Original Pudong CDC U Health

Seeing that this week’s working day is over half.

Do you have endless meetings every day?

And endless ppt

Still replying to work WeChat after work.

Often feel a kind of unspeakable fatigue?

This shows that your concentration of "Banwei" has exceeded the standard!

What exactly is "Banwei"?

Xiao u believes that the "class smell" related to health is to describe a sense of fatigue that is hard to dissipate when going to work.

From the perspective of traditional Chinese medicine, it is the sub-health state of the body caused by high-intensity work mode and job burnout, which is mainly manifested in the symptoms of strong liver fire, disharmony between spleen and stomach, stagnation of qi and blood, lack of yang, dry eyes, shoulder and neck pain, etc., similar to the "five strains and seven injuries" in traditional Chinese medicine.

Don’t underestimate this "class flavor"

According to a survey by the World Health Organization, about 75% of the people in the world are in a sub-health state.

Bad behavior, diet and mood caused by work pressure will have an impact on health. Without restraint and coordination, qi and blood will be blocked, bones and muscles will be damaged, and five internal organs may also be damaged.

Today u takes you to use Chinese "medical beauty"

Moist spirit goes to "class taste"

Restore one’s vitality

Acupoint massage

01

ocular region

Facing the screen of computer and mobile phone for a long time, your eyes are often dry and sore, which shows that your eyes are overtired!

Pressing and kneading specific acupoints around the eyes can dredge the meridians and relieve fatigue quickly.

Commonly used acupoints: Tianying, Yuyao, Temple, Sibai, Cuan, Sizhu, Jingming and Chengqi.

02

Shoulder neck

Working at my desk all day and playing with my mobile phone, the "rich bag" is getting bigger and bigger, and my shoulders and neck are getting stiff.

Remember to exercise your shoulders and neck properly every hour or so.

Holding Jianjing point can effectively relieve shoulder fatigue; You can also tap the Dazhui point for 5-8 seconds each time and repeat it for 3-5 times, which is helpful to dredge the neck meridians and relieve pain.

03

waist

Commuting for a long time in the morning and evening, sitting in the office for a long time during the day, crossing your legs for a long time, and your iron waist can’t stand it!

Pressing and rubbing Shenshu points on both sides with both hands has the effects of tonifying kidney, benefiting qi and strengthening waist and knees;

Massage on Weizhong point can dredge meridians, dissipate blood stasis and promote blood circulation, and relieve symptoms such as waist pain and lower limb radiation pain caused by lumbar disc herniation.

Press for 3 ~ 5 seconds each time, lasting for 3 ~ 5 minutes.

Eight-deficiency method

Eight Deficiencies refers to eight parts of the human body where pathogenic factors of zang-fu organs are most likely to gather-two armpits, two cubits’ nests, two groins and two popliteal nests. Frequent slapping helps to dredge meridians and regulate qi and blood.

During the break, pat each part with your palm or meridian hammer from top to bottom for 5-10 minutes until it is slightly hot.

Timely regimen

Winter diet should be based on warm food, such as mutton, walnuts, red dates, etc., which is helpful to the storage of yang in the body; It is not advisable to eat cold food, such as cold drinks and cold dishes, so as not to damage the yang of spleen and kidney;

Eat less spicy, greasy and irritating foods to avoid excessive consumption of body fluids.

Emotional conditioning method

Traditional Chinese medicine believes that emotion is closely related to the function of five internal organs.

Winter corresponds to the kidney, so it is extremely important to maintain the kidney, and the kidney can be full of energy and quick thinking.

In addition, the decrease of sunshine in winter is easy to cause anxiety, depression and other negative emotions. We should treat external changes with a normal heart, keep a good mood and be a person with stable emotions.

More sunshine, moderate exercise and slight sweating are appropriate.

You can choose Tai Ji Chuan, Baduanjin, jogging, yoga and other soothing exercises to relieve the anxiety caused by "class flavor".

Xiao u thinks

Moderate balance between work and life

Is to find a good medicine to remove the "taste of class"

I hope everyone can do it.

Original title: @ migrant workers, what should I do if the "class flavor" is too heavy? Teach you a few tricks to "taste the class"

　　Since modern times, there have been many arguments about how to treat Chinese and western cultures. More than 100 years ago, some people doubted or even denied their traditional culture when they saw that the western countries were gaining strength and expanding everywhere. They thought that everything in the west was good and they were inferior to others everywhere. Some people hope to learn from the strengths of the West and keep their own traditions, and put forward "learning from the West is the body, learning from the West is the use" or "learning from the West is the body, learning from the Middle School is the use".

　　Differences between different cultures do exist, and we need a rational understanding of these differences. It should be noted that we can’t just look at the cultural differences from the stage of development. This difference is mainly manifested in that some cultures develop first and some cultures develop later. We should also see that there are also differences in types between different cultures. Different countries and nations in the world have different geographical environments, different historical processes, and different institutional mechanisms and customs, so it is not easy to form the same kind of culture. These different cultures have different characteristics and styles, but they are all part of a hundred gardens of human civilization. The General Secretary of the Supreme Leader pointed out: "Human beings are only different in color and language, and civilizations are only different in color, but there is no distinction between high and low." This provides a fundamental basis for us to understand the differences between civilizations.

　　Because some western countries take the lead in opening the modernization process, some people think that western civilization is a model for the development of civilization. However, some late-developing countries copied the development model of western civilization, and as a result, they did not embark on the road of modernization. On the contrary, they fell into political turmoil and social unrest. In modern China, many people with lofty ideals explored the road of saving the nation and trying to imitate the West in terms of system and concept, but they all ended in failure. From a cultural point of view, it is difficult to blossom fragrant flowers and bear sweet fruits if two different types of cultures are grafted together stiffly. The heavy responsibility of history falls on the Communist Party of China (CPC). the Communist Party of China (CPC) people find Marxism, resolutely oppose historical nihilism and cultural nihilism, and combine the basic principles of Marxism with China’s concrete reality and Chinese excellent traditional culture, which not only makes Marxism have distinctive China characteristics, China style and China style, but also promotes Chinese excellent traditional culture from tradition to modernity.

　　After the end of World War II, great changes have taken place in some developing countries, which not only got rid of colonial or semi-colonial status politically and achieved independence, but also made great progress economically. This change in economic, political and social situation has prompted developing countries to think about their own cultural traditions, inspire cultural self-esteem and self-confidence, and more consciously protect their own cultural traditions and build modern culture. As far as China is concerned, since the founding of New China, especially since the reform and opening-up, it has taken us decades to complete the industrialization process that western developed countries have gone through for hundreds of years, creating a miracle of rapid economic development and long-term social stability, and successfully opening up the road to Socialism with Chinese characteristics. General Secretary of the Supreme Leader pointed out: "With the reform and opening up, with the establishment of the correct Socialism with Chinese characteristics Thought and the socialist road, and with the fact that this road is correct in practice, cultural self-confidence will follow." In the new era, we see that Socialism with Chinese characteristics and the Chinese Dream are deeply rooted in people’s hearts, the core values of socialism are widely promoted, the excellent traditional Chinese culture is loved by more people, and people’s cultural self-confidence is constantly revealed.

　　If the differences in the development level of science and technology and productive forces can be caught up and even eliminated through conceptual changes and social changes, then the differences in cultural types cannot be solved by "catching up", and it is impossible and unnecessary to solve them. A country and a nation must have cultural subjectivity if they want to walk out of their own modernization road. Cultural subjectivity is the premise of cultural self-confidence, and cultural self-confidence is an important embodiment of cultural subjectivity. General Secretary of the Supreme Leader pointed out: "Cultural self-confidence comes from our cultural subjectivity." During thousands of years of historical inheritance, Chinese civilization has always maintained the continuity of civilization records and formed the unity of pluralism, unity and concentration. After long-term exchanges and exchanges between various ethnic groups, you have me and I have you, showing the commonality, integration and centripetal subjectivity of social and cultural life. The Chinese nation is taking a road of civilized development different from other countries and nations. Chinese excellent traditional culture nourishes the sustainable development of the Chinese nation. The Communist Party of China (CPC) promoted the "two combinations", which further consolidated the cultural subjectivity. With cultural subjectivity, the Chinese nation and the people of China will have a solid cultural foundation of national identity, and they will be able to stand firm in the fierce world cultural agitation and go their own way independently.

　　Of course, this does not mean that there is no need for communication between different types of cultures. In fact, since ancient times, different types of cultures have been communicating. General Secretary of the Supreme Leader pointed out: "History tells us that only through exchanges and mutual learning can a civilization be full of vitality. As long as we uphold the spirit of tolerance, there is nothing ‘ Clash of civilizations ’ Civilization and harmony can be achieved. " Chinese said: "If you are good, you will also enjoy the goodness of others." If you can, you can also enjoy the ability of others. " "Each is beautiful, the beautiful people are beautiful, and the United States and the United States share the same goal." These reflect a mind of mutual appreciation, coexistence and common prosperity. Civilizations of different countries and nations are rooted in the soil of their own nations and have their own characteristics, strengths and advantages. Different civilizations should adhere to mutual exchanges, learning from each other and learning from each other, instead of being separated from each other, mutually exclusive and replacing each other, so that the world’s civilized gardens can be colorful and full of vitality.

　　Learning alone without friends is ignorant. In the long historical process, Chinese civilization embraces the whole world, harmonizes all nations, learns from others and is eclectic with its broad mind. We firmly adhere to the cultural subjectivity, and with a broad mind, draw on the outstanding achievements of civilizations created by different countries and nationalities, conduct cultural exchanges and cooperation with other countries in the world, and build the modern civilization of the Chinese nation with greater confidence.

Stills of "24 seconds of youth"

1905 movie network news From Stephen Chow to Jay Chou, from "Cyclone Girl" to the hit "Spray after Spray" this summer, there are more and more film and television works about sports, and people are paying more and more attention to sports. However, at present, the IP of sports theme in China has not been fully developed, and there are few dramas about football and basketball. However, at the end of this summer, a basketball movie will be released, which is also called the China version of "slam dunk". The film is directed by Ji Gang, and co-starred by Huang Junjie, Wei Late Autumn, Yan Luxian, Luo Jiaying, Yu Jia, Zhang Meie, Chen Cheng, Li Guanxing, Zhong Zheng, Zhou Ningning and Lu Tingyu. It will be released nationwide in October, opening an exciting bloody basketball game.

　

Luo Jiaying and the two supporting actors in the movie "Little Meat Star" are happy to get together.

　

Movies with the theme of pure love of youth have blossomed everywhere, and the audience is inevitably tired of vision. However, the theme film of youth inspirational blood sports is a new breakthrough of youth series movies, which includes youth after 00, longing after 90, dreams after 80 and nostalgia after 70, and is the new direction of youth movies in the future.

　

As a passionate youth film, the casting of "24 Seconds of Youth" has also been truly young. A 98-year-old sports man starring Huang Junjie is not only handsome in appearance and standard in figure, but also has a strong talent for acting, and he is born to eat this bowl of rice from actors. In addition, this film also gathers two classic supporting roles in Xingye’s films, one is Luo Jiaying in the movie, and the other is Zhang Meie in the movie. The gathering of two powerful actors will definitely add more comedy effects to the film.

Stills of "24 seconds of youth"

No emotion, no affectation. China needs such a youth movie.

　

Due to the convergence of themes, shoddy workmanship, consumer feelings, worrying acting skills and other issues, the difficulties faced by domestic youth films are becoming more and more serious. The publicity team knelt down to arrange films, and the movie protagonist hyped romance, which made the film divorced from the content itself. The film "Twenty-four Seconds of Youth" did a good job without gimmicks. The film used a vivid basketball story to combine brotherhood, inspirational growth and love between men and women, and skillfully made a new exploration from its own content by integrating the "24-second rule on the basketball court". The film extracts dramatic elements from daily life, tries to be grounded and resonates with everyone. In the past, symbolic modes such as fighting, abortion and money worship were not the audience’s imagination of youth. Therefore, the goal of this film "24 Seconds of Youth" is to "convey positive energy youth", without sensationalism, without "sadness flowing into the river" and without forced jokes. This is the correct way to open a youth film, and the China film market needs such a youth film.

　

Youth inspirational film "24 seconds of youth" will be released in October, so have a basketball game with your youth!

The change of screen

At present, the mainstream film projection form is "reflective imaging". Previously, it was film, which was recorded on coke film. After digital words, the image picture is that the image signal is driven by the corresponding processing circuit to form an optical signal, which is focused by the lens and then presented on the medium. The screen is such a medium.

　

In the early days of the film, white walls and white cloth served as imaging media. The projector is aimed at a white wall/cloth and projects the image onto the white wall, so the rough and original image appears in front of people.

The surface of the white wall is rough, and the white cloth is a little better but still not delicate. Their light reflection is "diffuse reflection", which can be reflected evenly in the range of 180. However, as a cinema, the included angle between the screen plane and the seating area is less than 180 degrees, usually the maximum included angle is only 60-90 degrees, which means that there is no way to use the light beyond the included angle, and the reflected light cannot be greater than the incident light. Therefore, the effective brightness gain of white walls and white cloth as screens cannot reach 1. Moreover, because the optical properties of white wall and white cloth can’t be controlled, but the optical properties greatly affect the image quality, so white wall and white cloth are not ideal film imaging media.

So a professional "screen" came into being.

　

Manufacturers apply coatings on the curtain base, such as barium sulfate or metal powder, as well as reflective screens made of glass beads and transmissive screens made of translucent materials. At present, the widely used metal screen, that is, spraying a layer of metal material on the screen base to enhance the reflection performance and polarization characteristics of light, creates a brand-new image reflection medium compared with the traditional white screen, reasonably improves the technical performance of the screen, such as brightness gain, and greatly improves the imaging quality of the screen.

　

Improvement of technical indicators

　

There are many technical indexes to evaluate the screen, and the common optical performance indexes include brightness, clarity, reflection angle, color, resolution and so on. Different screens present different picture quality, the fundamental reason is that the screen indicators are different. Indicators closely related to screening are as follows:

　

1. Brightness coefficient

That is, the "gain" that everyone knows in the industry is also the most representative indicator of the screen.

　

2. Effective scattering angle 2α

The effective scattering angle 2α of the screen is twice the maximum horizontal viewing angle α at which the screen reflection brightness is based on the brightness value of 5 viewing angle, and the brightness drop is not more than 50%. The measurement of this angle is based on the screen normal, with α on one side of the normal and 2α on both sides. Usually, "scattering angle" is used instead, and the larger the effective scattering angle of the screen is, the better.

　

3. Sound attenuation

The sound attenuation caused by the speaker located behind the screen of a transparent screen is defined as the difference between the sound attenuation of 8KHz and 12.5KHz and the sound attenuation of 500Hz, which is not more than 3dB and 6dB respectively. This item is easy to be ignored, especially the application of microporous screen will be more and more. Whether the diameter, spacing arrangement and perforation rate of sound transmission holes meet the requirements, reduce sound attenuation and ensure clear and realistic sound.

　

3. Color of reflected light

Screen surface requires good color reducibility, that is, the color chromaticity of reflected light and incident light should be consistent. The color temperature difference between the incident light and the reflected light on the screen shall not be greater than 200k K. This indicator is easy to reach the standard on the screen, but what needs attention is the color chromaticity of the incident light.

　

4. Resolution

The current definition, which we express in "pixels". The film age is represented by "line pairs". The screen used for projecting movies should have a projection resolution of more than 80 line pairs/mm. According to the resolution of the current screen, the resolution that can be displayed can exceed 4K or even reach 8K. (It will be explained in detail in the related article "Clarity". )

　

6. Screen material and coating uniformity

The material and coating of the whole screen should be uniform, and the uniformity of brightness distribution should be not less than 80%. This item can best reflect the attitude and process maturity of screen manufacturing, and the surface of unqualified screen products can be distinguished by naked eyes, such as stripes, spots and irregular shadows.

Of course, including the screen.Technical index of physical performance. The progress of modern screen technology revolves around these two parts.

for exampleBrightness aspectThe higher the brightness gain, the more concentrated the light reflected by the screen will be, which will produce the effect of bright in the middle and dark around. At this time, we call it "brightness uniformity" decline. From the technical principle, the brightness gain and brightness uniformity of the screen are a pair of contradictory terms, which cannot be well taken into account. Therefore, the progress of technology lies in obtaining higher brightness gain on the basis of higher brightness uniformity.

Therefore, many screen manufacturers are trying to improve this performance. For example, the film star screen improves the formula of reflective coating and introduces a 2.8 gain product, which makes the screen have both higher gain and larger effective scattering angle, and obtains better brightness uniformity in practical use and improves the picture quality. For the audience, it is that no matter which area in the cinema, uniform image brightness can be obtained.

Indicators and application scope of "movie star" screen (table)

　

Such as light reflection efficiency. The reflectivity of the screen is the ratio of the light projected by the projector to the intensity of the reflected light on the screen. The reflectivity of 50% means that half of the light is lost. In the past, the reflectivity of ordinary metal curtain was about 50%, but the newly developed screen has obviously improved the reflectivity, reaching more than 85% or even more than 90%. Compared with the traditional screen, the new screen makes the light reflection of the screen more controlled and has no stray reflection by reducing the sound transmission aperture, improving the coating arrangement and adding optical microstructure.

　

Another example is the polarization ratio. The polarization ratio of the screen is also one of the important indicators to eliminate ghost. If the polarization ratio is insufficient, the ghost will be heavier. Generally, the partial direct ratio of ordinary metal screens is required to be above 150:1. Nowadays, high-end screens have a polarization suppression ratio of over 500:1. It is not easy to feel the existence of ghosts.

In terms of physical performance, there are mainly the following indicators:

1. Aperture and perforation rate.

Before the screen, there were large sound holes, mainly to ensure the sound efficiency and frequency of the speaker behind the screen. In the era of digital movies, when the pixel size of 2K-definition movies is in a certain proportional relationship with the size of sound transmission holes, "moire" will occur. If you want to reduce moire, you can only destroy the above proportional relationship. Therefore, reducing the aperture of the screen has become one of the ways. At the same time, in order to improve the reflectivity, it is also necessary to consider changing the perforation rate while reducing the aperture.

For example, the aperture of the ultimate screen is only 150 microns, and the "movie star screen" can be mass-produced in almost unlimited size by continuously improving the processing equipment and technology of seamless splicing 0.6mm At the same time, the perforation rate can still reach 4.5%, which is not blindly reduced, fully ensuring the advantages of sound attenuation, but visually reducing the interference of sound-penetrating holes to a very low level and achieving excellent balance.

2. Screen size and strength.

As the picture of the film changes, the size of the screen also changes.

At the beginning, the aspect ratio of the movie screen was 1:1.33. After the wide-screen movie appeared, the aspect ratio of the screen increased to 1:2.35. The aspect ratio of the covered film is 1:1.85, while the aspect ratio of the IMAX giant screen is 1:1.44. In the digital age, the aspect ratio of the picture has changed slightly, with the ratio of wide screen being 1:2.39 and IMAX giant screen being 1:1.78. At the same time, the screen size is getting bigger and bigger, and the width is expanded from six or seven meters to twenty or thirty meters.

The size of the screen is a great test of the production strength of manufacturers. At present, there are two technical solutions, one is vertical, that is, the factory building has to be higher than the screen height, and the screen is hung vertically for machine spraying; The other is horizontal spraying, and the domestic "movie star screen" has the real production capacity of vertical spraying of super giant screen with a width of 100 meters and a height of 25 meters.

With the increase of screen size, the tension requirement of screen is increased, which puts high demands on the strength of screen, especially the splicing strength and effect. The strength requirement also includes the edge strength of screen hanging. As far as the intensity of screen base is concerned, one of the effective ways to reduce the speckle of tricolor laser is to vibrate the screen, and long-term vibration will undoubtedly put forward requirements for the intensity of screen base.

Nowadays, with the use of nano-new materials made of PET, the physical properties of the screen have been greatly improved. Under the conditions of heat, moisture and tension, the deformation of the screen is very small, and there is almost no relaxation damage after long-term vibration, which is more durable.

3. Splicing technology.

Because the screen is not produced as a whole, it is formed by splicing, so the splicing process of the screen also affects its performance. Good splicing should have a certain strength and be invisible at a certain distance. As a professional screen product provider, Wuhu Movie Star Giant Screen Co., Ltd. improved the screen seam technology through technical reform, so that the seam could not be seen at a distance of 1 meter in front of the screen, far exceeding the national standard.

4. Foldability.

In the past, most screens could not be folded, which meant that they had to be assembled in a drum, which was inconvenient for transportation, storage and hanging. Nowadays, the folding of nano-material screens has been improved, resulting in a number of foldable screens.

　

Important note:

　"Why are the pictures in the cinema more and more colorful?"

"Because the post-production is excellent." -that’s not the point.

"Because the performance of the projector has improved." -this is on the one hand.

"The performance of the imaging terminal screen has been continuously improved. 。” -this is the positive solution.

Therefore, paying attention to screen selection and protecting the screen needs more attention and professionalism.
