Authors: Duggal Swati , Singh Ayaskanta , Garg Ram , M. Thorat M. , Varma Pooja
Published: February 2025

The paper is to investigate how well healthcare institutions function and if health and safety at work (OHS) initiatives correlate. Healthcare systems all over are under more and more pressure to raise performance, lower expenses, and enhance service quality. This makes it essential to investigate how programs for occupational health and safety may assist to raise the general effectiveness of healthcare operations. Given the very demanding nature of healthcare environments, OHS programs are supposed to safeguard the health and safety of healthcare professionals. Still, their influence beyond worker protection and is rather crucial in determining the degree of organisational performance. Many studies were conducted at many different healthcare institutions with rigorous OHS policies. The research examined topics like staff efficiency, patient satisfaction, cost-effectiveness, and absence rates using quantitative approaches. The research used statistical analysis to establish clear relationships between implementing OHS procedures and improving the practical outcomes in the healthcare sector. Particularly improved safety and health for employees have been connected to lower absenteeism, less accidents on the workplace, and increased staff contentment. Since a healthier workforce leads in improved patient outcomes, shorter wait times, and more effective treatment procedures, these developments directly affect healthcare services. The findings reveal that operating efficiency of healthcare institutions that give health and safety top priority is probably superior. The connection between the two emphasises the need of including health and safety guidelines into healthcare management strategies not just to meet the regulations but also to enhance the way things run. The research also emphasises the requirement of OHS programs in ongoing assessment and adaptation to meet evolving healthcare demands.

Published: February 2025

Bringing together healthcare management and environmental sustainability efforts has become an important way to deal with the world problems of health and environmental decline. Though they are distinct, both fields are closely related as they strive to improve society. More people desire services; costs are rising; environmental issues like pollution, climate change, and resource depletion are increasingly taxing healthcare systems all around. Concurrent with this, environmental sustainability initiatives seek to mitigate negative impacts of human activities on the planet by motivating individuals to use resources more sensibly and leave fewer residual carbon footprints. The links between environmental sustainability and healthcare management are examined in this essay together with the advantages and drawbacks of merging these two spheres. It discusses how medical institutions could reduce their impact on the surroundings by applying sustainable practices. They could advocate for medical products produced from sustainable materials and decrease waste and energy usage, for instance. The research also examines how public health is directly impacted by environmental problems such changes in ecosystems, restricted water sources, and bad air quality. The healthcare and environmental sectors must cooperate more closely if we are to build a long-term more resilient system. The article also covers how new tools, government regulations, and policy frameworks could assist to make healthcare practices more sustainable. It looks at the opportunities of green healthcare practices include hospitals using less energy, long-lasting healthcare supply lines, and making decisions considering environmental health. The coming together of these two areas is good for public health and helps with the larger goal of healthy growth around the world. Climate change and health problems are becoming more and more connected, so healthcare management systems need to start using environmental methods in their daily work. This all-around method can lead to a future where both people's and the planet's health are valued, making the world better and more sustainable for future generations.

Authors: Zhang Jianwei
Published: February 2025

The introduction of China’s digital yuan (e-CNY) marks a significant transformation in the country’s financial sector, impacting traditional banking, financial institutions, and consumer behavior. As a central bank digital currency (CBDC), e-CNY is designed to enhance financial inclusivity, increase monetary control, and reduce reliance on third-party payment providers. However, its widespread adoption presents challenges and opportunities for traditional banks, requiring them to rethink their business models, adapt to digital currency dominance, and develop new financial strategies to maintain competitiveness. This paper explores the regulatory framework, technological challenges, and financial sector implications of e-CNY, focusing on its effects on traditional banking business models, deposit structures, and loan issuance mechanisms. The study also examines consumer behavior, market adoption patterns, and the competitive landscape, highlighting the role of fintech firms and digital payment platforms. The discussion extends to financial inclusion, particularly in rural and underbanked regions, assessing the potential of e-CNY in bridging economic disparities. The research further investigates response strategies for commercial banks, including hybrid financial models, fintech collaborations, and AI-driven banking solutions. It also provides policy recommendations to ensure stability in the banking sector amidst digital transformation, including monetary policy adjustments, cross-border e-CNY integration, and cybersecurity measures. Findings suggest that while e-CNY presents short-term disruptions to commercial banks, it also offers long-term opportunities for financial innovation and international trade expansion. The paper concludes that traditional banks must embrace technological advancements, regulatory collaboration, and service innovation to maintain relevance in China’s evolving digital economy.

DIREITO DE MORRER
Authors: Cantini Adriana Hartemink , Bonorino Amanda Viegas
Published: February 2025

O tema morte é um grande tabu em diversas sociedades, a grande massa da população, e em especial os mais vulneráveis, não possuem privilégio de contratarem profissionais médicos e da área da enfermagem para que tenham um fim de vida em suas casas, acompanhado de familiares, sem sentir dor, o que transforma o tema do fim de vida num assunto não só de relevância ética e moral, mas também de relevância social. O prolongamento sacrificado da vida de pacientes incuráveis expõe o ser humano a situações humilhantes de dor e sofrimento. Portanto pesquisa-se sobre a Morte Digna, a fim de resolver a problemática de que quando não há mais uma vida digna e plena, e comprovadamente só é possível aguardar a morte, o paciente teria o direito de exercer sua autonomia encurtando o período de dor e antecipando a morte ou o Estado/Direito deve obrigar-lhe a manter a vida a qualquer custo? À vista disso objetivou-se conceituar os temas dignidade humana, autonomia da vontade, bem como explorar a Teoria da Ponderação, aplicando-se os princípios em confronto na questão da boa morte, quais sejam a vida versus a dignidade, para que pudéssemos decidir qual deve prevalecer e por fim, analisou-se como o tema é tratado na legislação brasileira. Para tanto realizamos uma pesquisa preponderantemente bibliográfica com a revisão de obras clássicas e levantamento de novas obras. Em suma, vislumbrou-se a possibilidade real da legalização da eutanásia no Brasil, permitindo concluir que o tema deve ser mais amplamente discutido tanto nas instituições políticas como na sociedade civil.

Assessment of Consensus Algorithms for Blockchain Technology to Enhance Decentralized Applications
Authors: Amen Saja
Published: February 2025

The accelerating pace of adoption of decentralized applications requires the use of efficient, high-performance blockchain infrastructures. These blockchains are supported by consensus algorithms that are critical determinants of scalability, transaction speed, costs, and security. Developers are still unaware of the most useful options because there is a large gap in information regarding the comprehensive evaluation of these algorithms in practice. This study aims to test and compare the performance of the three most popularly used blockchain consensus protocols - Proof of Work (PoW), Proof of Stake (PoS) and Delegated Proof of Stake (DPoS) with the aim to improve the application of decentralized systems. By deploying smart contracts on real blockchain test networks (Callisto for PoW, Sepolia for PoS, and Tron Nile for DPoS), the research explores key performance metrics such as block time, deploy gas fee, block gas limit, and block size. The experiments utilize tools like Remix IDE and Tron-IDE, highlighting the practical implications of consensus algorithms under varying real-world conditions, including network congestion and transaction volatility. Tron Nile excels in speed and capacity but incurs high gas fees, Sepolia balances performance with moderate costs, and Callisto emphasizes cost efficiency at the expense of speed and scalability. Insights derived from this study provide valuable guidelines for developers to choose suitable consensus mechanisms based on the specific requirements of decentralized applications

Published: February 2025

To reduce the accumulation of coal gangue and steel slag, a mixture of lime-steel slag-coal gangue for pavement base was prepared. Six groups of lime-steel slag-coal gangue mixtures were designed using a uniform design method. The 7 d unconfined compressive strength, 180 d compressive resilience modulus and 180 d splitting tensile strength tests, the freeze-thaw cycles, and the wet and dry cycles were carried out to study the mechanical properties, frost resistance and water stability. The expansion effect of f-CaO in steel slag on the mixtures was investigated by water immersion. SEM was used to explore microscopic changes in the mixtures. The field application of coal gangue mixture was carried out for two years. The results show that the regression equations obtained by the uniform test have high accuracy. With the increase of lime in the mixture, the mechanical strength, frost resistance, and water stability of the mixtures were first enhanced and then decreased. With the increase of steel slag, the unconfined compressive strength increased, the compressive resilience modulus increased at first and then decreased, the splitting tensile strength decreased, the BDR value decreased, and the strength loss of water stability increased gradually. The internal structure of the mixtures is stable and has good frost resistance. There is no obvious microscopical difference before and after freeze-thaw cycles. The immersion expansion rate of the mixtures was far less than 1.5 %.

Published: February 2025

Freshwater ecosystems (rivers and lakes) in Macedonia belong to two ecoregions. These are Eco region 420 (Southeastern Adriatic basin, Prespa and Ohrid lakes) and Eco region 422 (Vardar Basin with Dojran Lake). The Macedonian fish fauna consists of about 80 species of fish that live in Macedonian lakes and rivers. In large natural lakes (Prespa Lake, Ohrid Lake, and Dojran Lake), about 60 species of fish belonging to 15 families have been described, while other fish species are distributed in rivers and artificial lakes. Fish populations in Macedonia can be divided into autochthonous, nonnative, and invasive species. Twenty-two autochthonous and 7 introduced fish species were described in Lake Ohrid; 11 autochthonous and 12 introduced species were described in Prespa Lake; and 15 autochthonous and 7 introduced fish species were described in Dojran Lake. Other species that live in high mountain rivers are mostly autochthonous. Of the indigenous fish species, a large number of fish species in Macedonia are endemic and live in large natural lakes and rivers. The IUCN Red List is considered the most objective and authoritative system for classifying species in terms of extinction risk. According to the IUCN Red List, fish from Macedonian waters belong to the following categories: LC—35 species of fish, CR—3 species, EN—2 species, VU—9 species, NT—1 species, NE—1 species, DD—10 species, IN—18 species, and 1 species not categorized on the IUCN Red List.
The Ecology of the "Terroir"
Authors: Ducarme Frédéric ,   Center for Environmental Philosophy, The University of North Texas
Published: February 2025

Industrial agriculture led to a worldwide homogenization of crops and modes of cultures, but also of landscapes and relationships to the land, threatening at the same time biodiversity and cultural diversity. Developing alternatives to the agro-industrial system inherited from the twentieth century is therefore one of the greatest challenges facing humankind today. This article advocates for the promotion of the French concept of “terroir” as a foundational framework for preserving biocultural diversity, illustrating an ethical way of relating to the land. Already enshrined in European law for three decades and under study at the UNESCO and the FAO, it encourages farmers to adopt ecologically virtuous practices, while ensuring greater economic incomes. Moreover, it enhances the value of their work and their specific relationship with their environment in the long run. It also epitomizes broader worldwide initiatives, which propose basing agriculture not against the environment (both human and natural) but in symbiosis with it.

Published: February 2025

The concept of adab-based education according to Buya Hamka emphasizes the integration of knowledge, reason, and morals in forming individuals with noble character. Education is not only oriented towards the transfer of knowledge, but also towards the formation of character based on Islamic values. Hamka emphasized that reason as a gift from God must be utilized properly in seeking knowledge, while knowledge must be directed towards the right goals according to Islamic teachings. In addition, adab-based education includes respect for Allah, the Messenger of Allah, oneself, and fellow human beings as part of the formation of a complete personality. In social life, adab is the foundation for maintaining trust, building relationships, and obeying applicable rules. Therefore, this concept remains relevant in forming a generation that is not only intellectually superior, but also has strong morals and spirituality in facing the challenges of the times.
Anglo-Dutch Literary Relations in the First Quarter of the 16th Century: Jan van Doesborch’s Publishing Policy
Authors: Franssen Peter J A
Published: February 2025

This chapter discusses one of the earliest printers whose business model was predicated on publishing in multiple languages: Jan van Doesborch (d. 1536) was based in Antwerp for most of his life, but also spent a few years in London. His connections with English printers can be evidenced by the matter he printed, including translations from Dutch into English and ones from English into Dutch, and by woodcut illustrations recycled by English printers. Both types of evidence point to the transnationalism of Doesborch’s business operations: he was the Elsevier of the early 16th century.

Let \(\mu\) be a compactly supported positive finite Borel measure on  \(\mathbb{R}^d\).  Let \(0<\lambda_1\leq\lambda_2\leq\cdots\) be eigenvalues  of the Krein-Feller operator \(\Delta_{\mu}\).  We prove that, on a bounded domain, the nodal set of a continuous  \(\lambda_n\)-eigenfunction of a Krein-Feller operator divides the  domain into at least 2 and at most \(n+r_n-1\) subdomains, where \(r_n\)  is the multiplicity of \(\lambda_n\). This work generalizes the nodal set  theorem of the classical Laplace operator to Krein-Feller operators  on bounded domains. We also prove that on bounded domains on which the  classical Green function exists, the eigenfunctions of a Krein-Feller  operator are continuous.

Published: February 2025

La contratación pública es esencial para que los Estados adquieran bienes y servicios, fomentando el desarrollo local y la sostenibilidad. En Ecuador, el sistema prioriza la eficiencia, la transparencia y el apoyo a la Economía Popular y Solidaria. Sin embargo, en la parroquia Punín, cantón Riobamba, provincia de Chimborazo, las organizaciones de la Economía Popular y Solidaria enfrentan barreras significativas para participar en estos procesos, como son el desconocimiento, falta de recursos, infraestructura tecnológica y otros factores negativos. El estudio, basado en entrevistas con cinco organizaciones de la Economía Popular y Solidaria, revelan que la participación es mínima o inexistente debido a la falta de información y capacitación técnica, así como a requisitos administrativos complejos. Además, las políticas públicas favorecen a organizaciones más grandes y mejor preparadas. Pese a los desafíos, existen iniciativas aisladas, como capacitaciones del Ministerio de Agricultura y Ganadería en proyectos de fomento de la agricultura agroecológica, que representan pasos hacia la sostenibilidad. Sin embargo, estas medidas deben ser complementadas con políticas inclusivas que simplifiquen procesos y fomenten la participación activa de las organizaciones intervinientes en los procesos de contratación pública. Es crucial implementar estrategias que empoderen a las organizaciones de la Economía Popular y Solidaria, promoviendo su integración en el desarrollo económico y sostenible de sus comunidades. Solo a través de una mayor inclusión y colaboración entre autoridades y actores locales se podrá potenciar el impacto positivo de la contratación pública.

Published: February 2025

The drying process of hemp flowers is crucial for preserving the quality of cannabinoids, terpenes, aromas, and other valuable compounds. This study investigates the drying of hemp flowers using a condensation dryer, combined with a heat pump. This type of dryer allows for significant energy savings by retaining both the latent and sensible heat within the chamber. Although the drying process is somewhat slower than in conventional dryers, the quality of the drying is exceptional. The dryer operates at slightly lower temperatures, up to 60ºC, making it ideal for delicate products such as hemp flowers, herbs, and chopped fruits and vegetables. The drying process plays a key role in the retention of aroma and in the overall quality of the products. Key drying parameters, including air temperature, humidity, and the amount of condensate collected, are continuously monitored. Results will provide detailed hourly insights into these parameters, along with an analysis of the drying regime, offering recommendations for optimizing the process to preserve product quality.

Experimental investigation on the effect of water based nanofluids (Al₂O₃ and MgO) used as HTF in a PCM based thermal energy storage system integrated with constant heat source
Authors: Krishna Reddy , Meenakshi Reddy , Sreenivasa Reddy , Madhava Reddy , Venkata Mohan
Published: February 2025

This research focuses on evaluating the thermal performance of a combined sensible and latent heat storage unit using a packed bed design integrated with a constant heat source. The Thermal Energy Storage (TES) system features a cylindrical, insulated storage tank filled with spherical capsules containing phase change materials (PCMs) - specifically, paraffin wax and stearic acid. PCMs offer significant benefits in thermal management by enabling isothermal operation and higher thermal storage capacity, contributing to a reduction in system size and cost. To enhance the thermal conductivity of the heat transfer fluid (HTF), nanoparticles are introduced into water, creating nanofluids that improve the efficiency of heat transfer. These water-based nanofluids facilitate heat transfer between the constant heat source and the storage tank, serving as a sensible heat storage medium. The study examines different HTF configurations, starting with water alone and extending to nanofluids with Al₂O₃ and MgO nanoparticles at three volume concentrations (0.2%, 0.5%, and 0.8%). Experiments were conducted at varied flow rates of 2, 4, and 6 liters per minute to analyze the effect of these parameters on heat transfer and PCM melting time. Performance parameters, including charging time, instantaneous stored heat, cumulative stored heat, and system efficiency, were evaluated for each HTF-PCM combination. Additionally, batch-wise discharging experiments were conducted to assess the system's heat recovery capability. The results offer insight into the comparative advantages of different HTF materials and configurations, highlighting the thermal performance enhancements achieved by using nanoparticle-enhanced HTFs.

Published: February 2025

LANDFILL gas (LFG), which mainly includes methane, is a greenhouse gas collected by extraction systems, released into the air, or directly used to generate electricity. The paper measured the temperature of landfill gas (LFG) on biothorns, at the landfill in Nish, and investigated the possibility of utilizing the potential of landfill gas before its closure. Infrared thermographic method (IF) of radiation was used to test the QUANTITY of methane on the passive system. The paper concludes that heat and gases are released that cannot be further used for the production of electricity in thermal power plants. Analyzing the results, no thermal irregularities in the immediate environment were observed, and the conclusion is reached that the passive GASA degassing system has no impact on the environment.

Published: February 2025

Decarbonization of all segments of energy systems, both on the supply and demand side, is one of the main goals of the energy transition. Electricity supply in the future will largely rely on generation from intermittent energy sources: wind and solar. Locally available, non-utilized alternative low-temperature energy sources as hydro-geothermal wells, and abounded oil and gas wells, have the potential to provide continual energy production over the year. Electricity generation from these energy sources is carried out with working fluids with low evaporation temperatures. Commonly used fluids are categorized into several groups based on their chemical composition, which determines their thermophysical properties. In this paper the effect of chemical composition of six fluids from three groups on thermophysical properties was analyzed. The effect of fluids' properties on the efficiency of ORC is analyzed for the case of a typical range of temperatures of hydro-geothermal and abounded oil and gas wells in Serbia, which may be used as heat sources for electricity generation.

Published: February 2025

Heat pumps are among the crucial technologies for increasing renewable energy utilization in the building sector. One of the main factors for adopting heat pumps is their economic attractiveness, which depends on several factors. Air-source heat pumps are especially challenging in this regard because their performance relates significantly to the outdoor conditions. Optimization of operational regimes can lead to lower running costs of heating systems with heat pumps. However, most research efforts in this area are based on relatively simple pricing rules. This paper presents an attempt to perform operation optimization of a heating systems based on a realistic electricity pricing policy, applicable to the households in Serbia. The approach uses the results of detailed building simulations and existing rules for charging electricity as the inputs. It applies mixed integer linear programming to obtain the operation regimes that minimize the operational cost of a heating system over one year. The paper shows the comparison of the obtained results and the results drawn from simplified electricity pricing rules. Finally, it discusses the importance, applicability, and limitations of the presented approach.

Authors: Onysko Oleh , Kopei Volodymyr , Panchuk Vitalii , Ivaniv Ivan , Verkalets Anatolii
Published: February 2025

The accuracy of closing and opening of gate valves or taps, and accordingly the efficiency of energy saving, largely depends on the accuracy of the lead screw. Lead screws are mostly made using lathes. The accuracy of the thread of the lead screw is primarily the accuracy of the thread profile. Basically, the shape and profile of the screw must meet the standards of the trapezoidal thread and, accordingly, with the Archimedean form. However, based on the real conditions of the turning process, the shape of the thread will have a convoluted character, which functionally depends on the accuracy of the setting of the needle relative to the part. Taking this approach into account, it is possible to effectively apply the calculation algorithm, which provides for the maximum possible accuracy of the actual production of a lead screw with a trapezoidal or triangular profile.

Published: February 2025

The present work is a theoretical investigation of the organic Rankine cycle (ORC). A simplified cycle is studied aiming to determine the ORC thermodynamic efficiency in an analytical and simplistic way. Reasonable assumptions have been made and the methodology is based on an analysis of the cycle depiction in the temperature - specific entropy diagram. An analytical solution for the ORC efficiency was developed using the low cycle temperature, the high cycle temperature, the superheating degree, the liquid and vapor-specific heat capacities and the fluid latent heat at the high-temperature level. The reported mean deviation of the suggested analytical model compared to the detailed thermodynamic one was found at 5.03% which is an acceptable value. Moreover, analytical approximations for the efficiency with regression models were created for three different working fluids names n-pentane, toluene and R600. The present approach can be extended to extra working fluids and operating conditions and the present work consists of the first step for the establishment of this methodology.

Refining resource management in healthcare delivery processes: Should we look at technology changes another way?
Authors: Vilmányi Márton , Mátó Ágnes , Tarjányi Margit , Kálmán Melitta
Published: February 2025

Background: Today's health organizations are under increasing pressure to meet a range of sometimes conflicting, often divisive goals. Consequently, they need to maximize the value created for patients as an overarching goal. Value can be addressed through organizational processes managed through activities, actors and resources. Managers perceive this interaction process mainly through resource and cost dimensions. However, the extent of the change in resources, i.e. the change in value creation caused by a new technology, has not yet been investigated. Purpose: In our study, we examine the consequences of technological alterations resulting in a change regarding resources that impact value creation. We seek to describe the change patterns in resource compositions that occur when introducing a new technology into an organizational process. Study design/methodology/approach: We adopted a case study method with a process perspective, where we applied the Time-Driven Activity-based Costing (TDABC) framework to capture the managerial perspective on cost and resource management related to value creation. Five healthcare protocols implemented using different technologies (face-to-face and telemedicine) were analyzed. Findings/conclusions: Resource changes due to technological modifications seemingly occurred without a distinct pattern. However, we could confirm that the changes not only affected activities in areas where new resources were introduced, but also had spillover effects. Our results reveal that the extent of changes caused by technological alterations can be determined through changes detected in information. The results highlight the importance of the extent of change and information management. Limitations/future research: The most significant limitation to generalizing our findings is the research context itself. The sector-specific characteristics of the healthcare sector limit the generalizability of our results. Another limitation is the number of observed cases and our research method. This suggests the need for further research, as it seems justified to test the TDABC methodology on multiple other cases.

Kapasitas pengendalian listrik atau kualitas kapasitas pengendalian dalam sistem kelistrikan senantiasa sangat vital. Namun, perhatian utama harus difokuskan pada karakteristik tegangan pasokan, terutama di era modern. Kendala utama dalam struktur kelistrikan adalah tegangan yang rendah. Tegangan rendah menjadi sumber gangguan dalam sistem kelistrikan yang berdampak pada kelincahan peralatan listrik terkait dan dapat mempersingkat umur peralatan, termasuk komponen baterai pada sistem energi DC seperti panel surya. Untuk mengantisipasi situasi tersebut, digunakan perangkat keras pemutus arus tegangan rendah guna melindungi baterai dan perangkat DC dari kondisi tegangan rendah, menggunakan potensiometer sebagai pengatur tegangan, IC 7809 sebagai penurun tegangan input baterai, saklar untuk memutus hubungan baterai, sumber daya listrik, serta penunjukan tegangan pada layar LCD dan kontrol mikrokontroler menggunakan Arduino Nano. Strategi yang diterapkan dapat berupa strategi pertumbuhan atau strategi penelitian dan pengembangan. Pendekatan ini merupakan landasan untuk merencanakan dan membangun pemutus arus tegangan Moo guna melindungi baterai dan perangkat DC. Dalam uji coba tegangan, Moo mampu melepas baterai DC dengan ketepatan ±99,795%. Uji standar untuk pemutus arus tegangan rendah pada 12 V dan 24 V menunjukkan perbedaan sebesar ± 0,096 V dan kesalahan ± 0,554%.

Differences in Viewer Responses of Men and Women to the Story of the Film Kite Drops. This study aims to describe the responses and factors that cause differences in the responses of male and female viewers to the story of the film Layangan Putus. Data collection was carried out using literature study techniques and questionnaires using the response perspective theory of Hans Robert Jauss. The results of the study show that: (1) the responses of men, especially those who already have a partner or wife, describe more of their complaints because their partners or wives become more suspicious; (2) the responses of female viewers, especially those who are not yet married, describe more caution because they are careful in choosing a partner; and (3) the cause of differences in the responses of male and female viewers is that the horizons of expectations that each man and woman have are different, making it possible for the difference in acceptance of the film Layang Disconnect.
