Construction and Simulation of Athlete’s Wrong Action Recognition Model in Sports Training Based on Embedded Wireless Communication and Computer Vision

Embedded networking has a broad prospect. Because of the Internet and the rapid development of PC skills, computer vision technology has a wide range of applications in many fields, especially the importance of identifying wrong movements in sports training. To study the computer vision technology to identify the wrong movement of athletes in sports training, in this paper, a hidden Markov model based on computer vision technology is constructed to collect video and identify the landing and take-off movements and badminton serving movements of a team of athletes under the condition of sports training, Bayesian classification algorithm to analyze the acquired sports training action data, obtain the error frequency, and the number of errors of the landing jump action, and the three characteristic data of the displacement, velocity, and acceleration of the body’s center of gravity of the athlete in the two cases of successful and incorrect badminton serve actions and compared and analyzed the accuracy of the action recognition method used in this article, the action recognition method based on deep learning and the action recognition method based on EMG signal under 30 experiments. The training process of deep learning is specifically split into two stages: 1st, a monolayer neuron is built layer by layer so that the network is trained one layer at a time; when all layers are fully trained, a tuning is performed using a wake-sleep operation. The final result shows that the frequency of the wrong actions of the athletes on the landing jump is concentrated in the knee valgus, the total frequency of error has reached 58%, and the frequency of personal error has reached 45%; the problem of the landing distance of the two feet of the team athletes also appeared more frequently, the total frequency reached 50%, and the personal frequency reached 30%. Therefore, athletes should pay more attention to the problems of knee valgus and the distance between feet when performing landing jumps; the difference in the displacement, speed, and acceleration of the body’s center of gravity during the badminton serve will affect the error of the action. And the action recognition method used in this study has certain advantages compared with the other two action recognition methods, and the accuracy of action recognition is higher.

Climatology of Frequency, Life Period, Energy and Speed for Tropical Disturbances and Cyclones over the Bay of Bengal

Tropical disturbances and cyclones are regularly formed at the Bay of Bengal basin. There are some common traits in them, albeit each one of them is unique. Discerning climatology for the basic features of any tropical cyclone is useful in numerous ways. This research has attempted to find a climatology for frequency, life period, energy, and speed for the tropical cyclones formed at the Bay of Bengal over a period of 31 years – from 1990 to 2020. The results elicit that there are marked changes in these aforementioned features. The total frequency, accumulated duration, and combined energy have escalated over the years. To be precise, these changes have taken effect more rigorously for the Post-monsoonal tropical cyclones. The overall translational speed has slightly diminished in recent years, except for the translational speed of cyclones formed during Pre-monsoon. These changes will have major ramifications on the lives and livelihoods of people, more so for those living in coastal areas. Hence, necessary actions are required to cut the probable losses and damages. The Dhaka University Journal of Earth and Environmental Sciences, Vol. 10(1), 2021, P 23-31

The Use of Non-Verbal Communication in Supporting the Realization of Brown & Levinson Politeness Strategies

One of the prominent issues in pragmatics is politeness. Politeness can manifest in two actions, verbal and non-verbal communication. This study aimed to analyze the lecturer's and the students' non-verbal communication (NVC) in supporting the realization of Brown & Levinson's politeness strategies in English classroom interaction at Universitas Muhammadiyah Purworejo. This study explains the lecturer’s and students’ NVC in supporting the realization of bald on record strategy, positive politeness strategy, negative politeness strategy, off-record strategy, and don’t do the face-threatening act (FTA) strategy in English classroom interaction. In this study, the researchers applied qualitative research. The subjects were one English lecturer and students. The objects were the lecturer's and the students' utterances during the English learning process. The methods the researchers used to analyze the data were Brown & Levinson's (1987) politeness strategies theory and Novinger's (2001) NVC theory. The findings showed that politeness strategies were used by the lecturer and students with the total frequency of 559 times, namely bald on record, positive politeness (dominantly used), negative politeness, off-record, and don’t do the FTA (the least used). Besides, in supporting the realization of politeness strategy, the dominantly used methods of NVC were chronemics, kinesics, and vocalic. In conclusion, politeness strategies are crucial in maintaining the relationship and creating a comfortable environment in the EFL classroom. NVC can support performance that cannot be expressed in words.

JUSTIFICATION OF THE TECHNOLOGICAL PARAMETERS OF THE BELT DEVELOPED BY THE MANIPULATOR LOGGING MACHINE FOR SELECTIVE LOGGING, TAKING INTO ACCOUNT AVAILABILITY

Рассмотрена возможность реализации проходных рубок в сосняка 40, 60 и 80 лет валочно-пакетирующей машиной (ВПМ) с грузонесущим манипулятором типа ЛП-19. Рассмотрена возможность изреживания нормальных древостоев ВПМ на 20 %. Обеспечение доступности деревьев, назначенных в рубку, и возможность их беспрепятственного выноса к месту укладки достигаются за счет сокращения расстояния между рабочими стоянками и сокращения ширины разрабатываемой ленты. При сокращении расстояния между стоянками увеличивается кратность обработки отдельных участков полулент, а сокращение ширины разрабатываемой ленты за счет наиболее удаленных ее зон с наименьшей кратностью обработки увеличивает общую кратность обработки полулент и, соответственно, доступность деревьев, отведенных в рубку. Приведены значения расстояний между рабочими позициями и ширины лент, обеспечивающие достаточную доступность деревьев, назначенных в рубку, по всей площади разрабатываемой ленты для рассматриваемых древостоев. The article discusses the possibility of implementation of cross-cutting felling in a pine forest of 40, 60 and 80 years old feller-buncher (VPM) with a load-carrying manipulator of the LP-19 type. The possibility of thinning normal IPM stands by 20 % is considered. Ensuring the accessibility of trees assigned to the felling and the possibility of their unimpeded removal to the place of laying is achieved by reducing the distance between working stations and reducing the width of the belt being developed. With a reduction in the distance between sites, the frequency of processing of individual sections of semi-belts increases, and a reduction in the width of the belt being developed due to its most remote zones with the lowest frequency of processing increases the total frequency of processing of half-belts and, accordingly, the availability of trees allocated to the felling. The values of the distances between the working positions and the width of the bands are given, which ensure suffi cient accessibility of the trees assigned to the felling over the entire area of the belt being developed for the stands under consideration.

Συγκριτική μελέτη των διαταραχών σίτισης και των παραγόντων κινδύνου σε παιδιά προσχολικής ηλικίας υγιή και με παθήσεις του πεπτικού συστήματος

Εισαγωγή: οι διαταραχές σίτισης είναι συχνές στην παιδική ηλικία. Σύμφωνα με τη βιβλιογραφία το 25%-45% των παιδιών τυπικής ανάπτυξης αντιμετωπίζουν προβλήματα σίτισης. Τα παιδιά με παθήσεις του πεπτικού συστήματος θεωρούνται ομάδα υψηλού κινδύνου για εκδήλωση τέτοιων προβλημάτων. Σκοπός της παρούσας μελέτης ήταν η διερεύνηση του επιπολασμού και των χαρακτηριστικών των προβλημάτων σίτισης σε υγιή παιδιά τυπικής ανάπτυξης και σε παιδιά με προβλήματα του πεπτικού συστήματος, ηλικίας 2-7 ετών, στην Ελλάδα. Στα πλαίσια της μελέτης αυτής διερευνήθηκαν παράγοντες που πιθανά σχετίζονται με την εμφάνιση διαταραχών σίτισης στις δύο ομάδες παιδιών, όπως τα δημογραφικά χαρακτηριστικά των παιδιών και των γονέων, το ιστορικό σίτισης βρεφικής ηλικίας και τα αναπτυξιακά στάδια σίτισης του παιδιού, το περιβάλλον σίτισης και οι γονικές πρακτικές σίτισης. Μέθοδος: μελέτη παρατήρησης χρονικής στιγμής, τύπου ασθενών και μαρτύρων. Μετά την εφαρμογή των κριτηρίων επιλογής και αποκλεισμού στη μελέτη συμπεριλήφθηκαν 928 παιδιά (787 στην ομάδα ελέγχου και 141 στην κλινική ομάδα). Για τα παιδιά αυτά συλλέχθηκαν πληροφορίες που αφορούν τα δημογραφικά και ανθρωπομετρικά στοιχεία, τη συμπεριφορά κατά τη σίτιση, το ιατρικό ιστορικό, το ιστορικό σίτισης, το περιβάλλον σίτισης και τις γονικές πρακτικές σίτισης. Αποτελέσματα: Στην ομάδα ελέγχου, το 8,2% των παιδιών είχαν παθολογικό Total Frequency Score (TFS) σκορ (συχνότητα δυσλειτουργικών συμπεριφορών) και το 27,5% είχαν παθολογικό Total Problem Score (TPS) σκορ (αριθμός προβλημάτων που ανέφεραν οι γονείς). Τα παιδιά με παθήσεις του πεπτικού συστήματος εμφάνισαν σημαντικά υψηλότερη συχνότητα προβληματικών συμπεριφορών και σημαντικά υψηλότερο αριθμό συμπεριφορών που οι γονείς θεωρούν πρόβλημα. Συγκεκριμένα, το 18,6% της κλινικής ομάδας είχε παθολογικό TFS σκορ και το 39,5% είχε παθολογικό TPS σκορ. Οι δύο ομάδες διέφεραν σημαντικά ως προς τα χαρακτηριστικά σίτισης των παιδιών. Ωστόσο, οι συμπεριφορές που φαίνονται να απασχολούν συχνότερα τους γονείς είναι κοινές και για τις δύο ομάδες και αφορούν την τροφική νεοφοβία, τη μειωμένη κατανάλωση λαχανικών, τη διαπραγμάτευση και τη χρονοτριβή. Ανάμεσα στις δύο ομάδες διαπιστώθηκαν στατιστικά σημαντικές διαφορές σε όλα τα αναπτυξιακά στάδια της σίτισης, σε πολλά χαρακτηριστικά του περιβάλλοντος σίτισης και σε πολλές γονικές πρακτικές. Συγκεκριμένοι δημογραφικοί παράγοντες, ο χαμηλός ΔΜΣ, η καθυστέρηση στη μετάβαση στις στερεές τροφές, αρκετά χαρακτηριστικά του περιβάλλοντος σίτισης και σχεδόν όλες οι γονικές πρακτικές, συσχετίστηκαν θετικά με τις διαταραχές σίτισης στην ομάδα ελέγχου. Λιγότερα χαρακτηριστικά συσχετίστηκαν θετικά με τις διαταραχές σίτισης στην κλινική ομάδα. Συμπεράσματα: Η μελέτη κατέδειξε ότι περίπου ένα στα δέκα υγιή παιδιά εκδηλώνει διαταραχές σίτισης, ενώ ένας στους τέσσερις γονείς θεωρούν προβληματική τη σίτιση του παιδιού τους. Σχεδόν διπλάσιο ποσοστό παιδιών με παθήσεις του πεπτικού συστήματος βρέθηκε να αντιμετωπίζει παρόμοια προβλήματα. Τα ευρήματα της μελέτης συμβάλουν στην πρόληψη, πρώιμη ανίχνευση και αξιολόγηση των διαταραχών σίτισης τόσο στα υγιή παιδιά, όπου τα προβλήματα σίτισης συχνά παραβλέπονται ή υποτιμώνται, όσο και στα παιδιά με παθήσεις του πεπτικού συστήματος που αποτελούν ομάδα υψηλού κινδύνου για την εκδήλωση τέτοιων προβλημάτων. Από τα ευρήματα της μελέτης αναδείχτηκαν επίσης σημαντικές πληροφορίες για τους παράγοντες που επιδρούν στη διατροφική συμπεριφορά, παρέχοντας ένα πλαίσιο αναφοράς για πρώιμη παρέμβαση και για το σχεδιασμό όσο το δυνατό πιο στοχευμένων και αποτελεσματικών θεραπευτικών μεθόδων σε παιδιά με διαταραχές σίτισης.

Acupoints for Tension-Type Headache: A Literature Study Based on Data Mining Technology

Objectives. This study aimed to explore the characteristics and principles of acupoints, which were applied for treating tension-type headache (TTH). Methods. Four databases were searched for the literature studies of treating TTH with acupuncture and moxibustion up to September 1, 2020. Titles, journals, authors, key words, interventions, main acupoints, and outcomes of the included literature studies were extracted and inputted into the self-established Data Excavation Platform of Acupoint Specificity for analysis. Results. In total, 128 papers containing 137 prescriptions, 89 meridian acupoints, and 7 extraordinary acupoints of treating TTH with acupuncture and moxibustion were included. The total frequency of acupoints’ application was 763 times. Fengchi (GB20), Baihui (GV20), Taiyang (EX-HN5), Hegu (LI4), and Taichong (LR3) were used most frequently. The acupoints in Yang meridians were utilized more than those in Yin meridians (66.1% vs. 17.8%), and the acupoints in the Gallbladder Meridian of Foot Shaoyang were applied most commonly. 59.9% (457/763) of the applied acupoints were on the head, face, and neck, and 31.7% (242/763) were on the four limbs. Additionally, the proportion of specific acupoints’ application was 78.2% (597/763). Conclusions. The prescription of Fengchi (GB20), Baihui (GV20), Taiyang (EX-HN5), Hegu (LI4), and Taichong (LR3) might be relatively reasonable in clinical practices of treating TTH with acupuncture, which should be verified in further studies.

Most Frequently Used Vocabulary in Selected English Drama Movie Scripts

Understanding words in motion pictures is a rewarding pathway for audience of cultural-based media and entertainment. The study aimed to investigate the most frequently used vocabulary in selected English drama movie scripts. It sought to find out the most frequently occurred part of speech and to probe the frequency of occurrences of each content words in the movie scripts. Five English drama movie scripts were chosen purposively as sources of the corpora. Applying the Antconc program software developed by Anthony, a total of 108 content words were noted and categorized for corpora analysis. There were 38 verbs, 28 adverbs, 24 nouns and 18 adjectives noted as commonly used vocabulary from the movie scripts. Among the verb types, have (366), can (276) and know (232) emerged as the most frequently occurred action words with a total frequency of 3,142 occurrences. In the case of adverbs, here (237), out (178), and about (163) came out as the most frequently used words with a total occurrence of 1,598. Nouns, on the other hand, have 1,574 occurrences with time (134), tree (133), and going (127) as the most frequently used name words. Adjective was found to be the least frequently occurred content word with 752 occurrences to include right (146), old (54), and only (53) as the top three frequently used noun modifiers. In conclusion, verb outnumbered the other three content words due to drama’s nature of involving the characters into action; and ‘have’ came out as the most frequently used verb because drama scenes imply possessions and obligations.
