The paper considers the peculiarities of the SCADA (energy infrastructure management system in the railway infrastructure), as well as issues of the overall dependability in the corporate infrastructure, which is the aim of the study. The study, based on the accepted structure and values of the parameters, examines what depends on and how the readiness factor of a SCADA system changes when the recovery intensity changes and at a fixed failure rate. The results show that with increasing recovery intensity, the readiness factors of the telecommunications network and SCADA system thus defined increase, while reducing the downtime. For a more in-depth study of the overall reliability of the SCADA system, it is necessary to set specific normatively accepted dependability parameters of all connected elements, as well as a real set structure. Based on the fact that with backup resources provided, a defined dependability of the system can be ensured at preset values of the reliability parameters of its components and the backup structure; the opposite problem can also be solved. The proposed approach for studying the reliable behavior of the SCADA system within the corporate infrastructure can be noted as a contribution of the present work and conclusions are made for the practical use of the results.

The accident involving an American Airlines Boeing 757 that crashed on approach to Cali. Colombia, in December 1995, was examined to better understand the errors that the pilots committed. Their loss of situation awareness about their proximity to terrain resulted from several factors involving their use of the flight management system under high workload conditions. The implications of FMS use on our understanding of situation awareness and decision making are explored.

Currently one of the most important problems facing biobanking specialists is the standardization of biobanks operation. Close attention is paid to this issue by international biobanking organizations, such as ISBER and BBMRI-ERIC, which develop regulatory documentation in this area. The article provides examples of standardization tools - implementation of the ISO 9001 quality standard and ISBER Best Practices. General information about the development, scope, and structure of the ISO 20387 standard is provided. The standard does not provide ready-made solutions and does not contain specific requirements for storage temperature or biosamples processing in biobanks, allowing each biobank to adapt its own management system to existing conditions and needs. The standard contains requirements for both the organization of the biobanking and the supporting processes - personnel competence; requirements for biological safety; infrastructure management, including equipment used by the biobank, environmental parameters that affect the storage of biomaterial. The standard contains requirements for the quality management system of biobank, as a necessary element of the organization of any biorepository. At the initiative of the Russian National Association of biobanks and biobanking specialists (NASBIO), development of the Russian standard GOST R ISO 20387 «Biotechnology. Collection and storage of biological samples in biobanks. General requirements» is included in the plan of the National Standardization Program for 2020 by order of Rosstandart No. 2612 of 11/01/2019. Implementing quality standards is a long and painstaking process that requires the involvement of all employees and certain resources. However, the effectiveness of strict compliance exceeds the cost of developing, implementing and maintaining management systems, as it significantly increases the confidence of researchers in the work of biobanks, guarantees high quality of biospecimens and associated data, and creates opportunities for cooperation, both at the national and international level, based on the application of common quality standards in the work.

Broken rails are the most common cause of severe freight-train derailments on American railroads. Reducing the occurrence of broken-rail-caused derailments is an important safety objective for the railroad industry. The current practice is to periodically inspect rails using non-destructive technologies such as ultrasonic inspection. Determining the optimal rail defect inspection frequency is a critical decision in railway infrastructure management. There is a seasonal variation in the occurrence of broken rails that result in train derailments. This paper quantifies the effect of this seasonal variation on the risk-based optimization of rail inspection frequency. This research can be incorporated into a larger framework of broken rail risk management to improve railroad transportation safety.
