After the Great East Japan Earthquake, the importance of aggregate as a basic material was reaffirmed, and the demand for aggregate is currently in a slight increase or leveling off, and the annual production has been around 380 million tons. In this review, overviewing the transition of aggregate production in Japan from the viewpoint of aggregate resources, the current issues and future prospects are explained. It mentions the shift to mining method in harmony with the environment to enable “sustainable development” on the premise of coexistence with the region, which is an important issue in the mining and production of aggregate. Then, it will be described that trends such as the construction of smart mining system that utilize ICT, IoT, AI, etc. with the aim of responding to labor shortages due to the declining birthrate, aging population, and the advent of a declining population.", "subitem_description_type": "Other"}]}, "item_16_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "96094", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "OTSUKA, Naohiro"}]}]}, "item_16_link_13": {"attribute_name": "抄録（URL）", "attribute_value_mlt": [{"subitem_link_text": "わが国における骨材生産の推移と今後の展望", "subitem_link_url": "https://www.jstage.jst.go.jp/article/journalofmmij/138/5/138_60/_article/-char/ja/"}]}, "item_16_publisher_14": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "資源・素材学会"}]}, "item_16_relation_26": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.2473/journalofmmij.138.60", "subitem_relation_type_select": "DOI"}}]}, "item_16_rights_18": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2022 The Mining and Materials Processing Institute of Japan"}]}, "item_16_rights_19": {"attribute_name": "権利URI", "attribute_value_mlt": [{"subitem_rights": "https://creativecommons.org/licenses/by-nc-nd/4.0/deed.ja"}]}, "item_16_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "18840450", "subitem_source_identifier_type": "ISSN"}, {"subitem_source_identifier": "18816118", "subitem_source_identifier_type": "ISSN"}]}, "item_16_text_4": {"attribute_name": "著者(機関)", "attribute_value_mlt": [{"subitem_text_value": "岩手大学"}]}, "item_16_version_type_27": {"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": "大塚, 尚寛"}], "nameIdentifiers": [{"nameIdentifier": "95468", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2023-01-10"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "jmmij-v138n5p60-69.pdf", "filesize": [{"value": "3.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3000000.0, "url": {"label": "jmmij-v138n5p60-69", "url": "https://iwate-u.repo.nii.ac.jp/record/15867/files/jmmij-v138n5p60-69.pdf"}, "version_id": "1ac4591e-ef88-40b6-9cc1-fe2e4b2c8f79"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "骨材", "subitem_subject_scheme": "Other"}, {"subitem_subject": "砕石", "subitem_subject_scheme": "Other"}, {"subitem_subject": "砂利", "subitem_subject_scheme": "Other"}, {"subitem_subject": "持続可能な開発", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ICT", "subitem_subject_scheme": "Other"}, {"subitem_subject": "スマート採掘システム", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Aggregate", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Crushed Stone", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Gravel", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Sustainable Development", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ICT", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Smart Mining System", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "わが国における骨材生産の推移と今後の展望", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "わが国における骨材生産の推移と今後の展望"}, {"subitem_title": "Trend and Future Prospect of Aggregate Production in Japan", "subitem_title_language": "en"}]}, "item_type_id": "16", "owner": "19", "path": ["1519"], "permalink_uri": "https://iwate-u.repo.nii.ac.jp/records/15867", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-01-10"}, "publish_date": "2023-01-10", "publish_status": "0", "recid": "15867", "relation": {}, "relation_version_is_last": true, "title": ["わが国における骨材生産の推移と今後の展望"], "weko_shared_id": -1}
