In the preliminary investigation of the sound data immediately before suction, immediately after suction, and at the distal part of the pharyngeal prominence during normal periods, we could extract a 1.2kHz characteristic sound that appeared only immediately before suction. Next, we created teacher data from the data used in the preliminary investigation. When we investigated with sound data immediately before suction within the same individual, there was a definite high correlation of 0.95 or more. Based on the above results, it may be possible to differentiate the timing between immediately before phlegm expulsion and immediately after phlegm expulsion by extracting the characteristic adventitious sounds within a specific individual. Monitoring the frequency of data with high correlation levels may also enable estimation of the optimal timing for phlegm expulsion. Characteristic sounds may observe in this study differed depending on the physique and disease of the target. Further investigation is needed to verify if the same results can be observed in other types of adventitious sounds.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13462180","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11358555","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"490","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉満, 孝二","creatorNameLang":"ja"},{"creatorName":"YOSHIMITSU, Koji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"千種, 芳幸","creatorNameLang":"ja"},{"creatorName":"CHIGUSA, Yoshiyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"平嶋, 佑太郎","creatorNameLang":"ja"},{"creatorName":"HIRASHIMA, Yutaro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"丸田, 道雄","creatorNameLang":"ja"},{"creatorName":"MARUTA, Michio","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-06"}],"displaytype":"detail","filename":"AA11358555_v30_n1_p9-14.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11358555_v30_n1_p9-14","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/15631/files/AA11358555_v30_n1_p9-14.pdf"},"version_id":"0da0904d-c02c-431c-9901-b2568fef459a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"副雑音","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"喀痰吸引","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"予測","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"音響解析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"adventitious sounds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"suction of phlegm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"prediction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"analysis of sounds","subitem_subject_language":"en","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":"貯痰時に副雑音に含まれる特徴量の解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"貯痰時に副雑音に含まれる特徴量の解析","subitem_title_language":"ja"},{"subitem_title":"Analysis of Characteristic Sounds Included in the Adventitious Sounds During a Phlegm Accumulates","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["103","5995"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-01-06"},"publish_date":"2021-01-06","publish_status":"0","recid":"15631","relation_version_is_last":true,"title":["貯痰時に副雑音に含まれる特徴量の解析"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-01-30T01:37:20.488099+00:00"}
