4차 산업혁명이란 인공 지능(AI)과 사물 인터넷(IoT), 빅 데이터 (Big Data), 클라우드 컴퓨팅 그리고 모바일 등 지능정보통신기술이 기존의 경제와 산업, 사회 전반에 융합되어 혁신적인 변화가 만들어지 는 차세대 산업혁명을 말한다. 4차 산업혁명이 다른 점이 있다면 변화의 속도와 융합이다. 과거의 기술이 사람들이 충분히 적응할 수 있을 만큼 변화의 속도가 느렸다면, 3차 산업혁명 이후로의 기술의 변화는 사람이 기술에 적응하기 전에 새로운 기술이 덮쳐오는 시대가 되었다. 4차 산업혁명은 여기에 더하여 인공지능이 다양한 전문성과 결합하면 서 예상할 수 없는 형태로 진화할 것이다. 그러나 이것도 하나님의 주도하에 이루어지는 것이며, 세상 끝 날까지 선교를 주도하시는 분은 하나님이시다. 지금까지의 산업혁명은 인류가 오랫동안 유지해왔던 농경사회에서 산업사회로 다시 정보사회로 사회와 문화를 변혁시켰으 며, 선교도 이러한 변화의 상황 속에서 새로운 방법을 개발하고 선교의 영역을 확장시켰다. 그러므로 우리는 도래한 4차 산업혁명의 시대에도 선교의 본질을 잘 유지하면서 이 시대와 소통하는 선교의 방법을 고민하 고 전략을 개발해야 할 필요가 있다.

1,2,3차 산업혁명은 ‘제조업을 중심으로 한 생산혁명’이라고 한다면, 4차 산업혁명은 첨단 통신기술을 기반으로 ‘전 산업분야에 걸쳐 일어나는 소비혁명’이라고 할 수 있다. 지능정보기술이 확산하며 생산과 소비의 전 과정이 지능화되고 긴밀하게 상호작용하는 혁명적 변화를 가리킨다고 할 수 있다. 사물인터넷, 빅데이터, 인공지능 등의 지능정보기술이 스마트한 초연결 플랫폼을 형성함에 따라, 생산과 소비의 전 과정이 실시간으로 융합하는 시대가 열리고 있다. 생산자는 소비자의 요구를 실시간으로 반영하여 재고 없이 생산하고, 소비자는 원하는 제품과 서비스를 적기에 제공받을 수 있게 될 것이다. 매년 세계 식량의 1/3이 폐기되어 1.3 조억 달러(2015년)의 손실이 추정되는 식품산업도 4차 산업혁명과 연계해, ICT를 기반으로 제조, 유통, 소비 전 과정에서의 신선도, 온도, 습도 등에 대한 정보를 Retailer나 소비자에게 스마트패키징을 통해 식품 안전과 손실 저감을 획기적으로 줄여감으로써 미래 스마트컨슈밍 산업을 선도할 것으로 기대하고 있다. 인쇄전자와 Nano 기술의 발전은 감각센서, 전자태그, 기능성 복합소재 형태로 스마트패키징의 기술구현을 이루고 있다. 이러한 스마트패키징은 식품의 품질유지와 제품수명 연장을 위한 능동형패키징과 식품의 안정성과 제품정보를 제공하는 지능형패키징으로 구분되며, 친환경패키징와 더불어 4차 산업혁명 시대에 식품포장 산업의 새로운 전개를 해 나갈 것으로 기대된다.

World is now shifting from the industrial and information society to the 4th Industrial Revolution in its structure, and new products and services appear in various sectors. The 4th Industrial Revolution changes the entire daily lives in more convenient, safer, and more effective forms. There will be many changes in food industries with combination between intelligent information technologies such as IoT, big data, AI and new technologies such as 3D printing, robotics, and nano-technology, developing more intelligent ones. Intelligent IoT is one of four main basic industries for sustainable growth with future driving force in Korea. Since 2010, food smart distribution researches combining food technologies and ICT have been conducted in Korea, and core original technologies including quality management sensor, intelligent food distribution environment control system, smart warehouse, real-time quality monitoring, etc. Food smart distribution technology is a system converging ICT including sensor tag, sensor network, and LBS and food technologies for safe management of history, quality, and distribution, and it will be applied to food distribution industries, developing the domestic food distribution industries to the world-class level. Recently, IoT has been increasingly introduced into food industries, and development of new convergence technologies and adjustment to technological changes are required, and it is necessary to establish strategies for how to introduce food system based on IoT. As a result of the analysis of frequency of keywords o technological trends by applying text-mining technologies into tremendous amount of unstructured data created by newly convergence technologies between food and the Fourth Industrial Revolution, there are eight main keywords including IoT, smart sensor, artificial intelligence(AI), multi-tasking, automatic cognition/discernment, quality management, simplification of distribution, an customer-friendly. It is necessary to make national strategies for R&D. In case of Korea, ICT is the world class, and if it is applied to food industries, it will be available to develop new world-class business models.

The 4th Industry Revolution was advocated by Klaud Schwab who is founder of World Economic Forum at the Davos Forum in 2016, and there are big differences on ICT based 4th Industry revolution in the aspects of speed, scope and impact compared with the 3rd Industry revolution. Creating new industries and values through technology such as internet of things, cloud, big data, and artificial intelligence are included in the meaning of The 4th industry revolution. In this article, the direction of change to water technology in response to the 4th Industry revolution is surveyed. 4G Water Infra should minimize environmental impact under the consideration of sustainable development and advanced technologies. To solve the existing water infra problems, it is common and fundamental that the intake water from nature can be regarded as borrowed from nature and it should be returned to natural state with improved water quality. Government, academic organizations and industries should prepare and collaborate together in order to help our country with outstanding capabilities in infrastructure construction and ICT to lead the 4G water technology development.

Advances in information technology, communication and network technology are radically facilitating digital convergences as the integration of human, equipment, and space in the current industry 4.0 era. In industry 4.0 environment, the vast amount of information with networked computing technology can be simultaneously accessible even in limited physical space. Two main benefit points out of these information are the convenience and efficiency in their online transactions either buying things online or selling online. Even though there exist so many benefits that information technology can create for the people doing business over the internet there is a critical problem to be answered. In spite of many such advantages, however, online transactions have many dysfunctions such as personal information leakage, account hacking, and cybercrime. Without preparing the appropriate protection methods or schema people reluctantly use the transaction or would find some other partners with enhanced information security environment. In this paper we suggested a novel selection criteria that can be used to evaluate the reliable means of authentication against the expected risks under on-going IoT based environment. Our selection criteria consists of 4 steps. The first step is services and risk identification step. The second step is evaluation of risk occurrence step. The third step includes the evaluation of the extent of damage. And the final step is the assessment of the level of risk. With the help of the above 4 step-approach people can systematically identify potential risks hiding in the online transactions and effectively avoid by taking appropriate counter actions

The Fourth Industrial Revolution in recent years has become a global concern. Humanities scholars have experienced the crisis of humanities due to the new wave of this revolution based on science and technology and expressed much concern. The problem is that humanities scholars themselves think ‘there is no hope for the future of the humanities.’ In any age or environment, humanities can always exert their worth when they are faithful to the human spirit that comes within our spiritual human nature. Humanities have a mission to elevate the spirit of man spiritually, making life vital. In this way, humanities heal and make people healthy; thus indeed constituting the hope of human life. What we need in the face of the uncertainty of life brought about by the Fourth Industrial Revolution is a ‘Humanities of Hope’ which expresses and becomes hope for the future. The humanities of hope, moreover, must above all become the ‘humanities of healing’ which heals the souls of human beings abused by science and technology. This will strengthen existence through a positive affirmation of existence and overcome all irregularities and impurities through the search and discovery of meaning.
