For this purpose, a 3D human head finite element model （HBM-head） was developed based on head-brain anatomy. The HBM head model was validated with two experimental tests. Then the head finite element（FE） model and a multi-body system （MBS） model were used to carry out reconstructions of real world vehicle-pedestrian accidents and brain injuries. The MBS models were used for calculating the head impact conditions in vehicle impacts. The HBM-head model was used for calculating the injury related physical parameters, such as intracranial pressure, stress, and strain. The calculated intracranial pressure and strain distribution were correlated with the injury outcomes observed from accidents. It is shown that this model can predict the intracranial biomechanical response and calculate the injury related physical parameters. The head FE model has good biofidelity and will be a valuable tool for the study of injury mechanisms and the tolerance level of the brain.展开更多

With the unprecedented growth of international tourism in the past fifty years, during which hospitality has reach the status of a mature industry, the focus has moved from consumer protection (generally guaranteed by national regulations and legislation) to consumer information. Today, standardization and competitive marketing of hotel services to foreign customers and tourist professionals have emerged as driving forces for instituting a local or national hotel classification system.展开更多

It is also a process to await the Fourth World Conference on Women to be held in Beijing in 1995, a process to further mobilize women from various countries to gain equality between the sexes and to take a part in social development. The second international seminar on women’s studies was held from November 23 to 26, 1993, at Beijing University in preparation for this day. Some 100 women researchers from Australia, Bangladesh’, Canada, the United States, England, Malaysia and Japan, as well as Hong Kong and China participated in the event. It was one of the most lively and active seminars held during this process. To take prompt action in development was a common nderstanding of the participants.展开更多
