The purpose of this study is to analyze the technical pattern and product characteristics of outdoor sportswear marketed in Northern Europe and North America. Based on the results of this study, we wanted to provide practical data on the characteristics of products with high functionality and fashionability for developing outdoor sportswear. Therefore, in this study, technical pattern, textiles, details, sewing, compatibility with wearable devices, and certification of 33 marketed outdoor sportswear were analyzed. After analyzing various technical patterns, the bent arm pattern using two-piece panel and a raised arm pattern connecting the side seam with the inner seam of the sleeve appeared on the top. Additionally, the patterns of bent legs with darts in the knee, cutting the posterior, and inserting the gusset in the crotch were mainly seen in the bottoms. By analyzing product characteristics, ergonomic pattern design for easy activity and functional materials was used for climate adaptation in extreme outdoor wear. On the other hand, for outdoor wear meant for trekking or hiking, details, such as portability and easy storage, were considered. Eco-friendly materials were used while ensuring light weight and comfort. Furthermore, for convenience of life, safety, and health, wearable devices were integrated into the outdoor sportswear. Eco-friendly green certification of outdoor products was obtained for the labor environment and production process, and relevant information was provided to consumers.

The Christianity that spread to Egypt in 3rd century in A.D. is called Copt. Coptic Church built a lot of monasteries along the lower stream of Nile River, which produced thousands of text and paintings. Ethiopia is well known for its worship to Virgin Saint Mary and produced many paintings of Virgin Saint Mary in different costumes. The pictures usually came in foldable small books containing 3 pictures. The paintings usually featured Virgin Saint Mary and Jesus Christ dressed as royalty in crowns, saints and angels. There are saints on white horse, mirroring the oriental influence on Coptic painting. This research will look into the patterns and colours on the Coptic textiles, mainly tapestry.

Polypropylene(PP) is a textile material with various functions such as eco-friendliness, lightness, and elasticity. Although most synthetic fibers can be dyed and finished, but original PP is difficult to dye or finish due to its extremely hydrophobic properties, so its application expansion is limited. In order to solve this problem, dyeable PP was developed, and various researches on textiles for clothing such as mass production technology, fine fiberization and performance improvement are in progress. Plasma treatment is a processing method for modifying the surface of fabrics, and has effects such as hydrophilization, deepening color, improving adhesion, and surface polymerization. In this study, plasma treatment was applied to study changes in hydrophilization properties of dyeable PP, surface changes before and after plasma treatment and performance according to hydrophilization.

The purpose of this study was to research the design methods to express jacquard design using CAD. For this study, two design patterns were divided; in addition, each design pattern is applied to two different weaving types, single woven fabric and double well cloths. As a result, 16 samples were produced by applying 4 design methods (warp shrunk as half size design/weft shrunk as half size design - A, warp shrunk as half size design/weft original size design - B, warp original size design/weft shrunk as half size design - C, warp original size design/weft original size design - D) to the two design patterns with the two weaving types. The result of this study can be summarized as follows. 1. The most delicate design method was Method D. However, Method B which took half the time less than Method D was almost as delicate as the Method D on the surface. 2. Method B was judged as a considerably efficient method for time and cost. 3. Method D was considered as most suitable for elaborate parts and delicate lines. However, it was considered uneconomical since it took the longest time. 4. Mettled A took 2.5 times less time than Method D. Therefore, Method A was more applicable to producing high density design. 5. Method C is not considered as a useful method as it showed rough surface and took long time by applying high design zoom except intentional design.

Two hundreds of female aged 19 years old and up were recruited to evaluate the postural changes and bilateral variation of asymmetry over age. To find out the differences among the age group, subjects were classified into 5 groups, early young age(19-29), late young age(30-39), early middle age(40-49), late middle age(50-59), and old age(60-). 35 body measurements were taken by the 3-D body scanner which allowed us to take measurements which cannot be measured using traditional methods, including the shape of a cross section, slice area surface are, and volume. Bilateral variations were observed as a function of age; Depth of scapular point level, scapular point to center back, and blade angle. Postural change of anterior cervical angle, upper anterior thoracic angle, upper posterior thoracic angle, posterior cervical angle, and center back/center front ratio were also exhibited. In each measurements, subjects were classified into normal, and abnormal group. Percentiles of abnormal in shoulder line angle, blade angle, neck point $\∼$ acromial point $\∼$ scapular point, posterior cervical angle, and upper posterior thoracic angle were increased over age group. The upper body of lateral view was classified into 3 types of posture based on the previous research; straight, erect(leaning back), and stooped(bent forward). The percentiles of subjects who have straight postures were decreased as a function of age, but those of stooped postures were increased. Subjects who have erect postures did not so. The stooped posture group shows the big cervical fossa angle, anterior cervical angle, posterior cervical angle, upper posterior thoracic angle, and the small upper anterior thoracic angle comparing to the straight and erect posture group. These results could be apply for clothing construction reflecting the changes in back, shoulder, neck, and the bilateral asymmetry according to the target age group.

This study attempts to adapt and develop Korean prehistoric petroglyphs into textile design for children. For this purpose, literature review was conducted to understand the plasticity and symbolism expressed in Korean prehistoric petroglyphs. Also this study conducted textile design development as follows: First, the figures and faces in petroglyphs were selected because children can easily recognize them. Second, two groups of different ages (7-9 and 10-13) were allowed to freely draw the selected motifs. Third, some of the motifs created by the children were selected that show children's individuality and also keep the features of the original motifs. The children's motifs were developed into textile design using Texpro and Photoshop. Then digital textile printing and 3D mapping program were used to make pajamas (5 types), umbrellas (3 types), and simulate bedding sets (2 types) for children. This research's results are as follows: First, petroglyphs are symbolic language of human's oldest art form, and related to religious and mythical belief. Korean petroglyphs have plasticity showing the development steps in technique and expression, with various shapes such as animals, human figures, faces, masks and abstract figures. Third, children showed their interests in various human figures and faces of the petroglyphs, and it was easy to draw those motifs in their own way. Fourth, 10 design motifs were selected from the children's work and used to create textiles considering materials and colors for children. Total 10 items were made and presented. This study confirmed the usefulness of applying prehistoric petroglyphs to children's textiles designs. These designs may grow as a kind of cultural product for children who know about and like petroglyphs. They can be a niche market items too, made to order for children with individuality and who favor originality.

The purpose of this study is to verify the change of body posture by putting on the late $19^{th}$ century English women's bodice or waistcoat. This study analyzed the female somatotype which puts on upper garments of Victorian era with using 3D body scan technology. Two sets of $19^{th}$ century women's bodice and waistcoat patterns were developed with the $19^{th}$ century model size and those patterns were used for making the experimental garments. The fit of experimental garments was evaluated by the degree of change with posture and waist measurements. Three women with the same waist girth measurements with the model size were participated to the fitting test. The postural change was measured from cross-sectional body diagrams. The result of this study showed that the waist measurement of the late $19^{th}$ century English women's bodice and waistcoat pattern was smaller than the waist girth measurement. These garments compressed the midriff of the body and it made women's distinct body silhouette. The waist girth measurement of 1876 bodice pattern was 9.2cm smaller than presented model size. The subjects' waist girth measurements were shortened by 5.0~6.1cm after wearing the 1876 bodice garment. The waist girth measurement of 1880 waistcoat pattern was 7.1cm smaller than presented model size. The subjects' waist girth measurements were shortened by 2.7~3.7cm after wearing the 1880 waistcoat garment. The back side parts of their waist were compressed and their postures were changed. The neck and shoulders were moved forward after wearing the experimental garments. These results showed that body posture could be changed to "S" shape silhouette as wearing the late $19^{th}$ century English women's bodice or waistcoat.

The purpose of this study was to study accumlated residual soils which may be one of the causes for yellowing of worn cloths. Wear and wash tests of white cotton undershirts were repeated at 30 households sellected at random over a period of 60 days. Laundry conditions were similar to home laundry habits in a fact-finding survey, using a powdery heavy duty detergent containing no enzymes or enzymes. The subjects in this study were survey of laundry actual condition, the undershirts from prior to and after the final washing was measured residual soils, $L^*a^*b^*$ value and mellowness index of CIE system. D3ta were analysed by simple correlation analysis of wear and wash cycle, residual soils, whiteness The results obtained were summarized as follows: 1. Using pattern of washing machine, Presoaking was no singinificant differnece in general characteristics of survey respondent. Laundry frequency was significant difference in income level, occupation of housewives whether or not. Use of cold and hot water was significant difference in residence shape. 2. The analyzed consequences of recognition and actual behavior in connection with laundry were found variables each other to have independence or not. 3. Amount of residual sebum soils is using non-enzyme detergent were much more than in using enzyme detergent, increased linearly with increase of the number of wear and wash cycles. 4. Residual protein soils with increase of the number wear and wash cycles less than in laundering more easy than sebum soils. Since accumulated residual sebum soils were much more than residual protein soils. 5. Increase of residual soils was raised mellowness index and diminshed whiteness. yellowness index of residual sebum soils was higher than protein soils. If increase of whiteness will be incresed, amount of residual sebum soils will be decreased sebum soils. Because amount of residual sebum soils much more than protein soils, yellowness index of residual sebum soils was more higher than that of protein soils.
