金成學 한국교육학회 1996 敎育學硏究 Vol.34 No.5

이 연구는 일제시대 在外유학생들의 교육연구활동을 분석하여, 그들이 일제시대에 어떤 서구교육학(혹은 교육사상)을 도입했는지를 규명하고자 했다. 그리고 그것이 한국교육학연구 사에서 갖는 의미를 파악해 내려고 하였다. 연구의 결론은 다음과 같다. 첫째, 1920년대에 在日本朝鮮敎育硏究會와 ≪敎育硏究≫의 출현, 그리고 일본과 미국유학을 통한 교육학연구자의 계속적인 충원은 1920년대에 이르러 단순 번역시대를 지나 교육학연구의 시대로 접어들기 시작했음을 의미했다. 그러나 이는 본격적인 교육학연구의 시대로 나아가기 위한 과도기로서의 성격을 내포하고 있었다. 1945년 이후의 교육학연구의 흐름은 이런 교육학연구의 학문적 전통을 계승한 것으로 보아야 한다. 둘째, 일제시대에 일본유학생과 미국유학생이 서로 다른 서구교육사상을 수용하고 있었다는 점은 이후 미군정기 교육주도세력들간에 전개된 갈등에 한 가지 교육내적 원인으로 작용했다는 해석도 가능하다.

김성학,김경준,Kim, Sung-Hak,Kim, Kyung-Jun 대한한방안이비인후피부과학회 2006 한방안이비인후피부과학회지 Vol.19 No.3

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.

군대식 학교규율의 등장과정과 사회적 기능, 1880~1910

김성학 한국교육사회학회 2006 교육사회학연구 Vol.16 No.4

이 연구는 병식체조를 중심으로 군대식 학교규율의 등장과 확산 과정을 분석하고, 그 사회적 기능을 규명하고자 하였다. 대상 시기는 1880년대에서 1910년까지였다. 연구방법으로는 역사적 방법을 활용하였다. 연구결과는 다음과 같았다. 첫째로 원산학사에서 개화기 최초로 가르치기 시 작한 군사훈련은 1890년대 초반에 일부 선교계 학교에서 국내외 군인들이 체조시간에 본격적으 로 가르쳤다. 둘째로, 병식체조는 일본인 고문들의 영향과 당시 조선인들의 요구를 적극 수용하 려는 조선인 관료들의 노력에 의해 1895년 교과과정에 처음 등장했다. 이후 1906년에 일본인의 관여로 관공립 보통학교 교과과정에서 병식체조가 사라졌다. 1909년 체조 교과과정 변동은 병식 체조의 완전 소멸과 스웨덴체조를 기조로 한 ‘학교체조’의 등장을 특징으로 했다. 셋째로, 정부는 1906년 이전에 관립 외국어학교에 국내외 군인을 체조교관으로 파견해 병식체조를 매우 적극적 으로 실시하였다. 넷째로, 1906년 이후 병식체조의 전개 과정은 관공립 학교에서의 배제와 사립 학교에서의 몰입의 과정이었다. 거의 모든 사립학교에 병식체조가 확산된 것은 조선인의 요구에 서 비롯되었다. 다섯째로, 병식체조는 군주를 중심으로 사회를 통합시키고 국권을 회복하는 데 필요한 용감한 전사를 양성하는 기능을 수행하였다. 이러한 병식체조의 전개과정을 학교규율이라 는 측면에서 보면, 학교 안에서 군대식 규율이 확고한 정당성을 획득해 가는 과정이었다. 1910년 이전 군대식 학교규율은 당시의 시대적?사회적 산물이었다. 현재 잔존하는 군대식 학교규율은 21세기 시대 요구에 적절한 것인가에 대한 검토가 필요하다. This research was to analyze the appearance and expansion of military disciplines in schools through the case of military gymnastics and to find out its social functions from 1880's to 1910. The results were as follows; First, military drill, which was carried out in Wonsanhaksa for the first time in modern times, was taught in earnest in early 1890's by foreign and domestic soldiers in gymnastic classes in some Christian schools. Second, military gymnastics first appeared in the curriculum in 1895, owing to Japanese consultants' influence and the endeavor of Korean officials who wanted to meet the demands of Koreans then. Military gymnastics disappeared from the elementary school curriculum by Japanese intervention in 1906. In 1909, the change in gymnastics curriculum was characterized by the disappearance of military gymnastics and appearance of school gymnastics based on the Swedish gymnastics. Third, Korean government sent foreign and domestic soldiers as physical education instructors to foreign schools before 1906 and implemented military gymnastics in full force. Fourth, military gymnastics was eliminated from national and public schools and spread throughout private schools after 1906. It was in order to meet the demands of Koreans that military gymnastics was carried out in almost all private schools. Fifth, military gymnastics played a role in unifying Korean society under the king and raising brave fighters to restore national rights. To sum up in terms of school discipline, the historical process of military gymnastics was the process by which military discipline achieved a firm legitimacy in school. Before 1910, military discipline in schools was a product of the time and society. As for the military discipline that still remains in the schools of the 21th century, we need to examine whether it is suitable for the modern times.

김성학 梨花女子大學校 醫科大學 醫科學硏究所 1988 EMJ (Ewha medical journal) Vol.11 No.4

The object of this investigation was to study the effects of Naloxone on histopathological changes in cats subjected thoracic cord contusion. Twenty cats were divided 4 groups : The first group was sham control(3 Cats). The second group was the impact group that was induced by T_9 cord injury without treatment(6 Cats). The third group was the saline group that was induced by T_9 cord injury and treatment with Saline(6 Cats). The fourth group was the Naloxone group that was induced by T_9 cord injury and treatment with Naloxone(6 Cats). The histopathological evaluation of the injured spinal cords in Naloxone-treated Cats had less tissue damage than would be observed in time-matched standards. The histopathology in Saline-treated group had slightly better than typical of what we would expect in impact group.

김성학,Kim, Seong-Hak 한국정보처리학회 1994 정보처리논문지 Vol.1 No.3

자동제어는 그 대상이 근사적 수식화가 가능한 선형시스템에 주로 적용되고 있다. 제어대상에 대한 수학적 모델링이 명확하게 결정되지 않는 경우에는 사람이 직접 제 어하는 수동제어를 하게 된다. 본 논문에서는 수영장과 같이 거의 전적으로 숙력가의 경험에 의존하고 있는 수동제어를 자동제어가 가능하게 FLC(Fuzzy Logic Controller) 를 구축하고, 여기서 사용되는 지식을 가장 최적의 상태로 유지하기 위해 genetic 알고리즘을 사용하여 전문가로부터 얻어온 지식을 개선한다. 또한 규칙부와 소속함수 는 동시에 수정되도록 알고리즘을 설계하여 수동제어보다 제어 성능이 향상됨을 보인 다. Automatic control has been for the most part applied to linear systems where ti can be approximately formalized. In case that it is not definitely established the mathematical modelling to control objects, it requires manual control strategies which put under the human rule. In this paper, it constructs an FLC (Fuzzy Logic Controller) in order to turn a hand control into an automatic control in the domain of swimming pool that has been almost absolutely dependant on a skilled worker's experience. Genetic algorithms upgrade the knowledge which is acquired from human expert, using by FLC, so as to maintain knowledge in the very optimal way. It also designs an algorithm that modifies the rule base and the membership function at the same time, and ultimately will show that it can get better result than human controllers.

외상후 지연성 뇌실질내출혈에 대한 임상적 연구

김성학 梨花女子大學校 醫科大學 醫科學硏究所 1985 EMJ (Ewha medical journal) Vol.8 No.4

Twelve cases of delayed traumatic intracerebral hematoma(DTICH) were found retrospectively among 826 patients with closed head injuries admitted to the Department of Neurosurgery, College of Medicine, Ewhe Womans University in a 2-year period. All cases had severe head injuries sustained with the head in motion. The interval from cranial injury to diagnosis of DTICH by computerized tomography(CT) varied from 15 hours to 11 days. The diagnosis was made on repeat CT scans obtained because of the development of focal findings, lack of improvement and/ or general neurological deterioration. One patient had initially negative CT scans. Six patients demonstrated only extracerebral hematoma on initial CT scans. Two patients showed acute intracerebral hematoma on the initial scan followed by new hematomas on repeat study. Ten patients were treated surgically, and eight had fair & good results. The cases presented are discussed in the light of pertinent literature.
