Regular versus as-needed budesonide and formoterol combination treatment for moderate asthma: A non-inferiority, randomised, double-blind clinical tr…
2015
Summary Background Treatment guidelines for patients with moderate persistent asthma recommend regular therapy with a combination of an inhaled corticosteroid and a longacting β 2 agonist plus as-needed rapid-acting bronchodilators. We investigated whether symptom-driven budesonide and formoterol combination therapy administered as needed would be as effective as regular treatment with this combination plus as-needed symptom-driven terbutaline for patients with moderate asthma. Methods In this non-inferiority randomised clinical trial, we recruited adult patients (18–65 years of age) with stable moderate persistent asthma, according to 2006 Global Initiative for Asthma guidelines. Patients …

Impact of building automation control systems and technical building management systems on the energy performance class of residential buildings: An …
2014
Abstract The paper focuses on the evaluation of the impact on residential buildings of building automation control (BAC) and technical building management (TBM) systems. This work shows how the control, monitoring and automation functions considered by the European Standard EN 15232 can considerably influence the energy performance of a single-family test house and, consequently, its energy performance class. The study puts into evidence that the benefit that can be drawn from the installation of BAC and TBM systems depends on the type of technical appliances in the household and on the starting energy performance class. Finally, the economic impact due to the introduction of BACS or TBM fu…
ANALYSIS OF IMPACTS ON ELECTRIC POWER SYSTEM OPERATION OF LOAD MANAGEMENT IN RESIDENTIAL AND TERTIARY BUILDINGS
2012
Load management includes all the techniques, logics, actions and programs through which the electric utilities and the customers are able to manage loads absorption in a more prudent and efficient way; it determines economic benefits for the users, but also allows a network management and operation simpler and cheaper, determining technical and economic benefits. The present paper constitutes a detailed study of interventions and techniques to control demand in the residential and tertiary sectors and the effects that these actions have on the entire electrical system and its management. It discusses the implications of such control actions in terms of reduction of network losses and relate…
To Assess the Validity of the Transfer Function Method: A Neural Model for the Optimal Choice of Conduction Transfer Functions
2010
This paper presents a new mathematical approach applied to the Conduction Transfer Functions (CTFs) of a multilayered wall to predict the reliability of building simula- tions based upon them. Such a procedure can be used to develop a decision support system that identifies the best condition to calculate the best CTFs set. This is a critical point at the core of ASHRAE calculation methodology founded on the Transfer Function Method (TFM). To evaluate the perfor- mance of different CTFs sets, the authors built a large amount of data, subsequently employed to train a Neural Network Classifier (NNC) able to predict the reliability of a simulation without performing it. For this purpose all th…
The relation between workload and personal well-being among university professors
2019
The aim of the present study was to explore the level of perceived workload of university professors and to evaluate related psychosocial risks, such as addiction to work, psychological distress, and work–life conflicts. A total of 252 professors, balanced for gender (Mean age = 48.1; DS: 5.1) from 10 different universities across Europe participated in the research. Participants completed the University’s Work Environment Survey, the Dutch Workaholism Scale, and The General Health Questionnaire. The results showed that workload, when linked to bureaucratic university practices, is a predisposing factor to a negative perception of work-related well-being among university professors.
Burnout Syndrome in municipal health managers
2016
Resumo Introdução Os gestores municipais da saúde devem responder às demandas de suas equipes e dos pacientes do Sistema Único de Saúde, enfrentando cotidianamente situações potencialmente estressoras. A sobrecarga no trabalho pode levar à exaustão física e mental, com esgotamento dos recursos emocionais, e desencadear a Síndrome de Burnout (SB), cujas consequências podem atingir o serviço gerenciado, uma vez que, ao desempenhar essa atividade laboral, tomam-se decisões determinantes nas ações em saúde que afetam muitas pessoas. Este estudo verificou a presença da SB nos gestores municipais de saúde do Estado de São Paulo. Métodos Estudo do tipo transversal no qual foram coletados dados soc…
L'evolució històrica de la psicologia del treball i de les organitzacions
2010
El món organitzacional ha esdevingut l'eix vertebrador de la Psicologia del treball, des del sistema gremial al sistema fabril, que reunia les característiques de veritables organitzacions industrials. Les notes que caracteritzen el procés són: la mentalitat racional, la mecanització de la fabricació i la utilització del vapor com nova energia aplicable a la indústria. A més, la mecanització tindria efectes sobre l'organització del treball, en l'extremar la diferenciació de funcions i la divisió de tasques. Taylor, des de l'enginyeria, introduí una organització científica del treball per millorar els sistemes i els llocs laborals. Amb el mateix objectiu, orientat a millorar l'administració …
A demand-based methodology for planning the bus network of a small or medium town.
2010
This work aims at developing a demand-based methodology for designing the bus network of a small or medium town. The proposed modelling tool adopts a multi-agent objective function which evaluates performance in the context of different stakeholders: the surplus of travellers (car and bus users); the bus service provider’s revenues and operation costs. This approach was applied to an existing bus network, serving city of Trapani, which is a medium town in the south of Italy (Sicily), with 100000 inhabitants. The bus-based public transport system attracts only about 5% of commuter trips within Trapani (source: National Institute of Statistics, 2005). This paper reports on an analysis of the …
Influence of ANN parameters on the performance of a refined procedure to solve the load-flow problem
1999
In recent years, interest in the application of Artificial Neural Networks (ANN) to electrical power systems has grown rapidly. In particular the use of ANN in the solution of the load-flow problem in wide electrical networks is an interesting research topic, because it constitutes a good alternative to the classical numerical algorithms. In this paper a refined solution strategy based on statistical methods, on a particular Grouping Genetic Algorithm (GGA) and on Progressive Learning Network (PLN) is presented. Tests on the solution of load-flow equations of the standard IEEE 118 bus network confirm the good potential of this approach; in particular the search for optimal values of the PLN…
