The research approach is based on the Technology Acceptance Model (TAM). More specifically, the model is devoted to identifying barriers and enablers to the acceptance of these technologies. A questionnaire comprising three factors (Attitude toward using technology, Perceived ease of use and Perceived usefulness) was applied to a sample consisting of 121 higher education students. Results show that the perceived ease of use of cloud file hosting services is above that of LMS tools and services and that cloud file hosting services presented higher levels of perceived usefulness than standard learning management tools. In addition, attitude toward using cloud file hosting services is well above that of using LMS tools.}, language = {en} } @inproceedings{GhulamSchubertTammetal.2014, author = {Ghulam, Sarfaraz and Schubert, Johannes and Tamm, Gerrit and Stantchev, Vladimir}, title = {Integrating Smart Items and Cloud Computing in Healthcare Scenarios}, pages = {7}, year = {2014}, abstract = {Use of cloud computing in healthcare is a promising trend, particularly in utilization of smart items. Access, affordability and quality to proper healthcare is a great challenge in world society. With the utilization of smart sensors, there are possibilities to improve the quality of healthcare services whenever needed. Hence, such smart items services lead to economic advantages for the whole healthcare system. Keeping in mind these opportunities as well as challenges such as security or legal issues, it is important to bring healthcare and IT together. As a result, healthcare business processes need to be modeled in order to provide IT solutions tailored for practice-oriented applications. In this paper, we present a three-level architecture for a smart healthcare infrastructure. Our approach is based on recent literature work and results from conducted expert interviews with healthcare specialists and IT professionals. To demonstrate the applicability of this architecture model, we provide an example use-case as a template for any kind of smart sensor-based healthcare infrastructure.}, language = {en} } @article{SchermulyDraheimFlessaetal.2014, author = {Schermuly, Carsten C. and Draheim, Michael and Flessa, Steffen and Glasberg, Ronald and Stantchev, Vladimir and Tamm, Gerrit and Hartmann, Michael and Hessel, Franz}, title = {Management of Crises and Risks in German Hospitals: Factors Influencing Medication Errors}, series = {Value in Health}, volume = {17}, journal = {Value in Health}, number = {7}, pages = {A426}, year = {2014}, abstract = {In German hospitals there is a need for optimized crisis- and risk management.

Design/methodology/approach - This is exemplified by an application scenario in healthcare that was developed in the context of the OpSIT project in Germany. A clearly outlined three-layer architecture, in the sense of Internet of Things, is presented. It provides the basis for integrating a broad range of sensors into smart healthcare infrastructure. More specifically, by making use of short-range communication sensors (sensing layer), gateways which implement data transmission and low-level computation (fog layer) and cloud computing for processing the data (application layer). Findings - A technical in-depth analysis of the first two layers of the infrastructure is given to provereliability and to determine the communication quality and availability in real-world scenarios. Furthermore, two example use-cases that directly apply to a healthcare environment are examined,concluding with the feasibility of the presented approach. Practical implications - Finally, the next research steps, oriented towards the semantic tagging and classification of data received from sensors, and the usage of advanced artificial intelligence-based algorithms on this information to produce useful knowledge, are described together with the derived social benefits. Originality/value - The work presents an innovative, extensible and scalable system, proven to be useful in healthcare environments.}, language = {en} }
