In an era dominated by artificial intelligence (AI), establishing customer confidence is crucial for the integration and acceptance of AI technologies. This interdisciplinary study examines factors influencing customer trust in AI systems through a mixed-methods approach, blending quantitative analysis with qualitative insights to create a comprehensive conceptual framework. Quantitatively, the study analyzes responses from 1248 participants using structural equation modeling (SEM), exploring interactions between technological factors like perceived usefulness and transparency, psychological factors including perceived risk and domain expertise, and organizational factors such as leadership support and ethical accountability. The results confirm the model, showing significant impacts of these factors on consumer trust and AI adoption attitudes. Qualitatively, the study includes 35 semi-structured interviews and five case studies, providing deeper insight into the dynamics shaping trust. Key themes identified include the necessity of explainability, domain competence, corporate culture, and stakeholder engagement in fostering trust. The qualitative findings complement the quantitative data, highlighting the complex interplay between technology capabilities, human perceptions, and organizational practices in establishing trust in AI. By integrating these findings, the study proposes a novel conceptual model that elucidates how various elements collectively influence consumer trust in AI. This model not only advances theoretical understanding but also offers practical implications for businesses and policymakers. The research contributes to the discourse on trust creation and decision-making in technology, emphasizing the need for interdisciplinary efforts to address societal challenges associated with technological advancements. It lays the groundwork for future research, including longitudinal, cross-cultural, and industry-specific studies, to further explore consumer trust in AI. 展开更多

BACKGROUND: Assessing and evaluating mental health status can provide educational planners valuable information to predict the quality of physicians' performance at work. These data can help physicians to practice in the most desired way. The study aimed to evaluate factors affecting psychological morbidity in Iranian emergency medicine practitioners at educational hospitals of Tehran.METHODS: In this cross sectional study 204 participants(emergency medicine residents and specialists) from educational hospitals of Tehran were recruited and their psychological morbidity was assessed by using a 28-question Goldberg General Health Questionnaire(GHQ-28). Somatization, anxiety and sleep disorders, social dysfunction and depression were evaluated among practitioners and compared to demographic and job related variables.RESULTS: Two hundreds and four participants consisting of 146(71.6%) males and 58(28.4%) females were evaluated. Of all participants, 55(27%) were single and 149(73%) were married. Most of our participants(40.2%) were between 30–35 years old. By using GHQ-28, 129(63.2%) were recognized as normal and 75(36.8%) suffered some mental health disorders. There was a signifi cant gender difference between normal practitioners and practitioners with disorder(P=0.02) while marital status had no significant difference(P=0.2). Only 19(9.3%) declared having some major mental health issue in the previous month.CONCLUSION: Females encountered more mental health disorders than male(P=0.02) and the most common disorder observed was somatization(P=0.006). 展开更多

Since China's reform and accession to the world trade organization (WTO), the international labor division, cooperation, and communication of production have been a direction of the global productivity development. The expansion of the world trade organization and the growth of multinational corporations have promoted China's market economy to head for internationalization; the exchanges of all countries' science and technology, culture, and education have become increasingly frequent and beyond the borders very early, so opening-up has become a world trend. China is playing an important role in this historical process. In this situation, the importance of language translation is increasing day by day, and an unprecedented prosperous situation has especially appeared to the interpretation. In order to accord with this new historical situation, many colleges and universities have set up language translation program and have offered interpretation course. To promote the economic development of China and train more senior interpreters, the studies of interpretation teaching and the improvement of interpretation teaching quality have been particularly important. In this paper, the relationship among memory, note-taking, and psychological factors are analyzed. 展开更多

Based on basic situational research and analysis carried out on 638 college students using network, we found that as many as 20 percent of the students are not only largely dependent on internet, but also addicted to it. Further biography characteristics analyses for different individuals on the four dimensions of the network forced addiction, tolerance, and time management and interpersonal relationship and health, show that there are significant differences in grades, gender with different education levels of their parents. Further researches on discrepancy that addicted groups have in network entertainment addiction, network information, cyber porn, network relations and network transactions addictions also illustrate that significant discrepancies exist in gender, net age, different discipline and other factors. Finally we put forward some correlative measures to solve the problems of college students network psychology from individuals, schools, and society levels. 展开更多

It has since long been known, from everyday experience as well as from animal and human studies, that psychological processes-both affective and cognitive- exert an influence on gastrointestinal sensorimotor function. More specifically, a link between psychological factors and visceral hypersensitivity has been suggested, mainly based on research in functional gastrointestinal disorder patients. However, until recently, the exact nature of this putative relationship remained unclear, mainly due to a lack of non-invasive methods to study the (neurobiological) mechanisms underlying this relationship in non-sleeping humans. As functional brain imaging, introduced in visceral sensory neuroscience some 10 years ago, does provide a method for in vivo study of brain-gut interactions, insight into the neurobiological mechanisms underlying visceral sensation in general and the influence of psychological factors more particularly, has rapidly grown. In this article, an overview of brain imaging evidence on gastrointestinal sensation will be given, with special emphasis on the brain mechanisms underlying the interaction between affective & cognitive processes and visceral sensation. First, the reciprocal neural pathways between the brain and the gut (brain- gut axis) will be briefly outlined, including brain imaging evidence in healthy volunteers. Second, functional brain imaging studies assessing the influence of psychological factors on brain processing of visceral sensation in healthy humans will be discussed in more detail. Finally, brain imaging work investigating differences in brain responses to visceral distension between healthy volunteers and functional gastrointestinal disorder patients will be highlighted. 展开更多

This retrospective study investigated, in two cohorts of subjects living in Southern Italy and awaiting treatment for oral squamous cell carcinoma (OSCC), the variables related to diagnostic delay ascribable to the patient, with particular reference to the cognitive and psychological ones. A total of 156 patients with OSCC (mean age: 62 years, M/F: 2.39 : 1) were recruited at the Universities of Palermo and Naples. Risk factors related to patient delay included: sociodemographic, health-related, cognitive and psychological variables. The analysis was conducted by considering two different delay ranges: dichotomous (≤1 month vs. 〉 1 month) and polytomous (〈1 month, 1-3 months, 〉3 months) delay. Data were investigated by univariate and multivariate analyses and a Pvalue≤0.05 was considered statistically significant. For both delay measurements, the most relevant variables were: 'Personal experience of cancer' (dichotomous delay: P=0.05, odds ratio (0R)=0.33, 95% confidence interval (CI)=0. 11-0.99; polytomous delay: P=0.006, Chi-square= 10.224) and 'Unawareness' (dichotomous delay: P〈0.01, 0R=4.96, 95% CI--2.16-11.37; polytomous delay: P=0.087, Chi-square=4.77). Also 'Denial' (P〈0.01, 0R=6.84, 95% CI=2.31-20.24) and 'Knowledge of cancer' (P=0.079, Chi-square=8.359) were found to be statistically significant both for dichotomous and for polytomous categorization of delay, respectively. The findings of this study indicated that, in the investigated cohorts, the knowledge about cancer issues is strongly linked to the patient delay. Educational interventions on the Mediterranean population are necessary in order to increase the patient awareness and to emphasize his/her key role in early diagnosis of OSCC. 展开更多

The COVID-19 pandemic has caused hundreds of thousands of deaths,millions of infections worldwide,and the loss of trillions of dollars for many large economies.It poses a grave threat to the human population with an excessive number of patients constituting an unprecedented challenge with which health systems have to cope.Researchers from many domains have devised diverse approaches for the timely diagnosis of COVID-19 to facilitate medical responses.In the same vein,a wide variety of research studies have investigated underlying medical conditions for indicators suggesting the severity and mortality of,and role of age groups and gender on,the probability of COVID-19 infection.This study aimed to review,analyze,and critically appraise published works that report on various factors to explain their relationship with COVID-19.Such studies span a wide range,including descriptive analyses,ratio analyses,cohort,prospective and retrospective studies.Various studies that describe indicators to determine the probability of infection among the general population,as well as the risk factors associated with severe illness and mortality,are critically analyzed and these ndings are discussed in detail.A comprehensive analysis was conducted on research studies that investigated the perceived differences in vulnerability of different age groups and genders to severe outcomes of COVID-19.Studies incorporating important demographic,health,and socioeconomic characteristics are highlighted to emphasize their importance.Predominantly,the lack of an appropriated dataset that contains demographic,personal health,and socioeconomic information implicates the efcacy and efciency of the discussed methods.Results are overstated on the part of both exclusion of quarantined and patients with mild symptoms and inclusion of the data from hospitals where the majority of the cases are potentially ill. 展开更多

Methods Sixty cases of primary dysmenorrhea were observed. Before acupuncture treatment, the self-designed confidence questionnaire was used to assess patients' confidence in acupuncture efficacy. Visual Analogue Scale (VAS) was adopted to assess patients' tension level during acupuncture. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were applied to assess the situations of patients' anxiety and depression. Eysenck's personality questionnaire (EPQ) and Cattell sixteen personality factors questionnaire (16PF) were provided to assess the personal characters of patients. Pain intensity, pain duration and accompanied symptoms were recorded before and after acupuncture treatment so as to assess the efficacy. Canonical correlation analysis was used to analyze the relationship between the psychological factors and acupuncture efficacy on primary dysmenorrhea. Results There were significant differences in grading of dysmenorrhea, pain intensity score and pain duration after treatment as compared statistically with those before treatment (all P〈0.001). The standardized coefficients of dominance (r=0.679 7) and anxiety (r=-0.590 6) in personality factors and the reduction of pain duration (r=-0.904 2) among efficacy indices were the highest. The overall correlation coefficients were all lower between the indices of psychological factors and canonical variables of dysmenorrhea efficacy. Conclusion Acupuncture efficacy on primary dysmenorrhea has a certain correlation with dominance and anxiety of patients' personality factors. But, the psychological factors do not play a leading role in acupuncture treatment. 展开更多

Hepatitis B is an infectious disease worthy of attention.Considering the incubation period,psychological inhibition factor,vaccine,limited medical resources and horizontal transmission,an SIRS model is proposed to describe hepatitis B transmission dynamics.In order to describe the behavior changes caused by people's psychological changes,the non-monotonic incidence rate is adopted in the model.We use the saturated treatment rate to describe the limited medical resources.Mathematical analysis shows the existence conditions of the equilibria,forward or backward bifurcation,Hopf bifurcation and the Bogdanov-Takens bifurcation.During the observation of the case data of hepatitis B in China,it is found that there are mainly three features,periodic outbreaks,aperiodic outbreaks,and periodic outbreaks turns to aperiodic outbreaks.According to the above features,we select three different representative regions,Jiangxi,Zhejiang province and Beijing,and then use our model to fit the actual monthly hepatitis B case data.The basic reproduction numbers that we estimated are 1.7712,1.4805 and 1.4132,respectively.The results of data fitting are consistent with those of theoretical analysis.According to the sensitivity analysis of Ro,we conclude that reducing contact,increasing treatment rate,strengthening vaccination and revaccinating can effectively prevent and control the prevalence of hepatitis B. 展开更多

Background Most data about psychological factors relating to acute myocardial infarction (AMI) were obtained from studies carried out in western countries. Results from small descriptive cross-sectional studies in China were inconclusive. The aim of this study was to explore possible associations between psychological risk factors and AMI among the Chinese population with a large-scale case-control study.Methods This study was part of the INTER-HEART China study, itself part of the large international INTER-HEART study of cardiovascular risk factors. In this case-control study, 2909 cases and 2947 controls were recruited from 17 cities.Psychological stress, negative life events, depression and controllability of life circumstances were assessed.Results Cases reported more psychological stress at home or work and odds ratios (ORs) were 3.2 (95% CI 2.1-4.9)for permanent stress and 2.1 (95% CI 1.5-2.8) for several periods of stress respectively. More cases experienced depression compared with controls (19.6% vs. 9.3%) and ORs were 2.2 (95% CI 1.9-2.6). Subjects with 1, 2 and 3 or more depressive symptoms had increased risk of AMI by 2.1, 2.2 and 2.6 fold, respectively, i.e., more depressive symptoms were associated with higher risks of AMI (P for trend <0.0001). Women had a greater risk of AMI from depression (OR 3.0, 95% CI 2.2-4.0) compared to men (OR 2.0, 95% CI 1.6-2.4), P for interaction =0.0364. Negative life events in subjects were associated with increased risk of AMI, OR 1.7 (95% CI 1.4-2.0) for one event and 1.8 (95% CI 1.3-2.4) for two or more events. High levels of controllability of life circumstances reduced the risk for AMI (OR 0.8, 95%CI 0.7-1 .0).Conclusions Several psychological factors were closely associated with increased AMI risk among Chinese population.Psychological stress had a greater AMI risk in men but depression was more significant among women. 展开更多

Objective: To study the impact of De-qi (得气%, obtaining qi) and psychological factors on the efficacy of acupuncture treatment for primary dysmenorrhea, with an attempt to explore the relationship among De-qi, psychological factors, and clinical efficacy. Methods: The patients with primary dysmenorrhea were randomly assigned to a group of acupuncture with manual manipulation (manipulation group, n=67) and an acupuncture group without manipulation (non-manipulation group, n=64). Pain intensity and pain duration were used as measures for evaluating the therapeutic efficacy of the acupuncture treatment. De-qi, the sensations a patient experienced during the acupuncture treatment, was scored on a 4-point scale by the subjects. In addition, the psychological factors, including belief in acupuncture, the level of nervousness, anxiety, and depression, were quantitatively assessed. The personality of the subject was assessed using the Eysenck personality questionnaire (EPQ) and 16 personality factor questionnaire (16PF). Results: Complete data were obtained from 120 patients, 60 patients in each group. There were statistically significant differences in pain intensity (W=2410.0, P〈0.01 ) and pain duration (W=3181.0, P〈0.01) between the two groups. The number of De-qi acupoints (W=1150.5, P〈0.01) and the average intensity of De-qi (W=1141.0, P〈0.01) were significantly higher in the manipulation group as compared with their non-manipulation counterparts. The correlation coefficients between De-qi and therapeutic efficacy of acupuncture were greater than those between psychological factors and therapeutic efficacy. Conclusions: Compared with the psychological factors, De-qi contributed more to the pain-relieving effect of acupuncture in subjects with primary dysmenorrhea. Moreover, manual manipulation is a prerequisite for eliciting and enhancing the De-qi sensations, and De-qi is critical for achieving therapeutic effects. 展开更多

The coronavirus disease(COVID-19)has extremely harmful effects on individual lifestyles,and at present,people must make financial or survival decisions under the profound changes frequently.Although it has been reported that COVID-19 changed decision-making patterns,the underlying mechanisms remained unclear.This mini-review focuses on the impact of the COVID-19 pandemic on in-tertemporal choice,and potential psychological,biological,and social factors that mediate this relationship.A search of the Web of Science electronic database yielded 23 studies.The results showed that under the COVID-19 pandemic,people tended to choose immediate and smaller rewards,and became less patient.In particular,people with negative emotions,in a worse condition of physical health,or who did not comply with their government restriction rules tended to become more"short-sighted"in behavioral terms.Future studies should examine more longitudinal and cross-cultural research to give a broad view about the decision-making change under the COVID-19 pandemic. 展开更多

The ergonomic digital design and evaluation of man-machine system is the main application fields of virtual human technology. Because of the complexity of physical person and uncertainty of fatigue generation mechanism, it is difficult to express a nd evaluate the Virtual Human's fatigue state. This paper summarizes the characteristics of virtual human's fatigue evaluation, such as undeterminable, invisible, the constraint conditions can been used. Viewed from the strengths and weaknesses of preexisting models, metabolic energy expenditure model, dynamic muscle fatigue model and a model to assess fatigue at joint-level using the half-joint concept, this paper puts forward the future development trend that the combination of subjective and objective,diversificationoftheanalyzablemotion,real-timeandvisualexpression. 展开更多
