The recent succession of food crisis and the rise of food scare have endangered the relationship of trust between the consumers and the primary food production parties: raisers, growers, industrial partners, distributors, public institutions, as well as the secondary food production parties: consumer groups and medias. Facing a potentially risky product, the consumer in his collect of risk diminishing information, should be able to trust something or someone. But in order to trust a risk diminishing element, he must first trust its emitter. In order to enhance consumer perception towards Lebanese food safety, we began a survey on a sample of a population randomly selected. The study found significant difference among education levels concerning attitude towards food safety and knowledge. No significant effect of demographic profile and sex on food handling practices was found. These findings increase concerns about consumer safety knowledge and practices. It is advised that a national survey should be conducted, followed by a properly designed food safety public health campaign, to enhance household food safety awareness. 展开更多

While playing an increasing role in the field of air-space integrated networks,terminal entities are exposed to more serious security risks than ordinary terminal entities on the ground,including but not limited to astronomical risks(e.g.,solar activity),link disruptions,and malicious attacks.In the integrated air-space-space network,after the terminal entity is loaded into the rocket for launch,real-time monitoring measures are implemented on the ground site for all links to the intended orbit.On top of the real-time monitoring measures,the need for a comprehensive evaluation of the air-space integration network is growing.In this paper,we further classify the security requirements and evaluation benchmarks of the terminal entities of the air-space integration network around the security evaluation requirements of the air-space integration network.On this basis,the relevant concept of trust value is introduced to assess the security status of terminal entities of air-space-sky integrated networks,and on this basis,a security assessment system of air-space-sky integrated network terminals is proposed.The exploration and development of field applications are initially realized. 展开更多
