Published: July 2023

Presenteeism can have negative impacts on employees’ health and organizational productivity. It occurs more often among occupations with high attendance demands, such as healthcare professionals. Information is lacking regarding the extent to which presenteeism differs between disciplines and settings in the health sector and what the reasons are for presenteeism as well as influencing factors. This study used cross-sectional data on 15,185 healthcare professionals (nursing staff, midwives, physicians, medical-technical and medical-therapeutic professionals) from various settings (acute care, rehabilitation or psychiatric hospitals, nursing homes and home care organizations). Presenteeism was measured by examining how many days participants had gone to work despite feeling sick during the past 12 months. Kruskal–Wallis was used to test for significant differences between healthcare professions/settings and regression analysis to identify significant predictors of presenteeism. Nursing assistants with a formal education reported the most days of presenteeism in the past 12 months (mean = 4.3, SD = 12.0). Healthcare professionals working in nursing homes reported the most days of presenteeism in the past 12 months (mean = 4.2, SD = 8.7). The majority of healthcare professionals had been present at work while being ill due to a sense of duty (83.7%), followed by consideration for colleagues and/or managers (76.5%). In particular, the psychiatric hospitals (β = 0.139; p < 0.001), nursing homes (β = 0.168; p < 0.001) and home care organizations (β = 0.092; p < 0.001), as well as the language regions of Swiss French (β = − 0.304; p < 0.001) and Italian (β = − 0.154; p < 0.001), were significantly associated with presenteeism. Presenteeism differs between disciplines and settings in the health sector. The reasons for presenteeism and its influencing factors in the health sector are mostly consistent with those in other sectors. Cultural differences should be afforded greater relevance in future presenteeism research.

The obstacle to the industrialization of perovskite solar cells (PSC) technology lies in their stability. This work rationalizes the PSC design with the employment of 2D-MoS2 as the hybrid hole transport layer (HTL). MoS2 was selected due to its unique optoelectronic and mechanical properties that could enhance hole extraction and thus boost the performance and stability of PSC devices. Five concentrations indicated MoS2 nanosheets were directly deposited onto the perovskite layer via the facile spin coating method. The electrochemical exfoliation and liquid exchange methods were demonstrated to obtain the lateral size of MoS2 nanosheets and further discussed their microscopic and spectroscopic characterizations. Remarkably, the optimum thickness and the excellent device increased the stability of the PSC, allowing it to maintain 45% of its degradation percentage ($$\frac{\Delta PCE}{PCE}$$

) for 120 h with high relative humidity (RH = 40–50%) in its vicinity. We observed that lithium-ion can intercalate into the layered MoS2 structure and reduce the interfacial resistance of perovskite and the HTL. Most importantly, the 2D-MoS2 mechanism’s effect on enabling stable and efficient devices by reducing lithium-ion migration in the HTL is demonstrated in this work to validate the great potential of this hybrid structure in PSC applications.

Despite mortality in intensive care units (ICU) being a global public health problem, it is higher in developing countries, including Ethiopia. However, insufficient evidence is established concerning mortality in the ICU and its predictors. This study aimed to assess the magnitude of ICU mortality and its predictors among patients at Tibebe Ghion specialized hospital, Northwest Ethiopia, 2021. A retrospective cross-sectional study was conducted from February 24th, 2019, to January 24th, 2021. Data were collected from medical records by using pretested structured data retrieval checklist. The collected data was entered into Epi-data version 3.1 and analyzed using R version 4.0 software. Descriptive statistics computed. A simple logistic analysis was run (at 95% CI and p-value < 0.05) to identify the determinants for ICU mortality. A total of 568 study participants’ charts were reviewed. The median length of ICU stay was four days. Head trauma and shock were the leading causes of ICU admissions and mortality. The overall mortality rate of the ICU-admitted patients was 29.6% (95% CI: 26%, 33%). Admission in 2020 (AOR = 0.51; 95%CI: 0.31, 0.85), having altered mentation (AOR = 13.44; 95%CI: 5.77, 31.27), mechanical ventilation required at admission (AOR = 4.11; 95%CI: 2.63, 6.43), and stayed < 5 days in the ICU (AOR = 3.74; 95%CI: 2.31, 6.06) were significantly associated with ICU mortality. The magnitude of the ICU mortality rate was moderate. Years of admission, altered mentation, mechanical ventilation required at admission, and days of stay in the ICU were the predictors for ICU mortality. This finding underscores the importance of interventions to reduce ICU mortality.

Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These pulsars alternate between a radio pulsar state and an active low-luminosity X-ray disc state. During the active state, these sources exhibit two distinct emission modes (high and low) that alternate unpredictably, abruptly, and incessantly. X-ray to optical pulsations are observed only during the high mode. The root cause of this puzzling behaviour remains elusive. This paper presents the results of the most extensive multi-wavelength campaign ever conducted on the transitional pulsar prototype, PSR J1023+0038, covering from the radio to X-rays. The campaign was carried out over two nights in June 2021 and involved 12 different telescopes and instruments, including XMM-Newton, HST, VLT/FORS2 (in polarimetric mode), ALMA, VLA, and FAST. By modelling the broadband spectral energy distributions in both emission modes, we show that the mode switches are caused by changes in the innermost region of the accretion disc. These changes trigger the emission of discrete mass ejections, which occur on top of a compact jet, as testified by the detection of at least one short-duration millimetre flare with ALMA at the high-to-low mode switch. The pulsar is subsequently re-enshrouded, completing our picture of the mode switches.

Authors: Yurevna Yaskova Natalya
Published: July 2023

The environmental agenda of global development, temporarily suspended by the sanctions regime due to objective circumstances, cannot be lifted, it needs to be reset, taking into account the logistical, technological and investment constraints that have arisen. Possibly less ambitious and locally focused eco-projects are required. The analysis of the experience of eco-cities recognized as the best has shown that the effectiveness of the integrated use of cleaning and recycling technologies, methods of reproduction and consumption of energy resources, technologies of transportation and organization of public spaces, smart regulation of the housing and communal system, etc. it is sufficient to compensate for the impact of rising cost factors. At the same time, the frontal implementation of eco-technologies in practice is hindered by political instability, low investment activity, and the lack of development of technologies, especially bearing in mind the confirmation of the effectiveness of their use in practice. Taking into account the practical results and the identified problems, the author suggests using an exposition mechanism for promoting eco-projects with the possibility of iterative, as soon as ready, expansion of innovative technological content of projects.

Methodological principles of forming a mechanism for assessing environmental damage from the functioning and development of industrial real estate within the boundaries of the urban environment
Authors: Grabovy Petr , Galishnikov Ilya , Volkov Roman
Published: July 2023

It is not possible to imagine the implementation of investment and construction projects for industrial purposes in isolation from the environment. During the construction and further operation of enterprises, it is necessary to remember the close relationship between nature and man and plan the processes of waste disposal from harmful substances. In pursuit of profit, management often forgets about air and water purification measures, which causes deterioration of the natural environment around the enterprise, complaints from residents, loss of business reputation, and often financial losses due to the need to eliminate the consequences of emissions. Thus, during the construction of industrial facilities, an important task is not only the calculation of profits from operation, but also environmental protection measures, which must necessarily be carried out by enterprises. The growth of the country's economy largely depends on the growth of gross domestic product (GDP). In 1934, when this indicator was first introduced, it was most often used to understand how much the country is ready for hostilities and how many products enterprises can produce to ensure stable functioning. Later, in the 40s, the indicator was associated with the volume of industrial production, since the service sector at that time was poorly developed. And accordingly, the calculation of the GDP indicator was a very necessary mechanism: the growth of GDP per capita from one thousand to 10 thousand. dollars meant a rapid leap in the material well-being of the population.

Published: July 2023

It is known that currently one of the most significant challenges in the field of construction and housing and communal services, is to improve the comfort and affordability of housing, to improve the quality of urban environment. This is also evidenced by the relationship between strategic plans for the period up to 2030 and the activities of the national project “Housing and Urban Environment”. This article analyses the level of citizens’ life quality of the Russian Federation in urban agglomerations and approaches to its assessment. In the framework of the study it has been revealed that nowadays the main indicator for assessing the quality of life is the index of urban environment quality, which consists of 6 indicators assessed according to 6 criteria. The authors decided to also consider the main environmental and economic indicator, expressed as an assessment of damage from environmental pollution, which includes 4 components. Preliminary the results of the conducted research determine the necessity of identifying the most significant criteria (and their sub-criteria) in order to develop an integrated approach to their assessment. As a comprehensive approach, the authors propose a multi-criteria evaluation methodology that includes expert opinion and consideration of weighting coefficients depending on the importance of a particular criterion. Within the framework of this article, the authors propose to test the proposed multi-criteria approach on the most significant space - housing and the surrounding area. The obtained results influence the positive decision to conduct further research for all the spaces included in the current methodology of the urban environment quality index assessment.

Environmentally friendly material for the construction of pile foundations on permafrost
Authors: Stoyanov Igor
Published: July 2023

Modern construction of pile foundations in permafrost conditions includes a cycle of operations: conducting geological and geodesic surveys; developing design and estimate documentation; construction and installation work; monitoring. Six main indicators are considered to determine the organizational and technological reliability of pile foundations for industrial tanks in permafrost soils: environmental performance (EF), intensity (Cf), cost (Cf), innovation (Mf), operational reliability (ORf), quality (Qf). Eco-friendliness depends on the material, the immersion technology, embedding depth, engineering and environmental survey, and other factors. Quality depends on determining the characteristics of the soil, assessing the depth of the hard frozen ground, methods for analyzing the strength characteristics of piles, pile inspection methods, materials, sinking technology, and other factors. The intensity depends on the volume and duration of the work. The duration depends on the depth of the foundation, pile installation technology, climatic conditions, soil characteristics, and other factors. The cost depends on the depth of embedding, immersion technology, material, construction area, the complexity of the project, and other factors. Innovativeness depends on introducing new technologies, resistance to climate change, material, structural changes in piles, and other factors. Operational reliability depends on permafrost soil characteristics, foundation design parameters, material performance characteristics, process parameters, operating conditions, inspection and maintenance, and other factors.

Published: July 2023

The aim of the work is to study the stress-strain state of reinforcing bars during bending and to obtain the appropriate formulas and dependencies to clarify the possible boundaries of the use of mandrels for reinforcement of various classes and diameters. The object of the study are bending bars used as transverse reinforcement in the design of linear reinforced concrete elements. The study determines the possible limits of use for various classes of bars, where the relative deformations of steel do not go beyond the yield strength. A formula is obtained for calculating the possible limiting diameters of mandrels D for various diameters of bent bars d. The limiting diameter of the mandrel depends only on the relative standard elongation of the extreme fiber of the bent bar Graphs of relative elongations of the extreme fiber of the bars are plotted for different diameters of a bent bar made of reinforcement of classes A240, A400, A500S. The calculated values of relative elongations in percent are calculated for plain bars and ribbed bars with diameters from 6 to 28 mm.

On the basis of taking into account global trends and best practices, the task of integrated urban development of urban underground space with the integral use of its main resources and services (not only spatial, but also other: geoenergy, geomaterials, groundwater) is set. Through the prism of the implementation of this "Deep City" model, national peculiarities are investigated and the current situation regarding the effectiveness of the system and documents of standardization (technical regulation) in relation to such topical formats of urban renewal as a model of integrated development (renovation) of the territory is evaluated. The main Sets of rules (as well as their current draft versions of such documents) that establish or should establish appropriate requirements for the implementation of this segment of urban development activities are identified and analyzed. The analysis was carried out in conjunction with the relevant areas of improvement of legal regulation. The results of the analysis showed the presence of systemic standardization defects (primarily gaps) and identified their causes. On this basis, general proposals are given to eliminate the identified defects, as well as general and specific proposals for the development (revision) of standardization documents. Such recommendations can be useful to the developer, the state customer, the executor of the draft Code of Rules and National Standards, as well as a representative of the expert community.

Published: July 2023

The study aims to reveal factors facilitating healthy lifestyle of modern students. This article presents the findings obtained in the case study “Our health” carried out in Moscow bi-region in October 2019. A group of researchers from Plekhanov Russian University of Economics surveyed students using online questionnaire method (N=2600). According to the findings, the widely-recognized health promotion activities are regular exercise, Sport classes at university, mental exercise, walks in the fresh air, listening to music. Some unconventional activities, for instance, walking upstairs, dancing and spending time on a hobby, also gained approval. The respondents showed little concern with oriental health-promoting activities and healing methods. Basically, most students prefer dynamic exercise to static one. Young adults rarely visit doctors or use medication. The respondents are not concerned much about their mental health, and thus, rarely apply for professional psychological help. The majority of the respondents value long and steady relations and speak against casual sexual relations, which proves their awareness on sexually transmitted disease prevention. In conclusion, we need to draw attention to certain discrepancy between intended value-based orientation towards healthy lifestyle and its translation into action.

Published: July 2023

On November 6th, 2021, the first light rail transit (LRT) began operating in Vietnam after a decade of construction. This project aimed to alleviate traffic congestion in the road network of the Hanoi capital. However, despite the deployment of the transit service, passenger volume remains under-capacity, raising questions about how to encourage people, particularly young individuals, to use the new public transit. Hence, this study investigated students’ behavior in choosing the LRT as a means of transport. Statistical analysis of the questionnaire survey showed that the satisfaction level was the dominant factor affecting the mode choices of students. Besides, distance from home to school and LRT station accessibility significantly influenced students’ traveling behavior. These findings provide fundamental insight into young Vietnamese individuals’ behavior regarding a new transit service. We believe these outcomes would help support policy-makers and service providers in improving the LRT projects’ efficiency.

Published: July 2023

Currently, the design of bus stops is an urgent task of both public network design and urban planning. In recent decades, the main passenger volumes in cities of the Russian Federation are served by bus routes. There is a very high public transport traffic volume on the streets of cities without metro, which can exceed 100 buses/hour. In these cases, there are significant volumes of arrivals at bus stops, which cause queues of buses, additional delays and a decrease in commercial speed. In this regard, a study of the bus stops performance was done in different cities of the Russian Federation. Particular attention is paid to the functioning of far-side bus stops of the signalized intersections, which are characterized by uneven arrival of buses and trolley buses, caused by the influence of the signalized intersections. The performed study allowed to obtain: a representative sample of statistical data on the functioning of far-side bus stop of the signalized intersections. The dependences of the characteristics of the functioning of bus stops as a function of public transport traffic volume, the number of bus routes, as well as the characteristics of the signalized intersections. Based on the failure probability the simplified methodology for estimating the required number of loading areas of far-side bus stops of the signalized intersections has been proposed. The obtained data and dependencies can be used for the calculation of bus stops carried out at the stages of urban planning and preliminary design.

Over the past 10 years, transport interchange hubs (TIH) in Russia have turned from projects with a strictly transit purpose into key elements of urban infrastructure modernization, increasingly attracting people's attention and acquiring additional functions. It is worth noting that in the living conditions of a modern metropolis, mobility, speed and ease of movement are the most important criteria for the development of transport infrastructure, and projects to create a TIH, meeting these requirements, give a new impetus to the formation of public spaces where people can receive the necessary services and services without leaving the area of residence. These factors require timely adaptation to the existing situation and the search for new solutions, one of which may be the integration of real estate into the TIH and adjacent territories, which will allow projects to be implemented on more investment-attractive land plots, within walking distance from the metro, MCC, public transport stops. It is assumed that office and shopping centers built in the adjacent territories of the TIH will have a higher demand due to passenger traffic passing through the shopping areas, reducing the time of office users on the road and the advantageous territorial location of the property, which will positively affect the growth of prices for renting and selling these objects and, as a result, on profitability and efficiency of development projects.

In the railway network plan for the period of 2021 – 2030, with a vision to 2050, the Vietnamese Government aims to complete the North – South high-speed railway route – the first phase (from 2025 – 2030) and invest in Hanoi – Vinh and Nha Trang – Ho Chi Minh City routes. In order to realize the above goal, the Ministry of Transport has agreed with the Ministry of Planning and Investment to submit the “Project of investment policy on construction of North – South high-speed railway” to the Politburo in 2023. However, in reality, it is extremely difficult to mobilize enough resources to complete the “super project”. Choosing the right financing mechanism is critical to the success of the project. The article studies the experience of capital mobilization in a number of countries with developed high-speed railway systems or whose economies and societies have many similarities with Vietnam; analyzes achievements and difficulties. Based on the actual conditions of Vietnam, we can draw important lessons and recommend forms of implementation consistent with actual policies and resources, in order to invest on schedule and achieve the results in accordance with the tasks set forth by the Government.
Solutions to improve the attraction of Hai Phong public transport system

Published: July 2023

Public transport is an indispensable demand of all cities in the world. From the 1990s, many cities in Vietnam have installed public transportation networks. Admittedly, the public transportation system is inefficient and has not met its objectives. Hai Phong is a large city in Vietnam whose public transport system still faces many shortcomings. Developed in 2004, the public transport system has only met 1% of people's needs. This study presents the present condition of the bus public transportation system in Hai Phong City and examines the reasons why public transportation does not match people's travel demands. Based on the findings, authors propose solutions and policies to improve the attractiveness of buses to attract people to use public transport services, help develop public transport and safeguard the environment.

The article defines the importance of organizing road traffic in urban transportation systems. The research targets are defined and all its key elements and characteristics are identified. The research target is a segment of the North-Western Chord of Moscow corresponding to Bolshaya Akademicheskay Street in the Koptevo District and limited by Mikhalkovskaya Street and 3rd Nizhnelikhoborskiy Proyezd. The research resulted in a model of a transport system graph for the area under study delineating traffic and pedestrian flows. The model takes into account the points of conflicts in crossing and merging of flows. The research findings became the basis for a mathematical model of traffic in problematic spots of the area under study. Conclusions are made as to the suitability of the findings and their use in the smart city system.

The accumulation of heavy metals (HM) in the leaves of woody plants has been studied on busy municipal highways in North-Eastern (NEAD) and South-Western (SWAD) administrative districts of Moscow. Background contents and their exceeding values for Fe, Sr, Ba, Cr, Cu, Mn, Zn, Bi, Ni, Pb were determined. The study showed that among the dominant deciduous tree species, hanging birch, Norway maple, and small-leaved linden have a high ability to accumulate heavy metals, which are characterized by the accumulation of such elements as Zn, Mn, Sr. According to content of HM in the leaves for the studied territories, an acceptable category of pollution and a greater contribution of the technogenic component is observed in SWAD in comparison with NEAD.
Classification of transport-transfer hubs, taking into account the interaction of modes of transport in cities with million-strong cities
Authors: Terekhova Anna I. , Vlasov Denis N.
Published: July 2023

During the period of active urbanization and the strengthening of the connection of large cities with suburban areas, there is a great need to develop transport systems that connect industrial centers with residential areas, gravitating to them. Transport congestion, the development of rapid off-street transport, the growth of agglomerations, the lack of sufficient parking spaces lead to the need to develop public transport, and as a consequence of the development of transport hubs. In the study, by the method of analysis of variance, the selection of factors affecting the development and formation of transport hubs was carried out. Based on the significant factors, a cluster analysis was carried out to identify groups of TIHs in cities with a population of more than 1 million people. The study is conducted on the example of two cities: Voronezh - 1.06 million people, Ufa - 1.13 million people. As a result, a table with the types of transport-transfer hubs on the basis of interacting modes of transport in cities with a population of more than 1 million people is proposed.

Authors: Topilin Ivan , Konovalova Daria
Published: July 2023

Traffic management, with increasing levels of motorization, is a serious and relevant issue for all major cities and agglomerations in the world. The creation of cooperative intelligent transportation system (C-ITS) is an effective solution to all the problems connected to road management. The current state of development of information systems in the world shows the high level of state interest in creating their own intelligent transport and road systems, as well as the formation of conditions for implementing such technologies on every level of road operation. For fulfilling this purpose, standardization systems of various levels and architectures have been created and developed, but still haven’t been implemented in local traffic safety schemes. The purpose of this article is to review, present, and describe positive outcomes of C-ITS implementation in modern road traffic management. Studies on this matter have shown that the implementation of C-ITS will reduce the number of accidents by 76% and, subsequently, completely eliminate the number of fatal accidents.

The paper evaluates the results of the transport reform in St. Petersburg. It has been established that the current trends in the development of the urban economy in the modern world are being implemented in line with a smart city development strategy, and St. Petersburg is no exception in this regard. It was revealed that the main emphasis in planning the transport reform in St. Petersburg was placed on the systemic nature of its implementation. With this in mind, the authors developed and tested a comprehensive model for evaluating the results of the reform, appealing to the methodology of strategic analysis, taking into account information from open sources. The proposed model was tested on the basis of expert assessments and visualized using heat map tools. As a result, the most significant difficulties faced by the city administration during the implementation of the transport reform were identified, and the need for continuous monitoring (including using sociological survey data) of the model parameters to assess the dynamics of public transport reform was argued. The materials of the paper were tested during a series of round tables held by the St. Petersburg State University in 2022, which were devoted to the strategy of smart city development.
