In this age, where the social environment is changing rapidly and unpredictably, interest in safety from crime is increasing in Korean society. As the desire to live a life free from the fear of crime increases, interest in the construction of safe cities is also rising nationwide. To meet the national demand, the Korean government is promoting a project to link public disaster safety systems by involving municipalities, 112, 119, and other emergency services and institutions through the Smart City Integrated Platform in order to construct a smart safety net. This study investigates the linking of theSmart City Integrated Platform and theIntelligent Security Project. The results are as follows. 1. The linkage's objective is clear. 2. The system sector can provide information to accident-related organizations. 3. The scenario area can be expanded to a crime-prevention sector, and a long-term urban information integration infrastructure can be created. 4.

It is needless to say that the port security is very important owing to the geographic setting of Korea and the possibility of the provocation by North Korea. In addition, The security management is necessary for the port and the domain of maritime to block the inflow from overseas because of the increase of international crime as terrorism. The training system for port security guard should be constructed to secure the specialization of the manpower for the efficient port security management. But the training system of port security manpower is not unified and the training is not carried out, therefore it is necessary to improve the training system of port security manpower. In this study, the improvement plan of training system is suggested as follows. First, the unification of the legislation of port security should achieved to establish the guidance of training for port security guard. Second, the specialized training per activities should be done. And lastly, the qualification system should be introduced for the specialization of port security manpower.

This study has aware of the seriousness of public official. and come up with an effective counterplan about public official. This research is a study on previous research on government and officer crime. And understanding is the status about public official. It proposed ways to solve the problem Drunk driving is illegal to drive a vehicle while drunk act. Drunk driving is likely the potential to cause a traffic accident. As a result, drinking and driving is decreasing since the mid-2000s. The cause of the change is to strengthen social awareness, regulations for drunk driving. and public official was decreased. However, it did not disappear. Cause of drunk driving is wrong, such as dinners and cultural distrust of the deputy driving, drinking after misjudgment on his physical condition. public official is a bigger influence. It is a social problem. Personally great damage to organization. Therefore, this study is an analysis of international practices and domestic best practices. Officials drunk driving drunk driving prevention measures are proposed to strengthen preventive measure, it is proposed the organization of internal control measures, union officials supporting the improvement of company dinner.

Recently, Population has been concentrated in cities due to rapid economic growth. As a result, urban buildings are becoming more dense, high-rise, and diversified. The shape of these urban buildings increases the risk of fire, accidents and crime. The narrow living space has the characteristic of the unchanged floor. In case of a fire, the living space of the narrow residence is large in the damage because the smoke diffusion rate is fast. The radio wave transmittance and transmission distance of wireless communication used in fire fighting operations vary depending on the type of building materials and buildings. Therefore, this paper analyzes the building materials and structural characteristics of the narrow residential space for efficient fire fighting operations. We have developed a communication environment solution for a narrow residential space for the optimal fire fighting operation through the measurement of the radio wave transmittance and the transmission distance of the wireless communication.

The Car License Plate Recognition(: CLPR) is required in searching the hit-and-run car, measuring the traffic density, investigating the traffic accidents as well as in pursuing vehicle crimes according to the increasing in number of vehicles. The captured images on the real environment of the CLPR is contaminated not only by snow and rain, illumination changes, but also by the geometrical distortion due to the pose changes between camera and car at the moment of image capturing. We propose homographic transformation and intensity histogram of vertical image projection so as to transform the distorted input to the original image and cluster the character and number, respectively. Especially, in this paper, the Multilayer Perceptron Algorithm(: MLP) in the CLPR is used to not only recognize the charcters and car license plate, but also determine the optimized ratio among the number of input, hidden and output layers by the real experimental result.

Low birth rates and aging problems are raising a big issue in the worldwide. Recently, Korea also has no one to caring children who have low discernment and old ones who have Alzheimer's disease because of growing nuclear families and dual income furnitures. Therefore many serious crimes like kidnappings were occurred by people who have mental problems or bad intentions. Even though missing and ding alone are increasing together. The result of it, the needs of potable GPS system, to tracking for the olds and week ones, is highly growing nowadays. This paper introduce producing prototype tracker, looks like fashion accessories, which is using GPS, Zigbee and WiFi. It expects developing many accessory types of trackers effectively helps protect children and old ones from kidnappers at a low cost in this aging society.

Children's use of the Internet is growing. Each company collects children's personal information. However, it is also difficult for children to recognize the concept of personal information. In this study, based on the analysis of newspaper children's personal information leakage, we investigated the occurrence of personal information leakage in children through ground theory, one of qualitative research methods used in the social science field. The ground theory is thought to be able to derive a causal relationship by identifying the leakage of children's personal information. As a result of the study, it was collected through the consent of the legal representative, but depending on the situation, the consent process was not performed. Even with the consent, it was found that due to insufficient measure to protect personal information, various situation(criminal damage, anxiety, embarrassment, anger, etc.) occurred the legal representative. As a result, children's personal information collection providers paid fines according to the situation.

Space Syntax methodology can be quantitatively calculated spatial cognitive analysis by number of turns_ In the existing GIS-based spatial information service provide 'physical distance' due to the shortest distance as a priority. but pedestrians tends to choose the path with concerned a lot of emphasis of safety, more vitality way from the crime at night, traffic accidents, and comfort on a road. Human's 'psychological distance' may reflect the spatial information services and provided path should be. In this study, using GIS Road Data implements the axial map with idea of the linear simplification principles. Traditional axial map of the Space Syntax get the assumption from the actual traffic values by comparing the results of correlation relationship. Through these methods, the actual relationship between traffic and test values have the correlation value($R^2$= 0.5387) 50% level and was able to get the results.

As IT industry using networks have been developed explosively, online operations that were conducted in offline are increasing rapidly, and even relationship with other people made online. As online crimes are increasing accordingly, building security networks is getting very important. As a result, network separation between business and organization network has been performed recently, but this causes network user inconvenience and efficiency reduction. In this paper, we propose reassociation methods for already separated networks for many public organizations. We implement two reassociation methods using NAT device and shared storage and show their experimental results.
