This study examines the degrees of criminal investigators' job satisfaction and organizational commitment and investigates which factors determine the variations in them. In the first step of analysis, independent variables of criminal investigators' job satisfaction consist of work itself, achievement, responsibility, safety, stability, interpersonal relations, recognition, supervision, and opportunity of growth. In the second step, job satisfaction is a mediating variable and organizational commitment is a defendant variable. Organizational commitment is classified into three types - "affective", "continuance" and "normative". According to the structural equation model analysis, responsibility has a great influence on job satisfaction, and job satisfaction affects affective commitment and continuance commitment. This study suggests that job satisfaction should be increased to improve criminal investigators' organizational commitment. And responsibility is necessary for the improvement of job satisfaction. Despite the professional detective system operating in Korea since January 1, 2005, the level of criminal investigators' recognitions of safety, stability and opportunity of growth turn out to be low. Based on these findings, this study presents four ways to reform measures which are listed below. First, to improve a! n economical circumstance of criminal investigators, any expense associated with criminal investigation should be paid by organizations. Second, to improve safety of criminal investigators, it is necessary to develop and supply enough police equipments. Third, criminal investigators' working hours should be shorten. Fourth, to improve criminal investigators' responsibilities, criminal investigators should be allowed to conduct criminal investigation independently from the prosecution.

The reason why rhetoric is important to a moving image is that a moving image communicates through non-verbal communication language. At first, rhetoric in a moving image functions to be persuasive in the story of a moving image. Second, rhetoric works to enhance an aesthetic value for a moving image. Thus we feel good when we are watching a moving image with well embeded rhetoric. On the other hand, we see extened rhetoric to enhance an imaginary because of a hollywood movie with visual effect and a digital movie. Visual images now formed using more signigier compared to signified for signification. Also we see that every signifier structured metaphorically to function as a sign. In this paper, 1 am going to explain the principles of rhetoric applied to a moving image so that we can better understand a signification on visual image.

In recent years, as smart phone penetration rate is growing explosively, new forms of cyber crime data is poured out beyond the limits of management system for cyber crime investigation. These new forms of data are collected and stored in police station but, some of data are not systematically managed. As a result, investigators sometimes miss the hidden data which can be critical for a case. Crime data is usually generated by computer which produces complex and huge data and records many logs automatically, so it is necessary to simplify a collected data and cluster by crime pattern. In this paper, we categorize all kinds of cyber crime and simplify crime database and extract critical clues relative to other cases. Through data mining and network-visualization, we found there is correlation between clues of a case. From this result, we conclude cyber crime data mining helps crime prevention, early blocking and increasing the efficiency of the investigation.

There are so many study on Heumheum Sinseo as a lawbook. But the study on Heumheum Sinseo as investigation and forensic manual is uncommon. So this study was performed to find the value of Heumheum Sinseo as investigation and forensic manual. In Heumheum Sinseo, we could find the basic ideology of a sense of justice on humanitarianism and rationalism, and democratic thoughts on criminal law such as the presumption of innocence, speedy investigation clause and Limiting the admissibility of the confession. And so many scientific method on crime investigation are described in Heumheum Sinseo. We expect that this study serve as moment for us to be able to find it have 'practical' value to us.

Recently, the use of ATV (All-Terrain Vehicle) has increased due to increase in leisure activities, and the awareness of safety and traffic accidents has improved, but it still insignificant compared to other transportation. Therefore, in this study, the current status and characteristics of traffic accidents related to ATVs were investigated, and actual ATV accident was analyzed. As a result, it was confirmed that the condition of the braking system directly connected to the safety of the ATV was not well maintained. For driver safety in the future, it is considered that it is necessary to strengthen safety regulations related to experience centers and rental companies handling AVTs and to conduct regular inspections in accordance with the Motor Vehicle Management Act.

급변하는 현대사회에서 각종 범죄가 고도로 지능화, 전문화 되고 있을 뿐 만 아니라 매년 범죄율이 증가하고 있다. 범죄수사에서 범죄자를 검거하기 위해서는 '골든 타임'인 초기 단계가 가장 중요하다. 따라서 CCTV를 일일이 돌려보던 기존의 비효율적인 수사방식이 아닌, 얼굴인식기술을 활용해 골든타임 안에 범죄자를 검거 할 수 있도록 도와주는 얼굴인식기반 범죄수사 시스템을 제안한다. 얼굴인식 프로그램을 사용하여 CCTV 영상 속 범죄자가 있다면, 곧바로 얼굴을 인식해 표시 해줌으로써 단시간 안에 범죄자의 이동경로를 파악한다. 이후 이동경로 및 수사정보를 웹페이지를 통해 다른 경찰관들과 공유해 범죄자를 빠르게 검거하는 시스템을 제작하였다. 제작과정에서 얼굴인식관련 기술은 Deep Metric CNN(triplet), Resnet, Knn classification을 사용해 python으로 구현하였다. 통신을 위한 웹서버는 Bitnami를 통해 구축했으며, NAT, DHCP, Port Fowarding 기술을 사용했다. 마지막으로 웹페이지는 HTML, PHP, CSS 등을 통해 제작해 수사정보를 주고 받을 수 있게 제작하였다.

This study will show the digital forensic model which fights against cyber-crimes to prepare various cyber-crimes. The digital forensic model will be more useful about the investigation of cyber-crimes and arresting criminals after researching the uses of the digital forensic model and cyber-crime rates in South Korea. This model conduct the standardized data with various languages by the language support system through the digital forensic analyzer. This model will send the data to law enforcement reviewing whether or not we ought to prove criminal charges. Moreover, law enforcement can access the file system to find out admissibility of evidence. And this model simplifies lawful investigation about additional investigation. The data, which is conducted and saved by the digital forensic system, will be helpful to protect against the future crimes because of the data.

수사구조는 텍스트의 각 구성 성분이 맺고 있는 관계를 의미하며, 필자의 의도는 논리적인 구조를 통해서 독자에게 더 잘 전달될 수 있다. 따라서 독자의 인지적 효과를 극대화할 수 있도록 수사구조를 고려하여 단락과 문장 구조를 구성하는 것이 필요하다. 그럼에도 불구하고 지금까지 수사구조에 기초한 한국어 분류체계를 만들거나 주석 코퍼스를 설계하려는 시도가 없었다. 본 연구에서는 기존 수사구조 이론을 기반으로, 한국어 보도문 형식에 적합한 30개 유형의 분류체계를 정제하고 최소 담화 단위별로 태깅한 코퍼스를 구축하였다. 또한 구축한 코퍼스를 토대로 중심문장을 비롯한 문장 구조의 특징과 분포 비율, 신문기사의 장르적 특성 등을 살펴봄으로써 텍스트에서 응집성의 실현 양상과 구문상의 특징을 확인하였다. 본 연구는 한국어 담화 구문에 적합한 수사구조 분류체계를 설계하고 이를 이용한 주석 코퍼스를 최초로 구축하였다는 점에서 의의를 갖는다.

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.
