This study proposed a method to apply certain fuzzy-related Quality control concepts to design customer-oriented products considering user requirements and information starting with the product development stage. This approach showed how to define the importance level of design elements and how to Quantify complex subjective perception of products using the fuzzy linguistic rating method and quality function deployment concepts. Using this approach, various customer requirements could be interpreted and reflected on the early design phase of a new product. To validate the proposed method, an experiment was conducted for designing the shape of the beeper using 14 subjects and 10 commercial beeper products. Front area, width/length ratio, thickness, curve variance, weight, and display area were selected as design elements of the beeper. The results showed that among design elements, front area and weight are significantly related with the subjective perception of the products. Consequently, this study indicates that customer decision on product selection could be made by quantification of user perception for beeper products.

We show that certain polygonal products of any four groups, amalgamating central subgroups with trivial intersections, have Property E. Using this result, we derive that outer automorphism groups of polygonal products of four polycyclic-by-finite groups, amalgamating central subgroups with trivial intersections, are residually finite.

Using a qualitative method, this paper described briefly the well-being-oriented consumers consciousness toward sustainability concept. The paper identified the major obstacles facing well-being society as evidenced by consumers own experiences for consuming products which are meet the necessity for environmental preservation. Over seventy percent of respondents who had a experience consuming the sustainable products said that they consumed it for themselves and their family's health of all things. Beside their interests about health, they made mention of the safety of sustainable products, high quality of sustainable products, to preserve our environment, confidence in sustainable products, encouragement from others, and curiosity for sustainable products. The respondents who did not consume the sustainable products argued that high price of sustainable products, genuineness of sustainable products, lack of information about sustainable products, unconcern about sustainable products, and difficulty to access to sustainable products were not allowed them from consuming the sustainable products.

The purposes of this study were to develop cultural fashion products using Baekje traditional culture, and to examine the effects of product image and evaluative criteria on the purchase intention of cultural fashion products using Baekje traditional culture. The subjects were 500 adult consumers from their 20s to 50s. The research method was a survey, and the instruments were four stimuli, which were developed using Baekje traditional culture, and the questionnaire, consisted of product image, evaluation criteria, purchase intention of cultural fashion products, and the subjects' demographic characteristics. For data analysis, descriptive statistics, Cronbach's α, factor analysis, and regression analysis were performed. The results of this study were as follows. First, four handkerchief designs were developed as cultural fashion products, based on the results of a preliminary investigation of consumer behaviors toward cultural fashion products and thier preference of Backje relics. Second, three factors (attractiveness, uniqueness, and gentleness) emerged for images of cultural fashion products. Third, four factors (design characteristics, tourism characteristics, cultural symbolism and practicality) emerged for the evaluation criteria for cultural fashion products. Fourth, three image factors had significant positive effects on purchase intention. Especially, attractiveness had a greater effect than others. Fifth, the four evaluative criterion factors also had significant positive effects on purchase intention. Design characteristics had the greatest effect, followed by tourism characteristics, cultural symbolism, and practicality in order.

Storytelling, a medium that arouses the customers' purchasing need by playing on their emotions, is the best content that can be used as it can increase the value of goods using information. This paper's significance is that it suggests cultural products that can be used by using Baeke relic Jinmyosu (Guard Animals) as a motif. The purpose was to present the possibility of high value-added cultural products using storytelling techniques. This study developed storytelling by adding the meaning of Jinmyo and Beoksa, who calm protected their masters from evil forces with horns and wings, and has the meaning of ascending into heaven and guiding the soul on the right path. That image gives a glimpse of originality and differentiation to Baekje. This study proposed 4 cultural products as 'Keeper Stone Mason' and 4 'Stone Mason Teller.' The proposed cultural products can help to give correct awareness of Baekje culture through a correct understanding of the historical significance of the Baeke relic, Jinmyosu. Moreover, it will help promote the originality and excellence of Baekje culture around the world by enhancing the value of Baekje culture. This study is expected to be used as a guideline for further research on developing cultural products that can create added value in various fields.

The purpose of this study is to improve ubiquitous fashion design which adolescents can be satisfied with. The methods of this study are documentary research of previous studies, survey research and deep interviews. For this study 371 students are selected as samples of survey. As a result of this study, we could know that the adolescents of the 21st century are enjoying actively the culture of consumers and the culture of information era. Domestic adolescents have much knowledge and interest in information and in UFC fashion products. So we can predict that domestic adolescents' interest and desire of UFC fashion products will increase gradually. As for using occasions, adolescents will use UFC fashion products for 'mobile', 'exercise', 'social followship', and as for using purposes, they will use UFC fashion products for 'listening to music', 'playing games', 'communication', 'search for information', etc. So when we develop UFC fashion products for adolescents, we'd rather develop the products for entertainment than for studying. To satisfy the various tastes of adolescents, UFC fashion products must also consider the design factors like styles, colors, materials, etc. In conclusion all UFC fashion products for adolescents must have not only the basic qualities like functions and conveniences, but also the qualities of designs.

Gardeniae Fructus is consisted of geniposide and it's derivatives. For the purpose of treatment of skin disease, geniposide and hydrolyzed products (HP) of Gardeniae Fructus were studied on skin permeation and cross1inking with biological tissue. The hydrolyzed products (HP) and active ingredients of Gardeniae Fructus were identified and investigated about skin permeability. Genipin has provided low cytotoxic cross1inking reagents and formed stable and biocompatible crosslinked products. The permeation enhancing effects of geniposide and genipin under the hydrolyzed products of cream and hydrogel preparations were tested using Franz type diffusion cell and the skin of hairless mouse. The remaining proportions of geniposide and genipin were measured in the hydrolyzed products of cream and hydrogel preparations. The crosslinking of epidermic and endodermic tissue with genipin under the hydrolyzed prodcuts of cream and hydrogel preparation was observed using light microscopy. Increased absorption ratio of the skin of hairless mouse about genipin was higher than that of geniposide. Loads at break, tensile strengths and skin permeation rate of the hydrolyzed products (HP) of cream and hydrogel preparations were higher than the nonhydrolyzed products (NHP). The hydrolyzed products (HP) of cream and hydrogel of Gardeniae Fructus Extracts were proper preparations and crosslinking agents to increase the transdermal absorption with epidermic and endodermic tissue.

To provide rice products in substituted for wheat flour and wheat products in elementary school foodservice, the survey for nutritionist in elementary school was accomplished from November 3rd to 8th, 2012 in Gwangju and Jeonnam area, and obtained 83 and 95 copies from Gwangju and Jeonnam, respectively. Most nutritionists were graduated from universities and had careers longer than 15 years. The nutritionists (56.7%) had worked at the schools where food allergy students were enrolled. The consumption of wheat flours per one student per month was 677.8 g in Gwangju and 707.4 g in Jeonnam. Udon and Jajangmyeon were more popular wheat products. Nutritionist agreed positively that rice products instead of wheat products were possible to use for meal menu (73.5% in Gwangju and 61.1% in Jeonnam). The frequent use of rice products was tteokbokkitteok, because of students' preference. The rice bread and tteokguktteok were preferred significantly higher in Jeonnam than in Gwangju. The advantages of rice products which perceived by nutritionists were benefits for health, digestive easily, and high nutritious, but their disadvantages were hard-to-find and expensive. The nutritional values of rice and recipes for cooking rice products were required as educational program for increasing consumption of rice products. Demonstration for rice cooking methods was selected most popular program. The application of rice products for school foodservice was preferred to Jeonnam compared to Gwangju (p<0.001). As a consequence, the nutritionists working in elementary school in Gwangju and Jeonnam area have positive thought about using rice products in school foodservice, if educational program of school foodservice menu using rice products should be demonstrated them.

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.
