A simulation of suspended sediment movement relating to tidal and wave forcing during a winter monsoon in November 1983 in the Huanghai and East China Seas continental shelf is attempted by using the model describing the cohesive/non-cohesive sediment resus-pension generated by interactions between currents and *** simulation showed that sediment concentration was increased by resuspension at shallow depths during the strong storm conditions due to high bottom stress interacted between currents and waves. This result is in general agreement with observations in horizontal distribution of suspended sediment distribution. At three current meter mooring positions off the southern Shandong Peninsula resuspension occurred only at a depth of 22 m,nearest coastal position and at deeper parts at depths of 51 and 80 m wave-current interaction effects were not significant. It has shown that the present model simulation demonstrated the capability of reproduction of suspended sediment movement under wintertime extreme event reasonably well.

Two popular traditional join algorithms and their parallel versions are introduced. When designing join algorithms in serial computing environment, decomposing inner relation is considered as the right direction to save disk I/Os. However, two different decomposition algorithms are compared, such as inner vs. outer decomposition first algorithms for tuple-based and block-based nested loop joins, showing that the proposed approach is 20% better than general approach. Also lemmas are proved, when we have to use the outer decomposition first parallel join algorithms.

Axons in central nervous system （CNS） do not regenerate spontaneously after injuries such as stroke and traumatic spinal cord iniury. Both intrinsic and extrinsic factors are responsible for the regeneration fail- ure, Although intensive research efforts have been invested on extrinsic regeneration inhibitors, the extent to which glial inhibitors contribute to the regeneration failure in viva still remains elusive. Recent exper- imental evidence has rekindled interests in intrinsic factors for the regulation of regeneration capacity in adult mammals. In this review, we propose that activating macrophages with pro-regenerative molecular signatures could be a novel approach for boosting intrinsic regenerative capacity of CNS neurons. Using a conditioning injury model in which regeneration of central branches of dorsal root ganglia sensory neu- rons is enhanced by a preceding injury to the peripheral branches, we have demonstrated that perineuronal macrophages surrounding dorsal root ganglia neurons are critically involved in the maintenance of en- hanced regeneration capacity. Neuron-derived chemokine （C-C motif） ligand 2 （CCL2） seems to mediate neuron-macrophage interactions conveying injury signals to perineuronal macrophages taking on a soley pro-regenerative phenotype, which we designate as regeneration-associated macrophages （RAMs）. Ma- nipulation of the CCL2 signaling could boost regeneration potential mimicking the conditioning injury, suggesting that the chemokine-mediated RAM activation could be utilized as a regenerative therapeutic strategy for CNS injuries.

We evaluated and compared odds ratios(OR) for ACRN between the young-adults(YA illous histology, high-grade dysplasia, or invasive ***: In the YA group, age(OR = 1.08, 95%CI: 1.06-1.09), male sex(OR = 1.26, 95%CI: 1.02-1.55), current smoking(OR = 1.37, 95%CI: 1.15-1.63), family history of colorectal cancer(OR = 1.46, 95%CI: 1.01-2.10), diabetes mellitus related factors(OR = 1.27, 95%CI: 1.06-1.54), obesity(OR = 1.23, 95%CI: 1.03-1.47), CEA(OR = 1.04, 95%CI: 1.01-1.09) and low-density lipoprotein-cholesterol(OR = 1.01, 95%CI: 1.01-1.02) were related with an increased risk of ACRN. However, age(OR = 1.08, 95%CI: 1.06-1.09), male sex(OR = 2.12, 95%CI: 1.68-2.68), current smoking(OR = 1.38, 95%CI: 1.12-1.71), obesity(OR = 1.34, 95%CI: 1.09-1.65) and CEA(OR = 1.05, 95%CI: 1.01-1.09) also increased the risk of ACRN in the OA ***: The risks of ACRN differed based on age group. Different colonoscopic screening strategies are appropriate for particular subjects with risk factors for ACRN, even in subjects younger than 50 years.
