A novel derivative of vitamin K4, 1, 2, 4- trinaphthol- acetic ester, is synthesized by directly reacting of2- hydroxy- 1, 4- naphthoquinone with acetic anhydride, where zinc powder is used as reductant. By examiningthe influences of reacting time, temperature and reactant ratio, the esterification conditions are optimized. The ex-perimental result shows that, the esterification yield can reach 40% with a single cycle of the simple synthetic route.

A reference model for future ubiquitous convergent network is analyzed. To provide user-centric, intelligent, personalized service, this article presents a context-aware telecommunication service platform （CaTSP） to adapt to dynamically changing context. This article focuses on the new design method of context-aware telecommunication service platform and its architecture. Through the use of model-driven architecture （MDA） and semantic web technologies, CaTSP can enable context reasoning and service personalization adaption. This article explores a new approach for service intelligence, personalization, and adaptability in the semantic web service computing era.
