Authors: Oliveira Janiel Lopes de , Fehr Manfred 
Published: April 2021

RESUMOA erosão do solo é um indicador de degradação no meio físico, situação que causa prejuízo econômico e ambiental. Diante dessa problemática, essa pesquisa teve como objetivo analisar a vulnerabilidade erosiva para a bacia hidrográfica do ribeirão Conquistinha no Oeste de Minas Gerais. Foi aplicada a metodologia de análise multicritério de acordo com propostas da literatura. Em primeiro momento, realizou-se a confecção do banco de dados com as unidades de análise (componentes litológicos, aspectos geomorfológicos, solos, influência climática (chuva), vegetação nativa com cobertura predominante), seguido da identificação dos componentes formadores de cada unidade e a atribuição dos valores de vulnerabilidade à cada componente. Posteriormente foi realizado o cruzamento entre os valores individuais dos componentes para obtenção dos pesos representativos à cada unidade de análise. Em seguida, realizou-se o cruzamento entre os pesos obtidos para as unidades de análise, tendo como resultando a vulnerabilidade erosiva para a bacia hidrográfica. Os resultados são: alta vulnerabilidade erosiva (23.43%), média vulnerabilidade erosiva (27.72%), baixa vulnerabilidade erosiva (31.50%), muito baixa vulnerabilidade erosiva (17.34%).Palavras – chave: Erosão do solo; Unidades de análise; Análise multicritério. Analysis of the Erosive Vulnerability of the Watershed of the Conquistinha Stream in the West of Minas Gerais, Brazil A B S T R A C TSoil erosion is an indicator of degradation in the physical environment, which causes economic and environmental damage. Given this problem, this research aimed to analyze the erosive vulnerability to the Conquistinha stream watershed in West of Minas Gerais. The methodology of multicriteria analysis, was applied according to literature proposals. In the first stage, the database was prepared with the units of analysis (lithologic components, geomorphological aspects, soils, climatic influence (rainfall), native vegetation with predominant cover), followed by the identification of the formation components of each unit and the attribution of vulnerability values to each component. Subsequently, the individual component values were cross-checked to obtain representative weights for each unit of analysis. Then, the weights obtained for the analysis units were crossed, resulting in erosive vulnerability to the river basin. The results are: high erosive vulnerability (23.43%), medium erosive vulnerability (27.72%), low erosive vulnerability (31.50%), very low erosive vulnerability (17.34%).Keywords: Soil erosion; Analysis units; Multicriteria analysis.

A manutenção da qualidade ambiental depende de intrínsecas relações entre os compartimentos ambientais. Assim, a manutenção de espaços verdes preservados e um manejo adequado do solo pode contribuir com a qualidade de vida da população. Sendo assim, o estudo avaliou a heterogeneidade espacial horizontal e vertical dos atributos dos solos do Parque Natural Chico Mendes, sob à ótica da importância dos parques urbanos para manutenção da qualidade ambiental e conservação dos solos. Para tanto, foram analisadas três zonas do parque com distintas fitofisionomias, sendo denominadas zona de mata conservada (ZMC); zona de mata (ZM) e zona de eucalipto (ZE). As análises físico-químicas foram realizadas nas profundidades de 0-20 cm, 20-40 cm e 40-60 cm, segundo as metodologias propostas pelo Instituto Agronômico de Campinas (IAC) e EMBRAPA. A espacialização dos dados foi realizada no software ArcGis 10.4.1 pelo método Inverso do Quadrado da Distância (IQD). Os resultados demonstraram a heterogeneidade espacial dos atributos químicos do solo nas diferentes fitofisionomias do parque, revelando que mesmo as áreas com pequenas extensões podem apresentar significativa diferenciação de atributos físico-químicos do solo, corroborando com a importância em se obter um manejo adequado do solo visando a manutenção da qualidade ambiental. Horizontal and Vertical Spatial Variability Analysis of Soil Attributes and their Relevance to Natural Park Chico Mendes, SP, Brazil A B S T R A C TMaintenance of environmental quality depends on intrinsic relationships between environmental compartments. Thus, the maintenance of preserved green spaces and proper soil management can contribute to quality of life of the population. Therefore, in this study was evaluated a spatial horizontal and vertical heterogeneity of the soil elements of the Natural Park Chico Mendes, from the perspective of the importance of urban parks for maintaining environmental quality and soil conservation. For this, three zones of the park with distinct phytophysiognomies were analysed, being conserved forest zone (ZMC); zone of forest (ZM) and zone of eucalyptus (ZE). The physicochemical analyses were extracted in depths 0-20 cm, 20-40 cm and 40-60 cm, according to the methodologies of the Agronomic Institute of Campinas (IAC) and EMBRAPA. The data spatialization was performed in the software ArcGis by the Inverse Distance Weighting (IDW) method. The results demonstrated the spatial heterogeneity of soil chemical attributes in different vegetation types of the park revealing that even areas with small extensions can show significant differentiation physico-chemical attributes, corroborating the importance of obtaining an appropriate soil management for the maintenance of environmental quality.Keywords: urban parks, soil management, spatial analysis, principal component analysis.
Imaginación y memorias de lo translocal de niñas y niños migrantes centroamericanos en tránsito por México
Authors: Reyes Gutiérrez Dulce Rocio 
Published: April 2021

En este artículo se analiza cómo las niñas y niños migrantes centroamericanos construyen lo translocal en su realidad, haciendo uso de la imaginación y la memoria, en un contexto transnacional y contingente como el que experimentan en su proceso de movilidad. Se delinea un argumento que privilegia la voz de las infancias, sus memorias y proyecciones, y examina los medios comunicativos, las redes sociales y familiares, a través de las cuales se va configurando su imaginación. Finalmente, se realiza una aproximación analítica que ve a esas construcciones subjetivas-objetivas como una forma de resistencia ante las condiciones de vulnerabilidad y violencia que enfrentan en el tránsito.
#LadyFrijoles: señalamiento, discriminación y estigma de migrantes centroamericanos a través de redes sociales en México
Authors: Pérez Díaz Marisol , Aguilar Pérez Mirza 
Published: April 2021

Atribuir connotaciones negativas a un grupo social desde los medios de comunicación y las redes sociales produce narrativas constructoras de identidades marginadas con una fuerte carga estigmatizante. La presente investigación se centra en las narrativas discriminatorias que realizan en las redes sociales sobre los migrantes centroamericanos y contribuye a los estudios que han puesto énfasis al respecto. El objeto de estudio es analizar las representaciones y las narrativas que surgieron a partir del caso conocido como “Lady Frijoles”, para pensar las lógicas de racismo y discriminación en redes sociales. Trabajamos a partir de un análisis cualitativo, buscando comentarios y representaciones compartidas vía Facebook y Twitter tras la aparición del video que un medio de comunicación compartió como un reportaje. Además, utilizamos el software AGEI para realizar un mapeo de las palabras más recurrentes de ese caso y crear una base de datos sobre los tweets. Los resultados apuntan a la necesidad de analizar las expresiones vertidas en las redes sociales para visibilizar la discriminación cotidiana sobre un fenómeno específico, que en este caso es la migración irregular de origen centroamericano en tránsito por México. Estas expresiones se dan bajo algunas condiciones que las permiten como el anonimato, lo instantáneo del mensaje y la facilidad de reproducción.

Published: April 2021

Background: We aim at presenting a clinical case of a 37-year-old patient, who has been a nun for several years and at the moment can no longer adapt to the environment in which she lives and to the requirements of everyday life. The perspective of this analysis is both a psychiatric one, explaining the diagnosis of Axis II of Histrionic Immature Personality Disorder, but also the overlap with dissociative conversion disorder, and explanatory from a psychodynamic perspective, by addressing the regression issues and the presence of the Oedipus Complex.
Histrionic Immature Personality Disorder and its overlap with Dissociative/Conversion Disorder are conditions with negative effects in terms of adaptation to the social environment and assuming professional responsibilities. Also, the particularities in the sphere of immaturity make it difficult to relate to those around.
Method: Hospitalization, psychiatric interview, psychodynamic interview, psychological tests - CAQ Personality Questionnaire and the Szondi Test, psychodynamic interpretations.
Results: The results highlight aspects of an immature premorbid personality, characterized by a high degree of sensitivity. Currently, the patient's ego is fragile and cannot adapt to the emotional meanings in the environment in which she lives, which leads to functional crises and manifestations such as dissociative fugue.
Conclusions: Dissociative manifestations are associated with immaturity and reduced ability to adapt to professional requirements. On a personal level, the same immaturity leads to the denial of one's sexuality and projection.

Published: April 2021

The stem borer (Ostrinia furnacalis Guenee) is one of the main pests of corn. The yield loss due to this pest attack reaches 20-80%. These pests are generally controlled chemically, causing various negative effects from the results of control, therefore environmentally friendly control techniques are needed, such as the use of bio-compost and bio-LOF. Bio-compost is compost combined with a consortium of bacteria Serratia marcecens, Bacillus thuringiensis and Pseudomonas fluorescens. Bio-LOF is a liquid organic fertilizer that is processed using cow feces, cow urine, Glicerida leaves and coconut husk. The research objective is to determine the effectiveness of bio-compost with several concentrations of bio-LOF to control stem borer pests in sweet corn. The research was conducted at experimental land of Payakumbuh Agricultural Polytechnic from January to June 2020. This study used a factorial completely randomized design (4x3) with 3 replications. Factor K, namely K1; Tithonia bio-compost, K2; Hay bio-compost. K3; Manure bio-compost. K4: without bio-compost. Factor D are: D1; Bio-LOF concentration 30%, D2; Bio-LOF 20%. D3: without Bio-LOF. The data obtained were analyzed for variance using a statistical program of 8.0, then continued with the dancun test α 5%. The results showed that the three types of bio-compost combined with bio-LOF could reduce the percentage of O. furnacalis pest attack on the stems and tips of sweet corn cobs. There were 5 treatment combinations with very effective criteria for coefficient of relatively control (CRC), namely. Tithonia bio-compost, Bio-LOF 30%, Hay bio-compost, bio-LOF 30%, chicken feces bio-compost, bio-LOF 30%, Straw bio-compost, Bio-LOF 20%, Without bio-compost, Bio-LOF 30%. The concentration of bio-LOF sprayed on the stems and leaves affects the effectiveness of the control where the 30% bio-LOF concentration had the very effective criteria of control, while the 20% concentration had the effective criteria of control.

Published: April 2021

Introduction: Hepatitis C is a chronic infection caused by hepatitis c virus - a blood borne virus. Therefore, the infection occurs through exposure to small quantities of blood. It has been estimated by World Health Organization (WHO) to have affected 71 million people worldwide. This infection costs individual, groups and government a lot because no vaccine has been gotten yet for the treatment. This disease is likely to continue to affect more people because it’s long asymptotic phase which makes its early detection not feasible.Material and Methods: In this study, we have presented machine learning models to automatically classify the diagnosis test of hepatitis and also ranked the test features in order to know how they contribute to the classification which help in decision making process by the health care industry. The synthetic minority oversampling technique (SMOTE) was used to solve the problem of imbalance dataset.Results: The models were evaluated based on metrics such as Matthews correlation coefficient, F-measure, Precision-Recall curve and Receiver Operating Characteristic Area Under Curve. We found that using SMOTE techniques helped raise performance of the predictive models. Also, random forest (RF) had the best performance based on Matthews correlation coefficient (0.99), F-measure (0.99), Precision-Recall curve (1.00) and Receiver Operating Characteristic Area Under Curve (0.99).Conclusion: This discovery has the potential to impact on clinical practice, when health workers aim at classifying diagnosis result of disease at its early stage.
