To minimize secondary damages from marine environment pollution resulting from marine accidents, International Maritime Organization(IMO) adopted "Guidelines on Places of Refuge(POR) for ships in need of assistance" as Resolution A.949(23) in it is 23rd General Assembly in 2003 and recommends Parties to the Organization designate PoR. This resolution suggests that they establish a "Decision-Making process" so as to provide reasonable PoR when disabled ships request use of PoR. Korea has not been performed introduce a PoR system in the country. Therefore, there is no decision-making process to deal with ships which need PoR. When Korea implements the PoR system in the future, the nation should establish a Decision-Making process to provide reasonable PoR in case ships in need of assistance request for PoR. In order to present what should be considered in the process of establishing a Decision-Making process for PoR in Korea in the future, in this study presents matters which should be considered in the process of founding PoR Decision-Making processes. When Korea tries to conduct POR system so that other countries' PoR Decision-Making process and the relating process of IMO and REMPEC (Regional Marine Pollution Emergency Response Centre for the Mediterranean Sea) were investigated and analyzed. In addition, in times of marine accident in Korea's sea areas, Korea's action manuals for marine accident which regulates management for an accident is analyzed and articles will be presented to be taken into account during establishing final PoR Decision-Making process.

The AIS(Automatic Identification System) transmits the position of ships and other information to prevent accidents which could occur in the sea. It has to be developed SOTDMA(Self-Organized Time Division Multiple Access) Algorithm which is important on wireless communication method for the AIS because It is based on ITU(International Telecommunication Union) M.1371-1 of the international standard therefore, we need to develop a performance evaluation simulator efficiently to develop and analyze SOTDMA Algorithm. this paper shows the method of designing it. Real ships access The VHF maritime mobile band but in this performance evaluation simulator several ship objects access the shared memory. Real ships are designed as the object and the wireless communication channel is designed as the shared memory. The ships apply for real virtual data which got from assistance hardware and The SOTDMA Algorithm driving state verifies the performance evaluation simulator by IEC(International Electrotechnical commission) 61993-2. After verifying results the performance evaluation simulator is correctly satisfied with IEC 61993-2. So we expect that it helps not only the AIS technology developed but also verify new SOTDMA Algorithm

On December of 2003, IMO's $23^{rd}$ Assembly discussed 'Guidelines on places of refuge for ships in need of assistance' At the discussion, Res. A.949(23) has been selected to appoint recommended place of refuge for countries signatory to the IMO Convention. IMO defines "Places of Refuge" as a places where a ship in need of assistance can take action to enable it to stabilize its condition and reduce the hazards to navigation, and to protect human life and the environment. Appointing and managing a Place of refuge can be a delicate problem because of its close connection to each country's coastal and environmental protection policies. However, in case of marine accident, the appointment or management of the place of refuge has a potential to avoid further damage and reduce to the minimum any environmental and estate losses. Currently a number of foreign countries, designated and operated a place of refuge. But, place of refuge selected method criteria were different by country and also does not have any standardized designating place of refuge model. Therefor, this study suggested the model of assigned places of refuge according to objective indication in order to assign reasonable and efficient places of refuge in domestic waters in the future by investigating and analyzing imported facts in considering the assignment of places of refuge in foreign countries and describing these imported data into quantitative value. In designating the model place of refuge, the final place of refuge location was presented by evaluating the probability of marine accidents, analyzing the location, and evaluating the supporting establishment.
