They ARE VERY different. "homework" is schoolwork from teachers: math problems, writing, etc. "housework" is cleaning, cooking, etc. at home. A husband who confuses the two terms will surely get himself into trouble! ("Today my teacher gave me housework to do.")
BTW: I have not seen the expression "aspect significated" used in the USA. "significate" could be UK English, but I suspect that it is "Spanglish" derived from "significar".
