In recent years, in Brazil, researches in the area of education have been focused on the study of the necessities of formation, by the practice of necessity analysis, to subside the continued teacher formation programs. This research on the necessity of the formation of literacy teachers in the initial years of primary education originated in our discussions in academia, regarding the issues of retention and evasion related to basic literacy teaching in Brazilian public schools. We defined as a goal: to know the necessities of the formation of literacy teachers from Odila Leite Municipal Elementary School, Natal/RN, which focuses on the literacy teaching on that level of education and in Adult and Youth Education. The object is the necessities in these teachers formation. The thesis is that the literacy teacher reveals/constructs formation necessities when speaking of her practice, when exerting said practice or even when producing teaching materials which subside that practice; in other words, when making the theoretical/practical relation related to literacy teaching. The approach is qualitative, according to which the natural environment is the source for data collection; the focus of interest is the process of knowledge construction, and fundamental importance is given to the meanings constructed by the subjects. We comprehended that necessity is a socially constructed subjective phenomenon, and that necessity analysis allows the revelation of formation objectives. We used the case study as a methodological strategy which permits: studying a well-defined entity, [ ] as well as an academic institution; the global comprehension of the phenomenon of interest; discovering what is most essential and characteristic in the object. We counted with 17 teachers, 3 of which had their teaching practices observed. We observed the school routine, analyzed the main class documents and plans and interviewed the 17 teachers. We triangulated the data obtained by the routine observation, the observation of the three teachers practices and by the document analysis, next, we triangulated this data with the data from the analyzing the interviews with the 17 teachers. Such procedures reveal formation necessities in those teachers , such as: studying child cognitive development; reviewing the concepts of literacy teaching; reviewing fundaments of written language psychogenesis; reflecting on reading practices and literature; reflecting on the practice of daily planning; reflecting on the school s material conditions and the family/school relation. We concluded that researches of this nature contribute to the orientation of teacher formation programs

This research aims to analyze the FIC Course of Assistant Technician in Service Management and Quality, integrated to elementary education / EJA form developed by IFRN MO Campus between 2011 and 2013 in the form of a PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL. We seek to understand the adhesion between the national guidelines postulated for the Program, established in PPC and mediations with the process conceived in the run of the course. Guiding by the socio-critical approach and the dialogical paradigm, the theoretical-epistemological mark is especially buoyed by the theoretical contributions of Ciavatta (2005) , Rock (2011) , Haddad and Di Pierro (2000), Freire (2005), Marx (1982), Ramos (2005), Frigotto; Ciavatta; Ramos (2005), Moura (2012), and also on education in prisons by Onofre (2007, 2011), Bueno (2007), Julião (2011) and Foucault (2001). We assume that an action that enables professional qualification as FIC courses articulated to the EJA in the context of education in prisons have conceptual, methodological, political and pedagogical implications for it focuses challenges, weaknesses and opportunities on the same area of education., We have developed four techniques of data collection based on procedures and tools of qualitative research, such as document analysis, a student survey, the conduction of focus groups with teachers and administrators of the course and on-site observation. Mediated by the investigated context, results showed that the consolidation of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL goes beyond the intentions officially declared. It is inferred that after seven years of its creation, even though it keeps some potential, this program is not being satisfactorily developed and it shows weaknesses national and locally, it is set at low capillarity, it has a limited scope, and dissolved essential public commitments to the course development. The effectiveness of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL as part of an emancipatory inclusion social policy, according to official statement, entails approximating the legal logic with social logic, so as not only to propagate discourses and enforce worship to specific and successful experiences that reach only a minority, but to provide actual and necessary conditions to promote the breadth and social quality of the offered deals in this program format

Care has always been present in the history of humanity and in contemporary nursing it is considered to be a fundamental characteristic. In the Intensive Care Unit (ICU), care occurs within an environment that is known for its stressful factors, technological equipment, social isolation and discomfort. Whilst the reality of nursing practice in ICU demonstrates the lack of planned and systematized care, there is an indication that the professionals working in this setting utilize some type of knowledge. Based on that premise, in this study we aim to identify the knowledge that the nurses use in providing care in the ICU. We believe that the identification and characterization of this knowledge, and how it presents itself in practice, requires a reflective analysis process. Therefore, we utilized a qualitative perspective and Kim´s (1999) investigative methodology of reflective inquiry that is based on the precepts of Action Science proposed by Argyris et al. (1985). The study was conducted with 8 intensive care nurses of a public hospital. Data were collected by means of non-participative observation of the nursing care actions and a semi-structured interview conducted within the reflective mode that focused on the nurses practice in the ICU. The results enabled us no only to detect that the nurses utilized knowledge and patterns of knowledge acquired or constructed, but to identify them as: scientific, philosophic, religious, empirical, personal, ethical, and esthetic knowledge. The predominance of the scientific knowledge in the care process suggests that these nurses hold an acquired scientific substance that they utilize to provide specialized care directed toward critical treatment. The conception of this reality surpasses the theoretical limits, the techniques, and the known facts, and denotes the need for a reflective process in action to aide in the comprehension of the knowledge involved in the construction of excellent care

Alma-Ata declaration bring the Primary Attention to the Health (PAH) as first level of health attention for individuals, family and community, which considers infant group as priority. Several initiatives that gave bases to integral attention to the children health formalized in the principles of Unique Health System. Family Health Strategy (FHS) comes to strengthen this attention, instituting new ways of work organization and professional practices that gave impact in their quality indicators. One of them is children mortality, showing decline in their values. Though, studies indicates persistence of avoidable infant deaths. In Natal RN, this reality is also perceptible leading to inquietudes, mainly at the space of services production, it means, which motivated the accomplishment of the present study intending to analyse the way that the organizational and structural processes as long as the professional practices in FHS interfered in the quality of children s health attention who died by avoidable death in the year of 2007 in municipal district of Natal-RN. It treats, therefore, to an exploratory and descriptive survey of cases study type, thar had as primary sources the oficial documents of MH, the family prontuary, pregnant card, child card and testimony obt ined from instrument of research elaborated based in investigation form of infant death by MH, applied to 10 mothers of children who had avoidable death. In analysis it was appealed silmultaneous triangulation of methods and sources, allowing a bigger aproximation from obtained informations. To elucidate the cases, the aspects studied were analyzed to the light of explicative model of Social Determinants of Health. Among individual and family aspects were highlighted the related to age, schooling, family habits and customs and mother s economic condition, besides of pregnancy age, newborn weight and associated diseases, which don t differ from literature about the theme. Reffering to the factors organizational and structural processes and professionals practice, highlihgted, the treatment given by the professionals, the territorialization and adscription of areas, the difficulty of having access to the services or sleepers and the reference and counterreference. But also, the ausence or few greet, the lack of communication, few assiduity and ponctuality by professionals in service, among others. In a general way mothers considers the attendance received in the hospital good and very good , opnions that in the Basic Attention weren t so favorable, in spite of many of predictible actions in this level have been performed in the studied cases. It is observed, therefore, that the social determinants of health has a strong influence in ocurrence of infant deaths, what implicates in a large actuation by Infant Mortality Committee from municipal district. This way, it becomes fundamental the reflection and evaluation about the effectiveness and execution by the processes of vigilance to health in FHUs; the rethink about the social determinants of health in a wide and articulate way to the services quality, to permanent education, to management in service, to the given attention and to the way how it is installed the popular participation and social control. To the professionals it is presented the great challenge to review their daily practice, their values, behaviors and commitment, which ones must be guided by logical of sharing, work in team, humanescence and alterity, not only by the accomplishment of a professional duty

Nowadays, where the market competition requires products with better quality and a constant search for cost savings and a better use of raw materials, the research for more efficient control strategies becomes vital. In Natural Gas Processin Units (NGPUs), as in the most chemical processes, the quality control is accomplished through their products composition. However, the chemical composition analysis has a long measurement time, even when performed by instruments such as gas chromatographs. This fact hinders the development of control strategies to provide a better process yield. The natural gas processing is one of the most important activities in the petroleum industry. The main economic product of a NGPU is the liquefied petroleum gas (LPG). The LPG is ideally composed by propane and butane, however, in practice, its composition has some contaminants, such as ethane and pentane. In this work is proposed an inferential system using neural networks to estimate the ethane and pentane mole fractions in LPG and the propane mole fraction in residual gas. The goal is to provide the values of these estimated variables in every minute using a single multilayer neural network, making it possibly to apply inferential control techniques in order to monitor the LPG quality and to reduce the propane loss in the process. To develop this work a NGPU was simulated in HYSYS R software, composed by two distillation collumns: deethanizer and debutanizer. The inference is performed through the process variables of the PID controllers present in the instrumentation of these columns. To reduce the complexity of the inferential neural network is used the statistical technique of principal component analysis to decrease the number of network inputs, thus forming a hybrid inferential system. It is also proposed in this work a simple strategy to correct the inferential system in real-time, based on measurements of the chromatographs which may exist in process under study

A irrigação é prática fundamental para o cultivo de crisântemo, porém seu manejo adequado tem sido negligenciado pelos produtores, resultando em prejuízos no crescimento vegetal e conseqüentes decréscimos na produtividade e na qualidade do produto final. Para melhorar a representatividade dos dados obtidos, o experimento foi desenvolvido na propriedade de um produtor tradicional, no Distrito de Holambra II, município de Paranapanema-SP (23º4'S e 49º00'W). O objetivo principal do trabalho foi identificar a tensão de água no substrato (potencial matricial) que resultasse em melhor crescimento e desenvolvimento do crisântemo em vaso, cultivar Puritan. Os tratamentos foram definidos por seis níveis de tensão de água no substrato: -2, -3, -4,- 6,-10 e -30 kPa. Conclui-se, que a melhor qualidade do crisântemo em vaso foi obtida nos potenciais de água no substrato de -2, -6 e -10 kPa e que a tensão de -30 kPa, embora tenha levado à redução na qualidade comercial do crisântemo, resultou em maior durabilidade pós- colheita.

A disponibilidade de informações relativas à oferta, preços e sazonalidade do abacaxi é um fator de interesse tanto para produtores quanto para atacadistas, pois podem contribuir para melhor planejamento da época de colheita e comercialização. Dessa maneira, o presente trabalho buscou conhecer a sazonalidade do preço e da quantidade do abacaxi comercializado na CEAGESP - SP, no período de setembro de 2005 a março de 2006. Foram obtidos através de entrevistas aos atacadistas, dados referentes à origem de cada cultivar em estudo, o preço pago ao produtor, o preço de venda praticado pelos atacadistas e a quantidade de frutos recebida no dia. Com o objetivo de compreender o processo de comercialização das cultivares de abacaxi 'Smooth Cayenne' e 'Pérola', foram aplicados questionários aos vendedores de três empresas atacadistas. Através das informações obtidas, sugere-se aos produtores de abacaxi 'Smooth Cayenne' o escalonamento da produção no período de novembro a fevereiro, preferencialmente de maneira associativista. Os três atacadistas de abacaxi entrevistados vislumbram uma estabilidade na quantidade comercializada de abacaxi na CEAGESP, com previsão de crescimento para a cultivar 'Pérola' e redução para a cultivar 'Smooth Cayenne'. No período de 12 de setembro de 2005 a 20 de março de 2006, observou-se uma estabilidade de preços pagos ao produtor para ambas as cultivares, com elevação de preços entre os dias 23 de janeiro a 06 de março de 2006 para a cultivar 'Pérola' e entre os dias 06 de fevereiro a 06 de março de 2006 para a cultivar 'Smooth Cayenne'. Os atacadistas consideram a cultivar 'Smooth Cayenne' mais valorizada nos meses de novembro a janeiro e a cultivar 'Pérola' de março a junho e de novembro a dezembro. Pelo cenário de estabilização do mercado de abacaxi, torna-se fundamental a garantia de sabor monitorada pelas associações de produtores em parceria com o Centro de Qualidade em Horticultura (CQH - CEAGESP) e atacadistas, com destaque para a cultivar 'Smooth Cayenne'.

The present work consists in the analysis of tribologycal properties of basic and multifunctional knitted fabrics. This knowledge has fundamental importance for the textile industry since it can quantify, in an objective way, the tactil. The fabrics used were characterized by friction and mechanical tests for determining the viscoelastic region, wear resistance and friction coefficient of the fabrics used. The stress-strain curve was obtained by the method Kawabata, KES-FB1. Wear tests performed with the aid of equipment Martindale. The measurement of friction coefficient, two methods were used and analyzed comparatively. The first was a method already established worldwide known as KES-FB4 and the second was an innovative method called FRICTORQ, developed by the University of Minho. These two methods were compared taking into account the relative motion between the tribologycal pairs are different from each method. While the first motion is translational, the second is rotational. It was formal that the knitted had a multifunctional fabrics tribologycal performance which was better than the basic knitted fabrics, as the viscoelastic region, was laager highlighting a multifunctional structure, with greater wear resistance mainly on the back side of the knitted fabrics and lower friction coefficient. Performing a comparative analysis between two methods used to measure the friction coefficient, it was formal that both methods were consistent in terms of results. In operational terms, the FRICTORQ showed ease of operation and increased reproducibility of results

The oil industry`s need to produce with maximum efficiency, not to mention the safety and the environment aspects, encourages the optimization of processes. It makes them look for a level of excellence in acquisition of equipment, ensuring the quality without prejudice security of facilities and peoples. Knowing the reliability of equipment and that this stands for a system is fundamental to the production strategy to seeks the maximum return on investment. The reliability analysis techniques have been increasingly applied in the industry as strategy for predicting failures likelihood ensuring the integrity of processes. Some reliability theories underlie the decisions to use stochastic calculations to estimate equipment failure. This dissertation proposes two techniques associating qualitative (through expertise opinion) and quantitative data (European North Sea oil companies fault database, Ored) applied on centrifugal pump to water injection system for secondary oil recovery on two scenarios. The data were processed in reliability commercial software. As a result of hybridization, it was possible to determine the pump life cycle and what impact on production if it fails. The technique guides the best maintenance policy - important tool for strategic decisions on asset management.

Sludge of Wastewater Treatment Plants (WTPs) disposal is a problem for any municipality, for this reason the amount of sludge production is now a key issue in selecting treatment methods. It is necessary to investigate new applications for this waste type, due to the restrictions imposed by the environmental organs. The raw materials used in the Red Ceramic, are generally very heterogeneous, for this reason, such materials can tolerate the presence of different types of wastes. In Rio Grande do Norte, the roof tiles production corresponds to 60,61% from the total of ceramic units produced. Due to the importance of the ceramic industry of roof tiles for the state, allied to the environmental problem of the sludge disposal, this work had for objective to verify the possibility of the incorporation of sewage sludge in ceramic body used for production of roof tiles. In the research, sludge originating from drying beds of WTP of the Central Campus from UFRN and clays originating from a ceramic industry from Goianinha/RN were used. The raw materials were characterized by techniques of: analysis of particles distribution by diffraction to laser; real density; consistence limits; chemical analysis by X-ray fluorescence; mineralogical analysis by X-ray diffraction; organic matter; and solids content. Five batches of roof tiles were manufactured in the approximate dosages of 2%, 4%, 6%, 8% and 10%. To evaluate the properties of each final product, tests of water absorption, impermeability, bending strength, leachability and solubility were accomplished. The roof tiles manufactured with sludge presented characteristics similar to the roof tiles without sludge in relation to the environmental risk. The results showed that it is possible to use approximately up to 4% of sludge in ceramic bodies for production of roof tiles. However, it is observed that the high amount of organic matter (71%) present in the sludge is shown as factor that limits the sludge incorporation in ceramic bodies, worsening the quality of the roof tiles. It is necessary the use of mixtures of different raw materials under point of view of the granulometry and of the other chemical and mineralogical properties for the obtaining of a satisfactory mass to the production of ceramic roof tiles

Es extensa, de parte de los docentes, la discusión sobre la articulación de actividades y estrategias de enseñanza que vengan a proporcionar una participación más activa del alumnado. Sin embargo tal tarea constituye un desafío para muchos profesores ya que, muchas veces, la formación inicial no siempre los prepara para esta perspectiva. Nosotros entendemos que es necesario desarrollar en los maestros una autonomía crítica, tomando la escuela como espacio formativo. El objetivo de este trabajo fue él de incentivar un espacio de discusión y reflexión para profesores en ejercicio de los 4° y 5° años de la Enseñanza Fundamental I. Ese espacio que era orientado para que ellos estudiasen y articulasen, entre otras cosas, el conocimiento disciplinar de Ciencias y la organización y sistematización de actividades de enseñanza que lleven a una participación más activa de los estudiantes. La investigación se realizó en una escuela privada de Natal/RN, que atiende a estudiantes desde la educación infantil hasta la enseñanza secundaria. Se desarrolló en cuatro fases: la 1ª, de familiarización, cuyo objeto de estudio se dio a través de la observación del salón de clase y del análisis de la planificación anual: la 2ª, de identificación de las dificultades de los maestros, teniendo como instrumentos encuestas con preguntas abiertas y elaboración de textos. La 3ª, en la perspectiva de proporcionar una intervención, se usó como instrumentos de investigación, el diario de clase y otras actividades como talleres, cursos y la elaboración de material didáctico. En la 4ª fase, para reconocer los posibles cambios en la práctica docente, ocurrieron nuevas observaciones en el salón de clase, el análisis de las planificaciones. Los datos obtenidos fueron organizados en tablas y clasificados. Los resultados señalan cambios en la práctica de esos profesionales, la introducción de la disciplina de Ciencias en el espacio formativo y el material didáctico elaborado ha sido un subsidio importante para ayudarlos en las clases
