Fundação de Amparo a Pesquisa do Estado de Minas Gerais / The course in distance learning can be customized taking in to account the specific characteristic of each student. This means that the learning environment has adaptativity. So, in order to develop adaptative systems of distance learning, it is necessary to consider the problems: instructional planning and the student model. The first problem allows to generate a specific sequence of content for each student and the second one provides the necessary information to cope with adaptativity. Planning techniques in Artificial Intelligence have been successfully used for determining the sequence of instructional actions. The Workflow technology has been used for the management of these systems. Then, this work presents an adaptative instructional planning and a student model based on Taxonomy of Educational Objectives and learning styles. / Muitos sistemas de educação à distância não levam em consideração características particulares do estudante, utilizam as mesmas estratégias pedagógicas e seqüencias de conteúdo para todos os estudante. No entanto, ambiente de educação à distância devem introduzir adaptatividade como uma das suas principais características. Para que isto seja possível, deve-se considerar os problemas de planejamento instrucional e definição modelo do estudante. O primeiro problema permite gerar uma sequência de conteúdo específica para cada estudante e o segundo problema prove informações necessárias para lidar com adaptatividade. Técnicas de planejamento em Inteligência Artificial têm sido utilizada para determinar a sequência de ações instrucionais. A tecnologia de Workflow têm sido utilizada para gerenciar estes sistemas. Por tanto, este trabalho apresentar um sequenciador de conteúdo adaptativo, que utiliza algoritmos genéticos e um modelo do estudante baseado taxionomia do objetivos educacionais e em estilos de aprendizagem. / Mestre em Ciência da Computação

La presente tesis tiene como objetivo la implementación de un Sistema Web para el Colegio de Notarios de Lima que será utilizado principalmente por el área de archivo de ex-Notarios en el proceso de Conclusión de Escrituras, proceso que consiste en culminar las firmas pendientes de las personas que intervienen en una Escritura Pública, en la actualidad este servicio se realiza de forma manual, es lento y engorroso. El sistema permitirá al cliente contar con una respuesta inmediata del estado actual de la Escritura Pública, costo del servicio y de esta manera decidir al instante si continua con el servicio solicitado, todo gracias a la base de datos de Escrituras Públicas digitalizadas, que han sido enviadas por los notarios que han cesado de su función. Además, agilizará el proceso de respuesta del Notario encargado respecto a los informes de Conclusión de Escritura enviados por el Encargado del archivo, la fecha de conclusión y notificación por correo electrónico. El sistema permitirá tener un mejor control del proceso actual gracias a que las tareas serán administradas y personalizadas según el perfil de cada usuario. Dicho sistema utiliza la tecnología web que dispone de información en tiempo real y está orientado a la búsqueda de documentos digitalizados. Por último el sistema podrá generar reportes respecto al servicio realizado en el área de archivo permitiendo a la Junta Directiva del Colegio de Notarios de Lima tomar decisiones para planificar estrategias de gestión. This thesis aims to implement a Web System for the College of Notaries of Lima which will be used mainly for the archive area of former notaries in the process of concluding Scriptures process of culminating the outstanding signatures people involved in a public deed, at present this service is performed manually, it is slow and cumbersome. The system will allow customers to have immediate feedback of the current state of the Deed, cost of service and thus decide immediately whether to continue with the requested service, thanks to the database Deeds digitized, which have been submitted by notaries who have ceased to function. In addition, it will streamline the process commissioned Notary response regarding Conclusion Writing reports sent by the File Manager, the completion date and email notification. The system will allow better control of the current process by which tasks are managed and customized to each user's profile. This system uses web technology that provides real-time information and is aimed at finding scanned documents. Finally the system can generate reports regarding the service performed in the area of file allowing the Board of the Association of Notaries of Lima make decisions to plan management strategies.

Against the background of increasing multidisciplinarity as well as the focus on quality, transparency and economic efficiency of medical services, clinical pathways (CPs) have been established as a promising tool at the organizational level in recent years. They are primarily intended to ensure an adequate description of the care processes and to manage the balance between best treatment practice and economic viability. CPs standardize the internal care services by explicating the institution-specific knowledge with regard to recommendations for action, service portfolio, organizational structures, infrastructure, etc. of a specific service provider. The development of hospital information systems (HIS) has so far been characterized by an evolutionary development of modules in the field of laboratory, radiology, nursing and picture archiving systems as well as in the area of administrative systems. As one result of this development, the HIS usually comprises a heterogeneous network of software systems of different types and manufacturers. However, the actual control of patients by means of evidence-based processes and integration of CPs into HIS was not addressed until the recent years, when HIS manufacturers started developing modules for CP modeling and workflow support. The objective of this thesis is to provide a holistic methodical support for the description of clinical pathways and their integration into a hospital information system to finally improve the compliance of daily care to standard process definitions. Therefore, conceptual models provide an adequate mean to describe and communicate complex matters in a comprehensible form as well as to configure IT systems due to their semi-formal nature. Hence, a first research thread investigates the question, how clinical pathways can be described adequately using conceptual models. This results in an iterative design of adequate modeling languages for clinical pathways. A second research thread further investigates the question, how conceptual models of clinical pathways can be used to configure process-oriented application systems in health care. This thread therefore describes the design of a model-based method, that enables a consecutive transformation of CPs into technical (workflow) specifications, based on the principles of the Model-Driven Architecture.

Nesse cenário, representado por alta complexidade e heterogeneidade, torna-se relevante o tratamento da proveniência de dados, que tem por objetivo descrever os dados que foram gerados ao longo da execução de um experimento científico e apresentar os processos de transformação pelos quais foram submetidos. Assim, a proveniência auxilia a formar uma visão da qualidade, da validade e da atualidade dos dados produzidos em um ambiente de pesquisa científica. O SciProv consiste em uma arquitetura cujo objetivo é interagir com sistemas de gerenciamento de Workflows científicos para promover a captura e a gerência dos metadados de proveniência gerados. Para esse propósito, o SciProv adota uma abordagem baseada em um modelo abstrato para a representação da proveniência. Esse modelo, denominado Open Provenance Model, confere ao SciProv a capacidade de prover uma infraestrutura homogênea e interoperável para a manipulação dos metadados de proveniência. Como resultado, o SciProv permite disponibilizar um arcabouço para consulta às informações de proveniência geradas em um cenário complexo e diversificado de e-Science. Mais importante, a arquitetura faz uso de tecnologia web semântica para processar as consultas aos metadados de proveniência. Nesse contexto, a partir do emprego de ontologias e máquinas de inferências, o SciProv provê recursos para efetuar deduções sobre os metadados de proveniência e obter resultados importantes ao extrair informações adicionais além daquelas que encontram-se registradas de forma explícita nas informações gerenciadas. / E-Science is characterized by manipulation of huge data set and large scale computing resources usage, often located in distributed environments. In this scenario, represented by high complexity and heterogeneity, it becomes important to treat data provenance, which aims to describe data that were generated during a scientific experiment execution and presents processes of transformation by which underwent. Thus, lineage helps to form a quality, validity and topicality vision of data produced in a scientific research environment. SciProv consists of an architecture that aims to interact with scientific workflows management systems for capture and manipulation of generated provenance metadata. For this purpose, SciProv adopts an approach based on an abstract model for representing the lineage. This model, called Open Provenance Model, provides to SciProv the ability to set up a homogeneous and interoperable infrastructure for handling provenance metadata. As a result, SciProv is able to provide a framework for query data provenance generated in a complex and diverse e-Science scenario. More important, the architecture makes use of semantic web technology to process metadata provenance queries. In this context, using ontologies and inference engines, SciProv provides resources to make inferences about lineage and to obtain important results in allowing the extraction of information beyond those that are registered explicitly from managed data.

Existem muitas pesquisas voltadas para o gerenciamento e execução de experimentos baseados em workflows.

Este cenário categoriza um ecossistema de experimentação científica. Para conduzir experimentos neste contexto, cientistas precisam de uma arquitetura flexível, extensível e escalável. Durante o processo de experimentação, informações valiosas podem ser perdidas e oportunidades de reutilização de recursos e serviços desperdiçadas, caso a arquitetura de ecossistema para e-Science não considere estes aspectos. Com o objetivo de tratar a flexibilidade, a extensibilidade e a escalabilidade de plataformas de ecossistemas, este trabalho apresenta uma arquitetura orientada a serviços apoiada por uma rede ponto a ponto, desenvolvida para tratar as etapas do ciclo de vida de um experimento científico. Este trabalho apresenta como contribuições uma arquitetura para ecossistemas de software científico, a implementação desta arquitetura, bem como a sua avaliação. / The conception of scientific workflows is a widely used approach in the context of eScience and scientific experimentation. There are many researches about the management and execution of experiments based on workflows. However, scientific experiments involve complex interactions between geographically distributed researchers, requiring the usage of large amount of data, services and distributed computing resources. This scenario categorizes a scientific experimentation ecosystem. In order to carry out experiments in this context researchers need an architecture for e-Science that supports flexibility, extensibility and scalability. During the experimentation process, valuable information can be unexploited and reusing opportunities of resources and services could be lost if the ecosystem architecture for e-Science does not consider previous mentioned requirements. In order to address the flexibility, extensibility and scalability of ecosystems platforms, this dissertation presents a service-oriented architecture supported by a peer-to-peer network. It was developed to support life-cycle stages of a scientific experiment. This work also presents, as contributions, an architecture to support experiments execution of scientific software ecosystems, the implementation of this architecture, as well as its evaluation.

A sua relevância no contexto desta dissertação é justificada por problemas clássicos neste domínio, como a falta de apoio para a composição de workflows científicos, dificuldade para reutilização de aplicações científicas, dificuldade de cooperação e comunicação entre as equipes de cientistas geograficamente distribuídas, entre outros. Abordagens como Linha de Produtos de Software - LPS têm sido empregadas para apoiar os cientistas na concepção de workflows científicos. Entretanto muitas informações relevantes sobre estas aplicações são perdidas ou mesmo não fornecidas pelos cientistas. Esta dissertação apresenta uma abordagem denominada Collaborative PL-Science, a qual é uma extensão de uma abordagem denominada PL-Science. Na abordagem PL-Science os cientistas possuíam apenas os artefatos persistidos no núcleo da LPS como componentes de trabalho. Com isso, o cientista desenvolvia um workflow científico baseado apenas em seu conhecimento sobre o domínio. Nenhum histórico, ou "rationale", era gerado neste ambiente, ficando todo o conhecimento sobre as funcionalidades dos artefatos, as experiências do cientista e as tomadas de decisões por conta do usuário. Como proposta de solução para estes problemas, a Collaborative PL-Science utiliza elementos de colaboração, tais como informações de percepção, contexto e um mecanismo de suporte à comunicação, em uma Linha de Produtos de Software Científico - LPSC. Com isso, espera-se gerar oportunidades de interação entre os pesquisadores e contextualizá-los em sua atividade de concepção de workflows científicos. / The need for collaboration in the scientific field has been discussed in some papers. Its relevance in the context of this thesis is justified by classical problems in this area, such as lack of support for the composition of scientific workflows, difficult reuse to scientific applications, difficulty of cooperation and communication among geographically distributed teams of scientists, among others. Approaches to Software Product Line - SPL have been used to support scientists in the design of scientific workflows. However many relevant information about scientific applications are lost or even not provided by scientists. This paper presents an approach named Collaborative PL-Science, which is an extension of an approach called PL-Science. In the PL-Science approach scientists had only the artifacts persisted in the core of the SPL as components of work. No historical or "rationale" was generated in this environment. Therefore all the knowledge about the functionalities of the artifacts, the experiences of the scientist and the decisions made are attributed to the user. As a proposed solution to these problems, the Collaborative PL-Science uses collaboration elements, such as awareness and context information and a mechanism to support communication in a Scientific Software Product Line - SSPL. Thus, it is expected to generate opportunities for interaction between researchers and contextualize them in their activity of designing scientific workflows.

[pt] Aplicações extensíveis por usuários finais representam uma proposta para tratar o problema de que é improvável que um software consiga atender a todas as necessidades específicas de cada usuário em um domínio. Uma das áreas de pesquisa de aplicações extensíveis é a de Programação por Usuários Finais ou End-User Programming (EUP). Investigações empíricas de EUP evidenciam a existência de práticas colaborativas relacionadas ao processo de extensão de aplicação, onde pessoas se comunicam com diversos objetivos: para ajudarem-se a resolver seus problemas com computação, para compartilhar extensões prontas ou construí-las conjuntamente. Nosso trabalho complementa essas investigações, contribuindo com um tratamento aprofundado e teoricamente motivado dos fenômenos de comunicação relacionados às práticas colaborativas observadas. Com base na teoria da Semiótica e na Engenharia Semiótica, propomos um modelo desses fenômenos, descrevendo sua estrutura e comportamento, permitindo assim uma melhor compreensão das questões relacionadas aos mesmos. De acordo com o modelo, projetamos uma linguagem computável para a representação de extensões de forma associada aos discursos das comunicações estudadas. / [en] Applications that are extensible by end-users represent a proposal to cope with the issue that it is improbable that a software will attend every specific need of each different user within a domain. One of the research areas approaching extensible applications is End-User Programming (EUP). EUP empirical investigations evidence the existence of collaborative practices related to the process of application extension. In these practices, people communicate with each other with various purposes: to help themselves deal with their problems regarding computing, to share ready-made extensions or to build extensions together. Our work complements these investigations by offering a deep and theoretically motivated treatment of the communication phenomena related to the observed collaborative practices. Based on Semiotics theory and Semiotic Engineering, we propose a model of these phenomena, describing its structure and behavior thus supporting a better understanding of the issues related to them. According to the model, we designed a computable language for the representation of extensions in association with corresponding communicative discourse.

More and more print jobs are delivered from customer to printer digitally over the Internet. Although Internet-based job delivery can be highly efficient, companies in the graphic arts and printing industry often suffer unnecessary costs related to this type of inflow of print jobs to their production workflows. One of the reasons for this is the lack of a well-defined infrastructure for delivering print jobs digitally over the Internet. This thesis presents INFLOW - a prototype for a print job delivery system for the graphic arts and printing industry. INFLOW is a web-based job delivery system that is hosted on an Internet-connected server by the organization receiving the print jobs. Focus has been on creating a system that is easy to use, highly customizable, secure, and easy to integrate with existing and future systems from third-party vendors. INFLOW has been implemented using open standards, such as XML and JDF (Job Definition Format). The requirements for ease-of-use, high customizability and security are met by choosing a web-based architecture. The client side is implemented using standard web technologies such as HTML, CSS and JavaScript while the serverside is based on J2EE, Java Servlets and Java Server Pages (JSP). Using a web browser as a job delivery client provides a highly customizable user interface and built in support for encrypted file transfers using HTTPS (HTTP over SSL). Process automation and easy integration with other print production systems is facilitated with CIP4’s JDF (Job Definition Format). INFLOW also supports"hot folder workflows"for integration with older preflight software and other hot folder-based software common in prepress workflows.

RED Digital Cinema is a rather new company that has developed a camera that has shaken the world of the film industry, the RED One camera. RED One is a digital cinema camera with the characteristics of a 35mm film camera. With a custom made 12 megapixel CMOS sensor it offers images with a filmic look that cannot be achieved with many other digital cinema cameras. With a new camera comes a new set of media files to work with, which brings new software applications supporting them. RED Digital Cinema has developed several applications of their own, but there are also a few other software supporting RED. However, as of today the way of working with the RED media files together with these software applications are yet in progress. During the short amount of time that RED One has existed, many questions has risen about what workflow is the best to use. This thesis presents a theoretical background of the RED camera and some software applications supporting RED media files. The main objective is to analyze RED material as well as existing workflows and find the optimal option.
