The purpose of this study is to explore the teaching methods and related theoretical studies of gender differences in bel canto. Focusing on four aspects: breathing, vocalization, resonance, and emotional expression, this study implements vocal music through gender-differentiated teaching methods and strategies. By carrying out a case study, the author summarizes the application and effectiveness of these teaching methods in the teaching of bel canto, and draws the following conclusions based on the research results: first, teaching methods tailored for gender differences enable students to make rapid progress in singing, breathing, vocalization, resonance, and emotional expression; their goals of learning vocal music are clearer. Second, the gender- dependent teaching methods promote the amelioration of vocal music teaching, break through the difficulties in practical teaching, and improve the teaching level and ability of instructors. Finally, this article puts forward teaching and research suggestions for vocal teachers and vocal education.

This book highlights the environmental issues, an assessment of environmental risks within the borders of Northeast Asia and neighboring territories. This book pays special attention to the transboundary factor as the main factor in international and interregional cooperation. This book develops methods of complex, thematic, interpretative mapping, geoinformation modeling, processing of remote sensing data for geographical and environmental studies, models for the analysis of spatial and temporal geographic data, and their long series. The book is planned to widely cover economic, physical-geographical and environmental studies, including the analysis of natural resources from the state of the natural environment and resource potential to its change under the influence of various factors.

Disseminated bacillus Calmette-Guérin (BCG) disease is a rare and serious adverse event following immunization (AEFI) with BCG. Here, we reported two cases of disseminated BCG disease in the same family and reviewed the literature to identify another 35 cases in China. The average age at onset was 3.7 ± 2.1 months among the 37 cases and only 21 cases (56.8%) were laboratory confirmed. Of the 37 cases, 22 were evaluated for immunodeficiency; definite immunodeficiency was observed in 16 cases (72.7%) and could not be excluded in the other six cases (27.3%). Following treatment, 20 of the 37 cases died (54.1%), one case developed sequelae (2.7%), four cases had progressive disease (10.8%), nine cases had stable disease (24.3%), and only three cases were cured (8.1%). Vaccination of infants with BCG is cost-effective and should not be stopped because of the possibility of rare disseminated BCG disease, especially in countries with high tuberculosis burdens such as China. However, infants with a family history of immunodeficiency should be vaccinated after excluding immunodeficiency-related diseases to minimize the risk of disseminated BCG disease. Furthermore, government should strengthen proactive surveillance programs to detect and treat rare AEFIs early and improve disease outcomes.

Since the outbreak of COVID-19, it became urgent to deal with the relationship between the prevention and control of the epidemic and the resumption of work and production. The purpose of this study is to observe and describe which approach seemed more important for the Chinese government and people, and how this trend evolved through time. To this end, a game model of resuming production and preventing the epidemic is constructed, using the evolutionary stable strategy (ESS). By combing China's measures on epidemic prevention and resuming production during critical periods of epidemic outbreak, it is clarified that the present stage is considered a period of equal emphasis on both epidemic prevention and resuming production. Based on the dynamic between these two strategies and further theoretical research, present policies should equally focus on both preventive and controlling measures as well as on the socioeconomic development for most countries in the world.
