Research for sustainable development: Foundations, experiences, and perspectives

Research for Sustainable Development is based on the experiences of a decade of inter- and transdisciplinary research in partnership in nine regions of the world. It presents 29 articles in which interdisciplinary teams reflect on the foundations of sustainability-oriented research, propose and illustrate concrete concepts, tools, and approaches to overcome the challenges of such research, and show how research practice related to specific issues of sustainable development has led to new thematic and methodological insights. The book seeks to stimulate the advancement of research towards more relevant, scientifically sound, and concrete contributions to realising the vision of sustainable development.

The foundations of computer assisted surgery

Using navigation systems in general orthopaedic surgery and, in particular, knee replacement is becoming more and more accepted. This paper describes the basic technological concepts of modern computer assisted surgical systems. It explains the variation in currently available systems and outlines research activities that will potentially influence future products. In general, each navigation system is defined by three components: (1) the therapeutic object is the anatomical structure that is operated on using the navigation system, (2) the virtual object represents an image of the therapeutic object, with radiological images or computer generated models potentially being used, and (3) last but not least, the navigator acquires the spatial position and orientation of instruments and anatomy thus providing the necessary data to replay surgical action in real-time on the navigation system's screen.
