Nowadays, using renewable energy (RE) is faster growing by each country. The managerial and designer of supply chain network design (SCND) have to plan to apply RE in pillars of supply chain (SC). This research indicates resilience and sustainable SCND by considering RE (RSSCNDRE) for the first time.A two-stage new robust stochastic optimization is embedded for RSSCNDRE. The first stage locates facility location and RE and the second stage defines flow quantity between SC components. We solve the model by GAMS-CPLEX solver to locate components of SC and RE. Effects of changing conservative coefficient and demand are investigated and by increasing 20% for conservative coefficient, the cost function increase by 0.5%. Also, when demand is high, activating RE is economically feasible and we cannot buy and supply energy by the government power network and have to supply energy by RE. After activating RE, by increasing 20% for demand, the cost function increases by 6%. We contribute fix-and-optimize strategy to define the upper bound for a large-scale problem. The proposed upper bound for the main model is less than 10% and appropriate for estimating the cost of large-scale problems. This research suggested to equip SC by RE that SC becomes resilient against demand fluctuation and sustainable energy resource compatible with sustainable development goal (SGD7).
Background and Aim:This study aimed to determine whether the Full Outline of Unresponsiveness (FOUR) score is an accurate predictorof discharge outcome in traumatic brain injury (TBI) patients and to compare its performanceto Glasgow coma scale (GCS).Materials and Methods:Thisis diagnostic study conducted prospectively on 53 TBI patients admitted to ICU of education hospitals of Medical Science University of Mazandaran during February 2013 to June 2013. Data collection was done with a checklist including biographic, clinical information and outcome. The FOUR score and GCS were determined by the researcher in the first 24 hours. Outcomes considered as in-hospital mortality and poor neurologic outcome (Glasgow Outcome Scale (GOS) 1-3) in discharge time from the hospital.Results:In terms of predictive power for in-hospital mortality, the area under the receiver operating characteristic (ROC) curve was 0/92 (95% CI. 0/81-0/97) for FOUR score and 0/96 (95% CI. 0/87-0/99) for GCS. In terms of predictive power of poor neurologic outcome, the area under the ROC curve was 0/95 (95% CI. 0/86-0/99) for FOUR score and 0/90 (95% CI.0/79-0/96) for GCS as evidenced by GOS 1-3. The cut-off of 6 showed sensitivity and specificity of total four score predicting poor outcome at 0/86 and 0/87 while the cut-off of 4 showed the value of in hospital mortality at 0/90 and 0/90. The total GCS score showed sensitivity and specificity 0/100 and 0/61 at cut-off 7 in predicting poor outcome while in predicting mortality at cut-off of 4 this range was 0/100 and 0/92.Conclusion:The FOUR score is an accurate predictor of discharge outcome in TBI patients. Thus, researchers recommend for therapeutic Schematizationto use in neurosurgical patients at admission day.
Background: Many organizations, especially at the time of accidents, disasters, and critical conditions, cannot provide their services without the presence of volunteers. When accidents and disasters occur, the first persons who normally appear at the scene are citizens. Volunteer citizens with the skills and local knowledge can play important roles when accidents and disasters occur and can provide valuable assistance to the relief forces. The current article aimed at examining the role of volunteer citizens in response to accidents and disasters.
Materials and Methods:The current study examined the published articles from 2000 to 2016 based on the following keywords: informal volunteers in the disasters, challenges facing volunteer citizens in accidents and disasters, informal volunteers and disasters in local and foreign electronic databases including SID, Magiran, Iran Medex, ISC, Google Scholar, PubMed, ISI, and Scopus.Results: Based on the search strategy, 50 articles were examined and the keywords, definitions, volunteer roles, role of volunteers in accidents and disasters, various types of informal voluntary activities, and volunteer citizens' participation were examined.
Conclusion:Studies referred to the roles, definitions, and challenges that informal volunteers face in various stages of accidents and disasters and the obvious point in the research was that more adaptive and comprehensive crisis and emergency management models are needed to utilize the capacities and flexibility of volunteers available within and between communities in disasters, and the network structure management can be helpful to manage the volunteers.
The feasibility process of public construction projects is under the influence of stakeholders, who give direction to public resource allocation. Therefore, the analysis of stakeholders in this process is critical. An inductive qualitative approach was adopted using the grounded theory method to provide a theoretical explanation of stakeholders’ behaviors. Under the insight of structuration theory, the results indicated that the challenges are derived from various interrelated factors, leading to the emergence of improper participation as a macro-structural phenomenon with multilateral interaction with a power-oriented relationship as a micro behavior in the feasibility process at the agency level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
