拟探索在AIGC背景下智慧教学设计的范式,以艺术设计类教学为视角,基于梅耶多媒体学习理论构建新的智慧教学设计模型,旨在于推动学生实现可持续发展的生成式学习。数据收集采用问卷调查法,并使用Smartpls软件进行PLS—SEM模型分析研究。研究结果显示,影响智慧教学设计的两大维度分别是认知因素和情感因素,证明了情感与动机是直接影响学生可持续发展生成式学习的重要因素,并提出以下设计策略:第一,认知管理是可持续发展生成式学习的地基石;第二,情感动机是可持续发展生成式学习的助推剂;第三,自主学习是可持续发展生成式学习的内动力。深刻把握AIGC技术中的艺术设计原理及其赋能智慧教学的耦合机制,让AIGC技术成为智慧教学设计的重要助力。

化石有机碳风化是地质时间尺度上重要的碳源,对全球碳循环和气候变化具有重要影响,但如何量化一直是个挑战.河水铼(Re)含量的变化被认为具有示踪流域化石有机碳风化强度的潜力,然而Re的来源及其与化石有机碳风化之间的关系还知之甚少.为了更好地认识这一指标的有效性,本文选择重庆市城口县下寒武统水井沱组页岩风化剖面为研究对象,通过元素含量、逐级提取实验等分析,探讨页岩风化序列中Re和硒(Se)的活动性及其与化石有机碳风化的关系.结果表明,化学蚀变指数(CIA)从基岩到风化层逐步升高,指示增强的风化强度.根据逐级提取实验和质量迁移系数(τ)的变化发现,页岩中的Re和Se主要赋存于有机质相,风化过程中与化石有机碳同步流失,而与页岩中的硫化物矿物氧化无明显相关;风化过程中Re和Se不同的地球化学行为导致其与化石有机碳非等量流失.本研究支持Re作为示踪化石有机碳风化的指标,而Se是示踪化石有机碳风化的潜在指标.未来需要不同类型沉积岩剖面与流域相结合的研究,明确河水Re和Se的来源及其与流域化石有机碳风化之间的关系.

Introduction: Acute rheumatic fever (AAR) is a non-suppurative complication of late infection by group A. Infections due to streptococci remain a public health problem in the Central African Republic. The present study aims to determine the incidence rate of AAR cases and its complications. Methodology: This was a retrospective and analytical study over a period of 4 years (from January 2015 to December 2018) at the National Laboratory of Clinical Biology and Public Health (LNBCSP) in Bangui. It focused on samples concerning the diagnosis of AAR and patient files seen in consultation in the capital’s reference health establishments. Laboratory registers and patient consultation files were used to collect data. They were entered into Excel 2010 to be analyzed with Epi Info 7. A univariate analysis by logistic regression, Ficher’s exact test, and chi2 at the 5% threshold (p Results: We analyzed 94 cases meeting Jones’s criteria. The ages of the patients ranged from 18 to 85 years (mean age 52 years and mode 45 years). The incidence rate of AAR for the female sex was higher than that of the male sex during the study period (p > 0.05). It went from 166.6 in 2015 to 200 in 2016 and 2018 cases of AAR per 1000 people per year. The average incidence rate was 296.18 cases of AAR per 1000 people per year. The average incidence rate was 223.5 cases of AAR per 1000 people per year for joint damage. Joint damage represented 80.85% (RR = 0.62;Chi2 = 4.88;95% CI [0.39-0.97];p Conclusion: The study allowed data on the impact rate and complications of the AAR in Bangui. Special attention to data management will help produce a complete result on the problem. Joint complications predominated. Sustaining an effective surveillance system and preventing infection would help reduce the risk of AAR occurrence.
