Since the terrorist attacks 9.11 in 2001, the public places such as subway, department stores or office buildings have become a target of terror in major public facilities. In this paper, for the prevention of terrorist attack in domestic building, the assessments of terror risk were conducted and their relationship with building heights was discussed through FEMA 455-Rapid Visual Screening(RVS). Explosive terror risk tends to increase rapidly with building heights(H<230m), showing the correlation coefficient between total risk and building heights(H<230m) is 0.93. In addition, The average of consequences is 8.47 and that of' threat is 8.95. Vulnerability is found to be 6.62 in average.

According to the global status of terroristic acts occurred from 2002 to 2010, 10,431(nearly 52.2%) of 19,946 cases have happened by bomb blasts, and 10,431(nearly 52.2%) of weapons used for terrorism were explosive substances Therefore, this study analyzed the terrorism risks of buildings according to height through FEMA 455 - rapid visual screening. As a result, the higher the building is, the higher the terror risk gets. It shows that total risk increases proportionally to buildings's height. In case of buildings over 100 meter high, the total risk is most affected by threat items. According to the risk of explosion associated with the scenario analysis, buildings over 100 meter high have high risks of Internal-Explosive.

Since the destruction of World Trade Center the attention of the United States and the wider international community has focussed upon the need to strengthen security and prevent terrorism This paper suggests an analysis prior to risk factor and structure for anti-terrorism in the korean maritime society. For this, in this paper, maritime terror risk factor was extracted by type and case of terror using brainstorming method. Also, risk factor is structured by FSM method and analyzed for ranking of each risk factor by AHP. At the result, the evaluation of risk factor is especially over maximum factor for related external impact.

While frequency of occurrence of terrorism has recently increased, it intensively occurs in buildings that many unspecified persons gather. Terrorism which occurs in high-rise buildings causes a lot of damage. It is necessary for design approach to reduce terrorism damage from explosive of buildings. Terror risk analysis of domestic tall and high-rise buildings is evaluated by fema 455, Rapid Visual Screening which is found to be comparatively simple and practicable. Common risk factors of terrorism in domestic buildings were investigated. The results of terror risk assessment of all buildings are found to be a medium risk score, Main reason is that domestic tall or high-rise buildings have similar external-environmental factors.

The purpose of this research is to explore the effective response methods for the prevention of cyber-terror in South Korea. This research used an analysis of literature research. From the result of this research, the researchers suggested 1) enactment of the 'Cyber-terror Prevention Act' in order to enhance the effectiveness against cyber-terror; 2) establishment of practical control tower for cyber-terror; 3) expansion of the expert training for cyber-terror. The limitations of this research and the recommendations for future research were discussed at the last part of this research.

Since the end of the Cold War and rapid globalization and technical developments, terrorist groups actively involved in criminal activities. Also criminal entrepreneurs became a major financial revenue for these terrorists groups. This newly patternized activities among terrorist groups is now called as Crime-Terror Nexus" indicating the changing nature of terrorism, which means two traditionally separate phenomena, crime and terrorism, became more similar. This new pattern of terrorism is considered to create synergy for the criminal organizations and terrorist groups, scholars believe that it would become a significant threat to the security of world community in the near future. Although the phenomenon of this crime-terror nexus is significant and imminent threats, there is lack of studies investigation this new evolution of terrorism with empirical data. Moreover there is literally no studies exploring factors relevant to the Crime-Terror Nexus. Therefore, this current study aims to conduct explorative investigation of factors affecting the "Crime-Terror Nexus" with a world terrorism data, MAROB(the Minorities at Risk Organizational Behavior), which is developed by START and Minority at Risk project and contains information terrorist groups in Middle-East and Africa region. Considering the significance of this new terrorism patterns and the challenging nature of conducting empirical studies on this topic, this study has great contribution on the development in the field of criminal justice as well as terrorism.

As the occurrence rate of terror and hazard is increasing throughout the world, GSA, DoD, and FEMA are proceeding a study about mitigating the damage of terror. Korea is no more a safe place from the terrorist's threat, so we need to make measures against them. In this study we developed modified RVS System by revising some items to adjust the system to the domestic condition and conducted a risk assessment on several tall buildings in Korea. By using IRVS system which is developed by DHS, we also carried out the risk assessment. Comparing the results between RVS with IRVS, we performed terror risk evaluation of tall buildings. Through risk assessment of several tall buildings, we analyzed key factors of each scenarios and suggested the mean value of each items, so we would like to help the counter-terrorism in the design phase.

In recent years, cyber terror that break into major institution's information system and destroy and paralyzed important information occurs frequently. Some countries do dangerous acts such as train hackers and order hackers to hack important industrial confidential documents which are core of national competitiveness to reduce the competitiveness of the country and cause social confusion. In this thesis, it will study problems of cyber terror to help people to use Internet in web environment that safe from cyber terror and to avoid the risk from cyber terror such as malware and DDos. This thesis is organized as following. In second chapter, it will look thorough the research that are related to cyber terror. In third chapter, it will study attack types of cyber terror. In fourth chapter, to defend from cyber violence, it will suggest safe solution. In fifth chapter, it will end with conclusion. Finally, to prevent urgent incidents like North Korean Cyber-attack, every Internet user must indicate their recognition on Internet security and it is significant to make a quick response treatment to create the safe online environment.

Since the 1980s, the number of large space buildings in Korea has consistently been increasing due to large scale international competitions such as the Olympics and the World Cup, demands for environmental improvement, and development of structural systems. Due to these reasons, this paper conducted a comparative analysis on terrorism risk factors of large space structure and skyscrapers in Korea. The results suggest that the total risk level of high-rise and large space structure was "medium level risk" and that the terrorism risk level for large space structure was as high as that for high-rise buildings. As it relates to the risk levels depending on scenarios, terrorism risks to large space structure were higher than high-rise buildings in the "internal explosion" and "internal intrusion" categories. And the results of analyzing explosion-related scenarios except for CBR suggest that terrorism risks to large space structure were highest when it comes to Internal-Explosive followed by Internal-Intrusion and Explosive-Zone I; and the results showed a regular pattern. On the other hand, in the case of high-rise buildings, terrorism risks were highest in Internal-Explosive followed by Explosive-Zone I and Explosive-Zone II; and the results showed an irregular pattern.
