Actualmente, o SIS depara-se com problemas relativos à normalização e qualidade de dados, interoperabilidade entre instituições e inexistência de sistemas que suportem e agilizem o processo da decisão estratégica no sector. Numa primeira fase, este trabalho caracteriza e clarifica o papel das diversas instituições que colaboram com o MS, a forma como é gerida a informação e o conhecimento e os pressupostos do PNS enquanto documento agregador de indicadores que permitem avaliar o estado da saúde em Portugal. Com base na caracterização do sector e na importância orientadora do PNS, apresenta-se uma metodologia que organiza e desenvolve um modelo de metadados, baseados nos indicadores para a saúde, presentes no PNS. A sua importância para o sector é evidente uma vez que permite servir de suporte ao futuro desenvolvimento de aplicações estratégicas de apoio à decisão, salvaguardando a implementação e a divulgação do PNS e dos seus indicadores. ABSTRACT; Currently, the SIS comes across with problems related with normalization and quality of data, cooperation between institutions and the inexistence of systems that support and speed the process of strategical decisions in the sector. ln a first phase, this work characterizes and simplifies the role of each institution that collaborates with MS, the form as it is managed the information and the knowledge and the fundamentals of PNS, as a document witch aggregates pointers that allow the evaluation of the state of health in Portugal. On the basis of this characterization and the orienting importance of PNS, this work demonstrates a metadata methodology that organizes and develops a model, based on health pointers, indicated in PNS. Its importance for the sector is evident because it can support future developments of strategical applications, safeguarding the implementation and the analysis of PNS and its pointers.

Os Açores reúnem nove ilhas com singularidades peculiares em termos paisagísticos, arquitetónicos e riqueza dos seus recursos naturais. Este panorama levanta contudo grandes desafios de sustentabilidade, de entre eles a reorientação de estratégias, atendendo à especificidade da região (segundo os objetivos à escala nacional em sede da Estratégia Nacional Desenvolvimento Sustentável (ENDS)). No caso da Ilha de Santa Maria (SMA), pequena ilha em que as estratégias tendem a ser ignoradas, a participação da população e dos dirigentes locais é minorada por interesses económicos desvinculados do desenvolvimento sustentável (DS). Para inverter esta situação é necessário conhecer para preservar, proteger para conservar, planificar e orientar os comportamentos e atitudes visando a sustentabilidade dos recursos naturais (RN) da ilha. Aplicando uma metodologia que conjugou os métodos quantitativos e qualitativos, com uma componente prática, utilizando um método de amostragem não casual dirigida, não probabilística com um método de amostragem por clusters, agrupado em grupos (workshop, séniores e jovens), pretendeu-se descrever os conhecimentos, as práticas e as perceções sobre a gestão dos RN’s, DS e instrumentos de gestão territorial (IGT’s). Os resultados mostram que os conhecimentos, práticas e perceções dos diferentes grupos são insuficientes no que respeita ao conhecimento dos conceitos e dimensões do DS (independentemente das idades ou habilitações literárias), verificando-se contudo melhorias, por vezes significativas, após as ações de sensibilização e educação. É imperativo continuar o esforço de valorização dos RN’s, envolvendo a população nas estratégias de conservação, objetivando uma proposta orientadora e participada numa visão para sustentabilidade da Ilha (SMA). Recomenda-se uma proposta de modelo de Estratégia DS dos recursos naturais e biodiversidade para SMA e diversas propostas de ações para colocar em prática essa estratégia como desenvolvimentos futuros.

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres

In this paper we describe the preparation poly (L-lactide) (PLA) nanocapsules as a drug delivery system for the local anesthetic benzocaine. The characterization and in vitro release properties of the system were investigated. The characterization results showed a polydispersity index of 0.14, an average diameter of 190.1± 3 nm, zeta potential of -38.5 mV and an entrapment efficiency of 73%. The release profile of Benzocaine loaded in PLA nanocapsules showed a significant different behavior than that of the pure anesthetic in solution. This study is important to characterize a drug release system using benzocaine for application in pain treatment.

O Serviço de Referência (SR), incorporando na sua organização, funcionamento e comunicação com o utilizador um conjunto de potencialidades proporcionadas pela tecnologia, assume um papel fundamental na luta contra a desigualdade e o analfabetismo digital, no fomento da literacia da informação e na criação de conhecimento. A percepção do valor e das fragilidades do SR nas bibliotecas públicas em Portugal levanta a questão sobre como contribuir para o seu desenvolvimento. A presente investigação, visando a construção de alicerces numa perspectiva de evolução, parte da análise de documentos orientadores internacionais da RUSA/ALA (Reference and User Services Association / American Library Association) e da IFLA (International Federation of Library Association) e da observação de características estruturais da Rede Nacional de Biblioteca Públicas (RNBP), para a concepção de soluções de desenvolvimento do SR a aplicar a esta realidade concreta. Seguindo um paradigma compreensivo indutivo, com uma orientação baseada na Grounded Theory, esta pesquisa privilegia o contexto da descoberta e a construção de uma teoria. No plano empírico cumpre uma complementaridade de técnicas qualitativas e quantitativas, com recurso a uma triangulação metodológica. O campo de análise abrange a totalidade das bibliotecas públicas portuguesas integradas na RNBP em Portugal. Visando aspectos funcionais e materiais, são analisados dados preexistentes e aplicadas técnicas de observação directa e inquérito por questionário. Visando aspectos sociais, são efectuadas seis entrevistas semi-estruturadas. Os resultados apontam para uma situação de estagnação das bibliotecas da RNBP e para um funcionamento não estruturado e informal do SR, na maioria dos casos em que se verifica a sua disponibilização. Fundamentada a necessidade de evolução, e do investimento que nele possa ser feito, é construído um modelo, seguindo uma estratégia por níveis, flexíveis e adaptáveis às necessidades e aos recursos de cada biblioteca, que visa o desenvolvimento incremental e congruente daquele serviço; Abstract: The Reference Service in public libraries in Portugal. Development model from international guidelines. Incorporating in its organization, procedures and communication with the users a set of tools brought by technology, Reference Service (RS) plays a key role in the struggle against inequality and digital illiteracy, promoting information literacy and creating knowledge. The perception of the value of RS and the weaknesses in public libraries in Portugal raise the question on how to contribute to its development. In order to build RS foundations on an evolutionary perspective, this research analyzes RUSA / ALA (Reference and User Services Association / American Library Association) and IFLA (International Federation of Library Association) international guidelines and the structural characteristics of the Portuguese National Public Library Network (RNBP), with the objective of creating a solution for the development of that service to be applied to this reality. Following an inductive comprehensive paradigm, with an orientation based on Grounded Theory, this research focuses on the context of discovery and the construction of a theory. Empirically it fulfils complementary qualitative and quantitative techniques, using a methodological triangulation. The field of analysis covers Portuguese public libraries integrating the RNBP. Aiming at functional and material aspects, direct observation techniques and a survey by questionnaire are applied. Targeting social aspects, six semistructured interviews are carried out. The results point to a situation of stagnation in the RNBP as well as the unstructured and informal performance of the SR, which justifies the need for evolution and investment. A model is constructed, following a strategy based on levels, flexible and adaptable to the needs and resources of each library, with the perspective of an incremental and consistent development of this service.

It seeks to find an alternative to the current tantalum electrolytic capacitors in the market due to its high cost. Niobium is a potential substitute, since both belong to the same group of the periodic table and because of this have many similar physical and chemical properties. Niobium has several technologically important applications, and Brazil has the largest reserves, around 96%. There are including niobium in reserves of tantalite and columbite in Rio Grande do Norte. These electrolytic capacitors have high capacitance specifies, ie they can store high energy in small volumes compared to other types of capacitors. This is the main attraction of this type of capacitor because is growing demand in the production of capacitors with capacitance specifies increasingly high, this because of the miniaturization of various devices such as GPS devices, televisions, computers, phones and many others. The production route of the capacitor was made by powder metallurgy. The initial niobium powder supplied by EEL-USP was first characterized by XRD, SEM, XRF and laser particle size, to then be sieved into three particle size, 200, 400 e 635mesh. The powders were then compacted and sintered at 1350, 1450 and 1550°C using two sintering time 30 and 60min. Sintering is one of the most important parts of the process as it affects properties as porosity and surface cleaning of the samples, which greatly affected the quality of the capacitor. The sintered samples then underwent a process of anodic oxidation, which created a thin film of niobium pentóxido over the whole porous surface of the sample, this film is the dielectric capacitor. The oxidation process variables influence the performance of the film and therefore the capacitor. The samples were characterized by electrical measurements of capacitance, loss factor, ESR, relative density, porosity and surface area. After the characterizations was made an annealing in air ate 260ºC for 60min. After this treatment were made again the electrical measurements. The particle size of powders and sintering affected the porosity and in turn the specific area of the samples. The larger de area of the capacitor, greater is the capacitance. The powder showed the highest capacitance was with the smallest particle size. Higher temperatures and times of sintering caused samples with smaller surface area, but on the other hand the cleaning surface impurities was higher for this cases. So a balance must be made between the gain that is achieved with the cleaning of impurities and the loss with the decreased in specific area. The best results were obtained for the temperature of 1450ºC/60min. The influence of annealing on the loss factor and ESR did not follow a well-defined pattern, because their values increased in some cases and decreased in others. The most interesting results due to heat treatment were with respect to capacitance, which showed an increase for all samples after treatment

The proposal of the present study is to get to know and to analyze the building up of the culture notion among the participants of the Paresi Kozarini group in the ethnodevelopment context. The main focus is the ethnographic study, presenting a description of Aldeia Rio Verde (Paresi Indigenous Land), understanding it as a synthesis of historic processes which explains the current moment of Paresi Indigenous group. By using the mentioned methodology, the processes and social relations produced along the contact path of this group with regional-national culture were focused, and how that contact affects the present. The research questions which concern the present study refer to the processes of identification of the researched subjects about themselves and in relation to others. According as almost the totality of the indigenous group we usually know as Paresi, recognize itself as Kozarini, the attention is directed to the manner how they see themselves and how they differ from the other Paresi groups, not indigenous people, and other indigenous groups; and which meanings of the prefix ethno- (which culture elements) they have elected to represent and manage external matters to their culture and society, in the context of discussions about ethnodevelopment

The study aimed at the treatment of attapulgite for the development and characterization of composite recycled low density polyethylene - PEBD_rec embedded with natural attapulgite - ATP_NAT, sifted - ATP_PN and attapulgite treated with sulfuric acid - ATP_TR in different compositions (1, 3 and 5%) and compared with the PEBD_rec. The atapulgitas, natural, screened and treated, were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), particle size analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and determining the area specific surface (BET). The composites were characterized by thermogravimetry (TG), differential scanning calorimetry (DSC), Xray diffraction (XRD), torque rheometry, scanning electron microscopy (SEM) and traction. The composite PEBD_rec / ATP (natural, sieved and treated) were produced by mixing in the molten state in a single screw extruder matrix wire with subsequent reprocessing matrix tape. It was found that the screening of attapulgite not reduce the quantity of quartz and the acid treatment completely extracted dolomite aggregate impurities of the channels attapulgite, and increase their surface area. The addition of attapulgite in PEBD_rec acts as a catalyst, reducing the thermal stability of the polymer. The increased concentration of attapulgite, increases resistance and reduces the elongation at break and modulus of elasticity of the composite PEBD_rec / attapulgite

O emprego das Forças Armadas Portuguesas em Operações Conjuntas e Combinadas faz-se no âmbito do quadro de alianças de que Portugal faz parte, das quais destacamos a Organização do Tratado do Atlântico Norte. No sentido de melhorar a eficácia operacional, a normalização assume um papel fundamental para que se possa atingir a interoperabilidade entre as forças da Aliança. Assim, este trabalho teve como objetivo principal, analisar e sintetizar os processos de normalização e desenvolvimento de doutrina Militar Conjunta e Combinada nas Forças Armadas Portuguesas. Tem ainda como finalidade, identificar lacunas nos processos nacionais, de forma a contribuir para uma melhor integração e harmonização da doutrina da Aliança, tendo em consideração a doutrina nacional e os interesses nacionais. A nossa investigação baseou-se num raciocínio hipotético-dedutivo, apoiado por uma estratégia qualitativa. O modelo de análise desenvolvido teve por hipóteses, que foram deduzidas de questões derivadas da questão central. Neste processo analítico, identificámos indicadores que permitiram a validação das hipóteses, para este efeito, recorremos a dois estudos de caso e uma análise SWOT. O desenvolvimento de um plano de ação que permita a integração dos processos analisados constitui o principal contributo desta investigação. A necessidade de criar uma Estrutura Coordenadora de Normalização, primordial para agilizar os procedimentos de normalização entre o Ministério da Defesa Nacional, o Estado-Maior General das Forças Armadas e os Ramos, juntamente, com a criação de um Conselho Superior de Doutrina nas Forças Armadas, que defina as prioridades e orientações gerais para o desenvolvimento de doutrina, constituem os principais resultados desta investigação. Abstract: The use of the Portuguese Armed Forces in Combined and Joint Operations is made within the framework of alliances that Portugal is a member, of which we highlight the North Atlantic Treaty Organization. In order to improve the operational efficiency, standardization plays a key role in achieving the interoperability between the forces of the Alliance. The aim of this study is to analyse and synthesize the standardization and development processes of Combined and Joint Military Doctrine in the Portuguese Armed Forces. Identify gaps in national processes, in order to contribute to a better integration and harmonization of the Alliance Doctrine, taking into account the national doctrine and national interests. Our research was based on a hypothetical-deductive argument, supported by a qualitative strategy. The analysis model developed based on assumptions, deducted from derivatives questions of the central question. In this analytical process, we identify indicators that allowed the validation of hypotheses, to achieve this purpose we used two case studies and resort to a SWOT analysis. The development of an action plan that allows the integration of the analysed processes is the main contribution of this research. The need to create a Standardization Coordination Structure it´s crucial to streamline the procedures of normalization between the Ministry of Defence, the Armed Forces General Joint Staff and the Services, along with the establishment of a Doctrine Supreme Council in the Armed Forces, which set the priorities and guidelines for the development of doctrine. This are the main outputs of this research.

Considerada um dos elementos basilares para uma cabal e completa prossecução dos objetivos das instituições, a avaliação de desempenho permite valorizar o elemento distintivo das organizações, o ser humano. É neste contexto holístico, centrado na necessidade objetiva de incrementar o empenhamento organizacional, que a Guarda Nacional Republicana procura, através da aplicação do seu Regulamento de Avaliação de Mérito, avaliar o desempenho dos seus militares, no sentido de verificar em que medida estes contribuem para os fins últimos definidos para a instituição. Deste modo, torna-se evidente a importância de, concomitantemente, investigar de que forma este sistema de avaliação é aceite, interiorizado e percebido pelos militares da instituição e compreender se esse sistema de avaliação se assume como uma mais-valia objetiva na promoção do empenho operacional, permitindo o desenvolvimento da carreira dos mais capazes e orientados para a tarefa institucional. Assim, considerando a unicidade que se encontra adjudicada à categoria profissional de Oficiais, únicos elementos do sistema avaliativo que são, cumulativamente, avaliados e avaliadores, a presente pesquisa, através da aplicação de um questionário a uma amostra de 294 Oficiais, procura saber qual é a representação social que estes têm do sistema de avaliação em vigor na Guarda Nacional Republicana. Abstract: Seen as an essential element for a complete and exact prosecution of the institution’s aims, the evaluation of the performance allows the recognition of the organization’s distinctive element, the human being. It’s in this holistic context, centralized around the objective need to increment the organizational commitment, that the Guarda Nacional Republicana tries to evaluate the performance of its militaries, through the application of its Merit Assessment Regulations, as a manner of verifying the way these contribute to the defined aims of the institution. Therefore, it is of evident importance the investigation that, concomitantly, analyses how the evaluation system is accepted, interiorized and understood by the militaries of the institution, along with understanding how much that same evaluation system comes as an objective advantage on the promotion of the operational performance, allowing the development of the career of the more capable and guided for the institutional mission. According to this, and considering the unity that is adjudicated to the professional category of Officials, the only elements of the evaluation system that are both evaluated and evaluators, this research, through the use of a set of questions made to a sample of 294 Officials, tries to discover the social representation that they have of the evaluation system that is now applied in the Guarda Nacional Republicana.
