Perhaps you should try some spelling variations:
dinh luong » dinh duong, dinh huong, dinh quang
dinh cuong » dinh duong, dinh huong
tinh nang » trinh nang, tin nang, tich nang
nang quan » ban quan, nang suat
kiem soat » kiem toan
quan van » luan van, quan luan, quan doan
van hieu » cao hieu
quan va » quan vi, quan ha, luan va
va kiem » van kien

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 nang quan van hieu qua ) OR ( ((dinh luong) OR (dinh cuong)) quan va kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh nang quan van hieu qua ) or ( ((dinh luong) or (dinh cuong)) quan va kiem soat ))*.
