OSB tsom mus rau kev soj ntsuam nruj ntawm cov khoom siv thiab cov khoom zoo.

Ua ntej thiab qhov tseem ceeb tshaj plaws, peb nruj me ntsis xaiv thiab lees paub cov chaw muag khoom ntawm cov khoom siv raw thiab cov khoom kom ntseeg tau tias lawv cov khoom tau raws li peb cov kev xav tau zoo. Peb ua qhov tseem ceeb rau cov neeg muag khoom nrog lub koob npe nrov thiab kev paub dhau los hauv kev lag luam, vim tias lawv tuaj yeem muab cov ntaub ntawv zoo thiab ua kom cov khoom xa tuaj raws sijhawm.

Qhov thib ob, peb tau tsim cov txheej txheem tshuaj xyuas cov khoom thiab cov txheej txheem nruj heev. Ua ntej cov ntaub ntawv tuaj txog ntawm peb lub Hoobkas, peb pab neeg tswj xyuas zoo ua kev tshuaj xyuas ntawm txhua pawg ntawm cov khoom. Qhov no suav nrog kev kuaj xyuas qhov zoo, tsim qauv, teeb tsa thiab lwm yam. Tsuas yog tom qab dhau peb qhov kev tshuaj ntsuam xyuas kom meej cov ntaub ntawv tuaj yeem mus rau theem tsim khoom. Rau cov ntaub ntawv uas tsis ua raws li peb cov qauv, peb tam sim ntawd sib txuas lus nrog cov neeg muag khoom los thov kev hloov kho lossis nrhiav lwm tus neeg muab khoom tsim nyog.

Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntau lawm, peb ua sampling kev soj ntsuam thiab xyuas tsis tu ncua kom ntseeg tau tias zoo ib yam. Peb hais txog kev cob qhia cov neeg ua haujlwm los pab lawv nrog kev paub ntau lawm thiab kev xav zoo, kom ntseeg tau tias txhua yam ua raws li peb cov kev xav tau zoo.

Los ntawm cov kev tswj xyuas cov khoom lag luam zoo zoo no, peb muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov ntaub ntawv raw, ua rau peb muab peb cov neeg siv khoom nrog cov khoom siv zoo tshaj plaws. Peb lub hom phiaj yog los tsim peb lub tuam txhab cov duab kos thiab tau txais cov neeg siv khoom kev ntseeg siab thiab kev txhawb nqa los ntawm kev ua raws li kev tswj hwm nruj.
