An Empirical Study on the Improvement of Attention by Exercise Game Intervention in Children with ADHD

This study aims to verify the attention improvement of ADHD children after sports game intervention, and provide a green and safe intervention path to help ADHD children improve their attention. 16 children with ADHD (experimental group: 10, control group: 5) were selected to carry out exercise game intervention for 24 weeks, 4 times a week, each intervention lasted about 60 minutes. D2 attention test was carried out twice in the experimental group and the control group respectively to observe the attention of children, and the results of attention change in ADHD children before and after the intervention were analyzed. Data were analyzed in SPSS23.0 by independent sample t-test and paired sample t-test. Before the experiment, there was no significant difference between the experimental group and the control group in the scores of each dimension of attention test. After the experiment, the experimental group had significant differences in TN and CP dimensions, but did not have significant differences in other dimensions. Intervention of rich and interesting sports games can effectively improve the selective attention and concentration ability of ADHD children. Therefore, in order to develop the attention of children with ADHD, sports game environment can be created to carry out challenges of team cooperation

Experimental Study on the Influence of “Active Campus” Plan on Physical Fitness and Sports Interest

The exploration of “Activity Campus” action plan for elementary and middle schools in China has been gradually prevailed, but the impact of this plan on students has not been clarified. Based on this, this study is to explores the impact of the Activity Campus action plan on students\u27 physical fitness and sport learning interest through research in “Activity Campus” plan, and provides theoretical support for implementation of the “Activity Campus” plan. 164 fourth-grade students from Shandong Province participate in this experiment, 80 in the experimental group and 84 in the control group. The Primary School Students’ Sports Learning Interest Scale was used to investigate the changes in students\u27 mental health and the Physical Health Test Standard was used to measure students\u27 physical and health levels. The scale and measurement tools have high reliability. At the same time, using independent sample T test analyze the data before and after experiment by spss21.0. For physical fitness level, no significant difference between experimental group and control group in the BMI, 50-meter run, one-minute skipping rope, one-minute sit-ups, and total physical fitness scores before the experiment. After the experiment, the control group had significant differences in vital capacity, 50-meter running, one-minute sit-ups, and total physical fitness for sports learning interest, also no significant difference between experimental group and control group before experiment among the degree of sports participation, positive interest in sports learning, negative interest in sports learning, degree of autonomous learning, and total score in sports learning interest. After experiment, there were significant differences between experimental group and control group in all of above. The research results show that “Activity Campus” plan can effectively improve students\u27 physical fitness and health in terms of speed, strength, endurance, and flexibility, and can effectively improve students\u27 interest in participating in sports and their ability to learn independently. This shows that implementation of the “Activity Campus” action plan in China has certain practical significance

An Exploratory Study of Strengthening Non-Dominant Side of Exercises on ADHD Children in Primary Schools

Empirical studies indicate that children with attention deficit hyperactivity disorder (ADHD) benefited significantly from exercise interventions. Further investigation shows that strength training of non-dominant limbs improves children\u27s athletic ability and cognitive development. This study tested the effectiveness of a strength training intervention on non-dominant limbs for primary school children with ADHD, evaluating its impacts on children’s motor skills. In this experiment, 15 children with ADHD aged 6-10 years were recruited, including 12 boys and 3 girls. All meet the diagnostic criteria of the American Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) for ADHD. Randomly divided into age-matched experimental and control groups, children in the experimental group received intensive training intervention on non-dominant side limbs, and the control group had ADHD Children are not involved in the intervention. Before the experiment, the children and their parents were interviewed on the basic situation of ADHD children. Before and after the experiment, these children of both groups were tested on the TGMD basic motor skills development test and the SNAP-IV scale test, and the parents and children signed the informed consent. The results showed that (1) After the experiment, the experimental group had significantly better overall level of manipulative motor skills and fundamental movement skills than the control group; (2) For the results of SNAP-IV scale, the experimental group (the non-dominant side limb intensive training group) made significantly better progress than the control group (Again, you need to insert t statistics, degree of freedom along with p value here). At the same time, the attention deficit factor of the experimental group and the control group was significantly different before and after the experiment (p \u3c 0.05). More details are needed on the pre- and post-change for both conditions. The results suggest that intensified training on non-dominant limbs can not only improve the motor skills of ADHD children, especially the control ability, but also improve the attention level compared with conventional exercise intervention. It is recommended that strengthening training of non-dominant limbs can be used as more effective exercise intervention for children with ADHD

A57: A Study on the Correlation Between Basic Motor Skills and Attention, Parent-Child Relationship and Behavior

Purpose: In the Curriculum Standards of Physical Education and Health for Compulsory Education (2022 Edition) newly issued by China in 2022, basic motor skills are included in the curriculum, requiring students to learn, practice and experience mobility skills, control skills, manipulative skills, and other basic motor skills. The purpose of this study is to explore the correlation between basic motor skills and pupils\u27 attention, parent-child relationship, and behavior, and to provide a theoretical basis for its further implementation. Methods: In this study, 45 primary school students from Malu Primary School, Jiading District, Shanghai, with an average age of 9.76 years old were randomly selected, including 36 male students and 9 female students. Their parents all signed informed consent. All 45 participants participated in the test of gross motor development-3rd edition (TGMD-3), and 30 parents completed the Achenbach’s Child Behavior Checklist (CBCL), 34 subjects filled in the Family Parent-Child Relationship Scale (PCRT), and 31 subjects conducted the d2 Test of Attention. SPSS was used to analyze the correlation between the test scores of basic motor skills and the attention, parent-child relationship, and behavior. Results: Pearson correlation analysis showed that elementary school students\u27 basic motor skills and attention were moderately correlated (r mobility skills and error of omission =-0.406, P \u3c 0.05, r mobility skills and total error =-0.358, P \u3c 0.05, r control skills and error of omission =-0.428, r control skill and total error =-0.490, P \u3c 0.01, r control skill and correct mark =0.403, P \u3c 0.05, r motor skill total score and error omission =-0.454, P \u3c 0.01, r motor skill total score and total error =-0.468, P \u3c 0.01, r motor skill total score and correct mark =0.379; The basic motor skills of primary school students were moderately correlated with ambivalence parent-child relationship (r control skills and marker correct =-0.390, P \u3c 0.05, r motor skill total and marker correct =-0.391, P \u3c 0.05). There was a high correlation between the manipulative skills and the hyperactive behaviors of the girls in primary school (r=0.917, P \u3c 0.05). Conclusion: The results show that primary school students\u27 basic motor skills and attention, parent-child relationship and behavior have a certain correlation, among which the correlation of control skills is more prominent

3-D motion recovery via low rank matrix analysis

Skeleton tracking is a useful and popular application of Kinect. However, it cannot provide accurate reconstructions for complex motions, especially in the presence of occlusion. This paper proposes a new 3-D motion recovery method based on lowrank matrix analysis to correct invalid or corrupted motions. We address this problem by representing a motion sequence as a matrix, and introducing a convex low-rank matrix recovery model, which fixes erroneous entries and finds the correct low-rank matrix by minimizing nuclear norm and `1-norm of constituent clean motion and error matrices. Experimental results show that our method recovers the corrupted skeleton joints, achieving accurate and smooth reconstructions even for complicated motions

3-D motion recovery via low rank matrix restoration on articulation graphs

This paper addresses the challenge of 3-D skeleton recovery by exploiting the spatio-temporal correlations of corrupted 3D skeleton sequences. A skeleton sequence is represented as a matrix. We propose a novel low-rank solution that effectively integrates both a low-rank model for robust skeleton recovery based on temporal coherence, and an articulation-graph-based isometric constraint for spatial coherence, namely consistency of bone lengths. The proposed model is formulated as a constrained optimization problem, which is efficiently solved by the Augmented Lagrangian Method with a Gauss-Newton solver for the subproblem of isometric optimization. Experimental results on the CMU motion capture dataset and a Kinect dataset show that the proposed approach achieves better recovery accuracy over a state-of-the-art method. The proposed method has wide applicability for skeleton tracking devices, such as the Kinect, because these devices cannot provide accurate reconstructions of complex motions, especially in the presence of occlusion

Long-Lasting Phosphorescence in BaSi\u3csub\u3e2\u3c/sub\u3eO\u3csub\u3e2\u3c/sub\u3eN\u3csub\u3e2\u3c/sub\u3e:Eu\u3csup\u3e2+\u3c/sup\u3e and Ba\u3csub\u3e2\u3c/sub\u3eSiO\u3csub\u3e4\u3c/sub\u3e:Eu\u3csup\u3e2+\u3c/sup\u3e Phases for X-Ray and Cathode Ray Tubes

We report the long-lasting bluish-green phosphorescence for X-ray or cathode ray tubes in the phosphors with compositions of either Ba2SiO4:0.01Eu2+–xSi3N4 (x=0–1) or 2BaCO3–ySi3N4:0.01Eu2+(y=1/6–1) synthesized by a solid-state reaction. By tuning the Si3N4content, the phosphorescence may originate from Eu2+ in BaSi2O2N2(peaking at 490 nm), Ba2SiO4 (505 nm), and Ba3SiO5 (590 nm) phases. The strong phosphorescence of the Ba2SiO4:Eu2+ phase in 2BaCO3–ySi3N4:0.01Eu2+ is attributed to N substitution for O to generate a shallow trap. In Ba2SiO4:0.01Eu2+–xSi3N4 , however, N prefers reacting with Ba2SiO4 to form BaSi2O2N2 , thereby exhibiting a strong phosphorescence of the BaSi2O2N2:Eu2+ phase but a weak phosphorescence of the Ba2SiO4:Eu2+ phase

Effect of Exercise Intervention on Social Ability of ADHD Children

The incidence rate of attention deficit hyperactivity disorder (ADHD) is 7.25% in China. The main symptoms are attention deficit laxation, behavior impulsivity, social disorder and so on. Children aged 3-6 are in the golden age of social ability development. Therefore, if ADHD children at this age do not get correct and effective interventions, it will have a far-reaching impact on their social ability. In order to explore new intervention measures for ADHD children and improve their social ability, this study will intervene ADHD children through sports intervention, so as to provide theoretical and experimental basis for improving their social ability. A total of 12 hyperactivity prone children aged 3-6 years were recruited in this study. The subjects were intervened through engaging in KDL sports game, parent-child homework and parent-child carnival for four months. We used Achenbach children\u27s behavior scale (CBCL) to evaluate children\u27s social ability from activity ability, social ability and learning. In order to reduce the experimental error, before using the CBCL scale, the researchers have been trained in learning and understanding the specific rules and scoring methods of the CBCL scale to ensure that evaluated data have good reliability and validity. After data collection, SPSS 23.0 was used to conduct statistical analysis on the data. The results showed that after the intervention, the ADHD children significantly improved their social ability from the baseline to the post-test (Tsocial = -1.39, psocial = 0.01 \u3c 0.05). However, the results showed that there was no significant difference in children\u27s activity ability and learning over time (Tactivity = 0.42, pactivity = 0.533 \u3e 0.05; Tlearning = -0.12, plearning = 0.756 \u3e 0.05). Exercise intervention can effectively improve the social ability of ADHD children, which is more harmonious with their peers and more able to communicate with their families. We suggest to carry out exercise intervention for more children with ADHD and to integrate behavioral therapy with multi-directional intervention

Effects of Billet-Making Methods on Volatile Flavor Components of Sanhua Plum Fruit Billets Based on Headspace-Gas Chromatography-Ion Mobility Spectroscopy and Electronic Nose

In order to investigate the effect of billet-making methods on the volatile components of the Sanhua plum fruit billets, electronic nose and headspace-gas chromatography-ion mobility spectroscopy (HS-GC-IMS) were used to analyze and compare the volatile components of four groups of samples of salt cured, sulfite mixed salt cured, lactic acid bacteria fermented fruit billets and fresh fruit control. The results showed that both the electronic nose linear discriminant analysis (LDA) and the principal component analysis based on the HS-GC-IMS assay results clearly distinguished the four groups of samples, the flavor characteristics of fresh fruits were significantly changed after different curing treatments, and the differences among fruit blanks samples were significant. HS-GC-IMS detected and identified a total of 49 volatile compounds in four groups of samples, and the high relative contents were mainly alcohols, esters and aldehydes. The relative odor activity value (ROAV) showed significant differences in key flavor substances among the three fruit billets, the lactic acid fermented fruit billet had the highest total peak volume of volatile flavor substances (194760) and the most types of key flavor substances (10), mainly short-chain aldehydes. From the perspective of flavor richness of fruit billets, the flavor quality of fruit billet by lactic acid fermentation was considered to be better. The results of this study provided an useful reference for the selection of the billet-making methods of Sanhua plums

Spatio-temporal reconstruction for 3D motion recovery

—This paper addresses the challenge of 3D motion recovery by exploiting the spatio-temporal correlations of corrupted 3D skeleton sequences. We propose a new 3D motion recovery method using spatio-temporal reconstruction, which uses joint low-rank and sparse priors to exploit temporal correlation and an isometric constraint for spatial correlation. The proposed model is formulated as a constrained optimization problem, which is efficiently solved by the augmented Lagrangian method with a Gauss-Newton solver for the subproblem of isometric optimization. Experimental results on the CMU motion capture dataset, Edinburgh dataset and two Kinect datasets demonstrate that the proposed approach achieves better motion recovery than state-of-the-art methods. The proposed method is applicable to Kinect-like skeleton tracking devices and pose estimation methods that cannot provide accurate estimation of complex motions, especially in the presence of occlusion
