The aim: This article aims to analyze the rates of suicide as an indicator of public mental health, to consider the suicidal map of the territory of Ukraine (including to check the manifestation of such a territorial characteristic as the Albanian paradox); calculate the price of suicide for the socio-economic development of the Ukrainian state, consider the risks of suicide that have arisen as social and criminological consequences of the COVID-19 pandemic. Materials and methods: The study is based on the analytical materials of the Ministry of Health of Ukraine and the WHO; the information and analytical data of the General Prosecutor's Office of Ukraine, the State Statistics Service of Ukraine and sectoral statistics for the period of 2015-2019, etc. The article is based on dialectical, analytical, synthetic, comparative, statistical, cartographic, and sociological methods of research and the method of potential demography. The theoretical basis of the article is specialized literature on medicine, suicidology, law, sociology, and cartography. Results: In Ukraine, the death rate from suicide in recent years averages 1.1% of the total number of deaths. The rate of suicide decline in Ukraine has slowed significantly over the past five years, which is an alarming symptom. There are almost strict proportions between male and female suicide (men commit four out of five suicides). The level of self-harm per 100,000 population of Ukraine remains almost stable, indicating a severe demographic crisis in Ukraine. Women in Ukraine are less likely to commit suicide than in European countries. In Ukraine in recent years, contrary to European trends, suicide has dominated among the elderly aged 65+. The number of years of potential life loss for male and female suicides in Ukraine is 103 thousand, and the number of working years is almost 100 thousand. The losses for Ukraine from the unlived life of those who died as a result of suicide in 2019 are almost USD 341 billion. Conclusions: In 2019, suicides accounted for almost 21% of deaths from external causes among Ukraine's population. The most intense suicidal situation is observed in the central part of the country's geographical map along the imaginary vertical axis “North-South” (Kherson, Chernihiv, Cherkasy, Vinnytsia, Zaporizhia, Kirovohrad, Sumy, Poltava, Dnipropetrovsk, Mykolaiv regions). During the COVID-19 pandemic, many additional factors increase the risk of suicide among individuals who are at heightened risk of suicide or are actively suicidal, and among the general population.

The official statistics of the Prosecutor General's Office of Ukraine has recorded that in 2017 the number of cases of human trafficking from Ukraine increased threefold (342 cases versus 115 in 2016). Such a sharp growth of the aforementioned crime was last observed in 2005 to 2006. Today, there are no administrative and territorial districts in Ukraine from which future victims of human traffickers would not be recruited. According to criminal proceedings, about 70% of human trafficking victims are residents of large Ukrainian cities. The aim of this research is to investigate current trends of human trafficking phenomenon from Ukrainian cities and villages and to present the ways how the victims fall into slavery. The revealed trends of the human trafficking from Ukraine allow us to affirm that whereas similarity of social and demographic, moral and physiological characteristics of urban and rural residents, the second ones have a higher level of risk to become a victim of human trafficking. The results obtained allow us to develop evidence-based recommendations for the human trafficking from Ukraine decreasing as from the hole country, as rural locals, in particular. The new feature in human trafficking is a negative trend that Ukraine is changing from the country in which human trafficking victims originate into the destination country for human trafficking.

Introduction: All social life spheres in Ukraine are influenced by corruption. Ukrainian citizens were inquired in order to determine corruption rate in various social spheres. It was conditioned by reforming criminal justice and administrative management, which is directed, particularly, for liquidation of corruption in the state. Special emphasize is stressed on corruption rate in the medical sphere. The aim of the article is to determine: 1) population’s attitude towards to corruption, in particular, in the medical sphere; 2) the most corruptive social spheres; 3) efficiency of anti-corruption measures; 4) readiness of population to participate into struggle with corruption. Materials and methods: The study is grounded on dialectical, comparative, analytic, synthetic, sociological (special-purpose inquiry form, interview), statistic and comprehensive research methods. The study group consisted of 1 120 citizens and 513 medical and pharmaceutical professionals of Ukraine. Questions were related to: 1) citizens’ contact with corruption; 2) corruption expansion rate in state authorities, self-governing authorities, in various infrastructure spheres, particularly, in healthcare; 3) awareness about struggle with corruption in the state and in the region and determination of citizens’ readiness to cope with corruption. Results: Corruption contact level of citizens remains steadily high. Corruption in the medical sphere is the most widespread: during the previous year before the inquire 63% respondents were involved into corruptive schemes. Corruption in the medical sphere can be subdivided in the following levels: from patient to doctor; inside the hospital – from a healthcare institution employee to the executive hospital staff; on state level concerning state procurements of medications. A bribe to health care professionals was given for: receipt of a sick leave certificate and various references (for example, about unfitness for military service, fitness for driving a car or fulfillment of particular works); high-quality conduct of an operation, medical servicing rendering; writing out a “necessary” prescription; approval or hiding of any bodily injuries; falsification of a true cause of death. All health care professionals have come across different corruptive practices, among which the following payments are widespread: for employment in a hospital, license for private medical practice or establishment of private clinics, “avoidance” of checks of healthcare institutions’ activity. The largest bribes are given state officials for participation in tenders for medical drugs supply by pharmaceutical companies. All health care professionals have come across different corruptive practices, among which the following payments are widespread: for employment in a hospital, license for private medical practice or establishment of private clinics, “avoidance” of checks of healthcare institutions’ activity. Conclusion: Corruption on the sphere of medical practice is complex phenomenon. The conducted poll made it possible to structure the corruption problem, to see its various levels and levels. In respondents’ opinion, a scrupulous information campaign is a positive tendency: 45% consider this is a guarantee of anticorruption. Nevertheless, only 5% respondents assume personal notification of anticorruption bodies about receipt of a bribe by medical staff.

In widespread sources the results of calculations of the sizes of contact planes of anellipse form at interaction of locomotive wheels with rails of type P65 which small axes make 5-10mm depending on loading taking into account dynamic influence are resulted. These data do notcorrespond to the purpose and objectives of this study, which is to determine the size of the half-axisof the contact plane under vertical load on the head of the rail thread in the range from 100 kN to180 kN, when the wheel of the freight car rests on a bevel a wheel having a conicity of 1:10, with awheel radius r1 = 475 mm and a rolling surface radius of the rail head r2 = 80 mm. The size of thecontact plane of support of the rim of the wheel of a freight car on the surface of the head of the railtype P65 is determined in the work. The calculations were performed on the basis of preliminarydetermination of the location of the mathematical point of contact on the box curve, which outlinesthe surface of the rail head in cross section under deterministic conditions of pressing intermediaterail fasteners of separate type under the action of outstanding accelerations for freight -0.3 m / s2.The purpose of the calculations is to obtain the practical value of the maximum dangerous width ofthe rail track, which corresponds to the conditions of track expansion at vertical wheel load on therail 140 kN and at maximum spacing forces that provide the highest values of lateral displacementsrail thread with a surface adjacent to the chamfer of the wheel rim. Based on calculations by the Hertz-Bilyaev method, it was obtained that the average value of the contact strip of the rail and therim of the wheel of a freight car, at a vertical load P = 140 kN, is: b = 3.2 mm, so b / 2 = 1.6 mm.But if you round to the accuracy of measuring the width of the rail track - b / 2 = 1.6 mm.

General national average drug crime rates on which the contemporary criminological theory and practice is based do not adequately reflect regional peculiarities in the field of illicit drug trafficking as they level high quality/quantity parameters in some areas and their lower values in others. Still, consideration of only national totals in organization of crime counteraction leads to incomplete information, neglecting its negative trends in certain areas, thus, causing aberration of the actual drug crime situation and using improper countermeasures. Under such circumstances the state law enforcement agencies do not operate preemptively against the illicit drug trafficking, do not contain in due time outbreaks of drug crime in certain areas- crime donors, and, as a result, the efficiency of steps aimed at drug addiction prevention as well as crime limitation in total becomes substantively deteriorated. Criminological mapping method enables the territorial police divisions to monitor existing criminological situation, inform the public and other law enforcement agencies on trends and locations of drug crime expansion, and reveal the most affected areas to be able to react promptly to crime pattern changes in regions. The application of this method enabled the evident demonstration of the fact that in Ukraine the Eastern and Southern areas were most affected by drug crime, wherein the affection factor in this part is twice higher than general national value.
