A partir de um alerta internacional emitido pelas autoridades sanitárias francesas no ano de 2010 com respeito a altas taxas de ruptura de implantes mamários da marca Poly Implant Prothèse (PIP), a Agência de Vigilância Sanitária brasileira (ANVISA) suspendeu a importação, distribuição, comércio e uso destes implantes no país. Visando manter a qualidade destes produtos no mercado brasileiro, a partir de março de 2012 – conforme publicado pelo Instituto Nacional de Metrologia (INMETRO) – foi instituída a certificação compulsória dos implantes mamários e em seguida definidos os ensaios através dos quais os implantes mamários devem ter sua conformidade avaliada, sendo esses ensaios mecânicos e químicos. Este trabalho apresenta o desenvolvimento de equipamentos e metodologia para avaliação da conformidade de dois ensaios mecânicos em implantes mamários: ensaio de fadiga e ensaio de resistência ao impacto. Duas normas foram utilizadas para o processo de acreditação: ISO 14607 – Non - active surgical implants – Mammary implants – Particular Requirements, e ABNT NBR ISO 14607 – Implantes cirúrgicos não ativos – Implantes mamários – Requisitos particulares. Os equipamentos utilizados foram desenvolvidos e construídos ao longo do desenvolvimento deste estudo e os testes foram realizados em implantes mamários da marca PIP obtidos junto a ANVISA. A primeira etapa consistiu em organizar os documentos necessários para acreditação junto ao INMETRO e, após, ensaios os ensaios foram realizados. Ao todo trinta e cinco implantes foram ensaiados – 31 na primeira parte do trabalho e 04 na segunda – e analisados em lupa para verificação de defeitos causados pelos testes como: fraturas, cortes, alteração de forma, entre outros. Os equipamentos e metodologia desenvolvida atendem os requisitos de ambas as normas e permitem avaliação de conformidade de próteses mamárias comercializadas no país, no que diz respeito ao ensaio de fadiga e resistência ao impacto. / Due an international alert issued by French authorities in 2010 regarding high rupture rate of breast implants related to Poly Implant Prothèse (PIP), the Brazilian Health Surveillance Agency has suspended the importation, distribution, commercialization and use of these implants into Brazil. In order to maintain the quality of these products in Brazilian market, on March 2012 – according published by National Institute of Metrology – it has been decided for compulsory certification of breast implants and then defined the tests through which these products have to be submitted for its conformity assessment, being these mechanical and chemical tests. This dissertation evaluates the development and methodology for conformity assessment of two mechanical tests on breast implants: fatigue and impact resistance test. The process was based on two standards: ISO 14607 and ABNT NBR ISO – Non - active surgical implants – Mammary implants – Particular Requirements. The equipment used was developed in the laboratory during the realization of this study and the tests were performed on implants produced by PIP provided by National Sanitary Surveillance Agency. It started with the organization of the documents to be sent to National Institute of Metrology, in order to ask the accreditation and then tests were performed. Thirty five implants were tested – 31 on first part of the work and 04 on the second one – and then analyzed to detect any anomaly that could be considered a defect such as: rupture, cuts, shape alteration, etc. The equipment and methodology has met the requirements from both standards and enable conformity assessment of breast implants commercialized in Brazil, regarding to fatigue and impact resistance tests.

O processo de liberação da operação comercial de um túnel rodoviário, sempre é realizada sobre a pressão típica do final de um cronograma, cujo prazo final, está em vias de se esgotar. Por outro lado considerando os relevantes riscos envolvidos com a operação de um túnel, o órgão público que libera o início da operação comercial (Artesp no caso do Estado de São Paulo), deve ter plena certeza que a nova estrutura está pronta a utilização e apresenta-se totalmente preparada a atender os requisitos mínimos de segurança. O presente trabalho propõe uma metodologia de avaliação de conformidade aderente a NBR ISO/IEC 17020:2006 - avaliação de conformidade com os critérios gerais para o funcionamento de diferentes tipos de organismos que executam inspeções. Para tanto foi realizado um extenso e minucioso trabalho de identificação dos requisitos aplicáveis, concatenando as referências internacionais de túneis, o modus operandi nacional e a ferramenta gerenciamento de riscos, que resultaram numa proposta de metodologia de avaliação de conformidade composta por onze atividades, que aplicadas permitem avaliar as condições de liberação ao uso e operação comercial de túneis rodoviários. / The process of releasing the commercial operation of a road tunnel is always done under the typical pressure of a chronogram deadline. On the other hand, considering the relevant risks involved with the tunnel operation, the public institution that releases the beginning of the commercial operation (ARTESP, in the case of São Paulo State), should be totally sure that the new structure is ready to be used and shows it is completely prepared to meet the needs of the minimum security requirements. The present work proposes an evaluation methodology of adherent conformity the NBR ISO/IEC 17020:2006 Conformity evaluation with the general criteria for the functioning of different types of organisms that perform inspections. In order to do so, a large and detailed work of identification of the applicable requirements, linking together the international references of tunnels, national way of working and the tool Management of Risks, that ended in a proposal of conformity evaluation methodology composed by eleven activities, that if applied, allow evaluation of the releasing conditions to the use and commercial operation of road tunnels.

In doing so, it aimed to identify risks, deal with major non-conformities and contribute to improving the correction of non-conformities, the mechanisms of conformity assessment and the SISORG (Brazilian System of Organic Conformity Assessment). The analyses were based on customers? certification processes (documents) and their organic conformity assessment, audit certification requests and customers? opinion as articulated in their responses to a questionnaire. The process analysis pointed to non-conformities in 7 out of the 8 conformity sections, while the request analysis pointed to non-conformities and inconsistencies in all sections, with enforcement of 20%. In both analyses of the Office, the highest incidence of non-conformities related to document Organic Management Plan Booklet. Similarly, customers assessed that the Management Plan Booklet provided by the Ministry of Agriculture is flawed as to the requirements of current legislation. Customers also assessed that the bottlenecks for organic production are related to the construction and structuring of the Brazilian organic agriculture. In conclusion, the Organic Management Plan Booklet does not meet the legislation; the SISORG-oriented organic production requires skilled labor; and the requirements set forth in the regulations for organic agriculture do not have the same dynamics as in the productive practice. / O trabalho teve como objetivo analisar criticamente processos de certifica??o da agricultura org?nica no Brasil, com foco no estado de Minas Gerais, mais especificamente na certificadora p?blica, o Organismo de Avalia??o da Conformidade Instituto Mineiro de Agropecu?ria ? IMA e em seus clientes (produtores org?nicos que solicitaram a certifica??o org?nica e posteriormente cadastrados no MAPA) no intuito de identificar os riscos e tratar as principais n?o conformidades e contribuir para a melhoria da corre??o das n?o conformidades, e dos mecanismos de avalia??es da conformidade e do SISORG. As an?lises se basearam nos processos de certifica??o (documentos) dos clientes e suas avalia??es da conformidade org?nica, na documenta??o de requisi??o ao processo de certifica??o por auditoria e na an?lise pela ?tica do cliente, por question?rio, destas mesmas fases do processo de avalia??o da conformidade org?nica pela Certifica??o por auditoria. A an?lise dos processos apresentou n?o conformidades em 7 das 8 sess?es de verifica??o, a an?lise da documenta??o de requisi??o ao processo de certifica??o apresentou n?o conformidades, inconsist?ncias em todas as sess?es de verifica??o, com efetiva??o dos processos de apenas 20%. Em ambas as an?lises pelo OAC, a maior incid?ncia de n?o conformidades se relacionam ao documento Caderno de Plano de Manejo Org?nico. Da mesma forma na avalia??o pelos clientes, estes apontam que o Caderno de Plano de Manejo disposto pelo Minist?rio da Agricultura ? falho quanto ?s exig?ncias da legisla??o vigente. A an?lise pelo cliente dos gargalos para a produ??o org?nica, relacionam principalmente com a constru??o e estrutura??o da agricultura org?nica brasileira. Diante dos dados obtidos, ? poss?vel concluir que a publica??o caderno plano de manejo disposto pelo Minist?rio da Agricultura, n?o atende a legisla??o a que se relaciona; a produ??o org?nica de acordo com as normas do SISORG demandam m?o de obra especializada; e as exig?ncias dispostas nos normativos da agricultura org?nica n?o t?m a mesma din?mica da pr?tica produtiva.

No. of bitstreams: 1 2016 - Mariano Gomes.pdf: 1567671 bytes, checksum: afce58d63dd5811f4cc58b360d326898 (MD5) Previous issue date: 2016-07-11 / CNPq / The regulation of organic production in Brazil was built in a participatory manner, and is updated periodically by members of organized civil society and public agencies. Brazil recognizes three mechanisms for assessing organic compliance: certifier-operated certification, participatory compliance systems operated by participatory conformity assessment organizations (OPACs) and social control organizations operated by organized family farmers who are exempted from certification to sell directly to consumers. The objective of this legal framework was to represent the various realities of agroecology and organic production in the country. This study aims to investigate the case of public certification in organic agriculture in Brazil, focusing on the State of Minas Gerias, more specifically on Instituto Mineiro de Agropecu?ria (IMA), a Conformity Assessment Agency. As of 2011, producers and conformity assessment agencies must be registered with the Ministry of Agriculture. The analysis of the National Record of Organic Producers (CNPO) in the last four years showed a marked increase in the number of organic producers registered (96%). The distribution of the organic producers in the CNPO according to the three mechanisms proposed in the regulation points to different forms of ensuring organic quality in the country, which follow the regulation despite applying different tools and using different trade spaces. The growth in the number of OPACs operating Participatory Assurance Systems in this period (2012-2016) was over 200%. Certification, albeit not regulated, is the mechanism chosen worldwide to provide organic quality assurance, as implemented primarily by private companies. Public certification takes place only in Denmark, although in some European countries it is subsidized for small producers for a certain period of time. In Brazil, federal resources offered by the Brazilian Support Service for Micro and Small Business (SEBRAE), in partnership with the National Institute of Metrology, Quality and Technology (INMETRO), supported the implementation of public and private certification (SCOFANO, 2014) after publication of the legal framework for organic agriculture (2003-2009). At the federal states level, public certification exists in the states of Paran? through Instituto de Tecnologia do Paran? (TECPAR) and of Minas Gerais through IMA. At the national level, the service is provided by Instituto Nacional de Tecnologia, located in Rio de Janeiro. Producers linked to public certification represent 2.22% of the registrations in the CNPO. Because they are public bodies, they can effectively comply with the principle of independence established by the ISO certification standard. The partnership with the public ATER Organizations is strategic, and should be pursued by public certifiers for the development of the sector. For the analysis of the organization, we rely on the four-fold view of organizations according to the anthroposophy and teachings of Rudolf Steiner. In the resource dimension, IMA needs to improve its fleet and electronic equipment, continue to support the professional qualification of its staff, and also broaden its staff. In the process dimension, it is efficient. However, it should invest in the relationship dimension, integrating its employees and partner organizations. In the identity dimension, actions that favor valuation and reaffirm the mission and values of both employees and the company should be sought, evaluated and renewed periodically. / A regulamenta??o da produ??o org?nica no Brasil foi constru?da de forma participativa, e ? atualizada periodicamente por membros da sociedade civil organizada e ?rg?os p?blicos. O Brasil reconhece tr?s mecanismos de avalia??o da conformidade org?nica: certifica??o operada pelas certificadoras, sistemas participativos de garantia - SPG operados pelas organiza??es participativas de avalia??o da conformidade (OPAC) e as organiza??es de controle social (OCS), operacionalizadas pelos agricultores familiares organizados que realizam a venda direta aos consumidores, sendo isentos de certifica??o. O objetivo deste arcabou?o legal era representar as diversas realidades envolvidas com a agroecologia e a produ??o org?nica no pa?s. O trabalho teve como objetivo o estudo de caso da certifica??o publica na agricultura org?nica no Brasil, com foco no Estado de Minas Gerias, mais especificamente no Organismo de Avalia??o da Conformidade (OAC), Instituto Mineiro de Agropecu?ria (IMA). A partir de 2011 os produtores e organismos de avalia??o da conformidade tinham que estar registrados no Minist?rio da Agricultura, Pecu?ria e do Abastecimento (MAPA). A an?lise do Cadastro Nacional de Produtores Org?nicos (CNPO), nos ?ltimos quatros anos evidenciou um crescimento acentuado no n?mero de produtores org?nicos cadastrados (96 %). A distribui??o dos produtores org?nicos no CNPO pelos tr?s mecanismos propostos na regulamenta??o mostra a realidade de diferentes situa??es existentes no pa?s para garantir as qualidades org?nicas, que embora usem diferentes ferramentas e espa?os de comercializa??o, seguem a regulamenta??o. O crescimento no n?mero de OPACs que operam SPG, nesse per?odo (2012-2016) foi superior a 200%. A certifica??o ? o mecanismo escolhido, mas n?o ? regulamentado, no mundo para dar garantia da qualidade org?nica, executada prioritariamente por empresas privadas. A certifica??o p?blica acontece somente na Dinamarca, embora em alguns pa?ses da Europa seja subsidiada para pequenos produtores, por determinado espa?o de tempo. No Brasil, recursos federais ofertados pelo Servi?o Brasileiro de Apoio as Micro e Pequenas Empresas (SEBRAE) em parceria com o Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO), ap?s publica??o do marco legal da agricultura org?nica (2003- 2009), apoiaram a implanta??o da certifica??o p?blica e privada (SCOFANO, 2014). A certifica??o p?blica estadual existe nos estados do Paran? atrav?s do Instituto de Tecnologia do Paran? (TECPAR) e Minas Gerais atrav?s do IMA, e no ?mbito federal ? ofertada pelo Instituto Nacional de Tecnologia (INT), localizado no Rio de Janeiro. Os produtores vinculados ? certifica??o p?blica, representam 2,22% dos registros no CNPO, e pelo fato de serem ?rg?os p?blicos, podem efetivamente cumprir com o princ?pio da independ?ncia estabelecido pela norma ISO para a certifica??o. A parceria com as organiza??es de ATER p?blica ? estrat?gica, e, deve ser perseguida pelas certificadoras p?blicas para desenvolvimento do setor. Para an?lise da organiza??o, nos baseamos na vis?o quadrimembrada das organiza??es de acordo com a antroposofia e ensinamentos de Rudolf Steiner. O IMA como organiza??o no n?vel dos recursos precisa melhorar a frota e equipamentos eletr?nicos, continuar com o apoio a qualifica??o profissional do seu quadro, mas tamb?m realizar concursos para ampliar sua capacidade de atua??o. No n?vel dos processos, ? eficiente. Deve investir mais no n?vel das rela??es de seus funcion?rios e com as organiza??es parceiras, na busca de maior integra??o. No n?vel da identidade, a??es que favore?am a valora??o e reafirmem a miss?o e os valores dos funcion?rios e da empresa devem ser buscados, avaliados e renovados periodicamente.

The issue of launching medical devices on the market became more intense in the last few decades in connection to the expansion of the pharmaceutical industry and legal area. This legal area is still mostly undescribed and it stands in the shadow of known and more discussed medical products. Proper legal theoretical analysis is often completely absent. This master thesis aims to complexly describe and analyse theoretical bases of current legislative regulating the launching of the medical devices on the market, including other processes related to this issue. Emphasis is places on the concept of medical device, the responsibility of the manufacturer and the nature of notified body. The author focuses on the subsequent conformity assessment process and process of registration. The process of notification and exemption from this obligation and administrative nature of selected documents. The thesis is divided into eleven chapters and the introductory chapter focuses on a general introduction to the field of pharmaceutical law, namely the regulation of medical devices, including the definition of basic questions in the work under study. The second chapter deals with the analysis of sources of legal regulation of medical devices. The chapter is divided into sources of the law of the Czech Republic and...

La protection des droits des consommateurs est un sujet essentiel visant à établir un équilibre entre tous les acteurs bénéficiant de l'élargissement du marché sans frontières. Au moment où la coopération sur la protection du consommateur entre les pays membres de l'ASEAN est établie, les réflexions comparatives sur les mécanismes internes pour protéger les intérêts des consommateurs acquéreurs des biens dans ces pays s'avèrent être un sujet nécessaire pour une meilleure compréhension des mécanismes législatifs adoptés et des situations actuelles. Ceux-ci sont donc des facteurs importants pour le développement de la protection des consommateurs.Cette étude consiste à se pencher sur les mécanismes législatifs internes applicables dans les trois pays sélectionnés tels que la Malaisie, Singapour et la Thaïlande, tendant à protéger les intérêts économiques des consommateurs vis-à-vis du problème de la non-conformité du bien à l'attente légitime. Bien que ces trois pays sélectionnés soient très différents sur la forme de l'Etat et sur le système juridique applicable, ils ont partagé un point commun ; l'intégration du concept de la protection des intérêts de consommateurs dans leurs droits depuis plus de dix ans. Nos réflexions comparatives sur les mécanismes nationaux des trois pays et sur les mécanismes régionaux de l'UE exposeront la similarité et la disparité des droits des trois pays et, ainsi, proposeront une solution pour réduire ces divergences. / Protecting the rights of consumers is a key issue to achieve the balance between all stakeholders benefiting from expanding market without borders. Currently, cooperation on the issue among the ASEAN member countries has been established; however, a further and analytical study on the topic is needed. A comparative reflection on states' internal mechanism of the protection of interests of consumers who possess goods will provide an insightful knowledge of current situation both in terms of legal instruments and facts. These are important factors for the development of consumer protection.This study is to analyse the internal legal systems applicable to the three selected countries which are Malaysia , Singapore and Thailand , aiming at protecting consumers' economic interests against the problem of non -conformity of goods to legitimate expectation. Although the three selected countries differ from each other in terms of the form of government and legal system, they share one thing in common; integrating the concept of protecting the interests of consumers in their law for over ten years. Our comparative reflections on the three countries' mechanisms, the regional mechanisms and the EU mechanisms exhibit similarity and disparity of law between the three countries and thus propose a solution to reduce these differences.

Malgré les avancées considérables dans l’analyse des preuves matérielles, et le développement ces dernières années de la police scientifique, les témoignages oculaires occupent encore aujourd’hui un rôle primordial dans les décisions de justice. Et pourtant, ces témoignages sont faillibles. En effet, de nombreux facteurs se trouvant au croisement de processus mnésiques et/ou cognitifs et de processus sociaux et/ou sociocognitifs, peuvent les impacter de façon irréversible. C’est dans ce contexte, et dans le but de mieux comprendre certaines variables à l’origine de leur fragilité, que nous avons réalisé les sept expérimentations présentées dans cette thèse.De façon plus précise, les trois premières études s’intéressaient à une technique d’audition efficace, appelée l’entretien cognitif. Notre objectif était alors de développer et d’évaluer, en laboratoire et sur le terrain, un protocole modifié d’entretien cognitif fondé sur le principe de multiplication des rappels libres. Toutefois, dans cette thèse, nous souhaitions adopter une approche plus dynamique et situationnelle de l’entretien cognitif que celle rencontrée jusqu’à présent dans la littérature. C’est pourquoi, dans une seconde partie, nous avons examiné l’efficacité de ce protocole en lien avec trois variables évaluatrices indissociables des situations d’auditions, et pouvant dans les faits impacter fortement et négativement la qualité des témoignages oculaires. Ces trois variables sont: (a) les scripts que partagent les individus à propos des évènements criminels, (b) les discussions entre témoins, et, (c) les stéréotypes associés aux témoins par le biais de leursappartenances groupales.Plusieurs résultats ont alors été montrés. Tout d’abord, nous avons confirmé l’efficacité d’une version modifiée d’entretien cognitif (ECM). Plus précisément, un protocole composé de deux rappels libres, incluant les consignes d’exhaustivité et de remise en contexte ainsi qu’une nouvelle technique destinée à favoriser le souvenir, la focalisation périphérique guidée, a permis d’améliorer, dans toutes nos études, la richesse du rappel des participants sans nuire à son exactitude. Son efficacité a d’ailleurs été montrée aussi bien en laboratoire que sur le terrain. De plus, ce protocole intègre les consignes cognitives les plus efficaces et omet les moins effectives. Parallèlement, nous avons confirmé l’impact néfaste des scripts et des discussions entre témoins sur les témoignages oculaires. Certains effets des stéréotypes liés à l’appartenance groupale du témoin ont aussi été suggérés. Enfin, concernant l’efficacité de l’entretien cognitif, et plus précisément de la versionmodifiée, certains effets délétères de ce protocole et des consignes qui le composent ont été observés en lien avec les trois variables évaluatrices considérées. Toutefois, plusieurs bénéfices intéressants ont également été révélés dans ce cadre.Ces résultats seront discutés au regard des données disponibles dans la littérature à ce jour. Des recommandations appliquées seront également émises. / Despite many advances in analyzing physical evidence, and the development these past years of the forensic police, eyewitnesses’ testimonies remains decisive in the decisions of justice. Nevertheless, these testimonies are fallible. Numerous factors, at the crossroad of memory and/or cognitive processes and of social and/or sociocognitive processes, can impact them in an irreversible manner. In this context, we realized the seven experimentations presented in this dissertation. The aim was to understand better some variables responsible for the fragility of eyewitnesses’ accounts.More precisely, the first three studies presented in the first part of this work were dealing with an effective technique for interviewing eyewitnesses, called the Cognitive Interview. Our purpose was to develop and evaluate, in the lab and in the field, a modified version of Cognitive Interview, based on the principle of multiplication of the free recalls. However, in this dissertation, we chose to adopt a more dynamic and situational approach that the one encountered in the literature until now. Therefore, in a second part, we examined the efficacy of this protocol in interaction with three estimator variables, inseparable from the context of hearing witnesses, and which can in the real life strongly and negatively impact the quality of their accounts. These variables are: (a) the scripts shared by individuals about criminal events, (b) the talk between witnesses, and, (c) the stereotypes associated with witnesses through the social groups they belong to.Several results were shown. First, we confirmed the efficacy of a modified version of the Cognitive Interview (MCI). More precisely, a protocol composed of two free recallattempts, composed of the report all and the context reinstatement instructions, as well as a new technique designed to enhance memories, the guided peripheral focus, increased in all the studies the richness of participants’ recalls without impairing their accuracy. Its efficacy was shown in the lab and in the field. Moreover, this protocol includes the most effective cognitive instructions and omits the less beneficial. Then, in the second part, we confirmed that the scripts and the talk among witnesses have a detrimental impact on eyewitnesses’ testimonies. Some effects of the stereotypes linked to the group membership of the witness were also suggested. Finally, concerning the efficacy of the Cognitive Interview, and more precisely the modified protocol, some negative effects were observed in interaction with the three estimator variables considered. However, some interesting benefits of this protocol and of the cognitive instructions it includes were also shown.These results will be discussed in regards with the literature available today. Some applied recommendations will also be emitted.

This master‘s thesis deals with using surface texture parameters for conformity assessment and process control. The aim of the thesis was to create an overview of surface texture parameters, an overview of procedures for conformity assessment and process control using surface texture parameters, practical application on an industrial product and practical recommendations. The thesis includes an overview of profile and areal surface texture parameters, including an original translation of terms of the areal method. Methods of conformity assessment and process control in connection with the surface texture parameters are also described. Statistical analysis was performed based on 7200 values of surface parameters and 1843200 values of profile parameters which were measured on parts from serial production. The last chapter includes practical recommendations.
