Background: Work-related musculoskeletal disorders (WMSDs) impose a heavy burden on individuals, organizations, and governments.Aim: The purpose of this study was to provide information about WMSDs and working posture. This information can be helpful in designing preventive programs.Materials and Methods: The present study is a descriptive-analytical study. 207 subjects participated in this study. For WMSDs investigation and postural assessment during work, Nordic Questionnaire and Rapid Upper Limb Assessment (RULA) method were used, respectively. Gathered data from research variables measurement analyzed using Chi-square test and descriptive statistics. A p value of equal or less than 0.05 took into account to be statistically significant.Results: The most prevalent work–related musculoskeletal disorder was found in lower back region, the percentage for large, medium and small ships staff was 58%, 61.7% and 45.1%, respectively. A significant relationship was found between WMSDs in neck (P=0.001), hands and wrists (P=0.02), back (P=0.04) and knees (P=0.001) and used ship by staff. A higher proportion of level four corrective action, was found in small ship staff.Conclusion: WMSDs are prevalent among staff of all ships. WMSDs are more prevalent in lower back. Also, immediate change in posture and investigation is more necessary in small ship staff.

Objective: This research was conducted to investigate the role of neuroticism, marital empathy, and marital forgiveness in predicting marital satisfaction in married women. Methods: The research method utilized in the present study was the correlation-regression method. The research population comprised married women residing in the geographical area of Lorestan province. The research sample was selected using the multi-stage cluster random sampling method, with a total of 840 participants. The instruments of the present study comprised standard questionnaires, including the Enrich Marital Satisfaction Scale, the NEO-FFI Questionnaire, the Marital Empathy Scale, and the Marital Forgiveness Scale. Employing SPSS software, the acquired data underwent comprehensive analysis. Results: Through multiple linear regression, the model explains 46% of marital satisfaction variance. Standardized coefficients highlight neuroticism's adverse impact, while empathy and forgiveness positively influence satisfaction. A unit increase in forgiveness and empathy corresponds to 0.349 and 0.285 satisfaction units, respectively, whereas neuroticism predicts a 0.324 unit decrease. Hierarchically, forgiveness exerts the greatest influence, followed by neuroticism and empathy. Conclusion: This research emphasizes the need to address neuroticism, encourage marital empathy, and promote forgiveness as essential factors enhancing marital satisfaction, offering valuable insights for individuals and professionals in family counseling, therapy, and policymaking.

The objective of this research is to contribute to the advancement of knowledge in the field of automated accounting and auditing, with a particular focus on the use of blockchain technology. Furthermore, the research will seek to establish a theoretical, conceptual and ethical framework for the aforementioned processes. This research employs a teleological approach, which is defined as a method of inquiry that seeks to identify the purpose or end result of a phenomenon. To this end, a systems approach in the modern approach of Future Technology Analysis (FTA) was used to examine the fundamental concepts underlying blockchain and its applications in accounting and auditing. The fundamental concepts underlying automated accounting and auditing on the blockchain platform were organized and explained within a scientific framework that includes theoretical, conceptual, and ethical considerations. Based on the aforementioned findings, a conceptual, theoretical, and ethical framework was developed and elucidated based on content analysis derived from an understanding of the essential elements of the topic, its underlying rationale, and its operational mechanics. This was accomplished through the use of coding in Atlas.ti v9 and ConceptDraw software. Blockchain capabilities provide a platform for automated accounting and auditing in a scientifically, practically, and logically rigorous manner. The evolution of this research was meticulously designed and presented as a conceptual, theoretical, and ethical framework. The features, alterations, and potentialities of automated accounting and auditing on the blockchain technology platform collectively reinforce the necessity for further investigation, as they demonstrate the significant advantages that this technology offers in comparison to traditional methods. This research takes a novel, forward-looking approach and envisions the use of automated accounting and auditing on the blockchain technology platform. It presents, for the first time, comprehensive scientific frameworks and a systematic model for integrating the understanding of concepts, foundations, processes, and norms.
