니까 떠오르다

that reminds me

"-(으)니까" gives the trigger and 떠오르다 is "come to mind, float up". The five lines here are all the same move: something in front of the speaker sets off a thought. Looking at the road atlas gave me the idea, speaking of concerts reminds me of something, seeing the cup brought up a topic, mentioning careers made me think of my daughter. It is how a conversation pivots, and it is usually said as the new subject arrives rather than planned.
