Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

Optical microscope, SEM (Scanning Electron Microscopy) and fluorescent microscope were used for qualitative and morphological studies of the attached biomass on PE (polyethylene) substratum under anaerobic condition. It was shown by the observation of optical microscope that the initial attachment of biomass began in crevices of the surface of PE. The shape and structure of the attached biofilm could be observed by SEM photographs, but species of bacteria were and methanogens were not classified. A large number of methanogenic bacteria were identified on the surface of PE substratum by fluorescence under 480㎚ of radiation. It was estimated that methanogenic bacteria was also related to initial attachment of biomass under anaerobic condition.

The lab-scale anaerobic continuous reactor which was filled with the sludge of anaerobic digestion from Suyoung wastewater treatment plant was operated by feeding of various concentrations and flow rates. This experiment indicated that more than 6,870 ㎎COD/L of substrate concentration was required to promote good metabolism and growth of anaerobic biomass. And increasing loading rate slowly was also required in order to treat substrate of higher concentration and higher loading rate. The substrate concentration of about 10,000 ㎎COD/L was adequate to generate biogas efficiently. The pH was sharply decreased at the onset of higher loading rate, but the pH was restabilized soon at 8. During the experiment, the amount of the attached biomass was kept constant.

고등학생 생물 '물질대사' 단원에서 협동학습의 효과 : STAD 모형의 적용 Application of STAD Model

정영란,이혜원 한국과학교육학회 2003 한국과학교육학회지 Vol.23 No.1

문제 해결 능력의 신장은 과학 교육의 중요한 목표로 간주되어 왔고 현 사회의 교육이 담당해야할 중요한 과제이다. 그러나 오래 동안 과학 수업을 받은 후에도 학생들의 문제 해결 수준은 향상되지 않았고 이에 효과적인 교수방법으로 학생들의 능동적인 참여와 토론을 기반으로 긍정적 상호 의존성을 기르면서 문제 해결 능력의 향상을 가져올 수 있는 협동학습이 제안되었다. 그러나 고등학교 생물 분야에서는 타 과학 과목에 비해 협동학습을 적용한 충분한 연구가 수행되지 못하였다. 따라서 본 연구에서는 인문계 고등학교 자연계 생물Ⅱ의 'Ⅱ. 물질대사'단원에 대하여 협동학습을 실시한 수, 학업 성취도 및 과학 학습 태도에 대한 효과를 전통적 수업과 비교하여 분석하였다. 연구 대상은 서울시 소재 여자 고등학교 2학년 자연계 학생들 100명이며, 2개 학급 중 한 학급은 협동학습을 실시하고 나머지 한 학급은 전통적 수업을 하였다. 본 연구의 검사도구는 학업 성취도 검사지의 경우 단원의 내용 및 수업 목표를 근거로 객관식 24문항으로 구성되었고 과학 학습 태도 검사 도구는 김인희(1994) 연구에서 개발된 총 40개의 리커어트 척도 문항으로 구성되었다. 본 연구는 사전-사후 검사 통제 집단(pretest-posttest control group) 설계에 기초하여 협동학습의 모형 중 STAD모형을 적용하였고 5주 동안 총 13차시에 걸쳐 실시되었다. 협동학습은 학업성취도를 향상시키는데 전통적 수첩보다 더 효과적이지 않았다.(p> .05). 협동학습은 상위 및 중위 수준의 학생들에게 효과가 없었으나 하위수준의 학생들에게는 전통적 수업보다 더 효과적이었다(p< .05). 협동학습은 전통적 수업에 비해 학생들의 과학 학습 태도 변화에 있어서 더 효과적이었다(p< .05). 과학 학습 태도에서 4개의 하위 영역 중 '과학에 대한 태도', '과학의 사회적 의미', '과학 교과에 대한 태도'의 영역에서는 협동학습이 전통적 수업 보다 효과가 없었으나(p> .05) '과학 교과에 대한 태도' 영역에서는 협동학습이 효과적이었다(p <.05). 협동학습은 상위 및 중위 수준의 학생들의 과학 학습 태도를 변화시키는데 효과가 없었으나 하위 수준의 학생들에는 효과적이었다(p< .05). Problem solving ability, having been thought as one of the most important goals of science educations is also a primary task for the current education. Indeed, the students' problem solving ability has shown almost no actual progress, despite our long accumulated science education. Under this circumstances, cooperative learning, a way to grow students' positive inter-dependence and problem solving ability in the basis of their active participation and discussion, was proposed as an effective teaching method. But, results have not consistently shown the advantage of cooperative learning over traditional learning for promoting academic achievement in science. Studies have consistently shown greater effectiveness on affective aspects. But, relatively few have focused on biology in Korea. The purpose of this study was to examine the effects of cooperative learning on the achievement and attitude consisted of 50 11th-grade female students in experimental group(cooperative learning-Student Team Achievement Division Model) and 50 students in control group(traditional learning). Students in both groups received identical content instruction on the unit Ⅱ. Mehtabolism'. These groups were treated for 13 hours during 5 weeks. Achievement data were collected using a 24-item multiple-choice test(content validity= .85). Science attitude was measured by and instrument which adapted by Kim In Hee(1994). The instrument(Cronbach α= .89) included 40 items in four subscales: attitude toward science, social meaning of science, attitude toward science class, and scientific attitude. An analysis of covariance(ANCOVA) was used as the data analysis procedure. For the achievement data, no significant difference exists between the cooperative and traditional groups (p> .05). But, cooperative learning was effective in low-ability students(p< .05). For the science learning attitude data, cooperative learning was more effective than the traditional one(p< .05). Students in the cooperative group achieved better than those in traditional one especially in the subscale of attitude toward science class. There was no meaningful difference of the two methods in both high and average ability students, while cooperative learning was more effective than the traditional one in low ability students(p< .05).

This study aims to investigate students' positions and values applied during decision-making processes on socioscientific issues (SSI), and to describe the patterns of change that occur in the students' decision-making. Thirteen high school students participated in the SSI program and the discussion topics of the SSI program were as follows: cloning, animal experimentation, MERS Corona Virus, global warming. We collected qualitative data which consisted of a pre and post interview of each student, the SSI group discussion, and worksheets that students responded before and after the SSI group discussion. As a result, the data showed that students tended to make decisions by applying 7 values; personal values, economic values, scientific values, rights and obligations, social values, ethical values, and medical values. The SSI instruction caused changes in the students‘ decision-making patterns which were categorized into 4 different types: (a) students who displayed consistent values and maintained the same position, (b) students who kept the same position but showed more diverse values and perspectives, (c) students who showed more diverse values and perspectives, and changed their position, and (d) students who showed more diverse values and perspectives, and took the opposite position. The students who changed their position tended to consider the reasons of the contrary position and took into account a variety of perspectives. Therefore, to improve students' decision-making skills, the SSI discussion program should be developed and utilized more widely. 본 연구에서는 과학기술관련 사회쟁점(Socioscientific Issue, 이하 SSI)에 대한 고등학생들의 의사결정에 영향을 미치는 다양한 가치를 분석하고, 수업 후에 학생들의 가치 판단에 따라 의사결정이 변화하는 유형을 살펴보고자 하였다. 이를 위 하여 인문계 남녀 공학 고등학교 2학년 13명을 대상으로 네 가지 SSI 주제(생물복제, 동물실험, 메르스 바이러스, 지구온난화)에 대한 토론 수업을 진행하였다. 수업 전과 후에 학생들이 작성한 의사결정에 대한 글쓰기 활동지, 개별 면담, 모둠별 토론 영상 자료를 수집하여 학생들의 의사결정 과정을 분석하였다. 본 연구의 결과, 학생들은 개인적 가치, 경제적 가치, 과학적 가치, 권리의무적 가치, 사회적 가치, 윤리적 가치, 의학적 가치를 적용하여 SSI에 대한 의사결정을 하였다. 그리고 수업 후에 학생들의 의사결정이 변화하는 유형은 일관된 가치를 적용하는 경우와 다양한 가치를 적용하는 경우로 나타났다. 학생들이 일관된 가치를 적용하는 경우에는 일관된 입장을 고수하는 것으로 나타났다. 그리고 다양한 가치를 적용하는 경우에는 일관된 입장을 고수하는 경우, 입장이 약화되거나 강화된 경우, 입장이 변경된 경우로 범주화할 수 있었다. 이때 입장의 변화를 보인 학생들은 토론 후에 자신과 반대 입장의 근거를 이해하거나 SSI에 내재된 다양한 관점을 고려하였다. 이러한 결과는 학생들이 토론을 통하여 자신과 반대인 입장을 공감하거나 다양한 관점을 수용함으로써 기존의 입장을 고수하거나 바꾸는 형태로 의사결정의 유형이 나타난 것으로 보인다. 따라서 정답이 없고 가치 판단이 요구되는 SSI에 대한 학생들의 의사결정능력을 향상시키기 위하여 학교 현장에서 활용 가능한 SSI 수업을 가치 교육의 측면에서 연구하고, 효과적인 수업 전략에 대한 개발이 이루어져야 한다.

지익성,김영희,신석철,왕성근,신윤오,이선우,김정란 충남대학교 의학연구소 2001 충남의대잡지 Vol.28 No.2

In order to assess the efficacy and safety of clozapine, 50 in-patients with treatment-resistanat schizophrenia were evaluated using PANSS(Positive and Negative Symptome Scale for Schizophrenia), CGI(Clinical Global Impression), AMS(Abnormal Involuntary Movement Scale), Adverse Event-Somatic Symptoms, Neurological Rating Scale for EPS before and during treatment. Mean daily dosage of clozapine was 344.15±123.43mg at 12th week. A clinically significant improvement in positive, negative, and general psychopathology was noted as early as week 2 through 12 week. The tolerability of clozapine was generally found to be good. Drowsiness/sleepiness, Hypersalivation, and Constipation were the most common side effects. There was no neutropenia, and 3 patients suffered from seizures. These results suggest that clozapine is worth considering for the treatment-resistant patients
