  • In general, the industrial complex is a place where factories of various industries are concentrated. It is only as efficient as it is designed. However, the risks vary as there are various industries. These features are also associated with various types of disasters. The dangers of natural disasters such as a typhoon, flood, and earthquake, as well as fire and explosions, are also latent. Many of these risks can make stable production and business activities difficult, resulting in massive direct and indirect damage. In particular, decades after its establishment, the vulnerabilities increase even more as aging and small businesses are considered. In this sense, it is significant to assess the vulnerability of the industrial complex. Thus analysing fire and explosion hazards as stage 1 of the vulnerability evaluation for the major potential disasters for the industrial complex. First, fire vulnerabilities were analyzed quantitatively. It is displayed in blocks for each company. The assessment block status and the fire vulnerability rating status were conducted by applying the five-step criteria. Level A is the highest potential risk step and E is the lowest step. Level A was 11.8% in 20 blocks, level B was 22.5% in 38 blocks, level C was 25.4% in 43 blocks, level D was 26.0% in 44 blocks, and level E was 14.2% in 24 blocks. Levels A and B with high fire vulnerabilities were analyzed at 34.3%. Secondly, the vulnerability for an explosion was quantitatively analyzed. Explosive vulnerabilities were analyzed at 4.7% for level A with 8 blocks, 3.0% for level B with 5, 1.8% for level C with 3, 4.7% for level D with 8, and 85.8% for level E with 145. Levels A and B, which are highly vulnerable to explosions, were 7.7 %. Thirdly, the overall vulnerability can be assessed by adding disaster vulnerabilities to make future assessments. Moreover, it can also assist in efficient safety and disaster management by visually mapping quantified data. This will also be used for the integrated control center of the N-Industrial Complex, which is currently being installed.

  • In the case that high-rise building is constructed, the surrounding wind velocity increase more than 50~100%. From this cause, many wind environmental problems can be occurred. For example, ordinary wind environmental disaster may be occurred in a region, or walking disturbed. In developed countries including USA, EU, and Japan, many efforts have been made for building wind prevention by grasping previously the effects before building constructed. But, We are bearing risk of wind environmental disaster because we have not enough recognition about building wind, and have not architectural prevention counterplans. This study aims to examine wind environmental characteristics of domestic apartment complex, and effective architectural counterplans. As the basic stage for this, we investigated pre-estimate tools and risk assessment methods of building wind in apartment complex, applied to two apart complex in Cheon-An region by CFD. As the result, serious damages were not presented. But, it is obvious that various architectural counterplans will be presented by this example researches.

  • Objective: This study was designed to report on the progress of the fire at Jecheon sports complex and to assess the adequacy of Disaster Medical Assistant Team (DMAT)'s activities in response to the fire disaster. Methods: We conducted a retrospective review based on camera recordings and medical records that were recorded at the disaster site for assessment of activities. We cooperated with firefighters, police officers, local hospital medical staffs and public health personnel in Jecheon in order to classify patients in the disaster field and to understand the patients' progress. Results: At 15:53, the first request for emergency rescue came to the 119 general emergency call center, and a request for DMAT activation came at 16:28. DMAT arrived at the site at 17:04 and remained active until the following day at 00:43. The total number of casualties was 60, including 27 minimal (Green) patients, 29 expectant (Black) patients, three delayed (Yellow) patients, and one immediate (Red) patient. There were 32 patients who received on-site care by DMAT. Two patients were transferred from a local hospital to Wonju Severance Christian Hospital for hyperbaric oxygen therapy. Conclusion: Twenty-nine victims were found in the sports complex building, and there were 31 mildly to moderately injured patients in this fire disaster. The main cause of death was thought to be smoke suffocation. Although DMAT was activated relatively quickly, it was not able to provide effective activity due to the late rescue and difficulty with fire suppression.

  • Although the importance of resilience is emerging around the world, the single definition of resilience related to natural disasters is not clear. The reason for this is that there is no specific definition of how the definition of resilience relates to similar terms such as vulnerability, recovery, adaptability, and sustainability. In addition, it is because each country and region have different geographic and geological characteristics, and each measurement index is different, just as typhoons, droughts, and earthquakes have different types of disasters. Therefore, in this study, the definition of resilience is reflected in the spatial characteristics of this study as the ability to recover from'complex disasters (concentrated heavy rain, landslides, earth and stone flows) occurring on local roads or on local roads adjacent to people or facilities. Defined. And it was divided into DRR: Disaster Resilience focusing on the Road. In addition, domestic and foreign literature surveys were conducted to derive road-centered disaster resilience factors, and a hierarchical structure was established and AHP survey was conducted to establish a DRR evaluation system. As a result of the analysis of the AHP survey, the weight of direct road disaster influencing factors (drainage facilities, protection facilities, etc.) located inside local roads was 0.742, and the weight of indirect road disaster influencing factors (population, property, etc.) located near local roads. Was found to be 0.258, indicating that the direct impact factor of road disaster was relatively higher than that of the indirect impact factor.

  • Along with high-rise buildings, complex buildings used by many unspecified people, such as various buildings and underground-linked buildings, are increasing. In particular, high-rise buildings are accompanied by a number of casualties and a lot of property damage in the event of a disaster, so reinforced integrated disaster management is necessary. The High-Rise Disaster Management Act stipulates that a general disaster manager is appointed and requires stricter safety management tasks than other buildings. Therefore, this study aims to analyze and present item factors for a preliminary survey of job satisfaction of general disaster managers through literature research and expert verification.

  • In this study, a complex simulation prototype was developed for rapid and accurate prediction of chemical dispersion range in order to reduce human casualties caused by chemical accidents. Complex simulation considered the leakage momentum during the near-field dispersion to take into account the leakage characteristics of the chemical. In the far-distance dispersion process, the wind distribution of the existing model, which was presented uniformly, was improved using weather and topographical information around the accident site, to realize a wind field similar to the actual one. Finally, the damage range was more precise than the existing model in line with the improved near- and far-distance dispersion process. Based on the results of damage range prediction of the complex simulation, it is expected that it will be highly utilized as a system to support policy decision-making such as evacuation and return of residents after a chemical accident.

  • Climate change, rapid urbanization, and population concentration have led to a higher frequency and magnitude of disasters in the world. Recently, the occurrence of large-scale complex disasters, which are caused by a combination of natural disasters, man-made disasters, and social disasters, is increasing. In Korea, there are many case studies of damage prediction and response technology development for individual natural disasters, such as earthquakes, floods, and typhoons. On the other hand, the system basis for the efficient response and management of large-scale complex disasters is insufficient. Therefore, this study examined the representative cases of natural, social disasters, and related cases of domestic disaster response management systems. In addition, this paper proposes ways to improve the legal system for complex disaster management policies and establish a cooperation system between the ministries for an efficient response.
