In recent years, many people are living in a space limited by rapid global industrial development and economic growth, and rapid urbanization is underway, with the global urban population estimated to be more than 70 percent in 2050. Due to rapid urbanization, government-led smart city models are being developed and introduced to solve various urban problems such as disaster safety, air pollution, water pollution, energy shortage, disease, crime and transportation. However, since ICT technology of public housing is being developed as a type of social overhead capital project, it is necessary to develop micro-smart city projects that residents can feel by developing services such as public safety, living environment, living welfare, and energy management for public housing residents. Therefore, in this paper, the smart platform model of public housing for smart city in the era of the Fourth Industrial Revolution is planned and presented.

The government is pursuing plans to create new e-government services. In terms of improving business procedures, dBrain (finance), e-people (personnel), and Onnara (electronic payment and business management) have achieved considerable results, and are currently making efforts to improve existing administrative services using newly emerged ICT. Among them, this paper attempted to study whether self-learning-based intelligent administrative services are efficient in the work process of public officials promoting actual work and affect their continued use. Based on individual perceptions and attitudes toward advanced ICTs such as AI, big data, and blockchain, public officials' influences on administrative services were identified and verified using UTAUT variables. They believe that the establishment and introduction of innovative administrative services can be used more efficiently, and they have high expectations for the use and provision of services as ICT develops. In the future, a model will be also applied to citizens

The development and distribution approach of applications is transitioning from a monolithic architecture to microservices and containerization, a lightweight virtualization technology, is becoming a core IT technology. However, unlike traditional virtual machines based on hypervisors, container technology does not provide concrete security boundaries as it shares the same kernel. According to various preceding studies, there are many security vulnerabilities in most container images that are currently shared. Accordingly, attackers may attempt exploitation by using security vulnerabilities, which may seriously affect the system environment. Therefore, in this study, we propose an efficient automated deployment pipeline design to prevent the distribution of container images with security vulnerabilities, aiming to provide a secure container environment. Through this approach, we can ensure a safe container environment.

Smart Farm means creating new value in various fields related to agriculture, including not only agricultural production but also distribution and consumption through the convergence of agriculture and ICT. In Korea, a rental smart farm is created to spread smart agriculture, and a smart farm big data platform is established to promote data collection and utilization. It is pushing for digital transformation of agricultural products distribution from production areas to consumption areas, such as expanding smart APCs, operating online exchanges, and digitizing wholesale market transaction information. As such, although agricultural data is generated according to characteristics from various sources, it is only used as a service using statistics and standardized data. This is because there are limitations due to distributed data collection from agriculture to production, distribution, and consumption, and it is difficult to collect and process various types of data from various sources. Therefore, in this paper, we analyze the current state of domestic agricultural data collection and sharing for digital agriculture and propose a data collection and linkage method for artificial intelligence services. And, using the proposed data, we propose a deep learning-based environmental factor recommendation method.

IoT, Big-data, AI, and Cloud technologies, which are core technologies of the 4th Industrial Revolution, have recently been applied to various fields and are being used as core technologies for new growth engines. Accordingly, these core technologies are applied to the agricultural field without exception, contributing to solving the problem of labor shortage, reducing production costs, and reducing environmental burden through remote and automated production without time and space constraints. However, as these core technologies are utilized, security incidents are occurring in the agricultural field as well. Accordingly, this study divides smart farms into three stages(Basic, Middle, and High) and presents the characteristics and security threats of each stage. In particular, as the number of container-based services and research increases under cloud platforms, we would like to suggest countermeasures focusing on security threats.

Alvin Toffler는 인류 발전 과정을 세 가지 변화의 물결, 즉 유목 채집 사회에서 농경 사회로의 변화, 산업혁명에 의한 농경 사회에서 산업 사회로의 변화, 그리고 1950년대부터의 후기 산업화 사회로의 변혁으로, 산업 사회에서 정보 사회로의 변혁이 일어나기 시작했으며 탈대량화, 다양화, 지식기반 생산과 변화의 가속이 시작된 시기였다. Herman Maynard와 Susan Mehrtens는 ICT (Information Communication Technology: 휴대폰 등), 인터넷의 발달로 제4의 물결이 시작되고 있다고 주장한다. 이전의 사회 변혁들은 물질 생산이 따르는 가시적인 변혁들이었으나, 디지털 혁명은 시민사회의 참여 확대를 통한 민주주의의 진화된 형태를 가능하게 하고 있다. 지금 우리가 경험하고 있는 제4의 물결의 시작은, 시민사회의 정책 참여와 견제가 효과적이고 효율적으로 이루어지기 시작하는 초고도 정보화 사회의 시작을 의미하며, 정책 결정 자들은 정책 결정 과정에서 그들이 보유하던 절대 영향력의 일부분을 시민사회에 이양됨을 막을 수 없을 것이다. 이러한 대변혁의 시대에 관료주의, Digital Divide, 그리고 시민 참여와의 상관관계를 이해하는 것은 매우 중요하다. 본 논문에서는 시민 참여에 대한 관료주의의 방침과 태도, 제4의 물결의 정책 민주화와 Digital Divide로의 영향 분석을 통하여 정책 결정 자들과 그들의 환경으로의 파급 효과를 논증한다. 본 연구는 이러한 분석과 논증을 통하여, 정책조직들과 시민사회와의 신세기의 바람직한 동반자적 입지 구축에 기여 할 것이다.
