In the future, various products are created in various fields using artificial intelligence. In this age, it is a very important problem to know the operation principle of artificial intelligence learning method and to use it correctly. This paper introduces artificial intelligence learning methods that have been known so far. Learning of artificial intelligence is based on the fixed point iteration method of mathematics. The GD(Gradient Descent) method, which adjusts the convergence speed based on the fixed point iteration method, the Momentum method to summate the amount of gradient, and finally, the Adam method that mixed these methods. This paper describes the advantages and disadvantages of each method. In particularly, the Adam method having adaptivity controls learning ability of machine learning. And we analyze how these methods affect digital signals. The changes in the learning process of digital signals are the basis of accurate application and accurate judgment in the future work and research using artificial intelligence.

Recently, Chat GPT artificial intelligence (AI) is of keen interest to all governments, companies, and military sectors around the world. In the existing era of literacy AI, it has entered an era in which communication with humans is possible with generative AI that creates words, writings, and pictures. Due to the complexity of the current laws and ordinances issued during the recent national crisis in Korea and the ambiguity of the timing of application of laws and ordinances, the golden time of situational measures was often missed. For these reasons, it was not able to respond properly to every major disaster and military conflict with North Korea. Therefore, the purpose of this study was to revise the National Crisis Management Basic Act, which can act as a national tower in the event of a national crisis, and to promote artificial intelligence governance by linking artificial intelligence technology with the civil, government, military, and police.

본 연구는 '인공지능이 그린 그림은 예술적 가치가 있는가?' '인공지능을 활용한 21세기의 현시대 예술은 무엇인가?' '어떻게 실현되는가?'라는 실천적 질문에서 출발하였다. 4차 산업혁명은 초실감(Hyper-Reality), 초지능(Hyper-Intellect), 초연결(Hyper-connect)로 '초(Hyper)의 시대'를 예고하고 있다. 이 혁명은 현시대 예술가에게 현실과 가상을 분간할 수 없는 혼합현실환경, 예술의 창작활동에 훌륭한 조수로서 역할을 할 수 있는 인공지능, 예술적 경험을 가상과 현실을 넘나들며, 언제 어디서나 즉각적으로 체험할 수 있는 기술을 제공한다. 실천적 질문에 대한 해답을 찾기 위하여 주관기관 홍익대학교, 참여기관 서울미디어대학원대학교, (주)브이알애드가 2018년 5월부터 2019년 12월까지 2년간 진행한 한국콘텐츠진흥원 문화기술 연구개발 지원사업 '인공지능 기반 창작 아틀리에 발굴 및 구축 기술 개발 프로젝트'를 통하여 인공지능 엔진(stNET, vidNET, hdtNET, omniNET)을 개발하였고 예술가와 4번의 전시를 통하여 성능 및 가치를 실증하였다. 인공지능은 그동안의 예술적 장르와는 차별화된 특이점을 가지고 있으며 응용 범위 또한 다양하다. 현시대 예술가에게 새로운 장르 개척의 훌륭한 조수로서 역할이 가능하다는 것이다. 그동안 현대 예술의 조형과 개념 미술에 한정적 메시지를 넘어, 인공지능기반 초 실감, 실 시간, 직관적 인터랙션을 통하여 직접적 예술 경험을 체험할 수 있다는 점에서, 현시대의 예술가에게 초 경험 예술(Hyper-Experience Art)의 시작인 동시에 새로운 장르 개척의 단초가 제공된다.

The purpose of this study was to investigate the expectation toward medical artificial intelligence(AI) of students in majoring health, and to utilize it as a basic data for widespread use of medical AI for 500 students majoring in health science at Cheonan city. The awareness of AI was 18.6%, the reliability of AI was 24.8%, and agreement to use of medical AI was 38%. Also, the higher the awareness and reliability of AI were, the higher the expectation of AI was. As a result, education on medical AI in the major field should be a cornerstone for the development of an effective healthcare environment utilizing medical AI by raising awareness, reliability and expectation of AI.

This study aimed to interpreting the view of current media by artificial intelligence(AI) with the case of a TV show Person of Interest, which was broadcasted until 2016 in US. In this study, we first attempted to find how AI reflects the three laws of robotics, which often appear in Science Fictions. In addition, we paid attention to how the society looks according to the change of the manipulator of the AI, and as a result we derived the distinguishes of the show from other content dealing with robots or AI in terms of narrative. Through this study, we classified the messages in accordance of AI into three categories- importance of data sovereignty, potential of intelligence explosion, and blind faith in high technology. This study suggested that the show emphasizes the consciousness and attitude that should be possessed as a citizen who meets the era of AI prior to raising issue of 'what artificial intelligence is should be developed for our convenience?'

The artificial intelligence (AI) is a technology that will lead the future connective and intelligent era by combining with almost all industries in manufacturing and service industry. Although Korea is one of the world's leading artificial intelligence group with the United States, Japan, and Germany, but its competitiveness in terms of artificial intelligence patent is relatively low compared to others. Therefore, it is necessary to carry out quantitative analysis of artificial intelligence patents in various aspects in order to examine national competitiveness, major industries and future development directions in artificial intelligence technology. In this study, we use the IPC technology classification code to estimate the overall life cycle and the speed of development of the artificial intelligence technology. We collected patents related to artificial intelligence from 2008 to 2018, and analyze patent trends through one-dimensional statistical analysis, two-dimensional statistical analysis and network analysis. We expect that the technological trends of the artificial intelligence industry discovered from this study will be exploited to the strategies of the artificial intelligence technology and the policy making of the government.
