Identificação de utilizadores: a chave para a personalização de aplicações de TV interativa para seniores?

A televisão é uma atividade pessoal comumente motivada pela tentativa de satisfazer aspetos relacionados com vigilância, identidade pessoal, relações pessoais e de distração (McQuail, 1987). Alguns destes aspetos são potenciados quando se trata de espectadores seniores que, muitas vezes, sofrem de solidão e isolamento. Suportados nesta realidade e nos desenvolvimentos tecnológicos ao nível das infraestruturas de difusão, os operadores do mercado televisivo estão a apostar cada vez mais na personalização da experiência televisiva. Contudo, para potenciar esta personalização, tornase essencial integrar um sistema de identificação (sID) de utilizadores, que permita que os serviços de televisão interativa respondam de forma adequada em função de quem está, realmente, a interagir com as suas funcionalidades. Neste artigo pretende-se apresentar o processo de identificação e de aferição do conjunto de variáveis funcionais que um fornecedor de televisão interativa deverá considerar, aquando da seleção do sistema de identificação mais adequado para utilizadores seniores.Watch TV is a social activity motivated by feelings of comfort, happiness, social relationships and leisure (McQuail, 1987). When seniors are in front of TV set some of these emotional states are enhanced most of the times due to isolation and loneliness. Considering this reality and the technological developments in diffusion networks, the TV operators are betting on TV experience personalization. Despite this fact, to boost the personalization, it is necessary to integrate a user identification system (sID) that allows the development of interactive TV services, which provides functionalities perfectly tuned with the person in front of TV set, using user identification info. In this work we present the set of variables and the measure techniques for each one that the TV provider should consider to select the user identification system (sID) more suitable for a senior user

Eficiencia técnica de bienes y servicios culturales: un análisis del caso mexicano

The study of Cultural Economics is increasingly more important in the world, and it has a number of different aspects to be analyzed. However, in Mexico, it is an emerging activity despite the fact that, nowadays, the information about cultural economic indicators is available since 2008. The lack of research on this topic in Mexico, from the perspective of Economic Sciences, begs the question of how the usage of factors is taking place, and if they are being used in an optimal way or, in other words, with efficiency. As a result, the objective of this research is to obtain an indicator of technical efficiency for the components of cultural goods and services in Mexico that allows us to contribute to the understanding of these activities from an economic perspective. In order to achieve the objective mentioned earlier, this study uses the methodology of Stochastic Frontier Analysis through an econometric application of panel data. Among the main findings, it was noticed that the cultural goods and services are highly efficient in an aggregated manner, as it was obtained an indicator close to 100 percent. In a disaggregated manner, the components of cultural services are more efficient compared to the cultural goods. Additionally, in a disaggregated manner, the efficiency average is 67%. Therefore, it is still possible to improve the usage of productive factors in a 33%

Biotechnological potential of Phospholipase D for Loxosceles antivenom development

Loxoscelism is one of the most important forms of araneism in South America. The Health Authorities from countries with the highest incidence and longer history in registering loxoscelism cases indicate that specific antivenom should be administered during the first hours after the accident, especially in the presence or at risk of the most severe clinical outcome. Current antivenoms are based on immunoglobulins or their fragments, obtained from plasma of hyperimmunized horses. Antivenom has been produced using the same traditional techniques for more than 120 years. Although the whole composition of the spider venom remains unknown, the discovery and biotechnological production of the phospholipase D enzymes represented a milestone for the knowledge of the physiopathology of envenomation and for the introduction of new innovative tools in antivenom production. The fact that this protein is a principal toxin of the venom opens the possibility of replacing the use of whole venom as an immunogen, an attractive alternative considering the laborious techniques and low yields associated with venom extraction. This challenge warrants technological innovation to facilitate production and obtain more effective antidotes. In this review, we compile the reported studies, examining the advances in the expression and application of phospholipase D as a new immunogen and how the new biotechnological tools have introduced some degree of innovation in this field.Fil: Fingermann, Matias.

Sulfanilic acid-modified chitosan mini-spheres and their application for lysozyme purification from egg white

A cation exchange matrix with zwitterionic and multimodal properties was synthesized by a simple reaction sequence coupling sulfanilic acid to a chitosan based support. The novel chromatographic matrix was physico-chemically characterized by ss-NMR and ζ potential, and its chromatographic performance was evaluated for lysozyme purification from diluted egg white. The maximum adsorption capacity, calculated according to Langmuir adsorption isotherm, was 50.07 ± 1.47 mg g-1 while the dissociation constant was 0.074 ± 0.012 mg mL-1 . The process for lysozyme purification from egg white was optimized, with 81.9% yield and a purity degree of 86.5%, according to RP-HPLC analysis. This work shows novel possible applications of chitosan based materials. The simple synthesis reactions combined with the simple mode of use of the chitosan matrix represents a novel method to purify proteins from raw starting materials.Fil: Hirsch, Daniela Belén.

Local head loss for uncoaxial drippers inserted in polyethylene pipes

Este trabalho apresenta os resultados de experimento conduzido para avaliar as perdas de carga localizadas em gotejados não coaxiais integrados a tubos de polietileno. As perdas de carga para diferentes vazões foram determinadas em quatro modelos de tubos-gotejadores, com dez repetições. Para cada vazão, a perda de carga localizada foi calculada pela diferença entre a perda de carga no tubo com emissor e a perda de carga contínua no tubo uniforme estimada pela equação de Darcy-Weisbach com o fator de atrito (f) previamente determinado. Aproximações matemáticas foram sugeridas para calcular hfe com base no coeficiente de carga cinética (K) e em um valor constante de comprimento equivalente (Le). Para os modelos de tubos-gotejadores estudados, a perda de carga localizada, expressa como percentagem da perda de carga total, aumentou com o aumento da razão de obstrução, variando de 24,5% a 50,8% para Ag/At = 0,221 e 0,429, respectivamente. A maior diferença percentual encontrada entre a perda de carga total calculada pelo método iterativo passo a passo e pelo uso de Le constante, calculado com a vazão de entrada na lateral, foi 5,5% para o gotejador não autocompensante. Para os gotejadores autocompensantes, as diferenças foram inferiores a 1,7%.In this paper, the results of an experimental investigation on local head losses from uncoaxial in-line emitters inserted into the pipe line are reported. Local losses corresponding to four different pipe-emitter combinations, with ten replications, were measured for a range of discharge values. For each discharge, the amount of local losses was calculated as the difference between the total measured head losses and the corresponding friction losses evaluated by the Darcy-Weisbach equation. Mathematical approaches were tested to calculate hfe based on the kinetic head coefficient (K) and constant equivalent length (Le). For the drip-line models examined, the amount of local losses, expressed as a percentage of the total losses, was found to grow with an increase in the obstruction degree. The percentage increased to 24.5% and 50.8%, respectively, for Ag/At = 0.221 and 0.429. The results of this experimental investigation indicated the practical validity of using a constant equivalent length (Le) to estimate the local head losses in a drip lateral line. The percentage variation between total head loss calculated by a step-by-step procedure and the Le approximation method was 5.5% for non-compensating pressure emitters and less than 1.7% for the pressure compensating emitters.Ministério da Ciência e TecnologiaConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Instituto Nacional de Ciência e Tecnologia em Engenharia da Irrigação (INCT-EI

'Thompson' atemoya grafting onto Rollinia rootstocks

Este estudo teve por finalidade avaliar o índice de sobrevivência do enxerto de atemoia 'Thompson' sobre dois porta-enxertos. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2 x 2, dois porta-enxertos [araticum-de-terra-fria (Rollinia sp.) e biribá (Rollinia mucosa)] e dois métodos de enxertia (topo em fenda lateral e topo à inglesa simples), em 6 blocos, 4 tratamentos e 5 plantas por parcela, totalizando 120 plantas. Para as condições locais, verificou-se que a atemoia pode ser propagada com sucesso via enxertia, usando o porta-enxerto araticum-de-terra-fria, com diferença significativa em relação ao biribá. O melhor método de enxertia para araticum-de-terra-fria foi o inglês simples, com índice de sobrevivência do enxerto de 90%. Observou-se baixo índice de sobrevivência do enxerto, utilizando-se de ambos os métodos de enxertia para o porta-enxerto biribá. ________________________________________________________________________________ ABSTRACTThis study aimed to evaluate the survival rate of atemoya 'Thompson' on two rootstocks.The experimental design used was in randomized blocks with factorial scheme 2 x 2 consisting of 6 blocks, 4 treatments and 5 replicates per parcel totaling 120 plants.

Local Head Loss of Non-Coaxial Emitters Inserted in Polyethylene Pipe

The design of a lateral line for drip irrigation requires accurate evaluation of head losses in not only the pipe but in the emitters as well. A procedure was developed to determine localized head losses within the emitters by the formulation of a mathematical model that accounts for the obstruction caused by the insertion point. These localized losses can be significant when compared with the total head losses within the system due to the large number of emitters typically installed along the lateral line. An experiment was carried out by altering flow characteristics to create Reynolds numbers (R) from 7,480 to 32,597 to provide turbulent flow and a maximum velocity of 2.0 m s-1. The geometry of the emitter was determined by an optical projector and sensor. An equation was formulated to facilitate the localized head loss calculation using the geometric characteristics of the emitter (emitter length, obstruction ratio, and contraction coefficient). The mathematical model was tested using laboratory measurements on four emitters. The local head loss was accurately estimated for the Uniram (difference of +13.6%) and Drip Net (difference of +7.7%) emitters, while appreciable deviations were found for the Twin Plus (-21.8%) and Tiran (+50%) emitters. The head loss estimated by the model was sensitive to the variations in the obstruction area of the emitter. However, the variations in the local head loss did not result in significant variations in the maximum length of the lateral lines. In general, for all the analyzed emitters, a 50% increase in the local head loss for the emitters resulted in less than an 8% reduction in the maximum lateral length

Identificação de utilizadores em IPTV- melhorar a experiência de utilização dos seniores

Watching TV is changing and becoming more personalized as we witness a spread use of interactive television, Personal Video Recorders (PVR) and Set-Top-Boxes (STB) enabling access to time-shifted content and a large range of interactive services. However, this technological mediation does not guarantee by itself an effective personalization of content, since it relies on the STB identification being not appropriated for a multi-viewer scenario. So, knowledge about who is in front of TV set becomes of paramount importance, especially for TV operators’ they can provide services perfectly targeted to the viewers. In this context, elderly (avid consumers of television) are a specific type of users that can benefit from services based on a non-intrusive identification system. This work aims to study this issue and identify a layer of customizable services which can improve the viewing experience of elderly.FCTiNeighbour TVPTDC/CCICOM/100824/200
