  • We report experimental and simulation results of L0 state using inner retarder film compared with normal retardation film. In short wavelength range, the reflectance of inner retardation film is three times compared with that of normal retardation film. This results in blue color of L0 state, as retardation decreases or polar angle increases, the color shifts toward purple, finally yellow color, as expected in the simulation results.

  • The purpose of this study was to investigate 1) color concept development in preschool children, 2) general color preferences using colored parers, 3) specific color preference using colored chairs, and 4) to determine the relationships of sex and age to general color preference. The present experiment with materials developed through the pilot experiment, was conducted with 70 3, 4, and 5-year-old children attending the Child development research institute of Yonsei Univ. as subjects. Data were analyzed with SAS package using frequency, percentage, $\chi$\sup 2\-test, C\sup 2\ and visualized by SAS graph with tektronix 4113.

  • Achieving white balance is one of the key issues for LCD image quality enhancement. A well-known color correction algorithm is Accurate Color Capture (ACC). Determination of ACC correction values has been time consuming as past methods have required trial-and-error analysis of differences between predicted and measured values. We propose a new ACC value determination method that uses spatially emulated patterns and measured values on patterns.

  • As an essential factor of plasticity in fashion, color reflects socio-cultural trends and has possessed different symbolism in its historical development. This study aims to search for an academic approach towards finding out how the concepts and symbolism of the color white were expressed in actual clothing. This will be realized through the investigation of the various meanings this particular color possesses. The secondary purpose of this study is to give shape to the results of above said academic investigation by proposing their integration into actual fashion design. The methodology employed in this study and results are as follows. First, the symbolism of the color white abstracted from the research of literature on this subject was classified into six categories; purity, grace, abstinence, sublimity, decorativeness, and avant-garde. Second, for empirical research, six designs were developed and produced into white dresses. The development of these dress designs was realized by presenting the symbolism of the aforementioned six categories into images, and the formative constructions of these images by applying various design details, expressive techniques, and characteristics of the materials. Through an investigation into the color white, which has been excluded from previous chromatics research as a major color, integration of the symbolism and chromatic image of this color into the actual fashion design process is made possible. The significance of this study is in that it proposes multifarious possibilities in fashion design, and also in extending the horizon of chromatics research in fashion through the realization of the above process.

  • We achieved a highly efficient green OLED with an efficiency of 30cd/A by using a new electron transport material and optimizing the device structure. The luminous efficiency was 16.8lm/W at $3000cd/m^2$ and the lifetime was over 60,000hr at an initial luminance of $1000cd/m^2$. Furthermore, we obtained a threecomponent RGB white OLED by using the highly efficient green material. This RGB white OLED shows more excellent color reproducibility for full color displays with color filters, compared to a twocomponent white OLED.

  • The purpose of this paper is to propose ways to remove false color noise (FCN) generated during de-mosaicing on RGB Bayer pattern images. In case of images sensors adapting Bayer pattern color filters array (CFA), de-mosaicing is conducted to recover the RGB color data in single pixels. Here, FCN phenomena would occur where there is clearer silhouette or contrast of colors. The FCN phenomena found during de-mosaicking process appears locally in the edges inside the image and the proposed method of eliminating this is to convert RGB color space to YCbCr space to conduct smoothing process. Moreover, for edges where different colors come together, censoring based smoothing technique is proposed as a way to minimize color blurring effect.

  • In this paper, magenta coupler was prepared by the reaction of 1-(2,4,6-Trichlorophenyl)-3-(5-amino-2-chloroanilino)-5-pyrazolone with 2,4-di-tert-pentyl-phenoxy butanoyl chloride in the presence of pyridine. The product was identified by using various analytical tools such as melting point, elemental analyzer, IR spectrophotometer, UV-Vis spectrophotometer and GC-mass spectrometer. The reaction of magenta coupler with CD-3 (color development agent) was shown magenta color.

  • The effects of various packaging systems, vacuum packaging (VACP), medium oxygen-modified atmosphere packaging (50% $O_2/20%$ $CO_2/30%$ $N_2$, MOMAP), MOMAP combined with vacuum skin packaging (VSP-MOMAP), high oxygen-MAP (80% $O_2/20%$ $CO_2/30%$ $N_2$, HOMAP), and HOMAP combined with VSP (VSP-HOMAP), on the activity of antioxidant enzyme, and oxidation and color stabilities in sliced Hanwoo (Korean cattle) beef loin were investigated at $4^{\circ}C$ for 14 d. Higher (p<0.05) superoxide dismutase activity and total reducing ability were maintained in VSP-MOMAP beef than in HOMAP beef. Lipid oxidation (2-thiobarbituric acid reactive substances, TBARS) was significantly (p<0.05) retarded in MOMAP, VSP-MOMAP, and VSP-HOMAP beef compared with HOMAP beef. Production of nonheme iron content was lower (p<0.05) in VSP-MOMAP beef than in HOMAP beef. Red color ($a^*$) was kept higher (p<0.05) in VSP-MOMAP beef compared with MOMAP, HOMAP, and VSP-HOMAP beef. However, VACP beef was found to have the most positive effects on the antioxidant activity, oxidation and red color stabilities among the various packaged beef. These findings suggested that VSP-MOMAP was second to VACP in improving oxidation and color stabilities in sliced beef loin during chill storage.

  • The term color management system design, an ensemble of algorithm that provides a framework in which color information can be processed consistently throughout a digital imaging system. This is most commonly achieved through the use of special color transformation, known as device independent color transformation based on ICC device profiles. The purpose of this paper is to present some of the scientific principles of color management, and the original color management algorithms and solutions for digital soft color proofing system development.

  • For the development of 100[W] stage lighting, quantitative and uniform color mixing that applied through color adopted Simple-Inverse matching so that color mixing can be possible along Black Body Locus. R,G,B(Red, Green, Blue) LED(Light Emitting Diode) arrangement through LED package character analysis, LED module, and the characteristic of device were considered for uniform color mixing. A distance changeable optical device was built to assure high uniformity and high diffusion of not only the middle of diffusion side but also the border side. Also, we developed the control power circuit that can expand up to 6 channels which are possible for quantitative color mixing, and the high uniformity and high quantified border light for color mixing control and the verification of color mixing characteristics by composing GUI(Graphical user interface) including color mixing simulator. By presenting the experimental results of light color control, we proved the usefulness of our developed border light and the proposed color mixing method.
