attitudes of computerization showed differences in the following variables career, age, existence of computer in school health clinic, experience of computer use, intention to participate in computer education, computer knowledge, frequent computer use, ability of computer use, school health computerization areas, experience of computer education. Among there variables, age, existence of computer in school health clinic, intention to participate in computer education, ability of computer use, school health computerization areas showed significant explanation(28.3%) for the attitudes of computerization in multiple regression analysis The younger. the higher degree of intention, the more functions they can perform, the more school health computerization areas, and the more computers in school health clinic, the more positive attitude on school health computerization. In conclusion, to achieve the successful computerization of school health works, the positive attitudes of nurse teachers should be encourged for school health computerization. For this purpose, the chance of computer education should be given as many times as possible. And administerial as well as financial support are essential for enlarging the knowledge and ability of computer.

  • Redundant Programmable Logic Controllers are used in practice with the aim of achieving higher degree of availability or fault tolerance. In the paper a proposed Multiplex-PC is controled for fault tolerance design. In order to select a Different-Vender by a Supervisor computer, a Multiplex-PC is designed by TCP/IP internet protocol[1]. Because TCP/IP internet protocol can not connect to CPU. We use TCP/IP internet protocol to join CPU. We have to use TCP congestion control to select Different-Vender [4]. The reliability of the fault tolerant is measured with MTBF(Mean Time Between Failures)[3].
