Internet Geography: Spaces of Innovation

Information Society plays an important role in all kinds of human activity, inducing new forms of economic and social organization and creating knowledge. Over the last twenty years of the 20th century, large investments in telecommunication networks were made to approach economies and put an end to the asymmetries. The most isolated regions were the beneficiaries of this new technological investment’s wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services, products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical/real space, location is defined by two or three geographical co-ordinates. In the network/virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. Internet Geography is one example. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to regional development studies, and at the same time. The IP address distribution of Country Code Top Level Domains (.pt for Portugal) could show the same economic patterns, reflecting territorial inflexibility or, by opposition, new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to analyse the info-structural dynamic and economic development of a territory, especially at regional level. At the same time it shows that information technologies are essential to innovation and competitive advantage.

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.

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.

Percepção do estado de saúde da pessoa idosa institucionalizada

RESUMO: O envelhecimento da população portuguesa é um facto. Esta alteração da estrutura demográfica exige o investimento no conhecimento científico para que se conheçam as consequências a nível, económico, social, cultural, biológico, físico e, principalmente, a nível da saúde. Isto porque, é emergente que a sociedade tenha capacidade para responder às necessidades específicas das pessoas neste estádio de vida, tendo sempre por base o conceito de qualidade de vida. Este estudo teve como objectivo avaliar a percepção do estado de saúde da pessoa idosa institucionalizada. Foram nove as instituições participantes, denominadas por lares de idosos de residência permanente, onde se contou com uma amostra de 75 indivíduos entre os 66 e 100 anos, de ambos os sexos. Foram recolhidos dados através de uma caracterização sócio-demográfica, através do Mini Mental State e através do Questionário de auto-avaliação da saúde e do bem-estar físico (de Fonseca e Paúl, 1999). Os dados obtidos foram trabalhados numa perspectiva de estatística descritiva e estatística inferencial, nomeadamente com a análise do coeficiente de Spearman. A partir desta análise determinou-se que: a grande maioria da amostra designa como “aceitável” ou “fraca” a sua percepção da saúde, em geral; os dados sócio-demográficos, e a instituição a que cada indivíduo pertence não têm relação com a percepção do estado de saúde destas pessoas; existe relação significativa entre a percepção do estado de saúde das pessoas idosas institucionalizadas e a saúde dos seus pares, essencialmente quando se abordam itens relacionados com aspectos físicos; no que concerne aos hábitos de vida, não existe relação entre a percepção do estado de saúde das pessoas idosas e os hábitos tabágicos e os hábitos alcoólicos. Os dados obtidos nem sempre são os dados que se esperavam efectivamente, porém fazem sentido ao serem consolidados com a teoria.--------ABSTRACT: The aging of the Portuguese population is a reality. It is imperative that society has the capacity to face the specific necessities of those who are in this phase of their lives. Therefore, this change in the demographics requires investment in scientific knowledge in order to know the consequences at levels such as: the economic, social cultural, biological and physical, mainly related to health. The main purpose of this study has been to evaluate the perceptions of elderly people concerning their health conditions. There were nine institutions involved, which are referred to as nursing homes, and a sample of 75 people between 66 and 100 years-old, from both genders, cooperated. Data has been collected through social-demographic, Mini Mental State and also through the questionnaire of the self-evaluation of health and physical well-being (from Fonseca and Paúl, 1999). The obtained data was worked within a perspective of descriptive/ inference statistic. From this analysis, it was determined that the great majority of the sample describes their perception of health as “acceptable” or “weak”, in general; the social-demographic information and the institution to where each person belongs do not show a connection with their perception of their health condition; however, there seems to be a significant relation between an institutionalized elderly person´s perception of their health condition and their spouse’s health, mainly when related to physical issues. In as far as life styles are concerned, do not show a connection between elderly people’s perception of health and smoking habits and alcohol habits. The obtained data does not always match expectations; nevertheless they make sense when being complemented by the theory.
