Purpose : This study aims to develop the Forensic Nursing Competency Scale suitable to South Korea. Methods : The initial items were generated through literature review and interviews. Items were evaluated by experts for content and face validity. By conducting a pilot test, 74 measurement items were developed. In total, 333 copies of the questionnaire were analyzed regarding the validity and reliability of the study. Data were analyzed using SPSS 23.0 program and AMOS 18.0 program. Results : The study selected 53 questions after testing the content, face, and construct validity of the scale. The final 53 questions were composed of 15 sub-components in eight domains. These eight domains encompassed nursing practice, communication, critical thinking, human caring and relationships, evidence management, active information collection, professional development, and knowledge integration. Conclusions : In order to verify the effectiveness of the scale, future studies need to compare the forensic nursing competency in two groups to assess differences in these competency. Moreover, it is necessary to develop a forensic nursing educational program and validate its effectiveness by using this scale.

Purpose - This study aims to not only investigate spatial pattern of immigrants' residence and crime occurrences in South Korea, but shed light on how geographic distribution of immigrants and immigrant segregation affect crime rates. Research design, data, and methodology - Th unit of analysis is Si-Gun-Gu municipal level entities of South Korea. The crime data was obtained by Korea National Police Agency and two major types(violence and property) of crime were measured. Most demographic, social, and economic variables were derived from Korean Census Data in 2015. In order to examine spatial patterns of immigrants' distribution and crime rates in South Korea, the present study utilized GIS mapping technique and Exploratory Spatial Data Analysis(ESDA) tools. The causal linkage was investigated by a series of regression models using STATA. Results - Spatial inequality between urban metropolitan vs rural areas was visualized by mapping. Assuming large Moran's I value, spatial autocorrelation appeared to be quite strong. Several neighborhood characteristics such as residential stability and economic prosperity were found to be important factors leading to crime rate change. Residential distribution and segregation for immigrants were negatively significant in the regression models. Conclusions - Unlike the traditional arguments of social disorganization theory, immigrant segregation appeared to reduce violent crime rate and the high proportion of immigrants also turned out to be a crime prevention factor.

A fire broke out in a working wood-burning stove and destroyed an idyllic house about two years after it was built. This study analyzed data provided through the court by the fire station, police station, fire insurance investigation agency, house construction company, and wood-burning stove maker Based on the fire pattern of low-temperature long-term ignition that remained in the studs, the fire was found to be caused by the conduction of heat in the fire box to the studs of the wall next to the wood-burning stove. A fire simulation showed that the low-temperature long-term ignition of the studs next to the wood-burning stove occurred because a hole was not made for ventilation in the chimney.

PURPOSES : The purposes of this study are to compare the day and night characteristics and to develop the models of traffic accidents. in Rural Signalized Intersections METHODS : To develop day and night traffic accident models using the Negative Binomial Model, which was constructed for 156 signalized intersections of rural areas, through field investigations and casualty data from the National Police Agency. RESULTS : Among a total of 17 variances, the daytime traffic accident estimate models identified a total of 9 influence factors of traffic accidents. In the case of nighttime traffic accident models, 11 influence factors of traffic accidents were identified. CONCLUSIONS : By comparing the two models, it was determined that the number of main roads was an independent factor for daytime accidents. For nighttime accidents, several factors were independently involved, including the number of entrances to sub-roads, whether left turn lanes existed in major roads, the distances of pedestrian crossings to main roads and sub-roads, lighting facilities, and others. It was apparent that if the same situation arises, the probability of an accident occurring at night is higher than during the day because the speed of travel through intersections in rural areas is somewhat higher at night than during the day.

Crimes with explosives is one of the mass-destructive crimes that involves the most victims. It is heavily punished under the Korean laws. Mid-eastern area is one of the leading places that are home to improvised explosive device attacks, in the form of religious or political terrorism because of its convenience of use, production and disguise. Improvised bombs are permeating into domestic crimes in Korea as their tools. Use of explosive substances are strictly restricted in this country, but it is not impossible to find its information online and to create private explosives with a bit of interest. And they are being traded in the grey market. For this reason, this thesis offers the method of an efficient safety control of explosive substances, which can be used as raw materials for improvised explosive devices, in order to protect citizens' lives and properties and to promote national security down the road.

This study aims to analyze operation status of the professional fire investigation education in Korea and derive improvement measures. Study results showed that professional fire investigation educations are conducted mainly by public sectors (Fire Service, Police, Korea Electrical Safety Corp, Korea Gas Safety Corp, etc.) and the educations conducted by National Fire Service Academy are most systematic. In addition, there was no professional fire investigation educations conducted for private sector (fire accident suffers, common peoples, etc.) In order to improve the problems, this study suggests changing the National Fire Service Academy to lifelong education system in coordinance with the scholar's courses of universities, classifying the fire inspector qualification course (executed by National Emergency Management Agency) in five stages, and opening the fire inspector qualification test to the public.

An unmanned aerial vehicle(UAV), commonly known as a drone, is an aircraft without a human pilot aboard, which is operated by wireless device. A drone provides the capability for the aerial search and traffic control as a police equipment. It has benefits for the missions for the aerial photography with the high resolution camera which can replace eye-dependent search processes. Moreover it has advantage of retrieving several times for the recorded videos. However, if the law enforcement agency misuse and overuse a drone for investigations and search missions without certain regulations and principles, it breaches privacy and personal information infringement. In this paper, we issue a lawful challenges on drone operations and discuss solutions to those challenges.

When a crime occurs, the information necessary for solving the case, and various pieces of the evidence needed to prove the crime are collected from the crime scene. The tangible residues collected through scientific methods at the crime scene become evidence at trial and a clue to prove the facts directly against the offense of the suspect. Therefore, the scientific investigation and forensic handling for securing objective forensic in crime investigation is increasingly important. Today, digital systems, such as smartphones, CCTVs, black boxes, etc. are increasingly used as criminal information investigation clues, and digital forensic is becoming a decisive factor in investigation and trial. However, the systems have the risk that digital forensic may be damaged or manipulated by malicious insiders in the existing centralized management systems based on client/server structure. In this paper, we design and implement a blockchain based digital forensic management model using Hyperledger Fabric and Docker to guarantee the reliability and integrity of digital forensic. The proposed digital evidence management model allows only authorized participants in a distributed environment without a central management agency access the network to share and manage potential crime data. Therefore, it could be relatively safe from malicious internal attackers compared to the existing client/server model.
