Collapse Button Quick Abstract
Cortical stimulation is being investigated as a possible tool to support stroke rehabilitation. In particular the analysis of stimulation-evoked neural activity during the rehabilitation process might be helpful to gain a better understanding of the brain reorganization associated with functional recovery after stroke. In this paper, the stimulation-evoked brain activity from a patient with implanted epidural electrodes undergoing an intervention using of brain-computer interfaces combined with cortical stimulation for stroke rehabilitation has been analyzed. We identified a component of the evoked cortical activity that exhibited several characteristics that have not been described before: A significant latency decrease over the course of the rehabilitation training, a significantly smaller latency if the patient attempted to move his paralyzed hand compared to rest and a significant correlation of the latency with the spectral power of the ECoG signal. In addition to the latency, other parameters such as the peak amplitude of the evoked activity were tested as well, but showed a smaller effect size. We hypothesize that such “dynamic” components of the evoked activity that appear to be correlated with the rehabilitation process and the ongoing brain signal could be a target for future closed-loop stimulation systems.

Collapse Button Quick Abstract
In Germany more than 17,000 people die per year because of ”medical errors”, in the USA it is about 98,000. The number of avoidable malpractice cases or major complications is about tenfold higher. Nearly everyone will be a patient in a hospital sooner or later. A key concept to improve patient safety are modern, anonymous adverse event reporting systems in hospitals. These are known as incident reporting systems. The introduction of modern process-oriented technologies optimizes the efficiency of such systems and increases patient safety. IT saves lives, if it is possible to improve the analysis of medical incidents and to accelerate the detection of the underlying causes by optimizing the IRS processes. In this paper we present a generic process-oriented architecture and its application for incident reporting systems in health care organizations. Further, we formulate lessons learned concerning business process modeling and implementation for process-oriented architectures.

Collapse Button Quick Abstract
In recent years web applications have evolved from pure data-centric towards complex process-based applications that involve multiple users, organizations and systems. Web applications in the area of healthcare have been particularly affected by this evolution. New process-oriented technologies like business process management systems were used for the development of such web applications. They facilitate the implementation of the processes by providing tools for the process design, execution, administration and integration and guarantee performance and scalability. However, most web applications are implemented conventionally and therefore, cannot take advantage from these new technologies. What they are lacking is a methodology for converting conventionally implemented, intrinsically process-oriented web applications to process-oriented platforms. In the following article, a methodology is introduced that shows how web applications may be re-engineered towards process-oriented platforms. Furthermore, the relevance of this methodology to solve the challenges arising in a concrete web application in the area of healthcare, specifically incident reporting in hospitals, is outlined.
