In modem society, fashion is used as a means to express oneself. Colors in fashion are regarded as one of the important design elements and play a significant role. Today men's fashion trend represents to adopt diverse silhouettes, colors and various materials. They can choose diverse color for men's fashion. Brown has been popular colors for both man and woman. It usually represents the image of warm, comfort and classic. This research analyzed Brown whose diverse uses had been observed in fashion and the characteristics of Brown the color combinations in men's fashion through men's fashion collection from 2000 to 2008. The characteristics of color combinations with Brown analyzed two color combinations for the top and bottom as follows: First, the hue characteristics of Brown two color combinations were analyzed in men's fashion. Second, the tone characteristics of Brown two color combinations were analyzed in men's fashion. Third, the characteristics of color combinations were analyzed in the Brown top and bottom according to the hues in men's fashion. The Brown color combinations were analyzed according to the 10 hues and achromatic colors. As a result, 10YR was most used in both the top and bottom in F/W and S/S. As for the Brown color combinations of the 12 tones and achromatic colors in the top and bottom, dark grayish was the most used in S/S and F/W regardless of the seasons. The Brown color combinations in men's fashion were analyzed in terms of characteristics. As a result, 10YR and 2.5Y were most used. They were also of the highest frequency in the color combinations of Brown tops and bottoms.

The purpose of this study was to analyze difference in clothing preference based on the perceived body types. The objects of this study were to prepare for the establishment of a marketing strategy and alternative plan intended for users operating in a subdivided market, after analyzing the differences in clothing preference based on the perceived body types. The respondents comprised 192 female adults, who were residents in Busan. The questionnaire was composed of three sections: style, textile, and color of clothing. Data were analyzed by frequency, factor analysis, cluster analysis, discriminate analysis, and ANOVA. Cluster analysis was employed to identify groups of respondents based on the five delineated measure items. Based on the findings, three distinct groups were formed: thin, normal, and obese. The result of this study showed statistically significant differences among the three groups in terms of style, textile, and color of clothing, as well as in terms of demographic characteristics. Marketing and management implications for effectively targeting the segments are discussed.

Since Samsung SDI and Sony started mass production of AM-OLED display for mobile/TV applications, OLED technology has emerged as leading candidate among the many technologies under development for next generation Flat panel displays. P-OLED (Polymer Organic Lighting Emitting Diode) technology, a class of OLED, is gathering momentum towards commercialization. P-OLED technology has made tremendous progress in terms of display performance (including life time, efficiency and color gamut) and in the maturity of ink jet printing process and equipment. In order to get into the mobile/TV application market successfully, P-OLED display technology must meet the following display makers' requirements: (1) P-OLED Display Performance in terms of lifetime, efficiency, and color coordinates, (2) Low Cost Manufacturing Technology such as "Solution Processable Printing Technology". P-OLED technology has already overcome many of the hurdles to mass manufacturing. In this paper, the latest developments in ink jet printing technology, including P-OLED material performance, is discussed.

LCD performance is generally evaluated in terms of luminance and color versus viewing angle. In the present paper, we show that this type of display can be favorably characterized in terms of polarization. We show that ELDIM EZContrast instrument which is routinely used for viewing angle measurements can be upgrade for measuring the polarization state of the light at each incidence and azimuth angle. More precisely, the degree of polarization of light, its ellipticity and polarization direction can be measured at each incidence angle between 0 and $88^{\circ}$ and for all the azimuth angles (from 0 to $360^{\circ}$). Important differences between the displays can be detected and related to their internal structures when luminance and color profiles are quite similar. The same setup can also be used to characterize optical components of the LCDs.

Glycolic acid(GA) is well known the most effective cosmetic ingredient on the epidermal remodeling, accelerated desquamation and inhibitory effect on melanin synthesis. The various cosmetic formulations containing GA have not been reported in terms of stability. This study was to investigate the stability of three formulations(gel, cream, and ointment). The stability of obtained formulations was tested chemical and physical characteristics including the composition stability, hot-cool cycling, the variation of pH and viscosity, and the observation of color and odor. The experimental results showed that the gel and cream containing 5% GA, both formulations have proper stability in the centrifugal test, hot-cool cycling test, viscosity, pH stability and the observation of color and odor. On the other hand, the 5% GA ointment did not have stability. We concluded that the formulations of gel and cream are more suitable than ointment to use GA ingredient for developing cosmetic in terms of stability.

In this study, we propose a novel color-image segmentation algorithm to discern the teeth region utilizing RG intensity and its relevant RGB histogram features with resolving the variations of its maximum intensity in terms of peaks and valleys. Tooth candidates in a CCD image are first extracted by applying RGB color multi-threshold levels and consequently the successive morphological image operations and a Sobel-mask edge processing are performed to resolve the teeth region and its contour.

Image retrieval is one of the most exciting and fastest growing research fields in the area of multimedia technology. As the amount of digital contents continues to grow users are experiencing increasing difficulty in finding specific images in their image libraries. This paper proposes an efficient image descriptor which uses a local color and texture in the non-overlapped block images. To evaluate the performance of the proposed method, we assessed the retrieval efficiency in terms of ANMRR with common image dataset. The experimental trials revealed that the proposed algorithm exhibited a significant improvement in ANMRR, compared to Dominant Color Descriptor and Edge Histogram Descriptor.

Dyeing properties of silk fabric with black tea colorants were investigated in terms of dye uptakes at various dyeing conditions and the effect of mordants on color change and colorfastness. Black tea colorants showed high affinity to silk and produced brown color. Two types of adsorption isotherm were obtained; Langmuir and Freundlich equilibrium at 360 nm and 460 nm, respectively. Thus, it is considered that both of ionic and hydrogen bondings are involved in silk dyeing with black tea colorants. Dye uptake increased continuously as concentration of colorants increased. Brown color was not changed with mordant type except that Fe mordant produced dark brown color. Mordanting did not influence colorfastness of dyed silk significantly. Therefore, mordanting was not necessary in dyeing silk with black tea colorants.

In this paper, we describe an effective method to enhance the color night images with spatio-temporal multi-scale retinex focused to the Intelligent Transportation System (ITS) applications such as in the single CCD based Electronic Toll Collection System (ETCS). The basic spatial retinex is known to provide color constancy while effectively removing local shades. However, it is relatively ineffective in night vision enhancement. Our proposed method, STMSR, exploits the iterative time averaging of image sequences to suppress the noise in consideration of the moving vehicles in image frame. In the STMSR method, the spatial term makes the dark images distinguishable and preserves the color information day and night while the temporal term reduces the noise effect for sharper and clearer reconstruction of the contents in each image frame. We show through representative simulations that incorporating both terms in the modeling produces the output sequential images visually more pleasing than the original dim images.

This study was investigated to establish the optimum conditions of dyeing silk fabric with Brassica campestris. This experiment was done under different dyeing conditions of dye concentration, dyeing temperature, dyeing time, dyeing repeating times, and mordants which were treated pre, syn, and post methods. The effects of dyeing conditions and mordanting were evaluated in terms of dyeaffinity(K/S value) and CIE-Lab color factors. Also, the effect of mordanting on color fastnesses was assessed. The dyeaffinity increased remarkably as dye concentration increased up to 200% owf. The dyeaffinity increased continuously with dyed temperature and reached dyeing equilibrium at $80^{\circ}C$. The maximum dyeaffinity was observed at 30minutes of dyeing time. In the relationship between the K/S value and dyeing repeating times, the K/S value became higher as repeating time was increased. The changes of surface color and colorfatness of dyes were not increased greatly on all mordanting states. The extracts of Brassica campestris produced mainly yellow color in silk fabric. The antimicrobial activity existed slightly as the ratio of 22.7%.
