Yan Meng,Kerry Johnson,Brian Simms,Matthew Conforth 보안공학연구지원센터 2008 International Journal of Hybrid Information Techno Vol.1 No.1

Increasingly, innovations in miniaturization and embedded systems are making pervasive computing a reality. Meanwhile, similar advancements in robotics have made autonomous mobile robots easier to develop and more cost-efficient. However, since the field of ubiquitous robotics remains relatively unexplored, we develop SMARbot (Stevens Modular Autonomous Robot), as a tool to explore the pervasive capability of miniature robots. The SMARTBot was designed to be a highly modular, adaptable, inexpensive base model to integrate miniature mobile robots into the pervasive computing environment. The hardware and software architecture of the prototype are proposed. The experimental results demonstrate the feasibility and efficiency of the SMARbot in the real-world scenarios

Meng, Fa-Yan,Jiang, Bing-Li,Lin, Cui-Wu,Wang, Li,Tan, Xiao-He Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.3

Two new benzimidazolyl-containing complexes have been synthesized by reactions of $Cu^{II}$ salts and 1,2-bis(benzimidazolyl) benzene ($H_2bbbz$) with two different dicarboxylate ligands. When phthalate acid ($H_2pt$) was employed as secondary ligand, a 0D molecular complex Cu$(H_2bbbz)(pt){\cdot}(H_2pt)$ (1)was furnished and when the secondary ligand was instead by a linear bridging ligand of terephthalic acid ($H_2tp$) a 1D zipper-like coordination polymer $[Cu(H_2bbbz)(tp){\cdot}2(C_2H_5OH){\cdot}H_2O]_n$ (2) was obtained, suggesting the structure-direction effect of the secondary dicarbxylate ligand. The preliminary investigation on the spectral properties of the complexes was also presented.

Meng, Fa-Yan,Yu, Sheng-Rong,Liang, Li-Xi,Zhong, Xue-Ping,Wang, Li,Zhu, Jin-Mei,Lin, Cui-Wu Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.7

The self-assembly of one novel organic complex based on chlorogenic acid (HCA) and 2,2'-bipyridine (2,2'-bipy) has been synthesized and characterized. The complex achieved by hydrogen-bonding interactions, adopted a 1:1 stoichiometry in a solid state. The proton transfer occurred from the carboxyl oxygen to the aromatic nitrogen atom to form salts CA${\cdot}$(2,2'-Hbipy), the 2,2'-Hbipy molecule individually occupies the pseudo-tetragonum that is formed with CA. In this paper, the interactions of CA${\cdot}$(2,2'-Hbipy) with bovine serum albumin (BSA) were studied by fluorescence spectrometry. For CA${\cdot}$(2,2'-Hbipy), HCA and 2,2'-bipy, the average quenching constants for BSA were $2.4384{\times}10^4$, $4.653{\times}10^3$, and $3.059{\times}10^3\;L{\cdot}mol^{-1}$, respectively. The mechanism for protein fluorescence quenching is apparently governed by a static quenching process. The Stern-Volmer quenching constants and corresponding thermodynamic parameters ${\Delta}$H, ${\Delta}$G and ${\Delta}$S were calculated. The binding constants and the number of binding sites were also investigated. The conformational changes of BSA were observed from synchronous fluorescence spectra.

Yanli Yu,Yanjiao Li,Fengjuan Jia,Meng Zhao,Wencai Li,Qi Sun,Nana Li,Wenlan Li,Zhaodong Meng 한국식물학회 2017 Journal of Plant Biology Vol.60 No.6

FK506-binding proteins (FKBPs), which belongto the peptidyl-prolyl cis/trans isomerase superfamily, areinvolved in plant response to abiotic stresses. A number ofFKBP family genes have been isolated in plants, but littlehas been reported of FKBP genes in maize. In this study, adrought-induced FKBP gene, ZmFKBP20-1, was isolated frommaize and was characterized for its role in stress responsesusing gene expression, protein subcellular localization,transformation in Arabidopsis, expression patterns of thestress-responsive genes, and physiological parameter analysis. During drought and salt stresses, ZmFKBP20-1 transgenicArabidopsis plants exhibited enhanced tolerance, which wasconcomitant with the altered expression of stress/ABAresponsivegenes, such as COR15a, COR47, ERD10, RD22,KIN1, ABI1, and ABI2. The resistance characteristics ofZmFKBP20-1 overexpression were associated with a significantincrease in survival rate. These results suggested thatZmFKBP20-1 plays a positive role in drought and salt stressresponses in Arabidopsis and provided new insights into themechanisms of FKBP in response to abiotic stresses inplants.

Meng Yan,Hao Wang,Rui Wei,Wenwen Li 대한약학회 2024 Archives of Pharmacal Research Vol.47 No.3

Arsenical medicine has obtained its status in traditional Chinese medicine for more than 2,000 years. In the 1970s, arsenictrioxide was identifi ed to have high effi cacy and potency for the treatment of acute promyelocytic leukemia, which promotedmany studies on the therapeutic eff ects of arsenic trioxide. Currently, arsenic trioxide is widely used to treat acutepromyelocytic leukemia and various solid tumors through various mechanisms of action in clinical practice; however, it isaccompanied by a series of adverse reactions, especially cardiac toxicity. This review presents a comprehensive overviewof arsenic trioxide from preclinical and clinical effi cacy, potential mechanisms of action, toxicities, and rescue strategies fortoxicities to provide guidance or assistance for the clinical application of arsenic trioxide.

Yan-Chun Meng 연세대학교 동서문제연구원 2000 Global economic review Vol.29 No.4

In order to cater to the globalization trend, a general governmental institution reform has taken place in the world, and the aim of the reform is to limit governmental power and promote governmental efficiency. The force of the reform comes from both the domestic press and oversea press. On a national level, the request for legality of governmental power and controllability of governmental decision-making is becoming more urgent on a daily basis. On an international level, globalization has urged cooperation and raped response from every countries in the world. Most countries focus on limiting governmental power and power dispersion.

哲學 : 大慧宗고的看話禪體系

염맹상 ( Meng Xiang Yan ) 한국중국학회 2004 國際中國學硏究 Vol.7 No.-

Kan Hua Zen is the typical model of Zen Buddhism after the Song Dynasty. Its system had been perfected by Da Hui who lived in Song Dynasty. The system may be summarized as follows: Ideological preparation before enter Zen meditation. The preparation includes two aspects: one is encouraging the faith; the other is knowing the theories of Buddhism well. Encouraging the faith is to encourage the pupils to practice the doctrine. Knowing the theories of Buddhism well is mainly to obtain the thinking method of Zen Buddhism. In Da Hui`s option, both are the needs to enter Zen meditation. Particularly it is the foundation of the mental operation that holds Buddhism theories when one is entering the meditation of Zen. The relationship between meditation of Kan Hua(meditate Hua Tou) and Buddhism theories. Kan Hua is a method to practice Mahayana. What Hua Tou represents is the core of the Mahayana theories-the thought of noumenon. The Hua Tou(a sentence said by a Zen teacher) used by Zong Gao included "Cypress seeds in court", "To drink off the west river`s water in one mouthful", "A dog does not own Buddhata" etc. What every one of these Hua Tou expresses is noumenon. According to Mahayana theories, all the worlds are mental states. And so the key of practice moral teachings is to carry out the reversal of the consciousness. To meditate Hua Tau is a method to carry out the reversal of the consciousness. It is a perfect procedure to combine the process of the preparation of mind to Kan Hua in detail and evolution of psychology. The thought of awakening Self-cultivation. The thought of awakening self-cultivation is expressed in the sentence of "the self-will is free and unfettered". It is to protect the mental state of awakening that "the self-will is free and unfettered". Its basic direction is not arbitrary but clearing up sticking to something. Da Hui raised the awakening self-cultivation to the height matching the essence, making the mental activity connected with essence actively, To explain the awakening self-cultivation in the Mahayana`s inwardness theory, he made Ka Hua Zen theory perfect.

Minjia Meng,Yonghai Feng,Weisheng Guan,Yan Liu,Yanfang Xi,Yongsheng Yan 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.6

Highly effective molecularly imprinted nano-polymer on wollastonite (nano-WMIP) was prepared byimprinting technique using oil-in-water emulsion polymerization in the presence of salicylic acid (SA) astemplate. The adsorption behavior of nano-WMIP including adsorption kinetic, isotherms, selectiveadsorption, recognition, and effects of initial pH, ionic strength, initial concentration, adsorptiontemperature, and amount of adsorbents were investigated in detail. Moreover, the selective recognitionof nano-WMIP was further investigated by HPLC toward analogs of SA. The relative selectivitycoefficients for p-HB, MS, and MP were 113.4, 8.049, and 6.239, respectively, showing that much higherselectivity of SA on nano-WMIP was obtained than that of wollastonite-based non-imprinted polymer(nano-WNIP).
