In an IP network, various types of traffics are statistically multiplexed to utilize efficiently the network resources. The DiffServ-aware-MPLS supports a wide variety of communication services with different QoS requirements. The DiffServ-aware-MPLS based on QoS architecture had become one of the most promising ways to guarantee QoS Multi-service IP network. But how to manage IP network with QoS guarantee is still an open issue. In this paper, we propose DiffServ-aware-MPLS buffer management technique using the specified policing, queuing, and scheduling

DiffServ 망에서 완전한 QoS를 망 사용자에게 제공하기 위해서는 downstream 트래픽 뿐만 아니라, upstream 트래픽에 marking, policing 을 적용해 주어야 한다. 본 논문에서는 downstream 트래픽에만 QoS를 적용하는 단방향 트래픽 제어기법과, downstream및 upstream 트래픽에 QoS를 적용하는 양방향 QoS 서비스 기법을 비교하기 위하여, cisco 라우터를 이용하여 QoS 테스트베드를 구성하고, 성능을 측정 및 분석하였다.

Motorcycle patrol is used for traffic control and enforcement in highly congested areas. One of the major problems with this form of patrol is that it is extremely dangerous since just about any type of accident tends to cause harm to the rider. The purpose of this study is to analyze the effectiveness of police motorcycle patrol, and to suggest the methods for improving the effectiveness of police motorcycle patrol. This study conducts the survey on 139 policemen that belong to Daejeon Provincial Police Agency that had implemented motorcycle patrol. By factor analysis, the intimacy between policemen and citizens, the excellence of patrol devices, the speed of response, and the appropriacy of patrol method are grouped as the independent variables. And the dependent variable is the effectiveness of police motorcycle patrol. The results of this study demonstrates that the effectiveness of police motorcycle patrol is affected statistically by the speed of response, the appropriacy of patrol, and the intimacy between policemen and citizens. But, the intimacy between policemen and citizens affected the effectiveness negatively. Therefore, police department must make the effort for increasing the speed of response and enhancing the appropriacy of patrol. Also, police department must make patrolmen sincerely conscious of the value of police-community relation.

This study is aimed to analyze problems of police budgetary execution and to suggest better ways for establishing effective budget implementation as well as legitimacy of securing budget in the field of police work. For this purpose, this paper analyzed the annual reports on police budgetary execution, from 2009 to 2012, conducted by National Assembly Budget Office. In result, most parts of the police budgetary execution were not satisfied with the audit standard, and especially in terms of management of budgetary execution, it showed 40% in inappropriateness. In addition, excessive and underestimate appropriation in the police budgetary execution, which happened frequently in other offices, was recorded on the second place. 10% of the amount of budget was executed for ordinance violence. Given results analyzed from each division, Transportation Division occupied 40% of the amount of related problems and all of types in the field did not meet the audit standard, thus it is required to manage budgetary execution effectively. In terms of Public Safety Division, the problem was related to budgetary allocation prior to execution, such as overlap in other works, excessive and underestimate appropriation, and inappropriate business plans. Director General for Planning and Coordination did not meet the standard of law system maintenance, Given the light of the result of analyzing programs, traffic safety and securing communication was the most problematic and support for police administration, crime prevention and protecting the disadvantaged, educating professional police officers, and establishment of policing infrastructure were required to be reformed in sequence. In order to resolve these problems, it is demanded to check budgetary execution and the process in business plans on a regular basis. Additionally, in case of using budget in inappropriate parts, tough penality including reduction of budget in related to the local police should be implemented to increase the importance of budgetary execution. Moreover, because of the fact that a part of problem of budgetary execution was originally caused by the budgetary allocation, it is advised to allocate police budget using the budget proposal of National Finance Act and Ministry of Strategy and Finance.
