Authors: AlQodsi Enas Mohammed , Jadalhaq Iyad Mohammad , Maknouzi Mohammed El Hadi El , Abdulhay Imad Eldin Ahmad
Published: December 2024

In the intricate realm of contractual law, the condition precluding action serves as a critical safeguard, ensuring that specific legitimate interests are protected within contracts and wills. This research examines this condition’s validity when based on a legitimate motive and for a reasonable duration. The study highlights a case involving an owner who violates this condition by engaging in acts such as sale or gift, raising important questions regarding the legal penalties associated with such violations. The primary objective of this research is to provide a comprehensive understanding of the legal consequences of breaching preventive clauses and to analyze how Egyptian, French, and Palestinian laws protect the interests of the stakeholders involved. The methodology adopted in this study is comparative in nature, involving a thorough analysis of the legal texts from Egyptian, French, and Palestinian laws. This involves a review of legal scholars’ opinions and relevant judicial rulings to highlight the differences in penalties and applications associated with preventive clauses. The findings reveal that both Egyptian and French laws advocate for the invalidity of actions carried out in violation of these preventive conditions. However, there is a divergence among scholars regarding the nature of this invalidity, with some arguing for absolute invalidity while others suggest relative invalidity. Conversely, the Palestinian legal framework prescribes specific penalties, indicating a variance in legislative approaches. The research concludes that the current legislative treatment of preventive conditions is insufficient and requires reform to ensure effective legal protection for affected parties. This leads to policy implications emphasizing the need to strengthen legal frameworks and enhance the clarity of legislative intentions in formulating laws related to preventive clauses. By doing so, the study aims to facilitate the achievement of legitimate interests for parties involved and ensure the enforcement of preventive conditions in a manner that upholds contractual integrity.

Authors: Chen Kuan-Chou , Chen Sam S. , Min Sophia D. , Zhang James Jianhui
Published: December 2024

Ticket revenues are crucial for the financial success of sports teams. To maximize these revenues, teams continuously explore effective ticket promotional strategies. One such strategy includes partial season plans, which mirror bundle offers common across various industries. Another widespread promotional strategy across industries is offering discounted credit (i.e., store credit purchased at a lower price than its face value). However, its application in sports (e.g., providing a $500 credit for tickets at $450) remains limited. Therefore, this study explores critical questions such as: “How effective is offering discounted credit compared to partial season plans?” and “What factors influence ticket promotion preferences?” Consequently, the study employed a 2 × 2 × 2 experimental designs, considering three independent variables: promotion type (discounted credit vs. partial season plans), promotion flexibility (predefined vs. customizable), and the consumer’s distance to the venue (near vs. distant). Results indicated that partial season plans generated significantly higher perceived value and purchase intentions  while presenting lower perceived risks than discounted credit . Promotion flexibility did not significantly influence the three dependent variables , but the distance to the venue did . Both practical and theoretical implications of these findings are discussed.

Published: December 2024

The present research focuses on researching the impact of the diverse communication media that facilitate or develop Student Motivation and Engagement in the educational systems of the states in the Gulf, especially Oman. The main goal of this work is to determine which type of method is most effective in encouraging students in view of cultural and technological factors present in the region. Comparisons using hypothesis testing and structural models which provided higher T value for Technology-Based Communication Methods (TBCM) and Human Face-to-Face Communication Methods (HFtFCM). Next, the research hypothesis H2 that TBCM has a direct positive relationship with SMaE was supported by the following regression coefficients: β = 0.177, t = 4.493; p = 0.000. On the other hand, there was no effect of HFtFCM on SMaE as indicated by a regression coefficient of 0.056 (p < 0.124) for this hypothesis and therefore, this hypothesis was rejected. The analysis using the mediator of Student Perception of Communication Effectiveness (SPoCE) only partly mediates TBCM and SMaE (β = 0.047, t = 3.737, p = 0.000). However, SPoCE was found not to moderate the relationship between HFtFCM and SMaE (β = −0.01, t = 1.125, p = 0.005). The present study underlines the efficiency of TBCM in the area of student engagement, while face-to-face conversation does not play significant part in this process. The obtain results conclude that, the traditional and technological evolution in the Gulf region supports the adoption of TBCM in educational systems. Such approaches support with the technological learning and likings of students, offering greater flexibility and engagement. Educational systems must highlight TBCM to better meet the growing needs of their student, while identifying that face-to-face remains important, though secondary, in energetic motivation.

Authors: Chen Jieyi , Rameli Mohd Rustam Mohd , Cao Hui , Wang Rui , Li Zhi
Published: December 2024

The potential role of self-regulated learning as mediator has been deeply investigated by researchers in recent years. There is limited systematic literature review being done to investigate the role of self-regulated learning as mediator in the students’ academic learning. Therefore, searching studies in the databases WOS (Web of Science), SCOPUS, APA (American Psychological Association) PsycInfo, and ERIC (Education Resources Information Center), the present study conducted a systematic literature review on 32 studies published between 2015 and 2024 to summarize what kind of psychological factors influence students’ academic performance through self-regulated learning and assess the potential mediating role of self-regulated learning in this process. The results show that self-efficacy, emotions and motivation are significant predictors of academic achievement and self-regulated learning act as an important mediator in this relationship. An important implication was obtained that researchers can probe into the influence of specific dimensions of self-efficacy on learning performance through self-regulated learning and the influence of positive emotions such as resilience on learning outcomes with self-regulated learning as mediator.

Authors: Robalinho Joana , Gomes Luís , Mendonça Jorge , Pacheco Luís
Published: December 2024

The principal objective of this article is to gain insight into the biases that shape decision-making in contexts of risk and uncertainty, with a particular focus on the prospect theory and its relationship with individual confidence. A sample of 376 responses to a questionnaire that is a replication of the one originally devised by Kahneman and Tversky was subjected to analysis. Firstly, the aim is to compare the results obtained with the original study. Furthermore, the Cognitive Reflection Test (CRT) will be employed to ascertain whether behavioural biases are associated with cognitive abilities. Finally, in light of the significance and contemporary relevance of the concept of overconfidence, we propose a series of questions designed to assess it, with a view to comparing the various segments of respondents and gaining insight into the profile that reflects it. The sample of respondents is divided according to gender, age group, student status, professional status as a trader, status as an occasional investor, and status as a behavioural finance expert. It can be concluded that the majority of individuals display a profile of underconfidence, and that the hypotheses formulated by Kahneman and Tversky are generally corroborated. The low frequency of overconfident individuals suggests that the results are consistent with prospect theory in all segments, despite the opposite characteristics, given the choice of the less risk-averse alternative. These findings are useful for regulators to understand how biases affect financial decision making, and for the development of financial literacy policies in the education sector.

Authors: Gawronski Carlos Jean , Ningeliski Adriane de Oliveira
Published: December 2024

A constitucionalidade da utilização dos meios atípicos no procedimento executivo tem sido alvo de discussões nos contextos doutrinários e jurisprudenciais, notadamente por ser possível o incurso em direitos fundamentais do devedor, o que implica necessariamente em inobservância à dignidade do próprio executado. Por outro lado, é latente o direito do credor de ver satisfeita sua pretensão ou de levar a efeito pronunciamento judicial face ao devedor. Nesse sentido, a presente pesquisa busca abordar a execução como fase processual, diferenciando os atos expropriatórios em típicos e atípicos, apontando os direitos fundamentais eventualmente violados e os conceituando, contrabalanceando, ainda, os direitos atingidos com a pretensão executória à luz da proporcionalidade, buscando, inclusive, o posicionamento  jurisprudencial quanto à possibilidade de aplicação de tais medidas nos processos de execução. Com isso em foco, buscou-se elaborar o estudo em evidência grandemente com supedâneo no método de abordagem dedutivo, que se justifica haja vista o entendimento de que as medidas atípicas, respeitados os limites é de possível utilização.  Ao final, aponta-se pela constitucionalidade da utilização das medidas, desde que atendidos os critérios de proporcionalidade, adequação e interferência mínima no campo individual do devedor.

Authors: Čukanović Jelena , Petrov Djurdja , Đorđević Sara , Galečić Nevenka , Skočajić Dejan , Vujičić Dragan , Ocokoljić Mirjana
Published: December 2024

This study aims to analyze the impact of climatic variables on the fruiting of blackthorn (Prunus spinosa L.), a species which serves as both a food source and a habitat, offering birds shelter and providing other species with refuge from predators. Accordingly, blackthorn fruiting was recorded through field research in the peri-urban green infrastructure of Belgrade over 18 consecutive years. Urban edges are often the sites of expanding artificial surfaces, habitat fragmentation, and complex land-use transitions, including agricultural intensification and abandonment, which collectively increase pressures on residual semi-natural ecosystems. The integration of floristic sampling, phenological observations, landscape measures, and climatic variables allowed for an exploration of landscapes where blackthorn is successfully incorporated into semi-natural ecosystem remnants within a peri-urban context. The results obtained indicate that the phenological patterns of blackthorn, in response to climate change, demonstrate both adaptability and vulnerability to extreme climatic events during the flowering phase. In 2024, flowering began 6 days earlier than the earliest recorded start date and 43 days earlier than the latest start recorded over the previous 17 years. Regarding the fruiting (phonological) pattern, the average fruit maturation period was 288 days, while in 2024 it occurred 61 days earlier. The statistical significance of earlier fruit maturation and reduced accumulated heat requirements for fruit ripening was confirmed, revealing that as temperatures rise, key phenological events occur earlier with reduced heat accumulation, indicating a dependency on climatic parameters. Understanding the mechanism of phenological patterns is crucial for promoting effective environmental management practices and biodiversity conservation. The study also contributes to the potential application of its findings in designing green spaces in other peri-urban regions, supporting the sustainable development of complex peripheral landscapes by integrating blackthorn into green infrastructure planning.

Authors: Narandžić Tijana , Tanjga Biljana Božanić , Ilić Olivera , Ljubojević Mirjana
Published: December 2024

The aim of this study was to investigate the morphological traits and fragrance-related volatile compounds in three garden rose cultivars from the 'Fragrant Frayla' collection: 'Draga Frayla', 'Jelena Frayla', and 'Lenka Frayla', bred by the private breeding company Pheno Geno Roses. The roses were cultivated under open-field conditions in Temerin, Serbia, without irrigation and chemical treatments. Vegetative and generative properties were assessed in June and September 2023, while headspace volatile extraction and gas chromatography–mass spectrometry (GC-MS) were employed to identify scent-related volatiles. All three cultivars exhibited high ornamental value, with shrub heights ranging from 47 to 67 cm, semi-upright to upright growth habits, double flowers with diameters from 6.6 to 8.2 cm, and petal counts from 35.8 to 83.8. Upon sensory evaluations, 'Draga Frayla', 'Jelena Frayla', and 'Lenka Frayla' were characterized by moderately strong, strong and moderate fragrances, respectively. Volatile analysis detected the presence of phenylethyl alcohol (up to 57.31% in 'Draga Frayla'), terpenoids (a total of 28.2% for citronellol, geraniol, and nerol, found exclusively in 'Jelena Frayla'), and hydrocarbons. Hydrocarbons containing fewer than 30 C-atoms were predominantly found in 'Draga Frayla' (accounting for approximately 25% of the total peak area), while those with more than 30 C-atoms were present at less than 20% in the strongly scented roses. The highest number of volatiles was detected in 'Jelena Frayla', the rose cultivar identified as the most fragrant. The results revealed a correlation between strong fragrance intensity and elevated levels of phenylethyl alcohol and alcoholic monoterpenes, whereas a diverse array of hydrocarbons, rather than their concentration, appeared to enhance scent emission.
The Single-Sex View of Gender and Gender Inequality in a Nigerian Ivory Tower
Authors: Asiazobor Eboiyehi Friday
Published: December 2024

This paper examines gender inequality in a female dominated academic unit in a purposefully selected university in south-western Nigeria. It examines the participants’ understanding of the terms "gender", “men doing gender”, establishes how these perceptions affect male staff and students doing gender, and suggests what can be done to encourage men to participate in gender studies. One of the federal universities in Nigeria that has a Gender Studies Unit was purposively selected. In all, 256 semi structure questionnaires were administered. Out of these numbers, 200 questionnaires were retrieved and analyzed. The results showed that less than 50% (49%) of the respondents defined gender study as the study of men and women. Others (2%) understood gender be the study of men, while 10% had no clear understanding of what gender means. Also, 45% of the respondents said gender is about women and men, 44% stated it was about women, 4% had no clear idea of what gender implies, and 1% of them affirmed that gender is about men. On the perceptions about “men doing gender”, 22% of the respondents were of the view that a negative perception about “men doing gender” would make them lose confidence in themselves, 21.5% stated it would limit their capacity to develop their full potential, and 21% believed it might have adverse effects on men’s career progression. About 20.5% of the respondents affirmed that such a perception would create a lack of interest in this field of study, while 15% affirmed that it would limit their interest in pursuing a career in gender studies. The policy implications of the study were also highlighted and discussed.

Objective

The occurrence of some public health events inevitably endangers medical personnel, and medical personnel, as a special group, have to resume work on time to treat patients. This coronavirus disease-2019 (COVID-19) infection is a good example, and what intensive care unit (ICU) nurses experience as the primary caregivers of critically ill patients after COVID-19 infection is our focus. To explore the work experience of ICU nurses after recovery from COVID-19, and to provide a theoretical basis for the intervention to improve the physical and mental health level and work experience of special workers in public health emergencies.

Methods

We conducted an explorative descriptive study using an inductive thematic analysis. Using the maximum differential sampling method, a semi-structured interview was conducted among 13 ICU nurses suffered from COVID-19 in a tertiary grade A hospital in Qingdao, Shandong Province. This study carried on the theme analysis according to the inductive content analysis method and used MAXQDA 2020 Analytics Pro (VERBI Software GmbH, Berlin, Germany) to manage and summarize the interview data.

Results

After being infected by the virus, SARS-Coronavirus-2 (SARS-CoV-2), the pathogen of COVID-19, the work experience of ICU nurses was extracted from the following 5 themes: (1) Stress and challenge caused by the change of work focus; (2) downsizing, overtime, taking up work with illness, and physical discomfort; (3) dedication and family debt; (4) unknown fear and helplessness; and (5) professional responsibility and sense of benefit.

Conclusions

Under the pressure of COVID-19, ICU nurses face multiple pressures and challenges, and their emotions are complex. We suggest that nursing managers should take corresponding measures to alleviate nurses’ physical and psychological pressure and improve their work experience.

An Examination of Generational Differences in the Sharing Economy: Understanding the Motivations of Idle Asset Owners and Their Impact on Peer-to-Peer Platform Management
Authors: Pelech Pavel , Dědková Jaroslava
Published: December 2024

Background/Purpose

This research examines the dynamics of sharing idle assets on peer-to-peer (P2P) platforms within the sharing economy, focusing on understanding the motivational factors that influence asset owners across generations. Platforms that know what motivates asset owners to enter the sharing economy can more effectively set up and manage marketing communications and gain a competitive advantage.

Methods

A mixed-methods approach has been adopted, which includes both quantitative and qualitative data collection and analysis. The analytical tools used include descriptive statistics, Kruskal-Wallis test, PCA and Welch ANOVA.

Results

We identified four motivation factors. We found out that supply-side generational marketing is appropriate to use if the marketing message targets opportunistic factors (completely new) or social factors; for user-related and social factors, generational marketing is unnecessary, i.e., P2P platforms do not need to distinguish the segment they are targeting with the marketing communication.

Conclusion

This research reveals how generational differences impact motivations to participate in the sharing economy, aiding P2P platform management. It offers a novel, comparative analysis of generational motivators, enriching sharing economy literature and providing practical insights for targeting different generations effectively. Understanding the motivations of idle asset owners is key to managing the business of P2P platforms.

Authors: Lenarčič Božidar , Faganel Armand
Published: December 2024

Background/Purpose

The implementation process of the procurement strategy requires consensus among internal stakeholders. An effective procurement strategy aligns with specific business requirements and accommodates the individual introversion of internal stakeholders. From the latter, we formulate our research question: How is the classification of internal procurement stakeholders designed in the validation of the procurement strategy? The research objective is to present the result in the form of a schematic description and a recommendation for a communication strategy, based on insights from existing theoretical knowledge and the formulation of professional references.

Methods

Nominal Group Technique (NGT) with 13 participants has been applied to analyze viewpoints on procurement functions. To ensure reliability and validity, Cronbach’s alpha test, Spearman coefficient, and t-tests have been used.

Results and Conclusion

Study categorizes internal procurement stakeholders into four groups based on their stance towards strategy implementation: positive, cautiously positive, negatively independent, and negative stake-holders. For each group, we recommend a tailored communication strategy that includes elements such as informing, guiding, motivating, and providing credible data. The research results offer important insights into the dynamics among organizational stakeholders and how communication impacts the success of strategy implementation. We have found that under-standing and adapting to various types of stakeholders are crucial for success, from those highly involved and positively inclined to those with the potential to oppose or hinder implementation. Employing specific communication strategies for each group can significantly enhance the chances of successful implementation and sustainable execution of strategies.

Published: December 2024

This research is a comparative study of the visual identity of batik brands in Indonesia, which aims to identify the differences and similarities in the visual elements of various leading batik brands. Brand visual identity is an important aspect of marketing efforts, because it reflects the image and values that a company wants to convey to consumers. In the context of batik, which is Indonesia's cultural heritage, visual identity is becoming increasingly important as a way to maintain traditional values while remaining relevant in the modern market. The aim of this research is to understand the meaning and dynamics behind the visual identity of a batik brand. This research analyzes the visual symbols of 4 leading batik brands in Indonesia which are analyzed and compared with each other using a qualitative comparative analysis method. The research results show that although many batik brands emphasize traditional elements in their visual identity, there is significant variation in how these brands adapt modern elements to appeal to different market segments. Some brands emphasize traditional motifs with natural colors, while others combine contemporary elements to create a more modern and minimalist impression. Additionally, it was found that brands that focus more on international markets tend to adopt a more universal and simple visual style, compared to brands that focus more on the domestic market which often maintain local uniqueness in their designs

Wear Performance of Wire Arc AM SS 316L Plate For Different Thermal History Regions
Authors: Alrumayh Abdulrahman
Published: December 2024

The development of metal Additive Manufacturing AM processes has become promising for different applications and sectors, especially 316L austenitic stainless steel. Compared with polymer AM which has reached near maturity in process parameters and product properties, metal AM processes have enormous areas for research. Wire Arc AM (WAAM) has a high deposition rate and high heat input, which changes material properties in many ways. For example, wear rate has been studied in AM and WAAM, especially for different materials and parameters. This study aims to investigate the difference between the wear behaviors for different regions in WAAM printed samples. The regions have different thermal cycle histories and different hardness levels. A sample was printed by WAAM and prepared for wear test measurement. There are two selected areas, the inter-layer IL, and the middle of the layer IM which have different thermal cycles. The coefficient of friction COF, COF slope, Friction force, volume loss and mass loss, and hardness were measured and calculated for these two areas. The results show that the IL areas have lower COF, negative COF slope, and lower hardness than other areas. That can be the result of the thermal cycle which affects the residual stress.

Electric discharge machining (EDM) serves as a pivotal technique for the precision machining of materials known for their inherent difficulty in conventional cutting processes. Its capability to fashion blind slots and intricate features in conductive materials, otherwise challenging to fabricate using traditional methods, underscores its significance in modern manufacturing. The effectiveness of Electrical Discharge Machining (EDM) hinges upon a multifaceted interplay of electrical and non-electrical variables, encompassing parameters such as current, voltage, cycle time, and powder concentration. This study delves into the realm of EDM with a specific focus on Powder-Mixed Electro-Discharge Machining (PMEDM), aiming to comprehensively explore and optimize the material removal rate (MRR). The experimental investigation, conducted with and without the incorporation of conductive powder particles into the dielectric medium, scrutinizes the impact on MRR, thereby shedding light on the efficacy of powder integration in enhancing machining efficiency. Furthermore, the study ventures into the realm of computational fluid dynamics (CFD) to simulate and analyze the intricate dynamics of dielectric flow, powder particle behavior, and debris movement within the inter-electrode gap (IEG). These simulations serve as invaluable tools in elucidating the underlying mechanisms governing the machining process, providing insights into the intricate interplay between electrical discharges, fluid flow, and particulate dynamics.
The synthesis of experimental data and simulation results reveals a strong correlation between the inclusion of powder particles in the dielectric medium and the enhancement of machining efficiency, particularly evident in the observed improvements in MRR. The consistency between experimental findings and simulation outcomes underscores the validity and robustness of the study's methodologies and conclusions. In essence, this research not only contributes to the advancement of understanding of PMEDM but also underscores the potential of integrated experimental and computational approaches in optimizing machining processes. By elucidating the intricate dynamics of powder-mixed EDM and its implications on material removal efficiency, this study paves the way for enhanced precision machining in various industrial applications.

Authors: Tressia Gustavo , Tepedino Tiago , Masoumi Mohammad , Ignacio Pereira Juan
Published: December 2024

This work examines defect (spalling) in a railway crossing (frog) removed from a heavy-haul railway after 120 Milling Gross Tons (MGT). The frog was manufactured using standard Hadfield steel. The steel microstructure evolution was analyzed to understand crack initiation and propagation during service. Scanning electron microscopy (SEM), X-ray diffraction, and electron backscattered diffraction (EBSD) methods were employed to characterize microstructural changes near the crack region. Furthermore, local mechanical properties were assessed using nanoindentation tests and sub size tensile tests. SEM analysis revealed that twinning is the primary work-hardening mechanism, with the absence of phase transformation confirmed by XRD. The interaction of dislocation walls and twin structures generated by twinning-induced plasticity increased the local hardness of Hadfield steel up to 8.5 GPa, substantially reducing ductility. Peak broadening of austenite phases was observed, indicating significant crystal defect densities under cyclic loading. Microstructural analysis in defect regions showed that these defects originated from the nucleation and propagation of cracks in grain boundaries with carbides. This investigation demonstrates that the reduced service life of the railway frog is associated with manufacturing process defects and contributes to understanding material deformation mechanisms, aiding in the development of more resilient steels for such applications.

Zinc oxide nanoparticles (ZnO-NPs) are synthesized via a multitude of techniques, resulting in nanoparticles of varying sizes and morphologies that directly influence their antimicrobial efficacy. The objective of this study is to ascertain the particle size and morphology of ZnO-NPs synthesised via the hydrothermal method and to evaluate their in vitro antibacterial effects against Escherichia coli O157, Salmonella Typhimurium, and Listeria monocytogenes, which are important foodborne pathogens. The ZnO-NPs were examined using a scanning electron microscope (SEM). Furthermore, the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and the diameter of inhibition zones were measured against these pathogenic bacteria. The SEM images revealed that the ZnO-NPs exhibited a uniform distribution, with particle sizes ranging between 23 and 25 nm. The MIC and MBC values against the tested strains were found to range from 20.83 to 41.67 µg/mL and between 66.67- 83.33 µg/mL, respectively. In addition, the diameter of inhibition zones were ranged from 15.16 to 16.96 mm. The findings of the study demonstrated that ZnO-NPs s synthesized via the hydrothermal method exhibited antibacterial effects against both Gram-positive and Gram-negative bacteria. In conclusion, the use of ZnO-NPs can facilitate the improvement of the microbiological quality of foods by the inhibition of foodborne patogens.

The objective of this study was to ascertain the impact of ultrasound application on the probiotic characteristics and antioxidant activity of yeasts. In this context, the pH changes, probiotic properties and antioxidant activities of K. marxianus (Km), S. boulardii (Sb) and S. cerevisiae (Sc) were determined by ultrasound application at different durations (5, 15, 30 and 60 minutes at 24 kHz). The lowest pH values were determined for cultures of Km (ultrasound non-applied K. marxianus), Sb-30 (30 min. ultrasound applied S. boulardii) and Sc-5 (5 min. ultrasound applied S. cerevisiae) as 4.48, 5.15 and 5.26, respectively. The hydrophobicity values of the yeast strains varied between 6% and 24%, increased with ultrasound application. Although S. boulardii had the highest tolerance to low pH and bile salts, the resistance of all yeast to low pH and bile salts decreased with ultrasound application. K. marxianus had the least survival under in vitro conditions, but ultrasound application increased survival of K. marxianus strains and slightly affected the survival rate of S. boulardii and S. cerevisiae. Increasing of duration time of ultrasound application resulted higher antioxidant activity and so the highest antioxidant activity was determined for Sb-60. Finally, ultrasound application could be used for the development of hydrophobicity and antioxidant properties of yeast cultures.

A biofilm is a complex matrix formed by microorganisms that includes exopolysaccharides, proteins, extracellular DNA, various enzymes, and the microorganisms themselves. Biofilm cell is a more stable form of microorganism than planktonic cell. Microbial cells attach themselves to the surface after certain signals or changes, colonize to create a more favorable environment for their growth and viability, and secrete exopolysaccharide. This component is the basic matrix of biofilm. The diversity of exopolysaccharides within biofilms varies significantly depending on their specific composition, contributing uniquely to the characteristics of biofilms. This diversity in biofilms underscores the need for targeted control strategies. Biofilms can be beneficial or harmful depending on the situation and where they develop. Accordingly, microbial biofilms have dual effects on health. Biofilms can have both harmful effects on health, such as contributing to antibiotic resistance and persistent infections, while biofilms formed by beneficial microorganisms play a crucial role in enhancing food functionality. Moreover, the formation of biofilm in certain foods can contribute to the enhancement of the product matrix, particularly by improving its texture. In this review, the structures of these biofilms, their basic components, their possible safety concerns, and health benefits are discussed. Moreover, this review deals with biofilm producing bacteria in foods and assesses the prevention strategies for biofilm formation within the food industry.
