An experimental apparatus of Raman spectroscopy was manufactured with simple operation and high acquisition rate and the accelerated exposure pieces were prepared as a standard degradation sample in the first stage. We have found useful correlation between some peak intensities in the plastic Raman spectra and the degree of deterioration of plastics. In order to improve the degradation evaluation, we have also technologically developed a signal gaining method based surface-enhanced Raman scattering (SERS) with silver nanoparticles and a numerical data analysis method with support vector machine (SVM) of pattern recognition for the Raman spectra.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2015～2017;   課題番号：15K05589;   研究分野：レーザ分光分析;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K05589/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"KAWAZUMI, Hirofumi"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学産業理工学部; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河濟, 博文"},{"creatorName":"カワズミ, ヒロフミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"33662","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10150517","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-22"}],"displaytype":"detail","filename":"15K05589seika.pdf","filesize":[{"value":"605.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"15K05589seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/19790/files/15K05589seika.pdf"},"version_id":"b363be49-a985-4137-af47-bbb154c98ef6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"プラスチック識別","subitem_subject_scheme":"Other"},{"subitem_subject":"プラスチック劣化","subitem_subject_scheme":"Other"},{"subitem_subject":"ラマン分光法","subitem_subject_scheme":"Other"},{"subitem_subject":"表面増強ラマン","subitem_subject_scheme":"Other"},{"subitem_subject":"銀ナノ粒子","subitem_subject_scheme":"Other"},{"subitem_subject":"サポートベクターマシン","subitem_subject_scheme":"Other"},{"subitem_subject":"主成分分析","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ラマン散乱によるプラスチック劣化計測法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ラマン散乱によるプラスチック劣化計測法の開発"},{"subitem_title":"Development of evaluation techniques for plastic degradation based on Raman spectroscopy","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4459"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-22"},"publish_date":"2018-11-22","publish_status":"0","recid":"19790","relation_version_is_last":true,"title":["ラマン散乱によるプラスチック劣化計測法の開発"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:34:05.618056+00:00"}
