본 연구의 목적은 과제 유형에 따른 상호적 또래교수활동을 통해 고등학교 1학년 학생들의 수학적 추론 능력이 어떻게 변화하는지를 관찰, 분석하고 이를 통해 교수학습활동상의 유의점과 시사점을 모색하는 것이다. 연구는 사전검사 및 활동안내, 상호적 또래교수활동 순으로 진행하였으며, 상호적 또래교수활동은 과제 유형별로 매주 2차시씩, 총 4주간 진행하였다. 각 추론 과제 유형에서 학생들의 활동 내용 중 추론 수준에 변화를 주었다고 판단되는 문제들에 대해 집중적으로 분석한 결과, ‘추측하기’에서는 귀납적 추론과 유비적 추론 능력에 대한 변화를 가져올 수 있으며, ‘추측조사하기’와 ‘논증개발하기’에서는 추론에 대한 선제적 판단을 비롯한 연역적 추론 능력을 변화할 수 있음을 확인하였다. 또 ‘논증평가하기’에서는 오류확인과 실수정정과정에서 개념과 문제 상황을 비교해나가는 과정을 거치며 수학적 추론 능력에 변화를 보였다. 본 연구를 통해, 상호적 또래교수활동을 추론 능력 함양에 활용할 때 교수학습 상의 유의점으로서 첫째, 학생들의 개념 이해가 부족한 경우 추론 활동이 정체될 수 있으며 둘째, 잘못된 추론 결과를 무비판적으로 받아들이는 경우가 발생할 수 있고 셋째, 추론 과정에서 소모적 논쟁이 발생할 수 있음을 알 수 있었다. The purpose of this study is to provide specific implications by observing and analyzing how the mathematical reasoning abilities of the first grade students in high school change through reciprocal peer tutoring activities. The research was conducted in the order of pretest, activity guide, and reciprocal peer tutoring activities, and the reciprocal peer tutoring activities were conducted for a total of four weeks, two periods a week for each task type. As a result of this research, we confirmed that reciprocal peer tutoring activities has had a positive effect on the mathematical reasoning abilities of the first graders in high school. In the stage of making a conjecture, they had an influence on change in inductive and analogical reasoning abilities. In the stage of investigating a conjecture and developing an argument, they can affect deductive reasoning abilities as well as anticipative judgment on reasoning. In the stage of evaluating an argument, they had an influence on change in mathematical reasoning abilities by comparing basic concepts and the given situation of the questions in the process of finding errors and correcting a mistake. The considerations for teaching and learning when using reciprocal peer tutoring activities to enhance students’ mathematical reasoning abilities were discovered. First, reasoning activities can be delayed when students have lack of understanding mathematical concepts. Second, students can accept the wrong result of reasoning unsuspectingly. Finally, unnecessary disputes can be made during reasoning.

This study was to analysis a difference of sport activity self-management by the exercise participation types of elementary school students and a hierarchy influence effecting on the sport selfconfidence. Subjects were selected from six regions(Seoul, Pusan, GyeongNam, GyeongBuk, JoenNam, Jeju) and divided into three groups such as school athletic group(n=187), sport-gifted group(n=185), after school sport club(n=216). The questionnaire was used a Physical Activity Self-management of elementary students(Ahn, Jung, 2016), and data analysis was used by SPSS Ver.21.0. One way ANOVA and hierarchy regression analysis were conducted. The following results were obtained. First, Male sport-gifted group was significantly higher(p<.001) than school athletic group or after school sport club in parents support, life management, amusement, personal management. Second, Female sport-gifted group was significantly higher(p<.001) than school athletic group or after school sport club in parents support, life management, amusement, selfconfidence, personal management. Third in the factor of exercise management, sport-gifted group and school athletic group were same level and significantly higher(p<.001) than after school sport club. Fourth on the sport self-confidence, the amusement was the strongest influence factor and next was the exercise management, after next was the personal management.

라캉적 승화

안정인(Ahn, Jeong-Inn) 새한영어영문학회 2012 새한영어영문학 Vol.54 No.4

This is a study on the homology of psychoanalysis and aesthetics especially from the viewpoint of the Lacanian psychoanalytic theory. Lacan opened his Seminar Ⅶ, The Ethics of psychoanalysis, by drawing attention to the psychoanalytic experience attempting to restore to favor in the strongest possible way the productive function of desire as such. He returned to Freud with Kantian perspective on the ethics and the beauty in his Critique of Judgement. Lacan proposed the concept of sublimation as the ethics of psychoanalysis defining it as “the satisfaction of the drive with a change of object, that is, without repression.” With a change of object, an object can be raised up to the Thing. Lacan’s sublimation is dialectically articulated between desire in the symbolic and drive in the real. The real is that which resists symbolization; it is the traumatic kernel at the core of subjectivity and the symbolic order. The real is thus associated with the death drive and jouissance as the ultimate, unspeakable, limit of human experience with the failure of our desire - and it is through fantasy and the object a that the subject sustains himself in this impossible scenario Lacan praised the splendor of Antigone related to the sublimation. She shows the ideal image by her act according to the ethics of psychoanalysis. The paradox is in that it is the ethics of transgression. It is related to the death drive beyond the pleasure principle. Lacan regards the notion of the death drive as a creational sublimation. Psychoanalysis and aesthetics can meet in the dimension of absence that indicates the necessity of the creation ex nihilo. According to Lacan’s explanation, the appearances of the beautiful creates two things that go together: the something and the void, the emptiness inside it. With every creation, the space in-between gets created. This is why in relation to the phenomenon of the beautiful Lacan speaks of the fantasy which he formulates in terms of a beauty that must not be touched. The splendor of beauty is a kind of shield that the artist and the spectator raise at the very point of das Ding. This shield is made to stop desire: desire, as it were, stops at beauty and remains with it, not wishing to go any further. It is not that the desire for the beautiful is suspended, but rather that desire is suspended, frozen within the realm of the beautiful. This is the effect of beauty on desire.

안정용(Jeong-Yong Ahn) 한국엔터테인먼트산업학회 2009 한국엔터테인먼트산업학회논문지 Vol.3 No.3

본 연구에서는 기존의 연구들을 통해 그 효과가 입증된 구성주의 교수학습 방법을 통계학 과목에 응용하는 예를 제시하고자 한다. 통계학 분야에서 구성주의 교수학습 방법을 교실수업에서 쉽게 적용하기 위해서는 정보기술의 활용이 필수적이다. 따라서 문제위주 학습과 협동학습 등을 통해 학습자의 참여와 학습효과를 높일 수 있는 웹 기반 학습콘텐츠를 개발하 고 활용하는 사례를 제시한다. This article is to present a learning model based on constructivism in a statistics course. To apply the model in the statistics field, the peer assessment technique which was applied to students enrolled in a mathematical statistics course, we have to use the information technologies. In this paper, we present a prototype of the learning contents based on the Web. The contents help to enhance the participation of learners and learning effect by supporting the problem-based learning and cooperative learning.

Recently, dynamic proxy caching has been proposed in the distributed environment so that requested media objects may be served directly from the proxy without access to the server. However, efficient caching becomes more difficult due to large multimedia size, low latency and continuous streaming demands of media objects. To solve the problems caused by streaming demands of media objects, this paper proposed a grouping scheme with fuzzy filtering based on partition and mapping. The proposed scheme divides media block segments into fixed partition reference block(RfP) and variable partition reference block(RvP).

안정용(Jeong-Yong Ahn) 한국엔터테인먼트산업학회 2009 한국엔터테인먼트산업학회 학술대회 논문집 Vol.3 No.1

In this study, we compare the assessments made by self, peer and instructor in a probability theory course. The goal is to investigate the following two questions: (1) Is it reasonable or fair to expect students to be responsible for assessing the work of their colleagues and themselves? (2) What are students’ opinions about the learning effect after they participate in the assessment process? As part of the study investigating these questions, we designed a prototype for a Web-based assessment tool and a procedure to apply the assessment techniques in a probability theory course. In addition, we collected and analyzed the data produced in the assessment processes from students and the instructor.
