Factores asociados a recuperación visual deficiente después de cirugía exitosa para desprendimiento de retina regmatógeno

Introducción: Varias características pueden afectar el pronóstico visual después de resolver quirúrgicamente el desprendimiento de retina. Existen características no observables por el ojo humano por si solo pero si por tomografía óptica coherente que se relacionan con la recuperación visual. Objetivo: Describir las características clínicas y topográfica en los periodos pre y postquirúrgico de ojos que ha sufrido DR regmatógeno con compromiso macular y su relación con la calidad de recuperación visual después de una cirugía considerada exitosa desde el punto de vista anatómico. Materiales y métodos: Estudio descriptivo en el que se comparan algunas características en tres periodos perioeperatorios, uno antes y dos después de cirugía (3 y 6 meses) de 24 ojos con DRregmatógeno y compromiso macular intervenidos mediante retinopexia combinada con vitrectomía pars plana. Resultados: La recuperación visual mejor o igual que logMAR 0,397 (20/50) se dió en 41,7% de ojos y 16,7%. alcanzaron agudeza visual logMAR 0,301 (20/40). Cinco ojos no alcanzaron una ganancia de líneas de visión mayor a cinco. El líquido submacular ausente se observó en la mayoría de ojos que recuperaron más de cinco líneas al igual que aquellos con elipsoide conservado. La regularidad del neuroepitelio y el edema en el periodo posquirúrgico no mostraron comportamientos claros respecto a recuperación visual al igual que la altura del desprendimiento y el número de cuadrantes afectados. Una mejor recuperación visual fue más frecuente en aquellos con menos de cinco semanas de desprendimiento de retina. Conclusiones: El retraso menor a cinco semanas en la resolución del desprendimiento de retina, la conservación del elipsoide y la ausencia de líquido submacular en el periodo postquirúrgico se observó más frecuentemente en ojos con mejor recuperación visual.

Programa de prevenção primária da sinistralidade rodoviária com adolescentes – “estrada 0%”

Devido à elevada sinistralidade rodoviária que ainda se faz sentir em Portugal e apesar de ser um fenómeno resultante de diversos factores, este estudo tem como principal objectivo reduzir o consumo de substâncias na prática da condução através de um programa de prevenção primária com adolescentes denominado “Estrada 0%”. Neste programa de prevenção as substâncias abordadas em profundidade são o álcool, cannabis e a cocaína, pois acredita-se serem as mais consumidas entre os jovens na actualidade. O programa é aplicado a jovens com idades compreendidas entre os 15 – 18 anos em meio escolar com a duração de dois anos lectivos. Na primeira fase é trabalhado com os adolescentes as competências sociais e pessoais e na segunda fase os mesmos serão os agentes divulgadores na escola e comunidade da problemática de conduzir sobre o efeito de drogas.

Reencantar a educação : a educação básica e a ressocialização dos presos

Esta dissertação teve como objetivo descrever a educação básica no contexto do sistema penitenciário de Salvador em termos de processos educacionais e da Proposta Político-Pedagógica (PPP) com vistas à ressocialização do preso. Especificamente: a) descrever a realidade educacional do sistema penitenciário; b) analisar o processo educacional, método em termos de restauração pessoal, quanto à ressocialização do apenado. Em termos de percurso metodológico, quanto à natureza da pesquisa, trata-se de um estudo qualitativo. Organizou-se a dissertação, dando-lhe coerência e direção. A fundamentação teórica foi organizada delimitando-se os pontos essenciais da investigação. Em termos de tipo de pesquisa qualitativa, trata-se de estudo de caso, o qual vai-se valer, em termos de coleta de dados, da observação, entrevistas, narrativas e análise de documentos. Há que se observar que se torna difícil a situação de reintegração social do regresso, principalmente no tocante à sua recolocação profissional, pois vive-se hoje a realidade de um desemprego generalizado com elevado contingente de trabalhadores desempregados, e que ainda na maioria das vezes ainda contam com experiência profissional. A situação torna-se difícil para uma pessoa que traz consigo o estigma de ex-presidiário, e que na maioria das vezes não tem qualquer qualificação profissional. A „recuperação‟ do preso passa pela manutenção de sua referência com o mundo exterior, tais como a família, o meio de trabalho, o bairro onde reside. Quanto mais essas referências forem afastadas (e o são), mais difícil será sua readaptação posterior à sociedade. Pode ser que, após um longo período, adaptado pelas forças de sua instituição total, o mesmo já não consiga se adaptar a uma sociedade livre.

Are cold winters in Europe associated with low solar activity?

Solar activity during the current sunspot minimum has fallen to levels unknown since the start of the 20th century. The Maunder minimum (about 1650–1700) was a prolonged episode of low solar activity which coincided with more severe winters in the United Kingdom and continental Europe. Motivated by recent relatively cold winters in the UK, we investigate the possible connection with solar activity. We identify regionally anomalous cold winters by detrending the Central England temperature (CET) record using reconstructions of the northern hemisphere mean temperature. We show that cold winter excursions from the hemispheric trend occur more commonly in the UK during low solar activity, consistent with the solar influence on the occurrence of persistent blocking events in the eastern Atlantic. We stress that this is a regional and seasonal effect relating to European winters and not a global effect. Average solar activity has declined rapidly since 1985 and cosmogenic isotopes suggest an 8% chance of a return to Maunder minimum conditions within the next 50 years (Lockwood 2010 Proc. R. Soc. A 466 303–29): the results presented here indicate that, despite hemispheric warming, the UK and Europe could experience more cold winters than during recent decades.

Profiling management for personalised multimedia delivery on-demand within the AXMEDIS framework

Media content distribution on-demand becomes more complex when performed on a mass scale involving various channels with distinct and dynamic network characteristics, and, deploying a variety of terminal devices offering a wide range of capabilities. It is practically impossible to create and prepackage various static versions of the same content to match all the varying demand parameters of clients for various contexts. In this paper we present a profiling management approach for dynamically personalised media content delivery on-demand integrated with the AXMEDIS Framework. The client profiles comprise the representation of User, Device, Network and Context of content delivery based on MPEG-21:DIA. Although the most challenging proving ground for this personalised content delivery has been the mobile testbed i.e. the distribution to mobile handsets, the framework described here can be deployed for disribution, by the AXMEDIS PnP module, through other channels e.g. satellite, Internet to a range of client terminals e.g. desktops, kiosks, IPtv and other terrminals whose baseline terminal capabilities can be made availabe by the manufacturers as is normal.

Security, trust and privacy supported by context-aware middleware

Driven by new network and middleware technologies such as mobile broadband, near-field communication, and context awareness the so-called ambient lifestyle will foster innovative use cases in building automation, healthcare and agriculture. In the EU project Hydra1 highlevel security, trust and privacy concerns such as loss of control, profiling and surveillance are considered at the outset. At the end of this project the Hydra middleware development platform will have been designed so as to enable developers to realise secure ambient scenarios especially in the user domains of building automation, healthcare, and agriculture. This paper gives a short introduction to the Hydra project, its user domains and its approach to ensure security by design. Based on the results of a focus group analysis of the building automation domain typical threats are evaluated and their risks are assessed. Then, specific security requirements with respect to security, privacy, and trust are derived in order to incorporate them into the Hydra Security Meta Model. How concepts such as context security, semantic security, and virtualisation support the overall Hydra approach will be introduced and illustrated on the basis of a technical building automation scenario.

Towards semantic resolution of security in ambient environments

Driven by new network and middleware technologies such as mobile broadband, near-field communication, and context awareness the so-called ambient lifestyle will foster innovative use cases in different domains.

Genetic diversity of red-fleshed apples (Malus)

Anthocyanins are flavonoid pigments imparting red, blue, or purple pigmentation to fruits, flowers and foliage. These compounds are powerful antioxidants in vitro, and are widely believed to contribute to human health. The fruit of the domestic apple (Malus x domestica) is a popular and important source of nutrients, and is considered one of the top ‘functional foods’—those foods that have inherent health-promoting benefits beyond basic nutritional value. The pigmentation of typical red apple fruits results from accumulation of anthocyanin in the skin. However, numerous genotypes of Malus are known that synthesize anthocyanin in additional fruit tissues including the core and cortex (flesh). Red-fleshed apple genotypes are an attractive starting point for development of novel varieties for consumption and nutraceutical use through traditional breeding and biotechnology. However, cultivar development is limited by lack of characterization of the diversity of genetic backgrounds showing this trait. We identified and cataloged red-fleshed apple genotypes from four Malus diversity collections representing over 3,000 accessions including domestic cultivars, wild species, and named hybrids. We found a striking range of flesh color intensity and pattern among accessions, including those carrying the MYB10 R 6 allele conferring ectopic expression of a key transcriptional regulator of anthocyanin biosynthesis. Although MYB10 R 6 was strongly associated with red-fleshed fruit among genotypes, this allele was neither sufficient nor required for this trait in all genotypes. Nearly all red-fleshed accessions tested could be traced back to ‘Niedzwetzkyana’, a presumed natural form of M. sieversii native to central Asia.

Standardized test to evaluate numerical weather prediction algorithms

In order to assist in comparing the computational techniques used in different models, the authors propose a standardized set of one-dimensional numerical experiments that could be completed for each model. The results of these experiments, with a simplified form of the computational representation for advection, diffusion, pressure gradient term, Coriolis term, and filter used in the models, should be reported in the peer-reviewed literature. Specific recommendations are described in this paper.

Collaboration model for SSMEnetUK: a service science perspective

This paper aims to design a collaboration model for a Knowledge Community - SSMEnetUK. The research identifies SSMEnetUK as a socio-technical system and uses the core concepts of Service Science to explore the subject domain. The paper is positioned within the concept of Knowledge Management (KM) and utilising Web 2.0 tools for collaboration. A qualitative case study method was adopted and multiple data sources were used. In achieving that, the degree of co-relation between knowledge management activities and Web 2.0 tools for collaboration in the scenario are pitted against the concept of value propositions offered by both customer/user and service provider. The proposed model provides a better understanding of how Knowledge Management and Web 2.0 tools can enable effective collaboration within SSMEnetUK. This research is relevant to the wider service design and innovation community because it provides a basis for building a service-centric collaboration platform for the benefit of both customer/user and service provider.
