It represents a community that emerges as a temporal integration of two or more different business and educational communities and organizational cultures (industrial, research, and educational). The concept of IntelLEO is going to be investigated in a 3-year R&D project accepted for funding within the EU Seventh Framework Programme (FP7) and starting in early 2009. The project involves 8 partner institutions from Europe (both university/research and industry) and one from Canada. This paper presents the innovative concept of IntelLEO from the business case, technical, and pedagogical perspectives.

The central part of the framework is the LO Context ontology, that bridges a learning content ontology and a LD ontology. The LO context ontology is aimed at capturing information about the actual usage of a LO inside a LD, such as the learning activity the LO was used in, the pedagogical role assumed by the LO (e.g. exercise), the learner's features (represented in the form of the learner model) and the like. Furthermore we suggest the architecture of an adaptive educational system that leverages the proposed approach to enable personalization and reuse of LOs and LDs.

However, there are two important challenges to be addressed: i) combination of individual and organizational incentives that motivate employees to take part in knowledge building and sharing activities; and ii) structuring of learning and knowledge building activities and their outcomes in a representation that can assure unambiguous knowledge sharing.

We suggest that the social context plays an important role when it comes to defining learning goals, adapting one's strategies to social norms, and collaboratively creating knowledge with colleagues and peers. A first assessment of this motivational approach and early prototypes was conducted within the IntelLEO project by ...

The core of the proposed framework is a learning object context ontology that leverages a range of other kinds of learning ontologies (e.g. domain, user modeling, learning design etc.) to capture the context-specific metadata. On top of that framework, we develop the architecture of an adaptive educational system, in order to illustrate the benefits of our proposal for personalization of learning design. Finally, we reflect on how two present educational tools (iHelp Courses and TANGRAM) correspond to the proposed architecture.

Learning context related data represented in such a manner provides a solid ground for personalization of both LOs and LDs. The core part of the proposed framework is a LO Context ontology, that leverages a range of other kinds of learning ontologies (e.g. user modeling ontology, domain ontology, LD ontology etc.) to capture the information about the real usage of a LO inside a LD. Additionally, we present the architecture of an adaptive educational system based on the suggested framework, in order to illustrate the benefits of our proposal for personalization of LD.

An equally important research challenge for successful completion of each step of a self-regulatory process is to enable learners to be aware of characteristics of their organizationallyembedded learning context. In this paper, we describe how a combination of pedagogy and Semantic Web-based technologies can be utilized to address the above two challenges. Specifically, we demonstrate the proposed solution through the Learning Pal tool which leverages ontologies to support self-regulation in organizational learning.

This paper outlines a broad research agenda to mitigate these issues.. The first part of this approach is to collect prescriptive metadata from various actors involved using a light weight collaborative tagging approach. This is then augmented with content analysis done directly on learning objects to create concept and summarization metadata. Finally, interaction metadata observed from the environment in which the learning objects ...

The first tool, the Alfresco system, is a version controlled content repository designed in REST architectural style and based on a set of document management and collaboration services. The Alfresco workflow engine enables organization and automation of the process activities. The second tool, the Semantic MediaWiki portal, is a semantic collaboration tool and knowledge management system that leverages the latest Semantic Web (SW) technologies and standards. By using semantic annotations, it enriches the Web contents with semantics and makes the knowledge explicit. Thus, it provides structured access to information and accurate and precise knowledge retrieval. This paper discusses the customization of these tools and their utilization in the Web Technologies for West Balkan countries (Web4WeB) project.

The possibility of applying both the Fick's kinetics model and kinetics model of the first order chemical reaction to the swelling kinetics of the PAA hydrogel in distilled water and physiological solution were examined. It was found that the possibilities of applying these models were limited. The new model of the kinetics of swelling in distilled water and physiological solution was established. The kinetic parameters (E a , ln A) for the swelling in distilled water and physiological solution were determined. The decrease of the equilibrium degree of swelling and the saturation swelling rate of the swelling of the PAA hydrogel in physiological solution compared to swelling in distilled water could be explained by the decreased differences in the ionic osmotic pressures between the hydrogel and the swelling medium. The increase of the initial swelling rate in the physiological solution might be caused by an increased density of charges at the network and by an increased affinity of the network towards the water molecules. The increase of the activation energy of the swelling of the PAA hydrogel in the physiological solution is a consequence of its additional "ionic crosslinking".

Isothermal conversions and kinetic curves of Cu 2+ binding to the PAA hydrogel were determined. It was found that the well-known kinetic models of Peppas cannot be applied to describing the entire process of Cu 2+ binding. The new method for the determination of the kinetic model of the Cu 2+ binding process, as well as the activation energy density distribution functions of PAA hydrogel interaction with Cu 2+ , were established. It was found that Cu 2+ diffusion to the active centers (with E a = 9 kJ/mol) has a dominant influence on the kinetics of the process at temperatures T ≥ 30° C, but at T ≥ 30° C and for the degree of bound Cu 2+ α ≥ 0.2 , the interaction of Cu 2+ from the adsorption center with E a = 26 kJ/mol is dominant.
