  • This paper reviews a finite element model of a wire rope isolator (WRI) via an experimental comparison test. A local operation panel (LOP) mounted on a WRI is modeled using a finite element method. Mode analyses and harmonic analyses are conducted while varying of the thickness of the rope for the WRI. A feasible WRI can be selected considering the reduction of the vibration and the total weight of the LOP system.

  • 환경시료들은 매트릭스의 조성이 매우 복잡하여 공존하는 성분들이 목적성분의 검출에 영향을 미치므로 분리하는 조작이 필요하다. 환경 중에 존재하는 물질들은 동적인 평형상태를 유지하고 있기 때문에 시료를 채취하여 실험실로 운반하여 보관하는 동안에 분석 대상 물질이 용기에 흡착, 휘발 및 화학 반응의 진행 등으로 인하여 시료의 손실 및 변질을 초래 할 수 있다.(중략)

  • In this paper, Proposed the robust controller for robot manipulator plus actuator with dynamic parameter uncertainties. In general, errors and uncertainties system parameters exist more or less between the actual system and mathematical model. To reduce these trems, used Lyapunov stability theorem. The performance of the controller is evaluated for the three degree of freedom robot manipulator plus actuator model with uncertainties of parameters and model errors.

  • 전통적으로 기존의 제품은 정적인 환경에서의 학습과 언어적인지가 주요시되며, 제품 조작 시에도 커뮤니케이션의 많은 부분을 시각적 인터페이스에 주로 의존한다. 그러나 운전시 동적인 환경에서의 제품 Interface는 기존의 사용성 평가와는 달리 운전시의 동적인 상황을 많은 부분에서 고려되어야 한다. (중략)

  • 일반적으로 DBMS를 통해 데이터를 조회할 경우 C++이나 델파이와 같은 별도의 클라이언트 프로그램이 필요하고, 이종의 운영체제에서 작동될 경우나 클라이언트 수가 많을 경우에 운영체제에 따라 특정 클라이언트를 일일이 개발해야 할뿐만 아니라 별도의 클라이언트 모듈을 설치해야 하는 단점이 있다. 이러한 상황에서 웹 환경하의 웹 브라우저를 이용하면 웹 서버에 데이터베이스를 조작하는 프로그램만 설치함으로써, 클라이언트에 별도의 작업을 가하지 않고 데이터를 조회할 수 있다. 본 논문에서는 웹과 데이터베이스를 연동방법중 Stored Procedure 어플리케이션 로직구현 방식을 이용하여 학사관리 시스템 중 성적관리와 수강관리 어플리케이션을 분석, 설계, 구현하였다. 웹과 데이터 베이스를 연동하여 사용할 때 발생할 수 있는, 스테이트의 단절은 사용자의 요구가 있을 경우 동적 데이터 베이스를 만들어 주미가 될 수 있는 데이터를 입력시켜다른 웹 DB 어플리케이션들이 작동할 때 마다 읽어들이게 함으로써 해결하였다.

  • This papr studies the dynamic effects of polyelectrolyte in the multilayered membrane. It is found that electrophoretic convection in the fluid phase can be used to accelerate the speed of the polyelectrolyte. The model in the membrane separation is studied via interactions between fluid and solid phases. The spectra evaluation using the operator theoretic method is performed for the parametric studies of the physical properties in the membrane process. The findings of this paper shoould be useful in guiding the design of separation devices. This paper shows one example for macroscopic study the theoretical review paper of membrane transport.

  • Students develop mathematical concepts through concrete operations in the area of mathematics. However, most of the learning contents provided on the web are not interactive and limit interactions with learners. To overcome the limitations, there have been needs to develop learning contents to support active interactions with students according to their cognitive levels. In this study, the curriculum of numbers and number operations in elementary mathematics was analyzed. Based on the object-oriented design principle, "Number Classes" on numbers and number operations were designed and implemented. A class-based learning applet was developed with theses "Number Classes". It was developed in small unit programs based on learning themes of mathematics in elementary schools. With this learning applet, the active explorations through easy operations will help students to learn concepts and principles of numbers and number operations. It will strengthen active interactions of students with computer.

  • Time series data is a sequence of data points, measured typically at successive, spaced at time intervals. Many devices for an efficient exploration is developed according as the items of time series data increase. Among these devices, there is a Timebox widget as a representative device of dynamic query for interactive data exploration. Timeboxes are rectangular query region of interest. The users can draw the region of interest using simple mouse manipulation and the query result sets is displayed. But there is a limitation to represent the concrete query region and Timeboxes visualize the query region inconsistent with the mental model of users. To resolve these problems, we propose a new device called DQB(Dynamic Query Band). DQB is a qeury region consisting of user defined polyline with a thickness on time series data. This device is possible to concretely specify the query region. Also, it provides a simple and convenient interface and a good conceptual model.

  • One of the main objects of geometry in mathematics education is to improve students' geometric intuition capability and logical reasoning capability based on them. A visual element related to intuition plays an important role in teaching and learning of geometry. Therefore, in this research, we focus on the development of multimedia title available to dynamic operation about visual elements and verify of effect of its application. This title for the learning of "the Pythagorean theorem and its practical use" in the third grade of middle school is designed and implemented by an authoring tool, Toolbook. And it enables learners to study mathematics individually and can be applied to the educational field, too. And we taught two groups, the applied group and the compared one of the second grade of middle school and surveyed Questions and evaluated study achievement. We calculated study achievement of two groups on t-test using SPSS. As the result, we knew that the applied group is higher than the compared one in the study achievement and provision of dynamic operation possibility on visual elements make students know very high learning effect and help improvement of intelligent capability.
