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?

  • 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 World

  • 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.

  • BrexitBy Park Hyeon-su Chief Editor, Senior of English Language and LiteratureThe European Union (EU) is a European political and economic community. It was established after the leaders of the 12 countries in the European Community (EC) agreed in December 1991 to form a European Union (Treaty on European Union). The purpose of the EU is promoting economic and monetary integration and political integration.The treaty went into effect in November 1993 in Maastricht, Netherlands, after a ratification process by each country. The EU forms a national body with legislative, administrative, and judicial ministries. In other words, the European Parliament serves as the legislature, the executive committee as the administration, and the judicial tribunal as the judiciary. From such a well-organized EU, Britain carried out Brexit on Jan. 31, 2020. So what is Brexit?Brexit: A newly combined word from Britain and exit.In other words, it refers to the United Kingdom's exit from the EU. Politically and economically, the UK, one of the strongest countries in the EU, is expected to have a significant impact on the EU by withdrawing. The British Empire, once a superpower that ruled the world until the early 20th century, is still the world's seventh-largest economy as of 2020. Moreover, Brexit has developed into a global issue, as the UK is a powerful country that culturally affects the world, as well as it being a permanent member of the U.N. Security Council.Brexit has many pros and cons in and out of the UK. Now, let's hear the opinions of those who wanted to stay in the UK and those who wanted to leave.Remain supportJ. K. Rowling, author of the Harry Potter series, was a representative EU remainer. Before the vote, she lashed out at those who pushed for Brexit, calling them monsters and villains. Shortly after the results of the referendum were finalized, she responded on Twitter with an extreme response of Goodbye, UK, and to her followers' request to "do something," saying, "I've never thought more earnestly that I need magic."Withdrawal supportMichael Caine, currently living in the USA, was one of the few supporters of withdrawal from the British entertainment industry. Asked by The Guardian why he supported this withdrawal, he said, It wasnt about the racism, immigrants or anything, it was about freedom, revealing that his choice was for a Britain free from the oppression of the EU and that he had no regrets about it. However, as the British economy has deteriorated due to Brexit and the U.S.-China trade war, Caine confessed his feelings, saying, I'd rather be a poor master than a rich servant.So, what is the impact of Brexit on Korea?Although the UK voted to leave the EU in January 2020, there has been little immediate impact and they will maintain their previous relationship until December 31, 2020.Last year, South Korea and the UK reached a bilateral free trade agreement in principle for fear of a "no deal Brexit," which is likely to cause much confusion.For Britain, South Korea is one of the key allies in the Asia-Pacific region, along with Japan, Singapore, Australia, and New Zealand. At present, Korea is one of few countries with a population of more than 50 million that maintains a high standard of living and economic strength. Right now, only Britain, France, Germany and Italy, which are G7 countries, have larger economies than Korea. KEPCO is said to be interested in Britain's Moorside nuclear power plant construction project, while the UK is also eyeing South Korea's nuclear power plant construction technology and possible future joint projects in South Korea and the UK.As of January 2021, the UK will have a new relationship with the EU and will have to forge new global trade agreements. It will be interesting to see how the UK moves forward in the coming year, however, it will be a long time before we can determine whether Brexit was for the best or not.

Is Vegetarianism a Hot Trend? Fact-Checking Vegetarianism's Pluses and Minuses 이미지
Is Vegetarianism a Hot Trend? Fact-Checking Vegetarianism's Pluses and Minuses

  • Is Vegetarianism a Hot Trend?Fact-Checking Vegetarianism's Pluses and MinusesBy Gi Myeong-seok Cub Reporter, senior of JapaneseIf you look around these days, you can easily find companies and restaurants are releasing products and menus for vegetarian customers to access their dishes. You can even buy vegan ramyun, vegan kimbap, and bean-based hamburgers at convenience stores. This speaks to the increasing number of consumers who now have a vegetarian diet in modern society. The number of vegetarians in Korea, estimated by the Korea Vegetarian Union, reached about 1.5 million as of last year. Compared to 10 years ago, the figure has doubled. Many celebrities, like Kim Je-dong, Jeong Ryeo-won, Liam Hemsworth, Ellen DeGeneres, and Anne Hathaway are also vegetarians. Vegetarianism is increasing, not only in Korea but also around the world. Gradually, many people in Korea are shifting to a vegetarian diet for a variety of reasons, such as improving the health and constitution of the body through a vegetarian diet and protecting the environment by reducing meat consumption.Vegetarianism is becoming a hot trend, and many people are trying to eat this way. But, is it really okay for us to eat only vegetables? What will be the change to our bodies?In this article, we would like to learn more about the vegetarian diet.What is a vegetarian?The vegetarian diet refers to avoiding meat and making a diet centered on vegetables. Vegetarians eat vegetables, fruits, nuts, and beans, rather than eating meat. But, vegetarians can also be categorized into seven major categories depending on what animal food they may include in their diet. Here are the seven types of vegetarian diets.Raw Food Vegan: this is a person who excludes all food and products of animal origin, as well as food cooked at a temperature above 40.5 C. This diet includes raw fruits and vegetables, seeds, nuts, grains, legume sprouts, plant oils, sea vegetables, herbs, and mushrooms.Vegan: a person who does not eat or use animal products. Vegans eat cooked products from the above list.Lacto Vegetarian: a person who abstains from eating meat and eggs, but eats dairy products.Ovo Vegetarian: a person who abstains from eating meat and dairy, but consumes eggs.Lacto-Ovo Vegetarian: a person who abstains from eating meat, but eats eggs and dairy products.Pescatarian: a person who does not eat meat but does eat fish.Flexitarian: one who consumes a plant-based diet with the occasional inclusion of meat, eggs, or dairy products.Why Do People Become Vegetarian?In the past, due to the influence of religion or poverty, there were many vegetarian meals. However, nowadays the reasons that people have chosen to become vegetarian have changed. In countries like New Zealand where meat is not as expensive, people often choose to be vegetarians for reasons other than cost. Parental preferences, religious or other beliefs, and health issues are now among the most common reasons for choosing to be a vegetarian. Many people choose a vegetarian diet out of concern for animal rights or the environment. And, lots of people have more than one reason for choosing vegetarianism.Advantages of VegetarianismThere are also many benefits to our body through a vegetarian diet. Since meat consumption has increased in modern times, vegetarian food is also recommended to many people for the prevention of adult diseases, by controlling excessive protein and fat consumption. Excessive meat consumption increases blood sugar and increases weight. Fat in meat blocks blood vessels, raising the risk of heart attack. Compared with meat eaters, vegetarians tend to consume more vitamins C, E, and magnesium. As a result, they're likely to have lower total cholesterol, lower blood pressure, and lower Body Mass Index (BMI), all of which are associated with longevity and a reduced risk for many chronic diseases.Also, eating a vegetarian diet can help you increase the intake of fiber, achieve weight loss, and prevent the risk of cardiovascular disease. It can also reduce cancers caused by meat and processed foods and provide a natural antioxidant effect from fruit and vegetables.There's some evidence that vegetarians have a lower risk for cardiac events, such as a heart attack or death from heart disease. In one of the largest studies, vegetarians were, on average, 25% less likely to die of heart disease.Is the vegetarian diet the best for the body?There is something good about eating a plant based meal. However, the body must have all five nutrients evenly to keep healthy. That's why a vegetarian diet that you start for your health may sometimes be harmful to your health. The reason is that there may be nutrients that are not included in your vegetarian diet. Vegetarians have to be careful to include the following key nutrients: protein, calcium, iron, vitamin D, vitamin B12. If you dont eat red meat, you lack protein that lowers immunity and reduces body energy. Hair is also made up of protein, so there is a possibility of hair loss. The other problem is lack of iron. Consuming low iron can make your skin pale and cause severe headaches. If you're choosing a vegetarian diet, the most important thing you can do is educate yourself. If meat, fish, dairy products, and eggs are not going to be part of your diet, you'll need to know how to get enough of these nutrients, or you may need to take a daily multiple vitamin and mineral supplements.So, if you're considering going vegetarian, keep these tips in mind.There are numerous research-proven health benefits to following a vegetarian diet, but only if you’re doing it properly and not substituting meat with processed or high-fat vegetarian products.Both lacto-ovo vegetarians and vegans need to make sure they are getting adequate nutrition. It’s a good idea to purchase a book on how to follow a vegetarian diet, or to meet with a nutritionist to outline what a few days of meals looks like.Be aware of how much of your diet is made up of nuts as a source of protein, especially if you’re trying to lose weight. An ounce of nuts is about 180 calories and 5 grams of protein. You should be getting between 20 to 30 grams of protein per meal. You’d have to eat thousands of calories worth of something like nuts in order to get the amount of protein you need to be healthy. Nuts are a healthy food, but they are also high in fat and calories, so be sure to round out your diet with a variety of vegetarian proteins.Modern society has become rich in food. You can get meat at a cheap price and enjoy BBQ parties on weekends with your family and neighbors. But, rich food isn't the only good thing. Excessive consumption of meat can also harm our bodies. Reckless eating habits eventually make us sick. Whether you are an omnivore or choose a vegetarian way of life, the most important thing is to keep appropriately planned meals. We have to be smart about the consumption of every ingredient. Regardless, it is most important to think about what you eat and what kind of ingredients and foods are healthy for you. Well-balanced meals make our bodies healthy and healthy thoughts and ideas come from healthy bodies.

  • Preview: 2020 Tokyo OlympicsBy Yoon Ji-yeon Cub Reporter, Freshman of Electrical EngineeringThe Olympics, which are held once every four years, are coming back. The 2016 Olympic Games were held in Rio de Janeiro, Brazil and now, the 2020 Olympics will be held in Tokyo, Japan. July 24th to August 9th, 2020 will be a passionate time. Before then, lets take time to learn about the 2020 Tokyo Olympics.The symbols of the Tokyo Olympics[photo]The Olympic emblem is called the face of the Olympic Games. The emblem shows the individuality of the host country. Tokyos Olympic emblem embodies the traditional check pattern of the Edo period. It is called いちまつもよう [市松模様] in Japanese. The pattern has tetragons of various shapes and sizes in the color navy blue, which is the traditional color of Japan. Each tetragon represents the thoughts and cultures of different countries, and the overall round shape symbolizes the diversity and harmony of countries.Also, the Olympic and Paralympic mascots were created based on the emblem. The Olympic mascots name is Miraitowa. This name was formed from the words future (未来,) and eternity (永遠) in Japanese. The Paralympic mascots name is Someity. This name comes from So Mighty in English and the pronunciation of cherry blossoms in Japanese and the pink pattern of Someity is similar to the flower.Special sports events of the Tokyo OlympicsIn 2017, the executive committee of the International Olympic Committee (IOC)confirmed 33 sports entries that are going to be held at the Tokyo Olympics. This means these games will have the most diverse sporting events in Olympic history. This is because of the rule change which allows the organizing committee of the host venue to choose up to 5 sports.The five sports that were added on the organizing committees recommendation are Baseball s check the story behind these selections and these sports.Baseball s baseball and womens softball be selected as Olympic sports. This effort combined with the popularity of baseball in Japan, so it was registered as a sporting event for the Tokyo Olympics.Softball is a sport played by women that is based on baseball. So, the game rules of the two sports are very similar. The game is played by two teams, and they switch between offense and defense. If a batter walks home through first, second, and third base, she will score. However, while baseball is played for nine innings, softball plays for seven innings. Also, there are some differences in equipment, like the larger ball and shorter bat.KarateKarate is a traditional Japanese sport. This is Karates first time becoming an Olympic sport. This sport was selected because of the organizing committees recommendation. Karate has two kinds of game rules. One is Kata, these are a series of offensive and defensive movements targeting a virtual opponent. The other is Kumite. In Kumite, two players face each other and attack using their hands and joints. But a karateka, a practitioner of karate, must stop his or her attack before hitting their competitor. Otherwise, the karateka who attacked their competitor gets a penalty.Sport ClimbingSport climbing will make its debut in the Tokyo Olympics. Sport climbing is divided into three categories. First is speed climbing, in which climbers compete on the same course and their climbing time is ranked. Second is lead climbing which is a competition to climb as high as possible in a given time. Third is bouldering in which climbers have multiple attempts to reach the top of a boulder. Their score is based on how well they can reach the top, then also on how successfully each attempt has been made.Each athlete competes in all three categories, and the final ranking is determined by the total score of the three categories.SurfingSurfing is one of the sports that is popular with young people. The Tokyo Olympics will be the debut of surfing as an Olympic sport. Surfing is distinguished by the size of the board, using a longboard or shortboard. But, only the shortboard will be used in the Tokyo Olympics.Surfing is scored in a complex process. The winners are determined with scoring based on the type and difficulty of performance and skills, along with speed, power, and flow. Five referees score the surfers performances. Each surfers highest and lowest scores are excluded, and the average of the remainder is their score. This process is similar to the figure skating scoring process.SkateboardingSkateboarding is also debuting in the Tokyo Olympics as a sport. Skateboarding has two detailed events. First is street which is held on a straight course featuring stairs, handrails, curbs, benches, walls and slopes. Second is park which is held on a hollowed-out course that looks like dome-shaped bowls. This course features a series of complicated curves. All participants must show their various skills and tricks. Evaluation considers the degree of difficulty of the tricks, height, speed, originality and the composition of moves.Surfing and Skateboarding have a special point of sameness. After confirming that surfing and skateboarding were selected as Olympic events, the sports community had a cold reaction. This is because surfing and skateboarding have long been considered as an act of self-expression. So, many surfers and skateboarders didnt regard them as competitive sports. This recognition even made some people file an online petition with antipathy.Will the Tokyo Olympics be a safe Olympics?The Olympics is a festival of people from all around the world. Every four years, people all over the world spend time in front of the TV or visiting the stadium to cheer for their athletes. But, there is a big issue that has been pointed out since 2013 when Tokyo was confirmed as the venue for the 2020 Olympics. That is radioactivity.In 2011, a huge earthquake hit Japan and cracked a nuclear power plant causing an explosion. This leaked a large amount of radioactive material. This was a major accident (the highest level) on the International Nuclear Event Scale, and this level was the same as the Chernobyl disaster. Although its been nine years since then, the danger of contamination continues.The biggest worry is using materials from Fukushima. As 70% of Fukushima is a mountainous area and it is hard to clean polluted soil, experts say most of the trees are still polluted. However, Fukushima timbers were used to build the village plaza that will be used for athletes rest. Their intention was to wish for the revival of the disaster areas. Japans Forestry Agency said it would be safe because they got rid of the timbers bark and they went through the process of measuring for radioactivity. However, reporting by foreign press revealed the measuring process was too sloppy, and criticism of safety has continued.Also, some stadiums are located near Fukushima. A typical case is the Fukushima Azuma stadium where the baseball and softball events will be held. This stadium is only 67 kilometers away from the Fukushima nuclear power plant. In addition, black bags of polluted soil near the stadium were seen through satellite imagery in July 2018. This caused concern about visitors possible radioactive exposure and many people were shocked.IOC stated the stadiums near Fukushima are safe and they dont have any plans to change location. However, the radioactive measurement of the stadium was about 0.5 Sv/h which is more than twice the safety standard (0.23 Sv/h). Doubts about whether the stadium is safe to hold Olympic events have been discussed, and 23 organizations from around the world have joined a group that has renamed the games Tokyo 2020the radioactive Olympics.The Tokyo Olympics have caused these concerns. The main purpose of the Olympics is peace. In addition, safety is another main value that is in the spotlight. I hope the value of peace will continue to thrive and that theres no threat to anyones safety.

  • Microplastics Attack HumansBy Kim Do-won Cub Reporter, Junior of English Language and LiteratureModern people have high a level of dependence on plastics as if they cannot live without using plastic things. However, if these plastics threaten human beings by changing into an invisible poison, can we keep accepting its use?These days, the concern about microplastics, which is plastic that has divided into lots of small pieces, is increasing rapidly. We can see many campaigns to reduce microplastics on the streets and in the news. Why have microplastics become an object of campaign? Why do microplastics have peoples interest like this?What are Microplastics?Microplastics are small plastic pieces under 5mm. Microplastics are classified as primary microplastic and secondary microplastic. Primary microplastics were produced separately from the beginning. Secondary microplastics are made when things that were large plastic products disintegrate. We can see these microplastics easily in our daily life. Microplastics exist in many plastic products and cosmetics that we use, especially as minute scrubs in foam cleansing products. In these products, they are called Microbeads and they are a primary microplastic under 1mm. Recently, they have been considered a cause of marine pollution.Microplastics flow to the sea because their particles are too small to filter during water treatment processing. When they glitter in the sea, reflecting the sunshine, seabirds mistake them for fish eggs and eat them. Fish also take them in with water during breathing. Finally, they die because of a visceral cleft which is a tear of the internal organs. Microplastics bring grave danger and problems to the ecosystem.Microplastics are also found in cloth which is made up of synthetic textiles (fabrics). During the process of drying clothes made from synthetic textiles, microscopic fibers are divided from the cloth. These flow to the sea through the sewer. They cause the same problems by accumulating in creatures internal organs.Bail to RiskMicroplastics cause lots of problems, such as destroying the ecosystem. The Environmental Pollution Prevention Center in China conducted animal experiments related to microplastics. The experiments concluded that microplastics accumulate in the liver, kidneys, and intestines, increasing oxidative stress. Oxidation stress is caused by the loss of balance between the oxidizing substance in the body and the corresponding antioxidant, resulting in higher oxidation rates. In humans, increased oxidative stress causes protein damage and diseases, such as diabetes and cancer. It also confirmed that increased levels of microplastics can be greatly toxic to the brain. However, these experiments have a limitation in that the target was an animal. In fact, this is the biggest reason scientists are wary of microplastics. They say they don't know exactly what microplastics do to humans yet.According to the "Ocean Pollution Fact Sheet" released by the United Nations in 2017, more than eight million tons of plastic are introduced into the sea every year. It is also said that there are currently about 51 trillion microplastic pieces in the ocean. In addition, regarding a recent study, modern people take in an increasing number of microplastics every week.On August 14, the BBC reported that scientists also found more than 10,000 microplastic particles per liter of snow in the Arctic. Microplastics, which used to be found only in the ocean, are now being evaporated into the air and then are dropped with the snow. This is proof that the air, soil, and sea on Earth are now polluted by microplastics, affecting the whole ecosystem.As time goes by, microplastics will pile up all over the earth and in our bodies. However, it is still not clear exactly what the risks of microplastics are to mankind. Microplastics are like a time bomb that is not exploded yet.A solution that can stop the pollutionThe whole world struggles to escape the danger of microplastics. States in the U.S. have declared a ban on Microbeads in succession in 2015. Since 2017, the U.S. administration has pushed for a water pollution prevention law that would ban the use of microbeads in all washing products. International corporations that produce cleaning products, such as Johnson & Johnson, also rushed to declare a stop to producing products with Microbeads. In Germany, a system that provides a deposit refund for returning empty bottles to stores has raised the recycling rate to 95 percent. In addition, the number of times plastic can be recycled has reached 40 to 50 times, which is a huge effect on reducing plastic waste. Biodegradable plastics that can be completely decomposed by microbes in nature also provide a fundamental solution to the problem of microplastics contamination.However, these systems, campaigns, and technologies have no effect if they are not implemented by consumers in real life. There are already many campaigns that can be conducted in real life, such as using tumblers and reducing the use of plastic straws. If you look around a little and take small actions, they can be a great help to save the earth.
