  • Road to QatarBy Choi Ha-ram Cub Reporter, Sophomore of Public PolicyIn the winter of 2022, a championship will be held which will make the worlds football fans flutter. It is the FIFA World Cup, a quadrennial global festival. This World Cup will be held in Qatar in the Middle East area, and it will last for a month, from the 21st November until the 18th December. There is a six-hour time difference between Qatar and the Republic of Korea, so from the Korean perspective, most games will start late at night or early in the morning. This will not be a problem with the Koreans who often watch overseas football matches, but the people who do not will be tired. However, why not try to watch the World Cup game at the late time? That experience is going to give you a new enjoyment. Now, I will give you some of the basic knowledge that you will have to know to enjoy the 2022 Qatar World Cup.What is the World Cup?In the 2022 Qatar World Cup, only 32 countries who are selected through regional qualifiers from six continents (Asia, Africa, Europe, North and Central America, South America, Oceania) will advance to the World Cup. The country that advances to the World Cup final tournament, is going to play the group stage which will be combined into four countries in a group through a draw. The group stage is progressed by league method, playing a rotating game once with all teams in a group. Thus, every country has a total of three games in the group stage. If they win the game, they will gain 3 winning points, and if they draw, they will gain 1 point. The losing team will gain zero points. Like this, through the group stage, all winning points are added to make a ranking. The first and second country of each group will advance to a round of 16.-> The score of the F group at 2018 FIFA World Cup Russia (highest ranked: two teams, Sweden and Mexico, were advanced to a round of 16)The country that advances to a round of 16 will compete in the tournament. The tournament progresses by playing a series of matches where the winning team goes on to the next round. The final two teams compete to decide the final champion. This final tournament must determine a winner and loser, so there cannot be a draw. If the score is drawn, even after finishing the first half and second half, then victory and defeat is determined through an additional overtime. This extra game time has two 15 minute halves with a break in between. If the outcome is still not determined after the overtime, then the winner is decided through a penalty shoot-out. The penalty shoot-out consists of 5 players from each team who take a penalty, and the team that scores the most goals wins. The losing countries in the round of 16 will be eliminated immediately, and the winning countries will advance to the next stage. This same process is repeated, and the team that wins in the last stage will be the final winner of the World Cup. Hopefully, this will help you to enjoy the World Cup, watching each match and guessing which country will be the champion.Official Match Ball of the 2022 World CupThe official match ball that will be used in the 2022 Qatar World Cup is Al Rihla, which means travel. The Al Rihla ball flies faster and more accurately than conventional balls. Speedshell technology, which is comprised of 20 square pieces of material, treated with polyurethane, increases the accuracy, speed, and flight stability of the ball. Additionally, focusing on sustainability, Al Rihla is the first eco-friendly official match ball of the World Cup, which is made of water-based ink and water-based adhesives. The production company, Adidas, said that the ball was inspired by the cultures, traditional architectures, and the national flag of Qatar. They explained that they used purple and dark-blue to express Qatar, and the speed of a football game getting faster. Lets look forward to what kind of history will be written in this World Cup with the new official match ball.source by Adidas official online site.Football Rules, which are More Fun When You Get To Know Them1. Penalty Kick (PK)A penalty kick is an opportunity given to the attacking team, due to a defensive teams foul. If the defense teams player fouls in the penalty area, the attacking teams player (non-foul team) faces the goalkeeper one-to-one and tries to kick the ball into the goal. The probability of strikers to get a goal increases, because there are no defenders who defend the goal area. The position that the penalty is taken from is 12 yards away from the goalpost. At that time, the defense teams goalkeeper has to stand on the goal line until the attacking teams striker takes the kick. In addition, other players except the kicker and the goalkeeper, must be at least 10 yards away, behind the penalty mark.2. OffsideOffside might be the hardest concept to understand for a beginner. However, you do not need to be afraid. Offside will be easy to understand, when you realize the strikers location. The conditions of determining offside are as follows. First, the attacking team player is located ahead of the ball in the opposing teams position. Second, the defense team cannot have more than two players between the opposing team and the goal line. Third, the attacking team players get a pass from their own teams player from behind. When these three conditions are qualified, an offside foul is declared. However, receiving a ball directly from the offside location with a goal kick, corner kick, or throw-in does not apply an offside foul. If you still do not know, scan the QR code below. This video will help you.The Players of South Koreas National Team that You Should Pay Attention to in the 2022 Qatar World Cup1. Heung-Min SonI think there are very few people who do not know this player, especially in Korea. Son has been a Tottenham Hotspurs striker in the English Premier League for 7 years. When he plays the game in the national team, he mostly performs actively as a winger. Sometimes, he plays as a center forward, but he mostly plays a role in creating opportunities for the center striker, through breakthroughs in the left wing. When Son gets a pass, he usually passes it on to center forward, but sometimes he directly brings the ball to the goalpost and scores a goal. That is why we have an expectation for Son where he can create a goal when he holds the ball. At the time of the 2018 Russia World Cup, there was a saying that it is nice to give all the balls to Son. Lets watch the match, and see what performance he will give in this World Cup. Probably, he will correspond to our expectations.2. Min-Jae KimHe is the necessary defender of South Koreas national team. He currently plays for Fenerbahce SK in Super Lig which is in Turkey's football league. His position is center-back. As a sweeper of the team, he defends the ball from the opposing team, and even creates a chance for his own team through a long-cross. In the national team, he not only accomplishes all the roles as a defender, but also sometimes participates in an attack, and looks for a heading goal opportunity from a corner kick with his tall height. In the final Asian qualifying round of the World Cup, the opposing team had difficulty in conducting an attack, because Min-Jae Kim blocked the ace striker of the opposing team. When you watch a World Cup match, it would be nice to pay attention to the performance of Min-Jae Kim who is called a monster defender. Perhaps, you will be able to feel reassured due to this player.How to Enjoy the World Cup1. With Fried Chicken and BeerIf you watch the match with the delicious food, the pleasure will be doubled. However, if the foods consist of fried chicken and beer, that will be perfect! In South Korea, people usually eat fried chicken and drink beer, when they watch the match in the football or baseball stadiums. Also, on the day of an important match, if you order fried chicken at a restaurant, it will be delivered later than usual. Koreans eat fried chicken as much when they watch a game. If the team loses on the day that you have fried chicken and beer, you can console yourself with fried chicken and beer, and if the team wins, you can rejoice even more. If you still do not have any experience with eating fried chicken and drinking beer while you watch a football match, you can try it during the World Cup.2. Singing a Cheering SongFor victory, Oh, victory for Korea, If you are a Korean, you might have heard these songs at least once in your life. When you sing the cheering songs, the players who listen to the cheering will gain strength. Not only will the players benefit, but also the audience who cheer will get more excited. Some people visit the stadium because they like the mood of the cheering section. If you watch the match directly in the stadium, you are sure to sing a cheering song. Probably, you can feel the same thing when you are in the stadium. If you can not watch the game in the stadium because of the COVID-19 and other reasons, sing a cheering song at home. There will be a new enjoyment waiting for you.Paulo Bento, manager of the South Korean national football team, has made many changes to the team. The result is that he emphasizes the build-up of football from the early stages of preparing for the World Cup. Now the Korean teams pass play is much more developed than before. As a result, Korea has made history because the Republic of Koreas team has advanced to the World Cup finals for the 10th time in a row. Lets cheer together for the Korean national team to do well in this World Cup. Also, lets expect to see the national team players show us what they have prepared. I am sure they will do just fine. Even if the result is not good, do not be disappointed. The reason they have advanced to the World Cup finals is great in itself. Lets cheer with a mature sports fan attitude, hoping the players will come back safely and with positive results.

  • Flexible Phones?By Yoo JayReporter, Senior of Material Science and EngineeringNow, we are living in an age of innovation. In 2007, a man wearing jeans and a black turtleneck took a small device out of his pocket. Then he completely changed the concept of cell phones. We can text a message, make a phone call, send an email, and use IT technologies, just by touching the phone screen. Thanks to this convenience, smartphones have become a part of our daily life. According to the Gallup Korea poll, conducted in 2021, the percentage of Korean adult smartphone users is currently 95 percent. In addition, according to data from the Korea National Statistical Office in 2021, adults use smartphones on average for four hours a day. Now, we feel that smartphones are like an essential part of our body. So, why dont we know what will happen on the mobile phone, which is just like a part of our body?Since people do most activities using a cell phone, there is one essential thing that mobile phones must have. It is portability. The latest smartphones are portable, but engineers are studying these items to increase their portability. How comfortable would it be to fold your cell phone like paper and put it in your pocket? In fact, many engineers are researching a variety of FormFactors (FormFactor : the physical shape of things and their appearance) that can be folded, and rolled. The display that can transform its form factor is called a flexible display, and many experts say that this technology is going to bring the next innovation to future cell phones. Surprisingly, some products have already been developed and are on the market. Lets figure out about cell phones according to the flexible stages.Stage 1 Flexible Display:Durable DisplayDurable Display phones have a curved screen as a whole. Since flexibility is required to bend the display, the substrate should be made from an elastic plastic, instead of the existing unbending glass. This technology was applied to G Flex that was launched from LG Electronics. This product fits our usage more comfortably. That means that the speakers and microphones can be positioned as close as possible to the ears and mouth. It can help users to hear better, and also increases the clarity of their voice for thelistener.Stage 2 Flexible Display: FoldableRollable DisplayRollable display is a flexible display that allows cell phones to be rolled up like toilet paper. In contrast, a foldable display is a flexible display that can be folded. A radius of curvature of the substrate around 10mm is required for a stage 1 flexible display. For stage 2, it needs a considerable decrease in the radius of the curvature of the substrate. So, it is essential to the macromoleculization of the substrate. This technology was applied to the Galaxy Z Flipthat was launched from Samsung Electronics in 2020. We can fold this product and put it in our pocket. You can enjoy a large 6.7inch / 17cm screen by spreading the display. Also, it can be spread out at various angles, so we can freely use our hands to do other things during the video call.Stage 3 Flexible Display: Stretchable displayThe ultimate goal of the flexible display is a stretchable display. It can be bent, folded, or stretched in the desired directions. After removing the stretching force, it returns to its original materials shape. For this technology, it is essential that the substrate, electrodes, and shields have a high restoration force. Once this technology is developed, we will be able to put our cell phones in our pockets like paper, and go to school. Then, take them out of our pockets for team projects, spread them out on large screens, and use them together.It is not the amazing thing that cell phones are folded anymore. Just 10 years ago, the foldable phone was a fantasy product in SF movies. However, how is it now? You can often see advertisements for Z flip, a flexible product, while passing through the street. The Stretchable displays, which are the last stage of flexible displays, have not yet been developed, but many research results continue to come out. Soon, stretchable displays that stretch like rubber bands will no longer be a surprise.

  • A gift? Avoid This!By Lee Jun-hyeong Cub Reporter, Senior of Chemical and Biological EngineeringI want to buy you shoes, but Im always worried that you will leave. -SG Wannabe-Sunflower - As you can see in the lyrics of the song, you may have heard at least once, that if you present shoes to your lover, they will run away. In Korea, giving shoes as a gift to your lover is a kind of taboo. There are cases where people think that gifts may lead to big mistakes or relationships may go wrong as a result. In that case, what kind of gifts are taboo in other countries?USALilies: They are used at funerals, and are not given as gifts because they represent death. This is the same in the UK and Canada.Do you want a tip?They like practical gifts, and it is polite to immediately check the gifts when you receive them. ChinaTurtles: In Chinese, the pronunciation of the word for turtle is similar to that of ghost, so its better not to give presents that are related to turtles.Bouquet: Flowers mean a short life, and they are usually taken to funerals.Handkerchief: This is related to sadness, breakup and death, so avoid it as a gift.Do you want a tip?I recommend traditional alcohol because they love drinking alcohol.Congratulatory money or gifts must be paid in even numbers, and condolatory money must be paid in odd numbers.They like red, but they do not like white, black or blue colors because that means unhappiness. JapanKnife: It represents suicide and relationship disconnections. Handkerchiefs also mean relationship disconnections.White color means death. Thus, do not give whitethings, or use white wrapping paper.Do you want a tip?They prefer kimchi, seaweed, and ceramics.Do not use shiny packaging and ribbons.FranceRed rose: This means proposing. Therefore they only exchange it with their lovers.Perfume and wine: French people have a clear personal preference, so we do not recommend perfume gifts. Gifting wine is not recommended because it is similar to giving soju in Korea.Carnations: They are used for funerals, so do not give them as a gift.Do you want a tip?They drink a lot of tea, so werecommend tea gifts.Also, they eat jam on bread every morning, so I recommend jam gifts.GermanyWhite, black, and brown wrappers and ribbons are considered ominous colors, so it is better to avoid them.The number, 13: This number is considered ominous in Germany.Do you want a tip?In Germany, it is polite to take off the wrapper of the bouquet when giving flowers, and unlike when giving them to Chinese people, it is customary for Germans to give them in odd numbers. HungaryRed rose: There could be a misunderstanding because it means love feelings.Wine: Wine gifts are not recommended, because they have strong pride in the wine they produce.Do you want a tip?Unlike Germany, they must wrap a flower gift.PolandIt is good to give flowers as a gift because they like them, but you must not give them in even numbers.Do you want a tip?Practical and easy gifts, such as lighters and writing utensils, are recommended.ArgentinaWine: It is rich in wine and also a major producer of leather, so it is recommended to avoid wine and leather gifts.Do you want a tip?Tariffs on imported alcohol are quite high, so Scotch whiskey or French champagne are recommended. BrazilKnife: It means the end of a relationship, like Japan and Mexico.Black and purple gifts: They think that black and purple are ominous colors.Do you want a tip?We recommend giving small electronic devices.We have studied many items that are considered to be rude if they are given as gifts in different countries. There are some parts that you might understand, and some parts that you will think are very unusual. However, they are all related to each different countrys culture and history, so we need to have an attitude to respect and follow those ideas. So, if you have a chance to give a present to your foreign friends, you can consider the information in this article, and make sure you can give them a present that they will appreciate, and not one that will be considered offensive in their culture.

  • Science Meets SportsBy Yoon Ji-yeon Editor-in-Chief, Junior of Electrical EngineeringThe bad call is also a part of the game. Those who like sports may have heard this at least once. When the team or athlete that you are supporting gets the unfair results made by a referees bad call, the fans try to control their mind by reminding them of those words. As a result, it has become a part of sports culture.However, the players who have tried hard can not be damaged by misjudgments forever. People have tried to solve this problem by introducing science technology into sports. Then, specifically, what kind of technologies have been brought in different types of sports? It is fun to just watch, but if you have more knowledge of the technology, it will be much more fun! Lets find out in detail through this article.1. SoccerVideo Assistant Referee (VAR)Soccer, the most popular sport in the world, is one of the most representative cases in which scientific technologies are used. The VAR technology officially debuted in 2016 FIFA Club World Cup, and it has been widely used in Europes major football leagues, UEFA Champions League, and K-League.In important situations like a goal, penalty kick, red card, etc., we often can see the referees draw a square with two hands, and put their hands on the ears. This is the scene where the referees demand a VAR decision and exchange their opinions with the judges in the VAR room. The VAR judges who are in the VAR room are checking the game through the 30 cameras which are installed throughout the stadium. They communicate with the referees in the stadium in real time and deliver the reading results. In this process, the average reading time is around 12 seconds, which is much shorter than the time spent protesting against misjudgment. This meaningful change helps run the game smoothly.The most representative example of the game in which VAR changed the outcome is the 18-19 season Champions League quarter-final between Tottenham and Manchester City. In this game, the VAR decision was based on whether Fernando Llorentes goal was a handball foul or not. In conclusion, VAR showed the goal was not a handball foul, and Tottenham scored the goal. In the extra time ofthe second half, Manchester Citys Raheem Sterling scored a goal, and it made the game lean towards Manchester Citys victory. However, the VAR decision was made on whether the situation was an offside situation, and the result was offside. Eventually the goal was canceled, and as a result of the first and second round, Tottenham could advance to the Champions League semi-finals. Two VAR decisions determined their result.2. TennisHawk-eyeThe tennis ball usually moves at an average speed that easily exceeds 200km/h. This makes it really hard to make an accurate decision depending on the referees eyes. So, tennis has used scientific technology for a relatively long time, compared with the other sports. Hawk-eye debuted in the 2006 U.S. open, which was about 10 years earlier than soccer.Hawk-eye is a technology which is much more sophisticated than the VAR. 10-14 high-speed cameras are installed throughout the court, and they capture the movement of the ball at 340 frames per second. Based on images captured by high-speed cameras, each frame is analyzed and reproduced as a graphic video in a three-dimensional space to determine the judgment. This graphic video is open to referees, audiences, coaches, and players in real time. This is a characteristic and advantage that is compared with other video technologies.Each athlete can request using Hawk-eye up to three times per set. If three challenges fail in one set, they can not request any more, even if a clear misjudgment has happened. So, the players must use the challenge chances strategically. According to the statistics for the 2017 U.S. open, the percentage of decisions changed as a result of using Hawk-eye was less than a third, showing 28 percent for mens singles, and 24 percent for womens singles.Scientific technologies have been used in various sports in addition to the two cases introduced in this article. Baseball has instituted a Robot Umpire to discern the strike zone, and volleyball also uses Hawk-eye for In-out replay, and VAR technology to check for errors, like net touches.In the past, it was hard to imagine a machine making a decision rather than a human referee. However, nowadays, it is a common situation, making more precise decisions. These changes are responding to the sweat and efforts of athletes. Lets look forward to fairer decisions which will be made by more advanced levels of technology.

  • Ride the Metaverse!By Jeong Hyo-bin Reporter, Senior of Chemical and Biological EngineeringThe word Metaverse is a combination of Meta, which means virtual and transcendent, and Universe., meaning a virtual universe.We feel awkward about the concept of the Metaverse, but we are already accustomed to it. There are many metaverse games including Roblox, Minecraft, Animal Crossing and MapleStory. All of the aforementioned games can create avatars in the virtual world, and avatars can make meetings and do economic, social and cultural activities together in the virtual world, the same as in the real world. This cyberspace is the Metaverse.Amazingly, there was a metaverse in the past, too. In 2003, Linden Lab developed the 3D virtual world service called Second Life in the US. However the service was quickly forgotten by Facebook and Twitter. In Korea, there was a metaverse concept platform with a service called CyWorld that communicated in the virtual Minihompy. As such, we have communicated in the virtual world, so we can say that we are accustomed to the concept of the metaverse. With the development of digital technology, many things have become possible in the virtual world, such as CyWorld and the world of games. The concept of the metaverse has only recently been created, and that makes us feel it is something new. However, we have lived in the metaverse already.The Metaverse is attracting attention as a content and platform. The Metaverse has become a communication platform for young people in non face-to-face situations, as a result of COVID-19. The metaverse platform (such as Roblox, Fortnite, etc.) can be seen as both a platform and contents at the same time. For example, some people enjoy Roblox as a metaverse content, and use the game world as a platform by producing and selling items to generate revenue. Companies also use the metaverse platform as a method of promoting their products.BTS first released a choreography version of Dynamite on Fortnite. Fortnite is a metaverse with more than 10 million concurrent users. Avatars of global fans enjoyed watching Dynamite music videos at a virtual space concert hall within the game. If you buy BTSs choreography emoticons in the game, your avatars can dance along. Likewise, companies promote and generate revenue through the metaverse.Rui, a virtual YouTuber (V tuber), is a cyber singer who wears virtual faces. Ruis face, as you can see on YouTube, is a face that does not exist in reality and has no problem with portrait rights. These virtual humans are made to look like cartoon characters, but they are also made into hyper-realistic virtual faces that are indistinguishable from real human faces. Metaverse is already making profits by using these models to create advertisements or idol groups such as Eternity.Not only games, but also social activities are carried out through the metaverse. In Korea, Soonchunhyang University hosted the Metaverse Entrance Ceremony for the first time. An avatar of 2,500 freshmen gathered in an online space that implemented a real campus playground in virtual reality. Avatars wore varsity jackets and listened to the presidents greetings, and had conversations with seniors and professors in cyberspace.The virtual world and the real world are getting closer, due to developing technologies and diversifying platforms. However, there are many problems such as illegal activities and judicial rights within the metaverse, and virtual world poisoning.We should enjoy the metaverse platform with the right perception. However, it is also important that the laws and preventions that regulate and control problems must also be established as the pace of technology development quickens. We cannot enjoy the metaverse without it being under some kind of control.

  • The Next Station Is an Eco-Friendly CarBy Yoon Ji-yeon Editor-in-Chief, Junior of Electrical EngineeringWhen you think about cars, what first comes to your mind? We usually think of refueling at a petrol station, or of complex engines. These classic characteristics of cars have been emerging since the late 19th century when internal-combustion engine cars were first developed.As the engine cars usage increased, they became indispensable in our daily lives. However, the side effects also emerged continuously. By burning gasoline and diesel, whichare both fuel for car engines, fumes are emitted, consisting of carbon dioxide, carbon monoxide and hydrocarbons. Also, exhaust gases have caused environmental pollution, like ozone depletion and fine dust increase. As a solution to these problems, the eco-friendly cars have come into the limelight. So, what kinds of eco-friendly cars are there, and what are the benefits of driving eco-friendly cars? Lets find out.Electric CarThe history of the electric car is older than you thought. The first electric car was made in the 1830s, about 30 years earlier than the first internal-combustion engine car. However, the battery was too heavy, and it took too long to charge. That made the electric cars decay, unlike the engine cars. However, electric cars have come back into the spotlight as environmental pollution has worsened around the world.Electric cars use secondary batteries that charge directly by supplying electricity, and drive motors using the electric energy stored in the battery. As a result, electric cars have a huge advantage that they dont emit any atmosphere pollution matter or greenhouse gases. In addition, these cars dont use any consumables, like engine oil, fuel filters etc., and these advantages allow reducing environmental pollution and cost by consumables. They also have regenerative braking ability, and this makes the electric car able to charge on its own.Hybrid carHybrid cars have both an internal combustion engine and an electric motor. Hybrid cars use their engines and motors to suit their use when driving.It boasts more than a 40 percent higher fuel efficiency than ordinary internal combustion engine vehicles, because it has a system that mixes engine and motor driving in five driving types: Start and slow, acceleration drive, high speed, deceleration drive, and stop. The low use of fuel creates less environmental pollution. Also, it has regenerative braking ability, like the electric car, and it makes the hybrid car able to charge on its own. There is also an advantage with hybrid cars that they can be recharged much quicker because they are also charged by the engine, unlike the electric cars which take a long time.Hydrogen-electric carHydrogen-electric cars are not widely known, compared to electric cars and hybrid cars. The commercial vehicles of Hydrogen-electric cars have only recently been launched, and the research is still ongoing. The hydrogen-electric cars are powered by fuel cells that produce electricity by the reaction of hydrogen and oxygen in the air. In other words, this car is powered by the electrical energy that is transformed from the chemical energy of hydrogen. In this process, this car only emits water and heat. This is why hydrogen-electric cars are called zero-emit vehicles, and are in the limelight as eco-friendly vehicles.In addition, hydrogen-electrical cars can purify the air. They suck the air, purify it, use it for hydrogen fuel cells, and then exhale clean air back into the exhaust vent. This has given the hydrogen-electric car the nickname of the Moving Air Purifier. Taking advantage of these benefits, the hydrogen-electrical cars are used as large sized busses, and public institution vehicles.The benefits of eco-friendly carsThe government is also planning to actively distribute such eco-friendly cars. The Korean government distributed 136,000 eco-friendly cars in 2021, and has set a goal for distributing 7,850,000 eco-friendly cars by 2030. To achieve this goal, the government and local governments are also making efforts to provide subsidies and other benefits.If you have an electric car, you can get subsidies of up to 8 million won. However, this differs according to the price of vehicles and the local governments that provide the subsidies.In the case of hybrid cars, the consumption taxes included in the price of cars can be reduced by about 1 million won when purchasing cars. Besides this, there are various other benefits like motorway tolls, 50 percent off, public parking fees, 50 percent off, etc. You can get more specific information about the model, and benefits through the QR code on the right side.To solve the problem of environmental pollution, engineers and scientists are working on new technologies. To help the planet, why dont we buy eco-friendly vehicles with no emissions? This will make the environment more healthy in the future.

Wise Mask Etiquette

  • Wise Mask EtiquetteBy Park Hyeon-su Chief Editor, Senior of English Language and LiteratureAs COVID-19 is spreading throughout the world, wearing a mask is becoming a more natural etiquette. The mask has become an indispensable necessity in our daily lives to protect our health. However, masks have a one-time use, so the amount of mask waste is also enormous. These discarded masks are so light that they fly off easily during the garbage disposal process. Unfortunately, abandoned masks have been found trapped around parts of the bodies of helpless wildlife, causing many animals, such as young seagulls, to suffer. It is very important to wear masks to fight this disease. But, how can we dispose of our masks wisely?1. All types of masks, regardless of material are discarded as general waste.According to the Environment Ministrys recycling separation and discharge guide, masks are registered as general waste. All kinds of masks, regardless of material, such as vinyl-coated paper, nonwoven fabric and cotton, are treated as general waste. Therefore, they must be placed in a pay-as-you-go bag to be incinerated. Because used masks are contaminated, you must wash your hands and disinfect for hygiene after discarding the mask.2. Fold the contaminated surface out of reach, tie it with a string, and discard it.Because the surface of the mask is exposed to the outside, it is contaminated with various viruses and dust. Therefore, be careful not to touch the surface when removing the mask. To discard the mask, first, grab the edge and fold it twice so that the outer surface goes inside. Second, roll it so that it doesnt spread out and tie it with a string. Third, spray sterilizers or seal them in plastic bags, etc. Afterwards, you can put it deep in a standard plastic bag to prevent it from leaking out during collection. Also, you must disinfect your hands after you throw away the mask. This is because hands may have been contaminated during the process of taking off the mask and folding it.3. Disinfect, seal and collect them in a waste bag at the public health center.If used by a person with a confirmed diagnosis or one who is in self-quarantine, their masks, gloves, and disinfectants are all classified and treated as medical waste. Therefore, this waste should be sterilized and placed in a dedicated envelope-type kit provided by a competent health center and kept completely sealed. The envelope is later collected or disposed of separately by visiting an isolation site at the health center.4. Crop Mask String CampaignThe Korea Environment Corporation said that it is a good idea to tie up the mask strap instead of rolling it around. However, the material of the mask is light and the strap is loosened easily. The loose mask has a large area for its weight, so it flies well. Recently, the issue of wildlife suffering from masks has spread around the world. This is because a mask was seen tied to an animals leg after flying over a garbage dump.As a result, many animal rights groups and celebrities have launched campaigns and challenges to cut mask straps on social networking sites. The British Royal Society of Animals (RSPA) pointed out on Twitter that abandoned mask ear straps are causing animals to suffer because they cannot untie human waste trapped on their bodies. Kwon Joon-soo, a professor at Seoul National University Hospital, recently said on his personal SNS that, there are cases in which animals are tied up after trying to find food in garbage cans. I thought I should cut off the strap of my mask and throw it away. Lets cut the string with scissors and throw it away. As this fact became known, the mask strap-cutting campaign quickly spread.The act of throwing away contaminated masks on the streets for fear of taking them home can cause environmental pollution as well as the spread of COVID-19. Therefore, lets make sure to practice wise mask habits for a healthy daily life.

  • Who Is Responsible for Climate Change?By Lee Woo-Seong Reporter Senior of Mechanical engineeringSince the Industrial Revolution, humans have released over 1.5 trillion tons of carbon dioxide (CO₂) into the atmosphere and the emissions keep rising. However, emissions need to get down to zero. In recent years, the consequences of this level of pollution have become more serious and visible. Every year, horrible records are broken. We've had more heat waves, more glaciers melting, and the lowest amount of ice ever recorded at the North Pole. The only way to limit this rapid climate change is to decrease our collective emissions quickly. Although all countries agree on this goal, they have not agreed to be responsible or to bear the heaviest loads. The developed countries point at their own efforts to reduce emissions and the fact that large developing countries are on the rise. For example, China is currently releasing much more CO₂ than in years past. On the other hand, developing countries argue that emissions by the West are lifestyle emissions, while for developing countries, they are survival emissions. Others call rich countries hypocrites that got rich by polluting the earth without any restraint and now expect others not to industrialize and therefore stay poor. So, who is responsible for climate change and CO₂ emissions?Which countries emit the most carbon dioxide today?In 2017, humans emitted about 36 billion tons of CO₂. More than 50% came from Asia. North America and Europe followed with 18% and 17%. While Africa, South America, and Oceania together only contributed eight percent. China is by far the world's largest emitter with 10 billion tons of CO₂ every year, or 27% of global emissions. It is followed by the USA with 15% and the European Union with around 10%. Together, this is more than half of the world's CO₂ emissions. So it is clear that without the willingness and action of these three industrial blocs, humanity will not be able to become carbon neutral and prevent severe climate change. Next on the list is India at seven percent, Russia at five percent, Japan at three percent, and Iran, Saudi Arabia, South Korea, and Canada all just short of two percent. The top 10 countries are responsible for 75% of global emissions. But, if we only look at the current situation, we are not getting the full picture.Which countries have emitted the most in total?If we look at emissions throughout history until today, the outlook changes drastically. The US and the EU both knock China off the top spot. The US is responsible for 25% of the world's historical emissions having emitted 400 billion tons, mostly in the 20th century. In second place is the EU at 22 percent. China comes in third at just under 13 percent, around half of the USA's contribution. India's contribution shrinks to 3 percent along with the whole of Africa and South America. The UK is responsible for one percent of annual global emissions but takes five percent of the historical responsibility. Germany, producing two percent of emissions per year today, has contributed almost six percent, as much as the whole of Africa and South America combined. So the narrative that rapid climate change is really the responsibility of the developing world is hard to defend if facts matter to you.So who should take the responsibility?Many of today's richest countries are in a convenient position. They have become rich over centuries of fossil fuel burning and industrial production. They have a large historical footprint, and their wealth means they still emit a lot per person. But, their countries annual emissions are now dwarfed by other countries, because the giant that is China is finally catching up, and other giants like India are on their way. Many Germans, for example, wonder how if Germany only accounts for two percent of yearly emissions, it can have a meaningful impact on reducing emissions. The answer is simple. For one, the richest countries have the resources, highly educated workforces, and technology to develop low-cost, low-carbon solutions and spread them around the world. If we don't want poorer countries to become as fossil fuel-dependent as we are, we need low-carbon technology to be cheap and available. If the rich countries of the West finally decide to try to make a major effort to slow rapid climate change, the rest of the world would follow, because it would have no choice. China is the largest CO₂ emitter today, and it's China's responsibility to grow in a way that will make it possible to transition to a zero-carbon world, in time. Others acting irresponsibly yesterday is a horrible excuse for repeating the same mistakes today. Climate change is a global problem, and no country can fix it alone. Working out who's responsible is not as simple as it seems, and in a way, it's a daft question, but one that has plagued international politics for decades. In the end, it's pretty simple. Each person can follow these easy steps to reduce their carbon footprint--recycle, take public transport.

  • An Era in whichEco-Friendliness is EssentialBy Joung In-young Cub Reporter, Freshman of Electronics ControlHave you ever seen a post uploaded on SNS with #In-Courage? This post made people aware of the wide use of unnecessary plastic in everyday life. As such, we can confirm that the movement related to Zero-Waste for environmental protection has recently become more active.Zero-Waste is a term that means the principle of designing all resources and products used in everyday life to be recycled so that no waste is buried or dumped in the sea. By 2010, major media and distribution companies from around the world, as well as influential individuals, began to join the movement.In addition, some states in the U.S, including California, are embracing Zero-Waste policies, which are evolving into a social movement. As people's interest grows around the world, consumers are also trying to build their own Zero-Waste lifestyles. Follow these steps to start your own Zero-Waste life.1. How to Practice Zero-Waste 5RAmerican Zero-Waste influencer Bea Johnson emphasized the practice of 5R for a Zero-Waste lifestyle through his blog and book.2. Companies taking the lead in recycling and reuseThe practice of zero-waste is really not that difficult. Using products from companies that practice Zero-Waste in line with the changing trends of society is another way. For example, here are some companies that have made plans to reduce waste.2-1) SpriteColored plastics are made of composite materials, so they have the disadvantage of being difficult to recycle. In response, Sprite, a global beverage company, has boldly given up on green, a symbolic color that has been maintained since its launch, and is selling its drinks in a transparent package that can be recycled.2-2) PatagoniaPatagonia, a popular U.S. clothing brand, produced outdoor clothing using recycled polyester extracted from plastic bottles, old fabrics, and used clothes.2-3) GoogleGoogle has reused expired data servers through its own campaign called Moonshot, and six of its 14 data centers have been built so that there is no trash going back to landfills.3. Zero-Waste Shop for EarthIts not just corporations, small businesses are also beginning to practice Zero-Waste. The number of the Zero-Waste shops is increasing greatly both at home and abroad. These stores are developing different strategies to avoid creating disposable waste. Korea is home to an inspiring new Zero-Waste shop.3-1) Seongdong-gu, Seoul, The PickerThe Picker was the countrys first Zero-Waste shop to open in 2016. Everything here is sold without packaging. This can reduce the amount of plastic used as packaging and also create eco-friendly habits such as preparing containers or bags for vegetables or grains.3-2) Seodaemun-gu, Seoul Bottle FactoryThe Cafe Bottle Factory in Yeonhui-dong does not offer disposable cups. Instead, they lend tumblers to guests who visit without a personal cup. Also, unless the customer requests it, the receipt is not printed. They try to reduce unnecessary waste discharge to match other Zero-Waste shops. They also hold Your Bottle Week, an annual disposable cafe festival, to spread the Zero-Waste coffee culture through cafes near Seoul.Zero-Waste may seem cumbersome, but we must study and practice this lifestyle and take these small extra steps that can make a big difference. Then, for the sick Earth, we can coexist in a cleaner environment.

  • HMR, Hot Trend In The Food WorldBy Lee Seo-jin Cub Reporter, Sophomore of Material Science and EngineeringHave you ever heard of Home Meal Replacements? Recently, they have become a major trend in the food industry. They are so hot that new terms have been made to describe them and they are also called a future food. What is the reason for HMRs popularity?HMRs are packaged products of pre-processed ingredients that can be eaten after simple cooking. In general, when we eat food, we follow the traditional steps of purchasing ingredients, prepping them, cooking, eating, and cleaning up. HMR was created with the aim of reducing these processes and efforts, and giving consumers greater freshness compared to conventional frozen foods.There are four types of HMRs: Ready-to-eat, Ready-to-heat, Ready-to-cook, and Ready-to-prepare.RTE(Ready-to-Eat)RTH(Ready-to-Heat)RTC(Ready-to-Cook)RTP(Ready-to-Prepare)Foods can be eaten without heating or cooking, such as lunch boxes, kimbap burgers, and sandwiches.Food can be eaten after a simple cooking process, such as soup, tang, and jjigae.Foods, such as frozen dumplings and frozen fried rice, that have undergone simple processing.Food ingredients, such as recipe meal kits, which are prepped and portioned for simple cooking by the consumer.The first HMR in Korea was curry. The 3-minute Curry, launched in 1981, is a first-generation HMR that focuses on convenience. The second generation of HMR focused on freshness. Refrigerated and frozen foods became popular. Since 2013, a 3rd generation of HMR has been made to include cup-bab, soup/tang/jjigae, and Korean side dishes. From 2015 to the present, premium daily meals have emerged, and a 4th generation of HMR has been created in collaboration with famous restaurants and chefs. HMR has once again grown into a fifth generation. The keyword in the 5th generation of HMR is meal kits. Meal kits, with ready-to-prepare food, are becoming more popular as the coronavirus era continues. Because pre-portioned meal kits can be picked up at markets or delivered to your home, they are more convenient. And, theyre more fun to prepare for yourself.There are several reasons for the rapid growth of the HMR market. First, according to a recent survey by the National Statistical Office, the number of single-person households has increased significantly. Single people tend to buy processed foods, rather than making food at home. Due to this demographic shift, the development, production, and sales of HMR have also increased to meet this need.Secondly, online delivery has developed. Online malls are suitable for selling processed HMRs. If food companies sell products directly through their own online shop, they can reduce commissions paid to retailers and easily identify customers purchasing trends. This information can be used for marketing and developing new products. From a consumer's point of view, they get the advantage of receiving products comfortably delivered to their door at a cheaper price than offline.Third, there is the popularization of convenience stores. Convenience stores are easy to visit at any time, and we can easily buy a small amount of goods. Therefore, convenience stores close to houses are the best place for single-person HMR sales. Also, convenience stores are highly accessible, so it is easy for companies to advertise their products to consumers.What are the disadvantages of HMRs? First, there is the environmental concern about the use of disposable plastics that many HMRs are packaged in. Additionally, we have to check the expiration dates carefully. In particular, fresh RTCs have a short shelf life, so be careful. In addition, HMRs are often heated in a microwave, so we have to check the precautions before using a microwave.Precautions for Microwave UseStep 1Step 2Step 3Check if glass, paper, porcelain, or polypropylene is microwave safe when used.Follow the heating time listed on the package or recipe.Use gloves to remove food from the microwave.With the investment of many companies, the science and technology used in HMR is getting better and better. These days, with the new COVID-19 restrictions, getting food delivered is a safer way to have healthy meals. As new HMRs are developed, people have the chance to prepare a variety of new recipes for their families, or for themselves if they live alone.
