É preciso estar atento: um estudo da relação entre desenvolvimento da atenção e aprendizagem

Se discute en este estudio la relación entre o desarrollo de la atención y el aprendizaje de la lengua escrita realizada con los alumnos del 5º grado de la Enseñanza Primaria, compuesta de 25 alumnos, con la edad entre 9 e 13 años, de la Escola Municipal Professor Arnaldo Monteiro Natal/RN. Para el desarrollo de este proceso investigativo, utilizamos como aporte teórico el materialismo histórico-dialéctico, pues ese método posibilita el análisis de los fenómenos y, a través de esa lógica, se revelan los elementos que dieron sustentación a la mediación pedagógica y comprensión de los fenómenos con mayor eficacia. También fueron usados los estudios de Vigotski (1991), Rubinstein (1973), Ferreira (2003), Ibiapina (2007), y otros que convergen con ese posicionamiento. Se adoptó la pesquisa colaborativa que supone la construcción de un objeto del conocimiento entre investigador y profesor y también asocia al mismo tiempo actividades de producción del conocimiento y de desenvolvimiento profesional, proponiéndose una mediación entre comunidad de investigadores y comunidad de profesores. Utilizamos como elementos metodológicos el diagnóstico de la atención, el diagnóstico de la producción escrita del texto narrativo, siguiendo las etapas elaboradas por Infante (1998), los diarios reflexivos, el planeamiento y las sesiones reflexivas (con alumnos y con los pares). Para análisis del desarrollo de la atención, utilizamos las categorías definidas por Luria (1991): volumen de la atención, estabilidad de la atención, oscilación de la atención. El análisis de la producción textual tuve como parámetros las categorías de cohesión y coherencia (COSTA VAL, 1999). Para esto, se reflexionó con ellos sobre la importancia del desenvolvimiento de la atención para aprendizajes más efectivas. Propusimos situaciones de aprendizajes que posibiliten el desarrollo de la atención de esos alumnos y el dominio de la producción textual; y se analizaron las interrelaciones entre desenvolvimiento de la atención y la producción de textos narrativos. Los resultados presentados en los textos permiten afirmar que es notoria la relación entre la atención y el aprendizaje de la escritura. Vale resaltar que la reflexión no puede tener un fin en si mismo o entonces ser usada apenas para justificar una acción, mas debe tener como objetivo mejorar la enseñaza y tornar los profesores más conscientes y, por lo tanto, más capacitados para ejercer su profesión

O currículo escolar: uma análise na perspectiva da inclusão de alunos com deficiência intelectual

A mid the many transformations and advances that the contemporary society is going through, the right to education is a topic that does not end and becomes increasingly present, given the urgency of including students with disabilities in education. Given this new reality, schools are challenged to receive them with quality, and implement actions that promote favorable conditions for their development at school. Accordingly, it is fundamental the organizational restructuring of education to meet the specific needs of students. Thus, it is imperative that educational institutions defining the type of person who intend to form and the society proposing to build. These are aspects that precede any question, since the knowledge covered in the curriculum will contribute directly to the creation of human beings are involved there. Based on this theme, this assignment reports aspects of a survey of a local public school, located in Natal/RN, which deals with the analysis of the curriculum and its implementation in teaching practice in the classroom, before the inclusion of students with disabilities intellectual. Thus, to undertake a study of case with five professionals at school, involving documentary analysis and observation of the curriculum of the pedagogical practice of teachers in the classroom, as well as conducting an interview with all stakeholders. To this end, the data analyzed shows that, although the right of citizens with disabilities is guaranteed by constitutional law, the school, locus of this study, have not realized the extent of conquest. Does not recognize the fact of being in school and learn together with others is also a right of persons with disabilities. Thus, while your resume is to present a progressive vision, believed to be open, concerned with the selection and organization of content, with flexibility in defining the goals, with the search for diversification of the procedures adopted, as well as the planning activities teaching and learning based on the level of student learning, this is not effective in teaching practice, either through ignorance of the guidelines defined either by lack of knowledge about the proposal and an inclusive curriculum can provide answers to all educational students, including those with intellectual disability

Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

A aprendizagem na convivência:o estágio curricular em enfermagem

This is an analytic research of a qualitative nature whose purpose is to examine the learning process involving students of the Nursing Program of the Universidade Federal do Rio Grande do Norte UFRN who are attending the Supervised Clerkship in Nursing (SCN) in Family Health Strategy (FHS), based on learning through daily living. In order to do this, a historical overview of this academic activity in the teaching of nursing was presented, and the importance of FHS as the scene where professional health education takes place was discussed. For the empirical investigation, ten eighth-semester students involved in clerkship activities at family health units in the Western Sanitary District of Natal, Rio Grande do Norte, were interviewed. The theoretical approach relied, as epistemological presupposition, on the ideas of educator Humberto Maturana who showed that learning, both in nature and among human beings, takes place within dialogic living relationships wherein acceptance of the other, affectivity (love) and dialoguing are essential stimuli to learning. Students discourses gradually became part of the analytic categories that had been established beforehand. There has been verified that the students went through meaningful learning encouraged by all who shared the living environment, that is: nurse/instructor, teacher/supervisor, family health staff, and the community. Several feelings were involved in the process, such as joy, satisfaction, self-reliance, affectivity and, in the opposite direction, sadness, indignation, a feeling of impotence, and fear. The learning of interpersonal relationship was describe as the most relevant of the academic experiences and, therefore, thus emphasizing the relevance of affectivity to the learning process as Maturana points out. It is suggested that the teaching of nursing keep on giving priority to family health units as the Basic Care educational scene, with attention to the importance of placing the students in welcoming environments, in such a way as to encourage learning

Entre flores e espinhos: a atuação do técnico em enfermagem na estratégia saúde da família

It is about a study of an exploratory/descriptive type with a qualitative approach whose aim was to analyze the actuation of nursing technicians in Family Health Strategy (FHS), taking into consideration the defined attributions by the Ministry of Health (MH). Thus, it was sought to identify what activities they carry out, the difficulties encountered, what contributed to their professional performance, and what vision they have about FHS and about themselves in the context. Based on the assumption that the practice of Nursing Technician is not still geared to completeness and that the developed actions by this professional are predominantly individual and curative. We know that FHS proposes the work organization as a team, with territory definition, prioritization of promotion actions, protection and recovery of the individual/family/community health, choosing as a central point the establishment of entails between the professionals and the same ones. However, the team work pass through interdisciplinary, tying and competence, starting making the difference in the way of thinking and doing health. To the accomplishment of this study were interviewed twenty one Nursing Technicians of Family Health Units from Sanitário Oeste district in Natal-RN, using semistructured instrument. From the analysis, three empiric categories emerged: starting from the first, The reality of a dream: what FHS is for the Nursing Technician, we obtained two classifications: one inherent to the own conception they have about FHS, nominated The realization of a dream in the possible and another that corresponds to what they think about FHS, while project that doesn't take place fully, denominated of The beauty of a dream that doesn't take place. The second category was The FHS: a dream built in the daily of Nursing Technician treats of the day by day information of that professional; the activities they perform and how those are established. This created three other items, to know: The role of a Nursing Technician: a project that became routine; The pre-determined role of a Nursing Technician: the scale as factor of (non-)autonomy; and, Knowledge about the practice in FHS: challenges that are presented to the role of Nursing Technician. The third category, denominated of Charms and disenchantment in the beginning of a new practice, it is related to the facilities or difficulties in professional's actuation and how he sees himself in the context. From it emerged the "flowers" and the "thorns" found on the construction of a dream, which gave this study the title. The results indicate that, being considered the characteristics of researched professional category, it becomes fundamental the resizing of labor relations in FHS, being imperative that new glances is conducted, so that the way as those Nursing Technicians interacts with the families can become compatible, together with the team, as well as to return the attention for their possibilities and limits in face of the work process in FHS. Besides, it is necessary changes in the professional formation, so that it can guarantee the conceptual bases in the construction of new practices, seeking to answer to the model of current attention.

Conhecimento dos enfermeiros do Hospital Universitário Onofre Lopes sobre sistematização da assistência de Enfermagem

Nursing as a profession goes in search on quality of their care through new frameworks, trying to break postures of the health care system so fragmented in the care. To change professional practices, it is necessary to build their own knowledge grounded on Nursing Care System. The aim of this study was to analyze the influence of nurses' knowledge on care systematization in nursing in the University Hospital Natal-RN. It is an analytical descriptive study carried out at the Onofre Lopes University Hospital (HUOL), Natal-RN, 2010, the sample was composed of 40 active nurses working in hospitalization units of the hospital, the inclusion criteria were being in the monthly scale sector and agree to participate in the study. The non-participant observation and another interview were used for collecting data, statistical analysis was descriptive and inferential with reliability test, Pearson test, chi-square and Fischer, the variables that correlated were analyzed in a model Multiple logistic , calculating odds ratio. The results were: predominance of female professionals (90%), predominantly in the age range 39-46 years (37.5%), nurses who have the undergraduate degree at the Federal University of Rio Grande do Norte (80%), and who have expertise training as a minimal degree (62.5%). Among the surveyed, the knowledge showed significance with the graduation time (p = 0.018) and time working in HUOL (p = 0.036). The majority of the professionals surveyed do not know which organ is responsible for the SAE legislation (52.5%), aware of the steps needed to build the nursing diagnosis (92.5%), understand the characteristics of nursing planning (90% ). However the same professionals do not perform physical examination in patients (50.0%) did not classify the clinical findings (68.4%), and identify the problems encountered as a classification (13.2%). The planning of nursing care is carried out by verbal order of nurses (82.5%), 41% of the professionals assess only the intervention stage, in other words, the actions taken. Regarding the practical application of nursing records 53% of nurses do not realize records, 30.8% is incomplete, the other held notes (p = 0.003). The nurses know the nursing process (90% of appropriate responses), despite the actions defined by the theory are not applied in practice. Investigators believe the condition of the hospital teacher (22.5%) could positively affect the implementation of the SAE associated with the interest of professionals (20%). Of the respondents, 17.5% accept as truth the lack of facilities to assist the SAE implementation in the hospital. It was concluded that nurses know the theory that underlies the SAE and the nursing process, but do not develop the service know as well, there is need for action to boost the SAE implementation as practice of nurses in the hospital investigated

Estágio supervisionado em enfermagem: visão de preceptores

The present study aimed to analyze the vision of tutors from a university hospital about supervised internship in nursing. It is a descriptive nature research with qualitative approach, developed at the University Hospital Onofre Lopes (HUOL), located in Natal/RN. The population was composed of eleven assisting nurses engaged the precentorship of undergraduate course students in nursing, from the Federal University of Rio Grande do Norte (UFRN). For the empirical research, conducted in the period from September to November 2013, the semi-structured interview involving questions directed to the stage was used, as advocate the national curriculum guidelines, as regards this curricular component. With the consent of the institution where the study has been developed and approved by the Research Ethics Committee of UFRN, as n° 17800613.9.0000.5537, besides CAAE signing an informed consent by participants. The analysis of the information was held from the analysis of content, thematic mode. Thereby four categories were defined a priori, namely: the supervised internship in the vision of nurses; To be preceptor; The internship concerned: contributions and difficulties; Do the institutional actors communicate? The results indicate that in the view of the supervised internship preceptors is a sine qua non for the training of nurses, considering that it prepares for professional life. Besides being a moment conducive to the exercise of management and a greater rapprochement between theory and practice, stimulates the preceptor to upgrade to better exercise the function and also provides an exchange of knowledge between students and tutors, thus contributing to optimize the service. Nevertheless, the respondents indicate the existence of a distancing and little communication with the academic institution. In summary, it is realized that the nurses understand the importance of its function of tutors and supervised stage for vocational training. It is necessary, however, to reflect on the paths to be pinched in the confrontation of difficulties in this process, especially as regards the teaching/service relationship, which, while remaining at a distance, strengthens the existing dichotomy between theory and practice

Análise de desempenho de vendas em telecomunicações utilizando técnicas de mineração de dados

Nowadays, telecommunications is one of the most dynamic and strategic areas in the world. Organizations are always seeking to find new management practices within an ever increasing competitive environment where resources are getting scarce. In this scenario, data obtained from business and corporate processes have even greater importance, although this data is not yet adequately explored. Knowledge Discovery in Databases (KDD) appears then, as an option to allow the study of complex problems in different areas of management. This work proposes both a systematization of KDD activities using concepts from different methodologies, such as CRISP-DM, SEMMA and FAYYAD approaches and a study concerning the viability of multivariate regression analysis models to explain corporative telecommunications sales using performance indicators. Thus, statistical methods were outlined to analyze the effects of such indicators on the behavior of business productivity. According to business and standard statistical analysis, equations were defined and fit to their respective determination coefficients. Tests of hypotheses were also conducted on parameters with the purpose of validating the regression models. The results show that there is a relationship between these development indicators and the amount of sales

Gestão ambiental na saúde pública: um estudo sobre a percepção ambiental de gerenciamento de resíduos sólidos de serviços de saúde, dos servidores do Hospital Universitário Onofre Lopes do Rio Grande do Norte

This research has aimed at studying the perception of University Hospital Onofre Lopes (HUOL) s workers on the environmental management plan of RSSS. They have been interviewed 250 workers: doctors, nurses, nursing assistants, and cleaners. It was used an exploratory and descriptive research of the type Survey, which aims at obtaining of data or information on characteristics, actions or opinions of any group of people. The questions of the questionnaire were of the kind objective", formulated in a model "scale", analyzed in according to the positioning of the interviewee. The wastes of health service have high potential for environmental impact in the activities from HUOL. Actions or environmental protective policy can improve the image of HUOL. They have been detected divergences on the rigor in application of law of ANVISA. The HUOL s workers unaware of the law of ANVISA and they have little or no knowledge about the practices of environmental control, public health and, they do not know the Environmental Management System ISO 14001. They have divergent views on the degree of importance of ISO 14001. There is not a Waste Management Plan for Health Service and / or is not disclosed for most of HUOL workers. It has not carried out audits or defined the goals and objectives. Besides, it has not been identified legal requirements, and there has not been communication about the service is performed or has been made a critical analysis and no control of documents the environmental management plan. The HUOL have not had a committee of environmental management. The direction of HUOL has not been organized courses, training and recycling of waste on environmental control of the health service. On a scale from 01 to 05, the level of aware level concerning to the waste management from health services of the workers, so is at the threshold between 01 and 02. For the reversal of this situation, the first and urgent step is the creation and institutionalization the environmental management committee of the University Hospital Onofre Lopes

Identificação fuzzy-multimodelos para sistemas não lineares

This paper presents a new multi-model technique of dentification in ANFIS for nonlinear systems. In this technique, the structure used is of the fuzzy Takagi-Sugeno of which the consequences are local linear models that represent the system of different points of operation and the precursors are membership functions whose adjustments are realized by the learning phase of the neuro-fuzzy ANFIS technique. The models that represent the system at different points of the operation can be found with linearization techniques like, for example, the Least Squares method that is robust against sounds and of simple application. The fuzzy system is responsible for informing the proportion of each model that should be utilized, using the membership functions. The membership functions can be adjusted by ANFIS with the use of neural network algorithms, like the back propagation error type, in such a way that the models found for each area are correctly interpolated and define an action of each model for possible entries into the system. In multi-models, the definition of action of models is known as metrics and, since this paper is based on ANFIS, it shall be denominated in ANFIS metrics. This way, ANFIS metrics is utilized to interpolate various models, composing a system to be identified. Differing from the traditional ANFIS, the created technique necessarily represents the system in various well defined regions by unaltered models whose pondered activation as per the membership functions. The selection of regions for the application of the Least Squares method is realized manually from the graphic analysis of the system behavior or from the physical characteristics of the plant. This selection serves as a base to initiate the linear model defining technique and generating the initial configuration of the membership functions. The experiments are conducted in a teaching tank, with multiple sections, designed and created to show the characteristics of the technique. The results from this tank illustrate the performance reached by the technique in task of identifying, utilizing configurations of ANFIS, comparing the developed technique with various models of simple metrics and comparing with the NNARX technique, also adapted to identification

Projeto de um sistema emulador de escoamentos e vaso de separação primária

The purpose of this study was to develop a pilot plant which the main goal is to emulate a flow peak pressure in a separation vessel. Effect similar that is caused by the production in a slug flow in production wells equipped with the artificial lift method plunger lift. The motivation for its development was the need to test in a plant on a smaller scale, a new technique developed to estimate the gas flow in production wells equipped with plunger lift. To develop it, studies about multiphase flow effects, operation methods of artificial lift in plunger lift wells, industrial instrumentation elements, control valves, vessel sizing separators and measurement systems were done. The methodology used was the definition of process flowcharts, its parameters and how the effects needed would be generated for the success of the experiments. Therefore, control valves, the design and construction of vessels and the acquisition of other equipment used were defined. One of the vessels works as a tank of compressed air that is connected to the separation vessel and generates pulses of gas controlled by a on/off valve. With the emulator system ready, several control experiments were made, being the control of peak flow pressure generation and the flow meter the main experiments, this way, it was confirmed the efficiency of the plant usage in the problem that motivated it. It was concluded that the system is capable of generate effects of flow with peak pressure in a primary separation vessel. Studies such as the estimation of gas flow at the exit of the vessel and several academic studies can be done and tested on a smaller scale and then applied in real plants, avoiding waste of time and money.

Maximização da penetração da geração distribuída através do algoritmo de otimização nuvem de partículas

This work develops a methodology for defining the maximum active power being injected into predefined nodes in the studied distribution networks, considering the possibility of multiple accesses of generating units. The definition of these maximum values is obtained from an optimization study, in which further losses should not exceed those of the base case, i.e., without the presence of distributed generation. The restrictions on the loading of the branches and voltages of the system are respected. To face the problem it is proposed an algorithm, which is based on the numerical method called particle swarm optimization, applied to the study of AC conventional load flow and optimal load flow for maximizing the penetration of distributed generation. Alternatively, the Newton-Raphson method was incorporated to resolution of the load flow. The computer program is performed with the SCILAB software. The proposed algorithm is tested with the data from the IEEE network with 14 nodes and from another network, this one from the Rio Grande do Norte State, at a high voltage (69 kV), with 25 nodes. The algorithm defines allowed values of nominal active power of distributed generation, in percentage terms relative to the demand of the network, from reference values

Localização de um robô móvel usando odometria e marcos naturais

Several methods of mobile robot navigation request the mensuration of robot position and orientation in its workspace. In the wheeled mobile robot case, techniques based on odometry allow to determine the robot localization by the integration of incremental displacements of its wheels. However, this technique is subject to errors that accumulate with the distance traveled by the robot, making unfeasible its exclusive use. Other methods are based on the detection of natural or artificial landmarks present in the environment and whose location is known. This technique doesnt generate cumulative errors, but it can request a larger processing time than the methods based on odometry. Thus, many methods make use of both techniques, in such a way that the odometry errors are periodically corrected through mensurations obtained from landmarks. Accordding to this approach, this work proposes a hybrid localization system for wheeled mobile robots in indoor environments based on odometry and natural landmarks. The landmarks are straight lines de.ned by the junctions in environments floor, forming a bi-dimensional grid. The landmark detection from digital images is perfomed through the Hough transform. Heuristics are associated with that transform to allow its application in real time. To reduce the search time of landmarks, we propose to map odometry errors in an area of the captured image that possesses high probability of containing the sought mark

Controle dinâmico de robôs móveis com acionamento diferencial

This work addresses the dynamic control problem of two-wheeled differentially driven non-holonomic mobile robot. Strategies for robot positioning control and robot orientating control are presented. Such strategies just require information about the robot con¯guration (x, y and teta), which can be collected by an absolute positioning system. The strategies development is related to a change on the controlled variables for such systems, from x, y and teta to s (denoting the robot linear displacement) and teta, and makes use of the polar coordinates representation for the robot kinematic model. Thus, it is possible to obtain a linear representation for the mobile robot dynamic model and to develop such strategies. It is also presented that such strategies allow the use of linear controllers to solve the control problem. It is shown that there is flexibility to choice the linear controller (P, PI, PID, Model Matching techniques, others) to be implemented. This work presents an introduction to mobile robotics and their characteristics followed by the control strategies development and controllers design. Finally, simulated and experimental results are presented and commented

Uma proposta de um controlador adaptativo por posicionamento de pólos e estrutura variável

There are two main approaches for using in adaptive controllers. One is the so-called model reference adaptive control (MRAC), and the other is the so-called adaptive pole placement control (APPC). In MRAC, a reference model is chosen to generate the desired trajectory that the plant output has to follow, and it can require cancellation of the plant zeros. Due to its flexibility in choosing the controller design methodology (state feedback, compensator design, linear quadratic, etc.) and the adaptive law (least squares, gradient, etc.), the APPC is the most general type of adaptive control. Traditionally, it has been developed in an indirect approach and, as an advantage, it may be applied to non-minimum phase plants, because do not involve plant zero-pole cancellations. The integration to variable structure systems allows to aggregate fast transient and robustness to parametric uncertainties and disturbances, as well. In this work, a variable structure adaptive pole placement control (VS-APPC) is proposed. Therefore, new switching laws are proposed, instead of using the traditional integral adaptive laws. Additionally, simulation results for an unstable first order system and simulation and practical results for a three-phase induction motor are shown
