Avaliação das informações sobre rinite alérgica em sites brasileiros na rede mundial de computadores (Internet)

A rede mundial de computadores (Internet) é, atualmente, fonte de informação sobre saúde para leigos e profissionais da área médica. A Rinite Alérgica é uma doença muito prevalente que chega a atingir mais de 10% da população geral, causando queda da qualidade de vida. OBJETIVO: Avaliar os princípios éticos de sites brasileiros que divulgam informações a respeito do tema "rinite alérgica". FORMA DE ESTUDO: revisional. MATERIAL E MÉTODO: Foi feita avaliação de 173 sites brasileiros encontrados através de quatro mecanismos de busca (Google, Yahoo, Altavista e Radar Uol). Os sites foram avaliados de acordo com o Manual de Princípios Éticos para Sites de Medicina e Saúde do CREMESP (Conselho Regional de Medicina do Estado de São Paulo), de acordo com os itens transparência, honestidade, qualidade, consentimento livre e esclarecido, privacidade, ética médica, responsabilidade e procedência. RESULTADOS: Entre os sites analisados, 149 (86,1%) não estavam de acordo como Manual de Princípios Éticos para Sites de Medicina e Saúde do CREMESP. As proporções de irregularidades entre os itens avaliados foram: qualidade (84,4%), privacidade (46,2%) honestidade (18,5%), consentimento livre e esclarecido (15,6%), responsabilidade (13,9%), transparência (12,1%), ética médica (2,3%). Havia informações inexatas em 24,3% dos sites analisados. CONCLUSÕES: A maioria dos sites estudados contendo informações sobre rinite alérgica fere os princípios éticos para sites do CREMESP. Tanto a qualidade em geral de grande parte dos sites brasileiros que abordam o tema "rinite alérgica", quanto à qualidade das informações por eles divulgadas, são insuficientes para satisfazer a médicos e pacientes.

Análisis de la producción científica visible en internet de los técnicos de salud ambiental del Servicio Andaluz de Salud

Internet it is a powerful interactive communication channel with world scope, through which can be multiplied the visibility of the research of the professionals whose scientific production has a difficult diffusion by the conventionals media. It is presented an analysis of the scientific publications observed in the web in order to understand the different communication processes accomplished by the superior corps of environmental health technical of the Andalusian Health Service. Using the nominal relationship of the professionals, we used Google ‘search engine’ for all scientific publications located in the internet; we were made different bibliometric indicators as of the recovered records and was analyzed the time evolution of the scientific production, documental categories, geografic distribution, language, coauthors and institutional collaboration. It was identified a growing trend in the productivity of the publications in the last decade, mainly through communications to congresses (70.4%) and journals articles (16.9%). The publications mainly are located in spanish journals, that they are indexed on national and international databases. In all the Andalusian provinces was identified some published scientific communication. The indicator of coauthors is very high (95.77%) although the institutional participation is limited mainly to the primary attention districts, occupational centers of each professional (85.21%). The scientific publication patterns visualized in the web represent an important contribution for the knowledge of the characteristics of the environmental health professionals of the Andalusian health service, what provides avaluable information for the support of the information systems in public health.

Anàlisi de llocs webs en català i castellà que promouen la no vacunació a Internet

La incidència de les malalties que es poden prevenir mitjançant la vacunació està relacionada amb el nombre de nens no vacunats. Els pares que es neguen a vacunar als seus fills expressen amb freqüència la seva preocupació per la seguretat de les vacunes. Internet podria influir en la seva percepció de la seguretat vers la vacunació, atès que és una font en creixement sobre temes de salut. Malgrat això, pocs estudis han analitzat la possible incidència que poden exercir les webs que promulguen la no vacunació sobre els pares. L'objectiu d'aquest treball és analitzar les webs trobades mitjançant Google i Bing que ofereixin continguts "anti vacunació" en català i castellà. Aquest estudi proporciona l'anàlisi de les 16 webs trobades en aquestes llengües que acompleixen les variables establertes com 'anti vacunació' en estudis realitzats en altres idiomes i territoris: totes aquestes webs publicades en castellà i català aboquen dures crítiques vers la vacunació. Atesa la importància de la qüestió, es recomana aprofundir en la mateixa línea d'investigació utilitzant altres equacions en la recerca.

La diversidad cultural en Google y los motores de búsqueda: una aproximación conceptual

Se analiza una preocupación expresada tanto de forma implícita como explícita en diversos ámbitos, según la cual los motores de búsqueda en general y Google en particular, podrían estar utilizando algún sistema para ocultar determinados contenidos culturales o bien para destacar aquellos que proceden del ámbito anglosajón en detrimento de los de otras culturas y lenguas. Dicho de otro modo, se considera, en una primera aproximación de modo exclusivamente conceptual, la idea de si el uso intensivo de los motores de búsqueda, tan característico de nuestro tiempo, resulta una amenaza para la diversidad cultural. Para ello, en primer lugar y con el fin de contextualizar este trabajo, se lleva a cabo una presentación de dos polémicas previas sobre el dilema proteccionismo o libre flujo de los productos culturales y a continuación se analizan las características más relevantes de los motores de búsqueda (centrándonos en Google en particular) con el fin de valorar si éstos constituyen una amenaza creíble a la diversidad cultural e idiomática de la Web.

Qualités des sites internet anglophones traitant du trouble obsessionnel complusif

Enjeux et contexte : Dans les questions de santé mentale, internet constitue de plus en plus une source d'information pour les personnes souffrant de troubles psychiatriques ainsi que de leurs proches. D'autre part, le trouble obsessionnel compulsif revêt une importance grandissante et bénéficie d'un intérêt croissant en raison de sa fréquence et de la charge qu'il représente pour le patient et pour la société. Les patients souffrant de trouble obsessionnel compulsif, qu'ils soient diagnostiqués ou non, ainsi que leurs proches peuvent être amenés à rechercher une information de bonne qualité sur net sur le sujet. Cette étude vise à évaluer la qualité de l'information issue de l'internet concernant les sites anglophones traitant du trouble obsessionnel compulsif et de comparer les résultats des requêtes en utilisant un moteur de recherche général (Google) à celles obtenues avec un moteur de recherche spécialisé (Omni Medical Search). Des mots-clés relatifs au trouble obsessionnel compulsif ont été introduits dans Google et Omni Medical Search. Les sites retenus ont été évalués selon leur responsabilité, interactivité, lisibilité et la qualité de leur contenu. Le Label HON et la version brève de l'échelle DISCERN ont été utilisés comme indicateurs possibles de la qualité du contenu. Sur les 235 adresses retrouvées, 53 sites retenus ont été analysés. Résultats : La qualité du contenu des sites examinés est relativement bonne. L'utilisation d'un moteur de recherche spécialisé ne constitue pas un avantage par comparaison au moteur général utilisé par la grande majorité des internautes. Un score > 16 de la version brève du DISCERN est associé à une meilleure qualité du contenu. En conclusion : cette étude montre que le contenu des sites web concernant le trouble obsessionnel compulsif est acceptable. L'utilisation d'un moteur de recherche spécialisé n'offre pas d'avantage par rapport à Google. Comme implications pratiques : internet renferme des sites de haute qualité sur le trouble obsessionnel compulsif. L'accès à ces sites ne nécessite pas l'utilisation d'un moteur de recherche spécialisé. En revanche, une discussion entre le patient et le soignant à propos de l'information disponible sur internet demeure indispensable Perspectives : en dépit des limitations de notre étude, on peut dire que l'information contenue dans le web concernant le trouble obsessionnel compulsif est acceptable. Le contenu et la présentation de cette information pourraient être améliorés. Quant à l'internaute qui cherche une information de qualité, il pourrait être guidé par deux éléments : le HON et la version brève du DISCERN.

Three essays on major trends in a slow clockspeed industry : the case of industrial automation

The motivation for this research initiated from the abrupt rise and fall of minicomputers which were initially used both for industrial automation and business applications due to their significantly lower cost than their predecessors, the mainframes. Later industrial automation developed its own vertically integrated hardware and software to address the application needs of uninterrupted operations, real-time control and resilience to harsh environmental conditions. This has led to the creation of an independent industry, namely industrial automation used in PLC, DCS, SCADA and robot control systems. This industry employs today over 200'000 people in a profitable slow clockspeed context in contrast to the two mainstream computing industries of information technology (IT) focused on business applications and telecommunications focused on communications networks and hand-held devices. Already in 1990s it was foreseen that IT and communication would merge into one Information and communication industry (ICT). The fundamental question of the thesis is: Could industrial automation leverage a common technology platform with the newly formed ICT industry? Computer systems dominated by complex instruction set computers (CISC) were challenged during 1990s with higher performance reduced instruction set computers (RISC). RISC started to evolve parallel to the constant advancement of Moore's law. These developments created the high performance and low energy consumption System-on-Chip architecture (SoC). Unlike to the CISC processors RISC processor architecture is a separate industry from the RISC chip manufacturing industry. It also has several hardware independent software platforms consisting of integrated operating system, development environment, user interface and application market which enables customers to have more choices due to hardware independent real time capable software applications. An architecture disruption merged and the smartphone and tablet market were formed with new rules and new key players in the ICT industry. Today there are more RISC computer systems running Linux (or other Unix variants) than any other computer system. The astonishing rise of SoC based technologies and related software platforms in smartphones created in unit terms the largest installed base ever seen in the history of computers and is now being further extended by tablets. An underlying additional element of this transition is the increasing role of open source technologies both in software and hardware. This has driven the microprocessor based personal computer industry with few dominating closed operating system platforms into a steep decline. A significant factor in this process has been the separation of processor architecture and processor chip production and operating systems and application development platforms merger into integrated software platforms with proprietary application markets. Furthermore the pay-by-click marketing has changed the way applications development is compensated: Three essays on major trends in a slow clockspeed industry: The case of industrial automation 2014 freeware, ad based or licensed - all at a lower price and used by a wider customer base than ever before. Moreover, the concept of software maintenance contract is very remote in the app world. However, as a slow clockspeed industry, industrial automation has remained intact during the disruptions based on SoC and related software platforms in the ICT industries. Industrial automation incumbents continue to supply systems based on vertically integrated systems consisting of proprietary software and proprietary mainly microprocessor based hardware. They enjoy admirable profitability levels on a very narrow customer base due to strong technology-enabled customer lock-in and customers' high risk leverage as their production is dependent on fault-free operation of the industrial automation systems. When will this balance of power be disrupted? The thesis suggests how industrial automation could join the mainstream ICT industry and create an information, communication and automation (ICAT) industry. Lately the Internet of Things (loT) and weightless networks, a new standard leveraging frequency channels earlier occupied by TV broadcasting, have gradually started to change the rigid world of Machine to Machine (M2M) interaction. It is foreseeable that enough momentum will be created that the industrial automation market will in due course face an architecture disruption empowered by these new trends. This thesis examines the current state of industrial automation subject to the competition between the incumbents firstly through a research on cost competitiveness efforts in captive outsourcing of engineering, research and development and secondly researching process re- engineering in the case of complex system global software support. Thirdly we investigate the industry actors', namely customers, incumbents and newcomers, views on the future direction of industrial automation and conclude with our assessments of the possible routes industrial automation could advance taking into account the looming rise of the Internet of Things (loT) and weightless networks. Industrial automation is an industry dominated by a handful of global players each of them focusing on maintaining their own proprietary solutions. The rise of de facto standards like IBM PC, Unix and Linux and SoC leveraged by IBM, Compaq, Dell, HP, ARM, Apple, Google, Samsung and others have created new markets of personal computers, smartphone and tablets and will eventually also impact industrial automation through game changing commoditization and related control point and business model changes. This trend will inevitably continue, but the transition to a commoditized industrial automation will not happen in the near future.

The unfathomable secret remains: a reverse engineering study of SEO factors on Google's search engine

The vast majority of users don’t seek results beyond the second page offered by the search engine, so if a site fails to be among the top 20 (second page), it says that this page does not have good SEO and, therefore, is not visible to the user. The overall objective of this project is to conduct a study to discover the factors that determine (or not) the positioning of websites in a search engine.

In Google we trust?

In a micro-founded model, we derive novel incentives for a monopoly search engine to distort its organic and its sponsored results on searches for online content and offline products. Distorting organic results towards content publishers with less effective display advertising and/or distorting sponsored results towards higher margin merchants (by underweighting consumer relevance in search auctions) increase per capita revenues but lower participation. The interplay of these incentives determines search bias and welfare. We also characterize how the welfare consequences of integration into display advertising, as intermediary or publisher, depend on asymmetries, monopolization and targeting.

Web-sovellus Google App Engine alustalle

App Engine on lyhenne englanninkielisistä termeistä application, sovellus ja engine, moottori. Kyseessä on Google, Inc. -konsernin toteuttama kaupallinen palvelu, joka noudattaa pilvimallin tietojenkäsittelyn periaatteita ja mahdollistaa asiakkaan oman sovelluskehityksen. Järjestelmään on mahdollista ohjelmoida itse ideoitu palvelu Internet - verkon välityksellä käytettäväksi, joko yksityisesti tai julkisesti. Kyse on siis hajautetusta palvelinjärjestelmästä, jonka tarjoaa dynaamisesti kuormitukseen sopeutuvan sovellusalustan, jossa asiakas ei vuokraa virtuaalikoneita. Myös järjestelmän tarjoama tallennuskapasiteetti on saatavilla joustavasti. Itse kandidaatintyössä syvennytään yksityiskohtaisemmin sovelluksen toteuttamiseen palvelussa, rajoitteisiin ja soveltuvuuteen. Alussa käydään läpi pilvikäsite, joista monilla tietokoneiden käyttäjillä on epäselvä käsitys. Erilaisia kokonaisuuksia voidaan luoda erittäin monella tavalla, joista rajaamme käsittelyn kohteeksi toteuttamiskelpoiset yleiset ratkaisut.

SDN in an ISP Environment

As computer networks grow larger and more complex there is a need for a new, simpler kind of approach to configuring them. Software Defined Networking (SDN) takes the control plane away from individual nodes and centralizes the network control by utilizing a flow based traffic management. In this thesis the suitability of SDN in a small ISP (Internet Service Provider) network is considered for an alternative to the current traditional core network and access network OSSs (Operations Support System), mainly to simplify the network management but also to see what else would SDN offer for such an environment. Combining information learned from a theoretical study on the matter to a more practical experiment of SDN network simulation using Mininet simulation software and OpenDayLight SDN controller software does this. Although the simulation shows that SDN is able to provide the functionality needed for the network, the immaturity of the technology suggests that for a small ISP network there is no need to utilize SDN just yet. For when SDN becomes more commonplace a brief transition plan is introduced.
