1.Appropriate technology
Words that refer to technologies or their products made in consideration of the infrastructure level of the community. It is one of the solutions to the "technology delay," a phenomenon in which inconsistency occurs due to the inability to keep up with the rate of change in non-material culture in the process of cultural change.

2. Life straw's real life example
(1) By whom and when it was invented

- The purified straw "Life Straw" is a representative example of appropriate technology designed to solve drinking water problems in developing countries. Lifestraw was developed by a company called VESTERGAARD 베스터가드 located in Switzerland. The company started its business as a natural fabrication in Denmark in 1957, and Michel Vestergard 미켈 베스터가드, the grandson of the founder, took charge of the company and began developing appropriate technologies in earnest. Michel was in business in Nigeria before the 1993 riot, and his experience at that time found that there were more children in Africa who died from diseases caused by contaminated water than children who were shot and killed. Lifestraw is said to have been developed in 2005 after about 10 years of research.

- I think this Technology is very important in poor countries or developing countries because they can use it without a lot money and it contains the things they need to use there. So I hope to develop this Technology more than now.

- As a Korean, I think I don't need their technologies, but if I think of poor countries around the world, I think this technology is very important because water is the most essential thing to livings, and this technology can help people live a cleaner life.

- I think this invention is great one because it can help many people in poor countries. But I think there are some hard progress when poor people use this invention in real, such as cost. So if I have a chance, I would like to request the company to lower the price.

- I think this 'Lifestraw' is lifesaving invention to many poor countries. But I think there is a one thing have to change that the inventor of this lifestraw lower the price. This is expensive to poor people so they cannot buy it freely. However, there is no doubt this invention is amazing stuff.
