Prisoners’ Right to Vote in The Gambia: A Need for Legal Reform?
Authors: Mendy Ousu , Sarr Ebrima
Published: February 2025

Prisoners’ right to vote in The Gambia continues to be a less challenged issue both in practice and in theory in state politics since it regained independence. This research assesses state on prisoners’ right to vote and how this defines the state’s governance system towards prisoners from international human rights perspective. An analysis of this issue in the state since it regained political independence reveals how casual academics and policymakers approach it. This piece, therefore, examines human rights perspective on this right and the state’s obligation to prisoners. The quest for the realization of human rights by the citizenry goes in tandem with the state’s obligation to cease to violate such rights, to ensure their protection, promotion, and respect it. It avails the difference between a right and a privilege and submits that voting is not a privilege but essentially a political right. A qualitative research approach is used by re-examinig and analyzing books, articles and other relevant national and international instruments that are relevant to this work. It finally submits that The Gambia needs to undergo a reformed process in terms of state institutions, and amendment of legal instruments including the Election Act (ius constitutum) to become a law (ius constituendum) that creates equality among the people. The Constitution is both a political and legal instrument, the rights of the prisoners should be empowered by it to address the approach used through the Election Act to limit the political right of prisoners to vote.

Authors: Batóg Barbara , Doszyń Mariusz , Majda Paweł , Pajor Mirosław , Rozkrut Dominik , Rozkrut Monika , Tarczyńska-Łuniewska Małgorzata
Published: February 2025

The impact of metrology on the economy is typically determined on the basis of econometric models that are the modifications of the Cobb-Douglas function and which take into account total factor productivity (TFP). Such models make it possible to examine the cointegration of metrological variables and basic macroeconomic variables. However, this approach could not be used to determine the impact of metrology on the economy in Poland due to too few observations, and thus short time series of the macroeconomic data. The aim of the study presented in this article is to assess the impact of metrology on the economy in Poland by means of the Solow growth model. This model allows a simulation-based approach to analyse the effects of metrology by perturbing TFP. To the authors’ best knowledge, this type of approach has not yet been used to examine the impact of metrology on the economy.
The study demonstrates that a 1-percent increase in the net stock of standards correlates with a 0.35-percent rise in labour productivity, measured as production per employee. These findings align with similar analyses conducted in other countries, contributing to the understanding of metrology’s economic significance.
Legal Certainty of Filing Judicial Review in Tax Dispute Resolution After the Constitutional Court Decision No. 24/PUU-XXI/2024
Authors: Listanti Vidyatika Dwi
Published: February 2025

Judicial review plays a crucial role in ensuring justice and legal certainty in tax dispute resolution, particularly in Indonesia, which adheres to the principle of a rule of law (Recht Staat). The Constitutional Court Decision No. 24/PUU-XXI/2024, however, limits the Directorate General of Taxes from filing judicial reviews, creating challenges for addressing errors in tax dispute decisions. This research uses a normative juridical approach to analyze the legal implications of this restriction, examining its impact on state revenue and legal fairness. Findings indicate that such limitations not only reduce legal certainty but also hinder the correction of judicial errors, potentially causing state financial losses. To address these issues, the study recommends a regulatory model that balances the rights of both taxpayers and tax authorities, fostering fair legal certainty and supporting tax revenue optimization for the State Budget. This regulatory refinement is vital for maintaining justice and fiscal stability in Indonesia.

Authors: Vermudt Alef , Ricardo Pereira Jefferson , Alberto Kanis Luis
Published: February 2025

Aims: Modern restorative dentistry is based on the use of an adhesive system and subsequently a composite resin. The importance of knowledge of the properties and compositions of these systems and their clinical application is one of the critical characteristics for the clinical longevity of composite resin restorations. Simplifying these systems made them very acidic, which raises the hypothesis of restorative failure in the long term. The objective of this research was to evaluate the pH of different types of dental adhesives over three periods of time.
Materials and methods: Three 3M ESPE dental adhesives were tested with different presentations and the pH level was evaluated immediately, 30 and 60 days after their polymerization.
Results: The lowest changes in pH levels were recorded in the groups of the Adper Scotchbond Multi-Purpose control adhesive system. Statistically significant differences were detected between the dental adhesives Adper Single Bond 2 and Universal Single Bond (3M - ESPE) (P<0,05).
Conclusion: Following the results, we concluded that the self-etch group of 1-step and 2-step pre-etched had statistically significant alterations (P<0,05) in the value of pH 30 and 60 days after their polymerization.
Influence of endodontic access cavity shape and direct restoration protocol on the fracture load of molars with mesio-occlusal class II preparation
Authors: Potrich Júlia , Burnett Júnior Luiz Henrique , Fontoura de Melo Tiago André
Published: February 2025

Aims: To evaluate whether the configuration of the endodontic access cavity influences the fracture strength of endodontically treated molars with class II mesio-occlusal (MO) preparation. Materials and Methods: Seventy human mandibular third molars were selected and randomly assigned to seven groups (n = 10). MO cavity preparation and endodontic treatment were standardized, except for the positive control group (GC+: sound teeth). The other groups were classified as GV- = conventional endodontic access and no restoration (negative control); GP- = “bridge” endodontic access and no restoration (negative control); GX- = conventional endodontic access and transfixed fiberglass post without restoration (negative control); GV = conventional endodontic access and restoration; GP = “bridge” endodontic access and restoration; and GX = conventional endodontic access and transfixed fiberglass post with restoration. The specimens were subjected to fracture strength testing on a universal testing machine. The fracture site – either pulp chamber floor or cusp – was inspected. Statistical analysis was performed using ANOVA and Tukey’s multiple comparison test (? = 5%). Results: Means followed by the same letter did not show statistical difference in Tukey’s test (P> 0.05): GC+: 3748A ± 326.7; GV-: 874.6D ± 74.88; GP-: 1378C ± 39.24; GX-: 1593C ± 55.28; GV: 1380C ± 78.84; GP: 1709C ± 154.4; and GX: 2403B ± 385. Conclusions: The combined use of transfixing posts and direct restoration with composite resin increased the fracture resistance of endodontically treated teeth. On the other hand, it was observed that preserving the dental structure in the vestibule-lingual direction during endodontic access did not contribute to an increase in fracture resistance.

EM TORNO DA SUBJETIVIDADE AUTÔNOMA: CRISE E DESAFIOS CONTEMPORÂNEOS
Authors: Hermann Nadja Mara Amilibia
Published: February 2025

This article discusses autonomous subjectivity, as the central core of concerns about education. To contextualize the problem, we first revisit the consideration of modern subjectivity, which establishes a form of relationship between man and himself and the world, based on rational self-determination, which supports the classical idea of autonomy. In a second movement, we use Honneth's (2009) concept of decentered autonomy, reinterpreted in terms of a theory of intersubjectivity, which requires the management of drives and the reorganization of life, taking into account the moral demands of the social context. This concept is complemented by Bieri's (2013) contribution regarding the inner dimension of autonomy, according to which becoming autonomous implies becoming dignified, which allows us to lead our lives more fully. Next, in line with the demand for a refined moral sensitivity capable of establishing decentered autonomy, we suggest an ethical-aesthetic education.

Sustainable tourism integrates economic, social, and environmental aspects of sustainability. This study investigates the local community's perceptions of tourism development impacts and factors influencing support for sustainable tourism and destination sustainability within Stara Planina Nature Park. Using a Structural Equation Modeling (SEM) approach, using multiple hypothesized relationships across key dimensions, including economic, environmental, social, and infrastructural impacts are examined. The findings highlight the importance of socio-cultural factors in fostering support, while also recognizing the negative impact of environmental and infrastructural concerns. Socio-cultural impacts significantly and positively influenced support for sustainable tourism and destination initiatives, highlighting the role of cultural exchange, tradition preservation, and community identity in garnering local support. These findings align with previous studies, emphasizing the importance of perceived socio-cultural benefits in fostering community backing for tourism development. Effective STD management requires the active involvement of local stakeholders to ensure alignment with local values and environmental goals. Policymakers should focus on enhancing socio-cultural benefits, addressing infrastructural challenges, and effectively communicating economic advantages. Limitations of the study include its cross-sectional design, suggesting the need for longitudinal research to better understand the evolving impa ct of tourism.

The paper examines how and in what manner reader comments on media posts correspond with the text, as well as the content of those comments, their intended recipients, linguistic expressions used, and how they convey their stance on a particular topic/phenomenon/event and/or individual. Reader comments on media posts illustrate the extent to which the freedom they enjoy in the digital space can lead to discriminatory behavior, aggression, and various forms of verbal violence. For this reason, in this paper, we focus on the phenomenon of commenting on media content. The focus of this study is a current and pervasive phenomenon concerning audience comments on media content in the digital sphere. For the purposes of this research, comments on texts of the same topic, published on the portal and Facebook page of one media outlet, were analyzed for both 2020. and 2022. This research aims to provide an authentic portrayal of the correlation and interaction between media content and the comments that readers write underneath it. Special attention is given to the occurrence of hate speech, with a particular emphasis on sexism, discrimination against LGBT individuals, and stereotypical portrayals of the individuals being commented on. The research results indicate that the woman who were the subjects of the posts in the comments were either ignored or depicted extremely negatively.
"Black chronicle" and ethics in the press in Serbia 100 years ago and today
Authors: Cvejić Bojan
Published: February 2025

The public's attention in crime news and headlines about accidents and tragedies is not a trend of the new age. News from the so-called "crime chronicle" has been published in the media since the beginning of journalism. Although there is often no public interest in them, but rather a predominance of public curiosity, "black news" has always found its way to the audience through the media. Nowadays, especially in the media in Serbia, examples from this thematic area are most commonly cases in which journalists cross professional boundaries and violate ethical standards. Based on experience and practice in recent decades, numerous rules regarding reporting on criminal acts and personalities, who are direct or indirect actors in such events, have been established through media ethical codes and competent laws. The aim of this research is to establish what has changed in the Serbian media in this regard compared to a hundred years ago, when ethical codes were in their early stages without guidelines and precise rules. The sample includes three daily newspapers: Pravda, Vreme, and Politika from the period between February 1 and February 29, 1924, as well as the daily newspapers Kurir, Večernje novosti, and Politika from the period between February 1 and February 29, 2024.
Media and information literacy of elderly individuals: A prerequisite for participation in the digital era
Authors: Trninić Dragana
Published: February 2025

Thanks to the continuous development of information and communication technologies (ICT), there are significant opportunities for easier everyday activities and problem-solving, particularly suitable for the elderly, from home delivery to bill payment to a higher-quality information system. One of the challenges of the modern digital age is organizing a society based on respect for human dignity, freedom, democracy, equality, where everyone can live and age without discrimination. Digital transformation potentially influences these processes and challenges. Given that almost half of individuals over 65 years old in Bosnia and Herzegovina (BaH) are in the digital divide, meaning they do not use the internet or digital services (CRA, 2021), this study focuses on this population, their media and information literacy (MIL). The aim is to determine the level of knowledge and skills of older adults in the field of MIL, which media they use and why, whether they trust them, and their attitude towards media and media content. The research was conducted in Republic of Srpska using the semistructured interview method with 15 participants. The results indicate an insufficiently developed system of personal MIL competencies among the participants and the need for education of the elderly in this area, especially in the segment of digital competencies.

For the last several decades, internet has penetrated so deep in our everyday life and became the very essence of our being as well as of the way we function, so the question arises whether the internet has become an integral part of our life, or its users are just the factors of the global network system. Many scientists are trying to answer the question whether the moment of the internet taking over the role of the global consciousness is close. Artificial intelligence is used in more aspects each day of our lives, and the present testifies just how much people rely on the symbiosis with elements of technology with one foot in the virtual world. There are several directions of reflection regarding the future of interaction or symbiosis between man and machines. This paper deals with these concepts, gives the review of theories addressing the same issue and tries to explain the idea why the total control of the machine over the humankind is basically - not plausible.
Structural optimisation of planetary gearbox components
Authors: Marinkovic Aleksandar , Sedak Miloš , Lazović Tatjana , Rosić Maja
Published: February 2025

The high-speed reduction in a relatively small space, coupled with a torque load capacity larger than that of any other standard transmission, positions planetary gear systems as one of the most vital components in gearing applications today. Structural analysis of a gear train is conducted using CATIA software, employing strain full tensor distribution analysis through Finite Element Method (FEM). The analysed natural frequencies and vibration modes of each component provide essential information for fine-tuning resonances away from the assembly's operating speeds. Based on these results, component dimensions are optimized using CATIA's optimizer module to achieve a structurally compact gearbox design. The minimization of gearbox mass serves as an objective function, with gear dimensions as variable parameters constrained by ultimate bending tooth root stress, safety factors, and critical frequencies expressed as inequalities. Structural optimization results are presented in tables, comparing initial natural frequencies with those obtained from the optimized solution. The final optimized design for each gear train component is also presented and discussed in the paper's concluding section. In conclusion, the paper outlines its primary objectives, summarizing key findings and proposing new ideas for further research to enhance and optimize planetary gear transmissions in practical applications.
Evaluation of aerodynamic coefficients of supercritical airfoil NASA sc(2) 0712: A comparative study of 2D and 3D flow models with experimental validations
Authors: Šukunda Teodora , Svorcan Jelena , Ivanov Toni
Published: February 2025

This study presents a comparative numerical analysis of 2D and 3D compressible, turbulent flows around the supercritical airfoil NASA sc(2) 0712 at Mach number M = 0.5 using the finite volume method implemented in ANSYS Fluent, focusing on the estimation of drag coefficients in relation to existing experimental data. In addition, different types of computational grids and turbulence models are tested. The investigation aims to highlight the discrepancies observed between the two modeling approaches and their implications for aerodynamic performance predictions. Through rigorous numerical simulations and validation against experimental results, we demonstrate that 2D models often yield overestimated drag values due to simplified flow assumptions. In contrast, 3D simulations provide a more accurate representation of fluid behavior, resulting in closer alignment with experimental findings. By performing spatial computations of turbulent flow around a supercritical airfoil, it is possible to reduce the relative error of drag coefficients by less than 10%.

Authors: Tolentino San , Mírez Jorge
Published: February 2025

In the present work, the objective is to determine the Mach number and static pressure flow field behavior for off-design planar nozzle geometries with divergent angles of 1.21° (model A1) and 10.85° (model B1). ANSYS-Fluent R16.2 code was employed, and the RANS model and SAS turbulence model were applied to simulate in 2D the viscous flow field for the nozzle pressure ratio range of NPR 2.49 to 8.91. For model A1, in the divergent, the shock train is present, and the lateral pressure loads show fluctuations; in the centerline, the velocity is in the range of Mach 0.849 to 1.405. For model B1, the shock train is not present in the divergent, and the lateral pressure loads show flow separation; in the centerline, it is in the range of Mach 0.849 to 1.991. The flow velocity at the exit of the A1 model nozzle reaches Mach 1.357, which is 52.2% lower with respect to the B1 model, which has Mach 2.066. However, for the supersonic jet in the region of the atmosphere, the A1 model reaches Mach 2.967, which is 14.9% higher than with respect to the B1 model, which has Mach 2.522.

Authors: Vakulenko Daria , Mileikovskyi Viktor
Published: February 2025

The use of exhaust air heat recovery systems is crucial for modern energy-efficient ventilation. In private homes, space limitations often hinder centralized systems, making decentralized regenerative ventilation an effective alternative. These systems feature small equivalent diameter cells, requiring refined heat transfer coefficients for accurate efficiency assessments. An experimental setup was constructed to study heat transfer in tubes with diameters of 3 mm and 5 mm, leading to the development of a Nusselt number formula to determine the convective heat transfer coefficient precisely. To minimize environmental interaction, suitable thermal insulation thickness was applied. Modeling channels with 3 mm and 9 mm diameters revealed temperature distribution and relationships between the Nusselt and Grashof numbers. A comparative analysis of the Nusselt number formula was conducted, aiding in evaluating heat transfer coefficients for tubes with internal diameters from 3 to 8 mm, along with the construction of a diagram for engineering applications.
Altered levels of sphingolipid metabolites in serum of locally advanced rectal cancer patients: a pilot study
Authors: Bjelanovic Jasna
Published: February 2025

ABSTRACT
Background: Altered sphingolipid levels might contribute to rectal cancer development, progression and therapy response due to their regulation of different biological processes including apoptosis. This study aimed to examine the diagnostic and predictive potential of sphingolipids in serum of patients with rectal cancer, as well as their association with apoptosis score in tumor tissue. Methods: Ceramide (CER) and sphingomyelin (SM) serum levels were analyzed in 22 patients with locally advanced rectal cancer and 24 healthy individuals by ultrafast liquid chromatography coupled with tandem mass spectrometry. The expression of pro-apoptotic BAX (BCL2 associated X, apoptosis regulator) and anti-apoptotic BCL2 (BCL2 apoptosis regulator) was analyzed in tumor and corresponding healthy tissue samples of patients by quantitative real-time PCR. Results: Significantly lower serum levels of C18 CER, C22 CER, C24 CER, C18 SM and C24 SM were observed in patients than in controls (P<0.05). For C20 CER, C22 CER and C24 CER a positive correlation with pro-apoptotic status of tumor tissue was found (r=0.619, P=0.018; r=0.694, P=0.006 and r=0.601, P=0.023, respectively). Conclusions: These results support the involvement of sphingolipids in rectal cancer. However, to clarify the diagnostic and predictive potential of sphingolipid metabolites, further studies including a larger cohort of subjects are needed.

In order to assess the profitability of mill companies and identify influencing factors, 30 companies operating in the Republic of Serbia from 2010 to 2019 were analyzed. The profitability of these companies was measured using the ROA indicator. Internal factors influencing profitability included liquidity, indebtedness, financial leverage, asset structure indicator, total asset turnover ratio, and Zscore, while external factors considered were the gross domestic product growth rate and inflation. The analysis of the collected financial data began with the application of descriptive statistics to gain a clearer understanding of their business performance and the economic environment in which they operate. Following the descriptive statistical analysis, a panel regression method was employed to determine the impact of the observed internal and external factors on the profitability of milling companies. Based on the estimated panel regression model, it was found that the statistically significant factors influencing the profitability of the observed companies include liquidity, financial leverage, tangibility, total asset turnover ratio, Z-score, and inflation. Among these significant factors, only the Z-score had a positive impact on profitability, while the other factors negatively affected the profitability of the observed companies.
Strategic management as an instrument for the development of sustainable tourism in Serbia
Authors: Milačić Dragan
Published: February 2025

The development of modern tourism, by the principles of sustainable development and ecological responsibility, is subject to numerous doubts, consequences, and abuses. Ecological sustainability implies harmonious development with environmental processes, biological diversity, and resources. Despite the tendency to develop tourism by the principles of environmental responsibility, sustainable development implies the assumption of responsibility by all who are involved in the development of tourism in any way. The tourism industry of Serbia, as well as all institutions in the field of tourism, is faced with the task of establishing sustainable and responsible development to preserve all essential values of the natural and social environment as part of the tourist product and achieve the necessary balance in meeting the needs of tourists. Environmental management should provide answers on ways to meet consumer demands and the ecological requirements of the environment. Organizations that, in creating their strategies, are guided by the current requirements imposed by the natural environment, find new opportunities to attract consumers and develop their business.

As competition for water demand increases in all life sections, the agricultural sector has observed a gradual decrease in water consumption. In order to sustain or enhance agricultural productivity, innovative irrigation methods, like surface and subsurface drip irrigation systems, enhance the efficiency of water utilization compared to conventional systems. Multiple models have been established to forecast the dimensions of moisture distribution, which have significance for constructing an efficient drip irrigation system. This study evaluates the performance of surface and subsurface drip irrigation systems using the HYDRUS-2D model to predict soil moisture distribution under varying conditions of time, emitter spacing, and emitter depth. The results indicate a high level of agreement between simulated and observed moisture distributions, demonstrating the reliability of HYDRUS-2D as a predictive tool for modeling soil water dynamics. The study demonstrates the effectiveness of HYDRUS-2D in simulating soil moisture distribution for surface and subsurface drip irrigation systems under varying conditions of time, emitter spacing, and depth. Subsurface irrigation at 20 cm depth showed the highest simulation accuracy, with RMSE as low as 0.008798 and R² up to 0.9839, particularly at shorter intervals. Closer emitter spacing (20 cm) provided more uniform moisture distribution, while increased spacing (40 cm) led to less consistent patterns. Emitters placed at 20 cm depth achieved the optimal balance between precision and efficiency by minimizing evaporation and effectively targeting the root zone. These findings underline the utility of HYDRUS-2D as a reliable tool for optimizing drip irrigation design, improving water-use efficiency, and supporting sustainable agricultural practices in water-scarce regions.
Numerical Analysis of Tunnel Displacement Profiles with Pipe Umbrella Support: Parametric Study of Selected Umbrella Parameters

Published: February 2025

Ensuring the stability of tunnels excavated in weak rock masses poses significant engineering challenges, particularly in controlling deformations of the excavated rock-mass. This research represents a conceptual analysis aimed at exploring the effectiveness of pipe umbrella support systems across various configurations, without being tied to a specific tunnel project. The study also investigates the possibility of using simplified Finite Element Method (FEM) modelling for such purpose. Specifically, analysis focuses on findin the correlation between selected design parameters and support system performance. A numerical model incorporating the Hoek-Brown failure criterion, was employed to simulate the interaction between the pipe umbrella and surrounding rock mass. Key parameters analyzed include the length of the pipe umbrella segments, overlap between segments, and the stiffness of the pipe umbrella material. The results demonstrate the potential in reducing both radial and axial displacements as the segment length of the pipe umbrella and overlap increase, with diminishing returns observed for higher umbrella’s stiffness values. This study despite being based on theoretical case scenario also highlights the practical advantages of a simplified axisymmetric FEM model for conducting parametric analyses, significantly reducing computational complexity while maintaining sufficient accuracy.
