Web usage mining is a research field for searching potentially useful and valuable information from web log file. Web log file is a simple list of pages that users refer. Therefore, it is not easy to analyze user's current interest field from web log file. This paper presents web usage mining method for finding users' current interest based on fuzzy categories. We consider not only how many times a user visits pages but also when he visits. We describe a user's current interest with a fuzzy interest degree to categories. Based on fuzzy categories and fuzzy interest degrees, we also propose a method to cluster users according to their interests for user modeling. For user clustering, we define a category vector space. Experiments show that our method properly reflects the time factor of users' web visiting as well as the users' visit number.

This is the research on the correlation between the marketing activities conducted by the companies participating in the overseas exhibitions in the exhibition and the satisfaction of the visitors. I have been able to obtain the following findings through the positive research on the satisfaction of the visitors to the overseas exhibitions. The research findings show that the external elements of the participating companies such as 'external appearances of booths, interior facilities and the atmosphere', 'designs of exhibits', 'size of the participating companies', and the publicity elements of the participating companies such as 'the degree of application of mass media', 'prior publicity of the participating companies', etc. among the marketing activities conducted by the participating companies in the exhibition affect the interest and repeat business deals of the visitors. The findings also show that the elements to induce the interest of the visitors such as the booth design and display of products where the participating companies may produce their unique image and the prior publicity to the visitors constitute the important elements of marketing. It has also been revealed that the visitors whose purpose of the visits are to purchase the products and to satisfy their interest in 'the events and contents of the events affect the interest and the repeat business deals of the visitors, among the interest and repeat business deals pursuant to the characteristics of the visitors. It has also been found that the visitors who have recognized the representative brands in the exhibitions affect the interest and the repeat business deals and the visitors who have visited the exhibition several times are more satisfied than the visitors who have visited the exhibition for the first time. The comparative evaluation of the degree of importance of the marketing activities of the participating companies before the visitors' visit to the exhibitions and the degree of satisfaction after their visit reveals degrees of satisfaction in the order of 'the booth staff's professional knowledge of the exhibits', 'foreign language proficiency and their techniques of negotiation and demonstration', 'designs of the exhibits (colors and packaging), 'prior publicity of the participating companies. Such being the case, the companies participating in any of the overseas should maximize the result of their participation in the exhibition by training their staff in the products and foreign languages and through the prior publicity. It has also been found out that "the atmosphere of the booth in the exhibition such as 'launching of new products', 'external appearances of the booth, layout of the interior facilities and the atmosphere and events of the participating companies affect the interest and repeat business deals of the visitors, among the factors for the satisfaction of the visitors. Therefore, it has been proven that the external factors such as the external appearances of the booth, display of the products, launching of new products and events producing the atmosphere of the booth of the participating companies among the marketing activities conducted by the participating companies, and the extent of the training of the booth staff and prior publicity are the major factors affecting the interest and repeat business deals of the visitors.

This research was conducted to provide basic document on efficient health promotion behavior program that elementary school students can use from elementary school course to enhance health promotion behavior for healthy life by checking out the degree of the most influential factor for health promotion behavior about elementary school students who establish lifelong health habit, and by checking out the relation between the degree of self-efficacy and health promotion behavior. The number of subjects of this research was 598. They were all elementary school students from the sixth grade students of the 5 cities of the Kyeong Nam province. We conducted questionnaires and did statistical analyses by using 592 papers which were suitable for date analyses with SPSS. The conclusions were as follows; A. The degree of self-efficacy The degree of self-efficacy of elementary school students was more than average. The degree of self-efficacy on physical activity was the highest and the degree of self-efficacy on self-fulfillment was the lowest. The degree of self-efficacy of girl students was comparatively higher than that of boy students. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest in health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. B. The degree of health promotion behavior Although the degree of health promotion behavior of elementary school students was a bit lower than the degree of self-efficacy, it was higher than average. The degree of health promotion behavior on physical activity was the highest. But the degree of health promotion behavior on health of their own was the lowest. The degree of health promotion behavior between girl students and boy students was the same. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest In health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. C. The relation between self-efficacy and health promotion behavior When the degree of self-efficacy was high, the degree of health promotion behavior was high too. So there was high positive relationship between self-efficacy and health promotion behavior. Physical activity showed the highest relationship. The order of strong relationship run as follows. Relationship with others, self-fulfillment, management of stress. The higher self-efficacy which was a recognizable factor on health behavior, the higher the degree of health promotion behavior. It is being revealed that many modem chronic diseases are cause by accumulated careless attitude on harmful health habit and lack of self-control. The behavior of keeping healthy and enhancing health is more firm when they have high self-efficacy which is believing their own conviction. So, When we teach elementary school students health promotion education at school, we should try to enhance their own self-efficacy rather than just instill simple information about health. By doing so, we can help them change their attitude on health. Then, they could enjoy life-long healthy life.

Community portraits can deeply explore the characteristics of community structures and describe the personalized knowledge needs of community users, which is of great practical significance for improving community recommendation services, as well as the accuracy of resource push. The current community portraits generally have the problems of weak perception of interest characteristics and low degree of integration of topic information. To resolve this problem, the reader community portrait method based on the thematic and timeliness characteristics of interest labels (UIT) is proposed. First, community opinion leaders are identified based on multi-feature calculations, and then the topic features of their texts are identified based on the LDA topic model. On this basis, a semantic mapping including "reader community-opinion leader-text content" was established. Second, the readers' interest similarity of the labels was dynamically updated, and two kinds of tag parameters were integrated, namely, the intensity of interest labels and the stability of interest labels. Finally, the similarity distance between the opinion leader and the topic of interest was calculated to obtain the dynamic interest set of the opinion leaders. Experimental analysis was conducted on real data from the Douban reading community. The experimental results show that the UIT has the highest average F value (0.551) compared to the state-of-the-art approaches, which indicates that the UIT has better performance in the smooth time dimension.

Increasing interest and providing educational experience for the public have long been a major ARt Museum goal. This interest raises the question of how visitors respond to museum exhibits. Much researches have been done which indicate the newer and more interactive exhibits are indeed more didactic and enjoyable than conventional exhibits. This study examined the effectiveness of art exhibits which display information about the creative process of developing a work art along with the final work of art to test if they results in more viewer interest and greater appreciation of the final work of art than those which display only the final work of art. In the early part of the 1991 spring, a counterblancing AB/BA quasi-experiment was carried out in the Jhnson Museum of Art, Cornell University. Methods used to collect and measure visitory interest and appreciation were unobtrusive observation and survey questionnaire. As the indirect measurement of visitor interest, attracting power and holding power were measured by unobstrusive observation of visitor time spent, while the direct measurement of visitor interest and appreciation, visitor's interest, understanding , and degree of favorableness were measured by survey questinnaire. Data analysis reached conclusion that the process approach fine art exhibit designs significantly resulted in more viewer interest and greater appreciation of art work than the conventional fine art exhibit design.
