      • 교육실습의 대안적 모색: 1-1-3 실습의 시작과 경과

        최석민 대구교육대학교 초등교육연구소 2021 현장중심 초등교육연구 Vol.3 No.-

        교육실습은 교사를 준비하는 모든 학생이 거쳐야 하는 하나의 통과 의례로 인식되는 경향이 있다. 학교 현장에 대한 직접 경험의 기회 제공이나 대학 수업에서 배운 이론의 학교 적용 등 에서 의의를 찾고 있는 것이 일반적이기 때문이다. 하지만 교육실습은 교생이 현재 학교를 경 험하면서 미래 교육을 준비하여야 하는 이중적 목적을 갖는다는 점에서, 관행적 실습의 현실은 재검토의 필요가 있다. 누구나 알고 있듯, 빠른 시대 상황의 변화는 새로운 교육을 요구하고 있고, 이미 OECD(2005)나 CCSSO(2013)에서 재구조화되었던 바와 같이 교사 역할도 변화되고 있다. 본 연구는 시대적 요구에 변화된 교육적 책무를 담당할 수 있는 교사를 양성하기 위해 본 대학에서 2016년 하반기부터 진행하고 있는 1-1-3 매칭 맞춤형 교육실습과 관련하여, 특히 초 기 기획을 중심으로 핵심적 구상의 내용과 구조화 전략, 그리고 매칭의 목적이 무엇이었는지에 대해 논의하고자 한다. 이미 관련 실습의 실태나 성과와 관련된 보고서(최석민 외, 2019)가 발 간되었다는 점에서, 그 구체적 시행 내용과 방법, 설문 결과 등에 대해 다루기보다는, 보고서에 담고 있지 않은 시작과 경과, 그리고 그 초점에 나타난 고민과 전략이 무엇이었는지에 대한 기 술에 초점을 두고자 한다. 이는 향후 지속될 대안적 교육실습을 기획하기 위한 하나의 참조 자 료를 구성하기 위한 성찰적 기록의 성격을 담고 있다. 주된 내용은 첫째, 1-1-3 매칭 맞춤형 실습의 문제의식과 그 이론적 검토 과정. 둘째, 법령과 내규, 유인과 선발, 연수 등과 같은 실 제적 문제에 대한 구조적 대응 과정. 셋째, 운영에 나타난 사례로 수업실습의 초점 등이다. The education practice tends to be carried out as a passing ritual course that all students preparing for teachers have to go through. It is common to find significance in the direct experience of the school site or the application experience of the theory learned in the university class. However, the current practice of practice needs to be reviewed in that it has a dual purpose of preparing for future education while experiencing the current school. The rapid change of the situation is demanding new education, and the role of teachers is changing as they were restructured in OECD or CCSSO. This study aims to discuss the progress of the concept and structure of the 1-1-3 matching teaching practicum, which has been conducted since the second half of 2016. It focuses mainly on the spirits of reflective teaching based on J. Dewey’s growth and how it could be realized in real situation of now and here in Daegu province. The main contents are as follows: First, what are main focus of 1-1-3 teaching practicum especially on its theoretical background. Second, how the problems on national laws and regulations could be solved. Third, what is the real cooperation example of it. I wish this paper could be as an example for introducing and progressing innovative education practice.

        가스터빈 블레이드 삼각 내부 냉각 유로 종횡비에 따른 열전달 특성

        최석민,최승영,박희승,조형희 대한기계학회 2021 大韓機械學會論文集B Vol.45 No.3

        This study investigated the flow and heat transfer characteristics of the triangular internal passage of the leading edge of a gas turbine blade with respect to the aspect ratio. Aspect ratios of 1:0.5, 1:1, and 1:2 were compared using numerical simulations. The simulations were conducted under the condition of Re = 10,000. The results demonstrated that the 1:0.5 aspect ratio case exhibited higher strength of the secondary flow. Therefore, relatively high heat transfer distributions were observed near the leading edge region. However, the 1:1 aspect ratio case exhibited higher average heat transfer distributions owing to the complex effect of the main flow by the rib and secondary flow. Therefore, the thermal performance ratio is the highest at the 1:1 aspect ratio channel, and we conclude that the 1:1 aspect ratio is suitable for the internal passage of the blade leading edge. 본 연구에서는 가스터빈 블레이드 전단부의 삼각 내부 유로의 종횡비에 따른 유동 및 열전달 특성에 대하여 분석하였다. 종횡비 1:0.5, 1:1, 1:2의 세 가지 유로 형태를 수치해석을 통해 비교하였다. Re=10,000인 조건에서 해석을 수행하였다. 결과를 살펴보면 종횡비가 작은 유로에서 이차유동의 발생이 더 크게 나타나는 것을 확인하였다. 이로 인해 leading edge 부근에서 국소적으로 높은 열전달이 나타나는 것을 확인하였다. 하지만 종횡비 1:1의 유로에서 이차 와류와 요철에 의한 주유동의 열전달 강화 효과가 복합적으로 잘 나타나게 되어 평균적으로 높은 열전달 분포를 보이는 것을 확인하였다. 이로 인해 열성능계수도 가장 높게 나타나는 것을 확인하였다. 따라서 가스터빈 블레이드 전연부의 내부유로의 형태는 종횡비 1:1이 가장 적합하다고 판단된다.

        고리 금속판을 이용한 망치 손가락의 수술적 치료법

        최석민,정성균,김용배,신호성,박은수 대한성형외과학회 2009 Archives of Plastic Surgery Vol.36 No.3

        Purpose: The bony mallet finger injury is generally managed by conservative treatments. But operative treatments are needed especially when the fractures involve above 30% of articular surface, or when distal phalanx is accompanied by subluxation in the volar side. This is the reason why they often result in chronic instability, articular subluxation and cosmetic dissatisfaction. In this report, We describe new method using the hook plate as an operative treatment of mallet finger deformity. Methods: Among 13 patients with mallet finger deformity who came from February 2006 to February 2008, six patients were included in surgical indication. Under local anesthesia, H or Y type incision was made at the DIP joint area. After the DIP joint extension, the hook plate was put on the fracture line, and one self tapping screw was used for fixation. 2 hole plate which was one of the holes in 1.5 mm diameter was cut in almost half and bended by approximately 100˚. Results: In all six cases which were applied the hook plate, complications such as loss of reduction or nail deformity were not seen. In only one patient, hook pate was removed due to inflammatory reaction after the surgery. In 2 weeks after the operation, active motion of DIP joint was performed. The result was satisfactory not only cosmetically but also functionally. In 6 weeks after the operation, the range of motion of DIP joint was average 64˚. Conclusion: The purpose of the operative treatment for mallet finger deformity using the hook plate is to provide anatomical reduction with rigid fixation and to prevent contracture at the DIP joint. While other operations takes 6 weeks, the operation using the hook plate took only two weeks to enable active motion. Complication rate was low and the method is rather simple. Thus, the operation using the hook plate is recommended as a good alternative method for the mallet finger deformity treatment.

        According to perspectives of the fundamental function of schooling and education, the meaning of teachers' morality is radically different. First, One group that considers function of education as transmission of knowledge or initiation into core culture believes that teachers are intrinsically moral if they only can escape from indoctrination. Second, the group under the same assumptions of modernism that has different perspective questions such an approach that ignores the uniqueness, uncertainty, and value-conflict of teaching situation. The latter group emphasizes on "reflect-in, reflect-on and reflect on reflect-in." The third group,, emancipatory approach thinks both of them are insufficient because modernistic approaches to education mean only banking education that neglects the power relationship and deeply seated inequality widely spread in the inner part of schooling. So from this point of view, to be moral teacher means to be a critical transformative intellectual who has moral, political and pedagogical leadership and can change existing systems of education. The last, also criticize on both of modernistic approaches because of their dominancy of masculine biases. With changing not only curriculum structures and contents, but also relationship of teacher-students, this feministic approach wants to change school system of hierarchical relation and abstract knowledge deliverance to that of care giver-and-taker relation and of mutual knowledge sharing. Teacher as acare-giver is intrinsically moral in that care is one of the critical constituents of morality and care-giving means respect students as human being. Even though these four perspectives have conflicting elements, we can't neglect even one perspective in order to have full meanings of morality of a teacher. So I connect these perspectives with the conception of growth.That is because first, growth is in itself moral. Second, growth is open to any activities and is educative only if it is genuine for problem-solver. Third, growth considers students as a moral agent and finally growth can be justified its inclusion of multiple perspectives of moral teacher.
