SAR (Synthetic aperture radar) images are less affected by the weather compared to optical images and can be obtained at any time of the day. Therefore, SAR images are being actively utilized for military applications and natural disasters. However, because SAR data are in grayscale, it is difficult to perform visual analysis and to decipher details. In this study, we propose a color mapping method using RF (random forest) regression for enhancing the visual decipherability of SAR images. COSMO-SkyMed 2 and WorldView-3 images were obtained for the same area and RF regression was used to establish color configurations for performing color mapping. The results were compared with image fusion, a traditional color mapping method. The UIQI (universal image quality index), the SSIM (structural similarity) index, and CC (correlation coefficients) were used to evaluate the image quality. The color-mapped image based on the RF regression had a significantly higher quality than the images derived from the other methods. From the experimental result, the use of color mapping based on the RF regression for SAR images was confirmed.

In the millenium, which will be characterized by its global culture, a strong sense of identity of one's culture is needed to nature one's culture in a way that more people can participate in creating, enjoying and consuming it. In order to respond to both globalization and localization, natural and cultural backgrounds of such should be considered in the conversation of nature, so that the optical and color environment can have local identity while undergoing sustainable development. Therefore, the objective of this research is to enhance the image of a city, which is endowed with beautiful scenery and unique culture, but has lost its identity since industrialization An through a scientific and systematic color planning The Research was conducted as follows. First, color environment which doesn't reflect local characteristics due to modernism which emphasizes on uniformity was examined. Second, standard and analysis of environment color planning were examined. Natural color specimen was use to make a palette of nature colors, from which colors for architecture were extracted to come up with color combination types. Without traditional architecture philosophy, materials and colors, which were once in harmony with the environment, it is impossible to clean up the environment all together. However by using colors to control new city plans, urban redevelpment, construction and renovation gradually, that process can be effective and less costly.

The traditional Korean hand-made papers (Hanji) were dyed with colorant extracted from flowers of Sophora japonica L.(pagoda tree), and the effect of various dyeing factors (mordant, mordanting method, pH of dyeing solution, etc.) on colors and K/S values of the dyed Hanji was investigated. Changing mordant affected the color of dyed Hanji. Mordanting with alum, copper acetate made the color of dyed Hanji more yellow, but dyed Hanji mordanted with $FeCl_2$ had dark olive color. The K/S value of the dyed Hanji mainly depended on the pH of the dyeing solution and mordanting method. It was found that sim-mordanting with alum was timesaving and effective dyeing method. The dyed Hanji sim-mordanted with alum had the highest K/S value at low pH (about 4).

This study was conducted to develop a method to change the color of traditional Dongchimi using natural dyes to meet changing consumer demands. It was intended to improve the manufacturing process ability for color Dongchimi, and the best optimum extraction solvent and method from the natural dyes were proven to be confirmed and valid. The extraction process was evaluated using different solvents including distilled water, 20% ethyl alcohol, and 1% citric acid, and the quantity of the extracted anthocyanin was then measured based on the absorbance. The greatest absorbance was observed when 1% citric acid was used. Based on these findings, it would be most efficient to allow the traditional Dongchimi to produce citric acid naturally instead of using artificial additives during its production. Celosia cristata L. was extracted in its largest quantity when reacted with 20% ethyl alcohol. Therefore, instead of applying Celosia cristata L. to Dongchimi as the sub-ingredient during the preparatory stage, it will be more efficient to use Celosia cristata L. as the fractional ingredient in order to first extraction.

Unlike traditional lightings, LED lighting is one of objects that sends user an emotional segments through brightness control from various color temperature and dimming control. Also, within present interior lighting environment, emotional researches about traditional fluorescent lamp and newly implemented LED lighting environment are in active progress. Despite the fact adjectives describing emotions and scale modeling have been repeatedly used in many cases for a long time, there seems to be a lack of results in reliability, and there is a limitation for applying into actual lighting design. The purpose of this study is to construct an actual sized test-bed, which is used to draw out one's emotional words of behavior patterns from inner emotional experiences about lighting environment in an office space. Also, having fluorescent lamp and LED lighting as the main test subjects, we have tested emotional parts according to the changes of color temperature and adjective vocabularies chosen from user's action, and we have compared and analyzed the drawn out data. Also, having fluorescent lamp and LED lighting as the main test subjects, we have tested emotional parts according to the changes of color temperature and adjective vocabularies chosen from user's action, and we have compared and analyzed the drawn out data.

The objectives of this study were to examine how image evaluation and preference of women's clothing color vary according to perceiver's culture, gender, and clothing color; to investigate the differences of image evaluation according to body type and the clothing color; and to disclose what image affects to the clothing color preference of Korean and American. Subjects were 388 Korean and 363 American college men and women. The American evaluated the wearer more elegant, feminine, and neater than the Korean did. Clothing color gave significant influence on perception of all image variables. Koreans showed that red and blue color shirts were perceived to be individualistic. Koreans considered blue, indigo, purple, gray, and black were perceived to be less feminine. This means that they evaluated the colors of blue range and low chroma were masculine according to their traditional attitude. Women were more attracted by indigo and purple, while men tended to evaluate yellow as an appealing color. The evaluation of sociability varied depending on the perceiver's culture and clothing colors. The corpulent body type had negative evaluation rather than the ordinary one without the relation with the color of clothing for Koreans and Americans. The evaluation of sociability of Americans had an interaction effect by the body type and clothing color. Attractiveness gave the first significant influences on clothing color preference, and the next came individual(-) and splendid image for Korean men. The individual image gave Korean men to be negative effect. Attractiveness, elegance, and sociable image gave significant influences on clothing color preference in Korean women. For American men, elegance gave the first significant influences on clothing color preference, and the next came sociability and neatness, while elegance was the first and the next came sociability and attractiveness for American women.

The purpose of this paper is to understand the ethnic characteristics of official uniforms of Qing(淸)) by comparing the rank systems of official uniforms of Ming(명(明)) and Qing(淸)) dynasties. As research documents, Dai-Ming-Huidian(大明會典)) and Qing-Huidian-Tu(淸明會圖)) have been used. This research shows that there are many traditional characteristics of Manchurians (滿族)) in the official uniforms of Qing(淸)) dynasty. The characteristics are as follows: First, Qing dynasty made their own official uniform based on the traditional Manchurians(滿族)) costume, and added rank system on it. Second, Qing dynasty used the animal's leather as the material of official uniforms and distinguished the level of the uniforms according to the rerity value of rareness, color, and warmth of the leather. Third, Qing dynasty used pearls produced in Manchuria as the highest level, as opposed to jades and rhinoceros horns of Ming. Fourth, Qing dynasty eliminated the animal's rank system of twelve patterns which had been used for whole history of China, but the Emperor is the only man who is able to use twelve patterns. Qing dynasty made her own pattern system of standstill/moving dragons and standstill/moving pythons. Fifth, Qing dynasty used the rank system by colors in the order of yellow, red, and blue consistently over various official uniforms, while Ming used different color orders for different uniforms.

In this study, when we reflect the preference of consumers who wish to receive their health through natural materials, and whose purpose is to receive good quality and good tasting cookies made from ginger. After 0%, 2%, 4%, 6%, 8% of flour was replaced by ginger powder for making cookies, a comparative analysis of quality characteristics and QDA was completed. Adding ginger powder caused a decrease in the density of the cookie dough, moisture content, loss rate and leavening rate of cookie (p<0.05), but the hardness of the ginger cookie increased. As a result of the description analysis of adding ginger powder, adding ginger powder increases, cookie color, crispiness, acid taste, flavor, and an after taste, but not the sweetness of the cookie. In terms of cookie color, crispiness, taste, flavor and overall acceptability, adding 4% ginger powder received high reviews. Also as a result of measuring DPPH radical elimination, ginger powder shows to have good antioxidant activity. So their anti-cancer activity is better than cookies without ginger powder. Therefore, we expect that we can fulfill the overall acceptability.
