Abstract: Access control models describe frameworks that dictate how subjects (e.g. users) access resources. In the Role-Based Access Control (RBAC) model access to resources is based on the role the user holds within the organization. RBAC is a rigid model where access control decisions have only two output options: Grant or Deny. Break The Glass (BTG) policies on the other hand are flexible and allow users to break or override the access controls in a controlled and justifiable manner. The main objective of this paper is to integrate BTG within the NEST/ANSI RBAC model in a transparent and secure way so that it can be adopted generically in any domain where unanticipated or emergency situations may occur. The new proposed model, called BTG-RBAC, provides a third decision option BTG, which grants authorized users permission to break the glass rather than be denied access. This can easily be implemented in any application without major changes to either the application code or the RBAC authorization infrastructure, apart from the decision engine. Finally, in order to validate the model, we discuss how the BTG-RBAC model is being introduced within a Portuguese healthcare institution where the legislation requires that genetic information must be accessed by a restricted group of healthcare professionals. These professionals, advised by the ethical committee, have required and asked for the implementation of the BTG concept in order to comply with the said legislation.2009-01-01T00:00:00ZWho should access electronic patient recordshttps://hdl.handle.net/10216/917282023-05-24T06:30:00Z2008-01-01T00:00:00ZTitle: Who should access electronic patient records
Abstract: Access control to Electronic Patient Records (EPR) may greatly depend on users' objectives and needs. The purpose of this study is to assess the opinions of medical doctors within a university hospital towards access control to an EPR. We selected a randomized sample of 58 doctors from a university hospital and 45 structured interviews were applied. 42 respondents (93%) agree with the existence of access control levels to patient information according to healthcare professionals' category and 31 (69%) think that more sensitive information (e.g. HIV) should be accessed only by doctors that treat those patients. As 24 doctors (53%) feel that there is no need for them to see all information about all the patients, 41 (91%) think that nurses should not be able to do it also. Further, 31 doctors (69%) believe that patients themselves should not access their full medical record. These results show that it is very hard to get to a consensual policy regarding access control to. EPR by its regular users. There is therefore the need for a multidisciplinary agreement that can include healthcare professionals' experiences and needs in order to define the most appropriate and efficient way to perform access control to the EPR.2008-01-01T00:00:00ZDiagnosis of Musculoskeletal Disorders in Manufacturing Workershttps://hdl.handle.net/10216/1481652023-03-02T07:17:04Z2013-01-01T00:00:00ZTitle: Diagnosis of Musculoskeletal Disorders in Manufacturing Workers
Abstract: The Musculoskeletal disorders are a heterogeneous group of diseases that include peripheral nerve compressions, muscular and vascular disorders, tendinitis and tenosynovitis. Tend to be referred to as being related directly or indirectly with the work. It is intended with this article to contribute to clarify this relationship. Are provided clues stemming from results of three evaluations by three different methods done independently, but coordinated, by three teams, to the same group of workers. The study had as targeted a factory with 620 workers, 166 of whom work in the studied production sector. The sample consisted of 109 individuals which have been assessed by three different methods (nordic inquiry, medical examination and RULA). From this evaluation was diagnosed DME in workers that didn't present symptoms. This strand unexpected and not habitually addressed needs further studies.

Abstract: This work aims at 3D model reconstruction and hemodynamic analysis of carotid bifurcations based on hospital ultrasound images. The suggested approach addresses B mode image segmentation as a pattern recognition problem and boundary velocity conditions are extracted from Doppler PW mode velocity data. Both tasks are solved using a combination of artificial neural network (ANN) tools. The development of an integrated technique for geometric reconstruction, structured meshing, blood flow simulation and hemodynamic analysis of the carotid bifurcation enables the quantification of the degree of stenosis and promotes the understanding of how hemodynamic factors are involved in atherosclerotic disease.2015-01-01T00:00:00ZHeart Rate Variability during Plateau Waves of Intracranial Pressure: a pilot descriptive studyhttps://hdl.handle.net/10216/1023902022-10-15T14:00:28Z2015-01-01T00:00:00ZTitle: Heart Rate Variability during Plateau Waves of Intracranial Pressure: a pilot descriptive study
Abstract: This study aims to describe heart rate variability during the first episode of plateau waves of intracranial pressure (ICP) in Traumatic Brain Injury (TBI) in order to characterize and identify at bedside this cerebrovascular phenomenon. The general behavior of the heart rate variability (HRV) spectral measures expressed in the medians across patients is concordant with an increased HRV in the latter part of the baseline and plateau wave, followed by a decrease after the event and a new increase during the recovery. In low and high frequency bands the same increase is more marked in the parametric analysis. Interpretation of HRV may help clinicians to better identify the plateau waves and allow earlier management.2015-01-01T00:00:00ZTeste / Reteste do questionário Nordico numa indústria alimentarhttps://hdl.handle.net/10216/1241192022-10-15T13:52:00Z2014-01-01T00:00:00ZTitle: Teste / Reteste do questionário Nordico numa indústria alimentar2014-01-01T00:00:00ZReconstructing Stenotic Carotid Models from Ultrasound Imageshttps://hdl.handle.net/10216/957632022-10-13T20:34:12Z2015-01-01T00:00:00ZTitle: Reconstructing Stenotic Carotid Models from Ultrasound Images

Abstract: Acquired Brain Injury (ABI) is one of the leading causes of individuals' reduced participation in various contexts of life, compromising autonomous functioning and performance in complex activities. Neurocognitive rehabilitation, carried out by transdisciplinary teams, is part of the intervention after the acute phase, aiming patients' maximum functionality and quality of life. Serious games and virtual reality begin to provide innovative solutions in this area. In this study, a prototype platform for the rehabilitation of executive functioning and other related cognitive functions is presented: the Virtual City. Part of a larger project, it consists of urban virtual environments that simulate real-life scenarios and activities. Tests will be performed to validate it as a tool for the rehabilitation of ABI.2012-01-01T00:00:00ZNew Challenges in the Higher education area: university networks for internationalization and globalization.https://hdl.handle.net/10216/238192022-10-16T19:02:50Z2009-01-01T00:00:00ZTitle: New Challenges in the Higher education area: university networks for internationalization and globalization.
Abstract: The "A NAME for Health" project, funded by the EDULINK program, is a project that establishes A Network Approach in Medical Education (NAME) for the Pursuit of Quality in Higher Education Institutions (HEIs) and Health Systems. It aims to improve Health Care through an ongoing intervention quality program on Medical Education, at 4 HEIs in Portugal, Angola and Mozambique: Faculty of Medicine of University of Porto (project coordinator), Portugal; Faculty of Medicine of Agostinho Neto University, Luanda, Angola; Faculty of Medicine of Eduardo Mondlane University, Maputo, Mozambique; and Faculty of Health Sciences of Lúrio University, Nampula, Mozambique. São João Hospital, E.P.E. and Calouste Gulbenkian Foundation are associated with this Project.
Specifically, this Higher Education project aims at reinforcing the Partner Institutions' ability to improve academic skills and clinical specializations in three priority areas (Paediatrics, Gynaecology & Obstetrics and Infectious Diseases) related with the Millennium Development Goals. The presence of a qualified network for Medical Education helps to elevate the overall level of medical care available to the people of Angola and Mozambique, through academic stimulation. The network's priority is to reinforce the capabilities and the existing strengths of the Higher Education sector, through the creation of a more qualified staff and supporting an efficient development of these HEIs.
With these objectives in mind, three types of activities are being developed: structuring, academic and clinical activities. Structuring activities include the establishment of Centers for Medical Education, creation of a Network Technological Platform to the different HEI (e-learning and long-distance learning), and the establishment of Students Support Office; academic activities consist of an analysis of the medical curriculum, its reform, implementation and monitoring, and IT Seminar/Conference; clinical activities comprise the establishment of a mobility program for clinical teachers and physicians.
The project's strength and sustainability come from the belief that improvements in the whole Health System will be attained through the improvement of clinical and academic practice.
Increasing the Institutions' scientific, pedagogical and clinical levels will enhance the network of Portuguese speaking countries, strengthening the link between Medical Education Healthcare in the African Higher Education Institutions.
Sustainability will also be reinforced through the Technological Platform (which will be maintained among the Institutions) since it will enhance the investments that are being done in the partner Universities' information and communication technologies.
Curricular reforms and their adaptation to international standards, together with the expected multiplier effects obtained through the clinical mobility program, will also be a way of supporting academic and clinical sustainability after the conclusion of the project.
The competence acquisitions in the three priority clinical areas will also have a multiplier effect at the level of knowledge transfer to the other health agents such as nurses and health community agents. Focusing on Medical Education by structuring its organization, will generate involvement of young medical students, which will be the future physicians and clinical teachers (The Project A NAME for Health is supported by EDULINK Program, Contract nr. 9 ACP RPR 118 # 29)2009-01-01T00:00:00ZWall shear stress description in patient-specific right coronary arteries with stenosis - CFDhttps://hdl.handle.net/10216/1252612022-10-15T13:41:48Z2019-01-01T00:00:00ZTitle: Wall shear stress description in patient-specific right coronary arteries with stenosis - CFD
Abstract: The present work shows the relative residence time spatial distribution, the strongest metric of hemodynamic descriptors for assessing atherosclerotic plaque formation, for completely different patient cases: different geometry configuration, different percentage of lumen stenosis and different locations of the stenosis. The stenosis tends to increase, even more, when located between two side-branch bifurcations. Moreover, locations with high roughness have a high tendency to atherosclerosis appearance.2019-01-01T00:00:00Z
