Identify and prioritize the factors affecting user satisfaction by Kano model and quality function development (QFD) integration methods: A Case Study at a technical and vocational workshop in Tehran
Reza Khani Jazani, Mostafa Hasanvand,
Volume 5, Issue 4 (Journal of Ergonomics 2018)
Abstract
Background: The purpose of this study was to identify and prioritize some factors affecting the trainers' satisfaction of Technical and Vocational Training Organization (TVTO) by integrating QFD and Kano models.
Methods: In this study, 435 trainees, aged 18 to 22 years old, were selected to complete the Kano questionnaire through direct communication and interview with the user in one of the centers of technical and vocational education in Tehran, Iran. In this study, Kano model and quality function development (QFD) integration methods were used to improve the design of technical and vocational institutions' workshops ergonomically and based on the needs of users. After completing the Kano questionnaire by these individuals, the responses were analyzed and the results were entered into the house of quality (HOQ) matrix.
Results: The results of the house of quality (HOQ) matrix in this study showed that design and safe application factor, as one of the most important safety features, had a weight coefficient of j=7.35. However, the furniture adjusting criterion with a weight coefficient of j= 1.09 had the lowest importance from the user's viewpoint. In addition, the thickness of materials and furniture with an absolute significance of AI=52.1 had no significant relation with ergonomics and comfort.
Conclusion: This results showed that both the Kano model and QFD integration method can be used in identifying and determining the priorities of the product design and work environment from the users' perspective.

Evaluation of Musculoskeletal Complaints among Medical Students: An Outcome Related to the Expansion of Virtual Education during the COVID-19 Pandemic
Mounes Khani, Aram Tirgar, Samaneh Pourhadi, Zahra Geraili,
Volume 12, Issue 2 (Iranian Journal of Ergonomics 2024)
Abstract
Objectives: Considering that working with virtual education equipment increased significantly during the COVID-19 era, the purpose of this research was to investigate the association of complaints of musculoskeletal disorders with the use of electronic equipment during virtual education.
Methods: This cross-sectional study was carried out on a group of students in the first four years at Babol University of Medical Sciences, whose courses were mostly presented virtually. Data collection tools included a demographic information form and the standard Nordic questionnaire. Data were analyzed in SPSS22 software using descriptive and inferential statistical indicators, including the Chi-square statistical test. The significance level was considered at 0.05.
Results: The data obtained from 318 medical sciences students showed that 83.6% of them complained of pain in the musculoskeletal system during the past year. More than 21% of the participants had to take medicine, 19.9% needed to visit a doctor, and 4.1% had to use physiotherapy services. The results also showed there was a direct and statistically significant correlation between the frequency of complaints regarding musculoskeletal pain and discomfort in the past week and year and the level of use of virtual teaching devices (P≤0.001).
Conclusion: The expansion of virtual education in universities and the prolonged and continuous use of electronic educational equipment can be effective in increasing the frequency of complaints of musculoskeletal disorders among medical sciences students. Moreover, the lack of regular physical activity, smoking, high levels of stress, insomnia, and fatigue among medical students were also known as other effective factors.

Predicting factors affecting adverse events among nurses using multidimensional modeling
Davood Afshari, Shakiba Babakhani Farshkar, Maryam Nourollahi, Maryam Seyedtabib,
Volume 13, Issue 1 (Iranian Journal of Ergonomics-In Press 2025)
Abstract

Background and Objective: Adverse events, defined as errors occurring during nursing care, have become one of the most serious threats to patient safety and quality of care in hospitals. This study aimed to investigate the role of various factors influencing adverse events among nurses.

Methods: An analytical epidemiological study was conducted on 360 nurses working in public hospitals in Ahvaz. Data were collected using a personal information questionnaire, an environmental factors checklist, the standardized Patient Safety Culture questionnaire, the NEO Personality Inventory, the Copenhagen Psychosocial Questionnaire assessing psychosocial work factors, and a standardized adverse events checklist. Data analysis was performed using SPSS and SMART PLS software.

Results: The most frequently reported adverse events were complaints from patients or their families, while surgical wound infections were reported less frequently. Additionally, 31 nurses (8.6%) reported more than 20 adverse incidents in the past 12 months. The developed model indicated that environmental noise significantly affects both patient safety culture and adverse events, and psychosocial factors influence patient safety culture; however, patient safety culture alone did not have a significant effect on the occurrence of adverse events.

Conclusion: Overall, the prevalence of adverse events among the studied nurses was high. Exposure to environmental noise and psychosocial factors substantially impacts patient safety culture. These findings can inform strategies to improve adverse event management and enhance patient safety culture.
