Основным способом улучшения массогабаритных параметров импульсных источников питания является уменьшение габаритов магнитного компонента. Наиболее простым способом по уменьшению объема магнитного сердечника является повышение его рабочей частоты. Однако с повышением частоты преобразования магнитного компонента его эффективность может существенно снижаться вследствие возникновения высокочастотных потерь в сердечнике и медных проводниках. В данной работе рассмотрены основные механизмы возникновения высокочастотных потерь в обмотках магнитного компонента. Большинство инженеров при расчете импульсных трансформаторов учитывают только омические потери и потери на скин-эффект. Показано, что с увеличением частоты и количества слоев обмоток эффект близости имеет тенденцию становиться доминирующим в формировании потерь в меди. На примере расчета прямоходового трансформатора показана зависимость потерь в каждом слое обмотки от толщины проводника и частоты. На основе результатов математического моделирования предложен способ оптимизации потерь в моточных изделиях без чередования обмоток с использованием формулы Доуэлла
The main way to improve the weight and size parameters of switching power supplies is to reduce the dimensions of the magnetic component. The simplest way to reduce the volume of the magnetic core is to increase its operating frequency. However, with an increase in the frequency of conversion of the magnetic component, its efficiency can significantly decrease, due to the occurrence of high-frequency losses in the core and copper conductors. In this paper, we considered the main mechanisms of occurrence of high-frequency losses in the windings of the magnetic component. Most engineers take into account only omic losses and skin effect losses when calculating pulse transformers. We show that with increasing frequency and number of winding layers, the effect of shortness tends to become dominant in the formation of losses in copper. We show the dependence of losses in each layer of the winding on the thickness of the conductor and frequency on the example of the calculation of a straight-line transformer. Based on the results of mathematical modeling, we propose a method for optimizing losses in winding products without alternating windings using the Dowell formula

Abstract
Background
A prolonged COVID-19 pandemic could exacerbate the risk of infection and undesirable effects associated with infection control measures of older people with dementia (PWD), and the care burden of families. In this study, we examined the efficacy of care manager-led information provision and practical support for families of older PWD who need care, regarding appropriate infection prevention, prevention of deterioration of cognitive and physical functions, and preparedness in cases of infection spread or infection during the pandemic.

Methods
Fifty-three family members (aged ≥20 years) who were primary caregivers living with older PWD using public long-term care services were enrolled in an one-month randomized controlled trial. This duration was set based on behavior modification theory and with consideration of ethical issue that the most vulnerable people not benefiting from the intervention. The intervention group (IG) received care manager-led information provision and practical support, and the control group (CG) received usual care. Care burden (primary outcome) was measured using the Zarit Caregiver Burden Interview, and secondary outcomes were analyzed using Patient Health Questionnaire-9 (PHQ9), the Fear of COVID-19 Scale, and salivary α-amylase activity. Data were collected at baseline and after 1 month. Multiple regression analysis was conducted to examine the efficacy of the intervention. The participants evaluated the care managers’ support.

Results
The participants were randomly divided into IG (n = 27) and CG (n = 26) groups. After the intervention, compared with the CG, there was a decrease in PHQ-9 (β = −.202, p = 0.044) and α-amylase activity in saliva (β = −.265, p = 0.050) in IG. IG also showed an increased fear of COVID-19 after the intervention (β = .261, p = 0.003). With the care managers’ support, 57.2% of the participants felt secure in their daily lives and 53.1% agreed that they were able to practice infection prevention suitable for older PWD.

Conclusions
Our findings suggest that the care manager-led intervention may be useful for families of older PWD to enhance behavioral changes in preventing COVID-19 infection and improve their psychological outcomes in the COVID-19 era.

The present study aims to identify the quality of family life and its relationship to psychological stress for children with hearing disabilities from the point of view of their parents in Jordan. The study included 100 parents of students with hearing disability. The paricipants were selected according to the available method. In order to achieve the goal of the study, the researchers constructed two scales, namely the scale of quality of family life and the scale of psychological stress. The validity and reliability indications of the two measures were acheived. The results indicated that family interaction came first, material well-being second, emotional well-being ranked third, and emotional well-being came in last place. In general, the quality of family life was average. The results also showed that the psychological stress was moderate. The results also indicated that there was no statistically significant relationship between the quality of family life and psychological stress. The results also maintained that there were no statistically significant differences in the quality of family life for participants due to the variables, the sex of the guardian, the education level of the parents, and the economic income. The results stressed that there were no statistically significant differences in the level of psychological stress of the participants according to the variables of the guardian’s sex, the parent's education level, and economic income.

The study aims to measure basic psychological needs’ satisfaction-frustration among undergraduate GCC students’ and to investigate the function of satisfaction or frustration of the basic psychological needs on positive mental health or depressive symptoms. To achieve these aims, three measures have administered on a sample consisted of 608 undergraduate students from three GCC countries (Oman, Qatar, and Saudi Arabia: (1) Basic Psychological Needs Satisfaction Frustration Scale (BPNSFS), (2) Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and (3) The second edition of the Beck Depression Inventory (BDI-II). Descriptive statistics explored that the level of needs satisfaction was high and convergent to a certain extent in the three countries, while the level of frustration was moderate with some disparity among the three countries. The results also showed a clear pattern of correlation between the level of satisfaction and mental health, and correlation between frustration and depressive symptoms. Finally, Multiple Regression Analysis showed that it is possible to predict individuals’ mental health according to their satisfaction or frustration with the basic psychological needs. The study concluded that basic psychological needs’ satisfaction is positively associated with mental health, while needs frustration is associated with depressive symptoms. Thus, these results, provides additional evidence from the Arab context on the integrity of the foundation on which the Basic Psychological Needs Theory is based.

TERRITÓRIO, SUBJETIVIDADE E RECEPÇÃO: A Festa do Coco criando espaço incorporado
Authors: Moraes Peticia Carvalho de 
Published: August 2022

Este artigo é parte integrante de minha dissertação de mestrado realizada na Universidade de São Paulo (USP), no programa de Estudos Culturais na área da Filosofia. Ao longo do texto, discuto as negociações realizadas durante a Festa do Coco das comunidades quilombolas paraibanas Ipiranga e Gurugi que evidenciam maneiras de como ocorre a construção do espaço subjetivo da festa através das inter-relações entre as trajetórias humanas e não humanas e suas subjetividades. Chamo de construção do espaço subjetivo as outras linhas de vida estabelecidas no local da festa e que também organizam a construção de seu território, como o círculo, evidenciado na formação da roda de coco, e as pequenas linhas retas, produzidas pela ligação entre as duplas brincantes no centro da roda. Esta construção do espaço subjetivo da festa se dá juntamente com a linha retangular da arquitetura do local: o formato do barracão. Os estudos da Estética da Recepção me ajudaram a discutir a relação entre o público das festas, seus horizontes de expectativa e suas produções de subjetividade, ou seja, os processos de criação de subjetividades que ocorrem durante a festa e a brincadeira.
DANÇA E MÚSICA DE BLOCOS AFRO: fundamentos de uma poética e política negra
Authors: Conrado Amélia Vitória Souza , Conceição Sueli Santos 
Published: August 2022

A abordagem sobre Dança e Música dos Blocos Afro na cidade de Salvador-Bahia enfatiza os princípios que orientam uma poética e política negra enquanto uma forma de organização social e estratégia do Movimento Negro contemporâneo. Identifica-se que as instituições da educação oficial, em todos os níveis, não vem contemplando os conhecimentos e saberes que as instituições artístico-culturais negras produzem, apesar das ações e políticas afirmativas do Movimento Negro Unificado junto ao Estado brasileiro para o reconhecimento e valorização da sua identidade cultural. Nesse sentido, alguns autores auxiliam a definir conceitos, articular pressupostos e chegar a algumas evidências, tais como Santos (2003), Santos (2015), Gomes (2017), Silva (2011), entre outros. Acredita-se que somente com uma mudança de pensamento e ação compartilhada, em que a arte permaneça atuando em um campo do sensível e das questões humanas, poderemos almejar transformações nas formas políticas de emancipação e, portanto, de luta antirracista.
