The purpose of this study was to construct fashion banner advertising strategy. For this purpose, the following hypotheses were set up : (a) analyze the present state of the fashion banner advertising, (b) examine whether it is any difference of the fashion banner advertising by their demographic variables, media using groups, clothing involvement and brand loyalty. A sample of 553 people in the age group 16-34s living in Seoul were selected from internet users. The data were analysed with Frequency, Percentage, ANOVA. Duncan test by using SPSS Package. The results of this research were as follows : First, fashion banner advertising took the first step. there was small in number. Second, it was found that the attitude of fashion banner advertising had some difference depending on their demographic variables, media usage groups, clothing involvement and brand royalty. Female in lower age groups were greater interests in illustrated/inquisitive fashion banner advertising. And high involvement groups preferred the fashion banner advertising.

Security system with web camera remarkably has been developed at an Internet era. Using transmitted images from remote camera, the system can recognize current situation and take a proper action through web. Existing motion detection methods use simply difference image, background image techniques or block matching algorithm which establish initial block by set search area and find similar block. But these methods are difficult to detect exact motion because of useless noise. In this paper, the proposed method is updating changed background image as much as $N{\times}M$pixel mask as time goes on after get a difference between imput image and first background image. And checking image pixel can efficiently detect motion by computing fixed distance pixel instead of operate all pixel.

With the recent rise of apartment houses, the Korean government set up the Apartment House Manager System in 1989. In fact. a similar was originally introduced and fully settled down in England where the apartment house have been developed for a while. This study is primarily concerned with the comparison of apartment house manager system between Korea and England, with special respect to the background, the department in charge, the qualification of examinees, and the subjects for examination. The first part of this study deals with the difference of system between Korea and England. Among the most salient difference is that the system of Korea was established by the gorvernment itself in order to solve some problems derived from management, whereas that in England came into being for citizens to help the poor with housing problems as a Chrisitian social movement. The second part of this study suggests that it is necessary to open a department of apartment house at the two-year colleges. In addition, it would be advisable to give some advantages such as full a partial exception from examination to those who graduate from four-year universities or colleges.

This paper introduces and illustrates the results of a new method fer offsetting triangular mesh by moving all vertices along the multiple normal vectors of a vertex. The multiple normal vectors of a vertex are set the same as the normal vectors of the faces surrounding the vertex, while the two vectors with the smallest difference are joined repeatedly until the difference is smaller than allowance. Offsetting with the multiple normal vectors of a vertex does not create a gap or overlap at the smooth edges, thereby making the mesh size uniform and the computation time short. In addition, this offsetting method is accurate at the sharp edges because the vertices are moved to the normal directions of faces and joined by the blend surface. The method is also useful for rapid prototyping and tool path generation if the triangular mesh is tessellated part of the solid models with curved surfaces and sharp edges. The suggested method and previous methods are implemented on a PC using C++ and illustrated using an OpenGL library.

In this paper, a fuzzy prediction method is proposed for time series data having uncertainty and non-stationary characteristics. Conventional methods, which use past data directly in prediction procedure, cannot properly handle non-stationary data whose long-term mean is floating. To cope with this problem, a data preprocessing technique utilizing the differences of original time series data is suggested. The difference sets are established from data. And the optimal difference set is selected for input of fuzzy predictor. The proposed method based the Takigi-Sugeno-Kang(TSK or TS) fuzzy rule. Computer simulations show improved results for various time series.

A new scheme to measure the rotor time constant and to set the slip gain of a vector-controller is presented. The approach utilizes the phase difference between the torque producing component of the stator current and rotor current in the stationary frame. It is shown that the rotor time constant can be uniquely identified by detecting the corresponding phase difference. The simulation was carried out by considering the variation of other parameters and the torque producing component of the stator current frequency.

부울 미분의 개념을 응용하여, Allen-Givone implementation oriented algebra에 의한 다치 논리 회로내의 결함을 해석했다. 회로내의 모든 라인을 그 성질에 따라 다섯 가지 유형으로 분류하였으며 각 유형별로 완전한 테스트 세트를 표현하는 식을 유도하고 증명했다. 이들 식의 실제 응용예의 결과는 진리표와의 비교에 따라 옳음이 확인되었다.

In this paper, we solve the three-dimensional biharmonic equation with Dirichlet boundary conditions of second kind using the full multigrid (FMG) algorithm. We derive a finite difference approximations for the biharmonic equation on a 18 point compact stencil. The unknown solution and its second derivatives are carried as unknowns at grid points. In the multigrid methods, we use a fourth order interpolation to producing a new intermediate unknown functions values on a finer grid, and the full weighting restriction operators to calculating the residuals at coarse grid points. A set of test problems gives excellent results.

The Ferrule for the Optical Communication Connector is the product to set the optical ares of an optical fiber very precisely. Therefore, it is required high expectations such as high dimensional precision and new including flaws. Up to new the optical instrument has been used for the defeat and shape inspection of the ferrule, but in the paper we examined the detectable defeat and expectation by using Resonant Ultrasound Spectroscopy(RUS). The RUS is the measurement which is to excite specimen and to inspect the difference at natural frequency pattern between acceptable specimen and specimen which has some defeats. We analyzed the difference of natural frequency pattern in the experiment using Spectrum Analyzer. And we compared the results in the experiment with those in the simulation from the explicit finite elements code, Nastran.

The effect of a solute concentration difference on the osmotic transport of water through the semi-permeable membrane of a simple cell model is investigated. So far, most studies on osmotic phenomena are described by simple diffusion-type equations ignoring all fluid motion or described by Stokes flow. In our work, as the governing equations, we consider the coupled full Navier-Stokes equations which describe the fluid motion and the full transport equation that takes into account of convection and diffusion effects. A two dimensional finite difference model has been developed to simulate the velocity field, concentration field, and semi-permeable membrane movement. It is shown that the cell swells to regions of lower solute concentration due to the uneven water flux through the semi-permeable membrane. The simulation is applied on a red blood cell geometry and the relevant results are presented.
