Purpose. The development of the control system for three-phase network is based on intelligent technologies of network-centric control of heterogeneous objects. The introduction of unmanned aerial vehicles for monitoring of three-phase network increases the efficiency of management. Methodology. The case of decomposition of the instantaneous capacities of the fixed and variable components for 3-wire system. The features of power balance for the different modes of its functioning. It should be noted that symmetric sinusoidal mode is balanced and good, but really unbalanced, if the standard reactive power is not zero. To solve the problem of compensation is sufficient knowledge of the total value of the inactive components of full power (value of the inactive power) without detail. The creation of a methodology of measurement and assessment will require knowledge of the magnitudes of each inactive component separately, which leads to the development of a unified approach to the measurement and compensation of inactive components of full power and the development of a generalized theory of power. Results. Procedure for the compensation of the current of zero sequence excludes from circuit the source, as the active component of instantaneous power of zero sequence, and a vector due to a current of zero sequence. This procedure is performed without time delay as it does not require integration. Only a 3–wire system with symmetrical voltage eliminates pulsations and symmetrization of the equivalent conductances of the phases of the task. Under asymmetric voltage, the power is different, its analysis requires the creation of a vector mathematical model of the energy processes of asymmetrical modes of 3–phase systems. Originality. The proposed method extends the basis of the vector method for any zero sequence voltages and shows that the various theories of instantaneous power three wired scheme due to the choice of a basis in a two-dimensional subspace.

The Role of Adverse Childhood Experiences and Corporal Punishment in Early Adulthood Depression and Substance Use among Ukrainian College Students

The Role of Adverse Childhood Experiences and Corporal Punishment in Early Adulthood Depression and Substance Use among Ukrainian College Students / Viktor Burlaka, Jun Sung Hong, Iuliia Churakova and oth. // Journal of Family Violence. - 2020. - Vol. 35, Issue 3. - P. 285–295. - DOI: 10.1007/s10896-019-00110-x.Насильство щодо дітей є всесвітньою проблемою, і великий обсяг досліджень демонструє як короткострокові, так і довгострокові негативні результати. У цьому дослідженні використовується моделювання структурних рівнянь для вивчення шляхів від використання батьками тілесних покарань і несприятливих переживань в дитинстві до депресії і вживання психоактивних речовин в зрілому віці. Результати цього дослідження показують, що молоді люди в Україні, які пам'ятають, що з ними погано поводилися в дитинстві мають більш високий ризик розвитку депресії і вживання психоактивних речовин в дорослому віці.Violence against children is a worldwide problem, and a large body of research demonstrates both short-term and long-term negative outcomes. The present study employs structural equation modeling to examine the pathways from parents’ use of corporal punishment and childhood adverse experiences to depression and substance use in adulthood. Cross-sectional data were collected from a sample of 944 students (Mage = 19.16, 69% females) attending ten public universities in 27 Ukrainian regions. The model provided a good fit for the data: χ2 (59, N = 944) = 189.49, p < 0.001, CFI = 0.96, TLI = 0.95, RMSEA = 0.048. Higher scores on adverse childhood experiences (ACE) maltreatment items (psychological, physical and sexual abuse during childhood; b = .26, p < .001) were associated with higher depression during adulthood. Higher depression scores were linked with higher multiple substance use (b = .17, p < .001). Childhood adverse experiences had significant standardized indirect effect, mediated by depression, on adulthood involvement in substance use (b = 0.043, p < 0.01). Findings from this research suggest that young adults in Ukraine who remember being maltreated as children have a higher risk to develop depression and engage in substance use as adults.Насилие в отношении детей является всемирной проблемой, и большой объем исследований демонстрирует как краткосрочные, так и долгосрочные негативные результаты. В настоящем исследовании используется моделирование структурных уравнений для изучения путей от использования родителями телесных наказаний и неблагоприятных переживаний в детстве до депрессии и употребления психоактивных веществ в зрелом возрасте. Результаты этого исследования показывают, что молодые люди в Украине, которые помнят, что с ними плохо обращались в детстве имеют более высокий риск развития депрессии и употребления психоактивных веществ во взрослом возрасте

Purpose. Information technologies allow multidimensional analysis of information about the state of the power system in a single information space in terms of providing network-centric approach to control and use of unmanned aerial vehicles as tools for condition monitoring of three-phase network. Methodology. The idea of energy processes in three independent (rather than four dependent) curves vector-functions with values in the arithmetic three-dimensional space adequately for both 4-wire and 3–wire circuits. The presence of zero sequence current structural (and mathematically) features a 4-wire scheme of energy from a 3-wire circuit. The zero sequence voltage caused by the displacement of the zero voltage phases. Offset zero in the calculations can be taken into account by appropriate selection of the reference voltages. Both of these energetic phenomena with common methodical positions are described in the framework of the general mathematical model, in which a significant role is played by the ort zero sequence. Results. Vector approach with a unified voice allows us to obtain and analyze new energy characteristics for 4–wire and 3–wire circuits in sinusoidal and non-sinusoidal mode, both in temporal and frequency domain. Originality. Symmetric sinusoidal mode is balanced, even with non-zero reactive power. The converse is not true. The mode can be balanced and unbalanced load. The mode can be balanced and unbalanced voltage. Practical value. Assessing balance in network mode and the impact of instantaneous power on the magnitude of the losses, will allow to avoid the appearance of zero sequence and, thus, to improve the quality of electricity.Обеспечение сетецентрического подхода к режиму управления трехфазной сетью и оценка сбалансированности режима сети с учетом влияния мгновенной мощности на величину потерь даст возможность исключить появление нулевой последовательности и, тем самым, повысить качество электроэнергии
