Nyuma yo kugenzura no kugerageza ibikoresho bizengurutswe ibyuma, umusaruro urashobora gutangira ukurikije ubunini bwumupira wibyuma. Guhimba ibyuma bishyushya ubushyuhe runaka muguhuza itanura ryinshyi kugirango habeho ibisekuruza bikora neza mubihimbano; Icyuma gitukura-gishyushye cyoherezwa mu nyundo yo mu kirere kandi gitunganywa nabakora ubuhanga. Nyuma yo guhimba umupira wicyuma utukura uhita winjira muri JUNDA ibikoresho byabugenewe byo gutunganya ubushyuhe bwo kuzimya no kugabanya ubushyuhe, agaciro gakomeye kandi kamwe k’umupira wibyuma karashobora kwizerwa.
