A primary task of fire department is maintaining public safety, system maintenance and welfare improvement by protecting life, body and property of a people through prevent and extinguish of the fire in emergency. Rescue part of those affairs has supported by the people but affairs related to the fire examination and investigation could not get it. Although fire examination is a very important part of fire department administration, it has been understood indifferently due to lack of awareness and concern. There are no scientific fire examination because of lacking education study and the whole responsibility capacity about it. There are many things have to be improved at fire examination and investigation system in Korea. Especially, establishment of the whole responsibility post is urgent through assuring professionals to improve accuracy of fire examination and investigation. Equipment which can do scientific fire examination and investigation have to be fully furnished. Efficiency of fire examination and investigation has to be increased through improving law related to fire examination and investigation, giving rescuers investigation right. Through this, it systematically have to be good for fire prevent.

Distribution, duplication and manipulation of the digital contents are very easy due to the characteristics of the digital contents. Thus, damages of invasion of property right rapidly increase due to infringement of copyright for the digital contents. To prevent illegal use and to settle conflict about ownership of the digital contents, continuous efforts with enormous expense are devoted. In this paper, we design and implement real-time audio watermarking system to protect ownership and copyright for the digital contents. The proposed system also clarifies where the responsibility about the illegal distribution lies. The system has convenient user interface so that general administrator without an expert knowledge of the protection of copyright can use easily. In addition, unlike the traditional watermarking system, our system has merit to offer information about the illegal distribution for clear post-management.

Right comprehension of the natural disaster could reduce the damage of human life and property by explaining the cause of the disaster and considering a counterplan to decrease or prevent it. To do this, it should precede to clarify the category of the natural disaster and classification. Also, when the disaster occurs, swift site survey and the establishment of the data by the professionals should be done for clarifying the reason. Our classification of the natural disaster is written on the Law of the Nature Disaster Relief. But, this classification is made for the management of the disaster, so it is required to review the establishment of the technical information by the professionals. Therefore, the Korean type classification is required considered by the professionals who collect and study the information of the natural disaster for the other countries. If the DB of the natural disaster is made, it is able to get various services through the internet virtual space and it will be helpful to prepare the prevent countermeasures against the disaster. In this research, the korean type classification plan of the natural disaster is suggested which is suitable to the professional technology by collecting and analyzing the domestic and the international classification of the natural disaster.

Recently, aerial laser scanning technology has received full attention in constructing DEM(Digital Elevation Model). It is well known that the quality of DEM is mostly influenced by the accuracy of DTD(Digital Terrain Data) extracted from LiDAR(Light Detection And Ranging) raw data. However, there are always misclassified data in the DTD generated by automatic filtering process due to the limitation of automatic filtering algorithm and intrinsic property of LiDAR raw data. In order to eliminate the misclassified data, a manual filtering process is performed right after automatic filtering process. In this study, an algorithm that detects automatically possible misclassified data included in the DTD from automatic filtering process is proposed, which will reduce the load of manual filtering process. The algorithm runs on 2D grid data structure and makes use of several parameters such as 'Slope Angle', 'Slope DeltaH' and 'NNMaxDH(Nearest Neighbor Max Delta Height)'. The experimental results show that the proposed algorithm quite well detected the misclassified data regardless of the terrain type and LiDAR point density.

This research differentiate the technique of Jungkwon-jirugi, one of the basic movements of Taekwondo, into two movements stop-jirugi and push-jirugi and gives analysis of the impulse, acceleration and velocity in the point of motor control. For this, we tried graphic analysis using an acceleration sensor and high speed camera which was made from USA in 2005 and took pictures at 250 frames per second. We reached the following conclusions. First, the acceleration wave of push-jirugi was a period longer than stop-jirugi, meaning that the push-jirugi motion asserts force for a longer time. Second, the acceleration and velocity graph shows that the highest velocity occurs on the point when the acceleration begins to decrease right after reaching its maximum. Third, according to the image analysis using the high speed camera, we could find out that the shoulder is pushed a little even in the stop-jirugi motion.

The rapid development of digital media and communication network urgently brings about the need of data certification technology to protect IPR (Intellectual property right). This paper proposed a new watermarking method for embedding owner's audio signal. Because this method uses an audio signal as a watermark to be embedded, it is very useful to claim the ownership aurally. And it has the advantage of restoring audio signal modified and especially removed by image removing attacks by applying our LBX(Linear Bit-expansion) interleaving. Three basic stages of our watermarking include: 1) Encode . analogue owner's audio signal by PCM and create new digital audio watermark, 2) Interleave an audio watermark by our LBX; and 3) Embed the interleaved audio watermark in the low frequency band on DTn (Discrete Haar Wavelet Transform) of image. The experimental results prove that this method is resistant to lossy JPEG compression as standard image compression and especially to cropping and rotation which remove a part of Image.

Since the 1950s, crime prevention was to figure out how dissident. Unlike traditional crime prevention was a point of view. Physical environment and a method to prevent crime, "Crime Prevention Through Environmental Design (Crime Prevention Through Environmental Design: CPTED)" is the prevention of crime, property crime, criminals and human right with the surrounding environment. These CPTED has a variety of factors. Natural surveillance of these is the most basic elements. Natural surveillance is monitored by monitoring the behavior of criminals, to prevent crime. CPTED was the large majority of existing studies focused on a study area. However, this study examined the area around a house. Made to secure the hypothesis of natural surveillance to affect fear of crime. Research on fear of crime and crime victimization declined. Thus, the securing of natural surveillance proved to be effective in crime prevention in this study.

This paper presents a lane-departure identification (LDI) algorithm for a traveling vehicle on a structured road. The algorithm makes up for the weak points of the former method based on EDF[1] by introducing a Lane Boundary Pixel Extractor (LBPE), the well known Hough transform, and liner regression. As a filter to extract pixels expected to be on lane boundaries, the LBPE plays an important role in enhancing the robustness of LDI. Utilizing the pixels from the LBPE the Hough transform provides the lane-related parameters composed of orientation and distance, which are used in the LDI. The proposed LDI is based on the fact the lane-related parameters of left and right lane boundaries are symmetrical as for as the optical axis of a camera mounted on a vehicle is coincident with the center of lane; as the axis deviates from the center of lane, the symmetrical property is correspondingly lessened. In addition, the LDI exploits a linear regression of the lane-related parameters of a series of successive images. It plays the key role of determining the trend of a vehicle's traveling direction and minimizing the noise effect. Except for the two lane-related parameters, the proposed algorithm does not use other information such as lane width, a curvature, time to lane crossing, and of feet between the center of a lane and the optical axis of a camera. The system performed successfully under various degrees of illumination and on various road types.
