Thank you for your question. Might I recommend that you research your question more thoroughly before asking it?
A simple google search says 'Culture includes' not 'concludes.' Also, culture is not a person, so I don't see how 'culture' could (in of itself) reach a conclusion. "Includes', however, is proper English both syntactically and semantically.
Please double-check your question and verify that you're using the correct verb.
