The purpose of this study is to grasp the characteristics by image type in interior color. This experiment is carried out by the evaluation method of color simulation with the color image processor. And the result of this experimental evaluation is analyzed quantitatively by HAYASI 1 Program. The results of this analysis are as follows : 1) In casual and clear images, the most main colors are GY, PB, Y , and N, Casual image has high chroma and the most arrangement of colors is hue-contrast or contrast -harmony with white. Also the main colors of clear image are in identical or similar harmony with the hues of floor. 2) In romantic, elegant, pretty, and gorgeous images, the most main colors are GY, RP, R , YR and Y and the most arrangement of colors is identical or similar harmony. The romantic image of pastel tone is wholly lighter than the pretty image of bright tone. And elegant image is lower in chroma than romantic images, so generally dark. Also gorgeous image is the vivid tone with high chroma. 3) In chic and modern images, the main colors are the hues of B, PB, high value and low chroma with bright tone. Also, the main colors are in identical or similar harmony with the hues of floor : BG , B, PB and P. 4) In natural and semiclassic images, the main color is the warm color of Y, YR and the most arrangement of colors is identical or similar harmony. Also Semiclassic images is the dull tone with middle value and middle chroma and darker tone than natural image. 5) In dynamic image, the main color is the hue of N, Y, PB and GY and most of color is high chroma. And the most arrangement of colors is value-contrast.

The purpose of this study is to check color change, color fastness, increase wt., antibiosis, and UV-protection efficiency depending on gallnut concentrations and mordanting methods, when silk fabrics dye with gromwell according to pH. This results will contribute in developing of natural mordant with multi function. The results are as follows. ${\lambda}_{max}$ of Gallnut extracts was near 299 nm. When gallnut was used as a mordant, at all pH levels, pre-mordanted fabrics had red color and post-mordanted ones had red-purple color which was closed to natural color of gromwell. Brightness of post-mordanted fabrics was higher than that of pre-mordanted fabrics. In the case of chroma, pre-mordanted fabrics was higher than post-mordanted fabrics. There was no significant difference of color, brightness, and chroma depending on gallnut concentration. As mordanting concentration increased, fabric weight gradually went up and increase weight reached maximum $17{\sim}19%$. At all pH levels, color fastness improved by pre-mordanting and post-mordanting, and it showed the maximum $4{\sim}5$ grade of wet fastness and 5 grade of dry cleaning. Antibiosis of silk fabric was improved by gromwell dyeing and synthetic tannin mordanting. Antibiosis of gallnut extracts was excellent. The color fastness and antibiosis were preserved after 10 cycle dry cleaning. UV-protection efficiency was excellent by dyeing with gromwell and mordanting with gallnut.

The typical instrumental assessment of ununiform natural soils has been carried out by yellowing of the specimens instead of the surface reflectance or the calculated formula. However, the regular instrumental area of sample holder is necessary for the measure of yellowing. Therefore, this study attempted to apply image analysis which had full color image by scanning of one time without limitation of instrumental area. The test samples were analyzed pseudo and full color image. This paper evaluated soil with hue of yellowing and gradation of gray level with color image analysis. Then, it was studied propriety of image analysis with correlation of yellowing, hue and gray level. Ultimately, the proposed image analysis in this paper was advanced method against the typical instrumental assessment.

To get a variety of colors on silk fabrics with natural dyes, mordanting and combination dyeing were carried out. Gromwell, sappan wood, safflower were used as the three primary colors for combination dyeing. Metal compounds containing alum and iron were used as mordanting agents. In combination dyeing of safflower and sappan wood, safflower and gromwell, gromwell and sappan wood, various colors were obtained according to the content of dyes used. Safflower/sappan wood dyeing showed different colors between yellow red and red purple of Munsell color circle such a YR, R and RP. And safflower/gromwell dyeing showed R, RP, P and PB Munsell color circle and then gromwell/sappan wood showed R, RP and P. As the result of these experiments, wide range of colors (YR-R-RP-P-PB-B) were obtained according to various mixing portion of safflower, gromwell, sappan wood, dyebath pH and repetition dyeing.

In this study, improving the wash and rubbing fastness of a natural coloring matter from Madder extract dyed on Tencel nonwoven. The cationic finishing agent(RBP), nonionic finishing agent(HPX) and mordant(PAW) were used to improving the color fastness. The two types(exhaustion and pad-dry-cure) finishing process were investigated with various finishing agent concentration. The color strength, wash and rubbing fastness of Tencel nonwoven dyed with Madder extract have been evaluated by various dye concentration and finishing agent. The exhaustion process treated with the cationic finishing agent(RBP) was effective to improving washing and rubbing fastness.

In order to development of culture goods I made works with various color's silk fabrics dyed with water extract or methanol extract of plants. The Plants used for dyeing as dyeing material were indigo, safflower, amur cock tree, onion's Peel, citrus peel, mugwort, gromwell, sappan wood. Each of Plants were extracted by each of temperature and time. The mordants used for various color chanties are aluminium sulfate, cupric acetate mono hydrate, ferrous chloride. With fabrics of various color dyed like this I made works which give expression to an easy and natural image of the Korean nation of fabrics.

The natural convection of a horizontal layer heated from below in a three-dimensional rectangular enclosure was dealt with both numerically and experimentally. The aspect ratios are 1:2:3.5 and Boussinesq fluid is water with the Prandtl number of 5.0. This experimental study showed how to measure the variation of temperature field in a 3-D rectangular enclosure with small aspect ratios by using TLC(Thermochromic Liquid Crystal) and color capturing technique. The experimental temperature field had periodic characteristics of 75 sec at Ra=2.37*10$^{5}$ . But the numerical convection flow had periodic characteristics of 79 sec at the same Rayleigh number. In three dimensional computation it was found that the convection roll structure bifurcated from four rolls to two rolls as the Rayleigh number is increased.

This purpose of present study was to examine the figures and colors of hanbok textile. The data were collected from 489 pieces selling at hanbok shops in Taegu pusan and were analysed. Result of this study was as follows: 1) Figures As the hanbok figures tradition figures were used a great many among the figures. The next was natural geometric abstract figures. The reactionism trend was worthy of notice in figures and traditional design occupied most of them. 2) Color In the hue, YR, R, RP group were used concentratedly. Because 5,6,7 level were used a great many among the value value was represented lightly more than midium light. Because 2,3,4 level were used a great many among the chroma chroma was represented duller than midium chroma. Thus hanbok color was used mainly in a several party and korean were tendancy to like natural the sence of color.

Simultaneous measurement technique for temperature and velocity fields near a heated solid body has been constructed. The measurement system consists of a 3-late CCD color camera, a color image grabber, a 1ighting system, a host computer and a software for the whole quantification process. Thermo Chromic Liquid Crystals (TCLC) was used as temperature sensors. A neural network was used to get a calibration curve between the temperature and the color change of the TCLC in order to enhance the dynamic range of temperature measurement. The velocity field measurement was attained by the use of the fray-level images taken for the flow field, and by introducing the cross-correlation technique. The temperature and the velocity fields of the forced and the natural convective flows neat the surface of a cartridge heater were measured simultaneously with the constructed measurement system.
