The purpose of this study is to verify how similar the virtual fit pants are to the actual fit of stretchable pants. Data is produced using a virtual model to apply movements. The results show that in the upright position, the similarity between the appearance of the actual fit and the virtual fit is high. Results are 4.47, 4.13 and 4.33 out of 5 on the front, side, and back, respectively. The base line of the front and back, and the amount of allowance in each part were well reproduced by the model. The texture of the virtual fit was evaluated and found to be similar to the actual fabric. In terms of shape and number of wrinkles with the virtual fit pants, large wrinkles were better expressed than fine wrinkles. After applying movements to the virtual model, the front and side results were similar to the actual fit, but the back results were different. As a result of multiple comparisons, the greatest difference in similarity by movements is found in the center front line. The similarity difference was lower on the side than on the front. The only significant difference after applying movements is in the hip circumference margin. According to movements, the similarity of virtual fit is lower on the back than on the front and side, and the back also has the largest similarity differences to the movements type.

전승되었거나 출토된 직물은 자외 가시광선, 산소, 미생물 등에 의해 열화 되고 변 퇴색되어 본래 색을 추정하기 어렵다. 색의 분리 분석에서 LC-MS 분석은 매우 효과적이나 염료 정성분석에 있어서 직물로부터 색소를 추출하는 과정이 특히 중요하다. 홍화와 락충으로 염색된 직물로부터 염화수소, 피리딘, 옥살산을 주 용매로 한 세 가지 추출방법 중 옥살산을 기반으로 한 방법이 적색소 추출에 가장 효과적이었다. 한편 열화에 따른 색소의 화학적 특성 분석을 위해 홍화와 락충으로 각각 염색한 시편을 자외선A로 168시간 열화 시킨 후 LC-MS로 분석하였다. 그 결과 홍화 색소는 $T_R$ 13 min에서 carthamin이, 락 색소는 $T_R$ 10 min에서 laccaic acid A가 검출되었다. 또한 자외선 열화 된 홍화 염직물의 MS분석 결과 주 색소인 carthamin은 검출되지 않았지만, 분자량 m/z 931의 물질을 통하여 홍화 염직물임을 확인할 수 있었다. 본 연구를 통하여 적색 염직물로부터 적색염료 추출을 위한 최적의 방법을 확인할 수 있었으며, 향후 적색염료의 정성분석에서 LC-MS분석을 이용한 기초자료로 활용될 것으로 기대한다.

In the Korean literature, records of systematic gold thread manufacturing such as gold foil(金 箔匠), gold foil bonded with fabrics(付金匠), gold foil bonded with paper materials(金箋紙匠), refining gold(鍊金匠), cutting gold(裁金匠), and making gold thread(絲金匠) can be easily found. We can infer from these literatures that the Korean people used to make gold threads. However, is not existent the gold thread making technique. Thus, a research was done using 67 pieces of gold thread artifacts used in textiles craft of Korea, China and Japan. The purpose of this research was to identify the characteristics of the Korean gold thread by studying the artifacts' form classification, gold foil, glue and the base. First, gold thread is divided into flat gold thread and wrapped gold thread. Wrapped gold thread was made in more various methods such as with a paper on the flat gold thread, metal thread and wrapped gold thread with gold foil on top. Compared to the flat gold thread, wrapped gold thread uses a thread that has a thinner and wider. Through this analysis, even making of the base of the gold threads was different according to the type. Secondly, we looked into the characteristics of materials according to form structure of the gold thread. After analysis of experiment results, we could know that to attach Korean gold thread, glue and the mixture of materials such as Red soil(朱土) was also added. The kinds of the base of gold threads were identified as paper, leather and intestines. Among those materials, for paper, Korea's Dakji, China's Sangpiji(桑皮紙) and Jukji(竹紙) and Japan's Anpiji(雁皮紙) seemed to have all been used, so because of the difference among countries, we can prove that Korea has also produced gold thread. By looking at the research, the base of gold threads and making features hugely vary according to the area.

Nowadays the issue of environmental pollution and ecological destruction is not a simple issue but an important issue to be continuously considered. It is deemed that a study for recycled new materials is immediately required and this study is to analyze features and processing methods of new materials which can be used to interior space. We found the recycled new materials used for space through researching various web sits. And then we analyzed what the base materials are and classified that base materials are whether natural or artificial of the recycled materials. We classified processing methods of the recycled new materials after researching general processing methods. The result of this study would be an important material to the research and development of new finishing materials with consideration of environment and to the research for a guideline of applicable new materials. The results of this study are as follows : First, we could classify widely 2 categories into natural material and artificial material and then 10 subcategories into metal, glass, wood, rubber, stone, plastic, leather or fabric, ceramic, concrete and so on, and analyzed that which material is mostly used and whether it is single material or multiple material. In order to analyze the feature of processing method. Second, we could classify into 4 categories such as junction, surface process, molding, and insert, and found out which processing method is applied based on objects of research. Third, as an analysis result of the recycled new material feature, in order to develop various new materials, it is required to study on combination and application of 2 materials or more rather than single material. Four, as a analysis result of the processing method feature, I would like to suggest that development and application of various processing methods are required. Especially, it is necessary to grope for a way to develop new functional materials for interior space through a systemic research and analysis of processing method of other fields. Furthermore, a way to reuse recycled new materials should be considered in a stage of selection and application of processing method.

The aim of this study is to find out comfortable combinations of layered system for outdoor activities through water vapor permeability. Layering fabrics is an effective way of controlling water transport properties in fabric systems for outdoor activities and analysis of these systems may be useful for designing comfortable clothing. Seven fabrics were chosen for the experiments: two fabrics for base layer, two for the middle layer and three for the shell layer. A total of 12 different layered systems, which are all possible combinations were established using selected fabrics. The water vapor permeability was measured using JIS L1099 under isothermal and non-isothermal conditions. It was found that layered system was working together as a whole having influence on each layer, though every layer offers varying degree of water vapor permeability. Furthermore, it was also found that an optimal combination of the three layered system does exist although the combination may differ according to the ways. The shell layer is the greatest effect of water vapor permeability under isothermal and non-isothermal conditions within layered system.

The insulation provided by clothing system is usually expressed in terms of a coo units and its distribution of the body, directly affect convective, conductive, and radiant heat loss from the skin to the environment Evaporated heat loss is dependent upon fabric permeability, the amount of body surface area covered by clothing, and the pumping of air between the body and garment layers. Persons at low to medium activity levels, dressed in conventional apparel in door environments, usually do not lose a large amount of heat through evaporation. Thermal manikin technology is used to measure the resistance to heat transfer provided by clothing systems. The reciprocal of this value, 6.45 W/m2.$^{\circ}C$ is often used in calculations for convenience. The purpose of this study was to implement a research program for calculation the insulation value (clo), body surface area and basal metabolic rate of selected clothing system. The project provided for the building of an insulation data base for use in evaluating and comparing new and improved garments.

Hwangnamdaechong Tomb (The 98th tomb in Hwangnam-dong), one of the royal tombs located around the area of royal tomb of King Michu in Hwangnam-dong, Gyeongju, is currently designated as Historic Site No. 40. It is assumed that Hwangnamdaechong Tomb is a royal tomb of the early 5th century. This study aims to examine the fabric relics excavated from Hwangdamdawchong Tomb and currently housed in Gyeongju National Research Institute of Cultural Heritage. The types of fabrics excavated from Hwangdamdawchong Tomb include plain silk, warp-faced compound woven silk, and hemp cloth. Most of these fabrics are adhered to metal products that became rusty. Plain silk found in Hwangnamdaechong Tomb can be divided into four types by its weaving method. Geum excavated from Hwangnamdaechong Tomb is typical Gyeong Geum that uses colored warp for its base and pattern. It is plain Gyeong Geum that the binding weft and warp is plain woven. Although there are a lot of Gyeong Geum fabrics whose colors are hard to define due to yellowing after long years, there are still many fabrics whose color such as purple, red, blue, and green can be identified. As literatures have shown that p cloth as well as silk were frequently woven during Silla dynasty, tremendous amount of hemp cloth was excavated. Most of the hemp cloth has S-twist in the warp and 8-12 seung degree of delicacy.
