"Journal of the Korean Society of Marine Environment & Safety" is representative scientific journal about ocean environment and ocean safety in Korea. This study analyzed research trend of "Journal of the Korean Society of Marine Environment & Safety" through review of articles published in the journals for 10 years tram 2000 to 2009. On the basis of the pursuit of learning and academic constitution of "The Korean Society of Marine Environment & Safety", criteria items of analysis for research trend such as authors institution of employment, region of authors' institution, form of participation in research, article's educational nature, article's method of study, article's area of study, etc. were set up and applied to 310 research articles published in "Journal of the Korean Society of Marine Environment & Safety" for 10 years.

We investigated the temporal and spatial distribution characteristics of chemical oxygen demand (COD) and total organic carbon (TOC) in all 13 locations of Masan Bay from February to November in 2015. The COD and TOC contents were high during the June-August period when the pollution load increased. In particular, the concentrations of COD and TOC were about twice as high in the surface water as in the bottom water. In spatial distribution, the COD and TOC concentrations at the inner bay were about twice as high as those of the outer bay in Masan Bay. As a result of estimating the oxidation efficiency of COD from the surface layer of Masan Bay in 2015 based on the theoretical oxygen demand (TOD), it was at the level of about 23%. Due to the low oxidation efficiency of COD, there is a risk that the organic matter in Masan Bay will be somewhat underestimated. Therefore, for quantitative analysis of organic matter, COD and TOC analyses need to be combined.

The classification of risk factors and the identification of risk acceptance criteria are core works to assess risk levels with high enough confidential level in the field of marine traffic environment. In the previous study work, the twenty kinds of risk factors and its assessment criteria for the domestic marine traffic environment were proposed. In this paper, with these previous studying results, the relative importance of the risk factors were analyzed by questionnaire survey of marine traffic experts using the analytic hierarchy process. The analysis results showed that the relative importance of the visibility restriction is the highest among the twenty kinds of risk factors, and the relative importance of the traffic condition is the highest among the five kinds of risk categories. As results from analysis, it is expected that the approaching method on the relative importance is to be one of basic techniques for the development of risk assessment models in the domestic marine traffic environment.

In order to elucidate temporal variations of temperature, salinity, pH, dissolved oxygen (DO), suspended particulate matter (SPM), dissolved inorganic nutrients, and chlorophyll a, we performed 25-hour continuous monitoring in the Seomjin River Estuary in March (dry season) and July (rainy season) 2006. We also investigated spatial variations of marine environmental parameters across a saline gradient. In the Seomjin River Estuary, continuous monitoring results revealed that salinity variations were mainly affected by tidal cycle in the dry season and by river discharge in the rainy season. In the dry season, the spatio-temporal distribution of dissolved inorganic nutrient (nitrate, nitrite, and silicate) concentrations showed a good correlation with tidal cycle. While nutrient concentrations in rainy season showed not much variance in time. There were 6 and 4 times higher dissolved inorganic nitrogen and phosphorus concentrations in the rainy season than those in the dry season, respectively. Silicate concentration was 43 times higher in the rainy season than that in the dry season. Chlorophyll a concentration was higher in the dry season than that in the rainy season showing high nutrient concentrations. The results of this study, spatio-temporal variations of marine environmental factors are determined by both tidal cycle and river discharge. It seems that chlorophyll a concentration is related to the river discharge than dissolved inorganic nutrient distribution.

Korea actively endeavors to improve the national marine environmental laws and regulations. Along with the growing global concern on the importance of marine environment, the concern is also increasing nationwide in Korea. These institutional changes in Korea have implications in that it has started to internalize the Sustainable Development Principle and the Precautionary Principle in the form of 'law' and 'policy.' The enactment efforts for conservation and sustainable use of marine environment will continue as the legal demand of public for coastal erosion prevention and climate change mitigation increases. This calls for robust revision for more logical framework and coherence of marine environment laws and regulations as well as efficient implementation of policies. In addition, it is strongly required that the systematical research and survey as well as the robust reversion of laws and policies should be taken accordingly for the effective conservation of marine environment.

Korea has experienced a Cochlodinium polykrikoides red tide 10 out of the last 10 years (1993-2002). This species of red tide has been experienced at least once by all the southern coast of the Korean peninsular and has been transported up the southeastern coast all the way to the northeastern coast since 1995. The impression is that red tide is spending and becoming more common not only in the nearest coastal water, but also in the offshore. (omitted)

Chlorobenzenes (CBs) are ubiquitous hydrophobic chlorinated organic compounds in the environment. These compounds are used as de-ordants, solvents and pesticides, as well as byproducts of agro- or petro-chemical related manufacturing processes, such as PCBs and pentachlorophenol, or of biodegradation of lindane (Newhook and Meek, 1994). Unlike some organochlorine (OC) compounds, including polychlorinated biphenyls (PCBs) and various pesticides, CBs are not banned from production or use in any country. (omitted)

Recently, the prediction and analysis technology of marine environment are actively being studied since the ocean resources in the world is taken notice. The prediction of marine disaster by automatic collecting marine environment data and analyzing the collected data can contribute to minimized the damages with respect to marine pollution of oil spill and fisheries damage by red tide blooms and marine environment upsets. However the studies of the marine environment monitoring and analysis system are limited in South Korea. In this paper, we study the marine disasters prediction system model to analyze collection marine information of out sea and near sea. This paper proposes the models for the marine disasters prediction system as communication system model, a marine environment data monitoring system model, prediction and analyzing system model, and situations propagation system model. The red tide prediction model and summarizing and analyzing model is proposed for prediction and analyzing system model.

Marine biotechnology is one of the promising frontier of scientific exploration and commercial utilization for the next century. Compared with the terrestrial environment, the oceans of the world remain largely unexplored and include a major portion of bio-resources. Using the tools of biotechnology, the vast and diverse marine resources can be applied to produce new products and foods. Marine biotechnology has the characteristics of pro-environment, saying energy, and intensive knowledge. Therefore, we can take advantage of the marine biotechnology industry under our situation with the poor natural resources. The study focuses on the current status and administrative supports on marine biotechnology industry for upgrading the economic value of output. The status of our marine biotechnology industry is beginning stage in the economic aspects. Manpower and the level of most technologies are weaker than the ones of the advanced countries. More investment and recruiting skilled specialists are necessary because the improvement of marine biotechnology is depend on the technology and scientists. This study suggests the ways of administrative supports for domestic marine biotechnology: Efficient information network and supporting system for the development of marine biotechnology should be interrelated with other technical and scientific fields; The government should provide sustainable fund for the long-term research project and the infrastructure in the marine biotechnology.
