Data mining is the representative analysis methodology in the era of big data, and is the process to analyze a massive volume database and summarize it into meaningful information. Association rule technique finds the relationship among several items in huge database using the interestingness measures such as support, confidence, lift, etc. But these interestingness measures cannot be used to establish a causality relationship between antecedent and consequent item sets. Moreover, we can not know association direction by them. This paper propose causally confirmed association thresholds to compensate for these problems, and then check the three conditions of interestingness measures. The comparative studies with basic association thresholds, causal association thresholds, and causally confirmed association thresholds are shown by simulation studies. The results show that causally confirmed association thresholds are better than basic and causal association thresholds.

Association rule of the well-studied techniques in data mining is the exploratory data analysis for understanding the relevance among the items in a huge database. This method has been used to find the relationship between each set of items based on the interestingness measures such as support, confidence, lift, similarity measures, etc. By typical association rule technique, we generate association rule that satisfy minimum support and confidence values. Support and confidence are the most frequently used, but they have the drawback that they can not determine the direction of the association because they have always positive values. In this paper, we compared support, basic confidence, and three kinds of confidence measures useful for classification model building to overcome this problem. The result confirmed that the causal confirmed confidence was the best confidence in view of the association mining because it showed more precisely the direction of association.

The purpose of this study was to develop picture testing instrument for measuring children's causal reasoning ability on events that can occur in daily life. The measurement instrument contains three domain of human development; haman behavior domain, human psychology domain, and natural/physical domain. Through this study, researchers designed a concept model based on theoretical framework and prior studies and investigated the reliability and validity of the measurement instrument which was developed in accordance with the concept model. For the empirical validation research, a pretest was conducted to 336 elementary school students in grade 2 to 4 in Seoul. Considering reliability and validity of the developed measurement instrument and factor loadings, researchers sorted out 18 questions. And then 18 question test and KICE Critical Thinking Ability Test was conducted to 509 elementary school students in grade 1 to 4 in Seoul. According to the result of the tests, the researchers sorted out final 12 questions. The Cronbach's alpha, reliability of the children's causal reasoning ability test consisted of the final 12 question, was significant as .72. Also, the result of exploratory factor analysis showed that factors of this test were haman behavior domain, human psychology domain, and natural/physical domain. Moreover, the correlation between the KEDI Reasoning Ability Test(2003) scores and the scores of the test developed in the current study was significant as .55. Finally, the result of the analysis about children's grade differences, the development by discrepancy of age was significant in total points and that of each domain. The children's causal reasoning ability test developed by this study can be useful not only for the evaluation of children's thinking ability but also for screening of the handicapped children in thinking ability development.

본 연구는 대학의 창업교육 서비스 품질이 교육만족과 창업역량, 창업의지에 미치는 영향에 관한 연구이다. 대학에서 다양한 창업교육이 진행되고 있지만 창업성과에 대한 연구는 많이 이루어지지 않고 있다. 본 연구에서는 창업성과를 높이기 위한 요인을 분석하기 위해 창업교육의 서비스 품질이 교육만족과 창업역량, 창업의지에 미치는 영향에 대해 살펴보았다. 첫째, 창업교육 서비스 품질을 측정하기 위해 서비스 품질에 대한 이론적 배경을 바탕으로 유형성, 신뢰성, 반응성, 확신성, 공감성 등 5개 요소 21개의 문항을 설정하고, 설문 분석 결과를 바탕으로 창업교육 서비스 품질이 교육만족과 창업역량에 미치는 영향을 알아보았다. 둘째, 고객 만족에 대한 선행연구를 바탕으로 창업교육 수강생의 교육만족을 정의하고, 창업역량의 요소 중 성취역량, 창의성역량, 개념화역량, 사회적 역량 등에 미치는 인과관계를 분석하였다. 셋째, 교육만족과 창업역량이 창업의지에 미치는 인과관계를 분석하였다. 그 결과, 창업교육 서비스 품질은 기존의 연구와 다르게 유형성과 신뢰성이 하나의 요인으로 분석되어 반응성, 확신성, 공감성 등 4개 요인으로 확인되었고, 4개의 요인으로 구성된 창업교육 서비스 품질이 교육만족과 창업역량에 영향을 주는 것으로 확인되었다. 또한, 창업역량 요인을 4개로 정의하여 설문을 분석한 결과 성취역량과 창의성역량이 하나의 요인으로 분석되어 개념화역량, 사회적 역량과 함께 3가지 요인으로 확인되었다. 이는 교육만족에 영향을 받는다는 것을 확인할 수 있었다. 창업의지는 창업역량에 영향을 받았지만, 교육만족에 직접적인 영향을 받지 않는 것으로 확인되었다. 이러한 결과는 교육만족이 창업역량을 통하여 창업의지에 간접적인 영향을 미친다는 것을 의미한다. 차후 연구에서는 대상을 여러 지역 혹은 전국으로 확대할 필요성이 있으며, 다른 변수와의 접근 방법을 가지고 연구되어야 할 것이다.
