정현철,류춘렬,채유정 韓國英才學會 2012 영재교육연구 Vol.22 No.2

The purpose of this study was to investigate the current status of R&E programs in gifted high schools/science high schools and to provide suggestions for the better program. The sample included 21 R&E coordinators in the gifted high schools and science high schools. They filled out the survey, asking about the R&E program; then, the researchers interviewed the coordinators based on the answers of the survey. The results are as follows: 1) The R&E guidelines and related materials were not enough to use. 2) At the planning step, students and the mentors received were provided a little information, such as ethical issues, students' information, the roles of mentors/ students, mentor's research interest areas and products, etc. 3) At the research step, 80% of the schools had the monitoring process but the details were not written and saved. 4) At the evaluation step, the rubric of the product evaluation existed; the rubric of performance process were established by half of the schools. 5) At the closing step, 100% of the schools had the final product materials; the results of the evaluation and the information of the mentors were saved by 2/3 and 1/3 of the schools, respectively. Discussions and suggestions were included for the better R&E programs. 본 연구에서는 R&E 프로그램의 운영지원현황 및 실태를 알아보기 위하여 R&E 운영단계를 준비-계획-실행-평가-종료 5단계로 구분하여 조사 및 분석이 이루어졌다. 총 18개 과학고와 3개 영재학교 R&E 운영담당자들이 본 연구에 참여하였다. 2010년 12월, 전수조사를 목적으로 각 학교에 설문지를 배포하였으며, R&E 운영담당자 21명(100%)이 설문에 응답하였다. 주요 결과는 다음과 같다. 첫 번째, 준비단계에서 학생의 R&E 수행지침은 적절히 이루어지지 않고 있었으며, 운영을 위해 참고할 수 있는 자료도 매우 부족한 것으로 나타났다. 두 번째, 계획 단계에서 지도자를 대상으로 윤리적인 문제, 참고자료, 학생배경 특성 등에 관한 안내가 적절히 이루어지지 않고 있었으며, 학생들에게 지도자의 의무와 역할, 연구정보 및 업적 등에 대한 정보제공이 충분히 이루어지지 않고 있었다. 세 번째, R&E 실행단계에서는 80%의 학교가 수행 점검을 실시하고 있었으나 세부적인 점검내용에 대한 기록은 이루어지지 않고 있었다. 네 번째, 평가단계에서 산출결과의 평가기준은 모든 학교가 갖추고 있었으나, 수행 과정에 대한 평가기준은 약 절반의 학교만 가지고 있었고, 평가비율에 발표내용과 결과보고서 비율이 높게 나타나 평가가 ‘결과’에 많은 비중을 두고 있는 것으로 나타났다. 마지막으로, 종료단계에 결과자료집은 100% 보관되고 있었으나 평가결과는 2/3 학교가, 그리고 지도교수 정보는 약 1/3의 학교만이 보관하고 있는 것으로 나타났으며, 학생관찰 내용 및 면담자료도 비교적 잘 보관되지 않는 것으로 나타났다. 이와 같은 결과를 바탕으로, 효과적인 R&E 프로그램 운영을 위한 운영개선 지원방안을 제시하였다.

이 연구의 목적은 제 6차 교육과정에 의한 중학교 1학년 과학 교과서 분별 증류 실험의 문제점을 파악하고, 중학생들이 분별 증류 실험을 능률적으로 수행할 수 있는 실험 방법을 제시하고자 하는 것이다. 이를 위한 첫 번째 단계로서 현재 사용되고 있는 8종의 과학 교과서를 분별 증류 실험 장치와 액체 혼합물의 종류에 따라 6가지로 분류하였다. 두 번째 단계로서 액체 혼합물을 가열 방법에 따라 직접가열과 물 중탕 가열로 나누어 교과서 실험과정에 따라 같은 실험을 세 번 실시하였다. 세 번째 단계로서 실험 결과의 문제점을 해결하기 위한 대안 실험을 실시하였다. 대안 실험에서는 알코을 램프로 직접가열 하는 방법과 기름 중탕으로 가열하는 방법, 그리고 가열 맨틀을 사용하여 가열하는 방법을 사용하였다. 연구결과, 가지 달린 둥근 플라스크를 직접 가열하는 실험 결과가 가지 달린 시험관을 물 중탕으로 가열하는 실험 결과보다 이론적인 결과에 근접하였다. 그리고 가지 달린 둥근 플라스크를 직접 가열하는 실험에서 플라스크 윗 부분을 보온해 주는 실험이 보온하지 않은 실험보다 실험 결과가 더 나았다. 대안 실험에서는 액체 혼합물의 증류 온도 증가를 보면서 가열 맨틀의 가열 온도를 을려 준 실험의 결과가 이론적인 결과에 가장 가까웠다. 이러한 연구 결과로부터 가지 달린 시험관을 물 중탕으로 가열하는 분별 증류 실험 장치는 탐구실험 수업에 부적절한 것이므로 개선이 요구되며, 중학교 과학실 여건을 고려할 때, 액체 혼합물의 증류 온도 증가를 보면서 가열 맨틀의 가열 온도를 변화시키는 분별 증류 실험이 가장 능률적인 방법임을 알 수 있었다. The purpose of this study was to find out the problems on the fractional distillation experiments in the middle school science textbooks based on the 6th curriculum and to suggest an efficient experiment method for the middle school students. The first step was the classification of the experiments in 8 science textbooks according to heating apparatus and liquid mixtures. The second step was doing each experiment 3 times followed by the experimental process in the textbooks. The third step was developing the alternative experiments for solving the problems found in the second step. The heating method used in the alternative experiments were direct heating, oil bath, and heating mantle. The results of the second step showed that the direct heating experiment of branched round flask was more close to the theoretical prediction than the experiment of water bath heating of branched test tube. Also the direct heating experiment of thermally insulated branched round flask was better than the result of the experiment which was not insulated. The results of the third step showed that the experiment using heating mantle regulated heating power by observing the temperature of distillate gave the closest result to the theoretical prediction. From the above results, it is concluded that the experiment using branched test-tube with water bath heating is not adequate for the fractional distillation and an alternative experiment using insulated branched round flask with heating mantle regulated heating power during experiment is recommended.

Bronchopleural fistula and chronic empyema are the difficult problems in the thoracic surgery field. We experienced 3 cases of chronic empyema and complicated bronchopleural fistulas treated with muscle flap and concomitant thoracoplasty. The causative primary diseases were pulmonary tuberculosis and bronchiectasis. All the three cases have failed to control the chronic empyema and bronchopleural fistula with conventional method such as closed or open drainage and Eloesser flap after lobectomy. The unresponsive infection on bronchopleural fistula and pleural space was well controlled after muscle flap with thoracoplasty. Complete decortication, closure of bronchopleural fistula as much as possible and coverage of closed fistula with good vascularized tissue are the essential factors for the success of operation on chronic empyema and bronchopleural fistula. The results of operations were satisfactory and the respiratory function was well preserved or improved in one patient. But, the contour of chest wall was deformed in patient with extensive concomitant thoracoplasty.

Prostaglandin 합성을 촉진하는 새로운 강압약인 cicletanine의 강압효과를 진료실 혈압과 24시간 활동혈압으로 평가했을 때 상당한 차이를 보여 그 이유를 검토해 보았다. To evaluate antihypertensive effect of cicletanine with both clinic and ambulatory blood pressure monitoring, 10 male hypertensive patients were administered cicletanine, a new antihypertensive stimulating prostaglandin synthesis, in 100∼200 mg daily for 12 weeks. The following were the results. 1.Mean of clinic BP decreased from 161/98 mmHg to 153/98 mmHg. 2.Mean of ambulatory BP changed from 140/91 mmHg to 153/99 mmHg. 3.Side reactions were mild, namely indigestion and constipation. 4.Discrepancy between clinic and ambulatory BP were discussed. In conclusion cicletanine revealed slight antihypertensive effect with clinic blood pressure, but failed to confirm it with ambulatory blood pressure.

In this study, the pressure drop and velocity profile were measured in longitudinally finned annulus. The test specimens were a round rod of 38㎜diameter with no fin, a rod a 40㎜ with 6 fin, a rod of 40㎜ with 8 fin, and a rod of 50㎜ with 8 fin. The fin thickness was 3㎜ and the fin height was 5㎜. The specimen was installed in a tube of 76㎜ inner diameter. For the round rod with no fin, the pressure drop data were well predicted by Blasius correlation, and the velocity profile was very close to the Nikuradse's non-dimensional velocity profile. For finned rods, the pressure drop of 8 fin rods was well predicted by Blasiue correlation. However, the correlation slightly under-predicted 6 fin data. The maximum velocity points in the finned annulus were circumferentially uniform except for the fin top position. Quarmby's equation [Eq.14] predicted the maximum velocity points excellently.
