Compreensão do típico ideal de técnicos de enfermagem acerca da sistematização da assistência de enfermagem

This study aimed to understand the typical ideal of the nursing technician about the systematization of nursing care in the light of the theoretical framework of Alfred Schutz. It is a comprehensive phenomenological research, using the theoretical framework of Alfred Schutz. For the unveiling of the phenomenon (the typical ideal of the nursing technician about the systematization of nursing care), the search process was configured from the proposed guiding principles for a research methodology based on the work itself of Schutz held by Zeferino (2010) in his PhD. For data collection, we used the focus group technique, counting on the collaboration of thirteen practical nurses working in a university hospital in Rio Grande do Norte, who responded positively to the inclusion criteria: working in the study hospital, performing care direct to patients. Forty-four subjects showed interest in participating, being held a draw for selection of the research sample, consisting of 14 professionals, one of whom did not attend the gathering of data collection. The focus group, entitled "What I think about the systematization of nursing care", took place on February 15th, 2013, totaling 101 minutes. It was performed according to the Experiential Education Humanescent using building posters as projective technique, from the key question: "What is the systematization of nursing care for you?". In order to understand some of the biographical situation of the participants, a questionnaire was administered to study participants. From the agreement of the subjects, the focus group was recorded and photographed with the cooperation of one reporter and two other employees. We used Microsoft Word 2010 to perform the transcript of the meeting and Microsoft Excel 2010 for synthesizing the results via a spreadsheet. The study followed the ethical and legal principles that govern scientific research on humans, recommended in Resolution nº 196/96, it was approved by Opinion Embodied Ethics Committee in Research of UFRN (Federal University of Rio Grande do Norte), nº 98 424, of August 31th, 2012, CAAE No. 05906912.0.0000.5537. The analysis of the nursing staff speeches, along with the contemplation of their posters and their written descriptions, allowed from the guiding principles of Zeferino (2010), in light of the reference of Alfred Schutz, unveiling the typical ideal of nursing technicians about the systematization of nursing care, passing four themes: typing of the concept of systematization of nursing care; benefits, which resulted in the reasons to believe in the positivity of this working tool; experienced problems, revealing the world of everyday life of nursing professionals, and possibilities for improvement. It was concluded that the nursing technicians are unaware of the systematization of nursing care. However, they typify a very positive perception about the same, especially with regard to improvements that may foster care

Vivência do enfermeiro no cuidado humano na Unidade de Terapia Intensiva adulto

The purpose of the study was to understand the nurse s experience with human care in the Adult Intensive Care Unit (ICU). The objective was to describe the nurse s experience in caring for patients in the ICU and to analyze the nurse s perception of the care provided. The study is a descriptive inquiry of qualitative nature with a phenomenological approach. We interviewed eight nurses, 26 and 43 years of age, that provide care in the ICU of a private hospital in Natal/RN, during the manths of July and August of 2006. We analyzed the data acording to the method of Colaizzi. Four categories emerged from the data: The search for the maintenance of life, The technicalbureaucratic activities, The recognition of the patient s individuality, and the expression of the nurse s feelings.The analysis allowed us to describe the lived experience of the nurse s care the ICU and to comprehend the structural elements of this experience. The results showed that the nurse s experience presents itself as a process of the several actions and feelings that occur while the social relations between the patient and the nurse develop. Finally, we understand that although the study shows an experience based on a biological model of health, these nurses possess an initial idea on how to reach humanized care in its essence, needing, however, of an institutional policy that favors this practice, an educational formation that prepares her to recognize her field of work as a place of continuous learning and an understanding of the health model as an ally in the search of humanized care

Recuperação e purificação de quitosanases usando adsorção em leito expandido com streamline DEAE com modelagem e simulação usando redes neurais

Expanded Bed Adsorption (EBA) is an integrative process that combines concepts of chromatography and fluidization of solids. The many parameters involved and their synergistic effects complicate the optimization of the process. Fortunately, some mathematical tools have been developed in order to guide the investigation of the EBA system. In this work the application of experimental design, phenomenological modeling and artificial neural networks (ANN) in understanding chitosanases adsorption on ion exchange resin Streamline® DEAE have been investigated. The strain Paenibacillus ehimensis NRRL B-23118 was used for chitosanase production. EBA experiments were carried out using a column of 2.6 cm inner diameter with 30.0 cm in height that was coupled to a peristaltic pump. At the bottom of the column there was a distributor of glass beads having a height of 3.0 cm. Assays for residence time distribution (RTD) revelead a high degree of mixing, however, the Richardson-Zaki coefficients showed that the column was on the threshold of stability. Isotherm models fitted the adsorption equilibrium data in the presence of lyotropic salts. The results of experiment design indicated that the ionic strength and superficial velocity are important to the recovery and purity of chitosanases. The molecular mass of the two chitosanases were approximately 23 kDa and 52 kDa as estimated by SDS-PAGE. The phenomenological modeling was aimed to describe the operations in batch and column chromatography. The simulations were performed in Microsoft Visual Studio. The kinetic rate constant model set to kinetic curves efficiently under conditions of initial enzyme activity 0.232, 0.142 e 0.079 UA/mL. The simulated breakthrough curves showed some differences with experimental data, especially regarding the slope. Sensitivity tests of the model on the surface velocity, axial dispersion and initial concentration showed agreement with the literature. The neural network was constructed in MATLAB and Neural Network Toolbox. The cross-validation was used to improve the ability of generalization. The parameters of ANN were improved to obtain the settings 6-6 (enzyme activity) and 9-6 (total protein), as well as tansig transfer function and Levenberg-Marquardt training algorithm. The neural Carlos Eduardo de Araújo Padilha dezembro/2013 9 networks simulations, including all the steps of cycle, showed good agreement with experimental data, with a correlation coefficient of approximately 0.974. The effects of input variables on profiles of the stages of loading, washing and elution were consistent with the literature

Estudo da secagem do pedúnculo do caju em sistemas convencional e solar: modelagem e simulação do processo

This work aims to study the drying of cashew-nut pulp with different lay-out of dryers using conventional and solar energy. It concerns with the use of exceeding of the regional raw material and the suitable knowledge for the applicability of the drying systems as pathway for food conservation. Besides, it used renewable sources as solar energy to dry these agroindustrial products. Runs were carried out using a conventional tray-dryer with temperature, air velocity control and cashew slice thickness of 55°C, 65°C, 75°C; 3.0; 4.5, 6.0 m s-1; 1.0; 1.5 and 2.0 cm, respectively, in order to compare the studied systems. To evaluate the conventional tray-dryer, it was used a diffusional model of 2nd Fick´s law, where the drying curves were quite well fitted to an infinite flat plate design. For the drying runs where the room temperature had no control, it was developed a phenomenological-mathematical model for the solar dryer with indirect radiation under natural and forced convection based on material and energy balances of the system. Besides, it was carried out assays in the in natura as well as dehydrated, statistic analysis of the experimental drying data, sensorial analysis of the final dry product and a simplified economical analysis of the systems studied

Opiniões sobre estágio curricular e prática de ensino na licenciatura em química: o caso do CEFET-PB

The Brazilian legal documents are directing the reformulation of the courses that prepare students to be teachers. Through out the country many institutions look for to fit themselves in such documents. On the other hand, other IES (Superior Education Institutions), when they are setting up such courses they looked for to be adequate to the new public politics. Based on the National Curricular Norms to form teachers for Basic Education, in tertiary level, in 2004 it was created at the CEFET-PB,the Chemistry Course (Licenciatura) to prepare people to be teachers, whose organization. This work presents the results of a research of phenomenological nature that aimed to comprehend the teachers opinions, in the range of discussions about the current politics of formation, particularly related to the CNE/CP 1 and CNE/CP 2/2002 resolutions. This work based on the curricular proposal for the Chemistry Course (Licenciatura), presents the relationship between the probationary period and the teaching practice at the CEFET-PB, in order to contribute for a reflection about these categories to clarify the teachers of the course. It started from the consideration of all changes operated in contemporary society implies changes on teacher's pedagogical practices. It was used tow instruments for the data collection: a questionnaire with open and closed questions and recordable interviews. Nine teachers form the CEFET-PB took apart and four licensed teachers. It was based in a theoretic frame as a support for discussions about the different models of teachers formation. We concluded that the representations of teachers about probationary period the practice on the activity for the teachers formation was strongly anchored in characteristic elements of the formative tendency of a institution that historically acted on a technician formation, and the results pointed to strong signs of attitudes based on a model of the technical rationality

Filosofar em tempos de informação

This thesis reflects upon the question of how does philosophy think a particular today, which is not only a legitimate philosophical task but a determinative characteristic of philosophy in general. Today's thought follows two paths: first, an hermeneutical-phenomenological analysis of Martin Heidegger's thought with regards to his own contemporaneity; and secondly, through the analysis of the contemporary phenomenon of Information Technology which in the present work is to be considered a privileged sign of our times and distinctive of the mindfulness of philosophy. Therefore, the starting point is an investigation of Heidegger's thinking on his own era to whom facticity is a way of accessing the fundamental question of philosophy. This thesis is led by three guiding words which hold onto a perspective of unity in Heidegger s lifetime of work: 1. Technicity, 2. History, 3. Language, to thereby develop a characterization of human existence as 1. Technopolitical, 2. Technoscientific, and 3. Technological. Finally, in keeping with this triangular characterization of the human, a philosophical comprehension of our times will be established and drawn by Information Technology illustrating three of its' factual signs that are understood to be the 'Remains of Being' today: The Emptying of Speech (Language); The Emptying of Science (History); The Emptying of The Object (Technicity). Through these nowadays phenomenon, it is possible to maintain a grip on the fundamental question, precisely when the task of philosophy seems to have peremptorily lost its meaning and come to its logical end and to show how philosophizing in the information era is as possible as it is necessary.

Efeito Kerr magneto-óptico; Ressonância ferromagnética; Acoplamento bilinear; Acoplamento biquadrático

In this work, we investigated the magnetic properties of a monocrystalline Fe thin film and of Fe(80 Å)/Cr(t)/Fe(80 Å) tri-layers, with the nonmagnetic metallic Cr spacer layer thickness varying between 9 Å < t < 40 Å. The samples were deposited by the DC Sputtering on Magnesium Oxide (MgO) substrates, with (100) crystal orientation. For this investigation, experimental magneto-optical Kerr effect (MOKE) magnetometry and ferromagnetic resonance (FMR) techniques were employeed. In this case, these techniques allowed us to study the static and dynamical magnetization properties of our tri-layers. The experimental results were interpreted based on the phenomenological model that takes into account the relevant energy terms to the magnetic free energy to describe the system behavior. In the case of the monocrystalline Fe film, we performed an analytical discussion on the magnetization curves and developed a numerical simulation based on the Stoner-Wohlfarth model, that enables the numerical adjustment of the experimental magnetization curves and obtainment of the anisotropy field values. On the other hand, for the tri-layers, we analyzed the existence of bilinear and biquadratic couplings between the magnetizations of adjacent ferromagnetic layers from measurements of magnetization curves. With the FMR fields and line width angular dependencies, information on the anisotropy in three layers was obtained and the effects of different magnetic relaxation mechanisms were evidenced. It was also possible to observe the dependence of the epitaxy of the multilayers with growth and sputtering parameters. Additionally it was developed the technique of AC magnetic susceptibility in order to obtain further information during the investigation of magnetic thin films

Ondas de spin em nanofilmes nagnéticos acoplados quasiperiodicamente

We studied the spin waves modes that can propagate in magnetic multilayers composed of ferromagnetic metallic films in the nanometer scale. The ferromagnetic films (iron) are separated and coupled through the nonmagnetic spacer films (chromium). The films that make up the multilayer are stacked in a quasiperiodic pattern, following the Fibonacci and double period sequences. We used a phenomenological theory taking into account: the Zeeman energy (between the ferromagnetic films and the external magnetic field), the energy of the magneto-crystalline anisotropy (present in the ferromagnetic films), the energy of the bilinear and biquadratic couplings (between the ferromagnetic films) and the energy of the dipole-dipole interaction (between the ferromagnetic films), to describe the system. The total magnetic energy of the system is numerically minimized and the equilibrium angles of the magnetization of each ferromagnetic film are determined. We solved the equation of motion of the multilayer to find the dispersion relation for the system and, as a consequence, the spin waves modes frequencies. Our theoretical results show that, in the case of trilayers (Fe/Cr/Fe), our model reproduces with excellent agreement experimental results of Brillouin light scattering, known from the literature, by adjusting the physical parameters of the nanofilms. Furthermore, we generalize the model to N ferromagnetic layers which allowed us to determine how complex these systems become when we increase the number of components. It is worth noting that our theoretical calculations generalize all the results known from the literature

Crescimento de filmes nanométricos monocristalinos de Fe/MgO(100) por "SPUTTERING" DC

The research behind this master dissertation started with the installation of a DC sputtering system, from its first stage, the adaptation of a refrigerating system, passing by the introduction of a heating system for the chamber using a thermal belt, until the deposition of a series of Fe/MgO(100) single crystal nanometric film samples. The deposition rates of some materials such as Fe, Py and Cu were investigated through an Atomic Force Microscope (AFM). For the single crystal samples, five of them have the same growth parameters and a thickness of 250Å, except for the temperature, which varies from fifty degrees from one to another, from 100ºC to 300ºC. Three other samples also have the same deposition parameters and a temperature of 300ºC, but with thickness of 62,5Å, 150Å, and 250Å. Magneto-optical Kerr Effect (MOKE) of the magnetic curves measurements and Ferromagnetic Resonance (FMR) were made to in order to study the influence of the temperature and thickness on the sample s magnetic properties. In the present dissertation we discuss such techniques, and the experimental results are interpreted using phenomenological models, by simulation, and discussed from a physical point of view, taking into account the system s free magnetic energy terms. The results show the growth of the cubic anisotropy field (Hac) as the sample s deposition temperature increases, presenting an asymptotic behavior, similar to the characteristic charging curve of a capacitor in a RC circuit. A similar behavior was also observed for the Hac due to the increase in the samples thicknesses. The 250˚A sample, growth at 300°C, presented a Hac field close to the Fe bulk value

Reflexões sobre a formação clínica fenomenológico-existencial na era da técnica

Phenomenology is the focus of this study for its critique of the limits of positivist science, which guides most of the fields of study including Psychology. The clinical formation process in Psychology courses is especially difficult for students-interns who adopt phenomenology as their clinical framework. Such difficulty is due to the incompatibility between theory provided in Psychology courses a science traditionally based on paradigms of scientism , and the theoretical-methodological proposal adopted by the aforementioned approach. As a backdrop for our study, we carefully examined the thought of philosopher Martin Heidegger, especially the Era of Technique. This contemporary technicism society was studied so that we could understand the socio-cultural status where this formation lies. Thus, we questioned if this panorama upon which Clinical Psychology rests favors the development of a phenomenological attitude and a special look at the meanings of existence, as defined in phenomenological clinical practice. Knowing such limits, our research aimed at understanding the experience of formation of clinical psychologists who take part in internships in the field of phenomenology-existentialism. Such study was, then, a phenomenological-hermeneutic research based on Heideggerian ontology and used a semi-structured interview as access tool. Six students of the UFRN higher-degree Psychology course who were doing their supervised internship in clinical psychology and the referred approach took part in this research. The research revealed that the phenomenological-existential formation phase opens a door to discoveries on the part of the intern that transcend the dimension of the other, for they show a self disclosure while a person in the word. Despite the initial discomforts caused by the course curriculum itself and by the freedom for clinical practice, so characteristic of phenomenology, the narratives demonstrate that such difficulties may start a process of search for new meanings, which show a search for sharpening their practices and for a path in balance with the existence of the other

Não há você sem mim: histórias de mulheres sobreviventes de uma tentativa de homicídio

The murder-suicide (H / S) has been defined as a shocking crime in which a person takes the life of another and then kills himself within 24 hours. Set up as a gender violence, because men are in majority, the killers and the women victims. This study aims to understand the meanings of the experience of a H / S, from women who have survived this act. This study sets up as a hermeneutic phenomenological research, based on Heidegger`s ontology. We interviewed three survivors of H / S, whose narratives allowed to approach the senses present in their lives. The interviews were transcribed and interpreted in accordance with the hermeneutic circle, as proposed by Martin Heidegger. From the interviews of research participants perceive that these women have built their senses in stocks, represented the family foundation and the presence of a husband and children. This project that moved their lives toward the construction of modes-of-being. We noticed the presence of historicity constructing meanings for the existence of these women. We found reports of an experience of loving relationships characterized by strong jealousy, with the presence of fantasies of betrayal, and marked by a careful affective relationship that put them in the position of object possession of his companions. Reflect that such caring restricted their existence being-for-husband. So the senses that moved their stocks, which aimed his ways existential, was the creation of a family, a reference to their lives, to live a love, and care for the children. Therefore, beyond the already known aspects in studies on violence against women, which made these women continue to choose this relationship was the sense that they had for their existence. It is hoped that this study will contribute to the construction of a new look on violence against women, taking as a basis the Heideggerian hermeneutic phenomenology

Masculinidade a prova: um estudo de inspiração fenomenologico - hermeneutico sobre a infertilidade masculina

Culturally, childbearing is understood as a situation that subjects will experience at some point in their lives, especially people who are married or have a similar affectionate relationship. Thus, to realize the inability to meet such a fate seems to be a natural cultural trigger of suffering, frustration and feelings of inadequacy and helplessness. Specifically for men, infertility is closely related to loss of masculinity, virility. He fails in his role as a male. This study sought to understand the impact that infertility have on the existence of a man who receives such a diagnosis, both in self-image as in their marital, sexual and professional roles. This study sets up as a hermeneutic phenomenological research based on the ideas of the philosopher Martin Heidegger. Participants were seven heterosexual, married and infertile men. Two interviews were conducted. The analysis of the material included both the material of the narratives, as the affectation of the researcher when interacting with the participants and their narratives, through phenomenological-hermeneutic interpretation. The results corroborate the literature that states the difficulty of the men, immersed in a context that defines them as virile, powerful and invulnerable to worry about issues related to health and disease. The possibility of any condition that impairs the reproductive capacity exceeds the acceptable limits of daily life for these men, not being recognized as a model of masculinity present in the condition in which they recognize. This leads to questions about their masculinity, role in the marital relationship and their existence. Thus, to recognize themselves as infertile surpass a medical diagnosis and is associated with the construction of meaning for their existence from the approximation with the infertility condition, which helps in redirecting their choices, restoring the project to be self and allowing further recognition as men. In the marital relationship, doing what they can to ensure, theirs happiness. Through these actions, they remain playing the role of family provider, showing that they are able to protect their wives and taking in assisted reproduction or adoption of children viable alternatives to fulfill the desire to leave a legacy and give a child to their wives and to society. Another result observed, refers to the ontological condition of care that characterizes the human being. The ways in which men are treated socially demonstrates a type of care that focuses on the development of characteristics such as strength, virility and determination but does not allow them to cope with the suffering of emotionally difficult situations, such as the diagnosis of infertility. At the end, the study gives rise to reflections on the need to provide a 12 space for men and their expressions of suffering, as well as to recognize their ability to overcome the painful and difficult situations

Do útero à adoção: a experiência de mulheres férteis que adotaram uma criança

Even with all changes and ruptures related to the social roles that woman had performed, the literature had confirmed that the motherhood still configures it like one of the main roles that she hopes to play in some moment of her life. When the woman did not get pregnant or take ahead a pregnancy, some women find in adoption an alternative to play this role. This research aimed to understand the experience of being mother for adoption in the case of fertile women, but whose partner is infertile. Supported by existential-phenomenological theory, used it the narrative, how methodological instrument. Participated five women, whose adoption process followed the legal ways in the Youngness and Infancy Judgeship of Natal/RN. The results showed that in the selfish training, the woman to see herself how whose role principal is to generate children, although, she think that is natural her participation in others activities go out home too. In male infertile case is a tendency that the woman strikes the infertile status too. The adoption is an alternative to fulfill her desire of being a mother and, meanwhile, please her husband and guarantee the continuity of her love relationship. Through motherly care, the woman discover herself as a mother, what brings a new meaning for her live, independent of to generate a child. Though, exit frustration, sometimes, in association with suffering, on account of the pregnancy and childbirth absence. The end of the research suggests reflections that to become fulfilled herself as mother, the woman does not need, necessarily, to generate a child, being the maternity one of the uncountable possibilities that are shown, and that she can choose, or not, accomplish it

A experiência de adolescentes portadores de diabetes Mellitus Tipo 1: seus significados e sentido

Worldwide, the diabetes mellitus is considered a serious problem of public health; it also involves high costs for its treatment and its complications. Even though the onset of diabetes mellitus type 1 is on 5% to 10% of the diabetic population, it is the most aggressive type of anifestation; furthermore, it is the commonest chronic disease in childhood and adolescence. Such data show the importance of understanding the development of this disease from the moment the individual perceives it, according to their experience, observing the complexity of the phenomenon thoroughly. This study aimed to comprehend the experience of the adolescent with onset of diabetes mellitus type 1 in order to learn how these young individuals perceive and reason their place in the world when they experience this illness. The methodological strategy was based on qualitative research of phenomenological inspiration. We applied the main ideas of heideggerian ontology and some concepts of existential phenomenological psychology to guide our reflexive path. The participants were 10 young individuals (06 female and 04 male), ages between 15 and 18, under treatment in the city of Recife, Pernambuco. The methodological resource was the narrative, which allowed us access to the adolescents experience. The comprehension of the reports was based on the heideggerian hermeneutics, whose priority is the interpretation of the meaning expressed by the participants speech. The results showed that factors such as social, family, economic and cultural context greatly influence the perception and the way the individuals deal with, perceive and reason their experience. We noticed that the diabetes type 1 may often represent a limitation, but it does not make it impossible to be part of the world with others. The data show a significant affective ambivalence regarding the content more directly related to the disease. This demonstrates the unique way which each one gives meaning and reasons their condition of existence. This research points out the need to understand the complexity of this phenomenon in a more complete manner, considering the adolescent in their timely and historical context. We believe we can encourage thinking that may become actions which are more fit to the reality researched regarding all the parties involved with the subject, such as health professionals, adolescents, family, support programs and public health policies

Compreendendo a experiência de pessoas portadoras de transtorno mental: histórias de vidas severinas repletas de possibilidades

This study aims to understand the experience of people suffering from mental disorder. The patients are enrolled in a mental health ambulatory clinic in the city of Natal (RN). Mental disorders are growing rapidly in the contemporary world and are a source of intense mental suffering. Besides patients being strongly marked by a history of isolation and prejudice, they have been the target of real atrocities committed in the name of preservation of a supposed normality. The understanding and treatment of this disorder is influenced by cultural and historical inferences, depending on the period in which it is experienced. Semi-directed Interviews were conducted with a group of users, with the emphasis on giving voice to their uniqueness and individuality, highlighting how each one perceives his or her own experience. These were recorded and later transcribed by identifying the core of meanings. The results were analyzed under the gaze of the Humanist Phenomenology Existential perspective, which aims to unravel the phenomenon, without truths from volatility, highlighting the existence of the mental disorder as a way of living, being permeated by suffering mental and influenced by social problems, assuming contours very particular to each individual. Some progress has been perceived, even by users, with respect to the change of paradigm in the way of care, but still there is a consistent emphasis on medical and drug use. The changes point to the need for offering services to replace the asylum hospital model, and in addition to accept the bearer of mental disorder as a citizen, a bearer of rights who should be accepted and respected by society. Despite the pain expressed and its close liaison with suicide, their reports are full of perspectives and attitudes of confrontation facing life, pointing to new possibilities to be, recreating itself
