Objects : Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) have been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Korean Traditional Medicine. In this research, we examined the effect of the extracts, obtained from EtOH extracts of 3 kinds of traditional plants, on hair growing activity of the DP6 and C3H10T1 cell and physical properties. Materials and Methods : On the basis of previous studies, three traditional plants were selected and we extracted them with ethanol. We evaluated their hairy dermal papillar cell proliferation activity and mouse mesenchymal stem cell in vitro model. Also, 3 herbal extracts were added to the normal shampoo formulation in ranges of 0.1% and we validated tensile properties and physical changes using aged hair. In this research, we compared the tensile strength, shine and color appearance between the hair (general formulation) and the hair after applying shampoo with natural extracts. To analyze the luster and color image, we use the SAMBA hardware and software made by Bossa Nova Technologies. Results : In the comparative test for tensile characteristic between the hair treated general formulation(control) and the hair applying special formulation including 3 kinds of extracts, tensile distance and energy of the latter are larger than control on average. The shine and color appearance were also increased after using shampoo including natural extracts(shine : 10.9%, color appearance: 24.12%). We observed the enhancement of hair growth activity in the DP6 and C3H10T1 cell. Especially black bean extracts had the most powerful effect in the dermal papillar cell proliferation. Conclusion : These experiments suggest that extracts of Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) stimulate the hair growth activity and can improve physical activities of aged hair. Shampoo product, which contains 3 kinds of natural extracts, would be used for the treatment for aged hair.

Senescent effects are the gradual deterioration of function caused by biological aging. Senescent effects on color vision are not clearly understood even after considerable researches. Part of the reason is that the color vision is a complex phenomenon resulting from various factors such as organic systems, and the physical (neuro-optical) and the psychological (experiential) processes of color perception. We performed a field experiment on color perceptional differences due to aging vision. Our experiment was applied to two different groups in South Korea: an experimental group (46 subjects of over the age of 61 years) and a control group (49 subjects in their twenties). The experimental tools are comprised of (1) six gradual yellowing detector board (40%, 50%, 60%, 70%, 80%, 90%); (2) pairs of vivid-strong, vivid-deep, grayish-deep, deep-dull, and bright-light tones of Blue (B) and Purple (P) colors; (3) Red (R), Yellow (Y), Green (G), Blue (B), and Purple (P) colors of dull-tones and pale-tones; and (4) a questionnaire on the semantic differential scales of the color images and color differences. A diagnosis system of gradual yellow vision, developed by the authors for this study, was adapted to generate the color detecting boards. The results are as follows. (1) There are significant differences between the two groups in detecting colors that simulate 40% and 50% of yellow vision. (2) As to the color difference detecting ability between similar tones, the experimental group shows difficulties in pairs of vivid-strong tones and deep-dull tones of the B color. And (3), the emotional responses to the dull tone and the pale tone are not stable in the red, the yellow, blue, and purple. Thus, we empirically demonstrate the specific differences in color perception between the old and young groups.

Phosphorescent PET/liquid color films and phosphorescent PET/disperse dyes films were prepared by melt casting method using Hot press. Then, weight ratios and exhaustion percent of films were 0.7, 1.2, 1.5, 2.0, and 2.3 wt.%. The effects of L/C and D/D contents(wt.%) of films on the thermal properties, crystal structure, H(%), brightness$(mcd/mm^2)$, morphology, and tensile properties were investigated by means of DSC and WAXD, etc. It was found that the melting temperature and crystalline diffraction peaks were not changes with increasing the liquid color contents and disperse dyes exhaustion. Also, in case of using liquid color to phosphorescent PET film, the H(%) and brightness$(mcd/mm^2)$ value were superior to phos.PET/disperse dyes film. The tensile strength and the tensile modulus were decreased with increasing the contents of liquid color and exhaustion of disperse dyes in the phosphorescent PET film. Also, the elongation at break was increased with increasing the contents of liquid color and exhaustion of disperse dyes in the phosphorescent PET film.

The visual sensory information in physical environments can induce or reduce occupants' stress. In healthcare settings, positive environmental stimulations can promote patient well-being by reducing their stress: poor health environments work against a patient's health. Changing the color in a patient room is an inexpensive process and thus finding better colors for healthcare settings is a cost effective method of improving healing environments. Color may have important implications for pediatric patients, but the investigation of Korean populations has been non-existent. The purpose of this study was to investigate Korean pediatric patients' color preferences for patient room design. The color preferences from 50 Korean pediatric patients were recorded and investigated for gender effects. A simulation method was used because of its reliability and feasibility, allowing for investigating the value of color in real contexts and controlling confounding variables. The overall color preferences from Korean pediatric patients showed that they preferred blue the most and white the least. Gender differences were found in red and purple. Girls preferred red and purple more than boys. The results from this study can help healthcare providers and designers better understand appropriate colors for Korean pediatric patient populations.

Contemporary architecture is philosophy and art, and science are different that holds the architecture of human thought and behavior based on a variety of physical space. In addition, the technology is used by the new media graphics, lasers, LED, which were possible only in imagination, using tools such as the time-space of the potential for explosion. In particular, it was found in the spacial color of atypical using the nature of light. Such these architecture is space people actively experiencing a sense towards the expansion of its place. Therefore, the study purpose is to explore the Steven Holl's spacial colors to utilize the space is important to the possibility of light. He prefers the connection to the invisible world is inferred from the visible world and other space. He thoughts an idea linked to the concept watercolors which is a tool that holds to the notion of the flexibility of light and shadow. Concept watercolor is the idea space, establish space, recombinant space, and the growthy space. These have shown the no fixed spacial color cause of the combination of the different tones according to the characteristics of the mixed-color development of a concept watercolors demonstrated the spacial color of the replacement. That is to establish a parody of the works light blending spacial color.

The natural dyeing of fabrics with persimmon juice(astringent persimmon, sweet persimmon, astringent and sweet persimmon mix) was investigated. After dyeing of cotton and silk fabrics with persimmon juice, we evaluated the dyeability of persimmon juice, the observation of fabric surface with high magnification video microscope, physical properties and color fastness with the conditions of repeating times of dyeing and variables of mordants. The results obtained from this study were as follows: The fabrics dyed with astringent persimmon have shown the highest color difference, while the fabrics dyed with sweet persimmon and the fabrics dyed with astringent and sweet persimmon mix have shown similar color differences. With the increase of repeating times of dyeing, the brightness of fabric decreased. However, $a^*$ value increased gradually, so that it became dark brown color. The $a^*$ and $b^*$ values of dyed fabrics with Fe-mordant have dropped significantly, so that they have shown achromatic colors. But the fabrics treated with other mordants have shown yellowish brown colors. On the surface of the fabrics, threads were bonded together by the viscosity of persimmon juice. Regardless of the types of persimmon juice, stiffness was increased after dying, while crease resistance was decreased. The water repellency of silk fabrics were improved than cotton fabrics after dyeing with sweet persimmon juice, but in case of cotton, it hasn't changed. Washing fastness was improved with the EM(Effective Microorganism)-fermented liquid treatment, and rubbing fastness of two fabrics was better in dry condition than in wet condition.

Quality characteristics of tomatoes irradiated with light (red light of far-red light followed two days later with a red light treatment), treated with ethylene, and stored in darkness were evaluated by subjective sensory and objective physical and chemical evaluations. Overall and individual liking evaluations and sensory evaluations were made by an untrained panel of eighteen people. A rankin gof treatments for consumer (panelist) acceptability was also conducted by the panel. Physical and chemical evaluations included surface color measurement (L*, a*, and b*), mechanical puncturing (firmness), soluble solids content (SSC), titratable acidity(TA), and tomato juice pH. Sensory data showed that outside color, inside color, and flavor of tomatoes treated with red light (R) and far-red light/red light (FR/R) were scored significantly higher than those of tomatoes treated with ethylene and those kept in darkness. The L* values for tomatoes treated with R and FR/R were lower (more darkening) than those for tomatoes treated with ethylene and those stored in darkness. Tomatoes treated with FR/R had the highest A* values, followed by those irradiated with R, treated with ethylene, and kept in darkness, respectively. Sensory values for firmness were similar for tomatoes treated with R, FR/R, and ethylene. Treatments had no significantly different effects on sweetness and acidity. There were no significantly different effects between treatments for pH, SSC, TA, and SSC/TA. From observations made during the study, it was suggested that R irradiation stimulated red color development in tomatoes after it had been delayed by FR irradiation. Consumer acceptability for tomatoes with either R or FR/R treatment was significantly higher than that for tomatoes treated with ethylene or stored in darkness. panelists' overall liking scores correlated well with all sensory variables except acidity, and also correlated highly with inside color, flavor, and sweetness (P<0.001). Overall liking versus flavor had the most pronounced relationship (r=0.78, P<0.001).
