Election of Water Resources Management Entity Using a Multi-Criteria Decision (MCD) Method in Salta Province (Argentine)

At present, the water resources are a strategic element each time more necessary and limited becoming a source of conflicts. For that, it is fundamental to create an independent and competent entity with good reputation and social acceptation. This entity must be able to obtain, store and process all data dispersed in different entities creating a network for these purposes. Finally, it must be able to organize different branches between the government and the final users. Using one of the wellknown Multicriteria Decision Methods(MCDM) with several realistic alternatives and several criteria identified in expert seminars in Salta and Madrid, we have obtained hopeful results and more recently new modifications introduced have generated better results

Diseño e Implementación de un firewall de nueva generación usando herramientas de código abierto para el Instituto Superior Tecnológico Libertad

El diseño del firewall de nueva generación (NGFW) en un ambiente de pruebas para la institución tiene como finalidad asegurar los recursos presentes en su red ante posibles ataques e intrusiones. Para conseguirlo, se analizó el estado de la infraestructura identificando los posibles riegos a los que esta estaba expuesta, se propuso un nuevo diseño de red debido a las deficiencias que presentaba el actual también, se identificó los activos a los cuales se pretendía asegurar y proteger ante posibles ataques. Para el diseño del NGFW, se empleó un servidor sobre el cual se virtualizó ambientes de pruebas utilizando herramientas open source como: pfsense, zentyal, proxmox, opnsense, estas fueron configuradas de manera que ayudan a controlar los accesos a los recursos de red y monitoreo del tráfico para identificar posibles comportamientos no deseados también se establecieron perfiles de navegación y reglas de filtrado de contenido. Los cambios ayudaron a mejorar el rendimiento de la red institucional obteniendo mejores tiempos de respuesta en la transmisión de datos, se pudo garantizar el acceso a recursos compartidos como impresoras, unidades de red, scanners a todo momento sin perjudicar la productividad del personal, hubo una mejora en los accesos a recursos en internet gracias a la optimización del uso del ancho de banda debido a las políticas y perfiles de navegación configuradas en el NGFW. Pese a la implementación de las soluciones de seguridad sean de pago o gratuitas, es necesario educar a los usuarios para que estén alertas y tomen precauciones para evitar ser víctimas de phishing, programas malignos y ransomware, los cuales son los principales causantes de brechas de seguridad.The design of the new generation firewall solution (NGFW) in a test environment developed for the institution aims to secure the resources present in its network against possible attacks and intrusions. To achieve this, the state of the technological infrastructure was analyzed, identifying the possible risks to which it was exposed, in this process a new network design was proposed due to the deficiencies of the current one, in addition to identifying the sensitive assets to be secured and protected against possible attacks. For the design of the NGFW, a server was used on which the test environments were virtualized using open-source tools such as: pfsense, zentyal, proxmox, opnsense, these were configured to help us control access to network resources and traffic monitoring to identify possible unwanted behavior, navigation profiles and content filtering rules were also established. These changes helped to improve the performance of the institutional network by obtaining better response times in data transmission, it was possible to guarantee access to shared resources such as printers, network drives, scanners always without affecting staff productivity, there was an improvement in access to Internet resources thanks to the optimization of bandwidth use due to the policies and browsing profiles configured in the NGFW. Despite the implementation of security solutions, whether paid or free, it is necessary to educate users to be alert and take precautions to avoid becoming victims of phishing, malware, ransomware, which are the main causes of security breaches

Copper, zinc, mercury and arsenic content in Micropogonias furnieri and Mugil platanus of the Montevideo coastal zone, Río de la Plata

Metals (Cu, Zn, Hg) and metalloid (As) concentrations were measured in Micropogonias furnieri and Mugil platanus caught in three areas along the Montevideo coastal zone during winter 2010, spring 2010 and 2011. Compared to previous studies conducted in the zone, both species showed higher (for Cu), similar (for Zn) or lower (for Hg) concentrations. The highest Hg values were found in the M. furnieri of Montevideo bay. There was no spatial variation in Cu, Zn, and As concentrations in muscle, likely due to the high mobility of both species. However, the Cu content in the liver of M. furnieri was higher in fish from the West zone. Cu, Zn and As found in the liver of M. platanus were much higher than in that of M. furnieri. A functional relationship between muscle levels of Zn and Hg and fish length of M. furnieri indicates bioaccumulation of these metals. According to the results, M. furnieri may be used as a temporal bioindicator for Hg, but not as a spatial bioindicator. Mercury levels were below the maximum safety level based on international standard values for human consumption.Foram estudadas as concentrações de metais (Cu, Zn, Hg) e metaloides (As) em exemplares de Micropogonias furnieri e Mugil platanus coletados em três locais ao longo da costa de Montevidéu (Uruguai) durante o inverno de 2010 e as primaveras de 2010 e 2011. Comparados com estudos prévios realizados nessas áreas, ambas as espécies apresentaram concentrações maiores (para Cu), similares (para Zn) ou menores (para Hg). Os valores mais elevados de Hg foram encontrados em M. furnieri da baía de Montevidéu. Não houve variação espacial na concentração dos elementos Cu, Zn, and As, provavelmente devido à alta mobilidade de ambas as espécies. No entanto, a concentração de Cu no fígado de M. furnieri foi maior nos peixes da área Oeste. Cu, Zn e As foram encontrados em M. platanus em valores mais elevados do que no fígado de M. furnieri. A relação funcional entre os níveis de Zn e Hg no músculo e o comprimento dos peixes em M. furnieri indica bioacumulação para estes metais. De acordo com os resultados, M. furnieri pode ser utilizado como bioindicador temporal para Hg, mas não como bioindicador espacial. Os níveis de Hg registrados estiveram abaixo do nível máximo de segurança com base nos valores do padrão internacional para o consumo humano

Understanding the Relationship between Predictors of Alcohol Consumption in Pregnancy: Towards Effective Prevention of FASD

Prenatal alcohol exposure can produce serious changes in neurodevelopment that last a lifetime, as well as a wide range of congenital abnormalities, and is the main non-hereditary, avoidable cause of intellectual disability in developed countries. It is therefore crucial to understand the determinants of alcohol consumption during pregnancy. This study is aimed at determining the factors that predict it, as well as the interactions between them. Methods: A cross-sectional study was carried out using a random sample of 426 pregnant women being treated at the outpatient clinic of a public university hospital in Seville (Spain), when they were in their twentieth week of pregnancy. A custom-designed questionnaire was used for data collection and applied in the course of an interview administered by trained health professionals. The data collected were analyzed using hierarchical regression, moderation analysis, and a structural equations model. Results: Alcohol consumption prior to pregnancy proved to be the most powerful predictor of alcohol intake during pregnancy. Other particularly significant predictors were the percentage of professionals who gave correct advice to the expectant mother—not to consume any alcohol during pregnancy—and perception of the risk from drinking wine during pregnancy. The number of pregnancies correlates positively with alcohol intake during pregnancy, while the expectant mother’s level of education correlates negatively. Conclusions: Identifying these predictive factors will allow the design of more effective fetal alcohol spectrum disorder (FASD) prevention strategies.Universidad de HuelvaPlan Andaluz de investigación, desarrollo e innovación (PAIDI

Pregnant Women’s Risk Perception of the Teratogenic Effects of Alcohol Consumption in Pregnancy

There is ample evidence of the teratogenic effects of prenatal alcohol exposure, with long-term consequences throughout the entire life cycle. Nevertheless, research on risk perception of alcohol consumption among pregnant women is scarce. In order to analyze risk perception of alcohol consumption during pregnancy, a cross-sectional study was conducted with a random sample of 426 pregnant women (in their 20th week of gestation) receiving care at the outpatient clinics of a public university hospital in the southern European city of Seville (Spain). Data were collected through structured face-to-face interviews conducted by trained health professionals using a customized questionnaire. Data analysis included structural equation modeling. Only 48.1% of the sample indicated that the sequelae from alcohol consumption during pregnancy were life-long. The structural equation model showed that a lower risk perception about beer and wine consumption, and a lower educational level, were related to more frequent alcohol consumption. Younger participants showed lower risk perception concerning beer consumption. Higher levels of education were related to a greater risk perception of beer. Healthcare institutions should articulate programs that facilitate health advice regarding alcohol consumption during pregnancy, particularly when providing care for women with low educational levels

Variability of nitrogen mineralization from organic matter in agricultural soils in the north of Colombia

Variation of Nitrogen mineralization (Nm) and its relationship to physicochemical factors in soils of an irrigation district in the North of Colombia was evaluated. Physicochemical parameters were measured in topsoil (0–30 cm) samples taken from 22 points in agricultural lands (10 in the dry season, 12 in the wet season). Nm was estimated from organic matter (OM) content. Soil parameters in the study area are suitable for crop development, although they present variations between the dry and wet season, where the soil pH varies of slightly acidic to neutral and the OM content decreases. Additionally, in the dry season there was a positive correlation with pH, OM and C/N ratio and, during wet season between OM, sand, clay and bulk density. In both seasons, a negative correlation between silt and Nm was common. Environmental and soil conditions in the study area are favourable for Nm because during the dry season the accumulation of OM is favoured. Understanding how physicochemical factors influence Nm is essential for agricultural activities and the development of sustainable ecosystem services

Relationship between Eating Habits, Physical Activity and Tobacco and Alcohol Use in Pregnant Women: Sociodemographic Inequalities

Pregnant women must maintain or acquire healthy habits during pregnancy to protect both their own health and their child’s. Such habits include an adequate eating pattern along with good adherence to the intake of certain supplements, practice of moderate physical activity and avoiding the consumption of toxic products such as tobacco and alcohol. The objective of this study is to assess the interrelation between such habits and their association with sociodemographic variables. To such end, a cross-sectional study was conducted with a representative sample of pregnant women who attended the scheduled morphology echography consultation at the 20th gestational week in their reference public hospital in the city of Seville (Spain). Results: Younger pregnant women and with lower educational levels are the ones that present the worst eating habits and the highest smoking rate. Pregnant women with lower educational levels are the least active. Non-smoking pregnant women present better eating habits than those who smoke. Pregnant women with lower educational levels are those who accumulate more unhealthy habits during pregnancy. This should be taken into account when planning the health care provided to pregnant women and in public health intersectoral policies

Monitoring of playa Caldera and coastal structures with unmanned aerial vehicles (UAV)

The monitoring of costal structures is required to verify that they are operating properly, to assess potential for functional and structural damage, and to correlate processes that are not contemplated in the original designs. Digital camera technology advances in combination with Unmanned Aerial Vehicles (UAV) can be used to obtain survey data using photogrammetric techniques in a precise and effective way. This approach yields high productivity in comparison with traditional methods, such as using total stations, and carries lower operational costs than LIDAR, conserving data quality. Correlation of physical processes and changes in interaction with natural and artificial costal structures is important due to information provided. These data can be use in future circumstances to anticipate damages and changes. The current study determined the effect on the principal breakwater at Caldera Port and beach, caused by a storm. Included herein are a brief description of the UAV photogrammetric methods, the study area, the data acquisition and the limitation of these techniques. Results of the study and concluding remarks have been included as well.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ingeniería::Instituto Investigaciones en Ingeniería (INII
