The distillery wastewater of Guangdong Jiujiang Distillery, which is characteristic of containing high organic matters and rich total nitrogen, was treated by a combination of methane fermentation and denitrification/nitrification processes. 80% of COD in the raw wastewater was removed by methane fermentation at the COD volumetric loading rate of 20 kg COD/（m^3·d） using the expanded granule sludge bed （EGSB） process. However, almost all the organic nitrogen in the raw wastewater was converted into ammonia by ammonification there. Ammonia and volatile fatty acids （VFA） remaining in the anaerobically treated wastewater were simultaneously removed utilizing VFA as an electron donor by denitrification occurring in the other EGSB reactor and nitrification using PEG-immobilized nitrifying bacteria with recirculation process. An aerobic biological contact oxidization reactor was designed between denitrification/nitrification reactor for further COD removal. With the above treatment system, 18000-28000 mg/L of COD in raw wastewater was reduced to less than 100 mg/L. Also, ammonia in the effluent of the system was not detected and the system had a high removal rate for 900-1200 mg/L of TN in the raw wastewater, only leaving 400 mg/L of nitrate nitrogen.

Single crystal of BaNdMnO4 with I4/mmm was synthesized by a floating zone method. A new phase of BaNdMnO4 was obtained by annealing the single crystal in a reducing atmosphere at 573 K for 10 d. The structural change was analyzed by four-circle X-ray diffractometry and transmission electron microscopy. The new phase has an orthorhombic unit cell (Fmmm) of a=0.5486(2) nm, b=0.5484(2) nm, and c=1.3059(2) nm.

Flue gas cleaning in discharge plasma process has been studied intensivelyand we have tried to remove the NO_x and SO_2 using the wet-type plasma reactor. In this system, NOis oxidized to NO_2 and absorbed as NO_3^-, and SO_2 is absorbed as SO_3^(2-) and oxidized in theliquid to SO_4^(2-). But the concentration of NO_3^- was saturated and the absorption of NO_x andSO_2 was inhibited. Then, the reduction of NO_3^- in the liquid is required. We examined thereductive reaction of NO_3^- to NH_4^+ using discharge above the liquid surface then the pH value ofthe liquid was changed to alkaline slightly. When the Fe plate was used as a ground electrode inthe liquid, NH_4^+ was generated. Then, the relation between the generation of NH_4^+ and Fe ions(Fe^(2+) and Fe^(3+)) was studied. When Fe^(2+) was presented in the liquid, NH_4^+ was generatedand Fe^(2+) was oxidized to Fe^(3+). Fe^(2+) is required to generate NH_4^+ from NO_3^-. When NH_4^+was generated from NO_3^-, both the calculated pH value from NH_4^+ concentration and the measuredpH value indicated a similar value. From these results, the discharge above the liquid surface waseffective to convert NO_3^- to NH_4^+ and the reductive reaction leads to more absorption of NO_3^-.These results showed that the wet-type plasma reactor is effective for NO_x and SO_2 removalsystem.

Non-alcoholic fatty liver disease(NAFLD)and advanced form non-alcoholic steatohepatitis(NASH)have been become globally major chronic liver diseases(1,2).NAFLD is one of the leading causes of liver cirrhosis,hepatic failure,and hepatocellular carcinoma(HCC)(3).A large number of retrospective studies reported the importance of hepatic fibrosis with NAFLD patients as the strongest factor of liver-related mortality(4,5).On the other hand,NAFLD patients with advanced hepatic fibrosis are thought to have higer risk of developing vascular events and extrahepatic cancers because of the high prevalence of coexisting cardiometabolic risk factors,such as hypertension,diabetes mellitus,dyslipidemia,and obesity(6).However,since former literatures included only few NAFLD patients with advanced hepatic fibrosis,it is hard to estimate the accurate risk on the whole spectrum of these complications.

Several compounds of rare earth complex oxides containing manganese and titanium were synthesized in Ar, and their crystal structures were analyzed by powder X-ray diffraction data and Rietveld method. Structures of A0.67Ln0.33 Mn0.33Ti0.6703（A = Ca or Sr and Ln = rare earth） were found to have orthorhombic symmetry with the space group Pnrna, and their interatomic distances and bond angles were obtained. This space group was also derived from electron microscopic study. Electrical conductivity of Cao.67Ln0.33Mn0.33Ti0.6703 for several rare earth elements showed a semiconducting property with the activation energy of 0.4 eV. Some of these compounds of the strontium system show the antiferromagnetic properties below 10 K.

Purpose: The purpose of the present study was to determine if there were any differences in various aspects of physical activity such as energy expenditure, intensity, and type of activity between normal-weight and overweight ***: Children aged 9—12 years were recruited from 2 elementary schools located in different urban districts in Republic of Korea. The present study included 45 Korean boys, of which 19 were normal-weight and 26 were overweight. Daily physical activity was estimated over the same 1-week study period under free-living conditions using the doubly labeled water(DLW) method and a tri-axial accelerometer. Resting metabolic rate(RMR) was measured using the Douglas bag method and open-circuit indirect calorimetry. We calculated the physical activity level(PAL) as the total energy expenditure(TEE)/***: PAL was not significantly different between the groups. In the accelerometer data, time spent in locomotive moderate-to-vigorous physical activity(MVPA) was significantly lower in overweight boys than in normal-weight subjects, whereas other variables including non-locomotive activity did not differ between groups. In addition, among all participants, time spent in total locomotive activity was significantly associated with PAL. Time spent in locomotive MVPA was significantly associated with ***: Overweight boys may be less physically active based on locomotive MVPA, which was positively related with PAL. Our findings suggest that the contribution of locomotive MVPA to the increase in PAL was relatively significant.

AIM:To compare the clinicopathological characteristics of human epidermal growth factor receptor 2 (HER2)-positive and HER2-negative Barrett's adenocarcinoma in Japan. METHODS:We performed immunohistochemical analysis of HER2 in 30 samples taken from patients with Barrett's adenocarcinoma and dual color in situ hybridization in cases showing 2+ reactions. We compared the clinicopathological characteristics of HER2-positive and HER2-negative ***:HER2 positivity was identified in 8 (27%) carcinoma samples. We found that HER2 expression was associated with p53 overexpression (100% vs 52.6% in pT1 tumor; 100% vs 54.5% in all stage tumor, P < 0.05) and protruding lesions at the early disease stage. There was no association between the mucin phenotype of the carcinomas and prognosis. HER2 expression and low clinical stage were unexpectedly different between Barrett's adenocarcinoma patients and gastric cancer patients, but the macroscopic features may be associated with earlier diagnosis in these patients. CONCLUSION:Our results suggest that HER2-positive Barrett's adenocarcinomas are associated with p53 overexpression and lesion protrusion at the early disease stage.
