Just-in-time ( JIT) Educational Strategy has been applied successfully to share scientific knowledge about disasters in several countries. This strategy was introduced to China in 2008 with the hopes to quickly disseminate accurate scientific data to the population, and it was applied during the Sichuan Earthquake and Influenza A (H1N1) outbreak. Implementation of this strategy likely educated between 10,000 and 20,000,000 people. The efforts demonstrated that an effective JIT strategy impacted millions of people in China after a disaster occurs as a disaster mitigation education method. This paper describes the Chinese JIT approach, and discusses methodologies for implementing JIT lectures in the context of China's medical and public health system.

In the context of rapid urbanization, the proliferation of high-density residential zones and intricate infrastructure networks markedly amplifies a city's susceptibility to natural calamities, notably seismic events. Thus, a precise evaluation of a city's emergency capability for seismic events is imperative. This research proposes a novel and all-encompassing evaluation framework for indicators, grounded in crisis management theory, covering the entire spectrum of disaster mitigation, preparedness, response, and recovery.

Blasting excavation is widely used in mining, tunneling and construction industries, but it leads to produce ground vibration which can seriously damage the urban communities. The peak particle velocity (PPV) is one of main indicators for determining the extent of ground vibration. Owing to the complexity of blasting process, there is controversy over which parameters will be considered as the inputs for empirical equations and machine learning (ML) algorithms.

Accurately analyzing the type of land use and change characteristics of disaster damage in landslide areas is of great significance to scientifically promote the optimization of regional land use pattern and disaster prevention and mitigation. We analyzed the characteristic parameters of landslides as well as the characteristics and driving factors of land use change from 1985 to 2020 in Tongwei County, Gansu Province, using ALOS DEM data and 1985-2020 land use data, GIS spatial analysis, land-use dynamic attitude, transfer matrix, and Geodetector. The results showed that a total of 1012 landslide samples were identified, characterized by medium elevation, gentle gradient, low elevation difference, short length, and small size.

To clarify the response mechanism of exogenous paclobutrazol on drought resistance in seedlings, we investigated the effects of spraying different concentrations of paclobutrazol (25, 50, 100 mg·L) on the photosynthetic and antioxidant systems of 2-year-old seedlings under drought stress using natural drought method. The results showed that drought stress significantly reduced the photosynthesis and broke the dynamic balance of antioxidant system in seedlings. Spraying with different concentrations of paclobutrazol effectively alleviated the negative impacts of drought stress, and enhanced the defense capability of photosynthetic and antioxidant systems, with the 100 mg·L paclobutrazol treatment being the most effective.

Background: Rice is the main food crop for much of the population in China. Therefore, selecting and breeding new disease resistance and drought tolerance in rice is essential to ensure national food security. The utilization of heterosis has significantly enhanced rice productivity, yet many of the molecular mechanisms underlying this phenomenon remain largely unexplored.
