Abstract. The development of teaching materials has currently became one of the main concerns of the specialists from various domains, including medicine. The continuous development of e-Learning applications demands the creation of new types of resources that encourage individual study activities with automatic system monitoring and less involvement from the teacher. One of the most promising approaches used currently for creating this type of educational materials in an efficient manner is the improvement and repurposing of the already existing resources. Nevertheless, this method generates new issues related with the description of the connections between the involved resources and also with the search process and identification of the relevant, good quality materials. In this paper we present a possible solution to these problems based on the characteristics of the social networks blended with functionalities specific to the semantic web. Through these tools we will describe the relations between resources and will consequently be able to provide more significant search results. The application presented, called Metamorphosis+, exposes a user interface that hides the complexity of the description process and allows users without technical background to benefit from the provided functionalities.

Keywords: semantic web, social network, Web 2.0, repurposing of teaching materials.

Abstract. This paper describes and applies various methods for automatic computer music segmentation. Based on these results and on the feature extraction techniques used, is tried also a genre classification/recognition of the excerpts used. The algorithms were tested on the Magnatune and MARSYAS datasets, but the implemented software tools can also be used on a variety of sources. The tools described here will be subject to a framework/software system called ADAMS (Advanced Dynamic Analysis of Music Software) that will help evaluate and enhance the various music analysis/composition tasks. This system is based on the MARSYAS open source software framework and contains a module similar to WEKA for data-mining and machine learning tasks.

Keywords: automatic segmentation, audio classification, music information retrieval, music content analysis, chord detection, vocal and instrumental regions.

Abstract. The graphical user’s interfaces accessibility is a key condition for visual disabled peoples to use the computer applications. This paper presents the MOM (Meaningful Object Manager) software tool for accessibility analysis of graphical user interfaces. The accessibility depends not only on the tested applications, but also on assistive technologies. During this paper the functionalities of the MOM tools are described as well as the way these are used for accessibility evaluation. For each component are presented several case studies.

Keywords: accessibly, assistive technology, visual impairment.

Abstract. Although the web accessibility problem was given a high visibility at European level, the progress is still unsatisfactory. In this paper we present the results of a study carried on in 2012. The purpose of the study was to assess the conformance against WCAG 2.0 accessibility guidelines of 98 web sites from the local public administration. For each web site three web pages were evaluated. The results are comparatively analysed with those of a previous study from 2011, targeting a sample of 30 municipal websites. The results show a low level of web accessibility.

Keywords: accessibility, WCAG 2.0, conformance evaluation.

Abstract: Recent studies focuses on topical issues related to Facebook, its use and impact on billions of young people´s social life who may accessing this website on a daily basis. User public profiles, as well as the content they distributed throughout the network can provide teachers and counsellors with a variety of socio-demographic information, along with information on skills, preferences, hobbies, and personality traits. Therefore, this paper critical examines the results of studies examining the online behaviour of users, particularly students, in order to analyse how certain personality traits may influence their preferences in using Facebook, as well as the relevance of such findings for the educational practice.

Keywords: Facebook, social network, behavior, personality, identity.

Abstract: In this paper are presented the evaluation result of an augmented reality platform for teaching chemistry based on a methodology which combines the think aloud protocol – TAP and peer-tutoring method. During TAP, the student’s task was to think aloud while solving the exercises from chemistry scenario. The students where asked to describe all they think, do and feel during the exercises. Peer tutoring supposed that students who tested the application based on TAP, teach other students to use it. We consider that this approach supports a better communication during testing then the communication of students with an adult and also offer more information about the potential of the application to be learned.

Keywords: evaluation, augmented reality, TAP, peer tutoring.
