In this article we defend the idea that social aspects have strong influence in the software requirements elicitation (Goguen 1993), which drive us to find help in the social sciences. The Activity Theory is a theory developed in the Psychology that focuses the human practices of development process, both the individual and social levels. This theory states(More)
The projects with embedded systems are used for many different purposes, being a major challenge for the community of developers of such systems. As we benefit from technological advances the complexity of designing an embedded system increases significantly. This paper presents GERSE, a guideline to requirements elicitation for embedded systems. Despite of(More)
This paper presents a template for environmental requirements specification in embedded systems, called TERASE. There is a lack of requirements specification templates that address the particularities of the embedded systems development. With TERASE embedded system engineers can improve their environmental requirements specification, as well as the(More)
The requirements engineers use several techniques to assist them on the elicitation, analysis, specification, validation and requirements management process, but the number of those tools in this segment is still reduced. The requirements are the base for the software development, which, most of time is described in natural language. In this paper a tool(More)
Resumo. O objetivo deste trabalho é apresentar uma proposta de organização do processo de elicitação de requisitos através do conceito de atividade. Para isso, apresentamos uma metodologia de elicitação de requisitos centrada neste conceito. O conceito de atividade é extraído da Teoria da Atividade, uma teoria da área da Psicologia, que estuda a formação(More)
This study analyzed the genotype distribution and frequency of lamivudine (LAM) and tenofovir (TDF) resistance mutations in a group of patients co-infected with HIV and hepatitis B virus (HBV). A cross-sectional study of 847 patients with HIV was conducted. Patients provided blood samples for HBsAg detection. The load of HBV was determined using an(More)
