Simulation of CIECAM02 color appearance model based on Chinese color system

Color appearance model （CAM） can be used to determine the required colors for repro- duction across changes in cross-media. CIECAM02 color appearance model prediction is implemen- ted by artificial neural networks in this paper, which includes forward and reversed prediction. 1333 color samples as training samples and other 1332 color samples as test samples are selected in the Chinese color system. In order to test the prediction accuracy of neural networks after simulation of CIECAM02 color appearance model, the color-difference formula can be used for the evaluation of forward and reversed models. Results have shown that BP neural-network has acceptable accuracy in simulation of CIECAM02 color appearance model for colors of Chinese color system.

Progress in the application of ocean color remote sensing in China

After many years＇ endeavor of research and application practice, the ocean color remote sensing in China has been growing into a new technique with valuable practicality from its initiate stage of trial research. With the aim of operational service, several kinds of ocean color remote sensing application systems have been developed and realized the long-term marine environmental monitoring utilizing the real-time or near real-time satellite and airborne remote sensing data. New progresses in the technology and application of ocean color remote sensing in China are described, including the research of key techniques and the development of various application systems. Meanwhile, according to the application status and demand, the prospective development of Chinese ocean color remote sensing is brought forward. With Chinese second ocean color satellite （ HY-1 B） orbiting on 11 April 2007 and the development of airborne ocean color remote sensing system for Chinese surveillance planes, great strides will take place in Chinese ocean color remote sensing application with the unique function in marine monitoring, resources management and national security, etc.

A Pilot Study on the Correlation of Tongue Manifestation with the Site of Cerebral Infarction in Patients with Stroke

Objective：To discuss the correlation of tongue manifestation with the site of cerebral infarction in patients with acute cerebral infarction.Methods：From March 2008 to February 2009,200 cases of hospitalized patients with first unilateral cerebral infarction were chosen in the Department of Neurology,Xuanwu Hospital.The correlation of different tongue color,fur texture,fur color with the site of cerebral Infarction was analyzed.Results：The site of cerebral infarction in patients were compared between different tongue color by Chisquare test（P=0.314）,and further correspondence analysis demonstrated that there was correlation between red tongue and cortical-subcortical infarction group.The site of cerebral infarction in patients were compared between thick fur group and thin fur group,cortical-subcortical infarction occurred more frequently in the former（P=0.0008）.The site of cerebral infarction in patients were compared between dry fur group,moist fur group and smooth fur group,correspondence analysis demonstrated there was correlation between dry fur and cortical-subcortical group.The site of cerebral infarction in the patients were compared between white fur group,white-yellow fur group and yellow fur group（P=0.010）,and correspondence analysis demonstrated there was correlation between white fur and brainstem infarction;white-yellow fur has relationship with cortical infarction;subcortical infarction was weakly related with white-yellow fur;there was closer relationship between yellow fur and cortical-subcortical infarction.Conclusion：The change of tongue manifestation was associated with the site of cerebral infarction in patients,providing a new combining site for diagnosing cerebrovascular diseases by integrative medicine.
