The study is relevant due to the current situation with fires and integral fire risk indicators in the municipalities. Man-made fires have been a source of increased danger to health and lives of the population, causing great material damage. Fires are a direct threat to the demographic situation in the region since they cause premature mortality. For households, fires undermine social status, destroy social units, cause moral harm aggravating stress, which provokes illnesses. From the technical point of view, man-made fires create risks for dilapidated houses and facilities that do not meet the fire safety requirements. The Republic of Buryatia is a region with a weak degree of industrial development and a vast territory with a low distribution of settlements, i.e. considerable remoteness from the regional centers. The impact of fires (which make up 99% of all types of emergency situation) on the social well-being of the population is studied. Based on the methodology and calculations of fire risks by the number of fires, injured and killed, material damage and destroyed buildings, it was established that the level of protection of residents of Buryatia from fire risks is insufficient. The indicators should encourage the government to develop and implement effective safety measures.","PeriodicalId":322608,"journal":{"name":"XXI Century.

One of which is polluting underground and surface waters. The purpose of the article is to assess the level of pollution of water bodies of the Denezhkin Kamen reserve by the Shemur ore field. To assess the level of pollution, individual and complex pollution indices, statistical parameters and the ʺQuartileʺ method for calculating emissions are used. An analysis of the geological structure of the territory and physical and geographical conditions of the area was carried out; the level of pollution was assessed; the main causes of pollution were determined; the main pollutants were identified. The waters flowing through the reserve are not polluted they are polluted near the reserve borders. Pollutants are carried downstream over long distances and get into the intakes of local settlements. In the Bannaya River basin, the pollution area is about 80 km; in the Olkhovka River basin, the pollution area is about 60 km. There is a dependence in the change in the concentration of pollutants on seasonality and weather conditions. The main pollutants are those that are contained in large quantities in the overburden rocks of the deposit. Additional studies are required using a sampling program, which was not available during the current studies.","PeriodicalId":322608,"journal":{"name":"XXI Century.

Studies aimed at developing methods for investigating the impact of industrial facilities on the air is of interest. The purpose of this work is to analyze the methodology for assessing the risk of exposure of a technosphere object to the atmosphere. It was assumed that the enterprise in emergency mode emits pollutants through the source of emissions at the maximum single concentration of the substance exceeding the maximum permissible concentration. To calculate the impact on a human, various scenarios of an emergency situation are taken into account. These are constructing failure trees and using well-known health risk assessment techniques. The calculation took into account the wind rose for a specific enterprise location and wind speed projections obeying the normal distribution law. These assumptions allowed us to develop a method for calculating the risk of exceeding the concentration of a pollutant at a given point (x, y) during the year. Isolines of surface concentrations were built. Three toxic substances were taken for analysis. The method for calculating the dispersion of emissions of harmful (polluting) substances in the atmospheric airwas used; maps of the dispersion of isolines of pollutants in residential areas were constructed. When solving the inverse problem, emergency emission intensities at which excess of permissible concentrations occurred were determined. In the range of multiplicities exceeding the maximum single maximum permissible concentration from 1 to 5, the dependence was well approximated by a straight line. This technique can be used to determine the risk of diseases caused by carcinogenic and noncarcinogenic substances and minimize the risk of exposure to harmful substances. Ash and slag wastes are the source of negative impact on the environment. This area is studied by a number of researchers. The article aims to systematize the data on possible applications, accumulated practical experience of using ash and slag waste in agriculture both in Russia and abroad. The analysis showed that waste from the fuel and energy industry can be widely used in various areas of agriculture. It can be used as ameliorants, zeolite-based mineral fertilizers, pesticides and insecticides for treating horticultural crops, microfertilizers, as well as for soil remediation and land reclamation. The use of ash and slag waste in agriculture and other sectors of the national economy can reduce the ecological load on the environment. The number of overfilled ash dumps can be reduced, and there will be no need to build new ones.","PeriodicalId":322608,"journal":{"name":"XXI Century.

Recommendations on reduction of the burnout syndrome impact are provided. The assessment was conducted using the professional burnout diagnostics method by K. Maslach and S. Jackson adapted by N.E. Vodopyanova. The burnout syndrome is considered to be a three-dimensional component consisting of emotional exhaustion, depersonalization, and personal achievement reduction. The study involved Irkutsk regional newspapers, radio broadcasting, television and Internet media. A total of 155 people participated were surveyed: 113 females and 42 males. Most of them suffer from the professional burnout syndrome. To verify the results obtained, age and work experience were taken into account. According to the results obtained, the degree of depersonalization increases with aging. The longer the participant works, the stronger the depersonalization component. The personal achievement reduction also depends on these components. The younger the editorial staff member and the shorter his/her work experience, the stronger the negative self-esteem, underestimation of own professional achievements and success. Conversely, the more mature the journalist is, the more positively he evaluates his professional competence and creativity. At the same time, emotional exhaustion manifests itself in all respondents, regardless of their age: in two studies, the average and high degrees were revealed. It is this component that makes a contribution to the professional burnout of journalists. To reduce the impact of the syndrome, a set of preventive measures has been developed. They can prevent economic and resource losses, and increase labor productivity. The methods of preventing professional burnout are aimed at preventing emotional exhaustion, and in extreme cases - at relieving negative symptoms and combating negative consequences. They can improve productivity of media workers and reduce psychosocial risks.","PeriodicalId":322608,"journal":{"name":"XXI Century.

It is proposed to abandon the main modes of vibration in the calculations, i.e. the coefficient ηir of the waveform and the vibration frequency of the residential building and the foundation during earthquakes. Shear and bending calculations of a residential building are based on the design model developed. The values of seismic force are determined by the first and last modes of vibration.
