        Bio-recovery of municipal plastic waste management based on an integrated decision-making framework

        Mohammad M. Shahsavar,Mehran Akrami,Zahra Kian,Mohammad Gheibi,Amir M. Fathollahi-Fard,Mostafa Hajiaghaei-Keshteli,Kourosh Behzadian 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.108 No.-

        Recent years have seen a rapid development in industrialization and urbanization with a huge growth inthe population throughout the world. In this regard, an efficient and robust decision-making frameworkfor the concept of a green city and sustainable development goals to manage municipal plastic wastes isstill needed. This study models a bio-recovery of municipal different plastic wastes management basedon a new integrated Multi-Criterion Decision-Making (MCDM) approach through a case study inMashahd, Iran. The proposed integrated MCDM framework includes the Shannon Entropy (SE),Ordered Weighted Aggregation (OWA), Analytic Hierarchy Process (AHP), Technique for OrderPreference by Similarity to Ideal Solution (TOPSIS) and, ELimination Et Choice Translating REality(ELECTRE) systems in an intelligent way. Through decision-making computations, all criteria areapproved after extraction from the literature review by experts with more than 60% agreement percentage. Different scenarios of economic, energy, and environmental crises are created. One finding of thispaper is to propose a new entrance in economic competition with plastic biodegradation to present anovel, environmental-friendly product with high-quality and low-cost advantages. Another findingdetermines that with an application of plastic wastes bio-recovery, citizens’ satisfaction from urban managementsystem will be increased from 49% to 64%. Whereas, based on the outcomes of this investigation,the rate of municipal waste industries development, smart city goals’ meeting, and rate of hazardousmaterial emission from municipal solid wastes are increased to 58%, 25%, and 70%, respectively. Thedeclared numerical outcomes illustrate the effectiveness of plastic waste bio-recovery on the smart cityconcept.

        The effect of antenatal magnesium sulfate on intraventricular hemorrhage in premature infants: a systematic review and meta-analysis

        ( Yousef Moradi ),( Rozhin Khateri ),( Ladan Haghighi ),( Shoaib Dehghani ),( Shiva Mansouri Hanis ),( Mehrdad Valipour ),( Zahra Najmi ),( Zahra Fathollahy ),( Meisam Allahmoradi ),( Kamyar Mansori ) 대한산부인과학회 2020 Obstetrics & Gynecology Science Vol.63 No.4

        Objective The aim of this systematic review and meta-analysis study was to determine the pooled estimate of the effect of antenatal magnesium sulfate (MgSO<sub>4</sub>) on intraventricular hemorrhage (IVH) in premature infants. Methods Two review authors independently searched all randomized clinical trials from international databases, including Medline (PubMed), Web of Sciences, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Research Registers of ongoing trials (ClinicalTrials.gov), from January 1989 to August 2017. Two independent review authors were responsible for data collection. After extracting the necessary information from the evaluated articles, metaanalysis of the data was performed using Stata version 14. Also, sources of heterogeneity among studies were determined by Meta regression. Results In this study, among 126 articles that were extracted from primary studies, 7 papers that evaluated the effect of MgSO<sub>4</sub> on IVH were eligible for inclusion in the meta-analysis. The results of the meta-analysis showed that pooled relative risk (95% confidence interval [CI]) was 0.80 (95% CI, 0.63 to 1.03) for the effect of MgSO<sub>4</sub> on IVH. Conclusion Results of this study showed that although MgSO<sub>4</sub> had a protective effect on IVH in premature infants, this effect was not statistically significant. Further studies are needed to determine the best dosage, timing, and gestational age to achieve the optimum effect of MgSO<sub>4</sub> on IVH.
