benh khong » benh kho
khong quan » thong quan, hong quan, thong quang
kiem soat » kiem toan
hien luat » hieu luat, hieu suat
quan van » luan van, quan va, quan doan
tri hien » tri chien, thi hien, tri kien

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tin phuong ((quan van) OR (quan luan)) kiem soat ) or ( benh khong quan tri hien luat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tin phuong ((quan van) OR (quan luan)) kiem soat ) OR ( benh khong quan tri hien luat )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tin phuong ((quan van) OR (quan luan)) kiem soat ) or ( benh khong quan tri hien luat ))".
• Adding a wildcard symbol may retrieve word variants: (( tin phuong ((quan van) OR (quan luan)) kiem soat ) or ( benh khong quan tri hien luat ))*.
