Problemática do tratamento dos efluentes vinícolas
[Excerto] As operações relativas a vinificação necessitam de numerosas lavagens, produzindo uma poluição essencialmente de origem orgânica. O caracter sazonal dos efluentes rejeitados, a sua grande variabilidade no tempo e de adega para adega, conduz por vezes a uma avaliação defeituosa da sua carga poluente. Surgindo maioritariamente na época estival, esta poluição pode deteriorar gravemente os meios receptores. Na realidade e principalmente o efeito da concentração nas épocas de ponta da actividade, que conduz aos problemas mais graves de mortalidade da fauna piscícola, por efeito de asfixia. A sub-estimativa da carga poluente das adegas em períodos de vindima e de trasfega traduz-se frequentemente por perturbações no funcionamento das estações de tratamento de águas residuais municipais as quais, em geral, estão ligadas.

Equity in access to MRI equipment: the Portuguese case
Magnetic resonance imaging (MRI) is a method of image diagnose proven to be of undeniable importance when it comes to neuro and cardio related diseases. In fact, these diseases (such as: ischemic heart disease, stroke and acute myocardial infection) have high incidence in Portugal. For these reasons, the allocation of this medical technology should not be considered with light thoughts. In fact, making decision of resource allocation in health care can be a very complex and contested matter. The impacts of new technology allocation, such MRI, can be assessed in a variety of ways. However, a fundamental component should always be present: the use of evidence-based decision-making methods. One of these methods is Technology Assessment (TA). This paper aims to characterize the equity on access of the Portuguese population in general, to a specific medical device such as MRI, under the TA point of view. It is hoped to promote a bridge of scientific knowledge between the gap on research and policy-making through TA that can emerge as a tool to aid decision-makers in the organization of health systems. There are gaps in providing healthcare, due to geographical imbalances, with some areas unable to provide certain specialized services, as hospitals in the countryside do not provide all medical specialties. Portugal has also a large independent private sector that provides diagnostic and therapeutic services to NHS users under contracts called conventions. These medical contracts cover ambulatory health facilities for laboratory tests and examinations such as diagnostic tests and Radiology. However, there is no convention from the NHS when concerning the MRI exam. Therefore, this reality can be considered a limitation in the access of the general population to this kind of clinical exam. TA can play an useful and important role in helping the decision-makers to explore potential gains that might be achieved by introducing a more rational decision making into health care management, namely into the Radiology area, regarding the allocation of MRI equipment.Orientadores: António Brandão Moniz (FCT-UNL) e Michael Decker (ITAS-KIT
Decision-making process in radiology: the magnetic resonance example in the TA context
Based on the report for “Project IV” unit of the PhD programme on Technology Assessment (Doctoral Conference) at Universidade Nova de Lisboa (December 2011). This thesis research has the supervision of António Moniz (FCT-UNL and ITAS-KIT) and Michael Decker (Karlsruhe Institute of Technology-ITAS). Other members of the thesis committee are Carlos Alberto da Silva (University of Évora), José Maria de Albuquerque (Institute of Welding and Quality), Lotte Steuten (University of Twente), Mário Forjaz Secca (FCT-UNL) and Nelson Chibeles Martins (FCT-UNL).In order to understand the decision-making process in a Radiology Department, taking the Magnetic Resonance Equipment as an example, this paper reports a project to be followed. It is a guideline for future work development regarding Technology Assessment in Radiology. The Theoretical Framework is divided is three big issues. The first is “Technology Assessment”. Starting with the definition of some important concepts, the history and development of Technology Assessment will be addressed. The aim of this issue is to give a general main idea concerning TA contextualization. Doing a transposition of this subject to health area, it is also important to understand the particularities of Health Technology Assessment, second issue. Portugal framework on this subject will also be addressed. As so, the Portuguese National Health System is characterized and the decision-making stakeholders identified, has well as the competences for the decision-making process in general. The third issue is Decision-Making and its aim is to give a general elucidation on decision-making matters. To accomplish this, a research methodology was outlined, so that six research questions could be answered and five hypotheses could be accepted or refuted, in the future. With this research methodology, the Portuguese state of the art Magnetic Resonance equipment existence will be studied, using a survey as a resource. In the future, a mapping stakeholder technique will be used to identify the decision making key stakeholders and a survey will be applied to map theirs skills and competences in the process, where a pre-test was already applied. The results of this pre-test are presented
Technology governance in radiology: the example of magnetic resonance imaging
Based on the report for the unit “Project III” of the PhD programme on Technology Assessment in 2011. The unit was supervised by Prof. António B. Moniz (FCT-UNL).This report aims to be the gathering of the main ideas that culminated in the presentation at the 1st Winter School of the PhD Programme on Technology Assessment (FCT-UNL) in December 2010. It is a guideline for future work development regarding Technology Assessment in Radiology, particularly having Magnetic Resonance Imaging, as an example. Therefore, as a background, it is necessary to understand what is “Technology Assessment”, how it developed and what it Europe’s interest in this area.
Doing a transposition of this subject to health area, it is also important to understand the particularities of Health Technology Assessment. Portugal framework on this subject will also be addressed. As so, the Portuguese National Health System is characterized and the decision-making stakeholders identified, has well as the competences for the decision-making process in general.
More generally, the different stakeholders perception involved in decision making, the mapping skills on technology assessment and decision making, the identification of indicators present in this decision making in Radiology, particularly in Magnetic Resonance area, are subjects to be addressed. To accomplish this, a research methodology was outlined, so that six research questions could be answered and five hypotheses could be accepted or refuted, in the future. With this research methodology, the Portuguese state of the art Magnetic Resonance equipment existence will be studied, using a survey as a resource.
In the future, a mapping stakeholder technique will be used to identify the decision making key stakeholders and a survey will be applied to map theirs skills and competences in the process, where a pre-test was already applied
MARCOS REGULATÓRIO DA EDUCAÇÃO A DISTÂNCIA NO BRASIL: GOVERNO DE FERNANDO HENRIQUE CARDOSO (1995-2002)
Objetiva analisar a política e os marcos regulatório da educação a distância no Brasil, buscando estabelecer os nexos teóricos e práticos nas dimensões políticas e na regulamentação da agenda legislativa brasileira, no governo de Fernando Henrique Cardoso (1995-2002). Aponta como o Estado brasileiro só passou a regular efetivamente a Educação a Distância (EaD) em 1996, com a aprovação da nova Lei de Diretrizes e Bases (LDB) em 1996, e posteriormente, várias regulamentações foram feitas por meio de Decretos, Portarias e Resoluções. Mostra como as políticas educacionais e a abertura jurídica propiciada pela nova LDB/96, a modalidade em EaD passou a ser estruturada e ofertada mais intensamente no contexto da política de formação de professores e na expansão da educação superior brasileira
