The description of the characteristics of each city shown in Table 3 was insufficient, as was the reviewer's opinion. Accordingly, the project described in Table 3 was briefly explained and the contents of the article were also revised. - “... As a representative smart city project in Korea, Pilot city, Regulatory sandbox and Smart City Challenge are in progress. To summarize the smart city services used in this project, medical, crime prevention, transportation and environmental services are the most used.” Table 7 also agrees with the reviewer's advice that it does not fit the current content. Accordingly, the contents of Table 7 were deleted and only the contents described in the text were left. Thanks for your comments.
I think many cities and countries will not be comfortable with this approach.
