Exercise dosage is proven to be an important factor in the physical treatment. Robot assistive approach can improve the rehabilitation quality and evaluate patient’s recovery quantitatively. This paper presents kinematic structure, assistive control system, and integrated F/T sensor for an upper limb rehabilitation robot. By using the human arm dynamic, there are three rehabilitation modes presented in this paper: active mode, assistive mode, and passive mode. In assistive mode, we have two strategies to implement it. One is to amplify interactive torque, and the other is to apply assist-as-needed concept. The goal of this mode is to assist patients to finish motion tasks. The rehabilitation robot under investigation has 7 degree of freedom (DOF) actuated by DC motors, which are programmed to drive the robot arm in the 3D space. To validate our control design, some realistic experiments are conducted and its satisfactory performance is demonstrated. This work is approved clinical testing by the Department of Health, Executive Yuan, R.O.C. So far, we are demonstrating the effect of our controller.

A 58-year-old male patient presented with a recurrent true malignant mixed tumor of the parotid gland. Patchy pulmonary opacities were identified with a chest radiograph. Subsequently, a CT scan of the chest showed pulmonary parenchymal consolidation with amorphous calcifications. This abnormality was confirmed to be the result of a metastatic true malignant mixed tumor by using CT-guided biopsy. The current case demonstrated an extremely rare example of atypical pulmonary metastases from a true malignant mixed tumor of the parotid gland showing an air-space pattern and calcification.

The purpose of this study is to investigate the effect of green tea (Camellia sinensis) powders on fermentation and survival of probiotic yogurt. Green tea powders were added to milk, sterilized, fermented with Lactobacillus reuteri LYC184 and stored at 4°C for 14 days. The quality parameters of green tea powder yogurt (TP) included bacterial number, pH, titratable acidity, color and physicochemical properties were analyzed. Results showed that the adhesiveness and pH value decrease as the storage time increases; the value of titratable acidity, viscosity and hardness are proportional to the storage time. The phenolic compounds in green tea yogurts were analyzed by HPLC. The novel yogurts showed significantly higher probiotic cell viabilities during storage at 4°C. In conclusion, adding the green tea powders to Lactobacillus reuteri LYC184 fermented yogurt is an excellent functional food that has great potential for the beneficial properties of human health.
