Most of the traditional software and database development approaches tend to be serial, not evolutionary and certainly not agile, especially on data-oriented aspects. Most of the more commonly used methodologies are strict, meaning they’re composed by several stages each with very specific associated tasks. A clear example is the Rational Unified Process (RUP), divided into Business Modeling, Requirements, Analysis & Design, Implementation, Testing and Deployment. But what happens when the needs of a well design and structured plan, meet the reality of a small starting company that aims to build an entire user experience solution. Here resource control and time productivity is vital, requirements are in constant change, and so is the product itself. In order to succeed in this environment a highly collaborative and evolutionary development approach is mandatory. The implications of constant changing requirements imply an iterative development process. Project focus is on Data Warehouse development and business modeling. This area is usually a tricky one. Business knowledge is part of the enterprise, how they work, their goals, what is relevant for analyses are internal business processes. Throughout this document it will be explained why Agile Modeling development was chosen. How an iterative and evolutionary methodology, allowed for reasonable planning and documentation while permitting development flexibility, from idea to product. More importantly how it was applied on the development of a Retail Focused Data Warehouse. A productized Data Warehouse built on the knowledge of not one but several client needs. One that aims not just to store usual business areas but create an innovative sets of business metrics by joining them with store environment analysis, converting Business Intelligence into Actionable Business Intelligence.

A dissertação descreve o levantamento e otimização do processo de fabrico de uma peça plástica para um automóvel. A otimização deste processo produtivo tem em vista a rentabilização de recursos humanos, a redução de custos associados e a redução de atividades ao longo do processo, tais como armazenamento de produto semiacabado, uma vez que este deixa de existir, a eliminação de fluxos logísticos e a eliminação do posto de montagem de componentes desta peça. A metodologia utilizada neste projeto centra-se na aplicação de ferramentas que permitem a análise e melhoria de processos produtivos, tais como o diagrama de processo, o diagrama spaghetti, o PDCA, a cronometragem dos tempos por tarefa e a aplicação de uma heurística para o balanceamento do futuro posto de trabalho da peça em estudo. O diagrama de processo, o diagrama de spaghetti e a cronometragem dos tempos por tarefas mostraram o estado atual do processo produtivo. Da análise do atual estado verifica-se que existe muito desperdício de mão-de-obra nas duas estações de trabalho, injeção e montagem. A eliminação do posto de trabalho exclusivo para montagem e junção dos processos de injeção e montagem no mesmo posto de trabalho, com a aplicação de uma heurística para balanceamento do novo posto de trabalho, demonstra que os ganhos são muito significativos. A aplicação do ciclo PDCA, na base da qual está a elaboração de um plano de ações, tornará esta mudança possível e bem-sucedida. A intenção deste projeto é demonstrar que o estado atual pode sempre ser melhorado se se usarem as ferramentas corretas para análise e proposta de melhorias que trarão ganhos à empresa a curto prazo. Usando esta sugestão, a empresa poderá dar início a um novo ciclo em que o espírito de melhoria esteja presente todos os dias em toda a organização.

In this paper, we introduce an innovative course in the Portuguese Context, the Master's Course in “Integrated Didactics in Mother Tongue, Maths, Natural and Social Sciences”, taking place at the Lisbon School of Education and discussing in particular the results of the evaluation made by the students who attended the Curricular Unit - Integrated Didactics (CU-ID). This course was designed for in-service teachers of the first six years of schooling and intends to improve connections between different curriculum areas. In this paper, we start to present a few general ideas about curriculum development; to discuss the concept of integration; to present the principles and objectives of the course created as well as its structure; to describe the methodology used in the evaluation process of the above mentioned CU-ID. The results allow us to state that the students recognized, as positive features of the CU-ID, the presence in all sessions of two teachers simultaneously from different scientific areas, as well as invitations issued to specialists on the subject of integration and to other teachers that already promote forms of integration in schools. As negative features, students noted a lack of integrated purpose, applying simultaneously the four scientific areas of the course, and also indicated the need to be familiar with more models of integrated education. Consequently, the suggestions for improvement derived from these negative features. The students also considered that their evaluation process was correct, due to the fact that it was focused on the design of an integrated project for one of the school years already mentioned.

A Learning Management System (LMS) plays an important role in any eLearning environment. Still, the LMS cannot afford to be isolated from other systems in an educational institution. Thus, the potential for interoperability is an important, although frequently overlooked, aspect of an LMS system. In this chapter we make a comparative study of the interoperability features of the most relevant LMS in use nowadays. We start by defining a comparison framework, with systems that are representative of the LMS universe, and interoperability facets that are representative of the type integration with other broad classes of eLearning systems. For each interoperability facet we categorize and identify the most representative remote systems, we present a comprehensive survey of existing standards and we illustrate with concrete integration scenarios. Finally, we draw some conclusions on the status of interoperability in LMS based on our study.

Existent computer programming training environments help users to learn programming by solving problems from scratch. Nevertheless, initiating the resolution of a program can be frustrating and demotivating if the student does not know where and how to start. Skeleton programming facilitates a top-down design approach, where a partially functional system with complete high level structures is available, so the student needs only to progressively complete or update the code to meet the requirements of the problem. This paper presents CodeSkelGen - a program skeleton generator. CodeSkelGen generates skeleton or buggy Java programs from a complete annotated program solution provided by the teacher. The annotations are formally described within an annotation type and processed by an annotation processor. This processor is responsible for a set of actions ranging from the creation of dummy methods to the exchange of operator types included in the source code. The generator tool will be included in a learning environment that aims to assist teachers in the creation of programming exercises and to help students in their resolution.

RESUMO - É reconhecido o impacto negativo e prejudicial que o tempo de espera tem para radioterapia sobre o controlo tumoral e a taxa de sobrevida, bem como a importância de estabelecer tempos máximos para o início do tratamento, de forma a garantir o cumprimento de uma boa prática. O presente projecto de investigação tem o objectivo de construir e validar uma grelha de observação, como instrumento de recolha de dados, que se pretende no futuro aplicar, de forma a poder contribuir para o estudo sobre o tempo de espera para radioterapia em Portugal. Para alcançar o objectivo proposto, optou-se pela metodologia usada por Drinkwater e Williams na re-auditoria efectuada no Reino Unido pelo Royal College of Radiologists, em 2007, sobre os tempos de espera para radioterapia. A grelha de observação elaborada foi baseada na grelha utilizada por Drinkwater e Williams, na revisão da literatura, e tendo em consideração a realidade portuguesa. Após a análise das respostas dos peritos, ao questionário de avaliação e adequação do instrumento à realidade portuguesa, parece existir concordância na adequação do instrumento, o que nos permite afirmar a possibilidade da aplicação do mesmo nos centros de radioterapia de Portugal. --- --------------------------------ABSTRACT - It is recognized the negative impact that radiotherapy waiting time have in tumour control and survival, as well the importance of establish maximum waiting times for the start of the treatment, in the sense to guarantee a good practice. The present investigation project aim is to build and validates a data collection tool, which pretends to apply in the future, in the sense to contribute for the study of the radiotherapy waiting time in Portugal. To accomplish the project aim, we chose the method used by Drinkwater and Williams in the re-audit performed in United Kingdom for the Royal College of Radiologists, in 2007, about the radiotherapy waiting time. The data collection tool built was based on the data collection tool used by Drinkwater and Williams, on the literature review and taking in account the Portuguese reality. After the analyse of the experts answers, it seems to exist agreement about the adequacy of the data collection tool, which allow us to claim the possibility of the tool application at radiotherapy centres, in Portugal.
