  • In this paper, we form the basis of the abstract theory for constructing the $K{\ddot{u}}nneth$ spectral sequence for a complex of Banach spaces. As the category of Banach spaces is not abelian, several difficulties occur and hinder us from applying the usual method of homological algebra directly. The most notable facts are the image of a morphism of Banach spaces is not necessarily a Banach space, and also the closed summand of a Banach space need not be a topological direct summand. So, we consider some conditions and categorical terms that fit the category of Banach spaces to modify the familiar method of homological algebra.

  • 정확한 closed-form 근린함수 계산방법은 공간영역 그린함수에 포함된 Sommerfeld 적분의 계산시간을 줄이기 위해 기존에 이용되어온 복소 영상법(Complex image method)과 2단계 근사화법(Two-level approach)에 비해 훨씬 적은 오차를 갖는다. 본 논문에서는 정확한 closed-form 그린함수 계산방법을 일반적인 전원을 포함하는 평판구조에 적용하는 방법을 제안하였다.

  • Development of distributed simulation environment must be required in order to simulate the distributed models regionally and inter-operate with running simulations individually, Simulation based on DEVS formalism is difficult to simulate the distributed models. DEVS formalism is modeling methodology. To specify model, this formalism separates behavior and structure, therefore it is able to design complex model easily. HLA is standard framework of distribute simulation environment, It is defined to facilitate the interoperability and the reusability. RTI (Run Time Infrastructure) is software that provides common service to simulation systems and implementation of the HLA Interface Specification. Method of implementation is that modules cooperating with RTI are added to simulator on DEVS simulation environment. On the DEVS simulation environment (DEVS-Obj -C) that already developed, Highest class of abstract simulator uses service that RTI provide, then This environment is able to change DEVS model into Federate and run distribute simulation that inter-operates with the RTI. Because this distributed simulation environment includes convenience of modeling that obtains through the DEVS formalism and accompanies HLA standard, this environment make it possible to simulate with_ complex systems and heterogeneous simulations

  • Abstract - The Evodiae Fructus is known for containing a number of indolquinazoline and quinoline type alkaloids. Evodiamine, evocarpine and rutaecarpine are the major constituents of alkaloids. These alkaloids were isolated and determined by forming complex compounds from Evodiae Fructus in O-Su-You-Tang. For the determination of these alkaloids, a new spectrophotometric method was developed with a simple and selective sample clean-up using thiocyanatocobaltate[II] compIεx compound ion. The absorbance of alkaloidal complex compounds in 1,2-dichloroethane solution was measured at 625 nm. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in O-Su-You-Tang.

  • The purpose of this study was to extract protypes from features and concrete images of Lotus and Crane patterns. A qualitative and a quantitative methods were used. Qualitative informations were obtained from depth Interviews for pattern selection and feature extraction, and quantitative informations from a quail-experiment for pattern caregorization. The subjects were 20 female design students and non-design, students in Teajon. The results were summerized into a similarity metrix which was interpreted by the cluster analysis and the multi-dimensional scling(MDS). The patterns for the study were grouped into 8 clusters. Four dimensions were chosen for the MDS. The location of each pattern was visualized in a 2-dimesional spaces and the location of each cluster in a 3-dimensional spaces. The first dimension, "Lotus" vs "Crane" refired to pattern types, and the second dimension, "realistic" vs "transformable", the transformability. The third dimension, "simple" vs "complex", refired to the degree of simplification, and the forth dimension, "continuous" vs "discontinuous", continuity. The results of the Quantitative analysis could be summerized into 3-level prototype hiararchy In the first level, the patterns were devided clearly into two groups. Lotus and Crane by pattern types. In the second levelk, each group was devided into twosubgroups by continuity. In the third, each subgroup was divided into four subgroups by transformability and the degree of simplification. Four protypes, the final targets of the present study, were extracted from the third level. The are Stylized, Realistic, Decorative, Abstract types.d from the third level. The are Stylized, Realistic, Decorative, Abstract types.

  • 본 논문은 레스터 기반 위성영상에서 공간정보를 추출하기 위한 공간 관계 연산 방법과 예를 보인다. 복잡하고 다양한 현실 세계를 지리 정보 시스템은 추상화하고 단순화한 형상을 기반으로 구축한다. 추상화된 지형지물은 지리 객체와 지리필드로 구체화한다. 지리객체와 지리필드는 각각 벡터와 레스터로 표현한다. 레스터 자료형 위성영상은 원격탐사 응용에 이용한다. 원격탐사 공간 정보 추출을 위하여 위상 연산과 기하연산을 한다. 레스터형인 위성영상을 유연성이 뛰어난 벡터화된 객체로 변환하고 이로부터 공간 정보를 추출한다. 원격탐사에 위성영상의 활용이 증가하고 있으며, GIS와 접목함으로써 위성영상 활용의 극대화에 기여 할 것이다.

  • The shape of floral Pattern in the Period of Baroque could be divided single. bunch and vine. The style of representation was stylized, abstract and realistic. the most of style was stylized. The type of composition was fullness, independent and scattered. Floral patterns were shaped simple and complex and components of design could be classified into flower and leaf. flower and fruit. flower and band. bunch of flower, flower and geometry. flower and pot, flower and animal. flower and crest. Kinds of flower were tulip. common marigold, lily, carnation, small bel]flower. lotus, acandus leaf, pomegranate, strawberry. pine cone and abstract anonymous flower which were unfolded by repeat. Characters of floral Pattern were classical elegance, taste of royalty and lively and damask, velvet, brocade which made with gold and silver so, those were a very brilliant and gorgeous. Characters of design were illustrated plane style and stylization where developed arranged on front by repeat or repeat symmetric of vertical. Art, costumes and textiles in this era were a very rich and colorful. The result of study on Baroque's floral pattern will be used to develope a various textile design and chance to be adopted classical pattern into aesthetic value in our time.

  • Let $\mathcal{F}(B)$ be the Fresnel class on an abstract Wiener space (B, H, ${\omega}$) which consists of functionals F of the form : $$F(x)={\int}_H\;{\exp}\{i(h,x)^{\sim}\}df(h),\;x{\in}B$$ where $({\cdot}{\cdot})^{\sim}$ is a stochastic inner product between H and B, and $f$ is in $\mathcal{M}(H)$, the space of all complex-valued countably additive Borel measures on H. We introduce the concepts of an $L_p$ analytic Fourier-Feynman transform ($1{\leq}p{\leq}2$) and a convolution product on $\mathcal{F}(B)$ and verify the existence of the $L_p$ analytic Fourier-Feynman transforms for functionls in $\mathcal{F}(B)$. Moreover, we verify that the Fresnel class $\mathcal{F}(B)$ is closed under the $L_p$ analytic Fourier-Feynman transform and the convolution product, respectively. And we investigate some interesting properties for the $n$-repeated $L_p$ analytic Fourier-Feynman transform on $\mathcal{F}(B)$. Finally, we show that several results in [9] come from our results in Section 3.

  • In examining the relationship between fashion and art which are intimately interrelated, the body is a suitable subject in that it is the common object of representation. This study investigates and compares the images of the body in Francis Bacon's paintings from 1940s to 1970s and the formative aspect and aesthetic value of the abstract body images in Rei Kawakubo's designs since 1980s. The figures in Bacon's paintings are confusingly and atypically deformed as well as distorted, which are the combinations of the anatomies without references, not so much represented objects as experienced sense. Kawakubo's designs attempt to deform the body, moreover, she transforms the body; represent abstract forms without association with any other figures that exist, emphasizing sculptural or architectural shapes of garment. She suggests extensive visual language of dress by challenging the norms of beauty. The body in Bacon and Kawakubo's works is dispersive as well as complex in that the body images are deconstructed, fragmented, and exaggerated. Respectively, they articulate the perception of the body in postmodernism era by destroying the myth of subject; furthermore establish the aesthetics that transcend conventional ideals by reevaluating as well as refusing the standards of beauty.
