  • Shantou Bay Bridge is the first long-span suspension bridge in China. Because of its location near the Shantou Seaport and its exposure to high typhoon winds, wind-resistant studies are necessary to be made. In this paper, critical flutter wind speeds and buffeting responses of this bridge at its operation and main construction stages are investigated. The Buffeting Response Spectrum method is first briefly presented. Then the sectional model test is carried out to directly obtain the critical flutter wind speed and to identify the flutter derivatives, which are adopted for the later analysis of the buffeting responses using the Buffeting Response Spectrum method. Finally the aeroelastic full bridge model is tested to further investigate the dynamic effects of the bridge. The results from the tests and the computations indicate that the flutter and buffeting behaviors of the Shantou Bay Bridge are satisfied.

  • Storm and flood damage management systems in national disaster management system(NDMS) were organized into three operation systems. They are prevention, preparation, response, and recovery systems. Disaster resources in each system must be promptly and exactly applied to minimize casualties and loss of properties. However, the disaster resources in current management system can not be immediately used in calamity situation due to the lack of efficiency in statistical data. Therefore, it is necessary to classify the emergency restoration equipment for efficient management and mobilization of disaster resources in disaster situation. In this study, field survey was executed to appropriately classify the emergency restoration equipment. Problems and reformation points of the disaster resources system were also presented to improve the classification technique and to construct the data base.

  • In the event of a large-scale disaster such as an earthquake, typhoon, landslide, and building collapse, the disaster situation awareness and timely disaster information sharing play a key role in the disaster response and decision-making stages for disaster management, such as disaster site control and evacuation of residents. In this paper, an exited field investigation system of NDMI (National Disaster Management Research Institute) was enhanced with an LTE-VPN- based wireless communication system to provide an effective on-site response in an urgent disaster situation and share observation data or analysis information acquired at the disaster fields in real-time. The required performance of wireless communication for the disaster field investigation system was then analyzed and evaluated. The experimental result for field data transmission performance of an advanced wireless communication investigation system showed that the UDP transmission performance of at least 4.1Mbps is required to ensure a seamless video conference system between disaster sites. In addition, a wireless communication bandwidth of approximately 10 Mbps should be guaranteed to smoothly share the communication and field data between the survey equipment currently mounted on the survey vehicle.

  • Objective : In October 2016, the most powerful earthquake, magnitude 5.1 and 5.8 struck the city of Gyeongju in Korea. Although it did not take a toll, this implicates potential disaster in the future. Taking this earthquake, this paper considers the healthcare system responding to disaster in non-government organization and other countries, and investigates the roles of occupational therapist in disaster management. Methods : This paper reviews literature related to healthcare system and roles of occupational therapist in disaster response. Results : Humanitarian recovery mission of Red Cross impacted and facilitated the recovery of vulnerable population including children, elderly and people with disabilities in disaster response. It was also emphasized by occurring large population with disabilities after disasters so that the concept of rehabilitation and occupational therapist's role was required. Occupational therapy practitioners play an important role in the stage of disaster preparedness, response and recovery and their target population is children, elderly and people with disabilities. Conclusion : The most of NGO and counties take the concept of rehabilitation into healthcare system responding to disaster. However, the system in Korea stays in emergency level. It is important to take the humanitarian recovery and rehabilitation concept to disaster relief. the survivors would be able to return to their normalcy and health life.
