본 연구에서는 나눗셈의 도입시 이용되는 두 가지 의미인 포함제와 등분제에 대한 초등학생 및 예비초등교사의 이해에 대해 조사하였다. 역대 교육과정 및 그에 따른 교과서에서 나눗셈을 도입하는 상황으로 양자를 다루어왔지만 그 구별을 어느 정도로 명시적으로 다루었는가 하는 것은 시기에 따라 변화되어 왔다. 특히 현행 2007년 개정교육과정에 따른 교과서에서는 두 가지 의미에 따라 나눗셈을 별도로 정의하고 몫의 의미에 대해서도 명시적인 언어적 설명을 추가하는 등 이전과 다른 특징을 보여준다. 계산 기능뿐만 아니라 연산의 의미 이해를 강조하는 수학교육 경향의 한 단면으로 간주되는 이러한 의도가 학생들에게 얼마만큼 수용되고 있는지 알아보기 위해 초등학교 3학년 학생을 대상으로 질문지를 적용하여 그 결과를 분석하고, 또한 두 상황의 명시적인 구별 가능성을 타진하기 위한 기초 자료로서 예비초등교사의 이해도를 조사하였다. 결과적으로 현행 교과서의 접근 방식에 대한 재고의 필요성을 확인하고, 나눗셈의 지도를 위한 몇 가지 교수학적 시사점을 도출하였다.

나눗셈의 의미는 수의 범위가 확장되어도 연결된다. 즉, 자연수 범위에 적용되는 나눗셈의 의미는 분수 및 소수를 다루는 유리수 범위로 확장되어도 적용가능하다. 이러한 측면에서 자연수의 나눗셈과 분수의 나눗셈, 소수의 나눗셈을 서로 연결하여 가르치는 것은 수학의 내적 연결성을 통하여 나눗셈을 의미 있게 학습하는데 도움이 될 것이다. 본 연구에서는 5학년 2학기에 제시되는 분수의 나눗셈과 소수의 나눗셈 단원을 나눗셈의 의미와 절차가 연결되도록 재구성한 뒤 수업을 실행하고 분석하였다. 연구 결과, 학생들은 수의 범위가 확장되더라도 나눗셈의 의미를 이해하여 문제를 해결하거나 만들 수 있었다. 또한 문제 해결 과정에서 자연수의 나눗셈, 분수의 나눗셈, 소수의 나눗셈의 원리를 이용할 수 있었다. 단, 일부 학생들의 경우 나눗셈 의미를 이해하지 못하여 잘못된 나눗셈식을 세우거나 문제를 만들었으며, 특정한 해결 절차만을 선호하는 모습도 발견할 수 있었다. 본 연구를 통하여 초등학교 전 과정에 제시되는 나눗셈을 연결성을 강조하여 의미 있게 지도 학습할 수 있는 방향을 모색하는데 도움이 되기를 기대한다.

본 논문은 기본적인 계산능력이 뛰어난 초등학교 6학년 학생 2명을 대상으로 분수 나눗셈 문제를 해결하는 과정에서 나타나는 연산 감각을 분석하였다. 구체적으로 학생들이 분수 나눗셈의 다양한 의미와 모델을 어떻게 이해하고 있는지, 분수 나눗셈 알고리듬의 의미를 어떻게 이해하고 있는지, 그리고 이러한 연산의 의미와 성질을 어떻게 응용하는지에 대해 임상 면담을 통해 면밀하게 탐색하였다. 구체적인 에피소드를 바탕으로 연산감각의 구성요소별로 두 학생의 질적 차이를 분석하고, 이를 기초로 하여 초등학교 고학년에서 연산 감각 자체를 보다 집중적으로 조명해 볼 필요가 있다는 점을 강조하였다.

Bulguk Temple, one of the national temples, sublimated the high formalism and symbolism into lovely art, and thus be called the pinnacle of Korean architecture. Of many characteristic structures of Bulguk Temple, the stone stereobate and stairs have a great importance in that we can read out the purpose of the architect through their relics. Especially, the stone stairs are noteworthy for they structuralize the intentional space division. The objects of this observation are Yeonwhagyo and Chilbogyo bridges at the entrance of Keungnakjeon precinct, and Cheongwoongyo and Baekwoongyo stairs at the entrance of Daewoongjun precinct. All these relics are the structures that divide the precinct areas on the basis of Buddhist theory and have strong symbolic meanings as well. Although the diverse studies have made on the structures, there are many insufficient aspects for the manifestation of the meanings. In this study, I considered the Buddhist dogmatic meanings of the structures in the formalistic view of the Buddhist architecture. The study was proceeded in the way that the establishments of former studies were fully reflected in it. Through the study, I could confirm that the objects of consideration have the double formalistic meanings and they are strongly structuralizing the symbolism.

The purpose of this study is to investigate the symbolic meaning of pattern designs attached on the main building of Chungcheongnam-do Provincial Government (CPG). While most of researches mainly focused on the value and evaulation of the CPG building in terms of architectural history, relatively little insight has been gained on the symbolic meaning and mature of the pattern designs. What king of connections are related between the emblem of Governor-General of Chosun(Korea) and those of CPG? What symbolic meanings are engraved on the pattern designs? The researcher then took up the task of elucidating symbolic meanings of patterns and their relation to the building. The existing pattern of the outer wall of the CPG building consists of the symbol of sun(太陽輪), mums(菊花輪), and angle of stairs(雁大角). According to the Japanese Studies of emblems, these visual elements symbolize 'the sun of Japan'((日の丸) or 'the emperor', 'the royal family', and 'rays of the sun'. Based on these preliminary findings, the researcher considered the following in-depth connections: (1) relations with the emblem of Governor-General of Chosun, (2) relations with the emblems of local autonomous entity, Kyoungsung in Chosun. (3) relations with the emblem designs of the local provinces in Japan etc. In conclusion, patterns of the main building were not just an architectural decoration, but they had significant meanings utilizing design elements and methods adopted by local autonomous entities in Japan, The patterns found at the ceilling and floor of hall in the CPG building were associated with the emblem of Governor-General of Chosun. Therefore, all the patterns of the CPG building are powerful symbols that have meanings for the colonial rule by using the shape and method of city identities that Japanese local provinces had enacted. That is, it came out into the open that they were designed for special meanings that Korean and Japanese are united as a single body(內鮮一體) for a subject of the Emperor of Japan(皇國臣民).

Icon conveys symbolic information which they have become ubiquitous as main element of GUI. However, users often cannot intuitively understand its functional meanings. Icon has to be designed for users to easily understand functional meanings. In order to evaluate icon, the spreading activation model can be used to effectively understand the process of information retrieval. In asymmetric spreading activation model is that in the two nodes the degree of spreading activation is different according to direction. Thus, asymmetric spreading activation theory was performed evaluating the strength of association when users see visual image to associate their verbal meaning (visual image - verbal meaning pair) and users see verbal meaning to associate their visual image (verbal meaning - visual image pair). According to the direction, this study hypothesizes that the well-designed icons have symmetric relationship rather than asymmetric relationship between the two pairs. The strength of association is measured through the reaction time and the accuracy rate. In performing SAT (spreading activation test), the ten icons were selected as word processing software icons. After first SAT, newly designed icons were developed based on Korean mental model, and second SAT was conducted using them. The results showed that the accuracy rate of newly designed icon has been improved. Also there is significant difference of reaction time between current icons and newly designed icons. Well-designed icon is confirmed that the strength of association relationship arises symmetrically rather than asymmetrically between the two pairs. User centered icons could be designed by improving the strength of association between the two pairs. Asymmetric SAT evaluates the strength of the association between the visual image and the verbal meanings to contribute to the development of icon which it related to human's association structure.

Objective : The using of termionology in medicine is important because terminology discriminates the meaning of words. In that aspect, there are conflicts that bao has plenty of meanings as medical terminology(womb and urinary bladder). Therefor, we need to discriminate and define bao. Method : We compare terminology of bao and words related with bao such as pao(胞) in "Dongeuibogam", "Hwangdineijing" and medical dictionary. Also we try to define right meaning of words as medical terminology. Result : Bao has several meanings in medical books. However, they have tendencies that could make scholars choose appropriate terminology in medicine. Conclusion : Bao is preferred as a womb and pao is prefferd as a urinary bladder in medical terminology.

The area of discourse analysis has long neglected the value of images as a semiotic resource in communication. This paper suggests that like language, images are rich in meaning potential and are governed by visual grammar structures which can be utilized to decode the meanings of images. Employing a theoretical framework in visual communication, two digital images are examined for their representational and interactive dimensions and the dimensions' relation to the magazine advertisement genre. The results show that the framework identified narrative and conceptual processes, relations between participants and viewers, and symbolic attributes of the images, which all contribute to the sociological interpretations of the images. The identities and relationships between viewers and participants suggested in the images signify desirable qualities that may be associated to the product of the advertiser. The findings support the theory of visual grammar and highlight the potential of images to convey multi-layered meanings.

The purposes of the article are to explore historical contexts where everyday life is identified as the essence of family studies, and to suggest qualitative methodology which is effective to understand meanings of family everyday life. Everyday life is the integrity of the time when family members progress in a family life cycle, the space where they interact with each other, and the way how they achieve their developmental tasks. Qualitative methodology, coming from interpretive science paradigm, focuses on those processes, interactions, and meanings of family members in natural settings. Example researches are introduced to show what specific topic can be studied and how they be interpreted for exploring family everyday life. The future of studying everyday life is discussed in terms of the research topic and the methods.
