BACKGROUND: Preparing medical students for the takeover or the start-up of a medical practice is an important challenge in Germany today. Therefore, this paper presents a computer-aided serious game (eMedOffice) developed and currently in use at the RWTH Aachen University Medical School. The game is part of the attempt to teach medical students the organizational and conceptual basics of the medical practice of a general practitioner in a problem-based learning environment. This paper introduces methods and concepts used to develop the serious game and describes the results of an evaluation of the game’s application in curricular courses at the Medical School. RESULTS: Results of the conducted evaluation gave evidence of a positive learning effect of the serious game. Educational supervisors observed strong collaboration among the players inspired by the competitive gaming aspects. In addition, an increase in willingness to learn and the exploration of new self-invented ideas were observed and valuable proposals for further prospective enhancements were elicited. A statistical analysis of the results of an evaluation provided a clear indication of the positive learning effect of the game. A usability questionnaire survey revealed a very good overall score of 4.07 (5=best, 1=worst). CONCLUSIONS: We consider web-based, collaborative serious games to be a promising means of improving medical education. The insights gained by the implementation of eMedOffice will promote the future development of more effective serious games for integration into curricular courses of the RWTH Aachen University Medical School.

Increasing traffic loads and changes in code provisions lead to deficits in shear and flexural capacity of many existing highway bridges. Therefore, a large number of structures are expected to require refurbishment and strengthening in the future. This projection is based on the current condition of many older road bridges. Different strengthening methods for bridges exist to extend their service life, all having specific advantages and disadvantages. By applying a thin layer of carbon textile-reinforced mortar (CTRM) to bridge deck slabs and the webs of pre-stressed concrete bridges, the fatigue and ultimate strength of these members can be increased significantly. The CTRM layer is a combination of a corrosion resistant carbon fiber reinforced polymer (CFRP) fabric and an efficient mortar. In this paper, the strengthening method and the experimental results obtained at RWTH Aachen University are presented.

Background: Due to prevailing future challenges in vocational rehabilitation, development process RehaFutur (BMAS) was initiated. In this context, recommendations were made to secure a future-oriented, innovative vocational rehabilitation in Germany. Deutsche Rentenversicherung (DRV) Westfalen transferred these recommendations into a new and applicable counseling concept RehaFutuReal(®). Rehabilitation managers (RM) are central protagonists in counseling process. Therefore, RehaFuturReal(®) focused on optimization of counseling performance. To achieve this aim, rehabilitation managers were taught to work with a case management (CM) based approach. RWTH Aachen supported RehaFuturReal(®) from an academic point of view and conducted a formative and summative evaluation. Primary aim of RWTH Aachen was to support DRV Westfalen during implementation of RehaFuturReal(®) into their organizational structure. Additionally, RWTH Aachen controlled whether transfer of RehaFutuReal(®) in counseling process was successful. Method: From 04-01-13 until 12-31-14, RehaFuturReal(®) was tested by DRV Westfalen in the intervention district Dortmund with 10 RM. There were 3 selection criteria for the overall sample of N=320 insurants: participants were required to have an active employment status, suffered from integration issues and were in need of support to achieve vocational integration. Evaluation of RehaFuturReal(®) was realized summative (pre-post-comparison) and formative (process-orientated). Evaluative judgment regarding implementation in organizational structure and counseling process was performed by using three-stage-concept of Donabedian (quality of structure, process and results). Thereby, feedback of RM, insurants and employers was taken into account. Results: Analysis of evaluation results revealed a positive overall impression. Implementation into organizational structure was successful on all 3 quality stages: concept of project and CM-training were an adequate basis and appropriately put into practice by fulfilling prescribed objectives, topics and schedule (quality of structure). Rehabilitation managers identified themselves with the implementation process into DRV Westfalen (grading of CM training: M=1,67; SD=0,65; quality of process). Analogous, consultants reported a high level of satisfaction during implementation of new counseling process (possible span: 1-4; M=3,11; SD=0,33; quality of results). Regarding implementation of counseling process, sample fitted into 3 selection criteria wherefore the correct insurants were picked in RehaFuturReal(®) (quality of structure). CM-orientated counseling approach was properly implemented into everyday work of RM by using CM-instruments for documentation (quality of process). RM were highly satisfied (possible span: 1-4) with counseling performance (M=3,43; SD=0,77). Employers also rated counseling performance positively (M=3,38; SD=0,85). By contrast, surveying insurants revealed a heterogeneous impression of satisfaction (M=2,97; SD=1,03) (quality of results).

A partnership between Brazil’s first undergraduate program in Acoustical Engineering and the Institute of Technical Acoustics of RWTH Aachen University yielded in a didactic project that uses the engineering software MATLAB with the ITA-Toolbox to teach acoustic measurements. Simple electrical circuits are used to mimic typical behavior of acoustical systems. This low-cost solution has proven to be didactically very effective since it helps students to identify themselves with the measurement tasks. Two hardware solutions were developed-a simple oscillator circuit integrated into connectors of audio cables and a desktop box containing seven different transfer characteristics ranging from ideal linear and time-invariant to nonlinear and time-varying behavior. Undergraduate students of Acoustical Engineering used both devices in classroom experiments for self-guided learning by comparing their results to published results. Students were able to learn the fundamental concepts of acoustical measurements and to handle measurement tasks. Besides the practical experiences and the learning effect, the students were also encouraged to step into the open source routines of the software, understand the signal processing steps, adapt routines, and even write their own ones, e.g., a GUI that provides effective control of the measurement via touch-screens.
