thank you Ryan

anyway, a friend of mine, cristian (zany) zaninovic, gently answer me, 
he spoke as: hey bastard, you should use :

paramA = 'year'
paramB = 'month'
dateFieldName = 'name_of_da_field'
@activityPeriods = coleccion.map{ |x| 
[eval("x.#{dateFieldName}.#{paramA}"), 
eval("x.#{dateFieldName}.#{paramB}")] }.uniq

I didn't try already, but think it will work
