The hospitality industry’s rapid adoption of AI service robots has revealed significant variability in consumer acceptance, highlighting the need for personality-based implementation strategies rather than one-size-fits-all approaches. This study extended the AIDUA (Artificial Intelligence Device Use Acceptance) model by integrating Big Five personality traits and robot design characteristics to understand AI service robot acceptance among South African hospitality consumers. A convergent mixed-methods design combined structural equation modeling of survey data (n = 301) with natural language processing analysis of qualitative responses to examine personality-acceptance pathways and consumer concern themes. Results demonstrated that neuroticism negatively influenced performance expectancy (β = −0.284, p < 0.001), while openness enhanced hedonic motivation and preference for humanoid robots (β = 0.347, p < 0.001). Privacy concerns partially mediated the neuroticism-rejection relationship, while transparency interventions significantly improved acceptance among high-neuroticism consumers (effect size d = 0.98). Four distinct consumer segments emerged: Tech Innovators (23.1%), Pragmatic Adopters (31.7%), Cautious Sceptics (28.4%), and Social Moderates (16.8%), each requiring tailored robot deployment strategies. The extended AIDUA framework explained 68.4% of variance in acceptance intentions, providing hospitality operators with empirically validated guidelines for matching robot types to guest personality profiles, optimizing guest satisfaction while minimizing resistance through culturally sensitive implementation strategies.

Background: Poland was one of only 10 European countries listed teachers as a priority group for vaccination against COVID-19 among National Vaccination Program (NVP). The aim of this study was to analyse post-vaccination symptoms self-reported by teachers vaccinated under the national COVID-19 vaccination programme. Methods: The presented cross-sectional survey was conducted among teachers from all levels of education in public and non-public institutions, who received the SARS-CoV-2 virus vaccination campaign with the vaccine from AstraZeneca as part of the NVP. The survey was conducted using an original, self-designed questionnaire prepared for this study and distributed to teachers in the form of an online survey via email. Bayesian logistic and linear regression were used to estimate the relationship between predictors and dependent variables. Results: A total of 4622 teachers took part in the survey. Of this number, 3,908 teachers declared that they had taken the vaccine. (84.5%). In the study group, self-reported late post-vaccination reactions were very strongly [logBF > 3.4] associated with both gender and age. In contrast, self-reporting of serious late post-vaccination symptoms other than fever was very strongly associated only with gender. Only a small proportion of teachers (from 1.45% to 5.34% depending on age and gender) self-reported immediate post-vaccination reaction (up to 15 minutes after injection). Conclusions: Self-reporting of symptoms is a valuable tool for monitoring the effectiveness and safety of vaccinations and can also contribute to increased satisfaction with the vaccination process, especially when patients are made aware that post-vaccination symptoms are a natural sign of the body's immune response.

In the current economic context, organizations providing automotive repair services face significant challenges in ensuring service quality, operational efficiency, and long-term sustainability. This paper examines the importance of implementing process monitoring systems through the integration of European quality frameworks and Japanese operational principles such as Kaizen, Lean Manufacturing, and Poka-Yoke, to improve the quality of services and increase performance within automotive repair organizations. The research is grounded in Sustainable Development Goals (SDG 9—Industry, Innovation and Infrastructure, and SDG 12—Responsible Consumption and Production), demonstrating how structured quality practices contribute to reducing waste, optimizing processes, and delivering responsible services. The main objectives of the study are to identify the elements that influence the performance of service-specific processes, to improve the quality management practices related to these processes, to eliminate non-conformities, and to enhance profitability and competitive differentiation through service quality assurance. A mixed-methods research design was applied, including direct participatory observation, performance monitoring, and correlational statistical analysis over a six-month period in two Romanian automotive service centers. Key performance indicators (KPIs) such as technician efficiency, rework rate, and order throughput time were collected and analyzed before and after the implementation of selected tools. Findings demonstrate measurable improvements: rework rates decreased from 7.8% to 2.6%, technician efficiency improved from 89% to 105%, and average service completion time was reduced by 1.6 days. Correlation analysis confirmed strong relationships between visual management adoption and rework reduction (r = −0.75), as well as between Lean implementation and technician efficiency (r = +0.89). The study’s novelty lies in its integration of cross-cultural quality management practices into a replicable and sustainable operational model for post-sale service environments. The results validate that implementing monitoring systems, combined with Kaizen, Lean, and Poka-Yoke, supported by visual management and active employee engagement, can lead to superior service quality management, increased customer satisfaction, and long-term organizational success in the automotive repair industry.

Background: Life satisfaction during the perinatal period has gained increasing attention as a relevant indicator of mental health, providing a more complete view of women’s adaptation to motherhood. Methods: This study examines the evolution of life satisfaction across four time points: the third trimester of pregnancy (T1), 8 weeks after birth (T2), 5 months after birth (T3) and 5 years postpartum (T4). A total of 231 women participated in this longitudinal study. Participants completed an ad hoc questionnaire for sociodemographic data and standardized self-report measures assessing different personality variables (attachment style, social support, maternal self-efficacy and positive/negative affect) at T1 as well as the Satisfaction with Life Scale (SWLS) (T1–T4). Statistical analyses were performed in order to evaluate the relationships between variables (Student’s test, ANOVA, Pearson’s correlation), and a linear regression analysis was conducted to explore the contribution of psychosocial variables at each time point. Additional subgroup analyses (employment status and parity) were carried out. Results: Results showed that at the first and second time points, life satisfaction was maintained, but five months after birth (T3), it decreased, and then it changed again five years after birth, increasing to its highest level. The psychosocial variables significantly associated with changes in life satisfaction varied across time points. Differential profiles are also observed depending on the subgroup. Conclusions: These findings suggest that monitoring these variables throughout the perinatal period may help identify women at risk and guide interventions in addition to preventive programs aimed at promoting well-being during the perinatal period and into motherhood.

The quality of teacher education represents a fundamental pillar for effective educational systems. European and Czech educational policies emphasise alignment with labour market demands and continuous professional development of teachers. This study examines the motivations of and barriers faced by secondary school teachers enrolled in a pedagogical study programme at the Czech University of Life Sciences Prague, contextualised within broader European and national strategic frameworks. Employing a mixed-methods approach, the research combined document analysis of international and national educational policy reports with a longitudinal questionnaire survey of 404 bachelor’s level teacher education students. Chi-square tests and sign residual analyses investigated relationships between labour market position, study motivation, and perceived obstacles. Findings reveal that employer requirements primarily drive educational professionals to pursue further qualifications, whilst other occupational groups cite personal interest as their main motivator. Time constraints emerge as the predominant barrier across all groups, followed by inadequate employer support. No significant association was identified between motivation and perceived barriers. Comparative analysis demonstrates Czech teachers’ lower remuneration satisfaction relative to other countries examined in this research. The study concludes that enhanced employer support and targeted policy measures addressing time constraints are essential for effective teacher professional development. Full article

This research explored the connections between Work Support, Satisfaction with Life, and experienced stress among workers from the automotive sector, with a focus on the indirect influence of job support in the relationship between satisfaction with life and perceived stress using a cross-sectional design. The sample comprised 672 employees (52.98% females). Most participants were aged between 30 and 39 years old (33.48%) or between 40 and 49 years old (29.46%). The primary analysis indicated that Work Support had a partial effect on the connection between Satisfaction with Life and Perceived Stress. Satisfaction with Life was found to directly predict Perceived Stress (B = −0.210, p < 0.001), and there was also a significant indirect effect of Work Support (B = −0.036, 95% CI: −0.051, −0.020). Taken in combination, these results provide several contributions to our comprehension of the mechanisms connecting these constructs, particularly in the car industry. Although Satisfaction with Life showed direct links on Perceived Stress, a significant indirect association via Work Support indicates that a portion of these links are influenced by this route, with potential implications for occupational health.

Background: Surgery is often accompanied by fear and anxiety, which can adversely affect recovery and patient’s well-being. Understanding the relationship between surgical fear and anxiety and satisfaction with nursing care can help nurses target interventions that improve perioperative outcomes. Aim: We aimed to investigate surgical fear, preoperative anxiety, and satisfaction with nursing care among hospitalized surgical patients and identify clinical and experiential predictors of surgical fear. Methods: A descriptive cross-sectional study of 100 adult surgical patients was conducted using the Surgical Fear Questionnaire (SFQ), State–Trait Anxiety Inventory (STAI), and a validated Patient Satisfaction with Nursing Care Questionnaire. Descriptive and multivariable regression analyses were performed using IBM SPSS Statistics version 29.0 to explore the associations. Results: Patients reported high overall satisfaction with nursing care but notable preoperative anxiety and moderate surgical fear. Previous surgery, prior anesthesia exposure, longer hospital stay, and limited knowledge of the illness independently predicted greater surgical fear. Conclusions: Despite overall high satisfaction with nursing care, surgical patients experience considerable fear and anxiety. Nurses can reduce the perioperative psychological burden by delivering structured, nurse-led preoperative education, improving communication, and offering emotional support. Integrating such interventions into routine surgical pathways could reduce fear and anxiety and improve the patient experience. Full article

Background: Engaging in physical activity (PA) is especially significant for adolescents, as this is a key developmental stage for establishing lifelong habits. While the physical, mental, and cognitive health benefits of PA are well-documented, less is known about its relationship with adolescents’ life satisfaction (LS). Most existing evidence often involves small sample sizes, focusing particularly on developed regions, and few studies use large-scale comparative data. Methods: This study examines the association between adolescents’ LS and PA using data from the 2022 Programme for International Student Assessment (PISA), the world’s largest comparative education survey of adolescents. Our analysis included 399,794 adolescents from 64 high- and middle-income countries and economies. We used three-level multilevel regressions. Results: We found that, after controlling for individual, family, and school factors, PA is positively and significantly associated with LS. This finding holds for the pooled sample and across the 64 countries analysed. For most countries, we did not find a significant gender moderator effect, suggesting that the positive association between PA and LS did not vary by gender. Conclusions: The findings suggest a global health promotion strategy to promote PA amongst adolescents as a normative developmental process necessary for their well-being and mental health.

Background: Adolescence is a critical developmental stage marked by vulnerability to psychological difficulties. While family relationships, peer bonds, prosocial behaviors, and health-risk factors have been linked to adolescent mental health, few studies have examined their joint effects in clinical pediatric populations. This study assessed demographic, clinical, relational, and behavioral predictors of psychological difficulties in Italian adolescents. Methods: A cross-sectional sample of 177 adolescents (aged 11–14 years) from a pediatric clinic completed the Strengths and Difficulties Questionnaire (SDQ). The Total Difficulties (SDQ TD) score was the main outcome. Associations were tested with ordinary least squares (OLS) and confirmed using robust MM regression. Bootstrap confidence intervals and Benjamini–Hochberg corrections were applied. Sensitivity analyses excluded the Peer Problems subscale to address part–whole overlap. Results: Higher friendship satisfaction was consistently associated with fewer psychological difficulties, confirming its role as a strong protective factor. Prosocial behavior and male sex were also linked to fewer difficulties in initial analyses, though these associations were less stable after correction. Sensitivity analyses further supported the protective value of friendship satisfaction, even when accounting for overlap with peer problems. Despite relatively low overall levels of psychological difficulties, nearly one-quarter of adolescents met the clinical cut-off for eating disorder risk. Conclusions: Friendship satisfaction was the strongest protective factor, while prosocial behavior and sex showed weaker consistency. Findings suggest that distinct aspects of peer relationships jointly shape adolescents’ psychological outcomes. Interventions promoting social functioning may support mental health in clinical youth populations. Full article

This study proposes a Personalized Deep Learning-Based Sleep Recommendation System Using Lifelog Data (PDSRS-LD). Traditional sleep research primarily relies on bio signals such as EEG and ECG recorded during sleep but often fails to sufficiently reflect the influence of daily activities on sleep quality. To address this limitation, we collect lifelog data such as stress levels, fatigue, and sleep satisfaction via wearable devices and use them to construct individual user profiles. Subsequently, real sleep data obtained from an AI-powered motion bed are incorporated for secondary training to enhance recommendation performance. PDSRS-LD considers comprehensive user data, including gender, age, and physical activity, to analyze the relationships among sleep quality, stress, and fatigue. Based on this analysis, the system provides personalized sleep improvement strategies. Experimental results demonstrate that the proposed system outperforms existing models in terms of F1 score and Average Precision (mAP). These results suggest that PDSRS-LD is effective for real-time, user-centric sleep management and holds significant potential for integration into future smart healthcare systems. Full article

Background/Objectives: Depression is common in young doctors. Religion/spirituality, vocation, and family might protect against it. The objective of this study was to evaluate mental health, spirituality, and flourishing (a multi-dimensional assessment of well-being) in new medical residents. We also evaluated the associations of baseline characteristics with flourishing. Methods: We conducted a cross-sectional survey in 743 new medical residents who responded to (1) a questionnaire addressing mental health, vocation, spirituality, family, and religion and (2) the “Secure Flourish Index”, which assesses happiness/life satisfaction, physical/mental health, meaning/purpose, character/virtue, social relationships, and financial/material stability. Results: The mean age was 25.7 ± 4.0, and 526 (70.8%) were females, 157 (21.1%) had felt depressed, and 22 (3.0%) had suicidal ideation. The mean values for assessments of vocation and family were very high (>9.2), while religion and spirituality had intermediate values (5.2–6.5). Participants with depression or suicidal ideation had lower assessments in all four of the aforementioned domains, although differences were only significant for depression–religion (p = 0.03). The average “Secure Flourish Index” was 8.2 ± 0.9. There were lower levels of flourishing in males and in those with depression or suicidal ideation, with p-values < 0.001. Flourishing had a correlation with vocation and family (with r-values of 0.3–0.4) and with spirituality and religion (with r-values of 0.25–0.27), with p-values ≤ 0.001. Conclusions: Resident well-being is critical for physicians and healthcare quality. Spirituality and religion may serve as a protective resource, enhancing flourishing. Our study shows that new medical residents seem to have high value assessments for vocation and family importance and intermediate values for religion and spirituality. The mean flourishing scores were high, but were lower in males and in those with depression. Flourishing seems to be correlated with vocation, family, spirituality, and religion, but these associations need to be confirmed with validated screening tools. Full article

Previous cross-sectional studies have explored associations between basic psychological need satisfaction, fear of missing out (FoMO), and depression. However, the longitudinal nature of these relationships and their underlying mechanisms remain unclear. This study aimed to utilize longitudinal tracking methods to investigate the relationships among basic psychological need satisfaction, fear of missing out, and depression in university students. Longitudinal data collection was conducted among 750 university students (mean age = 18.12 ± 0.73) in China over two years at three time points. Participants were investigated using paper–pencil survey versions of the Basic Psychological Needs Scale, the Fear of Missing Out scale, and The Center for Epidemiological Studies Depression Scale. The results revealed that, over the two-year study period, basic psychological need satisfaction (β = −6.239, p < 0.001) among university students demonstrated a declining trend, while FoMO (β = 1.360, p < 0.001) and depression (β = 3.602, p < 0.001) demonstrated an upward trend. The initial levels and development rates of basic psychological need satisfaction directly predicted the initial levels (β = −0.236, p = 0.031) and development rates of depression (β = −0.144, p < 0.001; β = −0.181, p = 0.005). The initial level of FoMO mediated the relationship between basic psychological need satisfaction and depression (β = −0.132, p = 0.007; β = −0.104, p = 0.036), and this mediating effect did not exhibit significant gender differences. These findings help to reveal the temporal relationships among the three variables from a dynamic perspective, providing important practical guidance for mental health education in universities.

Parking shortages and high costs in Chinese central business districts (CBDs) remain major urban challenges. Emerging automated vehicles (AVs) are expected to diversify parking options and mitigate these problems. However, AV users’ parking preferences and their influencing factors within existing urban zoning frameworks remain unclear. This study examines Nanjing as a representative case, proposing six distinct AV parking modes. Using survey data from 4644 responses collected from 1634 potential users, we employed nested logit models and random forest algorithms to analyze parking choice behavior. Results indicate that diversified AV parking modes would significantly reduce CBD parking demand. Users with medium- to long-term needs prefer home-parking, while short-term users favor CBD proximity. Key influencing factors include parking service satisfaction, duration, congestion time, AV punctuality, and individual characteristics, with satisfaction attributes showing the greatest impact across all modes. Comparative analysis reveals that random forest algorithms provide superior predictive accuracy for parking mode importance, while nested logit models better explain causal relationships between choices and influencing factors. This study establishes a dual analytical framework combining interpretability and predictive accuracy for urban AV parking research, providing valuable insights for transportation management and future metropolitan studies.

This study investigates the complex interplay between internal communication, psychological well-being, and job satisfaction, as well as their influence on employee retention and job performance in Romania’s post-pandemic hospitality sector. In this study, data were collected from 350 employees across hotels, restaurants, and resorts. A Covariance-Based Structural Equation Modeling (CB-SEM) approach was employed for the analysis. Findings suggest that both internal communication and psychological well-being are significant positive predictors of job satisfaction. In turn, job satisfaction is a powerful driver of both employee retention and job performance. A key finding is that job satisfaction fully mediates the relationship between psychological well-being and job performance, with no direct effect observed between the latter two constructs. These results underscore that fostering an employee-centric environment is crucial for achieving social sustainability, directly supporting global Sustainable Development Goals (SDG 8: Decent Work and Economic Growth and SDG 3: Good Health and Well-being). Theoretical and practical implications, as well as limitations and future research directions, are discussed. Full article

The taste, aroma, and sensory characteristics of cherries are key factors influencing consumer acceptance. In this study, the sensory evaluation, biochemical characteristics, and their relationships with consumer satisfaction of several representative cherry cultivars were analyzed during cold storage to establish systematic quality evaluation parameters. Targeted metabolomics analysis revealed significant differences in physiological quality and metabolic profiles among the tested cultivars. Specifically, ‘Benitemari’ demonstrated more contents of soluble solids and titratable acid, while ‘Tieton’ and ‘Skeena’ showed higher concentrations of volatile organic compounds and polyphenolics. Furthermore, hexanal and (E)-2-hexenal were identified as the dominant VOCs, while cyanidin-3-O-rutinoside was confirmed as a major phenolic component across the cultivars. Finally, the comprehensive score of the principal component model was significantly positively correlated with the scores of firmness, chewiness, sweetness, sourness, and taste and bitterness in the sensory evaluation. The results were expected to provide valuable guidance for standardizing the sweet cherry supply chain and cultivating high-quality sweet cherry cultivars. Full article
