Tankers have somewhat different shapes in construction and working condition compared with normal merchant ship. If an accident occurs, normal merchant ship's damages will mostly be confined to ship and cargo, but those of tankers will result in oil spills and catastrophic loss beyond our imagination. So, first we must understand risk factors, pre-loss control and post-loss control, legal regulations about its indemnification and marine insurance for oil tanker operation. When unexpected accidents happen, despite pre-loss control, it is possible to cover those kinds of losses by insurance. To control these losses, however, it is important to establish compensation for oil pollution and arrange for oil pollution preventing system. In spite of these oil pollution preventing systems, we have rarely seen that pollution from oil tankers could be solved. So this paper was studied more fundamental and overall control measures for the risk management of oil tanker operation.

The purpose of this study is to estimate air purification effectiveness considering the improvement of its methods related atmospheric environment. The air purification effectiveness is estimated in Daegu, one out of Korean Metropolitan cities because air pollution is getting serious in a heavily urbanized area. The absorption of pollutants is calculated by considering spatial heterogeneity that was not considered previous studies and the spatial resolution of air dispersion modeling is also improved by kriging method. According to the type and distribution of urban forest, total 26 kinds of plant communities were distributed with Pinus densiflora community, Pinus densiflora-Quercus mongolica community, Pinus densiflora-Quercus acutissima community and other kinds of communities in the study area. In the results of estimating the $CO_2$ absorption amount for identification of the air purification effectiveness on urban forest, the annual absorption amount was total 108,155t/yr. Also, the annual absorption amounts of $NO_2$ and $SO_2$ were total 183.5 ton and 410.2 ton respectively. The findings from this study can confirm the differences of pollutant absorption by concentration that could not identify if spatial distribution of pollutant concentration had not been considered.

That occur in the ocean and the efficient management of marine litter on marine pollution oil spill response one step further strategies are needed. Marine pollution accidents occurred in 2011, a total of 287 and was found in runoff 369 kL, respectively compared to the previous year decreased by 13% and 39%. Average amount of marine materials during 5-years represent the oil flow of 310.5 kL (heavy fuel oil of 106.0 kL, diesel of 178.9 kL, oily bilge water of 22.3 kL, other oil of 7.7 kL) and the waste of 62.3 tons, the hazardous and noxious substances (HNS) was 510.6 kL. Marine emissions in 2011 by type of waste that a total amount of dumping 3,972 $m^3$, and livestock manure 795 $m^3$(20%), waste water 1,431 $m^3$(36%), sewage sludge 887 $m^3$(22%), wastewater sludge, 813 $m^3$(21%), manure 5 $m^3$(0.1%), other 41 $m^3$(0.9%), respectively. The concept of marine waste and needs to be more clearly defined. Integrated management of hazardous chemicals according to the incident management system should be established. To remove of coastal pollution, response officer needs korean coast response system. Like the marine pollution response, coastal pollution response systems also require step response.

The purpose of this study is to develop a Water Quality Management System(WQMS), which calculates pollutant discharge and forecasts water quality with a water pollution model. Operational water quality management requires not only controlling pollutants but acquiring and managing exact information. A GIS software, ArcView 3.1 was used to enter or edit geographic data and attribute data, and Avenue Script was used to customize the user interface. PCI, a remote sensing software, was used to derive land cover classification from 20 m resolution SPOT data by image processing. WQMS has two subsystems, database subsystem and modelling subsystem. The database subsystem consisted of watershed data from digital maps, remote sensing data, government reports, census data and so on. The modelling subsystem consisted of NSPLM(NonStorm Pollutant Load Model) and SPLM(Storm Pollutant Load Model). It calculates the amount of pollutant and predicts water quality. These two subsystems were connected through a graphic display module. This system has been calibrated for and applied to Mokhyun Stream watershed.

Air pollution associated with the SOx emission from the shipboard propulsion and generation engines is becoming one of the major environmental concerns these days. Lead by the international organizations including IMO and European Union, a significantly strengthened air pollution related regulations have been introduced and they are becoming in practice as scheduled. Such rules are basically giving the guidelines for permissible SOx emission which can be only met by using high quality fuel oils with less sulfur content or operating scrubbing systems aiming at reducing SOx at the engine exhaust. Since both countermeasures can lead to the cost increase in ship building and operation, Korean shipbuilding industries, leading the world's market, need to be well aware of the ever changing regulations and be prepared with proper solutions. Here, we briefly summarize such latest rules and regulations on the air pollution at sea, and review some technical issues on the scrubbing systems available with some suggestions.

Due to the natural increase of human population and the concentration of industrial complexes to coastal area, the uses of nearshore area were increased drastically, and the tendency will not stop for a while. Therefore, the loss of human life and property damages of the present days for a disaster of the same magnitude should be heavy as compared to those of the past. For the better utilization of the sea and the prevention of the frequent marine natural and man-made disaster, and for the preparedness for the ocean pollutions, through ocean researches are required. the circulation, tidal currents, storm surges, sea surface wind, waves and sea fogs of the Yellow Sea should be investigated first from the oceanographic point of view, and then the dispersion and diffusion of spilled oil and pollutants, beach erosion, red tide, and longterm sea level oscillations can be studied. International cooperation is crucial for the investigation of the sea because of the temporal and geographic scales of the oceanic phenomina.

Indoor air pollution has been a critical issue as a new environmental problem and a significant amount of research has been performed on the indoor air pollution in buildings as well us those in mean of transport such as automobiles, subways, and buses. The actual condition of indoor air pollution in ships, however, was not investigated. Because airtightness of a ship is very higher than a general building and the crew spend almost all the time in indoor space of the ship during underway, indoor air quality(IAQ) of the ship is very important for their comfortableness and health. In this paper, indoor air quality of a new ship is measured and analyzed for the improvement of IAQ in ships.

The purpose of this study was to analyze the risk and vulnerability of marine accidents based on statistical data on marine accidents at Ulsan Port, which has the largest amount of liquid cargo in Korea. It was found to be quite vulnerable to the risk of marine accidents, environmental damage, and vulnerability to environmental pollution accidents. Based on analysis results, marine accident scenarios and accident response strategies were prepared. Additionally, as a response strategy to prepare for large-scale marine pollution accidents at Ulsan Port, it is necessary to establish control equipment and infrastructure, as well as establish a control center to integrate marine accident safety functions. In particular, in the case of liquid cargo specialized ports such as Ulsan Port, considering the size of the cargo volume and the frequency of marine pollution accidents, it is urgent to build professional safety management institutions, which should make the port safer.

해상 교통 안전을 향상하고 선박 사고를 사전에 방지하기 위해서 선박 사고에 대한 위험도 평가가 선행되어야한다. 선박의 위험도에 대한 개념은 여러 가지로 정의되고 있는데, 본 연구에서는 데이터베이스를 기반으로 사고 발생 가능성과 피해를 예측하여 위험지수를 산출하는 위험도 평가 방법에 대해 고찰해보았다. 사고 발생에 따른 인명 손실과 오염 규모 등의 피해 결과에 따라 고위험 선박이 선별될 수 있으며, 선박의 위험도의 정량적 기준은 사고 발생 확률과 사고 결과의 심각성으로 결정된다. 대량의 데이터베이스를 통계적으로 분석하여 위험도를 도출하기 위해서는 데이터베이스의 확보 뿐 아니라 데이터베이스의 구조화가 기반이 되어야 한다. 또한 과거 자료에 입각한 데이터베이스만으로 위험도를 평가할 경우 미래 사고 발생을 예측하는데 한계가 있을 수 있으므로 데이터베이스의 보강 및 보정이 필요하다.
