Recently reservoir is polluted by concentrative development of urbanization. Accordingly, the prediction of water quality has import meaning for protecting of water quality pollution. This study was carried out to predict water quality of Gyung Cheon reservoir by WASP5. We have established an integrated system on the basis of web, which predicts the future quality of water through water quality model, WASP5 based on information of water environment in a reservoir for agriculture, uniting expert system which supports the determination to set up measures for improving the quality of water to cope with the result.

In recent years, customers and power supplies are interested in power quality. Demands of customers are change from standard quality of distribution power system to various high quality of distribution power system. so, it is necessary to apply power quality compensator. in our project, we develop the UPQC(Unfied Power Quality Compensator of 45kVA which compensates power factor and voltage sag, interruption. it is very frequently occurred power quality problems. As a series and shunt compensator, UPQC consists of two inverters with common dc link capacitor bank. It compensates the current quality in the shunt part and the voltage quality in the series part. In this paper, we present simulation and test result of developed UPQC system. Test for UPQC are performed at voltage sag, flickers and non-linear load conditions. For voltage sag and ficker generation, we use RTDS(Real Time Digital Simulator) and power amplifier system.

In this paper we will concentrate on the Quality Control Policy which should be enforced as a part of the Total Quality Control considers the global concepts, the establishment Procedures, and the evolution and operation of Quality control policy to achieve effectively it. For enforcement of the Qualify control policy shall be focused for considerations : (1) suggestion of the optimum control policy (2) suggestion of a comprehensive plan and promoting method quality control (3) suggestion of matters that need special consideration at the time of decision of a comprehensive management of control policy thereof. (4) A comprehensive Proposal (5) suggestion of a plan for progress of the Quality control system and the supplementary plan In the future, accordingly, establishment d its own policy control level is desirably more reasonable, and the Total Quality Control System that employes the control efficiency of periodical and systematic and rationalization and radical reform of the enterprise management problem as the restrictive conditions must be applied for quality control system.

Most of fruit quality classification has been done by time consuming, inaccurate and intensive manual labor. This study proposed an automated fruit grading system based on appearances and internal flavors. In this study, image processing technique and a weight checker were used to measure the value of appearance features and the near infrared spectroscopy analysis method was used to estimate the value of internal flavors. Additionally, I suggested 8x8x5x5 ANN based fruit quality classifier model to grade fruits quality. The proposed automated fruit quality classification system is expected to be very beneficial for many farms where heavy manual labor is usually needed for fruit quality classification.

It is very important for performance of information system that we make an effort to raise user's satisfaction by continuously grasping user's requirement by evaluation of PMIS based on ASP service quality and reflecting this to information system. However, It is lack that developments of suitable evaluation index of PMIS based on ASP service quality. Hereupon, In this study, we propose the evaluation indicators. First, The evaluation area is classified by form the foundation of D & M IS Success Model (2003); system quality, information quality, service quality. Second, The detail evaluation item which include considerations which are gotten through investigation of the construction industry and PMIS based on ASP is grouping by form the foundation SERVQUAL which is a service quality evaluation tool proposed PZB(1988). It is suitable to evaluate PMIS based on ASP service quality in construction industry and able to evaluate various aspects.

The purpose of this study is to implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. Developed WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. The proposed system was developed using Microsoft's .Net technology, ASP.NET and MS-SQL Server 2000. By web-enabling Q-cost management system, the effectiveness of the system management and utilization was realized by easiness of information integration and economical efficiency.

This study was conducted to cultivate a large quantity of high-quality Bonsai through the development of bottom irrigation system. Bonsai placed on the FRP bed were grown very well by bottom irrigation system compared with direct watering and sprinkler system. It was concluded that bottom irrigation system was possible to reduce considerable manual labor and produce mass production of high-quality Bonsai.

Recently, many weapon related quality issues have arisen in the armed forces, such as failures of K-21 Infantry Fighting Vehicles, K-9 self-propelled mounts, and grenade explosion during boot training. Since all of the issues are repetitive phenomena, we examined the defense quality management system and identified the possible solutions for it. Since the government quality assurance agency performs their quality assurance activity using the system evaluation technique, we first reviewed the regulations related to the defense quality management system. Then, we benchmarked some other advanced quality management systems. We suggested two types of defense quality management system, one for small (in terms of the amount of the contract) competitive contracts and the other for large private contracts. For the first one, we adopted the framework of MIL-I-45208 (Inspection System Requirement), while for the second one, we adopted the framework of NATO AQAP 2310 (Quality Management System Requirements for Aviation, Space and Defense Suppliers).

ISO 9000 is an efficient quality system for the customer's confidence and satisfaction. Of late years, the revised edition of ISO 9000 quality management system may give lots of positive business values to companies running ISO 9000 system. Despite its tremendous popularity, there is some criticism against the effect and performance of ISO 9000 certification. This research explores the performances and effects of ISO 9000 quality system in small & medium size industrial companies. For this research, 202 companies certified by ISO 9000 standard and 67 companies not certified as contrast group were selected. The related data were collected by web-poll survey. The major analyses are focused on the effect and performance of the ISO 9000 certification, and we established various hypotheses to verify the effect and performance of quality system. Results of statistical analyses show that total performance of quality system is significantly different between certified companies and not certified.
