The genus Mirifusus, a group of Mesozoic radiolaria, has a character of detailed and geometric frame between segments. The geometric framework was evolved from combination of pentagon and rhombus to triangle through pentagon. We treated such frameworks as two dimensional rigid frames with periodic boundary condition. We obtained normalized displacement of upper-side under the condition of compress or tortional force for each framework. The results show that the triangle structure is most effective if the 2-D frame is applied both of compress and torsional forces in most cases. Such a structure corresponds to final frame structure of genus Mirifusus during its evolution process.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39353","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshino, Takashi"}]},{"nameIdentifiers":[{"nameIdentifier":"39354","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ishida, Naoto"}]},{"nameIdentifiers":[{"nameIdentifier":"39355","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kishimoto, Naoko"}]},{"nameIdentifiers":[{"nameIdentifier":"39356","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuoka, Atsushi"}]},{"nameIdentifiers":[{"nameIdentifier":"39357","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kurihara, Toshiyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"39358","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kimoto, Katsunori"}]},{"nameIdentifiers":[{"nameIdentifier":"39359","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuura, Shu"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://plankton.random-walk.org/wp-content/uploads/2010/05/090714appliedMechREV.pdf","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"公益社団法人土木学会"},{"subitem_rights":"本文データは学協会の許諾に基づきWebから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12492021","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13459139","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉野, 隆"}],"nameIdentifiers":[{"nameIdentifier":"39346","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石田, 直人"}],"nameIdentifiers":[{"nameIdentifier":"39347","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岸本, 直子"}],"nameIdentifiers":[{"nameIdentifier":"39348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松岡, 篤"}],"nameIdentifiers":[{"nameIdentifier":"39349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"栗原, 敏之"}],"nameIdentifiers":[{"nameIdentifier":"39350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木元, 克典"}],"nameIdentifiers":[{"nameIdentifier":"39351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松浦, 執"}],"nameIdentifiers":[{"nameIdentifier":"39352","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"12_35-42.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"12_35-42.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2834/files/12_35-42.pdf"},"version_id":"f5ee013b-51ff-4bd8-89dc-f5389e0a4d2e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"radiolaria","subitem_subject_scheme":"Other"},{"subitem_subject":"genus Mirifusus","subitem_subject_scheme":"Other"},{"subitem_subject":"frame structure","subitem_subject_scheme":"Other"},{"subitem_subject":"structural mechanics","subitem_subject_scheme":"Other"},{"subitem_subject":"evokution","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"放散虫Mirifusus属（海洋プランクトン）の進化と骨組構造の力学的最適化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"放散虫Mirifusus属（海洋プランクトン）の進化と骨組構造の力学的最適化"},{"subitem_title":"放散虫Mirifusus属（海洋プランクトン）の進化と骨組構造の力学的最適化","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-01-20"},"publish_date":"2014-01-20","publish_status":"0","recid":"2834","relation_version_is_last":true,"title":["放散虫Mirifusus属（海洋プランクトン）の進化と骨組構造の力学的最適化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:01.547726+00:00"}
