How does the "Digital Silk Road" help realize the goal of sustainable development? Guo Huadong, an academician of the China Academy of Sciences, said here on the 7th that the realization of sustainable development goals and specific indicators requires actions at the global, national and local levels, and big earth data can provide information, goals and assistance for these efforts and activities.
　　The second Digital China Construction Summit is being held in Fuzhou, and the A-class strategic pilot science and technology project "Earth Big Data Science Project" of China Academy of Sciences brought scientific research results to the summit.
　　Earth big data is the big data formed by the intersection and integration of earth science, information science and space science and technology. The data comes from but is not limited to space-based observation data, but also includes land, ocean, atmosphere and data related to human activities.
　　Guo Huadong, head of the project, chairman of the Digital Silk Road International Science Program and academician of the Chinese Academy of Sciences, was interviewed by a reporter from China News Service during the summit, and talked about how to conduct research based on the global big data project and the digital "Belt and Road" project to provide decision support and technical support for the United Nations Sustainable Development Goals (SDGs).
　　Guo Huadong pointed out that big data on earth is one of the key core technologies to realize the 2030 Agenda for Sustainable Development. It is the common demand of the countries along the Belt and Road to bring the global big data into the process of sustainable development and realize the coordinated development of society, culture, environment and ecology in the region and across countries through the advanced scientific and technological support of the global big data.
　　In 2016, China scientists initiated the Digital Silk Road International Science Program (DBAR) to realize the scientific service of global big data in the sustainable development goal of "Belt and Road" by sharing data, experience, technology and knowledge, and 53 countries, international organizations and international programs participated in it. At present, China Academy of Sciences has allocated more than 200 million yuan in the next five years to support the implementation of the DBAR plan.
　　"The DBAR plan will systematically monitor the status quo and evolution pattern of different ecosystems in the Belt and Road, including grasslands, forests, glaciers, cities, farmland and coastal zones." Guo Huadong said that the continuous accumulation, opening and sharing of global big data is an important resource and driving force to promote the development of digital "Belt and Road" scientific and technological innovation.
　　In January 2019, the DBAR earth big data system platform was officially launched. The system includes thematic data sets such as resources, environment, climate, disasters and heritage in the "Belt and Road" region, and 57 types of independent intellectual property data products. The shared data exceeds 120 trillion bytes, which can realize the browsing of basic geographic data throughout the "Belt and Road".
　　In January 2018, China Academy of Sciences launched the A-class strategic science and technology pilot project "Earth Big Data Science Project", aiming at building the world’s leading Earth Big Data platform and database, and promoting technological innovation, major scientific discoveries and one-stop all-round macro-decision support of Earth Big Data.
　　Guo Huadong said that in 2019, the core work of the Global Big Data Project will be the construction of "five balls, one satellite, one facility and 6SDG", and research will be carried out on several SDG targets, and efforts will be made to promote the monitoring and evaluation of six SDG indicators of the Global Big Data Service SDG2 Zero Hunger, SDG6 Water Resources, SDG11 Urbanization, SDG13 Climate Action, SDG14 Marine Ecology and SDG15 Terrestrial Ecology.
　　According to Guo Huadong, from 2018 to 2019, the earth big data technology was specially used to dynamically monitor the construction status of 127 overseas industrial parks in China from the establishment of the park to the end of 2018, and to monitor and evaluate the distribution pattern, development trends, construction status, resource endowment, risk status, ecological environment and socio-economic impact of overseas industrial parks in China.
　　At the same time, help those developing countries without technical and financial resources to monitor their urban development and study the relationship between land use rate and population growth rate; The evolution characteristics of giant panda habitat in China in recent 40 years were evaluated, which provided methods and data support for the realization of the biodiversity goal of SDG15 of the United Nations. Customize the special Portuguese agricultural monitoring system, carry out detailed agricultural monitoring training for Mozambique, and continuously provide solid technical support and decision support for promoting technological innovation in the field of earth big data and achieving SDGs goals.

Eight-year-old Liang Liang got a new cigarette card, and he sniffed the residual smell of tobacco excitedly. This card became a new "general" in his cigarette card collection. Recently, a game called "Cigarette Card Shooting" has quietly sprung up in primary schools all over the country. Children use cards folded from discarded cigarette cases to play against each other, and the winners can get each other’s cards. Among them, cigarette cards of high-end cigarette brands are more popular, which has spawned a "trading market" among children.

Parents found that children’s obsession with cigarette collecting cards was beyond imagination. Some children even look for discarded cigarette cases from parents who smoke or in trash cans to increase their "collection". At the same time, a large number of information about selling cigarette cards appeared on the e-commerce platform, with different prices ranging from a few yuan to a few cents. Some merchants claimed that the cigarette cards they sold were genuine, although the source was unknown, but they emphasized that they had been disinfected and met the safety standards required by parents.

However, this cigarette card craze has aroused social concern and concern. Many market supervision departments and educational institutions have initiated initiatives to prohibit students from participating in the "cigarette card" game, pointing out its potential harm to the physical and mental health of minors. Legal experts pointed out that selling tobacco cards to minors violates the Law on the Protection of Minors and the Advertising Law, which may not only induce minors to contact tobacco advertisements, but also infringe on the exclusive right to use registered trademarks. All walks of life are called upon to work together to create a smoke-free environment and protect young people from the temptation of tobacco.

In view of this phenomenon, some experts suggest developing healthy card games suitable for teenagers to guide children’s interest in a positive way, instead of cigarette card games that may have adverse effects.

　First, the development of basic Internet activities

　(A) basic information Internet applications

E-mail is one of the earliest Internet services, which plays an important role in information communication, and is also a widely accepted and low-cost Internet marketing channel for enterprises. As of December 2015, 89.0% of enterprises connected to the Internet have used the Internet to send and receive emails in the past year, and 62.1% of them have corporate mailboxes.

In addition, 71.9%, 67.2% and 58.3% of online enterprises have carried out basic information activities such as learning about goods or services, publishing information or instant messages, and obtaining information from government agencies.

　(B) Basic internal support Internet applications

Internet plays an important supporting role in the internal management of enterprises: 83.0% online enterprises assist financial work through online banking; 79.3% of online enterprises interact with government agencies and do things online, and the high utilization rate reflects the fruitful results of e-government construction; 57.4% of online companies are engaged in online recruitment. In addition to traditional ways such as posting recruitment information on recruitment websites and official website, social platforms and instant messaging tools have also become new channels, and 28.1% of online companies use the Internet to carry out employee training.

　(3) Basic network security protection measures

By December 2015, 91.4% of enterprises had installed antivirus software and firewall software, and more than 1/4 of them paid for it. According to the survey results, enterprises in China have basic awareness of network security protection.

　Second, the grassroots Internet full-time job setting

As of December 2015, 34.0% of enterprises have set up full-time Internet posts at the grassroots level, among which the proportion of micro-enterprises with 7 employees or less is the lowest, accounting for 30.2%, and the proportion of enterprises with 300 employees or above setting up special posts is close to 40%. At present, it is difficult for small and medium-sized enterprises to set up special posts. However, with the gradual improvement of Internet software and hardware configuration and the increasingly extensive and in-depth development of Internet activities, the demand for talents with professional operation and maintenance, R&D and commercial operation skills will surge.

In terms of industries, the proportion of special posts in industry and service industry is 28.5% and 38.0% respectively, with a difference of nearly 10 percentage points. Among them, the manufacturing industry is lower than the whole industry, and the wholesale and retail catering industry is lower than the whole service industry. It is an urgent problem to improve the attention paid by enterprises to grassroots professionals in order to realize "intelligent manufacturing" and develop modern service industry closely related to people’s livelihood.

The following article comes from science and technology innovation board Daily by Song Ziqiao.

On June 6th, Netling, a private enterprise in China, released the first domestic consumer-grade satellite Internet terminal equipment-Netling Satellite Internet Access Machine, which only provides high-speed and low-delay satellite broadband service for remote areas without signal. The product is divided into two versions, the standard version costs 29,800 yuan, and the Pro version costs 49,800 yuan. The product has been put on sale in the company’s self-built mall, and users need to buy satellite traffic in addition to the terminal.

Netling satellite internet access machine

This product is aimed at Starlink terminal, a consumer-grade satellite Internet access device of Mark Musk. SpaceX sells the standard version of Starlink terminal at a unit price of $599, and the high-performance version is priced at $2,500.

Third generation Starlink terminal

Obviously, SpaceX has stronger cost control ability. Netling satellite communication equipment uses the public satellite network, and the Spacex satellite chain model is a whole chain, covering the whole chain from satellites, reusable launch vehicle manufacturing to satellite launch. The controllability of the number and cost of low-orbit satellites in the satellite chain is beyond the reach of all countries and institutions.

Focusing on the product, according to the official introduction, in terms of product volume, the antenna area of Netling satellite Internet access machine is reduced by 20% compared with the second generation Starlink terminal; Compared with the antenna with the same physical size, the performance is improved by 2 times; Adopting fully integrated mode, the fuselage thickness is only 49mm and the weight is about 4.5 kg; The back adopts the combination of X backboard design and breathing aura, which intuitively prompts the product’s star-seeking and networking status; The connected Asia-Pacific 6D Qualcomm Satellite can support up to 20Mbps/ uplink/100Mbps downlink bandwidth, and it actually enters the use scenario, which is enough to meet the basic network needs of up to 10 people. Dual Type-C interface, which supports uninterrupted power exchange and switching, and supports the support of docking station for wired network port, which is convenient for professional equipment connection; The adopted independent WI-FI amplifier has a maximum power of 100mw and an outdoor coverage radius of 50 m..

From the perspective of application scenarios, both of them are dedicated to serving communication scenarios that are not covered by terrestrial networks.

At the press conference, Liu Yu, executive vice president of Netling, said that China still has 60% of its territory and 3 million square kilometers of territorial waters without network coverage; And 2 million herders have no nets for half a year; In addition, 200,000 hard-core off-road vehicle customers every year are just-needed user scenarios of satellite broadband. Besides, as a China enterprise, there are broader market opportunities in the Belt and Road Initiative.

According to Wang Ling, the company has developed a variety of satellite broadband terminals, including satellite parabolic antennas, radio frequency devices, embedded software and hardware, etc., to realize intelligent functions such as automatic satellite alignment, OTA upgrade of products, and remote diagnosis. In addition, the company builds platform-based software to realize the online management and service operation of the terminal, and realizes the one-stop service ability of users in the life cycle of equipment through OneLinQ Netling APP.

However, both Netling and Starlink have a long way to go to popularize them to the public.

In addition to the equipment purchase price, users also have to pay the satellite communication bandwidth fee, and the price is the biggest obstacle to the smooth realization of the closed-loop business of this kind of products. The goal of not losing money was achieved when the Starlink terminal was online for more than two years and the number of users far exceeded 1.5 million.

According to public information, at present, the cost of satellite communication bandwidth in China is about 300 yuan per g, which can only be used for one hour in Tik Tok, and the standard version of the traffic package of Netling Internet access machine is priced at 320 yuan per g.. The monthly fee of the Starlink terminal is also high. In the latest price adjustment, for the "Global Roaming Plan" of the Starlink terminal, the fee for settlement users in US dollars increased from US$ 200 to US$ 400 per month, an increase of 100%.

Beijing News (Reporter Wu Tingting) With the arrival of the return peak, airlines not only do a daily "physical examination" for their planes, but also increase the replacement frequency of the "air purifier"-high efficiency particulate air filter (hereinafter referred to as "air filter") during the epidemic prevention and control period, which is like putting a mask on the plane. The reporter learned that at present, almost every plane returned from the epidemic-prone area of various airlines needs to replace the air filter immediately to ensure the clean air in the cabin.

　

The frequency of air filtration for aircraft replacement is accelerated.

On February 3, the Civil Aviation Administration of China issued a notice, which made a number of requirements for epidemic prevention and control during the return trip. Among them, it was clearly proposed to clean the air conditioning system of the aircraft and increase the frequency of inspection and replacement of high-efficiency particulate air filters. In layman’s terms, HEPA is like an air purifier for home use, but this "air purifier" on the plane is more powerful than domestic equipment.

　

The relevant person in charge of China Southern Airlines said that this kind of air filtration on the plane can block the passage of 99.97% bacteria and virus particles, and the new filter material also has disinfection and sterilization functions. Sheng Liyao, director of the Fourth Workshop of Airbus Route Department of Hongqiao Maintenance Base of China Eastern Airlines Technology Company, introduced that the air in the aircraft cabin comes from two parts, one is fresh air, and the other is recycled cabin air, so the high-efficiency particulate air filtration can keep the air in the cabin fresh and clean.

　

Although the aircraft air filtration function is powerful, it still cannot be taken lightly in the face of epidemic prevention and control. Sheng Liyao said that since New Year’s Eve, all the planes of China Eastern Airlines flying to epidemic-prone areas and transporting medical staff to Wuhan and other places need to be replaced. Only today, in Hongqiao Airport, Sheng Lihao replaced the air filters for seven Airbus aircraft of China Eastern Airlines. "This does not include Pudong Airport and Boeing aircraft with air filters."

　

Liu Liwei, the relevant person in charge of the epidemic prevention and control office of China United Airlines, said that all the flights of the company returning to Beijing from the epidemic-prone areas will be replaced in time. "It used to be replaced regularly, but now it is changed when it flies back."

　

The relevant person in charge of China Southern Airlines also said that the cabin recirculation system of China Southern Airlines fleet is equipped with high-efficiency particulate air filter, and it is regularly replaced. The current effective measures are enough to ensure the air freshness and cleanliness of the recirculation system.

Sheng Linghao told reporters that taking the Airbus model as an example, the Airbus 320 model has two air filters and the Airbus 330 model has eight air filters. With the increase of the frequency of replacing the air filter, the work intensity of the crew is also increasing, and in this special period, the crew also needs to wear protective clothing and goggles to replace the air filter for the aircraft.

　

On January 28th, Wu Yan, the release officer of China Eastern Airlines Technology Sichuan Branch, volunteered to disinfect three planes in depth and replace the air filter for the recirculation fan of the air conditioning system. Because of the special situation of the aircraft, it is necessary to minimize the impurities left in the air on the air filter, and the crew must be more cautious and careful.

　

Wu Mi recalled that he and Feng Zhang, the maintenance personnel, had carefully prepared for technical disposal and had in-depth exchanges with epidemic prevention personnel. Subsequently, they put on protective clothing, protective glasses, masks and gloves, and began to replace the air filter. The cargo hold of Boeing 737 is relatively closed, stuffy and unventilated, and the space is narrow, so it can only squat on the floor when working. When replacing the air filter, in order to make the impurities on the air filter not remain in the air as much as possible, they dared not be careless, and assembled and disassembled it more carefully and cautiously. With full preparation and superb technical ability, the work was completed one hour ahead of schedule.

　

The reporter also learned from China Southern Airlines that during the epidemic prevention and control period, all the crew members put on protective clothing to replace the air filter.

In view of the return peak, the Civil Aviation Administration proposed to increase the frequency of deep cleaning and disinfection of aircraft cabins and cockpits. The reporter learned from many airlines, such as China Eastern Airlines, China Southern Airlines, Air China and China United Airlines, that all companies have formulated cabin disinfection plans. Take China United Airlines as an example. At present, the company has 52 flights at Daxing Airport. After disembarking on each flight segment, the flight attendants will disinfect the cabin models. In addition, China United Airlines also hired a professional company to deeply disinfect the aircraft, and has already deeply disinfected all flights. Liu Liwei introduced that because the cockpit is very important, the disinfection here is done by the crew.

　

During the epidemic period, the fleet of China Southern Airlines increased the frequency of disinfection and clarified the disinfection standards. The disinfection scope was stipulated in the plan, including aircraft cabin space, toilets, garbage rooms, etc., and detailed provisions were made in terms of disinfection personnel, medicines, equipment, protective articles, disinfection methods and procedures.

　

Air China’s fleet has also increased the frequency of disinfection. In the post-flight cleaning operation of each aircraft, preventive disinfection is carried out for every place that passengers and crew can touch, including cockpit, cabin small table board, seat armrest, porthole sun visor, luggage rack and toilet. In view of the fever passengers on the plane or the flight carrying out the emergency charter mission to Wuhan, after receiving the notice, the epidemic prevention personnel of Air China immediately boarded the plane to carry out atomization emergency disinfection of the cabin environment.
