A assistência estudantil e as cotas sociais nas universidades estaduais do nordeste: as faces do acesso ao direito

This paper discusses about the higher education in Brazilian society highlighting the struggle of the working class, as concerning the access to public universities, as well as highlights the contradictions implicit in social quotas adopted by Higher Education Institutions (HEIs) . The aim of this paper is on presenting the analysis of student assistance of the state universities in the Northeast that adopt quotas as social criteria of access for its students , presenting investigative locus as the following universities : UERN , UEPB , UPE and UNEAL . The paper presents the results of a qualitative study , based on a documentary analysis , based on dialectical and historical materialism in which she performed the reading of data from the following analytical categories: Higher Education, Social Quotas and Student Assistance. As main results, it is emphasized that the implementation of quotas as a means of access to higher education was not decisive for the form of planning and implementation of student assistance the university investigated; latent heterogeneity is that universities deal with actions to support student residence. And it is this heterogeneity and the variation in the conduct and understanding of student assistance , reflecting the lack of prioritization with the actions of the context of HEIs ; support programs are to stay focused on central campuses which are located the administrative offices of the universities, penalizing students enrolled in advanced units; also highlight that there is no link between the programs and projects related to student assistance with actions related to teaching, research and extension in universities investigated , which ultimately characterize the student assistance as an isolated action and punctual

Projeto de Sistemas Integrados de Propósito Geral Baseados em Redes em Chip Expandindo as Funcionalidades dos Roteadores para Execução de Operações: A plataforma IPNoSys

It bet on the next generation of computers as architecture with multiple processors and/or multicore processors. In this sense there are challenges related to features interconnection, operating frequency, the area on chip, power dissipation, performance and programmability. The mechanism of interconnection and communication it was considered ideal for this type of architecture are the networks-on-chip, due its scalability, reusability and intrinsic parallelism. The networks-on-chip communication is accomplished by transmitting packets that carry data and instructions that represent requests and responses between the processing elements interconnected by the network. The transmission of packets is accomplished as in a pipeline between the routers in the network, from source to destination of the communication, even allowing simultaneous communications between pairs of different sources and destinations. From this fact, it is proposed to transform the entire infrastructure communication of network-on-chip, using the routing mechanisms, arbitration and storage, in a parallel processing system for high performance. In this proposal, the packages are formed by instructions and data that represent the applications, which are executed on routers as well as they are transmitted, using the pipeline and parallel communication transmissions. In contrast, traditional processors are not used, but only single cores that control the access to memory. An implementation of this idea is called IPNoSys (Integrated Processing NoC System), which has an own programming model and a routing algorithm that guarantees the execution of all instructions in the packets, preventing situations of deadlock, livelock and starvation. This architecture provides mechanisms for input and output, interruption and operating system support. As proof of concept was developed a programming environment and a simulator for this architecture in SystemC, which allows configuration of various parameters and to obtain several results to evaluate it

Geração automática de hardware a partir de especificações formais: estendendo uma abordagem de tradução

Removing inconsistencies in a project is a less expensive activity when done in the early steps of design. The use of formal methods improves the understanding of systems. They have various techniques such as formal specification and verification to identify these problems in the initial stages of a project. However, the transformation from a formal specification into a programming language is a non-trivial task and error prone, specially when done manually. The aid of tools at this stage can bring great benefits to the final product to be developed. This paper proposes the extension of a tool whose focus is the automatic translation of specifications written in CSPM into Handel-C. CSP is a formal description language suitable for concurrent systems, and CSPM is the notation used in tools support. Handel-C is a programming language whose result can be compiled directly into FPGA s. Our extension increases the number of CSPM operators accepted by the tool, allowing the user to define local processes, to rename channels in a process and to use Boolean guards on external choices. In addition, we also propose the implementation of a communication protocol that eliminates some restrictions on parallel composition of processes in the translation into Handel-C, allowing communication in a same channel between multiple processes to be mapped in a consistent manner and that improper communication in a channel does not ocurr in the generated code, ie, communications that are not allowed in the system specification

Evolving Future Internet clean-slate Entity Title Architecture with quality-oriented control-plane extensions

A Internet atual vem sofrendo vários problemas em termos de escalabilidade, desempenho, mobilidade, etc., devido ao vertiginoso incremento no número de usuários e o surgimento de novos serviços com novas demandas, propiciando assim o nascimento da Internet do Futuro. Novas propostas sobre redes orientadas a conteúdo, como a arquitetura Entidade Titulo (ETArch), proveem novos serviços para este tipo de cenários, implementados sobre o paradigma de redes definidas por software. Contudo, o modelo de transporte do ETArch é equivalente ao modelo best-effort da Internet atual, e vem limitando a confiabilidade das suas comunicações. Neste trabalho, ETArch é redesenhado seguindo o paradigma do sobreaprovisionamento de recursos para conseguir uma alocação de recursos avançada integrada com OpenFlow. Como resultado, o framework SMART (Suporte de Sessões Móveis com Alta Demanda de Recursos de Transporte), permite que a rede defina semanticamente os requisitos qualitativos das sessões para assim gerenciar o controle de Qualidade de Serviço visando manter a melhor Qualidade de Experiência possível. A avaliação do planos de dados e de controle teve lugar na plataforma de testes na ilha do projeto OFELIA, mostrando o suporte de aplicações móveis multimídia com alta demanda de recursos de transporte com QoS e QoE garantidos através de um esquema de sinalização restrito em comparação com o ETArch legado

Democratização do acesso a água no semi-árido: o caso da comunidade rural de Pendências dos Emídios no município de Serrinha/RN

Brazil lives a time of experimentation and maturity as it pertains to managing the use of water, which comes institutionalising increasingly social participation. In Rio Grande do Norte, since 1997, the government has been developing actions accordingly, through the State Department of Water Resources, which has implemented a programme of adutoras within the State and created Water Users Associations, in the installation of dessalinizadores for places where the Adutora was not necessary or not yet arrived, so that should be managed by communities through associations of users. Since 2003, Civil Society Organisations - CSOs come through ASA - Articulation in the Semi-arid Brazilian, implementing the P1MC - Program of Training and Mobilization for Social Living with the Semi-Arid (One Million Rural Cisternas), in its third year of implementation in Rio Grande do Norte, in the spirit of working together with the semi arid. In the municipality of Serrinha / RN which incorporates the Semi-arid region, we find in the rural community of Pendêcias dos Emídios the experience of the State and Civil Society, which referred to a discussion about the environmental sustainability of these initiatives. The general objective of this work is to examine the strategies for participatory management in the use and access to water in the community of Pendêcias dos Emídios of the municipality of Serrinha / RN, to understand how those experiences can contribute to environmental sustainability. The methodology used envolvel bibliographic research in categories involving each article, the analysis of the terms of reference of each strategy as part of the documentary research, the application forms covering 40 families benefited, and interviews based on comprehensive analysis of the speech. This study is divided into 02 articles, where the first is a discussion held on collective action and environmental sustainability, and the second is held a discussion about the sustainability of the initiatives underway to access water. The results of the discussion held on 02 articles that had their empirical built from the experience of the Commonwealth of Pendências dos Emídios revealed how far will the ability of the State to promote collective action and the limitations of the perception of sustainability that permeates these initiatives in the search for democratic access to water in semi-arid

Algoritmos e Arquiteturas VLSI para Detectores MIMO com Decisão Suave

The use of Multiple Input Multiple Output (MIMO) systems has permitted the recent evolution of wireless communication standards. The Spatial Multiplexing MIMO technique, in particular, provides a linear gain at the transmission capacity with the minimum between the numbers of transmit and receive antennas. To obtain a near capacity performance in SM-MIMO systems a soft decision Maximum A Posteriori Probability MIMO detector is necessary. However, such detector is too complex for practical solutions. Hence, the goal of a MIMO detector algorithm aimed for implementation is to get a good approximation of the ideal detector while keeping an acceptable complexity. Moreover, the algorithm needs to be mapped to a VLSI architecture with small area and high data rate. Since Spatial Multiplexing is a recent technique, it is argued that there is still much room for development of related algorithms and architectures. Therefore, this thesis focused on the study of sub optimum algorithms and VLSI architectures for broadband MIMO detector with soft decision. As a result, novel algorithms have been developed starting from proposals of optimizations for already established algorithms. Based on these results, new MIMO detector architectures with configurable modulation and competitive area, performance and data rate parameters are here proposed. The developed algorithms have been extensively simulated and the architectures were synthesized so that the results can serve as a reference for other works in the area

Universalização do acesso à saúde e regulação dos planos privados de assistência à saúde: a atuação regulatória da ANS como instrumento de harmonia contratual e viabilização do papel suplementar da iniciativa privada na efetivação do direito social à saúde

While essential to human nature, health and life have been protected since ancient times by various areas of knowledge, particularly by the Law, given its dynamics within the regulation of social interactions. In Brazil, health has been granted major importance by the Federal Constitution of 1988, which, disrupting the dictatorial authoritarianism, inaugurating a Social State and focusing on the values of freedom and human dignity, raises health to the condition of a social right, marked predominantly by an obligational bias directed, primarily, to the State, through the enforcement of public policies. Although, given the limitation of the State action to the reserve for contingencies, it turns clear that an universalizing access to public health is impossible, seen that the high cost of medical provisions hinders the State to meet all the health needs of the rightholders. As a result of the inefficiency of the State, the effort of the Constituent Assembly of 1988 in creating a hybrid health system becomes nuclear, which, marked by the possibility of exploration of healthcare by the private initiative, assigns to the private enterprise a key role in supplementing the public health system, especially through the offer of health insurance plans. At this point, however, it becomes clear that health provisions rendered by the private agents are not unlimited, which involves discussions about services and procedures that should be excluded from the contractual coverage, for purposes of sectoral balance, situation which draws the indispensability of deliberations between Fundamental Rights on one hand, related to the protection of health and life, and contractual principles on the other hand, connected to the primacy of private autonomy. At this point, the importance of the regulation undertaken by the ANS, Brazilian National Health Agency, appears primordial, which, by means of its seized broad functions, considerable autonomy and technical discretion, has conditions to implement an effective control towards the harmonization of the regulatory triangle, the stability and development of the supplementary health system and, consequently, towards the universalization of the right to health, within constitutional contours. According to this, the present essay, resorting to a broad legislative, doctrinal and jurisprudential study, concludes that economic regulation over the private healthcare sector, when legitimately undertaken, provides progress and stability to the intervening segment and, besides, turns healthcare universalization feasible, in a way that it can not be replaced efficiently by any other State function.

Conhecimento de si e unidade: considerações sobre a alma em Plotino

L'obiettivo di questa tesi è quello di sviluppare una analisi dell'idea dell'immortalità dell'anima dalle Enneadi di Plotino attraverso la comprensione del discorso dell'anima come eterno, e unità-pluralità ricerca di semplicità con la Uno sulla temporalità del corpo multiple. Per fare ciò, abbiamo iniziato cercando di analizzare brevemente le plotinianas ipostasi (l'Uno, lo spirito e l'anima) per stabilire meglio le basi del pensiero di Plotino quando si discute l'idea dell'anima e la sua immortalità. Cerchiamo di esaminare il pensiero epistéme di Plotino e la sua dialettica, al fine di sviluppare una comprensione del rapporto tra materia e forma sensibile e intelligibile. In questo modo, si sviluppa nelle Enneadi di Plotino il ruolo fondamentale del Logos e il Logoi nella formazione dell'anima. Analizziamo anche la processione (Proódos) e ritorno (Epistrophé) le implicazioni degli aspetti dell'eternità sulla purificazione dell'anima nella temporalità del corpo. Cerchiamo in ultima analisi, l'idea dell'immortalità dell'anima dalla conoscenza stessa immortalità sulla semplicità di Colui, cioè, l'ultima volta che la ricerca della conoscenza di sé dalla dimenticanza di sé per è solo con l'Uno: il "Elimina ogni cosa" (Aphele pánta).

Projeto de absorvedores de micro-ondas integrados com superfícies seletivas em frequência

Considering the fact that, the use of wireless communication systems has grown too fast, investigations concerning absorbers of electromagnetic waves has called closer attention of researchers. It is applicable from indoor systems to military applications. Paralleling with this growth, some extremely relevant investigations through Frequency Selective Surfaces (FSS) allows its filter property to be applicable in several systems, for example: reflector antennas, band-pass radomes, and absorbers, which are the main objective of this work. Therefore, the main goal of this work concerns to design micro-waves absorbers through FSS. Thus, the methodology consists basically in two steps: the first step concerns a theoretical and numerical analysis of the structures involved in the process of absorption, the second step, the analysis of the cascaded structures. In order to carry out the analysis, the Equivalent Circuit Method will be used. This method provides characteristics of transmission from the structure, for a plane wave incidence and it requires an extremely limited computing resource in relation if compared to full wave analyses method. Hence, it is useful to allow fast predictions of the development of the structures. Furthermore, a spreading matrix will be used in order to cascade the conductive FSS and the resistive FSS achieving absorption characteristics in the designed band. The experimental results used for the analysis are found in the literature due to the difficulty of building soon, given that it is not a simple construction technique. To conclude, a mathematical development through the Equivalent Circuit Method of a FSS modeling with cross-dipole geometry and a resistive FSS will be presented, as well as the cascading involving the two structures. The same setting is used with a square loop geometry. Besides it, the next steps will be discussed in the conclusion.

Abordagem da ergonomia para avaliação do treinamento simulado das equipes de resposta à emergência em lançamentos de veículos aeroespaciais

This dissertation introduces a study that aims to analyze the simulated training of emergency teams and proposes recommendations for the current training system in order to improve the collective skills and resilience of these teams when facing possible critical situations, triggered by possible accident occurrences during aerospace vehicle launching operations in the Barreira do Inferno Launch Center in Parnamirim / RN. This is a field, exploratory, descriptive, explanatory, and a case study with a qualitative approach. Therefore, we adopted the ergonomics approach, using the situated method of ergonomic work analysis (AET), combining observational and interactive methods. The relevance of this research is characterized by the contributions to minimize the human and material hazzards resulting from possible accidents in these operations, the scientific contribution of the AET for simulated emergency training analysis in the launching operations of aerospace vehicles - which are complex and involve risk of accidents - and consequently, the scientific contribution to the current process of recovering the Brazilian Space Program. The survey results point to problems of various kinds in the current simulated training system which compromise the safety of the operations. These problems are grouped into four categories: technological, organizational, team training and from the activity itself, regarding more specifically communication and cooperation (among the team members and these ones with other sectors involved in the launching operation) and regarding the coordination of actions. We propose: a) a new training model, from the creation and application of scenarios based on postulated abnormalities, which could simulate real critical situations, in order to train and improve the skills of the emergency response teams especially in terms of communication, coordination and cooperation; b) restructuring and reorganizing the current training system, based on the formal establishment of a managing staff, on the clear division of responsibilities, on the standardization of processes, on the production of management indicators, on the continuous monitoring, on the feedback from trainees about the quality of the training and on the continuing and frequent training of emergency teams.

Caracterização de superfícies seletivas de frequência de periódicas e não-periódicas

The past years have seen a great interest in the use of frequency selective surfaces (FSS), as spatial filters, in many microwave applications. Among these, we highlight applications in telecommunication systems (such as satellite communications and radar), high gain antennas (combined with planar antennas) and (home and industrial) microwave ovens. The FSS is usually composed of two-dimensional periodic arrays, with equally spaced elements, which may be metallic patches (printed on dielectric substrates) or aperture (holes in thin metal surfaces). Using periodic arrays, the FSS have been able to meet the demands of the telecommunications industry. However, new demands are finding technological limitations. In this context, adverse filtering requirements have forced designers to use FSS optimization methods to find specific formats of FSS elements. Another alternative that has been used to increase the selectivity of the FSS is the cascaded FSS, a simple technique that has as main drawback the increased dimensions of the structure, as well as its weight. This work proposes the development of a new class of selective surfaces frequency (FSS) composed of quasi-periodic (or non-periodic) arrangements. The proposed FSS have no array periodicity, in relation with the spatial position of their elements. The frequency responses of these structures were simulated using commercial softwares that implement full-wave methods. For the purpose of validation of this study, FSS prototypes were built and measured, being possible to observe a good agreement between simulated and measured results. The main conclusions of this work are presented, as well as suggestions for future works.

Avaliação do acesso aos serviços de reabilitação física para vítimas de acidentes de trânsito: caminhos para melhoria da qualidade do sistema de saúde

The Physical Rehabilitation services (PR) are of fundamental importance in combating the global epidemic of Traffic Accidents (TA). Considering the numerous physical and social consequences of the survivors, quality problems in access to PR are a hazard to recovery of victims. It is necessary to improve the management of quality of services, assessing priority dimensions and intervening in their causes, to ensure rehabilitation available in time and suitable conditions. This study aimed to identify barriers to access to rehabilitation considering the perception of TA victims and professionals. The aim is also to estimate the access to rehabilitation and their associated factors. This is a qualitative and quantitative study of exploratory nature developed in Natal / RN with semi-structured interviews with 19 health professionals and telephone survey to 155 victims of traffic accidents. To explore barriers to access the speeches were transcribed and analyzed using the Alceste software (version 4.9). During the interviews used the following guiding question: “What barriers hinder or prevent access to physical rehabilitation for victims of traffic accidents?”. The names of classes and axes resulting from Alceste was performed by ad hoc query to three external researchers with subsequent consensus of the most representative name of analysis. We conducted multivariate analysis of the influence of the variables of the accident, sociodemographic, clinical and assistance on access to rehabilitation. Associations with p <0.20 in the bivariate analysis were submitted to logistic regression, step by step, with p <0.05 and confidence interval (CI) of 95%. The main barriers identified were: “Bureaucratic regulation”, “Long time to start rehabilitation”, “No post-surgery referral” and “inefficiency of public services”. These barriers were divided into a theoretical model built from the cause-effect diagram, in which we observed that insufficient access to rehabilitation is the product of causes related to organizational structure, work processes, professional and patients. Was constructed two logistic regression models: “General access to rehabilitation” and “Access to rehabilitation to public service”. 51.6% of patients had access to rehabilitation, and 32.9% in public and 17.9% in the private sector. The regression model “General access to rehabilitation” included the variables Income (OR:3.7), Informal Employment (OR:0.11), Unemployment (OR:0.15), Perceived Need for PR (OR:10) and Referral (OR: 27.5). The model “Access to rehabilitation in the public service” was represented by the “Referral to Public Service” (OR: 23.0) and “Private Health Plan” (OR: 0.07). Despite the known influence of social determinants on access to health services, a situation difficult to control by the public administration, this study found that the organizational and bureaucratic procedures established in health care greatly determine access to rehabilitation. Access difficulties show the seriousness of the problem and the factors suggest the need for improvements in comprehensive care for TA survivors and avoid unnecessary prolongation of the suffering of the victims of this epidemic.

OBJECTIVE: To dev elop and evaluate the use of a body adjustable device for training of peripheral venous catheterization for healthcare undergraduate students . METHODS: This study involved two phases: I) development of the innovative simulator and II) a controlled trial co mparing the performance of the body adjustable device in relation to the commercial simulator for the training of venipuncture skills. A total of 79 first - year medical students participated in the intervention phase, which consisted of pretest assessment, lecture on peripheral venous access, randomization into two groups according to the simulator used for training (Commercial Simulator and Experimental Simulator), real venipuncture procedure, post - test assessment and evaluation of satisfaction. RESULTS: Gr oups were homogeneous in age, sex, pre - test and post - test scores, attitudinal assessment and performance in performing the real venipuncture. Students from the Experimental Simulator group performed better on the filling of simulated records. At the end of the study, cognitive gain significantly increased in both groups. The degree of realism perceived by students was equivalent for two groups. A total of 85.7% of students rated the Experimental Simulator as good or excellent. CONCLUSIONS: Experimental simu lator proved to be a low cost alternative for the training of venipuncture skills in upper limb. The cognitive procedural and attitudinal performances of students who used the experimental simulator were similar to those observed in the group trained with commercial simulator.

Mel no asfalto: percepções do neutro nos contos de Caio Fernando Abreu

The work of Caio Fernando Abreu has a very vast and impressive thematic horizon , which is usually the core of the papers on the work of this author . This paper proposes to understand this characteristic of a more intricate point of view : perceive and analyze how the work of the author builds itself thematically , but mainly textually . I n other words , as the text enacts his own writing . From this it is noticeable how the text of Abreu plays with some senses through textual constructions that do not impose directly sense to the reader . Thus, the research sees in the chosen corpus , the collection Os dragões não conhecem o paraíso ( 2014 ), the neutral as proposed by the French essayist Roland Barthes (2003 a ). This neutral is understood by Barthes as a possibility to suspend the paradigms that constitute the sense, what exactly justifies the noticeable game in the work of Abreu . This game , to Roland Barthes , is precisely the literature. If the paradigm involves transforming the language , and all language expressions, in a way to propagate ideologies , the literature does not escape this fate . In order to escape this fate , you must fight the language internally ; we must play wit h the language . The neutral is the possibility of the game. Thus , the study sought neutral in Caio Fernando Abreu short stories , presenting it and analyzing it through " figures" which, for Barthes , is a way of perceiving the neut ral through texts , but not in a prescriptive manner. It was proposed , in the analysis , then understand the " Subjectivities ", the " Default ", the " Body " and " Disease " , for example, as possibilities of the game . Finally , in many Abreu’s work instances , the neutral is achieved by textual operations that are not in themselves neutral , but which achieve a " neutral effect ", which explains the game , the literature, in the texts of Caio Fernando Abreu .
