The aim of this study is to examine the effect of self-efficacy of married immigrant women on the quality of life and the moderating effect of family support in the effect relation. For this purpose, the study carried out a questionnaire survey to married immigrant women who attended multi-cultural family support centers in order to take language education and job education. Total 279 were selected as valid samples. The specific analysis results of this study are as follows. Firstly, the self-efficacy of married immigrant women has positive (+) effect on the quality of life. Secondly, the informational support in the family support has negative (-) effect on the quality of life, but evaluative and material support have positive (+) effect. In the interaction with self-efficacy, the emotional support has negative (-) effect, but the interaction with evaluative and material support has positive (+) effect. But, the interaction with informational support has no significant effect on the quality of life. The key factor affecting the quality of life on married immigrant women is the Korean family. Therefore, their quality of life can be enhanced as well as stable settlement in Korea if the families of husbands accept married immigrant women as their family members and support them.

Data mining is the process of analyzing a huge database from different perspectives and summarizing it into useful information. One of the well-studied problems in data mining is association rule generation. Association rule mining finds the relationship among several items in massive volume database using the interestingness measures such as support, confidence, lift, etc. Typical applications for this technique include retail market basket analysis, item recommendation systems, cross-selling, customer relationship management, etc. But these interestingness measures cannot be used to establish a causality relationship between antecedent and consequent item sets. This paper propose causal association thresholds to compensate for this problem, and then check the three conditions of interestingness measures. The comparative studies with basic and causal association thresholds are shown by numerical example. The results show that causal association thresholds are better than basic association thresholds.

최근 자동차기술의 발달로 인한 차량의 경량화, 고급화 추세는 더욱 개선된 승차감을 요구하고 있다. 승차감에 영향을 미치는 주요인으로서는 엔진의 진동과 소음, 변속장치, 구동축 등의 구동 계통의 진동 및 소음, 그리고 노면으로부터의 진동, 외부 공기의 흐름에 의한 소음 등 여러가지가 있다. 엔진지지계는 이중 엔진의 진동 및 소음을 절연하는 기능을 맡고 있고 동시에 엔진하중의 지지, 변위제한, 충격흡수 등의 기능도 가지고 있다. 실제에 있어서 엔진지지계는 진동 및 소음 절연의 기능 외에 다른 기능도 갖고 있으나 이중 가장 어렵고 해석이 곤란한 것은 결국 진동절 연성능이라고 할 수 있다. 그러나 여러 가지 제약조건이 있으므로 최적의 진동절연특성의 실 현이 항상 가능한 것은 아니고 방진고무의 특성치난 지지각도 등의 어느 범위안에서만 선택이 가능하므로 실제 설계에 있어서는 적용상의 특정조건을 만족시키는 초기설계치를 정하여 그때의 진동절연특성을 평가하고 기준이하일때는 설계치를 재조정하여 다시 평가하는 접근방식이 실질 적이다. 따라서 이 설계과정에 필요한 엔진지지계의 진동절연특성해석 및 평가용 컴퓨터 프로 그램을 개발하였으며 그 해석치와 실험결과를 비교하여 타당성을 입증하였다.

Jacked pile that involves the use of hydraulic jacks to press the piles into the ground is free from noise and vibration, and is possibly installed within a limited construction area. Thus, as an alternative to conventional pile driving methods, pile jacking could become widely accepted for the construction projects in urban area (e.g., reconstruction or remodeling construction projects). Great concern has arisen over the prediction of axially loaded jacked pile behavior. Against this background, a series of pile load tests were hence conducted on a jacked steel pipe pile installed in weathered zone (i.e., weathered soil and weathered rock). From the test results, base resistance and shaft resistance for each test condition were evaluated and compared with the values predicted by the previous driven pile resistance assessment method. Test results showed that the previous driven pile resistance assessment method highly underestimated both the base and shaft resistances of a jacked pile; differences were more obviously observed with the shaft resistance. The reason for this discrepancy is that a driven pile normally experiences a larger number of loading/unloading cycles during installation, and therefore shows significantly degraded stiffness of surrounding soil. Based on the results of the pile load tests, particular attention was given to the modification of the previous driven pile resistance assessment method for investigating the axially loaded jacked pile behavior.

The purpose of this study is to provide necessary information to understand characteristics of vocational high school students and to enhance academic engagement through social support of teachers, leading to help research of teaching and learning strategy. A survey was conducted on 990 engineering major students attending 11 vocational high schools in Seoul metropolitan, Chungcheong, Jeolla, Kyeongsang and Kangwon regions. A questionnaire consists of measurement tools for the academic engagement (21 questions) and the social support of teachers (25 questions). The findings of this study are as follows: First, it is found that the level of students' academic engagement was high. But it appears that the students showed low engagement of emotion compared with that of behavior and cognition. There was no level difference according to gender, but there was a considerable difference according to a school year. The first year students' level of engagement was higher than the second and the third year students' in terms of cognition and emotion. Second, it shows that the level of the teachers' social support was normal, which was in the order of appraisal support, instrumental support, informational support, and emotional support. Especially, the level of appraisal support and instrumental support was most. Third, there were correlation and explanation between students' academic engagement and teachers' social support. Moreover, the result that teachers' emotional support has high correlation and explanation in qualitative terms of academic engagement support the importance. Therefore, it is concluded that the social support of teachers can make an positive influence on improving the academic engagement of students and provide students with adaptability and satisfaction with their school life, which may give students a positive effect in emotional development, self-formation, and complement.
