Multiple mechanisms reduce inflammation, and millions of people around the world are deeply troubled. This chronic disease is expected to usher in a new inhibitor.

Inflammatory bowel disease (IBD) is a chronic disease that affects more than 6.8 million patients worldwide, mainly manifested as Crohn’s disease and ulcerative colitis. Patients suffer from abdominal pain, diarrhea and other symptoms for a long time. Because of its complicated pathogenesis, including heredity, environmental factors, intestinal microbial imbalance and abnormal activation of immune system, there is no radical cure at present, and traditional drug treatment has side effects and some patients have poor response. In a recent study published in Biomedicine & Pharmacotherapy, scientists screened a candidate molecule named KB-0118, which is expected to be used in combination with existing drugs to provide a more efficient and safe treatment scheme. BET family proteins play a key role in gene transcription regulation and have been used in tumor treatment before. However, the application of traditional pan-BET inhibitors is limited because of their high toxicity and short half-life, so the development of new BET inhibitors has become a hot research topic at present. This discovery provides a new hope for the treatment of IBD and other inflammatory diseases.

Investigation | "Medical Q&A" has a routine!

Original xinchao xinchao

Recruitment of part-time medical questions and answers, the answer is found online, earning at least 80+ a day, and recruiting a lot of people!

Part-time job of medical question and answer is simple and easy to operate, one question in a few minutes, and the daily income is hundreds. The more you do, the more you earn!

Typing the keyword "Medical Q&A" on Baidu, I found that similar recruitment information exists in a large number of forums such as Post Bar, Douban and Zhihu, and there are not a few applicants who reply to it. What is this repeatedly mentioned part-time job of medical Q&A?

Part-time medical question and answer without threshold

"Our part-time job is to do medical questions and answers on a website, search from Baidu according to the prescribed title, and improve it as an answer." According to a job advertisement on Douban, the reporter added the QQ of the recruiter and asked about the information about the part-time job of medical question and answer.

This kind of part-time job is online part-time. Applicants only need to have typing ability and a mobile phone or computer as working equipment. Due to the low barriers to entry and the great demand for jobs, it has become a popular choice for online part-time jobs. Most of them are students and unemployed people, most of whom have a low education level.

According to the recruiter, the daily income of the medical part-time job is 100 yuan to 200 yuan, and the salary is calculated according to the daily workload, so the more you work, the more you get. Answer a question, the income ranges from 0.4 to 0.8 yuan, and the highest income does not exceed that of 2 yuan. Different types and difficulty questions have different prices.

Self-questioning and self-answering workflow

According to the recruiter’s operation guidance on QQ, the applicant must first register an account on a specific website according to his specified name and invitation code, and then he can join the group, conduct induction training and assign work tasks after registration is completed.

Chat history with recruiters

According to the website provided by the recruiter, the reporter entered a website named "Pineapple Crowdsourcing", which calls itself "the leading big data content customization service provider in China", and its business includes but is not limited to pictures, texts, audio and video, ai collection, offline scenes, etc., but its main business is still "medical question and answer" service.

Click "Start Work" in the center of the webpage to enter the work page. There are many published tasks on the page, but you can only choose the projects that your team has joined. If the team has not joined, only individuals cannot participate.

Click one of the team tasks to start work. The specific work page is as follows:

Work page of pineapple crowdsourcing website

From this work page, it can be seen intuitively that part-time medical question-and-answer workers need to play the roles of patients and doctors at the same time. According to the reference title, draw up your own topic, describe the problem in the first person, diagnose and analyze the problem in the doctor’s tone, and put forward corresponding suggestions.

How do non-professionals "write" the answer?

The recruiter said, "The answers are searched from Baidu, and then improved." Most of the answers to "medical questions and answers" are searched from Baidu, and the authoritative answers to related questions are taken as reference standards, such as Dr. Lilac and Dr. Good Doctor, from which multiple answers are copied, then pieced together and integrated, revised according to the corresponding revision rules, and the final answers are obtained, and then pasted on the work page to complete the self-questioning and self-answering process.

Surprisingly, this kind of crowdsourcing website also has a duplicate checking tool. After revising the copied answers, it is necessary to check the duplicates on the homepage of the website. The duplicate checking tool will display the percentage of originality. If the answers exceed a certain percentage, they will be judged as unqualified data, and they will not be submitted successfully on the work page, which is invalid data, and part-time workers will not get commission.

In addition to the "self-duplicate checking" process, the platform will also double-check the data submitted by part-time workers in the background of the website to ensure that the repetition rate is less than 30%.

Duplicate checking tool of pineapple crowdsourcing website

How to write a "qualified" question and answer?

It is necessary to use the collected authoritative answers as a template and reduce the repetition rate. How to coordinate the two? To solve this problem, the part-time group provides reference templates and revised requirements for non-professionals to help them get started quickly and complete the medical question-and-answer tasks that meet the requirements. These files are uploaded to QQ group files, and novices are required to carefully review these files as part of the induction training.

In the group file department, several template files are published, which are the reply templates of common diseases such as cervical spondylosis, fracture and cosmetic sequelae, and list the main points of reply and suggestion. In addition, there are dozens of documents about the attention requirements of compiling "medical questions and answers", including the wording, symbols and sentence requirements in questions and answers, as well as the content precautions.

Part-time QQ group file

The seemingly simple and easy-to-operate medical question and answer has many details behind it. In terms of wording, it is necessary to delete colloquial useless expressions, such as "suggestions", "according to your situation" and "wish you health", and at the same time, punctuation needs to be unified, and it is also required that two uncertain words cannot be used continuously in the sentence pattern.

In addition to formal requirements, medical questions and answers also have high requirements in problem description. First, the designed condition must be reasonable and cannot deviate from the theme; Second, and most importantly, part-time medical question-and-answer workers must ask questions from the perspective of the first person, that is, the patient, and describe the illness in detail around the title, including basic information, main illness, historical diagnosis, etc. At the same time, in the question, no specific place names can appear, and no treatment price can be involved.

In medical questions and answers, the requirements for answering questions are the most complicated. You can’t make common-sense medical mistakes in imitating doctors’ answers, and you can’t just say cliches in order to avoid mistakes. The most important point is that you can’t have specific drug names. Even if the title asks "What medicine do you need to take?", you can’t directly prescribe prescription drugs, and you can only use antibiotics, antiviral, anti-inflammatory and anti-stress drugs instead. At the end of the answer, it is necessary to explain the precautions to the patient. It must be an immediate suggestion for the patient’s current disease, but the wording should be euphemistic. You can’t directly give a detailed treatment plan, and try not to write suggestions about diet.

A highly identical answer

By referring to the template file and comparing with the standard file, it is much less difficult for non-medical professionals to write "qualified" answers, but do these medical suggestions written according to the template have practical guiding value?

The reporter copied the template answers about "how to treat lumbar muscle strain" in the group files, and searched in Baidu, and several highly similar answers appeared, including "Thumb Doctor", "39 Health Network", "Ask the doctor quickly" and "Baidu Experience". Unexpectedly, one of the patients and the doctor had many interactive questions and answers, and the doctor’s answer was actually the result of pasting and copying.

Template answers in group files

The same answer of Baidu search

In addition, the author also searched for reference answers in template files such as "lymph node enlargement", "fracture" and "side effects of injection of hyaluronic acid", and all of them can find highly similar language segments and even similar voice reply segments on Baidu. These paragraphs appear in different medical websites and Baidu Q&A, with different questions and descriptions, but with different answers. Some answers even haven’t changed a word, and they are completely copied. This kind of consultation does not suit the right medicine, it is difficult to talk about authority or not, and it is extremely irresponsible to patients.

The author found that the appearance time of these questions and answers about seeking medical treatment on Baidu was concentrated after 2015, and the peak time was in 2018 and 2019, which were earlier than the release time of the template file. To some extent, this shows that the medical question and answer industry chain has been popular for many years, and the template answer has been applied for many years, so it is difficult to find out the source.

Essentially "manuscript washing" behavior

In order to have enough content data in the early stage of establishment, some websites and apps will artificially produce data in the form of "data management", and "medical question and answer" is a typical example. Recruit part-time workers and compile medical questions and answers that meet the "standard", and the way of compilation is to copy and paste and then modify them, so as to change the word order, use words and add or delete them through the website audit, but the content produced by a template, no matter how modified, will eventually get the same answers.

Not involving prescription drugs, lack of detailed treatment plans and less dietary advice are typical characteristics of medical questions and answers. At the same time, most of these "medical questions and answers" are answers to specific and common diseases, focusing on "how to do it" rather than "what is it", that is, the name and cause of the disease will not be judged according to the description of symptoms, and the answers are not targeted, and they will not prescribe the right medicine according to the specific situation of the patients, but "scratch the ball" and confuse the eyes with general words. It seems that the reply on the tall is actually the "pseudo original" data set early.

"False" interactive question and answer between doctors and patients

In essence, "medical question and answer" is a veritable "manuscript washing" industry. In the Internet age, people are used to surfing the Internet to find countermeasures when they are unwell, and medical questions and answers came into being. Today, robots can be used in voice question and answer. Who can guarantee that the respondents of online diagnosis are professional doctors? Perhaps, the opposite is just a cold template, which has already been done, waiting for the unknown routine to "take the bait".

Pseudo original’s medical questions and answers aggravated people’s distrust of online consultation. The mixed information is fascinating, and people can’t tell whether the answer they refer to is the professional reply of the doctor or the "self-question and answer" of the part-time medical question and answer.

Huawei Digitalization: From China Manufacturing to China Creation

Author Wang Yi

Produce a digital newspaper

When people think of Huawei, most of the labels they think of are made in China, chips, HarmonyOS, Huawei Cloud and so on.

Since its establishment in 1987, it entered the Fortune Global 500 for the first time with the ranking of 397th in 2010, becoming the only Fortune Global 500 company that has not been listed. By 2021, it has become the 44th Fortune Global 500 company and a giant that has been admired by China and even the world. The rapid rise of Huawei has attracted worldwide attention.

From the standpoint of reality, Huawei is indeed a successful enterprise. But when it was first established, it was just a small company in a dilapidated factory building in Shekou, Shenzhen, with a registered capital of only 21,000 yuan, and its main business was telecom equipment trade.

For more than 30 years, Huawei, like other enterprises, has been lost on the road of digital transformation; Different from other enterprises, in the current digital age, Huawei is no longer the enterprise that is struggling to walk on the road of digital transformation, but has turned into a "guide" on the road of digital transformation.

In 2018, Huawei followed the pace of the times and upgraded the company’s mission vision to "bring the digital world to everyone, every family and every organization, and build a smart world with the Internet of Everything".

Today, Huawei Cloud has become the second largest cloud service provider in China, and has become a solid base and assistant for the digital transformation of enterprises. From 20,000 yuan to trillions of market value, from a "second-hand trafficker" to a multinational giant, from a lost person on the road of digital transformation to a guide on the road of digital transformation, this role change is driven by Huawei’s own transformative power, and it is also a perfect answer sheet handed over under its digital transformation.

In the development of Huawei, digital transformation plays a very significant role in its important development period.

In essence, Huawei is a traditional enterprise. Unlike the BATZ Internet giant, Huawei itself has no genes of the Internet, and it has explored its own digital road step by step from traditional enterprises. Practice produces true knowledge, and the practical path of successful digital transformation is always much more useful than "digital experts" on paper. The experience of Huawei’s digital transformation is worth learning and learning from all enterprises.

So, how did Huawei put the digital transformation to the ground? What is the relationship between Huawei’s success and digital transformation?

First, informatization, the establishment of a fast runway

In 1987, Ren Zhengfei and five partners jointly invested 20,000 yuan to establish Huawei. During this period, Huawei mainly adopted the following strategy in product development strategy, first acting as an agent for products of Hong Kong companies, and then gradually evolved into a centralized strategy for independent product development. In the market competition strategy, we adopt the sales strategy of continuous development and production of a single product and encircling the city from the countryside, seize the market quickly through low-cost ways, expand the market share and expand the scale of the company.

1987-1997 was a period of strategic transformation for Huawei from "trade technology" to "technology industry and trade".

In 1991, Huawei began to design its own chips based on the demand of products. In 1992, it invested tens of millions of yuan in research and development. At the end of 1993, it successfully made the first chip, namely ASIC chip for C&C08 switch.

In 1994, Huawei successfully designed more than 30 chips. Among them, the most complex chip design accommodates more than 10 million transistors, and each chip can complete 32,000 telephone users’ non-blocking calls.

In this process, Huawei’s customers and businesses are all in China. With the increase of business volume, the management system can’t keep up with the development needs. So in 1992, Huawei began to develop its own management information system to replace the traditional manual business process, thus realizing local business automation.

At the same time, Huawei recognizes that introducing mature IT products and technologies to implement IT solutions can reduce investment risks and shorten the return period of investment. The complexITy of enterprise management software makes enterprises rely on their own strength to develop, which is very uneconomical in time, personnel and financial resources, so it is necessary to adopt the strategy of "introduction and management" to implement IT solutions.

So in 1994, when the local small application software independently developed by Huawei could no longer support the business, Huawei began to build the MRPII(Manufacture Resource Plan) system, that is, the manufacturing resource plan. It is a planning and control mode of production management, which is regarded as a standard management tool because of its remarkable benefits and is widely adopted by the world manufacturing industry.

Huawei finally chose the MRPII product of Oracle in the United States through software inspection and selection. Huawei is the first enterprise in China to adopt MRPII management mode, one or two years earlier than Lenovo. Lenovo’s MRPII system and OA system were built in 1996.

In 1995, Huawei OA system began to be built. At the end of the same year, Huawei introduced NOTES groupware system.

NOTES groupware system connects different users, especially users in different departments within the enterprise, through the network, thus improving the production efficiency. E-mail is a function of groupware, which encourages users to communicate and coordinate activities with each other. All users who enter the groupware system can communicate with each other in a timely and interactive manner, and transmit various messages, such as sound, graphics and video images.

In 1996, as the earliest user of ORACLE MRPII software in China, Huawei launched version R10.6, selected 13 core and basic functional modules, and realized "financial and business integration".

According to the independence of MRPII application system business, Huawei’s MRPII application system is divided into seven application environments: Huawei running environment (HW-CRP), Xinhua running environment (NHW-CRP), ring communication running environment (GT_CRP), Hong Kong Huawei running environment (HKHW-CRP), Huawei communication running environment (MBC-CRP) and Huawei testing environment (HW-CRP).

Huawei’s implementation of MRPII is very effective. At the initial stage of introduction, MRPII method has been applied in departmental business. For example, in the production planning management, according to the principle of MRPII, rolling backward and material demand analysis methods have been adopted, and good results have been achieved. The turnover rate of production inventory has increased from 2 to 3 times in the past year to 5 times.

With the comprehensive application and practice of MRPII timely production and process optimization, the production cycle of exchange equipment has been reduced from one month in the past to half a month.

In 1996, Huawei established the intranet and central database, and formed many new working methods on the basis of it. Advanced information technology makes Huawei’s operation more efficient. Employees and departments can communicate and exchange needed goods by visiting each other’s databases, web pages and bulletin boards.

It is more convenient to collect, archive and manage information, and it is very fast to retrieve and consult. The flow of information in an organization has become very rich, accurate and timely through the internal Internet.Convenient information collection and dissemination has improved Huawei’s organizational innovation and responsiveness, and the middle layer has been cut, which makes it possible to flatten the organization.

Through the first stage of information construction, Huawei’s business development bid farewell to inefficient manual work and established an information fast runway. The advantages of management informatization have laid the foundation for Huawei’s future electronic process management and full integration with IT.

Second, IPD went online and headed for "customer-centric"

In 1997, Huawei’s sales revenue was 4.1 billion yuan, ranking among the top 10 in China’s top 100 electronic companies, with more than 5,600 employees.

Some hidden problems are gradually exposed.

"When I first started my business, I was actually alone, and then some people kept coming in. There were no rules at all. For example, if I say, "How much salary do you get?", it’s settled. Of course, it will benefit some people and hurt some people. With the growing size of the company, it is necessary to draft a lot of documents to standardize the company, but I have no ability to draft documents. Personally, I am engaged in technical work in the army and have never been engaged in management work. However, we have to move forward, so we have drafted many documents, but we feel that these documents are not standardized, which is not conducive to Huawei’s growth into a big company. " Ren Zhengfei said.

In terms of R&D, Huawei didn’t have a mature R&D process and decision-making mechanism at that time, which led the marketing department to promise customers’ needs at random, and the R&D department was in a hurry to cope with it, and the products made were repeatedly revised. At one time, the company’s product version number was more than 1,000, which was chaotic in management and extremely inefficient.

One set of data is that Huawei invests 10% of its sales in product research and development every year, but the waste ratio of research and development expenses and product development cycle are more than twice the best level in the industry. Although Huawei’s sales have increased year after year, its gross profit margin has decreased year by year, and its per capita benefit is only 1/3 to 1/6 of that of Cisco and IBM.

Huawei awarded the "Golden Raspberry Award" to the R&D department and product line at the annual summary meeting of 10,000 people one year. Many products that were designed by R&D but not recognized by the market and directly turned into dead materials in the warehouse were sent to the R&D department leaders and product line directors in the form of "certificates".

At that time, many "innovative products" were blindly innovative from the source, and the product development process was to repeatedly do one thing at a low level, but it could not be done well at once. No matter the function, performance, product quality or product launch cycle, the developed products can not meet the requirements of customers. This has caused a lot of investment waste to the company, and the failed products have also greatly hit the R&D morale. Behind the seemingly prosperous, Huawei is beset with internal crises.

Obviously, the technology-centered approach can no longer be used, and it needs to be transformed into a customer-centered strategic positioning. How to make this increasingly large team achieve efficient cooperation is a difficult problem for Ren Zhengfei.

In 1998, Ren Zhengfei filled his pocket with $50,000 and embarked on a flight to the United States. This was later regarded as a great step for Huawei’s digitalization. In the United States, Ren Zhengfei found his own he is my brother-IBM. At that time, Louis Guo Shina had just completed drastic reforms and saved the huge IBM from the quagmire.

IBM’s path is obviously the template for Ren Zhengfei’s trip.At that time, Ren Zhengfei made up his mind that no matter how much time, money and energy he spent, Huawei should learn this set of things.

In the same year, on August 29th, 50 IBM consultants in suits and ties entered Huawei. Vowed to complete a series of major management reform projects within five years, such as integrated product development reform (IPD), integrated supply chain service reform (ISC), integrated financial service reform (IFS), and lead-to-return marketing reform (LTC).

Taking IPD as the breakthrough point, Huawei applied Product Data Management (PDM), which effectively integrated the company’s professional tools. Manage the final data generated by these tools, so that all product-related information and data can flow effectively throughout the company.

Practice has proved that through the introduction of IPD,On the one hand, the research and development cycle of Huawei products is shortened by half, and the failure rate is reduced by more than 95%; On the other hand, due to the full implementation of this standardized, digital and global asynchronous collaborative product development process and management system.

Third, create an "end-to-end" and globalize the layout of the delivery process

In 2002, shortly after the bursting of the Internet bubble, the global telecommunications market was in a state of decline. The domestic market share of Huawei’s mainstream products has exceeded 40%. For a customer, when choosing a supplier, one monopoly will not be allowed, because one monopoly is very unfavorable for risk prevention in the supply chain and business negotiations, and will be kidnapped by suppliers.

Therefore, Huawei’s growth in the traditional domestic market is weak.

The 2G wireless communication market that Huawei is eager to break through is firmly controlled by powerful international giants such as Ericsson and Nokia, and Huawei has encountered a "ceiling" of growth.

Although Huawei took the lead in developing 3G products among domestic manufacturers, due to various reasons such as shrinking investment, immature industrial chain and unclear 3G standards, domestic 3G licenses have been delayed. After waiting for 3 years, it was the listing of PHS.

This backward PHS wireless technology, with an average annual equipment market scale of about 20 billion yuan, has been built for four years. Together with the supporting mobile phone terminal market (about 20 billion yuan per year), it has expanded Huawei’s largest domestic competitors UT Starcom and ZTE, and they have used their profits to tackle 3G problems and promote overseas markets, and the gap with Huawei has gradually narrowed.

At the same time, important internal executives of Huawei "left" and took away more than 600 R&D backbones. Harbor Network Co., Ltd., which was formed by them, also entered the ranks of Huawei competitors.

In 2002, Huawei’s IPD management reform entered the deep water period, and the pain of reform intensified, but the financial results did not show. This year, Huawei experienced negative growth in history for the first time.

To make matters worse, at this time, Huawei had just occupied the beachhead position of "Asia, Africa and Latin America" in overseas markets, and international rival Cisco began to accuse Huawei of infringing its intellectual property rights in an attempt to stop Huawei’s overseas progress.

In front of Huawei, there is only one way to go, and that is to vigorously expand overseas markets.

Ren Zhengfei once admitted that if Huawei does not make its products cover the whole world as soon as possible, it will be a waste of investment and a loss of opportunities. He believes that we can’t wait until there is no problem before attacking, but we should be familiar with the market, win the market, and train and bring up cadres in the fight of overseas markets. If we can’t build an international team within three to five years, once the China market is saturated, Huawei will do nothing.

Since 2005, Huawei has sounded the charge for developed markets and strategic customers.

In this process, Huawei actively responded to the ISC reform and played a huge role in the face of the surge in overseas business and ensuring the large-scale and low-cost supply and delivery of overseas business. ISC reform extracts the common parts of supply chain processes into shared platforms, conducts centralized management, obtains cost advantages, standardizes digital platforms, and extends integrated supply chain processes to the whole world.

After three years’ efforts, the timely delivery rate of Huawei’s supply chain has increased from 20% at the beginning of management reform to 85%, and the processing efficiency of the supply chain has increased by 35%, ranking among the most efficient enterprises in the information and communication industry worldwide.

Therefore, international customers have full confidence in the quality and innovation of Huawei’s products, which has promoted Huawei to quickly open up a new situation in the international market, and enabled Huawei’s overseas business to quickly achieve a breakthrough in which more than 75% of its sales revenue came from overseas in 2008.

In 2009, Huawei became the second largest supplier in the field of communication in the world with an innovative record of annual sales of $30 billion.

There is a passage in the famous biographer Stefan Zweig’s masterpiece "When the Stars Shine": "A real moment with world historical significance, before a shining moment of human stars appears, there will inevitably be a long time passing away unnecessarily …"

The same is true of enterprise reform. Fortunately, when people talk about Huawei now, its IT architecture changes have made it a shining star.

Fourth, IT2.0 cloud strategy, enter the cloud computing

Walk from behind the scenes to the stage.

In 2010, in order to meet the challenge of global telecom demand becoming saturated and the arrival of big data wave, Huawei actively adjusted its product development strategy and focused on investing in strategic product areas such as 5G R&D and cloud computing. At the end of 2010, Huawei launched the "Yun Fan Plan" and officially announced its entry into cloud computing.

However, after more than 20 years of development, Huawei’s product research and development has moved from following imitation to international advanced, and from international advanced to global leading. It is an essential change of the innovation model for enterprises to move from followers to leaders, which means that Huawei must explore the future direction by itself, instead of catching up with others quickly.

In addition, the business growth of Huawei operators is slow, and the business scale of enterprises is small.

As a result, Huawei has placed strategic growth opportunities in the consumer business represented by smart phones. In order to promote the growth of consumer business, Huawei formally established three BG consumer businesses: operators, enterprises and consumers in 2011, and released the strategy of "cloud management".

At the same time, Huawei set up the 2012 laboratory to conduct basic original research, set up R&D centers in many countries and cities with intensive technical talents around the world, and recruited cutting-edge scientists, mathematicians and aestheticians in various fields around the world.

In the following years, Huawei launched a series of products and solutions based on cloud computing, and its servers, storage and distributed cloud data centers have accumulated a lot of user bases. The data shows that at present, Huawei has built more than 400 data centers around the world, including 120 cloud data centers.

However, at that time, Huawei’s role in the cloud computing market has always been a solution provider and belongs to the "behind-the-scenes hero".

But this situation changed soon.

On April 17, 2018, at the 15th Global Analyst Conference with the theme of "Building a Smart World with the Internet of Everything" held in Shenzhen. Focusing on ICT infrastructure and intelligent terminals, Huawei is determined to be a pioneer in the intelligent world, fully introducing artificial intelligence technology, enhancing the competitiveness of product solutions from all levels of cloud, management and end, and providing customers with a better experience. Xu Zhijun finally mentioned that at this Huawei Connect conference, Huawei will officially release a full-stack, full-scenario artificial intelligence solution.

At this point, Huawei officially stepped forward and entered the dispute with China’s cloud computing.

According to the data recently released by IDC, the public cloud market of China’s big data platform will reach 3.37 billion yuan in 2021, with Alibaba Cloud, Amazon Cloud Technology and Huawei Cloud among the top three.

Huawei’s digital transformation is a typical example of China manufacturing rushing to China to create.

After more than 30 years of hard work, Huawei started with digital management and built a management system dominated by process optimization, constantly optimizing non-value-added processes and value-added processes. Based on this,It has realized the transformation from communication to intelligent terminals, to cloud computing, smart cars and other industrial chains. It is the first batch of enterprises in China to complete digitalization, and it is also a model for most enterprises in China to carry out digital transformation management system.

Why do people eat so many kinds of food every day? Because the body needs balanced nutrients! Every food contains different nutrients, so we need to take them from different foods. In the previous fifteen issues, we focused on the analysis of the effects of seven main nutrients on the body, the proportion of the body, the amount needed and the food source. The content of this issue will help us understand how to easily design a nutritional diet based on the scientific criteria of seven nutrients.

1. Review the main food distribution of 7 nutrients:

1) protein

Beans and bean products (such as soybeans, black beans, tofu, etc.), milk and dairy products (such as milk, goat milk, cheese, etc.), meat (including lean meat and poultry), fish and seafood, eggs, etc. At the same time, some seeds and nuts, such as almonds and walnuts, also contain high protein.

2) Fat

Mainly from oils (such as olive oil, rapeseed oil, fish oil, etc.), meat (especially fat), dairy products, fish (such as salmon, tuna and other fish rich in omega -3), nuts and seeds, and some fruits, such as avocado.

3) Carbohydrate (sugar)

Mainly from rice, flour, potatoes, and some starch-rich vegetables (such as corn and pumpkin). Fruits and vegetables also contain sugar, but their sugar is naturally present, and because these foods are rich in fiber, their sugar absorption will be slow.

4) vitamins

All kinds of vegetables, fruits, nuts, seeds, and animal livers are rich in various vitamins. For example, oranges and strawberries are rich in vitamin C, while beef liver and eggs are rich in vitamin A..

5) Minerals: meat, salt

Meat and fish (such as red meat and shellfish) are rich in iron, dairy products are rich in calcium, bananas and potatoes are rich in potassium, and all kinds of foods contain various minerals.

6) Dietary fiber

Mainly from vegetables, fruits, whole grains (such as oats, whole wheat bread, etc.), beans, nuts and seeds.

7) water

The main source of water is of course water. In addition, fruits and vegetables (such as watermelon and cucumber) also contain a lot of water, and soup and some drinks (such as tea and coffee) can also provide water.

2. General principles of collocation

Nutritional catering, simply put, is to include all the above seven nutrients in the daily diet and mix them reasonably to achieve the effect of balancing nutrition and maintaining health.

Scientifically speaking, it is to design recipes for a day, a week or a month according to the needs of people’s bodies and the contents of various nutrients in food, so that the proportion of protein, fat, carbohydrates, vitamins and minerals ingested by people is reasonable, and the purpose of balanced diet is achieved.

1) the food is diverse and reasonably matched.

Food choices should be as diverse as possible, so as to ensure that the body gets all the necessary nutrients. Include protein, fat, carbohydrates, vitamins, minerals, dietary fiber, etc.

Eat more than 12 kinds of food every day and more than 25 kinds every week on average, and mix them reasonably.

Eat 200-300g of cereal every day, including 50-150g of whole grains and miscellaneous beans and 50-100g of potatoes.

2) Eat more fruits and vegetables, milk, whole grains and soybeans.

There are vegetables in meals. Make sure to eat no less than 300g of fresh vegetables every day, and dark vegetables should account for 1/2.

Eat fruit every day, and ensure that you consume 200-350g of fresh fruit every day. Fruit juice cannot replace fresh fruit.

Eat all kinds of dairy products, and the intake is equivalent to more than 300ml of liquid milk every day.

Always eat whole grains and soy products, and eat nuts in moderation.

Nuts are beneficial and should not be overdosed, with a weekly intake of 50-70g.

3) Eat fish, poultry, eggs and meat in moderation.

Fish, poultry, eggs and meat should be taken in moderation, with an average of 120-200g per day.

It is best to eat twice a week or 300-500g, 300-500g of eggs and 300-500g of livestock and poultry meat.

Eggs are rich in nutrition, and you don’t abandon the yolk when eating eggs.

Eat less deep-processed meat products.

Give priority to fish and eat less fat, smoked and pickled meat products.

Cooking methods, more cooking, less frying.

Eat both soup and meat. Eating only soup without meat can’t make full use of nutrients in food, resulting in a great waste of food resources. In fact, the nutrition of the fleshy part is much higher than that of the soup.

4) Less salt and less oil, sugar control and wine restriction.

Cultivate light eating habits and eat less high-salt and fried foods. Adults should consume no more than 5g of salt and 25-30g of cooking oil every day.

Control the intake of added sugar, not exceeding 50g per day, and preferably below 25g.

Trans fatty acids do not exceed 2g per day.

Children, teenagers, pregnant women, nursing mothers and patients with chronic diseases should not drink alcohol. Adults who drink alcohol should not drink more than 15g a day.

5) Eat regularly, drink enough water and arrange three meals a day reasonably.

Eat regularly, don’t overeat, don’t be partial to food.

Drink plenty of water, a few times, 1700ml for men and 1500ml for women every day.

Do not drink or drink less sugary drinks, and do not use drinks instead of white water.

3. Tips for food collocation

Each kind of food contains rich varieties, which can be interchanged with each other, avoiding the monotony of food and helping to enrich three meals a day. For example, the staple food can be exchanged between rice, noodles, millet porridge, whole wheat steamed bread and miscellaneous grains rice; Sweet potato and potato exchange; Pork is interchangeable with chicken, duck, beef and mutton; Fish can be exchanged with shrimp, crab, shellfish and other aquatic products; Milk can be interchanged with yogurt, cheese and goat milk.

1) Meat and vegetable collocation: that is, there is meat and vegetables in food.

2) Main and auxiliary collocation: staple food (rice, noodles, etc.) and non-staple food (chicken, duck, fish, fruits, vegetables, etc.) must be available.

3) Miscellaneous collocation: Staple food should pay attention to increasing whole grains and miscellaneous beans. When cooking staple food, rice can be paired with brown rice, miscellaneous grains (oats, millet, buckwheat, corn, etc.) and miscellaneous beans (adzuki beans, mung beans, kidney beans and flower beans). Second, rice, mung bean rice, red bean rice and eight-treasure porridge are all good ways to match the thickness and increase the variety of food.

4) Dry-thin collocation: that is, there are dry foods (such as cooking or rice) and water-rich foods (such as soup or porridge).

5) color matching: that is, the color and depth of food, that is, people’s sensory enjoyment. For example, when frying green beans, put a little carrot and corn in it, the color will look better, which can increase the appetite of children. At the same time, it means eating all kinds of food. Dark vegetables refer to non-white light vegetables such as green, red, yellow, orange and purple.

4. How to achieve a balanced diet?

Balanced diet refers to the balance between calorie intake and heat consumption, the reasonable percentage of three thermogenic nutrients, and the balance between animal protein and plant protein.

A balanced diet should first meet the human body’s needs for calories. The percentage of the three thermogenic nutrients in the total calories should be: protein 10% ~ 15%, fat 20% ~ 30%, and carbohydrate 60% ~ 65%.

The amount of protein food in a meal should account for about a quarter of the plate.

The content of high-quality protein is more than 1/3.

Omega-3 fatty acids and Omega-6 fatty acids are 1:1.

The intake of saturated fat should be as little as possible (it is recommended to account for less than 10% of the total calories).

The ratio of three meals a day can be 3:4:3, that is, breakfast accounts for 30%, lunch accounts for 40%, and dinner accounts for about 30%. Adults have three meals a day, children and the elderly have three meals plus a snack, which can be between breakfast and lunch, or between lunch and dinner.

Don’t take it seriously! Professionals tell you what to pay attention to when participating in wading activities.

  CCTV News:On the afternoon of the 7th, local time, a joint press conference was held by the government of Phuket, the Royal Thai Navy, the regional police station and the public health department of Phuket to inform the latest progress in the rescue of the capsized cruise ship in Phuket. The Thai side said that a total of 8 bodies of the victims were found that day. Up to now, the number of victims has risen to 41, and another 15 people are temporarily unable to verify their whereabouts. At present, 16 tourists from China have been confirmed dead.

 

  At present, the accident is still being rescued, and the cause of the accident still needs to be investigated. However, it needs to be reminded that in recent years, island tour has become the choice of many tourists, but the ensuing wading safety accidents have risen rapidly, so how can tourists protect their own safety while enjoying the pleasant sea breeze?

  Pay close attention to the weather and don’t take warning information seriously.

  In the rainy season on the island, the changeable weather becomes a major cause of accidents. When participating in wading activities, we must pay close attention to the weather and not be lucky about the early warning information.

 

  Hu Xiao, Meteorological Analyst, Public Meteorological Service Center of China Meteorological Administration: "If you come to tropical waters like Phuket in rainy season and go out to sea, and the weather forecast predicts thunderstorms, it can be said that there are certain risks. There is an obvious change in the weather. The weather is gloomy, the wind suddenly increases, or the tide suddenly changes, all of which tell us that we need to dock for safety, and we must not be lucky. In a word, it is very important to know the climate and weather in advance in this tropical country, and travel safety is the first. "

  Pay attention to the risk of launching, and wear a life jacket.

  

      

  When you are at the beach or swimming pool, be sure to walk together. Don’t go into the water alone without the supervision of a safety officer. When physical conditions do not allow, you should avoid wading activities. In case of stormy waves or red warning flags on the beach, you must not go into the water. Some sea areas seem calm, but in fact, the underwater undercurrent is swift and dangerous. In July, 2017, three male tourists from China went swimming in a private beach in Phuket despite the warning of wind and waves, resulting in two of them drowning.

 

  Wang Yingxi, captain of the cave expert rescue team of Beijing Pinglan Public Welfare Foundation: "Always wear a life jacket when wading in the water to prevent accidents."

  Diving needs to be carefully guided by professionals.

 

  Snorkeling and deep diving are dangerous projects, and tourists who are old or suffering from heart disease, high blood pressure and other diseases cannot participate. If you take part in snorkeling projects, visitors must attend the training on the use of snorkeling masks in advance, and then go into the water after they can use them skillfully. Most importantly, you must follow the guidance of professionals when you participate in diving projects.

  Wang Yingxi, captain of the cave expert rescue team of Beijing Pinglan Public Welfare Foundation"Don’t do actions that are forbidden by tour guides or diving instructors. China tourists are not familiar with the waters here, nor the sea and related dangers here."

Behind the high-speed tragedy of Xiaomi Automobile: In February, it just completed the full-scale push of "end-to-end" intelligent driving.

K diagram 01810_0

  Xiaomi SU7 car accident is still continuing to ferment. In addition to focusing on whether the door can’t be opened and the front of the car catches fire, a lot of attention is focused on whether the active safety functions such as emergency braking (AEB) of Xiaomi SU7 are triggered in the accident.

  On the evening of April 1,The official once again issued a statement that Xiaomi SU7 Standard Edition has two sub-functions of forward anti-collision assistance, including collision warning (FCW) and emergency braking (AEB), which are targeted at vehicles, pedestrians and two-wheelers, and the working speed of AEB function is between 8-135 km/h. This function is similar to that of AEB with the same configuration in the industry. At present, it does not respond to obstacles such as cones, water horses, stones and animals.

  In short, Xiaomi believes that the current AEB function does not support the identification of roadblocks in accidents, but it does not support the same configuration models in the industry.

  In this regard, an intelligent driving industry person told reporters that construction roads will generally be marked on high-definition maps, and guiding NOA to divert will remind them to take over. If the intelligent driving system gives a certain weight to the real-time updated HD map, there is a certain probability to avoid the accident.

  According to official information, the company just completed the full-scale promotion of "Xiaomi End-to-end Full Scene Intelligent Driving (HAD)" in February this year, indicating that "end-to-end user driving data training has been introduced, and on the basis of" no map ",the trajectory is more anthropomorphic, traffic is more efficient and driving is safer", and it is clear that HAD covers highways, urban expressways and so on.

  The price of "no graph"

  When discussing the boundary between intelligent driving ability and responsibility, we have to admit that even in the case of artificial driving, Xiaomi SU7 has a certain probability of distress in this German-Shanghai expressway accident.

  According to Xiaomi’s notification, before the accident, the vehicle was in the state of NOA intelligent assisted driving and continued to drive at a speed of 116 km/h. Due to construction repairs, the road section was closed with roadblocks and diverted to the reverse lane.

  At present, the official police report has not been made public. However, because the speed is too fast, and Deshang Expressway is located near Jiuhuashan Mountain, and the lighting situation at night is not good, whether the direct cause of the accident is caused by the vehicle hitting the roadblock at the high-speed NOA or the driver’s improper steering+braking after taking over is actually inconclusive (although Xiaomi may be to blame in both cases).

  So, why can’t high-speed NOA recognize lane changes?

  A person in the smart driving industry who did not want to be named told the reporter that this may be related to the fact that the smart driving system does not use high-precision maps, or the decision-making weight of maps in the smart driving system is too low.

  "If the intelligent driving system uses a high-precision map, at least it will prompt the construction ahead, and then NOA’s route planning will be different," the person said, but pointed out that when dealing with the diversion, whether to continue NOA according to the new road or slow down and ask for takeover, each scheme may be different.

  However, the interviewee also told reporters that road construction is divided into temporary construction and planned construction, and the planned construction will generally be uniformly marked on the road network, prompting the smart driver to change the route. But the temporary construction information is "not necessarily" uploaded.

  Considering the risk of landslide caused by the geographical location of the German-Shanghai Expressway, the possibility of temporary construction is also great-however, the interviewee revealed to the reporter that according to his understanding, this construction is not temporary construction.

  The reporter looked up the official subscription number of Xiaomi Automobile and found that at the early stage of Xiaomi SU7′ s release, the company publicized that it adopted the "light map" urban NOA scheme. However, in October last year, Xiaomi announced that it had pushed version 1.40 smart driving in large quantities, and made it clear that the NOA function of the city allowed vehicles to avoid construction.

  However, on March 19 this year, the subscription number issued a document, saying that in February this year, the end-to-end full-scene intelligent driving function was fully pushed, and it was repeatedly emphasized that the intelligent driving system was "no map".

  "Xiaomi’s plan is biased, and there is definitely no high-precision map at the bottom. Another system design is problematic." The aforementioned person pointed out to the reporter: "In fact, Cheluyun is a way to achieve automatic driving with the lowest collaborative cost."

  Of course, car dealers flaunt "no map" not simply to reduce costs. According to the reporter’s understanding, the pure vision scheme will contradict the HD map that is not updated in time to a certain extent. In the choice of reference weight of intelligent driving system, in order to avoid the contradiction of reference data and make decision-making difficult, we will also give up high-precision maps on our own initiative.

  The boundary of "pure vision"

  Then, since we chose "no map" and emphasized perception, what about Xiaomi’s perception ability?

  Back to the Xiaomi accident vehicle, from the sensor configuration point of view, the intelligent driving sensor configuration of the SU7 standard version Pilot Pro is two forward-looking, three upward-looking, four around-looking, a rear-looking camera and a forward millimeter-wave radar (of course, there are 12 ultrasonic radars, but the ultrasonic radar has insufficient performance and almost no weight in high-speed intelligent driving decision), commonly known as "9+1" configuration.

  And this configuration is almost the same asThe plan is exactly the same. The HW 4.0 system is equipped with four side-looking cameras, three front-looking cameras at the top and a rear-looking camera at the tail, including a forward millimeter-wave radar at the front of the car, which is "7+1" configuration.

  The intelligent driving decision-making system, which relies almost entirely on the camera, undoubtedly belongs to the so-called "pure vision scheme".

  So, how reliable is the pure vision scheme? Can you handle unexpected emergencies?

  Last year, the media conducted an in-depth report.Many casualties caused by opening FSD were exposed and analyzed.

  In the report, FSD caused many "stupid" accidents, such as directly rushing out of the T-junction and chasing a police car with flashing warning lights. And one of the accidents is a typical warning to the pure vision scheme.

  In this accident, the driver who started the automatic driving almost ran straight into the truck chassis that rolled over and heeled in three lanes at a medium speed of about 40-50 km/h around 3 am, causing the driver’s death. It is worth noting that, from the video, the rollover truck is huge in scale, close to three meters in height, while the lighting conditions on the road are acceptable, the speed is not fast, and the human eye can quickly capture and respond in time.

  However, in the face of this simple emergency treatment from the perspective of natural persons, Tesla FSD, which was advertised as surpassing human driving ability, caused an accident.

  The media quoted automobile engineering experts in colleges and universities as saying that the above-mentioned incidents may have occurred because Tesla could not identify the chassis characteristics of rollover trucks and mistook them for roads or backgrounds, so no emergency treatment was carried out.

  This also brings a soul torture to the pure visual route: pure visual intelligent driving not only needs to know cars, but also needs to know things, not only pedestrians, pets, or even suddenly dumped goods-more unexpected irregular objects may become the culprit of traffic accidents.

  Judging from Xiaomi’s reply, AEB system really can’t give feedback on the diversion obstacles such as cones, water horses, stones and animals. However, Xiaomi officially insists that AEB, a "friend", can’t do it either.

  But the problem is that the standard version of Xiaomi SU7The number of equipment is almost "stingy" compared with that of friends at the same price, and the decision-making also depends entirely on pure visual ability, so it is obviously not convincing to compete with AEB system alone.

  According to the data of knowing the car emperor, in the same price model, such as the ideal L6 intelligent driving sensing configuration is almost the same as that of Xiaomi SU7-but more include007, Tucki P7,Each configuration version of Han EV and Seal is equipped with at least 5 millimeter-wave radars and 1.; At least three or more millimeter-wave radars are equipped on the models of Wujie M5/M7 and Tucki P7+.

  In other words, compared with "friends", the security redundancy of Xiaomi SU7 Standard Edition is far from enough.

  "The training of a qualified driver, in addition to road traffic rules and driving skills training, relies more on the accumulation of intangible life experience to gain the ability to cope with emergencies. This is precisely the gift of life to mankind, and it is alsoAt present, it is far from the realm. We may be able to achieve pure vision in the future, but we should not train intelligence through accident accumulation. "The person from the aforementioned listed company told reporters:" Lei Jun (Xiaomi) may not be washed this time. "
