호안을 보호하기 위해 테트라포드(TTP)로 대표되는 소파블록이 항만, 어촌 어항지역 등 해안 전역에 걸쳐 사용되고 있다. 하지만 친수활동의 증가로 테트라포드에서의 해안안전사고가 증가하고 있으며, 테트라포드가 가지는 형태적, 색상적 특성으로 인해 안전, 경관, 환경 측면에서 심각한 문제를 일으키고 있어 보다 안전한 친수활동 공간을 제공할 수 있으며 해안경관을 향상시킬 수 있는 소파블록 디자인 개발이 시급하다. 따라서 본 연구에서는 현재 사용되고 있는 소파블록의 문제점을 분석하고 국내외 기술개발 현황을 바탕으로 소파블록 디자인 개선사항을 제시하였다.

Purpose: The Taean oil spill in 2007 taught us a great lesson and is a representative example of a social disaster. It was overcome through the dazzling dedication and service of volunteers. However, behind the volunteers, they were directly or indirectly exposed to the spilled oil, resulting in health problems such as headaches and safety accidents. Safety accidents were caused by unsafe behavior, and unsafe behavior was caused by lack of safety awareness or ignorance. We want to find an education and training program to systematically raise safety awareness for volunteers in connection with the Occupational Safety and Health Act. Method: The occupational safety and health law, the laws related to coastal clean-up, and the unsafe behavior factors in the statistics of occupational accidents in the past year were mainly identified. Result: The contents of education and training hours to be provided for volunteers involved in coastal clean-up were presented in comparison with workers under the Occupational Safety and Health Act. Conclusion: Safety and health education for volunteers and volunteer managers is directly related to safety awareness and can prevent unsafe behavior.

항만의 수출입 물동량 증가와 해양 레저 활동 증가로 해안에서 빈번하게 발생되는 해양사고는 재산과 인명피해는 물론 해양환경 파괴문제까지 대두되어 심각한 문제를 야기시키고 있다. 최근 필리핀 해역에서 발생한 미 7함대 소속 소해함 MCM-5 Guardian 함의 좌초사고를 통해 해양사고가 발생할 수 있는 원인과 항해 시 발생될 수 있는 오차요인인 좌표체계, 전자해도, 항법오차 등의 문제점을 분석하여 항해안전을 위한 대책방안을 제시하였다.

Recently, due to increased tourism and leisure activities, falls by fishers from coastal wave-dissipating blocks (breakwaters) in Korea have been rising. We investigated the optimal mesh size for use in safety nets designed to cover Tetrapod (TTP) breakwaters to prevent casualties from falls. This is a prerequisite for considering the scale and economics of safety net facilities. The optimal mesh size was determined based on the fisher gender and age, and the bodily features of Koreans. The optimal mesh size was found to be 18.6-27.0 cm, derived based on the femoral length and chest circumference.

Coastal safety accidents are characterized by a high proportion of human negligence and repeated occurrences of accidents caused by the same factors. The Korea Coast Guard prepares and implements various countermeasures to prevent accidents at coastal safety accident sites. However, there is a shortage of safety facilities and safety management personnel according to the limited budget. In addition, the ability to be proactively and proactively respond is low due to the limitations of the coastal safety accident risk forecasting system, which relies on the meteorological warning of the Korea Meteorological Administration. In this study, as part of preparing the foundation for establishing a preemptive and active coastal safety management system that can manage accident-causing factors, predict and evaluate risk, and implement response and mitigation measures after an accident occurs before coastal safety accidents occur. The establishment of a risk assessment system was proposed. The main evaluation factors and indicators for risk assessment were established through the analysis of the status of coastal safety accidents. The risk assessment methodology was applied to 40 major hazardous areas designated and managed by the Korea Coast Guard.

The importance of marine pollution prevention is increasing day by day both at home and overseas. Against this context, this study proposes policy directions to forge an improved system of coastal control for local governments. I have analyzed the coastal pollution response capacity of local governments to find out how the central government can better support these efforts to reinforce capacity. For the purposes of this research, I carried out a number of case studies on large-scale marine pollution accidents that occurred at home and abroad. According to the results, I identified the implications of the coastal pollution response capacity of local governments and suggested several alternatives such as construction of step by step response system, strengthening education and training, part of human network activation, establishment of grounds for securing response resources, and establishment of dedicated department to prepare for potential future marine pollution accidents. However, as little research has been done on the coastal pollution response capacity of local governments, this work may be regarded as an experimental study to help facilitate follow-up research in the future.

This study was carried out for the purpose of proposing the guideline for the non-mischief and comfortable coastal leisure activities to reduce the marine pollution caused by sea fishing and strengthen the marine management and supervision for the fishing activity. In research method, a extensive reference was examined and analyzed, and the questionnaire investigation and field work were carried out to recognize the present conditions and problems concerning the environmental pollution caused by sea fishing. At the same time, the guideline for the safe and comfortable activities was proposed by diagnosing of actual evil conditions of marine environment due to the sea fishing activity and by analyzing of foreign mangement cases. On the basis of these research results, it is useful to contrive a management criteria for the realities investigation on the pollution of coastal activities. It also contributes to develop the regional economy by controlling coastal leisure activities effectively and systematically through the national publicity for the prevention of marine pollution.

해양사고 예방에 대해 연안 해역이 취약함에 착안하여 서남해안을 중심으로 연안 해상교통관제서비스(연안VTS) 시스템이 설치되고 있다. 인천, 평택, 대산항이 밀집되어 있는 경인 지역은 복잡한 해안 구조와 교통량이 많아 허베이스피리트호 사건과 같이 대형 해양사고에 취약한 지역으로서 안전관리를 위해 경인 연안VTS가 2017년 개국될 예정이다. 관제서비스 제공의 품질을 향상하기 위하여, 경인 연안VTS 관제구역을 설정해 보고, 교통여건, 해상교통량, 해상교통흐름 및 해양사고 현황을 조사하여 항행 위해 요소를 분석해 보았다.

인공 지능 분야에서 특히 퍼지와 같은 기술은 전반적인 산업 자동화에 많이 사용되어 왔다. 퍼지 제어는 인간의 추론 과정을 모델링한 기술로서 인간에 유사한 결정 능력과 복잡하고 다양한 환경에 매우 효과적이다. 본 논문은 이러한 퍼지 제어의 장점을 연근해의 선박 자동 항해에 적용시켜 보았다. 심해에서는 공간상의 제약이 없기 때문에 선박의 자동항해는 원하는 목표지점까지 안전하게 운항할 수 있지만, 연근해안에는 심해와 달리 각종 장애물들(작고 큰 섬들과 해안, 연근해에 작업중인 선박들)이 있으며 이것들로 인한 충돌사고가 종종 발생하고 있는 실정이다. 그러므로 연근해안에서 보다 안전하고 자율적인 항해를 위해 인공 지능 기술인 퍼지 기술을 선박에 적용시켰다. 본 논문에서 제안된 다변수 퍼지 시스템을 2개의 서로 다른 동적 환경을 가지는 지형에 적용시켜 보았고, 그에 따른 실험들을 수행했을 때, 만족할만한 결과를 얻을 수 있었다. 따라서, 본 논문에서 제안된 다변수 퍼지 제어시스템을 이용한 선박이 동적인 환경에서도 스스로 장애물을 인식하고 회피함으로 안전하게 연근해를 운항할 수 있음을 보였다.

해양유류오염사고 유출유 피해 위험도 산정을 위한 평가기법을 연구하였다. 본 연구의 위해도 평가에서는 과거 사고 사례에 근거하여 선정한 사고 해역에 대하여 여러 경우의 유출유 확산을 계산하고, 계산 결과를 통계 분석하여 유출유의 피해 가능성, 도달시간, 피해 규모 둥을 산정한다. 유출유의 피해 가능성, 도달시간, 피해규모는 환경민감자원 현황에 근거한 해역별 해안 및 어장 양식장을 대상으로 산정하며, 각 해역별 피해 정도를 비교함으로써 해역별 위해도를 산정한다. 이러한 결과는 특정 유류오염사고에 대한 보다 객관적이고 종합적인 피해 위험을 제시할 수 있으며, 실시간 피해 위험 예측과 연계하여 보다 타당성 있는 유류오염사고 위해도 평가 결과를 제시할 수 있다.
