This study is re-creational experiment of Goryeo gold-painted decoration based on the research of the gold remaining and gold painting technique on the two pieces of Goryeo gold-painted celadon and the three pieces of Chinese gold-painted porcelain on North Song period which ones have been owned by National Museum of Korea since 2007. For the observation of glue state and color developing ability, four kinds of agglutinative agent and gold powder were mixed over the porcelain sherds, then gradually fired from $100^{\circ}C$ to $1200^{\circ}C$. Visual effect and ideal temperature were measured. Among of them, oil and glue showed the best results in glue state and color developing ability. Through those results, the entire Goryeo engraved celadon were reproduced in modern facilities. Oil and glue were gold-painted over the glaze then it was fired at the ideal temperature 700 to $800^{\circ}C$. For observation the binding condition, the gold-painting cross section was looked by the scanning electron microscope (SEM). As the result, oil and glue did not make much difference in Agglutinative agent, but gold was good, the color developing ability, however, in the case of oil, the edge of gold is curled because of its interfacial tension, and it is not dried well at room temperature so the working property is not as good as the glue. Glue more effective in terms of work efficiency, but color developing ability to fall slightly in this experiment were able to see through.

Silk has always been coveted as the finest and richest of all fibers woven into cloth. The earlist woven silk fragments found to date come from the third century B.C. The filament created and spun into cocoon by the larva of the silk moth, silk was exported from China to Europe from as early as the third century B.C. Silk industry is export leading industry that guide national textile industry development after the 1960s in Korea. Korean silk industry reached to peak at 1975 is displaying appearance that export scale is decreased recently. Various kinds methods can be proposed for high value added in silk industry, the research about color is essential. The importance of color is increasing in modern textile and fashion industry. Color is important factor of textile and fashion industry because color affects strong influence in human's sensitivity. Silk fabric can give high added value developing high sensitivity color because dye ability is superior. In this study I planned the "Utility Silk Color Code 288" for efficient color management in silk industry. "Utility Silk Color Code 288" are attached the Munsell notation and dyeing data which can reappear the color when needed. This research constructs for insufficient domestic color infrastruction and expect that basic role to develop the competitive power for Korean silk industry.

It is required to estimate color reproduction accurately in printing. Because printing technology has been developing, and most people want to see the best color reproduction. Therefore many color reproduction methods, such as Neural Network, LUT(Look Up Table) have been proposed for a long time. However, these methods are required to measure a lot of samples of printing. In this paper, we propose a new method that prediction of color reproduction based on compensated Neugebauer model for dotgain. This method was significant to increase an accuracy of color prediction with simple process.

The purpose of this study is providing a systematic method of exterior, interior finish materials and color scheme for elementary school and the actual color plans of elementary schools in Busan was analyzed to support the study. As a powerful design tool, a finish materials and a color are very effective to alter the perception of a building and a view. Most of the school, a shape and a material of elevations are monotonous and uniform and it makes students are hard to attach to their schools. As a place for learning and school life, the inner space of elementary classroom needs to be considered very important. The new basic guideline for developing and planning of architectural design could be achieved by researching a current plan and a finish material in elementary school. As a result, this study will benefit in planning both the exterior and interior environments of color.

We developed a quantitative method for evaluating CEP(color expression power) in eye shadow. This method enables the cosmetic industry to measure CEP on an interval scales, so it is more accurate and reproducible than previous panel tests. Oil, colorants, Pigments and pearls are major factors affecting CEP in eye shadow formulas. We studied the oil effect on CEP using our unique method so CEP could be improved. We believe this method can be applied to other color cosmetics as well. In conclusion, we expected this method to be useful to formulator who want to improve the color expression power in color cosmetics. Additionally, we hope it will contribute toward developing the experiential know-how about color to scientific knowledge.

The aim of this study is to develop an effective dyeing process for black color on the silk fabrics, using natural Indigo, Madder, Amur cork tree, Alder, Logwood, and Gallnut. All natural dye materials were water-extracted, concentrated, and freeze-dried. Seven different processes were carried out and the color differences(${\Delta}E$) of black color with each process from the chemical black dyed fabric were compared. The light, washing, and rubbing fastness were evaluated. The black dyeing of the silk fabrics was well carried and excellent black color was obtained in every methods. The profound black color could be obtained by the subtractive mixture of the three primary colors of red, yellow, and blue in the order of indigo(blue) - amur cork tree(yellow) - madder or lac(red). Black color was efficiently obtained by iron mordant when logwood or alder fruit was used. The color difference(${\Delta}E$) from the black color with chemical dyestuff was the lowest in the indigo - amur cork tree - lac - iron method. Light fastness and washing fastness were excellent in all dyeing processes, showing grade 5. The fastness to rubbing was excellent as shown grade 5 in the dry samples of logwood - iron process and alder fruit - iron process.

This study researches functional arrangements for colors of work clothes - concentrating on the arrangements of lightness - for safety protection of workers at the job sites in the mechanical industry. To conduct such study, blue color (5PB) is selected for the CAD simulations on six arrangements of brightness based on two colors. The brightness ranges are of 5PB color (between 3~7.5) which are measurable by Munsell Conversion, and arrangements on lightness consisting of one arrangement of high lightness-gap, two of medium lightness-gap, and three of low lightness-gap. To analyze the data of color values after applying arrangements of lightness and to evaluate the levels of awareness regarding arrangements, the NCS colorimetric is being applied. Color palettes are based on the NCS notations, and then marked with color triangles. After evaluation, the visibility proves to be high when the arrangements contain high lightness at the top and bottom, and the arrangements with higher lightness-gap show higher effects in safety. Since this study tends to check factors of lightness, the other color factors were limited. Therefore, in order to apply these results at the job sites, integrated applications of such results will be very useful for developing safe working clothes in the future.
