Radiation pollution as a threat to the environmental security of the Russia

The topic of the article is relevant — the problem of radioactive waste management, since the task of increasing the level of security of organizations of the country’s nuclear power-industrial complexes is one of the priorities for ensuring state and public security in the National Security Strategy of the Russian Federation. The growth of radioactive waste is a hazard to human health and the environment. The state needs a unified regulation of the radioactive waste management policy and prevention of radioactive disasters.

Carbon dioxide utilization and circular economy: The world, Russia and the Arctic

Sustainable development of regions, territories, and industrial complexes is becoming increasingly important in the context of global environmental challenges. The practical realization of the sustainability challenges depends more on the implementation of specific technologies, including greenhouse emission mitigation technologies. Today, the development and scaling out of CC(U)S (carbon capture, utilization and storage) technologies seems to be one of the most realistic ways to reduce CO2 emissions. The role of CO2 is changing in the context of circular economy principles, it is no longer considered as industrial waste, but as a valuable resource. The aim of this paper is to analyze and assess the prospects for carbon dioxide utilization, as well as the cost-effectiveness of CC(U)S initiatives (using the example of a CO2-based methanol production project in Iceland) in order to explore the prerequisites and opportunities for the development of such projects in the Arctic. In order to assess the spread of technology worldwide, an analysis of foreign experience in implementing such initiatives is presented, as well as the main promising ways of carbon dioxide utilization and their key features are identified. The economic efficiency of the CO2-based methanol production project (by the example of a commercial project in Iceland) is substantiated. A general vision of the prerequisites and opportunities for the implementation of CC(U)S initiatives in the Arctic regions is presented.

Problems of restoration and development of urban environment of old industrial centers]

The paper considers the urban development and reconstruction of industrial centers on the example of different cities. Design proposals are given for the renovation of the Russian factories and landscaping of industrial historic cities. Examples are given for the reconstruction of silk weaving enterprises near Moscow. Many factories are now in a derelict condition, and for the normal urban development need revitalization of enterprises and comprehensive improvement of adjacent areas. Thanks to the development of cloth production, small settlements in central Russia became industrial city-forming centers more than two hundred years ago. Small manufactories were transformed into large industrial complexes, and the unique exquisite fabrics surpassed the best European ones in price and quality. Russian fabrics were universally welcomed at international exhibitions, awarded with medals and long-term orders. Cities were growing, the economy was developing, housing construction helped to solve social problems, transportation and infrastructure of cities and settlements were developing. Early in the 21st century, glorious weaving factories became an integral part of historic cities, their decoration and pride. Architectural ensembles of industrial enterprises became not only monuments of the Russian cultural heritage, but also an important component of the Russian cities.

Methodological Support of the Competitiveness Management of the Machine-Building Complex of the Republic of Belarus on the Basis of the Strategic Business Units Creation

In the context of a rapidly changing economic reality, the management of large industrial complexes at the macro level has been become increasingly complex and difficult to predict. Directly, the ability to find, create, and combine new and existing conceptual foundations of management policy that have not been used before, but take into account the trends and features of certain socio-economic systems provides an opportunity to develop and create a flexible, adaptive management competitive mechanism that allows, depending on the circumstances, both to re-develop the system from the inside and adjust it to the existing conditions of the macro-environment. Thus, management becomes the main strategic resource that ensures the competitive advantage of the socio-economic system, as well as its’ “survival”, adaptation, transformation and development. The machine-building complex of the Republic of Belarus is an example of a multidimensional volumetric socio-economic system that requires large management costs to increase and strengthen its competitive capabilities and potential. This article is devoted directly to the development of methodological tools for managing the competitiveness of the machine-building complex of the Republic of Belarus, taking into account the features and conditions of its functioning.

Temporal and Spatial Water Quality Assessment for Rivers in Metropolitan Areas Using Multivariate Statistics and Water Quality Indices: A Case Study of the Geumho River, Korea

The Geumho River in South Korea passes through a metropolitan area with a high population density and multiple industrial complexes and, therefore, the water quality of this river is of significance for human health and economic activities. This study aims to assess the water quality of the Geumho River to inform river water quality management and improve pollution control using multivariate statistics and the Korean Water Quality Index (KWQI). Principal component and factor analysis identified those factors related to organic pollutants and metabolism (principal factor 1), and phosphorus and fecal coliform content (principal factor 2). In a cluster analysis, time was considered by distinguishing between seasons (spring, summer, autumn, and winter) and space was considered based on upstream (US), midstream (MS), and downstream (DS) river sections. Seven temporal variables and six spatial variables were extracted from the discriminant analysis (DA) results; the most important water quality variables were high during the spring and summer seasons and in the MS and DS regions. Temporally, the KWQI was highest in winter (70.9) and lowest in spring (59.2), whereas spatially, KWQI values were highest in the US (67.5) and lowest in the MS (56.4) sections. These results indicate that to be most effective, water management interventions in the Geumho River should focus on the urban midstream section and spring seasons.

DOMESTIC AND FOREIGN TYPES OF REDEVELOPMENT OBJECTS FOR HOUSING

Manufacturing has historically been the driving force behind economic growth and structural change. During the financial and economic crisis, governments in Europe provided short-term assistance to industries that had fallen into disrepair by converting them into market-oriented industries (such as steelmakers and car manufacturers). As cities grow and the density of megacities increases, the need for their "renewal" began to appear, which is characterized by the transformation of non-functional buildings and old abandoned buildings for the purpose of further operation. The state and private organizations were interested in the transformation of such territories and actively invest in these projects. Industrial complexes are transformed into areas with residential apartment buildings and offices, their own social infrastructure, transport, entertainment reflecting the needs of modern society. In the future, urban areas can benefit greatly from new opportunities. All over the world, industrial territories are an integral part of cities. The article discusses the experience of reconstruction of industrial zones in Russia and abroad. The industrial heritage is adapting to the new context of the city, using the principles of sustainability, economy and aesthetics
