Today, Our class was the supplementary lessons. The invited outside lecturer was talking about the attitude of the collegian who opening the Fourth Industrial Revolution. The table of contents are the ecosystem change, the counteracted innovative project, the direction of the innovative project and the attitude of the collegian. The first content is the ecosystem change. In the past, the various fields of technology was separated like the province of physics, the digitech and biology technology. But, with technology getting better, the field of technology is fused. In the province of physics, the 3D printing, robotics, new material are included. In the digitech part, Iot, Big Data, AI are included. In the biology technology part, the smart medical treatment and the genetic engineering are included. Nowadays, people fuze that the cutting edge technologies. In the aspect of that technologies outcome, we can cite an example like the cyber physical systems. The cyber physical systems is the outcome of the IoT, Big Data, smart medical treatment and the self driving vehicles. IoT means the internet of things. This technology can connect many thing. Big Data can manage the huge data. The self driving vehicles can haul away the people who is hurt. So, the cyber physical systems can help many people and makes our life comfortable. If we apply these fused cutting edge, we can develop our culture very fast. You can think about the changed future using by drone. These days, people usually use the delivery service for send the object. Using drone to the delivery service, people can get the object very comfortable. And the messenger also can delivery to customer. If these things become a reality, Our society can be more innovative society in field of the delivery. Next, we learned about the direction of the innovative project. In this part, we can apply the contents that we learned about the government 3.0. The more society develop in the communication using by IcTs, government change to citizen centered type. This type of government can influence to society. The outside lecturer said three things. 1. the private-centered competitiveness reinforcement, 2. the public service that based on the innovation and the trust. 3. the policy for gap relax. The private-centered competitiveness reinforcement caused by relax of the government regulation. Because of the relax of the government regulation, citizens can demonstrate their creativity and government apprise the citizens creative idea. The public service that based on the innovation and the trust is caused by the government failure and the system failure. So, government try to reinforce the responsive and make the institutional base. The policy for gap relax caused by the market failure. Because of the market failure, the gaps of the physical and the cultural are growing more fierce. So, government try to relax the gap. I think the government failure and the market failure are very natural phenomenon in the capitalism. In the past, the people wanted to solve the problems using the government policy and the relaxation of regulation. Or just changed the type of economical machanism. But, nowadays, people try to find the effective method for solve the problems like making the public platform. So, I think that if the technology develop and spread continually, the machanism of our society is more safety and effiective. Finally, What should collegian do for the future? We should lead the process of the attainment of goal. I think this comment similar with the professor's coment. Now, the world is changing very fast. So, we can't notice the change. But, if we were satisfied by user, that's not good for us. So, we must learned about the English, major, the tools like the AI, CAD, VR, AR, IoT, Big Data etc. Then, we can creat and lead the many field that are not yet developed.
