Abstract：在经历了长期高速增长以及国际经济形势转变以后，中国经济面临着较为严重的系统性风险。中国政府对此予以高度重视，提出既防"黑天鹅"，也防"灰犀牛"。文章对中国经济面临的"灰犀牛"和"黑天鹅"进行了分析，认为当前最大的"灰犀牛"是不断膨胀的整体债务和高企的杠杆率，当前的"黑天鹅"是难以预测的外部猛烈冲击。导致"灰犀牛"奔跑的两大潜在因素是经济下滑和利率攀升，而"黑天鹅"通过贸易渠道引爆"灰犀牛"是当前的最大风险。

Abstract： After the 20th National Congress of the Communist Party of China, China has entered a new era of development. Simultaneously, the rapid advancement and extensive application of artificial intelligent technologies have activated a new wave of economic potential and brought about new security challenges to socioeconomic development. This study firstly analyzes the characteristics of the new development pattern in global contexts, and examines the risks and challenges of digital intelligence security (DIS) under the new pattern, encompassing technological security and personal security at the micro-level, as well as economic security, social security, and cultural security at the macro-level. Based on this analysis, the study proposes the basic methodology for constructing a new paradigm for DIS, which includes enhancing the security of intelligent technology itself, ensuring DIS through intelligent technologies, and establishing relevant legislation, regulations, and policies. Finally, the study explores the dialectical and synergistic relationship between DIS and the new development pattern, providing guidance for ensuring the healthy and sustainable development of social and economic development in the new era.

Abstract： As digital technologies continue to be integrated into the whole process of economic and social development, promoting the modernization of digital technology-enabled national governance systems and capabilities has become an important way to seize the strategic initiative in the future world competitive landscape, and has attracted the attention of countries around the world. The rapid development of digital technologies such as big data collection, storage, processing, and analysis is constantly optimizing the organizational system structure of national governance, upgrading and perfecting the quality and methods of national governance personnel, and accelerating the process of making national governance efficient, scientific, intelligent and refined. At present, the national governance of China has made remarkable achievements but still faces many problems and challenges. The development of digital technologies for national governance needs scene expansion and talent supply, and the negative effects of digital technologies put new requirements on national governance. Based on the current development needs of the modernization of national governance supported by digital technology, this study puts forward suggestions to promote the modernization of national governance system and governance capacity endowed by digital technology, and quicken the pace to reach the overall goal of realizing the modernization of national governance.

Abstract： Objective To investigate the relationship between polymorphisms of surfactant protein D (rs3088308 and rs721917) and the susceptibility to silicosis. Methods This case-control study included 125 silicosis patients and 125 individuals exposed to industrial dust but without silicosis (control group), who were strictly matched with the case group for age, gender, work type and cumulative length of dust exposure. The rs3088308 and rs721917 polymorphisms of surfactant protein-D were detected in all the participants using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The frequencies of T/T, T/A and A/A genotypes of surfactant protein-D rs3088308 locus were 22.2%, 71.2% and 5.6% in the case group, significantly different from the frequencies of 17.6%, 58.4% and 24.0% in the control group, respectively (P< 0.05). The frequencies of C/C, C/T and T/T genotypes of rs721917 locus were 17.6%, 56.8% and 25.6% in the case group, similar to the frequencies of 15.2% , 60.0% and 24.8% in the control group, respectively (P>0.05). Conclusion Surfactant protein-D rs3088308 polymorphism is significantly associated with silicosis, and the T allele may be a risk factor for silicosis in individuals exposed to industrial dust.

Abstract： Data element governance is a key factor to promote the modernization of national governance in the digital era. By strengthening the deep integration of data factors and national governance, a new model of data-driven national governance can be formed, and the national governance can be made more scientific, refined, intelligent, and efficient. The US and European countries have continuously strengthened the top-level system design, technological innovation application, collaborative governance mechanism, and global governance cooperation of data element governance, which has effectively improved the level of data element governance and provided experience for China. Nevertheless, due to the virtuality of data elements, more subjects involved, greater risk of leakage, and higher requirements of technical support level, the current data element governance is still faced with challenges such as imperfect collaborative governance mechanism, incomplete ethical governance mechanism, weak talent and technology foundation, etc. It is thus challenging to give full play to the role of data factors to meet the needs of the modernization of national governance. In the new era, it is urgent to establish and improve a data element governance system suitable for current major needs and application scenarios of national governance, by establishing a governance concept that takes into account the development of efficiency, fairness, and security in all directions, building a governance model featuring the collaboration and co-governance of multiple subjects of the government, the market, and society, strengthening a governance idea driven by the synergy of science, technology, and institutions, and improving the basic guarantee of talents, infrastructure, and public services, to promote the governance level of data factors and provide strong support for the modernization of national governance system and capacity.

Abstract： Food security is an important guarantee of national security. The northeast black soil region is an important commodity grain production base in China, which plays a fundamental role in ensuring national food security. However, the highly intensive, unreasonable or excessive use of cultivated land in this region has caused serious black soil degradation. Therefore, how to make the Black Soil Granary to provide efficient and sustainable guarantee for national food security is a scientific problem requiring urgent solutions. This paper systematically illuminates the agricultural development of high-productivity black soils since the reform and opening-up. On this basis, the paper systematically summarizes the problems facing the sustainable development of grain production in the black soil region. Furthermore, to meet the requirements of the central government for agricultural production in Northeast China, it puts forward the corresponding countermeasures to coordinate food security and ecological security and to enhance the sustainable development of grain production, intending to provide reference for the sustainable agricultural development in the northeast black soil region, and offer scientific guidance for the strategic planning of national food industry strategy, agricultural policy making, and strengthening of national food security.
