The purpose of this study was to closely examine the history of glasses and their cases used in the middle and late of Joseon Dynasty and identify inherent quality of our traditional glasses cases through color analyses of glasses cases' material and shape. While theoretical examination was conducted based on the literatures of glasses and their cases that firstly appeared in around Japanese Invasion (Imjin war) of Korea in 1592, practical analyses were demonstrated on photos of glasses cases used in the middle and late of Joseon Dynasty collected from both museum pieces and the internet which were grouped into wood, fabric, paper, sharkskin, hawksbill and cow's horn in accordance with their materials. 623 color samples were abstracted from collected 159 glasses cases and quantity analyses on each material were performed respectively. Abstracted representative colors based on the result of color analyses were classified into the main materials and accessories' color scheme. The result of this study are as follow: firstly, both Yellow and Yellow Red were mostly used in main materials. In Fabric case's colors were widely used in embroidery and in animal matter material cases such as sharkskin, hawksbill and cow's horn, which can be used as itself or dyed, Green Yellow shown in high frequency. Secondly, accessories were analyzed into similarity coloration with main materials. From this finding, it turns out that our traditional cases have characteristic of similarity coloration between main materials and accessories. Red Purple and Purple Blue in high frequency in accessories used as an accent color. Finally, based on the analysis of hue and tone, while the middle and low value colors shown in very high frequency, the high-chroma colors hardly shown.

To develope natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the waste grape juice. Dyeing experiments were done under different dyeing conditions of dyeing time, dyeing temperature, pH and concentration of dyebath and mordants which were treated after dyeing. Experimental fabrics were silk, cotton, ramie and hemp. Color difference(${\Delta}E$) and Munsell's HV/C of the dyed fabrics and color fastness of silk dyed fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. The color differences of dyed experimental fabrics were very slightly increased with dyeing time and the color of dyed silk was light purple and the cotton, ramie and hemp was light red purple. The color differences of dyed experimental fabrics were decreased and the color became lighter with dyeing temperature increased. The color differences of dyed experimental fabrics were decreased and the color changed from light purple to blue with the pH of dyebath increased. The color differences of dyed experimental fabrics were slightly increased with the concentration of dyebath increased. The color of dyed fabric changed with the mordant treatment and were different among the experimental fabrics. On the whole, blue tone increased with the Al and Fe mordant and green tone increased with the Cu mordant. The color fastness of dyed silk fabrics to light, washing (change) and perspiration (change) was bad and color fastness to dry cleaning and rubbing were good.

In this paper, the white organic light-emitting diode(OLED)was fabricated using the DPVBi of blue emitting material and a rubrene of orange color of fluorescent dye by vacuum evaporation processes. The device structure of OLED was Glass/ITO/2T-NATA(15nm)/NPB(3nm)/DPVBi(3nm)/DPVBi rubrene[2%](10nm)/DPVBi(25nm)/$Alq_3$ or New-ETL(60nm) /LiF(0.5nm)/ Al(100nm). The device with the $Alq_3$, layer shows orange color, and the luminance of 1000cd/$m^2$ at an applied voltage of 10.4V. On the other hand, the New-En layer results in white color, CIE coordinates of (0.327, 0.323), and the lowered driving voltage of 5V for achieving the same luminance value.

Using a blue emitting DPVBi material and red dopant DCJTB, WOLEDs with and without green emitter C6 added in ETL or HTL have been fabricated. The chromaticity color index of WOLEDs without C6 depends strongly on the doping concentration. In addition, manipulating thickness of emitting layer is similar effect such as controlling weight concentration of dopant. While the white color of WOLEDs with C6 added in ETL or HTL depend on position of C6. WOLED of three colors added green dye have been shown turn-on voltage of 3.25V, and EL efficiency 3.05cd/A @9V, $8102\;cd/m^2$, CIE coordinates (0.30, 0.32).

Three thermally stable red dyes of azo, quinacridone and perylene derivatives were synthesized and dye-based color filters were manufactured for liquid crystal display. Aggregation behavior of the dyes and their spectral property in film state were investigated by concentration dependent spectroscopy and field emission scanning electron microscopy (FE-SEM). These dyes have remarkable difference on their aggregation behavior in film state. Such difference of aggregation behavior affects the spectral property of the film, and it can cause decreasing the transmittance of dye-based color filters.

The purposes of this study is to analyze the formative relationship between artistic eye-makeup and clothes design by focusing on the period from 2000 to 2010 and to find out the development direction of the next makeup design. This study considered formative theory to analyze the formative relationship between artistic eye-makeup and clothes design of $Marian$ $L.$ $Davis$ and $Marilyn$ $R.$ $Delong's$ theory, and analyzed the formative relationship between artistic eye-makeup and clothes design in an aspect of line and form, color and material, The results are as follows: First, the shapes of the artistic eye-makeup such as tear drops, and rectangular paisleys were similar with the form of clothes such as the hourglass, cylinders and mix-types. Second, monotonic color coordination mainly appeared and sometimes contrast color coordination that induced complex contrast coordination were apparent as well. Third, the objects of the artistic eye-makeup such as glitter papers, spangles and beads had similar features as the material of clothes such as silk and spangle, and contrast was partially used like colors. The results suggest that artistic eye-makeup and clothes have an organic relationship, and artistic eye-makeup is changed with formative elements of clothes.

Digital printing has been used in various industrial areas, including semiconductor manufacturing and textile printing. However, implications on ceramic textile have not been well established so far. Printing high-viscosity materials requires an understanding of their behavior. An inorganic high viscous material with a viscosity range of 20-30 cps is analyzed using a viscometer and through X-ray diffraction. In this study, a digital printer is designed and assembled using a high-viscosity material with software for PC control, resulting in reduced processing at a fast area velocity of $20m^2/hr$. The present study demonstrated that the printer is capable of controlling the shape of the drop mass to smear ink smoothly onto the ceramic surface under an economic budget. In addition, to avoid any difficulty in color management, the ceramic printer is equipped with an independent color management system designed to cope with images on a highly viscous material.

The purpose of this study was to provide a formative charateristics by analyzing aesthetic charateristics of Egypt costume expressed in contemporary fashion. The result of this study obtained through this process were as follows. Aesthetic characteristics were expressed as a primative-retro characteristics, and a erotic-retro characteristics and a decorative-retro characteristics. Based on these trends, this study analyzed formative charateristics in an aspect of form, color, material, and decoration. In the modern fashion, unlike the H-line silhouette given by a natural fit in the primitive retro, the erotic retro was characterized in the shape by a tight H-line silhouette. For the color, peach, yellow green, gold, light blue, red, and black were used as the main color. For the material, see-through, gauze, mesh, organdy, and tight vinyl were utilized to emphasize an erotic image and expose a body secretly. For the decoration, the characteristic of erotic retro using the simple or same colors frequently was the use of similar accessories colors matched with material colors. The decorative retro was characterized in the shape by a H-line silhouette connected as a part of clothing which applied passium and a greatly modified silhouette from an Egyptian simple style which was well-matched with splendid accessories. For the color, the broadest range of color changes was found from light pastel such as white, yellow, light pink, burnt orange, blue, purple, silver, gold, and red to strong vivid tones. For the material, modern materials such as organdy, tulle, leather, and furs were often used. For the decoration, passium, an eagle pattern, scarab earrings, a crown, a sneak-shaped coronet, and pictograph printed on the fabric were frequently used.
