This study was performed to analyze the relationship among sebum hydration content of the skin and nutritional intake, serum antioxidant minerals and antioxidant enzymes, and lipid peroxide concentration in 50 female subjects in their 20s. The skin type was divided into Dry Skin, Mixed Skin, and Oily Skin, and the dry skin group was 14%, the mixed skin group was 56%, and the oily skin group was 30% of all subjects. The average age of the subjects was $20.54{\pm}1.43$ years and BMI was 20.66. The average sebum content in each group was in the order of T-zone>forehead>chin>cheek. In case of the T-zone, a significant difference between the dry skin group and the oily skin group was observed, suggesting that the area is most sensitive to sebum content by skin type. Significant differences were not observed in energy and nutrient intakes by skin type. Serum concentrations of antioxidant minerals such as copper, manganese, zinc and selenium were not significantly different among the groups, but the dry skin group tended to be higher than the oily skin group. Serum catalase was significantly higher in the oily skin group (P < 0.05), and MDA was significantly higher in the mixed skin group (P < 0.05). The hydration of the cheek and serum zinc showed a negative correlation, and the sebum content of the cheek and GPx showed a significant negative correlation. The hydration of the forehead and serum copper showed a significant negative correlation, and the hydration of the forehead and GPx showed a significant positive correlation. The hydration of the chin and serum SOD showed a significant positive correlation. With these results, it is considered that the basic condition of nutritional status can affect the skin health.

Recently, there seems to besome problems in the urban visual landscape as a result of continuous economic growth and industrial development. At the same time, the public has begun to be aware of the importance of visual resources, and the necessity for visual landscape conservation and improvement. Therefore, the development of evaluative indicators for systematic visual landscape planning and design is urgent. The purpose ofthis study is to discover evaluative models and indicators for the diagnosis of urban visual landscapes. This study included the selection of 18 physical indicators(statistical data) by literature reviews, adoption of field and questionnaire surveys at 12 autonomous districts in Seoul and surrounding major mountain valleys and river streams(i.e. Mt. Nam and Han-River). The content of the questionnaire is scenic beauty. Moreover, the linear regression analysis between the scenic beauty mean scores and the physical indicator scores figure out the scenic beauty prediction model. As this study suggests, the most important indicators in urban visual landscapes are 'Greens', 'Park' and 'the number of apartment buildings(higher than 20 stories).' Based on the results, greens and parks should be priority elements to considerin urban landscape planning and design. Moreover, since the number of apartment buildings that are higher than 20 stories has a negative correlation with the scenic beauty score, it can be used as basic data for landscape planning. For the scenic beauty prediction models and evaluative indicators suggest a direction of urban management, each indicator becomes basic data for visual landscape planning and design. In following studies, if physical indicators and case studies are added, the scenic beauty prediction models and evaluative indicators could be more synthetic and systematic. Moreover, the development of physical indicators in three dimensions(3D)(i.e. results from visual district analysis, view surface analysis) could be expected to obtain more general and varied results.

This study aims to analyze the expressive aspect of men's shirts through examining the characteristics of men's shirts with the trend of men's clothing well represented and considering the image based on high fashion. As a method of study, I have conducted the theoretical study through the literature data, and the content analysis through photographs from S/S collection in 2005 to F/W collection in 2010. Especially, in the recent men's shirts, the materials of glossy silk, wavering chiffon and jersey tend to appear and various images are represented with the tasteful decoration such as ruffle, pin tuck and embroidery together with pastel color. Thus, the result of this study is as follows: Firstly, the masculine and romantic images are researched as the image emphasizing the beautiful and soft masculine beauty which doesn't lose the masculinity even though they are seasonedwith the feminine elements. Soft masculine beauty is emphasized by using romantic image decoration of frills, beads and pin tuck or silk, jersey and openwork materials etc. Secondly, practical fusion images have been studied as the images emphasizing the freshness with practicality through grafting more than two items onto one shirt. Many designs have appeared representing new shapes by grafting more than two items onto one shirt or obscuring the border line between the items. Thirdly, the avant-garde chic images have been researched as the image emphasizing the chick image through representing unique and odd designs by excessively expressing the silhouette in general shapes of shirts. I come. to find that the mainly the designs, emphasizing the uniqueness and the distinction with transformed shapes of sleeves, cuffs and the length of shirts in exaggerated manners, are appearing. Thus, I intend to provide a reference material which will be useful for the newly created design and researches of figurative characteristics in the future fashion.

This study compares the safety of nail products by reviewing domestic and foreign literature for preparing a safety management plan for reduction of human body exposure to hazardous substances that occur in nail products. We analyzed the cases of exceeding the limit value of hazardous substances. In domestic artificial nail adhesive and nail tip, toluene content was 40.3 times higher than the standard value, chloroform was 22.8 times, and antimony was 15.4 times. In developed countries, it is obligatory to provide material safety data and workplace ventilation equipment through various policy researches. However, there is no safety standard in Korea. Therefore, if the regulations for safety management should be established with each characteristic of nail product, work environment, workers, and consumers, and the awareness of hazardous substance cosmetics should be improved through development and dissemination of various educational programs, it can contribute to disease prevention and health promotion.

This study focused on the evaluation of the antioxidative effects of lotus seeds from golden colored flowers. The lotus seeds were extracted with ethanol and then fractionated into 4 fractions, ethyl acetate (EtOAc), n-butanol, methylene chloride, and n-hexane. The comparison of antioxidative activities of the extract and fractions from the lotus seeds was carried out using an in vitro radical scavenging model and the total phenol content was analyzed. Of the tested extracts and fractions, the EtOAc fraction of the lotus seeds showed the strongest 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity with 96.24% at a concentration of $100{\mu}g/mL$. In addition, the hydroxyl radical scavenging activity of the lotus seed EtOAc fraction was also increased in a concentration dependent manner with the concentrations tested ranging from 5 to $100{\mu}g/mL$. Moreover, the EtOAc fraction showed the highest scavenging activity for nitric oxide and superoxide anion radicals. In particular, of all the extracts and fractions, the EtOAc fraction showed highest contents of total phenols. These results indicate that lotus seeds have potential as an antioxidative agent against oxidative stress involving reactive oxygen species. Furthermore, the EtOAc fraction of lotus seeds includes promising oxidative stress-protective compounds.

The purpose of this study was to investigate the effects of frankincense oil in skin aging animal model. Skin aging was induced by both the irradiation of UVB and the application of squalene monohydroperoxide (Sq-OOH) to the back of experimental animals for 4 weeks. And at the same time experimental materials were applied topically. Six to seven weeks female SHR-1 hairless mice were divided into five groups including normal (N: saline), control (C: UVB+Sq-OOH+saline), vehicle control (VC: UVB+Sq-OOH+jojoba oil), positive control (PC: UVB+Sq-OOH+0.01% retinoic acid) and experimental (E: UVB+Sq-OOH+3% Frankincense oil) groups, five animals each group. Lipid lamella and lipid content in stratum corneum of the E group were almost intact with a regular arrangement which were similar to the N group. Collagen fibers in dermis of the E group were almost intact with a regular arrangement which were similar to the N group. Relatively much less number of mast cells and inflammatory cells were found in the E group compared to the C group. The activities of XO, SOD and CAT were no significant difference between the E and N groups. In conclusion, the application of frankincense oil to the skin aging animal model reduced both the generation of free radicals and the damage of skin tissues. Therefore, frankincense oil can be used practically for the prevention or improvement of skin aging in terms of health promotion and beauty for the people.

To investigate the natural cosmetic ingredients of Benincasa hispida seed extract on skin care, we measured anti-oxidant and anti-inflammatory, and whitening effect. DPPH free radical scavenging activity was increased in a dose-dependent manner. The total phenolic content was higher in methanol extract (22.42±0.002 mgGAE/g) than water extract (9.77±0.002 mgGAE/g). MTT assay was demonstrated that the seed extract did not have a cytotoxic effect in RAW264.7 and B16F10 cell lines. We also examined to find out the inhibitory activity on NO production and secretion of TNF-α cytokine in LPS-induced RAW264.7 cells. In B16F10 melanoma cells, the seed extract significantly suppressed α-MSH induced melanin synthesis. Furthermore, westernblot analysis revealed that methanol extract dramatically downregulated the expression level of MITF, TRP-1 and TRP-2. Taken together, the B. hispida seed extract posses anti-oxidant, anti-inflammatory and skin whitening activities, which might provided its functional efficacy in cosmetic materials.
