Predicting the survival time of a person in water (PIW) in maritime search and rescue (SAR) operations is an important concern. Although there have been many studies on survival models in marine-developed countries, it is difficult to apply them to Koreans in Korea's oceans because they were developed using marine distress data from the United Kingdom, United States, and Canada. Data on the survival time of a P IW were collected through interviews and surveys with a special rescue team from the Korea Coast Guard, SAR cases, press releases, and Korea Meteorological Administration data to address these issues. The maximum survival time (Korean) equation was developed by performing a regression analysis of this data, and the applicability to actual marine distress was reviewed and compared to the overseas survival model. By comprehensively using the maximum survival time (Korean), domestic SAR cases, and overseas survival models, guidelines for survival time and intensive and recommended search time were suggested. The study findings can contribute to decision-making, such as the input for search and rescue units. The findings can also help to determine the end of or reductions in SAR operations and explain policy decisions to the public and families of a PIW.

The 21st century is often referred to as maritime age. The sea is a rich repository of natural resources, comfort shelters and the hopes and dreams of human being. But there is always possibility of disaster as well as hopes and dreams. Although there have been many advances in the ship building technology, the risk of accidents is on the increase due to the increase of maritime traffic and the revitalization of marine leisure. I like to refer to the systematic search and rescue system for the rapid response by analyzing recent marine accidents. For the safe navigation, it is necessary to establish institutional systems such as ship technology, navigation equipments, excellent human resources, traffic control, etc. and navigation components also have to be well organized each other. It is also necessary to build a prompt accident management system. The search and rescue system for the rapid response and the way of reducing the incidence of marine accidents were reviewed through the analysis of recent marine accidents.

As the numbers cf vessels in and out cf korean ports and passing ships through korean waters are increasing, possibilities of marine accidents grow higher and damages caused by such accidents would be expected larger. The author accordingly try to seek for the appropriate measures to enhance the present korean Search and Rescue(SAR) systems and future plans comparing korean system with international movement and relevant systems of maritime advanced countries.

The Korea Maritime Police Agency(KMPA) is the national maritime Search and Rescuee (SAR) authority with the responsibility to promote an efficient organization of SAR services and to coordinate the conduct of SAR operations within the Korean Search and Rescue Region(SRR). The maritime SAR operations shall provide an adequate and effective search and rescue services to minimize the loss by rendering aid to persons in distress and property in the marine environment. The essence of a successful search and rescue operation is the speed with which it is planned and carried out because survivors who need assistance and whose chances of survival diminish rapidly with time. This paper aims to propose an optimal allocation model of maritime SAR fleet in view of minimizing the search and rescue time. When maritime accidents occur, rescue units have to reach to the distress scene within the specified time. For this, SAR units must be redeployed to an advanced base so that Rescue Units(RU) can reach to the scene of distress in the shortest possible time. The Korean maritime SRR is divided into 180 sub-areas in consideration of an operational and technical ability of SAR units. The suggested model is verified through an empirical application to the Korean maritime SRR. And also the Rescue Vessels(RV) required is estimated for each Rescue Co-ordination Center(RCC).

This paper describes two kinds of personal hand-held electronic devices to enhance marine leisure safety. The one is Radar response-type safety device triggering by the pulse signal from a commercial 9GHz-band Radar to provide quick search and rescue with combined civilian-government-military fleets. The other one is M-RFID (Marine Radio Frequency IDentification) based safety electronic device using 900MHz Tx/Rx with spread spectrum frequency hopping and GPS. Through the field tests at sea using Korea Coast Guard's warship the operating performances are verified. Further plan for practical use of each device was also discussed.

During maritime distress, Korean Coast Guard investigates the current status of the distress, such as identifying search objects, to establish a search plan. The ship master is required to submit a report to the competent authority before departure, along with an identity list of the crew and passengers. As a list of the passengers on board is made manually, the waiting time becomes longer, and it is difficult to immediately identify these during maritime distress. The Ministry of Oceans and Fisheries has developed an app to make it easier to register for boarding, but it has been inactive for various reasons. Therefore, this study proposed a plan to improve it. By activating the mobile-phone boarding report system, it is possible to quickly secure the initial location and time of the person in water and provide mental relief to them by acknowledging the receipt of a distress report. In addition, using this information, it is possible to quickly rescue the affected person through public-private partnership.

In wireless sensor networks, we propose an optimization algorithm in order to minimize the consumed energy of nodes for maritime search and rescue. In the marine environment, search and rescue operations are mainly performed on the surveillance side and passively on the rescued side. A self-configurable wireless sensor network can build a system that can send rescue signals in the operations. A simulated annealing algorithm is proposed to minimize the consumed energy of nodes in the networks with many nodes. As the density of nodes becomes higher, the algorithmic computation will increase highly. To search the good result in a proper execution time, the proposed algorithm proposes a new neighborhood generating operation and improves the efficiency of the algorithm. The proposed algorithm was evaluated in terms of the consumed energy of the nodes and algorithm execution time, and the proposed algorithm performed better than other optimization algorithms in the performance results.

In this study the drift prediction models currently used in search and rescue(SAR) operations are introduced and the basic differences among them are analyzed by comparing the target classification, the treatment of environmental conditions, leeway equations and the determination of search area. In addition the new methods under development including AP98 of U.S. Coast Guard are compared and studied to improve the efficiency of SAR operation.
