The purpose of this study was to investigate the differences between male and female internet clothing purchasers in regard to value and clothing benefit sought. The subjects used for the study were 224 university students who purchased clothing products through internet. The value consisted of security, pleasure, and accomplishment factors. Clothing benefits sought had figure compensation, sex appeal & fashion, individuality, conformity, and comfort factors. The results showed that male and female internet purchased students differed in regard to value and clothing benefit sought factors. Specifically, male students considered pleasure value more important than did female purchasers. In the meanwhile, female students considered accomplishment value more important and sought figure compensation and conformity benefits more than did male students. Regarding the effects of value on clothing benefits sought. the achievement value had a positive effect on figure compensation, sex appeal & fashion, and conformity benefits for both male and female students. no Pleasure value also had a Positive effect on rigure compensation and sex appeal benefits for female students while it had no effect for male students. In addition, while the security value had a positive effect on conformity benefit for female students, it had a positive effect on comfort benefit for male students.

This study was initiated to develop a methodology for devising Korean virtual models for apparel shopping at internet shopping site. The data base for this study was the Korean National Anthropometric Survey in 1997. The subjects were 493 women and 626 men in 20's. The researchers also measured 88 males and females in age 20's to suggest back and front depth proportions which are not available from the survey. The virtual models' figure types were classified by the heights, drop value and bust(chest) girth. It was evaluated whether it is needed to separate figure type with bust(chest) girth. The body sizes of virtual models were suggested for side view model and front view model in 13cm height. Four female virtual models were suggested for front view and side view. Eight male virtual models were suggested for front view and side view. Each virtual model's height, breadth and depth proportions were calculated. Shoulder breadth. Bust(chest) breadth, waist breadth, hip breadth and proportions were calculated for front view model. The bust(chest) depth, waist depth, abdomen depth, hip depth and proportions were calculated for side view model. Height proportions were suggested for female and male virtual models.

The purpose of this study was to examine the appearance management behavior and its motives according to male consumers' age. A set of questionnaire was administered to 398 male consumers. Data were analyzed by utilizing frequency, factor analysis, ANONA, and Crosstabs. The results showed that factors of the appearance management behavior were classified into such as fashion oriented, figure management, figure improvement, skin care, cosmetic surgery, hair care, and health oriented. The male consumers age in the 20s, were more conscious of the appearance management. The male consumers aged over 40s were more aware of figure management and hair care for better health oriented. Appearance management behavior motives were classified into individuality, sociality, and interest arousal. Most of the male consumers showed higher interests in sociality among appearance management motives for better personal relations at workplace and increasing competitive edge.

This research aims to recognize necessity of modern expression of traditional pattern, understand the matter which is expressed when developing design using traditional pattern, and find the solutions. As the solutions, this research presents design of traditional pattern using symmetry concept and works on the possibility of symmetry as the pattern design. So this research carried out in-depth interview to textile designer working at Gyeongsangnam-do, analyzed the substances. The main results are as follows. First, the presented problems of developing common pattern design and designing using traditional pattern show the necessities for adequate harmony among conception of creative idea, traditional pattern and present pattern. As the solution, the efficient design principles are required. Second, the seven traditional figures can present design applying symmetry, also draw the 8 mapping models for the visuality and utilization. Third, the symmetry-applied traditional pattern design makes it possible for the traditional figure to be represented with the creative and modern sense and provides easier way to the design development by complementing the pattern design formation. As the result, symmetry-utilized traditional pattern design improvement shows the expectation that it will increase the design development ability and ease the figure drawing. In addition, the pattern development which can be applied to any figure presents the time efficiency as well as possibility of the high added value textile industry.

Heat emission from the laser diode used in the optical disc drive and the defects from the increased temperature at the system have attracted attentions from the field of the information storage device. Thermoelectric refrigerator is one of the fine solutions to solve these thermal problems. The refrigeration performance of thermoelectric device is dependent on the thermoelectric material's figure-of-merit. Meanwhile, high electrical contact resistivity between metal electrode and p- and n-type thermoelectric materials in the device would lead increased total electrical resistance resulting in the degeneracy in performance. This paper represents the manufacturing process of the PbTe-based material which has one of the highest figure-of-merit at medium-high-temperature, ~ 600K to 900 K, and the nickel contact layer for reduced electrical contact resistance at once, and the results showing the decent contact structure and figure-of-merit even after the long-term operation environment.

The purpose of this study was to provide basic information on the propriety of the ready to wear garment sizes of Tween Generation(ages from 5th grade to 8th grade) who has different clothing preferences in color, styles, and design and also different body sizes and shapes from younger and older students. The objectives of the study were to ascertain (a) the body figure changes occurring during Tween Generation; (b) the coverage of manufactures'garment sizes. The body measurements of elementary school students(5th & 6th grades) and junior high school students(7th & 8th grades) provide the basic statistics for this study. The mean differences of each size within each figure type are compared by using t-teats. The differences in various manufacturers'apparel sizing and figure size are investigated. Also the body measurements and the apparel sizes of the manufacturers are compared in order to evaluate the suitability of the garment size. Results indicate that the body type factors are different in each age group. And manufactures'sizes come out to be much smaller than the actual body measurements. Young casual wear can cover junior high school students satisfactorily but for elementary school students, because of low drop-value, the overall satisfaction with filling is low.

The characteristics of light in the paintings of Rembrandt van Rijn, Johaness Vermeer and Edward Hopper are very different. While Rembrandt and Vermeer lived in the 17th century, Hopper lived in the 20th century. Although this time gap, comparative study on their light-space relationship is important because there are spatial similarities as well as light differences. Most three painters' works depict interior spaces with one person inside. The interior space is filled with different light and shadow. In the Rembrandt's paintings, only part of the figure is lit in the ambiguous darkness. In the Vermeer's paintings, the soft indirect light is filled in the domestic space and the boundary between the figure and space is blurred. In the Hopper's paintings, the direct sunlight invades the interior and the figure confronts with strong daylight. These light differences were caused by the artists' intentions as well as the environmental situations. 4 case paintings of each artist were analyzed by phenomenological aspects and computerized light brightness test. Scale models were built to re-construct the three different light characteristics. The model experimentation will have potential to develop 2 dimensional art analysis into 3 dimensional space design by means of light. However it was very difficult to construct the three lights, the experimentation shows they have unique characteristics that can be applied to spatial design studies.
