When the index of productivity of the manual timber processing on felling site was assumed to 100, in the thinning operation, the index of productivity of the prototype table-processor, which had been recently developed in Japan, was 306, and that of boom-processor was 1098. In the final felling operation, they were 313, 1792 respectively. And the allowable machine cost was also analyzed. When we machanize the timber processing operation, the machine, which costs 15 million yen, could be available, if the productivity would be raised to three times as that of before the mechanization. Then we could estimate that the machine of 23 million yen would be available if the productivity was raised to so much as 17 times as that of before the mechanization.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55481","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MINAMIKATA, Yasushi"}]},{"nameIdentifiers":[{"nameIdentifier":"55482","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NITAMI, Toshio"}]},{"nameIdentifiers":[{"nameIdentifier":"55483","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKAI, Hideo"}]},{"nameIdentifiers":[{"nameIdentifier":"55484","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ITO, Koya"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"東京大学農学部付属秩父演習林"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"},{"subitem_text_value":"University Forest at Chichibu, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南方, 康"}],"nameIdentifiers":[{"nameIdentifier":"55477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仁多見, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"55478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"55479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤, 幸也"}],"nameIdentifiers":[{"nameIdentifier":"55480","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":"esrh076007.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh076007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25580/files/esrh076007.pdf"},"version_id":"a63ea799-5dc8-48cd-850c-4d2102667a54"}]},"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":"機械化造材作業の時間分析と造材作業機械化の可能性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"機械化造材作業の時間分析と造材作業機械化の可能性"}]},"item_type_id":"4","owner":"1","path":["2590","2589"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25580","relation_version_is_last":true,"title":["機械化造材作業の時間分析と造材作業機械化の可能性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:46.257492+00:00"}
