Authors:   National University of Food Technologies Ukraine, Lysenko Olena
Published: February 2023

The features of calculating the regional human development index in Ukraine at national level are discussed in this article. Research actuality is related to performing periodic evaluation of level of regional human development as a component of social and economic development of Ukraine with an eye to identification of tendencies and adjustments of strategic plans of development of separate regions. The stages of evolution of methodical approaches to the calculation of integral values of indexes of «Decent Work» block are considered. On certain indexes the estimation of working conditions is done. The graphic method RADAR is proposed to use when evaluating the level of regional human development. This method is used for determination of index of competitiveness of regions, and it is based on the calculation of area of the polygon built using the values of indexes. The index is calculated using indicators combined into six blocks (population reproduction; social status; comfortable life; welfare; decent work; education). The indicators of the “Decent Work” block (employment level of the population; unemployment rate; the part of workers whose salary is less than 1,5 of the subsistence minimums; the part of workers who work in conditions that do not meet sanitary and hygienic standards; the ratio of average and minimum salaries; the level of social insurance) are considered and the block is used to evaluate working conditions. The comparative analysis of the received results of calculation of index of regional human development is presented based on two methodical approaches: the simple sum of the standardized values of indexes and the RADAR method. The petalous diagrams are built for the regions-leaders and for outsiders, that were identified as such for investigated period using different methodical approaches. The research of the estimations of level of human development, which received using different methods, showed differences in rating of regions based on indexes of the «Decent Work» block. The results of the performed comparative analysis showed that the different economic and mathematical methods should be used for evaluation of the level of human development in order to justify the administrative decision regarding the further development of working conditions.

The article analyzes the theoretical foundations of the organization of investment activities in small forms of agricultural production in Ukraine. It is noted that one of the features of the national model of agricultural production is the dominance of small forms of Management in a number of sectoral areas, the status of which does not always allow farmers to even potentially receive investment funds. The classification of investment projects in the agricultural sector is proposed according to the following criteria: level of implementation, direction of implementation and duration of implementation. It is noted that each of these areas has its own specifics regarding implementation. There is a lack of a unified approach to determining small forms of familytype agricultural production. The technical and technological direction provides for the introduction of investment projects in order to increase the level of efficiency of resource potential in the production of agricultural raw materials, their further processing, storage and sale. The organizational and economic direction includes the implementation of measures aimed at improving the management system of economic processes on the scale of the business structure, as well as the formation of a system of mutually beneficial relations between various business entities. The social direction of investment projects implementation is not directly related to the production and economic activities of agricultural business entities, but the specifics of this industry direction, its integration into the system of relations between members of local communities make it necessary to study it. The following factors are identified that determine the nature of innovation activities and affect the level of efficiency of investment funds development: the level of marketability; internal non-economic factors; the general nature of the chosen strategy of economic activity, the available resource potential. The presented features of ensuring innovation activity in small forms of agricultural production, in turn, make it necessary to use specific methodological tools to assess the effectiveness of relevant measures. Separately, it should be noted the need to take into account the social component of the functioning of small agricultural formations.

DEMOGRAPHIC CHARACTERISTICS OF UNITED TERRITORIAL COMMUNITIES AND DISTRICTS OF UKRAINE AS A FACTOR OF THEIR INCLUSIVE DEVELOPMENT
Authors:   Odesa National Technological University, Pavlova Iryna
Published: February 2023

The article solves an actual scientific and practical scientific problem related to the definition of the demographic characteristics of the united territorial communities (UTCs) and regions of Ukraine as a factor in their inclusive development. The consolidation of administrative-territorial units of the basic and district levels, which was a consequence of the reform of the territorial organization of society, created the prerequisites for the formation of an inclusive environment within their spatial boundaries with the participation of towns, settlements and villages. Such an opportunity largely depends on certain factors of the inclusive development of UTC and districts, one of which ‒ demographic ‒ is largely derived from the organizational and administrative decisions that were laid at the basis of the reform itself. The purpose of the study is to determine the demographic characteristics of the UTC and regions of Ukraine as a factor in their inclusive development. For her implementation, the following tasks have been formulated: to characterize the essence and phasing of socio-spatial inclusiveness; identify the prerequisites for the inclusive development of the UTC and the districts in view of their demographic characteristics; to reveal the specifics of inclusiveness and its focus in communities and districts of different sizes. In the course of the study, the quantitative composition of all UTC and districts of Ukraine was analyzed, the grouping of these socio-spatial formations according to their demographic indicators was carried out, and the positive and negative aspects of creating an inclusive environment within them. Regional features of inclusive development of communities and districts have been revealed. The specificity of the manifestation of endogenous and exogenous inclusion of socio-spatial agglomeration formations, which became UTC and new districts in the post-reform period, is revealed. It has been proven that the rural or urban focus of inclusive development has a different dimension and manifestation at the level of UTC and districts. It was found out that in the process of formation of the UTC and formation of new districts, certain disproportions arose between these socio-spatial formations according to their demographic characteristics, which significantly complicates the process of achieving inclusion. Based on the results of the research, certain generalizations were made and it was stated that this problem in the conditions of martial law has acquired political acuteness and fateful significance for Ukraine. In view of this, the attention of scientists should be focused precisely on the substantiation of the ways and directions of the post-war recovery of communities and districts on the basis of inclusiveness.

Published: February 2023

The article analyzes the information and communication technologies used by enterprises in the tourism sector to ensure the efficiency of their operation and increase competitiveness. It has been established that each of the types of enterprises is characterized by the use of both specially developed and universal software. This approach is also explained by the fact that for certain components of the internal environment, for example, marketing or finance, universal software can be used, and for the operating room - something that takes into account the specifics of the tourism business. It was determined that in connection with the war in Ukraine, business owners faced the question of replacing software with domestic products, or world-famous ones. To justify the choice among the existing variety and, taking into account the opportunities of the business, the method of weighted assessments was used, which provides an objective assessment and selection of optimal software for travel operators and agencies, hotels, restaurants.

Published: February 2023

The current state and problematic aspects of management of the resource potential of agricultural business entities are disclosed in the article. The conducted studies showed that agricultural producers have certain difficulties in the process of resource potential management. The system of material and technical support of agricultural production needs complex modernization and staffing. Modern mechanisms for compensating part of their cost and financial leasing are quite effective management tools. But, they have significant limitations for their possible use for a significant number of agricultural producers. Dominating traditional business concepts in agricultural management are commercial oriented. They define the prevailing policy of resource management, according to which the demand for biological and eco-remedies remains insignificant, unstable and significantly limited by the price factor. The labor market of the agricultural sector is characterized by significant inclusive gaps. It remains the leader of informal employment with an outflow of labor potential from the industry and a low level of wages. Research has revealed that one of the main reasons for managing the resource potential of agrarian business entities is the lack of financial resources. Own capital remains the main source of financial support for agricultural production. In order to solve these problematic issues, an inclusive model of managing the resource potential of agrarian business based on the action of supply chains has been proposed. The inclusive model is built on mechanisms that provide for the possibility of realizing the interests of all participants in agrarian business, society and rural areas due to the creation of supply chains, the formation of new value and profitability. The implementation of an inclusive business model for managing resource potential should be complemented by the use of modern digital management tools that provide equal opportunities and access to resources. Among them are: professional and educational online platforms, digital HR policy products, crowd-drafting and credit digital, investment and innovation platforms, digital analytical products that will support management decisions. The implementation of an inclusive business model of resource potential management in agricultural management should be based on a deep understanding of the goals and priorities of inclusive development. The latter in a strategic perspective become life-supporting both for business and for future generations.

The rapid spread of globalization processes in the field of finance, active involvement of information technologies and Internet networks for servicing financial transactions contribute to the fact that financial systems of countries around the world are becoming increasingly vulnerable to fraud encroachments. The article discusses the most common types, types and methods of financial fraud in the world. The most dangerous fraud schemes have been studied. The influence of fraudulent actions on the production activity of enterprises, financial activity of banks, and in general the life of ordinary citizens is studied, because financial fraud is a problem with far-reaching consequences in the financial industry, the government, the corporate sector, and for ordinary consumers. The consequences of various types of fraud are analyzed. Statistics are given on the number of frauds committed in areas where they have been exposed or known, as the dependence on new technologies such as cloud and mobile computing increases every minute, which makes the problem very difficult. Suggestions for preventing, evading or preventing fraudulent activities are provided. The essence of financial fraud is revealed through the prism of the financial aspects of this concept, specified purpose, methods and consequences of financial fraud, and is also presented probable set of measures for prevention and minimization of financial fraud as a complete system capable of fundamentally affecting overcoming this socially dangerous phenomenon. Typology of financial fraud by institutional sectors has been carried out economy and depending on the object of fraudulent actions taking them into account rapid modernization and modification, which, unlike the existing classification, will contribute identifying the sectors most "sensitive" to financial fraud national economy and determination of priority and specific directions measures to counter this negative phenomenon. Socio-economic and political instability form a favorable basis for the spread of fraudulent schemes in the field of Ukraine. Nowadays, financial fraud is a significant threat, in particular for domestic business. It is emphasized that in modern realities digital technologies create new threats and challenges for companies and often can be used to implement various types of fraudulent schemes, including cyber attacks, corporate espionage and many others. However, modern technologies can also become an important tool for the protection of domestic ones organizations, the state and citizens from fraudulent encroachments.

Aims

This study examined the diversity and sulfide-producing activity of microorganisms in microcosms containing commercial clay products (e.g., MX-80, Canaprill and National Standard) similar to materials which are currently considered for use in the design specifications for deep geologic repositories (DGR) for spent nuclear fuel.

Methods and results

In anoxic microcosms incubated for minimum of 60 days with 10 g l-1 NaCl, sulfide production varied with temperature, electron donor and bentonite type. Maximum specific sulfide production rates of 0.189 d−1, 0.549 d−1 and 0.157 d−1 occurred in lactate-fed MX-80, Canaprill and National Standard microcosms, respectively. In microcosms with 50 g l-1 NaCl, sulfide production was inhibited. Denaturing gradient gel electrophoresis (DGGE) profiling of microcosms revealed the presence of bacterial classes Clostridia, Bacilli, Gammaproteobacteria, Deltaproteobacteria, Actinobacteria, Sphingobacteriia and Erysipelotrichia. Spore-forming and non-spore-forming bacteria were confirmed in microcosms using high-throughput 16S rRNA gene sequencing. Sulfate-reducing bacteria of the genus Desulfosporosinus predominated in MX-80 microcosms; whereas, Desulfotomaculum and Desulfovibrio genera contributed to sulfate-reduction in National Standard and Canaprill microcosms.

Conclusions

Commercial clays microcosms harbour a sparse bacterial population dominated by spore-forming microorganisms. Detected sulfate- and sulfur-reducing bacteria presumably contributed to sulfide accumulation in the different microcosm systems.

Significance and impact of study

The use of carbon-supplemented, clay-in-water microcosms offered insights into the bacterial diversity present in as-received clays, along with the types of metabolic and sulfidogenic reactions that might occur in regions of a DGR (e.g., interfaces between the bulk clay and host rock, cracks, fissures, etc.) that fail to attain target parameters necessary to inhibit microbial growth and activity.
Live-streaming: Time-lapse video evidence of novel streamer formation mechanism and varying viscosity

Published: February 2023

Time-lapse videos of growing biofilms were analyzed using a background subtraction method, which removed camouflaging effects from the heterogeneous field of view to reveal evidence of streamer formation from optically dense biofilm segments. In addition, quantitative measurements of biofilm velocity and optical density, combined with mathematical modeling, demonstrated that streamer formation occurred from mature, high-viscosity biofilms. We propose a streamer formation mechanism by sudden partial detachment, as opposed to continuous elongation as observed in other microfluidic studies. Additionally, streamer formation occurred in straight microchannels, as opposed to serpentine or pseudo-porous channels, as previously reported.
Disinfectant, Soap or Probiotic Cleaning? Surface Microbiome Diversity and Bioﬁlm Competitive Exclusion
Authors: Tolmay Janke , Tucker Keira , Wolfaardt Gideon
Published: February 2023

This study extends probiotic cleaning research to a built environment. Through an eight-month cleaning trial, we compared the effect of three cleaning products (disinfectant, plain soap, and a probiotic cleaner containing a patented Bacillus spore consortium), and tap water as the control, on the resident microbiome of three common hospital surfaces (linoleum, ceramic, and stainless steel). Pathogens, Escherichia coli and Staphylococcus aureus, were deposited and desiccated, and competitive exclusion was assessed for each microbiome. Cell survival was shown to be an incomplete tool for measuring microbial competitive exclusion. Biofilm competition offered a fuller understanding of competitive dynamics. A test for culturable cell survival showed that both plain soap and probiotic cleaner regimes established a surface microbiome that outcompeted the two pathogens. A different picture emerged when observing biofilms with a deposited and desiccated GFP-labeled pathogen, Pseudomonas aeruginosa. Competitive exclusion was again demonstrated. On surfaces cleaned with disinfectant the pathogen outcompeted the microbiomes. On surfaces cleaned with plain soap, the microbiomes outcompeted the pathogen. However, on surfaces cleaned with probiotic cleaner, despite the exponentially higher surface microbial loads, the microbiome did not completely outcompete the pathogen. Thus, the standard culturable cell test for survival on a surface confirmed the competitive advantage that is typically reported for probiotic cleaners. However, observation of competition in biofilms showed that the more diverse microbiome (according to alpha and beta indices) established on a surface cleaned with plain soap had a better competitive advantage than the monoculture established by the probiotic cleaner. Therefore, microbial diversity appears to be as critical to the competitive exclusion principle as cell numbers. The study showed that both plain soap and probiotic cleaner fostered competitive exclusion far more effectively than disinfectant. Probiotic cleaners with microbial diversity could be worth considering for hospital cleaning. 
Microbes at Surface-Air Interfaces: The Metabolic Harnessing of Relative Humidity, Surface Hygroscopicity, and Oligotrophy for Resilience

Published: February 2023

The human environment is predominantly not aqueous, and microbes are ubiquitous at the surface-air interfaces with which we interact. Yet microbial studies at surface-air interfaces are largely survival-oriented, whilst microbial metabolism has overwhelmingly been investigated from the perspective of liquid saturation. This study explored microbial survival and metabolism under desiccation, particularly the influence of relative humidity (RH), surface hygroscopicity, and nutrient availability on the interchange between these two phenomena. The combination of a hygroscopic matrix (i.e., clay or 4,000 MW polyethylene glycol) and high RH resulted in persistent measurable microbial metabolism during desiccation. In contrast, no microbial metabolism was detected at (a) hygroscopic interfaces at low RH, and (b) less hygroscopic interfaces (i.e., sand and plastic/glass) at high or low RH. Cell survival was conversely inhibited at high RH and promoted at low RH, irrespective of surface hygroscopicity. Based on this demonstration of metabolic persistence and survival inhibition at high RH, it was proposed that biofilm metabolic rates might inversely influence whole-biofilm resilience, with ‘resilience’ defined in this study as a biofilm’s capacity to recover from desiccation. The concept of whole-biofilm resilience being promoted by oligotrophy was supported in desiccation-tolerant Arthrobacter spp. biofilms, but not in desiccation-sensitive Pseudomonas aeruginosa biofilms. The ability of microbes to interact with surfaces to harness water vapor during desiccation was demonstrated, and potentially to harness oligotrophy (the most ubiquitous natural condition facing microbes) for adaptation to desiccation.

Teniendo en cuenta que la conciencia histórica es uno de los ejes fundamentales de las investigaciones en esta área en los decenios recientes, el presente artículo tiene como objetivo ahondar en algunos de los elementos relativos a la conciencia histórica, así como posibles alternativas que desde el proceso de enseñanza-aprendizaje intencionado podrían contribuir, al menos en cuanto a fundamentos básicos del pensamiento histórico, a su desarrollo en los estudiantes. Con este fin se realizó un análisis de la producción científica sobre el tema teniendo en cuenta relevancia, actualidad y su pertenencia a bases de datos reconocidas. Entre las problemáticas detectadas sobresalen la ausencia de valor en relación con la historia que se concibe como una verdad acabada basada en un conjunto de fechas, datos y acontecimientos que se tienen que aprender; el deficiente uso de conceptos y tiempo histórico, el escaso establecimiento de conexiones pasado-presente-futuro, con énfasis en los dos últimos. Entre las propuestas desarrolladas por especialistas en didáctica de la historia se encuentra la necesidad de implementar un cambio de estrategias que consideren implementar currículos temporales basados en competencias que potencien las conexiones pasado-presente-futuro y permitan interrogar e interpretar las realidades sociales desde una perspectiva histórica y con la ayuda del método histórico; que el estudiantado sea capaz de contrastar las fuentes, comprender el cambio en el tiempo, observar acontecimientos desde el punto de vista de los participantes, matizar a través de pruebas, producir hipótesis y conclusiones teniendo en cuenta los acontecimientos en su propio contexto histórico.

Cmentarzysko w wczesnej epoki żelaza w Świbiu na Górnym Śląsku. Tom 2
Authors: Michnik Monika , Dzięgielewski Karol
Published: February 2023

The cemetery discovered in the village of Świbie, commune of Wielowieś (site 16), District Gliwice, was one of the few large biritual cemeteries with a predominance of inhumation graves belonging to the so-called Gliwice-Częstochowa subgroup of the Lusatian culture. It was only thanks to a grant from the Ministry of Culture and National Heritage in 2021-2022 that a monographic study and publication of the historic materials collected at the Gliwice Museum became possible. The biritual necropolis in Świbie is unique for several reasons. In purely numerical terms, it is the largest cemetery of the Upper Silesian-Małopolska group of the Early Iron Age Lusatian culture (approximately 550 graves), the richest in metal artefacts in this cultural zone (over three thousand bronze and iron artefacts and several dozen lead artefacts), and the most numerous collection of glass and vitreous beads from the Early Iron Age in Poland (over 1,700 specimens). What is striking is the material richness of furnishings in many of the nearly 550 discovered burial complexes, which is unusual for the Upper Silesian-Małopolska cultural zone in the Late Bronze and Early Iron Age and can only be found in the richest necropolises of this period discovered in the Oder zone, such as Domasław, Kietrz or Łazy. What is more important, however, are the possibilities offered by this rich collection with its perfectly documented context for the study of the precise type-chronology of the Hallstatt period north of the Carpathians. The picture of the spatial development of the necropolis, obtained through meticulous chronological studies, makes it possible to formulate conclusions about the pace and extent of cultural change, including the raw material change experienced by the areas of southern Poland at the beginning of the Hallstatt period. The fact of the significant dominance of inhumation over cremation furthermore provides unique opportunities for explaining the purpose and characteristics of certain parts of the costume. The presence of numerous bronzes in many skeletal graves, favouring the preservation of skeletal remains despite adverse environmental conditions, in turn allows the reconstruction of the biological condition and diet of the local population. The size of the necropolis lends credence to the results of the study of the social contacts and wealth differentiation of the community studied. The second volume of the Świbie necropolis monograph is a multidisciplinary study authored by Monika Michnik (Museum in Gliwice) and Karol Dzięgielewski (Institute of Archaeology, Jagiellonian University, Kraków), with contributions from over a dozen authors from many Polish institutions.

The protective effect of aminoguanidine on cerebral ischemic damage in the rat brain
Authors: Danielisová V , Némethová M , Burda J
Published: February 2023

The NADPH-diaphorase (NADPH-d) histochemical technique is commonly used to localize the nitric oxide (NO) produced by the enzyme nitric oxide synthase (NOS) in neural tissue. The expression of inducible nitric oxide synthase (iNOS) is induced in the late stage of cerebral ischemia, and NO produced by iNOS contributes to the delay in recovery from brain neuronal damage. The present study was performed to investigate whether the increase in nitric oxide production via inducible nitric oxide synthase was suppressed by the administration of aminoguanidine, a selective iNOS inhibitor, as it follows a decrease of NADPH-diaphorase activity (a marker for NOS) after four-vessel occlusion used as an ischemic model. The administration of aminoguanidine (100 mg/kg i.p., twice per day up to 3 days immediately after the ischemic insult) reduced the number of NADPH-diaphorase positive cells to control levels. Our results indicated that aminoguanidine suppressed NADPH-diaphorase activity, and also decreased the number of NADPH-diaphorase positive cells in the CA1 region of the hippocampus following ischemic brain injury.
Electrical structure of Gulu geothermal field in Southern Tibet and its implication for the high-temperature geothermal system
Authors: Wan Hanping , Wang Qiao
Published: February 2023

The Yadong-Gulu rift (YGR) South Tibet is a Cenozoic active rift, which is endowed with abundant geothermal resources. The Gulu geothermal field (GGF) is located in the Northern section of the rift, where a large number of high-temperature hot springs develop, but its geothermal system is mysterious. In this study, the three-dimensional (3D) electrical structure of GGF is revealed by broad magnetotelluric (MT) and audio magnetotelluric (AMT). MT reveals that middle and upper crust conductors are developed in the subsurface of GGF. The conductors may originate from the partial melting that drives the geothermal system. AMT reveals that the electrical structure of GGF is conductive alternation cap overlying more resistive reservoir, which is consistent with the classical electrical structure of geothermal systems in worldwide active tectonic zones. According to the geothermal system model, cold fluids may converge from the periphery of GGF to the middle, wherein fault F1 (the Western branch of Jiulazi-Sanxung fault) may be the main channel for cold fluids to migrate downward. The fluids are heated by partial melting in the middle and upper crust, and may migrate upward along fault F2 (the middle branch of Jiulazi-Sanxung fault) and develop into heat reservoirs.

Background

Postoperative nausea and vomiting (PONV) are common after laparoscopic sleeve gastrectomy (LSG), affecting patient satisfaction and postoperative recovery. The purpose of this study was to investigate the incidence and severity of PONV after LSG and the relationship between Helicobacter pylori (HP) and PONV.

Methods

Patients undergoing LSG in our center from June 1, 2018, to May 31, 2022, were divided into HP-positive and HP-negative groups for retrospective analysis. The independent risk factors of PONV were determined by univariate and binary logistic regression analysis using a 1:1 propensity score matching (PSM) method.

Results

A total of 656 patients was enrolled, and 193 pairs of HP-positive and negative groups were matched after PSM. Both groups of patients had similar clinical features and surgical procedures. PONV occurred in 232 patients (60.1%) after LSG, and the incidence of PONV in HP-positive patients was 61.10%. The incidence and severity of PONV were statistically similar in both groups (P=0.815). Multivariate analysis showed that the female sex (OR=1.644, P=0.042), postoperative pain (OR=2.203, P=0.001) and use of postoperative opioid (OR=2.229, P=0.000) were independent risk factors for PONV after LSG, whereas T2DM (OR=0.510, P=0.009) and OSAS (OR=0.545, P=0.008) independently reduced the incidence rate of PONV. There was no difference either in smoking (P=0.255) or alcohol drinking (P=0.801). HP infection did not affect PONV (P=0.678).

Conclusions

The incidence of PONV following LSG was relatively high. Female sex, postoperative pain and use of postoperative opioid predicted a higher incidence of PONV. Patients with T2DM and OSAS were less likely to have PONV. There was no clear association between HP infection and PONV after LSG.
Timeless or tainted? The effects of male ageing on seminal fluid

Reproductive ageing can occur due to the deterioration of both the soma and germline. In males, it has mostly been studied with respect to age-related changes in sperm. However, the somatic component of the ejaculate, seminal fluid, is also essential for maintaining reproductive function. Whilst we know that seminal fluid proteins (SFPs) are required for male reproductive success across diverse taxa, age-related changes in SFP quantity and composition are little understood. Additionally, only few studies have explored the reproductive ageing of the tissues that produce SFPs, and the resulting reproductive outcomes. Here we provide a systematic review of studies addressing how advancing male age affects the production and properties of seminal fluid, in particular SFPs and oxidative stress, highlighting many open questions and generating new hypotheses for further research. We additionally discuss how declines in function of different components of seminal fluid, such as SFPs and antioxidants, could contribute to age-related loss of reproductive ability. Overall, we find evidence that ageing results in increased oxidative stress in seminal fluid and a decrease in the abundance of various SFPs. These results suggest that seminal fluid contributes towards important age-related changes influencing male reproduction. Thus, it is essential to study this mostly ignored component of the ejaculate to understand male reproductive ageing, and its consequences for sexual selection and paternal age effects on offspring.
