Five patterns of road and cable positions were calculated under the following condition. The size of site is 0.4ha, 0.9ha, and 1.6ha, shape is oblong, square, and rectangle, distance from forest road is 100m, 300m, and 500m. For the small site, to set the mobile-yarder and the processor away from the site is the most profitable one. In the case of middle site, to construct skidding road close to the site, and not to move the mobile-yarder is profitable. In the case of large site, if the depth of the site is longer than width, to construct skidding road to the middle area of the site and to move the landing is profitable.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54256","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKURAI, Rin"}]},{"nameIdentifiers":[{"nameIdentifier":"54257","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKAI, Hideo"}]},{"nameIdentifiers":[{"nameIdentifier":"54258","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Hiroshi"}]}]},"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森林科学専攻"},{"subitem_text_value":"Department of Forest Science, Guraduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"櫻井, 倫"}],"nameIdentifiers":[{"nameIdentifier":"54253","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"54254","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"54255","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":"esrh105005.pdf","filesize":[{"value":"680.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh105005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25357/files/esrh105005.pdf"},"version_id":"14b66e3c-3a8b-4060-8426-db89125693d7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"集材路","subitem_subject_scheme":"Other"},{"subitem_subject":"シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"伐区形状","subitem_subject_scheme":"Other"},{"subitem_subject":"林道から伐区までの距離","subitem_subject_scheme":"Other"},{"subitem_subject":"伐区面積","subitem_subject_scheme":"Other"},{"subitem_subject":"skidding road","subitem_subject_scheme":"Other"},{"subitem_subject":"simulation","subitem_subject_scheme":"Other"},{"subitem_subject":"shape of site","subitem_subject_scheme":"Other"},{"subitem_subject":"distance from forest road to site","subitem_subject_scheme":"Other"},{"subitem_subject":"area of site","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":"タワーヤーダー・プロセッサ・フォワーダ型集運材作業システムにおける集材路と架線の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"タワーヤーダー・プロセッサ・フォワーダ型集運材作業システムにおける集材路と架線の検討"}]},"item_type_id":"4","owner":"1","path":["2532","2531"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25357","relation_version_is_last":true,"title":["タワーヤーダー・プロセッサ・フォワーダ型集運材作業システムにおける集材路と架線の検討"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.350814+00:00"}
