A digital twin is a technology that creates a virtual world identical to the real world. Problems in the real world can be identified through various simulations, so it is a trend to be applied in various industries. In order to apply the digital twin, it is necessary to analyze the drawings in which the structure of the real world to be made identical is designed. Although the technology for analyzing drawings is being studied, it is difficult to apply them because the rules or standards for drawing drawings are different for each author. Therefore, in this paper, we implement a system that analyzes and classifies the vertex detail, one of the drawings, using artificial intelligence. Through this, we intend to confirm the possibility of analyzing and classifying drawings through artificial intelligence and introduce future research directions.

The current cadastral business is being operated by conversion to a digital cadastral management system through computerized registers (land register and forest land register) and maps (cadastral map and forest cadastral map). Digital surveying methods, such as GPS surveying and electronic plane table surveying, are also used for cadastral surveying. At present, fees for cadastral surveying are calculated based on a standard pursuant to the Construction Standard Production Unit System and an announcement by the Ministry of Land, Infrastructure, and Transportation. In many cases, however, the cadastral surveying fee system announced at present fail to apply the digitalized environment depending on the item. This study sought to analyze the cadastral surveying fee system that requires improvement in the rapidly changing digital cadastral management environment, and to prepare a basis to establish a cadastral surveying fee system suitable to the digital environment by suggesting an improvement method for such system. As a result of the study, the following suggestions were made: a method of changing to terms suitable to the digital environment based on the current status analysis; preparation of a new estimation system regarding new estimation items; and re-survey of an estimation system of cadastral confirmation survey and preparation of an estimation system.

본 연구에서는 지적도면 정보에 대하여 불법 복제와 유통의 방지는 물론 유통 후에도 유통 경로를 파악하여 차단할 수 있는 디지털 워터마킹 기술을 개발하여 보고자 하였다. 연구성과로는 지적도면은 일반 지형도와 달리 워터마크의 삽입 및 검출 과정에서 왜곡이 없어야 하고, 또한 토지이동시 발생할 수 있는 다양한 공격에서 강인성을 가져야한다는 특성을 고려하여 주파수 영역에서의 워터마킹 삽입 및 검출 시스템을 개발하였다. 향후 연구에서는 구현된 워터마킹 시스템의 성능을 평가하여 보고자 지적도면의 위치정확도 분석에 기초한 왜곡정도를 분석하고, 다양한 토지이동 상황(분할, 합병, 접합, 이동, 회전 등)에 대한 강인성 및 검출율 등을 실험하고자 한다.

현재 많은 분야에서 사용하고 있는 2D 3D CAD(Computer-Aided Design)는 기하학적 요소들의 그래픽 구현에 주로 활용되어 왔다. CAD를 통해 이전의 수작업 도면작성에서 디지털 도면작성으로 설계 방법의 변화가 촉진됨으로써 설계오류를 크게 줄이는 한편 설계변경에도 많은 편리함을 가져 왔다. 지금 건축 설계의 패러다임은 단순한 기하학적 드로잉에서 '정보'를 만나, 건축의 전 과정뿐 아니라 사후 유지관리에 대한 각종 데이터까지 처리할 수 있는 BIM으로 발전되고 있다. 본지는 컴퓨터 지원 설계의 변천 과정과 건설시장의 새로운 프로세스로 부각되고 있는 BIM의 현황 및 설비업계와의 접목 가능성, 향후 전망 등에 대해 알아본다.

Many digital logic circuit simulators have been developed for the education on the experiments of digital logic circuits for college or high school students. But the existing simulators have some constraints on the number of inputs of gate, on the display of gate and wire states, and on the number of logic diagrams to be simulated. 1n this paper, we propose a simulator XSIM(eXpandable digital logic circuit SIMulator) which mitigates the constraints and allows multiple diagrams for large scale logics. It is expected that the multiple diagrams on large logics are helpful for team-teaching in school.

The purpose of this study is is to organize the site-plan types of common design's Goon office buildings in Japanese colonial period based on the main building's shape and main & attached building connection way and to investigate all the types' addition & remodeling ways. The study used literature research method, analysing the digital images, the annotation of the images, official documents between the Japanese government-general of Korea and To, and articles of newspapers or journals. The site-plans are sorted 5 types and subdivided 13 as their addition & remodelling ways. The initial shapes of site-plan were changed to apply every Goon's site circumstances, The main buildings were always in the center ahead and attached buildings behind or next to them in any cases of new construction, addition or remodeling. The buildings of the common design's were constructed until early 1930s and it means that their architectural level was lower than Pu office buildings, although both had same administrational level.

Government agencies and companies are establishing and promoting digital transformation strategies in various industrial fields, and are leading the era of the 4th industrial revolution through successful technological innovation. In this time of change, we can see many stories of global companies Nike and Starbucks as successful examples of digital transformation. These two companies are showing successful results through digital transformation. Domestic companies are also conducting digital innovation based on mobile, cloud, IoT, artificial intelligence, and AR/VR technologies, and are establishing RPA (Robotic Process Automation) processes for high efficiency and high productivity. In this paper, we introduce the 3D digital twin space construction automation process technique using data from the entire construction cycle of design, construction, and maintenance of the construction industry, and look into the digital transformation strategy of the construction industry in the future.

The restoration of archaeological data was carried out using photographs and drawings left as past records. It can be divided into ruins and artifacts. The restoration of the ruins was performed by modeling the individual parts and parts left by the photographs, aligning them and synthesizing them, and reconstructing them three-dimensionally as one object. Restoration of artifacts was performed on both photographs and drawings. After the modeling work is prioritized through the photographs, there is a method of restoring the original image by modifying the texture image of the damaged part of the modeled artifact, or restoring the original image by modeling and synthesizing the deleted part in the artifact. The restoration of the artifacts through the drawings was carried out by three - dimensional modeling and reconstruction through real mapping of images. The reconstructed archaeological data can be used in various directions. In particular, it is possible to verify and compare the results of the numerical analysis and interpretation of the past 2D data, and to provide a more accurate analysis plan in the future.
