경성사범학교 학생 훈육의 성격

김성학 경희대학교 부설 교육문제연구소 1999 論文集 - 경희대학교 교육문제연구소 Vol.15 No.-

이 연구는 지금까지 학교 현장에서 실천되어 온 학생 훈육의 역사적 맥락을 이해하기 위해 일제시기 경성사범학교에서 이루어진 훈육의 내용과 형식의 특성을 파악하고자 하였다. 1920년대와 1930년대의 훈육의 변화 양상에도 주목하였다. 연구결과는 첫째로, 일반 중등학교에 비해 상대적 혹은 절대적으로 더 강조되고 있던 수신과와 체조과를 통해 순종과 忠의 윤리, 및 武士정신과 집단정신의 내면화가 시도되고 있었다. 둘째로, 거의 일상화된 의식과 행사를 통해 천황제와 군국주의의 합리화를 위한 천황숭배 의식, 집단정신, 군인정신을 주입하려고 하였다. 이 과정에서 선서의 강요, 노래 및 운동회의 의식과의 결합, 위계적·고정적 순서, 경례의 반복 등이 나타나고 있었다. 셋째로, 적어도 1920년대 중반부터 황국신민화·군국주의 교육을 실시하고 있었다. 1930년대에 그것이 더욱 강화되고 있었다. 넷째로, 경성사범학교의 학생 훈육은 정교한 행동통제, 위계적 학생집단의 편성, 기숙사 제도라는 형식에 의해 뒷받침되고 있었다. 학생들의 저항 행위도 나타났지 만, 그것을 일반화하기는 힘들었다. 결국 경성사범학교의 학생 훈육은 순종하는 집단정신과 육체의 생산, 즉 천황의 신하 만들기와 군인 만들기 과정이었다. 이러한 학생 훈육은 1930년대 후반 이후 더욱 강화되어 갔을 것이다. 경성사범학교의 지도적 위치로 인해 그 훈육의 내용과 형식은 전 관·공립 학교로 전파되어 보편적 관행으로 굳어져 오늘날까지 잔존하게 되었을 것으로 이해할 수 있다. 일제시기의 훈육은 일본인들이 식민지 시대에 필요한 인간의 양성을 위해 학교현장에 도입한 것이었다. 탈근대의 시대에 접어들고 있는 지금, 지난 날의 훈육 내용과 형식을 정밀하게 재검토하고 시대에 걸맞는 것으로 재조정하는 작업이 요청되고 있다. In this study, it was a primary concern to analyze the characteristics of the education for specific disciplines and personalities at Kyung-Seong normal school. The results of it were as follows. 1) By the subjects of moral education(Su-Sin) and gymnastics which were more emphasized than at the general secondary schools, it was attempted to internalize allegiance and collective spirit. 2) Students were demanded to cultivate the cult mind of the Japanese Emperor, collective spirit and soldier's mind through the ceremonies and events which were held frequently. 3) At least in 1920s the liege man-making and militaristic education was begun at the school, In 1930s it was more strengthened. 4) The education for specific disciplines and personalities at the normal school was supported by the means of the elaborated behavior control, the hierarchy of students groups, and the dormitory system. All the these facts show that the education at the normal school was the liege man-making and military man-making education. The educational contents and means for specific disciplines and personalities which were practiced in Japanese colonial period have remained at Korean schools till now. It is the time that we reexamine it and readjust it to postmodern times.

Cerebral cysticercosis, is unfortunately, a frequent disease in Korea. Cysticercosis in man is exclusively due to the development of Taenia solium larvae, called Cysticercus cellulosae, which is a frequent parasite in the pig. The clinical symptoms which are varied and similar to those of any other tumor of the brain, are depent on the location, number of parasite, intensity of infestation and susceptibility of the host. The headache, vertigo, nausea and vomiting, appearing periodically, and chiefly after a rapid change in the position of the head, were indicative of a cysticercus lying free in the fourth ventricle. We have recently experienced a case of cerebral cysticercosis which involved the 4th ventricle. A forty-year-old man was admitted to the Department of Neurosurgery, College of Medicine, Korea University in June, 1978 bacause of severe headache, repeated vomiting and diplopia which progressed gradually for two months previous to admission. On admission, there were no specific legalizing and lateralizing neurological abnormalities except for signs of mild cerebellar dysfunction and signs of increased intracranial pressure accompanying with bilateral optic papilledema. Conray ventriculogram disclosed the dilation of proximal portion of the 4th ventricle and smoothly rounded central filling defect of the 4th ventricle. Brain C-T Scan demonstrated the marked dilation of 4th ventricle in round shape without evidence of midline shift or compression. This enlarged 4th ventricle with water density was shown no evidence of the contrast inhancement. Suboccipital craniectomy was performed arid a cystic mass was removed from the fourth ventricle. Pathological diagnosis of the specimen was cysticercosis. Following surgery, the patient's symptoms cleared up and neurological deficits and papilledema improved gradually.

Objective : Angiogenesis is an essential process for metastasis of solid tumors and Psoriasis. Lots of Researches for anti-angiogenic effect to angiogenic factors have been carried out in the world. So this experiment was carried out for whether Lacca Sinica Exsiccata(LSE) extracts have an anti-angiogenic effect for angiogenic factors. Methods: To investigate the roles of the LSE extracts, we performed MIS assay, western blots using HaCaT cells and HepG2 cells. And then, HaCaT cells were treated with 10, 50, 100, 250, $500{\mu}g/ml$ LSE extracts. After 4hrs, HaCaT cells were theated with IGF-II protein for 1hr. HepG2 cells were treated with 1, 10, 25, 50, 100, 200 ${\mu}g/ml$ LSE extracts. After 4hrs, HepG2 cells were theated with $CoCl_2$ for 24hrs Results: 1. In $50{\mu}g/ml$ and $100{\mu}g/ml$ density we confirmed the inhibition effect of LSE extracts to $HIF-1{\alpha}$ activation which was induced by IGF-II in HaCaT cells. 2. In $50{\mu}g/ml$ density we confirmed the inhibition effect of LSE extracts to $HIF-1{\alpha}$ activation which was induced by $CoCl_2$ in HepG2 cells. 3. In $25{\mu}g/ml$ density we confirmed the inhibition effect of LSE extracts to VEGF activation which was induced by $CoCl_2$ in HepG2 cells. Conclusion: The above-mentioned results proved that LSE extracts reduced $HIF-1{\alpha}$ protein level in the HaCaT cells and HepG2 cells. These results suggest that inhibition of HaCaT cell and HepG2 cell proliferation by LSE extracts contributes to the anti-angiogenic activities on the keratinocytes and hepatocellular carcinoma.

0bjective : The purpose of this study is to investigate e effects of preischemic hyperglycemia on e alterations of'adenosine triphosphate and lactate concentrations in e acutefocal ischernic brain of the cats. Methods : Acute focal cerebral ischemia in cats was induced by occlusion of the left middlecerebral artery through the postorbital technique. The experimental animals were divided into 3 goups : sham control, occlusion and recirculation groups. Each group was divided into 2 subgroups : normoglycemic and hyperglycemic groups. Results : The experimental results are obtained as fo11ows ; 1) In normoglycemic subgroups of occlusion and recirculation proups, amount of adenosinetriphosphate in ischmic brain decreased significantly to 3.0% and 13.0% of the sham control,respectively(p < 0.001). In hyperglycemic subgroups of occlusion and recirculation groups, amount of adenosine trisphosphate decreased a little more an at in normoglycemic subgroups, even so there wasno statistic significancy(p > 0.1). 2) In normoglycemic subgroups of occlusion and recirculation groups, amount of lactate inischemic brain increased signigicantly to 175.7% and 187.9% of the sham control, respectively(p< 0.001). In hyperglycemic subgroups of occlusion and recirculation groups, amount of lactate increased nore than that in normoglycemic subgroups with statistic significancy(0.001<p<0.01). Conclusion : These results suggest that hyperglycemia before ischemia serves to elevate glucose transport into brain tissue and thereby, to promote profound tissue acidosis throughanaerobic glycolysis caused by a failure of adenosine triphosphate stnthesis during e ischemicperiod.

식민지시기 페스탈로찌 수용과정 연구

김성학 경희대학교 부설 교육문제연구소 1998 論文集 - 경희대학교 교육문제연구소 Vol.14 No.1

본 연구는 식민지시기에 조선인들이 페스탈로찌를 수용해 온 전 과정과 그 사회적 맥락은 아직 파악되지 못하고 있다는 인식 아래, 첫째로 식민지시기에 페스탈로찌를 수용해 온 과정을 확인하고, 둘째로 수용한 페스탈로찌관과 교육사상을 분석해 내며, 셋째로 당시의 사회경제적 상황과 페스탈로찌 수용간의 관련성을 파악하고자 하였다. 1920년대부터 1930년대 초반 사이에 이루어진 페스탈로찌 수용의 주요 계기는 1920년대의 문화운동과 1927년의 페스탈로찌 서거 백주년 기념제였다. 주요 매개기관은 동아일보사와 연희전문학교였다. 수용자들은 대부분 교육학을 배운 인사들이었다. 수용자들은 페스탈로찌를 빈민아동 교육가, 혹은 사회개량가라고 거듭 강조하고 있었다. 그의 교육사상의 소개는 Natorp가 정리해 놓은 교육원리를 일본을 통해 간접 수용하는 수준이었다. 그리고 농민층의 급속한 하강 분해, 그에 따른 대다수 농민의 빈농화, 교육기회를 박탈당한 농촌 아동의 퇴적 등 당시의 사회경제적 상황은 페스탈로찌 수용을 촉진시킨 '구조적' 요인으로 작용하고 있었다. 그러나 실제로 수용을 실현시킨 것은 문제해결 지향성이 강했던 조선인들의 의도적 수용 노력 때문이었다. 이와 같은 노력의 효과는 미지수이지만, 이 때부터 페스탈로찌는 교사들에게 이상적인 스승상으로 자리 잡아가기 시작했던 것으로 보인다. The purpose of this study was to examine the process of introduction of Pestalozzi into Korea in the colonial period and the relation of it with the socio-economic condition in that times. Koreans continued to introduce Pestalozzi from 1920's to early 1930's in the colonial period. In that effort. many writings on Pestalozzi appeared in the part of the cultural movement of 1920's and with the centenary of his death in 1927. The major institutions of introduction were The Dong-A Ilbo and Yonsei college. The most of writers had learned the subject of education. They emphasized repeatedly Pestalozzi as the educator for poor children or social reformer. But they didn't advance over the level of the introduction of Pestalozzi's educational thoughts after his educational principles which were analyzed by Natorp who had been discussed in Japan. The socio-economic conditions from 1920's to early 1930's such as the rapid degradation of farming population to lower class, their poor life, and the deprivation of educational opportunity of them, were structural factor which promoted the introduction of Pestalozzi into Korea. In addition, Koreans' intentional efforts to solve the problems made it actually introduced into Korea. However, it was doubtful whether such efforts were successful. Although this was a fact, it seemed gradually that Pestalozzi began to be regarded as a ideal model for educational practice by Korean teachers.

교육학지식 형성 과정에 대한 분석과 모형의 탐색

김성학 서원대학교 교육연구소 2002 敎育發展 Vol.21 No.1

This research explored analytic model on the formative process of pedagogic knowledge in Korea of 1950's. Why this research focused on 1950's was that in that period new pedagogic paradigm could be shaped which was different from that of colonial period. And this research approached to the problem of knowledge formation by sociological method. For it, this research critically reviewed two theories related to knowledge formation: sociology of knowledge and theory of transnational knowledge transfer. The results were summarized as follows; Firstly, while sociology of knowledge examined various social conditions which affected knowledge formation, it used the concept of knowledge in a great many meanings and fell into epistemological arguments about relativism. Consequently, empirical researches were very rare. Above all, it didn't consider that knowledge was conditioned by social factors and it could have influence on the society at the same time. Secondly, the theory of transnational knowledge transfer showed us the influence of western states on the knowledge formation in peripheral state. Nevertheless it failed to recognize the specific social conditions in peripheral state and the positive role of educational groups in it. These results requested that two theories be integrated and new variables be added to explain the formative process of knowledge in Korea of 1950's. Analytic model on it should involve variables and relations among them as follows; External factors and internal factors were involved in the model. The former was the strong influence of the west, especially American academic communities by various means. The latter was the conditions in Korean education, society and system. The examples of the latter were educational substructure expanded rapidly, bureaucratism in society, furious ideological competition between south and north Korea in that times. Interacting and having selective affinity with specific pedagogic knowledge, these two factors condition its characteristics and form. At the same time they intervene in the formation, the growth and the activities of the domestic groups related with the formation of pedagogic knowledge. In turn, the domestic groups also serve to produce the pedagogic knowledge possessing specific characteristics. These pedagogic knowledges generate the effect of it, namely power. The power includes the force of social domination and micropower over personal behavior. Being accumulated with the lapse of time, the power has influence on internal factors, external factors and the domestic groups. This process is long-term. The effects of power become different by times. And the operation could be explicit or latent. In the future, empirical researches should be performed to identify more variables in the model and verify relations among them.

중국기업에서의 일-가족 갈등의 영향요인과 결과요인

김성학,정범구 충남대학교 경영경제연구소 2008 경영경제연구 Vol.30 No.2

최근에 일과 가족의 상호성에 대한 연구의 필요성과 관심이 증가하고 있으며 이러한 두 영역 간의 역할갈등이 일과 가족의 상호 연계성을 분석하는데 있어 핵심 개념이 되고 있다. 일-가족 갈등은 조직몰입, 직장생활만족, 이직의도 등의 조직효과성과 직원들의 가정생활에 부정적인 영향을 미치는 것으로 알려져 있다. 본 연구는 일-가족 갈등과 직무만족, 조직몰입과의 관계에 초점을 맞추고 일-가족 갈등에 영향을 미치는 영향요인인 개인특성, 가족특성, 조직문화특성과 일-가족 갈등이 영향을 미치는 결과요인인 직무만족과 조직몰입에 대하여 알아보고자 하였다. 연구결과 개인특성에 있어서 직원들의 외향성, 그리고 친화성이 강할수록 지각하는 일-가족 갈등이 낮아졌고, 가족특성 또한 일-가족 갈등에 영향을 미쳤으며, 조직문화특성에 있어서 직원들이 느끼는 집단문화, 개발문화, 합리문화가 강할수록, 위계문화가 약할수록 지각하는 일-가족 갈등이 낮아졌으며, 일-가족 갈등이 높을수록 직무만족과 조직몰입에 부정적인 영향을 미치는 것으로 나타났다. 이러한 결과들은 미국과 유럽 등 서방의 나라들에서 많이 이루어졌던 연구를 중국의 실정에 적용하여 선행연구에서 제시했던 연구결과가 문화적 차이가 있는 중국에서도 의의가 있음을 보여주었고, 중국의 기업경영에 있어서 시사점을 제공하여 직원들이 직장과 가정 사이에서 느끼는 갈등의 최소화를 위한 노력이 필요함을 시사하고 있으며, 중국의 기업들에서 기존의 조직문화로부터 더 적합한 문화를 발굴하고 창조하는 방향을 제시하고 있다.
