1. The meaning of appropriate technology (20215 최석진)

# data[].attributes.body
Appropriate technology is a technology that is in small scale. There are a lot  conditions for a technology to become an appropriate technology. The technology should be able to be used by everyone and should not be centralized. Also, the technology should be used to solve technological problems around the world by providing sustainable assets. Appropriate technology is usually used to help people that can't afford resources like energy and aren't well educated, appropriate technology should be user friendly. By being user friendly, uneducated natives could use it easily. Appropriate technology was originally called intermediate technology.

1. By Whom and When It Was Invented (20231 정채람)
DryBath was invented in 2011 by Ludwick Marishane.

2. How it got started (20225 왕은조)
‘Dry bath’ was invented by an ordinary boy in Republic of South Africa. His name was Ludwick Marishane. Ludwick was just too lazy to wash, so he looked for a way to wash without water. One day while he was looking for a way, he came across stories about people who couldn’t wash because of no water. They couldn’t wash and were losing their sight every year. From that day on, Ludwick researched how to wash without water and invented ‘Drybath’ after 4 years.

3. How it operates (20231 정채람)
DryBath is a bath-substituting gel, designed to replace the need for soap, water and skin lotion. It works just like the hand sanitizer we used. However, unlike hand sanitizer, it can be applied the entire body and has a moisturizing effect. How to use is simple, just apply 'DryBath' and wipe it off with a towel. Using this has the same effect as taking a shower.

1. By whom and when was it made
-  The Soccket ball was made in 2008 by Havard University students.

2. How it got started
- They made it known that children from underdeveloped countries, including Brazil, Columbia,  like soccer because of difficult circumstances.

3. How it operates
Soccket ball produces energy by turning the energy of motion into electricity. Inside the ball, there is a gear. If someone kicks the ball, the gear inside spins and produces energy. The energy produced for 30 minutes can be used for three hours.

The Soccket ball is made to help people and I think helping people with joy is a mind blowing idea. However, the product has a few major problems.

The First problem is that it can't be touched to water. Although the Soccket ball is a ball, at the end of the day, it is a mechanical device. If a few drops of water end up being inside the ball it might bring fatal damage to the mechanical system and make the Soccket ball useless for charging.  The second problem of the ball is that it can only light a small LED light for 3 hours if kicked for 30 minutes. This may look fair. However, this is when the device the ball is activating is a LED lamp. If people try to activate something brighter or bigger than an LED lamp ( such as a simple light bulb or an oscillating fan ) it might not work because of lack of electricity.

This ball has a few major problems. However, like many other ancestors of appropriate technology, I believe this product will become better and better. Besides, nothing is perfect from the beginning let alone ever.

The Reason I Think the Technology Is Important

In my opinion, DryBath is a quite good invention that helps people.
First of all, the advantage of this invention is that it makes people spend more time on valuable things  instead of wasting time in the shower.
All you need is to apply the gel on your body and just rub it off using your hands.
From a social point of view, it can help many countries which is suffering from scarcity of water.
Nowadays there are almost two billion people in the world without adequate access to water and sanitation.
Designed to replace the need for water, this invention can help people to lower the excessive water use and provide cheap personal hygiene alternatives to the poor. (20231 정채람)

In my opinion, Soccket ball is really important invention to people in undeveloped country.
Many people in underdeveloped country doesn't have a energy.
So, they should use fire when they need to watch out at the night.
I'm sure that there will be a person who says it is not bad to use fire.
But if they use fire, It will be uncomfortable to make fire every time.
Also, the small fire that they made for watch out, can get bigger and make someone dead.
However. if they have energy, they can watch out without fire at night.
Also, when they need help, they can call anyone who has an ability to get out in that situation.
Of course, there are lots of way to get energy in undeveloped country.
Many people invented wonderful invention to them but, I will be happy when energy from me makes many people safe on big fire if I'm a child in underdeveloped country.
