In the case of Korea, rather than finding the infected person in advance, the focus was on identifying and blocking the spread of the infected person. Therefore, Smart City Service checked the movement of the infected people by time, found close contacts in the vicinity, and took measures to self-quarantine immediately. As a result, the critical point of being identified before an infectious disease spreads was missed. However, Korea has prevented a rapid collapse of the medical system by slowing the rate of propagation around it, and the role of smart city services has been significant in this regard.

Reflecting the reviewer's opinion that it is not clear, the entire sentence has been revised and translated clearly.
