Ginsenosides are the major active ingredients in ginseng used for human therapeutic plant medicines. One of the most well-known probiotic bacteria among the various strains on the functional food market is Lactobacillus rhamnosus GG. Biocatalytic methods using probiotic enzymes for producing deglycosylated ginsenosides such as Rd have a growing significance in the functional food industry. The addition of 2% cellobiose (w/v) to glucose-free de Man-Rogosa-Sharpe broths notably induced β-glucosidase production from L. rhamnosus GG. Enzyme production and activity were optimized at a pH, temperature, and cellobiose concentration of 6.0, 40℃, and 2% (w/v), respectively. Under these controlled conditions, β-glucosidase production in L. rhamnosus GG was enhanced by 25-fold. Additionally, whole-cell homogenates showed the highest β-glucosidase activity when compared with disrupted cell suspensions; the cell disruption step significantly decreased the β-glucosidase activity. Based on the optimized enzyme conditions, whole-cell L. rhamnosus GG was successfully used to convert ginsenoside Rb1 into Rd.

Surrealism, appeared in the beginning of the 20th century and affected almost all art fields, is one of the most representative art trends. Surrealism, not restricted from any rules and traditions but tried to produce a new appreciations in the world of dream and unconsciousness, also has affected fashion. In this paper, I have tried to find out how the surrealism has been expressed in the modern fashion, especially in Thierry Mugller's design. Thierry Mugler is one of the most famous designers who have expressed surrealism in their fashion designs. I have classified his designs and researched them by the application into the human body and the nature, by the metaphor and transformation of things, and by the metamorphosis of location and an optical illusion. It was based on Depaysement which is one of the ways in surrealistic expressions. The result of the study is followings; First, surrealism made fashion design possible to creat unlimitedly and sublimated it anew modern beauty by attempting the varieties of the fashion, not restricted from any rules and traditions. Second, surrealism made the general public to complete anew recognition and valuation about fashion by expressing the external character and the internal meaning on the clothes. Third, surrealism made people to recognize, which clothes is not simply wearing thing but also one of the art expression forms.

This program aimed at preparing the pre-service teachers to teach about North Korean family life culture to secondary school students, by promoting the understanding and acceptance of cultural differences between the two Koreas. Based on the literature review, the educational contents were developed to reflect general aspects of North Korean family life. The program was implemented with 35 undergraduate students in a home economics teacher education program. The program consists of 15 units of 150-minute instructional sessions. The first three introductory sessions dealt with the definitions of family life culture and multiculturalism, as well as a historical review of South-North relationship. The following nine sessions were devoted to North Korean family life culture in five different domains: consumption and leisure, family and child-caring, food and dietary life, housing and neighborhood life, and clothing/fashion. During the final two weeks, pre-service teachers conducted mock-teaching. For evaluation, pre- and post-session scores on general teaching efficacy and understanding of cultural differences were compared using paired t-tests. The pre-/post-test results confirmed that the program was successful in promoting the understanding and acceptance of cultural differences between two Koreas of pre-service teachers.

The automatic drafting of clothing patterns can be realized through an Apparel Cad System when the clothing pattern has a pattern expression in human dimensions. However, it is difficult to apply automatic systems because it is difficult to express the ready-to-wear of various complex designs with one system. This study develops ready-to-wear patterns in an automatic drafting style and also develops nude patterns with human dimension-based drafting styles that can be applied to enable the setting of margins by design. For this purpose, radial body length measurement items and measurement methods were newly defined for female standard dummy and nude pattern systems. The institutional program was developed through the principle of a nude pattern system which is different from the pattern system of the existing system. The nude pattern developed in this study represents a basis and framework for the gradual transformation of the production pattern into the automatic system of the future and as a pattern having an institutional formula based on human dimensions.

A conceptual framework, based on a curriculum model of family life education content, and on a schema for analyzing explicit use of theory, was developed to discern the substantive themes of programs and the role of theories in publications on programs for families in the Korean family studies literature. Seventy two journal articles published between 1990 and 2002 were analyzed. The results revealed that the Korean family life education programs dealt with the breadth of topics, but most particularly internal family dynamics and interpersonal relationships, and utilized theoretical concepts as input and output in a different level: explicit, implicit, or no use of theories. Implications for future research and practice in Korean family life education are discussed, including gaps in the substantive foci of programs, and aligning programs more closely with theory.

The currently used personal color analysis is mostly based on Westerners' skin colors. As a result, the suggested colors are often not suitable for Korean people's skin colors. Accordingly, the purpose of this study is to develop 'Personal Color Design System(PCDS)' that can suggest fashionable colors suitable for Korean skin colors and personal color types. For this, the system was verified by customers testing and questionnaires, while the system modification and complementary measures were conducted.

A potentiometric flow injection biosensor for the analysis of anti-cholinesterases (anti-ChEs), based on inhibition of enzyme activity, was developed. The sensor system consists of a reactor with acetylcholinesterase (AChE) immobilized on controlled pore glass and a detector with an $H^{+}-selective$ PVC-based membrane electrode. The principle of the analysis is based on the fact that the degree of inhibition of AChE by an anti-ChE is dependent on the concentration of the anti-ChE in contact with AChE. The sensor system was optimized by changing systematically the operating parameters of the sensor to evaluate the effect of the changes on sensor response to ACh. The optimized biosensor was applied to the analysis of paraoxon, an organophosphorus pesticide. Treatment of the inhibited enzyme with pyridine-2-aldoxime fully restored the enzyme activity allowing repeated use of the sensor.

This study examined young children's beliefs about trait stability based on trait type and valence. Participants included 120 children (40 three-year-olds, 40 four-year-olds, and 40 five-year olds) recruited from 3 day-care-centers and 1 kindergarten in Seoul and Kyung-Ki province. Results revealed that young children's understanding of traits differed based on trait type and valence. Children demonstrated a strong belief that social-intention traits are more stable and harder to change when compared to internal-state traits. Young children's beliefs on trait stability were also strongly influenced by trait valence. They believed that negative traits are more likely to change for the better while positive traits have greater stability and are less likely to change over time.

The purpose of this study was to review university students' attitudes towards value-based consumption and their influences on it to the types of LOHAS lifestyle. The statistical analysis was based on a questionnaire survey by 275 subjects. Several attitude variables included in the study such as 'attitudes toward LOHAS lifestyle', 'environment', 'charity', 'need of business ethics', 'investment into socially responsible business', and 'good consumption'. By the results of the study, first, students' attitudes and concerns about the environment were positive, however, not expanded to the absolutely positive attitudes for their future society. Second, there is no clear relationship between their participation in the community and their attitudes to the LOHAS lifestyle. Third, university students' consumption was not based on the values of LOHAS, but on the attitudes to their own well-being. Fourth, groups with lower income and with no religious tendency revealed more positive attitudes toward LOHAS lifestyle than other groups. Fifth, there are some relations between LOHAS lifestyle and the individual's economic role performances such as the attitudes to 'environment', 'charity', 'need of business ethics,' 'investment into socially responsible business', and 'good consumption'.

The purpose of this study was to identify the effect on the evaluation or a female teachers' role-performance based on appearance according to backgrounds of students and their parents. For this study, data was collected between October 19 and 29, 2005 by means of a questionnaire designed to gauge a subject's evaluation of a teacher's abilities in learning guidance, living guidance, and human relations. The researchers selected two middle schools and four high schools in the city of Gwang-ju. The 398 surveys completed were analyzed using factor analysis, one-way ANOVA, Duncan's multiple range test, t-test and descriptive statistics. According to the study, the evaluation of a female teacher's abilities varies with the backgrounds of both students and their parents. Among the students tested perceptions were affected by gender, grade level and type of school attended. For mothers there were differences based on age, occupation and family income.
