Diversity inside a group of users having their individual abilities, interests, and needs challenge the developers of eHealth projects with heterogeneous needs in information delivery and/or other eHealth services. This paper considers an adaptive user interface approach as an opportunity in addressing this challenge. We briefly overview the recent(More)
Traditional data mining techniques have been extensively applied to find interesting patterns, build descriptive and predictive models from large volumes of data accumulated through the use of different information systems. The results of data mining can be used for getting a better understanding of the underlying educational processes, for generating(More)
A number of recent studies have contributed to Knowledge Management (KM) and E-learning integration. They are mainly based on organizational learning analysis. In this paper, KM is discussed from the viewpoint of adaptation in e-learning systems. The main components of adaptive e-learning system are discussed with respect to the KM processes. We analyze(More)
AIM A recently discovered enzyme, indoleamine 2,3-dioxygenase (IDO), is expressed in placenta, dendritic cells and also in many kinds of tumors and in tumor-infiltrating macrophages. By catabolizing tryptophan, IDO causes local depletion of this essential amino acid and excess of kinurenin, and suppresses in situ proliferation and functioning of T(More)
Design of feedback is a critical issue of online assessment development within Web-based Learning Systems (WBLSs). This paper examines the potential possibilities of tailoring the feedback that is presented to a student as a result of his/her preferences and responses to questions of an online test with respect to the individual learning styles (LS). The(More)
In this paper we describe an educational data mining (EDM) case study based on the data collected during the online assessment of students who were able to immediately receive tailored and elaborated feedback (EF) after answering each of the questions in the test. Our main interest as domain experts (i.e. educators) is in studying (by employing any kind of(More)
Design of feedback is a critical issue of online assessment development within Web-based Learning Systems (WBLSs). In our work we demonstrate the possibilities of tailoring the feedback to the students’ learning style (LS), certitude in response and its correctness. We observe in the experimental studies that these factors have a significant influence on(More)
Remote patient management (RPM) systems enable (i) monitoring of vital signs of patients at their home, and (ii) providing patients in their homes instructional, educational, or motivational feedback. As such, RPM systems collect a lot of (different types of) data about patients. Although richness of data provides an opportunity for tailoring and(More)
Feedback is information that is provided to a user to inform him/her about the result of his/her action and to motivate him/her to further interact with the system. In web-based learning systems (WBLS), feedback is particularly important in test and evaluation tasks. The main objective of the paper is twofold: (1) to encourage WBLS designers and specialists(More)
