In the last decades, the technological and scientific evolution of the computing discipline has been widely affecting research in software engineering education, which nowadays advocates more enlightened and liberal ideas. This article reviews cross-disciplinary research on a computer architecture class in consideration of its switching to microcomputer architecture. The authors present their strategies towards a successful crossing of boundaries between engineering disciplines. This communication aims at providing a different aspect on professional courses that are, nowadays, addressed at the expense of traditional courses.  相似文献   

Network-Based Business Simulation Activities in Technical Professional Education     

Vassilios C. Vescoukis  Symeon Retalis  Dimosthenis Anagnostopoulos 《Interactive Learning Environments》2013,21(3):169-191

For a long time on-the-job training has been considered as the single point of contact of technical education with the real world job market. Indeed, traditional on-the-job training activities are of great educational value and complement uniquely any classroom-based learning activity. However, it has been observed that several obstacles arise when integrating on-the-job training with traditional learning and that new network-based tools can be used to improve the situation. Following this concept, in this paper we introduce a network-assisted educational structure for business simulation activities which can be considered as an alternative or a complement to on-the-job training activities in technical professional education. Business Simulation Activities are based on the execution of business scenarios in a controlled educational environment with support by network tools. A simulation of the real world business environment is created and virtual companies are established in order to participate in a virtual marketplace using network-based learning support and aiming to provide on-the-job experience without the shortcomings of traditional on-the-job training. An operational structure, network distribution, implementation issues, as well as some experience from a pilot implementation of the concept, are presented in this paper.  相似文献

One of the most significant challenges implementing colloidal magnetic nanoparticles in medicine is the efficient heating of microliter quantities by applying a low frequency alternating magnetic field. The ultimate goal is to accomplish nonsurgically the treatment of millimeter size tumors. Here, we demonstrate the synthesis, characterization, and the in vitro as well as in vivo efficiency of a dextran coated maghemite (γ-Fe₂O₃) ferrofluid with an exceptional response to magnetic heating. The difference to previous synthetic attempts is the high charge of the dextran coating, which according to our study maintains the colloidal stability and good dispersion of the ferrofluid during the magnetic heating stage. Specifically, in vitro 2 μl of the ferrofluid gives an outstanding temperature rise of 33 °C within 10 min, while in vivo treatment, by infusing 150 μl of the ferrofluid in animal model (rat) glioma tumors, causes an impressive cancer tissue dissolution.  相似文献
