Maritime Autonomous Surface ships(MASS) are gradually gaining importance. Until fully autonomous ships are developed, they will likely be controlled by remote operators who are based in a Remote Operations Center. However, there is currently no internationally or domestically established licensing for them. This issue can potentially pose a risk to navigation safety due to operations being handled by unqualified remote operators. We conducted a literature review and proposed criteria for the adoption of a licensing system for remote operators. We have futher offered alternatives to integrate this license into the existing officer licensing system, and analyzed them using Analytic Hierarchy Process(AHP). Subsequently,, theprimary need to enact legislation for remote operators is observed. The most preferred approach is to include the occupation of a remote operator in the Ship Officer Act, Article 4: Occupational Categories and Class of Licenses. Therefore, it would be logical for the organizational structure of the Remote Operation Center to mirror the traditional Bridge Resource Management. This study will contribute to the efficient training of remote operators and the safe navigation of autonomous ships with a focus on human resource management.

This paper's purpose is three-folded: modeling the self-regulating fire prevention system, developing a packet of practical fire prevention measures and regulations, and reviewing the applicability of fire insurance system in Korea as a main components of the self-regulating fore prevention system. The so called self-regulating fire prevention system is defined as a grand national fire prevention framework based on and promoted by the vitality and creativeness of the market (or private sector). This drastically contrasts with the existing government-led fire prevention system in Korea. The self-regulating fire prevention system has three grounds: the principle of self-responsibility, the redefinition of the fire service as a public goods, and the principle of self-selection. It seems natural that the self-regulating fire prevention system requires the function of fire insurance institution as a pivoting mechanism providing individual decision makers with a system of incentives, resulting in rational behaviors in the part of each individuals and in the well-balanced fire prevention network in the part of the overall public. In this regard, this pilfer examines the institutions and performance of the fire insurance industry in Korea and reviews the limitation of the industry as an instant replacement mechanism of the current government-led fire prevention system in Korea.

This study was undertaken to strategize the mixed traffic operation of autonomous vehicles in the pilot zone. This was achieved by analyzing the changes expected when autonomous vehicles are mixed in the autonomous vehicle pilot zone. Although finding a safe and efficient traffic operation strategy is required for the pilot zone to serve as a test bed for autonomous vehicles, there is no available operation strategy based on the mixture of autonomous vehicles. In order to presents a traffic operation strategies for each period of autonomous vehicle introduction, traffic efficiency and safety analysis was performed according to the autonomous vehicle market percentage rate. Based on the analysis results, the introduction stage was divided into introductory stage, transition period, and stable period based on the autonomous vehicle market share of 30% and 70%. This study presents the following traffic operation strategies. Considering the traffic flow operation strategy, we suggest the advancement of the existing road infrastructure at the introductory stage, and operating an autonomous driving lane and the mileage system during the transition period. We also propose expanding the operation of autonomous driving lanes and easing the speed limit during the stable period. In the traffic safety strategy, we present a manual and legal system for responding to autonomous vehicle accidents in the introductory stage, an analysis of the causes of autonomous vehicle accidents and the implementation of preventive policies in the transition period, and the advancement of the autonomous system and the reinforcement of the security system during the stable period. Through the traffic operation strategy presented in this study, we foresee the possibility of preemptively responding to the changes of traffic flow and traffic safety expected due to the mixture of autonomous vehicles in the autonomous vehicle pilot zone in the future.

자율운항선박은 센서, IoT, 빅데이터, AI, 플랫폼 등 고도의 ICT 요소 기술이 필요한 미래 유망 산업 분야이다. 특히 선박 내부장치로 부터 수집된 정보와 선박 주변의 해상 데이터가 증가될수록 선박 대 선박 및 선박 대 육상 간 정보 교환 체계인 해상통신망의 중요성은 커질수 밖에 없다. 해양수산부는 2020년 세계 최초로 대한민국 연안으로부터 최대 100km 까지 해역을 LTE(Long Term Evolution) 통신체계로 구축한 바 있다. 본 논문은 초고속 해상무선통신망(LTE-Maritime)이 자율운항선박의 주요 통신 기술로써 활용되기 위해 우선적으로 고려할 사항을 타 해상 무선통신 기술과의 연계, 업링크 및 항내 통신품질의 향상 관점으로 살펴보고자 한다. 이를 위해 LTE-M. 망의 무선설비 다각화 사업으로 추진중인 해양 드론용 송수신기의 실해역 성능 시험을 통해, 선박과 육상 간 정보 교환에 있어 상호운용성 시험의 중요성을 재고해 보고, 해상 무선통신 체계의 신뢰성 및 호환성을 확보하기 위한 무선품질지표, 상호운용성 시험 방법 등을 제시하고자 한다.

In order to trust and use autonomous vehicles, safe driving on the road must be guaranteed. For this, the first infrastructure to be equipped with autonomous driving is traffic safety facility. On the other hand, autonomous vehicles(Level 3) and general vehicles are driving on the road, it is necessary to additionally manage existing general traffic safety facilities. In this study, a field management system for traffic safety facilities based on autonomous driving infrastructure was studied, and a pilot field management system was implemented in the demonstration area(Pangyo). The pilot system consists of a GNSS(Global Navigation Satellite System) receiver, a field management equipment, and a field management app. As a result of field demonstration,, it was confirmed that traffic safety facility information was easily transmitted and received even in downtown areas and that could be efficiently operated and managed. It is expected that the results of this study will be used as reference materials for the spread of autonomous driving infrastructure to local governments and infrastructure construction in the future.

국토부가 2010년 1월부터 건설현장 자율점검제도 시행에 들어감에 따라 앞으로 현장책임자가 감리원 등을 활용하여 시공, 품질 및 안전관리 등 건설공사 전반에 대하여 스스로 점검하는 자율적이고 상시적인 안전점검 체계가 구축된다. 자율점검현장으로 선정되면 건설사는 자율점검계획을 수립해야 하며, 자체적으로 일일 및 월간점검을 실시해야 하고 분기별로 인근현장과 교차점검 및 본사에서 현장점검을 시행하고 그 결과를 매 반기마다 국토해양부에 제출해야 한다.

우리나라는 국제해사기구에서 제시한 자율수준 3단계의 자율운항선박 기술개발 사업을 추진 중에 있으며, 자율운항선박 및 원격운항센터의 사이버보안에 관한 기술개발이 핵심과제로 포함되어 있다. 국제해사기구는 현존선의 대한 사이버 위협에 대한 조치로 제98차 해사안전위원회에서 '해상 사이버 위험관리 지침(Guidelines on maritime cyber risk management)'을 채택 및 승인하였다. 자율운항선박이 디지털 센서의 거대시스템임을 고려할 때 기술개발 완료시 해상에서 기존 선박과 자율운항선박의 공동 운항을 고려하여 해상교통관제체계(VTS)에 대한 사이버보안 측면을 고려 할 필요가 있다. 이 논문에서는 부산항 VTS 관제사(VTSO)를 대상으로 하여 자율운항선박 운영을 고려한 VTS 관제시스템의 사이버보안 만족도를 조사하였다. VTSO를 대상으로 한 사이버보안 만족도 조사 및 분석방법은 IPA(Importance Performance Analysis) 매트릭스를 적용하였다.
