Estudo do impacte da institucionalização em lares na satisfação das necessidades humanas fundamentais : perspectiva dos idosos residentes

RESUMO O envelhecimento populacional, nos países ditos “desenvolvidos”, tem sido largamente discutido a nível internacional pelas suas implicações económicas, sociais e de saúde. Uma das prioridades de intervenção face a este fenómeno é promover o aumento de pessoas idosas autónomas inseridas no seu contexto social e familiar habitual. No entanto, nem sempre esse objectivo é atingido e a muitas pessoas idosas restam os lares, ou preferem-nos, como opção de alojamento e de satisfação das necessidades humanas fundamentais. O principal objectivo deste estudo foi procurar saber se a institucionalização no lar teve impacte na satisfação habitual das necessidades humanas fundamentais das pessoas idosas. Como objectivos secundários pretendeu-se complementar esta informação com alguns aspectos relacionados com o processo de institucionalização e perceber se existem diferenças significativas no que respeita ao sexo, grupo etário ou tempo de internamento. Foram incluídas no estudo 125 pessoas com 65 ou mais anos, residentes em 15 lares com alvará de iniciativa privada, pertencentes à Região de Lisboa e Vale do Tejo, no distrito de Setúbal. Os dados foram obtidos através de um questionário construído para o efeito pela autora. As principais conclusões do estudo apontaram para um impacte negativo da institucionalização na satisfação habitual de algumas necessidades que se enquadram no plano social, nomeadamente ocupar-se para se sentir útil, recrear-se e comunicar com os semelhantes. Nas diferentes necessidades, de uma forma geral, a institucionalização teve um impacte negativo no que respeita às dimensões relacionadas com privacidade e preferência individual. Por outro lado, a institucionalização parece ter tido um impacte positivo nas dimensões relacionadas com a segurança e a acessibilidade. Não foram encontradas diferenças significativas no que respeita ao número médio de respostas favoráveis ao lar ou à casa entre os grupos etários ou quanto ao tempo de internamento. Apesar disso, encontraram-se diferenças no que respeita ao grau de satisfação em residir num lar, sendo que o nível de satisfação com a institucionalização foi maior nas pessoas que residiam no lar há mais de um ano, comparativamente às que residiam no lar há um ano ou menos.-------------------------------------------- ABSTRACT: The ageing of the population of the more developed countries has been largely discussed internationally because of its economic, social and health implications. One of the priorities of intervention facing the ageing phenomenon is to promote the increase of autonomous elderly, within their usual social and familiar environment. Not always this goal is achieved and many elderly have nursing homes as option, or voluntary choose them, for lodgement and fundamental human needs satisfaction. The main goal of this study was to search whether the nursing home institutionalization had impact in the satisfaction of fundamental human needs. As secondary goals it was established to complement this information with some aspects of the institutionalization process, as well as to analyse if there were significant differences as far as sex, age groups or institutionalization time. The study sample included 125 individuals aged 65 years or more, living in 15 private nursing homes with approved legal certification, belonging to the Lisboa and Tagus Valley Region, in the district of Setúbal. Data were collected through a questionnaire designed for this study by the author. The main conclusions of this study pointed at a negative impact of institutionalization on the usual satisfaction of some human needs included at the social field, namely occupation, recreation and communication. At another level of needs, in a general way, institutionalization had negative impact concerning privacy and individual preferences dimensions. On the other hand, institutionalization appeared to have a positive impact in safety and accessibility dimensions. It was not found significant differences between age groups or institutionalization time as far as the average positive answers in favour to nursing home or house. Notwithstanding, there were differences relating to satisfaction in living at the nursing home being the satisfaction higher in residents who lived at the nursing home for more than a year, comparatively to those that lived at the nursing home for a year or less.

Cloud-assisted Wireless Body Area Networks

Wireless Body Area Networks (WBANs) have emerged as a promising technology for medical and non-medical applications. WBANs consist of a number of miniaturized, portable, and autonomous sensor nodes that are used for long-term health monitoring of patients. These sensor nodes continuously collect information of patients, which are used for ubiquitous health monitoring. In addition, WBANs may be used for managing catastrophic events and increasing the effectiveness and performance of rescue forces. The huge amount of data collected by WBAN nodes demands scalable, on-demand, powerful, and secure storage and processing infrastructure. Cloud computing is expected to play a significant role in achieving the aforementioned objectives. The cloud computing environment links different devices ranging from miniaturized sensor nodes to high-performance supercomputers for delivering people-centric and context-centric services to the individuals and industries. The possible integration of WBANs with cloud computing (WBAN-cloud) will introduce viable and hybrid platform that must be able to process the huge amount of data collected from multiple WBANs. This WBAN-cloud will enable users (including physicians and nurses) to globally access the processing and storage infrastructure at competitive costs. Because WBANs forward useful and life-critical information to the cloud – which may operate in distributed and hostile environments, novel security mechanisms are required to prevent malicious interactions to the storage infrastructure. Both the cloud providers and the users must take strong security measures to protect the storage infrastructure.

Spectral invariants of periodic nonautonomous discrete dynamical systems

For an interval map, the poles of the Artin-Mazur zeta function provide topological invariants which are closely connected to topological entropy. It is known that for a time-periodic nonautonomous dynamical system F with period p, the p-th power [zeta(F) (z)](p) of its zeta function is meromorphic in the unit disk. Unlike in the autonomous case, where the zeta function zeta(f)(z) only has poles in the unit disk, in the p-periodic nonautonomous case [zeta(F)(z)](p) may have zeros. In this paper we introduce the concept of spectral invariants of p-periodic nonautonomous discrete dynamical systems and study the role played by the zeros of [zeta(F)(z)](p) in this context. As we will see, these zeros play an important role in the spectral classification of these systems.

Group-to-group bidirectional Wi-Fi direct communication with two relay nodes

The current capabilities of mobile phones in terms of communication, processing and storage, enables its use to form autonomous networks of devices that can be used in case of collapse or inexistent support from a communication infrastructure. In this paper, we propose a network configuration of nodes that provides high-speed bidirectional device-to-device communication, with symmetrical data transfer rates, in Wi-Fi Direct multi-group scenarios, without using performance hindering broadcasts.

Complementary filter design with three frequency bands: robot attitude estimation

This paper extents the by now classic sensor fusion complementary filter (CF) design, involving two sensors, to the case where three sensors that provide measurements in different bands are available. This paper shows that the use of classical CF techniques to tackle a generic three sensors fusion problem, based solely on their frequency domain characteristics, leads to a minimal realization, stable, sub-optimal solution, denoted as Complementary Filters3 (CF3). Then, a new approach for the estimation problem at hand is used, based on optimal linear Kalman filtering techniques. Moreover, the solution is shown to preserve the complementary property, i.e. the sum of the three transfer functions of the respective sensors add up to one, both in continuous and discrete time domains. This new class of filters are denoted as Complementary Kalman Filters3 (CKF3). The attitude estimation of a mobile robot is addressed, based on data from a rate gyroscope, a digital compass, and odometry. The experimental results obtained are reported.

Multi-agent management system for electric vehicle charging

This paper proposes an implementation, based on a multi-agent system, of a management system for automated negotiation of electricity allocation for charging electric vehicles (EVs) and simulates its performance. The widespread existence of charging infrastructures capable of autonomous operation is recognised as a major driver towards the mass adoption of EVs by mobility consumers. Eventually, conflicting requirements from both power grid and EV owners require automated middleman aggregator agents to intermediate all operations, for example, bidding and negotiation, between these parts. Multi-agent systems are designed to provide distributed, modular, coordinated and collaborative management systems; therefore, they seem suitable to address the management of such complex charging infrastructures. Our solution consists in the implementation of virtual agents to be integrated into the management software of a charging infrastructure. We start by modelling the multi-agent architecture using a federated, hierarchical layers setup and as well as the agents' behaviours and interactions. Each of these layers comprises several components, for example, data bases, decision-making and auction mechanisms. The implementation of multi-agent platform and auctions rules, and of models for battery dynamics, is also addressed. Four scenarios were predefined to assess the management system performance under real usage conditions, considering different types of profiles for EVs owners', different infrastructure configurations and usage and different loads on the utility grid (where real data from the concession holder of the Portuguese electricity transmission grid is used). Simulations carried with the four scenarios validate the performance of the modelled system while complying with all the requirements. Although all of these have been performed for one charging station alone, a multi-agent design may in the future be used for the higher level problem of distributing energy among charging stations.

CMOS indoor light energy harvesting system for wireless sensing applications

This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system. © 2016 Springer International Publishing.

The most Portuguese village in Portugal: tradition in the age of its technical reproducibility

Ethnographic film is often associated with many European countries’ past as colonial powers and the way these countries used film to depict African, American and Asian territories and populations they once ruled. However, ethnographic film also has a European tradition of its own, closely interlaced with the history of ethnography and anthropology as autonomous sciences and with the desire of scholars to represent local, regional and national cultural identities. This paper presents a Portuguese attempt of this sort dating from 1938, when the authoritarian regime organized a national contest to determine which would be Portugal’s most “authentic” village – something other European countries also did. As part of this metonymic contribution to the construction of Portugal’s national identity as an agrarian utopia, a short documentary was shot, sponsored by the same official propaganda office that had organized the contest. In this film, the viewer’s gaze is made to coincide with the one of the national jury visiting the final selection of 12 villages and to whose benefit local scholars had organized all sorts of colourful peasant traditions hoping to cause the strongest impression. The film makes a strong case for the importance of ethnographic film as a relevant instance not only of the iteration of existing European national cultures, but also of the construction of so many of Europe’s national identities and traditions. Suffice to say that even today the village of “Monsanto”, which won the 1938 contest, is still referred to as “Portugal’s most Portuguese village”.
