This paper gives an overview of the evolution of city drainage in ancient China, and analyzes the achievement of drainage of such cities as Pingliangtai in Henan province, Xibo of Shang Dynasty, Linzi, the capital of the State of Qi, Chang'an, the capital of Han and Tang Dynasties, Kaifeng, the Eastern Capital of Northern Song Dynasty, Ganzhou, Dadu, the capital of Yuan Dynasty; and Beijing, the capital of Ming and Qing Dynasties. This paper also sums up the characteristics and the management experiences of the drainage facilities of ancient Chinese cities, including drainage system management methods, rules and laws about drainage in different eras, and overall principles of ancient city water systems. At present, most major cities in China are facing issues relating to drainage systems and city water systems. These cities are often bothered by floods and other water-related problems. Learning from the ancestors' experience would be important and necessary for modern planners and decision makers. Therefore this paper may be used for reference in modern city planning and construction.

Objetivo: Esse estudo objetivou investigar percepções de estudantes de Odontologia quanto ao medo e à ansiedade em relação ao manejo de pacientes e ao risco de infecção por COVID-19. Materiais e métodos: Esse estudo transversal envolveu todos os alunos regularmente matriculados em Odontologia, no primeiro semestre de 2020, da Universidade Federal de Pelotas. Um questionário foi aplicado, coletando dados demográficos, nível de formação e perguntas relacionadas ao medo e ansiedade frente à pandemia de COVID-19. Quatro comparações de acordo com a fase da graduação (fase pré-clínica ou clínica), nível de graduação e pós-graduação e de acordo com os sexos foram feitas. Análises independentes para as comparações entre os sexos foram realizadas para os alunos de graduação e de pós-graduação (α<5%). Resultados: Foram incluídos 408 estudantes. Na graduação, mulheres relataram sentirem-se mais ansiosas ao realizar tratamento em pacientes com suspeita de COVID-19 (54%) e sentem mais medo ao ouvir que a infecção tem causado mortes (92,4%), na pós-graduação, responderam ser mais nervosas para conversar com pacientes em ambientes fechados em comparações com homens (P<0,05). Alunos em fase pré-clínica possuem significativamente menor receio (65,5%), ansiedade (32,3%) e nervosismo (28,3%) do contágio do COVID-19 quando comparados com aqueles na fase clínica. Conclusões: Mulheres e alunos na fase clínica apresentam maior ansiedade e nervosismo. Descritores: Ansiedade; Estudantes de Odontologia; Medo; Infecções por Coronavírus.
