  • More than 3.4 million people use Hong Kong metro a day. It was first constructed in 1979, and extended to 9 operating lines with 168.1km length operated by Hong Kong Mass Transit Railway Corporation (MTR). In Hong Kong, airborne viruses such as avian influenza (bird's flu) and severe acute respiratory syndrome (SARS), air pollution by high-density traffics, bacteria and mold due to relatively high humidity are major concerns on air quality management. In this study, we focused on the cases for improving indoor air quality conducted by Hong Kong MTR currently. The case includes the photocatalytic coatings on knobs (or hand straps) to prevent outbreak of bird's flu and SARS, the high voltage ionizers installed at metro platform, and the periodical radon monitoring.

  • International conferences to block the spread of Avian bird flu occurred in Beijing, 2006 and others warned of the seriousness of the H5N1 strain. The meetings succeeded in generating billions of dollars from USA, EU and World Bank. Migratory birds seem to play a major role in the spread of the aggressive strain globally from Asia to Europe and Africa. Experiences of tolerance breeding of maize (Zea mays L.) for four decades against 20 biotic stresses suggest that the prime cause of the occurrence of H5N1 strain was due to the human beings' counter-efforts against nature. Excessive use of chemicals (spray and injection) in the commercial poultry farms had created high selection pressure on virus. The new strain had mutated for survival. Attempting to eliminate the virus by chemicals for 100% control is a dangerous way to control biotic stresses. This can create more aggressive strains. A solution would be to build up tolerability of the commercial animals against the virus. Improvement of poultry cage environments and respect for nature must be integrated. Potential foes must be watched.

  • The framework and application model for risk mitigation service based on network provides monitoring function of the risk event data to be inputted and analyses it for mitigation process. Furthermore, it performs the analysis of the manmade calamities such as accident, building destruction, natural calamities caused by climate change, and animal harms caused by bird flu and foot-and-mouth disease occurring in livestock and wild animals, and provides the mitigation service of it. The application model for risk mitigation is combined with network and carries out the real time acquisition and monitoring of risk events, and provides mitigation service for the risks caused by calamities and reduces economic losses.

  • Recently SARS and bird flu has been infected widely in the world; we have to care about germs and virus in indoor air environment. Especially that transmission by means of transportation is a major infection route. In this study, a private car simulated with CFD for prediction of indoor airborne microbe transport. Simulation performed with real situation in car, four occupants with a infected driver and four stage air ventilation controled by HVAC system. Result show that CFD can be visualized microbe transport other occupants and who is more exposed to airborne microbe. also it make a prediction of microbe transport in car.

  • The recent rise in SARS and bird flu infections around the world has raised the interest in studying the habits of air borne pathogens such as germs and viruses. In this study, simulations were carried out to predict the performance of UVGI air sterilizer at preventing airborne infections inside a car, based on the installation position and the removing effect of the UVGI air sterilizer. Simulation results showed that the UVGI air sterilizer was most effective when located at the rear side of the front seats. It was also showed that when the out-air mode and the UVGI air sterilizer were set to the highest capacity, the microbial safety levels were maintained in a car for 21 hours.

  • Purpose: The purpose of this study is to analyze the characteristics of animal carcasses treatment and quarantine management of infectious diseases of livestock, and to present the effectiveness of quarantine and follow-up management of livestock infectious diseases. Method: Actually, a livestock epidemic occurred and the burial site and burial management facility that treated livestock carcasses were visited on-site to analyze the management status and problems. Result: The burial method of livestock outbreaks of livestock infectious diseases and the long-term follow-up management accordingly requires a large amount of manpower and budget to be spent. For example, it can be seen that it is an inefficient quarantine system. Conclusion: It is necessary to review plans for the establishment of integrated livestock infectious animal carcasses treatment facilities at the level of metropolitan cities, districts, and municipalities with the government, where there is no fear of secondary infectious disease transmission and no follow-up management is required.

  • This study aimed to investigate the effects of social disaster risk perception levels of Koreans on government trust. To this end, differences in disaster risk perception levels based on social disaster types and the effects of social disaster risk perception levels on government trust were analyzed. In the preliminary survey, three types of social disasters with high risk levels (bird flu, fine dust, and nuclear power plants) were selected. The survey was conducted on 1,109 Korean men and women aged 20 years and older. First, the analysis results demonstrated that social disaster perception levels differed based on social disaster types. Second, the results showed that, in terms of social disasters, proactivity, personal knowledge, familiarity, severity, fear, and risk associated with chances of recovery did not affect government trust. Third, the perception of delayed social disaster risk had a positive effect on government trust. Fourth, scientific knowledge about social disasters, control capabilities, lethality, and risk perception at the onset time had a negative effect on government trust. In conclusion, the implications and limitations of this study were discussed.

  • The purpose of this study is to research the countermeasures and expected effects through the use of drones in the field of disaster prevention as a drone-based smart quarantine performance method. The environmental, market, and technological approaches to the review of the current quarantine performance task and its countermeasures are as follows. First, in terms of the environment, the effectiveness of the quarantine performance business using drone-based control is to broaden the utilization of forest, bird flu, livestock, facility areas, mosquito larvae, pests, and to simplify and provide various effective prevention systems such as AI and cholera. Second, in terms of market, the standardization of livestock and livestock quarantine laws and regulations according to the use of disinfection and quarantine missions using domestic standardized drones through the introduction of new technologies in the quarantine method, shared growth of related industries and discovery of new markets, and animal disease prevention It brings about the effect of annual budget savings. Third, the technical aspects are (1) on-site application of disinfection and prevention using multi-drone, a new form of animal disease prevention, (2) innovation in the drone industry software field, and (3) diversification of the industry with an integrated drone control / control system applicable to various markets. (4) Big data drone moving path 3D spatial information analysis precise drone traffic information ensures high flight safety, (5) Multiple drones can simultaneously auto-operate and fly, enabling low-cost, high-efficiency system deployment, (6) High precision that this was considered due to the increase in drone users by sector due to the necessity of airplane technology. This study was prepared based on literature surveys and expert opinions, and the future research field needs to prove its effectiveness based on empirical data on drone-based services. The expected effect of this study is to contribute to the active use of drones for disaster prevention work and to establish policies related to them.
