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
Tariffs and industrial location in Ecuador
The theoretical literature has reached no consensus on whether international trade liberalization increases concentration of economic activities within a given country or whether dispersion occurs as the country progressively opens to trade. This paper contributes to this literature by analyzing the experience of Ecuador in the first decade of the 21st century. This country is an interesting case study because it has two economic centers of similar size (Quito, the capital, and Guayaquil) which is different from other Latin American countries. At the same time, the trade liberalization policies followed a similar path of those in other Latin American countries that dismantled the import substitution regime. Our econometric results based on a sample of 20 provinces and 20 industrial sectors in two periods of time, 2000 and 2010, suggest that trade policy did not substantially modify the patterns of location of manufacturing in Ecuador during this period. If anything, it only reinforced, a little, the concentration of economic activities in Quito

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
