The purpose of this study is to derive the demands to develop marine science technology to reduce damage of disasters caused by boating accidents. This study analyzed the press release to identify the factors of damages that can result from boating accidents and derive the demands for technology development to approach from the perspective of marine science technology to avoid the elements of damage. For this purpose, this study analyzed the contents of about 77,000 articles posted for a month after the tragedy of the Sewol (April 16 - May 15) to derive the keywords and used SNA for the network analysis of each keyword. The findings of the analysis showed that there were five networks and each network consisted of different aspects of technology development to prepare for the marine disasters. Based on these findings, this study derived the demands for technology development from the perspective of marine science technology required to prepare for the possible marine disasters caused by vessels in the future.

최근 세계적으로 바다가 자원의 보고로 주목 받으면서 해양 환경 분석 및 예측 기술에 대한 연구가 활발히 진행 되고 있다. 자동화된 해양 환경 자료의 수집과 수집된 자료를 분석하여서 해양재해를 예측하면 기름 유출에 의한 해양오염의 피해, 적조에 의한 수산업의 피해, 해양환경 이변에 의한 수산업 및 재해 피해를 최소화하는데 기여할 수 있다. 그러나 국내 해양 환경에 대한 조사 및 분석 연구는 제한적이다. 본 논문은 국내의 원해 및 근 해역에서 수집된 해양 환경 자료를 분석하여 해양재해를 예측할 수 있는 시스템 모델을 연구한다. 이를 위해서 본 논문에서는 해양재해 예측 시스템을 위해서 통신시스템 모델, 해양환경 자료 수집 시스템 모델, 예측분석 시스템 모델, 상황전파시스템에 대한 모델을 제시하였다. 또한 예측분석 시스템을 위한 적조 예측 모델과 요약분석 모델을 제시하였다.

In the present paper, the analysis is on the safe navigation between ships moving each other in restricted waterways under the external force, such as wind or current The numerical simulation of manoeuvring motion was carried out to propose an appropriate safe speed and distance between ships, which is required to avoid marine disasters from the viewpoint of marine safety. From the inspection q this investigation, it indicates the following result In case of proximal navigation between ships under the wind and current, the low-speed vessel is potentially hazardous because the rudder force if low-speed vessel needed for steady-state course-keeping is not sufficient, compared to the high-speed vessel The manoeuvring characteristic based on this investigation will be very useful for keeping the safety of navigation from the practical point of ships design and traffic control in restricted waterways.

해안가 복합재해는 기후변화로 인한 해수면상승과 집중호우, 태풍, 해일 등으로 인한 내·외수침수와 범람이 복합적으로 발생하는 것으로 최근 발생빈도와 피해규모가 커지고 있다. 본 연구에서는 해안가 복합재해를 관리하는 법과 제도 현황을 검토하고 이를 관리하고 예방하는 개선방향을 도출하고자 한다. 이를 위해 현행 우리나라 법률 중에서 해안가 자연재해 관리를 위해 지정하는 지구·구역 제도를 중심으로 재난 및 안전관리기본법, 자연재해대책법, 국토계획법, 연안관리법, 하천법, 하수도법 등을 검토하였다. 이를 통해 법률의 목적과 성격, 공간적 범위, 관리수단 등을 비교한 결과 자연재해대책법을 토대로 해안가 복합재해를 통합적으로 관리하는 것이 바람직하다고 판단하였다. 현재 제도의 한계점을 극복하고 구체적인 법률 및 제도 개선방안을 도출하기 위해서 자연재해 관련 전문가들을 대상으로 세부 요소에 대한 설문조사를 실시하였다. 그 결과 해안가 복합재해관리를 위해 현제도를 개선하거나 새로운 제도 도입이 필요하며, 행정안전부, 환경부, 국토교통부, 해양수산부 등 부처 통합적인 의사결정 거버넌스 설치 운영을 통해 육상과 해역을 통합적으로 관리할 필요가 있는 것으로 나타났다.

본 연구는 경제성자의 급속한 발전으로 말미암아 해상에서의 수송물량이 증가함으로 인하여, 해상에서 크고 작은 해난사고가 많이 발생하고 있는바, 이에 따른 안전관리 체계의 중요성이 한층 고조되고 있다. 특히 안전관리 체계를 수립함으로서 인명과 재해를 방지할 수 있고, 국가적인 차원에서 철저한 안전사고 예방 및 구조에 관한 관리조직의 제도적 해상안전통신망 시스템을 연구 하고자 한다.

The purpose of Maritime Safety Tribunal is that experts about ship operation investigate and reveal causes of marine disasters and suggest plans to prevent recurrence in Korean Maritime Safety Tribunal which is a kind of administrative court. Despite the fact that 72% of marine disasters is fishing vessel accidents and 75% of collision accidents between vessels which most occur is related to fishing boats, it is the very serious problem that there is no any person with licenses of marine technicians for fishing vessels in judges and investigators of Korean Maritime Safety Tribunal. The operational characteristics of fishing vessels, their sizes, and shift patterns of duties in wheelhouses are completely and incommensurably different from those of merchant vessels. By the way, if the investigators and judges who just consist of merchant vessel experts investigate and judge marine accidents about fishing vessels, there could be errors in establishment of policies to investigate and reveal their causes and prevent recurrence of accidents. Especially, in case of collision accidents between fishing vessels and merchant vessels, it is thought that the marine accident interested provides causes which can be doubtful about fairness of judges. Therefore, it is thought that the ratio of judges and investigators is most desirable to compose it to be similar to the occurrence frequency of marine accidents. For this, the following solution plans are suggested. First, qualification for appointment requires first class marine technicians. But there is the only one vessel which needs the first class in fishing vessels. Therefore, it is thought that the provisory clause should be added so that the second class marine technicians can be used instead of the first class ones. Second, the marine accidents of fishing vessels reach 72% but the fact that there is no any judge and investigator with licenses of marine technicians for fishing vessels is thought to go against the purpose of establishment of Korean Maritime Safety Tribunal. Therefore, it is thought that there is, at least, one more judges and investigators in the central and local Korean Maritime Safety Tribunals. The same method should be applied to judge assistants and investigation assistants.

Various types of coastal structures have been constructed to prevent coastal disasters. Among these coastal structures, submerged breakwaters have been used more widely than all of the other coastal structures because of their excellent advantages in scenery effects, construction efficiency, and environmental benefits. This study investigated the potential of the horizontal plate submerged breakwater model. Usually, it is necessary for a submerged breakwater to minimize and compensate for the negative impacts on the marine environment and ecosystem caused by the marine construction. Thus, the prevention of coastal disasters was verified for this submerged breakwater model, regardless of its function as a fish reef. The purpose of this study was to investigate the hydraulic characteristics with changes in the crest width and porosity of a horizontal plate submerged breakwater and compare the results of this study with the results of other studies on permeable and impermeable submerged breakwaters.

Recently, EI nino and La nina phenomena have known as a cause of the unusual weather and meterological disasters in the world. The meteorological disasters in Korea have mainly caused by typhoons. In this paper, we studied the relationship between EI Nino and La Nina phenomena and the number of typhoons which have affected on Korea using the long-term data for the period from 1940 to 1999 (60 years) in case of normal years, EI Nino years and La Nina years, the numbers of typhoons which have affected on Korea are 3.1/year, 2.7/year and 3.9/year respectively. The number of typhoons which have affected on Korea in La Nina years is more than those in EI Nino years and normal years The occurrence rate of typhoon in La Nina years is also higher than those in EI Nino years and normal years.
