The total days of measuring failure were measured and the cause of failure analyzed. Over the study period, the problems which occurred had to be forecast and the items necessary for the solution of these problems collected. After construction of the system, it was necessary to clarify the problems which appeared for the first time when the system was used and to improve the system. Modification of the system made it necessary to undertake local operational tests of the equipment so, inevitably, the possibility of measurement failure became high. The system, both the current one and the modified one, had to be duplicated and it was desirable to carry out usage tests over an entire season. It was necessary to simplify procedures for changing videotapes and to configure the exchange schedules in advance in order to avoid simple mistakes of in the exchange procedure and unexpected lags of exchange. Because breakdown of the equipment was the result of a number of causes, and in order to hold down the period of measurement failure to a minimum, it was necessary to discover breakdowns early and to prepare an alternative device as soon as possible in order to prepare for quick change-over.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54052","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUJIWARA, Akio"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科附属科学の森教育研究センター秩父演習林"},{"subitem_text_value":"University Forest in Chichibu, University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤原, 章雄"}],"nameIdentifiers":[{"nameIdentifier":"54051","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh110004.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh110004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25327/files/esrh110004.pdf"},"version_id":"b75b0dba-e9c5-4f19-a768-78d853b4003f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"森林","subitem_subject_scheme":"Other"},{"subitem_subject":"ビデオ","subitem_subject_scheme":"Other"},{"subitem_subject":"長期記録","subitem_subject_scheme":"Other"},{"subitem_subject":"ロボットカメラ","subitem_subject_scheme":"Other"},{"subitem_subject":"技術開発","subitem_subject_scheme":"Other"},{"subitem_subject":"forest","subitem_subject_scheme":"Other"},{"subitem_subject":"video","subitem_subject_scheme":"Other"},{"subitem_subject":"long-term recording","subitem_subject_scheme":"Other"},{"subitem_subject":"robot camera","subitem_subject_scheme":"Other"},{"subitem_subject":"engineering development","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"天然林樹冠部ロボットカメラの長期連続運用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"天然林樹冠部ロボットカメラの長期連続運用"}]},"item_type_id":"4","owner":"1","path":["2522","2521"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25327","relation_version_is_last":true,"title":["天然林樹冠部ロボットカメラの長期連続運用"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:00:48.092972+00:00"}
