In spite of the importance of nuclear power as one of major electric energies in Korea, the nuclear safety has become the most serious social issue in the operation of the nuclear power plant. In this paper, a virtual work simulation program was developed to predict exposure dose during radiation work in radwaste storage. The work simulation program was developed. using $Java ^{TM}$applet and VRML-virtual reality modeling language. A numerical algorithm to find the optimal work path which minimize exposure dose during the given work, was developed and exposure dose on the optimal work path was compared with that on the shortest path. Comparing with the shortest path for the given work, the predicted optimal path consumed longer work time by II% but reduced total exposure dose by 46%. The simulation result showed that the exposure dose depended on not only work time, but also the distance between the worker and the radiation source. The developed simulation program could be a useful tool for the planning of radioactive waste work to increase the radiation safety of workers.

The purpose of this study was to develop an optimal path planning program for autonomous speed sprayer in orchard. A digital map which contained coordinate information and entity information including height, width, radius of main stem, and disease of a trees was developed to build an optimal path. The digital map, dynamic programming and order-picking algorithm were used for planning an optimal path for autonomous speed sprayers. When this algorithm applied to rectangular-shaped orchards to travel whole trees, the developed program planned the same working path and same traveling distance as those of created by conventional method. But for irregular-shaped orchards, developed program planned differently and 5.06% shorter path than conventional method. When applied to create path for multi-selected trees, irregular-shaped orchards showed 13.9% shorter path and also rectangular-shaped orchards showed 9.1% shorter path. The developed program always planned shorter path than the path created by conventional method despite of variation of shape of orchards.

In this paper, our effort to apply 3-D Virtual Reality system for stereoscopic visualization of flow data is briefly described. This study is an extension of our previous and on-going research efforts to develop DATA(Data Analysis and Visualization Application) program, which is a data visualization program developed by using Qt as GUI development environment and OpenGL as graphic library. The program is developed upon the framework of object-oriented programming and it was originally developed by using Qt 3.3.3 environment. In this research the program is converted into a Qt 4.3.3-compatible version, and this new version is developed on Visual Studio 2005. And to achieve a stereoscopic viewing capability, two graphic windows are used to render its own viewing image for the lift and right eye respectively. These two windows are merged into one image using 3D monitor and the viewers can see the data visualization results with stereoscopic depth effects by using polarizing glasses. In this paper three dimensional data visualization with stereoscopic technique combined with 3D Monitor is demonstrated, and the current achievement would be a good start-up for further development of low-cost high-quality stereoscopic data visualization system.

알고리즘의 추상적 속성은 학습자의 동기와 학습 증진을 저해하는 요소로 작용할 수 있다. 따라서 학습자의 내적 인지 부담을 감소시키고 동기를 유발하기 위한 교수 학습 방법에 관한 연구가 필요하다. 본 연구에서는 전문계 고등학생들의 동기와 성취수준 향상을 위해 놀이를 통한 알고리즘 교수 학습 프로그램을 개발하였다. 개발한 프로그램을 적용한 결과, 놀이 중심 알고리즘 학습 프로그램을 수행한 집단이 전통적인 알고리즘 학습을 수행한 집단에 비해 학습동기와 학업성취 면에서 유의한 차이를 나타냈다. 이는 놀이와 같은 구체적인 활동 수행이 추상적이고 어려운 개념 학습에 긍정적인 영향을 준 것으로 해석할 수 있다.

Purpose: This study was to develop a screening model for identifying a high risk group of dementia and to develop and evaluate the web-based prevention program. Method: It was conducted in 5 phases. 1) Data were collected from dementia patients and non-dementia patients in a community. 2) A screening model of the high risk population was constructed. 3) The validity test was performed and the model was confirmed. 4) Four weeks-prevention program was developed. 5) The program was administered, and evaluated the effects. Result: The model consisted of age, illiteracy, history of stroke and hypercholesterolemia. The program was designed with 12 sessions, group health education using web-based individual instruction program, and 12 sessions of low-intensity physical exercise program. After the completion, their self-efficacy, and health behaviors in experimental group were significantly improved over those in the control group. The perceived barrier in the treatment group is significantly decreased. Conclusion: The screening model developed is very simple and can be utilized in diverse community settings. And the web based prevention program will encourage individual learning and timely feedback, therefore it can facilitate their active participation and promote health management behaviors at home.

The purpose of this study was to develop an Integrative Group Counseling Program to reduce depression, suicide ideation, and stress of high school students, and to examine the effectiveness of such a program. In order to evaluate the effectiveness of the program developed, an experimental group which was exposed to the program and a control group without exposure to the program were compared. The program was administered over eight weekly sessions, each session lasting ninety minutes. The subjects in this study consisted of twenty students. An experimental group and a control group were organized with ten students in each. For data processing, SPSS 16.0 was used to analyse statistical results. The Center for Epidemiological Studies-Depression Scale, the Suicidal Ideation Scale, and the Stress Scale were used in a pre-test, post-test, and follow-up test. The findings of this study were as follows : The treatment group exhibited a significant statistically decreasing degree of depression, suicide ideation, and stress levels in comparison to the control group. The results of the study indicated the effectiveness of this newly developed Integrative Group Counseling Program on reducing depression, suicide ideation, and stress levels.

Purpose: The purpose of this study was to develop a clinical practice nursing students' microbiology program based on the mastery learning model, and to evaluate the effects of the program on nursing students' knowledge, self-efficacy, performance, and satisfaction related to the nursing students' microbiology program. Methods: The program was developed by using the processes of the mastery learning model. The pre-experimental research design involved a one group pretest-posttest design. The setting was a university located in Incheon, Korea. A total of 130 nursing students participated in the program including a theoretical lecture, clinical practice, and formative and summative evaluation. Results: Using the program that was designed and developed, results for the total score of self-efficacy, knowledge, and performance in the post-test application were significantly higher than in the pre-test application (p<.05). The satisfaction of hand hygiene and disinfection/contaminated hand microbial culture and disinfection test received the highest ratings. Conclusion: The application of a clinical practice nursing students' microbiology program was effective, and can be expanded to other nursing students. Future research with other study designs was warranted in order to prove the effect of a microbiology program based on the mastery learning model.
