[en] Progress of molecular biology, genetic engineering, and polymer chemistry provide various tools to target molecules and cells in vivo. In this paper, recent achievements in targeting receptors for hepatocyte or inflammatory cells and in trafficking bacterial, immune, and stem cells using molecular nuclear imaging techniques are introduced

[en] The preliminary study was performed to optimize fast neutron radiography system. The analysis was conducted about the performances and characteristics of each components; mirror and lens, scintillator and CCD camera. It was estimated that the efficiency of scintillator would be important factor to determine quality of image

[en] An arylpiperazine, WAY100635, has been found as a highly selective ligand for imaging 5-HT_1A receptor among other serotonergic receptors. We have established an efficient method for the synthesis of the arylpiperazine derivatives in which the acylation of 2-aminopyridine, the coupling reaction of the acyl compound with piperazines, and reduction of the arylpiperazines were performed under microwave irradiation (300 W) to afford the corresponding target compounds in quantitative yields. The synthesis time of the acylation, the coupling reaction and the reduction was remarkably reduced compared with that of the conventional method

[en] Cold neutron spectroscopy is a unique tool in condensed matter physics that provides direct access to the many body response functions at low energies. In this paper, we describe modern instrumentation for cold neutron triple-axis spectroscopy and present an example of research performed using the technique

[en] In this paper a brief summary of the monitoring system of In-Pile Section(IPS) is described. To meet the user requirements on the test fuel and irradiation conditions, various instruments are installed on the test fuel pin itself and the appropriate locations in IPS. The requirements and descriptions for instruments, gas supply system, and the data acquisition system to sample and record parameters are described

[en] The major elements which must be considered in the design of a cold neutron source are identified, and possible solutions are presented. Alternative solutions are illustrated by examples from existing and planned cold neutron sources

[en] Thanks to progress in neutron optics and polarization techniques neutron Three-Axis Spectrometers (TAS) became an efficient tool to collect information on inelastic response over Q, ω ranges comparable in size to a single Brillouin zone. In the forthcoming decade we do expect a strong complementarity rather than competition between the Time-Of-Flight (TOF) instruments for single crystal spectroscopy at the existing (ISIS) as well as at the newly built (SNS, J-PARK) pulsed sources and the reactor-based TAS's

[en] Acovienient method for piperidines containing ο-carborane moiety is described. 5a, 5b, 5d, and 5e were found accumulate in B-16 melanoma cells with a significantly high level, although with low cytotoxicity

[en] This proceedings contains articles of international symposium on research reactor and neutron. It was held on April 11-13, 2005 in Taejon, Korea. This proceedings is comprised of ten sessions. The subject titles of session are as follows: research reactor, radioisotopes, irradiation tests, activation analysis, neutron radiography, cold neutron source and guides, neutron diffraction, inelastic neutron scattering, small angle neutron scattering and neutron reflectometry, university reactors (Yi, J. H.)

[en] Recently some defective fuel rods and intact fuel rods were transported from the storage pool in the nuclear power plant site to the PIE facility in KAERI. The non-destructive examination, destructive examination, and chemical examination were carried out in the hot cells. Then the oxide layer thickness of clad inner surface and outer surface were examined. In this study, the oxide state and hydride structure of the intact fuel rod and the defective fuel rod are evaluated with the results of the PIE
