“…that interfere (for example, the state of hearing, intelligence, physical activity, etc.). Liu et al [17] determined the importance of using inertial sensors to assess the static balance of preschoolers. At the same time, the angular velocity module is considered by them to be more reliable than the acceleration module.…”

Purpose: to reveal the reliability of the effectiveness of the developed author's system for correcting the physical development of young and preschool children with psychomotor disorders. Material and methods. A total of 208 children of early (2-3 years) and younger preschool (3-4 years) age with psychomotor disorders took part in the study. Specially organized studies of the effectiveness of the system of corrective physical education for children of early and younger preschool age with psychomotor disorders were conducted during 2019 - 2021. They took place in specialized preschool education institutions, as well as kindergartens of the combined type in the city of Odesa, Odesa region, as well as in the cities of Kramatorsk, Kharkiv, Mykolaiv, Balaklia (Kharkiv region). I also summarized my own long-term (over 25 years) experience of individual rehabilitation activities with the specified contingent of children in the Odessa Movement Rehabilitation Center. All children were divided into two groups: 108 from experimental groups and 100 from control groups. Results. Summarizing the analysis of the results of the dynamics of physical development indicators of children with psychomotor disorders (on the example of the study of their posture), we should conclude that almost all the indicators of children from the experimental groups had a marked improvement in results, which in the absolute majority of cases was confirmed statistically (P<0,01‒0,05). Children from control groups also demonstrated some improvement of physical development indicators, but it was by no means confirmed by the methods of mathematical statistics (P>0,05). Conclusions: the conducted formative pedagogical experiment confirmed the reliability of the effectiveness of the developed author's system of correction of physical development of children of early and early preschool age with psychomotor disorders in comparison with the traditional system of their education.

“…( 1 ) [ 19 ] which represents the overall shaking velocity of the human body in the three axes. When analyzing static balance, ω −T1 , ω −T2 , ω −T3 , and ω −T4 were calculated as the analysis indicator by obtaining angular velocity data under different sensory conditions of T1–T4, as per existing research [ 11 ]. During the analysis of dynamic balance, the time taken to walk the balance beam was extracted, with ω as an analytical indicator.…”

“…In recent years, with the development of Micro-Electro-Mechanical Systems (MEMS), wearable sensors have gradually been applied for the detection of human balance [ 10 ]. Wearable sensors can accurately measure the static and dynamic balance of preschool children under different sensory conditions or sports states and can make up for the many defects in the “gold standard” plantar pressure test of balance [ 11 ]. The plantar pressure test evaluates human posture by collecting center of pressure (COP) data.…”

Background Balance is crucial for physical development in preschool children. Exploring the relationship between different types of balance can help understand early physical development in children. Currently, research is mostly focused on the relationship between different types of balance in the adult population and lacks exploration of the preschool population. The aim of this study explored the relationship between static and dynamic balance in preschool children aged 4 to 5 years. Methods A total of 128 preschool children between the ages of 4 to 5 years were selected. The following tests were conducted as they wore inertial sensors detecting their centers of mass (COM): T1, standing with eyes open; T2, standing with eyes closed; T3, standing with eyes open on foam; T4, standing with eyes closed on foam; and T5, walking on the balance beam. Static balance was measured by the angular velocity modulus (ω−T1–ω−T4) of the shaking COM, as well as the pitch angle (θ−T1–θ−T4) and roll angle (φ−T1–φ−T4) indicators in T1–T4 testing. Dynamic balance was measured by the time (t) and angular velocity modulus (ω−T5), as well as the pitch angle (θ−T5) and roll angle (φ−T5) indicators in the T5 test. The Pearson product-moment correlation coefficient was used to test the correlation between static and dynamic balance indicators. Results There is no correlation between ω−T1–ω−T4 and t (P > 0.05), while ω−T1–ω−T4 and ω−T5 (r = 0.19–0.27, P < 0.05) and ω−T1–ω−T4 and θ−T5, φ−T5 (r = 0.18–0.33, P < 0.05) were weakly correlated. There is no correlation between θ−T1–θ−T4, φ−T1–φ−T4 and t (P > 0.05), while θ−T1–θ−T4, φ−T1–φ−T4, and θ−T5, φ−T5 were weakly correlated (r = 0.01–0.28, P < 0.05). Conclusions The relationship between static and dynamic balance in preschool children aged 4–5 years is weak. Static and dynamic balance in children needs to be intervened separately for the development of children.

The Covid-19 pandemic has had a profound impact on various sectors worldwide, including education. This research investigates the effects of technology, communication, and administrative support on the motivation and work efficacy of business school teaching faculty engaged in online teaching during the pandemic. A structured questionnaire was distributed among 105 faculty members from business schools in Delhi, Haryana, and Uttar Pradesh. Statistical analysis techniques including KMO & Bartlett’s Test, Exploratory Factor Analysis (EFA), regression analysis, and correlation analysis were employed using IBM SPSS 26.0. The findings reveal that online platforms were highly effective for communication and teaching during the pandemic, contributing to increased motivation and work efficacy among teachers. This study provides valuable insights into the role of technology in crisis education management.
