Background: Breast cancer is the dominant cancer in women in both developed and developing countries. The objective of this study was to assess the knowledge, attitudes, practices and factors associated with early breast cancer screening among women in the municipality of Abomey-Calavi in Benin. methods: This was a cross-sectional, descriptive, analytical study with prospective data collection from October 1 to 8, 2018, involving 1740 women in the municipality of Abomey-Calavi, aged 18 years or older and selected by WHO four-stage random cluster sampling. Consenting women who were mentally competent, 18 years of age or older at the time of the survey, and residing continuously in the municipality of Abomey-Calavi for the last six months prior to the survey were included. On the other hand, women who belonged to a breast cancer prevention service, women in whom secondary screening was noted, or non-consenting women were not included. The initial minimum size was estimated by the Schwartz formula with a cluster effect of k = 2. Information was collected by questionnaire survey, entered with Epidata 3.1. Fr and analyzed with R Studio 3.5.1. software. Results: The mean age of the women surveyed was 32.0 ± 11.5 years with a range of 18 and 71 years. Regarding knowledge, the clinical manifestation known by the majority of women was the presence of a nodule (68.50%). In the series, 1308 (75.17%) declared having heard about breast cancer once before, either on the radio, television or from friends and 726 (55.50%) had heard about breast cancer screening. Five hundred and twelve (70.52%) of the 726 who had heard of breast cancer said they knew that breast cancer could be screened earlier. Breast self-examination was the most cited screening method (67.58%). The disease is of natural origin according to 37.84% of them. Regarding attitudes and practices, the prevalence of early breast cancer screening was 12.93%, of which 11.67% declared that they had checked them.elves to kno

Background: There are few studies on the cost of glaucoma management in developing country, especially in Togo, there are no data on the cost of POAG management. Aims: To determine the annual direct cost of the management of POAG, to evaluate the annual economic weight of the management of POAG and to determine the factors associated with the annual economic weight of the management. methods: We conducted a retrospective and descriptive study over a period of 12 months from January 1 to December 31, 2019 based on the records of patients followed for POAG in AFIA Eye Clinic in lomé-Togo. The annual direct cost was defined by the sum of the costs of consultations, explorations and treatments. We defined the direct cost per patient and per year and related to the average annual income. It was said to be catastrophic at 20% or more of the estimated annual income. Chi 2 and Fisher tested the comparison of proportions. We conducted univariate and multivariate logistic regression to search correlations. Results: During the study period, 150 patient records were included. The average age was 47.24 ± 17.09 years and the sex ratio was 0.82. The cost of the diagnosis was 112.18 ± 22.26 €. The average cost of consultations was 19.46 ± 11.35 € and that of explorations was 92.71 ± 10.91 €. The annual cost of treatment per patient was 165.52 ± 110.16 €. The annual global direct cost of POAG management per patient was 277.69 ± 132.42 €. Compared to the annual income of 1166.29 €, the economic weight of the glaucoma management was 23.8%. This direct cost was catastrophic for 32.1% of patients in the study (44/150 of people with no care). Compared to the guaranteed inter-professional minimum wage (SmIG) of 640.30 €, the economic direct cost weight was 43.3%. Risk factors significantly associated with the direct cost were age over 40 (OR = 1.05 and p = 0.032), liberal profession (OR = 4.72 and p = 0.04), the absence of health insurance (OR = 6.68 and p = 0.017) and the use carbonic an

为解决X射线底片焊缝缺陷分割精度不高、边界信息模糊的问题,本文提出一种改进的Dilated_Pooling_Unet(DP_Unet)网络分割模型。首先,在上下采样间加入编解码信息提取模块DP_block,旨在下采样后最大限度地保留原始缺陷语义信息及减少连续卷积与池化操作造成的损失;然后,在模型中添加gam注意力机制重点关注焊缝缺陷部分,有效提升缺陷特征通道的学习能力,降低背景噪声影响;最后,提出一种融合二元交叉熵和Diceloss的混合损失函数,用于解决网络训练时不均衡的正负类数据问题。实验数据集由公开数据集GDX-ray缺陷数据集组成。实验结果表明,本文所提方法在GDX-ray数据集上有较好表现,Dice值达到了93.45%,与基线算法相比均有显著提高。该方法具有良好的分割性能,优于传统的分割算法,有效提高了底片焊缝缺陷分割精度。

Contribution of the large Helical Device Plasmas to Alfvén Eigenmode Physics in Toroidal Plasmas

Plasma Science and Technology 2009年第4期11卷 377-380页

In the large helical device （lHD） having three dimensional configuration, Alfven eigenmodes （AEs） destabilized by energetic ions are widely investigated using neutral beam heated plasmas with monotonic and non-monotonic rotational transform （l/2π） profiles. In a plasma with monotonic l/2π-profile, core-localized toroidicity-induced Alfven eigenmode （TAE） as well as global one are often observed. With the increase in the averaged toroidal beta value, defined as the ratio of total plasma pressure to toroidal magnetic pressure, core-localized TAE with low toroidal mode number becomes global. In a relatively high beta plasma with monotonic l/2π-profile, two TAEs with different toroidal mode number often interact nonlinearly and generate another modes through three wave coupling. In a plasma with non-monotonic l/2π-profile generated by intense counter neutral beam current drive, reversed shear Alfven eigenmode （RSAE） and geodesic acoustic mode （CAm） excited by energetic ions were observed for the first time in a helical plasma. Nonlinear coupling was also observed between RSAE and gam.

Purpose: To assess the effects of monocular lid closure during critical period on cortical ***: Pattern visual evoked potentials (PVEP) of the normal and the monocular deprivation (mD) cats were dynamically measured and the number of gam-maaminobutyric acid immunopositive (GABA-IP) neurones of the area 17 of the visual cortex and the lateral geniculate nucleus (lGN) was quantitatively compared by using immunohistochemical method (ABC).Result: The amplitude of the N1-P1 attenuated in deprived eyes (DE) , NE/DE at postnatal week (PNW) 7-8 (P<0. 05), NE/DE at PNW 15-16 (P<0. 01); while P1 latency delayed, NE/DE at PNW 7-8 (P>0. 05), NE/DE at PNW 15 - 16(P<0. 05). The numbers of GABA-IP neurones in layer A1 of the ipsilateral lGN and in layer A of the contralateral lGN, compared to those in the corresponding normal laminae, were not significant at PNW 7 - 8 and PNW 11 - 12 (P >0. 05), while in the same cats a reduction in the number of GABA-IP neurcnes was found in layer IV of area 17 at PNW

针对湖南省臭氧(O_(3))污染加剧但是相关的研究较为缺乏的现状,以长沙市为研究区域,基于观测数据,结合气象校正、基于经验的模型(EOF)和绝对得分受体模型(APCs),识别量化了2018~2020年气象、本地光化学生成和外围传输对O_(3)污染相对贡献的影响,分析了2018~2019年和2019~2020年O_(3)趋势变化的主控因素.结果表明,短期范围内,气象条件是O_(3)污染事件发生的重要诱发因素.对长沙市整体来说,在时间上,2018~2019年期间,气象和本地前体物排放影响作用的增强是O_(3)浓度升高的关键驱动因子.2019~2020年期间,气象、本地前体物排放和外围传输影响均呈现下降的趋势,是导致O_(3)浓度降低的重要影响因素.空间上,2018~2020年时间段,气象、本地前体物排放和外围传输主要影响区域分别为长沙市偏东、偏北和偏南部区域.其中,外围传输的作用持续减弱,2018~2019年期间,长沙市北部天然源排放水平的升高使得O_(3)浓度上升,南部区域NO_(x)排放量升高导致滴定作用加强,使得O_(3)浓度降低,在此期间气象条件对整个区域的影响作用增强.2019~2020年期间,本地前体物排放水平不同的变化趋势使得对长沙市O_(3)浓度的影响与2018~2019年状况相反,在此期间气象条件的影响作用减弱.
