Prwncwyj: drama social e resolução de conflito entre os Apãniekra Jê-Timbira.

This work considers a ethnography boarding on the Apãniekra Jê-Timbira group of Central Brazil - leaving of a proposal of agreement of the group in perspectives of historical situations, analyzing its social organization from situational approaches. Taking the ethnography as main tool of production of data, the focus of the research takes dimension, when in the course of the ethnography situation, they come out, from certain events, social dramas that if ramify in crises, conflicts, faccionalismo. I analyze the mechanisms elaborated for the group to neutralize these dramas , such as the constitution of a tribal court , composites for native mediators and external mediators, dynamics ritual processes and politicians.

Modos projetuais de simulação: uso de ferramentas de simulação térmica no processo projetual de arquitetura

This thesis aims to describe and demonstrate the developed concept to facilitate the use of thermal simulation tools during the building design process. Despite the impact of architectural elements on the performance of buildings, some influential decisions are frequently based solely on qualitative information. Even though such design support is adequate for most decisions, the designer will eventually have doubts concerning the performance of some design decisions. These situations will require some kind of additional knowledge to be properly approached. The concept of designerly ways of simulating focuses on the formulation and solution of design dilemmas, which are doubts about the design that cannot be fully understood nor solved without using quantitative information. The concept intends to combine the power of analysis from computer simulation tools with the capacity of synthesis from architects. Three types of simulation tools are considered: solar analysis, thermal/energy simulation and CFD. Design dilemmas are formulated and framed according to the architect s reflection process about performance aspects. Throughout the thesis, the problem is investigated in three fields: professional, technical and theoretical fields. This approach on distinct parts of the problem aimed to i) characterize different professional categories with regards to their design practice and use of tools, ii) investigate preceding researchers on the use of simulation tools and iii) draw analogies between the proposed concept, and some concepts developed or described in previous works about design theory. The proposed concept was tested in eight design dilemmas extracted from three case studies in the Netherlands. The three investigated processes are houses designed by Dutch architectural firms. Relevant information and criteria from each case study were obtained through interviews and conversations with the involved architects. The practical application, despite its success in the research context, allowed the identification of some applicability limitations of the concept, concerning the architects need to have technical knowledge and the actual evolution stage of simulation tools

Eutrofização e capacidade de carga de fósforo de seis reservatórios a bacia do Rio Seridó, região semi-árida do Estado do RN

The eutrofization is a natural process of accumulation of nutrients in aquatic´s body that it has been accelerated for the human´s actives, mainly the related with the activities of camp, industrial and the inadequate disposition of the domestic sewage. The enrichment of the aquatic´s body with nutrients, mainly the nitrogen and the phosphorus, and the consequent proliferation of algae and Cyanobacteria can commit the quality of the water for the public provisioning, for the fish farming and for other ends. The problem becomes more critical when there is a shortage of water naturally as in the semi-arid area of the Brazilian northeast. Before that problem this work had as objective evaluates the trophic state of six reservoirs of the basin of River Seridó of Rio Grande of Norte and also estimate the capacity of load of match of the reservoir and risk probabilities based on the established limits by the resolution Conama 357/05. The results demonstrate that the six reservoirs are eutrofization, with concentration of total phosphorus and cloro a in the water upster to 50 e 12 μg l-1. The results show that space homogeneity exists in the state trophic of the reservoirs, but a significant variation interanual in function of the increase of the concentrations of nutrients and decrease of the transparency of the water with the reduction of the body of water accumulated in the reservoirs.The results of the simulation risk estocastic show that the reservoirs could receive annually from 72 to 216 Kg of P, assuming a risk of 10% of increasing in more than 30 μg l-1 the annual medium concentrations of total match in the water of these reservoirs. This load could be high in until 360 kg of P a year in case the managers assume a risk of 10% of increasing in more than 50 μg l-1 the annual medium concentrations of total phosphorus in the waters of these reservoirs

Desenvolvimento de um sistema misto de pasta à base de geopolímero e cimento portland para correção de perda de circulação

The materials engineering includes processes and products involving several areas of engineering, allowing them to prepare materials that fulfill the needs of various new products. In this case, this work aims to study a system composed of cement paste and geopolymers, which can contribute to solving an engineering problem that directly involves the exploitation of oil wells subject to loss of circulation. To correct it, has been already proposed the use of granular materials, fibers, reducing the drilling fluid or cement paste density and even surface and downhole mixed systems. In this work, we proposed the development of a slurry mixed system, the first was a cement-based slurry and the second a geopolymer-based slurry. The cement-based slurry was formulated with low density and extenders, 12.0 ppg (1.438 g/cm ³), showing great thixotropic characteristics. It was added nano silica at concentrations of 0.5, 1.0 and 1.5 gps (66.88, 133.76 and 200.64 L/m3) and CaCl2 at concentrations of 0.5, 1, 0 and 1.5%. The second system is a geopolymer-based paste formulated from molar ratios of 3.5 (nSiO2/nAl2O3), 0.27 (nK2O/nSiO2), 1.07 (nK2O/nAl2O3) and 13.99 (nH2O/nK2O). Finally, we performed a mixture of these two systems, for their application for correction of circulation lost. To characterize the raw materials, XRD, XRF, FTIR analysis and titration were performed. The both systems were characterized in tests based on API RP10B. Compressive strength tests were conducted after curing for 24 hours, 7 and 28 days at 58 °C on the cement-based system and the geopolymer-based system. From the mixtures have been performed mixability tests and micro structural characterizations (XRD, SEM and TG). The results showed that the nano silica, when combined with CaCl2 modified the rheological properties of the cement slurry and from the concentration of 1.5 gpc (200.64 L / m³) it was possible to obtain stable systems. The system mixture caused a change in the microstructure of the material by favoring the rate of geopolymer formation to hinder the C3S phase hydration, thus, the production of CSH phases and Portlandite were harmed. Through the mixability tests it can be concluded that the system, due to reduced setting time of the mixture, can be applied to plug lost circulation zones when mixed downhole

O processo de construção do problema da pobreza no Brasil

This text aims to undertake an analysis of the process of building the "problem of poverty" in Brazil. From a sociological approach on discourses and interpretations of poverty present in literary intellectuals representatives of some of the classics of Brazilian social thought, as well as in scientific works produced from mid-twentieth century and in the reports of various international organizations and national, such as the IMF, World Bank, MDS, IPEA, among others

Trabalho, pobreza e caridade: as ações do Padre Ibiapina nos sertões do Nordeste

This work started from an investigation concerning the process of education, moralization and disciplining of the poor in the backlands of the Brazilian Northeast region, in the second half of the 19th century, through the incorporation of the values of productive work. In order to do so, we took as our field of investigation the missions of Father José Antônio Pereira Ibiapina (1806-1883), in which an extensive work was developed, including the construction of twenty two (22) charity houses in the States of Rio Grande do Norte, Paraíba, Pernambuco, Ceará e Piauí, but also of weirs, churches, graveyards, hospitals and so forth. Given the socio-historical character of the research, we adopted qualitative methods of analysis and the following procedures: survey and analysis of documents, statute and internal rules that ordered the workings of the charity houses; biographies on Father Ibiapina and the missions‟ reports, as well as various sorts of publications on the missionary. Our study comprises his 27 year-period of missionary-religious activity (1856-1883), and undertakes an analysis on the topic of poverty, since the medieval Christian take on it until modernity, when it stops representing a value and becomes a problem to be solved through work. The socio-political context in which Ibiapina lived in the Northeast was marked by the consequence of droughts and economic crises in the region. The analysis of the documents indicates that, in the circumstances of political weakness and lack of interest for regional demands by the national political agenda, his missionary actions produced strong effects. Starting from an ethics of valorization of work, which combined modern and traditional elements, his actions set up disciplinary, moralizing and civil educational practices of the poor, founding, simultaneously, a pragmatic religious experience directed at the resolution of the problems caused by poverty. In that sense, we observe that such actions are connected to the broader process of moralization and education of the poor, but the analysis also suggests that their inscription into the social order articulated both forward as well as conservative aspects of the established system

Análise dos remanescentes de mata atlântica do Estado do Rio Grande do Norte : uma perspectiva em alta resolução

The habitat loss and fragmentation are considered the main threats to the biodiversity. These threats operate at the landscape level, which drives the need to manage entire landscapes, not just its components. Although systematic monitoring of the Atlantic Forest biome has been ongoing since the late eighties, current data on forest fragmentation for the sub-region of Pernambuco are practically nonexistent. This study aimed to map out, with high spatial resolution, the remnants of Atlantic forest in Rio Grande do Norte, and conduct a landscape level analysis. The results show that the landscape is highly fragmented, where about 13.6% to 17% of biome remains. Most of the fragments is less than 10 ha, while a few fragments have area larger than 100 ha. Although the high degree of fragmentation, the average distance between fragments found was small (128 m), this estimate is lower than has been observed for the biome (1440m). There is evidence that abrupt changes in the quantification of landscape structure can occur when one observes the fragmentation at high spatial resolution. The results presented here can be used in management actions, in order to make the scenario more conducive to maintaining biodiversity.

Tenho um problema: não gosto de ler! A formação do leitor literário construção compartilhada do prazer de ler

Esta tesis de maestría es el resultado de una investigación de carácter cualitativo y etnometodológico, realizada entre agosto de 2003 y junio de 2004, en una escuela primaria estatal, ubicada en Natal RN (Brasil). Su objetivo fue investigar la recepción de la lectura de literatura por parte de una maestra a la que, según reveló, no le gustaba leer y no se consideraba lectora de literatura. Se buscó investigar la mediación que le posibilitara llegar a ser lectora, comprender cuáles son los aspectos que influyen en la relación entre el lector en formación y la lectura de literatura, y verificar cómo repercute ese proceso de formación en la práctica docente de la maestra estudiada. Los procedimientos de investigación fueron aplicados con flexibilidad, tomando en cuenta el proceso de formación lectora de la docente. Los principales instrumentos utilizados fueron dos entrevistas semi-estructuradas, realizadas con la maestra, y notas de campo, que adquirieron el formato de un diario de investigación. En la primera etapa, fueron realizadas treinta sesiones de lectura, para posibilitar el acercamiento de la maestra a diferentes textos literarios. En la segunda etapa, fueron realizados tres encuentros de planificación con la maestra y cinco clases de lectura con sus alumnos. El análisis focaliza la recepción de la lectura literaria por parte de la maestra, abordando diferentes aspectos: su historia en relación con la lectura; la identificación, el contrato ficcional y la relación texto-vida; las previsiones y sus verificaciones; la mediación y el andamiaje brindados para introducir a la maestra en la cultura de la lectura. Se focaliza también la relación entre sus roles de lectora y de mediadora de lectores. Los fundamentos teóricos se basan, principalmente, en Coulon (1995a, 1995b), Vigotsky (1989, 1991, 2003), Graves y Graves (1995), Smith (1991), Jauss (2002), Iser (1996, 1999) y Amarilha (1996, 2001). Como resultados de este trabajo, se destacan el interés de la maestra, la manera en que ella se involucró con las historias leídas mediante procesos de identificación con algunos personajes y la relación que estableció entre los textos y su historia; esos procesos indican avances significativos en su vínculo con la lectura de literatura. La mediación ocupó un papel central en la consecución de aquellos avances. Vale destacar que la relación texto-vida fue establecida por la maestra con cierta ingenuidad, lo que le impidió vivenciar lo ficcional como una actividad lúdica. Se considera necesario un contacto más intenso y regular con textos de ficción, para que la docente pueda distanciarse de su vida cotidiana y adquirir la autonomía y la conciencia transformadora que le permitirán ir y volver de la realidad a la ficción, enriqueciéndose, sin confundirlas. Ese contacto no depende sólo de una actitud individual y personal de la maestra, sino del contexto institucional y social en el cual está inmersa. En ese sentido, la segunda etapa del trabajo de campo demostró que el pasaje de la formación lectora inicial a una acción pedagógica adecuada es complejo; los procesos no son lineales y, todavía, queda un largo camino por recorrer

Navegando nas ondas dos saberes do ser: uma conversa com a sexualidade à luz da corporeidade.

This study aimed to provide a continuing education towards raising teachers for reflection and effective sexual education within the school environment as a possible route of self-education and training of teachers of elementary school. More specifically aim to facilitate through the Continuing Education to discuss the knowledge of the body and knowledge of human sexuality, presenting them as core knowledge in the integral formation of individuals and promote discussion of a Human-centered education Teaching in a vocational training and human .In this sense, we dialogue with the human teaching preconized by Arroyo (2002, 2004) along with the humanization (hominization) of the individuals through education, under Freire´s perspective of the being more (2003) as well as his ideas, Pineau´s (2003) and Josso´s (2004) about the educational practice understanding as a way to build up the autonomy of the individuals who we intend to educate. We defend the inclusion of the body as an essential learning element according to the principles of corporeity presented by Assman (2001), whose comprehension is that every learning experience has a corporal inscription. Furthermore, the knowledge about human sexuality cannot be excluded from this process since the sexuality is inherent of individuals and is constructed and reconstructed during their existence. Our view of the world and of man is supported by the knowledge of the complexity (Morim, 2004) trying to surpass the mechanist view that sees them through the duality view, fragmenting them. For the discussion and construction of knowledge that search for the confluence of these knowledges about the being and the educational practice, aiming at the individual integral formation starting from the process of self-formation/self-knowledge, we´ve directed our research-action-formation having as compass the theoretical-methodological postulate of the research-action (Barbier, 2002; Morin, 2004; Thiollent, 2004) because it makes the participation of all the involved people in the process of resolution or surpassing of problem solving possible. We´ve used the continuing formation as a way of access for data collection, applying a questionnaire with open questions for the ones involved in the research. Based on the findings it´s been possible to infer that for the teaching formation it is necessary the inclusion of the Human sexuality and corporeity theme, so that the teacher can surpass the biological view of sexuality and also the expansion of the mechanist view of the body. To do so, we suggest that the teaching formation happens supported by the teaching capacitation and formation according to Maturana (2004), bringing teaching knowledges (Tardiff, 2002), which contribute effectively for the responsibility to educate people for life.

Hanseníase: a implicação da educação em saúde para o autocuidado

A hanseníase é um problema de saúde em nível mundial devido principalmente ao seu potencial incapacitante. A estratégia de combate à doença adotada pelo Ministério de Saúde é o diagnóstico e tratamento precoces, prevenção e tratamento de incapacidades físicas e vigilância dos contatos domiciliares. Tudo isso fundamentado na educação em saúde como sustentáculo para compreensão do processo de adoecimento, da doença em si, sua aceitação e, principalmente, das ações de autocuidado para prevenção de sequelas. Nesse contexto, questiona-se: Qual a implicação da assistência de enfermagem focada na educação em saúde para o autocuidado em portadores de hanseníase? O objetivo geral desse estudo é avaliar os conhecimentos adquiridos pelos portadores de hanseníase sobre a doença, o tratamento e autocuidado abordados durante a consulta de enfermagem. Trata-se de um estudo exploratório-descritivo com abordagem qualitativa, realizado no Hospital Universitário Onofre Lopes. Respeitou a resolução 466/12 do Conselho Nacional de Saúde e foi aprovado pelo comitê de ética sob nº 387.769 e CAAE 17468213.0.0000.5537. Envolveu 14 portadores de hanseníase em tratamento no ambulatório de dermatologia do HUOL. Os dados foram coletados no período de 23 de setembro a 04 de novembro de 2013 por meio de entrevista semi-estruturada; e analisados a partir da analise de conteúdo de Bardin. Os resultados e discussões são apresentados através de um artigo, o qual atende os objetivos propostos, denominado O autocuidado realizado por portadores de hanseníase . Esse objetivou identificar as ações de autocuidado de portadores de hanseníase em uma unidade de referência a partir de três eixos temáticos emersos dos discursos dos sujeitos: 1.as complicações/sequelas da hanseníase conhecidas pelos portadores da doença; 2. as ações de autocuidado adotadas pelos portadores de hanseníase; 3. as possíveis contribuições de um grupo de autocuidado para os portadores de hanseníase. Constou-se aparente superficialidade no conhecimento dos pacientes sobre as complicações da hanseníase, como também, das ações de autocuidado realizadas por eles. Verificou-se também a importância da assistência de enfermagem ao portador de hanseníase, tanto na atenção primária, quanto nos demais níveis de complexidade 11 da assistência. Considera-se que o enfermeiro é um potencial colaborador da educação em saúde como alicerce para o controle e eliminação da hanseníase

Busca heurística através de algoritmo genético e memético com construção de vocábulos para o problema de atribuição de localidades a anéis Sonet

Telecommunications play a key role in contemporary society. However, as new technologies are put into the market, it also grows the demanding for new products and services that depend on the offered infrastructure, making the problems of planning telecommunications networks, despite the advances in technology, increasingly larger and complex. However, many of these problems can be formulated as models of combinatorial optimization, and the use of heuristic algorithms can help solving these issues in the planning phase. In this project it was developed two pure metaheuristic implementations Genetic algorithm (GA) and Memetic Algorithm (MA) plus a third hybrid implementation Memetic Algorithm with Vocabulary Building (MA+VB) for a problem in telecommunications that is known in the literature as Problem SONET Ring Assignment Problem or SRAP. The SRAP arises during the planning stage of the physical network and it consists in the selection of connections between a number of locations (customers) in order to meet a series of restrictions on the lowest possible cost. This problem is NP-hard, so efficient exact algorithms (in polynomial complexity ) are not known and may, indeed, even exist

Heurísticas usando construção de vocabuilário aplicadas ao problema da atribuição de localidades a anéis em redes SONET/SDH

The SONET/SDH Ring Assignment Problem (PALAS) treats to group localities in form of some rings, being respected the traffic's limitations of the equipment. Each ring uses a DXC (Digital Cross Connect) to make the communication with the others, being the DXC the equipment most expensive of the net, minimizing the number total of rings, will minimize the total net cost, problem's objective . This topology in rings provides a bigger capacity of regeneration. The PALAS is a problem in Combinatorial Optimization of NP-hard Class. It can be solved through Heuristics and Metaheuristics. In this text, we use Taboo Search while we keep a set of elite solutions to be used in the formation of a part of the collection of vocabulary's parts that in turn will be used in the Vocabulary Building. The Vocabulary Building will be started case Taboo Search does not reach the best solution for the instance. Three approaches had been implemented: one that only uses vocabulary's parts deriving of Taboo Search, one that it only uses vocabulary's parts randomly generated and a last one that it uses half come of the elite and half randomly generated

Algoritmo evolutivo paralelo para o problema de atribuição de localidades a anéis em redes sonet/sdh

The telecommunications play a fundamental role in the contemporary society, having as one of its main roles to give people the possibility to connect them and integrate them into society in which they operate and, therewith, accelerate development through knowledge. But as new technologies are introduced on the market, increases the demand for new products and services that depend on the infrastructure offered, making the problems of planning of telecommunication networks become increasingly large and complex. Many of these problems, however, can be formulated as combinatorial optimization models, and the use of heuristic algorithms can help solve these issues in the planning phase. This paper proposes the development of a Parallel Evolutionary Algorithm to be applied to telecommunications problem known in the literature as SONET Ring Assignment Problem SRAP. This problem is the class NP-hard and arises during the physical planning of a telecommunication network and consists of determining the connections between locations (customers), satisfying a series of constrains of the lowest possible cost. Experimental results illustrate the effectiveness of the Evolutionary Algorithm parallel, over other methods, to obtain solutions that are either optimal or very close to it

Gestão ambiental: um estudo sobre a percepção do problema da desertificação no Estado do Rio Grande do Norte

The objective of this study was to investigate the environmental perception of: People with common-sense knowledge on the desertification process in RN. People with scientific knowledge on the desertification process in RN. Focal points in the combat at desertification of the RN and public ministery representant with actions in interinstitutional articulations promoter (and/or relative actions) at the desertification process in the RN. The research was carried in the city of Natal-RN and in two small cities of the Seridó region (RN): Caicó and Currais Novos. The research carried, is classified as exploratory and 22 people were interviewed. The research includes: The propension/intensity of the desertification in the RN and in the Seridó region; Evaluation of the knowledge of those interviewed, concerning the subject desertification ; Problems in order to combat desertification; Causes of desertification; The profile of the interviewed. The results of this present study indicate that the a desertification process is more agressive in the Seridó region than in the state of RN, being the two following: the absence of preocupation of the affected population with the process and the escarcity of governamental recurses, indicates how problems greather in the combat to the phenomen. Decreasing of produtivity in the agriculture and increasing of the migration to the urbans centers have been the main consequences of the process, that have at water scarcity, deforestation and extraction of argil (being this, regional factor), relevant variables in the influence to the surgiment of the desertification process of the RN

Um algoritmo híbrido para o problema de roteamento de veículos com frotas heterogêneas

This paper aims to propose a hybrid meta-heuristics for the Heterogeneous Fleet Vehicle Routing Problem (HVRP), which is a combinatorial optimization problem NP-hard, and is characterized by the use of a limited fleet consists of different vehicles with different capacities. The hybrid method developed makes use of a memetic algorithm associated with the component optimizer Vocabulary Building. The resulting hybrid meta-heuristic was implemented in the programming language C + + and computational experiments generated good results in relation to meta-heuristic applied in isolation, proving the efficiency of the proposed method.
