서혜영,김규한 이화여자대학교 환경문제연구소 1997 이화환경연구 Vol.1 No.-

한강 수계 분지 내의 하천수 (지표수)와 서울 지역 지핫의 화학적 특성 규명과 용존 이온종의 기원을 연구하기 위해 1996년 3월-4월 동안 하천수 시료 60개에 대하여, pH, TDS 등과 용존이온의 화학분석을 실시하였다. 남한강과 북한강 하천수의 화학성분은 주로 수계분지 지역에 분포하는 암석에 의해 영향을 받고 있으며, 한강본류의 하천수는 인위적인 오염에 의한 영향이 크게 나타나고 있다. 즉, 남한강은 상류지역에 분포하는 탄산염암, 탄광 및 금속광산 폐수등에서 용출된 Ca(), Mg(), HCO(), SO() 등이 현저하며 북한강은 화강암질암의 풍화 산물인 K(), Na(), Ca()등의 이온종이 특징적이다. 한편 양수리에서 상기 2개 하천이 합류하여 서울 도심을 지나는 한강 본류는 SO(), NO(), PO(), Cl()등 생활하수 오염의 영향이 현저하게 나타나고 있다. 한강 본류로 유입되는 서울 지역의 왕숙천, 탄천, 중랑천, 안양천의 4개의 지천은 NO(), Cl(), PO(), SO(), Mn등 인위적인 오염현상이 크게 나타나고 있다. 한강 하천수의 화학 성분의 군집, 요인 및 회귀 분석 결과, 전체 자료 분산은 오염 인자에 의한 분산이 약 79%, 지질과의 물-암석 반응에 의한 분산이 약 7%이다. 남한강과 북한강의 합류 지점에서의 Cl에 대한 혼합 비율은 약 60:40이다. 1981년 분석 자료와 1996년 자료의 비교에서 암석 풍화에 의한 1차적 용존 성분인 Ca(), Mg(), HCO()등은 변화가 적으나 Na(), NO(), PO(), SO()등 인위적 오염원의 성분은 크게 증가하는 경향이 있다. To investigate geochemical characteristics and the sources of the dissolved ion species in the river water in the Han river drainage basin, samples were collected at 60 sites from the Han river drainage basin. The data for pH, conductivity, TDS(total dissolved solid), temperature, and concentrations of dissolved ions were obtained as follows:(1) The geochemical characteristics of the surface water in the South and North Han river drainage basins are mainly controlled by bed rock geology in the drainager basin and in the main stream of the Han river considerably affected by anthropogenic pollution. The South Han river water samples have high concentration of Ca() (ave. 15.42ppm), Mg()(ave. 2.74 ppm), HCO()(ave 51.9ppm), which evidently indicates that the bed rock geology in a limestone area mainly controls the surface water chemistry. The concentration of SO() is remarkably high(SHr10-2:129.9ppm) because of acid mine drainage from the metal and coal mines in the upper reaches of the South Han river. (2)The South Han river and the North Han river join the Han river in the Yangsuri, Kyounggido and flow through Seoul metropolitan city. The mixing ratio is about 60:40 at the meeting point(sample number HR10). (3)The result of factor analysis suggests that the pollution factor accounts for about 79% and the bed rock type factor accounts for about 7% of the data variation. This means that the geochemical characteristics of the Han river water mainly controlled by anthropogenic pollution in the South Han river and main stream of the Han river drainage basin. (4)The chmical data for four tributaries such as the Wangsukcheon, the Tancheon, the Zungrangcheon, and the Anyangcheon show that the concentration of pollution elements such as NO(), Cl(), PO(), SO() and Mn are high due to municipal waste disposal.

애니메이션 얼굴 이미지의 선호 피부색

한혜진(Hye Jin Han) 한국애니메이션학회 2015 애니메이션연구 Vol.11 No.1

선호 피부색은 색 재현 분야에서 중요한 주제로 긴 역사를 바탕으로 방대한 연구가 축적되어 있다. 그러나 애니메이션에서의 선호 피부색은 연구된 사례가 별로 없다. 최근 제안되었던 캐릭터의 피부색을 중심으로한 애니메이션 색채 설계(한혜진·이성은, 2014)를 발전시키기 위해, 실제 피부색과는 다른 경향을 가진 애니메이션에서 선호 피부색을 새로운 연구 대상으로 주목할 필요가 있다. 따라서 이 연구에서는 애니메이션 얼굴 이미지의 선호되는 피부색을 알아보고자 했다. 첫째, 실제 일본의 스튜디오 지브리에서 제작된 애니메이션에 쓰이고 있는 피부색의 범위를 조사했다. 조사방법으로 고정된 모니터에 애니메이션 화면을 띄우고 휘도계로 측색을 실시했다. 측색 결과, 실제 피부색의 측색치보다 범위가 넓어져 있어 피부색에 대한 강한 기억색의 영향을 확인했다. 둘째, 애니메이션 얼굴 이미지의 선호 피부색을 순위상관법을 이용하여 조사했다. 실험 방법으로 피험자에게 동일한 조건에서 애니메이션의 얼굴 이미지와 사각형의 색표를 이용하여 선호하는 피부색의 순위를 매기게 했다. 각각의 매겨진 순위를 이용하여 스페어만순위상관계수(Spearman’s Rank Correlation Coefficient)를 계산했다. 자극에 따른 순위상관계수를 비교한 결과, 애니메이션 얼굴 이미지와 사각형 색표에서 선호 피부색이 다른 경향을 띤다는 것이 나타났다. 애니메이션 얼굴 이미지에서도 선호 피부색이 존재한다는 것이 심리물리학적인 실험을 통하여 확인되었다. 더불어 애니메이션 제작을 위한 색 재현 데이터베이스화의 가능성을 확인했다. The study of preferred skin color has been accumulated based on long history, because of important theme in color reproduction. However, preferred skin color in animation has been hardly researched. For developing a proposal of color planning for film image based on character’s skin color(Han&Lee, 2014), the study of preferred skin color in animation, which has unique trends differed from real skin color’s one, is needed to pay attention as a new theme. In this study, preferred skin color in animation will be clarified. Firstly, skin colors in Japanese studio ghibli’s animation were investigated for making sure of the range of skin color in real animation fields. Showing still images of animations on a monitor, skin colors of the images were measured by a luminance meter. Because skin colors’ in the animations were wider than real skin colors’ one, strong effects of memory color could be considered. Secondly, preferred skin color of animation facial images was researched by rank order method. In the same experiment’s condition, subjects determined the raking of preferred skin color using facial images and rectangle color chips. The ranked orders of preferred skin color were calculated as Spearman"s rank correlation coefficient. The differences between facial images and rectangle color chips were identified, comparing the rank correlation coefficients. Through the psychological physical experiment, existences of preferred skin color in animation were ensured. Moreover, possibilities to database for color reproduction of animations were identified.

Purpose: The purpose of this study was to test the effect of Reciprocal Peer Questioning (RPQ) on nursing students’ metacognition. Methods: The study design was an one group pretest-posttest design. Participants were 47 second-year nursing students. They underwent the course of 'Health assessment' by the lecture and RPQ. Data was collected through self-report questionnaire. SPSS 18.0 program was used for data analysis. Results: The mean score for metacognition was 104.81±12.01 (range 30~150). The score of metacognition (metacognitive knowledge and metacognitive regulation) was significantly improved after RPQ. Academic achievement wasn’t significantly correlated with metacognition. Conclusion: As revealed by the results, RPQ helps students improve their metacognition. RPQ can be applied alone or in combination with the other teaching and learning strategies to improve metacognition.

게임의 서사와 상호작용성

This study is aimed at examining the feature of interactivity in narrative of game. The former study of game was limited only to the narratologist's result that interactivity would destroy traditional narrative. But in computer environment, a lack of linearity does not simply destroy narrative. Interactivity is not in the former linear literature like novel or film which is ruled by Aristotelian dramatic experience. So it allows us to play stories that we couldn't tell before, Interactivity is the most distinctive resource of new narrative. For example in game, player must get an experience of agency witch include immersion and transformation because high interactivity and strong story are combines each other. It makes the narrative multi-sensory, procedual, spacial, participatory and encyclopedic as Janet Murray suggested. But the concept of interactivity in game is not simple as the former narratologist like Janet Murray suggested. The purpose of my study is to distinguish four strategic forms of interactivity(internal/external and interpretive/creative) to show how different types of interactivity create different type of narrative. Linear narrative and interactive game are totally different. We have to define exactly what the interactivity in game is so that we can find a way to understand the narrative of game which is the total interactive experience consisted of both first person engagement third person reflection.

Quentin Compson의 이야기 : Absalom,Absalom!의 구조

韓惠卿 同德女子大學校 1992 同大論叢 Vol.22 No.1

On one side William Faulkner's Absalom, Absalom.! is the story of Thomas Sutpen's grand design. He attempts to build a mansion and found a respectable white dynasty. On the other side it is the story of the storytellers' effort to tell the Sutpen's story. They attempt to construct a narrative instead of a mansion. It is because of the novel's double focus that most of its actions takes place in Yoknapatawpha, Mississippi, in the nineteenth century while most of its telling takes place In Cambridge, Massachusetts, in the twentieth century. Of four storytellers, Quentin, with the aid of his roommate, Shrove, pieces together all the facts and conjectures about the Sutpens and recreates them. It is most important that he cares most about what Sutpen signifies. He belives that the life of Sutpen represents not only the essence of the history of the South but a part of the mythos in which he himself still lives. After all, the story of Sutpen is nothing but the part of the Southern past which Quentin mustunderstand if he is to understand himself. True understanding of the Sutpen's tragedy can only come through Quentin, who suffers an emotional identification with the . Sutpen phantom-shapes of his own Southern past. Absalom, Absalom! is Quentin's story rather than the story of Sutpen who dies without understanding the meaning of life. Quentin, in the sense of traditional concept of tragedy, cannot be a tragic hero. He neither initiates nor is involved in an action of magnitude, He can do nothing about his tragic perceptions except tell about them. And yet his telling itself must be tragic. It is through Quentin's telling of tragic perceptions that the Sutpen tragedy has any meaning. In this sense, the text of Absalom, Absalom! ends with Quentin's recognition of his hopeless impasse.

The chemical components of radish buds were investigated during the growth stage. The vitamin C and total phenol contents were lowered after 4 days of early sprout growth, and were 22.19 and 4.99 mg%, respectively.These increased according to the growth time, showing the highest value on day 8, 25.85 and 17.87 mg%, respectively. However, these values decreased around day 12, which seemed to be the bud end point. The major free sugar component of the radish buds was glucose, showinged the highest content on day 8. The total organic acid content gradually increased as the growth proceeded. The detected oxalic acid content was only small on day 8. During the early growth stage, the total and essential amino acids contents were 3,020~3,575 and 1,206~1,499 mg, respectively. These contents tended to decrease with growth time. Glutamic acid, aspartic acid and alanine were the major amino acid components (39%).

토양 미생물인 Streptomyces tubercidicus에서 분리한 GTPcyclohydrolase Ⅰ 저해제

한지만,김시욱,이인화,박열,정혜광,윤성명,유진철 조선대학교 약학연구소 1998 藥學硏究誌 Vol.19 No.1

GTP cyclohydrolase I (EC 3.5.4.16) catalyzes the conversion of GTP to D-erythro-7,8-dihydroneopterin triphosphates and formic acid. and thus performs the first committing step in the biosynthesis of the pteridine moiety of folk acid in microorganisms and of tetrahydrobiopterin in higher animals. GTP cyclohydrolase I isolated from Streptomyces tubercidicus was inhibited by DL-6-methyl-5,6,7,8-tetrahydropterin and xanthopterin, and was not inhibited by tetrahydrofolic acid, pterin, pterin-6-carboxylic acid, biopterin, neopterin, ribofravin. These results suggest that bacterial GTP cyclohydrolase I may be regulated by its metaboilic end product.

Purpose: The purpose of this study was to determine what qualities students rate in their peer evaluations and to analyze factors affecting performance. Methods: The data were collected from 60 second-year nursing students who took the course 'Pathology'. Each team was composed of 5~6 students, each of whom evaluated other members by using peer evaluation instrument. Data were analyzed using SPSS WIN 18.0 program. Results: Students in the highest IRAT tertile showed a significantly higher score in peer evaluation than other tertiles. Students' reason for giving the highest and lowest score were both the quality of contributions during team discussion. The most affecting factor of the course grade was peer evaluation score(=.52, p〈.001). Conclusion: Peer evaluation could be considered as a complement for a comprehensive evaluation strategy. This results may be useful for educators to determine a percentage-multiplier in calculating the course grade.
