Expansion of a static analysis-based out-of-plane maximum inelastic seismic response estimation method for steel arch bridges to in-plane response estimation

We have previously proposed a static analysis-based method for estimating the maximum out-of-plane inelastic seismic response of upper-deck steel arch bridges. The method is developed on the basis of the numerical examinations of 6 upper-deck steel arch bridge models. It employs free vibration analysis, response spectrum method and equal energy assumption for the estimation of maximum out-of-plane response. Correction functions are proposed to modify the estimates by the equal energy assumption. In the current study, applicability of the same procedure to the estimation of maximum in-plane response is discussed. It is found that the method can be used also for the maximum in-plane response estimation by only modifying the pushover analysis procedure. The validity of the method is demonstrated for the same parametric models through further numerical evaluations

The Effects of Instructional Video in Distance Learning in Junior High Schools in Peru

この報告は平成12年度～14年度科学研究補助金基盤研究(B) 2 (課題番号12571042、研究代表者:赤堀正宜・桐蔭横浜大学)として実施した「ペルー遠隔中学校におけるテレビの教育効果研究」の主として宇佐美昇三担当部分である。これまで、科研費報告書(平成15年3月)をはじめ、日本教育メディア学会、日本映像学会で、各年次の調査結果を明らかにしたが、これだけをまとめたものはない。さいわい2003年9月4～7日、韓国ソウルで開かれたKAEIB(韓国教育情報・放送研究学会)と日本教育メディア学会の合同研究会で、口頭発表する機会を得たので、新資料を加えて、ここに新たに書き下ろした。ペルー現地での調査備忘録(邦文)を付し、今後、同様の調査される方のご参考とする。This paper outlines a pilot study of Peruvian distance learning in junior high schools (hereafter referred to as "DJHS") conducted in 2000-2002. Results of the study are as follows: 1) Multimedia lessons were effective in increased learning, especially in Mathematics. 2) Student reactions to the multimedia lessons included "interesting", "useful" and "could concentrate." 3) Through the daily watching of TV in school, student\u27s visual comprehension skills improved significantly

「笠戸丸」マルチメディア用ソフトウェア試作資料(6)

This paper has three parts : Chapter One outlines several techniques devised by the author employed in designing educational materials using multimedia ; Chapter Two introduces one of these techniques used in designing a new video game called, "Where were these photographs taken?" This game was demonstrated by the author at the 2001 Convention of Japan Image Arts and Science Society held at Osaka Geijutsu University on June 3, 2001 ; Chapter Three explains some new information relating to the history of the Kasato Maru. The author has been studying this particular ship and its history for a number of years. Some interesting and significant coincidences occurred recently relating to this vessel. For example, on April 28, 2001, a statue commemorating the early twentieth century Japanese immigrants to Brazil was officially dedicated in Meriken Park in Kobe. Beside the statue, a painting of the Kasato Maru as she set sail from Kobe on April 28, 1908 was set up to help visitors understand the context of the dedication and the role of the ship in carrying immigrants to Brazil. Prior to this, there were few visual materials to help the artist in his depiction of the Kasato Maru, but the author was able to provide the artist with photographs of the ship and her construction plans, which were helpful to him in presenting an accurate portrayal of this historic ship. Also, it is important that the history of Japanese immigration to Brazil be understood today. This is because over 200, 000 descendants of these immigrants have returned to Japan to work and live ; it is necessary that they learn about this history and also that they learn the language and history of modern Japan. The Kasato Maru was used as a basis for the development of the educational software mentioned above. A prototype of the software was tested in demonstrations at the 2000 International Symposium on Japanese Language Teaching held last summer in Tokyo. Many Japanese language teachers from various countries and of differing nationalities field-tested this software at the symposium and the feedback from them was very positive, which encourages the author to further develop this as a basis for teaching materials software
