Authors: Lan Feipeng , Peng Xiaoyan 
Published: October 2024

Abstract
The construction of ideological and political education and the construction of academic style are complementary to each other and jointly committed to the good development of education and teaching in colleges and universities. This paper starts from the relationship between the two, discusses the interaction between ideological and political education and the construction of academic style in colleges and universities, and draws out the methodological path of ideological and political education in colleges and universities to lead the construction of academic style. It proposes interactive teaching methods to strengthen the construction of ideological and political education by utilizing the interactive teaching process between teachers and students. It points out that the digital video coding technology (H.265/HEVC intra-frame coding technology and H.265/HEVC rate-distortion optimization technology) and the video encryption mechanism based on H.265/HEVC optimize the processing of interactive video to enhance the interactive performance of ideological and political academic style. By comparing the coding performance of H.264 and H.265, as well as the PNSR and SSIM evaluation indices, the rationality of the proposed digital video coding and encryption technology is verified. A survey on the academic style construction of different majors and grades, as well as an analysis of the attitude of Civics academic style construction, is conducted in the sample schools to find out what can be optimized in the academic style construction of Civics education in colleges and universities. In all five schools, 4.76% of students believe that the academic culture situation is not conducive to the current learning culture. However, 58.96% and 14.46% of the groups think that learning is something that has to be done and something that is not interesting, indicating that there is still a lack of interest in the teaching interaction of Civics and Political Science style, and schools should make full use of digital technology to attract students to carry out teaching interaction.

Abstract
After a long period of development and evolution, Chinese painting has formed a set of regular artistic language, which highlights the national characteristics of Chinese painting and is an important factor distinguishing it from other works of art. As the main characteristic of Chinese painting, this paper analyzes the traditional techniques of Chinese painting according to the three characteristics of Chinese painting: line, ink, and color, and analyzes the language of programed techniques. Then the method of digital reproduction of traditional techniques of Chinese painting is proposed and elaborated with the example of “The Western Garden of Elegant Gathering”. Subsequently, for the complexity of hand movement recognition of Chinese painting techniques, this paper proposes a sample splitting and re-fusion algorithm RCF based on sEMG to optimize the hand movement signals and construct a hand movement recognition model based on surface EMG signals. Through empirical analysis, the SVM classifier used in this paper has an average recognition correctness rate of 98%, which is 6% and 3% higher than BP and LDA, respectively. Meanwhile, the recognition accuracy of the hand movements of the eight techniques is all above 95%, with an average recognition accuracy of 98.5%. The mean value of all five indicators of the experience evaluation of Chinese painting techniques reproduction and innovation exceeded 4 points, and the overall average score was 4.542, indicating that the experiencers were very satisfied with the experience of Chinese painting techniques reproduction to innovation in this paper. The research of this paper provides theoretical and technical guidance for the reproduction and innovation of traditional Chinese painting techniques, as well as ideas for the organic combination of digital technology and traditional Chinese paintings.

Published: October 2024

Abstract
The rise of the Internet has brought about a rapid growth of unstructured data recorded in the form of text and audio. Two key techniques that can be used to process text data are proposed in this study, which applies deep learning techniques to unstructured data processing. First, the transformer feature extractor is used to characterize dynamic word vectors. Then, the MCNN neural network is combined with it to perform key information screening and construct a text classification model based on the MCNN transformer. Then, the text features extracted from the BERT model are input into the VAEGRU module, combined with the self-attention mechanism and the K-Means algorithm, to construct the text clustering model based on VAE-GRU. The MCNN-transformer model achieves a high level of accuracy and Macro-F1 value that exceeds 0.880 and is superior to other text categorization models through experimental analysis. The ACC and NMI results of the VAE-GRU model are both greater than 70% on the Stack Overflow and SearchSnippets datasets and greater than 48% on the Chinese dataset are greater than 48%, and their performance is better than the three ablation models by 15.03% to 85.67%. In this paper, the MCNN-transformer model and the VAE-GRU model are capable of competent classification and clustering processing in unstructured text data, which help to improve the efficiency of information understanding and utilization of unstructured data.

Authors: Wu Yan 
Published: October 2024

Abstract
Augmented reality technology is a cutting-edge technology of current social development, and its development promotes the development and change of people’s social production and lifestyle. In this paper, combining the key aspects of sports teaching, training, and actual combat confrontation, the construction of a VR-based immersive sports teaching environment is realized from the aspects of sports teaching materials and sports action and tactical training. Subsequently, using the bit position registration algorithm that integrates complementary filtering (CF) and untraceable Kalman filtering (UKF), as well as the TDOA localization algorithm, a VR sports-assisted training system was designed, and the performance and application effects of the system were empirically analyzed. The login page time of the system is within 3.30s, and the corresponding CPU utilization rate is 43%~50%, which is in line with the expected effect, indicating that it has good usability performance. Fusion filtering on posture angle has a lower error value than CF and UKF, which suggests higher accuracy and is suitable for posture registration in VR sports-assisted training. The TDOA localization algorithm has an error range of [0.127m, 0.389m] and a 50% error below 0.292m, which can be utilized for motion tracking in VR sports-assisted training. The experimental group using the VR sports teaching environment is significantly better than the control group using traditional teaching methods in both visual-sensory perception and technical assessment, which indicates that the VR immersive sports teaching environment constructed in this paper has practical feasibility, and provides a model reference and experience for realizing the practical application of AR technology in sports.

Published: October 2024

Abstract
Spoken English teaching is a teaching scenario characterized by multimodality, which requires teachers’ verbal and nonverbal to cooperate. In the context of the high degree of integration of artificial intelligence and educational technology, the construction of an English speaking multimodal assessment method is of great significance for English speaking training and teaching. This paper constructs a multimodal teaching model of spoken English based on three modalities: audio, text, and video. Taking the English speech of Chinese college students as the research object, we improve the traditional computerized English pronunciation quality evaluation method, consider the multi-parametric evaluation indexes such as pitch, speech rate, rhythm and intonation, and convert the recognition problem into a scoring problem by utilizing the soft classification property of the ANN model. The confidence probability output value of the ANN model is used as the metric for evaluation results. Through experiments, it is proved that the accurate agreement rate of the spoken English assessment method in this paper is 89.87% and R
2 is 0.528 under the gold standard, and the data results prove that the assessment method is credible. It can give learners of spoken English timely, accurate and objective evaluation and feedback guidance and help learners find out the differences between their pronunciation and the standard pronunciation so as to improve the efficiency of spoken English learning.

This research builds upon the author's earlier work on the design of a cassava pulling tool. The aim is to develop a non-mechanical or minimally-powered tool that addresses farmer needs. The tool design incorporates Quality Function Deployment (QFD) to ensure user satisfaction. QFD is a method that integrates customer desires into technical requirements during the design phase, prior to production. Data analysis revealed key user desires: lightweight materials, affordability, the ability to pull multiple cassava stems simultaneously, durability, safety, and additional functionalities. House of Quality (HOQ) analysis identified the most crucial attribute (weight of importance: 30%) as the ability to pull multiple stems at once. This finding served as the primary basis for prototype development and technical characteristic definition. Subsequent prototype testing successfully uprooted cassava plants, demonstrating the tool's capability of pulling multiple stems in a single operation.

Authors: Al Rubaye Amal Mahdi , Sharquie Inas K. , Gorial Faiq I. 
Published: October 2024

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that has a genetic predisposition and a complex pathogenesis in which the involvement of various cytokines has been shown. In the current study, serum interleukin-39 (IL-39) levels from 99 patients with SLE and 33 healthy control subjects who attended the Baghdad Teaching Hospital Rheumatology Unit were examined. Patients were divided into 3 subgroups according to disease status: inactive (n = 33), active moderate (n = 33), and active severe (n = 33). This topic has not yet been explored, so the significance of IL-39 as a biomarker for SLE was evaluated. Cytokine levels were measured using enzyme-linked immunosorbent assay kits. Full medical histories, body mass index, gender, and clinical disease activity, the latter evaluated using the SLE disease activity index, were documented. Laboratory disease parameters, including anti-dsDNA antibodies, C3 and C4 levels, erythrocyte sedimentation rate, and C-reactive protein titres, were measured. The mean age of patients was 33.92 ± 0.91 years. The IL-39 level was higher in patients (13.70 ± 0.35 ng/l) than in controls (10.67 ± 0.19 ng/l, p < 0.01). The mean of IL-39 levels was highest in patients with active severe SLE (17.42 ± 0.48 ng/l) and then became incrementally lower with reducing disease severity, i.e., active moderate, 13.34 ± 0.23 ng/l; inactive, 10.93 ± 0.24 ng/l. Serum IL-39 showed good validity for the diagnosis of SLE. With a cut-off value ≥ 10.25 ng/l and an area under the curve of 0.79, diagnostic sensitivity, accuracy, and specificity were 79.98%, 51.5%, and 71.97%, respectively. In conclusion, serum IL-39 levels were significantly higher in patients with SLE than in healthy controls and were correlated with disease activity. This interleukin may be useful in predicting disease severity.
Multiple Upward Residual Gravity and Magnetic Maps to Estimate the Deep Crustal Layers and Moho Discontinuity in Eastern Iraq
Authors: Al-Banna Ahmed Sh. , Majeed Hayder H. 
Published: October 2024

The upward continuation technique was applied to the gravity and magnetic data to obtain the residual anomalies maps in eastern Iraq. A new processing method is introduced to calculate the crustal layers depending on the relation between the total range of the residual anomalies of gravity, magnetic data and the upward continuation, with multi-elevations. The significant relationship shows slope variations, which may reflect the maximum contrast in the physical properties (density and/or susceptibility) and the intersection point representing the depth of layer contacts. This method was applied to the eastern central part of Iraq, adjacent to the Iranian borders. It is found that the average depth range to the Jurassic formations, top basement rocks, transition layer (Curie point), and Moho discontinuity are 3.1- 4.8 km, 8-12.9 km, 20.9-22.4 km and 43.6 km, respectively. The Sedimentary cover in the study area ranges from 8 to 13 km. The maximum depth to the Moho discontinuity obtained by gravity data in the study area is 43.6 km. The radially average power spectrum technique was applied in the study area to calculate the gravity depth and magnetic sources' depth. Three depth levels of sources from gravity and magnetic data were obtained. These depths are shallow sources, average basement rock and deep sources (Moho) at 3km, 13.2-12.1 km, and 32.2-34km, respectively. The obtained results concerning the main layers in the crust were compared between the two methods, and the new method shows more reliable results. The detected depth levels refer to top Jurassic, basement rocks, and Moho discontinuity. The new method is believed to be used to detect the crustal layers depth with good results.
Determining the Relationship between the Crescent Visibility Factors and the Coordinates of the Sun and Moon
Authors: Taher Mohammed Y. , Abdulla Fouad M. 
Published: October 2024

The study of the relationship between the coordinates of the sun and the moon with the crescent visibility factors has not been previously treated in a detailed and accurate way in research and previous studies, despite its religious importance. Accordingly, this paper aims to study the relationship between the crescent visibility factors (age, lag time, elongation (ARCL), arc of vision or relative altitude (ARCV), relative azimuth (DAZ), and crescent width (W), with coordinates of the sun and the moon), and how it varies during the day of the crescent's observation. In this paper, Matlab programs were designed to calculate the ecliptic sun and moon coordinates (λ, β) and in the presence of all perturbation impacts (planets), then convert these coordinates to the equatorial (α, δ) and horizontal coordinates (A, a). The results were compared with other programs in this field and references such as the ephemeris, accurate times, and astronomical programs. The variation of the sun and moon coordinates (ecliptic, equatorial, and horizontal) was studied with time, and the relationship of those coordinates was explained with visibility crescent factors during the day of the crescent's observation. Finally, the relationship of those factors with each other was studied. The results indicated that there was a relationship between the sun and the moon coordinates with some factors of crescent visibility in critical and standard observations, where the critical observations of the moon (age, lag time, elongation) were increased when the sun and the moon coordinates approach from two equinox points (spring and autumn), while the other factors, such as the relative azimuth and relative altitude, were independent on the change of the coordinates through the year. Also, a relationship was found between the visibility factors with each other, this led to a direct relationship between increasing the elongation with the crescent width. The values of the relative altitude were also increased with the increase in the lag time. Lastly, there was a direct relationship between the increase in the relative azimuth and the relative altitude.
