Navigator China-Implementing a healthy China strategy to safeguard people's health from the source

Navigator China-Implementing a healthy China strategy to safeguard people's health from the source People's health is an important symbol of socialist modernization. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping as the core has adhered to the people-centered development concept, put people's health in the strategic position of priority development, and continued to deepen medical and health care. System reform, continuous improvement of the health and health system, my country's health and health undertakings have moved from "treating diseases as the center" to "people's health as the center, efforts to protect people's health in all directions and in all cycles. At the Chronic Disease Management Center of Shaxian District General Hospital in Sanming City, Fujian Province, the system is dynamically analyzing and evaluating the health data of more than 100,000 residents in the district, and conducting differentiated management according to the condition. Hong Zhengu, a villager from Shankou Village in Gao Qiao Town, was included in chronic disease management three years ago. Due to unstable blood pressure, Hong Zhengu became the key nursing object of rural doctors after systematic early warning. In addition to visiting the village, he also issued diet and exercise prescriptions. Hong Zhengu, a villager in Shankou Village, Gaoqiao Town, Shaxian District, Sanming City, Fujian Province: Now that the government's policy is so good, we just enjoy it and protect our bodies. In recent years, we have few opportunities to go to the hospital. Today, 11 districts and counties in Sanming have set up general hospitals, set up such chronic disease management centers to carry out health management and monitoring of residents, and a health security system for everyone is being built. From the fact that the medical insurance fund is unsustainable to the accumulated balance of more than 2 billion yuan, Sanming Medical Reform in the past ten years pointed out that the prices of drugs and consumables were inflated, and the medical insurance fund wasted a huge "stubborn disease" in the medical system. By eliminating the use of drugs to support doctors and squeezing out the water from the price increase, the expenditure on medical consumables has been reduced by more than 15.8 billion yuan in the past ten years. At the same time, the income distribution system of hospitals and doctors, increase the sunshine income of medical staff. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping as the core has always put people's health in the strategic position of priority development. In March 2021, General Secretary Xi Jinping came to the Shaxian District General Hospital of Sanming City to learn about the situation of medical reform benefiting the people. At that time, in the outpatient hall, Weng Hua, a teacher in Shaxian District, showed the General Secretary his medical insurance account, which still had a balance of more than 10000 yuan. Weng Hua, a resident of Shaxian District, Sanming City, Fujian Province: the general secretary also asked, that is to say, why there is a balance in the (medical insurance account). I said that one is that the proportion of reimbursement has increased. The starting line for the second individual is lowered, and the third drug is very cheap. Last year (balance) 10000 a little more, this year (balance) has 13,000 more, this is more than last year (balance). Without universal health, there is no comprehensive well-off. The Party Central Committee with Comrade Xi Jinping at the core made a major decision to "promote the construction of a healthy China" at the Fifth Plenary Session of the 18th Central Committee. At the first National Health and Health Conference, it was clarified that "the treatment of diseases is the center. The national health and health work policy for the new era is centered on people's health. From the release of the "Healthy China 2030" Planning Outline "to the report of the 19th National Congress of the Communist Party of China to make comprehensive arrangements for the" Implementation of the Healthy China Strategy ", the top-level design, overall strategy and implementation path of the construction of a healthy China have been continuously clarified. This decade has been a decade in which the reform of China's medical and health system has continued to deepen and the problem of difficult and expensive medical treatment for the people has been solved at an accelerated pace. China has historically completely broken the system of replenishing medicine with medicine, and continuously promoted the transformation from "taking treatment as the center" to "taking people's health as the center. The problem of people's difficulty in seeing a doctor has been effectively alleviated. The three-level medical and health service network covering urban and rural areas has been continuously improved, and 90% of families can reach the nearest medical point within 15 minutes. The problem of expensive medical care for the masses has been alleviated. The national list of essential drugs has increased to 685 varieties. The number of people participating in basic medical insurance exceeded 1.36 billion, and the proportion of residents' personal health expenditure in total health expenditure fell to 27.7 per cent, the lowest level in 20 years. Xu Shuqiang, Director of the System Reform Department of the National Health Commission: The implementation of the Healthy China Strategy by the Party Central Committee with Comrade Xi Jinping at the core is a pioneering work to safeguard the health of the people from the source. We must unswervingly deepen the reform of the medical and health system and continuously improve the quality of medical services.

Zhang Liming: Innovation Mends Work Happier

Zhang Liming: Innovation Mends Work Happier "A mobile charging gun covers 6 parking spaces. If 5 are installed, 30 parking spaces can be covered." In the innovation studio, Zhang Liming, a representative of the 20th National Congress of the Communist Party of China and the monitor of the power distribution repair class of the State Grid Tianjin Electric Power Binhai Power Supply Company, sat around and discussed with two engineers and technicians. The pile of paper beside him was covered with design sketches. During the discussion, Zhang Liming introduced his latest idea-"mobile shared charging pile" to reporters ". "when carrying out electric volunteer service, I found that the demand for charging piles at the grass-roots level was increasing, so I thought of setting up fixed charging piles, coupled with movable charging guns, to meet the green travel needs of more people as much as possible." "Strive to achieve more high-level intelligent results on the road of innovation." In the prominent position of the innovation studio, Zhang Liming wrote this sentence. This is a true portrayal of his commitment to innovation and forge ahead for more than 30 years. Zhang Liming and his colleagues are debugging the fourth generation of live working robots for distribution networks (photographed on September 8, 2022). Photo by Xinhua News Agency reporter Zhao Zishuo Zhang Liming said that from the first day of his work, the master repeatedly told him, "rush to repair work, 'robber' is time, 'repair' is technology". In long-term practice, Zhang Liming has trained the "golden eye" of power emergency repair, which can quickly and accurately judge the cause of the fault and confirm the fault point according to the scope of power outage, weather conditions and line conditions, so as to strive for precious time for timely restoration of power transmission. The utensils are tangible and the ingenuity is unbounded. High-voltage knife gate new protective device, can be removed type low-voltage knife gate ...... In August this year, the World Conference on the development of vocational and technical education, Zhang Liming with these years of innovation results exhibition, to show the world the wisdom of Chinese workers. "Although I only Secondary specialized school academic qualifications, as long as I establish the belief of lifelong learning, I can achieve results." Zhang Liming said. Zhang Liming (left) and his colleagues are debugging the fourth generation of live working robots for distribution networks (photographed on September 8, 2022). Photo by Xinhua News Agency reporter Zhao Zishuo The innovation studio is equipped with the "fist product" led by Zhang Liming-the fourth generation of live working robots for distribution networks. Although China has realized the machine instead of workers to carry out high-altitude live work, can repair workers also need to carry out high-altitude assistance. Aiming at the goal of being smarter and lighter, Zhang Liming has repeatedly tested and modified in the past few years, and the fourth-generation robot has finally come out and realized industrialization, and has been extended to 20 provinces. "Work is happy, and innovation makes work happier." Zhang Liming often puts this sentence on his lips and encourages more young people to innovate. At present, Zhang Liming's innovation position has become a base for cultivating innovative talents, leading 63 innovation studios and more than 2000 "power makers" and "blue-collar makers" to achieve fruitful results. The Communist Party member service team named after Zhang Liming has developed into a normalized social volunteer service organization composed of 30 teams and more than 400 members, and has been rated as the "National Demonstration Site for Learning from Lei Feng". Zhang Liming (right) led the State Grid Tianjin Binhai Liming Communist Party Service Team to check the electricity meter for residents in Dandongli Community, Binhai New Area, Tianjin (taken on July 15, 2022). Xinhua News Agency (Photo by Li Jin) Over the past few years, Zhang Liming has always been on the front line of emergency and danger. In early 2021, the new coronary pneumonia epidemic in Hebei Province appeared repeatedly, Zhang Liming took the initiative to invite Ying, leading 17 team members to set up an "anti-epidemic power protection commando", starry night rushed to Hebei; last July, he went to Henan to support the anti-flood. "I feel honored and sacred to be elected as the representative of the 20th National Congress of the Communist Party of China." Zhang Liming said that the comprehensive construction of a modern socialist country is inseparable from innovation. We must adhere to the goal of "building an army of knowledge-based, skilled, and innovative workers", based on jobs, and unswervingly follow the path of innovation.

Dry grinding and water grinding, what is the difference between these two grinding methods

Dry grinding and water grinding, what is the difference between these two grinding methods In the construction process of floor grinding machine, there are two kinds of grinding methods, and what are the advantages and disadvantages of each, Qing Qin Yu will explain them to you one by one. 1. dry grinding Advantages: 1. The work efficiency should be higher, dry grinding does not need to sprinkle water and collect water in every process, which is more convenient and very time-saving; 2. Grinding effect is better, dry grinding equipment is generally large concrete ground grinding machine, heavy weight, good cutting force; 3. Visual identification ability, dry grinding is more conducive to the observation of ground grinding, to avoid grinding errors without knowing; 4. construction of high quality, dry grinding out of the ground more delicate, gloss will be better. Disadvantages: 1. Dry grinding on the ground more shallow, but also more prone to scratches; 2. Dry grinding dust is large, harmful to human health, need to be equipped with professional dust removal equipment to achieve dust-free grinding.

Looking at "China's Vitality" in the Data and Feeling China's Economic Kinetic Energy from "Excavator Index"

CCTV news: continue to look at the data in the "China vitality" series of reports. Today (September 26) is the excavator index. This index shows the operating rate and working conditions of all kinds of construction machinery and equipment, and is known as "the barometer of China's economy". According to data from the Ministry of Industry and Information Technology, the overall operating rate of construction machinery nationwide in August this year was 63.99 percent, and the average operating rate so far this year has exceeded 60 percent. National Industrial Internet Big Data Center Data Institute Li Haowei: Overall, although our country as a whole this year has been affected by some outbreaks, but the state of construction machinery operation is still in a relatively steady growth state. From a regional perspective, from January to August this year, the construction enthusiasm of many provinces in the northeast, northwest, and southwest maintained growth. With the introduction and implementation of the economic stabilization package policy, the overall machinery operating rate of 17 provinces and cities achieved a positive month-on-month growth in July. Jilin Province even set the highest national operating rate of 78.01 in August this year. In addition to infrastructure construction, in construction machinery and equipment, front cranes and stackers are used for container loading and unloading in ports, which are closely related to import and export trade. The provinces and cities with active foreign trade this year are mainly concentrated in the southwest, central China, northeast and other regions, and many inland provinces and cities have performed well. In August, the operating rate of port equipment in Sichuan Province reached 88%, the highest this year. The high level of the "excavator index" shows that the efforts of macro-policy to carry out infrastructure investment ahead of time have achieved remarkable results. At present, from the central to the local level, specific arrangements have been intensively implemented to accelerate the construction of new infrastructure while improving the level of traditional infrastructure. In Ningxia, the country's largest desert photovoltaic base-Tengger Desert 3GW new energy base photovoltaic compound project held a groundbreaking ceremony a few days ago. As a key supporting project of the "Ningdian into Hunan" project, the total installed capacity of the project is 3 million kilowatts and the total investment is 15.25 billion yuan. In Hainan, Haikou City has just held the third batch of major projects in 2022, with 30 projects with a total investment of 17.39 billion yuan, with a planned investment of 3.05 billion yuan this year. Since the beginning of this year, the construction of 102 major projects in the "14th Five-Year Plan" has been continuously accelerated, and more than 2600 projects that have been separated have been implemented in a safe and orderly manner. Su zimeng, President of China Construction Machinery Industry Association: throughout this year, I think the construction machinery industry should be in a stable operation state, and the export should have a rapid growth. A series of major equipment on the market, it should be said to meet the needs of the national (economic) construction of various key projects. Recently, my country's policy-based development financial instruments have continued to expand. The State Council executive meeting held not long ago made it clear that on the basis of 300 billion yuan of policy-based development financial instruments that have fallen to the project, the amount of more than 300 billion yuan will be increased. The renovation of old neighborhoods and provincial highways will be included in the areas of support; the local special debt limit of more than 500 billion yuan since 2019 will be activated in accordance with the law, with 70 per cent retained in various places and 30 per cent allocated by the central government as a whole and tilted towards areas with more mature projects. It will focus on supporting transportation infrastructure, energy, agriculture, forestry and water conservancy, ecological and environmental protection, social undertakings, urban and rural cold chain and other logistics infrastructure, municipal and industrial park infrastructure, major national strategic projects, affordable housing projects, new energy projects and new infrastructure project construction. The construction of major projects is in full swing, stimulating investment, but also constantly stimulating the development of China's construction machinery industry. In recent years, many major equipment in our country have made historic breakthroughs, such as 4000-ton crawler cranes, 2000-ton all-terrain cranes, and hydraulic excavators with more than 100 tons. Construction machinery and equipment continue to move towards the middle and high end. Next, let's go to see a domestic "Big Mac"-currently the largest tonnage crane in China. Its lifting weight can not only reach 4500 tons, but also can do fine work accurate to millimeters. Not long ago, at the refining and chemical integration construction site in Longkou, Shandong Province, a reactor with a height of 32.7 meters and a weight of more than 1400 tons was hoisted to a designated location. The hoisting equipment is currently the largest 4500-ton crawler crane in China. Although they are all huge objects, the hoisting position is accurate to millimeter level. Zhang Yang, deputy dean of an equipment research institute: Our car is equipped with various sensors. Move a handle, it can move a little bit to ensure that we will not have an impact on the hole at the end. Large tonnage cranes are expensive and have a long production cycle, and have been dependent on imports for more than a decade. In the process of more than 10 years of research and development, the scientific research team has cooperated with many domestic universities to use digital prototypes to conduct repeated trial and error experiments. Zhang Yang, deputy dean of an equipment research institute: We have made a digital prototype, which is equivalent to a physical machine, and we have made it exactly the same on the computer, including the construction of all electromechanical and hydraulic power systems, and then joint simulation. After more than ten years of continuous trial and error, domestic large-tonnage cranes can finally show their talents in the construction of major projects. They not only have the heaviest lifting tonnage in the world, but also can deform. The herringbone system has a wide bottom and a narrow top, which not only improves the stability of the crane, but also can disassemble 4500 tons into two 2000 tons that operate independently. The modular design not only meets the lifting requirements of various weights of the construction parties, it can also save the cost of loading and unloading, transportation and other links of the crane. In addition, before the construction, the enterprise will also carry out "tailor-made" according to the needs of each engineering operation to ensure the safety of the project. At the same time, the material production of crane parts will gradually realize localization, reduce manufacturing costs, and drive upstream and downstream enterprises to work together. Zhang Yang, vice president of an equipment research institute: we cooperate with well-known steel mills in China. One is steel plate and the other is steel pipe, which can be delivered in three months. We have been building a crane for less than a year now, and the cost has been reduced by half. (Now) steel mills have begun to export the steel we use to foreign countries.
