There are also many in-text reference errors with tables, which makes it hard to follow given the high number of tables (13!).
I have some theoretical questions about the applicability of these approaches outside of Korea. For technical reasons (most smart cities have less capability and are less developed than Korean ones), but especially for legal and normative reasons (concerns about surveillance, governance, cybersecurity, etc.) I think many cities and countries will not be comfortable with this approach. I think this needs some exploration.
