51. Examining Scientific Literacy through New Media

Author

Gu, Xiaoqing, Wang, Chunli, and Lin, Lin

Abstract

This study aims to evaluate the impact of new media on scientific literacy. Content analysis with a coding scheme was performed on 42 filtered websites and 20 microblogs to analyze the role of new media in disseminating scientific knowledge. The results showed that the quality of science-oriented websites was higher than that of microblogs. Although both types of new media include valid and accurate information, concerns have been expressed regarding the lack of in-depth analysis of scientific knowledge. In addition, a questionnaire was administered to 1,870 sampled college students to determine their scientific literacy levels. According to the results, the use of science-oriented microblogs does not produce a statistical difference, whereas students who use science-oriented websites have higher scientific literacy level than the non-users. Furthermore, students' identification ability for scientific information from new media is significantly correlated with their scientific literacy. Students' education, major, and identification ability contributed to their scientific literacy. Suggestions about how to improve the quality of science-oriented new media and how to develop students' scientific literacy through new media have been discussed.

Abstract

The purpose of investigating the carbohydrate exchange method in combination with aerobic exercise for obese college students is to help college students have better bodies to cope with their academic life. This paper introduces the qualitative and quantitative analysis technique based on near-infrared spectroscopy, starting from the analysis of the carbohydrate exchange method, and explains the physical, mathematical, and chemical information bases, respectively. A NIR detection model is constructed using the NIR spectroscopy detection method, and the main evaluation indexes of the model are given. Three experimental groups, namely, carbohydrate exchange method, aerobic exercise, and carbohydrate exchange method combined with aerobic exercise were set up to investigate the physical health interventions for obese college students. In the single test, the FPG, BUN, TC, and HbA1c values of the subjects in the carbohydrate exchange experiment group were reduced by 18.61%, 17.33%, 11.09%, and 18.16%, respectively. The FPG, BUN, TC, and HbA1c values were reduced by 23.42%, 18.84%, 11.62%, and 13.48%, respectively, in subjects in the aerobic exercise experimental group. From the carbohydrate exchange method combined with the aerobic exercise experimental group, the subjects’ FPG, BUN, TC, and HbA1c values were reduced by 28.38%, 22.24%, 11.27%, and 27.4%, respectively, which was a better level of intervention than the single experimental group. Thus, the carbohydrate exchange method combined with aerobic exercise can be an effective intervention for the physical health of obese college students.

89. Connected door spaces and topological solutions of equations

Author

Abstract

The connected door space is an enigmatic topological space in which every proper nonempty subset is either open or closed, but not both. This paper provides an elementary proof of the classification theorem of connected door spaces. More importantly, we show that connected door topologies can be viewed as solutions of the valuation $f(A)+f(B)=f(A\cup B)+f(A\cap B)$ and the equation $f(A)+f(B)=f(A\cup B)$, respectively. In addition, some special solutions, which can be regarded as a union of connected door spaces, are provided., Comment: A small gap in the proof of Theorem 3 in the published version has been corrected
