Digital Transformation: Opportunity or Threat to Employability?

2021 , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Lorenzo Reyes-Bozo , 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.

Vapor-Liquid equilibria modeling using gray-box neural networks as binary interaction parameters predictor

2017 , Eduardo Andres Vyhmeister Bastidas , Jonathan Rodríguez-Pino , Lorenzo Reyes-Bozo , Rosa Galleguillos-Pozo , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Roman Rodríguez-Maecker

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.

Metodologías ágiles: un análisis de los desafíos organizacionales para su implementación

2021 , Fernando Flores-Cerna , Víctor-Manuel Sanhueza-Salazar , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Lorenzo Reyes-Bozo

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.

The Water Management Impacts of Large-Scale Mining Operations: A Social and Environmental Perspective

2024 , Katherine Arenas-Collao , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Lorenzo Reyes-Bozo , José Luis Salazar

This study investigates water consumption in two areas with limited water resources—the Salar de Atacama and Salar de Atacama-Vertiente Pacifico basins in Chile’s Antofagasta Region—with the aim of developing strategies that incorporate social and environmental aspects into water management. A qualitative approach was employed that involved a focus group with twelve water management representatives and surveys of the general population (468 responses). Additionally, the current state of water rights in the two basins was examined and the feasibility of the proposed strategies was assessed. The findings reveal that the mining industry’s development approach is mostly viewed as negative, mainly due to inadequate community engagement, confidential consumption data, and limited government oversight. The quantitative findings indicate that 53.8% of respondents see the main obstacle as the lack of a solution satisfying both parties. Additionally, 35.3%, 24.4%, and 22.4% believe transparency, objective information provision, and detailed resource usage disclosure by mining companies would help. Adopting a comprehensive water stewardship approach that considers social and environmental factors would enable a novel contribution to a more effective and sustainable water resource management system in northern Chile, mitigating communities’ negative perceptions of the industry and facilitating the integration of communities and involved agents. Therefore, improved management and transparent collaboration among stakeholders are essential for responsible water resource use in mining.

Blockchain in Supermarkets: Mitigating the Problem of Organic Waste Generation

2021 , Marcos Egatz Wozniak , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Lorenzo Reyes-bozo

This work presents a proposal for a solution to the specific problem of organic waste generated by supermarkets and understood as t merchandise of organic and perishable composition that could not be marketed during its validity period. The goal of this research is to propose a solution based on Blockchain technology in Chile, which would allow an immutable, decentralized, and validated transaction record to be kept. Such a record would enable supermarkets to trace the life cycle of those products that make up organic and perishable merchandise in a transparent, reliable, and scalable way. To this end, the problem is modeled using the Blockchain Hyperledger Fabric platform (an open-source platform started by the Linux Foundation), which is fed with relevant information and data on the status of a representative set of organic merchandise products. At the same time, a qualitative approach is proposed to gather the opinions of executives and logistics operators through semi-structured interviews, and considering a convenience sample. With a sample of 6 executives, it is understood how the proposal is perceived and its applicability in supermarkets and distributors. The data show that both obtaining information and making decisions about it are achieved in a distributed and collaborative way, allowing for reliable and agile traceability, thereby mitigating the low quality of the information provided by the actors that make up the supply chain. This service is perceived as desirable by both customers and operators.  The model enables not only horizontal communications between suppliers, distributors, and consumers, but also vertical ones, and thus, ultimately, makes the company's income statement more efficient.

A Conceptual Model Considering Multiple Agents for Water Management

2022 , BENJAMÍN ANTONIO RIVADENEIRA TASSARA , VALDÉS GONZÁLEZ, HÉCTOR MOISÉS , Carlos Fúnez-Guerra , Lorenzo Reyes-Bozo

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.
