In this paper, we design a system that can control unmanned mobile objects through communication between unmanned mobile object and control server system using LoRa network which is a dedicated IoT network. It is more efficient when the unmanned mobile object performs the special work by installing the LoRa network applied to the unmanned mobile object control system from the small space house or office hospital to the factory. In this paper, we will discuss the design of a system that can improve the social utilization of unmanned mobile objects by making it possible to communicate the events that occur around other mobile objects from the simplification of the navigation path.

Gartner에 따르면 현재 IT산업에서 배출하는 Co2의양은 전 세계 배출량의 2%에 해당하고, 국내 IT기기의 탄소 배출량은 1,750만톤, 2012년에는 2,110만 톤으로 증가할 것으로 예상하고 있다. 이 중 전 세계 기업의 전산설지 전력 소비량은 1척억kWh가 소모되고 있으며, 서버의 전력소모량은 매년 20%씩 증가할 것으로 보고 있다. 또한 IT 시설물은 이산화탄소가 배출되는 7%의 가장 높은 비율을 차지하고 있다. 이에 따라 에너지 경비 절감 및 효율성을 높이고 탄소 배출량 감소를 위한 기술 및 솔루션 개발을 위한 그린 IT기술의 필요성이 높아지고 있다. 이러한 IT 시설물의 에너지 사용량을 실시간으로 확인, 온 습도 센서를 통한 자료 분석을 통하여 대상시설에 맞는 탄소배출량을 환산하여, 이를 활용한 에너지 시설의 제어를 통해 탄소배출과 경비를 절감시키는 시스템이 스마트탄소 통합관제시스템이다. 그리하여 본 논문에서는 통신 프로토콜 단에서부터 '관제'시스템의 성격에 맞고, 저장소의 공간을 효율적이고, 탄소 배출량을 감축시키는데 일조하는 스마트탄소 통합관제시스템의 프로토콜을 설계하고, 이를 테스트 하였다.

The tasks of Vessel Traffic Services are classified according to the content of the information provided. Since the establishment of the first Vessel Traffic Service center in 1993 at Phohang harbour, it has been steadily developed and its work domain and scope have been expanded. In this paper, the importance and workload of Vessel Traffic Service operators were analyzed according to classification of the tasks. In order to measure the importance and workload, questionnaires were conducted for the operators nationwide, and conclusions were drawn using the multi-criteria decision making process. The relationship between the importance of tasks and the workload might be used as the weights for setting the service areas in the future. Furthermore, it is expected to be used as the data of changable sector operation based on the relationship between importance and workload.

코로나19 팬데믹은 현실뿐만 아니라 사이버 공간에도 지대한 영향을 미쳤다. 재택근무와 비대면(온라인) 회의 뿐만 아니라 온라인 게임/쇼핑과 스트리밍 서비스 등과 같이 네트워크를 활용한 서비스의 이용자가 급증하였으며, 이로 인해 사이버 공간은 더욱 활성화되고 확장되었다. 그러나 사이버 공간의 확장은 이를 대상으로 하는 사이버 공격들도 함께 증가시켰으며, 그 피해규모 또한 증가하고 있어 대응방안 마련이 매우 시급한 상황이다. 본 논문에서는 코로나19 팬데믹 영향에 따른 사이버공격 동향을 살펴보고, 실제 사이버위협을 탐지·대응하는 보안관제, 침해대응 실무현장에서 발생하는 사이버위협을 분석해 사이버위협 동향 변화를 확인해 본다. 또한, 대응기술로서 인공지능과 설명가능 인공지능 기반 정보보호 연구·개발에 대해 소개한다.

This paper proposes the application of LoRa network, which has been under various research recently, to use control system for the transfer of Unmanned Vehicle. LoRa( Long Range) has a wide coverage of up to30 km, and is characterized by large-scale low-power long-distance radio communication. LoRa has already been studied in various industries. It is also proposed to study various functions by utilizing LoRa network and applying it to the control system of the uninhabited entity.

We already have seen many studies and articles about the methodology responding the security risks and threats. But we still have some controversial subjects to be settled. Now, we are living in the era that we should focus on how to use the security systems instead of how to make it. In this point of view, a company need to find out the answer for these questions, which security risks have to be handled in a corporate, which system is better for responding the security threats, and how we can build necessary security architecture in case of developing systems. In this article, we'd like to study on-site scenarios threatening the corporate assets, the limit on dealing with these threats, and how to consolidate the security events and information from enormous assets. Also, we'd like to search for the direction form the actual cases which have shown the desired effect from converging the assets and network informations.

IT 산업의 발전과 함께 Big-Data 와 보안은 빠른 속도로 발전하고 정보보호를 위해 다양한 시스템을 구축하는 것보다는 이를 연계하고 활용하는 것이 중요한 시대가 도래하였다. 한 기업이 가지고 있는 기업정보유출사고 등 다양한 해킹공격 또한 꾸준하게 증가되고 있다. 더불어 경제적 사회적인 손실이 증가되면서 국가 및 기업 상위 감사 기관은 정보보호 관련 법 제도를 제정하고 이를 강화하여 개정 하고 있다. 하지만, 물리적, 관리적, 기술적으로 연계된 통합 보안 관리 체계가 제대로 구현되지 않는다면 다양한 취약점을 통하여 기업 정보는 언제든 유출 될 수 있다. 본 논문에서는 기업에서 기 운영중인 정보보안 솔루션과 물리보안 솔루션이 효과적으로 통합 보안 관제가 가능한 IMP 플랫폼 구성설계 방안과 불법 침입 및 보안 사고 탐지를 위한 복합시나리오 설계 방안을 제시하여 실 적용 효과를 알아보고 향후 연구 방향을 제시하고자 한다.

An offshore plant needs costly maintenance and has difficulty coping with various accidents coming from the exposure to the environmental threats such as typhoons, tidal waves and etc., in addition to the artificial ones such as fire, collision of ships and etc. In this paper, we develop the video-complex remote monitoring system for an offshore plant, using AtoN AIS and multi-stage database to monitor an offshore plant and solve those problems. The system handles real time video cameras to collect and monitor images on an offshore plant. So, users can be exactly and quickly aware of the information on various situations with the monitoring application based on ENC.

When an applicant requests the emergency situation call or safe return service using a smart device, the smart surveillance service can select the CCTV(closed circuit television) cameras around the applicant using applicant's location information, then automatically takes a photograph to track the applicant. Since the surrounding CCTV camera shoots the applicant continuously using location information and the applicant can be observed by the monitor agent in real time, this service can be very helpful in an applicant's emergency situation or safe return. The existing smart surveillance service does not consider the priority of the emergency situation call and safe return service. Therefore, there is the disadvantage that the applicant who requests an emergency situation call service can not be photographed when safe return service has already preoccupied CCTV cameras which are capable of taking a picture of the applicant. The proposed smart surveillance service improves this disadvantage by using service priority.

This study intended to exploratively testify human error causing factors for railway traffic controller, using AMOS structural equation model. Through literature survey, fatigue and stress as exogenous variable, errors in information process such as cognitive, memory, storage, and execution error as endogenous variable, and accident and incident(near-miss) as dependent variable were set up. Results based on AMOS using 201 railway traffic controllers' questionnaire showed that a clear causality loop like as 'stress ${\rightarrow}$ memory error ${\rightarrow}$ storage error ${\rightarrow}$ incident(near-miss) ${\rightarrow}$ accident' is formed. This result suggests that for the purpose of mitigation of traffic controller's accident, it is so necessary to reduce memory and execution error in the information processing process based on the effective management of stress, as the precedent of them.
