　　On July 1st, the Japanese government, which just finished the G20 reception, suddenly announced that it would restrict the export of three kinds of semiconductor materials to South Korea. According to Reuters’s report, Japan may impose this sanction as early as July 4th.

　　On the afternoon of the same day, the first official (deputy minister) of the South Korean Foreign Ministry, Zhao Seung-young, summoned the Japanese ambassador to South Korea and protested to him. South Korea’s Minister of Industry, Trade and Resources Cheng Yunmo said that he would consider resorting to the World Trade Organization.

　　According to the analysis of Nikkei Chinese Network, the semiconductor materials involved in this sanction are all materials for making TV and smart phone components. Japanese suppliers have an absolute dominant share in the market of these materials. Once the sanctions take effect, it will be difficult for Korean buyers to find alternative supply channels in the market, which will inevitably bring potential impacts to companies such as Samsung and LG in South Korea, and may also affect some Japanese manufacturers, which will have huge side effects in the long run.

　　At the moment when South Korea’s economic performance is not optimistic, how much impact Japan’s sanctions will have on South Korea’s economy has become a concern of many parties. According to Yonhap News Agency’s report on July 1, the Ministry of Industry, Trade and Resources of the Republic of Korea said on the same day that due to factors such as semiconductor and sluggish exports to China, South Korea’s exports in June decreased by 13.5% year-on-year to US$ 44.18 billion, showing a downward trend for seven consecutive months, and the decrease rate reached a new high in three years and five months.

　　However, there are also views that Japan’s sanctions are rare, but they are not intended to make South Korea "hurt." Hu Lingyuan, director of the Center for Japanese Studies at Fudan University, believes that this round of diplomatic turmoil between Japan and South Korea can be understood from the perspectives of historical issues between Japan and South Korea and their respective domestic politics.

　　Sanctions and countermeasures are still measured, but the business community has begun to worry.

　　In addition to the semiconductor industry, according to the Nikkei Chinese website, Japan also plans to remove South Korea from the "white list" of friendly countries in security protection in August.

　　According to the above report, Japan will strengthen South Korea’s export control in two stages. First, after July 4th, three products, fluorinated polyimide, photoresist and etching gas (hydrogen fluoride), are required to be licensed and examined separately. And it is planned to exclude South Korea from the "white list" of friendly countries in security in August.

　　According to the report, the list includes 27 countries including the United States, Germany and France, and South Korea will be the first country to be eliminated. If it is not on the list, the products that may be transferred to the military need to be approved by the Japanese Ministry of Economy, Trade and Industry when they are exported, and electronic parts, precision parts, machine tools, etc. are all controlled objects.

　　However, although the volume is not small, it seems that the leaders of Japan and South Korea have no intention of completely "freezing" the relations between the two countries.

　　"The semiconductor industry is not a particularly sophisticated field. Abe beat South Korea in this field and expressed his dissatisfaction, which can convey a kind of ‘ I’ll punish you for doing something wrong ’ The signal. It’s like having a bad breath. " Hu Lingyuan said.

　　Regarding the export control this time, Keisuke Yusheng Tian, executive director of Deloitte Management Consulting Company in Japan, said that "since it is an area where Japan can make its own judgment, it is estimated that it will not violate the rules of the World Trade Organization". However, Professor Fuyong Youxia of Waseda University thinks: "This is a measure in a gray area suspected of violating WTO rules".

　　"In fact, after Japan took the initiative to sanction, South Korea was a bit passive. It seems to be a loss to overthrow the agreement before, and South Korea’s domestic economy is not performing well now. In order to lose points, the Moon Jae in administration must fight back against Japan. " Hu Lingyuan analyzed that "South Korea will take some retaliatory measures, but it will be restrained. In fact, Japan’s sanctions are also moderate. Both sides have a deep concern for their domestic people ‘ Show ’ The ingredients will not really cause particularly deep harm to each other. "

　　In fact, many international factors also restrict the severity of Japan-South Korea bad relations. Japan has just finished the reception for the G20 Osaka Summit, and seems unwilling to be too "high-profile" when imposing sanctions on South Korea.

　　"The reason why sanctions are announced now is because Japan does not want this matter to affect the G20 meeting." Li Kaisheng told The Paper, "When all countries are opposed to the unilateralism of the United States, as the host of the G20, Japan does not want to affect its image because of sanctions."

　　"In addition, Abe can’t make Japan-ROK relations too rigid, and we must grasp the balance." Hu Lingyuan analyzed and said, "On the one hand, Abe wants to make some noise, but on the other hand, he can’t overdo it. In that case, it is difficult to score in China."

　　At the moment when the situation on the peninsula is easing, the factors of the United States and North Korea are also variables that cannot be ignored when the Abe government makes decisions.

　　"Abe must also take into account the feelings of Trump and Kim Jong-un. Trump just met with Kim Jong-un. In the context of the easing of the situation on the peninsula, Japan also wants to improve relations with North Korea. In Kim Jong-un’s view, Moon Jae in’s efforts to improve North-South relations are relatively positive. Under this circumstance, if Abe is too tough on South Korea, Kim Jong-un will not feel very happy. " Hu Lingyuan said.

　　However, the industry has begun to worry about the follow-up impact of sanctions.

　　According to the Nikkei Chinese website, the relevant person of SK Hynix said in an interview that the inventory was "less than 3 months". When asked, "If we can’t purchase more, will the factory stop production in three months?", the answer was "Yes".

　　Samsung Electronics evaded the specific instructions and only said that it was "investigating the situation in detail".

　　On the other hand, however, Korean companies have a high market share in the semiconductor field. In terms of semiconductor sales, South Korea’s Samsung Electronics topped the list, while SK Hynix ranked third. Especially in the storage semiconductor for data storage, Korean companies have strong advantages. A large Japanese electromechanical company is worried that "if the supply of storage semiconductors in South Korea stagnates, which will lead to a reduction in the production of Apple’s iPhone, it may also have an impact on the supply of parts and components of the company".

　　Sanctions have obvious symbolic significance, and both sides focus on internal affairs.

　　"Japan chose the semiconductor industry to start, which is mainly a symbolic act. It is not that Japan and South Korea will soon be in the semiconductor industry ‘ Go to war ’ Yes. " Hu Lingyuan told The Paper (www.thepaper.cn), "Abe’s action is first considered for the Senate election in late July."

　　The Senate election to be voted on July 21st is the first parliamentary election in Japan since the era of "making peace". Abe attaches great importance to this election. According to Xinhua News Agency, Abe’s Liberal Democratic Party is continuing to seek to amend Article 9 of the Constitution, so it regards constitutional amendment as one of the focuses of the Senate election. One of the highlights of the election is whether the forces supporting constitutional amendment can continue to maintain a two-thirds advantage in the Senate. However, Japan’s Kyodo News reported at the end of June that there are currently 78 people in the Senate who support constitutional amendment without re-election, and Abe still needs to win the support of 86 people to form a two-thirds advantage. Therefore, it is difficult to cross the threshold of constitutional amendment as it was three years ago.

　　In addition, just on the 25th of last month, Shinzo Abe just faced a cabinet no-confidence resolution jointly submitted by five Japanese opposition parties, including the Constitutional Democratic Party. Although Abe successfully "passed the customs" with the majority opposition from the people, the two parties and the Japan Reform Association, Abe will still face many uncertainties in the face of the decisive battle of the Senate election to be held in late July.

　　In this regard, Hu Lingyuan analyzed that the election campaign is about to enter a climax. If the election is very beneficial to Abe at that time, it is not excluded that he wants to "bundle" the elections of the Senate and the House of Representatives at the same time, further consolidate his domestic status, and even serve as the fourth prime minister. Therefore, Abe has the motivation to use his relationship with South Korea to do some articles.

　　In addition, Abe’s appointment in the diplomatic field has recently been incompetent, so he intends to score points in diplomacy and win the favor of voters. According to Hu Lingyuan’s observation, Abe’s diplomacy with China has been relatively successful recently, and other directions are all promising.

　　"The G20 is going well, but Japan-US relations are not optimistic. Trump also mentioned the Japan-US security treaty, and the United States is expected to put pressure on Japan after the Japanese Senate election. " Hu Lingyuan said, "Russia has also found it difficult to break through Abe, with Putin ‘ Make friends with ’ It seems that the trick can’t be played anymore. Therefore, Abe’ s diplomatic pressure is still relatively large. "

　　Abe is not the only one facing internal pressure. Moon Jae in’s South Korea’s economic performance was mediocre, and the economic growth rate showed a red light. On April 2 this year, the data released by the Ministry of Trade, Industry and Energy of the Republic of Korea showed that after the export data in February shrank at the fastest speed in the past three years, the total national export of South Korea in March was 47.11 billion US dollars, down 8.2% from the same period of last year, and fell for four consecutive months since December last year. On the 9th of the same month, the International Monetary Fund (IMF) predicted the list of countries whose economic growth rate will decline this year, and South Korea was among them.

　　"The Moon Jae in government is facing great pressure in the economic field. They promised to increase welfare, but the economic data is not optimistic at all. " Song Zhixun, a 27-year-old Korean youth, told The Paper, "If you lose points in diplomacy, it will be very unfavorable to Moon Jae in."

　　Japan and South Korea are not in a cold day, and Japan is suffocating.

　　In addition to the internal factors of the two countries, for the Japanese and Korean people, Japan’s rare sanctions are not completely unexpected. The two countries have been feuding for a long time because of historical issues, and they are deeply divided.

　　According to the Kyodo News Agency, a joint survey conducted by Genron NPO, a Japanese non-profit organization, and the Institute of East Asian Studies (EAI), an independent think tank in South Korea, from May to June showed that more than 60% of the respondents in both countries said that they thought the bilateral relations between Japan and South Korea had deteriorated, while only 6.1% of Japanese respondents and 3.7% of Korean respondents still thought that the relations between the two countries were "good".

　　Compared with the same period of last year, the proportion of Japanese respondents who thought bilateral relations were "bad" jumped to 63.5%, an increase of 23 percentage points, the highest level since the first survey in 2013.

　　Kyodo News analyzed that one of the main reasons for the deterioration of relations between the two countries is the position of the Supreme Court of Korea on wartime workers. Japan insists that South Korea gave up the right to claim compensation in the 1965 Basic Treaty between Korea and Japan, and Japan provided huge funds for "economic cooperation" to South Korea, including grants worth 300 million US dollars and loans worth 200 million US dollars over 10 years — — The total amount was 1.5 times that of the national budget of Korea at that time.

　　In this regard, Naiwang Muxia, a Japanese college student, told The Paper that South Korea could not forget what Japan did as a colony during World War II, but Japanese officials believed that it had provided economic compensation to South Korea after the war, so they did not want this history to be mentioned again. "Japan (the government) feels that we have solved this problem with money. If South Korea wants Japan to listen to their claims, let’s return the money to Japan first." Naiwang Muxia said.

　　The survey also showed that another reason for the rapid deterioration of Japan Maritime Self-Defense Force-ROK relations was the incident that a South Korean navy destroyer irradiated a fire control radar on a Japanese patrol aircraft in December last year. According to the survey, more than 60% of the respondents in Japan and South Korea expressed confidence in the version of events provided by their governments. The Japanese side called the incident an "extremely dangerous act" and lodged a solemn protest with the ROK. The South Korean side explained that this was a normal combat operation, not aimed at Japan.

　　Based on the above-mentioned disputes, during the just-concluded G20 Summit in Osaka, Japan, the leaders of Japan and South Korea did not hold bilateral talks, but only shook hands and took a group photo as the host and guest at the opening ceremony.

　　"The historical issue has dragged on for a long time, and Japan really feels that it has a bite in its heart ‘ Evil spirit ’ . The Japanese side feels that park geun-hye has signed an agreement with Japan on ‘ Comfort women ’ The agreement on the issue, but now South Korea does not recognize it. " Hu Lingyuan explained.

　　The Japanese government believes that South Korea’s reopening of the issue of forced labor by the Japanese army during World War II violated the Japan-South Korea Claims Agreement between the two countries. Suga Yoshihide, the Japanese Chief Cabinet Secretary, rejected the proposal made by South Korea on June 19th, saying it was "totally unacceptable".

　　"In Japan’s view, since there is an agreement between the two governments, it cannot be said that the government will overturn the agreement as soon as the people are emotional. This makes Abe feel very faceless. " Hu Lingyuan said.

　　"In fact, it is understandable that Japan is a country with strong self-esteem." Song Zhixun, a 27-year-old Korean youth, gave his own understanding of the deterioration of relations between the two countries in an interview with The Paper. "They (Japan) are jealous of us as everyone knows, and (Korea) is obviously a colony of the former (Japan), but many industries and even cultures, stars and movies are occupied by South Korea. It must feel bad."

　　"Regarding Japan-ROK relations, there are two levels of government and people." Song Yue, director of the Korea Institute of East Asian Studies, who conducted the survey, said. On the other hand, Yasushi Kudo, the head of Genron NPO in Japan, also said that although most people think that Japan-ROK relations have deteriorated, the general impression of another country is not so bad. "Both governments should admit that their people want to improve this relationship." Kudo Jing said.

　　"We will hate the Japanese government, but we won’t hate the Japanese, especially the young people have no opinions on the Japanese." Song Zhixun said. Speaking of the trade sanctions that Japan has just announced against South Korea, Song Zhixun believes that this unfavorable situation for both sides will not last long. "It’s just temporary. (Japan and South Korea) was originally an alliance. In fact, there will be no reaction (relationship) no matter how bad it is."

　　Today, with the rapid development of science and technology, rumors under the banner of science are also emerging one after another. Moreover, many rumors like to start with the health and safety issues that the public cares about, sensationalize and create panic. A few days ago, under the guidance of the Beijing Association for Science and Technology, the Beijing Association of Editors of Science and Technology Journalists and the Beijing website jointly released the platform of dispelling rumors, "stop rumors and seek true knowledge — — Top Ten in 2019 ‘ Science ’ Most of the rumors in the gossip list are related to health. This edition extracts some health rumors and their truth interpretation and routine analysis to set the record straight.

　　Keywords: 5G base station radiation

　　● Gossip:

　　Mobile phone base stations have radiation, and 5G base stations are more than 4G, so 5G radiation will be greater than 4G, which is very harmful to human body.

　　● The truth:

　　Radiation is actually a way of energy transfer. Network speed-up has nothing to do with base station radiation increment. Network speed-up depends not on enhancing the signal transmission power of communication base stations, but on expanding transmission bandwidth, just like widening highways. The same is true for 5G communication base stations. Moreover, the more communication base stations there are, the better the effect of mobile phone calls, and the smaller the electromagnetic radiation generated between mobile phones and base stations.

　　The earth itself is a large magnetic field, and electromagnetic radiation is generated by lightning, thunder and sunspot activity in nature. In life, radio stations, base station antennas, microwave ovens, computers, televisions, hair dryers, radios and other household appliances that are inseparable from people’s lives will also produce electromagnetic radiation. Generally speaking, the radiation of the hair dryer can reach 100 microwatts/cm2, and the radiation of the induction cooker can even reach 580 microwatts/cm2. The wireless router commonly used in the home also generates more than 60 microwatts/cm2 within 1 meter.

　　The electromagnetic radiation of communication base stations should be less than 40 microwatts per square centimeter according to the requirements of national standards. In the actual implementation, the operator should consider the signal superposition, and the project construction should be controlled within 8 microwatts/cm2. Therefore, whether compared with national standards or common household appliances, the radiation of communication base stations is very small and will not cause harm to human body.

　　● Routine:

　　New things, exaggerated.

　　This kind of gossip takes advantage of people’s ignorance of new things and exaggerates them, so that rumors can be widely spread.

　　● Similar rumors:

　　1.PX is teratogenic, carcinogenic and highly toxic, and the explosion is comparable to an atomic bomb.

　　Truth: PX has a long history. It is a widely used low-toxicity chemical product and a raw material for medicine, perfume and ink.

　　2. Eating genetically modified food is childless, and Americans don’t eat it.

　　Truth: The safety evaluation of genetically modified food is much stricter than that of ordinary food, and the genetically modified food approved by the government is safe.

　　Keywords: high-speed rail radiation

　　● Gossip:

　　High-speed rail has had serious radiation problems since its birth, and the greatest harm to people is to destroy the female reproductive system and cause infertility.

　　● The truth:

　　Trains running on high-speed railways in China generally use 25,000 volts and 50 Hz alternating current. Accordingly, the high-voltage power equipment of high-speed rail radiates the electric field and magnetic field in this frequency band, which is "extremely low frequency electromagnetic radiation", belonging to non-ionizing radiation and will not affect women’s fertility. The statement that "high-speed rail radiation seriously causes infertility" is purely misleading.

　　Where there is electricity, there is radiation, ordinary trains and subways have radiation, mobile phones and razors have radiation, and sunlight also has radiation. As long as the radiation is within a safe value, it will not affect people. The International Commission on Non-ionizing Radiation Protection stipulates that the safety standard of magnetic field radiation generated by high-speed rail is below 100 micro Tesla (magnetic induction intensity unit), and the safety standard of electric field radiation is below 5 kV/m.

　　Professionals of Beijing Railway Department have specially measured the electric field radiation in high-speed rail cars and made the measured data public. The electric field radiation values of first-class cars, second-class cars, car joints, cabs and other positions of different models are distributed in the range of 0.011-0.021 kV/m.. Comparing these data, it is not difficult to find that the electromagnetic radiation of high-speed rail in China is far below international standards, and it is impossible to cause harm to human body.

　　● Routine:

　　Don’t talk about dosage, exaggerate the harm.

　　Alarming and exaggerating threats are the main characteristics of such rumors. Talking about radiation without dose has no practical significance in science. We have similar misunderstandings about many phenomena in life.

　　● Similar rumors:

　　1. Drinking coffee will cause cancer by ingesting acrylamide.

　　Truth: Acrylamide produced by high temperature in the process of making coffee is only potentially dangerous, and the content is very small. A person needs to drink at least 318 cups a day to have cancer risk.

　　2. The X-ray security instrument is harmful to human body.

　　Truth: The radiation of the security detector is far below the safety standard, so there is no need to worry about harm to the body.

　　Keywords: plague

　　● Gossip:

　　The mortality rate of plague is as high as 100%, and there is no cure. If you get infected, you will die!

　　● The truth:

　　Plague, also known as the Black Death, is a severe infectious disease caused by Yersinia pestis. According to different infection sites and clinical manifestations, plague can be divided into bubonic plague, pneumonic plague, septicemia plague, mild plague and other rare types of plague. Historically, plague did cause large-scale deaths, but it was because people didn’t know enough about the cause, treatment and prevention of plague at that time.

　　Although human beings are generally susceptible to plague, in modern medicine, plague is no longer hopeless. In fact, clinical plague cases can already be treated by standardizing the use of antibiotics. If patients can see a doctor early and get standardized treatment, the cure rate is very high, and suspicious contacts can also avoid getting sick by preventive medication.

　　However, it should be reminded that untreated plague patients have a very high mortality rate, such as the most dangerous pneumonic plague, which can be fatal within 18-24 hours of onset. If septic plague is not treated in time, the mortality rate is almost 100%. Therefore, early diagnosis and treatment are very important for patients to survive and reduce complications.

　　Gao Fu, academician of China Academy of Sciences and director of China CDC, said that at present, China has basically established a relatively complete prevention and control system. As long as it is scientifically responded, there will be no risk of widespread spread of plague.

　　● Routine:

　　In sensitive times, create panic.

　　Plague has caused heavy casualties in history, so related rumors spread rapidly when two cases of imported plague were found in Beijing. In the event of sudden events such as major epidemics and major disasters, people tend to be very sensitive and panic, and relevant rumors are easy to spread at this time. When dealing with extreme statements, we should develop the habit of questioning more.

　　● Similar rumors:

　　1. Sodium cyanide may cause toxic rain at the explosion site in Tianjin.

　　Truth: Solid sodium cyanide itself is highly toxic and can be dissolved in water, but it has no gaseous form in the conventional environment, so it is impossible to enter the air and spread with the wind, so there is no possibility of mixing with other components in the atmosphere and forming toxic rain by precipitation.

　　Smoking can prevent SARS.

　　Truth: It is recognized that smoking is harmful to health, one of which is to weaken the defense function of human respiratory system and increase the chance of infection. Besides, smoking also increases the contact between hands and nose and increases the chance of infection.

　　Eating iodized salt can prevent nuclear radiation.

　　Truth: The iodine content of iodized salt sold in the market is very low. In order to get the dose level required for the radiation protection of iodine, an adult needs to eat at least 2 to 3 kilograms at a time. Eating too much iodized salt or iodine tablets blindly according to the actual situation is harmful to the health and may cause diseases such as iodine exceeding the standard and iodine hyperthyroidism.

　　Keywords: thyroid nodules

　　● Gossip:

　　Detection of thyroid nodules is a precursor to thyroid cancer.

　　● The truth:

　　Generally speaking, most thyroid nodules are benign lesions, and real thyroid malignant tumors only account for a small part, so patients with thyroid nodules need not worry too much.

　　The diagnosis of thyroid cancer mainly depends on palpation, ultrasound, puncture and intraoperative pathology. With the continuous improvement of the resolution of modern ultrasound technology, more and more concealed papillary microcarcinoma of thyroid can be found, and most thyroid cancers can be cured through scientific and standardized treatment.

　　However, although there is no need to worry too much about thyroid nodules, we should not take them lightly. We need to go to a regular hospital as soon as possible for a definite diagnosis, so as not to delay the illness and miss the "golden time" of treatment.

　　In addition, because thyroid cancer usually has no obvious symptoms in the early stage, it is difficult to be detected. If there are symptoms such as sudden enlargement of nodules, dysphagia and adhesion of tissues near nodules, a comprehensive thyroid function test should be carried out to judge the nodules. Nodules that are difficult to distinguish should be examined regularly every 6 to 12 months.

　　● Routine:

　　Catering to demand, selling anxiety.

　　At present, people generally pay more attention to the topic of health and health preservation, but there are different opinions on online information, and some ambiguous rumors will take advantage of people’s psychological communication of "preferring to believe it, not believing it."

　　● Similar rumors:

　　1. There is rubbish in blood vessels, and if it is not cleaned up, it will be riddled with diseases.

　　Truth: There are no so-called garbage and toxins in blood vessels, but only metabolic wastes. Drinking plenty of water and increasing urination at ordinary times can help accelerate the cleaning of metabolic waste. In addition, any health food and detoxification soup can’t clear them out of the body.

　　2. Acidity is the root of all diseases.

　　Truth: The human body has an effective regulation system, which keeps the pH value basically stable and only fluctuates in a small range. In other words, eating any food will not change the pH value of the human body, and even drinking vinegar will not make the human body more acidic.

　　Keywords: artificial snow catalyst

　　● Gossip:

　　The large-scale snowfall in North China from February 13 to 14, 2019 was artificial snow increase. Silver iodide contained in artificial snow-increasing catalyst will endanger human health and cause environmental pollution.

　　● The truth:

　　In this snowfall, it is true that artificial snowfall has been carried out in some areas, but even if all the silver iodide catalysts used for snowfall have landed on the ground, the content of silver iodide per square kilometer is only 0.21g.. According to the precipitation, the silver ion concentration is about 0.000035 mg/L, which is far lower than the requirement of the World Health Organization standard and China’s national sanitary standard for drinking water that the silver content should not exceed 0.05 mg/L, and it will not pollute the ecological environment, and will not endanger human health.

　　As early as 1960s, scientific research institutions began to study the impact of silver iodide catalyst on the environment. The detection data of precipitation and soil after artificial rain and snow increase in the United States, Spain, Greece, Australia and Russia show that the average concentration of silver ions is very low. Therefore, the adverse impact of silver iodide, a catalyst used for weather modification, on the ecological environment can be ignored.

　　● Routine:

　　Technical terms lead to misinterpretation.

　　It is a common routine to take for granted the explanation of professional words that the public can’t understand, and spread it by taking advantage of people’s vanity that "I know more than you". Many people simply don’t know what "silver iodide" is, so they naturally believe and spread such rumors.

　　● Similar rumors:

　　1. Domestic salt contains potassium ferrocyanide, which is as toxic as arsenic.

　　Truth: Potassium cyanide is a well-known toxic substance, which is not the same as potassium ferrocyanide contained in salt. Potassium ferrocyanide is a low toxic substance, and a person needs to eat three or two salts a day to have a negative effect on the human body, while the salt that we normal people eat a day is already very salty when it reaches 20 grams.

　　2. Cereal contains pesticide glyphosate, which can cause cancer.

　　Truth: Scientific research shows that glyphosate has no negative effects on the development, reproduction and endocrine system of human beings and other mammals, and it has no chronic toxicity and neurotoxicity to animals in farmland within the scope of normal use.

　　Keywords: X-ray film

　　● Gossip:

　　X-ray has a great influence on human health, especially on pregnant women, babies and fetuses. Therefore, after taking the X-ray, I found that I was pregnant, so the child could not have it, and I had to have an abortion in time.

　　● The truth:

　　There is a threshold for the adverse effects of X-rays on all mammals, including humans, and even embryos. No matter for adults or fetuses, the radiation must reach a certain level to be damaged. Therefore, we can’t talk about the damage without the "dose" of radiation.

　　For the fetus, different gestational ages correspond to different safe doses of radiation. In 2017, the American Association of Obstetricians and Gynaecologists issued relevant guidelines: from 0 to 2 weeks of pregnancy, the threshold of teratogenic dose is 50 to 100mSv (millisieverts), and the main impact is fetal death; From 2 to 8 weeks of pregnancy, the threshold of teratogenic dose is 200mSv, and the main influence is congenital malformation; From 8 to 15 weeks of pregnancy, the threshold of teratogenic dose is 60 to 310mSv, which mainly affects mental development and deformity. Therefore, the threshold of the minimum influence dose of the fetus is 50mSv, which is safe as long as it does not exceed this value in theory.

　　In general, the radiation dose of an ordinary chest radiograph is 0.02mSv, that of a knee joint X-ray is 0.005mSv, that of a head CT is 2mSv, and that of a chest CT is 8mSv. Obviously, these radiation doses are within the safe range. To reach 50mSv is equivalent to 2,500 chest radiographs in continuous shooting, or 6 consecutive CT scans.

　　Many hospitals will take corresponding protective measures for those who are examined. For example, when taking a chest X-ray, the examinee will be put on a special lead hat and collar, and a heavy lead apron will be put around the waist and below to avoid unnecessary radiation to the human body.

　　● Routine:

　　Inertia thinking affects judgment.

　　In life, many medical institutions will remind pregnant women and pregnant people to avoid taking X-rays, which may make people form a "mindset", thus affecting rational analysis and judgment.

　　● Similar rumors:

　　1. The "grotesque" big strawberries are all hormonal.

　　Truth: hormones are substances that exist in plants themselves, and there is no need to talk about it. Most of the big strawberries on the market are "lucky" strawberries, which are very big in themselves. Some strawberries look strange, because the temperature and humidity conditions in the greenhouse are not good enough, and the lack of bees leads to uneven pollination.

　　2. Low outdoor visibility is caused by heavy pollution.

　　Truth: Atmospheric visibility is mainly affected by four factors: particle concentration, chemical composition, relative humidity and solar radiation. We often say that "air quality" only represents the concentration of particulate matter. In summer, the humidity of "sauna day" is relatively high, which significantly enhances the scattering effect of sunlight, resulting in a decrease in the amount of light input into people’s eyes, so the visibility is reduced.

　　Keywords: running

　　● Gossip:

　　People who run regularly are prone to hip and knee arthritis.

　　● The truth:

　　Risk factors leading to arthritis include age, family history, overweight and injury, but the length, intensity, distance and the number of long-distance runs completed have nothing to do with arthritis. In other words, people who are older, heavier, have a family history of arthritis or have had joint injuries are more likely to get arthritis.

　　Long-distance running does not destroy joints, but the proportion of marathon runners suffering from arthritis is lower than that of ordinary people. A large-scale study in 2017 showed that the incidence of arthritis in runners for fitness purposes was only 3.5%, while that in sedentary people was 10.2%. In other words, running can be a protective factor for the knee, and the key lies in the correct running mode.

　　In short, you should run within your power according to your physical condition. As long as the method is proper, it is beneficial to your joints and health.

　　● Routine:

　　Causality is confused and logic is misleading.

　　Misleading grafting causality. Succession or association is not equal to causality, and causality needs strict argumentation. It is a kind of thinking mistake that we often make to mistake the relationship of precedence or association for causality.

　　● Similar rumors:

　　1. Cold stimulation weakens the immune defense ability, and freezing can lead to arthritis.

　　Truth: By the age of 40, almost all people will have some pathological changes of osteoarthritis in their weight-bearing joints. Catch cold or catch cold is only an inducing factor that leads to the aggravation of arthritis symptoms, not a direct cause.

　　2. The woman in Xi ‘an died after being bitten by a dog and vaccinated, and the rabies vaccine was useless.

　　Truth: After the rabies vaccine is injected, there is indeed the possibility that the vaccine will be ineffective due to accidents, such as incomplete wound treatment and a small amount of virus remaining, but this does not mean that the vaccine is useless. In most cases, rabies vaccine is safe and effective.

　 1905 movie network exclusive feature In the screening of "Fast Shooter day trader" (hereinafter referred to as "day trader") on July 18th, Zi Shijun was surprised to find that you have one and only one choice to watch "day trader" in INDIGO store of CGV Studios, and that is the ScreenX field.

　 What is the "black" technology of ScreenX? I believe it is quite strange to many people. In fact, as early as March this year, Zi Shijun once revealed past lives, who showed new technology in this cinema (click here to review). To put it simply, it is to use the multi-faceted projection technology to project the film images to the left and right walls of the cinema, and then bring the audience a 270-degree ultra-wide-angle immersive viewing experience.

　 At the end of last year, "Searching for Dragons" was the first movie in China to eat crabs. At that time, the pre-sale was quite popular. Take the opening of Dalian Wanda Studios as an example, the average attendance rate of the film on the first Saturday was as high as 95.2%.

　 On July 15th, the ScreenX version of day trader, a fast shooter, was released for 70 minutes, the longest in history. Wei Cheng, which was released in August, is the first time to introduce ScreenX 3D into China movies.

　 How to unlock this new ScreenX viewing posture, which is called "three screens combined" and "270-degree viewing"? Zi Shijun made a special trip to interview Jin Tailong, general manager of 4DPLEX China, which is responsible for the business development of ScreenX under CJ CGV of South Korea, and Jin Shiquan, director of ScreenX of Fast Shooter day trader, to hear what they said:

[What did the ScreenX version of day trader say? 】

ScreenX’s special offer: a big scene near the scene, narrative "wheel array"

　 What kind of experience is it to watch "day trader the Fast Gunner" in the ScreenX Hall? Let’s start with the "X" in ScreenX:

Jin Tailong, General Manager of 4DPLEX China

　 In Jin Tailong’s understanding, "X" has three meanings. One is "Expand", which breaks through the boundaries of traditional screens and realizes the extension of space and vision; Second, "Express" (expression), the expansion of space, provides more space and possibilities for the innovation of film narration and expression. The third is "Experience", and the images surrounded on three sides give the audience a brand-new immersive viewing experience.

　 In "Fast Shooter day trader", ScreenX images are widely used in the desert scene in vast expanse, and the golden desert in Kazakhstan stretches out on the 270-degree screen of ScreenX, which makes the audience feel more immersive and makes the scenes of car chasing, fighting and explosion on it more thrilling and shocking.

　 In addition to the immersive viewing experience brought by the panoramic extension effect, another major feature of ScreenX is the use of side screens to increase the richness of narrative. As Paul Kim, the production director of CGV LA office, mentioned, "ScreenX is not only a technology, it should not exist without the narrative of the film, but should be part of the story."

　 Paying attention to the combination with the film story is also one of the reasons why the ScreenX version has not covered the whole film so far. "Compared with the ScreenX version that runs through the whole film, it is better to enter a paragraph, leave a paragraph, and combine it with the plot, so the effect is better," Jin Shiquan said.

　 In the ScreenX version of day trader, the Fast Gunner, three screens are often used to show different contents, characters or perspectives. For example, the screens on both sides are used to show the memory world or "brain hole" world of the main screen characters, or the side screens are displayed synchronously in the form of maps when the main screen hero plans to win the treasure. In the scene of multi-person dialogue, three screens can take turns to show the perspective of different characters, which makes the story more substantial and the expression more flexible. The above can be said to be the exclusive resources of ScreenX Hall, which can’t be seen on the single screen of other halls.

　 Jin Shiquan revealed to Zi Shijun that most of the ScreenX visual effects in day trader need to be realized through later transformation. If the production of ScreenX can be taken into account in the shooting stage in the future, the sense of immersion will be greatly enhanced.

　 In addition, Jin Shiquan believes that ScreenX has no specific type requirements or preferences in film selection. "People may think that ScreenX gives priority to blockbusters or action movies, but this is only one aspect. ScreenX is actually more interested in the integration with the scene, hoping to have more emotional integration, and will give priority to such films or clips, "Jin Shiquan said.

The amusement park thriller "Escape from the Chamber of Secrets" surprises "Dragon Master 3" slowly opens around the world.

Recommended star rating for Escape from the Chamber of Secrets: ★★★★

Last week, the only new film that made the top 12 list was the opening-year horror film Escape from the Chamber of Secrets from Sony Pictures. Last weekend, it earned 18 million US dollars in 2,717 theaters in North America, and the film cost was only 9 million US dollars. Escape from the Chamber of Secrets is the work of the new director Adam Robitel. His earlier directorial works include Hidden 4: Death.

The film is regarded as a distorted version of Saw for children, and it is estimated that the final North American box office of the film will sprint 45 million dollars. However, in two weeks, M Knight Shamalan’s new work Mr. Glass (the sequel to Split) will be released, which is expected to have a strong impact on Escape from the Chamber of Secrets.

At present, the cinema score of the film is B, IMDb score is 6.4, MTC49 score is 49, and the freshness of rotten tomatoes is 53%. The Los Angeles Times said: "Most of the films are very pleasant, but the logic is very bad, so it only needs you to enjoy the present and don’t think too much about it." The San Francisco Chronicle has a similar view: "Escape from the Chamber of Secrets is an amusement park. You have no reason to ask for more, and it has not done more — — For example, it sublimates a type of flow. But we must know that people like playgrounds for no reason. " The film will also be opened in mainland China on January 18th.

Another new North American film worth mentioning is Universal Pictures’ Dragon Trainer 3, which started painting in Australia and New Zealand last week, earning $4.7 million and $500,000 respectively, and will be painted in Indonesia, Norway and Lebanon next week. The release date of the film in North America will be February 22. The first two How to Train Your Dragon series grossed $217 million and $177 million respectively in North America.

Old film: Neptune has a global box office of 940 million, and the stamina of Happy Man 2 is gradually showing.

Disney’s "Happy Man 2" continued to earn $15.77 million last week, and the local box office reached $138.7 million in 19 days. The trend is very optimistic.
