There are two approaches to the ethical governance of AI machines: "externalism" and "internalism". "Externalism" emphasizes the development of AI machines based on the ethical norms formulated by humans, while "internalism" highlights the self-learning ability of AI machines to form the moral consciousness of machine subjects independent of humans. By introducing the essential differences between artificial intelligence machine ethics and human ethics, this paper reveals the aesthetic implications contained in the human ethical world, that is, the beauty and aesthetic sense leading to moral consciousness cannot be simulated and stratified, and the organic life and aesthetic judgment forming moral consciousness cannot be restored. The subject moral consciousness of AI machine cannot be produced and the AI machine ethics driven by the principle of utilitarianism cannot lead to the conclusion of the meaning world of human ethics. The moral intentionality of artificial intelligence is the result of formal logic deduction, artificial intelligence machine lacks "embodiment", cannot engage in perceptual practice activities nor produce emotional consciousness, and its cognitive mode belongs to a single reductionism. Therefore, artificial intelligence machines cannot generate beauty value independently, so the "internal approach" of its governance is also an extension and expansion of the "externalism" approach.

In 1958, Shanghai Automobile Assembly Plant successfully trial-produced the first car in Shanghai, the Phoenix brand car, creating the history of car manufacturing in Shanghai. It was a breakthrough in the development of Shanghai's automobile industry in the trial production of cars. Phoenix car was a special product of a specific era, and its research and development process reflected to a certain extent how social and environmental factors play a role in the development of science and technology. Combing the development process of Phoenix car can effectively discern the historical road opened up by the Shanghai car industry in four directions: technology, style, market positioning and professional cooperation, which has an enlightening effect on summarizing the experience of the times.

In recent years, the militarization process of artificial intelligence is developing rapidly with the complex and changeable international situation. Starting from the concept of artificial intelligence and its ethical risks, this paper lists the representative ethical issues in the development of military artificial intelligence both in domestic and abroad, including identification technology and moral judgment, responsibility attribution, and disaster caused by the artificial intelligence out of control. This paper analyzes the primary causes of the ethical risks arising from the militarization of artificial intelligence, and puts forward suggestions from three aspects: ensuring the bottom line of avoiding major human disasters caused by military artificial intelligence, continuously improving the accountability gap and technical vulnerability existing in military artificial intelligence, and striving to promote the active discussion of military artificial intelligence topics in the international community,so as to provide ethical review and reference for the application of artificial intelligence to the military.

This article summarizes the unique development process of amateur radio under the joint influence of technology policies and folk technology enthusiasts during the Republic of China period, and analyzes the contradiction between the desire of enthusiasts to carry out research smoothly and the government's science and technology policies that were full of skepticism and restrictions. It showcases a historical process during which the active measures taken by enthusiasts solved conflicts. It is concluded that in some special periods, there will be different scientific views between the folk academic circles and the political circles. When contradiction occurs, there will be a complex interaction between the important folk technological enthusiast groups and the government management. The former has the ability to feed back and coordinate against policy obstacles, so as to promote scientific and technological progress. This historical process also shows that only the science and technology policy of encouraging and standardizing can promote the good development of technological enthusiasm.

The victory of Deep Blue against Kasparov in 1997 and the victory of Alpha Dog over Lee Sedol in 2016 set off the trend of artificial intelligence, however, artificial intelligence still has so far a huge gap behind humans in terms of intelligence level and range of capabilities, which hinders its development. The reason is that there is an unbridgeable boundary between human intelligence and machine intelligence. In this context, machines that rely on symbols pointing to objects can only perform formal calculations in a closed environment but cannot realize intentional calculations in an open environment like humans. Therefore, the complementary advantages of man and machine are particularly important. The current relationship between man and machine is mainly a hard function allocation, whereas the relationship between man and machine in the future digital world would more likely be a flexible division of capabilities. This paper discusses in detail the bottlenecks of artificial intelligence, the first principle of intelligence, and other issues, and gives more in-depth thinking about human-machine problem amid these problems. It is proposed that human-machine hybrid intelligence is the future development direction of artificial intelligence.

The World Federation of Scientific Workers, which was founded in 1946, is a non-governmental organization initiated by the British Association of Scientific Workers and other groups. Its members are scientific workers' groups from eastern and western countries. Since the establishment of the WFSW, China has been an important member of it, and has experienced its establishment, development and decline. This article summarized the development history of the WFSW by analyzing the relevant reports and archives of People's Daily, analyzed the development of the relationship between China and the WFSW from 1949 to 1966, and discussed in detail the interaction between China and the WFSW during this period. Then the article pointed out that the WFSW was an important international platform for China to contact western capitalist countries and publicize the political stand of New China during the period from 1949 to 1966. The Chinese government and the scientific community are the important forces to promote the development and growth of the WFSW. At the same time, participating in a series of meetings of the WFSW is a typical case in which the Chinese government serves the country's diplomacy through international activities of the scientific community. Besides, it still has certain reference significance for the development of China's diplomatic work at present.
