随着信息技术、互联网技术的快速发展,短视频作为一种基于移动互联网的“信息+体验+场景”模式,受到人们广泛关注,短视频的蓬勃发展使人们的信息获取方式发生了深刻改变。当今时代,不少人借助各类短视频助力城市文化传播和城市形象构建,构建不同的城市场景,提高城市能见度和对外形象。文章采用案例研究、文本分析等方法,归纳短视频塑造的城市文化形象,基于短视频在城市文化传播中的艺术分析,剖析基于短视频的城市文化传播存在的问题,如传播内容存在同质化倾向、传播方式相对单一、传播渠道较为狭窄等。当前,短视频城市文化传播尚需多元主体协同发展,合力打造短视频城市文化传播矩阵,整合各方资源运营城市IP,以塑造出立体、多元的城市文化形象。基于此,文章从短视频传播内容、传播方式、传播渠道等不同维度,提出基于短视频的城市文化传播策略:丰富短视频文化传播内容,如凝练城市文化传播内核等;注重短视频文化传播的多元化,如运用设计符号提炼城市的视觉表达等;拓宽短视频文化传播渠道,如多渠道构建传播矩阵等。文章认为,多层次、多角度地讲述城市故事,重塑城市文化形象,能更好地助力城市文旅全产业链升级,并为其他地区的城市文化短视频传播提供理论范式。

Objectives: To demonstrate the contribution and relevance of ETFs through the study of 1000 examination reports carried out in the medical imaging departments of the OUAGADOUGOU CHU. Material and method: Analytical descriptive study with retrospective collection, extended from 1st January 2020 to 1st January 2022. Results: Of the 1000 transfontanellar ultrasound reports, the mean age of patients was 7.61 +/ 7.5 days, with extremes of zero and 28 days. Sex was specified in 989 cases. Males accounted for 54.49% and females for 45.51%. 555 transfontanellar ultrasound were performed in 2020. 441 in 2021 and 4 in 2022. 61.9% of transfontanellar ultrasound were performed at the Bogodogo University Hospital, 205 at Charles de Gaulle and 176 at Tengandogo. Indications for transfontanellar ultrasound were dominated by neonatal distress (65.8%), followed by convulsions (10.2%) and prematurity (9.1%). Transfontanellar ultrasound was normal in 570 cases (57%) and abnormal in 430 cases (43%). Abnormalities were dominated by haemorrhage and ischaemic lesions in 66.28% (285) and 21.63% (93) of cases respectively. In the group of normal transfontanellar ultrasound, neonatal distress represented 59.65% of indications and prematurity 10.7% of indications. As for abnormal transfontanellar ultrasound, neonatal suffering accounted for 73.95% of indications and convulsions for 12.56%. The average age ofpatients with an abnormal transfontanellar ultrasound was 8.74 days +/ 7.89 days. The indication for investigations was relevant in 42.2% of cases and irrelevant in 57.8%;of the transfontanellar ultrasound with relevant indications, 0.71 were normal and 99.29 abnormal;of the transfontanellar ultrasound with irrelevant indications, the transfontanellar ultrasound was normal in 98.1% and abnormal in 1.9%. Conclusion: Transfontanellar ultrasound is an important part of ultrasound in current practice. Haemorrhage, anoxic-ischaemic lesions and hydrocephalus are the most frequent pathologies fou

Introduction: Urinary lithiasis is defining as a condition characterized by the formation of concretions in the kidneys or urinary excretory tract. We aimed to study professional practice in CT urinary lithiasis at CHUYO. Materials and method: This was a descriptive cross-sectional study with retrospective data collection covering 3 years from January 2017 to December 2019. Results: In general, it was noted that CT scans in our environment provide all the elements needed by urologists to diagnose urinary lithiasis and its impact on the urinary system. However, there are shortcomings, particularly in terms of the accuracy of the shape and density of the stones in the CT scan reports, which does not make it easier for urologists to decide on treatment. Conclusion: Computed tomography plays a major role in the diagnosis and therapeutic management of urinary lithiasis, and its use needs to be improved in our context.
