Background The COVID-19 pandemic accelerated the use of information and communication technologies (ICT) in work settings, raising concerns about technostress and its potential impact on workers’ health and performance. Objective To compare technostress-related assessments associated with ICT use among Spanish teleworkers in 2016 and 2024, identifying changes in perceptions and perceived impacts. Design Retrospective, observational, quantitative, comparative study using two independent cross-sectional samples. Methods A total of 758 Spanish teleworkers completed an online validated questionnaire in 2016 and 2024. Group differences were examined using chi-square tests [with Cramer’s V/ φ and odds ratios (OR) with 95% confidence intervals (CI) for dichotomous outcomes], and independent-samples comparisons ( t -test and Mann–Whitney U with Rosenthal’s r as effect size). Results ICT use for family and leisure purposes was lower in 2024, although associations were small [family: φ = 0.076, OR = 1.38, 95% CI (1.02, 1.88); leisure: φ = 0.095, OR = 1.58, 95% CI (1.12, 2.22)]. Reports that social networks and mobile phones caused problems increased modestly (social networks: V = 0.138; mobile phones: V = 0.121). Ratings of personal experience with ICT shifted significantly ( p < 0.001) with the largest association observed in the study ( V = 0.215). Regarding technostress subscales, perceived autonomy and positive consequences were lower in 2024 (both p = 0.002; | r | ≈ 0.14), whereas negative consequences ( p < 0.001; | r | ≈ 0.21) and perceived capacity to work well using ICT ( p = 0.014; | r | ≈ 0.11) were higher in 2024. Overall, effects were generally small in magnitude but consistent. Conclusion Between 2016 and 2024, Spanish teleworkers showed statistically significant but mostly small changes in technostress-related perceptions. The most consistent pattern was a modest increase in perceived negative consequences alongside slight gains in perceived capacity to manage ICT-related demands. These findings support the need for preventive occupational policies that support healthy teleworking conditions.

Objective This study examined the relationships between parenting styles and behavioral-emotional problems in children with Attention-Deficit/Hyperactivity Disorder (ADHD), investigating mobile phone addiction as a potential mediating mechanism. Methods A cross-sectional design was employed with 232 children diagnosed with ADHD (aged 6–17 years) and their parents. Participants completed the Swanson, Nolan, and Pelham-IV (SNAP-IV) Rating Scale for ADHD symptoms, the Mobile Phone Addiction Self-Rating Scale, the Child Behavior Checklist (CBCL) Brief Form, and the Egna Minnen Beträffande Uppfostran (EMBU) Parenting Style Scale. Mediation analyses were conducted using Hayes’ PROCESS macro with 5,000 bootstrap samples. Results Negative parenting styles (rejection, overprotection) were significantly associated with increased behavioral-emotional problems ( r = 0.41–0.56, p < 0.001), while positive parenting (emotional warmth) showed negative correlations ( r = −0.38 to −0.36, p < 0.001). Mobile phone addiction partially mediated these relationships. The indirect effects were significant (negative parenting: ab = 0.22, 95% CI [0.14, 0.31], accounting for 32.4% of the total effect; positive parenting: ab = −0.16, 95% CI [−0.24, −0.09], accounting for 27.6% of the total effect). Conclusion Mobile phone addiction serves as a significant mediator between parenting styles and behavioral-emotional problems in ADHD children. Interventions targeting both parenting practices and digital device management may be beneficial for improving outcomes in this population.

ABSTRACT Mobile phone purchases increasingly function as identity performances, with consumers attaching meanings of success, modernity, sustainability, and belonging to their devices. These meanings emerge within convergent media ecosystems and omnichannel environments where smartphones act as both product and medium shaping discovery, evaluation, and purchase. In a volatile global market, understanding how identity cues guide channel navigation is strategically critical. This paper introduces the Mediated Omnichannel Identity Flow (MOIF), a framework explaining how cross-channel exposures activate identity constructs, shape evaluation criteria and channel preferences, and translate identity-informed preferences into purchase decisions. Integrating insights from identity signaling, cultural consumption, personalization, influencer mediation, and omnichannel journey theory, MOIF demonstrates how symbolic fit, channel agility, and identity evolution shape consumer pathways. Consumers may discover via YouTube, validate in-store, and purchase online while expecting symbolic coherence. MOIF links cultural media dynamics to identity work and offers strategies for designing identity-aware omnichannel retail systems.

Household consumption expenditures have always been one of the main and most important elements of national income in economic literature. With the advancement of technology, the increase in the quality and prevalence of internet usage has paved the way for digitalization in economies and introduced the concept of digital marketing to the literature. Easy access to digital marketing channels via computers, mobile phones, tablets, etc. and the proliferation of alternatives for consumers can affect consumers' purchase intention and thus household consumption and output. From this standpoint, this study aims is to reveal the interrelation between household consumption expenses, digital marketing and GDP per capita for the Turkish economy through an econometric analysis. For this purpose, the study period is 1993-2022 and the preferred method is Non-Linear Autoregressive Distributed Lag Model (NARDL) method, which allows us to see asymmetric relationships and differ positively from other cointegration tests in this respect. The findings show that household consumption expenditures increase GDP per capita. By contrast, a negative linkage was found between digital marketing and output. Considering the existing literature, the notion that the linkage among the variables we have chosen has not been investigated shows the originality of the study.

This article investigates the profound impact of WhatsApp, a widely used social media platform, particularly among students. Commencing with a definition of social media as computer-mediated tools facilitating information sharing and expression in online communities. This real-time messaging app permits users to exchange unlimited messages, form groups, share multimedia, and connect globally. The literature review section synthesizes various studies examining WhatsApp's impact on academic settings, youth behaviour, and daily lives. While some studies underscore positive effects such as enhanced student attitudes and academic knowledge, others caution against potential drawbacks like procrastination and study disruptions. Objectives of the study pivot around investigating user socio-economic backgrounds, identifying factors influencing WhatsApp usage, and studying its effects on students. The research methodology employs a questionnaire-based survey among IX and X-grade students, revealing that most respondents (16-18 age group) prefer WhatsApp over other social media apps, primarily accessing it via mobile phones. Findings indicate that WhatsApp significantly contributes to connecting with friends and family, with 80% acknowledging its positive impact on academic knowledge. In conclusion, the article highlights WhatsApp's integration into users' lives, presenting a nuanced exploration of its multifaceted influence, from positive academic contributions to potential drawbacks in daily life and social responsibilities. The abstract encapsulates this comprehensive analysis, offering valuable insights for scholars and general readers alike.

Abstract In the 21st century, record-breaking heatwaves have had devastating impacts on people's health, well-being, and livelihoods. In light of this urgent threat, government institutions across the globe are developing guidelines and planned interventions to increase resilience to heatwaves. These measures require an understanding of how people adapt to extreme heat within the constraints of daily life. Existing studies have used large-scale mobility data to characterize heatwave adaptation at a population-level, though these studies skew towards cities and regions in high-income countries, have diverse methodologies that limit generalizability to other contexts, and focus on `activity level' changes without discerning which activities are being altered. Addressing these gaps, this study combines climate reanalysis, mobile phone location, socio-demographic, and physical-geographical data across Brazil, France, India, Nigeria, Turkey, the USA, and China during 2022/2023 summer heatwaves. Google Community Mobility Reports data is used in multivariate multi-level modelling for the first six countries to examine daily activity changes during heatwaves (home, work, transit, grocery/pharmacy, retail/recreation, parks). In China, Baidu data on activity levels is analysed in a complementary multi-level model. The results show a widespread tendency to withdraw into homes but also highlight unequal substitutions of activities, and -- under some circumstances -- visits to potentially cooler locations away from home. This study highlights the global nature of heatwave adaptation and the value of considering adaptation within the context of people's everyday lives.

Excessive use of electronic devices can cause postural changes, pain, and negatively impact generation Z adolescents' quality of life (QoL). The goals of this study were to evaluate and compare between sexes the static posture, postural self-perception, screen time, musculoskeletal pain, and QoL in generation Z adolescents. Cross-sectional study with adolescents. Postural analysis was conducted using the Software SAPo, self-reported posture, back pain, and screen time were assessed with the BackPei-CA, and QoL was evaluated using the Kidscreen-27 questionnaire. Statistical analyses included t-test or Mann-Whitney U test, Spearman's correlation, and adjusted logistic regression, with correction for multiple comparisons (p≤0.05). 408 adolescents were included (204 of each sex), with a mean age of 14.58± 1.98years (males) and 14.56± 1.84years (females). Postural assessment revealed head anteriorization and pelvic misalignment, with females showing greater head and pelvic angular deviations. No significant associations were found between cell phone use and cervical or pelvic alignment. Cell phones/tablets were the most frequently used devices, with higher daily use among females. Musculoskeletal pain was highly prevalent, particularly in the cervical and lumbar regions, and more frequent in females; however, cell phone use was not independently associated with musculoskeletal pain after adjustment. The total sample of adolescents has a goodQoL. Adolescents, especially females, showed head anteriorization and pelvic misalignments, high screen time, and self-perceived inadequate postural habits. Musculoskeletal pain was frequent and more prevalent among females, despite good quality of life. Screen time alone was not associated with postural changes or pain, indicating a multifactorial etiology.

Introduction: The study investigates the relationship between nomophobia and occupational balance among high school students. Nomophobia, or the fear of being without a mobile phone, is increasingly prevalent among adolescents, potentially impacting their daily routines and well-being. This study aimed to examine the relationship between nomophobia levels and occupational balance among high school students. Methods: Sociodemographic data were obtained with a sociodemographic form. The Adolescent Occupational Balance Scale was used to measure occupational balance. The Nomophobia Questionnaire was used to determine nomophobia levels. A total of 258 students participated in the study. Results: Findings reveal that as nomophobia levels increase, students’ ability to manage time and participate in various activities significantly decreases. This study found that students with severe nomophobia showed lower scores in occupational diversity and harmony, indicating that excessive reliance on digital platforms may reduce participation in social and academic activities. Conclusions: The study suggests that high levels of nomophobia may limit individuals’ ability to engage in a variety of meaningful activities, thereby disrupting their occupational balance. Considering occupational balance in future research and intervention strategies is crucial for promoting healthier technology use and improving the overall well-being of high school students. Trial registration: Clinical trial number: not applicable.

Family functioning and mobile phone dependency among adolescents: the mediating role of positive youth development and the moderating effect of physical activity.

Microstrip antennas for Ka-band wireless applications will be thoroughly examined in this research. To utilize 5G wireless applications, a new research topic that has been established is the creation of microstrip patch antennas. Patch antennae are made of different shapes, such as rectangles, circular shapes, triangles, donuts, rings, etc. Many substrate materials are used in patch antenna designs. This article examines the geometric configurations of antennas, the many methods of analysis for attributes of antennas, the dimensions of antennas, the issues that antennas face, and the potential solutions to those challenges. Wireless communication technologies, such as television broadcasts, microwave ovens, mobile phones, wireless local area networks (LANs), Bluetooth, global positioning systems (GPS), and two-way radios, all use it. This article examines the geometric structures of antennas, including several characteristics and materials by which they are constructed, as well as the numerous shapes they can produce. This paper will also examine return loss (S11), bandwidth, voltage standing wave ratio (VSWR), gain, directivity, efficiency, and Bandwidth discussed in the prior studies. In the future, a novel patch antenna can be designed for 5G wireless applications.

In recent years, . This creates a dangerous environment in which people live in fear. In today’s environment, the issue of home security is a cause of concern. The conventional systems used for intruder detection are very costly, and there is also a possibility of false alarms. The problem of false alarms is eliminated by using OpenCV and a mobile phone to develop a system that can effectively detect an intruder by eliminating the movements of objects that are also moving. When an intruder is detected, the system sends an alert to the user through an email, and the video is also stored in the local storage.

The purpose of this study is to analyze the 'factual effectiveness' of the “Notice on Student Life Guidance by Teachers” (hereinafter referred to as the “Notice”), enacted in 2023, within the life guidance field of elementary school homeroom teachers. To this end, this paper systematically examines the factual effectiveness of the “Notice” by categorizing it into two dimensions: “objective effectiveness,” which pertains to the formal existence and hierarchy of the law, and “substantial effectiveness,” which refers to the substantive content. The results of the analysis are as follows: First, in terms of objective effectiveness, the “Notice,” as an administrative rule, entails a risk of undermining legal stability in the process of specifying the vague emotional abuse provisions of the superior “Child Welfare Act.” However, the provisions prohibiting the use of mobile phones, which previously had the potential to violate the principle of statutory reservation, have seen their objective effectiveness strengthened as the recent amendment to the “Elementary and Secondary Education Act” established a clear legal basis. Second, in terms of substantial effectiveness, the study confirms that the system is experiencing distorted implementation due to the absence of human and physical infrastructure for separation measures. Furthermore, it has been confirmed that indiscriminate child abuse reports and malicious complaints are effectively neutralizing legitimate guidance authority. In conclusion, the current “Notice” grants nominal authority to elementary school homeroom teachers but remains limited as it fails to provide the practical means and legal safeguards necessary to support such authority. Accordingly, as alternatives to enhance 'factual effectiveness', this study suggests: amending the emotional abuse provisions of the “Child Welfare Act,” establishing dedicated personnel and designated spaces for separated guidance, and building an effective judicial protection system to counter malicious reports.

Objective This study aimed to comprehensively evaluate changes in lifestyle behaviors and mental health status among rescue workers before and after a major public health emergency, and to identify key modifiable risk factors associated with psychological distress in this critical population. Methods A cross-sectional online survey was conducted between February 23 and March 9, 2020, among rescue workers from a designated unit in China. Using a retrospective design, 1,052 valid responses were collected. Participants reported lifestyle behaviors (smoking, alcohol use, mobile phone use, physical activity, work hours, sleep quality) for both pre- and post-outbreak periods. Mental health was assessed using the PHQ-9 and GAD-7 scales. Statistical analyses included paired comparisons, correlation analysis, stratification by living status and age group, and multivariable regression models. Results Significant adverse lifestyle changes occurred post-outbreak: increases in smoking (13.98% of smokers), alcohol consumption (6.02% of drinkers), mobile phone use (median rise from 2 to 3 h/day), and nocturnal awakenings, alongside declines in physical activity (inactivity rose from 6.56 to 17.68%) and work hours. Mild-to-severe anxiety and depression prevalence were 9.98% and 10.17%. Conclusion Public health emergencies trigger unhealthy lifestyle shifts and significant mental health deterioration among rescue workers, with restrictive environments amplifying these risks. These findings highlight the urgent need for integrated biosecurity strategies combining psychological support, health behavior promotion, and organizational modifications to protect frontline responders and sustain operational readiness during prolonged crises.

In the late nineteenth century, the popularity of cycling prompted a series of medicalised warnings, particularly for women. Among these was "bicycle face": a "nervous condition" attributed to a constant state of stress from attempting to balance a bicycle combined with prolonged facial grimacing, which was believed to result in nervous exhaustion and facial disfigurement. In New Zealand, media coverage peaked between 1895 and 1897, framing it as a threat to women's health, beauty and morals. Related conditions included "cyclemania", "bicycle stoop", "bicycle hump", "bicycle walk" and "bicycle heart". These designations reflected gender norms and anxieties over female independence, rather than medical evidence. The episode mirrors a broader historical pattern in which emerging technologies have triggered dubious health fears which parallel contemporary concerns over the safety of mobile phones, 5G towers and wind turbines. The authors explore the cultural and medical construction of "bicycle face" during the late nineteenth and early twentieth centuries, showing how a small number of rogue physicians used the media to amplify unfounded fears, implanting them into the public consciousness. The historical tendency for health practitioners to superimpose prevailing attitudes and beliefs onto health risks linked to new technologies highlights the need for evidence-based evaluations and vigilance against allowing cultural anxieties to masquerade as novel medical conditions.

This paper investigates how recall periods affect the accuracy of self-employment income data in household surveys conducted in developing countries. Using randomised survey experiments in Cambodia, we compare fishery income estimates obtained through different recall periods – weekly, monthly, seasonal, and yearly – and assess the potential of mobile phone interviews to reduce recall bias. The results reveal substantial recall-induced distortions: longer recall periods systematically lead to overreporting of catch volumes and associated costs, while underreporting the diversity of fish species. Furthermore, recall bias is consistently lower when data are collected via mobile phone interviews compared to traditional face-to-face methods.
