The purpose of this study was to investigate the effect of hairstyle, hair length, and hair color on women's professional image. The quasi-experimental method by a $2{\times}3{\times}3\;(hairstyle\;{\times}\;hair length\;{\times}\;hair color)$ factorial design was used. Subjects were 343 women in Seoul, Korea. The bright brown hair was perceived to be less professional than the black and the dark brown. The straight hair was evaluated to be more professional than the wavy hair in the short and the medium length hair, whereas the wavy conveyed a higher professionalism than the straight style in long hair. The shorter the hair was, the more professional the image was. Among 18 stimuli, the short straight hair in black was evaluated to have the highest in professional image, and the long straight hair in bright brown was the lowest. Perceivers in their 40's and 50's evaluated the bright brown hair to be more professional than those in their 10's to 30's did. The present findings provide that hairstyle, hair length, and hair color are significant cues when perceiving women's professional image.

In this paper, we propose a traffic light detection and recognition (TLDR) algorithm in the daytime. The proposed algorithm utilizes the color and shape information for the TLDR. At first, a traffic light is detected and recognized based on its shape information. Then, the color range of the detected traffic light is investigated in HSV color space. The input data of the proposed TLDR algorithm is the color image captured using the black box camera during driving. Our simulations demonstrate that the proposed algorithm can achieve a high detection and recognition performance for the images including traffic lights.

Black jujube was made by aging dried jujube and its physiochemical characteristics, antioxidant activities and ${\alpha}$-glucosidase inhibitory activities were evaluated. The moisture and sugar contents were increased depending on the period of aging times and the pH was reduced thereby increasing acidity. The color of black jujube extract was changed from red to black resulting in decreases of Hunter color values L, a and b. As the aging progressed, sucrose was decomposed by increasing glucose and fructose, indicating higher contents of the total reducing sugars. Among the six different types of organic acids extracted from dried jujube, the levels of oxalic acid and citric acid were increased as the aging progressed. The total polyphenol contents in ethanol and water extracts of dried jujube were 7.74 and 8.12 mg/g, respectively. The water extract of black jujube aged for 48 hr contained the highest polyphenol contents at 16.82 mg/g. The 5'-hydroxymethylfurfural (5'-HMF) contents of black jujube extract significantly increased by longer aging times, and contained higher contents in the ethanol extract than water extract. The ethanol extract of black jujube showed the highest 5'-HMF content with 338.89 mg% after aging for 3 days. Also, $IC_{50}$ values of black jujube aged for 72 hr evaluated by DPPH and ABTS radical assays were 0.54 and 0.59 mg/mL, respectively. ${\alpha}$-Glucosidase inhibitory activities of black jujube at the concentration of 3.33 mg/mL (ethanol extract) increased from 65 to 80 % after aging for 72 hr.

To develop functional bread and improve the quality of gluten-free bread, this study investigates the quality characteristics of gluten-free rice bread made from soft-type rice (Bodeurami) flour mixed with black rice at different levels (0%, 10%, 20%, 30%, and 40%, w/w). An increase in the mix level of black-rice flour increased the weight of rice bread but reduced its volume, baking loss, volume expansion, and specific volume. The results for Hunter's color value and texture measurements indicate that an increase in the content of black-rice flour reduced the L-value, the b-value, hardness, gumminess, and chewiness but increased the a-value, adhesiveness, and springiness. According to the sensory analysis, rice bread formulated with a mixture of soft-type rice flour (80%) and black-rice flour (20%) showed the highest scores in color, taste, texture, and overall preferences. With respect to flavor and appearance, bread samples with 20% and 30% black-rice flour were preferred to those with 0%, 10%, and 40% black-rice flour. These results suggest that gluten-free rice bread mixed with wet-milling rice flour and black-rice flour can be used to develop functional and gluten-free bread.

This study researched the symbolic meaning of the costume colors in the independent film . The purpose of the study is to shed light on the relation between a film and the clothing color by exploring the symbolic meaning of costume colors as based on place images and as reflected in characters' internal psychological states and situations. The conclusions of this study are as follows. First, the colors primarily presented were neutral shades of black and white or dark, almost-black tones, representing the negative narrative structure and depicting the image of a human being. Second, a series of bright blue shades were presented to reflect the positive narrative structure of a human being returning successfully to reality. Third, the application of color, involving both the psychological aspect as well as the symbolism of color, was effectively delivered to the audience. Fourth, the emphasis on color in the smallest details of costumes was analyzed, and it was found that symbolic color effectively communicated the whole image of transformation as the story progressed, clearly delivered delicate emotional messages, and contained symbolism relating to particular places and situations.

The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

Powders prepared from three different varieties of Korean ginseng (white, red and black) are consumed daily by many Koreans as a functional food material. These variants exert a variety of physiological effects. The principal objective of this study was to evaluate the quality characteristics of Yanggaeng prepared with three different types of ginseng powder. We conducted tests for ginsenosides content, Hunter's color values, mechanical characteristics, and sensory evaluation analysis. The ginsenosides of black ginseng were higher than those of white and red ginseng. The lightness of the black ginseng Yanggaeng was significantly less than the white, red, and control samples (p<0.05). We noted significant differences in Hunter's a and b values. With regard to the mechanical properties of the samples, we noted significant differences in gumminess (p<0.05), but no differences in hardness, springiness, chewiness, and cohesiveness were detected. The results of sensory evaluation showed that there were significant differences in the color, flavor, and overall quality of the samples (p<0.05), but there were no significant differences in taste and texture. Overall, red ginseng Yanggaeng appeared to have the most commercial value for improving the Yanggaeng product.

The purpose of this research was the comparative study of 3 kinds of black soybean on murine immune cells. The 3 kinds of black soybean are Glycine max Merr. with inner color-yellow (GY), Glycine max Merr. with inner color-greenish (GG) and Rhynchosia volubilis Lour. (RV). All of the black soybean increased the viability of murine thymocytes in vitro. The combined treatment of GY or GG and mitogen did not affect the viability of splenic T- and B-lymphocytes compared with mitogen-treated group, but the combined treatment of RV and mitogen increased their action compared with mitogen-treated group. Also, the 3 kinds of black soybean were given p.o. once a day for 7 days, respectively. RV increased the population of thymic-$CD8^+$, splenic-$CD8^+$ and $B220^+$ cells in vivo. Furthermore, GY and GG did not affect the phagocytic activity and the production of nitric oxide in peritoneal macrophages in vitro, but RV enhanced their action. These results suggest that immunopotentiative action of Rhynchosia volubilis Lour. is more potent than their of Glycine max Merr.
