This research was carried out in order to suggest useful data for planning fabrics of summer eco-friendly fashion products. For this purpose, four cellulose fabrics were dyed with natural indigo under three different dyeing conditions, then, their colorimetric properties and color sensibilities were evaluated, and their influences on color preferences were analyzed. All cellulose fabrics naturally dyed with indigo showed the characteristics of PB color tones, middle and low value, and low chroma. Color characteristics were significantly different according to fiber type and dyeing condition. The color sensibilities of the fabrics dyed with indigo were classified into three factors: sporty, classic and natural. These sensibilities showed partially significant differences according to fiber type and dyeing condition. Also, there were partially significant relationships between color characteristics and the color sensibilities of the fabrics dyed with indigo. The color preferences of the dyed fabrics with indigo were found to be influenced by the sporty and classic of color sensibility and $L^*$ of color characteristics.

Soybean powder is a readily-available food ingredient. Furthermore, saltwort powder is an herb with various physiological effects. Therefore, in this study we examined the physiochemical characteristics of soybean dasik prepared with 0, 4, 8, and 12% saltwort powder. We measured Hunter's color values, mechanical characteristics, and sensory qualities. The result of each analysis is as follows. There were not significant differences between the moisture content of the control group and the groups with saltwort powder. The ash content increased while the fat and protein content decreased as the ratio of saltwort powder increased (p<0.001). In the analysis of color differences, the L, a, and b values decreased as the ratio of saltwort powder increased (p<0.001). The hardness (p<0.001) of the groups increased as the ratio of saltwort powder increased, but adhesiveness decreased. Sensory evaluation data showed that softness, hardness, and chewiness decreased while color increased as the ratio of saltwort powder increased. Finally, aroma, sweet taste, nutty taste, and overall acceptability was shown to be best for the 4% addition group.

Purpose: The purpose of this study is to investigate the differences of dynamic visual acuity to color of optical lens. Methods: we measured dynamic visual acuity using 5 colored lenses (transparent, yellow, blue, green, brown) for 30 university students. Results: Dynamic visual acuity were highest on yellow colored lens and lowest on brown colored lens, for both of naked eyes and contact lens wearers. Conclusions: It can be concluded that optical lens color can influence on dynamic visual acuity. Selection of colour lense can enhance or decrease of dynamic visual acuity. Therefore, a selection of colour lense should be carefully decided especially for athletes who needs a good dynamic visual acuity.

This study was conducted to investigate the effects of dietary supplementation of various types of fermented red ginseng marc with red koji to laying hens on eggshell and egg yolk quality characteristics. A total of 240 Hy-line Brown laying hens (40 wk of age) were randomly allotted to 24 pens (6 replicates per treatment and 10 laying hens per replicate). Experimental diets consisted of 4 treatments containing basal diet (control), 1% fermented red ginseng marc powder with red koji, 1% fermented red ginseng marc pelleted with red koji and 1% fermented red ginseng marc coated with red koji. During the 8-wk feeding trial, there were no significant differences in eggshell strength, eggshell thickness and eggshell color among the treatments, except for eggshell strength at 4 and 8 wk and eggshell thickness at 0 wk. In addition, no differences in egg yolk color and egg yolk index were found for all treatments throughout the 8-wk feeding period, except for egg yolk color at 0 wk. Thus, using various types of fermented red ginseng marc with red koji to laying hens did not improve eggshell and egg yolk quality characteristics.

This study investigated whether there were statistical differences in the three categories of cosmetics brand preference- brand preference, gift brand preference, and preference for purchasing expensive cosmetics by the consumers' residence. For the data analysis, the types of cosmetics include basic and color, the cosmetics brands include domestic and imported cosmetics. The consumers' residence include metropolitan and non-metropolitan areas. The study collected the data from 477 surveys from adult women ranging from the age groups of 20s to 50s and above in 2011. Using SPSS Version 18.0 the data was analyzed by Frequency analysis, t-test. The study results were as follow: There were significant differences in the three patterns of cosmetics brand preference depending on the consumers' residence. The three patterns of preferences were in the similar trends. The results revealed while the non-metropolitan residents showed a higher level for the domestic brands, a lower level in the three categories of preferences for imported brands compared to their metropolitan counterparts in both types of basic and color. In contrast, compared to the non-metropolitan counterparts, the metropolitan residents showed a lower level of preferences in all of the three categories of cosmetics brand preference for domestic in both types of basic and color.

In detecting human faces in color images, additional geometric computation is often necessary for validating the face-candidate regions having various forms. In this paper, we propose a method that detects the facial features using chrominance components of color which do not affected by face occlusion and orientation. The proposed algorithm uses the property that the Cb and Cr components have consistent differences around the facial features, especially eye-area. We designed the Mean-Gray Morphology operator to emphasize the feature areas in the eye-map image which generated by basic chrominance differences. Experimental results show that this method can detect the facial features under various face candidate regions effectively.

Fog is atmospheric in which tiny drops of water vapor are suspended in the air near the ground. Its form, occurrence, etc., change according to the temperature, relative humidity, wind and geographical features of the space around it. In particular, fog tends to occur near a source of water because of temperature and relative humidity difference. These days, climate change is increasingly affecting the occurrence of fog. Therefore the purpose of this study was to investigate how fog affects materials that are part of our cultural properties through outdoor exposure tests and artificial degradation. The degradation evaluation of materials as a function of fog occurrence frequency, showed that the color of metals changed noticeably, whereas dyed silk and Dancheong showed degradation on the surface and color differences but no particular tendencies. Therefore, damage prediction by color differences as a function of fog occurrence frequency was based on metal samples, which showed constant color differences. Through a comparison of the predictive value and color difference by outdoor exposure, the accuracy and applicability of the damage prediction formula was confirmed. If a more complex damage prediction formula is created, it is expected that prediction of the degree of material damage in the field would be possible.
