Online cybercrime has various causes. The criminal guilty language, Criminal lingo is active in the shaded area with the bilateral aspect of the word on cyber. It has been continuously producing massive risk factors in cyberspace. Criminals are shared and disseminated online. It has been linked with fake news and aids to suicide that has recently become an issue. Thus the criminal lingo has become a real danger factor on cyber interface. Recently, Criminal lingo is shared and distributed as cyber hazard information. It is transformed that damaging to the youth and ordinary people through the internet and social networks. In order to take action, it is necessary to construct an expert system based on AI to implement a smart management architecture with block-chain technology. In this paper, we study technically a new smart management architecture which uses artificial intelligence based decision algorithm and block-chain tracking technology to prevent the spread of criminal lingo factors in the evolving cyber world. In addition, through the off-line regular patrol program of police units, we proposed the conversion of online regular patrol program for "cyber harem area".

The changed environment on marine security and the security activities such as coast guard and sea patrol in civil domain are analyzed. In order to respond diverse threats and requirements of sea petrol, the system of civil patrolman and coast guard's auxiliary are discussed. The civil boats and aircraft and civilian's security activities make an important role to enhance the effectiveness and the efficiency of coast guard and patrol.

A study on America Police-Private Security Partnership in Business Improvement Districts, Special Event Safety and Security, Community Policing, Alarms, Investigations, Electronic and Financial Crimes Investigations. Many Police-Private Security Partnerships have significantly changed how policing is done with respect to field operations, particularly patrol and access control. Some areas in which these collaborations have produced notable results are described here.

The tourism police force has been established on 16th October 2013 for foreign tourists' safety and security. The major roles of tourism police officers were provided a crime prevention patrol and maintenance of order in tourist destination, a clampdown on illegal activities for foreign tourists, a controlling for overcharging of restaurants accommodations taxi, an administrative guidance and controls on tourism industry and worker in union relative organ like the Ministry of Culture, Sports and Tourism local government. However, the roles of tourism police officers overlap the work of general police officers and work of tourism police officers need a cooperative business with relative organs. It is caused a role ambiguity conflict between tourism police officers and general police officers. The object of this study is to improve the tourism police system through investigate a perceived gap of role ambiguity conflict between tourism police officers and general police officers and influencing relationship of role ambiguity conflict between job Satisfaction and job Performance.

Recently, the use of information and communication technology (ICT) has advanced activities in the field of policing, such as police training, crime investigation, and on-site response equipment enhancement. In this paper, we examine how to use immersion technology in the field of policing. Currently, AR/VR technology is mainly used for police education, training, and criminal investigation, and other cases of its use are rare. To use AR/VR technology in a wider range of applications, it is necessary to look at how it can be used in major police activities (e.g., patrol, investigation, and arrest activities).

Recently, there are many real life applications that uses drones. There are various applications such as the aerial shot with the drones for the broadcasting service or drone racing competition and so on. Specifically, they patrol for the traffic enforcement on a highway. The police department use the 'Spot Mobility' method which float the drones for 30 minute period. However, this method is inefficient for the wide area with small numbers of enforcement. Therefore, a wireless network system consists of drones to patrol on the highway systematically is required. In this paper, the most efficient routing protocol will be selected for the MANET drone network by applying various routing protocols. To accomplish this, the drone patrol network system with routing protocols are designed and simulated in OPNET simulator.

Since year 2016, in Korea, the police department started to use drones to patrol violated vehicles on the highway area. They monitor vehicle drivers who use side ways on the highway during traffic congested hours of the season, drunken drivers, or violent drivers. They use the 'Spot Mobility' method which floats the drones for 30 minute period. However, this method is inefficient since it requires manually charging batteries, gathering data, and operate drones with many numbers of policeman. Therefore, in this paper, for the efficient patrol in this purpose, I have suggested an effectively manageable network system consists of many drones as the wireless network nodes and with small numbers of policeman in a wide highway area. To accomplish this, the two topologies of effective drone patrol network systems are designed and simulated in OPNET simulator for performance evaluation.

In the present study, the distribution of glass particles inside 10 patrol cars of Chungnam Province has been studied. The target seats were front seats (driver’s seat, passenger’s seat) and the back seat. The target areas were the bottom of the seat (seat contacting buttocks, back of the seat, and the corner of the seat (the bottom and back attached part)). The target areas were tape lifted with an adhesive tape. The glass particles adhering to the adhesive tape were examined and counted under a stereomicroscope. The total number of glass particles found was 679. Among them, 471 (driver’s seat 293, passenger seat 178) were collected from front seats, which are usually occupied by police officers. The majority of glass particles were under 0.49 mm size. The results show that the majority of glass particles can be found on the front seats, rather than on the back seat. There is a high probability that glass particles found on the front seat adhere to police officers, so that to get further transferred to the convict upon physical contact (secondary transfer). Thus, there is a risk of misinterpretation of the value of glass evidence in the course of forensic examinations. Hence, a separate method to prevent cross contamination has to be prepared by police authorities as soon as possible.
