摘要： PurposeTraditional payment systems based on cash and bank cards are being replaced by new innovative formats. This research analyzes the success factors in the adoption by customers of Bizum, a peer-to-peer (P2P) mobile payment system widely used in Spain. This study proposes a theoretical framework based on the Stimulus-Organism-Response (S-O-R) model and includes the analysis of the moderating effect of perceived risk and the mediating effect of perceived ***/methodology/approachTo achieve the proposed objectives, an online questionnaire was administered to 701 Spanish smartphone users, potential users of the proposed P2P payment *** results show that perceived usefulness is the most important predictor of intention to use.

关键词： 集束化营养护理   认知干预   腹腔镜胃癌根治术   疼痛   炎症反应   胃肠功能  

摘要： 分析集束化营养护理联合认知干预对腹腔镜胃癌根治术后胃肠道功能的影响。方法 选取2023.11-2024.10月期间到本院接受胃癌根治术进行治疗的患者100例,将其设为研究样本。使用随机数字表法将100例样本进行分组,常规组50例,组内患者进行常规干预,研究组50例,组内患者进行集束化营养护理联合认知干预,干预后将两组患者的术后疼痛、炎症反应及胃肠功能等指标进行分析对比。结果 研究组术后24小时及48小时VAS疼痛评分分别为(4.2±0.7)分和(2.1±0.5)分,显著低于常规组的(5.8±0.9)分和(3.7±0.6)分(均p<0.01);术后3天炎症指标检测显示,研究组血清CRP、IL-6、TNF-α水平分别为(28.4±5.2)mg/L、(45.3±6.8)pg/mL、(32.1±4.9)pg/mL,均低于常规组的(38.7±6.1)mg/L、(62.5±7.4)pg/mL、(48.6±5.7)pg/mL(均p<0.05);胃肠功能恢复方面,研究组首次排气时间(38.5±6.2h)、肠鸣音恢复时间(14.3±2.8h)及流质饮食耐受时间(56.4±7.9h)均较常规组(52.7±8.1h、21.6±3.5h、72.9±9.3h)显著缩短(均p<0.01);术后并发症发生率研究组为8.0%(4/50),明显低于常规组的26.0%(13/50)(p=0.015),其中研究组腹胀、恶心呕吐及肠梗阻发生率分别为4.0%、2.0%、2.0%,常规组对应为14.0%、8.0%、4.0%。结论 集束化营养护理联合认知干预可有效促进胃癌根治术患者术后康复,通过降低疼痛感知、减轻炎症反应、加速胃肠功能恢复并减少术后并发症,展现多维度协同干预优势。该护理模式通过优化营养支持与认知调节,可能改善患者围术期应激状态及胃肠动力障碍,为缩短术后恢复周期、提升治疗安全性提供有效路径,具有临床推广价值。

摘要： 探究对脑出血患者实施肢体功能训练护理对提高其恢复效果以及生活自理能力的影响。方法 从2024年1月至2024年12月间任意筛选60例脑出血确诊对象到研究中作为观察对象,经双盲法分组,对照组30例对象接受常规干预,观察组30例对象则接受肢体功能训练干预,对比两组对象身体恢复情况。结果 参与研究前所有对象的日常生活能力(ADL)和运动功能(Fugl-Meyer)差别不突出(P>0.05),干预后15d、30d时观察组评分居对照组之上(P<0.05)。在对两组对象的生活质量状况展开对比时,观察组中评分居对照组之上(P<0.05)。对比两组对象对于临床所提供的护理质量满意度时,观察组满意度居对照组之上(P<0.05)。结论 在对脑出血患者制定的护理方案中推行肢体功能训练干预能够有效提高患者身体恢复速度,提高其自身的生活自理能力,有利于提高患者生活质量和护理满意度。

关键词： forced zero-crossing   LC high-frequency oscillatory circuit   peak current limiting   ultra-high speed vacuum circuit breaker  

摘要： Excessive short-circuit current in distribution networks of industrial and mining enterprises is one of the most severe threats to the stable operation of equipment. To address this issue, an electrical circuit comprising an LC series circuit connected in parallel with the main circuit breaker is proposed, generating a current frequency of approximately 1.3 kHz. The high-frequency current flows through the main circuit breaker along with the system short-circuit fault current, forcing the short-circuit current to reach zero earlier and enabling a short-circuit current-limiting strategy in a vacuum condition. The proposed strategy incorporates an ultra-high-speed vacuum circuit breaker with an opening time of less than 1.2 ms, and a parallel LC high-frequency oscillatory circuit as a forced zero-crossing unit. This setup allows the main circuit to be rapidly interrupted, while a current-limiting reactor is subsequently introduced to effectively suppress the short-circuit current. Furthermore, this paper provides a detailed analysis of the operating mechanism of the current-limiting device, key parameter design, and its potential application in real-world distribution networks. Simulation and experimental validations demonstrate that the proposed current-limiting device can limit the short-circuit peak to below 70% of the actual value, thereby significantly reducing the peak short-circuit current, mitigating the adverse impact on distribution network equipment, and substantially enhancing the overall system operational stability. © 2025 Power System Protection and Control Press.
