AbstractThe article presents problems related to the implementation of railway investments related to obtaining authorization for placing in service of structural subsystems. The main purpose of the investment is to increase speed on railway lines while keeping or improving the level of safety. All modernized railway lines are subject to the certification process. Any interference in the certified subsystem involves the need to assess the introduced change in accordance with the requirements of the common safety method for risk evaluation and assessment. Such assessment may also generate various interpretation problems, therefore it is necessary to assess the impact of implemented investments on already built-in devices of the control - command and signalling subsystem - trackside equipment.

There is a noticeable increase in rail freight shipment in recent years. European Union’s transport policy, infrastructure investments and opportunities given by the New Silk Road, point to new possibilities for development in this field of transport. Commission Implementing Regulation (EU) 402/2013 of 30 April 2013 on the common method for risk evaluation and assessment and repealing Regulation (EC) No 352/2009 distinguishes six stages of proceeding in risk assessment process. Key one among them, regarding this article, is risk assessment and classification. For the cargo to safely reach recipients, conditions allowing for continuous flow of fright needs to be provided. While realizing railway fright shipment, undesirable events can occur, that disrupt the shipment process. This events can be identified on the railway tracks, in the shipment, transhipment and destination points, caused by human actions or atmospheric conditions.

Abstract Objectives To test the ability of an established traditional cardiovascular (CV) risk prediction score [Systematic COronary Risk Evaluation (SCORE)] and its EULAR modified version (mSCORE) to identify antisynthetase syndrome (ASyS) patients at high CV risk and to examine for the first time associations of CV and cerebrovascular surrogate markers with clinical and immunological ASyS parameters. Methods SCORE/mSCORE and the gold standard marker of aortic stiffness [carotid-femoral pulse wave velocity (cfPWV)] were examined in ASyS patients and healthy controls. Moreover, sonography of the common- (CCA) and internal- (ICA) carotid arteries was performed in subsets of both groups, evaluating carotid intima-media thickness (cIMT), plaques and Doppler sonographic cerebrovascular surrogates [resistance (RI) and pulsatility (PI) indices]. Results We recruited 66 ASyS patients and 88 controls. According to mSCORE, 10% of the patients had high CV risk. However, cfPWV and carotid sonography revealed an increased CV risk in 21.2% and subclinical carotid atherosclerosis (SCA) in 85.7% of the patients, respectively. cfPWV and cIMT were higher in patients compared with controls (Padj=0.021 and Padj=0.003, respectively). In the ASyS group, cfPWV and cIMT correlated significantly with age (r = 0.679; P<0.001 and r = 0.664; P<0.001, respectively). Moreover, cfPWV correlated with BMI (Padj=0.001) and diabetes (Padj=0.043). CCA-RI and CCA-PI showed significant associations with creatine phosphokinase (r = 0.629; P=0.012 and r = 0.574; P=0.032, respectively) and ICA-RI and ICA-PI were higher in patients with lung involvement (both; P=0.039). Conclusion ASyS patients had higher aortic stiffness and SCA compared with controls, even after adjustment for confounders. SCORE/mSCORE performed poorly in identifying high-risk patients compared with cfPWV and carotid sonography. Thus, cfPWV and carotid sonography may improve CV and cerebrovascular screening in ASyS.

The approach to evaluation of health risks to aviation crew discussed in this paper is an alternative to the common clinical practice, i.e. stratification of the risks of diseases and complications which is sometimes underestimated by members of aircrew medical certification boards. The approach consists of ranking health issues by severity and impact on flight safety, and risk probability. The updated risk evaluation matrix was used successfully in cardiovascular diagnostics of aircrews. In aeromedicine, this approach is aimed at objective cardiovascular risk evaluation and prevention of accidents and serious incidents in consequence of problems with the cabin crew health.

Abstract In the light of the challenges of the Industry 4.0 the weight of safety and health, and ergonomics are rising. Nowadays one of the common problem in industry are work-related musculoskeletal disorders (WRMSDs). Therefore, an ergonomic risk evaluation is crucial as well the knowledge and education in this area. This paper presents a computerized tool for ergonomic education on ergonomic risk evaluation at the workplace. The tool based on quick exposure check pen and paper technique and Excel spreadsheet environment. It is easy to use and assists students in the evaluation of real as well of simulated workplaces. The proposed tool includes a few integrated parts: background description, students - observer’s and worker’s evaluation and results with visual interpretation. The preliminary evaluation of the Excel tool was carried out by students. It showed that it is useful and easy in use. And the students' opinions on the computerized tool for ergonomic risk evaluation are very encouraging and promise what was presented in this study.

Due to the wide scope, many participants and long construction time of project, the risk of EPC general contracting is far greater than the common engineering contracting. So it needs objective, accurate and reasonable evaluation. Through the EPC contracting risk evaluation index and extension analysis and correlation functions, this study establish the Extension Element model which contributes to evaluate the risk of EPC contracting. On the other hand, this paper put forward objective and comprehensive risk evaluation results and the level of risk to assist decision makers.
