We investigated the rate of hepatitis G virus infection among 50 patients who were not infected with the hepatitis C virus but showed symptoms of hepatitis. Viral RNA was extracted from the patients' sera and cDNA was synthesized and amplified by RT-PCR (reverse transcription-polymerase chain reaction) using random hexamer and 5 primers (470-20-1-77F, 470-20-1-211R, 470-20-1-211R-biotin, GV57-4512MF, GV57-4657MR). The amplified PCR products were confirmed by electrochemiluminescence (ECL), liquid hybridization (LH) and Southern blotting (SB). Among the 50 PCR products, by means of ECL, we found 4 samples to be positive and 5 samples to be indeterminate. The GV45-89M probe (5'-CYCGCTGRTITGGGGTGTACfGGAAGGC-3') was end-labelled with gamma-$^{32}P$ ATP and used for liquid hybridization with the PCR products. By using liquid hybridization, we detected specific bands from 4 positive sera and also from one indeterminate serum as determined by ECL. An 1.5% agarose gel electrophoresis of the 9 PCR products which were HGV positive or indeterminate as determined by ECL showed a 160bp band from 4 positive and one indeterminate serum. The 5 PCR products proved to be positive when SB was applied with the GV45-89M probe as well as when LH was applied. LH and SB were shown to have higher sensitivity and specificity than ECL. Two cases among 5 positive cases had relatively high SGOT, SGPT, ALP values when compared with other 48 cases. In summary, we confirmed hepatitis G virus infection in 5 cases among 50 Korean patients showing symptoms of viral hepatitis.

이 논문에서는 전편 논문에서 제안한 부정정 스트럿-타이 모델 및 하중분배율 결정식을 ACI 318M-08 스트럿-타이 모델 설계기준에 적용하여 파괴실험이 수행된 51개 연속지지 철근콘크리트 깊은 보의 극한강도를 평가하였다. 또한 연속 깊은 보의 극한강도를 실험식, 실험 및 이론 전단강도모델에 기초한 설계기준, 그리고 현 스트럿-타이 모델설계기준 등으로 평가하고, 그 결과를 이 연구의 방법에 의한 결과와 비교분석하여 이 연구에서 제안한 방법의 적합성을 검증하였다. 이 연구의 방법은 기존의 여러 방법에 비해 극한강도를 비교적 양호하게 평가하였으며, 또한 극한강도평가 시 연속 깊은 보의 강도 및 거동에 영향을 미치는 전단경간비, 콘크리트의 압축강도, 그리고 휨철근비 등 주요설계변수들의 영향을 기존 방법들에 비해 정확하고 일관성 있게 반영하였다. 따라서 이 연구의 방법은 부정정 스트럿-타이 모델 방법을 이용한 연속 깊은 보의 합리적이고 실용적인 설계를 가능하게 할 것으로 판단된다.

Throughout this paper, all rings are assumed to be commutative with identity. By a local ring (R, m), we mean a Noetherian ring R which has the unique maximal ideal m. By dim(R) we always mean the Krull dimension of R. Let I be an ideal in a ring R and t an indeterminate over R. Then the Rees algebra R[It] is defined to be(omitted)

Th purpose of this study is three folds: to analyze postmodern fashion through the notion of pastiche to enhance an understanding of uncertain and confused situation in the late 1990s and to suggest a way of approach to creativity and originality in recent fashion design. The results can be summarized as follows: 1. Pastiche is an art work that borrows some parts of other artists authentic works and recombines them thus imitating their style technique or motifs selfconciously. 2. Pastiche is based onthe Deconstruction theory: the end of art as a result of deconstruction of the subject the collapse of the meaning the loss of history: the late Capitalism in which reality becomes chage into images or simulacre. 3. Pastiche represented by the death of author which means the exhaustion of creativity is shown in the fashion borrowing subculture styles and art works or religious images. Pastiche fashion which is equal to the play of signifiers floated as image is shown as graffiti and objects Time and space pastiche fashion can be explained by historical eclectism and ethnic looks, Finally pastiche means not the fixed aspect but the open concept of indeterminate condition which includes " anything goes" through the coesistence of various style in pastiche fashion.

In this paper, we first present a method for finding the implicit equation of the curve given by rational parametric equations. The method is based on the computation of $Gr\"{o}bner$ bases. Then, another method for implicitization of curve and surface is given. In the case of rational curves, the method proceeds via giving the implicit polynomial f with indeterminate coefficients, substituting the rational expressions for the given curve and surface into the implicit polynomial to yield a rational expression $\frac{g}{h}$ in the parameters. Equating coefficients of g in terms of parameters to 0 to get a system of linear equations in the indeterminate coefficients of polynomial f, and finally solving the linear system, we get all the coefficients of f, and thus we obtain the corresponding implicit equation. In the case of polynomial surfaces, we can similarly as in the case of rational curves obtain its implicit equation. This method is based on characteristic set theory. Some examples will show that our methods are efficient.

This paper is a sequel to our paper [3]. Although polynomials in the tianyuanshu induce perfectly the algebraic structure of polynomials, the tianyuan(天元) is always chosen by a specific unknown in a given problem, it can't carry out the role of the indeterminate in ordinary polynomials. Further, taking the indeterminate as a variable, one can study mathematical structures of polynomials via those of polynomial functions. Thus the theory of polynomials in East Asian mathematics could not be completely materialized. In the previous paper [3], we show that Jeong Yag-yong disclosed in his Gugo Wonlyu(勾股源流) the mathematical structures of Pythagorean polynomials, namely polynomials p(a, b, c) where a, b, c are the three sides gou(勾), gu(股), xian(弦) of a right triangle, respectively. In this paper, we show that Jeong obtained his results through his recognizing Pythagorean polynomials as polynomial functions of three variables a, b, c.

The formative exaggeration phenomenon, which makes the plastic space, escaping from the form peculiar to the human body, is being developed into the more diversified and abstract structure. This study analyzed the form and shape of costumes with objective attitude through the use of an oppositional concept method, which Delong presented from the formative viewpoint. Delong's theory, which was presented in this study, can be said to be one index that analyzed the form and shape of costumes. The costumes of the Renaissance Era, in which formative exaggeration is remarkable, are determinate in that they are closed and static, and can be classified into part, planer separation, and flat. The costumes of the Baroque and Rococo Eras are divided into similar formative perspectives, and can be said to be open, whole, and integrated due to indeterminate and diverse decorations. Entering modern times, the formative-exaggeration phenomenon in costumes of the Romantic Era are characterized by closed, part, and planer separation similar to costumes of the Renaissance Era. However, in the aspect of sleeve design and decoration, the characteristics of determinate and indeterminate were considered.
