Towards patient-specific carbohydrate counting accuracy : an in silico study
Get PDFType 1 diabetes mellitus patients on intensive insulin therapy use advanced carbohydrate counting to proper dose prandial insulin. Therefore, the patient’s ability to accurately estimate the meal’s carbohydrate content is paramount. However, despite its significance, several studies show that the patient’s ability to estimates the meal’s carbohydrate content is far from ideal and identify the need for continuous education on carbohydrate counting. In this context, the authors have proposed in previous
works an analytic method to determine the maximum error to the carbohydrate counting regarding each patient’s insulin-to-carb ratio and the insulin sensitivity factor. This maximum can be of great significance to design patient-specific educational programs and to define learning outcomes according to the specific characteristics of each patient. This work presents a methodology and conditions to assess the previously proposed method, using the FDA-approved University of Virginia(UVA)/Padova Type 1

Identification of students' multiple achievement and social goal profiles and analysis of their stability and adaptability
Get PDFThe present study moves to a more comprehensive understanding of the dynamics of student's goal orientation by jointly analyzing a variety of students' achievement goals together with students' social goals, and their combined effects. Using a person-centered approach (latent cluster analysis) the study identified students' (N = 386) goal profiles, analysed in what ways achievement and social goals are combined, and tested whether profile groups differed on their motivational and academic adaptability. Moreover, this study analysed stability and change in students' multiple goal profiles across the transition into secondary school (from 9th to 10th grade). Six distinct profiles of achievement and social goals emerged showing construct stability over time. Across profiles findings showed that prosocial and social responsibility goals are connected with mastery goals, but seem more difficult to reconcile with performance-competitive goals. In general, findings highlighted the positive role of both mastery and social goals in students' academic outcomes (differences between profiles ranging from η 2 0.03 to 0.18), but also showed that distinct goal combinations may be compatible with students' motivation and academic success.8C1E-AFB9-6BE1 | Maria Teresa Martins GonçalvesN/
Perceived impacts of running events in protected areas : the case of trans Peneda-Gerês at Peneda Gerês National Park, Portugal
No full textThis chapter reflects upon the reality associated with running sports events in protected areas, in particular at the Peneda Gerês National Park (PNPG), with a particular focus on the Trans Peneda-Gerês (TPG), and understands its impacts within a sustainable tourism development perspective. With the diversity of landscapes and natural resources, and its characteristic villages, PNPG, as many other protected areas in Portugal, has a strong potential for Outdoor Sports/Tourism, offering some of Portugal’s best running trails. As such, a considerable number of running events are currently being hosted. Based on a research process which includes both questionnaires and interviews, the authors propose to identify the profile and behavior of 2019 TPG edition’s participants, and to assess local stakeholders’ perception of economic, environmental, and social impacts, and to contribute to the discussion from a sustainable development perspective of the creation and management of tourism-related sports events, namely running, in protected areas.B913-0565-0908 | Elvira Vieirainfo:eu-repo/semantics/publishedVersio
Processing and electrical conductivity of lanthanum gallate core-shell heterostructures
Get PDFThe electrical properties of a lanthanum gallate solid electrolyte were modified by selectively doping the grain boundaries with Fe. This was achieved by sandwiching a La0.95Sr0.05Ga0.90Mg0.10O3-δ
(LSGM) dense pellet between LaFeO3 samples. Annealing at 1550°C in air for several hours promoted Fe diffusion into LSGM via the grain boundaries. Scanning electron microscopy and energy-dispersive spectroscopy analyses showed that iron was located at the grain boundary while the grain bulk preserved the LSGM composition. Impedance spectra obtained at low temperature consist of the two usual bulk and grain boundary contributions. A significant increase in total conductivity was observed for the iron-doped samples, the effect being greater for the grain boundary contribution. The total conductivity measured for the iron-containing material revealed a slight decrease with decreasing oxygen partial pressure, suggesting the onset of p-type electronic conduction. Estimates of the p-type electronic conductivity (σp) were obtained by fitting the low temperature impedance spectra to a simple equivalent circuit including one parallel electronic branch. The value for σp in air at 300°C is 3.1×10-6 S/cm and the activation energy is 75.1 kJ/mol between 300 and 400°C.371C-9F16-EBDE | Eduarda GomesN/
Joining sustainable design and internet of things technologies on campus : the IPVC smartbottle practical case
Get PDFHigher education institutions (HEIs) are favored environments for the implementation of technological solutions that accelerate the generation of smart campi, given the dynamic ecosystem they create based on the involvement of inspired and motivated human resources (students, professors, and researchers), moving around in an atmosphere of advanced digital infrastructures and services. Moreover, HEIs have, in their mission, not only the creation of integrated knowledge through Research and Development (R&D) activities but also solving societal problems that address the academic community expectations concerning environmental issues, contributing, therefore, towards a greener society embodied within the United Nations (UN) Sustainable Development Goals (SDGs). This article addresses the design and implementation of a Smartbottle Ecosystem in which an interactive and reusable water bottle communicates with an intelligent water refill station, both integrated by the Internet of Things (IoT) and Information and Communications Technologies (ICT), to eliminate the use of single-use plastic water bottles in the premises of the Polytechnical Institute of Viana do Castelo (IPVC), an HEI with nearly 6000 students. Three main contributions were identified in this research: (i) the proposal of a novel methodology based on the association of Design Thinking and Participatory Design as the basis for Sustainable Design; (ii) the design and development of an IoT-enabled smartbottle prototype; and (iii) the usability evaluation of the proposed prototype. The adopted methodology is rooted in Design Thinking and mixes it with a Participatory Design approach, including the end-user opinion throughout the Smartbottle Ecosystem design process, not only for the product design requirements but also for its specification. By promoting a participatory solution tailored to the IPVC academic community, recycled plastic has been identified as the preferential material and a marine mammal was selected for the smartbottle shape, in the process of developing a solution to replace the single-use plastic bottles.7519-C505-DF9E | António José Candeias CuradoN/
Grain boundary Fe-doping effects in LSGM
Get PDFThe electrical properties of La0.95Sr0.05Ga0.90Mg0.10O3 − δ (LSGM) were modified by selective doping of the grain boundaries, using LaFeO3
screen-printed layers and annealing at high temperature to promote Fe diffusion into LSGM. Scanning electron microscopy (SEM) and energydispersive spectroscopy (EDS) analyses showed that iron was mainly located along the grain boundaries with the bulk grain composition almost
unchanged. Impedance spectra showed a significant increase in the total conductivity for the Fe-doped samples, the effect being greater for the
grain boundary contribution. The formation of a parallel pathway for electronic conduction along the grain boundaries explains these effects.
Ageing of these samples at high temperature, after removal of the Fe source, showed a steady shift to the original LSGM behaviour, due to dilution
of Fe throughout the samples.371C-9F16-EBDE | Eduarda GomesN/
A gestão terapêutica e a segurança do doente no Bloco Operatório
Get PDFRelatório de Estágio de Natureza Profissional no âmbito do Mestrado em Enfermagem Médico-Cirúrgica apresentada na Escola Superior de Saúde do Instituto Politécnico de Viana do CasteloO presente relatório, descreve, analisa e reflete o processo de desenvolvimento e aquisição de competências especializadas, na área da pessoa em situação critica, adquiridas ao longo da Unidade Curricular - Estágio de Natureza Profissional (ENP), realizado no âmbito do Mestrado em Enfermagem Médico-Cirúrgica.
Neste sentido, o ENP, decorreu no Bloco Operatório Central (BO) do Centro Hospitalar Póvoa de Varzim / Vila do Conde de 11 de janeiro a 11 de julho de 2021, tendo como principal objetivo o desenvolvimento de competências comuns e especificas em Enfermagem Médico-Cirúrgica, na área da prestação de cuidados à pessoa em situação crítica no BO. Para o desenvolvimento e aquisição destas competências, emergiram diversas atividades no contexto de estágio que foram realizadas com sustentação em bases teóricas e na evidência científica, de modo a garantir uma melhoria da qualidade dos cuidados e a excelência no exercício da profissão. Desta experiência, não é de mais descrever, a importância do papel do enfermeiro especialista em médico-cirúrgica no BO no cuidar ao doente crítico pela sua diferenciação na prestação de cuidados. No que diz respeito ao nosso desempenho neste estágio, destacamos o papel da formação profissional em enfermagem no desenvolvimento de competências, a aprendizagem e reflexão sobre as práticas no cuidar ao doente em situação crítica no BO e no conhecimento do agir em ambientes imprevisíveis e instáveis.
No âmbito da investigação, recorremos a uma revisão integrativa da literatura, para dar resposta à problemática, a gestão terapêutica e a segurança do doente no Bloco Operatório.
A pertinência do tema, decorre pela necessidade de cada vez mais se promover a cultura de segurança do doente, uma vez que é requisito essencial à qualidade dos cuidados de saúde e também pela minimização dos erros associados à terapêutica da enfermagem de anestesia, visto que estes podem desencadear um agravamento da situação do doente.
Como principal resultado deste trabalho de investigação foram implementados novos procedimentos de enfermagem no Bloco Operatório. Estes, incidiram na rotulagem dos medicamentos de acordo com os medicamentos Look Alike e Sound Alike, medicamentos de Alto Risco e rotulagem com recurso a codificação por cores.
A aprendizagem não é estanque, pelo que procuramos, enquanto futura Enfermeira Especialista, a melhoria contínua cuidados prestados com qualidade, eficácia e humanização dos mesmos.This report describes, analyzes and reflects the process of development and acquisition of specialized skills, in the area of the person in a critical situation, acquired throughout the Curricular Unit - Internship of a Professional Nature, carried out within the scope of the Master in Medical-Surgical Nursing.
In this sense, the internship of a professional nature took place in the Operation Room of the Centro Hospitalar Póvoa de Varzim / Vila do Conde from January 11 to July 11, 2021, with the main objective of developing common and specific skills medical-surgical nursing, in the area of providing care to the person in critical condition in the Operation Room. For the development and acquisition of these skills, several activities emerged in the internship context that were carried out in a way based on theoretical bases and scientific evidence, in order to guarantee an improvement in the quality of care and excellence in the exercise of the profession. From this experience, it is not enough to describe the importance of the role of the medical-surgical nurse specialist in the Operation Room in caring for the critically ill patient due to their differentiation in the provision of care. With regard to our performance in this internship, we highlight the role of professional training in nursing in the development of skills, learning and reflection on practices in caring for the patient in a critical situation in the Operation Room and in the knowledge of acting in unpredictable and unstable environments.
Within the scope of the investigation, we resorted to an integrative literature review, to respond to the problem, therapeutic management and patient safety in the Operation Room: contributions from anesthesia nursing.
The relevance of the topic stems from the need to increasingly promote a patient safety culture, since it is an essential requirement for the quality of health care and due to the minimization of errors associated with anesthesia nursing therapy.
As the main result of this investigation, new nursing procedures were implemented in the Operation Room. These were nothing more and nothing less than the labeling of medicines according to Look Alike and Sound Alike medicines, High Risk medicines and labeling using color coding.
Learning is not watertight, so I seek, as a Specialist Nurse, the continuous improvement of care provided with quality, effectiveness and humanization
Molecular detection of Rickettsia spp. in ticks and fleas collected from rescued hedgehogs (Erinaceus europaeus) in Portugal.
Get PDFHedgehogs (e.g., Erinaceus europaeus, E. roumanicus) are wild mammals that frequently
are observed near residential areas. The aim of this study was to investigate ticks and feas
collected from European hedgehogs in Portugal and to evaluate the prevalence of Rickettsia in those ectoparasites. Ticks and feas were identifed by morphological and molecular
methods, and molecular detection by PCR and genotypic characterization of Rickettsia spp.
was performed targeting ompB, ompA and gltA gene fragments. In total, 1892 ticks and
213 feas were collected from 33 rescued European hedgehogs captured in seven districts
of the north and centre of Portugal. Two tick species were identifed – Rhipicephalus sanguineus accounted for 91% (n=1719) of the total ticks collected and 9% (n=173) were
Ixodes hexagonus. All feas were identifed as Archaeopsylla erinacei. Regarding pathogen
detection, Rickettsia massiliae DNA was found in 22 of the 212 tested Rh. sanguineus.
None of the 48 I. hexagonus tested showed to be positive for rickettsiae. Rickettsia asembonensis DNA was identifed in 55 A. erinacei feas tested (n=117). These results show
that European hedgehogs are exposed to R. massiliae transmitted by ticks and to R. asembonensis via feas suggesting that these mammals might be involved in the natural transmission cycle of these Rickettsia species. This study is the frst report of R. asembonensis
in feas in Portugal.A91F-E8B8-FA62 | Teresa Susana Letra MateusN/
The mediating role of brand experience in a mid-sized city
No full textIncreasing the attractiveness of mid-sized cities is a cross-cutting challenge within the context of the European Union, and specifically for Portugal. In this sense, we evaluate the mediating effect of brand experience between the brand personality and brand attitude applied to the city of Guimarães. A survey was conducted to the tourists and 234 useable answers were collected. Results indicate that the tourists only perceive the sincerity inside the destination brand personality dimension and this influences the brand experience and consequently affects brand attitude. The mediator effect was also verified. A destination with these characteristics must create a familiar and happy environment. It should promote good experiences in terms of, feelings, emotions and positive thinking that will influence the brand attitude. Hence, the tourists will give a good feedback with their experience and could increase their loyalty towards the destination, thus increasing the probability of repeating the visit and recommending the city.B913-0565-0908 | Elvira Vieirainfo:eu-repo/semantics/publishedVersio
Mathematical trails in teacher training
No full textEste artigo tem por base o texto da conferência proferida no VIII CIBEM, em Madrid 2017A sala de aula é uma das “casas” onde a educação tem lugar. O recurso a contextos não formais de ensino e aprendizagem, como seja o meio envolvente, constitui-se como um ambiente educativo que pode promover atitudes positivas e uma motivação adicional para o estudo da matemática. Assim, surgem os trilhos matemáticos, que consistem numa sequência de paragens com tarefas que os alunos têm de resolver, ao longo de um percurso pré-planeado. Os trilhos proporcionam experiências de aprendizagem significativas para qualquer conceito do currículo, permitindo criar um espaço informal de aprendizagem, fora da sala de aula. É fundamental que os professores contactem com abordagens desta natureza e que conheçam as suas potencialidades. Os trilhos matemáticos constituem-se particularmente com grande
potencial para a formulação de problemas por parte dos (futuros) professores e para a resolução de problemas por parte dos alunos que vivenciam os trilhos. Este artigo descreve parte de um estudo onde se pretende compreender as potencialidades dos trilhos matemáticos no âmbito da formação inicial de professores do ensino básico (3-12 anos), assim como a sua reação. Em particular, procurámos compreender como os trilhos matemáticos podem constituir-se num recurso para a formação de professores, enfatizando a formulação de problemas bem como a criatividade matemática. Adotou-se uma metodologia de natureza qualitativa e interpretativa, sendo os dados recolhidos através de observações, questionário, entrevistas e produções escritas de tarefas/trilhos. Os resultados mostram uma grande
motivação e adesão à proposta de elaboração de um trilho, com grandes potencialidades para a aprendizagem da matemática, contribuindo para aplicarem os seus conhecimentos matemáticos e
adquirir uma nova visão da matemática. Contudo estes estudantes reconhecem que formular problemas é mais complexo do que resolver problemas. ABSTRACT: The classroom is one of the “homes” where education takes place. The use of non-formal teaching and learning contexts, such as the environment, constitutes an educational environment that can promote positive attitudes and additional motivation for the study of mathematics. In this scope we have the mathematical trails, which consist of a sequence of stops with tasks that students have to solve, along a pre-planned route. The trails provide meaningful learning experiences for any concept in the curriculum, allowing the teachers to create an informal learning space, outside the classroom. It is essential that teachers contact with approaches of this nature and know their potential. The mathematical trails have particularly great potential for problem posing on the part of (future) teachers and for the problem solving on the part of the students who experience the trails. This article describes part of a study in which it is intended to understand the potential of mathematical trails in the context of elementary education teacher training (3-12 years), as well as the future teachers’ reaction. In particular, we tried to understand how mathematical trails can be a resource for teacher training, emphasizing problem posing as well as mathematical creativity. A qualitative and interpretative methodology was adopted, with data collected through observations, questionnaires, interviews and written production of tasks/trails. The results show a great motivation and involvement in the proposal to develop a trail, with great potential for learning mathematics. However, these students recognized that posing problems is more complex than solving problems, as had difficulties diversifying the content involved in tasks based on objects of reality.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio
