In this study, the career barriers exploration counseling program was carried out to research the factor on the career barriers of women's college students. And then the effect of the career barriers exploration counseling program on career preparation behavior of the women's students was analyzed. The program that referred to the career counseling program proposed in domestic and career material suggested in Korean Women's Development Institute and Korea Research Institute for Vocational Education & Training was adopted in this investigation. Moreover referred to the previous research and reference related to career counseling that had conducted the related factor on career barriers and career preparation behavior. First of all, the program was reconstructed by referring to the Gottfredson(1981)'s career development theory. In order to verify the effect of the program on career preparation behavior of women's college students, two times tests were carried out on 10 persons of the experimental group and the control group respectively, before and after the program was performed. And then the ANCOVA was done on the difference between the post-test results of the experimental group and the control group. Findings of this study might be summarized as follows: First, the post-test result in the experimental group on career barriers was significantly lower than in the control group. Second, on career preparation behavior the result in the experimental group was higher than in the control group. Therefore, the career barriers exploration counseling program had a significant influence on career barriers of women's college students and the program impacted on career preparation behavior of women's college students significantly.

Natural disaster has been hard to prevent the occurrence of itself, thus in order to reduce the economic damages and loss casualties, it is important to be prepared in cases that the disasters should occur in advance. Interest of the related project to prevent various natural disasters has been grown along with an investment in Korea. Along with this movement, when investments related to natural disaster prevention projects were built on, the post evaluation that can verify the ripple effects of those investments on the community should be emerging as an essential task. For evaluating the effects of public investment projects such as natural disaster prevention projects in this study, the related researches would continue through qualitative analyses, for example, cost-benefit analysis. Even the qualitative analysis alone cannot fully explain the effects of those projects, the diverse methods of analyzing and evaluating those effects might not have been presented in those fields. For the post evaluation of natural disaster prevention projects through the qualitative analysis, this study derived subjects that had effects on the post evaluation of natural disaster prevention projects. Also, employing the structural equation modeling (SEM), the causation between post evaluation subjects and the effects of projects were quantitatively analyzed, and the weighting factors of evaluation items were calculated respectively. Based on these results, post evaluation index formula was proposed for the natural disaster prevention projects in Korea.

This study was to analyze the learning effectiveness of multi-media based class by comparing with traditional classroom method. The "Distribution Working Subject" course that is one of the required courses of Vocational high school was selected and its contents were digitalized on MS Powerpoint for multi-media based class. The thirty students were sampled for each experimental and control groups. The homogeneity and learning achievement of sample groups were tested for experiment. Same teacher took the classes of two groups and delivered same contents of course. Only difference between two groups was the delivery method, one is traditional classroom teaching method and the other was the multi-media based class. The learning achievements and satisfaction of sample were post-tested in order to analyze the learning effectiveness by comparing two teaching methods. The results showed that there was a significant difference between experimental and control group in learning achievement after ANCOVA controlled pre-test as covariance(F=5.08, p<.05). It means that the learning achievement of multi-media based class was higher than that of traditional classroom group. The results also showed that a significant difference in students' satisfaction between two groups (t=5.57, p<.001). This study concluded that using multi-media in class could produce more learning achievements and satisfaction of students than traditional classroom method.

Conducting statistical analysis of foundation resistance using sufficient number of well-performed load test results is prerequisite for the calibration of reliable resistance factors for foundation LRFD. In this study, a rational analysis method is proposed so that the proof pile load test results can be reflected in update of resistance statistical characteristics based on Bayesian theory. Then, resistance factors for driven steel pipe piles compatible with Korea foundation practices are updated by implementing this rational analysis method. To accomplish the resistance factor updates, (1) prior pile resistance distribution is constructed based on the results of pile load tests, which loads are imposed at least up to their ultimate limit loads. (2) likelihood function is obtained from the results of proof pile load tests, and (3) posterior pile resistance distribution is updated by combining these prior pile resistance distribution and likelihood function. The resistance factors are updated using the posterior pile resistance following the first-order reliability method (FORM). From the possible results of five consecutive proof pile load tests, the updated resistance factors vary within ranges of 0.27-0.96 and 0.19-0.68 for target reliability indices of 2.33 and 3.0, respectively. Consequently, it was found that the Bayesian theory-implemented method enables the updates of resistance factors in an efficient way when reliable resistance factors are not available due to the lack of well-performed pile load test results.

합성전장훈련체계를 통해 지휘관 및 참모 훈련뿐만 아니라 기존의 야외 실기동훈련시 제한 되었던 전투경험을 가능하게 함으로써 전장 적응능력을 향상시킬 수 있으며, 훈련자체가 전투임을 인식하고 전장실상 및 전투양상에 지휘관 및 각개병사의 사고가 지향되도록 할 수 있을것이다. 훈련후에는 추상적이고 주관적인 훈련성과 검증이 아닌 과학적 분석과 정밀한 사후검토 체계에 의한 교훈도출과 특정국면을 재현한 전술토의가 가능하므로 보다 수준 높은 전술적 식견과 전투감각을 향상시킬 수 있을 것으로 기대된다.
