Integrating multidimensional scaffolding into digital game-based learning is expected to address scientific inquiry teaching challenges, simulating real-world complexities to ignite learner interest. This study stands out by using realistic scenarios and multidimensional scaffolding to develop an online collaborative scientific inquiry game, designed based on the scientific inquiry process to create corresponding game mechanics and processes. It leverages cloud technology integration as scaffolding, accompanied by a train maintenance scenario with non-player characters (NPC) to enhance electromagnetism learning for learners. This study involved 90 college students divided into three groups: game scaffolding group (remote gaming teaching activities with NPC-based scaffolding), document scaffolding group (remote case study activities with document-based scaffolding), and no scaffolding group (remote case study activities without scaffolding). The results indicate that providing scaffolding in remote scientific inquiry teaching enhances learning outcomes compared to activities without scaffolding. Learners in the game scaffolding group reported a high level of flow experience, perceived that remote gaming teaching was helpful for scientific inquiry learning, and experienced lower anxiety. Furthermore, learners provided highly positive feedback on the usefulness of multidimensional scaffolding in the game. There were no significant differences among the three instructional activities in terms of flow state, activity anxiety, and the usefulness of scientific inquiry. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Method for providing exercise instruction that allows immediate feedback to trainees is proposed. The purpose of this research is to combine artificial intelligence technology and motion analysis methods to build an effective vocational training support program aimed at supporting the employment of children with disabilities. Specifically, we develop a system that uses DTW (Dynamic Time Warping) to calculate the similarity between the trainee’s motion and the model motion, and scores the results based on the results. This system will enable optimal instruction for each disabled child, and is expected to improve motion skills and promote learning motivation. Furthermore, by providing scored feedback, we aim to improve the traditional evaluation that relies on the subjectivity of the instructor and provide an intuitive and easy-to-understand means of confirming results for trainees. In this research, we use skeletal detection technology to record the trainee’s three-dimensional coordinate data and perform quantitative evaluation. In addition, we will design a program that allows trainees to visually check their own progress through a motion evaluation function and maximize the learning effect. Through experiment, it is found that the proposed method does work for motion trainings at supporting the employment of children with disabilities. Also, it is found that immediate feedback is better than conventional delayed feedback. © (2025), (science and Information Organization). All rights reserved.

Approach Detection and Warning Using BLE and Image Recognition at Construction Sites

引用

International Journal of Advanced Computer science and Applications 2025年第4期16卷 80-86页

Ensuring the safety of workers in dangerous areas is an important issue at construction sites. In particular, fatal accidents at construction sites often involve falls or traffic accidents, and tend to occur around hazardous areas. In this paper, to prevent such accidents, a proximity detection and warning system based on image recognition and Bluetooth Low Energy (BLE) technology is proposed. This system mainly uses image recognition to detect workers approaching dangerous areas, and uses BLE beacons as an auxiliary to achieve continuous detection even under occlusion conditions. A master-slave operation model is adopted, with image recognition serving as the main detection method and BLE beacons as an auxiliary. When a worker approaches a dangerous area, a real-time warning is issued via a wireless earphone connected to a smartphone, allowing immediate recognition and response. This has made it possible to reach the stage of detecting intrusion into dangerous areas. However, there are still some challenges remaining for this system. The first challenge is individual re-identification. In order to issue a warning to the relevant worker when an intrusion into a dangerous area is detected, the worker needs to be recognized individually. The second challenge is adapting to changes in the structure of the construction site. Since the environment of a construction site changes over time, it is necessary to consider the appropriate placement of cameras. Experiments show that the proposed method works well to locate workers approaching and entering dangerous areas. The proposed system also detects intrusion into dangerous areas through bone conduction wireless earphones from a distance of 115 meters and issues a warning to the corresponding workers. © (2025), (science and Information Organization).

Ductile Deformation Mechanism of Oriented Polystyrene Films

引用

Zairyo/Journal of the Society of Materials science, Japan 2025年第1期74卷 9-15页

作者： Nobukawa, Shogo Kitagawa, Yoshito Isobe, Hinata Inomata, Katsuhiro Graduate School of Engineering Nagoya Institute of Technology Gokiso-cho Nagoya466-8555 Japan Department of Life Science and Applied Chemistry Nagoya Institute of Technology Gokiso-cho Nagoya466-8555 Japan

Hot-drawing of polystyrene (PS) films improved the fracture nature from brittle to ductile due to the chain orientation. However, the brittle-to-ductile transition mechanism has not been clearly understood. This study investigated the ductile deformation mechanism of the oriented PS films by using birefringence and polarized FT-IR measurements during tensile tests. Comparison of tensile properties for the oriented PS films with various drawing conditions revealed that the brittle-to-ductile transition occurred at around 0.05 of the degree of chain orientation. The birefringence data, which were analyzed with a modified stress-optical rule (MSOR), suggested the chain orientation beyond the yield point during the ductile deformation. The polarized FT-IR data represented that, before yield point, the main chain of PS became oriented to the tensile direction, and, after the yield point, a phenyl ring as a side-group of PS aligned. The difference in the orientation behaviors of main-chain and side-group dissipated the stress concentration in the oriented PS films, and generated the shear-yielding deformation, resulting in the ductile deformation. © 2025 The Society of Materials science, Japan.

Decision-making is considered an essential competence of the twenty-first century skills. Remote synchronous collaborative problem-solving has gained much attention especially for decision-making training. We designed a framework to promote decision-making training with a multidimensional scaffolding-based game, and 84 participants were recruited online to evaluate the game based on the proposed framework. The quasi-experimental study compared collaborative and individual learners’ game performance, anxiety, motivation, acceptance, behavior patterns, and perceived learning process for decision-making. The result showed that both collaborative and individual learners had low anxiety, high motivation, and high acceptance in the multidimensional scaffolding-based online educational game;however, the collaborative team had better game performance and found the clues to be more useful for the learning process than the individual team did. Behavioral pattern analysis revealed that the high-performance collaborative team had more well-organized problem-solving and in-depth reflection. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

In this study, we prepared various aluminum-doped zinc oxide (AZO) surface structures via chemical bath deposition for use in biomedical sensors. Indium tin oxide (ITO) conductive films were deposited on glass substrates via electron beam evaporation, and AZO nanorods were subsequently grown on the ITO layer using chemical bath deposition at a bath temperature of 90°C. The AZO/ITO sensor electrode was further optimized through furnace annealing, improving its structural and electrical properties. This nanostructure enhances the ability of biomedical sensor films to adsorb H+ and OH- ions by increasing the reactive surface area between the film and the solution under test, thereby improving pH sensitivity. In addition, we used an extended gate field effect transistor module to measure glucose concentrations ranging from 0 to 10 mg/ml, achieving sensitivity values of 55.4 mV/pH and 8.07 mA/mg*ml-1. These findings have significant implications for the future development of blood glucose monitoring and microenvironmental sensing systems. © 2001-2012 IEEE.

NATURE REVIEWS METHODS PRIMERS 2025年第1期5卷 1页

An alkyne is an unsaturated hydrocarbon characterized by the presence of at least one C≡C bond. Alkyne groups generate a strong Raman peak in the cellular-silent region, a region between 1,800 and 2,800 cm−1where endogenous molecules do not produce a Raman signal. As a result, alkynes are regularly used as tags to label and visualize small molecules in live cells using Raman microscopy, a method referred to as alkyne-tag Raman imaging (ATRI). ATRI has been applied to various compounds to enable their cellular localization and, recently, alkyne-tagged compounds have been used as Raman sensors to detect intracellular biomolecules, such as metal ions or reactive oxygen species. ATRI has unique advantages over existing methods for localizing small molecules intracellularly, such as enabling super-multiplex detection and incurring a smaller impact on labelled compounds. In this Primer, we describe the principles and key techniques involved in ATRI, including the design of alkyne-tagged molecules, sample preparation and the set-up of Raman microscopes. We showcase the demonstration and application of ATRI, encompassing the development of responsive alkyne-tagged compounds for sensing biomolecules. Finally, we discuss the limitations and potential applications of ATRI, shedding light on the future possibilities of this method.

Improvement of Interference Fringes Analysis to Obtain Accurate Soret Coefficients

In this study, we proposed a moved-view analysis, a method for obtaining the Soret coefficient ST by analyzing the interference fringe change during field-of-view movement in the steady state. This analysis was designed to solve the problem that the sign of the concentration gradient could also be reversed if the plot of the concentration distribution was only slightly shifted owing to the narrow field of view. The data obtained from the experiment conducted to measure ST at the International Space Station were analyzed using moved-view analysis. For the moved-view analysis, the linearity of the concentration distribution induced by the Soret effect is larger than that for the method without field-of-view movement, and a more reliable ST can be obtained. The analysis error that sometimes occurred when the laser wavelength switched led to the underestimation of the phase change Δ, resulting in generating the data with low linearity. This unreliable data should be removed. © 2025 Trans Tech Publications Ltd, All Rights Reserved.
