Abstract: The rapid advancement of diagnostic and interventional techniques in pulmonary medicine has created substantial challenges for conventional training approaches, including short-term clinical rotations and traditional mentor-apprentice models, which are often hindered by limited case exposure, inconsistent teaching standards, and a lack of accessible self-directed learning resources. To address these issues, this study—supported by an institutional grant—developed a specialized digital educational repository for interventional pulmonology. Utilizing the departmental WeChat official account as a mobile-friendly online platform, we curated a diverse array of instructional materials, comprising standardized textbooks, high-definition procedure videos, representative complex cases, and topic-focused micro-lectures. A structured online curriculum was subsequently delivered to trainees in standardized specialty training, and its effectiveness was quantitatively assessed via periodic online examinations. A total of 99 medical staff who participated in the training between March and August 2025 were recruited and categorized based on their learning mode into a systematic learning group (Group A, n=59) and a self-directed fragmented learning group (Group B, n=40). Results demonstrated that Group A attained a mean score of 100.97 with an accuracy rate of 97.00%, whereas Group B scored a mean of 20.75 with an accuracy of 58.20%. The systematic learning group exhibited significantly superior performance in both learning engagement and theoretical knowledge acquisition compared to the fragmented learning group. The developed digital resource library offers standardized, modular educational content that markedly enhances the quality of specialized training in interventional pulmonology. Furthermore, given its low construction and maintenance costs, this approach is highly reproducible and holds considerable potential for broader adoption across respiratory medicine departments in healthcare institutions at all levels.

Abstract: The simple pendulum formula is widely used in introductory physics laboratories to determine the gravitational acceleration. However, this formula assumes a point mass and a massless string, an idealization that fails when the pendulum bob has a finite size. This paper introduces the concept of an equivalent length such that the simple pendulum formula exactly reproduces the correct period of a physical pendulum consisting of a uniform spherical bob and a light string. Using elementary rigid-body dynamics, we derive an analytical expression for the correction factor, which depends only on the ratio of the string length to the bob radius. Numerical calculations over a wide range of this ratio show that the correction is below 0.5% when the string length is at least ten times the bob radius, but exceeds 4% when the ratio is two. A detailed lookup table and a classroom procedure are provided, allowing students to continue using the familiar simple pendulum equation while obtaining accurate values of gravitational acceleration. This work bridges the gap between idealized models and real physical systems without requiring advanced mathematics. The approach is purely computational and requires no laboratory equipment, making it suitable as a pre-lab exercise, a classroom demonstration, or an independent student project in numerical methods. By preserving the simple pendulum equation, the method reduces cognitive load and provides a natural bridge to more advanced topics such as moment of inertia and the parallel axis theorem. The results are exact within the stated assumptions and offer immediate practical utility for both high school and introductory university teachers.Abstract: The simple pendulum formula is widely used in introductory physics laboratories to determine the gravitational acceleration.

Abstract: The construction of Emerging Engineering Education raises higher educational requirements for advanced information literacy of students majoring in chemical engineering. This study aims to construct an integrated teaching system centered on advanced scientific research capabilities, shifting the core teaching focus of the course from basic retrieval operation training to the systematic cultivation of comprehensive scientific research literacy. A teaching pilot was carried out on one class of general chemical engineering majors at Hongde College of Beijing University of Chemical Technology. Based on the Outcomes-Based Education (OBE) concept, the teaching scheme was optimized from four dimensions: integrated teaching combining Problem-Based Learning (PBL) and project-based learning, practical training centering on real chemical engineering research topics, comparative practical operation of AI retrieval tools, and in-depth integration of curriculum ideology and politics. The implementation effects were quantitatively evaluated by comparing students' course examination scores, achievements in science and innovation competitions, and outcomes of college students' innovation training programs before and after the pilot. The teaching pilot has effectively improved students' advanced scientific research capabilities including literature screening, identification and integrated innovation, enabling students to skillfully combine professional databases and AI tools to complete full-process scientific literature research. The proposed teaching path can improve the educational quality of literature retrieval courses and provide operable practical references for cultivating innovative research talents majoring in chemical engineering.
