The effect of noise on the voice of preschool institution educators

OBJECTIVE: To analyze the association between noise levels present in preschool institutions and vocal disorders among educators. METHODS: Cross-sectional study conducted in 2009 with 28 teachers from three preschool institutions located in the city of Sao Paulo (Southeastern Brazil). Sound pressure levels were measured according to Brazilian Technical Standards Association, with the use of a sound level meter. The averages were classified according to the levels of comfort, discomfort, and auditory damage proposed by the Pan American Health Organization. The educators underwent voice evaluation: self-assessment with visual analogue scale, auditory perceptual evaluation using the GRBAS scale, and acoustic analysis utilizing the Praat program. To analyze the association between noise and voice evaluation, descriptive statistics and the chi-square test were employed, with significance of 10% due to sample size. RESULTS: The teachers' age ranged between 21 and 56 years. The noise average was 72.7 dB, considered as damage 2. The professionals' vocal self-assessment ranked an average of 5.1 on the scale, being considered as moderate alteration. In the auditory-perceptual assessment, 74% presented vocal alteration, especially hoarseness; of these, 52% were considered mild alterations. In the acoustic assessment the majority presented fundamental frequency below the expected level. Averages for jitter, shimmer and harmonic-noise ratio showed alterations. An association between the presence of noise between the harmonics and vocal disorders was observed. CONCLUSIONS: There is an association between presence of noise between the harmonics and vocal alteration, with high noise levels. Although most teachers presented mild voice alteration, the self-evaluation showed moderate alteration, probably due to the difficulty in projection.

The Digital Economy Act in the dock: a proportionate ruling

The UK’s Digital Economy Act 2010 contains measures to enforce copyright on the Internet, specifically a two-tiered form of a graduated response.The Act was challenged in the High Court by two of the UK’s biggest Internet Service Providers (ISP), who obtained a Judicial Review of the copyright enforce- ment provisions. This paper is an overview of the case, based on the hearing of March 2011 and the ensuing judgement. It focuses on the two most hotly contested grounds for the challenge, namely an al- leged failure to notify the European Commission under the Technical Standards Directive, and the pro- portionality or otherwise of the contested provisions. It observes how the judgement accepted the defence argumentation of the government and the copyright owners as interested parties, and how the ISPs appeared to be put on the back foot.

Certificados electrónicos de servidor en administración y comercio electrónicos: garantías de seguridad

El uso de Internet por parte de los ciudadanos para relacionarse con las Administraciones Públicas o en relación con actividades de comercio electrónico crece día a día. Así lo evidencian los diferentes estudios realizados en esta materia, como los que lleva a cabo el Observatorio Nacional de las Telecomunicaciones y la Sociedad de la Información (http://www.ontsi.red.es/ontsi/). Se hace necesario, por tanto, identificar a las partes intervinientes en estas transacciones, además de dotarlas de la confidencialidad necesaria y garantizar el no repudio. Uno de los elementos que, junto con los mecanismos criptográficos apropiados, proporcionan estos requisitos, son los certificados electrónicos de servidor web. Existen numerosas publicaciones dedicadas a analizar esos mecanismos criptográficos y numerosos estudios de seguridad relacionados con los algoritmos de cifrado, simétrico y asimétrico, y el tamaño de las claves criptográficas. Sin embargo, la seguridad relacionada con el uso de los protocolos de seguridad SSL/TLS está estrechamente ligada a dos aspectos menos conocidos:  el grado de seguridad con el que se emiten los certificados electrónicos de servidor que permiten implementar dichos protocolos; y  el uso que hacen las aplicaciones software, y en especial los navegadores web, de los campos que contiene el perfil de dichos certificados. Por tanto, diferentes perfiles de certificados electrónicos de servidor y diferentes niveles de seguridad asociados al procedimiento de emisión de los mismos, dan lugar a diferentes tipos de certificados electrónicos. Si además se considera el marco jurídico que afecta a cada uno de ellos, se puede concluir que existe una tipología de certificados de servidor, con diferentes grados de seguridad o de confianza. Adicionalmente, existen otros requisitos que también pueden pasar desapercibidos tanto a los titulares de los certificados como a los usuarios de los servicios de comercio electrónico y administración electrónica. Por ejemplo, el grado de confianza que otorgan los navegadores web a las Autoridades de Certificación emisoras de los certificados y cómo estas adquieren tal condición, o la posibilidad de poder verificar el estado de revocación del certificado electrónico. El presente trabajo analiza todos estos requisitos y establece, en función de los mismos, la correspondiente tipología de certificados electrónicos de servidor web. Concretamente, las características a analizar para cada tipo de certificado son las siguientes:  Seguridad jurídica.  Normas técnicas.  Garantías sobre la verdadera identidad del dominio.  Verificación del estado de revocación.  Requisitos del Prestador de Servicios de Certificación. Los tipos de certificados electrónicos a analizar son:  Certificados de servidor web:  Certificados autofirmados y certificados emitidos por un Prestador de Servicios de Certificación.  Certificados de dominio simple y certificados multidominio (wildcard y SAN)  Certificados de validación extendida.  Certificados de sede electrónica. ABSTRACT Internet use by citizens to interact with government or with e-commerce activities is growing daily. This topic is evidenced by different studies in this area, such as those undertaken by the Observatorio Nacional de las Telecomunicaciones y la Sociedad de la Información (http://www.ontsi.red.es/ontsi/ ). Therefore, it is necessary to identify the parties involved in these transactions, as well as provide guaranties such as confidentiality and non-repudiation. One instrument which, together with appropriate cryptographic mechanisms, provides these requirements is SSL electronic certificate. There are numerous publications devoted to analyzing these cryptographic mechanisms and many studies related security encryption algorithms, symmetric and asymmetric, and the size of the cryptographic keys. However, the safety related to the use of security protocols SSL / TLS is closely linked to two lesser known aspects:  the degree of security used in issuing the SSL electronic certificates; and  the way software applications, especially web Internet browsers, work with the fields of the SSL certificates profiles. Therefore, the diversity of profiles and security levels of issuing SSL electronic certificates give rise to different types of certificates. Besides, some of these electronic certificates are affected by a specific legal framework. Consequently, it can be concluded that there are different types of SSL certificates, with different degrees of security or trustworthiness. Additionally, there are other requirements that may go unnoticed both certificate holders and users of e-commerce services and e-Government. For example, the degree of trustworthiness of the Certification Authorities and how they acquire such a condition by suppliers of Internet browsers, or the possibility to verify the revocation status of the SSL electronic certificate. This paper discusses these requirements and sets, according to them, the type of SSL electronic certificates. Specifically, the characteristics analyzed for each type of certificate are the following:  Legal security.  Technical standards.  Guarantees to the real identity of the domain.  Check the revocation status.  Requirements of the Certification Services Providers. The types of electronic certificates to be analyzed are the following:  SSL electronic certificates:  Self-signed certificates and certificates issued by a Certification Service Provider.  Single-domain certificates and multi-domain certificates (wildcard and SAN)  Extended Validation Certificates.  “Sede electrónica” certificates (specific certificates for web sites of Spanish Public Administrations).

Five-year results of a slant-path propagation experiment at 20 GHz in Madrid

Satellite operators are starting to use the Ka-band (30/20 GHz) for communications systems requiring higher traffic capacity. The use of this band is expected to experience a significant growth in the next few years, as several operators have reported plans to launch new satellites with Ka-band capacity. It is worth mentioning the Ka-Sat satellite in Europe, launched in 2010, and ViaSat-1, of 2011, with coverage of USA1. Some other examples can be found in other parts of the World. Recent satellite communications standards, such as DVB-S22 or DVB-RCS3, which provide means to mitigate propagation impairments, have been developed with the objective of improving the use of the Ka-band, in comparison with previous technical standards. In the next years, the ALPHASAT satellite will bring about new opportunities4 for carrying out propagation and telecommunication experiments in the Ka- and Q/V-bands. Commercial uses are focused on the provision of high speed data communications, for Internet access and other applications. In the near future, it is expected that higher and higher data rates will also be needed to broadcast richer multimedia contents, including HD-TV, interactive content or 3D-TV. All of these services may be provided in the future by satellites of the current generation, whose life span can extend up to 2025 in some cases. Depending on local regulations, the available bandwidth for the satellite fixed and broadcasting services in the Ka-band is in excess of several hundred MHz, bidirectional, comprising more than 1 GHz for each sub-band in some cases. In this paper, the results of a propagation experiment that is being carried out at Universidad Politécnica de Madrid (UPM), Spain, are presented5. The objective of the experiment is twofold: gathering experimental time series of attenuation and analyzing them in order to characterize the propagation channel at these frequencies6. The experiment and statistical results correspond to five complete years of measurements. The experiment is described in more detail in Section II. Yearly characteristics of rain attenuation are presented in Section III, whereas Section IV is dedicated to the monthly, seasonal, and hourly characteristics. Section V covers the dynamic characteristics of this propagation effect, just before the conclusions are described in Section VI.

Tecnologia construtiva de fachada em chapas delgadas estruturadas em light steel framing.

Aumento da produtividade, melhorias na qualidade dos produtos, redução de custos e de impactos ambientais são essenciais para a capacidade competitiva das empresas. A execução da fachada faz parte do caminho crítico da obra, por ser um subsistema que associa as funções de fechamento, acabamento, iluminação e ventilação e ainda por incorporar sistemas prediais; apresenta, por isso também, um alto custo direto em relação aos outros subsistemas do edifício. A tecnologia construtiva de fachadas em chapas delgadas com estrutura em Light Steel Framing (LSF) é uma alternativa viável para aumentar a produtividade e reduzir os prazos de obra, com qualidade e desempenho, e pode trazer benefícios em relação a atividades intensas em mão de obra como é o caso da alvenaria de vedação e de seus revestimentos. O presente trabalho tem por objetivo sistematizar e analisar o conhecimento relativo a essa tecnologia construtiva de fachada. O método adotado compreende revisão bibliográfica. Como contribuição, o trabalho reúne um conjunto organizado de informações sobre os principais sistemas disponíveis no mercado contemplando: a caracterização do sistema de fachada, de suas camadas e dos perfis leves de aço e a sistematização das principais avaliações técnicas de sistemas existentes em outros países, reunindo normas técnicas de produtos e de execução. Acredita-se que a reunião e organização das informações, antes dispersas em diversas referências, têm potencial para subsidiar o meio técnico para tomada de decisão quanto ao uso adequado da nova tecnologia.

Uma abordagem paramétrica do impacto da geração distribuída sobre as correntes de curto-circuito e na proteção de redes de distribuição.

Esta dissertação tem por propósito analisar os impactos da geração distribuída sobre as correntes de curto-circuito e sobre a proteção das redes de média tensão das concessionárias de distribuição de energia elétrica usando uma abordagem paramétrica. A principal motivação deste trabalho são os recentes incentivos regulatórios que estão fomentando a geração distribuída no Brasil. Contudo, as redes de distribuição convencionais foram projetadas para serem passivas e a introdução da geração poderá causar problemas de ordem técnica que ainda precisam ser resolvidos. Tais problemas foram pesquisados e aqueles relacionados com os impactos sobre as correntes de curto-circuito foram enfatizados. As normas técnicas das concessionárias também foram investigadas porque seus requisitos, como a ligação dos transformadores de acoplamento, influem nas correntes de curto-circuito. Para se calcular as correntes de curto-circuito, desenvolveu-se uma planilha eletrônica cujos resultados foram validados com programas comerciais de análise de redes elétricas. Esta ferramenta foi utilizada para demonstrar, através de exemplos, o impacto causado pela geração distribuída sobre as correntes de curto-circuito e, posteriormente, para realizar as análises paramétricas nas quais a influência de cada variável foi avaliada. A aplicação do método paramétrico permitiu o estudo de possíveis limites para a potência de um gerador distribuído em função dos impactos admissíveis, de seu ponto de conexão, de seus parâmetros elétricos e dos parâmetros elétricos da rede.

Diretrizes regulatórias aplicáveis à cadeia dos produtos para saúde

A ciência e a tecnologia cada vez mais vêm proporcionando avanços em produtos inovadores. Particularmente na área da saúde nota-se eminente sinergismo entre os materiais utilizados, suas propriedades de biocompatibilidade, biofuncionalidade, processabilidade, esterilidade e a área de aplicabilidade no organismo humano. O setor farmacêutico por apresentar grande complexidade exige conhecimentos multidisciplinares, atualizados e em conformidade às tendências internacionais. A Agência Nacional de Vigilância Sanitária (ANVISA) tem sob sua responsabilidade extensa diversidade de bens, serviços e produtos, dentre eles estão os correlatos, que também compreende os produtos para saúde. Os produtos para saúde são classificados conforme o seu risco, no Brasil podendo apresentar até quatro classes, sendo as classes III e IV as que caracterizam maior risco. Para alguns produtos, devido seu risco sanitário, é compulsório a Certificação de Conformidade pelo Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO) previamente a concessão de seu registro sanitário pela ANVISA. Dentre as normas técnicas aplicáveis pelo INMETRO estão as normas da Associação Brasileira de Normas Técnicas (ABNT) e na sua ausência, as normas da International Organization for Standardization (ISO). Outros requisitos técnicos e regulatórios devem ser contemplados com o propósito de comprovação da segurança e eficácia dos produtos. Entretanto, as regulamentações sanitárias inerentes a essa categoria de produtos ainda se encontram incipientes no país. A desenvoltura do setor produtivo nesse segmento pode ser evidenciada pelo aumento de novas solicitações na ANVISA e de seu crescimento na balança comercial. No entanto, observa-se pouco estudo e entendimento do setor regulado e regulador referente à relação mútua entre ANVISA, INMETRO e ABNT e quanto à regulação sanitária aplicável para obtenção da anuência do produto ao consumo. Na conjuntura das demandas apontadas o objetivo deste estudo foi avaliar o processo regulatório aplicável à cadeia produtiva dos produtos para saúde com a finalidade de compreender a relação entre ANVISA, INMETRO e ABNT na garantia da qualidade, segurança e eficácia dos produtos. A metodologia aplicada neste trabalho foi à pesquisa qualitativa. Com o auxílio da pesquisa documental constatou-se que o processo regulatório brasileiro é complexo, específico e robusto e apresenta estrutura e exigências semelhantes dos Estados Unidos e União Europeia. A fiscalização pós-uso é uma tendência internacional e a ANVISA vem adotando com frequência com intuito de acompanhar a qualidade dos produtos comercializados. As três instituições apresentam competências definidas e regulamentadas, bem como mecanismos de inter-relação por meio de conselhos consultivos. O estudo de caso caracterizou que o perfil dos profissionais do setor regulado apresenta em grande percentual formação na área da saúde e nível de pós-graduação, porém o nível de conhecimento dos principais conceitos relativos aos produtos para saúde é parcial, reforçando a necessidade de incentivos de capacitação de recursos humanos em regulação em saúde.

Russia’s Punitive Trade Policy Measures towards Ukraine, Moldova and Georgia. CEPS Working Document No. 400, September 2014

While EU and US sanctions against Russia over its aggression in Ukraine, and Russia’s counter-sanctions, are much discussed due to their evident political significance, less attention has been given to Russia’s punitive sanctions against the three Eastern European states – Ukraine, Moldova and Georgia – that have signed with the EU Association Agreements (AA), which include Deep and Comprehensive Free Trade Area (DCFTA) provisions. This paper therefore documents these trade policy restrictions and embargoes imposed by Russia, and provides some first indications of their impact. The immediate impact on trade flows, especially for agri-food products, has been substantial, albeit with some leakage through Belarus. The main instrument for the Russian measures has been allegations of non-conformity with Russian technical standards, although the correlation of these allegations with movements in Russia’s geopolitical postures makes it obvious that the Russian technical agencies are following political guidelines dressed up as scientific evidence. These measures also push the three states into diversifying their trade marketing efforts in favour of the EU and other world markets, with Georgia already having taken significant steps in this direction, since in its case the Russian sanctions date back to 2006. In the case of Ukraine, Russia’s threat to cancel CIS free trade preferences infiltrated trilateral talks between the EU, Ukraine and Russia, leading on 12 September to their proposed postponement until the end of 2015 of the ‘provisional’ implementation of a large part of the AA/DCFTA. This was immediately followed on 16 September by ratification of the AA/DCFTA by both the Rada in Kyiv and the European Parliament, which will lead to its full and definitive entry into force when the 28 EU member states have also ratified it. However Putin followed the day after with a letter to Poroshenko making an abusive interpretation of the 12 September understanding.

Digital Classics Outside the Echo-Chamber : Teaching, Knowledge Exchange and Public Engagement /

The international perspectives on these issues are especially valuable in an increasingly connected, but still institutionally and administratively diverse world. The research addressed in several chapters in this volume includes issues around technical standards bodies like EpiDoc and the TEI, engaging with ways these standards are implemented, documented, taught, used in the process of transcribing and annotating texts, and used to generate publications and as the basis for advanced textual or corpus research. Other chapters focus on various aspects of philological research and content creation, including collaborative or community driven efforts, and the issues surrounding editorial oversight, curation, maintenance and sustainability of these resources. Research into the ancient languages and linguistics, in particular Greek, and the language teaching that is a staple of our discipline, are also discussed in several chapters, in particular for ways in which advanced research methods can lead into language technologies and vice versa and ways in which the skills around teaching can be used for public engagement, and vice versa. A common thread through much of the volume is the importance of open access publication or open source development and distribution of texts, materials, tools and standards, both because of the public good provided by such models (circulating materials often already paid for out of the public purse), and the ability to reach non-standard audiences, those who cannot access rich university libraries or afford expensive print volumes. Linked Open Data is another technology that results in wide and free distribution of structured information both within and outside academic circles, and several chapters present academic work that includes ontologies and RDF, either as a direct research output or as essential part of the communication and knowledge representation. Several chapters focus not on the literary and philological side of classics, but on the study of cultural heritage, archaeology, and the material supports on which original textual and artistic material are engraved or otherwise inscribed, addressing both the capture and analysis of artefacts in both 2D and 3D, the representation of data through archaeological standards, and the importance of sharing information and expertise between the several domains both within and without academia that study, record and conserve ancient objects. Almost without exception, the authors reflect on the issues of interdisciplinarity and collaboration, the relationship between their research practice and teaching and/or communication with a wider public, and the importance of the role of the academic researcher in contemporary society and in the context of cutting edge technologies. How research is communicated in a world of instant- access blogging and 140-character micromessaging, and how our expectations of the media affect not only how we publish but how we conduct our research, are questions about which all scholars need to be aware and self-critical.

Assessing aviation e-marketplaces:a multi-criteria approach

After a proliferation of logistics e-Marketplaces during the dot.com boom of 1998-2000, there has been a high rate of failure and survivals are developing much more slowly than expected. This is the case in the aviation industry where a large number of B2B e-Marketplaces emerged according to the focus of aviation companies’ strategies on electronic B2B in the late 1990s. However, the current use of e-Marketplaces in the industry is low and many of them have ceased trading. The traditional e-Marketplaces model has been characterised by poor quality portals and a lack of technical standards. Such an approach is unsustainable in today’s competitive scenario. Improvements in website quality attributes may strongly contribute to the simplification of website functionality by users and speed up communication with all supply chain partners. In this context, it appears critical to develop models for the evaluation of e-Marketplace web sites. This chapter, after a discussion about the development of e-Marketplaces in the transport and logistics service industry and its application in the aviation industry, proposes a multi-criteria model for assessing different types of aeronautic B2B e-Marketplaces.

Avaliação da conformidade dos blocos cerâmicos produzidos em algumas cerâmicas no Rio Grande do Norte

The final quality of the works accomplished by the building construction industry depends directly on the quality of the materials supplied and used during all their phases of execution. The federal government participation and several state programs have established conditions to stimulate and require the increment of the quality level in the building construction industry´s product chain. These programs aim at the product conformity to the technical standards. Within this context, the evaluation program of the ceramic product conformity in Rio Grande do Norte state is assessing the conformity degree to Brazilian Technical Standards of ceramic bricks and tiles made in the ceramic production area in the state. In this work, is determine the degree of conformity of the sealing ceramic bricks made by some companies in different areas of the state, such as Assú, São Gonçalo do Amarante, Apodi, Parelhas, São José do Mipibu e Macaíba. Using the technical standards as a point of reference, we attempted to reproduce in the laboratory the experimental procedures to the analysis execution, according to the specifications. It was possible to determine that none of the evaluated samples are in strict conformity with the current technical standards, what reflects the real situation of the products available on the market.

Tratamento de cascalho de perfuração utilizando sistemas microemulsionados

The oil industry is one of the activities that generates more waste to the environment. The drill cuttings is a waste generated in large quantities in the drilling process and that may cause environmental damage such as soil contamination and consequently the contamination of groundwater if disposed of without prior treatment. Arises the need to develop scientific activities and research ways to adapt these wastes the current environmental standards. In the case of solid wastes, the NBR 10004: 2004 of the Brazilian Association of Technical Standards (ABNT) classifies them into class I waste (hazardous) and class II (not dangerous), which determines which wastes may or may not be discarded in the environment without causing environmental impact. This study presents a novel alternative for treating drill cuttings, where this waste was classified as class I (Abreu & Souza, 2005), mainly by removing the n-paraffin present in it, since this arises when using drilling fluids base oil. Using microemulsion systems promotes the removal of this contaminant drill cuttings samples from wells located in Alto do Rodrigues - RN. Initially, we determined the concentration of paraffin using infrared method in samples were extracted with ultrasound, we obtained a paraffin concentration in the range from 36.59 to 43.52 g of paraffin per kilogram of cuttings. Used two microemulsion systems containing two nonionic surfactants from different classes, one is an alcohol ethoxylated (UNTL-90) and the other an nonylphenol ethoxylated (RNX 110). The results indicated that the system UNTL-90 surfactant has better efficiency than the system with RNX 110. The study of the influence of contact time at the extraction showed that for times greater than 25 minutes has a tendency to increase the percentage extraction with increasing contact time. It was also observed that the extraction is fast because at 1 minute contact has 22.7% extraction. The reuse of the microemulsion system without removing the paraffin extracted in previous steps, showed reduction of 29.32 in percentage of extraction by comparing the first and third extraction, but by comparing the first and second extractions reduction is 8.5 in percentage extraction, so the systems reuse optimization can be an option for economically viable removing paraffin from cuttings. The extraction with shaking is more effective in the treatment of cuttings, reaching the extraction percentage of 87.04%, that is, obtaining a drill cuttings with 0.551% paraffin. Using the percentage of paraffin employed in non-aqueous drilling fluids and fluid maximum limit on cuttings for disposal established by the Environmental Protection Agency of the United States (US EPA), one arrives at the conclusion that the level of paraffin on gravel cannot exceed 3.93%. Conclude that the amount of paraffin in the treated cuttings with the microemulsion system with shaking is below the established by US EPA, showing that the system used was efficient in removing the paraffin from the drill cuttings.
