In this study, we conducted a new approach to determine whether the P600 could reflect the presence of unexpected phonology. In the experiment, the critical Chinese characters in the poems are either original or substituted by homophones or synonyms. The N400 effect is observed only under the homophonic condition. Late positive shifts are revealed under both homophonic and synonymous conditions, but the amplitude under the homophonic condition is smaller than that under the synonymous condition. The observation of the N400 effect under the homophonic condition indicates that semantic processing occurs in Chinese poem comprehension, while the P600 effect elicited under the homophonic condition is a reflection of unfulfilled semantic expectations. The existence of the late positivity under the synonymous condition reveals that P600 can reflect the presence of unexpected phonology. Interestingly, late positivities under the two conditions both consist of two parts. A discussion ensues wherein these two parts of the late positive shift relate, respectively, to monitoring and resolution processes in language comprehension.

In mobile environment, because of the handheld devices' capability limitation and diversity, content adaptation becomes an essential technology for web services. In this paper, adaptation for handheld device's web access is studied. For solving the JSP resource-wrapping problem, a document type definition (DTD) is given for device independent page markup language (DIML) [1]. The problem for collecting the properties and the environment context of devices is solved by defining DTM (Device logical traits modeling). Finally we describe the adaptationprocessing algorithm by using DIML and DTM, and solve the problem for adaptation of massive HTML pages of Java-based web servers.
