COMPARISON OF SYSTEMS OF FORECASTING THE DIRECTION OF CHANGES IN THE EXCHANGE RATE OF A FINANCIAL INSTRUMENT USING SIMPLE AND EXPONENTIAL MOVING AVERAGES
Authors:   KROK University, Savchenko Vadym
Published: July 2023

The range of actual research points to the fact that some technical analysis indicators have predictive power, and therefore trading strategies based on them have some applied value. This work examines some topical issues of the development and use of a trader's trading system, which relies on signals generated by indicators of technical analysis, particularly exponential and simple moving averages, in deciding to execute a stock transaction. The works of modern researchers, which describe approaches to using these indicators, are analyzed. In this context, the purpose of the study is to analyze the impact of exponential moving average settings and their combinations on the profitability of the trading system, as well as to compare the results of such a system with the results of a strategy built on simple moving averages and a combination of simple and exponential moving averages. Based on this, tasks that are solved using slides of this kind were formed. The technique of selecting technical indicators and their settings when creating a trader's trading system is proposed. Several variants of the formation and interpretation of the signal regarding the subsequent change in the rate of the financial asset generated by such a system are considered. The article also discusses the criteria for comparing strategies at the testing stage. The results of using different techniques were calculated and compared, and the optimal ones were determined according to the selected selection criteria. Trading simulations were performed for the EUR/USD currency pair, using weekly quotes from 1999 to 2023, based on which the optimal combination of sliders for use in the trading system was determined. It was noted that the strategy, based on exponential moving averages, needs additional optimization. Options for possible optimization and the corresponding tools that can be used are indicated. Based on the research results, it was concluded that the proposed approach to developing a trader's trading system could be used to perform actual exchange operations.

На основі соціологічного опитування визначено стан, проблеми, виклики та можливості туристичної індустрії. Ураховуючи зарубіжний досвід і результати авторського дослідження, розроблено науково-практичні рекомендації щодо відновлення туризму прифронтових громад в Україні після війни.
Архетипи української культури в балетмейстерській спадщині Павла Вірського
Authors: Козинко Лілія Леонідівна
Published: July 2023

Мета статті – проаналізувати особливості втілення архетипів української культури в балетмейстерській спадщині Павла Вірського. Методологія. У дослідженні застосовано історико-хронологічний підхід, методи історичний, теоретичний, системний, аналітичний, дедуктивний, індуктивний та узагальнення. Наукова новизна. У статті вперше проаналізовано особливості балетмейстерського методу та балетмейстерської спадщини Павла Вірського крізь призму архетипів української культури. Висновки. Архетип являє собою певні символічні схеми «колективного підсвідомого», які виступають глибинно-сутнісними основами нації та проявляються в різних сферах людського існування, трансформуючись із часом у нові форми. Кожна нація має національні культурні архетипи, які зберігаються в пам’яті етносу та спричиняють його прогрес, базуючись на глибинній основі. Зважаючи на дослідження фрагментів біографії П. Вірського та його інтерв’ю, вважаємо, що архетипи української культури присутні не лише у творчості, а й притаманні особистості балетмейстера. По-перше, без наявності означених архетипів у автора втілити їх на сцені було б неможливо. По-друге, в особистості балетмейстера можна виявити такі архетипи, як едукативність, глибинний оптимізм, цінність особи, особиста свобода, кордоцентризм та ін. Попри те, що особистість П. Вірського до сьогодні залишається недостатньо вивченою, можна припустити наявність у ній ряду архетипів. Сьогодні балетмейстерська спадщина П. Вірського вражає всіх злободенністю, глибиною та сучасністю ідей, що свідчить про наявність у постановках всеосяжних архетипів української культури. У результаті аналізу постановок балетмейстера було встановлено розкриття у них таких архетипів української культури: архетип глибинного оптимізму, архетип обрядовості, архетип особистої свободи, архетип природи, архетип гри з долею, архетип Матері тощо. Водночас слід наголосити на необхідності продовження розвідок з означеної проблематики.

“Digital Death and Immortality” in Contemporary Scientific Discourse
Authors: Kobyzhcha Nataliia
Published: July 2023

The purpose of the article is to analyze the peculiarities of the formation of digital thanatology as one of the new areas of scientific research, to outline its subject field, to operationalize the basic concepts, to make some adjustments to the conceptual apparatus of traditional thanatology (“Death Studies”).
The research methods are based on socio-communicative, systemic, historical and genetic approaches and the principles of digital humanities. The article also uses the methods of historiographical and source research, analysis of specialized publications on the research topic, descriptive approach, content analysis, etc.
The scientific novelty of the work lies in the fact that one of the first attempts to explicate the problem of “digital death and immortality” and to analyze the peculiarities of the formation of digital thanatology was made in the Ukrainian scientific discourse. Against the backdrop of the Russian-Ukrainian war, the author distinguishes the conceptualization of Ukraine’s cultural memory, the subject of which is the current state of the memorial landscape of Ukrainian culture as a complex, multilayered, heterogeneous entity, of which the digital memorial landscape is a significant structural element.
Conclusions. In digital reality, technologies create social relations, ranging from gadgets to nanotechnology, affecting both the process of dying and the ideas of death and immortality in their two modes – real and digital. It is about constructing common semantic boundaries within which not only death and immortality, the study of which is fundamentally impossible but also mediated relations, that is, the process of building relationships in collaboration with various fields of scientific knowledge. That is why “digital death and immortality” as a subject of study is a fundamentally interdisciplinary problem, and digital death studies are emerging as a specific cross-disciplinary field of research into the phenomenon of death in the digital environment. The overview of previous research on digital death and immortality provides an appropriate context for scientific work. It allows us to identify and develop promising areas for further studies, which are especially relevant against the backdrop of the Russian-Ukrainian war.

Published: July 2023

Abstract:  Human case studies are interesting to analyze from a variety of different perspectives. Regarding humanitarian cases in Indonesia, in 2022 there have been phenomenal human rights violations. Gus Dur's version of humanism is religious humanism adhering to the principles of Islamic teachings, but its actualization does not only touch the religious field. This study used a qualitative method with a literature review approach. The goal is to learn about KH Abdurrahman Wahid's thoughts on applying humanism theory to humanitarian issues.The research results obtained indicate that the basic foundation of the Indonesian nation is Pancasila, which consists of five precepts with fundamental values. Of course, in understanding these values, there is a meaning contained therein. This research tries to connect the humanitarian cases that occurred in Indonesia with the theory of humanism. The theory of humans serves as a foundation for KH Abdurrahman Wahid's ideas He is an intellectual figure and scholar whose knowledge comes from all over the country. Human cases are caused by the morality of each individual and socio-cultural, economic, political, and religious changes. In this case, Gus Dur actualizes human values that are just and adaptable to the concept of humanizing humans. In order to create world peace, a sense of involvement with the suffering of fellow human beings must be strengthened, not bypunishing those who suffer.

Published: July 2023

Sri Lanka has witnessed many examples of anti-Muslim sentiment and violence since the end of the civil war, especially in 2014 when an ethnic outbreak affected large numbers of people. Sinhala monks and Buddhists appear to have played an important role in covering it. Long wars and ethnonationalist ideology have resulted in a politico-religious shift related to “Buddhist extremism”, which engages in embracing and attacking Muslims. This study uses the "library research" method, whose main data includes: books, journals, articles, and references related to research. Sri Lankan Islamophobia and anti-Muslim sentiment manifests itself in several dimensions such as campaigns warning of Halal products in food, Muslim women's clothing (Burqa), slaughter of livestock in Muslim religious rituals, attacks on mosques and Muslim-owned businesses, and mandatory cremation. for all Sri Lankans regardless of religion at the time of the Corona Virus (Covid-19) outbreak, and the closure of Islamic schools.

RESEARCH ON DATABASE TYPES AND METHODS TO STANDARDIZE DATABASE TYPES IN THE FIELD OF TRANSPORT INFRASTRUCTURE
Authors:   The University of Danang, Anh Kiet Tran , Cong Duy Trinh
Published: July 2023

In truthfully, managing and storing information and data at the Department of Transport and its units in Da Nang city is still done manually and sporadically. Currently, the majority of them still utilize paper or digitized records but still save them separately on personal computers for managing and storing information regarding infrastructure, modes of transportation, etc. (.doc, .xls, .pdf files, Autocad, Video, Audio, Images, ...). Storing, maintaining, looking up, and discovering information is greatly hampered by this. There are still inconsistencies and delays in the deployment of information reporting, management information, digitization, and the availability of exploitation channels. In line with the Ministry of Transport's strategy, information technology should be used to manage transportation activities. Organizations and units in the transportation industry across the nation have developed and implemented various specialized software to assist in managing road transport. Software solutions have offered management information, enhancing professional management effectiveness. The deploying units use each software system separately, storing and handling specialized data in various ways. When it is necessary to handle and review the information of road transport vehicles, including registration information, vehicle registration, and information about traffic safety infractions, the program does not have a connection or data sharing capabilities. To access and compare data, expert employees must look for information and data on each software system to retrieve and compare data. The specificity of the data of each transport infrastructure project is that the data is very large and has many different formats; the information is updated regularly every year according to the maintenance, renovation, and upgrading process, etc. Traditional storage and data representation, like how database management systems and management software are used, will not meet the demand. In this paper, we propose a solution to build a centralized specialized database, have a specific organizational plan according to the specific characteristics of the industry, and be able to integrate data from specialized applications to connect and unify data between authorities. This will be a platform for sharing and exploiting data for professional management between authorities in the city and the whole country. The people and state management agencies highly appreciate this solution, which has been researched and implemented experimentally in Danang City.

Eradication therapy occupies a key place in the treatment of Helicobacter pylori (HP) infections. The presence of HP in the human body can affect the composition of gut microbiota in several ways, including the direct effect of infection or as a consequence of HP eradication regimes. Nowadays, one of the measures to increase the eradication therapy efficacy and reduce the probability of antibiotic-associated disorders is the strategy of gut microbiome modulation. The article discusses the HP effects on the gut microbiota, methods for probiotic correction in conditions of HP infection and eradication therapy. Probiotics have a destructive effect on the biofilm formed by HP, and its destruction can increase the efficacy of antibacterial therapy. The most rational regimen is the administration of probiotics before and during eradication, or at least for two weeks. At the same time, probiotics should include a variety of bacterial strains with proven efficacy and a high safety profile.

From the modern standpoint of theoretical histology, the term "histione" is commonly understood to mean a temporary or permanent cellular association, whose combined functional activity is aimed at achieving significant structural and other types of homeostasis. The model concept of histione can be successfully applied to analyze the structure, function and their disorders, including characterizing the so- called intestinal epithelial barrier. The available scientific data indicate the involvement of increased intestinal permeability syndrome in the pathomorphogenesis of a number of diseases, including ulcerative colitis and Crohn's disease, related to inflammatory bowel diseases (IBD), which makes the problem of regulating the intestinal barrier permeability one of the most urgent for pathologists and clinicians. The article combines and organizes ideas about the histione of the intestinal epithelial barrier, the patterns of its regulation mechanisms in patients with IBD, as well as methods for assessing intestinal permeability in this patient cohort. KEYWORDS: histione, intestinal epithelial barrier, increased intestinal permeability, Crohn's disease, ulcerative colitis, inflammatory bowel diseases.

On the subject part III: what is the subject’s end?
Authors: Frauen Jan-Boje
Published: July 2023

This article inquires into the end of the emergence of the subject from the objective world. Ultimately, there are two possibilities, one of which satisfies the fundamental law of logic that out of nothing, nothing comes, while the other satisfies the fundamental law of physics that entropy must always increase until it reaches its maximum in equilibrium. The first possibility is explained by a theory that was put forward independently by philosopher Johann Gottlieb Fichte and physicist John Archibald Wheeler. In this picture, a final endpoint of emergence posits the first creation of causation. The second picture is displayed by connecting Hugh Everett’s “many worlds” interpretation of quantum decoherence to the law of increasing entropy.

This article extracts the science-philosophical conclusion that it is impossible to decide between the two as either one seems compulsory depending on whether one starts from the subject’s law to emerge or from the object’s law to dissipate structure. However, abstract philosophical speculation about the end of time and emergence is defended as fully legitimate. Though neither side is falsifiable and there are no conclusions to be drawn practically, it is not “bullshit” since it is based on thorough philosophical reasoning and takes into account all that we know about the place we inhabit scientifically.

The Complexity of Leaving No One Behind: Unmasking and Emphasizing Multiple and Intersectional Marginalisation in India
Authors: Trivedi Mayur , Chaudhary Yogita
Published: July 2023

The global efforts towards achieving Sustainable Development Goals are now turning to cover the under-served and excluded people and places. Such efforts are also targeted towards people who are most likely to be left behind and unreached because of economic, social, and political marginalisation. This calls for a wider exploration of intersecting inequalities emanating from the confluence of spatial, economic and identity-based forms of marginalisation. This paper explores the intersectionality of geography and socioeconomic status in India at subnational levels using the multidimensional poverty Index (MPI) as a proxy measure of poverty and development. The mapping exercise indicated that most of the low-performing districts are clustered around administrative borders to form pockets of poor development, neglect and deprivations. This spatial marginalisation intersects with economic, ecological and social marginalisation. Addressing such complex marginalisation requires a comprehensive approach that acknowledges and addresses intersecting discrimination and disadvantage. By centring on social inclusion and equity in policy frameworks, embracing data-driven decision-making, and fostering collaborative partnerships, India can pave the way for sustainable and transformative development that truly leaves no one behind.

Background and Objectives The role of stress oxidative on cardiac disease prevalence has been studied by researchers and the effects of high-intensity interval training (HIIT) have not been specified clearly. Therefore, the aim of this study was to investigate the effects of HIIT training with caffeine consumption on myocardial oxidative stress in rats. Subjects and Methods Thirty-two male rats were randomly divided into four groups (eight rats per group): control, HIIT (TA), caffeine (CA), and HIIT + caffeine (TA+CA). One hour before exercise, caffeine was injected into the CA and TA+CA groups. HIIT was performed five days a week with 85-90% maximum running speed on a treadmill for eight weeks. Then, 48 hr after the last exercise session and anaesthetization, the left ventricular was removed and the superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) levels were measured by spectrophotometry. Results The results indicated that MDA levels in the CA+TA and CA groups significantly decreased compared to the control group (P<0.05). Also, the levels of SOD and CAT significantly increased in the three groups compared to the control group. Conclusion HIIT along with caffeine consumption can protect the cardiac tissue in rats and prevent heart injury.

Monitorar os equipamentos de academias é essencial para o crescimento bem-sucedido de estabelecimentos voltados para o segmento de atividades físicas, pois o desgaste dos aparelhos pode acarretar inconvenientes, que podem provocar desequilíbrios físicos e alterar a mecânica dos movimentos dos usuários. Este estudo teve o objetivo de identificar as cargas indicadas nos equipamentos anilhas, halteres e no aparelho Crossover e comparar com as cargas aferidas por dinamometria. As anilhas e halteres de 3 e 5 kg indicaram um desvio padrão baixo, sugerindo pouca variação nas cargas, já os halteres de 10 kg exibiram um desvio maior. A análise no Crossover apresentou resultados variáveis, pois a indicação e a mensuração não se alinhavam. A correlação entre as posições apresentou maior similaridade, no entanto, ainda com assimetrias.

Syzygium cumini is a medicinal plant traditionally used to treat cardiometabolic disorders. This study proposed to evaluate the cardiopreventive effect of the hydroalcoholic extract from the S. cumini leaves (HESc) on ischemic injury isoproterenol (ISO)-induced in rats. Male albino Wistar rats (Rattus norvegicus) were pre-treated with HESc or water for 15 days. They received a challenge with ISO (85 mg/kg) on the 14th and 15th days for induction of ischemic injury. For all animals were obtained electrocardiographic parameters predictive of the lesion in addition to evaluation of troponin I changes in animals. We also realized a phytochemical screening, and in vitro antioxidant activity including 1,1-Diphenyl-2-picrylhydrazyl radical. HESc was found to be rich in flavonoids, and high antioxidant potential. Addictionaly, increased the survival rate and reversed ventricular remodeling caused by isoproterenol-induced ischemic injury in a dose-dependent manner. Inhibition of ST segment elevation, impairmentf QT interval prolongation, reduction of Troponin I levels also were observed in animals pretreated with HESc. Our results suggest that pretreatment with HESc reduces myocardial injury and simple phenols and flavonols are likely to be responsible for its effect on cardiomyocyte integrity, confirming that S. cumini is a promising plant source of bioactive compounds for the treatment of ischemic syndromes.

The diagnosis of breast cancer triggers an emotional impact, generating a variety of feelings. Spirituality and religiosity and support from family, friends and professionals is fundamental in coping with this period of adversity. The objective of this study was to understand how women’s spirituality and social support network help in coping with the diagnosis of breast cancer. This is a qualitative study, carried out in an oncology hospital, with the participation of forty women with breast cancer. For data collection, semi-structured interviews were applied, analyzed using Content Analysis. The thematic axis “Support” was composed of the categories “Spirituality/Religiosity” and “Social support”. Faced with the discovery of a disease that leads to suffering and death, a support network is needed to cope with cancer. Spiritual support was unanimous and faith favored overcoming the initial impact, infusing strength to face the diagnosis. The family represented a unique support, helping with health care and with words of encouragement. Professional support occurred through guidance, kindness in assistance and motivation. The pandemic has impacted social isolation. However, it brought benefits such as greater contact with the family. To cope with the cancer diagnosis, the women studied had social and spiritual support, through emotional support, material and practical resources, received from family members and significant others. These are strategies that need to be explored by the multidisciplinary team at the time of diagnosis, minimizing the impact and accepting the demands presented by women with breast cancer.

We report plasmon-free polymeric nanowrinkled substrates for surface-enhanced Raman spectroscopy (SERS). Our simple, rapid and cost-effective fabrication method involves depositing a poly(ethylene glycol) diacrylate (PEGDA) prepolymer solution droplet on a fully polymerized, flat PEGDA substrate, followed by drying the droplet at room conditions and plasma treatment, which polymerizes the deposited layer. The thin polymer layer buckles under axial stress during plasma treatment due to its different mechanical properties from the underlying soft substrate, creating hierarchical wrinkled patterns. We demonstrate the variation of the wrinkling wavelength with the drying polymer molecular weight and concentration (direct relations are observed). A transition between micron to nanosized wrinkles is observed at 5 v% concentration of the lower molecular weight polymer solution (PEGDA Mn 250). The wrinkled substrates are observed to be reproducible, stable (at room conditions) and, specially, homogeneous at and below the transition regime, where nanowrinkles dominate, making them suitable candidates for SERS. As a proof-of-concept, the enhanced SERS performance of micro/nano-wrinkled surfaces in detecting graphene and hexagonal boron nitride (h-BN) is illustrated. Compared to the SiO2/Si surfaces, the wrinkled PEGDA substrates significantly enhanced the signature Raman bands intensities of graphene and h-BN by a factor of 8 and 50, respectively. 
Health eﬀects, environmental impacts, and photochemical degradation of selected surfactants in water

Surfactants are depended upon worldwide as cleaning agents. Their usage in such large quantities means that their waste and the potential for pollution are high. Many studies have been done over the last three decades encompassing treatment, alternatives to non-biodegradable surfactants, and the environmental impact. It has been found that although certain surfactants may not be directly toxic, when their concentrations are high in soil, they can act as agents to release toxic pollutants such as polychlorinated biphenyls (PCBs). The focus of this study is to review recent advances in the toxicology, the environmental fate, and the treatment of selected surfactants. In addition, photolytic and photocatalytic degradation of linear alkylbenzene sulfonate in water is presented.

The identification of non-ideal flows in a continuous-flow mixing of non-Newtonian fluids is a challenging task for various chemical industries: plastic manufacturing, water and wastewater treatment, and pulp and paper manufacturing. Non-ideal flows such as channelling, recirculation, and dead zones significantly affect the performance of continuous-flow mixing systems. Therefore, the main objective of this paper was to develop an identification protocol to measure non-ideal flows in the continuous-flow mixing system. The extent of non-ideal flows was quantified using a dynamic model that incorporated channelling, recirculation, and dead volume in the mixing vessel. To estimate the dynamic model parameters, the system was excited using a frequency-modulated random binary input by injecting the saline solution (as a tracer) into the fresh feed stream prior to being pumped into the mixing vessel. The injection of the tracer was controlled by a computer-controlled on-off solenoid valve. Using the trace technique, the extent of channelling and the effective mixed volume were successfully determined and used as mixing quality criteria. Such identification procedures can be applied at various areas of chemical engineering in order to improve the mixing quality.

Mixing is a critical unit operation, which is widely used in chemical and allied industries. Mixing of non-Newtonian fluids is a challenging task due to the complex rheology exhibited by these fluids. Pseudoplastic fluids with yield stress are an important class of non-Newtonian fluids. In this study, we utilized ultrasonic Doppler velocimetry (UDV) to explore the flow field generated by different impellers in the agitation of xanthan gum solutions and pulp suspensions, which are yield-pseudoplastic fluids.
