All steps of the proof rely on common informal set-theoretic reasoning, but they take into account the prohibitions that were introduced into axiomatic set theories in order to overcome the difficulties encountered by the naive Cantor set theory. Therefore, in fact, the article is about proving the inconsistency of existing axiomatic set theories, in particular, the ZFC theory.展开更多

Urinary iodine, salt iodine, and thyroid volume(TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the2017 national survey. Multi-factor regression analysis was used to find correlations between variables.Results Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other places.The percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively(r = 0.999 and-0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL(r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children’s iodine nutrition status.Conclusion Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.展开更多

Research data are collected by using questionnaire survey method, and statistical analysis of data is conducted using SPSS 21.0. Research has found that leisure involvement has a significant positive impact on authenticity experience, place attachment, and willingness to revisit;authenticity experience has a significant positive impact on place attachment and willingness to revisit;place attachment has a significant positive impact on willingness to revisit. Therefore, shared accommodation owners need to strengthen the editing and publishing of leisure strategies on we media to enhance customers sense of leisure involvement;pay attention to enhancing the local authentic cultural experience of tenants, in order to increase their sense of attachment to the place and thereby enhance their willingness to stay.展开更多
