  • We proposed a video summarization algorithm based on an ERP (Event Related Potentials)-based topic relevance model, a MMR (Maximal Marginal Relevance), and discriminant analysis to generate a semantically meaningful video skim. We then conducted implicit and explicit evaluations to evaluate our proposed ERP/MMR-based method. The results showed that in the implicit and explicit evaluations, the average scores of the ERP / MMR methods were statistically higher than the average score of the SBD (Shot Boundary Detection) method used as a competitive baseline, respectively. However, there was no statistically significant difference between the average score of ERP/MMR (${\lambda}=0.6$) method and that of ERP/MMR (${\lambda}=1.0$) method in both assessments.

  • The purpose of this study is to find out the level relevance of the kindergarten curriculum in terms of the kindergarten and elementary school curriculum articulation. For this purpose, a model was developed to assess the level relevance of the curriculum. Next, the achievement standards of the curriculum were analyzed by using this model. Finally, teachers' guidebooks were analyzed, too. The following results were obtained from the analysis. First, five of the 14 achievement standards are rated as 'relevant', and nine of them were 'irrelevant'. Also, six of the irrelevant achievement standards were rated as 'overlap', two of them were rated as 'retrogression', and one of them was rated as 'gap'. I found a lot of problems with the level relevance in the kindergarten curriculum. As the results to analyze teachers' guidebooks, I found that there were the great frequency difference in the activities of teachers' guidebooks.

  • Purpose - The purpose of this study is to examine the information effect of securities firm's net operating capital, securities firm's regulatory purposes capital, by analyzing the value relevance of net operating capital. Design/methodology/approach - This study was empirically analyzed using samples of domestic listed securities firms in the past 12 years, and multiple regression analysis and Vuong (1989) test were used together as specific research methods. Findings - First, it was found that the net operating capital of securities firms has an incremental value relevance that is added to basic accounting information (equity book value, profit or loss information). Second, after classifying equity capital on the books into net operating capital and the rest of equity capital, the value relevance of net operating capital was significantly higher than that of other equity capital. Research implications or Originality - The results of this study indicate that the level of regulatory capital in the securities industry can be used in the process of evaluating firm value in the capital market, and it is significant in that capital market evaluation can be stratified according to regulatory purposes.

  • The purposes of this study are to analyze relevance judgement of college students' problem solving process and suggest improvements for information literacy education in higher education. The in-depth interviews were conducted with 9 subjects to identify relevance judgement processes and problems. As a result, the main problems during relevance judgement processes were judgement about content of document aligned with subject's opinion, judgement about reliability of newspaper articles, shortage of relevance judgement time due to deadline of an assignment and judgement of relationship of documents and evaluation result. The recommendations for information literacy education are as follows: objective relevance judgement education, guidance of reliable information source;showing guideline of using reference information by professor and emphasis of engaging in information (4.1 stage of Big 6).

  • This paper addresses a methodology for monitoring the first phase('92-94') progress and its implication fo Highly Advanced National R&D Projects (HAN or G7 project) in Korea. The authors suggest a three-stage life cycle model for the management of national R&D program; planning stage, implementing & monitoring stage, and evaluating & harvesting stage. The interim evaluation, the main focuses of this paper, is one of the key issues for the effective management of national R&D program at the implementing & monitoring stage. The conceptual framework of the interim evaluation was developed both through reviewing related literature and considering the characteristics of the HAN program. A stepwise procedure of interim evaluation was introduced: 'initial screen' and 'detailed examination'. At initial screen all 11 projects were reviewed in terms of both their relevance and performance in order to decide whether further detailed scrutiny is needed or not. If there exist critical problems on the relevance or on the intermediate progress of each project, it is to be under further detailed examination. Evaluation was initiated by the G7 Planning and Evaluation Committee, which was established for advising, directing, and monitoring the HAN Projects, with the help of large number of experts from industries, universities, and research institutes. The monitoring results were reported to the related ministries and project coordinating agencies, and reflected in the second phase.

  • Recently, consumer researchers have suggested that consumers evaluate brand by subjective memory-based-emotion which was formed by their experience. However, relatively little consumer research has been done to explore conditions under which memory-based-emotion is used in brand evaluation. Therefore, this study explored the conditions to facilitate usage of memory-based- emotion such as accessibility, representativeness, relevance of consumption goal, when consumers evaluate brand. In addition, we investigated the factors that influence responses of memory-based- emotion, such as similarity of encoding and retrieving condition and level of organization. The results of this study suggest that level of organization was positively related to accessibility and representativeness. But similarity of encoding and retrieving condition was not related to them. And accessibility, representativeness influence on use of memory-based-emotion in consumer brand evaluation. But relevance of consumption goal did not influence on use of memory-based-emotion in consumer brand evaluation.

  • In the Information Retrieval System. the relevance of retrieved items is determined by the judgement of the user and thus the evaluation of the system efficiency counts on the cognizance of users to some extent. The relevance feedback mechanism provides a device allowing iterative searches during which the query can be modified and refined based on user input from the relevant documents. The feedback system are generally reported to outperform non-feedback systems. The procedures and algorithms to implement the feedback mechanism are surveyed in this paper.

  • The purpose of this study is to investigate the current state of the contents of the mathematics education that are implemented for 3-10 grade students in Korea. To satisfy the purpose of the study, we conducted a nationwide questionnaire to get opinions from students on the relevance of the mathematics curriculum. 4,158 elementary school students, 4,571 middle school students, and 1,653 high school students participated in this survey. Many students feel that the quantity is relevant, so the requirement of reduction in quantity is a little. Also secondary students feel that mathematics is difficult and this condition becomes more serious in proportion as grade. Finally we noticed the difference between sexes, grades, and tracks of studying in every question.
