Due to the strong relationship between Baekje, one of the ancient Korean Kingdom and Japan through the same religion, Buddhism, it is possible to find many similarities in remains, such as temples, and pagodas, and in many relics, in both cities. However, from the point view of urban planning, Buyeo, originally designed as the fortress city, has a different city planning strategies from that of Kyoto which is a straight-lined city. After Buyeo was destroyed by Silla, one of the Three Kingdoms in Korea, it got deemphasized in Korean history. Later, Buyeo's recent city planning was directly affected and implanted in Japanese Imperialism period (1910-1945) one which emphasizes the layout of Japanese temple which serves as the center of the ceremonies for their ancestors. Thus, it is possible to find cultural interrelation in urban planning between two cities throughout the history of Korea and Japan.

본 연구는 최근 도시의 매력을 높이는 요소로 관심이 높아지고 있는 도시브랜드 개발에 관한 연구이다. 기존의 도시브랜드 아이덴티티 설계의 접근방식은 행정기관이나 도시정부관련 내부이해관계자의 입장에서의 접근이었지만 본 연구에서는 도시의 대표적 외부이해관계자인 소비자입장에서 도시브랜드를 파악 설계하는 접근방식을 취하였다. 즉, 본 연구의 목적은 도시브랜드의 대표적 이미지를 도출하고, 이를 근거하여 소비자행동을 규명하여 도시브랜드 커뮤니케이션에 대한 마케팅전략제시를 목적으로 한다. 연구목적달성을 위해 선행연구를 바탕으로 선도적, 안정적, 유희적 이미지의 3가지 도시브랜드 이미지차원을 도출하였고, 이를 바탕으로 가상의 도시에 대한 3개의 시나리오를 실험자극물로 제작하였다. 실험결과, 가상의 도시에 대한 전반적 도시브랜드태도, 거주의도, 관광의도는 선도적, 안정적, 유희적 이미지에 따라 유의한 차이를 나타냄을 확인할 수 있었다. 이러한 연구결과는 기존의 특정 도시에 대한 제한적 제언의 한계를 벗어나 도시브랜드 이미지에 대한 보편적 시사점을 제공할 수 있을 것으로 기대한다.

In this paper, we propose an efficient multi-view images coding algorithm to find the optimal depth and texture from the set of multi-view images. The proposed algorithm consists of two consecutive steps, i) the depth estraction step, and ii) the texture extraction step, comparedwith the traditional algorithem which finds the depth and texture concurrently. The X-Y plane of the normalized object space is divided into traingular paatches and the Z value of the node is determined in the first step and then the texture of the each patch is extracted in the second step. In the depth extraction step, the depth of the node is determined by applying the block based disparity compensation method to the windowed area centered at the node. In the second step, the texture of the traingular patches is extracted from the multi-view images by applying the affine transformation based disparity compensation method to the traingular pateches with the depth extracted from the first step. Experimental results show that the SNR(Singnal-to- Noise Ratio) of images enconded by our algorithm is better than that of images encoded by the traditional algorithm by the amount about 4dB for for the test sets of multi-view images called dragon, kid, city and santa.

최근 건물정보를 다루는 BIM(Building Information Modeling)과 공간정보를 다루는 GIS(Geographic Information System) 간의 연계 또는 통합을 시도하는 다양한 연구가 이루어지고 있다. 특히, BIM의 표준 데이터모델인 IFC(Industry Foundation Classes)와 GIS 표준 데이터모델인 CityGML 간의 변환에 대한 연구가 시도되었지만, 두 데이터의 특성과 사용목적이 많이 달라서 그 연구결과를 활용하기에는 아직 미미한 실정이다. 이에 본 연구에서는 BIM과 GIS의 상호연계의 가능성을 파악하기 위하여 IFC와 CityGML의 LOD(Level of Detail)별 객체 간의 특성을 분석하였으며, 이러한 분석 내용을 바탕으로 빌딩 관점에서 IFC와 CityGML의 객체 간의 매핑을 수행함으로써 IFC와 CityGML 간의 연관성을 분석하였다. 이러한 연관성 분석 결과를 기반으로 본 연구에서는 IFC와 CityGML 간의 좀 더 효율적인 연계방안을 제시하였다.

This study aims to draw out planning principles and structure of Iksan imperial capital city in late Baekje, especially in view of the relationship among imperial capital city planning area, skeletal axis and the location of royal castle. With site survey and analysis of historical records, old maps, topographical maps, archeological excavation data, land registration map of 1915, some significant inferences were drawn out. Firstly from the point of topological conditions, the contiguous line of a stratum from Mireuk mountain(彌勒山) to Wangkung-ri castle(王宮里遺蹟) and two waterways made a topological axis of Iksan Imperial capital city. Secondly district of Iksan imperial capital city can be deduced to the inner area north to Kummado soil wall(金馬都土城), south to the confluence of Iksan river(益山川) and Busang river(扶桑川), west to Okum mountain fortress(五金山城) and Galjeon river(葛田川), east to line near to eastern wall of Jesuksa temple(帝釋寺). Iksan ssang-reung(益山雙陵) was located outside western boundary line of capital city. Thirdly axis from Wangkung-ri castle to northern Kummado soil wall made a skeletal axis of city structure. It got through northern lowland along Buk river(北川) between Yonghwa(龍華山) and Mireuk mountain. Fourthly the location of royal palace can be deduced to the north part of the city around Kumma town area along the planning principle of northern royal palace.

In this research, we have performed a T-test to see how the relationship between dependent variable or visual point level and independent variable or visual quantity is in order to clear up the correlation between pattern of visual point and visual quantity by the constituents of a view from a different visual point level and the results are as follows: 1) In case of the character of Mt. Uam landscape of the city, Uamsan is set as a fixed point and about a direction of view(D), the north is a datum point from which the range of direction is distributed within 1800 westwardly and the visual range(R) is also within 2000m. An elevation is an average of 7.40 and the average story of the buildings is 3.85. Here the height of a story is about 4m so the average of the visual point difference is estimated at 15.4m. 2) The type of visual point is divided into the intersection group and the front of the highly used public buildings group. Double intersection types account for about 78.80%(52 spots) which forms a majority part of LCP. 3) The analysis of the difference of visual point level divided by eye level and that of the top of the buildings has been proved that there's a sharp difference resulted from t-test at 1 % significant level. The significant difference of elevation from height difference(l5.93m), however, has not been shown. 4) From the result of T-test about visual quantity by the elements of a view from a different visual point level, the visual quantity of mountain(VQM), sky(VQS), ground(VQG) is significant at about 1% each and that of building(VQB) is at about 5%. The difference in visual quantity of a mountain by the visual point level is at about 4% which can meet a marginal level of LCP necessary for evaluation of mountainscape.

Researches about micro technology travel lively in these days. Such many researches are concentrated in the field of materials and a process field. But properties of micro materials should be known to give results of research developed into still more. In these various material properties, mechanical property such as tensile strength, elastic modulus, etc is the basic property. To measure mechanical properties in micro or nano scale, actuating must be very precise. PZT is a famous actuator which becomes a lot of use to measure very precise mechanical properties in micro research field. But PZT has a nonlinearity which is called as hysteresis. Not precision result is caused because of this hysteresis property in PZT actuator. Therefore feedback control method is used in many researches to prevent this hysteresis of PZT actuator. Feedback control method produce a good result in processing view, but cause a loss in a resolution view. In this paper, hysteresis is compensated by open loop control method. Hysteresis property is modeled in Mathematical function and compensated control input is constructed using inverse function of original data. Reliability of this control method can be confirmed by testing nickel thin film that is used in MEMS material broadly.

This study selects 45 housing complexes in Munheung, Ilgok and Sangmu districts of housing side development zones of Gwangju Metropolitan City and conducts the experiment the visual characteristics of these housing complexes through visual-perceptive information with their residents. As a result of experiment for the evaluation and structurization by visual-perceptive information of view image, there were affirmative evaluations in the whole experimental subjects except variables as 'innovative' and 'new' According to cluster types, while simple reiterative types showed affirmative responses except such items as 'dull', 'common' and 'uniform'. Variational types were affirmative in the whole items. It extracted four evaluation factors including variety, stability, harmony and symbolism. From the above research, it is understood that since the current housing site development has been made after developing housing site by public agencies and sold them to construction companies, housing complexes of different types were built within the same district. Therefore, it cannot be connected to the view of the whole district even if it considered view in planning housing complex. then when future housing side development or housing complex are planned, it is required that view guideline in the dimension of the district should be prepared and housing site development district or housing complex must be able to contribute to urban view by introducing master architect system.

최근 다양한 도시문제로 세계적으로 국가와 기업에서 스마트시티 개념을 도입한 문제 해결 연구가 진행 중이다. 스마트시티는 도시의 ICT를 융합하고 도시의 모든 구성요소를 네트워크로 연결하여 데이터를 수집·전달하며, 다양한 IoT 제품이나 서비스로 구성된 공급망으로 이뤄져 있다. 스마트시티의 여러 사이버 보안 위협 및 공급망(Supply-Chain) 위협 증가는 불가피하며, 이에 대응하기 위해 공급망 보안 정책 등 프레임워크 수립과 더불어, 제로 트러스트(Zero-Trust) 관점에서 데이터 연계에 따른 각 데이터 제공자·서비스 등의 인증과 적절한 접속통제가 필요하다. 이를 위해 국내에서도 스마트시티 보안 위협을 위한 스마트시티 보안모델이 개발되었으나, 공급망 보안과 제로 트러스트와 관련된 보안 요구사항은 부족한 실정이다. 본 논문에서는 해외 스마트시티 보안 동향을 살펴보고, 정보보호 및 개인정보보호 관리체계(ISMS-P)와 국제표준으로 등록된 ICT 공급망 보안에 대한 보안 요구사항을 비롯해, Zero-Trust 관련 기술을 국내 스마트시티 보안모델에 적용하기 위한 보안 요구사항을 제시하고자 한다.
