Methods: A total of 60 patients who underwent thoracoscopic pulmonary nodule resection in the Department of Thoracic Surgery of our hospital from May 1, 2023 to April 30, 2024 were selected and randomly divided into control group and experimental group by random number method. The control group applied traditional health education mode, and the experimental group applied digital interactive video multimedia education mode on the basis of traditional education. The changes in computer adaptive score, Amsterdam Preoperative Anxiety and Information Score (APAIS), basic physiological indicators and satisfaction were compared between 1 day before surgery and the day of surgery in 2 groups. Results: Compared with before intervention, scores of education content, preoperative preparation and postoperative cooperation were increased after intervention (P < 0.05), and scores of experimental group were significantly higher than those of control group after intervention (P < 0.05). Compared with before intervention, scores of anesthesia-related anxiety, surgery-related anxiety and information need were all decreased after intervention (P < 0.05), and scores in the experimental group were significantly lower than those in the control group after intervention (P < 0.05). Compared with before intervention, the systolic blood pressure, diastolic blood pressure and heart rate were all decreased after intervention (P < 0.05), and after intervention, all indexes in the experimental group were significantly lower than those in the control group (P < 0.05). After intervention, the satisfaction of experimental group was 93.33%, and that of control group was 73.33%;the difference was statistically significant (P < 0.05). Conclusion: Digital interactive video education can improve the computer adaptive score of thoracoscopic pulmonary nodule resection patients, reduce Amsterdam Preoperative Anxiety and Information Score (APAIS), reduce basic physiological indicators and improve satisfaction, which is worthy of clinical promotion.展开更多

Computer-aided overlay was conducted to classifyRSR types. The evaluation was carried out by using three methods, i.e., index summation, square root ofindex multiplication and fuzzy comprehensive assessment, with almost identical results. The result of indexsummation could represent the basic qualitative condition of RSR, that of square root of index multiplicationreflected the real condition of RSR qualitative rank, while fuzzy comprehensive assessment could satisfactorilyhandle the relationship between the evaluation factors and the qualitative rank of RSR, and therefore it is afeasible method for RSR evaluation.展开更多

The assessment process of the GIS based map overlay method was presented, which includes deciding the system structure and weights of assessment factors, making environmental vulnerability grade maps, and evaluating the alternative alignments comprehensively to obtain the best one. With the GIS functions of spatial analysis, such as overlay analysis and buffer analysis, and functions of handling attribute data, the GIS based map overlay method overcomes the shortcomings of the existing map overlay method and the conclusion is more reasonable. In the end, a detailed case study was illustrated to verify the efficiency of the method.展开更多

It plays an important role, especially in terms of food security for not only Vietnam but also the world. However, the Vietnamese Mekong Delta is projected to be heavily affected by： （1） the annual （fluvial） flood, which would be changed in terms of time and spatial distribution after impacts of climate change scenarios （i.e., sharper hydrograph with shorter flood period）; and （2） sea level rise. Such combination would result in significant changes of surface water resources, leading to consequent impacts on the existing fanning systems in the Vietnamese Mekong Delta. Therefore, this paper presents a new approach of integrating a one-dimensional hydrodynamic model （ISIS-1 D） with GIS （Geographic Information System ） analyses to： （1） identify priority areas for flood adaptation and mitigation; （2） provide an insight to local decision-makers in the Vietnamese Mekong Delta in changes of future floods.展开更多
