Men study the nature in two ways. Scientists and mathematicians inquire a branch of those two ways. Mathematical formulations are the tools and the expressions of their nature. Meanwhile, the other branch, the art, alms for different inquiry. Instead of formulating the nature, the artists create their masterpieces from their ultimate source, the Mother Nature. For thousands of years these two branches have grown together, influencing each others work. Some mathematicians find that formulation, are not enough to fully express the beauty of nature. It is believed that such a simple expression, formula, easily omits the careful details of nature. The nature is simply too chaotic to be shaped with a formula. Of those mathematicians, Mandelbrot, one of the first to realize this matter, introduced the world of fractal geometry. Fractals give new possibilities. It allows us not to limit ourselves to linear prospect, rather a whole new view of this chaotic beauty of the nature. A popular practice to understand fractals is in costume design. The artistic characteristic and organization mechanism is appalled to costumes. Meanwhile, another practice, rather aggressive, is using computer to create an image of fractals. This image is then used for motives to generate artistic expressions. Computer and paper ironing technique is used for fashion illustration in this research. The works were synthesized arid transformed from computer programs. To add more traditional painting touch to this work, Paper ironing technique was used. Since the of effect of this technique is so random, irregular, and unordered, it corresponds to fractal consideration. This thesis asserts an another prospect to fractal as a structural way of describing nature ailed fashion illustration, rather than restricting it to only mathematical theory.

Black has been the most important color of all since the ancient times when the recognition of black roused, as well as during most of the eras; and can especially be said as the main color which controlled the chronicles of fashion. The purpose of the study was to broaden the application of black color image make-up by inquiring into make-up design elemental characteristics of lines and textures, after classifying magazine illustrations and advertisement make-up images using black. The photos which made effective use of black among fashion illustrations, magazine advertisements after 2001 were classified in to each type, and make-up expression method and characteristics according to design element of each image type was analyzed. The conclusion of such study was the following. 'Erotic image' showed contrast effect between eye make-up and lip color by using pale tone or red color. 'Mannish image' emphasized form and texture of eyebrow by restraining the colors of eyelids with natural brown tone eye make-up; 'Modern image' expressed vague eyebrow to bring the sensation of the direction of eye shadow on eyelids and eye line as well as slant line to relief. 'Kitsch image' showed free and light imagery by creating unique hair style with various colors; expressing lips mostly with colors similar to skin tone or by restraining colors on lips. 'Decadence image' showed messy and foul sensation with unstandardized eye make-up and matt skin of shimmer, glossy and pale tone, also with black colored lips; 'Retro image' expressed reinterpretation of images from 1920${\sim}$1960 to contemporary styles.

This study intended to understand overall history of make-up in Korea in an integrated and diachronic context by interpreting women's will and desire to express themselves reflected in the cosmetics culture in each period centering on women's magazine cover, cosmetics advertisement, and articles from 1950 to 1999 and examining women's make-up image and characteristics in each period. A total of 919 women's magazines (Yeonwon (Women's Garden), Woman Sense, Yeoseong Donga (Women's Donga), Jubusaenghwal (Homemaker's Living), Yeoseong Jungang (Women's Jungang)) issued between 1950 and 1999 were examined for the study. Key words of each period were extracted through fashion and beauty related articles and advertisement titles to examine the make-up culture of Korean women and set the standard for the make-up image of Korean women. A total 1,252 pictures were shot for each period and categorized based on the standard for the make-up image of Korean women. Then, the changes in the make-up image of Korean women were examined and identified the characteristics of images along with the change of images in each period. Next, the meaning of each make-up image was examined. This can be interpreted as the expression of values and desire by modern Korean women, especially Korean women in the late 20th century, as well as the consciousness for coping with the changing society.

The purpose of this study is to develop a design as a high value-added exportable industrial product by developing a cultural product, that can be accepted as having universal beauty by people in the Western cultural area. This is done by, re-analyzing it from a modern perspective after applying the color representation, used in pop art, to Shin Saimdang's Chochungdo (草蟲圖, insects on flowers) which clearly expresses Korea's national emotion and aesthetic consciousness. The research method depends upon developing cultural products such as scarfs, neckties, handkerchiefs, and folding fans, which are communicated in the global market The expressive technique of pop art is utilized after reconstructing the color sensation of pop art in the aesthetic dimension of the natural, physical, and formative beauty of Chochungdo based on the whole understanding of our country's genre of Chochungdo and Western pop art. With regard to the colors in the developed design, the basic colors were extracted and applied by selecting 10 pieces in the flower series, which were made with the silkscreen printmaking technique in the 1970s by Andy Warhol, a master in pop art. A work that integrates pop art, a global art trend, with Korean traditional culture is expected to highlight Korean traditional culture in the global cultural era.

Water chestnut is fruits of Trapa natans var. bispinosa grown wild in Korea. In this study, water chestnut was investigated for anti-pigmentation. Treatment with ethanolic extracts of water chestnut significantly reduced production of melanin in α-MSH simulated B16F10 cells. At 200 ㎍/mL ethanolic extracts of water chestnut, melanin contents were repressed by 43.26% compared to the control group. Additionally, ethanolic extracts of water chestnut reduced expression and activity of tyrosinase, key enzyme in melanogenesis, in α-MSH simulated B16F10 cells. Ethanolic extracts of water chestnut downregulated tyrosinase activity and expression to 23.65% and 62.35%, respectively. These results suggest that ethanolic extracts of water chestnut might be used as a promising whitening ingredients for inhibition of α-MSH-induced melanin synthesis and pigmentation.

This study identifies formativeness and the Korean consciousness of the vernacular design in a Korean designers' collection in order to discover the internal characteristics of vernacular expression elements. The study is based on a theoretical review and an analysis of cases collected from Korean fashion designers' clothes. Research is limited to international collections of clothes presented by Korean fashion designers since 2,000. The process of Korean vernacular designs in fashion were analyzed for formativeness in form, color, pattern and detail. The research findings identified formativeness and Korean's consciousness of modern fashion designs that reflect vernacular designs as follows. First, they are round, flexible line and shape based on assimilated with nature, rhythmic curve to express life force and asymmetry based on an ecstatic world based on nature. Second, a white color explained the pure mind and racial peculiarities in regards to the five colors that expressed the thinking of traditional rituals such as prayers for comfort of life and ancestor worship. Third, there were patterns around shape of nature, praying, and Korea culture. Finally, there were skills of Korean traditional handcrafts such as embroideries, knit-works, gold foils, and quilts where clothes expressed the hardship of life and strong willpower to overcome. In conclusion, the clothing of Korean vernacular designs contains characteristics such as natural beauty, decorativeness, shamanism, and eclecticism.

Objective : The purpose of this study was to investigate the anti-inflammatory effects of aqueous extract from Scolopendrae Corpus (SC) on lipopolysaccharide (LPS)-induced inflammatory response. Methods : To evaluate the anti-inflammatory effects of SC, we examined the inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines (TNF-a, inteleukin (IL)-$1{\beta}$ and IL-6) on RAW 264.7 cells. We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and inhibitory kappa B a ($I{\kappa}$-Ba) using western blot. Furthermore, we also investigated the effect of SC on LPS-induced endotoxin shock. Results : Extract from SC itself had not any cytotoxic effect in RAW 264.7 cells. Aqueous extract from SC inhibited LPS-induced NO production and iNOS expression. SC pre-treatment also inhibited IL-$1{\beta}$, IL-6 production in RAW 264.7 cells. To investigate inhibitory effects of SC on inflammatory mediators, activation of MAPKs was examined. SC inhibited the phosphorylation of p38 kinases (p38), c-Jun $NH_2$-terminal kinase (JNK) and also the degradation of $I{\kappa}$-$B{\alpha}$ in RAW 264.7 cells stimulated with LPS. Furthermore, SC administration reduced LPS-induced endotoxin shock. Conclusion : SC down-regulated LPS-induced production of inflammatory mediators through inhibition of activation of p38, JNK and degradation of $I{\kappa}$-$B{\alpha}$. Taken together, our results suggest that SC may be a beneficial drug against inflammatory diseases such as sepsis.

Objective : This research has been conducted to comparative analysis of anti-inflammatory effects to suggest a usefulness of ethanol extracts fromGentianae sino-ornata(GSO) as a functional material for inflammatory activities.Methods : Cell viability was measured by neutral red (NR) assay, and nitric oxide (NO) production in RAW264.7 cells was monitored by measuring the nitrite content in culture medium. The expressions of cyclooxigenase-2 (COX-2) was determined by western blot analysis, and Inducible nitric oxide syntase (iNOS) and cytokine were determined by reverse transcriptase-polymerase chain reaction (RT-PCR).Results : When the GSO extract was added the concentration of 5-20 ㎍/㎕, the viability of cells was maintained 90% or more at all levels. NO production was suppressed by the treatment of GSO in LPS-stimulated RAW264.7 cells. GSO inhibited the expression of iNOS, COX-2, IL-1βand IL-6 in LPS-stimulated RAW264.7 cells.Conclusions: From this results, we consider that GSO can be a useful therapeutic and preventive approach to various inflammatory diseases as a functional material for inflammatory activities.

In this study, the functional cosmetic activity of hot-water (AW) and methanol(AM) extracts from Apocynum lancifolium Russanov are examined. In the DPPH antioxidant activity test, the AW extract showed the highest inhibition rate of 90.5% (IC50 37.717 ± 8.209 ㎍/mL) and the antioxidative activity of ABTS showed a high activity in the AW extract with an IC50 of 185.244 ± 12.602 ㎍/mL and 96.2%, respectively. In RAW264.7 macrophages, the two extracts significantly suppressed the LPS-induced nitric oxide (NO), TNF-α, IL-6 production and iNOS expression level. The MTT assay measured by the cell survival rate showed that AW and AM extracts have no toxicity. The astringent activity of the AW extract exhibited the highest astringent activity with 74.336±2.487 mg/mL. Therefore, these results suggest that A. lancifolium extracts have a health promotion potential which can be further developed as food additive, natural products for cosmetic purpose.

The aim of the study was to evaluate the physiological activity of Lycium ruthenicum to investigate their potential as a raw material that can be used in the cosmetic industry. L. ruthenicum fruit extracts were obtained using 70% methanol(LRM) and hot-water(LRW). The DPPH and ABTS radical scavenging abilities were higher in the LRM extract than in the LRW extract. The FRAP value of LRM was about 1.3-fold greater than that of LRW. The polyphenol contents of LRM and LRW were 31.883±1.395 mg/g and 27.748±2.741 mg/g respectively. LRM inhibited the generation of NO in LPS-stimulated RAW264.7 cells. LRM also attenuated the expression of COX-2, PGE2, IL-6, and TNF-α induced by LPS. These results suggests that L. ruthenicum fruits could be use as a source of natural antioxidants and anti-inflammatory agent in cosmetic products.
