The aim of this investigation was to examine the antioxidation, physicochemical, and sensory activity of a Korean steamed-rice cake, Sulgidduk, fortified with water extracts from Moringa oleifera (M. oleifera) leaf. M. oleifera leaf extracts were added to rice powder at rations of 0.1%, 1% and 10%. To examine antioxidation properties, the scavenging activities of DPPH radicals, hydroxyl radicals, ABTS+ radicals, and ferric ion reducing antioxidant power were investigated. M. oleifera extracts significantly increased the antioxidation activities of Sulgidduk in a dose dependent manner (p<0.05). Physicochemical characteristics were measured by proximate composition, color, texture profile analysis, and sensory evaluations. As the concentration of M. oleifera leaf extracts increased, L-values and a-values significantly decreased while b-values increased. Texture profile analysis demonstrated that the control groups showed significantly higher values for hardness, cohesiveness, chewiness, and adhesiveness as compared with groups containing M. oleifera leaf extract (p<0.05). In the sensory evaluation, the sample containing 0.1% of M. oleifera leaf extract obtained the best results in overall preference. Taken together, these results suggest that M. oleifera leaf may have the potential to increase the consumer acceptability and the functionality of Sulgidduk.

Quality Factor: 교수연구업적평가를 위한 새로운 계량 지표

최은주,양기덕,이혜경,Choi, Eun-Ju,Yang, Kiduk,Lee, Hye-Kyung 한국도서관정보학회 2016 한국도서관정보학회지 Vol.47 No.1

본 연구는 교수의 연구업적을 보다 다면적으로 측정하기 위한 합리적 방법을 고안하기 위하여 새로운 논문계량지표인 Quality Factor를 개발하였다. Quality Factor는 총 논문수, 피인용수, h-index, Impact Factor를 이용하여 수치를 도출한다. 새로 개발한 지표인 Quality Factor와 다양한 지표(논문 수, Impact Factor, 피인용수, h-index, g-index)간의 관계를 분석하기 위하여, 본 연구는 국내 문헌정보학과 교수 189명의 14년간(2001-2014)의 학술논문데이터를 바탕으로 그들의 지표별(논문 수, Impact Factor, 피인용수) 순위를 산출하고 지표들 간에 스피어만 순위상관관계를 도출하였다. 그 결과, Quality Factor는 전체적으로 피인용 수의 영향을 주로 받는 지표(피인용수, h-index, g-index)와 유사한 상관관계를 보였으나, 산점도에서 Quality Factor가 타 지표에 비하여 분산된 분포를 나타내면서 개별식별성이 높은 것으로 드러났으며 군집 분할 분석에서도 타 지표들과 상이한 상관관계를 보여주었다. This paper introduces a new bibliometric measure called Quality Factor, which assesses multiple facets of faculty research performance. The computation of Quality factor is based on a combination of publication count, citation count, h-index, and Impact Factor. In order to analyze the relationship between Quality Factor and other bibliometric measures (publication count, citation count, h-index, g-index, Impact Factor), the study collected publication data of 189 Korean Library and Information Science professors from 2001 to 2014 to produce the rankings of the faculty by each bibliometric measure and computed Spearman's rank correlations between the rankings. The overall results showed Quality Factor to be correlated to citation-driven measures (citation count, h-index, g-index), but the scatterplot as well as rank-interval analysis showed Quality Factor to be distinctive and more discriminating than other measures.

Knowledge about career patterns of women In any profession and about factors which influence these career patterns becomes increasingly necessary because of the influx of ever-increasing numbers of women into the labor force, and the need for the development and utilization of the creative productivity of women. This study alms to investigate Korean female librarians' overall career patterns and verify relevant factors which might affect to their career patterns. As an instrument, self-reported questionnaires were sent to 1,251 full-time Korean female librarians throughout the country with regular librarian's certificate, currently engaging in public, college or university, and special libraries. Based on the data gathered, the interrelationship between their career pattern inclination and its influential factors were examined through hypothesis testing. Major findings of the survey are outlined in the following: 1). Female librarians' career patterns were classified into five categories with the group represented as Categories-2 (single; wishes to continue working after marriage; places an emphasis on the sense of occupational accomplishment and social prestige) accounted for the highest proportion$(33.4\%)$. 2). The result of the hypothesis testing revealed that there is no significant relationship statistically between social factors(parents' socio-economic status, etc.) and female librarians' career patterns. So the hypothesis concerning social factors were rejected. 3). In psychological factors(job satisfaction ; self-concept sex role attitude ; role conflict ; and achievement motivation), all except for self-concept were shown to be relevant with female librarians' stable career pattern. So the hypotheses concerning psychological factors were supported. 4). According to the result of multiple discriminant analysis conducted between the above four statistically significant psychological factors and career patterns, the most influential factor for female librarians' career patterns was job satisfaction and sex role. In conclusion, the following recommendations were made: For overall enhancement of Korean female librarianship, earlier career guidance and concrete sex role education for young women is urgent which enable them to establish correct viewpoint for their occupational career female librarians themselves' constant endeavor In maintaining positive attitude toward their job is required.

지방수령의 지역에서의 교유와 문자 수수 : 19세기 상주목사 홍한주의 사례를 중심으로

Toward the late Joseon Dynasty, the center-local separation becomes clear in many aspects. As Seoul gradually grows into the political and economic center and urbanized extensively, localities couldn`t help becoming relatively weaker. In the literature as well, this phenomenon clearly stood out. Especially as the Southerners in the Yeung-Nam region had their return routes have been blocked, they stick to the tradition of the Confucian Classics as a means to enhance cohesion, based on this focusing on studying the Confucian Classics, and this tendency to put the literature to the bottom. In contrast, in Seoul, literature starts specializing, being separated from the Confucian Classics and the innovative trends like Wihang literature spreaded and a variety of changes become evident. There were the classes that led and accelerated these changes at the time, and they were so-called Kyungwhasejok. This study focused on the fact primarily that, Hong Han Ju (1798-1868), the person from Kyunwhasejok who fully experienced various changes and developments of Seoul in 19th century and obtained most updated knowledge information without distinction were appointed as the governor in the Yeung-Nam region dominated by the conservative and closed Southerners. And by catching this fact, it attempted to investigate how he formed and established the literary relationships as the governor from different region and what the reality of literary collegial relationships. The relationships that he had as the appointed governor of Sangju showed the tendency that the political and the literary relationship were approximately differentiated. Furthermore, Sangju functioned as the basis for Southerners of Yeung-Nam with Toegae School forming the mainstream, but also the academies like Heungahm Seowon and the Seosan Seowon who continued to work after the Westerner Noron-faction people coexisted in it, and showed exchangeability and openness compared with other regions. As a result, Hong Han Ju accepted flexibly the circumstances of the region as well as the political and social situation at the time, properly differentiating and demonstrating his own background, political aspiration, and the literary taste, and built the relationships. What was more notable was the aspect of his literary relationships. Especially, Hong Han Ju who was proud of literary artistic governor was not bothered by factions and classes, and expanded the relationships that sought after solely the literary arts with certain writers and Wihang people who made literary achievements. Although it did not reverberate much, it has a significance in that the Wihang people and men of letters with this literary competence existed even in Yeung-Nam that had particularly strong conservatism in the region in those days in the days of change. This can place certain significance from the viewpoint of the trend of country community literature at the end of Joseon that was blocked from the central literary circle and the micro approach about change. 조선 후기 京·鄕의 분리 현상이 제 방면에서 매우 뚜렷해지고 있었음은 주지의 사실이다. 이러한 분리 현상은 학술 문단의 동향에서도 점차 두드러 지고 있었는데, 그 원인은 서울은 외국 서적의 빠른 유입으로 이미 다양한 지식 정보가 유통되어 그 습득이 매우 용이했던 대신 지방은 외부의 자극에 노출되지 못해 변화 발전의 계기와 발판을 전혀 구축하지 못하고 있었기 때문이다. 문학에 있어서도 마찬가지였다. 특히 영남 남인들은 환로가 차단되면서 결속력 강화 수단으로 講學의 전통을 고수하게 되는데, 이에 기반하여 경학 탐구에 치중하며 문학은 말단으로 치부하는 경향이 더욱 팽배해지게 된다. 이에 반해 서울에서는 이미 문학이 경학으로부터 분리되어 전문화되기 시작하고, 위항문학의 등장과 같은 혁신적 경향이 확산되어 다양한 변화가 두드러지고 있었다. 당시 이러한 변화를 주도하고 또 가속시켰던 부류들이 있었는데, 바로 경화세족들이었다. 본고는 이러한 시각에서, 19세기 서울의 다양한 변화 발전을 온몸으로 체험하고 더불어 최신 지식정보를 가리지 않고 습득했던 경화세족 출신의 洪翰周(1798~1868)라는 인물이 당시 보수적 폐쇄적인 남인 중심의 영남 지역에 수령으로 부임해 구축했던 교유관계와 문자수수의 양상을 밝힌 것이다. 살펴 본 결과, 홍한주는 당대 정치·사회 정세와 지역의 사정을 탄력적으로 수용하면서 자신의 출신과 정치적 지향 그리고 문학적 취향을 적절히 구분 발휘하며 교유관계를 구축하였다. 문학적 교유의 측면에 있어서는, 문예지사로 자부했던 홍한주가 당파 및 신분계층에 구애 받지 않고 문예적 성취가 있는 지역의 일부 문인 및 위항인들과 오로지 문예만을 추구하는 교유를 펼쳤음을 볼 수 있었다. 그 파장이 크지는 못했지만 변화의 시대에 당시 지역에도 특히 보수성이 강했던 영남에도 이러한 문학 역량을 갖춘 위항인과 문인들이 존재했다는 점을 보여준다는 점에서 시사하는 바가 크다고 하겠다. 이는 중앙문단에 가려진 조선 말기 향촌 사회 문학의 동향과 변화에 대한 미시적 접근의 차원에서도 일정한 의미를 부여할 수 있었다.
