Strategic decision on the execution of national security improvement project is greatly important for the present and future national security. Though, the importance of strategic decision, decision making process has been executed under one-way thinking framework. This research provides a decision-making tool with make-or-buy approach for the national security improvement policy execution methods: foreign purchase and military R&D project, and, via simulation, confirms dynamic change of military capability index respect to change in ratio of foreign purchase and military R&D. A result shows that current ratio of foreign purchases and military R&D is insufficient for national security improvement policy goal. Applying the model from this research provides an appropriate ratio for short term and long term defense strategy and policy goal, and consequent result of increase in national security capability. Thus, this research model can be effectively utilized for national security improvement project.

This study aimed to analyze the effect of total allowable catches (TACs) on the target species. First to effects analyse of TACs, the 8 TAC target species and 75 non-target species were selected for which catch data were available before and after the introduction of the TACs. The 8 target species were simply compared to catch changes before and after TACs. Through the comparison, it was confirmed how the catches of target fishes have changed after the implementation of the TACs. Secondly, the Difference In Differences(DID) analysis was conducted to confirm the effects of the TACs on the catches of the target fishes using the catch data of 8 TAC target species and 75 non-TAC species. Finally, to overcome the limitations of the DID analysis, the random effects model was estimated to confirm the effects of the TACs on the catch of the TAC target species. Overall, this study confirmed that the TACs affects catches of target species, not only through simple comparisons of catches before and after the introduction of the TACs but also through econometric analysis.

Background. Breast cancer is the most common form of cancer among Korean women. Only 14 % of urban women and 10% of rural women in Korea, however, participated in breast cancer screening behavior in 1998 (Korean Ministry of Health & Welfare, 1999). Purpose. The aim of this study was to evaluate the effect of community-based breast self-examination (BSE) education programs in Korea. Methods. First, breast cancer risk appraisals were done with 1,977 rural women. Of the 1,977 women, nearly 30% (n=494) had a higher or equal to borderline risk of developing breast cancer. This quasi-experimental study was conducted to target these women with a high or equal to borderline risk of breast cancer. The risk appraisal feedback and breast self-examination education were used as an intervention for breast cancer prevention and early detection. Results. After a 3-month follow-up, 30.5% of the women in the intervention group performed regular BSE compared to 10.2 % of women in the control group. The mean knowledge score related to breast cancer and BSE was significantly higher for the women in the intervention group than that in the control group.

Noise externalities are a ubiquitous problem in modern societies. Research to estimate damages and potential efficient solutions therefore is important for addressing such problems. The results of a hedonic property model show that noise has a statistically significant and quantitatively important negative effect on property values. The key results for the best model show that damages (in year 2000 dollars) are - $5000 ${\ast}$ (ln dB), where dB is noise measured in decibels, allowing for the influence of other factors. Because ln(dB) is a strictly concave funaion, the "noise damage function"exhibits diminishing marginal effects with noise.

Recently, enterprises have reinforced security control in order to prevent infringement of personal information and abuse of customer information by insiders. However, the reinforcement of security control by enterprises makes it difficult for internal users to perform business by using a business information system. There is, therefore, a need for research on various fields, which makes it possible to establish an appropriate security control policy while minimizing an impact on business. The present research verifies and analyzes an impact on difficulty in business of internal users using customer information, which is caused by security control performed by display restriction on customer information identifiers. The present research is intended to academically develop a technique for statistically analyzing an impact degree and a causal relationship between security control and an impact on business, which is a dichotomous variable, and to practically contribute to the establishment of an efficient security policy in consideration of an impact on business when an enterprise applies security control. A research target was internal business information systems of domestic securities enterprises, data was collected by questionnaire, and verification/analysis was performed by logistic regression analysis.

The purpose of this study is to review the current state of energy education in Korea and identifies barriers faced by teachers in doing energy education. For this purpose, this study carried out a questionnaire survey targeting energy saving policy research-schools. The results of this research are as follows. First, teachers facing barriers in energy education pointed out the lack of teaching text and students' interest in energy, and work stress as main barriers. Second, teachers facing barriers in energy education rather than teachers not facing barriers are inclined to do more education at Ordinance hour and Jongrye hours. It implies that more energy education textbooks for Ordinance hour and Jongrye hours need to be developed. Third, teachers facing barriers in energy education desire more chances for training program, compared with teachers who do not feel barriers. It implies that opportunities for teacher training program need to be expanded.
