Alternative medicine. This was the agenda of NOVA lesson yesterday. We discuss whether is recommended alternative medicine or conventional medicine. Other students who were electronic engineers had an opinion that alternative medicine should be recommended because they were suspicious about conventional medicine. I insisted remedy lack of evidence should not be recommended. At first they disagreed my opinion, but after my introduction I’m medical related worker they didn’t deny. This issue is so controversial that we could not reach good conclusion. But we found a lot of worth ideas. It would be important that we should not be obsessed our own opinion , listen to others and discuss frankly to discover better ideas. That is the best way fitting in WEB 2.0 era.
