[Phy] Sudden Acceleration-Airbag Safety

Title: Explain the way to reduce child fatality rate caused by airbag.

When people think about vehicle safety devices, there are two things coming out easily. Seat belts and airbags. But, one of them, airbag may hurt or kill the life when it is used improperly. Also, it affects differently on children and adults. Therefore, children and adults should use safety devices differently, but not many know it. When the airbag is used without seat belt, it increases the fatality rate. However, many people do not know it properly. Also, this issue was always talked about, but no actual actions were done. Therefore, I want to explain the danger of airbag for children, correct way to use airbag as ‘safety device’, and the solution that science can do through this one world essay.

Republic of Korea is a big energy importer and consumer. Dependence on imported energy is over 95 percent. It is a world’s 10th biggest energy consumer, but has very limited natural sources. However, it is researching for energy that it can produce and consume independently, such as reusable energy. It also produces energy by nuclear fusion, but the source, Uranium is imported.

[Bio] Down Syndrome

Down syndrome, which is also called Trisomy 21, is quite well-known disability, but not many people knows what exactly it is. Down syndrome is the most common chromosome abnormality in humans. There are three types of the cause of down syndrome. First, most commonly, 95 percent is by nondisjunction. This means that cells did not equally divide the genetic information. This leads a sperm or an egg has one more 21 chromosomes. When this sperm or egg combines with the normal sperm or egg, with 23 chromosomes, finally it makes 47 chromosomes, 3 copies of 21 chromosome. This is what people usually calls, Trisomy 21 (2011). 4% of down syndrome occurs by translocation, which happens when 2 chromosomes combined together which seems like 1. By that, cell makes one more extra chromosome to fill 2. There is right number of chromosomes, but actually, there is one more chromosome (2011). Both ways, there are more chromosomes than it has to be. By that, it occurs disorders and structural anomaly in whole range of body where chromosome 21 exists.

Because down syndrome is caused by the disorder of the chromosome, it affects on every part of physical appearance, physical development and medical conditions. They usually have decreased muscle tone at birth, wide hands with short fingers, flatten noses and others, which makes it is quite easy to find out people who have down syndrome. But not only the appearance, they have impulsive behavior, slow learning, eye and hearing problem, and much more. (Zieve, 2012) There is no treatment for down syndrome for now...
