ARTIFICIAL CRISES IN FINANCIAL MARKETS: PROBLEMS OF DIAGNOSIS AND PREVENTION

Purpose: The aim of this study is to diagnose and prevent crises in the country's financial markets by managing the connectedness of the attacked market with other.   Theoretical Framework: Non-statistical changes in the largest connected markets and the parameters of the attacked market's connection with them. There is a need to consider ways to counter crises by managing the connection of the attacked market with other financial markets in the country.   Design/Methodology/Approach: Methods for diagnosing crises are proposed to identify signs of a man-made crisis and strategies for its prevention. The proposed approach will prevent the actions of unscrupulous private financial market operators who want to receive unscrupulous income, stimulating volatility.   Findings: Among the most important results, it was determined that there are serious shortcomings in the organization and structure of financial markets that require active government intervention. The state can not only legislative and administrative, but also financial methods prevent the actions of dishonest operators or minimize the consequences of the crises caused by them.   Research, Practical & Social implications: This study makes it possible to identify signs of an artificial crisis and strategies for its prevention. Using the data of this study, the state operator in the financial markets can distribute its financial, administrative and informational resources in turn against its opponents and thus have a significant advantage over each of them.   Originality/Value: The value of the study lies in the fact that various methods for diagnosing financial crises are offered by studying non-statistical changes in the largest connected markets and the parameters of the attacked market's connection with them. Using this information, the state can minimize the consequences of artificial financial crises

METHOD OF PROTECTING SPECIALLY IMPORTANT OBJECTS BASED ON THE APPLICATION OF THE BISTATIC RADIOLOCATION TECHNIQUE

The solution of the tasks assigned to the National Guard of the state implies the presence of certain forces and means with the appropriate technical equipment. A well-known place among such tasks is security of important state facilities. Various physical effects and methods, including radar, are used to create security systems. The development of radar technology and technology made it possible to increase both the quantity and quality of the received information, as well as the use of radar stations for observing living objects. The industry today produces bioradioradars for detecting people and controlling their movements. All samples are made in a single-position version and have a relatively high cost, the fact of their work is easily detected, which facilitates their suppression, including force. In order to increase the secrecy of work, it is proposed to use the methods of separated, more precisely, bistatic location to control the area in front of particularly important objects. The defining detection index is the effective reflective surface (ERS), which is about 1 m2 for a person. Equipment, weapons and protective equipment contributes to the increase in the ERS. Given the small reflective surface of biological objects, it is proposed to limit the area of responsibility to the sector form in which, at a certain bistatic angle, the effect of a significant increase in the signal/(interference+noise) ratio is manifested. For a specific definition of the gain, it is necessary to choose the operating frequency of the bistatic system and its geometry. For greater secrecy, it is advisable to use the transmitters of radio and television broadcasting, mobile communications, etc. The estimates found, for example, when using digital television transmitters (T2), indicate that the creation of a secretive bistatic system is quite possible – at least in a geometric interpretation

Determination of the Critical Time of Fire in the Building and Ensure Successful Evacuation of People

An engineering method was developed for determining the critical time of fire and determining the probability of evacuation of people from zone of fire, which makes it possible, with simplified dependencies, to quickly determine all the necessary factors in the evacuation process of people in case of fire in the building. To explain the use of the developed method, the sequence and example of determining the critical time of fire and determining the probability of evacuation of people from zone of fire for enterprise is considered. It was shown how one could calculate the time of evacuation of people from the premises from the zone of fire. The safety of people is provided when the time of evacuation does not exceed the time of the onset of the critical phase of the development of fire. For this purpose, the period for which the temperature, smoke density, oxygen concentration, hydrogen chloride, carbon dioxide and carbon monoxide gas reaches extremely dangerous values for a person was calculated. After determining all the necessary quantities, the probability of evacuation of people was analyzed in the absence of firefighting equipment in the building. The parameters determined by this new method are adequate and confirmed by other methods of calculation, in particular, developed by Hulida, Koval and FDS program. The relative error between the specified parameters does not exceed 8...12% (in comparison with other mentioned methods)

Methodological principles of research in the field of ensuring evidence collection (on the example of cybercrimes): criminal-legal, criminal-procedural, and forensic aspects

The complexity, multifacetedness, and interdisciplinary status of ensuring the collection of evidence leads to the need to study it in the coordinate system set by different levels of scientific methodology. With this in mind, we consider it necessary to analyze the current issues of study methodology in ensuring evidence collection on the basis of cybercrimes. The purpose of the work is studying the criminal-legal, criminal-procedural, and forensic aspects of the methodological foundations of research in securing evidence on the example of cybercrimes. The research methodology includes such methods as the general system-structural method, the dialectical method, the historical method, the system method, the comparative-legal method, logical methods (deduction, induction, analogy, analysis, synthesis), the structural-logical method, and the modeling method. As a conclusion of the conducted research, the regulatory and legal factors that constitute the legal basis of the organizational and technical principles of the investigation of crimes in the field of cybercrime were considered, and the problematic issues of the research methodology were identified. It was concluded that the methodological support of the research of evidence collection is a complex, multifaceted task of scientific research, it can be solved only on the basis of a systematic approach to this problem

Bereavement and covid-19: prevalence, comorbidity, and associated features among ukrainian sample

Objective: The aim: To examine the features of experiences of bereavement reactions and the severity of comorbid mental health problems in persons who lost loved ones during the pandemic. Patients and methods: Materials and methods: 191 volunteers aged 18-60 years participated in this study. All participants were tested during 2018-2020. To assess the mental health problems was used International Neuropsychiatric Interview (MINI) and a set of IAPT scales; to the psycho-emotional distress severity associated with loss of loved ones - Inventory of Complicated Grief, with verification of symptoms of complicated grief based on an independent assessment of two experts; and the quality of life satisfaction was assessed by the Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form. Results: Results: The results show an association between the severity of symptoms of depression, general anxiety, social avoidance, and loss during the pandemic. The level of psycho-emotional distress was associated with the experience of bereavement as a traumatic event for a group of participants who experienced loss during the pandemic and, at the same time, before the pandemic was associated with the severity of depression. Regardless of the time of loss, people who demonstrated signs of complicated grief have a more pronounced comorbid psychopathology, a higher level of psycho-emotional distress, and a lower level of satisfaction with life quality. Conclusions: It has been established that a person's ability to experience loss as a traumatic experience and grieve during the pandemic is modified with the context of the life situation and reflects those challenges that impose quarantine restrictions
