We analyzed the hair microstructure of Korean small terrestrial mammals, such as Rodentia and Lagomorpha, to classify the characteristics of hair morphology. Micromys minutus showed a unicellular irregular type of medulla structures; on the other hand, the other mammals showed multicellular structures. Regarding the cuticular scale structures, the Rodentia species exhibited a narrow and broad diamond petal type, while the Lagomorpha species exhibited an elongated petal type. Interestingly, the hair cross-sections showed quite unique characteristics. We constructed hair identification keys to distinguish species with a single hair. The dichotomous key of Rodentia and Lagomorpha can be used for their behavioral ecology and dietary analysis of upper predators to serve as the basis for ecological research.

The purpose of this study was to develop a lifestyle scale for one-person hair salon users and to identify differences in store choice factors and hairstyle pursuit behaviors according to lifestyle types. Data was collected by survey, with 225 responses being included in the analysis. Data analysis was performed using cross-analysis, factor analysis, Cronbach's α, cluster analysis, ANOVA and the Duncan-test using SPSS 23.0 analysis software. The results of the study were as follows. First, one-person hair salon users were classified according to the following lifestyle groups: The rational appearance management group, the passive appearance management group, and the discriminative appearance management group. Second, store choice factors according to lifestyle group showed significant group-specific differences in relation to store atmosphere, accessibility, and promotion. Conversely, comfort of space in store and word-of-mouth recommendation message were high for all three groups, indicating that these are important factors in relation to store selection. Third, with regard to hairstyle pursuit behaviors according to lifestyle, the discriminative appearance management group showed the same characteristics as high involvement groups that regard all dimensions of hairstyle pursuit behavior as important. The results of this study can be used to suggest efficient operations for one-person hair salons and to suggest differentiated marketing strategies to increase the demand of one-person hair salon users.

In China, the phenomenon called 'Korean Wave' has boosted the interest in Korean pop culture, such as TV drama, music and films, and even in the general culture and society. As Korean singers, movie actors and talents become popular beyond acceptance of public culture, those who learn Korean, buy Korean products and visit Korea have emerged. Especially, most Chinese women have used Korean hair cosmetics and the interests in Korean hair cosmetics are increasing, since cosmetic companies entered China early due to Korean wave. Thus, the status of purchase of Korean hair cosmetics is growing day by day in China. In particular, since the environment is established to buy hair cosmetics easily in Myeong-dong which is one of the shopping tourism special districts, many Chinese tourists are crowded there. Based on such phenomenon, this study explored the differences in perceptions towards 'Korean Wave' among Chinese tourists who purchased Korean hair cosmetics in Myeong-dong, and analyzed the factors that largely determine the interest in Korean hair cosmetics and their purchase behavior. Therefore, this study is aimed at contributing to the development of hair cosmetics products and the market amid Korean Wave. As the research methods, 100 answered questionnaires were collected with target of Chinese tourists at 20s and 40s who purchased Korean hair cosmetics in Myeong-dong once 120 questionnaires were distributed. In-depth analysis was conducted and final research data were used. It was confirmed that Korean fever positively affected the Chinese tourists' purchase behavior and satisfaction of hair cosmetics, and the interests in Korean hair cosmetics at 20s were higher than at 40s. People at 20s had higher awareness, satisfaction and intention of repurchase of hair cosmetics compared rather than people at 40s. The research confirmed that Chinese tourists are very interested in Korean hair cosmetics as the pop music craze has led to the general Korean Wave, and differences in such perceptions have led to significant differences in the product purchase behavior.

Background: Recently, substances from seaweeds have been widely used in hair growth solutions, and have been proven to be effective. Seaweeds have been documented to possess hair growth activity; however, no report on the effect of seaweed on hair regeneration has been issued to date. In this study, we investigated which exact substance of hair tonic made by JW-bio and our institute shows effects on hair growth by studying the mechanisms of candidate substances. Methods: The study was conducted to investigate the hair restoring effect of domestic natural substances; we categorized the candidate substances as seaweed, cereal, and herbal medicine. Five experimental groups were included in the study as follows: a saline group, a 50% ethanol group, seaweed group, a cereal group, and a herbal medicine group. Results: Three extracts (seaweed, cereal, and herbal medicine) were administered to C57BL/6 mice for two weeks after depilation. Depilated areas were found to be completely covered with fully grown hair, and the hair re-growth score was highest in the seaweed group. Using a hair analysis system, hair characteristics were measured in all groups on days 10 and 14 after depilation. The width and length of hair follicles were largest in the seaweed group. Groups treated with seaweed showed significantly increased gene expression of insulin-like growth factor-1. Groups treated with all the three extracts showed decreased expression of transforming growth factor-${\beta}1$. Conclusion: Findings from our study suggest that seaweeds possess hair-growth effects and may be useful for the treatment of alopecia in the future.
