The purpose of this study is to find out the effect of three clothing cues(jacket color, skirt color, and tone of Korean dress) on the image of Korean dress wearer using tone-in-tone coloration. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli are 16 color pictures manipulated with three clothing cues by drawing. The 7-point scale designed for visual evaluation of female impression formation includes 24 bipolar adjectives. The subjects were 192 undergraduate female students in Chinju city. The results of this study are as follow: As analyzing the image of female figure by the jacket color, skirt color, and tone, three factors including youth activity, attractiveness, and visibility were identified. Among these factors, youth activity and attractiveness were proved to be more important. Each dimensional image was affected by color coordination of jacket color, skirt color and tone of korean dress. Therefore, the image of Korean dress wearer could be varied by color coordination of jacket color, skirt color and tone of Korean dress.

The purpose of this study was to investigate the differences and interaction effects in impression formation according to eyeglasses, earrings, hair length, and clothing color worn by woman in Her 20s. A quasi-experimental method was used for this study. The experimental design was a $3{\times}2{\times}2{\times}4$(eyeglasses${\times}$earrings${\times}$hair length${\times}$clothing color) factorial design. The model of stimulus photographs was a woman with an oval shape face in her late twenties. She wore a tailored collared jacket with a white dress shirt. The subjects were 362 female college students. First, the women wearing glasses were found to be more potent but gave more negative impressions in terms of loveliness, politeness, and attractiveness than the women without glasses. Second, the women wearing earrings were perceived to have higher individuality, attractiveness, potency, loveliness, and elegance than the women without earrings. Third, the women with short hair were evaluated to have higher individuality, potency, and elegance, and to have lower loveliness, politeness, and attractiveness than the women with long hair. Fourth, the red clothes were perceived to have the higher individuality, loveliness, and attractiveness than the dark red or grey clothes. The light grey clothes were considered as the most elegant and the dark grey clothes were shown to have low attractiveness. Fifth, the women wearing the horn-rimmed glasses with short hair were evaluated to have high individuality. The women wearing glasses with short hair were evaluated lower in loveliness than those with long hair. The women with short hair, wearing glasses without earrings were evaluated very low in attractiveness.

The purpose of study is to survey the system of the Korean Gangsin-mu shaman costume and its formative character and to fine out the traditional follow patterns of government officials' attires and Po's meaning of it. The overall shape of variety 'Po's in modern times are similar to the traditional ones, but they differ greatly in size, detail color, and ornamental design. The sleeves have slits in the armholes, which can allow the hands to be drawn out easily. In addition, the knot buttons are used in the modern costumes. They are based on different formation skills from those of the traditional The original color of the shaman's costume is not their taste in color but symbolic, modern costumes color show the shaman's taste in color. This change mean a more accentuated visual effect than incantatory meaning. Another reason for color change is also the costume's material. A kind of constituent element uses synthetic fiber in modern times.

The purpose of this study was to examine the effect of clothing color and exposure on stereotype formation of female appearance. The subjects for the research survey were 418 male and female university students in Taejon, Korea. The measuring instruments were a self-administered questionnaire and six written scripts which described a woman wearing clothing manipulated by clothing color and exposure variables. The collected data were analyzed using content analysis, T-test, crosstabs analysis, ANOVA, and Duncan's multiple range test. The results of this study were as follows. First, three dimensions (global image, appearance inference, and appearance evaluation) emerged from the subject responses. Clothing exposure had the greatest impact upon the stereotype formation of female appearance. The woman wearing exposed clothing was rated as 'sexy', 'confident', and 'glamorous' whereas the same woman wearing unexposed clothing was rated as 'slim', 'humdrum', 'ladylike', and 'neat'. Second, the gender of the subject played a role in forming stereotypes of women's appearance. The male subjects rated the woman wearing exposed clothing as 'sexy' and 'glamorous' whereas the 1em81e subjects rated the same woman as 'slim' and 'pretty'. Third, the male subjects evaluated the woman wearing expend clothing in much more negative terms than the female subjects did, indicating that men tended to use 'modesty' to evaluate the woman whereas women tended to use 'fashion trend' in addition to 'modesty' as the important criteria when assessing women dressed in exposed clothing. Fourth, the subjects judged the woman wearing exposed clothing to be an entertainer or prostitute in her early 20s. On the other hand, the subjects judged the woman wearing unexposed clothing to be either a university student or a professional business women in her mid 20s.

The purpose of this study is to develop eco-printing method using natural dyes combined with chitosan treatment to impart various pattern effect on cotton fabric. It was examined whether tone-on-tone pattern effects could be produced by screen printing with chitosan paste and subsequently dip-dyed in natural dye bath. For polychromic colorants, fabrics were pre-mordanted and then screen printed with chitosan, while only chitosan printing treatment was applied for monochromic colorants. Color, dye uptake, washing, light and rubbing fastnesses of printed fabrics were measured in relation to the presence of chitosan printing. Pre-mordanting and chitosan printing treatment were applied to such polychromic colorants as madder, sappanwood, onion and cochineal. Also, printing pattern formation on fabrics was evaluated by differences in dye uptake and color. The results suggested that madder, onion and cochineal were effective on pattern formation. Regarding sappanwood, since dye uptake was increased only by pre-mordanting without chitosan printing treatment, there was little color difference and thus patterns were not clearly distinguished. Chitosan printing treatment tended to increase washing, light and rubbing fastnesses of dyed fabrics with polychromic colorants. Chitosan printing treatment was applied to monochromic colorants such as chlorophyll, gardenia and indigo and the effect of printing formation was examined according to the difference in dye uptake. Among monochromic dyes tried, chlorophyll was effective and chitosan printing improved washing and light fastnesses.

Meat becomes brown and rancid during storage in the refrigerator and display in the case. Color changes, metmyoglobin formation and lipid oxidation are the important problems in the transportation / distribution of meat and retail display. The freshness of meat is determined by the sense of vision and smell. Since conventional method determining lipid oxidation is time consuming and destructive (it needs to homogenize meat with reagents, filtrate, time for reaction and read optical density using spectroscopy), more rapid and nondestructive technical tools are desired. The objective of this work was to evaluate near-infrared spectroscopy as an analytical tool for determining meat color, metmyoglobin formation and lipid oxidation. in beef, pork and chicken. Semitendinosus and longissimus thoracis muscles from six beef steers, biceps femoris and longissimus thoracis muscles from twelve LWD crossbred pigs, and superficial pectoral muscles from twenty-four broilers were used. About a 5-cm diameter and 1-cm thick sample (20.0g) was cut from the muscle and placed on plastic foam, over-wrapped with PVC film, and displayed under flourescent lights at 4 degrees C. during 10 days for beef and pork or 4 days for chicken. The spectra was measured by NIR systems Model 5500 Spectrophotometer using fiber optic scan at range of 400 - 1100 nm. Data were recorded at 2 nm intervals and 10 scans / 10 sec were averaged for every sample. Data obtained were saved as log 1/Re, where Re is the reflectance energy, and then mathematically transformed to second derivatives to reduce effects of differences in particle size. $L^{*}$, $a^{*}$ and $b^{*}$, and metmyoglobin formation were determined by conventional spectrophotometer using the integrating sphere unit. 2-Thiobarbituric acid reactive substances (TBARS) were measured for lipid oxidation. A multiple linear regression was used to find the equation which would best fit the data. The number of wavelengths used in the equation was selected based on the fewer number compared to the increasing multiple correlation and Decreasing standard error. (omitted)

In this work, PEO (Plasma Electrolytic Oxidation) film formation behavior of Al6061 alloy was investigated as a function of applied current density of AC at 310 Hz in the range from $120mA/cm^2$ to $300mA/cm^2$ in 0.5 M $Na_2SiO_3$ solution. When applied current density is lower than a critical voltage of about $132mA/cm^2$, voltage reaches a steady-state values less than 120 V without generation of arcs and metallic color of the alloy surface remains. On the other hand, when applied current density exceeds about $132mA/cm^2$, voltage increases continuously with time and arcs are generated at more than 175 V, resulting in the formation of PEO films with grey colors. Two different types of arcs, large size and small number of arcs with orange color, and small size and large number of arcs with white color, were generated at the same time when the PEO film thickness exceeds about $50{\mu}m$, irrespective of applied current density. Formation efficiency of the PEO films was found to increase with increasing applied current density and the growth rate was obtained to be about $5{\mu}m/min$ at $300mA/cm^2$. It was also found that surface roughness of the PEO films with $70{\mu}m$ thickness is not dependent on the applied current density.

The purpose of this study is to investigate the effect of eyeshadow color(brown, purple), lipstick color(red, red purple, and yellow red), and lipstick tone(vivid, light, dull, and dark), clothing style(formal, casual), clothing tone(N9, N7, N4, N2) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 128 color pictures manipulated with the combination of eyeshadow color, lipstick color, lipstick tone, clothing style, and clothing tone using computer simulation. The subjects were 768 female undergraduates living in Gyeongnam-do. Image factor of the stimulus was composed of 5 different components, attractiveness, stability, cuteness, visibility, and tenderness. In the 5 image components, clothing style and clothing tone showed independent effect. In the stability, cuteness and visibility, lipstick color showed independent effect. Eyeshadow color and lipstick tone influenced independently on the attractiveness, stability and visibility. In the coordination of achromatic clothing with makeup face, attractiveness image by the coordination of lipstick tone with clothing tone, cuteness image by the coordination of lipstick tone with clothing style or clothing style with clothing tone, visibility image can be produced by the coordination of eyeshadow color with lipstick color.

Oxidative hair color is currently widely used because of its beautiful light color and good dyeability. In this study, hair color, oxidative agents, and dye intermediate were reacted. Modifier, which changes color with various hue, and alkaline agent, which opens the cuticle of hair fiber and enhances the dyeing reaction, were added. For gel formation, isocetyl alcohol was used as solvent in preparing three kinds of permanent oxidative hair color. Physiochemical study of prepared permanent oxidative hair color was done for basic information acquisition. Acid perspiration test, pH measurement both at room temperature and at high temperature, drop movement test, dyeability efficiency upon the amount of hydrogen peroxide added, and humidity fastness were studied. Shampoo fastness and light fastness of prepared permanent oxidative hair color dyed hair sample were also investigated. All three kinds of hair color prepared showed good properties overall, however, dyed hair sample became reddish upon shampoo fastness and lightfastness tests.
