Reform of the bio-separation engineering curriculum under the context of "Emerging Engineering Education" / 生物工程学报

"Bio-separation engineering" is a compulsory course for undergraduate students majored in bioengineering, and an important part of the "emerging engineering education" system for bioengineering. Our teaching team follows the principle of "student development as the center, innovation thinking as the core". Guided by the concept of "learning achievement", we reconstructed the teaching contents of this course, and carried out the teaching reform aiming at solving several long-standing problems. These include, for instance, the theoretical teaching is separated from the experimental practice, and students cannot internalize the theoretical knowledge into practical ability in time. Moreover, the contents of course is out-of-date and out of line with industry demand, the teaching form and assessment methods are relatively single, and the students' professional ability and quality are not effectively cultivated. In the new curriculum system, in which the "online" and "offline" teaching are both applied, we broke the boundary between theoretical and experimental courses, and made the contents keep up with the forefront of industry development through research-based teaching. In terms of teaching methods and teaching evaluation, we made full use of modern information technology to enrich classroom teaching activities, and carried out complete, dynamic and diversified assessment for students. These teaching reform measures greatly improved the students' interest in learning this course, as well as their professionalism and research ability.

Study on epidemiological status of e-cigarette use among adolescent in Zhejiang province, China / 中华流行病学杂志

Objective: To describe the prevalence of e-cigarette use among adolescent in Zhejiang province, and to analyze its distribution of different genders and school types to provide evidence for controlling the use of e-cigarette among adolescent. Methods: A total of 7 663 students from 60 middle schools through stratified multi-stage cluster sampling methods from Zhejiang province were surveyed by using questionnaire. Indicators as tried to use e-cigarette rate, current e-cigarette using rate, and other indicators were collected. All data were weighted by age proportions of adolescent in Zhejiang. Results: The prevalence of tried to use and current using e-cigarettes among middle school students were 6.99% and 1.45%, respectively; and there were 4.19% juniors who were susceptibility to future e-cigarette use. The rate of tied to use e-cigarette, current using e-cigarette and susceptibility to future e-cigarette use were higher in boys than in girls. The rate of current using e-cigarette was 2.07% for rural and 0.48% for urban. Technical secondary school students had the highest rate of tried to use e-cigarette and susceptibility to future e-cigarette use (13.53%, 6.91%). Junior school students (2.96%) had the lowest level of susceptibility to future tobacco use. The rate of tried e-cigarette use and current e-cigarette use and susceptibility to future e-cigarette use were higher in the group of "One of students' parents was smoker" (8.63%, 2.19%, 5.23%). The highest rate of current smoking was found in the group of "Weekly allowance more than 50 Yuan" (10.02%, 2.54%, 6.29%). Compared to technical secondary school students, senior school student (OR=0.57) and junior school students (OR=0.45) were less likely to try to use e-cigarette. Students whose weekly allowance were less than 20 Yuan were less likely to try to use e-cigarette (OR=0.49). Students who were boys (OR=5.44) and one of their parents was smoker (OR=1.59) were more likely to try to use e-cigarette. Conclusions: There were middle school students with tried e-cigarette use and current e-cigarette use, especially in technical secondary schools. The prevalence of e-cigarette using among middle school students increased with age. It is important to further spread of e-cigarette knowledge widely and deeply, and reduce the susceptible population of adolescents using e-cigarettes.
