Tratamiento de la informacion de violencia de género. Con aportaciones de la inteligencia artificial / Treatment of the information on gender-based violence. With contributions from artificial intelligence

Introducción/objetivos la violencia contra la mujer sigue siendo un grave problema social y de salud a pesar de las medidas puestas en marcha en los últimos años. La exploración de las víctimas por el médico forense en los juzgados es de gran interés puesto que recibe información relacionada no solo con la agresión, sino también de su entorno social, familiar y económico. El objetivo es utilizar dicha información para identificar grupos de riesgo y mejorar/obtener las medidas necesarias. Material y métodos en este trabajo, el forense ha recogido, durante 8 años, una toma abundante de datos sobre las víctimas exploradas en L’Hospitalet de Llobregat. La muestra incluye 1.622 casos de mujeres víctimas de violencia de género. Se realiza un estudio descriptivo poblacional y de las lesiones. Resultados se exponen las principales variables estudiadas tanto socioeconómicas como referentes a la agresión en sí. Se trabaja también con base en la reentrada de las víctimas o repetición de las agresiones (revictimización), que son el 10,9% de la muestra. Finalmente, se presentan los resultados obtenidos tras aplicar técnicas de inteligencia artificial, en este caso, árboles de clasificación CaRT. Conclusiones con los resultados obtenidos concluimos que el tratamiento de la información recogida y sistematizada de la intervención médico-forense permite una mejor comprensión de la violencia sobre la mujer, de la que podemos extraer sugerencias sobre la adopción de medidas de atención y soporte a las víctimas y a los colectivos más vulnerables, así como sobre los recursos administrativos y la optimización de programas de prevención.

Introduction/objectives Violence against women is still a serious social and health problem, despite the measures implemented in recent years. The examination of the victims by the forensic doctor in the courts is of great interest since it provides information related not only to the aggression, but also to their social, family and economic environment. The objective is to use this information to identify groups at risk and improve/implement the necessary measures. Material and methods In this work, the forensic has collected, for eight years, abundant data on the victims examined in L'Hospitalet de Llobregat. The sample includes 1,622 cases of women who have been victims of gender violence. A descriptive study of the population and of the lesions has been carried out. Results The paper presents the main variables studied, both socioeconomic and referring to the aggression itself. This study also analyzes the reentry of the victims, the repetition of aggressions (revictimization), which are 10.9% of the sample. Finally, the results obtained after applying artificial intelligence techniques -in this case, CaRT classification trees- are presented. Conclusions With the results obtained, we conclude that the treatment of the information collected and systematized from the medical-forensic intervention allows a better understanding of Violence Against Women, from which we can extract suggestions on the adoption of care and support measures for the victims and the most vulnerable groups, as well as administrative resources and the optimization of prevention programs.

Evaluation of microplastic release caused by textile washing processes of synthetic fabrics.

A new and more alarming source of marine contamination has been recently identified in micro and nanosized plastic fragments. Microplastics are difficult to see with the naked eye and to biodegrade in marine environment, representing a problem since they can be ingested by plankton or other marine organisms, potentially entering the food web. An important source of microplastics appears to be through sewage contaminated by synthetic fibres from washing clothes. Since this phenomenon still lacks of a comprehensive analysis, the objective of this contribution was to investigate the role of washing processes of synthetic textiles on microplastic release. In particular, an analytical protocol was set up, based on the filtration of the washing water of synthetic fabrics and on the analysis of the filters by scanning electron microscopy. The quantification of the microfibre shedding from three different synthetic fabric types, woven polyester, knitted polyester, and woven polypropylene, during washing trials simulating domestic conditions, was achieved and statistically analysed. The highest release of microplastics was recorded for the wash of woven polyester and this phenomenon was correlated to the fabric characteristics. Moreover, the extent of microfibre release from woven polyester fabrics due to different detergents, washing parameters and industrial washes was evaluated. The number of microfibres released from a typical 5 kg wash load of polyester fabrics was estimated to be over 6,000,000 depending on the type of detergent used. The usage of a softener during washes reduces the number of microfibres released of more than 35%. The amount and size of the released microfibres confirm that they could not be totally retained by wastewater treatments plants, and potentially affect the aquatic environment.
