Comparing to the other subject, the relationship among physics contents is strong from the perspective of knowledge order as grades go up. That is, The things already that students learned, are learning and will learn are closed related from grade to grade. We expect students to be proactive and creative in studying physics, which is the goal of 21th century, analyzing their knowledge structure based on the knowledge order through assessment. Especially, using computer system, we provide students with substantial feedback for the assessment as well as objective validity is increased along with speedy and exact process in a bid to help students' mathematical understanding grow. This paper seeks to analyze the data from assessment applying knowledge spaces of the scientifical gifted in selective examination and to applicate on development of evaluation method.

In this paper, we propose a concpetual architecture and its implementation approach for contextualizing unstructured CCTV-video frame data into structured XML-video textual data by using the deep-learning neural network models and frameworks. Conclusively, through the conceptual architecture and the implementation approach proposed in this paper, we can eventually realize and implement the so-called sharable working and experiencing knowledge management platforms to be adopted to smart factories in various industries.

The purpose of this study is to investigate the young children's 'more means more' bias and knowledge change process regarding a lever phenomenon, especially the relationship between the weight of an object and the strength of force and between the length of a lever and the strength of force. Subjects, who were presented with the tasks, were eight young children 5 years of age. Major findings were as followings. First, most of the subjects have a 'more means more' bias about the relationship between the weight of an object and the strength of force and between the length of a lever and the strength of force regarding a lever phenomenon. This meant that young children have similar concepts about a lever phenomenon regardless of whether it is right or wrong physically. Second, young children tried to make sure of their knowledge during experiments. They chose the evidence which confirmed their knowledge. But they tried to change their knowledge, when the evidence presented did not correspond to their knowledge. These findings contribute to understanding young children's 'more means more' bias and knowledge change process about a lever phenomenon and can be used in preschool science education programs and curriculums.

Unlike existing other industries, the knowledge-based industry has the potential to grow increasingly with factor input unlimited. Importance of investigating knowledge and information evaluation cannot be overemphasized to promote economic development in that knowledge and information is accepted as an engine of new economy. We attempt to define the scope and value of knowledge and information and develop the knowledge and information value model. The results help policy-makers to manage and evaluate the knowledge and information with useful and responsible information.

금속재료의 성질은 상(phase)의 혼합된, 즉 금속학적인 지식으로 이해할 수 있는 부분과 상을 구성하고 있는 원자의 결합상태 혹은 전자의 존재상태를 생각하지 않으면 안되는 부분이 있다. 예를 들면 철과 동을 비교할 경우 동의 경우가 전기전도성이 좋은 이유라든가 대기중에 방치한 경우의 내식성이 좋은 이유, 또는 철이 강자성을 나타내는 이유 등 어느 것도 금속중의 전자의 거동에 의해서 설명하지 않으면 안된다. 그리고 원자로에 사용되는 재료로써 문제시되는 중 성자의 흡취능과 같은 것은 원자핵의 구조를 이해하는 입장에서 고찰하지 않으면 안된다. 이들의 분야는 어느 것이든 금속물리학의 중요한 분야이지만 여기에서는 취급하지 않고 다만 금속학적인 지식도 재료의 물리적, 화학적 성질을 이해하는 데에 있어서 중요하다는 것을 예를 들어 기술 하는 데에 그쳤다.

의료 정보 시스템은 많은 지식과 의료 인력과의 연계가 필요하기 때문에, 멀티 에이전트 시스템의 활용 영역으로 적합하다. 본 논문에서는 지능형 의료 정보 제공을 위한 멀티 에이전트 시스템인 MAMI(Multi-Agent system for Medical Image)의 에이전트 플랫폼의 설계 및 구현 대해 기술한다. MAMI는 여러 의료 정보 중 의료 영상을 위한 멀티 에이전트 시스템이다. MAMI의 가장 중요한 구성 요소로서는 에이전트 플랫폼을 들 수 있다. 에이전트 플랫폼은 에이전트들이 동작할 수 있는 물리적 기반을 제공해 준다. MAMI는 FIPA(foundation for Intelligent Physical Agent)가 제안하는 관리 모델을 따르고 있다. MAMI에서는 COM(Common Object Model)과 XML(Extensible Markup Language)로 인코딩된 ACL(Agent Communication Language)을 메시지 교환에 이용하고 있다. 의료 영역의 특성상 의사와 같은 의료 전문 인력과의 연계는 반드시 필요하다. MAMI는 이를 위해서 의료 인력을 하나의 에이전트로 개념화하여 시스템에 연결한다. MAMI의 에이전트 플랫폼은 소프트웨어 에이전트와 휴먼 에이전트들이 지식을 공유하기에 적합한 물리적 기반을 제 공해주어 지능형 의료 정보 서비스를 용이하게 해준다.

The purpose of this study is to review the expanded role of authority files, which uses the Knowledge Organization System(KOS) to organize contents and manage the collections in digital libraries. The KOS plays a role as a bridge between the users' information needs and materials by providing links between catalogs and digital resources on the web and supporting retrieval of the relevant items. It is described how a KOS can be used to link a digital resource to related materials, to provide more descriptive records for entities, and access to relevant physical objects.

In this paper, we propose a mechanism to transform more effective and semantically equivalent queries by using appropriately represented three kinds of knowledge. Also we proposed a mechanism which transforms partially omitted components or expressions into complete queries so that users can use more simple queries. The knowledges used to transform and optimize are semantic, structural and domain knowledge. Semantic knowledge includes semantic integrity constraints and domain integrity constraints. Structural knowledge represents physical relationship between relations. And domain knowledge maintains the domain information of attributes. The proposed system optimizes to more effective queries by eliminating/adding/replacing unnecessary or redundant restrictions/joins.

Visualization of the electromagnetic vector fields are presented and examined with Mathematica. Vector fields may be used to represent a great of many physical quantities in various area of physics, including electromagnetism with vector differential operators. Because they deal with abstract, three-dimensional fields that are some times very difficult to visualize, electromagnetism can be conceptually rather difficult. Visual representation of such an abstract vector fields is invaluable to student or researchers working in this field and also helps teaching electromagnetism to physics or engineering students. Mathematica provides a wider range of graphical tools including plot of vector fields and vector analysis, which can be applied to visualization of electromagnetic system. We have visualized the most fundamental concepts of the electromagnetic vector $\vec{E}=-\vec{\nabla}_{\varphi}$, $\vec{D}={\epsilon}\vec{E}$, $\vec{\nabla}{\times}\vec{A}$, $\vec{B}={\mu}\vec{H}$, $\vec{B}={\mu}_0(\vec{H}+\vec{M})$, which are confirmed with vector calculations and valid graphically with some presentations.

This study proposes a digital twin implementation method through simulation so that the manufacturing process can be optimized in a manual manufacturing site. The scope of the proposal is a knowledge management mechanism that collects manual motion with a sensor and optimizes the manufacturing process with repetitive experimental data for motion recognition. In order to achieve the research purpose, a simulation of the distribution site was conducted, and a plan to create an optimized digital twin was prepared by repeatedly experiencing the work simulation based on the basic knowledge expressed by the worker's experience. As a result of the experiment, it was found that it is possible to continuously improve the manufacturing process by transmitting the result of configuring the optimized resources to the physical system by generating the characteristics of the work space configuration and working step within a faster time with the simulation that creates the digital twin.
