Nowadays, it seems completely natural for us to shake hands when we meet someone or say goodbye to others. However, why do we do so?In the olden days, the hand was a symbol of power and strength. Then, there was no machinery or weapon. The hand was very important. It was used to catch or kill animals, fight enemies, make tools and weapons. So, when a person extended his hand to someone, it showed that he was not armed. This could mean goodwill or friendship. 相似文献

On a hot summer morning in 1989 I finished packing my things in my flat in Dublin. Two suitcases were not enough to hold them all so I had to use plastic supermarket bags for the remainder. My friend Tom arrived in his car to take me to the airport. After coffee at the airport we shook hands and said goodbye and it was only then that I noticed my hand was shaking. My voice was also shaking and my breath was coming out in uneven waves. Tom was my good friend from schooldays and in saying goodbye to him I was saying goodbye to so many good memories, saying goodbye to my country. 相似文献

A novel approach to realistic collision-free animation of the upper limb was proposed.According to the obstacle-avoidance strategy of human hand,the movement trajectory was computed by manipulability model and minimum-jerk based interpolation.In each key frame,an improved in～verse kinematics method was adopted to obtain a believable posture of the upper limb.By comparing with the real movement data obtained from the motion capture device,the resultant animation was testified to be natural.This method can be performed in interactive time,and therefore is applicable in animation edit and control of virtual humans. 相似文献

Objective: To identify the mutations of iduronate-2-sulfatase (IDS) gene, to reveal its mutation features, and to establish a basis for genetic counseling and prenatal gene diagnosis of Hunter syndrome. Methods: Urine glycosaminoglycans (GAGs) assay, PCR and DNA sequencing were performed to detect mutation of IDS gene of the patient and his parents. Results: The result showed that the patient was: DS( ), HS( ), KS(-), CS(-), and that both of his parents were negative. A frame-shift deletion mutation (1062 del 16) was identified in exon 7 of the patient's IDS gene. His parents' genotypes were normal. Conclusion:The patient's mutation was not inherited by his parents but a novel one. The mutation probably altered the primary structure and tertiary structure of IDS enzyme protein remarkably and lowered the activity of IDS enzyme greatly. Therefore it is supposed to be the direct cause of the disorder. 相似文献
