To this end, factor analysis, reliability analysis, and regression analysis was performed. A questionnaire was given to 374 cosmetology talent donors, and the results found the following: Personal competency revealed a highly significant correlation with talent donation, job commitment, and job satisfaction. However, for satisfaction with talent donation and job satisfaction, no considerable influence was found, even though they were partially significant. Furthermore, there was a highly significant correlation between job commitment and job satisfaction. It's been confirmed that participation in talent donation is influenced by the cosmetologists' personal competency. Therefore, this study proposed that it is a necessity to seek diverse options to enhance competency.

The aim of present study is to investigate antioxidative effect of the Rice Bran Extracts and Defatted Rice Bran Extracts. Rice Bran Extracts used Rice Bran Water Extract, Rice Bran Ethanol Extract, Defatted Rice Bran Water Extract, Defatted Rice Bran Ethanol Extract. This study was carried out to examine quenching effects of Rice bran extracts on DPPH-, Riboflavin-, and Xanthin oxidase- originated superoxide activities. In addition, in order to determine whether Rice Bran Extract can be safely applied to human skin, the cytotoxic effects of Rice Bran Extract in Human Dermal Fibroblast cells were determined using MTS Assay. These results demonstrated that RBE and DRBE had anti-oxidative properties and did not induce the cytotoxic effects in Human Dermal Fibroblast cells. Therefore, these findings suggest that anti-oxidative properties of RBE and DRBE may be considered convergence with skin care.

The purpose of this study is to determine the effect of the light-emitting-diode (LED) to investigate proliferation of human epidermal keratinocyte and collagen, procollagen expression. In order to determine whether LED irradiation can safely be applied to human skin, the proliferative effects of LED irradiation were determined by MTS assay in Human Epidermal Keratinocytes. Wavelength of 470nm LED irradiation increased mRNA expression of collagen, procollagen without cytotoxity. Our results suggest that 470nm LED irradiation may have a proliferative effects and collagen synthesis property. In order to determine whether LED irradiation can safely be applied to human skin, the cytotoxic effects of LED irradiation were determined by MTS assay in Human Dermal Fibroblasts (HDF). As far as we know, this is the first report demonstrating in vitro collagen synthesis activity of 470nm LED irradiation and being a scientific basis for the cosmetic.
