一般評論中的徐庾文評

서보여 ( Xu Bao-yu ) 중국어문연구회 2017 中國語文論叢 Vol.0 No.79

Xu Ling(徐陵) and Yu Xin(庾信) are the most important authors in the Six Dynasties, who developed formal skills, rhetoric effects and phonetic beauty to the highest level. But the later evaluations were very difficult to balance in appraise. Some comments based on the ritual, music and political education, so they imputed the duty of national ruin to Xu Yu(徐庾). Some other based on the relationship between literary achievements and personality, debased their achievements since their some errors in the political integrity. In the Song Dynasty, with the emergence of Li Xue(理學), Xu Yu`s parallel prose got attacked once again as the sinner of literary. They despised the parallel prose just the style couldn`t accord with the principle named by Dao(道). Peoples in the Ming Dynasty liked returning to the ancient. So Xu Yu was to be discovered by the proofreading, note-offering, and annotating. The positive evaluations were increased more than before. To Qing Dynasty, the parallel prose was very flourishing. In the debating on parallel prose and prose, Xu Yu`s parallel prose was viewed as the orthodox form and taken unprecedented seriously. How to see the value of Xu Yu`s parallel prose, that formed a criticism history of Chinese literature. In some way, the level to praise or censure Xu Yu`s parallel prose reflects the level to recognize Chinese literature.

歷代文話賦話中的徐庾文評

Xu Bao Yu 중국학연구회 2017 중국학연구 Vol.- No.79

Xu Ling and Yu Xin were the most famous authors in the Six Dynasties since Zhao Ming-Wenxuan(昭明文選). No more research work has been carried out in the comments of their paralled prose(駢文). In this paper we just only discuss the comments in the theory of paralled prose and Fu(賦). In the theory of paralled prose, Wang Wenlu’s(王文祿) Wen-Mai(文脈), Lang Zhangju’s(梁章鉅) Tui-An’s Lunwen(退庵論文), Sun Mei’s(孫梅) SiLiu-Conghua(四六叢話) and Sun Deqian’s(孫德謙) Liucao-Lizhi(六朝儷指) were the important books. Among them, the two Sun’s was the master work. They basically hold positive attitude toward Xu-Yu’s(徐庾) paralled prose, which in accord with their views about paralled prose and essay. So they could break through the time, heap praise on Xu-Yu’s creation, not affected by ancient prose movement(古文運動), Song-Ming neo-confucianism(宋明理學) and the trend of classicism. In the theory of Fu(賦), there were some different judgements. The blame, such as Zhu Yao’s(祝堯) Gufu-Bianti(古賦辨體), objected the comic(俳體), modern(侓體) and Si-Liu style(四六體), defended the old form(古體). On the other side, the praise, such as Li Diaoyuan’s(李調元) Fuhua(賦話), broke away from traditional ideas and affirmed Xu-Yu’s contributions. On the whole, Qing Dynasty’s people could give the positive evaluations on Xu-Yu for their awareness of stylistic. It’s because they attached importance to it. However, since the last century new culture movement(新文化運動), the trend of criticism appeared again. They had an obvious inclination of the emphasis on content rather than on form, which still existed in the most histories of literature written by modern researchers.

The Kinetics of Anodic Dissolution and Repassivation on 316L Stainless Steel in Borate Buffer Solution Studied by Abrading Electrode Technique

( H S Xu1 ),( D B Sun ),( H Y Yu ),( H M Meng ) 한국부식방식학회(구 한국부식학회) 2015 Corrosion Science and Technology Vol.14 No.6

The capacity of passive metal to repassivate after film damage determines the development of local corrosion and the resistance to corrosion failures. In this work, the repassivation kinetics of 316L stainless steel (316LSS) was investigated in borate buffer solution (pH 9. 1) using a novel abrading electrode technique. The repassivation kinetics was analyzed in terms of the current density flowing from freshly bare 316L SS surface as measured by a potentiostatic method. During the early phase of decay (t < 2 s), according to the Avrami kinetics-based film growth model, the transient current was separated into anodic dissolution (idiss) and film formation (ifilm) components and analyzed individually. The film reformation rate and thickness were compared according to applied potential. Anodic dissolution initially dominated the repassivation for a short time, and the amount of dissolution increased with increasing applied potential in the passive region. Film growth at higher potentials occurred more rapidly compared to at lower potentials. Increasing the applied potential from 0 VSCE to 0. 8 VSCE resulted in a thicker passive film (0. 12 to 0. 52 nm). If the oxide monolayer covered the entire bare surface (θ=1), the electric field strength through the thin passive film reached 1. 6 × 107 V/cm.

Methodological Issues and Challenges in Data Collection and Analysis of Qualitative Meta-Synthesis

Yu Xu 한국간호과학회 2008 Asian Nursing Research Vol.2 No.3

Qualitative meta-synthesis is an emerging method for synthesis of findings of qualitative studies. Based on a qualitative meta-synthesis study on the lived experiences of immigrant Asian nurses working in Western countries (Xu, 2007), this paper discusses several methodological issues and challenges encountered during the data collection and analysis processes and strategies used to resolve them. These issues and challenges include, but are not limited to: adequacy of qualifying studies and inclusion criteria; availability and accessibility of qualified studies; publication bias; quality versus quantity of primary studies; studies containing both quantitative and qualitative data; studies based on identical samples; separation of relevant data for analysis; and validity of synthesis findings. The strategies used (or desired) to resolve these issues and challenges were illustrated with exemplars from the published meta-synthesis study. This paper argues and concludes that: (a) the quality of qualified available studies is more essential for a qualitative meta-synthesis study and the quality versus quantity issue must be dealt with in context and perspective; (b) creativity and flexibility consistent with the principles and spirit of qualitative inquiry is required in resolving these issues; and (c) working within multiple constraints, the meta-synthesist frequently has to settle with less than ideal solutions during the research process in the real world.

Xiao-yu Zhu,Gui-lin Cheng,Feng-hua Liu,Jin Yu,Yu-jie Wang,Tong-quan Yu,Jian-qin Xu,Ming Wang 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.7

Heat stress (HS) may induce immunosuppression as well as inhibit the proliferation of lymphocytes. This study evaluated the effects on immune function of our prescription on splenic lymphocytes under HS as well as its compatibility. The effects of four herbal extracts from Agastache rugosa, Atractylodes lancea, Cortex Phellodendri, and Gypsum Fibrosum on heat treated splenic lymphocytes were investigated and the compatibility of the prescription was also explored by using the Taguchi method. This study revealed changes in proliferation by traditional Chinese medicines of splenic lymphocytes after HS. Proliferation in the HS group was significantly lower than the control group. Under HS, the effects of higher concentrations of Agastache rugosa (100 and 200 μg/mL), Atractylodes lancea (100 and 200 μg/mL), Cortex Phellodendri (50 and 100 μg/mL) and Gypsum Fibrosum (100 and 200 μg/mL) caused a significant increase on ConA/LPS-induced proliferation of lymphocytes than lower concentrations. We, therefore, conclude that the prescription of traditional Chinese medicines may recover splenic lymphocytes from the immunosuppression induced by HS. The Taguchi design, which allows rapid and high efficiency for the selection of the best conditions for our prescription on HS-treated splenic lymphocytes, demonstrated that Agastache rugosa (200 μg/mL), Atractylodes lancea (200 μg/mL), Cortex Phellodendri (100 μg/mL) and Gypsum Fibrosum (100 μg/mL)were the optimal conditions for the prescription. The validation experiment confirmed that our composition in optimum extraction conditions enhanced effects on ConA or LPS-stimulated lymphocytes under HS. The results showed that the Taguchi optimization approach is a suitable method for optimization of the composition of prescription.

Background/Aims: Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients. Methods: We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment. Results: We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all P≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, P<0.0001). Conclusions: IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.

Prediction of the Development of Pulmonary Fibrosis Using Serial Thin-Section CT and Clinical Features in Patients Discharged after Treatment for COVID-19 Pneumonia

Yu Minhua,Liu Ying,Xu Dan,Zhang Rongguo,Lan Lan,Xu Haibo 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.6

Objective: To identify predictors of pulmonary fibrosis development by combining follow-up thin-section CT findings and clinical features in patients discharged after treatment for COVID-19. Materials and Methods: This retrospective study involved 32 confirmed COVID-19 patients who were divided into two groups according to the evidence of fibrosis on their latest follow-up CT imaging. Clinical data and CT imaging features of all the patients in different stages were collected and analyzed for comparison. Results: The latest follow-up CT imaging showed fibrosis in 14 patients (male, 12; female, 2) and no fibrosis in 18 patients (male, 10; female, 8). Compared with the non-fibrosis group, the fibrosis group was older (median age: 54.0 years vs. 37.0 years, p = 0.008), and the median levels of C-reactive protein (53.4 mg/L vs. 10.0 mg/L, p = 0.002) and interleukin-6 (79.7 pg/L vs. 11.2 pg/L, p = 0.04) were also higher. The fibrosis group had a longer-term of hospitalization (19.5 days vs. 10.0 days, p = 0.001), pulsed steroid therapy (11.0 days vs. 5.0 days, p < 0.001), and antiviral therapy (12.0 days vs. 6.5 days, p = 0.012). More patients on the worst-state CT scan had an irregular interface (59.4% vs. 34.4%, p = 0.045) and a parenchymal band (71.9% vs. 28.1%, p < 0.001). On initial CT imaging, the irregular interface (57.1%) and parenchymal band (50.0%) were more common in the fibrosis group. On the worst-state CT imaging, interstitial thickening (78.6%), air bronchogram (57.1%), irregular interface (85.7%), coarse reticular pattern (28.6%), parenchymal band (92.9%), and pleural effusion (42.9%) were more common in the fibrosis group. Conclusion: Fibrosis was more likely to develop in patients with severe clinical conditions, especially in patients with high inflammatory indicators. Interstitial thickening, irregular interface, coarse reticular pattern, and parenchymal band manifested in the process of the disease may be predictors of pulmonary fibrosis. Irregular interface and parenchymal band could predict the formation of pulmonary fibrosis early.

Finite Element Analysis and Optimization of Dither Mechanism in Dithered Ring Laser Gyroscope

Xu-dong Yu,Guo Wei,Xing-wu Long,Jian-xun Tang 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.

This paper presents an optimal structural design of dither mechanism in dithered ring laser gyroscope (DRLG) using finite element analysis (FEA). We establish an approximate theoretical model of the dithering mechanism to calculate resonant frequency and adopt the modal analysis and dynamics analysis to search the optimal solution. The validity and efficiency of the FEA are conformed by comparing with the sinusoidal and random vibration experimental results. An optimal dither mechanism is fabricated and measured experimentally. The results demonstrate the good vibration-isolated performance for the optimal design.
