The effect of risk perception and COVID‑19 anxiety in pregnancy on decision‑making via the Internet and prenatal care quality:A cross‑sectional multivariate analysis

Background:Risk perception and COVID‑19 anxiety in pregnant women restrict access to health services,cause pregnant women to resort to alternative channels such as the Internet,and affect prenatal care quality(PCQ)negatively.Purpose:The purpose of this study was to examine the effect of risk perception and COVID‑19 anxiety in pregnancy on decision‑making via the Internet(DMI)and PCQ with multivariate analysis.Materials and Methods:This cross‑sectional study was conducted with 406 pregnant women selected using the convenience sampling method in a training and research hospital,in Turkey.The data were collected using the information form,the perception of pregnancy risk questionnaire,the Coronavirus Anxiety Scale,the DMI Scale,and the PCQ Scale.The data obtained were subject to descriptive analysis and the multivariate analysis of variance.Results:Approximately 24.9%of the pregnant women were found to have a high perception of risk and 18%had symptoms of COVID‑19 anxiety.Pregnant women with high COVID‑19 anxiety and a higher perception of risk perceived the Internet as less influential for decision‑making(P<0.05).Pregnant women with a high‑risk perception had lower PCQ(P<0.05).Conclusion:The findings can be used to enhance mental health and resilience in pregnant women and to formulate appropriate intervention strategies.

Privacy Protection Algorithm for the Internet of Vehicles Based on Local Differential Privacy and Game Model

In recent years,with the continuous advancement of the intelligent process of the Internet of Vehicles(IoV),the problem of privacy leakage in IoV has become increasingly prominent.The research on the privacy protection of the IoV has become the focus of the society.This paper analyzes the advantages and disadvantages of the existing location privacy protection system structure and algorithms,proposes a privacy protection system structure based on untrusted data collection server,and designs a vehicle location acquisition algorithm based on a local differential privacy and game model.The algorithm first meshes the road network space.Then,the dynamic game model is introduced into the game user location privacy protection model and the attacker location semantic inference model,thereby minimizing the possibility of exposing the regional semantic privacy of the k-location set while maximizing the availability of the service.On this basis,a statistical method is designed,which satisfies the local differential privacy of k-location sets and obtains unbiased estimation of traffic density in different regions.Finally,this paper verifies the algorithm based on the data set of mobile vehicles in Shanghai.The experimental results show that the algorithm can guarantee the user’s location privacy and location semantic privacy while satisfying the service quality requirements,and provide better privacy protection and service for the users of the IoV.

Using Artificial Intelligence in the Internet of Things

The Internet of Things （IoT） has received much attention over the past decade. With the rapid increase in the use of smart devices, we are now able to collect big data on a daily basis. The data we are gathering （and related problems） are becoming more complex and uncertain. Researchers have therefore turned to artificial intelligence （AI） to efficiently deal with the problems ereated by big data.

Telecommunication Business Model in the Internet Era

The Internet is the best practice of Next Generation Network (NGN). One goal of NGN is to change the telecommunication network from a 'monopolized and closed' one into a 'competitive and open' one. The network service providers will offer high-quality, low-cost and colorful services while the traditional telecommunication operators will gradually develop into the network access providers and not directly participate in any specific service. In the service-dominated future, the telecommunication industry will be horizontally integrated with other active industries, such as consumption, entertainment and shopping, into an open, distributed and operable win-win ecological chain. In the new win-win situation, the users will be the biggest beneficiary.

Pandora’s Box in the Internet Era

Opportunities and Challenges Brought by the Internet

The Internet has made an important part of the national information infrastructure of China. Without the Internet, social informationization cannot be popularized to an extent as today. Upon the coming of a new year, we especially invited Mr. Jiang Lintao, a famous communication expert and the chief engineer of China Academy of Telecommunication Research of the Ministry of Information Industry, to give us his opinions on the opportunities and challenges brought by the Internet. According to Mr. Jiang, the appearance of the Internet has brought great impact on telecommunications networks. It has broken the monopoly of the telecom industry in telecom services and promoted the development of technologies. Characterized by continuous innovation and aggressiveness, Internet services guarantee their dominating position in broadband networks, and put the telecom industry in a quite passive position. The telecom industry is still looking for new development direction and breakthroughs in technology so as to regain its leading position. Mr. Jiang also pointed out that the future of both telecom networks and the Internet should be next generation network, which will be the main body of the future national information infrastructure. The essential features of the next generation network should be as follows: it should be secure and trustworthy enough to safeguard users’ rights, national security and social stability; it should be scalable enough to allow sustainable development; it should be compatible with current main technologies, co-exist with them and allow their graceful evolution; and it should provide a network platform for everybody to innovate.
