P-3C/K aircraft for maritime patrols that Republic of Korea Navy is using, is equipped with a variety of sensors and communication devices. Collected data from the aircraft is managed as tactical information by flight operators and stored. When the flight mission is completed, this information is transferred to tactical support center on the ground and played back or used for follow-up work through a analysis tool. During a flight mission, there are tens of thousands of detection objects within an hour in KADIZ (Korea air defense identification zone). In contrast, in TSD (tactical situation display), which displays a map when using the analysis tool, all detected objects are expressed as symbols. The increase in display symbols has a significant impact on the TSD image updating and consequently interferes with the smooth operation of operators. In this paper, we propose applying multiple threads and multiple layers to improve the performance of existing TSD. And the performance improvement is proven through the execution results.

Air threat such as aircrafts or missiles were incresed rapidly after World War II, warships were relatively vulnerable to air threat. Therefore U.S. and allies developed various Tactical Data Link(TDL) to defend warships from air threat. Target information can be managed and shared with other station by real or near-real time due to TDL. TDL is base system to manage battlefield and to carry out C2(Command and Control) effectively and rapidly. In this paper, the type, current operating status and characteristic of TDL is surveyed and newest technical trend such as LINK-K is described.

The purpose of this study is to investigate how the customer's attitudes and behavioral responses, depending on the persuasion tactics of salespeople in customer service and meeting point. The tactics of persuasion of customer acceptance and purchase depending on the type of salesperson with proven effectiveness of even comes out to investigate what results according to the purchase form and the customer that the customer consumes gender. Results First, the tactics of persuasion tactics of coercive tactics to mention the loss of a salesman showed that increasing the degree of acceptance than non-coercive tactics to help consumers buy the information provided above. Second, coercive tactics to adjust the effect with respect to the degree of acceptance of the purchase of helping consumers to purchase in the online form has been proven to be more effective than non-coercive tactics case. Third, adjusted for gender effects were proven to help women with respect to the degree of acceptance of a consumer purchases more effective than men. That is, in consumer contacts, the persuasion tactics of salespeople depending on the customer's acceptance and purchasing intention showed that coercive tactics has the more positive impact on online forms and women.

The tactical operation centers of future anti-aircraft missile systems provide the environment for the research on future air threats, tactical information, integrated battlefield environment creation and management, engagement control and command and control algorithms. To develop the key functional elements of integrated battlefield situation creation and processing and tactical operation automation processing operations, battery/battalion tactical operation control and reconfiguration design software are required. Therefore, the algorithm software of each function and the tactical operation display software and link software for interworking between equipment were developed as reconfigurable through a data-centric design. In this paper, a tactical operation display framework that can be reconfigured on the operation display of the tactical operations according to the battery/battalion is introduced. This tactical operation display framework was used to develop a common data model design for the reconfigurable structure of multi-role tactical operations with battery / battalion and mission views, and a display configuration tool that provides a tactical operation display framework for view development was also developed using the MVC pattern. If the tactical operation display framework is used, it will be possible to reuse the view design through the common base structure, and a view that can be reconfigured easily and quickly will also be developed.

The Navy is trying to develop a sonar-operation strategy that efficiently searches for underwater targets. To develop an efficient sonar-operation strategy, a simulation system, which can analyze the efficiency of various operation strategies, is needed. The simulation executes the strategical operation by collecting information of sea environment, destroyer, sonar, and target. Also, it should be able to provide diverse information according to its progression. In this study, the simulation system that can evaluate and analyze the effectiveness of the search strategy for underwater targets in different environments was designed and developed. The simulation system was developed, utilizing the sonar equation and the lateral-range-curve, and it portrays many patterns of realistic movements of a target. This system will contribute to developing and improving efficient sonar-operation strategies to find underwater targets in the future.

A naval tactical video has utilized to implement network based remote C2 system, but it is difficult to transmit video intelligence data between tactical combat team and base-station due to the distance and sea condition. Threrfore, We first understand the naval tactical video transmission system and identify its limitations. Finally, we present an efficient method to increase transmission rate in the naval tactical video transmission system.
