Waves produced by the normal use of chain-saw, pneumatic hammer, pneumatic riveting hammer, and pneumatic nailer at workplaces was recorded and analyzed. The order of the size in the impulsiveness, crest factor (CF) was chain-saw, pneumatic hammer, pneumatic riveting hammer, and pneumatic nailer at a constant frequency-weighted rms acceleration at x direction (a_<xhw>) of 6.3 m/s^2. No statistically significant effects of shock was recognized in comparisons of subjective response to shock-type vibration with that to shockless vibration of shain-saw. Effects of shock on peripheral circulation was examined by monitoring finger skin blood flow induced by the shock-type vibration at a constant frequency-weighted rms acceleration at x direction (a_<xhw>) of 6.3 m/s^2. In a result, pneumatic nailer with the CF of 9.5 produced significant decreases in the blood flow at 4 and 5 min after the exposure. This result suggests that effects of vibration should be assessed including the size of the impulsiveness. Experiments examining effects of hand-grasping showed significant reduction in peripheral blood flow associated with the grasping. Tools with measures which protect vibration from transmitting into hand-arm easily with the growth of grasping force should be developed in future.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:04454222, 研究期間(年度):1992 – 1993","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「衝撃型振動の手腕系末梢循環動態に及ぼす影響に関する研究」課題番号04454222\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-04454222/044542221993kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学学長","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00066848","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=10019573"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=10019573","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-04454222/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-04454222/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-04454222/044542221993kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-04454222/044542221993kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-07-25"}],"displaytype":"detail","filename":"ME-PR-OKADA-A-kaken 1999-2p.pdf","filesize":[{"value":"84.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-OKADA-A-kaken 1999-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/60601/files/ME-PR-OKADA-A-kaken 1999-2p.pdf"},"version_id":"d5d394a3-25cf-4048-bf3f-847a6eeaaba7"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"衝撃型振動の手腕系末梢循環動態に及ぼす影響に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"衝撃型振動の手腕系末梢循環動態に及ぼす影響に関する研究"},{"subitem_title":"Study on Effects of Shoch-Type Vibration on Peripheral Circulation in the Hand-Arm","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2840"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-07-25"},"publish_date":"2022-07-25","publish_status":"0","recid":"60601","relation_version_is_last":true,"title":["衝撃型振動の手腕系末梢循環動態に及ぼす影響に関する研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:36:12.696497+00:00"}
