As the main body of service launched by the science popularization team in rural areas, it is also a key force for enhancing scientific literacy of peasant masses and an important link connecting agriculture technology promotion and agricultural production practice. In the new era, the trend for the development of modernization of agriculture, the application of science and technology industries, and the informatization of science popularization have put forward higher requirements on the comprehensive capabilities of rural science popularization personnel. This paper aims to fully understand the status of the construction of the current ranks of science popularization talents in rural areas, find out outstanding problems and their causes faced by it and better promote their own construction and sustainable development of science popularization ranks. Through methods of field observation, in-depth interview and comparative analysis, this paper carried out in-depth field work towards the rural science popularization in “four provinces and twelve cities” in China. The results of the survey show that: the construction of rural science popularization team is not enough, the content and form of science popularization find it difficult to adapt to the requirements of the new era, the echelon of science popularization talent ranks is under the pressure of “fault”, the management attribution of science popularization team is not clear, and the rural science popularization organization system is not perfect. In view of the afore-mentioned problems, the paper finally puts forward some suggestions, such as strengthening policy support for construction of popular science popularization in rural areas, transforming rural science popularization service forms, improving incentives for rural science popularization team, building a diversified management system of science popularization personnel, and perfecting science popularization system and grass-roots science and technology associations.

An initial goal for science popularization work of China is to raise scientific literacy of the population, and youth is one of the most important targeted groups to realize the afore-mentioned goal. As a mass informal activity, the youth university science camp is held annually in China. Based on the result of a large-scale (N=10393) investigation, this research proved a positive effect of this camp on raising campers' scientific literacy and discovered its unique character featuring cutting-edge and multi-disciplines. Effects on different groups of campers were compared as well. Some specific suggestions were given for a further improvement of the camp in the future.

By analyzing 6870 samples, online and offline questionnaires were utilized to investigate the access to popular science knowledge by different audiences in the Yangtze River Delta region. The questionnaire covered 5 categories of audience——the juveniles, peasants, urban workers, community residents, leading cadres or officials, and public civil servants. Some suggestions were put forward in the paper, to improve the scientific transmission mode for innovating the method of science communication from the public's perspective, to improve the efficiency of public access to the popular science knowledge, and to improve the accuracy and coverage of popular science dissemination through the precisely and comprehensively-targeted means of science popularization, the abovementioned measures contributed to providing references for the government to improve the popular science work.

Promoting the combination of scientific research and science popularization, encouraging and guiding scientists to participate in science popularization, especially in popular science writing, is one of the initiatives in the field of science communication in China. Based on questionnaire survey and panel interviews, this research tries to analyze the current situation of scientists' engagement in popular science writing, their problems and requirements. According to the investigation, Chinese scientists widely believe that it is their responsibilities to participate in popular science writing and they show strong willingness to that. However, they don't actively engage in popular science writing accordingly, and even if involved in it, the form is quite traditional. Interest and social responsibility act as the main motivation for them to participate in popular science writing. The lack of time and energy, imperfect assessment and incentive mechanism are the main obstacles. And on the demand side, the scientists expect a better policy environment and incentives, as well as the corresponding training and services. Based on the aforementioned research, the paper puts forward relevant countermeasures and suggestions on inspiring scientists to participate in popular science writing.

Chinese ancient literary works contain a large number of scientific and technological factors, including the observation and recording of astronomy and geography at that time, the understanding and thinking of natural changes, the generalization and description of technological processes, and the imagination and prediction of the mysterious future. Through the study of ancient myths and legends, folk ballads, novels and operas of these four types of popular literary works, which contains the analysis of the specific technological content and function of science education, it helps to enhance the interest and effectiveness in the popularization of science and technology, and to gain a new understanding of the value of the ancient Chinese literary works.

During the period of the Republic of China, the country suffered a difficult time, and the people were lacking knowledge about health, therefore, a great number of periodicals came to the forefront to assume responsibility for disseminating knowledge about infectious diseases to the public in a wider scope, such as the knowledge of pathogenesis, infectionroute, symptom, therapies, and the prevention methods. The popularization activities contributed to enhancing public's awareness in the prevention, promoting the progress in national public health, and bringing hope and confidence to the infectious.

Featured with immersive experience, Dome theater is a multi-purposefacility for science education and has been becoming the main type theaters in the science museums in China. Through summarizing the origin and development of the dome theater, it is obvious that digital dome theater embodies the dual function of films releasing and science education on astronomy. The data of dome theaters in science museums between China and the United States are comparatively studied in the paper, including quantities, sizes, shows, educational activities and amount of audiences. The findings in the research reveal that albeit the scale of big dome theaters in China is largely the same as that of the U.S., the amount of audiences and popularity are less and lower. The main reasons contain three aspects. Firstly, the function and orientation of Chinese dome theater is oversimplified which results in lacking educational activities. Secondly, the production of films and shows is insufficient and the price of rent is high. Thirdly, the formats of dome system are not standardized which brings about the difficulty in film releasing on different dome theaters. In order to have the current situation changed, it calls for three aspects to be promoted accordingly. The advice to dome manager is that astronomy education and the real-time show is the key point for dome activity and film production. The suggestion to the related department is to formulate standardized guidance.

With a long history in Scientific communication, “Science and Society” is an important part of the British government's technological innovation policy. The government views Science and Society as a necessary condition for British and global success. The background, policy making and development process, specific content and measures, the latest progress and the new development of the Science and Society Programme of UK in the past 10 years are systematically analyzed. The study finds that the British government plays a leading and “catalyst” role in the development of the programme. In order to maintain the policy's effectiveness, efforts shall be made to make the policy content be embodied and targeted, to adequately engage experts in wider organizations and relevant fields during the entire process of policy formulation, implementation and evaluation, to interact with the public, to maintain coordination among relevant social organizations, to follow up on the implementation of policies, to conduct timely experience summary, and to carry out policy revision.
