Presents an augmented selection of the material presented at the First Pernambuco Summer School on Software Engineering, PSSE 2004, held in Receife, Brazil in November/December 2004, jointly with the Brazilian Symposium on Formal Methods (SBMF 2004). The main theme in 2004 was re?nement (or rei?cation).
