Fur garment has long been the conventional symbol for luxury, or conspicuous consumption. However, as fashion items began to diversify as part of overall fashion trend, fur items are now more about individual taste and style than just lavishness. Synthetic fur is especially emerging as a new promising fashion material, with a touch almost like natural fur at an affordable price. Along with the emergence of 'Vegan Fashion' trend, synthetic fur is establishing itself as a popular fashion textile. This study is an attempt to investigate subjective evaluation and physical properties of natural and synthetic furs, whose results will further serve as basic data in developing synthetic fur materials. Sensory and emotional evaluations are carried out on natural and artificial furs. For analysis, factors such as weight, thickness, air permeability, gloss and compressibility were surveyed to observe how they influence the physical properties. According to the subjective evaluation, natural and artificial fur samples do not differ in conspicuous ways in appearance. Experiments on physical properties, specifically warm/cool touch experiment, show that natural fur has a slightly higher warm sensation than artificial fur. Luster analysis by using a microscope revealed that there are subtle qualitative differences between natural and artificial fur. During the subjective evaluation, subjects found it hard to state distinct quantitative differences in luster. A survey as a means of assessing qualitative differences in gloss seems to be necessary to complement the evaluation. Results from this study will potentially serve as resources for diversification of fashion product designs using synthetic fur.

This study tries to search and analyze empirically the clothing merchandise purchase motivation and behavior made by foreign visitors who bought clothes as tour memorials in South Korea. To make a empirical study we made survey research and evaluated 30 items for the survey of clothing purchase motivation and 25 items for the survey of the importance and satisfaction revealed at the time of purchase with the standard of Likert 5 point. We had chosen 614 sample participants including 176 English speakers, 211 Japanese speakers, and 277 Chinese speakers among those foreign tourists who had purchased clothing materials at the Dongdaemun Shopping Mall. The result of analysis is as follows : As the result of factor analysis about the clothing merchandise purchase, we had 6 factors. They are (1)impulse, (2)utility, (3)fashionableness, (4)tour commemoration (5)psychology (6)economy. As the result of cluster analysis based on the standard of selected 6 factors of clothing merchandise purchase motivation, we could divide three groups such as (1)the pursuit type of clothing merchandise purchase, (2)the pursuit type of recreation of feeling (3)the pursuit type of tour memorial. As the result of analysis on the items of purchased clothing merchandise, the highest frequency of purchase was made by T-shirt, then by the order of sweater, blouse, and aloha shirt, pants, and jacket. In regard to the importance of items related to clothing merchandise, the highest importance was made by design, then by the order of price, size, color and utility, and style. In regard to the items related to the service of shopping mall, the highest satisfaction was made by the convenience of business hour. Meanwhile, the lowest satisfaction was made by the inconvenience of fitting room, the speaking and by ability of foreign languages by sales agents.

Finite element analysis(FEA) has been extensively applied in the analyses of biomechanical properties of stents. Geometrically, a closed-cell stent is an assembly of a number of repeated unit cells and exhibits periodicity in both longitudinal and circumferential directions. This study concentrates on various parameters of the FEA models for the analysis of drug-eluting biodegradable polymeric stents for application to the treatment of coronary artery disease. In order to determine the mechanical characteristics of biodegradable polymeric stents, FEA was used to model two different types of stents: tubular stents(TS) and helicoidal stents(HS). For this modeling, epigallocatechin-3-O-gallate (EGCG)-eluting poly[(L-lactide-co-${\varepsilon}$-caprolactone), PLCL] (E-PLCL) was chosen as drug-eluting stent materials. E-PLCL was prepared by blending PLCL with 5% EGCG as previously described. In addition, the effects of EGCG blending on the mechanical properties of PLCL were investigated for both types of stent models. EGCG did not affect tensile strength at break, but significantly increased elastic modulus of PLCL. It is suggested that FEA is a cost-effective method to improve the design of drug-eluting biodegradable polymeric stents.

The wear and abrasion mechanism of conventional PET/Cotton fabric which is used as a lining layer for thermotherapy massager was elaborately investigated in order to increase the life-span of the fabrics for Thermotherapy Massager. Based on the destruction mechanism, the feasible PET fabrics were prepared and its anti-wearing performance was evaluated. It is revealed that the wearing destruction is mainly caused by the repeat abrasion on a specific part of folded fabric as well as abrasion itself. Therefore, it is necessary that the prevention of fabric folding while massager is running is essential and the recovery from the crease on a fabric is also necessary to solve this problem. Covered elastic yarn, high twisted yarn, change of fabric structure or different fiber were utilized to prepare the possible alternatives. As a result, the anti-wearing performance of the fabrics are greatly improved to have about 2 times and 1.5 times longer life-span for the fabric with covered elastic yarn and high twisted yarn, respectively.

The purpose of this study is to find at the basic data for the appropriate conditions of the pillows for the Koreans. In this study, the origins, materials, the forms and the sizes of Korean pillows have been investigated by means of existing remains and the existing documentary records. The results are as follows : 1) We can infer that ordinary pillows have already been used in a period of the three kingdoms, because the pillows for the dead bodies been unearthed from the tombs of this period. 2) Round pillows which are used nowadays to rest our heads have also been utilized as early as in Koryo Dynasty or even in the previous period. It is because the pillows described in Koryo dakeyung are similar to the present round ones. Most of the existing Koryo pillows have been made fo ceramics. Their average length is 20.0$\pm$5.4cm, the average low height is 9.7$\pm$0.9cm, and their average high height is 11.8$\pm$1.2cm. 3) The material which has been used to make pillows in Choson Dynasty is various : textile, wood, rush, bamboo, ceramics, etc. Most of them have been made in a round form or in a form of lying square. The average low height of lying squares is 8.1$\pm$2.5cm. The average high height is 11.9$\pm$1.9cm, and the average lenght is 19.0$\pm$5.6cm. The average diameter of embroidered pads attached to both sides of round pillows or the average length of one side of regular squares is 12.5$\pm$2.3cm.

The present study was conducted to devlop and appropriate retirement home model for the elderly in terms of clothing and textiles; nutrition, health, and foodservice; housing and environment; and psychological adaptation. Specifically, the purposes of the study were: 1) to provide basic guidelines for clothing by comparing the clothing behavior of the elderly living in the retirement home and those living in their own homes with family, 2) to provide basic guidelines for balanced diet and effective foodservice, 3) to develop an ideal life space and facilities, and 4) to assess the psychological characteristics of the elderly. Questionnaires, observation, experimental method, and survey of literature were used for the study. Clothing behavior showed that the elderly were much concerned about clothing, and they preferred comfortable as well as fashionable designs. The elderly in the retirement homes complained of a lack of quantity and variety in clothing. They preferred natural fiber rather than blended fabrics. Flame resistance, thermal insulation, and flexibility of textile fabrics were found to be prime considerations in manufacturing and selecting clothing materials for the elderly. The health status of the surveyed elderly was generally good, but some poor eating habits were observed. Dietary nutrients intakes were generally sufficient, but several nutrients intakes were insufficient. The level of equipment in the kitchens of the institutions was low. Furthermore, the employment rate of dietitians in institutional settings was extremely low. This resulted in a lack of systematic foodservice management. Residents in the institution were generally satisfied with present life space and facilities but this was mainly because of abandonment, adaptation, and past experience. Optimal allocation of residents per bedroom and an adequate design for storage, bathroom, utility room, and dining room were recommended. The comparison of psychological status of the elderly living at home was more stable than those living in an institution. The emotional state of the elderly living in the institution was characterized by loneliness; they did not have close interpersonal relationships or future plans. An appropriate model for the elderly was developed on the basis of these findings.

We present a cloth simulation technique that is very stable yet also responsive. The stability of the technique allows the use of a large fixed time step when simulating various types of fabrics and character motions. The animations generated using this technique are strikingly realistic. Wrinkles form and disappear in a quite natural way, which is the feature that most distinguishes textile fabrics from other sheet materials. Significant improvements in both the stability and realism were made possible by overcoming the post-buckling instability as well as the numerical instability. The instability caused by buckling arises from a structural instability and therefore cannot be avoided by simply employing an implicit method. Addition of a damping force may help to avoid instabilities; however, it can significantly degrade the realism of the cloth motion. In this paper, a new buckling model based on immediate buckling assumption is proposed. A cloth element is assumed to reach a stable configuration immediately once it begins to buckle. This assumption makes it possible to simulate the fabric buckling stably without introducing any fictitious damping force. Consequently, it produces highly responsive cloth motion as well as improves the stability by modeling the fabric-specific buckling property adequately.

This study attempted to investigate present condition and product planning of global eco-fashion brands that harmonize fashion and sustainability. As research subjects, this study selected 97 oversea fashion brands mentioned in books related to eco-fashion, Black(2011), Brown(2010), Fuad-luke(2009). As for research methods, materials and ethical practices of these selected 97 brands through literature data and their internet site homepages. This study analyzed oversea eco-brands collected 26 British brands, 22 American brands, 36 European brands such as Germany, France, Italy, Sweden, Spain, Finland and so on, except Britain and 13 other regions including Japan, India, Canada, Mexico, and New zealand. In conclusion, the product planning characteristics of these oversea eco-fashion brands can be summarized as follows; community and fair trade, ecological and slow design, recycle, reuse, redesign, and new eco-models. Firstly, brands of 'community and fair trade' manufactured products through fair trade and local community's artisan by ethical practices with organic fabrics. Secondly, brands of 'ecological and slow design' pursued timeless design and multi-functional design as luxury eco-fashion styles. They used organic textiles, hemp, bamboo, soya, tencell, sea cell, and self-sustaining plants. Thirdly, brands of 'recycle, reuse, redesign' aimed for upcycling high-end fashion and used vintage clothes, textile scraps, PET, parachutes, tires, safety belts, advertising banner and so on. In addition, brands of 'new models as eco-fashion' suggested zero-waste cutting, recycling over-printing technology, new sustainable business model, and ethical practices in the supply chain of the fashion industry.

Exoticism, by definition, is 'the charm of the unfamiliar', usually because of associations with a distant country. In the western-centric world, exoticism implies non-western or oriental style. The purpose of this study was to identify Koreans' perception of "Exoticism", and to compare the perception of exotic fashion image according to gender and education differences. Empirical study was composed of two parts focusing on gender and education effects respectively. For the first part, data were collected by self-administered questionnaires distributed to 280 respondents at 2 universities and 2 high schools during August and September 2005. The sample was consisted of 140 male and 140 female. A measurement, including 24 image adjectives to evaluate 16 fashion stimuli, was developed. Data were analyzed by descriptive statistics, correlations, t-test, and MDS. There was no difference in the perception of exotic fashion image according to gender. Both gender groups perceived exotic image as western image and non-exotic image as oriental image. Thus it could be said that Koreans perceive western-based fashion as foreign and exotic. This finding implies the relativity of "Exoticism." In the second part, the measurement and the analysis methods were the same with the first part. The respondents were consisted of 70 fashion majored female students and 70 non-fashion majored female students. There was considerable difference between fashion and non-fashion major groups in their perception of exotic fashion image. Whereas non-fashion major group perceived exotic image as western image and non-exotic image as oriental image, fashion major group perceived exotic image as both western and oriental image. This result suggested that fashion major group have western-centered conception as well as general perception character of Korean.
