A user interface design of the health QR code system in China
Qiming Zhu,Young-Hwan Pan 한국융합학회 2021 한국융합학회논문지 Vol.12 No.1
팬데믹 시대를 맞아 코로나 등의 질병 예방과 통제에도 스마트 의료 기술을 응용하게 되었고, 중국의 스마트 의료 기술을 대표하는 개인 의료 QR 코드 시스템도 편리성과 안전성에 있어 개선되어야 할 문제점이 대두되었다. 즉, 현행 중국의 개인 의료 QR 코드 시스템은 그 종류가 많고 각각 독립적으로 존재하여 스마트 취약 계층의 사용자에게 큰 불편을 초래하고 있으며, 동시에 수집된 개인정보 보호와 처리의 문제도 제기되고 있다. 본 논문에서는 이러한 문제 를 개선하기 위하여 개인 의료 QR 코드 시스템의 통합과 개인정보 보호 과정을 투명화할 것을 제안하고, 사용자의 편리를 위한 인터페이스를 설계하였다. 본 논문에서 제시한 방법과 새롭게 디자인한 인터페이스를 통해 사용자는 더욱 편리하고 안전하게 스마트 의료 시스템을 누릴 수 있으며 광범위하게 확산될 우려가 있는 질병의 예방과 통제에도 유 효한 성과를 보장할 수 있다. In the pandemic era, smart medical technology has also been applied to prevent and control diseases such as COVID-19. Health QR code system shave sparked recent discussion in the hopes of improving its convenience and safety. The many types of current health QR code systems in China exists causes inconvenience to those that are vulnerable, as well as raising the issue of personal information protection. In order to solve this problem, this paper proposes transparent integration of the health QR code systems and the process of protecting personal information, as well as designs an interface for user convenience. Through the method presented in this paper and the newly designed interface, users can enjoy the smart pharmaceutical system more conveniently and safely, and ensure effective results in the prevention and control of diseases that are likely to spread.
Reliability Evaluation of Key Hydraulic Components for Actuators of FAST Based on Small Sample Test
Ming Zhu,Jingyi Zhao,Qiming Wang 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.11
The five-hundred meter aperture spherical radio telescope (FAST) is China’s major science and technology infrastructure project. Upon completion, this telescope will be considered the largest single-dish radio telescope in the world. As main active mechanism of FAST, 2225 hydraulic actuators are used for adjusting the reflectors. The reliability of hydraulic actuators is the most critical matter. This paper applies the reliability theory and reliability test method into large project for the first time. Firstly, a parallel energy-saving method and equipment to test the two components of the actuators for FAST are designed. Secondly, reliability model based on small sample test is used to perform the best linear unbiased estimation of the test data. Average impact lifetime of the sampled gear pump and the sampled relief valve in their working condition are calculated. Finally, the results show that the lifetime request of the sampled gear pump and the sampled relief valve for hydraulic actuator of FAST are satisfied. The research method has guiding significance to the reliability study of key hydraulic components for similar hydraulic systems.

Plant Bowman-Birk type bran trypsin inhibitors(BBTI) belong to a family of serine protease inhibitors thatinhibit trypsin activity and play roles in plant developmentand defense responses to both biotic and abiotic stresses. Inthis study, transgenic rice plants overexpressing BBTI4 (OXBBTI4)were generated. Reverse-transcription polymerasechain reaction and western blot (WB) analysis demonstratedthat the BBTI4 mRNA and protein levels were significantlyincreased in OX-BBTI4. Notably, two BBTI4 protein formswith different molecular weight (18 kD and 28 kD) wererevealed by WB analysis. In non-transgenic plants, BBTI4-28kD and BBTI4-18kD were mainly expressed in roots andleaves, respectively, while in transgenic OX-BBTI4 plants,both protein forms were expressed constitutively. Subcellularanalysis revealed that BBTI4 is localized in the cytosol. Moreover, Xanthomonas oryzae pv. oryzae (Xoo) inoculationexperiments demonstrated that transgenic OX-BBTI4 riceplants conferred partial but broad-spectrum Xoo resistance. InOX-BBTI4 transgenic rice plants, the expression of OsPR3 andOsPR10a proteins was induced and gradually increased afterXoo infection, while the expression of OsPR1a, OsPR1b andOsPR-pha remained unchanged. Taken together, these resultssuggest that BBTI4 may play a role in rice resistance to Xoo,and OsPR3 and OsPR10a may be involved in the OX-BBTI4-dependent partial Xoo resistance response.

Catalytic performance of various acids in the coupling reaction of formaldehyde and methyl formate to produce methyl glycolate and methyl methoxy acetate has been studied. The influence of reaction conditions, such as catalyst amount, reaction temperature, reaction time, and molar ratio of formaldehyde to methyl formate, has also been investigated. The results showed that the acid strength had great influence on the reaction, namely, stronger acds had higher activities. It was also found that the reaction temperature and time had significant effect on the reaction, and the preferable conditions were quite different as different acids were used.
