Uyilo lwangaphakathi o ukulungiswa ngaphakathi (ngamanye amaxesha etyunjwe ngumxube: ukulungiswa ngaphakathi okanye iAnglicism: ukulungiswa ngaphakathiUyilo lwezithuba kunye nezinto ezisetyenziswa rhoqo kwiindawo ezivaliweyo, ezinje ngamakhaya abucala, iinkampani, iindawo zokwamkela kunye neendawo zokusebenza.
Abaqulunqi bangaphakathi bahlala benxulunyaniswa nabalinganiswa abafana ngakumbi noonobumba bangaphakathi, kodwa enyanisweni, abayili banika ingqalelo ekhethekileyo ekusebenzeni nasekusebenzeni kwendawo yokuhlala. Umzekelo, ukuba ubungakanani bekhabhinethi bufanelekile, ukuba kukho indlela.
Hlonipha indawo, cwangcisa ifanitshala ngendlela etofotofo nesebenzayo, funda izixhobo ezikumgangatho ophezulu kunye netekhnoloji engayi kubonisa isoyikiso kwimpilo yabantu abaya kusebenzisa ezi ndawo, baphelise izithintelo zokwakha, benze uhlengahlengiso lolwakhiwo kunye nolwakhiwo lwanamhlanje ukufumana usetyenziso olutsha lwesakhiwo.
Ukufezekisa isiphumo esihle sokugquma isandi, ubudlelwane obulungileyo phakathi kokusetyenziswa kwamandla kunye nentuthuzelo, imeko-bume iphela kufuneka igcine ukuvumelana phakathi kobungakanani bendawo yonke kunye nokusetyenziswa kwento engenanto.
Kule minyaka ilishumi idlulileyo, inaniukulungiswa ngaphakathi badlale indima ebalulekileyo kulwakhiwo lwezakhiwo zikawonke-wonke okanye ezabucala ukuba iikhosi eziyunivesithi zokwenyani zazalwa kwiiyunivesithi ezininzi zase-Italiya (ezinje nge Ipolitecnico di Milano).
Phambi kokungeniswa kwezi nkcazo, zonke ezi zinto zinokulandelwa kubugcisa bokuhombisa, obahlukileyo kubugcisa bokwakha kuba abuguquli ubume bokuthwala besakhiwo, kodwa bujongana nokuhonjiswa kwangaphakathi nangaphandle kunye nempahla yokwenene.
Kufuneka kukhunjulwe ukuba igama "uyilo" yaziswa kutshanje, isuka kwisiNgesi embindini we-1900s, kwaye ihlala ichazwa ngokwakhiwa kwetayitile, ukuzoba okanye ukucwangcisa.
