오늘날 정보화 사회에서 경쟁하는 기업들에 있어서 데이터품질 저하는 기업경쟁력 하락과 새로운 비용창출이라는 부정적인 영향요인으로써 작용하고 있다. 이러한 데이터품질 저하의 문제를 해결하기 위해 데이터품질에 대한 많은 선행연구들이 진행되어 왔으며, 데이터품질의 측면 중 결과적 이고 현상적인 품질개념인 데이터 값의 품질과 데이터서비스의 품질에 대해 주로 연구되어 왔다. 이에 반해 본 연구에서는 원인적인 데이터품질 개념인 데이터의 구조적 품질을 메타데이터 관리의 관점에서 연구하였으며, 이를 통해 평가와 개선을 위한 관리의 관점이 적용된 데이터품질관리 성숙도모델을 제시하였다. 또한 본 연구에서 제시한 데이터품질관리 성숙도모델의 타당성 검증을 위해 데이터품질 관리단계가 성숙될수록 데이터품질수준이 높아지게 된다는 것을 실증적으로 검증하였다.

As the electronic commerce has grown dramatically, visiting the Internet shopping malls is accepted as one of our daily life. Despite many studies about user acceptance of the Internet shopping malls, it still remains unanswered how the Internet shopping mall's three quality factors such as system qualify, Information qualify, and service quality affect user trust, and eventually user acceptance of the mall. To investigate this issue, we propose a research model in which six external factors such as three qualify factors as well as self-efficacy, subjective norm, and trust have a significant impact on user's attitude and intention to use the mall. After garnering 244 valid questionnaires from users, we analyze them with structural equation modeling. Experiment results show that the Internet shopping mall's three quality factors such as system quality, information qualify, and service quality significantly Influence user trust for the mall, which in turn impacts user's perceived usefulness, attitude toward using the mall. Another external factors such as self-efficacy and subjective norm also influence user's perceived ease of use and perceived usefulness respectively, affecting user's attitude altogether. Implications and further research directions are presented.

The purpose of this research is to study the effect of service qualify improvement strategy and its practices on firms' competitive advantage, and identify their influence on customer satisfaction and loyalty. According to this purpose. this paper hypothesized that high service qualify will satisfy customers' needs and result in improved customers' loyalty. Thus, empirical study was conducted to identify the relationships among factors which were identified through literature review. Data were collected from the customers of 3 luxurious japanese restaurants in Seoul. The result of data analyses shows (1) Serve quality factors such as customer service, qualify of meal, location and facility, and types of restaurants make significant difference among three restaurants in terms of customers' perception about service quality; (2) There is statistically significant difference among three restaurants in terms of customers' satisfaction, but there is no significant difference among them in terms of customers' loyalty; and (3) Not only the result from analysis on japanese restaurants inside hotels but also that on the independent japanese restaurant in Kangnam area, shows that service quality factors have significant effect on both customers' satisfaction and loyalty.

UDDI 서버는 웹 서비스를 등록하고 검색하는데 사용되는 레지스트리다. 그러나 일반적으로 UDDI 서버는 웹 서비스의 품질에 관한 정보를 제공해주지 않기 때문에 웹 서비스 사용자가 품질 좋은 웹 서비스를 선택하기 위해서는 웹 서비스의 품질에 대한 정보를 제공해주는 중개자와 웹 서비스의 품질을 모니터링하기 위한 측정 요소가 필요하다. 본 논문에서는 웹 서비스의 품질을 모니터링하고 모니터링 결과를 웹기반으로 제공해주는 UDDI 중개자 시스템을 설계하고 구현하였다. 이 UDDI 중개자 시스템은 웹 서비스의 품질 정보를 수치와 그래프로 보여줌으로써 사용자가 품질 좋은 웹 서비스를 선택할 수 있게 해준다. 우리 연구에서는 사용가능성, 성능, 그리고 안정성 측면의 품질을 모니터 링의 측정 요소로 삼았다.

In the era of the internet and ubiquitous computing, IS users are still facing a variety of threats. Therefore, a need of more tightened information security service increases unprecedentedly. In this sense, this study is aimed at proposing a new research model in which IT assets (i.e., network, system, and information influence) Security and Information Security Service (i.e., confidentiality, integrity, nonrepudiation, authentication) affect information security quality positively, leading to users' satisfaction eventually. To prove the validity of the proposed research model, PLS analysis is applied with valid 177 questionnaires. Results reveal that both IT assets Security and Information Security Service influence informations security qualify positively, and user satisfaction as well. From the results, it can be concluded that Korean government's recent orchestrated efforts to boost the IT assets Security and Information Security Service helped great improve the information security quality and user satisfaction.

As service firms continue to seek unique sources of sustainable competitive advantage, service quality has been discussed as a potential alternative to traditional skills and sources. The information of customers is generally believed to be a key component in creating corporate responsiveness to customer requests. In order to develop and maintain long-term close relationships with customers, service firms need to build an effective and ongoing service qualify information system(SQIS). Service firms that formally collect customer-related information and internal service quality information were to be more responsive. Accordingly, the purpose of the present study is twofold. 1. How to get the information on the service quality. 2. How to build a SQIS. An analysis is conducted of SQIS into input, process and output staging. One of numerous examples from financial service-sector firms is given to show SQIS can be developed to improve service qualify. Implications and strategies for building an effective SQIS for financial service-sector firms are discussed, and directions for future research are indicated.

In this paper, I investigate the impact of quality management activities on the public sector within the framework of Malcolm Baldrige (MB) national qualify model. The Structural Equation Modeling approach has been employed to investigate the cross influences among the seven MB categories. This empirical study shows that a number of statistical hypotheses are significant. The leadership category is the most important driver among the quality management activities. This, in turn, implies that the main source in quality management is to foster a solid qualify oriented leadership system. Categories such as Information Analysis, Strategic Planning, Human Resource Development and Management, and Process Management are significantly related to the Customer Satisfaction category. In addition, leadership, Information Analysis, and Customer Satisfaction categories ere significantly influential to Management Performance.

Recently, the increasing application of electronic equipments and information devices has heightened the interest in power qualify. The term power quality is applied to a wide range of electromagnetic phenomena on the power system and is also concentrated by all areas such as utilities, their customers and suppliers of load equipments. In engineering terms, power Qualify is expressed by voltage qualify because the power supply system can only control the quality of the voltage. Therefore, the standards in power quality area are devoted to keep the supply voltage within allowable limits. This paper deals with single-phase unified power quality conditioner (UPQC), which ai s at the integration of series-active and shunt-active filter. The series filter il used to compensate for the voltage distortions and the shunt filter is used to provide reactive power and counteract the harmonic current injected by the load. Also, the voltage of the DC link capacitor is controlled to a desired value by the shunt active filter. The validity of the proposed UPQC is demonstrated using both the MATLAB/SIMULINK simulation and the experimental device with DSP (TMS320C32).
