Intercultural awareness through. Digital storytelling

In today’s globalized world, communication students need to be capable of efficiently communicating across the globe. At ISCAP, part of the 3rd year syllabus in Translation and New Technologies course is focused on culture and the need to be culturally knowledgeable. We argue the approach to incorporate cultural aspects in HE needs to be studentcentered, in order to encompass not only intercultural awareness, but also the 21st century skills students need to be successful and competent citizens. Additionally, as studies have shown, the manipulation of digital tools fosters greater student involvement in learning activities. We have adopted Digital Storytelling - multimodal storytelling technique - to promote a personal, student-centered reflection on intercultural communication. We intend to present student and teacher perspectives on this learning experience and assess its relevance in HE contexts, based on the content analysis of student expressed perspectives on this activity as well as a multimodal analysis of the digital stories created. A preliminary analysis of our case study has demonstrated that Digital Storytelling potentiates two complimentary types of reflection: on the one hand, students felt the need to reflect on their own intercultural knowledge, create and adapt their finding in the form of a story; on the other hand, viewing others’ stories they have raised questions and demonstrated points of view otherwise ignored.

Fire safety barrier availability analysis

This paper shows several ways to analyse the performance of a safety barrier, depending on the objective to be achieved and present a method to analyse binary components usually present on sensor systems of safety barriers. An application example of a water-based fire system is presented and the Probability of Failure on Demand (PFD) of the sensor system is determined based on the analysis of pressure switches installed in this safety barrier. The knowledge of such information will allow the determination of safety barrier’s availability.

Georeferencing Road Accidents with Google Earth: Transforming Information into Knowledge for Decision Support

Over the last fifty years mobility practices have changed dramatically, improving the way travel takes place, the time it takes but also on matters like road safety and prevention. High mortality caused by high accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative statistical exercises which go no further than defining accident types. In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal publication of figures, either through simplistic tables or web pages. With considerable technological advances on geographical information technologies, research and development stayed rather static with only a few good examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The Google Earth platform was used to georeference the information in order to inform the public and the authorities of the accident locations, the nature of the location, and the causes and consequences of the accidents. This paper also gives future insights about augmented reality technologies, considered crucial to advances to road safety and prevention studies. At the end, this exercise could be considered a success because of numerous consequences, as for stakeholders who decide what to do but also for the public awareness to the problem of road mortality.

Multi-Agent Based Smart Grid Management and Simulation: Situation Awareness and Learning in a Test Bed with Simulated and Real Installations and Players

The rising usage of distributed energy resources has been creating several problems in power systems operation. Virtual Power Players arise as a solution for the management of such resources. Additionally, approaching the main network as a series of subsystems gives birth to the concepts of smart grid and micro grid. Simulation, particularly based on multi-agent technology is suitable to model all these new and evolving concepts. MASGriP (Multi-Agent Smart Grid simulation Platform) is a system that was developed to allow deep studies of the mentioned concepts. This paper focuses on a laboratorial test bed which represents a house managed by a MASGriP player. This player is able to control a real installation, responding to requests sent by the system operators and reacting to observed events depending on the context.

Contextual and Environmental Awareness Laboratory for Energy Consumption Management

The recent changes on power systems paradigm requires the active participation of small and medium players in energy management. With an electricity price fluctuation these players must manage the consumption. Lowering costs and ensuring adequate user comfort levels. Demand response can improve the power system management and bring benefits for the small and medium players. The work presented in this paper, which is developed aiming the smart grid context, can also be used in the current power system paradigm. The proposed system is the combination of several fields of research, namely multi-agent systems and artificial neural networks. This system is physically implemented in our laboratories and it is used daily by researchers. The physical implementation gives the system an improvement in the proof of concept, distancing itself from the conventional systems. This paper presents a case study illustrating the simulation of real-time pricing in a laboratory.

Inspeção, Diagnóstico e Reparação de Estruturas de Betão Armado

O mercado da reabilitação de estruturas em Portugal está em voga, sendo um nicho de mercado com evolução galopante nos últimos anos fruto da consciencialização das entidades responsáveis, assim como das necessidades de intervir no parque edificado cada vez mais degradado, resultando num estímulo para o mercado da construção face ao seu estado atual. As causas associadas à degradação prematura dos materiais estruturais resultam de erros de conceção e execução, assim como do facto de muitas estruturas de betão armado do parque habitacional edificado nas décadas de 60 e 70, estarem a atingir o fim do seu período de vida útil. Na avaliação do estado de degradação de estruturas de betão armado aconselha-se a utilização de ensaios não destrutivos, uma vez que permitem efetuar um diagnóstico com resultados positivos salvaguardando a integridade da estrutura. A norma EN 1504“Produtos e Sistemas para a proteção e reparação de estruturas de betão” estipula os procedimentos de execução, as características dos materiais mais adequados a cada tipo de projeto, assim como a divisão do seu encadeamento em 5 fases. O caso prático apresentado é um edifício de prestação de serviços municipais, tendo sido aplicado com o maior rigor possível as fases de inspeção, diagnóstico, deliberação e reparação. Foi efetuada uma fase de diagnóstico, de carácter visual assim como de caracterização física dos elementos estruturais em betão armado através de ensaios “in situ”. A estrutura avaliada apresenta debilidades e um estado de degradação acelerado, pelo que urge uma intervenção de reparação por forma a repor a estrutura com as características da sua conceção, salvaguardando a segurança das pessoas e bens.

Safety climate and its relationship with furniture companies’ safety performance and workers’ risk acceptance

This study aims to analyse the relationship between safety climate and the level of risk acceptance, as well as its relationship with workplace safety performance. The sample includes 14 companies and 403 workers. The safety climate assessment was performed by the application of a Safety Climate in Wood Industries questionnaire and safety performance was assessed with a checklist. Judgements about risk acceptance were measured through questionnaires together with four other variables: trust, risk perception, benefit perception and emotion. Safety climate was found to be correlated with workgroup safety performance, and it also plays an important role in workers’ risk acceptance levels. Risk acceptance tends to be lower when safety climate scores of workgroups are high, and subsequently, their safety performance is better. These findings seem to be relevant, as they provide Occupational, Safety and Health practitioners with a better understanding of workers’ risk acceptance levels and of the differences among workgroups.

Demolição de estruturas

A evolução das técnicas e dos materiais utilizados na atividade de construção, associado ao grau de degradação do parque habitacional, à necessidade de proteção ambiental e à segurança dos trabalhos, contribuíram para a evolução do setor da demolição de estruturas, no que respeita a métodos e técnicas de demolição. A referida evolução não se reflete nem se restringe aos equipamentos de demolição de pequena tonelagem, aos equipamentos de grande tonelagem ou aos equipamentos e acessórios específicos de demolição. A sensibilização à necessidade de planeamento, organização e gestão da obra, bem como a segurança de todas as operações é sem duvida, a maior evolução sofrida nos últimos anos neste setor. De acordo com a complexidade da demolição, é necessário adotar o método e as técnicas de demolição mais eficientes, garantindo e cumprindo com todos os requisitos legais em vigor.

Safety and immunogenicity of hepatitis B vaccine ButaNG in adults

Recombinant yeast-derived hepatitis B vaccine manufactured by Instituto Butantan was administered in two groups of adult volunteers (I, II) following two different schedules of immunization. In the first trial (10 mg doses and 0, 1, 3 months vaccination schedule) 106 individuals completed the full immunization program. The results of seroconversion by age group varied from 70 to 100% and the GMT from 46.5 to 124.9 mIU mL-1. In the second trial with 68 individuals (for dosage comparison and 0, 1, 6 months vaccination schedule) indicated that the vaccine formulated in 20 mg was more effective than in 10 mg. The adverse reactions observed in the vaccinees were less frequent than the ones previously found since the introduction of similar vaccines.
