This study was conducted in order to investigate the effects of the whitening and antioxidant activities of Inulae flos with water using microwave assisted extraction (MAE) and pressure heating extraction (PWE). The total polyphenol and flavonoid compound contents from extracts obtained by MAE 67.75 mg/g and 26.28 mg/g, respectively were higher than in those obtained by PWE. Contents derived from PWE, however, showed the highest levels of electron donating ability activity 90.98% at a concentration of 1.0 mg/mL. As for superoxide dismutase-like activity, PWE showed the highest value 69.86% at a conditon of 1.0 mg/mL, while the activity from MAE was 27.32%. The nitrate scavenging ability of contents derived from PWE revealed their highest effects at the pH 1.2 (86.88%) and pH 3.0 (75.26%) at a concentration of 1.0 mg/mL. The tyrosinase and elastase inhibiton rates were greater in contents derived from MAE 14.81% and 15.71%, respectively. Measurements of the collagenase inhibiton rate revealed 24.09% and 24.62% in extracts obtained by MAE and PWE, respectively. These results suggested that the water soluble extract of inulae flos could be used as an antiwrinkling agent, as well as an antioxidant resource for functional foodstuff, cosmetics, and beauty industry materials.

‘타자’들의 잔혹사 : 연상호 애니메이션

서수정(Seo, Soo-Jung) 한국만화애니메이션학회 2014 만화애니메이션연구 Vol.- No.37

인간의 자유로운 상상력보다 있는 그대로의 비루한 현실을 재현하는 연상호 애니메이션은 사회성 짙은 리얼리즘 계열의 작품으로 한국애니메이션에서 독특한 지점에 위치한다. ‘현실보다 더 현실 같은 이야기’로 평가받는 연상호 애니메이션이 일관되게 재현해온 이야기는 우리 사회 중심부의 이면에 거주하는 사람들의 세계 즉 ‘타자’의 이야기이다. 연상호 애니메이션은 주류 공간의 뒷골목에서 사회적 타자로 살아가는 그들의 잔혹한 현실을 직설적 화법으로 재현한다. 또한 판타지가 거세된 차가운 현실풍경 뿐만 아니라 인물들의 욕망과 감정을 생생하게 중계하면서 후기자본주의 시대를 살고 있는 우리들의 모습을 현미경처럼 담아내고 있다. 그러므로 본 논문은 연상호 애니메이션을 한마디로 ‘타자들의 잔혹사’로 규정하고 그의 애니메이션이 형상화하고 있는 현실풍경과 인물들의 욕망과 감정을 구체적으로 탐색하였다. 우선 연상호 애니메이션이 재현하는 현실은 부조리한 곳으로, 이곳의 부조리는 견고하고 적대적인 사회시스템과 하류계급에 속한 채 트라우마에 시달리는 인물들을 통해 구축된다. 그래서 희생양이나 호모 사케르로 살아가는 연상호의 인물들은 ‘사악한 희생양’ 또는 ‘타락한 괴물’로 구체화되고 그들의 현실풍경은 지옥으로 형상화된다. 후기자본주의 시대가 배태하고 있는 타자의 모습, 레비나스의 용어를 빌리자면 ‘타자의 얼굴’을 통해 우리가 외면하거나 부정해온 우리의 모습을 소환하고 있는 연상호 애니메이션은 우리 사회의 환부를 적나라하게 전시하면서 이 시대의 민낯과 불편한 진실을 들추어내고 있다. 그리고 그를 통해 현실을 고발하고 진실을 탐색하는 재현언어로서의 한국애니메이션의 가능성을 증명하고 있다. Yeon Sang-Ho"s Animation occupies an exceptional place in Korean Animation, being categorized as the kind of realism representing the pitiable actuality rather than the liberal and creative imagination. His animation appreciated as ‘stories much more real than the reality’ mainly depicts the world of ‘the others’ who resides on the periphery of the society in a rough and straightforward way. Yeon Sang-Ho"s Animation represents the emotions and desire of characters as well as the heartless real world refusing the fantasy, through which it reflects the portraits of people living in post-capitalistic era seen from the microscopic view. This article investigates the textual characteristics, defining his animation as the Brutal history of "The Others". Two conditions which constitute the actual world in his works are the absurd social system and the characters who are afflicted with the trauma, belonging to the lower classes. Therefore, the landscape of real life which contains vicious victim, corrupted monster and being as ‘homo sacer’ looks like a painting of hell. Yeon Sang-Ho"s Animation summons the shadow of ourselves which has been negated or neglected through the figure of ‘the others’ produced in post-capitalistic era and exposes our bare face and the uncomfortable truth by displaying the affected area of out society plainly. Furthermore, his works demonstrate the possibility of Korean animation as a representational language of facing the reality and searching for the truth.

한국 독립애니메이션의 미학적 특성과 사회적 소통방식 연구

서수정(Seo, Soo-jung) 한국만화애니메이션학회 2017 만화애니메이션연구 Vol.- No.47

본 논문은 한국 유일의 독립애니메이션 영화제인 ‘인디애니페스트’ 수상작을 대상으로 한국 독립애니메이션 이미지를 탐색하여, 예술성과 사회성이 긴밀하게 조응하는 한국 독립애니메이션의 미학적 특성들을 분석하고 미학적 특성을 통해 구축되는 사회적 소통방식을 구체적으로 탐색하였다. ‘인디애니페스트’ 수상작들을 통해 한국 독립애니메이션이 보여주는 있는 말 걸기 방식은 세 가지다. 첫 째는 느낌과 충동, 욕망을 조형적으로 재현하여 수화나 음향처럼 직접적이고 감각적인 이미지로 말을 거는 방식이고 두 번째는 이미지로 다르게 말하기 방식 즉 일상의 익숙한 이미지를 새로운 방식으로 변주하거나 재배치하여 우리 안의 내밀한 리듬이나 정서, 찰나적 성찰이나 사유를 들려주는 방식이며 세 번째 방식에서는 현실과 비현실이 모호하게 중첩된 새로운 층위의 현실세계를 통해 ‘변방에서 새어나오는 소음으로밖에 지각되지 않았던 목소리’들을 현실의 담론으로 들리게 만든다. 애니메이션은 본원적으로 이미지로 ‘의미를 발화하고 소통하는’ 매체로서, 언어나 서사를 통해 시행되어 왔던 ‘의미를 발화하고 소통하는’ 방식과 다른 차원 즉 기존의 사회적 목소리와 다른 새로운 방식의 말 걸기 양식을 실행하고 구축해 왔다. 하지만 그럼에도 독립애니메이션을 비롯해서 ‘애니메이션을 이미지를 통한 사회적, 정치적 말하기라는 관점에서 접근한 연구’는 국내는 물론 국외에서도 쉽게 찾아보기 어렵다. 따라서 애니메이션을 인류 최초의 사유방식이자 재현화법으로서의 성격을 계승하고 있는 매체로 접근하여 이미지를, 이야기를 생산하고 의미를 발화시키는 주체 즉 일종의 소통 언어로 탐색하고자 하는 본 논문은 애니메이션학의 균형 있는 발전을 위해 필요한 연구이다. 또한 본 연구는 한국 독립애니메이션을 학문적 관점에서 재조명하고 보다 폭넓은 시각에서 정당한 가치를 발굴하고 평가받도록 하는 데에도 기여할 수 있을 것이라 생각된다. This paper analyzes Korean aesthetic characteristics of Korean independent animation, which is closely related to artistic and social characteristics, by searching Korean independent animation image for the winner of "Indie AniFest", the only independent animation film festival in Korea. And social communication methods. There are three ways in which Korean Independence Animation shows the way of speaking through award-winning works. The first is a method of expressing feelings, impulses, and desires in a formative way, and a direct and sensuous image as in sign language or sound. In the second method of speaking differently with images, in the third method, It makes the voice of the fringe through the real world of the story sound as a story of reality. Animation is a medium that "originalizes and communicates meaning" as an image, and has implemented and constructed a new way of speaking, which is different from existing social voices. Nevertheless, it is not easy to find a research that approaches animation from the viewpoint of social and political speech through images. Therefore, this paper is necessary for the balanced development of animation. In addition, this study can contribute to re - examining Korean independent animation from an academic point of view and to discover and evaluate fair value from a wider perspective.

서수정(Soo Jung Seo),심규봉(Kyu Bong Shim),김남우(Nam Woo Kim) 한국식품영양과학회 2011 한국식품영양과학회지 Vol.40 No.10

남천(Nandina domestica) 열매를 물과 에탄올 추출 후 극성이 상이한 유기용매를 순차적으로 분획하여 각 추출물의 생리활성을 측정하였다. 폴리페놀은 EE(ethyl acetate fraction of ethanol extract)에서 922.22 mg/g이었으며, 플라보노이드는 EB(butanol fraction of ethanol extract)에서 282.49 mg/g을 함유하였다. WA(aqueous of water extract)와 EH(n-hexane fraction of ethanol extract)는 0.1 mg/mL에서 93% 이상의 전자공여활성을 나타내었으며, 분획물의 농도 증가에 따른 전자공여능의 유의적 차이는 없었다. SOD 유사활성은1.0 mg/mL의 EA(aqueous of ethanol extract)에서 56.36%로 가장 우수하였으며, EH와EC(chloroform fraction of ethanol extract)에서도 50% 이상의 활성을 나타내었다. 아질산염 소거는 pH 1.2의 EC에서 82.03%로 가장 높았다. Xanthine oxidase 저해율은 0.5 mg/mL에서 WE를 제외한 모든 분획물에서 90% 이상의 저해율을 나타내었으나, WE는 46.75%로 가장 우수한 tyrosinase 저해효과를 나타내었다. 이상의 결과 남천 열매 분획물은 다량의 폴리페놀과 플라보노이드를 함유하고 생리활성 효과가 우수하여 천연 항산화 제재 및 이를 이용한 의약품 개발 가능성을 지닌 약용 식물자원인 것으로 판단된다. This study was carried out to compare the antioxidative effects of various Nandina domestica fruits extracts. Organic fractions, including n-hexane, chloroform, ethyl acetate, and butanol fractions, were obtained from the water and ethanol extracts of N. domestica fruits. The phenolic compound content of the EE fraction was 922.22 mg/g. The flavonoid compound content was highest in the EB fraction (282.49 mg/g). The electron-donating ability was highest (93%) in the WA and EH fractions at 0.1 mg/mL. The SOD-like activity was showed the highest in the EA fraction (56.36%), and EH and EC both showed higher than 50% activity. The nitrite-scavenging ability of the EC fraction at 1.0 mg/mL under pH 1.2 conditions was 82.03%. The xanthine oxidase inhibitory activities of all the fractions, except WE, were higher than 90% at 0.5 mg/mL. The effect of tyrosinase inhibition was highest in the WE fraction (46.75%). These results show that the N. domestica fruits fractions contained high levels of polyphenol and flavonoid compounds, along with excellent antioxidative effects. This suggests that N. domestica fruits can be used as a functional material.

This study aims to derive a three stage plan to introduce localism within the context of urban regeneration projects. The first step is to establish a local concept based on the definition of local terms with an understanding of the expansion of terms used in various fields. The concept of localism in urban regeneration was derived by examining the local concept in regional studies in the field of sociology. At this time, local-related regional studies confirmed research trends over the past 20 years from the year 2020 to August 2021 by using the search function of the Korean academic journal Index(KCI). The second step examined the conceptual characteristics of localism by examining the terminology found in various fields where the concept of local appeared. BIG KINDS news big data was used to analyze through keywords such social and cultural trends that have changed over the past 30 years. The third step was to find the limitations of localism and introduce measures for urban regeneration projects. After examining the progress of urban regeneration projects, seven previous studies that encompassed empirical methods of surveys, expert opinions, field interviews, and in-depth interviews were reorganized and synthesized, and an alternative to localism in urban regeneration projects was presented.
