Research and practice on system engineering management of a mobile payment project

Yongkai ZHOU, Hongfeng CHAI

Frontiers of Engineering Management 2017, Volume 4, Issue 2,   Pages 127-137 doi: 10.15302/J-FEM-2017011

Abstract: The popularization of the mobile internet has given rise to demand for flexible and convenient payment methods. For China, it is necessary to keep pace with or even lead the trend of innovation and development in the age of mobile payment. From the perspective of systems engineering, this paper introduces research and implementation of China UnionPay’s mobile payment project. The general requirements and core engineering problems of the mobile payment project are summarized based on analyses of the characteristics and engineering difficulties of this project. Integration of innovative technologies is introduced to resolve the contradiction between ease-of-use and security. A rapid iterative development process is adopted to improve the product release efficiency as well as the users' experience. The launch of the mobile payment project also opens the window to coordinating and upgrading the whole payment industry chains.

What have we known so far for fluorescence staining and quantification of microplastics: A tutorial review

Shengdong Liu, Enxiang Shang , Jingnan Liu , Yining Wang , Nanthi Bolan , M.B. Kirkham , Yang Li

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1,   Pages 8-8 doi: 10.1007/s11783-021-1442-2

Abstract: Understanding the fate and toxicity of microplastics (MPs,<5 mm plastic particles) is limited by quantification methods. This paper summarizes the methods in use and presents new ones. First, sampling and pretreatment processes of MPs, including sample collection, digestion, density separation, and quality control are reviewed. Then the promising and convenient staining procedures and quantification methods for MPs using fluorescence dyes are reviewed. The factors that influence the staining of MPs, including their physicochemical properties, are summarized to provide an optimal operation procedure. In general, the digestion step is crucial to eliminate natural organic matter (NOM) to avoid interference in quantification. Chloroform was reported to be the most appropriate solvent, and 10–20 μg/mL are recommended as optimal dye concentrations. In addition, a heating and cooling procedure is recommended to maintain the fluorescence intensity of MPs for two months. After staining, a fluorescence microscope is usually used to characterize the morphology, mass, or number of MPs, but compositional analysis cannot be determined with it. These fluorescence staining methods have been implemented to study MP abundance, transport, and toxicity and have been combined with other chemical characterization techniques, such as Fourier transform infrared spectroscopy and Raman spectroscopy. More studies are needed to focus on the synthesis of novel dyes to avoid NOM’s interference. They need to be combined with other spectroscopic techniques to characterize plastic composition and to develop image-analysis methods. The stability of stained MPs needs to be improved.

Theory and Practice of Maritime Power

Wang Fang

Strategic Study of CAE 2016, Volume 18, Issue 2,   Pages 55-60 doi: 10.15302/J-SSCAE-2016.02.006

Abstract:

By discussing the importance of martime power in the overall narrative of the Chinese socialism, this paper explores the potent connotations of creating and wielding such power in this new era. This study outlines the foundations of a theoretical system of harmonious maritime power that will be made a reality to support the development of China and the common interests of all human beings, which should be operated in consultation with other nations on a dialectical level. Futhermore, it also argues that China should adopt a new model of peaceful marine development, adhere to the basic principles of mutual benefit and win-win cooperation, implement the strategic task of enforcing the country and enriching the people through ocean development, as well as promote the overall development of the oceanic economy, marine science and technology, marine environment and maritime forces. Finally, this paper introduces the idea of transforming China into a new maritime power that is "strong, but not tyrannical", which require a new approach to maritime power development with Chinese characteristics featuring mutual benefits and sustainable development.
