Volume 1, Issue 1 (9-2013)
Abstract

Introduction: Lack of attention to the ergonomic measures and standards in making PowerPoint slides can result in visual fatigue, less attention to the content of the lecture and lower quality of training. This study aimed to identify the most popular Persian fonts and font sizes used by students in making PowerPoint slides and to investigate the students' subjective perception of the three features of legibility, formality and attractiveness of these fonts.

Materials and Methods: At first, five most widely used Persian fonts in providing PowerPoint slides were identified in 84 students from Tehran University of Welfare and Rehabilitation Sciences. Then, ten slides were prepared containing simple and familiar sentences based on the five popular fonts and two Different font sizes (24 and 28). Afterwards.40 college students evaluated the eligibility, formality and attractiveness of the fonts and font sizes used in each slide by a seven-item Likert scale. 

Results: One-way ANOVA Revealed significant differences between the students' subjective perception of legibility, formality and attractiveness of the fonts used in the slides. In terms of eligibility and attractiveness, slide 10 (B Titr, 28) was top rated and slide 4 (lotus, 24) was ranked as lowest by the participants. In terms of eligibility and attractiveness, slide 10 (B Titr, 28) was top rated and slide 4 (lotus, 24) was ranked as lowest by the participants.

Conclusion: This study explored the effects of anatomical characteristics of the B Nazanin, B Titr and Lotus Persian fonts on the Students’ perception of legibility, formality and attractiveness. The findings suggested that the type of Selected font in PowerPoint slide design could influence the viewers’ perceptual features of legibility, attractiveness and formality. Thus, disregarding the ergonomic aspects of selected Persian fonts may deteriorate the quality of training. Further studies are needed to examine the ergonomics aspects of wider types of Persian fonts in broader sample sizes. Normal 0 false false false EN-US X-NONE FA

Abstract
Abstract Background: Heat exposure is one of the harmful agents at work environments. Workers in high temperature environments are susceptible to heat strain. The purpose of this study was to evaluate the performance of Iranian cooling vests containing phase change material in hot and humid conditions in the Persian Gulf. Materials and Methods: This interventional study carried out on 6 subjects of oil tanker ship's engine room staff in summer in 2013. The Heat Strain Score Index (HSSI), oral temperature and blood pressure measured with and without the cooling vest wearing for two hours, and data were analyzed by paired t test. Results: The mean oral temperature were 36.98± 0.22 °C (without cooling vest) and were 36.68± 0.68°C (cooling vest) at 30th minutes in heat exposure. The mean oral temperature were 37.06± 0.25 °C (without cooling vest) and were 36.78± 0.16°C (cooling vest) at 60th minutes in heat exposure. (p <0.042) and also HSSI was 12.72 ±3.03 (without cooling vest) and 8.65 ±2.9 (with cooling vest) (p <0.039) but the mean systolic and diastolic blood pressure were not significant statistically with and without the use of cooling vests (p>0.05). Conclusion: Our findings showed that cooling vests with phase change material packs reducing heat strain (oral temperature and perceptual heat) in hot and humid climates in Persian Gulf

Volume 3, Issue 3 (12-2015)
Abstract

Introduction: Musculoskeletal disorders are among the top 10 injuries accounting for absence from work. The Extended Nordic Musculoskeletal Questionnaire (NMQ-E) is one of the many tools used to examine these disorders. The present study was conducted to translate and localize the NMQ-E and to evaluate the face validity and test-retest reliability of its Persian version.

Materials and Methods: The present non-empirical methodological study used the International Quality Of Life Assessment (IQOLA) approach to translate the NMQ-E into Persian. The face validity of the Persian version was examined in a sample of 15 patients with musculoskeletal disorders (MSDs) and its absolute and relative test-retest reliability were examined in a sample of 48 patients using the Standard Error of Measurement (SEM) and the Intra-class Correlation Coefficient (ICC). The Kappa coefficient was also used to measure the inter-rater agreement for nominal variables.

Results: The translation and localization of the NMQ-E was deemed easy and acceptable. All the items of the questionnaire had an acceptable face validity. The Intra-class Correlation Coefficient and the Standard Error of Measurement of the Persian version of the NMQ-E were deemed acceptable (SEM=0.56-1.76 and ICC>0.7) and the Kappa coefficient was calculated as 0.78-1.00. 

Conclusion: The Persian version of the Extended Nordic Musculoskeletal Questionnaire showed an acceptable validity and test-retest reliability for assessing musculoskeletal disorders in Iranian patients.

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.

Volume 11, Issue 4 (1-2024)
Abstract
Objectives: Changes in mental workload are related to performance and level of fatigue, stress, human error, and job dissatisfaction. Questionnaires are simple, accessible, and valid tools for the assessment of mental workload. Therefore, the present study aimed at translation, cultural adaptation, and evaluation of psychometric properties of the Carmen-Q mental workload questionnaire.
Methods: This study was conducted on 296 subjects  (100 women and 196 men) with a mean age of 38.59±7.61 years, working in industrial and administrative sectors in several centers in Saveh. The process of translation and cultural adaptation was carried out in accordance with relevant guidelines and included the stages of forward and backward translation, synthesizing and preparing a final version, piloting, and then final approval of the Persian version. Psychometric properties, including face validity (simplicity and readability), content validity (through content validity index), convergent validity (through correlation with NASA-TLX questionnaire), and internal consistency (using Cronbach's alpha coefficient) were assessed.
Results: The translation, cultural adaptation, and face validity assessment were carried out according to related guidelines, and the text underwent some minor changes. The Content Validity Index values for each of the items and its total (0.914) were acceptable. Cronbach's alpha value was acceptable for all items (0.91) and each subscale (above 0.8). Pearson's correlation coefficient displayed a moderate to good relationship between Carmen-Q and NASA task load index.
Conclusion: The Persian version of the Carmen-Q questionnaire is a valid and reliable tool for evaluating mental workload in Iranian society.
