Authors: Marchenko S. , Golenkova Yu. , Putnina Yu. 
Published: November 2023

Physical education classes in modern Ukrainian schools play a crucial role in ensuring students' physical development and health, as well as in shaping their overall physical and sports awareness. Contemporary trends in education facilitate the exploration of new forms and means of conducting physical education classes and the enhancement of existing ones. The purpose of this article is to investigate the development dynamics of coordination abilities in middle school students when using mobile games with objects during physical education lessons.
Mobile games are an essential component of student's physical development and can serve as a means of relieving stress while effectively enhancing physical qualities. The use of not only standard equipment (balls, gymnastic sticks, jump ropes, hoops) but also non-traditional items (air balloons, boards, etc.) adds emotional depth to the lessons and increases interest in physical education. The research conducted revealed a positive shift in coordination ability indicators for both boys and girls as a result of using mobile games with objects during physical education classes.
In boys, the likely improvements were observed in the ability to assess and regulate spatial-temporal and dynamic parameters of movement (p<0,05), the ability to maintain vestibular stability (p<0,05), the ability to maintain balance (p<0,001), movement coordination ability (p<0,001), and rhythmic activity ability (p<0,001).
For girls in the experimental group, coordination ability indicators exhibited likely improvements in differentiating spatial- temporal parameters of movement (p<0,05), the ability to maintain vestibular stability (p<0,01), the ability to maintain balance (p<0,001), movement coordination ability (p<0,001), and rhythmic activity ability (p<0,001).
In conclusion, the use of mobile games with objects during physical education classes for middle school students contributes to the development of their coordination abilities.

Background: Exposure to stress early in life increases the susceptibility to Alzheimer’s disease (AD) pathology in aged AD mouse models. So far, the underlying mechanisms have remained elusive. Objective: To investigate 1) effects of early life stress (ELS) on early functional signs that precede the advanced neuropathological changes, and 2) correlate synaptosomal protein content with cognition to identify neural correlates of AD. Methods: APPswe/PS1dE9 mice and littermates were subjected to ELS by housing dams and pups with limited bedding and nesting material from postnatal days 2-9. At 3 months of age, an age where no cognitive loss or amyloid-β (Aβ) pathology is typically reported in this model, we assessed hippocampal Aβ pathology, synaptic strength and synapse composition and interneuron populations. Moreover, cognitive flexibility was assessed and correlated with synaptosomal protein content. Results: While ELS did not affect Aβ pathology, it increased synaptic strength and decreased the number of calretinin+ interneurons in the hippocampal dentate gyrus. Both genotype and condition further affected the level of postsynaptic glutamatergic protein content. Finally, APP/PS1 mice were significantly impaired in cognitive flexibility at 3 months of age, and ELS exacerbated this impairment, but only at relatively high learning criteria. Conclusions: ELS reduced cognitive flexibility in young APP/PS1 mice and altered markers for synapse and network function. These findings at an early disease stage provide novel insights in AD etiology and in how ELS could increase AD susceptibility.

BACKGROUND: Mulberry ( Morus) from the Moraceae family is distributed widely in tropical to temperate regions of the world having economic and medicinal significance with exceptional nutritional characteristics. OBJECTIVES: Assessment of variations in sugars, acidity, minerals, total phenolics, anthocyanins and antioxidant potentials of three black mulberry ( Morrus serrata, M. nigra and M. macroura black) and two white mulberry cultivars ( M. alba and M. macroura white) during development stages. METHODS: Total sugars and acidity were evaluated with AOAC methods and total phenolic content was estimated with folin-ciocalteau method. Antioxidant activity was evaluated with DPPH assay, minerals were quantified with atomic absorption spectroscopy and anthocyanins were assessed and identified with high performance liquid chromatography and liquid chromatography-mass spectroscopy. RESULTS: Over all, M. alba (white cultivar) displayed maximum sugar (1.35%) at fruit development stage 3 (FDS-3) following M. serrata (black cultivar) at FDS-5 (1.1%) and M. macroura white (white cultivar) at FDS-4 (0.9%). Acidity decreased in M. alba (0.8–0.09%), M. nigra (0.8–0.03%) and M. macroura white (0.6–0.04%) during development. Total phenolic content was maximum (590 GAE/100 g) in M. nigra at FDS-6 and M. serrata (450 GAE/100 g) at FDS-7. Two black cultivars ( M. serrata and M. nigra) showed significant increase in total anthocyanins (14.57–100.06 and 14.13–201.87 CGE/100 g FW) from FDS-1 to FDS-7 while decrease in M. macroura black and M. macroura white (17.07–11.79 and 9.03–2.68) from FDS-1 to FDS-7. The DPPH inhibition of black mulberries was pointedly greater with significant levels of iron, copper, zinc, calcium, magnesium, sodium, phosphorus and potassium than white cultivars during maturity. HPLC and LC-MS procedures identified various anthocyanins in all cultivars including cyanidin, malvidin, pelargonidin and delphinidin. CONCLUSIONS: Mulberries with improved nutrition, acceptable range of metals, bioactive compounds and higher antioxidant potentials could be significant against various diseases like cancer, cardiovascular problems, neurodegenerative disorders, obesity, diabetes and other metabolic syndromes.

¿Reparar las injusticias del pasado o sanar nuestra conciencia? Perspectiva jurídico-ética sobre los motivos de restitución de objetos culturales de época colonial
Authors: Nevado Viñarás Cristina 
Published: November 2023

La restitución de bienes culturales no es un fenómeno aislado que se pueda abordar desde una sola dimensión. Las estrechas relaciones que establece con diversos sectores y áreas de conocimiento (antropología, economía, turismo, filosofía, etc.) lo convierten en un elemento complejo. Los cambios sociales y políticos de las últimas décadas, que han ganado importancia en los últimos años, e incluso meses, nos permiten hablar de un ámbito de estudio relativamente nuevo en la esfera social, jurídica y política.
Este artículo aporta una perspectiva jurídica sobre la restitución de objetos culturales que fueron extraídos de sus lugares de origen durante época colonial o a consecuencia de las dinámicas de la misma. Pretende plantear cuestiones acerca del punto de partida jurídico-ético en materia de restitución y reflexionar acerca de los motivos de restitución.
Asimismo, considera las dificultades desde un punto de vista jurídico en la restitución de objetos culturales e invita al lector a reflexionar sobre las razones morales de la restitución.

Published: November 2023

In a coffee processing production process, roasted coffee beans can now be ground using a motor-driven grinder. For an industrial scale, a Disc Mill typecoffee bean grinder is generally needed because it is able to get coffee grounds faster and smoother than other types. However, a Disc Mill typecoffee bean grinder has a disadvantage if the grinding load increases, it will affect the rotational speed of the motor so that there is the potential for congestion in the Disc Mill blade. Therefore, a control method is needed to maintain the speed stability of the induction motor. The control method used is Proportional-Integral(PI). To obtain the exact value of the parameter used the Ziegler-Nichols method of oscillations. The PI controller using the Ziegler-Nichols method is considered capable of obtaining a relatively stable system response and get a shorter reference value. System testing with tuning values Kp = 0.108 and Ki = 0.13 was carried out at a speed of 1400rpm. A stable system response was obtained with a rise time of 4 seconds, a settling time of 5 seconds, a peak time of 9s, a maximum overshoot of 2.85% and a steady state error of 0.89%. With the application of the PI method, the Disc Mill type coffee bean grinding motor can maintain the stability of the rotational speed compared to without control.
A preliminary model of the mangrove ecosystem of Dongzhaigang Bay, Hainan, (China) based on Ecopath and Ecospace

Published: November 2023

IntroductionMarine and coastal ecosystems are complex, especially because of the connection between their many functional groups and the various habitats provided by subsystems.MethodTo describe the trophic interactions, energy flows, and spatial distribution of species in the ecosystem of Dongzhaigang Bay, in Hainan, China, 28 functional groups were identified, incorporated in Ecopath and Ecospace models, and used to derive the particle size and spatial distribution of the functional groups.ResultThe results show that the trophic levels of top predators are lower than in similar ecosystems, but that the ecosystem of Dongzhaigang Bay exhibits a high ecotrophic efficiency, leading to a high fraction of its primary and secondary production being transferred to the higher trophic levels. The particle size distribution (PSD; i.e., log(biomass) vs log(particle weight)) in Dongzhaigang Bay, the first estimated for any mangrove ecosystem, has a slope (-0.80) similar to that of other ecosystems along China’s coast , but does not include the largest size groups. Ecospace allowed a visualization of the functional groups in Dongzhaigang Bay, which can serve as a basis, e.g., for identifying areas requiring special protection.DiscussionThough the status of the bay, overall, appears to be better than many of the Chinese coastal ecosystems, further monitoring and data collection are required to deepen the understanding of the interactions within the ecosystems, and the impacts of human activities on Dongzhaigang Bay. The models presented here should help in this undertaking.
