Introduction: According to the World Health Organization, globally one in six people experience infertility in their lifetime. Infertility is considered as a major and global public health issue. In most cases, women bear the burden of infertility to protect the male ego. Although men and women are equally likely to have fertility problems. The aim of this study was to identify the causes of infertility of couples residing in Libreville. Patients and Methods: This was a retrospective descriptive study performed over 2 years, from 1st January 2021 to 31st December 2022. Data was obtained from 162 couples attending the assisted reproduction department of the mother and child hospitals in Libreville. Statistical analysis was done using IBM SPSS Statistics version 22.0 software. Results: During the study period, 28.5% of couples could afford IVF treatment. The average for woman age was 39.1 ± 4.06 while the average age for male patients was 41.53 ± 7.08 years with minimum and maximum age of 34 et 66 years. More than half (58.6%) of female partners were employed in the public sector. Half of the male partners (50%) were employed in the private sector. The median duration of infertility was 6 years. Approximately 49.4% of couples were diagnosed with primary infertility. The most common causes of infertility in female patients were Fallopian tubes obstruction (53.2%), uterine factors (24.2%) and hormonal problems (19.6%). With regards to male factors infertility, testicular causes were predominant (53.6%). Oligoasthenoteratozoospermia were the major semen abnormalities (55.7%) found after semen evaluation. Both male and female partners were sub-fertile in 47.5% of cases. Unexplained infertility was found in 11% of couples. Conclusion: This study showed that the diagnostic of infertility faced by couples residing in Libreville should involve both male and female partner.

人体运动是肢体运动方向、关节活动顺序以及动作幅度相互协调的过程.然而,现有方法往往直接对原始3D骨骼关节点信息进行建模,容易忽略肢体关节活动的顺序关系、运动方向性以及动作幅度变化影响.因此,提出一种顺序主导和方向驱动下基于点边特征的骨骼卷积神经网络,通过刻画人体关节点运动顺序、帧间距离和骨骼边方向向量等特征对人体动作分类识别.该网络包含顺序主导单元和方向驱动单元.顺序主导单元对骨骼边末端关节点进行建模,利用关节点的排列方式、帧间距离信息对关节活动顺序和肢体变化幅度进行表征.方向驱动单元利用骨骼边方向向量信息表征肢体运动的方向性.最后,将顺序主导单元与方向驱动单元进行特征融合,对人体日常行为动作进行分类识别.实验结果表明,在两个大型数据集NTU-RGB+D60和NTU-RGB+D120上的实验结果分别较基准方法提升了2.6%、3.5%和5.9%、6.1%.因此,所提出方法能有效利用多特征之间的协同互补性对人类日常行为运动进行深层次刻画,提高人体动作识别的精度.

Humanoid robots are designed and built to mimic human form and movement. Ultimately, they are meant to resemble the size and physical abilities of a human in order to function in human-oriented environments and to work autonomously but to pose no physical threat to humans. Here, a humanoid robot that resembles a human in appearance and movement is built using powerful actuators paired with gear trains, joint mechanisms, and motor drivers that are all encased in a package no larger than that of the human physique. In this paper, we propose the construction of a humanoid-applicable anthropomorphic 7-DoF arm complete with an 8-DoF hand. The novel mechanical design of this humanoid ann makes it sufficiently compact to be compatible with currently available narrating-model humanoids, and to be sufficiently powerful and flexible to be functional; the number of degrees of freedom endowed in this robotic arm is sufficient for executing a wide range of tasks, including dexterous hand movements. The developed humanoid arm and hand are capable of sensing and interpreting incoming external force using the motor in each joint current without conventional torque sensors. The humanoid ann adopts an algorithm to avoid obstacles and the dexterous hand is capable of grasping objects. The developed robotic ann is suitable for use in an interactive humanoid robot.

在数字帝国主义中,跨国数字垄断公司借助数字技术、数字平台、数据传输,结合国家政权在全球范围内攫取不发达国家的剩余价值。资本增殖逻辑下的资本竞争与资本垄断,是数字帝国主义的基本生成逻辑,金融资本与政治权力的加持则是数字霸权形成与扩张的必要条件。数字帝国主义通过控制全球生产过程、企业劳动过程、大众意识形态,以更加隐蔽但又强势的形态将数字弱国、数字劳动乃至数字用户改造成数字网络空间的节点,成为其攫取剩余价值的工具。面对数字霸权,首先要增强自主创新能力,加强关键核心数字技术的创新应用;其次应坚持以人民为中心发展数字经济,抵制数字强国意识形态入侵;最后要积极构建数字贸易合理规则,推动世界数字技术共建共享。
