After watching the video Can you transplant a head to another body? After that, I had new thoughts about the future of human medicine and ethical issues. The video delves into the scientific possibilities, technical challenges, and ethical controversies of head transplantation.


Head transplantation faces huge technical difficulties, including the connection of spinal nerves, immune rejection, and maintaining blood supply to the brain. These technical problems need to be broken through before head transplantation is feasible. The video introduces existing relevant medical experiments and research, such as partially successful head transplant experiments in animals. These studies provide the basis for future head transplants, but are still a long way from being applied to humans. Head transplantation is not only a technical issue, but also an ethical one. The video mentions that issues such as identity, quality of life and social acceptance that a head transplant may bring need to be discussed in depth. These ethical issues are even more complex and important than the technical ones. The video looks back at the history of head transplantation, including some of the early experiments and the efforts of scientists. These historical contexts help us understand the progress and direction of current research.

Through this video, I gained a more complete understanding of the science and ethics of head transplantation. Head transplantation is not only a medical and technical challenge, but also involves profound ethical issues and social implications. Although head transplantation is still in the experimental stage, with the advancement of science and technology, it is possible to make breakthroughs in this field in the future. However, any technological progress needs to be ethically based, ensuring that the fundamental rights and dignity of human beings are respected and upheld while scientific development is pursued.

All in all, this video not only broadens my knowledge horizon, but also makes me deeply reflect on the relationship between scientific progress and ethics. This reflection is particularly important for those engaged in scientific research and medical practice in the future.

Introduction to our blog

This blog is a digital forum where students from the Spring 2024 class in Everyday Life at 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. An ideal commentary should be about 800 words, divided into three clearly labeled sections in which you: 1) summarize in your own words of materials you read; 2) mention any new, interesting, or unusual items learned; 3) identify at least one question, concern, or discussion angle that is either problematic in some respect or could have been elaborated more. This question is likely to be incorporated into our class discussions. You are allowed to quote an interesting passage from the text(s) you've read, but the quotes will not count toward any length requirements. The blog’s deadline is always: Sunday, midnight, of the week the question is posted. Remember: in

Using Goffman's Theory to Analyze Pleasantville

 In Pleasantville, there is no basketball that cannot be pitched, which is a setting. When David told Skip that his sister might not date him, Skip didn't score a goal. This was Skip's Manner, expressing his shock and also indicating that Pleasantville was starting to change. In Pleasantville, the world is black and white, with houses, cars, streets, and trees. This is a setting that lets the audience know that this is not a real world. Team consolidation Between team members, during the performance but not ending it. Secret communication reviewing backstage things during the performance David and his sister Jennifer are part of the same team, and they have a conversation. David hopes Jennifer can abide by Pleasantville's rules, otherwise they won't be able to return to their original world. This is a kind of team conflict,

week 2 classroom questions

w.2 1. I think the team is that everyone has a different division of labor, not only the individual work results, but also the team's results.Everyone in a team has complementary skills to solve problems together to achieve common goals. It's like a family party where the mother will be responsible for shopping, the sister will be responsible for cooking, and the brother will be responsible for setting up the scene. 2. Why do Koreans prefer black clothes?First, I think black clothes are more resistant to dirt than other colors.Second, black is a classic and colorful color, do not choose the body, do not choose the skin color, suitable for various occasions.Third, black clothes can show simplicity and luxury, and can show different styles with various clothing styles, especially black coats and down jackets, which can not only blend into the winter atmosphere of Korea, but also reveal luxury and urbanity in simplicity.
