ESEIG Mobile: an m-learning approach in a superior school

In recent years, mobile learning has emerged as an educational approach to decrease the limitation of learning location and adapt the teaching-learning process to all type of students. However, the large number and variety of Web-enabled devices poses challenges for Web content creators who want to automatic get the delivery context and adapt the content to mobile devices. In this paper we study several approaches to adapt the learning content to mobile phones. We present an architecture for deliver uniform m-Learning content to students in a higher School. The system development is organized in two phases: firstly enabling the educational content to mobile devices and then adapting it to all the heterogeneous mobile platforms. With this approach, Web authors will not need to create specialized pages for each kind of device, since the content is automatically transformed to adapt to any mobile device capabilities from WAP to XHTML MP-compliant devices.

A New Approach in the Design of Air Stripping Columns for the Treatment of Groundwater Contaminated With Volatile Organic Compounds

Volatile organic compounds are a common source of groundwater contamination that can be easily removed by air stripping in columns with random packing and using a counter-current flow between the phases. This work proposes a new methodology for column design for any type of packing and contaminant which avoids the necessity of an arbitrary chosen diameter. It also avoids the employment of the usual graphical Eckert correlations for pressure drop. The hydraulic features are previously chosen as a project criterion. The design procedure was translated into a convenient algorithm in C++ language. A column was built in order to test the design, the theoretical steady-state and dynamic behaviour. The experiments were conducted using a solution of chloroform in distilled water. The results allowed for a correction in the theoretical global mass transfer coefficient previously estimated by the Onda correlations, which depend on several parameters that are not easy to control in experiments. For best describe the column behaviour in stationary and dynamic conditions, an original mathematical model was developed. It consists in a system of two partial non linear differential equations (distributed parameters). Nevertheless, when flows are steady, the system became linear, although there is not an evident solution in analytical terms. In steady state the resulting ODE can be solved by analytical methods, and in dynamic state the discretization of the PDE by finite differences allows for the overcoming of this difficulty. To estimate the contaminant concentrations in both phases in the column, a numerical algorithm was used. The high number of resulting algebraic equations and the impossibility of generating a recursive procedure did not allow the construction of a generalized programme. But an iterative procedure developed in an electronic worksheet allowed for the simulation. The solution is stable only for similar discretizations values. If different values for time/space discretization parameters are used, the solution easily becomes unstable. The system dynamic behaviour was simulated for the common liquid phase perturbations: step, impulse, rectangular pulse and sinusoidal. The final results do not configure strange or non-predictable behaviours.

Interdisciplinaridade como estratégia para um cuidado de saúde culturalmente competente em serviço de infeciologia

A interdisciplinaridade é uma estratégia para a qualidade dos cuidados de saúde. A consciência das diferenças dentro dos grupos homogêneos favorecem ações mais congruentes, como proposta de superação da dificuldade de união entre a ciência e a complexidade em saúde. Sugere um repensar sobre a fragmentação do conhecimento na saúde e uma reflexão que fortaleça as parcerias entre os múltiplos profissionais com enfoque em melhores condições de saúde e vida da população. Neste artigo, objetivou-se descrever a abordagem interdisciplinar no processo de cuidar culturalmente competente a pessoa vivendo com HIV; e compreender, na percepção do enfermeiro, a relação entre a interdisciplinaridade e o processo de cuidar culturalmente competente. O estudo foi do tipo descritivo e exploratório, realizado em serviços de infeciologia referência em Portugal. As informações foram coletadas por observações participantes do contexto social e durante as reuniões de equipa. Também foram realizadas 18 entrevistas semiestruturadas com os enfermeiros dos serviços. Todos os preceitos éticos do estudo com seres humanos foram respeitados. Os dados foram tematizados com suporte da análise de conteúdo de Bardin (2011) e apresentam-se como dois temas: Implicações práticas do trabalho interdisciplinar e Facilidades/dificuldades no cuidar interdisciplinar. Estas temáticas demonstraram a importância da atitude dialógica entre profissionais-instituição-utente, num contexto de confronto de ideias e conhecimentos essenciais para aprimorar a qualidade dos cuidados em saúde por meio da maestria cultural.

Digital storytelling: emotions in higher education

The results presented in the article are part of a wider PhD project developed under the Doctoral program in Multimedia in Education from the University of Aveiro. The project, which sought to understand student ID in Higher education through the use of Digital Storytelling, was made possible through the Doctoral Grant awarded by Fundação para a Ciência e Tecnologia (FCT).
