Many thermal-hydraulic tests have been conducted at the Korea Atomic Energy Research Institute for verification of the SMART (System-integrated Modular Advanced ReacTor) design, the standard design approval of which was issued by the Korean regulatory body. In this paper, the contributions of these tests to the standard design approval of SMART are discussed. First, an integral effect test facility named VISTA-ITL (Experimental Verification by Integral Simulation of Transients and Accidents-Integral Test Loop) has been utilized to assess the TASS/SMR-S (Transient and Set-point Simulation/Small and Medium) safety analysis code and confirm its conservatism, to support standard design approval, and to construct a database for the SMART design optimization. In addition, many separate effect tests have been performed. The reactor internal flow test has been conducted using the SCOP (SMART COre flow distribution and Pressure drop test) facility to evaluate the reactor internal flow and pressure distributions. An ECC (Emergency Core Coolant) performance test has been carried out using the SWAT (SMART ECC Water Asymmetric Two-phase choking test) facility to evaluate the safety injection performance and to validate the thermal-hydraulic model used in the safety analysis code. The Freon CHF (Critical Heat Flux) test has been performed using the FTHEL (Freon Thermal Hydraulic Experimental Loop) facility to construct a database from the $5{\times}5$ rod bundle Freon CHF tests and to evaluate the DNBR (Departure from Nucleate Boiling Ratio) model in the safety analysis and core design codes. These test results were used for standard design approval of SMART to verify its design bases, design tools, and analysis methodology.

In this paper, we analyze the paradigm shift of radio policy with the development of radio technology. In particular, we propose the definition of spectrum sharing, which is now omitted in the Korean radio law, and analyze the category of spectrum sharing depending on the licensing regime. Also we propose to extend the spectrum usage right, which defines only exclusive usage rights by spectrum auction in the Korean radio law, to all the stations which use radio spectrum and to restructure the Korean radio law.

The purposes of this study which was conducted by applying three projection formulae to the data from admission quota for paramedic of the Ministry of Education & Human Resources Development the number of ambulances the number of emergency medical centers of the Ministry of Health & Welfare and rate of successful candidates of annual report of the National Health Personnel Licensing Examination Board were to find out demand and supply of paramedic from 2002 to 2045 and to expand scope of practice of paramedic in Korea. The conclusions from this study were summarized as follows; (1) The simple formulae derived from the projection formula of the Economic Planning Board were applied under the present Emergency Medical Services Act including qualifying over 3-years experienced EMT-Basic for paramedic examinee, stationing paramedic or EMT-Basic or physician or nurse per ambulance, stationing paramedic or EMT-Basic per emergency medical center and under the amended Emergency Medical Services Act including qualifying only paramedic graduate for paramedic examinee, stationing 4.5 paramedics per ambulance, stationing 10 to 2 paramedics per emergency medical center. (2) It was estimated that on the American basis of 5.6 EMTs per 10,000 in 1996, the number of paramedics under the present act will reach the basis before 2020, the number of paramedics under the amended act will reach the basis about 2040. (3) It was estimated that on the basis of 22,000 paramedics demanded from the number of ambulances, the number of emergency medical centers in 2001, the number of paramedics under the present act will reach the basis before 2015, the number of paramedics under the amended act will reach the basis about 2030. (4) There was relationship between requirements for emergency medical centers scope of practice of paramedic in the act and demand-supply of paramedic, this necessitates surveys, studies, amendment of the act, legalization for expanded scope of practice of paramedic including EMD, instructor, teacher of safety. (5) This study which includes only expanded scope of practice of paramedic and projection for paramedic in the act needs complementary studies such as decision-making process in health manpower policy and so on.

As the management plan for domestic spent nuclear fuel is delayed, the storage of the operating nuclear power plant is approaching saturation, and the Kori 1 Unit that has reached its end of operation life is preparing for the dismantling plan. The first stage of dismantling is the transfer of spent nuclear fuel stored in storage at plants. The spent fuel management process leads to temporary storage, interim storage, reprocessing and permanent disposal. In this paper, the technical issues to be considered when transporting spent fuel in this process are summarized. The spent fuels are treated as high-level radioactive waste and strictly managed according to international regulations. A series of integrity tests are performed to demonstrate that spent fuel can be safely stored for decades in a dry environment before being transferred to an intermediate storage facility. The safety of spent fuel transport container must be demonstrated under normal transport conditions and virtual accident conditions. IAEA international standards are commonly applied to the design of transport containers, licensing regulations and transport regulations worldwide. In addition, each country operates a physical protection system to reduce and respond to the threat of radioactive terrorism.

In the print world libraries have served as the archival repository for journals that they owned. In the age of digital information, however, with the licensing of electronic journals libraries purchase access to journal contents rather than paying for ownership. Libraries note the potential benefits of electronic journals, but also quake at the thought of inaccessible electronic journal contents caused by lack of preservation, changing technology, or publisher requirements. It is real that libraries have not yet stepped in to create archives of the electronic journals they are purchasing. In the digital environments, publishers, libraries, and other information providers are not the independent units that we used to be. It will take us all working together to solve the problem of preserving access to electronic journals. Thus, it is reasonable that a national library would be charge of making a comprehensive archiving policy on electronic journals, and that cooperative agreements of local libraries can help divide responsibility for different subject areas or materials.

Regulation for the testing and operation of automated vehicles on public roadways has been recently developed all over the world. For example, the licensing standards and the evaluation technology for automated vehicles have been proposed in California, Nevada and EU. But specific safety evaluation scenarios for automated vehicles have not been proposed yet. This paper presents safety evaluation scenarios for extraordinary service permission of automated vehicles on highways. A total of seven scenarios are selected in consideration of safety priority and real traffic situation. Six scenarios are relevant with lane keeping and one scenario is relevant with lane change. All scenarios are developed based on existing ADAS evaluation scenarios and repeated simulation of automated vehicle algorithm. Safety evaluation factors as well as scenarios are developed. The safety factors are based on existing ADAS ISO requirements, ADAS safety factors and current traffic regulations. For the scenarios, a hunter vehicle is needed in addition to automated vehicle evaluated. The hunter vehicle performs multiple roles like preceding vehicle, cut-in vehicle and so on. The hunter vehicle is also automated vehicle equipped with high performance GPS, radar and Lidar. All the scenarios can be implemented by driving a lap on a KATRI ITS test track. These scenarios and safety evaluation factors are investigated via both a computer simulation and an experimental vehicle test on the test track. The experimental vehicle test was conducted with two automated vehicles, which are the evaluated vehicle and the hunter vehicle.

The 14 MeV neutron generator facility is being developed by the Institute for Plasma Research India to conduct the lab scale experiments related to Indian breeding blanket system for ITER and DEMO. It will also be utilized for material testing, shielding experiments and development of fusion diagnostics. Occupational radiation exposure control is necessary for the all kind of nuclear facilities to get the operational licensing from governing authorities and nuclear regulatory bodies. In the same way, the radiation exposure for the 14 MeV neutron generator facility at the occupational worker area and accessible zones for general workers should be under the permissible limit of AERB India. The generator is designed for the yield of 10¹² n/s. The shielding assessment has been made to estimate the radiation dose during the operational time of the neutron generator. The facility has many utilities and constraints like ventilation ducts, accessible doors, accessibility of neutron generator components and to conduct the experiments which make the shielding assessment challenging to provide proper safety for occupational workers and the general public. The neutron and gamma dose rates have been estimated using the MCNP radiation transport code and ENDF -VII nuclear data libraries. The ICRP-74 fluence to dose conversion coefficients has been used for the assessment. The annual radiation exposure has been assessed by considering 500 h per year operational time. The provision of local shield near to neutron generator has been also evaluated to reduce the annual radiation doses. The comprehensive results of radiation shielding capability of neutron generator building and local shield design have been presented in the paper along with detailed maps of radiation field.

The major object of the Space Exploitation Act lies in defining and governing the object and definition which is distinct from the ones regulated by the Aerospace Industry Act. The concept of "space exploitation" defined in the Act is defined for that purpose. The space exploitation is defined as a comprehensive concept including the research and development of the space technology which is only enabled through the actual utilization and space exploration activities. Based upon such conceptualization, any problem related to the present legal system might be put up with, especially space exploitation being differentiated from the space industry. On the other hand, the Act is to make the international obligations derived from the international treaties be fulfilled through the minimal regulation with respect to the space activities such as space object registration procedure, the licensing regime of launching activities from the korean territory, etc.
