In order to study the association of each item of a health examination and lifestyles with health-related quality of life (HRQoL), a cross-sectional survey by a self-administered questionnaire using the 12-Item Short Form Health Survey (SF-12, version 1) was conducted on 145 government managers that took health examinations in Tongji Hospital, Wuhan, China during 2005. The results showed that the determinations of organic functions including BMI, hemoglobin, blood platelet count, urine protein, urine WBC and lipid metabolism (LDL) were associated with HRQoL. The lifestyle items including age, sex, life satisfaction drinking alcohol and kind of alcohol drunk, drinking tea, sleep quality and adhering to bedtime, working overtime, work stress were associated with HRQoL in the multiple regression models. Sex, age and life satisfaction were the lifestyle items most closely associated with HRQoL, while LDL, hemoglobin and urine protein were the health examination items most closely associated HRQoL. This study revealed that both lifestyle and health examination items were associated with HRQoL.

In order to improve the operation ability of unmanned aerial vehicles (UAV), this paper designs a lightweight manipulator for quadrotor UAV. First, according to the requirements of the task and the load of the UAV, an aerial manipulator with lightweight and small moment of inertia is designed, and the 3D model of the manipulator is established in the Creo software. The maximum deformation and stress under different load conditions were analyzed by Ansys Workbench software, and the dynamic analysis was carried out in ADAMS software to obtain the driving moment required by each joint of the manipulator under load conditions. Finally, the dynamic model of the aerial manipulator system is established according to the Newton-Euler method, and the maximum workspace of the manipulator in the hovering state is generated by the Monte Carlo method. The research results show that the deformation and stress level are small, and the workspace meets the operation requirements, which proves that the designed manipulator has certain engineering application value.
