There was a time when the article, “Both lack of sleep and excessive sleep induce dementia.” This is after long-term observation of middle-aged and elderly groups who continue to lack sleep or have excessive sleep resulted in an increase in the incidence of dementia compared to the general group (7-hour sleep).

The core of scientific research is the verification of ‘causality’ between the two phenomena. For the above results to be scientific, it is necessary to find out whether the amount of sleep determines the occurrence of dementia or whether the two phenomena have been observed together by accident. In other words, scientific research is to find out whether the ship fell accidentally when the crow flew, or whether the ship actually fell due to the impact of the crow flying with branches.

In the course of scientific inquiry, researchers approach the truth through the interaction between induction methods that derive general principles from data obtained from experiments and observations and deductive methods that derive new principles by developing logic from proven principles. The reliability of the conclusions made by induction depends on the perfection of the observation. However, most scientific experiments lack the amount of data observed. Based on poor data, we make the most plausible (low probability of being wrong) conclusions and test them with new experiments to see if the hypothesis is correct. In philosophy, this is called abstraction. This is not only a universal scientific research method, but also a method by which doctors diagnose diseases or judges make judgments. This is why misdiagnosis and misjudgment are sometimes inevitable.

Conversion is especially widely used in life science research. This is because the proven principles are far from sufficient due to the nature of the field, and observation cannot be made indefinitely. Statistical analysis methods play an essential role in reaching conclusions from limited data. In other words, the right or wrong of the conclusion is only judged by statistical calculations. In general, a conclusion with a 1% or less probability of being wrong is accepted as right for now. Therefore, it is dangerous to think that this conclusion is a firm truth. It should not be forgotten that the results may vary when the observation is performed from more, wider, and various angles.

You have to judge through extensive experiments and observations

Another difficulty in human-related research is the difficulty of conducting hypothesis verification experiments in humans. At this time, the experimental animal model is mobilized. The conclusion is drawn based on the results of the experiment conducted by setting the experimental animal in a state similar to that of a human. It inevitably has a limit to the difference between the human body and the model animal, but it is the best possible observation. In the last article, the conclusion that “continuous low sleep time can increase the risk of dementia” is supported by various human and animal experiments. On the other hand, studies on the causal relationship between excessive sleep and dementia are not yet sufficient.

No intentional manipulation of data

The universalization of scientific thinking is an important factor in advanced society. Discourse disguised as science often confuses society. Despite the analysis that the average value of electromagnetic waves near the THAAD (High Altitude Area Defense) base was one-thousandth of the harmful standard, the danger was exaggerated and nearby residents were terrified. Rumors that “Koreans easily get mad cow disease and have holes in their brains” have frightened the entire nation, which is based on reports that mad cow disease is found in U.S. cattle and that the risk of Croitsfeld Jacob disease (brain tissue destruction, unrelated to mad cow disease) is common.

The biggest taboo in science is intentional data manipulation. However, in the scientific community, errors, whether intentional or real, are usually corrected by the unique self-purification function. This is because in order for the paper to be published, it must pass the screening of fellow scientists. Errors that could not be filtered out during the screening process may be revealed during the verification process of scientists after the paper is published. For example, 17 years ago, due to the authenticity of embryonic stem cell research data, the entire society suffered measles beyond the scientific community.

It is also the basic teaching of Buddhism that there is nothing in the world that arises without relying on causal relationships. We look forward to a mature society where scientific thinking becomes common sense. It is a world in which the attitude of blindly blaming the crow for the ship’s fall is no longer accepted.

Mars is a very cold and dry desert planet, but there are places to get water in the polar regions. This is because there is a glacier made of dry ice made by cooling water and carbon dioxide in the polar regions of Mars. However, unlike Earth, carbon dioxide is a cryogenic environment where it can exist as a solid, so the possibility of life is slim.

However, in 2018, scientists from the European Space Agency (ESA) analyzed radar data from the Mars Expression and published a study that showed that liquid substances seemed to be under the Martian Antarctic glacier. In fact, many lakes under glaciers have also been found on Earth. This is because no matter how cold the Antarctic is, water can melt underneath the glacier for several kilometers and form a lake by various heat sources such as friction between glaciers and bedrock. Therefore, the results of this study were considered theoretically sufficient. And if there is liquid water under the Martian Antarctic glacier and other energy sources exist, life can exist, so it has attracted academic attention.

Scientists at NASA’s Jet Propulsion Laboratory (JPL) secured additional Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) radar data to verify the claim. Masis was developed to investigate geological conditions in orbit by measuring the degree of reflection of radar through the surface and ice. The degree of reflection of the radar varies greatly depending on the type of material, but also depending on whether it is a liquid or a solid. Therefore, you can check the lake under the thick ice.

The research team analyzed 44,000 data measured over 15 years in detail and found that there were not one but several radar signals suspected of being a lake under the Antarctic glacier. As a result of analyzing the lake candidates under dozens of glaciers, the research team noted that there are lakes in shallow places than expected. For example, the signal of the lake could be found even at a depth of 1.6km, which is estimated to be about -63℃.

If there is a real lake and it does not freeze at this temperature, it is likely salty water with a lot of minerals dissolved. Another possibility is that the temperature is much higher than expected due to heat sources caused by other geological activities such as volcanic activity and hot springs. Either way, the glacial lake at a relatively shallow depth will be an important goal for future Mars Antarctic exploration.

Scientists believe that ancient Mars was a warm, liquid water-rich environment like Earth. And just as life was born on Earth during this period, life may have been born on Mars. If Martian life existed in even a simple form of bacteria, one of the places that can maintain its existence so far is the isolated lake. However, in order to find out whether there is a real lake and what is in it, we have no choice but to drill it and examine the inside of the lake.

However, it is not an easy task to explore the inside of the lake through the ice so deep on Earth. Mars goes without saying. Thus, real exploration will be a distant future, but mankind will someday challenge this challenge to solve questions about life on Mars.

Humans looked at the stars in the sky, measured their direction, found their way, named them, and connected them with stories. Although it varies slightly depending on the region and country, it feels mysterious to say that it is an inevitable universal response to nature, looking at the shining stars under the same sky.

Constellations are quite familiar to us, too. Historical records such as 고Goryeosa≫ and 조선Chosun Dynasty Annals≫ show our ancestors’ interest in astrology that predicted the future of the royal family and the country through astronomical phenomena, which continues to the present day and still predict constellations according to their birth dates.

If you ask anyone if they know constellations, I think they will get more than one answer. That much, I am familiar with constellations, but when asked if I have ever found them in the sky, I can expect different results. The reality may be that modern people who spend their entire days indoors at school, work, and day-to-day and are busy sleeping because they are tired at night do not have enough time to enjoy the night sky except for a short travel time.

However, sometimes when you look up at the sky, unexpected joy comes. On a difficult day, sometimes a shining star can be a great comfort, and on a trip that has left easily, it can make a perfect day. In the hope of becoming the starting point for this big and small joy, I would like to easily solve the basic common sense that you can enjoy constellations around the summer night sky.

Brightness of the Star

The brightness of a star is different. The grades are divided according to the brightness, and there are largely ‘appearance grades’ and ‘absolute grades’. As can be inferred from the word, the apparent grade is the brightness of the celestial body measured on Earth divided by the grade. The grades range from negative to positive, and the lower the number, the brighter the star. The absolute rating is a little different. If the apparent rating is based on observations on Earth, the absolute rating is based on the assumption that all stars have the same distance and then the brightness is graded.

The lower the apparent level, the easier it is to observe with both eyes, and thus we can see that the brightness of each star varies. Then, in order to find constellations in the night sky, wouldn’t it be a good idea to try to observe them based on the brightest stars? That’s why we need to find the alphabet.

Alpha stars are the brightest stars in a constellation. It’s called in the order of brightness after the Greek letters, the brightest star is the alpha star, then the brightest star is the beta star, and then the gamma star. It leads to this order. This nomenclature originated from Johann Weyer, a German astronomer, and is named after him.

*In principle, it is true that the names were given in the order of the brightness of the stars, but many exceptions have been found in modern times.

If you see an exceptionally shining star in the night sky, it is likely someone’s alpha star. Alpha stars can be a good indicator for us to match the pieces of stars in the night sky.

Color of stars

Not only is it bright, but each star has a slightly different color. When you look closely at the stars in the night sky, you sometimes feel that there is an exceptional red or blue light, and it is not just a feeling, but it is highly likely that the color of the star has been properly measured. In conclusion, the reason why the colors are different is that the surface temperatures of stars are different.

Stars emit their own light and emit energy, and the lower the energy, the wider the wavelength, the red light, and the higher the energy, the narrower the wavelength and the blue light. In other words, the lower the temperature of the star, the red light, and the higher the temperature, the blue light.

This principle can be easily found around us, and the color of the gas stove’s flame can be said example. The color of the outermost flame is blue and red toward the inner center, which also varies depending on the temperature.

Along with the brightness of the star, color is also one of the good indicators to distinguish stars in the night sky. Once you’ve finished identifying the elements that distinguish the characteristics of stars, it’s time to learn about the constellations that stars gather together.

The Big Triangle of Summer Triangle

There are three stars representing summer constellations. The large triangle formed by these three stars is called the “summer triangle.” In addition to summer triangles, there are spring curves, autumn squares, and winter triangles, and stars of constellations representing the night sky of each season.

If an alpha star acts as a good indicator to find a constellation, the summer’s Great Triangle can be a good guide to finding constellations in the summer night sky. If you look up at the countless embroidered night sky as if stars were pouring out, it seems to be sprinkled without rules. However, if you search for constellations one by one based on the brightest stars, you may wonder that it is not a sea of irregular dots, but a well-matched puzzle. (Although it is true that constellations are all just names and stories given by mankind.)

Back to the subject, Vega, Deneb, and Altair are the stars that make up the Great Triangle of Summer. These stars are alpha stars in constellation Geomun, alpha stars in constellation Swan, and alpha stars in constellation Eagle, respectively. Vega’s apparent rating is about 0, Altair is about 0.8 and Deneb is 1.25 and can be observed without difficulty with the naked eye on a clear day.

If you have found these three alpha stars that make up the Great Triangle of Summer, it is now time to find out the representative constellations of Summer. First of all, it is the swan constellation, which can be said to be the most colorful constellation in the summer night sky. The alpha star deneb is located near the tail of this swan constellation, and is shaped like a cross around it.

Next is the constellation of Eagle, where the alpha star Altair is located near the eagle’s head, and has a cross similar to the constellation of Swan. Finally, there is Geomungo, where the alpha star Vega belongs. Vega is said to be the fourth brightest star in the sky with a noticeable blue hue. Perhaps if you find an exceptionally bright blue star in the summer night sky, it is likely to be a Vega.

to the end

There is an interesting story in the summer night sky. On the way through the Milky Way, Swan constellation is located as if flying, and with this swan constellation in between, Bega, an alpha star in Geomungo constellation, is called Jiknyeo Castle, and Altaire, an alpha star in Eagle constellation, is also called Gyunwooseong. It also tells a sad story of waiting for July 7th, with the Milky Way in between.

Knowing that the brightness and color of the star are different, and if you can find an alpha star and find a figure guide representing the season in the night sky, you can say that you are now ready to enjoy the night sky. However, in order to leave the pleasant long journey of the night sky, you can enjoy it more abundantly if you use good tools. To do this, one last tip is to join the constellation map app.

There are many types of apps, but there is no significant difference in basic functions, so it will not be difficult to use them at your convenience. I’m also using an app, and if you run the app and bring the screen to the sky like you’re taking a picture, you can know all the information on stars, planets, satellites and meteors that you can’t see with your bare eyes. It provides various functions and information for astronomical observation, such as the ability to take astronomical photographs by adjusting exposure or sensitivity or the ability to inform observation conditions, so it can be useful.

If you notice a star that shines especially in the night sky, try to infer based on the season, brightness, color, etc. and run the app to compare. It may be the starting point for you to fall into the infinite world of celestial bodies.

On an exceptionally clear and dark night, when stars are visible in the sky, I hope you can stare as far away from the surrounding lights as possible. There will be three stars and four stars in the sky where only one or two stars were visible, so you will be able to see more stars.

Among the tall buildings, it is too easy to pass by unless you look up consciously. It is never easy to find when you can’t afford it, but on the contrary, it is also the star of the night sky to me that you find when you have a hard time.

I hope that a clear and dark night will come before this summer, which is good for observing stars, and that cultural lovers will be able to find and count the constellations in the summer night sky. Small, shiny, shining stars from 10 billion years ago will be able to give a sparkling comfort to the tired mind.

Netflix held a press conference on the 4th and expressed its position on the controversy over network usage fees. Netflix reiterated its previous position to focus on reducing traffic through ‘Open Connect’. Instead of paying a monetary fee, Netflix is currently suing SK Broadband for a technical problem.

Netflix, which is in conflict with ISPs (domestic Internet service providers) over network usage fees, said it will focus on ways to reduce traffic through “Open Connect.” This is a repeat of Netflix’s existing position that it will contribute to network usage fees in a technical manner instead of paying economic costs.

OCA reduces traffic by at least 95%…Repeat “Technical Solution”

Dean Garfield, vice president of policy at Netflix, held a press conference in Dongdaemun Square Seoul, Jongno-gu, Seoul on the 4th and said, “We will cooperate with ISPs in a way that effectively provides Netflix streaming but does not burden the network.”

“We have invested as much as 1 trillion won so far to create OCA (Open Connect Alliance), our own CDN (content transmission network),” he said. “Through this, we have reduced network traffic from at least 95% to up to 100%. Over the past year, ISPs around the world have saved 1.41 trillion won through OCA, it added.

OCA is a technology developed by Netflix 10 years ago and can be called its own CDN. Netflix claims that using OCA, data is delivered directly to the ISP, so there is no relay access fee. In addition, it can be installed anywhere inside the ISP network, so there is no additional cost even if the content is received from a long distance.

Dean Garfield, vice president of policy at Netflix, is hosting a “Netflix Media Open Talk” on the 4th at JW Marriott Dongdaemun Square Seoul. “Most Internet users in Korea pay Internet usage fees based on 200MB per second,” said Vice President of Netflix, adding, “If you use OCA, the traffic caused by Netflix users is 3.2MB per second even at peak time.” Even assuming the most traffic, Netflix accounts for 2% of the average Internet fee.

Vice President Dean also stressed that in addition to OCA, additional technologies are being developed to establish a stable traffic environment. Typical examples are the ability to encode the same video file into multiple versions according to the bandwidth of various viewing environments, and the method of delivering videos of the same quality through less and less bandwidth by improving the compression method.

“I’m not paying any network usage fees.””OCA is an ISP’s choice”

As Netflix repeated its existing position to bypass the network usage fee problem due to technical problems, questions continued at the press conference on Netflix’s position on the payment of network usage fees and reverse discrimination issues.

Asked about the discrimination issue, saying Netflix does not pay network usage fees to overseas ISPs and does not pay network usage fees to Korea, Vice President Dean said, “We are building commercial partnerships based on marketing or financial transactions on set-top boxes.”

Also, it is not true (to pay for the network usage fee). I don’t talk about things that aren’t true in public, he said. “If there is an ISP who receives network usage fees, wouldn’t you show up?”

When it was pointed out that Disney, which is planning to release Disney Plus in the domestic market, and Apple, which released Apple TV+, are paying the cost to CDN, some CPs use CDN to provide content. However, Netflix’s position is a little different.

“Netflix has created its own CDN, OpenConnect, in order to create an ecosystem called the Internet,” he said. “Disney and Apple each made the most reasonable choice for their companies.”

“Each ISP can choose whether to use open connect or not,” he said. “Netflix continues to innovate while providing information and insights.” We are waiting for the ISP to choose open connect,” he added.

SKB and lawsuit, KCC’s “passing” isn’t it…”Hope to cooperate”

Dean also mentioned the ongoing trial of network usage fees with SK Broadband. Netflix is suing SK Broadband for refusing to pay network usage fees. Although it recently lost the first trial, Netflix filed an appeal against SK Broadband and the second trial is underway.

“Netflix wants to cooperate with all Korean ISPs, and SK Broadband is included here,” Vice President Dean said. “I want to sit down and discuss with SK Broadband for co-prosperity.”

“We respect Korea’s legislation and justice,” he said, adding, “Each country has no intention of using procedures in an advantageous way to abuse something unclear.”

SK Broadband originally filed a financial application with the Korea Communications Commission to mediate negotiations on network usage fees. However, Netflix rejected this and took legal steps, sparking controversy over KCC passing.

However, he said, “There is no law on network usage fees in Korea. “It’s like that all over the world,” he said, adding, “We’ll follow the trial process well, adding.

Finally, Vice President Dean said, “I deeply sympathize with the importance of accompanying Korean creative ecosystems as well as various domestic partners,” adding, “Netflix will continue to work with ISPs and other related industrial ecosystem partners to provide the best consumer experience.”

Although Bitcoin is known, not many people even know blockchain. Although it is not receiving much attention due to Bitcoin, the most important thing in virtual assets is the blockchain, the technology on which it is based. It is time to pay more attention to how blockchain technology will change our daily lives and investment environment.

Jung Gu-tae, director of Cardo, a virtual asset custody (storage and management) company, recently appeared on the YouTube channel “Bukkumi-Ant Dreaming of Rich” specializing in Money Today Securities and stressed, “Digital assets are essential in the digital era.”

Director Chung said, “In addition to cash, various assets such as real estate, gold, and art are digitized through blockchain, and among them, there will definitely be successful cases,” adding, “This is why we should pay attention to this growing market.”

The Future of Blockchain…’Digitalize’ All Assets

Q. There are various terms such as cryptocurrency and virtual assets for various digitally implemented assets. Is there a reason why the director defined these assets as “digital assets”?

▶ Digital assets are used in a wide variety of areas, not just ‘coin’. Since there are various fields such as DPI (blockchain-based financial system), STO (securities-type token), and NFT (non-replaceable token), it should not be defined only as “currency,” but it is also difficult to define as “virtual” in that transactions are clearly taking place in the real economy. I think it’s more appropriate to describe it as a ‘digital asset’ in a sense that encompasses many different concepts.

Q. People know a lot about Bitcoin, but they often don’t know blockchain well.

The ▶ blockchain is a chain of data called ‘block’. As a result, it is very difficult to hack or falsify from outside. Now, blockchain is often only interested in ‘coin’ or technology, and in fact, it is necessary to pay more attention to how this technology can be applied and commercialized in reality than to technology itself.

Bitcoin, the representative assets that made the technology blockchain famous, and Ethereum, for example, the beginning of Bitcoin was aimed at revitalizing sign-to-sign transactions that excluded central institutions like banks. Bitcoin was created to create a payment system that allows individuals to trade with individuals. On the other hand, Ethereum has a strong characteristic of the blockchain platform. In the blockchain platform that provides Ethereum as a reward, it can be applied in various forms such as Diffie, STO, and NFT.

Q. These days, blockchain technology allows you to trade various assets such as real estate and art. How is that possible?

▶The asset securitization STO is the digitization of real assets. It was issued in the form of securities by splitting the stake in assets worth hundreds of millions and billions of won. In this way, expensive buildings or artworks can be invested in small amounts of 5,000 won to 10,000 won. With STO, all assets can be liquidated. Currently, there are companies that support real estate sales using blockchain overseas. In Korea, fintech startups are also attempting to trade real estate tokens.

Q. Recently, NFT technology has become a hot topic, so what kind of technology is it and how is it being used?

▶Non-Fungible Token (NFT) is literally an ‘irreplaceable token’. Bitcoin, for example, has the same value as the one bitcoin I have and the one bitcoin that someone else has. However, NFT has the characteristic that it is unique because each token is different.

NFT can be used in many fields. Recently, there was a case where Lee Se-dol’s 9-dan and AlphaGo’s NFT was sold for 250 million won. Hunminjeongeum Haeryeok is also sold in NFT. NFT is still in the beginning stage, and we expect it to be used in various fields such as game items and metaverse in the future.

Q. Some point out that the entire digital asset market, including Bitcoin, is a bubble.

▶ Bubble is a very relative concept. When we look back at the past over time, we can judge whether it was a bubble or not, but we don’t know if it’s a bubble in the current state. The important thing is not the present, but how this technology can be used and what value it can be given in the future. In this digital age, all assets can be digitized, and if we are confident that digital assets can be used extensively in our real lives in the future, we can invest in them.

K-pop on the metaverse
Expect platforms that will surpass SNS…We’re going to pick a new land of opportunity
Expectation of synergy by combining games and advertisements to provide personalized content for fans

1. Four idol groups come out as avatars, dance in a virtual space, take selfies with fans, and give out autographs.

2. Seven idol groups will release the music video of the choreography version for the first time in the world in a virtual space. When I buy an idol choreography, my avatar dances like an idol.

If you think of it as a novel or science fiction movie scene depicting the upcoming future, you should read this article to the end. The example above is not an imagination of the future, but a story of what has already happened. It all happened on the Metabus.

Metabus is a combination of ‘meta’, which means virtual and transcendent, and ‘universe’, which means the world, and refers to the virtual world. It was first introduced in 1992 in the novel “Snow Crash,” written by American novelist Neil Stevenson. In the novel, the characters can enter the virtual world ‘metabus’ only by borrowing a virtual body called ‘Avatar’.

The first group is BLACKPINK. In September last year, he came out as a 3D avatar on Naver’s Metabus platform Geppetto and held a fan signing event. Did people come to see an avatar that wasn’t real? As many as 46 million people visited the fan signing event as avatars during the full-day event.

Group 2 is BTS (BTS). In September last year, the music video for the choreography version of the new song “Dynamite” was released for the first time in the world in the metaverse game “Fortnite.” 2.7 million people around the world watched this.

K-pop is permeating the metaverse world in various ways. Lee Soo-man, general producer of SM Entertainment, announced his vision in June and introduced Espa, an idol group active in the metaverse world. Espa is a group that combines four real members and their four avatars. Members work with another self, Avatar. In the music video, members and avatars appear together to dance or sing. They also participate in fan meetings and concerts.

Virtual singers based on artificial intelligence (AI) technology also came out. 3D rabbit artist Apoki released his first single ‘Get It Out’ in February. The relay dance video of the song (dancing in different order for each part of the song) received 1 million views a week after it was released. YouTube subscribers reach 300,000 and TikTok followers, a short form video service, reach 2.4 million.

Why are K-pop singers on the metaverse like this? The COVID-19 incident affected. With the offline performance stage gradually decreasing due to COVID-19, people want to see the performance even online. Singers who want to be on stage and audiences who want to see them meet in the metaverse space.

Another reason is that Metabus is expected to grow into a next-generation platform that goes beyond social networking service (SNS) platforms such as YouTube, Facebook, and Twitter. K-pop singers mainly worked on the SNS platform, attracting fans from all over the world. This is why they are actively trying to preoccupy metaverse, which is expected to be a land of new opportunities in the future.

Kim Sang-kyun, an industrial engineering professor at Kangwon National University, a metaverse expert, said, “Entertainment companies are trying to use metaverse as a platform to create new content. On Metabus, K-pop singers can diversify their content. You can transform a song into a dance or a game. It can also be used as a space to communicate with fans.

Metabus is also a good container for K-pop singers’ worldviews. Kim Young-dae, a music critic, said, “K-pop idols have received responses that characters that exist in cartoons and animations seem to have been actually implemented before. They are made up of members with different looks and abilities, and are also given new personalities with mythical and fictional worldviews. In other words, the real person represents a virtual world view. The worldview embodied by K-pop idols can be expanded indefinitely without any limitations in metaverse, he said.

It can also provide personalized content to fans beyond time and space. It is impossible for BLACKPINK to sign for 46 million fans offline for 15 days, but as it is possible on Metabus. In addition, Metabus creates numerous contents and synergy such as games and advertisements, and through this, it is possible to pioneer new business models.

The metaverse target class is the MZ generation (the generation born in the early 1980s and 2000s). It is a class that mainly uses metaverse. Macroscopically, they are struggling with job shortages and are upset by soaring housing prices. They want to escape this reality and achieve vicarious satisfaction in the virtual world. Microscopically, they enjoy living in a different “sub-character” (shortened for a sub-character, which refers to a new appearance or character that is not what they usually, they enjoy living in a different way.

Wi Jung-hyun, a business professor at Chung-Ang University, said, “The so-called ‘386 generation’ and ‘X generation’ are unfamiliar with the separation of reality and virtual self, but the MJ generation tends to think that characters don’t have to be the same as themselves,” adding, “MJet generation is gaining popularity.”

How long can the popularity in the metaverse continue? There is also an opinion that it is a moment. Adam, the nation’s No. 1 cyber singer who appeared in January 1998, did so. It gained popularity by selling 200,000 albums containing the title song “Love that is not in the world,” but it did not last long. After that, I had to go down from the stage because I was forgotten by people.

So, how can I keep running on the metaverse? If you just stop with something new or novel, your popularity also stops. You need to breathe life into it to last long. In order to form a new fandom on the metaverse, the character must have its own unique charm and personality.

Producer Kim Hyung-seok, who recently introduced a metaverse-based cyber band, said, “Because it is a metaverse, it should not end with ‘fun’ and ‘wonderful’. You have to be attracted. To do this, the character must be energized. We need to find a point that is fun and touching. We need a humanities approach that explores humans, he said.

YouTube has been able to expand global fandom by K-pop singers such as BTS and Black Pink. They captivated fans around the world with their own worldview and stories in videos, not text. Attention is focusing on whether K-pop singers will continue to succeed in Metabus in the future.
