A computer program for computing complex system reliability is described. The program is composed of three phases : Phase I program reduces all series, parallel and series-parallel components and subsequently obtains an irreducible non-series-parallel system. Phase II program enumerates all the possible paths from the source to the sink of the graph. Phase III program then computes system reliability based on the information obtained by the Phase II program. The program is based on a modified version of the algorithm published in [6]. An example of the use of the computer program is given.

A web-based program life-cycle management(PLM) system is introduced to implement the system engineering processes and to provide the development teaceability online. This information system aims for the realization of essential system engineering management techniques currently applied to the space launch system development program including management of configuration and data based on the work breakdown structure(WBS), WBS, bill of materials and properties. The system enhances communication and gives access to the development data with relevant information such as data-to-data relation and approval status/history through the web, and preserve all of the development data throughout the program life-cycle. Further improvement of the system is planned to implement the program managrment pricesses and to provide integrated information useful for the programmatic decision making.

The purpose of this study was to utilize of the CAD system in pattern making process for women's bodice sloper, especially in education of the drafting. Accumark 540 System was used for this study. The drafting program was developed by the use of macro program in CAD system. The results from this study : 1. The Lim Won Ja's system of bodice sloper was selected in this study. The hand drafting of the system was arranged developing the macro program of bodice sloper. 2. The program consists of eight subprograms I sequence of the drafting order. In running this developed program, proper figure is drafted by inputing data. And the drafting process is automatically presented in interactive mode. 3. It has been developed to input the function of French Curve Ruler to increase the effectiveness of curved line treatment. The program can also be used in the curve part to present the manualy sensible function. 4. In case of education of drafting bodice sloper, the program provides the high accuracy, efficiency and a strong interest nterest in pattern making process by utilizing CAD system.

The simulation program which can predict major performances of the multi-type heat pump system was developed. In order to verify the simulation program, several experimental tests were performed under various recommended conditions. The experimental results show in good agreement with simulation results. The verified simulation program was used to analyze the system performance. The capacities and the COP＇s under the various indoor and outdoor conditions were predicted. Therefore, it may be concluded that the system simulation program developed in this study may be effectively used for the system design and the performance prediction of the multi-type heat pump system.

In this paper, we develop the image transfer remote maintenance monitoring system for hand held device which can compensate defects of human mistake. The human mistakes always happen when the worker communicate information each other to check and maintenance the equipment of the power plant under bad circumstance such as small place and long distance in power plant. A worker couldn't converse with other when in noisy place like Power plant. So, we make some hand device for handy size and able to converse in noisy place. The developed system can have improvement of productivity through increasing plant operation time. And developed system is composed of advanced H/W(hard ware) system and S/W(soft ware)system. The H/W system consist of media server unit, communication equipment with hand held device, portable camera, mike and head set. The advanced s/w system consist of data base system, client pc(personal computer) real time monitoring system which has server GUI(graphic user interface) program, wireless monitoring program and wire ethernet communication program. The client GUI program is composed of total solution program as pc camera program, and phonetic conversation program etc.. We analyzed the required items and investigated applicable part in the image transfer remote maintenance monitoring system with hand held device. Also we investigated linkage of communication protocol for developed prototype, developed software tool of two-way communication and realtime recording skill of voice with image. We confirmed the efficiency by the field test in preventive maintenance of plant power.

Purpose: The core of accreditation for nursing education is to improve the ability and quality of graduates through a CQI system based on outcomes. For program outcomes of nursing education accreditation criterion, it is necessary to understand the relationship among education assessment, objective and curriculum. Methods: The focus of this study was on program outcomes and the assessment. First measures for improving the general problems of program outcomes associated with the assessment system were stated. Detailed measure for practicing program outcomes, the assessment system and the assessment tool using Rubrics were discussed. Results: Detailed measure were established for practicing the program outcomes, assessment system and assessment tool, which makes use of rubrics, program outcome No 3 of the Korean Accreditation Board of Nursing Education. Conclusion: Therefore it is expected that the assessment system established in this study will allow universities to conduct program outcomes and assessment.

Software system is a hierarchical structure with collection of program units. Software system can import external packages globally or locally depending on the usage within a system. If the imported package is used globally, the soft-ware system can be influenced globally by any change of package and programmer's debugging time for the program maintenance will be greater. To solve these problems, it is desirable to use the imported package locally right on the usage point within the system. The model presented in this paper analyzed entity usage of package in structure of program, identified the usage level to obtain localization and provided information for restructure of the program to localize package usage. To obtain localization, it identified declared entities inside the imported package and analyzed the specification and body part of program unit to identify entities referenced from the imported package. The proposed model can be used to improve the maintainability of software system and contributed to reduction of programmer's debugging time in program maintenance.

Recently, with a progressive development of hardware of computer, the internet and network technology, the environment of construction varies rapidly due to increase the complex form in structure shape and system. With variations, the CAD system for design and products also varies from 2D system to 3D system. This study mainly deals with the methodology of automatic connection design of 3D CAD system, steel connection system (XSteel) using macro. First, using design program in the steel connection system, Xsteel, the joint connection macro will be made up and established the detail classes of design. The next, Database Program (Converter Program) related to the general structural analysis program (MIDAS) and the steel connection program (Xsteel) is constructed for data interface between two programs. From this study, if the merits of 3D CAD system and converter program are utilized well, it is expected that the time needed in modeling and the amounts due to material loses decrease gradually.

We demonstrated micro-scale conducting polymer patterning based on a selective surface treatment. A substrate with a patterned photoresist was immersed into OTS (Octadecyltrichlosilnae) solution. The protected substrate areas were hydrophilic after removing the PR resist, where a conducting polymer solution was coated selectively by spin-coating method.
