The Effects of Board Diversity on Korean Companies’ ESG Performance
Authors: Jeyhunov Ahmet , Kim Jong Dae , Bae Seong Mi
Published: January 2025

This paper explores the effect of board diversity on environmental, social, and governance (ESG) performance in Korean-listed firms using regression analysis. Our findings reveal that an increased board size significantly correlates with higher ESG scores when combined with other board diversity dimensions. The presence of female directors on boards was found to have a significant effect on environmental and social components of ESG performance. Age diversity exhibits a negative association with ESG scores, emphasizing potential disruptions from intergenerational differences. Foreign directors show no significant impact on ESG performance, suggesting that country-specific contextual factors may limit foreign directors’ influence on boards. The proportion of highly educated directors positively affects the overall ESG performance, aligning with resource dependence and agency theories. Overseas-educated directors play a crucial “bridging” role in adapting sustainable innovations overseas, positively influencing ESG performance. In conclusion, this study provides empirical evidence of the complex relationships between board diversity dimensions and ESG performance in the Korean context. These findings guide stakeholders in shaping inclusive and effective board structures for optimal corporate sustainability.

Authors: Zachariou Marios , Adenuga Adewale Henry , Jack Claire
Published: January 2025

Climate change and environmental degradation present significant and ongoing challenges to the agricultural sector. Formal education has been shown to equip farmers with the knowledge and skills needed to improve their environmental performance and address these problems. However, there is a notable gap in the literature regarding a comprehensive review of how farmers’ education impacts environmental outcomes. This paper aims to bridge that gap by synthesizing the results of studies exploring the role of education in explaining environmental performance. To this end, we conducted a systematic review of the existing literature. We organised the resulting 127 studies into thematic groups to provide corresponding overviews. Subsequently, we conducted a vote-count analysis of the reported direction and statistical significance of effects and associations between education and environmental performance. We observe that reporting at the variable level rather than the overall study level may have led to the importance of education for specific groups of farmers being overlooked. We suggest that the way education variables are constructed can influence the results of studies, leaving the results of vote-count analysis open to interpretation. The findings of the review provide the requisite evidence base to inform the development of effective policy measures that enhance the sustainability of farming.

Heavy metal (HM) pollution has become a major environmental concern due to increased anthropogenic activities. The persistence and toxicity of HMs pose significant risks to ecosystems, biodiversity, and human health. This review highlights the pressing issue of HM contamination, its impact on ecosystems, and the potential risks of bio-magnification. Addressing these issues requires sustainable and cost-effective solutions. Among various remediation strategies, phytoremediation stands out as a promising green technology for mitigating environmental damage by using plants to extract or detoxify contaminants. A key challenge in phytoremediation, however, is the management of large volumes of contaminated biomass. This study explores the integration of phytoremediation with biofuel production, which not only addresses biomass management but also offers a sustainable solution within the framework of the circular economy. The dual role of specific plant species in both phytoremediation and biofuel production is evaluated, providing reduced environmental waste, lowering remediation costs, and promoting energy security. Future advancements in plant engineering, biotechnology, and process optimization hold the potential to enhance phytoremediation efficiency and biofuel yields. Expanding research into metal-tolerant, high-biomass crops can further improve scalability and economic feasibility. The review also critically assesses challenges such as the safe handling of contaminated biomass, sustainability concerns, and existing research gaps. By merging environmental remediation with bioenergy production, this interdisciplinary approach presents a viable pathway toward sustainable development.

Published: January 2025

In recent years, wind energy has emerged as one of the fastest-growing green technologies globally, with projections indicating that decommissioned wind turbine blades (WTBs) will accumulate to millions of tons by the 2030s. Due to their thermosetting nature and high glass/carbon fiber content, the efficient recycling of WTBs remains a challenge. In this study, we utilized solid-state shear milling (S3M) to produce a fine WTB powder, which then underwent surface modification with a silane coupling agent (KH550), and we subsequently fabricated WTB-reinforced polypropylene (PP) composites with enhanced mechanical performance through solid-state stretching. The stretching-process-induced orientation of the PP molecular chains and glass fibers led to orientation-induced crystallization of PP and significant improvements in the mechanical properties of the PP/WTB@550 composites. With 30 wt. % WTB content, the PP/WTB@550 composite achieved a tensile strength of 142.61 MPa and a Young’s modulus of 3991.19 MPa at a solid-state stretching temperature of 110 °C and a stretching ratio of 3, representing increases of 268% and 471%, respectively, compared to the unstretched sample. This work offers both theoretical insights and experimental evidence supporting the high-value recycling and reuse of WTBs through a cost-effective, environmentally friendly, and scalable approach. Due to the enhanced mechanical properties of the PP/WTB composite and the intrinsic waterproofing and corrosion resistance of PP, it is hoped that such a composite would be used in road engineering and building materials, such as geogrids, wall panels, floor boards, and floor tiles.

Published: January 2025

In the 21st century, the increasing complexity and uncertainty of the global economy have heightened the need for accurate economic forecasting. Per capita GDP, a critical indicator of living standards, economic growth, and productivity, plays a key role in government policy-making, corporate strategy, and investor decisions. However, predicting per capita GDP poses significant challenges due to its sensitivity to various economic and social factors. Traditional methods such as statistical analysis, regression, and time-series models have shown limitations in capturing nonlinear interactions and volatility of economic data. To address these limitations, this study develops a per capita GDP forecasting model based on deep learning, incorporating key macroeconomic variables—the Consumer Price Index (CPI) and unemployment rate (UR)—to enhance predictive accuracy. This study employs five deep-learning regression models (RNN, LSTM, GRU, TCN, and Transformer) applied to real and placebo datasets, each incorporating combinations of CPI and UR. The results demonstrate that deep learning models can effectively capture complex, nonlinear relationships in economic data, significantly improving predictive accuracy compared to traditional models. Among the models, the Transformer consistently achieves the highest R-squared and lowest error values across various metrics (MSE, RMSE, and MSLE), indicating its superior ability to model intricate economic patterns. In addition, including CPI and UR as additional predictors enhances model robustness, with the TCN and Transformer models showing particularly strong performance in capturing short-term economic fluctuations. The findings suggest that the deep learning models, especially the Transformer, offer valuable tools for policymakers and business leaders, providing reliable GDP forecasts that support economic decision-making, resource allocation, and strategic planning. Academically, this study advances the understanding of deep learning applications in economic forecasting, particularly in integrating significant macroeconomic variables for enhanced predictive performance. The developed model is a foundation for informed economic policy and strategic decisions, offering a robust and actionable framework for managing economic uncertainties. This research contributes to theoretical and applied economics, providing insights that bridge academic innovation with practical utility in economic forecasting.
No Planet-B Attitudes: The Main Driver of Gen Z Travelers’ Willingness to Pay for Sustainable Tourism Destinations
Authors: de Araújo Arthur Filipe , Andrés-Marques Isabel , López Moreno Lorenza
Published: January 2025

With consumers becoming increasingly aware of the effects of human activity on the environment, tourism products and destinations are increasingly marketed as sustainable and socially responsible. As most sustainable practices lead to additional costs, and tourists’ decisions tend to be price sensitive, achieving sustainability goals necessarily involves understanding how much more tourists are willing to pay for sustainable practices as well as the antecedents of such willingness to pay (WTP). The present study aims to advance knowledge on the antecedents of WTP for sustainable destinations (WTP-4-SD), for which it builds on previous studies employing the Theory of Planned Behavior (TPB) and the New Environmental Paradigm (NEP). In this context, a theoretical model involving ecotourism attitudes, environmental beliefs, climate change-related risk perceptions (CC-RRP), environmental concern during trip (ECDT), and sustainable consumption behavior (SCB) as antecedents of WTP-4-SD is proposed. The model was tested based on data collected through an online survey from a sample of 847 Spanish and Portuguese Gen Z travelers and analyzed through Structural Equations Modeling (SEM). The findings suggest that a cohesive set of attitudes and beliefs regarding the man–nature relationship, the risks of climate change, and the role of tourism—which have been labeled “No Planet-B Attitudes”—is the main driver of WTP-4-SD. The effects of SCB and ECDT on WTP-4-SD have also been confirmed—although the latter is quite small—as well as those of No Planet-B Attitudes on both. The findings bring about insights into young travelers’ attitudes towards nature and the role of tourism in sustainable development, as well as useful implications for sustainable tourism planning and marketing.
Applying the PRiSM™ Methodology to Raise Awareness of the Importance of Using Sustainable Project Management Practices in Organizations
Authors: Moutinho Ana , Sousa Paulo , Tereso Anabela
Published: January 2025

Sustainability has become crucial in today’s business landscape. Customers, suppliers, partners, and investors are increasingly demanding that companies be aware of their impacts on the environment and society. Achieving sustainability in business operations, including social, economic, and environmental aspects, is one of the major challenges for companies today. Integrating sustainability into project management fosters the development of more sustainable and responsible projects, considering environmental, social, and economic aspects. This integration allows for benefits such as risk and operational cost reduction, strengthening of the company’s reputation, and gaining stakeholders’ trust. This study takes an exploratory approach, focusing on a pilot test to investigate how the PRiSM™ (Projects Integrating Sustainable Methods) methodology can be applied in a business context to assess the level of maturity of sustainable project management practices and thus raise awareness of the importance of these issues. PRiSM™ was developed by GPM® Global (Global Project Management, Lees Summit, MO, USA) in 2013 to help organizations integrate project processes with sustainable initiatives and it is based on the P5 Standard, which incorporates tangible tools and methods to manage the balance between finite resources, social responsibility, and delivery of sustainable project outcomes. Based on the PRiSM™ methodology and the P5 Standard (2nd Edition), a comprehensive questionnaire was developed under the Portuguese Project Management Observatory® to assist companies in assessing their performance in terms of sustainable practices, resulting in a sustainable maturity level. The questionnaire aimed to evaluate companies in four impact categories: product/process impacts, social impacts, economic impacts, and environmental impacts. The results, obtained from 30 respondents, indicated that the majority of organizations achieved medium-level ratings, with an overall average of 65%. However, some still showed unsatisfactory performance, with a minimum score of 14%, indicating there is still a long way to go for the full integration of sustainability. Based on participants’ feedback, the study found that many recognized the importance of sustainability but were unaware of how to integrate sustainability practices into their project management activities, highlighting the importance of promoting education and raising awareness about sustainable project management practices. The findings, while based on a limited sample, provide valuable initial insights into the potential of PRiSM™ to foster sustainability in project management. This research underscores the need for further studies to expand and validate these preliminary conclusions.

Published: January 2025

The transformation of hypoglycin A (HGA), hypoglycin B (HGB), and methylene cyclopropyl glycine (MCPrG) in ruminal fluid batch cultures was investigated, and the effect of these toxins on the batch culture microorganisms using microbial metabolites was measured. An experiment was conducted using ovine ruminal fluid batch cultures and the ANKOM RF Gas Production System over four runs, each with an incubation period of 48 h. The fermenters contained 200 mg of (i) a substrate mixture (80% cellulose, 20% starch; CSM), (ii) CSM and 1.5 mL of a solution of pure toxins (a mixture of 500 ng/mL HGA and MCPrG each; PCM), or (iii) CSM and 100 mg sycamore maple seeds (SMS). Each fermenter contained 30 mL of inoculum (ruminal fluid and buffer, 1:2 v/v). For control, autoclaved ruminal fluid was incubated with CSM, PCM, and SMS, respectively. Samples were taken from the liquid phase of the fermenters and analyzed using liquid chromatography–tandem mass spectrometry (LC/MS-MS) for sycamore maple toxins and metabolites. Microbial activity was assessed using gas production, short chain fatty acids, and NH3 concentration. Additionally, pH and redox potentials were measured. In PCM, HGA and MCPrG concentrations rapidly decreased (p < 0.05), and were not measurable anymore after a 24 h incubation period. In SMS, the initial concentrations were 4.7 ± 1.4 µg/mL HGA, 19.9 ± 5.41 µg/mL HGB, and 1.2 ± 0.33 µg/mL MCPrG. In SMS, HGA increased in 24 h, coincidently to a decrease in HGB concentration (p < 0.05). We modeled a rapid conversion of HGB to HGA, accompanied by progressive HGA transformation. The concentration of MCPrG was constant until 4 h and decreased afterwards (p < 0.05). In SMS incubations, HGA and MCPrG concentrations of 5.6 ± 1.5 and 0.32 ± 0.090 µg/mL remained after 48 h, respectively. The HGB to HGA conversion and transformation of HGA and MCPrG also occurred in autoclaved ruminal fluid. Gas production and microbial metabolite concentrations were higher in SMS compared to CSM and PCM (p < 0.05), as the seeds were used as an additional substrate by the batch culture microorganisms.
Negative Association of Gulf War Illness Symptomatology with Predicted Binding Affinity of Anthrax Vaccine Antigen to Human Leukocyte (HLA) Class II Molecules
Authors: James Lisa M. , Georgopoulos Apostolos P.
Published: January 2025

Background: Anthrax is a serious disease caused by Bacillus anthracis (B. anthracis) with a very high mortality when the spores of B. anthracis are inhaled (inhalational anthrax). Aerosolized B. anthracis spores can be used as a deadly bioweapon. Vaccination against anthrax is the only effective preventive measure and, hence, the anthrax vaccine was administered to United States (and other) troops during the 1990–91 Gulf War. However, the anthrax vaccine is not harmless, and the anthrax vaccination has been linked to the occurrence and severity of Gulf War Illness (GWI), a debilitating Chronic Multisymptom Illness (CMI). We hypothesized that this is partly due to the combination of two factors, namely (a) the cytotoxicity of the antigen (anthrax Protective Antigen, PA) contained in the vaccine, and (b) the Human Leukocyte Antigen (HLA) genotype of susceptible vaccinees, reducing their ability to make antibodies against the cytotoxic PA. Method: Here, we tested this hypothesis by determining the association between severity of GWI symptoms in 458 GW veterans and the overall strength of the binding affinity of the PA epitopes to the specific six Human Leukocyte Antigen (HLA) Class II alleles carried by each individual (two of each of the HLA-II genes: DPB1, DQB1, DRB1), responsible for initiating the process of antibody production in otherwise immunocompetent individuals, estimated in silico. Results: We found that the severity of GWI symptomatology was negatively and significantly correlated with the strength of the predicted binding affinity of PA peptides to HLA-II molecules (r=−0.356, p<0.001); the stronger the overall binding affinity, the weaker the symptoms. Since the binding of a peptide to an HLA-II molecule is the first and necessary step in initiating the production of antibodies, the findings above support our hypothesis that the severity of GWI symptomatology is partly due to a lack of HLA-II protection. Conclusions: Reduced HLA protection against the toxic anthrax vaccine may underlie GWI.

Published: January 2025

The electric traction drive is increasingly being applied as a device providing traction force on driving wheels. This is due to its reliable torque transmission to the driving wheels, step-less regulation of the traction force on the driving wheels depending on the driving conditions, and increased design capabilities. In terms of power, the electric traction drive has maximum torque at low speeds, which internal combustion engines lack. This property of the electric drive is not applied in urban vehicles, as not all passengers are comfortable with intensive acceleration. In modern vehicles with an electric traction drive, the maximum acceleration can be limited by software, which is the focus of this study. This paper aims to develop an algorithm capable of recognizing when the permissible longitudinal acceleration exceeds the limit and generating an action to maintain the acceptable acceleration level. The electric traction drive of a large-class electric bus was used as a control object. An algorithm and a control law are hereby developed, which reduce longitudinal acceleration using PI control. Both simulation modeling and full-scale tests on the electric bus were carried out to evaluate the performance and efficiency of the algorithm. In this paper, the authors also introduce the cumulative velocity concept and prove the operability and efficiency of the developed method.

Published: January 2025

Cytology is an exam frequently used as a diagnostic technique to evaluate animal oral lesions. However, the retrospective studies published comparing cytology and histology in oral pathology are scarce. This study aimed to determining the association between diagnostic cytology and histopathology in neoplastic and non-neoplastic samples from oral cavity lesions of dogs and cats. Cytological and histological samples (n = 103) of oral lesions from 70 dogs and 33 cats collected over 12 years were compared in terms of agreement, considering the histopathology as the gold standard. Of 103 specimens, 78 were classified as neoplastic, and 25 were non-neoplastic. The sensitivity, specificity, and accuracy of cytology in neoplastic and non-neoplastic lesions were 84.6%, 96.0%, and 87.4%. Of the overall 103 cases, 75.7% (n = 78) were neoplastic and revealed an agreement that was complete in 64.1% (n = 50) and partial in 17.9% (n = 14) samples, and the remaining 17.9% (n = 14) revealed disagreement; regarding the non-neoplastic diagnoses (24.3%, n = 25) the agreement was complete in 68.0% (n = 17), partial for 20.0% (n = 5) samples, and the remaining 12.0% (n = 3) revealed disagreement. A statistical association between neoplastic cases and agreement was obtained (p < 0.0001). The high agreement verified between the cytological and histopathological diagnoses emphasizes the role of cytology as the first approach method to an oral lesion in dogs and cats.

Published: January 2025

Battery modelling is essential for optimizing the performance and reliability of Unmanned Aerial Vehicles (UAVs), particularly given the challenges posed by their dynamic power demands and limited onboard computational resources. This study evaluates two widely adopted Equivalent Circuit Models (ECMs), the fixed resistance model and the Thevenin model to determine their suitability for UAV applications. Using the Specific Hybrid Pulse Power Characterization (SHPPC) method, key parameters, including Open Circuit Voltage (OCV), internal resistance (Ri), polarization resistance (R1), and polarization capacitance (C1), were estimated across multiple states of charge (SOC). The models were analyzed under nine parameterization scenarios, ranging from fully average parameters to configurations where selected parameters were tied to SOC. Results indicate that the Thevenin model, with selective SOC-dependent parameters, demonstrated superior predictive accuracy, achieving error reductions of up to 4.26 times compared to the fixed resistance model. Additionally, findings reveal that modelling all parameters as SOC-dependent is unnecessary, as simpler configurations can balance accuracy and computational efficiency, particularly for UAVs with constrained BMS capabilities.

Published: January 2025

The effective administration of lithium-ion batteries is key to the performance and durability of electric vehicles (EVs). This systematic mapping study (SMS) thoroughly examines optimization methodologies for battery management, concentrating on the estimation of state of health (SoH), remaining useful life (RUL), and state of charge (SoC). The findings disclose various methods that boost the accuracy and reliability of SoC, including enhanced variants of the Kalman filter, machine learning models like long short-term memory (LSTM) and convolutional neural networks (CNNs), as well as hybrid optimization frameworks that combine Grey Wolf Optimization (GWO) and Particle Swarm Optimization (PSO). For estimating SoH, prevalent data-driven techniques include support vector regression (SVR) and Gaussian process regression (GPR), alongside hybrid models merging machine learning with conventional estimation techniques to heighten predictive accuracy. RUL prediction sees advancements through deep learning techniques, especially LSTM and gated recurrent units (GRUs), improved using algorithms such as Harris Hawks Optimization (HHO) and Adaptive Levy Flight (ALF). This study underscores the critical role of integrating advanced filtering techniques, machine learning, and optimization algorithms in developing battery management systems (BMSs) that enhance battery reliability, extend lifespan, and optimize energy management for EVs. Moreover, innovations like hybrid models and synthetic data generation using generative adversarial networks (GANs) further augment the robustness and precision of battery management strategies. This review lays out a thorough framework for future exploration and development in the optimization of EV batteries.

Published: January 2025

The growing complexity of real-world problems has heightened the need for critical thinking skills in education, particularly in fields like statistical education. This study examines the integration of the Flipped Classroom (FC) model with Problem-Based Learning (PBL) to foster critical thinking among university students. Conducted at Bhineka University, the research involved 60 students divided into experimental (FC+PBL) and control (PBL-only) groups. A mixed-methods approach was employed, combining pre-tests, post-tests, classroom observations, and reflective journals to collect quantitative and qualitative data. The experimental group participated in pre-class activities such as video lectures and quizzes, with in-class sessions focusing on collaborative problem-solving guided by PBL principles. Analysis of Variance (ANOVA) revealed a significant improvement in critical thinking skills in the FC+PBL group compared to the PBL-only group (p < 0.001). Qualitative findings highlighted increased engagement, collaboration, and deeper inquiry among the experimental group. These results underscore the potential of integrating FC and PBL to create dynamic, student-centered learning environments that enhance critical thinking and prepare students to tackle complex challenges effectively

Published: January 2025

Premarital sexual behavior has become a significant social issue among adolescents in Indonesia, particularly concerning the high rates of child marriage and unintended pregnancies. Despite efforts to promote Marriage Maturity to reduce these rates, its effectiveness requires further investigation, especially in the context of adolescent motivation to avoid risky sexual behavior. This study aims to explore adolescent motivation to avoid premarital sexual behavior by applying the Protection Motivation Theory (PMT), which involves threat appraisal and coping appraisal in adolescent decision-making to delay early marriage. This research employs a qualitative method with a phenomenological approach. Informant consisted of adolescents aged 15-19 years in Samarinda City who had received information about marriage maturity. Data was collected through in-depth interviews with six purposively selected Informant using intensity sampling techniques. Data validity was ensured through source triangulation and documentation. Collected data were analyzed using QSR NVIVO 12 Pro. The findings reveal that adolescents’ understanding of marriage maturityis still limited, and the threat of premarital sexual behavior is perceived as low by most Informant. Factors such as perceptions of severity adolescents are quite good because they have seen firsthand the impacts of premarital sex. For response efficacy and self-efficacy in delaying the age of marriage, these are relatively high among adolescents exposed to PUP. This is because they have parental and peer support providing information related to PUP. Additionally, social environment, media exposure, and education levels shape adolescents' responses to marriage maturityas a protective measure.
Le clocher-porche de Saint-Martial : un écho ou un prélude à l’entreprise du chevet ?

Den Vorhallenturm der romanischen Abteikirche Sankt Martial haben weder programmierte Grabungen noch archäologische Sondierungen auffinden können. Die alte Ikonographie kann also nicht neu interpretiert werden. Gleichwohl bietet das Kolloquium Gelegenheit, die wichtigsten Fragen erneut zu stellen, insbesondere weil wir gesicherte neue Kenntnisse über die große Baustelle des beginnenden 11. Jhs. und die Baustrategie besitzen. Haben Umgangschor und westlicher Glockenturm die karolingische Kirche an ihren Extremitäten erweitert, wie dies schon oft der Fall war ? Es muss darauf hingewiesen werden, dass Umgangschor und Kapellenkranz im Limousin zu dieser Zeit nicht ungebräuchlich waren, genauso wenig Torhallentürme, wovon die frühe Baustelle von Évaux (Departement Creuse) zeugt.

Published: January 2025

Ein genauer Grundrissvergleich zwischen Sainte-Foy von Conques und Saint-Sernin von Toulouse macht deutlich, dass der Architekt des zweiten Baus den ersten zum Vorbild genommen hat. Die beiden Grundrisse sind deckungsgleich, indessen aber nur teilweise : der Architekt hat gewisse Elemente (Joche, Pfeiler, Chorhaupt usw.) sowie ein Schema des Gesamtaufbaus vermessen. Diese Feststellung regt dazu an zu prüfen, ob es denn nicht möglich wäre, Verbindungskriterien gleicher Art zwischen beiden Kirchen zu identifizieren und darüber hinaus, zwischen – einerseits – den frühesten Bauten mit Umgang und Kapellenkranz wie zum Beispiel Saint-Martin von Tours oder Sankt Martial von Limoges, und, andererseits, den Nachfolgebauten, von denen in erster Linie die Jakobskirche von Compostella zu nennen wäre. Die erste, ausschließlich auf Grundrissen gegründete Analyse des vorliegenden Beitrags zeigt die Existenz von konstanten Merkmalen, die es näher zu untersuchen gilt, denn sie können uns Aufschluss geben über die Vorgehensweise der Architekten der Romanik.
Notes sur le massif occidental de Saint-Denis
Authors: Moulin Jacques
Published: January 2025

Le massif occidental de l’abbatiale Saint-Denis est un ouvrage suffisamment important dans les débuts de l’architecture et de la sculpture gothiques pour qu’il fasse l’objet d’une remise en question permanente des idées reçues. Grâce aux travaux effectués de 2012 à 2017, la façade et son décor sculpté ont pu bénéficier d’un examen rapproché. Cette observation a permis de tenter une critique d’authenticité des parements et de retrouver plusieurs dispositions qui avaient été oubliées, mais voulues par l’abbé Suger. Après une présentation de ces découvertes, qui concernent autant le bâtiment lui-même que les inscriptions qui l’accompagnaient, les ventaux des portes et les nombreux spolia que Suger mit en avant pour accompagner et justifier son œuvre, le massif occidental de l’abbatiale a été examiné dans son développement historique complexe, depuis l’achèvement du chantier à la fin du

XIIe siècle jusqu’aux travaux de restauration les plus récents. La démarche a été poursuivie à l’intérieur même du bâtiment et a conduit à une interprétation nouvelle du chantier. Ainsi, la première construction de Suger à Saint-Denis n’apparaît plus comme une avant-nef autonome, comme il a longtemps été affirmé, mais comme un projet avorté de reconstruction complète de l’église, et en particulier de sa nef carolingienne. En dépit des précautions prises par l’abbé, le projet en cours de réalisation fut remis en question par la communauté, et il dut être modifié. Ses deux premières travées furent alors transformées en une sorte d’avant-nef, qui ne prit sa forme actuelle qu’au début du XIXe siècle. Parmi d’autres précisions, il semble nécessaire de faire remonter vers 1128-1130 la date du démarrage du chantier. De même, il convient d’apprécier d’un œil nouveau les travaux effectués par l’architecte François Debret au début du XIXe siècle, car ils établirent les premières méthodes de restauration raisonnée des Monuments historiques et furent beaucoup plus respectueux que ceux commandés par les moines quelques décennies auparavant. Enfin, la redécouverte des pierres et relevés détaillés de l’ancien clocher nord remet au jour une des architectures les plus ambitieuses de la fin du XIIe siècle, où l’emploi savant du métal relayait une technique de taille de pierre ayant atteint un niveau de performance jusqu’alors insoupçonné.
THE CREATIVE WORK OF VOLODYMYR IVASYUK IN THE CONTEXT OF THE NATIONAL-PATRIOTIC CRISIS OF THE LATE SOCIALISM PERIOD
Authors:   Kyiv National University of Culture and Arts, Ilienko O.
Published: January 2025

This article is dedicated to a thorough analysis of Volodymyr Ivasyuk's creative work in the context of the national-patriotic crisis that took place in Ukraine during the late socialism period. Amidst the totalitarian regime, a fierce struggle for the preservation of national identity and cultural autonomy unfolded. The author explores how Ivasyuk's musical legacy, particularly his songs, functioned as a powerful emotional and symbolic resource for the formation of national consciousness, which became the basis for cultural resistance to the regime. Ivasyuk's creativity, in the context of strict political control, emerged as a factor that not only reflected the socio-cultural reality but also became an important element of resistance against the Soviet authorities’ aspirations toward national assimilation and cultural unification. Volodymyr Ivasyuk's songs, which gained wide recognition under Soviet rule, simultaneously served as a form of protest against ideological monopoly and cultural hegemony, contributing to the development of national self-awareness and identity. Studying this creativity allows for viewing the national pathos embedded in the music as a significant element of cultural resistance, capable of transforming societal moods and influencing changes in national policy. The article also examines the socio-cultural context of the Soviet era, particularly the mechanisms of ideological pressure and cultural censorship that limited the opportunities for freely expressing national sentiments. Ivasyuk, by disregarding censorship restrictions, successfully combined folk motifs with elements of contemporary pop music, creating a body of works that infused new meaning into national ideas and played a significant role in national revival during the national crisis. Thus, the article highlights Volodymyr Ivasyuk's role not only as a distinguished artist but also as an influential figure who significantly contributed to the formation of a new national consciousness. His work proved to be a crucial factor in the processes of national revival and the acquisition of independence, which gained particular relevance in the late 1980s and early 1990s.
Keywords: Ivasyuk, songwriting, national idea, patriotic crisis, late socialism, cultural autonomy.

O artigo aborda o papel da Polícia Militar no enfrentamento ao feminicídio, destacando as responsabilidades institucionais à luz do novo Art. 121-A do Código Penal Brasileiro. Essa legislação, sancionada em 2024, classifica o feminicídio como crime autônomo, aumentando penas e incluindo agravantes específicas, como violência doméstica, gravidez e vulnerabilidade da vítima. A pesquisa explora as dimensões de prevenção, repressão e proteção, enfatizando a necessidade de treinamento contínuo dos policiais e a implementação de protocolos padronizados, como o POP 100.9, que orienta a atuação em casos de violência de gênero. Além de destacar os avanços legislativos, o estudo reconhece desafios estruturais. Conclui que o enfrentamento eficaz ao feminicídio exige um esforço conjunto entre instituições públicas e a sociedade, com foco em fortalecer a proteção às vítimas e garantir respostas rigorosas e articuladas contra a violência de gênero.

The article explores how to build and perfect a short agricultural supply chain model in Vietnam as well as the behavior of buyers via social networks regarding the short supply chain model. Data was collected from a survey of 100 samples including farmer households and 402 samples from consumers. The article uses the Structural Equation Model to analyze sthe impact of factors on product consumption behavior in the short supply chain of agricultural products. Research shows that interest in consuming local food is growing. In this model, consumer behavior plays an important role in the success of the short-term supply chain model. When purchasing through this model, consumers can be assured of the quality and freshness of the product. Therefore, businesses and farmers need to pay more attention to developing this model in the future. The government needs to develop information technology and transportation infrastructure to promote this model.
O ENSINO DE MATEMÁTICA NO HORIZONTE DA EDUCAÇÃO INTEGRAL: REFLEXÕES SOBRE OS PLANOS DE ESTUDO TUTORADOS DE MINAS GERAIS

Durante o período da pandemia, o governo de Minas Gerais utilizou os Planos de Estudos Tutorados (PET) para continuidade das aulas nas escolas. Assim, a fim de compreender esse período, o objetivo deste artigo é investigar concepções sobre o Ensino de Matemática na perspectiva da Educação Integral e(m) tempo integral no PET. Para tanto, foi realizada uma investigação qualitativa, na qual nos valemos de duas técnicas principais: análise documental e entrevista semiestruturada. Os procedimentos metodológicos foram: análise de 16 PET destinados às escolas de tempo regular e três às de tempo integral; entrevista com dois professores de Matemática. Acrescenta-se que o estudo se ancorou em autores(as) do Ensino de Matemática e da Educação Integral. Como resultados, notamos que os PET evidenciam características da tendência tecnicista e da tendência formalista clássica, predominando uma visão de Ensino de Matemática focada em aquisição de habilidades. Nota-se ainda um foco no desenvolvimento individual favorecedor da reprodução de desigualdades. Ademais, o documento não só apresenta falta de padrão sobre a quantidade - e ausência de fundamentação para justificar o desenvolvimento das habilidades recomendadas - como também não específica as diferenças pretendidas na abordagem de Matemática em escolas de tempo integral e nas de tempo regular.

O QUE SABEM LICENCIANDOS E PROFESSORES BRASILEIROS SOBRE O CONCEITO DE VOLUME?
Authors: DE SOUZA MARIA ALICE VEIGA FERREIRA DE SOUZA , MENDUNI-BORTOLOTI ROBERTA
Published: January 2025

Pesquisas revelam que alunos não compreendem o conteúdo de volume e que o ensino vem tendo ênfase na conversão de unidades e fórmulas matemáticas. Pesquisadores relatam que o ensino da grandeza volume deva ser estudado pela distinção e articulação em relação aos domínios geométrico e de número, em três diferentes dimensões: comparação, medição e produção, nessa ordem. Desejamos conhecer a amplitude e profundidade do conceito de volume de nove professores e 61 licenciandos em Matemática de duas diferentes regiões geográficas brasileiras, à luz da literatura da comunidade de investigadores da Educação Matemática. Os professores participantes foram submetidos a problemas com situações de volume nas três dimensões indicadas e a uma entrevista semiestruturada. A pesquisa empírica revelou que os participantes demonstraram conhecimento sobre comparação e medição de volumes, com e sem uso de fórmulas, apesar de frequentemente subsidiarem, equivocadamente, suas decisões no domínio geométrico e de apoiarem seus raciocínios, prioritariamente em cálculos com números. Na dimensão de produção, revelaram desconhecimento sobre relações entre massa, densidade e volume, além de não distinguirem os significados de volume e capacidade.

Authors: Mesquita Élis Gardel , Carvalho Fernando , Costa Eudes
Published: January 2025

Neste trabalho, estamos interessados em estudar funções lineares e quadráticas envolvendo a função piso, as quais denominamos funções piso de graus 1 e 2, respectivamente. Mais especificamente, determinamos o conjunto de seus zeros, além de estabelecer condições necessárias e suficientes sobre os coeficientes para que tais zeros existam. É apresentado um método que nos permite encontrar e detalhar os conjuntos solução, descrevendo-os como união finita de subintervalos da reta.

Published: January 2025

O presente artigo é o recorte de um estudo de mestrado que teve três etapas metodológicas. Entretanto, neste texto apresentaremos apenas a primeira etapa, a qual teve como objetivo analisar possíveis temáticas de Educação Financeira Escolar (EFE) em Histórias em Quadrinhos (HQs) que abordam a temática Educação Financeira (EF). Para atender a este objetivo, analisamos narrativas de HQs com potencialidade para o trabalho com distintas temáticas de EF. Buscamos as HQs em repositórios digitais, analisamos e selecionamos quatro que têm problematizações referentes à EF. Para analisar as HQs, embasamo-nos nas temáticas de EFE elaboradas por Santos (2017). Os principais resultados apontaram a possibilidade do trabalho com mais de uma temática de EF em uma mesma narrativa, o que evidencia a pluralidade e a riqueza de discussões de EF com o uso de HQs. Concluímos que as HQs analisadas podem potencializar discussões de questões que geram uma amplitude de possibilidades do trabalho significativo e de caráter transversal da EF.

TERNAS PITAGÓRICAS E SEQUÊNCIAS NUMÉRICAS: NOVOS RESULTADOS
Authors: Tanaka Thiago Yukio , Peixoto Campos Gésica , Gonçalves de Castro Airton Temistocles
Published: January 2025

A partir de uma abordagem interdisciplinar, apresentamos respostas dentro da classe de problemas das Ternas Pitagóricas para três casos. Mais precisamente, provamos casos de existência e inexistência de Ternas Pitagóricas de termos envolvendo as Progressões Aritméticas, as Progressões Geométricas e a Sequência de Fibonacci. Mostramos que, no caso das Progressões Aritméticas, as únicas Ternas Pitagóricas são geradas por uma famosa tripla. No caso das PGs e da Sequência de Fibonacci, provamos a inexistência de Ternas Pitagóricas de inteiros positivos, mesmo quando os termos não são consecutivos. Até onde vai o nosso conhecimento, as respostas para os problemas aqui estabelecidos no caso das PGs e da Sequência de Fibonacci são inéditas. O trabalho é consequência dos estudos de uma dissertação de mestrado profissional (PROFMAT-UFRPE), na qual apresentamos alguns resultados clássicos sobre sequências numéricas e suas aplicações.
