Perhaps you should try some spelling variations:
tinh thong » tinh thuong, trinh thong, tinh khong
tinh dung » trinh dung, tin dung, tinh quang
kiem soat » kiem toan
kien soat » bien soan, kien hoa, kiem sat
dien hoat » dien hoa, dien hat, trien hoat
van kiem » va kiem, van kien, van hieu
quan van » quan va, quan luan, quan doan
luan » lan

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: (( tinh dung luan van kiem soat ) OR ( tinh thong quan van ((kien soat) OR (dien hoat)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung luan van kiem soat ) or ( tinh thong quan van ((kien soat) OR (dien hoat)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van kiem soat ) or ( tinh thong quan van ((kien soat) OR (dien hoat)) ))*.
