Abstract

This cross-sectional study looks at how junior high and elementary school students think about crisis energy. The tool is sent out through an open-ended online survey. There were 167 people who took part in the study. The number of sixth-grade elementary school students (14), seventh-grade students (51), eighth-grade students (6), and ninth-grade students (96) in Bandung City. The study's results showed that ninth-grade students came up with the most ideas, followed by eighth- and seventh-grade students. The ninth graders came up with the idea that "environmental crisis" was the most crucial concept; among eight pupils, "energy limitation" seemed to be the most critical concept; and among high school students, “energy" was the most crucial concept. These results suggest that higher levels of education can help people come up with bigger ideas about crisis energy. This is because they can learn through theory or practice. Ninth graders now know more about ideas related to the energy crisis. The research has implications for teachers because it lets them teach students more advanced ideas about crisis energy in addition to the basics

Abstract

Bone fractures are rising worldwide due to aging populations and increased trauma, creating demand for implants that overcome infection, delayed healing, and poor osteointegration. Multifunctional biomaterials, especially PLA–HA Bioxcrew systems, offer integrated mechanical support with antibacterial, anti-inflammatory, and osteogenic functions while remaining biocompatible. Implant-associated infections driven by Staphylococcus aureus and Gram-negative bacteria persist because of biofilm formation and chronic inflammation. Bioxcrew advancements address these barriers through metal-ion doping, nanoscale surface engineering, and incorporation of antimicrobial agents into biodegradable polymer matrices, enabling controlled ion release, immune modulation, stem-cell recruitment, and improved bone regeneration. Stainless steel provides strength, hydroxyapatite enhances biological integration, and PLA enables safe degradation and localized drug delivery, making their hybridization ideal for next-generation implants. Using a narrative–integrative review of peer-reviewed literature from 2018 to 2025, this study synthesizes trends in antibacterial strategies and regenerative performance. Findings show that hybrid Bioxcrew platforms significantly reduce infection risk and enhance functional bone healing.

Abstract

This study investigated the effectiveness of ThinkFeels Diary as a meta-affective and meta-cognitive assessment tool in supporting students' mental health in science classrooms. The study used a mixed-method approach and included 205 students.  The ThinkFeels Diary, which allowed students to record both cognitive learning components and affective responses (emotions and feelings) during science courses, was the main component of the intervention. The MENTAL-Q questionnaire was used in pre-test and post-test designs to quantify the influence on mental health. Qualitative data from 3,840 student reflections were analyzed using NVivo 12. Results showed varied outcomes across classrooms. Two topics demonstrated significant changes: "The Nature of Science & Scientific Method" (p = 0.037, mean difference = -0.16) and "Measurement" (p = 0.018, mean difference = -1.41), both showing decreased mental health scores, possibly due to increased metacognitive demands. Analysis of sub-dimensions revealed complex patterns: the "Human Digestive System" topic showed notable improvements in empathy (+0.39) and adaptability (+0.37), though accompanied by increased depression (+0.38) and stress (+0.26).  According to the qualitative analysis, students’ emotional awareness (meta-affective) interacts dynamically with strategic thinking (meta-cognitive) before, during and after the learning. Reflection acts as a crucial link that turns experience into growth. This findings revealed the need of considering cognitive-emotional demands of different science topics to effectively support student mental health.
