Authors:   Peter the Great St. Petersburg Polytechnic University, Volodin Aleksandr A. , Degtereva Victoria A. ,   Peter the Great St. Petersburg Polytechnic University
Published: April 2023

This work is considered as the subject of consideration of the information and telecommunications meeting of public authorities of St. Petersburg (authorities of the Russian Federation, territorial structural divisions of the federal authorities of the Russian Federation and local governments) and its citizens. The aim of the work is a generalized analysis of a prospective review of existing contacts of public authorities, justification in the authorities of St. Petersburg, with the implementation of ontological modeling of work in the “black box” standard and the economic evaluation of competitive products that are currently being implemented using G2G models. In the course of the study of public administration, the authors come to conclusions about problems in the channels of interaction between a person and a civil servant, about the difficulties and losses in the implementation of work within the apparatus with data on excessive budget expenditures for their maintenance and the fundamental absence of a unified corporate system, which can be significant as direct, and indirect expenses of the budget of St. Petersburg on information and telecommunication interaction within the state apparatus and with citizens, creating a complexity that largely limits the sphere of influence.

Published: April 2023

The article reveals the results of an expert survey aimed at testing hypotheses about trends in the development of territorial strategic planning in Russia over 25 years of its history. To do this, periodization was carried out with the allocation of four periods: initiative innovative strategizing (1997–2005); mass strategizing, strengthening regulation (2006–2013), strategizing according to 172-FZ (2014–2019); strategizing in turbulence (2020–2022). In order to quantify the results, six scales are proposed to measure the degree of presence of certain aspects of the strategy: originality – conventionality, lapidary – specification, creativity – measurability, ambitiousness – pragmatism, self-development – paternalism, publicity – privacy. Thus, 34 competent experts evaluated the presence of each of the six aspects in each of the periods on a ten-point scale. On all scales, there was a shift in the mean and median scores from the left (one point) to the right (10 points) edge of the scale. The usefulness of strategic planning for the development of cities and regions in all periods was assessed positively, but with a downward trend. According to the experts’ answers, seven terms were identified that are included in the semantic core of strategies for most of its history: quality of life, sustainability, territory (space), competitiveness, cluster, agglomeration, investment. As a result, it was stated that strategizing in Russia in the period 1997–2022 moved from autonomy to centralization, strategists turned from independent actors into performers. The use of strategies for other purposes has led to a decrease in utility, which is especially evident in a period of turbulence.
TRANSPORT OF THE EAST OF RUSSIA IN THE CONTEXT OF GEOPOLITICAL AND GEO-ECONOMICAL CHANGES
Authors:   Economic Research Institute Far Eastern branch of the Russian Academy of Sciences, Bardal Anna B.
Published: April 2023

The dynamics of the indicators of the transport complex of the Far East is considered against the background of the consequences of the COVID-19 pandemic, economic sanctions and changes in the foreign policy conditions of the modern period. General trends in the segment of passenger transportation are highlighted. In 2020, a decline in passenger traffic was recorded at a rate lower than the national average. The factors that determined the smaller scale of the decline in traffic in this segment are considered. The dynamics of the cargo work of the Far Eastern transport complex is presented, which contradicts the negative trends of general processes. It is shown that servicing transit-export cargo flows to Asian countries determined the growth of performance indicators in the cargo segment for the rail and sea modes of transport in the macroregion during the pandemic. The increase in the work of the transport complex of the Far East, associated with a change in the logistics schemes of foreign trade interactions under the influence of economic sanctions, is argued. Emerging problems are identified: imbalance in the capacity of modes of transport, lack of supply of infrastructure in relation to demand, increased risks of transport services for the regional economy. Directions for further research are formulated.

In response to the search for solutions to the problems of sustainable development of society, the formation of an environmental economy took place, one of the priorities of which is the transition to the concept of a circular model based on the principles of isolation. The circular economy is a universal way of sustainable development, which allows, on the basis of technical and technological progress and a continuous stream of innovations, to overcome not only economic and environmental problems, but also social stratification. The circular model ensures national economic efficiency by cycling, slowing down and narrowing resource and consumer flows. The transformation of flows is achieved through the formation of production-consumer ecosystems, collaborations and intersectoral integration, which shifts the minimum object unit towards the mesolevel. A single circular economic system (CES) involves the inclusion in its elemental composition of many weakly affiliated entities, which in the «as is» situation are focused on ensuring private commercial efficiency through the implementation of linear models. The scientific novelty of the study lies in the development of theoretical and methodological foundations for ensuring the effectiveness of circular economic systems at the mesolevel.

El proceso para establecer una identificación odontológica inequívoca se sustenta en la recuperación de la mayor cantidad posible de información post mortem, y su posterior cotejo con aquellos registros ante mortem de la víctima.

Los dientes son tejidos del cuerpo humano con una elevada resistencia en su estructura, lo que les permite tolerar el embate de los efectos ambientales como el fuego, la desecación, la descomposición o la inmersión prolongada. En la mayoría de los desastres naturales, y también en los provocados por el hombre, los registros odontológicos pueden contribuir para identificar cuerpos que sería irreconocibles aplicando metodologías tradicionales. En cadáveres quemados o carbonizados, resulta imperativo conservar la evidencia odontológica recuperada, para evitar que su manipulación pueda desvirtuarla e incluso destruirla; por eso se suele fijar y estabilizar antes de ser transportada. Los recursos imagenológicos constituyen una sólida estrategia de perennización de evidencia, los cuales pueden ser complementados por fotografías y toma de impresiones. El presente artículo revisa varios estudios sobre restos dentales, materiales de obturación y aparatos protésicos quemados o carbonizados, haciendo énfasis sobre su importancia en el proceso de identificación humana.

Palabras clave: Cuerpos carbonizados, diente, identificación humana, materiales de obturación, odontología forense, restauraciones protésicas.

MODELING ENTREPRENEURIAL INVESTMENT DECISIONS IN THE CYBERSECURITY SPHERE UNDER AMBIGUITY
Authors: Grigoryan A.H.
Published: April 2023

Most economic decisions are made under uncertainty, and decision-makers, particularly entrepreneurs are conscious of external factors that affect their decisions yet are out of their control. However, making the best predictions, these factors or variables will determine the effectiveness of their decisions, which are also influenced by political, environmental, technological and other developments during the course of the investment. In this context, given the high-level uncertainty in the cyber environment and the stochastic nature of cyber threats, it is essential to analyze the uncertain and unpredictable market conditions, study the factors, affecting irreversible investments and define the optimal timing of investment decisions. The standard investment models presuppose that the entrepreneur has an extreme aversion to uncertainty, i.e., mostly considering the worst-case scenarios without ambiguity. This article presents an entrepreneurial investment decision-making model and demonstrates the significance of an entrepreneur's attitude towards Knightian uncertainty (ambiguity) when making investment decisions in the field of cyber security. The model introduces both complete ambiguity-aversion and ambiguity-loving cases․ The numerical example demonstrates the effects of changes in the perceived level of ambiguity and the entrepreneur’s attitude toward ambiguity on the expected value of an investment project. Accordingly, the entrepreneur invests if and only if the expected profit level exceeds the critical level of current profits (threshold), otherwise the investment will not be undertaken.
АВТОМАТИЗАЦИЯ РАЗРАБОТКИ БИЗНЕС-МОДЕЛИ И МОДЕЛИ ОЦЕНКИ НАДЕЖНОСТИ КОММЕРЧЕСКОГО БАНКА
Authors: Хачатрян А.С. , Аветисян К.Р.
Published: April 2023

В рамках настоящей работы разработана бизнес-модель с соответствующими подразделами, основанная на методологии “КАНВАС”, методах сбора, моделирования и автоматизированной обработки многообъемных данных, основах банковского дела и анализа. Разработанная модель описывает процесс создания банком соответствующих ценностей, представляет цели и пути их реализации. На начальном этапе разработки бизнес-модели в качестве конкурентов рассматривались
коммерческие банки Республики Армения, изучались их деятельность и банковский рынок РА.
Путем изучения и анализа многообъемных данных о рынке банковских клиентов определены ожидания клиентов, готовность платить, потребности, запросы и спрос. На основе результатов исследования посредством применения основ математического моделирования, принятия решений, оптимизации и автоматизации разработана наилучшая бизнес-модель по следующим 9-ти основным пунктам: сегментация клиентов, ценностное предложение, распределительные каналы,
отношения с клиентами, потоки доходов, управление затратами, основные ресурсы,
ключевые операции, сотрудничество. При этом основной упор был сделан на разработку автоматизированных контактных систем и вспомогательных автоматизированных систем принятия решений. Управление потоками доходов ирасходов осуществлялось путем разработки модели одновременного управления активами и пассивами (основными ресурсами), целевой функцией которой является оптимизация чистой прибыли в условиях налагаемых Центральным банком ограничений и внутренних ограничений банка. В этой части бизнес-модели описаны наиболее важные действия, которые необходимо предпринять для достижения успеха.
Обобщенная оценка деятельности коммерческих банков и рейтингование банка осуществляются по предложенной в настоящей работе новой модели оценки надежности, разработка которой была обоснована разработкой математической модели анализа многообъемных данных и прогнозирования.
МАТРИЦЫ КОЭФФИЦИЕНТОВ ОШИБОК СИСТЕМ УПРАВЛЕНИЯ БЕСПИЛОТНЫМИ ЛЕТАТЕЛЬНЫМИ АППАРАТАМИ С ПИДРЕГУЛЯТОРАМИ

Published: April 2023

В настоящее время многороторные беспилотные летательные аппараты (БПЛА) имеют широкое применение в различных военных и гражданских областях, включая спасательные работы, мониторинг движения транспорта, определение очагов пожаров в лесах, контроль технического состояния зданий, дорог и железнодорожных путей, проведение сельскохозяйственных работ, геологические исследования.
Вопросам разработки систем управления БПЛА посвящено большое число работ. Однако в этих работах основное внимание уделяется задаче обеспечения устойчивости на основе современных методов теории автоматического управления, включая адаптивное и оптимальное управление, управление на основе нечеткой логики (fuzzy control), робастное управление и т.д. Вместе с тем относительно мало внимания уделено различным аспектам исследования динамической точности систем управления БПЛА при различных внешних управляющих и возмущающих воздействиях, имеющих как детерминированный, так и случайный характер. При этом особо важное значение имеют вопросы исследования точности БПЛА при возможной частичной потере эффективности моторов. Дело в том, что указанная потеря эффективности приводит к тому, что независимые в идеальном случае каналы управления БПЛА по каналам углов крена, тангажа, рыскания, а также каналы управления высотой полета оказываются взаимосвязанными. Поэтому в подобных случаях анализ динамической точности системы управления БПЛА следует проводить на основе методов теории многосвязного управления.
В работе выведены аналитические формулы для матриц коэффициентов ошибок многороторных БПЛА с ПИД-регуляторами. Полученные выражения позволяют исследовать точность систем управления БПЛА при частичной потере эффективности моторов в случае детерминированных внешних управляющих воздействий, заданных в виде степенных полиномов. Приведен числовой пример расчета матриц коэффициентов ошибок для квадрокоптера.
КВАЗИТОЧНОЕ ПРИБЛИЖЕНИЕ ДЛЯ ОПИСАНИЯ ИНТЕРФЕРЕНЦИОННОГО ПОЛЯ ДВУХ КОГЕРЕНТНЫХ ИСТОЧНИКОВ

Рассматривается задача приближенного описания волнового поля в так называемых ближней, средней и дальней зонах наблюдения. Показано, что применимость того или иного приближения обусловлена значением так называемого волнового параметра. Получена зависимость волнового параметра от продольных и поперечных пространственных параметров задачи. Отмечено, что, как правило, при фиксированном значении поперечного пространственного параметра, когда изменение волнового параметра обусловлено изменением продольной дистанции наблюдения, приближенный подход называют приближением по зоне наблюдения. Если же наблюдения проводятся при фиксированном значении продольного пространственного параметра, а изменение волнового параметра связано с изменением поперечного параметра, то обычно говорят о приближении по полю.
На примере гармонического сферического поля вводится понятие так называемого квазиточного описания, которое является более точным приближением по сравнению с приближением Френеля. Получены выражения фазы сферического поля в квазиточном приближении, а также в приближениях Френеля и Фраунгофера. Показано, что в квазиточном приближении множество равнофазных точек по поперечному пространственному параметру определяется поверхностью четвертого порядка,
в то время как в картине Френеля сферическая волна выглядит как параболоидная.
Заметим также, что в приближении Фраунгофера сферическая волна становится плоской.
Рассматривается известная задача описания волнового поля интерференционного опыта системы из двух когерентных волновых источников. Показано, что в
отличие от приближения Френеля, где распределение максимумов определяется линейным уравнением, в квазиточном приближении оно определяется кубическим
уравнением. Воспроизведен также ряд известных результатов, относящихся к приближениям Френеля и Фраунгофера.
Assessing the Financial Impact of Mergers on Islamic Banks: A Case Study of Sustainable Finance and Maqasid Approach
Authors: AL-BINALİ Tamy
Published: April 2023

Bank mergers and acquisitions (M&A) have been on the rise globally, particularly in emerging economies where policies aimed at enhancing financial system stability have been driving restructuring in the banking sector. Qatar's M&A market, while comparatively new, has distinct characteristics. A recent study aimed to determine the impact of M&A activity on the financial performance of Barwa Bank (later Dukhan Bank) in Qatar over six years from 2017-2022, covering three years before and three years post-merger. The study found that the bank's liquidity, profitability, solvency, and investment ratios did not vary significantly, suggesting that M&A activity did not significantly affect the bank’s financial performance. Despite these findings, the study provides recommendations for future research and implications for theory and practice in this area. The results are discussed in the light of SDGs and Maqasid al Shariah, and which goals this merger support the most are analyzed. The paper’s discussion is expected to be a guideline for future mergers to be more sustainable toward 2030 goals.

Uso de Redes Neurais Artificiais para classificação de propostas dependentes e independentes em licitações no ramo de óleo e gás
Authors: Silva Costa José Geraldo , Almeida Gustavo Maia , Scárdua Leonardo Azevedo
Published: April 2023

Na última década, investigações do MPF do Brasil expuseram uma rede de cartéis atuando no setor de óleo e gás. Este caso foi considerado o maior da história do setor ocorrido fora dos EUA (DOJ, 2016). Segundo a OCDE (2022, p. 3), Cartéis são a principal ameaça a lei de concorrência e causam um sobrepreço médio de 20% nos mercados afetados (Smuda, 2012). Mesmo sendo tema relevante, não existe ferramenta universalmente aceita para identificação de Cartéis. Este trabalho propõe a construção de uma rede neural artificial — RNA que classifique as propostas recebidas em uma licitação como sendo ou não parte de um cartel, a partir da análise de um conjunto de características destas propostas. Será utilizado como estudo de caso o processo de compras de uma grande empresa do ramo de óleo e gás, sendo os dados obtidos no portal de compras desta empresa e através de aval gerencial. Este trabalho abordará o processo de tratamento dos dados para a construção do dataset, através da definição de metodologia para escolha das características das propostas (feauture engineering) que serão utilizadas no treinamento da RNA, também serão aplicadas técnicas de exploração estatística no intuito de se entender o comportamento das variáveis.

Published: April 2023

processo de formação de ferroligas em fornos a arco submerso requer uso intensivo de energia elétrica, que é convertida em energia térmica dentro do forno, usando eletrodos do tipo Søderberg. O material que alimenta o forno e é usado para formar o eletrodo é chamado de pasta eletródica. Quando a pasta é introduzida no processo, ela é submetida a condições que criam assimetrias que podem afetar a formação do eletrodo e causar sua quebra. Tal situação é difícil de ser detectada pelas equipes operacionais devido ao número de medições de nível realizadas em vários pontos. Diante disso, há interesse em soluções capazes de detectar a perturbação, uma vez que ela tem um impacto negativo na formação dos eletrodos e, consequentemente, na produção de ferro ligas. Nesse contexto, o uso de sistemas especialistas se apresenta como uma alternativa para agregar e estruturar conhecimentos operacionais e inferir a ocorrência de assimetria na pasta com confiança e de forma automática. Considerando isso, o artigo apresenta uma abordagem de sistema especialista difuso para inferir esse risco potencial na formação do eletrodo Søderberg.

Published: April 2023

Background: Microbial keratitis (MK) is caused by bacteria, fungi, and protozoa. It is very important to differentiate between these three causative microorganisms very early as they differ in their treatment, and some of these microorganisms, like Pseudomonas aeurogenosa, may result in eye perforation within 72 hours .The purpose of this study was to evaluate impression cytology smear to be used as a guide for early accurate treatment of cases. This study was conducted on 80 patients suspected of having MK. A corneal smear was taken with impression cytology paper (a non-invasive technique) and transported to the microbiology laboratory for examination. Results: The IC smear examination results were as follows: 30 (37.5%) were Aspergillus fungus, 14 (17.5%) were Acanthamoeba, 15 (18.75%) were Gram-negative bacilli, 4 (5%) were Staphylococci, 1 (1.25%) was Streptococci, 14 (17.5%) were both Gram-negative bacilli and Aspergillus fungus, and 2 (2.5%) were both Staphylococci and Aspergillus fungus. There was no significant difference between the diagnosis of MK by the culture method and the IC smear method. Conclusion: The impression cytology smear can be used as guide for early treatment of MK.

La siguiente investigación se desarrolló en la zona núcleo del área protegida Refugio de Vida Silvestre Puca, ubicada al norte del departamento de Lempira, siguiéndose la metodología de establecimiento de parcelas de monitoreo permanentes en bosques tropicales al azar, considerando, en este sentido aspectos como, caminos utilizados por la población lenca y pendientes no mayores a 50% para el estudio de la estructura y composición arbórea. Se establecieron 23 parcelas de forma circular con un área de 1000 m2 para la medición y registro de variables dasométricas y sistematización de la dinámica de especies arbóreas en el bosque, encontrándose un bosque con una composición florística abundante. El análisis de correlación de los datos dasométricos en RStudio es de 0.80, mostrando una relación positiva de diámetros y alturas. En este bosque húmedo tropical se encontraron 66 especies en 54 géneros distribuidas en 44 familias. La especie con mayor Índice de Valor de Importancia (IVI), fue Liquidambar styraciflua (L.) con un 23.70%. Se aplicó el Índice de Diversidad de Shannon-Wiener/ Weaver siendo este 3.67 y el índice de diversidad de Margalef de 10.55, interpretándose para ambos valores una biodiversidad alta en la zona núcleo del Refugio de Vida Silvestre Puca.

El estudio se desarrolló en el Jardín Botánico y Centro de Investigación Lancetilla (JBL) de la Universidad Nacional de Ciencias Forestales, con el objetivo de estimar la densidad poblacional del Leopardus wiedii mediante la implementación de la metodología de observación directa mediante el foto trampeo con la instalación de cinco (5) trampas cámaras. Los resultados obtenidos mostraron una densidad poblacional relativa de 0.008%, lo que representa que esta especie se encuentra en muy baja densidad en el Jardín Botánico Lancetilla. Los horarios de actividad de las especies faunísticas presa fue entre las 3:00 y 6:00 a.m.; coincidiendo con el foto trampeo obtenido en el tercer muestreo donde se observó el Leopardus wiedii debido a que las especies de las cuáles se alimenta mostraron actividad a estas horas de la madrugada; entre las especies que le sirven de alimento están el Cuniculus paca “tepezcuintle”, Pecari tajacu “chancho de monte”, confirmando que existe una red trófica que lo sustenta y que el JBL sirve de refugio y es importante para su conservación.

Indonesia yang mayoritas penduduknya beragama Islam memiliki potensi yang besar menjadi pusat pengembangan keuangan syariah di tingkat global, termasuk perbankan syariah. Namun perkembangan perbankan syariah sendiri masih relatif kecil. Salah satu permasalahan yang menghambat perkembangan perbankan syariah adalah rendahnya tingkat literasi keuangan syariah masyarakat. Oleh karena itu, perlu dilakukan pelatihan untuk meningkatkan pemahaman perbankan syariah di masyarakat. Agar lebih efektif, pelatihan tersebut sebaiknya ditujukan ke pihak-pihak yang memiliki pengaruh di masyarakat, seperti pengurus masjid. Diharapkan dengan pelatihan tersebut, pemahaman pengurus masjid terkait perbankan syariah dapat meningkat, dan pengurus masjid dapat meneruskan pengetahuan mengenai perbankan syariah ke masyarakat luas. Untuk melaksanakan pelatihan tersebut, tim pengabdian UPN Veteran Jakarta selanjutnya bekerjasama dengan Forum Silaturrahim Takmir Masjid Kementerian/Lembaga dan BUMN untuk mengadakan sosialisasi perbankan syariah bagi pengurus masjid. Metode kegiatan pengabdian ini menggunakan metode ceramah sebagai metode untuk sosialisasi perbankan syariah, yang selanjutnya dilanjutkan dengan sesi tanya jawab. Kedepannya diharapkan pengurus masjid dapat meneruskan pengetahuan mengenai perbankan syariah ke masyarakat luas, sehingga pemahaman perbankan syariah di masyarakat juga meningkat.

Published: April 2023

This study is aimed at evaluating the productivity and financial performance of income-generating projects (IGPs) of a Philippine State University in the Davao Region from 2016-2020. Further, this study uses a descriptive evaluative research design to analyze and interpret data through the total population sampling, wherein all 22 IGPs were subjected to the evaluation. The results reveal net receipts of 28.16 million from 2016-2020; Crop Production was the highest contributor, while the loss of non-agriculture was recorded in 2020 due to the COVID-19 pandemic. The Crop Production of Campus C had the highest profitability in terms of net income earning 9.04 million for the period covered. Their Commercial Stalls Rental had the most favorable performance in terms of return on investment. The same IGP had the quickest ability to recoup its investment. The Gymnasium and Hostel of Campus C took the lowest Return on Investment and recovery rate. Moreover, the financial contribution of budget allocation and utilization of all IGPs was meager for Instruction and Support to Operations, and no budget shares for the areas of Research and Extension. Hence, eight IGPs are for restructuring and expansion; 11 IGPs are for restructuring only, one IGP is for termination, and one IGP is not subject to any decision strategy
Exploring the Philippine Society and Culture in Monkey Folktales
Authors: Tsuji Takashi
Published: April 2023

This paper analyzes the structure and content of Philippine folktales featuring monkeys (hereinafter referred to as “Filipino monkey folktales”) based on a literature review to explore Philippine society and culture. Subsequently, this paper highlights 20 cases of Filipino monkey folktales. These cases are classified: (1) nine villain type, (2) six human-origin type, (3) two prince type, (4) two trickster type, and (5) one demon type. It is observed that 15 out of 20 cases were “villain type” and “human-origin type.” Thus, it can be deduced that Filipino monkey folktales present relatively negative images of monkeys. This depiction reflects the negative aspects of human thinking and behavior, and it is thought that monkey folktales are often told to educate children and maintain social order. In other words, it can be said that monkey folktales are an honest projection of Filipino morals, human relationships, and social norms. For Filipinos, the monkey that appears in folklore is thought to play the role of a mirror, helping them reflect on themselves to ensure that their behavior is socially acceptable; thus, monkey folktales emphasize social norms. Finally, this paper concludes that the reciprocal relationships that Filipinos value the most are social and cultural norms, contrary to the cunning andselfishness exhibited by monkeys in folklore.

Introduction: Fungal prosthetic joint infections, constitute a small portion of all prosthetic infection cases and candida species are the causative agent in the majority of these cases. Most fungal prosthetic joint infections occur after revision arthroplasty.
Case: A 72-year-old male patient, underwent total knee prosthesis operation for the right knee due to gonarthrosis. About 5 months later, he was hospitalized and treated due to bacterial prosthesis infection. 8 days after discharge, he applied again with the complaints of swelling, pain, temperature increase and redness in the right knee. He was hospitalized again due to prosthesis infection. Antifungal treatment was started for the patient due to the growth of Candida albicans in the knee joint. A total of 2.5 months of antifungal therapy was given. The patient, who recovered without any problems, continues to follow up in the outpatient clinic.
Discussion: In this case report, we wanted to emphasize that in the presence of risk factors in prosthesis infection, we should not forget that the cause may also be fungus, that culture should be taken during the operation and that effective and long-term antifungal treatment should be given in fungal-related prosthesis infections.
