If you want audio, your best bet is probably YouTube. (search for 건강 뉴스, 건강 과학, 건강 백과, etc) There's one like this for example (professional-like presentation) - https://www.youtube.com/watch?v=oG-Aaj0Iu_I And one like this intended fro students (like a real life teacher) - https://www.youtube.com/watch?v=vKxSJgM2Rl4 There seem to be a lot just on YT - you can look around and find a channel you like.
