The purpose of this study was to investigate the adolescents' images and preference on cultural products based on Baekje traditional culture focused on adolescents. The subjects were 421 adolescents in Daejeon and Chungnam province. The measuring instruments was stimuli of cultural products and a questionnaire with semantic differential scales of image of cultural products, preference, product evaluation criteria, and subjects' demographics characteristics. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, t-test, ANOVA, Duncan's multiple range test, and regression analysis using SPSS program. The results were as follows. First, 3 factors(attractiveness, interest, gentleness) were emerged on images of cultural products based on Baekje tradition culture, however, the current products could not convey affectively the attractive and gentle image of baekje traditional culture. Second, the preference of the Baekje cultural products was evaluated low, and especially design and price was rated low in the evaluation criteria. Third, preference was related with the 3 image factors, and attractiveness factor was showed highly positive effects on preference of cultural products. The implication of this study was to provide the useful cultural product development plan for adolescents, and the research results suggested that modern and individual design, unique traditional pattern, resonable price, and practicality have to be considered to develop successful cultural products for adolescents.

In Korea, the market size for environment-friendly agricultural products has reached a plateau, even though many Korean consumers still show a high level of preference for environment-friendly agricultural products. In order to solve this problem, some Korean farmers and marketers are starting to try to export their products to many countries, including China. China, in particular, is becoming one of the fastest rising market for Korean environment-friendly agricultural products, after the signing of the Free Trade Agreement with China. However, little research has been done or reported about the purchase behaviors of Chinese consumers. The purpose of this paper is to analyze the environment-friendly agricultural product purchase behavior (especially, mandarin orange and muskmelon) of consumers in the Chinese market and to present some useful implications for Korean farmers and marketers. Through survey in China (especially, Beijing and Shanghai) and frequency analysis, this study made the following findings: first, Chinese consumers show a very strong concern for environment-friendly agricultural products. Second, many Chinese consumers usually buy environment-friendly agricultural products more than two times per month. Third, Chinese consumers give more value to freshness and food-safety than taste when they make decisions on buying environment-friendly mandarin orange and muskmelon. These can have some implications for the exportation of environment-friendly agricultural products.

A computer-aided process planning system for rotationally symmetric deep drawing products has been developed. The application for non-axisymmetric components, however, has been reported yet. Therefore, this study investigates process sequence design in deep drawing process and constructs a computer-aided process planning system for non-axisymmetric motor frame products with elliptical shape. The system developed consists of three modules. The first one os a 3-dimensional modeling module to calculate surface area for non-axisymmetric products. The second one is a blank design module that creates an oval-shaped blank with the identical surface area. The third one is a process planning module based on production rules that play the best important roles in an expert system for manufacturing. The production rules are generated and upgraded by interviewing with field engineers. Especially, drawing coefficient, punch and die radii are considered as main design parameters. The constructed system for elliptical deep drawing products would be very useful to reduce lead time and improve accuracy for production.

Telomerase synthesizes telomeric DNA repeats onto chromosome ends de novo. Telomerase activation and telomere shortening in human somatic cells have been implicated in cell tumorigenesis and immortalization. In order to find the potential inhibitors against telomerase activitiy which can be used as potential anticancer agents, we screened about 100 kinds of natural products after partition into n-hexane, ethyl acetate and aqueous layers from methanol extracts. The inhibitory effects of these materials against telomerase enzyme activity were tested in 293T cell culture using telomeric repeat amplification protocol(TRAP). The incorporation of $\^$32/P-dGTP into amplified DNA was measured by adsorption to Whatman DE81 paper instead of using TRAP assay for screening the extracts of natural products. Strong effective compounds were not found in this study but DE81 filter spotting method may be a useful model for the screening. Some of the compounds which showed somewhat inhibitory effects had cytotoxic effects also.

The purpose of this study was to analyze the relationship between the product characteristics and spatial configuration in a retail store. This study utilized the analytical method of Space Syntax, and the software package used for the analysis was New-wave and Pesh. The qualitative study focused on the showroom of 'H INTERIOR', a leading furniture company in Korea, and examined the accessibility of the space. The result showed that the main accessible route was well established in the retail store, and more trendy and fashionable products were likely to be displayed in more accessible places. Also, the products in the selected showroom were arranged according to the pricing information, so that products with lower price were displayed in more accessible places. This study suggested that it be important to adequately and appropriately display the products in relation to the characteristics of products, and implied that the method of Space Syntax was useful to strategically evaluate the display in retail spaces.

Recommender systems help consumers to find the useful products from the overloaded information. Researchers have developed content-based recommenders, collaborative recommenders, and a few hybrid systems. In this research, we extend the classic collaborative recommenders by clustering method to form a hybrid recommender system. Using the clustering method, we can recommend the products based on not only the user ratings but also other useful information from user profiles or attributes of items. Through our experiments on well-known MovieLens data set, we found that the information provided by the attributes of item on the item-based collaborative filter shows advantage over the information provided by user profiles on the user-based collaborative filter.

Recently, Mining negative association rules has received some attention and proved to be useful. Negative association rules are useful in market-basket analysis to identify products that conflict with each other or products that complement each other. Several algorithms have been proposed. However, there are some questions with those algorithms, for example, misleading rules will occur when the positive and negative rules are mined simultaneously. The chi-squared test that based on the mature theory and Correlation Coefficient can avoid the problem. In this paper, We proposed the algorithm PNCCR based on chi-squared test and correlation is proposed. The experiment results show that the misleading rules are pruned. It suggests that the algorithm is correct and efficient.

Rice is one of the most important cereals in the world. Japanese people use about 9 million tons of rice per you. We use rice for cooked rice as staple foods and for processing, such as rice wine (sake), rice crackers and miso fermentation, etc. Palatability, eating quality, of rice is evaluated by the sensory test and various kinds of physicochemical measurements. Japanese National Food Agency started the storage of 1.5 million tones of rice in 1996. We carried out the storage test using high quality rices since 1995 until 1996. As indices for the quality deteriorations of rice grains during the storage, germination ratio, enzyme activities, fat acidity, physical properties of cooked rice were clarified to be useful. We applied colorimetric method for the measurements of fat acidities in the place of titration method. Processing suitabilities of rice differ depending on the products. Low amylose rice is more suitable for soft rice crackers and high amylose rice is preferred more for rice noodle. Pre-cooked rice products, such as frozen cooked rice, retort-pouched rice and aseptic rice, are increasing recently in Japan. In addition to above-mentioned physico-chemical tests, NIR spectroscopy,“Midometer”and“Taste sensor”are novel and useful to evaluate eating quality and processing suitabolities. Recently, rice wholesalers and retailers have been obligated to display the name of cultivar, location of cultivation and the year of production of rice grains which they sell by the Japanese Agricultural Standard Law (JAS). In order to detect the dishonest labeling of rice cultivars, we developed new cultivar identification method based on DNA polymorphism.

This paper is mainly interested in customer's(fan's) royalty to professional sports in sports industry. The royalty is studied with the royalty to several products and a service, so that we can obtain the comparison between both the former and the latter royalty. Interested professional sports, products and service are baseball, basketball, soccer, beer, cu, cola/cider, etc, and we will call each of them 'item'. The seven related hypotheses are considered. In hypotheses the dependent variable is royalty to nine items, and the independent variables are rune items, and customer's sex and major. For testing hypotheses, a questionaire is used, and reliability is checked with Cronbach's Alpha and correlation coefficients. For some items the royalty is significantly strong. Rather, even if some item has bad quality, it is found that customers can be royal to that item. We can identify some of those items through the results of this study. The strong significant results will be useful for the customer management. Additional studies are required for nonsignificant results which seems to be useful, and they are noted in the final part of the paper.
