Grounded in Social Impact Theory, this study examines the effects of virtual experiences generated by Mere Virtual Presence (MVP), Mere Virtual Presence with Product Experience (MVPE), and pure brand websites on consumers’ brand attitudes and purchase intentions. Additionally, it explores the moderating roles of Consumers’ Need for Uniqueness (CNFU) and product type (search vs. experience products). This study adopts an experimental design with three brand website types (MVP brand communities, MVPE brand communities, and pure brand websites) and two product types to examine the hypothesis. Specifically, a 3 (brand website type) × 2 (product type) experimental design was implemented to examine the influence of brand website types across different scenarios of online marketing. The findings reveal significant insights into consumer brand marketing. Specifically, consumers with low CNFU exhibited higher brand attitudes and purchase intentions compared to those with high CNFU when engaging with search products in MVPE brand communities Furthermore, fan avatars within a virtual brand community can still influence consumer perceptions even without direct interaction. These insights contribute to the growing body of research on personalized marketing and offer practical strategies for leveraging eWOM to enhance consumer engagement and influence decision-making in the digital landscape.

This study develops an immersive marine Information and Communication Technology (ICT) convergence framework designed to enhance coastal climate resilience by improving accessibility, visualization, and communication of scientific research on Dokdo (Dok Island) in the East Sea. High-resolution spatial datasets, multi-source marine observations, underwater imagery, and validated research outputs were integrated into an interactive virtual-reality (VR) and web-based three-dimensional (3D) platform that translates complex geophysical and ecological information into intuitive experiential formats. A geospatially accurate 3D virtual model of Dokdo was constructed from maritime and underwater spatial data and coupled with immersive VR scenarios depicting sea-level variability, coastal morphology, wave exposure, and ecological characteristics. To evaluate practical usability and pro environmental public engagement, a three-phase field survey (n = 174) and a System Usability Scale (SUS) assessment (n = 42) were conducted. The results indicate high satisfaction (88.5%), strong willingness to re-engage (97.1%), and excellent usability (mean SUS score = 80.18), demonstrating the effectiveness of immersive content for environmental education and science communication crucial for achieving Sustainable Development Goal 14 targets. The proposed platform supports stakeholder engagement, affective learning, early climate risk perception, conservation planning, and multidisciplinary science–policy dialogue. In addition, it establishes a foundation for a digital twin system capable of integrating real-time ecological sensor data for environmental monitoring and scenario-based simulation. Overall, this integrated ICT-driven framework provides a transferable model for visualizing marine research outputs, enhancing public understanding of coastal change, and supporting sustainable and adaptive decision-making in small island and coastal regions.

Background: Parents of youth with chronic health conditions face several challenges in supporting their children across contexts. Involvement of parents in a child’s pain management approach is accepted as best practice, yet there is little guidance on how to best parent the child with chronic pain. Prior studies have shown that parents require support and education to effectively care for their children and themselves. This quality improvement program evaluation aimed to evaluate group-level: (1) feasibility of the Creating Bonds program, (2) acceptability and perceived effectiveness of the program, and (3) suggestions for program improvements. Methods: In this quality improvement program evaluation, parents (N = 40) of youth with chronic pain from the United States and Europe were recruited online to participate in a virtual peer-support and educational program, Creating Bonds, offered through the nonprofit organization, Creative Healing for Youth in Pain. Creating Bonds is an 8-week, virtual, supportive, and educational program for parents and caregivers of youth with chronic pain led by a licensed clinical psychologist. A mixed methods approach evaluated the impact of and suggestions for improving the program. Independent samples t-tests were used to examine quantitative items related to understanding of pain, isolation, confusion, distress, relationships, and self-care. Qualitative responses were evaluated for common themes through an inductive thematic analysis. Results: Results indicated that Creating Bonds significantly improved parents’ level of understanding of chronic pain, relationships with others, and self-care, and significantly reduced confusion about parenting a child with chronic pain, stress, and anxiety levels (ps < 0.05). Levels of isolation moderately decreased. Parents qualitatively described the experience as validating, connecting, and educational, with both emotional relief and practical strategies emerging as benefits. Conclusions: Quantitative results and qualitative themes capture the dual role of the Creating Bonds program in providing tangible parenting tools alongside education and critical psychosocial support. Parents entered with uncertainty, a desire for strategies, and hope for connection, and they came away with validation, practical parenting tools, and a community facing similar experiences.

Accurate estimation of aircraft operations, such as takeoffs and landings, is critical for airport planning and resource allocation, yet it remains particularly challenging at non-towered airports, where no dedicated surveillance infrastructure exists. Existing solutions, including video analytics, acoustic sensors, and transponder-based systems, are often costly, incomplete, or unreliable in environments with mixed traffic and inconsistent radio usage, highlighting the need for a scalable, infrastructure-free alternative. To address this gap, this study proposes a novel dual-pipeline machine learning framework that classifies pilot radio communications using both textual and spectral features to infer operational intent. A total of 2489 annotated pilot transmissions collected from a U.S. non-towered airport were processed through automatic speech recognition (ASR) and Mel-spectrogram extraction. We benchmarked multiple traditional classifiers and deep learning models, including ensemble methods, long short-term memory (LSTM) networks, and convolutional neural networks (CNNs), across both feature pipelines. Results show that spectral features paired with deep architectures consistently achieved the highest performance, with F1-scores exceeding 91% despite substantial background noise, overlapping transmissions, and speaker variability These findings indicate that operational intent can be inferred reliably from existing communication audio alone, offering a practical, low-cost path toward scalable aircraft operations monitoring and supporting emerging virtual tower and automated air traffic surveillance applications.

Background/Objectives: This study explores the perceptions, experiences, and expectations of pediatric healthcare professionals regarding the implementation of virtual visits (VVs) in routine pediatric practice. Methods: Using the Consolidated Framework for Implementation Research (CFIR) to analyze individual, organizational, and contextual factors influencing the adoption of pediatric virtual visits, we conducted a descriptive cross-sectional survey distributed nationwide among pediatricians, pediatric nurses, and residents. Results: A total of 308 Spanish healthcare professionals correctly completed the REDCap survey and were included in the analysis. The mean age was 44.3 years, and respondents represented both hospital-based (55.8%) and primary care professionals (44.2%). Overall, 74.8% had previous experience with telephone consultations, while only 11% had performed virtual visits. Most professionals believed VVs could be useful in primary care (81.3%) and hospital out-patient settings (73.9%), especially for follow-up appointments, communication of test results, and chronic-care monitoring. VVs were perceived as more appropriate for older children and adolescents than for infants. Major concerns included poor internet connection (52.6%), and data security (37.4%); however, a particularly relevant finding was the low confidence in using digital tools, particularly among older professionals. Comparative analyses by age and workplace setting identified differences in interest, perceived barriers, and access to technical resources. Hospital-based clinicians reported greater interest in adopting VVs and better access to technological resources compared with primary care professionals. The professionals’ age was inversely associated with interest in VVs. Notably, 72.6% of respondents expressed interest in receiving specific VV training, and nearly 90% believed virtual visits should be offered in their workplace. Conclusions: These findings show a high overall acceptance of VVs but also underline persistent barriers related to infrastructure, digital literacy, and clinical applicability in younger children. Addressing these obstacles through training, improved equipment, and clear clinical protocols will be essential for the successful implementation of pediatric VV programs. Full article

English is the first foreign language most Taiwanese have encountered, yet few have achieved proficient speaking skills. This paper presents a generative AI-based English speaking training system designed to enhance oral proficiency through interactive AI agents. The system employs ChatGPT version 5.2 to generate diverse and tailored conversational scenarios, enabling learners to practice in contextually relevant situations. Spoken responses are captured via speech recognition and analyzed by a large language model, which provides intelligent scoring and personalized feedback to guide improvement. Learners can automatically generate scenario-based scripts according to their learning needs. The D-ID AI system then produces a virtual character of the AI agent, whose lip movements are synchronized with the conversation, thereby creating realistic video interactions. Learning with an AI agent, the system maintains controlled emotional expression, reduces communication anxiety, and helps learners adapt to non-native interaction, fostering more natural and confident speech production. Accordingly, the proposed system supports compelling, immersive, and personalized language learning. The experimental results indicate that repeated practice with the proposed system substantially improves English speaking proficiency. Full article

With the rapid development of the low-altitude economy, UAV logistics delivery systems have garnered widespread attention due to their flexibility and efficiency. The cooperative delivery mode involving a UAV with a suspended payload and a ground vehicle represents a typical networked distribution scenario, whose performance is constrained by the tight coupling of sensing, communication, and control. In practical applications, sensor measurement noise and sudden disturbances propagate through the closed-loop system, severely degrading velocity synchronization and swing angle stability. To address this challenge, this paper focuses on a quadrotor UAV slung-load system and proposes a three-layer nested networked closed-loop control architecture for simultaneous velocity tracking of a moving ground target and swing angle stabilization. First, by establishing the system’s dynamic model, the mapping relationship between cable tension and the payload swing angle (based on sensor feedback) is revealed. Then, by setting the payload velocity as the outermost control objective and constructing a coupled error to drive a virtual swing angle actuator, the direct impact of noise in the raw sensor data is effectively mitigated. Subsequently, the desired acceleration of the UAV is derived through inverse computation, achieving synchronous optimization of velocity tracking and swing angle suppression. Theoretical analysis using Lyapunov methods demonstrates the stability of the closed-loop system in the presence of bounded delays. Simulation results show that the proposed method effectively suppresses payload swing, controls velocity synchronization error, and exhibits strong robustness against sensor noise and sudden disturbance. This study provides a control solution that improves the precision and robustness of sensor-enabled networked control systems in complex dynamic scenarios Full article

Immersive methods and biometric tools provide a rigorous, context-rich way to study how people perceive and choose food. Immersive methods use extended reality, including virtual, augmented, mixed, and augmented virtual environments, to recreate settings such as homes, shops, and restaurants. They increase participants’ sense of presence and the ecological validity (realism of conditions) of experiments, while still tightly controlling sensory and social cues like lighting, sound, and surroundings. Biometric tools record objective signals linked to attention, emotion, and cognitive load via sensors such as eye-tracking, galvanic skin response (GSR), heart rate (and variability), facial electromyography, electroencephalography, and functional near-infrared spectroscopy. Researchers align stimuli presentation, gaze, and physiology on a common temporal reference and link these data to outcomes like liking, choice, or willingness-to-buy. This approach reveals implicit responses that self-reports may miss, clarifies how changes in context shift perception, and improves predictive power. It enables faster, lower-risk product and packaging development, better-informed labeling and retail design, and more targeted nutrition and health communication. Good practices emphasize careful system calibration, adequate statistical power, participant comfort and safety, robust data protection, and transparent analysis. In food science and consumer behavior, combining immersive environments with biometrics yields valid, reproducible evidence about what captures attention, creates value, and drives food choice.

Effective risk communication designed for risk management increases concern and motivates action by providing guidance and specific actions that can be taken. When exposures to environmental contaminants or stressors are ubiquitous or pollutant sources are not easily controlled, also decreasing sustainability, risk communication is focused on actions for risk reduction and avoidance. Three recommended practices (use of virtual exemplars, narrative, and social media) are discussed as tactics and platforms to inform public beliefs and behaviors and to encourage adoption of long-term planning goals that avoid the consequences of future risks. These risk communication strategies appeal broadly to lay audiences, are not limited to scientists and science-trained risk communicators, and are consistent with the US EPA’s SALT Framework, a research-based approach with recommended practices to guide risk communication. The overall strategy is to make risk communication more effective by using approaches that are dynamic, interactive, engaging, and relatable. Full article

Effective training is essential for addressing the continuous requirement for enhancing productivity and safety in construction. Virtual reality (VR) has emerged as a powerful tool for simulating site environments with high fidelity. While previous studies have explored the potential of VR in construction training, there is potential to incorporate advanced construction theories, such as lean principles, which are critical for optimizing work processes and safety. Thus, this study aims to develop an integrated VR-lean training system that integrates lean principles into traditional VR training, focusing on improving productivity and ergonomic safety—two interrelated challenges in construction. This study developed a virtual training environment for scaffolding installation, employing value stream mapping—a key lean tool—to guide trainees in eliminating waste and streamlining workflows. A before-and-after experimental design was implemented, involving 64 participants randomly assigned to non-lean VR or integrated VR-lean training groups. Training performance was assessed using productivity and ergonomic safety indicators, while a post-training questionnaire evaluated training outcomes. The results demonstrated significant productivity improvements in integrated VR-lean training compared to non-lean VR training, including a 12.3% reduction in processing time, a 21.6% reduction in waste time, a 20.8% increase in productivity index, and an 18.4% decrease in number of errors. These gains were driven by identifying and eliminating waste categories, including rework, unnecessary traveling, communication delays, and idling. Additionally, reducing rework contributed to a 7.2% improvement in the safety risk index by minimizing hazardous postures. A post-training questionnaire revealed that training satisfaction was strongly influenced by platform reliability and stability, and user-friendly, easy-to-navigate interfaces, while training effects of the integrated training were enhanced by before-session on waste knowledge and after-training feedback on optimized workflows. This study provides valuable insights into the synergy of lean principles and VR-based training, demonstrating the significant impact of lean within VR scenarios on productivity and ergonomic safety. The study also provides practical recommendations for designing immersive training systems that optimize construction performance and safety outcomes. Full article

Abandoned mines, as emblematic heritage spaces in the process of deindustrialization, preserve collective production memory and serve as vital symbols of local identity. However, current redevelopment practices primarily emphasize physical restoration while overlooking the visual expression and interactive communication of regional culture. This study introduces an augmented reality (AR)–based visual narrative framework that integrates regional culture to bridge the gap between spatial renewal and cultural regeneration. Drawing on semiotics and spatial narrative theory, a multidimensional “space–symbol–memory” translation mechanism is constructed, and a coupling model linking tangible material elements with intangible cultural connotations is established. Supported by technologies such as simultaneous localization and mapping (SLAM), semantic segmentation, and level of detail (LOD) rendering, a multilayer “position–perception–presentation” module system is designed to achieve stable anchoring of virtual and physical spaces and enable multilevel narrative interaction. Through task-oriented mechanisms and user co-creation, the system effectively enhances immersion, cultural identity, and learning outcomes. Experimental validation in a representative mine site confirms the feasibility of the proposed framework. While the study focuses on a single case, the modular and mechanism-based design indicates that the framework can be adapted to cultural tourism, educational communication, and community engagement applications. The key innovation lies in introducing an iterative “evidence–experience–co-creation” model, providing a new methodological reference for the digital reuse of abandoned mines and the sustainable preservation of industrial heritage.
