A helicopter, type of Bell 204B-Ⅱ, extracted 388㎥ (467t) of timbers from seven logging sites. We observed and analyzed the yarding operations of three logging sites among them. Results of the time study were arranged in table 4 and figure 8. The characteristics of the helicopter logging in Horai-cho were; 1) Timber extraction from several yarding areas, 2) Yarding of both small thinned logs and large tree-length logs, 3) Small landings and small heliports built in several separate places because of steep terrain condtions. The helicopter logging is usually performed independently of ground conditions and, therefore, is one of the most stable operations in all logging methods. This was ascertained by the small value of the standard deviation of observed cycle times. Even in thinning or selective cutting operation, the yarding performance of helicopter keeps a rather high level despite of a little delay for some difficulties in hooking-up at yarding area. The helicopter logging is considered more suitable to thinning and selective cutting operations than other conventional methods, such as cable logging and tractor logging. For successful introduction of helicopter logging into private forests, the followings should be considered carefully; 1) Co-operations of forest owners in the region, 2) Careful planning and preparations at yarding area and landing, 3) Harvesting sufficient timber volume to reduce logging cost.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"農林水産研究情報センターで作成したPDFファイルを使用している。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"http://rms1.agsearch.agropedia.affrc.go.jp/contents/JASI/pdf/academy/40-2640.pdf"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8662"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/bulnuf.9.6","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学農学部付属演習林","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0469-4708","subitem_source_identifier_type":"PISSN"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森岡, 昇","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18753","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MORIOKA, Noboru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18754","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北川, 勝弘","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18755","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KITAGAWA, Katsuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18756","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"近藤, 稔","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18757","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KONDO, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中山, 学","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18759","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAKAYAMA, Manabu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18760","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":"2018-02-19"}],"displaytype":"detail","filename":"bulnuf_9_6.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bulnuf_9_6.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/6991/files/bulnuf_9_6.pdf"},"version_id":"d54a33d6-6c56-41f5-97b6-fbcfefd7753f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ヘリコプター集材作業","subitem_subject_scheme":"Other"},{"subitem_subject":"時間分析","subitem_subject_scheme":"Other"},{"subitem_subject":"民有林","subitem_subject_scheme":"Other"},{"subitem_subject":"間伐材集材","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":"ヘリコプター集材作業の時間分析 : 愛知県鳳来町の民有林における事例","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヘリコプター集材作業の時間分析 : 愛知県鳳来町の民有林における事例","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["864"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-08-15"},"publish_date":"2007-08-15","publish_status":"0","recid":"6991","relation_version_is_last":true,"title":["ヘリコプター集材作業の時間分析 : 愛知県鳳来町の民有林における事例"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T05:18:51.491718+00:00"}
