Guidance Generation for Facilitating Meta-Cognitive Learning through Presentation Task
Hiroshi Maeno,Kazuhisa Seta 한국멀티미디어학회 2009 한국멀티미디어학회 국제학술대회 Vol.2009 No.-
It is quite important to build an HCI scheme that can encourage humans' intellectual activities. Needless to say, learning activity is one of the most intellectual one. In this paper, we'll discuss computer assisted learning for facilitating meta-cognitive learning as an example of such a promising HCI scheme. Meta-cognition plays an important role in acquiring and transferring expertise. Although we recognize the necessity of building a learning scheme for developing meta-cognitive skills, little knowledge for it has been acquired because it is difficult for learners and instructors to discuss meta-cognitive skills as learning topics: the knowledge for performing meta-cognitive skills is tacit, latent, and context-dependent. Our goal is to build a new learning scheme to support meta-cognitive learning. In this paper, firstly, we describe an overview of our learning support system. Secondly, we illustrate learning strategies in learning software design patterns, and then, propose the function of generating guidance information to facilitate acquiring such meta-cognitive learning strategies.
Development of a Master-Slave System for Active Endoscope Using a Multi-DOF Ultrasonic Motor
Takemura, Kenjiro,Harada, Dai,Maeno, Takashi Institute of Control 2002 Transaction on control, automation and systems eng Vol.4 No.1
Endoscopes for industrial and medical fields are expected to have multi degree-of-freedom (DOF) motions. A multi-DOF ultrasonic motor we developed consists of a spherical rotor and a bar-shaped stator, and the rotor rotates around three perpendicular axes using three natural vibration modes of the stator. In this study, a multi-DOF unilateral master-slave system for active endoscope using the multi-DOF ultrasonic motor is developed. The configurations of master and slave arms for active endoscope are similar, so that an operator can easily handle the master-slave system. First, driving characteristics of the multi-DOF ultrasonic motor are measured in order to design the slave arm and its controller. Next, the master arm and the slave arm are designed. Then, the unilateral feedback controller for the master-slave system is developed. Finally, the motion control tests of rotor are conducted. As a result, the possibility of the endoscope is confirmed.
STUDY ON MECHANICAL CHARACTERISTIC OF INCINERATION RESIDUE OF MSW FOR ITS EFFECTIVE UTILIZATION
( T. Hirata ),( Y. Maeno ) 한국폐기물자원순환학회 2002 APLAS Vol.2002 No.1
In Japan, the amount of the waste dumped in final disposal sites is increasing rapidly and developing a new final disposal site is very hard nowadays. Therefore, the lifespan of the final disposal sites appropriate for waste is decreasing progressively. Then, one of the important issues is how to decrease the amount of waste to be dumped in the final disposal site. For the purpose of decreasing the amount of waste, the authors have been considering the possibility of effective utilization of waste. Particularly, about 80 % of municipal solid waste (MSW) is burned at the incineration plants, then a large amount of incineration residue is produced in Japan. So, how to reduce the volume of incineration residue to be dumped in the final disposal site is an important issue, too. Therefore, the authors have studied the incineration residue in order to develop its new utilization. For it, it is necessary to clarify not only the chemical but also mechanical properties of incineration residue. The authors tried to carry out some geo-mechanical tests. In this paper, the authors mainly report these test results.

일본에서 매립지에 버려지는 대량의 폐기물은 급속히 증가하며 현재 새로운 최종처분은 전무하다. 그러므로 폐기물의 적당한 매립지의 수명은 점점더 감소하고 있고 매립지에 버려지는 대량의 폐기물을 감소할수 있는 방법이 중요한 이슈중 하나이다. 대량의 폐기물 감소의 목적으로 폐기물의 효과적 이용 가능성에 대해 토의한다. 특히, 도시 고형 폐기물(MSW)의 약80%는 소각장에서 소각하고 대량의 소각재가 발생한다. 그래서, 매립지에 버려지는 소각재의 부피를 감소하는 방법또한 중요한 이슈이다. 그러므로 소각재를 새롭게 이용하는 연구를 하며, 화학적이 아니라 소각재의 역학특성을 밝히는 것이 필요하다. 몇몇의 토양역학 실험을 실행하였고, 이 논문에서는 주로 이러한 실험결과에 대해 논한다.
