  • The objective of this study was to find in what color Korean handmade paper(Hanji) is dyed when it is dyed with a pigment extracted from waste onion peelings using different kinds of mordant, and how the paper is discolored and variety of strength under the condition of accelerated aging test. The results of this experiment are as follows. 1. Korean handmade paper was dyed in different colors according to the kinds of mordant. Mainly it was dyed in orange-brown, and sometimes in gold or khaki. 2. Korean handmade paper dyed was not discolored much, which suggests that the pigment is strong under the condition of aging. 3. As for durability, Korean handmade paper dyed in gold was strongest. Korean handmade paper, to which aluminum sulfate, iron sulfate or sodium dichromate was applied as mordant, had poor durability. Thus, these were not suitable as mordant.

  • The purposed of this study was to investigate the effect of Gold bonding agent as intermediate layer between metal substrate and ceramic coating. Gold bonding agent used to seal off any surface porosity, to mask the greyish color of the metal, and to provide an underlying bright golden hue to the ceramic coverage. The adhesion between metal substrate and ceramic is related to diffusion of oxygen during ceramic firing. The oxide layer produced on non-precious alloy anti titanium was considered to have a potentially adverse effect on metal-ceramic bonding. The oxidation characteristics of titanium and non-precious alloys are the main problem. Every group were divided into test and control groups. Control groups are carried out process of degassing for product oxide layer. Au coating was applied on each Ni-Cr, Co-Cr alloys and cp-Ti specimens with difference surface condition or degassing. Specimens surfaces and cutting plane was characterized by SEM/EDS. Results suggested that Au coating is effective barriers to protect metal oxidation during ceramic firing.

  • 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.

  • Stainless is widely used for various purposes due to its good corrosion resistance. There has been much research to produce the color stainless steel by several methods. In this experiment, TixN films have been deposited on the SUS304 substrate by the DC magnetron sputtering system and the color and texture of the films as a function of coating conditions has been studies. The TixN films showed a (111) preferred orintation in bias-free conditions. The texture of coated later was changed from (111) to (200) to (2200 with a change of the bias from -1000V to -3000V. When the bias is low, coated elements have low energy. Therefore, the texturct (111) of low surface energy. The mobility of atoms was increased with the increase of the blas and texture was changed to the other plane. Non-etched specimens all exhibited strong (111) texture. This result shows that (111) is a loose plane and of non-etched specimens all exhibited. High growing velocity of (111) of especially was main texture of Non-etched specimens. Low working pressure($4\times10^{-3}$torr) was more effective than figh working pressure ($6\times10^{-3}$torr) for the gold color of $Ti_xN$ film. L and b were increased and a was decreased with the increase of bias voltage. Accordingly, We obtained the near gold color of $Ti_xN$ film(L;92, a;1~1.5 b:24~29.50. As a result of reflectance. And as the bias increased, the reflectance was proportional to the increasing bias voltage, but we took the top reflectance when the bias voltage was -200V.

  • 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.

  • Gold threads mean thread made by metal, it is composed various material to gold leaf, adhesive and media. The making technique and using materials of Gold threads are different from region, it can be used to distinguish country of origin. So this study finds characteristics and making techniques for flat gold threads of relics. Standard samples are made of animal glue, lacquer, red lacquer and etc. This materials are based on the scientific investigation of cultural gold threads properties. Then traditional techniques were estimated by comparison and analysis of actual cultural properties and standard samples. As a result of investigating cultural properties, it is similar to the standard sample which are mixed with red soil additives. After analysis of SEM-EDS, it is detected to Al, Si, Fe. So it is to the conclusion that traditional gold thread is made of adhesive mixed with red soil to improve gold color better. And this ways are similar with china that uses animal glue and red soil to adhesive and different from japan that uses lacquer to adhesive. Through this study, it will be used to data and reference for reappearance and making techniques of traditional gold threads.

  • The in vivo effect of tyrosinase inhibitors in the melanogenesis of gold fish (jet black color) was evaluated by measuring surface color and observing melanin pigment. The fish was firstly cultivated in 0.9% NaCl solution for 1 week to induce melanogenesis, and then, it was transferred to each treatment group containing tyrosinase inhibitor. The fish was grouped into control. food additive group (addition of 5 mM glutathione, 5 mM cysteine, and 1 mM benzoic acid), microbial inhibitor group (addition of culture broth of Aspergillus oryzae in shiitake and glucose medium), and plant extract group (addition of the mixed extracts of green tea, beet, red chicory, and nameko). After 6 days, the fish was anesthetized by electric shock, and color of pectoral region, lateral region, and dorsal fin was measured. Hunter's L and b values of treated group were generally higher than those of control group, indicating that the tyrosinase inhibitors could inhibit the melanogenesis of the fish. Effect of plant extract was apparent, though relatively weak, not because it did not work in vivo, but because a sufficient amount of extract could not be added to fish globes. If a large amount of extract was added, fish gradually died due to a microbial contamination. Microscopic observation of melanin in lateral scale and dorsal fin showed that in the treated groups with tyrosinase inhibitors, the number of melanophore per unit area and the size of one melanophore decreased.
