This study aims to suggest basic data for developing forest product in Jeongeup City by surveying and analyzing consumer awareness and purchasing behavior. A survey was conducted focusing on local tourist attractions in Jeongeup City, and the analysis was conducted on 234 people. Among the local specialty processed products that the survey participants had experience in purchasing, food was mainly tea, concentrate solution, liquor, snacks and fruit syrup/enzyme. The therapy was shown in order of soap, aroma oil, and lotion. It was found that the purchase cost was more than 10,000 won and less than 30,000 won. Major purchase uses were for direct use and gifts, and 56.8% of the customers were satisfied with the satisfaction of the products, which were found to be purchased because of their good quality, good gift, and good health functions. In the question of 11 kinds of forest products, the subjects were aware of bokbunja, balloon flower, wild flower, deodeok, bracken, durum, and mal, among which bokbunja and wild flower were recognized as the representative forest products of Jeongeup. A cluster of food and therapy product selection attributes was analyzed to find target consumers. As the group that is interested in forest products and values the safety and quality of products is highly recognized, the value of forest products should be increased in consideration of the quality and safety of forest products when developing products in the future.

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.

After prolonged viewing of a moving pattern, a stationary pattern can appear to move in the opposite direction, a phenomenon known as motion aftereffect (MAE). Unlike the classical explanation MAE was not confined to an adapted region; instead it can spread to an adjacent region, which was not adapted previously. In order to examine the relative locus of the mechanism responsible for MAE spreading, a rotating harmonic spiral pattern was presented as an adapting stimulus within an annulus window, and then the duration of MAE was measured in both the adapted annulus region and the non-adapted inner region. Two different kinds of test patterns were used: the same and mirror images of the original adapting pattern. An interesting characteristic of a harmonic spiral is that the orientation of a contour at a given location is different from thar of its mirror image by 90 degrees, and consequently the adapting effect of local motion detector is not expected to occur in the mirror image. The results showed that MAE duration in an adapted region was longer in the same image condition than in its mirror image condition, while MAE duration in an non-adapted region was not found to be different between those two different image conditions. These results suggest that MAE spreading might be produced by the adaptation of global motion detectors, not by local motion detectors.

The study is on the cosmetic solubilizing power of organic plant surfactants. The blended high purity polyglyceryl-10 oleate and polyglyceryl-10 stearate mixtures were synthesized using organically certified raw materials to develop surfactants having excellent solubilizing power. The mixture is called "Solubil ORG-1300". The appearance of this material is a pale yellowish paste, with a specific odor. The specific gravity was 1.12 and it was high purity that acid value was 0.072±0.1. The HLB value of this natural surfactant was averaged = 15.1 and calculated through the Griffin equation. Mechanically it is explained how organic surfactant are available with fragrance and oils. The solubilizing test was determined by eye evaluation method through the dissolving performance test for the two oils and measured the transmittance at 890 nm using a UV spectrophotometer to measure the transparency. The results showed that the concentration of surfactant needed to make Bergamot oil available requires approximately more 2 times. It was also found that the concentration of surfactant needed to make the tocoperyl acetate available was about 8 times higher. Experiments on the solubility resulting from pH changes showed stabilized usable solubilizing power even in acidic areas of pH=3.5, neutral areas of pH=7.2, and alkaline areas of pH=1.5. Experiments on the solubility according to pH variation showed good solubility stabilized in acidic areas of pH=3.5, neutral areas of pH=7.2, and alkaline areas of pH=11.5. As an application of cosmetics, the company successfully developed a prescription for moisturizing activity based on these results, it is expected that a wide range of applications will be available for skin care, baby lotion, sensitivity or atopic skin cosmetics.

Micelles, which are called solubilization formulation, have been widely used in skin lotion, mist or various formulations for the purpose of solubilizing the fragrance rather than the role of the active ingredient carrier because the particles are very small. In this study, we developed the swollen micelle having a transparent appearance to deliver ${\beta}$-sitosterol. When preparing the swollen micelle, solubility parameter was considered with active ingredient. This method allowed insoluble active ingredient to be safely entrapped inside the micelles. Stability of micelle was evaluated by dynamic light scattering (DLS). The transparency and shape of the micelles were confirmed by cryo-TEM. In addition, through the thermal analysis using DSC, ${\beta}$-sitosterol was found to be stably present in the swollen micelles. These results indicate that swollen micelles considered solubility parameter could be used as a new carrier for the insoluble active ingredients.

This study investigated the antioxidative effect of mugwort (Artemisia vulgaris L.) extracts in hairless mouse skin from oxidative stress induced by UV-irradiation. After topical application on hairless mouse back with basic skin lotion group (control), ascorbic acid group (AA-0.5%, AA-1.0%, AA-2.0%, and AA-5.0%), and mugwort extract group (ME-0.5%, ME-1.0%, ME-2.0%, and ME-5.0%), the animals were irradiated to increasing doses of UVB (60 $mJ{\sim}100$ mJ) for 4 weeks. Hydrogen peroxide of hairless mouse skin homogenate significantly decreased in 2% (p<0.05) and 5% (p<0.05) of ME and AA groups. Hydroxyl radicals were decreased significantly in both of 2% and 5% ME groups as compared to AA groups (p<0.05). Oxidative stress levels deduced by oxidized protein contents were greatly decreased ($14.6{\sim}18.5%$) in all ME treatment groups, while only at 2% of AA treatment group. Lipid peroxide contents were greatly inhibited in all ME and AA treatment groups (p<0.01). Application of ME significantly increased catalase activity, over 25% in all mugwort and AA groups. Glutathione peroxidase activities were increased up to $20.5%{\sim}32.8%$ in 2.0% and 5% ME groups, whereas it increased in all AA groups. These results suggested that mugwort extract was more effective than that of ascorbic acid in protecting hairless mouse skin from photo-irradiation, and can be used as an potential anti-aging cosmetic ingredients.
