This study is aimed to a textile design with a motif of korean endemic plants and a method for printing it in an eco-friendly manner. The floral pattern with the motif of korean endemic plants was designed using Illustrator and Photoshop program. CMYK color, which is the basic color of Digital Textile Printing (DTP), is based on natural dyes, and various colors, achromatic colors and pastel tones are applied. As a result, half-linen and cotton were suitable as a result of designing and applying a floral pattern of a korean special plants. Also, as a result of analyzing the printing effect by colorway and DTP for each material, it was printed uniformly and the washing fastness was good. However, fastness of color change showed low, indicating that a follow-up study was needed. This study contributes to environmental conservation through eco-friendly printing and the korean endemic plants will be interested in people around the world beyond korea.

This study examines the Korean traditional and characteristic coloring through the color of Korean traditional embroidery. This research gives the chance to establish the cultural identity of Korea and presents the aesthetic standard of color images. Also, practical use of Korean traditional colors through this study provide opportunities which develope cultural merchandise in the world. were chosen as the references to analyzed the Korean traditional colors through gungsu: court embroidery, buddhist embroidery, everyday embroidery and clothing embroidery. Because this book published in commemoration of '20th General Conference and 21th General Assembly of ICOM' in 2004, which presented excellence of Asian culture. The color of these works were divided by 'Pantone Solid Color Chips' which organized by CMYK color system and categorized by Obangsaek. 'Gungsu' had vivid and splendid color sense which used strong and bright colors and 'buddhist embroidery' had mild and mysterious feelings which used low saturation.'Everyday embroidery' used the red color group frequently and 'clothing embroidery' had brighter colors comparing to other embroidery groups. The 'Chung(blue)' group had diverse color tone rather than one-tone color. This means that Koreans prefer the 'Chung' and used it regularly, also this color symbolized the racial characteristics. Even though 'Whang(yellow)' was prohibited because the color for emperor, in the case of embroidery, there were a variety of yellow colors from 'gold' to pale yellow and grayish yellow. The arrangement of colors in 'gungsu', tone on tone, complementary and bicolore coloring was used mostly which presented a strong and elegant color sense. On the other side, 'buddhist embroidery' used tonal coloring which gave gentle and noble feeling. 'Everyday embroidery' presented separation and accented coloring which was the example of common people's humor and originality. In the case of 'clothing embroidery', there was dominant lightness, separation, tone on tone and camaieu coloring which added gorgeousness in Korean traditional clothing.

This study aims to be the useful resources for selecting play therapy facility in the future by analysis of used colors in the play therapy facility as the subsequent studies of the thesis of KIID in 2010, titled 'Study on the planning factors of case study for children's play therapy center'. As research method of this study, the overall understanding about play therapy facility was improved through theoretical considerations, and it was about the Moon-Spencer's theory of color harmony which will be used for the framework of case study. In Section 3, the field trips at 6 facilities were conducted as the case research and the data research through website was conducted for case study. Moon-Spencer's theory of color harmony used the Munsell's color Order System, so after measuring CMYK value of the picture for the case research through photo shop, the color, brightness and saturation were measured through Munsell Conversion program. The following three kinds of features were drawn by research of the harmony and disharmony of used colors for the cases after substituting the theory of color harmony through the measured color. brightness, and saturation. First. series Y and YR were used mainly for warm image as the concept of play therapy room. Second, the various colors were used for comfortable image like home. But the various patterns were used by mixing for the therapy room F, so it gives confusing impression. Third, series YR and achromatic color as the color of wood were used unavoidably for using materials of manufactured goods.

For the color offset printing, it starts with input of data. The past days, drum scanner or flat scanner used to input of data, but now it changes gradually into using of digital camera because digital camera become popular. The high quality digital camera saves as a data(RAW format), sRGB which have built in digital camera, or Adobe RGB format. sRGB of ICC(International Color Consortium) profile is a standard color gamut of digital camera. Distribution of color gamut in sRGB is less than Adobe RGB have a distribution in ICC profile. sRGB also can not be expressed in some specific part, because distribution of color gamut in sRGB is not able to cover all parts in ICC Profile of international standards CMYK. It is more popular to use Adobe RGB than sRGB to do high quality offset printing and software basis color setting in Europe and Japan. In spite of this data basis, there is a difficulty of doing color correction between the color proofing prints and the final prints. To see how the software color setting effects to RGB data, this thesis will use Gretag Macbeth ColorChecker 24 patch which has the most general natural color chart to compare sRGB and Adobe RGB to check the differences of color changes. It will use the several factors that came out from the process of making ICC Profile to figure out the optimum In-house profile. It also compares the differences of using matt paper and glossy paper to do best quality color proof offset printing, and how the Rendering Intent effects the proof print.

This study intends to find out possible variations in physical properties and color of hair depending on dye type(acidic and alkalic) and permanent treatment/hair dyeing procedure. To meet the goals, healthy hair samples were taken from 5 women's hair speciment in 20's without experiencing in any harmful substance via long-term medications. and beauty care using chemicals. To get possible findings depending upon hair dye type and treatment procedure, both acidic and alkalic hair dye were applied on some specimens after permanent treatment, while on other specimens before permanent treatment. In order to determine scale damage, this study used SEM(Hitachi S-2500C) both hair thickness and tensile strength were measured with optical microscope(Nikon, MM-60/L3T) and Instron (4482-standard). Wave configuration was measured transverse and longitudinal round diameter. The chromaticity of each specimen was measured using a spectrocolorimeter(Color Techno System, JP/JX-777) with visual $C/2^{\circ}$ (at $2^{\circ}$ with C light source) monitor fixed to determine Lab and CMYK values. As a result, it was found that hair specimens were more significantly damaged with alkalic hair dye treatment than with acidic hair dye treatment, while hair specimens were more effectively dyed with the former hair dye type than with the latter one. For possible results depending on treatment procedure, it was found that hair specimens were less damaged but more effectively dyed with permanent treatment followed by hair dyeing than vice versa. Therefore, it was concluded that permanent treatment followed by acidic hair dyeing would be more effective in reducing hair damages.

Clouds in the atmosphere are important variables that affect the temperature change by reflecting the radiant energy of the earth surface as well as changing the amount of sunshine by reflecting the sun's radiation energy. Especially, the amount of sunshine on the surface is very important It is essential information. Therefore, eye-observations of the sky on the surface of the earth have been enhanced by satellite photographs or relatively narrowed observation equipments. Therefore, cloud automatic observing systems have been developed in order to replace the human observers, but depending on the seasons, the reliability of observations is not high enough to be applied in the field due to pollutants or fog in the atmosphere. Therefore, we have developed a cloud observation algorithm that is robust against smog and fog. It is based on the calculation of the degree of aerosol from the all-sky image, and is added to the developed cloud reader to develop season- and climate-insensitive algorithms to improve reliability. The result compared to existing cloud readers and the result of cloud cover is improved.
