“…Denial of service (DoS) attack is a method used to disrupt legitimate users' access to the target network or website resources [33][34][35]. Usually this is achieved by overloading a target with a large amount of traffic (usually a web server), or by sending malicious requests that cause the target resource to malfunction or completely collapse [36][37][38][39][40][41].…”

Distributed storage can store data in multiple devices or servers to improve data security. However, in today's explosive growth of network data, traditional distributed storage scheme is faced with some severe challenges such as insufficient performance, data tampering, and data lose. A distributed storage scheme based on blockchain has been proposed to improve security and efficiency of traditional distributed storage. Under this scheme, the following improvements have been made in this paper. This paper first analyzes the problems faced by distributed storage. Then proposed to build a new distributed storage blockchain scheme with sharding blockchain. The proposed scheme realizes the partitioning of the network and nodes by means of blockchain sharding technology, which can improve the efficiency of data verification between nodes. In addition, this paper uses polynomial commitment to construct a new verifiable secret share scheme called PolyVSS. This new scheme is one of the foundations for building our improved distributed storage blockchain scheme. Compared with the previous scheme, our new scheme does not require a trusted third party and has some new features such as homomorphic and batch opening. The security of VSS can be further improved. Experimental comparisons show that the proposed scheme significantly reduces storage and communication costs.

“…Li Zhou believed that the discharges of three wastes (i.e., waste gas, waste water, and industrial residue) in eastern and western China didn't reach the turning point [26][27][28]. Taking industrial emissions and discharged pollutants as environmental quality indicators, and based on the large amount of data collected from 1981 to 2004, Li Rui'e concluded that the pollutant like industrial SO 2 possessed an obvious characteristic of Environmental Kuznets Curve (EKC), and the income turning point was lower than that of the developed countries [29][30][31][32]. Li Bing studied the influence of the air pollution Kuznets curve by constructing a generalized matrix model and employing the panel data ranging from 2000 to 2011.…”

With the rapid development of the economy, China's environment has been damaged severely, which has attracted much attention from scholars and the local government. The concept of green development has been an underlying trend since 2012, and it is of great significance to explore the relationship between economic growth and environmental quality. Huzhou is a prefecture-level city under the jurisdiction of Zhejiang Province, and it is one of the 27 cities in the central area of the Yangtze River Delta. In recent years, this city develops well not only in economic development but also in maintaining a green environment. In the paper, the back propagation neural network is used to evaluate the local environmental quality. Meanwhile, the panel model is exploited to analyze the relationship between economic growth and environmental quality. All the data presented in the paper range from the year 2008 to 2018. Theoretical analysis indicates that the evaluation value of environmental quality, the emissions of industrial SO 2 , and waste water exhibit an inverted U-shaped relationship with economic growth. As for the regression results, the inflection point of income in the environmental Kuznets curve of the model which takes the evaluation value of the environmental quality as a dependent variable is higher than that of the model which takes the SO 2 emission as an independent variable. The research result would help the local government to take appropriate countermeasures to improve the environment and economy.

“…In terms of research on day surgery, foreign countries have abundant research contents. They are good at using scientific research and management tools, and have achieved great achievements in definition, acquisition, nursing, patient satisfaction, therapeutic effect, anesthesia, economic benefits, postoperative recovery and other aspects of day surgery [8][9][10]. Domestic studies on day surgery mainly focus on the definition, development direction, existing problems [11][12][13], effect evaluation [14][15][16], and access of nurses and physicians [17][18][19], etc., while there are few studies on patient awareness and satisfaction [3][4][5], as well as the application of professional quality management tools.…”

The day surgery management mode is mainly decentralized management, with clinical departments as the unit, and with reference to the experience of inter project operation management in benchmark hospitals, the empirical management is implemented. With the development of day surgery, the extensive decentralized management mode has been unable to meet the needs of the current day surgery development situation. At first, the paper carefully analyzes the existing problems in the day surgery process in the day ward of the Children's Hospital of Nanjing Medical University. And then, the concerns of doctors, nurses, anesthesiologists and other hospital staff in day ward, children and their parents are considered. Based on Bayesian decision-making theory, this paper optimizes the pre-admission evaluation of sick children and hospitalization process for day surgery in Nanjing Children's Hospital. Moreover, the specific optimization process is designed. After the optimizations, it can be seen that the time consumption of each step of the hospitalization process in day surgery is reduced. Thus, the hospital stay of sick children are significantly reduced, and the operation cost is reduced. In addition, the first preoperative preparation time and the average time of receiving children were reduced in day ward. The satisfaction of children's parents was significantly improved.
