Analysis of Mine Change Using 3D Spatial Information Based on Drone Image
Authors: Kim Doo-Pyo , Kim Sung-Bo , Back Ki-Suk
Published: March 2022

Mine development requires continuous management because it causes rapid topographic changes and environmental damage. Drones can be used to produce three-dimensional spatial information by quickly and accurately photographing areas that are difficult or dangerous for humans to approach. In this study, we investigated the possibility of using drone photogrammetry for determining changes and recovery in mines. The accuracy of the drone photogrammetry results was analyzed using checkpoints, and the earthwork volume was calculated and compared with that obtained through a field survey. We determined whether the results were consistent with the mountain recovery plan using drone images. The RMSE was 0.085–0.091 m in the plane and 0.121–0.128 m along the elevation, as determined by analyzing the checkpoint accuracy by creating an orthoimage and a digital surface model based on the drone images; these results satisfy the tolerance range of the 1/1000 digital map descriptions. The drone photogrammetry generated an average error of 11.9% using the conventional measurement method. The possibility of use was proved by confirming the vegetation and rock prevention nets using photographed images. The usability of drone photogrammetry in mines is expected to increase if substantial spatial information is produced and analyzed in the future.

Online Interpersonal Relationships and Data Ownership Awareness Mediate the Relationship between Perceived Benefits and Problematic Internet Shopping
Authors: Duong Xuan-Lam , Liaw Shu-Yi
Published: March 2022

Maladaptive and problematic buying/shopping has been the subject of a considerable amount of research over the last few decades. This research exploited the stimulus–organism–response (S-O-R) theory to evaluate the mediating effects of online interpersonal relationships and data ownership awareness on the relationship between consumers’ perceived benefit of online shopping and problematic internet shopping behavior. A total of 409 internet shoppers participated in this study. The authors performed all the analyses using the statistical package SPSS. The bootstrapping method used parallel and serial mediation models to assess whether OIR and DOA mediate the relationship between PBOS and PIS. The analysis results indicate that PBOS has a negative influence on PIS. In addition, OIR and DOA sequentially and partly mediate the relationship between PBOS and PIS. Pairwise comparisons amongst the three indirect effects suggest that OIR affects the PBOS-PIS relationship more than the other two effects. These results furnish substantial contributions that may advance a coherent theoretical framework on the pathways in which OIR and DOA may influence problematic internet shopping. Limitations of the current study and the implications of these findings are delineated.
Does Strategic Alliance Knowledge Heterogeneity Truly Promote Innovation Performance?
Authors: Sun Yongbo , Sun Ying , Liu Jingyan
Published: March 2022

There is a certain degree of difference in the knowledge and skills of alliance members, and the knowledge heterogeneity among them will have an impact on innovation. The study of the relationship between strategic alliance knowledge heterogeneity (SAKH) and enterprise innovation performance (IP) has important practical significance for enterprise-development strategies. Based on the resource-dependence theory, this study discussed the mediating effect of exploratory learning (EXR) and exploitative learning (EXI) on the impact of SAKH on IP. Using surveys collected from Chinese manufacturing enterprises with strategic alliances, we found that (1) SAKH and IP have an inverted U-shaped relationship; (2) EXR and EXI partially mediate the relationship between SAKH and IP. From the perspective of managers’ attention, this study not only extends the boundaries of knowledge heterogeneity and innovation-related research but also provides a theoretical and practical framework for the promotion and development of alliance enterprise innovation.
Improving Air Quality in Urban Recreational Areas through Smart Traffic Management

Published: March 2022

Green parks are the only natural places for recreation in many metropolitan areas, and the European Commission is seeking to improve their air quality and, consequently, citizens’ physical and mental health. One of the recently adopted approaches is to achieve pollution abatement in these green areas by reducing nearby traffic. In this paper, we analyze the impact of reducing the traffic in nearby streets to avoid pollution by proposing two different approaches. Our goal is to improve the pollution levels in Valencia’s most significant green areas by limiting vehicular traffic flow in nearby streets. To this end, we consider two alternative solutions—a more restrictive one and a less restrictive approach—in an attempt to achieve a tradeoff between emission control and congestion avoidance. Moreover, we show how our proposal can reroute traffic throughout the city without having traffic jam problems associated with the proposed approaches. In addition, we determine how the traffic flow data and the emissions in the city vary due to the traffic restrictions that we enforce. The experimental results show that it is possible to achieve improvements in terms of pollution with both of our restriction approaches; in particular, with the partial traffic isolation model, the pollution rates in the target area decreased by 17%, which we consider an excellent initial result for the applicability and effectiveness of these methods when an adequate traffic routing system is adopted.
Non-Financial Benefits of Corporate Social Responsibility to Saudi Companies
Authors: Allui Alawiya , Pinto Luisa
Published: March 2022

In Saudi Arabia, as in the international arena, corporate social responsibility (CSR) is a trending phenomenon that has been transforming and influencing government policies, business strategic management, and societal relationships. This study aims to identify the non-financial benefits of CSR and the general CSR approach in Saudi Arabia. A survey was conducted among randomly selected Saudi companies from the manufacturing and service sectors. Descriptive statistics on company profiles, CSR approaches, and CSR benefits were analyzed. The findings demonstrated that the most prevalent CSR approach is to minimize the negative impacts and maximize the positive impacts of the business, considering the social, environmental, and economic aspects. The non-financial benefits from CSR activities include attracting and retaining employees, improving brand reputation, and enhancing innovation. The main limitations of this study involve the relatively small sample size and the lack of longitudinal data to analyze the effects of the variables over time. The study findings not only provide deeper insights into CSR approaches and non-financial benefits but could also encourage firms’ managers and stakeholders to improve CSR activities to better achieve non-financial benefits and improve competitive advantage.

Published: March 2022

Green Lean Six Sigma has emerged in the Industry 4.0 era as a business strategy contributing to the circular economy by adopting the 3R concept, i.e., reduce, reuse, and recycle. Despite its broadly acknowledged capabilities in the manufacturing industry, practitioners continue to be cautious about its implementation, owing to insufficient knowledge and culture. Hence, there is a need to systematize the existing knowledge regarding this green initiative and also to recognize the key factors enabling its implementation. In the Malaysian manufacturing context, the enabling factors have yet to be identified and evaluated. This current study is the first of its kind to identify and examine these factors and to create a structural model to conceptualize and operationalize this business strategy. The implemented methodological approach includes two steps. Firstly, it performs a systematic review of leading studies on the topic, which are rather scarce in the current context. The second step entails a principal component factor analysis using varimax rotation to finalize the findings. The theoretical and empirical results revealed a structural model with five interconnected key factors, including twenty-seven enablers, that can be used to narrow the existing knowledge gap in the understudied context.

Published: March 2022

Crop diversity contributes to yield stability and nutrition security and is valued for its potential use in breeding improved varieties and adaptation to future climates. Women across the globe contribute to biodiversity conservation, and, in the Central Andes region, the cradle of potato diversity, rural women play a vital role in the management of a wealth of native potato diversity. To examine how gender roles and traditions influence the agricultural and conservation practices of male and female custodians of native potato diversity, we undertook a qualitative study in eight farming communities high in the Andes, in the Pasco region of Peru. This article reviews agricultural and crop diversity management practices, farmer motivations for conserving potato diversity, the role that agrobiodiversity plays in family diets and economies, and support of in situ conservation by external actors. It examines how gender norms limit the potential of women to fully benefit from the crop and argues for more gender-responsive approaches that empower both women and men, enable women to overcome barriers, and contribute to a more inclusive, community-based management of agrobiodiversity that ensures its long-term conservation and contribution to community development and well-being.
Climate Change Perceptions, Impacts and Adaptation Strategies: Insights of Fishers in Zambezi River Basin, Zimbabwe
Authors: Muringai Rodney Tatenda , Mafongoya Paramu , Lottering Romano Trent
Published: March 2022

The Zambezi River Basin is considered to be highly vulnerable to the impacts of climate change and adverse weather events, which might cause serious environmental, economic, and social consequences for millions of people. Therefore, it is crucial to understand how natural resource-dependent people perceive climate change, and how they adapt to the changes, as it is very important for climate change adaptation policy formulation and its implementation. Therefore, this study seeks to assess fishers perceptions of climate change, its impacts on fishery resources and livelihoods, and their adaptation strategies. Data were collected from 120 fishers in two basins (Binga and Kariba) along the shores of Lake Kariba using a mixed-method research approach. Meteorological data were obtained from the Meteorological Department Services of Zimbabwe (MSDZ). The findings show that fishers of Lake Kariba have observed changes in temperature and rainfall trends. Fishers believe that the perceived changes of the climatic variables have led to a decline in fish productivity and fish catches. To cope with declining fish stocks and catches, fishers have adopted several adaptation strategies, including changing fishing gear, targeting new fish species, and increasing fishing efforts. These study findings help to set a path towards local specific climate change adaptation strategies for small-scale fishers. This study provided relevant information for policy makers and fisheries stewards to formulate appropriate policies and programmes aimed at enhancing fishers adaptation to climate change and promote sustainable fisheries.
Optimising the Cost of Reducing the CO2 Emissions in Sustainable Energy and Climate Action Plans
Authors: Matak Nikola , Mimica Marko , Krajačić Goran
Published: March 2022

Tackling climate change can be achieved through local and regional initiatives, such as the Covenant of Mayors, which create energy and climate plans with mitigation measures. Upon the development of energy plans, the mitigation of greenhouse gas emissions (GHG) can be achieved through an individual or joint approach. The research aims to upgrade methods for local and regional energy planning through the choice of mitigation actions and alternative scenarios for the reduction of GHG emissions. This is achieved through optimisation of the selection of mitigation measures in the case of the wider Dubrovnik area in Croatia by choosing the most suitable option for implementation when comparing individual and joint approaches for the planning of the measures. Moreover, the implementation of single and sets of mitigation measures is compared through the total cost abatement curve. The modelled problem represents a non-linear problem as exponential functions and multiplication of variables occurs in the modelled equations. Visualisation of the results is achieved via the total cost abatement curve which ranks measures from the most cost-effective to the least cost-effective. It is shown that with the use of optimisation models, it is possible to find such sets of measures and alternative scenarios, which will, with less financial means, reach a minimal reduction of CO2 emissions by 40% in local and regional energy systems and result in financial savings of three times in the analysed case. In this way, it could be possible to increase the overall implementation of SECAP measures and mitigate the problem of the lack of appropriate financial planning.

Published: March 2022

In 1999, for (0≤k<∞), the concept of conic domain by defining k-uniform convex functions were introduced by Kanas and Wisniowska and then in 2000, they defined related k-starlike functions denoted by k−UCV and k−ST respectively. Motivated by their studies, in our work, we define the class of k-parabolic starlike functions, denoted k−SHm,q, by using quasi-subordination for m-fold symmetric analytic functions, making use of conic domain Ωk. We determine the coefficient bounds and estimate Fekete–Szegö functional by the help of m-th root transform and quasi subordination for functions belonging the class k−SHm,q.

Published: March 2022

Previous studies have described the chemical pollution in indoor air of healthcare and care facilities. From these studies, the main objective of this work was to conduct a quantitative health risk assessment of the chronic inhalation of chemical compounds by workers in healthcare and elderly care facilities (hospitals, dental and general practitioner offices, pharmacies and nursing homes). The molecules of interest were 36 volatile and 13 semi-volatile organic compounds. Several professional exposure scenarios were developed in these facilities. The likelihood and severity of side effects that could occur were assessed by calculating the hazard quotient for deterministic effects, and the excess lifetime cancer risk for stochastic effects. No hazard quotient was greater than 1. Three compounds had a hazard quotient above 0.1: 2-ethyl-1-hexanol in dental and general practitioner offices, ethylbenzene and acetone in dental offices. Only formaldehyde presented an excess lifetime cancer risk greater than 1 × 10−5 in dental and general practitioner offices (maximum value of 3.8 × 10−5 for general practitioners). The health risk for chronic inhalation of most compounds investigated did not appear to be of concern. Some values tend to approach the acceptability thresholds justifying a reflection on the implementation of corrective actions such as the installation of ventilation systems.

Published: March 2022

Deoxynivalenol (DON), a mycotoxin produced by Fusarium graminearum, is one of the most prevalent contaminants in livestock feed and causes very large losses to animal husbandry every year. Taraxasterol, isolated from Taraxacum officinale, has anti-inflammatory, antioxidative stress, and antitumor effects. In the present study, bovine mammary epithelial cells (MAC-T) were used as a model, and different concentrations of taraxasterol (0, 1, 5, 10, and 20 μg/mL) were used to protect against DON-induced cell damage. The results showed that taraxasterol at a concentration of 10 μg/mL significantly increased cell viability. Analysis of lactate dehydrogenase (LDH) levels indicated that taraxasterol substantially decreased LDH release caused by DON. Taraxasterol effectively alleviated the depletion of glutathione (GSH), the increase in the lipid peroxidation of malondialdehyde (MDA), the reduction in total superoxide dismutase (T-SOD) activity, and the decrease in total antioxidant capacity (T-AOC) induced by DON. The results further showed that taraxasterol reduced the accumulation of reactive oxygen species (ROS). Taraxasterol was found to relieve endoplasmic reticulum (ER) stress by suppressing the expression of glucose-regulated protein 78 kDa (GRP78), activating transcription factor 6 (ATF6), activating transcription factor 4 (ATF4) and the transcription factor C/EBP homologous protein (CHOP), and reducing cell apoptosis by suppressing the expression of caspase-3 and Bcl2-associated X (BAX) and upregulating the expression of the antiapoptotic protein B-cell lymphoma-2 (Bcl-2). Our research results indicate that taraxasterol could alleviate DON-induced damage to MAC-T cells.
Gene-Edited Cell Models to Study Chronic Wasting Disease

Published: March 2022

Prion diseases are fatal infectious neurodegenerative disorders affecting both humans and animals. They are caused by the misfolded isoform of the cellular prion protein (PrPC), PrPSc, and currently no options exist to prevent or cure prion diseases. Chronic wasting disease (CWD) in deer, elk and other cervids is considered the most contagious prion disease, with extensive shedding of infectivity into the environment. Cell culture models provide a versatile platform for convenient quantification of prions, for studying the molecular and cellular biology of prions, and for performing high-throughput screening of potential therapeutic compounds. Unfortunately, only a very limited number of cell lines are available that facilitate robust and persistent propagation of CWD prions. Gene-editing using programmable nucleases (e.g., CRISPR-Cas9 (CC9)) has proven to be a valuable tool for high precision site-specific gene modification, including gene deletion, insertion, and replacement. CC9-based gene editing was used recently for replacing the PrP gene in mouse and cell culture models, as efficient prion propagation usually requires matching sequence homology between infecting prions and prion protein in the recipient host. As expected, such gene-editing proved to be useful for developing CWD models. Several transgenic mouse models were available that propagate CWD prions effectively, however, mostly fail to reproduce CWD pathogenesis as found in the cervid host, including CWD prion shedding. This is different for the few currently available knock-in mouse models that seem to do so. In this review, we discuss the available in vitro and in vivo models of CWD, and the impact of gene-editing strategies.
Immune Response to SARS-CoV-2 Vaccine and Following Breakthrough Omicron Infection in an Autoimmune Patient with Hashimoto’s Thyroiditis, Pernicious Anemia, and Chronic Atrophic Autoimmune Gastritis: A Case Report
Authors: Cluff Emily , Bellusci Lorenza , Golding Hana , Khurana Surender
Published: March 2022

In healthy adults, hybrid immunity induced by prior SARS-CoV-2 infection followed by two doses of mRNA vaccination provide protection against symptomatic SARS-CoV-2 infection. However, the role of hybrid immunity in autoimmune patients against Omicron is not well documented. Here, we report a young autoimmune patient with prior infection and two doses of mRNA-1273 vaccination who was exposed to Omicron and developed a symptomatic disease. Prior to Omicron infection, the patient had strong neutralizing antibody titers against the vaccine strain, but no neutralization of Omicron. Post Omicron infection, high neutralizing titers against Omicron were observed. Furthermore, enhanced neutralizing antibody titers against other variants of concern—Alpha, Beta, Gamma, and Delta—were observed, suggesting an expansion of cross-reactive memory B-cell response by the SARS-CoV-2 Omicron infection. Autoimmune patients may require careful monitoring of immune function over time to optimize booster vaccine administration.
Environmental Factors Drive Periphytic Algal Community Assembly in the Largest Long-Distance Water Diversion Channel

Published: March 2022

Periphytic algae exist widely in different waters. However, little is known about periphytic algae in long-distance water diversion channels across watersheds. We investigated the periphytic algae and the environmental factors at twenty sampling sites in the middle route of the South-to-North Water Diversion Project (MRP). The dominant species were Desmodesmus intermedius (Hegewald), Calothrix thermalis (Bornet & Flahault), Calothrix parietina (Bornet & Flahault) and Leptolyngbya benthonica (Anagnostidis) (dominance > 0.02) as measured in a whole year. Habitat heterogeneity in the MRP led to lower spatial heterogeneity and higher temporal heterogeneity of the periphytic algal community. Stochastic processes are the major process in periphytic community assembly. In deterministic processes, homogeneous selection had the major role in structuring the periphytic community, whereas the role of heterogeneous selection was less significant. In stochastic processes, dispersal limitations had the major role in structuring the periphytic community, whereas the role of homogenizing dispersal and drift were less significant. The variation in total nitrogen and total phosphorus promoted more stochastic processes (−1.96 < βNTI < 1.96). The variations in water temperature and water velocity promoted more heterogeneous selection (βNTI > 1.96). In integrating all of this empirical evidence, we explore the role of environmental factors in the action of ecological processes shaping thecommunity assembly of the periphytic algal community.

Water-powered facilities (WPFs) have traditionally been a pillar of the economy and social development. Therefore, the state took an interest in having these objects recorded and mapped in relevant maps and registers. This article focuses on identifying and localizing WPFs in the Moravice River basin in the so-called Sudetenland, Czechia, between the years 1763 and 2021. Specifically, the evolution and (dis)continuity of the WPFs are assessed through an analysis of cartographic and archival sources, reflecting the wider socioeconomic and demographic context as explanatory variables. The cartographic sources included old military topographic maps of Austria-Hungary and Czechoslovakia from four periods (the mid-18th century, mid-19th century, end of the 19th century, and mid-20th century) on the one hand and two state water-powered facility registers from 1930 and 1953 on the other. The archival sources included funds from regional and state archives. The results show that the count of WPFs peaked during the 19th century, after which there occurred a steep decline caused by societal and economic changes, namely, the expulsion of the local German population, nationalization in the postwar period, and economic and organizational transformations in the socialist era. Special attention is paid to hydropower plants, whose evolution reflects the outlined economic processes.

In order to guarantee the sustainability of the potable water supply service, a water utility must generate improvements in its performance in an integrated manner. The objective of this research is to analyze and provide information about the components and indicators used by the water utility of Leon, Guanajuato, Mexico, which directly impact water management. The Analytic Hierarchy Process (AHP) and Fuzzy Logic (FL) methodologies were applied. The study determined the trends and evolution over time from 2002 to 2017. From the combination of both methodologies, a Water Supply Management Index was obtained with an average value of 0.79, which shows positive progress for water resource management by the water utility. However, the traditional indicators are insufficient and require particular attention. The analysis helped to identify those indicators that do impact water management and their ability to measure the sustainability of the city’s water utility. This may make it possible to monitor the progress toward the accomplishment of Sustainable Development Goal 6 (SDG 6), by performing an evaluation and thorough analysis of the status of water resources.

The assessment of groundwater irrigation using robust tools is essential for the sustenance of the agro-environment in arid and semi-arid regions. This study presents a reliable method consisting of a combination of multivariate analysis and geostatistical modeling to assess groundwater irrigation resources in the Western Middle Cheliff (Algeria). For this goal, mean data from 87 wells collected during April to July 2017 were used. The hierarchical cluster analysis (HCA) using the Q-mode approach revealed three distinct water types, with mineralization increasing from cluster 1 to cluster 3. The Principal Component Analysis (PCA) utilizing the Varimax method approach allowed the extraction of three main components: the first and second (PC1, PC2), revealing that the geogenic process, have influenced the hydrogeochemical composition of groundwater. The pollution induced by agriculture activities has been related to PC3. Based on the combination of multivariate analysis and geostatistical modeling, the distribution maps were created by interpolating the factor distribution values acquired in the study region using the ordinary kriging (OK) interpolation method. The findings revealed that both natural processes and man-made activities have a substantial impact on the quality of groundwater irrigation. Cluster mapping, another often used combining approach, has shown its effectiveness in assisting groundwater resource management.

Published: March 2022

One in three Haitian women, and two in three Haitian children, experience physical abuse. This study aims to assess characteristics of abused Haitian women and identify effective sources of support. This cross-sectional study used multiple logistic regression models to analyze sociodemographic characteristics of Haitian women, associations with abuse-exposure from a parent/intimate partner (IPV)/any perpetrator, and impacts of seeking help for abuse, from police/doctors/family. About 9.1% experienced abuse by a parent, 8.6% from IPV. Women abused by a parent were less likely to be employed (OR = 0.74, [95% CI = 0.59–0.93]) and more likely to have an often-drunk partner (2.10, [1.54–2.87]). IPV-exposed women were more likely to have primary education (1.56, [1.12–2.16]), an often-drunk partner (3.07, [2.24–4.22]) and less likely to live rurally (0.65, [0.47–0.89]). Seeking help from own family for IPV exposure was strongly associated with having a job (2.00, [1.04–3.89]) (P for interaction = 0.039) and seeking help from partner’s family for IPV was strongly associated with having an often-drunk husband (8.80, [3.07–25.23]) (p for interaction <0.001). We recommend family-based interventions targeting men’s perceptions about abuse and their alcohol consumption, introducing programs/policies integrating women into the workforce, and havens for abuse victims to confidentially receive individualized support.
BAUDRILLARD Y EL VACÍO DE LAS ARTES

Published: March 2022

Este trabajo retoma el planteamiento de Jean Baudrillard para diagnosticar, entretejiendo la exposición de las ideas de este pensador francés con las consecuencias derivadas, la pérdida del carácter simbólico en el arte. Se ha encontrado en él una propuesta que intenta dar cuenta de la cultura reciente y de las artes en este sentido. Aunque se tienen en cuenta los estudios sobre la imagen, el arte y el simulacro de Adolfo Vázquez Rocca sobre Baudrillard, se desglosan las precisiones conceptuales de la teoría, siguiendo las contraseñas de Baudrillard, lo que dice de la situación de las artes y la pérdida de su carácter simbólico. Ante esta situación se abren preguntas para exploraciones siguientes: ¿por qué y para qué retornar al símbolo y a lo oculto si ya impera lo transparente?, ¿qué consecuencias tiene no dejar nada oculto en la sociedad y la cultura?, ¿es cierto que todo es obsceno y fascinante?, ¿tiene solución la enfermedad? Las respuestas a estas cuestiones no se encontrarán en Baudrillard y, según se ve, tampoco una cura.

BAUDRILLARD AND THE VACUUM OF THE ARTS

ABSTRACT

This paper takes up the approach of Jean Baudrillard to diagnose, interweaving the exposition of the ideas of this French thinker with the derived consequences, the loss of symbolic character in art. It has found in him a proposal that tries to give account of the recent culture and the arts in this sense. Although the studies on the image, the art and the simulation of Adolfo Vázquez Rocca on Baudrillard are taken into account, the conceptual precisions of the theory are broken down, following the passwords of Baudrillard, what it says of the situation of the arts and the loss of its symbolic character. Faced with this situation open questions for subsequent explorations: why and why return to the symbol and the hidden if the transparent already prevails? What are the consequences of not leaving anything hidden in society and culture? Is it true that everything Is it obscene and fascinating? Does the disease have a solution? The answers to these questions will not be found in Baudrillard and, as you can see, neither will a cure.

THEORETICAL RECOMMENDATIONS FOR CHOOSING THE WALL THICKNESS OF A LIP SEAL OPERATING WITHOUT LUBRICATION
Authors: Busarov S. , Roman R. , Sinicin N.
Published: March 2022

As the literature review has shown, at this point in time, there are almost completely no recommendations for choosing the wall thickness of a cuff L-shaped seal operating mainly in dry friction conditions. The service life of the entire compressor unit will depend on the correct choice of the wall thickness of the seal. In this paper, recommendations for the design of a sleeve cylinder piston seal are considered. The basic calculation formulas for choosing the minimum wall thickness are presented, and the boundary conditions for choosing the maximum wall thickness are also presented. On the basis of ANSYS package programs, verification calculations of the calculated wall thicknesses were carried out at various pressures in the working chamber at an average temperature of plus 55 ° C. The pressure in the working chamber varied from 0.8 MPa to 3.5 MPa. In the course of the study, it was found that the maximum wall thickness of the seal should not exceed Smax = 3.7 mm, since a further increase in wall thickness will lead to an excess of permissible tensile stresses and reduce the elastic properties of the material. For the convenience of the user, in the Visual Basic for Applications (VBA) software environment, a calculator was developed for the rapid design of the geometry of the piston lip seal.

Published: March 2022

On the example of LLC "Agroindustrial Complex "Promagro", a list of biological preparations used in the Belgorod region to reduce unpleasant odors from manure effluents has been compiled. In this work, measurements of the content of harmful substances and the level of odors in pig fattening workshops and on the emission of ventilation shafts of pig-breeding complex buildings were carried out: concentrations of carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NO2), sulfur oxide (SO2), methane (CH4), hydrogen sulfide (H2S) and ammonia (NH3), as well as the level of odors in the territories adjacent to the pig complex. The calculation of the dispersion of emissions of harmful and odorous substances in the territories (GOST R 58578-2019 Rules for the establishment of standards and control of emissions into the atmosphere) showed the need to introduce odor destructors into the manure intake baths. In the Belgorod region, the following biological destructors are used at various pig breeding complexes: "Embionic" "Bactofor-3", "Sanvit-K", "Sanvit-K-forte", "Doctor Robik LGN 050", "UBP Bius", "Ecomik Pro V". Among the enterprises actively using "Baktofor-3" is LLC "APK "Promagro", defined as the base. A comparative characteristic of the effectiveness of the drugs was carried out, the optimal concentrations of drugs for the introduction of manure into the baths were determined.

Published: March 2022

The primary task of our work is to determine the distribution and functioning of healthcare facilities in the planning structure of large cities in domestic and foreign practice. Domestic experience is present in cities which are characterized by introducing reforms in the health system: Moscow, St. Petersburg, Kazan, Tomsk, Perm. We studied the features of the distribution of healthcare facilities in cities which are characterized by an active policy of reforming the health care system: Singapore, Hong Kong, Great Britain, Germany, Israel. The research have been conducted on the basis of general scientific methods: analysis, synthesis and systematization of data identified from literary, graphic and Internet resources. As a result of analysis the spatial placement of the components the healthcare facilities we have been compiled the heat maps, which demonstrating the features of placement in the planning structure of cities. We have been analyzing a land plots of healthcare facilities to identify the compliance to the current regulatory documents and to determine the density of development depending on the location in the structure of the city.

Purpose: to give a comparative description of the peculiarities of motor activity of boxers-veterans of different styles of fighting based on the analysis of psychophysiological and biomechanical parameters.
Material and Methods: The study involved 42 qualified veteran boxers (age 45-50 years, body length - 178.67±8.26 cm, body weight - 70.96±9.38 kg). The biomechanical indicators of a direct blow in boxing were recorded using the Kinovea program, version 0.8.15, and psychophysiological indicators using the Psychodiagnostics program. As biomechanical indicators, the speed of movement of various points of the limbs and the angles in the joints were determined. As psychophysiological indicators, the speed of a simple visual-motor reaction, a reaction of choice in various testing modes was recorded. Based on these indicators, the mobility and endurance of the nervous system were determined. The reliability of differences between groups of different fighting styles was determined.
Results. Tempo-style boxers differ from representatives of other fighting styles in their lower mobility of the nervous system and greater endurance for speedy and precise actions. Tempo-style boxers have the lowest values ​​of the angle in the knee joint throughout the movement (p<0.05, p<0.01) and the highest speed of movement. Play style boxers are characterized by the greatest angle in the shoulder joint at the very beginning of the movement (p<0.05, p<0.001), the highest speed of fist and shoulder movement at the very beginning of the movement (p<0.001). Power style boxers develop maximum movement speed at the end of a straight punch compared to the beginning. Power style boxers are distinguished by the smallest values ​​of the angle in the elbow joint, which is especially noticeable at the end of the movement (p<0.001).
Conclusions. Psychophysiological features of boxers of different styles of fighting are reflected in the features of the technique of a direct blow. The lack of speed when tempo-style boxers are engaged in movement is supplemented and compensated by the high speed of movement. Play style boxers are characterized by high speed of movement at the very beginning of punching. Power style boxers are distinguished by the gradual development of movement speed.

Purpose: In today's sport, and especially in high-performance sports where volleyball also belongs, continuous monitoring of Body Composition (BC) can significantly regulate the training process, which has a positive effect on the top form of athletes. Aim of the current study was to assess and analyze the body composition of a female volleyball players VC "Jahorina", by Bioelectric Impedance Analysis (BIA). Material and methods: In study the participants consist 18 female volleyball players, the members of the  Volleyball Club ''Jahorina'' from Pale, East Sarajevo City (Body height = 173 ± 8.77 cm; Body weight = 66.04 ± 9.09kg; BMI = 22.03 ± 2.19 kg/m², decimal age 19.11 ± 2.63 years old) who competes in the Premier League of Bosnia and Herzegovina (B&H). Results: of the study showed that the body composition is within the healthy (allowed) values recommended for this population of volleyball players (Body Fat = 24.82%; Body Fat=11.44kg; Body Water = 53.68%; Body Muscle = 47.09 kg, BMR = 1538.08; DCI = 6435.38, etc.). Conclusion: Compared to the results of other authors, that Jahorina volleyball players do not lag far behind European clubs in terms of weaker BC (BF%, BFkg, BW%, BMkg, BMR, DCI, BMI, etc.). The only place where they are inferior is the body height of the volleyball player (height = 173 ± 8.77 cm), while the relative value of Body weight = 66.04 ± 9.09 kg is evident.

Background: The cost of health care is a large part of every household’s budget. On the other hand, as an economic entity, the hospital is constantly faced with different aspects of cost and revenue. So, we are dealing with conflicting objectives. Objectives: The main purpose of the research is to help financial management in a specialty hospital. This article provides part of operational research under bi-level optimization for hospital managers to provide targeted financial planning. The method is based on the fact that the objective is to maximize the hospital income on one level, and on the other level, the objective is to reduce the patient’s payment. Methods: The hierarchical and decentralized optimization problem is written as a bi-level model that minimizes patient costs and maximizes hospital revenues, which is an NP-Hard problem. The optimal solution to this problem is obtained using a genetic algorithm. Then, the hospital’s performance is evaluated by the Pabon Lasso diagram. It is shown that the use of this model has a significant effect on the hospital’s performance. Results: Implementation of this model in the studied hospital shows that patient payment costs decreased and hospital income increased (reaching equilibrium point). Conclusion: Hospital performance after model implementation was evaluated by the Pabon Lasso diagram and showed that it has an effective role in hospital performance.
