Intra-firm mobility as a factor in the quality of employees' working life: specifics in the context of economic turbulence
Authors: Kruglov D. V. , Plotnikov V. A. , Reznikova O. S.
Published: January 2025

Relevance. In modern personnel management systems, more and more attention is paid to the principle of human-centeredness. From the standpoint of increasing the return on employees, special attention has been paid to such a complex indicator as the quality of their working life. In this context, an in-depth analysis of the factors influencing it is required, especially taking into account the turbulence in development inherent in the modern Russian economy.

The purpose is development and advancement of theoretical and methodological aspects of the formation and development of the quality of working life.

Objectives: to analyze the concepts of quality of working life; to identify the features of intra-company mobility that affect the increase in employee productivity; to substantiate and develop proposals for improving the quality of working life based on employee mobility within the enterprise.

Methodology. The methods of quantitative and qualitative, monographic and retrospective analysis, methods of comparing economic phenomena and processes, methods of abstraction, generalization of analyzed economic information, as well as specific methods of quality economics and motivation theory were used.

Results. Improving the quality of life, including work life, requires building an effective system of interaction between society, business and the state, which is especially important in the context of economic turbulence. The paper analyzes the concept of quality of work life. The factors of formation of quality of work life are determined. Directions of personnel development in order to stabilize employment are proposed. The theoretical results of the study develop the theory of quality economics and the theory of labor economics. Applied findings of the study can be useful for enterprise management and heads of HR services.

Conclusions. One of the main conditions for the growth of labor productivity is the quality of work life. Planning of mobility within the organization should be carried out on the basis of differentiation of employees depending on the degree of their importance, for which it is recommended to categorize employees into the "center" and "periphery". Such division of personnel allows applying an individual strategy of personnel development in order to stabilize employment. The existing mechanisms of organization, motivation of labor and formation of quality of working life are seriously influenced by external factors, in particular, such a factor is a series of macro shocks of recent years, which caused turbulence in the economy; intra-company mobility is aimed at satisfying the needs of the individual and it can be considered as a factor in improving the quality of working life, including in the conditions of the noted turbulence.
The development of Russian-Iranian trade relations in the context of transition to free trade
Authors: Kozyrev A. S.
Published: January 2025

Relevance. The article examines the development of foreign trade relations between Russia and Iran in the context of transitioning to a free trade regime. The relevance of the topic is driven by the growing importance of economic cooperation between the two countries against the backdrop of geopolitical changes and sanctions pressure from Western states.

The purpose of the study is to identify key trends and factors influencing bilateral trade between the studied countries, as well as the risks associated with Iran's integration into the free trade zone of the Eurasian Economic Union.

The objectives of the research include studying the foreign trade profiles of the two countries, examining the dynamics, structure, and trends of bilateral trade, and identifying the potential for mutual trade between Russia and Iran.

Methodology. The methods used include statistical analysis of time series, calculation and analysis of the export similarity index, and comparative analysis of statistical data on bilateral commodity flows.

The results obtained include the calculation of the export similarity index values for Russia, Iran, and their key trading partners. The index values indicate a high similarity in the exports of Russia and Iran and highlight the risks associated with Iran's integration into the free trade zone of the Eurasian Economic Union due to potential intensification of competition. The analysis of the structure and dynamics of commodity flows showed that the export of goods from Russia to Iran has transformed, with Russian suppliers losing their position in Iran's market of iron, and agricultural products now forming the basis of the export commodity flow. Imports of goods from Iran to Russia also primarily consist of agricultural products. At the same time, there is an observed growth and diversification of imports, facilitated by sanctions isolating both countries from global markets and pushing them towards strengthening bilateral cooperation. The analysis of complementary commodity flows indicates that there is unfulfilled potential for growth in bilateral trade across various industries. Iran's integration into the free trade zone of the Eurasian Economic Union and the removal of trade barriers could serve as a powerful stimulus for the rapid development of trade relations.

The conclusions of the study indicate a slow development of trade relations between Russia and Iran, primarily due to Iran's protectionist policies, currency crisis, low competitiveness of Iranian goods, and underdeveloped infrastructure. However, the intensification of cooperation, including the removal of trade barriers and the development of the "North-South" transport corridor, is contributing to the growth of trade turnover. A significant step has been the establishment of free trade agreements, which have already begun to yield tangible results.
Implementation of the state policy in the field of housing and communal services of the Kursk region
Authors: Kuzmina V. M. , Parkhomchuk M. A. , Levshakova S. R.
Published: January 2025

Relevance. Modern realities are such that society is becoming more and more aware of and realizing its rights to a decent life, among which there is the right to housing as a basic characteristic that further determines the behavior and consciousness of a person. Housing should be safe in the first place, and then affordable, in connection with which we can talk about the need to develop such measures of housing policy in Russia that would reflect the essence of our country as a social state, acting exclusively in the legal field during the implementation of various housing programs with care for the person and citizen of its state.

The purpose is to analyze the implementation of state policy in the field of housing and communal services in the Kursk region on the basis of legislative and statistical data.

Objectives: to characterize the essence, structure and main legislative acts in the field of housing and communal services regulation; to study the effectiveness of the implementation of regional projects in the field of housing and communal services in the Kursk region.

Methodology. In the processing of factual material, traditional scientific approaches were used – dialectical and systemic. The methods of comparison, statistical analysis and ranking were used as research tools.

Results. Currently, housing and communal services perform two functions that are different in meaning and content. The first is a social function that functions as an element of the social protection system of the population, and the second is an economic function, since it provides housing and communal services to the population. The interdependence and opposite orientation of these functions determine the contradictions and problems that arise in social processes with the continuous consumption of living space and utilities.

Conclusions. The main goal of the development of housing and communal services in the Kursk region is to improve the quality and reliability of housing and communal services, improve housing conditions, increase the protection of the housing stock and the level of housing and communal services for citizens in accordance with the current quality standards.
Experimental Study and Kinetic Modeling of Agro-Industrial Wastes for Conversion to Fuel Gas via the Boudouard Reaction
Authors: Vamvuka Despina , Sfakiotakis Stelios , Patlaka Elpida
Published: January 2025

Independent parallel reactions (IPR) and distributed activation energy (DAEM) kinetic models were developed and compared for the combined pyrolysis-gasification of two agro-industrial waste materials. The aim was to recycle greenhouse gas carbon dioxide for mitigating emissions, to evaluate the thermal behavior, reactivity, conversion and product composition in terms of structural/chemical characteristics of the fuels, and to provide accurate kinetic parameters useful in the scaling-up of the process. The experiments were conducted in a thermogravimetric system, coupled with a mass spectrometer. Both models accurately represented the pyrolysis process by three first-order reactions with deviation values ranging from 1.6% to 2.4%. For the gasification process, one pseudo-component described the process successfully, with deviation values of 2.3-5%. The IPR model provided a superior fit. Activation energy values estimated by the DAEM model were higher than those predicted by the IPR model.
Advancing Health Care With Digital Twins: Meta-Review of Applications and Implementation Challenges
Authors: Ringeval Mickaël , Etindele Sosso Faustin Armel , Cousineau Martin , Paré Guy
Published: January 2025

Background

Digital twins (DTs) are digital representations of real-world systems, enabling advanced simulations, predictive modeling, and real-time optimization in various fields, including health care. Despite growing interest, the integration of DTs in health care faces challenges such as fragmented applications, ethical concerns, and barriers to adoption.

Objective

This study systematically reviews the existing literature on DT applications in health care with three objectives: (1) to map primary applications, (2) to identify key challenges and limitations, and (3) to highlight gaps that can guide future research.

Methods

A meta-review was conducted in a systematic fashion, adhering to PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines, and included 25 literature reviews published between 2021 and 2024. The search encompassed 5 databases: PubMed, CINAHL, Web of Science, Embase, and PsycINFO. Thematic synthesis was used to categorize DT applications, stakeholders, and barriers to adoption.

Results

A total of 3 primary DT applications in health care were identified: personalized medicine, operational efficiency, and medical research. While current applications, such as predictive diagnostics, patient-specific treatment simulations, and hospital resource optimization, remain in their early stages of development, they highlight the significant potential of DTs. Challenges include data quality, ethical issues, and socioeconomic barriers. This review also identified gaps in scalability, interoperability, and clinical validation.

Conclusions

DTs hold transformative potential in health care, providing individualized care, operational optimization, and accelerated research. However, their adoption is hindered by technical, ethical, and financial barriers. Addressing these issues requires interdisciplinary collaboration, standardized protocols, and inclusive implementation strategies to ensure equitable access and meaningful impact.
Histopathological Comparison and Expression Analysis of COL1A1, COL3A1, and ELN in the Proximal and Distal Ventral Dartos of Patients With Hypospadias: Protocol for Prospective Case-Control Study
Authors: Raharja Putu Angga Risky , Birowo Ponco , Rachmadi Lisnawati , Wibowo Heri , Kekalih Aria , Duarsa Gede Wirya Kusuma , Abbas Tariq , Wahyudi Irfan
Published: January 2025

Background

The exact cause of penile curvature in hypospadias remains unknown. Resection of the dartos fascia has been observed to straighten the penis, indicating the involvement of the dartos fascia in the superficial chordee. However, the characteristics of dartos tissue in the distal territory of the ventral penile shaft may differ from those in the proximal aspect of the penile shaft.

Objective

This study aims to investigate the distinct histopathological profiles and expression of COL1A1 (collagen type 1), COL3A1 (collagen type 3), and ELN (elastin) in proximal and distal ventral dartos of patients with hypospadias compared to those without hypospadias.

Methods

This prospective case-control study compares the ventral dartos tissue of patients with hypospadias at different locations with that of patients without hypospadias. Dartos samples will be taken during surgery, with age matching. Histopathology examination uses hematoxylin and eosin and Masson’s trichrome stain. The mRNA expression of COL1A1, COL3A1, and ELN will be quantified using a 2-step reverse transcription–polymerase chain reaction analysis.

Results

Previous studies have documented different characteristics of dartos tissue between patients with hypospadias and those without hypospadias. Some studies even suggest resection of the dartos tissue during hypospadias repair. However, this is the first study to compare the characteristics of ventral dartos tissue in patients with hypospadias based on its location along the penile shaft, suggesting potential differences between the distal and proximal locations. We have obtained ethical approval to conduct a prospective case-control study aimed at elucidating these differences in dartos tissue characteristics. The findings of the study are anticipated to be available by 2025.

Conclusions

Differences in the characteristics of dartos fascia based on its location may require tailored surgical strategies. If the properties of distal dartos tissue closely mirror those of typical dartos tissue, the possibility of avoiding its excision during hypospadias surgery could be considered.

Authors: Kumssa Leta Bekere
Published: January 2025

The primary aim of this study is to establish the existence of a fixed point for FG(ξ, λ, θ)-generalized contractions in the context of bv(s)-metric spaces. The obtained result extends various well-established findings in metric spaces, b-metric spaces, rectangular b-metric spaces, and bv(s) metric spaces. Our discoveries not only expand upon and consolidate existing results in C-class functions but also build upon several previous contributions in the literature. Furthermore, we delve into and elaborate on the recently introduced concept of CG-class functions, providing illustrative examples.
DIFFUSED RELIGION OF VALUES
Authors: Cipriani Roberto
Published: January 2025

Modern diffused religion is not very different from that of the past. Indeed, it is precisely its persistence that gives it its peculiar characteristic. Diffused religion of values is the result of a vast process of religious socialization that continues to pervade cultural reality and not only that: it embraces central categories of religious behavior. It is reasonable to maintain that we are faced not only with a religion based on values largely shared, since they have been diffused chiefly through primary and, later, secondary socialization, but these very values can be seen in themselves as a kind of religion.

Authors: Diah Diah Ramadhani , Sumardi Dedy , Yuhermansyah Edi
Published: January 2025

Tanah Pusako Tinggi di dalam Adat Minangkabau merupakan bagian dari harta pusako tinggi yang diwarisi secara turun temurun dari Niniak kepada Mamak dan dari Mamak kepada Kamanakan. Pembagian tanah pusako tinggi dikenal dengan istilah Ganggam Bauntuak yang berarti diturunkan berdasarkan pertalian darah seketurunan ibu dan dikuasai dengan hak kolektif bersama dalam suatu kaum. Penguasaan dan pengelolaan tanah pusako tinggi beresiko menimbulkan sengketa yang terjadi di dalam ataupun diluar kaum. Berkaitan dengan ini, Kerapatan Adat Nagari berperan sebagai lembaga peradilan adat untuk menyelesaikan berbagai persengketaan yang diajukan oleh masyarakat nagari melalui jalan musyawarah untuk mencapai mufakat perdamaian. Penelitian ini mengkaji bagaimana mekanisme penyelesaian sengketa harato pusako tinggi oleh lembaga Kerapatan Adat Nagari Limau Purut dan bagaimana tinjauan Fiqh Siyasah Dusturiyah terhadap putusan dari Kerapatan Adat Nagari Limau Purut dalam menyelesaikan sengketa harato pusako tinggi. Metode penelitian yang digunakan adalah Yuridis Sosiologis dengan jenis Kualitatif. Berdasarkan hasil penelitian diambil kesimpulan bahwa penyebab terjadinya sengketa tanah pusako tinggi antara pihak A Cs sebagai penggugat dengan pihak BH Cs sebagai tergugat adalah karena adanya pengajuan permohonan untuk pengeluaran surat kepemilikan tanah atas nama BH Cs kepada KAN Limau Purut diatas tanah yang sudah dihibahkan oleh leluhur dari pihak penggugat A Cs. Pihak A Cs merasa hibah tersebut tidak sah karena tidak adanya pembuktian yang kuat menurut kesaksian kaumnya, sementara itu pihat tergugat A Cs melampirkan bukti surat tebus gadai dan hibah sebagai pembelaan diri. Mekanisme penyelesaian sengketa ini dilaksanakan sesuai dengan ketentuan adat bajanjang naiak batanggo turun dengan upaya putusan perdamaian berdasarkan adaik basandi syara’, syara’ basandi kitabullah yang mengacu pada konsep Islam fiqh siyasah dusturiyah dalam pengambilan putusan berpedoman dengan kaidah-kaidah Siyasah Dusturiyah yakni merundingkan, mengaktualisasikan, dan memberlakukan putusan.

Numerical Simulation of Premixed Turbulent Methane Combustion in a Multi-Inlet Cyclone Combustor
Authors: Yerzhan Assem , İlbaş Mustafa
Published: January 2025

The multi-inlet cyclone combustion chamber simulated in this study has 14 tangential gas/air inlets, each with an internal diameter of 9.525 mm, and is inclined 30° towards the front end of the combustion chamber in 2 symmetrical rows of seven. This study used CFD code to numerically simulate a multi-inlet cyclone combustor fueled by methane. The standard k-Ɛ model was chosen to simulate turbulent flow. Eddy Dissipation was used to simulate the combustion of a premixed mixture. The simulation was carried out for an air:fuel ratio (φ) of 1.0. The design velocity at the entrance to the combustion chamber is 20 m/s. In all cases, the inlet gas temperature was assumed to be T=300 K. The number of iterations was 3000.The other physical constans were taken from the literature. The computational default value was used for the operating pressure.

Precooling is a critical process in the post-harvest activities of vegetable and animal products. This research aimed to evaluate the relationship between animal products’ physical, mechanical, and chemical parameters and their relationship with the treatment combination of compressive force, cooling media, and type of animal product samples using a compressive type plate cooler. The research was carried out with three types of meat (beef, chicken, and fish), three compressive forces (0, 100, and 200 kg), and two types of cooling medium (ice cubes and dry ice). The results showed that PCA using XLSTAT could be used to reduce the number of parameters to two main components which could explain 75% of the total variation in the data set. PCA was able to group precooling treatments with cooling media based on the physical, chemical, and mechanical properties. Treatments using ice media for all types of meat and compressive forces were grouped in quadrants I and II, while those using dry ice media were grouped in quadrants III and IV. Based on the type of meat sample, the results of PCA were able to group beef and chicken samples in quadrants I and IV, while tuna fish samples were in quadrants II and III. Keywords: Animal product, Cooling medium, Force compression, P recooling, PCA.

Red palm oil (RPO) is known for its high carotenoid content, particularly β carotene and α-carotene, which provide significant provitamin A activity. However, it is susceptible to oxidation during frying and results in nutrient loss and quality degradation. This study investigates the effects of high temperatures and prolonged heating durations on the chemical and sensory properties of RPO. The experiment involved heating RPO at three different temperatures (140°C, 180°C, and 220°C) for durations ranging from 2 to 10 hours. Chemical analysis included peroxide values, free fatty acids, and changes in functional groups through Fourier Transform Infrared (FTIR) spectroscopy. Sensory evaluations focused on aroma and color alterations due to heating. Results showed that prolonged heating of RPO at high temperatures led to significant increase in peroxide values, and the formation of oxidation products, including aldehydes and ketones, which negatively impacted the sensory qualities. The oil darkened, and a burnt aroma developed, reducing overall sensory appeal. These findings provide new insights into the optimal frying conditions to preserve the nutritional and sensory qualities of RPO, particularly by minimizing heating duration and temperature. Keywords: Nutritional value, Prolonged heating, Red palm oil, Sensory attributes, Thermal oxidation.

Recently, melon cultivation in controlled environments such as greenhouse are popular to improve productivity and quality. However, environmentally friendly productions are necessary for preserving ecosystems and reducing environmental impact. This research aimed to evaluate the environmental impact using a life cycle assessment approach. Research was conducted using a life cycle assessment with six categories evaluated such as Global Warming Potential (GWP), Stratospheric Ozone Depletion (SOD), Terrestrial Acidification (TAC), Freshwater Eutrophication (FEU), Terrestrial Ecotoxicity (TEC), and Human Carcinogenic Toxicity (HCT) for kilograms of fresh melon. The result of GWP was 2.137 kg CO2 eq; SOD at 0.39(10-5) kg CFC-11 eq; TAC at 3.93(10-3) kg SO2 eq; FEU at 0.44(10-3) kg P eq; TEC at 4.62 kg 1.4-DCB eq; and HCT at 0.13 kg 1.4-DCB eq. Furthermore, the main contribution of environmental impact was cultivating media such as cocopeat and rice husk charcoal. The result of this research is important to improve greenhouse-based melon production. Keywords: Greenhouse, GWP, Life cycle assessment, Melon.

This research was conducted to explore the effectiveness of combined Trickling Filter (TF) and Rotating Biological Contactor (RBC) method in processing liquid waste from chicken slaughterhouses through local and economical media. Microorganisms were grown by inserting liquid waste into a TF tank containing gravel, used ceramics, coconut shells, and pumice. Subsequently, liquid waste flowed into a rotating biological contactor added with local microorganisms from stale rice and fermented banana stems. Waste treatment was carried out with variations in retention time of 1, 3, and 6 h. The results showed that at 6 h, the organic compound decreased significantly. The removal efficiency obtained was 87.05%, 82.11%, 90.51%, 22.57%, 79.36%, and 88.66% for Biological Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids, Total Dissolved Solids, Turbidity, and Ammonia, respectively. This high efficiency was supported by the collaboration between the activity of microorganisms attached to the TF biofilm and the use of local microorganisms in decomposing organic compounds in the rotating biological contactor. The combination of the two methods has been proven to help waste treatment process from chicken slaughterhouses in an environmentally friendly and efficient manner. Keywords: Biofilm, Chicken slaughterhouse waste, Local microorganisms, Rotating biological contactor, Trickling filter.
