In this paper, The monitoring system for TV advertisement is implemented using video watermark. The functions of the advertisement monitoring system are monitoring the time, length, and index of the on-air advertisement, saving the log data, and reporting the monitoring result. The performance of the video watermark used in this paper is tested for TV advertisement monitoring. This test includes LAB test and field test. LAB test is done in laboratory environment and field test in actually broadcasting environment. LAB test includes PSNR, distortion measure in image, and the watermark detection rate in the various attack environment such as AD/DA(analog to digital and digital to analog) conversion, noise addition, and MPEG compression. The result of LAB test is good for the TV advertisement monitoring. KOBACO and SBS are participated in the field test. The watermark detection rate is 100% in both the real-time processing and the saved the processing. The average deviation of the watermark detection time is 0.2 second, which is good because the permissible average error is 0.5 second.

Traffic violations such as moving while the traffic lights are red have come from a simple omission to a premeditated act. The traffic control center cannot timely monitor all the cameras installed on the roads to trace and pursue those traffic violators. Modern vehicles are equipped and controlled by several sensors in order to support monitoring and reporting those kind of behaviors which some time end up in severe causalities. However, such applications within the vehicle environment need to provide security guaranties. In this paper, we address the limitation of previous work and present a secure and privacy preserving protocol for traffic violation reporting system in vehicular cloud environment which enables the vehicles to report the traffic violators, thus the roadside clouds collect those information which can be used as evidence to pursue the traffic violators. Particularly, we provide the unlinkability security property within the proposed protocol which also offers lightweight computational overhead compared to previous protocol. We consider the concept of conditional privacy preserving authentication without pairing operations to provide security and privacy for the reporting vehicles.

It has been increased to use the SAN with increasing the size of storage device. In this paper, we design and implement a backup system to support the tape and disk based backup with devices and media in SAN cluster. Our backup system provides device and media management for efficiently managing a number of devices and media in SAN cluster. It also supports script management to process an additional tasks requested by clients and monitoring to control and manage tasks in execution. In addition, it supports reporting to offer backup and restore information to clients.

In an effort to decrease aviation accident worldwide, development of aviation safety management has been sought through aviation index and standardization, both by establishing SMS(Safety Management System). It also needs to be done in the domestic. both study on SMS which ICAO recommends and setting the top priority safety goal, each differently classified by nations. Accordingly, defining safety index and developing continuous monitoring approach. Aircraft accident reporting system in Air Force does not operate in a open approach method due to its uniqueness related to mission achievement. Therefore, limits of utilizing the recent worldwide aircraft data sharing and analyzing results to prevent accident is inevitable. This paper introduces an overview of ECCAIRS 5 which become the standard for the recent worldwide aviation safety reporting and data exchange system. Also using ECCAIRS 5, aircraft accident cases of the Air Force are classified such as accident type, year, month, occurrence category, and flight phase. The result of the study will provide a guide line for utilizing the civil system in prevention of future military aviation accidents.

In present, most of metallic structures (gas pipeline, oil pipeline, water pipeline, etc) are running parallel with subway in Seoul and Pusan.In this case, subway system make a stray current due to electrical corrosion on metallic structures. The owner of metallic structures has a burden of responsibility for the protection of corrosion and the prevention against big accident such as gas explosion or soil pollution and so on. So, they have to measure and analyze the data about P/S(Pipe to Soil) potential, amplitude of stray current, point of source of stray current and so on. In this paper, results of development about Wireless Remote Monitoring and Control System on Underground Pipeline in Stray Current Conditions are presented. And also field test data should be reporting.

Along with response of the Climactic Change Convention, the government is demanding a measuring and reporting system for green-house gas emission and energy consumption on the railroad sector in order to make a transition to a low carbon green railroad system. According to the plans to electric railway line and increase the number of electric rolling stock, the electric consumption is increasing more than the consumption of diesel. Therefore, the development of monitoring device for green-house gases became important issue. In this study we developed a prototype of the monitoring system for estimating electric consumption. This study is expected to make accurate GHG emission inventory and be used to have confidence of emission factor.

It is clearly understood that e-navigation is beneficial to prevent collision and grounding of ships. The purpose of this study is to define and present a future ship operation system under the e-navigation environment in order to provide clear direction for the design of Korean e-navigation system. The future ship operation system consists of shipboard navigational system, shore supporting system and maritime communication system. To achieve the objectives of this study, the ship operation system was discussed separately into SOLAS ships and non-SOLAS ships in this study. In SOLAS ships, mariners become a system manager, choosing system presets, interpreting system output, and monitoring vessel response. In small ships and fishing vessels, mariners may enjoy their navigation by using the automatic tracking of ship's position on the portable electronic chart display. The improved bridge design, integrated and harmonized navigational system and single window reporting will reduce significantly the administrative and physical workload of mariners. Mariners can concentrate their attention more on navigational duty under the e-navigation environment. To build an effective Korean e-navigation system, the essential navigational functions and e-navigation services for small ships and fishing vessels must be identified and developed taking into account user needs.
