Simulación y competencias no técnicas en el contexto de emergencia pre-hospitalar: estudio cualitativo

Unidade de Monitorização em Indicadores de Saúde - UMISAbstract - To understand the importance that nurses assign to simulation in the development of non-technical skills in cardiac arrest event in pre-hospital setting. Background Nursing is projected in the future, developing a patient centred approach consistent with the values, needs and desires of patients, considering process of care as a complex intervention. Simulation based on scenarios is an opportunity to recreate this complexity in a virtual way, to develop the non-technical skills. Methods This study uses an inductive, interpretative and constructivist qualitative research. 7 nurses were interviewed. It was developed a thematic analysis content. Results Three themes were identified: Simulation scenarios in pre-hospital emergencies; The acquisition of knowledge to skills development and Construction of the virtual from the real Conclusions The interviewed nurses present weakness of knowledge about simulation types. Debriefing is relevant to the learning skills: critical thinking. thinking, clinical judgement and decision making.Resumo - Compreender a importância que os enfermeiros atribuem à simulação no desenvolvimento de competências não técnicas no evento paragem cardíaca em ambiente préhospitalar.

Lower semicontinuity of attractors for non-autonomous dynamical systems

This paper is concerned with the lower semicontinuity of attractors for semilinear non-autonomous differential equations in Banach spaces. We require the unperturbed attractor to be given as the union of unstable manifolds of time-dependent hyperbolic solutions, generalizing previous results valid only for gradient-like systems in which the hyperbolic solutions are equilibria. The tools employed are a study of the continuity of the local unstable manifolds of the hyperbolic solutions and results on the continuity of the exponential dichotomy of the linearization around each of these solutions

Real cockpit proposal for flight simulation with airbus A32x models: an overview description

This paper describes the several steps to build an elaborate flight simulator cockpit, where the hardware is designed based on Mechatronic principles and the proposed software was developed using agile methodologies to create a Cyber-Physical System (CPS). Furthermore, this research attempts to simulate the real environment from an aircraft as close as possible with a real scale developed cockpit. Based on this, the presented paper contributions include: (1) The implementation of a complex dynamic system such as a CPS, where the Mechatronic system is part of it; (2) The deployment of a scale model of an Airbus A32x aircraft (one of the most used), integrating into a mathematical model adapted to the operation of an aircraft flight simulation system, regarding the physical forces involved. This project is also used to captivate the students’ motivation to the areas of technology such as electronics and programming and permits its development as a student project and thesis. Results allow validating the proposed cockpit.This work has been supported by FCT - Fundação para a Ciência e Tecnologia within the Project Scope: UIDB/05757/2020.info:eu-repo/semantics/publishedVersio

Nutritional and phytochemical composition of Vaccinium padifolium Sm wild berries and radical scavenging activity

Blueberries have a well-deserved reputation as a potential functional food, supported by studies which have identified and quantified various nutrients and bioactive phytochemicals with known benefits for human diet and health. Wild blueberries have attracted particular attention due to the levels and concentrations of those phytonutrients. This study aims to evaluate for the first time the chemical composition of Madeira Island's endemic Vaccinium padifolium Sm wild berry. Results show that this fruit contains high values of total soluble phenolic content (around 4 g GAE kg-1 FW), as well as significant values of total monomeric anthocyanin content (around 3 g eq. cyanidin kg-1 FW) and DPPH scavenging activity (around 86.72%). Additionally, results reveal that this fruit has water content of about 88% as well as low sugar content (17.98 and 29.73 g kg-1 for glucose and fructose, respectively). Results also confirm that this wild blueberry is a good source of dietary fiber, fat and minerals. The high level of terpenoid compounds stands out in the aroma profile analysis.Ana C.

Cost and efficiency analysis of commercial softeners in the sewability behavior of cotton fabrics

This paper reports a comparative case study on the use of different softening products for bed linen fabrics, specifically regarding the sewability of the fabrics. The market offers a wide variety of commercial formulations of softeners for this purpose, but the composition and price varies considerably. This work was aimed to assess the relationship between the cost and effectiveness of different softener formulations in home textiles finishing. Objectively, the effect of different softeners and their concentrations on sewability of the fabrics was studied. Non-ionic polyethylene dispersions and a cationic silicone softener micro-emulsion in different concentrations and combinations were considered in this investigation. It was found that a combination of silicone and polyethylene based softeners presents the most interesting cost/performance behavior.This work has been funded by FEDER through Programa Operacional Factores de Competitividade - COMPETE and by national funds by FCT - Fundacao para a Ciencia e a Tecnologia in the context of project PEst-C/CTM/UI0264/2011

Soundserver: data sonification on-demand for computational

The rapid accumulation of large collections of data has created the need for efficient and intelligent schemes for knowledge extraction and results analysis. The resulting information is typically visualized, but it may also be presented through audio techniques such as sonification. Sonification techniques become especially interesting when the client application runs on graphically limited devices such as mobile phones or PDAs (Personal Digital Assistants). In this paper we present an architecture for a sonification server that will be used in the Sound Data Mining project. In this project sound will be used to increase perception and present information extracted by spatial data mining techniques. The server is based on an audio synthesis engine and will relieve clients with little audio synthesis capabilities from the burden of sound processing. By providing sonification modules, this server can potentially be used on a variety of applications where sonification techniques are require

Of those who were not actively working (n = 82), 53.6% were retired, 45.2% were housewives, and 1.2% were unemployed. Concerning conceptions about cataract, 79.0% referred to it as "a small skin fold that gradually covers the eye" and 32.4% mentioned, in addition, other conceptions. Concerning the cause, of the alternatives presented to them, 80% reported aging, 47.1% blamed "overusing the eyes in the workplace or at home", 7.1% believed they had cataract due to some kind of "spell." Of the associated answers, 94.1% referred to "blurred vision" in people suffering from cataract, 72.4% thought the person may become blind, and 66.5% believed that the patients suffering from cataract are depressed because they cannot see. Regarding surgery, 28.8% were afraid of undergoing surgery; of those, 16.3% cited with the fear of dying during surgery, 55.1% thought they might become blind, 40.8% believed the surgery would be painful, and 8.2% followed religious practices that do not permit surgery. CONCLUSION: Some misconceptions were identified, and the fear of blindness was the most mentioned reason for not seeking cataract surgery, which indicates the need for orientation.OBJETIVO: Identificar percepções de adultos portadores de catarata em relação à doença e ao tratamento cirúrgico.
