| 1 | 基于扎根理论的高校“水课”教育改革研究显示文摘高校中普遍存在的'水课'现象引起了社会各界的广泛关注。'水课'的存在导致学生无法从教学内容中有效地学到专业知识,浪费他们的时间与精力,同时也意味着学校教学资源的浪费。尽管'水课'现象已经引起了人们的关注,但是目前教育领域的学者却极少关注这种现象。文章使用扎根理论的方法来研究'水课'现象,试图探索出'水课'存在的导因,并据此为我国的高校教育改革提出有科学依据的建议。研究发现,大学生一般会将具有重复性内容的课程、任课教师授课不专业、考核方式过于简单的课程视为'水课'。鉴于此,在深化教育改革过程中,需要在树立课程考核方式,注重提升教师专业水平,重视学生意见等方面深挖完善举措。 | Jhony Choon Yeong Ng 陈红雪 宋凯文 谭清美 夏后学 | 2017 | 高教学刊2017，3，22： | 27 |
| 2 | 利他主义与利他行为:三个年龄群体的扎根理论研究显示文摘已有文献出现了冠以利他行为之名的助人行为研究以及假定利他主义和利他行为的可替换性的混乱局面。鉴于此,采用经典扎根理论的方法,针对高中生、大学生、职场人士这三个年龄群体,在中国的情境下,重新探讨利他主义的本质以及利他主义和利他行为之间的影响机制。研究发现,受访者都具有一定高水平的利他主义,但意外的是,利他主义似乎不影响利他行为的产生。受访者在决定是否助人时,主要考虑的是自己是否有能力助人,以及他们的核心利益是否会被触犯。西方文献所主张的个体助人行为主要受其同情心及行为前成本效益分析影响的观点并未得到支持。本研究不仅颠覆了许多西方学者的观点,而且增添了中国情境的理论观点。 | Jhony Choon Yeong Ng 郑佳 贾良定 谭清美 | 2018 | 中国青年研究2018，，7： | 24 |
| 3 | 一群去专业化的人——斜杠青年的事业发展研究显示文摘'斜杠青年'的概念在2016年初被引入中国,并影响了数十万年轻人从事多重职业。然而随着现代社会的发展,各行各业的分工越来越细化,职业专业化程度越来越高。在这种专业化的背景下,斜杠青年这种去专业化的职业模式为何能迅速发展的问题亟待研究。本文采用扎根理论的方法 ,对不同地区、不同年龄段的38位工作者进行深入访谈,对斜杠青年这一群体的动因、特征、发展进行探索性研究。研究发现斜杠青年渴望实现自身价值,渴望多姿多彩的生活,并且具备强项是所在专业的边缘技能、技能精进是工作的主要目标两大特征,未来事业发展方向是以技能创业。本文认为,斜杠青年这类去专业化的人群,在企业中不是核心人员,但不可缺少,因此希望日后管理研究能够重视斜杠青年,并且寻求对这类人群的管理方法。 | Jhony Choon Yeong Ng 邵丹慧 贾良定 谭清美 | 2018 | 中国人力资源开发2018，35，6： | 23 |
| 4 | 大学生志愿者志愿行为可持续性研究显示文摘近年来,学者从志愿动机角度探究了影响志愿行为可持续性的因素,从物质和精神两方面构建了大学生志愿者的激励机制,但所取得的效果并不理想。运用经典扎根理论,针对大学生志愿者志愿动机、志愿行为以及志愿服务结束后的后续行为的访谈发现,志愿动机不一定产生志愿行为,志愿者的内心定额、志愿经历储备对于志愿行为的反向作用。 | Jhony Choon Yeong Ng 赵斯琪 谭清美 | 2019 | 当代青年研究2019，0，6： | 19 |

| 6 | Perfusion magnetic resonance imaging of the liver显示文摘Perfusion magnetic resonance imaging (MRI) studies quantify the microcirculatory status of liver parenchyma and liver lesions, and can be used for the detection of liver metastases, assessing the effectiveness of antiangiogenic therapy, evaluating tumor viability after anticancer therapy or ablation, and diagnosis of liver cirrhosis and its severity. In this review, we discuss the basic concepts of perfusion MRI using tracer kinetic modeling, the common kinetic models applied for analyses, the MR scanning techniques, methods of data processing, and evidence that supports its use from published clinical and research studies. Technical standardization and further studies will help to establish and validate perfusion MRI as a clinical imaging modality. | Choon Hua Thng Tong San Koh David J Collins Dow Mu Koh | 2010 | World Journal of Gastroenterology2010，16，13： | 15 |
| 7 | Hydrogen sutfide protects colon cancer cells from chemopreventative agent β-phenylethyl isothiocvanate induced apoptosis显示文摘AIM: Hydrogen sulfide (H2S) is a prominent gaseous constituent of the gastrointestinal (GI) tract with known cytotoxic properties. Endogenous concentrations of H2S are reported to range between 0.2-3.4 mmol/L in the GI tract of mice and humans. Considering such high levels we speculate that, at non-toxic concentrations, H2S may interact with chemical agents and alter the response of colonic epithelium cells to such compounds. The GI tract is a major site for the absorption of phytochemical constituents such as isothiocyanates, flavonoids, and carotenoids, with each group having a role in the prevention of human diseases such as colon cancer. The chemopreventative properties of the phytochemical agent β-phenyethyl isothiocyanate (PEITC) are well recognized. However, little is currently known about the physiological or biochemical factors present in the GI tract that may influence the biological properties of ITCs. The current study was undertaken to determine the effects of H2S on PEITC mediated apoptosis in colon cancer cells.METHODS: Induction of apoptosis by PEITC in human colon cancer HCT116 cells was assessed using classic apoptotic markers namely SubG1 population analysis,caspase-3 like activity and nuclear fragmentation and condensation coupled with the MTT (3-(4,5-dimethylthiazol2-yl)-2,5-diphenyl tetrasodium bromide) viability assay and LDH leakage.RESULTS: PEITC significantly induced apoptosis in HGT116cells as assessed by SubG1 population formation, nuclear condensation, LDH leakage and caspase-3 activity after 24 h, these data being significant from control groups (P<0.01). In contrast, co-treatment of cells with physiological concentrations of H2S (0.1-1 mmol/L) prevented PEITC mediated apoptosis as assessed using the parameters described.CONCLUSION: PEITC effectively induced cell death in the human adenocarcinoma cell line HCT116 in vitro through classic apoptotic mechanisms. However, in the presence of H2S, apoptosis was abolished. These data suggest that H2S may play a significant role in the response of colonic epithelial cells to beneficial as well as toxic agents present within the GI tract. | Peter Rose Philip K Moore Shen Han Ming Ong Choon Nam Jeffrey S Armstrong Matt Whiteman | 2005 | World Journal of Gastroenterology2005，11，26： | 13 |
| 8 | 信息化对老年人生活影响研究——基于智能手机使用情况与感受显示文摘目前中国的信息化正快速发展,当社会享受信息化带来的好处时,老年人未必能够适应信息化社会,反而面临种种不便。故采用经典扎根理论,通过半结构式访谈收集信息,针对信息化对老年人的生活影响开展研究。研究发现:①对于信息化水平较低的老年人来说,信息化对其影响好坏取决于其儿女的关心程度。②对于信息化水平较高的老年人,信息化为其带来丰富的资源,但也造成了身体伤害、与儿女缺乏交流、信息安全隐患等负面影响。基于以上发现,从儿女赡养、城乡一体化建设、老年信息化培训、开发老年信息化市场四个方面提出建议,期望降低信息化对老年人的负面影响。 | JHONY CHOON YEONG NG 陈思璇 谭清美 | 2019 | 南京航空航天大学学报(社会科学版)2019，21，2： | 12 |
| 9 | 国外典型军民融合发展模式的借鉴和启示显示文摘军民融合是一个不断深化、自主创新的过程。然而,借鉴发达国家军民融合发展的模式和政策是必要的、有意义的。典型国家如美国、俄罗斯、英国等基本上都经历了'军民分离'到'以军养民'再到'军民融合'的发展历程。通过分析典型国家军民融合发展的动因、模式和政策,可以得到一些启示:一是建立军民产品统一标准规范,消除军民融合的技术壁垒;二是健全军民两用技术发展的法律、法规和政策;三是实现军民融合政策与经济社会发展实践相协调;四是选择适合本国国情和军情的军民融合发展模式。 | 谭清美 杨凌波 Jhony Choon Yeong Ng | 2018 | 南京理工大学学报(社会科学版)2018，31，2： | 7 |
| 10 | 基于“三条链”的无人机产业军民融合发展途径与策略显示文摘军民融合是国家重大发展战略,现有文献主要关注军民融合过程中的具体问题,缺乏综合性分析。基于产业生态系统“三条链”视角,以无人机产业为例,通过构建无人机产业生态系统的“三条链”,深入探讨无人机产业军民融合发展途径和策略。研究发现,从创新链角度构建军民融合研发创新平台、从产业链角度生产军民两用无人机、从价值链角度在研发环节成立技术联盟、在销售环节合力扩大彼此销售范围是无人机产业军民融合发展的有效途径和策略,该结论同样对其它产业军民融合发展具有指导作用。 | 谭清美 马俊华 Jhony Choon Yeong Ng | 2019 | 科技进步与对策2019，36，14： | 7 |
| 11 | Trigonelline protects the cardiocyte from hydrogen peroxide induced apoptosis in H9c2 cells显示文摘Objective:To elucidate the key parameters associated with hydrogen peroxide induced oxidative stress and investigates the mechanism of trigonelline(TG)for reducing the H_2O_2induced toxicity in H9c2 cells.Methods:Cytotoxicity and antioxidant activity of TG was assessed by EZ-CYTOX kit.RNA extraction and cDNA synthesized according to the kit manufacture protocol.Apoptosis was measured by the Flowcytometry,general PCR and qPCR.Results:It was found that the TG significantly rescued the morphology of the H9c2 cells.Treatment of cells with TG attenuated H_2O_2 induced cell deaths and improved the antioxidant activity.In addition,TG regulated the apoptotic gene caspase-3,caspase-9 and anti-apoptotic gene Bcl-2.Bcl-XL during H_2O_2 induced oxidative stress in H9c2 cells.These results were comparable with quercetin treatment.For evident,flow cytometer results also confirmed the TG significantly reduced the H_2O_2 induced necrosis and apoptosis in H9c2 cells.However,further increment of TG concentration against H_2O_2 could induce the necrosis and apoptosis along with H_2O_2.Conclusions:It is suggested that less than 125μM of TG could protect the cells from H_2O_2 induced cell damage by down regulating the caspases and up regulating the Bcl-2 and Bcl-XL expression.Therefore,we suggest the trigonelline could be useful for treatment of oxidative stress mediated cardiovascular diseases in future. | Soundharrajan Ilavenil Da Hye Kim Young-Il Jeong Mariadhas Valan Arasu Mayakrishnan Vijayakumar Ponnuraj Nagendra Prabhu Srisesharam Srigopalram Ki Choon Choi | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，4： | 6 |

| 13 | A Computational Study of Thrust Vectoring Control Using Dual Throat Nozzle显示文摘Dual throat nozzle (DTN) is fast becoming a popular technique for thrust vectoring. The DTN is designed with two throats, an upstream minimum and a downstream minimum at the nozzle exit, with a cavity in between the upstream throat and exit. In the present study, a computational work has been carried out to analyze the performance of a dual throat nozzle at various mass flow rates of secondary flow and nozzle pressure ratios (NPR). Two-dimensional, steady, compressible Navier-Stokes equations were solved using a fully implicit finite volume scheme. The present computational results were validated with available experimental data. Based on the present results, the control effectiveness of thrust-vectoring is discussed in terms of the thrust coefficient and the coefficient of discharge. | Choon Sik Shin Heuy Dong Kim Toshiaki Setoguchi Shigeru Matsuo | 2010 | Journal of Thermal Science2010，19，6： | 6 |
| 14 | Expanding the scope of application of user innovation theorydA case study of the civil-military integration project in China显示文摘The focus of scholars studying user innovation has been restricted to the interaction between companies and individual users,and how companies can unilaterally exploit values from the value chain between companies and users.We argue that the value chain between the user and manufacturer should be a bilateral value chain in which both the user and manufacturer can conduct their own innovations and provide greater value to the whole value chain.In this paper,using examples from China's civil-military integration project,we took a step forward to apply the user innovation theory in the explanation of inter-sector technological value transfer.The main theoretical contribution of this paper is the expansion of the scope of application of the user innovation theory to inter-sector level research.Studying cases from China's civil-military integration project,we found that the concepts of user and innovator become blurred when we study the phenomenon across time.When we go beyond individual user and manufacturer and shift the focus of our discussion to the level of inter-sector technological value transfer,we will find that it is possible for organizational agents at large to be both users and innovators of technology. | Jhony Choon Yeong Ng Karen Kai Wen Song Qingmei Tan | 2018 | International Journal of Innovation Studies2018，2，1： | 6 |
| 15 | Heterostructures in two-dimensional colloidal metal chalcogenides:Synthetic fundamentals and applications显示文摘As a new class of two-dimensional materials, two-dimensional (2D) heterostructures constructed from metal chalcogenides (MCs) have been gaining tremendous attention due to their unprecedented physical and chemical phenomena, mainly originated from their distinct structural features such as composition, architecture type, spatial arrangement of each component, crystal structure, exposed facet and interface, dimensionality in their heterostructures. Towards the realization of practical applications, synthetic approaches need a rational design with a variety of architecture types including laterally-combined, vertically-aligned, and conformally-coated 2D MC heterostructures. Among various synthetic routes, solution-based synthesis is thought of as an alternative to fabrication through high-cost setups since it can control those structural features in a cheap fashion. This review presents recent progress on solution-based synthesis to produce various 2D MC heterostructures with a focus on the synthetic fundamentals in terms of thermodynamic and kinetic aspects related to the growth mechanism. Four different synthetic approaches are reviewed: seeded growth, cation exchange reaction, colloidal atomic layer deposition, direct synthesis including one-step process and modified electrochemical method. We also provide some representative applications of 2D MC heterostructures and their hybrid composites in various fields including optoelectronics, thermoelectrics, catalysis, and battery. Finally, we offer an insight into challenges and future directions in a synthetic improvement of 2D MC heterostructures. | Yuho Min Eunmi Im Geon-Tae Hwang Jong-Woo Kim Cheol-Woo Ahn Jong-Jin Choi Byung-Dong Hahn Joon-Hwan Choi Woon-Ha Yoon Dong-Soo Park Dong Choon Hyun Geon Dae Moon | 2019 | Nano Research2019，12，8： | 6 |
| 16 | Hepatobiliary scintigraphy for detecting biliary strictures after living donor liver transplantation显示文摘AIM:To investigate the diagnostic accuracy of hepatobiliary scintigraphy(HBS) in detecting biliary strictures in living donor liver transplantation(LDLT) patients.METHODS:We retrospectively reviewed 104 adult LDLT recipients of the right hepatic lobe with duct-toduct anastomosis,who underwent HBS and cholangiography.The HBS results were categorized as normal,parenchymal dysfunction,biliary obstruction,or bile leakage without re-interpretation.The presence of biliary strictures was determined by percutaneous cholangiography or endoscopic retrograde cholangiopancreatography(ERCP).RESULTS:In 89 patients with biliary strictures,HBS showed biliary obstruction in 50 and no obstruction in 39,for a sensitivity of 56.2%.Of 15 patients with no biliary strictures,HBS showed no obstruction in 11,for a specificity of 73.3%.The positive predictive value(PPV) was 92.6%(50/54) and the negative predictive value(NPV) was 22%(11/50).We also analyzed the diagnostic accuracy of the change in bile duct size.The sensitivity,NPV,specificity,and PPV were 65.2%,27.9%,80% and 95%,respectively.CONCLUSION:The absence of biliary obstruction on HBS is not reliable.Thus,when post-LDLT biliary strictures are suspected,early ERCP may be considered. | Yu Jin Kim Kyu Taek Lee Young Cheol Jo Kwang Hyuck Lee Jong Kyun Lee Jae-Won Joh Choon Hyuck David Kwon | 2011 | World Journal of Gastroenterology2011，17，21： | 6 |
| 17 | Potential risk factors for nonalcoholic steatohepatitis related to pancreatic secretions following pancreaticoduodenectomy显示文摘AIM: To identify risk factors for nonalcoholic steatohepatitis following pancreaticoduodenectomy, with a focus on factors related to pancreatic secretions. METHODS: The medical records of 228 patients who had a pancreaticoduodenectomy over a 16-mo period were reviewed retrospectively. The 193 patients who did not have fatty liver disease preoperatively were included in the final analysis. Hepatic steatosis was diagnosed using the differences between splenic and hepatic attenuation and liver-to-spleen attenuation as measured by non-enhanced computed tomography. RESULTS: Fifteen patients (7.8%) who showed postoperative hepatic fatty changes were assigned to Group A, and the remaining patients were assigned to Group B. Patient demographics, preoperative laboratory findings (including levels of C-peptide, glucagon, insulin and glucose tolerance test results), operation types, and final pathological findings did not differ significantly between the two groups; however, the frequency of pancreatic fistula (P = 0.020) and the method of pancreatic duct stenting (P = 0.005) showed significant differences between the groups. A multivari- ate analysis identified pancreatic fistula (HR = 3.332, P = 0.037) and external pancreatic duct stenting (HR = 4.530, P = 0.017) as independent risk factors for the development of postoperative steatohepatitis. CONCLUSION: Pancreatic fistula and external pancreatic duct stenting were identified as independent risk factors for the development of steatohepatitis following pancreaticoduodenectomy. | Sun Choon Song Seong Ho Choi Dong Wook Choi Jin Seok Heo Woo Seok Kim Min Jung Kim | 2011 | World Journal of Gastroenterology2011，17，32： | 5 |

| 19 | s Early-onset in Major Depression a Predictor of Specific Clinical Features with More Impaired Social Function?显示文摘Background: Early-onset major depressive disorder (MDD) (EOD) is often particularly malignant due to its special clinical features, accompanying impaired social function, protracted recovery time, and frequent recurrence. This study aimed to observe the effects of age onset on clinical characteristics and social function in MDD patients in Asia. Methods: In total, 547 out-patients aged 18-5 years who were from 13 study sites in five Asian countries were included. These patients had MDD diagnose according to the Diagnostic and Statistical Manual of Mental Disorders, 4^th Edition criteria. Clinical features and social function were assessed using Symptom Checklist-90-revised (SCL-90-R) and Sheehan Disability Scale (SDS). Quality of life was assessed by a 36-item Short-form Health Survey (SF-36). Analyses were performed using a continuous or dichotomous (cut-off: 30 years) age-of-onset indicator. Results: Early-onset MDD (EOD, 〈30 years) was associated with longer illness (P - 0.003), unmarried status (P 〈 0.001), higher neuroticism (P 〈 0.002) based on the SCL-90-R, and more limited social function and mental health (P = 0.006, P = 0.007) based on the SF-36 and SDS. The impairment of social function and clinical severity were more prominent at in-patients with younger onset ages. Special clinical features and more impaired social function and quality of life were associated with EOD, as in western studies. Conclusions: EOD often follows higher levels of neuroticism. Age of onset of MDD may be a predictor of clinical features and impaired social function, allowing earlier diagnosis and treatment. | Yan-Hong Liu Lin Chen Yun-Ai Su Yi-Ru Fang Manit Srisurapanont Jin Pyo Hong Ahmad Hatim Hong Choon Chua Dianne Bautista Tian-Mei Si | 2015 | Chinese Medical Journal2015，，6： | 5 |
| 20 | Single hepatocellular carcinoma ≤ 3 cm in left lateral segment:Liver resection or radiofrequency ablation?显示文摘AIM:To evaluate the long-term results of radiofrequency ablation(RFA)compared to left lateral sectionectomy(LLS)in patients with Child-Pugh class A disease for the treatment of single and small hepatocellular carcinoma(HCC)in the left lateral segments.METHODS:We retrospectively reviewed the data of133 patients with single HCC(≤3 cm)in their left lateral segments who underwent curative LLS(n=66)or RFA(n=67)between 2006 and 2010.RESULTS:The median follow-up period was 33.5mo in the LLS group and 29 mo in the RFA group(P=0.060).Most patients had hepatitis B virus-related HCC.The hospital stay was longer in the LLS group than in the RFA group(8 d vs 2 d,P<0.001).The 1-,2-,and 3-year disease-free survival and overall survival rates were 80.0%,68.2%,and 60.0%,and 95.4%,92.3%,and 92.3%,respectively,for the LLS group;and 80.8%,59.9%,and 39.6%,and 98.2%,92.0%,and 74.4%,respectively,for the RFA group.The disease-free survival curve and overall survival curve were higher in the LLS group than in the RFA group(P=0.012 and P=0.013,respectively).Increased PIVKA-Ⅱlevels and small tumor size were associated with HCC recurrence in multivariate analysis.CONCLUSION:Liver resection is suitable for single HCC≤3 cm in the left lateral segments. | Jong Man Kim Tae Wook Kang Choon Hyuck David Kwon Jae-Won Joh Justin Sangwook Ko Jae Berm Park Hyunchul Rhim Joon Hyeok Lee Sung Joo Kim Seung Woon Paik | 2014 | World Journal of Gastroenterology2014，20，14： | 4 |
