I learned about them in life science class, so I’ve become interested this passage. And this made me explore more examples of adaptation and evolution.

Have you ever heard about “Natural selection”? In Natural selection, Darwin suggested that among the individuals with diverse variation, the one who is best adapted to the environment is selected and leaves offspring. One example of natural selection is that in Africa, where malaria occurs frequently, a number of people with sickle-cell anemia(낫 모양 적혈구 빈혈증) relatively high. Thus, through this repeated natural selection, evolution occurs in a way that one build better character.

The Appearance and Evolution of Antibiotic-Resistant(항생제 내성 세균) can be explained by this Natural selection. At first, every germ in group has no resistance to antibiotics. But one day, mutations(돌연변이) led to the appearance of antibiotic-resistant bacteria, and when antibiotics were used, resistant bacteria more survived and left more offspring than non-resistant bacteria. As a result, a number of Antibiotic resistant in the group increases

Like this, adaptation and evolution have taken place through natural selection. I wonder what will be selected to survive in the future. This time, I showed about more examples about adaptation with Natural selection; sickle cell anemia and antibiotic resistant. I hope you understand them well. Thank you for listening

초안: (서론)Hello everyone, today i'll talk about the importance of satisfaction in diplomacy based on the text I selected. Are you guys more likely to satisfy on situations you're in, or the opposite? A writer of this passage suggest we should be grateful for our present no matter what we eager in our mind. 

(본론)I agree on this context. In my opinion, this attitude suits on diplomacy between nations not only on individuals. Of course every country pursue their own benefit and development. But if they become too greedy only for their own gain, relation between the countries will break. That's where the war occurs. They will steal from each other, don't care about harms they give to the opponent. 

(결론)They might obtain what they wanted by the violent activity, but I'm sure that's not the only way. We know a country needs certain degree of aspiration of their development. However we must also remember to appreciate and to make effort on preserving things our country already have.

  Have you ever seen a patient in an intensive care unit surrounded by various medical machines? We can often see it in hospitals. A patient can be a recoverable, but be a person who has a slim chance of survival and has only suffered continuously. According to National Statistical Office, 77 percent of people's deaths are medical institutions. This result is caused by two institutional reasons. First, guardian’s medical obsession is increased by low copay, amount paid by consumers after health insurance is applied. Second, because of the law, the medical staff must use a ventilator to the patient who don’t have recoverableness. Obsession with medical care can cause meaningless life-sustaining treatment. Sad to say, although there is a hospice, in which by hospitalizing patients close to death they can get comfort, this will only prolong the suffering time of patients.

  Likewise, medical development can prolong patients' suffering time. I’d like to emphasize that the practice of medicine is a double-edged sword. So I think we should be careful in medical practice. Thank you for listening.

   

Do you know that the age group of people who take the smartphone in the first time is getting lower? If parents give the smartphone to children, they can handle the work easily so the percentage of children under the age of 3 who take the smartphone is increasing. If children are exposed to the digital devices, the problems happen in frontal cortex. The function of it includes the ability to resist impulses and control emotions.

To this reason if it doesn’t mature healthy, lack of attention and ADHD will arise.

Dr.Walter Mischel of Stanford University in the U.S. conducted marshmallow experiment on infants from the late 1960s. The marshamllow experiment can identify the children’s patience by giving them marshmallow and cheking the time they don’t eat it. And he followed up on children after decade. The surprising results of this experiment were that children who had longer patience than those who didn't are more healthy and take the high scores. According to this, We can check the function of frontal cortex.

   

Finally I’ll explain that we can’t expect the healthy development of frontal cortex to children who are getting addicted to smartphone and gradually losing their patience. Hence I’d like to emphasize that you express and controll your emotions rather than doing smartphones often. Thank you for listening.

   

Im going to talk about wheter having more options is a good thing.Before reading this article, I was wishing I had more options.

However, there may be a price to pay in terms of happiness. As an example in this article, there was a person with 24 choices and 6 choices.  I Expected people with 24 options to be happy.  But, people with 6 options were happier.  The more choices I had, the more I worried about what to choose, and the more I feared that I was making the wrong choice. I felt depressed and burdened when there were many choices. I think the reason people want to have so many choices is because of greed.

Another example is the need to have fewer menus in the food program and I've seen good when guests choose. At this time, guests feel comfort and satisfaction. Certainly, It also has the advantage of having many options. But it can have a bad effect on us. Thank you.

Hello, everyone.  I chose Xistory N11. The writing compares the appearance and disappearance of changes to the movement of the river and argues that they accept change like a flowing river. Because I'm interested in economics, I'd like to introduce to you today that the arguments in this paper can also be applied to the economy. 

Economic change is caused by various factors such as climate problems, COVID-19, and war. In particular, COVID-19, which has continued since 2020, has caused Korea's economic growth rate to fall. I think the economic situation would have been much more depressed than it is now if we had resisted the change in the economic structure caused by COVID-19. But I think we've made a better economy by accepting and dealing with it.


So I've applied the argument of question N11 to the economy. I think it's really important to accept and respond naturally rather than fear losing something due to change. This can be applied in many ways in addition to our lives and economies, so we should always keep that in mind. Thank you for having listened to me so far.

Why don't we look for other words that have many meanings together? Don't you think it'll be fun? Then thank you for listening to my presentation so far.
