      • 상호작용 증진을 위한 웹 기반 발표학습 전략

        이재운,김성식,Lee, Jae-Un,Kim, Seong-Sik 한국컴퓨터산업학회 2007 컴퓨터産業敎育學會論文誌 Vol.8 No.4

        최근의 교육적 패러다임은 정보 통신의 발전에 따라 지식의 수동적인 전수자로서의 교육이 아닌, 실세계의 복잡하고 다양한 문제를 해결할 수 있는 능동적인 구성자로서의 교육을 요구하고 있다. 이러한 변화는 정보와 아이디어의 소유보다는 공유를 통해 다른 사람의 다양한 시각을 접할 수 있는 교육-환경을 요구한다. 이에 본 연구에서는 발표학습을 통한 상호작용 효과를 극대화하기 위해 발표의 일회성에 기인하는 단점, 발표자료의 재활용이 미흡한 점을 보완하며, 상호작용 활동의 연장, 발표활동에 참여하지 못하는 학습자에 대한 동기 부여를 통해 지속적인 상호작용이 가능하도록 웹 기반 형태의 발표학습 전략을 설계하였다. 이를 위해 동료학습자간 발표자료 제공자와 학습자로 구분하여 각각의 역할을 제시하고, 발표학습을 지원하기 위한 시스템 구성 전략을 단계별로 제시하였다. 본 연구에서 제안하는 발표학습 전략을 통해 동료학습자간의 지속적인 상호작용이 가능하며, 시 공간 제약없이 하교 후에도 가정에서 발표학습 활동이 계속 이루어져 상호작용을 통한 교육적 효과가 클 것으로 기대된다. Recording to development of info-communication, recent educational paradigm asks not for a passive transmitter but an active constructor who can solve the various complicated problems in real situations. Such a change asks for the educational setting which includes sharing ideas and information rather than possessing them by themselves. Learning through presentation has many problems which are few chances of presentation as well as reusing of presentation data. etc. This study suggested the strategy which are promoting interactions through presentation class and using practically. For this, role of the presentation data provider and learner was suggested, also strategies to implement of the presentation learning support system step by step. Through the strategy of this paper could maintain the active communicating relationship between the learners. Without the limitation of the time and space, the real time communication is made while looking at the presentation data of the other party, the teaming effect by the presentation teaming strategy is expected to be high.

        급성사혈이 저온견의 심폐동태에 미치는 영향

        이재운,Lee, Jae Woon 대한심장혈관흉부외과학회 1969 Journal of Chest Surgery (J Chest Surg) Vol.2 No.1

        This experiment was carried out to study the effect of rapid hemorrhage on cardiopulmonary hemodynamics of the cooled dogs. Hypothermia was induced by means of body surface cooling with ice water. Lowest esophageal temperatures ranged from 24 to 26 degree. Dogs were bled via the femoral artery into a reservoir in amount of the equivalent blood volume of 3% of body weight of the dogs. Some dogs were reinfused with the same amount of blood which they lost and others infused with 5% dextrose solution. Fourty adult mongrel dogs were divided into three groups: group I[15 dogs]; dogs were bled in normothermic state. Five dogs had no further treatment, but five dogs were reinfused with blood and five infused with 5% dextrose solution 30 minutes after bleeding. GroupII[10 dogs]; dogs were bled as group I after having been cooled. Five dogs were reinfused with blood as group I. Group III[15 dogs]; dogs were first bled and then cooled. Reinfusion procedures were the same as in group l Results were as follow: 1. The heart rate showed a slight decrease after bleeding in group I and then increased over the control level after 60 minutes. After reinfusion and infusion, the heart rate was also increased gradually and after three hours almost returned to the control level. In group II and groupIll, the heart rate decreased remarkably and after reinfusion showed a light increase but after infusion tended to decrease cotinually. 2. The stroke volume showed remarkable decrease after bleeding in group I., and recovered to control level after reinfusion and infusion,and then gradually decreased again. In group III, the stroke volume showed no remarkable change after hypothermia, and tended to decrease after reinfusion. In group III, the stroke volume decreased remarkably after bleeding and hypothermia,and clearly increased after reinfusion and infusion and then returned to control level. 3. Femoral mean pressure declined very rapidly and significantly right after bleeding and showed a remarkable prompt rise after reinfusion and infusion in group I [67% recovery]. On the other hand, it declined remarkably after hypothermia and bleeding and showed a slight rise after reinfusion and infusion in group II[46% recovery] and III [41% recovery]. 4. Venous pressure declined slightly after bleeding and tended to return to the control level after reinfusion and infusion,in group I. In group II, it did not change significantly during hypothermia but showed a slight decline after bleeding and returned toward control level after reinfusion. In group III, it declined slightly after bleeding and showed no significant change after hypothermia and rose over the control level after reinfusion and infusion. 5. Right ventricular systolic pressure decreased markedly after bleeding and then increased progressively after 30 minutes. It increased after reinfusion and infusion as well, approaching the control level in group I. In group II, it showed no significant change during hypothermia, but decreased remarkably after bleeding and then returned to near control level after reinfusion. In group III, it was decreased markedly after bleeding but did not change significantly during hypothermia and showed a slight increase after reinfusion. 6. The respiratory rate increased gradually after bleeding and decreased gradually after reinfusion but did not return to the control level, whereas it decreased near to the control level after infusion,and tended to increase in group I. In group II, it decreased significantly after hypothermia and bleeding but returned near to the control level after reinfusion. In group III, it showed a remarkable decrease after hypothermia and increased slightly after reinfusion and infusion but did not return

        이재운(Lee, Jaewoon),강경석(Kang, Kyungseok) 충북대학교 교육개발연구소 2016 한국교육논총 Vol.37 No.1

        본 연구의 목적은 교사의 교원성과급 등급이 조직몰입 및 조직시민행동에 미치는 영향을 분석하는 데 있다. 이를 위해 인천·경기 지역에 근무하는 초·중등 교사 762명을 대상으로 설문을 실시하였다. 연구의 결과를 요약하면 다음과 같다. 첫째, 교사의 조직몰입에 대한 인식 수준은 3.44, 조직시민행동에 대한 인식 수준은 3.99로 나타났다. 또한 배경 변인에서는 조직몰입 및 조직시민행동 모두 부장교사, 21년 이상 고경력교사, 한국교총 가입 교사의 인식 수준이 높게 나타났고, 조직몰입은 상대적으로 중등학교 교사와 남교사의 인식 수준이, 조직시민행동은 초등학교 교사의 인식 수준이 높게 나타났다. 둘째, 교원성과급 등급에 따른 조직몰입 및 조직시민행동의 하위변인 간 차이를 알아본 결과, 성과급의 등급과 하위변인들 사이에는 유의미한 차이가 있었고, S등급 교사의 조직 몰입과 조직시민행동의 수준이 가장 높고 다음은 A등급 교사, B등급 교사의 순이었다. 셋째, 교원성과급 등급이 조직몰입 및 조직시민행동에 미치는 영향을 알아본 결과, 교원성과급 등급은 조직몰입에 3.623-.218(A등급)-.392(B등급)만큼의 영향을 미치고, 조직시민행동에 4.132-.166(A등급)-.279(B등급)만큼의 영향을 미치는 것으로 나타났다. The purpose of this study is to examine the analysis on the effect of incentive gap of teacher’s merit-pay on organizational commitment and organizational citizenship behavior. The study verified the hypothetical path model and analyzed the effects of incentive gap of teacher’s merit-pay, organizational commitment and organizational citizenship behavior. The subjects of the study are 762 elementary and secondary school teachers. The results of the study are as follows: Firstly, it was found that there are significant correlations among incentive gap of teacher’s merit-pay, organizational commitment and organizational citizenship behavior. Secondly, incentive gap of teacher’s merit-pay affects organizational commitment and organizational citizenship behavior. Lastly, S grade teachers of teacher’s merit-pay are more organizational commitment and organizational citizenship behavior level were higher than A and B grade teacher. Therefore teacher’s merit-pay have positive impacts to the teachers.
