Tips for preventing drowning

SUMMER

2019

Drowning is the "number one killer" of children’s accidents. Summer has arrived, the weather is hot, children’s outdoor swimming and other activities have become frequent, and drowning accidents have entered a high incidence period. Parents must always remind, educate and pay attention, enhance safety awareness and guardianship awareness, earnestly assume guardianship responsibilities, strengthen education and management of children, and prevent accidents caused by drowning. I hope the following drowning prevention tips can help you.

NO.1 main points of drowning prevention

1. It mostly happens on weekends, holidays or after school;

2. Most of them occur in unattended rivers, ponds and other wild waters;

3. Most of them occur in rural areas;

4. Most of them occur in the process of students playing together;

5. Most of them occur in primary school students and junior high school students, and most of them are boys.

NO.2 "six noes" for preventing drowning

1. Do not swim in the water without permission;

2. Do not swim with others without authorization;

3. Do not swim without parents or teachers;

4. Do not swim in the waters without safety facilities and ambulance personnel;

5. Do not swim in unfamiliar waters;

6. Students who are not familiar with water are not allowed to go into the water for rescue.

NO.3 drowning prevention measures

1. Swimming should be led by adults;

2. Don’t play alone by the river or the mountain pond;

3. Do not go swimming in non-swimming areas;

4. Those who can’t swim, don’t swim to the deep water area, even if they are carrying lifebuoys, it is not safe;

5. Make proper preparation activities before swimming to prevent cramps.

NO.4 drowning self-help method

1. Don’t panic, call for help immediately when you find someone around you;

2. Relax your whole body, let your body float on the water, float your head out of the water, kick the water with your feet to prevent physical loss and wait for rescue;

3. Get rid of the heavy objects in shoes and pockets in time. When your body sinks, you can press your palm down.

4. If you suddenly cramp in the water and can’t land, call for help immediately. If there is no one around, you can take a deep breath and dive into the water, straighten the cramped leg and pull your toes up with your hands to relieve the cramp.

NO.5 rescue method for drowning in others

1. When you find the drowning person, you should call for help at the first time, seek the help of the surrounding adults, and call 110 to call the police. Don’t blindly go into the water to rescue;

2. You can hand the bamboo pole to the drowning person, provided that you ensure your own safety. When handing the bamboo pole, you should lie on the ground and lower your center of gravity to avoid being dragged into the water.

3. If floating objects such as foam blocks, lifebuoys and wooden blocks can be found at the scene, they can be thrown to the drowning person to prevent the drowning person from sinking into the water;

4. If there are no bamboo poles, floating objects, etc. at the scene, you can take off your clothes and connect them as a rope and throw them to the drowning person. Remember to lie on the ground to ensure your own safety.

Here, we also propose to the general public:

The weather is getting hotter and hotter. I hope all citizens and friends will pay attention to it at any time. If you find minors (especially small boys in groups of three or five) swimming, splashing and playing in ponds, rivers, reservoirs and other places without guardians, please stop them in time! Action by the whole people, starting from you and me and starting from the side!

Let’s act together,

Cherish life and prevent drowning, starting from me!

Bai Yansong said:

"Whether a person has a culture is not based on how high his education is.

People with academic qualifications do not necessarily have culture; People without education are not necessarily uneducated.

Reading a lot of books, having a high diploma, and having education are sometimes completely different. "

People who are truly literate have achieved the following.

01

A flight attendant named Judy told an interesting story about Liu Shishi on the Weibo.

As a stewardess, Judy often meets all kinds of big coffees and stars, but these big coffees and stars didn’t leave a deep impression on her until she met Liu Shishi a few days ago.

On that day, Liu Shishi took the first class. When Judy went to tidy up the first class after the plane landed, she was surprised to find that the quilt on Liu Shishi’s seat was neatly folded.

Judy was shocked at once:"In the past, all the guests in the first class huddled their quilts, threw them under their feet and left. I didn’t expect the poems to be stacked neatly. I was so touched."

People who fly in first class are usually people of great status, but you see, there are so few people who fold quilts. Occasionally, a flight attendant will be moved for a long time.

02

On May 1 ST, I met a wandering singer on the road. The singer sang very well. After a song, many people walked by and threw the change into the singer’s hat, but then, a lady’s behavior surprised people.

She went to the hat and crouched down slowly.Gently put two coins into the hat, and smiled and nodded to the wandering singer.

Educated, I don’t care if I have read many books. But at this moment: many people lose her too much.

Comparing this matter, I am reminded of Bai Yansong’s words:

"Whether a person has a culture is not based on how high his education is. People with academic qualifications do not necessarily have culture, while those without academic qualifications do not necessarily have no culture. "

Read a lot of books, have a high diploma,And whether you have culture or not are sometimes completely different.

Wu Xiao Xian told another touching story.

Once, he followed the boss to talk about business, and at lunch, he ordered a table in the hotel.

Halfway through the meal, the waiter served a special dish, and the boss said politely, "Thank you, we don’t need any more dishes."

The waiter explained:"This dish is free."

The boss still smiled and replied: "We don’t want it for free, we can’t eat it, it’s a waste."

After the meal, the boss wrapped the leftovers.

On the way back to the company, the boss drove slowly, as if looking at something.

Wu Xiao Xian was wondering when the boss stopped the car, picked up the packaged food, got off the bus and walked over to a beggar, and handed it over with his hands.

What is culture? This is culture. Culture is self-cultivation rooted in the heart.

04

I read another story in People’s Daily.

On the weekend, my nephew followed a Chinese to go fishing in Sydney, Australia. Every time you cast a net, you always get something.

But every time the net is pulled up, the Chinese always pick it up and throw most of its shrimps and crabs back into the sea.

His nephew was puzzled: "I finally hit it, why throw it back?"

Chinese answer:"Fish and shrimp that meet the specified size can be caught."

His nephew said, "No one can care about you on the high seas?"

The Chinese smiled faintly: "Not everything needs to be reminded and urged by others!"

What is culture? This is culture. Culture is consciousness without reminding.

05

What is freedom?

Many people’s understanding is that freedom is to let yourself do what you want freely.

But people who think like this don’t know what real freedom is.

Linda, a Chinese-American writer, wrote a book "Worry in the Deep of History", which presents a fact:The United States is both the freest country in the world and the least free country in the world.

On one occasion, he accompanied his friends to visit the Grand Canyon of America.

My friend picked up the coke can and wanted to throw it into the Grand Canyon: "What a pity not to do something in such a deep canyon!" "

Linda got a fright, hurriedly stop:"This is illegal."

The freest America in the world is actually full of illiberality:

It is illegal to hold an open wine bottle in the street;

It is illegal for parents to slap their children when they cry.

……

Many people in China don’t understand why the United States has so many restrictions. In fact, it is precisely because of so many constraints that American freedom has been created.

The philosopher Mill said: "Constraints are the mother of freedom. Personal freedom must be based on not infringing on the freedom of others. "

What is culture? This is culture. Culture is freedom based on constraints.

06

There was a man who taught his disciples to break glass products and put them into garbage bags, and wrote on them with a pen: "There are glass fragments inside, it’s dangerous!" "

In this way, garbage collectors won’t scratch their fingers.

The mineral water bottles after drinking drinks are also emptied and tightened, which is convenient for waste recyclers to collect.

You ask me what is culture? This is culture. Culture is kindness for others.

When going to the toilet, think of the next person who goes to the toilet;

When throwing garbage, think of the next garbage collector;

No matter what you do, you must think of the next person;

……

Xia Yan, a dramatist, was in great pain before he died.

The secretary said, "I’ll call the doctor."

Just as he was about to open the door, Xia Yan opened his eyes and said with difficulty:"Not called, please."

Then he passed out and never woke up.

"Not called, please." Xia Lao changed a word, but touched a building.

Xia Lao is a truly literate person.

A true literate person does not depend on how many books he has read or what school he has attended, but should have four qualities:

Cultivation rooted in the heart;

Consciousness without reminding;

Freedom based on constraints;

Kindness for others.

Many times, culture is a hidden existence, and it is a criterion of life. It may not be visible, but it’s important.

It will make you richer in thought, more advanced in choice, more independent in doing things and more interesting in life, all of which are good for you.

Cover journalist Tan Yuqing Bian Xue

In recent years, scoliosis has become a common disease that harms teenagers, making it difficult for sick teenagers to straighten their backs. According to statistics, the number of scoliosis among primary and secondary school students in China exceeds 5 million, and it is still increasing at a rate of about 300,000 per year. Scoliosis has become the third major disease that harms the health of children and adolescents after obesity and myopia.

Early detection, early diagnosis and early treatment are the key points to combat scoliosis, otherwise it may develop into a very serious deformity, which may affect cardiopulmonary function and even lead to paralysis in severe cases.

Scoliosis model

In the past, doctors would diagnose scoliosis by manual measurement and X-ray screening, but with the integration of artificial intelligence (AI) into medical imaging technology, this step may be further optimized. In the screening stage, it is only necessary to "simply take pictures" to preliminarily determine whether scoliosis occurs, and in the diagnosis stage, the "experienced" AI system can also assist doctors to quickly read films for diagnosis.

Why can taking pictures replace x-rays? How does AI system assist doctors in screening and diagnosing scoliosis? Recently, the cover journalist explored the development of AI+ medical imaging technology.

It only takes a few seconds. Did the AI system tell you about scoliosis?

In the "simulated physical examination room", the reporter saw the hardware part of the spine AIS intelligent screening and diagnosis system (hereinafter referred to as the "system")-a rectangular metal frame about 2 meters high, with a group of small cameras in the center of the top. It looks simple, but the effect is not simple. The reporter’s on-site experience found that it took only a few seconds from detection to obtaining the report results.

The hardware part of the system is the camera.

"As long as the examinee stands in a standard position and poses Adam’s position to expose his back, the system can quickly complete the screening by using an infrared depth camera to collect information on his back." According to Fan Jipeng, the person in charge of the Shuangxin Department of Chengdian Gold Disk, the system will map and transform the image information collected by the camera to get the depth information of multiple posture key points on the back, so as to calculate the back asymmetry index and judge whether the subject may have scoliosis.

Schematic diagram of screening process

He said that this intelligent system will get closer and closer to the level of X-ray diagnosis by constantly learning actual cases and optimizing existing algorithms. While ensuring the accuracy and efficiency of screening, it can also prevent the teenagers being tested from being exposed to X-ray radiation.

This new technology may help to better implement the scoliosis examination project that was included in the physical examination of students in 2022. "We think the greatest significance of the screening system is that it can quickly complete large-scale examinations, so that children with scoliosis who have not yet been discovered will not be delayed."

Interface of scoliosis diagnosis system

In the diagnosis stage, the intelligent system is also a good assistant for doctors. Fan Jipeng explained that in the traditional process, in order to diagnose scoliosis, doctors need to measure the Cobb angle of the spine with a ruler, but this is time-consuming. Different doctors will make some errors when measuring by hand. Doctors with less experience may need to consult for scoliosis with large curvature, and the diagnosis time will be prolonged. However, after deep learning, the artificial intelligence system can accurately read and measure the film within 3~5 seconds, and give diagnosis suggestions.

At present, the system has completed the screening and diagnosis of more than 5,000 cases of scoliosis. "Now we are cooperating with Electronic Science and Technology University Hospital, Zhongshan Pok Oi Hospital and Shenzhen Children’s Scoliosis Center, and this number will be continuously updated."

Training "AI Good Doctor" by "Engraving" Algorithm of Expert Experience

"The accuracy of top doctors’ diagnosis of scoliosis may be 85%~90%, and the overall accuracy of our system will continue to approach this figure." Fan Jipeng said that at present, of course, the accuracy of top experts is higher, but compared with ordinary doctors, the system may have exceeded their basic level.

So, what gives the diagnosis system the ability to catch up with top experts? The answer is the experts themselves.

"When experts mark the angles of thousands of scoliosis cases, the system will learn based on this and solidify the experience of top experts into the algorithm, thus reaching a higher diagnostic level." In Fan Jipeng’s view, although the system is not as good as top experts, it is used to assist ordinary doctors in diagnosis or help improve their medical level.

The marked samples provided by human experts are the "success stories" of artificial intelligence doctors, but Fan Jipeng said that this is also one of the difficulties in the development of AI doctors. Different races, even people in different regions, will have certain differences. If the diagnosis is accurate enough, researchers need to collect as many samples as possible for AI to learn.

At present, the real large-scale landing of the system still faces some difficulties in the process. "How to make the medical examiners go through the inspection process quickly and how to ensure that their Adam posture is standard requires some corresponding training."

Therefore, the system will learn more practical cases, further optimize its algorithm program, continuously improve the diagnostic accuracy, and design detailed operating standards for the system, "for example, what is the standard Adam position, how to do it well, etc."

A paradox lies before Mourinho.

Is Rome useless or useless? In March, halfway through the Devil’s schedule, Mourinho is worried about a long list of injuries. At present, there are important players absent from the third-line positions except the goalkeeper. The media are talking about the need for Rome to make a rotation, but this is Mourinho’s embarrassment.

Rotation. Who? Take the midfield as an example. I’m afraid Marty Camara himself can’t remember the last time he played. Mourinho would rather let Cristante and Ma Diqi fight repeatedly than send him to play. Even the teenager Tasirovich has temporarily replaced him, while Camara has almost disappeared. Some media rumors that he is injured, but since 2023, he has been healthy enough to enter the big list and sit on the bench. Some critics say that Rome will use him only if it is necessary, mainly because he is worried that his appearances will be full.

Not only Camara, but also young players such as volpato and Tacirovich, who had been highly anticipated by Mourinho, have lost their chances in the standing list after a period of tempering. Young Beauvais was once in Mourinho’s plan, but he still couldn’t play the main role after the game was tempered. Rome had hoped to use him and volpato as additions to the purchase of Fratesi during the winter transfer.

Also gradually disappearing in the starting lineup is celik, the winner of the bid. celik has not played in four games since he came out after Rome defeated Verona’s substitute Solbakken 1-0 on February 20th. Some media have analyzed that the confidence of Turks has been affected since the goal against cremona, and the strong comeback of Karsdorp and the rapid growth of Zalewski have compressed the space of celik.

Of course, for coach Jose Mourinho, he is more aware of different tactics and player arrangements for different opponents, just like when he played against Real Society, he used Karsdorp accurately, which inspired the fighting spirit and energy of the Dutch. Similarly, Camara, Tasirovich and celik do not mean that they have been completely abandoned. They can only play when Mourinho thinks fit. In the past, many media questioned that Mourinho often went his own way and didn’t know how to rotate. In fact, Rome suffered from rotation at many times this season. In the two games against cremona, it happened that Mourinho tried to rotate, and the result was without exception.

This is also Mourinho’s embarrassment, rotation? Losing, not rotating? Lack of physical strength may lose the game. In desperation, he had to give up his own ban, so as to encourage and infect the only main lineup, and let them believe that they have the ability to conquer everything and believe in the strength of team and blood. However, his inner helplessness has long been revealed. At the press conference after the Europa League match, he envied Bayern’s substitute lineup and said that even if those people only gave him one player, it would be good. This is also his difficulty to some extent. In Rome, it is not that no one is available. The real problem is that some people are really useless.
