This paper presents development results of integrated operating program and its simulator for an inshore test miner. The inshore test miner drives on the seabed and collects manganese nodules. For operating the test miner, integrated operating program (IOP) is needed for remote control and monitor of the miner in real-time. However, it is hard to develop the practical IOP for the test miner system, because the system is big, expensive, and unique. So a simulator was developed as a test substitute in order to save time and to reduce cost. Using test results of the simulator, the IOP of the test miner was developed. The developed IOP consists of remote program, host program, monitoring program and database program. The operating program was developed using PXI and Labview of NI. The experimental results are presented to show the applicability of the developed program.

Korea Hydro & Nuclear Power Co. (KHNP) has developed and implemented the maintenance effectiveness monitoring (MR) programs for the operating nuclear power plants. The MR program is developed by reflecting design characteristics of the operating nuclear power plants to monitor the plant performance for improving the safety and reliability. Recently, KHNP has built a new nuclear power plant, and developed the MR program to establish the advanced maintenance system by reflecting unique design characteristics based on the OPR1000 standard model. So, the MR program developed in this study has another characteristics in comparison with the OPR1000 standard model, and we will verify the suitability of the MR program through evaluating initial performance of the plant. The safety and reliability of the new plant will be improved by developing and implementing the MR program.

When an escalator is developed or modified to improve its performance, estimation of dynamic characteristics of the escalator is required. But modeling of the escalator for a design purpose is very difficult and time consuming. Especially, it is very difficult for a designer to use the simulation model during design process because preparing a proper model takes time and also the designer needs to know how to use the simulation program. In order to solver these problems, a graphic user interface program that can predict dynamic characteristics of an escalator is developed for the designer. Since this program makes the necessary escalator model for simulation for itself, the designer does not need to know how to use the simulation program while design is in progress. In this paper, a designer oriented interface program is developed and an example is presented to show the effectiveness of the developed program.

In order tominimize fixing error of workpieces, circle, prismatic, sphere, cylindrical and sculptures types. Modification Rule by Indexing Table and Modification Rule by NC Program are developed for machining centers by using touch trigger probes. The Modification Rule by Indexing Table meas the alignment of workpiece to NC program through degree of freedoms of indexing table. The Modification Rule by NC Program is the alognment of NC program to workpiece ste-tp condition via the generation of NC progarm. A postprocessing module is alos developed for generating NC-part program(User Macro) to compensate for machining errors in end milling and boring processes. Developed method are verified by experiments.

Purpose: The purpose of the study is to develop a web-based program on child health care, and to identify the effect of the program on knowledge of, attitudes towards child health care, and health care practice in staff of daycare centers. Methods: The program was developed through the processes of needs analysis, contents construction, design, development, and evaluation. After the program was developed, it was revised through feedback from 30 experts. To identify the effect of developed program, onegroup pretest-posttest design study was conducted with 64 staff members from 12 daycare centers in Korea. Results: The program was developed based on users' needs and consisted of five parts: health promotion, disease and symptoms management, oral health, injury and safety, sheets and forms. This study showed that the total score of staff who used the program was significantly higher in terms of knowledge, attitudes, and their health care practice compared with pretest score (p<.05). Conclusion: These results suggest that this Web-based program can contribute to the child health promotion as well as can provide the staff with the insightful child health information. Therefore, it is expected that this program will be applied to staff of other child care settings for children's health.

Die-casting burr to casting process is removed by post-process for assembly and quality control of product. Though robot has been widely used for deburring job before. CNC exclusive machine is currently developed for high power, high speed machining and quick tool change. Deburring tool path with complex 3D curve type is defined to make out deburring NC program. But there is no efficient method to define it currently used methods with teaching probe on machine. In this study the efficient method to make out deburring NC program is developed. 5-axis digitizing machine is used to receive data of deburring path. And the post process for NC program generation is developed in consideration of the machining conditions. The developed system is not dependent on the skill of operator and has the advantage to maintain the flexibility of job to modify NC program due to the wear of tool and aging of the die casting.

The purpose of this study was to review the literatures on designing and developing the CAI program and to develop the middle school students’CAI program for tutorial and instructional game. For these purposes, the learning and instructional theories and the developing phases and strategies for the program were reviewed to design the CAI program. And then the developing unit was selected and the CAI types and the developing direction were set according to the analysis of the CAI programs and related literatures on home economics teaching, The four phases-analysis, design, development, and formative evaluation-were carried out in this study. The results of this study are as following: 1. The CAI porgram was developed on health and food life units. The program contains 12 classes on health and food life in two floppy diskettes. It consisted of total 9,000 lines and 76 frame and takes two hours to study this program. This program could be used in educational computers an could be utilized for unit learing tutorial. It was composed of three parts-unit learning, finding maze, and finding food. In the unit learning part, the learning contents in health and food life units were structured and presented. In finding maze and food part, the basic and the applied problems were presented with game. The characteristics of this program were as followings: (1)This program was able to bring learners’motivation due to the strategies of tutorial and instructional game and they can interestingly learn the program for themselves. (2) The learner could practive the learning contents repeatedly and unit learning while playing the gaming, (3) The learner himself can review and supplement the learning contents without teacher’s help. (4) This program was developed to unit learning on health and food life, on the other hand so far many CAI programs for home economics teaching were developed for studying separate learning units. 2. To effectively utilize this program, the guide book for the student and the teacher was developed. It contained method of using the program, introduction of the program, review of the program, the program objectives, the learning contents, and the keys to progress the program.
