The purpose of this study is to compare the perceptions of hairdressers, hairdressers-to-be, and ordinary people on hairdressers. For this, 286 hairdressers, hairdressers-to-be, and ordinary people residing in Daegu and Gyeongbuk were surveyed and analyzed. The study results are as follows: First, the job preferred by hairdressers is running their own salon. Most of those involved in the beauty industry considered that anyone who has an aesthetic sense can become a hairdresser, the average education level is college, and 5-10 years of experience would be adequate. On the other hand, the majority of the ordinary people thought different. Second, most of the hairdressers thought that professional theoretical knowledge and skills are required for hairdressers and that they have the role of leading beauty. On the other hand, the majority of the hairdressers-to-be and ordinary people considered that what it takes to become hairdressers are design sense and creativity and that they should take the responsibility of cleanliness and service. Meanwhile, all the research subjects shared common ideas that the competence required for hairdressers is skills and female hairdressers are preferred. Third, the most common cause for hairdressers to move from a workplace to another was wage-related issues, and the most answered entry-level salary was between KRW 1 million and 1.5 million and average working hours a day 9-10 hours. Fourth, the research subject groups showed significant differences in their perception of the occupation of hairdresser. The results suggest that although the social perception of hairdressers is improving, ordinary people still need to change their perception.

In this study, we investigated the possibility of Kaempferia Galanga(KG) hot water extract on the antioxidant, cytotoxic and anti-inflammatory efficacy as a cosmetic ingredient. Antioxidant effects were evaluated based on DPPH and ABTS radical scavenging activity, FRAP assay, and total polyphenol contents. The MTT assay was used to confirm the cell toxicity in mouse macrophage RAW264.7 cells. Anti-inflammatory effects were also investigated in LPS-induced RAW264.7 cells by measuring secretion of NO, $TNF-{\alpha}$ and iNOS, $TNF-{\alpha}$ mRNA expression level. As a result, DPPH and ABTS radical scavenging activities were increased in a concentration-dependent manner. The ferric reducing antioxidant power(FRAP) was the highest at 5 mg/mL as 24.5 uM. The measurements of total polyphenol content was $1.28{\pm}0.064mg\;GAE/g$. The cytotoxicity of the KG extract results showed no cytotoxicity at concentration of 0.625 to 2.5 mg/mL. In addition, the extract of KG significantly suppressed the LPS-induced nitrite, $TNF-{\alpha}$ secretion and the mRNA expression of iNOS, $TNF-{\alpha}$ in RAW264.7 cells.
