The reliability of the human operator is an essential indicator of the safe operation of nuclear power plants. Mistakes can be made during performance checks, maintenance, at the stage of accident management, etc.The need to take into account the human factor in the analysis of safety and reliability of nuclear power plants is justified by the fact that erroneous actions of personnel and operators of nuclear power plants directly or indirectly can lead to accidents. Therefore, the analysis of personnel reliability (ANP) when performing a probabilistic safety analysis (PSA) and risk assessments afford to identify the most likely erroneous actions of NPP personnel and to develop a set of measures to reduce them.Depending on the likely consequences of the accident and the time available to the operator for the intervention, the personnel will be exposed to various levels of stress, which will directly affect the personnel's actions to troubleshoot in the event of an emergency. If an accident has occurred, then in a short period of time the operator needs to make a number of decisions, the correctness of which can both save and aggravate the situation.This paper considers the issues of visualization of bibliometric networks of scientific publications on the study of the human factor in the operation of nuclear power plants.
The accelerating evolution of scientific terms connected with 4P-medicine terminology and a need to track this process has led to the development of new methods of analysis and visualization of unstructured information. We built a collection of terms especially extracted from the PubMed database. Statistical analysis showed the temporal dynamics of the formation of derivatives and significant collocations of medical terms. We proposed special linguistic constructs such as megatokens for combining cross-lingual terms into a common semantic field. To build a cyberspace of terms, we used modern visualization technologies. The proposed approaches can help solve the problem of structuring multilingual heterogeneous information. The purpose of the article is to identify trends in the development of terminology in 4P-medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
