Additionally, I've included a few other pieces on COVID and smart cities.
It presents phased plans for pandemics. Several different plans are described, which is useless information for the reader. Indeed, the phases in a Texan county are of no use to understand the authors’ contribution. They could easily break the section down to the essential information that would be the WHO phases and the Korean healthcare phases, and mention that there are global and local plans throughout the world with different phases. Tables 8 and 9 can thus be removed. Table 7 is not very informative, all the phases say that actions from the previous phase should be continued or initiated. I have checked the online source and it mentions other aspects such as treatment and isolation for the recognition phase, which have not been picked up by the authors. A case study approach restricted to Korea would be more informative and more consistent with the contribution of the paper, which is as I mentioned specific to Korea.
