Engineering Education of Students in the Process of Outstanding Activities

The article discusses an urgent problem for the innovative development of Russia - the orientation of schoolchildren to the choice of engineering professions through the organization of engineering education in the classroom for extracurricular activities. The authors of the article introduced and disclosed the concept of "engineering education" through the formation of cognitive interest in engineering activities. The essence of engineering education at the school stage of education and the main directions of its implementation are revealed. An important area of engineering education of students is the use of business games in the educational process of extracurricular activities. The article presents a game technology developed and implemented by the authors, which combines elements of a business game, a sports relay race and professional (engineering) tests. The structure, content and criteria for evaluating the business game-relay "Professional tests" with the aim of immersing students in specific types of educational activities, close to engineering.

Этика героя новелл Генриха фон Клейста (эволюция значений)

The key role of the ethics in the H. v. Kleist’s novellas comes from the providential character of the life’s unfolding. Having guessed it, the characters face the moral сhoice which needs to be implemented. The paradoxical uncovering of the providence as fate triggers the moral and behavioral “relay race” of characters, realizing the stages of this implementation. The historicism of the providence makes it to the dialectic of the world’s transformation with the help of the character, who had intuitively guessed this dialectics. Meanwhile, history as the social movement of the people makes moral / behavioral “relay race” of characters the stages of this movement.

The phenomenon of relay race molecular transfer of the amount of motion and its relationship with the diffusion phenomenon

The very fact of molecular transfer of the amount of motion, including in an ideal gas in an equilibrium state, has long been well known. However, this fact is still not realized as a physical phenomenon of transfer, equivalent to such transfer phenomena as diffusion, thermal conductivity and viscosity. The key concept used in this paper when describing the phenomenon of relay race molecular transfer of the amount of motion is the concept - “molecular relay race type of motion”. A molecular relay race model of an ideal gas in an equilibrium state is proposed, as well as a molecular relay race model of a mixture of two ideal gases at constant temperature and pressure. It is shown that the value of the velocity modulus of diffusion flows is one of the physical characteristics of the mixture as a whole. It is also shown that the total density of the substance carried by the diffusion flows is many orders of magnitude less than the total density of the inhomogeneous multicomponent mixture.

Activation of Porous Pt Electrodes Deposited on YSZ Electrolyte by Nitric Acid Treatment

The effect of nitric acid treatment on the electrochemical performance of porous Pt electrodes deposited on YSZ (abbreviation from yttria stabilized zirconia) electrolyte was investigated. Two identical symmetrical Pt/YSZ/Pt cells with porous Pt electrodes were fabricated, after which the electrodes of the first cell were kept as sintered, while those of the second cell were impregnated with HNO3 solution. The electrochemical behavior of the prepared electrodes was studied using impedance spectroscopy and cyclic voltammetry. Significant reduction of the polarization resistance of the HNO3-treated electrodes was revealed. The observed enhancement of the electrochemical performance of porous Pt electrodes was assumed to be caused by adsorption of NOx-species on YSZ and Pt surfaces, which promotes oxygen molecules dissociation and transport to the triple phase boundary by the “relay-race” mechanism. The obtained results allow for considering the nitric acid treatment of a porous Pt electrode as an effective way of electrode activation.

EFFECTIVE BATON EXCHANGE IN THE 4X100 M RELAY RACE

Baton exchange effectiveness and speed are essential to performance in sprint relay races, often deciding team victory. An effective baton exchange requires athletes to complete it while at full speed, both by the incoming and the outgoing athlete. Our research aimed to determine the relationship between baton exchange time and the point in the exchange zone where the handoff is completed. The study was carried out among Polish national team sprinters (n=27), competing in the 4x100 m relays. We analyzed 168 men’s and 62 women’s baton exchanges across the annual training cycle. In a 30-meter track segment corresponding to the baton exchange zone, we measured the time the baton spent in this segment (exchange time, ET), using the Brower Timing Systems (TC-System, USA), and the exact point of the baton handoff in this zone (handoff point, HP). To show the relationship between ET and HP, we performed a linear regression analysis. We have found that the further the HP the shorter the ET. This dependence is more evident in women (r=-0.66, r2=0.44 for 1st and 3rd exchanges, and r=-0.72, r2=0.52 for 2nd exchange; both P<0.001) than in men (r=-0.45, r2=0.20 and r=-0.68, r2=0.46; both P<0.001, respectively). The results suggest that the further the baton exchange takes place in the exchange zone (longer HP distance) the more effective the exchange (shorter ET). However, the coefficient of determination ranging (r2=0.20-0.52) indicates that HP explains at most 50% of the ET, and other factors should be taken into account. Nonetheless, the measuring technique proposed by us can provide coaches with additional data on baton exchange effectiveness and athletes' speed abilities.

GAME METHOD: THE DEVELOPMENT OF SPEED ABILITIES IN ATHLETES 10–12 YEARS OLD

An attempt is made to supplement and expand the understanding of the organizationof the training process of athletes (at the stage of initial training) with special means using thegame method. In a pedagogical experiment on 48 athletes (boys and girls), the effectiveness of theexperimental methodology was determined, including: blocks of outdoor games aimed at developingelementary and complex types of speed abilities; sets of conjugate development exercises (running+ jumping); relay races to prevent the formation of a “speed barrier” from hill to hill 6x40 meters, aswell as a relay race with a handicap of 4x50 meters, to increase motivation for training sessions, etc.Correlation analysis between the recorded indicators has been carried out.The effectiveness of the experimental method (p<0.05), aimed at developing the speed abilitiesof athletes of 10–12 years old, using the game method was revealed. Correlation analysis showedthat after the pedagogical experiment there was a change in the structure of correlations betweenthe studied indicators in both groups: during the training process, some connections disappeared,others appeared.Our studies allow us to assert that the use of more games for the development of speed andreaction speed will improve the results of short-distance runners without forcing special training(p<0.05).

Creativity, community and connections: Empowering people living with dementia through illustrative practice

Run Tomo is a sash relay race with people with dementia and others in their communities. From the North to the South of Japan, people run across the cities meeting others with dementia. Run Tomo actively connects people with dementia across Japan. The project challenges the stigma of dementia, showing what is possible with a diagnosis, both to the participants and the wider communities, making the cities more dementia-friendly and aware. In September and October 2019, Ellie ran with the individuals, inviting them to document their shared experiences by using The Photobook Project model. By selecting themes, participants of Run Tomo took photographs using single-use cameras. Mirroring the movement of the sash, being passed between participants, the cameras captured the smiles, places, movement, weather and challenges they encountered. The project captures the phenomenological experience of place: from the sweaty foreheads, to when hands meet, to the tender moments where people celebrate their athletic achievements. The Photobook Project features in a wider context of Ellie’s research about the role illustration plays in creating new channels of communication, methods of engagement and illumination of narrative for people living with dementia. This article asserts the power of illustration within a socially engaged context, in particular those living with dementia and their carers, making the case for experiential illustration as a tool for empowerment and connection.
