The Research on the Paths of Popular Science Education about Myopia Prevention and Control among College Students in the Context of Shifting the Focus Forward

Currently, the number of myopic people in China has reached as high as 600 million, and it shows a trend of “early onset, high incidence, and a high degree of severity”. The issue of myopia among children and adolescents has attracted widespread attention from all sectors of society. Comprehensive myopia prevention and control efforts have been launched nationwide. Popular science education, vision screening, and improving visual environments are effective measures for preventing myopia. However, among the target audience for comprehensive myopia prevention and control, the preschool children group has been neglected, and the work of myopia prevention and control for this group has been significantly weakened and marginalized. Due to insufficient awareness of prevention and control, the hyperopia reserve in the preschool children group is being continuously depleted, leading to the early onset of myopia. In light of this situation, the focus of myopia prevention and control needs to shift forward, and it is worth exploring and pondering how college students with a background in optometry can develop entertaining and engaging popular science education materials and methods.

Research on the Planning of Medicinal Botanical Gardens Based on the Theme of Science Popularization Education

The functions of medicinal botanical gardens are introduced firstly,and then the application status and planning principles of medicinal botanical gardens based on the theme of science popularization education are analyzed.Moreover,a typical application case is analyzed and summarized.Constructing a scientific medicinal botanical garden is conducive to increasing people's understanding of medicinal plants,and also meets the requirements of current national policies,thereby generating greater economic and social benefits.

Reconstruction and Regeneration of Mountain Landscapes: A Case Study of Science Popularization and Education Hall of Jiangxi Wuyi Mountain Nature Reserve

Mountain landscape is a significant landscape type among all natural landscape resources, design of constructions in mountain landscapes should take multiple factors into consideration. Taking Science Popularization and Education Hall of Jiangxi Wuyi Mountain Nature Reserve for example, this paper explored the architectural design in mountain landscapes from the perspectives of spatial form, facade design, color materials and design experience, in order to achieve the integration of landscape constructions and natural environment.

Nuclear Safety Education for Non-nuclear Engineering Students

The new situations were analyzed for nuclear industry development and security. Besides nuclear wars and terrorism, reactor runaway and un-ruled radioactive source are the main nuclear accidents in peacetime. With the active development of the nuclear industry in China, the existing nuclear education system is becoming deficient or defective. Human factors play an important role in nuclear accident prevention and emergency response in the nuclear engineering system, non-nuclear professional staff are often the subject of personnel in most nuclear projects. In order to ensure the sustainable and efficient accord development of nuclear industry, general nuclear education is necessary for correlative non-nuclear professionals, such as technologies, management, safety, culture and ethic. The nuclear safety education should be included into the national education system.

Dynamics and near-optimal control in a stochastic rumor propagation model incorporating media coverage and Lévy noise

The appearance of rumors intensifies people’s panic and affects social stability. How to control the spread of rumors has become an important issue which is worth studying. In order to more accurately reflect the actual situation in the real world, a stochastic model incorporating media coverage and Lévy noise is proposed to describe the dynamic process of rumor propagation. By introducing two control strategies of popular science education and media coverage in an emergency event, an near-optimal control problem that minimizes the influence and control cost of rumor propagation is proposed.Sufficient conditions for near-optimal control of the model are established by using a Hamiltonian function. Then the necessary conditions for near-optimal control are obtained by using the Pontryagin maximum principle. Finally, the effect of popular science education, media coverage and Lévy noise on rumor propagation process control is verified by numerical simulation.

Enlightenment from the Construction of American Botanic Gardens:A Case Study of The Morton Arboretum

Starting from reviewing the current development of botanic gardens in China,the shortcomings of current research on botanical gardens in China are summarized:the research and construction concepts of the botanical gardens lack professional characteristics;the education and science popularization system is extensive;and the investment and construction model and operation and management method are relatively rigid.Through combing the development history of The Morton Arboretum and introducing its construction features,such as the long-term garden-establishing idea with a high starting point,continuously building and improving for a long time to actively adapt to changes in social needs,a refi ned education and science popularization system for various groups,and a strong self-hematopoietic function,the successful construction experience of The Morton Arboretum is elaborated and the enlightenment from The Morton Arboretum to the construction of botanic gardens China are put forward,so as to provide a reference for the construction and development of botanic gardens in China in the new period.

Investigation of Amoxicillin Use in Fever Clinic Patients:Standardized Application of Antibiotics is Still Challenging

Amoxicillin is widely used by the Chinese population and available in pharmacies without prescription.We performed a retrospective study on patients with fever who took amoxicillin before going to the fever clinic of the Second Affiliated Hospital of Nanchang University from March 1,2020 to March 31,2021.Among the total of 9093 patients attending the fever clinic,446 patients had a history of taking amoxicillin,from which 100 cases were randomly selected to evaluate the therapeutic effects of non-prescribed amoxicillin by changes in clinical symptoms,counts of white blood cells,neutrophils,and lymphocytes,and levels of C-reactive protein(CRP).The control group consisted of 100 randomly selected patients for who it was verified that they did not take antibiotics before attending the fever clinic.Our study showed that there were no significant differences between the group of patients taking amoxicillin and the control group in terms of symptom improvement,white blood cell,neutrophil or lymphocyte counts,or the levels of CRP.Therefore,our study indicated that although non-prescribed amoxicillin is widely used among patients with fever,it does not provide significant beneficial therapeutic effects.There is still a long way to go to standardize the application of antibiotics and popularize knowledge on proper antibiotics use among the population.
