O processo de cuidar em Unidade de Terapia Intensiva

The environment of Intensive Care Unit (ICU) is commonly referred to as a place where caring is inextricably linked to high technology. The care in ICU often changes the patient into a taxpayer being left apart from its complexity and sometimes seen through a reductionist perspective. Thus, studies circa the care process are needed oriented from a historical ransom, raising the prospect of a more centralized human care. Hence, this study aimed to analyze the care process in a nursing intensive care unit from the perspective of the professional, family and patients. The study is characterized from a qualitative, descriptive and exploratory methodological approach. The actors were participating nursing professionals, patients and family members of an intensive care unit of Mossoró / RN. Data were collected in the period of May-June 2011, through interviews and observation of activities performed by nursing professionals, and their records in the chart. Data analysis was divided into topics and subtopics representing the phases and shapes that formed the collection. The analysis and discussion of the interviews were based on Bardin's proposal, when we created categories from a process of sorting and grouping criteria adequately defined. The observation of nursing records intended to observe the emphasis which is described in those notes as well as their consistency with practice of FCN and resolution 358/2009. The analysis showed that the nursing staff also performs work focused on mechanized activities and technical-bureaucratic institution that seem to override the needs of patients. In an overview, the care provided by professionals occurs either fragmented or insipient, however there is a service that involves other aspects beyond technical-curative practice, considering that major attention is given to the family and patient, focused on the concern of Nursing guiding their actions in not only the performance of procedures. However, the process of humanizing not always ends with an engagement between professional and patient, which mischaracterizes the true meaning of human care. The records also showed a tendency to focus on caring in a positivist line, where, in most cases, the factors of the disease and the obligation to meet the productivity have overshadowed other relevant aspects to a holistic understanding of caring. Regarding FCN Resolution No. 358/2009, which guides a systematization of nursing care, it is confirmed a technical view, a fragmented and superficial view of the patient, as well as a weakness of care, caused by ignorance and unpreparedness of the entire team. The perspective of caring demonstrates a reality with dialectic between what is proposed in a humane nursing and what happens in this performance space. Besides, it was shown a daily full of important considerations that arise in professional practice, in their views and also those people who were participants in the process

A Relação professor-aluno e a afirmação do discente como sujeito do processo projetual: um estudo exploratório sobre a produção do trabalho final de graduação em arquitetura e urbanismo na UFC e na UFRN

This work deals with teacher-student relationship (TSR), held in a very special moment: the semester of graduation of architecture and urbanism, where students prepare the final work called Graduation Final Work (GFW). That is the last stage to obtain the title of architect and urban planner in Brazil. The text discusses this problem in several ways, emphasing the relationship between graduated student and his/her mentors into the consolidation process of the student as an actor of the planning process, here defined as "autonomy". The work is focused on understanding the TSR in order to elucidate its importance for improvement of teaching bases on development of the GFW, more than the relation between curriculum and institution. Related with the exploratory characteristic of this master thesis, methodologically, the field work happened through: (i) observation of mentorship guidance, (ii) interviews, and (iii) application of questionnaires to teachers and students. Participated 10 pairs of student and mentors of two federal university of Northeast: 05 pairs of the Federal University of Ceará (UFC) and 05 pairs of the Federal University of Rio Grande do Norte (UFRN). The results presented the development of the GFW as a difficult process / fearful for students, highlighting the main problem situations: the difficulty in choosing the theme, the super-sizing of the process, students' insecurities, and parental relationship with the supervisor process. Summing up, the work indicates that the students has a limited autonomy on the GFW process, which calls for a revision in order to promote the consolidation of the student autonomy, which must be observed for some positions recognition of the role of each actor in the process of orientation

Análise de métodos de predição de conforto térmico de habitação em clima quente-úmido com condicionamento passivo

The assessment of building thermal performance is often carried out using HVAC energy consumption data, when available, or thermal comfort variables measurements, for free-running buildings. Both types of data can be determined by monitoring or computer simulation. The assessment based on thermal comfort variables is the most complex because it depends on the determination of the thermal comfort zone. For these reasons, this master thesis explores methods of building thermal performance assessment using variables of thermal comfort simulated by DesignBuilder software. The main objective is to contribute to the development of methods to support architectural decisions during the design process, and energy and sustainable rating systems. The research method consists on selecting thermal comfort methods, modeling them in electronic sheets with output charts developed to optimize the analyses, which are used to assess the simulation results of low cost house configurations. The house models consist in a base case, which are already built, and changes in thermal transmittance, absorptance, and shading. The simulation results are assessed using each thermal comfort method, to identify the sensitivity of them. The final results show the limitations of the methods, the importance of a method that considers thermal radiance and wind speed, and the contribution of the chart proposed

Síntese e caracterização de TaC e óxido misto de tântalo e cobre nanoestruturados a partir do precursor oxálico de tântalo através de reações gás-sólido e sólido-sólido a baixa temperatura

The research and development of nanostructured materials have been growing significantly in the last years. These materials have properties that were significantly modified as compared to conventional materials due to the extremely small dimensions of the crystallites. The tantalum carbide (TaC) is an extremely hard material that has high hardness, high melting point, high chemical stability, good resistance to chemical attack and thermal shock and excellent resistance to oxidation and corrosion. The Compounds of Tantalum impregnated with copper also have excellent dielectric and magnetic properties. Therefore, this study aimed to obtain TaC and mixed tantalum oxide and nanostructured copper from the precursor of tris (oxalate) hydrate ammonium oxitantalato, through gas-solid reaction and solid-solid respectively at low temperature (1000 ° C) and short reaction time. The materials obtained were characterized by X-ray diffraction (XRD), Rietveld refinement, Scanning Electron Microscopy (SEM), Spectroscopy X-Ray Fluorescence (XRF), infrared spectroscopy (IR), thermogravimetric (TG), thermal analysis (DTA) and BET. Through the XRD analyses and the Reitiveld refinement of the TaC with S = 1.1584, we observed the formation of pure tantalum carbide and cubic structure with average crystallite size on the order of 12.5 nanometers. From the synthesis made of mixed oxide of tantalum and copper were formed two distinct phases: CuTa10O26 and Ta2O5, although the latter has been formed in lesser amounts

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

Design gráfico da pluma de contaminação por compostos orgânicos voláteiss utilizando software CAD na investigação de passivo ambiental em um posto revendedor de combustíveis em Natal/RN

Among the potentially polluting economic activities that compromise the quality of groundwater are the gas stations. The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel

Sobre a constituição do sujeito: uma análise comparativa entre a psicologia sócio-sociologia do conhecimento de berger e luckmann

This study investigated how the process of the constitution of the subject is interpreted in the formulations of the founders of socio-historical psychology (Lev S. Vigotski, Alexei N. Leontiev and Alexander R. Luria) and in the sociology of knowledge of Peter Berger and Thomas Luckmann. These two theoretical perspectives, despite having different philosophical formulations as ontological and epistemological intentions (socio-historical psychology, historical dialectical materialism; the sociology of Berger and Luckmann and phenomenology) arrive, however, at the same basic conclusion about the social nature of the subject. The objective of the study, therefore, was that of identifying the differences and convergences between the two perspectives and then, try to determine the possibility of a theoretical synthesis between them in relation to the constitution of the subject. At the same time, we intended to analyse the implications of this possible synthesis in order to comprehend the manner in which the ideology functions in human societies as thought by Louis Althusser and Alípio de Sousa Filho. We arrived at the conclusion that, despite being incompatible from the ontological and epistemological points of view, a synthesis is possible between socio-historical psychology and the sociology of knowledge of Berger and Luckmann in relation to the conception of society and the comprehension of the process of the constitution of the subject. Starting from the philosophical intentions of socio-historical psychology, it is possible to incorporate, enriching points such as: Berger s and Luckmann sconception of society and the interpretation of the process of constitution of the subject. This possible synthesis, when interpreted in light of the reflections of Althusser and Sousa Filho on the phenomenon of ideology in human societies, is constituted in a real unveiling of the concrete provisos by which the ideology acts in human societies in order to transform biological examples of the human species in specific social subjects

O canto das senhoras :Análise do discurso do sujeito coletivo (DSC) de velhas mulheres da Ponta do Tubarão, no Rio Grande do Norte

The participation of women of more than 60 years of age in the social ritual of the creation of the Reserva de Desenvolvimento Sustentável Estadual ( Sustainable Development State Reserve ) at Ponta do Tubarão, in the state of Rio Grande do Norte, is the central object of this research. This work is an attempt to analyze the oral discourse of these women, to understand the historical participation in this ritual, pointing out the actions for dehistoricization that, in the Western world, take women out of the community scene making their roles less important or invisible as agents of social construction. The reflections that take place in this research, using as a starting point, the example of a traditional fishing community on the Brazilian coast, and denounce the mechanisms of male domination that try to silence their hábitus, such as: the discourse of power (that is responsible for the permanent division of sexual structures) and of the correspondent social and cultural division. The present research respects the oral discourse of the Elderly Women as a significant practice of community life in Diogo Lopes in Macau, Rio Grande do Norte. The creation of the community of RDSE in Ponta do Tubarão as an instrument for political and social management is also accepted here as a process conducted by various social actors that react to developmental threats that have interfered with and are still trying to interfere with the equilibrium of the regional ecosystem. The methodology used in the research is supported in the oral discourse of these women as social representations of a focus group, on which the method of the Análise do Discurso do Sujeito Coletivo (DSC) ( Collective Subject Discourse Analysis ) is applied

Vida, experiência, conhecimento : a reforma do sujeito cognoscente em Tsunessaburo Makiguchi

Utilizing a great part of the works by Japanese educator Tsunesaburo Makiguchi and the register of fragments of his life, this thesis affirms that knowledge emerges from peoples` experience as they go about their daily lives. Facts, events, genetic inheritance, cultural patrimony, family history, the place where one was born and lived, and psychological predispositions nurture and form a vision of the world and of life in general. In Makiguchi s case, this multi-causal constellation led him to conceive the system of the value-creating pedagogy of good, gain and beauty; discussing the importance of cognition and evaluation in the experience of the human being. His life is exemplary in demonstrating that these aspects are inter-connected and, in a recursive movement between knowledge and self-knowledge, they can generate creative systems for understanding the world and introducing, essentially, the author into the epistemological problematic of complexity. The Makiguchian system and Edgar Morin s complexity approach suggest a pragmatic, paradigmatic reform of education and a thought reformation in the direction of the complex pedagogy, and that it creates a web that connects master-disciple, subject-object, human-world, local-global and singular-universal

O discurso formativo do Biólogo sobre a morte: matizes e metáforas do saber que o sujeito não deseja saber

This study - Biologist s formative speech about death. Nuances and metaphors from knowing that the subject of do not want to know - shows a marginal cognitive construction in scientific education from biologist - death. It considered as obvious that death is a theme that covers both the scientific education from biologist and the division of the subject, and concerns the splitting of the double life-death and the principles of inclusion and exclusion of the subject. Part of sensitive question: What is the epistemological weave who supports biologist's speech about death? It is constituted an object of study of the biologist s speech on death. It is advocated the thesis that: Death is an epistemological obstacle announcing for something always aims to escape from the perspective of knowledge, especially of scientific knowledge because, since it is understood as cognitive learning about the disruption of biological phenomenon life which is involved on weave of imaginary and symbolic constructions about the finiteness of life; it has constituted a metaphorical knowing - encouraged by the noisy silence - which does not allow to know in full, mobilizing hence subject in searching for transitional truths that reduce the ontological being-mortal anguish centered in subjective dimension involved in the act of knowing. From this movement of search that the object mental life after death wins a symbolic value that requires a real-looking multi-referential for the study of biology - life - and its implications: the finiteness of life, especially by moving the omnipotence of scientific objectivity expressed by signs and symbols that seek say the completeness of scientific knowledge-, signaling thus the existence of the dynamics of incompleteness implicit in subjectivity that supports knowledge relating to the double, life and death, and to the temporality of the existence of Homo sapiens sapiens, with the axis guiding the desire of the subject, do not want to know about death, implicit in the mechanisms objective-subjective founded by non-said of death is the epistemology of the existence of objective-subjective subject, whose core is the negation of death. The theoretical methodological knowing web is anchored in the multi-reference which favors a transit by theoretical current, as the Psychoanalysis, bachelardian philosophy, the epistemology of complexity, the Thanatology, the Social Psychology, and Etnocenology, and Understanding Interview. The unveiling of the study object from the analysis of oral speech of eleven biologists who serve in high school, from three main guiding: Death in the history of life,Death in biologist s academic education and, Conceptions about concepts

Os ateliês (auto)formativos na constituição do sujeito docente da educação matemática

The object of study of this thesis is the use of (self)training workshops as a fundamental process for the constitution of the teaching subject in mathematics education. The central purposes of the study were to describe and analyze a learning process of mathematics teachers supported by the training-research methodology, which procedures have been affected with the practice of (self)training workshops as a way of collaborating to the constitution of the teaching subject in Mathematics Education. The survey was conducted with a group of teachers in the city of Nova Cruz, Rio Grande do Norte through a process of continued education realized in the training workshops having as main goal the realization of the group s (self)training sessions in order to lead participants to the extent of their autonomy in their personal and professional transformations. The results obtained in the formative processes have shown the need to develop activities of mathematics teaching as a contribution to overcome the conceptual difficulties of the teachers, apart from their (self)reflections about themselves and the educational processes in which they belong. The results raised some propositions about (self)training workshops that may be incurred in practices to be included in the curriculum frameworks or materialize as a strategy of pedagogical work in training courses for teachers of mathematics. Also, they can constitute an administrative and educational activity to be instituted in the public schools of Basic Education

Passivo ambiental e o setor de exploração de petróleo em terra: abordagem teórica e percepção institucional dos impactos ambientais gerados na atividade

The search for a sustainable development is result of the exhaustion of the natural resources of the planet that demands globalizated politics with practical of compatible economic development with the protection of the quality of life for the future generations. This work presents a study on the thematic on the environmental liabilities in the organizations with focus in the industry of the oil and the production of oil in land in the state of Rio Grande do Norte. Some types of environmental liabilities are presented, as well as, some estimates techniques. Moreover, this work presents surveys of some variable that stimulate the organizations to implant technologies of reduction of the impacts in the environment as: the environmental legislation, costs, the main impacts of the production of oil in land. On the basis of the bibliographical research and in the identified variable, it was carried a case study with state and municipal technician that act in the sectors of fiscalization (IBAMA-RN and IDEMA-RN) with the objective to deepen the discussion regarding the impacts of the industry of the oil, the effectiveness of the current law, the performance of the institutions the federal level and how to prevent impacts in the environment. It was observed that the environmental liabilities are a little spread subject in the organizations, perhaps to be unknown and of few theoretical referencees at the national level, regarding to the evaluation techniques. At the same time, absentee in the national politics that conducts the oil exploration

Metodologia de análise e diagnóstico de fratura em um componente automotivo sujeito a cargas cíclicas alternadas

The competitiveness of the trade generated by the higher availability of products with lower quality and cost promoted a new reality of industrial production with small clearances. Track deviations at the production are not discarded, uncertainties can statistically occur. The world consumer and the Brazilian one are supported by the consumer protection code, in lawsuits against the products poor quality. An automobile is composed of various systems and thousands of constituent parts, increasing the likelihood of failure. The dynamic and security systems are critical in relation to the consequences of possible failures. The investigation of the failure gives us the possibility of learning and contributing to various improvements. Our main purpose in this work is to develop a systematic, specific methodology by investigating the root cause of the flaw occurred on an axle end of the front suspension of an automobile, and to perform comparative data analyses between the fractured part and the project information. Our research was based on a flaw generated in an automotive suspension system involved in a mechanical judicial cause, resulting in property and personal damages. In the investigations concerning the analysis of mechanical flaws, knowledge on materials engineering plays a crucial role in the process, since it enables applying techniques for characterizing materials, relating the technical attributes required from a respective part with its structure of manufacturing material, thus providing a greater scientific contribution to the work. The specific methodology developed follows its own flowchart. In the early phase, the data in the records and information on the involved ones were collected. The following laboratory analyses were performed: macrography of the fracture, micrography with SEM (Scanning Electron Microscope) of the initial and final fracture, phase analysis with optical microscopy, Brinell hardness and Vickers microhardness analyses, quantitative and qualitative chemical analysis, by using X-ray fluorescence and optical spectroscopy for carbon analysis, qualitative study on the state of tension was done. Field data were also collected. In the analyses data of the values resulting from the fractured stock parts and the design values were compared. After the investigation, one concluded that: the developed methodology systematized the investigation and enabled crossing data, thus minimizing diagnostic error probability, the morphology of the fracture indicates failure by the fatigue mechanism in a geometrically propitious location, a tension hub, the part was subjected to low tensions by the sectional area of the final fracture, the manufacturing material of the fractured part has low ductility, the component fractured in an earlier moment than the one recommended by the manufacturer, the percentages of C, Si, Mn and Cr of the fractured part present values which differ from the design ones, the hardness value of the superior limit of the fractured part is higher than that of the design, and there is no manufacturing uniformity between stock and fractured part. The work will contribute to optimizing the guidance of the actions in a mechanical engineering judicial expertise
