The effects of high energy short wave solar radiation on human skin have received much publicity as the major cause of accelerated skin ageing and of skin cancers. To meet public demand, the cosmetic industry has developed sun protection factor products, which contain a variety of so-called "UV filters", among others benzophenone (BP) and its metabolites are the widely used UV filters. UV filters are also used to prevent UV light from damaging scents and colors in a variety of cosmetics products and to protect of plastic products against light-induced degradation. There are many variants of BP in use. In this respect, to regulate and to evaluate the hazardous effect of BP-type UV filters will be important to environment and human health. The genotoxicity of 7 BP-type UV filters was evaluated in L5178Y $(tk^{+/-})$ mouse lymphoma cells in vitro. BP, benzhydrol, 4-hydroxybenzophenone 2-hydroxy-4-methoxybenzophenone and 2, 4-dihydroxybenzophenone did not induce significant mutation frequencies both in the presence and absence of metabolic activation system. 2, 2'-Dihydroxy-4-methoxybenzophenone appeared the positive results at the highest dose, i.e. 120.4 ${\mu}g/mL$ only in the absence of metabolic activation system. And also, 2, 3, 4-trihydroxybenzophenone revealed a significant increase of mutation frequencies in the range of 138.1-207.2 ${\mu}g/mL$ in the absence of metabolic activation system and 118.3-354.8 ${\mu}g/mL$ in the presence of metabolic activation system. Through the results of MLA with 7 BP-type UV filters in L5178Y cells in vitro, we may provide the important clues on the genotoxic potentials of these BP-type UV filters.

With the rapid growth of the Chinese cosmetics market and the continuous introduction of new products into the market, beauty videos generated by other consumers, that are by beauty vloggers, have become a major source of information for cosmetics consumers. With the popularity of beauty vlogs in China, beauty vloggers have become influencers who affect consumers' information processing and attitude development regarding cosmetic products and beauty routines. The current study aims to explore the characteristics of beauty vloggers that affect consumers' attitudes toward both the beauty vlogs and the products featured in those vlogs. Based on parasocial interaction theory, the study examines whether perceived characteristics of beauty vloggers influence consumers' perceived parasocial interaction, which in turn influences their attitudes. The study employs an online survey, which was administered to female consumers in China. Data from a total of 372 responses was used for analysis. Findings show that the perceived similarities to and perceived trustworthiness of vloggers have a significant impact on parasocial interactions, which influences consumer attitudes toward both the vlogs and the products shown in them. Perceived reliability and perceived attractiveness are shown to have a positive impact on consumer attitudes toward vlogs. Perceived expertise, attractiveness, similarity, and trustworthiness have all been shown to affect product attitudes. These results show that while beauty vlogs have a significant impact on consumers' decision-making processes, the perceived characteristics of beauty vloggers themselves are important to consumers in the development of their attitudes toward both vlogs and products.

Styela clava tunic is generated in large amounts as a waste from S. clava processing plants and causes environmental problem. Although biological activities of S. clava were reported by many investigators, study on S. clava tunic was little. In this study, therefore, tyrosinase inhibition and antioxidative activities of extracts from S. clava tunic using different solvent were investigated for recycling of the fishery waste. Among extraction methods tested, autoclaved extraction (25.7%) and hot water extraction (18.2%) appeared to be effective for extraction. The highest total phenolic content was 46.6 mg/g in autoclaved extract while the highest flavonoid content was 23.0 mg/g in chloroform extract. All extracts possessed tyrosinase inhibition activity and the inhibition activity was concentration-dependent. Inhibition concentration ($IC_{50}$) against tyrosinase activity was $0.36{\times}10^4$ mg/ml in ethanol extract, $0.11{\times}10^3$ mg/ml in acetone extract and 0.27 mg/ml in n-butanol extract. Among extracts tested, hot water and autoclaved extracts displayed higher antioxidative activity than organic solvent extracts. Therefore, our data suggest that extract from S. clava tunic may potential candidate for cosmetic product with whitening effect and medicine for diseases caused by various oxidative stresses.

This research examined the effects of Narcissism as socio-psychological factor and physical features such as BMI on the selfie behavior. The participants of the study were SNS users aged 20-29 years recruited in Daegu and surrounding areas. Statistical analysis including factor analysis, ANOVA, cluster analysis and regression was done using SPSS 23.0 to analyze the results. Two groups with high other-dependent Narcissism showed higher levels of Cosmetic surgery management and clothing management compared to other groups. Among 4 clusters divided by BMI, the lower the BMI, the higher the level of appearance management behavior except for body management. Other-dependent Narcissism and BMI have been shown to have a significant effect on selfie behavior in the relationship of Narcissism, BMI and selfie behavior. In the relationship between appearance management behavior and selfie behavior, only beauty treatment management influenced selfie improvement behavior, and all appearance management behaviors affected selfie complement behavior. Fashion brands should use the relationship between Narcissism, appearance management behavior and selfie behavior in planning selfie related events on SNS as well as consider active collaboration with cosmetics brands. It is necessary to investigate selfie behavior from a more diverse perspective by expanding future research targets and diversify related variables.

Cosmetics retailers would benefit from studies that examine which shopping-mall attributes can be manipulated to favorably affect consumer satisfaction and revisit intention at Internet. The purposes of this study were (1) to examine the dimensionality of shopping-mall attribute for cosmetics retailers, (2) to determine which dimensions of shopping-mall attribute were significant predictors of consumer satisfaction and revisit intention and (3) to find out the moderating effect of consumer satisfaction through shopping-mall attributes on revisit intention to buy cosmetics across the types of shopping-mall at Internet (i.e., total mall and specialty mall). Data were collected from 209 online cosmetic shoppers among high school girls. Factor analysis identified five dimensions of shopping-mall attributes at Internet, such as Convenience, Price, Loading speed, Sales promotion, and Service. Only two dimensions(i.e., convenience and service) were significant predictors of online shopper satisfaction in both total mall and specialty mall. The moderating effect of consumer satisfaction on revisit intention was significant in both two mall types at Internet. For total mall, price was a significant predictor through consumer satisfaction on revisit intention, while loading speed was a significant predictor directly on revisit intention for specialty mall. In light of the major findings, this study sets forth strategic implications for consumer satisfaction and revisit intention to buy cosmetics in the setting of electronic commerce.

This study is to enhance the competitiveness of the domestic cosmetic industry and provide basic materials needed for a design idea by analyzing perfume bottles designed by Rene Lalique. The methods of this study are documentary research and demonstrative research. The documentary research considered the theoretical background with a focus on related domestic and international literature, previous research, and Internet materials. The demonstrative research extracted photo materials of the bottle designs of Lalique from domestic and international web sites along with literature that classified them into shapes, colors, materials, and patterns that analyzed the general characteristics and chronologic changes. The results of this study are as follows. The curve-oriented shape was common and multi-colors were used more frequently than a single color in the 1910's. Colorless-transparent glass and a flower patterns were used frequently for materials and patterns, respectively. Lalique reflects this style in his bottle designs because the Art Nouveau effect in the 1910's. In the 1920's, curved and straight shapes had a similar percentage. The use of multi-colors and one type of glass bottle increased versus the 1910's. Similar to the 1910's, a flower pattern was used most frequently. This suggests that Lalique was influenced by the established Art Nouveau and was also interested in the Art Deco style, In the 1930's, an organic curved shape was common. Unlike the 1910's and 1920's, a single color was more common than multi-colors. The one type of glass bottle and a geometric pattern were common for materials and patterns, respectively. The Art Deco style was reflected in the bottle design of Lalique in the 1930's.

The compound 3,4-dichloroaniline (DCA) is an aromatic amine used as an intermediate product in the synthesis of herbicides, azo-dyes and harmaceuticals. It is also a degradation product of some herbicides (diuron, propanil, and linuron) and of trichlorocarbanilide, a chemical used as active agent in the cosmetic industry. 3,4-DCA, however, is considered potential pollutants due to their toxic and recalcitrant properties to humans and other species. A bacterium capable of growth on 3,4-DCA was isolated by dilution method from 3,4-DCA-containing enrichment culture. Finally, a strain, YM-14, capable of degrading efficiently 3,4-DCA was isolated from a sandbank. The isolated strain, YM-14 was identified to be Arthrobacter sp.. Fifty ppm 3,4-DCA in 1/10 LB media was completely degraded by the growth of Arthrobacter sp. YM-14 for 12 h at $30^{\circ}C$. The isolated strain is capable of growth on 3,4-DCA as sole carbon source and also able to degrade other chloroaniline compounds. Also, the isolated strain showed high level of catechol 1,2-dioxygenase activity by 3,4-DCA exposure. The catechol 1,2-dioxygenase was supposed to be ones of the important factors for 3,4-DCA degradation.
