Requirements specification has long been recognized as critical activity in software development processes because of its impact on project risks when poorly performed. A large amount of studies addresses theoretical aspects, propositions of techniques, and recommended practices for Requirements Engineering (RE). To be successful, RE have to ensure that the specified requirements are complete and correct what means that all intents of the stakeholders in a given business context are covered by the requirements and that no unnecessary requirement was introduced. However, the accurate capture the business intents of the stakeholders remains a challenge and it is a major factor of software project failures. This master’s dissertation presents a novel method referred to as “Problem-Based SRS” aiming at improving the quality of the Software Requirements Specification (SRS) in the sense that the stated requirements provide suitable answers to real customer ́s businesses issues. In this approach, the knowledge about the software requirements is constructed from the knowledge about the customer ́s problems. Problem-Based SRS consists in an organization of activities and outcome objects through a process that contains five main steps. It aims at supporting the software requirements engineering team to systematically analyze the business context and specify the software requirements, taking also into account a first glance and vision of the software. The quality aspects of the specifications are evaluated using traceability techniques and axiomatic design principles. The cases studies conducted and presented in this document point out that the proposed method can contribute significantly to improve the software requirements specification.

The State and Public Administration have gone through several reforms in search of a quick operation and the provision of services with quality. With the democratization of the country and the issue of the Constitution in 1988, further reform of the State and Public Administration, joined the government agenda in 1995 and included among its objectives, the principles of participation and social control. In view of this, it raises the Public Ombudsman in order to be a channel for the participation of users in the management of public affairs, social control, transparency of administrative actions, improving the quality of service and meeting the needs of the community. The aim of this study is to assess whether the Ombudsman of the State Department of Public Health to contribute to the period 2006-2008, for the improvement of specialized consulting services. The research is characterized as descriptive, qualitative approach. The collection technique used was the interview, conducted with 37 service users and two servants of the Ombudsman. The analysis was developed based on the perception of users and servers in the opinion of the Ombudsman. The most relevant results of the research showed that 41% of users search the Ombudsman because they believed that solve the problem presented. However, even with this level of public acceptance, the Ombudsman reached average index of resolvability of 53% in the period. In his role has not developed mechanisms for quality control of services, which is mentioned by 67% of users. It turned out the same fact in relation to popular participation, which is confirmed by 84% of users. For 24% of users, the problems raised were resolved, and of these, 56% believe that the Ombudsman has contributed to the positive outcome. As a result of the search results, it appears that the Ombudsman's SESPA / PA, is not fulfilling its role to ensuring the democratization of articipation in management, social control and has limited contribution to solving the problems of users and to improve the quality of services

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Aborda as distorções de representatividade criadas pelo sistema eleitoral brasileiro. Avalia o alcance das proposições legislativas apresentadas depois da edição da Lei Complementar nº 78/1993 até 2006, no sentido de corrigir essas distorções. Conclui que o sistema de lista aberta de voto transferível uninominal brasileiro e a adoção do cálculo de vagas não distribuídas pelo quociente eleitoral incrementam a desproporcionalidade existente. Sugere adoção de fórmula para melhorar a representação política das unidades da federação.
