This paper presents a landscape design for the citizen plaza around the ˝Woojeongchongkuk˝(the 1st Korean postal building) where the ˝Gapsinjeongbyeon˝(1844 coup d´etat) occurred and which was once used as the ˝Jeoneoigam˝(a palace hospital). The site is located in 39 Kyeonji-dong, Jongno-gu, Seoul, and of which area is about 2,013$m^2$. The landscape design goals are to build traditional spaces which fit the traditional buildings and where people feel the old atmosphere; to build interesting spaces where people can learn the post and telegraphic history; and to build nature-friendly green rest spaces in the city. To achieve these goals, symbolic, traditional, educational, historical, and environmentally-friendly concepts are developed. With this concept the space is divided into two axis of the pst and telegraph of Korea. Along the two axis the Postage Stamp ˝Madang˝(yard), the Letter Garden, the Telegraphic ˝Ddeul˝(garden), the Communication Plaza, and the ˝Jeoneoigam˝(old palace hospital) and the ˝Gapsinjeongbyeon˝(1884 coup d´etat) Memorial Place are arranged. The Postal Stamp Madang which symbolizes the first Korean postage stamp is a space for studying history and evolution of stamps in Korea. The Letter Garden which symbolizes and formalizes a letter paper is composed with white bamboo trees which are planted linearly and long granite benches on which famous letters are carved. In the Telegraphic Ddeul which symbolizes the telegraph, the history of the telegraphic instrument and the telephone is exhibited. In the Communication Plaze which symbolizes future post and telegraph service extending to the world, the images of satellite communication, internet, webmail etc. are exhibited. The Jeoneoigan, and the Gapsinjeongbyeon Memorial Place is for memorializing the historic place and events. Throughout the whole place, various models and ceramic picture tiles about the post and telegraph and exhibited for effective education. In conclusion, sustainable management schemes for the site are suggested.

In this study, we showed understanding and production ability of the interface about internet, operating system, contents, and devices. This study aimed to make a list of 18 items in 4 areas for basic knowledge of UI/UX, establishment of design research, design concept, and design production for 22 sophomore, junior and senior students in IT departments, and the results of understanding were divided into three groups of excellent, normal, and insufficient, and evaluated. It was found that excellent was 18.39%, average was 38.52% and insufficient was 43.07%. Therefore, 18.39% of the students understood UI/UX, and 81.61% of students did not understand UI/UX well. In particular, in the comparison analysis of four areas, the design research area was 44 points, the design content area was 29 points, and the design production area was 11 points which was found to be the lowest. Next, the 10 evaluation items in the mobile UI/UX build guide evaluation were evaluated in the same way as the UI/UX understanding, and the excellent score was 3 points, the average score was 73.3 points, and the poor score was 155 points. The UI/UX build guides showed worse evaluation than UI/UX understanding. Therefore, to cultivate UI/UX understanding and content production ability, UI/UX experts should be fostered with professional course organization and systematic curriculum.

In the development of large complex assembly, most design changes are from the following reasons.: 1) insufficient consideration of assembling sequence of downstream process. 2) interference and fit-up of related parts. 3) initial design changes which are not completely resolved. In order to reduce the first reason of above, the assembly-centric modeling methodology was proposed in the part (1) of the thesis. In this part (2), a Digital Mock-Up system, which is a tool to build a virtual mock-up in design stage, has been developed in order to prevent the other two reasons. The system can build a virtual assembly in various ways as followings.: 1) assembling parts which are located in user defined envelope. 2) assembling parts with the specified disciplines. 3) assembling parts that are selected in the part list. It can also make an assembly by the combination of above methods. In addition to that, it has the functions to read/write the virtual assembly and to explode parts of the assembly in desired direction. With the virtual assembly, engineers can design interference free parts without making physical mock-up. The system has been implemented with Oracle database management system in CATIA environment.

이 설계 과정은 보통의 더지탈 하아드웨어 담계에 복합 기계 개념을 응용한 일설계 기법을 소개한 것이다. 이 과정은 계산기용 소프트웨어 설계의 경우와 마찬가지로 새 시스템을 흐름도에 의해 표현시키는 것으로 부터 시작되며, 이어서 흐름도를 분해하여 발산형 요소를 얻고, 이 발산형 요소를 근거로 소기계를 작성하게 되는데, 이렇게 소기계의 작성이 끝나게 되면. 이번에는 통합 과정을 통해서 복합체와 지시기를 만들고, 논리자로를 완척함으로써 전휴의 설계 과정을 완료하게 된다. This is an introduction to an art of digital hardware design using polymachine image as a target structure of the product. As in the case of software design of a computer, the design process begins with a sketch of planned system in flow chart description and the flow charts is partitioned into divergent elements. Each of the element machine is derived from those divergent elements. We can build a complete digital system with the preparation of an index, and a polymer of these element machines.

Rapid Prototyping (RP) techniques have their unique characteristics according to the working principles: stair-stepped surface of parts due to layer-by-layer stacking, low build speed caused by line-by-line solidification to build one layer, and additional post processing to improve surface roughness, so it is required very high cost to introduce and to maintain RP apparatus. The objective of this study is to develop and design a new RP process, Variable Lamination Manufacturing using expandable polystyrene foam sheet as part material (VLM-S), which can make up for the disadvantage of existing techniques, and to develop an apparatus to implement the process. In order to examine the possibility of practical utilization of the proposed VLM-S process for prototyping of a general three-dimensional shape, an auto-shift lever knob and a pyramid shape were fabricated.

For effective part modifications which is necessary in the design process frequently, variational geometric modeling with constraint management being used in a wide. Most variational geometric modeling methods, however, manage just the constraints about sketch elements used for generation of primitives. Thus, not only constraint propagation but also re-build of various modeling operations stored in the modeling history is necessary iota part geometry modifications. Especially, re-build of high-cost Boolean operations is apt to deteriorate overall modeling efficiency abruptly. Therefore, in this paper we proposed an algorithm that can handle all geometric entities of the part directly. For this purpose, we introduced eight type geometric constraints to the various geometric calculations about all geometric entities in sweepings and Boolean operations as well as the existing constraints of the sketch elements. The algorithm has a merit of rapid part geometric modifications through only constraint propagation without rebuild of modeling operations which are necessary in the existing variational geometric modeling method.

Characteristics of a fusion-driven transmutation reactor was investigated. A compact reactor concept is desirable from an economic viewpoint. For the optimal design of a reactor, a radial build of reactor components has to be determined by considering the plasma physics and engineering constraints which inter-relate various reactor components. In a transmutation reactor, design of blanket and shield play a key role in determining the size of a reactor; the blanket should produce enough tritium for tritium self-sufficiency, the transmutation rate of waste has to be maximized, and the shield should provide sufficient protection for the superconducting toroidal field (TF) coil. To determine the radial build of the blanket and the shield, not only a radiation transport analysis but also a burnup calculation were coupled with the system analysis and it allowed the self-consistent determination of the design parameters of a transmutation reactor.
