Software quality is strongly associated with requirement quality. Accordingly, companies are trying effect for enhancing requirement quality. But, it is difficult to verify the requirement of specification format, which have to rely on abnormal business knowledge of analyst. Also, it is insufficient to normal methodology or automated technique for enhancing requirement quality of specification format. In this paper, we propose the process of requirement verification and automated verification tool for enhancing requirement quality. we compare the external view design and internal view design for verifying requirement. In the case study, we evaluate the feasibility of the proposed automated verification technique of requirement.

In this paper, we propose a quality assessment method of biometrics for estimating an authentication result in an user authentication system. The proposed quality assessment method is designed to compute a quality score called CIMR (Confidence Interval Matching Ratio) as a result by small-sample analysis like T-test. We use the C/MR-based quality assessment method for testing how to well draw a distinction between various biometrics in a multimodal biometric system. We also test a predictability for authentication results of obtained biometrics using the mean $\bar{X}$ and the variance $s^2$ in T-test-based CIMR. As a result, we achieved the maximum 88% accuracy for estimation of user authentication results.

According to technical advances of telecommunication, communication network has changed to digital transmission from analog transmission network. In the long run, current network will be altered into ISDN which makes end-to-end digital communication. This transition of communication network brings about an important questions for networking plan, administration, and speech quality in order to achieve the effective and advanced telecommunication. Speech quality criterions and degradation factors of digital communication system differ from those of existing analog system because of other characteristics like single echo. It is, therefore, necessary to design new criterions and specifications for digital communication network. This Paper describes the relation between speech communication and speech transmission quality and describes the implementation of model system for quality evaluation of digital speech communication network. In addition, some applications of model system implemented are proposed.

Usability is defined by the effectiveness efficiency and satisfaction with which specified users can achieve a specified goal in the particular environment. This paper is not only to provide a framework for specifying the usability attributes of a product and establishing a comprehensive set of usability criteria, but also to asses usability metrics of the software. The Evaluation Tool for Software Usability are developed based on the properties of the a user interface using ISO standard and general usability principles with product-oriented view. It means that product has attributes contributing to determine the usability. This paper also suggests the way to weight the relative importance of the individual usability item depending on the software categories.

Increased over time are the market size of coffee shops and customer demands for coffee. This paper aims to provide solutions for quality improvement in products and services of coffee shops through a case study. SERVQUAL is adopted and modified for the given problem to identify customer requirements for services of coffee shops. Quality Function Deployment (QFD) is introduced as an effort to reflect customer requirements in engineering characteristics for products and services. This paper compares the market competitiveness of three coffee shops in a case study. This study also draws solutions for quality improvement in engineering characteristics for products and services by using QFD.

In the application development process is an important task to improve the quality of the data is the principal means for achieving the functional requirements of the wireless sensor network applications because it is the data obtained in the real world. It should be possible to meet the requirements for the quality improvement to those detailed for improving the quality in a short period of time for developing a prototype of an application and low cost. However, development of the existing methods can not be satisfied simultaneously in order to use a consistent abstraction because antinomical relation between ability of description and ease of description. In this paper, we propose a meta-data designed to support the improvement of data quality through abstract modeling language is also used in combination to a multiple of the other.

For successful waterproofing construction, it is very important to secure construction quality as well as material performance of waterproofing materials used in construction. Due to the long-term cost reduction policy following the economic downturn in the construction market, most construction companies are using general low-priced waterproof materials rather than high-quality waterproof materials without clear quality control standards. Without clear education on construction, construction is being carried out with meaning only on construction activities. In addition, the waterproofing method applied in combination is a situation where water leakage occurs due to waterproofing failure due to insufficient construction quality because the construction method is complicated. Therefore, it is necessary to review the quality control measures(design, materials, construction) for successful waterproofing work and improve problems that are derived so that stable waterproofing work can be done. In order to expect the leakage prevention effect of a building, first, it is required to select appropriate materials for each part of the building and environment in the design stage, and the selected materials must satisfy all items of the Korean Industrial Standard(KS). Second, to secure the quality of waterproofing construction, sincere construction by workers is required. In this paper, we tried to describe "review of waterproof design", "constructor education", "site inspection", and "criticism(correction/supplementation)" as quality control measures after material selection.

ATM switching software should be required high reliability, functionality, extendability and maintainability. After development of the software, it is verified and tested by analyzer whether the software is accomplished the characteristics of it or not. There are so many CASE tools in other area, but the CHILL testing tools that can verify ATM softwares have not various functions are not many. In this paper we develop the testing tool which can evaluate and test CHILL programmed ATM software. This Tool supports testing reports, debugging informations and maintenance informations including parallel process about CHILL original programs.

게임이 기획, 그래픽, 프로그램의 복합적 기능을 가진 콘텐츠이지만 특별히 수준 높은 그래픽 데이터는 이용자의 만족도, 몰입 등에 긍정적인 영향을 미치는 중요한 영역이다. 그러나 아직 국내외에 게임 그래픽 데이터의 품질을 객관적으로 평가할 수 있는 기준이 마련되어 있지 않다. 이에 따라 본 논문에서는 게임 그래픽 데이터의 품질 평가를 위한 지표를 개발하는 프로세스를 제안한다. 제안된 프로세스는 그래픽 데이터의 품질 평가 영역 추출을 위한 방법과 세부 평가 지표 마련을 위한 평가 항목 추출방법들로 구성된다. 본 연구 결과는 고품질 게임 개발을 위한 품질평가 지표 개발에 적용될 것이며 관련 분야의 품질평가 모델 개발의 참조 모델이 될 것이다. 향후 본 연구는 국내외 게임 그래픽 데이터의 품질평가 표준안 설계 개발로 진행될 예정이다.
