I found via Google that Eun Ju Lee (Dong-Eui University, South Korea, [email protected]) and Jee Hyun Rho Pusan (National University, South Korea, [email protected]) seem to have published a study concerning renovation of Public Libraries in South Korea. It may be relevant to get contact with them.
I suggest, that you formulate a more specific point of view. It helps in achieving relevant information.
The article "Libraries in the Republic of Korea" written by Margaret Adolphus may help you and here is the link https://www.emeraldgrouppublishing.com/archived/librarians/management/viewpoints/korea.htm
