In this paper, we propose an efficient policing mechanism for Markov model-based traffic descriptors of VBR MPEG video traffic. A VBR video sequence is described by a set of traffic descriptors using a scene-basedMarkov model to the network for the effective resource allocation and accurate QoS prediction. The networkmonitors the input traffic from the source using a proposed new policing method. for policing the steady statetransition probability of scene states, we define two representative monitoring parameters (mean holding andrecurrence time) for each state. For frame level cell rate policing of each scene state, accumulated average cellrates for the frame types are compared with the model parameters. We propose an exponential bounding functionto accommodate dynanic behaviors during the transient period. Our simulation results show that the proposedpolicing mechanism for Markovian traffic descriptors monitors the sophisticated traffic such as MPEG videoeffectively and well protects network resources from the nalicious or misbehaved traffic.

The purpose of the present study is to examine the effect of civic cooperation with the police on the number of crime that the police must solve by conducting simulation based on system dynamics. The study sets police oriented-policing model and police-citizen cooperative model to investigate the effect of civic cooperation with the police. As a result of the simulation, the police oriented-policing model shows that the number of crime that police must solve is increasing over time, while the police-citizen cooperative model shows that the number of crime that must be solved by the police is keeping it stable in the increase of crimes. Comparing both models, civic cooperation with the police is more effective in reducing or deterring crime than police oriented-policing activity. The study proves that building cooperative relationship between citizens and the police can become a strategic method for controlling crime effectively without a rapid increase in police finance. It is meaningful in terms of presenting a dynamic change of interaction for reducing crimes between civic cooperation with the police and policing activity of the police over time.

In modern society, citizen's expectation about policing levels have been rising over time and it limited resources of the police to deal with the security services are insufficient. Until now, the state monopoly of the police activity was changing to subject of a variety in cooperation with public security system. The citizens considers community not the destination to police enforce the law but space for effective policing partners. Japanese police focus on cooperation oriented policing to strengthen the police and local residents with crime prevention for a long time. Also, the community through a variety of problem-solving policing activities to identify problems such as anxiety and anguish of the people. The legal basis for cooperative policing activity is that Nagaoka city crime prevention regulation in 1979. In recent years, Tokyo local government legislated the safe town development regulations(東京都安全 安心まちづくり條例) and set up the hot-spot area to promote the safety of public facilities. Cooperative policing not police intervention for crime prevention but national policy for the city reclamation in Japan. Police as well as the Ministry of Land and Transport, Ministry of Justice, Ministry of Education, Prime Minister and all government departments thread safe city, crime prevention, and has been working to make the safe city. Japan's cooperative policing is a system that receives the most attention and greater implications.

A FR-ATM interworking function that has FR and ATM interfaces, should guarantee the QoS of both frame relay and ATM networks. The IWF requires the policing mechanisms for FR and ATM respectively, and needs to map the traffic parameters each other. In this case, traffic parameter mapping and policing function are performed independently. In the aspect of FR traffic policing, this function degrades processor performance if it is worked by software, or includes additional hardware function. The best way to solve this is to integrate this function into ATM function because ATM is performed by well defined hardware already. In this paper we propose the integrated traffic control mechanism. That is, frames are segmented to cells first, and then policing mechanism is applied to the cells to guarantee the FR QoS. Therefore proper policing algorithm is essential to the integrated FR traffic mechanism. The evaluations are done with simulations in comparison of existing FR algorithms, ATM VBR and GFR policing algorithms, and the proposed algorithm.

Recently, the rapid development of science and technology is a new challenge and opportunity in the policing environment. In the major industrialized countries of the West presents a strategy called SMART Policing the police to strengthen police capacity in accordance with this social change and actively utilize the science and technology in policing field. In this study, we attempted to discuss our country for the establishment of security technology research and development organization. First, I propose that installed the R&D planning department at the Office of Planning and Coordination in the National Police Agency. Secondly, it is need to establish the (provisional) Police Science and Technology Center, that integrate the functions of each organization's R&D-related work. Finally, it should integrate Police Science Institute and the National Forensic Service in (provisional) Policing Technology Research Institute.

These days, the majority of public service area presents increment of utilizing a contracting-out with the following reasons such as cost-efficiency, maintenance of population changes in flexible manner, and convenience of management. The social changes have influence on policing structure and regional security system as well as problems associated with accepting the contracting-out in the public policing sector. However, many issues such as limited contracting-out sector, difficulty of encouragement of participation to private sector, and limitation of making a contract with contracting-out would be brought up when initiate contracting-out to the public policing sector. Changing security system to lower budget, planning restructure of organization, developing alterable partial contracting-out, establishing private and public cooperate system and rationalizing contract system are the suggestions to solve and modify the raising problems. This study suggests a differentiate regulation of policing services compare to currently existing contracting-out method to consider a distinctive working environment. The suggestions are as follows: 1. develop a security segregate model, 2. build a cooperative system between private and public policing sector, 3. broaden opportunity of participation of private policing sector, 4. open-competition among qualified private tender to make a contract. The private contracting-out in the public security service sector should be manage in different manner compare to other private contracting-out in government-oriented public service sector. Since work performance of each private contracting-out agency is strongly bond to safety of every civilian in the nation, it is essential to increase its standard of qualification of each agency.

현대의 경찰활동은 지역사회 경찰활동(Community Policing)으로 귀결된다. 지역사회 경찰활동에 대한 많은 논의가 있어왔지만 지역사회 경찰활동이라는 패러다임에 관한 통합적인 모색은 등한시 되어 온 것이 사실이다. 지역사회 경찰활동에서 파생된 프로그램 및 전략들은 실질적인 경찰활동과 관련이 있다. 이러한 프로그램들은 경찰조직의 이슈 혹은 특정한 문제를 해결하기 위하여 지역사회 경찰활동보다 의도적으로 좁은 범위로 한정하고 있다. 그러한 초점을 가진 대표적인 프로그램은 문제지향적 경찰활동(Problem-oriented policing), 깨진 창(Broken Windows), 컴스탯(Comstat), 제3자 경찰활동(Third party policing), 우범지대(Hot spots)로 볼 수 있다. 그러나 이러한 프로그램 및 전략들은 매우 한정된 범위 내에서 존재하고 운영되는 것들이기 때문에 오늘날의 경찰활동의 근거나 기초를 지역사회 경찰활동만큼 제공해주지 못하고 있다. 지역사회 경찰활동과 관련된 경찰개혁 프로그램이나 전략들을 통합하여 다시 한 번 의미를 재정립하는 것은 현장의 경찰관들이 보다 쉽게 경찰행정의 의미를 이해하고 실제로 실현해 나갈 수 있는 방법을 안내하기 위함이다.

Not only has there been movement along the sectoral continuum, Johnston argues, but changes in the spatial balance of policing are also visible. More concretely, he suggests that British policing has been undergoing a century-long process that has gathered pace since the 1960s. Three factors have been central to this process. First, legislative centralization brought about by the Police Act 1964 - which established the tripartite structure for police governance and amalgamated forces - and the Local Government Act 1972 which reorganized local government. Secondly, the political and industrial unrest of the 1970s and early 1980s led to the establishment of new levels of national police co-operation and, in the words of one author, to the establishment of a 'de facto national police force'. Thirdly, increasing European influence has further internationalized police co-operation and organization. Johnston concludes that the spatial restructuring that appears to be taking place in British policing is indicative of a broader process of fragmentation of social structures and systems for maintaining order.

Attempts have also been made to locate security in the so-called 'policingdivision of labour' In order to understand this, it is necessary to identify some of the links which exist between public police organizations and the private security sector. Such links can be divided into six types : 1) Interpersonal links, 2) Joint operations, 3) Exchange of services, 4) Granting of special powers, 5) Public bodies hiring private personnel, 6) New organizational. Van Reenen provides a useful outline of the different dimensions of future Glibalization of policing. Developments, he suggests, are likely to proceed in four directions : 1) Co-operation : at this level, the nature and powers of national police systems are not required to change, co-operation occurring between self-standing forces. 2) Horizontal integration : this arises when officers obtain authority to operate in another country, or where government officials from one country get authority over the police in another country. 3) Vertical integration : this exists when a police organization is created which can operate within the area of the EC as a whole. 4) Competition : the internationalization of policing in Europe presents itself, more and more, as a market in which different policing systems trade their products.

Rapid advances in information and communications technology are new challenges and also opportunities for the police. For the purpose of identifying its implications, this study reviews utilization cases of information and communications technology in the field of public security in South Korea and other countries. As theoretical basis for utilization of information and communications technology, this study introduces intelligence-led policing, predictive policing and evidence-based policing. Also, utilization of big-data based crime analysis and crime prediction technology, as well as advancement of information and communications system and command and control technology of the police, are discussed. Based on the identified implications in this study, the following proposals are made. They are (1) procuring basic data, (2) creating an integrated database, (3) increasing utilization of policy decision-makers, (4) exchange and cooperation between related institutions, (5) training professional analyzers, (6) establishing legal basis and practical guidelines for an integrated database.
