Kuita maekisesaizi nguva dzose kunoratidzwa sekiyi yekurarama hupenyu hurefu uye hune hutano. Asi zvidzidzo zvishomanana zvakapinda mukuenzanisa mukurarama kwenguva refu pakati pevaya vanoita basa rakasimba rekuita uye avo vanonyanya kurarama mararamiro ehupenyu semugumisiro wehupenyu hwavo hwose.
Zvino, Naoyuki Hayashi naKazuhiro Kezuka vanobva kuTokyo Tech's Institute of Liberal Arts vakaita. Chidzidzo zvisina kujairika zvinopokana nepfungwa yekuti kurovedza muviri kwakasimba kwezuva nezuva kwakabatana nehupenyu hurefu.

Vaifungidzira kuti vatambi vekabuki vaizorarama hupenyu hurefu nekuda kwehuwandu hwekuita kwemuviri kunobatanidzwa mumatambo avo emitambo, zvichienzaniswa nevarapi veSado, Rakugo uye Nagauta, vanozivikanwa nekuita mhemberero dzetii, vachitaura nyaya dzinosetsa uye kutamba zviridzwa zvemimhanzi vakagara, zvichiteerana.
Kurovedzera muviri kwakanyanya hakureve hazvo hupenyu hurefu
Nekuongorora ruzivo rwehupenyu hurefu kubva kunyanzvi dzechinyakare dzechiJapan, vaongorori veTokyo Institute of Technology (Tokyo Tech) vakawana kuti vatambi vekabuki, vanozivikanwa nekufamba kwakasimba, vaive nehupenyu hupfupi zvinoshamisa kana vachienzaniswa nemamwe maartist echinyakare. Zvigumisiro zvinoratidza izvozvo kurovedza muviri kwakasimba kunoenderana nebasa muhupenyu hwese hakurebe hazvo hupenyu hurefu.
Kushandisa nzira inonzi Kaplan-Meier ongororo, yakawana kuti, zvinopesana nezvaitarisirwa, hupenyu hwevatambi vekabuki hwakanga hupfupi pane hwemamwe marudzi matatu evatambi vetsika.
Vatsvakurudzi vanofungidzira kuti chimwe chikonzero chehupenyu hupfupi hwevatambi ve kabuki inogona kunge iri iyo kudzidziswa kwakanyanyisa kuramba uye kurovedza muviri kunokurira mativi anobetsera okurovedza muviri nguva dzose. Chimwe chikonzero chingave chekuti munguva yakapfuura, kabuki vatambi vaiwanzoshandiswa oshiroi (poda chena inoshandiswa cheno) ine lead, iyo inotakura njodzi huru yehutano. Kushandiswa kwe oshiroi kwakangorambidzwa muJapan muna 1934.
Vatsvagiri vanocherekedza kuti kudzidza kwavo hakuna pasina miganhu. Semuyenzaniso, iyo data yaingotarisa pamabasa anotongwa nevarume uye saka haipe pfungwa yehupenyu hurefu hwehuwandu hwese, kusanganisira vakadzi. Basa rakawanda raizodiwa kuongorora huwandu hwakakwana hwekurovedza muviri kuchengetedza hutano. Zvingangove zvinobatsira zvezviitwa zve'kusaita maekisesaizi' zvakaita sekutaura, kuimba uye kuridza zviridzwa zvingadawo kumwe kuongorora.
Pakazara, vaongorori vanoti kudzidza kwavo kunomiririra "nzira itsva yekutora ruzivo kubva kune veruzhinji data»Uye«inobatsira kune maitiro epasi rose ekugadzirisa kuberekana mune sainzi".
