Abstract

General Background: Islamic Religious Education requires learning approaches that support not only cognitive attainment but also the affective domain and character formation. Specific Background: At SMP Muhammadiyah 56 Binjai, Grade VII Islamic Religious Education learning was still largely teacher centered, theoretical, and minimally dialogic, so students had limited opportunities to reflect on and internalize Islamic values in daily life. Knowledge Gap: Existing learning practices had not optimally facilitated value clarification, moral reflection, and conscious decision making, while students’ Islamic character awareness remained low. Aims: This study aimed to develop a multimedia based Value Clarification Technique model for Islamic Religious Education and examine its feasibility, practicality, and outcomes in fostering students’ Islamic character awareness. Results: Using Research and Development with the ADDIE model, the study involved 18 Grade VII students, an Islamic Religious Education teacher, and school stakeholders. The developed product obtained very high material validity (98%) and design validity (97%), while practicality reached an average of 95.2%. Learning outcomes also improved, with the mean score increasing from 54 on the pretest to 80 on the posttest, an N-Gain of 0.534 in the moderate category, and mastery rising from 11% to 83%. Novelty: The study offers an integrative Value Clarification Technique model supported by interactive video and reflective value discussion specifically designed for Islamic Religious Education. Implications: This model provides a structured and contextual alternative for strengthening Islamic character awareness and the affective dimension of learning in junior secondary Islamic Religious Education. Highlights• Developed a multimedia-supported Value Clarification Technique model through the ADDIE stages for Grade VII Islamic Religious Education.• Achieved very high feasibility and usability, with 98% material validity, 97% design validity, and 95.2% practicality.• Recorded learning progress from a mean pretest score of 54 to 80, with N-Gain 0.534 and mastery rising from 11% to 83%.

Abstract

General Background: Trace elements are essential micronutrients that regulate enzymatic activity, cellular metabolism, and redox balance in biological systems. Specific Background: Among these elements, zinc, copper, and iron participate in processes closely associated with tumor development, including oxidative stress regulation, DNA repair, angiogenesis, and cell proliferation. Knowledge Gap: Although numerous studies describe the biological roles of individual trace elements, limited research has examined their combined molecular interactions and integrated contribution to cancer progression. Aims: This review analyzes the roles of zinc, copper, and iron in carcinogenesis by examining their involvement in oxidative stress generation, genomic instability, angiogenic signaling, and cellular growth mechanisms, while also discussing potential diagnostic and therapeutic applications related to trace-element modulation. Results: Evidence indicates that zinc supports antioxidant defense and DNA repair mechanisms, while dysregulated copper promotes angiogenesis and tumor cell migration. Iron participates in redox reactions that generate reactive oxygen species capable of inducing oxidative DNA damage and genomic instability. Alterations in the concentration and bioavailability of these elements are associated with tumor development and progression across multiple cancer types. Novelty: This study presents an integrated perspective on the collective biochemical roles of zinc, copper, and iron in carcinogenesis, emphasizing their interconnected molecular mechanisms rather than isolated biological functions. Implications: Understanding the coordinated behavior of these trace elements provides new directions for biomarker development, early detection strategies, and therapeutic approaches based on regulating metal homeostasis in cancer biology. Highlights: Metal Imbalance Contributes to Oxidative Stress, Genomic Instability, and Abnormal Cellular Proliferation in Tumor Development. Angiogenic Signaling and Tumor Migration Are Associated With Elevated Copper Concentrations in Malignant Tissues. Redox Reactions Involving Iron Generate Reactive Oxygen Species That Damage Genetic Material and Promote Genomic Instability. Keywords: Trace Elements, Zinc, Copper, Iron, Carcinogenesis

Abstract

General Background: Glass fiber reinforced polymer composites based on polyester matrices are widely applied in engineering due to favorable strength-to-weight ratio, corrosion resistance, and economic viability. Specific Background: Despite these advantages, their tensile and flexural performance is often limited by weak fiber–matrix interfacial bonding and matrix brittleness. Recent studies have reported that nano-silica incorporation may modify matrix behavior and improve stress transfer mechanisms. Knowledge Gap: However, a structured conceptual integration linking nano-silica content, dispersion quality, and interfacial bonding efficiency in polyester-based GFRP systems remains insufficiently synthesized in the literature. Aims: This critical review proposes an analytical framework to explain the interrelationship between nano-silica loading, particle dispersion, and mechanical response in polyester GFRP composites. Results: Literature findings consistently indicate that low to moderate nano-silica contents (0.5–1.0 wt%) with uniform dispersion contribute to improved tensile and flexural behavior, reduced micro-void formation, and enhanced load transfer, whereas excessive loading leads to particle agglomeration, stress concentration, and mechanical degradation. Novelty: The study integrates dispersed experimental evidence into a unified conceptual model without introducing new experimental data. Implications: The proposed framework offers theoretical guidance for optimizing nano-silica modified GFRP systems while maintaining cost feasibility and conventional fabrication compatibility. Keywords: Nano-Silica, Polyester GFRP, Filler Dispersion, Interfacial Bonding, Mechanical Properties Key Findings Highlights 1. Optimal nanoparticle loading occurs within a narrow low-percentage range. 2. Particle clustering correlates with premature cracking mechanisms. 3. Microstructural uniformity governs stress transfer efficiency.
