Hi Seoul과 해치로 대표되는 서울시의 상징체계를 커뮤니케이션의 의미론적 모델을 통해 분석하였다. 세계주요 도시의 상징 디자인 사례를 조사하였으며 이를 기반으로 서울시 상징체계의 문제점과 성과를 분석하였다. 도시 슬로건으로서의 Hi Seoul은 서울시의 의도와는 달리 목표대상이 되는 외국인들에게 어떠한 의미로도 인식되거나 공유되지 못하고 있다. 도시 상징으로서의 해치는 선정과정에서 많은 논란이 있었으나 일단 서울시민들에게는 서울시가 의도한 의미가 비교적 인식되고 공유되고 있다 평가된다. 그러나 외국인의 해치 이미지에 대한 접근성은 개선해야 할 필요가 있다. This thesis analyzes the symbol system of the Seoul Metropolitan Government that is represented by “Hi Seoul" and "Haechi" through the semantics model of communication. It studies the cases of symbol designs of other major cities in the world, and based on that, examines the problems and achievements of the symbol system of the Seoul Metropolitan Government. The city slogan "Hi Seoul" has not been either perceived or shared in any ways by foreigners, one of the target groups, which is the result far from what the city government has intended. The process of selecting "Haechi" as the city symbol stirred up many controversies, but the meaning that the city government intended to instil is evaluated to be relatively well appreciated and shared by the citizens of Seoul for now. Nevertheless the accessibility to "Haechi" for foreigners still needs to be improved.

비정형 Diagrid System의 내진성능 평가

고창균,주영규,김상대,Ko, Chang-Kyun,Ju, Young-Kyu,Kim, Sang-Dae 한국강구조학회 2011 韓國鋼構造學會 論文集 Vol.23 No.2

최근 건축물들이 미적인 아름다움을 추구하며 점차 비정형화 되어감에 따라 이를 실현시켜 주기 위한 새로운 구조시스템들이 개발되고 있다. Diagrid system은 외각에 배치 된 경사진 기둥을 통해 구조물의 중력하중과 횡력을 모두 저항하는 시스템으로 건물 내부에 기둥이 없어 비교적 평면 변화에 유리한 시스템이다. 하지만 현행의 내진설계 기준에는 이와 같은 새로운 구조시스템에 대한 내진성능계수가 명시되어 있지 않다. 이에 새로운 내진성능 평가 방법인 ATC-63이 제안되었다. 본 논문에서는 구조물의 비정형성을 고려해주기 위해 3D 비선형 해석 모델에 각각 작용하는 하중의 방향을 달리하며 ATC-63에서 제시하고 있는 절차에 따라 비정형 Diagrid system의 내진성능을 평가하였다. Many new structural systems have been developed to build free-form structures, which is the new architectural trend for aesthetic beauty. The diagrid system resists both gravity and later loads, with its perimeter-diagonal columns. In the current seismic-design provisions, however, a seismic-performance factor for a new structural system has not yet been provided. ATC-63 provides a new methodology for defining various seismic-performance factors, including the response modification factor. In this paper, nonlinear static and dynamic analyses were conducted for the 3D diagrid frame, with each load applied at $0-180^{\circ}$ degrees. Through these analyses, the seismic performance of the diagrid system was evaluated.

서울의 정체성을 위한 경관조명계획의 연구 및 제안

박인창 ( Park In-chang ),고창균 ( Ko Chang-kyun ) 한국디자인트렌드학회 2011 한국디자인포럼 Vol.33 No.-

도시의 이미지는 과거로부터 이어져온 역사적, 문화적 이미지와 현재 가꾸어 나가는 모습이 합쳐져서 생성된다. 즉 도시는 현재 가지고 있는 이미지와 도시의 구성원들이 새로운 이미지를 생산함으로써 새로운 도시이미지를 형성한다. 도시의 정체성은 그 도시의 역사, 과거와 현재의 문화, 경제활동을 영위하는 시민들의 시민의식이 포함된다. 도시의 정체성을 위해서 상업공간과 공적인 공간이 재정비되고 있다. 최근에 쾌적한 공간을 위한 사업으로 도심의 오아시스 공간 만들기, 교류가 있는 활기찬 가로 만들기, 즐겁게 보행할 수 있는 가로 만들기, 아름다운 가로 만들기 등 도시의 정체성을 재구성하려는 노력이 증가 되고 있다. 구체적인 내용으로는 거리시설물, 건물의 높이, 외벽의 재료와 색채, 건축물의 간격 및 건축면적, 일층부의 형태, 건축설비, 광고물 관리 등의 관리 가이드라인과 이에 대한 새로운 표준화 매뉴얼이 개발되고 있다. 이러한 상황을 배경으로 본 논문은 밤에 보여 지는 도시의 매력이 낮과는 다른 도시의 이미지를 보여주기 때문에 야간 경관을 중심으로 한 경관관리의 필요성과 도시마케팅의 사례를 분석한다. 특히 역사적인 궁궐과 한옥이 현대적인 건축물과 공존하는 서울의 정체성을 구축하는 방법으로써 조명계획에 대한 위계(位階)기준을 제안하여 `한국다움`과 `서울다움`을 만드는 시각적인 야간경관의 자료로써 활용토록 한다. The image of a city is created by the combination of historical culture and today`s construction. The identity of a city includes it`s history, culture and citizen`s spirit. Nowadays, many cities are reorganizing commercial and public space to create it`s own identities. In public space, there are many construction works such as making oasis in downtown, creating vibrant street, designing street furnitures and compiling a guideline that includes height limit of buildings, hoarding restriction, materials and colours of buildings, distance between buildings and shape of ground floor. In these background, this study will investigate the importance of landscape lightings for city identity and analyse city marketing. Especially, for the way of build up city identity and apply it as a tool for find out real `Seoul`, this study will propose the hierarchy of landscape lightings.

Buckling Restrained Braces(BRBs) show good seismic behavior. They do not dissipate energy, however, when they are subjected to wind. Hybrid Buckling Restrained Braces(H-BRBs), which can improve the wind performance of the BRB system, are a kind of hybrid damper system composed of a viscoelastic damper and BRBs. In this paper, the H-BRBs subjected to wind load was explored in the method of time history analysis for 3-dimensional model. The wind load for serviceability design was obtained from the wind tunnel test. Along wind and across wind load datas were used. Steel brace, buckling restrained brace, and H-BRB were compared in terms of the roof displacement, the roof acceleration, hysteresis loops. It was concluded that H-BRBs show good performance for the wind load and have improved the high-rise building performance at a serviceability level.

HDTV 방송 프로그램 제작 환경 변화에 관한 연구

정우근,고창균 현대사진영상학회 2001 현대사진영상학회논문집 Vol.4 No.1

Nowadays, all the countries are putting their whole energy into the adaptation of the digitalized broadcasting, confronted by a great revolution in the television broadcasting. The change of the system environment foretells somewhat a change in the form of real production. The digital broadcasting with a new media concept (on the basis of HDTV broadcasting), unlike the existing analogue broadcasting, shows a great change in its function and can supply audience with more advanced service. It is different from the past that audience can select to get more various and stereoscopic information through multicasting, excellent sound effect and vivid picture of high definition and quality. The high definition of HDTV(High Definition Television) broadcasting resulting from this systematic change, however, can't be stably settle down only by the emphasis upon its mechanical characteristics. Therefore, only way through which media of a new concept can be loved by so many people is to satisfy their new desire which they have never experienced by making the most of the characteristics of HDTV. In order to meet the demands of audience, proper programs should be created for HDTV from the stage of their production so that broadcasting can be well operated. In this respect, it would be suggested that staffs related to the actual production of programs must research in advance for the active improvement of changes in the various elements which are significant to the determination of image. This study also aims to find out some problems concerning changes appeared in the process of transfer from analogue system to digital system, with special reference to the techniques of producing programs, and to draw up a plan to solve those problems. In order to discuss problems in this area, it is necessary to survey a brief history of television as media in Korea and the process of its development with the change of the times, to analyze the situation of the age when the present television has been forced to change with the transition of the various elements to determine image. Thus, it is observed that the progress of HDTV showing promise as a new concept absolutely depends upon the production and the broadcasting of programs fir for the characteristics of HDTV. Futhermore, it can be expected that a great change would appear in the production of programs in the process of transition from analogue broadcasting to digital broadcasting. In this respect, in order to analyze this, the frame must be fixed with particular respect to camera, light, and set which are significant elements to image making. HDTV has a peculiar ratio of its screen; 16:9, unlike the existing television, and this feature forces the perspective of angle and camera work to be rearranged. As for light, unlike the style of the existing analogue system, it is required to have so much light, and further study concerning this must be continuously conducted. Because much light is required to this system on the basis of high definition. Under this light system, the detailed scenes such as unnaturalness of unrefined set can be clearly observed, and this can cause a deterioration of quality in broadcasting. All the descriptions and performances that have been concealed on the stage are availably presented as they are. In this respect, all participants in the test broadcasting commonly contend that the imitated wooden set must be replaced by the actual furniture or tools. Therefore, this study attempts to suggest a more affirmative plan about the improvement of techniques in production, because it must be activated in order to play an important role in high definition and quality broadcasting at a minimum of trial and error.
