( Yan Hua Zhu ),( Sehoon Park ),( Suk Jung Jeong ) 국제지역학회 2014 국제지역연구 Vol.18 No.1

The Korean economy has accomplished the high rates of economic growth during the last four decades through the export-led growth strategy by the government. It is well recognized that the export in the Korean manufacturing industries has been still leading the Korean economic growth. On the other hand the Chinese economy has also achieved rapidly economic growth since 1990`s. The cyclicality of productivity has been one of the essential issues in economics. Since Solow(1957) developed the dominant approach to the measurement of productivity growth, Solow`s approach, which assumes the perfect competition, the constant returns to scale, and the full use of input factor has been modified particularly in Hall`s(1990) and Basu`s(1996) works. This paper establishes the empirical model based on Hall`s and Basu`s models, estimates 4 types of Solow`s residuals in 8 Korean manufacturing industries and in Chinese economy and analyzes the cyclicality of measured productivity, comparing the productivities in both countries.

Stabilization of Switched Systems with Uncontrollable Subsystems

Yanli Zhu,Yuangong Sun 한국전산응용수학회 2013 Journal of applied mathematics & informatics Vol.31 No.5

In this paper, we study the stabilization problem of switched systems with both controllable and uncontrollable subsystems. By using an average dwell time approach, we first establish a sufficient condition such that the switched system is exponentially stabilizable under appropriate switching signals. We also extend this result to the switched system with nonlinear impulse effects and disturbances. Numerical examples are given to illustrate the theoretical results.

Component-based model for posttensioned steel connections against progressive collapse

Yan Fei Zhu,Chang Hong Chen,Ying Huang,Zhaohui Huang,Yao Yao,Leon M. Keer 국제구조공학회 2021 Steel and Composite Structures, An International J Vol.40 No.4

A component-based method for the estimation of the posttensioned (PT) steel frame against progressive collapse is proposed and presented in the current paper. A mechanical model of PT steel connections is developed and benchmarked with experimental data of a PT beam-column substructure from literature. The developd mechanical models of four PT connections are able to capture the initial elastic stiffness, decompression load, and residual stiffness under lateral loading. Then, analysis of a reduced-scale three-storey two-bay PT steel frame is carried out with sufficient accuracy by incorporating the proposed joint model into the frame analysis. The proposed method is then applied to assessing progressive collapse of a one-storey two-bay PT frame under middle column removal scenario, and is verified against existing experimental and ANSYS finite element results. Three resistance mechanism for progressive collapse of the PT frame are evaluated, which consists of angle flexural mechanism, beam compression arching action and strand tensile catenary action. Finally, parameter analyses of the PT frames are conducted to investigate the effects of the connection details on the behavior and resistance of progressive collapse. The proposed model can be used to predict the quasi-static behavior of PT frames under monotonic vertical loading conditions with satisfactory accuracy.

Pin1 Promoter rs2233678 and rs2233679 Polymorphisms in Cancer: A Meta-analysis

Zhu, Yan-Mei,Liu, Jing-Wei,Xu, Qian,Yuan, Yuan Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

PIN1 is one member of the parvulin PPIase family. By controlling Pro-directed phosphorylation, PIN1 plays an important role in cell transformation and oncogenesis. There are many polymorphisms in the PIN1 gene, including rs2233678 and rs2233679 affecting the PIN1 promoter. Recently, a number of case-control studies were conducted to investigate the association between PIN1 gene rs2233678 and rs2233679 polymorphism and cancer risk. However, published data are still conflicting. In this paper, we summarized data for 5,427 cancer cases and 5,469 controls from 9 studies and attempted to assess the susceptibility of PIN1 gene polymorphism to cancers by a synthetic meta-analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the relationship. All analyses were performed using Stata software. Our results suggested that rs2233678 represented a protective factor in overall analysis (CC vs GG: OR= 0.697, 95%CI: 0.498-0.976; CG vs GG: OR=0.701, 95%CI: 0.572-0.858; Dominant model: OR= 0.707, 95%CI: 0.590-0.847; C allele vs G allele: OR=0.734, 95%CI: 0.623-0.867) and especially for squamous cell carcinoma of the head and neck, lung cancer and breast cancer in Asians and Caucasians. The rs2233679 polymorphism was significantly associated with decreased cancer risk in overall analysis (CT vs CC: OR=0.893, 95%CI=0.812-0.981; Dominant model: OR=0.893, 95%CI=0.816-0.976; T allele vs C allele; OR=0.947, 95%CI=0.896-1.000) and especially in Asians. In conclusion, our meta-analysis suggested that -842G>C (rs2233678) and -667C>T (rs2233679) may contribute to genetic susceptibility for cancer risks. Further prospective research with larger numbers of worldwide participants is warranted to draw comprehensive and firm conclusions.

Effects of Aluminum Nanoparticles on Thermal Decomposition of Ammonium Perchlorate

Zhu, Yan-Li,Huang, Hao,Ren, Hui,Jiao, Qing-Jie Korean Chemical Society 2013 대한화학회지 Vol.57 No.1

The effects of aluminum nanoparticles (AlNs) on the thermal decomposition of ammonia perchlorate (AP) were investigated by DSC, TG-DSC and DSC-TG-MS-FTIR. Addition of AlNs resulted in an increase in the temperature of the first exothermic peak of AP and a decrease in the second. The processing of non-isothermal data at various heating rates with and without AlNs was performed using Netzsch Thermokinetics. The dependence of the activation energy calculated by Friedman's isoconversional method on the conversion degree indicated the decomposition process can be divided into three steps. They were C1/D1/D1 for neat AP, determined by Multivariate Non-linear Regression, and changed to C1/D1/F2 after addition of AlNs into AP. The isothermal curves showed that the thermal stability of AP in the low temperature stage was improved in the presence of AlNs.

Legal Duties and Tortious Liability of Third-Party E-Commerce Platforms

zhu yan 한국외국어대학교 법학연구소 2017 외법논집 Vol.41 No.4

E-commerce is an important driver of the Chinese economy, with the motto “he who owns the platform owns the world” attesting to its importance. However, e-commerce platforms also pose unique legal challenges. In China, they are either third-party or self-trading, with elucidation of the former’s legal obligations and tortious liabilities being the concern of the present article. The treatment of e-commerce platforms has undergone a profound transformation in Chinese jurisprudence, with traditional counter-space rental and commission theory giving way to an independent legal status. With reference to the latest draft of the Chinese E-Commerce Law and key cases, this article offers an in-depth analysis of the legal obligations borne by third-party e-commerce platforms. These include: an ex ante duty of due diligence, duty to provide technical safeguards, promulgate fair trading rules, store information, supervise in the course of trading, protect user privacy and data, and respect the consumer’s right to be forgotten. These obligations balance the rights and interests of third-party e-commerce platforms, their users and society at large. Since e-commerce traders are able to exert a material influence on the rights and interests of users through advertisements, the reputation system and ranking, it is appropriate that they be stripped of technical neutrality in the transaction. Rather, in the event that their breach of legal obligations incurs tortious liability, it is only proper that they shoulder a commensurate burden in accordance with the principle that risk is consistent with responsibility. The ‘safe harbor’ and ‘red flag’ principles contained in Articles 36(2) and (3) of China’s Tort Liability Law are instructive in imputing liability. Although third-party e-commerce platforms are currently governed through a patchwork of laws and regulations, the Chinese National Peoples’ Congress has nevertheless resolved to draft the specialist E-Commerce Law, acknowledging the industry’s legal importance. We should remain keenly attentive of legislative efforts, and see what specific provisions concerning third-party e-commerce platforms are made in the future E-Commerce Law.

Dynamic increase factor for progressive collapse analysis of semi-rigid steel frames

Yan Fei Zhu,Chang Hong Chen,Yao Yao,Leon M. Keer,Ying Huang 국제구조공학회 2018 Steel and Composite Structures, An International J Vol.28 No.2

An empirical and efficient method is presented for calculating the dynamic increase factor to amplify the applied loads on the affected bays of a steel frame structure with semi-rigid connections. The nonlinear static alternate path analysis is used to evaluate the dynamic responses. First, the polynomial models of the extended end plate and the top and seat connection are modified, and the proposed polynomial model of the flush end plate connection shows good agreement as compared with experimental results. Next, a beam model with nonlinear spring elements and plastic hinges is utilized to incorporate the combined effect of connection flexibility and material nonlinearity. A new step-by-step analysis procedure is established to obtain quickly the dynamic increase factor based on a combination of the pushdown analysis and nonlinear dynamic analysis. Finally, the modified dynamic increase factor equation, defined as a function of the maximum ratio value of energy demand to energy capacity of an affected beam, is derived by curve fitting data points generated by the different analysis cases with different column removal scenarios and five types of semi-rigid connections.

Medical Tourism Industry in Kangwon Province and Its Economic Impacts on the Region

Yan Hua Zhu,Joo Hoon Kang,Yong-Sik Jung 한국산업정보학회 2014 한국산업정보학회논문지 Vol.19 No.3

This paper has two purposes. The first is to suggest the new and simple method to derive a regional input-output model from national input-output table published by the Bank of Korea. The interregional input-output table has not been devised in spite of its potential use while the national table has been made every five years with the revised version during each five years. Second, this paper aims to derive Kangwon interregional input-output model from the national model using the regional supply proportional of industry and to analyze the effect of medical tourism industry on the regional economy of Kangwon Province. The paper measures, in particular, the effect of medical tourism industry on the financial self-sufficiency of Kangwon Province using the estimated output elasticity of tax revenue with the autoregressive distributed lag scheme ADL(1,1) in which the dependent variable ad the single explanatory variable are each lagged once.<br/>
