Cognitive intervention protocol for age-related memory impairments

With the number of elderly people increasing tremendously worldwide, comes the need for effective methods to maintain or improve older adults' cognitive performance. Using continuous neurofeedback, through the use of EEG techniques, people can learn how to train and alter their brain electrical activity. A software platform that puts together the proposed rehabilitation methodology has been developed: a digital game protocol that supports neurofeedback training of alpha and theta rhythms, by reading the EEG activity and presenting it back to the subject, interleaved with neurocognitive tasks such as n-Back and Corsi Block-Tapping. This tool will be used as a potential rehabilitative platform for age-related memory impairments.

A Digital Game Development Education Project

The success of the digital game industry is spawning several undergraduate degrees aiming at the training of digital game developers. Building adequate new courses curricula is not a trivial task and demands a profound analysis of the scientific areas to introduce as well as the dependencies throughout the entire degree. Another important aspect of every academic educational plan are the satellite projects that promote entrepreneurship and provide practical professional experiences to students. This paper presents the main guidelines adopted in the creation of the first digital game development undergraduate degree created in Portugal.

Thermal skin reference values in healthy late pregnancy

Digital thermal imaging has been employed in medicine for over 50 years. However, its use has been focused on vascular, musculoskeletal and neurological conditions, while other potential applications,such as obstetrics, have been much less explored. This paper presents a study conducted during 2011 at the Hospital of Braga on a group of healthy pregnant women in the last third of gestation. The analysis focused on characterizing typical pregnant women steady temperature profiles in specific defined regions of interest (ROI), and determining if the thermal symmetry values for late pregnant healthy women are in line with the values for non-pregnant healthy women. A temperature distribution pattern was found in the defined ROI. The obtained thermal symmetry value had a maximum of 0.370.2 1C, and there was no evidence for the influence of age (p40.05) in the observed group. The influence of the BMI requires further investigation since one ROI (P2 right) presented a p¼0.059, close to the threshold of statistical evidence in the influence of BMI. The study group presented symmetry values in line with non-pregnant reference values, but the profiles in temperature distribution are different. Assumptions can therefore now be used with higher confidence when assessing abnormalities in specific pathologic states during pregnancy using the defined ROI. This work represents a first contribution towards establishing guidelines for future research in this specific field of study.

Contradiction between the average age of retirement at the time of death and the average pension time for men and women in public employment in Portugal

The short article attempts to make some very brief reflections on the effects a lack of public policies positively discriminatory in terms of public employment retirement. In particular, the observation of the absurd contradiction between the average age of retirement at the time of death (for men and women) and the average pension time for men and women in public employment in Portugal.

Effects of Age-Related Cognitive Deficits on EEG Phase Coherence

Body and brain undergo several changes with aging. One of these changes is the loss of neuroplasticity, which leads to the decrease of cognitive abilities. Hence the necessity of stopping or reversing these changes is of utmost importance to contemporary society. In the present work, electroencephalogram (EEG) markers of cognitive decline are sought whilst the subjects perform the Wisconsin Card Sorting Test (WCST). Considering the expected age-related cognitive deficits, WCST was applied to young and elder participants. The results suggest that coherence on theta and alpha EEG rhythms decrease with aging and increase with performance. Additionally, theta phase coherence seems more sensitive to performance, while alpha synchronization appears as a potential ageing marker.

PERFORMANCE CAPTURE: À PROCURA DAS MELHORES TÉCNICAS E ESTÉTICAS NO CONTEXTO DA ANIMAÇÃO DIGITAL

This paper investigates realism in character computer animation, which triggered the development of new techniques and aesthetic in spectacular cinema and contemporary culture. With the advent of motion or performing capture, animation has made possible that virtual characters or digital creatures reach higher levels in emotional acting, taking place in virtual cinematic worlds or even special effects movies. This technology, when placed at the service of imagination and fantasy can provide new dimensions in character motion and communication. In this context, projects like Peter Jackson’s (2001) The Lord of the Rings, James Cameron’s Avatar (2009) and more recently Steven Spielberg’s Tintin (2011) demonstrate that motion technology is constantly evolving, and it represents a credible option to explore new techniques and aesthetic in contemporary animation.

O livro ilustrado digital e o livro ilustrado impresso

O presente estudo tem como objecto central o livro ilustrado e tem como objectivo principal compreender as diferenças entre dois modelos: o livro impresso e o livro digital. Partindo de um objecto de estudo concreto, um livro tradicional em formato impresso desenvolvido na disciplina de Ilustração no contexto do Mestrado de Ilustração e Animação do Instituto Politécnico do Cávado e do Ave, é nosso objectivo perceber as principais diferenças que ocorrem na transição para um suporte digital, especificamente num formato iPad, assim como enunciar algumas das metodologias possíveis para que esta transição seja eficaz. Num momento de transição como o que vivemos actualmente, em que o ilustrador tem cada vez mais necessidade de se adaptar a novos meios, novas ferramentas de trabalho e novas formas de comunicação, importa reflectir sobre a natureza do livro e sobre as características que distinguem os dois suportes, o tradicional e o digital. Assim, é nossa intenção perceber essas diferenças e enunciar alguns dos procedimentos que o ilustrador deve ter em conta quando experimenta a transição de um objecto de ilustração para um meio digital táctil como é o iPad.

Loneliness in Middle and Old Age

Purpose of the research: (a) To identify the degree of much loneliness reported in the Portuguese population over 50 years of age and (b) test whether loneliness can be predicted by socio-demographic, health related or social characteristic of the sample other than age. Materials and methods: 1174 late middle age and older adults were interviewed face to face by different interviewers across the country; after the informed consent was signed, we asked the participants several socio-demographic and health-related questions; finally we asked ‘‘How often do you feel lonely?’’ and participants responded according to a five point Likert scale. Principal results: The results showed that 12% of participants reporting feeling lonely often or always, whereas 40% reporting never feeling lonely. The remaining 48% self-reported they felt lonely seldom or sometimes. Additionally, results show that, when taken together, variables such as marital status, type of housing, residence settings, health conditions, social satisfaction, social isolation, lack of interest, transportation, and age were predictors of loneliness. Major conclusions: (1) The association of loneliness with advanced age has been greatly exaggerated by mass media and common sense; (2) But although our findings did not confirm the most alarmist views, the 12% of older adults reporting that they are feeling lonely always or often should be cause for attention and concern. It is necessary to understand the meaning, reasons and level of suffering implied on those feelings of loneliness. (3) Our findings suggest that it makes no sense to construe age as a singular feature or cause for feelings of loneliness. Instead, age and also a number of other features combine to predict feelings of loneliness. But even with our predictor variables there was a substantial of variance left unexplained. Therefore it is necessary to continue exploring how feelings of loneliness arise from the experience of living and how they can be changed.

O impacto da exclusão digital na utilização potencial de um mercado eletrónico de serviços de cuidados de saúde e serviços sociais

Cada vez mais os indivíduos necessitam de competências digitais avançadas para participar plenamente na sociedade. Numa Europa em crescente envelhecimento é atualmente reconhecida a importância e o potencial da indústria de serviços para envelhecer bem baseados nas tecnologias de informação e de comunicação (TIC), de que é exemplo o mercado eletrónico de serviços sociais e de cuidados de saúde, o GuiMarket, proposto pelos autores para um município do Norte de Portugal. Com base nos resultados de um inquérito realizado junto de uma amostra de 315 indivíduos, o artigo discute a importância reconhecida a tal serviço e a frequência de utilização prevista, concluindo existir uma íntima relação entre o acesso às TIC e a utilização que os inquiridos preveem fazer do GuiMarket.

The impact of the digital divide on the perceived interest of an e-Marketplace to support healthcare and social care services

In a Europe increasingly aging, it is now recognized the importance and potential of the service industry for ageing well based on information and communication technologies (ICT), as exemplified by the electronic market of social services and health care, the GuiMarket, proposed by the authors. However, this new range of services requires that individuals have advanced digital skills to fully participate in society. Based on the results of a survey made on a sample of 315 individuals, this paper discusses the importance granted GuiMarket and the intended frequency of use, concluding there is a close relationship between ICT access and use that respondents anticipate making of GuiMarket and alike services.

The impact of size and age of the company on assessing financial risk

Textiles and tourism sectors are two important sectors in Portuguese economy. Its high exposure to both internal and international economy volatility transform the companies operating in these economic sectors especially vulnerable to recent economic crises in Portugal and European Union. The objective of this paper is to evaluate and understand the impact of size and age on the financial health of textile and tourism companies, measured by economic indices. An empirical based model is proposed. Its implications are derived and tested on a sample of 4061 Portuguese companies from textile and tourism sector, during the period 2005-2009. The results conclude that age has a stronger impact on the risk of failure than size. Whereas the effect of age is generally positive regarding the financial health of the company, the effect of size is less clear and depends on the age of the company.
