It is particularly important to identify and prevent telecom scams that trick victims into transferring funds through phone calls, Internet and text messages. Based on the collected data, a prediction model of telecom bank card fraud is established in this paper. In the analysis, we first checked the data missing through Pandas and missingno library, and conducted Pearson correlation analysis, and found that the ratio of transaction amount has a strong positive correlation with fraud. In terms of data preprocessing, outliers are defined and data are cleaned by box diagram, missing values are processed by KNN filling, and data is normalized by Yeo-Johnson transformation. Then, the importance of features is calculated by random forest and GBDT, and the features with greater influence are selected. In the model training, XGBoost, LightGBM and CatBoost integrated learning algorithms were selected, and the optimal model configuration was obtained through parameter optimization, and finally integrated into BaggingClassifier. The model performance evaluation shows that the prediction accuracy of the model established in this paper is up to 99.99%.

This article aims to explore the specific paths and methods of integrating ideological elements into the construction of management courses. By analyzing the characteristics and needs of the management course, combined with the requirements and objectives of ideological education in the course, a set of integration strategies including course objectives, content setting, teaching methods, etc. has been proposed. In practice, the comprehensive improvement of students' ideological and moral literacy and management ability can be promoted through case teaching, discussion classes, practical activities, and other methods. At the same time, this article also introduces relevant measures in curriculum evaluation and teacher team building to ensure the realization and sustainable development of integration effects. Through exploring the construction path of management courses and taking the integration of ideological elements into the curriculum as the starting point, this paper deeply analyzes the inherent connection between management and ideological theory, as well as the challenges and solutions that may be encountered during the integration process. Through case analysis and literature review, a series of feasible paths and methods have been proposed, aiming to promote the organic integration of management and ideological theory, and provide reference and inspiration for improving the quality and effectiveness of university education.

Water conservancy construction projects involve the use and management of natural water resources through artificial means to meet the needs of human society for water use and security. These projects encompass flood control and disaster mitigation, water supply, irrigation, hydropower generation, navigation, ecological protection, and other aspects. They are a vital part of national infrastructure, significantly contributing to socio-economic development and safeguarding people's lives and property. With the continuous increase in national investment, the management level of these projects is also improving.Auditing water conservancy construction projects involves reviewing and supervising their authenticity, legality, and effectiveness. It is a crucial component of project management. This paper draws on years of practical experience in auditing water conservancy projects, clarifying the audit methodologies and addressing common issues. It conducts in-depth research and analysis of typical problems and proposes a series of countermeasures and suggestions. These aim to enhance audit verification capabilities, better fulfill audit supervision duties, and promote the high-quality development of water conservancy construction project audits.
