A Clinical Support System Based on Quality of Life Estimation

Quality of life is a concept influenced by social, economic, psychological, spiritual or medical state factors. More specifically, the perceived quality of an individual's daily life is an assessment of their well-being or lack of it. In this context, information technologies may help on the management of services for healthcare of chronic patients such as estimating the patient quality of life and helping the medical staff to take appropriate measures to increase each patient quality of life. This paper describes a Quality of Life estimation system developed using information technologies and the application of data mining algorithms to access the information of clinical data of patients with cancer from Otorhinolaryngology and Head and Neck services of an oncology institution. The system was evaluated with a sample composed of 3013 patients. The results achieved show that there are variables that may be significant predictors for the Quality of Life of the patient: years of smoking (p value 0.049) and size of the tumor (p value < 0.001). In order to assign the variables to the classification of the quality of life the best accuracy was obtained by applying the John Platt's sequential minimal optimization algorithm for training a support vector classifier. In conclusion data mining techniques allow having access to patients additional information helping the physicians to be able to know the quality of life and produce a well-informed clinical decision.

Crowdsourcing innovation: a strategy to leverage enterprise innovation

Innovation is recognized by academics and practitioners as an essential competitive enabler for any company to survive, to remain competitive and to grow. Investments in tasks of R&D have not always brought the expected results. But that doesn't mean that the outcomes would not be useful to other companies of the same business area or even from another area. Thus, there is much knowledge already available in the market that can be helpful to some and profitable to others. So, the ideas and expertise can be found outside a company's boundaries and also exported from within. Information, knowledge, experience, wisdom is already available in the millions of the human beings of this planet, the challenge is to use them through a network to produce new ideas and tips that can be useful to a company with less costs. This was the reason for the emergence of the area of crowdsourcing innovation. Crowdsourcing innovation is a way of using the Web 2.0 tools to generate new ideas through the heterogeneous knowledge available in the global network of individuals highly qualified and with easy access to information and technology. So, a crowdsourcing innovation broker is an organization that mediates the communication and relationship between the seekers - companies that aspire to solve some problem or to take advantage of any business opportunity - with a crowd that is prone to give ideas based on their knowledge, experience and wisdom. This paper makes a literature review on models of open innovation, crowdsourcing innovation, and technology and knowledge intermediaries, and discusses this new phenomenon as a way to leverage the innovation capacity of enterprises. Finally, the paper outlines a research design agendafor explaining crowdsourcing innovation brokering phenomenon, exploiting its players, main functions, value creation process, and knowledge creation in order to define a knowledge metamodel of such intermediaries.

Articulação de várias linguagens de programação/tecnologias no desenvolvimento aplicacional

O desenvolvimento aplicacional é uma área em grande expansão no mercado das tecnologias de informação e como tal, é uma área que evolui rápido. Os impulsionadores para esta característica são as comunicações e os equipamentos informáticos, pois detêm características mais robustas e são cada vez mais rápidos. A função das aplicações é acompanhar esta evolução, possuindo arquiteturas mais complexas/completas visando suportar todos os pedidos dos clientes, através da produção de respostas em tempos aceitáveis. Esta dissertação aborda várias arquiteturas aplicacionais possíveis de implementar, mediante o contexto que esteja inserida, como por exemplo, um cenário com poucos ou muitos clientes, pouco ou muito capital para investir em servidores, etc. É fornecido um nivelamento acerca dos conceitos subjacentes ao desenvolvimento aplicacional. Posteriormente é analisado o estado de arte das linguagens de programação web e orientadas a objetos, bases de dados, frameworks em JavaScript, arquiteturas aplicacionais e, por fim, as abordagens para definir objetivos mensuráveis no desenvolvimento aplicacional. Foram implementados dois protótipos. Um deles, numa arquitetura multicamada com várias linguagens de programação e tecnologias. O segundo, numa única camada (monolítica) com uma única linguagem de programação. Os dois protótipos foram testados e comparados com o intuito de escolher uma das arquiteturas, num determinado cenário de utilização.

A aceitação do registo de saúde electrónico pelos profissionais de saúde das instituições hospitalares

RESUMO: O Registo de Saúde Electrónico (RSE) detém uma importância vital para a melhoria dos cuidados e segurança do doente, para o acesso à sua informação, por profissionais de saúde, independentemente do momento e local de prestação dos cuidados clínicos, para a garantia da confidencialidade dos dados e para a redução da despesa dos serviços de saúde. É com base nesta sua importância que, no âmbito do Mestrado em Gestão da Saúde, da Escola Nacional de Saúde Pública, desenvolvemos um trabalho de investigação, que tem como objectivos descrever o “estado da arte” dos sistemas de informação em saúde e do RSE em Portugal, Europa e América do Norte, identificar a importância do RSE para os profissionais de saúde e para o doente, e avaliar a influência de determinados factores na aceitação do RSE por parte dos profissionais de saúde. Para certos autores, os factores condicionantes da aprovação do RSE podem ser: a idade, a formação, os conhecimentos informáticos, o tempo de exercício profissional e a compreensão dos benefícios do RSE por parte dos profissionais de saúde. Desta forma, elegemos estes factores para determinar se de facto são estes os que incitam a aceitação do RSE. O estudo foi dirigido a directores de serviço, médicos, enfermeiros e enfermeiroschefes, de cinco hospitais nacionais. Aos 20 participantes deste estudo foi aplicado um questionário, constituído por questões fechadas, questões factuais, de opinião e de informação. A metodologia utilizada foi do tipo descritivo e os dados foram analisados quantitativamente. Foi utilizado o coeficiente de Spearman para avaliar a existência de relação entre as variáveis, e com o seu uso foi possível depreender que: não há evidência de relação entre a idade e a aceitação do RSE; o tempo de exercício profissional não determina a aprovação do RSE; há evidência de relação entre os conhecimentos informáticos e a aceitação do RSE; a formação na área de digitalização de dados condiciona a aprovação do sistema; há evidência de relação entre a opinião dos profissionais de saúde acerca da actuação do RSE e a sua aceitação por parte destes.

How enterprise 2,0 firms take advantage of emergent social software platforms to manage knowledge

This research aims to provide a better understanding on how firms stimulate knowledge sharing through the utilization of collaboration tools, in particular Emergent Social Software Platforms (ESSPs). It focuses on the distinctive applications of ESSPs and on the initiatives contributing to maximize its advantages. In the first part of the research, I have itemized all types of existing collaboration tools and classify them in different categories according to their capabilities, objectives and according to their faculty for promoting knowledge sharing. In the second part, and based on an exploratory case study at Cisco Systems, I have identified the main applications of an existing enterprise social software platform named Webex Social. By combining a qualitative and quantitative approach, as well as combining data collected from survey’s results and from the analysis of the company’s documents, I am expecting to maximize the outcome of this investigation and reduce the risk of bias. Although effects cannot be universalized based on one single case study, some utilization patterns have been underlined from the data collected and potential trends in managing knowledge have been observed. The results of the research have also enabled identifying most of the constraints experienced by the users of the firm’s social software platform. Utterly, this research should provide a primary framework for firms planning to create or implement a social software platform and for firms willing to increase adoption levels and to promote the overall participation of users. It highlights the common traps that should be avoided by developers when designing a social software platform and the capabilities that it should inherently carry to support an effective knowledge management strategy.

m-SportGIS

Information technologies (ITs), and sports resources and services aid the potential to transform governmental organizations, and play an important role in contributing to sustainable communities development, respectively. Spatial data is a crucial source to support sports planning and management. Low-cost mobile geospatial tools bring productive and accurate data collection, and their use combining a handy and customized graphical user interface (GUI) (forms, mapping, media support) is still in an early stage. Recognizing the benefits — efficiency, effectiveness, proximity to citizens — that Mozambican Minister of Youth and Sports (MJD) can achieve with information resulted from the employment of a low-cost data collection platform, this project presents the development of a mobile mapping application (app) — m-SportGIS — under Open Source (OS) technologies and a customized evolutionary software methodology. The app development embraced the combination of mobile web technologies and Application Programming Interfaces (APIs) (e.g. Sencha Touch (ST), Apache Cordova, OpenLayers) to deploy a native-to-the-device (Android operating system) product, taking advantage of device’s capabilities (e.g. File system, Geolocation, Camera). In addition to an integrated Web Map Service (WMS), was created a local and customized Tile Map Service (TMS) to serve up cached data, regarding the IT infrastructures limitations in several Mozambican regions. m-SportGIS is currently being exploited by Mozambican Government staff to inventory all kind of sports facilities, which resulted and stored data feeds a WebGIS platform to manage Mozambican sports resources.

A indústria de defesa na cooperação Brasil-Portugal

The global dynamics of alliances are strongly determined by the level of cooperation among states. This cooperation can be embodied in various aspects, but the level of defense and security cooperation becomes usually more doctrinal and lasting. By the nature of sovereignty that instills in the bilateral relationship, cooperation at defense and security level can leverages other forms of cooperation. The circumstances and relational balance between Brazil and Portugal seem to evolve towards distancing opportunities, despite they are culturally and institutionally untainted. The economic dynamics, the strategic projection in global sustainability terms, the scale and ambition of Brazilian regional leadership, contrasts with the actual context of Portugal, distancing himself both on the stage where they operate. On the other hand, the historical and cultural roots, the language, the affinity of the peoples of CPLP and some opportunities for economic niches, trend to attract both countries. The condition of Portugal in NATO and Europe, coupled with the ability to export technical and human resources to value-added for Brazil, seems also to become approaching factors. On the balance of these dynamics, there is a set of exogenous factors (economic, external global relations matrix, regional stability, among others), which are not always controlled by any of both countries. These factors call for strong capacity for foresight analysis and decision making, with the inherent risk. There is cooperation vectors that are not apparently penalized by geographic distance, or by the difference of realities. Among these vectors we shall highlight synergies in technological niches, highly tradable goods and, mostly, using the domain of dual technologies. The thirteen niches herein identified are: Monitoring, Navigation, Command and Control, Electronics, Optoelectronics, Communication and remote sensing, Information Technologies, Flight Simulation, Specialized Training, Fiber Optic Sensors, Materials Engineering, Nanotechnology and Communications. Cumulating with identified opportunities in traditional relational framework, both countries are growing (in geography and economic terms) into the Atlantic, making it a central element in the bilateral approach. By being at the same time a growing stage of disputes and which stability tends to be threatened, it will be done an analysis of these synergistic vectors, superimposed on the impact on Atlantic securitization process.
