Since its inception of the NUD*IST program, I have kept following as a user of NVivo 12. Two decades of my involvement in NVivo has made me an NVivoist in Korea without even my awareness. I also published 20 books on NVivo, and there was always a recurring theme through workshops organized by me. That is, what is the most difficult function for workshop participants to acquire and why? Will we be able to advance the graduation time consumed for the thesis if we understand the important functions necessary for the publication? In response to this question, this book will demonstrate how to import and code various qualitative data in NVivo R1.
