The color mixture, obtained from Indigo and Japanese pagoda tree, was applied to cellulose fibers such as cotton, linen and rayon to diversify color gamut of natural dyes. The color mixture was tried with two different methods. The first process was that cellulose fibers were dyed with $5{\sim}25%$ owf Japanese pagoda tree solution, and then dyed 1 to 4 times with Indigo. The second process was dyeing 1 to 7 times with Indigo, followed by dyeing with $5{\sim}25%$ owf Japanese pagoda tree solution. K/S value of the dyed fibers with one colorant and color mixture increased in the order of linen, cotton, rayon. It was also found that the first process could give higher K/S values than the second process.

Consumption value has widened, not only in functional but also aesthetic aspects, and consumers have started to find products that are more individual and emotional. The pattern of natural motifs meets the needs of consumers, and the marble is also widely used in patterns as one of the natural motifs. In this study, we analyzed many fashion items and other products with marble patterns based on the elements of CMF design, which are important points in merchandise design. For research, data on marble and its patterns have been found in professional books about marble. Foreign and domestic cases were investigated from well-known design exhibitions. Results of the study demonstrate the potential for pattern representation that stimulates consumers' senses by using color or material to express a variety of visual patterns, and using many finishing methods to express textured patterns. However, most of the domestic cases have only imitated the visual features of marble patterns, and very few have expanded the scope of the use of the patterns. A domestic research study was conducted only on the chemical features of marble, while research on the color and design of the visual aspects has been conducted passively. Therefore, This study will attribute designers to come up with creative pattern design and secure many consumers. Above all, we hope that the expansion of material representations will help designers break away from today's stereotypes of the characteristics of the materials and emotional expression.

Cylindrical fine-ceramics, $Al_{2}O_{3}$, was lapped on its outer surface by vibrational lapping unit manufactured in the laboratory. Cylindrical lapping of fine-ceramics is necessarily be characterized and optimized because its process as other finishing methods is time-spending and, so, inefficient one, and because it is very complicated and random process affected by numerous factors in itself and in its environment. In this study, an efficient experimental approach, experimental design method, was used to analyze characteristics of the cylindrical lapping of fine-ceramics, $Al_{2}O_{3}$, and response surface methodology(RSM) to find out the optimal variables combination for the maximum improvement of surface roughness($R_a$). From the final surface roughness point of view in the given lapping conditions, a stationary point or optimal lapping conditions as well as the possible maximum improvement of surface roughness($R_a$) was predicted.

This study analyzes interior features of indoor community facilities, focused on apartment complexes in capital area selected by 'Award of best living apartment' during $2000{\sim}2007$. First we analyze community facilities' concept, present standards of installment, present condition, then the size of each complex compared with legal standards. Also, we analyze interior features(spacial layout, furniture and furnishings, interior finishing materials, interior color), too. Research methods included both data survey and site visiting inquiry. Data survey method analyzes size of each complex using community facilities' floor plans, and site visiting inquiry analyzes type and feature of community facilities. Survey target was total 11 complexes, 7 in Seoul, 4 in Gyeonggi-do. The result is as follows. 1) It is needed to improve legal standards of installment, and to provide space with flexibility and changeability in order to allow alternation of usage purpose by resident's claim. 2) To determine size of community facilities, we must planned not only by the number of households, but by legal standards of supply according to the number of households, the rate of net area, and the recommended size per person. 3) The area of community facilities in apartment complex that residents use doesn't considered user's convenience. So it us needed to add each facility's recommendation in response to user's needs.

The purpose of this research is to investigate the actual wearing conditions of working uniform and identify problems for the aircraft mechanic. For this study, questionnaire surveys were conducted dividing according to styles of clothing; one-piece and two-piece styles. Subjects were 343 men working in flight line. Questionnaire of 159 two-piece styles and 184 one-piece ones were used in analysis. The results of the study are as follows; The result about wearing each type of working uniform showed that the two-piece one is always as the air force uniform, whereas the one-piece one is worn only a few times. They felt inconvenience during all operations except in the sitting position, crawling position, and positions in which they were using tools. Accordingly, the result of the functionality reported dissatisfaction on all question items. Therefore, uniform of two-piece style achieved better results on all questions related to motional flexibility and functionality. Questions on changes to finishing methods showed that each airline employed different methods for both two-pieced and one-pieced uniforms. The answers about the unstitched or worn-out parts of the two-piece garments showed that pants were unstitched on the inner seam of the trouser leg and hip regions, but the upper one was not. In case of the one-pieced uniform, the parts of wearing out is the seam of hip and the unstitched parts are knee region and hem line of pants. Questions concerning their satisfaction with the material of uniforms indicated a high rate of dissatisfaction, particularly in its ventilation and absorbency. Questions concerning the preferred design of working uniform indicated a preference for two-piece uniform rather than one-piece ones.

The present study examined the formaldehyde (HCOH) emission characteristic of various wood-based panel used in interior design, and measured changes in formaldehyde emission when a number of VOC reduction methods were applied. Formaldehyde emission showed a clear tendency of increase with the rise of temperature, and the concentration of formaldehyde emitted changed according to the preprocessing condition before measuring. Formaldehyde emission from wood board after bake out treatment was lower than that of the control group. When specimens were coated with urethane, cashew, water, oil stain, they generally showed the decrease of formaldehyde emission, although varying according to finishing material, and when edge sealing was applied the decrease became significant. $TiO_2$ coating was more effective in decreasing formaldehyde under ultraviolet lamps than under ordinary lamps. When the irradiation of ultraviolet lamps gets longer, formaldehyde emission decreased.
