The Realistic Pattern and Path Choice of the Development of Agricultural Software Industry

Ma Chen, Li Jin, Zhang Qian, Feng Xian, Jie Xiaojing

Strategic Study of CAE 2021, Volume 23, Issue 4,   Pages 19-29 doi: 10.15302/J-SSCAE-2021.04.003

Abstract:

As the integration of information technology and agricultural development accelerates, the agricultural software industry has emerged to support the development of smart agriculture. In this article, we first analyze the development status of and challenges faced by China’s agricultural software industry by analyzing the development strategies of the industry in China and abroad and using literature review and survey data. Subsequently, we propose the strategic goals, major engineering projects, and policy measures for the development of China’s agricultural software industry. China’s agricultural software industry has a large gap with other countries in terms of technology development and promotion, enterprise operation, and user accumulation. The major challenges include difficulty in development, weak innovation capabilities, low return on investment, and insufficient protection of intellectual property rights, restricting the growth of China’s agricultural software industry. China should regard the software development of agricultural technologies as the main line and focus on strengthening the innovative capabilities of its agricultural software industry by 2035. The major engineering projects we proposed involve agricultural enabling software and platform development, precision agriculture management software application promotion, agricultural software industry cluster establishment, and agricultural software enterprise cultivation. Furthermore, China should improve its policy support system, strengthen the overall coordination mechanism, optimize the discipline system, and strengthen talent training for the agricultural software industry.

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.

Abstract: Nowadays, pyogenic liver abscess (PLA) is still a common and severe intra-abdominal infection, and had emerged as the most common pathogenic bacteria worldwide in the past ten years. Our study aims to achieve an early pathogenic diagnosis and rational therapy modality for liver abscess (KLA) through clinical data analysis. A total of 197 inpatients in Zhongshan Hospital, Shanghai, diagnosed as having liver abscess between March 2001 and September 2009 were enrolled. Patients with monomicrobial infection were divided into two groups: patients with liver abscess (KLA group, =106) and those with non- liver abscess (NKLA group, =56). A retrospective analysis was made between these two groups on the aspects of underlying diseases, clinical characteristics, laboratory data, culture results, and imaging findings. To evaluate the effects of different medical interventions, monomicrobial KLA patients were further divided into four subgroups (percutaneous liver aspiration, aspiration plus antibiotics flushing, aspiration plus retained catheter, and aspiration plus antibiotics flushing and retained catheter), and corresponding therapeutic effects were analyzed. KLA was more likely to occur in patients with coexisting diseases such as diabetes mellitus (53.77% 25.00%, =0.001) and hepatic adipose infiltration (16.04% 5.36%, =0.029). Compared to NKLA group, clinical characteristics including abdominal pain (40.57% 57.14%, =0.044), hypodynamia (19.81% 46.43%, =0.001), and hepatomegaly (4.72% 14.29%, =0.033) were much milder, but with a higher fasting blood glucose level (7.84?±?0.36 5.76?±?0.30, =0.001) on admission in KLA group. In addition, KLA abscess often appeared singly in the right lobe of the liver with gas forming nature (32.88% 13.51%, =0.039), unsmooth rim (71.23% 40.54%, =0.002), and dynamic septum enhancement (41.10% 16.22%, =0.009). Compared to mono aspiration subgroup, additional antibiotic flushing could not further improve clinical outcomes of KLA patients ( >0.05); however, the retained catheter showed obvious advantage in reducing abscess diameter (34.38?±?3.25 mm 22.67?±?2.37 mm, =0.017). It can be concluded that the strong association with diabetes, milder clinical symptoms, and gas-forming nature in CT images makes early pathogenic diagnosis of KLA possible. Comparatively, ultrasonography-guided percutaneous liver aspiration with retained catheter may be the most rational intervention modality of KLA.

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.
