This study aims to verify the sewing technology and the expression of the virtual garment program by comparing the appearance similarity between the real and the virtual power shoulder jacket. To this end, the H and the X silhouettes of the power shoulder jacket were selected as the reference designs. After making the reference designs into real jackets by applying the human body dimensions of women in their twenties, virtual avatars and jackets were produced using CLO 3D programs. The results showed that the H-type with only expanded shoulders and less design variation had a high similarity between the reference photo and real garment, the real and virtual garment, and the reference photo and virtual garment. The power shoulder jacket of the reference picture was well reproduced in the real and virtual garments. Conversely, the X-type jacket, which is a tight fit and has many design variations, showed somewhat low similarity in the circumference items and the basic construction line. Especially in tight-fitted power shoulder jackets, the fact that shoulder angles and the essential items for pattern making cannot be reflected in reproducing virtual models was found to be a limitation in increasing the similarity of virtual clothing. Furthermore, the sewing system gap between the real and the virtual clothing exposed a difference in the appearance of virtual clothing.

This study used data from a survey of adult Korean women in their twenties to learn their current practices for wearing and purchasing tight-fit jeans available on the market as well as perceptions regarding size measurements and satisfaction levels. We then determined product sizes and pattern measurements for the type of jeans worn. This study also analyzed discrepancies in product size measurements among brands to determine whether the measurements were generally suitable for average body shapes and measurements of women in their twenties. The study results were as follows. First, the survey asked women in their twenties about current practices in wearing jeans. Many respondents answered that their preferred fit is "a perfectly snug fit" and that the most common fit style of jeans was the skinny fit. Second, we selected a test pair of jeans with an identical fiber content from brands that women prefer to wear, according to the survey results. We researched the product measurements of the size respectively labeled 27 inches for each of the 8 brands' test jeans; consequently, the results showed that there were significant differences among the brands in the product measurements of each part of jeans. Third, we analyzed the pattern measurements of 8 selected brands for each area and identified pattern characteristics by brand.

In this paper, various structures of the healthcare smart clothing for real-time measurement of vital sign were suggested. The wearing efficiency was evaluated to find out the best ergonomic clothing in the suggested design. The supplementary effects of the clothing components (princess line, double fabric, cushion) on the stable and tight positioning of sensors to the body were evaluated with wear test. Five experimental clothing for male subject were made with closely-fitted shape and they included two representative structure: one was the integrated type of inner and outer garments and the other was the separated type with two garments. Eight subjects in their twenties were participated in the wear test to evaluate the wearing efficiency of experimental clothing. As results, the clothing structure of the separated garments with the inner and the outer shells were evaluated as more efficient and comfortable. However, the effects of clothing components on the light positioning of the sensors to the body surface were not differentiated each other in the subjective evaluation.

목적: 콘택트렌즈 피팅 시 렌즈 관련 사양의 변화에 따라 다른 값을 가지는 각막에서 산소부족이 없는 최소 Dk값 및 산소농도를 계산/확인할 수 있는 프로그램을 수립하고자 하였다. 방법: 엑셀 프로그램을 이용하여 콘택트렌즈착용 시 렌즈 아래 형성되는 눈물층의 두께와 Dk값을 계산할 수 있는 방정식을 세우고 수치 계산 모델을 확립하였다. 결과: 렌즈사양을 변화시키면 렌즈 아래 눈물층의 두께가 변하며 이에 따라 산소투과도가 다르게되므로 각막이 요구하는 최소 산소농도 역시 달라짐을 계산으로 확인하였으며, 눈물층의 두께를 위한 계산 프로그램은 눈물층의 형태에 따라 다르게 선택되어야 함을 밝혔다. 즉, flat 피팅 시에는 렌즈가장자리와 각막이 만나서 만들어지는 오목면의 형태에 따라 렌즈 아래 눈물층의 두께가 결정되며, flat하게 피팅 될수록 각막주변부 표면의 산소농도는 감소되어 계산값으로는 (-)가 되며 실제로는 산소농도는 0이 된다. Tight 피팅 시 각막표면의 산소를 계산하면 tight 피팅으로 눈물층의 두께가 렌즈의 두께보다 극단적으로 두꺼워지게 되어 계산값은 역시 (-)가 되며 각막 표면의 산소 농도는 0이 되어 산소결핍을 야기하게 됨을 알 수 있다. 결론: 콘택트렌즈의 변수를 조절하여 피팅 상태를 변경할 때에는 눈물층의 두께와 이에 따른 각막표면의 산소농도를 정확하게 계산하여 산소결핍이 나타나는 일이 없도록 하여야 한다.

When we develop 2D pattern from replica of human body with small pieces, it is inevitable to have some replica pieces overlapped or departed. In this study, the optimized method of 2D pattern development from the 3D replica pieces was investigated using dress-form. Among six arrangement methods, anchoring two vertexes of a replica to neighboring vertexes of a next replica induces the optimized 2D pattern by evenly distributing stress across the 3D replica pieces. Anchoring neighboring vertexes resulted in automatic widening k overlapping (W & O) the interspaces among replicas of dress-form, thereby stress was distributed more evenly than any other method. W&O arrangement method was verified to be the best by examining the 3D space distribution images between body surface and twelve experimental garments.

The objective of this study was to develop lightweight, stretchable, tight-fit smart sportswear using the conductive yarns into the garment and demonstrating its usefulness. Sportswears with the ability to control LEDs with respect to lighting of the surrounding were developed by applying embroidery with conductive yarns to 2 types of men's T-shirts and 2 types of women's leggings pants for outdoor activities and exercise purposes. LEDs were applied to the front and back of men's T-shirts and to the rear of the waist of women's leggings. Men's T-shirts were printed where the LEDs were to be applied, and inside, they were embroidered with conductive threads on the hot-melt fabric to be attached, and then connected with LED. Women's pants were embroidered on the elastic band, in the form of a sine wave that gives it ability to stretch, and finally the elastic band was hidden inside the waistband. The operation of the light sensor in the dark provided the ability to protect joggers from night drivers or cyclists. LEDs were activated when the wearer turns on the fashionable device on his/her shoulder by pressing it. It was able to reduce the risk of accidents by giving recognizability to vehicles, bicycles, and athletes approaching or passing by at night, and securing safe distance from vehicles, etc. Internal embroidery technology had the same flexible and lightweight functions as ordinary clothing products, making it possible to apply to tight-fit smart T-shirts or leggings pants designs.

This study aims to analyze the style of men's suits and extract expressional words for the development of semantic differential scales of visual images according to the change in silhouette. Research methods are literature studies, case studies, and questionnaires. The stimuli were created using CLO 3D, a virtual sewing CAD. This study's results are as follows: 1) The British suit jacket has an angled shoulder line using thin pads, and a slightly higher waistline. The pants of the suit have a high waistline and two pleats, so the thighs of the pants are wide. The American suit jacket has a natural shoulder line, and the waistline is not emphasized. The width of the jacket is relaxed, and the length is long. The pants of the suit have a higher waistline, and the pants are wide as well. The Italian suit jacket has wide shoulders, and the waistline is connected lower with a soft curve, and the length is relatively short. The trousers of the suit are tapered and get narrower as it goes down to the hem. 2) Because it originated in the practices of true bespoke tailoring, traditional British suits have a far more 'fitted' silhouette than the mass-produced styles that became emblematic of the American style. By the late 1950s, a sack-style suit was standard American business attire. This technique gives the sack suit its characteristically 'boxy' silhouette. The "Continental" presented a highly tailored silhouette, with padded shoulders, a slim, tight-fitting chest, and a closely tapered waist. The story was that Italian culture valued aesthetics over all else and thus sought the 'slim' suit style as much as possible. 3) The main expressional words of visual images for men's suits differ greatly depending on the silhouette of suit. The visual images are ranked in the order of 'neat', 'classic', 'educated', 'hard', 'mature', for fitted silhouettes. The words of 'masculine', 'basic', 'comfortable', 'simple', 'mature', 'conservative', 'modern', are ranked for boxy silhouettes. And the words of 'slim', 'young', 'neat', are noted for slim silhouettes.

The purpose of the present research was to analyse for a sample of female collge students by Korean and American the preferred style of clothing with body cathexis. The respondents were 242 Korean and 145 American female volunteers aged 18 to 27 who were enrolled at Kwangju and Cathlic University of korean and Cornell University in the Unites States. The questionnaire was composed of three sections: body size body cathexis and the preferred style of clothing. Sixteen items of twenty-six items of the preferred style of clothing showed a significant difference between Korean and American. Korean students didn't like a bulky fabric and a bright color than American do. American students like a effect of accessories and clothing to emphasize my bust line and care about sleeve shape skirt length skirt shape than Korean do. Korean students were more dissatisfied with their body than American female students. There was a negative relationship between body cathexis and preference of tight skirt both Korean and American female students. There was a positive relationship among body cathexis and preference of outfit and preference of garment of polished silhouette by Korean female students a positive relationship among preference of fitted waist and design to emphasize bust line.
