Airborne noise is one of the considerable environmental factors for navy ship personnel who should accomplish their tasks in restricted ship spaces against adverse health effect of noise. However, it is difficult to find studies on actual condition of airborne noise for navy ships. In this study, we measured airborne noise levels at 379 compartments of 33 Korean navy ships. Using the measured data, we presented mean values and their standard deviations of measured noise levels with factors of ship type, compartment category, and operation mode. Additionally, we evaluated the mean value and cumulative probability of airborne noise levels of compartments with those of the US navy ships. These results can be rationally used in making the proper airborne noise criteria of the navy ship for the future.

Objective: The aim of this study is developing the navigation radar display of navy ship with ecological interface design (EID) framework. Background: Navy ship radar operator must perform navigation support tasks by monitoring the complex and diverse information presented on the radar display. Current radar display is limited in effective navigation aid and response to an unusual state immediately. It is necessary to develop an effective radar display. Method: Ten navy radar operators performed a series of trials in a low-fidelity radar simulation in which they attempted to solve the problems of current navigation situation. Results: The result demonstrated that the ecological interface's performance was better than the existing radar display on performance time and subjective mental workload. Conclusion: This study expand EID study field to navy ship radar display and confirm ecological display is better than existing radar display in performance time, subjective mental work load. Application: The result of this study may help to improve navy ship navigation radar display currently in use.

The purpose of this study is finding the key factors for navy to determine the necessity of naval ship PIP(Performance Improvement Program) against the altered battle field environment and politics. Recently, leading countries try to cope actively with the changing international circumstances and technology development trend in the commercial industry. In the case of domestic situation, based on the regulation, it is possible to modify the ship configurations by PIP, but there are not enough criteria and references to make a decision of necessity for the PIP program considering the naval ship acquisition planning by navy. It is necessary to acquire the obvious decision criteria for determination of PIP commencement, by the operational, political and security environment around the Korean peninsula. Considering these conditions, this study proposes the factors necessary for naval ship PIP for navy.

In a series of recent launch tests, North Korea has been improving the firepower of its missiles that can target South Korea. North Korea's missiles and submarines are capable of threatening targets in South Korea and are likely faster and more covert than the systems previously seen in North Korea. The advanced threats require that ROK Navy should not only detect them earlier than ever but also response quicker than ever. In addition to increasing threats, the number of young man that can be enlisted for military service has been dramatically decreasing. To deal with these difficulty, ROK navy has been making various efforts to acquire a SMART warship having enhanced defense capability with fewer human resources. For quick response time with fewer operators, ROK Navy should improve the efficiency of systems and control tower mounted on the ship by promoting the Ship System Integration. Total Ship Computing Environment (TSCE) is a method of providing single computing environment for all ship systems. Though several years have passed since the first proposal of TSCE, limited information has been provided and domestic research on the TSCE is still in its infancy. In this paper, we apply TSCE with open architecture (OA) to solve the problems that ROK Navy is facing in order to meet the requirements for the SMART ship. We first review the level of Ship System Integration of both domestic and foreign ships. Then, based on analyses of integration demands for SMART warship, we apply real time OA to design architecture for TSCE from functional view and physical view. Simulation result shows that the proposed architecture has faster response time than the response time of the existing architecture and satisfies its design requirements.

This paper describes a comprehensive analysis of the air defense capability of Aegis class ships on the netted battlefield. A principal threat to ships at sea is anti-ship cruise missiles. The missiles flies lower, faster, and with less radar cross section than its predecessors. Therefore, the ship of the 21s1 century must have the future operational capability based NCW to engage this threat and then the survivability of ship can be guaranteed. This operational concept is reflected in Aegis ship and CEC of US navy, In the near future, the korean navy will be possessed a few Aegis class ships. In this view, this paper has analyzed the intercept range of the sea-skimming ASCM to measure the area defense capability of the Aegis ship in PCW and NCW, respectively and presented the air defense capability of the ship on the netted battlefield.
