Introduction.Methanol and its derivatives occupy one of the leading places among the main organic synthesis intermediates in terms of their importance and scale of production. According to experts, by 2027 the global demand for methanol can reach 135 million tons, the annual growth will be about 5.5%. However, there is little information regarding the assessment of working conditions and occupational risks for workers in modern methanol production and its derivatives.The aim of the studyis hygienic assessment of working conditions and the formation of health risks in workers of modern production of methanol and methylamines.Materials and methods.The assessment of the main adverse factors of production is given. When studying the state of health, objective indicators (the results of an in-depth medical examination) and subjective (the results of a quantitative assessment of the risks of the main pathological syndromes associated with health) are considered.Results.According to long-term observations, the concentration of harmful substances in the air of the working area, indicators of labor severity, parameters of physical factors met hygienic requirements, with the exception of industrial noise exceeding the maximum permissible level, as well as labor intensity of 1 degree. The General assessment of working conditions corresponds to the category of harmful 2 degrees (3.2). According to the results of the medical examination and quantitative assessment of the risks of health disorders in workers, the most significant were functional disorders and diseases of the circulatory system. The levels of somatic pathology on the part of the main body systems were significantly higher in apparatchiks compared to the engineering and technical personnel (ETP).Conclusions:In the production of methyl alcohol and methylamines, the main hygienic importance is the impact on workers of the complex of harmful substances of 1-IV hazard classes in low concentrations, increased levels of industrial noise, labor intensity of 1 degree. According to the subjective assessment of health and medical examination, the greatest prevalence of health risks in workers was observed from the circulatory system, and the levels of the revealed somatic pathology were statistically significantly higher in apparatchiks compared with the ETP.

The ongoing climate change requires a quantitative assessment of the impact of weather conditions on the nature and livelihoods of the population. However, to date, the concept of “climate risk” has not been finally defined, and the corresponding terminology is not universally recognized. One manifestation of climate change is an increase in climate variability and extremeness in many regions. At the same time, modern statistics indicate growing worldwide damage from dangerous weather and climate events. The most widely used in climate services is the concept of “Vulnerability index”, which reflects a combination (with or without weighing) of several indicators that indicate the potential damage that climate change can cause to a particular sector of the economy. development of adaptation measures to ensure sustainable development of territories. The main criterion for the vulnerability of the territory from the point of view of meteorological parameters is the extremeness of the basic values: daily air temperature, daily precipitation, maximum wind speed. To fully take into account the possible impacts of extreme climatic conditions on the region’s economy, it is necessary to detail the weather and climate risks taking into account the entire observation network, since significant differences in quantitative assessment are possible. The obtained average regional values of the climate vulnerability indices for the Belgorod Region of the Russian Federation provide 150 points for the winter period, 330 points for the summer season, which indicates the prevalence of extreme weather conditions in the warm season. Most of the territory has a relative influence on climatic phenomena, with the exception of the East and the Southeast Region. Moreover, the eastern part of the region is the most vulnerable in climatic terms.

The Impact

The competitiveness, market value and income of an enterprise depend on the level of intellectual property management. Therefore, the aim of research is to develop, substantiate and test a scientific and methodological approach to a quantitative and qualitative assessment of the management of intellectual property of industrial enterprises.  The originality of the proposed approach is that on the basis of the concept of "management of intellectual property" a procedure for current management has been developed, the main stage of which is a quantitative and qualitative assessment. The assessment is based on the structural and logical model, which is built according to two criteria. The criteria make it possible to determine the current state of the use of intellectual property (intangible assets) – a quantitative assessment, and the prospect of further use (intellectual potential) – a qualitative assessment. A quantitative assessment involves the calculation of indicators characterizing the state of assets, the dynamics of the impact on the market value of the enterprise, the profitability of production, which is proposed to be determined through the net cash flow from operating activities. A qualitative assessment is carried out in terms of components (information and investment, organizational and legal, economic, personnel and motivation), tools and relative indicators that characterize the intellectual potential of an industrial enterprise. The assessment is carried out using a general integral indicator, which is of practical importance, since it shows the existing level of intellectual property management and directions for improvement in the future. The approbation of the scientific and methodological approach was carried out on the example of three Ukrainian coke-chemical enterprises (CJSC Avdeevka Coke Plant, CJSC Zaporozhkoks, CJSC Yuzhkoks) of the American association SUNCOKE ENERGY, INC and the Polish association J.S.W. S.A. Group. Empirical studies for the period from 2015 to 2019 made it possible to build a scale for assessing the level of intellectual property management according to the Harrington function

Rural areas in Serbia occupy about 3/4 of total country territory and they are home for almost half of total population. These areas are characterized by very heterogeneous environment with not expressed anthropogenic negative influence. Because of a few types of the settlements and very rich rural and natural landscapes, there are great opportunities for development of diverse economies, multifunctional use, and a variety of different activities. This chapter discusses rural tourism development in the Region of the Southern and Eastern Serbia and its impact on the urban-rural synergy. The main goal is to investigate the impact of the tourism development on the connections on the relation urban to rural on the example of this region, and to point out importance of this synergy for future balanced rural and regional development. Rural tourism represents drive for urban-rural synergy and it is one of the key factors of rural development.

AbstractIn accordance with Article 15 of the Aarhus Convention, the first meeting of the parties to this Convention established a non-judicial and consultative Compliance Committee to consider, among other matters, individual cases concerning compliance by parties with their obligations. The Committee is traditionally viewed as a non-judicial, soft mechanism and its rulings as non-binding, soft law. In recent years, however, to support the claim that rulings of the Committee have an impact and legal effects, some scholars have departed from the traditional perspective and characterized the Committee as a more judicialized mechanism, which issues legally binding rulings.This characterization assumes a correlation between judicialization and binding effect on the one hand, and legal effect on the other. The latter claim, however, has not been supported by a systematic assessment of the impact of the Committee's rulings on domestic practice. Against this background, the article assesses the impact of Article 9-related rulings of the Committee, issued between 2004 and 2012, on national legal orders. The assessment reveals that in fewer than 41% of the cases parties recorded some degree of compliance with the rulings of the Committee, whereas in 59% they recorded no progress. The quantitative assessment and respective qualitative insights, among other factors, suggest that the normative character of the Committee and its rulings play an auxiliary role in the process of ensuring compliance with the provisions of the Aarhus Convention. The decision of parties to comply is determined typically by the substance of the rulings as they stand in relation to domestic circumstances rather than by the institutional features of the Committee and binding effect of its rulings.

SUMMARY Although many studies have revealed that the atmospheric effects of electromagnetic wave propagation (including ionospheric and tropospheric water vapour) have serious impacts on Interferometric Synthetic Aperture Radar (InSAR) measurement results, atmospheric corrections have not been thoroughly and comprehensively investigated in many well-known cases of InSAR focal mechanism solutions, which means there is no consensus on whether atmospheric effects will affect the InSAR focal mechanism solution. Moreover, there is a lack of quantitative assessment on how much the atmospheric effect affects the InSAR focal mechanism solution. In this paper, we emphasized that it was particularly important to assess the impact of InSAR ionospheric and tropospheric corrections on the underground nuclear explosion modelling quantitatively. Therefore, we investigated the 4th North Korea (NKT-4) underground nuclear test using ALOS-2 liters-band SAR images. Because the process of the underground nuclear explosion was similar to the volcanic magma source activity, we modelled the ground displacement using the Mogi model. Both the ionospheric and tropospheric phase delays in the interferograms were investigated. Furthermore, we studied how the ionosphere and troposphere phase delays could bias the estimation of Mogi source parameters. The following conclusions were drawn from our case study: the ionospheric delay correction effectively mitigated the long-scale phase ramp in the full-frame interferogram, the standard deviation decreased from 1.83 to 0.85 cm compared to the uncorrected interferogram. The uncorrected estimations of yield and depth were 8.44 kt and 370.33 m, respectively. Compared to the uncorrected estimations, the ionospheric correction increased the estimation of yield and depth to 9.43 kt and 385.48 m, while the tropospheric correction slightly raised them to 8.78 kt and 377.24 m. There were no obvious differences in the location estimations among the four interferograms. When both corrections were applied, the overall standard deviation was 1.16 cm, which was even larger than the ionospheric corrected interferogram. We reported the source characteristics of NKT-4 based on the modelling results derived from the ionospheric corrected interferogram. The preferred estimation of NKT-4 was a Mogi source located at 129°04′22.35‘E, 41°17′54.57″N buried at 385.48 m depth. The cavity radius caused by the underground explosion was 22.66 m. We reported the yield estimation to be 9.43 kt. This study showed that for large-scale natural deformation sources such as volcanoes and earthquakes, atmospheric corrections would be more significant, but even if the atmospheric signal did not have much complexity, the corrections should not be ignored.
