(Extra point) Will 3D printing change the world?

 It was surprising when the 3D printer was first released to the world. I thought there would be great development in the industrial sector. I thought it would simply help make parts. However, it is using 3D printers in various fields. In China, they built houses with 3D printing, and Boeing is said to be manufacturing airplane parts. And medical circles say that they are making artificial teeth and prosthetics.

I think 3D printing will have a big impact on the cultural and economic sectors.

The first cultural field will be 'personalization, customization'. Because you can make it with 3D printing with the design we want. We are buying mass-produced items now, but if 3D printing are developed further, it will be mass personalization. It's amazing to see customized items now, but it will become common soon.

In the second economic sector, various jobs will be created. Some people think that jobs will be reduced because machines replace people. However, 3D printers are being used in various fields and professional certificates are being developed accordingly.

Anyway, now the way to change things will be eliminated because of one part.

Introduction to our blog

This blog is a digital forum where students from Fall 2020 class in Sociology of Globalization at the Hanyang University in Korea will discuss their weekly readings and activities. For each section of the course, you are expected to post a blog post on relevant readings on our blog here and make a comment on another student's post.

What are the pros and cons of using Naver versus Google for research purposes? / Jeong hye min

 Naver and Google can access various information and articles using search engines. In particular, Google does not have a lot of information other than information search and unnecessary advertisements, and there are many papers.  On the contrary, Naver is often unsuitable because there are many advertisements on blogs and uncertain sites that are sponsored or written for manuscript fees. Google is not classified in categories, making it difficult to find the information it wants.

[Reading 2] What is the relation between culture and globalization? / Jeong hye min

  Summary   Culture and globalization have realistic limitations in terms of interacting with each other that globalization is bound to be a problem in culture as negotiations of cultural experience are used in strategies to intervene in areas such as politics, environment, economy, etc. Interesting point  Marx and Cultural Globalization Marx argued that what they saw in the progress of ultra-national capitalism as ultimately and in a positive way was the subject of historical change: 'Everywhere should be established, settled everywhere, and connected everywhere.' These are exactly the opposite situations for cultural critics today. Discussion  C ulture as a dimension of globalization
