  • The objective of this study was to compare antioxidant effects of different extracts of Salicornia bigelovii seed. DPPH radical scavenging activity, chelating activity of ferrous, superoxide anion radical-scavenging activity, hydroxyl radical scavenging activity, and contents of total polyphenol and flavonoid were measured for different extracts. Ethanol extract (10 mg/mL) was found to have the maximum DPPH radical scavenging and superoxide anion radical scavenging activities (65.26 and 62.36%, respectively). However, hot water extract (10 mg/mL) showed the highest hydroxyl radical scavenging and chelating activities (51.50 and 53.24%, respectively). Total phenolics and flavonoid contents in the ethanol extract were 522.8 and $480.35{\mu}g/mg$, respectively. They were 401.51 and $352.60{\mu}g/mg$, respectively, in the hot water extract. These results indicate that ethanol and hot water extracts of S. bigelovii seed have good potential to be used as a new source of antioxidants for functional foods, cosmetics, and pharmaceuticals.

  • The present study analyzed the tattoo image and body satisfaction according to the self-esteem. The samples were consisted of 191 female college students located in Kyunggi-do. The survey was implemented during may~july, 2012. Data were analyzed by frequency, factor analysis, cluster analysis, ANOVA, t-test, CPA, and Duncan-test. The results are as follows. Significant difference about tattoo image and body satisfaction was found in the group divided by the self-esteem. 'Individual personality' group had a tendency to be higher level than other group about appearance satisfaction and to be better image about Tattoo. 'Ego-centrism' group showed low level about good image of Tattoo. However, that group more satisfied their appearances than other groups. 'passive management' group showed lower level than other group about positive Tattoo image-building.

  • To estimate the inhibitory effect of Rubus coreanum extract on melanin biosynthesis, we tested its inhibitory effects on tyrosinase promoter in B16 mouse melanoma cells. Rubus coreanum extract by methanol had inhibitory effect approximately 10% on tyrosinase promoter at $100{\mu}g/mL$. In the MTT assay, the same extract exhibited very low cytotoxicity under $100{\mu}g/mL$. The fractions of methylene chloride, butyl alcohol and water did not showed the inhibitory effect on tyrosinase promoter, but the fraction of ethyl acetate exhibited inhibitory effect approximately 11% at $100{\mu}g/mL$.

  • This study aimed to observe the effects of Sea Buckthorn seed extracts (SEB) on anti-oxidation and antiinflammation. SEB were found to strongly depress ROS production depending on concentration, and 46.5% anti-oxidation effects were found in the top concentration of 100 ${\mu}g/mL$. Histamine and arachidonic acid release were measured to observe the effects of SEB on anti-inflammation. SEB inhibited histamine release and arachidonic acid release on dose dependent manner. Based on the results above, the conclusion is drawn that SEB have the potential to be used as natural materials that are effective for anti-oxidation and antiinflammation.

  • To investigate the effect of peanut sprout extract on skin care, we measured anti-oxidant activity and whitening action. As a result of measuring DPPH radical scavenging activity to examine independent anti-oxidation of peanut sprout extract, there was strongly scavenging activity. Fluorescent material DCF-DA was used to measure hydrogen peroxide created in RAW 264.7 cells, and all concentration dependently decreased ROS production. As a result of measuring nitric oxide to examine anti-inflammation of peanut sprout extract, there was strongly inhibited nitric oxide production in RAW 264.7 cells. Tyrosinase activation was found to inhibited dose-dependant. Melanin production was also prevented dose-dependant. Therefore, it is expected to be used effectively in development of functional cosmetic materials.

  • In this study, 340 Korean women were surveyed to analyze the impact of the type of sunscreen and use status on the satisfaction of products and resale. Studies have shown that indoor activity is higher than outdoor activity, and both simple and complex sunscreen is often used to compensate for skin tone. Out of single sunscreen, sun cream was used and air cushion was used a lot. Although product usability and UV protection indices were important factors in purchasing, 30% experienced side effects while product satisfaction and willingness to repurchase were high. The recognition of safety, Effectiveness, convenience, usability, satisfaction, and repurchase were all higher than that of composite UV-blocking products, and among subcomponents of product usage recognition, the level of convenience, efficacy, usability, and safety affected satisfaction and repurchase in order. Consequently, the perception of simple UV protection products was higher when using products for UV protection, and its convenience had a significant impact on satisfaction and resale.

  • This study attempted to investigate the value consciousness of purchasing behavior and purchasing intentions of personal beauty devices for women undergoing self-behavioral therapy. To this end, a survey was conducted, and a total of 342 copies of data were analyzed. As a result, In terms of the value consciousness, purchase behavior, and repurchase intention of the individual's personal beauty device, the value consciousness was the most materialistic, and the purchase behavior was the most economical. The overall repurchase intention was M=3.73 and SD=0.80. In correlations among value consciousness, purchase behavior and repurchase intention, positive correlations were confirmed (p<0.01). In terms of the influence of value consciousness on purchase behavior (aesthetics, conformity, effectiveness), 'aesthetic-pursuit factor' was the largest. In the effects of value consciousness on the economic aspect of purchase behavior, 'materialistic factor' was the highest. Lastly, in the influence of value consciousness on reliability, 'self-esteem factor' revealed the greatest effect. Furthermore, self-esteem factors had the biggest influence on repurchase intention. The above results confirmed that value consciousness of women in self-beauty care have a positive influence on their purchase behavior and repurchase intention for personal beauty devices. It is anticipated that they would be available as important marketing data in beauty device market.

  • The purpose of that was to investigate the potential of P. Herba extracts as phytonutrient active ingredients. In order to elucidate the P.Herba ethanol extracts were examined DPPH radical scavenging activity, NO production, protective effects against oxidative stress in HaCaT cells, anti-inflammatory activity, antimicrobial activity, anti-allergic effects, and inhibition of ${\beta}$-hexosaminidase expression. The antioxidative activity of the P. Herba extracts was compared, and the antioxidative activity of the ethanol extract was found to be superior. No significant cytotoxicity was observed in HaCaT, RAW 264.7, and RBL-2H3 cells. The protective effect of the extracts against oxidative stress induced by hydrogen peroxide ($H_2O_2$) was examined in HaCaT cells, and it was found to be 83% This concentration refers to which extract ethanol at $100{\mu}g/mL$. The anti-inflammatory activity of the extracts was examined in RAW 264.7 cells, and NO production was suppressed even at low concentrations. In addition, the concentration-dependent antimicrobial activities of the extracts were demonstrated in several bacterial strains, such as those of S.aureus, S.epidermidis and P. acnes. Based on the findings from this study, Portulacae Herba extracts could be used as physiological active substance that possess antioxidative, anti-inflammatory, and antimicrobial properties.
