As a result, more stable and reliable monitoring of the cardiovascular hemodynamic parameters were made on a beat-by-beat basis under various ambulatory situations. The replacement of the band-electrode to spot-electrode in the admittance cardiography was also successfully performed on a sitting position using the 64-ch impedance mapping system. ・Estimation of autonomic nervous activity under daily life : Using the new monitoring system, cardiovascular parameters were successfully monitored on the subjects during their daily life activities. The changes of the parameters were corresponded to the subject's postures and activities as almost the same as the previous studies obtained in the laboratory and hospital testings. With regard to the analysis of the parameters, the calculation of the baro-receptor cardiac reflex sensitivity based on the Bertinieri's method, and the analysis of the power spectrum density and the transfer function were made, and it was continued to be able to estimate the vagal and sympathetic activities under daily activities except strong exercises. It was also suggested that the analysis of the total peripheral resistance change following the posture change from sitting to standing was more suitable for the estimation of the sympathetic activity during exercise.","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:09480252, 研究期間(年度):1997–1999, 平成11(1999)年度科学研究費補助金 基盤研究(B) 研究成果報告書の一部, 総論(はしがき, 研究概要, 研究成果概要)を掲載。","subitem_description_type":"Other"},{"subitem_description":"出典：「日常行動下における自律神経系による循環調節機序の解析に関する研究」研究成果報告書　課題番号09480252\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　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00034842","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学工学部"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=40014310","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-09480252/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-09480252/094802521999kenkyu_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":"2017-10-05"}],"displaytype":"detail","filename":"TE-PR-YAMAKOSHI-K-kanen 2000-47p.pdf","filesize":[{"value":"6.5 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-YAMAKOSHI-K-kanen 2000-47p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34855/files/TE-PR-YAMAKOSHI-K-kanen 2000-47p.pdf"},"version_id":"ad089c3b-6535-4ef0-95a4-14cc0737628c"}]},"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":"日常行動下における自律神経系による循環調節機序の解析に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日常行動下における自律神経系による循環調節機序の解析に関する研究"},{"subitem_title":"A study on the cardiovascular hemodynamic regulation by autonomic nervous system under human daily activities using ambulatory beat-by-beat cardiovascular monitoring system","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2834"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34855","relation_version_is_last":true,"title":["日常行動下における自律神経系による循環調節機序の解析に関する研究"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:48:59.220162+00:00"}
