Authors: Liu Yujiao 
Published: February 2025

Abstract
The digital information era is experiencing a daily increase in data, making the optimization of forms for data recording and processing an urgent problem. This paper addresses this need by designing intelligent dynamic forms using B/S architecture and adding drag-and-drop designs to optimize the form layout. Dynamic forms are created using virtual tables and displayed on the browser. The reported data in the server is used to calculate the variance to find out the method to make the increase in the data volume of each data table close to the average value and complete the optimized storage of the reported data. Drag-and-drop layout of the form is achieved by clicking and dragging the form components to the form design area using the APIs such as mousedown, mousemove, and mouseup. Dynamic form layout evaluation metrics are established through subjects’ eye movement data and questionnaire results. The drag-and-drop layout designed in this paper can significantly reduce the total gaze time, the number of gaze points, and the number of eye jumps of the subjects, in which the total gaze time is reduced by 29.06% and 26.70% compared with the waterfall and distributed layouts. The operation satisfaction score for the drag-and-drop layout is 80.26, which is a significant improvement from the other two layout methods. The drag-and-drop layout in this paper effectively reduces the cognitive load of users, which is obviously helpful for them to process the relevant data.

Authors: He Xifang 
Published: February 2025

Abstract
In recent years, the development of tourism has been in full swing, attracting a large number of investment institutions. This paper manages the risk of tourism investment using the VaR model based on big data. Taking Literature and Tourism Fund A as the research object, the VaR model is used to measure the risk of its investment portfolio, analyse the risk of Literature and Tourism Fund A’s investment portfolio, and make corresponding adjustments accordingly to construct a simulation fund. Then, the simulated fund is compared with the pre-adjusted Venture Capital Fund A in terms of return and risk to judge whether the portfolio adjusted according to the VaR measure has better results. Of the eight stocks in the Venturing Fund A, Stock 1, Stock 3, and Stock 6 have the highest risk contributions of 22.58%, 15.26%, and 13.78% respectively, for a combined risk contribution of 51.62%. Stock 1 was the main source of risk. The fund’s return rally is anchored by Equity 2 and Equity 5, whose investment weightings are significantly higher than their risk contributions. With a long-term return of 25.64 per cent and an average VaR of 1.049 per cent, the simulated fund portfolio had a higher return than the pre-adjusted Venture Capital Fund A and the benchmark index while being much less risky than the Venture Capital Fund A and the benchmark index.

Authors: Jia Manli 
Published: February 2025

Abstract
This paper provides strong support for the construction of online and offline blended English teaching modes. Firstly, it applies the parallel K-means clustering algorithm of the adaptive cuckoo search to cluster and analyze the data related to blended English teaching. This process results in a series of processed teaching data, which is then used to design a blended English teaching evaluation index system for college students. The teaching data obtained is used to design the system. Aiming at the shortcoming that there is no theoretical basis for the selection of many parameters in the training process of the BP neural network, a teaching quality evaluation model based on the GA-BP neural network is constructed. Then, the blended teaching model is constructed based on this evaluation model. Through empirical experiments, it was found that the overall mean English achievement of the experimental group increased by 19.2% after the implementation of the hybrid teaching model, which was 6.7% higher than that of the benchmark group. The results demonstrate that the blended teaching model, which is based on the GA-BP blended teaching quality evaluation model, enhances college students’ English performance and is suitable for widespread application in college English teaching.

Authors: Jiang Nenghui , Li Cheng 
Published: February 2025

Abstract
Self-driving intelligent vehicles are an important part of the future intelligent transport system, and the study of path planning and automatic obstacle avoidance is also a key technology for the realization of self-driving vehicles. In this paper, we first constructed a dynamics model of an intelligent car, and then, using the optimal control theory, we designed the performance index function of automated obstacle avoidance path planning. This function took into account factors such as driving efficiency, energy consumption, and ride comfort. Consequently, we constructed an optimization algorithm model for automated obstacle avoidance path planning for intelligent cars and experimentally verified its effectiveness. The obstacle avoidance experiments conducted on straight and curved roads demonstrate that the path planning performance index function, which is based on optimal control theory and the optimal path planning method in this paper, can meet the obstacle avoidance requirements of local path planning while ensuring ride comfort. In the static obstacle experiment, the vehicle speed is 63 km/h and 84 km/h in two cases. This paper proposes a path planning function for obstacle avoidance that uses a smaller swing angle and maximum distance away from the obstacle than the traditional approach. The performance of the obstacle avoidance function based on optimal control theory in this paper is 47% higher than that of the traditional obstacle avoidance function. This verifies the effectiveness of optimal control theory in automatic obstacle avoidance path planning optimization for intelligent vehicles.

Published: February 2025

Abstract
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

Abstract
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.

Abstract
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.

Authors: Simatupang Mikhael Stefanus Filemon , Siregar Jessica , Prayogi Galih 
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.
Abstrak
Penelitian ini membandingkan perhitungan biaya pekerjaan pile cap menggunakan metode konvensional dan BIM pada proyek gedung laboratorium BTKP Jakarta Utara. Pemilihan objek studi didasarkan pada kompleksitas dan keunikan tipe pile cap yang terdapat pada proyek tersebut. Analisis perbandingan ini bertujuan mengevaluasi efektivitas kedua metode dalam estimasi biaya konstruksi, mengingat pile cap merupakan elemen fondasi yang membutuhkan perencanaan teknis dan finansial yang akurat. Meskipun metode konvensional umum digunakan, tetapi sering kali menghadapi tantangan dalam hal efisiensi waktu dan akurasi data. Di sisi lain, metode BIM menawarkan potensi untuk meningkatkan efisiensi perhitungan volume penulangan melalui model 3D yang memperhitungkan pengurangan panjang pada tiap tipe besi, berbeda dengan perhitungan manual yang cenderung menunjukkan perhitungan tipe besi yang lebih panjang. Hasil penelitian menunjukkan bahwa biaya pekerjaan pile cap tipe PC4 dengan metode BIM lebih murah (Rp 70.356.230,32) dibandingkan dengan metode konvensional (Rp 71.038.864,28), menandakan potensi efisiensi waktu dan biaya dengan penerapan Building Information Modeling (BIM). Penelitian ini memberikan dasar kuat bagi keputusan penggunaan BIM dalam proyek konstruksi di Indonesia, mempertimbangkan efisiensi dan akurasi sebagai faktor kunci dalam pengembangan industri konstruksi ke depan.

Published: February 2025

Abstract
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.

Published: February 2025

Objetivos: Descrever o perfil epidemiológico dos pacientes submetidos à cirurgia ambulatorial de pequeno porte e analisar a relação entre a classificação ASA e complicações pós-operatórias Métodos: Estudo observacional e quantitativo realizado com pacientes atendidos em ambulatório acadêmico, entre fevereiro de 2023 e fevereiro de 2024. Estatísticas descritivas, incluindo valores médios e medianos, foram empregadas para análise dos dados. Para avaliar a associação da classificação ASA e complicações pós-operatórias foi aplicado o Teste Exato de Fisher. Resultados: O estudo avaliou 70 pacientes submetidos à cirurgia ambulatorial, em unidade ambulatorial acadêmica tipo I. Homens e mulheres apresentaram distribuição próxima e mais de setenta por cento dos participantes registraram pelo menos uma comorbidade. A maioria dos pacientes (45,71%) estava na faixa etária de 60 anos e mais. Encontrou-se maior prevalência de lesões não neoplásicas e, dentre as neoplásicas, a maioria recebeu o diagnóstico de carcinoma basocelular. A classificação ASA não apresentou uma correlação significativa com complicações pós-operatórias (IC 95%; p = 0,5509). Conclusão: Cirurgias ambulatoriais de pequeno porte, em unidade ambulatorial tipo I, podem ser realizadas com bons resultados e pequenos índices de complicação pós-operatória, em pacientes idosos e com comorbidades controladas. Todavia o pequeno tamanho da amostra requer estudos com populações maiores.
