Authors: Li Menghan , Zhang Li
Published: February 2025

In the era of big data, the rich content of music curricula has brought about the problem of “curriculum content overload.” It is crucial to improve the quality of music education by effectively guiding learners to find the content they are interested in among the vast array of course resources. In this paper, we use big data analytics to investigate the correlation between students’ learning behaviors and courses and to design a personalized course recommendation system for students. Based on the Hadoop big data distributed computing framework, we incorporate the Node2vec algorithm, combine it with machine learning to train learning behavior data, and propose a course content recommendation method based on Node2vec. Analysis of the data shows that the performance of the Node2vec algorithm on Pre@20, Recall@20, NDCG@20, MRR, and AUC evaluation metrics improves by 10.23%, 5.96%, 14.89%, 9.05%, and 4.14% compared to the best performance of the eight baseline models on each evaluation metric. It validates the effectiveness of this paper’s method in recommending course content, as well as its practicality. It also proposes an effective implementation path for enhancing the content of music education courses.

Published: February 2025

Under the double challenges of energy crisis and climate warming, electric vehicles have received widespread attention as an important way to develop a low-carbon economy and implement energy saving and emission reduction, among which the electric vehicle power exchange is the main direction of current research. In this paper, we analyze the development needs of electric vehicles and provide an in-depth analysis of the power exchange mode of electric vehicles. The state of the battery is especially critical in the process of power exchange between electric vehicles. In order to realize the real-time monitoring of the battery health state in the process of electric vehicle power exchange, this paper uses RLS to establish a battery model and perform parameter identification. Then, on the basis of the second-order Thevenin equivalent circuit model, the Kalman filter algorithm is used to estimate the battery health state. On this basis, this paper constructs a real-time battery health status monitoring system for electric vehicle power exchange using sensors, transformers, displays, DSPs, and other components. Through simulation experiments, the percentage error of the equivalent circuit is between -0.4% and 0.3% in both cases.

In order to promote the high-quality development of higher education and achieve the development goal of a strong education country, college education should pay attention to the integration and development of the content optimisation of civic and political education and practical training so as to achieve the educational goal of cultivating high-quality talents. In order to enhance the effect of content optimisation of civic and political education in colleges and universities, this paper proposes the process of content optimisation of civic and political education based on the ADDIE model and introduces the structural equation model to analyse the influence of each link on the optimisation of civic and political education content. Based on the optimised content of Civic and Political Education in the ADDIE model, a blended teaching model of Civic and Political Education in colleges and universities was established by combining BOPPPS+ blended teaching, and a teaching comparison experiment was designed to analyse its practical nurturing effect. The development link in the optimisation effect model of the content of Civic and Political Education has the most significant effect on the optimisation of the content of Civic and Political Education, and its path coefficient is 0.651. After carrying out BOPPPS+ blended teaching, the learning attitude and learning motivation of the students in the experimental class increased by 26.67% and 36.36%, respectively, and the mean score of the students’ feelings about the practical nurturing teaching effect of the Civic and Political Education course reached 6.18 points. The use of the ADDIE model to achieve the optimisation of the content of Civic and Political Education, combined with blended teaching, can enhance the effect of the practical nurturing experience of Civic and Political Education in colleges and universities and better cultivate the students’ Civic and Political literacy.

Published: February 2025

This study aims to analyze the role of perfectionism on social anxiety in college students who use social media in the Jakarta area. Social media has become an integral part of college students' lives, but it often triggers social pressure and negative comparisons related to perfectionism. Perfectionism itself is a broad concept, and one aspect of it that has the potential to increase social anxiety is Perfectionistic Self-Presentation. This concept describes a maladaptive behavior in which individuals strive to constantly display perfection while hiding imperfections which in turn increases fears of negative social evaluation and exacerbates social anxiety in social media users. This study used a non-experimental quantitative approach with purposive sampling method. A total of 230 college students aged 18-25 years old who actively use social media for at least two hours per day became participants. Data were collected using the Hewitt and Flett Multidimensional Perfectionism Scale (HF-MPS) and the Social Anxiety Scale for Social Media Users (SAS-SMU) which have been adapted into Indonesian. The main data analysis in the form of regression tests showed a significant positive influence between perfectionism and social anxiety, with a contribution of 89.9%, while the remaining 10.1% was influenced by other factors that were not studied.

Russian Literature at the Lessons of English Grammar
Authors:   MGIMO University, Tretjukhin A.
Published: February 2025

The article focuses on the proposition that certain rules of English grammar in a class of Russian-speaking students may be illustrated not only by the examples culled from English primary sources, which is indispensable, but, ironically, also by the examples drawn from Russian classical literature. This source of teach­ing examples has been completely overlooked in the contempo­rary textbooks put together by non-native Russian-speaking instructors of English. The article is looking to show that the usefulness of such examples goes far beyond the fact that the majority of them sound familiar to any Russian. Given that all Russian classical texts have been translated into English many times over by different translators, the most valuable thing about these examples is that they allow a comparative grammar analysis of different translations of the same Russian literary episode. The article describes a few observations thus made concerning English conditional sentences. In practical terms, the task of building a body of the sought-after examples from the original text along with a few translations is possible through the internet.

Published: February 2025

This research compares the cost calculation of pile cap construction using conventional and BIM methods in the BTKP laboratory building project in North Jakarta. The selection of the study object was based on the complexity and uniqueness of the pile cap types found in the project. This comparative analysis aims to evaluate the effectiveness of both methods in construction cost estimation, considering that pile cap is a foundation element that requires accurate technical and financial planning. Although conventional methods are commonly used, the challenges in terms of time efficiency and data accuracy are often experienced. On the other hand, the BIM method offers the potential to improve the efficiency of reinforcement volume calculations through 3D models that account for length reductions in each type of reinforcement, unlike manual calculations that tend to show longer reinforcement type calculations. The results show that the cost of PC4 type pile cap construction using the BIM method is lower (IDR 70,356,230.32) compared to the conventional method (IDR 71,038,864.28), indicating the potential for time and cost efficiency with the implementation of Building Information Modeling (BIM). This study provides a strong foundation for decisions regarding the use of BIM in construction projects in Indonesia, considering efficiency and accuracy as key factors in the future development of the construction industry.

Analisis mencakup parameter seperti jumlah lapisan geogrid, kedalaman penempatan, dan kekakuan tariknya. Hasil menunjukkan bahwa penggunaan geogrid secara signifikan meningkatkan stabilitas lereng, dengan FoS meningkat hingga 35% dalam konfigurasi optimal. Selain itu, penelitian ini menyoroti pengurangan perpindahan horizontal dan vertikal, sehingga memastikan kinerja jangka panjang. Penelitian ini memberikan wawasan praktis untuk perancangan lereng yang diperkuat pada medan yang menantang, khususnya untuk pembangunan infrastruktur. Temuan ini menegaskan pentingnya integrasi geosintetik dalam desain lereng untuk meningkatkan keamanan, mengurangi risiko, dan mengoptimalkan biaya konstruksi. Penelitian selanjutnya dapat mengeksplorasi interaksi antara geogrid dan berbagai jenis tanah di bawah beban dinamis.

Authors: Liu Baochen , Liu Honggang
Published: February 2025

This study explores the emotional intelligence of middle school English as a foreign language (EFL) teachers in Northeast China, aiming to assess its factor structure and factor levels. Using a revised version of the Emotional Intelligence Questionnaire, data were collected from 1,017 participants. The results indicate that the teachers generally exhibited a high level of emotional intelligence, with relatively high scores in all four sub-dimensions: self-awareness, self-regulation, motivation, and interpersonal connection. Additionally, the study employed both quantitative and qualitative methods to validate the factor structure of EI. The findings reveal that teachers with higher EI tend to show greater self-awareness, emotional regulation, and motivation, which contributes to their overall job satisfaction and effective teaching practices. The results also underscore the importance of EI in coping with emotional challenges in the classroom and its potential role in improving educational quality.

The paper presents the development of a single-phase nano retarded acid system and its application in carbonate reservoirs that delivered significant increases in oil and gas production. The key contributing factors include a novel nano-emulsified acid and a low-concentration friction reducer. The combination of low fluid viscosity and strong retardation offers both ease of operation on the surface and deep acid penetration in the reservoir. Matrix acidizing and acid fracturing treatments using such acid systems resulted in an obvious increase in production.

While acidizing is highly effective in bypassing formation damage such as emulsion, water lock, organic scale, and polymer residue in carbonate reservoirs, depth of acid penetration remains a challenge, especially at high temperatures. Nano-emulsion is a single-phase system with low interface tension, good wetting properties, and slow reactions. Since the surfactant is embedded in nano-emulsion it absorbs much less on the rock surface than conventional surfactant providing a longer travel distance in the formation. The nano-emulsion, which combines the advantages of acid retardation, formation wetting, scale dissolving capability, and ease of mixing has been proven to be highly effective in stimulating carbonate reservoirs.

The single-phase retarded acid system is an oil-in-water nanoemulsion system with droplet size distribution of 8 to 100nm. It overcomes the challenges of high friction pressure of emulsified acid and polymer residue damage of gelled acid and has a strong retardation effect. Lab results demonstrated greater than 90% in rate of retardation, more than 75% reduction in friction pressure, and high acid-etched fracture conductivity. The system is capable of simultaneously dissolving organic scale and inorganic scale. It was also shown to remove formation damage caused by emulsion, water lock, and change in wettability. The embedded surfactant is adsorbed on the rock surface through electrostatic interaction from the positive charge carbonate by negative charge surfactant. The barrier resulting from rock and nanoemulsion interaction gave rise to the strong retardation effect. High fracture conductivity was realized by differential acid etching through viscous fingering. Since the nano-emulsion contains organic solvent and aqueous acid it can remove both organic and inorganic scale as a single fluid. The nano retarded acid has been successfully applied in 40 wells in offshore China and the Missan oilfield of Iraq. The stimulation treatments delivered up to 3-fold increase in oil and gas production.

Objetivos: Avaliar o tempo para o diagnóstico das Doenças Inflamatórias Intestinais (DII) em um centro no nordeste do Brasil. Métodos: Estudo observacional, retrospectivo e transversal. Foram coletados dados nos prontuários eletrônicos do hospital, incluindo pacientes acima de 18 anos atendidos de 2013 a 2021 e com diagnóstico confirmado de Doença de Crohn (DC) ou Retocolite Ulcerativa (RCU). Resultados: Foram incluídos 678 pacientes, dos quais 346 tinham RCU e 332 tinham DC. O tempo para o diagnóstico das DII teve média de 24,8 meses e mediana de 9,0 meses (variação de 1 mês a 432 meses). A mediana do atraso no diagnóstico da DC foi maior para os comportamentos B2 (estenosante), com 12 meses, e B3 (penetrante), com 20 meses. A mediana do atraso diagnóstico de RCU teve resultados estatisticamente significantes (p <0,05) para a extensão da doença, com E3 (pancolite: 8,0 meses) < E2 (colite esquerda: 9,0 meses) < E1 (proctite: 9,5 meses). Conclusão: Os resultados deste estudo indicaram que o tempo para o diagnóstico das DII teve grande variação temporal e esses resultados foram influenciados pela extensão da RCU e pelo comportamento da DC. Esse atraso diagnóstico pode impactar negativamente no prognóstico das DII.

Objetivo: Reunir dados laboratoriais de triglicérides (TG) e lipoproteínas de baixa densidade (LDL) e comparar ao risco do desenvolvimento de acidentes vasculares cardíacos (AVC). Métodos: Estudo de natureza observacional, transversal, com abordagem quantitativa analítica, baseado na análise dos níveis de LDL e TG dos pacientes do LAC - PUC Goiás no período de outubro de 2023 a novembro de 2023.  Os dados foram tabulados pelo Microsoft Office Excel 365 e analisados com o Statistical Package for Social Science. Resultados Foram analisados 1025 pacientes, com relação ao sexo e a classificação de hipercolesterolemia isolada, hiperlipidemia mista e hipertrigliceridemia isolada da amostra, o valor de p foi de 0,725, indicando ausência de relação significativa. Em relação às faixas etárias, foi obtido um valor de p<0,001, evidenciando uma relação significativa. A análise post hoc revelou uma prevalência maior de hipertrigliceridemia isolada na faixa etária de 50 a 59 anos (23,8%). Conclusão: É necessária maior atenção aos pacientes que estão entrando na faixa etária de 50 a 59 anos, com o intuito de triar, diagnosticar e oferecer um tratamento que atue na prevenção de possíveis AVC.
