A total of 480 students were surveyed during
the five years period, each one accounting for
different weights (varying from 35.2 in 2007, to
8.3 in 2010). Additionally, not all the respondents
answer the questions posed, being curiously gender
the one that created more discomfort. In the end,
approximately 56.9% of the students were female,
15.6% had more than 30 years, and 52.1% had
professional experience (Table 2).
