  • Seasonal variability in algal community structure was examined at the intertidal zones of five study sites on the Taean Peninsula, on the western coast of Korea, from February 2014 to November 2015. A total of 118 species of marine algae, comprising 17 green, 24 brown and 77 red algae, were identified. The maximum number of species was observed at the Mohang site (75 species), and the minimum at the Yeonpo site (46 species). The seaweed biomass was $160.24g\;dry\;wt./m^2$ on average, and was maximal at Uihang ($519.04g\;dry\;wt./m^2$) and minimal at Yeonpo ($19.03g\;dry\;wt./m^2$). Based on biomass, the dominant seaweeds at Taean peninsula were Sargassum thunbergii and Corallina pilulifera. Community indices were as follows: richness index (R), 3.21-5.01; evenness index (J'), 0.33-0.38; and diversity index (H'), 0.90-1.12. Based on evaluation of the environmental states by the community indices, the ecological evaluation index (EEI) of Taean peninsula was "moderate". The overall species and biomass of seaweeds decreased after the oil spill. However, Hakampo previously showed a similar algal community structure. In conclusion, the algal community was temporarily affected by the oil spill, but rapidly recovered.

  • The unwanted artificial oil-spill has severely contaminated the coastal environment in the world. Level of contamination has so far been monitered by various indicator species including mussel, oysters, flounder, and cockle. In this study, we decided to use the oyster as a model organism to observe the morphological changes being exposed to the artificial oil-spill in the coastal areas in Taean, Korea. The oysters were collected from four local sites (Sindu-ri, Uiwang-ri, Jonghyeon-dong, Ansan and Uihang-ri) exposed to various levels of pollution after an oil spill in Taean. Microscopic analysis of the hepatopancreatic microstructure in the digestive gland from the collected oysters show that the swelling, whorl, and destruction phenomenon of the nuclear membrane, a well-known microstructure induced by heavy metal exposure, was observed. Nuclear body (Nb), another typical characteristic of contamination or infection were also observed in some samples. Necrosis was observed in tissue samples collected from the area with a high degree of oil pollution. In addition, parasite-like particles (virus, perkinsus) were observed in most samples. Taken together, these results suggest that oil contamination in the oyster habitats influences the cytopathological changes in Crassostrea gigas.

  • Objectives : Our objective was to examine and evaluate the psychological health of the residents of Taean during the cleanup of the Hebei Spirit(HS) oil spill and to review some factors associated with the results. Methods : A community survey of 71 men and women was conducted 8 weeks after the HS oil spill. Questionnaires used were the PWI(Psychological Well-being Index) scale for psychosocial distress, the CES-D(Center for Epidemiologic Studies-Depression) scale for depressive symptoms, and a questionnaire created to assess suicidal impulses. Results : The overall prevalence of high-risk psychosocial distress among the study group was 64.2%. The percentages of respondents with scores on the CES-D Scale above 16 and above 21 were 77.6% and 62.7%, respectively. The percentage of respondents categorized as having suicidal impulses was 18.3%. When compared with unexposed groups in the general population taken from various sources, the residents of Taean were 6.5 times as likely to have high stress and 9.4-9.7 times as likely to be depressed. No significant difference in the rate of suicidal impulse was found between the residents of Taean and the general population. Factors associated with high stress, depression, and suicidal impulses were age, a change in income, educational level, number of days working on the cleanup, and positive responses to questions about "affected daily activity" and "hospital visit due to work on cleanup". Conclusions : The results suggest that the HS oil spill had a significant impact on the psychological health of residents of Taean, but the comparability of the unexposed groups is a limitation of the study.

  • 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.

  • Objectives: This study was conducted to examine the relationship between crude oil exposure and physical symptoms among residents participating in clean-up work associated with the Hebei Spirit oil spill, 2007 in Korea. Methods: A total of 288 residents responded to a questionnaire regarding subjective physical symptoms, sociodemographic characteristics and clean-up activities that occurred between two and eight weeks after the accident. Additionally, the urine of 154 of the respondents was analyzed for metabolites of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) and heavy metals. To compare the urinary levels of exposure biomarkers, the urine of 39 inland residents who were not directly exposed to the oil spill were analyzed. Results: Residents exposed to oil remnants through clean-up work showed associations between physical symptoms and the exposure levels defined in various ways, including days of work, degree of skin contamination, and levels of some urinary exposure biomarkers of VOCs, metabolites and metals, although no major abnormalities in urinary exposure biomarkers were observed. Conclusions: This study provides evidence of a relationship between crude oil exposure and acute human health effects and suggests the need for follow-up to evaluate the exposure status and long-term health effects of clean-up participants.

  • 태안 앞바다에서 발생한 유조선과 예인선 충돌사고로 인해 대량의 유류가 유출되어 주변 연안 해역에 큰 오염피해가 발생하였으며, 유출유 확산과정을 부정확하게 예측한 결과가 제공되어 사고 초기에 효과적으로 피해를 방지하기 위한 대책을 제대로 수립하지 못해서 피해가 커졌다는 주장이 제기되었다. 본 연구에서는 유출유의 확산에 영향을 주는 주요 환경인자가 무엇인지 확인하기 위한 초기 연구로 조류와 취송류에 의한 해수유동이 유출유 확산에 준 영향을 수치모의하였으며, 조류와 취송류가 초기 유출유 확산에 있어서 중요한 요소임을 확인하였다.

  • 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.

  • 본 연구에서는 계층분석과정(AHP)을 이용한 위해도 기반 지역별 기름회수능력 설정 방법을 모델화하여 제시하였으며, 제시된 모델을 적용하여 지역별 기름회수능력을 설정하였다. 모델을 적용하여 설정된 지역별 기름회수능력의 유효성을 확인하기 위해 최대오염사고의 발생이 가능한 지역 중 해상방제장비 동원측면에서 상대적으로 불리한 대산 태안 평택지역에 최대오염사고를 가정하여 각 지역에 배치된 해상방제장비를 동원하여 해상 기름회수작업을 수행하는 시뮬레이션을 실시하였다. 시뮬레이션 결과 사고해역에서 3일 동안 해상에서 회수 가능한 기름의 양은 $15,841k{\ell}$로 계산되었는데, 이는 해상 기름회수 목표량인 $15,000k{\ell}$를 충족시키는 결과로 본 연구에서 제시된 모델이 실행 가능한 것으로 확인되었다.
