Chapter 171
Arrogant democracy wasn't reoriented until the results of the Tokyo Metropolitan Assembly election became clear. The reality that the Olympics, a festival of peace, has become a tool for politics and making money has become too visible, and the world has become unpleasant. Nothing can be done cleanly, but it's too explicit. Was non-audience really only a way? It's a shame that I think it would have been possible for Japan to gather wisdom a year before the postponement was decided. In Hollywood science fiction movies, scientists are convened to look at all possible ways to contain them, but the actual convened are not an expert but doctors who treat patients with infections. From the perspective of infection prevention, it is necessary to convene experts in fields that are effective against viruses such as ozone and ultraviolet rays, as well as vaccines and therapeutic agents, and consider measures to prevent the spread of infection at airports, ports, public facilities, etc. However, in reality, people who looked like experts were gathered and used as a decoration just to justify the measures that the government would take on its own initiative. In the 1997 science fiction movie "Contact" by Carl Sagan and starring Jodie Foster, a facility set up in Hokkaido is set to bring contact with advanced organism in the universe, and the mystery of the Japanese people was expressed together with the high level of science fiction. However, when I watched it more than 20 years later, I felt something wrong. Where has Japan at the cutting edge gone? Effective use of deep-ultraviolet LEDs not only reduces the labor and alcohol usage to prevent infection in hospitals, airports, restaurants, public facilities, etc., but also reduces the infection rate in such places. In terms of introduction cost, it should have been possible to deal with it much cheaper than the labor (labor cost) and the price of alcohol. However, a year ago, I offered to offer them free of charge, despite my loud voice and alarm bell, the Olympics would begin. Inactivation of viruses by light (deep ultraviolet rays) has a long history of more than a century, and how long each virus or bacterium should be inactivated and sterilized by irradiating with a conventional ultraviolet light source UV lamp is crystal clear. There is a huge amount of data accumulated. Therefore, regarding the COVID19, the method of inactivating the envelope-type coronavirus was empirically known even before the spread of the infection. Nevertheless, I am wondering why effective infection prevention measures were not taken. The light energy Joule (J) can be expressed by the light illuminance (W) × time (S). UV-C LEDs are a sterilization light source that replaces conventional UV lamps, and while lamps contain the environmental pollutant mercury inside, they have the drawbacks of short life and cumbersome control. Japan's first state-of-the-art technology that eliminates all of these drawbacks. If this technology is used to prevent infection at the Tokyo Olympics in COVID19, and a system is built that allows visitors from all over the world to come and watch the game safely, Japan's science and technology capabilities and advanced semiconductor technology would have been appealed to the world. It should have become a good opportunity. I saw a video Russian President Vladimir Putin dive through a tunnel of ultraviolet rays at Moscow Airport, and it can be inferred that the device was installed to show off Russian technological capabilities as a countermeasure against COVID19. The president himself was in charge of showing off the technology. It's a shame Japan didn't take any action, even though we had a year to spare. For the future, we must take advantage of this bitter experience.

Defeat without fighting the COVID19
