Conventional studies concerning about economic evaluation of fisheries damages caused by public undertakings have focused on showing the causality between marin environmental variation and fisheries production. But almost all of them have ignored the effect of fisheries damages factors on fisheries price. The study tries to suggest a model how to examine the existence and measurement of the effect of fisheries damage factors on fisheries price using statistical approach, in other words, the estimation of the statistical coincidence between two different population means. The paper tries to give a good application of the model using the case of fisheries damages caused by oil leakage pollution which happened three years ago in the coast of Taean province.

For marine pollution prevention, Korea Coast Guard has enforced the self-check system on excellent workplace of marine facilities and ships since 2007 as part of the government policy for deregulation of administrative inspection. The self-check system had much effect amid interest from the workplaces and with their participation and cooperation. But the system has become stagnant because KCG has missed the proper timing to reflect the social and environmental change, marine workers' consciousness changes and the transformation of its relevant inner organization in the operation of the system for several years. To accommodate the changes of internal and external environments, this study surveyed 332 workers of ships and marine facilities through questionnaire about the self-check system for marine pollution prevention, reflected on the system, and focused on how to improve the existing system effectively. To increase the effect of self-check system, the enhancement of public relations efforts and improvements in marine pollution control system for ships of 5 gross tons and above are necessary. In addition, for relieving the burdens of business activity and visit inspection by KCG on excellent workplaces of ships and marine facilities, Marine Environment Management Act is needed to be amended so that the self-check system can be reflected in its amendment.

This paper desires to assist ensuring of propriety clean-up equipment for clean-up shore or sea of pollution, there is not that responsible ability of a nation has an amount of skimmer or the length of boom. responsible ability of a nation must express overall evaluation what is considering quickly, system, and economizing in addition to an amount or clean-up equipment. responsible ability of a nation is complication and it's mutual relation of each other factor therefore responsible capacity of a nation is expressed using powersim with system dynamics theory.

In recent years, the marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. The prevention of marine accidents has been a major topic in marin society and various policies and countermeasures have been developed, applied to the industries. VTS(Vessel Traffic Services) is considered as one of effective method to promote marine safety but it needs relatively huge amount of budgets to build and also number of personnels for the operation. Thus prior to establishing the VTS. It should be surveyed the marine traffics, general conditions of waterway including geographical, meteorological characteristics and assessed to find the most reasonable area and places for the system. Therefore this paper aims to develop the method for this evaluation through the hierarchical evaluation structure model in connection with ISM(interpretive structural modeling) and AHP(analytic hierarchy process) methods. The model in this paper is applied to 4 coastal area in Korean waterway as candidates and found that the priority for the needs of VTS should be in order such as Yosu, Wando, Mokpo, Geoje coastal area.

In Korea for 20 years(1993-2012), total number and average annual number of oil spills were 6,608 cases and total volume and average annual volume of oils spilt were $57,328k{\ell}$ and nearly $2,866k{\ell}/year$, respectively. The annual number of oil spills and annual amount of oil spilt tended to decrease with the lapse of year in Korea. As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and rage from the biophysical to the social. In this paper, we analysed the emergency response systems and recovery apparatuses for oil spill accident in marine and proposed a developed oil diffusion apparatus which can be used to initial response stage by crew, and to extend golden times. This system can be minimized casualties for rescued people in disaster.

This study evaluated the stability and deformation subsea foundation after implementation of the contaminant isolation method by covering the contaminated materials using Zeolite and sands under subsea condition. The appropriate contaminant adsorption materials used in this study was selected as Zeolite based on the existing research results due to its efficiency. Safety (or stability) was evaluated by calculation and to analyze deformation after completing the contaminant isolation method. The minimum safety factors from slope stability analyses results were 30.1 and 11.2 depending on subsea submerged conditions and the amount of the maximum primary consolidation settlement from consolidation analysis results was 209.2 mm. In addition, change of consolidation amount with increasing consolidation time was evaluated based on consolidation degree.

Recently, environmental problems have been deteriorating rapidly. Therefore, there is an urgent need to establish policies and research in the conservation of the global environment. Many researchers are studied in environment systems to prevent and reduce pollution of water, air and soil actively. In this paper, several parameters such as temperature, humidity, illumination, barometric pressure, dew point, water quality data, and air conditions are collected and transmitted thorough wireless sensor network. The field server is located in the coastal and marine area so that any abrupt changes can be detected quickly. In addition, WSN based flooding routing protocol for efficient data transmission is designed to support and monitor information of climate and marin factors.
