W6.Municipal wastewater treatment energy management/Lim Ji Won

Municipal wastewater treatment energy management aims to recover energy consumed and make it sustainable because wastewater treatment is the most energy-intensive and highly dependent on fossil fuel-based energy resources.

Wastewater contains energy, nutrients and other organic and inorganic resources that can be successfully recovered and used in a broad range of applications. Energy is a very important resource because it can be recovered by biogas and heat, and nutrients can be used for fertilizer. In addition, wastewater from wastewater treatment plants can be reused in agriculture and landscaping, and is a very important resource in countries with long droughts.

In fact, it is said that the wastewater treatment plant that increased efficiency has succeeded in reducing the energy demand by 50% without affecting the wastewater treatment performance.

However, there are several barriers to the creation of renewable energy in wastewater facilities.
It is difficult to generalize because it requires high initial investment cost and customized solution according to the difference between each factory.

Due to the disadvantages mentioned above, there was a characteristic that it was difficult to introduce it in developing countries that required a lot of wastewater treatment facilities. If so, do you think developed countries should provide financial support to these developing countries to create wastewater facilities that allow them to recycle energy from wastewater treatment plants?

Millennium Development Goals, or MDGs, sought 191 U.N. member states and more than 22 international organizations to achieve their goals by 2015. MDGs have promoted the development of the international community.

However, it has been criticized for lack of legitimacy, neglect of female inequality in employment, and uneven achievement rate, but it has contributed a lot to many equal development. Interesting point I knew that international politics was carried out in a complex and selfish atmosphere. However, upon encountering the MDGs, I learned that the international community is making great efforts to ensure human rights. Among the MDG criticisms, criticism of women's inequality was interesting. The phenomenon of female ineq...

What is meant by that? / Lee hayoung

Q. Society is not determined by technology, nor is technology determined by society. Both emerge as two sides of the sociotechnical coin. What is meant by that? A. So to begin with, I think that society and technology are the relationships that influence each other, the concepts that one cannot include or dominate. There is technology in society, and technology exists because there is society. I think it's an inseparable relationship, so I think it can be expressed in both sides of a coin.

W10. Human_rights / Lee Se Hyun

Summary Human rights are the basic right to live as a person. This is an absolute domain. Applicable regardless of ethnicity, gender, age, or location and guaranteed by international law. Human rights have been modified and established over a long period of time. From ancient times to the post-World War II international human rights treaties, various changes and considerations continued. Since the 1966 Human Rights Treaty, the concept of human rights has been established and human rights are guaranteed at the international level through the UN, an international organization. Also, various efforts are made to ensure human rights in the community. Human rights organizations are established in continental units such as Africa, America, Asia, and Europe, to strive for the self-reliance of the vulnerable classes and countries. Human beings have studied human rights for a long time. Thus, the theory of human rights exists, and there are various views on human rights. Interesting point ...
