Cotton and ramie fabrics were dyed with artemesia and gardenia dyeing solutions. The chroma values of the fabrics dyed with gardenia were higher than that of artemesia. The ramie fabrics dyed with gardenia showed higher chroma values than the cotton fabrics. The colors of fabrics were deeper in shade but their chroma values were improved no more by repetition of dyeing process in artemesia dyebath. The two ways of dyeing processes were carried out. In the first way, each fabric was dyed in 5 different concentration(1∼5%) of gardenia dyebath to get the fabrics dyed in different shades. After then the gardenia dyed fabrics were dyed again in the artemesia dyebaths. In the second way, the 5 fabrics were dyed in different shades by repetition of dyeing process in artemesia dyebath. After then the artemesia dyed fabrics were dyed again with the gardenia dyebaths. When the artemesia dyeing process was added on the fabrics dyed in five shades with gardenia, the color differences between five samples were slight. But when gardenia dyeing process was added on the fabrics dyed in five shades with artemesia, the samples showed different hue of colors between yellow and green of Munsell color circle. Like almost of fabrics dyed with Plants materials, the colorfastness to light and laundering of the dyed samples were poor. But the colorfastness to drycleaning was good.

On-board spectrophotometer has been widely used as a non-contact and non-destructive measurement system in many fields. In this study, we evaluated the effect with respect to the light of on-board spectrophotometer based on a comparison with the standard spectrophotometer and color information coordinate system. Red, yellow, green and blue color paper, which were the standard reflective color paper and Munsell color paper, were used for experiments. In order to compare between a standard spectrophotometer system and an on-board spectrophotometer system, each color paper was measured 20 times. We concluded that it is possible to develop a system regardless the effect of light if the light was supplied consistently and a calibration was performed exactly while we applied an on-board spectrophotometer to non-contact and non-destructive measurement system.

This study is to demonstrate purple color characteristics by analyzing various purple clothing from Antiquity to modern fashion. In this respect, both documentary and investigative studies have been performed. Through, the documentary studies, the changes and examples of purple clothing were scrutinized, and images of purple were classified based on the Color Image Scale. Purple color samples applied during a period from 1993 to 1996, were collected from 33 women's domestic brands, and the colors were measured by the CE 7000 spectrophotometer and analyzed by Munsell HV/C. The results were shown as follows; 1. In Antiquity, the symbolic value of purple was heavenly color, because it was a bearer of light, a sign of the epiphany of the gods. 2. With the advent of synthetic dyes, purples were in the vanguard. This chemical synthesis gave purple, historically a regal prerogative, to the people, and enjoyed a memorable vogue in the mid-mineteenth century. 3. The purple images in fashion were changed by the factors such as culture-art, technological advances, political-economical situations, sports ect., and appears in modern fashion romantic, natural elegance, classic, gorgeous, chic, and dandy images. 4. In the result of analytical study on women's purple dress in domestic market, 10PB hue and P tone were mosetly used from 1993 to 1996.

The purpose of this study is to examine the characteristics by design component elements of the facade in elementary school buildings after the 7th educational curriculum. This study choose twenty five elementary school as the subjects of the study. And among many elevations of building, an elevation that is alongside of the schoolyard is chosen because this elevation has the highest visual influence on passers-by. To begin with, this elevation is divided into the roof and the surface of a wall, The roof is divided into roof styles, existence of roof and materials. The surface of a wall is divided into design principles(balance, contrast, rhythm), the formal organization(basic elements and form, and transformation of form), the ornamental composition, materials and colors. The results of the research are summarized as follows: First of all, motifs of classical architecture were well expressed in this period and postmodern tendency had been shown until 2005. After Build Transfer Lease(BTL), however, tendency of classical architecture, contrast by the size of the form and base element by point disappeared. Instead, asymmetrical and flat tendency is expressed. Also, emphasized design of the building elevation appear by basic colors of Munsell, not motifs of classical architecture.

In this study, the dyeing of silk fabric with Polygonum cuspidatum extracts was investigated. The contents of this study are as follows. First, the proper dyeing conditions were investigated by measuring the dye uptake (K/S value) that depended on the dyeing conditions when silk fabric was dyed with Polygonum cuspidatum extract. Second, the brightness (L), hue, and chroma differences that appear after mordanting with Al, Cu and Fe were investigated by measuring the CIELAB and Munsell values. And third, the colorfastness and antibacterial property were measured. When the silk fabric was dyed with Polygonum cuspidatum extract, the proper dyeing conditions were a colorant concentration of 90% v/v, a dyeing of time 100 minutes, a dyeing temperature of $70^{\circ}C$, and a dyeing of pH 3. In mordanting methods, the dyeabilities of post-mordanting were higher than those of premordanting. The hue value displayed yellow (Y) and yellow-red (YR) in cases of pre and post mordanting. The C value decreased by the mordanting of Polygonum cuspidatum extracts. Generally the colorfastness of mordanted fabrics was improved by mordanting. The dyed fabrics showed a 90.6% of Staphylococcus aureus reduction rate, and the dyed and mordanted fabrics showed 97.1% bacteria reduction rate. The dyed and mordanted fabrics showed above 90.5% Klebsiella pneumoniae reduction rate, and Cu mordant revealed the most effective bacterial reduction.
