        近代知識體系下的職業人群與社會網絡 -對上海震旦大學的考察-

        ( Xue Qiang Ma ) 국민대학교 중국지식네트워크 2012 중국지식네트워크 Vol.2 No.-

        近代中國知識體系的構建非常復雜, 從晩淸到民國, 所稱的“西學”, “新學”, 其形式·內容都發生了흔大的變化。本文以上海震旦爲例, 詳細解讀近代學校的新知識體系構建及其變化。從徐家匯到盧家灣, 由學院到大學, 震旦屢經變遷, 從震旦各個時期的章程·大綱·敎學計劃·歷年課程表·各科敎材講義, 以及當年刊印的震旦課本·震旦出版物中, 淸석地勾勒出震旦新知識體系的構建與선變。隨著近代知識的專業化, 直接推動了接受近代知識人群的職業化。在震旦大學新構建的知識體系中, 催生出不少新的職業人群, 出現了諸如律師·法官·西醫·會計師·經濟師·工程師·設計師, 還有職業經理人, 等等, 近代職業人群與近代中國城市發展需求相適應。與此同時, 那些接受了新知識的職業人群, 在他們的人際關系中, 又多了壹層同學關系, 背後還有廣泛的校友網絡。 It is very complex to construct the knowledge system in modern times. The socalled Western Learning had changed a great deal from the Late Qing Dynasty to the Republic of China both in form and content. Taking the Aurora University for example, this paper has detailedly analyzed how the new knowledge system had been built and how had changed in modern times. The Aurora University had changed greatly in places from Xujiahui to Lujiawan, as well as in its level from a College to an University, which is clearly outlined by the study based on the regulations, teaching programms, plans in different times, curriculums over the years, various textbooks and teaching materials including the publications in those days. And the specialization of modern knowledge system had directly promote a new occupation population. As the Aurora University for example, the new professional population had arised in various fields, such as lawyer, judge, western medicine, accountant, economic manager, engineer, designer, professional manager and so on, which was adapted to the social development of modern city. Meanwhile, the interpersonal relationship of this population had added a new relationship of schoolmates. In other words, there were wide alumni networks behind these people.

        Xue-Song Sun,Di-Han Liu,Sai-Lan Liu,Qiu-Yan Chen,Shan-Shan Guo,Yue-Feng Wen,Li-Ting Liu,Hao-Jun Xie,Qing-Nan Tang,Yu-Jing Liang,Xiao-Yun Li,Jin-Jie Yan,Ming-Huang Hong,Jun Ma,Lin-Quan Tang,Hai-Qiang M 대한암학회 2019 Cancer Research and Treatment Vol.51 No.4

        Purpose The purpose of this study was to investigate the survival trends and patterns of failure in patients with stage II nasopharyngeal carcinoma (NPC) treated with radiotherapy (RT) and chemotherapy over the last 20 years. Materials and Methods Thirty-eight hundred and eight patients diagnosed with stage II NPC between January 1990 and December 2012 were involved in this retrospective cohort study. All patients were treated with RT. According to the main imaging techniques and RT technology, we categorized these patients into four calendar periods: 1990-1996, 1997-2002, 2003-2007, and 2008-2012. Overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), and distant metastasis–free survival (DMFS) were served as the clinical outcome. Results After a median follow-up period of 84.7 months, we observed increasing trends in survival and disease control. The 3- and 5-year OS rates increased from 87.1% and 78.7% in the first calendar period to 97.4% and 94.5% in the last calendar period, respectively (p < 0.001). Additionally, significant increasing trends could be seen in the PFS and LRFS during the four calendar periods. In the subgroup analysis, the LRFS in patients older than 50 years at diagnosis showed greater improvement than younger patients. However, the rate of distant metastasis was stable and relatively low, as the 5-year DMFS ranged from 90.5% to 94.7% among the four calendar periods. Conclusion The survival rates in patients with stage II NPC showed increasing trends from 1990 to 2012. The advance of RT provided excellent locoregional control and enhanced OS.

        A method of determining test load for full-scale wind turbine blade fatigue tests

        Qiang Ma,Zongwen An,Jianxiong Gao,Hai-Xia Kou,Xue-Zong Bai 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.11

        Full-scale fatigue test is an effective method for validating the fatigue performance of wind turbine blade. Its primary problem is how to design the test load. The conventional approach to determine test load requires a complicated and time-consuming process. Thus, a simplified method for directly converting load spectrum of blade into test load is proposed in this paper. Firstly, beam theory is used to obtain the relationship between stress, strain and bending moment of blade cross section. Based on the assumption of local stress concentration and linear relationship between stress and strain, M-N curves (applied moment vs. allowable number of cycles to failure) is defined. Secondly, based on Miner's linear cumulative damage theory and constant life diagram, the equivalent fatigue cumulative damage of load spectrum which is equal to the damage of full-scale fatigue test is obtained. Then, in the case of the selected test load ratio and cycles, the mean and amplitude of test load can be solved. Finally, the validity of the proposed method is verified by an illustrative example. The result indicates that the error of the calculated results between this method and the traditional method is close to 5 %, and it can be used for fatigue test and improve the efficiency of test load design.

        Enhancing Astaxanthin Accumulation in Haematococcus pluvialis by Coupled Light Intensity and Nitrogen Starvation in Column Photobioreactors

        ( Wen-wen Zhang ),( Xue-fei Zhou ),( Ya-lei Zhang ),( Peng-fei Cheng ),( Rui Ma ),( Wen-long Cheng ),( Hua-qiang Chu ) 한국미생물 · 생명공학회 2018 Journal of microbiology and biotechnology Vol.28 No.12

        Natural astaxanthin mainly derives from a microalgae producer, Haematococcus pluvialis. The induction of nitrogen starvation and high light intensity is particularly significant for boosting astaxanthin production. However, the different responses to light intensity and nitrogen starvation needed to be analyzed for biomass growth and astaxanthin accumulation. The results showed that the highest level of astaxanthin production was achieved in nitrogen starvation, and was 1.64 times higher than the control group at 11 days. With regard to the optimization of light intensity utilization, it was at 200 μmo/m2/s under nitrogen starvation that the highest astaxanthin productivity per light intensity was achieved. In addition, both high light intensity and a nitrogen source had significant effects on multiple indicators. For example, high light intensity had a greater significant effect than a nitrogen source on biomass dry weight, astaxanthin yield and astaxanthin productivity; in contrast, nitrogen starvation was more beneficial for enhancing astaxanthin content per dry weight biomass. The data indicate that high light intensity synergizes with nitrogen starvation to stimulate the biosynthesis of astaxanthin.

        Layer-by-layer Self-assembly Polyurethane/TiO2 NPs Hybrid Film and Its Photocatalytic Efficiency for Decolorization of Methyl Blue

        Yijiong Liu,Juanqin Xue,Yinli Duan,Liang-Sheng Qiang,Jing Ma 한국섬유공학회 2019 Fibers and polymers Vol.20 No.9

        In this study, Layer-by-layer (LbL) self-assembly technique was used to fabricate TiO2 films onto glass slides. Polyurethane (PU) was used as a substrate for the immobilization of TiO2, to increase the adsorption ability of thephotocatalyst. The LBL sequence was (PU/TiO2 NPs)n (n is the number of bilayers). These LbL hybrid films werecharacterized by Raman spectra, which confirmed the formation of TiO2 nanoparticles (TiO2 NPs) in the anatase phase withaverage size around 30 nm. The thickness of the film estimated around 1.1±0.2 μm as determined by scanning electronmicroscopy (SEM). UV-vis spectra confirmed the linear and regular growth of the films with the number of bilayers. Thephotocatalytic property of the films was investigated by the decomposition of methyl blue (MB) under UV-light irradiation. Furthermore, the reusability studies revealed that the fabricated film could be repeatedly used for up to six times withoutaffecting the photocatalytic activity. In addition, the corresponding mechanism of enhanced photocatalytic activity wasproposed on the basis of the investigated results from reactive species scavenging of (PU/TiO2 NPs)10. The active species h+played the most important role in the photocatalytic reaction. This work manifested that the LbL films can be handled moreeasily than TiO2 NPs in suspension form. Therefore, as-synthesized film is a promising candidate in wastewater treatmentapplication.

        Facile Synthesis of Thermo-responsive TiO2/PNIPAM Composite with Switchable Photocatalytic Performance

        Yinli Duan,Jing Ma,Jiao Liu,Liang-Sheng Qiang,Juanqin Xue 한국섬유공학회 2020 Fibers and polymers Vol.21 No.4

        In this paper, a facile and efficient method was performed to prepare the thermo-responsive Poly(Nisopropylacrylamide)/TiO2 (TiO2/PNIPAM) with the dispersing of TiO2 nanoparticles into PNIPAM. The structures ofnanoparticles and the grafted polymer were confirmed by X-ray diffraction (XRD), Raman spectra, Fourier transforminfrared spectra (FT-IR) and Dynamic Light Scattering (DLS). The interactions between the two components were studied byX-ray photoelectron spectroscopy (XPS), and the morphology of TiO2/PNIPAM was observed by scanning electronmicroscopy (SEM). The results showed that TiO2 exhibited homogeneous dispersion, without sacrificing the properties ofTiO2. Furthermore, The composite was used to photocatalytic degradation of Methylene blue (MB). The highest MB removalefficiency is 86.3 %. The photocatalytic activities above or below the lower critical solution temperature (LCST) of PNIPAMwas also investigated. The experiment results show that the existence of PNIPAM contributed not only the thermo-responsiveabilities to TiO2, but also the enhanced photocatalytic activities to TiO2. In addition, the corresponding mechanism ofenhanced photocatalytic activity was proposed. The results manifest that the well-designed TiO2/PNIPAM is a promisingcandidate in wastewater treatment application.

        Ji, Tian-Xing,Zhi, Cheng,Guo, Xue-Guang,Zhou, Qiang,Wang, Guo-Qiang,Chen, Bo,Ma, Fei-Fei Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.14

        Background: Previous studies investigating the association between miR-34b/c rs4938723 polymorphism and cancer risk showed inconclusive. Here, we performed meta-analysis to investigate the association between miR- 34b/c rs4938723 polymorphism and digestive cancer risk. Materials and Methods: Literature database including PubMed, OVID, Chinese National Knowledge Infrastructure (CNKI) were searched for publications concerning the association between the miR-34b/c rs4938723 polymorphism and digestive cancer risk. Results: A total of 6 studies consisting of 3246 cases and 3568 controls were included in this meta-analysis. The combined analysis suggested the miR-34b/c rs4938723 polymorphism significantly reduced digestive cancer risk under allelic model, homogeneous co-dominant model and recessive model (C vs T: OR=0.88, 95%CI=0.82-0.95, p-value=0.001; CC vs TT: OR =0.67, 95%CI=0.57-0.80, p-value=0.000; CC vs TT/TC: OR=0.68, 95%CI=0.58-0.80, p-value=0.000). Q-test and I2 test revealed no significant heterogeneity in all genotype comparisons. The Begger's funnel plot and Egger's test did not show significant publication bias. Conclusions: The current evidence supports the conclusion that the miR-34b/c rs4938723 polymorphism decreases an individual's susceptibility to digestive cancers.

        Zeng-ru Zhao,Xin Wang,Xue-feng Zhang,Qiang Ma,Yan-li Liu,Yong-feng Li,Fei Liu,Gao-feng Wang 한국자기학회 2017 Journal of Magnetics Vol.22 No.1

        Mischmetal of Bayan Obo ore was utilized to prepare the high performance (Pr7.34Nd21.86)1-xMMxFe68.7Al0.1-Cu0.12Co0.88B ribbons using melt-spinning method. Phase composition and magnetic properties were investigated at room temperature. The ribbons mainly consist of R2Fe14B phase in isotropic nanostructure. Both coercivity and maximum energy product decrease with the increase of MM content. The magnetic parameters of the ribbons with MM = 20 % in mass are Br = 7.38 kGs, Hcj = 13.66 kOe, (BH)max = 11.81 MGOe. Henkel plots were applied to demonstrate the exchange coupling interaction between grains.

      • Integrin-linked Kinase Functions as a Tumor Promoter in Bladder Transitional Cell Carcinoma

        Wang, De-Lin,Lan, Jian-Hua,Chen, Liang,Huang, Biao,Li, Zeng,Zhao, Xiu-Min,Ma, Qiang,Sheng, Xia,Li, Wen-Bin,Tang, Wei-Xue Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.6

        The aim of this study was to elucidate the role of the integrin-linked kinase (ILK) gene in development of human bladder transitional cell carcinoma (BTCC). Expression of ILK protein and ILK mRNA in 56 cases of human BTCC tissue and in 30 cases of adjacent normal bladder tissue was detected by immunohistochemistry S-P and reverse transcription polymerase chain reaction (RT-PCR), respectively. Four specific miRNA RNAi vectors targeting human ILK were synthesized and transfected into BIU-87 cells by liposome to obtain stable expression cell strains. The influence of ILK on proliferation of BTCC was detected by MTT, FCM on athymic mouse tumorigenesis. The positive rate of ILK protein in BTCC tissue (53.6%) was much higher than adjacent normal bladder tissue (10.0%) (p<0.05). Similarly, expression of ILK mRNA in BTCC tissue ($0.540{\pm}0.083$) was significantly higher than in adjacent normal bladder tissue ($0.492{\pm}0.070$) (p<0.05). MTT showed that the proliferation ability of miRNA-ILK transfected group was clearly decreased (p<0.05), the cell cycle being arrested in G0/G1-S, an tumorigenesis in vivo was also significantly reduced (p<0.05). ILK gene transcription and protein expression may be involved in the development of BTCC, so that ILK might be the new marker for early diagnosis and the new target for gene treatment.

        Induction Chemotherapy Plus Concurrent Chemoradiotherapy versus Concurrent Chemoradiotherapy Alone in Locoregionally Advanced Nasopharyngeal Carcinoma in Children and Adolescents: A Matched Cohort Analysis

        Yang Li,Lin-Quan Tang,Li-Ting Liu,Shan-Shan Guo,Yu-Jing Liang,Xue-Song Sun,Qing-Nan Tang,Jin-Xin Bei,Jing Tan,Shuai Chen,Jun Ma,Chong Zhao,Qiu-Yan Chen,Hai-Qiang Mai 대한암학회 2018 Cancer Research and Treatment Vol.50 No.4

        Purpose The purpose of this study was to evaluate the long-term clinical outcome and toxicity of induction chemotherapy (IC) followed by concomitant chemoradiotherapy (CCRT) compared with CCRT alone for the treatment of children and adolescent locoregionally advanced nasopharyngeal carcinoma (LACANPC). Materials and Methods A total of 194 locoregionally advanced nasopharyngeal carcinoma patients younger than 21 years who received CCRT with or without IC before were included in the study population. Overall survival (OS) rate, progression-free survival (PFS) rate, locoregional recurrence-free survival (LRFS) rate, and distant metastasis-free survival (DMFS) rate were assessed by the Kaplan-Meier method and a log-rank test. Treatment toxicities were clarified and compared between two groups. Results One hundred and thiry of 194 patients received IC+CCRT. Patients who were younger and with more advanced TNM stage were more likely to receive IC+CCRT and intensive modulated radiotherapy. The addition of IC before CCRT failed to improve survival significantly. The matched analysis identified 43 well-balanced patients in both two groups. With a median follow-up of 51.5 months, no differences were found between the IC+CCRT group and the CCRT group in 5-year OS (83.7% vs. 74.6%, p=0.153), PFS (79.2% vs. 73.4%, p=0.355), LRFS (97.7% vs. 88.2%, p=0.083), and DMFS (81.6% vs. 81.6%, p=0.860). N3 was an independent prognostic factor predicting poorer OS, PFS, and DMFS. The addition of IC was associated with increased rates of grade 3 to 4 neutropenia. Conclusion This study failed to demonstrate that adding IC before CCRT could provide a significant additional survival benefit for LACANPC patients. Further investigations are warranted.
