Published: July 2022

The growing popularity of wearable physical activity (PA) monitors and fitness applications (apps) in recent years and the vast amounts of data that they generate present attractive possibilities for surveillance. However, measurement accuracy is indispensable when tracking PA variables to provide meaningful measures of PA. The purpose of this study was to examine the criterion validity of wearable PA monitors and a combination of GPS and accelerometer free of charge smartphone apps, during self-paced outdoor walking and running. Thirty-eight healthy adolescents (15.3±2.0 years) participated in this cross-sectional study. They were fitted with Garmin Forerunner 310XT, Garmin Vivofit, Medisana Vifit, and smartphones running the Runkeeper, Runtastic, Sports Tracker (GPS), Pedometer, Accupedo, Pedometer and Pedometer 2.0 (accelerometer) apps. They were asked to walk and run 1.22 km for each trial and two researchers counted every step taken during trials with a digital tally counter. Validity was evaluated by comparing each device with the criterion measure using Repeated measures analysis of variance (ANOVA), Mean Absolute Percentage Errors (MAPE) and Bland-Altman plots. MAPE were low for Forerunner and GPS apps for distance in both conditions (2.27%- 9.73%), and significantly higher for the accelerometer monitors and apps (6.92%-39.02%). Vivofit (MAPE=6.51%) and Vifit (MAPE=6.66%) accurately estimated the number of steps during walking, however only Vivofit (MAPE=3.95%) was accurate during running. All accelerometer-based apps had high MAPE for step counting (9.87%-40.26%). The findings suggested that GPS monitors and apps were accurate tools for counting distance during walking and running, while accelerometer- based monitors and apps had higher errors. Vivofit provided accurate estimates of step count in both conditions, and Medisana Vifit was valid during walking. Accupedo was the only app with an acceptable step count error.

In basketball high intensity jumping and sprinting performance is of high importance. There seems to be a relationship between maximal strength (MSt) and jumping performance in general, but influence of MSt in the plantar flexors and jumping performance seems not to be investigated very well. Thus, the aim of this study was to investigate the influence of MSt in the plantar flexors on jumping performance. 37 young elite basketball players were included (age: 13.9±1.8 years; weight: 66.4±16.8 kg; height: 179.21±13.24 cm) and countermovement jump (CMJ) and squat jump (SJ) height as well as unilateral and bilateral maximal isometric contraction in the plantar flexors with bended knee joint were assessed. Pearson correlations were calculated for MSt and jumping performance and Bland-Altman Analysis was performed to determine the level of variance between bilateral MSt assessment and cumulated MSt value of unilateral measurements. This study shows a moderate influence of isometric MSt in the calf muscle on jumping performance, so it seems beneficial to include the training of the plantar flexors in the training routine of basketball players. When determining MSt, the bilateral force deficit must be considered, even though there was no influence on determined correlations.
Three Dimensional Fuzzy Reliability for System Performance Evaluation
Authors: Abed Kadhum Ahmed
Published: July 2022

The research proposed a developed methodology for evaluation the system performance in uncertainty associated with traditional modelling methodology is focused on either load L or resistance R variability, but not both. A two-dimensional (2D) fuzzy set (traditional model), represent with the one dimension for universe of discourse (in x-direction) and the second dimension of his membership degree (in y-direction), is not full sufficient to handle both, load and resistance variation of system performance. The theoretical principle basis of this research is based on development of the three dimensional (3D) of fuzzy set that includes system performance variability in load and resistance from two dimensional. The proposed methodology (traditional model) extends the acceptance level of partial performance of system concept to a 3D-dimantion representation. This representation allows to capturing the changing of preferences of decision makers in load and resistance. The major objective of the research is to proposed the original methodology for evaluate system performance and management that is capable of; (a) addressing uncertainty caused by load and resistance variability and ambiguity; (b) integrating objective and subjective evaluation; and (c) assisting system performance management decision making based on a more detailed certainty evaluation of load and resistance variability.
The study proposed two models for fuzzy reliability performance indexes: first traditional model included (I) 2D fuzzy reliability-vulnerability Rv index, (II) 2D fuzzy robustness Ro index; the second developed model (i) 3D fuzzy reliability-vulnerability Rv index, (ii)  3D fuzzy robustness Ro index; and comparing between them. These indexes have the capability of evaluating the operational performance of complex systems. Proposed methodology is illustrated by using the Al-Wathba Water Supply System (WWSS) as a case study.

Authors: Kurniawan Ilham , Zahra Hafizh
Published: July 2022

Tannins are one of the main compounds in plants with potential health benefits. Gallotannin is one of the biologically active tannins groups produced by some medicinal plants. Gallotannins is a hydrolyzable tannin compound biosynthesized through gallic acid, shikimic acid, and pentagalloylglucose pathways. Gallotannins can be separated by cascade solvent extraction procedures, column chromatography, and preparative HPLC. This review focuses on the discussion of biosynthesis and structure-activity relationship of tannins as antibacterial and anti-inflammatory. The structure-activity relationship (SAR) and biological activity of gallotannins is caused by the molecular bonds between gallotannins and certain other compounds, especially proteins, which make complex compounds, change physiological and morphological processes in bacterial cells or tissues. The biological activities of gallotannin include anti-inflammatory, anticancer or antitumour, antiviral, antioxidant, antibacterial, and antidiabetic. This review used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method approach in a short, concise, and clear summary about tannins through various references.

Authors: Mijwil Maad , Salman Shukur Ban
Published: July 2022

Heart diseases are diverse, common, and dangerous diseases that affect the heart's function. They appear as a result of genetic factors or unhealthy practices. Furthermore, they are the leading cause of mortalities in the world. Cardiovascular diseases seriously concern the health and activity of the heart by narrowing the arteries and reducing the amount of blood received by the heart, which leads to high blood pressure and high cholesterol. In addition, healthcare workers and physicians need intelligent technologies that help them analyze and predict based on patients’ data for early detection of heart diseases to find the appropriate treatment for them because these diseases appear on the patient without pain or noticeable symptoms, which leads to severe concerns such as heart failure and stroke and kidney failure. In this regard, the authors highlight an amount of literature considered the most practical in utilizing machine learning techniques in predicting heart disease. Twenty articles were chosen out of fifty articles gathered and summarised in a table form. The main goal is to make this article a reference that can be utilized in the future to assist healthcare workers in studying these techniques with ease and saving time and effort on them. This article has concluded that machine learning techniques have a significant and influential role in analyzing disease data, predicting heart disease, and assisting decision-making. In addition, these techniques can analyze data that reaches millions of cohorts.

A novel technique Sumudu transform Adomian decomposition method (STADM), is employed to handle some kinds of nonlinear time-fractional equations. We demonstrate that this method finds the solution without discretization or restrictive assumptions. This method is efficient, simple to implement, and produces good results. The fractional derivative is described in the Caputo sense. The solutions are obtained using STADM, and the results show that the suggested technique is valid and applicable and provides a more refined convergent series solution. The MATLAB software carried out all the computations and graphics. Moreover, a graphical representation was made for the solution of some examples. For integer and fractional order problems, solution graphs are shown. The results confirmed that the accuracy of this technique converges to the integer order of the issues.

Formulation of the problem. The basis of modern energy − various types of power plants, of which thermal power plants is about 40 %. The technology of electricity production at thermal power plants is harmful due to the generation of large amounts of waste. They account for more than 30 % of emissions of harmful substances from the total emissions of industrial enterprises. Increased demand for electricity causes an increase in their production, which leads to an increase in the amount of ash and slag waste and emissions of harmful substances into the atmosphere. The purpose of the article . In Ukraine, 160 thousand hectares out of 60 million hectares of total area are dumps of industrial waste, or as they are called by-products. About 8 million tons of ash and slag waste are generated in Ukraine every year, and their storage is accompanied by a number of extremely negative consequences for the environment and human health. With ash and slag   dumps containing toxic elements polluting the ground water and underwater, require exclusion of large areas. The volume of already accumulated waste reaches more than 300 million tons and occupies huge areas of land. At the same time, almost all ash and slag dumps of Ukrainian coal-fired and thermal power plants are almost full, so more and more areas are needed to continue the work. Analysis of recent research and publications. According to European researchers, this type of waste disposal costs about 60 euros/ton. The average thermal power plant spends about 12…36 million euros a year just for the maintenance of ash dumps.

Authors: VOROBIOV V. V. , SHYLO O. S.
Published: July 2022

Problem statement. As a result of the Russian attack on Ukraine, which began on February 24, 2022, the construction of many cities in Ukraine regions was seriously destroyed. Fleeing the war, between five and seven million (according to various estimates by foreign experts) Ukrainian civilians have to temporarily evacuate to EU countries and other region of the world. Part of the population from the eastern regions of the country moved to Western Ukraine. Many people have forever lost their former housing, which is completely destroyed. Unfortunately, the destruction of cities by the Russian troops continues. It is impossible to conduct definitive state monitoring of the buildings and structures in order to understand the needs indicators for housing and public buildings in the existing conditions. Now it is impossible to count reliably the number of citizens who are able to return to their cities. This means that the map of population distribution and its density on the territory of Ukraine in the near future will be significantly different from the indicators that existed before February 24, 2022. However, the problem of rebuilding cities needs to be considered now. This raises the issue of balancing the architectural and stylistic mix of the surviving buildings with the new constructions that will appear after the Victory. This is the issue of the nation's authenticity, including through the shaping the material environment principles of its life, through other spatial structures - urban planning, design, others. Authenticity in any country is key moment to the self-knowledge, the moral self-determination of people as a community on the planet. Architectural and urban planning space is a powerful instrument for the historical assessment of any national culture. The purpose of the article – to reveal the features of style interaction (combination) of old and new architecture in the conditions of the post-war revival of Ukrainian cities.

It is necessary to have mathematical models that allow such evaluation at the design stage in order to evaluate the effectiveness of protective barriers promptly. The purpose of the article. Development of a numerical multi-parameter model and computer program for evaluating the effectiveness of the protective barriers using near the highway to reduce the chemical contamination level of work areas. Methodology. A two-dimensional mass transfer equation is used for mathematical modeling of chemical hazardous substances spreading that are emitted from a car and spread near the highway. This simulation equation takes into account the wind direction, atmospheric diffusion, the intensity of chemically hazardous substance emission from the car, the emission source location, the car body and the location of protective barriers near the highway. The Navier − Stokes equation and the potential motion model both are used to solve the aerodynamics problem of determining the uneven air velocity field near the highway. An implicit splitting difference scheme is used to numerically integrate the vortex transfer equation. Two numerical schemes are used to numerically integrate the equation for the current function. An explicit difference scheme is used to numerically integrate the Laplace equation for the velocity potential. Based on the constructed numerical model the package of programs is developed. To solve numerically equation of pollutant transfer the finite difference schemes of splitting are used. Scientific novelty. To calculate the formation of chemical pollution areas for atmospheric air near the highway during emissions from vehicles numerical model is proposed. This model allow to estimate the protective barriers effectiveness for reducing air pollution in the working areas. Practical significance. Based on the developed model the code for quickly calculation of air pollution process both near the highway and in work areas protecting with barriers is created. Conclusions. The developed numerical model and the computer code implementing it allow to investigate the process of chemical hazardous substance spreading in the atmospheric air near the highway. The model allows to quickly determine the effectiveness of protective barriers using near the highway. The developed computer program can be implemented on low and medium power computers. The results of a computational experiment are presented.

Authors: SEDIN V.L. , ULYANOV V. Yu. , KOVBA V. V. , VOLNIANSKYI Yu. Yu.
Published: July 2022

Problem statement. The article presents the results of special non-normative research for saline clay soils sampled from excavations during the nuclear power plants’ construction at different times and in different countries. Of the NPP sites located in the arid climate zone, only the Crimean NPP, which is not yet under construction, the planned NPP in Uzbekistan and possibly the NPP in Egypt are close to the engineering and geological conditions relative to the described NPP site to a large extent. The purpose of the article. The researches’ purpose is to estimate the degree of leakages impact from technological pipelines for production water of different composition and temperature, which affect the soil properties of the foundations for responsible buildings and structures of NPPs and other critical energy facilities. The need for such research is obvious to ensure the safe operation of nuclear power plants, especially when NPP are located in difficult seismotectonic and geological conditions. Conclusions. The non-regulated method for investigating the plastic properties of clay soils proposed in this article is a combination of several already tested research methods. The essence and difference of this indirect method is to investigate the soils plastic properties only after their pretreatment at different times with ground water of different temperatures. The test process partially simulates the impact on soil bases of possible short-term (instantaneous) or long-term leakages from technological thermal water supply communications, which would result in significant ground water warming. As a work result, the upper horizons of the soils for some NPP sites were prone to soaking, including at elevated temperatures, but no fundamental differences from these impacts have yet been found. The results of these researches correlate quite well with the previously performed investigations on soils leaching in the upper part of the geological section of the NPP sites. As a result, the upper soil horizons of some NPP sites were prone to soaking, including at elevated temperatures, but no fundamental differences from these effects have yet been identified. The results of the conducted research correlate quite well with the previously performed studies on soil leaching in the upper part of the NPP sites geological section.

Raising of problem. When designing modern high-rise buildings, the priority tasks are: reducing energy consumption, increasing the level of comfort, safety, efficiency and environmental friendliness. Therefore, the urgent task is to create a toolkit for assessing the duration and cost of erecting high-rise buildings, taking into account the probabilistic effects of a changeable external environment, resource constraints of the project and compliance with modern requirements for construction facilities regarding energy efficiency, safety, quality and environmental friendliness of facilities, designed primarily for the needs of customers, investors. Purpose of the aricle. Development of a methodological approach to assessing the conditions for the construction of high-rise buildings and substantiating the effectiveness of options for design and organizational and technological decisions. Conclusion. To date, there is no unified approach to the development of design, organizational and technological decisions for the construction of high-rise buildings, taking into account the requirements for quality, energy efficiency, safety and environmental friendliness of facilities with existing resource constraints. The use of such tools in the assessment, analysis, substantiation and selection of rational design and organizational and technological decisions will improve the quality of high-rise buildings being erected with the efficient use of resources and at the same time reducing adverse environmental impacts by taking into account the complex impact of determining organizational, technological, technical and management factors for minimizing the negative impact of destabilizing factors in the design and production of construction work. The developed methodological approach to assessing the conditions for the construction of high-rise buildings and substantiating the effectiveness of options for design and organizational and technological decisions is focused on customers, investors, and can also be used by contractors, government bodies and local governments, in particular when forming contractual relations and holding contract auctions.

Authors: NECHYTAILO M.P. , NAHORNA O. K. , NESTEROVA O.V.
Published: July 2022

Problem statement. The main issues that arise during the operation of circulating cooling systems are the deterioration of thermal and hydraulic characteristics, as well as corrosion processes that lead to increased operating costs for the replacement of equipment and pipelines. This is due to both the input parameters related to water quality and the operating parameters of the system related to the evaporation coefficients and the temperature difference in the circuit. Methods. The research was performed on the basis of the analysis of Ukrainian and foreign scientific sources and reporting data on the specifics of the operation of circulating water supply systems. The influence of various factors on the mode of operation of the system has been studied as a result of our own research. Scientific novelty. The analysis of influence of determining factors on work of system of circulating water supply is carried out. The controlling factor in ensuring the reliability of the circulating water supply system is determined. Practical significance. Теоретичні викладки є важливими з огляду на те, що компанії, які займаються процесами охолодження, як правило, не мають у своєму штаті інженера, який би розбирався в процесах очищення води. Інженери проектувальники теплотехнічної частини проектів не навчаються за даною тематикою і також не розуміють проблему, пов’язану з відсутністю належної підготовки води. Conclusion. A large number of factors that determine the reliability of evaporative cooling systems, shows the complexity of forecasting and calculating its trouble-free operation. The main factors that determine the reliability of evaporative cooling systems include the chemical composition of water, temperature and purge. Blowing can be taken as a control factor in the operation of the reversible system, but the purge itself usually can not prevent the formation of scale, as some compounds exceed the saturation level and settle on heat exchange surfaces and other internal devices of the system. To ensure the reliability of the systems in most cases requires additional water treatment by chemical or physical methods.

Published: July 2022

Formulation of the problem. According to the official data of the Social Insurance Fund of Ukraine, in 2020, 6,646 victims of accidents / acute occupational diseases at work were registered, 393 cases were fatal. Compared to last year, the number of insured accidents increased by 51.3 % (4,394 such cases were recorded in 2019), the number of fatally injured persons decreased by 4.1 % (from 410 to 393). Introducing modern innovative projects to improve occupational safety will undoubtedly reduce occupational injuries and increase corporate social responsibility. The purpose of the article is to analyse well-known and promising innovative projects to enhancethe occupational safety of workers in Ukraine in modern conditions of the development of production technologies. Conclusion. Given the gradual integration of Ukraine into the European economic and social space, high rates of occupational injuries in Ukraine, the insufficient culture of occupational safety, it is recommended to implement innovative projects to improve occupational safety through a comprehensive approach that includes organisational and technical solutions. Based on the analysis, it is possible to enhance occupational safety by implementing a safety management system based on a risk-based approach, maintaining a safety calendar, new practice-oriented training (including life wrestling) and computer technology, 3D virtual reality technology during training and testing of staff knowledge. The increase of labour safety can be provided by implementing workplace automation projects, creating comfortable working conditions in the workplace, quality management, and optimisation of working hours with the use of sleep in the workplace. The use of innovative means of protection, tracking employees with the help of radiofrequency labels, fitness bracelets, drones will help increase occupational safety. Bactericidal ozone-free quartz lamps and bactericidal air recirculation should be used to disinfect air and surfaces in public transport in a pandemic.

The coronavirus COVID 19 pandemic is one more additional factor, which is a great source of stress affecting mental health of people. Being influenced by the regular stress for two years, people suffer from such psychological disorders as depression, anxiety disorders, posttraumatic stress disorders. The participants in the educational process are also exposed to the above-mentioned problems. In addition, distance learning, as a form of social isolation, intensifies negative influence of stress, even though it is a necessary measure to prevent this contagious disease. Under the current conditions of social uncertainty, some emotional impairments are inevitable and the students suffer from them. The paper is devoted to the investigation of mental and psychological health of students of Prydniprovska State Academy of Civil Engineering and Architecture. The human health as a condition of physical, mental and social well-being is considered from the perspective of the holistic approach.

Published: July 2022

Government Regulation in Lieu of Law (Perppu) No. 1 of 2013 about the Second Amendment to Act No. 24 of 2003 about Constitutional Court (MK) is an appropriate step to recover public trust to MK after the arrest of non-active Head of MK Akil Mochtar by Corruption Eradication Commission (KPK). Many crucial things are found  in Perppu No.1 of 2013 about MK and these are considered as the problem roots   but also the efficacious herbs to deter against the replicated corruption practice at MK. One of them is the supervision system of Constitutional Justices. Justices of  MK have been once becoming the object of the supervision of Judicial Commission (KY), but the release of the Verdict of Constitutional Court No. 005/PUU-IV/2006  has made the authority of KY to supervise Constitutional Justices degraded into inconstitutional. The verdict of Constitutional Court is final and binding, but it cannot still escape from erga omnes principle, meaning that the verdict is binding  in general term and also binding for the object of dispute.
