- A eficácia do planejamento no processo ensino-aprendizagemPublication . Lima, Geisa Correia; Gonçalves, Sónia PedrosoA presente dissertação faz uma abordagem sobre a temática da eficácia do Planejamento no processo ensino-aprendizagem: um estudo no Instituto Estadual de Educação, Ciência e Tecnologia do Maranhão-IEMA-UP-AXIXÁ e encontra-se inserida na linha de pesquisa de Educação, do Mestrado em Gestão do Instituto Politécnico de Tomar-IPT. Tem por objetivo geral: verificar a eficácia do planejamento enquanto ferramenta essencial no processo ensino- aprendizagem. Partindo desse contexto, buscam-se bases teóricas que fundamentam o objeto de estudo. Por se tratar de uma investigação empírica, optou-se por uma pesquisa bibliográfica, exploratória e descritiva de natureza qualitativa e quantitativa, tendo em vista a melhor explicação dos fenômenos estudados. Os sujeitos envolvidos na investigação, compreendem, os gestores, professores, alunos e pais/responsáveis, os quais fizeram parte da amostra de investigação. A pesquisa foi feita em duas etapas: primeiramente de caráter quantitativo, quando se utilizou como instrumentos de pesquisas, questionários com questões estruturadas; a segunda etapa de caráter qualitativo constou de entrevistas dirigidas com perguntas previamente definidas, com o intuito de apurar mais detalhes sobre a eficácia do planejamento no processo ensino-aprendizagem. Como resultado mais geral, observou-se que o planejamento é participativo e que a escola trabalha com um novo modelo de ensino baseado na pedagogia da presença e no projeto de vida de cada aluno, modelo esse que traz em seu âmago, o desejo de uma educação melhor. A proposta dessa dissertação não significou, disponibilizar uma receita pronta para a construção de ideias em um processo de planejamento, mas buscou contribuir com a instituição pesquisada, com os leitores e com futuros investigadores acerca da temática.

- Medidas implementadas que visam combater a fraude e evasão fiscal e aduaneira em PortugalPublication . Dias, Catarina Andreia Silvares; Carreira, FranciscoA Autoridade Tributária e Aduaneira (AT) evoluiu, progressivamente, na área da tecnologia nos últimos três anos, no qual está no grupo de administrações fiscais que lidera a revolução tecnológica na cobrança de impostos, onde simplifica a relação com os contribuintes e melhora o combate à fraude e evasão fiscal. O combate à fraude e evasão fiscal revela-se uma obrigação do Estado, por uma questão de justiça. Para fazer face a este facto, a AT, através dos Planos Estratégicos nos triénios 2015/2017 e 2018/2020 implementou medidas para combater a fraude e evasão fiscal estruturando um plano de ação para aumentar a eficácia e eficiência dos impostos. Para isso, foi necessário um maior cruzamento de informação através de um vasto conjunto de obrigações declarativas e acessórias por parte de todos os agentes económicos. Face às medidas implementadas nos Planos Estratégicos da AT, foi necessário relacionar as obrigações declarativas e acessórias, a que os sujeitos passivos estão obrigados a cumprir, para se ter uma perceção do vasto conjunto de informação que é cruzada pela AT, por forma a detetar as divergências das declarações prestadas e à consequente diminuição de fraude e evasão fiscal em Portugal. O trabalho realizado pela AT é fundamental neste combate, mas não será único, e só poderá ter sucesso se for devidamente sustentado numa legislação robusta, numa educação fiscal consistente e numa ação penal eficaz.
- The phantasmatic mind and the superstitious parts of the tattooed bodyPublication . Dias, Maria do Rosário; Ferreira, Ana; Pires, Maria Calejo; Nunes, Inês; Carvalho, Maria do RosárioTattoos have presently become works of art and body accessories, serving as anchors that help to solidify a sense of Self. The present exploratory and qualitative study aimed at understanding the mental representation of the skin in tattooed individuals and the role that tattoos play as a vehicle for the projected identity of the Self. The studied sample consisted of 387 individuals from both genders (146 males and 241 females), aged 16 to 72 years with exposed tattoos, who were invited to produce two self-portraits and a written answer on whether they had experienced any form of discrimination due to their tattooed body. We then proceeded to the content analysis of the 774 collected pictorial drawings, using a grid featuring analytical categories purposely conceived for this study. The results revealed that the self-portraits drawn before the subjects were tattooed showed less body investment than those drawn afterwards. However, the mental representation of the self-portraits drawn after the subjects were tattooed showed a fragmented idea of the body - only the body part that was tattooed was pictorially represented. Additionally, they were associated to a state of happiness (e.g. smile, movement, flexibility, freedom) and to a personal valorization.
- Sub- μW Tow-Thomas Based Biquad Filter with Improved Gain for Biomedical ApplicationsPublication . Póvoa, R.; Arya, R.; Canelas, A.; Passos, F.; Martins, R.; Lourenço, N.; Horta, N.This paper presents an innovative topology of a gm-C Operational Transconductance Amplifier (OTA), with improved gain and energy-efficiency and its corresponding implementation inside a second order Tow-Thomas based filter configuration, for biomedical and healthcare applications. The proposed OTA architecture takes advantage of a current division technique, as well as the usage of a pair of cross-coupled voltage-combiners in replacement of the static current source that traditionally bias the differential pair. The circuitry proposed in this paper is described at analytical level, fully-designed at sizing level and validated at simulation level compounded by Monte Carlo results, using a standard 130 nm technology node. Both the OTA and the biquad filter architecture are compared, in terms of performance indexes, with state-of-the-art bibliography, where the potential of both is demonstrated. The designed filter operates at weak inversion and sub-threshold, being supplied by a 0.9 V source, achieving a cut-off frequency of 15 Hz, a gain of 7 dB, hence improving the input-referred noise and consuming nearly 0.55 μW.
- FUZYE: A Fuzzy C-Means Analog IC Yield Optimization using Evolutionary-based AlgorithmsPublication . Canelas, António; Póvoa, Ricardo; Martins, Ricardo; Lourenço, Nuno; Guilherme, Jorge; Carvalho, João Paulo; Horta, NunoThis paper presents fuzzy c-means-based yield estimation (FUZYE), a methodology that reduces the time impact caused by Monte Carlo (MC) simulations in the context of analog integrated circuits (ICs) yield estimation, enabling it for yield optimization with population-based algorithms, e.g., the genetic algorithm (GA). MC analysis is the most general and reliable technique for yield estimation, yet the considerable amount of time it requires has discouraged its adoption in population-based optimization tools. The proposed methodology reduces the total number of MC simulations that are required, since, at each GA generation, the population is clustered using a fuzzy c-means (FCMs) technique, and, only the representative individual (RI) from each cluster is subject to MC simulations. This paper shows that the yield for the rest of the population can be estimated based on the membership degree of FCM and RIs yield values alone. This new method was applied on two real circuit-sizing optimization problems and the obtained results were compared to the exhaustive approach, where all individuals of the population are subject to MC analysis. The FCM approach presents a reduction of 89% in the total number of MC simulations, when compared to the exhaustive MC analysis over the full population. Moreover, a k-means-based clustering algorithm was also tested and compared with the proposed FUZYE, with the latest showing an improvement up to 13% in yield estimation accuracy
- An overview on the properties of Ximenia oil used as cosmetic in AngolaPublication . Satoto, Gabriel; Fernandes, Ana Sofia; Saraiva, Nuno; Santos, Fernando; Neng, Nuno; Nogueira, José Manuel; Almeida, Tânia Santos de; Araujo, Maria EduardaXimenia (Ximenia americana L.) is a shrub, or small tree, native from Africa and spread across different continents. In Angola, the seeds oil is used by local populations, to prevent sunburn, to smooth and hydrate the skin, and to give it a pleasant color and elasticity, to prevent stretch marks, in pregnant woman, and also as hair conditioner. Herein, an oil sold in the region (LPO), and two others extracted in laboratory, from seeds collected in the same region, were investigated in terms of their composition, chemical properties, UV transmission. The three oils are similar although the LPO is more acidic, 0.48 mg KOH/g. GC-MS analysis indicated that the major components are the fatty acids, oleic (31.82%), nervonic (11.09%), ximenic (10.22%), and hexacosa-17,20,23-trienoic acids (14.59%). Long chain fatty acids, n ≥ 20, accounted for 51.1% of the total fatty acids. A thin film of the oil showed a reduction in transmittance from 200 to 300 nm. Viscosity studies of the LPO indicated that at normal temperature of skin, the oil can be spread over the skin as a thin film. At concentrations up to 10 µg/mL, the LPO is not toxic to human keratinocytes, suggesting the safety of this oil.
- Development of a platform to align education and practice: bridging academia and the profession in PortugalPublication . Costa, Filipa Alves da; Martins, Ana Paula; Veiga, Francisco; Ramalhinho, Isabel; Lobo, José Manuel Sousa; Rodrigues, Luís; Granadeiro, Luiza; Castro, Matilde; Barata, Pedro; Gomes, Perpétua; Seabra, Vítor; Caramona, Maria MargaridaLimited fitness for practice may result from a mismatch between education and practice. Aiming to meet the common interests of academics and practitioners, the Portuguese Pharmaceutical Society (PPS) developed the Education and Practice Platform (EPP). The EPP includes one representative from each pharmacy faculty, and all Councils of Speciality Boards of Practice. Brainstorming with involved parties enabled sharing of interests, concerns and identifying a common path. Aims, mission, vision and values were set. The EPP’s mission is to: act as an enabler to foster the quality and adequacy of education through sharing best practices, ultimately leading to facilitate professional integration, and to foster quality development in teaching practices with recognition for autonomy in freedom to teach and to learn. Its vision is an alignment of education and practice with the PPS’ statutes to ensure validation of the competences defined for each practice area, and compliance with international guidance. Key performance indicators (KPIs) were set. Activities developed include the creation of a national forum to discuss education and practice, development of workshops on teaching methods and pharmacy internships, enhanced representation in international events and response to global and national requests. Ongoing work focuses on the creation of a common training framework in hospital and community pharmacy practice adapted to Portugal. The EPP is a worldwide case study, encouraging the development of discussion contributing to an open climate of sharing best practices, indirectly leading to foster a better alignment between education and practice. Many of these results are so far intangible in scientific terms but worth describing.
- Large maxillary cyst decompression : two case reportsPublication . Zagalo, L.; Gomes, J.; Lesyshyn, V.; Maia, P.; Marques, J.Maxillary odontogenic cysts frequently appear as asymptomatic intra-bony inflammatory lesions, sometimes reaching largedimensions. Both clinical and anatomopathological approach must be performed in the differential diagnosis in order to eliminate oncogenic origin. The classical surgical approach for these situations is,among others and depending on the cyst type, enucleation. This can be performed with aggressive bone curettage or with physical or chemical additional treatments of the area, such as cryotherapy or Carnoy solution application. Specially in large dimension lesions or when involving noble structures, marsupialization is also an important option. It consists in the creation of a surgical opening of the pathological cavity to allow decompression and with it, shrinkage of the lesion, and consequent bone regeneration in that area. This is kept during a limited period, so that a definitive approach can be attained later with an easier surgical technique, with fewer risks and/or less morbidity for the patient. Two clinical cases of large mandibular cysts are presented. The treatment approach was made initially with surgical decompression, being the area maintained open using a plastic catheter sutured to the mucosa and programmed for future enucleation.
