Obtaining adequate and precise anatomical information is mandatory to prevent vascular access–related complications in dialysis patients. For this purpose, we underwent Doppler ultrasound, vascular access angiogram, and plain computer-assisted tomography scan of the arm with vascular access. With the use of computer graphics software, the anatomical structure of the vascular access can be visualized three dimensionally which is shared among the staffs for precise and better recognition. Furthermore, created object is applicable for virtual reality and/or augmented reality presentation that provides useful means for education and practical procedures in the management of vascular access.

Virtual Reality techniques were used to develop an interactive application concerning the incremental launching construction of bridges, in the area of Civil Engineering. It was developed in order to facilitate understanding of the various phases involved in the construction. The visualization of the distinct physical steps of the construction is shown in the virtual application. The model makes it possible to view the physical evolution of the work, to follow the planned construction sequence and to visualize details of the form of every component of the work. It also supports the study of the type and method of operation of the equipment necessary for this construction activity. The application of visual simulation was designed to allow direct access to any stage of the constructive process in which it is based and may be viewed from any point within the virtual scene, thus facilitating their understanding. The access to the application can be established through a web page placed on the Internet. The model brings new perspectives in the training activity as a support to expose innovative methods or complex sequence construction.

The integration of Internet and Multimedia Computer Technology provides new opportunities for e-commerce such as B2B/B2C. Web3D is emerging from the development of Internet and virtual reality. In this paper, we will use the specialty engine Unity3D as a development platform and JSP as a tool, to achieve the Web display system of virtual theater model, provided with accurate data, strong performance, virtual exhibition, interactive application. The platform across time and space limitations achieves a visual, vivid, more convenient information exchange to meet the demand for high-speed and efficient e-commerce information age for artistic performance enterprise publicity and marketing.

Processing Mechanisms

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.

Neue Technik

Fragestellung: Die dieser Untersuchung zugrunde liegende Frage war, ob das angewandte Ausbildungskonzept geeignet war, um am Beispiel der Einführung der laparoskopischen Cholezystektomie eine neue Operationsmethode in einer universitären Ausbildungsklinik mit einer grossen Anzahl Chirurgen zu etablieren. Patienten und Methodik: Seit Einführung der ersten laparoskopischen Cholezystektomie wurden alle Cholezystektomien während zwei Jahren (Mai 1990 bis Mai 1992) prospektiv erfasst. Ein Ausbildungskonzept wurde gewählt, bei dem jeweils ein Operateur durch einen Tutor geschult wurde und so 15 konsekutive Eingriffe durchführte, um dann die Technik einem weiteren auszubildenden Chirurgen zu instruieren. Resultate: In zwei Jahren wurden 355 Patienten cholezystektomiert. 60% der Operationen wurden laparoskopisch durchgeführt oder begonnen. 40% der Operationen wurden offen durchgeführt. In den ersten zwei Jahren konnten 13 Operateure (durchschnittlich 16 Operationen / Operateur , range 1 - 60) in die neue Technik eingeführt werden. Es traten keine schweren Komplikationen, insbesondere keine Gallenwegsverletzungen in dieser Einführungsphase auf. Diskussion: In der Literatur wird dieses Vorgehen bei der Einführungsphase seit 1992 wiederholt vorgestellt, diskutiert und empfohlen. Zwischenzeitlich gibt es Richtlinien von Fachgesellschaften und nationalen Institutionen, welche die Ausbildung zur Ausführung neuer chirurgischer Techniken reglementieren. In den letzten Jahren verlagern sich die ersten Ausbildungsschritte in Richtung Trainingskurse an skill-stations und virtual reality Trainer. Schlussfolgerung: Das beschriebene Ausbildungskonzept bewährte sich in der Einführungsphase der laparoskopischen Cholezystektomie zu Beginn der 90er-Jahre.
