고고자료의 복원은 과거 기록물로 남겨진 사진과 도면자료를 이용하여 진행하였다. 크게 유구와 유물로 구분하여 살펴보았다. 유구에 대한 복원은 사진으로 남겨진 개개 부위 및 부분을 모델링하고, 이들을 정렬 및 합성하여 하나의 객체로 3차원 복원하였다. 유물에 대한 복원은 사진을 통한 모델링 작업을 우선한 후, 모델링된 유물의 파손 부위에 대한 텍스쳐 이미지를 수정하여 원상 복원하거나, 유물 내 결실부위에 대한 모델링 제작과 합성을 통한 원상을 복원하는 방식이 있다. 도면을 통한 복원은 3차원 모델링 제작과 함께 이미지의 실사맵핑을 통한 복원을 진행하였다. 이렇게 복원된 고고자료는 과거 2D자료를 통한 수치 분석과 해석의 연구성과를 검증하고 비교를 진행할 수 있으며, 추후 더욱 정확한 분석 방안을 제시할 수 있다.

최근 활발한 수치지도의 제작과 함께 수치지도 수정/갱신의 필요성도 증대되어가고 있다. 수치지도를 수정/갱신하는 방법에는 사진측량, 지상측량, 인공위성의 활용 등 많은 방법이 이용되고 있으나, 작업의 과정에 많은 시간이 소요되고, 소규모 지역적인 부분의 갱신에는 경제적, 시간적인 문제로 적용하는데에 제한적인 요소들이 존재한다. 따라서, 본 연구에서는 공사의 준공시에 작성되는 준공측량도면을 이용하여 수치지도를 수정/갱신하는 방법을 제시하고 이에 대한 정확도를 분석하여, 경제적인 수치지도의 수정/갱신방법을 제시 하였다. 본 연구의 결과, 1/1,000 수치지도를 수정/갱신하기 위하여 1/1,200 준공측량도면을 이용한 결과, 국가 수치지도 제작 정확도에 준하는 수치지도의 수정/갱신이 가능하였다. 또한, 수치지도의 갱신을 위하여서는 전산화된 파일의 제공이 필요하며, 보다 정확한 준공측량도면의 작성을 위하여 지역기준점 개념의 도시보조 기준점의 도입이 적극적으로 검토되어야 할 것으로 조사되었다. 이를 뒷받침하기 위하여 준공단계에서 측량을 실시하여 준공측량도면을 작성할 수 있는 법률적인 지원이 있어야 할 것이다.

Karmiloff-Smith was first to propose the 'Representational Redescription model'. It describes a process through which children elaborate their knowledge from the unconscious and implicit levels to the conscious and explicit levels. The model also assumes that children in perfectly explicit levels are able to express their own representation of knowledge verbally. This study was conducted to investigate Karmiloff-Smith's Representational Redescription(RR) model(1990, 1992, 1999) within the drawing domain. Additionally, how verbalization training influences children's development of representational redescription in drawing were also examined. First, 331 children (4- to 6-year-olds and an older comparison group of 7- to 9-year-olds) were asked to create six drawings of both familiar and novel topics. From these drawings, children were measured for procedural rigidity and developmental differences. Thereafter 80 5-year-olds children who were not able to manipulate their drawings with flexibility were selected. They were divided into an experimental group and two control groups. A group of verbalization training was given a session using 5 tasks. Compared to the control groups, children who practiced verbalization in the training group showed more advanced levels of representation than their previous levels in the pretest. The results were interpreted as meaning that verbalization is likely to facilitate children's reorganization of implicit knowledge within the drawing domain and to transfer this toward explicit forms. Further research needs to pay more attention to the educational applications of learning processes based on representational redescription.

본 논문에서는 선박 건조 과정에서 전기/전장 시스템의 생산을 담당하게 될 신규 입사자의 훈련에 3D 기반의 학습자료를 적용하는 방법에 대하여 연구하였다. 대부분의 신규 채용자나 전직자들은 설치도면을 해석하는 능력이 부족하여 첫 업무를 수행할 때 큰 어려움을 겪는다. 이런 현상은 도면에 애매모호한 기호들이 너무 많아서 전기 장비 및 케이블 설치에 필요한 부품들의 특성을 명확하게 나타내지 못하는데서 기인한다. 이런 문제를 해결하기 위해, 본 연구는 선박 내 전기/전장 시스템의 생산에 요구되는 주요 부품들의 3D모델을 활용하여 신규 입사자들의 도면 해석 능력을 향상시킬 수 있는 새로운 교육 훈련 방법을 제안하였다.

In the representation of buildings with continuous changes in the curved shape of the surface, countless plans or sections are required, or none of the traditional drawings can explain the geometry of it. In other words, in no case can an ordinary drawing achieve the efficient and clear communication capability which is inherent function of the drawings. As a result, the current architects are introducing their own way of drawing technique which is developed in accordance with a specific curved shape, construction method or company resources, but this is not what can be applied to other cases because it has not been ever shared or agreed in the industry. In this process, the drawing or construction of curved building has been recognized as the exclusive property of a specific expert, or the design and construction without the in-depth understanding of the technology have resulted in the appearance of poor buildings. Therefore, this study aims to present an elements and method that can convey shape information more effectively and clearly in the drawing representation of non-linear buildings and, thus, contributes to lowering the barriers to entry into the field by providing the information to be easily applied to related projects. In order to attain this goal, the drawings of recently completed projects of free form building are analyzed to reveal the method used to effectively express the shape information of the building and to derive new drawing elements that have not been applied to the existing drawings.

Shop drawing tasks conducted after finishing coordinated or engineering design have great influences on the quality and cost of a project. However, despite the development of commercial BIM applications, shop drawings have mainly produced manually in certain engineering fields. Incorrect shop drawings with human errors have occurred various problems such as cost overrun, time delay and reworks. An automated shop drawing publishing from BIM is expected to resolve these problems. Despite attempts for automate shop drawing production, the field of mechanical, electrical and plumbing (MEP) is yet regarded challenging due to complexity of components and connection. In this research, we develop a process for automated producing 3D MEP shop drawings in BIM environment as following steps: to analyze conventional MEP shop drawing process, to identify detailed process that can be automated, to classify existing MEP objects and assign codes usable in BIM, and to develop an application. The validation of automated process is conducted against 10 clean room projects in which MEP is more complex and its cost is higher than other projects in terms of productivity and workers' satisfaction. Results show that the number of manpower for shop drawing is reduced by 30%, and the working time is shortened by 31%. Personal opinions of involved practitioners is interpreted as positive as the average rate of agrement on practicability, easy-to-use and necessary retouch tasks is around 66%.

Even though Gothic architecture, one of the most technologically complex sophisticated structural systems, has been interpreted by art and architectural historians since the nineteenth century, we still cannot entirely comprehend either the medieval builder's constructional technique and structural knowledge or the meaning of Gothic architectural elements. The major reason is that contemporaneous written documentation concerning design methods and constructional techniques of medieval architecture is lacking. In 1955, the Bibliotheque Nationale in Paris exhibited the sketchbook of the thirteenth century architect Villard do Honnecourt. After the exhibition, analysis on the architectural drawings of Villard's sketchbook had reported widely. Most of analysis on Villard, however, has been on his drawing and artistic style, and there has been very little published analysis of his profession and question on the author of the sketchbook. Thus, the purpose of this study is to investigate the characteristics of the sketchbook and identify the artist who drew it. The sketchbook poses a number of unsolved questions. There is no doubt that several hands have contributed some drawing with appropriate captions, particularly in the section devoted to the application of practical geometry to problems of masonry and carpentry. Scholars have assumed and revealed that it was not made by only one person, and it dealt too many different fields and styles. Through this study, the sketchbook drawings consist of five different styles and person (original painter, master1, master2, master3, and the last owner), and they, not Villard, just redrew the original drawings and bound the sketchbook. Therefore, Villard de Honnecourt was just a mentor of the sketchbook and he did not participate any writing and drawing in the sketchbook.

Currently, all design information of a hull structure is being first defined on 2D drawings not 3D CAD model at the initial ship design stage and then transferred to following design stages through the 2D drawings. This is caused by the past design practice, limitation on time, and lack of hull structural CAD systems supporting the initial design stage. As a result, the following design tasks such as the process planning and scheduling are being manually performed using the 2D drawings. For solving this problem, a data structure supporting the initial design stage is proposed and a prototype system is developed based on the data structure. The applicability of the system is demonstrated by applying it to various examples. The results show that the system can be effectively used for generating the 3D CAD model of the hull structure at the initial design stage.
