A Submersible Printed Sensor Based on a Monopole-Coupled Split Ring Resonator for Permittivity Characterization.

This work presents a non-invasive, reusable and submersible permittivity sensor that uses a microwave technique for the dielectric characterization of liquid materials. The proposed device consists of a compact split ring resonator excited by two integrated monopole antennas. The sensing principle is based on the notch introduced by the resonators in the transmission coefficient, which is affected due to the introduction of the sensor in a new liquid material.

[Morbidity of Chronic Obstructive Pulmonary Disease in Colombia. Results of the study SANEPOC-2].

Objective: to relate the morbidities of patients belonging to the COPD program of a health institution in Anserma, Caldas (Colombia).

Material And Methods: a descriptive study was presented with a sample of 51 patients who underwent exploratory spirometry, the findings were contrasted with the main commodities reported by the patients or the Medical Record through descriptive and inferential statistics.

Results: 50% of the evaluated population had at least one recorded comorbidity; the main morbidity found was Arterial Hypertension followed by Chronic Kidney Disease; an associated behavior was found between the GOLD classification and the presence of symptoms with non-statistically significant values; no statistically significant association was found between comorbidities and spirometric values.
