This thesis deals with analyzing the contribution grade of the ISO 9000 quality system to the strategic performance of the Brazilian firms in the Chemistry sector, using the Balanced Scorecard system as reference. An exploratory research is developed to get technical information about these two management systems, with emphasis in their integration. After, a quantitative research is implemented using a questionnaire, to know and to obtain necessaries data for improving statistical estimations of the multiple relationships between the variables and the strategic performance for the universe of 352 Brazilians firms that make use of ISO 9000 as quality system. The size of the sample totalized 111 firms, which represent more than 31% of the selected universe. The main results show different visions of directors and managers about the significant variables that contribute for the strategic performance of the analyzed firms. The ISO 9000 system presents a big contribution to the strategic performance, when referred by the four perspectives of the Balanced Scorecard: learning and growth; internal process; customer and financial. Better performance was verified in the learning and growth perspective and reasonable performance was verified in the financial perspective

The public sector performance has received much attention in the literature and due to that the purpose of this work is to develop a proposal for a model of performance measurement for a higher education institution unit. First, we performed a theoretical research on public organizations and private institutions of higher education, followed by a literature review on performance measurement and evaluation. This review presents some performance models that are quite frequent in the literature: Total Quality Management (Total Quality Management) - TQM and the PDCA cycle, SMART System, Balanced Scorecard and Môdef Ouanturn. In order to verify the possibility of implementing a performance measurement model for Higher Education Institutions, it was conducted a case study in a support unit of a University, located in the city of Natal, RN, Brazil. The study attempted to identify the key processes of the unit and proposed by the use of Quantum model in order to improve the management and operation of the same. The work aims to contribute to the advancement of knowledge in measurement and performance evaluation in higher education institutions that where still lacks scientific production of this subject compared to other areas. This study also identifies better practices and opportunities for improvement in processes to determine the expected performance indicators to aid a decision-making unit.

This Thesis deals with the performance improvement on hotels that have adopted the ISO 9000 Quality Management Systems. It is researched the Brazilian hotels that have an ISO 9001 registration with an assessment form based on the Balanced Scorecard approach. The main findings are that ISO 9000 provided improvement on the performance of the hotels in general and also in all the BSC perspectives, and that are different perception on managers and directors, what suggests a need for a tool like BSC to register the performance improvements on the same basis. The Thesis contributes to provide information on the performance improvement in hotels, one of the claimed regarding the low ISO 9000 adoption rate in Brazilian hotels

The use of increasingly complex software applications is demanding greater investment in the development of such systems to ensure applications with better quality. Therefore, new techniques are being used in Software Engineering, thus making the development process more effective. Among these new approaches, we highlight Formal Methods, which use formal languages that are strongly based on mathematics and have a well-defined semantics and syntax. One of these languages is Circus, which can be used to model concurrent systems. It was developed from the union of concepts from two other specification languages: Z, which specifies systems with complex data, and CSP, which is normally used to model concurrent systems. Circus has an associated refinement calculus, which can be used to develop software in a precise and stepwise fashion. Each step is justified by the application of a refinement law (possibly with the discharge of proof obligations). Sometimes, the same laws can be applied in the same manner in different developments or even in different parts of a single development. A strategy to optimize this calculus is to formalise these application as a refinement tactic, which can then be used as a single transformation rule. CRefine was developed to support the Circus refinement calculus. However, before the work presented here, it did not provide support for refinement tactics. The aim of this work is to provide tool support for refinement tactics. For that, we develop a new module in CRefine, which automates the process of defining and applying refinement tactics that are formalised in the tactic language ArcAngelC. Finally, we validate the extension by applying the new module in a case study, which used the refinement tactics in a refinement strategy for verification of SPARK Ada implementations of control systems. In this work, we apply our module in the first two phases of this strategy

Esta revisão teve por objetivo destacar os principais achados publicados nos últimos dez anos sobre os efeitos da respiração frenolabial (RFL) em pacientes com doença pulmonar obstrutiva crônica (DPOC). A busca dos artigos foi realizada nas bases de dados Lilacs, IBECS, MEDLINE e SciELO, por meio dos seguintes descritores da área da saúde (DeCS): doença pulmonar obstrutiva crônica, reabilitação, respiração, hiperinsuflação e dispneia, e suas respectivas versões na língua inglesa (MeSH), além do termo pursed-lip breathing. Após a eliminação dos títulos repetidos, foram selecionados somente os estudos que abordavam a RFL como tema principal, resultando em 12 artigos científicos, 10 ensaios clínicos e 2 revisões bibliográficas. Segundo os achados, a RFL proporciona: alterações sobre a gasometria arterial, caracterizada pelo aumento da saturação e pressão parcial de oxigênio; padrão ventilatório, com diminuição da frequência respiratória e aumento de tempo expiratório e do volume corrente; mecânica ventilatória, por meio do recrutamento de musculatura abdominal expiratória e dos músculos da caixa torácica e acessórios da inspiração; diminuição no consumo de oxigênio; alterações na modulação autonômica cardíaca induzida pelo aumento da atividade parassimpática e, por fim, melhora na qualidade de vida destes pacientes. A RFL é considerada uma manobra de grande importância, por repercutir de forma positiva em diversos sistemas e sobre a qualidade de vida de pacientes portadores da DPOC.

A literatura sugere que o Seis Sigma trouxe contribuições sob vários aspectos, tanto no âmbito da gestão da qualidade como também da gestão estratégica. No entanto, ainda há certa escassez de informações sobre esse assunto no cenário organizacional brasileiro. Este artigo visa reduzir essa carência da literatura, mostrando uma visão prática sobre as contribuições decorrentes dos investimentos no Seis Sigma para empresas do Brasil. A relevância de requisitos essenciais - como conceito de qualidade; combinação das abordagens estatística e estratégica; sistematização metodológica; formação de especialistas; e gestão de projetos - é discutida tanto em âmbito teórico-conceitual como prático. O método do estudo de caso foi aplicado para obter o embasamento empírico da pesquisa. Os investimentos no Seis Sigma feitos por duas subsidiárias brasileiras de empresas multinacionais norte-americanas (uma de manufatura e uma de serviços) são apresentados e reforçam a relevância dos requisitos supracitados.
