In the article, based on the analysis of the modern geopolitical situation, assessment of the scale of the impact of aggressive actions of a hybrid nature on the part of the collective West on the socio-economic stability of Russia a methodological approach to forecasting the military-political situation using the military-strategic potentials of the warring states is proposed.

The article presents research materials to test the hypothesis of the expediency of applying a targeted approach to the formation of a system of indicators characterizing regional personnel security, which is the purpose of the study. To achieve this goal, two main tasks were solved: to determine the risks of personnel security in the region (Kirov region) based on an assessment of a system of indicators characterizing the professional level of the region’s labor potential and its dynamics; to develop proposals to improve the level of personnel security in the region through educational activities. To test the hypothesis, general scientific methods of analysis and synthesis were used, as well as a secondary analysis of research results published by Russian scientists on regional personnel security. The presence of disagreements in the composition of personnel safety indicators and methods of their assessment predetermined the need for research on this topic. As a result of the conducted research, there were four main conclusions. Firstly, to determine regional personnel security, it is advisable to apply a functional approach and consider it as a subsystem of regional economic security in the form of a process aimed at minimizing personnel risks. Secondly, all the many factors affecting regional personnel security can be divided into four groups: economic, demographic, social and technical and technological. The key factor characterizing regional personnel security is the availability of personnel for all enterprises in the region. Thirdly, a shortage of human resources is projected in the Kirov region for the next five years. At the same time, the needs for personnel with a secondary vocational education level exceed three times the needs for personnel with higher professional education. The dynamics of the forecast demand is not uniform, but is characterized by a sawtooth shape.
The analysis of the indicators characterizing the education and training system in the Kirov region allowed us to form a list of regional personnel security risks and proposals for their minimization, which is of practical importance.

The article considers the indicators characterizing the assessment of the risk to public health during the transboundary transport of pollutants (POPs) and their biotransformation. The values of concentrations of these compounds in the atmosphere are given and the fields of their deposition in various regions of the world are shown. Risk assessments for dioxins and dioxin-like compounds are given.

The possible long-term cyclonic energy cyclicity in the long-term chronology of tropical cyclones is considered.

Floods on rivers are dangerous hydrological phenomena and pose a threat of flooding of territories where settlements, economic facilities, including critically important and potentially dangerous ones, may be located. Floods are often caused by the formation of congestion during the opening of rivers, however, forecasting the occurrence of congestion is quite problematic, and in order to protect the population and territories from such phenomena, it is necessary to carry out a sufficiently large set of measures, which leads to high economic costs. The purpose of the work is to substantiate an approach to reduce the likelihood of congestion on the river section by performing preventive engineering and technical measures. The probability of congestion depends on various factors of congestion formation, which have some parameters (characteristics). Statistical processing of data accumulated over many years of hydrological observations allows us to obtain some probabilistic assessment of the occurrence of congestion on the river section, which makes it possible to determine the need and importance of engineering and technical measures to reduce the likelihood of congestion, and with it floods. The article presents an approach to solving the problem of reducing the likelihood of congestion on the river section, taking into account the fact that when performing engineering and technical measures of a preventive nature, the parameters of the factors of congestion formation change. The methods used in the work to obtain a probabilistic assessment of the occurrence of congestion are the analysis of existing approaches for the probabilistic assessment of the occurrence of congestion, multiple regression analysis. Considerable attention is paid to the order of formation of the objective function, based on the processing of statistical data. Based on determining the degree of significance of the influence of particular parameters on the target indicator — the probability of congestion on a river section that can lead to flooding, an algorithm for forming a system of restrictions for the parameters of congestion factors is proposed. As a result, an approach to determining the probability of congestion during engineering and technical measures is presented.

A practice-oriented general approach to the construction, implementation, operation and development of risk and opportunity management systems in corporations, companies, enterprises, firms and organizations is proposed.
At the first stage, a basic version is constructed, including the necessary set of components. Such basic components include: a mandatory set of international, domestic, industry and corporate standards and regulations for the company; a register of major risks; a list of risk owners; a subsystem for risk analysis and assessment and a subsystem for monitoring and risk management.
Various options for creating each necessary component included in the basic version of risk and opportunity management systems are analyzed.
At the second stage, it is proposed to expand the basic option by including additional functionality such as digitized risk and opportunity management systems, its integration into the over-all management system, identification of key risks and opportunities and key risk owners, risk management intellectualization processes, personnel training and implementation of strategic risk management measures.
The proposed practice-oriented approach to the construction, operation and development of risk and opportunity management systems is illustrated by the example of a large scientific and industrial enterprise of the engineering division of Rosatom State Corporation.

The analysis of scientific papers testifies to the numerous advantages of using digital twin technology in the development and application of various products, including samples of emergency rescue equipment. The article proposes a methodological approach to solving the problem of feasibility study of the feasibility of using digital twin system technology at various stages of the life cycle of emergency rescue equipment, based on the method of hierarchy analysis.
