ABSTRACT
The radical transformations caused by the rapid development of information and communication technologies in the mid-1990s prompted the transition to the knowledge society which identified the key role of knowledge as the most important and valuable capital of organizations and had a decisive impact on the development of corporate training. In our study, we aimed to analyze the training methods used in American companies in the knowledge society, particularly, their feasibility, features, benefits and possible limitations. The results of our study show that, at present, e-learning is considerably more widely used in American companies than instructor-led classroom training. Most organizations use blended learning which implies the combination of e-learning methods and instructor-led learning methods. A powerful stimulus for the wide implementation of e-learning methods was produced by the COVID-19 pandemic when the use of educational technologies made it possible for the companies not only to continue training and development of their employees but also to implement tactical and strategic practices which will have long-term implications for the future of the training industry. The most widely used e-learning methods in American companies are virtual classroom/webcast, online or computer-based methods, social learning, augmented reality, virtual reality, and artificial intelligence. In spite of certain limitations of e-learning methods, they have a number of important benefits which allow companies to expand access to training, save costs, increase adaptability and flexibility of learning programs, etc., and thus satisfy their needs in qualified employees.
ABSTRACT
OBJECTIVE: The aim: Of this study was to analyze epidemiological data on the detection of immunoglobulins of class M and G (IgM, IgG) to SARS-CoV-2 among urban and rural population of Poltava region. PATIENTS AND METHODS: Materials and methods: We have analyzed the research results of 2841 patients to determine IgM and IgG levels to SARS-CoV-2. The study included the results of patients in Poltava and nearby villages of Poltava region, obtained during July - December 2020. RESULTS: Results: Thus, 84% of patients applied for detection of IgM in the serum of patients with the pathogen COVID-2019. We have found only 135 positive results for the detection of IgM to SARS-CoV-2, which was 5.7% of the total number of people who underwent this study from July to December 2020. Moreover, women received a positive result more often than men. The IP samples for the detection of IgM to SARS-CoV-2 in the serum of patients averaged 2.5 +/- 1.04. It was found that patients went to the laboratory to detect IgG to SARS-CoV-2 with the vast majority among them were residents of Poltava. However, in this case the share of positive results was 47.7%, among which the female population outnumbered the male. CONCLUSION: Conclusions: The frequency of detection of positive results on IgM to SARS-CoV-2 is about 6%. The share of positive results on IgG to SARS-CoV-2 was 47.7%, among them 76.2% were women. The frequency of detection of IgM and IgG to SARS-CoV-2 during October-December 2020 significantly exceeds the indices in July-September of the same year.
