"The beautiful woman asks about cultural problems."
Translation:아름다운 여자가 문화적인 문제에 관해서 물어요.
서 ~ on / while
관하다 - to refer to, to relate to etc. -> 관해 (conjugated form)
관해서 ~ while/on referring to / while/on relating to = about
관해 ~ referring to / relating to = about [short form of 관해서]
Like in English, 서 (on / while) can be omitted without affecting the rest of the sentence.
