  • This study was carried out to P University of Education 111 students who participated in science materials study course 1 in spring semester 2011. Students have taken the course pre-service teachers of elementary school classes to target elementary school earth science field, they selected one of the sections to create a class and the students have fulfilled 15-minute classes in respectively from the first week of May 2011 to until end of that course. In this class, colleagues evaluated the classes and we used evaluated scores to determine level of instructional motivation strategy. The obtained results from this study are as follows; First, motivational strategies used by preliminary elementary school teacher were questions, presentation of pictures and photographs, storytelling, presentation of contradictory concepts and phenomena, pilot experiments Second, among preliminary elementary teachers' motivational strategies for teaching in the field of the earth storytelling, presenting contradictory phenomena and concepts, pilot experiment, presentation of contradictory concepts, questions got higher scores in the order. Third, storytelling received the highest scores by the evaluators. So we can consider storytelling as a good strategy for the next class. In particular, storytelling used by animism were more effective. Fourth, preliminary elementary school teachers used life knowledges and dairy experiences as instructional motivation.

  • On the above, a comparison between preliminary draft conventions and comments by the Int'l Chamber of Commerce, contents of preliminary draft convention, problems and alternative are discussed. The conclusions are as follows thereof : The laws of MLEC and MLES made preparation for electronic era of CISG. But electronic circumstances are more changed than the time of regulation of them. Therefore the business world needs a stand-alone convention dealing broadly with the issues of contract formation in electronic commerce. At last, preliminary draft convention delivered a second round. But the base of the instrument was also MLEC and MLES. The revised preliminary draft convention is much amended beyond preliminary draft convention. At its forty-one sessions, the working group reviewed articles 1-11 of the revised preliminary draft convention presented by the secretariat. The remainder was pending until the time of its forty-two sessions. Therefore, on the base of deliberations and decisions of that sessions and them of thirty-six sessions of UNCITRAL, which will be held on comming november, the draft convention which will be prepared by the secretariate, be re-revised preliminary draft convention. According to review of working group on them, preliminary draft convention will officially be draft convention or revise by secretariate. Under these situations, my points of view on draft convention are as follows : As though e-UCP is used carring out side by side with UCP, after e-CISG making in order to adjust CISG to "on" transaction, it is very easy and prompt for business worked to use CISG with e-CISG. This will facilitate ratification of the CISG. For this case, I already presented contents of e-CISG. It is very important for the preliminary draft convention to deal specially with issues related to electronic contracting or to electronic transaction, because according to which way, its contents and scope of application will be different. But the revised draft convention is regretably compromising both them. Consequently, its contents are very confusing and we could not expect its success. If e-CISG will regulate, it is desirable that, if possible, working group has to make the general rule, and the making of useful, practical, affordable rule for electronic commerce, for example Uniform Customs and Practices for Electronic Commerce(e-UEC) in order to solve the specific practical problems, if any, which business currently faces regarding electronic contracting, has to entrust ICC. If working group want to make e-CISG, it is important not to hesitate and take a significant amount of time.

  • When the ground subsystem of Ground Based Augmentation System(GBAS) is installed at the airport, the functions and performance of subsystem should be evaluated through ground and flight testing at the pre-commissioning phase. In the case of GBAS flight testing, it can be conducted by the existing flight check aircraft, but the GBAS ground testing requires the development of specially customized equipment to perform the ground testing. Therefore, this paper describes the preliminary design of GBAS onboard test equipment which can be independently used for the GBAS ground testing and flight testing on a car and an aircraft.
