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.

Determination of force system and prediction of side effects from unbent straight wire engaged in edgewise bracket is clinically very difficult because it is statically indeterminate system. This study is to develop a linear beam theory that explains the force system for straight wire engaged in edgewise bracket regardless of geometry(a/b), material, cross section of wire, and interbracket distance. 1. Formula for force system of bilateral fixed end beam was derived. 2. It is possible to calculate force system of each tooth engaged in continuous straight wire. 3. The possibility and location of permanent deformation can be predicted.

Grading and sorting an indeterminate form of agricultural products such as sweet potatoes and potatoes are a labor intensive job because its shape and size are various and complicate. It costs a great deal to sort sweet potato in an indeterminate forms. There is a great need for an automatic grader fur the potatoes. Machine vision is the promising solution for this purpose. The optical indices for qualifying weight and appearance quality such as shape, color, defects, etc. were obtained and an on-line sorting system was developed. The results are summarized as follows. Sorting system combined with an on-line inspection device was composed of 5 sections, human inspection, feeding, illumination chamber, image processing & control, and grading & discharging. The algorithms to compute geometrical parameters related to the external guality were developed and implemented for sorting the deformed sweet potatoes. Grading accuracy by image processing was $96.4\%$ and the processing capacity was 10,800 pieces per hour.

Snap bean is a new corp in Korea but believed to have a great deal of potentials for both domestic and overseas markets. The present study was performed to obtain the basic information about growth- and quality-related characteristics and to determinate the optimum seeding date and harvesting time for snap bean. Pod yield was significantly affected by seeding date. The highest pod yield was obtained from March 20 for determinate type and April 4 for indeterminate one, respectively, with the range of 13.0-23.7 t/ha. The pod length of indeterminate type was over 13cm, and the pod length was over 5 grams. The pod width for tested varieties was less than 1.0cm. Considering the pod growth characters such as pod length, pod width, and pod weight, the optimum harvesting time for immature pods of snap bean was supposed to be from 15 to 20 days after flowering. The daily yield of snap bean was begun to sharply increase from 15 days after the first flowering and the maximum yield was recorded at 30 days after flowering. For the accumulated yield, nearly 90% of total yield was obtained in 42 days after flowering.

The parameter modification of the initial FEM model to match it with the experimental results needs the modal information and the modal sensitivity matrix to the parameter change. There are two cases this methodology is ill-equip to deal with; the deficiency of the necessary modal information and the ill-conditioning of the sensitivity matrix. In this research, a novel concept of the feedback exciter that uses the summation of the white noise and the signals from the measurement sensors multiplied with feedback gains as the reference signal is proposed. There are 2 advantages using this external feedback excitation. First, we can use the change of the system response such as modal data by the active energy Path from the sensor to the exciter. This change of the system response can be additional clues to the system dynamics that we want to know. Secondly, the external energy Path alternates the offset of the Parameter change to the system response. That means the modal sensitivity of the parameters becomes different from the original sensitivities by the feedback excitation. Through the feedback loop, we can change the similar modal sensitivities of some updating parameters and consequently discriminate the parameters using the closed-loop modal data. To demonstrate the discrimination performance, the parameter estimation of an indeterminate structure by use of the feedback method is introduced.

Since modem times, civilization of scientific technology has rapidly expanded and resulted in many negative aspects. Dystopia is a skeptical future standpoint newly introduced by surging awareness of these negative aspects. The purpose of this study is to discover the common characteristics by studying costumes displayed in dystopian films which have critical view of the future. This study is made through the research of sundry records, thesis and capture images from DVD system. As a result of the study, the common formative characteristics of future costumes appearing in six dystopian films are classified into external characteristics and internal characteristics. First, external characteristics were analyzed according to the form, material and color. Second, internal characteristics of costumes appearing in dystopian films are categorized as the indeterminate expression, ex-typical expression and uniform expression. The above formative characteristics of dystopian future costumes can be described as the embodiment of meanings of influence from present and future cultural changes in terms of the characteristics of fashion.

The purpose of this study is to investigate Seonyudo Park and Kkummaru in terms of haptic space. This is also an attempt to explore temporality of appearing in architectural spaces with reference to cinematic expression in which time is visible and perceptible. The film of Chris Marker's La Jet$\acute{e}$e depicts temporal relationship by indeterminate continuum, reading the space on the disjunctive relationships of visual and auditory, and aberrance of time and space. Based on the three categories that is derived from those discussions, this study analyzes the experience of non-chronological time induced by architectural devices: the bifurcation of indeterminate circulation, the readability of space on the disjunction of visual and auditory, and the border-dismantling. Therefore, this study have a relationship with the contemporary discourse on time and events as transformation and becoming, and it means to escape from the deterministic thinking to emphasize invariability and space rather than variation and time.
