Traditional Chinese Medicine has been used for thousands of years and recently imports the western technology of dosage production. Extraction is the critical process to the production of medicine concoction which affects the quality of dosage and the effectiveness of the medical treatment. Concentration and composition of the active pharmaceutical ingredients of the herbal concoction are the two key parameters in measuring the quality of the extracts. However, the controls of extraction have faced a number of difficulties. This paper describes the methods of measuring the two key parameters by a selected Chinese herbal prescription during the extraction. Experiments were carried out for the investigation of the characteristics of the changes of the Concentration and composition of the herbal concoction. Subsequently, the problems of extraction control are outlined. The model predictive control and the adaptive control applied to the production of the herbal concoction have been discussed. The appropriate control techniques for the extraction of the active ingredients are proposed in the paper. [ABSTRACT FROM AUTHOR]

No matter how ambivalent Fu himself felt, at a time when young people believed that the tao had already shifted from Confucian texts to Western books (hsi-shu), he was very much envied by his contemporaries. In a letter from Ku Chieh-kang to Fu Ssu-nien, Ku confessed his frustration at his inability to grasp just “what is learning” (she-mo shih hsüeh-wen); his inability to read foreign books was equivalent to being unable to gain access to the new tao. Ku contemptuously announced that there was not a single chapter in Chinese books worth reading. It was also true for Fu Ssu-nien that nothing other than Western learning could be called true learning (hsüeh-wen), and he described himself as extremely hungry for “learning.” Given this scenario, when Fu and five other members of the New Tide Society went abroad to study, they were nicknamed “Five Ministers Sent Abroad” (Wu-ta-ch'en ch'u-yang), reminiscent of the five ministers of the late Ch'ing who went abroad to study the Western constitutional system. Studying in London and Berlin Fu characterized his time in London as yu-hsüeh, or general study, not study in pursuit of a degree. But when he left China in the winter of 1919, his plan was probably to get a degree from a Western country if possible. Fu first registered in the Department of Psychology at the University College of London University. He originally planned to register as an M.A. student, but on the advice of Charles E. Spearman, the department chair and a pioneer in experimental psychology, Fu decided to take courses at the undergraduate level. [ABSTRACT FROM AUTHOR]
