The COM curriculum provides first a core of mathematics for all students, and then offers opportunities for students to enter different streams of mathematics studies. The flexible curriculum (COM) is certainly welcome as it focuses on a transition from concrete to conceptual mathematics and on sequentially learning the power of mathematical language and symbols from simple to complex. This approach emphasizes the use of computers in mathematics education in the upper secondary grades. In Mathematics A, one unit is developed to computer operation, flow charts and programming, and computation using the computer. In mathematics B, a chapter addresses algorithms and the computer where students learn the functions of computers, as well as programs of various algorithms. Mathematics C allots a chapter for numerical computation in which approximating solutions for equations, numerical integration, mensuration by parts, and approximation of integrals. But, unfortunately, they do not have any plan for the cooperation study.

To solve modern social problems, it is important that improve the democratic citizenship quality of people. This quality includes the rational and democratic problem-solving capacity, decision-making capacity, democratic skills and attitudes such as human dignity, dialogue, compromise. To use an educational network simulation game that has the merits of game, simulatio and network will help children to improve the democratic citizenship educaiton. This study explorers the structure, flow, system, database, interface and teaching-learning tool for this educational network simulation game.

Teachers' beliefs about teaching English are reflected in their practices in the classroom. They influence on the students' attitude to English learning. Any teacher training program expects the trainees to change or modify their existing beliefs and attitude through the new ideas and information introduced by the program toward a desired direction. The present study describes a teacher training program for elementary school English teachers and compares the beliefs of the teachers about teaching English before and after the training. The subjects are the elementary school English teachers around Chungnam area who get a special training of 120 hours during January 1997. The investigation of the subjects' beliefs on English teaching is conducted through examining two journals of each subject before and after the training. The journals show the teachers' inner flow of thought, so teacher trainers are expected to get insight on their general instructional considerations and have implications on the future teacher training program through examining these journals. In addition, the journal writing itself gives the teachers opportunity to reflect their practice and rethink about their beliefs, and develop themselves as professional English teachers.

Digitalization of not only non-safety but also safety-grade I &C systems with full computerized Main Control Room (MCR) is the recent trend of I&C systems of nuclear power plants (NPP) around the world, while plant maintenance has been shifting from traditional time based maintenance to condition based maintenance. In order to cope with the new trend of operation and maintenance in NPP, a concept of online distributed diagnostic system for both plant operation and maintenance has been proposed in order to further improve both the plant efficiency and the work environment of plant operation staff members by organizational learning. In this respect, the research subjects of human machine interface (HMI) for the online distributed diagnostic system are also discussed for supporting the plant personnel at both MCR and local working places in the plant by the application of advanced ICT (Information and Communication Technologies).

This paper presents a beat gesture recognition method to synchronize the tempo of a robot playing a piano with the desired tempo of the user. To detect an unstructured beat gesture expressed by any part of a body, we apply an optical flow method, and obtain the trajectories of the center of gravity and normalized central moments of moving objects in images. The period of a beat gesture is estimated from the results of the fast Fourier transform. In addition, we also apply a motion control method by which robotic fingers are trained to follow a set of trajectories, Since the ability to track the trajectories influences the sound a piano generates, we adopt an iterative learning control method to reduce the tracking error.

This paper presents a Web-based educational tool for Power System Engineering, especially for power engineers. This tool has Web-oriented educational courses for power system education. The Web-based learning has become more popular year by year in the various fields[1-2]. The proposed educational tool provides some courses such as power system introduction Course, KEPCO's system introduction Course, Power system devices Course, Power Flow Course, OPF Course, ELD Course, Stability Analysis Course, Fault analysis Course, Voltage & Frequency control Course, and power system planning & operation Course. Finally, it will be scheduled to install for the education tool of the power system engineering for KEPS[3].

We studied a CAI courseware model for distance education on network, with the use of Java language. Basic www files, contents of courseware, are constructed with html. Students and educator can access the preferred unit composed of the appropriate multimedia data by using of www browser at any time. The distance education system, in this paper, has functions to manage the flow of distance learning, and to offer interaction between students and system in distributed environment. Students and/or 'educator can discuss a topic through server in different places. We implemented these functions, which are required in server and client environment of distance education, with the use of Java.

본 연구의 목적은 스크래치를 활용한 프로그래밍 교육이 학생들의 몰입 수준에 미치는 영향에 관해 연구하는 데 있다. 본 연구는 초등학교 6학년 학생들을 대상으로 정보통신이해 영역 중 '프로그래밍의 기초' 에 관한 학습 내용을 중심으로 스크래치로 학습하고 실험집단과 통제집단을 선정하여 사전사후 검사를 실시하였다. 연구 결과, 스크래치를 활용한 프로그래밍 교육 후에 몰입 수준이 높아짐을 확인할 수 있었다. 몰입 수준의 향상은 학업성취도에 긍정적인 영향을 미치는 것으로 초등학생을 대상으로 스크래치를 활용한 프로그래밍 교육활동이 프로그래밍 성취도에도 영향을 미칠 수 있을 것이라 기대된다.

2014년 가트너에서 발표한 Hype Cyle을 보면 가상세계 기술이 가상현실 기술로 빠르게 대체 되고 있다. 이는 눈으로 보는 가상세계에서 사용자가 실제적으로 체험할 수 있는 콘텐츠들이 중요하게 부각되고 있음을 보여주고 있다. 이러한 가상현실 기술은 사용자와 컴퓨터가 상호작용 함으로써 사용자의 몰입감을 더욱 높여주고 있어 다양한 분야에서 활용될 것으로 기대되고 있다. 이에 본 논문은 세종대왕시대에 만들어진 유물들 HMD(Head Mounted Display)를 이용하여 가상현실 콘텐츠를 개발하였다. HMD를 통해 사용자의 시야와 가상공간의 움직임을 일치시켜 역사 유물들에 대해 실제감과 몰입감을 주어 사용자에게 즐거움을 극대화 할 수 있게 하였다.

This paper proposed a optimal scale factors technique of a fuzzy-neural network for a load frequency control of two areas power system. The optimal scale factors control technique is optimize from an initial fuzzy logic control rule, and then is learned with an error back propagation learning algorithm of the fuzzy-neural network. In application two areas the load frequency control of the power system, it hopes to have response characteristic better than optimal control technique which is the conventional control technique and to show to minimize a frequency deviation and reaching and settling time of a tie line power flow deviation
