A new urban paradigm that moves from a vehicle-centric to pedestrian-centric culture should be considered to improve the quality of the pedestrian environments for women, children, senior citizens, and disabled persons as well as to promote community unification by providing general movement rights to everyone. This study was implemented to provide decent alternatives to improve street spaces. The street spaces around the Commercial and Residential Area No.1 located in the Administrative-Centered City, Sejong Special Autonomic City, were selected to analyze and define the status of the walkways and the street spaces. Satellite imagery and numerical maps were used to collect geographic data. Practical and actual surveys for the selected sites were performed to analyze the street status and the pedestrian status. Based on the all collected data, analysis results, and literature reviews, the questionnaire was made, and 315 inquiries qualified for analysis. The physical status of all four study sites was the highest level, Grade A, and green open spaces were relatively sufficient. As a result, the factors obtained from the factor analysis have an impact on the satisfaction of the pedestrian streets in the commercial area. The factors are as followed Design > Convenience > Roadside trees and rest areas > Safety > Safety protective facilities > Transportation and information facilities > Continuity > Basic state of road surfaces > Comfortability, and in the residential area: Transportation and information facilities > Basic state of road surfaces > Comfort > Convenience > Continuity > Design > Illumination and crime prevention facilities > Safety > Roadside trees and rest areas.

This study is aimed to improve the youth theft prevention program with rationality and practicality, based on the needs of practitioners who conduct these programs in fields. The survey questionnaire was prepared based on previous researches, and the survey was conducted on 72 probation officers and education instructors nationwide running a youth theft prevention program. As a result, practitioners reported the lack of self-control and high impulsivity as the main characteristics of the theft delinquent adolescents. And they recognized peer alignment and family problems as the causes of theft. As for the contents of the program, they reported that recidivism prevention skills such as understanding psychological problems, peer relationships, raising a sense of law compliance, anger, impulse control, dealing with negative emotions, and finding alternative behaviors, as well as moral development, are necessary. These results indicate that multi-dimensional interventions such as individuals, families, and peers are needed to prevent recidivism of juvenile theft. Implications of these results, future research directions, and limitations and significance of the study were discussed.

The court in Korea values evidence justice, and also demands justification for the process of collecting evidence. Therefore, it is necessary to raise the level of organizational commitment, which means that the police investigators performing these tasks feel attached to the police organization they belong to, and that they feel united about the goals of the organization. Based on this recognition, the study analyzed the effects of the police's perception of organizational Justice on organizational commitment, and classified organizational Justice into distributive Justice, procedure Justice and interaction Justice. Therefore, this study analyzes the effect of the police's perception of organizational Justice on organizational commitment and verifies the effect through multiple regression analysis by injecting the trust of Supervisors into a mediating variable. The study was also conducted on the assumption that the trust of Supervisors is important in carrying out the field investigators work in the South Korean police. To achieve the purpose of this research, a total of three surveys were conducted from May 2017 to October 2019 at the National Police Agency using the selection process of investigators and job training courses for the national police, and a total of 500 copies were used as analysis data. Looking at the results analysis of this study, first, it was found that there was a statistically significant static (+) effect on organizational commitment, where the organizational Justice of police officers was a independent variable. Second, the relationship between organizational Justice and organizational commitment has shown that the trust of Supervisors has a mediating effect in korean police organization.

Purpose of this study is to analyze actual perception of security business of security workers centering on employees working within building and to improve accomplishment of works for security workers. For this, first, activities of security workers are discussed. Second, perception of employees of companies for the necessity of security workers, non-necessity of security workers, qualification requirements of security workers for improving business recognition were established as a framework of the study. Changes for recognition of security works in modern life are a little falling behind compared to unstopping economic development and diversifying job classifications. Even at present, expression of security works is still regarded as manager of facilities or apartments in the past. In other words, it is recognized as a simple change of title and names from apartment guard to security workers. Security works in the modern job classification is settling down as a professional field of facility management and as a part of various controls such as protection and security and its field is also expanding. It is a professional job with the purpose to analyze and prevent diverse criminal actions occurring in the society and also to introduce alternative measures with the role to prevent accidents to be occurred in variety in advance instead of simple working format taking a fixed guard post. Area of security works for the purpose of maximizing necessity of security works shall have equipped with deployment of professional security workers, consideration of business satisfaction of security workers, prevention education for rapidly changing safety accidents, and substantiality in the field. We expect to have more sophisticated area of security works with ceaseless efforts and with instillation of recognition of professionalism by security workers themselves.

Photography is the most commonly used method of documenting the crime and incident scene as it helps maintaining chain of custody (COC) and prove integrity of the physical evidence. It can also capture phenomena as they are. However, digital images can be manipulated and lose their authenticity as admissible evidence. Thus only limited techniques can be used to enhance images, and one of them is Fourier transform. Fourier transform refers to transformation of images into frequency signals. Fast Fourier transform (FFT) is used in this study. In this experiment, we overlapped fingerprints with graph paper or other fingerprints and separated the fingerprints. Then we evaluated and compared quality of the separated fingerprints to the original fingerprints, and examined whether the two fingerprints can be identified as same fingerprints. In the case of the fingerprints on graph paper and general pattern-overlapping fingerprints, fingerprint ridges are enhanced. On the other hand, in case of separating complicated fingerprints such as core-to-core overlapping and delta-to-delta overlapping fingerprints, quality of fingerprints can be deteriorated. Quality of fingerprints is known to possibly bring negative effects on the credibility of examiners. The result of this study may be applicable to other areas using digital imaging enhancement technology.

Recently, the use of digital media such as computers and smart devices has been rapidly increasing, The vast and diverse information contained in the warrant of the investigating agency also includes the one irrelevant to the crime. Therefore, when confiscating the information, the basic rights, defense rights and privacy invasion of the person to be seized have been the center of criticism. Although the investigation agency guarantees the right to participate, it does not have specific guidelines, so they are various by the contexts and environments. In this process, the abuse of the participation right is detrimental to the speed and integrity of the investigation, and there is a side effect that the digital evidence might be destroyed by remote initialization. In this study, we conducted surveys of digital evidence analysts across the country based on four domains and thirty measurement items for enabling environment for participation in information storage media export and digital evidence search process. The difference between the level of importance and the performance was analyzed by the IPA matrix based on process, location, people, and technology dimensions. Seven items belonging to "concentrate here" area are one process-related, three location-related, and three people-related items. This study is meaningful to be a basis for establishing the proper policies and strategies for ensuring participation right, as well as for minimizing the side effects.
