INTRODUCTION Safety culture is considered as an important factor in improving patient safety. Therefore, identifying individual and organizational factors affecting safety culture is crucial. This study was carried out to determine individual and organizational factors associated with nurses' perception of patient safety culture. METHODS The present descriptive study included 940 nurses worki...

In this paper selected aspects of human factors are discussed that should be taken into account during the design of safety-related functions for a complex hazardous installation and its protections. The layer of protection analysis (LOPA) methodology is used for simplified risk analysis based on defined accident scenarios. To control the risk the safety instrumented functions (SIFs) are identi...

The generic software development situational factors model has been developed in order that environments within which software is developed can be profiled and better understood. Situational context is a complex concern for software developers, with a broad set of situational factors holding the potential to affect any one software development project. Safety critical software development is br...

A human factors model is used to highlight the nature of many systems factors that affect surgical performance, including the OR environment, teamwork and communication, technology and equipment, tasks and workload factors, and organizational variables. If further improvements in the success rate and reliability of cardiac surgery are to be realized, interventions need to be developed to reduce...

A factor of safety method for quantitative estimates of grid-spacing and time-step uncertainties for solution verification is developed. It removes the two deficiencies of the grid convergence index and correction factor methods, namely, unreasonably small uncertainty when the estimated order of accuracy using the Richardson extrapolation method is greater than the theoretical order of accuracy...

This paper presents the safety case for the consideration of cross-cultural factors in aviation by focusing on cultural interfaces, those situations where members of one culture encounter people or artifacts from other cultures. Global aviation is strongly influenced by the USA and Western Europe as the largest manufacturers and largest customers; hence almost all cultural interfaces are weight...

The main objective of this thesis is to investigate how selected standards are applied within an industrial context and to suggest strategies to improve their application. This thesis focuses on the human part of large and complex systems. Humans are essential in any large and complex system, but their complexity makes it virtually impossible to fully predict their behaviour and impact on such ...

Of course, from childhood to forever, we are always thought to love reading. It is not only reading the lesson book but also reading everything good is the choice of getting new inspirations.

The European Commission estimates that car crash-related costs in Europe are around 160 billion euros, approximately 2% of the Gross Domestic Product [1]. In several countries, car crashes are the first cause of death among subjects aged 15-30, with a direct heavy impact on the years of life lost; in young subjects car crashes also represent one of the major causes of disability [2]. Several dr...
