It is necessary for school officials to build a framework that includes concepts of security. Therefore we will research a realistic system that indicates the proper direction of an evacuation for children when the intruder invaded the elementary school. But it is difficult for us to decide a policy of implementing the proposed system because large scale experiments are needed to evaluate such a proposal system. For that reason, we determined specifications of the system on the theoretical side by simulating motions of children in a school building. As the result of simulations, it became clear that a default position measurement of the intruder is more important than a tracking of it with real-time so that children can escape from it in the elementary school. It was determined that existing technology could implement the proposed system.","subitem_description_type":"Other"}]},"item_28_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"KOGA, Kiyoshi"}]}]},"item_28_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部"}]},"item_28_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古賀, 潔"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"kaken06660291.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kaken06660291.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/8939/files/kaken06660291.pdf"},"version_id":"bba10702-ab84-4aec-9b2f-71a7a1592ba4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"consolidation","subitem_subject_scheme":"Other"},{"subitem_subject":"mercury intrusion porosimetry","subitem_subject_scheme":"Other"},{"subitem_subject":"permeability","subitem_subject_scheme":"Other"},{"subitem_subject":"secondary consolidation","subitem_subject_scheme":"Other"},{"subitem_subject":"二次圧密","subitem_subject_scheme":"Other"},{"subitem_subject":"圧密","subitem_subject_scheme":"Other"},{"subitem_subject":"水銀圧入法","subitem_subject_scheme":"Other"},{"subitem_subject":"透水性","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"粗・微細間隙構造からみた土の圧密機構の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"粗・微細間隙構造からみた土の圧密機構の研究"}]},"item_type_id":"28","owner":"3","path":["1505"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-10-19"},"publish_date":"2011-10-19","publish_status":"0","recid":"8939","relation_version_is_last":true,"title":["粗・微細間隙構造からみた土の圧密機構の研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:21:57.819491+00:00"}
