Introduction: WHO estimated that uncorrected refractive errors are the leading cause of visual impairment and second leading cause of blindness globally. University students are prone to developing refractive errors due to their curriculum that requires a lot of near work affecting their performance and quality of life unknowingly. Genetic and environmental factors are thought to play a role in the development of refractive errors. This study addresses the paucity of knowledge about refractive errors among university students in East Africa, providing a foundation for further research. Objectives: To determine the prevalence and factors associated with refractive errors among students in the Faculty of Medicine at Mbarara University of Science and Technology. Methodology: This was a cross-sectional descriptive and analytical study in which 368 undergraduate students selected using random sampling were assessed for refractive errors from March 2021-July 2021. Eligible participants were recruited and their VA assessment done after answering a questionnaire. Students whose VA improved on pin hole had subjective retinoscopy and results were compiled and imported to STATA 14 for analysis. Results: The prevalence of refractive errors was 26.36% with (95% CI) among university students especially myopia. Myopia is most predominant at 60%, followed by 37% Astigmatism and hyperopia of 3% among medical students. Astigmatism consisted of largely myopic astigmatism 72% (26) and 28% (10) compound/mixed astigmatism only. Student positive family history of refractive error was found to have a statistically significant relationship with refractive errors with AOR 1.68 (1.04 - 2.72) (95% CI) and P (0.032). Conclusion: The prevalence of refractive errors among university students, especially myopia, was found to be high and family history was associated with students having refractive errors.

首届中美高等教育校长峰会共设三个圆桌会谈,第一圆桌会谈以“中美之间高等教育合作”为主题,邀请昆山杜克大学常务副校长denis simon,宾大沃顿商学院中国中心主任*** Zhang,帕森斯设计学院时装学院前院长simon Collins参与会谈。主持人:是什么吸引了美国杜克大学来到中国昆山市联合承办一所独立型大学?昆山杜克大学常务副校长丹尼斯·西蒙博士(denis simon):谈到美国杜克大学要来中国昆山市合办昆山杜克大学,原因有以下几点。我们首先考虑的就是市场规模,2017年有34000多名学生申请美国的杜克大学,但是只有310 0多名学生被录取。所以,对于中国来说,尽管杜克大学的教育非常好,但是国内每年也只有有限的学生进入杜克学习。这存在着很大的录取空间,昆山杜克大学能够很好的填补录取空余。其次,便是美国杜克大学的优质教育和课程设置。美式通识教育来到中国,培养学生的批判式思维、实践能力以及思维模式,也带来学术交流和文化交流。交流是双向的过程,昆山杜克大学的发展将反哺于美国杜克大学。最后,我认为也是最重要的原因,全球化的进程中,所有的国家都在寻找国际化的人才,中国也不例外。国家的发展还是靠人才,中国本土的高等教育发展也取得了很大的成果,中美联合办一所大学,有利于两个国家的高等教育成果共享,培养国际化人才,也为昆山市当地培养城市发展需要的人才。

Widely used bioaerosol generators like Collison nebulizer probably produce electrostatically charged par- ticles, but the electrical charges carried by laboratory-generated airborne microorganisms using bubbling aerosolizers are poorly understood. In this study, we measured the fraction of neutral particles and num- ber of elementary charges per particle as a function of the aerodynamic diameter of airborne bacteria （Escherichia coli and Enterococcus hirae）. Bioaerosols were produced by a liquid sparging aerosolizer-type bubbling generator, with particle sizes ranging from roughly 0.6 to 2 p^m. The experimental setup included an electrostatic precipitator and real-time devices including an electrometer, aerodynamic particle sizer, and electrical low-pressure impactor. Experimental results obtained for various operating conditions showed that aerosols produced with a higher bubbling airflow contained a larger proportion of neutral particles （from around 30% to 50%） and that bacteria carried a greater average absolute number of elementary charges （from around -10 to -60 elementary units） than those under lower airflow. Under the investigated conditions, a neutralization step is unnecessary because it may have a negative effect on the viability of sensitive microorganisms. Our results suggest that the neutral fraction can be used down- stream of an electrostatic precipitator, and that this setup may have advantages over bipolar neutralizers.

Tungiasis is an ectoparasitic skin disease caused by the penetration of the female sand flea, Tungapenetrans, into the epidermis of the host. Through an intensive literature review, poor hygiene, poverty, social neglect, ignorance, and poor cultural beliefs were found to promote jigger infestation in Kenya. The research revealed the vicious cycle of poverty, low educational standards, low self-esteem/stigmatization, violation of civil rights, HIV/AIDS and secondary infections as the effects of the infestation. Fumigation, on-host treatment of animals, proper hygiene, and health education are the suggested control measures. Generally, one needs to be physically, emotionally and socially sound to appropriately deliver the much needed services of national development. The jigger infestation negatively impacts on these aspects of human health, hampering the wholesome participation in nation building by both the infected and the affected. As a country, the Jigger menace is frustrating Kenya＇s attempts to achieve the Millennium Development Goal on poverty reduction by the year 2015, as well as reducing the pace of national development.
