경험적 사실과 허구적 진실

장영우(Chang Young Woo) 동악어문학회 2009 동악어문학 Vol.52 No.-

이 논문은 「퇴원」ㆍ「병신과 머저리」에 나타난 주요 모티프와 작중인물의 성격 분석을 통해 이청준 소설 미학의 특질을 규명하고자 씌어진다. 이청준 소설에는 ‘의사’와 ‘작가’가 자주 등장하는데, 이들은 각각 ‘사실’의 규명과 ‘진실’의 탐색이라는 상이한 역할을 담당한다. 그리고 애초에 개인의 성적 일탈 정도로 취급되었던 ‘전짓불’ 모티프는 차후에 ‘권력’과 ‘공포’의 문제로 사회화한다. 이청준은 경험적 사실의 재현보다 그 이면에 감추어진 개인의 심리적 진실에 더 많은 관심을 보이며, 그것을 ‘소설’의 형식을 통해 진술하는 방식을 선호한다. 그가 경험적 사실보다 허구적 진실의 추구에 더 큰 관심을 가지고 있다는 것은 그의 현실인식 매우 비관적이라는 사실을 뜻한다. 「퇴원」은 정상적인 의사소통을 통한 부자간의 화해를 주제로 한 작품이다. 그리고 「병신과 머저리」에서는 ‘누가 김일병을 죽였는가’의 문제가 중요한데, 그것은 지식인의 책임의식과 밀접한 관련을 맺기 때문이다. This study is writing to examine the specific character of the aesthetics on the Yi, Chungjoon's earlier novel(「Leaving Hospital」ㆍ「Byungsin & Merserri 병신과 머저리」), which get through to analysis of the main motif and the character of Yi's works. It is frequently found out 'the doctor' and 'the author' in his novels, whose unlike roles are to examine the realistic fact and to search for the truth. The 'Flash' motif is accepted sexual deviant behavior of the personal in the earlier, but alter to the problem of 'the authority' and 'the fear' to socialization later. Yi is more concerned about the psychological truth of the other side of reality than representing the fact of the personal experience, and he prefers to express in the form of novel. It does mean that he has very pessimistic cognition towards the real world. The theme of 「Leaving Hospital」 is a reconciliation which gets through a normal communication between the Father and the Son. And the issue of ‘Who killed Kim of private first class’ is very important at 「Byungsin & Merserri 병신과 머저리」, because it is related to close connection with the consciousness of responsibility of the intellectual class.

삼각함수 변환을 이용한 복소 계수 고차 방정식의 해법

장영우(Young Woo Chang) 한국정보과학회 1992 정보과학회논문지 Vol.19 No.4

복소 계수 고차 방정식의 해를 구하는 알고리즘에는 Jenkins-Traub Method, Newton-Raphson Method 및 그 변형 등이 있다. 가장 많이 쓰이는 Jenkins-Traub의 방법은 중근이 존재하는 경우를 고려하여 개발된 방법이나, 구해지는 근의 정밀도를 높이는 방법이 없고, 값의 차수가 서로 크게 차이나는 근들이 존재하는 고차식에서는 구해진 해들의 정확도가 떨어지는 단점이 있다. 이러한 문제들을 보완하고, 중근이 없는 경우에는 해의 요구 정밀도를 크게 높일 수 있고 또한 중근이 세 개 정도 이내의 어떤 복소 계수 고차 방정식도 정밀하게 풀어낼 수 있는, 근의 삼각함수 변환을 이용한 알고리즘을 개발하였다. 본 알고리즘은 고정확도를 요하는 공학 및 수학 분야에서의 실수와 복소 계수 고차 방정식의 분석에 응용될 수 있다. Among the rootfinding algorithms for complex coefficient polynomial equations, there are well known Jenkins-Traub method, Newton-Raphson method and its variations. Jenkins-Traub(J-T) method started considering multiple root cases and became one of the most favorite. But J-T method does not provide ways to improve the precision of the roots being computed. Also, it is verified that J-T method is not so strong when a given problem has mixture of roots that are of diverse orders. The method presented in this paper uses Trigonometric Transform(T-T) of the roots and appears to compensate the above deficiencies of J-T method. T-T method can be tried increasing the required accuracies of the given problem and the performance is excellent in non-multiple root cases. The algorithms are applicable to real/complex coefficient polynomial problems in precision-critical engineering and mathematical applications with three or less multiple roots.

When calculating the roots of a polynomial equation, inherent precision deficiency of the Newton-Raphson iteration method for multiple root cases often run into incorrect results. A simple and easy-to-implement algorithm for determining root multiplicity is presented and a sample problem is solved to show the iteration characteristics of multiple root computations.

초등학생의 토론 능력 신장을 위한 논증 전략 교수-학습 모형 연구

장영우(Chang Young-woo) 한국어문교육학회 2005 어문학교육 Vol.30 No.-

Linguistic abilities in communication of which individuals are able to be possessed in modern society are among most important ingredients to be in the mercy of success and failure of self-realization and life in society. Above all, the most important among them is, I think, discussion ability. Discussion is among dialogue styles which logically prove one's insistence and then are focused on the process to solve a problem. So ,we can say, the most important ingredient in good discussion is 'demonstration ability' which is enable us to prove their insistence logically. But, there isn't real and good discussion teaching because of the shortage of understanding for roles and concepts of demonstration and of development of teaching-learning method. So, this study is focused on developing teaching-learning model of demonstration strategy for developing discussion ability of elementary school students and I'd like to deal with three research problems, the following. First, to develop demonstration ability, after we should set up model of demonstration structure and formulate by stages, and concretely teach each ingredients of demonstration and the strategy concerned. Second, we should look for the model for suitable teaching-learning in the guidance of elementary school students, applying the strategy of demonstration which has been learned to discussion. Third, we should apply this method to class and analyze the result of this guidance. The model for teach the structure of demonstration to elementary school students was set up on the basis of 'demonstration structure of Toulmin' and 'The method of six stages in discussion' written by Kim Byung-won, and divided class as three stages for systematic guidance. The basic system of teaching-learning model for the strategic guidance of demonstration is followed. <The Basic System of Teaching-Learning Model for Guidance of Demonstration Strategy> <그림> The suggestion which we can get by means of this research is followed. First, students can figure out demonstration as the result of setting up the model for teachers to teach a demonstration strategy to elementary school students and teaching by stages. I could logically develop my insistence in real discussion by drawing the strategy which is essential in guidance and by teaching the form of thought with data. Second, I could develop discussion ability of students as teaching discussion systematically through making the model of teaching-learning for guidance of demonstration strategy. Third, there is, I think, necessity to develop systematic data for us to teach carefully various strategies which is required in the application of this teaching-learning, and necessity to supplement the systematic contents of demonstration model on account of the difficulty which I should arrive at the objective for short hours. In this study, I have ever made teaching-learning model to guide demonstration strategy to be of importance in discussion. Moreover, If we can properly reconstruct ,according to environment, stages and strategies which are suitable for each learners, we can, I think, use this study. Therefore, I expect that my study for this teaching-learning model can give a little help to teaching on demonstration which is difficult.

N/A Objectives: To investigate the patterns of biochemical bone markers, such as urinary deoxypyridinoline (DPD), N-telopeptide of type I collagen (NTX), and serum osteocalcin (OC), bone-specific alkaline pbosphatase (BSAP) in postmenopansal women with hormone replacement therapy (HRT). Materials and Method: From July 1997 to January 1998, total 239 postmenopausal women were emolled in the present study, and 198 healthy premenopausal women with regular menstruation were served as control. The postmenopausal women were pouped into the HRT group and the non-HRT group. The women in the HRT poup have received estrogen with continuous or cyclic progestin therapy far more tban 6 months. The biochemical bone markers of all women were assayed. Results were analysed with Students t-test. Results: The urinary DPD of the non-HRT group was sigaificantly higher than both the HRT poup and the premenopausal group(5.51 +- 2.47 vs. 3.36 +- 1.02 and 4.01 +- 3.86 nM/mM, p < 0.05, repectively). The urinary NTX of the non-HRT group was also higher in comparison to the HRT group and the premenopausal group(48.71 +- 11.54 vs. 33.70 +- 17.43 and 33.70 +- 17.43 nM BCE/mmol, p < 0.05, repectively). However, there were no significant differences in the concentrations of serum BSAP and OC among the three poups. Conclusion: The urinary DPD and NTX were more sensitive indicators of bone metabolism tban serum BSAP and OC in postmenopausal women undergoing HRT.

Newton-Raphson Method와 Matrix를 이용한 고차방정식의 인수분해 기법

장영우,황치정 충남대학교 기초과학연구소 1995 忠南科學硏究誌 Vol.22 No.1

Application of Newton-Raphson iteration, partial differentiation and linear algebra in factoring both real and complex coefficient polynomials is presented. When factorizating complex polynomials, it is shown that calculations can be performed in real arithmetic only. Complex cases expand the matrix size by a factor of two due to the real-numbers-only computation. For complex cases with large matrices, the method to calculate inverse matrix and factor polynomials using quarter matrices is suggested.
