Abstract Films of (SnS) with a thickness of 400 nm were deposited by the thermal evaporation technique to investigate the influence of annealing temperature on their Physics and CO₂ gas-sensing characteristics. The deposited films were annealed at 200, 300, and 400°C. Structural characterization was performed using XRD, and the obtained results revealed that all samples possessed an orthorhombic crystal structure with a preferred orientation (301). The annealing treatment significantly improved the crystallinity of the films and reduced structural defects and lattice strain. Surface morphology investigations were performed using atomic force microscopy (AFM), which revealed noticeable modifications in… More >

Abstract Amorphous selenium (a-Se) thin films were deposited by vacuum thermal evaporation and investigated in planar photoconductive structures to evaluate their optical and photoelectrical properties in the low-field regime. SEM analysis showed continuous film coverage with a thickness of about 250 nm. Raman spectroscopy and X-ray diffraction confirmed the amorphous structure of the as-deposited films and the formation of trigonal crystalline selenium after annealing. Optical analysis based on transmission and reflectance spectra yielded an optical band gap E g = 1.96   eV and an Urbach energy E U = 0.083   eV ,… More >

Abstract This study focuses on monoclinic system AgSbS₂, employing first-principles methods to calculate the structural, mechanical, optical, and thermodynamic properties. Specifically, geometry optimization yields a stable atomic structure with optimized lattice constants (a = 12.82 Å, b = 4.41 Å, and c = 13.19 Å). Furthermore, electronic structure analysis identifies AgSbS₂ as a direct bandgap semiconductor with a bandgap of 1.456 eV, where the valence and conduction bands primarily originate from Ag-4d, S-3s, and Sb-5p states. Regarding the elastic properties, the calculated elastic constants, combined with Pugh’s B/G criterion, reveal excellent ductility. As for the optical properties, the static More >

Abstract The need for intelligent learning frameworks that can function under stringent limitations relating to privacy, energy, scalability, and trust has increased due to the Internet of Things’ (IoT) and the Internet of Artificial Things’ (IoAT) explosive expansion. Federated Learning (FL), which allows collaborative model training without sharing raw data, has become a potential approach. Non-IID data delivery, inconsistent client engagement, vulnerability to poisoning assaults, and low resource knowledge are among of the significant obstacles that FL alone must overcome. Blockchain integration adds extra overhead in terms of latency, energy consumption, and scalability, but it has… More >

Abstract Phishing has become the most common cybersecurity threat and increasingly exploits human factors rather than technical vulnerabilities. This study examined the relationships between cybersecurity awareness, training frequency, user cyber-hygiene behaviour, organisational culture, risk perception, and self-reported phishing vulnerability and the theoretical basis of this research is the Technology Threat Avoidance Theory (TTAT). A quantitative correlational design was used for data collection and analysis with Pearson correlation in structured questionnaires. The results indicated that the five independent variables have a significant positive relationship with phishing vulnerability. The increased awareness and regular training correlate with greater recognition… More >

Abstract Background: During the upper primary school years, children’s primary interpersonal relationships shift from parent-child interactions to peer relationships. This study investigated the underlying mechanisms between parenting styles and primary school students’ peer relationships, providing theoretical guidance for fostering harmonious peer interactions. Methods: A cluster sampling design was employed, yielding 702 valid responses from fifth and sixth-grade students. Measures included the Short-form Parenting Styles Scale, Peer Relationship Scale, Emotional Intelligence Scale, and Positive Psychological Capital Questionnaire. Data were analyzed using SPSS 27.0 and AMOS 29, with serial mediation models examined via the PROCESS macro. Results: Positive parenting styles… More >

Abstract Backgrounds: South Korea is one of the world’s fastest-aging societies, facing significant challenges in maintaining healthcare quality and accessibility for its rapidly growing elderly population. This study extends the Technology Acceptance Model (TAM) by integrating health empowerment to examine its influence on digital healthcare device adoption among Korean older adults. Specifically, this study aims to investigate how health empowerment is associated with perceived usefulness and perceived ease of use, and how these perceptions subsequently relate to attitude and intention to use digital healthcare devices. Methods: Data were collected from 342 Korean older adults. The analysis followed… More >

Abstract Backgrounds: Children’s mental ill health has risen worldwide in recent years, placing increasing emotional demands not only on autistic children but also on their families. A holistic perspective on supportive therapies besides medical treatment is essential. There is a growing need for research and practice that explore equine-assisted therapy through innovative relational frameworks. This qualitative study had two main aims: first, to understand how parents perceived the social and emotional benefits of their autistic child’s involvement in equine-assisted therapy; and second, to explore how parents experienced positive resonance with their child during simultaneous parent–child involvement in… More >

Abstract Background: Sedentary behavior (SB) has been linked to problematic smartphone use: however, whether different types of SB differentially relate to smartphone addiction risk remains unclear. This study aimed to examine the prevalence of smartphone addiction risk and the independent associations of mentally active and mentally passive SB—across total, weekday, and weekend estimates—with smartphone addiction scores among Saudi adults. Methods: This cross-sectional, web-based study recruited adults aged 18–65 years residing in Saudi Arabia through social media platforms. After excluding participants with missing anthropometric data, implausible body mass index (BMI) values, or total SB >24 h/day, 1037 participants… More >
