The portrait featuring Jo Ban(1341-1401), a scholar-official from the late Goryeo and early Joseon period, and his wife is the oldest surviving couple portrait in Korea. It is of great value in uncovering the clothing culture of the period given the limited number of historical artifacts and records. This study examines the historical clothing and textile patterns of Jo Ban's wife and reproduces them using 3D fashion design software program CLO. She wears jokduri, chima, and baeja over layers of jeogori, a mixture of traditional Korean and Chinese styles. Her clothing illustrates eight patterns-one flower, five geometric, and two cloud. Records and relics of similar periods show that flower and geometric patterns in her clothing follow the prevailing styles of Goryeo, while the cloud patterns are representative of early Joseon. These details are used to reproduce six different styles of Jo Ban's wife with CLO tools. Various visualizations of textile patterns are applied to materials, generating a more realistic look than her existing 3D character created with the portrait. Results of this study are expected to help promote the use of Goryeo clothing and patterns in numerous designs and enhance intuitive understanding of Goryeo clothing based on 3D visualization.

A new 2-D braided textile metal matrix composite was developed and characterized. The constituent materials consist of PAN type carbon fiber as reinforcements and pure aluminum as matrices. The braided preforms of different braider yarn angles were fabricated. For a fixed bundle size of 12K, three braider yarn angles was selected: $30^{\circ}$, $45^{\circ}$, and $60^{\circ}$. The braided preforms were infiltrated with pure Al by vacuum assisted squeeze casting. Through the investigation of melt pressing methods and the effects of process parameters such as applied pressure, and pouring temperature, the optimal process conditions were identified as follows: applied pressure of 60MPa, pouring temperature of $800^{\circ}C$. Using the measured geometric parameters, 3-D engineering constants of metal matrix composites have been determined from the elastic model, which utilizes the coordinate transformation and the averaging of stiffened and compliance constants based upon the volume of each reinforcement and matrix material.

The purpose of this study was to inves-tigate the economic performance of the textile industry for the Korean traditional clothes. The content of this paper had two pars; The first part was for the macroeconomic aspects such as location production employments and the produc-tion facilities of the textile industries. The second part was for the microeconomic aspects such as business type branding method fabric type R&D efforts sourc-ing and the distributional channel The major results were as follows: 1.) Most textile firms for the korean traditional clothes were located in Gongju for man-made fibers and in Jinju for silk fabrics. 2) The size of the textile industry in terms of the number of business produc-tion amount the number of employee de-creased during 1994 and 1995 due to the decreasing demand. 3) Over the half of the textile firms produced raw fabric products while only 20% of them were involved in additional dyeing and /or printing finish which re-sulted in low value added production 4) The R&D effort of the textile indus-try for the Korean traditional clothes was very low due to the market uncertainty lack of technological knowledge and most of all small size of the firms 5) Most raw materials for the textile in -dustry were imported with high(25%) tariff rates resulting in price increase and thus low competitiveness in the market. 6) The textile producers sole about the 70% of their products to the wholesalers while selling the rest to the retailers di-rectly. This showed the dual structure of the distribution channel in the textile products. These results suggested some implica-tions for the firms the policy makers and the researchers. The firms should develop new and improved products to increase and create consumer demand by intensive R&D efforts. The government policy ma-kers should give financial supports the firms with R&D investment and legal help such as lowing tariff rate for the raw ma-terials. The researchers from the academy could help the textile industry with the advanced technological knowledge and up-date information for the consumer fashion demand.

Since knitted textile products mostly do not require long span of time from the conception to the final products, they have lead the fashion trends during the recent decades. Developments in the textile engineering industries, and computer software and hardware industries have made the 3D virtual clothing software system easily accessible by the fashion/textile industry personnel. The simulated models of apparel products using the state-of-the-art virtual clothing systems are, however, not the replica of real-world garments. Moreover, the garments do not maintain fixed shapes during wearing. Deformations at low external stress lead to difficulties in predicting the behavior of the knitted garments. Therefore, there is a need to compare the differences in appearances, textures, or other related properties between simulated fabrics and actual fabrics. Three knit stitches including jersey, rib, and cable stitches are examined in this study. The differences between fluffy thick yarns and thin yarns are also compared using 3D scanning and surface reconstruction. Obtained three-dimensional data regarding the reconstructed knit specimens would help to build a data base for estimating the behavior of the 3D models of the knitted garments.

항공기 복합재료 날개 구조는 대부분 접착 혹은 패스너로 체결되어 있는데, 이러한 적층 구조 복합재료는 층간 강도가 취약하여 층간 분리가 일어나기 쉽다. 이러한 적층 복합재료의 단점을 보완하기 위해 두께 방향의 섬유를 보강한 3차원 직조형 복합재료를 통하여 강도, 손상 내구성, 충격 및 피로 하중을 향상시킬 수 있다. 또한, 자동화된 직조 공정에 의하여 단일 구조 near-net-shape의 프리폼 제조가 가능하기 때문에 공정 단축, 체결 부품 감소로 복합재료 전체 가격을 절감할 수 있다. 따라서 본 연구에서는 3차원 직조형 복합재료의 항공기 구조물 적용 가능성을 확인하기 위하여 3차원 프리폼의 기본적인 구조인 orthogonal(ORT), layer-to-layer(LTL), through-the-thickness(TTT) 패턴을 직조하고 이를 복합재료로 성형하여 압축 시험, 인장 시험, Open-hole 인장 시험을 하였다. 이 중 orthogonal 직조 복합재료가 인장 및 압축 탄성계수와 강도 모두 가장 높았으며 노치 민감도에서도 orthogonal 복합재료가 일방향 적층복합재료나 패브릭 적층 복합재료에 비하여 가장 우수한 특성을 보였다.

Garment design needs an iterative manipulation of 2D patterns to generate a final sloper. Traditionally there have been two kinds of design methodologies such as the flat pattern method and the pattern draping method. But today, it is possible to combine the advantages from the two methods due to the realistic cloth simulation techniques. We devised a new garment design system which starts from 3D initial drape simulation result and then modifies the garment by editing the 2D flat patterns synchronously. With this interactive methodology using real-time pattern deformation technique, the designer can freely change a pattern shape by watching its 3D outlook in real-time. Also the final garment data were given relative coordinates with respect to the human anthropometric feature points detected by an automatic body feature detection algorithm. Using the relative human body coordinate system, the final garments can be re-used to an arbitrary body data without repositioning in the drape simulation. A female shirt was used for an example and a 3D body scan data was used for an illustration of the feature point detection algorithm.

The purpose of this study is to implement the textile design applying the floral pattern shown in Korean traditional fabrics and the New-Hanbok Chulic Dress in 3D through a virtual fitting system. As a research method, first, we analyzed the floral pattern types of fabrics in the literature related to traditional Korean textiles. Second, we developed textile designs of traditional flower motifs using 13 extracted flower types. Third, we applied the floral textile designs to the 3D original form of new-Hanbok Dress produced based on design preference survey results. The findings derived through this study are as follows. First, among Korean traditional patterns, the type of flowers used in textiles were blossom of chrysanthemum, orchid, camellia, apricot, peony, peach, pomegranate, hydrangea, narcissus, lotus, plum, chinese rose, and rosa rugosa. Second, this study found that the value of traditional culture can be further increased by using traditional flower patterns as an infinite source of creative design. Third, it was confirmed that the new-Hanbok can be developed endlessly as a clothing design that combines various morphological modifications and patterns without departing from traditional designs. In the future, if the research on costume design using various items of traditional clothing and the development of textile designs based on traditional culture continues, the development of new clothes design that leads to the development of Korean traditional clothing culture and meets the sensibilities of modern people will be endless.
