During the decades after the Fukushima Daiichi Nuclear Power Station (FDNPS) accident, ambient dose rates have markedly decreased when compared to those at the early state of the accident. Government projects have been continuously conducted by surveying the ambient dose rate and radiocesium distributions. Airborne surveys using crewed helicopters and unmanned aerial vehicles (UAVs) are the best methods for obtaining an overall picture of the distribution. However, ground-based surveys are required for accurate measurements near the population. The differences between these methods include the knowledge of the post depositional behavior of radionuclides in land use. The survey results form the basis for policy decisions such as lifting evacuation zones, decontamination, and other countermeasures. These surveys contain crucial findings regarding post-accident responses. This paper reviews the survey methods of government projects and current situation around the FDNPS. The visualization methods and databases of ambient dose rates are also reviewed to provide information to the population.

Construction accident rates are reflected in the pre-qualification of public construction projects in order to prevent accidents and facilitate the safety management of construction companies. However, the construction industry is still experiencing an increase in accident rates. Hence, there is a need to strengthen existing safety evaluation systems and requirements in public construction tendering. The objective of this study was to acquire and provide basic data for benchmarking to select tenderers in domestic public construction projects. In Singapore and Japan, safety evaluation systems and requirements are applied based on various aspects in order to screen tenderers. These evaluation systems include safety regulations and institutional requirements, as well as safety performance and safety management plans of respective construction projects. This study recommends that korean public construction projects also apply similar safety evaluation systems which include comprehensive safety criteria in order to decrease accident rates in the industry.

Vehicle Inspection System is to examine the condition of vehicle regularly at the national level to protect lives and properties of the people from traffic accidents due to vehicle's fault. However, the vehicle inspection method, criteria, period and effectiveness have become a controversial issue, because of examining safety management of vehicle by drivers regardless of regular vehicle inspection. Therefore, the aim of this study is to investigate vehicle inspection timeliness and risk level of inspection items through basic statistical survey and portfolio analysis. The results of the research through practical analysis are: (1) The inspection failure rates between 3 and 6 model year tend to increase. (2) The failure of inspection items for safety highly impacts on traffic accident rate in terms of accident risks. (3) According to the result of portfolio analysis, faulty items located 1st quadrant are riding device, driveline system, controlling device, steering actuator, and fuel system.

Korea reached an aging society in 2000, and it is progressed quickly now. Government forecasts that the number of aged people over 65 years old will increase from 7.2%(2000) to above 14.3% among total population in 2018. Workers over fifty years old are increasing in construction field every year. These aged workers are exposed to various construction accidents, and also their accident rate is very high because of physical and psychological changes by aging. Specially, a disaster of aged workers more than 50 years old is fronted at the serious situation in the construction industry which has variable working environment. Thus, the purpose of this study is to suggest the precaution by analysing disaster characteristics of aged construction workers. Also, this study aims to present a basic counter-plan according to important safety management list which is abstracted from the work, aged construction workers' accident rate is high.

Various safety measures have been established and implemented in order to reduce construction accidents. However, statistics data on at construction sites still show higher accident and mortality rates than other industries. As a result of investigating the causes of accidents occurring in the construction industry, most accidents resulted from the failure of the system. Therefore, the existing safety management system of the construction site is monitored so that it operates properly in the field, and it is an important factor to actively participate in construction work. In order to overcome this, the government emphasized on-site inspections and planning and implementation confirmation by public institutes to ensure the effectiveness of the safety management system through amendment of the Construction Technology Promotion Act, but the orderer' safety capability and manpower are insufficient at present. Therefore, in this study, the safety management system, such as design for safety, safety management plan, safety check, safety management cost, etc. specified in the Construction Technology Promotion Act, is regularly checked and confirmed to improve the effectiveness of the safety management system as well as to improve the safety management system of the construction site by deriving measures to strengthen the public function of the government.

According to the statistics from the Ministry of labor, 70~80 people died by work-related electric shock accidents in the workplace and this number is about 10~20 times higher than those of the foreign countries such as Japan and the United Kingdom in frequencies and rates per 100,000. The electrocution deaths had decreased from several hundred in 1990s to 67 in 2002, since then there has been little change over the last 5 years. To reduce this number of the electrocution death, it is necessary to analyze the sources of the accidents and to implement the suitable measures for preventing the similar accidents from occurring. But there is not any consensus standard method or procedures for accident investigation yet. And the results solely depend on the ability of the investigator. Because of the demand of eliminating technical barrier for free trading, the IEC 60364 is adopted as a regulation for low voltage electrical installations in Korea. The facilities designed and constructed by IEC 60364 are increasing. The facilities by IEC 60364 have different features in comparison with the facilities by Korea eletro technical regulation, and these features combined with parameters of electric shock accident can greatly affect the consequences of the electric accidents. The accident analysis program for electric shock injuries in Terra Neutral(TN) and Terra Terra(TT) system was developed in this paper, which was based on KOSHA Electric Shock Analysis Program(ESAP).

EMSS is the organic system offering quick and efficient transfer and treatment for those who need an emergency service. For EMS aviation operation is the important transportation for the common benefits. There are several types of aviation operation. Among the different types of the operations, helicopter operation is very common because it is free from any locations. Notwithstanding the benefit, various types of EMS helicopter accidents and incidents are occurred because of its poor operation condition. In South Korea, even though so much effort was put to decrease the accidents rates, there are still many accidents happening by fire helicopters and the forest service helicopters. Therefore, in order to regularize the EMSH operation, measures for the aviation safety have to be prepared. This research is, related to the EMSH, focused on the suggestion of safety measure for the EMSH in Korea based on the accidents analysis in various countries.

This paper proposes a combined plastic and creep constitutive model of A533B1 pressure vessel steel to simulate progressive deformation of nuclear pressure vessels under severe accident conditions. To develop the model, recent tensile test data covering a wide range of temperatures (from RT to 1,100 ℃) and strain rates (from 0.001%/s to 1.0%/s) was used. Comparison with experimental data confirms that the proposed combined plastic and creep model can well reflect effects of temperature and strain rate on tensile behaviour up to failure. In the companion paper (Part II), the proposed model will be used to simulate OECD lower head failure (OLHF) test data.
