BEIJING, Beijing, June 25 (Xie Yanbing, Liang Xiaohui) Zang Tiewei, spokesman of the the National People’s Congress Standing Committee (NPCSC) Law Commission, said in Beijing on the 25th that the third session of the 14th the National People’s Congress Standing Committee (NPCSC) will continue to review the draft law on barrier-free environment construction, and the third review draft of the draft intends to clarify that people’s governments at or above the county level should formulate targeted plans for the renovation of barrier-free facilities and organize their implementation.

　　On the same day, the National People’s Congress Standing Committee (NPCSC) Legal Affairs Committee held a press conference. Zang Tiewei said at the press conference that the draft law on barrier-free environment construction has been reviewed twice, and the three drafts submitted to the Standing Committee for consideration are proposed to be revised as follows:

　　First, it is added that the construction of barrier-free environment should be combined with the aging transformation.

　　Second, it is clear that people’s governments at or above the county level should formulate targeted renovation plans for barrier-free facilities and organize their implementation.

　　The third is to improve the regulations for installing elevators and other barrier-free facilities in existing houses. The range of residential buildings equipped with elevators and other barrier-free facilities is clearly defined as "existing multi-storey residential buildings in old urban communities", and at the same time, it is added that "giving play to the role of community grassroots organizations" and "strengthening communication and consultation" by house owners.

　　Fourth, increase the provisions on encouraging the preparation and publication of teaching books in Braille and low vision.

　　Fifth, expand the scope of places that provide barrier-free facilities, equipment and services to museums, cultural centers, science and technology museums and other places.

　　Sixth, improve the provisions for commodity producers and operators to provide labels and instructions in barrier-free formats.

　　Seventh, it is clear that the local standards for barrier-free environment construction shall not be lower than the relevant technical requirements of national standards.

　　Eighth, improve the regulations that encourage and support the development and application of related technologies. (End)

Brand has existed for centuries, and its emergence marks the maturity of the concept of commodity exchange. It can be said that the appearance and development of brand is a social and economic phenomenon and the product of the development of commodity economy to a certain stage.

1. Development history of foreign brands

Brand development in western countries has roughly experienced four periods:

(1) primitive period. Before the invention of movable type printing in 1450, the brand developed in a primitive and unconscious state. However, people have unconsciously applied the concept of brand in business activities. At that time, with the prosperity of economy and the increase of business activities, people began to spread brands by word of mouth.

(2) the germination period. Before the industrial revolution, brand development was in its infancy. At that time, it mainly paid attention to the labeling of products or producers, so it was also called the labeling period. For example, in the western United States, the earliest entrepreneurs (that is, big farmers) branded the company’s logo on the buttocks of animals, and used such an indelible mark to show his ownership of the assets of animals. Since then, the brand has the function of distinguishing from other people’s goods.

(3) growth period. At the end of 18th century and the beginning of 19th century, or after the industrial revolution, western countries experienced rapid economic development, increased products and intensified competition, and brand development entered the growth period or trademark period. The biggest feature of brand development in this period is that enterprises generally attach importance to trademark registration.

The industrial revolution made the machine industry replace manual production, and the manufacturing industry was more developed. In order to strengthen the protection of brands, the trademark system came into being, and brands in the modern sense came into being. Starting with the first car with horizontal bar engine made in Germany in 1886, Coca Cola was born in 1886, Gillette shaver appeared in 1895, Kodak brand was born in 1898, Ford Model T came out in 1908, Boeing brand quietly landed in 1917, Marlboro brand came out in 1924, Nestle coffee came out in 1938, and a number of brands gradually developed and grew.

At the beginning of the 19th century, the earliest legal provisions on trademarks appeared in France. Subsequently, Britain, the United States, Germany and Japan have also promulgated their own trademark laws. Trademark system is popular all over the world, and brands have been recognized and guaranteed by law.

(4) maturity. At the end of 19th century and the beginning of 20th century, the role of brand as an important means of competition gradually emerged. Especially after the Second World War, with the rapid development of science and technology, high technology is widely used in production, enterprise groups are maturing, consumer demand is changing with each passing day, and enterprise competition is unprecedented fierce, thus ushered in the so-called "brand economy" era, and brand development has entered a mature period or brand period. The globalization trend of brand communication is obvious, but it has national characteristics. A large number of brands with unique connotations and advanced concepts have been born, and the research on brands has been deepened day by day. During this period, famous brands such as KFC, McDonald’s, Disney, Toyota, Hitachi, Panasonic and Sony appeared, which has entered the era of brand competition.

2. The development stage of foreign brands

Looking at the development history of foreign brands, it can be summarized into four stages, namely, the formal brand stage, the legal brand stage, the famous brand stage and the commercialized brand stage.

(1) The formalization stage of the brand. In the stage of brand development, the first is the formalization of the brand. From a formal point of view, a brand is a symbol. Since ancient times, people have marked their own livestock with unique marks to distinguish them from other people’s livestock. In English, the word "Brand" means to stamp, indicating the origin and manufacturer of a product or service. In the early days, people widely used formal brands, which started with all kinds of craftsmen marking their products to distinguish them from those made by others. At this stage, when people understand the brand, they only regard it as a form of symbol and mark, so that consumers can distinguish the origin and source of the product through this symbol. This symbol ensures that the product is provided by the same supplier with the same quality and characteristic level, and after the product is sold, it can make the buyer identify the manufacturer of the product and facilitate repair and replacement. This kind of formalized brand also has certain binding force on other product manufacturers, and to some extent, it has played a role in preventing its own products from being counterfeited by others.

(2) The legalization stage of the brand. The significance of brand legalization lies in brand trademark, and brand has become an integral part of intellectual property rights. According to the development of commodity economy and fierce market competition, many western countries have promulgated and promulgated trademark laws and related brand protection regulations, which makes the concept of brand clearly defined in law. Therefore, the brand of goods and services can be protected by law, and the word brand is also reflected in relevant laws. Legalization of brand shows in the legal sense that after the brand is registered, the owner and franchisor of the brand get the protectable property, and can also prevent others from impacting, counterfeiting and hurting. In 1803, France introduced the world’s earliest brand-related law, the Law on Factories, Workshops and Workshops, which defined counterfeiting other people’s trademarks as the crime of forging documents without permission and punished it. The United States began to implement the Federal Trademark Regulations of the United States of America in 1870; Germany also promulgated the Trademark Protection Law in 1874, which made the brand development enter the era of legalization. Brand-related laws that have been recognized and implemented around the world mainly include the Paris Convention for the Protection of Industrial Intellectual Property Rights, which was promulgated and implemented on March 20th, 1883, and the madrid agreement concerning the international registration of marks, which was promulgated and implemented on April 14th, 1891. China is also a member of these two conventions and agreements.

(3) the brand-name stage of the brand. After World War II, great changes have taken place in the world economy, scientific and technological progress has promoted the rapid development of productive forces, people’s material and cultural living standards have been greatly improved, consumers have changed from meeting basic physiological needs to pursuing higher psychologically and spiritually, paying attention to the expression and development of individuality, and there are abundant commodities in the market, and the differences in quality, performance and price of commodities have gradually narrowed. At the same time, due to the joint action of various modern media, the spread and diffusion of commodity brands are more effective and fast, which promotes and influences consumers to form the concept and value trend of brand-name consumption, and the outstanding performance of brand-name products in the market has brought rich super-value profits to enterprises. The demonstration effect of brand-name consumption is to cause people to chase brand-name goods all over the world. During this period, brand has become the focus of market competition among enterprises.

Brand-name brand has become the goal and direction of brand development for all enterprises. Brand-name brand is an outstanding brand among many brands. Brand-name brand goods are symbols of high-quality products and services. They occupy the market and conquer the high-quality goods of users and consumers with their outstanding performance and the appearance of appealing to both refined and popular tastes. From the market performance, the famous brand indicates that the enterprise’s labor is highly recognized by the society, reflects the trend of consumer psychological preference and cultural taste, is the unity of social material and spiritual values, and is the biggest feature of modern social consumption concept and cultural value orientation. During this period, many famous brands began to appear in various markets around the world, such as Coca-Cola drinks in the United States, Kodak films, Ford cars and Toyota cars in Japan. Famous brands have become a powerful weapon for enterprises to participate in international market competition in this period.

(4) the commercialization stage of the brand. When the world began to pay close attention to intellectual property rights, enterprise merger and brand export, and the implementation of franchising and other management, the formal meaning, legal attributes and branding of the brand could not fully explain the true meaning of the brand. It can be said that the nature of the brand has changed suddenly, that is, the brand has the characteristics of general commodity value and exchange function, and the commodity attributes of the brand have emerged. A brand is a commodity, which has the general attributes and characteristics of a commodity, and its development has entered the era of brand commercialization. Enterprises with brands pay more attention to the connotation of the brand and the intangible assets value of the brand itself.

When marketing activities are carried out, brands are integrated into business assets as intellectual property and intangible assets of enterprises. When enterprises merge and expand, brand assets have become an important asset composition of asset merger and reorganization. Even the brand can be auctioned as an independent asset when the enterprise goes bankrupt. For example, the famous British car brand manufacturer "Rolle Period-Roy Period" was transferred to the German Volkswagen Company at a price of hundreds of millions of pounds during the merger of the enterprise. Developed countries make use of the commodity characteristics of brands to export brands to developing countries in the international market, and adopt the way of licensing brands as an investment in local enterprises, implement franchising and realize the brand expansion strategy. For example, in many Coca-Cola production plants and filling lines around the world, the Coca-Cola Company has no direct investment, but only provides licenses for the use of Coca-Cola stock solution and Coca-Cola brands, and enterprises that use brands have to pay a considerable amount of brand use fees every year. Another example is the licensee who uses McDonald’s brand. In addition to the initial cost of about 600,000 US dollars, he will also pay McDonald’s brand service fee and brand use fee, which account for 11.5% of its operating income. It can be said that the era of brand commercialization has arrived. (The author is a member of the writing team of Brand Innovation)

    The State Council Information Office will hold a press conference in the press room of the State Council Information Office at 10 am on Tuesday, January 13th, 2015. Zheng Yuesheng, spokesperson of the General Administration of Customs and director of the General Statistics Department, will introduce the import and export situation in 2014 and answer questions from reporters.

    [Zheng Yuesheng, spokesperson of the General Administration of Customs and director of the General Statistics Department]2014 is the first year of China’s comprehensive deepening reform. In the past year, the world economy was still in a period of deep adjustment after the international financial crisis, and domestic economic development entered a new normal. Under the correct leadership and unified deployment of the CPC Central Committee and the State Council, various reforms in the foreign trade field were steadily advanced, and various regions, departments and foreign trade enterprises conscientiously implemented policies and measures to promote the stable growth of foreign trade. China’s foreign trade has continued to grow steadily and its operation has remained within a reasonable range. At the same time, China’s foreign trade import and export has also made positive progress in improving quality, improving efficiency and optimizing structure.

2. General trade grew steadily, while processing trade grew steadily. In 2014, China’s general trade import and export was 14.21 trillion yuan, up 4.2%, accounting for 53.8% of China’s total import and export value in the same period. In the same period, the import and export of processing trade was 8.65 trillion yuan, up 2.8%, accounting for 32.7%.

3. Bilateral trade with the EU and the United States grew steadily, trade with Japan and Hong Kong declined, and trade with emerging markets performed well. In 2014, the European Union, the United States, ASEAN, Hong Kong and Japan were my top five trading partners. Among them, my bilateral trade volume with the EU and the United States was 3.78 trillion yuan and 3.41 trillion yuan respectively, up by 8.9% and 5.4% respectively.

4. The import and export of private enterprises and foreign-invested enterprises increased, while the import and export of state-owned enterprises declined slightly. In 2014, the import and export of private enterprises was 9.13 trillion yuan, an increase of 6.1%, accounting for 34.5% of China’s total import and export value in the same period. In the same period, the import and export of foreign-invested enterprises was 12.19 trillion yuan, up 2.4%, accounting for 46.1%; The import and export of state-owned enterprises was 4.59 trillion yuan, down 1.3%, accounting for 17.4%.

5. Exports of mechanical and electrical products and traditional labor-intensive products grew steadily. In 2014, the export of mechanical and electrical products in China was 8.05 trillion yuan, an increase of 2.6%, accounting for 56% of the total export value. In the same period, the export of seven categories of labor-intensive products, such as textiles, clothing, luggage, footwear, toys, furniture and plastic products, was 2.98 trillion yuan, up by 4%, accounting for 20.7%.

6. Imports of consumer goods accelerated, while imports of major commodities increased in price and fell. In 2014, China’s imports of consumer goods reached 936.27 billion yuan, up by 14.9%, which was significantly faster than the overall growth rate of China’s imports in the same period, accounting for 7.8% of China’s total imports in the same period. In the same period, the import volume of major commodities maintained growth, including 930 million tons of imported iron ore, an increase of 13.8%; Imported crude oil was 310 million tons, up by 9.5%; 71.399 million tons of soybeans, an increase of 12.7%; 14.432 million tons of steel, an increase of 2.5%; 4.825 million tons of copper, an increase of 7.4%.

In the same period, the import prices of China’s imported commodities generally fell, with the average import price of iron ore falling by 23.4%, crude oil by 6.1%, coal by 15.2%, refined oil by 4.6%, soybean by 6.8% and copper by 6.1%.

Seven, foreign trade export leading index fell for the third consecutive month. In December, China’s foreign trade export leading index was 40.1, down by 0.7 compared with November, the third consecutive month of decline, the lowest point since December 2013, indicating that China’s export growth is still facing certain pressure in the first quarter of this year.

　　Recently, the General Office of the State Council issued the Guide for the Construction of the Technical System of "Internet+Government Services" (hereinafter referred to as "the Guide"), which is an important measure for the state to promote the overall layout of "five in one" and the coordinated promotion of the "four comprehensive" strategic layout, make great efforts to promote the structural reform of the supply side of the government, deepen the integration of decentralization and administration, optimize service reform, further optimize public services and innovate administrative management.

　　First, a deep understanding of the great significance of "Internet+government services"

　　(A) to promote the "Internet+government services" is the consistent purpose of our party to serve the people wholeheartedly. Serving the people wholeheartedly is the foundation of our party and the source of strength for our party to always maintain its vitality. The CPC Central Committee and the State Council have always attached great importance to serving the people. Promoting "Internet+government services" means taking the people as the center, effectively solving the problems of "too many permits, difficult work, circular proof and wonderful proof", making it easier and faster for enterprises and the masses to do things, and further enhancing the public’s sense of acquisition.

　　(2) Promoting "Internet+government services" is an important way to modernize the national governance system and governance capacity. Accelerating the construction of "Internet+government service" technology and service system in an all-round way is of great significance for deepening the reform of administrative system, transforming government functions, strengthening top-level design and resource integration, promoting government data sharing and business collaboration, and building a government ruled by law, innovative government, clean government and service-oriented government.

　　(C) Promoting "Internet+government services" is a powerful starting point for deepening the "streamline administration, delegate power, strengthen regulation and improve services" reform. At present, the "streamline administration, delegate power, strengthen regulation and improve services" reform needs to be vigorously promoted with the courage of a strong man and the spirit of artisans, and with "greater openness, better management and better service", the transformation of government functions and the release of development potential will be continuously and deeply promoted. However, there are still many weak links in government services, and the innovative model of "internet plus" will become the key direction and an important starting point for the in-depth development of "streamline administration, delegate power, strengthen regulation and improve services" reform.

　　Second, it is imperative to speed up the construction of a national integrated "Internet+government services" technology and service system.

　　This time, the General Office of the State Council, together with relevant research institutions and some local departments, conducted in-depth research and formulated and issued the Guide, designed the national integrated technology and service system of "Internet+government services", put forward the information-based solution path and operation method to optimize the supply of government services, and provided important reference and guidance for various regions and departments to build online government service platforms. At the same time, it is also an active practice to implement the spirit of the important instructions of the Supreme Leader General Secretary on "building a national integrated national big data center".

　　(1) Building a unified business support system based on the standardization of the list of items.

　　It is the fundamental premise for government departments at all levels to carry out online government services and optimize the supply of government online services to sort out government services and re-engineer business processes. Based on the standardized management of the list of items, a unified business support system is constructed. The Guide requires: First, a unified catalogue list. The list of contents is compiled according to laws and regulations, including the basic elements such as the name of the item, the type of the item, the legal basis and the basic code, and does not correspond to the institution. Unified directory list to achieve the same government services at different levels and in different regions, and its basic elements are completely unified. The second is to standardize the elements of the implementation list. The implementing agency of government services will refine and improve the government services in the list of contents, and form a specific implementation list. The elements of the implementation list include 36 full elements, such as event name, basic code, setting basis, event type, implementation code and exercise content. The implementation list is the basis for compiling the government service guide, managing the government service matters and operating the management. The third is to establish a unified event management database. Relevant departments shall dynamically maintain the elements and contents of specific matters according to their respective functions and authorities, strengthen the joint management and application of government service matters, and realize the unification, synchronous update, open homology and multi-use of government service matters data.

　　(2) Building a unified basic platform system with data sharing as the core.

　　Online government service platform is an important carrier to implement "Internet+government service", which mainly realizes the functions of unified application, unified acceptance, centralized handling, unified feedback and whole process supervision of government service. The core of building an integrated online government service platform is to integrate and utilize existing resources and promote data sharing and exchange among government departments. The "Guide" proposes: First, open up the government service platform and business handling system, and connect information on matters, acceptance information, application materials, handling links and completion information to achieve one-stop service. The second is to support cross-departmental, cross-level and cross-regional information sharing, and realize that government service matters can be handled nearby, in the same city and in different places. The third is to promote the docking of the business processing system centrally deployed by the higher authorities and the lower government service platform, reduce the repeated entry of information, and improve the efficiency of government service. The fourth is to realize the sharing and utilization of basic information resources such as population, legal persons, credit information and electronic licenses, and to maximize the use value of data. The national government service platform should undertake the function of access guidance and support cross-provincial (autonomous regions and municipalities) access to national basic information resources.

　　(three) to identity authentication, electronic license, security, etc., to build a unified support technology system.

　　"Internet+government service" is the innovation of government service mode and process. Because of the characteristics of government’s own operating mechanism, it puts forward new requirements for the in-depth application of Internet technology and traditional information technology. Taking online identity authentication as an example, all regions and departments have built independent identity authentication systems in the work of online government services. For individuals, if they want to use the services provided by the government, they must register and verify, and maintaining multiple different user names and passwords has become a burden. For corporate users, it is necessary to register and use multiple certificates and media when conducting electronic bidding and other services across provinces, which also increases the cost. With the in-depth development of "Internet+Government Services", especially for some government services, it is necessary to solve the problem of real-name verification (that is, to prove that registered users are "I am me"), which in turn leads to the security risk of personal privacy data disclosure, and puts forward higher requirements for the functional complexity and security guarantee ability of the identity authentication system. On the basis of summing up the exploration experience in various places, the Guide regulates key technical links such as real-name authentication, electronic license, electronic seal and security, laying a foundation for gradually promoting a unified support and security technical system.

　　(D) to build a unified supervision and assessment system by means of electronic monitoring and third-party assessment.

　　Supervision and assessment is an important means to ensure the implementation of various tasks of "Internet+Government Services". The Guide proposes to adopt the method of "combining internal and external", organically combine internal government supervision with third-party evaluation, and promote the implementation of supervision and assessment. The first is to supervise and inspect the internal operation process of government services by means of electronic supervision. Real-time collection of government service operation data, automatic early warning and alarm for five abnormal situations, such as timeliness, process, content, discretion (charge) and integrity risk point. Open the monitoring result data and accept public supervision. The second is to organize third-party evaluation based on user experience. Around the completeness of service mode, coverage of service items, accuracy of service guide, depth of online service, effectiveness of online service, etc., scientifically set up an online government service evaluation index system to evaluate the supply capacity and service quality of online government service.

　　Third, "three integrations and five spans", give full play to the public foundation supporting role of the national e-government extranet.

　　The core of constructing "Internet+government service" technology and service system lies in information sharing. As a unified government network platform, the national e-government extranet has basically achieved full coverage at the provincial, prefecture and county levels (coverage rates are 100%, 94.6% and 90.6% respectively), and has gradually extended to township streets, horizontally connecting 133 central government departments and related units. At the same time, a unified data sharing and exchange platform for the government extranet has also been initially established. A number of cross-departmental and cross-level sharing and exchange services, such as the national online investment approval platform, the national credit sharing and exchange, and the national public resource transaction, rely on the unified data sharing and exchange platform for the government extranet to operate.

　　In the next step, we will give full play to the role and value of public infrastructure of the extranet of government affairs, strongly support technology integration, business integration and data integration, and realize cross-level, cross-regional, cross-system, cross-departmental and cross-business collaborative management and services.

　　(1) lay a solid foundation. Further strengthen the construction and application of the national e-government extranet platform, and create a new e-government infrastructure with "network access, business access to the cloud, data sharing and unified authentication".

　　(2) One network is connected. Relying on the extranet of government affairs, we will promote the construction of electronic license database and the cross-level, cross-regional and cross-departmental application of electronic licenses, unify the identity authentication system, and build a "one network" for convenience services.

　　(3) Sharing and collaboration. Based on decentralized data sharing and exchange platforms at all levels, we will integrate and establish a nationwide data sharing and exchange platform system, realize multi-level docking and intercommunication between national platforms and local platforms, and promote the smooth flow of government information resources across regions, levels and departments and the efficient cooperation of business.

　　(4) Integrated service. The government extranet will actively participate in the construction of a unified online government service platform, support the integration and construction of a comprehensive service window and an integrated government service system, and form a convenient, fast, fair, inclusive, high-quality and efficient online government service system.

Ride all the way to the battlefield

■ Zhang Naiqian

"Helicopter+motorcycle", can you imagine that this will become a "magic combination" on the modern battlefield? At the Dubai Air Show held not long ago, a UH-60 Black Hawk helicopter displayed by the United Arab Emirates carried an electric all-terrain motorcycle through a special side hitch. According to reports, the "combination" aims to use helicopters to bring the special warfare team into the mission area and complete the rapid assault by riding a motorcycle in the "last mile" of the battlefield.

Riding all the way to the battlefield was once a real historical picture. Whether bicycles or motorcycles, these "small two-wheeled land vehicles" were quickly put into the battlefield as soon as they came out, and a number of classic weapons were successively produced in magic change. Today, we can still see them in the armies of various countries.

In this issue of "Wide Angle of Weapons", let’s look back at the "Hundred Years’ Military History" of bicycles and motorcycles and explore the wonderful past of "going to war alone".

They have a "hundred years of military history"-

The battlefield iron horse emerged.

In the classic French comedy film "Escape from Danger" of World War II, the scene of German soldiers riding military motorcycles and chasing British pilots all the way made people sweat for the brave and tenacious pilots, and at the same time, they deeply realized the unique role of military motorcycles in mobile operations on the battlefield. In another World War II movie "War Day", the Danish army that resisted the German "Armored Corps" turned out to be an army equipped with bicycles.

Look at all kinds of bicycles and bike-sharing now shuttling through the streets. Have you ever thought that their "predecessors" used to be "iron horses in the battlefield"? Since ancient times, the pursuit of flexibility and mobility has been the eternal goal of the armies of various countries. Compared with horses, they need to be fed and carefully cared for. Bicycles are light and flexible to use, do not consume fuel, have low noise and are easy to hide. They can not only transport soldiers, but also cross rugged mountain roads. It’s no wonder that bicycles were quickly favored by armies of various countries after their birth.

On the battlefield of the Franco-Prussian War in 1870, the first military bicycle appeared. Prussian messengers rode bicycles to transmit information and orders on the battlefield, and the French army also sent bicycle squads to frequently penetrate the Prussian rear to spy on information. During the First World War, bicycles became one of the main equipment of the armies of the participating countries. France, Belgium and Britain each have more than 100,000 bicycle troops. Every light infantry battalion of the German Army has specially set up a bicycle company.

During the Second World War, the United States, the Soviet Union and Germany each had their own star "war horse". The American Harley-Davidson WLA motorcycle shines brilliantly on the battlefield, and the Soviet M-72 motorcycle is easy to produce and durable. The BMW R12, R35, R71 and R75 are all favored by the Germans. During the Iran-Iraq War, Iranian soldiers riding motorcycles quickly attacked the Iraqi army’s tank cluster, using rocket launchers, anti-tank grenades and burning grenades to storm the tank forces, and interpreted a unique war history of "motorcycles hitting tanks".

Today, bicycles and motorcycles are still indispensable and important "cars" for soldiers under complex terrain conditions. Regardless of the war in Afghanistan or Iraq, the U.S. military defines bicycles as special auxiliary equipment for Stryker armored vehicles and Hummer off-road vehicles. Once the vehicle breaks down, is destroyed or cannot pass through the terrain, the US military can take out its bicycle and ride all the way to the battlefield. In the open exercise screen of the Iranian Army in 2021, you can also see the scene of soldiers riding motorcycles to quickly launch a battlefield assault.

Not just a means of transportation—

Focus on operations and install "magic change"

At the China International Aviation and Aerospace Expo in 2018, China Aerospace Science and Technology Group displayed the "Cang Lang" missile launching system, which installed a multi-purpose missile launcher on an all-terrain motorcycle. The "infantry assault vehicle" equipped by the Nigerian Army can fully adapt to the local combat environment by installing protective shields and RPK series machine guns on motorcycles, and realize the integration of battlefield mobility and fire assault.

Since bicycles and motorcycles joined the army, they have been used for battlefield maneuvering, improving quick reaction ability, undertaking reconnaissance, vigilance and transportation tasks, and also quickly entered the battlefield "magic change" era with various weapons. British-designed BSA military bicycle has a rifle support clip installed at the seat strut for fixing guns; Italians who dare to "try early" put Maxim’s heavy machine guns on tandem two-seater bicycles; Germany also installed anti-tank weapons and light mortars on TR-FA bicycles. These "machine-gun chariots" react quickly, and the bomb load is not small in the case of multi-vehicle cooperation. They are strange weapons with both offensive and defensive functions on the battlefield.

Compared with bicycles, motorcycles are also a good platform for carrying weapons. During World War II, the Germans equipped heavy-duty sidecar motorcycles with machine guns, carrying several boxes of machine gun bullets and sometimes a light mortar. During the Battle of Berlin in 1945, the Germans used armed bicycles and motorcycles to infiltrate and sneak attack Soviet armored forces and destroyed a number of Soviet tanks.

Another one written in the history of weapons is the German Sdkfz.2 semi-crawler motorcycle. The first half of this motorcycle is no different from ordinary motorcycles, but the second half uses staggered load wheels and crawler-type walking devices, so it is called "Centaur". In 1941, this type of motorcycle was officially put into operation on the eastern front by the German army in the Barbarosa operation, showing its strong passing ability on the muddy road conditions on the battlefield. In fact, whether it is transporting ammunition, pulling artillery, or pulling a few heavily armed soldiers to support the front line, its battlefield performance is remarkable, and the German Air Force even uses it to tow aircraft, which is called the "all-purpose oil" equipment of the Germans on the battlefield.

Get through the "last mile" of the battlefield-

The wheels are rolling and the stage is vast.

With the smoke of World War II dispersed, mechanization and informatization have become the main theme of military development in various countries, and a large number of mechanized equipment have been installed one after another. As "veterans" in the military, bicycles and motorcycles seem to be slowly retiring. In fact, as a portable vehicle that can get through the "last mile" of the battlefield, cycling vehicles still have a broad stage in the modern battlefield.

Rapid force delivery should not be underestimated. As the most "bicycle-loving" army, the Swiss bicycle force was not abolished until the beginning of this century. When you open the map, you can find that Switzerland, which has many mountains and lakes, is a "paradise" for cycling troops. They can cross most mountain roads without fuel and fight in various complex terrain conditions. For this reason, even though the special bicycle troops were cancelled, Switzerland still has not given up military bicycles. Besides exercising physical fitness and adapting to the unique mountain environment, it is also specially used for special forces. Compared with bicycles, armies all over the world still keep a certain number of military motorcycles. Germany’s latest "BMW" F850 GS military motorcycle is a cross-country motorcycle specially used for fast maneuvering.

Folding portability is favored by officers and men. In addition to constantly improving the attack capability, folding and portability has also become the direction of bicycle and motorcycle modification. During World War II, British and German airborne troops were equipped with folding paratroopers’ bicycles. Britain has specially designed Will folding motorcycles for British special operations forces and airborne troops. After the motorcycle is folded and airdropped by a special umbrella bag, it can be unfolded and set off within 10 seconds. In the 1980s, multifunctional mountain bikes and foldable paratroopers developed by the US Department of Defense entered the US military service. The "Paratrooper" folding bicycle weighs 14 kilograms, can carry 150 kilograms, and the length and width of the body are not more than 90 centimeters. The bicycle can be folded or unfolded within 30 seconds. Because it is light and small, the "paratrooper" folding bicycle can be tied to the outside of tanks and armored vehicles, or hung on the paratroopers’ chest to skydive together, giving paratroopers flexible and fast mobility.

Electric silent or become the trend of the times. The electric car has good mute performance, and the sound it makes is even smaller than the voice of people. It can be used for special forces to quickly pass through rugged terrain and launch battlefield raids quietly. The "EZ Rider" electric vehicle being tested by the US Special Forces and the Israel Defense Forces can haul 250 kilograms of materials and travel nearly 40 kilometers on a single charge, which is suitable for special forces. The "Golan" electric off-road vehicle developed by Russia has a top speed of 110 kilometers per hour and a cruising range of 370 kilometers with additional batteries. Russia also specially installed AK-74 rifles, RPG rocket launchers and Grenade launchers for the "Golan" electric off-road vehicle, in order to play an important role in future special forces’ ambush and reconnaissance operations.

On the way back to the classroom after class exercises.

The driver injured a student in school because the brakes were out of control.

Who should be responsible for drivers and schools?

recent days

The Ziyang District Court of Yiyang City, Hunan Province heard this case.

Cases involving campus safety

Please see this case ~

The picture comes from the network.

In February, 2022, when Li delivered the goods to a vocational school in Yiyang by car and returned to the downhill section of the campus, he lost control of the brakes and collided with 17-year-old Song, who was on his way back to the classroom after class exercises, causing Song to be injured. Later, Song was sent to the hospital for treatment, and the medical expenses were 34,176.29 yuan. After identification, Song’s right medial and lateral ankle fracture line involved the epiphysis, which was a grade 10 disability; Multiple fractures of the right foot cause complete destruction of the arch structure of the right foot, which is a grade 9 disability.

Afterwards, Song sued a vocational school, Li and the vehicle insurance company driven by Li to the court, demanding compensation for medical expenses, follow-up treatment fees, hospitalization food subsidies and other losses totaling 296,673 yuan.

After trial, the court held that citizens’ right to life and health was protected by law. If another person infringes upon a citizen’s personal rights due to his fault, he shall bear civil liability for compensation. The vehicle involved in the accident is owned by Li and has been insured with compulsory motor vehicle traffic accident liability insurance. According to Article 43 of the Regulations on Compulsory Motor Vehicle Traffic Accident Liability Insurance, for Song’s loss, the insurance company shall be liable for compensation within the limit of compulsory motor vehicle traffic accident liability insurance, and the rest shall be liable for compensation according to the degree of fault of all parties.

In this case, when driving on campus, Li should ensure the safety of pedestrians, especially on downhill roads, and pay attention to avoiding pedestrians. Li injured Song, who was returning to the classroom because of brake failure, and his fault was the root cause of the accident, and he should bear all the responsibility for the accident; A vocational school failed to fulfill the corresponding obligation of prompting and supervising the vehicles coming to the school. During the dissolution of recess exercise, it should try to avoid the traffic of vehicles on campus, thus inferring that a vocational school failed to fulfill its management responsibilities, and according to the provisions of Article 1201 of the Civil Code of People’s Republic of China (PRC), it was determined that the school should bear 30% of the supplementary liability for compensation.

Based on the above situation, the court ruled that the insurance company compensated Song for medical expenses, follow-up treatment expenses, hospital food subsidies, nursing expenses and other losses of 180,000 yuan within 10 days from the effective date of the judgment; Li compensated Song for medical expenses, follow-up treatment expenses, hospital food subsidies, nursing expenses and other losses of 81,536.99 yuan within 10 days from the effective date of this judgment; A vocational school shall bear the supplementary compensation liability within the range of 24,461.09 yuan when Li can’t pay off the above sum. After the school bears the above supplementary compensation liability, it has the right to recover from Li.

01

The accident happened in a closed campus. Is it a road traffic accident?

This case is a dispute over damages caused by an accident when a vehicle passes outside the road. If a motor vehicle is damaged by a traffic accident, it shall be liable for compensation in accordance with the relevant provisions of the road traffic safety law. Article 77 of the Road Traffic Safety Law of the People’s Republic of China stipulates that accidents that occur when vehicles pass outside the road shall be handled with reference to the relevant provisions of the Road Traffic Safety Law. Article 25 of the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of Laws in the Trial of Road Traffic Accident Damage Compensation Cases stipulates that the provisions of this Interpretation may be applied with reference to damage compensation cases caused by motor vehicles passing outside roads. In this case, Song was injured by a motor vehicle in a non-road traffic accident on campus, and his personal injury compensation can be handled in accordance with the above-mentioned legal provisions.

02

Who will bear the responsibility for the traffic accident on the way to delivery?

According to the provisions of Article 1191 of the Civil Code of People’s Republic of China (PRC), if a student suffers personal injury from an off-campus person while he is at school, the infringer shall bear the responsibility. If the staff of the employing unit causes damage to others due to the execution of work tasks, the employing unit shall bear the tort liability. In this case, a maintenance service co., Ltd. contracted the maintenance and cleaning project of the drainage ditch and septic tank in the male and female dormitory of the school. Li, an outsider in this case, is not a worker or employee of the company, but a deliveryman. Because of his fault, he should bear all the responsibilities.

03

Does the school take responsibility for the accident on campus?

According to Article 1201 of the Civil Code of People’s Republic of China (PRC), if a person without or with limited capacity for civil conduct suffers personal injury from a third person outside the kindergarten, school or other educational institution during his study and life, the third person shall bear the tort liability; Kindergartens, schools or other educational institutions that fail to fulfill their management responsibilities shall bear corresponding supplementary responsibilities. Article 9, paragraph 2, of the Measures for Handling Student Injury Accidents stipulates that if the school safety management system has obvious omissions or management confusion and fails to take timely measures to cause student injury, the school shall bear corresponding responsibilities according to law.

At the time of the incident, Song was a person with limited capacity. During the dissolution of the class exercise, when Li was driving on campus, the school did not have managers to stop reminding him. It can be seen that the school’s safety management was negligent and did not do its due management duties, which caused Song’s personal injury accident. If the school is at fault, it should bear corresponding supplementary responsibilities. After the school assumes the supplementary responsibility, it can recover from Li.

In addition, students are injured from time to time due to construction on campus. During construction, the school should not only educate students about safety, but also make necessary control over related work, always reminding them to pay attention to the safety of teachers and students and create a safe campus environment.

　　CCTV News:The Central Meteorological Observatory predicts that from 28th to 30th, affected by a new cold air, there will be strong winds and cool weather in most areas from northwest to southeast. Autumn and winter are the seasons with high incidence of respiratory diseases. How to prevent them scientifically?

　　Xiamen, Fujian: The number of outpatients in respiratory department has increased significantly.

　　In the past two days, the reporter found in the respiratory clinics of several hospitals in Xiamen, Fujian that many patients were waiting in line for treatment.

　　According to doctors, the number of patients with respiratory diseases has increased by about 30% in the past two weeks, and many of them even come from married with children to see a doctor.

　　Lian Qingrong, Deputy Director of Pediatrics, Xiamen Hongai Hospital:Patients mainly focus on some diseases of respiratory system, and the most common one is actually acute upper respiratory infection.　

　　Beijing: Influenza-like cases increased by 16.69% after the cold wave.

　　Let’s look at the colder north. The results of influenza surveillance by Beijing CDC show that from 15th to 21st of this month, there were 11,689 people receiving influenza-like cases in hospitals above the second level in Beijing, an increase of 16.69% compared with the same period last year. Why has it changed so much? Take a look at the weather before this week.

　　According to the data of China Weather Network, with the arrival of the two cold waves on November 7 and 22, the temperature fluctuation in this month is much larger than that in the same period of last year. Especially in this cold wave that started on the 7th, the temperature difference in one week is nearly 11℃. It seems that everyone should prevent colds before a new round of cooling.

　　Correct distinction: the general symptoms of influenza are obvious, such as high fever and pain.

　　Everyone has respiratory symptoms. How can you tell the common cold from the flu? Experts tell us that the most obvious difference is that the most uncomfortable part of patients with common cold is usually the upper respiratory tract, and once they get the flu, the whole body symptoms will be more obvious.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:The common cold generally does not have obvious systemic symptoms, that is, runny nose, sneezing, phlegm-blocking symptoms, a lot of runny nose, and then there may be throat discomfort, but the flu will be high fever and body aches are very obvious.

　　After the correct distinction is made, how to effectively prevent and treat it? What misunderstandings need to be avoided?

　　How to find the flu symptoms as soon as possible?

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:Now the flu has begun to show signs of epidemic. You may have contacted some people. For example, in such a unit, someone at home has fever symptoms, and then you are infected. At this time, if his infection symptoms are, for example, high fever, chills, even muscle aches and headaches, this is a typical flu performance, which can be basically clarified.

　　Experts said that at present, it is in the high season of influenza, coupled with the need for epidemic prevention and control. If there are symptoms such as high fever, it is recommended to seek medical advice as soon as possible to judge the condition.

　　You can’t carry the flu hard, especially for key people.

　　Because influenza can easily lead to serious complications, people at high risk of influenza, such as the elderly with basic diseases and children with weak immunity, should pay special attention.

　　Hu Shaoming, Deputy Chief Physician of Jialian Street Community Health Service Center, Xiamen City, Fujian Province:Patients with chronic diseases and low immunity will have some serious complications, such as pneumonia, meningitis, or gastrointestinal diseases, which will cause some serious organ failure.

　　You can’t take medicine blindly to prevent influenza.

　　Some people in life often drink cold granules or take other drugs orally after feeling cold or flu symptoms. Experts say that you can’t take medicine blindly to prevent colds.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:You are a high-risk influenza patient. Under special circumstances, this group of people can use some preventive drugs appropriately. For example, there are some effective drugs for influenza, such as oseltamivir, which can be used selectively, but this group must be controlled and not generalized.

　　To prevent influenza, wearing a mask and frequent ventilation are standard.

　　Experts emphasize that vaccination is still the most effective way to prevent influenza. In addition, you should wear a mask and wash your hands frequently. Whether at home, office, school or nursing home, you should always be ventilated.

　　Attending physician Cai Jinghuang, Department of Respiratory and Critical Care Medicine, Zhongshan Hospital affiliated to Xiamen University:For example, if a patient with a cold sneezes here, all his cold viruses are in this room. We should ventilate in time to reduce the concentration.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:Don’t be overtired, keep warm when the weather changes, don’t gather, and maintain your resistance. You eat well and sleep well, so you are also resistant to the flu virus.

What is the flu?

△ Xu Yi, Director of Internal Medicine Department and Director of Infectious Diseases Department of Guangzhou Women and Children Medical Center

Xu Yi, director of internal medicine department and director of infectious diseases department of Guangzhou Women and Children Medical Center, said that influenza, referred to as influenza, is an acute respiratory disease caused by influenza virus and belongs to Class C infectious disease. Influenza A (subtype A H1N1 and subtype A H3N2) and influenza B (strain Yamagata and strain Victoria) are the most prevalent seasonal viruses in the population. Influenza A virus is more likely to spread rapidly among people, and many large-scale outbreaks of influenza in history are related to influenza A virus. Recently, the rising level of influenza activity in many places in China is also caused by the subtype of influenza A (H1N1).

In the past three years, we have taken non-drug interventions, such as wearing masks and limiting social distance, which have effectively curbed the spread of the COVID-19 epidemic. At the same time, it also reduces the exposure to influenza in the population, resulting in the decline of pre-existing immunity in the population, which has a certain risk of influenza epidemic. In the south, there may be a single annual influenza peak from April to June every year.

In the face of influenza virus, we have two sharp weapons to "defeat the enemy": special antiviral drugs and influenza vaccine. As long as you pay attention to personal precautions and maintain good hygiene habits, the possibility of a persistent influenza pandemic is already small, so you don’t have to be nervous and afraid.

How does the flu spread?

Influenza patients and recessive infections are the main sources of seasonal influenza infection. Influenza is mainly transmitted by air droplets, and it can also be transmitted by direct or indirect contact with mucous membranes such as mouth, nose and eyes. It can also spread in the form of aerosol in a crowded, closed or poorly ventilated room.

What are the main symptoms of influenza?

The onset of influenza is urgent, and most of them are self-limited. Mainly with fever, headache, myalgia and general malaise; The body temperature can reach 39~40℃, which is often accompanied by systemic symptoms such as muscle and joint pain, fatigue and loss of appetite. Often sore throat, dry cough, nasal congestion, runny nose, discomfort behind the sternum, facial flushing, conjunctival congestion and so on. Some patients have mild or no symptoms. Mild flu is often similar to the common cold, but flu fever and systemic symptoms are more obvious.

How to distinguish

H1N1 and the common cold?

The child has flu-related symptoms

What circumstances need to be sent to the doctor in time?

1. Persistent high fever > 3 days, accompanied by severe cough, expectoration of pus, blood sputum, or chest pain;

2. Breathing frequency is fast, breathing is difficult, and the lips are cyanotic;

3. Slow response, lethargy, restlessness, etc.;

4. Severe vomiting, diarrhea, dehydration such as less urine and less tears;

5. pneumonia;

6. When the original underlying disease is obviously aggravated.

It should be emphasized that younger children must see a doctor when they have persistent high fever or ultra-high fever in the first 1-2 days of illness, and the antipyretic drugs and physical cooling effects are not obvious, or when they have convulsions.

How to treat the flu?

Generally, children are advised to stay at home and keep the room ventilated after symptoms appear. Get enough rest, drink plenty of water, and the diet should be easy to digest and nutritious. Minimize contact with others and avoid infection. The focus of treatment is to relieve flu-like symptoms such as fever and cough, and the patient’s condition should be closely observed.

Children under 5 years old or obese are more likely to have serious complications, so antiviral treatment under the guidance of a doctor as soon as possible can alleviate flu symptoms, shorten the course of flu and reduce the mortality rate of severe flu.

Remember: antibiotics and hormones are ineffective against influenza virus. )

The flu is coming

How to prevent it scientifically?

1. Personal protection: During the flu season, try to avoid going to crowded places and contacting people with respiratory symptoms; If the child has respiratory symptoms, he should rest at home, conduct health observation, and enter the park and attend classes without illness; Maintain good hygiene habits such as hand hygiene and cough etiquette.

2. Maintain environmental sanitation: keep the residence clean and ventilated, and regularly clean and disinfect key parts such as door handles and handrails.

3. Strengthen the health monitoring of collective units: schools and kindergartens should strengthen morning and afternoon inspections and full-day observation; Children with flu-like symptoms should rest at home to reduce the spread of the disease.

4. Vaccination against influenza is the first line of defense against influenza, and children over 6 months old can have protective effect after vaccination according to recommended procedures. The peak time and duration of influenza activity vary from place to place every year. In order to ensure that the recipients can get immune protection before the flu season, it is recommended to vaccinate as soon as the vaccine is available.

　　"It’s cold, do you want to save something to eat?"

　　"Rice and oil are easy to say. Can vegetables be eaten after a week in the refrigerator?"

　　Epidemic prevention and control has entered a normal state, but many friends have become accustomed to "hoarding" food in the refrigerator — — So, are meat and vegetables frozen or refrigerated? How many degrees is the most suitable for preservation? Can I eat it after a week?

　　Meat should be "cold" and vegetables will be "frozen"

　　The bought fish can’t be kept, and the vegetables will rot in the refrigerator for a few days. Is the meat taken home refrigerated or frozen … … "hoarding goods" not only makes the elderly scratch their heads, but also makes the young people confused.

　　"Generally speaking, the requirements for the preservation environment of various foods are different, and it is definitely not possible to stuff them all into the refrigerator." According to industry insiders, in professional supermarkets, the storage temperature of all kinds of foods is relatively fixed; Consumers pick and choose and take them home and stuff them into the refrigerator, often only to find that they have gone bad when they eat them.

　　"If you go to a big supermarket like Metro in summer, you may have to bring a thick coat to the meat sales area." The reporter learned the "best storage temperature" of different foods in Metro: frozen products are at-18℃ ~-22℃, cold meat is at 0-4℃, fish is at 12-16℃, and fruits and vegetables are at 12-14℃; Therefore, even in summer, the area where meat products are sold is very "frozen". The person in charge of the Metro member store said: "Different foods require different storage temperatures, and only by taking correct temperature control measures can the freshness, hygiene and safety of foods be guaranteed."

　　In general, the freezing temperature of household refrigerators is -18℃, while that of cold storage rooms is 0-4℃. Therefore, the cold meat bought home can be stored in the cold storage room if it is eaten soon, and there is no need to freeze it. In the current weather, fruits and vegetables don’t have to be put in the refrigerator when they are bought home. They can be stored at room temperature and eaten as soon as possible. It should be noted that even frozen food should be eaten within 90 days; The flavor and nutritional value of foods frozen for too long will be greatly reduced even if they are not "spoiled".

　　Constant temperature in the whole process is very important, and "thawing and freezing" is not advisable.

　　If you buy too much meat and freeze it, take it out and cut it, and put the rest back, okay? The answer is: no.

　　"Frozen food is easy to breed bacteria during repeated thawing and freezing." Nutrition experts said that some institutions have done relevant comparative tests, frozen and thawed the same piece of meat for four times, and carried out bacterial inspection every time. The results showed that the total number of colonies increased sharply after thawing and refreezing, and the total number of colonies in the last time was 15 times that of the first inspection.

　　The reason is that food will inhibit the growth of bacteria when it is frozen at low temperature, but in the process of thawing, with the increase of external temperature, bacteria in food will multiply rapidly; When we put the food in the refrigerator again, the low temperature environment can inhibit the growth of bacteria, but it can’t "kill" the bacteria that grew before. When it is thawed again, the bacteria will double.

　　"Big supermarkets can guarantee the ‘ of purchasing, processing and sales areas; Whole cold chain ’ But often consumers don’t care after buying it back, which will lead to food deterioration, "nutrition experts pointed out." Therefore, fresh products should be put into the freezer immediately and frozen products should be put into the freezer as soon as Metro, a supermarket that takes a "whole cold chain" approach to meat, comes home, keeping the "last link" still in the cold chain.

　　If you can’t eat it all at once, it is recommended to freeze it in small pieces and thaw as much as you eat. Whether consumers purchase frozen products or fresh ingredients themselves, it is better not to "thaw twice" after freezing. Zhang hongmei
