O processo de envelhecimento numa população adulta com défice intelectual e desenvolvimental, DID: "perfil de funcionalidade"

RESUMO: O envelhecimento demográfico da população associado aos avanços científicos fezcom que esse fenómeno se estendesse à população com dificuldade intelectual e desenvolvimental. O processo de envelhecimento na população com DID acarreta novas formas de dependência, carências e perdas que, associadas à deficiência assumem contornos de dupla vulnerabilidade: ser idoso e ser deficiente. Objetivos, deste estudo foram caraterizar o perfil de funcionalidade numa população adulta com DID e apurar de que forma é que os aspectos sociodemográficos, condição de saúde, estado nutricional e redes socias de apoio interferem nesse perfil. Metodologia, aplicou-se a Escala de Comportamento Adaptativo versão Portuguesa a uma amostra de 40 indivíduos com DID, procedeu-se ao estudo da relação entre os vários domínios da escala e os diferentes aspetos anteriormente mencionados. Resultados, apontam para o facto, de tal como na população em geral, o processo de envelhecimento desta população variar em função do estado de saúde, das limitações da própria deficiência e da existência de sistema de apoios mais do que a idade cronológica. Conclusão, o envelhecimento da população com DID é um fenómeno recente sendo por isso importante ter um conhecimento mais aprofundado das suas caraterísticas e necessidades. A ECAP revelou ser um instrumento que permite avaliar o desempenho funcional desta população distinguindo-a da restante população idosa contribuindo assim, para o desenvolvimento de planos e programas de intervenção mais adequados.-------------ABSTRACT: The aging of the population associated with scientific advances made this phenomenon extend to the population with intellectual and developmental difficulties. The aging process in people with DID entails new forms of dependence, shortages and losses, associated with disability take contours of double vulnerability: being elderly and being disabled. Objectives, in this study were to characterize the profile functionality in an adult population with DID and determine how it is that their sociodemographic characteristics, health status, nutritional status and members support networks affect this listing. Methodology, was applied the adaptive behavior scale Portuguese version to a sample of 40 individuals with DID, we proceeded to study the relationship between the various domains of the scale and the different aspects mentioned above. Results, point to the fact, such as in the general population, the aging of the population vary depending on the state of health, of the limitations of the disability itself and the existence of support rather than chronological age system. Conclusion, an aging population with DID is a recent phenomenon and is therefore important to have a broader knowledge of their characteristics and needs. ECAP has proved to be a tool to evaluate the functional performance of this population distinguished from the remaining elderly population, thus contributing to the development of plans and most appropriate intervention programs. aging, adaptive behavior scale.

Implementation of a pilot project for the treatment and prevention of substance abuse in children and adolescents : strengthening families for parents and youths 12-16

RESUMO: Antecendentes: Uma avaliação dos serviços de abuso de substâncias em Barbados identificou a necessidade de programas e serviços que são projetados especificamente para crianças e adolescentes. Objetivo: Realizar programa com base em evidências para reduzir a incidência de abuso de drogas entre crianças e adolescentes por meio do fortalecimento da unidade familiar através de parentalidade positiva, de maior funcionamento familiar e de resistência dos jovens. Método: Dois projetos-piloto foram realizadas com base no programa "Fortalecer as Famílias para Pais e Jovens de 12 a 16 anos (SFPY). O programa de nove semanas foi empregado como uma intervenção para criar laços familiares mais fortes, aumentar a resistência dos jovens e reduzir o abuso de drogas entre crianças e adolescentes de idades de 11 a 16 anos. A decisão foi tomada para incluir participantes de 11 anos desde que as crianças possam estar no primeiro ano da escola secundária nessa idade. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 5 Resultados: Quinze famílias participaram em dois projetos-piloto e a avaliação final mostrou que os jovens após o programa, geralmente tornaram-se mais positivos sobre o seu lugar na unidade familiar e sentiram que sua participação no programa foi benéfica. Os pais, da mesma forma, relataram que eles conquistaram, com o programa uma relação mais positiva, uma melhor compreensão das necessidades, e consciência das mudanças de desenvolvimento de seus jovens. Desta forma, considera-se que o programa atingiu o resultado desejado de criar unidades familiares mais fortes. Conclusão: O Projeto Piloto “SFPY” foi bem sucedido em fazer pais e jovens mais conscientes de suas necessidades individuais e de responsabilidades dentro da unidade familiar. Como resultado, o relacionamentos das respectivas famílias melhorou. Estudos baseados em evidências têm demonstrado que um relação familiar mais forte diminui a incidência de uso e abuso de drogas na população adolescente, aumentando os fatores de proteção e diminuindo os fatores de risco. A implementação do programa, que foi desenvolvido e testado no ambiente norte-americano, demonstrou que era transferível para a sociedade de Barbados. No entanto, seu impacto total só pode ser determinado através de um estudo comparativo envolvendo um grupo de controle e / ou uma intervenção alternativa ao abuso de substâncias. Portanto, é recomendável que um estudo comparativo da intervenção SFPY deve envolver uma amostra representativa de adolescentes que estão em estágio de desenvolvimento anterior mais cedo. Evidências já demonstram que o programa é mais eficaz, com impacto mais longo sobre os jovens que participam em uma idade maisABSTRACT:Background: An evaluation of substance abuse services in Barbados has identified the need for programmes and services that are specifically designed for children and adolescents. Aim: To conduct an evidence-based programme to reduce the incidence of substance abuse among children and adolescents by strengthening the family unit through positive parenting, enhanced family functioning and youth resilience. Method: Two pilot projects were conducted based on the ‘Strengthening Families for Parents and Youths 12– 16’ (SFPY) programme. The nine-week programme was employed as an intervention to create stronger family connections, increase youth resiliency and reduce drug abuse among children and adolescents between the ages of 11 to 16. The decision was made to include participants from age 11 since children may be in the first year of secondary school at this age. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 3 Results: Fifteen families participated in two pilot projects and an evaluation conducted at the conclusion showed that the youth were generally more positive about their perceived place in the family unit and felt that the being in the programme was generally beneficial. The parents similarly reported they had a more positive relationship with their youths and also had a better understanding of their needs, and an awareness of their developmental changes. This affirmed that the programme had achieved its desired outcome to create stronger family units. Conclusion: The SFPY Pilot Project was successful in making parents and youths more aware of their individual needs and responsibilities within the family unit. As a result relationships within their respective families were strengthened. Evidence-based studies have shown that enhanced family functioning decreases the incidence of substance use and abuse in the adolescent population by increasing protective factors and decreasing risk factors. The implementation of the programme, which was developed and tested in the North American environment, demonstrated that it was transferable to the Barbadian society. However, its full impact can only be determined through a comparative study involving a control group and/or an alternative substance abuse intervention. It is therefore recommended that a comparative study of the SFPY intervention should be delivered to a representative sample of adolescents who are at an earlier developmental stage. Evidence has shown that the programme is more effective, with longer impact on youths who participate at a younger age.

Gas gap heat switch for CryoFree project

Cryogen-free superconducting magnet systems have become popular during the last two decades for the simple reason that with the use of liquid helium is rather cumbersome and is a scarce resource. Some available CFMS uses a mechanical cryocooler as cold source of the superconductor magnet. However, the cooling of the sample holder is still made through an open circuit of helium. A thermal management of a completely cryogen-free system is possible to be implemented by using a controlled gas gap heat switch (GGHS) between the cryocooler and the variable temperature insert (VTI). This way it would eliminate the helium open circuit. Heat switches are devices that allow to toggle between two distinct thermal states (ON and OFF state). Several cryogenic applications need good thermal contact and a good thermal insulation at different stages of operation. A versatile GGHS was designed and built with a 100 mm gap and tested with helium as exchange gas. An analytic thermal model was developed and a good agreement with the experimental data was obtained. The device was tested on a crycooler at 4 to 80 K ranges. A 285 mW/K thermal conductance was measured at ON state and 0.09 mW/K at OFF. 3000 ON/OFF thermal conductance ratio was obtained at 4 K with helium.

How enterprise 2,0 firms take advantage of emergent social software platforms to manage knowledge

This research aims to provide a better understanding on how firms stimulate knowledge sharing through the utilization of collaboration tools, in particular Emergent Social Software Platforms (ESSPs). It focuses on the distinctive applications of ESSPs and on the initiatives contributing to maximize its advantages. In the first part of the research, I have itemized all types of existing collaboration tools and classify them in different categories according to their capabilities, objectives and according to their faculty for promoting knowledge sharing. In the second part, and based on an exploratory case study at Cisco Systems, I have identified the main applications of an existing enterprise social software platform named Webex Social. By combining a qualitative and quantitative approach, as well as combining data collected from survey’s results and from the analysis of the company’s documents, I am expecting to maximize the outcome of this investigation and reduce the risk of bias. Although effects cannot be universalized based on one single case study, some utilization patterns have been underlined from the data collected and potential trends in managing knowledge have been observed. The results of the research have also enabled identifying most of the constraints experienced by the users of the firm’s social software platform. Utterly, this research should provide a primary framework for firms planning to create or implement a social software platform and for firms willing to increase adoption levels and to promote the overall participation of users. It highlights the common traps that should be avoided by developers when designing a social software platform and the capabilities that it should inherently carry to support an effective knowledge management strategy.

Standardization of project management processes

Software development is a discipline that is almost as old as the history of computers. With the advent of the Internet and all of its related technologies, software development has been on high demand. But, and especially in SME (small and medium enterprise), this was not accompanied with a comparable effort to develop a set of sustainable and standardized activities of project management, which lead to increasing inefficiencies and costs. Given the actual economic situation, it makes sense to engage in an effort to reduce said inefficiencies and rising costs. For that end, this work will analyze the current state of software development’s project management processes on a Portuguese SME, along with its problems and inefficiencies in an effort to create a standardized model to manage software development, with special attention given to critical success factors in an agile software development environment, while using the best practices in process modeling. This work also aims to create guidelines to correctly integrate these changes in the existing IS structure of a company.

Double-walled PLLA/PLGA particles for the sustained release of Meloxicam: preparation, characterisation and contolled release studies

There were two main objectives in this thesis investigation, first, the production, characterisation, in vitro degradation and release studies of double walled microspheres for drug release control. The second one, and the most challenging, was the production of double walled nanospheres, also for drug control delivery. The spheres were produced using two polymers, the Poly(L-lactide)Acid, PLLA, and the Poly(L-lactide-co-glycolic)Acid, PLGA.Afterwards, a model drug, Meloxicam, which is an antiinflammatory drug, was encapsulated into the particles. Micro and nanospheres were produced by the solvent extraction/evaporation method, where perfect spherical particles were obtained. By varying the polymers PLLA/PLGA mass ratio, different core and shell composition, as well as several shell and core thickness were observed. In the particles with a PLLA/PLGA mass ratio 1:1, the shell is composed by PLLA and the core by PLGA. It was also verified that the Meloxicam has a tendency to be distributed in the PLGA layer. Micro and nanoparticles were characterised in morphology, size, polymer cristalinity properties and drug distribution. Particles degradation studies was performed, where the particles in a PVA solution of pH 7,4 where placed in an incubator, during approximately 40 days, at 120rpm, and 37ºC, simulating, as much as possible, the human body environment. From these studies, the conclusion was that particles containing a PLGA shell and a PLLA core degrade more rapidly, due to the fact that PLLA is more hydrophobic than the PLGA. Concerning the drug release controlled results, done also for 40 and 50 days, they showed that the microspheres containing a shell of PLLA release more slowly than when the shell is composed of PLGA. This result was predictable, since the drug is solubilised in the PLGA polymer and so, in that case, the PLLA shell works like a barrier between the drug and the outer medium. Another positive aspect presented by this study is the lower initial burst effect, obtained when using double walled particles, which is one of the advantages of the same. In a second part of this investigation, the production of the nanospheres was the main goal, since it was not yet accomplished by other authors or investigators. After several studies, referring to the speed, time and type of agitation, as well as, the concentration and volume of the first aqueous solution of poly-vinyl-alcohol (PVA) during the process of solvent extraction/evaporation it was possible to obtain double walled nanospheres.(...)

Context-based identification of energy consumption in industrial plants

Nowadays, reducing energy consumption is one of the highest priorities and biggest challenges faced worldwide and in particular in the industrial sector. Given the increasing trend of consumption and the current economical crisis, identifying cost reductions on the most energy-intensive sectors has become one of the main concerns among companies and researchers. Particularly in industrial environments, energy consumption is affected by several factors, namely production factors(e.g. equipments), human (e.g. operators experience), environmental (e.g. temperature), among others, which influence the way of how energy is used across the plant. Therefore, several approaches for identifying consumption causes have been suggested and discussed. However, the existing methods only provide guidelines for energy consumption and have shown difficulties in explaining certain energy consumption patterns due to the lack of structure to incorporate context influence, hence are not able to track down the causes of consumption to a process level, where optimization measures can actually take place. This dissertation proposes a new approach to tackle this issue, by on-line estimation of context-based energy consumption models, which are able to map operating context to consumption patterns. Context identification is performed by regression tree algorithms. Energy consumption estimation is achieved by means of a multi-model architecture using multiple RLS algorithms, locally estimated for each operating context. Lastly, the proposed approach is applied to a real cement plant grinding circuit. Experimental results prove the viability of the overall system, regarding both automatic context identification and energy consumption estimation.
