The Ulmus davidiana have been used in traditional oriental medicine as remedies for inflammation, ulcers, cancers, bacterial infections and scabies. In this study, the anti-fungal, anti-oxidant, and anti-inflammatory activitiesof a supercritical extract of U. davidiana were investigated in vitro. To explore the anti-oxidant and anti-inflammatory characteristics of the supercritical extract, ABTS radical scavenging activity, and the inhibition of nitric oxide production in LPS-stimulated RAW 264.7 cells were examined, respectively. In addition, the anti-fungal activities of the extract were assessed. The results showed a concentration-dependent increase in ABTS radical scavenging activity. Cells stimulated with LPS produced more nitric oxide than normal control cells; however, cells treated with the supercritical fluid extract decreased this production in a concentration-dependent manner. Finally, the supercritical fluid extracts showed significant anti-fungal activity. These results suggest that extracts of the U. davidiana might be used to develop potent anti-fungal, anti-oxidant, and anti-inflammatory agents, and may be useful as ingredients for related new functional cosmetic materials.

This study aims to investigate the status of using medicinal herb cosmetics targeting women who had experiences of using medicinal herb cosmetics and present basic data for future development of medicinal herb cosmetics that can satisfy the needs of future customers and convergence marketing strategies. For the purposes, this study conducted a frequency test and a chi-square test (${\chi}^2$) on the 351 copies of responses obtained from a survey targeting adult women to identify the use status according to perceptions on medicinal herb cosmetics. As a result, the followings were presented: As the subjects were older, they preferred medicinal herb cosmetics and intended to keep purchasing it. Customers had more confidence in the medicinal herb cosmetics when the cosmetics were good-quality. In respect to efficacy difference according to prices, the subjects who believed that there was difference in efficacy according to prices were more satisfied with the medicinal herb cosmetics and purchased products of higher price. Such results indicate it is suggested that medicinal herb cosmetics would develop further when cosmetic products that can satisfy their need are developed.

We investigated the morphological characteristics of the pearlescent pigment by using scanning electron microscope, energy dispersive X-ray spectrometry and thermal analyzer. The result is that the shape of pigment is platy polygonal form through observing the pearlescent pigment by the scanning electron microscope. The size of pigment is various and not formed in standardized size or shape. The pigment flakes were measured about from $30{\mu}m$ to $300{\mu}m$. The tip of the piece of pigment is pointed shape or angled. The result of observing them by the scanning electron microscope in magnifying high power is that the edge and the lateral face of them is an round form and the measurement of thickness is about $9{\mu}m$. As well using the high magnification scanning electron microscope, the surface of the pigment flake observed like rugged as coating with the $TiO_2$ element, the diameter of the coating particle is around 60 nm, then the coating particle consists of granular substance. Analysis of the configuration elements of pearlescent pigment using by the energy dispersive X-ray spectrometry is that O, Si, C, Na, Ca, Ti, Zn detected in the surface of pigment and its lateral face identifies similar components. In thermal analysis, there are no contained quantity differences between them in beginning from $100^{\circ}C$ to $800^{\circ}C$ showing thermal analysis, 1.1% out of contained quantity reduced at $115^{\circ}C$, 1.7% dropped at $416^{\circ}C$, and 1.9% decreased at $797^{\circ}C$.

In the rapidly changing 21st century, image management has become more important. Under these circumstances, as a lot of hair colors and beaching agents are used to create diverse hair colors, hair damage resulting from frequent chemical hair coloring has been inevitable. This study investigated how to reduce morphological changes in hair and hair damage after dividing hair into healthy hair('Group A') and damaged hair('Group B'), using the following bleaching agents: basic bleaching agent(a), beaching agent diluted with water(b), oil ingredient-added bleaching agent(c), water-shampoo mixed bleaching agent(d). The results found that even though hair damage can be prevented by a bleaching agent diluted with a mixture of diverse additives, there were better effects on hair texture in both 'Group A(4.83)' and 'Group B(4.41)' at a sensory test when hair was bleached with an addition of Camellia oil, according to blinded experiment, in particular. As a result, hair damage could be reduced. Therefore, this study expects that hair bleaching with an addition of Camellia oil to the mixture of a bleaching agent would bring the development of diverse new materials which can minimize hair damage as well as regulate hair brightness and make a contribution to the development of cosmetology market.

Arts is the expression of reasoning and conscious life of human and arouse human the concept of existence, utmost emotion and excellent thoughts. Also it makes humans life very abundant. I make it come first to get rid of the art thirst on the opposite sight of technical one for hair as on part of humans body. Next purpose is that to confirm the esthetic value of 'hair arts' by solidify the academic ground of beauty arts through creating 'hair arts' works and learning and make the direction for the beauty industry and education of the next generation. In this study I investigated the Greek myth and the hair styles of ancient Greek Goddesses. On the basis of that symbols I elaborated hair formative works made of metal and studied, analyzed and displayed that. Work No.1 'aphne' pictures the second of changing into a laurel tree avoiding the love. Secondly 'Muse Erato' was exhibited the peaceful figure that have enough the fine melodies. 'Leda' brings out the feature of Leda resembling a swan and the fourth piece, 'Eos' conveys the brilliant and mystery of dawn. So this study conducted based on the concept of practical hair and have made efforts to be close to theoretical manufacturing research needed at making hair arts works and academic one needed at organic design composition for pioneering new field, 'art hair.' I hope these 'hair arts' works make creativity of the practise hair alive. It will be very thankful to me if this study can help even though slightly for splendid beauty arts to make its status firm as a one part of arts, and there are following studies.

This study investigated up-styling techniques as related to wedding dress image. To find up-styles that fit well with a wedding dress, a questionnaire survey was conducted targeting hairdressers in the beauty industry, and new styles were created and suggested based on the survey results. For this, hair was slicked back without parting and combed upward. Then, using braiding techniques needed to produce a top point, styles were created to create attractive images. For up-styles that go with an elegant wedding dress, hair was parted in a ratio of 3 : 7. In addition, a roll technique was applied based on natural points by keeping the ears half-covered to create elegance. For up-styles that are perfect for a classic wedding dress, hair was parted in a ratio of 2 : 8, keeping the ears half-covered. Based on the back point, a twisting technique was applied to create classic images. It is anticipated that the study results would provide basic data needed for creating and understanding up-styles that go with various wedding dress images and make a contribution to their development.

I have analyzed the present status of national certifications and qualifications systems in overseas countries in order to come up with improvement alternatives to National Qualifications Framework(NQF). Most national certifications and qualifications systems at home and abroad have introduced, implemented or are in the process of modifying evaluation programs on the basis of Level 8. I have come to the conclusion that certificates and qualification titles equivalent to those for education programs in cosmetology related departments should be developed for high school to the masters and PhD diplomas, at the same time, the certification program to foster industrial engineers as well as master craftsman for skin & nail-care as well as makeup courses that are not available in beauty field, and I expect this study to be used as the basis material for onsite education & training programs for professionals in beauty field whose capability are respected upon acquisition of relevant certificates in relations with cosmetology related education courses.
