Published: June 2023

LAY SUMMARY

Perinatal mental health disorders (PMHDs) are a common complication of child-bearing that affect about one in seven mothers in the United States. Military life often involves recurring separations from family as a result of deployments. Although much research has focused on how PMHDs affect military families, little is known about military spouses’ experiences in recovering from PMHDs. This qualitative study centred on barriers to and facilitators of PMHD recovery among U.S. female military spouses. Semi-structured focus groups revealed five main barriers (stigma, impacts on service member’s career, lack of support, accessibility, practical and logistical concerns) and three main facilitators (solid support structure, encouragement to seek help, practical and logistical facilitators). Identifying specific barriers to and facilitators of PMHD recovery among military spouses promotes military family psychological health and wellness.

This community service (PKM) aims to provide training to local residents in the manufacture and marketing of processed sorting oranges into dodol, sweets, and tea. Sortir oranges are a type of orange that has good quality and the price is relatively cheaper than ordinary oranges. Therefore, the processing of sorted oranges into value-added processed products such as dodol, sweets and tea can increase the economic value for local residents. This service was carried out in Karang Jaya Village, Selupu Rejang District. After being implemented, this PKM succeeded in providing benefits to the surrounding community. The procedures that have been carried out use the method of observation, socialization, training and continued with direct practice. Local residents who have participated in the training have succeeded in producing quality sorted orange processed products and successfully marketing them effectively. This can be seen from the increase in the income of local residents and the increase in consumer buying interest in processed orange sorting products. The outputs of the activity are (1) the partners' knowledge, skills and income increase, (2) produce sorted orange processed products in the form of dodol, sweets and tea. Thus, training in the manufacture and marketing of processed sorted oranges into dodol, sweets and tea has a positive impact on increasing the income, knowledge and skills of the local community. This is expected to provide long-term benefits for the community and strengthen the local economy.

Introduction: What Competition Does
Authors: Hopkinson Leo , Zidaru Teodor
Published: June 2023

Anthropologists, like neoliberal economists, have often assumed that competition (re)orders society in broadly predictable ways. By contrast, we contend that competition always facilitates changes beyond its anticipated outcomes and disciplinary effects. We argue that the outcomes of competition are contingent on the varied and co-existing interpretations of audiences, arbiters, and competitors about the nature of competition, what is worth competing for, and how to go about it. Hence, although it is often instituted with the intention of authoritatively determining value, generating order, or engineering predefined changes, competition inherently affords alternative and unexpected possibilities for sociality. In doing so, competition mediates divergent social orders and modes of relating, rather than instituting one order or another.

Pembangunan dan Ekonomi Politik Turisme Massal di Daerah Istimewa Yogyakarta
Authors: Muh Kamim Anggalih Bayu
Published: June 2023

This research aimed to explore the transition from community-based tourism into mass tourism which has been initiated by the government. Data was collected through in depth interviews, observation, and secondary data analysis. This research found that the central government has been creating mass tourism since the ‘80s, because the state was interested in making tourism become one of the main incomes after the end of oil boom era. Mass tourism was booming until the end of the ‘90s. Nevertheless, the decrease in international tourist arrival was occurred because of forest fires, economic crises, Bali Bombing I and II, and SARS pandemic. Unfortunately, Yogyakarta’s earthquake in 2006 has hindered the recovery process. One decade after the earthquake, a mass tourism was booming again which was marked by the expansion of hotel construction. There were negative impacts such as lack of water access for public, repression of the labour movement, and policies that neglected public participation. The government continued to develop mass tourism through RPJMD DIY 2017-2022 as the nexus of central and local government interests. Projects from RPJMD DIY 2017-2022 were done by cultures and repressions mobilization, thus lead to another problems such as worsened public interests marginalization, land and labour privatization.

Los captadores de niebla son usados para interceptar agua contenida en la niebla y abastecer de agua a comunidades que habitan en lugares donde este recurso escasea. Se evaluó el uso de captadores de niebla para la captación de agua en un área ubicada en el páramo Pan de Azúcar, Duitama-Boyacá. Se instalaron 60 captadores de niebla, 24 de ellos, con dispositivos para medir los volúmenes de agua interceptados. Los volúmenes de agua captados, se midieron en periodos de 24 horas, por 26 días, durante un año y se usó el modelo geométrico para diferenciar el agua proveniente de la niebla. La precipitación registrada fue mayor a la reportada en la literatura. La precipitación mensual osciló entre 51 y 1198 mm y la temperatura media mensual entre los 6 y 8 °C. Los volúmenes de agua promedio colectados por los 24 captadores de niebla estuvieron entre los 0,02 Lm-2dia-1 hasta los 4,4Lm-2dia-1. Los aportes de agua provenientes de la niebla oscilaron entre los 0,02 y 1,77 mmdía-1. La dirección del viento no afectó la captación de agua y aún se presenta incertidumbre al separar el aporte real de agua proveniente de la niebla a partir de la lluvia orográfica, lo cual, sigue siendo un desafío en los ecosistemas de páramo, por lo que se debe ampliar la investigación, para mejorar los diseños y las eficiencias de los captadores de niebla.

Published: June 2023

Research studies on students' writing anxiety have been done in many EFL teaching contexts. However, there are still very limited scientific articles published about university students' foreign language writing anxiety and the causes in the Indonesian university context. Therefore, this study's main purpose was to analyze students' anxiety in EFL writing and its causes. This study employed a descriptive quantitative method. The study subjects were chosen from the first-year students of the Accounting Study Program of Muhammadiyah University of Palopo academic year 2021-2022, which consists of three classes. Two types of questionnaires were used for collecting the data. The first questionnaire was based on Second Language Writing Anxiety Inventory (SLWAI) developed by Cheng (2014). The questionnaire consisted of 21 items designed to assess students' English writing anxiety. The second questionnaire, the Second Language Writing Fear Inventory (CSLWFI), derived from Rezaei and Jafari's (2014), which was adopted to find out the causes of a feeling of anxiety in writing, consisted of ten questions. SPSS ver. 20 was used to analyze the gathered data. The findings revealed that the student's English writing anxiety was significant, and the key causes were poor understanding of writing concepts, linguistic obstacles, insufficient writing skill practice, and time restrictions.

Background: Race/ethnicity is associated with differences in reproductive history and cognition individually, yet it remains an understudied factor in the relationship between parity and later-life cognition. Objective: To evaluate if the association between parity and cognition differs between racial/ethnic groups. Methods: Participants included 778 older, postmenopausal women from the Health and Nutrition Examination Survey (Latina: n = 178, Non-Latino Black [NLB]: n = 169, Non-Latino White [NLW]: n = 431) who self-reported at least one birth. Cognitive outcomes included working memory, learning memory, and verbal fluency. Covariates included age, education, cardiovascular and other reproductive health factors, adult socioeconomic status (SES) and depressive symptoms. We fit a series of linear models to examine a) whether parity was associated with cognitive functioning, b) if this association varied by race/ethnicity through parity by race/ethnicity interactions, and c) individual parity with cognition associations stratified by race/ethnicity. Results: In the full sample, parity was significantly negatively associated with Digit Symbol Substitution Test (DSST) performance (b = –0.70, p = 0.024) but not Animal Fluency or word-list learning and memory. Tests of race/ethnicity-by-parity interactions were not statistically significant (ps > 0.05). However, stratified analyses by race/ethnicity showed a differential effect of parity on DSST performance, such that parity was significantly negatively associated with DSST performance (b = –1.66, p = 0.007) among Latinas but not in NLWs (b = –0.16, p = 0.74) or NLBs (b = –0.81, p = 0.191). Conclusion: Among Latina, but not NLB or NLW women, greater parity was associated with worse processing speed/executive functioning later in life. Further research is needed to understand the mechanisms driving racial/ethnic differences.

Background: Little is known regarding the differential effects of the apolipoprotein E (APOE) ɛ4 on the regional topography of amyloid and tau in patients with both early-onset (EOAD) and late-onset Alzheimer’s disease (LOAD). Objective: To compare the distribution and association of tau, amyloid, and cortical thickness among groups classified by the presence of APOE ɛ4 allele and onset age. Methods: A total of 165 participants including 54 EOAD patients (29 ɛ4-; 25 ɛ4+), 45 LOAD patients (21 ɛ4-; 24 ɛ4+), and 66 age-matched controls underwent 3T MRI, 18F-THK5351 (THK) and 18F-flutemetamol (FLUTE) PET scans, APOE genotyping, and neuropsychological tests. Data for voxel-wise and standardized uptake values from PET scans were analyzed in the context of APOE and age at onset. Results: EOAD ɛ4- patients showed greater THK retention in the association cortices, whereas their EOAD ɛ4+ counterparts had more retention in medial temporal areas. THK topography of LOAD ɛ4+ was similar to EOAD ɛ4 + . THK correlated positively with FLUTE and conversely with mean cortical thickness, being lowest in EOAD ɛ4-, highest in LOAD ɛ4-, and modest in ɛ4+ groups. Even in the APOE ɛ4+ groups, THK tended to correlate with FLUTE and mean cortical thickness in the inferior parietal region in EOAD and in the medial temporal region in LOAD. LOAD ɛ4- manifested with prevalent small vessel disease markers and the lowest correlation between THK retention and cognition. Conclusion: Our observations suggest the differential effects of the APOE ɛ4 on the relationship between tau and amyloid in EOAD and LOAD.

Published: June 2023

Dealing with classification problems requires the crucial step of feature selection (FS), which helps to reduce data dimensions and shorten classification time. Feature selection and support vector machines (SVM) classification method for banknote dirtiness recognition based on marine predator algorithm (MPA) with mathematical functions was proposed. The mathematical functions were mainly used to improve the optimizatio of MPA for feature parameter selection, and the loss function and kernel function parameters of the SVM are optimized by slime mold optimization algorithm (SMA) and marine predator algorithm. According to the experimental results, the accuracy of identifying dirtiness on the entire surface of the banknote reaches 89.07%. At the same time, according to the image pattern distribution of the banknoteS, the white area image in the middle left of the collected banknote is selected by the same method to select the feature parameters and identify the dirtiness of the banknoteS. The accuracy of dirtiness recognition in the middle left white area reached 86.67%, this shows that the white area in the middle left can basically completely replace the entire banknote. To confirm the effectiveness of the feature selection method, the proposed optimization method has been compared with four other swarm intelligent optimization algorithms to verify its performance. The experiment results indicate that the enhanced strategy is successful in improving the performance of MPA. Moreover, the robustness analysis proves its effectiveness.
An improved TOPSIS-based rank preservation approach for hesitant fuzzy information processing
Authors: Yang Wenguang , Ren Baitong , Xu Bingbing , Pang Xiaona , Liu Ruitian
Published: June 2023

In this study, a novel approach based on the reduction of the attribution and the rank preservation is analyzed, which intends to solve the issue of multi-attribute decision making (MADM) with the hesitant fuzzy information. Firstly, several new concepts are shown to simplify the representation of hesitant fuzzy information, such as single point fuzzification estimated value, and single point fuzzification weighted Euclidean distance. Secondly, a new improved HF-TOPSIS method based on the overall situation and these new concepts are put forward, in which the positive and negative ideal solutions are fixed to calculate the complex hesitant fuzzy decision process. The proposed method in this paper achieves the purpose of compression of the complex hesitant fuzzy information, and the calculation is relatively simple and easy to operate. Finally, two examples are presented to test and verify the credibility and effectiveness of the TOPSIS-Based rank preservation approach, which can achieve the consistency of results before and after evaluation, as well as ensuring rank preservation, while other HF-TOPSIS methods may cause rank reversal problems.
Improving sentence representation for vietnamese natural language understanding using optimal transport
Authors: Nguyen Phu Xuan-Vinh , Nguyen Thu Hoang-Thien , Van Nguyen Kiet , Nguyen Ngan Luu-Thuy
Published: June 2023

Multilingual pre-trained language models have achieved impressive results on most natural language processing tasks. However, the performance is inhibited due to capacity limitations and their under-representation of pre-training data, especially for languages with limited resources. This has led to the creation of tailored pre-trained language models, in which the models are pre-trained on large amounts of monolingual data or domain specific corpus. Nevertheless, compared to relying on multiple monolingual models, utilizing multilingual models offers the advantage of multilinguality, such as generalization on cross-lingual resources. To combine the advantages of both multilingual and monolingual models, we propose KDDA - a framework that leverages monolingual models to a single multilingual model with the aim to improve sentence representation for Vietnamese. KDDA employs teacher-student framework and cross-lingual transfer that aims to adopt knowledge from two monolingual models (teachers) and transfers them into a unified multilingual model (student). Since the representations from the teachers and the student lie on disparate semantic spaces, we measure discrepancy between their distributions by using Sinkhorn Divergence - an optimal transport distance. We conduct experiments on two Vietnamese natural language understanding tasks, including machine reading comprehension and natural language inference. Experimental results show that our model outperforms other state-of-the-art models and yields competitive performances.
Sex Difference in Spinal Muscular Atrophy Patients – are Males More Vulnerable?
Authors: Sun Jianli , Harrington Melissa A. , Porter Ben ,   on behalf of the TREAT-NMD Global Registry Network for SMA
Published: June 2023

Background:

Sex is a significant risk factor in many neurodegenerative disorders. A better understanding of the molecular mechanisms behind sex differences could help develop more targeted therapies that would lead to better outcomes. Untreated spinal muscular atrophy (SMA) is the leading genetic motor disorder causing infant mortality. SMA has a broad spectrum of severity ranging from prenatal death to infant mortality to normal lifespan with some disability. Scattered evidence points to a sex-specific vulnerability in SMA. However, the role of sex as a risk factor in SMA pathology and treatment has received limited attention.

Objective:

Systematically investigate sex differences in the incidence, symptom severity, motor function of patients with different types of SMA, and in the development of SMA1 patients.

Methods:

Aggregated data of SMA patients were obtained from the TREAT-NMD Global SMA Registry and the Cure SMA membership database by data enquiries. Data were analyzed and compared with publicly available standard data and data from published literature.

Results:

The analysis of the aggregated results from the TREAT-NMD dataset revealed that the male/female ratio was correlated to the incidence and prevalence of SMA from different countries; and for SMA patients, more of their male family members were affected by SMA. However, there was no significant difference of sex ratio in the Cure SMA membership dataset. As quantified by the clinician severity scores, symptoms were more severe in males than females in SMA types 2 and 3b. Motor function scores measured higher in females than males in SMA types 1, 3a and 3b. The head circumference was more strongly affected in male SMA type 1 patients.

Conclusions:

The data in certain registry datasets suggest that males may be more vulnerable to SMA than females. The variability observed indicates that more investigation is necessary to fully understand the role of sex differences in SMA epidemiology, and to guide development of more targeted treatments.
A causal approach for detecting team-level momentum in NBA games
Authors: Weimer Louis , Steinert-Threlkeld Zachary C. , Coltin Kevin
Published: June 2023

This paper provides new evidence that team-level momentum exists in the National Basketball Association (NBA). The existence of momentum is one of the most prominent and longstanding questions in sports analytics. But for all its importance to announcers, coaches, and players, existing literature has found little evidence of momentum in professional basketball. This paper exploits a natural experiment in the flow of basketball games: television (TV) timeouts. Since TV timeouts occur at points exogenous to momentum, they enable the measurement of the effect of pauses in the game separate from the effect of strategy changes. We find TV timeouts cause an 11.2% decline in the number of points that the team with momentum subsequently scores. This effect is robust to the size of a run, substitutions, and game context. This result has far reaching implications in basketball strategy and the understanding of momentum in sports more broadly.

Published: June 2023

BACKGROUND: Human emotions vary on a contextual basis. The significance of emotions becomes even more salient in Control Room Operators (CROs) in power plants. OBJECTIVE: This study investigated the effects of emotionally loaded pictures on over/underestimating neutral situations. METHODS: Twenty CROs voluntarily enrolled in the present study. Twenty-one blocks were considered, including ten emotionally loaded and 11 neutral blocks. The stimuli were alternatively submitted to subjects in random order. Each block comprised 13 images from the International Affective Picture System (IAPS), which were shown for 5 seconds. Subjects were required to complete the Self-Assessment Manikin (SAM) after exposure to the first and the last neutral blocks, which were identical. RESULTS: Our analyses showed significant differences between IAPS arousal and SAM1 and SAM2 arousal ratings (p SAM1&IAPS = 0.00, p SAM2&IAPS = 0.02). There was no significant relationship between the first and the second arousals, and emotionally loaded images corresponded to no significant difference in terms of valence. CONCLUSION: The findings suggested that the participants overestimated neutral situations compared with IAPS only in arousal level. Furthermore, CROs can still retain their ability to assess neutral situations in the case of viewing emotional stimuli, especially in valence level, at least half an hour after the first rating. A study design with pure negative/positive and high arousal levels may still provide even more significant results.

BACKGROUND: Risk perception is an intuitive risk about hazards to which people are exposed daily and is related to several factors. In the construction context, there is a need to identify and understand how risk perception is related to these factors; construction companies can implement this information to develop measures for effective risk management. OBJECTIVE: This literature review aims to identify recommendations for future research about factors that may be related to risk perception in construction workers. METHODS: We used the SPIDER tool and searched available electronic databases for the most recent research articles published on risk perception in the construction area. RESULTS: We identified main recommendations for future research: Behavior, environment and working conditions, risk assessment methods, culture, individual and demographic factors, and knowledge. CONCLUSION: Safety behavior is the primary variable of concern in studies related to risk perception in the construction area. Therefore, further research is needed to identify the factors that intervene and impact risk perception to reduce accident rates among construction industry workers.

Published: June 2023

BACKGROUND: Occupational noise exposure is a significant health problem. In addition to hearing impairments, noise as a stressor may cause cardiovascular problems. OBJECTIVE: This study aimed to investigate the effect of exposure to workplace noise on cardiovascular disease risk factors. METHODS: This case-control study was conducted in 2021 in a power plant in Iran. In this study, the health status of 406 employees in both exposed (n = 203) and non-exposed (n = 203) to noise groups was examined for cardiovascular disease risk factors. Also, the trend of changes in the studied variables from 2012 to 2020 in exposed employees was examined. Data were collected from participants’ annual physical examinations and occupational noise exposure measurements. To measure the noise in the present study, the KIMO-DB300 noise level meter was used. Data were analyzed in SPSS-26 software. RESULTS: The results revealed that mean fasting blood sugar (FBS), triglyceride, liver enzyme (SGOT), blood pressure, and body mass index were significantly different in the two groups (p-value<0.05). There was no significant difference in the mean of creatinine, cholesterol, and liver enzyme (SGPT) between the two groups (p-value>0.05). In the exposed group, the mean of all studied variables except diastolic blood pressure was statistically different during the study years (p-value<0.05). CONCLUSION: This study demonstrates that exposure to noise above the permissible level can affect the cardiovascular disease risk factors, so it is recommended to apply engineering and management measures like using Hearing Conservation Programme (HCP) to reduce the risk of these diseases with periodically assessing the health status of employees and timely diagnosis.

Published: June 2023

BACKGROUND: Burnout is not only related to mental health but also to efficiency. Thus, recognizing effective coping strategies has a significant role in improving mental health, the efficiency and productivity of human resources, and making better the level of quality of service. OBJECTIVE: To determine burnout syndrome and examine related factors among the employees of Mashhad University of Medical Sciences. METHOD: This cross-sectional study was conducted among 600 employees at Mashhad University of Medical Sciences. They were selected by a stratified sampling method. The data collection tool was the demographic information and the Burnout Self-Test Maslach Burnout Inventory (MBI) questionnaire. Data were analyzed through SPSS software version 20, using descriptive statistics and independent samples t-tests, one-way ANOVA, and Pearson and Spearman regression. RESULTS: The findings showed that emotional exhaustion (EE) and depersonalization (DP) in the majority of employees were high and personal accomplishment (PA) was low at 88.33% of cases. All participants presented burnout. However, participants aged 35-40 years, those with professional and Ph.D. degrees, and research staff reported higher burnout levels. CONCLUSION: Job burnout and its subscale levels among the employees were high. Job burnout is associated with socioeconomic status that can be affected by individual, organizational, management, and environmental factors. Therefore, this study suggests that employees need to get out of EE and DP conditions for higher job performance. Additionally, further research is required to examine the long-term effects of workplace burnout.

Authors: Bolis Ivan , Eickhoff Maud , Leite Wilza Karla dos Santos , Sznelwar Laerte Idal
Published: June 2023

BACKGROUND: There are companies that can be considered financially successful while creating negative externalities for their workers. This is the case of contact centers. OBJECTIVE: The objective of this article is to investigate the challenges for a service company (such as a contact center) in reconciling its economic and financial objectives with the promotion of the work dimension, guaranteeing workers the possibility of professional, collective, and human development. METHODS: This research has a qualitative ethnographic approach. An activity-centered work analysis method, also known as “Ergonomic Work Analysis” (EWA), was carried out in one of the largest companies in the Brazilian contact center market. RESULTS: The case shows that the achievement of economic-financial objectives of the analyzed company is mainly done by harming the well-being of its workers. In particular, the work of the attendants did not bring any development perspective for them. The prevalence of instrumental rationality in decision-making processes and the asymmetry of power relations between stakeholders are the main reasons why workers’ well-being is not considered. CONCLUSION: The discussion proposes that work-related sciences, such as ergonomics and psychodynamics of work, can bring another type of rationality to the decision-making processes of companies. The work also needs to be sustainable enough to allow the construction and development of professionals, and the health of working population, while improving the company’s performance.

Authors: Toczko Michael , Fyock-Martin Marcie , McCrory Stuart , Martin Joel
Published: June 2023

BACKGROUND: The work-related stress experienced by firefighters is associated with numerous health issues. In the general population, improving physical fitness is associated with improvements in both mental and physical quality of life. OBJECTIVE: The purpose of the study was to examine whether fitter professional firefighters report greater physical and mental quality of life. METHODS: Twenty-three professional firefighters (males = 21, females = 2; age: 36.78±7.12yrs; height: 176.96±5.67 cm; weight: 88.20±16.02 kg; years of service: 8.70±6.62years) volunteered for the study. Participants completed a fitness protocol that included the wall sit and reach, Y-balance test, vertical jump, 1 repetition maximum bench press, pull-ups to failure, push-ups to failure, a plank hold and 1-mile run. The short form 36 questionnaire was used to assess overall quality of life. Firefighters were divided into “high” and “low” groups for physical and mental quality of life. Group differences in fitness parameters were assessed using a multivariate analysis of covariance with gender, age, years of service, height, and body mass as co-variates. RESULTS: Firefighters with lower mental quality of life had lower body fat percentages (p = 0.003), fat mass (p = 0.036), greater fat free mass (p = 0.015), vertical jump height (p = 0.024) and performed more pull-ups (p = 0.003). There were no significant differences in any of the fitness measures between high and low physical quality of life groups. CONCLUSION: The findings indicate that physical fitness of firefighters is not indicative of overall health. Firefighters might use exercise to cope for psychological stress and a holistic approach to improve firefighter quality of life is recommended.

BACKGROUND: Social isolation during the COVID-19 pandemic had a harmful impact on the psychological and physical health of children and teenagers. It is known that interruptions in rehabilitation can cause soft tissue contractures, bone deformities and a decline in motor functions among other complications. OBJECTIVE: The aim of this study was to compare the quality of life and physical activity levels of physically disabled children who continued and did not continue rehabilitation during the COVID-19 pandemic. METHOD: The gross motor levels of 18 children who continued special education and rehabilitation during the COVID-19 pandemic and 18 children who did not continue were determined with the Gross Motor Function Classification System (GMFCS). The International Physical Activity Questionnaire Short Form (IPAQ) and Children’s Quality of Life Scale (PedsQL) questionnaires were administered. RESULTS: The study participants comprised 54.1% females and 45.9% males with a mean age of 9.02 years. No significant differences were detected between the two groups in respect of demographic, clinical and functional characteristics (p > 0.05). The walking parameters of PedsQL (p = 0.02) and IPAQ-SF scores (p = 0.03) were determined to be statistically significantly better in the group that continued rehabilitation. CONCLUSION: The results of this study demonstrated that the quality of life and walking capacity of children who continued rehabilitation during the COVID-19 pandemic were better. Methods should be developed to ensure that rehabilitation is not interrupted during isolation periods of any future pandemic.

BACKGROUND: Internet addiction and physical inactivity are often a major public health problem. OBJECTIVE: This study aimed to determine the relationship between internet addiction (IA) and physical activity (PA) levels of university students in a province in eastern Turkey. METHODS: This cross-sectional study was conducted among 638 students. Internet Addiction Test (IAT), and International Physical Activity Questionnaire (IPAQ) were administered. Chi-square, independent sample t-test, correlation analysis, one-way analysis of variance tests (ANOVA), Tukey HSD test, and multivariate logistic regression analysis were performed. RESULTS: 64.6% of the participants were female, with a mean age of 20.4±2.4 and a mean body mass index (BMI) of 22.3±3.5. 83.4% of the participants were identified as those asymptomatic, 15.2% showed limited symptoms, and 1.4% were pathological internet users according to IAT. A statistically significant difference was found between IAT scores and gender, mother’s education level, father’s education level, academic success, smoking status, and alcohol use (p < 0.05). According to IPAQ scores, 28.1% of the students were inactive, 56.3% were moderate PA and 15.7% had vigorous PA levels. IPAQ total scores of male participants, smokers, and participants with exercise habits were found to be significantly higher (p < 0.05). The mean score IAT and IPAQ was found to be 30.9±18.9 and 1697.7±1847.0. A negative, significant correlation was found between students’ PA and IA levels (p < 0.01). CONCLUSION: It has been observed that IA negatively affects PA. Seminars, conferences, and panels on the internet and physical activity should be organized for university students.

BACKGROUND: Adaption to clinical work during the internship can induce several stressors among medical students, especially in the context of the coronavirus disease 2019 (COVID-19) pandemic. Particularly, job stress could be linked to the development of psychological traits and the formation of the professional identity of medical interns. OBJECTIVE: This study aimed to explore the relationship between job stress, psychological capital, and professional identity through a mediation analysis of Chinese medical interns. METHODS: A descriptive cross-sectional study was conducted in 30 hospitals and clinics in China from June 2021 to March 2022. A total of 665 medical interns filled out questionnaires related to demographic questions, psychological capital, job stress, and professional identity. Data analysis was executed using the IBM SPSS version 22.0 software and its add-in PROCESS Windows version 4.0. RESULTS: The findings indicated a statistically significant mediating effect of psychological capital between job stress and professional identity. Job stress and job stress combined with psychological capital accounted for 5.3% and 37.9%, respectively, of the variance in professional identity. The bootstrapping method corroborated the significance of the indirect effect of job stress through psychological capital (95% bootstrap CI = –4.7921, –2.4345). CONCLUSION: The current findings underscore the need for increased attention on improving the psychological capital of medical interns.
