Methodology for assessing social and economic efficiency of digitalization of health system by A. A. Alimbaev, B. S. Bitenova, T. I. Yesenbekova

“…It was revealed that these methods do not consider an important generalizing indicator as gross value added, which, from the perspective of the economy as a whole, is taken into account in the country’s gross domestic product.The article proposes a methodology for assessing the economic and social effectiveness of digitalization of the healthcare system, which allows us to consider gross value added as a generalized result characterizing the production and sale of services, and as the efficiency of resource use in the process of providing medical services.This methodology is based on the theory of efficiency and the law of saving time, as well as approaches to determining criteria and performance indicators.…”

Relationship between radon and oxygen diffusion coefficients in OPC concretes by P. Linares-Alemparte, M. Souto-Allaoui, C. Andrade-Perdrix

“…As concrete often forms the building envelope with the ground, it is interesting to investigate its performance as a barrier, i.e. its radon exhalation, which depends on the radon diffusion coefficient and thickness. Experimentally obtaining the radon diffusion coefficient in concrete is complicated, so it would be useful to be able to use an analytical method for its estimation from parameters that are easier to obtain, such as the oxygen diffusion coefficient, which can be determined experimentally with less difficulty and could even be estimated analytically. …”
