O cinema como ferramenta andragógica para a terceira idade: o Projeto CINAGE

The demographics of the early 21st century in Europe point to a notorious ageing of the population of most countries. Consequently, elderly people tend to be considered a social burden for the national healthcare and social security systems and their desire to participate actively in the civic and cultural activities of their countries is ignored. The first response to demographic ageing should therefore be a change in mentalities, which is what the area of gerontology is all about. It was in this context that the European Project CINAGE - European Cinema for Active Ageing was created. It is a transnational project, promoted by Portugal, and partnered by UK, Italy and Slovenia, oriented for the creation of a cinema course for elders and directly supported by filmic tools, within an andragogical self-reflexive approach. The modules of this course will be created on the basis of European cinematic examples and the input of focus groups consisting of experts in andragogy, active ageing, cinema and elders. In the end, twelve short films will be produced by senior members of the CINAGE course. We aim to present the project CINAGE in all its characteristics and thus reveal a way in which cinema can positively contribute to a more active ageing and the maintenance of mental health in later stages of life. It is relevant to consider what films Europe has been lately producing on this subject. We will use some of them to explain and corroborate our point of view and the project itself.

PV system modeling by five parameters and in situ test

This paper focuses on a novel formalization for assessing the five parameter modeling of a photovoltaic cell. An optimization procedure is used as a feasibility problem to find the parameters tuned at the open circuit, maximum power, and short circuit points in order to assess the data needed for plotting the I-V curve. A comparison with experimental results is presented for two monocrystalline PV modules.

Modular high-current generator for electromagnetic forming with energy recovery

A 10 kJ electromagnetic forming (EMF) modulator with energy recovery based on two resonant power modules, each containing a 4.5 kV/30-kA silicon controlled rectifier, a 1.11-mF capacitor bank and an energy recovery circuit, working in parallel to allow a maximum actuator discharge current amplitude and rate of 50 kA and 2 kA/mu s was successfully developed and tested. It can be plugged in standard single phase 230 V/16 A mains socket and the circuit is able to recover up to 32% of its initial energy, reducing the charging time of conventional EMF systems by up to 68%.
