With the rapid development of digital technology, artificial intelligence is becoming a core competitive advantage in the field of education. Its iterative upgrading has not only brought revolutionary changes to teaching practice, but also brought unprecedented creativity to the education industry. Ms. Fan Bo, general manager of Aiqiyi Quanzhixin Education, pointed out: With the development of artificial intelligence, it marks that the field of education is moving towards a brand-new era.

　　First of all, in terms of teaching mode, the application of artificial intelligence is changing the traditional dual structure of "teacher-student" and introducing the ternary teaching mode of "teacher-student-machine". The support of intelligent teaching tools and platforms has become the key. These tools can not only provide personalized learning paths, but also provide accurate teaching feedback for teachers through data analysis, so as to realize personalized teaching, make up for the weak links of strengthening students and maximize the teaching effect.

　　Secondly, under the teaching mode of man-machine cooperation, the role of teachers is changing. They are no longer simple knowledge transmitters, but become the motivators of students’ learning internal drive, guiding students to explore the ocean of knowledge. At the same time, teachers have changed from the leader of the teaching process to the leader of the education process, helping students to build a knowledge system and cultivate their autonomous learning ability.

　　At the same time, students’ autonomous learning ability is particularly important in this process. With the great enrichment of educational resources and the expansion of educational space, students can study in a more diverse and open environment, which is no longer limited by traditional classrooms. The application of cognitive model has changed the way of knowledge production and knowledge dissemination, and brought far-reaching influence to the field of education.

　　Ubiquitous education has once again taken the lead in educational innovation by using artificial intelligence (AIGC) technology, and launched a series of cutting-edge courses, aiming at training students to master and apply the latest AI-generated content (AIGC) technology. The courses of "AIGC Design" and "AIGC Writing" under the company are well received. At the same time, based on the existing audio and video transmission technology and intelligent network, Universal Education innovatively launched a variety of online education products and services, including live broadcast, interactive live broadcast, recording and broadcasting, interactive recording and broadcasting, AR, VR, MR and so on. Reach more users quickly and accurately through the big data intelligent recommendation system.

　　Our "AIGC Design" course will teach students how to use AI tools for creative design, including graphic design, UI/UX design, animation production and other fields. The course covers the operation skills of AI design tools, the innovative application of design concepts, the acquisition of design core typesetting and color matching skills, the disassembly of aesthetic principles and practical cases, etc., in order to cultivate students’ innovative thinking and practical ability.

　　The course "AIGC Writing" emphasizes practicality and innovation, especially its application in content creation, copywriting and news editing. The course will introduce the use of AI writing tools, teach students how to efficiently generate texts with AI assistance, and at the same time emphasize maintaining the unique perspective and creativity of human authors to ensure the originality and attractiveness of the content. In addition, the course also focuses on the creation and incubation of personal brands, guiding students how to give play to their personal interests and hobbies through creative content output, establish and enhance their personal IP influence, and achieve creative efficiency and dimension improvement, thus realizing more possibilities for self-media sideline and new careers. The project also won the award of "China Science and Technology Innovation Enterprise of the Year in 2023 -AIGC" in the new economic peak list of Ai Media, which is also a high recognition of the achievements of Universal Education in the field of AIGC.

　　Universal education has always been committed to promoting the development of education through technological innovation, which not only responds to the demand for updating educational content in the digital age, but also provides students with the necessary skills to adapt to the future workplace and increase their competitiveness in their careers.

　　In the future, Ubiquitous Education will continue to explore the deep integration and application of artificial intelligence technology and educational practice, provide students with more high-quality learning resources, and constantly promote the innovation and upgrading of education and teaching with the "golden key" of artificial intelligence.

Hello, I’m Lu Snake, and today I’m going to talk about football in China!

Speaking of China football, the most important thing recently is that the Football Association has a new head-Song Kai. As a football fan in China, I think this is at least a positive signal, because it shows that the football community in China is trying to improve its own problems and promote the development of football in some way.

Historically, the development of football in China has been plagued by various problems, including mismanagement and corruption. Therefore, changing the president of the Football Association can bring new ideas and directions for the development of football, help solve these problems and promote the healthy development of football in China.

After the new president takes office, he may take a series of measures to improve the football situation in China, including strengthening management, promoting professional development, strengthening the construction of youth training system and improving the quality of coaches and players. From the recent developments of the new head of the Football Association, we can also get a glimpse of it. Then, next, I will sort out the recent events that seem to me to be more important.

1. Debut: "Take youth training as a top priority"

On November 22nd, the second leg of the U15 final in China Youth Championship was held in Weifang, Shandong Province. Football Association President Song Kai, Vice President Xu Jiren and Secretary-General Yuan Yongqing appeared together.

The newest Football Association’s leadership team, which made its first collective appearance, chose youth football matches, fully expressing its attention to youth football. In the words of Song Kai, "China Football Association should take youth training as a top priority." How can we improve the quality of youth training? Song Kai mentioned, first of all, "let the best coaches do youth training", "I have been doing the three big balls in Liaoning for a long time, so I can do some guidance from the policy and system, such as improving the treatment of echelon coaches. In the process of children’s growth, a more competitive competition system is established. "

2. Meeting with AFC President, breaking ice in football foreign affairs.

Song Kai, President of China Football Association, who just arrived in Doha, Qatar, met with Salman, President of AFC, who was also attending the 2022 AFC Awards Ceremony. This is the first time that Song Kai has face-to-face communication with the president of the Asian Football Association as the president of the China Football Association, and it also marks the beginning of the new China Football Association to break the ice for football foreign affairs and take an important first step.

It is understood that during the meeting, Salman reiterated to Song Kai that the AFC will continue to cooperate with the China Football Association to support them in revitalizing football in China.

Subsequently, in its important position in official website, the AFC focused on the meeting between Song Kai and Salman with the title "AFC President praises the football development in China". The AFC quoted Salman as saying: "The AFC will unswervingly strive to make football the number one sport in the Asian continent. I believe that China Football Association can help China football to a higher level under the leadership of President Song Kai. We will also work together for this. " Salman also said: "What is exciting is that we see the determination of the new leadership of China Football Association to develop football and promote the progress of football in China. Football still has great development potential in China. "

3. Study and open the foreign aid policy of the Super League to increase the appreciation of the league.

After Song Kai took office, in view of the situation of the Super League, he said that he would strive to create a professional league that people are satisfied with, and study the foreign aid policy of opening the league against the AFC. At present, the foreign aid policy of the Super League is 654, and his new policy is expected to be "51", that is, five non-nationals and one Asian foreign aid can play at the same time. The implementation of this policy will increase the internationalization and fierce competition of the league, attract more excellent players to China, improve the competitiveness of the league, and at the same time, improve the enjoyment and entertainment, so that fans can enjoy more exciting games.

Finally, I hope the new president can take effective measures to promote the healthy development of football in China, so that we fans can pay more attention to the future of football in China with pride.

If you have any expectations for China football or what do you think of the new head of the Football Association, you are also welcome to leave a message in the comment area for discussion.

　　In the diving field, China team has the reputation of "Dream Team". A diving action completed in a few seconds, the average audience usually sees the effect of entering the water, that is, the size of the splash. In fact, splashing is also a high-precision technology. A reporter from Beijing Morning Post recently invited Yu Fen, head coach of Tsinghua diving team, to give a detailed answer to this technology.

　　Hand shape

　　There are slight differences between China and foreign countries.

　　In the diving competition, watching the slow-motion replay will find that the athletes enter the water with their palms in contact with the water surface, not the fingertips as generally believed. A "technical post" circulating on the Internet explains that water spray belongs to the category of fluid mechanics, that is, the process of collision between solid and fluid. Entering the water with your fingertips is equivalent to forming a wedge, so when you fall into the pool, you will find a way out along the direction of least resistance because of the incompressibility of water, and the inclined plane of the wedge is this direction. However, when the object colliding with water has a certain cross section, the water mainly moves laterally, and it can’t be rushed up due to the pressure of the surrounding water, which is the reason why the palm spray is small.

　　Yu Fen introduced that in the past 40 years, the technology of pressing the splash with the palm of your hand has been widely used in countries with relatively advanced diving. "We call it the palm-turning technology. The main point of action is to point your palm at the point where you want to enter the water at the moment of entering the water, and hold the other hand with one hand. " This is the hand type commonly used by athletes in China, while some foreign athletes will put their thumbs together, their fingers open and their hands crossed when entering the water, with their palms facing the water. In addition, there are two unusual hand types: one is that the five fingers are open, and the two hands are kept at a distance of about 10 cm; the other is that the two thumbs are clasped, the fingers are bent and the palms are facing the water.

　　posture

　　Splash suppression is not just about hands.

　　Yu Fen told the Beijing Morning Post that the hand shape is only one of the details of the entry action, but it is not the only criterion to judge the entry effect, which determines that the entry action needs a series of essentials.

　　"Simply put, the athlete’s body should enter the water perpendicular to the water surface. The specific requirements are that the arms should be close to the ears, and the head, shoulders and toes should be in a straight line. At the moment when the palm touches the water, the body should be in a straight line of 90 degrees with the water, and the waist should not be loose, and the buttocks should be clamped. Sometimes you can see athletes appear when they enter the water ‘ Passed ’ Or ‘ Not enough ’ Phenomenon, the water is very big, and the completion of the branch is very low. The reason for this phenomenon is not necessarily that the water entry technology is not done well, and problems often appear in the air. The specific reasons need to be analyzed in detail. "

　　In fact, when entering the water from a 10-meter platform, the instantaneous speed reaches 15 meters per second. Because it is difficult to completely stop the rotation of the body in the air when entering the water, the palm needs to adjust its direction, not just parallel to the water. This is to avoid injury. Yu Fen introduced that on the basis of mastering the essentials, athletes also need to protect themselves through minor adjustments.

　　opportunity

　　Opening time affects the effect

　　"As mentioned earlier, there is a problem with the water entry effect, and we can’t just find problems from this link. As the last link in diving, the technique of splashing can really attract the attention of ordinary audience, but it is difficult to make it clear simply by talking about this link, just as athletes can’t just practice splashing. When they are training, if there is a problem in one link, they will have to re-enter the springboard or platform, and all the processes will be repeated. "

　　Yu Fen introduced that the whole process of diving is divided into seven links from the beginning of the athlete’s running platform or walking board to the end when the toes are completely below the water surface. "They are all interlocking. If one link is not done well, it will directly affect the back until it enters the water." Although when watching the diving competition, I sometimes hear the commentary mention that "the splash effect is ok, and it can be somewhat remedied", but judging an action, flaws and mistakes still cannot escape the eyes of the referee.

　　"Every movement has to go through thousands of exercises before it can be polished to the best. Before pressing the spray, the forming time of the action is also very important, which is what we call ‘ Open the opportunity ’ If it is opened too early, the athletes will stay in the air for a long time and cannot concentrate their strength completely; If it is too late, there is no time to adjust your body to the best position angle. "

　　give a mark

　　The referee won’t just stare at the splash.

　　Similarly, the referee’s score should also be based on the whole process of the diver’s completion of the action. "Not to say that in the end, the referee will give him points. (The splash is not pressed well) it does have an impact, but if the air attitude and the angle of entry are well done from the beginning of the take-off, this action can still be considered successful and the score can still be higher. "

　　There is an important message in the scoring of diving rules: the judge will evaluate the score according to the athlete’s run-up (i.e., running board and platform), take-off, air and water entry, and also explain the integrity of the scoring process. Therefore, athletes should run smoothly during the competition, take off decisively and forcefully, take off at an appropriate angle and with a certain height; Beautiful posture in the air, tumbling and turning quickly; When a person dives, his body is perpendicular to the water surface, and the smaller the splash, the better. Yu Fen said: "In fact, from the moment an athlete appears, the referee begins to score his temperament, including every detail of the completion of the action. From the training, we require athletes to do every detail in order to conquer the referee in the official competition. "

　　Introduction action "jumping popsicle"

　　It’s hard to dance well.

　　It is said that some people accidentally discovered in the "popsicle" diving that it is better to use the soles of their feet instead of stretching their toes, so they brought water impact’s splash pressing technology. And "popsicle" is just the enlightenment action of zero-based diving. You don’t need to stand upside down, just straighten up and jump into the water. This action is easy to say, and it takes time and energy to train it well. As Yu Fen, head coach of Tsinghua University Diving Team, said: Diving is a sport in which people exert their control over their bodies to the extreme.

　　The correct posture of "popsicle" diving is: standing in front of the platform, arms open and body in a T-shape; At the moment of jumping out of the platform, your feet should be off the ground at the same time, your arms should be lifted up and your body should be y-shaped; When entering the water, the arm should draw an O-shape in the air, and finally put the arm close to the thigh and enter the water. The whole action is completed in a few seconds, and you also need to control your body. In the star diving programs in the previous two years, the zero-based stars were in a lot of situations when they completed this basic movement, and even appeared "slamming the door", that is, the body slammed into the water. If you don’t control your limbs properly, you are most likely to break the door panel, causing bruises and redness. Some experts have analyzed that if you fall into the water from a 10-meter platform, it is equivalent to falling vertically from a height of 1 meter on the plastic playground.

　　At the same time, the stars participating in the program are all adults, and even tall models. The selection of materials for diving enlightenment training requires moderate height, small pelvis and light body. It was only after the full development that I began to contact diving, and the star diving program was really beyond my power.

　　On March 12 th, United Airlines has requestedStop producing the 737 MAX 10 aircraft for it, and switch to smaller models and Airbus A321 aircraft until the 737 MAX 10 passes the long-delayed certification.

　　United Airlines CEO Scott Kirby is on the 12 thThe investor conference said: "We have asked to stop manufacturing 737 MAX 10 for us, and they have already done so. We also asked Boeing to start manufacturing MAX 9 … When MAX 10 was certified, it is still uncertain. "

　　Kirby said that once the MAX 10 is licensed, United Airlines will switch back to using this aircraft. Kirby also confirmed earlier media reports that United Airlines is seeking to replace some of its 277 MAX 10 orders with Airbus A321 aircraft. (Bloomberg)

If the fruit circle is going to make a biography of Zhen Huan, then pineapples and pineapples will be the essential protagonists in this palace fight drama.

For a long time, the debate about whether they are the same fruit has never stopped. Open the search engine and enter the words "pineapple and pineapple" to find 5.95 million pieces of information.

You can find 5.95 million pieces of information by typing the words "pineapple and pineapple" in the search engine.

In the camp of "not the same fruit", supporters list the differences between pineapple and pineapple in every detail, for example, pineapple has fewer thorns, does not need to dig trenches, does not need to be soaked in salt water, and is more noble than pineapple (no, the pineapple party refuses).

The other camp believes that pineapple is actually a pineapple, and the two are like tomatoes and tomatoes, potatoes and potatoes.

So, what is the relationship between pineapples and pineapples on the market?

The dispute between pineapple and pineapple is actually an "infighting"

To understand this puzzle that has puzzled the fruit circle for a long time, we must first talk about the pineapple family.

According to the "Flora of China", the common name of pineapple is pineapple.

Botanically speaking, they are the same plant of the genus Bromeliaceae.

There are more than 2,000 employees in 45 genera in this "department" of Bromeliaceae, among which only one species of pineapple has economic cultivation value, and the rest have become ornamental flowers.

Potatoes, perennial evergreen herbaceous pulpy plants of bromeliaceae.

In 1935, there were 135 recorded pineapple varieties. According to the characteristics of fruits, they can be divided into four categories: Cayenne Group, Queen Group, Spanish Group and hybrid group.

If you go to a supermarket or a fruit shop to buy pineapple, you will probably buy a queen variety called Bali.

In 2015, about 80% of the main pineapple producing areas in Chinese mainland were cultivated in Bali.

Its leaves are a little prickly, and it will prick your hand. If you cut it open, you will find many black round fruit eyes, which are actually the stigma and stamens left in the pulp of pineapple.

After removing them, you can eat only about 57% of the pulp.

If you are persuaded by Bali pineapple and want to switch to "pineapple", then the clerk may recommend some special varieties to you, such as golden diamond pineapple, perfume pineapple, peeled pineapple and so on, but they are actually different members of the pineapple family.

Take Golden Diamond Pineapple as an example, it is a hybrid variety bred in Taiwan Province area, numbered Tainong 17. In 2018, 85% of the pineapples cultivated in Taiwan Province were golden diamonds.

Its size is one or two times larger than that of Bali, but its fruit eye is only half as deep as that of Bali. After cutting the peel, it can be eaten directly, with a crisp taste and overflowing juice.

Because the bromelain content in golden diamond pineapple is relatively low, it won’t sting too much when eaten.

However, its excellent taste and quality also mean that you need to pay more money to take it home. For example, in Baiguoyuan, a chain fruit shop, the price of an A-grade Bali pineapple is about 13.5 ~ 15.8 yuan/kg, while the price of a golden diamond pineapple of the same level is 42 ~ 45 yuan/kg.

　　BEIJING, Beijing, July 29 (Xinhua) Recently, many provinces intensively announced the written test results of the 2022 civil service provincial examination. With the release of the written test results, some provinces also concentrated on the violations of disciplines and regulations of candidates investigated in the civil service examination. Many candidates intend to cancel the test results, and some candidates are restricted from applying for civil servants within five years.

　　The written test results of civil servants’ provincial examinations are intensively released.

　　From July 9 to 10 this year, more than 20 provinces across the country held the 2022 written civil service recruitment test. In some areas, the scale of civil service recruitment this year has expanded compared with previous years. Due to factors such as the postponement of the test and the increase in the enrollment scale for fresh graduates, the news about the results of the written civil service provincial examination this year has also attracted much attention.

　　In the past few days, more than ten provinces such as Hainan, Ningxia, Henan, Hebei and Shaanxi have intensively announced the written test results of this year’s civil service provincial examination, and the news of the provincial examination has frequently appeared on the online hot search list.

　　With the announcement of written test results, many regions have also announced the qualification review and interview time. For example, on July 27th, Hubei Province announced the written test scores and minimum qualified scores of provincial examinations, completed the qualification review before July 31st, and organized interviews from August 5th to 7th.

　　The interview of civil servants in Henan will be held from August 2 to 5, and the interviewees will be determined according to the ratio of the number of positions to the number of interviewees of 1: 3, and the written test scores will be determined from high to low. Those who have missed a subject, cheated or scored zero in the written test, and failed to reach the minimum qualified score, are not allowed to enter the interview.

　　The answers are the same, carrying cheating equipment, and investigating and dealing with disciplinary candidates.

　　With the release of the written test results of the civil service examination, some areas have also exposed the violations of discipline and discipline investigated during this examination and marking.

　　On July 18th, Hainan Provincial Examinations Bureau published a list of 50 candidates who violated the rules and regulations in the public examination in official website and their handling opinions. According to the announcement of disciplinary action against civil servants’ examination, there are 50 candidates in Hainan provincial examination who have violated disciplines and regulations in subjects such as administrative professional ability test, township application, public security major, etc., and it is planned to treat the relevant candidates with zero test scores.

　　These candidates’ violations of discipline and discipline include "continuing to answer questions after the end of the exam signal is issued", "the contents of the answers are the same" and "marking my information outside the prescribed position".

　　In Hubei, on July 21st, Hubei Provincial Civil Service Bureau and Hubei Provincial Personnel Examinations Institute successively issued two announcements on how to deal with violations of rules and regulations of civil servants’ written test takers, and planned to deal with violations of rules and regulations of 75 people.

　　Among them, 73 candidates have violated the rules and regulations or have been identified as candidates with the same answer sheet, and it is planned to give them "the treatment that the test score of this subject is zero"; Two candidates were found to be in violation of discipline and discipline, and it is proposed to cancel the qualification of this examination and limit the handling of applying for civil servants within five years.

　　On July 22, Shaanxi Personnel Testing Center also released the handling of candidates who violated the rules and regulations in the written examination of the provincial examination, and gave 56 candidates who had general violations of the rules and regulations "the examination results of this subject were invalid"; An applicant who carries "cheating equipment" in the examination room is given the treatment of "canceling the qualification of this examination and restricting the application for civil servants for five years"; For the 32 applicants who failed to approve their identity according to the regulations during and after the examination, the scores of related subjects will be 0.

　　What will civil servants face when they break their promises in exams?

　　For the handling of civil servant examination violations, the new version of the "Measures for Handling Civil Servant Recruitment Violations" issued by the Central Organization Department and the Ministry of Human Resources and Social Security in September last year has detailed provisions. Among them, the behavior of "the test score of the subject (session) involved is zero" includes bringing items beyond the regulations into the examination room, failing to put them in the designated position as required after being reminded, failing to take the test in the designated seat, and continuing to answer questions after the test end signal is issued.

　　The disciplinary actions of "canceling the qualification of this examination and restricting the application within five years" include copying other people’s answer information or assisting others to copy answer information, viewing and eavesdropping on the text, audio-visual materials related to the examination brought into the examination room in violation of regulations, and using communication equipment or electronic equipment with calculation and storage functions that is prohibited.

　　Of course, there are also lifelong restrictions on taking the exam, including using forged, altered or stolen other people’s identity cards, admission tickets and other supporting materials to take the exam, taking the exam instead of others or letting others take the exam instead of themselves, illegally invading the exam information system or illegally obtaining, deleting, modifying and adding system data.

　　It is worth mentioning that for the identification of "identical papers", according to the provisions of this document, candidates who answer the same subject are identical in content and have other relevant evidence to prove that their cheating behavior is established, or may be given the treatment that they are not allowed to apply for civil servants for five years until life according to specific circumstances.

　　In fact, before the written examination of this year’s provincial examination was held, many provinces specifically mentioned the handling of identical papers in the pre-examination reminders. For example, Shaanxi reminds candidates before the exam. After the exam, technical means will be used to identify the same answer sheet. Those who are identified as the same answer sheet will be given invalid examination results, and will be dealt with according to relevant regulations according to the circumstances. Those who are plagiarized by others in the exam are judged to have the same answer sheet at their own risk. (End)
