In order to clarify the effect of the unilateral pneumonectomy on the compensatory growth of the residual lung, liver and kidney, and serum electrophoresis pattern, right lung pneumonectomy was performed on rabbits under general anesthesia with pentobarbital sodium. On the fifth day after the surgery, the weight of the residual lung, liver and bilateral kidneys was measured and organ weight-body weight ratio was calculated. And in an attempt to know whether the cells in the liver and the kidney were proliferated by unilateral pneumonectomy, DNA content was determined. The quantity(g/100 ml) of serum protein was determined also and serum electrophoresis was performed on cellulose acetate membrane. The results obtained are summarized as following. The weight of the residual lung and lung weight-body weight ratio was significantly increased respectively. The weight of the liver and organ weight-body weight ratio were not changed but the DNA content of the liver and kidney tissue increased significantly, illustrating that unilateral pneumonectomy caused cellular hyperplasia in the liver and in the kidney as well as in the residual lung. The quantity(g/100 ml) of serum protein was significantly increased and in the analysis of the electrophoregram, there was significant difference between the normal and pneumonectomy group. Taken together, these results indicate that unilateral pneumonectomy caused the compensatory hyperplasia of the liver, the kidney and the residual lung as well as the change of electro-phoretic pattern. And it also suggests that a humoral factor, which proliferates the cells in the residual lung, the liver and the kidney, existed in the pneumonectomized rabbits.

벼 품종에 대한 가해능력을 달리하는 벼멸구 생태형의 저항성품종에서의 우화율 유전양상을 분석하고자 실내에서 저항성 품종(Mudgo, ASD 7)을 식이로 이대사육해 인위적으로 유발시킨 유발생태형 2 및 3과 기존생태형 1 사이의 상호 정역교배를 실시하여 $P_1,\;P_2,\;F_l\; F_2,\;BC_1$ 및 $BC_2$의 각세대 $1\~2$령 약충을 공시품종인 Mudgo, ASD 7 $1\~2$엽기 유묘에 접종하여 그 우화율을 조사하였다. 우화율에 대한 유전분석 결과, Mudgo에서의 생태형 2와 생태형 1사이의 조합에서는 생태형 2가 불완전 우성의 단일유전자 ASD 7에서의 생태형 3과 생태형 1 사이의 조합에서는 생태형 3이 불완전열성의 단일 유전자에 의해 우화율이 지배되며, 생태형 2와 생태형 3의 대립관계는 불명확하였다. To analyze the inheritance of emergence rate of brown plant hopper (Nilaparvata lugens) biotypes, six crosses among biotype 1, biotype 2 induced by rearing on Mudgo and biotype 3 these on ASD 7, were made. Each generation $(P_1,\;P_2,\;F_l\; F_2,\;BC_1,\;BC_2)$ of each cross was fed on the rice seedlings of Mudgo and ASD 7 varieties. The emergence rate of biotpe 2 on Mudgo was controlled by the one incomplete dominant gene in $biotype\;l{\times}biotype$ 2 coross, however, that of biotype 3 on ASD 7 was controlled by one incomplete recessive gene in $biotype\;l{\times}biotype$ 3 cross. The genes involved in biotype 2 and biotype 3 were not identical, however, their allelic relations are not clear.

Betamethasone이 일측폐장절제 가토폐장의 압력-용적곡선에 미치는 영향

이영만,이석강,Lee, Young-Man,Lee, Suck-Kang 대한생리학회 1983 대한생리학회지 Vol.17 No.1

steroid가 폐절제에 의한 대상성증식기의 폐장의 압력-용적곡선에 어떤 영양을 미칠 것인가를 알아보기 위해 실시한 본 실험의 결과를 요약하면 폐절제군은 대조군에 비해 폐용압률이 증가하였고 폐절제후 반대측폐장의 무게는 대조군에 비해 폐절제군이 유의하게 증가하였고 폐절제후 betamethasone을 투여한 군에 있어서는 대조군에 비해서는 증가하였으나 폐절제군보다는 적게 증가하였다. 또한 이러한 결과들은 betamethasone에 의해 폐포표면활성물질의 분비가 증가하였거나 혹은 betamethasone이 폐장실질의 결합조직의 단백대사에 영향을 미쳐 elastic recoil force가 감소하여 생긴 결과라고 생각된다. In order to clarify the effect of steroid on the pulmonary pressure-volume curve in the pneumonectomized rabbit, the right side pneumonectomy was performed under general anesthesia with pentobarbital sodium and the remaining lung was excised on the fifth day after surgery. The intrapulmonic pressure in the excised left lung was measured at 20, 25, and 30 ml lung volume during inflation and deflation period. In the steroid treated group, the intrapulmonic pressure at 20, 25, and 30 ml lung volume during inflation was significantly decreased compared with intrapulmonic pressure of the control group. But in the pneumonectomy group the decreasing tendency of the pressure was observed. During deflation, the intrapulmonic pressure at 25 ml and 20 ml was not significantly different from the control group in pneumonectomy and steroid treated pneumonectomy group. And the lung weight was measured in each experimental group and also the lung weightbody weight ratio(L/B) was calculated. The lung weight was significantly increased in both pneumonectomy and steroid treated pneumonectomy group. Calculated L/B was increased significantly in both group. Above results suggest that steroid increases the secretion of pulmonary surfactant or affects the catabolic effect on protein metabolism of connective tissue in lung parenchyma.

치매노인 부양가족의 스트레스에 관한 현상학적 연구

이영만,신동열,Lee, Young-man,Shin, Dong-yeol 산업진흥원 2020 산업진흥연구 Vol.5 No.2

WIn Korea, the rapid rise of elderly population and dementia prevalence resulting from the unprecedently rapid aging in the world is being emerged as a serious social issue. Caring the elderly with dementia is a different way from a general life and is a world which new cultural existential relationships are interlaced from the relationship viewpoint. From this aspect, the psychological matter of family caring a demented elderly needs to be studied for existential understanding in depth and fundamentally. This study focused on in-depth understanding and description of the stress phenomena experienced by family caregivers with a demented elderly based on Giorgi's method among phenomenological research methods and using existential group counseling techniques. Total 8 sessions of existential group counseling were conducted. This study drew out the outcomes(emotional stress, psychosocial stress, time-dependent stress) of participants' self-awareness experiences by applying 4 steps of Giorgi's phenomenological research methodology based on the Existential Philosophy to participant's intensive statements about stress of family caring a demented elderly drawn out of the existential group counselling sessions. It is hoped that understanding the pain of the supporters who cannot express their own pains through the research results and their self-help group counseling activities will become active, contributing to the health of our society which is about to enter post-aged society. 우리나라는 세계적으로 유례없이 빠른 노령화로 노년층의 인구와 치매유병률의 급격한 상승은 심각한 사회적 문제로 대두되고 있다. 치매노인의 부양은 보편적 삶과는 다른 방식이며 관계적 측면에서 새로운 문화적 실존 관계가 얽힌 세계이다. 이러한 측면에서 치매노인 부양가족의 심리적 문제는 단순한 기술적 문제를 떠나 심층적이고 본질적인 실존의 이해를 위해 연구할 필요성이 있다. 본 연구는 현상학적 연구방법 중 지오르기(Amedeo Giorgi)의 방법을 기반으로 치매노인 부양가족이 경험한 스트레스 현상을 실존주의 집단상담 기법을 활용하여 심층적으로 이해하고 기술하는 데 그 의의를 두었으며 집단상담은 총 8회기로 진행되었다. 실존주의 집단상담 과정을 통한 치매노인 부양가족의 스트레스에 대한 심층적 진술을 실존철학 기반의 지오르기 연구방법 4단계를 적용하여, 실존적 자기 인식 경험의 결과로서 정서적 스트레스, 심리 사회적 스트레스, 시간 의존적 스트레스 경험 현상을 도출하였다. 연구 결과를 통해 탐색된 자신의 아픔을 스스로 표현하지 못하는 치매노인 부양자 고통을 이해하고 치매노인 부양가족들은 자조적 집단상담 활동을 활성화하여 초고령화 사회 진입을 앞둔 우리 사회가 보다 건강해지는 데 기여할 수 있기를 기대한다.

이영만(Young Man Lee),최자형(Ja Hyung Choi),오세천(Sea Cheon Oh) 한국열환경공학회 2019 열환경공학 Vol.14 No.1

Recently, combustible waste has increased significantly as the industry developed, and most of these wastes are treated by thermochemical treatment methods. Among the various thermochemical methods, the most typical method is an incineration technology utilizing a combustion reaction, However, incineration technology has been fundamentally applied for the purpose of safe treatment rather than energy recovery. So, gasification research has been studied to improve the efficiency of energy recovery. The technology of waste gasification is basically based on coal gasification technology. Therefore, in this study, a thermochemical equilibrium modeling for waste gasification reactions has been studied by using the previous study on the characteristics of the coal gasification. And in order to verify the feasibility of the thermochemical reaction equilibrium model applied in this study, a comparisons with the field results were also performed.

초등학생의 성공지능 유형과 자기조절능력 및 학습몰입의 관계

이영만 ( Young Man Lee ) 한국초등교육학회 2009 초등교육연구 Vol.22 No.2

이 연구에서는 초등학생들의 성공지능 유형과 자기조절능력 및 학습몰입과의 관계를 분석했다. 세 가지 검사 도구에 대한 신뢰도를 검토하여 수정한 후 초등학교 4~6학년 350명을 대상을 검사를 실시한 후 응답의 성실성을 검토하여 287명을 최종분석 대상으로 하였다. 먼저 세 가지 검사별로 학년별 차이와 성차를 검토하였다. 다음으로 성공지능의 세 가지 하위지능별로 강점을 확인한 결과 세 가지 지능 모두 강한 균형성취자(A-C-P), 분석적 창조자(A-C), 분석적 실천가(A-P), 그리고 분석가(A)의 4가지 유형이 확인되었다. 세 가지 지능이 모두 강한 균형성취자가 자기조절능력 및 학습몰입 수준 모두 통계적으로 높은 점수를 보였으며, 강점 지능이 둘 이상인 학습자가 모두 높은 점수를 얻었다. 이상의 결과를 토대로 성공지능과 자기조절능력, 학습몰입 수준, 그리고 학업성취도 간의 관계에 대해 논의했으며, 연구 결과와 논의를 토대로 본 연구가 수업에 주는 시사점과 후속연구를 위한 방향을 제시했다. The purposes of this study were to classify successful intelligence styles, analyze the relationships between successful intelligence styles and self-regulation ability and learning flow. The subject were 287 4th~6th grade elementary school children. Three kinds of instruments were used to gather data for successful intelligence, self-regulation ability and learning flow after checking the reliabilities. According to the results of data analysis, first of all, I found four styles of successful intelligence; Analyzer(A), Analytic Creator(A-C), Analytic Practitioner(A-P), and Consumate Balance(A-C-P). Students who were classified as A-C-P style showed significant higher scores on cognitive and motivational factors of self-regulation ability and learning flow than other three successful intelligence styles. Hence, students who has the A-C-P style had more higher self-regulative skills, and could control their learning processes more effectively and got higher level of learning flow. These two variables, self-regulation ability and learning flow, could be considered as mediating variable between successful intelligence and academic achievements. Program developers who want to focus on successful intelligence and academic achievement can use these results as basic data for their program. Finally, I discussed the above results with the preceding studies and theories, and suggested some implications of this study and future directions of studies. As a final remarks, grouping students using their intellectual ability scores could be blended other important variables, like a political or socio-economic characteristics of students, it is worth to comment that grouping and classifying students should be implemented very carefully.

The purpose of this study were to organize and understand the research trends about the teachers` psychological burnout. For this purpose, 111 degree thesis and journal articles were selected through KERIS (http://www.riss.kr) & National Assembly Library(http://dl.nanet.go.kr). First, as a basic analysis, these studies were counted by the pressed years, the kinds and statistical characteristics of instruments for measuring teachers` level of psychological burnout. Second, the research trends were organized and interpreted by teachers` demographical variables and two kinds of research periods, that is, 1985∼2001 and 2002∼2012. The criteria of organizing and classifying the research trends were the job stress, organizational characteristics of school, teachers` individual characteristics, the mediating or buffering variables, the effects of psychological burnout, and the preventing/intervening methods against the psychological burnout. Finally, the analyzed results were described and discussed according to these criteria, then the implications for the further research were presented.
