According to scientists, the reason farming has to use Neonicotinoids is to combat the many predators that are ready to pounce on corn or soybean seeds, every time they are sown in the ground. Seeds are impregnated with drugs before sowing. Photo: Scientific Beekeeping What are neonicotinoids? Neonicotinoid has been banned for use in Australia and Europe since 2013. This is a pesticide derived from nicotine (the addictive substance found in tobacco), the way to use is to dissolve in water and spray on plants. for the plants to absorb themselves, forming an artificial “immune system” to protect the crops. Neoincotinoids are thought to be effective against pests and insects, but are safe for mammals. However, because of its strong effect on insects, it also affects bees directly, reducing the number of pollinators. This pesticide is said to reduce the sperm count of male bees by up to 40%, as well as reduce their lifespan from an average of 22 days to 15 days, thus reducing the chances of male bees fertilizing the queen bee. also decreased. Besides disease, soil-dwelling pests such as helminths and larvae can also damage seeds and seedlings, along with terrestrial insects such as bean leaf beetles and aphids. seeds and saplings. Therefore, in the field of seed treatment against insects and diseases, farmers often treat seeds in combination with fungicides (IST) to help plants sprout straight and grow early. It is easy to mention some of the popular Neonicotinoid IST methods such as Imidacloprid (Gaucho, Bayer Crop Science), Clothianidin (Poncho, BASF) and Thiamethoxam (Cruiser, Syngenta)… Seth Naeve, an agronomist specializing in soybean research at the University of Minnesota Extension (USA), said that Neonicotinoid insecticides are highly water-soluble, helping to activate protection from insects. Great early season. Shawn Potter, Syngenta’s head of seed care product marketing, said that the growth of the seeds after treatment was driven in part by previous seasons. “Early seeding from a wet, cool, or both, seeds and seedlings will be exposed to various diseases. “Without seed treatment, crops could be damaged early on,” said Mr Potter. Nick Tinsley, BASF technical specialist, added: “Farmers and retailers alike can easily treat corn and soybean seeds with Neonicotinoid insecticides as well as fungicides from the company. producers to protect crops”. For decades, seed companies have treated corn with fungicides. However, IST only started to be added to the fungicide seed treatment of soybeans in the early 2000s. Studies have demonstrated that a combination of seed treatment with both fungicides and insecticides increases soybean yield per acre by 2 bushels (equivalent to 72.74 kg/0.4 ha). According to Mr. Potter, in general, each “shift” of treating soybean pest/mushroom combos will cost from 10 to 12 USD per seed unit (ranging from 80,000 to 140,000 seeds/0.4 ha). That’s because 70% of treatment costs go to pesticides, while the profit-taking rate per acre is between $16 and $17. This assumes that soybeans cost $12 per bushel and that the cost of the pesticide seed treatment is between $7 and $7.50 per seed unit. Entomologists in the Midwest and South America have also observed that the average soybean yield spike of 2 bushels per acre from this combination. “Some years are higher, some years are lower,” says Sebe Brown, an entomologist at the University of Louisiana. Responses tended to be higher in cases where soybeans were planted early, two crops, or planted after a cover crop.” Gus Lorenz, a scientist at the University of Arkansas, adds: “Companies have provided growers with insurance to maintain good standing. At current seed prices, the cost of treating seeds with pesticides is a good investment.” A synthesis of studies in a 2019 report representing agronomists and entomologists from 14 universities found that the best recorded soybean yield was an increase of 3.3 bushels per acre. after using the combined seed treatment solution. However, in some cases in Minnesota, the benefits are so small that it is argued that farmers should not be encouraged to use seed treatments or should apply them selectively. Concerns Previously, scientists believed that neonicotinoid pesticides were the main cause of the decline in bee populations and pollinators worldwide. A few years ago, the United Nations published alarming figures: In the first 10 years of the 21st century, the number of bees in the world has decreased by 85% in the Middle East, about 30% in the US and Europe. Neonicotinoids are likened to “birth control pills” for bees and reduce the population of bees. Photo: GCM Bees are the intermediate species that help pollinate more than 75% of the world’s food and fruit crops, so a decrease in the number of bees also means a reduced crop or even a crop failure. However, long-term studies by Syngenta suggest that the health effects of bees are negligible when using Neonicotinoid seed treatments to kill insects. According to Mr. Potter, what many experts agree on is that the health of bees depends on the interaction of factors such as parasites, disease, nutritional health and weather phenomena. A 2019 study published in the journal Scientific Reports detailed the effects that imidacloprid had on white-tailed deer. When imidacloprid (an insecticide that acts as an insect CNS toxin, belonging to the genus Neonicotinoids) was increased in the animal’s spleen, factors such as progeny viability, length of jawbone, body weight and visceral weight all decreased. Records show that at least 60% of white-tailed deer killed indicate the presence of Imidacloprid. According to expert Jonathan Lundgren, all insecticides can negatively impact mammals and bees. “The use of insecticides is so widespread these days that they are present in almost every growing system across the United States and are truly binding. These insecticides are affecting ecosystems in ways that we could not have foreseen.” Meanwhile, the companies that manufacture and trade in Neonicotinoid seed treatments have always denied this and asserted that “the products are safe if used according to the instructions on the label”. Compounds such as polymers coat the seeds or products like Bayer Fluency Agent Advanced to help prevent release into the environment, said Chip Graham, Bayer Crop Science’s North American director of seed development. “Initially we had really low dust levels, but these products ensure that pesticides remain on the seeds and reduce contamination levels during the growing process,” said Mr. What is the future of farming? Instead of treating seeds with neonicotinoid insecticides, Mr. Lundgren called for regenerative methods, such as tilling and changing seasons, increasing crop diversity as well as reducing pest pressure. bugs, insects. “Farmers need to understand that these seed treatments really don’t help them much,” said Lundgren. Neonicotinoid pesticides are believed to reduce bee pollinators, threatening food security. Photo: TN Meanwhile, expert Graham said that banning this seed treatment would be detrimental to farmers because “there are currently no foliar sprays to treat early-season insects as a rescue application”, so ” Seed treatment in this way is most effective to provide activity against early-season pests of maize and soybean.” Agronomist Naeve said: “They’re a good example of how the best tools we’ve ever had in agriculture, but it’s not a good idea to treat the entire soybean acreage. They can be a double-edged sword.”

Disadvantages of Japanese cars

1. Weak high-end brands

   This is an important reason why many Japanese cars are abandoned when changing cars. Compared with the German BBA, the domestic sales of Acura and Infiniti are bleak for Japanese luxury brands. Both the market share and the brand appeal are very weak. Lexus, the only relatively strong Japanese luxury brand, cannot be compared with the Germans in terms of sales and appeal. Therefore, when many people change cars, they want to switch to a luxury brand model because of income growth. Because there are not many models of Japanese luxury brands, they will naturally switch from Japanese to German.

   

2. Lack of driving pleasure

   Frankly speaking, not all Japanese models lack driving pleasure. Subaru and Mazda have many fun-driving models, but the problem is that almost all Japanese cars with driving pleasure are generally sold models, while Japanese cars sell well. Good models, such as Nissan and Toyota models, lack driving pleasure. The self-priming engine is paired with a CVT gearbox, which is smooth but lacks the sense of paragraph shifting. The chassis is more comfortable, but the handling is average. Generally speaking, Japanese cars are like boiled water, which is cheap to quench their thirst, but they always feel a little bit less tasteful. For young people, they are too weak. Therefore, when changing cars, many people want to change to another one. A car that is fun to drive.

3. The technology is conservative and lacks a sense of technology

   Perhaps because more stability is taken into account, Japanese cars are generally less enthusiastic about the use of new technologies. For example, for luxury brands like German, the interior design is more technological than one, and the car system is more dazzling. Cool, but many Lexus models don’t even have a Carplay. Turbocharging, dual clutch and other technologies, Japanese cars are also relatively conservative in application, which also makes many young people not interested in Japanese cars.

   

4. General exterior interior design

Most of the designs of Japanese models are not amazing. For example, Toyota models and Nissan models are less attractive than German models of the same level.

1. General interior materials

   Compared with American cars, domestic cars, and French cars, Japanese cars tend to be stingy in interior materials, with more hard plastics, and the interiors have a general sense of luxury.

   

Advantages of Japanese cars

1. Good fuel economy

   Many people say that Japanese cars are fuel-efficient but have poor safety. This is completely false. Today’s most fuel-efficient models are actually Volkswagen’s turbocharged and dual-clutch models, followed by Japanese cars. In addition, in terms of safety, except for Honda, other brands of Japanese cars are not inferior to the public in terms of safety.

2. Good comfort

   Japanese cars generally prefer comfort tuning, and they value the ride comfort of the second row. Whether it is the height of the platform protrusion, the tuning of the suspension and the powertrain, etc., they tend to give passengers a better riding experience.

3. Low failure rate

   Although only changing glass water for ten years is an exaggeration, whether you admit it or not, Japanese cars do have certain advantages in terms of quality stability due to the adoption of more stable and mature technologies, and lower failure rates bring lower later stages. The cost.

4. High value preservation rate

   The preservation rate of Japanese cars is the highest among all car lines, especially Toyota, Lexus, and Honda. This means that when selling cars, Japanese cars can be sold for tens of thousands of dollars.

   

   Therefore, Japanese cars are stable in quality, fuel-efficient, and comfortable, and are suitable for family cars. However, they lack driving pleasure and sense of technology, and high-end brands have weak appeal. Many people choose Japanese cars after their first car. When you change cars, you will abandon Japanese cars. In fact, when you buy a German car and change a car, many people choose Japanese cars. It is a normal behavior and there is no need to overinterpret it.

In the first 4 months of the year, Kia Seltos was the best-selling 5-seater SUV in Vietnam with cumulative sales of 5,158 units, far ahead of competitors in the same segment such as Toyota Corolla Cross (3,909 vehicles) Hyundai Kona (1,413 vehicles), Honda HR-V (574 cars) or Ford EcoSport (480 cars). According to a Kia salesperson in Hanoi, the main contribution to this result of Seltos Luxury is between the Deluxe and Premium models. This version is the most chosen by customers among the 3 variants of Kia Seltos being sold in Vietnam. The price is “just right for the piece” and the design is eye-catching Currently, Kia Seltos has a suggested selling price of VND 609-729 million, VND 10-20 million higher depending on the version compared to the launch time in July 2020. In which, the Luxury version is priced at 659 million VND and the cost of rolling in Hanoi is about 760 million VND. This price is considered to be quite competitive when compared to other models in the same segment. For example, the 1.8G base version of Corolla Cross is priced at 720 million VND, HR-V version G costs 786 million VND, Kona 2.0AT Standard costs 636 million VND or Peugeot 2008 costs 739-829 million VND. With a small amount of money, combined with an eye-catching design, Kia Seltos Luxury has received a lot of attention from young users, suitable for customers who buy a car for the first time for family use and do not require too much of a car. equipment and technology. Anh Quoc Khanh (HCMC) said that when he bought a car half a year ago, he wondered about the highest version of Seltos and EcoSport, several tens of millions of dong more expensive. Finally, consulting with relatives, he chose Seltos because of its larger, more superficial shape, and the cabin design is also more modern and spacious than the American SUV, suitable for families. In addition, Mr. Khanh said that the appearance of Seltos Luxury and Premium is almost identical, only slightly different in the first part, taking the middle version is more suitable for financial conditions, saving a considerable amount of money spent on car maintenance. Sufficient amenities Of course, Kia Seltos Luxury users will have to accept utility cuts compared to the Premium version. The most noticeable is the front light cluster instead of the Full-LED type, the Luxury version is only equipped with Halogen Projector lights and fog lights, the turn signals are also Halogen type. In return, other highlights of Seltos in general are still maintained on the Luxury version, which can be mentioned 17-inch alloy wheels, LED position lights, LED taillights, chrome trim in the grille and rear. sport spoiler, shark fin antenna… The overall dimensions of the Kia Seltos are also good in the segment, slightly better than EcoSport, Kona and equivalent to Corolla Cross, 2008. Specifically, the Seltos length x width x height parameters are 4,315 x 1,800 x 1,645mm respectively. , wheelbase at 2,610 mm and the best ground clearance in the segment – 190 mm. According to Mr. Khanh, the amenities of the Luxury version are sufficient for family needs. Leather seats, automatic air conditioning, still 6 speakers and Apple CarPlay connectivity, a slightly smaller screen (8 inches compared to 10.25 inches) is not a problem. The main plus point is that there are rear vents, many B-class or even C-class SUVs lack this detail. The main disadvantage compared to the Premium version belongs to the driver when there is no electric seat, no ventilation, no cruise control or automatic anti-glare interior rearview mirror. The rest, no interior lights or the removal of the sunroof is also a good point because these two equipment are not necessary. Outstanding operating parameters but still minor errors It is easy to see that the parameter set of Kia Seltos is somewhat outstanding and attractive when placed next to rivals as well as models in the price range of 600-700 million VND. The 1.4L turbocharged engine has a capacity of 138 horsepower and 242 Nm of torque, along with the option of 3 driving modes and 3 terrain modes. However, the Korean SUV is inherently only an urban car and front-wheel drive, these functions can only partially support when it is necessary to go on bad roads, but it is difficult to use it for offroad. A 7-speed dual-clutch automatic transmission is standard equipment to help improve turbo engine lag. However, with Vietnamese traffic conditions, when experiencing traffic jams or moving slowly, the Seltos gearbox may overheat and the gearbox overheating warning light will appear on the dashboard. This condition does not significantly affect the operation of the vehicle. Another problem that many Seltos often encounter is water leaking into the cabin when it rains. This error is reflected by users because the rubber gasket on the front door and chassis is not sealed, when it encounters water, it will leak. When this problem occurs, it will be received by the Kia dealer and fixed by shrinking the corrugated iron in the inner gasket of the door. Besides, because it is a hot car, the demand exceeds the supply, so Seltos often has a shortage of goods and buyers have to “line up” to receive the car. Exchange with Zing , a Kia sales team leader in Ho Chi Minh City said that if you make a deposit in mid-June, you will have to wait until the end of July to have a car, which means the waiting time is more than 1 month.

1. Oak flooring This is the hardwood commonly used for traditional flooring. The wood itself is durable, but the color can fade over time. For this reason, if you use oak flooring, you need to maintain it after a long time of use. 2. Mahogany flooring Classic and elegant mahogany ranks among the best hardwoods for flooring. It is both durable and water resistant. Besides, its bold colors are a great investment for a timeless design. But, all of those benefits definitely come with a hefty price tag, and this can be seen as a downside if you’re on a tight budget. 3. Lyptus wood floor Although lyptus is a less popular choice for hardwood floors, it offers a number of benefits to the room; like exotic appearance and durability. However, its quality and style are underestimated compared to some popular options like Teak or mahogany. 4. Ash wood floor Ash wood floors come in many different types and styles, so you have many options for designing your floor. In it, its colors and patterns have light light shades. This also means that you need more care and cleaning to keep your ash floors in good condition. 5. Hardwood floors Hardwood floors are your best bet when it comes to rustic design and also demanding timeless looks and durability. However, this type of wood is also quite hard and strong, making it more difficult to install. For this reason, the cost of installing pecan floors is often higher than that of other hardwood floors. 6. Pine wood floor Although classified as hardwoods, pine can be classified as softwood or solid wood. In addition to being cheap, pine also offers rich colors, especially this type of wood will fade over time. But also because of the soft wood characteristics, pine wood floors are often dented or easily scratched. 7. Cherry wood floor Cherry wood is less durable than most hardwood floors, so cherry wood floors are more susceptible to scratches. 8. Brazilian Cherry Wood Flooring Similar to all cherry wood species, Brazilian cherries are elegantly grained with a reddish or pinkish color. Although this wood is more durable than regular cherry wood, when it comes to flooring installation, you’ll still need expert help. 9. Walnut wood flooring Walnut is considered to be the best laminate flooring for any home. It is durable and never goes out of style. You can also find a wide range of walnut floor patterns, from simple light to exotic dark. The only problem with using walnut flooring is probably its high price which can affect your construction budget. 10. Rosewood flooring In general, rosewood is appreciated for its unique grain, wide color range and distinctive aroma. However, because this type of wood has properties that are more suitable for furniture than flooring, finding and installing this type of wood flooring will be quite difficult. 11. Maple flooring The delicate wood grain of maple makes it easy for homeowners to install floors in both small and large areas. Not only that, but maple is also highly durable, so it is one of the most chosen woods for installing hardwood floors. Even so, you will find it difficult to change the color of the hardwood floor. 12. Bamboo flooring Bamboo is a great choice for those who want to bring a natural, traditional atmosphere into the room. Once installed, bamboo floors can be sanded and refinished to retain quality over time. However, because of its soft and termite properties, this type of floor is not suitable for humid areas. 13. Douglas fir flooring Characterized by a blend of brown and orange, Douglas fir flooring gives the room a warm feeling. This wood also has a softer texture than other hardwoods so regular maintenance is required to reduce floor damage. 14. Teak . Wood Flooring Teak is suitable for almost any floor design, from traditional to modern. It has a natural shine and durability, but the luster that this wood provides will wear out over time. That’s why you need to oil your teak floor every few years to keep it shiny. 15. Birch wood floor Put birch on the top list if you’re looking for hardwood floors that are both stylish and functional. Even so, keep in mind that birch cannot be installed in an area with high humidity. 16. Ebony Flooring Ebony is harder and denser than other types of flooring. This provides great durability when you use it for flooring. Unfortunately, today ebony is quite rare because of massive logging. 17. Cork floor Cork flooring provides a pleasant surface to walk on due to its natural warmth. This is a high-quality wood that can resist fire and mold for a long time. Even so, cork is not a good choice for kitchen floors as it can be easily stained by oil or liquid spills. 18. Eucalyptus wood floor In addition to being affordable, eucalyptus flooring is easy to install and requires only a little maintenance. This type of flooring is also safe and resistant to all types of moisture. However, in some countries like the US, eucalyptus is not widely grown, so they may have a harder time finding this type of flooring than Vietnam. 19. Acacia wood floor If you’re looking for an eco-friendly choice of hardwood flooring, let acacia be the prime candidate. Besides the unique natural pattern, the acacia tree is also moisture resistant, so it will be easy to care for and maintain. The only downside of this wood is probably the limited size of the board, making installation more difficult.

This is the most common type of roof. The pointed roof is composed of two sides sloping down from the same starting point, forming two triangles on either side of the house. Pointed roof houses are suitable for countries with weather conditions with a lot of rain or snow because the slope of the roof makes it easier for snow and rain to fall, making the roof less heavy. The pointed roof has a simple design, requires less materials, and is easy to construct, so the cost is low. At the same time, the space below the pointed roof is wide and airy, so it can be used as a storage space or an attic bedroom. However, the pointed roof is easily affected by strong winds, if not firmly reinforced, it is easy to fall because the wind is easy to blow into the space under the roof, causing the roof to fall. 2. Tower roof This is a type of roof with 4 sides sloping down, with the same slope and relatively light slope to create balance for the building. Usually a tower-shaped roof will have 2 triangular faces and two trapezoidal faces. The tower-shaped roof is common in European countries as well as Vietnam and architects often use this roof for villas or garden houses. Tower roofs are recommended for areas frequently affected by storms. However, because of the complex structure, this type of roof is difficult to maintain. 3. Rubber roof Rubber roofing is a cheap, green, and durable option. Rubber roofs are usually large panels, easy to install. Waterproof surface, perfect for areas with humid climates. However, the aesthetic of rubber roofing can be too simple for some homeowners who want a difference for the home. 4. Flat roof Flat roofs are a popular design for homes in warm or dry climates. This type of roof protects homeowners from heat and sunlight. However, it is not ideal for areas with a lot of rain. In addition, you can create a living area, garden or mini sports field on the roof. 5. Roof falls This type of roof slopes in one direction. It can continue the slope of an existing roof, or separate, similar to a shed roof. The roof seems to be raised, making the work very noticeable. This is a permanent roof because water, dust and particles roll off more easily. The construction also makes it tough, able to face the harsh elements. Skillion roofs are ideal for contemporary urban homes, galleries and other small commercial buildings. The shape of the roof will immediately catch the eye. 6. Butterfly roof The butterfly roof looks like an inversion of the standard pointed roof. The basic design looks like a letter “V” (or butterfly) when viewed from a distance. This roof was popular in the twentieth century and many architects liked to experiment with this unusual roof shape. 7. Salt box roof The salt box roof is a type of pointed roof in which one side of the roof has a much longer slope than the other. Buildings with this type of roof usually have two floors in the front and one in the back; adding a sloping back porch is a structure that simply extends the building. The salt box roof is ideal for various modern and contemporary homes. You can create a patio under the higher roof, turning it into a cozy sitting area. 8. Curved roof Curved roofs are not a contemporary design. It appeared in the early 1920s as a solution to maximize storage space in barns. Curved roof is back in the modern world because of its unusual shape. It has a simple construction, is perfect for windy areas, and is easy to customize. 9. Dome Based on the curved design, the dome has a high visual impact. It is commonly used for the construction of buildings of worship, but variations of it appear in residential houses. This roof is unique, energy efficient and provides a great surface for decoration. 10. Pyramid roof The pyramid roof is a variation of the pyramidal roof. This roof is common in modern Victorian homes. The pyramid roof is well suited for windy areas and comes with its own insulation benefits. It also drains quickly when it rains. 11. Serrated roof The serrated roof looks like a series of ridges when viewed from a distance. This roof is popular in warehouses and factories because it allows natural light in. In the 21st century, serrated roofs are gaining popularity thanks to the trend of bringing natural light into the home. 12. Canopy roof The bonnet roof is a variation of the pyramidal roof. The edges of the roof extend beyond the walls, creating a shaded area resembling a bonnet. Some bonnets have a slight slope at the bottom. In modern homes, the bonnet is extended further to create a terrace or patio. 13. Roof with metal roofing The metal roof provides durability and strength. This roof can last from 50 to 100 years if well maintained. Metal roofs are perfect for windy areas, lightweight and ideal for reinforcing old structures. However, when it rains, the sound on the roof will make homeowners extremely uncomfortable. 14. Asphalt roofing sheet Asphalt shingles are popular roofing materials, especially in North America. They are cheap, easy to install, and can reflect sunlight better to reduce heat inside the home. But asphalt roofs are prone to damage from hail and water, so it’s not a good solution in the long run. 15. Slate roof The slate roof is made of natural stone, creating an expensive and luxurious look. It lasts a long time and doesn’t catch fire too easily. However, the combination of weight and fragility makes slate roofs more difficult to maintain. 16. Green roof Green roofs act as a means of planting trees, a growing trend in environmentally conscious architecture. It helps to create insulation, absorb water and deliver more oxygen in your environment. Green roofs can be applied to traditional houses and modern buildings.

Summer is the perfect time to go wild with a variety of dresses. However, in the summer of different years, we will see some styles of skirts with much more coverage, enthusiastically worn by connoisseurs. Summer 2021, in addition to flower dresses and babydoll dresses, there is a very popular style of skirt, everywhere, and the hot fashion item that is a shirt dress. Right from the name, we can immediately recognize that the style of the shirt skirt is the longer, more flowing version of the classic shirt. This is the reason that shirt skirts in general are scored in the elegance and discreetness, but also have the femininity and grace of dresses in general. And so, the shirt skirt is an item that you can absolutely wear in an office environment that requires attention and courtesy. But the beauty of shirt skirts does not stop there. The style of the shirt skirt always exudes a liberal and dynamic look, and thanks to that, the women’s appearance will be effectively rejuvenated, exuding sweetness and brightness, but without worrying about being “saw horns”. . It has both elegance and youthfulness, so obviously, shirt skirts are also very suitable for women to wear for a weekend or evening date. Shirt skirts in general have a loose shape, extremely comfortable to wear, helping to cool off on hot summer days. Equally interesting, the moderate spaciousness of the shirt skirt also helps to hide all the disadvantages of the body, making the appearance of women more beautiful and attractive. There are many versions of the shirt, and the shirt skirt also has many variations, from the most basic loose shape, to the light waist design, or sometimes with lovely details of sleeves, and variable. with a variety of textures. This is the reason why you can wear a shirt skirt all summer and not get bored, as long as you shop a variety of different versions. Shirt skirt is a very easy item in terms of shoes and accessories. You can mix shirt skirts with all the most trendy footwear styles such as: flat sandals, mule-shaped high-heeled sandals, white sneakers or pretty bow-tie doll shoes… As for bags, single style leather bags Simplicity will help ensure the style and harmony for the overall outfit, in addition, you can also adorn the set with a sedge bag to increase the liberal and flying look.

Introduction: From the previous generation of product electronic schoolbags to the current smart classroom industry, it has been ten or eight years, but this industry has not been very strong. Even in the near future, there are several incidents in Jiaxing, Bengbu, and the National Education Supervision Group. Controversies and policy pressures on this type of product are on the rise. What are the reasons?

Some time ago, I saw the point of view of a practitioner who believed that the chaotic nature of the smart classroom industry is because there has not yet been a product that can formulate industry standards and national standards.

But I think this concept is too easy to come up with, and it cannot be said to be wrong. Almost any industry can say the same before there are giants. I think this may be a fact, but it is not the whole fact. I think that thinking about this problem should be divided into horizontal and vertical. Of course, we must look at the problems of smart classroom products and the industry itself. Horizontally, we must see the differences between smart classrooms and other teaching information products.

Although the current smart classroom product forms include PAD, paper and pen, handwriting board, and feedback device (clicker), I think that except for the PAD end, other solutions are only used to solve the price problem of the PAD or the replacement of the screen problem. The plan is just a spare tire. Therefore, only the smart classroom on the PAD side will be discussed here.

The smart classroom industry can be subject to such a big controversy, and it can even be said to be the most popular product in the current teaching informatization (even the school information and communication industry feels that it has entered a plateau). I think it must be caused by a combination of many aspects. I will consider the following To decompose this problem in several dimensions:

1. Policy/concept level 1. Educational equity

   Smart classroom products are all students’ hands-on terminals, and objectively speaking, they can only be divided into flat classes, but this violates the principle of education fairness to a certain extent. But I think this issue is definitely not the most important, because we have too many ways to break education fairness.

   Various experimental classes, Beijing No. 4 Middle School/Chengdu No. 7 Middle School Online School, recording and broadcasting and even all three classrooms, as long as they are not implemented in the whole school at least for the whole year, education is equally unfair. From a horizontal comparison, I think education equity is certainly not the most important factor.

2. Children’s vision protection

I think this is relatively important because of policies, not social concepts. Myopia is really a very complicated problem. Looking at the electronic screen is only one of the factors. Now children are forced to stay up late at night to do homework, not exercise, and play with mobile phones. The impact may be greater than the time in the smart classroom.

Even to say something rebellious, children’s eyesight is never the most worrying issue for parents. As long as the education volume is serious enough, competition and pressure for entering higher education will be there. Don’t parents know that having so many cram schools a day is an overuse of their eyes? But is myopia important or is it important to go to school?

Of course, this seems a bit quibble. I don’t think it has no effect, but the vision problem must not be solved by the extinction wisdom classroom. I even hope that someone in the industry will do statistics. What is the proportion of myopia in the class that uses the smart classroom and the class that is not used, I believe there is not much difference.

1. Product price 1. Politics and procurement

   Generally speaking, we are not sensitive to the price of government procurement products, and the price of education informatization is almost outrageous compared with product prices in other markets. I haven’t felt it is a problem for so many years. But in the smart classroom industry, this is indeed a problem.

   From collective equipment to personal equipment, a substantial increase in the number is very difficult to achieve with the current investment in education funds. Therefore, many people in the industry believe that it is really hard to imagine what kind of support will be required to rely on the government to directly pay the bills, so they can only adopt the parent-paid model.

2. Parents pay

   In the two incidents in Jiaxing and Bengbu, the media repeatedly emphasized that the price of this smart classroom tablet was too outrageous, selling for 6,000 or 7,000.

   On the other hand, why is this tablet at this price? Are these manufacturers all black-hearted manufacturers without exception, and no one in the industry has a conscience? I don’t think so. I think there are two important factors that cause this price problem:

   I think this problem is very serious at present. In fact, it is not that no manufacturers have tried to break this transaction structure, but any reform, whether it is right or wrong, will always be obstructed by the old forces. To solve this problem, supply-side reforms and business model updates may be needed.

   It is more politically incorrect to say that after all these years, how has “education corruption” ever been mentioned on paper.

3. Dimensions of customer success: derived from the SAAS industry 1. Lack of the concept of customer success

   The concept of customer success was born in the United States. At present, the domestic SAAS industry is also widely used. I quote this concept to explain the problem of “satisfying customer goals”. The essence is the school level.

   It is very interesting that the SAAS industry has a basic understanding that when the number of customers comes up, it cannot rely on the customer success manager, and the whole industry is getting bigger and bigger, and the user perception is built up, and this dependence will naturally be weakened. But in the field of smart classrooms, the establishment of customer awareness is too slow.

   To be honest, product dusting is not the ill of smart classrooms, it is the ills of the entire education informatization and education equipment industry. There are so many products that schools use once or twice a year.

   I personally think that this problem is difficult to solve. It has something to do with the management structure of the school, the way teachers are hired, social status, etc. They have no motivation and sense of crisis to make progress, and can only rely on the personal pursuit of the principal and regional managers. , Even the pursuit of political achievement.

   As a result, the nonsense of “No service can’t be used” has been acquiesced in the entire industry.

4. Teacher’s personal questions 1. Some teachers’ acceptance of new technology/products

   Here is a quote from Douglas Adams’s three laws of science and technology:

   What is interesting is the teachers of K12, the average age of these 11-12 million people is 32-35 years old. There is quite a large group of people, and their acceptance of any new things, especially new technologies (which is new to them) is naturally very low.

   It doesn’t matter whether the product or technology is good or not, nor does it matter whether he has this need, but his notion that he is just a living being like a human being.

5. Smart classrooms are not being used in the whole school and the whole year

   This in itself seems to be a school reason, but why I put this into the teacher’s personal problem, because it will cause two factors that weigh on the teacher and make it very difficult for him to use the smart classroom:

   The teacher himself is just a wage earner (forget about the moral kidnapping of the engineer of the soul, the income is there, let’s talk about the affordability of a house), he needs to use a product to have an effect. Smart classroom cannot be said to be ineffective. I think the value of improving the classroom atmosphere is very high.

   But how can this effect be obvious to the teacher, and even more utilitarianly, how can I be able to go to work and fish and complete the work, how can I show it in the PPT, and how can I relate to performance? At this point, I feel that the smart classroom products have not been clearly thought out. At the simplest level, this is at least an “efficiency” issue.

   The above is my summary of the current ills in the smart classroom industry or products.

   The fact that an industry can develop to its current state and produce such a big controversy may not necessarily be caused by a single point of issue. On the other hand, solving any single-point problem is not enough to spur the rapid development of this industry.It is very difficult to establish a comprehensive understanding of this industry. I hope that

Over the past time, due to the long-term effects of COVID-19 epidemic, many employees quit their jobs and lost their jobs, so they chose to receive social insurance once.

Analysis by the period of time off waiting for pension entitlement shows that in the 2016-2019 period, the one-time social insurance beneficiaries are mainly employees after a year of leave without social insurance payment, on average, accounting for about 97%.

In addition to the difficulty of income, there is still a small proportion of employees still think “children trust their father, old depend on children”, not forming a habit when children pay social insurance so that when they get old they have a salary. retired, not dependent on descendants.

Many disadvantages for employees

The fact that employees register for one-time social insurance, leave the social insurance system by themselves is a worrying situation, not only directly affecting the interests of employees, but also affecting to the socio-economic situation, as well as to ensure social security for the people of the Party and State.

According to the calculation of the social insurance agency, if receiving social insurance once, the employee will lose about 1.14 months of salary for each year of social insurance payment before 2014 and about 0.64 months. salary for each year of social insurance payment after 2014. Not only affecting immediate profit, receiving one-time social insurance makes employees lose their chance to enjoy pension, there is no guarantee for life in old age.

Sharing worries about the increase in the number of employees receiving social insurance once in the first 3 months of 2021, Mr. Do Ngoc Tho, Head of the Policy Implementation Department of social insurance (Vietnam Social Insurance) said: “As the organization implementing the policy, we really feel very regretful when the employees choose the plan to receive one-time social insurance instead of choosing to preserve the paid time and wait for conditions to continue participating in social insurance, accumulate to enjoy the pension at the end of the working age. ”

According to Mr. Do Ngoc Tho, when receiving the one-time social insurance, employees will suffer a lot, because they are not old enough to retire, they have spent all their old-age pension. When you get old, you cannot receive pension benefits and depend on children, grandchildren and the society.

“If unfortunately sick, no card Health Insurance According to the pension regime, when old workers are still facing the risk of not being able to pay for medical examination and treatment costs after only one illness, long-term hospital stay, they may face poverty. hunger and exhaustion become a burden on families and society, ”said Do Ngoc Tho.

Mr. Bui Sy Loi, Deputy Chairman of the Committee on Social Affairs of the National Assembly emphasized that the status of receiving one-time social insurance makes efforts to mobilize and expand social insurance coverage to face many more difficult.

According to Mr. Bui Sy Loi, employees who receive one-time social insurance means that they leave the system to receive social insurance, self-stripping of the right to participate and enjoy social insurance benefits. especially long-term benefits such as retirement and death. This is an alarming and worrying situation in ensuring rights and policies Social Security long term for employees.

Mr. Do Ngoc Tho suggested that trade unions at all levels should coordinate with the local social insurance to focus on information and communication widely to employees about the superiority and long-term benefits of continuing to participate in insurance. society to workers; It is recommended that employees consider carefully, should not decide to enjoy one-time social insurance, but should reserve the time to pay social insurance so that when conditions permit, they should continue to participate in compulsory social insurance or participate. participate in voluntary social insurance, in order to have conditions for self-assurance and health care for themselves in the old age, at the end of working age./.
