The IFRO is a B azilian Public Ins i u ion o echnical and

The SEI was de eloped by he Regional Elec o al Cou o he

The SEI has been used by IFRO e ec i ely since 2017,

Da is e al (1989) p oposed he echnology accep ance model
(TAM). The objec i e o his model is o e alua e he accep ance

CONCLUSIONS
