  • This paper first was focused on investigating the relative effect of each ISO 9001: 2000 certification factors on service quality and customer satisfaction in service industry. The empirical tests was conducted in service industry. The results are as follows. First, it shows that ISO 9001:2000 certification factors except requirements for quality management have a positive effect on service quality significantly. Second, it also indicates that service quality precedes customer satisfaction like other researches reported. Finally, different effects of ISO 9001:2000 certification factors on service quality are observed in the various industries.

  • Amid the rapidly changing constructional business conditions, the volume of BTL business sectors has expanded largely during two or three years. Especially, construction works fur educational facilities of elementary, middle and high schools has been performed by the mid-sized construction companies who are not capable of doing effective and systematic quality management while the requirements of the customers are getting higher and higher. In order to have a flexible deal with the rapidly changing business conditions and also to enhance the quality level, it is the high time to reorganize the effective quality management systeme by doing the overall analysis about the quality defects in construction site. Accordingly through the investigation about the quality defects in the construction sites of domestic educational facilities, this study will focus on what kind of quality defects show. It is aimed at providing the preliminary data for the establishment of quality management fur the construction site of the domestic educational facilities by analysing the investigation results.

  • Consumers are increasingly quality orientated and an understanding of the factors that influence product quality is a prerequisite to the development of programs to produce quality pork to meet market requirements. Pork quality is comprised of many components and is multi-factorial in nature. This review focuses on genetic and environmental influences on muscle color, water holding capacity, and palatability attributes. The impact of genetic factors such as breed variation and the influence of major genes (the Halothane and Rendement Napole genes), as well as relationships between carcass leanness and quality, are considered. In addition, the effect of nutrition, including vitamins and minerals, feeding level, and dietary energy:protein ratio, on pork quality is reviewed. Finally, the impact of diet on fat composition and quality is summarized.

  • Purpose: A Study on the application of quality management system specification to production validation and audit in military airworthiness certification. Methods: Aircraft quality management system specification for quality assurance and production validation and audit requirements were examined to verify. Also, the system for domestic and foreign production certification were investigated. Results: Production validation and audit criteria for military aircraft by applying methods suggested Aircraft Certifications Systems Evaluation Program(ACSEP). ACSEP evaluation of the items, some items were complementary and not applied. Conclusion: As a way to ensure the safety of aircraft, confirm the correction of Production validation & audit criteria and rulemaking is necessary and how to manage for Critical Safety Item(CSI) is a need to improve.

  • In front of the opening of electric distribution market in 2004, it is indispensable to have a proper estimation of power quality index and rower quality cost calculation mechanism which are indispensable to stabilize highly industrialized society and to vitalize the Investment lot electric power system. However, there were not enough measures to reflect the voltage characteristics such as voltage sags and Interruptions which make electric load in unstable operation. This paper suggests power quality index and power quality cost which translate various kinds of voltage records into bus load drop index(BLDI) and bus power quality cost(BPQC) based on aggregated load CBEMA curve. A sample calculation result shows that this method can produces the acceptable power Quality index and costs for utilities and customers requirements.

  • The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

  • Various M2M applications have different quality-of-service(QoS) requirements to be implemented practically. QoS requirements are normally data rate and delay constraint. However, there are limited number of wireless communication chip solutions which cannot support QoS requirements for all M2M application. Hence, aggregated usage of plural wireless communication chip solutions should be needed to implement M2M applications. In this paper, we consider the case that two wireless communication chips using random access protocol work together to transmit data of an M2M application. In such case, data rate and delay performance are mathematically analyzed. In our results, practical data rate can be improved from 2.5 to 7 times while delay constraints are satisfied if we simply use two wireless communication chips together.

  • This paper proposes a novel process which can develop the system requirements in defense R&D programs. As the weapon systems become more complicated, the success and effectiveness of R&D outcome heavily depend on the application and tailoring of systems engineering process and methods. And, the accuracy and quality of system requirements are essential prerequisite to leverage the systems engineering process. To produce the artifacts of systems engineering such as OCD, ORD, and the systems requirements, the system user can write out requirement document using the proposed implementation process and templates without expending heavy work loads.

  • An image data compression method for a digital VCR must satisfy special requirements such as high speed playback. various edting capabilities and error concealment to provide immunity to tape dropouts. Taking these requirements requirements into consideration, this paper proposes a new interframe subband coding algorithm for a digital VCR. In the proposed method, continuous input images are fist partitioned into four frequency bands. The lowest frequency subband is coded with 3-D block adaptive quantization that removes the level redundancy within each level. The other higher frequency subbands are coded by an intraframe coding method using the property of the human visual system. To keep reasonable image quality in high speed palyback, a segment forming method in the frequency domaing is also proposed Computer simulation results demonstrate that the proposed algorithm has the potential of achieving virtually lossless compression in normal play and produces an image with less mosaic errors in high speed play.
