이동근,정휘철,김재욱 한국환경영향평가학회 2006 환경영향평가 Vol.15 No.4

Impacts of global warming have been identified in many areas including natural ecosystem.A good number of studies based on climate models forecasting future climate have beenconducted in many countries worldwide. Due to its global coverage, GCM, which is a mostfrequently used climate model, has limits to apply to Korea with such a narrower andchanges with a climate model fully reflecting characteristics of Korean climate. In this respect,this study was designed to compare and analyze the GCM and RCM in order to determine asuitable climate model for Korea.In this study, spatial scope was Korea for 10 years from 1981 to 1990. As a research method,current climate was estimated on the basis of the data obtained from observation at the GHCN.Future climate was forecast using 4 GCMs furnished by the IPCC among SRES A2 Scenario asfor the purpose of comparing data obtained from observation with GCM and RCM.As a result of this study, average annual temperature of Korea between 1981 and 1990 wasfound to be around 12.03˚C, with average daily rainfall being 2.72mm. Under the GCM,average annual temperature was between 10.22 and 16.86℃, with average daily rainfallCorresponding Author: Jae-Uk Kim, Graduate School of Environmental Studies, Seoul National University, San 56-1, Shillim-dong, Gwanak-gu, Seoul, 151-742, Korea Tel: 82-2-880-4885 E-mail: japa95@hanmail.net

학생들의 Zeno의 역설(반분 역설과 아킬레스 역설) 과제 해결 과정에 대한 연구 : 학생들의 표현을 중심으로

이동근 대한수학교육학회 2019 학교수학 Vol.21 No.2

This study is a follow-up study of Lee (2019) and Lee (2018). This study is a case study based on 12 teaching experiment data on three high school students(second). It focuses on the 8th to 12th teaching experiment data related to the research topic. In particular, it discusses how students who accept potential Infinite perspective when they encounter the half paradox and the Achilles paradox. And analyzed how students solve the paradoxical situation. This study can provide information on how students with a conceptual idea solve their concerns about reachability. This seems to be the basis for learning studies related to students' infinite concepts. 본 연구는 학생들의 극한 문제의 풀이 과정에서 ‘대수적 절차’와 ‘그래프를 이용한 방식’의 연결에 대한 이동근(2019)의 연구와, 다양한 형태의 등비급수 과제들에 대한 학생들의 표현에 대하여 연구한 이동근(2018)의 연구에 대한 후속 연구로서 학생들의 ‘도달 가능성’에 대한 표현을 구성적 관점에서 분석한 연구이다. 본 연구는 세 명의 고등학생들을 연구 대상으로 하여 진행한 12차시의 교수실험 자료에 근거한 사례연구이며, 연구주제와 관련된 8차시에서 12차시까지의 교수실험 자료를 중심으로 논하고 있다. 특히 가무한 관점에서 무한을 받아들이는 학생들이 반분 역설과 아킬레스 역설을 접하였을 때 어떻게 받아들이는지와 또 어떻게 역설적 상황을 해결해가는지에 대하여 학생들의 표현을 중심으로 분석하였다. 본 연구는 가무한 개념을 가진 학생들이 ‘도달 가능성’에 대한 문제를 어떻게 해결해가는지에 대한 정보를 제공할 수 있으며, 이는 학생들의 무한 개념과 관련된 학습 연구에 기초가 될 수 있을 것으로 보인다.

고등학교 수학 수업에서 과정 중심 평가 수업을 위한 피드백 중심 수업 자료 개발에 관한 연구

이동근,한창훈 한국수학교육학회 2022 수학교육논문집 Vol.36 No.1

This study is a study that developed class materials that can apply Process-Focused Assessment to classes by paying attention to feedback using teacher learning community programs centered on teachers belonging to the same school in the field. In particular, this study was conducted with the aim of developing class materials applicable to actual classes. At this time, We thought about how to provide appropriate feedback when applying course-based evaluation in school field classes. It was conducted according to the procedure of data development research by Lee & Ahn(2021). As for the procedure of data development itself, an evaluation plan was established by establishing a strategy to reconstruct achievement standards and confirm understanding based on curriculum analysis. Next, an evaluation task, a scoring standard table, and a preliminary feedback preparation table were developed. In addition, based on these development materials, a learning guidance plan that can predict scenes when applying actual classes was developed as a result. This study has value as a practical study that can contribute to providing a link between theory and field schools. It is also meaningful in that it considered how the teacher would grasp when to provide feedback in performing rocess-Focused Assessment. Likewise, in providing feedback by teachers, it is meaningful in that it reflects in the data development how to prepare in advance and take classes according to the characteristics of the subject. Finally, it seems that the possibility of field application can be improved in that the results of the 4th class developed in this study are presented in a form applicable to the class directly in the field. 본 연구는 현장의 동일교 소속 교사들을 중심으로 교원학습공동체 프로그램을 이용하여 피드백에 주목하여 과정 중심 평가를 수업에 적용할 수 있는 수업 자료를 개발한 연구이다. 특히 실제 수업에 적용 가능한 수업 자료를 개발하는 것을 목적에 두고 진행한 연구이다. 이때 학교 현장 수업에서 과정 중심 평가를 적용할 때 어떻게 적절한 피드백을 제공할 것인지 고민하였다. 이동근, 안상진(2021)의 자료 개발 연구의 절차를 따라 진행하였으며, 자료 개발 자체의 절차는 교육과정 분석에 근거한 성취기준의 재구성과 이해도 확인 전략을 수립하여 평가계획을 수립하였다. 다음으로 평가과제와 채점 기준표 및 사전 피드백 준비표를 개발하였다. 또한 이들 개발 자료들에 근거하여 실제 수업적용 시의 장면을 예상할 수 있는 학습 지도안을 결과물로 함께 개발하였다.

이동근,문철,김장현 원광대학교 생체재료·매식연구소 1996 원광생체재료·매식 Vol.4 No.3

This study has demonstrated the efficacy of arthrocentesis of upper temporomadibular joint (TMJ) compartment in cases of severe pain and limited maximum mouth opening (MMO) in traumatic hemarthrosis of TMJ. Thirteen patients complaining of severe pain and limited MMO were treated by irrigation of the upper compartment of the affected TMJ with lactated Ringers solution. This treatment was found to be effective in reestablishing normal mouth opening and relieving pain within I week in postoperative. It is suggested that arthrocentesis simple, less invasive, inexpensive, and highly efficient procedure, which can be performed under local anesthesia, is used in traumatic hemarthrosis cases with severe pain and limited MMO.

이동근,장양욱,문우성,김달식,최호열 의과학연구소 1991 全北醫大論文集 Vol.15 No.1

This experimental study was carried out to investigate the effect of dimethyl sulfoxide on the functional and morphological changes of actue ischemic renal failure. Following unilateral nephrectomy, acute ischemic renal failure was induced by clamping of renal artery of the remaining kidney and reperfused afrer one hour. Immediately after reperfusion, experimental group received 5ml of 20% solution of dimethyl sulfoxide intrave- nously at a constant rate(0.5ml/min.) using infusion pump, and control group received an equal volume of ph- ysiologic saline. On the 1, 3 and 5 days after operation, serum concentrations of BUN and crearinine were detected by automated chemical analyzer. Histological(hematoxylin-edsin, periodic acid Schiff, trichrome, reticulin and epon-toluidine blue stains) and enzyme histochemical(adenosine triphosphatase, succinic dehydrogenase, and acid phosphatase stains) studies were also performed. The following results were obtained. 1. Serum BUN and creatinine levels were significantly increased in control group proportional to the postope- ration course. But there was no increase in dimethyl sulfoxide treated group except slightly elevated BUN le- vel of 1 day group after operation. 2. The control group exhibited prominent morphological changes including irregular dilatation of tubules, va- cuolar degeneration, detachment and necrosis of proximal tubular epithelium, numerous hyaline casts in distal cation of proximal tubular epithelium. And these morphologic changes were increased progressively in severity proportional to the post-operation course. However, dimethyl sulfoxide treated group exhibited slight morpholo- gical changes including hyaline casts in tubules and vascular congestion except more prominent changes in 1 day group after operation. 3. On enzyme histochemical finding, adenosine triphosphatase, succinic dehydrogenase and acid phosphatase activities were diminished in control group, but not in dimethyl sulfoxide treated group.
