This study is purposed to understand the usage of the color and the material pattern in detail and to apply for interior architecture. Many documents have prescribed the color and the pattern at random. While the usage of the color and the materials was ignored rather than architectural form, the importance of the color and the materials stands out in modern interior space. The villa, the weekend home of the Savoye family, was built between 1928 and 1931. Particularly, the villa Savoye was focused for this study. Le Corbusier viewed case pieces for storage and wall partition for division as architecture, and he units furniture and architecture by developing partition that could be painted either the wall color to become part of the wall or in contrasting colors to stand out as wall partition. He loved white and lie believed in using it for interiors, but noted that it should also be balanced with a wall related polychromy. Color became an integral part of white structure of the villa savoye that was raised on stilt with an exterior wall at the base painted green as a visual connection with the lawn. Color was used architecturally in the interior as well, with white walls interrupted by planes of pink, blue and red ocher and it gives the space an unexpected playfulness with tile color of the finishing materials. the various usage of the color and material patterns constitute an element of great architectural richness. They have a unique principle based on emotional order and make the man move to another space and experience the spacial connection.

The structure of current guides is largely illogical and without any rational use of color ordering. The shade guides are generally made of plastic (rather than the actual composite material) and do not accurately depict the true shade. translucency. or opacity of the composite resin after polymerization. To solve this problem, information based on evaluations of natural teeth and material that use the same method and experimental conditions is necessary. The present investigation measured the color of natural maxillary anterior teeth in vivo and compared the results with those of composite resins. 269 Korean subjects were selected for this study. Intact central incisor. lateral incisor. and canine were selected. The clinical crowns were free of caries or restorations. The middle site of the coronal portion on the labial surface of the tooth was measured by Chroma Meter. The five light activated. resin-based materials (Amelogen, Denfil, Elitefil, Spectrum, Z100) were used in this study. Resin composite was condensed into plastic mold with a diameter of 8mm and a thickness of 4mm. pressed between glass plates to flatten the surfaces. and polymerized using a Visilux II visible light activation unit. The surfaces were polished sequentially on wet sandpaper. Color measurements of each specimen were accomplished by Chroma Meter. A computer program that compares each tooth color with each composite resin color was written and the minimum CIELAB color difference ($\Delta$E$^*$) between tooth and each material was calculated. Under the conditions of this study: 1. Teeth tend to become darker with advancing age. 2. Canines were darker. more yellow. and less green than incisors. 3. The teeth from the women were lighter. more green. and less yellow than the male teeth. 4. In general. composite resins were lighter. more green. and less yellow than teeth. Deficiencies were noted in Hues in YR range. 5. Mean color differences between the five composite resin products and teeth were detectable to the naked eye($\Delta$E$^*$>1.0). 6. In comparing the mean $\Delta$E$^*$ values of materials. Spectrum showed the least followed by Z100, Elitefil, Amelogen, Denfil in increasing order.

The optical properties of multi layered thin films with $Sb_2O_3/Na_3AlF_6/Sb_2O_3/Cr$ were simulated by using EMP(Essential Macleod Program). EMP is a comprehensive software package to design and analyse the optical characteristics of multi-layered thin film. $Sb_2O_3$ and $Na_3AlF_6$ were selected as a high refractive index and low refractive index material respectively. Additionally Cr was chosen as mid reflective material. Optical properties including color effect were systematically studied in terms of different optical thickness of low refractive index material. The optical thickness of $Na_3AlF_6$ was changed as 0.25, 0.5, 0.75 and $1.0\lambda$. The film with 0.25, 0.5, 0.75 and $1.0\lambda$ of optical thickness showed mixed color range between purple and red range, yellowish green and bluish green, purple and mixed color range of green and purple respectively.

To develop natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the dyebath extracted from wisteria. Dyeing experiments were done under different dyeing conditions of dyeing temperature, pH of dyebath, dyeing time, concentration of dyebath and mordant treatment which were treated after dyeing. Experimental fabrics were silk, wool, cotton, ramie and hemp. Color difference(ΔE) and Munsell's HV/C of the dyed fabrics and color fastness of silk and cotton fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. In silk and wool fabrics(non mordant, dyeing time-20min), color differences increased in case of dyeing temperature of $100^{\circ}C$, but in cotton, ramie and hemp fabrics, color differences did not increase. Without mordant treatment, color differences of all experimental fabrics were about 10-20, so in wisteria dyeing mordant treatment was necessary. Color differences were increased by the mordant treatment; the color of dyed fabrics with Al mordant is dull yellow, Cu mordant is gold and Fe mordant is olive tone. Color difference was not affected by pH of dyebath in all experimental fabrics. On the whole, the color fastness of dyed silk and cotton fabrics were good, but color fastness to washing and perspiration in Fe mordant was weak and improved in Cu mordant.

PURPOSE. Surface color is one of the main criteria to obtain an ideal esthetic. Many factors such as the type of the material, surface specifications, number of firings, firing temperature and thickness of the porcelain are all important to provide an unchanged surface color in dental ceramics. The aim of this study was to evaluate the color changes in dental ceramics according to the material type and glazing methods, during the multiple firings. MATERIALS AND METHODS. Three different types of dental ceramics (IPS Classical metal ceramic, Empress Esthetic and Empress 2 ceramics) were used in the study. Porcelains were evaluated under five main groups according to glaze and natural glaze methods. Color changes (${\Delta}E$) and changes in color parameters (${\Delta}L$, ${\Delta}a$, ${\Delta}b$) were determined using colorimeter during the control, the first, third, fifth, and seventh firings. The statistical analysis of the results was performed using ANOVA and Tukey test. RESULTS. The color changes which occurred upon material-method-firing interaction were statistically significant (P<.05). ${\Delta}E$, ${\Delta}L$, ${\Delta}a$ and ${\Delta}b$ values also demonstrated a negative trend. The MC-G group was less affected in terms of color changes compared to other groups. In all-ceramic specimens, the surface color was significantly affected by multiple firings. CONCLUSION. Firing detrimentally affected the structure of the porcelain surface and hence caused fading of the color and prominence of yellow and red characters. Compressible all-ceramics were remarkably affected by repeated firings due to their crystalline structure.

A multielectrode electronic paper film capable of expressing a single-color image was fabricated by injecting color electronic ink into an electronic paper panel; on the basis of its reflective or transparent properties, it is possible to control the expression of six single-color images and their transmittance. In this study, a single-color image was represented by driving a multielectrode electronic paper film; color coordinates were measured. The six capable single colors were yellowish pink (0.444, 0.354), white (0.355, 0.352), black (0.241, 0.241), orange (0.514, 0.360), reddish orange (0.606, 0.338), and reddish purple (0.469, 0.145). Color particles used in this paper were black and white, by which six colors are accomplished, but more single-color images can be combined by using cyan, magenta, and yellow particles.

Actually, Cyberpunk is a compound word joined by cybernetics, which was used in control theory, and punk, was symbolized as anti-culture. Today, however, the definition of the term has been extended by various fields, used in many meanings. Therefore, the purpose of this study was to apply the Cyberpunk concepts to understand today　s fashion because understanding of the present fashion is a means to interpret our culture. For this purpose, the phenomenon of Cyberpunk in fashion was subdivided into three factors material, color, and style. The results of the study were as follows : First, the materials used were techno material, special print by computer for future feeling and geometrical pattern, optical pattern to improve visual effects. Second, the colors mainly used were silver, black and white, bright color, and off-color of computer animation to present future-oriented feeling. Third, the general styles used were fit and slim, simple and liner, dualistic style to express future　s image. In conclusion, the phenomena of Cyberpunk in fashion were expressed in material, color and style of fashion. Cyberpunk fashion was evident in T-shirts, sweaters, jackets, or as items of ornamentation such as pins, pendants, belts, and earrings, etc.
