Globalization remains the most common and quite controversial concept in modern social discourse. Within the theoretical and conceptual sociological dimension, the authors analyzed the essence of economic globalization (EG) as its defining type. They studied globalization as an objective process (first of all, the international division of labour) and the subjective process of forming a global capitalist economy under the auspices of leading Western countries, supranational financial and economic institutions (primarily the World Bank and the IMF), TNCs. As the main drivers of globalization, they determine its forms and directions in the interests of the "core" of global capitalism. Within the empirical sociological dimension of EG (which involves measuring the various manifestations of the EG process itself as well as its social consequences), the authors paid particular attention to the analysis of social changes in Ukrainian society. The capitalization of the Ukrainian economy, which took place in parallel with Ukraine’s entry into the global economic space, led to degradation of the national economy, significant deterioration of living standards of most citizens, creation of anti-social state with the systemic crisis as its main attribute. To prove these conclusions, the authors analyzed the dynamics of the principal macroeconomic and sociological indicators of Ukrainian society’s life for almost 30 years of drift to the roadside of the global capitalist world, based on the study of numerous domestic and foreign sources. The authors focused on the research of eight critical areas of social changes: deindustrialization of the economy, global competitiveness and innovation, GDP dynamics, employment, income and welfare of the population, socioeconomic inequality, debt dependence and degradation of Ukrainian science. The analysis shows the need to abandon the neoliberal paradigm of development and search for the alternative and more fair models of EG.

The creation of the Zone of Peace and Cooperation of the South Atlantic (ZPCSA) in 1986 and the Gulf of Guinea Commission (GGC) in 2001 was about changes in the distribution of world power. This article argues that though they emerged at different times, their strategic orientation converges in a number of areas related to the significant interests in the South Atlantic as an area of stability in the region to be marked by strong political, economic and military ties. They also converge on the ideal for development, security and greater projection of power and influence in international affairs. The South Atlantic being a route of passage and trade, as a means of access and flow of energy products, the region became a site for new calculations of regional strategic powers about world affairs. The article also argues that ZPCSA and GGC are therefore crucial for the regional order and the development of higher capacities for cooperation on strategic issues. The actual point of convergence extends to ensuring the sovereignty through dialogue between the states in the region that are involved.

Sufficient supply of woodworking with raw materials while preserving the ecology and rational use of wood is a necessary condition for the functioning of the woodworking industry as one of the key segments of the national economy. The issue is of particular importance given the deepening of world integration processes and the introduction of a moratorium on timber exports from Ukraine. It actualizes the study of the state and dynamics of the formation of raw materials potential of domestic woodworks. The purpose of the article is a structural and dynamic assessment of the economic and environmental aspects of formation of the resource potential of Ukrainian woodworks in comparison with the countries of the European Union, as well as in the regional section by types of wood. In the structure of merchantable wood harvested in Ukraine, fuel wood share increased by 4.3 pp. during 2011-2016, whereas in 2017 it increased by 3.8 pp. compared to 2016 and amounted to 61.4%. Unlike in Ukraine, in the vast majority of EU countries business timber is the basis of the structure of harvested merchantable timber. Thus, in the neighboring countries with similar forest landscape – Poland and the Czech Republic – the share of fuel wood in 2017 was 11.6% and 12.3%, in Slovakia – only 6.3%, and in the EU as a whole – 23. 2%. Hence, the significant deterioration of the structure of the harvested merchantable timber in Ukraine can be interpreted as a threat to environmental, and therefore to national security. On the other hand, the results of the assessments revealed an increase in the volume of commercial timber harvesting in Ukraine (in 18 regions) in 2018, as well as in the level of forest reproduction in the leading regions from the harvesting of merchantable timber (Zhytomyr, Kyiv and Rivne regions) and a decrease in the death rate. The restoration of the logical patterns between the dynamics of the loss of stands and the harvesting of commercial and fuel wood are signs of the beginning of positive tendencies in ensuring the preservation and rationalization of raw potential of domestic woodworks and, at the same time, improving the conditions for deepening the level of wood processing. Further authors’ research in this area will be devoted to the search for effective forms of wood industry development in Ukraine, in particular in the Western region.

Abstract. In Ukraine, among the causes of death because of digestive tract diseases, alcoholic liver disease (ALD) has the second place. Due to the significant prevalence of obesity and the growing incidence of ALD, methods are being sought to prevent the progression of the pathological process in the liver, the occurrence of complications and to improve the quality of life of such patients. The aim of the study: to examine the effect of complex treatment with ademethionine, arginine glutamate and rosuvastatin on changes in lipid and carbohydrate metabolism in patients with alcoholic liver cirrhosis (ALC) in combination with obesity. Methods. The study included 156 patients diagnosed with ALC in combination with obesity, including 18 women and 138 men aged (45.3±8.9) years and a median duration of disease (5.1±2.8) years. Patients were divided into subgroups depending on the stage of Child-Pugh decompensation and depending on the applied treatment. Results. At the stage of decompensation, lipid metabolism and leptin levels were low, which indicates the depletion of body fat depots as the disease progresses. It may be due to the progression of the liver dysfunction, as it is actively involved in regulating the formation, destruction and accumulation of fats. Changes in carbohydrate metabolism in patients with ALC in combination with obesity were characterized by a significant increase in IRI, HOMA-IR index and a decrease in the QUICKI index, indicating the presence of insulin resistance (p<0.05). In determining the adipocytokine values, it was found that in decompensated liver function, the leptin rates decreased and the levels of adiponectin increased. Higher leptin content in the stage of compensation and subcompensation is also associated with increased secretion of adipose tissue. At the stage of decompensation, fat depots are depleted, so leptin levels are reduced. This decrease is directly related to the Child-Pugh and MELD scores. Adiponectin levels were decreased in the stage of compensation and increased with the progression of the disease and correlated with disease severity and the MELD score. It is thought that an increased adiponectin level indicates the level of anti-inflammatory reaction in response to hepatocyte damage. Significant deterioration in carbohydrate metabolism, adiponectin and leptin in patients receiving basic treatment was accompanied by deterioration of their condition and increased the risk of 3-month mortality. After the course of treatment in patients of group receiving ademethionine, arginine, glutamate and rosuvastatin at the stage of compensation and subcompensation, the rates of lipid, carbohydrate metabolism, adiponectin and leptin significantly improved and differed from those in patients receiving basic treatment and combination of basic treatment, ademethionine and arginine glutamate (p<0.05). At the stage of decompensation in the scheme with the inclusion of rosuvastatin it was possible to normalize the levels of HDL cholesterol, VLDL cholesterol, atherogenic coefficient and leptin, reduce the levels of adiponectin, IRI, HOMA-IR, HbA1c and increase the QUICKI index, which was accompanied by a decrease in Child-Pugh severity score and 3 month mortality MELD score. Conclusions. In patients with ALC in combination with obesity, the inclusion in the treatment of ademethionine, arginine glutamate and rosuvastatin helps to improve the course of the disease according to the lipid and carbohydrate metabolism, Child-Pugh and MELD scores.

The aim of the article was to present the changes in the profitability of milk production in farms associated in EDF and situated in Poland and selected European countries in 2006–2012. It was found that after the Polish accession to the EU, the situation has improved for milk producers – economic and production results have risen. In 2008–2009, there was a significant deterioration in the profitability of milk production due to, among others, significant declines in milk prices. Since 2010, gradual improvement of the situation is observed. Similar changes occur in dairy farms in other European countries, such as Germany, France and the United Kingdom. This shows how big the interconnectedness between countries is and that the situation of agricultural producers in Poland does not depend only on the local and national market fluctuations, but primarily on fluctuations in the European and global markets.

The objective of this study was to determine the requirements for steels used as construction materials for chemical apparatus operating at an elevated temperature and to correlate them with the properties of the tested steels. The experimental part examined the influence of the annealing process on the structure and properties of X2CrNiMoN22-5-3 (1.4462) and X2CrNiMoCuWN25-7-4 (1.4501) steel. Heat treatment was carried out on the tested samples at a temperature of 600 °C and 800 °C. Changes were observed after the indicated time intervals of 250 and 500 h. In order to determine the differences between the initial state and after individual annealing stages, metallographic specimens were performed, the structure was analyzed using an optical microscope and the micro-hardness was measured using the Vickers method. Potentiostatic tests of the samples were carried out to assess the influence of thermal process parameters on the electrochemical properties of the passive layer. An increase in the hardness of the samples was observed with increasing temperature and annealing time, the disappearance of magnetic properties for both samples after annealing at the temperature of 800 °C, as well as a significant deterioration in corrosion resistance in the case of treatment at a higher temperature.

AbstractSystemic sclerosis (SSc) is a rare connective tissue disease associated with rapid evolving interstitial lung disease (ILD), driving its mortality. Specific biomarkers associated with the progression of this lung disease are highly needed. We aimed to identify specific biomarkers of SSc-ILD to predict the evolution of the disease. For this, we compared prospectively serum levels of several biomarkers associated with lung fibrosis in SSc patients (n = 102), among which SSc-no ILD (n = 63) and SSc-ILD (n = 39), compared to healthy subjects (HS) (n = 39). We also performed a longitudinal study in a subgroup of 28 patients analyzing biomarkers variations and pulmonary function tests over a period of 2 years. Serum level of IGFBP-2 was significantly increased in SSc patients compared to HS, and negatively correlated with pulmonary function (assessed by carbon monoxide transfer coefficient (KCO)) (r = − 0.29, p < 0.01). Two-year longitudinal analysis in a subgroup of 28 SSc patients determined that IGFBP-2 variation was positively correlated with KCO at 2-year follow-up (r = 0.6, p < 0.001). SSc patients with a lower variation of IGFBP-2 (less than 22%) presented significant deterioration of pulmonary function at 2-year follow-up (p < 0.01). ROC curve analysis enabled us to identify that baseline IGFBP-2 > 105 ng/ml was associated with a poor outcome (KCO < 70% predicted) at 2-year follow-up (AUC = 0.75, p < 0.05). We showed for the first time that serum levels of IGFBP-2 might be a prognostic factor of the development of SSc-ILD.

AbstractUrinoma is defined as the extravasation of urine from any part of the urinary collecting system, which causes lipolysis of the surrounding fat, resulting in an encapsulated collection. The most common cause of urinoma is the direct obstruction of the urinary system. The other etiologies include trauma and postinstrumentation/surgery. Parenchymal cause for spontaneous urinoma is exceedingly rare. We present a case of a 30-year-old gentleman who presented with lower abdominal pain and was treated with a Diclofenac injection. The pain got better temporarily, but he presented again with right loin pain after 3 days. His computed tomography scan images revealed bilateral perinephric urinoma. As there was significant deterioration of renal function, he underwent a renal biopsy. The histopathology was reported as acute interstitial nephritis (AIN). Drug-induced AIN is very rarely presented with acute loin or abdominal pain due to spontaneous perinephric urinoma, as it was seen in our case.

BackgroundUnderstanding trends in public attitudes towards people with mental illness informs the assessment of ongoing severity of stigma and evaluation of anti-stigma campaigns.AimsTo analyse trends in public attitudes towards people with mental illness in England and Scotland using Department of Health Attitudes to Mental Illness Surveys, 1994–2003.MethodWe analysed trends in attitudes for 2000 respondents in each survey year (6000 respondents in 1996 and 1997) using quota sampling methods and the adapted Community Attitudes Toward the Mentally Ill scale.ResultsComparing 2000 and 2003, there was significant deterioration for 17/25 items in England and for 4/25 items in Scotland. Neither country showed significant improvements in items between 2000 and 2003.ConclusionsPublic attitudes towards people with mental illness in England and Scotland became less positive during 1994–2003, especially in 2000–2003, and to a greater extent in England. The results are consistent with early positive effects for the ‘see me’ anti-stigma campaign in Scotland.
