정보시스템의 효과적인 개발 및 운영을 지원하기 위한 활동에는 품질 보증, 감리 등이 있다. 이중에서 감리는 정보시스템의 전체 개발 수명주기에 걸쳐서 시스템의 품질을 개선시키기 위한 핵심활동이라고 할 수 있다. 현재 공공 정보시스템 감리는 기존의 정보시스템감리기준(정보통신부고시제1999-104호)를 활용하여 수행하고 있지만, 감리영역이나 점검사항이 현재 IT 환경과 맞지 않고 실제 감리에 적용하기 어렵다. 또한, 정보시스템 개발수명주기에 걸쳐서 감리를 수행해야함에도 불구하고, 현실은 그렇지 않으며 수명주기별 감리기준도 명확하지가 않다. 본 연구에서는 ISACA(Information Systems Audit and Control Association)의 COBIT(Control Objectives for Information and related Technology)와 IT 관련 국제 표준들을 벤치마킹하여 정보시스템 감리프레임워크를 제시하였고, 이의 운영 및 활용 방안을 제안하였다.

Munitions must be analyzed to identify any risks for quality assurance in development and mass production. Risk identification for parts, compositions, and systems is carried out through failure mode effects analysis (FMEA) as one of the most reliable methods. FMEA is a design tool for the failure mode of risk identification and relies on the RPN (risk priority number). FMEA has disadvantages because its severity, occurrence, and detectability are rated at the same level. Fuzzy FMEA applies fuzzy logic to compensate for the shortcomings of FMEA. The fuzzy logic of Fuzzy FMEA is to express uncertainties about the phenomenon and provides quantitative values. In this paper, Fuzzy FMEA is applied to the failure mode of a rotorcraft landing system. The Fuzzy rule and membership functions were conducted in the Fuzzy model to study the RPN in the failure mode of a landing system. This method was selected to demonstrate crisp values of severity, occurrence, and detectability. In addition, the RPN was obtained. The results of Fuzzy FMEA for the landing system were analyzed for the RPN and ranking by fuzzy logic. Finally, Fuzzy FMEA confirmed that it could use the data in quality assurance activities for rotorcraft.

The purpose of this study is to measure the library online service quality based on the expectation and the service performance from the users' point of view. The online questionnaire was developed based on SERVQUAL, however information quality dimension was added on it, and the survey was conducted within a research library. The factor analysis for effecting library online services showed that 5 service dimensions were loaded discretely, and information quality was put in the other dimension. The IPA (Important Performance Analysis) result confirmed that information quality, service reliability, and service assurance were considered as important factors : multiple regression analysis revealed that tangibility and information quality were the most significant dimension for the library online service.

This study examines an evaluation on the effect of service quality of food products on tourist satisfaction. Style, pleasantness, reliability, kindness, and guarantee were selected as service quality factors for this study. Also, expected effects, purchase intention, and repurchase intention were used to examine tourists' satisfaction levels. To verify the relationship between the service quality of food products and tourist satisfaction, it used one hundred twenty sample cases. The results service quality are as follows. First, the types of service quality were drawn based on the characteristics of service quality. Second, the service quality of food products had positively significant influence on the satisfaction levels of purchase behavior. Third, the types of service quality and the satisfaction levels of purchase behavior were significantly different.

QoS(Quality of Service) is defined as "The collective effect of service performance which determines the degree of satisfaction of a user of the service" by ITU-T Rec. E.800. While the use of VoIP(Voice Over Internet Protocol) has been widely implemented, persistent problems with QoS are a very important sue which needs to be solved. This research is finding the assignment of VoIP QoS to deduct how to manage the control system and presenting the QoS control process and framework under NGN(Next Generation Network) environment. The trial framework is the modeling of the QoS measurement metrics, instrument, equipment, method of measurement, the series of cycle & the methodology about analysis of the result of measurement. This research underlines that the vulnerability of the VoIP protocol in relation to its QoS can be guaranteed when the product quality and management are controlled and measured systematically. Especially it's very important time to maintain the research about VoIP QoS measurement and control because the big conversion of new network technology paradigm is now spreading. In addition, when the proposed method is applied, it can reduce an overall delay and can contribute to improved service quality, in relation to signal, voice processing, filtering more effectively.

Currently, Building Information Modeling (BIM) is an emerging technological shift that involves applying and maintaining an integral digital representation of all building information for different phases of the project life-cycle. Although BIM has been recognized as a main stream in the construction industry, it is difficult to ensure the quality of BIM data due to the problems such as internal errors of BIM tools and lack of guidelines considering design quality. Such problems give lots of difficulties to BIM adoption for designers, constructors, and owners. Therefore, it is necessary to develop the requirements including the object-oriented modeling method and property definition by applying the Industry Foundation Classes (IFC) which is an ISO/PAS 16739 standard for ensuring the quality of BIM data. This research aims at proposing the requirements considering the quality of BIM data and demonstrating the efficiency of the requirements with using the Solibri Model Checker (SMC) which is a quality control tool in a case study.

As BIM is now being accepted and broadly expanded in the building industry, the demand for developing, managing, submitting, and checking the BIM models has increased. To meet this demand, it is necessary to develop and spread BIM guidelines, standards, and manuals. Meanwhile, as the number of public construction projects increases, the importance of quantifying the BIM quality checking and evaluation also grows. This study aims to enhance our understanding of the definition and characteristics of BIM quality management, and review the current situation of BIM standards worldwide. In particular, by focusing on BIM quality control and its relevant subjects, the minimum standards for BIM quality management are suggested.

Testing and evaluation was carried out to certify quality assurance of localized engine parts using accelerated mission test method, which has been used to verify qualification or substantiation of the developed engine, improved engine components and engineering changed parts since 1976. Because AMT is not a familiarized testing for quality assurance of engine and localized engine parts in korea, through this testing and evaluation, it is presented the concepts, test procedures and evaluation method of AMT and is proposed the possibility of execution AMT, as a tool for qualification or substantiation test of a development engine or components.

An early detection system for warranty issues periodically collects customers' claim data and automatically reports alarms about emerging issues based on statistical algorithms. It helps companies to reduce an issue definition time and save the handling cost of warranty claims. This paper provides an evaluation framework to validate the economic effect of an early detection system project. For this purpose, we present economical index of a project with explicit formulas such as ROI(return on investment), PP(payback period), NPV(net present value), PI(profitability index) and IRR(internal rate of return) and analyze the sensitivities of the index according to the variation of project input parameters. The proposed analysis framework is expected to be used for evaluating economic values of various system integration projects.

To successfully carry out large scale research projects while su, pp.rting quality assurance of research output, effective and systematic management through utilization of resources such as manpower, time and cost as well as engineering techniques such as component technology and design methodology is required. It is necessary to establish development methodology to su, pp.rt quality assurance. The development methodology covers the contents and procedures of the project, such as division of the project into independently executable units, allocation of resources including researchers, component technology, related know-how and equipment, deployment of research units and integration of the project at the end. In this paper we present systematic development methodology for quality assurance in large scale software development projects by analyzing the contents of the methodology a, pp.ied to the Gigabit Information-processing And Networking Technology development project(GIALT).
