Modern technologies involved in the education process have led to significant changes in the approach to the educational process. The development of information and communication technologies has enabled the emergence of various digital tools that can contribute to easier and more efficient transfer and acquisition of knowledge. The purposeful integration of digital tools into the teaching and learning process is a current issue in the education system. The fact is that students have different levels of prior knowledge and motivation, which gives digital tools the opportunity to contribute to the quality of education when used appropriately. In this paper, we analyze the use of personalized tools in the teaching and learning process.

The segmented operation mode of urban rail transit is prone to cause transfer congestion under high passenger flow, which not only degrades the passenger travel experience but also reduces transfer pressure, optimizes resource allocation, and cuts costs through interconnection and interline operation. This paper selects two intersecting lines forming a Y-shape as the research object, aiming to minimize the system cost consisting of "passenger travel cost" and "enterprise operation cost". Considering constraints such as maximum load factor, minimum tracking interval, and minimum departure frequency, a dual-objective optimization model for interline operation schemes is constructed, and a genetic algorithm is designed to solve the model based on its characteristics. Using passenger flow data from Beijing Subway's Changping Line and Line 8 as samples, the model is solved using MATLAB, and the results are compared with the operation scheme under the traditional single-line operation mode. The analysis shows that after scheme optimization, the total enterprise operation cost decreases by 9.6% compared to the original scheme, and the total passenger travel time reduces by 23%, effectively improving operational efficiency and service retention.

To address key challenges faced by the elderly during bathing—high risk of slipping, physical frailty, and the limited functionality of existing products—this study develops an elderly-oriented intelligent multifunctional assisted shower chair with safety assurance as its core design principle, incorporating anti-slip chair feet and seat surfaces made of specialized materials and integrating a lead-screw lifting armrest with an electric push-rod base plate to form a dual auxiliary standing system; for bathing functionality, the shower arm’s elevation and rotation are achieved through the combination of synchronous belt transmission and bevel gears, while an automatic foaming device installed under the armrest enhances cleaning efficiency. The intelligent control system employs a serial port screen for human-machine interaction, enabling automatic adjustment of water temperature and flow rate, and furthermore constructs a three-tier alarm mechanism linked with a buzzer, a guardian APP, and a property management system, thereby forming a closed-loop safety network. This "mechanical assistance-intelligent control-safety early warning" integrated design bridges the functional gap between passive support and active care, provides a technical paradigm for the development of aging-adaptable products, and is expected to be applied in domestic and nursing home settings, contributing to improved quality of life and independent dignity for the elderly.
