Research Abstract

平成2年10月8、9日の2日間に福井県三国観光ホテルで研究・討論会を開催し、26件の研究発表が行なわれた。主な発表題目は下記のとおりである。分担研究者の発表内容を大別すると、「非平衡系および平衡系の示すゆらぎ現象」、「ゆらぎの引込現象」、「ゆらぎと生体の自己組織化」、「脳波のゆらぎの意味」に関するもので、特別講演は「ゆらぎ」を電力系との安定性に利用したもので、「ゆらぎを用いた電力系統の全域的安定性監視」(東北大学、豊田淳一教授)と題して行なわれた。生体のゆらぎとのアナロジ-について活発な討議が行なわれた。
また本年度はこの総合研究の最終年度になるので、各研究分担者からまとめの報告書を提出してもらい研究報告書を製作して関連研究者に配布した。
