Zhu Gao-feng

Frontiers of Engineering Management 2014, Volume 1, Issue 1,   Pages 105-112 doi: 10.15302/J-FEM-2014010

Abstract: Since China's drive in 1978 to implement national reforms and open it up to the outside world,its higher education sectorhas made rapid progressin the field of engineering and has been able to achieverapid expansion of scale,Positive change in educational structure,more education investment, improved teaching quality, Educational reform and international cooperation. While praising the achievements,we need toacknowledgethat there are also some problems in China's engineering education, asimbalancebetweensupplyanddemand,homogeneity of goals and patterns, Lack of practice,curriculum system not aligned with the characteristics of engineering,insufficient importance attached to innovation and entrepreneurial education, Poor competence mix.In light of China's process of modernization and the Outline, we forecast that:competition between universities will intensify and the supply-demand imbalance will be alleviated, differentiation depends on the reform of engineer system and administrative university classification,quality of engineering education will be improved with a complete quality assurance system,industrial transformation will be conducive to joint talent development by universities and businesses,instructors will be the mainstay of educational reform,quality of students should be improved in many different ways. As China's modernization accelerates, the quality of its engineering education is getting better and better. We expect to work closely with foreign colleagues to improve the quality to turn out engineering talents meeting the demand of national development.

Current situation and challenge of registry in China

Yang Zhang,Yuji Feng,Zhi Qu,Yali Qi,Siyan Zhan

Frontiers of Medicine 2014, Volume 8, Issue 3,   Pages 294-299 doi: 10.1007/s11684-014-0355-x

Abstract:

Increasing emphasis has been placed on registries for an organized system used in developing clinical research to improve health care. China has sufficient data that can be applied broadly, but the heterogeneity and irregularity of registries limit their applicability. This article aims to describe the status of registries in China and the related challenges. Patient registries for observational studies were retrieved from the International Clinical Trials Registry to quantitatively evaluate the number of comparatively high-quality registries in China. A literature search was also performed to provide support and updates. A total of 64 patient registries were retrieved from ClinicalTrials.gov using disease, product, and health service as criteria. The sample sizes ranged from 15 to 30 400, with only 12 registries marked as completed. This article describes and compares the detailed information in many aspects. The efficient use of registries has already made considerable progress in China; however, registries still require standardization, high-quality transition, and coordinated development.

Impact of renewable energies on the operation and economic situation of coal fired power stations: Actualsituation of coal fired power stations in Germany

Hans-Joachim KRAUTZ, Alexander LISK, Joachim POSSELT, Christian KATZER

Frontiers in Energy 2017, Volume 11, Issue 2,   Pages 119-125 doi: 10.1007/s11708-017-0468-4

Abstract: Due to the fluctuating character of the renewable energy sources the demand of conventional power plants for flexibility is increasing. In the recent years, in Germany there has been a fast rise of production capacity of renewable energies, especially from wind turbines, photovoltaic installations, and biomass plants. The installed nominal power of wind turbines is actually (December 2016) 42 GW and of photovoltaic installations 40?GW. The renewable electric energy production in Germany is about 190?TWh/a, which represents a share of 33% of the yearly demand. The increased need for flexibility affects both the power gradients as well as the minimum load of conventional power plants. Due to this flexibility behaviour, conventional power plants are faced with problems concerning the durability of power plant components, corrosion, more maintenance effort and consequently the overall life expectancy. Another consequence of the increasing share of renewable energies is the decreasing full load operating hours, especially of coal fired and gas power plants. Along with decreasing revenues from the energy exchange market, coal fired power plants are faced with new economically challenges.

Antimicrobial use in food animal production: situation analysis and contributing factors

Ziping WU

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 3,   Pages 301-311 doi: 10.15302/J-FASE-2018207

Abstract:

By measuring the quantity and ways in which antimicrobials are used, and reviewing different technical and socioeconomic factors influencing antimicrobial use at farm level, this study discusses the main knowledge gaps in antimicrobial use in food animal production and provides recommendations for future research and policy development. The review reveals that antimicrobial use in food animals exhibit strong regional and species differences, and there are still large information gaps concerning the current state of antimicrobial use. Factors associated with animal health (including antimicrobial resistance), animal health improvement, economic costs and benefits relevant to animal diseases, and potential technological alternatives or alternative systems all have an impact on antimicrobial use on the farm. There is a clear need to resolve the data gap by monitoring antimicrobial use and developing an analytical framework to better understand farmer behaviors under different technical, economic and environmental circumstances.

Middle East respiratory syndrome coronavirus: current situation and travel-associated concerns

Jaffar A. Al-Tawfiq,Ali S. Omrani,Ziad A. Memish

Frontiers of Medicine 2016, Volume 10, Issue 2,   Pages 111-119 doi: 10.1007/s11684-016-0446-y

Abstract:

The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 brought back memories of the occurrence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. More than 1500 MERS-CoV cases were recorded in 42 months with a case fatality rate (CFR) of 40%. Meanwhile, 8000 cases of SARS-CoV were confirmed in six months with a CFR of 10%. The clinical presentation of MERS-CoV ranges from mild and non-specific presentation to progressive and severe pneumonia. No predictive signs or symptoms exist to differentiate MERS-CoV from community-acquired pneumonia in hospitalized patients. An apparent heterogeneity was observed in transmission. Most MERS-CoV cases were secondary to large outbreaks in healthcare settings. These cases were secondary to community-acquired cases, which may also cause family outbreaks. Travel-associated MERS infection remains low. However, the virus exhibited a clear tendency to cause large outbreaks outside the Arabian Peninsula as exemplified by the outbreak in the Republic of Korea. In this review, we summarize the current knowledge about MERS-CoV and highlight travel-related issues.
