The purpose of this study is to suggest the prediction model for the color design by the image types in the office interior. This prediction model of the color design is for the more comfortable environment by using suitable, various colors fitted with business functions. In this research, we carried out the evaluation experiment with the variables such as the color on ceiling, wall, floor and the harmonies of color schemes. We set the prediction index through the multi-regression analysis. And the prediction model was made by these results. The design methods by the prediction model are as follows. 1) The $\ulcorner$variable$\lrcorner$ image was deeply influenced by the value and chroma and it was marked high in low value and high chroma and the harmonies of contrast and different color. 2) The $\ulcorner$comfortable$\lrcorner$ image was related to the value and chroma and it was marked high in high value and low chroma and harmonies of homogeneity and similar. 3) The $\ulcorner$warm$\lrcorner$ image was greatly influenced by the hue and the harmony of color schemes, and it was marked high in the warm colors and harmonies of homogeneity.

The purpose of this study was to investigate the traditional costume colors in ancient Korea. The results of this study can be summarized follows : The traditional costume colors in ancient Korea was affected on Chineses goverment official\`s costume colors, specially in Tongil Silla Dynasty. Goverment official\`s costume colors were purple(紫), red(赤), yeoolw(黃), blue(靑). The traditional Korean colors for clothes were devided in the white costume for low class and the colored costume of high class. The traditional Korean colors for colthes became fixed in the later Chosun dynasty, According to developing of dyeing technic, the prohibition of red costume for low class made for wear red undercloth. And on account of costume color in sumptuary law occured the transition of costume color. As transition of costume color, yellow(黃) changed in light in light yellow(松花色), purple(紫) did in dark green purple(茶割) Also it was found that the traditional Korean color for clothes was many kinds of soft, deep, natural colors out of red(紫)·yellow(黃)·white(白)·black(黑)·blue(靑).

New high technology has been developing rapidly in telecommunication. That wanted to need a display which economical and useful color STN is satisfactory advantages for this condition, and it can control easy better than TFT, organic electroluminescence. But color STN has restriction on real time. Thus, in this paper, we want to control color STN with frequency transform method on converter.

Copper electroplating is a very popular and important technology for depositing high-quality conductor interconnections, especially in through silicon via (TSV). As this advanced packaging technique developing, a mass of copper and chemical solution are used, so attention to these chemical materials into the utilization and costs can not be ignored. An economical and practical real-time chemical solution monitoring has not been achieved yet. Either Red-green-blue (RGB) or optical emission spectroscopy (OES) color sensor can successfully monitor the color condition of solution during the process. The reaction rate, uniformity and quality can map onto the color changing. Hidden Semi Markov model (HSMM) can establish mapping from the color change to upper indicators, and artificial neural network (ANN) can be integrated to comprehensively determine its targets, whether the solution inside the container can continue to use.

This paper investigates the problems of grouping N products on an assembly line with an objective of maximizing the option grouping rate. Before developing a mixed model grouping algorithm, simulation studies are committed for developing operating rules and evaluating the layout production systems. A mixed model grouping algorithm is suggested and it is applied to the color selection lane in automobile production system, which reveals a high mixed model grouping rate.

A data structure representing 3-D objects was designed for the personal computer. It is very simple to be used in the personal computers which have small memory and low speed. A homogeneous transformation for developing 3-D objects was derived. Each developing procedure consists of five transformations : one translational-three rotational-one translational. Developing a solid is a creative work. So the results of developing vary with the order of surfaces to be developed. One method to reduce the length of seam was considered. The programs used in this study were written in Pascal and Assembly and a modeller that generates 3-D primitives was included. This program is an interactive dual-screen system. While all the menus in Korean are displayed at the monochrome monitor, the development figures with projective views are drawn at the color monitor. The program has wide applications for plate works.

본 논문은 표준 디스플레이를 이용한 OLED의 색재현성 모델링을 제안한다. 비표준 RGB 디스플레이의 종류는 매우 다양하게 있으며, 그 색 재현 특성은 삼원색 좌표와 기준 백색 좌표 등 여러 가지 요인에 의해서 다르게 나타난다. 본 논문에서는 변환 매트릭스를 이용하여 OLED 디스플레이의 색 재현 특성을 표준 디스플레이에 재현할 수 있는 알고리듬을 제안한다. 본 연구에서 제안된 알고리듬을 이용하면, 색 재현 특성을 사전에 시뮬레이션으로 확인할 수 있으므로, 기존 디스플레이의 성능 향상이나, 새로운 디스플레이를 개발할 때 매우 유용하게 쓰일 것으로 기대된다.

From the perspective of reducing the sampling cost of color images at high resolution, block-based compressive sensing (CS) has attracted considerable attention as a promising alternative to conventional Nyquist/Shannon sampling. On the other hand, for storing/transmitting applications, CS requires a very efficient way of representing the measurement data in terms of data volume. This paper addresses this problem by developing a measurement-coding method with the proposed customized Huffman coding. In addition, by noting the difference in visual importance between the luma and chroma channels, this paper proposes measurement coding in YCbCr space rather than in conventional RGB color space for better rate allocation. Furthermore, as the proper use of the image property in pursuing smoothness improves the CS recovery, this paper proposes the integration of a low pass filter to the CS recovery of color images, which is the block-based ${\ell}_{20}$-norm minimization. The proposed coding scheme shows considerable gain compared to conventional measurement coding.

The purpose of this study was to improve dye effect and method in order to facilitate the use of persimmon juice dyeing. Silk fabrics were pad-dyed to 100% pick-up using padding machine after dipping in persimmon juice extracted from unripe persimmons indigenous to Jeju. The color of dyed silk fabrics by padding method was more even and repeatable than that by traditional hand method. Persimmon juice concentrations were 4 types 10, 25, 50 and 100%. The silk fabrics were pad-dyed to 100% pick-up and were repeatedly dyed two times and three times with 100% concentration. The higher the concentration, the more color deepened. UV Irradiation instead of sunlight was applied to color developing. Irradiation times were shortened to 1-8hrs. Color values which reguired 30-50 hrs. in sunlight irradiation. were obtained in 3-5 hrs. with UV irradiation. Tensile strengths of silk fabrics in UV irradiation decreased but not decreased in sunlight irradiation. Elongations of silk fabrics in sunlight irradiation increased but decreased in W irradiation. Drape stiffness increased up to three times.
