It has been recognized that the cityscate identity is a very important factor in a modern city. It is necessary to have a variable view to urban comunities for understanding the cityscape identity. We have investigated the contents of archaic texts such as the geography for tracing a cityscape identity to its origin in a city. Because it has been written about politics, economics and culture of a specific area in the geography based on deep interest to the city, we can look into the early image of the cityscape closely after searching of archaic texts. It is also significant to stdy with archaic texts of geography since these studies have a correlatio to the understand of an area and the keeping of historical conscious which are fundamental of cityscape identity. We have studieds on the area of Cheongju from the middle of Chosun dynasty to the end of this kingdom, since that many geographies were described those days. It was selected "Go-Reo-Sa" and "Se-Jong-Sil-Lok" Geography, "Sin-Jeung-Dong-Guk-Y대-Ji-Seung-Lam" "Dae-Dong-Ji-Ji" "Dong-Guk- Yeo-Ji-Ji", "Jeug-Bo-Mun-Heon-Bi-Go Yeo-Ji-Go", and "Taek-Li-Ji", as archaic texts of geography because these texts described in detail about city and gave a clue to speculate an image of city. The major results are as follows; 1) It was described about the cityscape in those archaic texts are metaphysical image, existing and usable elements of cityscape, lost resources of cityscape. 2) The metaphysical images are neither objective nor consistent in the each archaic texts. But the metaphysical image of old city suggests good insight for the application to the modern city image. 3) It is necessary to the careful onsideration about the existing elements. 4) There are variable programs about the lost resources of the cityscape, in accordance with the possibility of the restoraton. 5) The physical and visible factors and non-physical and invisible factors are equally important elements of the cityscape identity. Our research suggests that it is necessary to understand in detail how those factors of cityscape identity have changed with the changes of the times, and how those factors affect the modern cityscape identity.

This work is based on a nonlinear finite-element model with proven capacity for yielding realistic predictions of the response of reinforced-concrete structures under static monotonically-increasing loading. In it, the material description relies essentially on the two key properties of triaxiality and brittleness and, thus, is simpler than those of most other material models in use. In this article, the finite-element program is successfully used in investigating the behaviour of a series of RC walls under static cyclic loading. This type of loading offers a more strenuous test of the validity of the proposed program since cracks continuously form and close during each load cycle. Such a test is considered to be essential before attempting to use the program for the analysis of concrete structures under seismic excitation in order to ensure that the solution procedure adopted is numerically stable and can accurately predict the behaviour of RC structures under such earthquake-loading conditions. This is achieved through a comparative study between the numerical predictions obtained presently from the program and available experimental data.

In this paper, we propose AnoVid, an automated video annotation tool based on deep neural networks, that automatically generates various meta data for each scene or shot in a long drama video containing rich elements. To this end, a novel meta data schema for drama video is designed. Based on this schema, the AnoVid video annotation tool has a total of six deep neural network models for object detection, place recognition, time zone recognition, person recognition, activity detection, and description generation. Using these models, the AnoVid can generate rich video annotation data. In addition, AnoVid provides not only the ability to automatically generate a JSON-type video annotation data file, but also provides various visualization facilities to check the video content analysis results. Through experiments using a real drama video, "Misaeing", we show the practical effectiveness and performance of the proposed video annotation tool, AnoVid.

A two-dimensional FEM program, which considers bending effects in the membrane fromulation, was developed under plane strain assumption for analyzing forming processes of an arbitrarily shaped draw-die of automotive panels. For the evaluation of bending effects with membrane elements, the bending equivalent forces and stiffnesses are calculated from the bending moment computed using the changes in curvature of the formed shape of two membrane ones. The curves depicted with 3 nodes are described by a circle, a quadratic equation, and a cubic equation, respectively, and in the simulation of the stretch/draw sections of an automotive inner panel, three different description results are compared each other. Also, the bending results are compared with membrane results and measurements in order to verify the validity of the developed program.

In this work, a general method for the mathematical description of three-dimensional trimmed surface is proposed by introducing the base parametric surface and boundary curves. Since mesh density distribution for the analysis may vary by cases, a grid-based mesh generation algorithm using quadtree is proposed in the present work. For the assurance of connectivity of generated meshes among surfaces, a method for the pre-cleaning of boundary curves has been developed to be used in the automatic generation of the finite elements. In addition, mesh-smoothing algorithm is suggested which can be used in the general trimmed surface. In this algorithm nodes are moved on the original surface by the normal projection in each iterative smoothing procedure.

In this paper we give a description of students' obstacles in their learning of geometry, especially resulted from their confusing a physical drawing with a figure, a geometrical object which a physical drawing represents. In computer-based teaching-learning environment, we could relieve such obstacles through providing students for experiences in which they must focus on elements of a figure and relations of them. But there may be potential in computer-based environment if we offer students only visual experience for validity of geometrical gacts: students' lack of understanding for need of proof and experience of cognitive obstacles which is very important for students to reflect their thinking and activities. Thus an didactical treatment must follows, which we also give an example.

A large generator is an important role in transferring an electric power to power system. The IEDs of large generator often use microprocessor technology to obtain a digital relay system with a wide range of measuring, protection, control, monitoring, and communication functions. However, all generator protection and control systems in Korea imported from abroad and are being operated. In order to reduce the large expense and improve the reliable operation, development of generator protection and control system by domestic technology is required. This paper deals with the design of the IED of generator protection panel for development of generator protection and control system. The major emphasis of the paper will be on the description of hardware and signal processing test results and measurement accuracy of the prototype IED. By developing of generator IED based on DSP and microprocessor, replacement of the generator protection panel imports are expected to be effective.

This article gives upper bounds on the number of Fourier-Jacobi coefficients that determine a paramodular cusp form in degree two. The level N of the paramodular group is completely general throughout. Additionally, spaces of Jacobi cusp forms are spanned by using the theory of theta blocks due to Gritsenko, Skoruppa and Zagier. We combine these two techniques to rigorously compute spaces of paramodular cusp forms and to verify the Paramodular Conjecture of Brumer and Kramer in many cases of low level. The proofs rely on a detailed description of the zero dimensional cusps for the subgroup of integral elements in each paramodular group.

In comparing with the role, scope, and description method of edition statement between monograph and old traditional books, There are some problems solving as follows : 1) Kind of issue offering information on variant imprint must be distinguished from edition merely identifying the newest thing among same materials in the edition area of old traditional books. 2) because of a rule that edition statement follow title statement according to ISBD, could not make a most of the characteristics of old traditional books. As a result of a n.0, pplication MARC format for solving above the problems, the followings have been identified. 1) Subfield in the 245tag can be made a distinction between kind of issue and edition with when describing edition statement of old traditional books. 2) As defining newly the Fixed-Length Data Elements of Marc format, not only basic index terms, such as author, title, etc., but also edition statement on variant kind of issue will be able to provide with restrict index terms.
