Umwirondoro w'Ikirango Cristaderm, ikirango cy'ubuvuzi bw'uruhu kiva muri Koreya, gihuza udushya mu bya siyansi n'ibishushanyo byimbitse. Kibitswe n'imiterere y'ADN yomboze kabiri, umwirondoro wacyo ugaragara urimo ibishushanyo bya molekule igoye hamwe n'inyuguti z'ikoreya, bigatera ubwiza butunganijwe. Ikirango, gifite imyandikire isukuye hamwe n'ishusho ya parallelogramu, cyerekana umusozo n'ubuhanga. Sisitemu y'ibimenyetso ihuza imiterere ya molekule za chimique hamwe n'inyuguti z'ikoreya, yongera ubujyakuzimu mu muco n'ubwenge. Ubu bushushanyo bwatejwe neza bureba neza ko ishusho rya Cristaderm rikora neza kandi rishimisha amaso, rishyiraho igipimo gishya mu buvuzi bw'uruhu.

Izina ry'umushinga : Cristaderm, Izina ryabashushanya : Wai Ho Cheung, Izina ry'abakiriya : Cristaderm.

Rimwe na rimwe, ukenera itsinda rinini cyane ryabashushanyije bafite impano kugirango bazane ibishushanyo byiza rwose. Buri munsi, turagaragaza ibihembo byihariye byatsindiye udushya no guhanga udushya. Shakisha kandi uvumbure imyubakire yumwimerere kandi irema, igishushanyo cyiza, imyambarire, igishushanyo mbonera nigishushanyo mbonera cyimishinga yaturutse mumakipe ashushanya isi yose. Shishikarizwa nibikorwa byumwimerere nabashushanyo bakomeye.
