Abstract. In two pilot experiments, a new approach for the direct assessment of cognitive load during multimedia learning was tested that uses dual-task methodology. Using this approach, we obtained the same pattern of cognitive load as predicted by cognitive load theory when applied to multimedia learning: The audiovisual presentation of text-based and picture-based learning materials induced less cognitive load than the visual-only presentation of the same material. The findings confirm the utility of dual-task methodology as a promising approach for the assessment of cognitive load induced by complex multimedia learning systems.

In this article, we present a taxonomy in Robot-Assisted Training; a growing body of research in Human–Robot Interaction which focuses on how robotic agents and devices can be used to enhance user’s performance during a cognitive or physical training task. Robot-Assisted Training systems have been successfully deployed to enhance the effects of a training session in various contexts, i.e., rehabilitation systems, educational environments, vocational settings, etc. The proposed taxonomy suggests a set of categories and parameters that can be used to characterize such systems, considering the current research trends and needs for the design, development and evaluation of Robot-Assisted Training systems. To this end, we review recent works and applications in Robot-Assisted Training systems, as well as related taxonomies in Human–Robot Interaction. The goal is to identify and discuss open challenges, highlighting the different aspects of a Robot-Assisted Training system, considering both robot perception and behavior control.

Abstract: The objective of this work was to compare the effect of the Y-trellis and vertical shoot position trellis (VSP) training systems on the physicochemical composition and aromatic profile of 'Sauvignon Blanc' (Vitis vinifera) wines in a high-altitude region of the state of Santa Catarina, Southern Brazil. The experiment was conducted during the 2015 vintage in a commercial vineyard located in the municipality of São Joaquim. The treatments consisted of the training systems: Y-trellis and VSP pruned in spur cordon. Sixty kilograms of grapes were harvested from each training system to make the wines, which were evaluated as to their chemical and phenolic composition and aromatic profile. There is no effect of the training system on the wine chemical variables pH, total acidity, color, and total polyphenols. The aromatic profile and phenolic composition of the wines are affected by the training systems, being related to the variables ethyl acetate, isoamyl acetate, 3-methyl-1-butanol, propanoic acid, and gallic acid in the Y-trellis, and to 1-hexanol, isovaleric acid, caprylic acid, capric acid, and catechin in VSP. The Y-trellis system can be an alternative for high-altitude regions of Southern Brazil.

Psychological and behavioral evidence suggests that home sports activity reduces negative moods and anxiety during lockdown days of COVID-19. Low-cost, nonintrusive, and privacy-preserving smart virtual-coach Table Tennis training assistance could help to stay active and healthy at home. In this paper, a study was performed to develop a Forehand stroke’ performance evaluation system as the second principal component of the virtual-coach Table Tennis shadow-play training system. This study was conducted to show the effectiveness of the proposed LSTM model, compared with 2DCNN and RBF-SVR time-series analysis and machine learning methods, in evaluating the Table Tennis Forehand shadow-play sensory data provided by the authors. The data was generated, comprising 16 players’ Forehand strokes racket’s movement and orientation measurements; besides, the strokes’ evaluation scores were assigned by the three coaches. The authors investigated the ML models’ behaviors changed by the hyperparameters values. The experimental results of the weighted average of RMSE revealed that the modified LSTM models achieved 33.79% and 4.24% estimation error lower than 2DCNN and RBF-SVR, respectively. However, the R ¯ 2 results show that all nonlinear regression models are fit enough on the observed data. The modified LSTM is the most powerful regression method among all the three Forehand types in the current study.

Digital technologies command determines the information and professional competence of a teacher. The first competences help him to organize a modern educational process, others provide access to the latest professional information. Studies show that serious complex strategies for the use of digital technologies are beginning to emerge, and a teacher is becoming a leader in future education. Digital technologies are becoming more complicated and there is an urgent need for new professionals - learning engineers who have to provide new strategies in education. The paper considers a complex of open distance courses for the training of teachers to use new educational technologies. The courses use the results of the annual polls of the world's pedagogical community to identify popular pedagogical instruments. They form teachers’ personal knowledge mastery. This contributes to the development of a personal learning environment and a teacher's personal learning network. The learning engineer's training system should consist of software engineering and the proposed teaching block. The last block includes sections for the formation of skills of personal knowledge mastery, the design of a distance course, the development of the structure, organization of distance and blended learning, expertise of the distance course. All sections of the pedagogical unit were tested in open distance courses at the Research Laboratory of Distance Learning at NTU "KhPI". During 2013-2018 open distance learning courses were learnt by more than 2,600 teachers of Ukraine and 370 of them successfully completed the training. The next step should be to integrate efforts with IT specialists, identify competencies of the learning engineer and prepare a training program for a specialist in the future.

The aim of this study was to evaluate phenology aspect, vigor, production and quality of ‘Eragil’ peach trees grown under different training and pruning systems. Evaluations were carried out during two seasons, 2015/16 and 2016/17. Fruit tree training and pruning systems ‘Open Center’ (3.5 × 5.0 m), ‘Ipsilon’ (1.5 × 5.0 m) and ‘Central Leader’ (0.8 × 5.0 m) were used. Phenology, vegetative growth (vigor) and yield were evaluated. ‘Central Leader’ plants showed a higher productivity and productive efficiency. ‘Open Center’ plants had a greater vigor and yield per plant, however had a lower yield by unit area. Plants with ‘Y’ shape were intermediates between ‘Open Center’ and ‘Central Leader’ in relation of the evaluated variables. ‘Central Leader’ training system can be used for peach orchards in order to increase yield and productivity indexes.

Four interspecific grape hybrids (Vitis spp.) developed in Arkansas were evaluated for primary bud hardiness by differential thermal analysis. Buds from two locations were analyzed over 2 years for acclimation, midwinter hardiness, and deacclimation. In addition, effects of two training systems on cold hardiness of buds were evaluated in one location. The buds of the two genotypes with the greatest component of V. vinifera in their ancestry acclimated more slowly than did the other genotypes. Ultimate midwinter bud hardiness was greater in the genotypes possessing less V. vinifera than other parentage. No effect on cold hardiness due to training system was noted. No natural winter freeze damage was observed on any of the genotypes in the period of observation.
