tinh dung » trinh dung, tin dung, tinh quang
hieu soat » hieu suat, hieu hoat, hieu luat
quan dong » quang dong, quan hoang, quan trong
quan long » quan lang, quan hoang, quan trong
kiem soat » kiem toan

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh dung luan van hieu soat ) or ( dinh luong ((quan dong) OR (quan long)) kiem soat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh dung luan van hieu soat ) OR ( dinh luong ((quan dong) OR (quan long)) kiem soat )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung luan van hieu soat ) or ( dinh luong ((quan dong) OR (quan long)) kiem soat ))".
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van hieu soat ) or ( dinh luong ((quan dong) OR (quan long)) kiem soat ))*.
