With the rapid increases of the amount of data and computing, the parallelization of the computing algorithm becomes necessary more than ever. However the parallelization had been conducted mostly in a super-computer until the rod 1990s, it was not for the general users due to the high price, the complexity of usage, and etc. A new concept for the parallel processing has been emerged in the form of K-clustering form the late 1990s, it becomes an excellent alternative for the applications need high computer power with a relative low cost although the installation and the usage are still difficult to the general users. The mapping algorithms (cut, join, resizing, warping, conversion from raster to vector and vice versa, etc) in GIS are well suited for the parallelization due to the characteristics of the data structure. If those algorithms are manipulated using PC-clustering, the result will be satisfiable in terms of cost and performance since they are processed in real flu with a low cos4 In this paper the tools and the libraries for the parallel processing and PC-clustering we introduced and how those tools and libraries are applied to mapping algorithms in GIS are showed. Parallel programs are developed for the mapping algorithms and the result of the experiments shows that the performance in most algorithms increases almost linearly according to the number of node.

LBH is a transcription factor as a candidate gene for CHD associated with partial trisomy 2p syndrome. To identify potential LBH-interacting partners, a yeast two-hybrid screen using LBH as a bait was performed with a human heart cDNA library. One of the clones identified encodes ${\alpha}B$-crystallin. Co-immunoprecipitation and GST pull-down assays showed that LBH interacts with ${\alpha}B$-crystallin, which is further confirmed by mammalian two-hybrid assays. Co-localization analysis showed that in COS-7 cells, ${\alpha}B$-crystallin that is cytoplasmic alone, accumulates partialy in the nucleus when co-transfected with LBH. Transient transfection assays indicated that overexpression of LBH or ${\alpha}B$-crystallin reduced the transcriptional activities of p53 and p21, respectively, Overexpression of both ${\alpha}B$-crystallin and LBH together resulted in a stronger repression of the transcriptional activities of p21 and p53. These results showed that the interaction of LBH and ${\alpha}B$-crystallin may inhibit synergistically the transcriptional regulation of p53 and p21.

The transfection efficiency of plasmid DNA was inspected using multi-cationic polymer, 5, 10, 25 and 50KD polyethylenimine (PEI). The optimal neutralization ratio of PEI/DNA complexes by agarose assay was 1.5-2.0 (nmol/nmol) without much difference in molecular weight of PEI.In vitro transfection assay, most of PEI-mediated plasmid delivery was better compared to the naked DNA. Especially, 25KD PEI at optimal condition gave higher transfection rather than the standard assay of DEAE-dextran or Lipofectin. To enhance the cell targeting delivery, the liposome formulations were introduced using phospholipids. As a result, PC/PE liposomes increased 2-2.5 times of the transfection efficiency of PEI single or PC/PE single delivery, but not the case of 25KD PEI. Moreover, the DOTAP/PE-introduced PEI delivery reduced the transfection of DOTAP/PE single delivery. All these results proved that the PEI can be used not only good transfectants and but also good DNA condensing agents in neutral/anionic liposome for cell targeting delivery.

The Electronic compass made as a pilot model in this research is comprised of a three axis magnetic sensor, an accustar clinometer, and a fiber optic gyro sensor. The results confirming the output character, performance, and the accuracy of the deviation corrects of each sensor are as follows: 1) As for the output character of the three axis magnetic sensor, the magnetic field showed a cosine curve on the X axis, a - sine curve on the Y axis, and constant figures on the Z sensor. The horizontal component H and the vertical component V of the terrestrial magnetism calculated from the output voltage were 33.2${\mu}$T and 23.95${\mu}$T respectively. 2) When the fiber optic gyro sensor is fixed on the electromotive rotation transformation and has made a clockwise rotation with the speed of 10/sec, 20/sec, and 30/sec, the relationship between the output and the rotation angle of the fiber optic gyro sensor showed proportionally constant values. 3) When the magnetic field was induced with a magnet, the deviation before the correction was significant at a high of 25. However, the deviation after the correction using Poisson correction was in the 2 range, significantly lower than before the correction. It was confirmed that automatic deviation corrects are possible with the electronic compass made as a pilot model in this research.

In this study, we report the identification and characterization of a novel C2H2 zinc finger protein, ZNF552, from a human embryonic heart cDNA library. ZNF552 is composed of three exons and two introns and maps to chromosome 19q13.43. The cDNA of ZNF552 is 2.3 kb, encoding 407 amino acids with an amino-terminal KRAB domain and seven carboxyl-terminal C2H2 zinc finger motifs in the nucleus and cytoplasm. Northern blotting analysis indicated that a 2.3 kb transcript specific for ZNF552 was expressed in liver, lung, spleen, testis and kidney, especially with a higher level in the lung and testis in human adult tissues. Reporter gene assays showed that ZNF552 was a transcriptional repressor, and overexpression of ZNF552 in the COS-7 cells inhibited the transcriptional activities of AP-1 and SRE, which could be relieved through RNAi analysis. Deletion studies showed that the KRAB domain of ZNF552 may be involved in this inhibition.

In this study, a novel member of BTB-kelch proteins, named KBTBD7, was cloned from a human embryonic heart cDNA library. The cDNA of KBTBD7 is 3,008 bp long and encodes a protein product of 684 amino acids (77.2 kD). This protein is highly conserved in evolution across different species. Western blot analysis indicates that a 77 kD protein specific for KBTBD7 is wildly expressed in all embryonic tissues examined. In COS-7 cells, KBTBD7 proteins are localized to the cytoplasm. KBTBD7 is a transcription activator when fused to GAL4 DNA-binding domain. Deletion analysis indicates that the BTB domain and kelch repeat motif are main regions for transcriptional activation. Overexpression of KBTBD7 in MCF-7 cells activates the transcriptional activities of activator protein-1 (AP-1) and serum response element (SRE), which can be relieved by siRNA. These results suggest that KBTBD7 proteins may act as a new transcriptional activator in mitogen-activated protein kinase (MAPK) signaling.

The purposes of this research are firstly to define the characteristics of movement on the costume, secondly to demonstrate that fine art, expecially in relation to kinetic art, has become a good motif in modern costume de-sign, and thirdly to examin the characteristics of movement as shown in modern costume de-sign. For this study, we selected and analyzed some costume designs among those introduced in fashion magazines, which are Collections, Fashion-Preview, Fashion Show, Collezioni, and L'Officiel that have been issued since 1988. As this research is carried out only through the analysis of pictures, it is not ac-companied by a study on material itself. The result of this study is that the ex-pression of movement on modern fashion can be shown in two ways, one is the inclusive and subordinate movement expressed on the cloth-ing according to the motion of body when they are worn, and the other is the movement caused by the very designs of clothing. And the latter can be also divided in two ways, the illusionistic movement and the actual move-ment. The expression of actual movement is made through the emphasis of direction, rhythm, and dimension of the costume. And the illusionistic movement is expressed by the de-sign to which the textile pattern or reflection of light is applied so that the movement is larger than the actual movement. A sense of direction expressed on the cos-tume by the actual movement creates a light rhythm and adds interest to the costume. This reflects a part of psychology of modern men who are not accustomed to the statics. In the rapidly changing society of information our modern men seek after movement even in the statics. It is also true in the clothing and they seem to get a psychological rest through the immediated visual change as shown in fashion design. The simple and cheerful rhythm expressed by the illusionistic movement on the costume is attempted in order to overcome the static tediousness caused by simple design. These elements of movement cause the en-largement of visible range and create another enlarged shape other than the real one, so that they come to remove the dullness and monot-ony in costume design and provoke interest in costume, as if kinetic art reveals the various aspects that transcend the closed area of fine art upon the motif of 'movement'. finally, as this paper deals with the ex-pression of movement as shown in the costume design which prevailed after 1988, it is desir-able hereafter to study more about the fashion since 1950 when kinetic art began in earnest, along with the comparative study on the ex-pression of movement in our Korean designer's and foreign designer's works.

The costumes on a royal ceremony and the changes thereafter during the Korea Empire(1897-1910) have been elucidated through the review on the paintings on Queen Myong-Hun's 70th birthday celebration and the prospectus of the ceremony. Queen Myong-Hyn wore ceremonial gown in deep blue with 51 embroidered phoenix on it. The deep blue color the royal color in the Korea Empire replaced former red color. Go-jong wore violet crown and ceremonial suit in gold color. Twenty one kinds of court dance were offered during the celebration ceremony. Costumes therein appear to have an order according to the role ofdancers. most female dancers(in 17 performances not else-where specified) wore a rather common cos-tume-flower cap outer silk garent in green hand veils in 5 colors silk skirt in red) embroidered silk belt in red and shoes in green. In Sun-you-ak two female lead dancers were red hat decorated with tiger whisker deep blue outer garment wide red belt silk boots in black bow and arrows on back and a sword and a whip in hands. In Choonaang-jon a fe-male solo dancer wore a silk outer garment in yellow silk skirt in red green lorum embroidered silk belt in red wrist band of gold embroidered red silk and 5 color hand veils. In Yon-wha-dae two young girl dancers wore lotus-form crown green outer garment wide pants in red silk red silk skirt red silk belt hand veils in jade color and silk shoes in deep red. In Moo-go 4 female dancers each wore long waist coat in blue red white and warm light green in addition to the above-mentioned common costume. In Gumkee-moo 4 female dancers wore hatlike wool helmet outer garment with narrow sleeve long silk waist coat in blue combat belt in deep blue silk and dance swords in both hands. In Youk-wha-dae 6 female dancers each wore a long waist cost in red deep blue violet pale pink green and jade color. Green color of outer garment in the above-mentioned common costume of female dancers appears intersting. Although the color was shown as yellow in the screen paintings actually it was green as evidenced by the prospectus of the celeebration ceremony.

Relatively little has been studied on the AMA-1 vaccine against Plasmodium vivax and on the plasmid DNA vaccine encoding P. vivax AMA-1 (PvAMA-1). In the present study, a plasmid DNA vaccine encoding AMA-1 of the reemerging Korean P. vivax has been constructed and a preliminary study was done on its cellular immunogenicity to recipient BALB/c mice. The PvAMA-1 gene was cloned and expressed in the plasmid vector UBpcAMA-1, and a protein band of approximately 56.8 kDa was obtained from the transfected COS7 cells. BALB/c mice were immunized intramuscularly or using a gene gun 4 times with the vaccine, and the proportions of splenic T-cell subsets were examined by fluorocytometry at week 2 after the last injection. The spleen cells from intramuscularly injected mice revealed no significant changes in the proportions of CD8$^+$ T-cells and CD4$^+$ T-cells. However, in mice immunized using a gene gun, significantly higher (P<0.05) proportions of CD8$^+$ cells were observed compared to UB vector-injected control mice. The results indicated that cellular immunogenicity of the plasmid DNA vaccine encoding AMA-1 of the reemerging Korean P. vivax was weak when it was injected intramuscularly; however, a promising effect was observed using the gene gun injection technique.
