초고분자량 폴리에틸렌(UHMWPE)섬유는 현재까지 알려져 있는 섬유중 비강도가 가장 우수하며 강도 또한 최고 40g/d를 나타내는 슈퍼섬유중에 하나이다. UHMWPE섬유는 비교적 간단한 분자구조로 이루어져 있으며 높은 결정화도로 인해 광 안정성 및 자외선 저항성이 우수하며 내마모성도 뛰어나다. 이러한 특성으로 인해 최근 로프 및 어망 등의 산업적 용도 뿐만 아니라 익스트림 스포츠웨어를 포함한 의류소재에도 다양하게 적용되고 있다. 하지만 의류소재 적용에 앞서 초소수성으로 이루어진 분자구조와 낮은 내열성으로 인해 염색이 쉽지 않으며 다양한 색상을 구현하기가 힘든 실정이다. 현재 본 연구실에서는 이와 같은 문제점을 해결하기 위해 UHMWPE섬유에 염색이 가능한 염료를 개발하였으며 보다 다양한 색상을 구현하기 위해 연구를 진행 중이다. 현재 본 연구실에서는 UHMWPE섬유 염색에 있어 Blue, Red, Yellow, Magenta 계열의 색상구현이 가능하며 보다 심색화 된 색상을 구현함으로 인해 의류용 섬유소재 및 산업용 섬유소재에 다양하게 적용할 수 있도록 UHMWPE섬유용 염료합성 실험이 진행되고 있다. 안트라퀴논 및 아조계 염료에 초소수성 알킬체인을 치환함으로써 염료의 소수성을 증가시켜 초소수성 섬유인 UHMWPE섬유에 염착성을 증가시키고 높은 견뢰도 결과를 확보하였다. 또한 내열성이 낮은 특성에도 불구하고 염색 이후 UHMWPE섬유가 가지는 물성에는 큰 변화를 나타내지 않았다.

By researching Western equestrian clothing, this study investigated the process in which styles of menswear are introduced into women's sportswear. In addition to women's equestrian clothing shown in paintings and illustrations kept in overseas museums, this study also analyzed books addressing 200 years of Western dress style history, from the late $17^{th}$ century to the $19^{th}$ century. The analysis data present the design characteristics of women's equestrian clothing according to different periods. A total of 21 works were used as research data: two from periods prior to the $17^{th}$ century, three from the $17^{th}$ century, ten from the $18^{th}$ century, and six from the $19^{th}$ century. The research results show that items of trendy menswear were commonly used in women's equestrian clothing during the late $17^{th}$ century - to be specific, in all forms of clothing worn on the upper body, including coat and cravat, tricomhat, and accessories. Women's equestrian clothing after the $18^{th}$ century took the form of menswear. However, the uniform was also generally worn with a fitted, tailored redingote on top of the robe, along with pants. In the $19^{th}$ century, women's equestrian clothing became longer in length, like men's styles. The uniform gradually lost volume, and the jacket became shorter and narrower. In addition, the drawers were replaced with pants that came down to the ankles, which were similar to men's trousers. Breeches also became knee - length, thus following the style of menswear. These results show that women's equestrian clothing, worn during horseback riding, a sport previously enjoyed by Western aristocrats, were similar to what men wore. Also, in contrast to the distinct differences seen between men's and women's daily clothing, the equestrian uniforms of women showed a tendency to follow the clothing style of men.

In this research, we have developed a ski-simulation system based on a physics-based simulation model using Newton's second law of motion. Key parameters of the model, which estimates skier's trajectory, speed and acceleration change due to skier's control on ski plate and posture changes, were derived from a field test study performed on real ski slope. Skier's posture and motion were measured by motion capture system composed of 13 high speed IR camera, and skier's control and pressure distribution on ski plate were measured by acceleration and pressure sensors attached on ski plate and ski boots. Developed ski-simulation model analyzes user's full body and center of mass using a depth camera(Microsoft Kinect) device in real time and provides feedback about force, velocity and acceleration for user. As a result, through the development of interactive ski-simulation motion recognition system, we accumulated experience and skills based on physics models for development of sports simulator.

For the purpose of examining the relationship of physiological and subjective responses to different exercise intensities and varied types of sportswear material, under environmental condition $20{\pm}1^{\circ}C$ $50{\pm}3%$RH, five men who wear four different kinds of sportswear which have same clothing cover area. The subjects exercised for 20 min with a 20 min pre-exercise rest period and another 20 min post-exercise recovery period. Throughout the 60 min. duration, we monitored the local skin temperature, rectal temperature, clothing microclimate and subjective sensation. The mean skin temperature was recorded to range from $33.5{\sim}34.1^{\circ}C$ for the entire duration of the experiment with the highest temperature observed at the 7th min after starting the exercise. During the exercise intensity at THR 20, the lowest recorded temperature was at the 5th min of the recovery time and stabilized at the 10th min. However, in the exercise intensity condition at THR 70, the temperature declined steadily until the end of the experiment. With regard to clothing materials, cotton 100% and Polyester/Cotton blended fabrics knit(35/65) was $0.5{\sim}0.7^{\circ}C$ maintained lower than Polyester 100% and polyester/Cotton blended woven fabrics (65/35). In the case of the rectal temperature at THR 70 in case of PET 100%, Polyester/Cotton blended woven fabrics (35/65) was higher $0.2{\sim}0.5^{\circ}C$ than other sportswear throughout the duration of the experiment.

The purpose of this study is to classify customer experience components using Bernd H. Schmitt's Strategic Experiential Modules and explore the relevance between fashion lifestyle and customer experience components. A survey was conducted on 400 adults between the ages of 20s to 50s who had experience in sportswear stores. The results obtained are as follows. First, according to fashion lifestyle, the respondents were divided into an individuality-valued pragmatic group, a trend-oriented brand-seeking group, a fashion-interested group, and a conservative pragmatic group. Second, customer experience components were divided into sensory experience, emotional experience, cognitive experience, behavioral experience, and relational experience. Third, on analyzing the relationship between customer experience and fashion lifestyle, it was found that a fashion-interested group has the highest value in all experiences; therefore, it can be considered that the higher the interest in fashion, the more important is the customer experience. On the other hand, the conservative pragmatic group represented generally smaller values than the other three groups in all customer experiences. Fourth, there were significant differences in the customer experience components that were considered to be important depending on the fashion lifestyle type. An individuality-valued pragmatic group valued cognitive experiences, a fashion-interested group valued all experiences, and a conservative pragmatic group showed low scores in all customer experiences. The results of this study will allow companies to build more customer-friendly experiences and enable consumers to engage in satisfactory purchasing activities through better customer experiences.

This study explored the relationship between Generation MZ female consumers' participation in sports activity, consumption of body-exposing sportswear, body-esteem, and appearance management behavior. In-depth interviews were conducted with twenty Generation MZ female consumers who regularly participate in sports activity and consume body-exposing sportswear. Based on transcriptions of in-depth interviews conducted with research subjects, the researcher and two assistant researchers collectively categorized and compared common characteristics found in their responses, categorized according to themes using units of words/terms and paragraphs. The main finding were as follows. Firstly, Generation MZ female consumers participated in various sports activities for an average of approximately one hour, three times per week. The effects of such participation were improvements in physical and psychological health. Secondly, Generation MZ female consumers considered aesthetical, functional, and economical factors when they consumed body-exposing sportswear, regardless of the activity in which they participated. This sportswear served to increase the efficiency of exercise and also played a motivational role. Thirdly, the overall body-esteem of Generation MZ female consumers who participated in sports activity regularly and consumed body-exposing sportswear was high. Fourthly, Generation MZ female consumers who regularly participated in sports activity and consumed body-exposing sportswear were practicing active appearance management behavior in order to show how their body had been shaped by sports activity. In addition, they were pursuing four self-images: "polished image pursue", "self-care image pursue", "natural image pursue", and "trustworthy image pursue".
