When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. The influence of choosing the right amount of each material lies in the unit-price of the different material, where they can differ significantly. The Swedish Transport Administration, Trafikverket, has ordered the construction of Stockholm Bypass which is one of Swedens largest infrastructure project and is valued to 27.6 billion SEK according to the price index of the year 2009. The infrastructure project is divided into multiple projects where one of them is assigned to Implenia and Veidekke through a joint venture (Joint venture Hjulsta, JVH) and is valued to nearly 800 MSEK. The reference bridge that is used in the analysis of the master’s thesis is a part of the project. The aim of this masters thesis was to analyze and compare the two construction methods, mov- able scaffolding system (MSS) and incremental launching for the reference bridge with respect to amount post-tensioning and slenderness. Furthermore, an economical comparison between the two construction methods was carried out based on the obtained results. The analysis of the MSS was carried out by modeling the reference bridge structure in the finite element software SOFiSTiK AG. The bridge was modeled with different cross section height, i.e. different slenderness where the optimal amount of post-tension tendons could be determined by iteration until stress conditions from the Eurocode were fulfilled. For the incremental launching method, a numerical analysis was performed. The optimal amount of required post-tensioning was evaluated in the construction stages and final stages with different construction heights i.e. different values of slenderness. A cost analysis was also performed where the aim was to analyze how the total cost of the construc- tion of the bridge would be influenced by the different slenderness of the bridge as a comparison for the two construction methods. This was done by dividing the costs into fixed costs and variable costs. The results showed that the structural rigidity had a large influence on the required amount of prestressing steel for both construction methods. In other words, the smaller the cross section the more prestressing steel was required. Incremental launching proved to require a much greater amount of (PT) tendons compared to the MSS although the identical cross sections and properties for both methods, except for the PT. The prestressing for incremental launching is generally by centrical prestressing during the construction stages. A intersection point was obtained in the cost analysis for the construction methods. The incremental launching was the cheaper solution for slenderness smaller than the intersection point at slenderness between 17 and 18. The MSS was cheaper than the incremental launching for slenderness larger than the intersection point. / Vid dimensionering av tvärsektioner i broar är det av stor vikt att optimera geometrin avseende materialåtgång då mängden material har stor på verkan på ett projekts budget samt miljö. Eftersom konstruktioner ofta består av olika byggnadsmaterial gäller det vid optimering att välja byggnadsmaterialen genom optimerad proportionalitet. Förbifart Stockholm, beställt av Trafikverket, är ett av Sveriges största infrastrukturprojekt och värderas till 27,6 miljarder kronor enligt 2009 års prisnivå. Infrastrukturprojektet är uppdelat i flera mindre entreprenader eller så kallade etapper. Den entreprenad som omfattar trafikplats Hjulsta Södra har blivit tilldelat till Implenia och Veidekke genom ett konsortium (Jointventure Hjulsta, JVH) och värderas till cirka 800 miljoner kronor. Den förspända betongbro som byggs i trafikplats Hjulsta ligger till grund för analysen i detta examensarbete och har använts som referens under vår studie. Syftet med examensarbete var att analysera och jämföra två de två olika produktionsmetoderna, Movable scaffolding system (MSS) och etappvis lansering med hänsyn till erforderlig mängd förspänningskablar och slankhet. Vidare, baserat på erhållna resultat, utfördes en ekonomisk analys och jämförelse mellan produktionsmetoderna. Analysen av MSS utfördes genom att modellera brokonstruktionen i mjukvaruprogrammet SOFiSTiK AG som bygger på finita elementmetoder. Konstruktionen modellerades för olika slankheter, där slankheten definieras som kvoten mellan maximala spannlängden och brons tvärsnittshöjd. Spannlängden hölls konstant medan tvärsnittshöjden varierade för att erhålla olika slankheter. Den optimala slankheten bestämdes genom iterering av mängd förspänningskablar tills spänningsvillkoren var uppfyllda enligt Eurocode. För analysen av etappvis lansering utfördes en numerisk analys vars den optimala mängden förspänningskablar utvärderades i byggskedet (construction stages) samt i slutskedet (final stage). Analysen utfördes på samma sätt för de olika slankheterna. Slutligen genomfördes en konstandsanalys för de olika metoderna. Syftet var att jämföra hur den totala kostnaden för uppförandet av brokonstruktionen skiljde sig för de olika slankheterna. Jämförelsen genomfördes genom att dela upp de olika kostnaderna i fasta kostnader samt rörliga kostnader. Resultaten från analysen visade att den erforderliga mängd förspänningskablar som behövs i en förspänd betongbro är beroende av den strukturella styvheten i tvärsektionen. En högre slankhet, alltså lägre tvärsnittshöjd, ger lägre styvhet och därav mer erforderlig förspänningskablar. Etappvis lansering visade sig vara den metod som krävde mer mängd förspänningskablar. I resultaten för kostnadsanalysen uppmättes en skärningspunkt, för en slankhet mellan 17-18, mellan de två olika metoderna. För förspända betongbroar med slankhet lägre än skärningsupunkten vid 17-18 är etappvis lansering det billigare alternativet. För slankheter högre än 17-18 är MSS det mer ekonomiskt lönsamma alternativet.

Thesis (LLM)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Inaedificatio entails that movables that have been permanently attached to land through building cease to exist as independent things and become part of the land. Courts have adopted different approaches over time to investigate whether or not inaedificatio had occurred. It is sometimes said that courts have moved away from the so-called traditional approach, which focused on the objective factors, to the so-called new approach, which places more emphasis on the subjective intention of the owner of the movables. This thesis analyses the applicable case law and concludes that there is inadequate proof of such a shift since both older cases associated with the traditional approach and later cases associated with the new approach emphasise the intention of the owner of the movables to establish whether accession had taken place. However, the case law does allow for a cautious different conclusion, namely that a certain line of both older and new cases emphasise the owner of the movable’s intention for commercial policy reasons, specifically to protect ownership of the movables in cases where ownership had been reserved in a credit sale contract. Constitutional analysis of these conclusions in view of the FNB methodology indicates that the courts’ decision to hold that accession had in fact occurred in cases that do involve permanent attachment of movables to land will generally establish deprivation of property for purposes of section 25(1) of the Constitution, but such deprivation would generally not be arbitrary since there would be sufficient reason for it. However, in cases where the courts decide that there was no accession because ownership of the movables had been reserved subject to a credit sale agreement, there is no deprivation of property because the landowner, who is the only one who might complain about the decision, could not prove a property interest for purposes of section 25(1). Moreover, the courts’ decision that accession had either occurred or not does not amount to expropriation under section 25(2) of the Constitution because there is no common law authority for expropriation. Therefore, the principal conclusion of the thesis is that the courts’ decision that accession had either occurred or not would generally be in line with the property clause of the Constitution. / AFRIKAANSE OPSOMMING: Inaedificatio behels dat roerende sake wat permanent deur bebouing aan grond vasgeheg is ophou bestaan as selfstandige sake en deel word van die grond. Die howe het in die verlede verskillende benaderings gevolg in hulle pogings om vas te stel of inaedificatio plaasgevind het. Daar word soms beweer dat die howe wegbeweeg het van die sogenaamde tradisionele benadering, wat op die objektiewe faktore gefokus het, na die sogenaamde nuwe benadering waarin die klem op die eienaar van die roerende goed se bedoeling val. Hierdie verhandeling analiseer die toepaslike regspraak en kom tot die gevolgtrekking dat daar onvoldoende bewys van so ‘n verskuiwing bestaan, aangesien sowel ouer sake wat met die tradisionele benadering geassosieer word en later regspraak wat die nuwe benadering sou volg klem op die eienaar van die roerende sake se bedoeling plaas. Die regspraak bied wel bewyse vir ‘n versigtige gevolgtrekking op ‘n ander punt, naamlik dat bepaalde ouer en later sake die eienaar van die roerende goed se bedoeling vir kommersiële beleidsredes beklemtoon, spesifiek in gevalle waar eiendomsreg in ‘n kredietkoop voorbehou is. Grondwetlike analise van hierdie gevolgtrekkings in die lig van die FNB-metodologie suggereer dat die howe se beslissing dat aanhegting wel plaasgevind het in gevalle waar permanente aanhegting van roerende goed aan grond ter sprake was oor die algemeen ‘n ontneming van eiendom vir doeleindes van artikel 25(1) van die Grondwet sal daarstel, maar aangesien daar oor die algemeen voldoende rede vir die ontneming is sal dit nie arbitrêr wees nie. Aan die ander kant, waar die howe beslis dat daar geen aanhegting was nie omdat eiendomsreg van die roerende goed vir sekerheid onderhewig aan ‘n kredietkoop voorbehou is, is daar geen ontneming van eiendom nie omdat die grondeienaar, die enigste party wat beswaar teen die beslissing mag maak, nie ‘n eiendomsbelang vir doeleindes van artikel 25(1) kan bewys nie. Verder stel die howe se beslissing dat aanhegting óf plaasgevind het al dan nie in elk geval geen onteiening daar nie aangesien daar geen magtiging vir onteiening in die gemenereg bestaan nie. Die gevolgtrekking van die verhandeling is dat die howe se beslissing dat aanhegting óf plaasgevind het al dan nie oor die algemeen nie in stryd met die eiendomsbepaling in die Grondwet sal wees nie.

This thesis examines the book in the nineteenth century by way of an unusual corpus: movable and novelty books for children, drawn from the Opie Collection of Children’s Literature at the Bodleian Library. It argues that these items, which have been either ignored or actively dismissed by scholars of children’s literature, are of two-fold significance for the history of the book: they encourage a sense of the book as a constitutively (rather than an incidentally) material object, and they demand an understanding of reading as not just a mental activity, but a physical one as well. Each of the first five chapters of the thesis centres on a different format. The opening chapter discusses the Regency-era paper doll books produced by Samuel and Joseph Fuller, exposing the tension between form and content in these works. The second chapter looks at Victorian panorama books for children, showing how the panorama format affects space, time, and the structure of any text accompanying the image. The third chapter reads the pop-up book’s key tension—the tension between surface and depth in the pursuit of an illusion of three dimensions—in terms of flat, theatrical, and stereoscopic picture-making, three other nineteenth-century pictorial modes in which an illusion of three-dimensionality is important. The fourth chapter traces self-reflexive accounts of printing, publishing, and the material book in dissolving-view books produced by the German publisher and printer Ernest Nister at the end of the nineteenth century. The fifth chapter positions the late nineteenth-century mechanical books designed and illustrated by Lothar Meggendorfer in terms of two material analogies, the puppet and the mechanical toy or automaton. The final chapter synthesizes evidence as to how the movable book could and should be read from across formats, foregrounding in particular the ways in which the movable embodies reading.

Tipos móveis de metal da Funtimod: contribuições para história tipográfica brasileira A fundição de tipos móveis de metal foi uma atividade primordial para o funcionamento das artes gráficas desde seu desenvolvimento, no século 15, até meados do século 20. Entretanto, as primeiras casas fundidoras foram instaladas no Brasil apenas no começo dos anos oitocentistas - quando a técnica ainda era realizada com procedimentos manuais -, poucos anos depois da corte portuguesa ter permitido a reprodução de impressos em território nacional. Inovações tecnológicas do século 19, principalmente máquinas fundidoras e equipamentos para gravar punções e matrizes, transformaram as oficinas de fundição em indústrias. Dentro deste contexto industrial, a Funtimod, objeto de estudo desta pesquisa de doutorado, operou durante quase todo o século 20. A empresa, que pode ser considerada a maior fundição de tipos brasileira, foi fundada na cidade de São Paulo, em 1932, por uma colaboração entre os alemães Karl H. Klingspor e Josef Tscherkassky, a empresa alemã-brasileira Sociedade Técnica Bremensis e a fundição suíça Haas, que estava representando a fundição alemã D. Stempel. Com filiais em Belo Horizonte, Curitiba, Porto Alegre, Recife e Rio de Janeiro, a Funtimod serviu a indústria gráfica nos quatro cantos do País, comercializando máquinas e todo tipo de material tipográfico. Embora os tipos móveis de metal fundidos pela empresa sejam o foco desta investigação, o estudo de caso Funtimod também abordou sua trajetória histórica e a fábrica de tipos, por intermédio de coleta de dados em cinco fontes de evidência diferentes: registros, documentos, entrevistas, observações não-participantes e artefatos físicos. Desse modo, foi possível salientar a dependência de empresas alemãs para o desenvolvimento dos negócios no que tange aos produtos comercializados. Se a Funtimod estava aparelhada, nos moldes das fundições europeias, para manufaturar um tipo desde o desenho até a fundição, definitivamente, o design das faces não foi uma etapa valorizada. Grande parte dos tipos encontrados em nove catálogos da Funtimod, com repertórios tipográficos diferentes, foi identificada como sendo de origem alemã, principalmente das firmas D. Stempel e Klingspor. E, apesar de algumas faces não terem sido identificadas em outras fundições brasileiras ou estrangeiras, não foram encontradas evidências de que a Funtimod tenha lançado no Brasil alguma face com desenho original. A coleção de tipos Funtimod, por outro lado, é formada por faces representativas do começo do século 20, como Futura, Kabel, Memphis e Mondial, assim como revivals da Bodoni e Garamond. Análises comparativas dos tipos móveis de metal da Funtimod revelaram práticas singulares realizadas na fábrica de tipos brasileira. No meio de designs internacionalmente conhecidos, por exemplo, alguns caracteres, em especial os conjugados com os diacríticos til e cedilha, apresentam variações de forma, posicionamento, peso e tamanho na mesma face. As considerações desta investigação contribuem para a história tipográfica brasileira de uma forma particular, numa relação intrínseca com a Alemanha, que, sobretudo, levaram-me a questionar o quão brasileira a Funtimod realmente foi. / Type founding was one of the most important activities for the graphic arts since its beginning in the fifteenth century until the middle of twentieth century. However, the first type foundries were only installed in Brazil in the beginning of 1800s a few years after the Portuguese Court allowed printing in Brazilian lands, and when the technique was still performed with manual methods. Technical innovations developed in the nineteenth century, mainly, typecasting machines and pantograph punchcutting machines, which transformed type foundries into industries. Within this industrial context, Funtimod, the subject of this doctoral research and the largest Brazilian type foundry, operated during almost the entire twentieth century. Funtimod was founded in 1932 in São Paulo by a collaboration of two Germans (Karl H. Klingspor and Josef Tscherkassky), the German-Brazilian company Sociedade Técnica Bremensis, and the Swiss type foundry Haas. With branches in Belo Horizonte, Curitiba, Porto Alegre, Recife e Rio de Janeiro, Funtimod supplied the graphic industry across the four corners of the country, selling all kinds of typographic materials as well as machines. Although the movable metal types cast by the company were the focus of this investigation, the case study of Funtimod also explored its historic development and the factory, through data gathered from multiple sources: specimens, documents, interviews, non-participant observations, and physical artefacts. Thereby, the evidence suggests Funtimod\'s reliance on German companies for its business development in respect to the products manufactured in Brazil. Seeing that Funtimod was equipped, like European foundries, to manufacture types from the design until the casting phases, definitely, the originality of the typeface\'s design was not considered valuable by the factory. The majority of faces, which were found in nine specimens with different typographic collections, were identified as being German, especially from D. Stempel and Klingspor foundries. Moreover, although some of the faces have not been identified in other foundries, evidence was not found that Funtimod had released in Brazil any face cast with an original design. Funtimod type collection, on the other hand, is composed with representative faces from the beginning of the twentieth century, such as Futura, Kabel, Memphis, Mondial, as well as revivals of Bodoni and Garamond. Comparative analysis of movable metal types from Funtimod revealed that singular practices were performed at the Brazilian type foundry. Among internationally well-known faces, for instance, some characters, especially the ones joined with the tilde and cedilla diacritics, presented variations in form, position, weight and size. The findings of this investigation contribute to the Brazilian typographic history in a particular way, in a intrinsic relationship with Germany, that, above all, led me to question how Brazilian Funtimod really was.

Credit is an asset of the creditor that can be transferred, allowing event the constitutionof a security on it. Now, despite the fact that the remuneration the worker perceives is also a credit, the Law of Movable Collaterals has expressly excluded security possibilities on it, limiting the property right of the worker and economically damaging him. Is this right?In this article, the author develops the answer to this question, through a systematic interpretation of Peruvian legislation and the credit figure as an object of movable collateral. / El crédito es un activo del acreedor que puede ser transferido, permitiéndose, incluso, que se constituya garantía sobre el mismo. Ahora bien, pese a que la remuneración quepercibe el trabajador también es un crédito, la Ley de Garantía Mobiliaria la ha excluido expresamente de las posibilidades de garantía, limitando el derecho de propiedad del trabajador y perjudicándolo económicamente. ¿Es esto correcto?En el presente artículo, el autor desarrolla la respuesta a dicha interrogante, mediante una interpretación sistemática de la normativa peruana y la figura del crédito como objeto de garantía mobiliaria.

Shifts in economics, demographics, and lifestyle in America have lead to changes in this country's urban landscape. Rural and urban populations have migrated toward the suburbs and concentrated metro areas, leaving holes in the urban fabric of small and midsized cities. Often these empty spaces become drivers of blight, crime, and discouragement in the community. The goal of the Grow Pods Project is to transform the negative of vacant urban lots into an opportunity for improving health, building community, and encouraging positive growth. As a tool for integrating the food system directly into the urban context, this project addresses the need for innovative solutions to the complex issues of city land use. Grow Pods aim to help communities redirect a trajectory of decline toward a future that is focused on the health and wellbeing of the urban environment and the people who live in it. Transformation and transportability are intrinsic features of the design, in acknowledgement of the necessity for any component of a contemporary city in flux to be dynamic enough to reinvent itself within its evolving context. The Grow Pod project is focused on the South End Neighborhood of Springfield, MA, a city whose population and industrial base has decreased since much of its infrastructure was designed. Located in the fertile Connecticut River Valley, it is also in a region with a rich agricultural history.

Interconnects in power module result in thermal interfaces. The thermal interfaces degrade under thermal cycling, or chemical loading. Moreover, the reliability of thermal interfaces can be especially problematic when the interconnecting area is large, which increases its predisposition to generate defects (voids, delamination, or nonuniform quality) during processing. In order to improve the quality of the bonding process, as well as to be able to accurately assess interface reliability, it would be desirable to have a simple, reliable, and nondestructive measurement technique that would produce a 2-d map of the interface thermal resistance across a large bonded area. Based on the transient thermal method of JEDEC standard 51-14, we developed a measurement technique that involves moving a thermal sensor discretely across a large-area bonded substrate and acquiring the interface thermal resistance at each location. As detailed herein, the sensor was fabricated by packaging an IGBT bare die. An analytical thermal model was built to investigate the effects of thermal sensor packaging materials and structural parameters on the sensitivity of the measurement technique. Based on this model, we increased the detection sensitivity of the sensor by modifying the size of the sensor substrate, the material of the sensor substrate, the size of the IGBT bare die, the size of the heat sink, and the thermal resistance between sample and the heat sink. The prototype of the thermal sensor was fabricated by mounting Si IGBT on copper substrate, after which the Al wires were ultrasonic bonded to connect the terminals to the electrodes. The sensor was also well protected with a 3-d printed fixture. Then the edge effect was investigated, indicating the application of the thermal sensor is suitable for samples thinner than the value in TABLE 2 3. The working principle of the movable thermal sensor – Zth measurement and its structure function analysis – was then evaluated by sequence. The Zth measurement was evaluated by measuring the Zth change of devices induced by degradation in sintered silver die-attach layer during temperature cycling. At the end of the temperature cycling, failure modes of the sintered silver layer were investigated by scanning electron microscope (SEM) and X-ray scanning, to construct a thermal model for FEA simulation. The simulation results showed good agreement with the measured Zth result, which verified the accuracy of the test setup. The sensitivity of structure function analysis was then evaluated by measuring thermal resistance (Rth) of interface layers with different thermal properties. The structure function analysis approach successfully detected the Rth change in the thermal interface layer. The movable thermal sensor was then applied for 2d-mapping of the interface Rth of a large-area bonded substrate. Examining the test coupons bonded by sintered silver showed good and uniform bonding quality. The standard deviation of Rth is about 0.005 K/W, indicating the 95% confidence interval is about 0.01 K/W, which is commonly chosen as the error of measurement. The sensitivity of the movable thermal sensor was evaluated by detecting defects/heat channels of differing sizes. The 2-d mapping confirmed that the thermal sensor was able to detect defect/heat channel sizes larger than 1x1 mm2. The accuracy of the sensitivity was verified by FEA simulation. Moreover, the simulated results were consistent with the measured results, which indicates that the movable sensor is accurate for assessing interface thermal resistance. In summary, based on structure function analysis of the transient thermal impedance, the concept of a movable thermal sensor was proposed for two-dimensional mapping of interface thermal resistance. (1) Preliminary evaluation of this method indicated both transient thermal impedance and structure function analysis were sensitive enough to detect the thermal resistance change of thermal interface layers. With the help of transient thermal impedance measurement, we non-destructively tested the reliability of sintered silver die-attach layer bonded on either Si3N4 AMB or AlN DBA substrates. (2) An analytical thermal model was constructed to evaluate the design parameters on the sensitivity and resolution of the movable thermal sensor. A detailed design flow chart was provided in this thesis. To avoid edge effect, requirements on thickness and materials of test coupon also existed. Test coupon with smaller thermal conductivity and larger thickness had a more severe edge effect. (3) The application of the movable sensor was demonstrated by measuring the 2-d thermal resistance map of interface layers. The results indicated for bonded copper plates (k = 400 W/mK) with thickness of 2 mm, the sensor was able to detect defect/heat channel with size larger than 1x1 mm2. / Doctor of Philosophy / Interconnects in power module result in thermal interfaces.

A thermal model was also constructed to guide the design of the sensor, to increase its performance. Moreover, the preliminary test of the test setup was conducted to prove its feasibility for the sensor. Eventually, the sensor’s performance and application was demonstrated by measuring the 2-d thermal resistance map of the bonded interfaces.

Este estudo de abordagem qualitativa, descritivo e de caráter exploratório tem como objetivo investigar a vivência da equipe multiprofissional na assistência ao adulto em situação de parada cardiorrespiratória, numa unidade de suporte avançado de vida de Atendimento Pré-Hospitalar móvel (APH) da Secretaria Municipal de Saúde de Ribeirão Preto-SP. Para a coleta de dados, foi utilizada a entrevista semi-estruturada que compreendeu questões sobre o perfil sociodemográfico, profissional e questões norteadoras sobre o tema. A amostra foi constituída por 16 profissionais, médicos, enfermeiros e condutores de veículo de urgência terrestre integrantes da Unidade de Suporte Avançado (USA). Os dados foram organizados por meio da análise de conteúdo proposta por Bardin (1977), sendo identificados quatro temas: o trabalho no APH móvel avançado, os sentimentos e emoções da equipe multiprofissional de APH móvel avançado frente ao atendimento à Parada Cardiorrespiratória (PCR), identificação dos agentes estressores ao atendimento à PCR e as reações de estresse no atendimento à PCR. Na presente pesquisa, a equipe multiprofissional relata a sua vivência nesse tipo de atividade com a visão de um serviço desafiante e difícil, por vivenciar diariamente situações inesperadas, desconhecidas e angustiantes, mas que, com tudo isso, também são capazes de perceber satisfações pessoais e realização profissional. Na análise, evidenciaram-se também nas demais categorias, as expressões: conhecimento e constante capacitação técnica e tecnológica, habilidade e agilidade, tomada de decisões, trabalho em equipe, a dificuldade de lidar com o sofrimento dos familiares na cena do agravo, envolvimento emocional em situações de grande sofrimento e dor, trabalhar em altas temperaturas, dificuldades em lidar com a morte, principalmente em situações inesperadas e com vítimas jovens, trazendo sentimentos de impotência, frustração e tristeza. Portanto essa equipe multiprofissional vivencia diariamente a real possibilidade de sofrimento psíquico e mostra por meio deste estudo, a necessidade de que a equipe promova momentos para reflexão e discussão acerca dos aspectos técnicos, científicos e éticos referentes ao cuidado dos pacientes críticos, em parada cardiorrespiratória, quanto às diferentes possibilidades de situações que os envolva durante o atendimento, com vistas à melhoria da qualidade do atendimento e do relacionamento interpessoal. Levando em consideração os resultados e conclusões da nossa investigação, é relevante a questão da saúde mental desses profissionais no exercício de suas funções, diante do exposto nos seus próprios relatos, e até que ponto os mecanismos de enfrentamento utilizados pelos mesmos são eficientes, ou seja, são métodos eficazes de elaboração do estresse. Sugerimos como métodos que podem ser eficazes: buscar informações e discutir o assunto em grupos; aceitar os acontecimentos, buscando o lado positivo da situação, buscar auxílio de especialistas, psicólogos ou psiquiatras e seguir suas orientações. Diante da importância desse serviço, vemos a necessidade de propor formas alternativas dentro dessa equipe, para que ela alcance um equilíbrio no estresse individual e coletivo e que efetivamente não atinja os limites de sofrimento psíquico. Assim são necessárias outras investigações, porque as seqüelas advindas podem comprometer a vida social e pessoal do indivíduo. / This study of qualitative boarding and of exploratory character has as objective investigate the experience of the multi-professional team in the assistance for the adults in situations of cardiorespiratory emergency in a unity of advanced support of life and movable pre-hospitalar attendance (APH) of the Municipal Secretary of Health from Ribeirão Preto?SP.

Which are some of the main trends, in terms of graphic design, illustration, and text, in books that are preferably addressed to toddlers (zero to three years old) in Brazilian contemporaneity? (2.) How can the language's symbolic values contribute to the education of a child at such early age? To follow our course, we've selected, as a corpora of research, ten titles that compose the collection of 2014 PNBE, addressed to children between zero and three years old. As a hypothesis, we suggest that these books, addressed preferably to children who do not read yet, bring specific and particular elements that characterize trends on books for toddlers in terms of graphic design, illustration, and text, and that they are, therefore, amenable for literary analysis; and that, in contact with Literature, babies can learn the aesthetic language, which corroborates their individual and relational potential, providing a profitable environment for developing global skills. To pursue the present study – qualitative, exploratory, and descriptive – it was developed in three chapters. In chapter I, the reasons for approaching the subject are discussed, presenting the development of the young child and the encounter between Literature and toddlers, resorting on reflections by Bernard Golse, Antonio Candido, and Betina Kümmerling-Meibauer. In Chapter II, we present the corpora of this study and justify its choice. In addition, we address the PNBE program and its collection for early childhood, as well as the assessment criteria established in the present study for the analysis of the corpus, based, therefore, on the 2014 PNBE edict and the handbook that accompanies this specific collection. In chapter III, the books are analyzed in terms of graphic design, illustration, and text, using considerations by Rosinha, Sophie Van der Linden, and Ana Margarida Ramos on graphic design aspects; by Adriana Baptista and Annete Werner's regarding illustration; and by Antonio Candido, Octavio Paz, and Kathleen Ahrens's in terms of the literary text / No intento de contribuir com as discussões recentes acerca da relação literatura-bebê, o presente estudo tem como objetivo responder às seguintes questões direcionadoras: Quais são algumas das principais tendências, em termos de projeto gráfico, ilustração e texto, nos livros preferencialmente endereçados aos bebês (zero a três anos) na contemporaneidade brasileira? Como os valores simbólicos da linguagem podem contribuir para a educação da criança em sua tenra idade? Para efetuarmos esse percurso, selecionamos como corpus de pesquisa dez títulos que compõem o acervo do PNBE 2014, endereçados a crianças entre zero e três anos. Sugerimos, como hipótese, que estes livros, endereçados preferencialmente às crianças que ainda não leem, trazem elementos específicos e particulares que caracterizam tendências dos livros para bebês no projeto gráfico, na ilustração e no texto, sendo, portanto, passíveis à análise literária; e que, ao contato com a Literatura, os bebês apreendem a linguagem estética, o que corrobora com o seu potencial individual e relacional, proporcionando um ambiente profícuo às habilidades globais em desenvolvimento. Para tal, o presente estudo – qualitativo, exploratório e descritivo – foi desenvolvido em três capítulos. No capítulo I, entram em discussão as razões para a abordagem do tema na atualidade, apresentando o desenvolvimento da criança pequena e o encontro entre a Literatura e o bebê, recorrendo-se, para isso, às reflexões de Bernard Golse, Antonio Candido e Betina Kümmerling-Meibauer. No capítulo II, apresenta-se o corpora deste estudo e a justificativa de sua escolha. Em adição, aborda-se o programa PNBE e seu acervo para primeiríssima infância, bem como os critérios de avaliação estabelecidos no presente estudo para a análise do corpora, pautando-se, para tanto, no edital PNBE 2014 e no Manual que acompanha esse acervo em específico. No capítulo III, analisa-se os livros em termos de projeto gráfico, de ilustração e de texto, valendo-se das considerações de Rosinha, Sophie Van der Linden e Ana Margarida Ramos no que se refere ao projeto gráfico; de Adriana Baptista e Annete Werner no tocante à ilustração; e de Antonio Candido, Octavio Paz e Kathleen Ahrens nas reflexões acerca do texto literário
