In this thesis, I present a framework for bridging the concepts of Social Networks and eLearning Learning Management Systems (LMSs) by finding elements and entities common to both systems, and eliminating these common elements to form an LMS Gadget which can hypothetically be used to extend any Social Network with an API that exposes User and User-Group information so that it also has the functionality of an LMS. I will also include a history of these systems, and a concrete example of such a unification. Finally, I will explore the application of the LMS Gadget to any Web Portal System that exposes User and Group management through an Application Programming Interface (API). This is an application that I conceived of, designed, and did the large majority of the programming for (with assistance on some data access routines to help meet an April 2008 conference deadline). Graphic design was provided by Amos Rowsell of Udutu Learning Systems (a private company for which I have held the role of Lead Developer since November 2005).

Australia's tertiary educational environment is changing; in the past decade, it has faced a new set of challenges and pressures (Cunningham et al., 1998) that are encroaching on the traditional definitions of what higher education is. These challenges often dictate the directions in which the tertiary education environment evolves into. Within the framework of institutional reforms, the adopted policies are often the best indicators of that transition. Flexible delivery or learning has been espoused as a means of meeting and mediating some of those challenges. With their emphasis on catering to the needs and expectations of the consumer in a consumerist society, flexible policies are becoming the norm in most institutes of higher learning. However, of interest within the structure of the flexible delivery approach is the development of learner management systems (LMS). The question is what are learner management systems? What do they represent and what do they offer to the learner that differentiates it from the traditional forms of learning? In its basic form, a learner management system is essentially a series of processes that are developed and organised so as to efficiently provide the learner with the required access and interaction required to facilitate his or her learning. However, what are the benefits of being aware of the capabilities and limitations afforded by such approaches? How does it contribute to the process of teaching and learning in the context of higher education? The effectiveness of how these learner management systems are used in context to its application in multimedia programmes is of importance. Institutions are progressively introducing similar learning systems into their delivery framework. The question as to whether a singular adaptive system or a customised option remains to be tested.

The diploma thesis deals with possibilities and usage of e-learning in the field of education of employees of Ministry of Interior through the Police schools. Its aim is to analyze e-learning training at the Police College and Secondary Police School of the Ministry of the Interior in Prague, to identify opportunities for improvement resulting from the practical experience with a chosen e-learning course, to create corrective improving measures and the verification in practice. The theoretical part of the thesis is focused on the explanation of the concept of e-learning, the historical development of this phenomenon, the familiarization with the forms and last but not least with its advantages and disadvantages. The practical part is mapping the level of e-learning and its forms at the Police College and Secondary Police School of the Ministry of Interior in Prague. It examines the impact of e-learning on increasing the qualifications of employees and their attitude towards this form of education. It also describes the practical experience with the chosen course, including the identification of opportunities for improvement, and their verification by the participants through a questionnaire survey. On the basis of this experience some measures were suggested and subsequently verified in practice.

Digital technologies have been present in the educational environment in the Czech Republic and other countries for many years. Not only are they becoming a relatively frequent means of making education more attractive, but they also have a great potential for improving methods of illustration in areas difficult to visualize, such as human biology and anatomy. The presented thesis is divided into the theoretical and practical part. The theoretical part summarizes available specialized literature covering the bases for utilizing digital technologies in the practice of teaching; maps out the process of implementing digital technologies into schools in the Czech Republic; and last but not least, describes key elements and methods of teaching with the help of digital technologies. The practical part introduces the results of a survey which took the form of a mixed methods research among elementary and high school pupils, teachers, and students of Teaching Preparation programs. In the final discussion, the amassed data are compared to some of the relevant past surveys conducted by various subjects. In addition, the practical part also includes model activities for using digital technologies in human biology teaching; a description of their pilotage; and a critical reflection on the process.

Ce travail de thèse porte sur la modélisation des phénomènes de propagation affectant les signaux de navigation par satellite en environnement urbain dense avec une focalisation particulière sur les multitrajets et l'aspect large bande du canal de propagation espace/Terre. Le simulateur de canal pseudo temps-réel développé, SCHUN (Simplified CHannel for Urban Navigation), repose sur une approche hybride physico-statistique. La composante statistique de la modélisation permet essentiellement de générer une ville virtuelle à partir de distributions de bâtiments connues. Le reste de la modélisation s'appuie sur une approche physique simplifiée où les interactions ondes électromagnétiques/ville virtuelle reposent d'une part sur un modèle de macro-diffusion à l'échelle des façades, (3CM (Three Component Model)), et d'autre part sur un modèle physique de masquage du trajet direct par les bâtiments. Les principales méthodes numériques sous-jacentes sont l'optique physique et la théorie uniforme de la diffraction. Le simulateur de canal SCHUN ouvre aujourd'hui des perspectives intéressantes pour la modélisation large bande du canal de propagation espace/Terre. Optimisé pour des temps de calcul raisonnables, alliant une composante statistique à une composante physique simplifiée, ce simulateur a été conçu et validé par des mesures expérimentales pour répondre à des besoins de simulation des systèmes à diversité de satellite, diversité de réception, diversité de polarisation ou encore diversité de fréquence pour des applications de navigation par satellite. / This PhD work deals with land mobile satellite channel modelling and addresses the specific issue of satellite navigation systems in urban environments with a particular focus on multipath modelling and wide-band representation of the channel. The developed land mobile satellite channel simulator, SCHUN (Simplified CHannel for Urban Navigation), is based on a hybrid physical-statistical approach satisfying fast computation requirements. The statistical component of the modelling is mainly used during the virtual city synthesis step based on known statistical distributions of building height and street width. The rest of the modelling comes from deterministic methods using simplified electromagnetic interaction models reproducing building macro-scattering (3CM model (Three Component Model)) and building blockage of the direct path. The main underlying electromagnetic methods are the physical optics and the uniform theory of diffraction. The SCHUN simulator now opens interesting perspectives for the modelling of wide-band land mobile satellite propagation channel in dense urban environments. Optimised for pseudo real-time constraints, it uses both physical and statistical approaches. Furthermore, the SCHUN simulator has been designed and validated against measurements to answer specific needs of satellite diversity, receiving diversity, polarisation diversity or frequency diversity for satellite navigation applications.

Para isso, o uso de recursos multimídia como áudio, imagens, vídeos e objetos de realidade virtual, inseridos no conteúdo oferecido, permite um aprendizado mais agradável e mais atrativo para o aluno que usa o LMS com estes recursos. Devido à grande dificuldade de se manipular, inserir e recuperar tais objetos multimídia e de realidade virtual nos conteúdos gerenciados por LMS, sentiu-se a necessidade de especificar e implementar um servidor de dados que facilitasse tal manipulação integrada a um LMS O objetivo principal deste trabalho é desenvolver um Servidor de Dados para manipulação e gerenciamento de objetos multimídia e objetos de realidade virtual em um LMS, tendo sido escolhido como estudo de caso o LMS AMADEUS-MM. O referido servidor tem como finalidade principal o gerenciamento de conteúdo multimídia em ambientes virtuais de ensino, com particular eficiência no armazenamento e transferência de dados multimídia (imagens, áudios, vídeos) e mundos de realidade virtual. O Servidor de Dados Multimídia provê uma estrutura de dados para o gerenciamento do conteúdo multimídia em um ambiente virtual de ensino, além de fornecer componentes (armazenamento, negócio e interface) para dar suporte à gestão de componentes multimídia (imagens, áudio e vídeo) e mundos de realidade virtual (VRML e X3D). Sua arquitetura permite a integração com plataformas de ensino a distância via troca de mensagens XML de forma que a plataforma de ensino possa usufruir de maneira transparente os serviços que o Servidor de Dados Multimídia provê. Para isso, foi feito um estudo sobre cada tipo de objeto multimídia e de realidade virtual e de como são armazenados tais objetos em banco de dados; foi elaborado e implementado um conjunto de protótipos, um para cada forma de armazenamento estudada, e foi feito um conjunto de avaliações baseadas em engenharia de desempenho de forma a definir a melhor abordagem para armazenar e recuperar estes objetos multimídia para ambientes de ensino a distância. Além disso, foi proposto um modelo de integração entre o servidor e plataformas de ensino a distância de forma que tais 4 plataformas possam usufruir dos serviços oferecidos de forma transparente. O servidor proposto nessa pesquisa faz parte de um projeto de pesquisa intitulado Projeto Amadeus_MM1, cujo objetivo é desenvolver um ambiente virtual para ensino baseado em uma proposta pedagógica centrada em processos de medição e avaliação, coordenado pelos professores Fernando Fonseca e Alex Sandro Gomes (Cin/UFPE).

In this context, we present a scheme to get around these limitations, based on use of local servers and a synchronization technique that enables mediation of access to central servers, keeping local resources even when Internet connection is interrupted, performing updates when the connection is reestablished again. The proposed scheme has been developed and tested in order to evaluate its behavior in different scenarios, as well as the corresponding user perception. / Limitações do acesso à Internet, decorrentes de conexões intermitentes e de baixa qualidade, tem se tornado o principal obstáculo para o uso de Ambientes Virtuais de Ensino e Aprendizagem em localidades fora das capitais e grandes cidades, especialmente em regiões geograficamente desafiadoras como é o caso da Amazônia. Nesse contexto, é apresentado um esquema para contornar tais limitações, baseado no uso de servidores locais e de uma técnica de sincronismo que possibilita a intermediação do acesso a servidores centrais, mantendo recursos locais ainda que a conexão a Internet seja interrompida, realizando as atualizações quando tal conexão for restabelecida. O esquema proposto foi desenvolvido e testado de modo a avaliar seu comportamento em diferentes cenários, bem como a correspondente percepção do usuário.
