[AI/Octagon/Well-being]Kinoshita, S., Furukawa, S., Ikkatai, Y., & Yokoyama, H. M. (2025). Cross-National Ethical Concerns Toward AI-Based Well-Being Measurement: A Comparative Study Across Finland, Germany, Japan, and the United States Using the Octagon Framework. International Journal of Human–Computer Interaction, 1–23. https://doi.org/10.1080/10447318.2025.2596861

This study examines public attitudes toward using artificial intelligence to measure human subjective well-being from biometric data, contributing empirical evidence to AI ethics research.Scenario acceptability varied contextually, with healthcare applications eliciting the least resistance and governance-related applications the most. / AIで生体認証を行うシステムでは医療については需要度が高く監視につながるシステムについては低かった。

This paper covers three points: 1) the history of the launch of the SK and HK series of big science projects and university bonds, which are representative of big science in Japan; 2) big science policy, specifically the history of the 2010-2022 Science Council of Japan master plan and the MEXT Roadmap, as well as the evaluation by scientists and the public of the relationships and evaluation items; and 3) the recognition by the regional public of the importance of the ILC as a basic science project rather than a regional development project./この論文では、3つの点について述べています。①日本を代表するビッグサイエンスであるSK、HKシリーズと大学債のスタートの経緯、②ビッグサイエンスの政策、具体的には2010-2022の学術会議のマスタープランと、文科省のロードマップの経緯、関係と評価項目に対する科学者と公衆の評価、③ILCに対する地域別の公衆が地域振興ではなく基礎科学として重要かどうかを認識している点です。
