도자기 복원에 사용되는 합성수지는 노화 현상과 유물 손상 가능성 등의 이유로 새로운 재료 및 복원 방식 연구의 필요성이 나타났다. 본 연구에서는 최근 연구되고 있는 3차원 디지털 기술을 활용한 복원 방식에 추가로 풀 컬러 3D 프린터를 접목하여 색상 정보를 지닌 결실 부를 출력하고자 하였다. 물성 실험을 통해 물성을 알아보고, 백자발과 분청사기접시를 대상으로 결실부를 출력하여 색도 및 광택도를 비교하였다. 실험 결과, 출력물은 기존 복원 재료와 인장강도는 유사했으며 압축강도는 약 1.4~2배 높게 측정되었다. NIST에 의한 색차 값 평가표에 의하면, 백자발은 ΔE^*ab 1.55로 눈에 띄는 정도, 분청사기접시는 3.34로 감지할 정도로 나타났다. 프린터의 한계로 정확한 색상 표현은 불가능하였지만 비접촉식 방식으로 손상 가능성을 최소화할 수 있었다. 손상 가능성이 높은 대상물에 적용하거나 결실부의 의도적인 색상 구별을 통해 전시효과의 목적 등으로 활용이 가능할 것으로 판단된다.

Expressionism, is as diverse as the artists invo)ved, in a very broad sense two main tendencies may be noted. The first is that of the Action painters, concerned in different ways with the gesture of the brush and the texture of the paint. It included such major artists as Arshile Gorky, Jackson Pollock, Willem De Keening, and Franz Kline. The other group consisted of the Color Field painters, concerned with the statement of an abstract sign or tranquil image in terms of a large, unified color shape or area. Here must be included Mark Rothko, Barnett Newman, Ad Rdinhardt, as well as, to a degree, Adolph Gottlieb, Robert Motherwell, and Clyf(ord Still. In this paper, 1 selected two artists Arshile Gorky and Jackson Pollock independent charac-teristics and studied the influence of their Action painting on the fabrics of modern fashion. However, it should be noted it was never the intention of the critic Harold Rosenberg, in coining this term, to imply that Action painting was a kind of athletic exercise. Nor is it true that the furious and seemingly haphazard scattering of the paint involved a completely uncontrolled, intuitive act. There is no question that, in the paintings of Jackson Pollock, Arshile Gorky and many of the other Abstract Expressionists, the element of intuition or the accidental plays a large and deliberate part; this was indeed one of the principal contributions of Abstract Expressionism which had found its own inspiration in surrealism's 'psychic automaton'. However, nothing that an experienced and accomplished artist does can be completely accidental. Aside from their intrinsic quality, the spun-out skeins of poured pigments contributed other elements that changed the course of modern painting. There was the concept of the all-over painting, the painting seemingly without beginning or end, extending to the very limits of the canvas and implying an extension even beyond. The feeling of absorption or participation is heightened by the ambiguity of the picture space. The colors and lines, although never punctur-ing deep perspective holes in the surface, still create an illusion of continuous movement, a billowing, a surging back and forth, within a limited depth. To study the influence of Abstract Expressionism on the fabric of modern fashion, 1 selected and examined four fashion magazines: Collezioni published in France, Bazaar in Italy, Gap in Japan and Vogue in the U.S.a. froim January 1989 to June 1991. As a result of this review I found that some fabrics used in modern clothing are printed in a dripping, pouring and splashing style without any meaning or form. Slides included in the presentation show that modern fabrics which are printed in such a style were influenced by Abstract Expressionism. The slides also show that these abstract prints are well suited to modern fashion design.

The purpose of this study is to find out the various impressions that tone-on-tone coloration of shirts and ties gives. This experiment was based on the $2\times4\times4\times2$ factorial designs; colors (purple and green), shirt tones (vivid, light, dull, and dark), tie tones (vivid, light, dull, and dark) and perceivers' genders (male and female). The materials in the experiment developed for this study were composed of various stimuli and the response scales for each stimulus. The stimuli were 32 upper body photographs, which were color printed by CAD system (4D-box program). We unified those colors of shirts and ties, and then made shirt and tie tone different. 27 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate the impression. The subjects of this research were 192 male and 192 female college students in Gyeongnam province including Jinju City. The data was analyzed by using SPSS program. Analyzing methods were one-way ANOVA and LSD test. The items of the adjectives were classified into 5 impression dimensions; potency, activeness, attractiveness, visibility and tenderness. In conclusion the impression through matching shirts and ties could be varied by the colors and the tones of shirts and ties. This study can be used as the basic color data in the males' clothes market which gradually pursuits high-quality, personality, and variety.

This study is on the abstract expressionist techniques among the art activities variously expressed in modern fashion. Its significance lies in making fashion artistic through the combination of fashion and art in contributing to the development of creative fashion culture. In terms of method, documents are used to characterize the concept of abstract expressionism, the works of representative artists, and the panting techniques in relation to modem art based on existing literature. Fashion-related anthology, domestic, and foreign fashion magazines were used to analyze the abstract expressionism applied to modern fashion since 2000. According to the findings, the abstract expressionism applied to modern fashion showed artistic expressions with the abstract beauty by chance, using only the images or techniques similar to those in abstract expressionism. Expressionist works had abstract and dynamic images, as they were given a third dimension through the process of being worn on the human body. Second, details or decorative factors were excluded to ensure the maximum space for expression, modem images were displayed using the simple forms such as silhouettes (spacious or dense) and the beauty of harmony was shown that had beauty emphasized by the expression effects of textile design, the division of space, and the composition of colors. Third, the action painting techniques in modern fashion were used for textile designs printed on the surface of clothes, and the dynamic character of the design was shown by the duplication and juxtaposition of stains created by chance. The color field abstract techniques were shown through printing, texture, and dying, in addition the intense and pure abstract images were displayed by treating clothes like large screens.

The purpose of this study is to develop 3D pattern textile design of traditional Jogakbo motifs and fashion products using it. As a research method, first, through literature review, the three-dimensional representation of geometry on a plane with Jogakbo, design cases were examined. Second, through a survey, the purchase perception and design preference of Jogakbo cultural products was analyzed. Third, based on the results of the survey on color and print, the 3D pattern design for each type of Jogakbo is printed, and then textile fashion cultural products were developed. The results of this study are as follows. First, the reason why the public was not attracted to the purchase of cultural products was disatisfaction with practicality, unsuitable preference, price adequacy, aesthetics, and originality. Therefore, it was analyzed that quality, practicality, price, carry-on storage harmony and manageability, as well as aesthetic design were important factors for consumers. Second, the stereoscopic space on the plane expanded the two-dimensional plane space by forming a cube through the division and dissolution of geometry could be visualized using color expression of cubes of different brightness depending on the direction of light. Third, Jogakbo had eight types consisting of four detailed forms and three arrangement methods. The 3D pattern design could be developed through regular disolution and stereoscopic construction using Jogakbo's representative images for each type. In addition, it was found that it was easy to produce Jogakbo fashion products suitable for modern people through 3D pattern digital textile printing applying traditional colors.
