include a workshop and a seminar held in the English language. For the seminar, the graduate computer science students have to provide both, a Powerpoint presentation of their chosen topic and a paper, written in the style of a technical conference contribution. This technical report features the results of the first two seminars held in the summer semester 2004 and the winter semester 2004/2005. Each contributed paper was peer-reviewed by at least two seminar participants and was modified by the authors prior to publication in this report according to the hints of the reviewers and the seminar chair. To allow for a wide range of topics and to motivate students from software engineering, technical and business-oriented areas of computer science, the following title was chosen: Contemporary Challenges in Information Technology. The selected topics cover theoretical and/or practical aspects of relevant research fields. For the participants of the seminars it was the goal to improve their awareness for interdisciplinary and systems-oriented thinking. It should allow them to integrate their specific personal backgrounds and improve their ability to follow interdisciplinary discussions with their peers both during their studies and their professional careers
