Introduction: Musculoskeletal disorders (MSDs) are a set of peri-articular conditions that result mainly in pain and functional discomfort. They represent a major occupational health problem in all areas of activity. The objective of this work was to determine the prevalence of MSDs among street vendors in the city of Bangui in the Central African Republic (CAR). Methods: A cross-sectional study was conducted from September 01 to October 31, 2021 in Bangui, the capital of CAR. The study population consisted of street vendors which were included at the entrance of 4 large markets of Bangui after giving informed consent. The sample size, calculated according to the Schwartz formula, was 384. Sociodemographic data (age, gender, level of education, marital status), professional data (the duration of sale in hours, the distance traveled per day);and health data (the health problems suffered by itinerant sellers and the means of dealing with them) were collected using a pre-established self-questionnaire. This collected data was processed using Microsoft Excel 2013 and Epi-Info version 7 software. Results: Among 384 street vendors included, women represented a quarter (24.9%). The average age was 27 years;the 25-34 age group was the most represented (50%). About two-thirds (64.8%) sold for at least 12 hours and traveled more than 10 km (69.3%) per day. The main health problems reported by street vendors were musculoskeletal disorders (95.8%). Their locations concerned the upper limbs shoulder 65.36% (251), elbow 24.22% (93). Non-ergonomic postures that stress the back and joints all day long, causing pain are risk factors for MSDs. These MSDs were treated by self-medication with non-steroidal anti-inflammatory drugs (22.0%), mainly sold on the street. Conclusion: MSDs dominated the health problems of street vendors. These problems raise the need for recognition and support for these workers to optimize their performance while preserving their health through awareness and

A wireless communication system can be tested either in actual conditions or by using a hardware simulator reproducing actual conditions. With a hardware simulator it is possible to freely simulate a desired type of a radio channel. This paper presents architectures for the digital block of a hardware simulator of MIMO (multiple-input multiple-output) propagation channels. This simulator can be used for LTE (long term evolution system) and WLAN (wireless local area networks) 802.11ac applications, in indoor and outdoor environments. The first architecture is appropriate for shipboard environments, while the second corresponds to outdoor-to-indoor environments and considers the wave propagation penetration within buildings. Measurements campaigns carried out at 2.2 and 3.5 GHz have been conducted to obtain the impulse responses of the channel using a MIMO channel sounder designed at IETR. The measurements are processed with an algorithm extracting the dominant paths. The architectures of the digital block are implemented on a Xilinx Virtex-IV FPGA (field programmable gate array). After the implementation of the impulse responses, the accuracy, the occupation on the FPGA and the latency of the architectures are analyzed.

基于词空间的分类方法很难处理文本的高维特性和捕获文本语义概念.利用核主成分分析和支持向量机,提出一种通过约简文本数据维数抽取语义概念、基于语义概念进行文本分类的新方法.首先将文档映射到高维线性特征空间消除非线性特征,然后在映射空间中通过主成分分析消除变量之间的相关性,实现降维和语义概念抽取,得到文档的语义概念空间,最后在语义概念空间中采用支持向量机进行分类.通过新定义的核函数,不必显式实现到语义概念空间的映射,可在原始文档向量空间中直接实现基于语义概念的分类.利用核化的gha方法自适应迭代求解核矩阵的特征向量和特征值,适于求解大规模的文本分类问题.试验结果表明该方法对于改进文本分类的性能具有较好的效果.

目的了解胃肝样腺癌(gha)的研究现状,以期为临床诊治提供参考。方法查阅近年来国内外关于gha研究的相关文献并进行综述。结果 gha是一种具有腺样分化和肝细胞分化的特殊类型胃癌,在所有胃癌中发生率≤1%。gha的组织学形态与肝细胞癌相似,常伴有血清甲胎蛋白升高,极易出现淋巴结转移和肝转移。根治性手术及化疗是其最主要的治疗方法,但即使是根治性切除后仍常见复发和转移,且目前尚无针对gha的标准化疗方案。结论 gha是一种恶性度较高的特殊胃癌亚型,临床进展迅速,预后差。组织病理学结果是诊断gha的金标准。gha治疗以手术与化疗为主的综合治疗方式,基因分子特征及靶向治疗是未来的研究方向。
