The backs with a hair cut of 6-week-old healthy ICR male mice were once exposed to a dose of 400mJ/cm2UVB. An acute dermal inflammation was observed, and the inflamed skins were almost completely cured after6 days of the exposure. At 24 hours after exposure, the epidermal keratinocytes showed a cell-membranedamage with the destruction of intercellular junctions, agglutination of tonofilaments within the cytoplasm andnucleus damage. The activity of XO showed a significant increase(p0.05) in up to 144hours. The activitiesof CAT and SOD showed a significant decrease (p0.05) in up to 96 hours, but they were not significantlydifferent from the normal value at 144 hours. The GST activity was significantly decreased(p0.01) in up to96hours, not so at 24hours. However, that was not significantly different from the normal value at 144hours.There was a significant decrease (p0.01) in the contents of TBARS at 48 and 96 hours, without anysignificant difference at 144 hours. While the content of GSH was significantly lower (p0.05) at 24 hours,that was not significantly different thereafter up to 144 hours from the normal value. Therefore, it is assumedthat skin damage with a dose of 400 mJ/cm2 UVB irradiation might be caused by the oxidative stress whichwas resulted from the unbalance of oxygen free radical generating and scavenging enzymes.

예술단 리더의 서번트 리더십이 관계품질, 고객지향성, 공연성과에 미치는 영향에 관한 연구

이승자,차민석 리더십학회 2019 리더십연구 Vol.11 No.1

Arts have characteristics that lead to production and consumption at the same time same as other services. Therefore, for the successful art performance, it is essential to form a program for customer satisfaction. In addition, relevant leadership is required to enhance cooperation and customer orientation of the arts members. Thus, the purposes of this study are to investigate the effects of artistic leaders’servant leadership on the relationship quality, customer orientation and performing performances. Servant leadership seems to have positive effects on the relational quality with the leader, that would be closely related to customer orientation and performing performance. In order to verify these hypotheses, the measurements are selected based on the previous research. A total of 400 questionnaires were distributed from April to May 2019 for musical artists belonging to Kyungnam Regional Performing Organizations, and 276 responses were finally analyzed as a sample. The results showed that servant leadership positively affected relational quality composed of trust and commitment. This result is consistent with the previous studies that servant leadership helps to enhance members’trust and commitment to leader. The trust and commitment enhanced customer orientation as well as the performing performance. These results implies that the leader of art organization should consider and develop the components of the servant leadership such as responsible person consciousness, growth support, community formation and vision presentation. The result suggests that those factors of servant leadership and relational qualities of trust and commitment leads to customer orientation and performing performance. So, leaders of the performing organization should consider those critical factors to be developed for improving customer orientation and performing performances. Key words: Servant leadership, Leader Trust, Relational Quality, Customer orientation, Performing Performance, Performing Arts Organization 본 연구는 예술단 리더의 서번트리더십이 예술단원들과의 관계품질 및 고객지향성과 공연성과에 미치는 효과를 파악할 목적으로 수행되었다. 예술 공연은 생산과 동시에 소비로 연결되는 특성을 가지고 있다. 따라서, 성공적인 공연을 위해서는 고객 만족을 위한 프로그램의 구성이 필수적이다. 고객 만족지향성을 높이기 위해서는 예술 단원의 협력적 관계가 필요하다. 단원 간의 관계결속을 위해서는 예술단 리더의 적절한 리더십이 요구된다. 예술단 리더의 리더십이 권위주의적 방식에서 섬김의 서번트리더십으로의 전환에 대한 검토가 필요한 시점이다. 서번트 리더십이 과연 예술단단원들 간의 관계품질에 긍정적인 영향을 주는지, 단원간의 관계품질이 고객지향성과 공연성과과의관계는 어떠한지를 실증적으로 살펴보았다. 본 연구에서는 관련된 가설들을 제시하고 검증하기 위하여 선행연구를 토대로 변수별 측정문항을 선정하여 설문조사를 진행하였다. 경남지역 연주단체에속해있는 음악 예술인을 대상으로 2019년 4월부터 5월까지 총 400부의 설문지를 배포하여 최종적으로 276부의 설문지를 응답받아(응답율 69%) 표본으로 확보하였다. 통계분석을 수행한 결과 서번트리더십은 관계품질의 구성요인인 신뢰 및 결속에 긍정적인 영향을 주었으며, 관계품질의 신뢰와결속은 고객지향성을 높이는 것으로 나타났다. 특히, 리더와의 결속은 공연 성과에 직접적인 영향을주었다. 이러한 결과는 구성원들의 성장을 돕고 지원하는 서번트리더십이 구성원들의 리더에 대한신뢰와 결속을 높이는데 도움을 준다는 선행연구와 일치하며, 예술단 표본에서도 일관된 실증결과를 얻을 수 있었다. 또한, 예술단의 경우에는 책임자 의식, 성장지원, 공동체 형성, 비전제시 등과같은 서번트리더십의 하위 구성요소들을 고려하여 예술단을 운영할 필요가 있으며, 단원들의 관계결속과 함께 고객지향성을 향상시켜야 성공적인 공연성과를 올릴 수 있음을 시사하고 있다. 키워드: 서번트 리더십, 리더 신뢰, 관계 결속, 고객지향성, 공연성과, 예술단

This study performed a self-administered questionnaire survey among a total of 320 college women in Gyeonggido and Gangwon-do to analyze characteristics of the occurrence of acne and investigate correlations among facewashing and overall experiences with acne, living habits, and cosmetics. SPSSWIN 18.0 was utilized for data analysis, frequency analysis, multiple-response analysis and crosstab analysis. Results are as follows: in terms of acne experience, ‘currently suffering from acne’ or ‘had acne before, but not anymore’ were the most prevalent responses, accounting for 88.2% in ‘age 19 – under 20’, followed by ‘age 25 or older (69.7%)’. Regarding lifestyle habits of those who are suffering (or suffered) from acne, ‘less than 7 hours' was the most common response returned for sleep duration. In terms of dietary habits, ‘mostly meat’ and ‘wheat flour and fried dishes’ were most commonly selected (85.3%). When asked where acne most often occurs, ‘forehead, cheek, nose’ were the most frequent responses (67.1%). In terms of acne type, ‘slightly reddish acne’ was the most common response (56.9%). In terms of relevance between acne experience and family history, ‘sibling with a similar lifestyle’ was the most frequently selected response (p<0.01). Regarding relevance between acne experience and use of cosmetics, those who had acne before (33.8%) were more abundant than those with no acne experience (16.7%) in terms of the use of cosmeceuticals (acne, atopic dermatitis, etc.) with statistical significance (p<0.01). Concerning relevance between acne experience and face washing, those who had acne before (3 times or higher, 22.7%) accounted for a greater amount than those with no acne experience (10.0%) in terms of face washing frequency (p<0.05).

니체와 다석 유영모의 밥 철학으로 조명하는 빈부의 양극화해소, 삼투작용의 길

이승자 한국외국어대학교 철학과문화연구소 2010 철학과 문화 Vol.20 No.-

21세기 자본주의의 총아, 물질과 소비만능을 선동하는 넘치는 풍요로부터 소외된 절대빈곤층의 점증적 증가와 날로 틈이 벌어지고 있는 빈부의 양극화 현상으로 인하여 점점 고조되고 있는 사회적 강등. 그 원인은 당연히 부의 편중과 올바른 나눔의 결여다. 공생공존의 차원에서 이는 반드시 극복되어야 할 현실이다. 그렇다면, 극복을 위한 새로운 처방전은 무엇일까? 당연히 올바른 나눔의 정신이다. 올바른 나눔의 정신이란 자본주의가 안고 있는 자본에 의한 약육강식을 지양하여 약자도태를 막기 위한 상생의 정신뿐이다. 이 같은 상생의 정신을 밥이 궁하지 않은 시대에 밥이라는 단어로 상징화하여 재인식을 촉구한다. 왜냐하면, 절대빈곤의 문제란 곧 가장 일차적으로 밥의 문제이기 때문이다. 그 재인식을 위하여 밥에 관한 한 서로 상반된 사상을 보여 주고 있는 니체와 다석 유영모 선생님의 밥 철학을 방법론적으로 초대한다. 그 이유는 전자는 반 그리스도적으로서 사회적 적자생존을 암암리에 선동하고, 후자는 그리스도적으로 절대빈곤층인 약자도태를 적극 지양(止楊)하며 적자와 약자의 공생공존을 지향하고 있다는 평가에 따른 것이다. Ist es nicht eine Krise, dass der Abstand zwischen Reichtum und Armut immer größser wird in diesem 21. Jh., das als die reichste Epoche der gesamten Menschheitsgeschichte eingeschätzt wird? Die Ursache dafür ist das Übergewicht des Reichtums und der mangelnde Geist zu verteilen. Dies muß überwunden werden, um koexistieren zu können. Sonst eskaliert diese Krisensituation. Aber wie kann dieses Phänornern überwunden werden? -Indem wir alle den gerechten Geist zu verteilen erkennen. Was ist dieser gerechte Geist zu verteilen? - Das ist nicht nur das Erkennen sondern auch Anerkennen der Koxistenz, um z. B. die Entlassung der Schwachen zu verhindern. Denn Kapitalismus bedeutet, dass der Schwächere dem Kapital des Stärkeren zum Opfer fällt. In dieser Situation versucht der Artikel, eine mögliche Lösung dieser Krise zu finden. Um dieses Ziel zu erreichen, werden zwei Philosophen eingeladen: Friedrich Nietzsche und der koreanische Philosoph Jou-Jungmo Daserk. Der Grund für die Auswahl dieser beiden besteht darin dass ietzsche als Antichrist das Schwachsein des Opfers kritisiert und im Gegensatz dazu Daserk als Christ an die Koexistenz und die gerechte Verteilung appelliert. Methodisch wird von beiden eine Brot-Theorie benutzt, weil Brot das eingentliche Problem für Armut ist. Natürlich kann man bei Nietzsche eine Brot-Theorie nicht direkt finden, sondern nur im übertragenen Sinn. Aber bei Daserk kann man durchaus von einer Brot- Philosophie sprechen.
