Due to an oil spill accident occurred in Taean coastal zone wide range of coastal waters were polluted. Inaccurate prediction of spilled oil trajectory is known as a cause that has increased the pollution damage in the beginning stage. In this study, a numerical modeling of spilled oil dispersion has been conducted to know which physical factors caused the severe and wide pollution. Especially the simulation is focused on how to model hydrodynamic circulation accurately. The simulation results showed that the hydrodynamic flow is very important in predicting oil fate, specially, in the short-term dispersion of spilled oil.

Objectives: On December 7, 2007, the Hebei Spirit oil tanker spilled out 12,547 kl of crude oil on the Yellow Sea 10 km away from the cost of Taean Province, Korea. As the coastline has been contaminated, local residents have been exposed to crude oil. Because the residents were showing many symptoms, we investigated the acute health effects of this oil spill on them. Methods: We conducted a cross-sectional study consisting of the heavy and moderately oil soaked area in Taean and the lightly oil soaked area in Seocheon. Ten seashore villages were selected from each area, and 10 male and female adults were selected from each village. We interviewed the subjects using a structured questionnaire on the characteristics of residents, the cleanup activities, the perception of oil hazard, depression and anxiety, and the physical symptoms. The odds ratios and 95% confidence intervals were analyzed using logistic regression analysis. The logistic regression model was adjusted for age, gender, education, smoking, the perception of oil hazard and anxiousness. Results: The more highly contaminated the area, the more likely it was for residents to be engaged in cleanup activities and have a greater chance of exposure to oil. The indexes of anxiety and depression were higher in the heavy and moderately oil soaked areas. The increased risks of headache, nausea, dizziness, fatigue, tingling of limb, hot flushing, sore throat, cough, runny nose, shortness of breath, itchy skin, rash, and sore eyes were significant. Conclusions: The results suggest that exposure to crude oil is associated with various acute physical symptoms. Long-term investigation is required to monitor the residents' health.

Approximately 250 marine pollution accidents involving oil and HNS spills are reported every year in the Republic of Korea. It is necessary that a strengthen of specialization of marine pollution response personnel on marine pollution response due to a diminution of damage when a major oil and HNS spill incident occurred, as in the case of the M/V Heibei Spirit and the M/V Maritime Maisie. In regard to this, the International Maritime Organization (IMO) has planned to revise the OPRC Model Training Course to strengthen expertise for oil spill incident responses. Through a comparison of curriculum with the Korea Coast Guard Academy (KCGA) program, a revised IMO Model Course and the OSRL training institute, this study recommends the following improvements for the education program of the KCGA in response to oil spills. This study suggests several options in line with this approach to revise the oil spill response education curriculum, exercise, discussions and making materials. Accreditation of the KCGA as an institute that provides an IMO Model training course developed according to the revised IMO Model Course material is proposed.

Increase of marine transpotation in coastal area frequently yields oil spill accidents due to collision or grounding of oil tankers, which affects great deal of damages on ocean environments. Exact prediction of oil pollution area in time domain, which is called oil map, is very important for effective and efficient oil recovery and minimization of environmental damage. The prediction is carried out by considering the two distinct processes which are initial diffusion on the still water surface and advection due to tide, wind wave induced surface currents. In the present paper, only the initial diffusion is dealt with. Somewhat new simulation model and its numerical scheme are proposed to predict it. Simple diffusion experiment is also carried out to check the validity of the present method. Furthermore, some example simulations are performed for virtual oil spill accident. Quite realistic oil map including oil thickness distributions can be obtained by the present model.

In this study we examined the economic value of restoration technology for oil spill using contingent value methods. One and one half approach to questionnaires can be taken when analyzing tax payer situations as well as single bound approach. The results of the empirical analysis suggest three conclusions. First, the economic value of the restoration technology considered are estimated to be between 8,439 won to 11,867 won per month. Second, the WTP is estimated differently depending on the approaches, OOHB and SB, and the degrees of difference are very sensitive to the model specifications. This empirical result supports the argument for using interval for the economic value when using CVM. Third, the empirical results may provide useful input to policy authorities attempting to estimate the economic justification of the R&D investment for developing an ocean environmental restoration technology.

Objectives: We aimed to assess the risk of metabolic syndrome one year after the 2007 Hebei Spirit oil spill in Taean, Korea among people exposed to spilt oil during clean-up work. Methods: A total of 6,923 adults, including 3,019 males and 3,904 females, participated in the study. Health examinations and blood tests (total cholesterol, triglycerides, HDL, fasting blood sugar) were performed. A logistic regression model adjusting for age, gender, smoking history, drinking history, income, education, and marital status was used to estimate the risk of metabolic syndrome associated with the level of oil spill exposure. Results: The prevalence of metabolic syndrome was 24.9% among males and 18% among females. Compared with people living within 20 km of the coastline, the risk of metabolic syndrome among people living within 0.8 km of the coastline was significantly higher (male OR=1.696, 95% CI=1.320-2.178, female OR=1.992, 95% CI=1.549-2.561), including a significant dose-response relationship for distance from early contaminate coastline (p<0.001). The risk of metabolic syndrome was higher according to the increase of duration of cleaning work. The risk of metabolic syndrome among people who participated in the clean-up work for more than 116 days, compared with people who participated in the cleaning work for or less 14 days, was significantly higher (male OR=1.845, 95% CI=1.448-2.353, female OR=1.752, CI=1.378-2.228), with a significant dose-response relationship for days of clean-up work (p<0.001). Conclusion: This study showed that there is a significant association between exposure to the oil spill during the clean-up work, distance from early contaminate coastline and the risk of metabolic syndrome in a doseresponse manner.

A simulation model and its numerical algorithm for the prediction of time-varying oil pollution region are proposed. Not only forces inducing molecular diffusion of oil but also oil advection due to the ocean surface current are considered in the present unified model Furthermore, an automatic modulation of computational grid is introduced to achieve more practical and effective numerical scheme. Applying the present method to some assumed oil spill cases, quite realistic oil maps are thought to be obtained.

A three-dimensional digital image processing technique is proposed to quantitatively predict the dispersion phenomena of oil droplet onto the surface of the water. This technique is able to get the dispersion rate of an oil droplet three-dimensionally just below the surface of the water over time. The obtained dispersion rate obtained through this technique is informative to the investigation into the relationship among the gravity, surface tensions between oil, water, and air. This technique is based upon the three-dimensional PIV(Particle Imaging Velocimetry) technique and its system mainly consists of a three CCD(Charge Coupled Device) cameras, an image grabber, and a host computer in which an image processing algorithm is adopted for the acquisition of dispersion rate oil an oil droplet.
