This study looked into the effect of the life style of single females in 20s and 30s on beauty behavior recognition, and spss 17.0 is used for data analysis method. As for the statistical analysis method in order to validate the measurement tools, reliability verification is conducted and life style groups are sampled using K-means taking into account factor scores by life style. To find out the difference between general beauty behavior recognition and life style, descriptive statistics and One Way ANOVA were carried out, and Duncan Test was implemented for the post examination method. Multiple regression analysis was also carried out to figure out the effect of life style on beauty behavior recognition. The result is as follows. First, according to the results of reliability verification and factor analysis for the lifestyle type and the recognition of the behavior for beauty, the types of the life style of the subjects were divided into Economic Utility, Convention Conservatism, Self Development, Showy Consumption, and Appearance Oriented, and the recognition of the behavior for beauty was named as Makeup and Hair, Cosmetic Surgery, Body Care, and Skin Care. Second, as to the recognition of the behavior for beauty based upon the lifestyle, the Appearance Oriented in Showy Consumption recorded the highest. Third, the analysis of the influence of the style on the recognition of the behavior for beauty showed that the behavior recognition for Makeup and Hair and for Skin Care was affected by the life style of Self Development, Showy Consumption, and Appearance Oriented; the behavior recognition for Cosmetic Surgery was affected by the life style of Conventional Conservatism, Showy Consumption, and Appearance Oriented; and again the behavior recognition for Body Care was by that of Economical Utility and Showy Consumption.

This study analyzed the effect of aesthetic elements of characters on viewing immersion and re-watching intentions in Chinese historical dramas. For the empirical study, frequency analysis, factor analysis, reliability analysis, correlation analysis, and regression analysis were performed using SPSS 23.0 based on the questionnaire of 330 Chinese who watched the historical drama . As a result of the study, it was found that the character aesthetic elements of Chinese historical dramas with hair and costumes had a positive effect on viewing immersion and re-watching intentions. In addition, it was found that viewing immersion had a mediating effect on the relationship between aesthetic factors and re-viewing intention. It is expected that continuous character creation can be expected through various aesthetic elements such as hair and clothes to increase the value of dramas in the future.

The purpose of this study was to classify sex role identity into groups and analyze the difference of social face sensitivity and appearance management behaviors by sex role identity. Questionnaires were administered to 306 people in their twenties and thirties living in Daegu Metropolitan City and Kyoungbuk province. The data was analyzed by using frequency, factor analysis, credibility, ${\chi}^2$-test, ANOVA, Duncan-test, and t-test. The findings were as follows. Sex role identity were classified into four groups (androgyny, masculineness, feminineness, and undifferentiation). Men in androgyny group showed the highest rate of 41.3% followed by undifferentiation(24.7%), masculineness(21.3%), and feminineness(12.7%). Women in undifferentiation group showed the highest rate of 35.9% followed by feminineness(24.4%), androgyny(23.7%), and masculineness(16.0%). Social face sensitivity were composed of four factors (consciousness of being embarrassed, social formality, other consciousness, and prestige). Appearance management behaviors were composed of six factors (skin management, fashion image management, plastic surgery management, weight management, hair management, and health management). According to the result of a significant difference between social face sensitivity and appearance management behaviors by sex role identity, male showed significant difference between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, social formality, and other consciousness). Both of the male and female showed a significance of difference in consciousness of being embarrassed, and social formality. Male showed significant difference between the sub-variables of appearance management behaviors factors (fashion image management, weight management, hair management, and health management). Both of the male and female showed a significance of difference in fashion image management. Gender of twenties and thirties showed distinction between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, and prestige) and appearance management behaviors (skin management, fashion image management, plastic surgery management, weight management, and hair management).

The purpose of this study was to classify types in sense of gender role identity and to figure out the difference among sociocultural attitude, benefits of clothing pursuit, and appearance management behaviors by sense of gender role identity types. Questionnaires were administered to 455 people in their twenties and thirties living in Daegu and Kyoungbuk area. Data were analyzed by using frequency, factor analysis, credibility, $X^2$-test, ANOVA, Duncan-test, and t-test. The findings are as follows. First, Men of androgyny group showed the highest rate of 38.5% followed by undifferentiation(22.9%), masculineness(21.0%), and feminineness(17.6%). Women of undifferentiation group showed the highest rate of 33.2% followed by feminineness (25.2%), androgyny(22.0%), and masculineness(19.6%). Second, factors of sociocultural attitude were internalization and recognition. Benefits of clothing pursuit consists of the factors such as consciousness of others, personality, and vogue pursuit. Factors of appearance management behaviors were dressing, skin management, plastic surgery management, weight management, health management, and hair management. Third, the result from the difference between sociocultural attitude and benefits of clothing pursuit by sense of gender role identity types, men of androgyny and feminineness showed highest in recognition while women of androgyny showed highest in internalization and recognition. The result of the difference in benefits of clothing pursuit by sense of gender role identity shows that both men and women of androgyny group have high tendency for being conscious of others, personality pursuit, and vogue pursuit while men of undifferentiation and masculineness have low interest in dressing in relationship with others. Fourth, the examination of the difference in appearance management behavior by sense of gender role identity types found men of androgyny group managed dressing, skin, weight, health and hair most while women dress and health most. Men of undifferentiation group managed dressing and weight least, while men of masculineness health, and men of feminineness hair least.

Rhododendron schlippenbachii have been used as a medicine because of their various biological activities. In this study, R. schlippenbachii ethanol extract was evaluated for the treatment of vitiligo. The R. schlippenbachii ethanol extract did not show any cell cytotoxicity. The effect on mushroom tyrosinase and cellular tyrosinase activities were further assessed. In addition, the determination of melanin content in melanocytes was measured using both the B16 melanoma cells and C57BL/6J Ler-vit/vit mice. Finally, the existence of quercetin in R. schlippenbachii was confirmed by qualitative analysis using HPLC. The results clearly demonstrated the R. schlippenbachii extract enhanced melanogenesis and also increased tyrosinase activity in cultured melanoma cells and C57BL/6J Ler-vit/vit mice. In addition, treatment with R. schlippenbachii extract led to a higher content of melanin and eumelanin in C57BL/6J Ler-vit/vit mice hair than in control (untreated) mice, which demonstrated the therapeutic effect of hair-graying associated with vitiligo. Finally, we confirmed a notable increase in melanocytes in the skin of C57BL/6J Ler-vit/vit mice treated with R. schlippenbachii extract compared with the control. Extracts of R. schlippenbachii was shown to be potent tyrosinase and melanin synthesis activator in B16 melanoma cells. The R. schlippenbachii extract have significantly higher melanin content than the untreated control in C57BL/6J Ler-vit/vit mice hair. The results suggest that R. schlippenbachii extract might be considered as an alternative treatment for improvement of vitiligo.

The objective of this study was to investigate polymorphisms of keratin-associated protein 8.1 (KAP8.1) gene and its effect on fibre traits of Chinese Inner Mongolian Cashmere goats. The fibre traits data investigated were cashmere fibre diameter, combed cashmere weight, cashmere fibre length and guard hair length. Five hundred and forty animals were used to detect polymorphisms in the complete coding sequence of the hircine KAP8.1 gene by means of PCR-SSCP. The results identified six genotypes, AA, BB, CC, AB, AC and BC, coded for by three different alleles A, B and C. Two SNPs in the coding region were confirmed by sequencing, which were T113G and G116C respectively. The relationships between the genotypes and cashmere fibre diameter, combed cashmere weight, cashmere fibre length and guard hair length were analyzed. There were significant differences between the associations of the different genotypes with cashmere weight (p<0.01), cashmere length (p<0.05) and hair length (p<0.01). Cashmere fibre diameter was the only trait that was not associated with the genotypes. The animals of genotype AB and BB had the higher cashmere weight compared with the genotype AA. By further analysis, it appeared that the KAP8.1 genotype effects on fibre traits may be due to a mutation at the 113 locus. These results suggested that polymorphisms in the hircine KAP8.1 gene might be a potential molecular marker for cashmere weight in Cashmere goats.

This study is to examine the relation between self-consciousness and appearance management behavior; to grasp the appearance management behavior depending on self-consciousness which older women feel personally; to understand their needs more deeply; and to give support in planning and conducting marketing strategies effectively in the beauty and fashion market. The subjects of this study were aged women ranging 55 to 69 in age, living in Daegu and Geongsangbukdo. 500 questionnaires were distributed and 397 questionnaires out of 440 returned were used in the data analysis. The results through statistic analyses are following: 1. Among older women, the higher social self-consciousness group appeared to pursue six types of appearance management behavior(i.e., weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior) much more than the lower social self-consciousness group. 2. Compared with the lower private self-consciousness group, the higher private self-consciousness group appeared to care for not only weight body-shape care but also skin care, cosmetic care, and cosmetic surgery, clothing behavior with more interest in ordinary times. In terms of hair care, though, there was no significant difference between the higher private self-consciousness group and the lower private self-consciousness group. 3. There was no statistically significant difference between the higher social anxiety group and the lower social anxiety group in weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior.
