  • With elementary school students who have learned the primary concepts of the four arithmetic operations as its subjects, this study has investigated in depth how schema and transformed schema are composed by recognition of the correct concepts and connection of concepts, that is to say, what schema learners form along with transformed schema with the primary concepts of the four arithmetic operations to understand the secondary concepts when power and mixed calculations are taken into contents. It has also investigated how the subjects use the schema they have formed for themselves and the transformed schema to approach problem solving, and how their composition of concepts and schema in problem solving ability achieve transformations. As a result, we can tell that the recognition of precise primary concepts and transformed schema work as important factors in the development from the primary to the secondary concepts. Here, we can also see learn that the formation of the schema created due to the connection among the primary concepts and the recognition of them and of the transformed schema play more important roles in the development toward the secondary concepts and the solution of arithmetic problems than any other factors.

  • On the subjects of elementary 3rd grade three child prodigies who had learned the four fundamental arithmetic operations and primary concepts of fraction, this study conducted a qualitative case research to examine how they composed schema of addition and multiplication of fractions and transformed schema through recognition of precise concepts and linking of concepts with addition and multiplication of fractions as the contents. That is to say, this study investigates what schema and transformed schema child prodigies form through composition of primary mathematic concepts to succeed in relational understanding of addition and multiplication of fractions, how they use their own formed schema and transformed schema for themselves to approach solutions to problems with addition and multiplication of fractions, and how the subjects' concept formation and schema in their problem solving competence proceed to carry out transformations. As a result, we can tell that precise recognition of primary concepts, schema, and transformed schema work as crucial factors when addition of fractions is associated with multiplication of fractions, and then that the schema and transformed schema that result from the connection among primary mathematic concepts and the precise recognition of the primary concepts play more important roles than any other factors in creative problem solving with respect to addition and multiplication of fractions.

  • 과학에서 사용하는 모델은 자연 그 자체가 아니면 자연을 단순화하여 표현한 표상이다. 그렇기 때문에 각 모델은 자연을 표상하기 위한 특정한 알고리즘을 갖는다. 그러므로 과학 모델에 대한 이해는 자연을 표상하기 위한 특정한 알고리즘이 무엇인지에 대한 이해가 필수적이다. 이러한 특정한 알고리즘에 대한 이해와 이를 바탕으로 한 다른 현상의 예측과 설명을 위한 도구로 본 논문은 스크래치를 활용하였다. 또한 과학의 모델에 대한 이해의 소재로 대학생뿐만 아니라 많은 과학교사 조차도 대안개념에 머물러 있는 뜨거나 가라앉는 현상을 선정하였다. 연구대상은 K대학원 교육대학원 멀티미디어와 과학교육을 수강한 17명의 과학교사이며, 스크래치를 통해 기본 알고리즘 3시간, 응용 알고리즘 3시간을 투입하였다. 모델에 대한 이해를 위해 뜨거나 가라 앉는 현상에 때한 LP설문지를 사전, 사후검사에 실시하였다. 1차적으로 양적변화를 통해 이 현상에 대한 개념의 수준의 변화를 알아보았으며, 2차적으로 인터뷰와 자기보고식 설문지를 이용하여 모델에 대한 이해를 질적으로 분석하였다. 연구결과 과학교사들은 현상에 대한 개념에 대한 수준이 상승하였으며, 질적자료 분석 결과, 모델에 대한 깊은 이해(depth)와 전이능력(transfer)이 증가하였다. 이는 스크래치를 통해 과학 모델의 이해를 높일 수 있음을 시사한다.

  • The 'hands-on' craftsmanship of the 20th century has came and gone. Today, we are dealing with whole new, 'cerebral approach,' to concept and design with this new approach, design and function are very much dependant upon planning, sales, promotion, and the formative technique of the design industry. The innovative process of design constantly change as it reflects the needs and wants of society. It is and industry that constantly change as it reflects the needs and wants of society. It is and industry that constantly remakes and reshapes itself to suit current trend and outlook. The current idea being that consumers are looking for quality over quantity. Due to the 20th centuries dominant philosophy of functionalism, production intended to standardize the individual's purchasing choice. Aesthetic, or philosophic qualities played a second fiddle to the functional bias of a product, With production, Marketing, and research and development are integrated into the management process. This translates as good which include efficiency, quality, durability, and credibility an trademark and style. There is a definite 'post-modernist' movement and style in 21st century. Every possibility is available as the old boundaries of the 20th century are laid aside. There is a new, transformative quality to the current paradigm of design. The old "should" and "should not" of design no longerapplies. The integrated rative of design solves the usual disparity between aesthetic qualities and production. Design and profirability need not be stranger to one another. It can differentiate the image perceived of both enterprises and consumers by making use of integrated goods services. With an integrated system. both producers and designers win. While design gets full access to design in turn. All consumers make decisions based upon the evaluation of quality, service, and image ; even though it may not be a conscious decision to do so. Consumers are fully integrated human beings ; therefore producers who apply the new, integrated paradigmatic approach to concept, design, and production will reap the harvest of making a true relationship with individual buyer.

  • 모든 공동주택에 적용되고 있는 기존의 피난시설은 고층부분에서 사용의 제한, 세대 간 보안 및 사용자의 제약 등으로 실제 현장에 적용하여 사용하는 되는 많은 문제점을 내포하고 있다. 또한, 이와 관련하여 공동주택의 용도 특성상 조기 피난이 이루어지지 못하는 경우가 빈번하여 화재 때문에 세대 내 출구가 폐쇄되고 재해약자가 사용하는데 어려우며, 화염과 복사열로부터 안전을 해결하기에는 현재 공동주택에서 보편적으로 설치되어있는 완강기로 이러한 문제를 해결하기에는 매우 미흡한 실정이다. 이에 본 연구에서는 이러한 문제점을 해결할 피난방법이 적용된 피난시설을 제안하고자 한다. "피난대피시설"은 공동주택 발코니 또는 외벽에 콤팩트(compact)하게 접혀 있다가 화재 시 수동 또는 감지기와 연동해 쉽게 작동되어 대피공간 용도와 유사시 자력으로 피난층까지 피난할 수 있는 구조이다. 또한, 화재실과 접하는 부분은 $1,200^{\circ}C$의 복사열을 차단할 수 있는 단열소재로 구성되며 1차적으로는 화재 장소에서 외부 공간으로 일탈한 후에 2차적으로 아래층으로 사다리를 이용하여 피난할 수 있게 되어 있다. 본 연구개발의 주안점은 화재 시화염과 복사열로부터 공간 일탈을 하여 재실자를 보호할 수 있는 대피공간의 개념과 피난시설에서 피난층으로 피난할 수 있는 적극적인 피난방법을 접목한 것이 피난시설 개발의 핵심이다.

  • The more income and free time people have, the more interest in cultural heritage they get to improve the quality of life. In light of this, Local governments put more effort to create colorful events using their cultural heritage resources, and the central government also starts to implement policies to enhance the value of cultural heritage. To keep those efforts on utilizing cultural heritage, however, several issues seem to be addressed in advance. Firstly, it needs to define the concept of cultural heritage utilization that could cover its current policy trend. Secondly, the utilization methodology should be categorized and classified. Therefore, the study for those issues should be carried out to utilize the cultural heritage efficiently and systematically. This study contains the current status of the relevant policies and projects; the trend and meaning of the utilization. And, in this study, the cultural heritage utilization was defined as all activities producing positive effects or influences by cultural heritage such as enjoying cultural heritage values and creating additional profits. Furthermore, the cultural heritage utilization was categorized according to several criteria; the value, the objective, and the type of cultural heritage utilization. Finally, the final part of the study includes proposals on the future policy direction of cultural heritage utilization.
