A Review of Major Viewpoints on Cyber Sovereignty around the World

Zhu Shibing,Zhang Xuebo and Wang Yu,Liu Yunjie

Strategic Study of CAE 2016, Volume 18, Issue 6,   Pages 89-93 doi: 10.15302/J-SSCAE-2016.06.018

Abstract:

As well as bringing great convenience, cyberspace poses new problems and challenges. Cyber sovereignty, in particular, constitutes the basic principle for solving national interest conflicts that arise in the process of cyberspace development. This paper provides a review and an analysis of three typical viewpoints on cyber sovereignty from around the world; namely, advocating for cyber sovereignty, opposing it, or being indifferent to it. We also give an overview of the attitudes of important international organizations and major countries toward cyber sovereignty. Our purpose is to provide an objective description of the cyber sovereignty situation.

Analysis of the treatment outcomes of esophageal variceal bleeding patients from multiple centers in

Frontiers of Medicine 2008, Volume 2, Issue 2,   Pages 171-173 doi: 10.1007/s11684-008-0031-0

Abstract: This study aimed to investigate the treatment outcomes of esophageal variceal bleeding (EVB) in China. A total of 1087 cases were collected from 19 hospitals in 16 large and medium sized cities across China between January 1st, 2005 and January 1st, 2006. There were 313 cases (29.0%) of mild (<400 mL), 494 cases (45.8%) of moderate (400–1500 mL) and 272 cases (25.2%) of severe (>1500 mL) bleeding. Successful hemostasis was achieved in 89.8% of cases. Seven hundred and eighty-five cases were treated by medication with a hemostasis rate of 91.8%. Seventy-one cases were treated using a Sengstaken-Blakemore tube with a hemostasis rate of 54.9%. Thirty-seven cases were treated with emergency endoscopic variceal ligation with a hemostasis rate of 83.8%. Seventy-seven cases were treated with endoscopic sclerotherapy with a hemostasis rate of 94.8%. Forty-three cases were treated with emergency surgical operation with a hemostasis rate of 95.3%. Sixty-six cases were treated with combined therapy with a hemostasis rate of 97.0%. There was a significant difference ( < 0.01) in the successful hemostasis rate between different treatments. The overall mortality was 10.1%, among which 6.6% was directly caused by bleeding. The multivariate logistic regression analysis shows that the severity of bleeding, treatment methods, liver dysfunction and activation of hepatitis were predictive factors for successful hemostasis. Most cases of EVB were mild and moderate in severity. The first-line treatment for EVB is medication. Emergency endoscopic intervention has not been widely available yet. The overall management outcome of EVB has been improved.

Sensitivity analysis of the deterioration of concrete strength in marine environment to multiple corrosive

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 2,   Pages 175-190 doi: 10.1007/s11709-021-0791-z

Abstract: The corrosion degradation behavior of concrete materials plays a crucial role in the change of its mechanical properties under multi-ion interaction in the marine environment. In this study, the variation in the macro-physical and mechanical properties of concrete with corrosion time is investigated, and the source of micro-corrosion products under different salt solutions in seawater are analyzed. Regardless of the continuous hydration effect of concrete, the damage effects of various corrosive ions (Cl–, SO42−, and Mg2+, etc.) on the tensile and compressive strength of concrete are discussed based on measurement in different salt solutions. The sensitivity analysis method for concrete strength is used to quantitatively analyze the sensitivity of concrete strength to the effects of each ion in a multi-salt solution without considering the influence of continued hydration. The quantitative results indicate that the addition of Cl– can weaken the corrosion effect of SO42− by about 20%, while the addition of Mg2+ or Mg2+ and Cl– can strengthen it by 10%–20% during a 600-d corrosion process.
