A transient non-linear coupled heat transfer problem with heat conductivity properties being dependent on moisture content has been studied for heterogeneous domain represented by a building exterior structure. Moisture content is considered as a variable parameter linked to material permeability and vapour transfer characteristics as well as amount of moist being condensed and evaporated. The solution to such problem has been obtained by using semi-analytical approach where the governing equations have been discretized by using finite element technique at the spatial domain, and analytically at temporal domain. Picard iteration method has been used for equation linearization. Based on a connection detail of three-layered exterior wall with floor slab, a sample problem has been solved. The results are compared with the results of similar but linear problem.

Currently, qualified personnel is the basis for the development of any enterprise. In modern practice of human resource management, the concept of “personnel potential” is of great importance. It represents the knowledge, skills, and skills of employees that can be used to achieve specific goals and objectives of the enterprise. To improve the activity of an enterprise from the standpoint of human resource management, regular monitoring and evaluation of human resources is necessary. The paper presents a methodology for assessing the efficiency of human resources management on the example of the activities of the company LLC "Bekovsky DFF "Oktyabr""
