No. of bitstreams: 1 Walquiria Barcelos de Figueiredo.pdf: 11234029 bytes, checksum: dbf21e923a2bfae3e29f6be02048db53 (MD5) Previous issue date: 2014-11-19 / The present study aimed to point out the reasons of failure of supply of inputs to an Intensive Care Unit (ICU) of a tertiary public hospital, identifying the risks associated with lack of essential materials in patient care and the occurrence of Healthcare Associated Infection (HAI). For this purpose, a study delineated as action research was conducted, as well as surveys and document analysis of recorded cases of HAI in the studied unit between 2012 and 2013, apart from the content analysis of the spreadsheet input supply. A literature search was conducted on standards, legislation and scientific articles related to the subject. Aiming to understand the perception of the professional group, a survey instrument was applied to the staff of the unit in a form of a semi-structured questionnaire. Through opportunities for improvement related to the management and control of essential materials, care of patients, a scoring model to material considered essential to the ICU, based on the classification system into categories ABC and XYZ was proposed. According to the criticality of the missing material to be used in sector, it was possible to generate a report to the Sub Committee on Hospital Infection Control and the administrative sector, to help in emergency procurement and distribution of basic materials for the assistance and thus minimize the occurrence of adverse events and consequently increased professional satisfaction and patient safety. / O presente estudo objetivou levantar quais as razões das falhas de abastecimento dos insumos de uma Unidade de Terapia Intensiva (UTI) de um hospital público terciário, identificando os riscos associados à falta de materiais essenciais na assistência ao paciente e na ocorrência de infecções relacionadas à saúde (IRAS). Para isso, foi realizado um estudo delineado como pesquisa-ação, além de levantamentos e análise documental dos casos registrados de IRAS na unidade entre 2012 e 2013, bem como análise de conteúdo das planilhas de fornecimento de insumos. Uma pesquisa bibliográfica também foi realizada, sobre normas, legislações e artigos científicos relacionados ao assunto. Com o objetivo de compreender a percepção do grupo profissional, um instrumento de pesquisa foi aplicado na forma de questionário semiestruturado à equipe da unidade estudada. Através das oportunidades de melhoria relacionadas à gestão e controle de materiais essenciais para o cuidado de pacientes, foi proposto um modelo de pontuação a esses materiais considerados fundamentais para a UTI, baseado no sistema de classificação em categorias ABC e XYZ. De acordo com a criticidade do material em falta a ser utilizado no setor, foi possível gerar um relatório à Subcomissão de Controle de Infecção Hospitalar e ao setor administrativo, para auxiliar na aquisição emergencial e distribuição dos materiais básicos para a assistência, e desta forma minimizar a ocorrência de eventos adversos e aumentar, consequentemente, a satisfação dos profissionais e segurança dos pacientes.

A expressão agronegócio (agribusiness) originou-se na Universidade de Harvard na School of Business Administration, em 1957, com a publicação do livro A Concept of Agribusiness, de John Davis e Ray Goldberg. A ideia do agronegócio resulta em uma cadeia produtiva, com vários elos bastante interdependentes, das fases de produção até a comercialização do produto final O Brasil é visto por especialistas como um potencial fornecedor de alimentos global. E assim, a manutenção e o crescimento da participação produtiva do setor agrícola e pecuário nacional dependem de questões relacionadas à tecnologia. A problemática do trabalho envolve questões da diferenciação entre agropecuária e agronegócio. As fontes de referências de dados trazem informações, mas não englobam atividades da pré-produção, por isso, procurou-se responder: Não seria mais apropriado acrescentar a esta balança comercial os setores para trás, já que se trata como agronegócio? O objetivo é analisar por outra perspectiva os dados da balança comercial do agronegócio, propondo a adição de insumos intrínsecos aos produtos agropecuários, sob a ótica das intensidades tecnológicas, analisando seu comportamento no período de 1997 a 2017, permitindo assim, discorrer sobre o desempenho dos principais grupos de produtos da pauta de exportação e importação desse setor que serve de alicerce para a economia brasileira. Os resultados apontaram para fez diferença em termos de contribuição para a balança comercial do agronegócio a inclusão dos grupos de produtos peixes e crustáceos; produtos farmacêuticos; adubos (fertilizantes); e tratores na nova proposta a contribuição para a balança comercial total é menor. Ademais, os dados mostraram que o país tem dependência externa das vacinas e dos adubos e que esses produtos são de alta e média-alta intensidade tecnológica. / The term agribusiness originated at Harvard University at the School of Business Administration in 1957 with the publication of A Concept of Agribusiness by John Davis and Ray Goldberg. The idea of agribusiness results in a productive chain, with several interdependent links, from the production phases to the commercialization of the final product. Brazil is seen by experts as a potential global food supplier. The maintenance and growth of the productive participation of the national agricultural and livestock sector depends on issues related to technology. The problem of this papers involves issues of differentiation between agriculture and agribusiness. The sources of data references provide information, but do not include pre-production activities, so we tried to answer: Would it not be more appropriate to add the input sector to this trade balance, since it is called as agribusiness? The objective is to analyze from another perspective the agribusiness trade balance data, proposing the addition of intrinsic inputs to agricultural products, from the perspective of technological intensities, analyzing their behavior in the period from 1997 to 2017, thus allowing a discussion on the performance of the agribusinesses. main product groups of the export and import tariff of this sector that serves as a foundation for the Brazilian economy. The results pointed to the difference in terms of the contribution to the agribusiness trade balance to include the fish and crustaceans product groups; pharmaceutical products; fertilizers; and tractors in the new proposal the contribution to the total trade balance is lower. In addition, the data showed that the country has external dependence on vaccines and fertilizers and that these products are high and medium-high technological intensity.

Tato práce se zabývá úlohou odhadování prostorové funkce z hlediska regrese pomocí Gaussovských procesů (GPR) za současné nejistoty tréninkových pozic (pozic senzorů). Nejdříve je zde popsána teorie v pozadí GPR metody pracující se známými tréninkovými pozicemi. Tato teorie je poté aplikována při odvození výrazů prediktivní distribuce GPR v testovací pozici při uvážení nejistoty tréninkových pozic. Kvůli absenci analytického řešení těchto výrazů byly výrazy aproximovány pomocí metody Monte Carlo. U odvozené metody bylo demonstrováno zlepšení kvality odhadu prostorové funkce oproti standardnímu použití GPR metody a také oproti zjednodušenému řešení uvedenému v literatuře. Dále se práce zabývá možností použití metody GPR s nejistými tréninkovými pozicemi v~kombinaci s výrazy s dostupným analytickým řešením. Ukazuje se, že k dosažení těchto výrazů je třeba zavést značné předpoklady, což má od počátku za následek nepřesnost prediktivní distribuce. Také se ukazuje, že výsledná metoda používá standardní výrazy GPR v~kombinaci s upravenou kovarianční funkcí. Simulace dokazují, že tato metoda produkuje velmi podobné odhady jako základní GPR metoda uvažující známé tréninkové pozice. Na druhou stranu prediktivní variance (nejistota odhadu) je u této metody zvýšena, což je žádaný efekt uvážení nejistoty tréninkových pozic.

This thesis focuses on design and implementation of a tool for automated generation of test inputs for a specified program trace. The aim of the thesis is to make development of testing suites (complying a given advanced coverage criteria) easier and more effective. These kinds of test suites are used in critical applications with code base written in low-level languages like C/C++ with strict restrictions applied. The tool investigates a program model and what conditions must be met to execute program in a way following provided trace. The tool uses advanced SMT-solver tool (software tool specialized for solving satisfiability problem) for generating fitting values. LLVM compiler framework libraries are used for modelling a program. Z3 library is used as a SMT-solver backend. This thesis brings results in architectural and implementation design of a tool capable of test inputs generation based on program analysis and provided program trace to cover.

In this thesis we study a novel approach to on-line learning of artificial neural networks, called backward modelling, and apply it to active learning in the sensorimotor loop. At first the mathematic foundations of this approach are elaborated. We observe effects like spontaneous symmetry breaking, response increasing, and generalisation improvement at a theoretical level. We then justify the theory with experimental results on some synthetic problems, in order to understand the phenomena clearly. Finally we consider a simple robot with an adaptive world model. In the case the controller of the robot is just covering a sub-space of the actuator space we realise degenerated world representations in the world model with passive learning and standard learning algorithms. We show that backward modelling and active learning point out degeneracies in the world model and correct them with direct exploration. A special kind of active learning evolves from the use of backward modelling which directly queries patterns on the fly. Additionally, different strategies are investigated in order to control the interplay of controller based and active learning based behaviour.
