Opis:
This article addresses integrated functional safety and cybersecurity analysis with regard to: the generic functional safety standard IEC 61508 and the cyber security standard IEC 62443 concerning an industrial automation and control system (IACS). The objective is to mitigate the vulnerability of information technology (IT) and operational technology (OT) systems, and reduce relevant risks taking into account a set of fundamental requirements (FRs). A method is proposed for determining and verifying the performance level (PL) or the safety integrity level (SIL) of defined safety functions, and then validating these levels depending on the security level (SL) of a particular domain,e.g.a safety related control system (SRCS). The method is general in the sense that it is based on risk graphs prepared for individual risk and/or societal/group risk with regard to the criteria defined.

Opis:
Even the best technology will be ineffective if not used appropriately, therefore education and training about cybersecurity principles and programs are essential components of any cybersecurity strategy. This article presents selected models of the decision support theory from the point of view of cybersecurity education. The analysis of scientific literature and the available research results serve as a base to characterize approaches to raise the awareness of decision-makers about potential cyber threats and the development of appropriate attitudes and the conscious use of information systems and digital resources. The main part of the article is devoted to the issue of the use of teaching methods to increase the involvement of learners. It also describes examples of selected models of the game theory used in IT security education, including examples of simulation games dedicated to decision-making in the domain of IT security.

Opis:
In the maritime transport, the Electronic Chart Display and Information System (ECDIS) has been developed into a complex computer-based ship critical operational technology system, playing central roles in the safe ship navigation and transport. While ECDIS software maintenance is regulated by the International Maritime Organization (IMO) ECDIS performance standards and related circulars, underlying software and hardware arrangements are implemented by ship-owners and supported by ECDIS equipment manufacturers. In this paper, we estimate ECDIS cyber security in order to study the origin of ECDIS cyber security risks. A set of ECDIS systems is examined using an industry-leading vulnerability scanning software tool, and cyber threats regarding the ECDIS backup arrangement, underlying operating system and third party applications are studied.

Opis:
The article presents an approach to data anonymization with the use of generally available tools. The focus is put on the practical aspects of using open‐source tools in conjunction with programming libraries provided by suppliers of industrial control systems. This universal ap‐ proach shows the possibilities of using various operating systems as a platform for process data anonymization. An additional advantage of the described approach is the ease of integration with various types of advanced data analysis tools based both on the out‐of‐the‐box approach (e.g., business intelligence tools) as well as customized solutions. The discussed case describes the anonymiza‐ tion of data for the needs of sensitive analysis by a wider group of recipients during the construction of a predictive model used to support decisions.

Opis:
Aim: Blockchain technology (BCT) is a relatively new technological development, promising strong gains in the areas of product traceability and visibility, end-to-end coordination (E2E), governance, and efficiency of supply chains. The aim of this study is to gain a better understanding of the impact of BCT on these performance measures. Design / Research methods: Hypotheses were tested with survey data from 119 supply chain professionals from Northern American SMEs. Conclusions / findings: The results confirm the positive impacts of BCT on all performance measures. E2E coordination is the integration of information, goods, and money within an organisation or supply chain. E2E coordination appeared to benefit from the use of BCT, enabling information sharing in a safe way. The findings suggest that BCT use fosters E2E coordination, which in its turn also positively affects financial performance. Originality / value of the article: Despite the increasing interest in and use of, BCT, there is little empirical evidence for the effect on supply chain performance. Many studies are anecdotal and lack empirical evidence. Implications of the research (if applicable): Companies should acknowledge the impact of BCT use on the various supply chain performance measures. Implementing and using BCT is likely to foster improvement in a wide range of performance indicators.   Limitations of the research  (if applicable): Companies use different types, versions, varieties, and forks of blockchain, all having their own strong and weak points. Future studies could investigate and include the nuances within different forks of BCT.

Opis:
In connection with the increase in the price of fuel based on hydrocarbons, the search and use of alternative types of fuel for machines in the mining and oil production industry is quite relevant today. Most of the existing alternative fuels by themselves cannot be considered as ready-to-use motor fuels. One of the ways to solve this problem is to use their mixtures with commercial fuels in certain ratios. This work deals with the development and research of the main characteristics of the mixer for obtaining mixed fuels based on diesel fuel and soybean oil, as well as the results of the study of the physical and operational properties of the obtained mixtures of different volume ratios of diesel fuel and soybean oil. The process of obtaining a mixed alternative fuel based on diesel fuel and soybean oil was implemented on a developed installation consisting of a mixer, the design of which is protected by a patent of Ukraine, and a gear pump. The study of the characteristics of the mixer as part of the installation showed that at a temperature of the components of the alternative fuel of 20°С, with a loss of full pressure on the mixer Δр ≈ (60-65) kPa, the volume consumption of soybean oil reached 10.7.10-6 m3/s. The time of preparation of the fuel mixture in the amount of 195 liters with a content of soybean oil of 10% ranged from 30 to 33 minutes. As research has shown, mixing soybean oil with diesel fuel in the amount of 5-50% vol. provides an improvement in viscosity-temperature properties and makes it possible to use such mixtures in diesel engines without changes in the design of the power supply system and regulation of fuel equipment, which characterizes soybean oil as a promising additive to diesel fuels to improve their technical and operational performance.

The aim of this paper was to present the results of an evaluation of the effect of knowledge-oriented management and level of information technology on the operational effectiveness in Polish hospitals. The data were collected using a questionnaire survey carried out among managers in Polish hospitals. Structural modelling was employed to analyse the data collected. The structural model proposed in the study turned out to fit the data very well, thus demonstrating the positive and cause-and-effect correlations between the level of IT, knowledge-oriented management and operational effectiveness in Polish hospitals.
