Recent rapid development of computer, information communication and Web service technologies is exerting considerable effects on all industrial areas. As such digital technologies are also introduced to the clothing and fashion industry and create 'virtual garment environment' consisting of 3D virtual bodies, virtual garments and virtual try-on systems, consumers are now able to try virtual garments on their virtual body online. This study was conducted in order to analyze consumers' tendency of clothing purchase using 3D virtual simulation technology, which is increasing attention throughout the world, and to propose strategies on the development of virtual try-on technology for activating apparel online shopping. The subjects of this study were men and women aged 18 or older living in the North Carolina State, U.S., and a questionnaire survey was conducted with them on their tendency of apparel online shopping and their preference for real garments and virtual garments. According to the results of this study, consumers' awareness of apparel shopping using virtual try-on was still low. Moreover, in the results of surveying consumers' purchase preference for real garments and virtual garments, preference was highest for real garment (P), which was followed by virtual garments OA, OB and BB. Based on the results of this study, for the activation of apparel online shopping using virtual simulation technology, it is considered necessary to provide services implementing virtual try-on similar to consumers' actual try-on. This requires further active research and technology development on virtual try-on simulation using digital technologies.

The purpose of this research was to investigate the difference in fabric preference of formal wear attire between the Korean and American female consumers. For such purpose, fabrics which were used in the womens formal wear market of Korean(n=25) and U.S.A.(n=25) in the 1999 spring/summer season were collected from different fabric converters of the two countries. The respondents were comprised of 50 Korean and 50 U.S.A. female volunteers in the age group of 20s and 40s. A 5 point Likert Scale was used to evaluate the degree of the \"like\" preference of fabrics. T-test and Spearmans rho statistics were conducted for data analysis. The followings are the results. 1. Korean 20s and American 20s preferred Korean fabrics but Korean 40s and American 40s preferred U.S.A. fabrics. 2. Generally, the 20s preferred greyish or tone down color, whereas the 40s preferred both greyish and colorful fabrics. 3. Koreans preferred melange colored fabrics as well as solid color fabrics. 4.

BACKGROUND/OBJECTIVES: Veggiecation was developed to improve children's vegetable consumption through classroom lecture and cooking activities. In this study, we explored potential determinants of vegetable consumption behavior and intention, and examined the impact of Veggiecation on vegetable consumption behavior, intention and personal factors among Korean children. SUBJECTS/METHODS: The 4-week Veggiecation program was implemented for second-graders in South Korea (35 children in the intervention group, 36 in the control group). We identified personal and environmental factors influencing vegetable consumption behavior and intention using multiple regression analyses. Consumption behavior, intention and, personal factors such as preference, attitude, and self-efficacy were compared between the groups before and after the intervention. RESULTS: Children's vegetable consumption behavior was significantly correlated with personal, social-, and physical-environmental factors as well as intention. Among the variables, preference was the most influential factor on intention, and attitude and intention had great influence on the behavior. After the program, children in the intervention group demonstrated significant improvements in vegetable consumption, intention, attitude, preference, and self-efficacy compared with children in the control group. CONCLUSION: Veggiecation, a school-based culinary nutrition education program, improved vegetable consumption and intention, as well as preference, attitude, and self-efficacy, in second-graders. Veggiecation has great potential, as a global program, to increase children's vegetable consumption. This program can be expanded through various channels, such as after-school programs or camps, to provide a positive impact for children.

SP 데이터는 데이터 수집의 효율이 RP 데이터 보다 높고 장래의 교통 시스템의 조건이나 속성에 대한 응답자들의 태도를 조사 할 수 있다는 점에서 많이 사용되고 있으나 SP 데이터는 주요하게 두 가지 편위를 가지고 있는데 SP 설문조사시에 발생하는 응답편위와 SP 패널조사시에 발생하는 누락편위이다. 이러한 SP 데이터의 편위가 수정되지 않으면 장래의 잘못된 교통수요예측을 유발할 수 있다. 따라서 본 연구에서는 이러한 SP 모델의 편위와 상태의존을 고려한 모델을 구축하기 위하여 6개의 횡단면 모델과 동적모델을 제안하였다. 횡단면 모델 중 RP데이터의 선택결과를 고려한 모델을 이용하여 SP모델의 편위를 보완할 수 있는 모델을 구축할 수 있었으며 동적모델의 경우에 패널데이터의 상태의존도를 지수함수로 가정하여 상태의존도를 고려한 동적모델을 구축하였다. 또한 패널조사시에 필연적으로 발생하는 누락데이터에 의한 누락편위를 모델에 고려하기 위하여 WESML방법을 적용하여 모델을 구축하였으며 그 결과 상태의존도를 보다 세밀하게 제어함으로서 모델의 설명력을 개선시키고 향후 SP 패널데이터를 이용한 동적모델의 적용성을 높일 수 있음을 알 수 있었다. 본 연구에서는 모델의 유용성을 검토하기 위하여 전주시의 외각 지역인 호남제일문 방향에서 도심으로 접근하는 3개의 주경로(천변로, 기린로, 팔달로)에 대한 패널조사 자료를 바탕으로 모델을 구축하였다.

A Variable Structure Model Reference Adaptive Controller (VS-MRAC) using state Variables is proposed for single input multi output systems. . The structure of the switching functions is designed based on stability requirements, and global exponential stability is proved. Transient behavior is analyzed using sliding mode control and shows perfect model following at a finite time. The effect of input disturbances on stability and transients is investigated and shows preference to the conventional MRAC schemes with integral adaptation law. Sliding surfaces are independent of system parameters and therefore VS-MRAC is insensitive to system parameter variations. Simulation is presented to clear the theoretical results.
