Authors: Ojukwu Henry Sonna
Published: September 2024

Irrespective of country and economy, organizations around the globe are constantly scanning for ways to enhance their competitive position for sustained industry performance amidst heightened competition. Rather than competing against each other, these firms view themselves as strategic partners for long-term industry relationships. To this end, the study analyzed how theoretical Synthesization would greatly influence the positional standing of aligning firms. To achieve the study intent, the scoping review approach was employed. Study materials were mainly journal articles sourced from academic search engines and institutional databases. The study clearly states that regarding strategic alliance and competitive advantage, the essence of possessing rare, uncopiable, and non-substitutability organizational resources should be for inter-organizational purposes rather than individualist exploitation.
SUPPLY CHAIN DISRUPTION AND SUSTAINABILITY OF PHARMACEUTICAL FIRMS IN ANAMBRA STATE, NIGERIA
Authors: Eze Solomon Uchehukwu
Published: September 2024

The pharmaceutical sector, in Nigeria plays a role in the nations’ healthcare system by supplying medications to the people. However pharmaceutical companies in the Anambra State have been facing obstacles recently due to disruptions in their supply chains. This research investigates how supply chain disruptions impact the sustainability of firms in Anambra State. A mixed-methods approach, involving qualitative interviews with industry experts and quantitative analysis of operational data, identifies the main causes of supply chain disruptions and their effects on this firm’s long-term success. The research reveals that supply chain disruptions result from factors such as delays in customs clearance, inconsistent regulatory policies, currency fluctuations, inadequate transportation infrastructure and issues with supplier reliability. Interviews with industry experts highlighted customs delays as a disruption while quantitative analysis showed a 20% increase in times for imported pharmaceuticals along with a 15% rise in delivery delays and a 10% increase in product returns due to transportation challenges. Moreover, inefficiencies in inventory management were observed, leading to a 5% rise in holding costs and a 3% decrease in turnover rates due to supply chains. Challenges related to suppliers involved issues, with delivery reliability and product quality leading to a 10% extension in supplier lead times and a 5% uptick, in returns. The findings highlighted a direct correlation between these supply chain issues and decreased profitability, operational efficiency, and the ability to meet patient needs, emphasizing the urgent need for improvements to enhance the resilience of the pharmaceutical supply chain in Anambra State.
Motivation for "tattoo" or what justifies the costs of self-expression of an individual
Authors: Medvedeva Elena , Kroshilin Sergey
Published: September 2024

The purpose of the article is to identify new trends in the perception of tattoos in modern society with an additional focus on analyzing the motives for making decisions about their application, including the financial aspect of the costs of this type of self-expression of an individual. The object of the study - dominant reasons/factors of tattooing in modern realities. Subject - modern trends in the perception of tattoos by different categories of working Russians with a focus on identifying contradictions between self-actualization through tattooing and emerging obstacles from society. The authors use analytical approaches and statistical methods of comparison in analyzing secondary and obtaining primary data on the studied problems. Data from the authors' 2023 surveys were used as primary data. The method of content analysis of statements during the thematic discussion on the portal of pedagogical community was also used. As the research has shown, the situation within society is ambiguous. A significant number of Russians are interested in self-expression through tattooing, but society still has a traditionally wary attitude towards tattoo wearers, especially those employed in social sectors. For tattoo wearers, regardless of their professional credentials, there are often significant barriers to employment and career advancement. Despite this, the study shows a growing trend in the number of tattoo wearers. Those who have already got them earlier are ready for further financial expenditures for renewal of old and application of new tattoos. The amount of money that respondents plan, want and can spend on tattooing, despite the difficult economic situation, reaches 100 thousand rubles. The results of the study can be practically significant for scientists, specialists, as well as researchers of consumer behavior of Russians from the point of view of economic aspects of decision-making on new types of goods and services and the formation of spending on self-expression.
Problems and prospects for employment of young Russian teachers
Authors: Bulanova Marina
Published: September 2024

The article raises the problems related to the peculiarities of building a professional career of graduates with pedagogical education. Despite the constant demand in the labor market, educational organizations are in a situation of chronic shortage of teaching staff. The aim of the article is to analyze the difficulties and challenges faced by young teachers not only during employment, but also during the period of adaptation in an educational institution. Based on a large array of statistical data, as well as sociological studies conducted by the research teams of Institute of Sociology of FCTAS RAS and RSUH, risk factors and channels of leaving the labor market of young teachers-professionals shown. The article poses, firstly, the problem of insufficiently meaningful choice and, as a consequence, motivation of future teachers during their enrollment in the university, the formation of “professional ballast” of students unmotivated for the profession of teacher. Secondly, the problem of lack of necessary vacancies, insufficient salary, uncomfortable working conditions. Thirdly, the problem of adaptation to work in an educational institution: the lack of stress resistance, professionalism, communication competence, responsibility and initiative. It is concluded that in order to attract young teachers to schools it is necessary to take thoughtful measures to retain motivated people in the profession, starting from the university stage and ending with the creation of favorable conditions for their career development in the workplace.
Features of political participation of Russian youth in the context of digitalization
Authors: Anishchenko Alexander
Published: September 2024

The article is devoted to identifying the specifics of the influence of the "digital" factor on the dynamics and transformation of political activity of modern Russian youth. The author pays special attention to the role of social networks and digital media on the political participation of the younger generation. Today, not only is the trend towards the emergence of diverse strategies for online political activity of Russian youth increasing, but significant changes are taking place in the differences in role models of political participation that differentiate passively engaged "viewers" and active activists. Those young Russians who actively use online resources in their socio-political activities are already quite effectively using digital technologies and ways to attract a new audience, social mobilization, finding supporters, coordinating joint actions, etc. It is noted that the key trend in recent years has been the "digitalization of political participation" of young people and the spread of the phenomenon of online political participation. The author concludes that despite the steady growth in the number of young users of social networks and consumers of digital media, the increasing role of these online resources as political factors should not be exaggerated in the process of political mobilization. The transformation of the socio-political context and the decrease in the general level of protest moods in society, the "calming down" of spontaneous mobilization in the "offline" certainly leads to a decrease in the mobilization value of social networks, and to a reduction in the number of protest-minded youth.
Towards a scientific interpretation of the social effectiveness of education
Authors: Osipov Alexander
Published: September 2024

The article substantiates the problem of the social effectiveness of education as the main scientific and practical product and, at the same time, as the area of theoretical integration of the sociology of education. Its solution is a prerequisite for overcoming bureau-pathologies and the transition from universal and bureaucratic management to scientific management of education. The approach to the social effectiveness of education is disclosed on the basis of the concept of its institutional functions, as the ratio of socially significant results to the total costs (including intangible) of education. The interpretation of this problem involves: determining the methodological role of sociology in solving this theoretical and applied problem; taking into account the entire spectrum of institutional functions (impact on all spheres of society, delay in results in time; irreducibility to a market service or pedo-centric and "competence" schemes); interdisciplinary interaction for the conceptualisation of social costs and results.
The absence of the concept of "social effectiveness of education" in the current legislation of the Russian Federation creates a normative space for bureaupathologies in educational policy. Bureaucrats replace the public efficiency of education – a multi-component criterion of management quality – with project management that is advantageous to them. They ignore the extensive responsibility of education in society, breaking up its management into short projects, and in this the bureaucrats´ actions merge with neoliberal “modernisations” and pedo-centric “reforms”, leading education to a crisis, waste of state resources, and lagging behind in global competition.
The author comes to the conclusion that in order to solve the problem of efficiency, a methodology for analysing public costs and results of education within the framework of its institutional functions is necessary. Successful development of the concept of public efficiency will ensure the accelerated development of the sociology of education in Russia against the background of global trends of shallow topics and theoretical disintegration of this branch of science. The latter, in the author's opinion, fully meets the priorities of Russian society, education and science.

Authors: Badak Bartu , Sendil Ahmet Murat , Yılmaz Arda Şakir , Salış Mustafa
Published: September 2024

Granulomatous mastitis is a rare benign inflammatory disease of the breast. Although the etiology of granulomatous mastitis is not known exactly, it can be confused with breast cancer due to its findings and appearance. In addition, this disease, which is characterised by inflammation, causes recurrent infections and considerable tissue loss if left untreated. Therefore, diagnosis and early treatment are very important. In our study, we aimed to show the results of intraoperative local steroid administration after surgical resection in the treatment of patients with granulomatous mastitis. In our study, the hospital records and files of 39 patients diagnosed with granulomatous mastitis and treated with surgical treatment and intraoperative local steroid administration were retrospectively analysed. Age, gender, radiological and laboratory findings, surgical methods, postoperative recurrence rates and histopathological features were noted. Success rates were investigated and it was observed that intrathecal steroid treatment given after resection decreased recurrence. As a result, it was concluded that surgical wide or total excision and intraoperative local steroid administration would be the most appropriate treatment for the definitive treatment of granulomatous mastitis. Although abscess drainage and antibiotic treatment is effective in rare cases, surgical treatment should be preferred in chronic and complicated cases.

Application of ferromagnetic materials for technological processes thermal regime stabilization (Review)
Authors: Mikulionok Ihor , Ivanenko Olena
Published: September 2024

The research focuses on the technological and auxiliary equipment used in various industries that require maintaining a specific narrow temperature range.
The study aims to critically analyze the potential use of structural elements made of ferromagnetic materials with a second-kind phase transition temperature (Curie temperature or Curie point) in high-performance, knowledge-intensive industries, particularly the chemical industry. These materials correspond to the required temperature of the processed or transported liquid or loose medium.
The technological processes using the magnetothermal effect and the corresponding designs of equipment are considered: heat exchange, heat and mass exchange, mechanical and hydromechanical, equipment for processing thermoplastics, as well as other devices used in various branches of industry, in particular chemical, food and microbiological, in thermal energy, metallurgy, agriculture, medicine and construction. It is shown that the specified method of ensuring the required thermal regime is suitable for use primarily in large-tonnage continuous production.
As the conducted studies have shown, the proposed approach to stabilizing the heat flow of various technological and auxiliary equipment is effective and quite promising. The indisputable advantage of the corresponding method is to ensure a certain temperature of the working parts of the equipment with high accuracy, however, this method is quite difficult to implement on the existing equipment, which is mostly made of magnetic materials (steel, cast iron). Therefore, to implement the proposed method in practice, it is necessary to develop new equipment designs or to subject existing samples to deep modernization. At the same time, there may be difficulties associated with the search for existing or the creation of new ferromagnetic materials with the required thermomagnetic properties for the manufacture of appropriate structural elements of technological and auxiliary equipment. However, in certain cases, the proposed method of maintaining the specified temperature of the processed media may become the most appropriate (primarily in fine chemical technology, biotechnology, pharmaceuticals, precision instrument manufacturing, microelectronics, and medicine).

Authors:   Department of Chemistry, Faculty of Mathematics and Natural Sciences, IPB University, Virgilius Raja David , Batubara Irmanida
Published: September 2024

The ethyl acetate extract of fungus comb was investigated for its potential as an α-glucosidase enzyme inhibition agent. The extract was evaluated using bioassay methods to determine its IC50 values against enzyme activity, alongside phytochemical screening to identify active compounds. The optimal concentration of α-glucosidase enzyme was determined to be 0.06 U/mL. Results indicated that the extract and its fractions exhibited α-glucosidase enzyme inhibition activity, albeit with IC50 values higher than the positive control, acarbose. Fractions containing phenol-hydroquinone showed the most vigorous activity, while fractions containing saponins displayed varied activities, possibly due to contaminants interfering with enzyme interactions. This study highlights the potential of the fungus comb extract as a promising source for developing antidiabetic agents.
Ecological shifts in lagoon patch reefs: consequences of large-scale alterations to coastal systems
Authors: Sullivan Sealey Kathleen , Lennon Ellery , Roskar Amelia Grace , Patus Jacob
Published: September 2024

Anthropogenic and climate alterations of coastal environments impact enclosed tropical marine lagoons more directly than offshore marine systems. Long-term studies of lagoonal patch reefs in the central Bahamas were reviewed using a threat assessment matrix to understand spatial and temporal changes in patch reef diversity. A 13-year dataset that includes both epifaunal invertebrate and fish surveys was used to address two research questions: (1) Are there spatial patterns of diversity loss across the tropical lagoon linked to distance from potential land-based sources of pollution? (2) Are there temporal patterns of diversity loss in the tropical lagoon linked to specific storm events or anthropogenic changes over time? The answers to both questions were “yes”; there were spatial and temporal patterns in patch reef diversity, but these patterns were not as expected based on the threat assessment. Patch reefs across a spatial scale contribute individually to the biological diversity and function of the tropical lagoon. Temporal changes were more significant than spatial differences across the lagoon. Fish assemblages showed a significant loss of both species and trophic diversity over time. Changes in the benthic epifauna assemblages supported more weedy, short-lived species, contributing to reduced rugosity, which may have exacerbated declines in fish diversity. Results indicate a need for greater protective measures for the entire Elizabeth Harbour.
Nexuses of critical minerals recovery from e-waste
Authors: Mohamed Abdel Mohsen O.
Published: September 2024

Critical minerals (CMs) are essential for the development and function of renewable energy technologies, such as solar panels, wind turbines, and batteries, and for utilization in other industrial sectors, such as high-tech., automotive, information technology, aerospace, and defense. Recycling these minerals from electronic waste (e-waste) offers a sustainable solution to meet the growing industrial demand, if done technically effectively and with appropriate process inputs and rewards. This study proposes a holistic approach in addressing CMs recovery from e-waste. In doing so, seven connecting factors (nexuses) were identified and discussed. These nexuses are as follows: (i) the technical dimension that addresses the limitations of the current technologies used for e-waste recycling and recovering; (ii) the energy dimension addressing the level of consumed energy in the recycling and recovery processes; (iii) the economic dimension that addresses the economy of scale; (iv) the consumer dimension in view of consumer and manufacturer attitudes toward recycling; (v) the circularity dimension that deals with the circular design principles aiming to promote the recyclability and sustainability; (vi) the technical innovation dimension, particularly through the integration of digital technologies; and (vii) the research and development effort dimension aiming at advancing recycling technologies and recovery processes. Overcoming these limitations is crucial for maximizing resource recovery rates, reducing environmental impacts, and promoting the transition toward a more sustainable and circular economy.

Published: September 2024

This research seeks to provide local governments with a comprehensive alternative for the proper maintenance of roads, focusing on the surface and functional evaluation of pavements. It com-pares conventional methods of the International Roughness Index (IRI) and the Pavement Condi-tion Index (PCI) with novel methodologies that employ smart technologies. Road maintenance is essential for economic development, facilitating the circulation of services and resources. This re-search analyzes the efficiency of smart technologies in the maintenance of local roads in Arequipa, taking as a case study a 2 km section of the AR-780 highway in Polobaya. The International Roughness Indices (IRI) obtained through the Merlin Roughness Meter and the Roadroid applica-tion were compared, finding a minimum variation of 4.007% in the left lane and 8.5% in the right lane. Roadroid turned out to be 60 times faster than the conventional method, with a cost differ-ence of 220.11 soles. Both methods classified the road condition (PSI) as GOOD, validating the accuracy of Roadroid. In addition, the Pavement Condition Index (PCI) was evaluated with con-ventional methods and a DJI Mavic 2 Pro drone, finding a variation of 6.89%. The cost difference between the methodologies was 1,047.73 soles, and the use of the drone proved to be 10 times faster than visual inspection. Finally, it can be said that this study contributes to closing the knowledge gap regarding the use of smart technologies for better pavement management on local roads, so that the actors in charge of the roads can make decisions based on science and thus con-tribute to the well-being of the population.
Is Animal Magnetoreception Quantum? A Perspective from the Energy Resolution Limit
Authors: Kominis Iannis , Gkoudinakis Efthimis
Published: September 2024

A large number of magnetic sensors, like superconducting quantum interference devices, optical pumping and nitrogen vacancy magnetometers, were shown to satisfy the energy resolution limit. This limit states that the magnetic sensitivity of the sensor, when translated into a product of energy with time, is bounded below by Planck’s constant, ħ. This bound implies a fundamental limitation as to what can be achieved in magnetic sensing. Here we explore biological magnetometers, in particular three magnetoreception mechanisms thought to underly animals’ geomagnetic field sensing: the radical-pair, the magnetite and the MagR mechanism. We address the question of how close these mechanisms approach the energy resolution limit. At the quantitative level, the utility of the energy resolution limit is that it informs the workings of magnetic sensing in model-independent ways, and thus can provide subtle consistency checks for theoretical models and estimated or measured parameter values, particularly needed in complex biological systems. At the qualitative level, the closer the energy resolution is to ħ, the more “quantum” is the sensor. This offers an alternative route towards understanding the quantum biology of magnetoreception. It also quantifies the room for improvement, illuminating what Nature has achieved, and stimulating the engineering of biomimetic sensors exceeding Nature’s magnetic sensing performance.
Artificial Intelligence in Flight Safety: Fatigue Monitoring and Risk Mitigation Technologies

Published: September 2024

With the improvement of computer, artificial intelligence, information technology and other technical levels, the relationship between man-machine environment systems is more complicated and diversified. The optimization, iteration and development of the new generation of intelligent equipment system and human-computer interaction interface put forward higher requirements for ensuring the safety of personnel, improving the efficiency of human-computer interaction and improving the efficiency of the system. Such as intelligent cabin adaptive cognitive decision aid system, how to adopt intelligent information display and human-computer interaction, optimize information processing, strengthen situational awareness; How to effectively present information and improve the efficiency of human-computer interaction, so that the system has good security, applicability and maximize its effectiveness; How to deal with man-machine matching and man-machine collaboration problems, so as to improve the efficiency of man-machine/unmanned collaborative work. Human factors throughout the life cycle of equipment systems must be fully considered. The human factor is considered in the system design, so that people, machines and the environment can work together and adapt to each other, so as to achieve benign interaction and feedback between people and equipment and interface and complete the full transmission and communication of human-machine intelligent interaction information. The development of new aircraft human-computer interaction systems combined with new technological methods has also gradually changed the role of pilots and staff. From the system operator gradually into the monitor and decision maker, especially with the improvement of the degree of intelligent flight, information technology, advanced complex airborne equipment is increasing, the amount of information that operators need to deal with is also increasing, and the allowed time for judgment and decision is very short, and the mental resources that pilots bear are gradually rising. As the mental load is a key factor affecting the allocation of cognitive tasks, when encountering emergency situations, the mental load overload caused by the increase of information processing tasks often occurs, which seriously affects the task performance of operators, physical and psychological comfort and flight safety, and thus affects the efficiency and safety of the entire aircraft man-machine system. This requires us to conduct real-time analysis of human-computer interaction situational awareness, especially the individual cognitive state as an uncontrollable factor.
Optimizing Exotic Option Pricing: Monte Carlo Simulation and Variance Reduction Techniques
Authors: Gottimukkala Srinivas Raju
Published: September 2024

This study investigates the pricing of exotic options, specifically Barrier and Asian options, through the application of Monte Carlo simulation. The research commences by establishing the theoretical foundations and closed-form solutions within the Black-Scholes framework. Subsequently, three distinct random walk models are introduced to generate underlying asset paths for simulation purposes. The antithetic variate technique is demonstrated to significantly reduce standard error and accelerate convergence in the pricing of both options, thereby enhancing the precision of Monte Carlo estimates. Notably, the selection of underlying random walk models is found to have a minimal impact on accuracy, suggesting avenues for further research in advanced variance reduction techniques. This study provides valuable insights into the pricing of exotic options, offering implications for finance professionals and researchers, and driving innovation in option pricing methodologies for dynamic financial markets. The research underscores the efficacy of Monte Carlo simulation and variance reduction techniques in pricing complex options, contributing to the advancement of financial modelling and derivatives pricing.
Rethinking Climate Justice: Insights from Environmental Sociology
Authors: Islam Md Saidul
Published: September 2024

This paper reexamines climate justice through the framework of environmental sociology, offering fresh perspectives on the intersection of social and ecological systems in the face of escalating global climate crises. It emphasizes that inequality lies at the heart of global climate politics, often obstructing pathways toward achieving true climate justice. Drawing from established traditions within environmental sociology—such as the new ecological paradigm, the post-growth society, and the environmental justice paradigm—the paper advocates for profound systemic and structural reforms in political and economic systems to tackle entrenched inequalities. By integrating these frameworks, the paper proposes a comprehensive model of climate justice, encompassing material, procedural, compensatory, and transformative justice. This holistic approach not only addresses environmental sustainability but also prioritizes social equity, ensuring that marginalized communities are included in the global response to climate change. The paper thus positions climate justice as a critical component of broader environmental and social transformation.
Reproduction of the dog snapper Lutjanus jocu in captivity, linking ecological, and production observations
Authors: Malanski Evandro , Malanski Ana Cecilia Gomes Silva , Fernandes Luiz Fernando Loureiro
Published: September 2024

Snappers’ domestication for reproductive purposes is a first step to allow future offering of high quality, more sustainable fish products, generating ecological advantages to the marine ecosystem such as the reduction on the pressure of current stocks. The dog snapper Lutjanus jocu is a very important species with very little information on its capability for domestication. For that reason, dog snappers were collected in the coastal area and maintained in laboratory to verify their capacity to be domesticated and achieve reproductive success. A specific protocol was designed for their maintenance in recirculating aquaculture systems and is presented in the methods section. The domestication of wild specimens until they achieved reproductive success and produced viable eggs in captivity took approximately 2.5 years. Spawning events produced an average of about 25,000 eggs, or about 2,100 eggs·kg-1 of broodstock, with an average of three events per week. During new and full moon, the viability of eggs was higher, showing a strong influence of the lunar cycle in their reproduction. Spawning activities only happened during the night, and embryo development took about 535 degree-hours. Our results concluded that the dog snapper L. jocu can be conditioned in captivity for reproductive purposes, with consistent production of eggs in a weekly basis, enabling the possibility of a large-scale production to help reduce the pressure on the natural stocks.

Authors: Subedi Narayan Prasad , Yorozuya Atsuhiro , Egashira Shinji
Published: September 2024

The present study discusses flood hazard characteristics in the lower reaches of the West Rapti River based on the results obtained from field surveys and numerical computations using depth averaged 2-D numerical models for flood flow and associated sediment transportation. To evaluate the inundation process with sediment erosion and deposition in the floodplain, a new erosion term was introduced into the mass conservation equations for suspended sediment and bed sediment. The results obtained from numerical computations indicated that field data on the spatial distributions of depths for inundation, and sediment erosion and deposition can be evaluated by the numerical model. Thus, numerical predictions were performed for the inundated areas, and the accumulated volumes of sediment erosion/deposition for floods with return periods of 50, 100, and 200 years, as a step towards damage assessment and risk assessment due to floods with active sediment transportation in the floodplains.

» For the common median and ulnar entrapment neuropathies, published normative values for nerve cross-sectional area at the wrist and elbow have demonstrated a high degree of diagnostic validity of diagnostic ultrasound.

» Expert consensus on best practice for the clinical use of these reference is lacking and should be a logical next step in the deployment of ultrasound for upper extremity neuropathy evaluation.
A review of habitat modeling methods that can advance our ability to estimate the ecological cobenefits of dredge material placement

Published: September 2024

Beneficial use of dredged material (BUDM) has been a placement strategy within the US Army Corps of Engineers (USACE) for over 35 years, with applications that aim to reduce navigation costs, increase flood protection, and generate ecological benefits. However, the tools and approaches used for estimating ecological benefits are often limited in comparison with those available to evaluate costs and more traditional economic benefits when moving and placing dredged material. There are statistical and mechanistic models that can aid in quantifying habitat benefits within the context of BUDM projects, but there is currently no USACE-approved process that facilitates the integration of these modeling approaches. The purpose of this document is to provide a comprehensive review of existing habitat-centric statistical and mechanistic models that may aide USACE in identifying models most appropriate for quantifying potential ecological benefits and trade-offs at placement sites.

This study aims to compare the consumption theories of John Maynard Keynes, a conventional economist, and Monzer Kahf, an Islamic economist. The main objective is to identify the strengths and weaknesses of each approach while emphasizing how both theories contribute to economic growth and stability. This study uses a qualitative methodology, thoroughly analyzing primary and secondary sources on the works of both economists. Through comparative analysis, this study evaluates the core concepts and assumptions of each theory. The findings show that Keynes' approach is concerned with individual consumption and its impact on savings and economic growth, while Kahf's theory encourages consumption for the collective good in accordance with Islamic principles. The study concludes that combining elements of both theories can offer a more balanced approach, which at the same time enhances social welfare and economic stability.

One of the advantages of the sharia banking business is financing productive sectors that do not contain haram elements. Financing in the micro, small and medium sectors is a sharia banking financing business line, but there is a big risk of bad credit. In recent years, increasing global and domestic economic uncertainty has led to depreciation of the exchange rate, unstable prices of basic commodities, thereby reducing people's purchasing power. This research aims to examine macroeconomic variables such as the exchange rate, inflation and production index as a proxy for GDP towards NPF of sharia banking. The research uses monthly time-series data and the OLS method. The research results show that macroeconomic variables have an influence on NPF. The research implication is that the stability of macroeconomic conditions can maintain people's purchasing power which can influence the NPF level of sharia banking.
