Since the introduction of a new field of skin care to Korean market which was developed in 1980, a variety of skin care therapies have appeared in mid-1990s. Therefore, in particular, it is considered that aromatherapy is one of the most preferred methods for skin care. Therefore, previous studies focused just on clinical effects of aromatherapy while this study focuses on aestheticians by identifying whether performance of aromatherapy, and their contribution to income will influence on satisfaction in aestheticians and customers' intention to reuse aromatherapy service for positive demonstration. The results of the study are presented as follows: First, it is demonstrated that side-effect of aromatherapy, contribution to income, and customer satisfaction have significant effect on professional aestheticians. In particular, in respect to the aestheticians, this study obtains the results rather different from the estimation that customers are satisfied with the professional service though they have side-effect. Second, as the satisfaction in professional aestheticians after skin care service is a significant factor that influences on intention to reuse it, this study concludes that re-management on behaviors is required according to the degrees of satisfaction.

To show the anti-oxidation effects of Phragmitis rhizoma extract, this study investigated the composition ratio of its components, thecontent of the anti-oxidative materials polyphenol and flavonoid, and the DPPH scavenging effect and SOD activity to measure anti-oxidative activity. It was shown that P. rhizoma is composed of the following: 77.88% natural fiber, 9.15% moisture, 6.62% protein, 5.95% minerals ash, and 0.40% natural fat. The content of polyphenol in the hot water extract was 4.59±1.60mg/g and 10.13±1.81mg/gin the ethanol extract, and that of flavonoid in the hot water extract was 26.76±0.55mg/g and 28.65±1.45mg/g in the ethanol extract. Therefore, in P. rhizoma extract, the content of flavonoid was higher than that of polyphenol and that of the anti-oxidative matter in theethanol extract was higher than that in the hot water extract. The DPPH scavenging effect of P. rhizoma ethanol extract was 75.17±0.68% at 10.0mg/ml while that of hot water extract was 52.33±0.48% at the same concentration, which indicates that of the ethanolextract was higher than that of the hot water extract. It was discovered that the content of SC50 in the hot water extract was 0.939mg/ml,0.497mg/ml for the ethanol extract, and contained 0.062mg/ml of ascorbic acid. This indicates that the P. rhizoma ethanol extract has ahigher anti-oxidation activity than other natural materials although it has slightly lower activity than ascorbic acid. With respect to theSOD-like activity of P. rhizoma, the ethanol extract was 27.32±1.44% in 10.0mg/ml and the hot water extract was 18.84±1.78%, whichmeans that the SOD-like activity of the ethanol extract of P. rhizoma was also higher. As a result of this study, it was discovered that theanti-oxidative activity of the ethanol extract was higher than that of the hot water extract, and the degree of its anti-oxidation is relativelyhigh. Therefore, it is suggested that P. rhizoma extract has high value as a material for functional cosmetics.

현대사회의 여성들의 역할과 지위는 점점 높아지고 있으나 결혼과 동시에 임신, 출산, 육아 등의 이유로 남성과 달리 경제활동을 중단함으로써 경력단절을 겪게 되는 것이 현실이다. 따라서 본 연구에서는 뷰티 관련 직업교육 프로그램에 참여하고 있는 경력단절 여성을 대상으로 경력단절 기간에 따라 재취업에 대한 취업선택 동기 및 취업준비 행동이 재취업에 미치는 영향을 파악하여 직업교육의 실증적 검증으로 검증하고자 한다. 연구대상은 광주⋅전남지역에 거주하는 경력단절 여성으로 설문조사를 실시하였으며, 윈도우용 SPSS 21.0 통계 패키지를 이용하여 빈도분석, 기술 통계분석, 요인분석, 신뢰도 분석, 구성개념 변수들의 유의한 상관관계를 나타내는 상관분석, 회귀분석을 실시하였으며 연구결과는 다음과 같다. 첫째, 경력단절 기간에 따른 뷰티관련 재취업의사의 차이를 살펴본 결과 경력단절 기간에 따라 유의한 차이가 나타났으며, 단기간(1년 미만),이 가장 높고, 장기간(3년 이상), 중기간(1년-3년 미만) 순으로 나타났다. 둘째, 뷰티관련 직업훈련교육에 참여하고 있는 경력단절여성의 취업선택 동기가 재취업의사에 미치는 영향을 분석한 결과 다소 차이가 있음을 확인할 수 있었다. 1년 미만의 경력단절 여성은 개인적 동기(β값=.328, t값=3.601, p<.001)가, 3년 이상 경력단절 여성도 개인적 동기가(β값=.625, t값=5.644, p<.001) 긍정적 영향을 미치는 것으로 나타난 반면 1년-3년 미만의 경력단절여성의 경우는 사회적 동기측면이 재취업의사(β값=.350, t값=2.191, p<.05)에 긍정적 영향을 미치는 것으로 나타났다. 셋째, 경력단절기간에 따른 취업준비행동이 재취업에 미치는 영향을 살펴본 결과 단기 경력단절 여성의 경우 단기간의 경우 취업준비행동을 제외한 계획(β값=.278, t값=3.302, p<.01), 준비(β값=.224, t값=2.557, p<.05), 기대(β값=.362, t값=4.194, p<.001)가 취업의사에 긍정적 영향을 미치는 것으로 나타났다. 그러나 중 기간 경력단절여성의 경우 기대(β값=.296, t값=2.062, p<.05)만이다. 따라서 경력단절 여성의 경우 단절 기간에 따라 재취업에 미치는 영향이 다소 차이가 있어 훈련 프로그램을 구성하는 경우에 조직적 차원에서 기간을 고려하여 프로그램을 운영한다면 더 좋은 성과를 가져올 수 있을 것으로 사료된다. Although positions of women in modern society are getting higher, as their economic activities are interrupted due to pregnancy, child delivery and nursing, their career discontinues Therefore, this study aimed to identify the effects of job selection motives and employment preparation behaviors on reemployment according to career discontinuity periods in career discontinuity women who were participating in a beauty-related job education program and provide basic data for development of employment support programs along with experimental demonstration of jon education. The subjects of this study were career discontinuity women who were living in Gwangju and Jeonnam and they were surveyed with a use of a questionnaire. Using SPSS 21.0, this study conducted a frequency test, a descriptive statistical test, a factor analysis, a reliability test, a correlations analysis that indicates significant correlations between variables of constructs and a regression analysis, and the results are presented as follows: First when this study investigated beauty-related reemployment intention according to career discontinuity periods, there was a difference according to the period and the intention was the highest in a short period (below 1 year of career discontinuity), followed by a long period(above 3 years) and then an intermediate period(1 to 3 years). Second, when this study analysed the effects of job selection motives of career discontinuity women who were participating in beauty-related job education on reemployment and business inauguration intention, it was discovered that there was a difference. For both the subjects who discontinued career for below 1 year and above 3 years personal motive (β value=.328, t value=3.601, p<.001 and β value=.625, t value=5.644, p<.001) had positive effects, but for those who discontinued career for 1 year to below 3 years, social motives had positive effects on reemployment intention (β value=.350, t value=2.191, p<.05). Third, when this study investigated the effects of employment preparation behaviors on reemployment, it was discovered that as for the subjects who discontinued career for a short period, it was discovered that except employment behaviors, plans(β value=.278, t value=3.302, p<.01), preparation(β value=.224, t value=2.557, p<.05), expectation(β value=.362, t value=4.194, p<.001) had positive effects on reemployment intention. However, forr those who discontinued career for an intermediate period, only expectation (β value=.296, t value=2.062, p<.05) had significantly positive effects on reemployment intention. Therefore, as career discontinuity periods of women had different effects on reemployment, if organizations develop education programs in consideration of periods, it is assured that results will be better.

Creatures in the earth maintain their constancy and circadian rhythm in biochemical, physiological and behavioral metabolic process. Part of oxygen in human bodies forms free radical generated from chemical reaction and when it is generated excessively, it may be reasons of all diseases. Therefore, this study aims to analyse components of dried and fermented Salicorinia herbacea to discover the antioxidative effect using DPPH and evaluate their efficacy as biologically active substance. As a result of the proximate analysis, 24.19% of crude fiber, 16.15% of crude ash were found in dried S. herbacea, and 67.36% of crude ash was found in fermented S. herbacea. For total phenol contents, dried S. herbacea has 19.28 mg/g of polyphenol and 61.80 mg/g of flavonoid while fermented S. herbacea has 19.28 mg/g of polyphenol, 70.95 mg/g of flavonoid. DPPH scavenging activities of dried S. herbacea were 10.48, 19.38, 31.08, 57.69, and 87.9% in 0.0625, 0.125, 0.25, 0.5, and 1 mg/mL of dried S. herbacea while DPPH scavenging activities of fermented S. herbacea were 23.61, 45.06, 70.75, 90.41, 91.04%. SC50 of dried S. herbacea was 4.28 mg/mL, and SC50 of fermented S. herbacea was 1.49 mg/mL. As a result, fermented S. herbacea had higher phenol contents and antioxidative effect than dried S. herbacea. Therefore, it was discovered that it can be applied for internal and external medicine and cosmetic materials as an antioxidant which can enhance curing ability of damaged tissues against free radicals.
