The study investigated the effects of SNS usage on 20s and 30s female SNS users' internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders based on objectification theory and social comparison theory. The study examined differences on SNS usage and body image variables between high and low groups of SNS envy and self-compassion. Social Network Service (SNS) is used as a contemporary marketing tool for brands and companies. It also influences the body image of female SNS users. The survey used an online survey company for female SNS users in their 20s and 30s to analyze the effect of SNS usage. The results showed that SNS usage significantly impacted the internalization of a thin body, body surveillance and appearance upper comparison. The internalization of thin body also had a significant impact on body surveillance and appearance upper comparison. Appearance upper comparison positively affected body dissatisfaction and eating disorders. Finally, the group with higher SNS envy showed higher SNS usage, internalization of thin body, body surveillance, appearance upper comparison, body dissatisfaction and eating disorders. The group with higher self-compassion showed opposite results. This study provided a theoretical expansion for a SNS and female body image study with objectification theory and social comparison theory. It also suggests positive SNS marketing strategies use for brands. Lastly, this study emphasized the importance of the proper use of SNS to protect the body image of SNS users.

This study provided data for classifying and characterizing the lower half of the body shape for obese adult men in their 30s and 40s. Data of 492 adult males who were obese with a WHO criteria of >25 BMI were used for analysis. The results of the study are as follows. Six factors extracted from the factorial analysis as independent factors for cluster analysis were classified into three types. Type 1 (65.4%) had the lowest height of the lower half of the body with short circumference and length. Type 2 (20.3%) had the lowest height of the lower half of the body with the largest thickness, width and circumference from the back to the hip, but short in length. Type 3 (14.2%) had the lowest height of the lower half of the body with medium height and waist-height; however, the curve from the waist to the hip was the largest with the largest waist circumference, hip circumference, and width and thickness of the lower half of the body. This study will help to design a slack pattern that utilizes body shape characteristics of men in their 30s and 40s. In a follow-up study, we analyze the slack pattern and educational pattern by the company and study the necessity for a slack pattern for obese males.

The purpose of this study was to investigate the wearing & fit of ready-made and online custom dress shirts by surveying middle-aged men aged 40-54 years in order to collect information necessary for making good fit dress shirts. Also, we analyzed whether there were significant differences in the actual wearing of dress shirts according to the stature of middle-aged men. The stature was classified according to KS K 0050 as $R(157{\leq}x<170)$ and $T(170{\leq}x<182)$. The 23 questionnaire items were divided into three categories: 'General purchasing behavior and wearing', 'Fit satisfaction of ready-made dress shirts' and 'Wearing and fit satisfaction of online custom dress shirts'. Through the results of the study, we could understand the actual wearing condition of ready-made and online custom dress shirts. Also, differences in stature groups were found. The significant differences according to the stature groups were found in the interest in fashion, the purchase criteria, the limitation of the shirt size selection due to stature and body shape, shirt size satisfaction, repair experience, dissatisfaction with purchase and the experience of purchasing online custom dress shirts. Suggestions should be made to improve dissatisfaction with stature groups in the ready-made dress shirts. In addition, the study confirmed the consumer demand for the online custom dress shirts. In order to activate the online custom market, the online custom dress shirts company needs to reduce consumer dissatisfaction and improve size suitability.

This study develops 1/2 dress forms for draping. This study investigated the production status of domestic and foreign products in order to model their shape using CLO 3D. In addition, it developed torso-type and torso-crotch-type products that allowed for draping using a 3D printer. This study analyzed shape and size compared to developed ones after referring to the Size Korea 7th Survey data as well as seven domestic and foreign company websites. The results are follows. First, an investigation of the production status of the products for the size of most of the domestic ones (except K-4) indicated that the waist circumference was slimmer than Size Korea. Bust, waist, and hip circumferences ranged from 42.0 cm, 32.0 cm, and 45.0 cm - 49.0 cm, respectively, in Chinese products; 42.0 cm - 43.0 cm, 30.5 cm - 31.5 cm, and 46.0 cm - 46.5 cm in Japanese products; 43.0 cm, 35.0cm, and 46.5 cm in American products (Japanese body shape applied). Second, an avatar was produced on a 3D software with the average size of 20-24year-old women, and its file modified as a dress form for 3D printing with PLA filament to produce dress forms for draping, workable with pins, using quilting cotton and cotton cloth. Third, the comparisons of the form and flattening between the developed dress forms and the selling ones indicated that flattening was bigger in the waist part of the former than the latter. The waist is produced too slim in the existing dress forms; therefore, it is necessary to correct the waist circumference. Unlike existing dress forms, the developed ones were produced in proximity to the average size of 20-24 year-old women in the Size Korea 7th Survey.

To enhance the design and comfort of waist-protection corsets, this study analyzed the product characteristics of five types of posture-correction corsets that are available commercially. Additionally, subjective evaluation of the corsets was conducted on women aged 20 to 60 years, in terms of design, material preference, fit, comfort, degree of correction, freedom of movement, tightness, and convenience of front fastening. Following product analysis, the five corset types were divided into: two soft, one semi-hard, and two hard types in terms of the degree of elongation. As a result of pattern analysis, the soft type was designed to improve fit by reflecting the body curvature, whereas the semi-hard and hard types were relatively flat. Through the wearing sensation assessment, the hard type manufactured by company S was the best in terms of design, material, fit, comfort, correction degree, and freedom of movement. The soft type was average in design, material, and fit while relatively poor in the correction degree and tightness. The results indicated that soft materials, flexible bones with appropriate tension, patterns designed to snugly fit the body with large curvature at the top and bottom for better inflection, and adjustable support belts that can be double-fixed are crucial elements in improving the corset design to boost the comfort of wearing. These study results are helpful in the development of waist-protection corsets with excellent wearing comfort and design appreciated by customers.

Recently, the automobile industry is developing as the demand for automo- biles increases due to industrial development and population growth. In addition, many studies are being conducted to reduce heat loss inside the automobiles in order to save energy inside the automobiles due to environmental regulations. In this study, alumina, nanosilicon, and aerogel, which are adiabatic materials, were filled in PET to manufacture yarn, identify physical and mechanical properties, and weave into fabric to confirm adiabatic performance. As the content of the adiabatic material increased, the tensile strength of the fibers filled with alumina and nanosilicon decreased greatly, and the adiabatic property slightly increased. The tensile strength of fibers filled with the aerogel decreased slightly, but the adiabatic properties were greatly increased. Therefore, it is considered to be due to the large volume fraction in the PET yarn due to the low density of the aerogel.

국내 염색가공업에 종사하는 중소기업은 약 1,700여개 업체로써, 평균 50억/년 매출을 하고 있으며, 생산의 대부분을 임가공에만 의존하고 있는 실정이다. 이들 염색가공업체들은 섬유제품의 품질 향상 등을 위해 전처리, 염색, 가공이라는 섬유습식공정을 행하게 되는데 그 공정이 따로 분리되어 있어 임가공 업체 입장에서는 시간과 비용 차원에서 비효율적인 면이 존재하여 왔다. 따라서 공정합리화, 원가합리화를 위해 따로 분리되어 있는 위 공정을 통합하려는 시도를 많이 했지만 전처리/염색 공정의 통합에서 일부 성과가 있었을 뿐 효과면에서는 아직 미흡한 실정이다. 또한 가공이란 공정은 그사용 약제의 특수성에 따라 기존 Padding-Drying-Curing이라는 3 step process를 반드시 필요로 하고 있기 때문에 가공 공정의 통합은 시도조차 이루어지지 않고 있는 것이 현실이다. 따라서 염색공정과 가공공정의 통합을 시도하기 위해서는 관련 약제 개발이 출발이라 할 수 있으며 그 첫 대상은 염색 공정의 소핑과 가공공정의 유연처리를 동시에 행할 수 있는 소핑유연제로 선정하려 한다. 즉 셀룰로오스계 섬유의 반응성 염색 후 소핑 공정에서 일액형 소핑유연제, 한가지 제품만을 간편하게 사용해도 소핑효과와 유연효과를 동시에 얻어 후속 유연처리 공정을 생략할 수 있는 것이다. 그렇게 되면 시간적으로나 비용적으로 큰 절감 효과를 가져와 임가공 업체의 부담을 덜어 줄 수 있을 뿐만 아니라 공정 통합을 통해 배출되는 폐수의 양도 상당량 감소시킬 수 있을 것으로 기대된다. 본 연구 결과, 폴리옥시에틸렌 트리데실 에테르 타입의 계면활성제와 개질된 디메틸폴리실록산 계열의 실리콘 오일, 그리고 이들의 상용성을 확보하기 위한 특수 용제 및 첨가제를 최적의 비율로 배합하여 안정한 일액형 복합 소핑유연제를 제조할 수 있었다. 제조된 소핑유연제는 유백색 반투명 액상의 외관을 가지며 pH(10%solution)는 $7{\pm}1$, 고형분은 $13.5{\pm}0.5%$이었다. 이 소핑유연제의 성능 평가결과, 소핑력은 기존의 소핑제와 동등 수준으로 세탁견뢰도 4급이상의 성능을 보였고, 유연성 면에서도 기존의 유연제와 동등 수준으로 평가되었다. 이로써 기존의 분리된 소핑 공정과 유연공정을 개발된 제품을 이용하여 통합할 수 있어 염색현장의 비용절감, 공정단축의 효과를 기대할 수 있게 되었다.
