This paper attempts to show that consumers' own information processing mode can play an important role in inducing favorable product evaluations, which is the most key goal of marketing. Th elaboration likelihood model contends that consumers' motivation and knowledge, in addition to the outside marketing information, affects the evaluation process. On the other hand, The resource matching hypothesis suggests that an excessively high level of information processing may lead to negative evaluations. In this study, Need for closure exacerbated overall evaluations of consumers. Such relationship was more salient in the condition of low severity that in the condition of high severity. Also under the situation of low severity, consumers with high level of relevant knowledge made evaluations more favorable, compared to the consumers of low knowledge. On contrast under the situation of high severity, relevant knowledge leaded to less favorable evaluations. This experiment identifies the appropriateness of the elaboration likelihood model and the resource matching hypothesis. Especially This study suggests an rare example that consumers' knowledge may not paly an desirable role in making their judgments.

이 연구의 목적은 과학적인 문제를 해결하기 위하여 가설을 형성하는 상황에서 최초로 상정된 가설들이 어떤 정교화 과정을 거쳐 더욱 발전하게 되는지 탐색하는 것이었다. 이를 위하여 예비 초등 교사들이 조를 이루어 지구과학의 귀추적 탐구 과제를 해결하는 상황에서 자료를 수집하여 분석하였다. 그 결과, 예비 교사들의 가설 정교화 과정을 크게 '이론에 의해 유도되는 과정'과 '증거에 의해 유도되는 과정'으로 나누어 볼 수 있었다. 이론유도과정은 다시 '내적 정합성'과 '외적 정합성'을 추구하는 경우로 구분되었으며, 증거유도과정은 '직접 증거'에 의한 것과 '간접 증거' 또는 '유사 증거'에 의한 것으로 구분되었다. 또, 각각의 경우에 잘못된 이론이나 그릇된 증거에 의해 가설이 수정되어지는 사례도 발견되었다. 이러한 연구 결과가 과학 교육과 관련 연구에 시사하는 바를 논의하였다.

The purpose of this paper is to investigate the effects of anti-smoking advertising on attitude toward anti-smoking and behavioral intention to quit smoking in terms of audience's involvement with anti-smoking and knowledge on smoking. For this, a total of 10 hypothesis were established and statistically tested. According to the results, all but hypothesis 1-1(attitude toward anti-smoking is more favorable in the high involvement condition than in the low involvement condition) were unfortunately rejected. These results can be justified by theoretical explanations such as Hierarchy Effects Model or Elaboration Likelihood Model. In addition, some methodological reasons were provided as well.

Many previous research studies on extractive text summarization consider a subset of words in a document as keywords and use a sentence ranking function that ranks sentences based on their similarities with the list of extracted keywords. But the use of key concepts in automatic text summarization task has received less attention in literature on summarization. The proposed work uses key concepts identified from a document for creating a summary of the document. We view single-word or multi-word keyphrases of a document as the important concepts that a document elaborates on. Our work is based on the hypothesis that an extract is an elaboration of the important concepts to some permissible extent and it is controlled by the given summary length restriction. In other words, our method of text summarization chooses a subset of sentences from a document that maximizes the important concepts in the final summary. To allow diverse information in the summary, for each important concept, we select one sentence that is the best possible elaboration of the concept. Accordingly, the most important concept will contribute first to the summary, then to the second best concept, and so on. To prove the effectiveness of our proposed summarization method, we have compared it to some state-of-the art summarization systems and the results show that the proposed method outperforms the existing systems to which it is compared.

The purpose of this study is to find out the effect of hypothesis formulations using abduction on science processing skills and the creative thinking activities. As the subject, 2 classes in the $6^{th}$ grade of B elementary school located in Busan were selected. Through the pre/post inspection design between experiment and comparison class, the units of science courses in the second semester of $6^{th}$ grade '1. A change in the weather' and '2. Various gases' were applied. The results were as follows: Firstly, the test on science processing skills showed that there was not statistic meaningful differences between the two groups. And, in the sub-parts, there was not statistic meaningful differences between the two groups. Secondly, it was observed that it would have a meaningful effect to improve the creative thinking activities of students who performed hypothesis formulation using abduction. Especially, through this, the experimental class gave a positive effect on the 'Fluency' and 'Elaboration', one of lower categories of the creative activities. The results of 'Flexibility' and 'Originality' in the experimental class were higher than those of students in the comparative class. However, according to statistical analysis, this result is meaningless. Thirdly, on the survey about the hypothesis formulation using abduction, many students thought that this learning method was very interesting and helpful to study science. In addition, it was observed that the ability to use abduct thinking was improved more than ever before.

The purpose of this study was to verify the effects of science classes using abductive strategies on the scientific concept understanding and meta-cognition. The subjects included two classes of sixth graders from K Elementary School in B Metropolitan City and they divided into two groups. Research group was composed of 21 students(10 boys, 11 girls) and comparative group was composed of 21 students(11 boys, 10 girls). In order to achieve aims of this study, proper contents to apply abductive strategies were selected from the first semester science curriculum for sixth graders. Also five-steps study papers were designed to elicit abductive reasoning. While the research group received 20 times of reframed science lessons using abductive strategies, the comparative group received common science lessons according to the teachers' manual. The results of this study are as follows. First, science classes using abductive strategies were effective for the scientific concept understanding. Also there were statistically significant differences between the research group and the comparative group in overall science sub-domain. In the process of hypothesis formulating, students tried to find out scientific causes thoroughly to present the optimal explanation and they concentrated on the analysis of each scientific concept. It is thought that this process contributed to better understanding in scientific concepts. Second, science classes using abductive strategies were effective for improving meta-cognition. There were statistically significant differences between the two groups and especially in monitoring that is one of sub-factors of meta-cognition. It indicates that hypothesis formulating process gave positive effect on meta-cognition by stimulating critical thinking and manifesting elaboration.

The purpose of this study was to examine the relationship between life stress and depression, and the effect of social support in postpartal $4{\sim}6$ week women. Theoretically social support is thought to mediate the relationship between life stress and depression. Data were collected from June 1 to July 30, 1999. The data were analysed by use of SPSS. Two hypotheses were tested using Gamma, a measure of association for ordinal variables. Partial gamma was used to test the third hypothesis. Patterns of elaboration described by Babbie(1986) were selected to interpret the relationship of the three variables in the analyses. The results of this study are summarized as follows ; There was a positive relationship between life stress and depression (Gamma=.45, P=.017), and an inverse relationship between social support and depression (Gamma=-.49, P=.009). Thus the first, two hypotheses were supported. 2. When social support was controlled, the relationship between life stress and depression increased under the condition of low social support, but with high social support, the relationship decreased. It can be interpreted that life stresses are positively related to depression under the condition of low social support, however this relationship cannot be expected with high social support.
