Essential oils hold tremendous medicinal attributes and are greatly exploited industrially worldwide. Lindera is an important genus of the Lauraceae family of plants which are known for their medicinal values. In the present study, eleven studies reported on Lindera essential oils were selected and reviewed. Then the variability of essential oil components in the genus Lindera were assessed by multivariate analysis. The chemical analysis enabled the identification of qualitative and quantitative differences among the essential oils. The essential oils were characterized by high proportions of germacrene B, spathulenol, nerolidol, β-caryophyllene, dihydromyrcene, furanosesquiterpenoid, sesquithuriferol, and linalool. Then, the differences in the chemical profiles of the essential oil were confirmed by the multivariate statistical analysis, which was determined via principal component analysis (PCA) and hierarchical clustering analysis (HCA). The analysis classified the Lindera species .....

This study explores the application of virtual reality technology and traditional offline hybrid teaching mode for the specialized course “Animation Laws of Motion”. Through the improved ORB algorithm, this paper effectively combines the BRIEF and ORB image feature and matching algorithms to optimize capturing and matching image features. Two classes of animation majors in a school were selected for experiments in the study, and the effects of the two teaching modes were compared through half-term tests, pre- and post-test question analyses, and questionnaire surveys. The results show that after the teaching assisted by VR animation technology, students' acceptance and emotional attitudes are significantly improved, and the students in the experimental class better mastered the six motion methods in the animation motion course and completed the animation design tasks with high quality. In the animation modeling course, the proportion of low-quality works in the experimental class i.....

The metaverse is an envisioned realm offering immersive digital spaces, bolstering highly interactive environments within educational contexts. This digital dimension amplifies synchronous communication, uniting a vast number of users as they share their unique experiences. This research aims to scrutinize the perceptions of elementary students towards the metaverse system (MS). Our proposed model underwent validation through the Partial Least Squares Structural Equation Modelling (PLS-SEM) technique. Data, sourced from 287 students of Dubai National School, revealed that the primary predictor of students' intent to engage with the MS is personal innovativeness. This is followed closely by perceived usefulness and then perceived ease of use. The findings of this research provide deeper insights into the driving factors behind the adoption of MS among young learners. © 2024, Semarak Ilmu Publishing. All rights reserved...

This research aimed to determine the ideal racquet size by modifying racquets based on a body-scaling approach employing arm-to-racquet length ratios. Twelve boys aged between 13 to 14 years (13.17±0.83) with one to two years of badminton experience volunteered to participate in the study. To calculate arm-to-racquet length ratios, participants' arm lengths for both hands were recorded. Participants were divided into six pairs and played a badminton match using three types of racquets which were racquets A (1.1:1.0), B (1.0:1.0), and C (0.9:1.0). Participants' hitting opportunities, successful strokes, winning strokes, rally length, and unforced errors were notated manually via video replay. Based on the one-way ANOVA with repeated measures, the results showed that the use of racquet B which had a pi ratio of 1.0:1.0 for arm length-to-racquet length ratios during badminton matches, recorded the highest mean scores in hitting opportunities, successful strokes, and winning strokes than .....
