This study proposes a model of collection process for real-time forensic data, in which the manager was to respond to infringement incidents in terms of system operation and inspection and to collect, analyze and restore forensic data immediately after an incident took place. The suggested model was modeled in seven processes according to functional elements. Unlike the old and managerial forensic processes, the model allowed the manager to react to infringement incidents in the aspects of system operation and inspection and to follow the processes of collecting, analyzing, and restoring forensic data in case of an incident. There also was a feedback process designed towards the step of gathering forensic data through the stages of systematizing reaction strategies in order that he or she be able to bring about comprehensive and structural responses to an incident like the former processes in which it is difficult to bring about instant responses.

Community roads pose risks for traffic accidents, falls, crimes, and disasters, threatening pedestrian safety. However, current road management and safety systems primarily focus on arterial roads, and fail to adequately consider the unique characteristics of community roads. This study presents a methodology to more effectively predict various pedestrian accidents on community roads by categorizing risk zones based on a distribution of risk factors. Through field surveys, key risk factors for each type of accident were identified, and the frequency of these factors was used to classify risk zones, which were then visually represented using GIS. Applying this methodology to Seoul's Seocho 1-dong, a comparison with actual accident data revealed a partial correlation between the predicted risk zones and actual locations of traffic and disaster-related incidents, thereby validating the methodology. This study is expected to serve as a policy tool for preventing accidents and enhancing safety on community roads.

This study aims to analyze safety indicators for various types of pedestrian accidents (traffic accidents, crimes, crowd crush incidents, and falls) in urban community roads. The need for this research arises from the complexity and narrowness of these streets, which significantly threaten pedestrian safety. The study employed literature reviews, case studies, and field surveys to identify risk factors for pedestrian accidents. These risk factors were then systematically evaluated using the Analytic Hierarchy Process (AHP) to determine the relative importance of each safety indicator. The analysis revealed that for traffic accidents, factors such as the separation of pedestrian and vehicle paths and the effective sidewalk width are critical. For crime-related incidents, lighting and CCTV coverage were found to be the most important. In crowd crush incidents, pedestrian traffic volume and effective sidewalk width were identified as key indicators, while slope and effective sidewalk width were crucial for preventing falls. These findings contribute to the development of targeted safety improvement measures for urban community roads.

A lot of fire and crime accidents are caused to a significant national loss. For example, the network and power facilities in national industry facilities, the fire risk region in large scale factories such as nuclear and thermal power plants, large-sized buildings, cultural properties, metal and steel mills, chemical plants, oil refineries. The development of a fire detection system that can detects the temperature and movement of objects as high-level quality is essential to prevent these incidents and accidents fundamentally. In this paper, the fire detection system based on infrared thermal imaging & CCD camera id designed to solve these problems.

Recently, as social anxiety regarding violent crimes accompanied by frequent occurrences of violence has increased, the need for intelligent video analysis in CCTV systems for crime prevention and rapid response to incidents has grown. One of the methods used for detecting violent behavior through video analysis is action-based detection using pose estimation. However, relying solely on joint angles and changes obtained from pose estimation to detect violent acts can lead to issues. False positives occur when non-violent actions such as petting a head or hugging are mistakenly classified as violent behavior. This study aims to reduce the frequency of false positives in action-based violence detection methods that utilize only pose estimation. We propose a new violence detection method that combines the results of facial emotion recognition (anger, disgust, fear, sadness, surprise, happiness, and neutrality) of the expected victim with the existing pose estimation-based violence detection method. By combining pose estimation with facial emotion recognition results on a video dataset consisting of YouTube videos and self-made videos, we were able to achieve a higher accuracy rate of 92.5% compared to the traditional method which solely relies on pose estimation. Future research will focus on studying violence detection in actual CCTV scenarios to improve the reliability of the result data.

Filmic spaces are not only a core expressive factors that can embody both internal and external meanings of films, but also play an important role for initiating dramatic context in terms of narratives. They establish visible environment in which provocative incidents occur and characters' behaviors are induced, include characters' psychology or emotional meanings of narratives and provoke tensions through symbolic meanings and the implicit function of surface background. This paper, therefore, analyzes the film, , by focusing on the dramatic function of narrative space. This film provides insights and thoughts through deep philosophical reflection, by escaping from the convention of such a genre, through deep philosophical reflection, by escaping from the convention of such a genre, though it belongs seemingly to the crime thriller genre using Mexico's drug cartel as it main material. In the film, narrative spaces are responsible for emotions invoking dramatic tensions beyond provocative incidents and the elaborately planned and controlled mise-en-scene absorbed audiences' attention by organizing ultimate suspense. In conclusion, flow and dramatic lingering imagery of this film might be achieved by power of scenes rather than plot factors. This study thus explained the correlation between narrative spaces and dramatic immersion, by analyzing spaces appearing in and visualized construction. It is hoped that this will further extends the pattern of researches on dramatic immersion, which have been primarily focused on plots and characters.

Financial Intelligence Unit Law doesn't include investigation on important cases that could influence the security and existence of the nation that are the core jobs of national intelligence agency. So the agency has a difficulty to investigate the international crime of North Korea and other security incidents. It is also difficult to catch an international crime organization working in Korea. It also produces problems such as difficulty in investigating the illegal leak of strategic materials and investigating people related to illegal funding to international terrorism. So it is urgently needed to revise Financial Intelligence Law as soon as possible. Foreign intelligence agencies use the information of financial intelligence unit in many different ways. National Security Agency of China and Australian Security Intelligence Organization freely use the information of financial intelligence unit based on their own laws and systems. Central Intelligence Agency and Federal Bureau of Investigation of USA and Secret Intelligence Service and Security Service of Britain request financial intelligence units to supply them with the information of financial intelligence unit. But the national intelligence agency of Korea isn't able to approach to FIU and can't share the FIU information with foreign intelligence agencies. To solve the problem, they should revise Financial Intelligence Unit Law so that national intelligence agency can receive or request information from Korean Financial Intelligence Unit.

As the post-cold war era and globalization go on, national security problems which were not traditional national security problems such as terrorism, crime, environmental disasters, economic crises, cyber-terrorism, diseases, and energy problems threat humanity and nations and demands changes. Also, with the change, the concept of "big government" has emerged as the role of nation expanded. The modern society sees every country change from small government to big government in order to realize the establishment of welfare state. A comprehensive interpretation of security is needed in order to comprehensive protection of citizens beyond outside invasion such as crime, new disaster, terrorism. In Korea, incidents such as Cheonan-Ham, Yeonpeyong-Do, foot-and-mouth disease, Ddos terrorism, pirates hostages, mad cow disease, AI are happening and the humanitarian support for North Korea and the summit of South and North Korea are at a standstill. Also, National emergency management system, comprehensive emergency management center, countrol tower, national security system, cooperation with citizens, establishment of legal and institutional system are needed. The importance of this research is on the reestablishment of new national security and emergency management system according to the comparison between the national security and counter-terrorism system of Korea and that of the United States which is a leading country in this field. Also, the establishment of national emergency management act is needed as a statute for effective function as currently various laws and administrative organizations are dispersed.
