My Topic of Research project

I dicided about adopted children. When I was high school, I attended the public service for 3 days. There were many children because the children was abandoned from parants. They had a pretty smile. I thougt that after I get married, I will adopt a child. Nowaday, Many people adopt children. I want to reserch between North America and Korea(Asia) because their adopted method and perception is different. For example, homosexual can't married in Korea, but They can married and adopt children in Canada. Also I want to investigate the types of adoption and reasons for adoption.
