This study aimed to analyze the learning experience and retention of physical science students with multimedia resources. This quantitative research utilized a descriptive-correlation design to assess the data collected from 133 senior high school students of Valencia City, Bukidnon, and preferences, and technical aspects of the learning experiences have an overall score integration in physical science class. It also revealed that the students’ retention improved relationship between learning experience and retention in physical science classes aided with retention of physical science concepts for students. This leads to a deeper understanding of complex physical science concepts and improved knowledge retention compared to textbased methods. As research continues to explore the optimal design and implementation of multimedia in physical science education, it holds great promise for fostering a more engaging and effective learning environment for students....
Multimedia technology, widely applied in the internet+ education model of today, has been extensively used in primary education. This paper analyzes the advantages of multimedia technology in primary school mathematics education, specifically discussing its role in stimulating students' interest in learning, enriching teaching methods, and optimizing the allocation of teaching resources. By using multimedia forms, students can understand abstract mathematical concepts more intuitively and vividly, thereby improving learning efficiency and interest. This paper summarizes a series of strategies for the application of multimedia, particularly pointing out that the reasonable use of multimedia in concept teaching and problem-solving method transmission not only enhances the interactivity of classroom teaching but also strengthens students' independent learning ability and thinking ability. This paper points out that through reasonable design and effective use of multimedia teaching, a pleasant learning atmosphere can be created for students, thereby promoting the mastery of knowledge. At the same time, teachers' teaching efficiency and classroom management ability have also been significantly improved. This study provides theoretical support for how to effectively apply multimedia technology in primary school mathematics teaching and offers valuable practical references for improving the quality of primary school mathematics teaching....
Current studies have paid extensive attention to the occurrence of brominated flame retardants (BFRs) in aquatic environments; however, there is a lack of exploration of BFRs in ice media in freshwater environments, and there are fewer studies on the distribution patterns and ecological risks of BFRs in different media. In order to fill this gap in the current research status, this study conducted four seasonal samplings in the Songhua River wetland in Northeast China. The distribution and risk of 14 polybrominated diphenyl ethers (PBDEs) and 22 new brominated flame retardants (NBFRs) in water, ice, sediment, and soil were analyzed using liquid–liquid extraction sample pretreatment and gas chromatography–mass spectrometry instrumentation. A total of 18, 5, 8, 19, and 18 BFRs were detected in non-icecovered water, ice-covered water, ice, sediment, and soil, respectively. NBFRs dominated contaminant concentrations in each medium. Significant correlations were found between BFRs in ice and subglacial water, suggesting that the sources of BFRs in these two media are similar and there is an exchange between them. The ice enrichment factor (IEF) revealed the water–ice distribution mechanism of BFRs, indicating that wetland ice acts as a temporary sink for 2-(Allyloxy)-1,3,5-tribromobenzene (ATE), 1,2-Dibromo-4-(1,2-dibromoethyl)cyclohexane (α-TBECH), 1,2,5,6-Tetrabromocyclooctane (TBCO), and 2-Bromoallyl 2,4,6-tribromophenyl ether (BATE). In order to achieve dynamic equilibrium, the exchange profile of BFRs between water and sediment requires the release of BFRs into water. The risk quotient (RQ) indicated that TBCO in water and ice poses a moderate risk to aquatic organisms, and its potential impact on wetland ecology cannot be ignored....
The ability to automate and personalize the recommendation of multimedia contents to consumers has been gaining significant attention recently. The burgeoning demand for digitization and automation of formerly analog communication processes has caught the attention of researchers and professionals alike. In light of the recent interest and anticipated transition to fully autonomous vehicles, this study proposes a text–image embedding method recommender system for the optimization of personalized multimedia content for in-vehicle infotainment. This study leverages existing pre-trained text embedding models and pre-trained image feature extraction methods. Previous research to date has focused mainly on textual-only or image-only analyses. By employing similarity measurements, this study demonstrates how recommendation of the most relevant multimedia content to consumers is enhanced through text–image embedding....
Face animation aims to render the source image according to the motion of the driving images while preserving the identity information of the source image. Despite significant advancements with the introduction of additional information, the literature lacks a thorough exploration of identity preservation. This paper proposes a Prior Structure- Assisted Identity-Preserving (PSAIP) network for face animation. Specifically, we introduce the additional priors of portrait segmentation images and face landmarks, which provide rich face geometric information while masking background interference to generate more realistic face images. Furthermore, we design an identity-enhancing generator network to adaptively fuses the identity feature information extracted from the source portrait and motion representations. Also, we utilize an identity-aware feature loss based on segmentation to avoid background distractions and monitor the identity preservation ability of the model. Extensive experiments on the VoxCeleb dataset and HDTF dataset show that our method is superior in identity preservation and realistic visual effects....
