Just want to hold the air conditioner Please remember these cold knowledge

  Improper use of air conditioningIn view of the actual needs of society, Puremind Industrial Chillers We need to change some original problems to better serve the society and benefit people. https://puremind.com/puremind-hot-sale/

  

  Not only will it increase electricity consumption,

  

  It may even affect your health.

  

  Today, follow the Shanghai Health Promotion Center.

  

  Let’s learn the “cold knowledge” of air conditioning use ~

  

  Don’t “open and close for a while”

  

  I wonder if you have had such an experience?

  

  Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.

  

  In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.

  

  Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.

  

  Pay attention to “humidity” and “temperature”

  

  The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.

  

  If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.

  

  Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.

  

  Don’t sweat and rush into the air-conditioned room.

  

  In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.

  

  For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.

  

  The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.

  

  Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.

  

  Do a good job cleaning

  

  The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”

  

  Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.

  

  The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.

  

  In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.

Iran releases its first helicopter accident investigation report_ No bullet marks found

in fact cnc milling services Our related products were once praised by users, which is the best self-affirmation of the products. https://www.ultirapid.com/services/cnc-machining/

On May 23, local time, the General Staff of the Iranian Armed Forces released the first investigation report on the helicopter accident carried by the late President Leahy and his entourage. It is reported that a professional technical team dispatched from Tehran arrived at the helicopter crash site at 9 a.m. local time on the 20th to collect information.

The report shows:

The helicopter flew according to the planned route and did not leave the designated route.

About a minute and a half before the helicopter accident, the pilot of the helicopter that crashed communicated with the other two helicopters of the flight crew.

No bullet marks or similar conditions were found in the remaining parts of the crashed helicopter.

The crashed helicopter caught fire after reaching high altitude.

Due to complex regional conditions, heavy fog and low temperatures, the search and rescue operation was extended and continued throughout the night. At 5 a.m. on May 20, with the help of Iranian drones, the location of the accident was accurately located.

No suspicious circumstances were found in the tower’s conversations with the crew.

The report also mentioned that most of the information related to the helicopter accident has been collected, and that some content needs more time for Iran to review. (General reporter Li Shuangxi)

Where is the most correct place for air conditioning Many people don’t know the secre

  Whether in cold winter or hot summer, air conditioning is an essential household appliance in our home, especially now that people’s living standards have improved, air conditioning has entered thousands of households. Many owners think that choosing air conditioning is the most important thing. I don’t know if it is familiar, but the placement of air conditioning is even more difficult. If it is not in the right position, it will bring trouble to our lives. Many people don’t know the secret of air conditioning placement. Come and have a look with Xiaobian.To some extent, industrial water chiller Our development has surpassed many peer businesses, but it has never stopped moving forward. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  Where are the air conditioners placed?

  

  (1) How to place the air conditioner in the living room?

  

  1. Air-conditioning is a kind of fast-running electrical appliance, so it will transfer the air flow from the outside to the home, such as the main disease in the southwest. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year. Correction method: use a small fan to change the wind direction opposite the air conditioner. In addition, if you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

  

  2. The most taboo of the air conditioner outlet is to blow to the financial position, and take away the wealth at home together with the cold wind, and the door at home is the main wealth. Therefore, if the air conditioner directly faces the door, it will not only drain the wealth, but also symbolize the popularity. It means that the home is not warm. Correction method: hang a glass screen or cloth curtain at the entrance to solve it.

  

  3. The air outlet of the air conditioner directly blows the main chair in the living room (that is, the sofa where three people sit), so that the face sitting here is blown very uncomfortable, which means that the backer is unstable and affects the work and career fortune. Correction: Let the air outlet of the air conditioner come from the side, or move the position of the main sofa.

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  (2) How to place the air conditioner in the bedroom?

  

  1. Air-conditioning often emits a certain amount of heat during refrigeration, so it must be installed far away from other electrical appliances and avoid being installed in corners, which can make the air-conditioning dissipate heat as soon as possible, ensure that it is not damaged, and prolong its service life.

  

  2. The air conditioner is installed at a certain distance from the bed. If it is facing the bed or too close to the bed, it will easily lead to the user catching a cold or catching a cold, which will adversely affect people’s health. Therefore, everyone needs to pay special attention to this when installing the air conditioner.

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  3. Air conditioning is installed in the bedroom in the northeast direction, because the radiation in this direction will be relatively small, so that the harm to the human body can be reduced to. In real life, many owners will ignore this problem, which is actually a very serious misunderstanding.

  

  4. The height of the air conditioner installed in the bedroom is very elegant. It is not appropriate to be too high or too low. It is recommended that it be higher than one meter and lower than two meters. This height is the most suitable, and its use effect will be in a new state, and it is more convenient for daily use.

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  What are the precautions for air conditioning placement?

  

  1, kitchen air conditioning moving stove fire

  

  It is the place where the whole family can fill their stomachs without installing a kitchen stove. If the air conditioner directly touches the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the occupants. In addition, the stove fire is also representative, so it has a great influence on the couple’s sexual life. Try not to install air conditioning in the kitchen, but if you must, try to blow the wind towards the ceiling or sideways.

  

  2, the dining room air conditioning dirty food

  

  Blowing the dining table directly is a big no-no, it will inevitably accumulate dust if the air conditioner blows the dining table directly, so it is very likely that the dust will fall into the hot food with the wind, and of course it is easier to cool the delicious meals on the table. Theoretically speaking, eating “dirty rice and cold dishes” for a long time will lead to the hidden worry of being defeated, so the air conditioner in the dining room should not be above or near the dining table.

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  3, bedroom air conditioning to prevent discomfort

  

  When people who use the air conditioner evenly to eliminate evil spirits sleep, the pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly on the human body, it will not only make the body uncomfortable and catch a cold, but also attract evil spirits more easily. Therefore, the air outlet will be raised upwards, or the windows in the room will be slightly opened to even the cold air coming straight.

  

  4. Air conditioning in the study transports energy

  

  Wenchang’s good luck comes to the air conditioner to make people cool, so it has the function of condensing thinking and improving reading concentration. If the air conditioner in the study can be moved to the north and the energy of air conditioning operation can be used, it will drive Wenchang’s good luck and be beneficial to candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

  

  Xiaobian will introduce the relevant information about the placement of air conditioners here for everyone. The placement of air conditioners directly affects our daily life and fortune. If you are also worried about the placement of air conditioners, you may wish to refer to the suggestions in the article and choose the optimal scheme, so as to feel the comfort brought by air conditioners to a certain extent without affecting human health. I hope that the knowledge summarized by Xiaobian can bring you help.

The report mentioned that Pamfilova also said that since the beginning of the presidential election campaign, more than 12 million cyber attacks have been recorded, 150 times the usual number. (Compiled by Li Ran)

Air conditioning knowledge energy-saving measures of central air conditioning

  Central air conditioning is an indispensable energy consumption operation system in modern buildings. Central air conditioning system not only provides people with comfortable living and working environment, but also consumes a lot of energy. According to statistics, the energy consumption of buildings in China accounts for about 30% of the total energy consumption. In buildings with central air conditioning, the energy consumption of central air conditioning accounts for about 70% of the total energy consumption, and it is increasing year by year. Therefore, how to efficiently use the energy and energy saving of central air conditioning system has become an urgent problem to be solved.So, Marine Air Conditioner 220V On the contrary, there is still a lot of room to play. https://puremind.com/product-category/puremind-air-conditioner/marine-air-conditioner/

  

  The normal operation of the central air conditioning system, its energy consumption mainly has two aspects [1″ target=_blank>: on the one hand, it is the energy consumption of cold and heat sources to supply air handling equipment with cold and heat; On the other hand, in order to transport air and water, fans and pumps need energy to overcome the flow resistance. The energy consumption of central air conditioning system is affected by many factors, and many operation links have energy-saving measures. Therefore, energy-saving of central air conditioning is a comprehensive project. The following introduces several commonly used energy-saving measures in terms of energy consumption of cold and heat sources and power consumption.

  

  1. Energy-saving measures for cold and heat sources

  

  1.1 Temperature and humidity control

  

  From the air treatment process of central air conditioning system, it can be seen that the lower the indoor temperature and relative humidity in summer, the greater the energy consumption of system equipment; The higher the indoor temperature and relative humidity in winter, the greater the energy consumption of the system equipment, and the corresponding initial investment and operating costs also increase.

  

  Because everyone’s requirements for comfort are very different, there can be a wider comfort zone for civil central air conditioning. In this comfort zone, when cooling in summer, take a higher temperature and humidity value; When heating in winter, a certain energy-saving effect can be obtained by taking a lower temperature and humidity value. The change of temperature and humidity in the building is closely related to building energy saving. According to empirical statistics, if the set temperature is lowered by 1≧ in summer, the energy consumption will increase by 9%. If the set temperature is raised by 1≧ in winter, the energy consumption will increase by 12%. Therefore, it is an effective measure to control the temperature and humidity in the building within the precision range of the set value.

  

  In order to reduce energy consumption, the indoor temperature and humidity base of air-conditioned rooms should be raised as much as possible in summer and lowered as much as possible in winter under the condition of meeting production needs and human health. At present, some owners blindly pursue the realm of “cold enough” and greatly improve the design standard of indoor temperature and humidity, which not only wastes a lot of energy unnecessarily, but also produces the negative effect of comfort.

  

  The higher the temperature and humidity control precision of air conditioning system, the better the comfort and the more obvious the energy-saving effect. The accuracy of the signal measured by the front end of the air conditioning system directly affects the precise control degree of the central air conditioning system. Therefore, the measured signals, especially analog signals such as temperature and humidity, must be as accurate as possible.

  

  Also, BAS with high control accuracy must be selected to control the central air conditioner. Because BAS uses DDC (Direct Digital Controller) to directly control the opening of electric water valve without intermediate regulator; In addition, DDC contains a wealth of calculation and control software, such as PID algorithm, fuzzy control algorithm, genetic algorithm and so on, to ensure the control accuracy.

  

  1.2 cold source efficiency control

  

  The performance index to evaluate the refrigeration efficiency of cold source is COP (Coefficient Of Performance). Refrigeration coefficient refers to the amount of cold energy that can be obtained per unit power consumption. The refrigeration coefficient has nothing to do with the nature of refrigerant, but only depends on the temperature T0 of the cooled object and the coolant temperature Tk. The higher T0, the lower Tk and the higher the refrigeration coefficient. So don’t make the chilled water temperature too low and the cooling water temperature too high during the actual operation of the air conditioning system, otherwise the refrigeration coefficient will be low, which will consume a lot of work and high power consumption to produce unit cooling capacity, and increase the energy consumption of the building. The following measures can be taken to improve the efficiency of cold source:

  

  1) reduce the cooling water temperature

  

  The lower the cooling water temperature, the higher the refrigeration coefficient of the cooler. For every 1≧ increase in the supply temperature of cooling water, the COP of the chiller decreases by nearly 4%. To reduce the temperature of cooling water, it is necessary to strengthen the operation management of cooling tower. First of all, for the cooling tower that stops running, the valves in and out of the water pipes should be closed. Otherwise, because the water temperature from the stopped cooling tower is high, the temperature of the mixed cooling water will increase and the refrigeration coefficient of the cooler will decrease. Secondly, after the cooling tower is used for a period of time, it should be overhauled in time, otherwise the efficiency of the cooling tower will decrease and the cooling water cannot be fully cooled.

  

  2) increase the temperature of chilled water.

  

  The higher the temperature of chilled water, the higher the refrigeration efficiency of the chiller. When the temperature of chilled water supply is increased by 1≧, the refrigeration coefficient of the chiller can be increased by 3%, so don’t blindly reduce the temperature of chilled water in daily operation. First of all, don’t set the set temperature of chilled water of the cold machine too low. Secondly, the water valve of the stopped chiller must be closed to prevent some chilled water from taking the bypass pipeline, otherwise, the amount of water passing through the running chiller will be reduced, resulting in the temperature of chilled water being lowered to a too low level by the chiller.

  

  2. Energy-saving measures for power consumption

  

  2.1 Transportation energy consumption control

  

  Power consumption mainly refers to the electric energy consumed by fans and pumps in system operation. Calculation formula of input power from fan and water pump:

  

  (1) (W): input power; : volume flow; : indenter; Eta: efficiency

  

  From Formula (1), it can be seen that reducing power consumption can be considered from the following three aspects: reducing flow, reducing system resistance and improving the efficiency of fans and pumps. The following measures can be adopted in engineering practice:

  

  1) adopt large temperature difference.

  

  If the temperature difference between the supply and return water (or the return air) used to transport cold and hot water (or air) in the system is large, then when the ratio between it and the original temperature difference is m, it is known from the flow calculation formula that the flow rate is reduced to 1/m3 when the large temperature difference is used. At this time, the power required by the water pump or fan will be reduced to 1/m3. It can be seen that the energy-saving effect of increasing the temperature difference is obvious.

  

  On the premise of meeting the requirements of central air conditioning accuracy, personnel comfort and technology, the temperature difference of air supply should be increased as much as possible. It should be noted that the temperature difference between supply and return water should not be greater than 8≧.

  

  2) choose low flow rate.

  

  Because the power consumption required by pumps and fans is roughly proportional to the flow velocity in the pipeline system, in order to achieve energy-saving operation effect, high flow velocity should not be adopted in design and operation. In addition, the low flow rate in the main pipe is also beneficial to the stability of the hydraulic condition of the system. For example, changing the rotational speed of the fan can change the performance parameters of the fan. The power of the fan has a cubic relationship with the rotational speed, while the flow rate has a linear relationship with the rotational speed. Lowering the rotational speed can greatly reduce the energy consumption while reducing the flow rate. When the flow rate is reduced by 1/3, the energy consumption can be reduced by about 70.4%, and when the flow rate is reduced by 1/2, the energy consumption can be reduced by about 87.5%, and the efficiency of the fan is basically unchanged, and it can still work stably and efficiently.

  

  3) adopt energy-carrying medium with high conveying efficiency.

  

  Under normal circumstances, the energy consumption of transporting cold and heat energy with water is less than that with air, and the diameter of water pipes used to transport the same cold and heat energy is much smaller than that of air pipes, which occupies a much smaller building space. This is also one of the main reasons for the rapid development of central air conditioning in recent years.

  

  Therefore, for the centralized refrigeration mode, in principle, the chilled water prepared by the equipment in the computer room should be transported as far as possible to the vicinity or use point of each central air-conditioning partition, and the air should be treated by the terminal non-independent central air-conditioning units (such as cabinet air-conditioning units and fan coils) for local use or for use in nearby rooms.

  

  2.2 VAV system control

  

  VAV system is an energy-saving countermeasure against the shortcomings of power consumption in air supply system. VAV system can be divided into two types: one is AHU!VAV system of air conditioner; One is the indoor fan variable air volume system (FCU-VAV system) in FCU system. AHU-VAV system is to fix the air supply temperature in the whole air duct system and adjust the air supply volume of the blower to cope with the change of indoor air conditioning load. In FCU-VAV system, the cold water supply is fixed, and the indoor FCU is equipped with a stepless power controller to change the air supply, that is, to change the heat exchange rate of FCU to adjust the indoor load change. These two methods can reduce the power consumption of the blower by adjusting the air volume, and at the same time, they can also increase the operating efficiency of the heat source machine and save the power consumption of the heat source, so they can achieve energy-saving effects in both air supply and heat source.

  

  The cooling capacity sent into the room can be determined by the following formula:

  

  2

  

  Where: c is the specific heat capacity of air, kj/(kg≧); ρ is the air density, Kg/m3; L is the air supply volume, m3/S; Tn is the indoor temperature,≧; Ts is the supply air temperature,≧; Q is the heat absorbed (or put) into the room, KW.

  

  If the air supply temperature is set as a constant and the air supply volume L is changed, different Q values can be obtained to keep the room temperature unchanged. Variable air volume control can adopt an air supply device that automatically adjusts the air supply volume according to the change of indoor load. When the indoor load decreases, it can keep the air supply parameters unchanged (no need to reheat) and keep the indoor temperature stable by automatically reducing the air volume. In this way, it can not only save the reheat required by the constant air volume system to increase the air supply temperature, but also reduce the power consumption of the fan and the cooling capacity of the refrigerator due to the reduction of the treated air volume. According to various data, VAV can save energy by 30% ~ 50% compared with constant air volume.

  

  2.3 Frequency conversion control

  

  In most buildings, the central air conditioning is at the maximum load only for a few days in a year. The cooling load of central air conditioning is always changing dynamically, such as the changes of various factors such as morning and evening, climate, passenger flow and activity content, which affect the cooling load of central air conditioning in real time. Generally, the cooling load fluctuates in the range of 5 ~ 60%, and most buildings are at least 70% in this situation every year. However, most central air conditioners are driven by maximum cooling load and maximum power due to system design. In this way, the contradiction between the actual cooling load and the maximum power output is caused, resulting in a huge waste of energy. This contradiction can be solved by adopting frequency conversion control.

  

  1) Fan and water pump frequency conversion control

  

  In the past, the AC motor itself didn’t adjust the speed, so the central air conditioning system had to rely on baffles and valves to adjust the air and water flow, and a lot of electric energy was wasted on baffles and valves. If the fan water pump is regulated by frequency conversion, the energy wasted on baffles and valves will be saved, and the average energy saving effect of each pump will be considerable.

  

  For the fan water pump, according to the principle of fluid mechanics, the parameters under similar working conditions have the following relationship [2″ target=_blank>:

  

  3

  

  Where Q1, H1, n1 and N1 are the flow, lift, power and rotation speed before the rotation speed change, respectively;

  

  Q2, H2, n2, N2: the flow, lift, power, and rotation speed after the rotation speed is changed respectively.

  

  According to Formula (3), the flow rate is proportional to the rotational speed, the pressure is proportional to the square of the rotational speed, and the power consumed is proportional to the cubic power of the rotational speed. For variable frequency speed regulation, the speed n is basically proportional to the power frequency f, when the power frequency f decreases, the motor speed also decreases, and the required power decreases rapidly with the cubic power of the speed, which shows that the energy-saving effect is very remarkable. Take the fan as an example, if the required air volume is 80% of the rated air volume, the speed will also drop to 80% of the rated speed, and the shaft power will drop by 51.2%; When the required air volume is 50% of the rated air volume, the shaft power drops by 12.5%. This power saving effect is also very impressive. It has been proved that the frequency conversion control of fans and pumps can save energy by 40% ~ 50%.

  

  2) Frequency conversion control of water chillers

  

  Because the compressor does not rule out the possibility of long-term operation under full load, the capacity of the motor can only be determined according to the maximum demand, so the design margin is generally large. In actual operation, the proportion of light load operation time is very high. Frequency conversion control is adopted to adjust the speed of compressor, so as to control the refrigeration capacity and keep the refrigeration unit in the best (most reasonable) operation state. Frequency conversion control improves the efficiency of air conditioner and the operation effect of refrigeration unit, thus realizing energy saving.

  

  The principle of variable frequency compressor is to adjust the displacement of compressor per unit time by adjusting the speed of compressor, so as to achieve the purpose of adjusting the refrigeration capacity. The mathematical relationship between refrigeration capacity and compressor frequency is as follows:

  

  4

  

  Where n is the rotational speed, f is the frequency of the motor, p is the polar logarithm of the motor, s is the slip of the motor, λ is the leakage coefficient, Ps is the suction pressure, vh is the suction volume, ni is the polytropic index, εi is the pressure ratio (exhaust/suction), δ0 is the relative pressure loss coefficient, and Zs and Zd are the actual gas compressibility coefficients, which are the average energy efficiency ratio.

  

  According to Formula (4), the refrigeration capacity is directly proportional to the frequency, so the refrigeration capacity can be controlled by frequency conversion regulation, thus achieving the energy-saving effect.

  

  Some adjustment methods (such as adjusting the valve opening and changing the blade angle) can not reduce the operating efficiency of the motor even if the demand is small. After adopting frequency conversion speed regulation, when the demand is small, the speed of motor can be reduced and the running power of motor can be reduced, thus further realizing energy saving. It has been proved that the frequency conversion control of water chillers can save energy by 20% ~ 30%.

South Korea does not plan to compromise on doctors _strike_ South Korean government is ready to fight to the end

know cnc milling services Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://www.ultirapid.com/services/cnc-machining/

The medical profession in South Korea has been playing a game with the government for more than half a month, the general election is just around the corner, and the doctors’ strike is escalating.

According to Yonhap news agency quoted by the Global Times, 430 professors from Seoul University School of Medicine attended the meeting on the 11th to issue an ultimatum: if the government does not come up with a sincere and reasonable solution to the situation of interns and residents’ collective resignation, all professors will submit their resignations on the 18th. South Korean media commented that the medical front line is likely to fall into greater chaos.

The South Korean government does not intend to compromise, and responded on the 12th, expressing serious concern about this. South Korean President Yoon Yue issued a directive on the 12th, calling for the rapid promotion of health care reform measures, including expanding the enrollment of medical schools, in accordance with the principles.

In addition, the South Korean government has sent license revocation notices to nearly 5000 doctors who refused to return to work, and decided to send 20 military medical officers and 138public health doctors to 20 hospitals from the same day to meet their urgent needs.

With the intensification of aging, the demand for medical resources in Korean society is increasing day by day. The South Korean government announced plans to expand the enrollment of medical students in early February: the enrollment of medical schools in colleges and universities increased from 3058 at this stage to 5058 in the 2025 academic year. According to South Korean health authorities, if the current enrollment scale remains unchanged, there will be a shortfall of 150000 South Korean doctors by 2035.

But the plan to expand enrollment has drawn strong opposition from doctors’ groups and medical students. They believe that the move will lead to excessive health care, strain the funding of the health care system, and lead to a decline in the quality of medical education. Moreover, South Korea lacks the mechanism to regulate the choice of departments for medical graduates, and blindly increases the number of medical students, which will lead to the accumulation of medical resources in big cities. Some medical staff are also worried that the plan to expand enrollment will lead to a reduction in the income of doctors.

Recently, medical professors at a number of South Korean universities are planning to resign collectively. On the 7th of this month, the Emergency response Committee of the Association of professors of Ulsan University Medical College agreed that the professor would submit his resignation on his own. The Association of Professors of Yonsei University School of Medicine set up an emergency response committee on the 12th, and the Association of professors of Cheng Junkuan University School of Medicine held a meeting on the same day. The School of Medicine of Katuli University will meet this week to discuss whether to take collective action.

In response to the possible collective resignation of medical professors, Oval Office officials insisted that since the president demanded rapid progress in accordance with principles, even professors were no exception for collective actions that left the front line of health care in violation of the Medical Law.

As of the 11th, the South Korean government has sent advance notice of administrative sanctions such as revocation of medical licenses to 5556 interns and residents who have left their posts.

Cao Guihong, head of South Korea’s Ministry of Health and Welfare, said at a meeting on the 12th that the decision of the professor’s collective resignation from the Medical College of Seoul University threatened the lives and health of patients, and that the government would do its utmost to maintain the emergency diagnosis and treatment response system and solve the problem of disorder in the medical scene. He called on professors to protect the lives of patients and work with the government to bring outgoing internships and residents back to the medical front line.

On the 12th, the faculty of Seoul University School of Medicine proposed a compromise. They held a press conference in the Korean National Assembly, saying that both the government and the Korean Physicians Association should abandon their inherent position and entrust overseas authorities and institutions recognized by all parties to analyze South Korea’s health and medical indexes. and according to the results of the analysis to decide whether to increase the number of medical school enrollment, at the same time to build a dialogue mechanism with the participation of the government, medical association, government and opposition, national representatives, professors, internships and residents. Formulate practical basic medical, community and public health policies in the coming year.

However, according to Yonhap news agency, an official from the South Korean President’s Office confirmed on the 12th that the plan to expand the enrollment of medical schools by 2000 students a year will not be adjusted. This figure is scientific, and the government’s determination to promote health care reform has not changed.

Less than a month before South Korea’s parliamentary election on April 10, South Korea’s ruling party has regained a lot of support for its policy of expanding enrollment in medical schools. The results of an opinion poll released by Gallup in South Korea on March 8 showed that the good rate of President Yoon Yue’s administration performance was 39%, and the bad rate was 54%. As for the reasons for praise, the answer to the expansion of medical school enrollment accounted for the largest proportion, accounting for 28%, followed by prompt decision, courage and perseverance (9%). According to an opinion poll released by the agency on February 23, Yin Yue’s good evaluation rate was 34%, and the poor evaluation rate was 58%.

For this protracted standoff, some Japanese media commented that the demand for reconciliation in South Korea is growing day by day. Doctors and the government should not be in the boxing ring. People’s patience is disappearing. We must find a way out of this quagmire through dialogue.

The youngest Russian presidential candidate just celebrated his 40th birthday

Therefore, this is the choice cnc turning service The reason, there is no denying its positive impact. https://www.ultirapid.com/services/cnc-machining/

At 8: 00 local time on March 15, official voting in the Russian presidential election kicked off in Russia’s easternmost Kamchatka peninsula. According to the plan, the large-scale voting campaign, which spans 11 time zones, will end at 8 pm on the 17th in the westernmost Kaliningrad region.

Compared with eight presidential candidates in 2018, the number of presidential candidates in 2024 has halved: in addition to the incumbent President Vladimir Putin, there are Slutsky of the Russian Liberal Democratic Party, Haritonov of the Communist Party of the Russian Federation and Novakov of the Russian New Party.

Among the four presidential candidates, two have participated in the general election, namely Putin, who participated in the general election four times, and Khalitonov, who participated in the 2004 general election. Slutsky and the youngest candidate, Novankov, both ran for the first time this year. Haritonov is 75 years old, while Davankov was born in 1984.

Newcomers in politics

Last month, da Vankov celebrated his 40th birthday. On the second day of his birthday, he went to Channel 1 in Russia to participate in the first round of televised debates in the presidential election.

In the first round of debate, representatives of D’avankov, Haritonov and Slutzky stood in the middle of the circular stage to discuss the national education system, teachers’ salaries and other election-related issues. Putin’s campaign headquarters had previously announced that the incumbent Russian president would not take part in any candidate debates this season.

The 75-year-old Haritonov stood on the far right, his gray hair in sharp contrast to his post-80s competitor Leonardo da Vankov. During the debate, D’avankov reinterpreted his campaign plans, including fighting for the freedom of businesses and people, opposing the blockade of social media and punishing users, and letting children choose to be educated in their hometown or in big cities. to be who you want to be. At the end of the debate, he ended with the campaign slogan of his party, and it was time to change to a newcomer.

Compared with Haritonov, who has been in politics for more than 30 years, D’avankov is an out-and-out newcomer in politics, and even his party is a new party.

In January 2020, Alexei Nechayev, a member of the all-Russian people’s Front and founder of cosmetics production F, announced that he would create a new political party with the goal of changing people’s lives. the ideas pursued include promoting the change of power, reducing bureaucracy, developing industrial and high-tech production, creating the best conditions for the development of small businesses, increasing employment opportunities and population income, and ensuring affordable housing for the people. In addition, the party also advocates freedom of speech and assembly and is regarded as the representative of liberal parties.

On March 1 of the same year, the founding meeting of the New Party was held. Alexei Nechayev was subsequently elected chairman of the party, and in the same year, D’avankov joined the New Party to coordinate the work of regional branches.

In the Russian State Duma election in September 2021, the New Party became a dark horse, winning 533% of the votes, successfully winning 13 seats and squeezing into the Russian Duma. At that time, some analysts pointed out that this represented the emergence of new political forces calling for change in Russia.

In October 2021, Davankov became Vice Chairman of the State Duma, responsible for overseeing health and culture-related issues.

Last summer, the New Party elected D’avankov to run for mayor of Moscow. At that time, he promised to go all out for the welfare of the capital.

During his campaign for mayor of Moscow, D’avankov showed a dynamic and friendly side: he jumped off the 10-meter platform with Russian men’s diving Olympic champion Ilya Zakharov; work with TV host Elena Letuchaya to clean up the garbage at the bottom of the Moscow river At the nomination event in Khoroshevsky Forest Park, he even personally prepared a barbecue for the participants. At that time, Russian media commented that da Vankov created the image of your government boyfriend.

As his first attempt to take part in the election, da Vankov finally lost to veteran Sergei Sobyanin. According to the results of the vote on September 10, 2023, the latter was re-elected for a third time with 76.39% of the vote, while Davankov ranked fourth with 534% of the vote.

Only three months later, D’avankov was jointly nominated by the New Party and the growth Party. This time, he will be running for the post of president of Russia.

The highest income

Da Vankov was born in Smolensk on the Dnieper River in western Russia. His father, Andrei da Vankov, was a pilot, and his grandfather, Vadim da Vankov, was a well-known chemist who participated in the research of artificial kidney materials. He has published more than 400 scientific papers and won many awards.

Instead of inheriting the business of his father and grandfather, D’avankov inherited the entrepreneurial spirit from his uncle Alexander Davankov. Alexander da Vankov and Alexei Nechayev co-founded cosmetics production F as early as the 1990s. Since 2006, it has been on the list of the largest cosmetics in the world.

According to media records, da Vankov has made money on his own since he was a teenager. He has washed cars and worked as a bartender. At the age of 14, he had a career of his own and started a computer club, which gave him his first taste of the fruits of entrepreneurship. While studying how to make money, Davankov also developed a strong interest in history. He was admitted to the history department of Moscow State University from his hometown and later received an associate doctorate in sociology from the Russian State Social University in 2008.

After moving to the capital, Davankov continued to work as a courier and real estate agent during his studies, so much so that people around him later described him as knowing how every penny was earned. Davankov is also an enterprising entrepreneur, from 2001 to 2021, he founded five large enterprises in finance, computer, small aviation and other fields.

In 2013, D’avankov began to manage F Cosmetics. Under his administration, the performance doubled in two and a half years, according to politicians.

Currently, Davankov has two: one is SA, registered in the Teville region, which organizes skydiving, and the other is Asia Credit, a microfinance institution registered in Moscow, which provides loans to citizens of Kyrgyzstan, Tajikistan and Uzbekistan. Mr Davankov has a 54 per cent stake, according to the information.

In philanthropy, Davankov also led the Russian Captain Education Program support Fund. The project aims to find young people with entrepreneurial spirit and help them build their own businesses. In 2018, Davankov became deputy director of the Russian Land of opportunity Project. The project was personally signed and approved by Putin and supervised by Sergei Kiriyenko, the first deputy director of the Russian president’s office at that time.

In January this year, Russia’s Central Election Commission released information on the income of Russian presidential candidates. Da Vankov, who earned 76.9 million rubles (5.6 million yuan) in the six years before the election, became the highest-paid candidate, about 10 million roubles higher than Putin. In addition, Davankov owns a house and a piece of land in the Moscow area, as well as a 1/4 share of an apartment in Moscow. He also owns a 2019 Mercedes-Benz Maybach and his wife Yulia Davankova owns a BMW.

The other two candidates, Haritonov and Slutsky, earned about half as much as Davankov over the same period.

Political training

Although he has been in power for less than five years, during his tenure in the State Duma, D’avankov was regarded as a young generation of politicians with good working ability, as well as the drafter and co-drafter of nearly 100 bills. including officials who prevent social users from bullying and insulting women’s feelings should be fined 100000 roubles, and schools should cancel homework.

Not only that, da Vankov, who has no one in the family involved in politics, is also trained to speak in public. He will refuse to criticize the current government and other political opponents in the election manual. No one will benefit from criticism, nor did I do so during my campaign for mayor of Moscow. He pointed out that he would focus on his party’s agenda, that is, what people are most concerned about, going to cities to talk to people and telling people that the New Party would lead Russia to development rather than technological backwardness and degradation.

Before the election, two Russian anti-war candidates, Deng Zova and Najieridin, were disqualified from the election. When talking about the conflict between Russia and Ukraine, Davankov was also very cautious. Instead of publicly opposing it, he called it a tragedy. ‘very few people I know can directly say that war is great,’he said in an interview with Xenia Sobchak last year. He believes that war will never bring universal happiness.

In February, when the Russian State Duma faced urgent ratification of the friendship and cooperation treaties with Luhansk and Donetsk, the New Party voted in favor. Mr Davankov then succinctly expressed the change in the party’s position: the president made the right decision. We discussed and debated until a democratic decision was made. Once a decision has been made, action is needed. After the full escalation of the crisis in Ukraine, Davankov has also been on the sanctions list of the European Union, Britain, the United States and Canada.

For Davankov, participating in the presidential election is a kind of political training. Russian political scholar Sergei Markolov said in an interview with the media. Markolov believes that although D’avankov won some public support in Moscow’s mayoral election, he is not a politician.

According to Sergei Markolov’s prediction, D’avankov will not get many votes. The problem is not that people may not understand the politician’s position, but that few people outside Moscow and St. Petersburg know about the existence of such a candidate.

According to the latest poll data from the all-Russian Public opinion Research Center (VTIOM) on March 3, 6% of voters plan to vote for him, ranking second only to Putin’s 75%. In a January poll, only 1% of voters expressed support for the newcomer.

As for his own attitude, in December last year, when he was announced as the youngest candidate in the 2024 general election, a reporter asked him whether he planned to win the election. He replied with a smile: it depends on what people think is victory (reporter Zheng Liying)

  Where are the air conditioners placed?

  

  (1) How to place the air conditioner in the living room?

  

  1. Air-conditioning is a kind of fast-running electrical appliance, so it will transfer the air flow from the outside to the home, such as the main disease in the southwest. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year. Correction method: use a small fan to change the wind direction opposite the air conditioner. In addition, if you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

  

  2. The most taboo of the air conditioner outlet is to blow to the financial position, and take away the wealth at home together with the cold wind, and the door at home is the main wealth. Therefore, if the air conditioner directly faces the door, it will not only drain the wealth, but also symbolize the popularity. It means that the home is not warm. Correction method: hang a glass screen or cloth curtain at the entrance to solve it.

  

  3. The air outlet of the air conditioner directly blows the main chair in the living room (that is, the sofa where three people sit), so that the face sitting here is blown very uncomfortable, which means that the backer is unstable and affects the work and career fortune. Correction: Let the air outlet of the air conditioner come from the side, or move the position of the main sofa.

  (2) How to place the air conditioner in the bedroom?

  

  1. Air-conditioning often emits a certain amount of heat during refrigeration, so it must be installed far away from other electrical appliances and avoid being installed in corners, which can make the air-conditioning dissipate heat as soon as possible, ensure that it is not damaged, and prolong its service life.

  

  2. The air conditioner is installed at a certain distance from the bed. If it is facing the bed or too close to the bed, it will easily lead to the user catching a cold or catching a cold, which will adversely affect people’s health. Therefore, everyone needs to pay special attention to this when installing the air conditioner.

  3. Air conditioning is installed in the bedroom in the northeast direction, because the radiation in this direction will be relatively small, so that the harm to the human body can be reduced to. In real life, many owners will ignore this problem, which is actually a very serious misunderstanding.

  

  4. The height of the air conditioner installed in the bedroom is very elegant. It is not appropriate to be too high or too low. It is recommended that it be higher than one meter and lower than two meters. This height is the most suitable, and its use effect will be in a new state, and it is more convenient for daily use.

  What are the precautions for air conditioning placement?

  

  1, kitchen air conditioning moving stove fire

  

  It is the place where the whole family can fill their stomachs without installing a kitchen stove. If the air conditioner directly touches the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the occupants. In addition, the stove fire is also representative, so it has a great influence on the couple’s sexual life. Try not to install air conditioning in the kitchen, but if you must, try to blow the wind towards the ceiling or sideways.

  

  2, the dining room air conditioning dirty food

  

  Blowing the dining table directly is a big no-no, it will inevitably accumulate dust if the air conditioner blows the dining table directly, so it is very likely that the dust will fall into the hot food with the wind, and of course it is easier to cool the delicious meals on the table. Theoretically speaking, eating “dirty rice and cold dishes” for a long time will lead to the hidden worry of being defeated, so the air conditioner in the dining room should not be above or near the dining table.

  

  Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!

  

  3, bedroom air conditioning to prevent discomfort

  

  When people who use the air conditioner evenly to eliminate evil spirits sleep, the pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly on the human body, it will not only make the body uncomfortable and catch a cold, but also attract evil spirits more easily. Therefore, the air outlet will be raised upwards, or the windows in the room will be slightly opened to even the cold air coming straight.

  

  4. Air conditioning in the study transports energy

  

  Wenchang’s good luck comes to the air conditioner to make people cool, so it has the function of condensing thinking and improving reading concentration. If the air conditioner in the study can be moved to the north and the energy of air conditioning operation can be used, it will drive Wenchang’s good luck and be beneficial to candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

  

  Xiaobian will introduce the relevant information about the placement of air conditioners here for everyone. The placement of air conditioners directly affects our daily life and fortune. If you are also worried about the placement of air conditioners, you may wish to refer to the suggestions in the article and choose the optimal scheme, so as to feel the comfort brought by air conditioners to a certain extent without affecting human health. I hope that the knowledge summarized by Xiaobian can bring you help.

Geneva, March 14: Ambassador Chen Xu, Permanent Representative of China to the United Nations Office at Geneva and other international organizations in Switzerland, delivered a joint speech on behalf of 80 countries at the 55th session of the United Nations Human Rights Council on the 14th on artificial intelligence to promote children’s rights.

Joint speeches pointed out that artificial intelligence is the name of a new field of human development, and should adhere to the concept of extensive consultation, joint contribution and sharing, and work together to promote artificial intelligence governance. Children are the future and hope of mankind. The new generation of children has become one of the main groups using artificial intelligence technology and enjoying artificial intelligence.

Joint speakers emphasized that children’s mental health issues are crucial. The joint speech called for promoting the high-quality development of artificial intelligence, helping to promote children’s mental health, and protecting children’s rights.

They spoke together and put forward three propositions. The first is to adhere to child-oriented principles, uphold artificial intelligence for children, and give full play to the important role of artificial intelligence in guiding children’s mental health. The second is to adhere to fairness and universal benefits, strengthen exchanges and cooperation, provide technical support, share experiences and good practices to developing countries, and bridge the smart divide. The third is to adhere to harmony without difference, respect the sovereignty, laws, national conditions and historical, religious and cultural backgrounds of each country, and strengthen international artificial intelligence governance on this premise.

This is one of a series of speeches initiated by China at the Human Rights Council on artificial intelligence to promote the rights of specific groups, and has received widespread support and praise from Member States of the United Nations. China once launched a joint speech on artificial intelligence to promote the rights of people with disabilities at the 53rd session of the Human Rights Council.
