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.

This study aims to investigate Saudi Arabia’s quest for regional hegemony, including its objectives, initiatives, and difficulties. In other words, the degree to which Saudi Arabia has been successful in establishing itself as the region’s dominant power. It is crucial to thoroughly explain Saudi Arabia’s psychological and practical justifications for pursuing regional hegemony in this context. To examine the political discourses, reality, narratives, ambitions, and perspectives of Saudi Arabia and compare these with other regional powers in this area, as well as to highlight a number of context-specific constraints on Saudi Arabia’s aspirations for regional hegemony, is the goal of the research. In addition, it intends to investigate how external powers such as the United States, China, Russia, the European Union, and Turkey influence Middle Eastern regional dynamics based on their own vested interests. This analysis demonstrates that Saudi Arabia’s drive for regional hegemony is mostly restrained by external causes. First, despite its preeminent economic power, the country lacks strong military capabilities to provide a security shield for its friends in this region. Second, the sectarian politics and undiversified economy of the region make it unlikely that secondary nations will receive full public goods. Third, low economic integration, the perception of a common regional threat, the absence of a broad free trade arrangement, the superiority of hard power over soft power, and a lack of mutual trust among regional countries are significantly diminishing the acceptance of Saudi Arabia’s hegemonic role in the region. However, Saudi Arabia is deliberately involving regional partners and coalitions in regional growth. The country takes on the main task for reshaping the Middle East’s economy and elevating this region to success. If Saudi Arabia is successful in fostering regional integration, offering a security shield, encouraging trust building, and collaborating with other states in this region to address shared regional threats, it will have a greater chance than the majority of other states in the region to become the regional hegemon. 

Objective: The objective of this study was to evaluate the effectiveness of Bowen intergenerational family therapy on reducing marital conflicts and enhancing interpersonal forgiveness. Methodology: This research employed a quasi-experimental design with pre-test, post-test, and follow-up phases, incorporating a control group. The statistical population consisted of families who visited the counseling and psychology center in District 1 of Karaj in 2023. Eight families were selected through convenience and voluntary sampling and were randomly assigned to experimental and control groups, each comprising four families. Data were collected using the Differentiation of Self Inventory, the Forgiveness Questionnaire, and the Marital Conflict Questionnaire. The intervention, based on Bowen intergenerational therapy, was conducted over eight weekly group sessions, each lasting 90 minutes. Data analysis involved univariate and multivariate covariance analyses using SPSS software. Findings: The findings revealed that Bowen intergenerational therapy significantly impacted both marital conflicts and interpersonal forgiveness. Specifically, the experimental group showed a marked decrease in marital conflict scores from 154.1 (SD = 11.3) in the pre-test to 139.4 (SD = 10.9) in the post-test, which remained stable at 139.2 (SD = 10.3) in the follow-up phase. Similarly, interpersonal forgiveness scores increased from 78.4 (SD = 5.7) in the pre-test to 114.2 (SD = 9.9) in the post-test and remained at 111.1 (SD = 8.9) during the follow-up phase. These changes were statistically significant compared to the control group, which showed no significant changes. Conclusion: The study concludes that Bowen intergenerational family therapy is effective in reducing marital conflicts and enhancing interpersonal forgiveness. The findings align with previous research, underscoring the therapy's potential to address relational issues and improve emotional regulation within families.
