Dementia produces a loss of independence to carry out the activities of daily life. The great demand for care that these people need usually falls on the family through informal care. This study aims to analyse the burden showed by the informal caregiver of a person with dementia. In addition, we analyse whether this burden present in informal caregivers could be related to abusive behaviour. We also study the relationship between the stage of the disease, the appearance of behavioural disorders and the level of burden in the caregiver using the Scales of Zarit, CASE and FAST. The data showed that 45.50 per cent of caregivers have light burden or burden. After the research, it was identified that the presence of behavioural disorders in patients with dementia showed a correlation with the increase in both the main caregiver burden and abuse. An increase in the level of burden is followed by an increase in the level of abuse (r = 0.844; p = 0.000). Furthermore, we analysed several conditions that could have a correlation with this burden and abuse. It was found that burden in the caregiver could be linked with the presence of behavioural disorders, like aggression (r = 0.577; p = 0.008) and irritability (r = 0.600; p = 0.005) at the moderate stage of the disease. On the other hand, there is a positive correlation between the probability that people with dementia suffer abuse in the moderate stage of the disease and the presence of aggression (r = 0.732; p = 0.000), lack of inhibition (r = 0.571; p = 0.009) and irritability (r = 0.827; p = 0.000). Taking this data into account, burden and abuse seem to be linked to the presence of behavioural disorders in patients with dementia in the moderate stage.

The quality of teacher education plays a key role in equipping students with the skills they need and it is important in avoiding learning inequalities. To bridge the digital divide and ensure that all students have equal access to technology and digital resources as well as advanced teaching–learning processes using digital tools, it is crucial to analyse the current state of teacher education in order to identify the key issues. The sample in this research consisted of 325 master of education students and in-service teachers studying at various universities (in Spain, Cyprus, and México) in the 2022–2023 academic year who filled out a questionnaire partly based on DigComEdu and this was expanded with questions relating to other digital and educational aspects. The findings reveal that there is potential for enhancement in many areas. Despite teachers having technical training associated with their profession, they lack the necessary training to overcome inequalities or digital gaps. Moreover, it is striking that those who are already working as teachers are the most pessimistic about aspects such as the use of digital resources, perhaps because of the difficulties they face in their daily work.

RESUMENLas soft-skills o competencias transversales se consideran imprescindibles hoy en día para la formación en cualquier campo de conocimiento. Sin embargo, en los servicios de orientación profesional para universitarios todavía no se han incorporado de forma general. El objetivo de la investigación es conocer cómo influye el recibir orientación profesional por competencias transversales en el nivel de empleabilidad de los universitarios-egresados y comprobar si existen diferencias significativas según sexo, edad o situación laboral.Se utiliza un diseño cuasiexperimental pretest-postest con grupo control-experimental. Se lleva a cabo una intervención de orientación por competencias, La muestra es de 748 universitarios-egresados que solicitan orientación profesional y participan en programas subvencionados por la Unión Europea dentro de los programas de los Agentes Sociales de Aragón. Obtenemos la información a través de cuestionarios, entrevistas y de grupos de discusión elaborados (ad hoc). Los datos cuantitativos son analizados con el programa estadístico SPSS y los datos cualitativos son analizados a través de categorización predefinidas y emergentes por segmentos o unidades de análisis y textos transcritos con el software Nvivo.Se halla que la orientación profesional por competencias mejora el nivel de empleabilidad de los universitarios. Recibir orientación profesional por competencias contribuye positivamente a la mejora del nivel de empleabilidad de los universitarios en general y al desarrollo de las competencias transversales y del manejo de los recursos y las herramientas de un modo particular. Existe una clara correlación entre los universitarios-egresados que reciben orientación profesional por competencias y una coyuntura laboral satisfactoria en los mismos.ABSTRACT Soft skills or transversal competences are considered essential for training in any field of knowledge. However, professional guidance services for university students have not yet been incorporated. The aim of the research is to know how professional orientation by transversal competences influences the level of employability of university-graduates and to check if there are significant differences according to sex, age or employment situation.For the research, a quasi-experimental pretest-posttest design with a control-experimental group was used, as well as a competency orientation intervention. The sample was compound of 748 university-graduates who request professional guidance and were enrolled in programs subsidized by the European Union within the programs of the Social Agents of Aragon. Information was obtained through questionnaires, interviews and discussion groups. Quantitative data are analyzed with SPSS statistical program and qualitative data are analyzed through predefined and emerging categorization by segments or units of analysis and transcribed texts using Nvivo software.It is found that professional orientation by competences improves the employability level of the university students. Receiving professional guidance by competences contributes positively to the improvement of the employability level of university students in general and to the development of transversal skills and the management of resources and tools. There is a clear correlation between the university-graduates who receive professional guidance by competencies and a satisfactory working conjuncture in themselves.

This study evaluates the feasibility and effectiveness of the Life Cycle Assessment (LCA) methodology. Two widely used products with the same functionality but different designs and production processes were selected for comparative analysis. SimaPro 9.6.0 software was used for the calculations and LCA of both assemblies. The analysis covered all phases of the life cycle, taking into account factors such as energy, materials and water consumption. The results allowed a comparison of the environmental impacts of the two assemblies, identifying the life cycle phases with the highest impact and the most relevant impact categories. The analysis revealed that the metal trolley exhibited a 40% higher environmental impact during production compared to the polypropylene trolley, primarily due to the material extraction and processing phases. Additionally, the polypropylene trolley showed higher long-term impacts in landfill scenarios due to carcinogenic substance emissions. These findings highlight the significance of design and material selection in reducing environmental impacts. Applying the LCA methodology to the two mechanical assemblies allowed us to identify opportunities for improvement in the design and manufacturing processes, with the aim of reducing the environmental impact and increasing the competitiveness of the products. By considering the full life cycle of a product from the early design phases, more sustainable design and manufacturing decisions can be made, and by using this analysis, companies can develop more sustainable products and reduce costs.

Milling machines remain relevant in modern manufacturing, with tool optimization being crucial for cost reduction. Inserts for compound cutting tools can reduce the cost of operations by optimizing their lifespan. This study analyzes the flank wear of cutting tools in milling machines, with an emphasis on evaluating different approaches to predict their lifespan. It compares three distinct modeling approaches for predicting tool lifespan using algorithms: traditional ensemble methods (Random Forest, Gradient Boosting) and a deep learning-based LSTM network. Each model is evaluated independently, and this comparative analysis aims to determine which modeling strategy best captures the intricate interactions between various process variables affecting tool wear. This method ensures greater efficiency and accuracy than conventional techniques, providing a scalable, resource-efficient solution for reliable and insightful tool wear predictions. The results obtained from the dataset of an insert tool can be extrapolated to other milling inserts and demonstrate the progression of tool wear over time under varying cutting parameters, providing critical insights for optimizing milling operations. The integration of uncertainty awareness in the predictive outputs is a unique feature of this research and enhances decision-making for smarter manufacturing. This proactive approach enhances operational efficiency and reduces overall production costs. Furthermore, the data-driven, AI-centric methodology developed in this study offers a transferable approach that can be adapted to other machining processes, advancing state-of-the-art tool wear prediction.
