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

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.

This experimental study was carried out to investigate the effect of dimethyl sulfoxide on the experimentally induced ischemic injury of skeletal muscle. The ischemic injury of the skeletal muscle was induced by the atraumatic clamping of the common iliac artery, and then reperfused after 1 hour and 5 hours, respectively. Immediately after reperfusion, experimental group were received 5㎖ of 20% solution of DMSO intravenously with a constant rate(0.5㎖/min) using infusion pump,and control group were received an equal volume of physiologic saline. histological and enzyme histochemical stains for H&E, trichrome, PAS, SDH and reversed myosin-ATPase on the flash-frozen sections of soleus muscle were performed on the 24hours after operation. The following results were obtained. 1.The soleus muscle ischemic for 1 Hour revealed only focal edema of the endomysium and perimysium. And the muscle ischemic for 5 hours exhibited pyknosis and focal disappearance of the sarcolemmal nuclei, flocculation of the sarcoplasm, endomysial and perimysial edema, and discoidal degeneration of muscle fibers. But there was no difference between the control and DMSO-treated group. 2.The total number of muscle fibers per unit area in the group of 5 hours ischemia was decreased in comparison with the normal rats. But the difference between the control and DMSO-treated group was not significant. 3.The proportion of muscle fiber types in both ischemic groups equally showed decrease in S-type onPAS stain. But there was no difference between the control and DMSO-treated group. These experimental results demonstrated that dimethyl sulfoxide revealed no protective effect against the acute ischemic injury of the skeletal muscle.

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks,4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.

20세기 초엽에 외국에서는 개화문명이 한창 발전하고 있을 즈음에 우리나라는 36년간이라는 긴 세월을 다른 민족의 지배를 받고 있었으니 정치적, 사회적, 문화적으로 고찰해 볼 때 지대한 후퇴가 아닐 수 없다. 한국문화 말살정책으로 인해서 민족의식을 유지해 오던 우리의 문자마저도 빼앗기고 민족의 거울이 되어오던 우수한 고전문학도 사라져 가기 시작하였고 드디어 문학적으로 백지화 된 가운데 해방을 맞이 하였던 것이다. 더러는 우리 고유문화를 찾으려고 애를 썼지마는 밀물같이 밀려오는 새로운 외국문화에 밀려 우리는 외국의 모방에 지나지 않는 모방문학을 완성하였다. 높은 Building을 지을 때 기초가 튼튼해야 그 building이 오래동안 유지될수 있겠지만 우리문학은 그렇지 못함이 유감이다. 그렇다고 그 모방문학을 완전 무시하자는 생각은 조금도 없다. 단지 기초부분에 밑거름을 주어서 좀 더 착실한 우리문학을 만들어 보고싶은 것이다. 밑거름으로는 우리의 고전문학이 중요한 질서의 위치를 차지할 것이고 우리들 스스로의 참신한 창작이 인산의 역할을 하여 굳굳한 전통을 살찌게 할 것이고 다음으로「카리」에 비유되는 외국의 모범적이고 우수한 문학을 수입하여 우리문학의 부족한 면을 보충하여 아름답게 가꾸어진 우리문학을 만끽하고 장려하여서 세계문단에 참여할 수 있는 폭넓은 발전과 전진을 촉구해야 할 것이다.

지금까지 개발된 구조해석용 프로그램이 고층건물의 구조해석에 적합하지 못함을 개선하여 고층건물의 특성을 살린 구조해석을 할 수 있는 컴퓨터 프로그램을 개발함으로써 앞으로 세워질 고층건물을 더욱 안전하고 경제적이 되게 설계 할 수 있도록 한다. 일반적인 방법에 의한 결과와 여기서 보여 준 방법에 의한 결과를 비교해 보면 15층 이의 건물을 설계할때는 일반적인 방법은 상당히 큰 오차를 가진 계산치를 얻게 하지만 여기서 제시한 새로운 방법은 실제 문제와 대단히 가까운 좋은 결과를 가져다 준다는 것을 알 수 있다. 이 새로운 방법은 증축을 예상하는 구조물의 설계이도 적용이 될 수 있으므로 그 활용범위는 대단히 넓을 것이다. Most of the strctural analysis programs are developed on such hypothesis that the hole building is built up in one step and the loading conditions are applied after the completion of the frame. But a high-rise building is built up not in one step but in as many steps as it's stories. Accordingly the dead loads must be applide through all the construction steps, while the live loads may be applied after the completion fo the frame. Here, we propese a new computer program for structural analysis of high-rise buildings. Some of the important points in this new program are as following. 1.Frame is not built in one step but in so many steps as it is. 2.Dead loads are applied through all the steps and makes the frame to deform. 3.After deformation, next step of construction and loadings are succeeded. Comparing results from this new program with that of others, we can make such conclusion that in structural design for high-rise buildings of about 15 stories of more, we design more economic and safe buildings by using this new program.

This report is a clinical study or 76 cases of nontoxic thyroid nodules which were treated at the Department of Surgery of Chosun University Hospital during last 6 years from January, 1973 through December, 1978. The results were as follows. 1) Age distribution was 18 to 57 years and the most frequent incidence was in the 5th decades as 34.2%. 2) The male to female ratio was 1:18. 3) The duration of symptom in most of cases before admission was 1 year. 4) A palpable mass was the chief complaint in all patients. Dysphagia, palpitation and headache were common complaints. 5) In thyroidal uptake of radioactive iodine, 66 cases(86.8%)were normal range, 6 cases (7.9%)were lower than normal range, 4 cases(5.3%)were higher than normal range. 6) In the radioiodine scanning, 74 cases(97.4%)were cold nodules, 2 cases(2.6%)were warm nodules. 7) Of the 66 cases of the benign disease, adenoma was the most common, about 81.5%. In the 10 cases of the malignant disease, papillary adenocarcinoma was most common, about 60%. 8) The operative technique used in most case or benign disease was complete lobectomy. Total thyroidectomy when malignant was confirmed. 9) The postoperative complications were recurrent laryengeal nerve paralysis (4), hematoma and wound infection (2), transient parathyroid deficiency (2)
