  • To obtain various colors from the blue emitting poly(fluorene)s, two different approaches are introduced. One is copolymerization with low band gap comonomers and the other is molecular doping with various dyes. As fast and efficient exciton migration and trapping and/or energy transfer between the chromorphoric segments or doped dyes in conjugated polymers can shift the emission to longer wavelengths, these phenomena can be utilized to obtain various colors from the intrinsically blue light emitting poly(fluorene)s.

  • The Automated Eichner Iris Photometer(AEIP) at the Korea Basic Science Center was tested for its function and the proper procedure for photographic photometry. The AEIP requires about three hours for reaching the electrical stability. When the iris is controlled automatically, the repeatability of density unit (DU) is accurate in the uncertainty of ($0.0028{\sim}0.0048$)DU. The iris reading is found to be accurate within the mean error of $0.^{m}05$, which could be reduced to $0.^{m}02$ by the manual control. To check the applicability of the AEIP. each two photographic plates for UBV colors which were taken by Dupuy and Zukauskas(l976) for the open cluster Byur 2, were measured by using the AEIP. and the photographic magnitudes and colors of the stars in Byur 2 were determined. discussing the previous results.

  • In this study, the characteristics of the 2-wavelength white organic light-emitting diod (WOLED) with two colors of yellow and blue were compared and analyzed with 3-wavelength WOLED with three colors of red, green, and blue. The results indicated that the power efficiency of the 2-wavelength WOLED was 1.6 times higher than 3-wavelength WOLED. In addition, the colot coordinate of the 2-wavelenth WOLED which was (0.34, 0.39) was found closer to the optimal color coordinate for the white-lighting application when compared with that of the 3-wavelength WOLED.

  • This survey paper aims to compare two significant figures in the history of Haute Couture e.g, Paul Poiret and Coco Chanel, who played a leading role between 1910 and 1930. It is found here that they have common features with respect to giving freedom to body through costume, enlarging Garconne Mode, creating more value of Costume Jewelry, exploiting advertisement strategy using models, proving exotic styles, and last but not the least contributing to Haute Couture. The research shows, however, that Poiret differs from Chanel in that he made most of various natural colors whereas Chanel used black or beige colors that had been rarely used woman wear previously. They also differed in using fabric, permitting copy by others, ingredients and bottling of perfume, meaning of silhouette. This kind of comparative research is expected to provide more understanding of fashion history and to contribute to more rigorous analysis of key success factors of designers in his or her age of fashion.

  • Proofing is one of the inspection operations of printing and can be considered a process control step. The three main kinds of proofs are press proofs, photomechanical proofs, and digital proofs. Photomechanical and digital proofs are also generally refered to as "off-press" proofs. Off-press color proofs are more economical than press proofs. Digital proofs offer fast production time along with a much lower cost per page. Hard-copy digital proofs can be output using thermal transfer printers, ink jet printers, and color laser copiers, as well as dye sublimation and electrophotographic technology. Ink jet method is commonly using because of the reasonal price. But ink jet system is difficult to reproduce an exact color proof. This research was carried out for the purpose of optimization of ink jet color proofing, using two kinds of ink jet printers with 6 colors (C, M, Y, K, mC, mM) and 4 colors (C, M, Y, K) system.

  • As various colors are used indoors and such colors influence on the image of indoors, color selection and color combination are a very important issue in inferior design. The purpose of this study is to analyse characteristic of color usage in interior design elements such as the floor, the wall, the ceiling and furnitures. The result of analysis shows the frequently used Munsell code corresponding to the cmyk code. Based on this analysis, this paper classifies largely into two kinds of the color combination type which can be used leer efficient color selection with good harmony The first combination type is divided into five types and the second is classified into three types. This paper argues that combination design principle, as a strong design tool, for color should be further developed for good quality of color design.

  • Human exists in environment. As environment affects in human movement, human reacts to everything happens in environment especially by the view point of visual continuity and changeability. This study has two purposes. The one is to clarify the visual changeability due to the Human movement from the visual point based on checking the visual field. And the other is to understand the applicable possibility of Philip Thiel's method through the experiment in passing ways. Condition of this study is that colors and figures are affective elements of visual environmental sequence by the Human movement. The Human movement is due to the visual phenomenon. That means it is not limited in Philip Theil's method(Node, District). In particular, the chroma which is checked by the BPA(Basic-Pattern-Area) is the most affective visual environmental element in contemporary shopping mall. Also, everything in visual environment and the movement is connected by the time axis. As an analytical method, the sequence notation devised by Philip Thiel was applied.

  • The purpose of this study is to analyze Kapa, the traditional bark cloth of Hawaii, including materials, method of manufacture, and colors and patterns, and to show the characteristics of Kapa to identify traditional culture of Hawaii as well as the unique culture of cloth of Hawaii in tropical area. The method of study is qualitative research using documentary records about Kapa. The cultivated Wauke proved to be the best material for bark cloth in Hawaii. The manufacture of Kapa was made by beating divided into two stages. The dyes for coloring were very different due to the existence of various plants. Indigenous Hawaiians showed the unique textures like grooving and watermarks, and the various designs in their Kapa. The characteristics of Hawaiian Kapa appear the symbol of some colors, the preference of geometrical patterns, the various uses of Kapa, and perfumed Kapa. Through these characteristics of Hawaiian Kapa, the traditional culture of indigenous Hawaiian can be understood very well. This study will help people understand indigenous bark cloth of tropical areas including Hawaii.

  • Usual1y, common color systems have been expressed with two dimensional method such as books. We think that the three dimensional presentation of color is very useful to know the characteristics of the color palette for interior design. And, it might be convenient far planning the colors of interior design. This paper deals with the method of 3D presentation. We used AutoCAD 2000 and 3dMax 4.0 in modeling the color system. By presenting which parts of the munsell color system used in the colors which have appeared in interior design three dimensionally, the guideline fur the interior designers can be suggested.

  • In this study, we propose the new color-based image retrieval technique using the representative colors of images and their ratios to a total image size obtained through color segmentation in HSV color space. Color information of an image is described by reconstructing the color histogram of an image through Gaussian modelling to its representative colors and ratios. And the similarity between two images is measured by histogram intersection. The proposed method is compared with the existing methods by performing retrieval experiments for various 1280 trademark image database.
