Korean traditional paper 'Hanji' made from the bark of the paper mulberry tree is a good handicraft material because of its high viscosity, durability, dyeability, toughness, flexibility, plasticity, and manipulability. Hanji has been used as a textile material such as cotton wool for protection and keeping us warm from cold weather. However, Hanji has many limitations, while other textile materials have many advantages of such as washability, being sunproof, and fast coloring. The purpose of this study is to review physical properties, formation ability, and dyeability of Hanji as a material of fashion accessary. The contents of this study are composed of 5 parts: 1. To introduce the necessities of this study, 2. To review a historical background of Hanji and to identify its physical characteristics as a fashion accessary material, 3. To review and to compare techniques such as bonding, quilting, knitting, creasing and holding, twisting, folding & braiding, paper pasting, coloring & cutting, and outwashing(?) in making Hanji fashion accessaries, 4. To review dyeing and finishing techniques to increase commercial value, 5. To identify the best fashion accessary materials made of Hanji. The most important characteristics of Hanji as a fashion accessary material are its toughness in a wet state, fast color fixing, and flexibility. Especially weaving and knitting are considered as the most desirable techniques to make fashion accessary products stronger and more practical.

The culture and society environment plays major role in the development of Fashion and now in the 21st century, interest in Fashion is getting increased along with the rapid progress of advanced media development and information surge. Now it s the time to extend visual efficiency not only transmitting fashion image but also develop a creative product that satisfy the demander s needs. Currently it is very hard to express our subjective Korean "nationalism" in the Fashion since the various expression skill using western fashion illustration are dominant in our society. I have classified two components, fashion illustration and Korean painting in the theoretical circumstance. In fashion illustration circumstance, I examined the concept, usage, expression skill and history referring to historical documents. In Korean painting section, I considered coloring portrait concept, pattern, history, concept, and feature of the four gentlemanly plants. including the basic material of Korean-paper, Writing- Brush, Ink-Stone, Traditional-ink and also the history of itself. I have designed 8 products applying the concept of plum blossoms, orchids, chrysanthemums and bamboos that represent the most important part of the four gentlemanly plants, and also the expression skill of Korean coloring portrait.rait.

The present study attempts to examine the degree of recognition of the Personal Colors by the age of the woman, and to analyze the influence of the recognition on the factors for choosing specific colors for hair coloring and facial make-up and the consequent satisfaction. The data will be used as a basic material for research and marketing in the field of color consulting in the beauty industry. Collected data were statistically processed using the SPSS WIN program. Depending on the nature of the contents to be analyzed, either the percentage calculation or the Chi-square analysis or the ANOVA was carried out. The findings of the study are as follows; The overall recognition of the Personal Colors was generally low in terms of the knowledge, information and experiences. While the degree of recognition was the highest in teenagers, the necessity of diagnosing the Personal Colors was most deeply perceived by the women in their 30s. One of the factors for choosing a specific color for hair coloring was their favorite color for the teenagers, and the Personal Color or the advice of the professional for the women in their 30s. Meanwhile, the highest factor for those in their 20s was the colors in vogue. For the facial color make-up as well, this sensitivity to popular colors was also highest in the twenty-something women. The color choice in consideration of favorite colors and the Personal Colors was the most prominent in the teenagers. The tendency of utilizing the advice of sales people or the professionals was the highest in the women in their 30s. In the survey of satisfaction with the chosen colors for hair coloring and make-up, it was found that satisfaction was the highest in the cases of choosing the Personal Colors in all the age groups, while it was the lowest for the choice of popular colors.

This study aimed to develop epoxy putty as a multi-purpose connection and restoration material that can be used for material-specific restoration work such as metal, wood, ceramics, earthenware and stone artifacts by replacing synthetic resins currently being used for preservation treatment of cultural assets. Existing synthetic resins have the issue of cutting force resulting from high strength, deflection resulting from long hardening time, contaminating the surface of artifacts through staining on tools or gloves and need for re-treatment resulting from material discoloration. Accordingly, paste type restoration material most widely being used in the field of cultural assets preservation treatment was selected and examined the property to select it as an object of comparison. Based on such process, epoxy putty was developed according to the kind of agent, hardener and filler. For the purpose of solving the issues of existing material and allowing the epoxy putty developed to have similar property, property experiments were conducted by selecting agents and hardeners with different characteristics and conditions. The study findings showed that both kinds are paste type that improved work convenience and deflection issue as a result of their work time of within 5~10 minutes that are about 3~10 times shorter than that of existing material. In regards to wear rate for increasing cutting force, it improved by about 3 times, thereby allowing easy molding. For the purpose of improving the issue of surface contamination that occurs during work process, talc and micro-ballon were added as filler to reduce the issue of stickiness and staining on hand. Furthermore, a multi-purpose restoration material with low shrinkage, low discoloration and high cutting force was developed with excellent coloring, lightweight and cutting force features.

A study was made on the processing of domestic blast furnace slag by flotation and chemical purification for the use of slag as a raw material in making soda lime glasses. Feasibility study has been made for the use of reprocessing slag as a source material for both coloring and chemical components (such as CaO, $Al_2O_3$, MgO and etc.) in the glass making process. Chemical composition of chemically purified slags ranges; $SiO_2$ 34.5~37.5, $Al_2O_3$, 16.2~14.1, $Fe_2O_3$ 0.33~0.14, CaO 34.5~38.8, MgO 4.0~5.2, NmO 0.16~0.39, $TiO_2$ 0.23~0.35, S 0.08~0.42, ignition loss 3.3~8.4 and others 0.48~0.51%. It was found that either amber or greenish color could be easily obtained with the addition of salg up to 24%, however the slag addition to glass batches much impaired the transmitancy of glass products, thus a glass made with 7% slag addition showed 82% in transmitancy value at 510 nm.

The purpose of this study was to suggest effective teaching method of fashion illustration based on the results of examing the use of fashion illustration required by fashion designers and the ways of teaching used by professors teaching fashion illustration. The methods of this research were based on questionnaires. Questionnaire I was responded by 73 fashion designers working for fashion industry. Questionnaire II was answered by 52 professors teaching fashion illustration in colleges and universities. The results were as follows 1. In the examination of fashion illustration used by fashion designers in fashion industry, the flat was found to be most frequently used for market research, design sketch, presentation and specification. The illustration of wearers' form for making trend maps. So the flat was found to be the method that is most used by fashion designers. As for the coloring materials, markers were most frequently used that are of easy use, and the texture was mostly expressed by attaching fabric swatches. Two or three body poses are used for each style of clothing. 2. The effective teaching methods of fashion illustration that fashion designers and professors teaching fashion illustration consider are first, to teach the flat more precisely, second, to increase use of markers as coloring material, third, to teach various types of model poses. And fourth, the texture needs to be a little bit less expressed by focusing only on the effects because fabric swatch is used.

Cobalt (Co) compounds have been used for centuries to impart rich blue color to glass, glazes and ceramics. Cobalt monoxide (CoO), an oxide of Co, is an inorganic compound that has long been used as a coloring agent in the ceramic industry. Unlike other coloring agents, CoO can be used to develop colors other than blue, and several factors such as its concentration in the glaze and firing condition have been suggested as possible mechanisms. For example, CoO produces a typical blue color called "cobalt blue" at very low concentrations such as 1 wt% in both oxidation and reduction firing conditions; a higher concentration of CoO (5 wt%) develops a darker blue color under the same firing conditions. Interestingly, CoO also develops a purple color at high concentrations above 10 wt%. In this study, we examined the applicability and mechanism of a novel purple glaze containing cobalt(II, III) oxide, one of the well characterized cobalt oxides. Experimental results show that an Augite crystal isoform (Augite-Fe/Co) in which Fe was replaced with Co is the main component contributing to the formation of the purple color. Based on these results, we developed a glaze using chemically synthesized Augite-Fe/Co crystal as a color pigment. Purple color glaze was successfully developed by the addition of 6~15 wt% of $Co_3O_4$ to magnesia lime.
