Este trabajo presenta el desarrollo de un sistema que permitirá al personal del servicio médico planificar, controlar, ejecutar, coordinar, y evaluar el manejo de la información médico-asistencial referente a las consultas médicas, el uso de los servicios de salud otorgados por instituciones externas y el programa de actividades orientadas al cuidado de la salud. En las estrategias que se han considerado dentro de la arquitectura del sistema es dotarlo de un mecanismo que le permita “aprender” y generar una base de datos de conocimiento como resultado de los registros y diagnósticos médicos. Además, el sistema apoyará la tutoría integral ofreciendo una herramienta de información para el docente sobre el estado de salud de los alumnos.

In this work, the ability of a series of imidazolium-based ionic liquids (ILs) to depolymerize Kraft lignin through acid hydrolysis was evaluated. ILs featuring two-, four-, and six-carbon alkyl chains combined with [Cl−], [BF4−] and [CH3COOH−] anions were studied to determine the influence of cation and anion structure. The twelve ILs were synthesized and characterized by FT-IR and 1H/13C NMR spectroscopy. Results indicate that both the anion and cation significantly affect depolymerization efficiency; specifically, longer alkyl chain lengths correlated with higher conversion percentages. Anion efficacy followed the order: [Cl−] > [CH3COOH−] > [BF4−]. Furthermore, reaction temperature did not show a significant impact on conversion within the studied range. Spectroscopic data suggest that bond dissociation follows a Brønsted acid-catalyzed mechanism, evidenced by the reduction of phenolic components and guaiacyl/syringyl units in the recovered lignin samples.
