기존 터널에 근접하여 절리암반 굴착시 사면의 적절한 보강방법 및 시기는 굴착사면과 터널과의 근접도, 굴착사면 경사는 물론 절리상황에 의해 영향을 받자만 현재까지는 경험적으로 결정되고 있다. 본 연구에서는 터널에 근접하여 절리암반 지반을 굴착시 굴착단계에 따른 굴착사변에서의 하중전이 특성과 터널거동과의 상관관계를 분석하기 위하여 절리각도와 굴착사면 경사를 영향인자로 한 대형 모형시험을 실시하였다. 시험결과, 터널변형은 터널 천정부 또는 바닥부에 근접한 절리면 굴착시 가장 크게 발생을 하였으며, 사면과 터널의 안정성은 굴착사면의 경사와 관련하여 굴착단계에 따라 변화하였다. 향후 본 연구결과를 활용하여 절리암반에서의 터널과 사면의 보강방안을 도출하고자 한다.

In order to analyze travel mode choice behavior, behavioral models including logit model, based on revealed preference theory, have been using easily measurable variables such as individual socioeconomic characteristics and physical attributes of travel modes. But some recent attitudinal models of travel choice behavior have implied that the negligence of individual psychological variables and individual choice constraints in travel mode choice might preclude better prediction of individual travel mode choice behavior. In this context, this study was attempted to reconstruct an attitudinal model(AM), especially focused on the decision rules in travel mode choice decision making process, consistent with the conceptual framework relating individual attitude and choice constraints to choice behavior. And to evaluate the strengths of the AM to other comparative models(logit, linear-additive, conjunctive, lexicographic model) in predicting travel mode choice bebavior, an empirical study of the mode choice in work-trip to CBD in Seoul was performed. According to the results the percent of correct prediction(PCP) derived from the AM was higher than those derived from comparative models by at least 7 to 20% in predicting travel mode choice. But each model produced a different prediction accuracy depending on market segmentation by travel modal users, individual socioeconomic characteristics, transportation system characteristics, and satisfaction levels. The finding that different groups divided by a certain criterion employ different decision rules supports the necessity of developing a choice model such as the AM combining compensatory and noncompensatory decision rules, and suggests that a proposed transportation system management plan or policy may have different effects on each group.

The purpose of this study was to test the fitness and explainable power of TPB-SE model to the behavior of breast self examination and it was to examine effectiveness of education for Intention and behavior of breast self examination. The subjects were 122 womens under baby sitting teachers' training programs at "S"college on Po Hang city, Kyung Pook province from May 10, 1998 through October 17, 1998. Among 122 subjects, 61 were placed in experimental group and 61 in control group. The experimental group was treated by researcher who administered booklet, slide and breast model. Collected data were analyzed through $X^2$-test, t-test, MANOVA, ANCOVA, Pearson correlation coefficient via SPSS/PC and applied LISREL 8.0 programs to test TPB-SE model. The result of this study was summarized as follows: 1. TPB-SE model with additions of self efficacy from TPB fits well for predictive factors of behavior of breast self examination and it also fits well for data (GFI=.91, $R^2$=.45). 2. Behavior score of breast self examination in the experimental group with already educated with breast self examination was significantly higher than that of control group (Wilks's value=.711, p=000). Through the results of this study, TPB-SE model with additions of self efficacy from TPB fits well for predictive factors of behavior of breast self examination and the education of breast self examination was effective to improving intention and behavior of breast self examination. I herewith reached final conclusions that the behavior of breast self examination should be regarded as one of health behavior for all women and the health education to women for breast self examination will be important job role for all nurses. In addition to above, the intervention through effective education designed for improving attitude, subjective norm, perceived control, self efficacy and intentions will be necessary step for any improvement of women' health behavior.

This paper explores antecedents of entrepreneurial and job search intentions based on the theory of planned behavior. Additionally, it examines the impact of entrepreneurship and job search education on these antecedents of entrepreneurial and job search intentions. The research model has been validated by analyzing 1,432 responses from undergraduate students in South Korea. The results of analysis provide several findings: First, entrepreneurship attitude, entrepreneurship subjective norm, and entrepreneurship self efficacy showed significant positive effects on entrepreneurial intention, but their effects on job search intention were insignificant. Second, while job search attitude showed significant positive effects on both intentions, job search subjective norm showed a significant effect only on job search intention, and job search self efficacy showed a significant effect only on entrepreneurial intention. Third, entrepreneurship education increased all the antecedents of entrepreneurial intention, and reduced job search attitude. These results imply that entrepreneurship and job search education should be managed comprehensively, considering their cross-effects on the antecedents of entrepreneurial and job search intentions.
