The paper describes the main features of blockchain technology, provides the main areas of use of this technology. Today, blockchain has evolved into a reliable and secure way to store and record transactions across a wide range of application domains. However, the impact of existing solutions on the current network infrastructure needs to be considered. The authors propose to create a system for generating and storing blockchain traffic based on the JavaScript programming language. This solution cannot be applied to cryptocurrencies, but it allows you to evaluate the work of a distributed database based on blockchain technology. The aim of the work is to analyze the delays in the generation and distribution of traffic between various numbers of nodes and the dependence of the speed of distribution and block generation on the performance of computers. The paper also considered the algorithm for joining a new node to the cluster and sending a new block to the blockchain, as well as the scheme of a node in a blockchain cluster, and presented the results of an experiment with a quantitative assessment of network performance characteristics.

The Impact

Modern ideas about comprehensive assessments of the level of health are based on synthetic (complex, integral, multidimensional) indicators, the requirement for which is the need to take into account various (by origin and methods of obtaining) health indicators both at the individual and population, regional levels. In recent years, many methodological methods have been processed to obtain a comprehensive qualitative and quantitative assessment of the state of individual health. Obtaining a generalized qualitative and quantitative assessment remains the most important methodological task of modern theory and practice of public administration and public health. The purpose of the study was to develop a methodology for substantiating intersectoral regional prevention programs and an algorithm for evaluating their effectiveness using the example of a dysplastic-dependent pathology of the bronchopulmonary system in children. In developing and justifying population-based management models for early diagnosis and primary prevention, we used systematic population modeling methods. The expected indicators of the pathogenic and sanogenic effects of the most significant regional and environmental factors of the dysplastic-dependent pathology of the bronchopulmonary system among children are determined. Substantiated models of end results for modification of risk factors and the expected effectiveness of the N-factor regional and environmental program for the primary prevention of dysplastic dependent pathology of the bronchopulmonary system in children. Priority areas for the implementation of regional-population programs for the prevention of dysplastic-dependent pathology of the bronchopulmonary system in children due to the impact on controlled environmental environmental factors are determined. An example of calculating the expected effectiveness of children's health management through interdepartmental interaction at the regional level is given. Prospects for further research on this issue related to a prospective evaluation of the effectiveness of intersectoral programs to reduce the influence of regional environmental factors on the health status of the child population, in particular, dysplastic-dependent pathology of the bronchopulmonary system.

The Impact

Several American utilities have contracted to purchase electricity from ‘windfarmers’, and many others are beginning to explore this option. The value of conventional fuel and capacity savings will influence the terms under which utilities enter these contracts. A quantitative assessment of these savings is undertaken using computer models that simulate the dispatching of conventional capacity and calculate the reliability of this capacity. These models identify the conventional costs avoided by utilities as a consequence of windfarming. The impact of various levels of windmill penetration is simulated in five sites in the USA, representing a wide range of average wind speeds. The cost of wind energy is less than the value of fuel savings alone for utilities which possess substantial oil- and-gas-fired generating capacity and which serve sites with winds above 12 m.p.h. In such sites, 1kW of conventional capacity is displaced by 2–5 kW windmill capacity. Increased windmill penetration reduces the value of fuel and capacity savings per kW.

Maintenance staff fatigue is one of the key factors contributing to the occurrence of errors in the maintenance. The problem of maintenance staff fatigue is a serious challenge for aircraft maintenance organizations, and its solution is directly related to the impact on flight safety. The authors consider the issues of the fatigue effect on the maintenance staff performance and related consequences. The article provides the results of the maintenance staff fatigue research, obtained through a survey of one of the organizations` employees. According to the survey, errors are the most likely outcome of work in a state of fatigue in aircraft maintenance. The obtained results made it necessary to develop a methodology for managing maintenance staff fatigue in aircraft maintenance. The methodology is based on a questionnaire, where the respondents are asked to answer questions regarding their state of fatigue, and fatigue assessment criteria. The assessment results make it possible to develop the necessary corrective and preventive measures, including the privilege limitation and suspension to perform maintenance tasks.
