  • Human's sight holds the most extents for recognizing information among other senses. If we make much better visualized environment for human, it will become more beneficial in person's emotion or body. Human is using a lot of display units in modern society. Basic hues ate Red, Green and Blue. Using these three colors, we can change hue sense and degree of brightness of display unit. If we control hue of unit to be suitable according to individual environment, we can feel comfortable or reduce stress. In this paper, we present Human-Friendly Intelligent Hue Control System(HFIHCS) that control hue of display unit using fuzzified factors related to human's emotion and environment. The effectiveness of the proposed system is demonstrated by questionnaire.

  • The purpose of this study is to identify the effect of four clothing cues(hue, tone, skirt width, and skirt length of dress) on female impressions. The experimental materials developed for this study are a set of stimuli and response scales. The Stimuli are 40 color pictures manipulated with four clothing cues by drawing. The 7-point scale designed for visual evaluation of female impression formation includes 29 bipolar adjectives. The subjects were 240 undergraduate female students in Jinju city. The results of this study are as follow: As analyzing the impression of the female figure by the hue, tone, skirt width, and length, five factors including ability activity, elegance, attractiveness, concentration of attention, and tenderness were identified. Among these factors, ability activity and elegance were proved to be more important. Each impression of hue and tone with skirt width length have significant effects on concentration of attention, and tenderness. We can express various impressions by diversifying hue and tone. Each impression of skirt width length with hue and tone have significant effects on ability activity and elegance.

  • Four Trichoderma strains (CH2, SH16, PQ34, and TN42) were isolated from soil samples collected from Quang Tri and Thua Thien Hue provinces in Vietnam. The strains exhibited high chitinolytic secretion. Strain PQ34 formed the largest zone of chitinase-mediated clearance (> 4 cm in diameter) in agar containing 1% (w/v) colloidal chitin. Analysis of the internal transcribed spacer regions of these strains indicated that they were Trichoderma asperellum. The molecular weights of the chitinases were approximately 42 kDa. Chitinase genes (chi42) of T. asperellum strains TN42, CH2, SH16, and PQ34 were 98~99% homologous to the ech42 gene of T. harzianum CB-Pin-01 (accession No. DQ166036). The deduced amino acid sequences of both T. asperellum strains SH16 and TN42 shared 100% similarity.

  • In the preliminary experiment, the factors(soil moisture content, type of organic fertilizers, wound of ginseng, and concentration of rusty-root causing bacteria) inducing the rusty-root of ginseng were investigated. The Hue values were measured for the degree of rustiness affected by the factors. The rustiness was severe on the wounded-ginseng and on the ginseng inoculated with Agrobacterium tumefaciens (CG20126). The Hue values of the control, the non-wounded ginseng inoculated with CG20126, the wounded-ginseng, and the wounded-ginseng inoculated with CG20126 were 113.3, 108.1, 85.8, and 57.5, respectively. The Hue value of the horticulture bed-soil was 56.8 whereas the value of the paddy bed-soil counterpart was 64.7. The Hue values on the ginseng roots grown in the soil containing 10%, 20%, 50%, and 70% of moisture, were 96.2, 85.9, 78.0, and 75.7, respectively. The organic fertilizer increased the rustiness of ginseng and the range of Hue values was 35.2-27.8. The increased concentrations of A. tumefaciens CG20126 increased the rustiness of ginseng. The concentration of A. tumefaciens CG20126 at $10^{2},\;10^{4},\;10^{6},\;and\;10^{8}cells/m{\ell}$ resulted in the Hue values of 62.8, 63.3, 55.6, and 48.8, respectively.

  • The Hahn double 15 hue test is used for social and vacational aptitude test to separate strongly and mildly affected subjects among the colour vision defective persons, detected using colour vision test. However, the assessment of colour vision defect type and severity is based on the hue confusions which are represented diagrammatically on Hahn double 15 hue score sheet, this qualitative assessment of the test results have not provide a numerical score suitable for methematical analysis. This paper presented a new proposal for quantitatively scoring the Hahn double 15 hue test based on those hue confusions made by the subject. With this program large numbers of double 15 hue test results can be processed easily and rapidly, and program helps to compare the severity of specific type colour vision defect and monitor acquired colour vision defect which has various disease process, continuously.

  • The aim of this study is to evaluate the effect of yeast extract (YE) and salicylic acid (SA) on the expression of curcuminoid-biosynthesis genes (CzDCS and CURS1-3), and accumulation of curcumin in Curcuma zedoaria cell cultures. The results showed that, in cells treated with YE or SA, the expression levels of curcuminoid genes were 1.14- to 3.64-fold higher than the control (untreated cells), in which the YE exhibited a stronger effect in comparison with SA. Curcumin accumulation also tended to be similar to gene expression, curcumin contents in YE- or SA-treated cells were 1.61- to 2.53-fold higher than the control. The SA treatment at the fifth day of culture stimulated the curcumin accumulation and expression in all four genes compared to that at the beginning. While the YE treatments gave different results, the CzCURS1 and CzCURS3 genes were expressed strongly in cells that were treated at the beginning. However, the CzDCS and CzCURS2 genes showed the opposite expression pattern, they were activated strongly in the treatments at day five of the culture. However, the content of curcumin reached its maximum value on the fifth day of culture in all investigations.

  • Hand segmentation and tracking is essential to the development of a hand gesture recognition system. This research features segementation and tracking of hand regions based the hue component of color. We propose a method that employs HSI color model, and segments and tracks hand regions using the hue component of color alone. In order to track the segmented hand regions, we only apply Kalman filter to a region of interest represented by a rectangle region. Initial experimental results show that the system accurately segments and tracks hand regions although it only uses the hue compoent of color. The system yields near real time throghput of 8 frames per second on a Pentium II 233MHz PC.

  • This paper proposes a new algorithm classifing same hues in order toe estimate the spectral reflectance of object from 3 band color image information. To estimate the spectral reflectance of object, the conventional estimation methods are required of 5 or 9 band digital color values. The 5 or 9 band image acquisition systems are required of 5 or 3 times same work for color image acquisition process. To solve the above problems, we propose a new method that can be estimated spectra reflectance estimation of object. The proposed method is to classify same hues corresponding a color stimulus, by using hue angle and chroma vector of a color stimulus. The classified same hues are used as the population corresponding a color stimulus. The range of same hue is estimated by the cumulative proportional ration according to the number of basis function.

  • The purpose of this study is to investigate the efficiency of systematic color combination for apparel and textile design. We planned the new color systems, HUE AND TONE COLOR SYSTEM 277 and HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS. In order to emprove the efficiency, this study aims to explore the development of systematic color combination by computer graphics. With this purpose, this study progressed in the following order and we obtained these results. 1. First, we considered the possibility of the development of the systematic color combination used the new color system, HUE AND TONE COLOR SYSTEM 277. We considered the possibility of the development of the systematic color combination by graphic computer SDS-480. Through the experimental regulation of the RGB (Red, Green, Blue) and HLS (Hue, Lightness, Saturation) we obtained an approximation of the colors of the HUE AND TONE COLOR SYSTEM 277 on the CRT display of SDS-480. 2. We planned the new color system, HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS for systematic color combination. 3. In a practical application, we tried five principal types of color combination in apparel and textile design, monochromatic combination, tone on tone combination, moderate combination, tonal combination, and contrast combination. 4. Furthermore, we applied the systematic color combination for the textile patterns by tone on tone combination. By using the systematic color combination for apparel and textile design, we realized the efficiency and utility of the systematic color combination.
