Hangeul is growing as cultural icon representing Korea. And Hangeul is scientific and is too systematics for words as the guide of modern design. First it can make the variable and beautiful foams like dot, line and plane. It also has the basic design principles like symmetry and repetition. The purpose of this study is to develop textile designs using the formative characteristics of Hangeul. So in this study it was chosen 'ㄱ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅍ' of Hangeul's consonants and 'ㅑ, ㅕ' of Hangeul's vowels as the subject materials of textile designs development to develop textile designs expressed the geometrical shapes and formative beauty of Hangeul. Those are designed by using a variety of motifs that recast the shapes of Hangeul. So six textile designs for necktie and scarf were developed. Through this study it will be offered to the possibility of products that was based on Hangeul.

This paper introduces scarf welding process of thin substrates using flexible laser transmission welding (f-LTW) technology. We examined the behavior of tensile strength relative to the scarf angle for flexible applications. Thin plastic substrates with the thickness of less than 100 ㎛ were bonded and a jig to form a slope at the edge of the substrate was developed. By developing the scarf welding process, we successfully created a flexible bonding technology that maintains joint's thickness after the process. The tensile strength of the joint was assessed through uniaxial test, and we found that the tensile strength increases as the slope of bonding interface decreases. By conducting stress analysis at the bonding interface with respect to the slope angle, design factor of bonding structure was investigated. These findings suggest that the tensile strength depends on the geometry of the joint, even under the same process conditions, and highlights the significance of considering the geometry of the joint in welding processes.

This paper aimed to find out the eco-friendly approach enabling to directly print patterns and dye colors on fabrics using leaves of plants. In the research process, I found out the 'eco-printing' which could effectively express unique colors and patterns of plants. While eco-printing can design the patterns and colors of plants in nature using the leaves of plant(Eucalyptus), it is difficult to implement because it is not systematically and academically investigated including the dictionary definition in Korea until now. Thus, I tried to define the eco-printing and natural dyeing using leaves or flowers of plants enabling to get natural patterns and colors and do the experimental research and production using the leaves of Eucalyptus. The leaves of Eucalyptus were arranged on a wool scarf and a silk scarf, tied and applied pressure to them and made pigments penetrate into fabrics by heating or steaming them. This approach is to directly print the patterns using the shapes of plants on fabrics unlike the existing approaches dyeing by extracting dyeing solution from natural materials. Furthermore, the change of colors was attempted by using the color fixers. In accordance with the results of this experimental research, the scarf design differentiated from the existing products could be acquired. It was identified that eco-printing could induce the color variables depending on the conditions of each material and environment. For improving the color variables, various kinds of fabrics and divers kinds of materials which can be easily acquired in a daily life will be investigated and compared. Furthermore, it is expected that the experimental research and production techniques on eco-printing be utilized when starting natural dyeing and the scope of natural dyeing be more expanded.

This study developed a practical knitwear design with applying the pattern of Queen Yeong's pearl pouch. The ume flower pattern of pearl pouch was simplified to be one repeat pattern, and four simulated knit pattern samples of G-A, G-B, R-A, and R-Bwere made with cable, cross, and two background colors of gray and red using Texpro V.11.0. The items of design application were selected after an interview with a panel of university students in their twenties and knit samples were produced by hand knitting. The small sized G-A for the partial ornament of hat, sweater, skirt, kitchenware case and accessories; the long sized G-B for the tuck of sleeves, hem of skirt and one-piece dress, partial ornament of sweater, scarf, and curtain decoration: the small sized R-A was preferred for point ornament of pouch, boots, hat, partial ornament of children's fashion products and accessories: the long sized R-B for table runner, leg warmer, tuck of sleeves, skirt hem, necktie, and scarf. The knit samples were formulated with partial ornaments attached on dress and props or connected each other. Colors of pastel and navy were also presented to meet the demands of panels. The study placed a limit on the slight difference between the simulation samples and knit samples due to the characteristics of threads and hand tension. The color variation for multiple coordination and activation to reduce the piece rate for young customers remains to be discussed in the near future.

Bicycle riders complain of many inconveniences when wearing glasses, sunglasses and masks. The disposable fine dust mask has been developed to resolve such inconveniences of bicycle riders. The scope of research is limited to the fiber which generates one-time static electricity and the shape of the mask due to the characteristic of fine dust mask. The purpose is to design and make the fine dust mask with a simple production process. The new disposable fine dust mask has secured enough space of the mask in front of the mouth by longitudinal folding and minimized stuffiness by maintaining the shape of the folded part to prevent touching the mouth even by heavy breathing. The streamlined sponge is attached at the part of nose support and the area of the cheek has been expanded to be about 2.5cm wider than ordinary masks to improve tight seal at the side. In addition, a new disposable fine dust scarf mask has been developed to block ultraviolet rays for the face and neck while filtering fine dust with the tight fine dust mask.

This study reinterpreted the formative design elements of traditional grate patterns to create new lattice patterns and come up with a design concept for fashion-cultural products that highlight the uniqueness of traditional Korean culture and its characteristic features. Methodologically, the computer design software programs Adobe Illustrator CS2 and Adobe Photoshop were used to make grate patterns motifs. and they were applied to scarves and again to blouses using a three-dimensional simulation technique. In this study, three basic motifs for a new formative image were set using graphical functions such as omitting, simplifying, overlapping, repeating and reducing shapes based on the images of traditional 亞-shaped, arched and floral lattices, and each motif was expanded to have two variations with different colors applied to them. The direction of basic motif design was set to fit for each of fashion-cultural items such as scarves and blouses. Basic colors for motifs were arranged to create a colorful and modern but staid image in pink, blue, purple, green, yellow and brown tones. Based on a developed motif, changes were made in blouse design with lattice patterns through a variety of effects such as repetition, rotation, cross-arrangement, and oblique arrangement, and three-dimensional simulation was used to bring the design to life. Scarf design employed and applied the existing motifs in an appropriate manner for design purposes and reconstructed them through such effects as repetition, rotation, compositional variation and gradation to express a gorgeous and refined image.

Each season, many clothing companies dump small pieces of fabrics left over from making samples. Since fabrics do not decompose easily, this results in environmental pollution. This research was done to discover effective ways to reuse these fabric remnants. As most of these remnants were not large enough for making clothes, fashion accessories was chosen as the design object. Four steps of design development process followed: information research & analysis, prototype design & sample making, market testing, final design decision. After market research and trend analysis, four neck decoration wear -- scarf & muffler(SM). collar & cape(CC), vest & top(VT), and necklace(NE) -- were selected as final product types. 45 designs arose, and 120 items with variations in fabric materials and colors were produced as samples. The three main themes (multiple. reversible, cross) were applied throughout all of the design items. Samples were evaluated from the reactions of the consumers through a 10-day sale at a retail store. Based on the sales record and customers' opinions, five designs from each of the product types SM, CC, and VT were picked out as final designs. In conclusion, fashion accessories turned out to be a more appropriate item to reuse fabric remnants from clothing companies than clothes were, because they necessitate small fabric size and the limitation in fabrics could be compensated with creative design ideas.

This study attempted to understand the value of traditional floral wall patterns reflecting the distinct aesthetic consciousness of Korean people and reinterpret the images of floral wall patterns in simplified forms. In addition, the study created new floral patterns to apply them to the design of neckties and scarves. In a methodological aspect, the computer design software programs Adobe Illustrator CS2 and Adobe Photoshop CS2 were used to make the traditional floral wall patterns motifs. Four basic motifs for a new formative image were set using graphical functions such as omitting, simplifying, overlapping, repeating, and/or reducing shapes based on floral wall patterns, and each motif was developed in two variations with different colors applied to them. Each of the set motifs was expressed in a repeated arrangement and in a modified pattern of 45 degrees. Necktie design with a floral wall pattern made use of the motifs developed through a variety of effects such as simplification, repetition, size variation, and gradation and the pattern modified at a $45^{\circ}$ for application. Scarf design employed and applied the existing motifs in an appropriate manner for design purposes and reconstructed and expressed them through such effects as repetition, rotation, compositional variation and gradation.
