Place names in North Korea has been regarded as an effective instrument of revolution since division of territory(1945) and as typical case which politcal ideology affected the place names. Especially in North Korea, self-reliance ideology(Juche Idea) and idolization of Kim Il Sung influenced the place names. With local administrative district reform in 1952, names of district and village were changed on national scale. National survey of place names were proceeded in 1964~1966 with direct support of Kim, Ilsung. After this survey, North Korea made alteration of place names in terms of idolization of Kim Il Sung family as well as socialist revolution. Encyclopedia of place names were widely published. Almost linguist were forced to produce writing and papers for the praise of the legitimacy of new place names. But it should be attended that research trend are slowly changed since 2000s. Research for idolization of Kim Il Sung has become a little importance.

This study aims to reveal the multilayered nature of the formal aspects of communal house architecture in North Korea. It is said that Kim Jong Il, who emerged as a successor after the mid-1970s, brought about a change in the architecture, leading the construction of a sculptural communal house on Gwangbok Street in 1989, and wrote The art of architecture (1992), which theorized architecture as an object of art. Therefore, it is widely perceived that the communal house was transformed from a simple form of living function to an artistic architecture with the rise of Kim Jong Il. This study, however, argues that this change was the result of an internal evolution in North Korean architecture, rather than a simple change in the position of an individual in power. It seeks to move away from the dichotomy that divides the communal house into two periods: the "KimIl-sung period," in which the communal house was laid out in a simple form to provide mass supply and a socialist lifestyle, and the "Kim Jong-il period," in which the communal house took on an artistic form, such as the Gwangbok Street communal house, in the early years of reconstruction. In the 1950s and 1960s, before KimJong-il's arrival, the communal house form was not simply a flat arrangement, but a three-dimensional and sculptural consideration of the effect on the cityscape.

In order to direct the form of the immune response in an antigen-specific manner, we constructed a fusion protein (OVA/IL12) that contained the T cell-dependent antigen, ovalbumin (OVA), covalently linked to murine interleukin-12 (IL-12). The OVA/IL12 protein was produced in a baculovirus expression system and was purified by anti-OVA immunoaffinity chromatography. The purified OVA/ILI2 protein displayed potent IL-12 bioactivity in an IL-12 proliferation assay. BALB/c mice immunized with the OVA/IL12 protein produced increased quantities of anti-OVA IgG2a antibody compared with mice immunized with recombinant OVA alone. Lymph node cells from the immunized mice with the OVA/IL12 protein produced large amounts of IFN-,Y when restimulated in vitro with OVA, while those from mice immunized with the OVA protein produced little or no IFN-.gamma.. In contrast, immunization with a mixture of OVA and free recombinant IL-12 also induced IFN-.gamma. production, which was not OVA-specific. These studies indicate that the OVA/IL12 fusion protein can induce OVA-specific, Th1-dominated immune responses, and that the covalent linkage of OVA and IL-12 confines the effect of IL-12 to OVA-specific cells.

Effects of power ratio on the electrical and optical properties of Au based Ga-, B- codoped ZnO(GZOB) thin films were investigated. GZOB thin films on Au based PC flexible substrate were deposited at various power in the range from 50 to 125 W by DC magnetron sputtering. Au layer was fabricated to achieve good electrical conductivity. The presence of additional boron impurity leads to improve structural defects. Thus, the c-axis orientation along (002) plane was enhanced with the increasing of power ratio and the surface morphology of the films showed a homogeneous and nano-sized microstructure. GZOB films grown at 125W were investigated a low resistivity value of $1{\times}10^{-3}{\Omega}cm$ and a visible transmission of 80% with a thickness of 300nm.

The antitumor effects of the 2E4 and anti--Tac, monoclonal antibodies directed to Il-2 receptor (IL-2R) conjugated with .alpha.-particle emitting radionuclide bismuth-212., were compared. The $^{212}Bi-2E4$ demonstratedspecific cytotocicity to EL4J3, 4, a I$L-2R^+$ cell line, than to EL4J, a $IL-2R^-$ cell line in thymidine incorporation assy. TEX>$^{212}Bi-2E4$ exerted the maximal antitumor effect in that % T/C in C57BL/6 mice implanted with EL4J3.4 ascitic tumor was 331% at the concentration of $50{\;}{\mu}Ci$, while that of $^{212}Bi-anti-Tac$ was 258% at $100{\;}{\mu}Ci$.

Instrument transformers provide the reproduction of the primary current or voltage to the measuring and protecting devices. The errors of an iron-cored transformer are caused by the difference between the primary and secondary currents due to the hysteresis characteristics of the iron-core. An error compensating algorithm for instrument transformer can improve the accuracy of conventional current and voltage transformers. This paper describes the performances of the electronic current and voltage transformers mounted an error compensating algorithm. The test results of the electronic transformers in Korea Electrotechnology Research Institute(KERI) are presented.

Pharmacological inhibition of interleukin-12 (IL-12) production may be a therapeutic strategy for preventing the development and progression of disease in experimental models of autoimmunity. In this study, the effects of myricetin, a naturally occurring flavonoid present in fruits, vegetables and medicinal herbs, on the production of IL-12 were investigated in mouse macrophages stimulated with lipopolysaccharide (LPS). Myricetin significantly inhibited the LPS­induced IL-12 production from both primary macrophages and the RAW264.7 monocytic cell-line in a dose-dependent manner. The effect of myricetin on IL-12 gene promoter activation was analyzed by transfecting RAW264.7 cells with IL-12 gene promoter/luciferase constructs. The repressive effect was mapped to a region in the IL-12 gene promoter containing a binding site for NF-${\kappa}B$. Furthermore, activation of macrophages by LPS resulted in markedly enhanced binding activity to the NF-${\kappa}B$ site, which significantly decreased upon addition of myricetin, indicating that myricetin inhibited IL-12 production in LPS-activated macrophages via the down­regulation of NF-KB binding activity.

The purpose of this research is to reevaluate the success factors and significance of the battle through the analysis of the only successful Chuncheon district battle during the defense combat in the early part of the Korean War on June 25, 1950. The research results are the matters that are analyzed from the viewpoint of the armed forces of the Republic of Korea, focusing intensively on the successful aspect of the early defense combat against North Korean army's surprise invasion of the South and on the battle that thwarted the North Korean army's intensive surprise attack intention. This research attempts to reanalyze the Chuncheon District Battle in connection with the Kim Il-sung's strategic course of action in consideration of the operation plan of North Korean invasion of the South. In other words, it is to reanalyze the enemy tactics in connection with North Korean army's plan of invasion of the South. The fact that the 6th Division of the armed forces of the Republic of Korea destroyed the North Korean army's operations plans that were in accordance with Kim Il-sung's strategic plans has more significance than a simple tactical success. The Chuncheon District Battle should be reevaluated as the "decisive battle" which went beyond a successful early defense combat in a Chuncheon region, and which fundamentally defeated North Korean army's war plan itself by thwarting the Kim Il-sung's strategic plan.
