    Parameterization proposal to determine the feasibility of geographic areas for the green hydrogen industry under socio-environmental and technical constraints in Chile
    (2024) San Martin, Marco; Poch, Paola; Carmona, Roberto; Rodriguez, Pablo; Rodriguez, Angel; Serafini, Daniel; Garrido, Rene; Mena, Marcelo; Valdes, Javier; Masip, Yunesky
    Chile, abundant in solar and wind energy resources, presents significant potential for the production of green hydrogen, a promising renewable energy vector. However, realizing this potential requires an understanding of the most suitable locations for the installation of green hydrogen industries. This study proposes a quantitative methodology that identifies and ranks potential public lands for industrial use, based on a range of technical parameters (such as solar and wind availability) and socio-environmental considerations (including land use restrictions and population density). The results reveal optimal locations that can facilitate informed, sustainable decision-making for large-scale green hydrogen implementation in Chile. While this methodology does not replace project specific technical or environmental impact studies, it provides a flexible, general classification to guide initial site selection. Notably, this approach can be applied to other regions worldwide with abundant solar and wind resources, such as Australia and Northern Africa,

    Relación médico-paciente en la Pontificia Universidad Católica de Chile: evaluación de una escala de medición
    (SOC MEDICA SANTIAGO, 2012) Rodriguez, Angel; Mardones, Francisco; Villarroel, Luis
    Background: Beneficence, respecting autonomy of patients to make their own decisions, is crucial for good physician-patient relations (PPR), a leading objective in health care. Aim: To validate a previously designed scale to assess PPR in Chile. Material and Methods: A scale with 55 questions grouped in six dimensions, was applied to a convenience sample of 146 individuals, composed by physicians, patients and medical students, at the school of medicine from the Pontificia Universidad Catolica de Chile (PUC). Internal consistency (Alpha of Cronbach) of answers was analyzed. The existence of correlations between answers that may justify the application of a factorial analysis was assessed using Bartlett and Kaiser-Meyer-Olkin (KMO) tests. Factorial analysis was used to identify specific dimensions and reduce the number of questions. Results: Factorial analysis performed in 125 subjects with complete answers allowed to reduce the scale to 28 questions, grouped in six dimensions. Cronbach alpha value was 0.78. Bartlett test was highly significant (p <0.0001), and KMO score was 0.784, considered as meritorious. Conclusions: The validated scale will allow the performance of new studies among physicians and patients, to assess and compare their respective scores. (Rev Med Chile 2012; 140: 176-185).
