Intriguing phenomena occur when experts use computer-assisted design tools in electronics. It can be seen that tools must support information access, 'escape from formalism', 'secondary notation', and differences between individual users. This paper explores a new account for the data, relying on the idea of graphical implicature, generalised from Grice's conversational implicature. All communicative artefacts carry implicatures, significance beyond their literal meaning. The important thing is to control them systematically, so that a graphic avoids unwanted implicatures, and carries the desired ones. Whether or not the current account is useful has broader significance. If it is useful, it may prove possible to predict and explain the properties of complex graphical representations, by borrowing formal techniques from natural language pragmatics.

The purpose of this report is to review the ethical and legal issues regarding the integration and application of computer technologies into the schools, particularly when used by speech-language pathologists and audiologists. Four broad issues are addressed: (a) software copyright and licensed use, (b) information access and the right to privacy, (c) computer-assisted or computer-administrated assessment and intervention, and (d) documentation. When using computer technologies, the practicing clinician should focus on clinical competencies and professional responsibilities in order to avoid the ethical pitfalls and legal traps associated with the integration of these technologies into schools. This is best achieved when the clinician has a current and broad knowledge domain, displays sound clinical judgment, and demonstrates competent clinical skills when applying computer technologies.

The integration of surgical knowledge into virtual planning systems plays a key role in computer-assisted surgery. The knowledge is often implicitly contained in the implemented algorithms. However, a strict separation would be desirable for reasons of maintainability, reusability and readability. Along with the Department of Oral and Maxillofacial Surgery at Heidelberg University Hospital, we are working on the development of a virtual planning system for mandibular reconstruction. In this work we describe a process for the structured acquisition and representation of surgical knowledge for mandibular reconstruction. Based on the acquired knowledge, an RDF(S) ontology was created. The ontology is connected to the virtual planning system via a SPARQL interface. The described process of knowledge acquisition can be transferred to other surgical use cases. Furthermore, the developed ontology is characterised by a reusable and easily expandable data model.
