The purpose of this study was to investigate the effect of the STEAM program based on backward design on students’ academic achievement and scientific attitudes in 3rd grade ‘Life of Animals’ unit of the elementary science. To accomplish this, the STEAM program, which is composed of unit objectives, question development, evaluation planing, learning experience, and class development according to the backward design stage, was developed for a total of nine sessions. As a result of the post-test of the academic achievement and scientific attitudes of the group participating in the STEAM program and the group participating in the traditional lesson, there was no meaningful difference between the two groups in academic achievement, but the experimental group significantly improved in the scientific attitudes than the comparative group. It can be seen that the STEAM program based on the backward design had a positive effect on the students’ scientific attitudes. In the other area of elementary science, if we recognize the usefulness of prior evaluation plan of backward model and develop and apply the STEAM program in class development, students will be more interested in science lessons and can enhance learning ability.

연구목적: 본 연구에서는 하악의 동일한 부위에 4개의 임플랜트를 식립하여 임플랜트 피개의치를 설계하는 경우, 바 구조와 이중관 구조 간의 응력분포에 대해 비교 분석하고자 하였다. 연구재료 및 방법: 하악골, 하악골에 식립한 4개의 임플랜트, 일차고정의 바 연결 상부구조, 이차고정의 이중관 상부구조를 삼차원 유한요소 모델링하였고, 상부 구조물에 최대 교두 감합위를 재현하는 수직하중과 측방운동시 작업측의 군기능을 재현하는 경사하중을 가하고, 최대 응력과 응력분포를 하악골, 임플랜트 지대주, 임플랜트 상부 구조물에서 분석하였다. 결과: 1. 악골에서의 최대 응력값은 경사하중을 제외하고 수직하중과 작업측 경사하중에서 이중관 구조가 바 구조에 비해 다소 적은 응력값을 보였다. 이중관 구조가 바 구조에 비해 비교적 악골 전체에 고르게 응력이 분포되었다. 2. 지대주에서는 모든 하중 조건에서 이중관 구조가 바 구조에 비해 낮은 응력값을 보였다. 응력 분포 양상은 두 구조에서 모두 비슷한 양상을 나타내었으며, 최후방 지대주의 원심면에 응력이 집중되었다. 3. 상부구조물에서는 모든 하중 조건에서 이중관 구조가 바 구조에 비해 높은 응력값을 나타냈다. 그러나, 바 구조에서는 바의 각 중심부와 지대주와의 연결부위, 지대주의 치경부에 응력이 집중된 반면, 이중관 구조에서는 상부 구조물 전체에 비교적 고른 응력 분포를 보였다. 결론: 본 연구 결과 이중관 구조가 바 구조보다 악골과 지대주에서는 더 낮은 응력을, 상부 구조물에서는 더 큰 응력을 나타냈다. 상부 구조물에 비교적 크게 전달되는 응력을 견딜 수 있는 상부구조물의 설계와 재료 선택만 이루진다면, 응력분포 면에서 이차고정을 하는 이중관 구조가 일차 고정하는 바 구조에 비해 유리하리라 생각된다. Purpose: The purpose of this study was to investigate the stress distribution in mandibular implant overdentures with telescopic crowns compared to bar attachment. Material and methods: Three-dimensional finite element models consisting of the mandibular bone, 4 implants, and primary bar-splinted superstructure or secondary splinted superstructure with telescopic crowns were created. Vertical and oblique loads were directed onto the occlusal areas of the superstructures to simulate the maximal intercuspal contacts and working contacts such as group function occlusion. Maximum stress and stress distribution were analysed in mandibular bone, implant abutments, and superstructures. Results: 1. In comparison of von Mises stress on mandibular bone, telescopic overdenture had a little lower stress values in vertical load and working side load except oblique load. In the mandible, the telescopic overdenture distributed more uniform stress than the bar overdenture. 2. In comparison of von Mises stress on implant abutments, telescopic overdenture had much lower stress values in all load conditions. In implant abutments, the telescopic overdenture distributed stress similar to the bar overdenture. Stress was concentrated on the distal surfaces of the posterior implant abutments in both mandibular overdentures. 3. In comparison of von Mises stress on superstructures, the telescopic overdenture had much more stress values in all load conditions. However, the telescopic overdenture distributed more uniform stress on superstructure than the bar overdenture. In the bar overdenture, stress was concentrated on each cental area of bar structures and connected area between implant abutments and bar structures. Conclusion: In the results of this study, the telescopic overdenture had lower stress values than the bar overdenture in mandibular bone and implant abutments, but more stress values in superstructures. However, if optimal material was selected in making superstructures, the telescopic overdenture was compared to the bar overdenture in stress distribution.

사회문화적 맥락에서 본 초등학교에서의 교육실습 경험의 의미 탐색

오정란 한국교육사회학회 2003 교육사회학연구 Vol.13 No.3

교육실습 기간 동안 교생들이 갖는 실습경험들은 일상적인 교실 수업 상황에 제한시켜 교사로서의 직무수행을 위해 필요하다고 요구하고 있는 지식과 기술적 능력을 훈련하기 위한 맥락에서 주어지고 있는 것으로 나타났다. 사실 교육실습 동안 이러한 일상적 직무수행 관련 능력의 습득을 강조하는 것은 교생실습의 의미를 교생의 본질적 수업능력의 개발의 맥락보다는 학교사회의 일상적이고 권위적인 관행들에 적응하도록 하는 맥락에서 찾고 있음을 알 수 있다. 결국 교생이 실제로 무엇을 경험하느냐는 현 교직사회에서 구성원들에 의해 공유되고 전수되고 있는 규범 및 관례 등에 의해 영향을 받는다고 할 것이다. 따라서 교생들에게 기대되는 교실수업 현장의 규범이나 실제들은 교생들의 실습경험을 구성하는 맥락이 되고 있으며, 교생의 실습경험은 학교사회의 일상적이고 획일적인 관행들과 복잡하게 연결되어 있음이 시사되고 있다.Ⅴ. 실습경험의 사회문화적 맥락

한국의 학교선택, 어떻게 이해할 것인가

The purpose of this study was to understand the effects of school choice on reproducing, reinforcing, and mediating educational inequality and to propose some issues and concerns embedded in school choice in Korea. First, this study examined the change in social and political conditions that has led to strong support for school choice recently from the two theoretical approaches of market theory and reproduction theory. Then based on previous researches, social issues and concerns pertaining to school choice were critically analyzed with the focus on the competition between schools and the choice of parents as consumers. The results showed that reproduction of inequality under school choice is related to the neo-liberalist trend in socio-political thought since the 1980s, cultural asset of parents as consumers, and reorganization of the school choice system in accordance to the changing demands of parents. Second, when examining the current status of school choice in Korea, it was discovered that there was a lack of equality and diversity in choice, despite attempts at diversification and specialization of the secondary school choice system. Instead, due to the weakening of student selection process and the highly competitive nature of the education system, there is intense competition for admission to a select number of highly competitive and selective educational institutions. Also, it was discovered that due to the increasing influence of parent’s cultural assets in the selection process, the education gap between the classes is on the rise. Therefore, to prevent school choice from reproducing social inequality, positive analysis needs to be carried out within the context of the various social conditions that support school choice in order to search for an alternative that would strength the role school choice plays in promoting impartiality, diversity, and equality of education. 이 연구는 ‘교육기회의 공정성이나 교육의 평등에 미치는 효과와 관련하여 학교선택은 현존하는 불평등을 완화하기보다는 오히려 불평등을 확대시킬 수 있다’는 최근 논쟁이 되고 있는 학교선택 이슈에 대하여 ‘우리의 학교선택은 어떻게 이해할 수 있는가’라는 질문에서 출발하였다. 먼저, 최근 학교선택이 강조되는 맥락을 사회적, 정치적 변화와 관련하여 두 이론적 관점 ―시장이론, 불평등 재생산론― 에서 살펴보고, 학교선택에 관련된 기존의 연구결과들을 바탕으로 학교선택에 내재되어 있는 사회적 이슈와 쟁점들에 대하여 비판적으로 분석하였다. 그 결과 최근 학교선택의 불평등 재생산 이슈는 1980년대 출현한 신자유주의적 사회정치적 상황, 소비자로서의 학부모의 문화자본, 이에 대한 학교선택체제의 재편방식 등과 결합되어 있음이 확인되었다. 그리고 이에 근거하여 한국의 학교선택 현실이 어떤 특징과 양상으로 전개되고 있는가에 대하여 살펴본 결과, 한국의 학교선택 상황은 학교선택체제의 다양화, 특성화 경향에도 불구하고 선택의 다양성과 공정성이 결여되어 있고, 학교선발기능의 약화와 경쟁적 교육체제로 인하여 특목고, 자립형사립고 중심의 선발경쟁의 성격을 띠고 있으며, 선발과정에서 학부모 문화자본의 영향력의 증대로 계층 간 교육격차가 더욱 심화되는 징후를 보이고 있음을 알 수 있었다. 따라서 학교선택을 통한 사회적 불평등 재생산적 징후들을 극복하기 위해서는 학교선택이 강조되는 다양한 사회적 맥락에서 실증적인 분석을 토대로 학교선택의 공정성, 다양성, 평등성을 강화하기 위한 구체적인 대안들을 모색하는 노력이 필요하다고 본다.

The Vegetarian, authored by Han Kang, is a serial novel that won the 2016 Man Booker Prize. While the previous studies focused on the contents of The Vegetarian, this paper provides a new, glossematic interpretation of The Vegetarian. Focusing on the variation of the linguistic symbols contained in The Vegetarian such as the personage nouns, the problems between the tense and the viewpoint, transcription style, and so forth, this paper illustrates the prominent role of In-hye, who tends to be regarded as a background character. By shifting the focus, this paper proposes In-hye’s role as another main character in The Vegetarian along with Yeong-hye. Also, this paper redefines the topic of The Vegetarian through the analyses of the symbolic value of the “White-Eye event” and the difference between “becoming a flower” (in Mongolian Spot) and “becoming a tree” (in Tree Flame). That is, a true vegetarian refers to a state of living a life in harmony with nature, by overcoming the inherent predatory nature of humankind, the top-of-the-food chain predator. The Vegetarian illustrates how the two sisters, Yeong-hye and In-hye, overcome such inherent predatory nature of humankind, and in so doing suggests that an ideal state of living a life is to become “coexisting tree-like brothers.”

A Comparative Analysis of Sowol’s and Yisang’s Poems from a Semiotic Perspective: Focusing on the relation between ‘ending form’ and ‘poetic image’ Jungran Oh (Kwangwoon University) This paper conducts a comparative analysis of Sowol’s 165 poems and Yisang’s 83 poems with a view to demonstrating that the image of a poem is constructed not only with its contents but also in its usage of the ‘ending form.' From a semiotics perspective each poet's ‘ending forms’ show his inclination towards certain ‘ending forms.’ The pattern as to how the ‘ending forms’ are employed and used can be deduced through examining the correlation between the frequency and the cognitive style in certain ‘ending forms,’ which create the overall image of the poem and the poet’s poetic world. In other words, it is not only the difference in content but also the semiotic differences employed in ‘ending forms’ that distinguish the poetic images of the two poets.

Palatalization and Vowel Fronting are the two notable features of modern Korean. Palatalization refers to the phonological phenomenon in which consonant sounds are changed by the vowel sounds. Vowel Fronting refers to the one in which vowel sounds are changed by the consonant sounds. It was believed that both phonological phenomena are the phonological assimilation phenomena caused by the feature of palatality. In this article, I will discuss the difference in the feature of palatality in both phenomena by raising a question that the palatality of both phonological phenomena result from assimilation. Palatalization occurs when the feature of palatality of /i, y/affects the preceeding consonants;it is an assimilation in which non-palatal consonants change into palatal consonants. The feature of vowel's [+high] change the feature of 'ㄷ, ㅌ' 's ?? to the feature of 'ㅈ, ㅊ' 's ??. Therefore, the palatality of palatalization is either ?? or ??. Vowel Fronting was believed to be a phenomenon in which a vowel is assimilated by a consonant. The argument is questionable for the following reasons. First, it is unnatural and execptional phenomenon. Second, /+ / is the only vowel among the vowels which is changed into /i /. Given the unique nature of the changes, this evaluation have to be reassessed. When both of these rules were examined in light of the Particle Phonology, Vowel Fronting is a process in which a most unmarked vowel is changing into a marked vowel-the addition of elementary particle [i] to the position of [+]. In other words, this means that the feature of palatality of Vowel Fronting is regarded as vowel strengthening. Furthermore, the feature of palatality can be explained as the strengthening phenomenon of /i/'s subjunction along with simple vowelization of dipthongs and umlaut.
