Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of these traditional approaches. In this paper, the authors propose an alternative approach, i.e. process oriented ergonomics, which might be a constructive way of tackling some of the more complex aspects of the man-machine interaction in industrial environments such as assembly of engines.

Air traffic control is a highly spatial work. However, there are currently no three-dimensional tools used in the education of air traffic controllers or in the operational work of air traffic control. This paper presents results from some pilot studies aiming to: -Find new techniques for visualization and editing of trajectories in air traffic control. -Investigate how Virtual Reality (VR) can contribute to the air traffic controllers’ understanding of the air space and of certain situations. Two VR models have been developed. In one model a procedure called ‘holding’ is visualized. In the other VR model the different sectors in the air space are shown to make it easier for the air traffic controller to build a mental picture of a sector. In a training package the user can fly around in the sector and see how traffic passes through. These introductory studies indicate the usefulness of new ways to present the third dimension in a variety of air traffic situations. The tools can be used to visualize a three dimensional situation and help the air traffic controller to build a mental model The most obvious application area is in training and education of air traffic controllers but other applications such as an explanation and communication tool in the investigation after an incident are of interest.

A project focusing on identifying and describing maritime risks is being conducted in the heavily trafficked water area of the Sound, situated in northern Europe between Sweden and Denmark. This paper reports of a test of a first version of a questionnaire constructed for measuring safety culture onboard vessels.48 crew members on a Swedish registered passenger/cargo ship completed and returned the questionnaire. The crew members were able to complete the questionnaire with few unanswered questions. Acceptable homogeneity was obtained for all but one of the nine dimensions of safety culture. Significant differences on several of the safety culture dimensions were found between deck/engine vs catering personnel, men vs women and different age groups, while little differences were found for supervisors vs non-supervisors or people with varying number of years onboard. Such safety culture dimensions need to be studied in relation to reports of accidents and near-misses, to further study the true relevance of safety culture.
