  • The ISO 9000 Follow-up Management Practices (FMP) as an integrated area including training, QM systems, management commitment, customer focus, communication and related issues are examined. A sample of 191 small and medium-sized firms data from mail survey is analyzed by the SPSSWIN. A model of FMP including three factors (Systems, Training, and Customer Focus) is introduced. In this paper, a focus is laid on the comparison between ISO 9000:1994 vs. ISO 9000:2000 or 05 9000 certificates and between groups classified by the time length after certification, and on regression relationships between FMP level and business performance. The result shows that the difference of FMP level is significant between two versions and between groups. Quality level and system satisfaction are influenced significantly by the three factors.

  • BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

  • As the IT service environment grows, it is critical in terms of IT service quality to minimize the occurrence of failures due to changes in applications and to diagnose and recover in a short period of time how failure will affect the business. Thus, the Defense Acquisition Program Administration (DAPA) has been building and operating ITSMs to implement IT service management in a leading manner. Information Technology Service Management (ITSM) is divided into events, obstacles, changes, versions and setup management to ensure flexibility and stability in service delivery. It is also operated separately from service level, availability, capacity, financial and IT service continuity management to ensure service quality and cost efficiency. Based on ITSM military service history, this study looks at the impact of quality of service on value, satisfaction, and trust. The results of the analysis are highly valuable for future ITSM implementation and operation.

  • This paper describes the design and implementation of a CAD object management system for the design library in VHDL design environment. For the efficient manipulation of design objects, the library is managed independently of the underlaid CAD system. Management and revision of design objects can be performed by a batch script of server commands or through the user interaction in the X/MOTIF graphic environment. Through the library server, design management tasks can be efficiently performed, such as configuration of design objects, version control, and management of attributes and methods for versions. Experimental results show that the proposed system is a viable tool for the management of design data in VHDL design environment.

  • Recently, a major issue in the research of metadata is the standardization of metadata format. The new extension capability of metadata in the standardization requires some changes - storing and managing dynamic data consistently. In this paper, we define the characteristics of new metadata and propose a concurrency control called Two Version Latch (2VL). 2VL uses a latch and maintains two versions. Maintaining two versions using latch minimizes conflicts between read operation and write operation. The removal of unnecessary lock holding minimizes refresh latency. Therefore, this algorithm presents fast response time and recent data retrieval in read operation execution. As a result of the performance evaluation, the 2VL algorithm is shown to be better than other algorithms in metadata management system.

  • Recently, in the competitive environments, every company recognizes the importance of supply network planning models. However, there are so many problems in correctly applying mathematical model to the real world. Because mathematical modeling packages charge planning managers with understanding the models and responsibility for generating plans, fast and accurate model cannot be generated with ease. In this paper, we design the model management system that helps planning managers flexibly create and modify mathematical models and manage model versions. We implement the system with model base concept.

  • Biclustering is a method to extract subsets of objects and features from a dataset which are characterized in some way. In contrast to traditional clustering algorithms which group objects similar in a whole feature set, biclustering methods find groups of objects which have similar values or patterns in some features. Both in clustering and biclustering, validating how much the result is informative or reliable is a very important task. Whereas validation methods of cluster solutions have been studied actively, there are only few measures to validate bicluster solutions. Furthermore, the existing validation methods of bicluster solutions have some critical problems to be used in general cases. In this paper, we review several well-known validation measures for cluster and bicluster solutions and discuss their limitations. Then, we propose several improved validation indices as modified versions of existing ones.

  • A Mobile computing environment is a new paradigm which provides users with the access to information irrespective of users' location. A transaction scheduling method for the mobile computing environment must be designed so that database consistency is maintained with considering the limited performance of mobile hosts and the narrow bandwidth of a wireless network. The scheduling method using a lock has some problems: the high message overhead between a server and a mobile host for maintaining a lock and the high abort ratio of the mobile transactions owing to violating the serializability when a mobile host uses a cache. So, in this paper, we propose an efficient transaction management method using timestamp to resolve these problems. The proposed method is used in the environment under which a mobile host uses a cache having two versions for each cached data item and a server maintains several versions for each data item. So, even though a mobile transaction is executed during several broadcasting interval, can be committed. As a result, the proposed method can improve the commit ratio of the mobile transactions by maintaining multiversion for each data item and does not require the additional message exchange to schedule transactions by using timestamp.

  • The storehouse for ice was an installation to use the ice during summer season. Even though it shows various versions of styles according to the different periods and regions, it consistently developed through the history with structural characteristics. In this study, first, the management of the icehouse system through the history is examined; second, seven existing icehouses in Korea are investigated in terms of their size, material, history, structure ; and finally, the structural patterns of the ice houses are examined.
