        Vortex-induced Vibration Control by Micro Actuator

        Bao-Qing Li,Yang Liu,Jia-Ru Chu 대한기계학회 2007 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.21 No.9

        The control of vortex-induced vibration of two side-by-side circular cylinders in a cross flow is carried out experimentally. One cylinder is elastically supported and the other is fix-supported at both ends. The two cylinders vibrate under the action of the unsteady flow-induced forces. A micro actuator is embedded on the surface of each cylinder to perturb the boundary layer. The spacing ratio is set at 1.2. The measurement shows that the structural vibration can be suppressed significantly when the reduced excitation frequency is around 2.655.

        포경 ( Bao Qing ),조량용 ( Zhao Liangyong ),한호성 ( Hosung Han ) 관광경영학회 2019 관광경영연구 Vol.87 No.-

        The paper researches the phenomenon of uncivilized conduct as well as the tourist’s morality progress and its intrinsic dynamic mechanism, which specialises in tourist behavior in the perspective of morality. The tourist is the principal part of tour activity, so that the tourist’s morality progress is the radical resolvent to the problem of tourist’s uncivilized conduct. With vast literature studies, the paper focuses on a concept of moral self which crossed Ethnics, Psychology, Education and other disciplines. The paper introduces this concept into the field of tourism research, and analyzes the concept with measurable structures, which is referred to the research ideas of Western Psychology. At the same time, the paper also discusses the philosophical origin and the identification expansion of moral self, combined with the traditional culture of China. To identify with the moral self is not only the practice path for the tourist’s moral development, but also improve the quality of tourism experience. Similar to the footprint of tourism activities, continuous expansion of identity with the moral self has contributed to the progress of the tourist’s moral development. This thesis combines the springhead of moral self based on philosophical thinking and the moral self performance of virtue quality which emphasized in Psychology, and finds out an operable way for practice and research, on the basis of that the empirical study is carried out. After gained empirical data with interview and questionnaire investigation, the paper use Structural Equation Model and other statistical analytical methods to analyze the data. Research results show that the moral self identification has a positive role in promoting the moral development and the civilized conduct of the tourist. The paper compiles a questionnaire about the moral self identification and civilized conduct of the tourist, which provides an operable tool for the related research and the practice of tourism management in future. This thesis attempts to combine the traditional thinking of moral philosopy with modern empirical research method better in the study field of Tourism Ethnics.

        Demand Response Based on Kalman-Filtering for the Frequency Control

        Yu-Qing Bao,Cheng Shen,Qi Wang,Jin-Long Zhang 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.3

        DR control can be incorporated with traditional frequency control methods to achieve better performance. However, in the frequency measurement process, disturbances may infl uence the precision of measured frequency, and further infl uence the control performance. In this paper, a hierarchical DR control strategy is considered for the frequency control. In order to reduce the infl uence of detection error, a Kalman-fi ltering based method is proposed. At last, the eff ectiveness of the proposed method is verifi ed by the testing results.

      • Golgi Phosphoprotein 2 Down-regulates the Th1 Response in Human Gastric Cancer Cells by Suppressing IL-12A

        Tang, Qing-Feng,Ji, Qing,Tang, Yu,Hu, Song-Jiao,Bao, Yi-Jie,Peng, Wen,Yin, Pei-Hao Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

        Golgi phosphoprotein 2 (GOLPH2) is a very important biomarker in a variety of diseases. Its biological function is not clear, particularly in gastric cancer. To investigate the role of GOLPH2 in human gastric cancer, and determine its effect on the Th1 lymphocyte response, its expression and that of IL-12A were measured by real-time PCR and immunohistochemistry. The relationship between GOLPH2 and IL-12A was analysed statistically. The effect of GOLPH2 on the Th1 lymphocyte response was investigated with an in vitro co-culture system. The results showed that in human gastric cancer, the expression of GOLPH2 was significantly higher and the expression of IL-12A was lower than in normal gastric mucosal tissues, and the expression levels of GOLPH2 and IL-12A were negatively correlated. In addition, obvious down-regulation of the Th1 response was observed when lymphocytes were co-cultured with gastric cancer SGC7901 cells over-expressing GOLPH2. GOLPH2 down-regulated the expression of IL-12A, and inhibited the expression of TNF-${\alpha}$ and IFN-${\gamma}$. The results indicated that GOLPH2 down-regulates the Th1 response via suppression of IL-12A in human gastric cancer, and this might provide a target for the prevention and treatment.

      • Prognostic Role of Hepatoma-derived Growth Factor in Solid Tumors of Eastern Asia: a Systematic Review and Meta-Analysis

        Bao, Ci-Hang,Liu, Kun,Wang, Xin-Tong,Ma, Wei,Wang, Jian-Bo,Wang, Cong,Jia, Yi-Bin,Wang, Na-Na,Tan, Bing-Xu,Song, Qing-Xu,Cheng, Yu-Feng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.5

        Hepatoma-derived growth factor (HDGF) is a novel jack-of-all-trades in cancer. Here we quantify the prognostic impact of this biomarker and assess how consistent is its expression in solid tumors. A comprehensive search strategy was used to search relevant literature updated on October 3, 2014 in PubMed, EMBASE and WEB of Science. Correlations between HDGF expression and clinicopathological features or cancer prognosis was analyzed. All pooled HRs or ORs were derived from random-effects models. Twenty-six studies, primarily in Eastern Asia, covering 2,803 patients were included in the analysis, all of them published during the past decade. We found that HDGF overexpression was significantly associated with overall survival (OS) ($HR_{OS}=2.35$, 95%CI=2.04-2.71, p<0.001) and disease free survival (DFS) ($HR_{DFS}=2.25$, 95%CI =1.81-2.79, p<0.001) in solid tumors, especially in non-small cell lung cancer, hepatocellular carcinoma and cholangiocarcinoma (CCA). Moreover, multivariate survival analysis showed that HDGF overexpression was an independent predictor of poor prognosis ($HR_{OS}=2.41$, 95%CI: 2.02-2.81, p<0.001; $HR_{DFS}=2.39$, 95%CI: 1.77-3.24, p<0.001). In addition, HDGF overexpression was significantly associated with tumor category (T3-4 versus T1-2, OR=2.12, 95%CI: 1.17-3.83, p=0.013) and lymph node status (N+ versus N-, OR=2.37, 95%CI: 1.31-4.29, p=0.03) in CCA. This study provides a comprehensive examination of the literature available on the association of HDGF overexpression with OS, DFS and some clinicopathological features in solid tumors. Meta-analysis results provide evidence that HDGF may be a new indicator of poor cancer prognosis. Considering the limitations of the eligible studies, other large-scale prospective trials must be conducted to clarify the prognostic value of HDGF in predicting cancer survival.

        Early Changes in Apparent Diffusion Coefficient for Salivary Glands during Radiotherapy for Nasopharyngeal Carcinoma Associated with Xerostomia

        Qing Zhang,Yu-Mei Wei,Yuan-Gang Qi,Bao-Sheng Li 대한영상의학회 2018 Korean Journal of Radiology Vol.19 No.2

        Objective: To evaluate the early changes in the apparent diffusion coefficient (ADC) of the salivary glands during radiotherapy (RT) and their association with the degree of xerostomia at 6 months after RT in patients with nasopharyngeal carcinoma (NPC). Materials and Methods: We enrolled 26 patients with NPC who underwent RT. Each patient underwent diffusion-weighted MRI of the salivary glands at rest and with gustatory stimulation within 1 week before RT and 2 weeks after the beginning of RT. The ADC at rest (ADCR) and increase and increase rate with stimulation (ADCI, ADCIR) of the submandibular and parotid glands were calculated. The differences in the variables’ values between 2 weeks after the beginning of RT and baseline (ΔADCR, ΔADCI, and ΔADCIR) were compared to the degree of xerostomia at 6 months after RT. Results: The ADCR of the submandibular and parotid glands were both significantly higher at 2 weeks after the beginning of RT than found at baseline (both p < 0.01). The ADCI and ADCIR for the parotid glands were both significantly lower at 2 weeks after the beginning of RT than found at baseline (both p < 0.01). ΔADCI and ΔADCIR of the parotid glands were associated with the degree of xerostomia at 6 months after RT (r = -0.61 and -0.72, both p < 0.01). Conclusion: The ADCs of the salivary glands change early during RT. The differences in the ADC increase and increase rate of the parotid glands between 2 weeks after the beginning of RT and baseline were associated with the degree of xerostomia at 6 months after RT.

        Mesoporous CexZr1−xO2 solid solutions supported CuO nanocatalysts for toluene total oxidation

        Qing-Fang Deng,Tie-Zhen Ren,Bao Agula,Yuping Liu,Zhong-Yong Yuan 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.5

        Mesoporous CexZr1 xO2 solid solutions were prepared by the surfactant-assisted method and used as support of CuO nanocatalysts for catalytic total oxidation of toluene. The prepared CuO/CexZr1 xO2 catalysts have a wormhole-like mesoporous structure with high surface area and uniform pore size distribution, and the CuO nanoparticles were highly dispersed on the surface of CexZr1 xO2. The doping of ZrO2 in CeO2 promotes the dispersion of active copper species and enhances the reducibility of copper species. The effect of Ce/Zr ratio, calcination temperature and CuO loading amount on the catalytic performance of CuO/CexZr1 xO2 was investigated in detail. The 400 ℃-calcined 8%CuO/Ce0.8Zr0.2O2 catalyst exhibits the highest activity with the complete toluene conversion temperature of 275 ℃ at the condition of GHSH = 33,000 h-1 and the toluene concentration of 4400 ppm. The interfacial interaction between CuO and the CexZr1 xO2 support, highly dispersed CuO nanoparticles and the nature of the support contribute to the high catalytic activity of mesoporous CuO/CexZr1 xO2 nanocatalysts.

        Qing-Lin Lou,Xiao-Jun Ouyang,Liu-Bao Gu,Yong-Zhen Mo,Ronald Ma,Jennifer Nan,Alice Kong,Wing-Yee So,Gary Ko,Juliana Chan,Chun-Chung Chow,Rong-Wen Bian 대한당뇨병학회 2012 Diabetes and Metabolism Journal Vol.36 No.6

        Background: To determine the frequency of chronic kidney disease (CKD) and its associated risk factors in Chinese type 2 diabetic patients, we conducted a cross-sectional study in Nanjing, China, in the period between January 2008 and December 2009. Methods: Patients with type 2 diabetes under the care by Jiangsu Province Official Hospital, Nanjing, China were invited for assessment. CKD was defined as the presence of albuminuria or estimated glomerular filtration rate <60 mL/min/1.73 m2. Albuminuria was defined as urinary albumin-to-creatinine ratio ≥30 mg/g. Results: We recruited 1,521 urban Chinese patients with type 2 diabetes (mean age, 63.9±12.0 years). The frequency of CKD and albuminuria was 31.0% and 28.9%, respectively. After adjusted by age and sex, hypertension, anemia and duration of diabetes were significantly associated with CKD with odds ratio (95% confidence interval) being 1.93 (1.28 to 2.93), 1.70 (1.09 to 2.64), and 1.03 (1.00 to 1.06), respectively. Conclusion: In conclusion, CKD was common in the urban Nanjing Chinese with type 2 diabetes. Strategies to prevent or delay progression of kidney disease in diabetes should be carried out at the early disease course of type 2 diabetes.

        Purification and Characterization of an Acid Deoxyribonuclease from the Cultured Mycelia of Cordyceps sinensis

        ( Mao Qing Ye ),( Zheng Hu ),( Ying Fan ),( Ling He ),( Fu Bao Xia ),( Guo Lin Zou ) 생화학분자생물학회 2004 BMB Reports Vol.37 No.4

        A new acid deoxyribonuclease (DNase) was purified from the cultured mycelia of Cordyceps sinensis, and designated CSDNase. CSDNase was purified by (NH₄)₂SO₄ precipitation, Sephacryl S-100 HR gel filtration, weak anion-exchange HPLC, and gel filtration HPLC. The protein was single-chained, with an apparent molecular mass of ca. 34 kDa, as revealed by SDS-PAGE, and an isoelectric point of 7.05, as estimated by isoelectric focusing. CSDNase acted on both double-stranded (ds) and single- stranded (ss) DNA, but preferentially on dsDNA. The optimum pH of CSDNase was pH 5.5 and its optimum temperature 55. The activity of CSDNase was not dependent on divalent cations, but its enzymic activity was inhibited by high concentration of the cation: MgC1₂ above 150 mM, MnCl₂ above 200 mM, ZnCl₂ above 150 mM, CaCl₂ above 200 mM, NaCl above 300 mM, and KCI above 300 mM. CSDNase was found to hydrolyze DNA, and to generate 3-phosphate and 5-OH termini. These results indicate that the nucleolytic properties of CSDNase are essentially the same as those of other well-characterized acid DNases, and that CSDNase is a member of the acid DNase family. To our knowledge, this is the first report of an acid DNase in a fungus.
