On a community website where I spend a lot of time, someone asked recently for advice on how to deal with his noisy neighbours. He doesn't live in Korea, but he thought that the couple next door was Korean, and that when they were shouting at each other in the wee hours, they weren't shouting in English. He reasonably took this as an indication that some knowledge of their cultural background could come in handy if he girded his loins enough to talk to them about it.
