Abstract

This study seeks to investigate the shape of the surface of tsunami waves using the finite difference method and the effect of the damping function on the simulation of tsunami wave propagation using Matlab-based visualisation. The effect of attenuation on the propagation of tsunami waves is measured by the variation in energy. The results of the investigation indicate that tsunami waves have a transverse wave form, with waves propagating in a perpendicular direction. In the meantime, the analysis of the damping function reveals a decrease in the value of energy; this indicates that if the damping function is provided, it will have the effect of reducing the wave energy and propagation speed of tsunami waves. This modelling clearly and realistically illustrates the results of wave movement visualisation and provides insight for disaster mitigation and coastal protection.

Abstract

This study aims to assess the perspectives of 200 respondents in Makurdi town, Benue State, Nigeria, on flooding using a Likert scale questionnaire. Flooding is a recurring challenge in the area, impacting lives and properties and necessitating effective flood management and mitigation strategies. The questionnaire covers various aspects of flooding, including frequency, property damage, flood warning systems, government efforts, climate change impact, community preparedness, and community-based initiatives. The findings reveal that flooding frequently occurs in Makurdi, emphasizing the urgency for comprehensive flood management strategies. Respondents acknowledge the personal impact of flooding, highlighting the need for effective mitigation measures. Improvement is needed in flood warning systems and government efforts to prevent flooding. Climate change's role in increasing flooding is recognized, emphasizing the importance of climate-resilient strategies. Community awareness and education are essential for reducing flood impacts, while public-private partnerships offer opportunities for collaborative flood management initiatives. The media's role in disseminating flood-related information is crucial. Stricter enforcement of building codes in flood-prone areas and community-based initiatives can contribute significantly to effective flood management. The implications of this study underscore the importance of community engagement, climate-resilient measures, and improved communication. Policymakers and local authorities can use these findings to develop targeted interventions for building a more flood-resilient Makurdi. By adopting proactive measures and community involvement, the town can enhance preparedness and adaptability to future flood scenarios, fostering a safer and more sustainable environment.

Abstract

Amid the COVID-19 pandemic, educational institutions in Indonesia, including vocational schools in Bontang, adopted remote learning policies to continue education. Surveys and interviews conducted with teachers at a vocational school revealed signs of stress, including quick temper, continuous mistakes in tasks, and forgetfulness. This study seeks to assess the level of mental workload, teacher performance, and the impact of mental workload factors on the performance of vocational teachers during the COVID-19 pandemic. Teacher performance is the dependent variable, while mental workload is the independent variable. Mental workload dimensions measured include time pressure, mental effort, and psychological stress, whereas teacher performance has work quality, accuracy/speed of work, initiative in work, workability, and communication. The study involved a sample of 20 teachers from a vocational school. Data analysis utilized simple linear regression processed using SPSS software. Subjective assessments of mental workload by teachers indicated that the highest proportion was the need for increased concentration during teaching activities. Regarding teacher performance, the highest ratios were associated with mastering teaching materials, managing the teaching-learning process, and leading the class during the COVID-19 pandemic. The simple linear regression testing results revealed a low influence of the existing mental workload on teachers' performance. The R square value indicated that mental workload affected teacher performance by 14.7%, with the rest influenced by variables outside the regression model.

Abstract

In parts produced by the P/M method, boriding is generally applied as a separate process after sintering. If the package boriding process is carried out during the sintering of the powder compact, sintering and boriding can be integrated; This not only prevents parts from deforming due to secondary heating, but can also reduce energy consumption. Carrying out sintering and boriding processes simultaneously is called Borosintering (B/S). Studies in the literature have stated that various material properties are improved thanks to the boride layers formed as a result of the borosintering process. It has been observed that the effect of different boronizing environments on the borosintering process has not been examined in any of the studies. In this study, media containing different weight ratios of silicon carbide (75%, 85%, 90%), boron carbide (5%, 10%, 20%) and the remainder one of various activators (Na2CO3, NaCl, Na2B4O7 (anhydrous borax) and NaF) in the boronizing medium were tested. Wear test (0.6 m/s sliding speed, 52 N load, 500 m distance, counter: 16MnCr5) was applied to some selected samples, the boride layer was examined by SEM, and elemental analysis was performed by EDX. Phases in the boride layer were detected by XRD. The hardness of the layer was measured with a microvickers test machine. The study showed that many different activators can be used in the borosintering process and that activators have a significant effect on the specifications of the boride layer. It was concluded that the NaF activator accelerates the formation of the boride layer more than other activators and creates a boride layer with better properties.

Abstract

This study addresses the persistent underrepresentation of female students in non-traditional vocational trades, specifically Motor Vehicle Mechanic Work, within Gombe State Technical Colleges. The total population for this study was 527 including administrators, teachers and parents of Motor Vehicle Mechanic Work trade students in Government Science and Technical Colleges in Gombe State. The sample size of the study was 116 determined using stratified random sampling. The study employed a descriptive survey research design, focusing on Gombe State in Nigeria, where seven Government Science and Technical Colleges were selected for the research. Three research questions and hypotheses guided the study. Data was collected through a researcher-developed structured questionnaire, and statistical methods including means, standard deviations, and ANOVA were used to analyze the data. Findings of the study indicated that parental influence, including preferences for preferred courses and concerns about safety, significantly influenced female students' enrollment in Motor Vehicle Mechanic Work. Peer group dynamics, such as imitation, aspirations, and subject choice, also played a role in shaping female students' decisions. Cultural factors, including perceptions of education, domestic roles, early marriage, and societal support, further influenced their choices. Interestingly, the study revealed a convergence of perspectives among Motor Vehicle Mechanic Works Trade teachers, school administrators, and parents regarding the identified influences. Recommendations stemming from these findings include targeted awareness campaigns for parents, peer mentorship programs, and collaborations with local leaders and institutions to challenge and reshape cultural norms that discourage female participation in non-traditional trades.
