The purpose of this study is to investigate student's Acquisition about the conception of the Earth Rotation between difference of their Spatial Sensibility. In this study, four students were selected out of 83 9th graders in Gwangju, Korea. The spatial sensibility test instrument was developed by the Korean Testing Center, and the test instruments of 'the movement of celestial bodies' were developed by Kim (1997). The results were as follows: Students with higher spatial sensibility understood precisely about the Earth's rotation in stereoscopic space. However, those with lower spatial sensibility failed to grasp the Earth's rotation and memorized it as fragmentary concepts. As for gender effect, male student with higher spatial sensibility explained the concepts clearly, while that with lower spatial sensibility has difficulty with the Earth's rotation in relation to the diurnal motion of celestial bodies. On the other hand, female student with higher spatial sensibility explained the concepts correctly in detail, while that with lower spatial sensibility had difficulty explaining the concepts in stereoscopic space. Therefore, students with higher spatial sensibility should be presented with problems in which they form their own solution. Those with lower spatial sensibility should be allowed to understand the phenomena intuitively. In developing teaching methods, female students should interact with the concepts in stereoscopic space directly, while male students should consider the celestial objects from various viewpoints. Then spatial sensibility in relation to the movement of celestial bodies would be expected to improve.

This study has the purpose to make a conceptual model which can explain the relationship between the research performance, and the fitness of environmental property and the technology development strategy. The environmental property consists of the competitiveness, the complexity of environment, and the market growth. The technology development strategy consists of the innovativeness of technology, the upgrade of product, and the usage of the out resource. And the ability to manage knowledge resource is a very important variable which can modulate the fitness of environmental property and the technology development strategy.

User interlace comes out from the combination of various school systems. It may be a strong point but could be a weak point, as the characteristics and peculiarity of specific school system cannot be well reflected. Therefore, the study aims to find the oughtness of developing the user interface system on which the characteristics and peculiarity of design area are reflected, and to find the necessary features and viewpoint in development. To make this, this study examines the relationship of human and target, and technical form and meaning of the relationship regarding the user interface, and analyzes the similarity and difference through the design comparison. In addition, this study looks the background for the introduction of user interface in design area and analyzes the cause to study the relationship between the design and user interface. Consequently, the concept and system of the user interface can be included in the broad sense of design, but has not been developed into the appropriate system for the characteristics of design. Therefore, it is necessary to develop the concept, method and knowledge considering the characteristics of design upon concept interpretation and development process.

최근 국제적으로 물관리의 차세대 개념으로서 지능형 물관리(Smart Water Grid)가 활발하게 논의되고 있다. 우리나라에서도 일부 학자들을 중심으로 이에 대한 개념이 도입되고 있다. 현재까지 정리된 지능형 물관리의 개념은 최근 급성장한 정보통신기술을 활용하여 기존에 비효율적으로 운영되는 물관리의 시스템을 획기적으로 개선하자는 것이다. 따라서 이론적으로는 물의 생산, 정수, 배송 그리고 이용과 처리에 이르는 전 과정을 실시간으로 통합하여 관리하는 것이 가능하다. 국제적으로는 IBM과 Siemens 등과 같이 정보통신과 물산업을 선도하는 기업 주도의 기술개발이 진행되는 단계이다. 2000년대 초반에는 용수수급의 효율화를 위한 장치개발에 주력하였으나, 현재에는 용수수급과 관련된 제반사항에 대한 기술적 통합시스템 구축으로 적용범위를 넓히고 있다. 우리나라에서도 도시인프라 자료의 통합관리와 수질 모니터링 시스템 구축이 추진되었으며, 2010년 12월 발표된 새만금종합개발계획에서는 본격적으로 활용을 검토하고 있다. 그러나 지능형 물관리의 기술적 통합시스템 전략은 곧 심각한 제도적 장벽에 직면할 것이다. 아무리 우수한 기술적 시스템이 개발된다고 하여도 제도적 기반의 구축이 없으면 국민경제에 도움이 되는 현실적용에는 한계가 있다. 기존에 확립된 물관리의 제도적 기반으로는 한정된 지역의 좁은 영역에서 활용될 수밖에 없다. 이것은 우리나라의 물관리가 기본적으로 법적, 제도적, 행정적 차원에서 분리되어 운영되고 있기 때문이다. 본 연구는 지능형 물관리가 지향하는 기술적인 통합시스템 구축이 당면할 제도적 한계를 도출하고 이를 극복하기 위한 정책적 방향을 제시하고자 한다. 또한 2009년 국회에 제출된 물관리기본법(안)에 지능형 물관리의 개념을 도입하는 방안을 모색하고자 한다.

In the early days, the use of concept maps in mathematics education focused on how to represent mathematical ideas in the concept map. In recent years, however, concept maps have proved beneficial for improving problem solving ability. Conceptual diagrams can be used for collaboration among students, tools for exploring problems, tools for introducing problem structures, tools for developing and systematizing knowledge systems. In this study, we focused on the structure analysis of mathematical problems using Concept Map based on the analysis of previous research. In addition, we have devised a method of using concept maps for problem analysis and a method of analysis of systematic mathematical problem structure. The method developed in this study was found to have significant value by applying to the university scholastic ability test.

The Ontology is the concept of human beings in any sense to classify things as departure from the classification based on the meaning at the prensent situation and concepts as the object of the Ontology. also, the technology is shared the conceptualization in a formal ontology as a meaning to give a clear description to the conceptual engineering in the ontology. Specialized multimedia broadcasting of TV-Anytime standard and multimedia representation of the overall standard of the MPEG-7 based on the concept of broadcasting multimedia presentations that can be used to develop an ontology who is required. In this paper, in TV-Anytime and MPEG-7 multimedia standard for broadcasting multimedia contents based on standards developed for the ontology, an ontology language for expressing OWL (Web Ontology Language) and RDF (Resource Description Framework) and the broadcast contents using To represent metadata of the system who has been developed.

Numbers of research on ontology construction and its application are being done for knowledge and information processing using computers. But, the current ontology development methods and ontology construction tools are using in restricted field on propose. Therefore, proper ontology development processes and ontology construction tools on ontology characteristic are needed. In this paper, we propose ontology construction process(OntoProcess) that non-experts in specific field are able to construct ontology through conceptualization of knowledge and formalization of concepts from language resource. Beside, some problems may be occurred while numbers of people are working together to construct ontology: i)duplicated concept definition in conceptualization process of knowledge and ii)decreasing efficiency of ontology construction by short understanding about formal language and tool operation in formalization process. To solve the problems, we propose an ontology construction process for multiple developers (OntoProcess) using meta ontology. We develop an ontology construction system(OntoCS) based on proposed processes, and we show the efficiency of proposed processes and system from ontology construction experiment.
