Gufungirwa mu mirima y’inganda bigaragaza kimwe mu bintu bikomeye cyane mu buhinzi bw’amatungo. Muri ibyo bigo, amamiliyari y’inyamaswa abaho ubuzima bwazo bwose mu bice bito ku buryo n’ingendo z’ibanze zidashoboka. Inka zishobora kubohwa mu biraro, ingurube zifungirwa mu dusanduku tw’inda tutarenze imibiri yazo, n’inkoko zigashyirwa mu bikarito by’amabati bigizwe n’ibihumbi. Ubu buryo bwo gufungirwa bugenewe gukora neza no kunguka, ariko bukuraho ubushobozi bw’inyamaswa bwo gukora imyitwarire karemano—nko kuragira, korora ibyari, cyangwa kurera abana bazo—bigahindura ibiremwa bifite ubuzima mo ibice by’umusaruro gusa.
Ingaruka zo gufungirwa muri ubwo buryo zirenze kure imipaka y’umubiri. Inyamaswa zihangana n’ububabare budashira, kwangirika kw’imitsi, no gukomereka biturutse ku bintu byinshi kandi bidafite isuku. Ingaruka zo mu mutwe nazo zirababaje cyane: kutagira ubwisanzure no gukangurwa bitera imihangayiko ikomeye, ubugizi bwa nabi, n’imyitwarire isubiramo kandi isaba imbaraga. Uku kwanga kwigenga mu buryo rusange bigaragaza ikibazo cy’amahame mbwirizamuco—guhitamo uburyo bworoshye bwo mu rwego rw’ubukungu kuruta imibereho myiza y’ibiremwa bifite ubwenge bishobora kubabara.
Guhangana n’ikibazo cyo gufungirwa bisaba uburyo bwinshi. Amavugurura y’amategeko agamije gukumira uburyo bwo gufunga abantu cyane, nk’amasanduku yo gutwita n’aho bategera, yarushijeho gukomera mu turere twinshi, bigaragaza ko hari impinduka mu mikorere irangwa n’ubumuntu. Ariko, impinduka zifatika zishingira no ku bumenyi bw’abaguzi n’inshingano zabo. Mu kwanga ibicuruzwa bikomoka kuri ubwo buryo, abantu bashobora gutuma habaho imyitwarire myiza. Mu kurwanya ubugome busanzwe no gutekereza ku miterere ihesha icyubahiro inyamaswa n’isi, umuryango ushobora gutera intambwe zifatika ugana ahazaza aho impuhwe no gukomeza ubuzima atari ibintu bidasanzwe, ahubwo ari ibipimo ngenderwaho.
Ibisanduku byo gusama ku ngurube ni umuco utavugwaho rumwe cyane mu bworozi bwa kijyambere. Iyi myanya mito, ifunzwe ikoreshwa mu kubamo ingurube, cyangwa kubiba, mugihe batwite. Imyitozo yateje impaka zishingiye ku mibereho y’inyamaswa, kuko akenshi zitera umubabaro mwinshi ku mubiri no mu mutwe ku nyamaswa zirimo. Iyi ngingo irasobanura neza ibisanduku byo gusama aribyo, impamvu bikoreshwa mubuhinzi bwinganda, nibibazo byimyitwarire bazamura. Ibisanduku byo gusama ni iki? Ibisanduku byo gusama, byitwa kandi aho babiba, ni bito, bifungiwe mu cyuma cyangwa insinga zagenewe gufata ingurube zitwite (kubiba) mu buhinzi bw’inganda. Utwo dusanduku twakozwe mu buryo bwihariye kugira ngo tubuze imbuto igihe atwite, bitanga umwanya muto wo gukora imyitozo ngororamubiri. Ubusanzwe gupima uburebure butarenze metero ebyiri z'ubugari na metero zirindwi z'uburebure, igishushanyo ni gito, nkana kubiba umwanya uhagije wo guhagarara cyangwa kubeshya…
