          제왕절개술 후 발생한 폐색전증 1예

          김길중,박철훈,노덕영,김용욱,박병준,신화정,김태응,정재근 대한산부인과학회 2003 Obstetrics & Gynecology Science Vol.46 No.3

          임신과 산욕기는 정맥혈전증과 폐색전증이 발생할 수 있는 위험한 시기이고, 이 질환들은 임산부 사망의 주요 원인으로 알려져 있으며, 치료하지 않는 급성 폐색전증의 사망율은 30%에 이른다. 본원에서는 제왕 절개술 후 발생한 폐색전증을 폐관류스캔과 정맥조영술을 통하여 진단하여 약물 치료를 한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. During the past 50 years, the maternal mortality ratio has decreased dramatically. The leading causes of maternal deaths were pulmonary embolism, the complications of the pregnancy-induced hypertension, hemorrhage, the complications of the ectopic pregnancy and infection. Pulmonary embolism is one of the most fetal maternal complications that abruptly happen and rapidly progress, and has been a major cause of maternal death recently. Early detection of pulmonary embolism is difficult, because there is not any specific clinical symptoms and signs. We have experienced a case of a fatal pulmonary embolism which was diagnosed by lung perfusion scan on postoperative 1 day after cesarean delivery and managed with heparin therapy. We report this case with a brief review of literatures.

          영어교육에서 텍스트의 의미 : 무엇을 왜 어떻게 가르칠 것인가

          김길중 서울대학교 2003 외국어교육연구 Vol.6 No.-

          This short essay is a slightly modified version of a presentation read at the annual Institute seminar held at SNU on the 5th of December to exchange views on the function of reading in foreign language education in Korea. It begins with the discussion of a need on the paπ of policy makers of English teaching to reassess and revise the dominantly pragmatic and instrumentalist philosophy particularly working in the pedagogy of reading in English. According to the revisionist review of the present writer, the guiding spirit of the 4-skill orientation has so far tended to overvalue the linguistic and communicative functions (or ’grammar’ as is termed here to contrast with the 'text’ that follows) at the cost of the human or readerly values carried by signifying textuality of the reading material. Language should and is fated to reflect and realize the lived experience of concrete and individualized people and society. English is a natural and cultural language that embraces a11 these cultural resourcefulness and expressiveness before it is a foreign language. Strategies of reading pedagogy ought to reflect this fundamental as well as human or value-oriented aspect of language despite the limited level of the language on the part of its leamers.

          Objectives : It has been demonstrated that nitric oxide (NO) serves as an inter- and intra-cellular messenger in the brain. NO has been implicated in the regulation of monoaminergic neurotransmission and the neuronal growth and synaptogenesis. Recently, NO has been suggested to be involved in the pathogenesis of depression. The aim of this study was to investigate the involvement of NO in the underlying mechanisms of biological vulnerability to depression. Methods : The author measured locomotor activities and postnatal behavioral changes in the forced swimming test (FST) in rats that were exposed prenatally to N^(ω)-nitro-L-argmine, a NO synthase (NOS) inhibitor. It was also investigated that paroxetine, a selective serotonin reuptake inhibitor, may affect the behavioral changes in the FST. Results : Locomotor activities were significantly diminished, and the immobility times in the FST were significantly Prolonged in the rats that were exposed prenatally to NOS inhibitor compared with controls. Pretreatment with paroxetme blocked the prolongation of the immobility times in the FST. Conclusion : The results indicate that postnatal behavioral changes due to prenatal exposure to NOS inhibitor in rats may suggest an animal model of endogenous depression, and that the glutamate-NMDA-NO pathway may be involved in the Pathophysiology of depression. It is also indicated that the action of NO may, in part, be affected by serotonergic mechanism. This implicates that the glutamate-NMDA-NO pathway may lead to a novel approach to the treatment of depression.

          한국인 대학생 영어 학습자의 필요 욕구 분석: 사례 연구

          김길중,신문수,양현권,김진완 서울대학교 1999 외국어교육연구 Vol.2 No.-

          For a new direction of college English programs, this study is designed to analyze Korean university EFL leamer needs. With this goal, this study discusses the results of questionnaires provided for 405 students in the College of Education, Seoul National University. The study also discusses a new direction of desirable English programs on the basis of the needs assessment.

          Mesodermal Formation and Patterning during Ascidian Embryogenesis

          김길중,니시다히로키 한국발생생물학회 2002 발생과 생식 Vol.6 No.2

          원시적인 척삭동물인 멍게에서 초기 배 세포운명은 모성 세포질인자와 유도적 상호작용에 의하여 결정된다. 매우 단순한 구조를 하고 있는 멍게 올챙이형 유생의 주요한 중배엽 조직으로 척삭, 근육 및 간충직이 존재한다. 근육 세포의 형성은 세포의 자율적인 과정으로, 초기 배의 후부 가장자리에 국재하는 모성 macho-1 mRNA에 의하여 근육 세포의 운명이 결정된다. 이에 반하여, 내배엽 전구세포의 유도작용은 척삭과 간충직 세포의 운명결정에 있어서 중요한 역할 In ascidians, a primitive chordate, maternal cytoplasmic factors and inductive interactions are involved in the specification of cell fates in early embryos. The larval structure of ascidians is relatively simple, and the major mesodermal tissues of the tadpole larva are notochord, muscle, and mesenchyme. Formation of muscle cells is a cell-autonomous process, and localized maternal macho-l mRNA specify muscle fate in the posterior marginal zone of the early embryo. In contrast, inductive influence from endoderm precursors plays important roles in the specification of notochord and mesenchyme fates. FGF-Ras-MAPK signaling is involved In the induction of both tissues. The difference in responsiveness of the posterior mesenchyme and anterior notochord precursors to FGF signaling is caused by the presence or absence of intrinsic factors that inherited from the posterior-vegetal egg cytoplasm, respectively. In these inductions, directed signal polarizes the induced cells and promotes asymmetric cell divisions to produce two daughter cells with distinct fates.

          순서정보에 의한 한글자획 온라인 인식을 위한 신경회로망에 관한 연구

          김길중,최석,이종혁,남기곤,윤태훈,김재창,박의열,이양성,Kim, Gil-Jung,Choi, Sug,Lee, Jong-Hyeok,Nam, Ki-Gon,Yoon, Tae-Hoon,Kim, Jae-Chang,Park, Ui-Yul,Lee, Yang-Sung 한국통신학회 1992 韓國通信學會論文誌 Vol.17 No.12

          본 연구에서는 한글자획을 온라인으로 인식하는 다층구조 신경회로망을 제안하였다. 입력되는 자획패턴에 대하여 전자펜의 현재 위치에 $4{\times}4$ 크기의 윈도우를 덧씌워 부분패턴으로 분리하고, 분리된 부분패턴내의 두드러진 특징을 추출한다. 이 특징들은 상층에서 취합되고, 취합된 자획특징은 추출된 특징의 통계적인 분포를 나타내며, 이 자획특징에 의해서 자획이 분류되어 인식된다. 본 연구에서는 처리할 정보량을 줄이고자 자획정보가 집중되어 있는 자획의 첫부분과 끝부분에서 자획특징을 추출하며 '?', '?'과 같은 모서리 특징을 갖는 자획은 첫부분과 끝부분에서 추출되는 자획특징간의 순서정보를 이용하였다. 제안 된 자획인식시스템은 구조가 단순하고, 처리속도의 개선이 기대된다. This paper proposes an on-line recognition system of Korean strokes using multi-layer neural network with tracing the stroke pattern. The system segments the stroke pattern into subpatterns, detects prominent stroke features in the subpatterns and integrates all the activation values of features in the related subpatterns. The activation values of the integrated stroke-specific features represent statistic characteristics of features and contributes for classifying the stroke pattern. Since the informations in Korean strokes are concentrated in the first and last parts of the strokes, the system extracts stroke-specific features in these parts attentatively and infers corner features using the sequential information of the extracted stroke-specific features in the first and last part of strokes the system is relatively simple in structure and rapid in on-line recognition of hand-written Korean strokes.
