This paper examines the different impressions and perspectives related to the implementation of electromobility in log transportation via trucks with a load capacity of up to 45 tons in the forestry sector of the eighth and sixteenth regions of Chile. The objective of this work is to establish the critical variables identified and perceived by key stakeholders of the forestry industry the correct implementation of high tonnage electric trucks. To this effect, a qualitative methodological study with a non-experimental design is proposed, which is based on semi-structured interviews conducted with stakeholders of the forestry sector of the study area. A convenience sample is employed, which was applied to four businessmen in the sector, three executives from the main forestry companies, and two truck distributor representatives. The data show that there is currently little knowledge due to the lack of specific projects and platforms for disseminating information that consider this technology in the field, but, on the contrary, they show a willingness to implement pilot plans aiming for the perceived economic sustainability of electromobility. A concentration of critical aspects is evidenced, which must be addressed in order to implement electromobility in forest transport, and which, given handling by public-private work, would enable the sector and the country to obtain the economic and environmental benefits of this technology.

Digital Transformation: Opportunity or Threat to Employability?
(2021)
VALDÉS GONZÁLEZ, HÉCTOR MOISÉS
;

;
Rojas Romero, Rolando
This paper presents a critical analysis of the Digital Transformation’s (DT) effects on employability within organizations in Chile, providing an action reference framework for competitiveness in the field. To achieve this, a qualitative approach to the opinions of a convenience sample of executives and leaders was employed, based on semi-structured interviews, to understand how to address this type of transformation. The analysis indicates that, having long-term policies for the development of new skills in their collaborators is a critical success factor. These policies are summarized in three stages, through a reference framework for the generation of specific actions in pursuit of the development of a successful DT process. DT fosters a cultural change in the entities to generate capacities that allow them to anticipate the evolution of the market and adapt quickly to it, for which it is fundamental to promote the training of new technical and behavioral skills in collaborators, in addition to encouraging them to self-train.

In Chile, as in many other areas of the world, water supplies have been poorly managed and water availability is decreasing. In order to manage water resources more sustainably and equitably, it is necessary to understand and predict their supply and use considering the characteristics of a particular zone. This study aimed to develop a conceptual model for water management in the Libertador Bernardo O’Higgins Region in Chile. The model considers the water needs of industries with production activities, human consumption, and the ecological flow of each sub-basin in the area. The results show that the proposed model contributes to the understanding of the critical variables, their agents, and the interaction between the hydric demands, which enables the prioritization of human consumption and the ecological flow. Furthermore, the cross-analysis between the offer and demand indicates that current and predicted consumption levels will only be sustainable up to the year 2031. The findings may be of use to decision-makers seeking to improve water management plans in this area and elsewhere, and to others interested in modeling water management in different areas.

Este trabajo analiza las principales brechas que influyen en las PyMEs TI (pequeñas y medianas empresas de tecnología de la información) con metodología tradicional, al iniciar la implementación de metodologías ágiles para la gestión de proyectos. El objetivo de esta investigación es determinar las principales brechas existentes antes de implementar metodologías ágiles en una PyME TI con metodología tradicional para la gestión de proyectos. Para lograrlo se propone una aproximación cualitativa a las opiniones de tres gerentes, dos ingenieros de proyecto y seis analistas programadores de la empresa, basada en entrevistas semiestructuradas, considerando una muestra por conveniencia, para entender las dificultades existentes en la empresa de estudio, contrastando dicha realidad mediante encuestas dirigidas a 29 profesionales de áreas TI de otras organizaciones. Los resultados del análisis revelan que las principales brechas para la implementación de metodologías ágiles en la PyME son la cultura organizacional en desacuerdo con la agilidad, la falta de compromiso de la gerencia y la resistencia al cambio. Se concluye que la propuesta resulta ser efectiva para conocer las principales brechas a resolver antes de comenzar la implementación de una metodología ágil en una PyME TI, permitiendo alinear a la organización con la agilidad.

<jats:p>Las Simulaciones de Equilibrio Líquido Vapor (VLE) son ampliamente utilizadas dado su impacto en el escalamiento, diseño y extrapolación de diferentes operaciones unitarias. Sin embargo, dado considerable factores, es casi imposible experimentalmente estudiar cada uno de los sistemas de VLE. La simulación de VLE puede ser desarrollada utilizando representaciones que son fuertemente dependientes de la naturaleza e interacción de los compuestos que conforman la mezcla. Un modelo que ayude en la predicción de esas interacciones facilitará el proceso de simulación. Una Red Neuronal Gris (GNM) fue creada como un predictor de parámetros de interacción binaria, los que son estimados utilizando variables de estado e información de componentes puros. Esta información fue utilizada para predecir el comportamiento de VLE en mezclas y rangos no utilizados en la formulación matemática. Las capacidades predictivas del GNM (incluida la dependencia de temperatura) mostraron errores menores al 5% y al 20% para mezclas consideradas y no consideradas en los datos de entrenamiento, respectivamente.</jats:p>

<jats:p>Despite technological advancements in mining, Chile lacks comprehensive risk management models for tailings storage facilities (TSFs), which hinders the prevention and mitigation of structural and environmental risks. This study aims to develop an integrated risk management model for TSFs in Chile, combining geological and mining engineering with an updated regulatory framework to enhance safety and reduce environmental impacts. The research adopts a mixed-methods approach. Qualitatively, it draws on 10 semi-structured interviews with engineers, geologists, academics, and professionals from the Chilean mining industry, selected through purposive sampling, to explore how and why the current risk management model should be improved. Quantitatively, it analyzes data from 303 surveys assessing the existing regulatory framework, a proposed new regulatory decree for Chile, and key variables to be considered in TSF risk management. The results present a new model that integrates geochemical and geotechnical characterization, process variables, in situ sensors, remote sensing, and artificial intelligence to generate dynamic risk indicators and early warning systems throughout the life cycle of the facility, including closure and liability valuation. Its multiscale design, adaptable to seismic and hydrogeological conditions and suitable for small- and medium-scale mining, overcomes existing static and fragmented approaches, enabling more effective decision-making with a focus on environmental and community safety. The study concludes that the model provides a robust and coherent tool for TSF risk management by integrating technical expertise, the current regulatory framework, and the management of key variables that enhance the ability to anticipate and mitigate structural and environmental risks.</jats:p>
