  • The mechanical characteristics (texture and color) and consumer preference of Doraji Yanggengs using different pre-treatments and added levels of Doraji were presently evaluated. Three kinds of Doraji Yanggengs were made with differing amounts of Doraji powder (DPY; 30, 50, or 70 g), ground raw Doraji (GRDY; 100, 200, or 300 g), and Doraji juice (DJY; 100, 200, or 300 g). Texture characteristics (hardness, adhesiveness, springiness, chewiness, gumminess, cohesiveness) and color values (lightness, redness, yellowness) were measured three times in three experiments conducted with each formulation. Preference was measured with a nine-point hedonic scale for Yanggengs once every three experiments. Consumer preference was measured with color, flavor, taste, appearance, texture, and overall acceptability. Significant differences according to the amount of Doraji powder were evident with DPY for hardness (p<0.001), adhesiveness (p<0.05), and cohesiveness (p<0.001). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.01), and gumminess (p<0.01) of 100 g GRDY displayed higher scores than 200 g and 300 g GRDY, but displayed significantly lower scores in cohesiveness (p<0.01). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.001), gumminess (p<0.01), and cohesiveness (p<0.05) of DJY showed significant differences according to amount of Doraji juice. The highest score in a preference test among DPYs was evident for 30 g DPY. There were no significant differences in preference among GRDYs and DJYs. Color, flavor, taste, appearance, texture, and overall acceptability were significantly (p<0.01) correlated in all Yanggengs. DJY was preferred more than DPY and GRDY. Women in their forties and fifties preferred Yanggeng more when compared to women in their twenties and thirties.

  • After drawing the sensory images from the color green, the difference of sensory images and the difference of the color green according to demographic characteristics and which factors affect the preference have been analysed. The thirty six-photos of 2013 women fashion show on the STYLE.COM were used for the stimuli of green colour fashion for the questionnaire. The people surveyed were adults in their 20s to 50s. The 123 copies of the questionnaire were used for the statistical analysis of this study. Factor analysis, Cronbach's ${\alpha}$ test, t-test, ANOVA, Duncan test and Regression analysis test were carried out by SPSS 19 for the statistical analysis of collected data. The results were as follows. The sensory images of green fashion were drawn in six types. The sensory images of green fashion according to demographic characteristics showed a significant difference depending on martial status, age, monthly income and occupation. The preference of green colour fashion according to demographic characteristics showed a significant difference depending on sex, age, monthly income, occupation. The variables affecting the preference of green fashion were identified as four types, and the most affecting variable to the preference was the favorable and familiar factor. These research results will become available on selecting the target customer and making the marketing differentiation strategy when planning fashion products.

  • Although innate color preference of motile organisms may provide clues to behavioral biases, it has remained a longstanding question. In this study, we investigated innate color preference of zebrafish larvae. A cross maze with different color sleeves around each arm was used for the color preference test (R; red, G; green, B; blue, Y; yellow). The findings showed that 5 dpf zebrafish larvae preferred blue over other colors (B > R > G > Y). To study innate color recognition further, tyrosinase mutants were generated using CRISPR/Cas9 system. As a model for oculocutaneous albinism (OCA) and color vision impairment, tyrosinase mutants demonstrated diminished color sensation, indicated mainly by hypopigmentation of the retinal pigment epithelium (RPE). Due to its relative simplicity and ease, color preference screening using zebrafish larvae is suitable for high-throughput screening applications. This system may potentially be applied to the analysis of drug effects on larval behavior or the detection of sensory deficits in neurological disorder models, such as autism-related disorders, using mutant larvae generated by the CRISPR/Cas9 technique.
