Atendimento Pré-hospitalar Móvel. Mapeando Riscos e Prevenindo Erros

The attention with safety of the patients is important in the quality of the nursing and health care. In the pre-hospital care, such care is essential on site with the purpose of avoiding possible consequences to the individual, ensuring a fast and appropriate care, with improvement of the morbidity and reduction of the mortality. This medical attention is equally associated with the significant risks of adverse events and serious mistakes, which can be reduced with the awareness of the professionals, organization and quality management. It is a descriptive, transversal research, of quantitative approach, with the objective of identifying the risks for the safety of the patient during the mobile pre-hospital care under the view of the nurses, in a city of the Brazilian Northeast. The sample was formed by 23 nurses. The inclusion criteria: to have at least two years of experience and accept to participate on the research. The data collection was done in two steps, first photo collection, through the adapted method of photographic analysis, and the second with the application of questionnaire, divide in two parts: socio-professional data and digital photo punctuation instrument of the patient s safety. The majority of the nurses had an average working time in the mobile pre-hospital care of six years and six months, in the age group of 38 to 53 years old (69,56%) and with Lato sensu specialization (73,91%), being (29,41%) emergency and (29,41%) in intensive care. The (74%) have the Advance Cardiac Life Support (ACLS) and (100%) have the Pre-Hospital Trauma Life Support (PHTLS); (91, 30%) know the thematic safety of the patient. On the pictures it was observed a bigger variability of the categories (risks) where 44% of variance emerged on the first picture of the research. The pictures 4 and 9 with the average below 5 were classified as very insecure, while pictures 7 and 3 with an average above 7, very secure. On the results of risks observed for the patient s safety in the mobile pre-hospital care five categories emerged: organization and packaging of the equipment and materials, routines and specificities in the mobile pre-hospital care, risks on the management of medications, for traumas and infections. Starting from the analysis of these risks, it was proposed ten steps for the safety in the mobile pre-hospital care: 1- Identify the patient; 2- Safety related to prevention of infection; 3- Safety in the management of medications; 4- Safety and standardization of the packaging of equipment and materials; 5- Attention to the specificities of the mobile pre-hospital care; 6- Incentive and value the participation of the patient and family; 7- Promote the communication with the central of regulation; 8- Prevention of traumas and falls; 9- Protect the skin from additional injuries; 10- Understand the benefit of all the equipment in the ambulance. The multiple risks and their emerged combinations on the research indicate a variety of actions to be developed and stimulated, like the use of steps for the patient s safety in the mobile pre-hospital care which contributes with the aid and management of risks, reduction of mistakes, disabilities and death

As origens históricas do Zaratustra nietzcheano: o espelho de Zaratustra, a correção do mais fatal dos erros e a superação da morte de Deus

Through a careful examination of the relationship between Zoroastrianism and the Western tradition, and a detailed and critical reading of the writings of Nietzsche, this work aims at showing to what extent the character Zarathustra , his discourses and poetical-philosophical thoughts, and related passages from many distinct Nietzschean works, directly or undirectly reflect a philosophy that harvests contributions from the Zoroastrian tradition or its headways (in the Judeo-Greco-Christian tradition, and furthermore in the whole Western philosophical tradition). Supplied with this provisions, and with the interpretation cast upon them, Nietzschean philosophy questions the entire Western tradition of thought, and proposes its replacement by a new attitude towards life. This work also intends to show the way the Nietzschean Zarathustra was built up, in the writings of the German philosopher, together with the idea of making, out of the namesake character of the ancient Iranian prophet (Zarathushtra or Zoroaster, the founder of Zoroastrianism), the herald of that important text that intended to bring the German language to its highest perfection , clumping together, and leading to a prophetic-poetic climax consonant with the meaning of the Earth , Nietzsche s key ideas about the rectification of the most fatal of errors and about the death of God . An elaborate investigation has been pursued after the reasons and manners of the building up of Nietzsche s Zarathustra mirroring its Iranian namesake (sections 1.1 to 1.6), and a survey of the works of Nietzsche has suggested unquestionable relations with the Zoroastrian tradition, mostly through the Jewish, Greek or Christian repercussions of this tradition. These relations have been put in context, in many framings (sections 2.1 to 2.3.2), in the ambit of the most fatal of errors - the - creation of morals in the very occasion of its transposition to metaphysics (Ecce Homo, Why I am a destiny , 3). Through an evaluation of the possible circumstances and repercussions of the death of God , the relations between Nietzsche s writings and Zoroastrian tradition have been investigated (sections 3.1 to 3.7), allowing the understanding of this event as an essential component, and tragic outcome, of the rectification of the most fatal of errors

Métodos numéricos para resolução de equações diferenciais ordinárias lineares baseados em interpolação por spline

In this work we have elaborated a spline-based method of solution of inicial value problems involving ordinary differential equations, with emphasis on linear equations. The method can be seen as an alternative for the traditional solvers such as Runge-Kutta, and avoids root calculations in the linear time invariant case. The method is then applied on a central problem of control theory, namely, the step response problem for linear EDOs with possibly varying coefficients, where root calculations do not apply. We have implemented an efficient algorithm which uses exclusively matrix-vector operations. The working interval (till the settling time) was determined through a calculation of the least stable mode using a modified power method. Several variants of the method have been compared by simulation. For general linear problems with fine grid, the proposed method compares favorably with the Euler method. In the time invariant case, where the alternative is root calculation, we have indications that the proposed method is competitive for equations of sifficiently high order.

O uso de analogias para o ensino de equilíbrio químico no ensino médio: facilitação da aprendizagem ou transmissão de erros conceituais?

The use of analogies in high school is often useful for chemistry teaching, either on textbooks or by teachers in the classroom.This use is justified by the large number of abstract concepts that rules this course. Analogies are conceptualized by several authors, which converge on the idea that these are tools that seek a way to elucidate an unknown concept by comparing it to a familiar one, relating their similar and dissimilar features. An analysis on a survey of analogies found in high school chemistry textbooks and chemical equilibrium studies is performed in order to verify whether they are leading to misconceptions for their use by students and/or for their use by teachers in the classroom, or whether they promote a learning facilitation

Desempenho de escolares de 1ª série na bateria de identificação de erros de reversão e inversão na escrita: estudo preliminar

OBJETIVO: caracterizar o desempenho de escolares da 1ª série na bateria de identificação de erros de reversão e inversão na escrita. MÉTODOS: participaram deste estudo 30 escolares de 1ª série de ensino público do município da cidade de Marília-SP, de ambos os gêneros, na faixa etária de 7 anos a 7 anos e 11 meses de idade. Como procedimento foi realizada a adaptação brasileira da bateria de identificação dos erros de reversão e inversão na escrita. Esta bateria é composta por 3 testes: teste de desempenho contínuo, teste de memória de curto prazo e teste de controle de escrita. Cada teste é composto por subtestes que visam identificar a capacidade dos escolares em identificar as inversões e reversões de letras e números isolados e letras e números em sequências. RESULTADOS: os resultados revelaram que os escolares da 1ª série apresentaram desempenho superior para identificação de reversão e inversão de letras dentro de palavras do que isoladamente, identificação da reversão para letras e números com desempenho superior se comparado a inversão de letras na palavra. Além disso, os escolares deste estudo apresentaram menor tempo para identificação de reversão e inversão de letras e números isolados do que em sequência. CONCLUSÃO: a Bateria adaptada para este estudo permitiu conhecer o perfil dos escolares de 1ª série quanto a identificação dos erros de inversão e reversão, entretanto, é necessário novas aplicações para verificar a ocorrência de identificação destes erros em populações de diferentes fase de alfabetização.

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

Modelo de Gompertz com sazonalidade e autocorrelação nos erros para ajuste do crescimento ponderal em vaca leiteira

In recent work (Kroll, 1990) on dairy cattle growth using its monthly weights, a Gompertz function, first considering the autocorrelated error structure, and second, the independent error structure, was fitted. The last explained 25% more of the total variance than the former. In this work, a Gompertz function was fitted with autocorrelated error structure adding seasonality to the model. This was suggested taking into account the time series autocorrelation function. In order to estimate the six parameters, an iterative procedure was used, employing a matrix X = [G\S], where G is the usual matrix for fitting the Gompertz function, and S is a 0s, 1s, -1s matrix necessary to take into account seasonality. With this model, the adjustment was better in terms of the coefficient determination.
