During this treatment the professionals should communicate and collaborate to solve the patient diseases. In a local study in the public health at Blumenau city, we have observed that there is a lack of communication and collaboration among these professionals. This lack of communication affects the multidisciplinary treatment. This problem occurs due to different geographic position in doctors offices and due to different availability of each professional. In this context, this work has realized an action research involving the Elderly Care Center of Blumenau city to help the development of a system that allows multidisciplinary treatment. Blumenau has a health system called PRONTO. However, this system does not allow the collaboration among health professionals during the healthcare. Thus, this work includes the multidisciplinary treatment in the actual system and allows the collaboration among the health professionals. We used the participatory design method to design the multidisciplinary treatment and its interface, in order to involve the professionals in the development. The Scenario Based Evaluation was used to evaluate the developed system. This method allows to identify the important scenarios to perform the tasks. The design, development and evaluation of multidisciplinary treatment occurred in four steps of action research. We conclude that the proposed system allows the multidisciplinary treatment in collaborative way. The system also decreased the lack of communication and collaboration problems. / O tratamento multidisciplinar na área da saúde é o tratamento prestado a pacientes que dependem da atenção de profissionais de diferentes áreas. Durante este tratamento, os profissionais devem se comunicar e colaborar para solucionar o problema do paciente. Em estudos realizados na rede pública da cidade de Blumenau, observou-se que existe falta de comunicação e colaboração entre estes profissionais prejudicando o atendimento multidisciplinar. O problema ocorre principalmente devido aos diferentes locais de trabalho e diferentes horários de atendimento destes profissionais de saúde. Nesse contexto, este trabalho realizou uma pesquisa-ação envolvendo o Centro de Saúde do Idoso da cidade de Blumenau, para auxiliar na construção de um sistema que permita o tratamento multidisciplinar. Blumenau possui um sistema de saúde denominado PRONTO, porém ele não permite a colaboração entre os profissionais de saúde durante o tratamento de um paciente. Sendo assim, o trabalho pretende incluir o atendimento multidisciplinar no sistema atual permitindo a colaboração entre esses profissionais. O método de design participativo foi utilizado para a construção do módulo multidisciplinar e de sua interface, com intuito de envolver os profissionais em sua construção e identificar as tarefas a serem realizadas. O método Scenario Based Evaluation foi utilizado para avaliar o sistema. Este método permite a identificação de cenários importantes para a realização das tarefas dos profissionais. A construção e avaliação do atendimento multidisciplinar desenvolvido ocorreu dentro de quatro ciclos de pesquisa-ação. Após o término da pesquisa-ação, podese concluir que as funcionalidades projetadas permitem o atendimento multidisciplinar de forma colaborativa com uma ferramenta computacional, reduzindo os problemas referentes à falta de comunicação e de colaboração entre os profissionais de saúde.

Workflow systems orchestrate various business tasks to attain an objective. Web services can be leveraged to handle individual tasks. Before anyone intends to leverage service components, it is imperative and essential to evaluate the trustworthiness of these services. Therefore, choosing a trustworthy service has become an important decision while designing a workflow system. Trustworthiness can be defined as the likelihood of a service functioning as it is intended. Selection of a service that satisfies business goals involves collecting relevant information such as security mechanisms, reliability, performance and availability. It is important to arrive at total trustworthiness, which incorporates all of the above mentioned multi-facet values relevant to a service. These values can be gathered and analyzed to derive the total trustworthiness of a service. Measuring trustworthiness of a service involves arriving at a suitable value that would help an end-user make a decision for the given business settings. The primary focus of this thesis is to gather relevant details and measure trustworthiness based on inputs provided by the user. A conceptual model was developed after extensive literature review to identify factors that influence trustworthiness of a service. A mechanism was created to gather concept values for a given service and utilize those values to calculate trustworthiness index value. A proof-of-concept prototype was also developed. The prototype is a web-based application that implements the mechanism to measure the trustworthiness of the service. The prototype was evaluated using a scenario-based analysis method to demonstrate the utility of the trustworthiness mechanism using three different scenarios. Results of the evaluation shows that trustworthiness is a multidimensional concept, the relevant conceptual values can be collected, a trustworthiness index value can be calculated based on the gathered concepts, and a trustworthiness index can be interpreted to select the most relevant service for a given requirement.

<p>This master’s thesis consists of a scenario-based evaluation of an IT-security assessment method known as the eXtendedMethod for Assessment of System Security (XMASS), as well as an assessment of a real-world network using the softwareimplementation of this method known as the Security AssessmeNT Application (SANTA).This thesis also describes a number of improvements made to the software implementation, some which could also be addedto the method itself. These were performed during the preparation of the assessment but had no effect on the outcome.The evaluation showed that the method and implementation contained a number of flaws in the way the filtering effect ofthe traffic mediators of a network, such as network-based firewalls, was implemented. When it comes to the assessment ofthe real-world network it was seen that the network, given the supplied information regarding the software and hardwaresetup of its entities, appeared to be sufficiently secure to handle the transmission of data at the lowest classification level(Restricted). However, as with almost all security assessments, this does not mean that the network is guaranteed to besecure enough; it just indicates that, given the information specified, the network has the potential of being sufficientlysecure.The main conclusion of this thesis is that the way XMASS and SANTA calculates the effect of filtering traffic mediatorsshould be looked into and improved to increase the usability of the tool. The method can however still be used in its currentstate, but requires the individual(s) performing the assessment to be aware of the drawbacks of the current implementationand thus compensate for these when producing the input for the assessment method.</p>
