The number of incidences is increasing disproportionately in countries with middle and low incomes compared to high-income countries. Mortality caused by diabetes mellitus occurs in 20.9 people per 100,000 of the country's population. Several causes of the high incidence of mortality caused by DM, include delays in determining a diagnosis and non-adherence to treatment. Health center cadres are an extension of the puskesmas in reaching out to the community in the working area of each public health center. Based on this context, this activity aimed to educate health center cadres in regard to early detection of DM and complications related to DM in order that they can educate the public and motivate them to cooperate in the treatment of DM. After the education program was implemented, an increase in knowledge about DM was found among health center cadres. This finding was determined by looking at the mean score, which increased from 74.8 during the pretest to 84.4 during the post-test.

The use of the DiSCmini has developed considerably in the context of evaluating inhalation exposure to nanoparticles. This article presents the results obtained during measurement campaigns at workplaces. A few examples describe the applicability of the DiSCmini to measure nano-objects in different metrics complementary to standard exposure measurement methods.

This article is the follow up of the instrument’s working principle description and laboratory comparison [1], that showed its ability to determine personal exposure to ultrafine particles and nano-objects in the size range below approximately 700 nm. Besides the number concentration, also the surface area concentration as well as a mean diameter of the aerosol is determined. The DiSCmini is one of the few instruments allowing person mounted use to measure directly the personal exposure to ultrafine particles. For a more comprehensive exposure determination, other instruments can be useful like direct reading instruments for the size range above 700nm, in addition to conventional aerosol samplers for mass concentrations. Although occupational exposure limit values for a number concentration are not in use for ultrafine particles or nano-objects, number based reference values can be chosen for an assessment of the exposure [2]. Such easy to use instruments like the DiSCmini can also be used in a tiered approach for exposure determination of nano-objects as described in a European Standard [3]. The first two phases of the latter approach is a suitable application to get an overview of the concentrations. Another application for such direct reading instruments will be the assessment of protective measures at particle emitting processes, e.g. the application of local exhaust ventilation [4]. Further experience in using the DiSCmini in the laboratory and the field was described in [5, 6, 7], while a review on exposure measurement methods for nano-objects is given in [8]. The following part describes examples of use of the DiSCmini and should help the reader to plan such applications and show which data can be expected.

Published: August 2023

A pesar de los avances en la sociedad actual, el tema de sexualidad sigue siendo un tabú en muchos países latinoamericanos este problema fragmenta su entendimiento y comprensión trayendo consigo consecuencias negativas en la vida personal y social de las personas puesto que la sexualidad es un aspecto fundamental biopsicosocial y espiritual en el desarrollo humano. La investigación analizó la deficiencia de la educación sexual, por la falta de acceso a información confiable, por el conservadurismo de los padres, por los enfoques diversos que tienen las instituciones educativas, por la deficiencia de dialogo abierto sobre estos temas y el nivel de conocimientos de universitarios sobre la sexualidad. El abordaje metodológico se realizó en el paradigma sociocrítico con un enfoque mixto, de tipo observacional analítico con corte trasversal, en la población universitaria de varias instituciones de educación superior de la carrera de medicina tanto públicas como privadas a partir de una muestra probabilística aleatoria de 384 estudiantes mayores de 18 años quienes dieron su consentimiento informado para la investigación, los resultados demostraron que los estudiantes universitarios de la carrera de medicina no tienen claridad plena sobre los conocimientos en sexualidad. La propuesta apertura un espacio dialógico en ámbito universitario para promover una salud sexual y reproductiva con enfoque integrador complejo religado a las múltiples dimensiones del ser humano. Las conclusiones fueron analizadas por un grupo de estudiantes quienes reflexionaron sobre las repercusiones de la deficiencia de conocimientos sobre sexualidad en jóvenes de educación superior universitaria.
