The purpose of the study is to provide information for developing beauty manager training programs. Samples consist of 248 hairdressers in Daejeon·Chungcheongdo. They participated in the study via questionnaire method. The data was analyzed through cross tabulation, multiple regression, One-way ANOVA on SPSS v. 21.0. The results were as follows. Firstly, regarding the demand of the beauty manager, 66.9% of the participants are in favor of having a beauty manager. Larger, franchise shops, and shops with higher profit are more aware of the need for beauty managers. Second, the survey showed that participants chose ‘boosting customer satisfaction’ and ‘improving effectiveness of employee performance’ as the top two roles and benefits of beauty managers. Third, while most participants answered beauty managers are needed for ‘improving effectiveness of employee performance.’ in general, employees answered that beauty managers are needed for ‘employee performance’ and shop owners chose ‘customer service.’ Lastly, 80.7% percent of participants showed high awareness toward the need for the training system for beauty managers. Respondents who showed high awareness in the role and the benefit of beauty managers showed higher awareness in the need for them also. The study found out that higher awareness in the role of beauty managers lead to higher awareness in the demand and need for them, which again lead to higher awareness in the need for education program for the beauty manager. It was also discovered that most participants only viewed the role and benefit of having beauty manager in restricted domains.

주주와 채권자 간의 이해상충에 관한 최근 연구는 경영진의 퇴직연금 둥 내부채권이 회사채나 은행대출에 비하여 만기가 길고 담보가 제공되지 않아 경영진에게 파산회피 유인을 제공함으로써 주주와 부채의 대리인 비용을 감소시킬 수 있음을 강조하고 있다. 본 연구는 내부채권으로 인한 경영진의 파산회피유인이 배당정책에 미치는 영향을 실증적으로 분석하였다. 분석결과, 경영진의 내부채권이 증가할수록 배당확률과 배당 수준이 모두 증가하는 것으로 나타났다. 또한, KZ 인텍스가 높은 기업은 배당이 감소 하지만 이와 같은 KZ 인텍스와 배당정책의 부(- )의 관계는 경영진의 내부채권이 증가할수록 현저히 약화되는 것으로 분석되었다. 본 연구의 분석결과는 경영진이 내부 채권을 보유한 기업은 긴축적 배당정책에 대한 필요성이 완화되며, 또한 재무제약으로 인한 배당감소유인 또한 완화된다는 것을 시사한다. Literature documents that executives`` inside debt holdings (debt-based managerial compensation) such as defined-benefit pensions and retirement funds are often unfunded and unsecured and have long maturities, and thus provide managerial incentives to pursue strategies to avoid the overall firm risk. This study investigates the effect of managerial inside debt compensation relative to equity-based compensation on a firm``s dividend payout policy. We find that a inside debt holdings are positively associated with various measures of a firm``s dividend payout policy. Additionally, we find empirical evidence in firms with inside debt holdings that the inverse relationship between high default risk measured by KZ index and dividend payout weakens as the portion of inside debt relative to equity-based compensation rises. This finding indicates that the needs for the firm to restrain dividend payouts to equity hoiders is reduced as the executive``s debt-to-equity compensation ratio becomes larger. Overall, the results suggests the mitigating effect of executives`` inside debt holdings on the conflicts between bondholders and shareholders can lead to generous payout policy.

Aminoglycoside antibiotics is an amorphous substance having excellent antimicrobial activity against Gram-negative and Gram-positive bacteria. Aminoglycoside antibiotics were used about 50 tons a year, it is one of the most commonly used antibiotics, along with penicillins, tetracyclines and sulfonamides. Despite their extensive use in livestock farming, the lack of data has led to any conclusions about the role of aminoglycosides in the environment. An analytical method was developed for the multi-residue determination of aminoglycosides. Sample preparation procedures were extraction with 10 mM Ammonium acetate/trichloroacetic acid buffer, followed by dispersive solid phase extraction cleanup, and analysis using liquid chromatography-tandem mass spectrometry. The proposed method was validated according to CODEX guidelines (CAC/GL-71-2009). Monitoring study was conducted on aminoglycosides antibiotics regulated in livestock and fishery products. We collected a total of 100 livestock and fishery samples (10 beef, 30 pork, 10 chicken, 10 milk, 10 egg, 10 flatfish, 10 eel and 10 shrimp) from the local market in south Korea. As a results, we detected the 4 aminoglycosides (Apramycin, streptomycin, dihydrostreptomycin, and neomycin) from the 11 samples (1 beef, 2 pork, 1 egg, 1 milk, 4 flatfish and 2 eel). But, all aminoglycoside residues were present at lower than the maximum residual limit. Therefore, it can be considered safe for the consumer use.

The research on character education has been actively done with an interest in character education, and teachers try to practice character education in school. Recently character education direction in Korea is to expand the hours of ‘character education’. The pan subject areas of national curriculum is added to ‘character education’, many programs for character education have been developed. Teachers take efforts to teach ‘character’ to students with a variety of theories and programs. However, since good character has made with one subject of ‘character education’, when character education is integrated with knowledge education in the whole process of education curriculum, students will grow up to be whole persons. This study is to learn character education from Rudolf Steiner’s anthroposophy in terms of Korea’s practice of character education. Steiner’s character education to be in harmony with the world will provide many implications in the practice of our character education.

오르프의 음악교육론

김유라(Kim, Yu-Ra) 한국교육철학회 2013 교육철학 Vol.49 No.-

The purpose of this study is to understand the music education doctrine of Carl Orff in a view of modem inheritance of Jean-Jacques Rousseau's the natural music education doctrine. Orff is an acknowledged 20th century's German music educator. Orff’s influential teaching approach has still been researched around the world, including United States, Asia, and Europe, as well as implemented in the field of education. Orff’s teaching approach has opened a new era for music education with a method never been used before. That is the reason Orff’s music education is widely studied beyond his time. Orff suggested the music education for children with detailed ideas and implemented child-centered music education. Orff’s education is influenced by Rousseau's child-centered approach and has a foundation of the naturalism. 111e purpose of Rousseau's education is to raise a natural human being by promoting a child's natural abilities, which is the basic of the doctrine. Also, Rousseau's music education is deeply involved with this view of nature which is its origin. The pursuit of nature-congruent music education is about seeking a simple and natural life in compliance with the laws of nature. This perspective is presented well on Rousseau's educational view of music which is about a simple melody, sensory training, musical expression from inside, respect for creativity, and discovery of a self-song. Orff’s music education has a foundation of naturalism, called 'Elementary music'. It says: music has to be simple and easy so that every child plays and enjoys; also, music education should be complied with the laws of nature to meet the developmental stages of their own; children need to discover and develop their own world of music; music classes should be the time to learn the true fun of it, not to learn music for a study; this can inspire children's own creative musicality; music activity does not necessarily require musical talent to be a subject of music. It shows that Orff’s music education has been understood and implemented in same terms of Rousseau's. Understanding Orff’s doctrine is helpful to learn the implications of how to practice child-centered music education.

이익투명성이 기업가치에 미치는 영향: 기업지배구조 특성별 차이를 중심으로

김유라(Kim, Yu-Ra),오현민(Oh, Hyun-Min),신호영(Shin, Ho-Young) 글로벌경영학회 2018 글로벌경영학회지 Vol.15 No.3

본 연구에서는 이익투명성이 기업가치에 미치는 영향과 기업지배구조 특성별 차이에 따른 이익투명성이 기업가치에 미치는 영향을 살펴보고자 한다. 이익투명성이 높을수록 기업가치는 향상될 것으로 예측된다. 이는 선행연구를 바탕으로 다음과 같은 세 가지 관점에서 논의될 수 있다. 첫째, 자본비용의 감소로 수익성이 증대될 것이다. 둘째, 정보비대칭과 대리인비용 감소로 신뢰성 있는 투자기회 및 투자효율성 증가로 이어질 것이다. 셋째, 상대적으로 높은 감사품질을 갖기 때문에 이익조정 가능성이 감소하고 이익의 질이 향상되어 기업가치가 향상될 것이다. 이익투명성의 측정은 Cheng and Subramanyam(2008)의 방법론을 사용하였고, 기업가치 평가는 토빈Q를 사용하였다. 분석기간은 2011년부터 2017년까지 유가증권시장에 상장된 비금융업 12월 결산법인을 대상으로 하였다. 연구결과는 다음과 같다. 첫째, 이익투명성과 기업가치는 양(+)의 상관관계로 나타나 이익투명성이 높을수록 기업가치가 향상된다고 해석된다. 둘째, 기업지배구조 변수로 다섯 가지를 이용한 결과 최대주주지분율이 낮을수록, 대규모기업집단에 소속될수록, 사외이사비율과 이사회 규모가 클수록, 외국인지분율이 높을수록 이익투명성으로 인한 기업가치 효과는 증가하였다. 다만, 최대주주지분율은 통계적으로 유의하지 않았다. 본 연구결과는 회계투명성과 기업가치가 비례적 관계라는 기존 선행연구와 같은 맥락에서 이익투명성이 회계투명성 설명변수의 하나로 사용될 수 있다는 주장을 지지한다. 또한 우수한 기업지배구조를 가질 때 이익투명성이 기업가치에 미치는 긍정적인 영향을 더욱 강화하는 효과가 있다는 실증결과는 국내 기업의 이익투명성 관리를 더욱 촉진시킬 것이다. 무엇보다 연구의 주요 가설을 토대로 투명한 이익정보에 따른 주가가 기업의 실질적인 내재가치 평가에 기여할 것이다. The issues of accounting transparency have been dealt significantly by the accounting association. In Korea, because of the foreign exchange crisis in the late 1990s, accounting transparency issues have become important to enterprises, the expansion of the stock market and the use of K-IFRS have proved it already. However, despite of the growth of Korean companies and accounting systems, the IMD(International Institute for Management Development) ranked Korea as the lowest among 61 countries surveyed in the accounting transparency category in 2016. To guarantee accounting transparency to overcome this problem is a very emergency task because it is closely related to economic growth. Therefore, this paper studies the subject of earnings transparency. This study examines the effect of earnings transparency on the firm value and also the differences of the impact by corporate governance characteristics. In this study, earnings transparency is proxied by measures developed by Cheng and Subramanyam(2008) and firm value proxied by Tobin s Q. The sample consists of firm-year which has December fiscal year-end and listed on the securities market over 2011-2017. Empirical results are as follows. First, earnings transparency is significantly and positively associated with the firm value. This means that higher the earnings transparency is, the greater the firm value is. Second, this study finds that the firm value increased on the earnings transparency when firms with business group affiliation, outside director system and board size, foreign ownership ratio are high. Non-significant results are observed when the largest shareholder ownership ratio are low. This results support some arguments that earnings transparency can be used as one of the explanatory variables for accounting transparency. Our research findings will facilitate the management of earnings transparency in domestic enterprises and contribute to the practical assessment of the company s intrinsic value.

펀 디자인: 행동변화와 소셜 인터랙션을 위한 핵심요소 분석 - 사회적 디자인 사례들을 중심으로 -

김유라 ( Kim Yu-ra ),이선민 ( Lee Sun-min ),강부경 ( Kang Bu-kyung ),윤재영 ( Yun Jae-young ) 커뮤니케이션디자인학회(구 시각디자인학회) 2017 커뮤니케이션 디자인학연구 Vol.61 No.-

‘재미(Fun)’적 요소가 더해진 제품과 서비스, 캠페인은 사용자들에게 신선한 경험과 즐거움을 제공하며 사용자들의 긍정적 반응 및 행동을 이끌어 낸다. 이는 수익성에만 그치는 것이 아니라 공익성까지 이끌어 내는 결과로 이어진다. 본 연구에서는 사회적 디자인 사례 분석을 통해 사용자의 행동변화를 유도하는 ‘펀 디자인(Fun Design)’의 정의와 핵심요소에 대해 이야기한다. 펀 디자인의 핵심요소는 크게 세 가지로, ‘트리거(Triggers)’, ‘피드백(Feedback)’, ‘소셜 인터랙션(Social interaction)’이 있다. 트리거는 매체의 유형과 시청각적 요소들로 이루어져 있으며, 피드백은 비물질적 피드백과 물질적 피드백으로 구분된다. 분석 결과 트리거는 사용자의 호기심을 유발하여 자발적 참여와 행동을 이끌어 내는 역할을 하였고, 피드백은 행동에 대한 보상인 동시에 지속적인 행동을 유도하는 것으로 나타났다. 소셜 인터랙션은 펀 디자인이 감정적 맥락에서의 재미 뿐 아니라 사회적인 맥락 안에서 사용자 간의 소통과 상호적 관계를 형성한다는 점에서 의미가 있다. Recent products, services and campaigns combined with “fun” elements are providing a new experience and enjoyment for many users, drawing further positive behavior and response. The results of such participation and behavior extend beyond profitability, effectively promoting the public interest. We defined and analyzed key elements of “Fun Design” through fifteen social design cases that induce optimistic changes in people’s behavior. In this study, we highlight three major elements: triggers, feedback, and social interaction. Triggers consist of a medium, visual and/or auditory elements, whereas feedback can be categorized into either non-material or material. Our results indicate that although triggers first stimulate one’s interest and curiosity to take actions, feedback, which is given in reward for one’s behavior, appears to be a more significant factor in maintaining that behavior. Social interaction, in particular, is meaningful because it makes Fun Design effective in creating interactive relationships between individuals within the social context.

Large cell neuroendocrine carcinoma of the uterine cervix is a rare and highly aggressive cervical neoplasm. Metastases and recurrences of the tumor are common. Cervical large cell neuroendocrine carcinomas are distinctive cervical carcinomas that are frequently misdiagnosed and have unfavorable prognosis. So prudential care must be considered for proper diagnosis and multimodal treatment may be required for better survival. We experienced one case of large cell neuroendocrine carcinoma accompanied with adenocarcinoma of the uterine cervix in 52 year old woman. The uterine cervix covered and infiltrated with adenocarcinoma cells and attached polypoid mass (3.2×2.1 ㎝) composed of large cell neuroendocrine carcinoma cells. The diagnosis was confirmed by immuno-staining using cytokeratin (+), synaptophysin (+), chromogranin (+), neuron-specific enolase (+), CD 56 (+), and vimentin (-). So we report the case with brief review of the literature.

슈타이너의 인지학에 기초한 발도르프교육이 한국의 생태유아교육에 주는 시사점 고찰

본 연구는 생태유아교육과 슈타이너의 인지학에 기초한 발도르프교육의 공통점을 이해하고 차이점을 살펴봄으로써 발도르프교육이 생태유아교육에 줄 수 있는 시사점을 알아보려는 것을 목적으로 한다. 공통적으로 생태유아교육과 발도르프교육은 산업시대의 물질만능주의와 인간소외, 그리고 생명파괴의 문제를 극복하기 위한 대안적인 교육으로서 성격을 갖고 있어 자연과 삶을 체험하는 프로그램을 운영하는 등 교육방법 및 내용에서도 이들 간에 공통점이 나타나고 있다. 슈타이너 인지학과 그에 기초한 발도르프교육은 인간본질에 대한 이해로부터 발달단계를 설정하여 유아교육에서부터 초중등교육에까지 지속되는 체계적인 교육과정을 제시하고 있다. 생태유아교육역시 유아교육에서부터 초중등교육을 포함하는 체계적이고 연계성 있는 교육과정을 운영하는 것이 중요할 것이다. 이러한 점에서 인간에 대한 본질적 이해로부터 학습원리와 방향을 제시하는 슈타이너의 인지학내 기초한 발도르프교육은 생태유아교육이 체계적인 교육과정을 구성하고 교과교육과 연계하는 방법을 마련하는 데 시사점을 줄 수 있을 것으로 생각된다. This research aimed at investigating the implication of Waldorf education on eco-early childhood education by understanding common ground between eco-early childhood education and Waldorf education based on Steiner`s anthroposophy and exploring the difference. Commonly, eco-early childhood education and Waldorf education have the characteristic of alternative education to overcome mammonism, human alienation of industrial era, and the problem of destruction of life, therefore, there are common points between them in respect of educational method and content, e.g. operating the program to experience the nature and the life. Steiner`s anthroposophy and Waldorf education based on that suggest systematic educational process which is continued from the early childhood education to the elementary and middle school education, by establishing developmental stage from the understanding of human essence. Eco-early childhood education, also, it is important to operate a curriculum which is systematic and connective, including from the early childhood education to the elementary and middle school education. In this regard, the researcher considers that Waldorf education based on Steiner`s anthroposophy, which suggests the essential understanding of human, leaning principle and direction can give an implication on eco-early childhood education to compose systematic curriculum and prepare the method to connect to curriculum education.

This study attempted to investigate the possibility of using Muunsan extract as a new natural cosmetic ingredient by preparing a hair conditioner containing such an extract, applying it to permed hair, and analyzing its effects with the goal remedying subalhwangrak (yellowish and gray hair losing gloss and smoothness) as defined in oehyeongpyeon (external medicine) of the Donguibogam (Korean medical encyclopedia). According to measurements, ‘V’ was the greatest, followed by ‘C-2’, ‘C-1’, ‘B-2’, ‘A-2’, ‘B-1’, ‘A-1’, and ‘C’ in terms of hair thickness and tensile strength. In other words, ‘C-2 (hair post-treated with a hair conditioner containing Muunsan extract)’ was the best, following only virgin hair in terms of hair thickness and tensile strength. In terms of absorbance, ‘C’ was the highest, followed by ‘A-1’, ‘B-1’, ‘A-2’, ‘B-2’, ‘C-1’, ‘C-2’ and ‘V’. In other words, ‘C-2’ was the lowest, following only virgin hair in terms of the damage index. According to the analysis of cuticle with SEM(Scanning Electron Microscope), scales were most firmly adherent to the scalp and associated hair in ‘C-2’ as exfoliation and unevenness were low. When essential hair components were analyzed by EDS(Energy Dispersive X-ray Spectro mrtry), ‘V’ was the highest with 6.37%, followed by ‘C-2’, ‘C-1’, ‘B-2’, ‘B-1’, ‘A-2’, ‘A-1’ and ‘C’ n terms of sulfur (‘S’) content. The above results proved the hair protection effects of Muunsan extract and confirmed that it would be viable as a new ingredient for hair cosmetics.
