As an important branch of telecommunication technology, digital home networks have quickly developed in recent years. Although architecture of the digital home network based on telecommunication networks has been standardized in China, only wireless access is defined to be allowable. Therefore, it becomes the focus of further research how to establish a wireless digital home network. This article proposes the concept and shows the architecture of ubiquitous access for wireless digital home networks. Moreover, key technologies for ubiquitous access are discussed here, including cognitive radio, the concept of wireless Mesh, generic link transfer mechanism, Quality of Service (QoS) guarantee mechanism, Electromagnetic Compatibility (EMC) and coexistence of heterogeneous systems. 展开更多

The paper focuses on the habits of China Web users' language utilization behaviors in accessing the Web. It also seeks to make a general study on the basic nature of language phenomenon with regard to digital accessing. A questionnaire survey was formulated and distributed online for these research purposes. There were 1,267 responses collected. The data were analyzed with descriptive statistics, Chi-square testing and contingency table analyses. Results revealed the following findings. Tagging has already played an important role in Web2.0 communication for China's Web users. China users rely greatly on all kinds of taxonomies in browsing and have also an awareness of them in effective searching. These imply that the classified languages in digital environment may aid Chinese Web users in a more satisfying manner. Highly subject-specific words, especially those from authorized tools, yielded better results in searching. Chinese users have high recognition for related terms. As to the demographic aspect, there is little difference between different genders in the utilization of information retrieval languages. Age may constitute a variable element to a certain degree. Educational background has a complex effect on language utilizations in searching. These research findings characterize China Web users' behaviors in digital information accessing. They also can be potentially valuable for the modeling and further refinement of digital accessing services. 展开更多

The initiation of the National New Drug Innovation Key Technology Program marked a strategic shift of new drug discovery in China, which will greatly enhance the new drug discovery research activities. It presents a valuable opportunity for the growth and quality advancement of pharmaceutical science journals. As the only comprehensive English journal of the Chinese Pharmaceutical Association, In the new situation, Journal of Chinese Pharmaceutical Sciences (JCPS) plays a critical role in the communication of new discoveries in pharmaceutical researches to the scientific community. To fulfill the roles as an internationally recognized platform for the communication of the new drug discoveries supported by the National New Drug Innovation Programs, the JCPS editorial office will take advantage of its English language specialty, emphasize quality and digital access, and promote the advancement of the journal. 展开更多
