자동차의 전기차로의 전환과 더불어 IT 기술이 접목된 자율주행기술이 빠르게 발전하고 있으며, 현대기아자동차 그룹을 비롯한 글로벌 완성차 제조사 및 애플, LG 등과 같은 IT 제조사간에 완성도 높은 자율주행차 개발에 치열한 경쟁이 이루어지고 있다. 특히 사람의 개입이 거의 없는 4단계 이상의 자율주행 기술이 적용된 자율주행차는 운전석이 없는 등 기존과는 매우 다른 실내 구조를 가질 것으로 예상되며, 사람에게 움직이는 생활공간을 제공할 것으로 기대된다. 이와 같은 자율주행차 내의 미디어 소비는 고화질 미디어를 대형 화면으로 볼 것으로 예상되며, 지상파 TV 방송은 미디어를 단방향으로 대용량 전송하는데 유리하여 자율주행차를 대상으로 미디어 서비스에 적용성이 높을 것으로 기대된다. 본 논문은 이러한 미래 자율주행차가 제공하는 움직이는 생활공간에서 TV를 시청하는 '이동TV'를 염두에 두고, 현재의 4K-UHDTV 시대 및 미래의 8K/Post-8K 시대의 비용 효과적인 지상파 TV 방송망 기술을 소개한다.

지능형 공장은 전통적인 제조분야에 정보통신기술(ICT, Information and Communication Technology)을 적용하는 것을 의미한다. 사이버-물리시스템, 사물인터넷과 같은 기반 기술들의 발전으로 지능형공장을 추구하는 스마트팩토리(smart factory)분야는 다양하고 복잡한 기능들로 인해 복잡성이 매우 크고, 문제 발생 시 이에 대응하는 것이 용이하지 않다. 따라서 본고에서는 스마트팩토리를 위한 제조설비의 고신뢰 자율컴퓨팅 기술에 대하여 살펴본다. 구체적으로는 1) 스마트팩토리를 위한 통신미들웨어 기술동향, 2) 전통적인 자율컴퓨팅 기술동향 3) 고 신뢰 스마트팩토리를 위한 자율컴퓨팅 요소기술에 대하여 설명한다.

The future society will be changed through an artificial intelligence (AI) based intelligent revolution. To prepare for the future and strengthen industrial competitiveness, countries around the world are implementing various policies and strategies to utilize AI in the manufacturing industry, which is the basis of the national economy. Manufacturing AI technology should ensure accuracy and reliability in industry and should be explainable, unlike general-purpose AI that targets human intelligence. This paper presents the future shape of the "autonomous factory" through the convergence of manufacturing and AI. In addition, it examines technological issues and research status to realize the autonomous factory during the stages of recognition, planning, execution, and control of manufacturing work.

This paper introduces the state definition and diagnostic algorithm for autonomic control of manufacturing facilities. Smart factory systems through cyber-physical systems and digital twin technology are increasing the productivity and stability of existing manufacturing plants, which has become an issue recently. A Smart factory system is one of the key technologies that make up a smart factory system, to improve productivity, enable workers to make better decisions, and to control abnormal process flows. However, performing an autonomic control process based on large number of integrated plat data requires significant advance work. Therefore, in this paper, we define an abstracted facility state for manufacturing facility autonomic control and propose an algorithm to diagnose the current state. This makes the autonomic control process simpler by autonomic control based on the facility status rather then integrated facility data.

Like the technological competition of each country around commercialization of Autonomous Vehicles(the rest is 'AV'), legalizations are also in a competition. However, in the midst of this competition, the Ethik-Kommission Automatisiertes und vernetztes Fahren of Germany has recently introduced 20 guidelines. This guideline is expected to serve as a milestone for future AV legislations. In this paper, I have formulated a new legislative proposal that will incorporate the main content presented by the Ethik-Kommission. The structure is largely divided into general rules of purpose and definition, chapter on types of AV and safety standards, registration and inspection, maintenance, licenses for AV, driver's obligations, insurance and accident responsibilities, roads and facilities, traffic system, and chapter on penalties. The commercialization of AV in Korea seems to be in a distant future, and it is possible to pretend that it is not necessary to prepare legal systems. But considering our reality, leading legislation may be necessary. In this paper, I have prepared individual legislative proposals based on the essential matters based on the criminal responsibility in case of AV car accidents. To assure the safety of AV, AV and mode of operation were defined for more clear interpretation and application of law, and basic safety standards for AV were presented. In addition, the obligation of insurance and the liability for damages were defined, and the possibility of immunity from the criminal responsibility was examined. Furthermore, I have examined the penalties for penalties such as hacking in order to secure the effectiveness of the Act. Based on these discussions, I have attempted the 'Autonomous Vehicles Act', which aims to provide a basis for new discussions to be held on the basis of various academic fields related to the operation of AV and related industries in the future. Although there may be a sense of unurgency in time, the automobile industry needs time to prepare for the regulation of the AV ahead of time. And a process of public debate is also needed for the ecosystem of healthy AV industry.

This paper describes UL 4600, a new international safety standard to ensure safety of autonomous cars. Conventional vehicular safety standards such as ISO 26262 and ISO/PAS 21448 suffer from large limitations to be applied to autonomous cars, but UL 4600 exploits new approaches to be applied to autonomous cars. Conventional standards define various technological aspects to ensure safety and require manufacturers to certify these aspects. On the contrary, UL 4600 requires manufacturer to explain and prove why autonomous cars are safe. In UL 4600, (1) under specific environments where the system is designed to operate with, (2) claims should be defined to guarantee given safety, and (3) arguments should be suggested to satisfy given goals, and (3) evidences should be presented to prove given arguments. UL 4600 is technology-neutral since it does not require specific designs nor technologies. So UL 4600 only requires manufacturers to prove given safety goals regardless of methods and technologies. Also UL 4600 admits various cases of autonomous car field operations into the standard via feedback loop. So UL 4600 effectively maneuvers various dangers unknown at the time of standard establishment.

Product liability is an important regulation factor in automotive industry. ISO 26262 international standard was established as an exemption clause of product liability. In autonomous car, product liability becomes more important, and ISO/PAS international standard was additionally established, but it can be applied to only sensing stage, which can partly make the autonomous car companies exempt the product liability but not completely. Therefore, reform of current legal system is absolutely necessary to commercialize autonomous car until a new international standard is established as a complete exemptions clause.
