Indoor air quality in Portuguese schools: levels and sources of pollutants

Indoor air quality (IAQ) parameters in 73 primary classrooms in Porto were examined for the purpose of assessing levels of volatile organic compounds (VOCs), aldehydes, particulate matter, ventilation rates and bioaerosols within and between schools, and potential sources. Levels of VOCs, aldehydes, PM2.5 , PM10 , bacteria and fungi, carbon dioxide (CO2 ), carbon monoxide, temperature and relative humidity were measured indoors and outdoors and a walkthrough survey was performed concurrently. Ventilation rates were derived from CO2 and occupancy data. Concentrations of CO2 exceeding 1000 ppm were often encountered, indicating poor ventilation. Most VOCs had low concentrations (median of individual species <5 μg/m(3) ) and were below the respective WHO guidelines. Concentrations of particulate matter and culturable bacteria were frequently higher than guidelines/reference values. The variability of VOCs, aldehydes, bioaerosol concentrations, and CO2 levels between schools exceeded the variability within schools. These findings indicate that IAQ problems may persist in classrooms where pollutant sources exist and classrooms are poorly ventilated; source control strategies (related to building location, occupant behavior, maintenance/cleaning activities) are deemed to be the most reliable for the prevention of adverse health consequences in children in schools.

Exploration of portuguese-bengal cultural heritage throught museological studies

The Portuguese came to Bengal in the early 16th century for trading. Between 1575 and 1600, they established many colonies on the banks of river Ganga, like Chinsura, Hooghly (Porto Pequeno), Satagaon, Gopalpur and Bandel, covering the eastern part of India. During their stay, Portuguese built many churches, schools and charitable institutions. Churches of Augustinians and Jesuits became popular tourist destinations until today. Although by the 18th century, the Portuguese presence had almost disappeared from Bengal with the emergence of British imperialism, the 500 years old (approx.) Portuguese culture is still living in modern Bengal, in the form of tangible and intangible heritage. Traces of the Portuguese impact could be seen in Bengali language, literature, folk-tales, folksongs, cuisines, agriculture, religion, cinema and trade. Some of these are included in the academic curriculum of history at school, college and university levels. In this context, research has been undertaken in the past and is still ongoing in several universities. However, heritage studies under a museological point of view have not yet been initiated at the university level. Though Goa, Panaji, Calicut, Chennai and Nagapattanam were the Portuguese centers for long periods and research has been conducted there along with the establishment of some museums,

Portuguese health care costs related to asbestos exposure: a cost-of-illness study on mesothelioma hospital admission in the period 2000-2015

Background: Portugal has a temperate climate and low industrialization levels existing in the period after World War II, when asbestos materials were used worldwide, has contributed to the generalized belief of low usage of those materials. - Such supposition lacks confirmation; - There is no specific registry of asbestos-related diseases, workers asbestos exposure or asbestos industrial use; - Mesotheliomas are rare neoplasms strongly related to asbestos exposure so they can be used to understand the possible dimension of past exposure to asbestos; - It was estimated that professional diseases under notification was up to 90% for asbestos-related diseases, mainly mesotheliomas.

Constructing and (re) constructing professional identities: an analysis on portuguese social educators

Institutions need to be aware of the complex way in which professional trajectories are built upon in order to offer under graduate and graduate students’ different possibilities for developing needed competences to display in practice. This paper focuses on the study2 conducted by ESEPF on its former students of Social Education, through a written questionnaire analysing different parameters of their professional transitions, from entrance at training, first job and entrance on the labour market, present work situations, developed competences and perceptions of the Social Educator role on Portuguese Society, among others. Results will be presented and discussed. Particular focus will be given on the specific role of Social Education and its distinctive features towards other “social work” professions.

Measuring attachment to life in old age: the Portuguese version of the Positive Valuation of Life Scale (Positive VOL)

Purpose This study aims to present the psychometric properties of the Portuguese version of the Positive Valuation of Life Scale (Lawton et al. in J Aging Ment Healt 13:3–31, 2001). Method Sample included 207 community-dwelling elders (129 women; MAge = 77.2 years, SD = 7.5). The data collection included the translated and adapted Portuguese version of Positive Valuation of Life Scale, Life Satisfac- tion Index Z, Meaning in Life Questionnaire and Geriatric Depression Scale. Results From exploratory factor analysis, two factors emerged, existential beliefs and perceived control, ex- plaining 49 % of the total variance. Both factors were positively related with meaning in life and life satisfaction and negatively related with depression (p\0.05). The values obtained for internal consistency for the total scale and for each subscale were good (a [ 0.75). Conclusion The Portuguese version of Positive VOL Scale represents a reliable and valid measure to capture the subjective experience of attachment to one’s life. The two-factor structure is an update to Lawton’s previous work and in line with findings obtained in the USA (Dennis et al. in What is valuation of life for frail community-dwelling older adults: factor structure and criterion validity of the VOL, Thomas Jefferson University, Center for Applied Research on Aging and Health Research, 2005) and Japan (Nakagawa et al. in Shinrigaku Kenkyu 84:37–46, 2013). Future research is required to investigate VOL predictors and the potential changes toward the end of the life span.

Factors Affecting the Body Mass Index in Adolescents in Portuguese Schools

The prevalence of overweight and obesity among children is increasing; hence, it was aimed to assess the Body Mass Index (BMI) in school children aged from 10 to 18 years for girls and to 17 for boys, as well as to identify the factors influencing BMI. This study included 742 students who answered a questionnaire previously approved for application in schools. The results showed some sociodemographic factors associated with BMI classes: age, school year, practicing high competition sport, being federate in a sport or having a vegetarian diet. The educational factors associated with BMI classes included only seminars given at school by a nutritionist. Behavioural factors significantly associated with BMI included: learning in classes, playing in the open air, reading books or use of internet. As conclusion, the results demonstrated that several factors affect BMI, and hence some actions could be taken in order to change them so as to reduce the prevalence of overweight, namely reinforcing the role of school and a more active participation of nutritionists in the education of the adolescents.

Perception of health benefits of dietary fibre among the Portuguese population

Introduction: Dietary iber (DF) has been part of human diet since ever, and its beneits for the human health have been well estab-lished and scientiically conirmed. Among these stand improved gastrointestinal functions, prevent cholesterol, diabetes or CVD. Objectives: To study the level of knowledge of people residing in Portugal about the health effects related to an adequate ingestion of DF. Methods: This is a descriptive cross-sectional study carried out on a non-probabilistic sample of 382 adults residing in Portugal. The questionnaire included a section about the socio-demographic characteristics (age, gender, level of education and living environ- ment) and another about the relation between dietary iber and possible beneicial effects to treat and prevent diseases. The data was treated using the SPSS software (V22). Results: The results allowed concluding that people were dif- ferently informed about the effects of DF in preventing and/or treating different diseases, being constipation the most recog- nized, followed in decreasing order by obesity, bowel cancer, cholesterol, cardiovascular diseases, diabetes and breast can- cer. The results also showed that signiicant differences were encountered between age groups for most of the diseases evalu- ated, but not between genders, levels of education or living en- vironments. Conclusions: Generally, it was concluded that the participants in this study were relatively well informed about the roles of DF in preventing and/or treating various diseases.

Low birth weight and cardiovascular risk in a Portuguese sample

The aim was to evaluate whether it had a similar effect in a Portuguese sample and if low weight classes – low weight (LW <2500g), very low weight (VLW <1500g) and extremely low weight (ELW <1000g) – had statistically significant differences between them.

Government management of tourism in fostering residents support for sustainable tourism development: Evidence from a Portuguese historic town

This study proposes a conceptual framework that explores the correlations between economic dependence (ED), local government management of tourism (GMT), perceived tourism benefits and costs, and support for sustainable tourism development (STD). A quantitative research design was adopted. Data collection was carried out by personal survey applied to 300 residents of the small historic town of Lamego, located within the Douro Valley World Heritage Site. Structural equation modelling methods were employed to analyse the proposed model. Results suggest that GMT has a significant effect on the perceived impacts of tourism, both in the positive and in the negative. The effect of GMT in fostering residents’ support to STD was also empirically supported. Additionally, it was also determined that positive perceptions of the impacts of tourism directly influence support to STD. Nevertheless, ED does not have a significant effect either on perceivedbenefits, nor on perceived costs or on residents’ support to STD. Likewise, perceptions of the negative impacts do not predict residents’ support to STD.

Intercultural prejudices and misconceptions in portuguese school books

In this paper we want to analyze the intercultural values included in some Portuguese school books. We will show/analyze some prejudices and misconceptions as well as good examples of excellent intercultural education practices in these manuals.

The other of myself: representations of portuguese teachers about intercultural education related concepts

Having into consideration that we live in a multicultural society, it is important to analyse how far people view and accept each other. Therefore, one should reflect upon concepts such as: representations and stereotypes, because they are interpersonal constructs which are (re)built during the interaction of different sociocultural groups. In this study, we focus our attention on the representations a sociocultural group – Portuguese teachers - has of intercultural education and the role of teachers and educators in the promotion of an intercultural approach at school. We believe that teachers have the responsibility to: find out the representations students have of the Other; reconfigure stereotyped representations; and create representations which favor dialogue and relationship with the Other flourish. Following a sociolinguistic approach (Müller, 1998; Vasseur, 2001; Vasseur & Hudelot, 1998), which is related to the construction and diffusion of representations in discourse, we analyse the discourse of teachers during a workshop called ‘The Other and Myself’, in which they build and discuss about a didactic mask that portrays their own vision of both themselves and their ideas of intercultural education.

Next-generation sequencing of hereditary hemochromatosis-related genes: novel likely pathogenic variants found in the Portuguese population

Hereditary hemochromatosis (HH) is an autosomal recessive disorder characterized by excessive iron absorption resulting in pathologically increased body iron stores. It is typically associated with common HFE gene mutation (p.Cys282Tyr and p.His63Asp). However, in Southern European populations up to one third of HH patients do not carry the risk genotypes. This study aimed to explore the use of next-generation sequencing (NGS) technology to analyse a panel of iron metabolism-related genes (HFE, TFR2, HJV, HAMP, SLC40A1, and FTL) in 87 non-classic HH Portuguese patients. A total of 1241 genetic alterations were detected corresponding to 53 different variants, 13 of which were not described in the available public databases. Among them, five were predicted to be potentially pathogenic: three novel mutations in TFR2 [two missense (p.Leu750Pro and p.Ala777Val) and one intronic splicing mutation (c.967-1GNC)], one missense mutation in HFE (p.Tyr230Cys), and one mutation in the 5′-UTR of HAMP gene(c.-25GNA). The results reported here illustrate the usefulness of NGS for targeted iron metabolism-related gene panels, as a likely cost-effective approach for molecular genetics diagnosis of non-classic HH patients. Simultaneously, it has contributed to the knowledge of the pathophysiology of those rare iron metabolism-related disorders.

"Knock, knock! Is it english or portuguese sign language?"

A presente investigação mostra a importância do contacto de crianças muito jovens com línguas estrangeiras. Este trabalho concentra-se na tentativa de investigar, numa abordagem plurilingue, com enfoque para a Língua Inglesa e a Língua Gestual Portuguesa, a sensibilização de um grupo de alunos do 1º Ciclo do Ensino Básico para uma língua diferente da sua língua materna. Nesta pesquisa, adotou-se uma postura de investigação-ação, apoiando-se com grande particularidade numa metodologia qualitativa e com menor relevância numa metodologia quantitativa, onde os alunos, através das várias atividades que desenvolveram foram adquirindo diferentes competências nas duas línguas. Isto permitiu aos alunos despertarem todas as suas potencialidades para a aprendizagem destas duas línguas (Língua Inglesa e Língua Gestual Portuguesa), tendo como ponto de partida a sua sensibilização e a aprendizagem de alguns vocábulos. Acreditamos que esta abordagem plurilíngue poderá auxiliar os alunos no desenvolvimento de habilidades linguísticas, cognitivas e pessoais tais como: a intercompreensão, o conhecimento de características específicas de diferentes línguas existentes em seu redor, a comparação linguística entre elas, a sua compreensão lexical, e por fim a competência em relacionar as línguas a culturas, e acima de tudo, o respeito e valorização da diversidade linguística e cultural. Foram utilizadas nas aulas atividades de nível de compreensão e produção oral, num processo de sensibilização e aprendizagem de alguns vocábulos destas línguas, sendo que os resultados foram posteriormente analisados, através de grelhas de observação das atividades, de dois inquéritos por questionário e fotos. Das observações e conclusões retiradas desta análise, confirmou-se que a sensibilização quanto à Língua Inglesa assim como quanto à Língua Gestual Portuguesa promove o desenvolvimento da criança, assim como a valorização da respetiva diversidade linguística e cultural.
