Today, the fourth industry, represented by Bitcoin and Tesla, is emerging as an important pillar of economic development in modern society. The development of ChatGPT and Bing, a search engine of Microsoft, which has recently been in the spotlight, is also an achievement in the artificial intelligence field of the fourth industry. We are also in the midst of the Fourth Industrial Revolution with the advent of smart technology, the Internet of Things, and automation. And this revolution is completely changing the way we've been working. This article is about such a quaternary industry, and I would like to find out the type of quaternary industry and furthermore the necessity of the quaternary industrial complex.
Types of Quaternary Industries
The fourth industry is having a great influence on our daily lives as it is changing the way companies operate. First of all, cutting-edge technologies such as big data, artificial intelligence, and the Internet of Things are utilized in the fourth industry, resulting in improved efficiency and rapid increase in fish quality. One of its main components is the use of cyber-physical systems (CPS). It is a computer-controlled, real-world interactive system that uses sensors and other devices to collect data and communicate with other systems for real-time control and optimization.
Big Data
The use of big data refers to a large amount of data generated by the Internet of Things and other sources. This data can be used to optimize production processes, improve product quality, and identify new business opportunities. It can also be utilized in Internet search engines to analyze the latest trends and to target products produced by analyzing various behavior patterns of people.Artificial Intelligence (AI)
Artificial intelligence (AI) has now achieved so much technological development that it is the core of the fourth industry. AI can be used to automate repetitive tasks, analyze big data, and predict based on historical data. The recently announced ChatGPT proved that it can be used in various directions such as writing articles, generating literary works, summarizing papers, and generating coding, and has emerged as one of the key technologies that will lead the fourth industry in the future.Internet of Things (IoT)
The Internet of Things (IoT) refers to a network of devices connected to the Internet, including sensors, smartphones, and other devices. As a core technology applied to smart farms, it is a technology that can automatically control the environment necessary for crops such as temperature, humidity, and amount of light. This network has the advantage of being able to monitor and control the production process in real time and supplement it in advance before problems occur.3D Printing
3D printing technology is a technology that can be manufactured layer by layer, allowing objects with complex structures that had to be made through complex assembly to be simply manufactured according to design drawings. It can be produced through various materials, and it is a highly utilized technology in the construction and construction fields as it has shown a performance of building apartments in a short time in China. This technology can also be particularly useful in industries such as aerospace, automotive, and medical care.Robotics
Finally, the use of robotics has the advantage of automating tasks, improving safety, and increasing productivity. It can also be used in conjunction with other technologies such as AI and CPS to create a fully automated production process.Necessity of the Fourth Industrial Complex
The Fourth Industrial Complex refers to a huge ecosystem where companies engaged in the aforementioned fourth industry are brought together to share information and materials between each company. For example, if you put a robot manufacturer and a research institute that studies it in one place, you have the advantage of sharing information on research, experiments, and production processes immediately. In addition, a collaboration between a company that collects big data and a company that develops artificial intelligence is also expected.In particular, this industrial complex can be expected to have additional economic effects if it is developed in an underdeveloped area. For example, if a fourth industrial complex is developed in a small local city, companies or research organizations in the fourth industry can try more various things at low cost based on infrastructure provided by local governments, and in the provinces, it can revitalize the aging population. Along with the influx of population, there is a possibility that new jobs will be created around the city, resulting in a positive virtuous cycle. This can, in turn, help promote economic growth and development and improve the quality of life of the people living in the region.
