First, I performed CT scaning of this specimen, got about 1, 200 sliced imaging dataset. Secondly, I made volume rendering image on the software(Molcer Plus), three three space coodinates were calculated on the 3D axes, and calculate normal vector of each 3D plane. Each origin of normal vector replaced to each center of ommatidium, and the optical axis of each ommatidium were determined. By makng globular chart of each optical axis, I estimated the visual field of the Cyclopyge sp. The result showed that the visual field of Cyclopyge sp. was narrow(about 120 degrees in each left and right lateral side) and their density was higher in the ventral side than the dorsal one. This result indicated that the Cyclopyge sp. was possible upside down swimmer.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"出典：研究課題「三葉虫はスキソクローラル・アイでどのように物を見ていたか」課題番号21740370\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-21740370/21740370seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学国際基幹教育院GS教育系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052333","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=50437191"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=50437191","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-21740370/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-21740370/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-21740370/21740370seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-21740370/21740370seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-28"}],"displaytype":"detail","filename":"GS-PR-TANAKA-G-kaken 2012-5p.pdf","filesize":[{"value":"292.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"GS-PR-TANAKA-G-kaken 2012-5p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45999/files/GS-PR-TANAKA-G-kaken 2012-5p.pdf"},"version_id":"72c25b6b-2059-4aaa-9fc1-7864b86f84a8"}]},"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":"三葉虫はスキソクローラル・アイでどのように物を見ていたか","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"三葉虫はスキソクローラル・アイでどのように物を見ていたか"},{"subitem_title":"How did the trilobite see the world by using the Schizochroral eye?","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2822"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-04"},"publish_date":"2018-10-04","publish_status":"0","recid":"45999","relation_version_is_last":true,"title":["三葉虫はスキソクローラル・アイでどのように物を見ていたか"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:26:50.729643+00:00"}
