Perhaps you should try some spelling variations:
dung thang » hung thang, cung thang, dung thuong
tinh huong » dinh huong, tinh quang, anh huong
huong luan » huong lan, cuong luan, huong loan
dung toan » dung doanh, dung thanh, dung tai
hieu soat » hieu suat, hieu hoat, hieu luat
kiem soat » kiem toan
tap hieu » tap sieu, thap chieu, phap hieu
van kiem » va kiem, van kien, van hieu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( trinh ((dung toan) OR (dung thang)) tap hieu soat ) OR ( tinh huong luan van kiem soat ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( trinh ((dung toan) OR (dung thang)) tap hieu soat ) or ( tinh huong luan van kiem soat ))~".
• Adding a wildcard symbol may retrieve word variants: (( trinh ((dung toan) OR (dung thang)) tap hieu soat ) or ( tinh huong luan van kiem soat ))*.
