  • 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.

  • 기업에서 관리하여야 하는 데이터의 양이 급속히 증대함에 따라 데이터의 품질관리 문제가 대두되고 있다. 또한 데이터의 통합이 이루어지지 않아 중복관리, 저품질의 정보제공, 특정 데이터의 누락 등의 문제가 발생하고 있어 본 연구에서는 메타데이터를 활용한 데이터 품질관리 방안을 모색한다. 이를 위해 메타데이터의 의의 및 다양한 메타데이터 관리 현황을 분석하고, 실무자와의 인터뷰를 통해 컨테이너터미널을 대상으로 메타데이터 관리 방안을 제시하였다. 주요 연구 내용은 A사의 메타데이터 관리를 위해 데이터 표준화 과정을 수행하였으며, 제약 조건 및 조정 사항 등을 메타데이터 레파지토리에 반영하였다. 본 연구의 공헌도는 제시된 관리 방안을 통해 A사의 데이터 품질 문제를 개선할 수 있다는 것과 해당 도메인을 대상으로 메타데이터 관리 방안을 적용하였다는데 있다. 본 연구의 한계점은 관리 방안이 일부분의 업무에만 적용되었다는 점이며, 향후 기업과 기업간의 통합을 위한 메타데이터 관리 방안에 대한 연구가 필요하다.

  • The Data quality management system(DQMS) organizes and helps manage and process time sequence data usually collected in monitoring networks and programs. DQMS places particular emphasis on data qualify while maintaining a highly organized and convenient structure for data. It operates with in a flexible and powerful commercial relational data base environment which can readily link to other software platforms from local spreadsheets to network server. The Korea Institute of Energy Research(KIER) has been solar radiation data since May, 1991 for 16 different locations. KIER's new data is expected to be extensively used by designer and researchers of solar systems in lieu of unreliable old ones. Unfortunately, the quality of the data has not always been properly mentioned. The purpose of this study is to systematically identify errors in such data set using DQMS in an effort to rehabilitate error-ridden old data. DET successfully uncovered solar radiation data that had questionable quality.

  • The purposes of this study were to identify the service quality, quality of relationship, and relationship continuity intention of rental clothing store. Questionnaires developed by researcher were collected from 212 consumers who experienced rental clothing. Data was analysed by use of factor analysis, path analysis, and covariance structure analysis. The results were; 1. Factors of service quality of clothing rental store were tangibility & promotion, shop assistant & store atmosphere, customer empathy, customer reliability strategy, customer management, and customer convenience. And factors of relationship quality were satisfaction, trust, emotional involvement, and calculational involvement, and factors of relationship continuity intention were longitudinal relationship propensity & word-of-mouth and rerental intention. 2. Service quality of rental store affected significantly on relationship quality, and relationship quality affected significantly on relationship continuity intention. And service qualify of rental store affected significantly on relationship continuity intention through relationship qualify.

  • In order to provide personalized knowledge recommendation services, most web portals for organizational knowledge management use category or keyword information that portal users explicitly express interests in. However, it is usually difficult to collect correct preference data for all users with this approach, and, moreover, users' preferences may easily change over time, which results In outdated user profiles and impaired recommendation qualify. In order to address this problem, this paper suggests knowledge recommendation methods for portals using user profiles that are automatically constructed from users' activities such as posting or uploading of articles and documents. The result of our experiment shows that the Proposed method can provide equivalent performance with the manual category or keyword selection method.

  • Gears are essential elements for mechanical power transmission. Geometric precision is the main factor for characterizing gear grade and qualify. Gear pitch is one of the crucial measurements, which is defined as a distance between two adjacent gear teeth. It is well-known that variability in gear pitches may causes wear-out and vibration noise. Therefore maintaining pitch errors at a low level plays a key role in assuring the gear quality to customers. This paper is concerned with a case study, which presents a computerized system for Inspecting pitch errors in a gear machining process. This system consists of a PC and window-based programs. Although the start and stop is manually accomplished, the process of measuring and analyzing pitch data is automatically conducted in this system. Our purpose lies in reducing inspection cost and time as well as Increasing test reliability. Its operation is briefly illustrated by example. Sometimes a strong autocorrelation is observed from pitch data. We also discuss a process monitoring scheme taking account of autocorrelations.
