Driving after cerebral damage: a model with implications for evaluation.

Evaluation of the ability of cerebrally injured patients to return to driving is an important task for rehabilitation specialists. These evaluations require predictively valid methods of assessment based on identification of relevant skills and abilities. The present study tested a hypothetical model for driving after cerebral injury and determined its use in evaluating fitness to drive. Thirty-five patients with cerebral damage due to head injury or cerebrovascular accident participated in the study. All were administered (a) a predriver evaluation, that is, a battery of neuropsychological tests chosen a priori to test the model, (b) a simulator evaluation, and (c) a behind-the-wheel evaluation consisting of driving on a protected course and in traffic. The results showed that 93% of the driving outcome in traffic was explained cumulatively by findings from the predriver and simulator evaluations as well as from behavioral and operational measures during evaluation on the protected lot. These results supported the predictive validity of the model and are discussed in terms of methodology for evaluation of return to driving.

Complex task performance in Cyberspace. Surgical procedures in a telepresence environment.

To assess the capabilities of our fully functional, prototype telepresence surgery system, experienced surgeons performed complete operative procedures on live, anesthetized pigs. Cholecystectomy, the prototypical procedure for evaluating the integration of surgical skills, was successfully performed in six animals. There were no aborted attempts or complications. Other procedures completed included gastrotomy and enterotomy closures, anastomosis of the small intestine, and nephrectomy. No specific training was required for using the telepresence surgery system, and the "feel" of the system was described as intuitive. Operative times were longer than required in conventional, open surgery, most likely the result of the four degrees of freedom available in the manipulators of the current-generation system. Force feedback and high-resolution, stereoscopic video input facilitated performance. Surgeons operating through a first-generation telepresence system can achieve technical results equivalent to those obtained in conventional surgery.

Human body textbook with three-dimensional illustrations.

We made a toolkit for making education softwares using 3D computer graphics, and using the toolkit, we made an education software based on 3D illustrations for learning about the human body. The toolkit enables us to make such kind of education software based on 3D illustrations easy and systematic. In the education software, the human body structure is illustrated with 3D models. The user can see the 3D objects with real-time rotation and walk through the virtual space, and their functions are expressed in the 3D virtual space.

[The protective signalization of human vital functions: methodology, concept, devices].

The paper describes a basically new approach to solving the most pressing sociomedical approach, i.e. timely rendering a medical aid when acute vital dysfunctions suddenly occur in real daily life. A new concept of medical instrument making for human life and health protection has been developed on the basis of the theory of functional systems which discloses the universal mechanisms of self-regulation of the body's function. Its practical application is the design and patent a number of original devices of the protective signalling system which may be classified as information microprocessor devices designed for daily individual continuous control and notification of the first objective signs of physiological dysfunctions.
