최근 건설되어지는 도시들은 정부의 신도시 정책의 일환인 첨단 도시 건설을 목적으로 하는 Ubiquitous City를 계획하고 있다. Ubiquitous City는 언제 어디서나 유비쿼터스 서비스와 인프라가 제공되는 환경을 가지고 있으므로 노출 위험이 높다. 보안을 고려한 개별 시스템들의 설계는 정부 정책과 함께 활발히 진행되지만 통합 시스템을 관리하는 면에서의 방안은 제시되지 못하고 있다. 보안관리방안이 성립되지 못한다면 침해 유형이 고도화되면서 항상 변화하는 유비쿼터스 시대에 보안은 취약해질 수밖에 없다. 시스템을 총괄 관리 및 관제하는 통합네트워크전산센터인 U-City전산센터의 보안 관리망을 구성하고 취약한 시스템들의 보안을 관리하는 대책이 필요하다. 본 논문에서는 유비쿼터스 보안망의 체계적인 관리 방안을 통합보안관리(ESM)를 중심으로 기술적인 보안관리대책을 제안한다. 제안된 보안관리대책이 Ubiquitous City를 계획하는 모든 신도시들의 플랫폼이 되도록 한다.

최근 공간정보를 다루는 GIS, SIIS, GNSS, ITS 네 개의 시스템에 대한 통합연계 기술인 4S 기술이 각광받고 있다. 본 논문에서는 컴포넌트 기반의 4S 시스템을 소개하고 4S 기술을 화재, 홍수, 태풍 등의 재난재해 분야에 적용한 시스템을 4S 핵심 컴포넌트를 중심으로 설계하였다. 4S 기술을 이동 환경에서 적용하는 예는 매우 많으나 재난재해 업무에 적용될 경우 매우 큰 효과를 가져올 것이다. 공간데이터를 처리하는 핵심 기술과 재난재해 업무간 공통된 기능은 4S 핵심 컴포넌트로 구현되며, 업무별로 다른 기능은 별도의 업무 컴포넌트로 분리하여 분야별 응용시스템에 따라 사용하게 하였다. 특히 4S-Van 이라는 차량 및 이동단말기 등 현장과 중앙관제센터간에 실시간으로 위치정보와 영상정보 등을 전송하는 방법 및 전송된 정보를 중앙관제센터에서 공간 데이타와 연동.분석하는 방안을 제시하여 신속하고 정확한 상황파악, 의사결정, 지령관제 등을 가능하게 하고 재난재해 분야에 획기적인 업무효율 향상을 가져올 것으로 기대된다.

Recently increase in the number of aircraft caused the air traffic congestion and flight delays. If timely action to reform the air traffic system is not taken, these may result in added economic impact. As a result, the air traffic management should be changed in an innovative manner to modernize the existing air traffic control environment. This paper reviews the trends of airspace reforms such as integration of terminal control areas and flexible use of airspace introduced by foreign countries and compares their merits and demerits in order to provide a judgement to adopt the concept in domestic airspace in the future.

Recently, the maritime environment contaminated by the abandoned fishing gears. To solve this problem, there requires systematic management techniques for the fishing gears based on ICT technologies. The existed systems are optionally used by owners, but the systems need to adopt the monitoring and control architecture for integrated national surveillance. To do this, we designed an architecture for effective monitoring and management which collects position and state information using automatic identification buoy (AIB) device, to send the fishing ship, administrator ship, and shore side control center based on the IoT networks. Especially, in this paper, we developed the ENC-based integrated control system for efficient management which provides functions for position indication, state information display and loss alarm of fishing gears. Also, we conduct performance tests for data processing and visualization functions of the system to use a virtual buoy generation module.

Dengue virus transmission is a viral infection disease between humans and Aedes mosquitoes. Dengue is ubiquitous throughout the tropics and subtropical zones, where 1/3 of the global population live. The weather in Korea is also changing to subtropical weather, resulting in increased vulnerable Korean population to dengue virus transmission. It is important to control and prevent the dengue risk with track-recording & monitoring system. It is also required to have the control system to treat and monitor dengue patients with various cases such as regions, ages, genders according to the track-record of the disease. In this paper, we developed a Dengue Control & Prevention System, which can monitor and control dengue outbreaks in real-time with in-vitro diagnostic devices. Dengue Control & Prevention System is composed of in-vitro diagnostic device, which is a fluorescent immunoassay, and real-time monitoring system. In the future, we expect that our Dengue Control & Prevention System can be upgraded to have various disease information from Korea Disease Control and Prevention Agency for government policies and diseases control in Korea.

Cloud computing-related security incidents have occurred recently are beyond the scope of a enterprise's security incident is expanded to the entire range of customers who use the cloud computing environment. The control technology for the overall integrated security of the cloud data center is required for this purpose. This study research integrated and additional security elements for the cloud data center control to understand the existing control technology. It is a better understanding of the IaaS cloud environment to build the IaaS cloud environment by CloudStack. SW-IaaS cloud structure by combining CloudStack and IaaS cloud model presented by NIST is proposed in this study. This paper derive a security framework to consider in each layer of The SW-IaaS cloud components, which are composed of the Cloud Manager, Cluster Manager, and Computer Manager.

In South Korea, a cloud-based vessel traffic service (Cloud VTS) system integrating the fourth industrial revolution technologies such as cloud and AI is currently under development in contrast to the existing VTS systems. A pilot center for at Busan VTS is being established based on differentiated technology and operational programs. The roles of operators and maintenance personnel who operate the innovative Cloud VTS system must be redefined. Additionally, a demand exists for the development of new educational programs to ensure the smooth operation of the Cloud VTS. Therefore, this study introduces the development details of a Cloud VTS system and explores educational strategies aimed at operators and maintenance personnel to ensure its safe operation.

In Seoul, about 75,000 CCTVs are installed in 25 district offices. Each ward office has built a control center for CCTV control and is performing 24-hour CCTV video control for the safety of citizens. Seoul Metropolitan Government is building a smart city integrated platform that is safe for citizens by providing CCTV images of the ward office to enable rapid response to emergency/emergency situations by signing an MOU with related organizations. In this paper, when an incident occurs at the Seoul Metropolitan Government Office, the escape route is predicted by discriminating people and vehicles using the AI DNN-based Template Matching technology, MLP algorithm and CNN-based YOLO SPP DNN model for CCTV images. In addition, it is designed to automatically disseminate image information and situation information to adjacent ward offices when vehicles and people escape from the competent ward office. The escape route prediction and tracking system using artificial intelligence can expand the smart city integrated platform nationwide.

선박자동식별장치(AIS)는 선박의 선명, 제원 등 선박 정보, 운항정보 등을 선박과 선박 간, 선박과 관제센터 간 자동 송수신하는 장치다. 현재 국내에서는 전국 통합망 구축 사업 완료를 통해 AIS와 시스템이 본격적으로 운용되고 있다. 이러한 AIS 정보는 선박 대 선박 간의 충돌회피, 연안국이 불분명한 선박 및 그 화물에 대한 정보 획득, 선박 대 육상간의 통항관제를 위하여 사용된다. 하지만, 어선들은 생계와 관련된 어망의 위치가 노출되기 때문에, AIS 사용을 꺼려한다. 본 논문에서는 어선들의 위치가 노출되지 않도록 위치 정보를 암호화하고 인증하는 신뢰성 있는 AIS 통신 프로토콜을 제안한다.
