Abstract
Introduction: While great efforts have been made to determine the quality of life in
hospital staffs, few studies have been conducted to identify the effective
factors on the quality of life of these employees. The purpose of the present
study was to investigate the relationship between workload and quality of life
in hospital personnel.
Material and Methods: In this descriptive-analytical study, 200 staffs were selected randomly
from two large hospitals of Tehran University of medical sciences (Imam
Khomeini and Shariati hospitals). The data collecting tools were three
questionnaires including demographic characteristics,
quality of life (SF-36), and NASA-TLX workload. SPSS software (version 18.0)
was used to analyze the data by descriptive statistics, and Pearson and
Spearman correlation tests.
Results: Based on the
findings of the study, the mean total scores of the quality of life and the
workload were 50±18 and 69.7±13.9, respectively. The results revealed
significant reduction in all dimensions of quality of life in nurses compared
with laboratory and operating room staffs. Meanwhile the nurses’ workload
scores were higher than the two aforementioned groups (p = 0.001). Moreover,
there was a significant inverse relationship between workload and quality of
life in hospital staffs (P=0.004, r = -.306).
Conclusion: The
results of this study highlight the role of managers and supervisors in the
implementation of efficient interventions for improving the quality of life and
workload. Therefore, further researches are required to identify other factors
that affect the quality of life and workload in hospital staffs.

Abstract
Introduction: The present study was aimed to investigate the dimensions of quality of work life and its relation to job satisfaction among workers of automotive industry.
Materials and Methods: In this descriptive-analytical study, 150 workers of an automotive industry in Tehran city were chosen by simple random sampling method. Three questionnaires of demographic characteristics, quality of work life and job satisfaction were employed as data collecting tools. For data analysis, descriptive statistics, t-test, analysis of variance (ANOVA), correlation and regression tests were used.
Results: About 6% of participants evaluated their workload as light, 11.3% as moderate, 60.7% as heavy, and 22% as very heavy. The average of job satisfaction was 55.94± 13.45. 15.3% of subjects had low job satisfaction, 68.7% moderate and 16% reported high job satisfaction. There was a positive and significant relation between quality of work life and job satisfaction (p = 0.001). Meanwhile, general health condition had the highest effect on job satisfaction.
Conclusion: In general, there was a positive and significant relation between the quality of work life and job satisfaction, so that the higher the quality of work life, the higher the job satisfaction of workers. The results also emphasize the role and impact of managers and supervisors for effective interventions to improve quality of work life and job satisfaction. Therefore, further studies are proposed for the identification of other effective factors on the quality of work life and job satisfaction.

Abstract
Objectives: The comfort questionnaire for hand tools (CQH) is a subjective measure for exploring the starting points for improving hand tool design. This study aimed to investigate the psychometric properties of the Farsi version of the CQH.
Methods: In this cross-sectional study, which was conducted among 163 university students, the 17-question CQH was translated into Farsi with a translation back-translation procedure. Content validity was assessed by a panel of 10 experts. Exploratory Factor Analysis (EFA) was applied for determining construct validity. Cronbach’s alpha and Intraclass Correlation Coefficient (ICC) were used for assessing internal consistency and test-retest reliability, respectively. Ceiling and floor effects were also estimated for evaluating the feasibility of the measure.
Results: The CQH showed good content validity. Content validity index (CVI) ranged from 0.80 to 1.00 and Content Validity Ratio (CVR) ranged 0.62-1.00. EFA led to extraction of two factors from the data. The first one was mostly related to functionality and physical interaction and the second one, was generally about adverse body effects. The Cronbach’s alpha was 0.74 and test-retest reliability was 0.74 (95% CI = 0.58 to 0.86) which both were satisfactory. There were no (0%) ceiling and floor effects.
Conclusion: The Farsi version of CQH is an acceptable and useful instrument for evaluating hand tools comfort.

Abstract
Objectives: Providing safety for human resources in the industry is very important. Safety shoes are one of the most common PPEs that protect the foot against potential hazards. This study aimed to evaluate the discomfort and usability of safety shoes in different industries of Mazandaran province to find gaps in the quality of design and improve the design of safety shoes.
Methods: This was a cross-sectional study and was conducted in 2021.This study included employees of 11 different industrial companies that used seven safety shoe brands. They answered two researcher-made questionnaires, LPD (discomfort and general satisfaction) and SFUQ (usability). Data analysis was performed with Spearman rank correlation coefficient while Pearson correlation coefficient, and ANOVA test were also performed.
Results: In total, 226 men with a mean age of 36.33 ± 7.4 years were included in this study. The participants reported the lowest usability for the brand G (3.3 and 3.99), and the least discomfort and the most usability index with the brand A (1.2 and 5.35). Overall, the highest satisfaction was reported for brand A and the lowest satisfaction to brand G.
Conclusion: The findings of this study showed that the main problem in comfort and usability is probably related to shoe molds because the manufacturers of safety shoes import molds from abroad that do not fit the anthropometric characteristics of Iranian users’ feet.

Abstract
Objectives: Awkward posture is a primary cause of musculoskeletal disorders (MSDs) in the dental profession due to the nature of dental activities. This study aimed to examine both observational and device-assisted posture assessment methods used to study dental professionals as well as the reported prevalence of MSDs among them.
Methods: A search was conducted in Scopus, PubMed, and Google Scholar databases for studies performed from 2000 to 2021 using specified keywords. In total, 31 out of the 541 articles found in the initial search were finally included in this study after the exclusion of ineligible articles, duplicates, conference presentations, systematic reviews, and letters to the editor.
Results: Based on the findings, the neck (58%), back and waist (54.9%), and shoulder and hand (29%) areas had the highest reported pain and disorder. Several posture evaluation methods, namely Rapid Upper Limb Assessment (19.4%), Rapid Entire Body Assessment (19.4%), Electromyography (EMG, 13.8%), and Quick Exposure Check (QEC, 8.3%), were the most frequently used methods among all 17 methods employed in the studies.
Conclusion: Among the observational methods, the QEC method was the most practical one as it considered the experiences of dentists and various dimensions of dental tasks. Moreover, the EMG method was the most suitable device-assisted method for the assessment of posture in dentists. The use of questionnaires in conjunction with evaluation methods appears to enhance the understanding and effectiveness of posture assessment.
