A Cidade do Trabalho: usos do património industrial (S. João da Madeira)

S. João da Madeira é uma localidade que desde cedo construiu os seus discursos em torno da identidade local sob o epíteto de Cidade do Trabalho. Mais recentemente, desde a última década do século XX, a cidade começou a olhar para a sua dimensão industrial do ponto de vista do seu cunho patrimonial, dentro do quadro emergente das políticas culturais e de identidade, no qual as identidades particulares – como à escala local – se querem afirmar no plano global. Partindo de uma primeira análise dos processos contemporâneos de patrimonialização do industrial no contexto de S. João da Madeira, concretizados pela via dos museus e do turismo, num trabalho de projeto que se apresenta como fase de investigação preliminar de um futuro trabalho de doutoramento, questiona-se como a antropologia poderá pensar o conceito de cultura popular fora dos contextos normalmente a estes atribuídos e como, consequentemente, poderá problematizar as fronteiras daquilo que poderá ser considerado ou não Património Cultural Imaterial (PCI), categoria com a qual a disciplina está historicamente comprometida.

Analysis of the detection coefficient for the association between leprosy and pregnancy in the integration region of Carajas, State of Para, Brazil

Introduction The association between leprosy and pregnancy is currently poorly understood and has been linked to serious clinical consequences. Methods A retrospective study between 2007 and 2009 was performed in the integration region of Carajás, Brazil on a population of pregnant lepers, with non-lepers of ages 12-49 years serving as the reference population. Results Twenty-nine pregnant lepers were studied during the study period. The detection rates (DRs) for the studied association were 4.7 in 2007, 9.4 in 2008, and 4.3 in 2009. Conclusions The Carajás region presented a medium pattern of endemicity during most of the study period, with a high DR found in 2008.

Association between histological findings, aminotransferase levels and viral genotype in chronic hepatitis C infection

Introduction: The genomic heterogeneity of hepatitis C virus (HCV) influences liver disorders. This study aimed to determine the prevalence of HCV genotypes and to investigate the influence of these genotypes on disease progression. Methods: Blood samples and liver biopsies were collected from HCV-seropositive patients for serological analysis, biochemical marker measurements, HCV genotyping and histopathological evaluation. Results: Hepatitis C virus-ribonucleic acid (HCV-RNA) was detected in 107 patients (90.6% with genotype 1 and 9.4% with genotype 3). Patients infected with genotype 1 exhibited higher mean necroinflammatory activity and fibrosis. Conclusions: HCV genotype 1 was the most prevalent and was associated with greater liver dysfunction.

Association between the degree of physical impairment from leprosy and dependence in activities of daily living among the elderly in a health unit in the State of Minas Gerais

Introduction In addition to the common alterations and diseases inherent in the aging process, elderly persons with a history of leprosy are particularly vulnerable to dependence because of disease-related impairments. Objective determine whether physical impairment from leprosy is associated with dependence among the elderly. Methods An analytical cross-sectional study of elderly individuals with a history of leprosy and no signs of cognitive impairment was conducted using a database from a former leprosy colony-hospital. The patients were evaluated for dependence in the basic activities of daily living (BADL) and instrumental activities of daily living (IADL), respectively) and subjected to standard leprosy physical disability grading. Subsequently, descriptive and univariate analyses were conducted, the latter using Pearson's chi-squared test. Results A total of 186 elderly persons were included in the study. Of these individuals, 53.8% were women, 49.5% were older than 75 years of age, 93% had four or less years of formal education, 24.2% lived in an institution for the long-term care of the elderly (ILTC), and 18.3% had lower limb amputations. Among those evaluated, 79.8% had visible physical impairments from leprosy (grade 2), 83.3% were independent in BADL, and 10.2% were independent in IADL. There was a higher impairment grade among those patients who were IADL dependent (p=0.038). Conclusion s: The leprosy physical impairment grade is associated with dependence for IADL, creating the need for greater social support and systematic monitoring by a multidisciplinary team. The results highlight the importance of early diagnosis and treatment of leprosy to prevent physical impairment and dependence in later years.

Surgical site infections in women and their association with clinical conditions

Introduction Surgical site infections (SSIs) can affect body tissues, cavities, or organs manipulated in surgery and constitute 14% to 16% of all infections. This study aimed to determine the incidence of SSIs in women following their discharge from a gynecology outpatient clinic, to survey different types of SSIs among women, and to verify the association of SSIs with comorbidities and clinical conditions. Methods Data were collected via analytical observation with a cross-sectional design, and the study was conducted in 1,026 women who underwent gynecological surgery in a teaching hospital in the municipality of Teresina, in the northeast Brazilian State of Piauí, from June 2011 to March 2013. Results The incidence of SSIs after discharge was 5.8% among the women in the outpatient clinic. The most prevalent surgery among the patients was hysterectomy, while the most prevalent type of SSI was superficial incisional. Comorbidities in women with SSIs included cancer, diabetes mellitus, and hypertension. Conclusions Surveillance of SSIs during the post-discharge period is critical for infection prevention and control. It is worth reflecting on the planning of surgical procedures for patients who have risk factors for the development of SSIs.

Analysis of the prevalence of dyslipidemia in individuals with HIV and its association with antiretroviral therapy

IntroductionAntiretroviral therapy (ART) has been used to treat large numbers of patients living with human immunodeficiency virus (HIV) infection. Lipid disorders are often observed in these patients, and include elevations in total cholesterol (TC) and triglycerides (TG).MethodsA cross-sectional study was performed using 333 patient records from the Regional Hospital of São José Doutor Homero de Miranda Gomes (HRSJHMG). The study population consisted of patients with HIV who were under medical follow up, either on or off drug treatment. The data were entered into Excel and exported to SPSS 16.0 for analysis using chi-square testing. We used prevalence ratios as the measure of association.ResultsLipid abnormalities were observed in 78.9% of individuals who received ART. Of the 308 subjects on ART, 59.1%, 41.9%, and 33.1% had TG, TC and low-density lipoprotein (LDL) abnormalities, respectively. The prevalence of LDL changes was 2.57-fold higher in individuals who had been using ART for more than 12 months, compared to those using ART for 6 to 12 months.ConclusionsHIV patients showed a significant increase in the association between TC and TG levels and the use of ART. In particular, changes in TC, LDL and TG were greater in individuals who had received ART for over more than 12 months.

Association between allergic responses and Schistosoma mansoni infection in residents in a low-endemic setting in Brazil

Introduction Schistosomiasis is endemic in 76 countries and territories. Several studies have found an inverse correlation between parasitic disease and the development of allergies. The purpose of the present study was to determine whether infection with Schistosoma mansoni in subjects with a low parasite load is protective against allergy. The final sample consisted of 39 S. mansoni-positive and 52 S. mansoni-negative residents of a small community in northeastern Brazil. Methods All subjects were submitted to the Kato-Katz test, anti-S. mansoni IgG measurement, the prick test for aeroallergens, eosinophil counts and serum IgE measurement. Results Subjects who reacted to one or more antigens in the prick test were considered allergic. Only 7 S. mansoni-positive subjects (17.9%) reacted to one or more antigens, whereas 20 S. mansoni-negative subjects (38.5%) tested positive for allergy. Conclusions Our findings suggest that, in areas of low endemicity, infection with S. mansoni significantly reduces the risk of the development of allergy in subjects with a low parasite load.

Triatominae (Hemiptera, Reduviidae) in the Pantanal region: association with Trypanosoma cruzi, different habitats and vertebrate hosts

ABSTRACTINTRODUCTION: The transmission cycle of Trypanosoma cruzi in the Brazilian Pantanal region has been studied during the last decade. Although considerable knowledge is available regarding the mammalian hosts infected by T. cruzi in this wetland, no studies have investigated its vectors in this region. This study aimed to investigate the presence of sylvatic triatomine species in different habitats of the Brazilian Pantanal region and to correlate their presence with the occurrences of vertebrate hosts and T. cruzi infection.METHODS: The fieldwork involved passive search by using light traps and Noireau traps and active search by visual inspection. The light traps were placed at five selected points along forested areas for seven nights during each of the nine excursions. At each point where a light trap was set, eight Noireau traps were placed in palm trees and bromeliads.RESULTS: In all, 88 triatomine bugs were collected: two and one individuals from light traps and Noireau traps, respectively; three from peridomestic areas; 23 in coati nests; and 59 in thornbird nests. In this study, active search in microhabitats showed higher efficiency than passive search, since 95% of the triatomine bugs were caught in nests. Further, triatomine bugs were only found to be infected by T. cruzi in coati nests.CONCLUSIONS: Coati nests might act as a point of convergence and dispersion for triatomine bugs and mammal hosts infected by T. cruzi, thereby playing an important role in the sylvatic cycle of T. cruziin the Pantanal region.

Prevalence of hypovitaminosis D and its association with oral lesions in HIV-infected Brazilian adults

Abstract: INTRODUCTION: This study assessed the prevalence of hypovitaminosis D and its association with oral candidiasis and clinical parameters of periodontitis (CPP) in HIV-infected patients. METHODS: Periodontal examinations for the 113 HIV-infected patients were recorded using the Community Periodontal Index. A cytological smear from the lateral borders of the tongue was performed to evaluate candidiasis. RESULTS: The frequency of hypovitaminosis D was 23.9%. In multivariate analysis, only the duration of exposure to HIV was associated with CPP [OR 4.72 (95% CI: 0.97-23.00)]. CONCLUSIONS: The prevalence of hypovitaminosis D was 23.9% and was not related with oral candidiasis or CPP.

Primary biliary cirrhosis and myopathy: an uncommon association

Primary biliary cirrhosis (PBC) is a cholestatic liver disease, which is characterized by a chronic inflammatory destruction of intrahepatic bile ducts. It is a rare disorder whose precise etiology is still to be elucidated. Even though the liver is the principal target of PBC, other organ systems also might be affected. Muscular involvement has rarely been described in this disease, and in the majority of cases, muscular weakness has been interpreted as polymyositis. We report the case of a 48-year-old woman suffering from classic PBC, in association with a myopathy whose histological features are distinct from the cases reported before. We also performed a MEDLINE research for PBC and concomitant muscular diseases.

Modelo hidrogeológico e rede de monitorização da água subterrânea na Zona Industrial e Logística de Sines (ZILS)

Na Zona Industrial e Logística de Sines (ZILS) estão instaladas empresas e indústrias que interferem na quantidade e qualidade da água subterrânea de aquíferos da região. Estas utilizam e libertam poluentes que, consequentemente, quando não cumpridas as normas de segurança, podem causar impactes no ambiente. A ZILS situa-se no Sistema Aquífero de Sines, na Massa de Água 032-Sines, este é constituído por dois aquíferos, um superficial detrítico livre e outro carbonatado profundo confinado. Apesar de se encontrarem separados em grande parte da sua extensão, na região sul, estes aquíferos encontram-se em conexão hidráulica. Esta ocorre a este da falha da Maria das Moitas onde, a partir da qual e até ao limite com o Paleozóico, não foi reconhecida a unidade argilosa do Miocénico, aumentado assim a vulnerabilidade do sistema e a pertinente otimização da rede de monitorização. Para a realização de um estudo mais aprofundado e avaliação dos efeitos sobre as águas subterrâneas na área de estudo, definiu-se uma metodologia de trabalho que engloba 4 etapas: (i) revisão bibliográfica; (ii) recolha de dados geológicos e hidrogeológicos dos arquivos da aicep Global Parques, S.A., SNIRH e LNEG; (iii) tratamento e análise dos dados obtidos em ArcGIS e traçado de perfis geológicos interpretativos; (iv) realização do modelo geológico e hidrogeológico e respetiva adequação da rede de monitorização. O modelo hidrogeológico concebido mostra que o escoamento no Sistema Aquífero de Sines se processa, predominantemente, de E para W a partir do limite situado no contacto por falha entre as unidades do Paleozóico e Meso-Cenozóico com orientação, quase perpendicular, à ribeira dos Moinhos. A este deste alinhamento é assinalada a presença de um aquífero fissurado sob as areias do Plio-Plistocénico localizado na Formação de Mira. O escoamento neste aquífero faz-se de NE para SW, em direção ao oceano, para a praia de S. Torpes.

Estudo e sugestões de melhorias de eficiência energética numa empresa do sector industrial de carnes

Desta dissertação resultou uma análise ao consumo energético associado aos produtos mais comerci-alizados por uma Empresa, inserida no sector industrial de carnes, e de respectivas medidas de ges-tão de energia eléctrica e de implementação de tecnologia térmica para optimizara a eficiência ener-gética da instalação. A avaliação realizada nesta dissertação permitiu identificar os processos que mais energia consomem, nomeadamente todos os produtos que envolvem a fumagem. Com base nes-tes resultados a empresa pode identificar as prioridades em termos de redução e melhoria da eficiên-cia energética. O estudo de gestão da energia eléctrica permitiu concluir que é mais proveitoso man-ter em funcionamento os processos pontuais durante os períodos nocturnos ou durante o fim-de-semana, permitindo, no segundo caso, obter uma poupança de 16% nos custos associados de cada vez que se colocar a linha de produção de peito de peru fumado entre o período semanal para o perí-odo entre sexta-feira e domingo, visto ser a linha de produção estudada que mais energia eléctrica consome. Na análise de pré-aquecimento dos fluidos utilizados na empresa através de recuperadores de calor, concluiu-se que é mais benéfico pré-aquecer a água utilizada para o processo de fumagem, visto obter-se uma poupança económica de 6 € e 11,8 m3 de gás natural por aplicação, ou seja, de cada vez que é utilizada água pré-aquecida através deste procedimento, tendo-se obtido valores de poupança energética entre 24 e 60% para os vários fluidos estudados.

Ferramenta de simulação para robô industrial

Actualmente, os meios de produção industrial estão em constante desenvolvimento, de forma a corresponderem a um mercado cada vez mais globalizado, caracterizado por uma forte competição, uma pressão na redução de custos, e a existência de produtos e serviços personalizados. Entretanto, ao nível de equipamento de robótica, também se tem notado esta pressão por parte do mercado, exigindo-se equipamento com uma complexidade crescente, tanto ao nível da sua morfologia, do seu controlo e da sua utilização. Ao nível da sua utilização, tornou-se então necessário adoptar abordagens que permitam um maior controlo quanto a falhas de manuseamento e respectiva modelação destes robôs. Uma destas abordagens é a simulação. A simulação é uma das áreas com maior crescimento a nível tecnológico, sendo utilizada em várias áreas de tecnologia e informação devido à sua capacidade de adaptação, tornando-se numa área bastante dinâmica e flexível. Dentro dum contexto de robôs industriais, as aplicações mais típicas consistem na programação “offline” de robôs e na aprendizagem de robótica, tendo como objectivo estudar e analisar os comportamentos de determinados sistemas, com o intuito de reduzir a necessidade de intervenção humana em tarefas repetitivas, perigosas e dispendiosas. Além disso, a simulação está também presente na computação informática nas salas de aulas, por forma a auxiliar o professor. Foi então idealizado um sistema de simulação capaz de imitar um robô industrial em que os alunos terão que conseguir controlar, para que os vários testes sejam primeiramente implementados no simulador, diminuindo assim, o risco de causar acidentes no seu congênere real durante a fase de testes. O sistema consiste numa interface em que possibilita ao utilizador fazer um controlo manual do robô simulado, assim como ser capaz de o controlar por comandos requisitados por uma aplicação exterior através de serviços WEB, permitindo assim, a simulação de vários testes no robô industrial em causa.

A systematic methodology to analyse the performance and design configurations of business interoperability in cooperative industrial networks

This thesis proposes a methodology for modelling business interoperability in a context of cooperative industrial networks. The purpose is to develop a methodology that enables the design of cooperative industrial network platforms that are able to deliver business interoperability and the analysis of its impact on the performance of these platforms. To achieve the proposed objective, two modelling tools have been employed: the Axiomatic Design Theory for the design of interoperable platforms; and Agent-Based Simulation for the analysis of the impact of business interoperability. The sequence of the application of the two modelling tools depends on the scenario under analysis, i.e. whether the cooperative industrial network platform exists or not. If the cooperative industrial network platform does not exist, the methodology suggests first the application of the Axiomatic Design Theory to design different configurations of interoperable cooperative industrial network platforms, and then the use of Agent-Based Simulation to analyse or predict the business interoperability and operational performance of the designed configurations. Otherwise, one should start by analysing the performance of the existing platform and based on the achieved results, decide whether it is necessary to redesign it or not. If the redesign is needed, simulation is once again used to predict the performance of the redesigned platform. To explain how those two modelling tools can be applied in practice, a theoretical modelling framework, a theoretical Axiomatic Design model and a theoretical Agent-Based Simulation model are proposed. To demonstrate the applicability of the proposed methodology and/or to validate the proposed theoretical models, a case study regarding a Portuguese Reverse Logistics cooperative network (Valorpneu network) and a case study regarding a Portuguese construction project (Dam Baixo Sabor network) are presented. The findings of the application of the proposed methodology to these two case studies suggest that indeed the Axiomatic Design Theory can effectively contribute in the design of interoperable cooperative industrial network platforms and that Agent-Based Simulation provides an effective set of tools for analysing the impact of business interoperability on the performance of those platforms. However, these conclusions cannot be generalised as only two case studies have been carried out. In terms of relevance to theory, this is the first time that the network effect is addressed in the analysis of the impact of business interoperability on the performance of networked companies and also the first time that a holistic approach is proposed to design interoperable cooperative industrial network platforms. Regarding the practical implications, the proposed methodology is intended to provide industrial managers a management tool that can guide them easily, and in practical and systematic way, in the design of configurations of interoperable cooperative industrial network platforms and/or in the analysis of the impact of business interoperability on the performance of their companies and the networks where their companies operate.
