A Noble Structural Model for e-Learning Services in Ubiquitous Environment

As e-learning studying is activated, learners' requirements are increased. It is important to note that the effective e-learning model augmented requirements of learner and new ubiquitous environment are artifacts of an era of u-learning. This paper has analyzed learners' requirements and limitations in the existing e-learning system, and proposed the addition of contents conversion service and collaborative learning service to LMS based on SCORM standard proposal using ubiquitous network, next-generation sensor technology, etc. in order to construct effective and unbounded u-learning system in ubiquitous environment. Based on this structural model. we also propose XML-MCAS security method suitable for wireless environment for preventing the leakage of personal and contents information.
