Construction of Strategic Early-Warning System in Cyberspace

Zhuang Honglin, Yao Le, Wang Sheng, Gu Jiaxiang, Wu Ye, Xie Kai

Strategic Study of CAE 2021, Volume 23, Issue 2,   Pages 1-7 doi: 10.15302/J-SSCAE-2021.02.001

Abstract:

Cyberspace strategic early-warning is a monitoring and warning system that is established by a country or group for early detection, tracking, identification, and notification of incoming major cyber attacks or the spreading destruction of powerful viruses. It’s an important component of a national security defense system. The implementation of the national cyber development strategy in China requires high attentions to the construction of a cyberspace strategic early-warning system. This study analyzes the major characteristics and basic requirements of strategic early-warning in cyberspace, and studies four major warning styles: security vulnerabilities, security threats, intrusion attacks, and abnormal behaviors warning. It also emphasizes four key projects, namely cyberspace surveying and mapping system, vulnerability collection and early-warning platform, threat intelligence perception and push system, as well as security monitoring and comprehensive early-warning system, after summarizing the construction of strategic early-warning and monitoring systems in cyberspace in China and abroad. Furthermore, we propose several countermeasures and suggestions, including strengthening high-level coordination, focusing on multi-source data integration, establishing professional earlywarning agencies, conducting regular security assessments, and implementing threat and early-warning grading mechanisms.

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.

Will Germany move into a situation with unsecured power supply?

Harald SCHWARZ

Frontiers in Energy 2019, Volume 13, Issue 3,   Pages 551-570 doi: 10.1007/s11708-019-0641-z

Abstract: Together with a huge number of other countries, Germany signed the Paris Agreements in 2015 to prevent global temperature increase above 2°C. Within this agreement, all countries defined their own national contributions to CO reduction. Since that, it was visible that CO emissions in Germany decreased, but not so fast than proposed in this German nationally determined contribution to the Paris Agreement. Due to increasing traffic, CO emissions from this mobility sector increased and CO emission from German power generation is nearly constant for the past 20 years, even a renewable generation capacity of 112 GW was built up in 2017, which is much higher than the peak load of 84 GW in Germany. That is why the German National Government has implemented a commission (often called “The German Coal Commission”) to propose a time line: how Germany can move out of coal-fired power stations. This “Coal Commission” started its work in the late spring of 2018 and handed over its final report with 336 pages to the government on January 26th, 2019. Within this report the following proposals were made: ① Until 2022: Due to a former decision of the German Government, the actual remaining nuclear power generation capacity of about 10 GW has to be switched off in 2022. Besides, the “Coal Commission” proposed to switch off additionally in total 12.5 GW of both, hard coal and lignite-fired power plants, so that Germany should reduce its conventional generation capacity by 22.5 GW in 2022. ② Until 2030: Another 13 GW of German hard coal or lignite-fired power plants should be switched off. ③ Until 2038: The final 17 GW of German hard coal or lignite-fired power plants should be switched off until 2038 latest. Unfortunately the “Coal Commission” has not investigated the relevant technical parameter to ensure a secured electric power supply, based on German’s own national resources. Because German Energy Revolution mainly is based on wind energy and photovoltaic, this paper will describe the negligible contribution of these sources to the secured generation capacity, which will be needed for a reliable power supply. In addition, it will discuss several technical options to integrate wind energy and photovoltaic into a secured power supply system with an overall reduced CO emission.
