Utilização do mapa espacial de radiação e dose acumulada como ferramenta para otimização de doses em pacientes e trabalhadores nas clínicas de medicina nuclear

This study has as general aim to propose a spatial map of doses as an auxiliary tool in assessing the need for optimization of the workplace in nuclear medicine services. As specific aims, we assessed the workers individual dosimetry; we analyzed the facilities of the nuclear medicine services; and we evaluated environment exposure rates. The research is characterized as a case study, with an exploratory and explanatory nature. It was conducted in three Nuclear Medicine Services, all established in the Northwest of the Paraná State. Results indicated that the evaluated dose rates and workers dosimetry, in all the dependencies of the surveyed services, are within the limits of annual doses. However some exceeded the limits recommended in the standard CNEN-NN 3:01 (2014). It was concluded that the spatial map dose is an important tool for nuclear medicine services because it facilitates the visualization of areas with highest concentration of radiation, and also helps in the constant review of these measures and resources, aiding in the identification of any failures and shortcomings, providing resources to correct any issues and prevent their repetition. The spatial map dose is also important for the regular inspection, evaluating if the radiation protection objectives are being met.

Emprego para jovens cientistas no sector empresarial : Expectativas e realidade

A formação avançada de recursos humanos tem vindo a ser objecto de um elevado investimento, com base no pressuposto de que estes recursos desempenham um papel crucial no desenvolvimento tecnológico. No entanto, os jovens pós-graduados têm vindo a deparar-se com dificuldades crescentes no mercado de trabalho académico, dificuldades essas que não estão a ser compensadas com o aparecimento de novas oportunidades no mercado de trabalho empresarial. Tal sugere a existência de alguma desadequação entre a oferta e a procura, ou seja, entre as competências dos indivíduos e as pretendidas por um mercado de trabalho em mutação. Este artigo aborda esse problema, examinando a questão do emprego de jovens cientistas no sector empresarial em Portugal. A investigação foi conduzida tendo em consideração quer o ponto de vista das empresas, quer o dos jovens cientistas e centrou-se nas seguintes questões: a) no caso das empresas que empregam mestres e doutorados, que tipo de competências são procuradas, como são geridos este tipo de recursos e que tipo de obstáculos se deparam à sua integração e utilização plena; b) no caso das empresas que não empregam, mas que poderiam beneficiar destes recursos, quais os motivos para a sua relutância; c) no caso dos jovens cientistas, qual a sua atitude em relação a uma carreira no sector empresarial e em que condições estariam dispostos a segui-la. A investigação permitiu detectar alguns desajustamentos entre os objectivos e expectativas das empresas e dos cientistas, bem como identificar alguns factores de relutância em ambos os grupos. Estes resultados permitiram- nos avançar algumas sugestões no sentido de promover o emprego de jovens cientistas no sector empresarial.

Przestrzenne formy upamiętniania Zagłady

This book is a synthesizing reflection on the Holocaust commemoration, in which space becomes a starting point for discussion. The author understands space primarily as an amalgam of physical and social components, where various commemorative processes may occur. The first part of the book draws attention to the material aspect of space, which determines its character and function. Material culture has been a long ignored and depreciated dimension of human culture in the humanities and social sciences, because it was perceived as passive and fully controlled by human will, and therefore insignificant in the course of social and historical processes. An example of the Nazi system perfectly illustrates how important were the restrictions and prohibitions on the usage of mundane objects, and in general, the whole material culture in relation to macro and micro space management — the state, cities, neighborhoods and houses, but also parks and swimming pools, factories and offices or shops and theaters. The importance of things and space was also clearly visible in exploitative policies present in overcrowded ghettos and concentration and death camps. For this very reason, when we study spatial forms of Holocaust commemoration, it should be acknowledged that the first traces, proofs and mementoes of the murdered were their things. The first "monuments" showing the enormity of the destruction are thus primarily gigantic piles of objects — shoes, glasses, toys, clothes, suitcases, toothbrushes, etc., which together with the extensive camps’ space try to recall the scale of a crime impossible to understand or imagine. The first chapter shows the importance of introducing the material dimension in thinking about space and commemoration, and it ends with a question about one of the key concepts for the book, a monument, which can be understood as both object (singular or plural) and architecture (sculptures, buildings, highways). However, the term monument tends to be used rather in a later and traditional sense, as an architectural, figurative form commemorating the heroic deeds, carved in stone or cast in bronze. Therefore, the next chapter reconstructs this narrower line of thinking, together with a discussion about what form a monument commemorating a subject as delicate and sensitive as the Holocaust should take on. This leads to an idea of the counter-monument, the concept which was supposed to be the answer to the mentioned representational dilemma on the one hand, and which would disassociate it from the Nazi’s traditional monuments on the other hand. This chapter clarifies the counter-monument definition and explains the misunderstandings and confusions generated on the basis of this concept by following the dynamics of the new commemorative form and by investigating monuments from the ‘80s and ‘90s erected in Germany. In the next chapter, I examine various forms of the Holocaust commemoration in Berlin, a city famous for its bold, monumental, and even controversial projects. We find among them the entire spectrum of memorials – big, monumental, and abstract forms, like Peter Eisenman’s Memorial to the Murdered Jews of Europe or Daniel Liebeskind’s Jewish Museum Berlin; flat, invisible, and employing the idea of emptiness, like Christian Boltanski’s Missing House or Micha Ullman’s Book Burning Memorial; the dispersed and decentralized, like Renata Stih and Frieder Schnock’s Memory Places or Gunter Demnig’s Stumbling Blocks. I enrich descriptions of the monuments by signaling at this point their second, extended life, which manifests itself in the alternative modes of (mis)use, consisting of various social activities or artistic performances. The formal wealth of the outlined projects creates a wide panorama of possible solutions to the Holocaust commemoration problems. However, the discussions accompanying the building of monuments and their "future life" after realization emphasize the importance of the social component that permeates the biography of the monument, and therefore significantly influences its foreseen design. The book also addresses the relationship of space, place and memory in a specific situation, when commemoration is performed secretly or remains as unrealized potential. Although place is the most common space associated with memory, today the nature of this relationship changes, and is what indicates popularity and employment of such terms as Marc Augé’s non-places or Pierre Nora’s site of memory. I include and develop these concepts about space and memory in my reflections to describe qualitatively different phenomena occurring in Central and Eastern European countries. These are unsettling places in rural areas like glades or parking lots, markets and playgrounds in urban settings. I link them to the post-war time and modernization processes and call them sites of non-memory and non-sites of memory. Another part of the book deals with a completely different form of commemoration called Mystery of memory. Grodzka Gate - NN Theatre in Lublin initiated it in 2000 and as a form it situates itself closer to the art of theater than architecture. Real spaces and places of everyday interactions become a stage for these performances, such as the “Jewish town” in Lublin or the Majdanek concentration camp. The minimalist scenography modifies space and reveals its previously unseen dimensions, while the actors — residents and people especially related to places like survivors and Righteous Among the Nations — are involved in the course of the show thanks to various rituals and symbolic gestures. The performance should be distinguished from social actions, because it incorporates tools known from religious rituals and art, which together saturate the mystery of memory with an aura of uniqueness. The last discussed commemoration mode takes the form of exposition space. I examine an exhibition concerning the fate of the incarcerated children presented in one of the barracks of the Majdanek State Museum in Lublin. The Primer – Children in Majdanek Camp is unique for several reasons. First, because even though it is exhibited in the camp barrack, it uses a completely different filter to tell the story of the camp in comparison to the exhibitions in the rest of the barracks. For this reason, one experiences immersing oneself in all subsequent levels of space and narrative accompanying them – at first, in a general narrative about the camp, and later in a specifically arranged space marked by children’s experiences, their language and thinking, and hence formed in a way more accessible for younger visitors. Second, the exhibition resigns from didacticism and distancing descriptions, and takes an advantage of eyewitnesses and survivors’ testimonies instead. Third, the exhibition space evokes an aura of strangeness similar to a fairy tale or a dream. It is accomplished thanks to the arrangement of various, usually highly symbolic material objects, and by favoring the fragrance and phonic sensations, movement, while belittling visual stimulations. The exhibition creates an impression of a place open to thinking and experiencing, and functions as an asylum, a radically different form to its camp surrounding characterized by a more overwhelming and austere space.

LABOUR MARKET AND TRAINING LIBRARIANS

Forty years ago began in Medellin, Colombia the officers of study on the training of librarians and the improvement of library service in Latin America. It was the first time was a regional effort of this nature.Reviewing the documents we see that concern for the subsequent employment of graduates are handled in a "serene". The library moved into a more stable labor market and institutionally defined. The challenges facing those who were far from threatening the stability of employment, the very meaning of the profession and survival. The race was expanding, had begun to trickle out of the national libraries of some countries to join full of expectations to the academic university.

Planejamento municipal do turismo: diretrizes e perspectivas - o caso da SETURDE

Given the uncertainties of the environment in today's world, strategic planning is again discussed as an important tool to position the organization in future likely. To address this a more dynamic and less linear, trying to adapt the multiple realities, the method of scenarios can be one of the strategies to anticipate future designs. In the public sphere, an efficient implementation of human resources and financial managers require a new approach to the formulation of strategies. Tourism, in turn, presents itself as an important segment of the national economy shaped up as a major source of funds for the formation of the Gross Domestic Product - GDP - of states and municipalities. This study aims to know the guidelines and perspectives of municipal planning of tourism in the city of Natal/RN from the case by the representatives of the sector. The survey was developed based on a qualitative, exploratory, based on the case in the Secretaria Municipal de Turismo e Desenvolvimento Econômico - SETURDE. The results express that the body goes through a time of changes in its organizational structure and in defining its role with the local tourism. The national plan for tourism and the choice of Christmas as the host city for the World Cup in 2014 have stimulated interest in developing a formal strategic planning in the organization. However, when it comes to more complex tools, such as the method of future scenarios, the technical know its definition and importance for future actions. The results presented support the conclusion that the actions are designed intuitively and without complying with the scientific methods developed for this purpose, as the method of strategic scenarios. However, the evidence beginning to emerge from the plans and documents issued by the federal government, as well as the Secretary's own initiative, direct the actions of the body to coordinate and act as a fulcrum for local action to the increase in tourism

MICROFLUIDIC ASSAY PERFORMANCE ENHANCEMENT USING POROUS VOLUMETRIC DETECTION ELEMENTS FOR IMPEDEMETRIC AND OPTICAL SENSING

Microfluidic technologies have great potential to help create automated, cost-effective, portable devices for rapid point of care (POC) diagnostics in diverse patient settings. Unfortunately commercialization is currently constrained by the materials, reagents, and instrumentation required and detection element performance. While most microfluidic studies utilize planar detection elements, this dissertation demonstrates the utility of porous volumetric detection elements to improve detection sensitivity and reduce assay times. Impedemetric immunoassays were performed utilizing silver enhanced gold nanoparticle immunoconjugates (AuIgGs) and porous polymer monolith or silica bead bed detection elements within a thermoplastic microchannel. For a direct assay with 10 µm spaced electrodes the detection limit was 0.13 fM AuIgG with a 3 log dynamic range. The same assay was performed with electrode spacing of 15, 40, and 100 µm with no significant difference between configurations. For a sandwich assay the detection limit was10 ng/mL with a 4 log dynamic range. While most impedemetric assays rely on expensive high resolution electrodes to enhance planar senor performance, this study demonstrates the employment of porous volumetric detection elements to achieve similar performance using lower resolution electrodes and shorter incubation times. Optical immunoassays were performed using porous volumetric capture elements perfused with refractive index matching solutions to limit light scattering and enhance signal. First, fluorescence signal enhancement was demonstrated with a porous polymer monolith within a silica capillary. Next, transmission enhancement of a direct assay was demonstrated by infusing aqueous sucrose solutions through silica bead beds with captured silver enhanced AuIgGs yielding a detection limit of 0.1 ng/mL and a 5 log dynamic range. Finally, ex situ functionalized porous silica monolith segments were integrated into thermoplastic channels for a reflectance based sandwich assay yielding a detection limit of 1 ng/mL and a 5 log dynamic range. The simple techniques for optical signal enhancement and ex situ element integration enable development of sensitive, multiplexed microfluidic sensors. Collectively the demonstrated experiments validate the use of porous volumetric detection elements to enhance impedemetric and optical microfluidic assays. The techniques rely on commercial reagents, materials compatible with manufacturing, and measurement instrumentation adaptable to POC diagnostics.

¿EXISTE DISCIPLINA DE MERCADO EN EL SISTEMA BANCARIO COSTARRICENSE?

El objetivo principal del presente estudio consistió en evaluar la existencia o no de disciplina de mercado en el sistema bancario costarricense lo cual puede ser una evidencia importante previo al posible establecimiento de un Fondo de Garantía de los depósitos bancarios en Costa Rica.De acuerdo con los resultados de las estimaciones, podría afirmarse que la hipótesis de la existencia de disciplina de mercado en el sistema bancario costarricense se comprobó aunque de una manera muy débil o incipiente.La mayor parte de las variables fundamentales del desempeño y que reflejan el nivel de riesgo asumido por los intermediarios bancarios no parecen tener influencia sobre el comportamiento de los depósitos al igual que con la mayoría de las variables macroeconómicas.Los resultados también indican que la captación en cada uno de los bancos comerciales, si bien reacciona de igual manera ante los cambios en las variables explicativas, cada una de las instituciones presenta ciertas particularidades que los hacen diferentes entre sí. AbstractThe primary target of the present study consisted of evaluating the existence or not of market discipline in the Costa Rican banking system which can be previous an important evidence to the possible establishment of a guarantee system of the banking deposits in Costa Rica.In agreement with the results of the estimations, it could affirm that the hypothesis of the existence of market discipline in the Costa Rican banking system was verified although of a very weak or incipiente way.Most of the fundamental variables of the performance and that they reflect the level of risk assumed by the banking intermediaries does not seem to have influence on the behavior of the deposits like with most of the macroeconomic variables.The results also indicate that the pick up of funds in each one of the commercial banks, although reacts of equal way before the changes in the explanatory variables, each one of the institutions displays certain characteristics that are reflected in different intercepts.

Essays on Financial Constraints, R&D Investments, and Competition

This dissertation consists of two chapters of theoretical studies that investigate the effect of financial constraints and market competition on research and development (R&D) investments. In the first chapter, I explore the impact of financial constraints on two different types of R&D investments. In the second chapter, I examine the impact of market competition on the relationship between financial constraints and R&D investments. In the first chapter, I develop a dynamic monopoly model to study a firm’s R&D strategy. Contrary to intuition, I show that a financially constrained firm may invest more aggressively in R&D projects than an unconstrained firm. Financial constraints introduce a risk that a firm may run out of money before its project bears fruit, which leads to involuntary termination on an otherwise positive-NPV project. For a company that relies on cash flow from assets in place to keep its R&D project alive, early success can be relatively important. I find that when the discovery process can be expedited by heavier investment (“accelerable” projects), a financially constrained company may find it optimal to “over”-invest in order to raise the probability of project survival. The over-investment will not happen if the project is only “scalable” (investment scales up payoffs). The model generates several testable implications regarding over-investment and project values. In the second chapter, I study the effects of competition on R&D investments in a duopoly framework. Using a homogeneous duopoly model where two unconstrained firms compete head to head in an R&D race, I find that competition has no effect on R&D investment if the project is not accelerable, and the competing firms are not constrained. In a heterogeneous duopoly model where a financially constrained firm competes against an unconstrained firm, I discover interesting strategic interactions that lead to preemption by the constrained firm in equilibrium. The unconstrained competitor responds to its constrained rival’s investment in an inverted-U shape fashion. When the constrained competitor has high cash flow risk, it accelerates the innovation in equilibrium, while the unconstrained firm invests less aggressively and waits for its rival to quit the race due to shortage of funds.

O atual ambiente operacional, tem sentido profundas mudanças, fruto especialmente, da evolução tecnológica global, fazendo com que a tomada de decisão dependa ainda mais dos sistemas de informação. Para fazer face a esta realidade têm sido atualizadas e desenvolvidas conceções doutrinárias, onde se incluem as Operações de Informação, com o intuito de dar resposta aos desafios vindouros. Sendo o objeto de estudo deste trabalho as Operações de Informação, analisamos essa temática à luz da doutrina da Organização do Tratado do Atlântico Norte (OTAN) e do Exército Brasileiro, com vista a determinar contributos que possibilitem a sua conceção de emprego no Brasil a nível conjunto. Após tratada, sistematizada e analisada a informação recolhida, constatamos que a OTAN utiliza instrumentos de poder de maneira abrangente e tem conduzido as Operações de Informação para maximizar os efeitos produzidos no ambiente da informação, como uma função integradora de capacidades. O Exército Brasileiro possui doutrina consubstanciada de emprego tático das Operações de Informação. Assim sendo, esta investigação permitiu concluir que o estudo das Operações de Informação, através de contributos do Exército Brasileiro e da OTAN abre caminhos para o estabelecimento inicial de uma conceção doutrinária para o Brasil a nível conjunto. Abstract: The current operating environment, it makes sense profound changes, especially fruit, the global technological evolution, making decision making depends further information systems. To address this reality has been updated and developed doctrinal conceptions, which includes the Information Operations, in order to meet the challenges ahead. As the object of study of this work the Information Operations, we analyzed this issue in the light of the doctrine of the North Atlantic Treaty Organization (NATO) and the Brazilian Army, to determine contributions to enable your use of design in Brazil at the joint level. After treated, systemized and analyzed the information collected, we found that NATO uses power tools in a comprehensive manner and has led the Information Operations to maximize the effects in the information environment as an integrating function capabilities. The Brazilian Army has embodied the doctrine of tactical employment of Information Operations. Therefore, this investigation has concluded that the study of Information Operations through contributions of the Brazilian Army and NATO open paths for the initial establishment of a doctrinal design for Brazil at the joint level.

Fachada flexível para casa padronizada em condomínios

The employment of flexibility in the design of façades makes them adaptable to adverse weather conditions, resulting in both minimization of environmental discomfort and improvement of energy efficiency. The present study highlights the potential of flexible façades as a resource to reduce rigidity and form repetition, which are usually employed in condominiums of standardized houses; as such, the work presented herein contributes to field of study of architectural projects strategies for adapting and integrating buildings within the local climate context. Two façade options were designed using as reference the bionics and the kinetics, as well as their applications to architectural constructions. This resulted in two lightweight and dynamic structures, which cater to constraints of comfort through combinations of movements, which control the impact of solar radiation and of cooling in the environment. The efficacy and technical functionality of the façades were tested with comfort analysis and graphic computation software, as well as with physical models. Thus, the current research contributes to the improvement of architectural solutions aimed at using passive energy strategies in order to offer both better quality for the users and for the sustainability of the planet

Cofinanciamento das políticas sociais no contexto do federalismo brasileiro do século XXI

O arranjo federativo pós-Constituição de 1988 vem indicando a maior responsabilidade das unidades federativas e dos munícipios na execução das políticas sociais, ao mesmo tempo que se conferiu maior autonomia na arrecadação tributária. A partir dos anos 2000, as novas regulamentações das políticas sociais nas áreas de educação, saúde e assistência social vêm exigindo um maior esforço de recursos orçamentários dos estados, do Distrito Federal e dos municípios, sem a criação ou aporte de receitas fiscais adicionais. Nas políticas sociais, importantes mudanças legislativas marcam a primeira década do século XXI no Brasil, com implicações diretas no arranjo federativo e por consequência no cofinanciamento das políticas sociais. O objetivo principal do artigo é analisar o montante de recursos aplicados pela União, estados, DF e municípios nas funções orçamentárias: assistência social, saúde e educação, no período de 2002 a 2012, evidenciando o confinaciamento dessas políticas sociais; assim como o de identificar alguns obstáculos criados pelo ajuste fiscal em curso no país para a expansão do cofinanciamento das políticas sociais. __________________________________________________________________________________________________ ABSTRACT

Tridimensionalidade do Campo de Batalha

O presente Relatório Científico Final do Trabalho de Investigação Aplicada versa o emprego do Exército Português nas Operações de Combate em Ambiente Urbano, no âmbito das missões internacionais da North Atlantic Treaty Organization. Com a realização do presente trabalho pretende-se verificar e analisar a doutrina, organização, treino e meios do Exército Português para a condução de Operações de Combate em Ambiente Urbano em contexto das missões internacionais no âmbito da North Atlantic Treaty Organization. As características e tendências do atual ambiente operacional apontam para uma tipologia de Operações militares marcadas essencialmente por aspetos inerentes à complexidade do ambiente urbano. Apesar das suas particularidades, estas operações inserem-se em todo o espetro do conflito, inclusive em Operações de Apoio à Paz onde a ameaça pode provocar o escalar de violência. Desta forma o Exército Português terá que possuir capacidades militares que se adequem às possibilidades de atuação das forças em Teatros de Operações onde o ambiente é essencialmente urbano, possibilitando assim cumprir com a sua missão, assegurando os compromissos internacionais do Estado Português no âmbito militar. Assim, esta investigação iniciar-se-á com um enquadramento teórico, fundamentado numa pesquisa bibliográfica, seguida de uma componente prática, correspondente à análise documental e entrevistas que permitam obter respostas para a questão central em apreço. Estas duas componentes culminam com a conclusão do trabalho resultante do processo de investigação verificando que, apesar de algumas lacunas e limitações, as forças militares dispõem de inquestionáveis competências para conduzirem operações que envolvam combate em ambiente urbano no quadro das missões internacionais da North Atlantic Treaty Organization.
