DSpace CRIS
DSpace-CRIS consists of a data model describing objects of interest to Research and Development and a set of tools to manage the data. Standard DSpace is used to deal with publications and data sets, whereas DSpace-CRIS involves other CRIS entities: Researcher Pages, Projects, Organization Units and Second Level Dynamic Objects (single entities specialized by a profile, such as Journal, Prize, Event etc; because any profile can define its own set of properties and nested objects)

This research used the simulate software :ADAMS and LifeMOD to establish the model and simulate the gait. The results represented the patients of FLLD have an asymmetric gait . At midstance, the FLLD patients' hip joint moment of longer limb in sagital plane is 0.2N-m/kg higher than opposite one. However, the hip joint moment of shorter limbs in frontal planes are 0.6N-m/kg higher than opposite ones. At swing phase, when knee flexion, the longer side joint have 10 higher than shorter side, and more than 3 adduction in frontal plane. Hence, comparing the gait of FLLD with normal subjects; we found the gaits of FLLD are more asymmetric and had a larger moment on the longer limb. The hip and the knee joint moment of normal subjects on sagital and frontal planes are smaller than FLLD one's. |
