With the development of science and technology, occupational accidents, as one of the most important problems in the world, result in negative effects on physical and psychological health, and also the quality of life of workers. The aim of this study was to compare the quality of life among workers with and without accident. In a cross-sectional study, 93 workers were selected, 31 who experien...

Traffic accident data are often heterogeneous, which can cause certain relationships to remain hidden. Therefore, traffic accident analysis is often performed on a small subset of traffic accidents or several models are built for various traffic accident types. In this paper, we examine the effectiveness of a clustering technique, i.e. latent class clustering, for identifying homogenous traffic...

In order to address the difficulty of arranging large calibration objects and the low measurement accuracy of small calibration objects in traffic accident scene photogrammetry, a photogrammetric method based on a composite of small calibration objects is proposed. Several small calibration objects are placed around the traffic accident scene, and the coordinate system of the composite calibrat...

This paper deals with the processing of accident scenarios generated from a dynamic reliability analysis of a Nuclear Power Plant (NPP). A large number of scenarios are simulated to account for the influence of the timing and magnitudes of fault events on the accident end states; post-simulation processing is then required for retrieving the safety-relevant information. For classifying the fina...

This study aimed to investigate the correlation of different impact conditions to the injury severity and impact biomechanics of pedestrians in real world accidents, and study the tolerance level with focus on head-brain of adults and children via indepth analysis and reconstructions of real world accidents. For this purpose, 188 pedestrian accident cases were selected from existing accident da...

A model or set of assumptions about how accidents occur lies at the foundation of all accident prevention and investigation efforts. Traditionally, accidents have been viewed as resulting from a chain of events, each directly related to its “causal” event or events. The event(s) at the beginning of the chain is labelled the root cause. Event-chain models, however, are limited in their ability t...

The article presents a case of successful surgical treatment pulmonary embolism in patient with high risk early cardiac death on the background paradoxical complicated by acute cerebrovascular accident. Cryptogenic accident combination severe progressive right ventricular failure causes serious difficulties making decisions regarding tactics these patients. Intracardiac localization thromboembo...

Accident models play a critical role in accident investigation and analysis. Most traditional models are based on an underlying chain of events. These models, however, have serious limitations when used for complex, socio-technical systems. Previously, Leveson proposed a new accident model (STAMP) based on system theory where the basic concept is not an event but a constraint. This paper shows ...
