Seo, Kyoung-Hye 이화여자대학교 사범대학 교과교육연구소 2003 East west education Vol.20 No.-

The present study explores the ways of promoting children's understanding of mathematical symbolism from a constructivist perspective. First, this study examines general tenets of constructivism and more specifically, radical and sociocultural constructivist perspectives. Second, based on a constructivist perspective, it reconceptualizes what it means to know mathematical symbolism. Finally, it explores a constructivist approach to teaching mathematical symbolism. In doing so, the present study offers constructivist teaching methods and strategies for meaningful learning of mathematical symbolism.

숲 체험에서의 수학탐구활동이 유아의 수학능력에 미치는 영향

이혜경 ( Lee Hye-kyoung ) 숭실대학교 인문과학연구소 2014 인문학연구 Vol.43 No.-

본 연구는 숲 체험에서의 수학탐구활동이 유아의 수학능력에 미치는 영향을 확인하는데 목적이 있다. 따라서 다음과 같은 연구문제를 설정하였다. 1) 숲 체험에서의 수학탐구활동이 유아의 수학능력에 어떠한 영향을 미 치는가? 2) 숲 체험에서의 수학탐구활동이 유아의 수학능력 하위요소(대수, 수와 연산, 기하, 측정)에 어떠한 영향을 미치는가? 본 연구는 경기도 시흥시에 위치한 K유치원에서 무선 표집한 만5세 유아 총 40명을 대상으로 하였으며, 사전검사를 통해 동질성을 확인한 후 실험을 적용하고 사후검사를 실시하였다. 검사도구로는 황해익, 최혜진(2007)의 ‘유아그림수학능력검사’를 사용하였으며, 실험도구로는 숲 체험에서의 수학탐구활동 프로그램을 사용하였다. 숲 체험에서의 수학탐구활동은 실험집단을 대상으로 9주간 총 14회 이루어졌다. 수집된 자료는 SPSS 18.0 프로그램으로 t-test를 실시하여 집단 간 차이 검증을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 숲 체험에서의 수학탐구활동을 실시한 실험집단이 통제집단보다 수학능력향상에 긍정적인 영향을 미치는 것으로 타나났다. 둘째, 숲 체험에서의 수학탐구활동은 유아수학능력의 하위요소인 수와 연산에서 유의미한 영향을 미치지 못하는 것으로 나타났으나, 대수, 기하, 측정능력 향상에는 긍정적인 영향을 미치는 것으로 나타났다. 본 연구의 결과, 숲 체험에서의 수학탐구활동은 유아의 수학능력향상에 도움이 되는 효과적인 프로그램인 것으로 확인되었다. 따라서 좀 더 장기적인 기간을 두고 수학능력의 요소가 적절히 배치된 숲 체험에서의 수학탐구활동프로그램을 적용해 본다면, 본 실험에서 평균점수는 향상되었으나 통계적으로 유의미한 결과를 얻지 못한 수와 연산에서도 긍정적인 결과를 얻어 유아의 수학능력 향상에 더욱 효과적인 수업전략이 될 것이다. The purpose of this study was to confirm the effects of mathematical inquiry activity in forest experience on young children's mathematical ability. Accordingly, the following research problems were established. First, Which influence does mathematical inquiry activity in forest experience have on young children's mathematical ability? Second, Which influence does mathematical inquiry activity in forest experience have on sub-elements(algebra, number and operation, geometry, measurement) in young children's mathematical ability? The participants of this study were 40 5years old children who were selected randomly at K kindergarten where is located in Siheung-si, Gyeonggi Province. Post-test was carried out by applying it to experiment after confirming homogeneity through pre-test. A test tool was used ‘Pictorial Math Ability Test for Young Children’ by Hwang Hae-ik and Choe Hye-jin(2007). Experimental tool was used a program of mathematical inquiry activity in forest experience. The mathematical inquiry activity in forest experience was composed of totally 14 times for 9 weeks targeting the experimental group. The collected data were carried out t-test with SPSS 18.0 program and were verified group-based difference. The results of this study, they are as follows. First, compared to the control group, the experimental group with execution of mathematical inquiry activity in forest experience was indicated to have positive influence upon improvement in mathematical ability. Second, the mathematical inquiry activity in forest experience was indicated to fail to have significant influence upon number and operation, which is sub-element of young children's mathematical ability, but was shown to have positive influence upon improvement in ability of algebra, geometry, measurement. As a result of this study, the mathematical inquiry activity in forest experience was confirmed to be effective program of being conducive to improvement in young children's mathematical ability. Accordingly, given trying to apply the program of mathematical inquiry activity in forest experience, which is suitably distributed the elements of mathematical ability, with having a little longer term, a positive outcome will be obtained even in number and operation that failed to obtain statistically signifiant result even if the mean score was enhanced in this study, resulting in being more effective teaching strategy for improving young children's mathematical ability.

문화재의 생물피해 예방에 주로 활용되는 壎蒸消毒[메틸브로마이드와 에틸렌옥사이드 혼합 가스]이 書畵類에 어떤 영향을 미치는지에 대하여 간략한 調査를 실시하였다. 彩色이 있는 조선시대 古地圖와 繪畵 등 13점을 대상으로 훈증소독 前과 後의 顔料의 變色 또는 退色의 有無 그리고 종이의 pH변화 등에 대하여 測定하였다. 그 結果 旣存의 문화재 훈증소독 適用基準[가스의 湯度, 暴露시간 등]을 지킨 조건에서는 안료의 변·퇴색 현상을 발견하지 못했으며 종이의 酸性化에도 영향을 미치지 않는 것으로 확인되었다. This is a brief study on the influence of fumigation (using mixed gas of methyl bromide and ethylene oxide) on old paintings. Fumigation is principally used to prevent biological damage of objects. Thirteen objects, including old colored map from Choson Dynasty and some paintings, were selected for this research. Before and after fumigation, color measurements were made and changes of pH value were measured. The result is that the fumigation did not affect on discoloration of colored area and acidity of paper, as far as the standard of application (such as concentration of gas, exposing time and ect.) of fumigation was kept.

『억척어멈과 그녀의 자식들』에 나타난 자식을 잃은 어머니의 탈신화화

이혜경 국립7개대학공동논문집간행위원회 2003 人文學論叢 Vol.3 No.-

Even though Bertolt Brecht have been aware of a dynamic women's movement and tradition, the role of woman in his plays is restricted to the female gender. In his most successful plays, the female subject is identified as an asexual mother, or as a sexual being who willingly abandons her sexuality. Mothers are central to plays in which they are no longer sexual objects but become objects of political demonstration with suppressed emotional lives. Brecht's depiction of female characters discredits the mythical status of woman. Among the single mothers in Brecht's dramatic creation, Mutter Courage is a complex character who has vitality, shrewdness, wit, and boldness. There are two dominant traits in her character; as a cold-blooded trades-woman and a nurturing mother. Despite the title itself, the combination of 'mother' and 'courage,' Mutter Courage does not conjure up the emotional dream of the maternal, courageously fighting for or defending her children. With grimly constricted motive-'My aim in life is to get through, me and my children and my wagon,' the title character expresses her resignation to a life of mere survival, nothing more. She pulls her wagon through the Hundred Year's War, changing sides indiscriminately whenever sales drop, because she, as a war profiteer, lives and acts as if the condition of war is both natural and inevitable. And she curses the war, or the peace, without taking a moral stand for or against either state. Mute Catherine's successful move to save the children of Halle supplies a sharply contrasting counterpoint to Mutter Courages's bootless attempts to shield her offspring from the maw of war. Courageous action of Catherine provides the only sovereign act of altruism in the entire play. Having lost her three children one by one, Mutter Courage ends up the only survivor of her family. But she fails to arrive at the ultimate 'anagrorosis,' for she has learned nothing from the disasters that befall her. Mutter Courage herself, who is ironically involved in a business deal each time one of her children is killed, turns out to be the principal representative of self-defeating recessive functions. Brecht wanted to direct attention to the 'mercantile nature of war' and to show the foolishness of the clever tradeswoman-mother, a self-centered schemer who remains driven by her survival instinct but loses her three children in the process. The figure of Mutter Courage, however, has aroused attraction instead of repulsion, sympathy rather than antipathy, and pity instead of condemnation, although Brecht didn't want the audience to sympathize with Mother Courage. Audiences have seen her as the symbol of 'warm-blooded mother animal,' battered by the forces of war and big business, who gets up from near-death to keep going. While Mutter Courage firmly believes her survival to be dependent upon the continuance of her vacillating stance towards war and business, her conflict always turns around the axle of a cowardly and hopeless outlook on life. Through the characterization of Mutter Courage, whose motherhood is ironically established, Brecht wanted to reveal the structure that could bring out the true nature of things; the war is meaningless and people learn nothing from catastrophes.

This paper estimates dynamic object information in video stream and proposes face detection technique using dynamic GTM(genetic tree-map) algorithm. The existing general object estimate methods divided image information through cluster process, and estimated as reconstructing the moving object of the separate information. On the other hand, proposed method obtains object information that is moving in video stream as taking advantage of BMA(b1ock matching algorithm) and employs PCA(principal component analysis) as cluster algorithm. PCA algorithm searches for principal components utilizing statistical properties for input data, and then divides data making use of region division algorithm. Only face region is detected in specific object abstracted using separate object information, according to dynamic GTM map information generated about feature of face region using dynamic GTM.

김혜경 광주보건대학 1996 論文集 Vol.21 No.-

The purpose of this study is to analyze songs presented in sixth curriculum according to the children's developmental level and the elective items. The analyzed points of songs are five : content, tonality, form, beat, vocal range. The results and suggestions can be summarized as follows. 1. The contents of songs are almost nursery rhymes. The more various branches of songs are needed. 2. The tonalities of some songs are not appropriate to children's development. Children can sing easily the song formed as fundamental tonality. 3. The forms of songs are not appropriate to children's musical ability. The more shorter forms of songs are needed. 4. The beat of songs is mostly appropriate to children's development. 5. The vocal range of songs is mostly appropriate. But the reduced ranges are needed to sing more easily.

『햄릿』에 나타난 지연의 리듬

이혜경 한국외국어대학교 외국문학연구소 2003 외국문학연구 Vol.- No.13

The purpose of this study is to widen the interest from Hamlet's delay and its cause to the whole work, whose arrested actions and speeches set the main rhythm of the play. Extraordinarily strong and even vowed purposes of the major characters reach the point of a kind of frustration or standstill, and numerous actions are not generally brought to their decisive fulfillment until the finale. The accusation of delay or the popular reputation for indecisiveness stems are mostly from Hamlet himself. The central instance of the rhythm of Hamlet's own actions are brought out when he is about to stab Claudius when Praying but yet, made a halt. But Hamlet is the only character in the play who delays his accomplishment of what he sets out to do. Fortinbras's plan for military action and Laertes's attack on Hamlet in the graveyard are halted and deferred. Claudius also seems to postpone the killing of Hamlet, though he sends Hamlet to England. Within the rhythm of delay, the effect of many delay exits and dynamic pauses in the play have distinctively and variously achieved in the theatre. Although the play seems soliloquies, with long speeches, digressions, and self-conscious comment on the diction, most of the narration in this play are distressed or restrained. For all more than 3700 lines, the loquaciousness of the play postpones what was needed to be spoken. Many of the characters, however, have an extended and extravagant utterances, like Laertes's 'Speech of fire' and Ophelia's bawdy songs. Shakespeare's dramaturgy of delay contributes our sense of a world in which direct action and communication are extremely difficult, while drawing attention to 'a passionate speech' and performance. Interrupted purpose of the strongest characters remains suspended in our minds until it is carried out abrupt, almost inadvertent completion that seems to come out from itself. Yet Hamlet's last explanatory public oration, which he most wants to say, is captured in the final stage. It was left to Horatio to report him and his non-deterred acts, but Horatio's own report to unknowing world should, however, be promised but deferred. A basic rhythm of delay share the dominant characters in their primary conflicts. The rhythms of action and speech re-enforce one another and interwork with the atmosphere of prolonged aftermath The play practices economies based on parallelism among characters, recurring situations, reflexivity, and thrifty structure, while also pursuing a deliberately dilatory style. Dilatory rhythm in Hamlet multiplies and varies our perspectives on it.
