Dear reader, this issue of Revista Ingenierías Universidad de Medellín delivers 14 articles, 6 of which are in English, in accordance with the internationalisation goal necessary for delivering our content to the non-Spanish speaking public of our journal. This is why we have decided that since July of this ongoing year, every article received and approved for publication will circulate in English. This represents a series of challenges for all of the people that are part of this journal: authors, evaluators, the editorial committee, the University of Medellin collaborators; which demands from us breaking the country's endogamy and including into our published contents more international works and researches, which requires a high-quality joint work among institutions and researchers that allows us to increase the impact and visibility of our journal and the contents we deliver to our public with the clear purpose of belonging and being visible in high impact international data.
We thank those who in one way or another accompany us and make possible our continuous growth and projection. We invite you to assume this challenge with us in order to deliver ever more relevant contents for the international public
