Recent studies have shown that unsafe driver acts can be classified into two distinct categories (i.e.. errors and violations) entailing different measures for reducing road traffic accidents. A survey of over 1,400 drivers in Greece is reported in which a variety of aberrant driving behaviours have been identified. The present study has confirmed the(More)
This paper investigates workarounds occurring while pharmacists use an electronic prescription (ePrescription) application. ePrescription enables physicians to send prescriptions electronically to pharmacies and was recently introduced in Greece as a solution for controlling the ever-increasing medication costs and improving patient safety. The research was(More)
In this paper we present the way we modelled and simulated a metro system in the case of a tunnel fire, and discuss the ways this simulation may support the search for efficient rescue plans. The metro system was modelled as a complex adaptive system, comprising four interacting and co-evolving subsystems: (i) the fire and the released smoke, (ii) the group(More)
This paper proposes a method and an information technology tool aiming to support the ergonomics layout design of individual workstations in a given space (building). The proposed method shares common ideas with previous generic methods for office layout. However, it goes a step forward and focuses on the cognitive tasks which have to be carried out by the(More)
The aim of the present paper is to contribute to the debate in the cognitive ergonomics community as for the adequacy of different approaches for the analysis of socio-technical systems in view of designing artifacts facilitating human work. Using a taxonomy of sociotechnical systems as frame of reference, the theoretical origins and the main application(More)
The present paper deals with a teaching method aiming at overcoming the difficulties of students for conceptual or abstract thinking within a course of User Centred Design. Following the hermeneutic approach a series of small in class exercises have been planned. In those exercises students are urged to brainstorm from early on with all levels of solution(More)
In the present paper we argue that the effectiveness of interventions/design solutions supporting emergency evacuation of crowds in socio-technical systems, depends on the appropriateness of the models used for the crowd behaviour. After reviewing basic approaches already used to model escaping crowds, the knowledge about crowd behaviour provided by modern(More)
