In July and October of this year, the government announced the 'Green new deal plan within the Korean new deal policy' and 'Strategies for proliferation of future vehicles and market preoccupation'. And, in response to changes in the global climate agreement, it has decided to expand green mobility such as electric vehicles and hydrogen electric vehicles with the aim of a "net-zero" society. Accordingly, the goal is to build 310 hydrogen refueling stations along with the supply of 60,000 hydrogen vehicles in 2022, and the hydrogen infrastructure is being expanded. however, it is difficult to secure hydrogen infrastructure due to expensive construction costs and difficulty the selection of a site. In Korea, it is possible to build a mobile hydrogen station according to the safety standards covering special case of the Ministry of Industry. Since the mobile hydrogen station can be charged while moving between authorized place, it has the advantage of being able to meet a large number of demands with only one hydrogen refueling station, so it is proposed as a model suitable for the early market of hydrogen infrastructure. This study demonstrates the establishment of a hydrogen refueling station by deriving a virtual accident scenario for leakage and catastrupture for each facility for the risk factors in a mobile hydrogen station, and performing a quantitative risk assessment through the derived scenario. Through the virtual accident scenario, direction of demonstration and implications for the construction of a mobile hydrogen refueling station were derived.

Background: Some of the introduced alien species introduced settle, multiply, and spread to become invasive alien species (IAS) that threaten biodiversity. To prevent this, Korea and other countries legally designate and manage alien species that pose a risk to the environment. Moreover, 2160 alien species have been introduced in South Korea, of which 1826 animals and 334 plants are designated. The inflow of IAS can have negative effects such as ecosystem disturbance, habitat destruction, economic damage, and health damage to humans. To prevent damage caused by the inflow of IAS in advance, species that could potentially pose a risk to the environment if introduced in South Korea were designated as alert alien species (AAS). Results: The designation criteria were in accordance with the "Act on the Conservation and Use of Biological Diversity" and the "Regulations on the Ecological Risk Assessment of AAS and IAS" by the National Institute of Ecology. The analysis result of risk and damage cases indicated that mammals affect predation, competition, human economic activity, virus infection, and parasite infection. Birds have been demonstrated to affect predation, competition, human economic activity, and health. It was indicated that plants intrude on the ecosystem by competing with native species with their high-population density and capacity to multiply and cause allergic inducement. Interestingly, 300 species, including 25 mammals, 7 birds, 84 fishes, 28 amphibians, 22 reptiles, 1 insect, 32 spiders, 1 mollusk, 1 arthropod, and 99 plants, are included in the list of AAS. Conclusions: AAS designation plays a role in preventing the reduction of biodiversity by IAS in South Korea and preserving native species. Moreover, it is determined to provide considerable economic benefits by preventing socio-economic losses and ecological damage.

Numerous regulations have been introduced and a various kinds of institutional intervention have been made by government against the occupational safety and health problems. However, it was serious issue to the workers that what can be claimed by those who meet with apparently harmful and risky working conditions in their social systems. In the view point of employees, their right to be free from unacceptable risk and hazards has not been clearly defined. Therefore, workers have very limited rights to take any actions unless employer or government do their actions. It is believed that this undesirable conditions resulted from Jack of legal definition of workers' right to work in the safe and healthy environment. It has been found increased social pressure to make intervention to the industry to protect workers' health. Also, increased pressure has been kept for deregulation. This conflict lay the current situation in dilemma. The concept of the working environmental right has been developed and discussed in this study to overcome this trade-off confliction. It should be clearly separated between legal aspects and administrative and Policy area to make the regulations effective. Strong enforcement to the industry based on the law should be minimum, however, it should be practically effective in the aspect of workers' right. Administration and policy should be focused on supportive and leading activities to achieve the ultimate goal, safe and healthy working environment. It is concluded that establishment of working environmental right would satisfy workers and industry and it would result in improvement workers' environment and conditions.

There has been 10 years since The Health Promotion Act was legislated. The government began to establish a health promotion fund on the basis of Health Promotion Act in 1995, and to manage and operate the fund from 1998. It is evaluated that health promotion program have had various outcomes in many aspects. First, there has been growing awareness of the impotance of health promotion through the establishment of Health Plan 2010 and the effort to actualize the Plan. Second, the importance of securing health equity and identifying health determinants have been recognized during the planning process of Health Plan 2010. Third, the health promotion program have mainly focused on improving healthy life style of the population. As a result, desirable health behavior change of the population could be expected from the result of 2005 National Health and Nutrition Survey. Fourth, public health centers began to play a crucial role in implementing health promotion programs, and began to build infrastructure for health promotion programs. Fifth, the outcomes of health promotion programs by public health centers and private health organizations have been increasing. Finally, training for health promotion personnel and their participation in the program could be the foundation for the higher level of outcome achievement from the health promotion programs. Important challenges for future health promotion would be identification of the determinants and risk factors of health in Korea, establishment of local health promotion plan, building infrastructure for health promotion, creation of specific action model by public health center, development of diverse health promotion programs and health promotion program for the elderly, conducting research for evidence concerning major factors reducing the need for health care through prevention disease activities, and establishment of evaluation and feed back system for health promotion programs.
