The zuozhen wood, a unique and precious Cudrania tricuspidataspecies native to Nantong, is an ecologically and economically versatile species. Historically, it has been used for furniture making, brewing wine, medicinal purposes, and more, playing a key role in the local ecological environment and culture of Nantong. This paper explores the potential for the ecological and social benefits of the Zuozhen and its industry under the new era context, as well as some current issues in its development, and offers suggestions for further development.

With the rapid development of computer networks, digitization has become a new symbol of today's social and economic development. The "digitalization" of mining exploration and mining results data is one of the essential contents of current mining work. This article will use the large-scale mine engineering software Surpac Vision to construct a digital ore deposit model of the Manjiazhai section and realize the three-dimensional visualization of the ore body. It intuitively reflects the spatial continuity, thickness variation, resource reserves, and grade spatial distribution of ore bodies. On this basis, a block model is established. In calculating the valuation of the unit block, a computer is used to dynamically analyze the changes of ore bodies with different boundary grades and the changes of ore bodies' shape and average grade under single elements and combined elements. Comparative analysis shows that the ore bodies with comprehensive grade delimits have good continuity under the same boundary grade. The average grade and metal content are higher than the single-grade circled ore body, indicating that improving the comprehensive utilization of resources will be conducive to improving the service life of the mine and increasing the overall economic benefits of the mine, suggesting that it is adequate to apply the digital deposit model to the comprehensive utilization of mineral resources, which will provide data support for the green and sustainable development of mining enterprises.

With continuous economic development, energy and environmental issues have become increasingly prominent. Hydrogen energy, as a novel energy source, boasts advantages such as high energy density and zero-pollution products. The development and utilization of hydrogen are crucial measures to address energy shortages and environmental pollution. This paper introduces the current status of the four major hydrogen production technologies worldwide and the research progress in dye sensitization technology. Among these, solar hydrogen production technology, when combined with dye sensitization technology, has led to the development of dye-sensitized photocatalytic systems, garnering global attention. We summarize and analyze the research status of dye-sensitized photocatalytic systems by domestic and international scholars and propose suggestions for their future development.

In the development of side-impact safety performance in automobiles, the injury conditions of far-side occupants have gradually been incorporated into the evaluation system of automotive safety in China. This study, based on three side-impact conditions in the Chinese automotive safety assessment system, employs the finite element method to analyze the injury and motion characteristics of far-side occupants under various impact scenarios. The results indicate that in the C-NCAP 75° POLE condition, certain impact areas of the far-side dummy sustain more severe injuries. These findings provide data references for the development of safety performance measures aimed at protecting far-side occupants.
