Typically, hydrological problems require approaches capable of describing and simulating part of the hydrological system, or the environmental consequences of natural or anthropic actions. Tools such as Multiagent System (MAS) and Rainfall-Runoff Model (RRM) have been used to help researchers to develop and better understand water systems. Thus, this study presents a Systematic Literature Review (SLR) on the joint use of MAS and RRM tools, in the context of hydrological problems. SLR was performed based on a protocol defined from the research question. Initially, 79 papers were found among six bibliographic databases. This total was reduced over four stages of selection, according to exclusion criteria. In the end, three papers were considered satisfactory within the scope of the research, where they were summarized, analyzed, and compared. While the MAS and RRM tools can interact with their results in a coupled model, SLR showed that there are still major challenges to be explored concerning the dynamics between them, as the steps of scales and validation. However, the coupling of MAS and RRM can provide an interesting alternative tool to analyse decision-making about water resources management systems.

Background:Juvenile idiopathic arthritis (JIA), one of the most common chronic diseases in children, can be classified in seven different categories according to its onset presentation. Concerns about pregnancy outcomes play a secondary role in disease approach. However, recent data showed an increased risk of pre-term birth in women with JIA instead the small patient samples analysed.Objectives:In this review, our aim is to describe the current available knowledge on JIA adverse, maternal and fetal, outcomes.Methods:A systematic literature review was conducted since January of 2000 until December 2020, by searching the PubMed and Embase bibliographic databases. The search was limited to articles in English language, presenting a comparator group (healthy individuals or patients without known auto-immune rheumatic diseases) and at least one clinical outcome of interest. Two independent reviewers screened the titles and abstracts followed by a full-text review to assess papers regarding their eligibility.Results:Ten observational studies out of 1560 references, fulfilled the inclusion criteria, of which, 9 were retrospective and 1 prospective. A total of 6.214 women with JIA (with 6.811 pregnancies) and 18.659.513 healthy controls (with 21.339.194 pregnancies) were included in this review.Concerning maternal outcomes, delivery by caesarian section (CS) was more frequent among JIA women (in 4 out of 6 studies). Pre-eclampsia was referred in 3 out of 6 studies and a higher risk of vaginal bleeding and placenta previa in one additional study. No study found an increased risk for gestational diabetes or hypertension in pregnant women with JIA.Regarding fetal outcomes, 8 studies revealed significantly increased of pre-term birth (only in first births in one study) but one study didn’t show any increased risk. Two studies showed a higher risk of small gestational age (SGA) and in another 2, increased risk for low birth weight (LBW). No evidence of increased risk of major congenital malformations.Conclusion:This systematic review suggests an increased risk for pre-eclampsia, preterm birth, delivery by CS, SGA and LBW, among pregnant women with JIA. Conclusions should be carefully interpreted, giving the heterogeneity of studied populations regarding demography, disease type, disease activity, and prescribed medication.Disclosure of Interests:None declared

Runoff Model

Accurate monthly runoff estimation is crucial in water resources management, planning, and development, preventing and reducing water-related problems, such as flooding and droughts. This article evaluates the monthly hydrological rainfall-runoff model’s performance, the GR2M model, in Thailand’s southern basins. The GR2M model requires only two parameters: production store (X1) and groundwater exchange rate (X2). Moreover, no prior research has been reported on its application in this region. The 37 runoff stations, which are located in three sub-watersheds of Thailand’s southern region, namely; Thale Sap Songkhla, Peninsular-East Coast, and Peninsular-West Coast, were selected as study cases. The available monthly hydrological data of runoff, rainfall, air temperature from the Royal Irrigation Department (RID) and the Thai Meteorological Department (TMD) were collected and analyzed. The Thornthwaite method was utilized for the determination of evapotranspiration. The model’s performance was conducted using three statistical indices: Nash–Sutcliffe Efficiency (NSE), Correlation Coefficient (r), and Overall Index (OI). The model’s calibration results for 37 runoff stations gave the average NSE, r, and OI of 0.657, 0.825, and 0.757, respectively. Moreover, the NSE, r, and OI values for the model’s verification were 0.472, 0.750, and 0.639, respectively. Hence, the GR2M model was qualified and reliable to apply for determining monthly runoff variation in this region. The spatial distribution of production store (X1) and groundwater exchange rate (X2) values was conducted using the IDW method. It was susceptible to the X1, and X2 values of approximately more than 0.90, gave the higher model’s performance.
