Background: To analyze the mortality distribution of esophageal cancer in China from 1991 to 2012, to forecast the mortality in the future five years, and to provide evidence for prevention and treatment of esophageal cancer. Materials and Methods: Mortality data for esophageal cancer in China from 1991 to 2012 were used to describe its epidemiological characteristics, such as the change of the standardized mortality rate, urban-rural differences, sex and age differences. Trend-surface analysis was used to study the geographical distribution of the mortality. Curve estimation, time series, gray modeling, and joinpoint regression were used to predict the mortality for the next five years in the future. Results: In China, the incidence rate of esophageal cancer from 2007 and the mortality rate of esophageal cancer from 2008 increased yearly, with males at $8.72/10^5$ being higher than females, and the countryside at $15.5/10^5$ being higher than in the city. The mortality rate increased from age 45. Geographical analysis showed the mortality rate increased from southern to eastern China, and from northeast to central China. Conclusions: The incidence rate and the standardized mortality rate of esophageal cancer are rising. The regional disease control for esophageal cancer should be focused on eastern, central and northern regions China, and the key targets for prevention and treatment are rural men more than 45 years old. The mortality of esophageal cancer will rise in the next five years.

Absorption of NO from simulated flue gas by using NaClO2/(NH4)2CO3 solutions in a stirred tank reactor

Rui-Tang Guo,Wei-Guo Pan,Jian-Xing Ren,Xiao-Bo Zhang,Qiang Jin 한국화학공학회 2013 Korean Journal of Chemical Engineering Vol.30 No.1

Experiments were performed in a stirred tank reactor to study the absorption kinetics of NO into aqueous solutions of NaClO2/(NH4)2CO3 solutions. The absorption process is a fast pseudo-reaction, and the reaction was found to be second-order with respect to NO and first-order with respect to NaClO2, respectively. The frequency factor and the average activation energy of this reaction were 4.56×1011 m6/(mol2 s) and 33.01 kJ/mol respectively. The absorption rate of NO increased with increasing reaction temperature, but decreased with increasing (NH4)2CO3 solution.

Optimal Doping Level of Iron in Bismuth Titanate for Oxide Optoelectronics

Tang, Rui,Han, Jun Young,Kim, Ji Hyeon,Bark, Chung Wung American Scientific Publishers 2017 Journal of nanoscience and nanotechnology Vol.17 No.10

<P>A series of Fe-doped Lanthanum-modified Bismuth Titanate (Fe-BLT) based powders was synthesized by conventional solid reaction methods with increasing amounts of Fe atoms substituting Ti atoms. We conducted X-ray diffraction (XRD) analysis and found that all samples crystallized with an orthorhombic structure. The size distribution and morphology of the Fe-BLT samples were observed by using scanning electron microscopy (SEM). The absorption spectra of the Fe-BLT based powders obtained from ultraviolet-visible spectroscopy (UV-Vis) showed that the optical bandgap decreased from 2.42 eV to 1.93 eV as a result of the substitution of Fe atoms. The results of the XRD and SEM measurements with the UV-Vis spectra indicate that no Fe-based secondary phase contributed to the reduction of the optical bandgap. Therefore, we conclude that substitutional iron atoms are responsible for modifying the electronic structure of bismuth titanate based oxides. The optical bandgaps of the series of iron doped samples did not decrease linearly with increasing nominal Fe content in the powder. This indicates a small amount of Fe is sufficient to tune the bandgap to the requisite values. The simple alloying approach for controlling bandgap developed here could be applied to other complex oxides materials for use in emerging optoelectronic and energy applications.</P>

Tang, Rui-Ren,Gong, Nian-Hua Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.8

A simple and safe method has been presented for conversion of olefins into bromohydrins using hydrogen bromide and hydrogen peroxide as bromide source by visible light induced within a very short time to get high yield bromohydrins along with a little mount dibromo-product. In this paper, cyclohexene is firstly carried out as the model substrate and investigated the bromination under HBr/$H_2O_2$ system using 150 W incandescent light irradiated in C$Cl_4$ within short time to get good yield of 2-bromocyclohexanol along with a little mount of 1,2-dibromocyclohexane; then, a series of alkenes are brominated to corresponding bromohydrins using the same protocol.

Effect of Cu doping on the SCR activity of CeO2 catalyst prepared by citric acid method

Rui-Tang Guo,Wen-long Zhen,Wei-Guo Pan,Yue Zhou,Jie-nan Hong,Hong-jian Xu,Qiang Jin,Cheng-gang Ding,Shi-yi Guo 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4

CeO2–CuO catalyst prepared by citric acid method was investigated for selective catalytic reduction of NO with NH3. The activity of the CeO2 catalyst was enhanced about 8–27% in the temperature range of 125–225 ℃ at a space velocity of 28,000 h 1 by the addition of Cu. It was found that the state of Cu species had great impact on the SCR performance of CeO2–CuO catalyst. Cu2+ can enhance the low temperature activity of SCR reaction, while CuO would promote NH3 oxidation before SCR reaction at high temperature, which would cause the decrease of its high temperature SCR activity.

Effect of preparation methods on the performance of CeO2/Al2O3catalysts for selective catalytic reduction of NO with NH3

Rui-Tang Guo,Yue Zhou,Wei-Guo Pan,Jie-nan Hong,Wen-long Zhen,Qiang Jin,Cheng-gang Ding,Shi-yi Guo 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.6

CeO2/Al2O3 catalysts prepared by three methods were investigated for selective reduction of NO with NH3. It was found that the catalyst prepared by the single step sol–gel method had the best SCR activity and SO2 resistance performance. From the results of BET, XRD, TPD and TPR, it can be concluded that large surface area, strong interaction, highly dispersed nano-crystalline ceria, high NH3 adsorption capacity and good redox ability might be the main reasons for the excellent performance of CeO2/Al2O3catalyst prepared by the single step sol–gel method.

Joint Mode Selection and Resource Allocation for Mobile Relay-Aided Device-to-Device Communication

( Rui Tang ),( Jihong Zhao ),( Hua Qu ),( Zhengcang Zhu ),( Yanpeng Zhang ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.3

Device-to-Device (D2D) communication underlaying cellular networks is a promising add-on component for future radio communication systems. It provides more access opportunities for local device pairs and enhances system throughput (ST), especially when mobile relays (MR) are further enabled to facilitate D2D links when the channel condition of their desired links is unfavorable. However, mutual interference is inevitable due to spectral reuse, and moreover, selecting a suitable transmission mode to benefit the correlated resource allocation (RA) is another difficult problem. We aim to optimize ST of the hybrid system via joint consideration of mode selection (MS) and RA, which includes admission control (AC), power control (PC), channel assignment (CA) and relay selection (RS). However, the original problem is generally NP-hard; therefore, we decompose it into two parts where a hierarchical structure exists: (i) PC is mode-dependent, but its optimality can be perfectly addressed for any given mode with additional AC design to achieve individual quality-of-service requirements. (ii) Based on that optimality, the joint design of MS, CA and RS can be viewed from the graph perspective and transferred into the maximum weighted independent set problem, which is then approximated by our greedy algorithm in polynomial-time. Thanks to the numerical results, we elucidate the efficacy of our mechanism and observe a resulting gain in MR-aided D2D communication.

Synthesis and Luminescence Properties of Lanthanide Complexes of a Novel Polyaminopolycarboxylate Ligand

Tang, Chang-Quan,Tang, Rui-Ren,Tang, Chun-Hua,Zeng, Zhi-Wen Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.5

A novel polyaminopolycarboxylate ligand with many coordination sites, N,N,$N^1,N^1,N^2,N^2$-[( 2,4,6-tri(aminomethyl)-pyridine]hexakis(acetic acid) (TPHA), was designed and synthesized and its lanthanide complexes $Na_6Tb_2$(TPHA)$Cl_6{\cdot}14H_2O$, $Na_6Eu_2$(TPHA)$Cl_6{\cdot}8H_2O$, $Na_6Gd_2$(TPHA)$Cl_6{\cdot}11H_2O$ and $Na_6Sm_2$(TPHA)$Cl_6{\cdot}9H_2O$ were successfully prepared. The ligand and the complexes were characterized by elemental analysis, IR, mass, NMR and TG-DTA. The TG-DTA studies indicated that the complexes had a high thermal stability, whose initial decomposition temperature was over $270^{\circ}C$. The luminescence properties of the complexes in solid state were investigated and the results suggested that $Tb^{3+}$ and $Eu^{3+}$ ions could be sensitized efficiently by the ligand, especially the Tb(III) complex displayed a very strong luminescence intensity (> 10000) and only displayed characteristic metal-centered luminescence. Also, the correlative comparison between the structure of ligand and luminescence properties showed how the number of the coordination atoms of ligand can be a prominent factor in the effectiveness of ligand-to-metal energy transfer.

중국 애니메이션 산업과 정책 연구

탕뢰(Tang Rui),김일태(Kim Il Tae) 한국만화애니메이션학회 2009 만화애니메이션연구 Vol.- No.15

현재 중국은 융성했던 애니메이션의 전통을 부활할 수 있으며, 중국 고유의 특색을 살리는 애니메이션을 제작하는 원대한 계획을 앞당겨 실현할 수 있다. 중국은 이미 텔레비전 문화가 널리 보급되고 있는 상황이며 대량의 외국 애니메이션이 중국시장에 진입하고 있다. 이러한 현대 중국의 애니메이션 상황 속에서 중국 애니메이션 산업이 선진국의 대열로 들어서는데 문제점이 되는 여러 사항들에 대해 애니메이션과 관련한 정책, 문화, 시장, 신업 등의 네 가지 측면을 중국 근현대의 시대 순으로 나누어 분석하였고 특히 중국 애니메이션 산업을 발전시키기 위하여 한국의 우수한 사례를 함께 제고하고 그 해결 방안을 찾고자 하였다. 연구 결과 중국 애니메이션 발전을 위해 국외와의 합작을 강화하면서 국제시장과 연결하고 적용하여 중국의 제작실력과 수준을 향상시킴과 동시에 중국 정부의 문화산업 및 애니메이션 산업, 교육 전반에 대한 실질적인 지원 정책이 실시되어야 한다는 결론을 내리게 되었다. Today, China can reestablish its previously prosperous Chinese animation tradition and can make a great plan of recreating earlier characteristic Chinese animation style. In China, TV culture was already here to stay and a large number of foreign countries' animations were entering the Chinese market. Presently, Chinese animation was recognized as time order of 4points: Animation policy, Animation industry, Animation market, and culture. My studies about these issues show the Chinese animation industry has entered an advancing country. I have especially researched into solving these issues with the Korean and Chinese animation & market. As result, I have concluded that the Chinese animation industry must engage itself in foreign animation styles and global market in order to further advance its industry. To help raise its production quality & technique status, I recommend the Chinese government actually give the donations promised to the Chinese animation and culture industries as well as the education system now.
