On August 25th, Korea launched KSLV-1(Naro), the first Korean launch vehicle with the payload of a small satellite. The launch itself was successful in that the first and second stage of the launch vehicle functioned properly but unfortunately the satellite was unable to be put into earth orbit due to the failure of a nose faring detachment. As the history of human space activities shows, it is recognized as a difficult task to be a launching state requiring efforts to obtain enough technical ability. But along with the technical ability, there has to be an understanding on international legal systems on space launch vehicle. It is because the launch may cause cross-border losses and because the launcher is regarded as a strategic technology resulting in international control. This paper aims to study the international status of launching state and to consider legal regimes necessary for launcher development.

The radial uniformity of neutron irradiation in silicon ingots for neutron transmutation doping (NTD) at HANARO is examined by both calculations and measurements. HANARO has two NTD holes named NTD1 and NTD2. We have been using the NTD2 hole for 5 in. NTD commercial service, and we intend to use two holes for 6 in. NTD. The objective of this study is to predict the radial uniformity of 6 in. NTD at the two holes. The radial neutron flux distributions inside single crystal and noncrystal silicon loaded at the NTD2 hole are calculated by the VENTURE code. For NTD1, the radial distributions of the reaction rate for a 6 in. NTD with a neutron screen are calculated by MCNP, and measured by gold wire activation. The results of the measurements are compared with those of the calculations. From the VENTURE calculation, it is confirmed that the neutron flux distribution in the single crystal silicon is much flatter than that in the non-crystal silicon. The non-uniformities of the measurements for radial neutron irradiation are slightly larger than those of the calculations. However, excluding local dips in the measurements, the overall trends of the distributions are similar. The radial resistivity gradient (RRG) for a 5 in. silicon ingot is estimated to be about $1.5\%$. For a 6 in. ingot, the RRG of a silicon ingot irradiated at HANARO is predicted to be about $2.1\%$. Also, from the experimental results, we expect that the RRG would not be larger than $4.4\%$.

This paper aims to examine the philosophical significance of neuroethics and its unique position within the cognitive paradigm, and to discuss major issues of neuroethics. Recent advances in neuroscience enable more direct access and intervention to human mind, which reduces the distinction between matter and mind and brings up new philosophical questions on human nature. Neuroethics takes interdisciplinary and integrative approach, in order to deal with the ethical issues related to new findings and technology of neuroscience that cannot be covered by the traditional legal and social systems. Some of the ethical issues of neuroscience overlap with the classical bioethics problems but majority of major issues are unique to neuroethics. These issues are mainly related to mind reading through the observation and decoding of brain activities and to cognitive enhancement through directly manipulating brain functions. Considering the current status and trends of Korean neuroscientific research, it is necessary to begin in-depth discussion of neuroethical issues with the collaboration among experts in related fields.

Fluorescent lamps generally involve mercury within their lamp bulbs. Thus if the lamps are disposed as they are, it might cause environmental pollution. On the other hand, as the life of the lamps depends on the degradation of the discharge performance, the fluorescent substance composing the fluorescent substance coating can be recycled by reusing them as the recycled fluorescent substance. Also, the glass material composing the glass bulbs can be reused. The range of search was limited in the open patents of USA (US), European Union (EU), Japan (JP), Korea (KR) and SCI journals from 1977 to 2011. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies. Recovery method of metals from spent fluorescent lamps is mainly the focus on the recovery of precious metals using acid treatment and, detoxification technology is related with controlling process of mercury using a filter system.
