Comfort Evaluation of Slow-Recovery Ejection Seat Cushions Based on Sitting Pressure Distribution

Sitting discomfort not only affects the health of pilots carrying out long-endurance missions but also affects operational performance. The experimental objects included four ejection seat cushions: N1 was a fast-recovery foam as the comparison group, and the experimental groups were slow-recovery foams with different indentation force deflection (IFD), named N2 (hard), N3 (mid), and N4 (soft). The sitting comfort of 20 participants was tested on the four cushions by using subjective rating and sitting pressure distribution analysis. The results showed that compared with fast-recovery cushion N3 and N4 slow-recovery cushions have lower contact pressure and more uniform pressure distribution. Slow-recovery cushions that were too soft or too hard would reduce the comfort. No matter from the subjective rating or the analysis of the contact pressure data, the N3 cushion with a thickness of 3 cm and 65% IFD of 280 N had the highest comfort. In addition, the seat pressure distribution (SPD%) has a significant correlation with the subjective rating (p = 0.019, R = −0.98), which is more suitable for evaluating the comfort of the cushions. However, the slow-recovery cushions would show a decrease in support after a period of sitting, while the fast-recovery cushion could always maintain constant support.

Study on Surrounding Rock Structure Evolution Characteristics and Roof Control Techniques of the Retained Roadway Formed by Roof Cutting in Inclined Coal Seams

To control the roof during gob-side entry retaining by roof cutting in inclined coal seams, the retained gob-side roadway is zoned based on the mechanical principle and technological process of no-pillar mining with gob-entry retention. A simplified mechanical model for surrounding rocks in different subzones was established by using theoretical analysis and numerical simulation to attain the demand for the support resistance and deformation of the roof in different subzones. According to load and deformation characteristics of the roof and mechanical characteristics of NPR cables, single props, and a sliding-type gangue-retaining structure formed by U-shaped steel inserts, the supporting systems for roadways in different subzones and the constitutive model thereof were established. On this basis, the action of the supporting system was analysed and a field test was performed. The results show that the supporting system undergoes three stages of behaviour, i.e., pressure growth, yielding under constant pressure, and stabilisation during whole entry retention. It can guarantee the collaborative deformation of the supporting systems with the roof on the premise of constant support resistance, thus satisfying the requirement for roadway protection. The roadway 150 m back from the working face is stable, and the final convergence between the roof and floor of the retained entry is 257 mm, showing a favourable entry-retention effect.

Working Remotely During the COVID-19 Pandemic: Efforts of the Ministry of Education in the United Arab Emirates

Following the global outbreak of COVID-19 pandemic, work is no longer being conducted in the traditional manner. This has created pressure on businesses to shift into a mode of remote working in order to avoid severe disruption. The United Arab Emirates (UAE) has attempted to face challenges accompanying this crisis and explore solutions with the wise vision and constant support of its leadership. This paper examines the transition of working procedures at one of the most influential entities in the UAE; the Ministry of Education (MOE). The purpose here is to shed light on how obstacles have been turned into opportunities in order for MOE employees to continue working remotely during such critical conditions. This is illustrated by the efforts of ministry departments that were interviewed for their feedback during the study. This paper provides insights into the activation of remote work in response to sudden incidents by highlighting measurements and factors that contribute to entities’ readiness for such a transition. This study analyzes the value and originality of MOE remote working practices and their impact on the wider community.

Development of knowledge-based resources in Ukraine

The article considers the concept of open science. The brief overview of different approaches to its interpretation is provided, the components and principles of implementation are given. One of the key elements of open science is an open scientific infrastructure, in particular — knowledge-based resources – scientific archives, platforms, repositories. Without proper attention from the scientific and educational community, as well as the state, it is impossible to ensure their proper development. After all, any infrastructure requires constant support aimed at ensuring the proper functioning and modernization in accordance with world best practices. In this regard, Ukraine needs political solutions that support the establishment of open science. They, in its turn, should be implemented through a project approach to individual infrastructure (including the National Repository of Academic Texts) and through the introduction of a common framework, standard guidelines, proven approaches, and established practices that can be scaled within the state, extended to institutions of scientific and educational sphere. The article examines in detail the project of creating a National Repository, as well as identifies promising areas for its development.

Is planting trees good or bad?

Planting trees is popular, widely accepted and supported, resulting with many initiatives and commitments around the globe. At the same time, planting trees is questioned more and more and receive a lot of criticism. In this paper we consider the arguments of both sides and discuss them using a scientific evidence. Determination of restoration opportunities and restoration needs requires more intention to existing ecosystems and their use. Commitments and expectations need to be realistic to maintain constant support based on real results. Planting trees is not the best solution for carbon storage, but it is one of the best solutions available at this moment. Even if reduce anthropogenic CO2 emission to zero, we will need to plant trees. Planting trees can have both negative and positive effect on water availability and socio-economy, depending on restoration practice applied. Planting trees is definitely good, if it is done at appropriate site and with appropriate tree species and if it is based on proper planning and realistic expectations.

Formation of Students' Motivation for Physical Culture and Sports

The article is devoted to the study of approaches and ways of forming students' motives for physical culture and sports. The purpose of the article is to study the interest of students in physical culture and sports by studying new methods of physical activity. The tasks of new research are to create conditions for the formation of a conscious need for physical exercises, increase the level of non-special physical education, and improve the socio-cultural status of student youth. The process of forming an interest in physical culture and sports is complex in structure, it cannot be carried out quickly: from the first simplest knowledge and skills in the field of hygiene to deep psychophysiological knowledge of the theory and methodology of education and intensive sports. The system of physical development in a higher educational institution of vocational education forms the student's physical culture, in the appearance of his integral as a normal quality, as a condition for scientific and professional activity, as a generalized indicator of the culture of a future specialist and as the goal of self-improvement and self-development. Constant support of the educational motivation of students will allow them to consciously assimilate the knowledge provided, to form skills and abilities; a useful attitude to teaching physical education and involvement in systematic exercise and sports. The effectiveness of physical education will increase significantly if an algorithm is developed to involve pupils, students, and the population in regular physical culture and sports in real socio-economic conditions. It is necessary to seriously pay attention to the problem of physical education of children and youth, because they are two age categories that represent the entire human race, which will transfer knowledge obtained all their lives to future generations.
