This paper deals with development of an oil boom computation program (OBC Program) for effective response to oil spill. Currently, programs for showing required minimum quantities of oil skimmers and temporary storage tanks have been developed. However, a program for oil boom has not developed, which causes difficulties in oil spill management. The OBC program was developed using LabVIEW 2010 for solving above problems. The OBC program has following strengths: 1. Both experts and non-experts can calculate required quantities of oil booms, 2. The program can save response time, 3. It can reduce damage to properties and marine environment in proportion to reduced response time.

China's new Maritime Policy Law (MPL) purports to regulate the duties of China's maritime police agencies, including the China Coast Guard, and safeguard China's sovereignty, security, and rights and interest. The MPL has potentially far-reaching application, as China claims extensive maritime areas off its mainland and in the South China Sea. This expansive application of maritime law enforcement jurisdiction is problematic given that most of China's maritime claims are inconsistent with international law. To the extent that the MPL purports to assert jurisdiction over foreign flagged vessels in disputed areas or on the high seas, it contravenes international law. Numerous provisions of the MPL regarding the use of force are also inconsistent with international rules and standards governing the use of maritime law enforcement jurisdiction, as well as the UN Charter's prohibition on the threat or use of force against the territorial integrity or political independence of any state. China could use the MPL as a subterfuge to advance its illegal territorial and maritime claims in the South and East China Seas and interfere with coastal State resource rights in their respective exclusive economic zone.

The nature of deaths occurred at sea may be revealed the differences from that in the land, but there is no comprehensive statistical analysis of deaths occurred at Korean Sea so far. Therefore, the cases of deaths or missing in the period 1993 - 2006 were analyzed by the cause, place of death, and results of preliminary investigation. In the period from 1993 to 2006, over 1000 peoples were died or missing every year. The cases of marine safety accidents including self-carelessness and mishap were approached over 60% and cases of homicide were less than 1%. The closure cases of preliminary investigation were reached over 70% and the most of deaths occurred in fishing vessels (the range of 20 ~ 99 tonnage). The suspension cases of preliminary investigation were reached to 70% of all missing and drowning cases. The results showed that the most of deaths occurred at sea could be prevented by the safety regulations including mandatory report of accidents, marine safety education and training, punishment the people responsible for the accidents. For the unidentified bodies, data should be collected and recorded for the future identification. The crime scene investigators should be trained to ensure the quality of their professional skills regularly.

In order to develop the standard service model of Korea Coast Guard at fishing port, which responses to the demand of users and provides them with the high quality service of maritime administration, the services performed by a branch of KCG are analyzed and the level of familiarity with them are investigated. The degree of affair achievement is quantitatively standardized by assessing the workload of branch office. The standard model of affairs is formatted and the programs of organization, resource operation and education are proposed.

This paper showcases the study of 150 Coast Guard officers on how work environment compatibility impacts their organization and job attachment. The independent variable, work environment compatibility, is separated into three sub-variables, which are organization compatibility, job compatibility, and supervisor compatibility. The study's results show that job attachment is only influenced by job compatibility while organization attachment is influenced by all three; organization, supervisor, and job compatibility. With these results, we can make suggestions for the development of the Coast Guard organization and further research based on individual characteristics.

The regulation of HNS has been intensified by the international trends including OPRC-HNS Protocol and '96 Convention which was driven by the high amounts of cargo. Due to the characteristics of HNS that would possibly bring potential damage with personnel and assets, effective management and prompt actions are required definitely. In order to respond effectively against HNS accidents, Korea Coast Guard (KCG) is in the process q development of HNS accident response manual and information system which allows On-Scene Coordinator(OSC) and personnels for rescue including an information for hazardous materials, sensitive area to be affected, solution methods and more. Furthermore, KCG is also building up establishment of national and local contingency plans for HNS in accordance with OPRC-HNS Protocol. It is also advised to proceed for the government to solve the anticipated obstacles that include protection equipments to get close to the site, experts allowing to manage accidents and organizations specialized for overall HNS related matters. The proposed issues described above are planned to conducted on basis of government.

This paper describes the rheological behavior study such as viscosity and change of shear stress regarding marine lubricating oil according to the amount of Marine Gas Oil (MGO) dilution. The viscosity reduction due to fuel dilution is crucially important characteristic to decreasing engine durability because of the abrasion of piston ring or liner. The lubricating oil used in this paper was blended with magnetic stirrer diluted High Sulfur Diesel (HSD, 0.05 wt%) ratio of 3 %, 6 %, 10 %, 15 % and 20 %. The viscosity and shear stress of diluted lubricating oil were measured with the temperature range from $-10^{\circ}C$ to $80^{\circ}C$ using a rotary viscometer (Brookfield Viscometer). As the amount of MGO dilution increasing in lubricating oil, the viscosity and stress of those decreased, because the lubricating oil diluted MGO with low viscosity show the trends to decreased viscosity and shear stress. Especially, the viscosity and shear stress of lubricating oil radically decreased at low temperature ($0{\sim}-10^{\circ}C$) and doesn't effect in MGO dilution at over $40^{\circ}C$. As temperature risen, the reduction of the viscosity and shear stress in lubricating oil shows the Newtonian behavior. The lubricating oil was required to check up periodically to improve engine durability since the viscosity reduction by MGO dilution accelerating the engine abrasion.

Operational errors caused by human factors, which is the major cause of marine accidents, include lack of knowledge, misunderstanding knowledge, and inadequate procedures. Recently, the type of propulsion mounted on KCG cutters has been diversified. In particular, the water jet propulsion unit, which was mainly installed in small boats, have been gradually expanded to medium and large size Coast Guard cutters, reaching 50% of the total. Axes types are divided into 2 to 4, and the bucket types are divided into Double Reverse Bucket(DRB) and Single Reverse Bucket(SRB); in these, the backward and steering control methods are completely different. Diversification of these operating systems can increase factors causing human error by the ships' operators. However, there is a lack of research on the maneuvering methods, considering the inherent active characteristics of each type of water jet. In this paper, we analyze the sideway method suitable for the condition of Coast Guard Exclusive wharf without assistance, based on the astern performance of each type. Then, a ship handling simulator was used for the experiment; they compared and verified through interviews of captains.
