Security of smart home-smartphones systems
No full textWith technology increasingly present in people’s lives, smart homes are gaining more and more impact each day. While in the past smart homes consisted in presence sensors, cameras and automatic shutters, nowadays they are composed of several sensors and equipment that can control and monitor different things, such as temperature or heat. The homeowners want to control and monitor their home through applications on their smartphone which contributed to the smart homes-smartphones system concept. These are systems that control people’s privacy, so various security mechanisms must be implemented to mitigate vulnerabilities. In this paper we present main vulnerabilities of these systems and main proposals to mitigate threats.5311-8814-F0ED | Sara Maria da Cruz Maia de Oliveira PaivaN/
Construção e validação de uma escala de adaptação a ostomia de eliminação

a review
Get PDFWomen have a number of specificities that differentiate them from men. In particular, the role of sex steroid hormones and the menstrual cycle (MC) significantly impact women’s physiology.
The literature has shown nonlinear relationships between MC, exercise, and nutritional intake.
Notably, these relationships are bidirectional and less straightforward than one would suppose. For example, the theoretical implications of the MC’s phases on exercise performance do not always translate into relevant practical effects. There is often a disconnect between internal measures (e.g., levels of hormone concentrations) and external performance. Furthermore, it is not entirely clear how nutritional intake varies across the MC’s phases and whether these variations impact on exercise performance. Therefore, a thorough review of the existing knowledge could help in framing these complex relationships and potentially contribute to the optimization of exercise prescription and nutritional intake according to the naturally occurring phases of the MC. Throughout this review, an emerging trend is the lack of generalizability and the need to individualize interventions, since the consequences of the MC’s phases and their relationships with exercise and nutritional intake seem to vary greatly from person to person. In this sense, average data are probably not relevant and
could potentially be misleading.D915-7373-ED16 | Cesar LeaoN/
Ferramentas de avaliação para avaliar a independência: uma scoping review
Get PDFIntrodução: A independência é uma área privilegiada de intervenção do enfermeiro. A maioria das situações que motivam os internamentos, levam a uma considerável diminuição da independência da pessoa. Existem muitas escalas que mensuram a independência, pelo que é importante conhecê-las e aplicá-las adequadamente.
Metodologia: Scoping review com base nos princípios preconizados pelo Joanna Briggs Institute. Realizou-se uma pesquisa nas bases de dados: Scopus (excluindo MEDLINE), CINAHL complete (via EBSCO, Excluindo MEDLINE) e MEDLINE (via PubMed).
Resultados: Após a análise segundo os critérios de inclusão estabelecidos, foram selecionados 26 artigos, os quais fazem alusão a seis instrumentos diferentes que avaliam a independência, a saber: Functional Independence Measurement, Instrumental Activity of Daily Living Scale, Barthel Index, Katz Index of Independence in Activities of Daily Living, a Assessment of Living Skills and Resources e a Utrecht Scale for Evaluation of Rehabilitation.
Discussão: Os títulos dos instrumentos por vezes não traduzem se mensuram apenas e/ou só a independência. Quando combinada a aplicação dos diferentes instrumentos, poderá no seu conjunto dar resposta ao conceito de independência.
Conclusão: Na prática clínica é importante conhecer todos os instrumentos ao dispor para a sua aplicação,
conhecendo também as suas caraterísticas e aplicabilidade. Reconhece-se que os resultados da aplicação destas ferramentas, permite caraterizar as necessidades das pessoas e responder de uma forma atempada a essas necessidades.DA10-CEBF-4D75 | Maria Salomé Martins FerreiraN/
The nature and dimensions of achievement goals: mastery, evaluation, competition, and self-presentation goals
Get PDFThe present study aimed to clarify the nature and dimensions of achievement goals and to examine structural differences in students' goals across school levels. Participants were 134 students from 5th and 6th grades, and 423 students from 7th to 9th grades. A variety of achievement goals were assessed, including mastery goals and several performance-related goals representing three main dimensions: competition, self-presentation, and valence. Two alternative models were tested, using confirmatory factor analysis. For middle-school students a three factor model with presentation, competition, and simple evaluation/mastery goals, was found χ²(132, N = 134) = 160.9, p < .001; CFI = .94; RMSEA = .04, 95%CI [.02 - .06]. In the junior-high sample, one avoidance factor, one competition factor, and a simple evaluation/mastery factor, best fitted the data χ²(114, N = 423) = 269.8638 p < .001; CFI = .93; RMSEA = .06, 95%CI [.05 - .07] thus suggesting that distinct dimensions organize younger and older students' motivation. However, common to both grade levels was the existence of (a) separate but low incidence competition goals, and (b) simple evaluation goals, which encompass neither self-presentation nor competition, and are closely linked to mastery goals. Moreover, significant differences were found in the relative importance attached by students to the different types of goals (p < .001 for all comparisons), both at middle-school F(2, 266) = 220.98; p < .001; η2 = .624) and at junior-high school F(2, 820) = 464.4; p < .001; η2 = .531.8C1E-AFB9-6BE1 | Maria Teresa Martins GonçalvesN/
Contactless smart screening in nursing homes : an IoT-enabled solution for the COVID-19 era
Get PDFIn the COVID-19 era, the provision of health indicators seamlessly and without contact, in groups at risk such as the elderly, is crucial due to the fast spread of the disease and the need to act quickly to contain its evolution. Continuous monitoring of vital signs, such as body temperature and cardio-respiratory
rates, can be vital in early detection and prediction of COVID-19, which rapidly progresses and particularly affects the elderly population in nursing homes. Conventional clinical methods used for monitoring vital signs are contact-based, require contact sensors that need to be precisely attached by a trained health professional, are less convenient for repeatable measurements, and not practical for long-term monitoring. On the other hand, contactless vital signs monitoring using radar-based techniques,
or IR-thermal imaging, do not require the attachment of physical electrodes and can be of great value in health screening of patients and help health professionals in early detection of the COVID-19 in the elderly population, in the specific context of nursing houses. This work describes the design and specification of a low-cost contactless health screening system for nursing homes, and includes the design of an IoT Edge device that can be placed above the beds where patients rest, allowing the
continuous acquisition of health information and its processing without any type of contact and invasiveness.911A-2C18-106F | Carlos Jorge Enes Capitão de AbreuN/
differences in motor competence and cardiorespiratory fitness
Get PDFThe purpose was to identify classes of different developmental trajectories of BMI and testing them for
differences in motor competence (MC) and cardiorespiratory fitness (CRF), in children and adolescents (4
to 13 years of age). This was a 5 years’ longitudinal study with six cohorts. One hundred and forty-seven
children (69 girls) divided into six cohorts participated. At baseline, the youngest and the oldest cohorts
had 4 and 11 years of age, respectively. Height and weight were assessed, and BMI was calculated. MC
was assessed with KTK and TGMD-2, and CRF was assessed with one-mile run/walk. Developmental
trajectories of BMI were identified using latent class linear-mixed modelling. Latent class membership
was explained according to covariates of MC and CRF. Two meaningful classes were identified. Class 1
(78.92% of the participants) showed lower initial BMI and a lower slope compared to class 2 (21.08% of
the participants) (all ps < 0.001). Class membership only predicted trajectories in motor coordination, with
children in class 1 having a better development.
In conclusion, this study identified two meaningful trajectories for children based on their BMI
development across five time points. In line with previous research, children with slower increasing
BMI showed better motor coordination improvements.4811-99FE-2ECD | Luis Paulo RodriguesN/
Impacts of therapeutic horticulture on happiness and loneliness in institutionalized clients with mental health conditions
Get PDFIntroduction: Therapeutic horticulture (TH) can be considered a non-pharmacological approach to support psychiatric treatments for
the improvement of physical and mental health, but information is lacking on whether it has advantages as compared to more
conventional occupational therapies (OTs).
Method: The study focused on institutionalized 25 clients attending TH among other OTs and 15 clients attending OT other than TH. The
measures used were the ‘Subjective Happiness Scale’ (SHS) and the ‘Social and Emotional Loneliness Scale for Adults’ (SELSA-S),
along with sociodemographic and clinical data. The study design was descriptive, observational and cross-sectional.
Results: Scores obtained from the SHS and SELSA-S were generally similar for both groups, although 40% of clients in the TH group
perceived relaxation. These are in agreement with previous studies performed with chronic schizophrenia clients reporting that TH
might effectively decrease depression/anxiety symptoms, but the feeling of hopelessness and quality of life did not change, probably
due to long-term institutionalization and required medication that may limit other effects. Within the TH group, clients preferred
specific horticultural tasks and more days/week attending activities decreased loneliness and increased happiness.
Conclusion: TH interventions as an integrative treatment option merits further study on both process and outcome evaluation, to
maximize its effectiveness.6B1D-516F-1A2A | Luís Miguel Cortez Mesquita de BritoN/
Clinical application of bioextracts in supporting the reproductive system of animals and humans: potential and Limitations
Get PDFThere is an increasing demand of spices and herbs in developing countries due to the beneficial effects of plants and herbal
preparations as medicines. The basic technological process of obtaining extracts from natural raw materials is extraction,
consisting in etching with solvents. Plant extracts are extremely complex, multicomponent mixtures obtained from flowers, fruits,
leaves, stems, twigs, or seeds of various plant materials. They are a rich source of polyphenols, flavonoids, phytosterols, carotenoids, and vitamins. The search for alternative methods of treatment is increasingly replacing the scientists’ excessive focus on
the healing properties of bioextracts. Recent research offers great hope for the development of alternative methods to improve the
reproductive system. The use of animal models in experimental research has increased knowledge regarding the beneficial effects
of bioextracts on both male and female reproductive systems and reproductive cells. Demonstrating the positive effect of plant
extracts creates new opportunities for the use of biowaste, which is a by-product in various production sectors. The aim of this
review is to present the functional properties of extracts of natural origin, a cross section of modern methods of their preparation,
and a discussion of the possibilities of their use in the auxiliary reproductive system.FE1B-06B2-126F | José Pedro Pinto de AraújoN/
Conductivity of La0.95Sr0.05Ga0.90 Mg0.10O3-δ obtained by mechanical activation
Get PDFDense ceramics of La0.95Sr0.05Ga0.90Mg0.10O3−δ (LSGM) were obtained from La2O3, SrO, Ga2O3 and MgO precursors activated by dry grinding in a high-energy planetary ball-mill. Samples sintered at 1450 ◦C for 4 h have an average grain size of ca. 250 nm. This value increases to 5 μm when the sample is annealed for 40 h at the same temperature. Samples prepared by a conventional ceramic route were also obtained with a grain size of 13.5 and 20.5 μm , after sintering at 1550 ◦C for 4 and 40 h, respectively. Impedance spectroscopy data revealed similar grain conductivities for both materials. However, a significant degradation was observed on ageing the LSGM prepared by the conventional ceramic route, probably due to compositional alterations at the grain boundaries. This degradation was not present in the material prepared from mechanically activated precursors. Grain size effects on the electrical conductivity were analysed to determine the effective grain boundary conductivity and the brick-layer model is assumed to estimate the grain boundary thickness.371C-9F16-EBDE | Eduarda GomesN/
