Yadollah Hamidi

Background and Objectives
According to new organizational and management theories, one of the most important elements and tasks of management is creating the necessary environment for creativity to transform the organization. It has been shown that increasing creativity and employee participation improves organizational productivity. Given the importance of governance roles in universities and the potential impact of management studies in these areas, this study aimed to assess the level of creativity among staff and its relationship with their participation in the university.
Methods
This cross-sectional study was conducted in strategic and oversight units directly affiliated with the university presidency. A standard questionnaire, including "Belcher’s Partnership" and "Randsip's Creativity", was used to collect information. Data were analyzed using SPSS16 software, and correlations were determined using t-tests, chi-square, and the Pearson correlation coefficient with a significance level of less than 0.05.
Results
The average creativity score of staff was 180.41, and the participation rate was 113.83, both representing more than 75% of the total score. The results did not indicate a direct correlation between employee creativity and their participation (r = 0.210). There was a difference in creativity between men and women, with women showing higher average creativity scores than men. Employee participation and creativity levels are significantly influenced by the nature of their work.
Conclusion
It is essential to provide a conducive environment for increased participation and creativity, particularly in governance roles where legal constraints may be present. Additionally, our analysis revealed a significant impact of gender on creativity, highlighting that women in supervisory and decision-making roles demonstrate a unique and valuable form of creativity. Therefore, leveraging the presence of women in strategic and oversight units can enhance creativity in positions that require innovative thinking.

Hojatollah Hossainian

Background and Objectives: This study, based on the DIN 91436 standard framework, examines the role of new approaches in realizing sustainable waste management systems and reducing negative environmental impacts.

Materials and Methods: This review study was conducted through a systematic search of international databases (PubMed, Google Scholar, Scopus, ScienceDirect, and Web of Science) and Persian databases (SID, Magiran, IranMedex, and IranDoc) for articles published from 1990 to 2025. The search strategy included a combination of keywords and articles were selected based on inclusion and exclusion criteria, and then the extracted data were categorized and clarified through thematic analysis.

Results: According to studies, green ergonomics is effective through sustainable design of products and processes, reducing waste at source, and increasing recycling and is in line with the prevention stage within the framework of the DIN 91436 standard. Also, by analyzing human-environment interactions, Ergoecology provides a systematic framework for achieving zero waste with an emphasis on technical, social, and environmental dimensions. By combining these two approaches within the framework of the aforementioned standard, an effective path towards a circular economy and sustainable waste management is mapped out, while investigations of chemists, consist of some materials or methods that can be degraded and damage environment overall and are in contrast with zero waste.

Conclusion: Varity of experimental sciences, researches and technologies finally tag various damages to environment that some of them debated in this study. Achieving zero waste requires the integration of the three main pillars of green ergonomics, ergo-ecology, and the implementation framework of the DIN 91436 standard. This integration not only reduces waste and conserves resources, but also promotes human health and environmental sustainability. To institutionalize this approach, it is necessary to expand interdisciplinary research, incorporate its principles into policymaking, and invest in education and culture among all stakeholders.

Objectives: The purpose of this study was to investigate the effects of combined functional exercise training on fear of falling, salivary cortisol levels and quality of life in older adults with fear of falling.
Methods: Forty older adults (16 men and 24 women aged ≥65 years) with fear of falling were randomly assigned to either a control group (n = 20, 8M/12F) or an exercise group (n = 20, 8M/12F). The exercise group participated in an 8-week combined training program consisting of resistance, balance, and flexibility exercises, while the control group maintained their usual lifestyle. Quality of life (LEIPAD questionnaire) and fear of falling (FES-I) were assessed before and 48 hours after the intervention in both groups. Salivary cortisol levels were also measured using the ELISA method.
Results: Fear of falling was significantly lower in the training group compared to the control group after the intervention (p < 0.0001). The 8‑week combined exercise program resulted in a 51% reduction in fear of falling among the older adults (p < 0.0001). Quality of life significantly improved in the training group compared to the control group (p ≤ 0.001). Moreover, salivary cortisol levels were lower in the training group than in the control group (p ≤ 0.0001), while the combined exercises produced a 19.5% reduction in cortisol compared to pre-training levels (p = 0.07).
Conclusion: Combined functional exercise program significantly reduced fear of falling and improved quality of life in older adults, while also inducing a downward trend in cortisol levels. Therefore, such programs can be recommended as safe and effective strategies in geriatric rehabilitation settings

Leila Aghaei

Background and Objectives: Office staff in health networks are exposed to adverse psychosocial factors and work-related musculoskeletal disorders (WMSDs) associated with improper working posture, which may reduce productivity. This study aimed to examine the relationships between psychosocial factors and WMSDs with productivity among administrative staff of a health network and to evaluate the effectiveness of an educational–ergonomic intervention on these outcomes.
Method: This quasi-experimental pretest–posttest study was conducted in 2024–2025 among 150 administrative employees of the Behbahan health network. Data were collected using the Copenhagen Psychosocial Questionnaire (COPSOQ III), the Hersey and Goldsmith ACHIEVE productivity questionnaire, and the Nordic Musculoskeletal Questionnaire (NMQ). Working posture was assessed using the Rapid Office Strain Assessment (ROSA) checklist in a random subsample (n=15). A three-month educational–ergonomic intervention (May–July 2025) was delivered in small groups and covered effective communication/teamwork, stress management, motivation/organizational commitment, social support, and ergonomic principles/healthy work behaviors. Data were analyzed in SPSS-26; statistical significance was set at 0.05.
Results: Overall psychosocial score was positively correlated with total productivity (r=0.633, p<0.01). WMSDs showed significant negative correlations with selected productivity dimensions (p<0.05). After the intervention, psychosocial dimensions and overall productivity improved significantly (p<0.001), with a marked increase in total productivity (2.82 to 4.03; Cohen’s d=1.51). WMSDs decreased significantly (5.36 to 4.24; p<0.001). No significant change was observed in ROSA score (p=0.640).
Conclusion: The educational–ergonomic intervention improved workplace psychosocial conditions and reduced musculoskeletal complaints, resulting in higher productivity among administrative staff in the health network. Controlled studies with longer follow-up are recommended.

Design shoe Last for men with flat feet

Shayan Kafi

Background and Objectives: Flatfoot (Pes Planus) is a prevalent musculoskeletal condition that results in multi-joint pain, premature fatigue, and balance instability. Given that mass-produced footwear in Iran often lacks alignment with Iranian anatomical characteristics, this research aims to determine the appropriate dimensions and indices for designing customized shoe lasts for Iranian men with flat feet. This approach seeks to enhance biomechanical performance and prevent excessive pressure and impact on the feet.
Methods: This applied-developmental study was conducted using a descriptive-analytical methodology. Data were collected through four primary instruments: a questionnaire (n=26), expert interviews, observation and analysis of existing commercial products, and anthropometric measurement of 10 users across 10 specific parameters, including footprint characteristics. The primary goal was to establish standardized dimensions for shoe last design, addressing the current lack of localized industrial standards in the domestic market.
Results: Findings indicate that public awareness regarding flatfoot and its associated corrective products is low, and users are dissatisfied with existing market solutions. Clinical observations confirmed that most Iranian orthopedic centers focus primarily on insole production, with treatment centered on symptom control and pain reduction. Based on the urgent need for optimized products and the collected anthropometric data, a sole pattern and a 3D shoe last model were designed and developed.
Conclusion: The results highlight the importance of enhancing medial longitudinal arch support through specialized shoe last design, which can significantly mitigate complications associated with flatfoot. The final outcome —comprising the sole pattern and the customized shoe last— demonstrates that integrating anthropometric data into engineering design environments provides a robust platform for manufacturers, ultimately leading to improved consumer satisfaction and enhanced foot health.
