Algorithmic Study on Position and Movement Method of Badminton Doubles

The algorithms used by schedulers depend on the complexity of the schedule and constraints for each problem. The position and movement of badminton players in badminton doubles competition is one of the key factors to improve the athletes’ transition efficiency of offense and defense and the rate of winning matches and to save energy consumption. From the perspective of basic theory, the author conducts research on the position and movement of badminton doubles. Based on the numerical analysis method, the optimal model of standing position and direction composed of 7 nonlinear equations is established. In addition, the final of 10 matches of the super series of the world badminton federation in 2019 was selected as the sample of speed parameters. With the help of MATLAB mathematical analysis software, the numerical model established by the least square method was adopted to optimize the specific standing position and walking model. Ultimately, the optimal solution has been obtained, which can be represented on a plane graph. The optimal position of the attack station should be the blocking area (saddle-shaped area) and the hanging area (circular arc area in the middle). The optimal defensive positioning should be left defensive positioning area (left front triangle area) and right defensive positioning area (right front triangle area), which is consistent with our current experience and research results. The research results use mathematical tools to calculate the accurate optimal position in doubles matches, which has guiding significance to the choice of athletes’ position and walking position in actual combat and can also be used as a reference for training, providing a certain theoretical basis for the standing and walking of badminton doubles confrontation. The data collection and operation methods in this study can provide better calculation materials for artificial intelligence optimization and fuzzy operation of motion displacement, which is of great significance in the field of motion, simulation, and the call of parametric functions.

The historical significance of the ARMU during the NEP and Ukrainization

The article examines the circumstances of the founding of the Association of Revolutionary Art of Ukraine (ARMU), its program principles and significance in the history of Ukrainian art in the second half of the 1920s — early 1930s. The cultural and political reasons and consequences of the introduction of the NEP, Ukrainization, collectivization and reform of art education in the Ukrainian SSR, as well as the changes that took place after the transfer of power in the USSR from V. Lenin to J. Stalin were analyzed. It was found that the ARMU was founded against the background of intensifying competition between left and right wings of art, as well as the emergence of branches of the Russian associations AHRR (Association of Artists of Revolutionary Russia) and LEF (Left Front of Art) in the Ukrainian SSR. It is shown how the connection of the ARMU with the Kyiv Art Institute (KKhI), its rector, teachers and students influenced the formation of a broad program of this association, which proclaimed the equality of all types of fine arts and design. It is analyzed how the resolutions of the Communist Party and the peculiarities of cultural policy in the field of fine arts in the Ukrainian SSR during the time of O. Shumsky and M. Skrypnyk influenced the activities of art associations and the ARMU in particular. The statements of the ideologists of the ARMU I. Vrona and V. Sedlyar about the realism and activity of the Russian association of the AKhRR in the Ukrainian SSR are analyzed. The consequences of the collapse of the NEP and Ukrainization, with the fight against formalism on the fate of the ARMU and its members were revealed.

Spatial and semantic interference on an auditory Stroop test: comparison of young and older adults

Background and Aim: Age related changes in cognitive functioning have been shown to vary depending on the task used. Thus, the study aimed to compare the responses of young and older adults to an auditory Stroop test that asse­ssed spatial (responses to location of the stimuli) and semantic (responses to meaning of the sti­muli) localization. Methods: The “Auditory spatial and semantic localization Stroop test”, developed as a part of the study was administered on 30 young adults aged 18 to 30 years and 30 older adults aged 58 to 70 years having normal hearing. The res­ponse accuracy and reaction time of the parti­cipants were determined for the words “right”, “left”, “front”, and “back.” Results: The older adults had significantly poo­rer response accuracy and reaction time than the young adults for both spatial and semantic loca­lization tasks. Within each participant group, semantic localization had better response accu­racy than spatial localization, while such diffe­rences in reaction time were found only in the older adults. In both groups, a congruency effect was seen for spatial but not for semantic loca­lization when response accuracy was calculated, whereas it was observed only for semantic and not for spatial localization when reaction time was measured. Conclusion: The auditory Stroop test, which measures stimulus interference and cognitive skills, could be used as a simple tool to assess the same for stimuli presented through the audi­tory modality. This would be especially helpful in older adults who may demonstrate cognitive decline with ageing to auditory stimuli. Keywords: Spatial localization; semantic localization; auditory Stroop test; age related changes

Context

Chapter 2 provides a detailed account of the three key stories of change that form the backdrop to this study—in paddy cultivation, electoral politics, and the practice of Islam. The two villages of Madanpur and Chishti (pseudonyms) are described. The changing dynamics of paddy cultivation and the challenges of the Green Revolution are introduced, as are the basic programs of land reform undertaken by communist governments. The story of huge electoral change from near-complete dominance of the communist parties of the Left Front from 1977 to their rout by Trinamool Congress in 2013 thirty four years later is outlined. The particular story of Islam, the origin of the elite Syeds from an Iranian ancestor, and present-day dynamics with reformist Islam are presented. Charles Taylor’s idea of “social imaginaries”—a key concept in the book—is discussed here.

Concept Analysis of the Tarbiyatul Aulād Fī Al-Islām Abdullah Nashih Ulwan

This study aims to explain the concept of children's social education responsibility from the perspective of Abdullah Nashih Ulwan, which is focused on analyzing the material by paying attention to the rights of others to form children's independent character. This type of research is non-interactive qualitative with a concept analysis approach. The results showed that there are six concepts of children's social education responsibility in paying attention to the rights of others to form an independent character according to Abdullah Nasih Ulwan. First, the rights of both parents, namely to introduce the rights of both parents to their children by being filial to them. Second, sibling rights, namely the rights of people who have lineage or kinship. Third, the right of neighbours, namely all people next to their house on the right, left front, and back, about forty houses. Fourth, the teacher's right, namely to educate children to respect the teacher, be reluctant to him, and fulfil the teacher's rights. Fifth, the rights of friends, namely choosing friends who are faithful and pious for their children. Sixth, the rights of older people, namely the rights of people who are older, have more knowledge, have higher piety and religion, and are more dignified, noble and have status.

Impacts of Human Robot Proxemics on Human Concentration-Training Games with Humanoid Robots

The use of humanoid robots within a therapeutic role, that is, helping individuals with social disorders, is an emerging field, but it remains unexplored in terms of concentration training. To seamlessly integrate humanoid robots into concentration games, an investigation into the impacts of human robot interactive proxemics on concentration-training games is particularly important. In the case of an epidemic diffusion especially—for example, during the COVID-19 pandemic—HRI games may help in the therapeutic phase, significantly reducing the risk of contagion. In this paper, concentration games were designed by action imitation involving 120 participants to verify the hypothesis. Action-imitation accuracy, the assessment of emotional expression, and a questionnaire were compared with analysis of variance (ANOVA). Experimental results showed that a 2 m distance and left-front orientation for a human and a robot are optimal for human robot interactive concentration training. In addition, females worked better than males did in HRI imitation games. This work supports some valuable suggestions for the development of HRI concentration-training technology, involving the designs of friendlier and more useful robots, and HRI game scenarios.

Beyond Conspiracy and Coordinated Ascendancy: Revisiting Caste Question in West Bengal under the Left Front Rule (1977–2011)

This article has critically engaged with the speculative claim that the disappearance of caste question from public discourse during Left rule in West Bengal was a result of conscious upper-caste ploy to silence articulation of caste interests and tactfully eliminate the possibility of Dalit political assertion. To verify the veracity of this claim, this study has critically scrutinized Left Front’s political mobilization strategy of rural population and also its landmark land reform initiative. The investigation attempted by this article, in this regard, has revealed that there is little to suggest the existence of any organized upper-caste conspiracy. It is, however, true that the articulation and aggregation of political demands along the lines of caste was indeed averted in West Bengal through political tactics and developmental strategies devised by the upper castes. But, the marginalization of the caste question in mainstream politics was an unintended consequence of such political tactics and developmental strategies which were primarily designed with the objective to preserve and enlarge the political support base, rather than to contain the lower castes. Thus, political motives acted as far more important determinants of political and developmental activities rather than any inherent caste bias.

Sebaceous Adenoma on the Toe of a Dog at an Animal Hospital in Thonburi Area, Bangkok Province, Thailand

A 7-year-old dog, Shih Tzu breed, intact male, came to an animal hospital in Thonburi area, Bangkok Province, Thailand with symptom of licking the left forefoot. Small lumps about 1×1×1cm (w×l×h) were found to be protruding around the left front toe. Surgical excision to remove the mass and subsequent histological examination identified the mass as sebaceous adenoma. After surgery and follow-up at 12 months, there were no obvious complications. Reports of this type concerning tumors in the paws tend to be rare. Furthermore, reports of tumor findings in this area remain unclear.
