  • Oil spill accidents at sea result in a wide range of damages, including the destruction of ocean environments and ecosystems, as well as human illnesses by the generation of harmful gases caused by phase changes in crude oil. When an oil spill occurs, an immediate initial action should be performed to minimize the potential damage. Existing studies have attempted to identify crude oil spillage by calculating the crude oil spill range using synthetic aperture radar (SAR) satellite images. However, SAR cannot capture rapidly evolving events because of its low acquisition frequency. Herein, an algorithm for estimating an oil spill area from an image obtained using a digital camera is proposed. Noise that may occur in the image when it is captured is first eliminated by preprocessing, and then the image is analyzed. After analyzing the characteristics of the digital image, a strategy to binarize an image using the color, saturation, or lightness contained in it is adopted. It is found that the oil spill area can be readily estimated from a digital image, allowing for a faster analysis than any conventional method. The usefulness of the oil spill area measurement was confirmed by applying the developed algorithm to various oil spill images.

  • There has been increasing offshore oil exploration, drilling, and production activities, as well as a huge amount of petroleum being transported by tankers and pipelines through the ocean and costal environment. Assessment must be made of the potential risk of damage resulting from the exploration, development and transportation activities. This is achieved through predictive impact evaluations of the fate of hypothetical or real oil spills. VVhen an oil spill occurs, planning and execution of cleanup measures also require the capability to forecast the short-term and long-term behavior of the spilled oil. A great amount of effort has been spent by government agencies, oil industries, and researchers over the past decade to develop more realistic models for oil spills. Numerous oil spill models have been developed and applied, most of which attempt to predict the oil spill fate and behavior. For an actual contingency planning, the oil fate and behavior model should be combined with an oil spill incident model, an environmental impact and risk model and a contingency planning model. The purpose of this review study is to give an overview of existing oil spill models that deal with the physical, chemical, biological, and socia-economical aspects of the incident, fate, and environmental impact of oil spills. After reviewing the existing models, future research needs are suggested. In the study, available oil spill models are separated into oil spill incident, oil spill fate and behavior, environmental impact and risk, and contingency planning models. The processes of the oil spill fate and behavior are reviewed in detail and the characteristics of existing oil spill fate and behavior models are examined and classified so that an ideal model may be identified. Finally, future research needs are discussed.

  • A sunken ship often involves an oil spill. This paper was carried out to minimize environmental and cost damages stemming from oil spil of sunken shipl. Through the analysis of both the standards of the oil tank system and installation, we have identified potential oil spill sites and proposed a remedy of prevention. The result of study, the air pipes of the oil tank are a vulnerable point for oil spill. Also, the remote control devices of emergency shut-off valve have poor accessibility at abandon ship, making it difficult to shut off the emergency shut-off valve. Thus, we propose the addition of a remote quick closing valve in the air pipe and the building of a central control system.

  • Oil spills have occurred throughout the years of industrialization and represent a global challenge as they affect vast areas of the ocean. The toxicity of crude oil to aquatic organisms has been extensively investigated, but the potential impacts of crude oil on vertebrate development remain largely unknown. Here, we investigated the effects of dispersants used in treating a recent oil spill, as well as that of crude oil, on vertebrates by using the zebrafish (Danio rerio) model species, which has been widely used in empirical studies of both early embryonic development and adult physiology. Chronic exposure to crude oil resulted in marked developmental abnormalities, including pericardial edema, abnormal trunk vessel development, retardation of axonal branching, and abnormal jaw development. Embryonic development was affected more severely by exposure to the oil-dispersant combination than to the oil alone. Thus, the zebrafish in vivo model system suggests that dispersant treatment can have detrimental developmental effects on vertebrates and its potential impact on marine life, as well as humans, should be carefully considered in clean-up efforts at the site of an oil spill.

  • 본 논문에서는 2007년 12월 7일에 발생한 태안만 원유유출사건에 대한 관련 산업의 시장반응을 조사하였다. 태안사고는 국내의 조선업, 원유산업에 대해 환경관련 규제의 강화를 초래할 것이라는 우려를 낳았고 환경산업에 대해서는 환경복구와 관련한 수익의 기회를 제공하였다. 사회적 비난의 고조 및 규제강화의 전망은 조선업과 원유산업의 주가는 하락시키고 수혜산업의 주가는 상승시키는 동인으로 작용하였다. 태안원유유출사고는 이중선체 유조선 의무화 조치의 발효를 앞당기는 계기가 되어 국내 선박제조업에 호재로 작용하기도 하였다. 이에 따라 사고 직후 하락하던 조선업의 주가는 규제발효 이후 반전하여 지속적인 양의 추세를 유지하였다. 개별기업에 대한 분석에서 환경공시의 수준이 양호한 기업은 그렇지 않은 기업에 비해 부정적인 시장반응이 완화되는 경향이 관찰되었다.

  • 홍수, 지진, 폭설 등과 같은 자연재해나 대형사고 등에 대한 언론의 보도양태에 대한 분석연구들은 국내외를 막론하고 많이 이루어지지 못했다. 이러한 재난은 거의 매년 끊임없이 발생하고, 이에 대한 보도와 그에 대한 비판이 계속되었음에도 불구하고, 이러한 보도방식에 대한 학문적 비판과 대안이 미흡했다는 것은 큰 문제점이라고 할 수 있다. 이러한 맥락에서, 본 연구에서는 2007년 12일 충남 태안군에서 발생한 허베이 스피리트호 기름유출 사고에 대한 대응 및 복구과정에서 한국의 언론보도가 재난관리 과정상 제대로 역할을 수행했는지를 분석해 보고, 아울러 개선방안을 제시하였다. 허베이 스피리트호 기름유출사고를 통해 본 우리 나라의 재난보도의 문제점을 요약해 보면, 먼저 부정확한 보도가 다수 발생하여 피해자인 태안주민들을 더욱 곤경에 빠뜨리는 오류를 범하였다는 점이다. 또한, 사건 초기에 기름유출사고에 대한 잘못된 이름 짓기가 있었고, 재난보도의 근간이 피해자 중심이 아닌 독자 중심의 보도로 일관하였다는 점이다. 끝으로, 자원봉사에 대한 과잉보도로 인해 정작 사건의 본질과 피해당사자의 구호 등은 취재 및 보도에서 밀리는 현상이 초래되었다. 향후 재난보도는 피해자 중심의 보도, 방재 및 문제해결 보도 등의 취재를 지향하고, 아울러 재난전문 기자를 양성해야 한다.

  • China, Japan and Korea are the world's top 10 energy consumers, and so very interested in the development of seabed hydrocarbon resources in order to meet their energy demands. The East China Sea is the tri-junction area where three countries' entitlements on the maritime boundaries are overlapped. There are abundant oil reserves in the East China Sea, and therefore competitions among countries are growing to get control of them. Although these countries have concluded the bilateral agreements to jointly develop resources in the East China Sea, they do not function as well. Because joint development and management of seabed petroleum resources can lead to stable development system, and to lower possibility of legal and political disputes, the needs for joint development agreement among three countries are urgent. Meanwhile, Northeast Asian seas are semi-closed seas, which are geographically closed and vulnerable to marine pollution. Moreover there are a lot of nuclear power plants in coastal area, and seabed petroleum resources are being developed. So it is likely to occur nuclear and oil spill accidents. Fukushima nuclear disaster and Bohai Bay oil spill accident in 2011 are the cases to exhibit the potential of major marine pollution accidents in this area. It is anticipated that the risks become higher because power plants and offshore oil platforms are extending gradually. Therefore, the ways to seek the joint marine environmental protection agreement focused on regulation of nuclear power plant and offshore oil platform have to be considered. In this paper, we try to find the way to make joint development and joint environmental protection agreement in Northeast Asian seas. We concentrate on the measure to drive joint development of seabed petroleum deposits in East China Sea's overlap area, despite of maritime delimitation and territorial disputes, and we try to drive joint marine environmental protection system to respond to marine pollution and accidents due to offshore oil platform and nuclear power plants. Through these consideration, we seek solutions to deal with lack of energy, disputes of maritime territorial and boundary delimitation, and marine pollution in Northeast Asia.
