How do Psychological Factors Influence Disaster Preparedness? Evidence from Disaster-Stricken Mountainous Areas of China.

Objectives: Disaster preparedness plays a vital role in mitigating risks and strengthening resilience of local communities in rural areas. This study examines the linkage between psychological factors and 4 kinds of disaster preparedness intentions and explores the challenges in translating intentions into actions.

Methods: This study utilized survey data from 325 households in Chongqing, China, that are threatened by geological disasters.

Non-contact detection method of pregnant sows backfat thickness based on two-dimensional images.

Since sow backfat thickness (BFT) is highly correlated with its service life and reproductive effectiveness, dynamic monitoring of BFT is a critical component of large-scale sow farm productivity. Existing contact measures of sow BFT have their problems including, high measurement intensity and sows' stress reaction, low biological safety, and difficulty in meeting the requirements for multiple measurements. This article presents a two-dimensional (2D) image-based approach for determining the BFT of pregnant sows when combined with the backfat growth rate (BGR).
