本研究では、期待確信モデル(ECM)を理論的背景として、オンラインショッピングに関するレコメンデーションシステムの継続利用意向の形成メカニズムを明らかにした。第一部分では有用性の知覚に対する外生変数(功利的動機と快楽的動機)の関係を確認した。第二部分では、有用性の知覚がユーザーの認知的、情緒的満足度に及ぼす影響を検証した。有用性の知覚は認知的満足度と情緒的満足度、およびユーザーの継続利用意向に強い正の影響を与えることが明らかとなった。 This study, grounded in the Expectation Confirmation Model (ECM), elucidated the formation mechanism of the continued intention to use recommendation systems for online shopping. In the first part, we examined the relationship between external variables (utilitarian motivation and hedonic motivation) and the perceived usefulness. In the second part, we verified the impact of the perceived usefulness on users' cognitive and emotional satisfaction. It was found that the perception of usefulness has a strong positive influence on cognitive satisfaction, emotional satisfaction, and users' continued intention to use.

Maiping Yang,WeiQu Liu,Liyan Liang,Chi Jiang,Yankun Xie,Hongyi Shi,Fengyuan Zhang,Ke Pi 한국섬유공학회 2020 Fibers and polymers Vol.21 No.8
In this paper, various fabrics with good self-cleaning performance were prepared via a facile dip-coating method. The fabrics composed with different fibers and woven techniques were firstly immersed in ZnO sol to increase the surfaceroughness, then dip-coated in fluoroalkylsilane (HFT) solution to reduce the surface energy. The coated fabric showedexcellent superhydrophobicity with a water contact angle (WCA) of 157.8 o and water shedding angle (WSA) of 5 o. Themorphologies and chemical compositions of prepared fabrics were observed with SEM, XPS and EDS. The obtained fabrickept stable water-repelling property in acidic and alkaline solutions, solvents and UV irradiation. Benefited from its high antiwaterability and photocatalysis function of ZnO, the coated fabric demonstrated excellent self-cleaning performance. Thisversatile approach of constructing superhydrophobic fabrics is attractive and could be large-scaled employed in industrialproduction process.

Hydrophobic Waterborne Epoxy Coating Modified by Low Concentrations of Fluorinated Reactive Modifier
Hongyi Shi,Weiqu Liu,Maiping Yang,Xinsheng Liu,Yankun Xie,Zhengfang Wang 한국고분자학회 2019 Macromolecular Research Vol.27 No.4
Fluorinated (meth) acrylate oligomer modified epoxy resin (PHFBMA-DGEBA) and polyether-modified epoxy resin (MPEG-DGEBA) were successfully synthesized and used as reactive modifier and emulsifier for epoxy resins, respectively. GPC, FTIR and 1H NMR were employed to verify the synthesis. The influence of both the concentration and the molecular weight of PHFBMA-DGEBA on the properties of waterborne epoxy resin coatings was investigated. Surface energy and surface composition were probed by contact angle measurements and X-ray photoelectron spectroscopy (XPS), which strongly confirmed the enrichment of fluorinate atoms on the surface. The surface energy of waterborne epoxy coating was decreased from 44.46 mN/m to 23.20 mN/m by adding just 0.09 wt% PHFBMADGEBA- 2, indicating its high effectiveness in improving the surface hydrophobicity. Moreover, the physical properties of waterborne epoxy coatings prepared with different concentration and molecular weight of fluorinated reactive modifier, such as water absorption, Shore D hardness, adhesion, thermal properties and optical transmittance, were also analyzed in detail. Taken together, the waterborne epoxy coatings prepared with low concentrations of reactive modifier are economical and have great potential in large scale industry applications.

Rapid Screen of IL-5/IL-5Rα Blocking Antibodies in the HEK293-IL-5Rα-CSF2RB Transfected Cell Line
Shijie Li,Fei Han,Chang Liu,Weiyan Dai,Wenfeng Ke,Yongqi Chen,Eric Fordjour,Yankun Yang,Zhonghu Bai 한국생물공학회 2023 Biotechnology and Bioprocess Engineering Vol.28 No.4
Interleukin-5 (IL-5) binding to interleukin-5 receptor subunit alpha (IL-5Rα) increases the number of eosinophils and enhances eosinophil activity. This leads to eosinophil tissue infiltration and damage to the lungs, ultimately resulting in exacerbation of asthma. Antibodies that block IL-5 binding to IL-5Rα are thought to play an important role in advanced asthma. Currently, key methods used to screen for targeted drugs are Surface Plasmon Resonance which is costly and anti-proliferation assays which are tedious and have a low signal-to-noise ratio. Here we describe a Fluorescence Activated Cell Sorting (FACS) assay, based on human embryonic kidney (HEK)- 293 cells with stable expression of IL-5Rα and the cytokine receptor common subunit beta (CSF2RB). Cells co-expressing IL-5Rα and CSF2RB had a 16% increase in the ability to bind IL-5 compared to cells expressing only IL-5Rα. The optimal concentration of IL-5 for the FACS assay was 0.1 μg/mL. The established FACS was used to screen anti IL-5 nanobodies and hybridoma supernatants for candidate antibodies that block the IL-5/IL-5α interaction. When compared to anti-proliferation assays, this method saved up to 90% of the assay time, offering the advantage of rapidity and accuracy in vitro. The assay described here provides a novel approach for rapid screening of IL-5/IL- 5Rα blocking antibodies in vitro to accelerate the development of drugs for asthma.
