  • How to Overcome AgingBy Lee Woo-seung Cub Reporter, Junior of Mechanical EngineeringEveryone knows that health is very important in our lives. However, many people overlook the importance of health until they lose it. Today, the average person lives to be much older than those who lived decades ago. This may sound like very good news, but the time to live with disease has increased as well. Recently, scientists have been trying to shift their focus from "Life span" extension to "Health span" extension. This means that we can increase our time on earth while being free from disease. To do this, scientists have put a lot of effort into finding the root cause of conditions that have a negative effect on our health. As a result, over the past few years, research on aging has made tremendous advances to the point where clinical trials are possible in the near future.SENESCENT CELLSThere are three issues that would be good for you to know about aging, the first is "senescent cells." Every cell has an expiration date. Cells copy chromosomes when they divide. Because of the way this works, they lose a tiny bit of DNA at the ends. This could be catastrophic, so to protect against this we have long segments of DNA called telomeres. However, this also shrinks with cell division. In some cells, after a number of divisions, the telomeres are gone and they are unable to function properly. These cells are what we call senescent cells. Senescent cells stay around and dont die. The older you get, the more of them are inside you. The problem here is that senescent cells damage surrounding tissue and cause various diseases, resulting in aging. Is there any way we can get rid of these senescent cells? Scientists have applied genetic modifications to mice that can kill aging cells on their own. Older mice without senescent cells were more active. Their hearts and kidneys worked better, and they were less prone to cancer. While most cells are designed to kill themselves when they are heavily damaged, senescent cells are not. This is because proteins in the cells command suicide, but senescent cells do not produce enough protein. In a late 2016 study, protein was injected into mice. The injection killed 80% of the senescent cells and the mice became very healthy. As a result, there are a number of new companies looking at treatments involving senescent cells.STEM CELLSThe second is the "stem cell. Stem cells are everywhere in the body and replicate to supply new cells. Stem cells are needed for an embryo that is not yet fully grown to develop properly. However, they are also necessary for the adult body to supplement new cells. In a stem cell experiment, scientists took the stem cells from a young mouse and gave them to an old mouse. As a result, the new stem cells injected into the old mouse helped the metabolism, causing the old mouse to find vitality. In another study, embryonic cells were injected directly into the heart of an old mouse. As a result, this mouse lived longer than ever before, and hair in missing areas grew anew.NADCells are made of hundreds of millions of parts. All these parts constantly need to be destroyed, cleaned up, and rebuilt. However, as we get older, the efficiency of these processes decreases and eventually do not meet the production our bodies need. One of these parts is NAD, short for nicotinamide adenine dinucleotidea, a coenzyme that plays a role in maintaining the metabolism. At age 50, we only have about half as much NAD in our bodies as we did at age 20. Decrease in NAD causes various diseases. But, NAD cant enter cells so we cant get it as a pill. Scientists noticed that other more flexible substances could enter cells and would then turn into NAD inside. In 2016, multiple trials on mice showed that they boosted the multiplication of skin, brain, and muscle stem cells. Therefore, scientists expect that NAD will serve as the first real age resistor for humans.WHAT SHOULD WE DO?As described, there are various ways to prevent aging. Killing senescent cells, using stem cells to fill the void, and controlling the metabolism of healthy cells using drugs are some of the ways scientists are researching. However, one of the biggest problems is that so far it's only been applied to mice. There is no guarantee that any of these experiments will have the same effect on humans. What this shows is that we should not expect a breakthrough any time soon, so we should continue to work to ensure successful aging.

  • Healthy BacteriaBy Jeong Hyo-bin Cub Reporter, sophomore of Chemical and Biological EngineeringRecently, much research on the intestinal microflora that has a big effect on the immune system as well as intestinal health has been published. As interest in intestinal microbial bacteria grows, related products continue to come out. Let's find out which of the many lactobacillus products to choose.lFirst generation lactobacillusThere are fermented foods, like yogurt lactobacillus.Related products : Yogurt, Yoplait, etc.Representative germ : Lactobacillus delbrue-ckii subsp. BulgaricusEffect : intestinal regulation, constipation prevention, etc.lSecond generation lactobacillusThere are products that increase the number of lactobacillus.Related products : bulgasisRepresentative germ : Lactobacillus acidophilusEffect : constipation relieflThird generation lactobacillusIt is an individual lactobacillus that has a useful effect on the human body.Related products : LACTO-FIT, GQlab, etc.Representative germ : Lactobacillus plantarumEffect : differs from fungus to fungusLactobacilli have different efficacy from fungus to fungus. The table below shows the various lactobacilli. The best way to choose a lactobacillus bacteria is to look for which one will have the correct effect on your health.How can we choose a good lactobacillus product?1. CATCH the Korean characteristic!There are lots of lactobacilli and bifidobacteria in Korean intestines. Therefore, it is recommended that you choose a product that can cause more of the same intestinal germs by eating a product that contains a lot of familiar bacterial strains.2. CHECK the amount of lactobacillus!There are products that show the number of beneficial bacteria or lactobacillus. Beneficial bacteria are various useful fungi, including lactobacillus. Therefore, it is important to select a product that has a large amount of lactobacillus, not just a product that has a large number of beneficial bacteria.3. CHECK Myself!Synbiotics contain not only lactobacillus for us, but also feed the lactobacillus that reside in our intestines, which makes the environment of our intestines more comfortable. Therefore, in the case of immunosuppressive patients or people with diabetes, the product should be selected through expert consultation.Determine what effect you need, what your condition is, and choose the right lactobacillus. If you do so, not only will your intestinal health improve, but your overall health and immune system will also. There are many kinds of Lactobacilli that have many difficult names, but with a short amount of time and attention, you can find the synbiotic product that you need. Let's get healthy with close attention!

  • Big 4 MusicalsBy Park Ji-hyeon Reporter, Junior of English Language and LiteratureIn the early 2000s, the Korean musical stage began to change. This is because the copyright and production system of overseas musicals were brought into Korea, recreated, and performed. The iconic British musical Phantom of the Opera was performed in Seoul for about seven months and attracted hundreds of thousands of people. This led to a musical fever in Korea. Lets learn about the Big 4, the most famous musicals in the world.CatsCats shows the cats feast against the background of a Jellicle Ball to go to heaven. T.S Eliots poetry inspired the plays festival of Jellicle Cats, which is held once a year. The biggest feature of Cats is that 30 actors are dressed up as cats while singing and dancing. This musical captivated audiences with its brilliant dances and music. So far, it has been translated into more than 20 languages in 30 countries around the world.Les MisrablesThe musical Les Misrables was first performed in London in 1985, based on Victor Hugos novel Les Misrables. Les Misrables is about the life of Jean Valjean, a young man who had been convicted for 19 years for stealing bread. It was designed to show the revolutionary spirit of the Napoleonic times and the humanity of the poor. The musical Les Misrables has been the longest-running London musical since 1985. So far, it has been performed in 21 languages in 42 countries around the world.The Phantom of the OperaThe Phantom of the Opera is also based on a French novel. This is a sad love story about a gentleman who has a celestial voice but is covered in a mask by his ugly appearance and his love for the beautiful Christine. The Phantom of the Opera was first performed in London in 1986 and has been watched by more than 130,000,000 people so far. It has been performed in 21 languages in 42 countries around the world. It is considered a musical masterpiece with the longest-running performances on Broadway.Miss SaigonThe musical Miss Saigon is a relatively recent musical compared to the previous ones. It was created as a motif of Giacomo Puccini's Madama Butterfly and a photograph that spread immediately after the Vietnam War. This is the story of a Vietnamese woman who raised her children and dreamed of seeing the U.S. pilot she was engaged to during the Vietnam War. It was loved for its music, 3D technology, helicopters and other stage devices that perfectly reproduced the drama.Why are these four musicals called the Big 4? These four musicals have something in common. They premiered in London in the 1980s, and then progressed to Broadway and spread around the world. Broadway, the home of musicals, has been in a long recession since the 1960s. At that time, Cameron Mackintosh created a series of musicals that were much like a Hollywood movie. Musicals from Broadway and the West End of London were exported to Asia, Europe, and South America in the form of touring performances with Mackintoshs global marketing. The Big 4 musicals came out around this time. In the 1980s, western media crowned these musicals as The Big 4, that promoted the globalization of musicals. These four works are distinctly different from traditional Broadway musicals. They created stories with a universal theme that transcended time and space, and the music was arranged with an exquisite mix of pop and classical music. The most obvious change was a huge scene that utilized cutting-edge technology in Phantom of the Opera in which the chandelier dropped over the audiences head, and a realistic helicopter that hovered on stage in Miss Saigon. The Big 4 musicals were enjoyed by all people of ages, regardless of country.Recently, various musicals, such as Jekyll rables, The Phantom of the Opera and Cats, which are still running extraordinarily successfully around the world.
