연안선은 국제항해 선박에 비해 상대적으로 사고의 위험성은 높으나 이에 대응할 훈련기반이 취약하다. 본 연구에서는 연안선의 화재 및 퇴선상황에서의 승무원의 행동특성을 모델링하고 연안선 환경과 특성에 맞는 CBT용 훈련 프로그램을 개발함으로써 비상시 연안선 승무원의 사고대응 능력을 제고하고자 한다. 특히 이를 위해 연안 여객선에서 여객 대피를 위해 필요한 요소를 검토하여 개선점을 파악하여 프로그램 개발에 반영하고자 한다.

지난 11월 10일 한국전력공사 영광원자력본부에서는 원전에서의 방사능누출사고 발생시 사고복구 및 주민보호를 위해, 과학기술처$\cdot$내무부$\cdot$전라남도$\cdot$전라북도$\cdot$영광군$\cdot$고창군$\cdot$한국원자력안전기술원$\cdot$한국전력공사 본사$\cdot$영광원자력본부 관계자 및 지역주민 등 약 400여명이 참여한 대규모 방사능방재훈련이 있었다. 훈련은 일부 주민에 대한 실질적인 대피, 헬기 및 해상함정을 동원한 공중 및 해상의 환경방사능 측정, 화재진압, 부상자 구호, 발전소 사고복구, 관련기관간 유기적인 정보교환 등 실제 및 도상으로 처리하는 훈련을 통해 만약의 비상사고시 효율적으로 대처할 수 있는 능력을 배양하는 데 주안점을 두었다. 금번 훈련의 가장 중요한 의의는 우리나라에서 지역주민이 처음으로 대피훈련에 참여함으로써 실질적인 비상대응능력 확보에 기여하였다는 점이다.

Cloase-range image information from drones and ground-based camera has been frequently used in the field of disaster mitigation with 3D modeling and mapping. In addition, the utilization of virtual reality(VR) is being increased by implementing realistic 3D models with the VR technology simulating disaster circumstances in large scale. In this paper, we created a VR training program by extracting realistic 3D models from close-range images from unmanned aircraft and digital camera on hand and observed several issues occurring during the implementation and the effectiveness in the case of a VR application in training for disaster mitigation. First of all, we built up a scenario of disaster and created 3D models after image processing with the close-range imagery. The 3D models were imported into Unity, a software for creation of augmented/virtual reality, as a background for android-based mobile phones and VR environment was created with C#-based script language. The generated virtual reality includes a scenario in which the trainer moves to a safe place along the evacuation route in the event of a disaster, and it was considered that the successful training can be obtained with virtual reality. In addition, the training through the virtual reality has advantages relative to actual evacuation training in terms of cost, space and time efficiencies.

승객대피분석은 승객이 안전한 최종 탈출지점까지 대피하는데 걸리는 시간을 산출 하는 것과 다수의 승객이 하나의 대피경로로 몰리면서 정체현상이 일어나는지를 판단하는 것이 중요하다. 본 논문에서는 무선측위 정보를 활용하여 데크별 선내인원정보를 확인하고 이를 바탕으로 안전한 탈출지점까지 모든 승객이 대피하는데 걸리는 시간이 실시간으로 산출 가능한 기술을 승객안전 대피지원 시스템에 적용하였고 선박의 운용중 발생 가능한 사고 대응시 초기대응에 도움을 주고 위기사항이나 승무원의 훈련에도 활용 가능하도록 제시하고자 한다.

본 연구분석결과 훈련 이벤트가 다수 적용될 때 훈련 참여자의 참여율, 관심도 및 화재대응자세가 많이 향상되고 훈련계획시 훈련 참여자들의 초기대응능력(화재통보 및 화재신고, 초기소화, 화재대피) 향상과 유지에 훈련목표를 두고 각 대응단계별 목표시간을 설정한 후 이를 기반으로 정량적인 훈련평가를 하여야만 화재대응능력 향상과 향후 화재모의훈련의 개선 및 피드백에 유용한 지표로 활용될 수 있다는 결과를 도출하였다.

The development of North Korea's nuclear weapons has worsened to the sixth nuclear test in 2017, and despite the sanctions of the international community including our government, we have not been able to offer clear solutions and alternatives, and the current measures are not enough in case of North Korea is using nuclear weapons. This study suggests how we should be prepared against the use of nuclear weapons under the premise that North Korea will never give up development of nuclear weapons under any circumstances. The first chapter outlines the current status of our preparedness if North Korea makes a nuclear attack. The second chapter analyzes and evaluates the power of nuclear weapons and North Korea's nuclear weapons threat. In the third chapter, we analyze North Korea nuclear attack and analyze the wartime emergency situation and civil defense posture. Finally, in order to implement the solutions presented in the text, we will identify priorities and summarize further developments.

다중 이용시설, 학교, 주택 등 사람이 많이 이용하는 곳은 화재 발생 빈도가 높을 뿐만 아니라 대피하기가 어렵고, 기존의 비상등 표시 방법, 일회성 대피 안내 등으로 인해 화재 상황의 다양한 변수에 효과적으로 대처하기 어렵다. 본 논문에서는 디지털 트윈(Digital Twin) 기술을 기반으로 다양한 센서를 통해 인식된 화재 요소를 반영한 화재 대응 및 피난 시뮬레이션(Fire Dynamic Simulator & Pathfinder)을 통해 안전한 대피 경로를 도출하여 안내하는 시스템을 설계한다. 제시하는 방법은 화재 상황에 능동적으로 대처하기 위해 실시간 인원변동 및 변화하는 화재변수에 대비 할 수 있으며, 상황에 따른 적극적인 대피 훈련과 실제 상황에서의 긴급한 상황에서의 대피경로 도출과 안내에 활용할 수 있다.

Virtual reality, one of the core technologies of the 4th industrial revolution, is entering a new phase with the spread of low-cost wearable devices represented by Oculus. In the case of disaster evacuation drills, where practical training is almost impossible due to the risk of accidents, virtual reality is becoming a new alternative that enables effective training. In this paper, we propose a smoke modeling method that can be applied to fire evacuation drills implemented with virtual reality technology. In the event of a fire, smoke spreads along the aisle, and the density of the smoke changes over time. The proposed method models the smoke by applying a procedural function that can reflect the density of smoke calculated through simulation to the model in real-time. Implementation results in the background of the factory show that the proposed method produces models that can express the smoke according to the user's movement.

The most effective and economic way for the mitigation planing against tsunami disasters is to develop an emergency action plan along the coastline vulnerable to unexpected tsunami attacks. The plan should be developed based on the historical tsunami events and the projected scenarios. In this study, an evacuation simulation is made based on the projected scenarios at Imwon Port as a part of the emergency action plan. The produced simulation could be used by the authorized organizations in a disaster training against tsunami attacks.

It is critical that passengers should be given timely and correct escape or evacuation guidance from captain and crews when there are hazardous situations in a ship. Otherwise the consequences could be disastrous as "SEWOL Ferry" the South Korean passenger ship which sank in southern coastal area on 16th April 2014. Due to the captain's delayed evacuation decision and lack of sufficient number of crews to guide passengers' evacuation, the accident recorded many casualties, most of whom were high school students (302 passengers sank down with the ship while 172 rescued). Building a passenger ship with well-designed physical escape routes is one thing and guiding passengers to those escape routes in real disaster situation is another. Passengers get panic and move to a wrong direction, bottleneck makes situation worse, and even crews get panic also - passive static escape route signage and small number of trained crews might not be enough to take care of them. SESS (Smart Escape Support System) is being developed sponsored by South Korea Ministry of Ocean and Fisheries starting from 2016 with 4 years of roadmap. SESS comprises multiple active dynamic signage devices which communicate with real-time escape routing server software via LoRa (Long Range) proprietary wireless network.
