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.

The primary aim of this study is to provide effective operational directions of multi-purpose maneuver patrol via practical analysis on the fear of crime and its impact factors in the Hot Spots Policing target region. Comparative Analysis on fear of crime and its impact factors such as informal social control, disorder, and the perception of police activities is conducted in regions of maneuver patrol against its neighborhood. In Conclusion, no evident differences in fear of crime between the regions of maneuver patrol and its neighborhood were found. However, regions of maneuver patrol displayed significant distinctions in informal social control and perception of crime frequency in comparison to its neighborhood of no such patrol. In addition, it was noticed that in both regions disorder and perception of crime frequency served as the impact factors of fear of crime, which in part exhibits positive relationship with perception of hot spots policing. This study concludes that criterion in deciding on the regions of maneuver patrol should include subjective impact factors such as fear of crime. Furthermore, it suggests that along with the current unsatisfactory maneuver patrol system there needs specific guideline to enhance the perception of police activities including strengthened interactions with residents, improvement in social disorder.

In 2003, the local police system was adopted, and the personnel and installation of local police agencies were subsequently changed. According to the "Police Law", local police station shall be established under the control of chief of police department, and the criteria for the installation of local police stations were to take into consideration of population, administrative districts, area, geographical characteristics, traffic and other conditions. The chief of local police has the authority to install district police station according to the "National Police Agency and its Organization". However, it is hard to say they were applied. Futhermore, it is inappropriate to apply the laws and regulations equally across the nation. Also, it has been criticized for its difficulties of patrolling, the weakened relationship with local residents, and poor quality of security services in rural areas. Therefore, this study suggests that the criteria for the installation of the police station should be made through a comprehensive analysis of the characteristics of the areas and security needs.

한국도 더 이상 총기안전지대가 아니며, 강력범죄도 지속적으로 증가하고 있는 상황에서 경찰관의 신체 생명을 적극적으로 보호하면서 무기 사용을 최소화 할 수 있도록 경찰관 장비에 대한 개선점이 필요하다. 장비에 대한 지급이 미흡한 시점에서 경찰관의 안전과 치안유지를 담당하기 위해서는 장비에 대한 보급과 착용이 우선적으로 진행되어야 하며, 경찰 출동차량에 반드시 방탄복, 방검복, 방검장갑, 안전헬멧 등을 필수 배치해서 범죄현장에 대처해야 한다.

오늘날의 경찰활동의 가치는 범죄통제에 초점을 두는, 즉 범죄진압을 강조하는 사건지향적인 경찰활동이라 할 수 있는 전통적인 경찰활동에서 순찰 등의 강화를 통한 범죄예방에 중점을 두는 지역사회 경찰활동으로 그 중심이 옮겨가고 있다. 이러한 지역사회 경찰활의 철학을 실천하는 전략으로서 문제지향적 경찰활동이 강조되고 있다. 이에 본 연구에서는 도시범죄와 관련하여 현실적으로 범죄문제에 대응할 수 있는 범죄예방전략인 문제지향적 경찰활동의 이론적인 틀을 모색하고자 하는데 연구의 목적을 두었다. 이를 위해 문제지향적 경찰활동의 기본적인 개념과 특징, 그리고 문제지향적 경찰활동 실천의 핵심인 SARA모델과 사례를 살펴보았다.

The study aims to analyze the factors affecting citizens' willingness to cooperate in police activities and to verify the intermediation effects of citizens' trust in police in these relationships. In order to achieve the purpose of such research, we selected factors that are expected to affect cooperation in police activities and police confidence by conducting a survey of 502 adult men and women living in Seoul and utilized them for analysis. The results from the analysis are summarized as follows. First, procedural fairness was confirmed as an influence factor on the cooperative history of police activities. In other words, it is necessary to have police activities conducted more fairly and citizens recognize them in order to induce cooperation from citizens, as the fairer police activities are shown to increase the willingness of citizens to cooperate. Second, it was confirmed that the level of citizen awareness of patrol activities and level of disorder in the community affected cooperation in police activities through the medium of police trust. It can be said that the more positively citizens evaluate police patrol activities, the more police confidence increases and this trust leads to citizens' cooperation in police activities. In addition, as the disorderly environment in the community improves, citizens' trust in the police increases, leading to civic cooperation in police activities. Based on this, the police trust was able to confirm that it had a fully operational effect. Third, if the procedural fairness of police activities increases, citizens trust the police, and this police trust leads to cooperation in police activities. In addition, it was found that procedural fairness had a direct impact on citizens' cooperation in police activities, so it was able to confirm that there was a partial selling effect.

In recent years, use of machine automation is rising in the industry. Ships also obtain machine condition information from sensor as digital information. However, on ships, crew members regularly surveil the engine room to check the condition of equipment and their information through analog gauges. This is a time-consuming and tedious process and poses safety risks to the crew while on surveillance. To address this, engine room surveillance using an autonomous mobile robot is being actively explored as a solution because it can reduce time, costs, and the safety risks for crew. Analog gauge reading using an autonomous mobile robot requires digitization for the robot to recognize the gauge value. In this study, image processing techniques were applied to achieve this. Analog gauge images were subjected to image preprocessing to remove noise and highlight their features. The center point, indicator point, minimum value and maximum value of the analog gauge were detected through image processing. Through the straight line connecting these points, the angle from the minimum value to the maximum value and the angle from the minimum value to indicator point were obtained. The obtained angle is digitized as the value currently indicated by the analog gauge through a formula. It was confirmed from the experiments that the digitization of the analog gauge using image processing was successful, indicating the equivalent current value shown by the gauge. When applied to surveillance robots, this algorithm can minimize safety risks and time and opportunity costs of crew members for engine room surveillance.

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.
