The application of CT with basis on 3 dimensional-reconstruction is getting more widely practiced. With the data obtained from cone-beam computed tomography(CBCT), not only the diagnosis of the patient with skeletal abnormality but also the virtual simulation of the orthognathic surgery were performed and its application would be popular in orthodontic field. We reported a case, a 19-year old man who was diagnosed mandibular prognathism and required orthognatic surgery. In this case, the virtual orthognathic surgery was simulated and surgical wafer was fabricated by using CBCT data. That wafer was applied the actual orthognathic surgery. After preoperative orthodontic treatment, we prepared surgery as follows. : (l)Acquisition of 3D image data, (2)Reconstruction of 3-dimensional virtual model, (3)Virtual model surgery, (4)Extraction of stere-olithographic image, (5)Check-up for occlusal interference, (6)Fabrication of surgical stent by stereolithography. Bilateral sagittal split ramus osteotomy was operated and used stereolithographic surgical stent. 1 month later, we superimposed CBCT datas of virtual surgery and that of actual surgery, and then compared the result. CT data's application for othognathic surgery yielded satisfactory outcomes.

불연속 변위해석법 (DDA Method)는 개별요소법의 일종으로 최근에 개발된 새로운 해석법이다. Shi(1998)는 그의 박사학위 논문에서 DDA Method를 최초로 제안하였다. 또한 이 방법에 기초한 전산 프로그램이 개발되었으며 몇 가지 적용 예들이 그의 박사학위 논문 및 여러 가지 학술논문집에 발표되었다. 지난 11년간 (1988 - 1999) 암반공학 분야에서 DDA방법의 개발 및 적용에 많은 발전이 있었다. 본 논문에서는 DDA방법의 기본이론 및 개발현황을 제시하였으며, 지반공학 분야에 있어서의 DDA방법의 적용내용을 정리하였다. The Discontinuous Deformation Analysis (DDA) method is a recently developed technique that can be classified as a DEM method. Shi (1988) first proposed the DDA method in his doctoral thesis; computer programs based on the method have been developed and some applications of the DDA method in rock mechanics have been presented in the doctoral thesis and various publications. During past 11 years (1988 - 1999), considerable progresses have been achieved in developments and applications of the DDA method in the rock mechanics. In this paper the basic theory and developments of the DDA method are presented and applications of DDA method in geotechnical engineering are reviewed.

김용일,양관목,Kim, Yong-Il,Yang, Kwan-Mok 한국교육시설학회 2016 敎育施設 Vol.23 No.6

The objective of this paper is to introduce a curriculum for BIM design and explores characteristic of BIM Design. In order to get our approach, conducted by means of BIM throughout an actual experiment by elementary school from Architectural programming, preliminary design to design development and construction drawing. The experiment states that curriculum for BIM design requires systemically to be made in the architectural education. And also schools integrate BIM teaching early into in their curriculum. Some schools claim that BIM is often perceived as stumbling block student' creativity on account of its instant building elements. But this is not so; it all depends on how BIM is taught in the architectural education. The results state that students in the architectural school today is required to learn design by means of BIM early in the first year. Also more importantly, in order to advance the BIM design, a curriculum for BIM design is required to diversely open class in the architectural education.

김용일,Kim, Yong-Il 한국교육시설학회 2014 敎育施設 Vol.21 No.5

It is evident that the education of architecture is being transformed under the influence of technological, environmental, social, and financial challenges. BIM application for design education is innovative responses that are expected to provide the high ground for the AEC industry. So the purpose of this paper introduces that application of BIM for design education of students is efficiency and effectiveness through an actual experiment by elementary school project. The results by actual experiment elaborate the role of BIM in architectural education and its appropriate place in the curriculum. Also they state that increasingly complex nature of professional world that is reliant on design teams, joint development efforts, and more complex design projects makes obsolete the designer who is trained as solo artist engaging in competitive and individual pursuits.

BIM을 이용한 건축디자인 교육의 실험연구

김용일,양관목,Kim, Yong-Il,Yang, Kwan-Mok 한국교육시설학회 2012 敎育施設 Vol.19 No.5

Results of experiments conducted in university-based design studio suggests that Building information Modeling invites the adoption of a dramatically different design process, traditional design process and BIM-aided design process. Experiment method is used the actual experiment by students. In contrast to traditional design process rooted in successive refinement of abstractions and dependence on tacit knowledge, the studio BIM-aided design process depends on a complete and comprehensive date base and alterative solutions by complete analysis for helping choice of finial result. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The results reflect new ways of teaching and addressing BIM methods and process in the design studio project.

본 논문은 소셜 네트워크상의 내부관계와 외부관계를 반영하여 사용자간의 관계를 사용자 중심으로 계층적 시각화하는 새로운 클라우드 기반의 방법을 제안한다. 본논문의 시각화방법은 상관관계 행렬을 이용하여 사용자의 내부관계를 계산하여 소셜 네트워크상 사용자 중심의 관계 계층을 잘 나타내며, 소셜 네트워크의 외부 관계를 이용하여 사용자의 계층 관계에 접근 노드의 중요도를 반영한다. 제안방법의 사용자들은 소셜 네트워크상의 사용자 노드 관계가 계층적으로 시각화되기 때문에 사용자 관계를 잘 이해할 수 있다. 이외에 제안된 방법은 하둡(hadoop)과 하이프(hive)를 이용하여 분산저장 및 병렬로 계산하며, 계산 결과는 D3를 이용하여 계층적 그래프로 시각화한다. This paper proposes a new visualization method based on cloud technique which uses internal relationship of user correlation and external relation of social network to visualize user relationship hierarchy. The visualization method of this paper can well represent user-focused relationship hierarchy on social networks by a correlation matrix. The importance of a access node reflects into user relationship hierarchy by exploiting external relation of social network. Users of the method can well understand user relationships on account of representing user relationship hierarchy from social networks. In addition, the method use hadoop and hive for distribution storing and parallel processing which the result of calculation visualizes hierarchy graph using D3.
