현선희 한국초등무용학회 2001 한국초등무용학회지 Vol.6 No.1

The purpose of this study was to identify the participation of the female and the male students and the interaction patterns in the elementary dance classes. For this study I observed the third-grade dance classes at Peacod elementary school in Seoul. The research system was the ethographic study that was based on the qualitative methodology. Data were collected through various methods such as in-depth interviews, video-tapes and document analysis. There were differences in the female and the male students. Four styles of the participation were categorized in boys; 'the leaders', 'the sympathizers', 'the spectators', and 'the desperate dancers'. 'The leaders' in group showed that they were active, creative, and scientific, and that they decided to adopt methods democratically. 'The sympathizers' showed that they were negative in the expressions and that they took in proposals of colleagues and followed them well. 'The spectators' showed that they were indifferent to their tasks, and didn't manage their tasks well. 'The desperate dancers' showed that they intented to their tasks, but couldn't participate in their tasks. Three styles of the participation were categorized in girls; 'the taking care of', 'the interferers', 'the sympathizers'. 'The taking care of' showed that they were positive, highly skilled in their tasks, and took after their colleagues. 'The interferers' showed that they were ardent to do their tasks and contended for victory. Their skills were high or medium. 'The sympathizers' showed that they were negative but participated in their tasks. There were sexual differences in the interactions, too. The interactions were divided into two classes. First class was to do the task participation, the task appreciation, and the environments. Second class was boy to boy, girl to girl, boy to girl. In the task participation, boy to boy showed scolding, forcing, and pacifying; girl to girl showed pacifying, scolding, rebuking, forcing, and satisfying; boy to girl showed disputing, forcing, cooperating, and ignoring, In the task appreciation, the interactions were classified the positive and the negative. The positive interactions were admiration, encouragement, mimicry, control, self-satisfaction and banter; the negative interactions were indifference.

어린이 대상 영상 창작 교육의 국어교육적 함의

정현선 한국초등국어교육학회 2006 한국초등국어교육 Vol.30 No.-

본고는 초등학교 어린이들이 공동으로 창작한 영상물에 대한 소규모의 사례 연구를 시도함으로써, 창작 주체로서 어린이들이 영상 언어를 통해 생산하는 의미를 탐색하고, 이를 바탕으로 영상 창작 교육이 언어교육과 문화교육으로서의 국어교육에 지니는 함의를 도출하고자 하였다. 영상 창작 교육의 과정에 있어 교사는 어린이 작가들에게, 그들이 생성한 아이디어에 대해 질문을 하고 그들의 작품을 함께 해석하고 토론함으로써, 그들의 작품에 반영된 복잡하고 풍부한 생각과 관심들에 대해 대화할 수 있게 된다. 본고는 이러한 과정을 통해 어린이와 교사는 서로가 가진 사회적 담론을 경청하고 공유하게 됨으로써 서로에게서 배울 수 있게 되는 것이 대화적 문화를 만들어가는 영상 창작의 미덕이라 보았다. 어린이 대상 영상 창작 교육은 이처럼 매우 귀중한 대화를 촉발하는 복합 문식성 교육의 의미 있는 계기로서 국어교육에 기여할 수 있다고 보았다. This article discusses the pedagogic implications of children's moving image production within the context of Korean language and cultural education, based on a case study of making an animation text by primary school-aged children. The fact that children can make multimedia texts more freely than in school would not automatically guarantee that they become truly multiliterate, considering that multiliteracies mean a capacity to communicate through the ‘textual multiplicity,’ in terms of the multiplicity of cultural diversity as well as of modes of communication, ultimately in order to 'redesign the social futures'. This article argues that respecting the 'authorship' of children in media production does not necessarily means that the teacher cannot provide different perspectives which children might like to consider. In order to produce multimedia texts, children need to learn appropriate knowledge and skills such as multimodal communication, technical skills of operating the equipment, artistic conventions and social discourses. Children have the right and need to be provided with diverse discursive resources, which would affect the learners' internal dialogues, which would ultimately enrich their media production. In the process of asking questions and interpreting children's works, adults are bound to be engaged in a dialogue with the rich, complex ideas, concerns and voices of the children which are reflected in the media productions. As such, children and adults could learn from each other in the process of listening and sharing, that is reciprocal scaffolding. Children's media production can be a significant instigation for such a precious dialogue.

소아에 있어서 뇌전산화단층 촬영상 결절성 두개강내 병변에 관한 임상적 연구

박현선,최중언 대한신경외과학회 1989 Journal of Korean neurosurgical society Vol.18 No.4

To make guideline to the diagnosis and treatment and or the intracranial nodular lesions, the authors made a clinical analysis on 81 pediatric patients who had showed nodular lesions on brain CT scan at Severance Hospital from Mar. 1979 to Feb. 1989 and the results were summarized as follows. 1) The peak incidence of intracranial nodular lesions were found in the 2nd decade(61.7%). There was no sexual difference. 2) The most common clinical symptom was seizure(92.6%) and the predilection site was parietal area. The nodular enhancing type on brain CT scan showed not only the most common type but also the most favorable clinical course. 3) As the etiology of the intracranial nodular lesions, tuberculosis, paragonimiasis, cysticercosis, tumor(meningioma), and aspergillosis were confirmed or suspected, but tuberculosis was the most common. CSF routine examination, chest PA, PNS X-rays, skin test for paragonimiasis and tuberculosis, CSF ELISA test for cysticercosis and paragonimiasis should be routine as the diagnostic studies. 4) We made treatment principle for intracranial nodular lesions. In cases that initial brain CT can show low density or calcified density without contrast enhancement, we treat those patients with anticonvulsants and steroid with regular check-up. If the lesion increase in size or new enhancement develops on follow up CT scan, medications for the suspected etiology should be added. In cases that initial brain CT scan show enhancing lesions, treatment is started with anticonvulsants and medications for the etiology regular check up. If the lesion increase in size on follow up CT scan or seizure is uncontrolled, surgery should be considered.

이 연구의 목적은 쐐기형 5급 와동과 근관와동을 복합레진으로 수복한 상악 제2소구치에 대한 응력 분포를 3차원 유한요소법으로 분석하여 평가하기 위한 것이다. 발치된 상악 제2소구치를 이용하여 Micro-CT로 스캔한 후 3D-D0C-TOR로 3차원 유한요소 모형을 제작하였다. 제작된 소구치 모형에 근관 와동을 형성하고 쐐기형 5급 와동과 글래스 아이오노머 기저재의 사용 여부를 구분하여 근관 와동을 혼합형 복합레진으로 충전하였다. 협측 교두 또는 설측 교두에 500 N의 하중을 가하고, ANSYS 8.0 프로그램으로 인장 응력의 분포를 분석하여 평가한 결과 베이스 사용유무에 따른 응력 분포의 차이는 없었다. 협측 교두에 하중이 가해질 때, 하중점과 교합면의 중심구, 구개측 백악법랑경계부에 과도한 인장 응력이 집중되었으며, 5급 와동이 없는 경우보다 5급 와동이 있는 경우에 약간 더 높았다. 설측 교두의 협측 경사면에 하중이 가해질 때, 하중점과 교합면의 중심구, 협측 치경부에 과도한 인장 응력이 집중되었으며, 5급 와동이 있는 경우가 5급 와동이 없는 경우보다 약간 더 낮았다. The purpose of this study was to investigate the distribution of tensile stress of canal obturated maxillary second premolar with access cavity and notch-shaped class Ⅴ cavity restored with composite resin using a 3D finite element analysis. The tested groups were classified as 8 situations by only access cavity or access cavity with notch-shaped class Ⅴ cavity (S or N), loading condition (L1 or L2), and with or without glass ionomer cement base (R1 or R2). A static load of 500 N was applied at buccal and palatal cusps. Notch-shaped cavity and access cavity were filled microhybrid composite resin (Z100) with or without GIC base (Fuji Ⅱ LC). The tensile stresses presented in the buccal cervical area, palatal cervical area and occlusal surface were analyzed using ANSYS. Tensile stress distributions were similar regardless of base. When the load was applied on the buccal cusp, excessive high tensile stress was concentrated around the loading point and along the central groove of occlusal surface. The tensile stress values of the tooth with class Ⅴ cavity were slightly higher than that of the tooth without class Ⅴ cavity. When the load was applied the palatal cusp, excessive" high tensile stress was concentrated around the loading point and along the central groove of occlusal surface. The ten-sile stress values of the tooth without class Ⅴ cavity were slightly higher than that of the tooth with class Ⅴ cavity.

성찰적 문화교육으로서의 미디어 리터러시 교육

정현선 국어교육학회 2002 國語敎育學硏究 Vol.14 No.-

본고는 새로운 미디어 환경에 따른 새로운 커뮤니케이션 방식을 국어교육의 장에 어떻게 수용할 것인가의 문제를 고찰하고 있다. 인쇄 매체 중심으로 이루어져 온 국어교육이 전통적인 리터러시 교육을 넘어서, 변화된 시대적 요청에 부응하는 새로운 미디어 미터러시 교육이라는 보다 넒은 커뮤니케이션 교육의 영역 속에서 그 위상과 사회적 역할을 재고해야 한다는 것이 주요 논지이다. 필자는 이를 능동적이고 성찰적인 ‘독자’를 길러내기 위한 미디어 교육, 미디어 텍스트의 ‘작가’로서의 의미생산자를 길러내기 위한 미디어교육 및 이를 위한 교사의 역할이라는 세 가지 차원에서 논의한다. 이러한 논의는 미디어 텍스트에 대한 (1) 누가 왜 소통하고 있는가 (2)어떤 종류의 텍스트인가 (3) 어떻게 생산된 텍스트인가 (4) 그 텍스트의 의미는 어떻게 알 수 있는가 (5)누가 텍스트의 의미를 받아들이는 가? (6)텍스트는 대상을 어떻게 재현하는 있는가와 같은 여섯 가지 측면을 고려하는 성찰적 문화교육이 되어야 하며, 이러한 관점은 전토적인 인쇄 매체를 통해 생산되는 언어 텍스트에도 일관되게 적용되어야 한다고 주장한다. This article explores the issue of media literacy in Korean language education, considering the changes in the ways of communication in the society. The main argument of the article is that the subject of Korean needs to reconsider its curriculum in order to teach the students how to communicate through diverse media, and therefore to move beyond the traditional, print-based literacy towards media literacy. The aims of media education as 'reflexive cultural education' are then discussed as making students active and reflexive 'readers' and 'writers' of media texts. Following this the article explores the role of the teacher of media education as providing the students with relevant competences of media criticism and production. The article also argues that the perspectives of reflexive cultural education to teach the complex aspects of media texts. I.e.. agencies, categories, technologies, languages audiences and representation - needs to apply to the teaching of the traditional print-based texts including literary texts.

Numerous previous studies, both in vitro and in vivo, have demonstrated that the cytotoxicity can be enhanced by the combination of chemotherapeutic agent and interferons(IFNs) in various types of cancer cells. We have previously reported that combined treatment of MKN-45, human gastric adenocarcinoma cells, with adriamycin(ADM) and recombinant human interferon-r(rh-IFN-r) increased in the cytotoxicity. In this study, the effects of combination timing of rh-IFN-r and ADM on the cytotoxicity against MKN-45 were investigated using MTT assay. MKN-45 was treated with rh-IFN-r and ADM in vitro on three schedules : Treat A ; rh-IFN-r and ADM were treated simultaneously, Treat B ; rh-IFN-r was treated 24 hours after the treatment with ADM, Treat C ; rh-IFN-r was treated for 72 hours and followed by the treatment with ADM. The survival of MKN -45 was inhibited by ADM dose-dependently. 102 and 103U/ml of rh-IFN-r significantly inhibited the survival of MKN-45(% survival : 35.1 ±-1.2% and 34.4 ±1.1% in Treat A and 42.5 ± 2.1% and 45.9-±2.5% in Treat C, respectively). However no difference in the survival was observed between 102 and 103U/ml of rh-IFN-r. Combined treatment with rh-IFN-r and ADM significantly augmented the cytotoxicity at low concentrations of ADM. Combined effects of rh-IFN-r and ADM were evaluated using IC30(,ag/ml) to ADM. IC30s of MKN-45 in Treat A, B and C at 102 U/ml of rh -IFN-r _ were 0.019 -?- 0.003, 0.045 :I:0.001 and 0.054 ± 0.012, respectively, while IC30 of MKN-45 treated with ADM alone was 0.052±0.004. IC30s of MKN-45 in ADM alone group, Treat A, Treat B and Treat C at 103U/ml of rh-IFN-r were 0.047 ±0.003, 0.004 -±0.001, 0.031 ±0.004 and 0.056 0.008, respectively. These results indicate IC30s of Treat A and B were significantly lower than those of ADM alone(p<0.05) and IC30s of Treat A was significantly lower than those of Treat B(p <0.01). IC30s of Treat C, however, were not different from those of ADM alone. From these results demonstrating that cytotoxic effects were increased by the combination of rh-IFN-r and ADM in the order, Treat A > Treat B> Treat C, it can be concluded that the simultaneous administration of rh-IFN-r and ADM may be the most effective method to combine these two therapeutic modalties.

자발적 예측정보공시의 정보효과

이원창,왕현선 충남대학교 부설 회계연구소 2001 회계논집 Vol.2 No.-

기업환경이 변화함에 따라 회계정보에 대한 수요가 증가하고 있다. 이에 따라 경영자의 자발적 예측정보공시도 증가하고 있다. 경영자의 자발적 예측정보공시는 기업의 수익성과 성장성을 판단하는 중요한 지침이다. 그러나 의사결정자들이 그러한 자발적 공시를 의사결정에 사용하는지는 정보의 신뢰성에 달려있다. 본 연구는 경영자의 자발적 예측정보공시가 투자의사결정에 사용되는지를 거래량변동을 가지고 검증하였다. 자본시장이 효율적이라면 자발적 예측정보 속에 내재된 정보위험에 따라 거래량변동은 다르게 나타날 것이다. 본 연구에서는 예측정보를 정보위험 수준에 따라서 3집단으로 나누고 집단간에 거래량반응에 차이가 있는지를 검증하였다. 추가적으로 비기대매출액 및 비기대이익의 크기가 거래량 변동에 영향을 미치는지도 검증하였다. 연구결과는 첫째, 경영자의 자발적 예측정보공시는 공시일 전후에 비정상적인 거래량증가를 가져왔다. 따라서 경영자의 자발적 예측정보공시는 자본시장에서 정보효과를 갖는다고 볼 수 있다. 둘째, 정보위험의 크기에 따른 경영자의 자발적 예측정보공시는 집단간에 거래량차이를 가져왔지만 통계적으로 유의하지 않았다. 셋째, 비기대매출액은 거래량변동에 영향을 미치는 변수로 확인되었으나 정보위험을 고려한 비기대매출액은 거래량변동에 영향을 주지 않았다. 이와같은 결과는 경영자들에게 자발적인 공시를 유도하여 정보의 비대칭을 감소시킬 것이다.

The purpose of this study was to compare the amount of calcium fluoride deposited on the enamel and dentin surface and to obtain information on the morphological change and crystallographic details of mineral deposition after 12,000ppm APF application in vitro. The bovine enamel and dentin blocks were randomly assigned to eight groups according to artificial caries lesion formation and difference of fluoride application time. The fluoride concentration and morphological characteristics on the treated enamel and dentin surface were investigated by using fluoride quantitative analysis and SEM. The powdered enamel and dentin of the intact bovine incisors were prepared for the X-ray diffraction analysis. The following results were obtained. 1. The amounts of KOH-soluble fluoride on the carious enamel and dentin surface after 24h APF application were higher than after only 5min APF application(P<0.05), but in the case of the sound enamel and dentin surface were similar after 5min and 24h application (P>0.05). The fluoride content was highly increased in the carious dentin as compared with sound dentin after APF application(P<0.05). 2. The caruous enamel surface after APF application, the demineralized enamel surface were recovered a more dense enamel surface and precipitation of crystal was observed a distintive surface layer of spherical globules of about 1 m diameter. In the case of the fluorided carious dentin surface, precipitation of calcium fluoride-like material was deposited both inside the dentinal tubules as well as in the intertubular regions. 3. The crystallographic structure of powdered enamel and dentin after 24h APF application had large crystallities of apatite and CaF2 diffraction peaks in the enamel as compared with dentin. The diffraction data collected from the 27.50-29.50(2) angular range of the powdered enamel, the (105) apatite, (225) apatite and (111) CaF2 peaks of the enamel crystallities were detected after 24h APF application.
