月1 日から石川県第3 波期中である2021年3 月8 日までの798日の，それぞれ4 時，14時，19時の3 時点について，石川中央都市圏内4 市2 町（金沢市・白山市・野々市市・かほく市・内灘町・津幡町）を対象とした，500m×500mで区切られた1053メッシュ内人口データを使用とした。すなわち2394時系列（798日×3時点）×1053メッシュデータ行列を作成し，非負値行列因子分解を用いてデータ解析を行った。\n　分析結果として，非負値行列因子分解の基底数を3 とした時，すなわち上記のデータを3 次元の特徴空間に次元縮約すると，「滞在の行動（就寝）」，「平日の外出行動（就業・就学）」，「休日の外出行動（観光・夜間）」の基底が抽出された。いずれの基底のおいても，特に2020年4 月から5月にかけて発生したCOVID-19の第１波流行期及び緊急事態宣言期間中に生活行動が大きく変化しており，緊急事態宣言解除後の2020年6 月頃にはおおよそ宣言前の水準にまで生活行動が戻っていた。しかし「平日の外出行動（就業・就学）」，「休日の外出行動（観光・夜間）」においては，いずれも2019年の水準までには回復しておらず，依然としてCOVID-19の影響が石川県内においても見られる。","subitem_description_type":"Abstract"}]},"item_7_heading_33":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"論文","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Articles","subitem_heading_language":"en"}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00064102","subitem_identifier_reg_type":"JaLC"}]},"item_7_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"金沢大学大学院人間社会環境研究科
