수질개선을 위한 장기연구 사업(G-7 Project)이 환경처 주관으로 시작되었다. 이 연구사업의 하나인 수질 정보 시스템 개발은 2개의 국립연구소와 대학, 그리고 관련 회사들의 합작으로 추진되고 있다. 이 연구는 통합적 수질관리를 위한 컴퓨터 시스템(ISWQM : Integrated System of Water Quality Management)의 개발을 목표로 하고 있다. 이 ISWQM은 4개의 주된 구성요소 - GIS 데이타베이스, 두개의 인공지능 기법을 바탕으로 한 도심지 오염 부하량 산정을 위한 모델들, 그리고 GIS 데이타베이스와 모델이 연계를 위한 컴퓨터 S/W - 들로서 구성되어 있다. 이러한 ISWQM은 주로 장기적 수질 관련 정책입안을 위한 의사 결정에 도움을 주기 위하여 개발이 시작되었다. GIS는 이러한 수질 관리 시스템의 개발에 있어서 필요시 되는 모든 입력 자료의 공간 데이타베이스 구성에 사용되었으며, GUI(Graphic User Interface)를 통한 위의 4개의 구성요소들을 연계시켜 효율적 SI(System Integration)을 이룩하는데 사용되었다.

Indoor air quality has attracted great attention in recent years and thus the importance of managing finishing materials in terms of pollutant source control is being emphasized. Managing the finishing material at the design stage maximizes the efficiency of IAQ control at the following construction stage. However, there are insufficient investigations on the application of a specific finishing material management process, a database management system or a finishing material management process network. As a result, the main purposes of this study comprise comprehensive evaluation of IAQ performance from the selected finishing materials and auxiliary materials, application of the material management system basing on the types and characteristics of toxic substances generated from the indoor finishing materials, investigation of IAQ evaluation standard, and the overall IAQ evaluation method for the design parts. The result of this study will be the basic data to construct DBMS for management of finishing materials with respect to IAQ.

In automotive industries, reusability of product information is increasing through database construction of previous product data. The product data is stored by data quality management in product information systems. For naval ships, have the functional similarity by the ships of the same classification and class, that are built by series. Information of hull structures as well as embarked equipments are similar. So it would be effective to use database systems that are considered product information quality of previous ships in design and production processes. In this paper we discuss product information quality in database construction of naval ship product models. For this, we propose a basic concept and reference model for data quality verification. Based on this concept, A verification guideline is defined and it is applied for the case study of the digital naval ship which was built to the naval ship product model.

This study was carried out as the Anyang creek water quality management using Geographic Information System (GIS) is the purpose of this pilot project to apply a GIS to environmental management field. Analysis of water quality data has been investigated using GIS with modeling of water quality management for the Anyang creek. The results of this study are summarized as follows: 1. The concentration of Mercury in sediment was increased rapidly nearby A26(Nightsoil Treatment Plant) and maximum was showed at A18 (Imgok bridge). Cadmium was increased rapidly at A35(Chulsan bridge). 2. River water quality management using visible computer system as GIS is effective to make decision for water quality management plan and database of environmental factors should be completed before applying GIS. 3. When water pollution accident is occurred in the river water system, pollutant source can be traced and analysed systematically using GIS to manage pollutants discharged into the river water system.

Advances in computer and sensor technology have made it possible to obtain superlarge manufacturing process data in real time, letting us extract meaningful information from these superlarge data sets. We propose a systematic data analysis procedure which field engineers can apply easily to manufacture quality products. The procedure consists of data cleaning and data analysis stages. Data cleaning stage is to construct a database suitable for statistical analysis from the original superlarge manufacturing process data. In the data analysis stage, we suggest a graphical easy-to-implement approach to extract practical information from the cleaned database. This study will help manufacturing companies to achieve six sigma quality.

In EMS(environmental management system), environmental documents are very important elements to achieve ISO 14000 series certification. A organization or company which hope to acquire the certification must prescribe daily operation procedure and document them properly. Also these documents must be updated in new version. Especially, environment manual, describing EMS factors and correlation between them, is a basic document system. Therefore, a proper manual management tool help a organization or company to reduce the efforts to establish and to revise documents. So, in this paper we will present environment manual management system using database and a, pp.ication computer program.

As the significance of quality in the sense of customer satisfaction is growing, the management of quality becomes one of the main interests in the manufacturing systems research. This paper presents the concept of quality-driven CIM(Computer Integrated Manufacturing) system which is composed of a business process domain and a quality domain. In the business process domain, business functions are integrated by conventional design and manufacturing databases on the one hand, and an integrated quality system is interlinked to them via several quality modules on the other hand. Quality information model connects the business process domain with the quality domain where various types of quality data are stored in the form of quality database. This framework helps a manufacturing enterprise to implement the quality-driven CIM system to achieve its final objective "customer satisfaction".ion".uot;.

Environmental Product Life Cycle Management is an activity for defining and describing the product, process of activity environmentally. The activity involves the full life cycle stages of the product; evaluating environmental releases at each stage, determining the aggregate and specific impacts of the releases, developing opportunities to effect environmental improvements. This paper presents a methodological approach for database modeling to build Product Life Cycle Management system and show a set of database modeling. Additionally, a key issue for database is the quality of the provided information.
