No caleidoscópio o estresse da equipe de enfermagem da UTI de um Hospital Universitário em Natal-RN

This study aimed to analyze stress on nursing staff of intensive care at the Teaching Hospital Onofre Lopes. The study sample consisted of thirty-eight (38) nursing professionals, including technicians and nurses working in the ICU of the hospital Data were collected between September to November 2011 in two stages.The first was the application of the Lipp Stress Symptoms Inventory (LSSI), which allowed us to measure the stress phase in which each team member was. After that, data were tabulated in Microsoft Excel spreadsheets and analyzed according to the 2010 inventory guidelines proposed by the author. After this analysis it was possible to complete the second phase of the research, which consisted of a semi-structured interview designed for those workers who were in the second phase of stress, resistance. Data analysis was based on Bardin 2004 content analysis, enabling the creation of categories based on grouping the ideas present in the interviewees' statements. It was found that the study population was mostly female (78.9%) aged from 30 to 39 years (50%), married (52.3%) and with dual-employment (65.7%). The most predominant phase, according to the Lipp inventory, was the stress resistance, present in 44.7% of the team and having as most predominant physical symptoms the constant feeling of physical exhaustion, verified in 16.8% of the participants, and psychological, the excessive irritability and emotional sensitivity in 26.3%. Regarding the qualitative data it was possible to establish three categories and four subcategories, with the following categories: the stressors of the workplace, overwork and the interpersonal relationships of the nursing staff in the ICU. And as subcategories: Routine care in the ICU; Pressures and Individual Charges; double journey: professional reflections on daily life, the night shift nursing staff and the body suffers, the manifestations of stress; deficient communication between team members. Thus, this study allowed the visualization of the stress phenomenon on nursing staff of the Teaching Hospital Onofre Lopes as a kaleidoscope of thoughts, feelings and experiences perceived by these professionals in different areas of their lives. It was also verified that the strengthening of the stress theme among nursing professionals need to be exploited and stimulated in several nursing areas of discussion so these workers are encouraged to take better care of themselves so they can take care of others health

Análise do modelo de gestão implantado no Centro de Atenção Psicossocial CAPS II OESTE de 1995 a 2005, situado no distrito sanitário Oeste do município de Natal/RN, à luz da Co-gestão

This dissertation has as aim the praxis of co-management of the health service of CAPS II OESTE of Natal-RN, where health workers, family members got to materialize guidelines and principles of psychiatric Brazilian reform in real possibilities of subjectivity construction, whereas they changed social relations in daily life. The path chosen to record was from testimonials and contributions of those who meant their done. Redeeming this story from social representations of the majority of their builders was an instigating, delicate and rewarding task, emphasizing the living memory, rebuilt in a line of time which could not be found in simple documentary collections. Mainly, by knowing that service routine was intense and had as characteristic the singular mobility itself from a creation process and therefore not always its dynamic allowed adequate records. At the same time, from this occurred the field and bibliographic research which allowed the detailed information from the prior milestones and motivated to the practice here reported. The rereading of concepts in an interface with the reports of the interviewees enabled the verification that the model of mental health advocated by psychiatric reform was understood. Once noticed the presence of the beliefs and values of people in motivating energy for the progress of reform, it has gone to fetch theoretical subsidies of administrative order to understand how they saw this building and that uniqueness has been printed. The theoretical way and praxis have tracked here has allowed to analyze how occurred such a process of production and subjectivity and collectives that when organize enabled themselves for analysis and intervention, including in crisis situations. Therefore, it was revealed that ethical and multi-disciplinarity, the humanitarian sense, the coresponsibility, co-production and horizontal management were the key factors for spread from a changing protagonist. One can thus conclude that co-management from that collective has been multi-disciplinary weaving a cross

Análise dos indicadores de qualidade versus taxa de abandono utilizando método de regressão múltipla para serviço de banda larga

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

Avaliação da usabilidade de Websites de hotéis segundo as heurísticas de Nielsen: pesquisa exploratória em hotéis da Região Rordeste do Brasil

This Thesis deals with the usability in some sites of hotels placed in a specific region of Brazil. Usability is the property of a site that shows how it allows the user get all information available without a large effort and in a clear and objective way. A questionnaire was used as a tool to value, by the common user perspective, navigation, on line reservation simulation, appreciation of the available content and, by this way, an easiness in the interaction site-users. As a result, it is possible to say that, considering all material analyzed, those sites that present usability criterion are more interactive and dynamic, demonstrating an easy navigation in a users view. By other side, it was possible to note that, about heuristics used in the search, the most of the websites demonstrated a deficiency in questions as firmness, user control and how to avoid mistakes. There was still valued as deficiency by the most of users in websites the general characters and the view of user. It was presented, seeing general characters, that a big part of the websites needs tools that can make user rapidly find what looks for. It was yet possible to see that users don't believe in secret when websites ask them some information. This is a point that needs to be appreciated because it causes some insecurity during navigation

Obtenção e caracterização de um compósito de poliuretano de mamona e pó de vidro para aplicações em insolantes térmicos

Thermal insulation is used to protect the heated or cooled surfaces by the low thermal conductivity materials. The rigid ricin polyurethane foams (PURM) are used for thermal insulation and depend on the type and concentration of blowing agent. Obtaining PURM occurs by the use of polyol, silicone, catalyst and blowing agent are pre -mixed, reacting with the isocyanate. The glass is reusable, returnable and recyclable heat insulating material, whose time of heat dissipation determines the degree of relaxation of its structure; and viscosity determines the conditions for fusion, operating temperatures, annealing, etc. The production of PURM composites with waste glass powder (PV) represents economical and renewable actions of manufacturing of thermal insulating materials. Based on these aspects, the study aimed to produce and characterize the PURM composites with PV, whose the mass percentages were 5, 10, 20, 30, 40 and 50 wt%. PURM was obtained commercially, while the PV was recycled from the tailings of the stoning process of a glassmaking; when the refining process was applied to obtain micrometer particles. The PURM + PV composites were studied taking into account the standard sample of pure PURM and the influence of the percentage of PV in this PURM matrix. The results of the chemical, physical and morphological characterization were discussed taking into account the difference in the microstructural morphology of the PURM+PV composites and the pure PURM, as well the results of the physicochemical, mechanical e thermophysical tests by values obtained of density, hardness, compressive strength, specific heat, thermal conductivity and diffusivity. In general, the structure of pure PURM showed large, elongated and regular pores, while PURM+PV composites showed irregular, small and rounded pores with shapeless cells. This may have contributed to reducing their mechanical strength, especially for PURM - PV50. The hardness and density were found to have a proportional relationship with the PV content on PURM matrix. The specific heat, thermal diffusivity and thermal conductivity showed proportional relationship to each other. So, this has been realized that the increasing the PV content on PURM matrix resulted in the rise of diffusivity and thermal conductivity and the decrease of the specific heat. However, the values obtained by the PURM composites were similar the values of pure PURM, mainly the PURM-PV5 and PURM-PV10. Therefore, these composites can be applied like thermal insulator; furthermore, their use could reduce the production costs and to preserve the environment

As Ciências Espaciais, o saber e o fazer docente no ensino fundamental

This study aims to include topics related to Space Science in elementary education from an experiment that aims to rescue the science teachers in public schools of São Tomé, RN, a taste for experimentation and exploration of advanced technologies. During this research with teachers found that they knew enough about the subject, but this knowledge was restricted to the events disclosed by the media. Regarding scientific knowledge, that same surface, they had many conceptual difficulties which hindered the approach of these topics in their classes. To overcome this difficulty, a workshop was held where teachers had the opportunity to discuss the historical aspect of Space Science, some physical concepts related to it, and the conduct of experiments with PET bottle rockets that recover from the curiosity typical of how the science. The results were outlined in the form of Planning Didactic built by teachers and using themes related to space science, from there, discussing content already provided in the composition of the schools curriculum. Therefore, this work allowed the teachers a minimum training required for them to not only reproduce, but readjusted and build, from this, their own paths in the classroom at the fundamental level

Luna Clara e o Apolo Onze do arquivo ao repertório : o limiar de uma transescritura em Adriana Falcão

La palabra archivo tiene origen en el vocablo griego arkhê, en lo cual puede indicar comienzo y comando. Tal palabra puede ser usada para representar distintas ideas. Al ser considerada como un conjunto, puede reunir las informaciones existentes sobre un determinado asunto en cualquier área del conocimiento humano.(DERRIDA, 2001) Esas informaciones, por su vez, son constantemente modificadas por el repertorio de los usuarios de eses archivos. Cada individuo, al usar ese repertorio, lo hace de una manera diferente, pues las posibilidades son variadas. Entre estas, está la performance, que permite la elaboración de una transescritura, un modo de escribir que va más adelante del padrón convencional. Para que sea comprendida como tal, la escritura necesita realizar una transgresión, quebrar el canónico.(RAVETTI,2003) Adriana Falcão transgride, al consultar el archivo y reinventarlo a partir de su propio repertorio, llegando a realizar una transescritura. En el romance Luna Clara e Apolo Onze (2002). En este, archivo y repertorio están en constante mescla, criando nuevas relaciones entre literatura, historia, mitologia, lengua, artes, temas humanos y sociales. El romance es entonces percibido como una narrativa que performatiza nombres, hogares, conceptos, ideas, a través de una marca que por ser tan plural es única, peculiar, representación de la literatura infante-juvenil del siglo 21

Efeitos do esteróide anabólico nandrolona sobre o músculo sóleo de ratos submetidos a treinamento físico através de natação: estudo histológico, histoquímico e morfométrico

Este estudo teve por objetivo analisar as alterações histológicas, histoquímicas e morfométricas das fibras do músculo sóleo de ratos submetidos a um programa de natação, associado ou não à administração do esteróide anabólico decanoato de nandrolona. Foram utilizados 22 ratos Wistar machos, 12 dos quais receberam injeção intramuscular do esteróide (5mg/kg) e 10, óleo mineral (5mg/kg), duas vezes por semana. Os animais foram submetidos a 42 sessões de natação por nove semanas (de segunda a sexta-feira), com aumento progressivo de carga por meio do tempo de natação. Após o sacrifício, o músculo sóleo esquerdo foi retirado, imerso em n-hexana e acondicionado em nitrogênio líquido. Cortes do terço médio desse músculo foram feitos em micrótomo criostato (-20ºC) e corados pela técnica HE e pelo método histoquímico NADH-TR. Os animais submetidos a treinamento físico e a esteróide (TA) ou óleo mineral (TO) apresentaram fibras musculares com maior diâmetro, quando comparados com os animais-controle (NTA e NTO). Não houve diferença significativa entre as medidas das médias dos diâmetros das fibras dos grupos NTA e NTO e entre TA e TO. Nos grupos TA e NTA notou-se acentuado processo de fagocitose, arredondamento e hialinização das fibras musculares. Já nos grupos TA, TO e NTA observou-se perda da atividade enzimática oxidativa. Os resultados sugerem que a natação produz hipertrofia muscular de forma semelhante, tanto no grupo que recebeu esteróide como no que recebeu óleo mineral. No entanto, o grupo que recebeu esteróide apresentou sinais claros de maior degeneração muscular.

Efeitos do exercício aeróbio no músculo esquelético de ratos expostos à fumaça de cigarro

INTRODUÇÃO: Os fumantes sofrem redução da massa muscular e da resistência à fadiga e possivelmente a prática de atividade física contribua positivamente neste quadro. OBJETIVO: Este estudo teve por objetivo analisar as adaptações da musculatura esquelética frente à interação da prática de atividade física e exposição à fumaça de cigarro. MÉTODOS: 32 ratos machos foram divididos em grupos expostos à fumaça de cigarro, exercitados (G1) e sedentários (G3), e não expostos à fumaça, exercitados (G2) e sedentários (G4). A exposição à fumaça foi realizada mediante combustão de 10 cigarros em uma câmara de inalação durante 30 minutos, duas vezes ao dia, cinco dias por semana, durante 15 dias; o exercício aeróbio foi composto por sessões diárias de 60 minutos de caminhada em esteira, cinco dias por semana. Após o sacrifício, o músculo sóleo foi coletado e seus cortes foram corados pela técnica de HE e submetidos ao método histoquímico NADH-TR. RESULTADOS: O grupo G1 apresentou maior quantidade de alterações musculares, bem como ausência de atividade enzimática, o mesmo ocorrendo no G3, porém com menor intensidade; no G2 foi observado padrão normal para fibras exercitadas, estando as fibras do G4 preservadas. Quanto à morfometria, houve diferença significante para o fator exercício (p = 0,007), enquanto não foram observadas diferenças significantes para o fator exposição à fumaça (p = 0,668) e para a interação exposição à fumaça e exercício (p = 0,077). CONCLUSÃO: A interação entre inalação de fumaça de cigarro e exercício, realizada durante 15 dias em ratos machos Wistar adultos, acentuou as alterações histológicas do músculo sóleo, levando a uma alteração da atividade enzimática e acarretando em aumento do diâmetro das fibras musculares

Efeito da técnica de oscilação oral de alta freqüência aplicada em diferentes pressões expiratórias sobre a função autonômica do coração e os parâmetros cardiorrespiratórios

O objetivo deste estudo foi avaliar o efeito da técnica de oscilação oral de alta freqüência (com o aparelho Shaker), aplicada em diferentes pressões expiratórias (PE), sobre a função autonômica e parâmetros cardiorrespiratórios. Foram coletados dados de 20 voluntários jovens saudáveis (21,6±1,3 anos), que permaneceram em repouso inicial por 10 minutos e, em seguida, fizeram três séries de dez expirações no aparelho (com intervalo de descanso de 2 minutos entre as séries) em três diferentes PE - pressão livre (PL), de 10 (P10) e de 20 (P20) cmH2O - permanecendo por mais 10 minutos em repouso final. Os dados foram analisados estatisticamente, com nível de significância de 5%. Após a aplicação da técnica, constatou-se diferença significante nos índices de variabilidade da freqüência cardíaca em PL e um aumento significante na pressão arterial sistólica em P20. Na pressão arterial diastólica, freqüência respiratória e saturação periférica de oxigênio não foram encontradas diferenças antes, durante e após a técnica, nas diferentes PE. A percepção do esforço aumentou significantemente ao longo das séries em PL e P20 e entre P10 e P20 em cada série. A freqüência cardíaca (FC) aumentou e diminuiu em sincronia com os movimentos de inspiração e expiração, respectivamente. Foram observadas modificações na modulação autonômica do coração em PL. A aplicação da técnica nessa população, nas diferentes PE analisadas, promoveu modificações no comportamento da FC, no esforço percebido e, em PL, na modulação autonômica do coração.

A morada do pensamento: um encontro com Platão na busca da natureza do sentido em Frege

The ontological investigation of sense, from German philosopher Gottlob Frege s point of view, has, as its foundation, the understanding of reference, representation, thought and sense s categories. According to Frege s writings, On Sense and Reference, and Thoughts Logical Investigations, sense carries itself the solution for the problem of identity s relation. Sense gives us the knowledge s increment that identity doesn t give. But still there is a problem: the definition of sense's nature. Sense couldn t have its nature strictly defined because, in this case, it would be reduced to reference s category and thus, sense would be identified with the own extra-linguistic object, and this is a misconception. But Frege said that thought must be considered as the sense of the sentence. So, with this close relationship between sense and thought, a new goal in this investigation is putt in focus: thought. To Frege, thought is not a simple subjective performance of thinking, it is not a subjective representation, but it is an objective content that is real, eternal, and that exists by itself in a third realm . Thought exists in a realm beyond the world of subjective representations and beyond the world of sensible perception. From this point, the present investigation went back to Plato s World of Ideas. So, the platonic thinking was included in this debate about the metaphysic of the third realm in Frege, trying to clarify the original concepts of knowledge, reality and truth. To achieve this objective, the following dialogues had been included in our research: Theaetetus, Republic and Phaedo. And the following fregean questions had been brought to Plato's scope: how happens the new knowledge? What is the third realm s reality? What is the relation between truth and thought? Doing that we could see as much some of the platonic origins of Frege's approach, as some differences between this two philosophers

Histological evaluation of the lesion induced by inoculation of Leishmania mexicana in the cheek pouch of the hamster

No presente estudo, investigamos o papel da resposta imune na morfologia do granuloma leishmaniótico induzido na bolsa jugal do hamster, um local imunologicamente privilegiado, após inoculação de 3x10(5) Leishmania mexicana. Os animais foram avaliados histológica e imunologicamente até os 120 dias da inoculação. Independente da época do sacrifício, os animais foram sempre não reatores ao teste do coxim plantar. Histologicamente, a inoculação de Leishmania mexicana na bolsa jugal resultou na formação de abcesso que evoluiu para reação granulomatosa rica em formas amastigotas e, posteriormente, para resolução. Esses resultados sugerem que o desenvolvimento da resposta imune não é preponderante no controle da infecção induzida pela Leishmania mexicana inoculada subcutaneamente na bolsa jugal do hamster. Sugerem ainda que os macrófagos que compõe os granulomas leishmanióticos são capazes de eliminar esse parasita, independente da presença de resposta imune avaliável pelo teste do coxim plantar.

Avaliação da capacidade de caminhar do portador de obesidade mórbida utilizando teste de caminhada de 6 minutos

Introduction: The ability to walk is impaired in obese by anthropometric factors (BMI and height), musculoskeletal pain and level of inactivity. Little is known about the influence of body adiposity and the acute response of the cardiovascular system during whole the 6-minute walk test (6mWT). Objective: To evaluate the effect of anthropometric measures (BMI and WHR waist-to-hip ratio), the effort heart and inactivity in ability to walk the morbidly obese. Materials and Methods: a total 36 morbidly obese (36.23 + 11.82 years old, BMI 49.16 kg/m2) were recruited from outpatient department of treatment of obesity and bariatric surgery in University Hospital Onofre Lopes and anthropometric measurements of obesity (BMI and WHR), pulmonary function, pattern habitual physical activity (Baecke Questionnaire) and walking capacity (6mWT). The patient was checking to measure: heart rate (HR), breathing frequency (BF), peripheral oxygen saturation, level of perceived exertion, systemic arterial pressure and duplo-produto (DP), moreover the average speed development and total distance walking. The data were analysed between gender and pattern of body adiposity, measuring the behavior minute by minute of walking. The Pearson and Spearmam correlation coefficients were calculated, and stepwise multiple Regression examined the predictors of walking capacity. All analyses were performed en software Statistic 6.0. Results: 20 obese patients had abdominal adiposity (WHR = 1.01), waist circumference was 135.8 cm in women (25) and 139.8 cm in men (10). Walked to the end of 6mWT 412.43 m, with no differences between gender and adiposity. The total distance walked by obesity alone was explained by BMI (45%), HR in the sixth minute (43%), the Baecke (24%) and fatigue (-23%). 88.6% of obese (31) performed the test above 60% of maximal HR, while the peak HR achieved at 5-minute of 6mWT. Systemic arterial pressure and DP rised after walking, but with no differences between gender and adiposity. Conclusion: The walk of obese didn´t suffers influence of gender or the pattern of body adiposity. The final distance walked is attributed to excess body weight, stress heart, the feeling of effort required by physical activity and level of sedentary to obese. With a minute of walking, the obeses achieved a range of intensity cardiovascular trainning

Comparação das respostas fisiológicas entre diferentes testes funcionais em obesos

obesity affects rightly functional capacity diminishing the cardiovascular system efficiency and oxygen uptake (VO2). Field tests, such as, Incremental Shuttle Walking Test (ISWT) and Six Minute Walk Test (6MWT) has been employed as alternative of Cardiopulmonary Exercise Test (CPX), to functional assessing for conditions which transport of oxygen to peripheral is diminished. Nevertheless, the knowing about metabolic variables response in real time and it comparing among different maximal and submaximal tests in obese is absent. Aim: to compare cardiopulmonary, metabolic response during CPX, ISWT and 6MWT and to analyse it influence of adiposity markers in obese. Material e Method: crosssectional, prospective study. Obese included if: (BMI>30Kg/m2; FVC>80%), were assessed as clinical, anthropometric (BMI, body adiposity index-BAI, waist-WC, hip- HC and neck-NC circumferences) and spirometry (forced vital capacity-FVC, Forced expiratory volume-1°second-FEV1, maximal voluntary ventilation-MVV) variables. Obese performed the sequence of tests: CPX, ISWT and 6MWT. Throughout tests was assessed breath-by-breath by telemetry system (Cortex-Biophysik-Metamax3B) variables; oxygen uptake on peak of activity (VO2peak); carbon dioxide production (VCO2); Volume Expiratory (VE); ventilatory equivalents for VO2 (VE/VO2) and CO2 (VE/VCO2); respiratory exchange rate (RER) and perceived effort-Borg6-20). Results: 15 obese (10women) 39.4+10.1years, normal spirometry (%CVF=93.7+9.7) finished all test. They have BMI (43.5+6.6kg/m2) and different as %adiposity (BAI=50.0+10.5% and 48.8+16.9% respectively women and men). Difference of VO2ml/kg/min and %VO2 were finding between CPX (18.6+4.0) and 6MWT (13.2+2.5) but not between ISWT (15.4+2.9). Agreement was found for ISWT and CPX on VO2Peak (3.2ml/kg/min; 95%; IC-3.0 9.4) and %VO2 (16.4%). VCO2(l/min) confirms similarity in production for CPX (2.3+1.0) and ISWT (1.7+0.7) and difference for 6MWT (1.4+0.6). WC explains more the response of CPX and ISWT than other adiposity markers. Adiposity diminishes 3.2% duration of CPX. Conclusion: ISWT promotes similar metabolic and cardiovascular response than CPX in obese. It suggesting that ISWT could be useful and reliable to assess oxygen uptake and functional capacity in obese
