瓷器는 중국 고대의 독창적인 예술의 한 분야 이며 고대인들의 생활수준을 한 단계 업그레이드 시켰을 뿐만 아니라 중국 전통 手工業의 발전을 보여주는 지표이다. 瓷器業은 지속적인 발전을 하였고 宋代에 이르러 한 단계 더 발전을 하였으며 定窯系, 鈞窯系, 磁州窯 등의 窯系가 등장하게 되었다. 定州曲陽을 중심으로한 定窯瓷器는 定窯系를 代表하였고 당시 瓷器製造業이 최고의 수준이었음을 보여준다. 북송시기에 定窯가 성행하였던 주요 이유는 세 가지가 있다. 첫째, 定州에는 자기업이 발전하는데 필요한 원료가 풍부하였다. 둘째, 하북의 邢窯의 영향을 받아 靑銅器鑄造 기술과 邢州窯의 工藝 技術을 바탕으로 하여 覆燒法과 印花, 刻花를 주로 하는 새로운 공예 기술을 창조하였다. 셋째, 唐宋社會變革의 시기에 고대 귀족들이 몰락을 하고 金銀器, 靑銅器 등이 시장에서 퇴출당하고 瓷器가 民間에서 日用品으로 사용되게 되었다. 北宋 末年에 이르러 定瓷를 중심으로 하는 北方b陶瓷器業은 衰落을 하였는데 수많은 원인이 있지만 戰爭으로 인한 쇠락이 가장 큰 원인이고 대량으로 瓷器를 생산 하게 되면서 자기의 원료가 부족하게 되었고 模造品이 시장에 등장하면서 이로 인해 窯瓷器 시장이 위축되게 되었다. 이외에도 北宋後期에 宋 徽宗時期에 통치자들 사이에서 靑器를 많이 사용하였고 白瓷를 중심으로 하는 定瓷는 高級 瓷器 시장에서 퇴출되게 되었다. 定窯系를 중심으로 한 宋代 北方 窯系는 중국 고대 瓷器史에서 南方의 瓷窯와 北方의 金元瓷器業에 큰 영향을 끼쳤으며 다른 나라의 瓷器業에도 많은 영향을 주었다. There are mainly three reasons why Ding kiln reached its heyday in Northern song dynasty: first, Ding kiln had the abound porcelain which were needed in the development of porcelain industry; second, because of the influence of Hebei Xing kiln, as well as on the basis of local bronze casting technology and Xing Zhou kiln craft technology, it made innovation the “inverse burning” as well as new craft like printing and engraved designs; three, it adapted to the social change of Tang Dynasty and Song Dynasty, after the fall of ancient aristocratic, golden ware, silver ware and bronze ware exited the mainstream market, china became the main commodity of common people, and it suitable for the social needs. But in the end of Northern song dynasty, North china ceramics whose representative is Ding kiln declined gradually. There were many reasons, but the destruction of the war was the most direct factor, while the large quantities of porcelain production caused the exhaustion and shortage of porcelain clay resources and fuel,; at the same time, many similar products of the generic competition compressed the market of Ding kiln; In addition, the ruling circle whose head was Emperor Huizong of Song was favor of Qing porcelain, Ding kiln which mainly produced White porcelain retreated from the top grade of china ceramic market. However, the North ceramics whose representative is Ding kiln in Song Dynasty had an important influence in ancient Chinese porcelain history, which mainly reflected in its influence to the South ceramics and the North Jin Yuan devices.

A note on end properties of Marcinkiewicz Integral

Yong Ding 대한수학회 2005 대한수학회지 Vol.42 No.5

In this note we give the mapping properties of the Marcinkiewicz integral $\mu_\Omega$ at some end spaces.~More precisely, we first prove that $\mu_\Omega$ is a bounded operator from $H^{1,\infty}(\Bbb R^n)$ to $L^{1,\infty}$ $(\Bbb R^n)$.~As a corollary of the results above, we obtain again the weak type (1,1) boundedness of $\mu_\Omega,$ but the condition assumed on $\Omega$ is weaker than Stein's condition.~Finally, we show that $\mu_\Omega$ is bounded from BMO$(\Bbb R^n)$ to BMO$(\Bbb R^n)$.~The results in this note are the extensions of the results obtained by Lee and Rim recently.

Ding, Yong,Li, Xiao-Rong,Yang, Kai-Yan,Huang, Li-Hua,Hu, Gui,Gao, Kai Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

Effects of the Epstein-Barr virus (EBV) on cellular protein expression are essential for viral pathogenesis. To characterize the cellular response to EBV infection, differential proteomes of gastric epithelial AGS cells were analyzed with two-dimensional gel electrophoresis (2-DE) followed by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) and liquid chromatography electrospray/ionization ion trap (LC-ESI-IT) mass spectrometry identification. Mass spectrometry identified 9 altered cellular proteins, including 5 up-regulated and 4 down-regulated proteins after EBV infection. Notably 2-DE analysis revealed that EBV infection induced increased expression of heat shock cognate 71 kDa protein, actin cytoplasmic 1, pyridoxine-5'-phosphate oxidase, caspase 9, and t-complex protein 1 subunit alpha. In addition, EBV infection considerably suppressed those cellular proteins of zinc finger protein 2, cyclin-dependent kinase 2, macrophage-capping protein, and growth/differentiation factor 11. Furthermore, the differential expressional levels of partial proteins (cyclin-dependent kinase 2 and caspase 9) were confirmed by Western blot analysis.Thus, this work effectively provided useful protein-related information to facilitate further investigation of the mechanisms underlying EBV infection and pathogenesis.

YONG DING,SONGYUAN DAI,Litao Jia,YANMEI MA,ZHAOQIAN LI,CHANGNENG ZHANG,JIANXI YAO,LIE MO,LINHUA HU,BING ZHANG,LING JIANG 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2014 NANO Vol.9 No.5

The sub-microspheres play multiple roles in enhancing dye adsorption and light-scattering toimprove the performance of dye-sensitized solar cells (DSSCs). In this work, the well-de¯ned TiO 2sub-microspheres with anatase granular-like nanocrystals are prepared in high yield by com-bining hydrolytic process with solvothermal treatment. Scanning electron microscopy (SEM) andtransmission electron microscopy (TEM) results indicated that plenty of rhombic nanoparticleswith ? 18 nm diameter having mutual contacts to neighboring nanoparticles were densely self-assembled into sub-microspheres, and abundant mesopores existed in the whole sub-microsphereswith superior light scattering ability. The appropriate pore diameter and relatively high speci¯csurface area of the as-obtained sub-microsphere result in a higher dye adsorption. As expected, byusing the sub-microspheres as a scattering layer, a higher photovoltaic conversion e±ciency of10.15% is obtained for DSSCs.

Experimental study on ultimate torsional strength of PC composite box-girder with corrugated steel webs under pure torsion

Ding, Yong,Jiang, Kebin,Shao, Fei,Deng, Anzhong Techno-Press 2013 Structural Engineering and Mechanics, An Int'l Jou Vol.46 No.4

To have a better understanding of the torsional mechanism and influencing factors of PC composite box-girder with corrugated steel webs, ultimate torsional strength of four specimens under pure torsion were analyzed with Model Test Method. Monotonic pure torsion acts on specimens by eccentric concentrated loading. The experimental results show that cracks form at an angle of $45^{\circ}$ to the member's longitudinal axis in the top and bottom concrete slabs. Longitudinal reinforcement located in the center of cross section contributes little to torsional capacity of the specimens. Torsional rigidity is proportional to shape parameter ${\eta}$ of corrugation and there is an increase in yielding torque and ultimate torque of specimens as the thickness of corrugated steel webs increases.

Structural identification based on incomplete measurements with iterative Kalman filter

Yong Ding,Lina Guo 국제구조공학회 2016 Structural Engineering and Mechanics, An Int'l Jou Vol.59 No.6

Structural parameter evaluation and external force estimation are two important parts of structural health monitoring. But the structural parameter identification with limited input information is still a challenging problem. A new simultaneous identification method in time domain is proposed in this study to identify the structural parameters and evaluate the external force. Each sampling point in the time history of external force is taken as the unknowns in force evaluation. To reduce the number of unknowns for force evaluation the time domain measurements are divided into several windows. In each time window the structural excitation is decomposed by orthogonal polynomials. The time-variant excitation can be represented approximately by the linear combination of these orthogonal bases. Structural parameters and the coefficients of decomposition are added to the state variable to be identified. The extended Kalman filter (EKF) is augmented and selected as the mathematical tool for the implementation of state variable evaluation. The proposed method is validated numerically with simulation studies of a time-invariant linear structure, a hysteretic nonlinear structure and a time-variant linear shear frame, respectively. Results from the simulation studies indicate that the proposed method is capable of identifying the dynamic load and structural parameters fairly accurately. This method could also identify the time-variant and nonlinear structural parameter even with contaminated incomplete measurement.

ON THE NORM OF THE OPERATOR aI + bH ON L^p(ℝ)

Ding, Yong,Grafakos, Loukas,Zhu, Kai Korean Mathematical Society 2018 대한수학회보 Vol.55 No.4

We provide a direct proof of the following theorem of Kalton, Hollenbeck, and Verbitsky [7]: let H be the Hilbert transform and let a, b be real constants. Then for 1 < p < ${\infty}$ the norm of the operator aI + bH from $L^p(\mathbb{R})$ to $L^p(\mathbb{R})$ is equal to $$\({\max_{x{\in}{\mathbb{R}}}}{\frac{{\mid}ax-b+(bx+a){\tan}{\frac{\pi}{2p}}{\mid}^p+{\mid}ax-b-(bx+a){\tan}{\frac{\pi}{2p}}{\mid}^p}{{\mid}x+{\tan}{\frac{\pi}{2p}}{\mid}^p+{\mid}x-{\tan}{\frac{\pi}{2p}}{\mid}^p}}\)^{\frac{1}{p}}$$. Our proof avoids passing through the analogous result for the conjugate function on the circle, as in [7], and is given directly on the line. We also provide new approximate extremals for aI + bH in the case p > 2.

On the norm of the operator $aI+bH$ on $L^p(\mathbb R)$

Yong Ding,Loukas Grafakos,Kai Zhu 대한수학회 2018 대한수학회보 Vol.55 No.4

We provide a direct proof of the following theorem of Kalton, Hollenbeck, and Verbitsky \cite{HKV}: let $H$ be the Hilbert transform and let $a,b$ be real constants. Then for $1<p<\infty$ the norm of the operator $aI+bH$ from $L^p(\mathbb R)$ to $L^p(\mathbb R)$ is equal to $$ \bigg(\max_{x\in \mathbb R}\frac{|ax-b+(bx+a)\tan \frac{\pi}{2p}|^p+|ax-b-(bx+a)\tan \frac{\pi}{2p}|^p}{|x+\tan \frac{\pi}{2p}|^p+|x-\tan \frac{\pi}{2p}|^p} \bigg)^{\frac 1p}. $$ Our proof avoids passing through the analogous result for the conjugate function on the circle, as in \cite{HKV}, and is given directly on the line. We also provide new approximate extremals for $aI+bH$ in the case $p>2$.

Polymorphism, Expression of Natural Resistance-associated Macrophage Protein 1 Encoding Gene (NRAMP1) and Its Association with Immune Traits in Pigs

Ding, Xiaoling,Zhang, Xiaodong,Yang, Yong,Ding, Yueyun,Xue, Weiwei,Meng, Yun,Zhu, Weihua,Yin, Zongjun Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.8

Natural resistance-associated macrophage protein 1 encoding gene (NRAMP1) plays an important role in immune response against intracellular pathogens. To evaluate the effects of NRAMP1 gene on immune capacity in pigs, tissue expression of NRAMP1 mRNA was observed by real time quantitative polymerase chain reaction (PCR), and the results revealed NRAMP1 expressed widely in nine tissues. One single nucleotide polymorphism (SNP) (ENSSSCG00000025058: g.130 C>T) in exon1 and one SNP (ENSSSCG00000025058: g.657 A>G) in intron1 region of porcine NRAMP1 gene were demonstrated by DNA sequencing and PCR-RFLP analysis. A further analysis of SNP genotypes associated with immune traits including contain of white blood cell (WBC), granulocyte, lymphocyte, monocyte (MO), rate of cytotoxin in monocyte (MC) and $CD4^-CD8^+$ T lymphocyte subpopulations in blood was carried out in four pig populations including Large White and three Chinese indigenous breeds (Wannan Black, Huai pig and Wei pig). The results showed that the SNP (ENSSSCG00000025058: g.130 C>T) was significantly associated with level of WBC % (p = 0.031), MO% (p = 0.024), MC% (p = 0.013) and $CD4^-CD8^+$ T lymphocyte (p = 0.023). The other SNP (ENSSSCG00000025058: g.657 A>G) was significantly associated with the level of MO% (p = 0.012), MC% (p = 0.019) and $CD4^-CD8^+$ T lymphocyte (p = 0.037). These results indicate that the NRAMP1 gene can be regarded as a molecular marker for genetic selection of disease susceptibility in pig breeding.
