Abstract

To study direct drive pumping unit of operating state, permanent magnet synchronous motor open-loop control system was used to model and simulate based on Matlab/Simulink software, and analyzed the waveforms change with different torque. The results indicate that permanent magnet synchronous motor can operate smoothly under low speed and high torque condition, and can meet work requirement of direct drive pumping unit with acceleration. The proposed Simulink simulation system can achieve stable control in actual operation, and its effectiveness was confirmed experimentally. Results of simulation analysis have some certain practical value for pumping unit driven by permanent magnet synchronous motor. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4836

Abstract

Introduction: Traditional discharge education for inflammatory bowel disease (IBD) patients tends to be brief and one-way, often leaving gaps in knowledge, self-care, and emotional support. The LEARNS model, a structured and interactive health education programme, may be more effective in addressing these needs and improving patient outcomes. Objective: To assess the impact of a LEARNS-based nursing education program on anxiety, depression, self-care ability, disease knowledge, and health-related quality of life in patients with inflammatory bowel disease. Methods: In a randomized controlled trial conducted at a tertiary hospital in 2024, 120 adult IBD inpatients were randomly assigned to either 12 weeks of LEARNS-based education combined with standard care (n = 60) or to standard care alone (n = 60). We assessed anxiety (Zung Anxiety Scale), depression (Zung Depression Scale), self-care ability (ESCA), disease knowledge (CCKNOW), and quality of life (IBDQ) at baseline and after 12 weeks of intervention. Results: After 12 weeks, the LEARNS group showed significantly lower anxiety (27.2 ± 5.0 vs. 32.0 ± 6.2, p < 0.001) and depression (31.7 ± 7.6 vs. 36.8 ± 9.6, p = 0.012) scores. Additionally, the LEARNS group had significantly higher self-care scores (130.2 ± 17.3 vs. 117.8 ± 13.6, p < 0.001) and knowledge scores (15.6 ± 3.0 vs. 12.9 ± 2.6, p < 0.001). However, there were no significant differences between the two groups in quality-of-life scores (IBDQ) (p = 0.83). Conclusion: The LEARNS health education model significantly improved anxiety, depression, self-care, and disease knowledge in IBD patients over 12 weeks. However, there was no significant improvement in quality of life, which highlights the need for further studies with longer follow-up to explore the long-term effects of the intervention. Integrating this patient-centered education approach into routine clinical practice can provide enhanced support for patients, but future multicenter studies with extended follow-up are necessary to confirm the lasting impact on quality of life.
