Due to the paradigm shift of the industrial structure in the contemporary china society, the usage of practical function of industrial facilities goes down in this high developing society, so that it falls into some unused spaces. But the unused industrial facilities that including historical, symbolic and cultural meaning has been creating a new cultural space by giving architectural form and function through a variety of application methods for revitalization design. Especially, the facade design which fully expresses the function and meaning of building while properly expressing the cultural situation. It improves the living and cultural conditions of residents while giving the new symbolism of unused industrial facilities through various ways of application methods for revitalization. The unused industrial facilities that was reconstructed into the exhibition space in Beijing and Shanghai, china since 2006 is the object and scope of this study. The purpose of this study is to analyze the methods and characteristics of application methods for revitalization according to each component of the facade design in the idle industrial facility and to expect it to become basic data in the future design plan of unused industrial facilities.

Purpose: To propose improved method for normalization, compare to the de facto international standard which is IESNA TM-21 or conventional normalization methods. Methods: Firstly, we analysed conventional methods and specified the problem of normalization method which is based on first measured data. Secondly, we proposed our approach which is based on the design specification. Lastly, we studied a real degradation data which is conducted for 15,000 hours. Conclusion: Proposed normalization method is better approach because it can reflect real data and design specification, and reduce distortion when analysing degradation data. Also, It is appliable to other long-life reliability items.

In design stage of a plastic injection mold, basic entities of various kinds are introduced under the concept of Group Technology to produce a full drawings of the mold more effectively Most of the entity data should be extracted from the assembly drawing by pattern matching technique. An automated design system is developed using the extracted data of entities and thus shows a good interfaces between the design stage and producing part explosion without any manual conversion procedure under the AutoCAD environment.

Information obtained from DFD(Data Flow Diagram) are very important in system maintenance, because most legacy systems are analyzed using DFD in structured analysis. In our thesis, we design and implement an extractor for design sequence of database tables using DFD. Our extractor gets DFDs as input data, transform them into a directed graph, and extract design sequence of DB tables. We show practicality of our extractor by applying it to a s/w system in operation.

During the past several decades, the Taguchi robust design method has been widely used in various fields successfully. On the other hand, some researchers and practitioners have criticized the method with respect to the way of utilizing orthogonal arrays, the signal-to-noise ratio as a performance measure, data analysis methods, etc., and proposed alternative approaches to robust design. This paper introduces the Taguchi method first, evaluates the validity of the criticisms, and discusses advantages and disadvantages of each alternative. Finally, research issues to be addressed for effective robust design are presented.

A new method for creating a logical data model is proposed. The logical data model developed by the method defines table, primary key, foreign key, and fields. The framework of the logical data model is constructed by modeling the relationships between events and their related entity types. The proposed method consists of a series of objective and quantitative decisions such as maximum cardinality of relationships and functional dependency between the primary key and attributes. Even beginners to database design can use the methology as long as they understand such basic concepts about relational databases as primary key, foreign key, relationship cardinality, parent-child relationship, and functional dependency. The simple and systematic approach minimizes decision errors made by a database designer. In practial database design the method creates a logical data model in Boyce-Codd normal form unless the user of the method makes a critical decision error, which is very unlikely.

Data warehouse(DW) manages all information in a Enterprise and also offers the specific information to users. However, it might be difficult to develope an effective DW system due to varieties in computing facilities, data base, and operating systems. The heterogeneous system environments make it harder to extract data and to provide proper information to usesr in real time. Also commonly occurred is data inconsistency of non-integrated legacy system, which requires an effective and efficient data extraction flow control as well as data cleansing. We design the integrated automatic ETT(Extraction Transformation Transportation) system to control data extraction flow and suggest implementation methodology. Detail analysis and design are given to specify the proposed ETT approach with a real implementation.

An ecconomically competitive automated manufacturing system integrates the various control processes and data used in design, manufacturing, sale and service of products. CIM is a way to achieve such integration through computers and computational techniques in design, planning, and manufacturing. Developing effective CIM architectures is hampered by integration problems. The key to resolving these problems lies in a better understanding of manufacturing function and how it is related to other manufacturing functions. Integration of CIM environment requires coordinated solutions to data management problems for individual application system as well as for exchange of data between these applications. This requires a common framework for data management throughout the CIM environment. This paper discusses the design paradigm as a framework for this purpose. Designing an organizational structure to meet those goals involves 1) analyzing the functions through functional decomposition, 2) developing a data model to coordinate functions. As a result, we propose an object-oriented design methodology for manufacturing information system.

The purpose of this study is to analyse consumer injury and to find current status of industrial consumer injury in the field of consumer product. Also the subject under analysis is to develop a design guidance for the consumer product safety. we used consulting data of Korea Consumer Protection Board, Korea Product Liability Consulting Center and referred to statistic data of Korea National Statistical Office. Consumer injury data of Korea is insufficient comparing with leading industrialized nations. Therefore, we categorized hazard factors based on current injury data in Korea instead of analysing injury data statistically. And we analyse the hazard factors using the analytic hierarchy process in this study. Through the results, we defined the Consumer Injury Index(CII) to develop a design guidance for the consumer product safety.
