Background: The objective of this study was to investigate the effect of packaging material on the growth of rootstock of Liriope platyphylla. Methods and Results: This study examined the effects of two types of packaging material, LDPE (low density polyethylene) and functional film on the growth of the tubers of L. platyphylla, at $5^{\circ}C$. During the 16-weeks of storage period, the ratio of loss and decay of the tubers was examined at intervals of 4, 8, and 16 weeks to detect the quality of the plant. After 16 weeks of storage, the treated tubers were own. Subsequently, plant height and the number of leaves were recorded. The results revealed that functional film at $5^{\circ}C$ was the ideal material for the storage of L. platyphylla tubers. The rate of loss was the highest (57.42%) with a onion net and the lowest (22.12%) with a functional film. Similarly, the rate of tuber decay was highest (8.20%) using onion net and the least (4.60%) when the functional film was used. Conclusions: Thus, the use of the functional film proved to be the most effective in the storage of L. platyphylla tubers when compared with the LDPE.

A silsesquioxane precursor that contains p-methoxycinnamoyl group was synthesized to produce UV absorbing spherical polysilsesquioxane (PSQ) spheres with diameters of 10nm to a few ${\mu}m$ under different conditions. A dispersion of $10wt\%$ in Vaseline of these PSQ spheres with diameters of approximately $0.6{\mu}m$ showed SPF values of 5.7 and the identical dispersion did not turn white when applied to human hands. These UV absorbing PSQ spheres showed higher boosting effect of sun protection factor (SPF) than the well known UV blocking octyl methoxycinnamate (OMC). The results indicated that the PSQ spheres with p-methoxycinnamoyl group should be useful as the ingredients in UV screening functional cosmetics without causing allergies and whitening.

In Korea, the human skin tests to evaluate the anti-wrinkles and whitening effect have been accomplished in accordance with the KFDA guideline. Regarding the data of the visual assessment and machinery evaluation of the results for the human skin test, unpaired t-test have been used in order to compare between the test and the control groups and paired t-test for the comparison of effects for before and after. Descriptive statistics such as frequency analyses was used for the questionnaire evaluation data. In many cases of the European and American clinical test centers, the methodology and the statistical analysis were similar to ours. But, the documentation obtained by repeated application from identical individual has high relation. For this reason, it is desirable to apply RM ANCOVA and RM ANOVA to a visual assessment and machinery evaluation. We suggested that RM ANCOVA and RM ANOVA is the new approach to statistical analysis of human test data of functional cosmetics.

Hesperidin, which is the most abundant flavonoid of Citrus unshiu (Rutaceae), has been reported to possess diverse activities and widely used as functional foods and cosmetics. For the development of functional products, extraction procedure is indispensable. Extraction conditions affect the composition of extract as well as its biological activity. Therefore, we tried to optimize extraction conditions such as extraction solvent, extraction time and extraction temperature for maximum yield of hesperidin using response surface methodology with threelevel-three-factor Box-Behnken design (BBD). Regression analysis showed a good fit of the experimental data and the optimal condition was obtained as ethanol concentration, 59.0%; temperature $71.5^{\circ}C$ and extraction time, 12.4 h. The hesperidin yield under the optimal condition was found to be $287.8{\mu}g$ per 5 mg extract, which was well matched with the predicted value of 290.5 μg. These results provides optimized extraction condition for hesperidin and might be useful for the development of hesperidin as functional products like health supplements, cosmetics and medicinal products.

This study aims to prove the changes, development and social background of Korean male cosmetics over the period of 2000-2010. There were total 574 articles written about male make-up and cosmetics in Chosun Daily, Joongang Daily and Donga Daily, which are the top three Korean local daily newspapers in terms of sales revenue for that period. These articles were analyzed together with social background research from various books and daily newspapers. The analysis of articles was divided into different categories; such as foundation cosmetics, color cosmetics, hair, and the social background. It was found that the articles related to foundation cosmetics were written the most, the articles related to male appearance management were second, articles on other items including how to manage the skin being the least. As for the social background of Korean male cosmetics, first of all, a change in social recognition can be pointed out. The traditional understanding of gender roles has changed, men's appearance management has started to be regarded as a competitive talent, and at the same time, the esthetic viewpoint for men also has changed. One example is the newly made popular term, "flower-handsome man", which shows the new trend of favoring males with nice skin. Second, the expansion of mass culture can be pointed out. As consumers can get information and fashion trends easier and faster, the fashion spreads fast, and this has led to the generalization and popularization of the sense of beauty. Third, the development of scientific technology and medical science can be pointed out. Thanks to the progress in those areas. the extension of youthfulness has become possible and the cosmetics industry was also affected greatly, as shown in the market spread of functional products for anti-ageing and wrinkle control as the interest in anti-ageing has grown. There are benefits from the development of scientific technology, but the problem of environmental pollution has appeared due to machinery and industrialization and thus the issue of well-being has been raised. Rising interest in naturalism, pro-environmentalism and organic cosmetics has influenced the cosmetics industry. In addition, the quantity of ultraviolet rays exposed to our skin has increased due to the air pollution caused by the destruction of environment, leading to increased usage of sun block lotion. Lastly, the influence of consumer society and the expansion of consumerism culture can be pointed out. In the modern society, consumption acts not only as the use of products and services but it also has an important role of mediating individuals with others and the society. The market for male cosmetics has been expanding and the number of men putting on make-up has been increasing rapidly. Therefore, this study is meaningful in that the analysis of the mode of change and the social background are an essential process in order to provide a direction for the future market for male cosmetics.
