This study was conducted to determine the antioxidant and anti-aging activities of water-soluble compounds extracted from Inula Flos (IF), Chrysanthemi Flos (CSF) and Carthami Flos (CTF) at 25℃ and 80℃. The 80℃ CTF extract included soluble protein (386.44 mg/g), reducing sugar (101.27 mg/g), flavonoids (42.70 mg/g), and polyphenols (123.96 mg/g). The DPPH radical scavenging activities of all extracts were over 50% at 0.1 mg/mL; the 25℃ CTF extract showed a significantly higher effect than ascorbic acid at 1.0 mg/mL. Xanthine oxidase inhibition, SOD-like activity and tyrosinase inhibition of the 80℃ IF extract were 32.14%, 31.54%, and 42.01% at 2.0 mg/mL, respectively. The elastase and collagenase inhibition activities of the IF 80℃ extract were 34.67% and 31.40%, respectively. The nitrite scavenging abilities of 25℃ IF and CTF extracts along with 80℃ CSF and CTF extracts were over 95% (at 2 mL, pH 1.2), even higher than ascorbic acid; and nitrite scavenging ability of the 80℃ CTF extract was 87.30% (at 2 mL, pH 3.0), similar to ascorbic acid (87.36%). These results suggest that the 80℃ CTF extract contained useful compounds and IF is a potentially useful antioxidant and anti-aging source for the development of functional cosmetics.

The water and 70% ethanol extracts of Equisetum arvense fertile stems were carried out to investigate the whiting, anti-wrinkle and physiological activity of the possibility as a cosmetic material. The contents of soluble protein of water and ethanol extract were determined as 21.96 mg/g and 23.07 mg/g, respectively. The reducing sugar contents of water extract contained 147.54 mg/g and ethanol extract contained 108.83 mg/g. The contents of flavonoid and polyphenol compound of water extract were 28.45 mg/g and 22.36 mg/g, that of ethanol extract were 28.25 mg/g and 26.72 mg/g, respectively. The tyrosinase inhibition activities of both extracts were less than 10% inhibition. The collagenase and xanthine oxidase inhibition of water extract were 18.86% and 33.82%, that of ethanol extract were 24.96% and 37.25% at 1.0 mg/mL. The electron donating ability of water extract was 94.60% and that of ethanol extract was 87.21%, respectively. In the analysis of nitrite scavenging ability of pH 1.2 condition, ethanol extract (64.44%) showed a significantly higher effect than water extract (43.51%). The SOD like activity of water and ethanol extract showed less than 17% at 1.0 mg/mL concentration. This suggest that the ethanol extract of E. arvense fertile stems have the potential to be used as physiological activity source for the beauty food and cosmetic material.

Composition Design Line Creation, one of a large variety of ideas for fashion design will start from the most basic elements of line. Therefore, when a Fixed Composition design is applied with decoration lines, is very important the line characteristics and design elements and principles appropriately. The results of analyzing decoration ot the characteristics applying composition Design Line Creation shown in fashion design collections from the 2C03S/S~2010S/S reveal that the most popular style of garment had one decorative detail; the major kinds of decorative detail were pleats and the dominant color scheme. Generally, people think that a lots of decorative detail and a wide variety of color make for good fashion: but one or two types of decoration and a color scheme based on one dominant color are more effective. The results of the analysis in this study can contribute to the fashion design in which the above composition design line of decorative detail method is applied.

Internationally competitive fashion design to keep up with the modern era can be created only by understanding design forms based on a new artistic creation idea together with a new modern fashion trend. To achieve this, a sense of line appreciation should be enhanced based on the composition design line shown in recent collections, and a sense of designing with one's own unique style should be promoted by recomposing new design lines. The results of analyzing composition design lines shown in fashion design collections from 2005 S/S to 2009 S/S are as follows. First, among basic composition design lines, five representative composition design lines appeared mostly distinctively. Second, kinds of combination lines shown in composition design line combination expressed in fashion can be classified into four. The most noticeable line is a vertical line which is shown essentially in all composition design line combination. The second noticeable pattern is the combination of horizontal and vertical lines as basic lines, and addition of diagonal line or curved line to those basic lines. Third, characteristics of the composition design lines applied in fashion include recomposing composition design lines with new image and free variations such as diverse movements and realignment of lines and dimensions of the basic composition design lines. Within given basic composition design lines, only a portion of the line, not the entire line, is omitted or modified. Thus there is no addition of totally different lines nor line variation in a complicated style which merges with other composition design lines. Accordingly, creative idea of fashion design applying composition design line is a method of obtaining a creative idea to understand lines as a sign of idea, create a new form by modifying the lines, and obtain new ideas which enable reinterpretation of the design. The results of the analysis in this study can contribute to the fashion design in which the above composition design line method is applied.

Hot water extracts of fertile and sterile Equisetum arvense Linne stems were used to investigate their anti-oxidative anti-aging properties and their possible use in beauty foods or cosmetic materials. The contents of polyphenol and flavonoid compounds of fertile stem extracts were 27.06 mg/g and 45.62 mg/g, respectively. The sterile stem extract contained 191.14 mg/g of reducing sugar and 56.14 mg/g soluble protein. The nitrite scavenging abilities of fertile and sterile stem extracts at pH 1.2 and 2.0 mg/mL were 92.24% and 81.65%, respectively. At a concentration of 2.0 mg/L, the superoxide dismutase (SOD)-like activity, xanthine oxidase (XO) inhibition, tyrosinase and collagenase inhibition capacities of fertile stem extract were 24.77%, 61.48%, 28.16% and 29.68%, respectively, while those of sterile stem extract were 16.58%, 25.57%, 52.88% and 37.47%. The DPPH radical scavenging capacity at a concentration of 0.05 mg/ mL (fertile stem extract, 44.94%; sterile stem extract, 40.82%) was higher than L-ascorbic acid (36.95%), and all extracts showed greater than 90% scavenging ability even at a concentration of 0.5 mg/mL. As a result, E. arvense fertile stem extract showed the highest nitrite scavenging, SOD-like activity, xanthine oxidase inhibition, tyrosinase and collagenase inhibition, while sterile stem extract had the highest amount of reducing sugar, soluble protein and collagenase inhibition. These results suggest that hot water extracts from fertile and sterile E. arvense stems might be considered as potentially useful for the development of beauty foods and cosmetics materials.
