In this study, based on the System Dynamics (SD) methodology, the interrelationship between the factors inherent in the operation of the New Technology Certification System (NTCS) in Korea was identified by a causal map containing a feedback loop mechanism in connection with ‘new technology development investment’, ‘commercialization of new technology’, and ‘sales by new technology’. This conceptualized causal map was applied to the simulation of the operations of the New Excellent Technology and Environmental Technology Verification System (NET&ETV) run by the Ministry of Environment among various NTCSs in Korea. A SD computer simulation model was developed to analyze and predict the operational performance of the NET&ETV in terms of key performance indices such as ‘sales by new technology’. Using this model, we predicted the future operational status the NET&ETV and found a policy leverage that greatly influences the operation of the NET&ETV. Also the sensitivity of the key indicators to changes in the external variables in the model was analyzed to find policy leverage.
In this paper, a System Dynamics(SD) computer simulation model has been developed to assess the effects of developing and providing an alternate water source. A water service index was also developed to estimate the level of overall customer satisfaction on water supply service. Data from the Busan water supply service and the Korea Development Institute regarding the Nak Dong river bank storage development were utilized during the modeling processes. Some important indicators of the system under study were analyzed by the simulations of development of the alternate water source for Busan. The developed SD model and the water service index can be further utilized as a tool that can assess the extent and timing of an additional service improvement project.
Project CHILD constitutes a unique threedimensional instructional system that has been subjected to substantial evaluation and revision over the course of fifteen years and which has a proven track record of academic success for children in grades K-5. Project CHILD has continued to evolve and slowly expand across the United States. In the 2003-2004 school year there were over 14,000 students and more than 500 teachers involved. The system is based on an alternative, "retrotechno" theory of the proper role of computers in elementary education. The curriculum focus is on reading, writing, and mathematics, while the methodological focus is on team teaching, multiple instructional modes, and a three-year, continuous progress learning cycle. Effective school transformation is obstructed by three major barriers: school organizational structure, fear of losing control, and inappropriate training and staff development. Project CHILD has developed practical and effective ways to surmount these barriers.
Schools in developing countries such as China are faced with many challenges when it comes to K- 12 technology integration into classrooms and curricula. The Global Education Model School (GEMS) project aims to help schools overcome these challenges. In this paper we first examine the outcomes of the GEMS program in China, on the basis of which we propose a model for facilitating computer technology integration in K-12 schools China. It is the contribution of this new model to move the emphasis from support of teachers from the international and national levels to teacher collaboration at the school and regional levels. Through the use of technology, communities of teachers can be established, providing an enhanced and more sustainable change management process. The ultimate goal of such an improved change management strategy is to help expand technology integration in China's K-12 classrooms.
Effective integration of all manufacturing function is one of the best ways to achieve higher productivity, reduce the design, planning, manufacturing, and delivery time; and to improve the overall performance of a factory. Therefore, this paper describes the CIM architecture considering computer-aided process planning(CAPP) system, programmable logic controller(PLC) for on-line control, bar-code system for point of sales(POS) management, and automated storage/retrieval system(AS/RS) in manufacturing systems.
오늘날 많은 IT 관련 분야에서 컴퓨터 그래픽스 기술이 사용되고 있다. 더욱이 3D 프린터, Head Mount Display, VR & AR 등 컴퓨터 그래픽스와 밀접하게 관련된 분야에 대한 수요가 급증하고 있다. 앞으로 컴퓨터 그래픽스 분야는 더욱 전문화되고 이에 따른 인력의 수요도 증가할 것이다. 그러나 그래픽스 분야가 수학적 배경지식을 많이 요구하기 때문에 접근성이 낮고, 수요에 비해 이를 전공한 사람과 전문가의 숫자가 적다. 만약 그래픽스 프로그래밍을 쉽게 배울 수 있는 환경을 제공하다면, 컴퓨터 그래픽스 분야 인력 양성에 도움이 될 것이다. 따라서 이 논문에서 그래픽스 이론을 분석하여 초심자도 체계적이고 쉽게 배울 수 있는 교육용 소프트웨어 모델을 제시한다. 웹과 블록을 이용한 설계를 통해 접근성과 직관성을 높이고, 이론적인 내용을 중점적으로 학습할 수 있는 환경을 구축하는 방법을 제안한다.
Camera arrangement for depth and image correspondence is very important to the computer vision. Two conventional comera arrangements for stereo computer vision are lateral model and axial motion model. In this paper, using the axial motion stereo camera model, the algorithm for camera focal length measurement and the surface smoothness with the radiance-irradiance is proposed fro 3-dimensional image correspondence on stereo computer vision. By adapting the above algorithm, camera focal length can be measured precisely and the resolution of 3-dimensional image correspondence has been improved comparing to that of the axial motion model without the radiance-irradiance relation.
