Allergic rhinitis is characterized by rhinorrhea, sneezing and nasal obstruction. Allergic rhinitis increases because of developments of diagnostic techniqhe, environmental change, especially industrialization. Recently people have studied on allergic rhinitis. We studied 107 allergic rhinitis patients with SBJ from June. 2002 to December, 2002. There was a significant effect of SBJ on allergic rhinitis. So, we suggested the clinical effect of SBJ on allergic rhinitis.

The resonance control cooling system (RCCS) is the thermal tuning system for controlling the resonance frequency, 350 MHz, of the drift tube linac (DTL) in the Proton Engineering Frontier Project (PEFP). The PEFP uses 12 separate RCCS water pumping skids to control the resonance of the 20-MeV DTL (DTL21-24), 100-MeV DTL (DTL101-107) and the radio frequency quadrupole (RFQ) accelerating structures. The nominal operating inlet water temperature of the RCCS is 27 ℃and should be adjustable depending on the operational RF duty modes (21 to 33 ℃) with a stability of less than 0.1 ℃. In this work, we completed fabrication of the RCCS22-24 and the RCCS101-103. This paper discusses the fabrication, performance test, and analysis of the RCCS water pumping skids. First, the fabrication of the RCCS for the 20-MeV DTL is discussed. Second, the layout of the water pumping skid, including the selection of piping components, instrumentation and controller hardware and software, is presented. Third, the performance test of the RCCS for the 20-MeV DTL, including the continuous driving test, the function test of each components and temperature control test are achieved. Finally, empirical pressure and flow rate data from the RCCS22 water pumping tests are used to verify the design and numerical modeling of the RCCS101-103.
