Changes of users' query volume in online fight ticketing systems indicate the changes of requirements in civil aviation markets. By analyzing the big data of users' online query behaviors, we can timely and accurately discover abnormal civil aviation requirements. This ability is very conducive for airlines and agencies for taking immediate and effective marketing actions. In this paper, we propose a novel method to discover abnormal civil aviation requirements based on time-series curves of users' query volumes. In addition, we utilize the domestic airline route network to optimize the anomaly detection results from the perspective of a global network rather than that of a single airline. We conduct experiments on real-world users' query datasets collected from an online ticketing site. The experimental results demonstrate that the proposed method can effectively discover abnormal civil aviation requirements from users' online query logs.

Pilots' stimulus &operation is important for aircraft flight safety. For aircraft system safety design, safety assessment should consider it. But till now in the aircraft design process, there has little consideration about it. In this present paper, pilots' stimulus & operation is considered from view of psycho-physics, and then a new idea of FHA (Function Hazard Analysis) considering pilots' stimulus & operation had shown. And for verification of system safety by SSA (starting from FHA, then FMEA & FTA) is developed into a new road-map.

To understand the present situation of the elderly medical care in the northern third district of Qigihar (Jian Hua District, long Sha district and Tie feng District), analyze the influencing factors and analyze the old-age mode of the combination of home medical care according to the actual demand, and provide the basis for the development of home medical care and the old-age mode in Qigihar.
