According to revealing the DNA sequence of human and living things, it increases that a demand on a new computational processing method which utilizes DNA sequence information. In this paper we propose a classification algorithm based on negative selection of the immune system to classify DNA patterns. Negative selection is the process to determine an antigenic receptor that recognize antigens, nonself cells. The immune cells use this antigen receptor to judge whether a self or not. If one composes n group of antigenic receptor for n different patterns, they can classify into n patterns. In this paper we propose a pattern classification algorithm based on negative selection in nucleotide base level and amino acid level.

This paper estimates Adaptive Resonance Theory 1(ART1) as a vigilance parameter of pattern clustering algorithm. Inherent characteristics of the model are analyzed. In particular the vigilance parameter ${\rho}$ and its role in classification of patterns is examined. Our estimates show that the vigilance parameter as designed originally does not necessarily increase the number of categories with its value but can decrease also. This is against the claim of solving the stability-plasticity dilemma. However, we have proposed a modified vigilance parameter estimate criterion which takes into account the problem of subset and superset patterns and stably categorizes arbitrarily many input patterns in one list presentation when the vigilance parameter is closer to one.

The microwave dielectric properties of 0.6TiTe$_3$O$_{8}$-0.4MgTiO$_3$ ceramics with H$_3$BO$_3$-SnO were investigated to improve the sintering condition for the LTCC. According to the X-ray diffraction patterns, 0.6TiTe$_3$O$_{8}$-0.4MgTiO$_3$ ceramics with H$_3$BO$_3$-SnO had the columbite structure of TiTe$_3$O$_{8}$ phase and the ilmenite structure of MgTiO$_3$ phase and there were no second phase. Increasing the addition of H$_3$BO$_3$-SnO, the density and dielectric constant of the 0.6TiTe$_3$O$_{8}$-0.4MgTiO$_3$ ceramics were increased but the quality factor was decreased. The temperature coefficient of resonant frequency was shifted to the negative(-) direction with addition of H$_3$BO$_3$-SnO.EX>-SnO.

BoLA (bovine leukocyte antigens) have been known as gene complex related with bovine diseases and immunological traits. This study was conducted to find out the characteristics of BoLA-DRB3 gene related to mastitis and BL(bovine leukocyte) from 280 cattle [193 animals of Holstein cattle and 87 animals of Hanwoo]. As a result, five PCR-RFLP types (b, d, e, f and g) using HaeIII restriction enzyme, three BstYI restriction patterns (b, d and e) and eight RsaI restriction types(b, d, f, I, j, n, o and w) were identified. Moreover, we identified new d' type ($197{\rightarrow}175$/22), having one more cutting site by BstYI enzyme than d type allele and n' type ($180{\rightarrow}169$/11) having one more cutting site by RsaI enzyme than n allele was additionally identified. Next, we identified 53 SNPs in BoLA-DRB3 exon2 from 280 cattle. SNP frequency and heterozygosity of Holstein and Hanwoo were investigated in all the SNP genotype. These results might be based on research for identifying marker associated with bovine diseases.

In this study, the microwave dielectric properties of $0-6TiTe_3O_8-0.4MgTiO_3$ ceramic with $H_3BO_3$ and SnO were investigated to reduce the sintering time for the LTCC application. According to the X-ray diffraction patterns, both of $0-6TiTe_3O_8-0.4MgTiO_3$ ceramic with $H_3BO_3$ and SnO had the columbite structure of $TiTe_3O_8$ Phase, the ilmenite structure of $MgTiO_3$ phase. The density and dielectric constant of the $0-6TiTe_3O_8-0.4MgTiO_3$ ceramics with $H_3BO_3$ sintered at $830^{\circ}C$ for 1 hour were decreased but the quality factor was not changed with addition of $H_3BO_3$. Also the temperature coefficient of resonant frequency was not changed hardly. In the case of addition of SnO, the density and dielectric constant were increased but the quality factor was decreased and the temperature coefficient of resonant frequency was shifted to the negative(-) direction.

The purpose of this study was to investigate and compare the characteristics of the motifs on cultural goods in In-Sa-Dong Street, Seoul, with those in Art Street, City Hall, Kwang-ju. For this study, 607 cultural goods were collected from the two cities: 265 in Seoul and 342 in Kwang-ju. Total cultural goods were classified by accessories, decoration pieces, stationery and ceramics and were studied by repetition patterns, motifs types, representative techniques, and representative types. The results were as follows. First, for repetition patterns of motifs, there were 219 simple repetition patterns in Seoul, and 289 in Kwang-ju, and 46 compound repetition patterns in Seoul, and 53 in Kwang-ju. The ratio of simple repetition pattern was higher than that of compound repetition pattern in both cities. Second, for motif types, floral, animal, letter, and graphic motifs were used far more frequently than any other motif types. Third, for representative techniques, embroidery was far more frequently used than any other representative techniques. Metallic crafts, chil-bo and paper techniques were also favored. Fourth, for representative types, realistic types were more common than abstract types.

We have measured the space charge distribution and PD patterns simultaneously in XLPE under AC voltages by modified PEA method in order to investigate the effect of space charge on PD patterns in XLPE with air-gap. From the experimental results, we found that the dynamic space charge accumulated on the surface of XLPE due to the PD dominantly affects the PD pattern in the dielectric-barrier structure and governs the voltage across the air-gap. Moreover, the space charge formed by applying DC voltage still remained after applying AC voltage, which means that the space charge formed during DC strength test is likely to be fatal to the long-time AC insulating characteristics of HV equipments. On the other hand, the PD patterns was much influenced by the pre-formed space charge by DC application. Therefore, it is possible to detect the effects of space charge by monitoring the infinitesimal change of PD patterns before and after DC strength.

The purpose of this study was to verify the possibility of fuel rod pattern analysis in a fresh fuel assembly using the Yonsei single-photon emission computed tomography (YSECT) system. The YSECT system consisted of three main parts: four trapezoidal-shaped bismuth germanate scintillator-based 64-channel detectors, a semiconductor-based multi-channel data acquisition system, and a rotary stage. In order to assess the performance of the prototype YSECT, tomographic images were obtained for three representative fuel rod patterns in the 6 × 6 array using two representative image-reconstruction algorithms. The fuel-rod patterns were then assessed using an in-house fuel rod pattern analysis algorithm. In the experimental results, the single-directional projection images for those three fuel-rod patterns well discriminated each fuel-rod location, showing a Gaussian-peak-shaped projection for a single 10 mm-diameter fuel rod with 12.1 mm full-width at half maximum. Finally, we successfully verified the possibility of the fuel rod pattern analysis for all three patterns of fresh fuel rods with the tomographic images obtained by the rotational YSECT system.

This paper investigates the rank system of official uniforms of Qing dynasty to analyze ethnic characteristics of the official uniforms. As a research document, Qing Huidian Tu(청회전도) has been used. The official uniforms of Qing dynasty were chao-fu(조복), ji-fu(길복), chang-fu(상복), hang-fu(행복), and yu-fu(우복), which were used in different occasions. Each of the five official uniforms had distinct items. For example, chao-fu(조복) consisted of four items: chao-guan(조관), chao-fu(조복), chao-dai(조대), and chao-zhu(조주), and ji-fu(길복) consisted of four items: ji-fu-guan(길복관), long-pao(용포), ji-fu-dai(길복대), and chao-zhu(조주). Each of these items had elements that made distinction between ranks. This research shows that the important elements to make distinction between ranks were textiles, precious stones, patterns and colors, and additionally the number of Bo(보) and the types of Bo(보) were used.

This study is about researching DongEuiBoGam by analysing with pattern identification of modern Traditional Korean medical patholgy as more logical, systematic and standardized theory. Disease pattern mechanisms of essence, spirit, qi and blood in NaeGyungPyeb of DongEuiBoGam are these. In Essence, this explain mechanism of disease patterns those are seminal emission, dream emission, spermatorrhea, white ooze. These disease pattern's mechanisms are kidney yang deficiency, kidney yin deficiency, heart yang deficiency, heart yin deficiency, heart qi deficiency, spleen qi deficiency and so on. On viewpoints of viscera and bowels they are related with heart, kidney, spleen. And most of them are deficiency from deficiency-excess Pattern Identification. Classifying disease pattern of qi is about upward, downward movement and more concentrated deficiency than excess pattern. Fright palpitations can be classified heart deficiency with timidity, heart blood and qi deficiency, heart qi deficiency, heart blood deficiency, heart qi movement stagnation, water qi intimidating the heart, phlegm-fire harassing the heart, phlegm clouding the pericardium, and so on. Palpitations can be classified heart blood deficiency, heart yin deficiency, heart deficiency with timidity, heart spleen blood deficiency, spleen qi deficiency, phlegm-fire harassing the heart, intense heart fire, and so on. Forgetfulness can be classified heart spleen blood deficiency, heart spleen qi deficiency, kidney essence deficiency, heart qi deficiency, non-interaction between the heart and kidney, etc. for deficiency pattern, phlegm clouding the pericardium for excess pattern. In Blood just say inside bleeding pattern's category, there are nose bleeding, flopping syncope, qi counterflow, blood vomiting, hemoptysis, spitting of blood, bloody stool, hematuria, and so on. Like these, this study identify pattern of disease in DongEuiBoGam by mechanism of disease theory.
