The purpose of this case study is to reduce the flaw and reconstruction occur at the level of construction by determining the propriety of estimate and error on a drawing and specification at working design level through case studies of BIM application at the level of design review. As a preliminary to apply BIM technology, it is needed to review the drawing, and then it is required to define BIM range by selecting the section in which construction error occurs frequently except for the type of part that is constructed repeatedly. At the execution level, the drawing is reviewed vertically, horizontally and spatially by proceeding structure and finish modeling on the defined BIM range, and also the propriety of estimate and error on the drawing and specification are examined. We aim to raise the completion rate, improve quality of construction, reduce the cost for construction and shorten period of construction by preparing for the error on the drawing and specification in advance through this review procedures.

The primary purpose of this study is to develop an automation tool capable of converting the specification of structured analysis into that of structured design. Structured Analysis and Structured Design Language (SASDL) is a computer-aided description language based on ERA model and particulariged by ISLDM/SEM. The automation tool utilizes the specifications of data flow diagram described in SASDL to produce their corresponding SASDL specification of structure chart. The main idea behind the automatic conversion process is to categorize the bubbles in data flow diagram and to determine the positions of the bubbles in structure chart according to their categories and the relative locations in data flow diagram. To make the problem into manageable size, the whole system is broken down into separate parts called activity units. A great deal of manual jobs, such as checking processes leveling, checking data derivation of processes, deriving structure chart from data flow diagram, checking any inconsistency between data flow diagram and structure chart and so forth, can be automated by using SASDL and conversion tool. The specification of structure chart derived by conversion tool may be used in an initial step of design to be refined by SASDL users.

e-book is digital contents using IT technology instead of paper. It is carried in Internet and displayed wish Viewer of PC, PDA or terminal. The Open eBook specification is to provide a specification for representing the content of electronic books to these viewers. The specification is based on HTML and XML, the same core languages that define the World Wide Web, and is designed to allow publishers and authors to deliver their material in a single format. In this paper, we design and implement the viewer that can support OEB(Open eBook) standard. Viewer is composed parser part and display part. In audition, we add some functions - the book shelf, the bookmark and the dictionary - for convenience of readers.

In this thesis, a decomposed LQG/LTR controller is designed for an undersea vehicle. The modellig error which results from decomposition of the original model is considered to the design specification for maintaining the robust stability. The LQG/LTR controller designed with new specification is simulated.

There exists no precedented case of quantity take-off, using parametric modeling, from BIM-based irregular structures. Civil 3D provides earthwork quantity take-off based on surface modeling. Generally, designers should enter data into the specification additionally after extracting quantity estimation from earthwork modeling design. The objective of this report is to suggest the method from quantity take-off to specification of BIM-based earthwork quantities. We intend to investigate earthwork take-off method by Civil3D and explain why parametric information extraction is required for quantity estimation and specification and how information of earthwork quantity based on solid and surface modeling is connected to open quantity take-off module. It is highly expected that this suggestion would be the practical methodology of earthwork quantity take-off and specification in the field of civil engineering.

The purpose of this study is to introduce design practice for transverse reinforcement in piles where the top of the pile is free-standing above the ground in accordance with AASHTO LRFD Design Specification. Based on the relevant requirements, the amount and spacing of transverse spiral reinforcement is given for the two different pile types, namely piles with pile cap and pile bents. In addition, a recommended design procedure is introduced depending on the predicted behaviour of the piles from the analysis.

In this paper, a magnetic circuit of plastic magnet roller for laser printer is presented. The magnetization direction of plastic magnet is decided by the flux distribution of injection mold during the manufacturing process. The injection mold is designed and analysed to fit the design specification. The experiment showed that the flux distribution of a magnet is good agreement of the given specification.

교육평가에서 이원분류표는 B.S.Bloom이 제안한 것으로서 학생들을 위한 수업목표를 확인하고 결정하는데 유용하여 학교 현장에서 평가를 위한 기준으로 널리 사용되고 있다. 그런데, 교과 내용이나 각 학교의 교육적 환경이 다르기 때문에 여러 형식의 이원분류표가 사용되고 있다. XML(extensible markup language) 문서에서는 문서의 구조, 내용, 그리고 외양을 나타내는 프리젠테이션이 각각 분리되어 있어서 체계적인 문서 구조와 변형된 여러 양식을 요하는 이원분류표의 작성에 적합하다. 본 논문에서는 이원분류표를 위한 DTD(data type definition)를 설계하였다. 또한, 이원분류표 XML 문서 및 프리젠테이션을 위한 XSL(extensible stylesheet language)의 예시와 활용 방안을 제시하였다. 제안된 DTD는 교육 평가와 관련된 다양한 응용에 유용하게 쓰일 수 있을 것으로 기대된다.
