Mingqi Ye,Wirawan Dony Dahana,Chris Baumann,Sotaro Katsumata 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

This study investigates how zapping behavior is affected by television-viewing motives, classified into two broad categories: goal-directed instrumental motives and process-oriented ritualistic motives. We examine how such an impact varies among individuals with different degrees of advertising skepticism, opinion leadership, ongoing search, program involvement, and advertising involvement. By combining the television-viewing information of 1,162 individuals from April 2017 to March 2018 with survey data, we empirically analyze the effect of motivation on viewers’ zapping likelihood. The results suggest that zapping probability is lower when television-viewing is driven by instrumental motives than by ritualistic motives. The negative impact of instrumental motivations is more evident for individuals with higher ongoing search tendencies. By contrast, individuals who are more skeptical toward advertisements, have higher opinion leadership, or have higher program involvement are less vulnerable to such viewing motivations. We discuss the implications of these findings for devising an effective advertisement placement strategy.

Mingqi Guo,Li Jiang,Qingbo Yang,Chang Sun,Jianli Liu,Weidong Gao 한국의류학회 2020 Fashion and Textiles Vol.7 No.1

In order to prevent light-colored clothes from being stained by dyes released from dark clothes during the washing process, some new-type washing machines have developed the dye transfer inhibition washing program. However, there is no certified reference materials for the test of dye transfer inhibition function. To this end, cotton fabric and reactive dyes are used as experimental materials to prepare standardized samples to evaluate the dye transfer inhibition function of washing machines. Firstly, the single factor analysis method is used to analyze the significance of the dyeing parameters including dye dosage, dyeing temperature, sodium sulfate dosage and sodium carbonate dosage. Secondly, a 4-factor 5-level experimental design and theoretical prediction of the best dyeing parameters are successively carried out through central composite design and response surface method. Two evaluation indicators, the dye release amount of the standardized sample of dyed fabric and the color difference value of the standardized sample of white fabric after washing, are proposed as the response values for response surface analysis to search the optimal dying parameters in theory. The optimal dyeing parameters obtained through response surface analysis are that the dosage of dye is 5.63% (owf), the dyeing temperature is 60 °C, the dosage of sodium sulfate is 93.60 g/L, and the dosage of sodium carbonate is 15 g/L. Experimental results indicate that the standardized samples prepared with optimal dyeing parameters can effectively distinguish the dye transfer inhibition function of washing machines.

Mingqi Zhou,Lizhuang Ma,Bing Sheng (사)한국CDE학회 2013 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8

Music can always bring out infinite reverie. Famous music website like last.fm further tags music based on raised emotions, from sadness to joy. Color on the other hand, is believed to have a connection with human emotions. This paper proposes a music visualization system Muvis that digs out emotion from music which is represented by color from a revised HSV color model and the mapping process adopt a simplified linear probability density function to fit emotion’s Gaussian distribution. After that, we use three dimensions of space to display the music with particle system in a visually meaningful way. By making use of both low level features, such as intensity, and high level features such as emotion, Muvis can give user a better understanding of the music content. Examples are presented for music with different emotion and user studies are shown our method can create enjoyable result and enhance emotional resonance at the same time.

Influence of K2TiF6 in electrolyte on characteristics of the microarc oxidation coating on aluminum alloy

Mingqi Tang,Weiping Li,Huicong Liu,Liqun Zhu 한국물리학회 2012 Current Applied Physics Vol.12 No.5

Black and gray microarc oxidation (MAO) coatings were prepared in a phosphate electrolyte with and without K2TiF6 on 2A70 aluminum alloy, respectively. Voltageetime curves were recorded during the MAO process. The effects of K2TiF6 on the morphology, composition, abrasive resistance and corrosion resistance of MAO coatings were investigated. The results showed that the MAO coating produced in the electrolyte with K2TiF6 was thicker, and more uniform than that produced in the electrolyte without K2TiF6. Ti was detected in the surface of the MAO coating formed in the electrolyte with K2TiF6. The results of abrasive resistance and corrosion resistance showed that the MAO coating formed in the electrolyte with K2TiF6 exhibited better abrasive resistance and corrosion resistance.

The Candidate Tumor Suppressor Gene SLC8A2 Inhibits Invasion, Angiogenesis and Growth of Glioblastoma

Mingqi Qu,Ju Yu,Hongyuan Liu,Ying Ren,Chunxiao Ma,Xingyao Bu,Qing Lan 한국분자세포생물학회 2017 Molecules and cells Vol.40 No.10

Glioblastoma is the most frequent and most ag-gressive brain tumor in adults. Solute carrier family 8 member 2 (SLC8A2) is only expressed in normal brain, but not present in other human normal tissues or in gliomas. Therefore, we hy-pothesized that SLC8A2 might be a glioma tumor suppressor gene and detected the role of SLC8A2 in glioblastoma and explored the underlying molecular mechanism. The glioblas-toma U87MG cells stably transfected with the lentivirus plasmid containg SLC8A2 (U87MG-SLC8A2) and negative control (U87MG-NC) were constructed. In the present study, we found that the tumorigenicity of U87MG in nude mice was totally inhibited by SLC8A2. Overexpression of SLC8A2 had no effect on cell proliferation or cell cycle, but impaired the invasion and migration of U87MG cells, most likely through inactivating the extracellular signal-related kinases (ERK)1/2 signaling pathway, inhibiting the nuclear translocation and DNA binding activity of nuclear factor kappa B (NF-κB), reducing the level of matrix metalloproteinases (MMPs) and urokinase-type plasminogen activator (uPA)-its receptor (uPAR) system (ERK1/2-NF-κB-MMPs/uPA-uPAR), and altering the protein levels of epithelial to mesenchymal transitions (EMT)-associated proteins E-cardherin, vimentin and Snail. In addition, SLC8A2 inhibited the angiogenesis of U87MG cells, probably through combined inhibition of endothelium-dependent and endothelium-nondependent angiogenesis (vascular mimicry pattern). Totally, SLC8A2 serves as a tumor suppressor gene and inhibits invasion, angiogenesis and growth of glioblastoma.

Immobilized Bioactive Agents onto Polyurethane Surface with Heparin and Phosphorylcholine Group

Mingqi Tan,Yakai Feng,Heyun Wang,Li Zhang,Musammir Khan,Jintang Guo,Qingliang Chen,Jianshi Liu 한국고분자학회 2013 Macromolecular Research Vol.21 No.5

Heparin (HEP) and phosphorylcholine groups (PC) were grafted onto the polyurethane (PU) surface in order to improve biocompatibility and anticoagulant activity. After the surface grafting sites of PU were amplified with the primary amine groups of polyethylenimine (PEI), heparin was covalently linked onto the surface by the reaction between the amino group and the carboxyl group. PC groups were covalently immobilized on the PU-PEI surface through the reaction between the amino group and the aldehyde group of phosphorylcholine glyceraldehyde (PCGA). The surface density of primary amine groups was determined by a ninhydrin assay. The amino group density reached a maximum of 0.88 μmol/cm2 upon incorporation of 10 wt% PEI. The amount of heparin covalently immobilized on the PU-PEI surface was determined by the toluidine blue method. The grafting chemistry resulted in the comparatively dense immobilization of HEP (2.6 μg/cm2) and PC to the PU-PEI surfaces. The HEP and PC modified surfaces were characterized by water uptake (PU 0.15 mg/cm2, PU-PEI 3.54 mg/cm2, PU-HEP 2.04 mg/cm2, PU-PC 2.38 mg/cm2), water contact angle (PU 95.3º, PU-PEI 34.0º, PU-HEP 39.5º, PU-PC 37.2º), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectroscopy (XPS),atomic force microscopy (AFM), and scanning electron microscope (SEM). The results demonstrated that the PUPEI surface was successfully grafted with HEP and PC. The hydrophilicity and hemocompatibility of these grafted surfaces were significantly improved. These results suggested that the PU-HEP and PU-PC composite films are promising candidates for blood contacting tissue engineering.

Xu Mingqi 서울대학교 경제연구소 2010 Seoul journal of economics Vol.23 No.1

On 22 January 2010, the Chinese State Statistical Bureau announced that the 2009 Chinese economic growth rate remained at 8.7 percent, which fulfilled the 8 percent target preset by the central government at the end of 2008. Many celebrated this achievement, attributing the stimulated economy to government economic policy. This paper analyzes how the macroeconomic policy of the Chinese government contributed to economic growth even under the global financial crisis. The present effects of this policy and its implications on the future are also examined.

Aggregation Behavior of Aqueous Solutions of 1-Dodecyl-3-methylimidazolium Salts with Different Halide Anions

Ao, Mingqi,Kim, Doseok American Chemical Society 2013 Journal of chemical and engineering data Vol.58 No.6

<P>The interfacial and bulk properties of the aqueous solutions of imidazolium-based ionic liquids with different halide anions ([C<SUB>12</SUB>mim]Cl, [C<SUB>12</SUB>mim]Br, [C<SUB>12</SUB>mim]I) were investigated by surface tension and electrical conductivity measurements. The lowest surface tension (γ<SUB>cmc</SUB>) and maximum surface excess concentration (Γ<SUB>max</SUB>) values from the surface tension measurements showed that [C<SUB>12</SUB>mim]I had the highest surface activity. The thermodynamic pontentials of micellization (Δ<I>G</I><SUP>0</SUP><SUB>m</SUB>, Δ<I>H</I><SUP>0</SUP><SUB>m</SUB>, Δ<I>S</I><SUP>0</SUP><SUB>m</SUB>) indicated that the micellization of [C<SUB>12</SUB>mim]Cl and [C<SUB>12</SUB>mim]Br was entropy-driven, while that of [C<SUB>12</SUB>mim]I was enthalpy-driven at 15 °C but entropy-driven above 20 °C. This distinct behavior for [C<SUB>12</SUB>mim]I was thought to be due to the higher binding affinity of I<SUP>–</SUP> to the micellar interface.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jceaax/2013/jceaax.2013.58.issue-6/je301147k/production/images/medium/je-2012-01147k_0003.gif'></P>
