This paper is concerned with a computer-aided supporting system to a systematic check of mechanical drawings. The problems treated in this paper are limited to the checking of the omissions and mis-writings of dimensioning in the mechanical drawings made by a CAD system. A drawing check system has been made up on a personal computer with Basic and Pascal. The feasibility of the proposed drawing check system is confirmed for omissions and mis-writings of dimensioning in mechanical drawings.

Since a great number of 2D engineering drawings are being used in industry and at the same time 3D CAD becomes popular in recent years, we need to reconstruct 3D CAD models from 2D legacy drawings. In this thesis, a combination of a feature recognition method and an expert system is suggested for the 3D solid model reconstruction. Modeling primitives of 3D CAD systems are recognized and constructed by using the pattern matching technique of the features modeling. Additional information for the 3D model reconstruction can be generated by extracting symbols or text entities which are related to form entities. For complex and indefinite cases which cannot be solved by the process of feature recognition, an expert system with a rule base has been used for decision-making. A 3D reconstruction system which recognizes 2D DXF drawing files has been implemented where models composed with protrusions, holes, and cutouts can be handled.

This study was analyzed for the relationship between the self-differentiation of the university students and Kinetic Family Drawings that was responded their mental aspect. Results of this study were following. First, the level of self-differentiation by sex, age, region and grade was significantly different. Second, Kinetic Family Drawings respondent characteristics by their sex, age, region, grade and sibling order was significantly different. Third, in the relationship between the self-differentiation of the university students and Kinetic Family Braving respondent characteristics, when the group had less conflict and more interaction among family members, they could separate their subjective and objective tension and they could attach to their parents. In the case that crisis was occurred in their family, they had less possibility to represent dysfunctional communication style or regressive behaviors.

The CAD system for design and drawing of limit gauges was constructed and developed. This system was made by Visual Basic program. Using this system, drawings together with concerned data for the manufacturing of limit gauges are generated on the screen, file and printer. The data base was constructed by referring handbooks, textbooks, relevant standards and regulations. This system was proved a powerful tool for design and drawing of limit gauges by actual applications. The output drawings from this system are in good agreement with the drawings and data of the concerned standards and regulations.

In this thesis, a computerized retrieval system was designed for architectural drawings to provide a faster and more efficient access to information on drawings in architectural design offices. The programs were written in COBOL 5, and operated on the CYBER 170-825 computer at the Yonsei University Computer Center.

As part of effort to reduce the process time from design to manufacture and delivery, the concept of CE(concurrent engineering) has been applied to design process. In this research, the drawing information management system (DIMS) was developed based on CE. The system can distribute electronic documents of drawing or work instruction parallel to all reviewers simultaneously and collect their annotations through network. Mark-up functions are used for annotations on the electronic documents. DIMS is a system which integrates drawing management, engineering BOM, CAD and raster drawings, etc. In this system, a SUN workstation is interfaced with PCs by LAN. CIMCAD-2D, Image Hunter, and ORACLE RDBMS are used for CAD drawings, raster drawings, and drawing information management, respectively. As an integration tool for all the information, LINKAGE is adopted.

The purpose of this study was to investigate middle school students' perceptions about global environmental problems using drawings. The study was involved the collection of drawing data from 112 ninth grade students from a middle school in Daegu Metropolitan City. The environment task was administrated to students drew a drawing of an global environmental problems and explained their drawing in their own words. Also, students was asked to write what he or she can do to solve global environmental problems. The results are as follows: First, air pollution is the most important global environmental problem, followed by water pollution, global warming, sea level rise, deforestation, waste, loss of biodiversity, and so on. Second, the students' drawings were characterized into two aspects: One is a macroscopic viewpoint and the other is everyday viewpoint. Third, the students' practical action plan to do solve global environmental problems were walk, public traffic, do not throw trash, plant trees, etc. Educators should take into account the perceptions of global environmental problems and teaching-learning strategies to enhance students' understanding of global environment.

For the implementation of CE(Concurrent Engineering), the TDMS(Technical Document Management System) which integrates design and manufacuring information, is required. In this paper a drawing information management system, one of the essential modules for the TDMS has been developed. The system is operated in SUN SPARC II workstations. A CAD software called CIMCAD-2D is used for the storage and management of drawings. Relational DBMS ORACLE is used for the development of information data bases concerned with drawings. As an integration tool, the multi-media software called LINKAGE is used. Various functions for drawings and concerned information have been developed with the internal language CIMSHELL and SQL $^*PLUS$.

GDS (Grating automatic Drawing System), which is automatic design system of metal products called grating, is a system that produces various detailed drawings on the basis of information within a Plan Drawing that represents layout of the gratings such as locations, shapes, directions, etc However, automatically produced drawings by GDS do not fully satisfy the standard of the general dimension marking method used among the layout designers. The lack of this standard quality mainly results from the fact that overlapping among dimension markings appears frequently. To solve the overlapping problem we applied the rule-based expert system. The rules for the expert system are designed based on the expertise of skilled layout designers within the grating production lines.
