And to evaluate work rate from heart rate response, relationships between heart rate and O_2 uptake, heart rate and energy expenditure were measured simultaneously applying a step test on each subject, then the intensity of pruning work with each tool was estimated from the relationships. The mean values observed for O_2 uptake during hatchet and saw work were 21.7 and 23.3ml/kg/min, respectively, and for RMR, 5.34 and 5.81,respectively. But pruning speed of hatchet work was 14.5% smaller than that of saw work. The difference in work intensity with each pruning tool was not great, but saws were superior to hatchets for unskilled forest workers from the viewpoint of pruning speed.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062300","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0075739X","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"松原, 周信","creatorNameLang":"ja"},{"creatorName":"マツバラ, チカノブ","creatorNameLang":"ja-Kana"},{"creatorName":"Matsubara, Chikanobu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"瀧本, 義彦","creatorNameLang":"ja"},{"creatorName":"タキモト, ヨシヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Takimoto, Yoshihiko","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000079609.pdf","filesize":[{"value":"436.5 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079609.pdf","url":"https://kpu.repo.nii.ac.jp/record/5483/files/KJ00000079609.pdf"},"version_id":"6cb1328c-f0fd-4f05-9c28-60bf9c2c278c"}]},"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"}]},"item_title":"未熟練林業労働者における枝打ち作業の強度と功程(B. 生活科学)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"未熟練林業労働者における枝打ち作業の強度と功程(B. 生活科学)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["461"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5483","relation_version_is_last":true,"title":["未熟練林業労働者における枝打ち作業の強度と功程(B. 生活科学)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-05-31T01:41:48.368892+00:00"}
