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.

In the service industry the types are diversifying and the scale of service companies is greatly improving. Such a phenomenon is caused by economic growth and technological development diversifying consumer needs creating demand for new services maturing the service industry and intensifying competition among companies in the form of global competition. It can be said that this is because it is necessary to improve competitiveness by utilizing the economy of scale. Research is needed on the impact of entrepreneurship on various outcome variables in order for service organization managers to respond quickly to diverse and rapidly changing environments and achieve organizational outcomes and corporate goals of management outcomes. The purpose of this study was to empirically analyze the relationship in which the entrepreneurial spirit of a manager influences the relationship between customer orientation, which is an organizational result, customer satisfaction, and financial result, which is a management result. In order to verify such research, the questionnaire was composed of one business owner questionnaire, two employee questionnaires, and two customer questionnaires. The questionnaire was distributed to a total of 400 companies, and the questionnaires of 340 companies were collected. Of these, 303 companies, excluding the questionnaires of 37 companies with many dishonest or missing values, were used for hypothesis testing. The results of this study can be summarized as follows. First, entrepreneurship had a positive (+) effect on customer orientation, supporting the hypothesis. Second, customer orientation showed a positive (+) effect on customer satisfaction, supporting the hypothesis. Third, customer satisfaction showed a positive (+) effect on financial outcomes, supporting the hypothesis. Fourth, it was found that entrepreneurship influences customer satisfaction through customer orientation, and customer satisfaction affects financial outcomes. It turns out that customer orientation between entrepreneurship and customer satisfaction is completely mediated, and customer satisfaction is completely mediated by customer orientation and financial outcomes. The relationship between entrepreneurship and management improved employee behavior and attitudes, which is an individual outcome, and this change was found to improve customer satisfaction, which is an organizational outcome. It makes frequent contact with customers in the process of servicing them. Employee roles are important at service contacts and influence service purchases. Employees facing customers through service contacts act as a decisive factor in maintaining a continuous relationship with customers. Within a beauty service company, it is necessary to create a customer-oriented environment among workers. It suggests that customer-oriented companies and employees can anticipate their desires and provide products or services of superior value to achieve greater customer satisfaction and a competitive advantage. In addition, it was clarified that customer satisfaction has an aspect relationship with financial management, which is a management result. Therefore, it is suggested that the entrepreneurial spirit is an important factor for the management of a beauty service company to secure competitiveness and improve results.

온천수는 땅 표면에 자연 용출되거나 인공적으로 시추하여 끌어올린 지하수로서 수온이 그 지역의 연평균 기온 또는 그 지역의 얕은 지층의 지하수 수온보다 높아야 한다. 우리나라는 섭씨 25도 이상을 온천으로 규정하고 있다. 온천수는 일반적으로 혈액순환, 진통완화, 진정작용, 피부미용에 효과가 있는 것으로 널리 알려져 있으며 이것의 효능은 일반적으로 수온과 물속에 포함되어 있는 다양한 미네랄 성분의 작용으로 알려져 있다. 아산지역은 온양, 도고, 아산 온천으로 유명한 온천지대이다. 본 연구에서는 온천수를 화장품 제형에 적용시키고 피부자극테스트를 통하여 피부자극이 없음과 온양온천수를 이용한 제품에서 8.56%의 경피수분함유량의 증가가 나타나 피부개선 효과를 나타내었다.

본 연구는 피부미용전문가에 의한 관리 후, 홈케어 유무에 따른 건조피부의 개선 효과를 알아보고자 하였다. 건조피부로 평가된 10명을 대상으로, 한족 팔에는 마사지와 홈케어를 적용하고, 다른 쪽 팔에는 단지 마사지만을 적용하였다. 마사지는 호호바오일에 라벤더정유를 혼합하여, 10분간의 마사지를 주 2회로 총 4주 동안 실시하였고, 홈케어로는 마사지에서 사용한 시료를 집에서 매일 바르도록 하였다. 실험 결과 마사지와 홈케어를 적용한 그룹이 마사지만을 한 그룹보다 유분과 수분의 함유량이 증가하였다. 특히, 마사지와 홈케어를 한 그룹에서 마사지의 횟수가 증가 될수록 피부에서의 유 수분은 증가하는 것을 알 수 있었다. 따라서 전문가에 의한 관리효과를 유지하고, 더 효과적으로 건조증상를 개선시키기 위해서는 무엇보다도 홈케어의 중요성이 강조되어야 한다.

This paper investigates the insertion loss of nosie barrier with a intereference device. The efficiency of the conventional intereference-type noise barrier depends on specific frequency. Thus this study is performed to improve the efficiency of the rosie barrier in the range of broadband frequency, by changing the shape of intereference device and adding the channel with various depths. The boundary element method (BEM) is used to predict the insertion loss of noise barrier. (omitted)
