Zhi Guo,Hongjiang Liu,Jianchu Zheng,Liugen Chen,Haiyan Yuan 한국작물학회 2015 Journal of crop science and biotechnology Vol.18 No.2

Insect-proof nets (IPN) are widely used to protect crops from invertebrate pests. The effects of IPN on the main microclimate parameters of paddy fields, as well as grain quality, were investigated for three japonica Oryza sativa L. varieties (Nanjing 44, Nanjing 45, and Suxiangjing 3) that are widely grown in China. The environmental temperature of IPN-treated fields increased slightly, whereas the maximum value of photosynthetically active radiation (PAR), daily cumulative PAR, and daily cumulative global radiation all decreased. However, the ratio of PAR to global radiation increased significantly, from 15.08 to 45.48%. Compared to the no insect-proof net (NIPN) treatment, the head rice percentage increased significantly for all three varieties; however, the chalky grain percentage, area and degree, and the amylose content all decreased significantly. The response of gel consistency, protein concentration, and the main parameters of the rapid visco analyzer (RVA) profile of rice starch to IPN treatment differed between varieties. The peak viscosity and breakdown were increased compared to the NIPN treatment, whereas the final viscosity and setback were decreased. However, no significant differences were found between the IPN and NIPN treatments. Furthermore, statistical analysis indicated no interaction between rice planting pattern (RPP) and rice variety (RV) for the rice grain quality parameters. These results suggest that IPN treatment improved rice grain quality for all japonica rice varieties studied, possibly due to the slight increase in environmental temperature and increased ratio of PAR to global radiation in IPN treated paddy fields.

作为政治秩序原理的正义与仁义 : 亚里士多德与孟子之间的一种互诠

陈治国 ( Chen¸ Zhi-guo ) 한국유교학회 2014 유교사상문화연구 Vol.56 No.-

“正义”和“仁义”在亚里士多德和孟子那里分别构成了优秀政治社会秩序的基本原理, 同时也被看作政治共同体成员所应培养的与他人相关的总体德性或伦理德性整体。这在某种程度上表明, 两位哲学家都把城邦政治的首要功能限定于主要促进每一个体伦理德性的实现或发展以及优秀公民人格的培养, 因为这更多地涉及一个人类存在者的本性和福祉。不过, 在伦理德性的形成路径上, 亚里士多德主张要由伦理德性公民的、政治的向度推进到人性向度、道德向度, 孟子则更倾向于一种相反的培养程序。并且, 二者虽然都为哲学家或者圣贤在正义城邦或仁义之治发展中的恰当角色提供了两种选项, 即政治顾问和伦理教师, 但是, 真正支撑着这两种角色的深层理由并不完全一致。 “Justice” in Aristotle and “benevolence and appropriateness” (renyi) in Mencius are individually conceived as the primary principle of an excellent social-political order in their ethical and political thought. In a sense, this shows that, both philosophers mainly define primary function of the politics of city or state as promoting the actualization or development of personal ethical virtue and the cultivation of excellent citizens. At the same time, Each of these two concepts is regarded as the whole of virtues with relation to others or the totally ethical virtues which should be cultivated by all the members of one political community. As the shaping path of ethical virtue is concerned, Aristotle holds that, we should attain the good character by advancing to human and moral dimension from civil and political one, but Mencius seems to give the priority to the former than the latter. Besides, both thinkers provide two roles, which are political consultant and ethical teacher, for philosophers or sages in the development of just city or government of benevolence and appropriateness, however, profound reasons that sustain these roles are not very consistent.

Zhiguo Xia,Peng Du,Libing Liao,Guowu Li,Shuai Jin 한국물리학회 2010 Current Applied Physics Vol.10 No.4

Eu2+ and Mn2+ co-doped calcium aluminate silicate chloride phosphors with the chemical composition of Ca3Al2Si2O8Cl4:Eu2+, Mn2+ have been prepared by a solid-state method, and their luminescence properties have been investigated by tuning the En2+/Mn2+ ions concentration. The phase formation and microstructure of Ca3Al2Si2O8Cl4:Eu2+, Mn2+ phosphors have been illuminated by XRD and SEM analysis. Photoluminescence (PL) spectrum reveals that Ca3Al2Si2O8Cl4:Eu2+ exhibits a strong blue emission band centered at 431 nm, while Ca3Al2Si2O8Cl4:Eu2+, Mn2+ can emit bluish-white light by adjusting the Mn2+ content appropriately. The energy transfer mechanism involving Eu2+–Mn2+ have also been investigated.

Preparation, Characterization and Photocatalytic Activity of Sodium Humate/Nano-TiO2 Coating on Glass Spheres for Flue Gas Denitrification

Zhiguo Sun,Jitao Yang,Li Zhang,Hongyong Xie 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.6

A new photocatalyst of sodium humate (HA–Na)/Nano-TiO2 coating on the glass spheres for flue gas denitrification (DeNOx) was prepared using the impregnation method. The HA–Na/TiO2 is characterized by Brunauer–Emmett–Teller (BET), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). The photocatalytic activity of HA–Na/TiO2 on removing NOx was investigated in a self-designed photocatalytic reactor. The synergistic mechanism of HA–Na and TiO2 on DeNOx is also proposed and demonstrated. The experimental results indicate that specific surface area and average pore size of HA–Na are improved owing to the mixed TiO2 nanoparticles. The crystal structure of TiO2 has little change after mixing with HA–Na. Due to high photocatalytic performance of TiO2, NO was oxidized to NO2 and HNO3 eventually. On the other hand, HA–Na support can absorb and react with HNO3, which accelerates 10% of the catalytic reaction of TiO2 and the utilization of light source. The chemical and physiological activity of oxidized HA–Na are improved than the original humate. The HA–Na/TiO2 photocatalysts show great property on eliminating NOx because of the promoting effect between HA–Na and TiO2, and the NO removal efficiency can reach to 80% at the optimum condition.

Zhiguo Zhang,Chengping Zhang,Kangming Jiang,Zhiwei Wang,Yunjuan Jiang,Qihua Zhao,Minghao Lu 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.6

Existing analytical method to predict tunneling-induced pile deformation is generally based on the Winkler foundation model that neglects shear effects of soil, which is not sufficient for engineering practice. A simplified solution based on Kerr foundation model is presented in this study to investigate the tunnel-soil-pile interaction. In order to improve the accuracy of the prediction for tunneling-induced free-field movements, the cavity contraction theory is utilized in the first stage which received a higher accuracy than the previous solution. In the second stage, the soil free-field displacement is imposed on the existing pile, and the simplified solution for pile deformation governed by the disturbance of passive displacement is established based on the Kerr foundation model, which can take account of the soil shear effects. The applicability and accuracy of the simplified solution are then verified by several cases including the reported analytical solution, centrifuge modeling tests and observed data in situ. Good agreements are obtained in the comparative analyses, which demonstrates that the proposed solution can serve as an alternative approach for conservatively estimating tunneling-induced pile deformation in the preliminary design in clay. Furthermore, the parametric analysis associated with the pile deformation has also been performed. As a result, it is of primarily theoretical and practical significance to investigate the influence of soil shear effects on the tunnel-soil-pile interaction mechanics.

Massive MIMO Channel Estimation Algorithm Based on Weighted Compressed Sensing

Zhiguo Lv,Weijing Wang 한국정보처리학회 2021 Journal of information processing systems Vol.17 No.6

Compressed sensing-based matching pursuit algorithms can estimate the sparse channel of massive multiple input multiple-output systems with short pilot sequences. Although they have the advantages of low computational complexity and low pilot overhead, their accuracy remains insufficient. Simply multiplying the weight value and the estimated channel obtained in different iterations can only improve the accuracy of channel estimation under conditions of low signal-to-noise ratio (SNR), whereas it degrades accuracy under conditions of high SNR. To address this issue, an improved weighted matching pursuit algorithm is proposed, which obtains a suitable weight value uop by training the channel data. The step of the weight value increasing with successive iterations is calculated according to the sparsity of the channel and uop. Adjusting the weight value adaptively over the iterations can further improve the accuracy of estimation. The results of simulationsconducted to evaluate the proposed algorithm show that it exhibits improved performance in terms of accuracy compared to previous methods under conditions of both high and low SNR.

SaaS application mashup based on High Speed Message Processing

Zhiguo Chen,Myoungjin Kim,Yun Cui 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.5

Diversified SaaS applications allow users more choices to use, according to their own preferences. However, the diversification of SaaS applications also makes it impossible for users to choose the best one. Furthermore, users can't take advantage of the functionality between SaaS applications. In this paper, we propose a platform that provides an SaaS mashup service, by extracting interoperable service functions from SaaS-based applications that independent vendors deploy and supporting a customized service recommendation function through log data binding in the cloud environment. The proposed SaaS mashup service platform consists of a SaaS aggregation framework and a log data binding framework. Each framework was concreted by using Apache Kafka and rule matrix-based recommendation techniques. We present the theoretical basis of implementing the high-performance message-processing function using Kafka. The SaaS mashup service platform, which provides a new type of mashup service by linking SaaS functions based on the above technology described, allows users to combine the required service functions freely and access the results of a rich service-utilization experience, using the SaaS mashup function. The platform developed through SaaS mashup service technology research will enable various flexible SaaS services, expected to contribute to the development of the smart-contents industry and the open market.
