Published: June 2023

The economic growth of a region in Indonesia is strongly influenced by road and bridge infrastructure. The problem is to design the optimal configuration of the rise-span ratio of the tied arch bridge. This problem must be studied further due to the maximum load combination according to SNI 1725:2016 and SNI 2833:2016. This study aims to understand the effect of rise-span ratio on deformation, natural frequency, magnitude of seismic forces, internal forces and optimum rise-span ratio on a tied arch bridge. This is based on previous research that neglecting the rise-span ratio affects the behavior of the structure as a whole, this needs to be studied according to the location where the bridge is built, because there is an influence from the seismic force response spectrum. The loading given is in accordance with SNI 1725:2016 and SNI 2833:2016. Modeling and structural analysis using Midas Civil software.

Relevance. Victims’ own negligence is a main cause of injuries among the EMERCOM of Russia officers.The objective is to analyze occupational injury scenarios caused by ‘victims’ own negligence’ among the Federal Fire Service (FFS) officers and workers of the EMERCOM of Russia within 2010 to 2021 timespan.Methods. The study examined 10,000 fire service officers to analyze the incidence of occupational injuries due to ‘victims’ own negligence within 2010 to 2021, depending on the injury-associated activity, patient’s position, age, type of injury, weekday and month of injury. We calculated arithmetic average values and errors (M ± m). By knowing the number of injuries and the number of fire service officers at risk, we calculated the risks of injury for specific occupational scenarios.Results and discussion. The FFS officers of the EMERCOM of Russia are subject to the average annual risk of injury due to victims’ own negligence of (4.49 ± 0.62) ∙ 10–4 injuries / (person ∙ year). The risk of injuries commissioned officers (5.54 ± 0.87) ∙ 10–4 injuries/(person ∙ year) exceeds that among non-commissioned workers (3,14 ± 0,29) ∙ 10–4 (injuries/person ∙ year). Over 12 years, the incidence of injuries saw a 2.7-fold decrease among commissioned officers and a 1.4-fold decrease among non-commissioned workers. The share of injuries due to ‘victims’ own negligence’ stood at 36 % of the total number of occupational injuries among fire service officers.Conclusion. The analysis of injury scenarios due to ‘victims’ own negligence’ among the FFS officers of the EMERCOM of Russia is a contribution to enhance prevention of occupational injuries among firefighters and reduce the death rate in occupational settings.
Data-Driven Approach Toward Airspace Design for Regional Air Mobility Operations in Korea
Authors: Kim Junghyun , Kim Seulki 
Published: June 2023

As the Korean government agencies have recently announced the first official road map for urban air mobility (UAM) with the aim of introducing a new aviation transportation system, many companies in South Korea have initiated projects to design airspace infrastructure for UAM operations at the early stage of development. Given that the agencies tentatively plan to expand UAM to regional air mobility (RAM) operations at the mature stage of development, this research specifically focuses on establishing airspace infrastructure for upcoming RAM operations in South Korea. The proposed methodology leverages three different algorithms: 1) a partitioning-based clustering algorithm for placing vertiport locations, 2) a density-based clustering algorithm for predicting areas of convective weather, and 3) the Latin hypercube sampling-based probabilistic road map (LHS-based PRM) algorithm for generating an adaptive airspace network. The resulting airspace, constructed by the proposed methodology, takes into account airspace restriction areas such as prohibited areas or military operation areas. The main contribution of this research is to employ a data-driven approach using machine learning and LHS-based PRM algorithms to dynamically establish airspace infrastructure to be potentially used for upcoming RAM operations in South Korea.
Acoustic Modeling Using the Aeroacoustic Wave Equation Based on Pierce’s Operator

Published: June 2023

The capabilities of an aeroacoustic wave equation based on Pierce’s operator (AWE-PO) for modeling subsonic flow-induced sound and for sound prediction are investigated. The wave equation is applied to an isothermal two-dimensional mixing layer computed by direct numerical simulation. In contrast to a direct numerical simulation, providing the acoustic fluctuations directly, the simulations based on Lighthill’s wave equation and the AWE-PO rely on a hybrid workflow to predict the generated sound field. Special attention is put on the interpretation of the right-hand side of both wave equations. Comparing the terms on the right-hand side in Lighthill’s theory and AWE-PO suggests a source amplitude for AWE-PO that is 90% smaller. This reduction is attributed to the filtering property of the material derivative. Finally, the results of the acoustic far-field pressure are compared. It is shown that the radiated sound field’s directivity, propagation, and convection effects are well captured for both wave equations. The computations using Lighthill’s equation and AWE-PO are found to provide acoustic intensities within 1.8 dB from the reference direct numerical simulation. This error is comparable with the errors reported for Lighthill’s equation in previous studies.

Внимание ученых к обеспечению различных процессов жизнедеятельности человека надлежащей информацией привело к появлению многих определений понятия "информационное обеспечение" в соответствии со сферой исследования, в частности, его трактуют как создание информационных условий функционирования системы, обеспечение необходимой информацией. Исследование понятия "информационное обеспечение" позволило сделать вывод, что его многозначность зависит от сферы применения и научных подходов, которые применяют ученые до его формулировки; соответственно определяются виды информации, информационных ресурсов и процессов. Цель статьи заключается в определении и обосновании составляющих информационного обеспечения НИРС ВУЗОВ, которые удовлетворяли бы их информационные потребности на этапах учебного исследования. Информационное обеспечение НИРС понимаем как целенаправленно подобранную и систематизированную совокупность информации, которая необходима для осуществления учебного исследования, и комплекс соответствующих информационных ресурсов, источников и технологий, обеспечивающие осуществление информационных процессов на этапах исследования.
The attention of scientists to providing various processes of human life with appropriate information has led to the emergence of many definitions of the concept of "information support" in accordance with the field of research, in particular, it is interpreted as creating information conditions for the functioning of the system, providing the necessary information. The study of the concept of "information support" allowed us to conclude that its ambiguity depends on the scope and scientific approaches used by scientists before its formulation; accordingly, the types of information, information resources and processes are determined. The purpose of the article is to identify and substantiate the components of the information support of R&D universities that would satisfy their information needs at the stages of educational research. We understand the information support of R&D as a purposefully selected and systematized set of information that is necessary for the implementation of educational research, and a set of relevant information resources, sources and technologies that ensure the implementation of information processes at the stages of research.
ПСИХОЛОГІЧНИЙ АНАЛІЗ ПРОБЛЕМИ ПСИХОЕМОЦІЙНИХ СТАНІВ ОСОБИСТОСТІ В УМОВАХ СЕПАРАЦІЇ
Authors: Кульчицька Анна , Полікарчик Софія 
Published: June 2023

Мета. У статті розкрито соціально-психологічне явище сепарації, а також особливості психоемоційних станів особистості студента в умовах сепарації. Мета полягала у дослідженні особливостей психоемоційних станів особистості в умовах сепарації.
Методи. Для досягнення поставлених цілей були використані: методика дослідження психологічної сепарації від батьків в юнацькому віці Дж. Хофмана (адаптація А. Широка); методика самооцінки емоційного стану Уессмана-Рікса; опитувальник дитяче-батьківських емоційних взаємовідносин (ОДБЕВ) Є.І. Захарової; методика «Стратегії сімейного виховання» С. С. Степанова в модифікації І. І. Махоніної; кореляційний аналіз.
Результати. Дослідження психологічної незалежності показало, що переважна більшість опитаних проявили середній рівень сформованості «незалежності» у стосунках з батьками. Однак, третина респондентів - мають більшу незалежність від матері, ніж від батька. В опитаних найшвидше формуються емоційна незалежність та незалежність у ставленнях. Високий рівень загального показника емоційного стану, притаманний половині опитаних, чверть студентів мають низький рівень, решті притаманний середні рівень показника. Дослідження дитячо-батьківських емоційних взаємовідносин стверджує, що емоційні взаємовідносини між батьками і дітьми знаходяться в межах норми. В загальному показники вищі критеріальних. Однак, такі шкали як «емпатія», «надання емоційної підтримки», у більшості діагностованих мають показники нижче критеріального, що свідчить про дефіцитарність відповідної характеристики. Результати дослідження стилю виховання в сім’ї демонструють, що переважаючим є демократичний стиль виховання, водночас, індиферентний стиль виховання проявився найменше. Кореляційний аналіз допоміг виявити прямий зв’язок між стосунками з батьками та самооцінкою емоційного стану, з емоційними взаємовідносинами дітей і батьків, а також із стратегією виховання в сім’ї. Емоційна сфера є чинником успішної чи неуспішної сепарації – чим вищий рівень енергійності в діагностованих, тим більше приємних почуттів виникає у батьків під час взаємодії і навпаки.
Висновки. Психоемоційні стани особистості мають взаємозв’язок з успішністю перебігу сепараційних процесів у юнацько-батьківських відносинах. Чинниками успішної сепарації вважаємо: особливості психологічної незалежності; емоційні стани як у батьків, так і в юнаків; дитяче-батьківські емоційні взаємовідносини; стиль виховання в сім’ї.

Published: June 2023

Purpose. The purpose is to identify widespread life landscapes with their value-sense and vector configuration in the context of war.
Methods. The method used is the conceptualization of war-experience in 169 Ukrainian civilians’ narratives with a descriptive, interpretative analysis, and multiple correspondence analysis (MCA) conducted. The clarification of values, communication, professional activity, plans regarding future allowed to determine common landscapes.
Results. The three main types of life landscapes were defined: the landscape of service with the dominant context of volunteering, selfless help to the army (27,8%), the existential landscape with the dominant context of suffering, surviving (24,3 %) and the landscape of care with the dominant context of saving family, partnership (23,7 %). The less common is the landscape of self-development with the context of personal growth and the societal landscape with economic and political contexts. The existential landscape is the most common among young respondents; the landscape of care – among the group of early maturity; the landscape of service – among the group of middle and late maturity. Gender differences are as follows: in women, the landscapes of service, care, and existential are almost equally represented; in men, the landscape of service is the most popular; next, come the existential and societal landscapes. Dimensions of activity-passivity and narrowness-broadness were found out to be the most significant in multiple correspondence analysis.
Conclusions. The study offers an explanation of war experience through the prism of personal life landscapes. The determination of widespread landscapes with age and gender characteristics enables the targeted development of social and psychological support for victims.
