해저공간을 인류의 삶의 터전으로 바꾸기 위해서는 거주자의 안전이 반드시 확보되어야 한다. 하지만 해저거주공간에서 발생할 수 있는 재난과 재난 발생 시 이루어지는 피난의 특성에 대해서는 연구가 적다. 그러므로 본 연구에서는 해저거주공간의 재난 및 피난 특성에 관해 연구를 진행한다. 현재 운용 중인 해저거주공간의 사례가 드물어 우선 수중공간에서 장기간 임무를 수행하는 잠수함의 사고 사례와 수중연구실로 운영되고 있는 수중해비타트의 사고 사례를 분석하여 해저거주공간의 재난 및 피난 특성을 도출한다.

The sinking of the M/V SEWOL in April 2014 was not a mere marine accident, but a marine catastrophe. This grim case developed into a social tragedy that impinged the national sentiment and communal integrity. It is imperative that thorough provisions and measures be outlined at the national level with regard to massive marine accidents, oil pollution, and natural disasters that might critically affect government affairs. Pivoting on "The Black Swan Theory," a concept of improperly rationalizing a national crisis based on uncertainties, this research assesses a variety of response strategies that minimize the national economic and social damage caused by a large-scale marine disaster. Along with the effort of minimizing any potential defects in each protective barrier, the "Black Swan Detection System of the Marine Disaster" needs to be incorporated to prevent cases wherein such defects lead to an actual crisis. Maritime safety must be systematically unified under a supervisory organization, and a structure for maritime crisis on-scene command and cooperation must likewise be established in order that every force on the scene of a marine disaster may act effectively and consistently under the direction of an on-scene commander.

Quality control (QC) to process observed time series has become more critical as the types and amount of observed data have increased along with the development of ocean observing sensors and communication technology. International ocean observing institutions have developed and operated automatic QC procedures for these observed time series. In this study, the performance of automated QC procedures proposed by U.S. IOOS (Integrated Ocean Observing System), NDBC (National Data Buy Center), and OOI (Ocean Observatory Initiative) were evaluated for observed time-series particularly from the Yellow and East China Seas by taking advantage of a confusion matrix. We focused on detecting additive outliers (AO) and temporary change outliers (TCO) based on ocean temperature observation from the Ieodo Ocean Research Station (I-ORS) in 2013. Our results present that the IOOS variability check procedure tends to classify normal data as AO or TCO. The NDBC variability check tracks outliers well but also tends to classify a lot of normal data as abnormal, particularly in the case of rapidly fluctuating time-series. The OOI procedure seems to detect the AO and TCO most effectively and the rate of classifying normal data as abnormal is also the lowest among the international checks. However, all three checks need additional scrutiny because they often fail to classify outliers when intermittent observations are performed or as a result of systematic errors, as well as tending to classify normal data as outliers in the case where there is abrupt change in the observed data due to a sensor being located within a sharp boundary between two water masses, which is a common feature in shallow water observations. Therefore, this study underlines the necessity of developing a new QC algorithm for time-series occurring in a shallow sea.

해양 디지털 트윈 구축을 위해서는 바다와 인접한 육상공간, 해상 및 해저 공간 등의 공간 정보와 시시각각 변하는 해양 환경 데이터, 그리고 해양 생태계 및 해양 자원 등 관련된 해양 데이터를 수집하고 이를 트윈에 적용하는 것이 필수적이다. 본 논문에서는 해양 디지털트윈 구축을 위해 필요한 해양 데이터의 국내 제공 현황을 정리하였다.

The Enforcement Decree of the Framework Act on the Management of Disasters and Safety Article 3-2 specifies two 'disaster management supervision agencies' for responding to shipping disasters. These are the Korea Coast Guard, which is an on-scene disaster-responding and coordinating agency, and the Ministry of Ocean and Fisheries, which is a government department, thereby leading to possibilities for confusion. In the case of shipping disasters, where a personnel entitled full power to deal with shipping disasters is designated and his/her powers and duties are clearly made, relationship of leading and supporting agencies is made clear, and command system is simplified, an efficient response to shipping disasters is made possible. In the management of shipping disasters, all the disaster management processes, that is, prevention-preparedness-response-recovery, should be dealt with systematically and consistently. Notably, to swiftly and efficiently cope with a disastrous situation, the decision-making and command system must be simplified. The establishment of a command system and decision-making must be made independently, based on expertise. In the US, irrespective of the type of disasters, the FEMA plays a leading role and the USCG responds a response to maritime disasters by establishing the Incident Command System or Unified Command System that is an incident management system. In the UK, the MCA supervises an event and responds to it, and the SOSREP has full power to work with command and coordination independently. SOSREP, among others, is necessary to prevent an inefficient dealing of a shipping disaster owing to confrontation between participants. With reference to such leading States' practice, the Korean government should make a standardized and simplified response to maritime disasters. This study deals with a new maritime disaster responding system and provides an idea of the revision of the existing legal regime.

세월호 이후 안전교육의 중요성이 강조되고 있어 해양안전 기초교육 표준 모델을 정립 할 필요성이 제기되고 있다. 해양산업계에서는 선원법에 의해 기초안전교육, 상급안전교육으로 법정 교육으로 강제하고 있으며, 해기사에 대해서는 BRM 교육이 실시되고 있다. 이를 일반 국민에게 적용하기 위한 바다 물놀이 안전수칙, 선박 안전수칙, 재난선박 안전수칙에 대한 표준 교육 모델을 제시하여 교육 현장에 적용하고 해양안전 문화확산의 기초 자료로 사용하고자 한다.
