Authors: Aygün Olgu , Gökdemir Özden , Küçükerdem Halime Seda , Bulut Batur Ülkü , Özçakar Nilgün
Published: May 2023

Objective: Violence has recently increased in almost every facet of life, but more noticeable in workplaces. Doctors and other healthcare professionals are among the most frequently targeted and victimized professionals. Healthcare professionals are in danger due to multiple types of violence that can occur in healthcare institutions, resulting from patients, patients' family, or anyone else; threatening conduct, verbal threats, financial abuse, physical abuse, and sexual assault. The current study aims to understand how patients perceive the violence encountered by healthcare workers and to clarify whether there was or wasn't a connection between the participants' ideas and their levels of aggression. Finding out what the patients believe about violence against doctors is important to create action plans to implement these attitudes in a non-violent way.
Method: The volunteers who applied to Family Health Centers by any reason were required to complete a survey that asked them questions about their demographics, the subject, and the State Trait Anger Scale (STAS). According to the research hypothesis and analysis method, the sample size analysis in the G*Power program determined that a total of 305 participants were the target population for the study.
Results: This study was conducted with  351 women, 456 participants in total. To “approve of violence” men were 1.41 times more likely than women ,  aged “≤31.5 years” were 2.227 times more likely than those aged “>31.5 years.” and the unemployed were 2.74 times more likely than the employed.  The results of the “Phi and Cramer’s V” Test, which indicate the level of correlation between two variables, revealed a significant correlation between “Attributing Violence to Illness” and “Recourse to Violence in Healthcare” (Phi = 0.163, p < 0.001).
Conclusion: The results of our study extensively reveal groups with potential risks and associated parameters, and thus can shed light on measures and counselling services to be taken to address the issue.

This research paper aims to present the state of establishments and workers in times of COVID-19 pandemic; discuss the implication of the COVID-19 Adjustment Measures Program (CAMP) under the Bayanihan 1; and make recommendation for improvement in the implementation of CAMP to the Department of Labor and Employment. When the national government imposed a nationwide enhance community quarantine or lockdown on March 16, 2020, majority of business establishments resorted to temporary closures or flexible working arrangements. The implementation of the said lockdown caused the displacement of establishments and workers. There are 9,519 establishments with 261,828 workers affected due to COVID 19 in Central Visayas. Displacement was either establishment implemented flexible work arrangement or resorted to temporary closures. Majority of the displacement came from temporary closures with 6,661 affected establishments (70%) and 150,825 affected workers (58%). Most affected establishments belong to Accommodation and Food Service Activities while most affected workers belong to Manufacturing. Mostly, micro and small size businesses were affected of this pandemic which is found in the Tri-Cities of Cebu, Mandaue, and Lapu-Lapu being the center of commerce in Central Visayas. The Department of Labor and Employment being the implementing arm of the National Government in the field of labor and employment made a timely response thru the COVID-19 Adjustment Measures Program (CAMP).

Published: May 2023

Theoretical principles and regularities are the basis of the development of technological systems in construction. The technology of building and construction is a universal set, which is described by a large number of construction technologies. The latter, in turn, consist of a system of knowledge about the organization of work, structure, methods and ways of performing construction processes, mechanization and quality of work.Production building systems, as a class of functional systems, are created and designed to implement certain tasks, which can be specialized (one task) or multifunctional (several tasks). Multifunctional technological systems are considered in the theories of research operations for the implementation of production building systems of various levels and purposes, as well as system engineering, decision-making methods and optimization.The result of the formation of such systems is the final useful result, which is achieved through interaction and, accordingly, the mutual influence of its participants. Complex systems divide subsystems in order to optimize their elements by formalizing design procedures and create a method for designing multifunctional systems.The system in the form of a construction process has its own structure with a corresponding hierarchy - subordination of its elements with a multi-level structure. The complexity of construction processes determines the level of its structure.Implementation of technological systems through various transformations of labor objects into labor products. The change in the properties of the transformation object takes place in technological processes by the implementation of relevant subprocesses and operations.A flexible approach to the design of multifunctional technological systems is possible when using the universal capabilities of construction and road machines by equipping them with additional interchangeable working bodies

Authors: Постернак І. М. , Постернак С. О. , Постернак О. C.
Published: May 2023

The modern world market is a complex system of interactions between commodity producers, financial and credit, exchange and state institutions, the basis of which is the phenomenon called the large joint-stock corporation. The principle of corporations is the principle of contemporary urban communities: their members, paying taxes to the king or lord, form an association that can protect their common interest. The period of the most intensive formation of corporations (associations) in architectural and construction production is considered – the period of Gothic architecture (individual elements – the end of the 11th...12th centuries; widespread use – the 13th...15th centuries). In particular, it is considered how this architecture was created, the sources of its origin are indicated, as well as the circumstances that caused its spread. For this, Gothic architecture itself was considered from the standpoint of: social orientation (city communities and cathedrals); position of the architect and workers; methods of payment. A comparative SWOT analysis (strength; weakness; opportunity; probable threats) of corporations of the Gothic period and modern times has been developed. In the process of forming plans for the social and economic development of large cities, a situation arises more and more often, when increasing the efficiency of resource use requires not only a concentration of efforts, but also new progressive forms of production organization. We propose to create in the urban reconstruction of the city of Odessa "Corporate scientific and technical complex of urban energy reconstruction "CSTC T-PPR" as an innovative organizational structure that uses in practice the accumulated scientific and technical potential for the reconstruction of the buildings of the historical development of Odessa according to energy efficiency standards.

На даний час логістика набула широкого розповсюдження у багатьох сферах бізнесу. Компанії почали розуміти, що на ринку споживача одним із способів досягнення переваг є формування добре функціонуючого ланцюга постачать та якісне управління ним. Це створило попит на різного роду логістичні послуги, що привело до появи широкого кола логістичних посередників – постачальників транспортно-логістичних послуг, котрі забезпечують інтеграційні процеси у транспортних та сполучених з ними виробничих і складських системах. Кожен із таких постачальників має власний функціонал та забезпечує певний рівень сервісу, що дає компаніям-клієнтам гнучкість у виборі як рівня обслуговування, так і тарифів. За комплексом надаваних послуг логістичних посередників традиційно ділять на 1PL, 2PL, 3PL, 4PL та 5 PL, але наявність таких трендів, як цифровізація логістичних процесів, впровадження у них штучного інтелекту, Інтернету речей, розумних пристроїв спричинила появу таких концептуальних рівнів логістичних посередників, як 6PL, 7PL, 8PL, 9PL та 10PL, котрі поки не є реальністю, хоча приклади надання їх потенційно можливих послуг вже можна спостерігати на практиці. Окрім цього, існує модифікація класифікації PL-посередників, котра враховує види транспорту, задіяного у перевезеннях, поряд із хронологічним місцем логістичних процесів.
Така розвиненість ринку логістичних послуг подекуди призводить до труднощів у виборі логістичного посередника. На цей вибір впливає багато взаємопов’язаних факторів, серед яких обізнаність та чітке розуміння функціоналу посередника. В даній роботі представлений аналіз можливостей сучасних постачальників транспортно-логістичних послуг та їх класифікація. Результати даного аналізу полегшать компаніям-клієнтам ідентифікувати тип постачальника та зробити обґрунтований вибір залежно від своїх потреб.

The Semiotic Paradigm for Deconstructing Event Design and Meaning
Authors: Viol Maren , Todd Louise , Anastasiadou Constantia
Published: May 2023

Festivals and events convey a range of historical, political, social, and cultural signs and meanings; however, there remains limited methodological guidance for understanding these. This article proposes semiotics as a valuable yet underappreciated and underutilized approach in contemporary
event studies and design. In contending the value of semiotics to deconstruct the layers of meanings of festivals and events, this paper builds on the semiotic paradigm first proposed by Echtner in 1999 in a tourism marketing context. Drawing from two empirical studies, the article provides
a framework for the application of semiotics to deconstruct layers of meaning communicated both at and by festivals and events. In making this methodological contribution to the field of event studies, the article also highlights additional potential benefits of semiotics and the adoption
of a design perspective in event management practice.

У доповіді розкрито сутність поняття «національна і громадянська ідентифікація» з точки зору педагогіки і психології, обґрунтовано важливість її формування у молоді. Визначено важливу роль і значний потенціал історичної і громадянської освіти у формуванні національної ідентичності учнів і учениць закладів середньої освіти. Реалізація цього потенціалу потребує змін у змісті шкільної історичної і громадянської освіти, зокрема видалення з програм і підручників наративів, що містять російські маніпуляції історією України, посилення ролі національного переможного міфу, акцентування на фактах щодо європейської інтеграції України і важливості цих процесів. Методика навчання історії і громадянської освіти, що сприяє формуванню української національної ідентичності, має базуватися на активному навчанні. Свідома національна ідентичність формується, якщо історичні знання є результатом самостійної роботи учнів з джерелами у процесі дослідження, наприклад, локальної чи усної історії або проєктної роботи. Така діяльність на відповідному історичному чи громадянознавчому змісті дає змогу індивіду зробити власний вибір щодо приналежності до соціальної групи. Відповідні вказівки й рекомендації для вчителів мають містити як підручники з історії, так і навчальні та методичні посібники для різних класів.
FORMULA FOR A LOWER BOUND FOR THE FIRST NATURAL FREQUENCY OF A TRIHEDRAL TOWER TRUSS.
Authors:   National Research University ", Kirsanov M.N. ,   MPEI", Maslov A.N. ,   National Research University "MPEI"
Published: May 2023

A scheme of a statically determinate tower-type spatial truss is proposed. Three lateral faces of the structure have double diagonal lattices, from below the truss rests on six racks and three additional horizontal lateral braces. The problem of the first natural frequency of free oscillations of the structure is solved. The inertial properties of the truss are modeled by the masses in its nodes. Each mass has two horizontal degrees of freedom. To obtain an analytical expression for the dependence of the lower limit of the oscillation frequency on the number of panels, the approximate Dunkerley method is used. The forces in the truss rods are found from the solution of the system of equilibrium equations for the nodes. The matrix of the system of equations is compiled in the Maple computer mathematics system. The rigidity of the structure is determined using the Mohr integral. A series of solutions obtained for a different number of panels is generalized to an arbitrary case by induction. For sequences of coefficients in the solution, linear recurrent equations are compiled and solved. The analytical solution is compared with the numerical solution of the problem of the vibration spectrum of the structure. It is shown that the first frequency of the spectrum is higher than the analytical estimate by no more than 30%. The accuracy of the estimate depends to a greater extent on the number of panels. As the number of panels increases, the accuracy of the resulting estimate increases. A trusses with only an even number of panels are considered. It is noticed that with an odd number of panels, the determinant of the system of equilibrium equations of nodes vanishes, which indicates the kinematic degeneration of the structure.

According to Russian standards calculating bridges is made only for the action of a strong (maximum design) earthquake with a frequency of once every 500-5000 years. In the whole world practice there is a transition to multi-level designing, which considers several structure limit states and the corresponding design actions. The paper discusses the features of such transition in relation to bridges, with the whole range of issues related to such calculations being described. These issues include specifying limit states, specifying the level of design action, setting load combinations and design schemes for bridges, and taking into account damping in bridge elements. The developed proposals require setting the allowable repeatability of certain limit states and are based on the instrumental part of the current the seismic scale standard.
LONGITUDINAL BENDING OF A WEIGHTY HORIZONTAL ROD ON A RIGID BASE.
Authors:   236039, Kaliningrad, Serpukhovskaya str., 40, Russia, Dorogov Y.I.
Published: May 2023

The loss of stability of a heavy horizontal rod on a rigid base is investigated. The differential equation of the angle of inclination of the curved axis of the rod is obtained using the exact expression of curvature. Various cases of conditions for fixing the ends of the rod are considered. From the possible forms of equilibrium of the rod, those are selected that satisfy the condition of equality of the compressive force work and the sum of elastic and gravitational energies accumulated by the rod. The curved shape of the equilibrium is determined by the maximum angle of deviation of the axis of the rod, which increases with increasing weight of the rod and does not depend on the geometric characteristics of its cross-section.
THE RITZ METHOD IN NONLINEAR CALCULATIONS OF SINGLE-SPAN REINFORCED CONCRETE BEAMS.
Authors:   Belarusian National Technical University, Bosakov S.V. , Kozunova O.V. ,   Belarusian National Technical University
Published: May 2023

The paper considers the calculations of single-span reinforced concrete bent beams, taking into account the nonlinear relationship between stresses and strains. Deflections of beams according to the Ritz method are given as a series of trigonometric functions with undetermined coefficients. Nonlinearity is taken into account by the "moment-curvature" dependence in the form of a cubic parabola. The functional of the total energy of the beam and the load acting on it has a non-linear form with respect to indefinite coefficients, which are found with the help of a computer mathematics package from the condition of the minimum of this functional. Two examples are given for a statically determinate reinforced concrete articulated beam under the action of a uniformly distributed load and a statically indefinite reinforced concrete beam under the action of a concentrated force.

The use of sorbents based on titanium(IV) oxohydroxophosphates for deep purification of liquid radioactive waste of complex chemical composition from Ag(I) and Sb(III) ions is shown to be promising. It has been established that Ag(I) cations are effectively extracted in an alkaline medium, Sb(III) cations - in an acidic region as a result of ionic substitution of H+ hydrophosphate groups for metal cations. Since Sb(III) is present in the anionic form in an alkaline medium, the Sb(III) anions are extracted as a result of ion exchange for the OH--groups of the sorption matrix.
