Authors: Noguera María Clara , Orozco Shelly , Lizarazo Diana , Escandón Patricia 
Published: December 2024

Introducción: Candida auris es una levadura emergente, multirresistente relacionada con infecciones invasivas en centros de atención en salud. El objetivo de este estudio fue describir la prevalencia de C. auris en Colombia (2018-2021). Materiales y Métodos: Se recopilaron datos de aislamientos clínicos sospechosos de C. auris de pacientes con infección fúngica invasiva, y su confirmación fue posible mediante MALDI TOF MS o PCR. Se estudió la susceptibilidad antifúngica siguiendo parámetros del CLSI y se determinó la sensibilidad a anfotericina B, fluconazol, voriconazol y anidulafungina. Resultados: De 1143 aislamientos sospechosos de C. auris, recibidos principalmente de la Región Caribe y Región Andina, un 56% (640) se confirmaron como C. auris mientras que en 44% (503) se identificaron otras levaduras; hubo mayor frecuencia de casos entre 19 y 60 años; se identificaron 189 casos de infección por SARS CoV 2 y C. auris en los dos últimos años. La susceptibilidad antifúngica de 820 aislamientos mostró resistencia a alguno de éstos en 760, así como la presencia de resistencia simultánea a dos clases de antifúngicos en 150. Discusión: Se observó aumento de la participación de las entidades territoriales, sugiriendo mayor sensibilización de los profesionales para sospechar de este patógeno y reportarlo. A pesar de la resistencia observada a ciertos antifúngicos, los aislamientos no mostraron una multirresistencia preocupante, lo que permite pensar que aún existen opciones terapéuticas para el control de las infecciones causadas por esta levadura en el país.

Published: December 2024

Objective: Synthesize and characterize the heterogeneous catalyst MoO₃/Ce-SBA-15, to be applied in the transesterification reaction of soybean oil.

Theoretical Framework: The molecular sieve SBA-15 is a mesoporous silica used as a support for the dispersion of active metals. Modification with cerium (Ce) enhances the textural properties, while doping with molybdenum oxide (MoO₃) increases the catalytic activity. This catalyst is applied in transesterification for the production of biodiesel, a renewable and efficient biofuel to replace fossil diesel.

Method: Ammonium cerium nitrate was introduced along with the silica source in the synthesis gel, evaluating different Si/Ce molar ratios (10, 20). The obtained material was doped with MoO3 using the pore saturation method and evaluated in the transesterification reaction at different temperatures.

Results and Discussion: Characterization analyses indicated that the longer crystallization time (48h) and the introduction of Ce into the structure improved the crystalline and textural properties of SBA-15. The presence of MoO₃ in its orthorhombic phase was confirmed by X-ray diffraction analysis. The maximum yield of methyl esters was 86.56% at 150°C using the 15MoO3/10Ce-SBA-15 catalyst.

Research Implications: This research developed a new catalyst efficient in biodiesel production, contributing to the field of catalysis. Promoting advances in renewable energy and sustainability.

Originality/Value: This study reports the influence of Ce as a structural promoter in the synthesis of a new catalyst (MoO3/Ce-SBA-15) to be applied in the transesterification reaction for biodiesel production.

Authors: Oliveira Kenia Cristina de , Cruvinel Vanessa Resende Nogueira , Sousa Antônio Ralph Medeiros , Obara Marcos Takashi 
Published: December 2024

Objective: To describe and analyze the diversity of mosquitoes in urban areas of the Federal District (DF), Brazil, the types of breeding sites, and the relationships between climatic variables and the abundance of the main vector species.

Theoretical Framework: The potential distribution, endemicity, emergence, and re-emergence of pathogens transmitted by mosquitoes is regulated by fluctuations in potential vector Culicidae communities. Studies on the diversity of culicids are important to understand the ecological relationships between species and the environment they occupy. However, information on diversity patterns and the structure of the culicid fauna in the DF is still scarce and dispersed in the literature.

Method: Mosquito larvae collected and identified in urban areas of the DF between January 2014 and December 2018 were evaluated for abundance, constancy, dispersal capacity, similarity of specific composition among Administrative Regions, and abundance by type of breeding site. The influence of macroclimatic factors was verified using the Spearman coefficient.

Results and Discussion: The results revealed 12 species of mosquitoes, with higher abundance, constancy, and dispersion among Aedes aegypti and Culex quinquefasciatus. Precipitation and relative humidity were the abiotic factors that most influenced total abundance, with similar results recorded in other studies.

Research Implications: Understanding the structure of the Culicidae fauna, and in particular, the identification of local parameters that shape these communities are important for adequate approaches to control vector species.

Originality/Value: Shows the benefits that disease-vectoring mosquito species find in the Federal District.

Energy prices and the stock market are two of the crucial factors in the evolving landscape of global finance, particularly in major emerging economies. However, research on how energy price changes impact stock markets in BRIC countries remains limited, despite their diverse roles in global energy markets and economies. This study investigates the causal dynamics between energy prices and stock market performance in BRIC countries, aiming to uncover short-term fluctuations and long-run relationships in these major emerging economies. Utilizing daily data from 2013 to 2023, stationarity tests, cointegration analysis, and Granger causality tests are employed to examine these relationships. Key findings reveal weak evidence of a long-run equilibrium between energy prices and stock market indices, challenging previous assumptions about their cointegration. More significantly, the findings uncovered a strong unidirectional Granger causality from oil prices to all BRIC stock market indices, while gas prices show a more selective influence. Notably, no evidence of reverse causality from stock markets to energy prices was found, highlighting the exogenous nature of global energy prices in relation to BRIC stock markets. This study uniquely analyzes oil and gas price effects on BRIC stock markets, offering insights for investors and policymakers amid increasing commodity-financial market integration.

Transformational Leadership and Project Success: The Role of Leader-Member Exchange and Professional Commitment
Authors: Thuy Doan Thi Thanh 
Published: December 2024

The purpose of this study is to explore the effects of transformational leadership (TL) on project success (PS), focusing on the indirect impacts of leader-member exchange (LMX) and the moderating influence of professional commitment (PC). This study aims to address the inconsistent findings in existing literature regarding the transformational leadership-project success relationship and to uncover the mechanisms that affect project outcomes. The unit of analysis is finished projects. The 509 project managers on projects completed within the past five years responded to the poll to collect data. The data were then assessed using Smart-PLS software. The results confirmed the study’s hypotheses, demonstrating that LMX mediates the relationship between transformational leadership and project success. Additionally, professional commitment was found to moderate both the relationship between transformational leadership and LMX and the connection between LMX and project success. Furthermore, transformational leadership was shown to have a direct positive effect on project success. These findings contribute to the theoretical foundations of leadership and project management by emphasizing the critical role of relationship quality within teams, with LMX serving as an intervention mechanism and professional commitment acting as a moderating role influencing project success. The insights from this study offer practical value for developing project management strategies tailored to specific organizational contexts, enhancing efficiency in project-based organizations. Future research should consider longitudinal studies to explore how the relationships between these antecedents and project outcomes evolve over time. Doi: 10.28991/ESJ-2024-08-06-022 Full Text: PDF

Financial Development Strategies of Countries: Identifying Priority Financial Instruments
Authors: Gospodarchuk Galina , Zeleneva Elena 
Published: December 2024

The effectiveness of financial development strategies for countries depends on the methodology used for their formation and implementation. However, a review of the literature reveals that the methodology for implementing these strategies is not fully developed. Therefore, this study aimed to create a methodology for implementing financial development strategies by identifying priority financial instruments. The study utilized rule-based judgment, iterative methods, and the "GAP" method. As a result, the "5S+" concept was developed—an expanded version of the "5S" concept. The novelty of the "5S+" concept lies in its inclusion of financial instruments, as well as the rules and methods for determining priority financial instruments. This is the first time such a modification of the "5S" concept is proposed. The "5S+" concept was tested using data from the UK for 2007-2022. The test results allowed us to determine the UK's strategic financial development goals for 2023-2025 and identify priority financial instruments necessary to achieve these goals across the board. The expanded "5S" concept is highly representative, objective, and broadly applicable. It enhances the existing methodology for strategic financial development management and introduces new opportunities for improving the quality of strategic policy documents.

Published: December 2024

Affordable IoT PM2.5 sensors, enabled by the Internet of Things, offer new ways to monitor air quality. However, concerns exist about their data accuracy. This study aimed (1) to investigate the low-cost PM sensor's performance under various outdoor ambient circumstances and (2) to evaluate seven calibration methods, which include decision trees, gradient-boosted trees, linear regression, nearest neighbors, neural networks, random forests, and the Gaussian Process. The Davis AirLink was used as a reference to compare the Plantower PMS3003 sensor's performance. The data from the Plantower PMS3003 sensor were then compared to the Davis AirLink values using calibration curves created by machine learning algorithms. Calibration curves were generated using machine learning algorithms trained on sensor measurements collected in two Thai cities (Nakhon Si Thammarat and Phuket). Our results show that all machine learning methods outperformed traditional linear regression, with decision trees and neural networks demonstrating the most significant improvement. This research highlights the need for sensor calibration and the limitations of current calibration methods and paves the way for advancements in cloud-based calibration and machine learning for improved data accuracy in IoT PM2.5sensor technology.
