To explore advantages of Chinese medicine (CM) by analyzing differences in the origin of philosophy for human health between CM and Western medicine (WM). Methodologically, a distinctive feature of CM is its systems theory, which is also the difference between CM and WM. Since the birth of CM, it has taken the human body as a whole from the key concepts of "qi, blood, yin-yang, viscera (Zang-Fu), and meridian and channel", rather than a single cell or a particular organ. WM evolves from the Western philosophic way of thinking and merely uses natural sciences as the foundation. The development of WM is based on human structures, or anatomy, and therefore, research of WM is also based on the way of thinking of decomposing the whole human body into several independent parts, which is the impetus of promoting the development of WM. The core of CM includes the holistic view and the dialectical view. Chinese herbal medicines contain various components and treat a disease from multiple targets and links. Therefore, Chinese herbal medicines treat a diseased state by regulating and mobilizing the whole body rather than just regulating a single factor, since the diseased state is not only a problem in a local part of the body but a local reflection of imbalance of the whole body.

The microstructure and interface diffusion behaviour of SiCP/Al composites prepared by high-pressure torsion under different turning numbers were investigated by OM and EDS, and the effect of turning numbers on the tensile properties and fracture mechanism was analysed combined with microstructure and interface characteristics. The results show that increasing the turns can improves the uniformity of the particles and reduces the porosity, with the Al diffusion ability enhanced and the diffusion distance increased, and the diffusion coefficient of Al is enhanced by about 1017 times in comparison with the theoretical value, leading to tensile strength and elongation of composites improved continuously and the fracture is mainly based on the ductile fracture of matrix, with a small amount of SiC particles distributed uniformly in the dimple of the fracture. When the turns come to bigger, SiC particles are broken severely by the shearing deformation, particles "regeneration and agglomeration" leads to increased porosity and more potential crack sources, forming a large quantity of new fracture interfaces with low bond strength. The tensile strength and elongation of the sample decrease greatly, and it is easy to form larger deep dimples in the agglomeration, composite fracture exhibits the mixed mode of ductile fracture and brittle fracture.

In the IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, vol. 55, no. 6, Juang et al. proposed a password-authenticated key agreement scheme using smart cards. Although the scheme of Juang et al. has many benefits, we find that it suffers from three weaknesses: 1) inability of the password-changing operation; 2) the session-key problem; and 3) inefficiency of the double secret keys. Therefore, we propose an improved scheme to overcome the weaknesses and maintain the benefits of the original scheme. In addition, our improved scheme reduces the storage and computation costs on the smart card compared with the scheme of Juang et al. We believe that our improved scheme is more suitable for real-life applications than that of Juang et al. Index Terms--Authentication, key agreement, network security, password, smart card.
