As organizações - reproduzindo e aperfeiçoando a fónnula de substituição do trabalho do século XIX - estão investindo em novos modelos de gestão e tecnologias modernas, com o objetivo de reduzir seus custos, aperfeiçoar os seus produtos e agilizar os seus serviços. Sentindo a necessidade de se inserir nesse contexto~ o Estado, assim entendido como um todo, e, especialmente, o Poder Judiciário do Estado do Espírito Santo, tem buscado adaptar-se a tais mudanças, visto que o seu modelo administrativo e jurisdicional há muito tempo encontra-se ultrapassado, necessitando de novas abordagens. Entretanto, muitas têm sido as resistências à modernização administrativa e tecnológica, tanto por parte de uma corrente de juristas tradicionalistas, que, constantemente promovem um movimento de retomo a padrões e conceitos antigos, quanto pela escassez de recursos financeiros . A inovação envolve sempre o elemento de incerteza e, embora a história da humanidade detenha, durante a sua trajetória, registros de inovações em modelos de gestão e significativos avanços tecnológicos, atualmente eles vêm exigindo um maior percentual de conhecimentos diversificados, quebrando paradigmas que influenciam no comportamentodas organizações/instituições, num processo irreversível de crescimento dinâmico. A relevância desta pesquisa residiu em analisar o modelo de gestão e a inovação tecnológica do Poder Judiciário do Estado do Espírito Santo, a partir das transformações mundiais, além da sua importância nos mecanismos jurisdicionais, seja instantaneamente ou após um período de aprendizado combinado com a aceitação da inovação. Pretendeu-se, ainda, conhecer os efeitos dessas mudanças na cultura da instituição, tais como possíveis causas de resistência.

Buscando contribuir teórica e praticamente com a questão da qualidade de vida e melhoria na qualidade de desempenho do perito criminal, esta dissertação procurou apresentar como se desenvolve a atividade pericial e como enfrenta seus inerentes percalços. Durante o estudo foi possível mostrar alguns aspectos significativos da relação da administração de pessoas no setor privado e público. Fez-se aparecer, ainda, o comprometimento do profissional perito criminal na Administração Pública e os sentimentos gerados pelas peculiaridades apresentadas nas atividades por eles desempenhadas. O desvelamento dos sentimentos, durante as entrevistas com abordagem fenomenológica, fez emergir a relevância do humano apaixonado pela carreira e, ao mesmo tempo, preocupado com as condições de trabalho, mas sempre focado nos resultados em favor da sociedade pelo trabalho desenvolvido. A relação interpessoal e intrapessoal favoreceu o autoconhecimento e o conhecimento do outro visando à um estudo acerca do desenvolvimento humano e profissional. A importância da formação humana do profissional atuante em perícia criminalística fez-se presente quando da abordagem acerca da administração de pessoas em um momento em que os avanços tecnológicos e a globalização emergem fortemente na realidade concreta.

O trabalho tem por objetivo verificar de que forma os avanços científicos e tecnológicos da humanidade influenciaram a obra de Edgar Allan Poe e de Machado de Assis. A análise propõe revelar o olhar desses escritores acerca das novas possibilidades que eram oferecidas à sociedade com o intuito maior de evidenciar o papel da literatura nesse processo, uma vez que o homem é capaz de enxergar todo o comportamento de uma época e, conseqüentemente, a si mesmo, através da obra literária. Essa atitude de “olhar para trás” e para “dentro de si mesmo”, acredita-se, permite que o homem avance ainda mais. Para realizar a análise proposta, a pesquisa utiliza-se de conceitos como o de intertextualidade e interdisciplinaridade, muito caros à Literatura Comparada, com o fim de promover relações entre as diferentes áreas do saber – Literatura e Ciência –, entre os diferentes escritores e, por fim, entre os diversos gêneros literários que constituem o corpus do presente estudo. Após um breve panorama da história do desenvolvimento dos avanços científicos e tecnológicos da humanidade, procede-se às análises dos textos selecionados, procurando apontar e relacionar o pensamento dos escritores, provando que idéias sobre os avanços científicos e tecnológicos estão presentes na produção literária de cada um. Por fim, após o confronto estabelecido durante todo o trabalho entre o pensamento e o posicionamento dos escritores, discutese o papel da literatura no desenvolvimento e avanço da humanidade.

A modernização da Marinha do Brasil se faz necessária em face de fatores relacionados à obsolescência dos meios, incremento tecnológico e outros incentivos de ordem doméstica e internacional. No caso brasileiro, apesar de haverem diversos programas de reaparelhamento desde a proclamação da república, os programas de maior envergadura e que geraram resultados importantes ocorreram em 1910, 1977 e 2007. O Reaparelhamento da Marinha do Brasil responde principalmente a incentivos de ordem sistêmica e doméstica. A sua efetividade é o principal objetivo de um programa de incremento material, e muito mais do que orientação à defesa da pátria, os objetivos expressos na grande estratégia de um país devem preceder a decisão de repotencialização da Força. O trabalho utiliza a metodologia histórico comparativa, por meio do método denominado Process Tracing. Essa incipiente metodologia permite verificar as evidências ao longo de processos e verificar a hierarquização de cada fator por meio de testes empíricos baseados na minuciosa descrição histórica dos casos. As teorias realistas buscam explicações para o comportamento dos países em relação ao Sistema Internacional. O ambiente anárquico em que se encontram os países definem suas preferências, mas o aspecto doméstico responde fortemente a esses incentivos sistêmicos e justifica as diferentes conduções de políticas externas em ambiente similar. A teoria neoclássica considera os fatores domésticos como intervenientes neste processo. Por meio do modelo desenvolvido por Schweller (2006), este trabalho verificou que o aspecto sistêmico é determinante para o reaparelhamento da Marinha, e no âmbito doméstico o consenso e coesão das elites são necessárias, entretanto a coesão social passou de coadjuvante a uma das condições necessárias a partir do início do século XXI no processo de reaparelhamento.

Based on the presupposition that the arts in the West always counted on resources, supports, and devices pertaining to its time context, an reflection is intended regarding the scenic compositions mediated by digital technologies do. Such technologies are inserted in the daily routine, also composing artistic experiments, thus playing a dialogical role with the art/technology intersection. Therefore, the proposal is to investigate what relationships are established in the contemporary theatrical scene from the contagion by digital technologies, aiming at establishing this parallel through a dialogue with the authors discussing the subject, and also based on the group practices having technological resources as a determinant factor in their plays. Furthermore, a reflection should be made on the scene that incorporates or is carried out in intermediatic events, analyzing how digital technologies (re)configure compositional processes of the plays by GAG Phila7, in the city of São Paulo/SP. For such, the dissertation is organized in three sections comprising four moments, to wit: brief overview of the field, contextualization, poetic analysis and synthesis. Qualitative methods are used as the methodological proposal: semi-structure interview, note and document taking (program, website, playing book, disclosure material for advertising text, photographs, and videos). Within the universe of qualitative research, it works with the epistemological perspective of the Gadamer philosophical hermeneutics. The possibilities allowed by the double virtual (Internet/web) generated a type of theater with another material basis and new forms of organization and structure, being possible to perceive that such technological advances and the arts are mutually contaminated, generating a dislocation in the logics of theatrical composition, movement beginning with the artistic vanguards, gradually intensified, thus offering new possibilities of constructions and hybridization of the of the most different possible types. Experiment ―Profanações_superfície de eventos de construção coletiva‖, idealized by Phila7 is inserted in this perspective. Object of the discussion of such research, the experiment works with possible poetics arising from the intersection with the digital technologies, aiming at identifying and problematizing the challenges from the technological evolution and expansion in a scenic context

The development of new materials to fill the demand of technological advances is a challenge for many researchers around the world. Strategies such as making blends and composites are promising alternatives to produce materials with different properties from those found in conventional polymers. The objective of this study is to evaluate the effect of adding the copolymer poly(ethylene methyl acrylate) (EMA) and cotton linter fibers (LB) on the properties of recycled poly(ethylene terephthalate) (PETrec) by the development of PETrec/EMA blend and PETrec/EMA/LB blend composite. In order to improve the properties of these materials were added as compatibilizers: Ethylene - methyl acrylate - glycidyl methacrylate terpolymer (EMA-GMA) and maleic anhydride grafted polyethylene (PE-g-MA). The samples were produced using a single screw extruder and then injection molded. The obtained materials were characterized by thermogravimetry (TG), melt flow index (MFI) mensurements, torque rheometry, pycnometry to determinate the density, tensile testing and scanning electron microscopy (SEM). The rheological results showed that the addition of the EMA copolymer increased the viscosity of the blend and LB reduces the viscosity of the blend composite. SEM analysis of the binary blend showed poor interfacial adhesion between the PETrec matrix and the EMA dispersed phase, as well as the blend composite of PETrec/EMA/LB also observed low adhesion with the LB fiber. The tensile tests showed that the increase of EMA percentage decreased the tensile strength and the Young s modulus, also lower EMA percentage samples had increased the elongation at break. The blend composite showed an increase in the tensile strength and in the Young`s modulus, and a decrease in the elongation at break. The blend formulations with lower EMA percentages showed better mechanical properties that agree with the particle size analysis which showed that these formulations presented a smaller diameter of the dispersed phase. The blend composite mechanical tests showed that this material is stronger and stiffer than the blend PETrec/EMA, whose properties have been reduced due to the presence of EMA rubbery phase. The use of EMA-GMA was effective in reducing the particle size of the EMA dispersed phase in the PETrec/EMA blend and PE-g-MA showed evidences of reaction with LB and physical mixture with the EMA

The method "toe-to-heel air injection" (THAITM) is a process of enhanced oil recovery, which is the integration of in-situ combustion with technological advances in drilling horizontal wells. This method uses horizontal wells as producers of oil, keeping vertical injection wells to inject air. This process has not yet been applied in Brazil, making it necessary, evaluation of these new technologies applied to local realities, therefore, this study aimed to perform a parametric study of the combustion process with in-situ oil production in horizontal wells, using a semi synthetic reservoir, with characteristics of the Brazilian Northeast basin. The simulations were performed in a commercial software "STARS" (Steam, Thermal, and Advanced Processes Reservoir Simulator), from CMG (Computer Modelling Group). The following operating parameters were analyzed: air rate, configuration of producer wells and oxygen concentration. A sensitivity study on cumulative oil (Np) was performed with the technique of experimental design, with a mixed model of two and three levels (32x22), a total of 36 runs. Also, it was done a technical economic estimative for each model of fluid. The results showed that injection rate was the most influence parameter on oil recovery, for both studied models, well arrangement depends on fluid model, and oxygen concentration favors recovery oil. The process can be profitable depends on air rate

In the current systemic crisis, economic policy is directed to correct the consequences of the functioning of this metabolism, but within the limits of the capital. From this perspective, decision makers propose trade policies, agricultural and industrial to ensure conditions for economic growth. However, as a dead end, there is failure of the State in giving efficacy to the operation of all segments of the economy, especially given the budget constraint. Public managers are forced to seek external resources, resuming the cycle of political allegiance to the interests of international financial and banking representatives, installed in so-called multilateral. The complex ideological capital comes into play in trying to convince society that the paths taken by governments are inevitable, and that capitalism can be "humanized", even with the realization of the growing inequalities caused by historical irrationalism of the production process of capital . In this sense, emerging concepts that attempt to demonstrate the compatibility of the system to real human needs. This ideological offensive is intended to legitimize the capital. The so-called third sector has a special highlight with the concept of corporate social responsibility. It creates a political environment in which the inevitable mix-up with new illusions offered by and often funding the metabolism of capital in order to perpetuate this system. In this context, political elites, and considerable portions of the academy, embark on "waves of capitalist optimism," while the sociometabolismo capital expands its historical limits, driving forces postponing their collapse, but that cause human suffering and ecological stress. Wars are disseminated to strengthen the deadly war industry and the automobile industry; and devastating the environment of which depends the capital system. In this scenario disassemble, propositions emerge around a "new social pact" in order to minimize the adverse effects of the dynamics of reproduction of capital. The business class is called to exercise its role through the discourse that appeals to social responsibility programs, in order to intervene directly in the "social question". The core of this research is precisely this point. Although there is considerable scholarship on the phenomenon of Social Responsibility and Corporate Citizenship, there is also an evident lack of this approach focused on the banking sector in Brazil. The importance of rentier capital increased ownership of shares in the wealth produced by all of Brazilian society, justifies a sociological research project on Social Responsibility in the domestic financial sector. In this sense, it was decided to perform a dynamic approach to the "Corporate Citizenship" in the banking industry, specifically in the Bank of Brazil. As this is a key institution, is important analyze of the impacts of this strategy fetish of capitalist reproduction, in order to evaluate the social legitimization of rentier capital in Brazil. In this scenario of the abundance of the discourse on social responsibility there exist a progressive impoverishment of professional work in this segment in Brazil. There is a dramatic mismatch between rhetoric and practice because of the trend of deepening vulnerability of the working conditions of the Brazilian bank worker, from the 1990's. In the specific case of the Bank of Brazil, the first initiative of the institution was to conform to the principles of the UNO and the Ethos Institute, aiming to align their domestic policies to this new strategy of domination of capital. The purpose is to place the Bank in the ideological sphere of corporate social responsibility, just as with its partners in the private financial intercapitalist competition. Indeed, in the internal ambit of the Bank of Brazil, there is a policy to adjust its functional segments to the doctrine of Social Corporate Responsibility. The concepts of this doctrine is presented as something inexorable. There are no alternatives. The Bank of Brazil operates in a highly competitive market, the segment featuring the dominance of financial capital accumulation today. For this reason it can not fail to incorporate the technological advances organizational. For employees there is no alternative but to adapt to this new set of ideas proposed by the metabolism of capital

The present study has as goal to analyze the aplicability of the computational technology as mediator in the english-speaking teaching in the Centro Federal de Educação Tecnológica do Rio Grande do Norte-CEFET/RN. The object of study was centered in the use of the computer incorporated in the teaching of English by four institution groups. The research was ruled metodologically in the study of case, adopting a qualitative and quantitative boarding of interpretative-reflexive mark. We support ourselves on a bibliographical literature revision that cares of the use of the computational technology matter into the class-room, aiming an education new practice, regarding the current reality conceptions in what we live in the technological education. We also use a referencial for a pedagogical action, trying to offer subsidies for a practice that provides the knowledges generation through the interaction, aiming a subject reflexive and critical education. For materialization of this study, we used esrutuctured action, as interviews for the teachers and students, besides the observations of the dayly in class-room, in order to get the necessary datas for analysis. During this study, we oserved that the use of the computer, while pedagogical support instrument in the english-speaking teaching, has acted like mediator of the teaching-learning process. The results demonstrate use of the computer use has been each more a practice adopted by other institution languages teachers. The conclusions confirm the hypothesis showed at the beginning of the work and evidence that the teachers are warden of forming thinking, reflexive and critical subjects. For that, they need to be prepared to face situations in which they can take the pedagogical practice to tune with the technological advances, consequently providing an effective technological education

Despite of the technological advances that favor the transplant process, there are issues of effectiveness of care necessary for the maintenance of potential organ donors with brain death, which contribute to the no realization of transplants of organs and tissues of these patients. It is presupposed that the problems could be related to perceptions and understandings that the professionals of the units of internment have about the care required by the diagnosis of brain death. The aim of this study was to understand the meaning of the nursing care of the potential organ donor with brain death to the nursing staff. Descriptive study with qualitative approach guided by Action Science Theory and the critic-reflexive research methodology accomplished with five nurses and 19 nursing technicians from Operative Rehabilitation Center in a public hospital at Natal / RN, Brazil, between March and May 2013. Data were collected through semi-structured interviews with individual reflection about the care and through group interview, after approval by the Ethics and Research Committee, CAAE No.: 04255612.7.0000.5537. The analysis was performed in a thematic way according to Bardin. During the group meeting the participants were driven in a discussion about the need for change and how to perform them. The results indicate that the professionals actions are consistent with those required for maintenance of potential organ donors, although the material and human resources are not adequate. That situation leads the professionals to develop a meaning of care as one labor more, demanding more than they can give. They express beliefs and feelings concerning the hope that their care brings a greater good that is to save lives. The reflection for a possible change of action was difficult to accomplish due to professionals not to be able to self evaluate, what lead to direct your changes suggestions for other team members. It is concluded that the care provided to these patients is a difficult care, evidenced by suffering both death situation of the person cared and pain of their families, as the dehumanizing conditions of work, helping themselves to keep distance from patients to not suffer so much. The knowledge impregnated in their act, are scientific, ethical, aesthetic and personal kind with a predominance of the scientific followed by the personal. The study was also relevant to the practice of nursing in maintaining the potential donor, in that it allowed the identification of the knowledge used by nurses in their care practice and the meaning understanding of the professionals on the care provided, as a good action that brings satisfaction when the transplanting is executed. Other experiences are suggested with the critic-reflexive research methodology, both in research as in teaching nursing

A participação do Brasil no mercado externo de frutas tem aumentado consideravelmente e com potencial para crescer ainda mais. A constante ascensão dos dados de exportação brasileira é resultado da combinação de avanços tecnológicos do setor produtivo e de acesso a novos mercados consumidores. A caramboleira apresenta-se como uma excelente opção de cultivo de frutas exóticas, com grande potencial para atender ao mercado interno e às exportações. Assim, objetivou-se avaliar a marcha de absorção e de acúmulo de nutrientes em mudas de caramboleiras cultivadas em solução nutritiva. O experimento foi realizado em parcelas subdivididas, sendo utilizadas como parcela as duas cultivares de caramboleira ('B-10' e 'Golden Star') e, como subparcelas, cinco épocas de coleta de plantas, realizadas aos 208; 233; 258; 283 e 308 dias após o transplantio para a solução nutritiva. O delineamento foi inteiramente casualizado, com três repetições. As mudas foram cultivadas em vasos (8L) com solução nutritiva (pH=5,5 ± 0,5), com aeração. O experimento iniciou-se em 24-08-2005. Nos diferentes órgãos das mudas (folhas, caule e raízes), determinaram-se a marcha de absorção, o acúmulo de nutrientes e os índices nutricionais. Não houve diferenças no acúmulo de nutrientes entre as mudas de caramboleira de ambas as cultivares, sendo a ordem decrescente dos nutrientes em cada muda de 'B-10', no final do período experimental: N > K > Ca > Mg > S > P > Fe > Mn > B > Cu > Zn. Para a 'Golden Star', a ordem foi: N > K > Ca > Mg > P > S > Fe > Mn > B > Cu > Zn. Para as duas cultivares, o acúmulo médio foi maior nas folhas > caule > raízes. O período de maior exigência para 'B-10' foi entre 208 - 233 e, para 'Golden Star', entre 233 - 283 dias após o transplantio. As diferentes taxas de acumulação líquida dos nutrientes, nos diferentes órgãos da caramboleira, nem sempre acompanharam a taxa de acumulação de nutrientes do respectivo órgão.

The seismic method is of extreme importance in geophysics. Mainly associated with oil exploration, this line of research focuses most of all investment in this area. The acquisition, processing and interpretation of seismic data are the parts that instantiate a seismic study. Seismic processing in particular is focused on the imaging that represents the geological structures in subsurface. Seismic processing has evolved significantly in recent decades due to the demands of the oil industry, and also due to the technological advances of hardware that achieved higher storage and digital information processing capabilities, which enabled the development of more sophisticated processing algorithms such as the ones that use of parallel architectures. One of the most important steps in seismic processing is imaging. Migration of seismic data is one of the techniques used for imaging, with the goal of obtaining a seismic section image that represents the geological structures the most accurately and faithfully as possible. The result of migration is a 2D or 3D image which it is possible to identify faults and salt domes among other structures of interest, such as potential hydrocarbon reservoirs. However, a migration fulfilled with quality and accuracy may be a long time consuming process, due to the mathematical algorithm heuristics and the extensive amount of data inputs and outputs involved in this process, which may take days, weeks and even months of uninterrupted execution on the supercomputers, representing large computational and financial costs, that could derail the implementation of these methods. Aiming at performance improvement, this work conducted the core parallelization of a Reverse Time Migration (RTM) algorithm, using the parallel programming model Open Multi-Processing (OpenMP), due to the large computational effort required by this migration technique. Furthermore, analyzes such as speedup, efficiency were performed, and ultimately, the identification of the algorithmic scalability degree with respect to the technological advancement expected by future processors

Particularly in Braziland in Rio Grande do Norte, companies manufacturing red ceramic, play an important role as agents of development to study the region Seridó- RN, specific place for carrying out the research. It is observed in this region a concentration of red ceramic industries of small size, which, despite its importance in the ceramic, they are unable to enjoy or use the new forms of administrative management and technological advances designed and offered by universities, centers of research and projects of governments, remained almost entirely outside the progress and modernization, technological and administrative. These companies still have outdated technology, and management processes, providing quality problems and standardization of end products. Upon these conditions are the companies going through crisis and struggling to survive alone and without assistance. The region of Seridó-RN, lets make a detailed case study of red ceramic companies in the region proposed from the existing theoretical and actual lifting of the condition of the product manufacturing red ceramic, allowing through this overview of the implementation of collect samples of raw materials, allowing the study of each ceramic industry that contributed to the participation of the research, which was determined parameters such as: analysis of the physical, chemical and technological properties of raw materials, characterization of the processes used, raising the technological resources considering equipment, machinery, supplies, raw materials and facilities available and its organization by type of products from companies involved in this study. The methodology consists of the following steps: collection of raw material, crushing and screening, characterization of raw materials (liquid limit, chemical analysis, mineralogical analysis, differential thermal analysis, sieve analysis), mixing, forming, cutting, drying and burning of ceramic bodies and bodies of evidence. The results showed that it was clay with distinct characteristics with respect to plasticity. With respect to the different compositions of mixtures of ceramic masses, we conclude that the ceramic properties showed a direct proportionality with increasing fraction of the clay not plastic. However, the compositions of the masses studied proved to be the most appropriate for the types of simulated clay for use in ceramics. Adopted in the ceramic processing made it possible to obtain products the resulted in consistent properties, and in some cases even exceeding the requirements of technical studies and standard-Brazilian clays to obtain ceramic products such as tiles, bricks and tiles to floor. Based on the discussions from the results obtained in the various processing steps of this work, one can draw conclusions according to the physico-chemical and mineralogical properties of raw materials, the properties of ceramic products burned and analysis. This work may be used by other researchers, private companies and governmental organizations, undergraduate students and graduate, can develop studies and future research to: develop projects to modify the furnaces; mapping projects develop and rationalize the exploitation of raw materials ;promoting reforestation and forest management; develop reduction projects and recovery of waste; develop training projects in manpower sector, and develop security projects, improving the conditions of work in the area pottery
