The purpose of this study was to evaluate the effects of Web-based nutrition education program for junior and senior high school students. Three materials, which were printed materials on Group I, WBI (Web-Based Instruction) leaflet on Group II and the web-based nutrition education program developed in the antecedent research, were applied for 564 students in 3 junior high school and 4 senior high school in Seoul during 4 weeks. Pre-test was done from October 21 to October 26, 2002 and post-test was done from November 25 to December 13, 2002. The statistical data analysis was completed using SPSS WIN (ver. 11.0) for descriptive analysis, t-test and ANOVA. According to the evaluation of effectiveness for web-based nutrition education program, nutrition knowledge, food attitude, food habit and nutrient intake were not significantly improved but positively. And on the evaluation of effectiveness for nutrition education program by materials, WBI was more effective educational materials than WBI leaflet and printed materials. Consequently nutrition knowledge, food attitude, food habit and nutrient intake were improved positively but not significantly using WBI, which was due to the instructional period of the only 4 weeks. Therefore long-term instruction should be required for effective nutrition program, as well as more WBI nutrition education program for high school students would need to be developed in the near future in that WBI was effective material on nutrition education.

When evaluating effectiveness of a government's supporting program, there is a tendency to simply compare the performances of the treated before and after the program or to compare the differences in the performances of the treated and untreated before-after the program. However, these ways of evaluating effectiveness have problems because they can't account for environmental changes affecting the treated or effects coming from the differences between the treated and the untreated. Therefore, in this paper, sequential applications of PSM and DID are suggested as a means to overcome those problems. It turns out that this approach enables us to eliminate self-selection bias and thus better evaluate effectiveness.

The objective of this study is to present a basis for the evaluation on the renewable energy dissemination program in Korea applying the outcome evaluation, one of the five types of evaluation methods of EERE, DOE, and the effectiveness indicator, which is suggested by IEA, OECD. The outcome evaluation quantifies achievements of program outputs and outcomes against planned time frame. We analyze the correlation coefficients between cumulative expenditure on the renewable energy dissemination program and each renewable energy deployment and the unit installation cost of several dissemination programs for the outcome evaluation. Meanwhile, the effectiveness indicator is calculated by dividing the additional renewable energy deployment achieved in a given year by the remaining mid-term realizable potential to 2020 in each source of renewable energy. The results show that correlation coefficients between cumulative expenditure and each renewable energy deployment are significantly positive during the implementation period of each deployment program. And photovoltaic energy, bio energy, and wind power energy show high effectiveness indicator.

The purpose of this study was to test the effectiveness of cognitive-behavioral therapy to prevent relapse of substance abuse. A total of 8 substance abusing adult clients participated in the program. All the clients were charged with substance use at the time of implementing the program. Two master's level social workers operated the program, which was implemented in a probation office in Seoul. This study included Beliefs about substance use, abstinence self-efficacy, and coping skills as dependent variables in order to investigate the effectiveness. Cognitive-behavioral therapy emphasizes the enhancement of these cognitive and behavioral skills to prevent relapse of substance use. Research hypotheses were partially supported. That is, clients participated in the program had more negative attitude toward substance use and had more effective problem-focused coping skills. Although a research hypothesis of the enhancement of clients' self efficacy was not supported, their mean scores at the final post test were lower than scores at pretest. This study suggests that more studies be needed to in order to confirm the effectiveness of cognitive-behavioral therapy with substance abusing clients.

The purpose of this paper is to analyze cost-effectiveness of a train simulator. The cost-effectiveness of training program is assessed by multiplying transfer effectiveness ratio (TER) by training cost ratio (TCR). If their product is less than one, the program is not cost effective. Even if a program is not cost effective, however, safety considerations may be important to consider. Findings indicated that each type of train simulators might be used with each type of training programs appropriately for improving cost-effectiveness of a train simulator.

Purpose: This study developed and evaluated a systematic intervention among medical ICU nurses for preventing ventilator-associated pneumonia (hereafter VAP). Methods: A VAP prevention program was proposed based on a literature review, revised to fit the target situation, and validated. It was composed of one-time interventions including education, pamphlets, hand cultures, and a quiz event, as well as repeated interventions such as posters, reminders, posting hand culture results, and performance feedback. A simulated control group pretest-posttest design was used to verify the effectiveness of the VAP control program. The incidence of VAP among ICU patients was measured both during 3 months before (n=80) and during 3 months after (n=75) intervention. Results: The VAP prevention program's effectiveness, with a pre-intervention VAP rate of 17.38 and post-intervention rate of 11.04 per 1,000 ventilator days, showed a clinical tendency to decrease, but the difference was not statistically significant (p=.750). Conclusion: A VAP prevention program of multiple interventions can be useful in decreasing the VAP rate. Given that the monthly decrease in the VAP rate was not considered statistically significant, long-term research needs to be done. Additionally, since this study targeted only nurses, it is suggested that future research targets other health care workers who can influence VAP rates.

The research questions drawn to attain the purpose of the research are as follows. Initially, analyze the contents related to the plant appearing in the textbooks of wise life, science and practical arts of the 7th elementary school curriculum. Secondly, develop a plant utilizing environmental play program targeted towards the 4th grade elementary school students with the results of the textbook analysis as the foundation. Third, apply the plant utilizing environmental play program into the classroom to verify its effectiveness. Based on the conclusion of this research, the following is to be proposed. First, the revitalization of regional environmental education utilizing the various surroundings of the region is essential. Also, the current method of education, which is focused on theoretical knowledge, and being operated in most of the schools need to be changed over to diverse environmental education programs that are linked with the region. For this, an internet based database, information sharing and exchange program centralized around the regional environmental education center needs to be prepared. Moreover, since this research had developed an environmental play program utilizing plants that focused on the 4th grade elementary school students to verify its effectiveness, the development for environmental play programs dealing with various themes for each grades is required. Lastly, although this research has verified the effectiveness in the variables of ecological knowledge, environmental susceptibility, environmental attitude, environmental concern, environmental function and responsible environmental behavior amongst the variables of environmental literacy but there requires a succeeding research considering the variables that haven't been included in this research.
