Previous many researches have confirmed that human adapt the position of digits to object attribute, for example, the shape of objects and center of mass (COM). Eight healthy subjects took part in the experiment (four females and four males, aged between 20 and 25 years), and they were righthanded. The goal of this research was to confirm the influence of object's vision and weight on digit placement...
The thumb and index finger are important digits to performed dexterous and complex manipulation of objects. However, the local muscle fatigue will induce the capacity of force production and impair the precision motor control of the thumb and index finger. This study focused on the exercise-induced local muscle fatigue influencing the COP (center of pressure) area, the SD and the PA (projection angle)...
The inter-digit coordination during precision grip was assessed using a recurrence-based phase synchronization (PS) analysis in this study. The PS across the normal forces of the thumb and index finger with respect to the contact surface serve as a critical dynamical strategy underlying precision grip. When both the thumb and index finger had reduced tactile sensitivity, the PS of Fz increased compared...
This study investigated the effect of tactile sensation on the fingertip center of pressure (COP) signals when the thumb and index finger interact with an object for stable precision grip. Thirty healthy subjects participated in the experiment. The tactile sensitivity was modulated by wrapping up the distal pads of the thumb and index finger with transparent polyethylene films. Subjects were instructed...
This study examined the fingertip force variability on the left and right hand during low-level sustained precision pinch with the thumb and index finger. Ten healthy, right-handed subjects were required to pinch a device with a stable force output at 5 N for 1 min. The pinch force was recorded for the right and left hand, separately. Visual feedback was provided for the first 30 s and removed for...
The monitoring about the changes of land use and cover and NPP in mining area is one of hot spots in the field of resources and environment. Combining with ground field survey data, the remote sensing image in different periods in mining area and the geographic information technology are used to study the changes of Land Use and Cover and NPP. The results show that the degree of the change of land...
Service trade increasingly becomes an important criterion of a country's overall international competitiveness assessment. The purpose of this thesis was to analyze China's current service trade competitiveness and prompt strategies for China's service trade development. This thesis empirically studied China's service trade of TC and the RCA index, and comparatively analyzed service trade between...
In order to further promote quality education and meet the needs of social development for talents, China's education field started a new wave after the main education, researching education and so on, it was a bilingual teaching. This thesis started from the theories of bilingual teaching models, analyzed the several models of bilingual teaching, then it compared bilingual teaching models of the...
