In Korean culture, it is common to use the title 'Professor' (교수님) as a substitute for the person's name when addressing them.

In South Korea, 교수님 is often used as a respectful title for someone who is an expert in their field, even if they do not actually teach at a university.
The word 교수 is composed of two characters that literally mean 'to teach' and 'to give'. It is as if you are describing the act of 'giving instruction' rather than just a job title.
In some traditional academic settings, a professor might be called 스승님, a word that translates to 'master' or 'mentor' rather than just 'teacher'.
