Abstract
Introduction: High
prevalence of neck pain has become an important health complain among dental
practitioners which is followed by reduced working performance, burnout and
early retirement. The purpose of this study is to assess the relationship
between individual and occupational risk factors as well as forward head
posture (FHP) with dentist’s neck pain and to determine the priority of these
factors in the development of the neck pain.
Material and Methods: In this cross
- sectional study, 70 dentists of two dental centers in Tehran were examined
with clinical testing of FHP. Individual and job characteristics were collected
by means of a questionnaire. The visual analog scale (VAS) was applied in order
to determine the severity of pain in various parts of the body. Spearman and
Pearson correlation coefficient and multiple linear regressions were used to
examine the relationship and effect of the studied variables in creating the
neck pain.
Results: According to
the results, neck was the most painful part of the body (66.6%). Indeed, 40
(57.1%) of participating dentists were suffering from the forward head posture.
The results of the multiple linear regression showed that the FHP with the
standard coefficient (β= 0.64) was the most influential factor in predicting
the incidence of neck pain.
Conclusion: The FHP has a
greater impact than any other individual and job factors in creating neck pain.
It may be concluded that awkward neck posture is the most important risk factor
for neck pain in static sitting jobs such as dentistry.

Abstract
Introduction: Nursing in hospitals, because of the nature of the work, is a job in which work-related musculoskeletal disorders are highly prevalent. The main cause of musculoskeletal disorder amongst nursing staff is the movement of patients. The aim of this study was to evaluate the risk of musculoskeletal disorders caused by movement of patients in nursing staff of a hospital affiliated with the Allah University of Medical Sciences.
Methods: This cross-sectional study was conducted on 325 nurses from 30 wards of Baqiyatallah hospital during summer 2015. Data were collected using demographic and Body map Musculoskeletal Disorders Questionnaires and PTAI index checklist. Statistical analysis was performed using the SPSS software version 16.
Results: Some musculoskeletal symptoms had been experienced during the last 12 months by 78.3% of the nursing personnel. The results indicated that PTAI index score was significantly associated with musculoskeletal disorders occurrence (P < 0.05)
Conclusions: According to the findings, PTAI is an appropriate tool for musculoskeletal disorders risk identification and assessment due to patient handling in nursing personnel.

Abstract
Abstract: Musculoskeletal disorders are one of the three major disabling diseases in the world. However, the burden of disease in Iran is not yet well-known. Due to the high prevalence of musculoskeletal disorders in students, prevention and control policies should focus on students and health interventions should be carried out based on risk factors. Musculoskeletal problems impose significant economic costs on health and indirectly affect the productivity of people. Therefore, it is essential to provide new approaches aimed at maintaining and improving musculoskeletal health and preventing and managing diseases.

Abstract
Objectives: User engagement with digital technologies refers to the sense of belonging and individual satisfaction. Visual aesthetics, characterized by simplicity and diversity, plays a crucial role in the design of products and online sales strategies. This study investigates the relationship between visual aesthetics and user engagement with in a selected social network.
Methods: This correlational descriptive-analytical study examines the attractiveness of two pages with similar educational content but differing visual aesthetics criteria on one of the social networks. The first page (Researcher-made page) exhibits higher standards of attractiveness compared to the second page (Basic page). Data were collected through online questionnaires and analyzed using SPSS software.
Results: The study involved 116 participants, of whom 91 (78.4%) were female, with an average age of 26.8 ± 2.54 years. The majority of participants held a bachelor's degree (57.8%). The average visual aesthetics scores for the content pages (Researcher-made page) and (Basic page) were 95/92 and 84/9, respectively, indicating that Researcher-made page had greater visual appeal. Furthermore, the user engagement scores for Researcher-made page and Basic page were 107/9 and 100/02, respectively. A significant positive correlation was found between visual appeal and user engagement on both pages (P<0.001), while no significant relationship was observed between gender or education level and these metrics (P>0.05).
Conclusion: This study demonstrates that the visual aesthetics of virtual content pages has a significant impact on user engagement. These findings underscore the importance of adhering to attractiveness criteria in content design, which can be beneficial for content creators, managers, and business owners.

Abstract
Background and Objective: Musculoskeletal disorders, including back pain, are increasingly prevalent among school-aged children. Poor postural habits and improper backpack carriage are significant contributing factors. However, there is currently no comprehensive and standardized tool available to assess children’s knowledge of ergonomics related to spinal health.
Methods: This methodological study involved the development of a questionnaire through a seven-step process. Following the creation of the preliminary version and assessment of face validity, content validity was evaluated using the Content Validity Index (CVI) and Content Validity Ratio (CVR) by ten experts. The reliability of the instrument was assessed via test-retest procedure with 15 students and internal consistency using Cronbach’s alpha coefficient with a sample of 180 students.
Results: The final version of the questionnaire entitled Kids Spine Ergonomics Awareness (KidSEA) comprised 13 items across three domains: "Spinal Anatomy," "Correct Posture," and "Ergonomics of Carrying School Supplies." The CVI and CVR for each item exceeded 0.79 and 0.62, respectively, indicating all items were validated. The Cohen’s kappa coefficient for individual items was above 0.41, and the overall Cronbach’s alpha was 0.74, demonstrating acceptable levels of reliability and internal consistency.
Conclusion: The KidSEA questionnaire is a valid and reliable instrument for assessing knowledge of ergonomic principles related to spinal health in children. It can be utilized to evaluate health literacy concerning spinal care, to design targeted interventions, and to inform educational programs for the studied age group. Further studies are recommended to establish the validity of the instrument across different age groups.
