Abstract

3D printing technology has revolutionized the way products are manufactured, and it has opened up new possibilities in the field of smart materials. Smart materials are materials that can change their properties in response to external stimuli, such as temperature, pressure, or light. By combining 3D printing technology with smart materials, highly customizable and responsive products are created. The addition of the time dimension to 3D printing has introduced 4D printing technology, which has gained considerable attention in different fields such as medical, art, and engineering. To bridge the gap in knowledge of 4D, this paper assessed the revolution in healthcare with 3D/4D printing and smart materials. Data was generated as part of a broader empirical study which sought to explore healthcare personnel and electrical engineers’ perception on the practices around the use of 3D/4D printing technology and smart materials. The main method used was structured interviews. 12 participant were purposively selected and interviewed including healthcare personnel and electrical engineers form Philippines and Nigeria. The findings reveal an array of activities undertaken using both 3D and 4D. Furthermore, the study revealed that 4D printing is a new generation of 3D printing. Another aspect of the 3D usage is the integration of electrical stimulation and smart implant as a new area of study in healthcare. 3D could also be used to monitoring the smart implant performance. The study also evaluate the possibility of using Internet of things (IoT) in the smart implant as some device embeds smart materials. Smart implant commonly used includes orthopedic applications, such as knee and hip replacement, spine fusion, and fracture fixation. The smart materials used in this technology are important because 3D printing allows printed structures to be dynamic. The paper highpoints is that 4D printing has great potential for the future.

Abstract

The study aimed to investigate the impact of conflict resolution procedures on teachers' job satisfaction in Government Technical Colleges in Kano State, Nigeria. The population of the study was 367 respondents, including 15 principals and 352 technical teachers. A sample size of 201 respondents was determined using the correlational research design. The instrument used for data collection was a structured questionnaire titled "Principal’s Conflict Resolution Procedure Appraisal Questionnaire (PCRPAQ)." The questionnaire was validated by three experts, and the reliability index obtained using Cronbach Alpha was 0.82. The research questions were answered using the mean and standard deviation, and regression analysis was used to test the null hypotheses at a 0.05 level of significance. The findings of the study revealed that arbitration conflict management strategy and effective communication conflict management strategy had a moderate influence on teachers' job satisfaction. Based on the findings, the study recommends that civil societies should enlighten school administrators, teachers, and teachers' unions about the need to adopt the arbitration conflict management strategy, as the constitution provides for all labor-related cases to be handled at the arbitration court.

Abstract

This study examined the level of awareness, perception, and utilization of virtual laboratories in Nigerian Universities by Electrical Engineering lecturers. The study was guided by three specific objectives and three survey research types. One hundred twenty-one lecturers in electrical engineering from 8 universities in Nigeria's Northeast comprised the study's population. Because the total population size was manageable, the study used whole-population sampling. Data was collected using a validated questionnaire. A reliability index of 0.79 was determined using Cronbach Alpha. Mean, and standard deviation were used to answer the research questions. The findings revealed that all the electrical engineering lecturers in Nigerian Universities are highly aware of Virtual Laboratories, and all the electrical engineering lecturers in Nigerian Universities rarely utilized Virtual Laboratories. The study recommended that the National University Commission should use all of its resources to promote the development of electrical engineering practicum by providing virtual laboratories to all universities in Nigeria, as the study found that electrical engineering lecturers in Nigerian universities have a high level of awareness of virtual laboratories; in addition to supporting physical laboratories in the universities, the administration should provide for the training of laboratory technicians and electrical engineering lecturers in Nigerian universities on how to effectively use the virtual laboratory facilities for conducting various types of experiments.

Abstract

The COVID-19 pandemic has profoundly reshaped global education systems, not only disrupting learning processes but also intensifying long-standing concerns regarding student mental health and well-being. This article offers an opinion-based scholarly analysis supported by contemporary literature to critically examine the escalating mental health challenges faced by students in the post-pandemic era. Key issues include the surge in anxiety and depression, heightened academic pressure, digital overload, and the growing prevalence of bullying and cyberbullying. Drawing upon global evidence, this paper argues that educational systems have been insufficiently responsive to the psychosocial dimensions of learning, particularly in contexts where stigma and limited institutional support persist. Using a conceptual framework that integrates individual, pedagogical, digital, and systemic factors, this article synthesizes empirical findings and policy discourses to illuminate structural gaps in current educational practices. The results and discussion are organized into three thematic sub-sections addressing post-pandemic mental health trends, digitalization-related stressors, and systemic barriers to student well-being support. The paper concludes by advocating for a paradigm shift toward holistic, inclusive, and culturally responsive mental health strategies within education, emphasizing the urgency of embedding psychosocial well-being as a core educational priority rather than a peripheral concern.

Abstract

This study, titled Electric Motor Control: Innovations in Brushless DC Motors for Electric Vehicles, investigates advanced control technologies that enhance the performance, energy efficiency, and reliability of Brushless DC (BLDC) motors in electric vehicle (EV) applications. Employing a mixed-methods approach, the research integrates theoretical analysis, computational modeling, experimental validation, and real-world case studies. A comprehensive literature review from IEEE Xplore, ScienceDirect, SAE International, and industry reports forms the foundation, focusing on BLDC motor topologies, control strategies such as Field-Oriented Control (FOC) and Direct Torque Control (DTC), sensorless techniques, and emerging power electronics technologies including silicon carbide (SiC) and gallium nitride (GaN) devices. MATLAB/Simulink simulations are used to develop and test control algorithms, while electromagnetic and thermal analyses are conducted using ANSYS Maxwell and FLUX. Prototype validation involves hardware testing of a 1–10 kW BLDC motor system equipped with a DSP/FPGA controller and a SiC-based inverter under variable loads applied by a dynamometer. Key performance parameters, including torque ripple, energy efficiency, and thermal dissipation, are experimentally measured and statistically analyzed. The study also evaluates commercial EV systems, such as Tesla’s permanent magnet synchronous motors and Nissan Leaf’s BLDC implementations, to draw practical insights. Findings highlight that integrating advanced control methods, sensorless strategies, and high-performance power electronics significantly improves EV driving range, smoothness, and system durability. The results provide actionable insights for optimizing BLDC motor designs, addressing critical challenges in EV development, and supporting future innovations in sustainable transportation.

Abstract

Intelligent Tutoring Systems (ITS) have emerged as powerful AI-driven learning technologies capable of delivering personalized instruction at scale. This study provides a systematic review of literature published between 2020 and 2025 to examine the cognitive mechanisms through which ITS improve learning outcomes. A total of 20 empirical and high-impact studies were analyzed using predefined inclusion criteria focusing on adaptive feedback, knowledge tracing, scaffolding, metacognition, and motivational design. The findings reveal that ITS consistently produce small-to-moderate learning gains (d ≈ 0.30–0.70), with feedback and knowledge tracing identified as the most dominant and reliable mechanisms. Metacognitive supports demonstrate the strongest influence on deep learning and self-regulated learning, while scaffolding contributes to conceptual understanding and transfer. Motivation and engagement features, although less frequently studied, enhance persistence and learning intensity. The review also highlights emerging trends, including the integration of learning analytics, affective computing, and hybrid ITS architectures. However, challenges remain in model interpretability, standardization of outcomes, and alignment with pedagogical practices. This study contributes a synthesized framework linking cognitive mechanisms to learning effectiveness and provides directions for future research to develop more explainable, scalable, and pedagogically grounded ITS.
