The demographic low, and thus the inevitable aging of the populations of economically developed countries, makes it necessary to extend the working life of citizens. Therefore, an increasing percentage of workers are representatives of the so-called “silver” generation, i.e., people over 50 years of age. The main objective of the study is to characterize the system of values, attitudes to work, and related expectations of professionally active women and men over 50 years of age and to determine whether, and if so, how the hierarchy of values, attitudes to work, and job satisfaction affect the further development of their professional careers. In order to achieve such a goal, a CAVI survey was conducted on a sample of n = 600 respondents. The statistical significance of the differences between the groups was tested with the Mann–Whitney U test. To verify the main hypothesis, ordinal logistic regression models were built. The results of the study were supplemented with elements of descriptive statistics. In the course of the research work, it was confirmed that there are significant differences between the studied men and women in the assessment of traits concerning their value hierarchy, attitudes towards work, and career prospects. Traits such as value hierarchy and attitudes toward work have a significant impact on the career development of both women and men of the “silver” generation, while job satisfaction shows a significant impact on career development only for women.

The main objective of the research presented in the following work was the adaptation of reflection-radar technology in a detection and navigation system using radio-tomographic imaging techniques. As key aspects of this work, the energy optimization of high-frequency transmitters can be considered for use inside buildings while maintaining user safety. The resulting building monitoring and control system using a network of intelligent sensors supported by artificial intelligence algorithms, such as logistic regression or neural networks, should be considered an outcome. This paper discusses the methodology for extracting information from signal echoes and how they were transported and aggregated. The data extracted in this way were used to support user navigation through a building, optimize energy based on presence information, and increase the facility’s overall security level. A band from 5 GHz to 6 GHz was chosen as the carrier frequency of the signals, representing a compromise between energy expenditure, range, and the properties of wave behavior in contact with different types of matter. The system includes proprietary hardware solutions that allow parameters to be adjusted over the entire range and guarantee adaptation for RTI (radio tomography imaging) technology.

The study aims to evaluate the way for creating agile institutions with organizational trust. Besides that, the understanding of the mediating role played by psychological empowerment during COVID-19 pandemic is one of the major objectives of this study. The way psychological empowerment affects the creation of agile organizations is another major aspect that the study investigated. The philosophical stance that the research has adopted is the positivism philosophy. The study was done by collecting and analyzing quantitative data. The approach for the study is deductive whereas the design of the research is descriptive. The study used a survey method for collecting information. Structural equation model was used for analyzing quantitative information. The study was done on 325 samples who are working at the finance sector of Turkey. All the samples have a residence in Turkey. It was identified that the leadership approach of a company has a huge impact on the psychological construction of the samples. Descriptive statistics and t-test for inferential statistics were done by the researchers. There is a strong positive relationship between the centricity of the organization towards the workforce or customer and employee performance. It was identified that the leadership approach helps employees to address and adopt the change in the marketplace. It was also found that an agile organizational structure has more possibilities to modify the processing based on the change in the marketplace. The structural equation model was used to represent the relationship between the variables.
