In this study, Korean-cultivated Houttuynia cordata Thunb. (HC) was extracted anti-inflammatory effects of extracts were compared in order to confirm the possibility of natural cosmetics as a raw material. HPLC pattern analysis, cell viability assay, total phenolic contents, ABTS/DPPH radical scavenging analysis, measurement of ROS production, griess reagent assay, and luminex technique. The content of quercetin was higher in fresh Houttuynia cordata (HC-F) than in dried Houttuynia cordata (HC-D). Also, content of HC extracts shows a difference in the content of the two representative compounds (polyphenol and flavonoid) according to the stored differently. ROS production showed higher inhibitory rates at HC-F. The anti-inflammatory activity of HC-D was shown higher than that of HC-F. But, in the measurement of the reduction in inflammatory cytokines, IL-1β showed that HC-D had a relatively high reduction effect, and IL-6 and TNF-α showed a high reduction effect. And these results will be a basis for the development of cosmetology in skin care and improvement of skin problem.

This study analyzed the content of special selling events in internet shopping malls to establish academic standards for special selling events as tools for sales promotions and to suggest systematic guidelines for marketers designing special selling events. Based on a content analysis, the titles of special selling events from four internet shopping malls selling women's apparel were analyzed. A total of 692 titles were analyzed. The results are as follow. First, the contents categories of special selling events could be classified into two groups such as 'theme' and 'tool'. Season, product characteristics, style, advice/information, brand, annual/social events, and marketing events were the main content categories that came under the 'theme' group; in addition, the price benefit, free offers, product mix, and marketing technique were the main content categories that came under the 'tool' group. Each main content category was subdivided into several segment content categories. Second, most of the titles were composed of more than two segment content categories that involved various information and benefits; however, the portion of titles composed of only theme related content categories or only tool related content categories was substantial. Furthermore, the theme related content categories were more than the tool related content categories. Third, the usage frequencies of the contents categories were analyzed. The upcoming season, single brand, sale/discount, item/material/color, special price/lowest price, and period/time/quantity limits were the segment content categories that held a high rank. Forth, most of the factors that evoked the unplanned purchases of consumers were related to the content categories of special sale events.

This study aimed to investigate the beauty food activities of wild-cultivated ginseng (Panax ginseng C.A. Meyer). wild-cultivated ginseng extracts were analyzed for antioxidant, skin whitening, anti-wrinkle effect was measured in water and 70% ethanol extract. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical decolorization activities of water and 70% ethanol extracts were 16.69 and 2.18% as well as 4.04 and 3.25% at a solid content of $200{\mu}g/mL$, respectively. The antioxidant protection factors (PF) of water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$ were 1.06 PF and 1.09 PF, respectively. Thiobarbituric acid reactive substance (TBARs) were both 96% at a solid content of $200{\mu}g/mL$. As PF and TBARs showed higher activity than DPPH and ABTS, we could know that antioxidant activity in the lipophilic component of wood-cultivated ginseng were superior to water-soluble component of wood-cultivated ginseng. Tyrosinase inhibitory activity was 10.97 and 52.39% in water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$. The collagenase and elastase inhibitory activities as anti-wrinkle effect were 15.71 and 20.43% in water extracts as well as 32.26 and 86.74% in 70% ethanol extract at a solid content of $200{\mu}g/mL$. The results show that anti-wrinkle effect was the best among the other experiments. This extracts from wood-cultivated ginseng, therefore, seems to be a potent beauty food resource against wrinkles.

The Buckwheat Season, evaluated as the best of Lee Hyo-seok's literature, is one of the short stories that represent Korean literature. However, vivid literary expressions such as lyrical and beautiful depictions, figurative expressions and dialects, which show the Korean beauty, rather make learners have difficulty and become a factor that fails in reading comprehension. Thus, it is necessary to revise and present the text modified for the learners' language level. The methods of revising a literary text include the revision of linguistic elements such as cryptic vocabulary or sentence structure and the revision of the composition of the text, e.g. suggestion of characters or plot, or insertion of illustration. The methods of revising the language of the text can be divided into methods of simplification and detailing. However, in the process of revising the text, many depend on the adapter's subjective perception, not revising it with objective criteria. This paper revised the text, utilizing by the Academy of Korean Studies, , and the by the National Institute of Korean Language to secure objectivity in revising the text.

We evaluated the inhibitory effect of Pueraria lobata root ethanol extract (PLREE) on lipid accumulation during 3T3-L1 differentiation to adipocytes by measuring the intracellular expression of adipogenic, lipogenic, and lipolytic markers and lipid accumulation. The total polyphenol and flavonoid content of PLREE were 47 and 29 mg/g, respectively. The electron donating capacity of PLREE at $1,000{\mu}g/mL$ was 48.8%. Treatment of 3T3-L1 preadipocytes with 100, 250, or $500{\mu}g/mL$ PLREE for 8 days dose-dependently promoted the differentiation of 3T3-L1 cells. In contrast, the lipid content of PLREE-treated cells was significantly reduced by 7.8% (p < 0.05), 35.6% (p < 0.001), and 42.2% (p < 0.001) following treatment with 100, 250, and $500{\mu}g/mL$ PLREE, respectively, as compared to differentiated control cells. PLREE upregulated peroxisome proliferator-activated receptor ${\gamma}$ mRNA and protein, and sterol regulator element-binding protein-1c mRNA levels, but did not affect CCAAT/enhancer binding-protein ${\beta}$ and ${\alpha}$ mRNA levels. PLREE also downregulated acetyl-CoA carboxylase mRNA and protein, fatty acid synthase (FAS) protein, and leptin mRNA levels, but did not affect FAS mRNA expression. PLREE upregulated adipose triglyceride lipase mRNA and protein expression, and hormone-sensitive lipase (HSL) protein expression, but did not affect HSL mRNA expression. In conclusion, we found that PLREE enhanced adipogenesis, but reduced lipogenesis, resulting in decreased lipid accumulation in 3T3-L1 cells.
