Abstract
Introduction:
Today, computers are widely used in many homes and workplaces. The relationship
between computer use and musculoskeletal disorders in the neck and upper
extremities has been well documented. Muscle fatigue in the shoulder and arm
regions is one of the most frequently reported problems in computer users.
Supporting the upper extremities has been suggested as a way to reduce the
static load on upper body muscles while using a keyboard. The purpose of this
study was to determine the effect of elbow and forearm support on upper
trapezius muscle fatigue while typing.
Materials and Methods: Eight
students of Bu-Ali Sina University (Hamadan, Iran) participated in this quasi-experimental study. The
surface electromyography activity of the upper trapezius muscle of the dominant
side was recorded in three positions, namely without elbow support, elbow
support with the table, and elbow support with a pad while typing. The muscle fatigue index for the three
typing positions was
calculated based on the median frequency slope of the raw electromyography
signals. Repeated measures analysis of variance (ANOVA) was employed for
statistical analyses.
Results: Median
frequency slope decreased significantly in elbow support with the table in
comparison with non-support position (p = 0.04). There were no significant
differences between elbow support with a pad and other two positions.
Conclusion: These
results suggested elbow support as a mechanism to delay trapezius muscle
fatigue and thus increase task efficiency. More research is required to
determine the advantages or disadvantages of using different pads.

Abstract
Introduction: A significant number of employees of any organization experience burnout, in many different countries. It is obvious that burnout prevention and mental health promotion play an important role in the improvement of the quality of services. One of the strategies that could be useful in reducing premature aging is deployment of a total ergonomics (ergonomics micro and macro). The main objective of this study was to investigate the relationship between variables considered in the context of total ergonomics and burnout.
Methods: The sample was selected from one of the hospitals in Yazd, including various departments with 506 employees. The sample size of 216 was determined according to Morgan. The data were collected through questionnaires and samples were selected through a stratified random sampling method.
Results: The results showed that moderate job burnout and perceived organizational support by the employees was lower than average, and there was a significant negative relationship between burnout and variables involved in comprehensive ergonomics. The study showed that demographic variables of burnout were effective on employees.
Conclusions: This study investigated burnout level, organizational support, organizational justice and physical environment. The reduction of Burnout was assessed by improved total ergonomic (macro and micro ergonomic) conditions. The results obtained in this study correspond with the results of various research studies. At the end of the study, based on the results, suggestions were made to reduce burnout.

Abstract
Objectives: Given the benefits of controlling Body mass index (BMI) on the quality of life, BMI classification based on facial features can be used for developing telemedicine systems and eliminate the limitations of existing measuring tools especially for paralyzed people, that enable physicians to help people online when faced with situations like the COVID-19 pandemic.
Methods: In this study, new features and some previous-work features were extracted from face photos of white, black and Asian people, ages 18 to 81, with normal and overweight BMI. Faces were evaluated in three different steps. First, all faces were considered as one group. Second, they were divided into elliptical, round and square shape groups and third, they were separated based on gender. Then for each step, the performances of Random Forest (RF) and Support Vector Machine (SVM) were evaluated with all of the facial features and with selected features based on Pearson correlation coefficient. Matlab R2015b was used for implementation.
Results: The results revealed that features with higher correlation improved the accuracy of both algorithms. RF best performance using highly correlated features for 97 women and 92 men was in women and square-face groups (91.75% and 87.30% respectively), and SVM best performance was in women group (94.84%), square-face and round-face groups (84.12% and 84% respectively).
Conclusion: Accuracy of BMI classification based on facial features can be improved by categorizing faces into shapes and gender, and selecting appropriate features. The findings can be used for performance enhancement of telemedicine applications, especially for helping the differently-abled.

Abstract
Objectives: Improving employees’ welfare and supporting them has led to the success of the organization. Employees who feel supported by the company will work harder to improve their output and meet the objectives of the company. Finding factors affecting employee well-being has helped organizations to improve performance and achieve success. Therefore, this research has sought to test a model of causal factors affecting employees' well-being with the mediation of self-efficacy among the employees of Razi University of Kermanshah.
Methods: The current applied research was conducted using a descriptive-survey method for data collection. The data collection tool was a questionnaire, which was examined for face validity, convergent validity, and differential validity of the variables. Data analysis was done using a structural equation modeling approach with a partial least squares method through Smart PLs3 software. The statistical population (n=490) included all employees of Razi University of Kermanshah, among whom, 215 individuals were selected as a sample using Morgan's table.
Results: The findings showed that perceived organizational support and role ambiguity were effective on employees' well-being both directly and through the mediation of self-efficacy.
Conclusion: According to the research findings, it can be concluded that ambiguity in employee roles lead to higher emotional burnout and lower well-being, while perceived organizational support can enhance both work engagement and well-being.

Abstract
Objectives: The phenomenon of work-family conflict in organizations leads to important consequences, such as job burnout, emotional burnout, reduced job performance, and decreased individual well-being. Based on this, the aim of the present study was to investigate the effect of work-family conflict on the emotional burnout of teachers in Qom City with the moderating role of organizational support.
Methods: The research was conducted based on structural equation modeling, and the statistical population included all teachers in Qom, totaling 3,864 people, of whom 390 were selected as a sample using the Cochran formula and stratified random sampling method. Three questionnaires of work-family conflict, emotional burnout, and organizational support were used. Research data analysis was performed using SPSS version 26 and Pls software at descriptive (frequency, percentage, mean, and standard deviation) and inferential levels (structural equation model).
Results: The path coefficient of the variables showed that work-family conflict on emotional burnout (Beta=0.625, t=19.45, P=0.000) had a positive and significant effect, and perceived organizational support had a negative and significant effect on emotional burnout (Beta=0.127, t=-2.97; P=0.004).
Conclusion: Organizational support can have a moderating role in the relationship between work-family conflict and burnout. Therefore, the more the individual and his/her environmental conditions can control work-family conflict, and the more support the individual perceives from the organization, the less emotional burnout the individual will experience. Therefore, in addition to the courses it holds to increase teachers' knowledge in specialized fields, the education organization can also hold courses aimed at preparing them psychologically to deal with such stressful situations, which are sometimes unavoidable given today's life and improve their self-control and self-management skills to manage these situations.
