A review of modelling methodologies for flood source area (FSA) identification

Flooding is an important global hazard that causes an average annual loss of over 40 billion USD and affects a population of over 250 million globally. The complex process of flooding depends on spatial and temporal factors such as weather patterns, topography, and geomorphology. In urban environments where the landscape is ever-changing, spatial factors such as ground cover, green spaces, and drainage systems have a significant impact. Understanding source areas that have a major impact on flooding is, therefore, crucial for strategic flood risk management (FRM). Although flood source area (FSA) identification is not a new concept, its application is only recently being applied in flood modelling research. Continuous improvements in the technology and methodology related to flood models have enabled this research to move beyond traditional methods, such that, in recent years, modelling projects have looked beyond affected areas and recognised the need to address flooding at its source, to study its influence on overall flood risk. These modelling approaches are emerging in the field of FRM and propose innovative methodologies for flood risk mitigation and design implementation; however, they are relatively under-examined. In this paper, we present a review of the modelling approaches currently used to identify FSAs, i.e. unit flood response (UFR) and adaptation-driven approaches (ADA). We highlight their potential for use in adaptive decision making and outline the key challenges for the adoption of such approaches in FRM practises

The Relationship between Hospital Occupational Stress and Prevalence of Depression in Nurses Working in Ilam Hospitals

Introduction: Long-term stress can also lead to mental disorders such as anxiety, depression and physical burnout. The aim of this study was to determine the relationship between hospital occupational stress and prevalence of depression among nurses working in Ilam hospitals. Methods: This is a descriptive-analytic study. The statistical population includes the staff of Imam Khomeini Hospital and martyr Mostafa Khomeini Hospital in Ilam. The study was conducted using a census method. The criteria for entering the individuals were their willingness to participate in this study. The subjects were included in the study with complete satisfaction. Demographic questionnaires, standard questionnaires for occupational stress (HSI), and Beck Depression Inventory were used. Questionnaires were distributed to pre-trained individuals. The data was extracted and analyzed by SPSS software. Results: The findings of this study showed that 31.8 of the samples had a degree of depression. In this study, the rate of depression in men is higher than that of women. According to the results, occupational stress and environmental stress in nursing women were more than men. There is a significant relationship between job stress and stress associated with life with depression (p = 0.001, p = 0.004, respectively). Conclusion: The results of this study always emphasize the point that attention should be paid to stress and stressful occupation of nursing and to think about it and to take preventive measures. Because of the stress of the valve towards all mental illnesses In the event of manpower and the work of a community, it can cause many problems and costs for the individual and society and reduce the quality of the services provided by the nurses

Clinical trials of disease-modifying agents in pediatric MS: Opportunities, challenges, and recommendations from the IPMSSG.

OBJECTIVE: The impetus for this consensus discussion was to recommend clinical trial designs that can deliver high-quality data for effective therapies for pediatric patients, in a reasonable timeframe, with a key focus on short- and long-term safety. METHODS: The International Pediatric Multiple Sclerosis Study Group convened a meeting of experts to review the advances in the understanding of pediatric-onset multiple sclerosis (MS) and the advent of clinical trials for this population. RESULTS: In the last few years, convincing evidence has emerged that the biological processes involved in MS are largely shared across the age span. As such, treatments proven efficacious for the care of adults with MS have a biological rationale for use in pediatric MS given the relapsing-remitting course at onset and high relapse frequency. There are also ethical considerations on conducting clinical trials in this age group including the use of placebo owing to highly active disease. It is imperative to reconsider study design and implementation based on what information is needed. Are studies needed for efficacy or should safety be the primary goal? Further, there have been major recruitment challenges in recently completed and ongoing pediatric MS trials. Phase 3 trials for every newly approved therapy for adult MS in the pediatric MS population are simply not feasible. CONCLUSIONS: A primary goal is to ensure high-quality evidence-based treatment for children and adolescents with MS, which will improve our understanding of the safety of these agents and remove regulatory or insurance-based limitations in access to treatment
