Paul Ernest의 수학적 지식 구성과정에 대한 교수학적 고찰

박정선(Park Jeongseon),신재홍(Shin Jaehong) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.20

본 연구는 Ernest의 수학적 지식 구성과정 모델이 교실의 교수·학습 상황에서 동일하게 적용가능한가에 대한 의문에서 시작하였다. 연구의 목적은 학생의 수학적 지식 구성과정을 설명하는 대안적 모델을 제시하는 것이다. 이를 위해 Ernest의 모델 에 대한 이론적, 교수학적 고찰을 시도하였고 학생의 지식 구성과정을 명확히 하였다. 그 결과, 첫째, 학생은 주관적 지식을 구성하나 Ernest의 모델이 제시한 객관적지식을 스스로 구성한다고 볼 수 없다. 둘째, 교사의 개입 하에 학생은 주관적 지식 과 구별되는 객관성을 갖는 지식을 형성할 수 있고, 이를 Ernest의 객관적 지식과 구별하여 ‘1차-객관적 지식’으로 명명하였다. 셋째, 교실공동체의 가장 큰 특징은 교사의 존재로, 교사와 학생 간의 비대칭적 상호작용 과정을 통해 지식이 구성되고, 이를 ‘기울어진 협상’으로 표현하였다. 이를 반영한 ‘학생의 수학적 지식 구성과정 모델’을 제시하였다. This study begins with the question whether Ernest s mathematical knowledge construction process model is equally applicable in the teaching and learning situations of the classroom. The purpose of the study is to present an alternative model that describes a student s mathematical knowledge construction process. For this purpose, theoretical and pedagogical considerations on Ernest s model were attempted to clarify the process of constructing students’ knowledge. The results indicate that students construct their own subjective knowledge but do not construct objective knowledge of the Ernest’s model by themselves. Second, students are regarded to construct the knowledge entailing objectivity to a certain degree under teacher intervention and we name it as the first–order objective knowledge distinguished from the objective knowledge in the Ernest’s model. Third, one of the most salient features of the classroom community is the existence of a teacher, and thus we describe the asymmetrical interactions between a teacher and students as unequal negotiation . A model of student s mathematical knowledge construction process was presented.

박정선(Jung-Sun Park),이동주(Dong-Joo Lee),임종빈(Jong-Bin Im) 대한기계학회 2005 대한기계학회 춘추학술대회 Vol.2005 No.5

The effectiveness of Response Surface Method(RSM), one of optimization methods recently watched, is verified in various fields in that it has semi-global and discrete characteristics. The choice of the regression model and the plan of Design of Experiments(DOE) are primary factors which have a considerable effect on the optimization. Therefore, many studies are being continued since the development of RSM. In particular, a suitable build of DOE is a potent influence of convergence time and its confidence. In this paper, two ways are suggested to make the algorithm more efficient. The first is about a collecting method of sampling data which determines the form of regression model and the other is about construction of the trust region in order to improve reliance. The merge algorithm is developed on this study so that run sequentially and used in fundamental research to acquire more improved technique.

권환의 초기문학과 진전(鎭田)의 문화 환경

박정선 ( Park Jung-sun ) 한국문학언어학회(구 경북어문학회) 2018 어문론총 Vol.77 No.-

이 논문의 목적은 권환이 사회주의와 프로문학의 길로 나아가게 된 배경과 과정을 그의 고향인 진전(鎭田)의 문화 환경과 관련하여 살펴보는 데 있다. 권환은 넓고 비옥한 토지, 오랜 혈연공동체, 교통의 요충지를 특징으로 하는 진전의 문화 환경 속에서 나고 자랐다. 그런 문화적 환경은 그에게 농경적 정서, 공동체 의식과 감각, 낯선 것에 대한 호기심을 갖게 해 주었다고 본다. 그리고 그는 아버지 권오봉과 그가 세운 경행학교를 통해 민족교육을 받고 민족적 소명의식을 갖게 되었다. 그 같은 고향의 장소성과 성장기의 체험은 후일 그로 하여금 식민지 민중의 비참한 현실에 관심을 갖게 했고, 그러한 현실을 다룬 이른바 빈궁문학 작품을 쓰게 했다. 그는 경행학교를 마치고 중동학교와 휘문고등보통학교, 야마가타고등학교를 거쳐 교토제국대학에 진학했다. 그는 이 10여 년의 유학시절 동안 문학에 뜻을 세우고 부지런히 작품을 쓰고, 투고했다. 그런 과정에서 등단 작 「아즈매의 사(死)」(1924)가 탄생했다. 이 소설은 식민지 민중의 빈궁을 연민 어린 시선으로 그려낸 작품인데, 그 뒤에 발표한 작품들도 거의 이런 경향에 속한다. 그리고 등단 무렵의 작품들은 대부분 강고한 현실에 패배하는 인물을 그렸다면, 1920년대 말로 갈수록 폭력적인 방식이긴 하지만 현실에 적극적으로 저항하는 인물을 그리는 것으로 작품 경향이 변화한다. 에른스트 톨러의 혁명적 문학에 심취한 결과이다. 또한 그는 당시 일본 지식계에 영향을 끼치던 사회주의를 이념적 무기로서 받아들인다. 그에 따라 그의 문학에서 현실에 대한 저항의 방식도 개인적 폭력에서 조직적 투쟁으로 변화한다. 이때가 1929년이며, 그의 문학적 여정에서 초기문학 시대가 끝나고 프로문학 시대가 시작되는 시점이다. The purpose of this paper is to examine the background and process of Kwon Hwan’s choice of socialism and proletarian literature during the Japanese occupation in relation to the cultural environment of his hometown, Jinjeon. Kwon Hwan was born and raised in the cultural environment of Jinjeon, which features wide and fertile land, a key place for transportation, and an old blood-linked community. Such a cultural environment made him a man rich in emotions, a man curious about strangers, and a man of community consciousness and sense. And he received a national education from nationalist teachers, including his father, at Kyenghayng School in Jinjeon, and had a sense of national mission. Such a placeness of his hometown and his experience of the growth period later led him to pay attention to the miserable realities of the colonists, and to write an literature of poverty dealing with such realities. He graduated from Kyenghayng School, went to Kyoto Imperial University through Joogdong School, Whimoon School, and Yamagata High School. During this period, he aspired to be a writer and devoted himself to writing and contributing. His first work, Azmae's Death(1924) was born in the process. This novel depicts the poverty of the colonists with a compassionate gaze, and the works published after that are almost in this trend. And early works depicted the characters who are defeated by strong realities. But as the end of the 1920s, his works changed to portray people who actively resist reality, even though they are violent. That's because he was absorbed in Ernst Toller’s revolutionary literature. He also embraces socialism as an ideological weapon that influenced Japanese intellectuals at the time. Accordingly, the method of resistance to reality in his literature changed from personal violence to organized struggle. This point is the year 1929, when the era of early literature ended and the era of proletarian literature began in his literary journey.

Lee Ju-hong was a writer that led the juvenile literature of socialism during Japanese colonial rule. Also he edited a media of juvenile literature, Sinsonyun, contributed his works to Sinsonyun and Byeolnara. Thus Sinsonyun and Byeolnara were closely related with Lee Ju-hong`s literature in the 1930`s especially. However, there has been little discussion about this research so far. The aim of this thesis is to explain the relationship between Lee Ju-hong and a media of juvenile literature. Lee Ju-hong joined a magazine company, Sinsonyunsa, in June, 1929. He was a magazine editor. The magazine company has been strengthened socialism at this point of time. At this time, his literature was showed various tendency. His collection of children`s song was reflected innocentism, his children`s story, juvenile drama and novels were showed illuminism and realism. He published a juvenile novel of socialism in 1930. By this time, his ideology was changed to socialism. It is closely connected with transformation of Sinsonyun. He resigned and then he returned to his home in the late 1930`s. But he has still edited magazine after that. Besides, he joined as a co-author in Bulbyeol. His children`s song was a tendency of socialism completely at this time. After that, he extended to contribute his works to Byeolanra. He came back to Seoul in September, 1932, and he created prolificacy in writing. The theme of his literature at this time was showed legitimacy of Marxism and socialism, class hatred of landlord profiteering and solidarity of the weak. All of these works are recorded in Sinsonyun and Byeolnara.

시설분만 농촌산모들의 도시분만기관 선택에 관한 연구

박정선 ( Jung-sun Park ) 한국보건사회연구원 1991 保健社會硏究 Vol.11 No.2

농촌지역의 시설분만율은 해마다 늘어나고 있는데, 저렴하고도 안전한 분만을 위해 농 · 어촌에 건립된 모자보건센터에서의 분만개조실적은 반대로 감소추세에 있다. 그렇다면, 농촌산모들은 도대체 어디에 있는 어떤 분만시설에서 출산하고 있는가? 분석대상자 총 4,091명중 3,090명이 분만을 위해 타지역으로 떠났으며, 이 중 1,946명은 중소도시, 645명은 대도시의 분만기관을 이용하였다. 그들은 거주지역에 종합병원이 있어도 지불능력요인(의료보험)과 교통편의요인(거주지역의 주민 1,000명당 자동차 등록수) 및 인접도시유인요인(가까운 중소도시까지의 거리)에 의해 도시지역 분만기관을 선택하는 경향임이 밝혀졌다. This study examines the decisions of rural pregnant women to seek obstetric care elsewhere, especially in an urban area. The principal data source was “The Patients Survey in 1988”, a nation-wide data collection. Among 4,091 rural pregnant women 3,090 wo-men left their home counties for obstetric care: 1,946 women to small or medium-sized cities, 645 to large cities. Multivariate techniques were used to examine the factors related to selecting urban obstetrics care. The analysis shows that younger, abnormally delivered women were more likely to seek urban obstetrical facilities. In addition, medical insurance, the number of registered cars per 1,000, the number of general hospitals in the county, and the distance to the nearest large city were positively related to the decision to go to any city, but distance to the nearest small or medium-sized city had a negatively significant effect on urban obstetrical service utilization.
