IMPACT OF PROJECT COST CONTROL ON THE FINANCIAL PERFORMANCE OF SELECTED CONSTRUCTION FIRMS IN NORTH-CENTRAL NIGERIA
Authors: Joseph Alu Abani , Ogedengbe Dr. Frank Alaba
Published: October 2024

Effective financial performance is crucial for the growth of construction companies, and project cost control plays a key role in achieving this, using financial measures such as Return on Assets (ROA), Return on Equity (ROE), Cost Variance Analysis (CVA), and Earned Value Analysis (EVA). This study examined the impact of project cost control on the financial performance of selected construction firms in North-Central Nigeria. Data were collected from 102 construction professionals using a structured questionnaire, achieving a 100% response rate. Descriptive statistics (mean, frequency, percentage) and multiple linear regression were employed for analysis. The results showed that CVA and EVA significantly influence financial performance, with R-squared values of 69% for ROA and 77% for ROE. The regression models indicate that ROA = -0.012 + 0.605(CVA) + 0.746(EVA), and ROE = 2.359 + 0.087(CVA) - 0.143(EVA). The study concludes that CVA positively predicts both ROA and ROE, while EVA positively but negatively predicts ROE. It is recommended that construction firms enhance their use of project cost control techniques to minimise cost overruns, delays, and quality issues, leading to improved financial performance.

Published: October 2024

This comprehensive study examines the durability of concrete exposed to aggressive environments, a critical issue for the longevity of modern infrastructure. Our research analyzes the influence of concrete composition parameters and environmental conditions on its long-term durability. A series of rigorous experiments were conducted to evaluate the effects of various chemical attacks on the mechanical and physico-chemical properties of concrete, focusing on particularly aggressive environments such as seawater, acidic solutions, and wastewater. We studied two types of concrete: ordinary concrete and concrete with additives, to compare their performance in these hostile environments. The results show significant variations in the properties of concrete depending on environmental conditions and composition parameters. Compressive strength, water absorption, and microstructure were systematically analyzed at different time intervals, revealing distinct degradation trends for each type of concrete and environment. The collected data highlights the critical importance of concrete formulation in resisting chemical attacks. Concrete with additives demonstrated superior performance in most aggressive environments, underscoring the essential role of additives in enhancing durability. The study also identified key degradation mechanisms, including leaching, carbonation, and sulfate attack, providing valuable insights for the development of more resilient concrete. This research makes a significant contribution to the understanding of the complex interactions between concrete composition and aggressive environments. The results have important implications for the design and maintenance of concrete structures exposed to severe environmental conditions, paving the way for strategies to improve the long-term durability of infrastructure.

Published: October 2024

Composite materials are of great importance in many industries due to their unique properties, strength and durability, but they also include disadvantages that can affect their use and must be studied. In this article, we simulate the acoustic interference field received by a delay line following an interaction between an acoustic field and a multilayer carbon fibre composite material using the ray approach. In this case, the simulation is performed using carbon fiber composite plates, where some plates have lamination defects such as delamination, while others are free of these defects. Experimental measurements are performed on carbon fiber composite plates with and without delamination defects introduced beforehand, without knowing their thickness. The thickness of each ply is 0.125 mm. The transducer used is a focusing immersion transducer type parametric (V 312) that operates at a frequency of 10 MHz The simulation results almost exactly corroborate those of the experiment. The simulation model was employed to determine the thickness of the induced delamination, which is 0.2 mm, found in the second and third layers.
Faedo-Galerkin method for the time-fractional reaction-diffusion model
Authors: Faizi Rima , Atmania Rahima
Published: October 2024

This paper investigates a time-fractional reaction-diffusion equation characterized by a Caputo derivative of  fractional order ,   incorporates non-local and memory effects that are essential for accurately modeling complex diffusion processes in such environments. These effects arise from the fractal nature of the media, which leads to anomalous diffusion behavior that cannot be adequately described by classical diffusion models. We start by giving a definition of a weak solution for this problem,  ensuring that the solution satisfies the equation in a generalized sense.  Subsequently, the Faedo-Galerkin method combined with compactness arguments is employed to establish the existence and uniqueness of the weak solution. This approach involves approximating the solution using a sequence of finite-dimensional functions and then passing to the limit to obtain the desired solution . Moreover,  we establish the stability of these solutions, which is fundamental for understanding their behavior under varying conditions and ensuring the reliability of the model . Our findings contribute to a deeper understanding of anomalous diffusion phenomena in fractal media and provide a solid foundation for further research in this area.

Published: October 2024

This study presents a comprehensive investigation into the mechanical behavior of sandwich composite structures featuring six distinct core geometries under three-point bending conditions. Through detailed finite element analysis (FEA), the research examines the performance characteristics of I-shaped, traditional honeycomb (NIDA), O-shaped, X-shaped, semi-circular, and modified core geometries. The analysis focused on stress distribution patterns, displacement responses, and overall structural integrity. Results demonstrate that the semi-circular core geometry exhibits superior mechanical properties, achieving an 84.66% improvement in positive stress resistance and 74.79% enhancement in negative stress resistance compared to the traditional honeycomb reference model. The study revealed consistent linear elastic behavior across all models within the tested displacement range, with the semi-circular configuration showing optimal stress distribution and minimal core deformation. Using aluminum for facings and core materials, the research evaluated mechanical responses through displacement-controlled loading conditions, measuring stress concentrations at critical points and analyzing deformation patterns. This research provides valuable insights into the relationship between core geometry and mechanical performance, offering practical implications for engineering applications requiring high strength-to-weight ratios and enhanced flexural resistance in modern structural design.

Published: October 2024

The paper goal is to investigate the significance, logic, and effects of momentum in tennis matches in order to offer logical advice to athletes and tennis coaches. the paper created a quantitative momentum model and mostly finished three tasks based on the research objectives. Firstly, the paper develop a momentum quantification model and set four essential indicators to quantify the momentum. By adding together these indicators, the paper may determine a player's momentum score at a given scoring point. And a shift curve of momentum scores is shown using the momentum scores acquired at each scoring point, providing the groundwork for determining the competition's turning point in the future. Secondly, the randomness of momentum is assessed by us. To evaluate coaches' skepticism about the impact of momentum, the paper conducted two randomized experiments to investigate this issue. The first test is a randomness test based on outcome correlation. The paper calculate the correlation between the winner and the player with the highest score on the final score. The second test is the permutation test, which involves generating a large number of random permutations by redistributing the labels of the data points. It then calculates the consistent distribution between the highest momentum scorer and the competition winner under these random permutations. The test results all indicate that the player with the highest momentum score is the winner of the game. The paper proves that momentum plays a crucial role in the matches, and predicting momentum can be utilized to anticipate pivotal moments in the game.

Beyond Benchmarking: A Diagnostic Inquiry into the Underlying Determinants of Low Performance in Philippine PISA Science
Authors: Cabural Adones
Published: October 2024

The Philippines’ consistently low performance in the Program for International Student Assessment (PISA) Science Assessment has sparked concerns about the country’s educational quality and competitiveness. The science scores are due to socioeconomic status, teacher quality, resource deficiencies, and systemic issues. A multi-pronged approach with evidence-based interventions is recommended to improve scientific literacy. This paper conducts a diagnostic inquiry into the underlying determinants contributing to Filipino students’ underachievement in PISA science. Drawing from an extensive literature review, the analysis identifies several interrelated factors spanning multiple levels of the educational system. Socioeconomic status, motivation, self-efficacy beliefs, and language proficiency emerged as significant predictors at the student level. School-level determinants include resource deficiencies, lack of qualified science teachers, and inadequate instructional practices. Furthermore, systemic issues like fragmented policy implementation, curriculum misalignment, and insufficient investment in education undermine performance. The paper argues for a holistic, multi-pronged approach targeting these diverse determinants through evidence-based interventions and policy reforms to enhance scientific literacy and elevate educational outcomes in the Philippines.

Published: October 2024

Este estudo tem como objetivo a compreensão da relação entre a gastrite atrófica autoimune (GAMA) e a tireoidite autoimune, destacando a interconexão entre essas condições e suas implicações para a saúde dos pacientes. A GAMA é uma condição crônica que pode comprometer o fundo e o corpo do estômago, resultando em atrofia e substituição do tecido gástrico por uma mucosa similar à intestinal. Por outro lado, a tireoidite autoimune, frequentemente associada ao hipotireoidismo, é marcada pela inflamação da glândula tireóide e pelo aumento dos anticorpos contra a peroxidase tireoidiana. A revisão da literatura revelou que GAMA e tireoidite autoimune frequentemente coexistem, indicando uma relação significativa entre essas doenças autoimunes. A elevada prevalência de outras doenças autoimunes em pacientes com GAMA, com a tireoidite autoimune sendo uma das mais comuns, reforça essa conexão. Biomarcadores como gastrina e cromogranina A têm se mostrado valiosos para a detecção precoce e acompanhamento de condições associadas, como a hiperplasia de células semelhantes à enterocromafina (ECL). Compreender essas associações é essencial para desenvolver estratégias de tratamento mais eficazes e adaptadas às necessidades individuais dos pacientes. Integrar essas informações no manejo clínico pode melhorar a qualidade de vida dos pacientes e ajudar a prevenir o surgimento de outras doenças autoimunes. No entanto, são necessárias pesquisas adicionais para aprofundar o conhecimento sobre a interação entre GAMA e tireoidite autoimune e aprimorar as abordagens terapêuticas. A identificação precoce e o monitoramento contínuo são fundamentais para otimizar o tratamento e oferecer cuidados mais precisos e personalizados.

Authors: Thu Trang Nguyen Thi , Thu Hang Do , Thu Huong Tran Thi , Diem Huong Nguyen Thi
Published: October 2024

Interest rate risk is potentially averse to a commercial bank's trading book and banking book. The sharp and rapid volatility of interest rates can push commercial banks to fall into difficult situations, thus leading to instability of the whole banking system. Therefore, interest rate risk in banking book (IRRBB) management plays a vital role in banking operations. This paper analyzes the current management of IRRBB at 21 commercial banks in Vietnam by doing in-depth interviews and questionnaires. The finding indicates that the level of IRRBB management of commercial banks in Vietnam is mostly relatively completed or inadequate, with the highest levels belonging to international commercial banks and the banks that implement Basel II. Furthermore, the study also executes a simulation of IRRBB management at one commercial bank according to current regulations of the State Bank of Vietnam. Based on the selected interest rate scenarios, the capital requirement for IRRBB is calculated, which is the actual simulation for commercial banking in implementing the IRRBBB framework.  Finally, to improve the effectiveness of IRRBB management in Vietnam, some implications for the State Bank of Vietnam and commercial banks are provided.

Published: October 2024

In 2023, the average age of Korean women for the first marriage and giving birth was reported to 31.45 and 33.6, respectively. Due to the late marriage, the number of patients undergoing infertility treatment per 100,000 in Korea increased by 16.9% over the past five years to 27.3. Recently, interest in social oocyte cryopreservation (SOC) has been growing in Korea as a strategy to address the low birth rate. This study is descriptive research to determine the influence of unmarried women's knowledge of fertility preservation, tendency toward late marriage, and awareness of fertility preservation on intention to SOC. This study aims to identify predictors of unmarried women's intention to SOC. Data were collected from July 20 to 26, 2024, through a online self-reported survey from unmarried women in their 20s to 40s. 234 copies were collected, but 211 copies were used for the analysis after excluding 23 insincere responses. The data were analyzed using descriptive statistical analysis and logistic regression analysis using the SPSS/PC 29.0 program. In this study, 41.7% of unmarried women intended to SOC, while 58.3% did not. In addition, the intention to SOC was higher when they wanted children (p=.041, exp(B)=2.35), were aware of SOC (p=.015, exp(B)=2.98), and had a high awareness of fertility preservation (p<0.001, exp(B)=1.47). But the higher the tendency to marry late (p=.044, exp(B)=.92), the lower the intention to SOC. The findings can serve as foundational data to increase social awareness of SOC for unmarried women and to help develop supportive policies.

This case report aims to examine the diagnostic and therapeutic approach for phenytoin-induced Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome in a pediatric patient, emphasizing the importance of early recognition and intervention. A 17-year-old male presented with a pruritic rash, fever, lymphadenopathy, and elevated liver enzymes one month after starting phenytoin for epilepsy. Diagnosis was confirmed using the RegiSCAR scoring system, which objectively assessed clinical and laboratory findings. The patient received high-dose corticosteroids and N-acetylcysteine (NAC) after discontinuing phenytoin, with regular monitoring of clinical and laboratory parameters. Timely withdrawal of phenytoin, along with corticosteroid and NAC therapy, led to the resolution of symptoms without long-term complications. The RegiSCAR scoring system proved invaluable for accurate and swift diagnosis, supporting its utility in pediatric DRESS cases. This case also suggests the potential of genetic screening, particularly HLA typing, for identifying high-risk individuals, although it was not utilized here. Early diagnosis and multidisciplinary management are critical for favorable outcomes in pediatric DRESS cases. Routine HLA screening could help prevent DRESS syndrome in patients prescribed high-risk medications, though further studies are needed to assess feasibility and cost-effectiveness. This case underlines the value of standardized treatment protocols and personalized medicine in managing drug hypersensitivity reactions effectively.

Published: October 2024

Japanese is one of the foreign languages taught in formal and informal educational institutions in Indonesia. The development of Japanese language learners is increasing quantitatively. In foreign language courses, native and non-native teachers collaborate on pedagogical tasks. This trend is also happening in Japanese foreign language courses. In addition, there are around 6,617 non-native Japanese language teachers (Japan Foundation, 2021). There is an argument that Native Japanese Speaker Teacher's (NJST) has many advantages over Native Japanese Speaker Teacher's (NNJSTs) and that students prefer NNJSTs over NJST, but the argument must be assessed. Many researchers have explored students' perceptions of NJSTs and NNJSTs worldwide in formal education institutions but not in the non-formal education institution sector. This study aims to explore the perception of Indonesian students towards NNJSTs in non-formal educational institutions, namely LPK Fuji Academy Singaraja with all samples coming from active students registered from January to August 2024. This study is a quantitative research with a descriptive approach conducted using an instrument in the form of a closed questionnaire based on the Likert scale. This study revealed that the perception of male and female students did not have a significant difference in their teaching competence based on the theory of Nuibe et al (2006). Male participants rated NNJSTs higher in terms of teaching effectiveness and communication skills, with an average score of 9.8. In contrast, female respondents gave slightly lower ratings in these areas with an average of 7.1. Furthermore, through this research, students need NNJSTs more because they allow for a successful learning process because of effective learning strategies. In addition, NNJSTs also help students in facing difficulties and challenges in their learning process.
