The purpose of this thesis is examine empirically the influence on student`s leaning effects by the psychological condition and environmental factor before class. For the purpose, 402 undergraduates, currently majoring in Dance in the universities around Seoul and National Capital region, were selected by the meathos of stratified cluster random sampling. And, the data taken from the 402 out of that of them were used in this thesis. The method adopted here for collecting the data on the psychological condition is the questionnaire translated and standardized from the State-Trait anxiety Invertory, originally invented by Spieberger in 1972, by Jungtak Kim. And, the method adopted for measuring the environmental factor is the scale of empirica lresearch on athletes by Passer and Seese in 1981, and it is slightly revised and supplemented for the purpose of the thesis. The statistic methods used for the analysis of the data are factor analsis, descriptive analysis, one-way ANOVA, and standard multiple regression analysis. With all above mentioned research methods and procedure, the conclusion drawn from the analysis for the data on the influence on learning effects by the psychological condition and environmental factor before class is as following: First, there are significant differences in the environmental factor, and learning effects, which are set up according to changing causes, among groups of students. And, in the environmental factor, the group of older and more experienced studendts and those majoring in ballet tend to show the gap in the interpersional relationship. And, more experienced group and those graduated from the Art high school show high learning effects. Second, the psychological and environmental factor affact learning effects. Second, the psychological condition and environmental factor affect the learning effect. In the psychological condition, both positive and negative psychological conditions affect it. and in the environmental factor, the interpersonal relationship affects the learning effect. In other word, the higher the positive psychological condition is or the lower the negative psychological condition is, the higher learning effect is. Moreover, high interpersonal relationship results in the high lear

A comparative study was undertaken to evaluate the contact Neodymium : yttrium aluminum garnet(Nd : YAG) laser system for vascular anastomosis of small caliber blood vessels(diameter 0.5-1.2mm) in the animal model. In this study 40 femoral arteries and 40 femoral veins of Sprague-Dawley rats were anastomosed by contact laser assisted microvascular anastomosis(LAMA) utilizing 3 stay sutures which were placed 120 degrees apart and the intervals welded with contact Nd : YAG laser unit, conventionally sutured anastomosis(CSA) served as controls. The time needed for vascular anastomosis, patency rate (immediate postoperative, postoperative 2nd day, postoperative 1 week, postoperative 4 week), gross and microscopic evaluations were compared to conventional microsurgical suture technique. The results are as follows : (1)Post-operative patency rate was 82.5% for femoral artery and 75% for femoral vein by contact LAMA technique compared to 90% and 75% by CSA technique at post operative 4 weeks. (2)Less time-consumed for arterial anastomosis by 6 minutes 23 seconds and venous anastomosis by 8 minutes 55 seconds with contact LAMA technique compared to CSA technique. (3)Grossly almost complete healing had taken place by post-operative 1 week by contact LAMA technique. (4)Aneurysm formation was 5% for femoral artery and 15% for femoral vein by contact LAMA technique compared to 5% and 10% respectively by CSA technique. (5)Microscopically, re-endothelization was complete by post-operative 7th day by contact LAMA technique. There was less medial hypertrophy and hyperplasia and also less inflammatory response compared to CSA.

Amyloidosis is a disease resulting in deposition of amyloid in the body. The disease can be either primary or secondary. The amyloidosis of urinary bladder is more usually affected by primary amyloidosis and also very rare. The patient with primary amyloidosis of the bladder usually presents with gross hematuria. The amyloidosis resembles bladder cancer in cystoscopy. It can be confirmed by biopsy. The treatment consists of medication (e.g., steroid, antitumor agent, cholchicine, DMSO) and/or transurethral resection. The standard treatment is mephalan and prednisolone. A 49-year-old man complained of recently developed gross hematuria without abdominal pain. We examined urinary bladder cystoscope for gross hematuria. It revealed small bulging mass on trigone are a of bladder. Therefore we did bladder biopsy. Finally, it revealed bladder amyloidosis. The patient was improved by medication (mephalan 2mg and prednisolone 1 mg/kg po daily). We report an unusual case of amyloidosis involving bladder.

학교 교육에서 평가는 교육목표 달성 확인 및 교수 계획 수립에 중요한 역할을 한다. 따라서 학생들의 학업성취도 평가는 높은 내용타당도를 가지고 있어야 한다. 즉, 학업성취도 문항은 수업목표에 비추어 적절하고 학습한 내용을 포괄할 수 있어야 한다. 학교 현장에서 평가 문항의 타당도는매우 중요한 반면, 실제 학교에서 사용되는 고등학교 화학 과목의 평가 문항들이 어느 정도 내용타당도를 가지고 있는지 조사되는 경우가 거의 없다. 따라서 이 연구에서는 학교현장에서 실시되는화학 학업성취도 평가문항이 행동차원과 내용차원에서 어느 정도의 내용 타당도를 가지는지 분석하고자 하였다. 이를 위한 연구의 대상은 제7차 교육과정에 의하여 개발된 동일한 화학Ⅰ 교과서를 교재로 사용하고 있는 5개 학교의 ‘물’ 단원에 대한 1학기 중간고사 평가문항이었다. 내용타당도 분석을 위한 과정은 첫째, 교과서와 교사용지도서에서 34개의 수업목표를 내용차원과 행동차원으로 이원 분류하였다. 둘째, 5개 고등학교의 평가문항에서 121개의 평가문항을 행동차원과 내용차원으로 이원 분류하였다. 셋째, 행동차원과 내용차원별로 각각 수업목표와 평가목표의 비율차 검증을 하였다. 연구 결과, 5개 학교에서 사용된 학업성취도 문항은 행동차원에서의 내용타당도는낮았지만 내용차원에서의 내용타당도는 높은 것으로 나타났다. 이는 고등학교에서 실시하는 학업성취도 평가에 있어서 행동차원의 내용타당도를 높이는 노력이 좀 더 필요하다는 것을 시사한다. 특히 행동차원 중 분석력, 종합력, 평가력 등 고등정신기능을 기르는 평가 문항의 개발에 노력을기울여야 한다. 이 연구를 통해, 평가 문항 제작에 대한 교사들의 전문성을 높이기 위해 다양한연수나 교육 프로그램이 개발될 필요가 있음을 알 수 있다. In school education, the evaluation plays an important role for the accomplishment ofeducational goal and for the planing of education. Thus, the achievement evaluation itemshould have high validity. The achievement evaluation items should appropriate for theeducational goal and include all the learning contents. Although the validity of achievementevaluation items is very important, little research was performed on how much the evaluationitems of high school chemistry course really have the content validity. Therefore, in this study we analyzed the validity of the chemistry achievement evaluation items used in schools in thedimension of behavior and content. For this, 5 different high schools were selected that used the same publisher's chemistry I textbook, and the middle semester achievement evaluation items were gathered. First, 34 instructional objectives were classified into the behavior domain and the content domain from the 'water' chapter in the textbook and the teacher's guide. Second, 121 evaluation items were classified into the behavior domain and the content domain. Third, the analysis of the ratio difference method were performed between the instructional objectives and the evaluation objectives. From the results, it was found that content validities of the behavior domain were low, but those of the content domain were high. These results implies that more effort should be paid to raise content validities of the behavior domain in achievement evaluation of high schools. Especially, the test items should be developed on the high level thinking skill such as analysis, synthesis, and evaluation. This study tells it is necessary to develop in-service teacher education program to raise the professionality of teachers on the evaluation items.

중학교 화학 분야의 오개념 조사에 사용된 설문지의 문제점을 밝혀, 학생들의 정확한 오개념 조사를 위한 바탕을 마련하고자 한다. 기존의 중학교 화학 분야에 대한 오개념 조사 설문지가 연구 대상 학생들에게 잘못 사용되고 있었으며, 문항 내용 자체에도 오류가 있었음을 지적하고자 하는 것이다. 선행 연구들의 분석 결과들이 오개념이 아니라 무개념임을 확인하기 위하여 중학교 1학년 학생 182명을 대상으로 두 종류의 설문지 A와 B를 투입하여 조사하였다. 설문지 A는 오개념 연구를 위해 선행 연구들에서 사용한 문항들로 이루어진 것으로, 이를 투입한 결과를 선행 연구들의 결과들과 비교하기 위한 것이다. 그리고 설문지 B는 설문지 A에서 응답한 학생들의 구체적인 생각을 알아보기 위하여 새롭게 개발한 것이다. 설문지 A를 통해 얻은 결과와 선행 연구들에서 얻은 결과들을 비교할 때, 전반적으로 일관성이 없게 나타났으며, 중학교 1학년 학생들의 주관식 정답률이 객관식 정답률에 비해 매우 낮게 나타나는 공통점은 있었으나, 문항 자체의 오류들이 발견되었다. 설문지 B를 통해 학생들의 생각을 알아본 결과, 설문지 A에서 과학적 개념과 오개념으로 분류된 학생들 중에서 무개념으로 판단된 경우가 많았다. This study was to clarify the problems of questionnaires related to misconception researches of middle school chemistry and to prepare a ground for the correct misconception research for students. For these purposes, the questionnaires of the misconception researches related to chemistry in middle school were analyzed, and the mistakes of the questions which were used in 7th grade students were found, based on a definition of misconceptions in this study. Also, the errors in contents of the questionnaires were indicated. The results of the analysis revealed that most of the 7th grade students did not have misconceptions contrary to some of the previous researches conclusions. They only had no conceptions related to the contents. In order to support this analysis, two different questionnaire sets (questionnaire set A and B) for 182 7th grade students were used. After obtaining similar results to those of the previous researches by the questionnaire set A, the students' thoughts were examined by the questionnaire set B. From the results of this study, the correct answer rates of subjective questions were very low compared with those of objective questions in the questionnaire set A for 7th grade students. It was hard to find consistency among the results of the researches using the questionnaire set A. And many contents of the questions consisted of the questionnaire set A were not consisted with a definition of misconceptions. There were errors in the contents of the questions, too. The students classified as the having-science-concepts group and the having-misconceptions group by the questionnaire set A were classified as the having-no-concepts group by the questionnaire set B.

중학교 과학영재 담당교사의 PCK 요소의 특징과 관련성

김선경,민희정,방은정,백성혜 韓國英才學會 2011 영재교육연구 Vol.21 No.4

중학교 과학영재 담당교사의 수업을 관찰하여 Pedagogical Content Knowledge(PCK)의 요소 를 분석하고, 요소간의 관련성을 알아보았다. 연구 대상은 대도시 지역의 중학생 대상 영재교 육원에서 과학을 가르치는 교사 4명이었으며, 전공은 각각 물리, 화학, 생물, 지구과학이고 2 명은 전임교사, 2명은 겸임교사였다. 또한 전임교사들은 영재학생들만 가르쳤고, 겸임교사들 은 보통 일반학생들을 가르쳤고, 특별히 주 1회 영재학생들을 가르쳤다. 수업관찰, 반구조화 된 인터뷰를 실시하였으며, 문서자료를 수집하여 질적으로 분석하였다. 연구 결과, 과학영재 담당교사의 PCK 요소의 몇 가지 특징이 나타났다. 교사들의 과학교수지향은 PCK의 요소들 과 긴밀하게 상호작용하고 있었다. 교사들의 교육과정지식은 교사에 따라 상이했지만, 학습 유형의 선택은 교사의 영재 교육 및 수업의 목표와 관련되어 있었다. 또한 이러한 교육과정 지식은 학생에 대한 이해의 영향을 받았다. 교사들은 교육과정지식과 학생에 대한 이해에 따 라 수업에서 서로 다른 교수전략을 사용하고 있었다. 또한 PCK의 요소들의 관계는 밀접했으 며 방향성을 가지고 있었다. 이러한 연구결과를 바탕으로 PCK의 요소와 관계성을 설명하기 위해 사면체 모델을 제안했다. In this study, we analyzed the characteristics of Pedagogical Content knowledge(PCK)'s components through actual course of teachers of science gifted students in the middle school. For this study, four middle school science teachers of gifted students belonging to the gifted education professional organizations in a metropolis were selected, each of them was physics, chemistry, biology, and earth science teacher. Two of them were full-time teachers to teach only gifted students and two were part-time teachers who had taught general students in ordinary time and specially had taught the gifted students once a week. Qualitative data were collected through classroom observations, interviews, and documents. As a result, some unique characteristics of PCK's components were identified. The teachers' orientations to teaching science were closely correlated with PCK's components. The teachers' knowledges of science curriculum were different individually. But the decisions about type of teaching(acceleration or enrichment) were connected with the objectives of gifted education and lesson objectives. Also, the teachers' knowledges of science curriculum were influenced by the knowledge of students' understanding. Teachers used different instructional strategies according to the knowledge of science curriculum and the knowledge of students' understanding. We found that PCK's components were so closely connected and could show the direction of relationships among those PCK's components. We suggested teachers' PCK model which was named "Tetrahedron Model of PCK", to explain the characteristics and relationships of PCK's components.

배경 : 골수염의 진단에 있어 Technetium-99m을 이용한 삼상 골스캔(Tc-99m MDP스캔)은 단순방사선 검사상 정상소견을 보이는 경우에 쓰이는 1차적 검사로 매우 높은 민감도를 보인다. 그러나 Tc-99m MDP 스캔은 골절이나, 정형외과적 삽입물, 신경병적 관절병변과 같이 뼈의 재형성이 증가되는 상황에서도 양성소견을 보여 특이도가 낮은 단점이 있다. 이러한 단점을 보완하고자 골수염의 진단에 있어 Tc-99m HMPAO 백혈구 스캔의 유용성을 알아보고자 하였다. 대상 및 방법 : 골수염이 의심되어 Tc-99m HMPAO 백혈구 스캔을 시행했던 15명의 의무기록을 후향적으로 분석하였다. 골수염의 확진은 임상관찰 소견과 배양검사 결과와 병리소견을 기준으로 하였다. 결과 : 골수염의 진단에 있어 Tc-99m HMPAO 백혈구 스캔의 민감도와 특이도는 각각 100%와 78%였고 Tc-99m HMPAO 스캔의 경우는 100%와 18%였다. 가장 흔한 원인균은 methicillin-resistant S. aureus였다. Tc-99m MDP 스캔에서 양성소견을 보였던 환자중 3명의 환자가 Tc-99m HMPAO 백혈구 스캔에서 음성 소견을 보였으며 이 환자들은 추적관찰상 골수염이 없는 것으로 확인되었다. 결론 : Tc-99m HMPAO 백혈구 스캔은 골수염의 존재를 진단하는데 있어 민감도와 특이도가 높으며, 특히 뼈의 재형성이 증가되어 Tc-99m MDP 스캔의 특이도가 낮게 나타나는 상황에서 유용하리라 사료된다. Background Three phase bone scintigraphy, performed with technetium-labeled diphosphonates (Tc-99m MDP scan), is the very sensitive radionuclide procedure of choice for diagnosing osteomyelitis. But, Tc-99m MDP scan is less specific when bone remodeling is increased. To overcome this limitation, we evaluated the diagnostic value of technetium-99m hexamethylpropyleneamine oxime (HMPAO) labeled leukocyte scan in osteomyelitis. Methods : We retrospectively reviewed 15 patients with suspected osteomyelitis who performed Tc-99m HMPAO labeled leukocyte scan. The diagnosis of osteomyelitis was based on clinical course and bacterial culture, and pathologic findings. Results The sensitivity and specificity of Tc-99m HMPAO leukocyte scan was 100% and 78%, and those of Tc-99m MDP scan was 100% and 18%, respectively. The most common organism was Methicilein-Resistant S. aureus. Among the patients that showed persistent accumulation on Tc-99m MDP scan, three patients showed no uptake on Tc-99m HMPAO leukocyte scan and these patients were confirmed that had no osteomyelitis. Conclusion : Tc-99m HMPAO leukocyte scan is a useful test for determining the presence or absence of osteomyelitis, especially under condition that bone remodelin is increased.
