Published: August 2024

This study is aimed to report and analyze the modern plants use in the historical rural localities of Chernihiv Polesie (Ukraine). The research materials were collected in two stages. At the first stage the main useful of the local natural flora were identified. At the second stage a sociological survey of adult local inhabitants on the plants use was conducted. The main groups of useful plants of the historical localities were established. The modern use of plants was analyzed. It was found that most plants were used by the local inhabitants for their own needs. However, certain edible, fodder and techniacal plants are a source of income for the local inhabitants. In the historical localities of Chernihiv Polesie all the traditional for the region ways of using the natural flora plants have been preserved (but to varying degrees). The degree of modern use of plants is primarily determined by the peculiarities of the vegetation (in particular, the predominance of pine, mixed forests and floodplain meadows) and financial incentives. This primarily applies to Vaccinium myrtillus gathering and laying hay in for the own use and sale. The local inhabitants use the plant resources lesser than the existining resource potential.
TECHNOLOGY AND LANGUAGE MANIPULATION AS THREATS IN THE ONLINE RETAIL BUSINESS
Authors: ROYA Witness , NGCOBO Sandiso
Published: August 2024

The facilitation of technology has enabled customers to conduct online transactions regardless of geographical boundaries. However, the cut-throat nature of business often trumps observance of ethics as retailers appear not to do enough to protect consumers from becoming victims of scams. Christensen's theory of disruptive technology was used as a lens to show how the emergence of new technology may pose a threat to the continued existence of established markets and expose customers to online scammers. The study purposively sampled messages posted on two Facebook pages which claim to represent Tekkie Town, a sneakers store in South Africa, and responses from some users. To enhance chances of making an informed analysis, Critical Discourse Analysis was used to examine language techniques utilized by online advertisers, legit and fake, and comments from customers regarding their online shopping experiences. Results indicate retailers do not take special attention to monitor fake websites designed to scam their clients. Instead, it is customers who end up alerting stores to fake posts. We encourage business managers to uphold excellence practices and protect their customers by taking special measures to prevent scammers from easily copying their logos and scamming customers, which could harm their businesses.
Faktor-faktor yang memengaruhi behavioral intention nasabah bank umum swasta di Kepulauan Riau
Authors: David Tonny , Keni Keni
Published: August 2024

The consistent growth of banking sector in Indonesia indicates that people have a high intention to interact with banks, whether for saving, making transaction or applying for loans. However, this interaction tends to only focus on large scale banks that are already widely known by the public, so it becomes an obstacle for small scale bank to develop, such as the market share of sharia commercial banks which only 7.09% in 2022. For this reason, the research aims to test whether customer satisfaction, perceived value and corporate image can influence the behavioral intention of bank’s customers in the Riau Islands. This research obtained data from 107 respondents who were bank’s customers in the Riau Islands through an online questionnaire. The data was measured by using a Likert scale and analyzed by using Smart-PLS software by using the Partial Least Square-Structural Equation Modeling (PLS-SEM) method. The results of this research indicate that customer satisfaction and perceived value have a positive and significant influence on behavioral intention. However, corporate image has a significant effect on behavioral intention. Based on these findings, it is recommended that bank’s management in the Riau Island focus on increasing customer satisfaction dan perceived value for increasing behavioral intention in customers.
Pertumbuhan sektor perbankan di Indonesia yang terjadi secara konsisten mengindikasikan bahwa masyarakat memiliki intensi yang tinggi untuk berinteraksi dengan bank, baik untuk menabung, bertransaksi, maupun mengajukan pinjaman. Namun, interaksi tersebut cenderung hanya berpusat pada bank berskala besar yang sudah dikenal secara luas oleh masyarakat, sehingga menjadi penghambat bagi bank berskala kecil untuk berkembang, seperti pangsa pasar bank umum syariah yang hanya sebesar 7.09% pada tahun 2022. Oleh sebab itu, penelitian ini bertujuan untuk menguji apakah kepuasan nasabah, nilai yang dirasakan, dan citra perusahaan dapat memengaruhi behavioral intention nasabah bank di Kepulauan Riau. Penelitian ini memperoleh data dari 107 responden yang merupakan nasabah bank di Kepulauan Riau melalui kuesioner online. Data tersebut diukur dengan menggunakan skala Likert dan dianalisis melalui perangkat lunak SmartPLS dengan metode Partial Least Square-Structural Equation Modeling (PLS-SEM). Hasil penelitian ini menunjukkan bahwa kepuasan nasabah dan nilai yang dirasakan mempunyai pengaruh positif dan signifikan terhadap behavioral intention. Namun, citra perusahaan berpengaruh signifikan terhadap behavioral intention. Berdasarkan temuan tersebut, disarankan agar manajemen bank di Kepulauan Riau berfokus pada peningkatan kepuasan nasabah dan nilai yang dirasakan untuk meningkatkan behavioral intention pada nasabah.

Published: August 2024

Solar desalination technology has been one of the effective solutions to tackle the problem of water scarcity. A number of studies have been conducted at our water research group to determine which variable influences the quantity of distilled water produced by an independent solar desalination unit. Aims: This study was aimed to design and optimize a novel solar desalination unit and field-tested using the best variable from the previous studies. Methodology and results: Variables used from the previous studies were evaluated to obtain the best values for each parameter, those are: glass cover inclination, gap distance between water and glass cover, insulation thickness, water depth, and water mass flow rate. Those best values were then implemented in the optimized basin design, delivery mechanisms, evaporation techniques, and heat isolation methods. The optimized design can generate up to 2,778.2 mL/m2/8hrs of distilled water with an efficiency of 23.35% in preliminary test, and was field tested at Batukaras Beach, where it produced up to 902 mL/m2/8hrs with an efficiency of 13.56%. Conclusion, significance and impact study: Meteorological parameters and environmental conditions are important factors that greatly affect the performance and productivity of the desalination unit. The relative humidity is inversely proportional to the volume of distillate water, where the smaller the value, the greater the amount of distillate water that can be produced, and it has significant impact on the productivity of the prototype. The quality of the distillate water produced still needs improvement on the parameters of pH, turbidity, and total coliform.

Neuroinfecções e psiquiatria
Authors: Câmara Fernando Portela
Published: August 2024

Os grandes transtornos psiquiátricos não possuem uma causa definida, dada a peculiar complexidade da formação dos sintomas mentais e sua sensibilidade a impactos mínimos sobre o fluxo de neurotransmissores nas vias neurais. Neste trabalho discutimos as neuroinfecções em seu âmbito geral, neuropatológico, e, no particular, como uma possível origem de doença mental como causa primária. Neste particular, apresentamos evidências epidemiológicas que sugerem um modelo infeccioso de transtorno afetivo, implicando os vírus Nipah e Borna como uma das causalidades prováveis de doença mental.
Considerações a respeito da fragilidade das hipóteses em psiquiatria e em psicofarmacoterapia
Authors: Bueno João Romildo
Published: August 2024

Nesse trabalho, um esboço de ensaio, pretende-se através a utilização de um exemplo escolhido ao acaso demonstrar-se a fragilidade das hipóteses vigentes no domínio da psiquiatria e das neurociências. Os exemplos adotados não são julgados em seu “valor”, mas apenas e simplesmente se devem ou não ser aceitos como base de “classificações” e de criação de “diretrizes”, “algoritmos” ou “árvores decisórias” para orientar “diagnóstico” ou “evidências” de que um ou outro critério deva se sobrepor a outro no que tange à escolha de uma intervenção terapêutica. O cerne do trabalho é a utilização do “recurso do método” como parte indispensável do pensar psiquiátrico.

Regional Dimension in European Union: Shaping Key Performance Indicators for Financial Institutions. Doctoral Thesis
Authors:   ,   Rīga Stradiņš University, Černiševs Oļegs
Published: August 2024

The rise of fintech, or the combination of digital financial services and technology, represents a turning point in the evolution of financial institutions in an ever-changing financial environment. This Thesis explores the operational aspects and regulatory frameworks in the European Union. Fintechs are able to effectively provide services across the EU market due to the modern EU legislation, the passporting mechanism, in particular. These services involve complex cross-border and interregional operations, which are associated with risks and connected to KPIs. Chapter 1 presents the systematic literature review to determine the lacuna in the issue of KPIs formation for financial institutions. The genesis of fintech is also explored, with specific emphasis on the regional dimensions. The taxonomy of fintech is presented. The region of research application is identified. Special attention is paid to the operations of the European Central Bank (ECB) as a financial regulator in the EU region. Chapter 2 reviews and analyses the impact of EU regional and national policies on financial institutions. The conditions for the functioning of fintech are compared, highlighting the regional peculiarities. The taxonomy of digital financial products and their representation in different EU regions is presented. The comparative analysis between e-money products and crypto-based assets demonstrates their characteristics and operating environment. The taxonomy and life cycle of digital assets are shown. It also identifies the pricing components for digital and cryptocurrencies. Chapter 3 determines the KPIs and KRIs for financial institutions. This is done on the basis of the expert panel's estimates. The currently limited use of appropriate KPIS is discussed. In addition, the development of financial services in smart cities is shown and the regional aspect of fintech functioning in smart cities is specified. The opportunities for smart cities to use fintech and financial services as part of the sharing economy are also identified. In this chapter, two statistical models are presented. The PLS-SEM analysis is used to evaluate the relationships between the risks of internal processes and KPIs (Model 1) and the risk of compliance with regional legislation and KPIs (Model 2). At the end of the study, conclusions are drawn and recommendations formulated. The Doctoral Thesis was developed at Rīga Stradiņš University, Latvia.

Disjunctivism and the phenomenology of attention
Authors: Korobkov L. G.
Published: August 2024

J. Campbell`s disjunctivist theory of perception is based on an outdated model of attention, which maintains that the focus of attention is analogous to the beam of a spotlight. Meanwhile, some studies challenge this view and suggests that attentional selection can be object-based. The narrow target of this article consists in clarifying what is at stake between attention-first and consciousness-first strategies. The latter assumes that one could explain what attention is by specifying how some proper subset of the conscious field comes to be foregrounded. Campbell who adopts it faces a serious challenge in explicating the phenomenon of unconscious attention.
Local self-government bodies in the process of municipal reform: trends and patterns of development
Authors: Zazulina M. R.
Published: August 2024

The article is devoted to the study of the development patterns of the local government system in the Russian Federation. The submission to the State Duma of the Russian Federation of the draft Federal Law «On the general principles of the organization of local self-government in the unified system of public authority» in December 2021 means the preparation of a new stage of municipal reform and makes it relevant to study long-term changes in the institutional organization of local self-government. The purpose of the study is to analyze changes in the structure of local self-government bodies and the rules of their formation at each stage of the development of this institution, as well as to identify the main patterns of this process. The analysis of the legislative base regulating the structure and rules of formation of local self-government bodies has been carried out. The data related to the development of the local government system provided by the Ministry of Justice of the Russian Federation were analyzed. It is shown that the structure of local self-government bodies has not undergone significant changes. However, there have been changes in the ways of forming local self-government bodies, which reflect the trend towards their loss of institutional independence and integration into a single system of public power. This trend appeared at the stage of implementation of the Federal Law on Local Self-Government in 2003 and was consolidated in the new Draft law on Local self-government submitted to the State Duma of the Russian Federation in 2021. It is concluded that there is a tendency to increase the dependence on federal and regional legislators of local self-government bodies. For the institute of heads of municipalities, the loss of institutional independence was clearly manifested by the introduction of the procedure for electing heads by competition, displacing both election at municipal elections and election from the Council of Deputies. The formation of representative bodies, having passed the stage of delegating deputies to higher levels, returns to the model of direct elections. However, this happens in the context of the rejection of a two-tier system of local self-government.

Development of theaflavins-loaded albumin nanoparticles and in silico analysis of theaflavins: BSA interaction
Authors: Payas Salim , Abul Kalam Azad Mandal
Published: August 2024

Theaflavins (TFs), bioactive compounds present in black tea manufactured from Camellia sinensis leaves have potential health benefits. Due to their instability and low bioavailability, we have encapsulated TFs into albumin nanoparticles (Alb-TFs-NP) and characterized them using different techniques. The mean particle size of Alb-TFs-NP was 125.9 nm with a low (0.23) polydispersity index and Zeta potential of -76.8 mV. Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) analysis revealed a spherical shape of Alb-TFs-NP with a smooth surface. The fluorescence of bovine serum albumin (BSA) and TFs was at 280 nm and 660 nm excitation and 690-700 nm emission respectively. The BSA-TFs complex interacts at distinct amino acid binding sites with good docking energy of TF1 (-10.5 kcal/mol-1), TF2 (-11.1 kcal/mol-1), TF2a (-11.2 kcal/mol-1) and TF3 (-10.4 kcal/mol-1) at the BSA active site. Primarily hydrogen bonding was involved in the BSA-TFs interaction. The study could further research the transport distribution and bioactivities of TFs in the human body.
Role of Quaternary Aminoacid Derivatives and Ion Homeostasis in Amelioration of Salinity Stress
Authors: Reddikavitha Ethakoti , Sathiavelu Arunachalam
Published: August 2024

Salinity is a detriment to plant production throughout the world. Salinity impacts the quality of irrigation water. Understanding salt stress in plants necessitates complex physiological and metabolic stages. Preserving turgescent cells and regulating the water potential to maintain a proper water balance among the key responsibilities of osmoprotectants, long-term, high salt doses can slow down plant growth and development by interfering with physiological processes like nutrient imbalance, membrane damage, enzyme inhibition and metabolic dysfunctions like photosynthesis, hormone production and ion homeostasis, all of which can result in plant death. Hyperionic and hyperosmotic stress are also caused by prolonged, high salt doses. Osmolytes (such as proline and glycine betaine) accumulate under different salt levels, antioxidant enzyme activities increase and eventually some of the negative effects of NaCl toxicity on plants are mitigated. Plants under salt stress may have higher concentrations of reactive oxygen species (ROS) such as superoxide radicals (O2) and hydrogen peroxide (H2O2). Ion homeostasis is crucial for plants during abiotic stress conditions.

Authors: Харламова М.Д. , Романовская К.С. , Борисова А.Р. , Вышелесский А.Б.
Published: August 2024

Изучен качественный состав выбросов, образующихся при разложении белковых и липидных фракций биоорганических отходов, а также птичьего помета, определено соотношение в них легколетучих органических соединений. Показано, что в составе выбросов на первой стадии компостирования присутствуют одиннадцать классов ЛОС, в том числе обладающие сильно выраженным запахом, такие как индол, метантиол, диметилсульфид и др. Оценена эффективность действия экспериментального биопрепарата «Ликвидатор-2», используемого для уменьшения запаха и ускорения биодеградации при воздействии на белковые фракции биоорганических отходов и птичьего помета, изучена динамика изменения состава выбросов при добавлении экспериментального биопрепарата «Ликвидатор-2». Показано, что в наибольшей степени биопрепарат оказывает воздействие на ЛОС, образующиеся при разложении рыбных фракций биоорганических отходов. Отмечена необходимость модификации состава биопрепарата для некоторых фракций отходов с целью обеспечения деструкции доминирующих веществ, обладающих сильно выраженным запахом. Предложена методика более простого и экономичного отбора проб и последующей идентификации летучих органических соединений (ЛОС), выделяющихся при разложении отдельных фракций биоорганических отходов, с использованием сорбента, которая позволяет заменить использование дорогостоящих сорбционных трубок Tenax.

The qualitative composition of emissions formed during the decomposition of protein and lipid fractions of bioorganic waste, as well as bird droppings, has been studied, and the ratio of light volatile organic compounds (VOCs) in them has been determined. It has been shown that the emissions at the first stage of composting contain eleven classes of VOCs, including those with strong odors such as indole, methanethiol, dimethyl sulfide, and others. The effectiveness of experimental biological product “Liquidator-2” used to reduce odor and accelerate biodegradation when exposed to protein fractions of bioorganic waste and bird droppings has been evaluated. The dynamics of changes in the composition of emissions when adding the experimental biological product “Liquidator-2” has been studied. The biological product has been shown to have the greatest impact on VOCs formed during the decomposition of fish fractions of bioorganic waste. The need to modify the composition of the biological product for some fractions of waste in order to ensure the destruction of dominant substances with a strong odor was noted. A method for simpler and more economical sampling and subsequent identification of VOCs emitted during the decomposition of individual fractions of bioorganic waste using a sorbent has been proposed, which allows for the replacement of expensive Tenax sorption tubes.

Published: August 2024

Асимметрию морфологических частей растений обычно связывают с загрязнением воздуха, однако, очевидно, что вносить вклад в результаты биоиндикации могут различные характеристики почвы. Участки исследования располагались в северо-таёжной природной зоне (г. Ухта, Россия) в разных направлениях света от условного центра. На каждом участке были проведены биоиндикация по флуктуирующей асимметрии (ФА) листьев B. pendula (10 деревьев, по 10 листьев с каждого), а также химические и физико-химические анализы почвы. Коэффициенты ФА изменялись от 0,064 до 0,076 при показателе для незагрязненных территорий менее 0,04. Корреляционный анализ Пирсона показал, что снижение содержания органического вещества в почве и уменьшение уровня рН (солевая вытяжка) увеличивает ФА у березы: r = ‒0,49 и r = ‒0,42 соответственно. Нормативы содержания металлов в почве не были превышены, однако связь ФА с содержанием их подвижных форм наблюдалась для Pb, Mn, Cu: r равны 0,6, 0,36, 0,35 соответственно. Комплексный анализ результатов показывает, что результаты биоиндикации по ФА листьев B. pendula необходимо объяснять не только состоянием воздушной среды, но и почвенной.

The asymmetry of the morphological parts of plants is usually associated with air pollution. Obviously, different soil characteristics can influence the results of bioindication. The study sites were located in the north taiga natural zone (Ukhta, Russia) in different directions of the world from the conditional center. Bioindication of the fluctuating asymmetry (FA) of B. pendula leaves (10 trees, 10 leaves each), as well as chemical and physico-chemical analyses of the soil were carried out at each site. FA coefficients ranged from 0.064 to 0.076 with an indicator for uncontaminated areas of less than 0.04. Pearson's correlation analysis showed that a decrease in the content of organic matter in the soil and a decrease in the pH level (salt extract) increases FA in birch: r = ‒0.49 and r = ‒0.42, respectively. The standards for the content of metals in the soil were not exceeded, however, the relationship of FA with the content of their mobile forms was observed for Pb, Mn, Cu: r equal to 0.6, 0.36, 0.35, respectively. A comprehensive analysis of the results shows that the results of bioindication by FA of B. pendula leaves must be explained not only by the state of the air environment, but also by soil indicators.

Событие риска информационной безопасности можно трактовать как потери банка, связанные с несовершенством систем безопасности: уязвимости DDoS атакам, вирусным заражениям, несовершенством систем фрод-мониторинга. Проект положения Центрального банка Российской Федерации о системе управления операционным риском в кредитной организации и банковской группе предполагает учет компоненты этого риска в расчете объема капитала покрытия потерь. Взаимосвязь качества моделей фрод-мониторинга и расходов, связанных с возмещением этих потерь, а также увеличение объема капитала для покрытия операционных рисков может быть выражена в матрице ошибок классификации алгоритмов машинного обучения. В данной статье предлагается краткий обзор законов и нормативных актов, регулирующих применение антифрод-систем и оповещение регулятора о событиях соответствующего риска. Рассматриваются существующие верхнеуровневые метрики для управления и количественной оценки риска кибермошенничества. Указываются явные недостатки этих метрик и приводятся примеры, указывающие невозможность их неверного понимания организациями. Предлагается ввести новый показатель, корректирующий эти количественные параметры оценки.

Information security risk event can be interpreted as bank losses associated with imperfect security systems: vulnerability to DDoS attacks, virus infections, imperfection of fraud monitoring systems. The draft regulation of the Central Bank of the Russian Federation on the operational risk management system in a credit institution and a banking group involves taking into account the component of this risk in calculating the amount of capital to cover losses. The relationship between the quality of fraud monitoring models and the costs associated with reimbursing these losses, as well as an increase in the amount of capital to cover operational risks, can be expressed in a matrix of errors in the classification of machine learning algorithms. This article provides a brief overview of the laws and regulations governing the use of anti-fraud systems and notifying the regulator about events of the corresponding risk. Existing high-level metrics for managing and quantifying the risk of cyber fraud are considered. The obvious shortcomings of these metrics are pointed out and examples are provided to indicate that they cannot be misunderstood by organizations. It is proposed to introduce a new indicator that corrects these quantitative parameters of the assessment.

Сформулирована постановка задачи и обоснованы требования для данного класса орбитальных группировок. Предложен подход к формирования баллистической структуры разнородной орбитальной группировки, реализуемой на основе взаимной синхронизации нескольких орбитальных структур космических аппаратов путем сдвига одной структуры относительно другой по прямому восхождению восходящего узла. Предложенная методика позволяет получать относительное расположение плоскостей двух орбитальных группировок, обеспечивающее максимум эффективности наблюдения.

The method of forming the ballistic structure of a heterogeneous orbital grouping in the composition of radio-technical and radar survey spacecraft that provide observation of the Earth’s surface is considered. The problem statement is formulated and the requirements for this class of orbital groupings are justified. An approach to the formation of a ballistic structure of a heterogeneous orbital grouping is proposed, which is implemented on the basis of mutual synchronization of several orbital structures of spacecraft by shifting one structure relative to another along the direct ascent of the ascending node. The proposed method allows us to obtain the relative position of the planes of the two orbital groupings, which ensures maximum observation efficiency.

Обоснована необходимость обнаружения и коррекции ошибок в цифровых системах передачи данных и определены требования к методам обеспечения их помехо-отказоустойчивости. Предложена регулярная процедура адаптации кода, исправляющего одиночные байтовые ошибки, возникающие в физических средах каналов связи, для обнаружения и коррекции байтовых ошибок в арифметико-логических устройствах процессоров цифровых систем передачи данных. Выявлены закономерности, определяющие соотношения между арифметико-логическими операциями и значениями контрольных разрядов линейного кода относительно данных операций. Показано, что данные закономерности позволяют сформулировать правила получения значений поправок к контрольным разрядам кода для обнаружения и коррекции одиночных байтовых ошибок при использовании алгебраического линейного кода с синдромным декодированием. Предлагаемый метод защиты от одиночных байтовых ошибок устройств обработки информации позволяет минимизировать влияние кодирования (декодирования) информации на быстродействие арифметико-логического устройства процессора за счет замены циклической процедуры кодирования информации на алгебраическую с синдромным декодированием.

The necessity of error detection and correction in digital data transmission systems is justified and the requirements for methods of ensuring their noise and fault tolerance are determined. A regular procedure for adapting the code that corrects single byte errors that occur in the physical environments of communication channels for detecting and correcting byte errors in arithmetic-logic devices of processors of digital data transmission systems is proposed. The regularities that determine the relationship between arithmetic and logical operations and the values of the control bits of the linear code relative to these operations are revealed. It is shown that these regularities allow us to formulate rules for obtaining the values of corrections to the control bits of the code for detecting and correcting single byte errors when using an algebraic linear code with syndrome decoding. The proposed method of protection against single byte errors of information processing devices makes it possible to minimize the impact of encoding (decoding) information on the speed of the arithmetic-logical device of the processor by replacing the cyclic information encoding procedure with an algebraic one with syndrome decoding.
