The authors noticed accidental mistakes existing in Sects. 2 and 3 of the original article (Lee and Kim 2018). In the Sect. 2, the authors deleted some part of second paragraph since it just copied with technical mistakes in progress. And in the Sect. 3, the authors changed citation style of third paragraph. This change does not affect the conclusions and results in the original publication. The authors would like to apologize for any inconvenience which this change may have caused.

Deleted part of second paragraph in Sect. 2:

In the Sect. 2, 15th to 41st lines “Furthermore…, could not provide corresponding improvement strategies to managers.” should be deleted.
