To diagnose acute myocardial infarction(MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hema-tologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and bioche-mical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery(LMDA) of the left coronary artery was ligated during the progression(day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group(n=24, thoracotomy without LMDA ligation) and the experimental(MI) group(n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell(RBCs), hemoglobin and hematocrit(HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, choles-terol, total creatine kinase(CK) and isoenzyme MB, and lactate dehydrogenase(LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.

국어과 ‘그려쓰기’ 교수·학습 방법 연구

민현미 한국초등국어교육학회 2006 한국초등국어교육 Vol.32 No.-

본 연구의 목적은 후기문자시대의 변모된 쓰기 문화 양식에 터하여 지금-여기-우리 아이들의 쓰기 문화를 적극적으로 수용함으로써, 당대의 문화적 맥락을 쓰기 수업에 구체적으로 연계시키는 활동을 제안함에 있다. 전자언어시대에는 글과 그림이 의사소통의 대표적 표현 수단이 되며, 이들은 따로 떨어져 존재하지 않는다. 또한 어린이들은 그들의 표현 활동에서 그리는 것과 쓰는 기능을 같은 표현기능으로 인식하고 있다. 이에 연구자는 그림과 시각기호들을 쓰기의 범주 안에 적극적으로 들여와 활용하는 글쓰기 방법의 하나로 ‘그려쓰기’라는 새로운 쓰기 교수‧학습 방법을 제시하였다. 그리고 현행 교과서의 학습 과제들을 세심히 살펴본 결과를 토대로 교과서에서 어린이들에게 제공되고 있는 매체의 종류를 그림, 사진, 몸짓, 만화, 글그림(이모티콘), 광고로 나누고 각각의 그려쓰기 유형을 제시하여 실제 교실에 적용해 보았다. 본고에서의 ‘그려쓰기’는 좁은 의미와 넓은 의미로 나뉜다. 먼저 좁은 의미의 ‘그려쓰기’는 시각적 매체를 활용하여 글을 쓰는 것을 의미한다. 다음으로 넓은 의미의 ‘그려쓰기’는 ‘전자 문화’라 일컬어지는 ‘후기문자시대’에 표출된 징후, 가령 문자와 이미지가 서로를 향해 열려 있는 다양한 도상기호, 이모티콘, 아바타, 블로그 등을 활용한 글쓰기라 정의하였다. 연구에서는 위의 두 개념을 아우르는 개념으로 사용하였으며, 글과 그림의 얽매임에서 벗어나 각각의 장르가 해체되어 서로를 향해 열려있는 오늘날의 ‘장르 가로지르기’ 현상을 반영한 글쓰기라 할 수 있다. This study set out to suggest an activity of associating that kind of cultural context with writing class by aggressively accepting the writing culture of today's children accustomed to the altered writing culture in the post-literal age. In the age of electronic language, writing and drawing are the major means of communication being in need for each other. Thus the investigator devised ‘Geuryeo-sseugi’ for bringing pictures and visual signs into the range of writing and making active use of them. The study placed a focus on the new teaching and learning method for writing. ‘Geuryeo-sseugi’ as in a narrow context means writing using a visual medium. ‘Geuryeo-sseugi’ in a broad context is defined as writing using diverse icons, emoticons, avatars, and blogs where the letters and images are open to each other, which could be major signs of ‘post-literal age’ or ‘electronic culture’. Adopting the concept from both the contexts, the study broke away from the old dualistic thinking and association and pursued writing that would reflect the phenomenon of ‘cross genre’ in which many different genres were disassembled and open to one another.

간접부착술식시 치면과 레진 베이스의 간격 및 접착제에 따른 결합강도

서미영,황현식 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.4

본 연구는 브라켓 간접부착술식시 치면과 레진 베이스의 간격 및 접착제에 따른 전단결합강도를 비교함으로써 브라켓 간접부착의 접착제로서 호제(paste)형 레진 병용의 타당성 여부를 평가해보고자 시행되었다. 소의 하악 중절치 120개를 실험재료로 하여 대조군의 경우 접착제로 실런트만을 사용하는 반면 실험군의 경우 실런트와 호제형 레진을 병용하여, 치면과 레진 베이스 간의 간격이 0.0, 0.2, 또는 0.4 mm가 되도록 접착한 다음 만능물성 시험기를 이용하여 각 시편의 전단결합강도를 측정하고 비교하여 다음의 결과를 얻었다. 1.치면과 레진 베이스 간의 간격이 멀어질수록 두 군 모두에서 전단결합강도가 감소하는 것으로 나타났다. 2.치면과 레진 베이스 간의 간격이 0.0 mm인 경우 양 군 간의 전단결합강도의 차이는 나타나지 않았다. 3.치면과 레진 베이스 간의 간격이 0.2, 0.4 mm인 경우 실런트와 함께 호제형 레진을 병용한 경우의 전단결합강도가 실런트만 사용한 경우에 비하여 통계적으로 유의하게 높게 나타났다. 이상의 연구결과는 브라켓 간접부착술식시 치면과 레진 베이스 간의 간격이 의심될 경우 브라켓 간접부착의 접착제로서 실런트만 단독 사용하는 것보다 호제형 레진을 병용하는 것이 유리함을 시사하였다. (주요 단어 : 간접부착술식, 전단결합강도, 레진베이스, 접착제) The purpose of this study was to evaluate the feasibility of the combined use of paste resin with sealant as an adhesive of the indirect bonding. The resin bases made of light-cured resin were bonded to the bovine incisors at a distance of 0.0, 0.2 or 0.4 mm using the sealant only or the mixture of sealant and paste resin. Bond strength of each group was measured using universal testing machine. The results were as follows : 1.The bond strength was reduced in both groups as the distance between enamel surface and resin base increased. 2.The bond strength showed no statistical difference between two groups in case the distance between enamel surface and resin base was 0.0 mm. 3.In case the distance between enamel surface and resin base was 0.2 or 0.4 mm, the sealant with paste resin group showed significantly higher bond strength than the sealant only group. The results of the present study indicate that the use of paste resin with sealant may be desirable as an adhesive in indirect bonding, particularly in case a gap is suspected between enamel surface and resin base. ※Key words : Indirect bonding, Bond strength, Adhesive, Resin base

방미애,조영자,김현아 한국식생활문화학회 2002 韓國食生活文化學會誌 Vol.17 No.4

The purpose of this study was to investigate the effects of dietary Indongcho(L. japonica Thunb) powder on blood glucose, serum lipid levels and antioxidative anzymes in normal and streptozotocin(STZ)-induced diabetic rats. Four groups of rats(2-week-old inbred Sprague-Dawley male rats) were normal rats fed control diet(NC), diabetic rats fed control diet(DC), normal rats fed Indongcho powder diet(NI), and diabetic rats fed Indongcho powder diet(DI). Diabetes was induced by single injection of streptozotocin(60mg/kg BOW., i.p.). The animals were fed ad libium each of the experimental diet for 5 weeks. Food and water intakes were determined everyday. Blood glucose and serum total cholesterol levels were determined every week. After 5 weeks the animals were sacrificed and activities of antioxidant enzymes and lipid peroxidation products were determined in their liver and kidney homogenates. We also determined serum concentrations of total lipid(TL), total cholesterol(TC), triglycerides(TG) and HDL-cholesterol(HEL-C).Blood sugar and water intake were higher in decreased by dietary Indongcho intake, Body weight gain and FER(feed efficiency ration) were reduced by STZ treatment. But, Final body weight was recovered by Indongcho-contained diet. LHR(LDL-cholesterol/HDL-cholesterol) of the DI group was significantly lower than the other experimental groups(NC, NI and DE groups). The hepatic glucose 6-phosphatase(G6Pase) activity of the groups fed Indongcho diet(NI and DI group) was lower than the groups fed control diet(NC and DC group) and the G6Pase activity of NI group was recovered to the normal levels(p<0.05). However, The glutathione peroxidase(GPx) and glutathione reductase(GR) activities in liver and G6Pase activity in kidney were not statistically different between the control and diabetic control groups. Renal GST activity of the DI group was recovered by Indongcho intake. In conclusion, these results confirm oxidative stress in the liver and kidney of rats with STZ diabetes and antioxidative effect of Indongcho.

매체언어 교육의 관점에서 본 초등학교 어린이들의 애니메이션 서사 수용에 관한 연구

남유미,정현선 이화여자대학교 교과교육연구소 2007 교과교육학연구 Vol.11 No.1

본 논문에서는 영상매체와 인터넷의 발달 등으로 대표되는 변화된 매체 환경이 학생들의 서사경험에 미치는 영향을 고려하여, 초등학교 어린이들의 텔레비전 애니메이션 수용 양상과 그 국어교육적 함의를 살펴보고자 하였다. 오늘날 서사에 대한 경험은 기존의 국어교육이 중시해 왔던 책과 같은 인쇄매체를 통해서 뿐 아니라 영상 매체나 인터넷 매체 등을 통해서도 이루어지고 있다. 특히 초등학교 어린이들에게 있어 텔레비전 애니메이션은 어린이들이 쉽고 재미있게 서사를 경험할 수 있는 매체 텍스트이며, 보다 의미 있는 서사 경험을 위해 교육적 안목과 계획이 필요로 되는 텍스트이다. 본 연구에서는 어린이들이 선호하는 애니메이션 중 <검정고무신>과 <아따맘마>를 선정하여 어린이들의 서사 수용 양상을 살펴보고 국어교육적 함의를 이끌어내고자 하였다. 연구 결과, 어린이들은 이미 대중적인 미디어 텍스트에 익숙해져 있음에도 불구하고, 인물의 시각적 형상화 방식이나 서사의 흐름을 비롯한 영상 언어의 표현 방식에 대해서는 잘 이해하지 못하고 있었으며, 따라서 보다 정확하고 심층적인 이해를 위해서는 교사의 의도적이고 계획적인 영상서사 이해교육이 필요함을 알 수 있었다. 한편 같은 대중매체 텍스트라 하더라도 어린이들의 발달 단계에 따라 인물에 대한 선호나 이해도에 차이가 있었고, 텍스트의 의미에 대한 이해나 주제에 대한 소화력에도 차이가 있음을 알 수 있었다. 따라서 어린이들에게 애니메이션을 통한 서사 교육을 실시하고자 할 때에는 어린이들의 인지적, 정서적 발달 단계 등을 고려하는 교육적 안목이 필요함을 알 수 있었다. This article explores the ways in which primary school children might understand the narratives of popular television animation programs. Television animations are media texts which are regarded as important resources for Korean language education particularly in the recently revised national curriculum for Korean. Children can learn about the aspects of multimodality and narratives of the moving images by watching television animations. Drawing on the children's responses after watching popular television animations, <Black Rubber Shoes> and <Atashinchi>, this article finds out that children need to learn more systematically about the ways in which moving images construct narratives. This article also argues that children's abilities to understand the narrratives of animations are dependent on their mental, emotional and social development which needs to be considered in terms of selecting animation texts for their learning.

민족적 전통과 동양적 전통 : 1930년대 후반 경성과 동경에서의 <춘향전> 공연을 중심으로 Focusing on <Chunhyangjeon> Performed in Korea and Japan During the Late 1930's

백현미 현대문학이론학회 2004 現代文學理論硏究 Vol.0 No.23

The play <Chunhyangjeon(춘향전)> was based on the Korean classic novel with Chosun(조선) dynasty setting. Singers who were disciplined in Korean traditional music usually had practiced <Chunhyangjeon> for a long time. During the late 1930's, there were new phenomena that <Chunhyangjeon> were performed in Korean modern troupes and Japanese modern troupe. This study is to show how the phenomena were going on and why those appeared, focusing on the relationship between nationalism and 'theory of orient'. The Korean modern troupe 'Drama Academy(극예술연구회)' performed <Chunhyangjeon> written and directed by Yoo Chijin(유치진) at Kyrmgsung in Korea in 1936. Yoo Chijin tried to take in Korean traditional performance called 'Pansori(판소리)' through the play, like Japanese modern troupes succeeding in Japanese tradition performance called 'Kabuki'. Even though he was interested in Korean tradition in respect of nationalism, his play was also connected with 'theory of orient' proposed by Japanese. 'Tokyo Student Art Group(동경학교예술좌)' was organized by Korean students studying in Tokyo in 1934. The group played <Chunhyangjeon>(playwrighter Yoo Chijin, directer Joo Youngseb; 주영섭) in Tokyo in 1937, using western style music and Japanese Kabuki style action. The Japanese modern troupe 'Sinhyup(新協)' played <Chunhyangjeon> in Tokyo in early 1938, and played also at several places in Korea in the late 1938. A Korean Jang Hyukju(장혁주) who had written novels with the Japanese language wrote the play in Japanese. The director Murayanra Tomoyosi(村山知義) cast a woman for hero role, and made actors and actresses practice Kabuki. He announced <Chunhyangjeon> as 'oriental classic work'. Actors and actresses of the play were all Japaneses. The <Chunhyangjeon> performed by the company 'Sinhyup' was the case substituting Japanese style play for Korean performance. In the last period of Japanese imperialism, Japan educated Naesonilchae(內鮮一體) to Choson's people in order to dominate its colony exploitation. It was related to Daedonga-Gongyeongnon(大東亞共榮論) and 'theory of orient(동양주의)'. The theory of orient was based on the criticism on the Western modernity, the presentation of Japan as a center of East and the unification of the Korean people into Japanese. <Chunhyangjeon> plays performed in Korea and Japan in the last period of Japanese imperialism reflected 'theory of orient' consciously and unconsciously.
