Various decorative patterns and sculptures found in antique architectures like palace architecture and temple architecture are not only valuable assets of our culture but have religious meaning at the same time and show aesthetic aspiration and desire of Korean people. In this study, potential application of patterns in textile industry is suggested based on the reconstructed and patternized geometric patterns of window grids, a decorative element in architecture, and stair and stair somaetdol, a architectural element in Buddhist temples, using Photoshop and Illustrator program of Adobe INC AND Tex-pro program of Youngwoo CNI INC. All around the world today, efforts to reinterpret unique and antique architectures and cultural assets in a modern way has been increasing. Decorative patterns displayed in Buddhist temple architectures which are antique Korean architectures have excellent geometric aesthetic value. And the development potential of patternizing these elements into modern designs is high. Therefore, it is thought to be possible to develop high value-added fabric and to develop various fashion items including apparel and interior decoration based on modern reinterpretation of patterns of window grid and decorative elements of stairs and stair somaetol that are part of our antique architectures.

As cultural diversity has gained a great deal of attention and the social fabric of Korean society is redefined, the number of studies on multi-cultural family homes has been growing in the area of human ecology, but relevant research is rarely found on the subject of housing. While the emphasis of housing research is on multidisciplinary approaches and empirical research is highly valued, a theoretical and methodological platform for discussing the new rising agenda of multi-cultural family homes is lacking. The purpose of this study was to explore approaches to and to discuss the issues in research for multi-cultural family homes in terms of housing theories and multidisciplinary approaches. To understand the housing related needs of multi-cultural families, this study highlights social constructionism, the ecological perspective, and feminist epistemology. These three multidisciplinary approaches were useful for generating an ontological analysis of multi-cultural family homes. Further, this study highlights two housing related theories, the microsociological and housing pathways approaches, for dealing with multi-cultural family homes. In conclusion, the five approaches were useful for exploring issues in housing research on multi-cultural family homes with appropriate research methods like hermeneutics, quantitative, and qualitative methods, and field research. Insights into using perspectives and holistic approaches might be useful for solving the problems of multi-cultural family homes in Korea.

A small diameter steel-ball impact experiment was performed to study the impact resistance of the surface of glass plates bonded with glass fabric/epoxy lamina. Five kinds of materials were used in this study: soda-lime glass plates, glass/epoxy lamina(one layer)-bonded and unbonded glass plates, glass/epoxy lamina(three layers)-bonded and unbonded glass plates. The range of impact velocity was 40 120m/s. The maximum stress and absorbed fracture energy were measured on the back surface of glass plates. With increasing impact velocity, various types of surface cracks such as ring, cone, radial and lateral cracks took place in the interior near the impacted site of glass plates. The cracks drastically decreased with glass/epoxy lamina coating. The surface fracture behavior could be evaluated using the maximum stress and the absorbed fracture energy.

This study examines the influence of control algorithms on dimming performance to determine appropriate control setting when direct/indirect lighting is controlled by a daylight dimming system. Computer simulation were performed for a small office with double skin envelope under various daylight conditions. A retractable fabric shading and Venetian blind were applied for internal and external envelopes under three CIE standard sky conditions. Unshielded and partially-shielded photosensors were used, and three control algorithms were applied for the sensors. In general, dimming level was too excessive due to the direct impact of light from lighting fixture to the photosensor. Providing insufficient lighting output, the unshielded photosensor completely failed to secure required illuminance under any daylight condition. When a partially-shielded photosensor was applied under clear sky, three setting points functioned effectively. Less sensitivity for the partially-shielded photosensor was effective to control the dimming system optimally with reasonable energy saving. However, the daylight dimming control system for direct/indirect lighting does not appear to be energy effective when photosensors without enough shielded area is installed on ceiling where light from fixtures reaches directly.

In this study, an innovative anchoring approach has been developed dealing with all relevant aspects in consideration of previous works. An ultimate pulling force calculation of anchor is presented from a geotechnical point of view. The proposed umbrella anchor focuses not only on the friction resistance capacity, but also on the axial capacity of the composite end structure and the friction capacity occurring around the wedge. Even though the theoretical background is proposed, in-situ application requires high-level mechanical design. Hence, the required parts have been carefully improved and are composed of anchor body, anchor cap, connection brackets, cutter vanes, open-close ring, support elements and grouting system. Besides, stretcher element made of aramid fabric, interior grouting system, guide tube and cable-locking apparatus are the unique parts of this design. The production and placement steps of real sized anchors are explained in detail. Experimental results of 52 pullout tests on the weak dry soils and 12 in-situ tests inside natural soil indicate that the proposed approach is conservative and its peak pullout value is directly limited by a maximum strength of anchored soil layer if other failure possibilities are eliminated. Umbrella anchor is an alternative to conventional anchor applications used in all types of soils. It not only provides time and workmanship benefits, but also a high level of economic gain and safe design.

A designed object reveals its meaning and image through form, color and material. Among these three elements, material has more powerful influence with its tactile and visual characteristics. In Korea, traditionally materials itself were mainly used to design artifacts rather than various color or formal decoration. The purpose of this study is to investigate the Korean traditional materials, and to classify them by the characteristics of their texture. For this study, the pictures of Korean traditional artifacts were collected from the national museums and literature. Those are architectural and interior elements, furniture, cloths and textiles, arts and crafts. Total of 533 collected artifacts were classified into seven categories, metal, day, stone, paper, wood, straw, fabric things. : 59 metal things, 115 clay things, 62 stone things, 73 paper things, 80 wood things, 47 straw things, 97 fabric things. Each materials were classified into its forming methods and surface treatment focused on the he characteristics of their surface texture. Throughout this study, the uniqueness of forming method and surface treatment of each materials in Korea has been clarified. And furthermore the classification by this various traditional methods of materials will provide plentiful information and ideas to today's designers of the world.

In the textile industry located in Gyeonggi-do, 85% of small-sized firms have less than 10 employees; in addition, the most of them are characterized by a vendor relying specialization system that conducts foundry from the vendor that managed marketing, textile design development, and quality checks according to unit stream. The breakaway of these vendors accelerated over the last 7 years; however, industry survival is at stake because the specialization system and orders have collapsed. The following four main policies must be implemented to overcome industry hardship. Policies have been derived from survey and analysis (present condition and trends) from industrial statistics and related policies in advanced and developing countries. First, a policy to promote cooperation between small-sized foundry unit-streams. Second, unification of the marketing support function with a textile design and development support system. Third, the introduction of policy support-management system customized according to developmental stages (tall process${\rightarrow}$fabric production${\rightarrow}$sales${\rightarrow}$clothing production sales). Fourth, foundation of a control tower that puts these tasks in a vehicle and runs them and the division of roles with the central government. We must propel main tasks to manifest the developmental potential (develop eco-friend dyeing and processing technologies, change to the young next CEO in business environment, and grow the of knit market) of the Gyeonggi Textile Industry in a short period to present a condition where these four main policies are running.

This study aims to analyze functions and characteristics of 'Cha-il(遮日)' which was used at ritual events(宮中儀禮行事) in the Joseon dynasty, Joseon dynasty had many ritual events related with O-Rae(五禮). Cha-il was almost used at important ritual events, especially at the congratulatory events. The congratulatory events(宮中宴享) are the representative events were held with many temporary install facilities(假設施設) in a palace. Cha-il was a kind of Korean traditional membrane structures. Cha-il was set up for cutting off interior space from sunlight and rain. In general, Cha-il was Consisted of Cha-il-jang(遮日帳:woven fabric), Cha-il-jook(遮日竹:bamboo column), some ropes, and fixing wares. In the congratulatory events, three types of Cha-il. were set up. Baek-mok-Dae-Cha-il(白木大遮日)was made of cotton cloth. Yu-Dun-Cha-Il(油芚遮日) was made of oiled paper or oiled cotton cloth. Man-Joen-Cha-Il(滿箭遮日) consisted of wooden structure. Baek-mok-Dae-Cha-il(白木大遮日)was set up on the most important area of stage for protecting from sunlight. Yu-Dun-Cha-Il was set up on less important area of stage for protecting from sunlight and rain. Man-Joen-Cha-Il was set up below Baek-mok-Dae-Cha-il for supporting and draining raindrops off. The results of this study were as follows; Functions of Cha-il were to protect ritually space from sunlight and rain, and to extend ritually space, and to reconstruct ritually space. Cha-il was the peculiar temporary install facility which differed from other countries.

The purpose of this study is to examine the characteristics of modular design observed in Korean traditional clothing. Modular design, which is one of the noticeable characteristics of modern fashion design emerged in the 20th century. This study analyzed the Korean traditional culture to investigate the characteristics that show similarities to the modular system in design. A traditional Korean house is composed of small structures called 'chae'. A traditional Korean building is composed of a basic unit space called 'kan', and the rooms are divided and recombined. Korean traditional interior design shows furniture, bedding and art works that could be used, folded then stored. Korean cuisine is served in combination with small dishes. Korean letters are combined in square shaped form to make writing and printing easy. Korean traditional clothing has a way of washing where clothing are disassembled, washed and then re-stitched. The pattern pieces are made to be rectangular shaped so that the fabric pieces can be kept in shape during washing. The rectangular shaped pattern pieces can be replaced and reused after washing. Tops and bottoms could be interchanged for color-coordination, because the shapes of the clothing were standardized. These features exhibit modular system in Korean traditional clothing design. Modular system design has common characteristics which have basic modules, pursue practical purpose, have interchangeability adapted to circumstances, and could be disassembled and re-combined. Korean traditional clothing illustrates different ways of practicing modular system, but has some common features to contemporary modular fashion design.

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.
