The fire incident of KT's Ahyun branch occurred last year indicates that hyper-connected society led by 5G technology would be a dystopia instead of a utopia unless seamless connection of 5G service is well secured. Looking backward on 1999, we could peacefully and happily greet the new millennium by making a great effort to prevent the millennium bugs(Y2K) from causing the catastrophe such as a shut-down of banking system. Likewise, we should make a great effort to keep 5G networks and 5G service continuously working without the disruption of even just a second, which would enable us to avoid facing any catastrophes caused by the disruption of 5G service. As a way to do so, it can be considered that 5G service is designated as universal service because it has the key features of public goods like telephone and high-speed internet services.

Passenger casualties in the case of ship accidents have increased because of the increase in size and complexity of current ships (such as cruise ships). Therefore, in recent years, emergency evacuation systems are receiving increased interest so as to ensure the safety of passengers. Currently, there are only basic instructions provided, such as announcements regarding the situation, alarms, and exit signs; however, no guidance toward a proper escape route has yet been provided. To solve this problem, several emergency guiding schemes have been proposed. However, these systems ignore some of the realities of ship accidents and are impractical because various risk factors are not considered. Therefore, this paper proposes an optimal route guiding system based on an $A^*$ algorithm for emergency escape during disaster situations. This system takes into account various possible risk factors. Performance evaluation using computer simulations showed that the proposed scheme is effective and leads to safe escape routes.

The current state monitoring system at a semiconductor manufacturing process is based on the manually collected sensor data, which involves limitations when it comes to complex malfunction detection and real time monitoring. This study aims to design a situation recognition algorithm to form a network over time by creating a domain ontology and to suggest a system to provide users with services by generating events upon finding risk factors in the semiconductor process. To this end, a multiple sensor node for situational inference was designed and tested. As a result of the experiment, events to which the rule of time inference was applied occurred for the contents formed over time with regard to a quantity of collected data while the events that occurred with regard to malfunction and external time factors provided log data only.

Unexceedingly rapid industrialization in Korea produced not only the improvement of living standards but many side effects including safety problems. This study, utilizing the survey data on 800 respondents on the quality of life and psycho-physical safety, reveals several findings as follows: 1) safety is one of the key dimensions of quality of life, 2) people usually take an equilibrium between risk and safety, although the equilibrium point differs by culture, social system, and other demographic traits, 3) accidents can be classified into three different types, demanding a different approach on the cause process, and solution in safety-related accidents. Major findings of this study implies that for the improvement of the quality of life, we should prescribe different policy measures according to the three different types of accidents.

U. S. and NATO allies have recently increased their emphasis on reducing the hazards of tactical munitions that contain energetic materials and actively started many investigations on Insensitive munitions(IM) of missile propulsion. All subcomponents of rocket motor should be properly designed and understood to increase IM properties. Insensitive propellant, motor case, ignitor and mitigation devices are important components of IM technologies of rocket motors.

We have noted a possibility of big data as a solution of social problem and pending issue. At the same time big data has a problem of privacy. Big data and privacy were in conflict. In this paper we pointed out that issue and propose a planning of big data based on privacy using case study of advanced country.

금융과 IT의 융합을 의미하는 핀테크(Fintech) 열풍이 전세계적으로 뜨겁게 불고 있다. 핀테크를 통해 신기술들이 금융 산업 전반에 융합되면서 새로운 형태의 금융서비스가 등장하고 기존의 금융 시스템들이 가져왔던 문제점들을 개선하는데 기여할 것으로 보인다. 하지만 핀테크 산업 활성화를 위한 지속적 규제 완화와 이용자 편의성을 위한 각종 절차의 간소화 그리고 채널 서비스 기술간의 융복합이 일어나는 환경에서 제공되는 핀테크 서비스의 안전성에 대해 우려가 있다. 핀테크 시대에 정보보안은 성장의 인프라이며 금융상품을 선택하는 중요한 기준이 될 것이므로 보안리스크의 정량화와 단계별 통제 방안을 수립하고 사용자 인증, 결제정보 보안, API(Application Programming Interface) 보안 등 필요한 보안요소를 사업모델에 맞게 적용함으로써 편리성과 보안성을 함께 확보할 수 있어야 한다. 본 연구에서는 정보보안 관점에서 핀테크의 서비스의 특징과 보안 취약점을 분석하고 관련 위험을 줄이기 위한 대응방안을 모색해 보았다.

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.

기후변화의 영향으로 발생 가능한 자연재난들에 대응하기 위해 많은 연구들이 활발히 수행중이다. 하지만, 대부분의 기후변화 연구들은 강수량의 증가와 해수면의 상승을 구분하여 재난의 영향을 평가하는데 그쳤고 기후변화로 인해 발생한 요소들의 복합적인 고려와 이로 인한 홍수 피해액 산정 연구는 미비한 실정이다. 이에 본 연구에서는 서쪽 산지에서 발원하여 울산 시가지를 관통하고 동해로 유입되는 태화강을 대상유역으로 선정하였고 기후변화로 인한 해수면 상승이 연안 지역과 인접하천에 미치는 영향을 평가하였다. 기후변화 따른 미래 강수량과 함께 해수면 상승의 복합적인 고려를 통해 기후변화의 영향이 연안지역의 수문량 변화에 미치는 영향을 분석하였다. 기후변화에 따른 해수면 상승이 연안지역에 얼마나 영향을 미치는지 확인하기 위해 강수의 증가량과 해수면의 상승량에 따른 홍수범람도를 작성 비교하였고 이를 정량적으로 비교하기 위해 홍수 피해액을 산정하였다. 해수면 상승으로 인한 하천의 기점수위가 높아짐에 따라, 전체적인 홍수위가 상승하는 것으로 나타났으며, 홍수위 상승은 하구에 가까울수록 상승폭이 큰 것으로 나타났다. 해수면 상승에 따른 침수심 및 피해지역의 변화는 홍수 피해액에도 영향을 미치는 것으로 확인할 수 있었다. 연안지역에 위치한 하천에서는 기후변화에 따른 강수량의 증가뿐만 아니라 해수면 상승량의 변화도 계획홍수위, 홍수범람 및 홍수 피해액에 분석에 있어 중요한 요소이며, 본 연구의 결과는 향후 연안 지역의 취약성 평가 기술과 풍수해 자연재난 위험의 대응방안 마련 기초 자료로 활용할 수 있을 것으로 판단된다.
