Authors: Abellana El Chamberlain , Abellana Losel Mae
Published: February 2025

The study explored the dominant learning styles, influential factors, and preferred learning activities and media of Grade 7 students enrolled in the Korean language program, aiming to enhance instructional material design and teaching strategies. Adopting a one-group descriptive research design, the study involved a total population of 80 students. A purposive sampling procedure was used in selecting the respondents. The study covered the scope within the second semester of the school year 2021-2022. Data collection employed two main instruments: Fleming’s VARK model, which identifies learning styles (Visual, Auditory, Read/Write, and Kinesthetic), and a 20-item questionnaire adapted from Ancho (2019) to identify learning preferences. Results were analyzed using frequency, percentage, and mean. The findings reveal that the majority of respondents were visual learners, favoring activities that included reading and writing dialogues as well as the use of comic strips. These preferences suggest that visually engaging and text-rich materials are particularly effective in facilitating language acquisition. Additionally, factors such as cultural interest and relevance of Korean pop culture emerged as significant motivators for learning the language. The study underscores the importance of tailoring instructional materials to align with students’ dominant learning styles and preferences. By incorporating visually stimulating and interactive media, educators can enhance engagement and improve learning outcomes. These insights provide valuable input for curriculum development, particularly in designing activity sheets and pedagogical approaches that resonate with learners’ needs and interests.

Authors: Chasokela Doris
Published: February 2025

Technology use is crucial and fundamentally alters how universities teach and learn in the twenty-first century. The influx of various technologies supports the development of three key 21st-century skills: life and career skills, learning and innovation skills, and information, media, and technology skills. Social constructivism theory serves as the study’s theoretical foundation, emphasizing the importance of collaborative learning environments where students construct knowledge through social interaction. A case study design and a qualitative methodology were employed in the investigation to gain deep insights into the experiences of participants. Those involved in the study included STEM lecturers, faculty technicians, and both first- and final-year undergraduate students; they were chosen using a purposeful sampling procedure to ensure a rich variety of perspectives. Data were collected through in-depth interviews, which provided valuable qualitative insights. The paper explores the 21st-century skills essential for STEM learning, focusing on the implications, competencies, and perceptions of various stakeholders. The study established a pressing need for training in technology integration among faculty. Additionally, there was minimal support from administration and technicians, as well as a lack of adequate resources. Participants expressed the need for ample time to prepare for lessons, highlighting the challenges educators face. Consequently, it is recommended that the implementation of technologies should begin with strong support from administrators and technicians in sourcing necessary resources. Lecturers play a crucial role in preparing students for the modern workplace, and they require continuous training and support from technicians. Furthermore, administrators should foster collaboration with other STEM-offering universities to stay current with rapidly evolving technologies, ensuring a comprehensive approach to education in the digital age. This collaboration can significantly enhance the educational quality and effectiveness of STEM programs.

Published: February 2025

Site investigation contribute to the total cost of building projects. Notwithstanding, the cost of site investigation in Nigeria is often skipped, which have detrimental impacts on the total cost of building projects. Therefore, this study aimed to identify the factors that influence site investigation costs and their impact on the total cost of building projects in Abuja, Nigeria. A sample of 50 construction sites within F.C.T, Abuja were chosen. Data analysis include Mean Importance Rating (MIR) for classifying the variables, and correlation analysis to examine which impact of site investigation contributed to the total cost of building projects. MIR findings indicated that unforeseen site condition, site geology, investigation depth and extent, project size and complexity, and environmental conditions should be considered during site investigation planning to minimize cost variability. Furthermore, direct correlation with cost savings, and effective risk management show strong positive correlations (>0.8), indicating a significant association with cost-saving benefits. This upholds that thorough site investigation can mitigate risks by providing valuable data on subsurface conditions, environmental factors, and other site-specific characteristics. It was thus recommended that construction professionals should conduct thorough feasibility studies and assessments, and adopt innovative and advanced site investigation technologies such as geophysical surveys, ground-penetrating radar, and 3D mapping to gain more accurate insights into the site’s conditions.

Published: February 2025

Rapid industrialization and population explosion has led to increasing need for building construction projects to either provide shelter or for business ventures in urbanizing areas. A survey research design which made use of questionnaire to elicit relevant information from the respondents comprise the people (residents and shop owners) domiciled where building construction projects are executed located in three (3) urbanising LGAs in Ibadan metropolis namely, Egbeda, Lagelu and Akinyele. A sample size of 384 was arrived at using surveymonkey sample size calculation for unknown population. The study revealed harmful effect of building constructions projects as “ecological impact” with grand Relative Impact Index (RII) value of 0.96(1st) posed to have most harmful effect from activities of construction firms in the study area. This is followed by that “pollution impact” having a grand RII of 0.94(2nd) and then “energy impact” with grand RII value of 0.92(3rd). The third objective on evaluation of steps taken by construction firms in abating the harmful effects of their construction activities in the study area reveals that the respondent are highly dissatisfied with mitigation measures put in place by the construction firms with mean item scores ranging from 1.27 to 2.48. The study’s hypothesis was retained, thus upholds that Environmental Impact Assessment (EIA) mitigations measure put in place by constructions firms do not have significant effect implementation of building construction projects as P-value of 0.396 at 95% significant level. The stud established that building construction projects have over time had major environmental impact in the study area causing significant destruction to the ecosystem, natural resources depletion and compromised public health hygiene. The study therefore recommends that huge fine and sanctions should be imposed on EIA report defaulters and ministry of environment should devise mechanism to ensure strict site monitoring to ensure enforcement of EIA report.

Published: February 2025

Despite the increasing militancy pressures and agitations, the oil and gas firms operating in Nigeria have remained adamant to the discharge of their corporate social responsibility, on the inimical pretence that it constitutes a drain on their financial position. This study investigate the relationship between corporate social responsibility cost and financial performance of quoted oil and gas companies in Nigeria from 2018-2023. Community development cost, and employee benefits cost were the proxies corporate social responsibility while net profit margin and return on investment were the proxies of financial performance. The researchers adopted expost- facto research design for the study. The study used secondary data obtained from the audited annual reports and accounts of the nine quoted oil and gas firms’ website and the Nigeria stock exchange fact book as at November 8, 2024. The research data was analyzed using basic descriptive, Pearson product moment correlation and multiple regression in a cross sectional data with the aid of SPSS version 27. The findings revealed that all the CSR proxies significantly related with net profit margin and return on investment of listed oil and gas firms in Nigeria in the period of this study. We thus concluded that corporate social responsibility has significant relationship with financial performance of quoted oil and gas firms in Nigeria in the period of this study. We recommended that Management of oil companies should develop a well-articulated corporate social responsibility and prioritize their spending regarding human resource development, community development, and environmental protection in order to guarantee a conflict free corporate atmosphere needed by managers and workers for maximum productivity and robust financial performance.

Published: February 2025

This study explored the determinants of Financial Reporting Quality (FRQ) in the Ministries, Departments, and Agencies (MDAs) of Gombe State, Nigeria. By examining key factors such as internal control systems, human resource quality, information technology utilization, and the adoption of International Public Sector Accounting Standards (IPSAS), the research identified the critical elements that influence the transparency and accountability of public financial reporting. Using data collected from senior accountants across Gombe State’s MDAs, the study found that robust internal control systems significantly enhance FRQ, while IPSAS adoption marginally influences reporting quality. However, human resource quality and IT utilization have limited effects on financial reporting outcomes. The findings offer valuable insights for policymakers, government agencies, and academics, providing actionable recommendations for improving public sector financial management practices. This research contributes to the theoretical understanding of FRQ and underscores the importance of strengthening governance mechanisms to reduce fraud, mismanagement, and inefficiency in public sector financial disclosures

Published: February 2025

The measurement of risks and returns are the variables for determining the performance of real estate investments. Risk is the probability of variation between actual and expected outcomes, while return is the profit realized from investment. Factors such as capital expenditure, operating expenditure, location, and scale are important variables in hotel investment. However, since this study concentrates on three-star hotels, scale was not considered as all hotels under consideration were of the same scale. This study analysed the risks and returns of investment in three-star hotels in Enugu city between 2015 and 2024 by calculating the Arithmetic Mean Return (AMR), Standard Deviation (SD), and Coefficient of Variation (COV) over the period. From a study population of fifty (50) three-star hotels in seven (7) locations in the city namely: Independence Layout, New Haven, Ogui Road, GRA, Trans Ekulu, Ebeano Tunnel, and Abakpa Nike, seven (7) hotels were selected,one from  each location for the study. Data on the net annual income and capital values of the hotels between 2015 and 2024 were obtained through questionnaires sent to the general manager of each of the selected hotels. The results of the study found an inverse relationship between risks and returns among hotels with high capital values; risks were high while returns were lower. Hotels located in the city centre also had less returns due to higher expenditure and competition associated with central location. The study recommends that hoteliers should increase their returns and reduce risks by reducing their capital and operating expenditure.

Authors: UMEOKA, N.  , OHALETE, C. N.  , OZUOMBA, J. O.  , ORIOHA, N.
Published: February 2025

The study investigated the antifungal activities and phytochemical composition of Solanum macrocarpon Lin. Leaf extract. The research was carried out at the Microbiology Laboratory, Department of Microbiology, Faculty of Biological Sciences, Imo State University, Owerri, Nigeria. The phytochemical revealed that alkaloid, phenol, saponin, flavonoid and tannin were present while steroid and terpenoid were absent. Quantitatively, flavonoid, constitutes the highest substance at 9.44% while phenol was lowest with 0.145. Antifungal investigation reveals that aqueous and ethanol extract of Solanum macrocarpon Lin was able to exhibit strong inhibitory activity against fungal isolates. (Aspergillus niger, Fusarium oxysporum, Geotrichum candidum and Botrodipodia theobromae tested). Ethanol extract showed higher inhibitory effect than aqueous extract. In aqueous extract the inhibitory effect is independent of the extract concentration. For 0.5ml aqueous, Fusarium oxysporum had 2.3cm mycelium growth while it was 2.93cm in 1ml. Botrodipodia theobromae had 3.95cm mycelium growth in 0.5ml but 2.75cm in 1ml. The ethanol extract inhibition increases with increase in concentration. In Geotrichum candidum at 0.5ml, mycelium growth was 1.60cm but 1.02cm in 1ml. The antifungal activity of these extract is possibly linked to the presence of flavonoids, saponins and tannins. Further analysis should be carried out to determine the precise active bioactive compounds from Solanum macrocarpon L. that could inhibit fungi growth.

Authors: Rocha Cibele Aparecida De Moraes , Sousa Gisele Monteiro de , Gomes Antonio Jorge de Lima
Published: February 2025

This work deals with the comparison of the compressive strength in 4 concrete mixes and rupture of 36 specimens in the city of Teófilo Otoni. The first concrete trace was of    the conventional type and the other three used colored additives in the percentages 3%, 5% and 6%. After curing, axial compression tests were performed on the tests at the ages of 7, 14 and 28 days. Through the disruptions, we can see that the concrete results that obtained results below expectations were samples with percentages of 5% and 6% pigments. Samples with 3% additive showed resistance close to theoretical values of 18, 25 and 40 MPa. The presence of biotite in the region's aggregates also may have contributed to the loss of strength of the concrete, due to its lamellar aspect, which demands more water and makes it difficult to incorporate the aggregates.
Evaluation of the life cycle and the use of recyclable materials in paving
Authors: Vieira Gledsa Alves , Kunert Rafael Ferreira
Published: February 2025

Paving Engineering can be responsible for a considerable part of the environmental impact on infrastructure and construction projects. As a result, sustainability once again becomes a key research theme. This article aims to raise sustainable aspects related to LCA (Life Cycle Assessment), and its use in paving with recycled materials. With the increasingly frequent use of recycled or even reused materials, it is necessary to establish methodologies to quantify the level of sustainability of a product/process. Thus, results can be obtained that go beyond the life of the pavement, allowing a better understanding of the negative impacts, such as the energy demand involved in the construction, operation, and maintenance of the track. In addition, through weightings about each impact (environmental, social, and economic) it is possible to have better decision-making, as well as better optimization of applicable resources. The LCA allows the determination of a sustainability factor, being able to consider parities in the weightings, that is, 33.33% for each assessed impact (social, environmental, and economic). Or allocate 50% for environmental impact and 25% for social and economic impacts. A consideration is possible in which 50% weighting is adopted for economic impact and 25% for social and environmental impacts. This factor allows for better decision making, allowing to assess the pillar of greatest interest.

Authors: Ephraim Sheraz  , Shafiq ur Rehman  , Tanvir Ahmad Raja  , Abair ul Haq  , Husnain Yousaf
Published: February 2025

Introduction: Contrast-induced nephropathy (CIN) is one of the most frequent renal complications for patients who have received primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI). CIN is associated with a longer length of hospitalization, increased in-hospital mortality and poor overall survival. It is for this reason that there is a need to establish predictors of its occurrence in order to reduce the frequency of its occurrence and improve patients’ outcomes. Objectives: The main aim of the present research was to identify factors that may cause CIN and to evaluate the immediate outcomes of this condition in patients who underwent PCI in a large Pakistani teaching hospital. Materials and Methods: The current prospective study involved 200 STEMI patients who were candidates for PPCI. Patients’ baseline demographic and clinical characteristics and their biochemical profiles were also obtained with CIN as an increase of ≥0.5 mg/dL or ≥25% increase in serum creatinine. Descriptive statistics showed the following individual variables as independent predictors of CIN. Results: CIN was present in 34% of patients. These baseline characteristics were identified as critical predictors for the development of AKI were age, diabetes, baseline renal dysfunction, and contrast volume. CIN was also linked with increased length of hospital stay and increased mortality rate in the hospital. Conclusion: Despite being a potentially preventable issue, CIN continues to be a concerning factor in patients with PPCI, and risk assessment, preventive measures and the appropriate procedural approach should be defined early.

Authors: Martínez Florentín Gema
Published: February 2025

Relevancia: Este artículo es el inicio de un estudio sobre cómo afecta a las habilidades visuales del deportista el uso del casco de protección compensado con gafa y como afecta compensado con lentes de contacto.Propósito: Mostrar casos reales de la aplicación de lentes de contacto en la práctica deportiva de Hockey y observar cómo puede afectar su uso a las habilidades visuales del deportista. Como objetivo secundario se muestra la respuesta de las habilidades visuales de los casos realizados con casco y sin casco de protección, con la refracción compensada en gafa y con lentes de contacto.Informe de casos: La muestra son tres niños, dos de sexo masculino y una femenino, con edades comprendidas entre los 13 y los 14 años, los cursos lectivos van de 1º de la E.S.O. a 3º de la E.S.O., están federados en Hockey y pertenecen todos al Club Rollybears, según el cuestionario realizado los tres deportistas tienen un nivel de actividad física alto, las agudezas visuales con compensación son de entre 1,0 y 1,5. Las pruebas de habilidades visuales se han realizado en la Clínica Optométrica de la Facultad de Óptica y Optometría de la Universidad Complutense de Madrid.Conclusiones: Se han mostrado 3 casos reales de adaptación de lentes de contacto en jóvenes en la práctica deportiva de Hockey con habilidades visuales en optometría. Se han mostrado las respuestas de las habilidades visuales de los casos realizados con casco y sin casco de protección, con la refracción compensada en gafa y con lentes de contacto sin muestra suficiente para comprobar diferencias en las condiciones analizadas. Debe realizarse más investigación en este campo con una muestra mayor de casos para obtener unos resultados que puedan analizarse estadísticamente y nos aporten información sobre el rendimiento de las habilidades visuales de los deportistas en condiciones limitantes.

Propósito: Conocer la asociación entre la percepción global del movimiento y la velocidad de lectura en niños sanos con edades comprendidas entre 7 y 9 años.Material y Métodos: Se incluyeron un total de 26 participantes, de los cuales el 57,7% eran mujeres. Se incluyeron sujetos con visión binocular normal y una agudeza visual decimal superior a 0,90 en visión próxima. Los participantes con diagnóstico de dislexia fueron descartados. El estudio se llevó a cabo por el mismo profesional, en el mismo colegio dónde se encontraban los pacientes, de forma individualizada y con una duración aproximada de 30 minutos por paciente.Resultados: Los resultados mostraron que la percepción global del movimiento estaba correlacionada con la velocidad de lectura, principalmente, cuando la sensibilidad del movimiento se medía con un número de puntos coherentes elevado (40%). No obstante, la velocidad lectora también estaba asociada con la discriminación visual deficiente y la eficiencia de los movimientos sacádicos necesarios para lectura. A suvez, a mayor coherencia de puntos, mayor correlación se encontraba con la discriminación visual y con la deficiencia de movimientos sacádicos.Conclusiones: Nuestros hallazgos apoyan la hipótesis de que la percepción global de movimiento, aunque en menor medida que la discriminación visual, está asociada a la velocidad lectora.

Relevancia: La finalidad de este trabajo es encontrar los tratamientos que mayores beneficios dan sobre el control de miopía para así en un futuro prevenir factores de riesgo, evitando futuras pérdidas severas en la visión y mejorando la calidad visual del paciente.Resumen: El objetivo de este trabajo es la elaboración de una revisión bibliográfica sobre los diferentes tipos de control de miopía que existen, con el fin de conocer el más empleado en la actualidad y el que mejor resultados ha dado hasta la fecha. Además, se hará un repaso tanto de los conceptos básicos de miopía, como los factores de riesgo que supone una progresión de la misma. Se realizó una búsqueda bibliográfica en la base de datos PubMed, libros optométricos, y la gaceta de optometría y oftálmica del colegio de Ópticos Optometristas de artículos a partir del año 2000 que han sido seleccionados a partir de unos criterios de inclusión y exclusión. Se encontraron un total de 4939 resultados para el objetivo principal del trabajo que fueron acotados mediante los criterios de inclusión y exclusión hasta obtener un total de 30 artículos divididos en los apartados de introducción y discusión del trabajo. Los tratamientos con mayor peso en la actualidad debido a sus resultados efectivos son la atropina y la ortoqueratología. Sin embargo, se encuentran nuevos avances como las lentes de contacto con desenfoque periférico que demuestran mejoras sobre los efectos secundarios de estas dos anteriores. Pese a los grandes avances y los nuevos tratamientos propuestos es necesaria mayor investigación acerca del control de miopía.

Relevancia: El objetivo principal del estudio es comparar la curva de la Sensibilidad al Contraste (SC) obtenida con tres dispositivos diferentes en pacientes sanos. Dos de los instrumentos empleados utilizan redes sinusoidales como estímulo, mientras que uno de ellos emplea como estímulo letras.Propósito: En el presente estudio se comparó la curva de SC obtenida con tres dispositivos diferentes, en pacientes sanos.Material y Métodos: La muestra consistió en 72 ojos emétropes o con defecto refractivo previamente corregido, de los cuales el 44,45% fueron hombres y el 55,55% fueron mujeres. La edad media de los sujetos fue de 24,67±2,58 años. Se replicaron las condiciones de medida para todos los sujetos.Resultados: Los resultados obtenidos indican la presencia de diferencias significativas en la medida de SC obtenida mediante el CC-100XP® respecto a las medidas obtenidas con el OptoMeP® y el Optotab®. No se encontraron diferencias significativas entre las medidas recogidas con el OptoMeP® con respecto al Optotab ®. Los tres instrumentos obtuvieron una buena repetibilidad.Conclusiones: Los tres test proporcionan medidas fiables y reproducibles de SC. Aquellos que emplean redes sinusoidales, dan valores mayores de SC que aquellos que emplean letras. El Topcon CC-100XP sobreestima los valores de SC respecto a los otros dos instrumentos.
