An approach to health and safety in E.U. forestry operations – Hazards and preventive measures

Forestry in general and logging in particular continue to be among the three most hazardous sectors in European countries. The aim of this article is to characterize health and safety problems and solutions in E.U. forestry operations, and particularly in Portuguese operations. Forest types, production, employment and ownership are used to characterize the forest sector. Forestry accidents and health problems data are mentioned. Typical hazards associated to the nature of logging operations are systematized. Preventive measures, focused on a wide spectrum of measures, making safety considerations an integral feature of all operational activities from planning to organization to execution and supervision of work are emphasized in this article.

O plano de deslocações urbanas e a resposta estratégica que falta aos PROTs e PDMs: A descentralização do planeamento do território e dos transportes

The sustainable urban mobility plan is the framework of planning and organisation of mobility system. It is a strategic and operational plan with consequences in the planning and organisation of territorial and transport systems. When it’s defining the principles and the objectives of sustainable development and when it’s working in the scenarios of modal shift more favourable to the alternative modes than the car, the planning and the organisation of territory will be integrated on the political of reduction of road circulation volumes, in the reduction of GEE, waste of space and time, in the improvement of quality of urban environment. The Urbanism Agencies and the Urban Transport Authorities will get their selves in the urban mobility plan, in territory scenarios development, mobility and transports, with the objective to understand the sustainable politics in the accessibilities which are available by the transportation bill. In Portugal, although the authorities are not yet working, the law (1/2009) recently approved in last December and published at the beginning of the year, they have the sustainable urban mobility plans forward in this strategy.

A high level e-maintenance architecture to support on-site teams

Emergent architectures and paradigms targeting reconfigurable manufacturing systems increasingly rely on intelligent modules to maximize the robustness and responsiveness of modern installations. Although intelligent behaviour significantly minimizes the occurrence of faults and breakdowns it does not exclude them nor can prevent equipment’s normal wear. Adequate maintenance is fundamental to extend equipments’ life cycle. It is of major importance the ability of each intelligent device to take an active role in maintenance support. Further this paradigm shift towards “embedded intelligence”, supported by cross platform technologies, induces relevant organizational and functional changes on local maintenance teams. On the one hand, the possibility of outsourcing maintenance activities, with the warranty of a timely response, through the use of pervasive networking technologies and, on the other hand, the optimization of local maintenance staff are some examples of how IT is changing the scenario in maintenance. The concept of e-maintenance is, in this context, emerging as a new discipline with defined socio-economic challenges. This paper proposes a high level maintenance architecture supporting maintenance teams’ management and offering contextualized operational support. All the functionalities hosted by the architecture are offered to the remaining system as network services. Any intelligent module, implementing the services’ interface, can report diagnostic, prognostic and maintenance recommendations that enable the core of the platform to decide on the best course of action.

Gestão de bloco operatório : modelos de gestão e monitorização

RESUMO - A consciência de uma necessidade clara em rentabilizar a capacidade instalada e os meios tecnológicos e humanos disponíveis no Bloco Operatório e face ao imperativo de um cabal desempenho e de uma adequada efectividade nestes serviços levou-nos à realização deste estudo. Objectivos: O trabalho de projecto centrou-se em quatro objectivos concretos: Elaboração de uma grelha de observação de Modelos de Gestão de Bloco Operatório; Observação de seis Modelos de Gestão de Blocos Operatórios em experiências nacionais e in-loco, de acordo com a grelha de observação; Avaliação da qualidade gestionária na amostra seleccionada à luz dos modelos existentes; Criação de uma grelha de indicadores para a monitorização e avaliação do Bloco Operatório. Metodologia: Na elaboração da grelha de observação dos Blocos Operatórios recorremos a um grupo de peritos, à bibliografia disponível e à informação recolhida em entrevistas. Aplicámos a grelha de observação aos seis Blocos Operatórios e analisámos as informações referentes a cada modelo com a finalidade de encontrar os pontos-chave que mais se destacavam em cada um deles. Para a elaboração da grelha de indicadores de monitorização do Bloco Operatório realizámos uma reunião recorrendo à técnica de grupo nominal para encontrar o nível de consenso entre os peritos. Resultados: Criámos uma grelha de observação de Modelos de Gestão de Bloco Operatório que permite comparar as características de gestão. Esta grelha foi aplicada a seis Blocos Operatórios o que permitiu destacar como elementos principais e de diferenciação: o sistema de incentivos implementado; o sistema informático, de comunicação entre os serviços e de débito directo dos gastos; a existência de uma equipa de gestão de Bloco Operatório e de Gestão de Risco; a importância de um planeamento cirúrgico semanal e da existência de um regulamento do Bloco Operatório. Desenhámos um painel de indicadores para uma monitorização do Bloco Operatório, de onde destacamos: tempo médio de paragem por razões técnicas, tempo médio de paragem por razões operacionais, tempo médio por equipa e tempo médio por procedimento. Considerações finais: Os Blocos Operatórios devem ponderar a existência das componentes mais importantes dos Modelos, bem como recolher exaustivamente indicadores de monitorização. A investigação futura deverá debruçar-se sobre a relação entre os indicadores de monitorização e os Modelos de Gestão, recorrendo à técnicas de benchmarking. -------------------ABSTRACT - This study was driven by the need to optimise available capacity, technology and human resources in the Operating Room and to address the corresponding goals of adequate performance and effectiveness. Objectives: This project focuses on four specific objectives: development of an observation grid of operating room management models; in-loco observation and documentation of six national operating room, according to the grid; assess the quality of management in the selected sample relative to existing management models; create a set of indicators for monitoring and evaluating operating rooms. Methodology: The design of the observation grid was based on experts’ consultation, a literature survey and information gathered in various interviews. The observation grid was applied to six operating rooms and the information for each management model was analysed in order to find its key characteristics. We used the Nominal Group Technique in order to develop a set of indicators for monitoring and evaluating operating rooms. Results: An observation grid was created for operating rooms management models, which allowed comparing management characteristics. This grid was applied to six operating rooms allowing disentangle its main features and differentiating characteristics: implementation of incentive systems; IT systems including information flow between services; inventory and expense management; existence of a management team and effective risk management; importance of weekly planning and regulations. We designed a set control indicators, whose major characteristics are the following: the average down time due to technical reasons, the average down time due to operational reasons, the average time per team and the average time per procedure. Final Conclusions: Operating rooms should consider the most relevant characteristics of management models and collect exhaustive information on control indicators. Future research should be devoted to assessing the operating room performance according to management models, using control indicators and benchmarking techniques.
