Ontologies are a fundamental concept of the Semantic Web envisioned by Tim Berners-Lee [1]. Together with explicit representation of the semantics of data for machine-accessibility such domain theories are the basis for intelligent next generation applications for the web and other areas of interest [2]. Their application for special aspects within the domain of e-learning is often proposed to support the increasing complexity ([3], [4], [5], [6]). So they can provide a better support for course generation or learning scenario description [7]. By the modeling of didactics-related expertise and their provision for the creators of courses many improvements like reuse, rapid development and of course increased learning performance become possible due to the separation from other aspects of e-learning platforms as already proposed in [8].

This paper presents a framework to describe the crossover domain of e-learning and agent technology. Furthermore it is used to classify existing work and possible starting points for the future development of agent techniques and technologies order to enhance the performance and the effectiveness of several aspects of elearning systems. Agents are not a new concept but their use in the field of e-learning constitutes a basis for consequential advances. [ABSTRACT FROM AUTHOR]

Isolated fractures of the capitate, though rare, are probably often missed entirely. As in scaphoid fractures, repeated radiographs, tomography, or bone scanning are necessary for the diagnosis. Reviewing the literature, we found that most capitate fractures reported were transverse or combined with other carpal injuries, including the scapho-capitate fracture syndrome. Our patient presented an isolated oblique intraarticular fracture of the capitate. An old fracture of the styloid process of the ulna was seen at the primary examination. This special type of capitate fracture has not been previously described. The fracture was missed on standard radiographs, but discovered by computed tomography (CT). The different types of fractures of the capitate and their treatment are discussed.
